Problems solved by technology

In these existing bio-type air filtration and purification technologies, long-term work makes the air continuously flow through the cultivation medium, which will cause the loss of water in the cultivation medium. If the water is not replenished in time, the cultivation medium will be too dry and cause plant damage. and microbial growth is impaired or even dies

Embodiment Construction

[0012] The present invention will be described below according to the accompanying drawings.

[0013] figure 1 Among them, P1 is a commonly used capacitive soil humidity sensor module, which is installed in the cultivation medium of the biological air filter and purification device, and its output voltage value changes linearly with the humidity of the cultivation medium. After adjustment, it is connected to the detection input terminal of the detection control circuit composed of operational amplifier circuit IC1 (LM358), that is, the positive phase input terminal. When the water content of the cultivation medium is sufficient, that is, the humidity is normal, the output voltage value of the humidity sensor P1 is relatively large. The output terminal of IC1 is high level, the relay J1 is not closed, and the 12V power supply is connected to the fan M through the normally closed contact of J1, so that the fan M works, that is, the biological air filter works normally.

Abstract

The invention relates to a biological air purifier with a function of non-contact media humidity detection. The biological air purifier comprises a fan and is characterized by also comprising a humidity sensor for detecting the humidity of culture media, wherein the humidity sensor is connected to an input end of a detection control circuit which is used for detecting humidity value of the humidity sensor and controlling the work of the fan. The biological air purifier utilizes the humidity sensor to detect the humidity of the culture media. When the humidity value of the culture media is smaller than a determined value, i.e. water content in the culture media is too low, the fan is immediately stopped so that a plant body can not be endangered due to the excessive dryness of the culture media.

Description

technical field [0001] The invention relates to an air purifier which uses organisms to filter and purify air. Background technique [0002] Bio-type air purification devices and other technologies that use cultivated plants to filter and purify the air, such as Chinese patent applications 99117903. It flows through the medium, and the microorganisms around the cultivation medium, plants and plant roots decompose and absorb pollutants in the air, so as to achieve the purpose of filtering and purifying the air. The No. 200710026399.0 Chinese patent application also discloses a detachable ecological air purifier, wherein the biological system part including the flower pot, the cultivation medium and the plant body, and the electrical host part including the blower fan can be easily Separation makes the use more reasonable and convenient. In these existing bio-type air filtration and purification technologies, long-term work makes the air continuously flow through the cultiva...
