Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom water inlet valves, specifically relating to a quick-release mechanism and a water inlet valve. Background Technology

[0002] The toilet tank inlet valve inevitably needs cleaning or maintenance during use, making its ease of installation and removal crucial. Traditionally, a nut and screw connection is used for installation and removal. This method is cumbersome; due to the size and internal layout of the tank, it's difficult to reach in with hands or tools, making installation and removal very challenging and requiring further improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a quick-release mechanism and a water inlet valve.

[0004] The present invention adopts the following technical solution:

[0005] A quick-release mechanism for an inlet valve is provided between the inlet valve body and the inlet pipe, and includes a quick-release connector, a limiting component, and a reset component.

[0006] A quick-release connector is connected to the lower end of the inlet valve body, and a water flow channel is provided inside for water supply. The lower end of the inlet valve body is embedded in the upper end of the water flow channel.

[0007] A limiting component is movably disposed in a quick-release connector to fix the inlet valve body embedded in the water flow channel. It includes a limiting seat that can move back and forth relative to the water flow channel and a clearance hole disposed in the limiting seat for the lower end of the inlet valve body to pass through. The quick-release connector is provided with a moving cavity that extends inward from its side to communicate with the water flow channel for the limiting seat to move.

[0008] The reset component is located between the outside of the quick-release connector and the limit seat. It moves the limit seat outward away from the water flow channel until its inner wall abuts against the outer wall of the inlet valve body, thus fixing the inlet valve body.

[0009] Furthermore, the limiting seat includes a main body segment movably disposed in the moving cavity and two limiting push rods disposed opposite to each other on both sides of the main body segment on the outside of the quick-release connector, and the reset assembly is disposed between the two limiting push rods and the outside of the quick-release connector.

[0010] Furthermore, the reset assembly includes two spring seats that are respectively disposed on the outside of the quick-release connector and opposite to the two limiting push rods, and two reset springs that are respectively disposed in the two spring seats and connected to the opposite limiting push rods. The spring seats are provided with mounting grooves for installing the reset springs.

[0011] Furthermore, the inner wall of the movable cavity is provided with two inwardly protruding limiting bosses, and the two sides of the main body section are respectively provided with two limiting parts that can abut against the relative limiting bosses, and the limiting parts are located inside the relative limiting bosses.

[0012] Furthermore, the limiting assembly also includes a limiting piece that can be moved up and down in the limiting seat. The limiting seat is provided with a sliding groove extending upward from its bottom surface for the limiting piece to move. The inner wall of the sliding groove is provided with two inwardly protruding positioning parts. The outer side of the limiting piece is provided with two outwardly protruding anti-detachment parts that respectively cooperate with the two positioning parts. When the limiting piece moves upward until the lower end of the anti-detachment part abuts against the upper end of the relative positioning part, the limiting piece is housed in the sliding groove, and the limiting seat can move in the moving cavity. When the limiting piece moves downward until the anti-detachment part is below the positioning part, the limiting piece abuts against the outer side of the quick-release connector to prevent the limiting seat from moving inward.

[0013] Furthermore, the chute includes a guide section, a transition section, and a constraint section arranged sequentially from bottom to top. The diameter of the guide section gradually decreases from bottom to top, the diameter of the constraint section is larger than the diameter of the transition section, and the positioning part is disposed on the inner wall of the constraint section.

[0014] Furthermore, the limiting piece includes a limiting piece body and two limiting segments that are disposed opposite to each other and extend upward from the upper end of the limiting piece body, and the two anti-detachment parts are respectively disposed on the outer side of the two limiting segments.

[0015] A water inlet valve is disposed in a toilet tank, including a water inlet valve body and a quick-release mechanism as described above connected to the lower end of the water inlet valve body.

[0016] Furthermore, the lower end of the water inlet valve body includes a positioning section, a fixing section, and a sealing section arranged sequentially from top to bottom. The inner wall of the clearance hole abuts against the outer wall of the fixing section to fix the water inlet valve body. A sealing ring is fitted around the outer periphery of the sealing section to seal and connect with the water flow channel.

[0017] Furthermore, the outer circumference of the positioning section is provided with multiple positioning ribs, and the inner wall of the upper end of the water flow channel is provided with multiple positioning grooves that can cooperate with the positioning ribs.

[0018] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: This application, by defining the structure of the quick-release mechanism, sets a limiting seat in the quick-release connector to fix the inlet valve body, and the limiting seat, under the action of the reset component, always has a tendency to move outward, so that the inner wall of the relief hole abuts against the lower end of the inlet valve body, thereby fixing the inlet valve body. When it is necessary to remove the limiting valve body, it is only necessary to move the limiting seat inward, so that the inner wall of the relief hole disengages from the outer side of the inlet valve body, and the valve body is then removed. The inlet valve body can be disassembled from the quick-release connector simply by moving it upwards. The overall operation is simple, and the upper end of the limit seat is inclined with a guide surface to guide the inlet valve body smoothly into the clearance hole. In addition, the limit seat is also equipped with a limit plate that moves up and down. After the inlet valve body and the quick-release connector are installed in place, pull down the limit plate so that the limit plate abuts against the outside of the quick-release connector, preventing the limit seat from moving further inwards. This prevents the limit seat from being accidentally moved inwards by external force, causing the inlet valve body to detach from the quick-release connector and affecting the normal use of the inlet valve.

