Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, and in particular relates to a linkage structure for the simultaneous unlocking of the dust cup bottom cover and the scraping of dust by the filter assembly in a vacuum cleaner. Background Technology

[0002] A vacuum cleaner works by using the high-speed rotation of an electric motor to extract air from the dustbin, creating a partial vacuum. Outside the dustbin, due to air pressure, dust and other dirt are drawn in along with the air into the filter or dust bag inside the dustbin, while the filtered air is then expelled from the vacuum cleaner.

[0003] However, as a crucial component of vacuum cleaners, the dust cup filter's frequent dust accumulation directly impacts the overall cleaning performance. When a large amount of dust accumulates on the outside of the dust cup filter, it not only obstructs airflow and reduces suction power but also causes internal blockages, significantly diminishing its cleaning effectiveness. Furthermore, the dust on the outside of the dust cup filter can become a breeding ground for bacteria, posing a potential threat to household hygiene. Cleaning it requires disassembling the dust cup each time, a cumbersome process that also shortens the vacuum cleaner's lifespan. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that dust on the outside of the existing dust cup filter can become a breeding ground for bacteria, posing a potential threat to the hygiene of the home environment. Each time it is cleaned, the dust cup must be disassembled, which is cumbersome and affects the service life of the vacuum cleaner. Therefore, a linkage structure is proposed to unlock the bottom cover of the vacuum cleaner dust cup and scrape off the dust.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a linkage structure for unlocking the bottom cover of the dust cup of a vacuum cleaner and scraping dust from the filter assembly, comprising a vacuum cleaner body, the vacuum cleaner body including a motor assembly and a dust cup assembly, the motor assembly including a motor, a motor housing and a guide housing, the dust cup assembly including a filter assembly and a dust cup housing, a handle seat provided on the vacuum cleaner body, the dust cup assembly abutting against the handle seat, a dust scraping ring cylinder movably sleeved on the filter assembly, a sliding button provided on the handle seat, the sliding button connected to a pull plate, the pull plate connected to a guide ring, and the guide ring connected to the dust scraping ring cylinder.

[0006] As a further description of the above technical solution:

[0007] A tie rod is provided between the scraper ring cylinder and the guide ring.

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

[0009] The handle base has guide grooves on both sides, and the sliding button can be slidably connected in the guide grooves.

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

[0011] The guide shell is provided with a plurality of guide ribs, and the inner wall of the guide ring matches the guide ribs.

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

[0013] The sliding button is equipped with a push plate.

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

[0015] The pull plate is provided with an abutment block, and a spring is provided between the abutment block and the dust cup shell.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, a scraping ring cylinder is installed outside the filter assembly inside the dust cup. This ring cylinder and the guide ring on the guide shell inside the motor assembly are linked together via a pull plate. The pull plate is connected to a sliding button. When it is necessary to clean the outside of the filter assembly in the dust cup, simply push the push plate, which will move the sliding button and thus the pull plate. This allows the scraping ring cylinder to scrape the outside of the filter assembly and clean its exterior without disassembling the dust cup. After scraping is completed, the pull plate automatically resets under the action of a spring. This structure is simple to operate and highly practical. Attached Figure Description

[0031] Please see Figure 1-4 This utility model provides a technical solution: a linkage structure for unlocking the bottom cover of the dust cup of a vacuum cleaner and scraping dust from the filter assembly, comprising a vacuum cleaner body 1, the vacuum cleaner body 1 including a motor assembly 2 and a dust cup assembly 3, the motor assembly 2 including a motor 21, a motor housing 22 and a guide housing 23, the dust cup assembly 3 including a filter assembly 31 and a dust cup housing 32, a handle seat 4 provided on the vacuum cleaner body 1, the dust cup assembly 3 abutting against the handle seat 4, a dust scraping ring cylinder 5 movably sleeved on the filter assembly 31, a sliding button 6 provided on the handle seat 4, the sliding button 6 connected to a pull plate 7, the pull plate 7 connected to a guide ring 8, and the guide ring 8 connected to the dust scraping ring cylinder 5.

[0032] A pull rod 9 is provided between the scraper ring cylinder 5 and the guide ring 8.

[0033] The handle base 4 has guide grooves 10 on both sides, and the sliding button 6 is slidably connected in the guide grooves 10. By sliding the sliding button along the guide groove, the pull plate can be pulled, thereby driving the scraper cylinder to scrape dust from the filter assembly.

[0034] The guide shell 23 is provided with a plurality of guide ribs 11, and the inner wall of the guide ring 8 matches the guide ribs 11. This guides the guide ring, prevents it from rotating, and improves the efficiency of dust removal.

[0035] The sliding button 6 is equipped with a push plate 12.

[0036] The pull plate 7 is equipped with an abutment block 13, and a spring is installed between the abutment block 13 and the dust cup shell 32. When the abutment block abuts against the inner wall of the dust cup shell, the pull plate stops moving, realizing the cleaning of the outside of the filter assembly. After the cleaning is completed, the abutment block automatically resets under the action of the spring, and the pull plate drives the scraper ring cylinder and guide ring to retract, which is highly practical.

[0037] Working principle: A scraping ring cylinder is installed outside the filter assembly inside the dust cup. It is linked to the guide ring on the guide shell inside the motor assembly via a pull plate. The pull plate is connected to a sliding button. When it is necessary to clean the outside of the filter assembly in the dust cup, simply push the push plate, which will move the sliding button and thus the pull plate. This allows the scraping ring cylinder to scrape the outside of the filter assembly and clean the exterior of the filter assembly without disassembling the dust cup. After the scraping is completed, the pull plate automatically resets under the action of a spring. This structure is simple to operate and highly practical.

[0038] 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.
