[0029] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0030] The movable sealing assembly within the drain valve body of the present utility model can open and close the water outlet of the base. By changing the adjusting ring on the sealing assembly, the drainage rate of the water outlet can be changed.

[0031] In order to better understand the above technical solution, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the accompanying drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be fully conveyed to those skilled in the art.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0033] Figures 1 to 7 A drain valve with adjustable drainage rate according to an embodiment of the present utility model includes:

[0034] Drain valve body 1: In one solution, a conduit group 2 is movably provided inside. A base 3 is provided at the lower end of the drain valve body 1. In application, the drain valve body 1 is arranged in the toilet water tank. The toilet water tank has a drainage outlet. The water outlet 31 of the base 3 and the drainage outlet form a drainage channel. The top of the conduit group 2 is provided with an overflow port. When the water level in the water tank is higher than the set value, it is discharged into the toilet through the overflow port to avoid overflow.

[0035] Conduit group 2: It can move up and down. In one solution, a sealing assembly 4 is provided at the bottom end of the conduit group 2. An adjusting ring 43 with a variable size is provided on the sealing assembly 4 and extends into the water outlet 31. The other end of the conduit group 2 is connected to an operating element such as a water tank button or a lever. When the button is pressed, the conduit group 2 is driven to move through the movement of the support rod to change the state. When the conduit group moves upward, the sealing assembly 4 is driven to lift a certain distance, and water flows out from the water outlet 31.

[0036] Base 3; it is provided with a water outlet 31 connected to the toilet, and water flows through the water outlet 31 to achieve the purpose of discharging the toilet water tank; the adjusting ring 43 has different external dimensions and is detachably arranged at the end of the conduit group 2. As described above, the conduit group 2 moves to drive the sealing assembly 4 to open or close the water outlet 31. During this process, by changing the adjusting ring 43 with different dimensions, the drainage speed of the entire water tank is changed.

[0037] In the present utility model, the drainage valve body 1 is fixed and the conduit group 2 moves. The moving stroke of the conduit group 2 is relatively fixed. Therefore, the cycle of the state change of the sealing assembly 4 is also relatively fixed. By changing the external dimensions of the adjusting ring 43, the existence time of the gap between the adjusting ring 43 and the water outlet 31 and the gap size can be changed, so as to realize the control of the total amount of water flowing through the water outlet 31, as shown in the attached Figure 8 and attached Figure 9 As shown, when using adjusting rings 43 with different dimensions, the stroke h is fixed, but the water passing gaps t and t’ are different. It can be foreseen that when a longer stroke h is adopted, the dimensions of the adjusting ring 43 can be selected within a larger range. Therefore, a more gear-based discharge adjustment function can be realized.

[0038] The adjusting ring 43 controls the size of the gap formed by the water outlet 31. This gap is the drainage channel of the device, and the drainage channel determines the drainage flow rate. Therefore, by changing the external dimensions of the detachable adjusting ring 43, the drainage flow rate of the drainage channel can be changed. Combining the attached Figure 8 and the attached Figure 9 schematic diagram, it can be understood that h, t, t’ and the water inlet in the figure together form the entire drainage channel. When different adjusting rings 43 are used, the drainage channel changes. The higher the height of the adjusting ring 43, the smaller the drainage channel, and vice versa.

[0039] Furthermore, the sealing assembly 4 seals the water outlet 31 where water flows out. Due to the pressure difference, the sealing assembly 4 has a tendency to seal the water outlet 31. In this way, when the sealing assembly 4 is sealed, the water stop rubber pad 41 will also be pressed tightly by the water pressure to achieve the effect of active sealing.

[0040] Optionally, the sealing assembly 4 includes a water-stop rubber pad 41, a lower snap ring 42, and an adjusting ring 43 arranged in sequence. The conduit group 2 is provided with a limiting member to limit the up-and-down movement position of the entire seal. The size of the water-stop rubber pad 41 is larger than the size of the water outlet 31 to completely cover the water outlet 31. When the entire structure is sealed, the lower snap ring 42 extends into the water outlet 31. Specifically, the water-stop rubber pad 41 can be made of an elastic material to completely fit the water outlet 31, improving the sealing performance. The lower snap ring 42 and the adjusting ring 44 can extend into the water outlet 31. When the conduit group 2 moves, the water-stop rubber pad 41 moves, and water flows out through the gap between the water-stop rubber pad 41 and the water outlet 31. The presence of the lower snap ring 42 and the adjusting ring 43 makes the aforementioned gap smaller. By adjusting the outer dimension of the lower snap ring 42, the flow rate per unit time of water can be controlled.

[0041] The lower snap ring 42 and the adjusting ring 43 are detachably matched. Through the combination of the two, the size change of the entire sealing assembly 4 is further realized. Specifically, by changing the outer dimension of the adjusting ring 43, the lower snap ring 42 can remain unchanged.

[0042] Furthermore, the lower snap ring 42 forms a convex column 421 in the radial direction, and the adjusting ring 43 is correspondingly provided with a groove 431 for the convex column 421 to be clamped. Through the cooperation of the convex column 421 and the groove 431, the adjusting ring 43 is fixed to the lower snap ring 42. In this solution, a quick-disassembly and assembly cooperation structure is designed. The groove 431 is a structure close to an L shape. The convex column 421 enters from the vertical direction of the L shape, rotates after reaching the bottom, and a bayonet can be provided at the horizontal end of the L shape. After the convex column 421 is clamped, it will not easily come out.

[0043] In the above solution, when the outer diameter, height, and even shape of the adjusting ring 43 change, different displacement change effects can be brought.

[0044] Another solution is that the adjusting ring 43 is composed of multiple monomers 432. These monomers 432 can be exactly the same or have different outer dimensions. By stacking and combining adjusting rings 43 with different dimensions but capable of forming a mating relationship in the axial direction, the effect of changing the size of the sealing assembly 4 is achieved.

[0045] In the above solution, specifically, the end face of the lower snap ring 42 is recessed inward, and a sliding installation groove 4321 is formed on the inner side wall of the recess. The sliding installation groove 4321 has a notch. One end face of the monomer 432 forms a sliding installation block 4322 that can pass through the notch. Through the cooperation of the sliding installation block 4322 and the sliding installation groove 4321, the fixation between the lower snap ring 42 and the monomer 432 is completed. In this solution, the sliding installation groove 4321 can also be L-shaped, enabling the sliding installation block 4322 to slide in and be fixed. In this solution, the monomer 432 has a structure with a reduced diameter inward along the axial direction. This reduced-diameter structure facilitates its insertion into the lower snap ring 42 or the previous monomer 432. The sliding installation groove 4321 is not planar but formed by a dislocation structure. By adopting this solution, when several monomers 432 are combined, a flat outer surface can be achieved.
