Variable-power air purifier

Abstract

The invention discloses a variable-power air purifier. The air purifier comprises a working box and filter cotton in the working box, an air inlet located at the lower side of the filter cotton is arranged in the work box in a penetrating mode, the air inlet penetrates leftwards and is communicated with the outside, a motor is fixedly arranged on the upper cavity wall of the air inlet, the lower end surface of the motor is in power connection with a motor shaft, fan blades are fixedly arranged on the motor shaft, and a concentration detector positioned at the lower side of the motor shaft is fixedly arranged in the air inlet. The output efficiency of the motor can be changed according to the concentration of harmful substances in air, and when the concentration in the air is high, a filterplate can be popped up, air is simply filtered and adsorbed, and the rotating speed of the motor is increased, so that the speed of air entering the air purifier is increased, the residence time of air in the air purifier is prolonged, harmful substances in air can be fully adsorbed by the air purifier, and finally, and purified air is humidified and then exhausted by the air purifier.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to a variable power air purifier. Background technique [0002] Air purifiers refer to products that can absorb, decompose or transform various air pollutants, generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc., to effectively improve air cleanliness. The existing air purifiers on the market are all output with one power. When the concentration of harmful substances in the air is high, the effect of purifying the air with the same power is poor. Therefore, a variable power is urgently needed. An air cleaner is used to solve the above-mentioned problems, and the present invention improves on the above-mentioned shortcomings. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a variable power air cleaner, which overcomes the above-mentioned problems. [...
