Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, and in particular relates to a leak-proof structure for the air inlet filter of a vacuum cleaner. Background Technology

[0002] While vacuum cleaners on the market today are versatile and efficient, they share a common problem in daily use: after removing and cleaning the air intake filter, users often neglect to reinstall it. This seemingly minor oversight can actually lead to serious consequences—when a vacuum cleaner without an air intake filter is in operation, external dust and fine particles will freely enter the motor, quickly accumulating and causing a decline in motor performance, potentially leading to motor wear or even damage, ultimately shortening the vacuum cleaner's lifespan. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the air inlet filter of a vacuum cleaner is easily forgotten after being removed and cleaned, which leads to dust entering the motor during use, causing machine damage and affecting its service life. Therefore, this utility model proposes a leak-proof structure for the air inlet filter of a vacuum cleaner.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a leak-proof structure for a vacuum cleaner air inlet filter, comprising:

[0005] The vacuum cleaner body includes a base, a handle housing, and a motor component, wherein the handle housing is connected to the base, and the motor component is connected to the handle housing;

[0006] The dust cup assembly includes a dust cup and an air inlet filter. The air inlet filter is located inside the dust cup. The top of the air inlet filter is connected to the motor component. The bottom of the dust cup is provided with a bottom cover, and the bottom cover is provided with a through hole. The bottom of the air inlet filter is sealed against the through hole.

[0007] As a further description of the above technical solution:

[0008] The motor component includes a housing, a motor, and a guide tube. The motor is located inside the housing, the guide tube is connected to the motor, and the guide tube extends into the air inlet filter.

[0009] As a further description of the above technical solution:

[0010] The handle housing has an inner groove, and the dust cup side end abuts against the groove.

[0011] As a further description of the above technical solution:

[0012] A limiting ring is provided at the bottom of the housing, and a limiting groove is provided at the top of the air inlet filter. The limiting groove and the limiting ring are matched.

[0013] As a further description of the above technical solution:

[0014] The housing is provided with a slot, and the dust cup is provided with a block, which matches the slot.

[0015] As a further description of the above technical solution:

[0016] A rubber ring is provided at the bottom of the air inlet filter element, and the rubber ring abuts against the inner wall of the through hole.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] In this invention, by opening a ventilation hole in the bottom cover of the dust cup, the air inlet filter must be installed inside the dust cup during use, ensuring that the sealing ring at the bottom of the air inlet filter abuts against the inner wall of the through hole. This guarantees that the vacuum cleaner can be used normally. If the air inlet filter is forgotten to be installed, the vacuum cleaner will leak air, resulting in no suction power and rendering the machine unusable. This solves the risk of foreign objects being sucked into the motor when the vacuum cleaner is turned on if the air inlet filter is forgotten, thus improving the service life of the vacuum cleaner.

[0031] Please see Figure 1-3 This utility model provides a technical solution: a leak-proof structure for the air inlet filter of a vacuum cleaner, comprising:

[0032] The vacuum cleaner body 1 includes a base 11, a handle shell 12, and a motor component 13. The handle shell 12 is connected to the base 11, and the motor component 13 is connected to the handle shell 12.

[0033] The dust cup assembly 2 includes a dust cup 21 and an air inlet filter 22. The air inlet filter 22 is located inside the dust cup 21. The top of the air inlet filter 22 is connected to the motor component 13. The bottom of the dust cup 21 is provided with a bottom cover 3. The bottom cover 3 is provided with a through hole 4. The bottom of the air inlet filter 22 is sealed against the through hole 4.

[0034] The motor component 13 includes a housing 131, a motor 132, and a guide tube 133. The motor 132 is located inside the housing 131, and the guide tube 133 is connected to the motor 132 and extends into the air inlet filter 22.

[0035] The handle housing 12 has an inner groove 5, and the dust cup 21 abuts against the groove 5.

[0036] A limiting ring 6 is provided at the bottom of the housing 131, and a limiting groove is provided at the top of the air inlet filter 22. The limiting groove and the limiting ring 6 are matched. This improves the stability of the air inlet filter when installed on the vacuum cleaner.

[0037] The housing 131 is provided with a slot 9, and the dust cup 21 is provided with a locking block 7, which matches the slot 9. This improves the stability of the dust cup installation.

[0038] A rubber ring 8 is provided at the bottom of the air inlet filter 22, and the rubber ring 8 abuts against the inner wall of the through hole 4. This improves the sealing of the dust cup installation and prevents air leakage from the vacuum cleaner.

[0039] Working principle: By opening a vent in the bottom cover of the dust cup, the vacuum cleaner must have the air inlet filter installed inside the dust cup during use. The sealing ring at the bottom of the air inlet filter must abut against the inner wall of the vent to ensure the vacuum cleaner can work properly. If the air inlet filter is not installed, the vacuum cleaner will leak air, resulting in no suction power and making the machine unusable. This solves the risk of foreign objects being sucked into the motor when the vacuum cleaner is turned on if the air inlet filter is not installed, thus extending the service life of the vacuum cleaner.

[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.
