Air water maker based on fingerprint recognition and face recognition

Abstract

The invention relates to the technical field of water making equipment, and discloses an air water maker based on fingerprint recognition and face recognition. The air water maker comprises a shell, acollecting water tank is fixedly installed on the bottom surface of a shell cavity, a compressor located at the right side of the collecting water tank is fixedly installed on the bottom surface of the shell cavity, and a cold storage barrel is fixedly installed on the inner wall of the shell. Air is drawn by a cross flow fan, so that the air enters a liquefaction barrel from an air inlet pipe, the arrangement of an evaporator is formed by winding a refrigeration pipe in the liquefaction barrel, so the temperature in the liquefaction barrel is reduced and gaseous water in the air is liquefied; the humidity of the air entering in the air inlet pipe is monitored in real time through a humidity sensor, so that when the air is dried, the humidity sensor closes the cross flow fan and activatesan electromagnetic valve through a control circuit board, and the tap water is automatically switched as a water source for water intake; and at this time, the air water maker has quick speed and small power consumption to obtain liquid water, and the water making cost is low.

Description

technical field [0001] The invention relates to the technical field of water making equipment, in particular to an air water making machine based on fingerprint recognition and face recognition. Background technique [0002] The water generator is a device that purifies the source water so that the quality of the source water can reach the quality of drinking water. According to the source of the source water, it can be divided into a bottled water generator, an external water generator, and an air water generator. The air water machine is also called the air water machine. Its working principle is to use the compressor to drive the evaporator to work. The evaporator condenses the gaseous water in the air into liquid water, and filters and purifies the calm liquid to make the quality of the condensed liquid water achieve drinking water quality. [0003] However, the water source of existing air water generators is limited to gaseous water in the air. When the air is relativ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an air water generator based on fingerprint recognition and face recognition, which has the advantages of low water production cost, good water quality and commercial operation, and solves the problem that the water source of the existing air water generator is limited to air. When the air is relatively dry, there is very little gaseous water in the air. At this time, the speed of obtaining liquid water by the air water generator is slow, the power consumption is large, the cost of water production is high, and the quality of the prepared drinking water is poor. It affects people's health, and at the same time, it does not have the function of paying for water, and cannot be commercialized, which limits the scope of use of the air water inlet machine.
