Description

Technical Field

[0001] This utility model belongs to the technical field of toilet accessories, and specifically refers to a water inlet valve adjustment structure. Background Technology

[0002] In existing technology, the inlet valve installed inside a toilet tank mainly includes an inlet valve body, an inner float, an outer float, a control valve, an adjusting screw, and a swing arm. The inlet valve body is connected to the water supply pipe and contains an inlet channel. The control valve is installed on the inlet valve body and controls the opening and closing of the inlet channel. The adjusting screw is generally connected below the inlet valve body. Both the inner and outer floats are fitted onto the adjusting screw, with the inner float inside the outer float. The two ends of the swing arm are pivotally connected to the inner float and the control valve, respectively, to control the opening and closing of the valve by the up-and-down movement of the inner float within the outer float, thus controlling whether water enters the toilet. In this structure, the height of the outer float on the adjusting screw determines the water level in the toilet tank, and the overall installation height needs to be adjusted according to different tank interior heights, making the ease of adjustment of the outer float very important.

[0003] The problem with the above structure is that the outer float and the adjusting screw are assembled by a threaded connection, and adjusting the height of the outer float requires rotating it at a certain angle or even several times, which is cumbersome. Utility Model Content

[0004] The main purpose of this utility model is to provide an inlet valve adjustment structure to solve the problems existing in the prior art, which can quickly adjust the height of the outer float and is easy to operate.

[0005] To achieve the above objectives, the solution of this utility model is: A water inlet valve regulating structure includes an inlet body, a lower sleeve, an outer float, and a locking ring. The lower end of the inlet body is configured as an outlet pipe. The upper end of the lower sleeve is sealed and fitted onto the circumferential surface of the outlet pipe. The circumferential surface of the lower sleeve is provided with a plurality of toothed grooves arranged along its own axial direction. The outer float is fitted onto the circumferential surface of the lower sleeve and is provided with a spring arm. A limit block is provided on the inner side of the movable end of the spring arm, and the limit block is movably fitted into one of its toothed grooves. The locking ring is movably fitted onto the circumferential surface of the outer float and is used to lock or unlock the deformation of the spring arm by rotational movement, and to restrict or allow the limit block to disengage from the corresponding toothed groove by up and down movement.

[0006] The lower sleeve is also provided with a guide groove extending along its own axis on its circumferential surface, and the inner wall of the outer float is provided with a guide block that slides in the guide groove.

[0007] The outer buoy includes a buoy body and a connecting part sleeved on the circumference of the lower sleeve; the spring arm is disposed on the lower end face of the connecting part, and the locking ring is movably sleeved on the connecting part.

[0008] Preferably, a pressure block is provided on the outer side of the spring arm; when the inner wall of the locking ring contacts the pressure block, it presses the spring arm against the lower sleeve so that the limiting block is tightly fitted in the tooth groove; when the inner wall of the locking ring separates from the pressure block, it provides deformation space for the spring arm so that the limiting block disengages from the corresponding tooth groove.

[0009] The locking ring is axially movable and fits onto the circumferential surface of the connecting portion; the circumferential surface of the connecting portion is provided with a laterally arranged limiting boss; the upper end face of the locking ring is provided with a spring buckle, the movable end of the spring buckle being movably fitted above or below the limiting boss; when the movable end of the spring buckle is above the limiting boss, the locking ring does not contact the pressure block; when the movable end of the spring buckle is below the limiting boss, the inner wall of the locking ring is tightly fitted with the pressure block. Preferably, a guide slope is provided above the pressure block.

[0010] Alternatively, the locking ring rotatably engages with the circumferential surface of the connecting portion; the circumferential surface of the connecting portion is provided with a vertically positioned limiting boss; the upper end face of the locking ring is provided with a spring buckle, the movable end of the spring buckle movably engages with the left or right side of the limiting boss, and the inner wall of the locking ring is provided with a clearance groove for the pressure block to be embedded; when the movable end of the spring buckle is on one side of the limiting boss, the pressure block is in the clearance groove, and the locking ring does not contact the pressure block; when the movable end of the spring buckle is on the other side of the limiting boss, the inner wall of the locking ring is tightly engaged with the pressure block. Preferably, a baffle is provided on the side of the limiting boss, and when the spring buckle engages between the baffle and the limiting boss, the locking ring is in a locked position; both sides of the clearance groove are provided with chamfers.

[0011] A water inlet passage is provided at the upper end of the water inlet body, and a control valve is provided between the water inlet passage and the water outlet pipe. An inner float is provided inside the outer float, and the inner float and the control valve are connected by a swing arm. When the inner float descends to its limit position, the control valve is opened, and when the inner float rises to its limit position, the control valve is closed. A float drain outlet is provided at the bottom of the float body, and a one-way float is provided below the float drain outlet.

[0012] After adopting the above technical solution, the present invention has the following technical effects: This invention utilizes the elastic arm of the outer float and the toothed groove of the lower sleeve to limit the height of the outer float. Because the elastic arm itself is elastic, when the locking ring is not in the locked position, the user can directly push and pull the outer float axially in the lower sleeve to quickly adjust the height of the outer float, without having to rotate the outer float a certain angle or several turns as required by the threaded connection method in the prior art, making the operation more convenient. The user only needs to use minimal movements to switch the locking ring between the locked and unlocked positions. The lower sleeve is not only a positioning component during the installation of the outer float, but also a pipe for the water inlet valve, making it multi-functional and simplifying the overall structure.

