Description

Technical Field

[0001] This utility model belongs to the field of cleaning appliance technology, and in particular relates to a locking structure for the bottom cover of a vacuum cleaner dust cup that prevents it from detaching. Background Technology

[0002] Cleaning appliances are electrical appliances used to clean items and indoor environments. With the improvement of modern economic level, cleaning appliances have also entered people's lives. As the use of cleaning appliances becomes more frequent, people's requirements for the ease of operation of cleaning appliances are also constantly increasing.

[0003] Existing vacuum cleaner dust cup bottom covers typically use a locking button to engage with the dust cup, but the button lacks an anti-detachment mechanism. Accidentally pressing the button can easily open the dust cup bottom cover, causing dust to fall out of the dust cup. Utility Model Content

[0004] The purpose of this utility model is to provide a dust cup bottom cover locking structure that prevents dust from falling out of the dust cup due to accidental activation of the release button.

[0005] To achieve the above objectives, this utility model provides a lock structure for an anti-detachment dust cup bottom cover of a vacuum cleaner, which includes:

[0006] A locking hook is fixedly connected to the bottom cover of the dust cup, and the end of the bottom cover of the dust cup away from the locking hook is hinged to the dust cup. A first inclined surface is provided on the locking hook.

[0007] A button assembly is rotatably connected to the dust cup. The button assembly has a second inclined surface. When the locking hook engages with the locking seat on the dust cup, the part of the button assembly that contacts the locking hook is located below the locking hook, and the first inclined surface abuts against the second inclined surface.

[0008] As a further description of the above technical solution:

[0009] The button assembly includes a button and a spring. The button is rotatably connected to the dust cup. One end of the button is connected to the spring. A second inclined surface is disposed at the end of the button away from the spring. One end of the second inclined surface has a horizontal plate, and the top of the horizontal plate abuts against the locking hook.

[0010] As a further description of the above technical solution:

[0011] The dust cup is provided with a mounting groove, the button is located in the mounting groove, and connecting plates are provided on both sides of the button, with a rotating shaft on the connecting plates.

[0012] As a further description of the above technical solution:

[0013] The bottom cover of the dust cup is provided with a first slot, and a first elastic sealing ring is provided in the first slot to abut against the end of the dust cup.

[0014] As a further description of the above technical solution:

[0015] The first elastic sealing ring is provided with a limiting groove, and the dust cup is provided with a limiting plate that matches the limiting groove.

[0016] As a further description of the above technical solution:

[0017] The dust cup bottom cover is provided with a second slot, and a second elastic sealing ring is provided in the second slot.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: by setting the first and second inclined surfaces, when the locking hook hooks onto the locking seat on the dust cup, the part of the button assembly that contacts the locking hook is located below the locking hook, and the first inclined surface abuts against the second inclined surface. In this way, the first inclined surface can apply a downward pressure to the second inclined surface, thereby making it difficult for the button to push up the locking hook, and making the bottom cover of the dust cup more stable.

[0032] Please see Figure 1-5This utility model provides a locking structure for the bottom cover of a vacuum cleaner dust cup that prevents it from detaching, including:

[0033] The locking hook 1 is fixedly connected to the dust cup bottom cover 2. The end of the dust cup bottom cover 2 away from the locking hook 1 is hinged to the dust cup 17. The locking hook 1 is provided with a first inclined surface 3.

[0034] Button assembly 4 is rotatably connected to the dust cup 17. The button assembly 4 is provided with a second inclined surface 5. When the locking hook 1 hooks the locking seat 6 on the dust cup 17, the part of the button assembly 4 that contacts the locking hook 1 is located below the locking hook 1, and the first inclined surface 3 abuts against the second inclined surface 5.

[0035] The button assembly 4 includes a button 41 and a spring 42. The button 41 is rotatably connected to the dust cup 17, and one end of the button 41 is connected to the spring 42. A second inclined surface 5 is disposed at the end of the button 41 away from the spring 42. One end of the second inclined surface 5 has a horizontal plate 7, and the top of the horizontal plate 7 abuts against the locking hook 1. In use, pressing one end of the button spring causes the horizontal plate to tilt upward, thereby lifting the locking hook and disengaging it from the locking seat, allowing the dust cup bottom cover to be opened to empty the dust inside the dust cup.

[0036] The dust cup 17 is provided with a mounting groove 8, and the button 41 is located in the mounting groove 8. Connecting plates 9 are provided on both sides of the button 41, and a rotating shaft 10 is provided on the connecting plate 9. The button is rotatably connected to the dust cup through the rotating shaft. After the spring returns to its original position, the bottom of the connecting plate abuts against the bottom of the mounting groove.

[0037] The dust cup bottom cover 2 is provided with a first slot 11, and a first elastic sealing ring 12 is provided in the first slot 11 to abut against the end of the dust cup 17. The first elastic sealing ring 12 is provided with a limiting groove 13, and the dust cup 17 is provided with a limiting plate 14 that matches the limiting groove 13. This improves the sealing effect.

[0038] The dust cup bottom cover 2 is provided with a second slot 15, and a second elastic sealing ring 16 is provided in the second slot 15. The second slot is located inside the first slot, and the second elastic sealing ring can abut against the support of the cyclone cone inside the dust cup. The first elastic sealing ring and the second elastic sealing ring, together with the locking hook, can make the dust cup bottom cover more stable.

[0039] Working principle: With the first and second inclined surfaces, when the locking hook engages with the locking seat on the dust cup, the part of the button assembly that contacts the locking hook is located below the locking hook. The first inclined surface abuts against the second inclined surface, so that the first inclined surface can apply a downward pressure to the second inclined surface, thereby making it less likely for the button to push up the locking hook and making the bottom cover of the dust cup more stable.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
