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 movement or displacement, making it difficult to accurately transmit the water level sensed by the buoyancy mechanism to the valve assembly, thereby affecting the stability of the valve assembly. Specifically, due to the 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

[0032] 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.

[0033] See also Figure 1-5 The utility model discloses a water inlet valve, comprising a valve group mechanism, a connecting rod assembly and a buoyancy mechanism.

[0034] The valve group mechanism includes a valve control assembly, which includes a valve cover 7, and a pressure relief hole 72 is provided on the top of the valve cover 7; the connecting rod assembly includes a water inlet valve stem 1 and a water inlet connector 2, and the water inlet connector 2 includes a positioning seat 21 and a joint seat 22 provided on the positioning seat 21; the buoyancy mechanism includes a floating assembly, and the floating assembly includes a floating tube 3;

[0035] The water inlet valve stem is provided with a first connecting position 11, a second connecting position 12 and a closing seat 13. The second connecting position 12 and the closing seat 13 are respectively arranged at both ends of the water inlet valve stem 1, and the first connecting position 11 is placed between the second connecting position 12 and the closing seat 13; the water inlet valve stem 1 is movably connected to the valve cover 7 through the first connecting position 11, and the closing seat 13 and the pressure relief hole 72 are arranged correspondingly; the water inlet valve stem 1 is connected to the movable seat 22 through the second connecting position 12, and the positioning seat 21 and the floating tube 3 are fixedly connected.

[0036] The water inlet valve stem of the present invention is connected to the floating tube using a water inlet connector. The flexible joint and positioning seat of the water inlet connector are respectively connected to the water inlet valve stem and the floating tube. The positioning seat and the floating tube are fixedly connected, preventing the water inlet valve stem from being directly connected to the floating tube, which could easily cause the water inlet valve stem to wobble or shift. This ensures that the water level position sensed by the buoyancy mechanism is accurately transmitted to the valve assembly mechanism, thereby ensuring the stability of the valve assembly mechanism. Therefore, the present invention utilizes the coordination of the water inlet valve stem, the water inlet connector, and the floating tube to ensure the stability of the water inlet valve stem, improve the accuracy of water inlet control, and thus prevent water tank overflow.

[0037] Specifically, the distance between the closing seat 13 and the first connection position 11 is smaller than the distance between the first connection position 11 and the second connection position 12. Preferably, the distance between the first connection position 11 and the second connection position 12 is 3-10 times the distance between the closing seat 13 and the first connection position 11. The utility model adopts the principle of leverage and uses the connection between the first connection position and the valve cover as a fulcrum. When the second connection position moves upward, the closing seat moves downward and covers the pressure relief hole to close the pressure relief hole. The distance between the first connection position, the second connection position and the closing seat is set to ensure that the closing seat can tightly cover the pressure relief hole to avoid air leakage.

[0038] The water inlet valve stem 1 is hinged to the valve cover 7 via a first connection position 11 , and the water inlet valve stem 1 is hinged to the articulated seat 22 via a second connection position 12 .

[0039] Preferably, if Figure 3 、 5 As shown, the second connection position 12 is a connection hole; a joint block 221 is provided on the joint seat 22, and the water inlet valve stem 1 is sleeved on the outside of the joint block 221 through the connection hole, so that the water inlet valve stem 1 can rotate around the joint block 221, thereby realizing the hinged connection between the water inlet valve stem 1 and the joint seat 22.

[0040] Preferably, if Figure 3 、 5 As shown, the positioning seat 21 is provided with a positioning groove 211, and a positioning block 31 is provided on the top of the floating tube 3. The positioning block 31 is embedded in the positioning groove 211 to achieve a fixed connection between the positioning seat 21 and the floating tube 3. More preferably, the positioning groove 211 is an annular groove, and the positioning block 31 is provided along the circumference of the floating tube 3.

[0041] Preferably, if Figure 1-2 As shown, the first connection position 11 is a connection block, and a support plate 73 is provided on the top of the valve cover 7. The support plate 73 is sleeved outside the connection block so that the support plate 73 can rotate around the connection block to realize the hinge connection between the water inlet valve stem 1 and the valve cover 7.

[0042] Further, if Figure 1 、 3 As shown, the buoyancy mechanism also includes a buoyancy assembly, comprising a buoy 5 and a floating head 6 disposed within the buoy 5. The floating head 6 is fixedly connected to the floating tube 3. A water inlet hole (not shown) is provided at the bottom of the buoy 5. Water from the water tank enters the buoy 5 through the water inlet hole. The water level within the buoy 5 is the same as that within the water tank. The floating head rises due to the rising water level within the buoy, driving the floating tube upward, which in turn pushes the second connection point of the water inlet valve stem upward via the water inlet connector. Due to the principle of leverage, the closing seat descends and covers the pressure relief hole below it, ultimately completely sealing the pressure relief hole.

