Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, in particular to a HEPA cleaning device for vacuum cleaners. Background Art

[0002] At present, the dust barrel of a vacuum cleaner mainly includes a main body, a dust cup installed at the front of the main body and a dust suction motor installed in the main body, and the dust suction motor provides dust suction wind force into the dust cup; when working, the dust cup sucks in dust, garbage and other debris through the dust suction port, and large particles of dust, garbage, etc. are filtered by the filter and directly stored in the outer dust chamber, and small particles of dust that cannot be filtered by the filter enter the inner dust chamber and are filtered and blocked outside the HEPA tube. After being used for a period of time, a lot of small particles of dust will adhere to the outer surface of the HEPA tube, which greatly affects the filtering efficiency of the HEPA tube and reduces the service life of the HEPA tube. At this time, the cup cover must be opened to take out the HEPA tube for cleaning and reloading. This not only brings inconvenience to the cleaning of the HEPA tube, but also requires cleaning the HEPA tube after a very short period of use, which also reduces the effective use time of the vacuum cleaner.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Embodiment 1: This embodiment provides a vacuum cleaner HEPA cleaning device, see Figure 1-3 Specifically, it includes a main body, a reduction motor 11 is provided in the main body, a scraper assembly 12 is fixedly provided at the output end of the reduction motor 11, a main body 1 and a dust bucket 3 are provided in the main body, a plurality of scraper pieces 13 are inserted on the scraper assembly 12, the scraper assembly 12 body is made of a trident-shaped metal material, the scraper piece 13 is made of rubber material, the scraper piece 13 fits with the inner and outer walls of the filter assembly, a main motor 4 is provided on the main body 1, a HEPA cleaning assembly is provided in the main body 1, the HEPA cleaning assembly is located at the lower edge of the main body 1 and inside the dust bucket 3, the HEPA cleaning assembly includes a reduction motor upper cover 2, and the reduction motor upper cover 2 is fixedly connected to the upper end of the reduction motor 11.

[0018] The reduction motor 11 is fixed by the reduction motor upper cover 2. The reduction motor 11 can be installed on the inside or outside of the HEPA. The scraper assembly 12 is placed in any position that can be driven by the reduction motor 11. The scraper assembly 12 is driven to rotate by the reduction motor 11. The scraper member 13 on the scraper assembly 12 contacts the filter HEPA member 32. The dirt adsorbed by the filter HEPA member 32 falls down through the vibration of the cleaning. The scraper member 13 avoids damage to the filter HEPA member 32. The reduction motor 11 can also be arbitrarily set at any position in the main body 1.

[0019] Embodiment 2: Based on Embodiment 1, this embodiment further includes:
