Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning appliances, in particular to a rotating float water level protection mechanism. BACKGROUND

[0002] The existing lifting type float structure is closed to the suction inlet of the machine and slowly sticks to the suction inlet according to the rising of the liquid level surface, so as to achieve the purpose of blocking the suction inlet and preventing the motor from sucking water. However, when the suction inlet is slowly reduced, the product suction force will continue to increase. In this case, the buoyancy of the float cannot resist the suction force, so that the float sticking surface stops moving upward before the suction inlet is stuck, thereby causing the motor to be unable to be protected. SUMMARY

[0041] Example 1:

[0042] Please see Figs. 1-6 The present invention provides a rotating float water level protection mechanism, comprising:

[0043] Water tank 1, wherein a suction port 2 is provided on the water tank 1;

[0044] The float 3 includes a float body 31, a connecting plate 32, and a baffle 33. The float body 31 has a cavity 4. A baffle 33 is fixedly connected to one end of the float body 31. A connecting plate 32 is provided on both sides of the baffle 33. A rotating shaft 5 is fixedly connected to the connecting plate 32. The float 3 is rotatably connected to the water tank 1 through the rotating shaft 5. The baffle 33 can abut against the suction port 2.

[0045] Specifically, a hollow connecting column 6 is provided inside the water tank 1, and the suction port 2 is located at the top of the connecting column 6. The connecting column is fixedly connected to the water tank and is located in the middle of the water tank. During operation, liquid enters the water tank through the connecting column.

[0046] Specifically, a mounting part 7 is provided on one side of the inlet 2. The mounting part 7 is fixedly connected to the connecting column 6, and a float seat 8 is provided on the mounting part 7. The rotating shaft 5 is rotatably connected to the float seat 8. The mounting part is fixedly connected to the connecting column, and the connecting part is hemispherical, which facilitates the installation and removal of the float seat on the connecting part.

[0047] Specifically, a rotating connection part 14 is provided on the float base 8. The rotating connection part 14 is located at the bottom of one end of the float base 8. A shaft hole 15 is provided on the rotating connection part 14, and the rotating shaft 5 is rotatably connected in the shaft hole 15. The connection part is U-shaped, which can ensure the smooth rotation of the float.

[0048] Specifically, a bottom cover 16 is provided at the end of the float body 31 away from the baffle 33, and the bottom cover 16 is fastened to the float body 31. The bottom cover 16 has a concave arc-shaped surface 161.

[0049] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0050] The float is rotatably connected to the connecting column inside the water tank via a rotating shaft. One end of the float cavity floats on the liquid surface. As the liquid level rises, the float rotates around the rotating shaft, meaning one end of the float cavity moves upward and the other end of the abutment plate moves downward. The angle between the baffle and the suction port gradually decreases. When it decreases to a certain extent, the baffle instantly fits against the suction port, closing the suction port. At this point, the product has no suction at the cleaning end, thus protecting the motor from over-suction.

[0051] Example 2:

[0052] See Figs. 1-6 The figure shows a rotating float water level protection mechanism provided by Embodiment 2 of the present invention. This embodiment further improves upon the previous embodiment by making the following technical improvements: the float seat 8 is inserted into the mounting part 7, and the float seat 8 is provided with a through hole 9, which faces the suction port 2. The through hole is adapted to the size of the suction port, and the float seat has a cavity that matches the mounting part, allowing for a tighter fit between the float seat and the mounting part.

[0053] Example 3:

[0054] See Figs. 1-6 The figure shows a rotating float level protection mechanism provided by Embodiment 3 of the present invention. This embodiment further improves upon the previous embodiments by providing the following technical solution: A first screw hole 10 is provided on the float seat 8, and a screw 11 passes through the first screw hole 10. The screw 11 passes through the first screw hole 10 and is screwed into a second screw hole 12 on the mounting part 7. The second screw hole is located on the spherical surface of the mounting part. By using a screw to further tighten the float seat, the float seat can be more firmly fixed.

[0055] Example 4:

[0056] See Figs. 1-6The figure shows a rotating float water level protection mechanism provided by Embodiment 4 of the present invention. This embodiment further improves upon the previous embodiments by providing the following technical solutions: The float seat 8 is provided with an abutment surface 13, and the baffle 33 is provided with an abutment plate 34, which abuts against the abutment surface 13. The abutment plate is perpendicular to the baffle. When the baffle is in contact with the suction port, the abutment plate abuts against the abutment surface, thereby restricting the rotation of the float and ensuring the baffle is tightly fitted to the suction port, improving the sealing effect. Sealing cotton 341 is provided on the abutment plate 34. The sealing cotton is adhered to the abutment plate, further tightening the seal between the float and the sewage tank.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
