Air purification device convenient to maintain

Abstract

The invention discloses an air purification device convenient to maintain. The air purification device comprises an outer shell, an inner shell and a guide device; the outer shell is provided with an opening, and a mounting cavity is formed inside the outer shell; the inner shell is arranged in the outer shell from the opening, and air purification chemicals are arranged in the inner shell; the guide device is connected between the outer shell and the inner shell, and the inner shell can move between a storage state and a moving-out state along the guide device; in the storage state, the inner shell is arranged in the mounting cavity, and in the moving-out state, the inner shell moves out of the mounting cavity and is connected with the outer shell through the guide device; and the guide device comprises a guide unit and a rotary connecting piece, the rotary connecting piece is connected between the inner shell and the guide unit, and in the moving-out state, the inner shell rotates by a certain angle along the rotary connecting piece and inclines relative to the outer shell. In the maintenance process of the air purification device, the inner shell does not need to be taken down, so that the disassembly and assembly step is avoided; and the operation can be completed by one person with two hands, and external tools are not needed in the whole process, so that operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification device which is easy to maintain. Background technique [0002] Air purification devices, 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.), products that effectively improve air cleanliness are mainly divided into household, commercial, industrial, and building. The existing air cleaning device is a fixed structure as a whole. For example, such an air purification device is disclosed in the patent application number 201821999260.4, including: a sheet metal casing, the sheet metal casing includes a sheet metal upper casing and a sheet metal lower casing, and the sheet metal upper casing The body is detachably connected with the sheet metal lower casing...

AI Technical Summary

Problems solved by technology

And the air cleaning device needs to frequently replace the filter screen or place new air cleaning medicine when in use, if the air cleaning device is installed on the ceiling and other positions, generally the outlet of the filtered air is set at the bottom of the shell, and the medicine's The installation port and the filter screen installation port should also be set at the lower part of the shell. When changing the medicine, it is very inconvenient for people to perform maintenance operations with their heads up. First, it is not convenient to observe the inside of the air purification device from a correct perspective. Second, since the air purification device will inevitably have dust attached after long-term use, it is inevitable that dust will fall into the eyes when the operator maintains the air purification device, affecting vision.

Therefore, the design of existing air cleaning devices is not ideal enough.
