    [0001] [0001] This application claims priority of a Chinese patent application filed with the Chinese Patent Office on December 26, 2018 with the application number 201811603673.0 and the invention title “INTELLIGENT AIR BLOWING HAND DRYER”, the disclosure of which is incorporated by reference in its entirety.FIELD OF THE INVENTION
    [0002] [0002] This application relates to the technical field of smart home, and in particular to an intelligent air blowing hand dryer.BACKGROUND OF THE INVENTION
    [0003] [0003] A hand dryer, also known as an automatic hand dryer, is an advanced and ideal sanitary cleaning device, having the characteristics such as large air volume, low noise, high sensitivity, convenient to use, fast. When a user has washed and put two hands into an air outlet of a hand dryer, the hand dryer will automatically blow out comfortable air, so that the two IS — hands are quickly dried from wetness. When the two hands leave the air outlet, the hand dryer will automatically stop the air and shut down. Therefore, a person’s hands do not have to touch a component such as a switch, effectively preventing the problem of cross infection of diseases.
    [0004] [0004] Generally, the air outlet of the existing automatic hand dryer has the same air volume and strength across various parts of two hands. However, in fact, because areas of places such as N 20 — finger gaps and finger roots of the two hands are small and the distances between fingers are = small, it is easy to block the blowing air, affecting the drying effect at the finger gaps and the S finger roots. However, the above positions are positions where bacteria and the like easily breed z and hide. Especially in wet environment of incomplete drying, it is more likely to aggravate this a potential situations so that hand drying does not achieve the desired effect. If the hidden 2 25 positions such as the finger gaps are to be dried thoroughly, a user needs to rub fingers with the O blowing air and also extend the air blowing time. Thus, it will not only greatly reduce the drying efficiency, but the rest of the two hands will become over-dried due to excessive drying. 1

    [0019] [0019] FIG. 5 is a structural block diagram of components related to a microprocessor in the intelligent air blowing hand dryer according to an embodiment of this application.
    [0021] [0021] An embodiment of this application provides an intelligent air blowing hand dryer, comprising a head part 1, a backboard 2, a tail part 3, a microprocessor 4 and a motor 5; the head part 1 and the tail part 3 are connected by the backboard 2; the microprocessor 4 and the motor 5 are arranged inside the head part 1, and the 20 microprocessor 4 is connected to the motor 5; S the head part 1 comprises an upper air box 11, a laser detector 12, an upper air baffle 13, N upper straight air outlets 14 and upper air passages 15; the upper air box 11 is spliced with the upper air baffle 13, and the upper air baffle 13 is 2 close to the tail part 3; the upper air baffle 13 is provided with the upper straight air outlets 14 a 25 — which are in communication with the upper air box 11; the upper air baffle 13 is provided with & the laser detector 12 on one side close to the tail part 3, and the laser detector 12 is connected to ä the microprocessor 4; the upper air passages 15 are provided inside the upper air box 11, and the upper air passages 15 are close to the upper air baffle 13 and correspond to the upper straight air outlets 14; the upper air box 11 is connected to the motor 5;
    [0022] [0022] When in use, the intelligent hand dryer is hung to a proper position on a wall through the backboard 2, so that the intelligent hand dryer is arranged in a vertical direction with the head part 1 above and the tail part 3 below. Of course, the head part 1 and the tail part 3 are IS mainly air blowing components, which provide double-sided air blowing for two hands. Therefore, in addition to the structure with the head part 1 above and the tail part 3 below disclosed in the embodiment of this application, an existing air blowing structure on the market can also be used, i.e., a U-shaped structure in which the head part 1 and the backboard 2 together are close to the wall and the tail part 3 is away from the wall corresponding to the head — part 1.
    [0023] [0023] After the power supply of the intelligent hand dryer is turned on, the upper air box 11 S and the lower air box 31 are driven by the motor 5 to start air supply. When two hands are N unfolded and placed between the head part 1 and the tail part 3, the laser detector 12 starts to recognize external contours of the two hands, or determines finger gap positions of the two 2 25 hands through techniques such as image grayscale recognition, and transmits contour a information to the microprocessor. Specifically, the laser detector 12 performs contour detection & for the two hands, and determines hidden positions such as the finger gaps through occlusion N and light changes on the hands. Furthermore, in order to enhance the recognition accuracy and - drying efficiency, a user should try to spread ten fingers as much as possible. In addition to the — laser detector 12 provided in the embodiment of this application to recognize contours of the 6
    [0024] [0024] The microprocessor 4 determines air passages adjacent to the finger gap positions as reinforcing air passages according to the contour information, and controls solenoid valves corresponding to the reinforcing air passages to be switched on to a large opening degree and solenoid valves corresponding to remaining air passages to be switched on to a small opening — degree, while solenoid valves corresponding to air passages far from the contours of the two hands can be closed directly. In this way, the two hands are under the joint action of the upper and lower air passages, the air strength and air volume are reinforced at the finger gaps, and the air strength and the air volume are relatively reduced at palms and backs of the hands, thus enabling various parts of the two hands including the finger gaps to be guickly dried, eliminating the hidden positions, and making drying more thorough. In order to adapt to the random movement and placement of the two hands in the intelligent hand dryer, at least 18 groups of upper air passages 15 and lower air passages 34, as well as the corresponding upper straight air outlets 14 and lower straight air outlets 33, thus providing more choices for all fingers and finger gaps. Furthermore, in order to reduce overheat due to excessive air volume — caused by blowing the two hands directly from the upper and lower air passages, the upper straight air outlets 14 and the lower straight air outlets 33 are installed to improve the blowing S softness while achieving the drying effect. N [0025] The intelligent hand dryer provided in the embodiment of this application can ensure uniform drying of two hands without the problem of hidden positions keeping wet or remaining 2 25 positions being too dry, while reducing the waste of electrical energy caused by the opening of a excess air passages and the blowing impact on surrounding environment, thus truly achieving & the intelligent effect of the hand dryer for thorough drying of the two hands at 360° ä all-around.