Detailed Implementation

[0033] The present invention will be further described below through specific embodiments.

[0034] Reference Figure 1 As shown, a water inlet valve is installed in a toilet tank and connected to a water inlet pipe in the toilet tank. It includes a water inlet valve body 1 and a quick-release mechanism 2 connected between the water inlet valve body 1 and the water inlet pipe. The quick-release mechanism 2 includes a quick-release connector 3, a limiting component 4, and a reset component 5.

[0035] Reference Figures 2 to 3 As shown, the quick-release connector 3 is connected to the lower end of the inlet valve body 1, and its interior is provided with a water flow channel 31 through which water flows. The lower end of the inlet valve body 1 is embedded in the upper end of the water flow channel 31, which includes a positioning section 11, a fixing section 12, and a sealing section 13 arranged sequentially from top to bottom. A sealing ring is fitted around the outer periphery of the sealing section 13 to form a sealing connection with the quick-release connector 3. Specifically, refer to... Figure 4As shown, multiple positioning ribs 14 are distributed around the outer periphery of the positioning section 11, and multiple positioning grooves 32 that can cooperate with the positioning ribs 14 are distributed around the inner circumference of the upper end of the water flow channel 31. When the water inlet valve body 1 is connected to the quick-release connector 3, the multiple positioning ribs 14 are first embedded into the corresponding positioning grooves 32 to achieve the positioning of the water inlet valve body 1 and the quick-release connector 3. Furthermore, a limiting step 33 is provided at the upper end of the water flow channel 31 to restrict the further embedding of the water inlet valve body 1.

[0036] The limiting component 4 is laterally movable in the quick-release connector 3 to fix the inlet valve body 1 embedded in the water flow channel 31. It includes a limiting seat 41 that can move back and forth relative to the water flow channel 31, a clearance hole 42 in the limiting seat 41 for the lower end of the inlet valve body 1 to pass through, a guide surface 43 inclined at the upper end of the clearance hole 42 to guide the lower end of the inlet valve body 1 to enter, and a limiting piece 44 that can move up and down in the limiting seat 41. The quick-release connector 3 is provided with a moving cavity 34 that extends inward from its side to communicate with the water flow channel 31 for the limiting seat 41 to move. The moving cavity 34 extends inward from one side of the quick-release connector 3 to pass through the other side of the quick-release connector 3. When the inlet valve body 1 is fixed, the inner wall of the clearance hole 42 abuts against the outer wall of the fixing section 12 so that the inlet valve body 1 is fixed in the quick-release connector 3 in conjunction with the limiting step 33. Specifically, the limiting seat 41 is provided with a sliding groove 413 extending upward from its bottom surface for the limiting piece 44 to move. The inner wall of the sliding groove 413 is provided with two inwardly protruding positioning parts 414, and the outer side of the limiting piece 44 is provided with two outwardly protruding anti-detachment parts 443 that respectively cooperate with the two positioning parts 414. When the limiting piece 44 moves upward until the lower end of the anti-detachment part 443 abuts against the upper end of the relative positioning part 414, the limiting piece 44 is housed in the sliding groove 413, and the limiting seat 41 can move in the moving cavity 34. When the limiting piece 44 moves downward until the anti-detachment part 443 is below the relative positioning part 414, the limiting piece 44 abuts against the outer side of the quick-release connector 3, preventing the limiting seat 41 from moving inward, so that the water inlet valve body 1 cannot be disengaged from the quick-release connector 3. The limiting piece 44 is used to limit the movement of the limiting seat 41, preventing accidental contact with the limiting seat 41 that would cause the inlet valve body 1 to disengage from the quick-release connector 3, thus ensuring the normal use of the inlet valve.

[0037] The limiting seat 41 includes a main body section 411 movably disposed in the moving cavity 34 and two limiting push rods 412 oppositely disposed on both sides of the main body section 411 outside the quick-release connector 3. A clearance hole 42 is disposed in the main body section 411. Specifically, two inwardly protruding limiting bosses 35 are disposed opposite each other on the inner wall of the moving cavity 34. Two limiting portions 415 are respectively disposed on both sides of the main body section 411, which can abut against the opposite limiting bosses 35. The limiting portions 415 are located inside the opposite limiting bosses 35. The cooperation between the limiting portions 415 and the opposite limiting bosses 35 prevents the limiting seat 41 from detaching from the moving cavity 34 during outward movement.

