Description

Technical Field

[0001] The utility model relates to the technical field of air disinfection machines, in particular to a novel composite air purification and sterilization device. Background Art

[0002] An air disinfector is a machine that disinfects the air through the principles of filtration, purification, and sterilization. In addition to killing bacteria, viruses, mold, spores and other so-called sterilization and disinfection, some models can also remove formaldehyde, phenol and other organic pollutants in indoor air, and can also kill or filter allergens such as pollen. At the same time, it can effectively remove smoke and smoke produced by smoking, bad odors in the bathroom, human body odor, etc. The disinfection effect is reliable, and it can be disinfected when there are people active, realizing the coexistence of man and machine.

[0003] There are many types of air disinfectors due to their diverse principles, but the main types are plasma air disinfectors and ultraviolet air disinfectors. Among them, the plasma air disinfector uses a super-energy ion generator to instantly excite trillions of positive and negative ions, which can effectively kill bacteria. The plasma sterilization effect is extremely strong and the action time is short. When the plasma air disinfector is actually used, a high-efficiency composite filter and a primary filter are arranged from the inside to the outside at the air inlet of the super-energy ion generator. The primary filter is mainly used to filter and intercept impurities such as dust and lint in the air. Due to the high frequency of daily use of the plasma air disinfector, the surface of the primary filter is very likely to reduce the ventilation rate due to the adhesion of impurities, which is not conducive to the long-term and stable use of the plasma air disinfector. Based on this, a new type of composite air purification and sterilization device is provided. Utility Model Content

[0036] The inner cavity and the bottom of the outer case 101 are provided with a self-cleaning component 3, which is used to clean and collect impurities on the surface of the primary filter 206;

[0037] The self-cleaning assembly 3 includes a cleaning cylinder 301, a brush 302, a suction port 303, a collection box 304, and a material drop chute 305;

[0038] The cleaning cylinder 301 is fixed to the bottom of the inner wall of the outer case 101 and is located on one side of the rotating sleeve 203. The brush 302 is fixed to one side of the cleaning cylinder 301 close to the rotating sleeve 203 and is in contact with the surface of the primary filter 206. When the primary filter 206 rotates, the brush 302 is used to clean impurities on the surface of the primary filter 206.

[0051] In the present embodiment, it should be additionally explained that the cross-section of the high-efficiency composite filter 205 and the primary filter 206 is arc-shaped when viewed from above. The depth of the arc-shaped slot 204 on the upper rotating disk 201 is greater than the depth of the arc-shaped slot 204 on the lower rotating disk 201. Therefore, when the high-efficiency composite filter 205 and the primary filter 206 are pushed upward, their bottoms can be separated from the arc-shaped slot 204 below, thereby facilitating the disassembly operation of the high-efficiency composite filter 205 and the primary filter 206.
