Abstract

The utility model is a miniature air purifier device, which is characterized in that it is composed of a fan, a negative ion ozone generating circuit, an air odor sensor, a motor control circuit, a single-chip microcomputer control circuit and an active carbon particle filter. The air circulates through the rotation of the fan. After the air with pollutants is sucked into the purifier, it is automatically sterilized and deodorized by negative ion ozone, and then the clean air is blown out through the filtration of activated carbon particles, so as to quickly decompose various pollutants in the air. Smoke, musty, and peculiar smells make the indoor air quality meet the "healthy air" standard.

Description

A miniature air purifier

technical field

The utility model relates to a miniature air purifier, which is a kind of air purifier capable of filtering smoke, removing peculiar smell, eliminating bacteria and viruses, supplementing negative oxygen ions and active oxygen (03) to meet people's requirements for indoor air quality, and reaching air purification efficiency. Refreshing purpose.

Background technique

With the increasingly serious pollution of living environment, interior decoration and decoration materials, polluted air sources have become one of the invisible killers affecting human health. The survey found that about 70% of people's life time is spent indoors, and the average daily inhalation of air is 12 cubic meters, while urban residents spend about 70%-90% of their time in various indoor environments every day. 68% of human diseases are related to air pollution. The World Health Organization lists indoor air pollution as the first of 18 types of carcinogens, and indoor air pollution is five times higher than outdoor air pollution. With the improvement of people's living standards, people are increasingly aware of the importance of clean air to their health. Therefore, air purifiers are gradually entering homes and various office spaces.

Contents of the invention

The purpose of the utility model is to provide a kind of miniature air purifier with simple design structure, convenient operation and wide practical range.

The purpose of this utility model is achieved in that a miniature air purifier is designed, which is characterized in that: the purifier is cylindrical and is composed of a first housing, a second housing and a third housing, the first housing The two ends are respectively connected with a second shell and a third shell.

An air odor sensor, an indicator light, and a button are installed on the first housing.

An activated carbon particle filter is installed inside the second housing, and an air outlet filter is installed at the air outlet.

A control box and a fan are installed inside the third housing, and an air inlet filter is installed at the air inlet.

The control box includes a single-chip microcomputer, an anion ozone generating circuit, an air odor sensor circuit, a motor control circuit, and a single-chip microcomputer control circuit.

The utility model has the advantages that: it is controlled by a single-chip microcomputer, and the environmental information is automatically collected by the air odor sensor and sent to the single-chip microcomputer. The air enters the activated carbon particle filter and is purified again to absorb trace toxic gases such as formaldehyde and benzene in the air to achieve the purpose of purifying the air. The utility model can automatically adjust the working state of the air purifier, and realizes the characteristics of intellectualization, energy saving and environmental protection of the product.

specific embodiment

Example

As shown in FIG. 1 , FIG. 2 and FIG. 3 , a miniature air cleaner includes a first housing 1 , a second housing 2 and a third housing 3 . Its characteristics are: the purifier is cylindrical and is composed of a first shell 1, a second shell 2, and a third shell 3, and the two ends of the first shell 1 are respectively connected with the second shell 2 and the third shell Body 3. An air odor sensor 4 , an indicator light 5 and a button 6 are installed on the first housing 1 . An activated carbon particle filter 12 is installed inside the second housing 2 , and an air outlet filter screen 13 is installed at the air outlet 7 . A control box 11 and a fan 10 are installed inside the third housing 3 , and an air inlet filter 9 is installed at the air inlet 8 . As shown in Figure 4, the control box 11 includes a single-chip microcomputer, negative ion ozone generation circuit, air odor sensor circuit, motor control circuit, single-chip microcomputer control circuit.

During use, start purifier button 6, pilot lamp 5 lights, and air peculiar smell sensor 4 begins to gather environmental information automatically and sends to the single-chip microcomputer in the control box 11, and the single-chip microcomputer is to the processing of data in time and accurately, sends out control negative ion ozone generating circuit and motor then command to control the circuit. The fan 10 starts to run, and the polluted air is drawn into the third housing 3 through the air inlet filter 9 of the air inlet 8, and the air treated with negative ions and ozone enters the first housing 1 and the second housing 2 in sequence . Through the activated carbon particle filter 12 inside the second casing 2, purification treatment is performed again to absorb trace amounts of toxic gases such as formaldehyde and benzene in the air. The purified air is blown out from the air outlet filter screen 13 of the air outlet 7 through the action of the fan 10 to achieve the purpose of purifying the air.
