[0023] To elaborate on the idea and purpose of this application, the following will further illustrate this application in conjunction with the drawings and specific embodiments.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs; the terms used in the description of the present application in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the description and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", "left", "right", etc. in the description and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0025] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0026] The first embodiment is as Figures 1 to 5 shown. An embodiment of this application provides a leak-proof water storage tank, including an upper cover 10 and a water storage tank body 20 for containing liquid. The water storage tank body 20 is provided with a liquid inlet 21. One side of the upper cover 10 is rotatably connected to the liquid inlet 21. The inner edge of the upper cover 10 is provided with a seal 30. After the upper cover 10 is closed with the liquid inlet 21, the seal 30 is in close contact with the outer wall of the liquid inlet 21.

[0027] As Figures 1 to 5As shown in the figure, the liquid inlet 21 is provided at the top of the water storage tank body 20. Liquid can flow into the water storage tank body 20 from the liquid inlet 21. The shape of the liquid inlet 21 can be set as required, and it can be circular, polygonal or irregular. The diameter of the liquid inlet 21 is relatively large. After the upper cover 10 is opened, the seal 30 will not affect the inflow of liquid into the liquid inlet 21. The upper cover 10 is made of a hard material, and a seal 30 is provided at the inner edge of the upper cover 10. The seal 30 is arranged in a ring shape at the inner edge of the upper cover 10 and is located above the rotating connection. When the upper cover 10 is closed with the liquid inlet 21, the seal 30 is in close contact with the outer wall of the liquid inlet 21. Therefore, it can prevent the liquid in the water storage tank body 20 from leaking; the shape of the liquid inlet 21 can be various, and the diameter of the liquid inlet 21 is relatively large, slightly smaller than the upper cover 10, which is convenient for adding water into the water storage tank body 20.

[0028] As Figures 1 to 5 shown, the seal 30 is injection-molded or inlaid with the inner edge of the upper cover 10. The seal 30 has a certain elasticity. When the upper cover 10 is closed with the liquid inlet 21, the seal 30 is in close contact with the outer wall of the liquid inlet 21, which can prevent the liquid in the water storage tank body 20 from flowing out.

[0029] As Figures 1 to 5 shown, a rotating part 11 extends from the inner edge of the upper cover 10 into the water storage tank body 20. The rotating part 11 is provided with a rotating hole 12, a sliding groove 13 and a positioning hole 14. The sliding groove 13 and the positioning hole 14 are located on the same arc. The side wall of the liquid inlet 21 is provided with a rotating shaft 23 and a guiding shaft 24. The rotating shaft 23 is rotatably connected with the rotating hole 12, and the guiding shaft 24 slides along the sliding groove 13 and the positioning block.

[0030] In other embodiments, as Figures 1 to 5 shown, the sliding groove 13 is an arc-shaped structure. When the upper cover 10 is rotated, the rotating shaft 23 rotates along the rotating hole 12, and the guiding shaft 24 slides back and forth along the sliding groove 13. During the process of closing the upper cover 10 with the liquid inlet 21, the guiding shaft 24 slides along the sliding groove 13. After the upper cover 10 is closed with the liquid inlet 21, the guiding shaft 24 slides into the positioning hole 14. At this time, the upper cover 10 and the liquid inlet 21 are in a relatively locked state, and the seal 30 is in close contact with the outer wall of the liquid inlet 21. When the water storage tank body 20 is tilted or inclined, it can prevent the liquid in the water storage tank body 20 from flowing out.

[0031] In other embodiments, as Figures 1 to 5As shown, the bottom of the rotating part 11 is provided with an air-avoiding gap 15, the sliding groove 13 is located between the air-avoiding gap 15 and the rotating hole 12, and the air-avoiding gap 15 is connected with the rotating hole 12 through the sliding groove 13. The bottom of the rotating part 11 is inserted into the liquid inlet 21, and the rotating shaft 23 passes through the air-avoiding gap 15 and the sliding groove 13 and enters the rotating hole 12, playing a role of air-avoiding. The air-avoiding gap 15 facilitates the installation of the rotating shaft 23 in the rotating hole 12 and the installation of the guide shaft 24 in the sliding groove 13.

[0032] like Figures 1 to 5 As shown, the sealing member 30 is located directly above the rotating hole 12 and is made of a soft material. When the upper cover 10 is covered with the liquid inlet 21, the sealing member 30 and the outer wall of the liquid inlet 21 form an extrusion state, and the sealing member 30 is in close contact with the outer wall of the liquid inlet 21 to form a sealed state.

[0033] In other embodiments, Figures 1 to 5 As shown, a side of the seal 30 close to the rotating part is a first inclined surface 31, and a side wall of the liquid inlet 21 close to the first inclined surface 31 is a second inclined surface 25. When the upper cover 10 is covered with the liquid inlet 21, the first inclined surface 31 is tightly fitted with the second inclined surface 25.

[0034] like Figures 1 to 5 As shown, the second inclined surface 25 also forms a gap, and when the upper cover 10 rotates, the second inclined surface 25 will not interfere with the rotation of the upper cover 10. When the upper cover 10 is covered with the liquid inlet 21, the first inclined surface 31 is tightly fitted with the second inclined surface 25. The second inclined surface 25 is inclined from the top of the liquid inlet 21 to the inner side of the bottom of the liquid inlet 21.

[0035] In other embodiments, Figures 1 to 5 As shown, a limiting boss 26 is provided in the water tank body 20 near the liquid inlet 21. When the upper cover 10 is opened relative to the liquid inlet 21 and rotated to a certain angle, the bottom of the upper cover 10 abuts against the limiting boss 26. The limiting boss 26 is located directly below the rotation connection of the upper cover 10. When the upper cover 10 is opened relative to the liquid inlet 21 and rotated to an angle of 90 degrees, the bottom of the upper cover 10 abuts against the limiting boss 26. The limiting boss 26 limits the upper cover 10 from rotating 90 degrees and then continuing to rotate. At this time, the upper cover 10 will not interfere with the liquid inlet 21.

[0036] like Figures 1 to 5 As shown, the side wall of the water storage tank body 20 is provided with a notch 27, and the notch 27 is communicated with the liquid inlet 21. The edge of the upper cover 10 is extended with an easy-opening portion 16. When the upper cover 10 is covered with the liquid inlet 21, the easy-opening portion 16 is received in the notch 27. When the upper cover 10 needs to be opened, the easy-opening portion 16 is moved so that the easy-opening portion 16 is separated from the notch 27, and the easy-opening portion 16 drives the upper cover 10 to rotate.

[0037] As Figures 1 to 5 shown, a fixing groove 17 is provided on the inner edge of the upper cover 10, and the inner side wall of the seal 30 is injection-molded or inlaid in the fixing groove 17. The seal 30 is firmly fixed to the upper cover 10, and the sealing performance between the seal 30 and the upper cover 10 is good.

[0038] Second embodiment, as Figures 1 to 6 shown, a dental irrigator includes a dental irrigator nozzle 40, a dental irrigator body 50, a driving pump, and the leak-proof water storage tank described above. The driving pump is used to extract water from the water storage tank and spray it out from the dental irrigator nozzle 40. The driving pump is arranged in the dental irrigator body 50, and the leak-proof water storage tank is arranged in the dental irrigator body 50. The water storage tank is used for storing water, and the driving pump is used to extract water from the water storage tank and spray it out from the dental irrigator nozzle 40.

[0039] The above are the specific embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present invention.
