Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a water inlet valve and a toilet. Background Art

[0002] In existing toilet water inlet valves, the inlet valve stem is typically mounted on the float lever using a snap-fit ​​connection. This connection makes the inlet valve stem susceptible to side-to-side wobble or displacement, making it difficult to accurately transmit the water level sensed by the buoyancy mechanism to the valve assembly, thus affecting the stability of the valve assembly. Due to the wobble, displacement, and instability of the inlet valve stem, the pressure relief hole in the valve assembly cannot be effectively sealed, and the valve assembly cannot be effectively triggered, affecting the accuracy of water inlet control. Consequently, even when the water tank is full, water continues to flow into the valve assembly, causing the tank to overflow. Utility Model Content

[0008] A back pressure cavity is formed between the water control member and the valve cover, and a pressure relief hole is provided on the valve cover, through which the back pressure cavity is communicated with the outside world;

[0009] The water inlet control mechanism includes a water level sensing mechanism and an opening and closing hole mechanism. The water level sensing mechanism is used to detect the water level, and the opening and closing hole mechanism is used to open or close the pressure relief hole according to the detection result of the water level sensing mechanism; the water level sensing mechanism and the opening and closing hole mechanism are connected, and the valve seat is provided with a pressure relief channel connected to the pressure relief hole, and the opening and closing hole mechanism is arranged in the pressure relief channel to open or close the pressure relief hole.

[0010] As an improvement to the above solution, the valve seat is provided with a mounting seat, the mounting seat is provided with a mounting cavity, and the opening and closing hole mechanism is installed in the mounting cavity.

[0011] As an improvement to the above solution, a first through hole communicating with the mounting cavity is provided on the mounting seat, and the first through hole is communicated with the pressure relief hole through a conducting pipe.

[0012] As an improvement to the above solution, a flushing hole and a second through hole are provided on the valve seat, the flushing hole is connected to the outside, and the flushing hole, the second through hole and the installation cavity are connected in sequence;

Therefore, the utility model can accurately sense the water level height and effectively close the pressure relief hole through the cooperation of the water level sensing mechanism and the opening and closing hole mechanism, thereby improving the accuracy of water inlet control and having a simple structure.

[0029] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0030] See also Figure 1-5 The utility model discloses a water inlet valve, comprising a valve group mechanism and a water inlet control mechanism.

[0031] The valve group mechanism includes a valve seat 2, a valve cover 3 and a water control member 4 provided on the valve seat 2. The water control member 4 is made of elastic material. The valve cover 3, the water control member 4 and the valve seat 2 are connected in sequence.

[0032] A water outlet cavity 22 is formed between the water control member 4 and the valve seat 2 , and a water pipe 21 is provided in the water outlet cavity 22 . The water control member 4 and the water pipe 21 are in contact with or separated from each other, so that the water pipe 21 is disconnected from or connected to the water outlet cavity 22 .

[0033] A back pressure chamber 32 is formed between the water control member 4 and the valve cover 3 . A pressure relief hole 31 is provided on the valve cover 3 . The back pressure chamber 32 is communicated with the outside through the pressure relief hole 31 .

[0034] The water inlet control mechanism is used to control the opening or closing of the pressure relief hole 31 according to the change of water level.

[0035] The water inlet control mechanism includes a water level sensing mechanism 6 and an opening and closing hole mechanism 7. The water level sensing mechanism 6 is used to detect the water level, and the opening and closing hole mechanism 7 is used to open or close the pressure relief hole 31 according to the detection result of the water level sensing mechanism 6; the water level sensing mechanism 6 and the opening and closing hole mechanism 7 are connected, and a pressure relief channel connected to the pressure relief hole 31 is provided on the valve seat 2, and the opening and closing hole mechanism 7 is arranged in the pressure relief channel to open or close the pressure relief hole 31.

[0036] The utility model provides a water inlet valve with a water inlet control mechanism, which includes a water level sensing mechanism and an opening and closing hole mechanism. The water level sensing mechanism is used to detect changes in the water level in the toilet water tank, and the opening and closing hole mechanism is arranged in the pressure relief channel. The opening and closing hole mechanism is opened or closed according to the detection result of the water level sensing mechanism, so that the pressure relief channel is connected or interrupted, thereby opening or closing the pressure collecting hole. When water enters the water tank, the opening and closing hole mechanism is in an open state, so that the pressure relief hole, i.e., the back pressure chamber, is connected to the outside world. At this time, the water control part is pushed open under the action of water pressure, so that water flows into the water outlet chamber, thereby replenishing water to the water tank. When the water level sensing mechanism detects that the water level in the water tank is lower than the preset height, it will send a signal to close the opening and closing hole mechanism, so that the pressure relief hole, i.e., the back pressure chamber, is not connected to the outside world, causing the water control part to reset, re-close the water pipe, interrupt the water pipe and the water outlet chamber, and stop water inlet. Therefore, the utility model can accurately sense the water level height and effectively close the pressure relief hole through the cooperation of the water level sensing mechanism and the opening and closing hole mechanism, thereby improving the accuracy of water inlet control and having a simple structure.

[0037] Preferably, the water level sensing mechanism 6 is a float switch, and the opening / closing mechanism 7 is a solenoid valve. The float switch utilizes a magnetic float on the switch that rises or falls with the liquid level, actuating a reed switch chip at a predetermined position within the switch's detection tube, generating a contact open / close switching signal. A solenoid valve is an industrial device controlled by electromagnetics and serves as a fundamental automation component for fluid control. Both the float switch and the solenoid valve utilize existing technical structures and will not be described in detail here.

