Cylindrical air purifier

Abstract

The invention provides a cylindrical air purifier, comprising a water filtering unit, a transferring unit and an air supply unit. The water filtering unit comprises a cylindrical box; the top of the cylindrical box is open; the transferring unit comprises an air collecting cylinder; the bottom of the air collecting cylinder is matched with and in threaded connection with the top of the cylindricalbox; the air supply unit comprises a sterilization cover; the upper and lower ends of the sterilization cover are both provided with circular openings; the lower end of the sterilization cover is provided with a convex ring part matched with the top of the air collecting cylinder; an annular ultraviolet lamp tube is installed on the sterilization cover along the periphery of the inner wall of thesterilization cover; a bearing frame is arranged at the upper end of the annular ultraviolet lamp tube; and an air outlet cap is rotatably arranged on the bearing frame. The cylindrical air purifieris convenient to maintain and detach, reduces the after-sales maintenance difficulty, reduces the later replacement cost waste caused by the utilization of a multi-layer filtering structure, and can achieve the uniform air supply effect while the air quality is fully improved.

Description

technical field [0001] The invention mainly relates to the technical field of air purification equipment, in particular to a cylindrical air cleaner. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), home appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building. [0003] For example, the patent publication number is a cylindrical air cleaner provided by CN205299769U, which belongs to a cylindrical air cleaner and includes a casing. The bottom of the casing is provided with an air inlet, and the top of the casing is provided with an air outlet. A lower filter body and an upper filter body are provided sequentially from bottom to top; a plurality of support bars are ...

AI Technical Summary

Problems solved by technology

[0005] 1. The internal structure is complicated, the disassembly is not convenient enough, and the after-sales maintenance is difficult;

[0006] 2. More spare parts for the filter layer are used, which need to be replaced frequently in the later stage, and the cost of use is high;

[0007] 3. The direction of the air outlet is relatively fixed, and the air outlet is facing upwards, which is easy to accumulate dust
