Abstract

The invention relates to an internal and external circulation positive pressure air purifier. The purifier comprises a controller and a main body with a chamber, wherein the chamber is divided into an air inlet chamber and an air flue chamber by a filter installed in the chamber; the portion, where the air inlet chamber is formed, of the main body is provided with an external circulation air inlet and an internal circulation air inlet; the external circulation air inlet is communicated with the outside through a through-wall fresh air pipe, and the internal circulation air inlet is communicated with a room; a draught fan with a control end in communicating connection with a controller is installed in the air flue chamber; the portion, where the air flue chamber is formed, of the main body is provided with an air outlet which is communicated with the room; an internal circulation air valve is installed in the internal circulation air inlet and is a hand valve or an electric valve with a control end in communicating connection with the controller. The purifier has the advantages that a pressure difference exists between the outside and the room, and healthy indoor air is ensured; wind resistance is small, air flow is smooth, and accordingly the requirement for power of the draught fan is low, and energy is saved; installation is convenient without limitation; a negative ion assembly further purifies the air.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to a positive pressure purifier for internal and external circulation air. Background technique [0002] At present, most of the air purifiers on the market are internal circulation, and the ones with external circulation are very expensive, and the installation is also very troublesome. The common problems of internal circulation air purifiers are that oxygen and negative ions will be less and less, and carbon dioxide will be less and less. Therefore, the air produced by it is not healthy air, and the air pressure inside and outside the house is the same, and the external polluted air is easy to enter. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a positive pressure purifier for internal and external circulation air, under the action of the fan, the outdoor air and indoor air flow thr...
