Abstract

The invention discloses an infrared automatic hand drier circuit. The infrared automatic hand drier circuit is characterized by comprises a blower, a power circuit (1), a control circuit (2) connected with the output end of the power circuit (1), a driving circuit (3) connected with the output end of the control circuit (2), an infrared transmitting and receiving circuit (4) connected with the output end of the driving circuit (3), a signal amplifying circuit (5) connected with the output end of the infrared transmitting and receiving circuit (4), and a time-delay circuit (6) connected with the output end of the signal amplifying circuit (5). The blower is connected with the power circuit (1). According to the infrared automatic hand drier circuit, the blower is controlled through infrared to dry hands, so that compared with a traditional paper wiping mode, the infrared automatic hand drier circuit can save a large amount of paper and achieve environmental protection and energy conservation.

Description

technical field [0001] The invention relates to a circuit, in particular to an infrared automatic hand dryer circuit. Background technique [0002] It is very inconvenient for people with wet hands for a period of time after washing their hands. In order to solve this problem, at present, paper towels for wiping hands are placed in the washrooms of some public places, and these paper towels can be used to dry hands after people wash their hands, which brings convenience to people. [0003] However, the large flow of people in public places leads to a large consumption of paper towels, resulting in a great waste of resources, which is not in line with the concept of energy conservation and emission reduction advocated by the current human society. Therefore, how to solve the above problems is an urgent task for people. Contents of the invention [0004] The purpose of the present invention is to solve the defect that people use paper towels to wipe their hands and cause a...
