Indoor air purifier

Abstract

The invention discloses an indoor air purifier. The indoor air purifier comprises a main case, a filter unit, a draught fan and an air exhaust device, wherein the filter unit and the draught fan are arranged in the main case, and the air exhaust device is arranged above the top of the main case. The top and the bottom of the main case are provided with openings. The two sides of the bottom of the main case are respectively provided with a support, so that the main case is suspended, and the opening in the bottom of the main case serves as an air inlet. The draught fan comprises a driving motor with two output shafts, wherein the driving motor is fixed into the main case, and the two output shafts of the driving motor are respectively connected with a wind wheel; a volute is arranged on the periphery of each wind wheel, and the upper end of each volute is communicated with the air exhaust device. Air can enter the bottom of the indoor air purifier at 360 degrees so that the requirement for large-area air purification can be met; air flow absorbed from the bottom can be exhausted from four sides of the top through the wind wheels on the two sides at the same time, and strong negative pressure is formed in an air flue, so more air can be absorbed in from the air inlet in the bottom, the adsorption capacity of the air inlet can be increased, more air can be filtered in a short time, the circulation speed of the air in a room can be increased to the maximum extent, and the efficient purifying effect can be achieved.

Description

technical field [0001] The invention relates to a gas treatment device, in particular to an indoor air purifier. Background technique [0002] According to statistics, about 70% of the time in a person's life is spent indoors, so the safety of indoor air is closely related to the health of the human body. At present, indoor air pollution mainly comes from four major sources: solid (particulate matter) pollutants, including dust particles, pollen, smoke, etc.; chemical pollutants, such as interior decoration materials, furniture and some cleaning products containing chemical substances of different components; Biological pollutants, such as dust mites, bacteria, mold and other microorganisms; and odors. The above-mentioned pollution can cause allergic reactions, chronic respiratory diseases, etc., and cause harm to human health. [0003] For this reason, some indoor air purifiers have been disclosed, which can absorb, decompose or transform various air pollutants, and effec...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned air purifiers all use the way of air intake from the side and air outlet from the top. However, in this way, the air can only enter the interior of the purifier from one side or two sides, and the air intake volume is small. In addition, the fan only has one fan. It may cause the fan to run unstable, and it has a limited effect on increasing the air volume of the air inlet, which makes the air circulation speed slow, resulting in low purification efficiency and poor purification effect
