Detailed Description
The structure of the present invention will be further described with reference to the accompanying drawings and preferred embodiments of the present invention.
Referring to fig. 1 to 3, the energy-saving control fan of the present invention includes a bracket 1, a motor 2 and fan blades 3, wherein the motor 2 is mounted on the bracket 1, and the motor 2 is connected with the driving fan blades 3; the motor is characterized by also comprising a first temperature control switch module and a second temperature control switch module which are connected with the motor in series; the first temperature control switch module, the second temperature control switch module and the motor are connected in series, the first temperature control switch module is switched on after the temperature reaches a low-temperature preset value according to the detected temperature, and the second temperature control switch module is switched off after the temperature reaches a high-temperature preset value according to the detected temperature.
The first temperature control switch module is mainly used for detecting the temperature of the external environment, or detecting the temperature of a radiator and a radiating fin needing to radiate, for example, when the detected temperature is lower than 40 ℃, the first temperature control switch module keeps an off state, and the motor 2 is in a low-speed running state; the low speed is relative to the rotating speed of the normal operation of the motor 2, so that the fan blade 3 can rotate after being electrified, the circuit of the motor 2 can be visually confirmed to be normal by naked eyes, and the low speed does not play a role in substantial heat dissipation at the moment, so that the technical effects of saving energy and solving the noise of a fan are achieved.
The first specific scheme for realizing the functions is as follows: the first temperature control switch module is a first thermistor which is conducted after the temperature is increased to more than 40 ℃. Scheme II: the first temperature control switch module comprises a first temperature sensor for detecting external temperature and a low-temperature control switch for controlling the direct conduction of the motor and the power input circuit according to a sensing signal of the first temperature sensor; the low-temperature control switch is connected with a motor low-speed operation control circuit in parallel. The motor low-speed operation control circuit may be specifically a resistor connected in series between the power input circuit and the motor 2. When the low temperature control switch is turned on, the resistor is shorted. The first temperature sensor is preferably arranged on the inner side surface 11 of the bracket 1, and the first temperature sensor can be directly attached and connected with a required heat dissipation component while the bracket 11 is fixedly installed on the required heat dissipation component, or the first temperature sensor can be installed on the side surface 12 of the motor installation seat of the bracket 1. The low-temperature control switch is conducted after the temperature signal provided by the first temperature sensor is higher than a starting preset value.
The second temperature control switch module is mainly used for safety protection, is conducted in a normal state, and only after the temperature of the motor exceeds the normal heating temperature, the power supply of the motor is disconnected, so that the phenomenon that the motor is heated due to the fact that the fan is easily abraded and clamped or blocked by foreign matters, a cabinet is ignited, and a server is ignited is avoided.
The implementation scheme can be as follows: the second temperature control switch module is a temperature control switch which is disconnected after the temperature rises to over 130 ℃. It can also be: the second temperature control switch module comprises a second temperature sensor arranged in the motor 2 and a high-temperature control switch for controlling the motor circuit to be switched off according to a sensing signal of the second temperature sensor. The high-temperature control switch is connected with the motor in series, the high-temperature control switch is disconnected after a temperature signal provided by the second temperature sensor is higher than a stop preset value, the stop preset value can be 130 degrees for example, and after the temperature signal is higher than 130 degrees, the motor is in a power-off protection state, and all circuits are powered off and do not work.
In order to realize detection and prompt of abnormal heating before the power-off protection state is not reached, the invention also comprises a temperature control alarm module; the temperature control alarm module comprises a buzzer and an alarm control switch which is connected with the second temperature sensor and is used for controlling the buzzer to alarm in sound. For example, when the second temperature sensor detects that the temperature in the motor rises to 110 ℃, the alarm control switch is turned on, and the buzzer starts to alarm to remind people to intervene for investigation. In the specific implementation process, the alarm control switch can also be an independent temperature control switch and is not required to be connected with the second temperature sensor.
Because the existing fan indicator lamp or decorative lamp is bound by the power cord, generally fixed installation, dynamic effect picture, not favorable to the dynamic display of the mark, the invention is equipped with LED lamp on the said flabellum 3, LED lamp connects with the wireless induction receiving coil 41, the wireless induction receiving coil 41 can be installed on the medial surface of the centre of flabellum 3 specifically; the wireless induction transmitting coil 42 is arranged on the bracket 1 or the stator of the motor, the wireless induction transmitting coil 42 and the wireless induction receiving coil 41 are correspondingly arranged, and the wireless induction transmitting coil is connected with the motor 2 in parallel. Thereby realize the wireless power supply connection of LED lamp, the LED lamp can be rotatory along with flabellum 3, will can single pointolite convert annular area light source into, simultaneously, the transport state of visual effect feedback motor that can also pass through the LED lamp directly perceived, and the motor stops, and what show is the pointolite, and the running state is annular area light source. Before the first temperature control switch module is not conducted, although the rotating speed of the fan is low, as long as the LED lamp is lightened, the fan works normally, the problem that the quality of the fan is considered to be poor due to the fact that the rotating speed of the fan is low is avoided, when the ambient temperature is higher than 40 degrees, the first temperature control switch module is completely conducted, the resistance value is 0, and the fan runs at full speed.
Because the motor 2 generally works on 220V alternating current, and the buzzer and the wireless induction transmitting coil 42 generally need a safe low-voltage power supply for working, the stator of the motor is also provided with a secondary winding, and the coupling voltage output end of the secondary winding supplies power for the wireless induction transmitting coil and the temperature control alarm module.
