Abstract
The utility model relates to an automatic temperature-regulating fan, which comprises a fan motor. The automatic temperature-regulating fan is characterized in that the fan motor, a thermistor with a negative temperature coefficient, a switch and a power supply are connected in series to form an automatic temperature-regulating circuit. By adopting the heat sensitivity of the thermistor with the negative temperature coefficient, the size of the current getting through the fan can be changed through detecting the ambient temperature so as to adjust the rotating speed of the fan by the an automatic temperature-regulating fan, thereby the purposes of saving energy and lowering the temperature are realized.
Description
Technical field
The utility model relates to a kind of fan, specifically is a kind of automatic temperature-control fan.
Background technique
Existing ceiling fan when in use can only be in hot summer; When you fall asleep at dead of night, possibly will become cold by weather; Possibly will catch cold if do not turn off ceiling fan or open point, bring injury for our physical and mental health, nor be beneficial to energy-conservation.
The model utility content
In order to overcome the shortcoming that above-mentioned existing technology exists, the purpose of the utility model is to provide a kind of automatic temperature-control fan, and it changes the rotating speed of regulating fan through the size of current of fan through the temperature of testing environment, thereby reaches the purpose of energy-conservation temperature adjustment.
In order to address the above problem, the utility model adopts following technological scheme: this automatic temperature-control fan, comprise fan electromotor, and said fan electromotor is connected with a negative tempperature coefficient thermistor, switch, power supply and is constituted an automatic temperature-control loop.
The beneficial effect of the utility model is: this automatic temperature-control fan is the thermal sensitivity that utilizes negative tempperature coefficient thermistor, and the temperature through testing environment changes the rotating speed of regulating fan through the size of current of fan, thereby reaches the purpose of energy-conservation cooling.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the utility model embodiment's circuit theory diagrams.
Embodiment
As shown in Figure 1, this automatic temperature-control fan comprises fan electromotor M, and said fan electromotor M connects with a negative tempperature coefficient thermistor R1, K switch, 220V power supply and constitutes an automatic temperature-control loop.
When temperature raises; Negative tempperature coefficient thermistor R1 diminishes with temperature rising resistance value; Thereby the resistance electrorheological that diminishes in the automatic temperature-control loop is big in the automatic temperature-control loop, and promptly the electric current through fan electromotor M will increase, thereby reaches the purpose that improves rotation speed of the fan.
When temperature reduces; Negative tempperature coefficient thermistor R1 reduces resistance value with temperature and becomes big; Resistance becomes that thereby electric current diminishes in the big automatic temperature-control loop in the automatic temperature-control loop, and promptly the electric current through fan electromotor M will diminish, thereby reaches the purpose that reduces rotation speed of the fan.
Resistance R 1 is the custom circuit original paper, repeats no more.
