Abstract
The utility model which relates to an automatic control technology, in particular to a temperature controlled fan; the utility model aims at overcoming the defect that the present fans are turned on or off by the hands and provides a temperature controlled fan. The technical proposal of the utility model is that the temperature controlled fan comprising a fan is characterized in that the temperature controlled fan also comprises a temperature sensor, a signal processing circuit, a driving circuit and an AC switch. The temperature sensor is connected with the signal processing circuit; the signal processing circuit is connected with the driving circuit; the driving circuit is connected with the AC switch; the AC switch is connected with a power supply of the fan; the temperature sensor, the signal processing circuit and the driving circuit are connected with a DC power supply. The temperature controlled fan has the advantages that the fan switch is controlled by an automatic control system without manual operation, thus leading the fan to be more convenient.
Description
Technical field
The utility model relates to a kind of automatic control technology, particularly temperature controlled fan.
Background technique
All there is fan in now a lot of rooms, and most fan all needs the people for removing switch, loses time very much, and are also working waste electric power with aft-fan through the temperature decline of being everlasting.
The model utility content
The purpose of this utility model is to overcome the shortcoming that existing fan needs artificial switch, and a kind of temperature-controlled fan is provided.
The utility model solve the technical problem, the technological scheme that adopts is, temperature-controlled fan, comprise fan, it is characterized in that, also comprise temperature transducer, signal processing circuit, drive circuit, alternating-current switch and DC electrical source, described temperature temperature transducer is connected with signal processing circuit, described signal processing circuit is connected with drive circuit, described drive circuit is connected with alternating-current switch, described alternating-current switch is connected with fan power supply, and described temperature transducer, signal processing circuit and drive circuit all are connected with DC electrical source;
Concrete, described temperature transducer is a thermistor;
Concrete, described alternating-current switch is relay or controllable silicon.
The beneficial effects of the utility model are that use automatic controlling system fan swicth without manual operation, has saved the time of switch fan, makes fan more convenient.
Description of drawings
Fig. 1 is embodiment's circuit theory diagrams;
Wherein 1 is temperature transducer, and 2 is signal processing circuit, and 3 is drive circuit, and 4 is alternating-current switch, and 5 is fan power supply, and 6 is fan, and 7 is DC electrical source.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The power supply of the utility model serviceability temperature sensor control fan, the time of having saved the switch fan.
Embodiment
This example is to use the temperature-controlled fan of the technical program design, its circuit theory diagrams such as Fig. 1.
This example determines that by signal processing circuit whether temperature transducer is example 30 degrees centigrade the time.
DC electrical source 7 is to temperature transducer 1, signal processing circuit 2 and drive circuitry 3.
When temperature reached 30 degrees centigrade, the signal of temperature transducer 1 output made signal processing circuit 2 output control signals, and drive circuit 3 receives above-mentioned control signal and drives alternating-current switch 4 actions, makes fan 6 be communicated with work with fan power supply 5;
When temperature was lower than 30 degrees centigrade, the signal of temperature transducer 1 output made signal processing circuit 2 non-output signals, and alternating-current switch 4 is failure to actuate, and then fan 6 disconnects with fan power supply 5, quits work.
Because each physical circuit in the technical solutions of the utility model all belongs to related domain routine techniques, no longer describe in detail herein.Those of ordinary skill in the art according to foregoing description, can adopt various circuit to realize the technical solution of the utility model, and it all belongs to protection domain of the present utility model.
Claims (3)
1. temperature-controlled fan, comprise fan, it is characterized in that, also comprise temperature transducer, signal processing circuit, drive circuit and alternating-current switch, described temperature temperature transducer is connected with signal processing circuit, and described signal processing circuit is connected with drive circuit, and described drive circuit is connected with alternating-current switch, described alternating-current switch is connected with fan power supply, and described temperature transducer, signal processing circuit and drive circuit all are connected with DC electrical source.
2. according to the described temperature-controlled fan of claim 1, it is characterized in that described temperature transducer is a thermistor.
