[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0021] Now combined Figure 1-8 An automatic opening and closing water tank cover is described, which is connected to a water tank 1 via a drive assembly 2. The drive assembly 2 includes a water tank connecting plate 21 for connecting to the water tank 1 and an upper cover connecting plate 22 for connecting to the water tank cover 3. The water tank connecting plate 21 is provided with a servo motor 23 and a gearbox 24. The output shaft of the servo motor 23 is connected to the input shaft of the gearbox 24. A hinge shaft 25 is fixed on the upper cover connecting plate 22, and a driven gear 26 is coaxially fixed on the hinge shaft 25. The output gear of the gearbox 24 meshes with the driven gear 26. The water tank connecting plate 21 is provided with hinge seats 27 at both ends of the hinge shaft 25, which are rotatably engaged with the hinge shaft 25. A water baffle 28 is provided on the water tank connecting plate 21.

[0022] The hinge seat 27 is provided with a radial rib 271; the water tank cover 3 is provided with an arc-shaped lip 31; when the water tank cover 3 is opened, the arc-shaped lip 31 and the radial rib 271 are interference-fitted.

[0023] The hinge seat 27 is equipped with a booster torsion spring 4. One end of the booster torsion spring 4 is fixed to the end edge of the water tank 1, and the other end extends into the water tank cover 3 and is fixed thereto. The booster torsion spring 4 is in a stress-relieving state when the water tank cover 3 is open and in a stress-accumulating state when it is closed, which helps to overcome the weight of the water tank cover 3 when the cover is opened and reduces the energy consumption of the servo motor 23.

[0024] The input shaft of the gearbox 24 is equipped with a drive wheel, and two meshing transmission gears are provided between the drive wheel and the output gear of the gearbox 24. This increases the distance between the hinge shaft 25 and the output shaft of the servo motor 23, making it easier for the servo motor 23 to be installed outside the water tank.

[0025] The end edge of the water tank 1 is fixed between the hinge seat 27 and the water tank connecting plate 21. The water baffle 28 at the upper end of the gearbox 24 passes through the end edge of the water tank 1. The hinge seat 27 is located on both sides of the water baffle 28. The hinge seat 27 is fixed to the end edge of the water tank 1 and the water tank connecting plate 21.

[0026] The opening of the water shield 28 faces away from the opening of the water tank 1.

[0027] The gearbox 24 is a reduction gearbox.

[0028] The upper cover connecting plate 22 is fixedly connected to the water tank cover 3, and the upper surface of the upper cover connecting plate 22 is parallel to the surface of the water tank cover 3. The axis of the hinge shaft 25 is parallel to the edge where the water tank cover 3 and the water tank 1 are hinged.

[0029] like Figure 8As shown, the water baffle 28 and the driven gear 26 are located on the upper part of the end edge of the water tank 1, and the servo motor 23 is located on the lower part of the end edge of the water tank, outside the water tank.

[0030] The gearbox 24 can be driven simply by controlling the servo motor 23. Since the output gear of the gearbox 24 meshes with the driven gear 26, it can drive the hinge shaft 25 fixed to the upper cover connecting plate 22, thereby driving the opening and closing of the water tank cover 3.

[0031] Since the water tank connecting plate 21 is fixed to the water tank 1, the water baffle 28 partially wraps around the driven gear 26 and its opening faces away from the opening of the water tank 1. Therefore, it can minimize the impact of the rinsing water inside the water tank on the drive component. The hinge seat 27 is provided with radial ribs 271; the water tank cover 3 is provided with arc-shaped lip 31. When the water tank cover 3 is opened, the arc-shaped lip 31 and the radial ribs 271 are interference-fitted. The deformation and large friction force generated by the arc-shaped lip 31 can play a role in buffering the opening of the cover. This utility model is suitable for use in the water tank of a teacup washing machine.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0033] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
