Electric heating fan based on single-chip control

Abstract

The invention discloses an electric heating fan based on single-chip control. The electric heating fan based on single-chip control comprises a base, a control panel, a liquid crystal display screen, a support rod, a fan head, a temperature sensor, a pyroelectric infrared sensor, a single-chip, a safety resistor, a positive temperature coefficient thermistor and a lead; the lower end of the support rod is fixed on the base; the control panel and the fan head are fixed on the support rod; the liquid crystal display screen, the temperature sensor, the single-chip and the pyroelectric infrared sensor are arranged on the control panel; and a heating part of the fan head is connected with the single-chip through the lead by the positive temperature coefficient thermistor and the safety resistor. When no person is in a room, the electric heating fan can be automatically closed; and when an indoor temperature is higher, heat generated by the positive temperature coefficient thermistor is gradually reduced, the power of the electric heating fan can be automatically reduced, the working time of the electric heating time is shortened, or even the electric heating fan is closed, the humanization is achieved, and more energies are saved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an electric heating fan controlled by a single-chip microcomputer. Background technique [0002] People in most parts of my country will use electric heating fans to resist the cold in winter. When we are indoors, when we turn on the electric fan, the indoor temperature will gradually rise. However, the electric fans sold on the market are all constant power. Once the electric fan is turned on, it will Continuous heating will not only cause the temperature to be too high, but also waste resources, which is very inconsistent with the purpose of energy conservation and emission reduction advocated by today's society. Contents of the invention [0003] Aiming at the problem that the traditional electric heating fan cannot automatically adjust the heat according to the change of the environment, the invention provides an electric heating fan based on the control of a single-chip microcomput...
