Air purifiers and mobile air purifiers

Abstract

The invention provides an air purifier and a movable type air purifier, and belongs to the field of purifiers. The air purifier comprises a shell body, a motor and a filter element, wherein the motor and the filter element are arranged in the shell body; an air capacity control device is arranged at the inner side of an indoor air inlet and comprises a stepping motor, an air control plate, a gear and a rack, wherein the gear and the rack are engaged with each other, the stepping motor drives the gear to rotate, the rack is arranged on the air control plate, and the indoor air inlet is gradually opened or gradually closed in the reciprocating movement process of the air control plate driven by the gear; and the air capacity control device is provided with a dust-proofing system, the dust-proofing system comprises a dust-proofing shell, and the dust-proofing shell is arranged at the outer side of the gear in a covering mode. The air capacity control device with the dust-proofing system is suitable for being mounted in the air purifier to conduct air capacity controlling, and the dust-proofing system has the effect of blocking dust, so that the normal use of the air capacity control device is ensured and the service life of the air capacity control device is prolonged. The movable air purifier comprises the air purifier, rollers are arranged at the bottom of the shell body, and therefore the movable type air purifier is convenient to move.

Description

technical field [0001] The invention relates to the field of purifiers, in particular to an air purifier and a mobile air purifier. Background technique [0002] Most of the existing air purifiers are limited in size, and the installation space in the housing is also limited, and the overall air intake and purification volume are very limited; they are installed in different environments, different environments and supply and demand objects. The demand for purification capacity of the device is different. Therefore, it is very necessary to adjust and control the air purification rate of the air cleaner, and it is even more necessary to design a structure suitable for controlling the air intake rate in the air cleaner. Contents of the invention [0003] The object of the present invention is to provide an air cleaner, so as to provide an air volume control device with a dust-proof system. [0004] Another object of the present invention is to provide a mobile air cleaner ...
