Description

Technical Field

[0001] This utility model relates to the structure of a water replenishment device for a toilet tank. Background Technology

[0002] Most existing toilets replenish the water seal after flushing to ensure sufficient water volume and prevent odors from escaping from the drain pipe and polluting indoor air. Current technology typically uses a portion of the water from the inlet valve in the toilet tank for this replenishment. However, different toilet designs require different amounts of replenishment water; therefore, a customized water supply is needed for each toilet model.

[0003] As an example of the current structure of the water replenishment device for toilet tanks, one can refer to the structure disclosed in patent application number CN201610812342.2 entitled "A water replenishment device and water replenishment method suitable for flushing toilets". Its parts are complex and numerous, and are inconvenient to install and maintain.

[0004] Based on the above problems, it is necessary to improve the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a water replenishment device structure for a toilet tank, in order to solve the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water replenishment device structure for a toilet tank, comprising: A base having a cavity with perforations on both sides of the cavity, a flexible tube being inserted into the cavity through the perforation on one side and exiting through the perforation on the other side; A cam extruder is rotatably disposed within the cavity, and the hose is disposed between the cavity wall and the surface of the cam extruder. The cam extruder has a first position and a second position on the base and can rotate between the first position and the second position. In the first position, the cam extruder does not extrude the hose and the hose is fully open. In the second position, the cam extruder extrudes the hose so that the hose is fully closed. As the cam extruder rotates from the first position to the second position, the distance between the surface of the cam extruder and the cavity wall gradually decreases.

[0007] In the above technical solution, a connector for inserting the base onto the pipe is provided below the base.

[0008] In the above technical solution, teeth with the same oblique angle as the insertion direction of the flexible tube are provided inside the cavity.

[0009] In the above technical solution, the end of the cam extruder is formed with an anti-disengagement seat, and a corresponding anti-disengagement hole is provided on the base.

[0010] In the above technical solution, a guide portion is provided outside the perforation.

[0011] In the above technical solution, a gear slot is provided on the end cover of the cam extruder, and a protruding post matching the shape of the gear slot is provided on the base. A gear mark is provided on the end cover corresponding to the position of the gear slot.

[0012] The present invention provides a water replenishment device structure for a toilet tank, the advantages of which are: the water replenishment device structure of the present invention is very simple, with only two parts, both of which are adjusted by the cam on the cam extrusion component squeezing the hose to regulate the water volume.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 The present invention provides a toilet tank refill device structure, characterized in that it includes: The base 1 has a cavity 100, and perforations 11 are provided on both sides of the cavity. A flexible tube 101 is inserted into the cavity through the perforation on one side and exits through the perforation on the other side. The cam extruder 2 is rotatably disposed within the cavity, and the hose 101 is disposed between the cavity wall and the surface of the cam extruder; The cam extruder 2 has a first position and a second position on the base, and can rotate between the first position and the second position. In the first position, the cam extruder does not extrude the hose, and the hose is fully open. In the second position, the cam extruder extrudes the hose so that the hose is fully closed. As the cam extruder 2 rotates from the first position to the second position, the distance between the surface of the cam extruder and the cavity wall gradually decreases.

[0019] In the above structure, the flow rate through the hose is adjusted by controlling the cross-sectional size of the hose by squeezing the hose. In addition, since the cam structure and the hose surface can achieve self-locking through friction, the cam structure will not deflect when it rotates to the preset position without external force. Furthermore, as the cam squeezing member 2 rotates from the first position to the second position, the distance between the surface of the cam squeezing member and the cavity wall of the cavity gradually decreases. Therefore, the flow rate of the hose can be adjusted steplessly by the cam squeezing member 2.

[0020] The base 1 is provided with a connector 12 for inserting the base 1 into the pipe fitting. This facilitates the fixing of the entire water supply device above the pipe fitting.

[0021] The cavity 100 contains teeth with the same bevel angle in the direction of hose insertion. This structure confines the hose between the two perforations, and the teeth apply bias pressure to the closed lower end of the hose, ensuring a more secure confinement and preventing hose displacement.

[0022] The cam extruder 2 has an anti-detachment seat 20 formed at its end, and a corresponding anti-detachment hole 14 is provided on the base 1. With this structure, the cam extruder 2 can be directly installed into the base 1 by press-fitting. A guide portion 13 is provided outside the through hole 11 to guide the insertion of the flexible hose.

[0023] The end cap of the cam extruder 2 is provided with a gear slot 21, and a corresponding protruding post 15 matching the shape of the gear slot 21 is provided on the base 1. A gear position indicator is provided on the end cap corresponding to the gear slot position. This structure allows the user to easily understand the current gear position of the water replenisher. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
