    BACKGROUND [0002] The water temperature setting function of the conventional pressure-type temperature-controlled switching valve is provided by a ceramic moving part and a ceramic static part. Inlets of cold water and hot water are provided in the ceramic static part, while a water mixing chamber is arranged inside the ceramic moving part, and when the cold water and hot water are introduced into the water mixing chamber, the water discharge function has been performed by opening or closing the pressure switching component. However, the previously described pressure type temperature-controlled switching valve suffers from a few defects: there is a high requirement for the flat shape of the ceramic moving part and the ceramic static part while adopting the ceramic moving part and the ceramic static part to perform the temperature control function, otherwise water leakage can easily occur, particularly in the switching valve structure used to reduce the pressure force. A pressure balancing mechanism is required in the switching valve structure to reduce the pressure force, and an instantaneous high pressure is produced during the opening and closing process which readily separates the ceramic moving part used to mix cold water and hot water, resulting in leakage of the entire switching valve. In addition, because the pressure balancing mechanism is adopted in the switching valve, if the water mixing chamber is depressurized, other structures will be influenced and will fail at the same time, leading to decommissioning. of the entire structure. In addition, the sealing part of the drive pressure structure of the existing pressure switching valve is easily deformed, particularly due to the pressure coming from the side, so that the sealing piece can not achieve sealing effectively and thus the service life of the switching valve will be influenced.

    The embodiment of this utility model discloses a pressure type temperature controlled switching valve, including a housing 1, a valve seat 3, a ratchet seat 411, a ratchet push rod. 412, an inner rotatable rod 413, a connecting rod 42, a second spring 43, a third spring 44, a pressure-supporting inner cover 51, an inner valve core seat 52, a first spring 53, a film-forming member water-tight sealing element 54, a ceramic moving part 61 and a ceramic static part 62.
    By assembling the temperature adjusting component 6, the ceramic static part 62 is fixedly mounted on the valve seat 3 and the ceramic moving part 61 is connected to the valve core inner seat 52 by a fastener. and is rotated by the valve core inner seat 52. After that, the valve core inner seat 52 is engaged and is connected to the ratchet seat 411.
    By assembling the water seal mechanism before pressure 5, firstly the spring 53 is loaded into the inner cover supporting the pressure 51. The piece forming water-tight film 54 is mounted to the inside the pressure-supporting inner cover 51 and pressed against it by the first spring 53 to seal the partition wall portion 520 in the valve core inner seat 52 and is then integrally connected to the inner seat of valve core 52.
    By assembling the control component 4, firstly the flexible sealing rubber 8 is mounted on the connecting rod 42 and placed in the end of the connecting rod 42. The second spring 43 is sleeved in the rotary rod 413, and the connecting rod 42 is engaged and connected to one end of the inner rotary rod 413, so that the connecting rod 42 is moved synchronously with the displacement of the inner rotary rod 413.

The cold water and hot water from the cold water inlet 621 and the hot water inlet 622 of the ceramic static part 62 enter the water mixing chamber 612 through of the ceramic moving part 61. While the ceramic moving part 61 is rotated, the watertight portion 611 on the latter is linked to move in order to completely or partially block one or the other. Other water inlets 621, 622. The hydraulic pressure of the water mixing chamber 612 acts on the ceramic moving part 61, so that the ceramic moving part 61 is hard to repel by the mixed water .
    While the pressure implementation end of the ratchet push rod 412 is squeezed, the pressing force of the ratchet push rod 412 pushes the inner rotatable rod 413 and the connecting rod 42 to move downwardly while overcoming the spring force of the third spring 44, and cause the flexible sealing rubber 8 of the connecting rod 42 to move downwardly to seal the pressure relief hole 540 of the forming piece When the pressure force is removed, the moving ratchet 412B of the ratchet push rod 412 bounces under the force of the second spring 43 and the inner rotatable rod 413 is rotated to a certain position. which causes the ratchet portion 413A thereon to engage and engage the limiting portion 411A. At this time, the pressure relief hole 540 is still sealed by the flexible sealing rubber 8 of the connecting rod 42. The water in the water mixing chamber 612 flows into the hydraulic chamber 50 through the connecting channel 55 and occupies the entire hydraulic chamber 50. The water in the hydraulic chamber 50 pushes the water-sealing film piece 54 down against the partition wall portion 520 of the inner seat of the Valve Core 52. Since the water outlet 60 is in communication with the atmosphere and the pressure is zero, the water-sealing film piece 54 is pressed against the partition wall portion. 520 without deformation, so that the water in the water mixing chamber 612 can not pass through the partition wall portion 520 and enter the water outlet 60.
    As shown in FIG. 6, when the pressure implementation end of the ratchet push rod 412 is pressed again, the inner rotary rod 413 is urged to move by the ratchet push rod. 412 under the pressure force. When the pressure force is removed, under the force of the second spring 43, the ratchet portion 413A is detached from the limiting portion 411A and the pressure on the inner rotatable rod 413 disappears resulting in the flexible sealing rubber 8 with the connecting rod 42 to move upwardly and in turn maintains the open pressure relief hole 540, and thus the water is discharged to the water outlet 60 through the pressure relief hole 540, so that the pressure of the hydraulic chamber 50 immediately becomes unbalanced. The pressure of the hydraulic chamber 50 is less than the pressure of the water mixing chamber 612, and thus the water-sealing film piece 54 is pushed open, so that a large amount of water from the water mixing chamber 612 is discharged from the water outlet 60 to form a water flow.
    The present utility model proposes a pressure-type switching valve of pressure type, which is simple in structure and easy to achieve. The mixing chamber formed by the ceramic moving part and the ceramic static part of the temperature adjusting component extends to the entire valve body, so that the ceramic moving part and the ceramic static part are pressed. by the hydraulic pressure of the water mixing chamber to provide pressure compensation. As a result, the ceramic moving part is hard to repel by the impacts during the mixing of water and the failure of the temperature adjustments caused by the latter is prevented and the space of the water mixing chamber is enlarged at the same time. time. In addition, the hydraulic chamber is opened or closed by the connecting rod, so that the switching can be performed with only a small implementation force and the required pressure implementation force is thus reduced. The support piece is provided on the sealing film part of the present utility model to ensure better engagement between the sealing film member and the partition wall portion and thus a better sealing effect. . The flexible sealing rubber is provided on the connecting rod of this utility model to seal the pressure relief hole, so that the sealing effect is better and a water leak can be effectively prevented. . In addition, the connecting rod is made of rigid plastic or metal, so that the side of the flexible sealing rubber is hard to deform to avoid a seal failure. The control component adopted in this utility model lengthens the pressure process, so not only is the pressure force reduced, but also the open state or the closed state can be determined visually and the pressure process can to be felt by touch. The components inside the switching valve would not be damaged or broken due to too much force and these components are protected and their service life is prolonged.
