    FIELD OF THE INVENTION [0001] The present invention relates to the technical field of smart households, and in particular, to a water overflowing preventing washbasin.
    BACKGROUND OF THE INVENTION [0002] A washbasin is a basic facility in a domestic sanitary system, and is usually composed of a tap and a hand basin. The tap communicates with a tap-water pipe, and a bottom portion of the hand basin communicates with a sewer pipe. When using the washbasin, a user may turn on the tap to wash hands or face in the hand basin by using tap water. During actual use of the washbasin, cases in which water in the hand basin overflows because the user forgets to turn off the tap frequently occur. As a result, other articles in a room are damaged because of being soaked by water. For example, wooden floor deforms after being soaked by water.
    [0003] Refer to FIG. 1. FIG. 1 is a schematic diagram of an existing water overflowing preventing washbasin. The water overflowing preventing washbasin includes a hand basin 1 and a tap 2 disposed on the hand basin 1. A bottom portion of the hand basin 1 is provided with a sewer nozzle 12, and a sewer switch 11 is disposed on the sewer nozzle 12. The tap 2 is disposed on the hand basin 1. The tap 2 includes a faucet 21 and a handle 22 disposed on the faucet 21. The tap 2 communicates with a tap-water pipe, and on and off of the faucet 21 may be controlled by using the handle 22. The sewer nozzle 12 communicates with a sewer pipe 3, and on and off of the sewer nozzle 12 may be controlled by using the sewer switch 11. An inner wall of the hand basin 1 is further provided with an overflow hole 13. The overflow hole 13 communicates with the sewer nozzle 12. When a water level in the hand basin 1 reaches a height of the overflow hole 13, water may be drained from the hand basin 1 through the overflow hole 13, to control the water level in the hand basin 1 to be lower than the height of the overflow hole 13, thus avoiding overflow caused by an excessive high water level in the hand basin 1.
    [0004] However, although the foregoing existing water overflowing preventing washbasin can avoid overflow in use, when the user forgets to turn off the tap, excess water in the hand basin is directly drained from the sewer pipe through the overflow hole. In this case, although overflow is avoided, a lot of water resources may be wasted before the user turns off the tap.
    SUMMARY OF THE INVENTION [0005] An objective of the present invention is to provide a water overflowing preventing washbasin, to resolve a problem that an existing water overflowing preventing washbasin may result in wastes of water resources.
    [0006] This application provides a water overflowing preventing washbasin, including a hand basin and a tap disposed on the hand basin, the tap including a faucet and a handle disposed on the faucet, where the water overflowing preventing washbasin further includes a lifting bar, a water level monitoring device, a lifting bar driving device, and a controller;
    a basin wall of the hand basin is provided with a cavity, the cavity is located at a bottom portion of the tap, the lifting bar is disposed at an upper surface of the hand basin in a vertical manner, the lifting bar is located at one side of the tap, a top portion of the lifting bar extends to be above the handle, a bottom portion of the lifting bar extends into the cavity, the water level monitoring device is disposed at a basin wall surface within the hand basin, and the lifting bar driving device and the controller are disposed in the cavity;
    the water level monitoring device is electrically connected to the controller, and is configured to send a tap off signal to the controller after it is detected that a water level in the hand basin reaches a preset water level;

    [0007] In actual applications, a user can turn on the handle in an upward direction, so that tap water flows from the faucet to the hand basin, to enable the user to perform cleaning operations on hands, face, and the like in the hand basin. When the user temporarily leaves the washbasin without turning off the tap, and a sewer switch at a bottom portion of the hand basin is also turned off, a height of the water in the hand basin gradually increases. When a water level in the hand basin rises to a preset height that can be detected by the water level monitoring device, the water level monitoring device sends a tap off signal to the controller, so that the controller can control the lifting bar driving device to operate, to drive the lifting bar to descend. The handle of the tap is pressed down by using the lifting bar, to automatically turn off the tap. After the tap is turned off, the controller can control the lifting bar driving device to operate, to drive the lifting bar to ascend to be reset.

    DETAILED DESCRIPTION OF THE EMBODIMENTS [0015] Refer to FIG. 2 to FIG. 4. An embodiment of this application provides a water overflowing preventing washbasin, including a hand basin 1 and a tap 2 disposed on the hand basin 1. The tap 2 includes a faucet 21 and a handle 22 disposed on the faucet 21. The water overflowing preventing washbasin further includes a lifting bar 4, a water level monitoring device 5, a lifting bar driving device, and a controller 9.
    [0016] The hand basin 1 may be made of glass, a ceramic material, or a metal material. A cavity 10 is disposed within a basin wall of the hand basin 1, and the cavity 10 is located at a bottom portion of the tap 2. The lifting bar 4 is disposed at an upper surface of the hand basin 1 in a vertical manner, and is located at one side of the tap 2. A top portion of the lifting bar 4 extends to be above the handle 22, and the lifting bar 4 is configured to automatically press down the handle 22 while descending, to turn off the tap 2. A bottom portion of the lifting bar 4 extends into the cavity 10.
