Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically a manual cleaning structure for a vacuum cleaner filter. Background Technology

[0002] The existing methods for cleaning vacuum cleaner filters have significant drawbacks. Most products require disassembling the dust cup and separating the filter, followed by cleaning through tapping, washing, or using additional tools, a process that is cumbersome and time-consuming. Even in models with a simple cleaning function, the cleaning mechanism and dust cup opening mechanism are independent, requiring separate opening and cleaning actions, which is inconvenient.

[0003] Meanwhile, the disassembly and cleaning process can easily generate secondary dust, polluting the environment and affecting users' health. If cleaning is not done in time, dust, hair, fibers and other dirt adhering to the filter surface will clog the filter holes, causing obstructed airflow and a significant decrease in suction efficiency. Long-term accumulation can also cause the suction motor to overheat, severely shortening the vacuum cleaner's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a manual cleaning structure for vacuum cleaner filters, so as to solve the problem of cumbersome filter cleaning in the above-mentioned background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A manual cleaning structure for a vacuum cleaner filter includes a vacuum cleaner body and a dust cup assembly disposed on the vacuum cleaner body. A ring-shaped filter is fixedly mounted on the dust cup assembly, and a manual dust scraping mechanism is provided on the dust cup assembly for scraping off at least part of the dirt on the surface of the ring-shaped filter. The manual scraping mechanism includes a ring-shaped support, a scraper, a connecting rod, a moving plate, and a handle; The annular support is configured as an annular structure adapted to the annular filter screen and is sleeved on the outside of the annular filter screen. A connecting rod is fixedly installed on one side of the bottom of the annular bracket, and the end of the connecting rod away from the annular bracket is fixedly connected to the movable plate; The dust cup assembly housing has a strip-shaped through hole, and the handle fixed on the moving plate extends to the outside of the housing through the strip-shaped through hole.

[0006] In a preferred embodiment of this utility model, a scraper is fixedly installed on the inner side wall of the annular bracket, and the inner edge of the scraper is in contact with the outer peripheral surface of the annular filter screen.

[0007] In a preferred embodiment of this utility model, the movable plate is slidably connected to the inside of the dust cup assembly housing.

[0008] In a preferred embodiment of this utility model, a spring positioning post is fixedly installed on the movable plate, and a spring is sleeved on the outer wall of the spring positioning post.

[0009] In a preferred embodiment of this utility model, one end of the spring abuts against the stepped surface of the spring positioning post, and the other end is fixedly connected to the inner wall of the dust cup assembly housing.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figure 1-6 A manual cleaning structure for a vacuum cleaner filter includes a vacuum cleaner body 100 and a dust cup assembly disposed on the vacuum cleaner body 100. An annular filter 150 is fixedly mounted on the dust cup assembly to intercept dust, hair and other impurities in the airflow. The dust cup assembly includes a housing, with an internal space for receiving the suction motor, which generates a negative pressure suction airflow. A battery pack is detachably installed on the outside of the vacuum cleaner body 100. The battery pack powers the suction motor and contains a circuit board and a controller. The circuit board and controller output signals to control the start, stop, and speed of the suction motor. The above structure is common in the prior art and will not be described in detail here. The dust cup assembly is equipped with a manual dust scraping mechanism for scraping off at least part of the dirt on the surface of the annular filter screen 150.

[0020] The manual scraping mechanism includes a ring-shaped support 210, a scraper 220, a connecting rod 230, a moving plate 240, and a handle 250. The annular support 210 is an annular structure adapted to the annular filter 150 and is sleeved on the outside of the annular filter 150. A scraper 220 is fixedly installed on the inner wall of the annular bracket 210. The scraper 220 is made of elastic rubber or nylon. The inner edge of the scraper 220 is closely attached to the outer circumferential surface of the annular filter screen 150 to scrape off dirt attached to the surface. A connecting rod 230 is fixedly installed on one side of the bottom of the ring bracket 210, and the end of the connecting rod 230 away from the ring bracket 210 is fixedly connected to the movable plate 240. The movable plate 240 is slidably connected to the inside of the dust cup assembly housing, and the sliding is ensured to be smooth by the cooperation of the slide rail and the slider; The dust cup assembly housing has a strip-shaped through hole 140, and the handle 250 fixed on the moving plate 240 extends to the outside of the housing through the strip-shaped through hole 140 for the user to push manually.

[0021] A spring positioning post 260 is fixedly installed on the movable plate 240, and a spring 270 is sleeved on the outer wall of the spring positioning post 260. One end of spring 270 abuts against the stepped surface of spring positioning post 260, and the other end is fixedly connected to the inner wall of the dust cup assembly housing; The spring positioning pin 260 cooperates with the spring 270 to achieve automatic elastic reset after the handle 250 is pushed, without the need for manual reset by the user.

[0022] The annular filter screen 150 has a cylindrical annular structure. The sides of the annular filter 150 are covered with filter holes, or filter holes are set only in a part of the surface area according to the filtration requirements. After the airflow enters the dust cup through the air inlet, it is filtered by the annular filter 150. The filtered airflow flows out of the dust cup assembly or enters the next stage of filtration structure (such as a HEPA filter).

[0023] The working principle of this utility model is as follows: Cleaning process for ring filter screen: After using the vacuum cleaner, dust, hair, and other dirt accumulate on the outer periphery of the ring filter 150, requiring cleaning. The user holds the vacuum cleaner body 100 with one hand and pinches the handle 250 extending to the outside of the outer shell with the other hand, and slowly pushes it along the axial direction (usually vertical) of the strip-shaped through hole 140. The handle 250 drives the movable plate 240 to slide along the slide rail inside the housing. The movable plate 240 drives the annular bracket 210 to move synchronously through the connecting rod 230. The scraper 220 on the inner side of the annular bracket 210 slides relative to the outer circumference of the annular filter screen 150. The inner edge of the scraper 220 scrapes off the dirt attached to the filter screen. The dirt falls to the dust collection area at the bottom of the dust cup under the action of gravity.
