Intelligent monitoring system used for air purifier based on signal adjusting circuit

Abstract

The invention discloses an intelligent monitoring system used for an air purifier based on a signal adjusting circuit. The intelligent monitoring system is characterized by being mainly composed of a microprocessor, the signal adjusting circuit, a display, a power source, a conversion recognition circuit and an air speed sensor, wherein the signal adjusting circuit, the display and the power source are connected with the microprocessor, the conversion recognition circuit is connected with the signal adjusting circuit, and the air speed sensor is connected with the conversion recognition circuit; the conversion recognition circuit is composed of a conversion chip U1, a signal input circuit and a signal amplification shaping circuit, wherein the input end of the signal input circuit is connected with the air speed sensor, the output end of the signal input circuit is connected with the conversion chip U1, the input end of the signal amplification shaping circuit is connected with the conversion chip U1, and the output end of the signal amplification shaping circuit is connected with the signal adjusting circuit. The intelligent monitoring system is simple in structure and low in cost, the condition that dust particles are attached to a filtering net can be known without demounting the air purifier, whether the filtering net needs to be cleaned or not is judged, and therefore the intelligent monitoring system is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an intelligent monitoring system for an air purifier based on a signal regulating circuit. Background technique [0002] The air purifier mainly cleans the air by absorbing particulate impurities in the air. After the air purifier has been used for a period of time, the filter will absorb a large amount of particulate impurities, which will affect the dust removal effect. Therefore, it is necessary to remove the particulate impurities adsorbed on the filter. At present, users cannot determine the adsorption of the filter when using the air purifier, and can only disassemble the air purifier from time to time in order to check the adsorption of the filter and clean the filter, which brings great inconvenience to the user. Big inconvenience. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the current user cannot determine the adsorptio...