    [0017] The water level monitoring device 5 is disposed at a basin wall surface within the hand basin 1, and the lifting bar driving device and the controller 9 are disposed in the cavity 10. The water level monitoring device 5 is electrically connected to the controller 9, and is configured to send a tap off signal to the controller 9 after it is detected that a water level in the hand basin 1 reaches a preset water level. The controller 9 is electrically connected to the lifting bar driving device, and is configured to control the lifting bar driving device to operate after the tap off signal is received. The lifting bar driving device is connected to the portion that is of the lifting bar 4 and that extends into the cavity 10, and is configured to drive, under control of the controller 9, the lifting bar 4 to descend to drive the handle 22 to be turned off, and to drive the lifting bar 4 to ascend after the handle 22 is turned off. In this case, the tap is automatically turned off after the water level in the hand basin reaches a preset height. In this way, while the water in the hand basin is prevented from overflowing because the tap keeps discharging the water, wastes of water resources are avoided.
    [0018] Refer to FIG. 4. As an optional implementation, the lifting bar 4 includes a horizontal portion 42 and a vertical portion 41. One end of the horizontal portion 42 is connected to a top portion of the vertical portion 41 in a vertical manner. The horizontal portion 42 and the vertical portion 41 may be connected in an integral manner. An upper surface of the hand basin 1 is provided with a lifting hole 14 communicating with the cavity 10. A size of the lifting hole 14 matches with that of the vertical portion 41. A bottom portion of the vertical portion 41 extends into the cavity 10 through the lifting hole 14. A protection tube that protrudes relative to the upper surface of the hand basin 1 may also be disposed at a position of the lifting hole 14. A bottom portion of the protection tube communicates with the lifting hole 14. The vertical portion 41 is located within the protection tube, so that water at the upper surface of the hand basin 1 may be prevented from flowing into the cavity 10 through the lifting hole 14, to avoid adverse impacts on the lifting bar driving device and the controller 9.
    [0019] The bottom portion of the vertical portion 41 is provided with a guide channel 412. The guide channel 412 is specifically disposed at the portion that is of the vertical portion 41 and that extends into the cavity 10. The guide channel 412 penetrates a front surface and a back surface of the vertical portion 41, and extends along a vertical direction. A guide post 413 is disposed in the cavity 10. A diameter of the guide post 413 is equal to a width of the guide channel 412, and the guide post 413 passes through the guide channel 412 in a vertical manner.When the lifting bar 4 ascends or descends, the guide channel 412 may perform guiding and limiting operations by using the guide post 413. A top portion and a bottom portion of the guide channel 412 may be provided to have arc shapes that fit with the diameter of the guide post 413, to improve stability when the guide post 413 is in contact with a top end and a bottom end of the guide channel 412.
    [0020] As an optional implementation, a side portion of the vertical portion 41 is provided with a plurality of drive gears 411 that are evenly distributed from top to bottom. The lifting bar driving device includes a motor 6, a driving gear 7, and a driven gear 8. The motor 6 is disposed at a bottom portion of the cavity 10, and is electrically connected to the controller 9. The bottom portion of the cavity 10 may be provided with a motor base on which the motor 6 is fixed on. The controller 9 may be fixed in the cavity 10 by using a screw.
    [0021] The driving gear 7 is disposed on an output shaft of the motor 6. A gear shaft 81 is disposed above the motor 6. The gear shaft 81 is disposed to be parallel to the guide post 413. The driven gear 8 is disposed on the gear shaft 81. The driving gear 7 is engaged with the driven gear 8, and the driven gear 8 is engaged with the drive gear 411.
    [0022] After receiving the tap off signal, the controller 9 may control the output shaft of the motor 6 to rotate clockwise, to drive the driving gear 7 to rotate clockwise, and the driving gear 7 further drives the driven gear 8 to rotate anticlockwise. The driven gear 8 drives the lifting bar 4 to descend by using the drive gear 411, thus pressing down the handle 22 of the tap 2 by using the horizontal portion 42 of the lifting bar 4, thereby automatically turning off the tap 2.
    [0023] Refer to FIG. 3 and FIG. 4. As an optional implementation, the water level monitoring device 5 includes a shell 51, a sensor mounting base 52, and an optoelectronic liquid-level sensor 53. The shell 51 is in a cuboid shape, and is disposed in an edge region within the hand basin 1 in a vertical manner. A height of the shell 51 fits with a depth of the hand basin 1. The sensor mounting base 52 is disposed on the shell 51. The optoelectronic liquid-level sensor 53 is disposed within the sensor mounting base 52, and is electrically connected to the controller 9.
    [0024] Because a near-infrared light-emitting diode and a photoreceiver are usually included in the optoelectronic liquid-level sensor 53, light emitted by the light-emitting diode is guided into a lens at a top portion of the sensor. If the optoelectronic liquidlevel sensor 53 is not in contact with a liquid, the light emitted by the light-emitting diode is directly reflected to the photoreceiver from the lens. When the lens of the optoelectronic liquid-level sensor 53 is imsersed in the liquid, the light emitted by the light-emitting diode is refracted into the liquid, so that the photoreceiver cannot receive the light or can merely receive a small amount of light. By sensing the foregoing changes, the optoelectronic liquid-level sensor 53 can send the tap off signal to the controller 9 and turn off the tap 2 in a timely manner, thereby preventing the water from overflowing from the hand basin 1.
