Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum cleaners, in particular to a vacuum cleaner which is convenient for replacing filter elements. Background Art

[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. The working principle of a vacuum cleaner is that the fan impeller of the vacuum cleaner is driven at high speed by the motor to discharge the air in the impeller out of the fan at high speed, while the air in the dust collection part is continuously replenished into the fan. This may form a higher pressure difference with the outside world, and the dust and dirt in the suction nozzle are sucked into the dust collection part along with the air, and filtered by the filter element, and the dust and dirt are collected in the dust cylinder.

[0003] The existing patent publication number CN219813993U discloses a vacuum cleaner filter element that is easy to replace, including an air suction machine, and the input end of the air suction machine is fixedly connected to an air inlet pipe. The utility model can realize that during use, by starting the air suction machine to evacuate the storage shell, the dust is sucked into the storage shell by suction. During the adsorption process, the filter element filters the impurities sucked into the air inlet pipe. When the filter element is removed, the connection block and the plug interface in the filter element are limited by the elastic structure. During removal, the filter element will rotate in the same direction as the storage shell, and the filter element and the storage shell are removed at the same time, reducing the process of removing the filter element separately after removing the storage shell. During removal, the filter element is directly removed in the storage shell, and the storage box and the filter element are directly and uniformly cleaned, reducing the secondary pollution caused by dust falling when the filter element is removed separately after the storage shell is removed, thereby increasing the practicality of the structure.

[0004] Although the above-mentioned vacuum cleaner filter element is easy to disassemble, the filter element must also be disassembled when the storage box is disassembled. When only the storage box needs to be cleaned, the filter element is installed in the storage box, which will hinder the cleaning of the storage box. The filter element needs to be disassembled again, and the operation is relatively cumbersome. When cleaning, since the dust is on the outside of the filter element, the dust on the surface of the filter element may fall off during the process of taking out the filter element, which again affects the environment.

[0005] Therefore, it is desirable to provide a vacuum cleaner that is convenient for filter cartridge replacement. Utility Model Content

[0020] 1. The utility model provides a vacuum cleaner that is easy to replace the filter element. The vacuum cleaner arranges the filter element body in the dust storage box and fixes it to the inner wall of one end of the connecting pipe through a fixing structure. The external thread of the connecting pipe is connected to the dust storage box. When the dust storage box only needs to be cleaned, the dust storage box can be disassembled separately.

At this time, the filter element body can be taken out, and disassembly is convenient.

[0022] 3. The utility model provides a cleaning structure at one end of the filter element body. Before disassembling the filter element body, the motor in the cleaning structure drives the rotating shaft and the cleaning brush to rotate. The cleaning brush rotates along the side wall of the filter element body to clean the dust on the outer wall of the filter element body and sweep the dust into the dust storage box. This avoids the dust on the surface of the filter element body falling when the filter element body is taken out, which affects the environment again. During the use of the vacuum cleaner, the dust on the surface of the filter element body is cleaned by the cleaning structure, which avoids clogging of the filter element body and reduces the frequency of disassembly and cleaning of the filter element body.
