Automatic shifting air purifier and working method thereof

Abstract

The invention discloses an automatic shifting air purifier, which comprises a shell, air inlets, a clean air outlet, a filter screen, a fan and a control circuit, wherein the two side faces of the front part of the shell are provided with the air inlet respectively; the upper side face of the tail part of the shell is provided with the clean air outlet; the filter screen is arranged in the shell;the fan is arranged between the filter screen and the clean air outlet; the outer side of the shell is provided with a gas sensor, a fine particle sensor and a shift indicating lamp; the inner side of the shell is provided with the control circuit; the signal output ends of the gas sensor and the fine particle sensor are electrically connected with the control circuit; and the control end of the control circuit is electrically connected with the fan and the shift indicating lamp respectively. The quality of indoor air is sensed by using the gas sensor and the fine particle sensor, and the flow of purified air is adjusted by automatically adjusting the rotating speed of the fan according to the air quality with the control circuit, so that the air purifying efficiency is increased effectively.

Description

technical field [0001] The invention discloses an air purifier with automatic gear adjustment and a working method thereof, belonging to the technical field of indoor air purification. Background technique [0002] The quality of indoor environment directly affects human health. From the actual situation, while my country's economy is developing rapidly, the indoor environmental pollution caused by construction, decoration and furniture has become a big killer affecting people's health. Serious indoor environmental pollution not only causes loss to people's health, but also causes huge economic loss. Therefore, the purification of indoor air is a very practical and urgent problem. [0003] For the above-mentioned technical defects: Chinese patent CN2533415 discloses an air purification device, which mainly consists of a pre-filter layer, a high-efficiency filter layer and a sterilizing ultraviolet lamp between the two layers. There is an air inlet on the front side, and a...

[0003] For the above-mentioned technical defects: Chinese patent CN2533415 discloses an air purification device, which mainly consists of a pre-filter layer, a high-efficiency filter layer and a sterilizing ultraviolet lamp between the two layers. There is an air inlet on the front side, and a clean air outlet on the upper side of the shell, which can remove small particle pollutants such as dust and pollen in the air, and can kill bacteria in the air, but it cannot be released from furniture and building materials. Toxic gases such as formaldehyde can be effectively purified, and the flexibility of the purifier is low. The power supply is artificially controlled to realize the opening and closing of the purification, and the indoor air quality and the change of the air quality during the air purification process cannot be sensed. The actual air quality in the room is used to judge the working status of the purifier, and there is no gear shift purification, and the working status of the purifier cannot be changed immediately with the change of air quality; the purification flexibility is poor and the efficiency is not high

Chinese patent CN201195076 discloses an air purification device, which includes a box body with an air inlet and an air outlet, and a primary filter, a medium-efficiency filter, and a high-efficiency filter between the air inlet and the air outlet. There is a sterilizing and deodorizing combination device between the medium-efficiency filter and the high-efficiency filter, but its function is simple, it cannot sense the air quality in the room, and it cannot realize shifting purification

Some air purifiers can adjust gears, but they need to be manually shifted, and the working status of the purifier cannot be changed according to the real-time indoor air quality. Sometimes, when the indoor air quality is bad, the low gear is used to purify, and when the air quality is good, the high gear is used. Purification, resulting in low efficiency in purifying the air