[0038] Specifically, such as Figure 1 、 3As shown in Figure 5, the valve seat 2 is provided with a mounting seat 8, which defines a mounting cavity 81. The opening and closing hole mechanism 7 is installed in the mounting cavity 81. More specifically, the mounting seat 8 is provided on the outer wall of the valve seat 2. The valve seat 2 and the mounting seat 8 are integrally formed. The opening and closing hole mechanism 7 is provided on the outer wall of the valve seat 2 via the mounting seat 8.

[0039] Preferably, if Figure 5 As shown, the mounting base 8 is provided with a first through-hole 82 that communicates with the mounting cavity 81. This first through-hole 82 communicates with the pressure relief hole 31 via the conducting tube 5. Specifically, one end of the conducting tube 5 communicates with the pressure relief hole 31, and the other end communicates with the first through-hole 82. The provision of the first through-hole establishes communication between the conducting tube and the opening and closing mechanism within the mounting base.

[0040] Further, if Figure 3 、 5 As shown, the valve seat 2 is provided with a flushing hole 24 and a second through-hole 25. The flushing hole 24 is connected to the outside world. The flushing hole 24, the second through-hole 25, and the installation cavity 81 are sequentially connected. The flushing hole 24, the second through-hole 25, the installation cavity 81, the first through-hole 82, and the conducting tube 5 form a pressure relief passage. In other words, the flushing hole 24, the second through-hole 25, the installation cavity 81, the first through-hole 82, the conducting tube 5, and the pressure relief hole 31 are sequentially connected. Ultimately, the pressure relief hole is connected to the outside world through the flushing hole, allowing the pressure relief hole to be opened and water to be replenished in the water tank. The opening and closing hole mechanism opens or closes within the pressure relief passage, causing the pressure relief hole to open or close.

[0041] Among them, such as Figure 4-5 As shown, the first valve tube 71 of the opening and closing hole mechanism 7 is inserted into the first through hole 82, and the second valve tube 72 of the opening and closing hole mechanism 7 is inserted into the second through hole 25; the first through hole 82 and the second through hole 25 are connected or interrupted by the opening and closing hole mechanism 7. Therefore, the communication between the first through hole and the second through hole needs to pass through the opening and closing hole mechanism. When the opening and closing hole mechanism is open, the first through hole and the second through hole are connected, so that the pressure relief hole is opened; when the opening and closing hole mechanism is closed, the first through hole and the second through hole are not connected, so that the pressure relief hole is closed, so that the pressure relief hole can be effectively closed by the opening and closing hole mechanism, avoiding the water inlet valve stem from shaking or displacement and failing to effectively close the pressure relief hole, thereby preventing the water tank from overflowing and improving the accuracy of water inlet control.

[0042] In addition, if Figure 1-2 As shown, the valve assembly mechanism further includes a valve housing 1, the valve seat 2 is provided on the top of the valve housing 1, and a water inlet channel 11 is provided in the valve housing 1. The water inlet channel 11 is connected to the water pipe 21. The water source is connected to the water inlet channel, and water flows into the water pipe through the water inlet channel.

[0043] Specifically, such as Figure 1 、 4As shown in Figure 5, the water inlet control mechanism also includes a main control board 9 and a power supply 10. The main control board 9 is connected to the water level sensing mechanism 6, the opening and closing hole mechanism 7, and the power supply 10, respectively. The power supply 10 is preferably a lithium battery. The power supply supplies power to the water level sensing mechanism, the opening and closing hole mechanism, and the main control board.

[0044] Going further, Figure 1-2 As shown in Figures 4 and 5, the present invention further includes a hydroelectric generating mechanism 12 connected to the main control board 9. The hydroelectric generating mechanism 12 is preferably a hydroelectric generator. The valve seat 2 is provided with a water outlet 23 that communicates with the water outlet chamber 22. The hydroelectric generator 12 is mounted on the valve seat 2 and extends into the water outlet 23. Water in the water outlet chamber 22 flows into the water outlet 23 and then into the water tank through the water outlet 23.

[0045] When water flows through the outlet, the water flow will drive the hydroelectric blades on the hydroelectric generator to rotate. The hydroelectric generator converts mechanical energy into electrical energy and stores it in the lithium battery to supply power to the water level sensing mechanism, opening and closing hole mechanism and main control board, which is efficient and energy-saving, environmentally friendly and low-cost.

[0046] During water intake, water flows from the water inlet channel 11 to the water pipe 21. As the water level drops after draining, the water level sensor 6 detects that the water level has fallen below a first preset height and sends a signal to the main control board 9. The main control board 9 controls the opening and closing mechanism 7 to open, connecting the first through hole 82 and the second through hole 25. This, in turn, opens the pressure relief hole 31. The water pressure pushes the water control element 4 open, connecting the water pipe 21 and the water outlet chamber 22. Water flows into the water outlet hole 23, thereby replenishing the water tank. Water is continuously flowing into the water tank. When the water level sensing mechanism 6 detects that the water level in the water tank is higher than a second preset height, the water level sensing mechanism 6 sends a signal to the main control board 9, which controls the opening and closing hole mechanism 7 to close, thereby interrupting the first through hole 82 and the second through hole 25, that is, closing the pressure relief hole 31, thereby increasing the pressure in the back pressure chamber 32 and pushing the water control member 4 toward the water pipe 21 to close the water pipe 21, so that the water pipe 21 and the water outlet chamber 22 are not connected, thereby stopping water from flowing into the water tank.

[0047] Correspondingly, the present invention also discloses a toilet, comprising a water tank (not shown) and the water inlet valve installed in the water tank. The specific structure of the water inlet valve is as described above and will not be repeated here.

[0048] In summary, the utility model provides a water inlet valve and a toilet, which effectively close the pressure relief hole and improve the accuracy of water inlet control.

[0049] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
