Description

Technical Field

[0001] The utility model relates to the technical field of bathroom structures, in particular to an air-blocking water inlet valve with a water-stop cup. Background Art

[0002] The existing air water inlet valve structure includes a vertically arranged water inlet pipe, a back pressure switch for opening or closing the waterway, and a float. The float is connected to the back pressure switch in a transmission manner to drive the back pressure switch to open or close. The float is arranged in the water stop cup. After the water in the water tank reaches a certain height, the water flows into the water stop cup, causing the float in the water stop cup to rise and then drive the back pressure switch through the connecting rod to close the water inlet channel. When the user operates the pressure relief, the water in the water stop cup flows out to cause the float to drop, thereby opening the water inlet switch for water replenishment. In the existing air water inlet valve, the pressure relief water flow of the valve body and the splashing water drops from the water outlet are easy to fall into the water stop cup, causing the water in the water stop cup to rise in advance, thereby causing the water in the water stop cup to stop water in advance, resulting in insufficient water level in the water tank. Utility Model Content

[0003] The utility model discloses an air-blocking water inlet valve with a water-stopping cup, aiming to solve the above-mentioned problems.

[0004] The utility model adopts the following scheme:

[0005] The present application provides an air-blocking water inlet valve with a water stop cup, comprising a valve body, a water stop assembly, an adjusting rod assembly, a float, and a water stop cup, wherein the float is arranged in the water stop cup, the valve body is connected to the water stop assembly, and the water stop assembly is connected to the float through the adjusting rod assembly so as to close the valve body when the float rises and open the valve body when the float descends, a retaining ring is formed on the top of the float, at least one water leakage port is arranged on the retaining ring, and an avoidance position corresponding to the water leakage port is arranged on the water stop cup so as to facilitate the timely discharge of water in the retaining ring, thereby preventing the water flow from entering the water stop cup in advance.

[0006] Furthermore, a water outlet is provided on the valve body, and the retaining ring is provided below the valve body to collect the pressure relief water flow of the valve body and the splashing water droplets from the water outlet.

[0007] Furthermore, the water stop cup and the float are provided with guide grooves in the vertical direction, and the guide grooves are suitable for placing guide tubes.

[0008] Furthermore, the guide pipe is arranged below the water outlet to receive the water flowing out of the water outlet, thereby reducing the noise of falling water.

[0009] Furthermore, the avoidance position and the guide groove are arranged separately.

[0010] Furthermore, the float is provided with a groove below the water leakage port which matches the avoidance position on the water stop cup.

[0011] Furthermore, the guide groove is arranged on a side surface adjacent to the groove.

[0012] Furthermore, the water leakage opening is a notch arranged on the enclosure ring.

[0013] Beneficial effects:

[0014] This solution sets a retaining ring on the top surface of the float to collect the pressure relief water flow of the valve body and the splashing water drops from the water outlet, and sets a water leakage port on the retaining ring to discharge the collected water in time, and sets an avoidance position on the water stop cup so that the water flowing out of the water leakage port can directly flow out from the outside of the water stop cup, preventing the pressure relief water flow of the valve body and the splashing water drops from the water outlet from directly falling into the water stop cup, causing the float to rise in advance and close the water inlet of the valve body. At the same time, this design can reduce the space occupancy rate of the water inlet valve, and the cross-sectional area of ​​the water stop float of the water inlet valve can be kept unchanged by using this structure, effectively avoiding the abnormality of the water inlet valve stopping water in advance.

[0020] Combination Figures 1 to 4As shown, the present embodiment provides an air-blocking water inlet valve with a water-stop cup, comprising a valve body 1, a water-stop assembly 2, an adjusting rod assembly 3, a float 4, and a water-stop cup 5, wherein the float 4 is arranged in the water-stop cup 5, the valve body 1 is connected to the water-stop assembly 2, and the water-stop assembly 2 is connected to the float 4 through the adjusting rod assembly 3, so that the valve body 1 is closed when the float 4 rises, and the valve body 1 is opened when the float 4 descends, a retaining ring 41 is formed on the top of the float 4, at least one water leakage port 42 is arranged on the retaining ring 41, and an avoidance position 52 corresponding to the water leakage port 42 is arranged on the water-stop cup 5 to facilitate the timely discharge of water in the retaining ring 41, thereby preventing the water flow from entering the water-stop cup 5 in advance.

[0021] In this embodiment, the air inlet valve is suitable for installation in a water tank to control the water inlet and outlet of the water tank. The valve body 1, the regulating rod assembly 3 and the water stop assembly 2 are all prior art and will not be elaborated here. The float 4 is arranged in the water stop cup 5. The water stop cup 5 can enter the water after the water level in the water tank reaches a certain height, so that the float 4 rises. When the float 4 rises, it will drive the regulating rod assembly 3 to rise synchronously, and then drive the water stop assembly 2 connected to the regulating rod assembly 3 to close the water inlet channel of the valve body 1. On the contrary, when the user operates to release the pressure, the water level of the water tank drops, and the water in the water stop cup 5 flows out, causing the float 4 to drop and drive the water stop assembly 2 to open the water inlet channel of the valve body 1 for water replenishment.

[0022] Combination Figures 1 to 4As shown, the shape of the float 4 is similar to that of the water stop cup 5. The float 4 and the water stop cup 5 are provided with mounting holes for installing the adjusting rod assembly 3. The float 4 can move in the water stop cup 5, so as to rise under the action of buoyancy. Specifically, a retaining ring 41 is provided on the top edge of the float 4, and a leaking port 42 is provided on the retaining ring 41 for draining the water in the retaining ring 41. Here, the leaking port 42 can be a notch provided on the retaining ring 41. Here, the retaining ring 41 is provided below the water outlet 11 of the valve body 1, and can be used to collect the pressure relief water flow of the valve body 1 and the splashing water droplets of the water outlet 11, so as to prevent the pressure relief water flow and the splashing water droplets of the water outlet 11 from directly falling into the water stop cup 5 and causing the float 4 to rise prematurely. An inwardly recessed avoidance position 52 is provided on the water stop cup 5 at the position of the leaking port 42. A groove 43 matching the avoidance position 52 on the water stop cup 5 is provided below the water leakage port 42 of the float 4. Here, the recessed space of the avoidance position 52 is located below the water leakage port 42, so that the water flowing out of the water leakage port 42 can flow down into the water tank along the outside of the recessed space of the avoidance position 52, and will not flow directly into the water stop cup 5. In a preferred embodiment, the enclosure ring 41 is tilted outward to block the gap above the water stop cup 5 and the float 4, thereby improving the water collection effect of the enclosure ring 41.

[0023] In one embodiment, the water stop cup 5 and the float 4 are provided with a guide groove 51 in the vertical direction, and the guide groove 51 is suitable for placing the guide pipe 6. Here, the guide pipe 6 is arranged below the water outlet 11 to receive the water flow from the water outlet 11, thereby reducing the noise of the falling water flow. In this embodiment, the avoidance position 52 is arranged separately from the guide groove 51, so that the structure is more compact and reasonable. Specifically, the guide groove 51 is arranged on the side adjacent to the groove 43 to make the structure compact.

[0024] Through this embodiment, the design can reduce the space occupancy rate of the water inlet valve. By utilizing this structure, the abnormal situation of the water inlet valve stopping water in advance can be effectively avoided without increasing the cross-sectional area of ​​the water inlet valve water-stopping float 4, which is particularly suitable for applications in narrow water tanks.

[0025] It should be understood that the above are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.

[0026] The above description of the drawings used in the implementation manner only shows certain embodiments of the utility model and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying creative work.
