Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 5, the silent drain valve mechanism 10 provided in this embodiment includes a water stop assembly 20, a drain valve, and an inlet cavity 101, an outlet cavity 102 and a back pressure cavity 103 formed in a drain pipe 1, wherein the inlet cavity 101 of the drain pipe 1 is used for connecting a water source, the outlet cavity 102 is used for connecting a toilet flushing pipe, the outlet cavity 102 and the back pressure cavity 103 are isolated by the movable water stop assembly 20, and the water stop assembly 20 moves towards the outlet cavity 102 to isolate the outlet cavity 102 from the inlet cavity 101, as shown in fig. 2; the water stop assembly 20 moves towards the back pressure chamber 103 to connect the water outlet chamber 102 with the water inlet chamber 101, as shown in fig. 3. The back pressure cavity 103 is provided with a water inlet hole 11 communicated with the water inlet cavity 101 and a water outlet 12 for draining water, the water outlet 12 is arranged at the top position of the back pressure cavity 103, and the water outlet valve is used for controlling the draining water of the water outlet 12.

When the water-stopping device is used, the back pressure cavity 103 is controlled to drain water through the drain valve, the pressure is rapidly reduced when the back pressure cavity 103 drains water, and the pressure of the water-stopping component 20 on one side of the back pressure cavity 103 is reduced, so that the water-stopping component 20 moves towards the direction of the back pressure cavity 103 to open a normal flushing channel; after the drain valve is closed, water in the water inlet cavity 101 continuously flows into the back pressure cavity 103, and the water inlet assembly 20 is driven to move towards the water outlet cavity 102, so that the water outlet cavity 102 is isolated from the water inlet cavity 101, and a normal flushing water path is blocked.

The water outlet 12 of the back pressure cavity 103 is arranged at the top of the back pressure cavity 103, so that even if air exists in the back pressure cavity 103 during water drainage, the air is discharged from the water outlet 12 during water drainage, noise is not generated due to mixing of water flow, the silent water drainage of the water drainage valve mechanism 10 is realized, the structure is simple, and the product has market advantages.

Further, in this embodiment, the water stopping assembly 20 includes a flexible sealing film 21 and a fixing plate 22, an outer edge of the flexible sealing film 21 is fixed to an inner wall of the chamber between the water outlet chamber 102 and the back pressure chamber 103 in a sealing manner to isolate the water outlet chamber 102 and the back pressure chamber 103, and the fixing plate 20 is connected to a middle position of the flexible sealing film 21 in a sealing manner to play a role in supporting. The drainage of the back pressure cavity 103 enables the pressure of the water stopping assembly 20 at one side of the back pressure cavity 103 to be rapidly reduced, so that the water stopping assembly 20 moves towards the direction of the back pressure cavity 103 under the action of pressure difference, and the water inlet cavity 101 and the water outlet cavity 102 are communicated in an opening mode; when the back pressure cavity 103 stops draining, water in the water inlet cavity 101 flows into the back pressure cavity 103 through the water inlet hole 11 to be pressurized, so that the water inlet component 20 moves towards the water outlet cavity 102, and then tightly abuts against the through hole between the water outlet cavity 102 and the water inlet cavity 101 again, and the communication between the water outlet cavity 102 and the water inlet cavity 101 is blocked. Of course, in other embodiments, the structure of the water stopping assembly 20 is not limited thereto.

Further, in the present embodiment, the back pressure chamber 103 further includes a drain passage 104 communicating with the drain port 12 of the back pressure chamber 103, and water discharged from the drain port 12 of the back pressure chamber 103 flows out through the drain passage 104, and the drain valve is provided in the drain passage 104 to control on/off of the drain passage 104, thereby controlling drainage of the drain port 12. The drain passage 104 is provided, so that air in the back pressure chamber 103 can be discharged from the drain port 12 of the back pressure chamber 103 to the drain passage 104 in advance, and the air discharged to the drain passage 104 can be discharged in time without causing noise without being accumulated in the back pressure chamber 103. Simultaneously, because of backpressure chamber 103 is small, still need cooperate with intake antrum 101, play water cavity 102 etc., the position of arranging at will is unable, extend the drainage route, the arrangement of accessible drainage route 104, arrange drainage route 104 in suitable position, like drainage valve mechanism 10's top position, then set up the drain valve, make the drain valve be located the position of convenient operation, the overall arrangement of very big simplified drainage valve mechanism 10, the overall arrangement position that makes backpressure chamber 103 can save the consideration of the position of arranging of drain valve (especially manual drain valve). Of course, in other embodiments, such as just providing an electronic valve, the structure of the drain passage may be omitted.

Still further, in this embodiment, the drain valve is manual drain valve, includes: the drainage passage 104 is provided with a drainage hole 1041, the connecting shaft 32 is arranged in the drainage hole 1041 in a penetrating manner, the sealing block 33 is arranged on the connecting shaft 32 and corresponds to the drainage hole 1041, the return spring 34 applies a force to the connecting shaft 32 to enable the sealing block 33 on the connecting shaft 32 to move towards the drainage hole 1041 and seal the drainage hole 1041, namely, the return spring 34 drives the connecting shaft 32 and the sealing block 33 to move simultaneously, the moving direction is the direction of the sealing block 33 towards the drainage hole 1041, the sealing block 33 seals the drainage hole 1041, and the drainage passage 104 is blocked. The manual button 31 is connected to the connecting shaft 32, the pressing of the manual button 31 drives the connecting shaft 32 to overcome the acting force of the return spring 34 and the water pressure applied to the sealing block 33 (i.e., the water pressure applied to the sealing block 33 by the water in the back pressure chamber 103 and the drainage passage 104) so that the sealing block 33 on the connecting shaft 32 moves in the direction of separating from the drainage hole 1041, i.e., the pressing of the manual button 31 drives the connecting shaft 32 and the sealing block 33 to move simultaneously, and the moving direction is the direction in which the sealing block 33 separates from the drainage hole 1041, so that the sealing block 33 separates from the drainage hole 1041, and the drainage passage 104 is conducted. Of course, in other embodiments, the structure of the manual drain valve may adopt other existing structures; alternatively, the drain valve may be configured not to use the drain passage 104, and the on/off of the drain port 12 may be controlled in direct correspondence with the drain port 12.

Furthermore, in this embodiment, the drainage channel 104 is connected to the water outlet cavity 102, so as to drain the water in the back pressure cavity 103 into the water outlet cavity 102, without adding additional drainage pipes, and at the same time, fully utilize water resources.

Furthermore, in this embodiment, the back pressure chamber 103 is communicated with the water inlet chamber 101 through the water inlet hole 11, and the water inlet hole 11 is provided with the needle 111 for limiting the flow in a penetrating manner, so that the function of limiting the flow can be effectively achieved, which is equivalent to a needle valve structure. Of course, in other embodiments, the invention is not limited thereto.

Still further, the needle 111 penetrating the water inlet 11 is fixed by a spring 112 disposed in the back pressure chamber 103, that is, the needle 111 is formed by extending one end of the spring 112. Still further, the spring 112 only plays a role of positioning, and the arrangement of the spring 112 has a negligible influence on the action of the water stop assembly 20.
