The conductor contact piece 407 does not contact the first conductor piece 404 without being subjected to an external force, so that the off-center warning lamp 401 does not emit light when the micro-machine state is normal.
The middle part of the second fixing plate 103 is provided with a vent channel 506, one end of the vent channel 506 is communicated with the top end of the high-temperature oil duct 503, one end of the vent channel 506, which is far away from the high-temperature oil duct 503, is communicated with the outside, the vent channel 506 can enable the top end of the block 504 to obtain atmospheric pressure, when the temperature of the micro-motor is recovered to be normal, the block 504 can descend along with the oil level, and the diameter of the bottom end of the high-temperature oil duct 503 is smaller than that of the top end, so that the block 504 cannot leak into the kerosene bin 201.
The working principle is as follows:
the micro motor is embedded and installed in the center of the first fixing plate 102 and the second fixing plate 103, so that the micro motor is fixed, the micro motor can generate heat when in operation and simultaneously generate vibration, kerosene is stored in the kerosene bin 201, heat generated by the motor in operation is transferred to the kerosene in the kerosene bin 201 through the supporting shell 101, the kerosene is expanded by heating and contracts by cooling, the volume change range of the kerosene is large, when the temperature of the micro motor is higher, the kerosene can absorb enough heat to expand, the kerosene in the kerosene bin 201 can expand to enter the heat dissipation elastic tube 203, the heat dissipation elastic tube 203 made of plastic material can be selected, the plastic material is easier to deform compared with metal material, the vibration generated by the motor is transferred to the heat dissipation elastic tube 203 to be amplified, the heat dissipation elastic tube 203 can swing transversely and greatly, the heat exchange efficiency between the kerosene in the heat dissipation elastic tube 203 and outside air can be effectively accelerated, and the quick cooling effect of the micro motor can be realized, kerosene can be rapidly cooled and can be contracted into the kerosene bin 201 again, the top end of the heat dissipation elastic tube 203 is fixedly provided with an oil-proof breathable film, so that the phenomenon that the kerosene is greatly lost due to the inclination of the device can be avoided, the heat dissipation elastic tube 203 is separated from the outside by the heat dissipation baffle 204, and the heat dissipation elastic tube 203 can be prevented from being damaged due to collision;
slight vibration generated during the operation of the micro-motor is matched with the elastic force action of the first spring 304 to drive the air isolation plate 305 to transversely and repeatedly swing, the isolation rubber sleeve 306 plays a role in sealing the space around the first spring 304, so that the space around the first spring 304 can only exchange gas with the external air through the ventilation slotted hole 303, the air isolation plate 305 swings to cause the space around the first spring 304 to be reduced or enlarged, a plurality of heat dissipation auxiliary components act together to ensure that the gas inside the auxiliary heat dissipation groove 301 generates intermittent compression and stretching, the air inside the auxiliary heat dissipation groove 301 absorbs the kerosene heat from the bottom end of the kerosene bin 201 to form hot air, when the hot air inside the auxiliary heat dissipation groove 301 is compressed, the hot air can be discharged into the external atmosphere through the auxiliary heat dissipation slotted hole 302, and when the air inside the auxiliary heat dissipation groove 301 is stretched, the air pressure inside the auxiliary heat dissipation groove 301 is lower than the external standard atmospheric pressure, external normal-temperature air can flow into the auxiliary heat dissipation groove 301 through the auxiliary heat dissipation groove hole 302, and high-efficiency absorption of kerosene heat in the kerosene bin 201 is realized through high-frequency ventilation in the auxiliary heat dissipation groove 301, so that the heat dissipation effect of the device on the micro motor is further effectively improved;
when the micro-motor is eccentric during operation due to failure, the micro-motor vibrates greatly to drive the whole device to vibrate, the vibration amplitude of the device is increased, the vibration amplitude of the heat dissipation elastic tube 203 in the first fixing plate 102 is increased, the heat dissipation elastic tube 203 strikes the stress block 408 discontinuously, the stress block 408 is made of an insulating material, the stress block 408 sequentially pushes the second conductor piece 406 and the conductor contact piece 407 under the action of the supporting elastic force of the second spring 405, the conductor contact piece 407 is in discontinuous contact with the first conductor piece 404, the eccentric alarm lamp 401, the first battery 402, the first conductor piece 404, the conductor contact piece 407 and the second conductor piece 406 form a series circuit when in contact, the eccentric alarm lamp 401 emits light, insulating gaskets are fixedly arranged at two ends of the second spring 405 to prevent the second spring 405 from influencing the normal circuit connection relationship, because the conductor contact piece 407 is in intermittent contact with the first conductor piece 404, the off-center warning light 401 will produce intermittent illumination to indicate to the operator that the micro-machine is malfunctioning and needs to be repaired or replaced;
the top height of the high-temperature oil duct 503 is higher than that of the heat dissipation elastic tube 203, so that only when the oil level inside the heat dissipation elastic tube 203 completely reaches the top end, the blocking block 504 can be jacked by kerosene inside the high-temperature oil duct 503, the third conductor block 505 moves upwards under the force of the second battery 502 to be in electrode contact with the second conductor block 505, at the moment, the second alarm lamp 501, the second battery 502 and the third conductor block 505 form a series circuit, the second alarm lamp 501 is normally on, the operating temperature of the micro-motor is prompted to be too high, and the micro-motor maintenance and long-term use are facilitated.