[0043] In order to ensure that the floating head and the floating tube rise or fall in the predetermined direction, ensure the stability of the water inlet valve stem, and improve the accuracy of water inlet control. Figure 3 As shown, the buoy 5 is provided with a floating casing 51. The float transfer assembly also includes a floating guide rod 4, which is fixedly connected to the floating casing 51. The floating tube 3 is sleeved outside the floating guide rod 4 and can move back and forth along the floating guide rod 4. The floating casing serves to position the float transfer assembly, using the floating guide rod to guide the floating tube, allowing it to rise or fall in a predetermined direction. Specifically, the floating guide rod 4 is inserted into the floating casing 51 and fixedly connected to it.

[0044] Preferably, if Figure 2 As shown, a pressure relief head 71 is provided on the top of the valve cover 7, and the pressure relief hole 72 is provided on the pressure relief head 71; a closing member 14 is provided on the closing seat 13, and the closing member 14 is made of elastic material; the closing member 14 can cover the pressure relief head 71 through the closing seat 13 to close the pressure relief hole 72.

[0045] The pressure relief head 71 extends upward from the top of the valve cover 7. When the closing seat moves downward, the sealing member can cover and wrap around the pressure relief head, thereby tightly sealing the pressure relief hole, preventing air leakage and ensuring accurate water inlet control. The elastic material is preferably rubber.

[0046] Going further, Figure 2 As shown, the valve assembly mechanism further includes a valve seat 9 and a water pipe 93; the valve control assembly further includes a water control member 8, which is made of an elastic material, preferably rubber.

[0047] The valve seat 9 is provided with a valve cover groove 91, a water flow cavity 92 and a water outlet hole 94 which are connected in sequence. The water control member 8 is fixedly installed in the valve cover groove 91 through the valve cover 7. A back pressure cavity 81 is formed between the valve cover 7 and the water control member 8. The back pressure cavity 81 is connected to the pressure relief hole 72. The water flow pipe 93 is provided in the water flow cavity 92. The water flow pipe 92 is connected or disconnected with the water flow cavity 92 through the water control member 8. The valve group mechanism also includes a valve housing 10 and a water inlet pipe 101 provided in the valve housing 10. The valve housing 10 is installed at the bottom of the valve seat 9. The water inlet pipe 101 is connected to the water flow pipe 93. The water control member 8 is separated from the top of the water flow pipe 93 so that the water flow pipe 93 is connected to the water flow cavity 92. Alternatively, the water control member 8 covers the top of the water flow pipe 93 so that the water flow pipe 93 is disconnected from the water flow cavity 92. The buoy 5 is fixedly installed outside the valve housing 10 through a water inlet sleeve.

[0048] The water from the water inlet pipe 101 enters the water pipe 93 through the bottom end of the water pipe 93, flows into the water cavity 92 through the top end of the water pipe 93, then flows from the water cavity 92 into the water outlet 94, and finally flows into the water tank through the water outlet 94, thereby replenishing the water tank.

[0049] During water inflow, water flows from the inlet pipe to the water passage. Since the tank is drained and the float head is not raised, the height of the second connection point is lower than that of the closure seat. The closure member of the closure seat separates from the pressure relief head, opening the pressure relief hole. The pressure in the backpressure chamber is lower than the pressure in the water passage. As a result, the water pressure on the water control member pushes it upward, separating it from the top of the water passage, thus connecting the water passage and the water chamber. Water in the water passage flows into the water passage and, through the outlet, into the tank for replenishment. During water shut-off, when the water in the tank reaches the operating level, the float head rises, driving the floating tube upward. This, in turn, pushes the second connection point upward via the inlet connection. This leverage mechanism causes the closure seat to move downward, and the closure member presses against the pressure relief head, sealing the pressure relief hole. When the pressure relief hole is fully sealed, the pressure in the backpressure chamber increases, causing the water control member to return to its original position and cover the top of the water passage, effectively shutting off the connection between the water passage and the water chamber, thus shutting off the water inlet valve.

[0050] In addition, if Figure 1-2As shown, the valve assembly mechanism also includes a self-generating mechanism; the self-generating mechanism includes a battery 15 and a hydroelectric generator 16, and the battery 15 and the hydroelectric generator 16 are electrically connected; the hydroelectric generator 16 is installed on the valve seat 9 and extends into the water outlet 94. The battery 15 is preferably a lithium battery.

[0051] 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 main control board and solenoid valve, etc. It is efficient and energy-saving, environmentally friendly and low-cost.

[0052] 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.

[0053] In summary, the utility model provides a water inlet valve and a toilet, which ensure the stability of the water inlet valve stem and improve the accuracy of water inlet control.

[0054] 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.