    [0026] [0026] As an optional embodiment, one end of the head part 1 close to the tail part 3 is in an inclined structure, and one end of the head part 1 close to the backboard 2 is higher than one end 7
    [0027] [0027] In order to adapt to the height of most people, an intelligent hand dryer is usually hung in a high position. In this way, it is relatively difficult for some people, especially children and the elderly, to place their hands horizontally. The most suitable way for a human body to extend and place two hands is to extend the two hands obliguely upwards. Therefore, in order to make a user more comfortable in use, the head part 1 and the tail part 3 are designed as an inclined structure. Furthermore, such a structure can reduce the stay of water drops that are accidentally — dripping onto the lower air baffle 32, and reduce the damage of the water drops to the lower air box 31 and the lower air passages 34. Also, in order to deal with the water drops that slide along the lower air baffle 32, a water absorption strip can be installed at an edge of the lower air baffle
    [0028] [0028] As an optional embodiment, the upper straight air outlets 14 and the lower straight air — outlets 33 are radially arranged; in the upper straight air outlets 14 and the lower straight air outlets 33, the density of air holes close to edges of the upper air baffle 13 and the lower air baffle 32 is greater than the density of air holes away from the edges.
    [0029] [0029] The two hands are composed of fingers and palms. In order to adapt to the shape distribution of fingers and improve the air blowing pertinence of air passages, the upper and — lower air passages are designed as radial shapes corresponding to opening shapes of the fingers. Furthermore, the palms with a large area and more water may correspond to dense air holes to S improve the drying efficiency. N [0030] As an optional embodiment, the hand dryer further comprises a temperature sensor 21; the temperature sensor 21 is arranged on the backboard 2, and the temperature sensor 21 is 2 25 — connected to the microprocessor 4 to detect an environment temperature of an environment in a which the hand dryer is located. & [0031] In order to improve the drying effect of the intelligent hand dryer, a heating device is N installed in the upper air box 11 and the lower air box 31 to increase an air blowing temperature, - by mean of which high temperature and air strength are used for drying. In order to prevent the blowing air from being overheated or undercooled, a temperature sensor 21 is provided on the 8
    [0032] [0032] As an optional embodiment, the hand dryer further comprises an infrared sensor 22 and an ultraviolet lamp 23; both of the infrared sensor 22 and the ultraviolet lamp 23 are arranged on the backboard 2, and the infrared sensor 22 and the ultraviolet lamp 23 are connected to the microprocessor 4.
    [0033] [0033] After the intelligent hand dryer is used for a long time, due to water accumulation, splashing, dust falling and other problems, there will be sanitary problems, causing the drying quality to be greatly reduced. Therefore, the ultraviolet lamp 23 is added to the backboard 2 for sterilization. When the infrared sensor 22 senses that two hands are approaching, the microprocessor 4 controls the ultraviolet lamp 23 to be turned off, avoiding ultraviolet radiation to a human body to cause harm to the human body; when the infrared sensor 22 senses that the IS — two hands are moving away, the microprocessor 4 controls the ultraviolet lamp 23 to be turned on, starting sterilization on the intelligent air blowing hand dryer.
    [0034] [0034] As an optional embodiment, the hand dryer further comprises a timer 24; the timer 24 is arranged on the backboard 2, and the timer 24 is connected to the microprocessor 4.
    [0035] [0035] In order to avoid ultraviolet radiation and waste of electrical energy caused by the ultraviolet lamp 23 being turned on for a long time, the timer 24 is added. The timer 24 detects continuous turned-on time of the ultraviolet lamp 23 and transmits time data to the S microprocessor 4. Once the turned-on time of the ultraviolet lamp 23 reaches a preset N sterilization time, the microprocessor 4 controls the ultraviolet lamp 23 to be turned off. [0036] As an optional embodiment, an upper filter sieve 16 and a lower filter sieve 35 are 2 25 respectively arranged between the upper air baffle 13 and the upper air passages 15, and , between the lower air baffle 32 and the lower air passages 34. & [0037] Due to static electricity, air pressure and other problems, dusts and impurities and the ä like are easy to be accumulated in the upper and lower air passages. When blowing air, the dirt is easy to be blown onto two hands together with the air, increasing hidden health risks. Adding — the upper filter sieve 16 and the lower filter sieve 35 can block the dusts and impurities, thereby 9
