A cleaning linkage structure for the filter component inside the dust cup

Abstract

This utility model discloses a cleaning linkage structure for a filter assembly inside a dust cup, belonging to the field of vacuum cleaner technology. It includes a dust cup containing a filter screen, a scraper ring on the rear side of the filter screen, and a linkage ear on the scraper ring. A limit shell is provided on the outer shell of the dust cup. A push button passes through the limit shell and connects to a linkage plate. The linkage plate and the linkage ear are connected by a push rod. This utility model, by setting a scraper ring on the filter screen, a linkage ear on the scraper ring, a limit shell on the outer shell of the dust cup, and a push button passing through the limit shell and connecting to the linkage plate, and the linkage plate and linkage ear connected by a push rod, allows for easy cleaning of the filter screen by simply pulling the push button. This push button moves the linkage plate, which in turn moves the connecting plate. The push rod then pushes the linkage ear, causing the scraper ring to scrape dust off the filter screen surface. This structure eliminates the need to disassemble the filter screen for cleaning, improving filter screen cleaning efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, and in particular relates to a cleaning linkage structure for the filter component inside the dust cup. Background Technology

[0002] A vacuum cleaner is a household appliance that uses an electric motor to drive blades to rotate at high speed, creating negative air pressure within a sealed casing to suck up dust and debris. It is widely used in homes, offices, factories, and other places to clean dust and debris from surfaces such as floors, carpets, furniture, and curtains, greatly improving cleaning efficiency and reducing the burden of manual cleaning.

[0003] Currently, the filters inside the dust cup of vacuum cleaners easily accumulate a large amount of dust and debris during long-term use. If not cleaned in time, this will significantly reduce the suction power of the vacuum cleaner, affecting its overall performance and cleaning effect. Therefore, regular cleaning is necessary. However, cleaning the filter is not an easy process. It usually requires the user to manually remove the filter from the dust cup. Because the filter structure is often quite delicate and the connection between it and the dust cup is complex, frequent disassembly not only increases the difficulty and time cost for the user, but also easily leads to wear, loosening, or even damage to the clips, seals, and other components of the filter or dust cup. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that vacuum cleaners need to be cleaned regularly. Users manually remove the filter from the dust cup. Since the filter structure is often quite delicate and the connection with the dust cup is complex, frequent disassembly not only increases the user's operating difficulty and time cost, but also easily leads to wear, loosening or even damage to the clips, sealing rings and other parts of the filter or dust cup. Therefore, a dust cup filter component cleaning linkage structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust cup internal filter component cleaning linkage structure, including a dust cup, a filter screen is provided inside the dust cup, a scraper ring is provided on the rear side of the filter screen, a linkage ear is provided on the scraper ring, a limit shell is provided on the outer shell of the dust cup, a push button passes through the limit shell and is connected to a linkage plate, and the linkage plate and the linkage ear are connected by a push rod.

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

[0007] The bottom of the dust cup is connected to the dust inlet pipe and communicates with the outlet of the dust inlet pipe.

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

[0009] The dust cup is snapped onto the main unit of the vacuum cleaner at its rear end.

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

[0011] The limiting shell is provided with a sliding groove, the push button passes through the sliding groove and is connected to the linkage plate, the dust cup shell is provided with a limiting head, the limiting head is provided with a guide rod, a spring is sleeved on the outside of the guide rod, the spring is located inside the linkage plate, and the linkage plate is slidably connected to the limiting head.

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

[0013] The linkage plate is provided with a telescopic groove. One end of the spring is connected to the inner wall of the telescopic groove, and the other end is connected to the limiting head. One end of the guide rod is fixedly connected to the limiting head. The end of the linkage plate is provided with a through hole, and the other end of the guide rod extends into the through hole.

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

[0015] A connecting plate is provided on the linkage plate, and a moving groove is provided on the dust cup. The moving groove forms a connecting platform on the outer wall of the dust cup. The linkage ear is movably connected to the moving groove. One end of the push rod is connected to the connecting plate, and the other end passes through the connecting platform and is connected to the linkage ear.

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

[0017] 1. In this utility model, a scraping ring is set on the filter screen, and a linkage ear is set on the scraping ring. A limiting shell is set on the dust cup shell. A push button passes through the limiting shell and is connected to the linkage plate. The linkage plate and the linkage ear are connected by a push rod. When it is necessary to scrape dust off the filter screen, simply pull the push button, so that the push button drives the linkage plate, the linkage plate drives the connecting plate to move, and the push rod pushes the linkage ear, so that the scraping ring scrapes dust off the surface of the filter screen. This structure eliminates the need to disassemble the filter screen for cleaning, thus improving the efficiency of filter screen cleaning.

[0018] 2. In this utility model, a guide rod is provided on the limiting head, and a spring is sleeved on the outside of the guide rod. The spring is located inside the linkage plate. When the push button needs to be pulled, one end of the spring inside the linkage plate abuts against the telescopic groove, and the other end abuts against the limiting head. Pushing the button moves the linkage plate and moves it on the limiting head. The other end of the guide rod extends out from the through hole, thereby completing the movement of the linkage plate and pushing the push rod to move, so as to drive the scraper ring to scrape the filter screen.
