[0002] High-pressure resistant faucets are a common name for water valves used to control the flow of water. They have water-saving effects. Faucets are being updated very quickly, from old-fashioned cast iron to electroplated knob faucets, and then to stainless steel single-temperature single-control faucets, stainless steel dual-temperature dual-control faucets, and semi-automatic kitchen faucets.

[0003] In order to prevent the water outlet of the faucet from becoming clogged and to achieve preliminary filtration of the water, a filter screen is usually installed inside the main body of the faucet to achieve a filtration effect. However, after the valve is closed, the filter screen is also immersed in water for a long time, which will accelerate the corrosion rate of the filter screen and reduce its service life.

[0022] Example 1

[0023] like Figures 1-6 As shown, the high-pressure resistant faucet and components proposed in this embodiment include a main housing 1, a valve body housing 5, and a power component.

[0024] The two ends of the main housing 1 are respectively connected to the nozzle 3 and the water inlet pipe 4; the nozzle 3 is equipped with an infrared sensor, and the main housing 1 is equipped with a controller. When the infrared sensor detects a hand blocking the nozzle 3, it sends a signal to the controller, which then controls the servo motor to start working, so that the valve is in the open state. When the hand moves away from the infrared sensor, the valve is in the closed state, thus realizing the function of automatically opening the valve.

[0025] The valve body housing 5 is located at the upper end of the main housing 1. The valve body housing 5 has a first movable cavity 501 and a second movable cavity 502. A sealing frame 9 is slidably mounted on the inner side of both the first movable cavity 501 and the second movable cavity 502. A sealing assembly is provided on the sealing frame 9. The sealing assembly includes a first sealing gasket 111, a first rectangular sealing strip 112, a second sealing gasket 113, and a second rectangular sealing strip 114. The first sealing gasket 111 is located at the bottom end of the sealing frame 9, and the first rectangular sealing strip 112 is located on the side of the sealing frame 9. The first sealing gasket 111, the first rectangular sealing strip 112, the second sealing gasket 113, and the second rectangular sealing strip 114 are arranged at the lower part of the gate plate 8. The second rectangular sealing strip 114 is arranged around the sealing outer frame 9 and is arranged horizontally. The first sealing gasket 111, the first rectangular sealing strip 112, the second sealing gasket 113, and the second rectangular sealing strip 114 are used to improve the sealing performance between the sealing outer frame 9 and the main housing 1, and between the sealing outer frame 9 and the valve body housing 5. The gate plate 8 and the filter screen are respectively installed on the inner side of the two sealing outer frames 9.

[0026] A power assembly is installed on the valve body housing 5 to drive the two sealing frames 9 to move in opposite directions. The power assembly includes a servo motor, a gear 13, and two racks 14. A first mounting cavity 503 is provided on the valve body housing 5. The gear 13 is rotatably mounted on the inner side of the first mounting cavity 503. Both racks 14 mesh with the gear 13. Two sliding holes are also provided on the valve body housing 5. The first movable cavity 501 and the second movable cavity 502 are respectively connected to the first mounting cavity 503 through the sliding holes on both sides. A second connecting slider is connected to each of the two racks 14. The two second connecting sliders are respectively connected to the sealing frames 9 on both sides.

[0027] It also includes a sealing plate 6, with a third rectangular sealing strip 115 disposed around its periphery. A lever 12 is disposed at the bottom of the outer side of the sealing plate 6. A cleaning hole 504 communicating with the second movable cavity 502 is provided on the valve body shell 5. The main body of the third rectangular sealing strip 115 is movably disposed inside the cleaning hole 504, and its upper part movably penetrates the top of the valve body shell 5. An elastic reset assembly is connected to the sealing plate 6. A second mounting cavity 505 communicating with the cleaning hole 504 is provided on the valve body shell 5. The elastic reset assembly includes a first connecting slider 15 and a guide. Rod 16 and spring 17, first connecting slider 15 connected to sealing plate 6, guide rod 16 set inside second mounting cavity 505, first connecting slider 15 slidably set on guide rod 16, spring 17 sleeved on guide rod 16; move sealing plate 6 upward so that cleaning hole 504 is completely exposed, at this time impurities on the surface of filter screen can be cleaned through cleaning hole 504. After cleaning is completed, release sealing plate 6, under the elastic force of elastic reset component drive sealing plate 6 to automatically reset, realizing automatic sealing of cleaning hole 504.

[0028] Specifically, during the upward movement of the drive gate 8, the filter screen moves downward under the transmission action of the gear 13 and rack 14. When the gate 8 moves to the upper limit position, the filter screen moves downward to the limit position. At this time, the valve is in the open state, and the filter screen is placed inside the main housing 1. The filter screen installed inside the main housing 1 can filter the incoming water to reduce impurities in the water. After the drive gate 8 moves to the lower limit position, the valve is in the closed state, and the filter screen is completely moved inside the second active chamber 502. This can prevent the filter screen from being soaked in water for a long time, thereby extending the service life of the filter screen.

[0029] It should be noted that the main housing 1, nozzle 3, water inlet pipe 4, and valve body housing 5 are all made of lead-free brass, which has high strength and good high pressure resistance.

[0030] Example 2

[0031] like Figure 3As shown, the high-pressure resistant faucet and components proposed in this embodiment, compared with Embodiment 1, have two sealing bases 10 installed on the inner bottom of the main housing 1. The upper cross-section of the sealing base 10 is triangular, and the bottom end of the first sealing gasket 111 fits with the upper end of the sealing base 10. By setting the pointed structure on the upper end of the sealing base 10, impurities inside the main housing 1 are less likely to accumulate on the sealing base 10, which improves the sealing performance between the bottom end of the sealing frame 9 and the sealing base 10. At the same time, the pointed structure on the upper end of the sealing base 10 can increase its contact area with the first sealing gasket 111, further enhancing the sealing effect between the bottom end of the sealing frame 9 and the sealing base 10.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