Cover. Detailed Implementation

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] refer to Figure 1-7 As shown, this utility model discloses an inlet valve adjustment structure, including an inlet body 1, a lower sleeve 2, an outer float 3, and a locking ring 4; The lower end of the water inlet body 1 is configured as the water outlet pipe 11; The upper end of the lower sleeve 2 is sealed and fitted onto the circumferential surface of the outlet pipe 11; the circumferential surface of the lower sleeve 2 is provided with a number of toothed grooves 21 arranged at equal intervals along its own axial direction. The outer float 3 is sleeved on the circumferential surface of the lower sleeve 2 and is provided with a spring arm 31; a limit block 32 is provided on the inner side of the movable end of the spring arm 31, and the limit block 32 is movably fitted in one of its tooth grooves 21 to limit the height of the outer float 3. The locking ring 4 is movably fitted on the circumference of the outer float 3. It is used to lock or unlock the deformation of the spring arm 31 by rotating, and then to restrict or allow the limit block 32 to disengage from the corresponding tooth groove 21 by moving up and down.

[0023] Through the above solution, this utility model utilizes the cooperation between the spring arm 31 of the outer float 3 and the toothed groove 21 of the lower sleeve 2 to limit the height of the outer float 3. Since the spring arm 31 itself is elastic, when the locking ring 4 is not in the locked position, the user can directly push and pull the outer float 3 axially in the lower sleeve 2 to quickly adjust the height of the outer float 3, without having to rotate the outer float 3 at a certain angle or several turns as required by the threaded connection method in the prior art, making the operation more convenient; the user only needs to use very few movements to switch the locking ring 4 between the locked and unlocked positions; the lower sleeve 2 is not only a positioning component when installing the outer float 3, but also a pipeline for water inlet valve, making it multi-functional and the overall structure more concise.

[0024] The following are specific embodiments of the present invention.

[0025] The lower sleeve 2 is also provided with a guide groove 22 extending along its own axial direction on its circumferential surface, and a guide block 33 is provided on the inner wall of the outer float 3, which is slidably fitted in the guide groove 22. Through the cooperation of the guide groove 22 and the guide block 33, the up and down movement of the outer float 3 on the circumferential surface of the lower sleeve 2 during the adjustment process is guided, so as to prevent the outer float 3 from deflecting and affecting the stability of other structures.

[0026] The aforementioned outer buoy 3 includes a buoy body 34 and a connecting part 35 that are sleeved on the periphery of the lower sleeve 2; the aforementioned spring arm 31 is disposed on the lower end face of the connecting part 35, and the locking ring 4 is movably sleeved on the connecting part 35.

[0027] Furthermore, a pressure block 36 is provided on the outer side of the aforementioned spring arm 31; when the inner wall of the locking ring 4 contacts the pressure block 36, it presses the spring arm 31 down into the sleeve 2 so that the limiting block 32 is tightly fitted in the tooth groove 21; when the inner wall of the locking ring 4 separates from the pressure block 36, it provides deformation space for the spring arm 31 so that the limiting block 32 disengages from the corresponding tooth groove 21.

[0028] Regarding the mating structure between the locking ring 4 and the connecting part 35, this utility model provides two methods: (1) The locking ring 4 is axially movable and fits on the circumferential surface of the connecting part 35; the circumferential surface of the connecting part 35 is provided with a transversely arranged limiting boss 37; the upper end surface of the locking ring 4 is provided with a spring buckle 41, and the movable end of the spring buckle 41 is movably fitted above or below the limiting boss 37; when the movable end of the spring buckle 41 is above the limiting boss 37, the locking ring 4 does not contact the pressure block 36; when the movable end of the spring buckle 41 is below the limiting boss 37, the inner wall of the locking ring 4 is tightly fitted with the pressure block 36. Specifically, a guide slope 37 can be provided above the pressure block 36 to make the axial movement of the locking ring 4 smoother and to gradually squeeze the pressure block 36 during the movement.

[0029] (2) The locking ring 4 is rotatably fitted on the circumferential surface of the connecting part 35; the circumferential surface of the connecting part 35 is provided with a vertically arranged limiting boss 37'; the upper end surface of the locking ring 4 is provided with a spring buckle 41, the movable end of the spring buckle 41 is movably fitted on the left or right side of the limiting boss 37', and the inner wall of the locking ring 4 is provided with a relief groove 42 for the pressure block 36 to be embedded; when the movable end of the spring buckle 41 is on one side of the limiting boss 37', the pressure block 36 is in the relief groove 42, and the locking ring 4 does not contact the pressure block 36; when the movable end of the spring buckle 41 is on the other side of the limiting boss 37', the inner wall of the locking ring 4 is tightly fitted with the pressure block 36. Specifically, a baffle 39 can be provided on the side of the limiting boss 37'. When the spring buckle 41 is engaged between the baffle 39 and the limiting boss 37', the locking ring 4 is in the locked position and will not rotate excessively. Both sides of the relief groove 42 are provided with chamfers 43 so that the pressure block 36 can slide out of the relief groove 42 more easily.

[0030] The above illustrations show that the two methods are combined in the same component. In actual production, one method can be selected according to the requirements.

[0031] Meanwhile, an inlet passage 12 is provided at the upper end of the inlet body 1, and a control valve 5 is provided between the inlet passage 12 and the outlet pipe 11. An inner float 6 is provided inside the outer float 3, and the inner float 6 and the control valve 5 are connected by a swing arm 7. When the inner float 6 descends to its limit position, the control valve 5 is opened, and when the inner float 6 rises to its limit position, the control valve 5 is closed. In this embodiment, a float box drain outlet 30 is provided at the bottom of the float box body 34, and a one-way float 8 is provided below the float box drain outlet 30.

[0032] Secondly, this utility model also includes an upper cover 9 sleeved above the outer float 3, used to cover accessories such as the control valve 5 and the inner float 6.

[0033] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
