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.
As shown in fig. 1 to 4, the embodiment provides a water inlet valve with an ejector, an ejector 20 is installed on a water outlet end of the water inlet valve, and the water outlet end of the ejector 20 is used for being connected with a brush ring pipe on a toilet bowl body, so that the wall of a toilet bowl can be cleaned.
Specifically, the injector 20 includes an injection pipe 201 and a mixing pipe 202, the water inlet end of the injection pipe 201 is used for connecting with the water outlet end of the water inlet valve, and the water outlet end of the injection pipe 201 has a nozzle 2010; the water inlet end of the mixing tube 202 is provided with a drainage port 2020 facing the nozzle 2010, and the water outlet end of the mixing tube 202 is connected with the water inlet end of the brush ring tube; the aperture of the drainage port 2020 is larger than that of the jet hole 2011 of the nozzle 2010, and a gap 203 communicated with the water tank is formed between the drainage port 2020 and the nozzle 2010.
When water flows out from the nozzle 2010 of the injection pipe 201, because the aperture of the injection hole 2011 is small, the flow rate is increased sharply, negative pressure is formed around the nozzle 2010, and the water around is sucked into the mixing pipe 202 of the ejector together, so that the water spraying amount entering the brush ring pipe is increased, and the flushing effect on the peripheral wall of the toilet bowl is improved.
In the present embodiment, the injection pipe 201 and the mixing pipe 202 are integrally formed as a single piece through an injection molding process to facilitate the installation of the injector 20.
In this embodiment, the drainage port 2020 of the mixing tube 202 is of a bell-mouth structure gradually reduced from the water inlet end to the water outlet end, so that the drainage port 2020 can drain more water around into the mixing tube 202, thereby improving the flushing effect on the peripheral wall of the toilet bowl.
In this embodiment, the water inlet valve is a pneumatic control water valve, and includes a valve body 10, a water stopping assembly 11 and a pneumatic control assembly 12, which are installed in the valve body 10, and the pneumatic control assembly 12 and the water stopping assembly 11 are arranged in a linkage manner to open the water inlet valve.
Specifically, a water inlet 101, a water outlet 102 and a back pressure cavity 103 are arranged in the valve body 10, the back pressure cavity 103 is a cavity with one end open and the other end closed, the water stopping component 11 is arranged at the open end of the back pressure cavity 103, and the pneumatic control component 12 is arranged at the closed end of the back pressure cavity 103.
In this embodiment, an outlet pipe 104 connected to the brush ring pipe extends from the water inlet 101 of the valve body 10 into the valve body 10, a gap is formed between the outer wall of the outlet pipe 104 and the inner wall of the valve body 10, and water can flow through the gap and flow out of the outlet pipe 104. The design is not only beneficial to the realization of the opening and closing of the water inlet valve by the rear water stopping assembly 11, but also shortens the water passing stroke between the water inlet 101 and the water outlet 102 in the water inlet valve, and can reduce the response time during flushing.
The water stopping assembly 11 comprises a valve core 111 capable of moving in the valve body 10, a first return spring 112 for applying a return elastic force to the valve core 111, and a first sealing member 113 capable of blocking the water inlet of the water outlet pipe 104, wherein the head of the valve core 111 is provided with a guide part 114 extending into the water outlet pipe 104, and the guide part and the water outlet pipe 104 are matched with each other to guide the movement of the valve core 111; the bottom of the valve core 111 is provided with a piston part 115 which can be in movable sealing contact with the back pressure cavity 103 so that one end of the back pressure cavity 103 can be blocked by the valve core 111, and the valve core 111 is provided with a water through hole 116 which is communicated with the back pressure cavity 103 and the water inlet 101. The first seal member 113 is fixedly mounted on the valve element 111 and has a seal portion in sealing contact with the end surface of the outlet pipe 104.
The pneumatic control assembly 12 includes a telescopic air bag 121, a pressure relief head 122 disposed in cooperation with the air bag 121, and a second return spring 123 for applying a return elastic force to the pressure relief head 122. The closed end of the back pressure cavity 103 is provided with a pressure relief hole 105, the pressure relief head 122 is provided with a blocking section extending from the pressure relief hole 105 to the inside of the back pressure cavity 103, and the blocking section is fixedly provided with a second sealing element 120 matched with the pressure relief hole 105.
The air bag 121 is connected to the air inlet pipe, when the air inlet pipe is not used for air transmission, the second sealing element 120 on the pressure relief head 122 seals the pressure relief hole 105 under the elastic force of the second return spring 123, external water flows into the back pressure cavity 103 from the water through hole 116, so that the back pressure cavity 103 maintains a high water pressure, and meanwhile, the valve core 111 seals the water outlet pipe 104 under the action of the first return spring 112, that is, the water inlet valve is in a closed state.
When the air inlet pipe begins to convey air, the air bag 121 extends out by the air, so that the second sealing element 120 on the pressure relief head 122 is separated from the pressure relief hole 105 and opened, the water pressure in the back pressure cavity 103 is rapidly reduced, the valve core 111 is pushed open by the larger water pressure, the first sealing element 113 on the valve core 111 is not in sealing contact with the water outlet pipe 104, water rapidly flows from the water inlet 101 to the water outlet 102, and is finally discharged from the brush ring pipe to wash and fall the peripheral wall of the urinal.