[0038] The limiting piece 44 includes a limiting piece body 441 and two limiting segments 442 that are oppositely disposed on the upper end of the limiting piece body 441 and extend upward. Two anti-detachment parts 443 are respectively disposed on the outer side of the two limiting segments 442. Correspondingly, the slide groove 413 includes a guide section 4131, a transition section 4132 and a constraint section 4133 arranged sequentially from bottom to top. The diameter of the guide section 4131 gradually decreases from bottom to top, the transition section 4132 is set with a constant diameter, the diameter of the constraint section 4133 is larger than the diameter of the transition section 4132, and the positioning part 414 is disposed on the inner wall of the constraint section 4133.

[0039] Reference Figure 6 and Figure 9 As shown, the reset assembly 5 is located between the quick-release connector 3 and the two limiting push rods 412 on the outside, causing the limiting seat 41 to move outward away from the water flow channel 31 and return to its original position. It includes two spring seats 51 respectively located on the outside of the quick-release connector 3 and opposite to the two limiting push rods 412, and two reset springs 52 respectively located in the two spring seats 51 and connected to the opposite limiting push rods 412. When the inlet valve body 1 is fixed, during the outward movement of the limiting seat 41, the inner wall of the clearance hole 42 will abut against the outer wall of the fixed section 12, preventing the limiting seat 41 from continuing to move outward. However, under the action of the reset springs 52 on both sides, the limiting seat 41 will always have a tendency to move outward, so that the inlet valve body 1 is stably fixed in the quick-release connector 3, ensuring the normal use of the inlet valve. Specifically, the spring seat 51 is provided with a mounting groove 53 for installing the reset springs 52.

[0040] Reference Figures 11 to 12 As shown, when the inlet valve body 1 is connected to the quick-release connector 3, the limiting plate 44 is completely housed in the slide groove 413, and the lower end of the inlet valve body 1 is embedded in the water flow channel 31, so that the multiple positioning ribs 14 at the lower end of the inlet valve body 1 are aligned with the relative positioning grooves 32. Continuing to move downwards, the positioning ribs 14 of the inlet valve body 1 are embedded in the relative positioning grooves 32, and the movement continues downwards. When the lower end of the inlet valve body 1 abuts against the upper end of the limiting seat 41, the inlet valve body 1 continues to move downwards, and the inlet valve body 1 is on the guide surface. Under the guidance of 43, the spring force on the limiting seat 41 is overcome, causing the limiting seat 41 to move inward. The lower end of the water inlet valve body 1 enters the relief hole 42 and continues to move downward. When the lower end of the water inlet valve body 1 is installed in place against the limiting step 33, it will move outward and reset under the action of the reset spring 52, so that the inner wall of the relief hole 42 abuts against the outer side of the fixed section 12. At the same time, the limiting piece 44 is pulled down, so that the limiting piece 44 abuts against the outer side of the quick-release connector 3, thus completing the connection between the water inlet valve body 1 and the quick-release connector 3.

[0041] Reference Figures 7 to 10As shown, when the inlet valve body 1 is disconnected from the quick-release connector 3, the limiting plate 44 moves upward, so that the anti-detachment part 443 moves upward to the upper end of the relative positioning part 414, and then the limiting seat 41 moves inward, so that the inner wall of the relief hole 42 is released from abutment with the lower end of the inlet valve body 1. At this time, moving the inlet valve body 1 upward can separate the inlet valve body 1 from the quick-release connector 3.

[0042] This application employs a quick-release mechanism 2 structure, in which a limiting seat 41 is provided in the quick-release connector 3 to fix the inlet valve body 1. Under the action of the reset component 5, the limiting seat 41 has a constant outward tendency, causing the inner wall of the clearance hole 42 to abut against the lower end of the inlet valve body 1, thus fixing the inlet valve body 1. When it is necessary to remove the inlet valve body 1, simply move the limiting seat 41 inward, causing the inner wall of the clearance hole 42 to disengage from the outer side of the inlet valve body 1, and then move the inlet valve body 1 upward to reconnect the inlet valve body 1 with the quick-release connector. The disassembly of 3 is simple in operation. The upper end of the limiting seat 41 is inclined with a guide surface 43 to guide the water inlet valve body 1 smoothly into the clearance hole 42. In addition, the limiting seat 41 is also provided with a limiting piece 44 that moves up and down. When the water inlet valve body 1 and the quick-release connector 3 are installed in place, the limiting piece 44 is pulled down so that the limiting piece 44 abuts against the outer side of the quick-release connector 3, so that the limiting seat 41 cannot continue to move inward. This prevents the limiting seat 41 from being accidentally moved inward by external force, causing the water inlet valve body 1 to disengage from the quick-release connector 3 and affecting the normal use of the water inlet valve.

[0043] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
