[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] like Figure 1 As shown, the structure of the drain valve 9 is shown. A fixing part 91 is provided at the upper end of the housing of the drain valve 9. The fixing part 91 is L-shaped.

[0027] A drain valve fixing assembly, such as Figures 1-8 As shown, the device includes a fixed base 1 and a locking element 2. The locking element 2 is obliquely slidably mounted on the fixed base 1, and a locking groove 21 is provided at the lower end of the locking element 2. During assembly, the fixing part 91 of the drain valve is placed in the locking groove 21. By setting the locking element 2 to slide obliquely, the movement trajectory of the locking groove 21 is downward and horizontal. After locking is completed, the locking groove 21 locks the fixing part 91 to restrict vertical movement and horizontal shaking. In addition, the side wall of the locking groove 21 presses the fixing part 91 against the inner wall of the water tank, further securing the drain valve.

[0028] In one embodiment, such as Figures 1-8 As shown, chamfers 211 are provided on both sides of the locking groove 21. By providing chamfers 211, the opening size of the locking groove 21 is increased, and by providing chamfers 211, the fixing part 91 is guided into the locking groove 21 when the locking member 2 moves diagonally downward.

[0029] In one embodiment, such as Figures 1-8 As shown, guide grooves 22 extend from both sides of the locking member 2, and guide edges 11 that cooperate with the guide grooves 22 are provided on the fixing base 1. The guide edges 11 are placed in the guide grooves 22 to guide the locking member 2 to move obliquely along the guiding direction of the guide edges 11. In a specific embodiment, the openings of the guide grooves 22 on both sides are arranged opposite each other, and the two ends of the guide grooves 22 are open structures; when assembling the locking member 2 and the fixing base 1, the guide edges 11 are aligned with the guide grooves 22 and then inserted to complete the assembly.

[0030] In one embodiment, such as Figures 1-8 As shown, at least one hook 23 is provided on the locking component 2, and a slot 12 that cooperates with the hook 23 is provided on the fixing base 1. When locked, the hook 23 is engaged in the slot 12.

[0031] In one specific embodiment, such as Figures 1-8 As shown, the slot 12 is provided on the guide edge 11, and the hook 23 is provided at the extension position of the guide groove 22. The hook 23 is inserted into the slot 12 to lock the locking element 2.

[0032] In one embodiment, such as Figures 1-8 As shown, two hooks 23 are provided, and they are located on both sides of the locking member 2.

[0033] In one embodiment, such as Figures 1-8 As shown, a grip portion 24 is provided on the locking member 2. The grip portion 24 facilitates the control of the movement of the locking member 2. Specifically, the grip portion 24 is triangular, and the two side walls of the triangle are arc surfaces. Several raised strips are provided at intervals on the surface of the arc surfaces to increase the friction between the fingers and the grip portion 24.

[0034] In one embodiment, such as Figures 1-8 As shown, the fixing base 1 has a recessed positioning groove 13, and the lower end of the locking member 2 protrudes to one side of the fixing base as a positioning part 25. When the locking position is reached, the positioning part 25 is placed in the positioning groove 13 to increase the connection strength between the locking member 2 and the fixing base 1 when locked.

[0035] In the above embodiments, such as Figures 1-8 As shown, the positioning part 25 is a vertically oriented elongated structure. The fixing part 91 of the drain valve 9 is provided with a positioning groove that cooperates with the positioning part 25. The fixing part 25 connects the fixing seat 1 and the positioning groove on the drain valve 9, further locking the drain valve 9.

[0036] In one embodiment, such as Figures 1-8 As shown, a clamping plane 14 is provided at the lower end of the fixing base 1, and a downward pressure is applied to the drain valve 9 by the clamping plane 14. The clamping plane 14 acts on the upper surface of the fixing part 91, thereby restricting the vertical movement of the drain valve 9.

[0037] In one embodiment, such as Figures 1-8 As shown, a reinforcing rib 15 is provided between the pressing plane 14 and the fixed base 1. The reinforcing rib 15 improves the strength of the pressing plane 14.

[0038] When using this utility model, such as Figures 1-8 As shown, the locking steps are as follows: insert the drain valve into the valve seat and rotate the drain valve so that the fixing part 91 is pressed against the inner wall of the water tank. The fixing seat 1 is installed on the upper cover of the water tank. After the drain valve is installed, close the upper cover. At this time, the pressing plane 14 of the fixing seat 1 acts on the fixing part 91 of the drain valve 9. Slide the locking member 2 so that the locking member 2 moves diagonally downward. The fixing part 91 is located in the locking groove 21. After reaching the locking position, the hook 23 is placed in the slot 12, completing the fixing of the locking member 2 in the locking position. At this time, the positioning part 25 on the locking member 2 is inserted into the positioning groove 13, and the fixing part 91 is pressed against the inner wall of the water tank by the locking member 2. Through the above multiple fixings, the drain valve 9 is quickly locked.

[0039] The unlocking process involves pushing the locking member 2 upwards by the grip 24, causing the positioning groove 21 to move away from the fixing part 91, so that the hook 23 can be engaged in another slot 12, thereby fixing the locking member 2 in the unlocked position.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
