Abstract
The invention discloses a solar electric fan capable of automatically regulating speed by means of temperature and infrared ray. The solar electric fan comprises a fan motor, a temperature sensor, an infrared induction sensor and a singlechip, wherein the fan motor is connected with a solar battery through a rotation speed control circuit; the output signals of the temperature sensor and the infrared induction sensor are connected with the singlechip; and the output of the singlechip is connected with the rotation speed control circuit. Environmental temperature, infrared strength and other index signals are transmitted to the singlechip, and the singlechip automatically outputs the signals according to a set value to control the rotation speed of the fan motor, thereby being convenient for use. The solar electric fan is especially suitable for installing in equipment, so that when the temperature in the equipment is low, the rotation speed of the fan is reduced so that energy can be saved; and when the equipment runs at the high temperature, the rotation speed of the fan is improved, thereby avoiding that the equipment is damaged due to over high temperature and prolonging the service life of the equipment.
Description
Technical field:
The present invention relates to a kind of electric fan, especially a kind of solar-electricity fan of realizing temperature and infrared rays automatic speed regulation.
Background technique:
Electric fan drives by fan electromotor, and the rotating speed of traditional electrical fan is can't regulating of fixing, and people can not select the rotating speed of fan as required, make the people feel inconvenience.In order to address this problem, existing electric fan is provided with adjustable potentiometer and driving switch between input power supply and fan electromotor, and people can regulate rotation speed of fan by the conversion driving switch.But manual tune is cumbersome on the one hand, can't be applicable to the cooling fan in the equipment of being installed in (computer, DVD, TV etc.) on the other hand, and there are the following problems for this reason:
1. when equipment is worked, though do not need high rotating speed fan, even do not need fan under the lower environment of temperature, fan still rotates with constant speed, causes waste of electric energy;
2. when equipment is play under the higher environment of temperature, need the fan high speed rotating, but fan cause equipment to damage because of the casing inside temperature is too high still with the constant speed rotation, has reduced the working life of equipment with rapid cooling.
Summary of the invention:
The present invention provides a kind of solar-electricity fan of realizing temperature and infrared rays automatic speed regulation in order to solve the above-mentioned technical problem of existing in prior technology.
Technical solution of the present invention is: a kind of solar-electricity fan of realizing temperature and infrared rays speed governing, fan electromotor is arranged, and described fan electromotor joins by rotating-speed control circuit and solar cell; Be provided with temperature transducer, infrared induction sensor and single-chip microcomputer, temperature transducer and infrared induction signal of sensor and single-chip microcomputer join, and the output and the rotating-speed control circuit of single-chip microcomputer join.
Described rotating-speed control circuit is the SCR control circuit.
Temperature transducer and infrared induction sensor that the present invention is provided with can be delivered to single-chip microcomputer with index signals such as ambient temperature and infra-red intensities, and single-chip microcomputer is then according to the automatic output signal control of setting value fan motor rotational speed, and is very convenient to use.Be particularly useful for being installed in the fan of device interior, can be when the device interior temperature be low, the rotating speed that reduces fan is with energy saving; When equipment moves under the higher temperature environment, can improve the rotating speed of fan, prevent that equipment Yin Wendu is too high and damage, can increase the working life of equipment.