    [0025] Refer to FIG. 5. As an optional implementation, a guide rail 511 extending in a vertical manner is disposed on the shell 51. Chutes 512 extending in a vertical manner are disposed at both sides of the guide rail 511. Sliders 521 are disposed at both ends of the sensor mounting base 52, and the sensor mounting base 52 is disposed within the guide rail 511. The slider 521 is connected to the chute 512 in a sliding manner. The sensor mounting base 52 can slide up and down within the guide rail 511, to freely adjust a height of the sensor mounting base 52. In this way, a user can freely adjust a position of the optoelectronic liquid-level sensor 53 according to actual use requirements, to set a highest water level in the hand basin 1.
    [0026] An adjustment rod 522 is disposed at one end that is on the sensor mounting base 52 and that faces an inner side of the hand basin 1. The adjustment rod 522 is composed of multiple sections of sub-adjustment rods that are hingedly connected, and a magnet 523 is disposed at a surface of the adjustment rod 522. An adjustment channel extending in a vertical manner is disposed at a position at which a side wall of the shell 51 corresponds to the adjustment rod 522. The adjustment rod 522 extends outside the shell 51 after passing through the adjustment channel. A side that is at a surface of the shell 51 and that is close to the adjustment rod 522 is provided with a strip-shaped iron sheet 524 that is disposed in a vertical manner.
    [0027] When the position of the optoelectronic liquid-level sensor 53 needs to be adjusted, the user can take off the magnet 523 attracted on the strip-shaped iron sheet 524, and move up and down the adjustment rod 522 within the adjustment channel, to adjust the height of the sensor mounting base 52 in the guide rail 511. After the sensor mounting base 52 is adjusted to a proper height, the adjustment rod 522 can be bent toward the strip-shaped iron sheet 524, so that the magnet 523 on the adjustment rod 522 is attracted on the strip-shaped iron sheet 524. In this way, the position of the sensor mounting base 52 is fixed.
    [0028] As an optional implementation, a top end of the guide rail 511 is provided with a cable hole, and a connection cable between the optoelectronic liquid-level sensor 53 and the controller 9 extends into the cavity 10 after passing through the cable hole. A length of the connection cable between the optoelectronic liquid-level sensor 53 and the controller 9 needs to fit with an adjustment track of the sensor mounting base 52. The cable hole is disposed at the top end of the guide rail 511, so that the water in the hand basin 1 may be prevented from entering the cavity 10 from the cable hole, to prevent the lifting bar driving device and the controller 9 in the cavity 10 from being damaged.
    [0029] As an optional implementation, a length of the horizontal portion 42 of the lifting bar 4 is greater than a double of a distance between the faucet 21 and the vertical portion 41 of the lifting bar 4. The handle 22 of the tap 2 usually has two positions for opening hot water and cool water in an opening status, and at the foregoing two opening positions, the handle 22 is respectively raised toward the upper left and the upper right of the faucet 21. Therefore, the length of the horizontal portion 42 needs to be set to be long enough, to ensure that the horizontal portion 42 of the lifting bar 4 can be in contact with the handle 22 during a descending process.
    [0030] Refer to FIG. 6. As an optional implementation, a bottom portion of the horizontal portion 42 is provided with a concave portion 421, and a rubber pad 422 is disposed in the concave portion 421. By providing the concave portion 421 and the rubber pad 422 at the bottom portion of the horizontal portion 42, the rubber pad 422 can be in contact with the handle 22 when the horizontal portion 42 descends, to increase a friction force between the horizontal portion 42 and the handle 22, thereby improving stability when pressure is applied downward to the handle 22, so as to ensure that the handle 22 is successfully turned off.
    [0031] Refer to FIG. 7, it may be learned from the foregoing technical solutions that when using the water overflowing preventing washbasin provided in this application, the user can turn on the handle 22 in an upward direction, so that tap water flows from the faucet 21 to the hand basin 1, to enable the user to perform cleaning operations on hands, face, and the like in the hand basin 1. When the user temporarily leaves the washbasin without turning off the tap 2, and a sewer switch at the bottom portion of the hand basin 1 is also turned off, the height of the water in the hand basin 1 gradually increases. When the water level in the hand basin 1 rises to a preset height that can be detected by the water level monitoring device, the water level monitoring device sends a tap off signal to the controller 9, so that the controller 9 can control the lifting bar driving device to operate, to drive the lifting bar 4 to descend. The handle 22 of the tap is pressed down by using the lifting bar 4, to automatically turn off the tap 2. After the tap 2 is turned off, the controller 9 can control the lifting bar driving device to operate, to drive the lifting bar 4 to ascend to be reset. In this way, while the water in the hand basin is prevented from overflowing because the tap 2 keeps discharging the water, wastes of water resources are avoided.
