The double-head motor rotating shaft vibration feedback mechanism comprises a light channel penetrating through the reversing plug, a laser tube and a projection plate positioned outside the powder injection nozzle body, light emitted by the laser tube irradiates the projection plate through the light channel, the laser tube is connected with a shell of the reversing plug rotating motor, the projection area of the light emitted by the laser tube is smaller than 0.1 square millimeter, and the opening area of the light channel is smaller than or equal to the projection area of the light emitted by the laser tube. When the motor bearing damages, the vibration range (radial swing range can increase) when the motor shaft rotates can increase, whether the motor bearing damages can be known in the range by judging the vibration range, so that the maintenance can be carried out in time. When the swing amplitude of the motor shaft exceeds the set range, light cannot continuously penetrate through the light channel to irradiate the projection plate (namely no light or flicker is generated on the projection plate), and a user judges whether the vibration meets the requirement or not by judging whether the light is not generated on the projection plate or the flicker is generated on the light. If within range, the light is always incident on the projection panel.
The laser tube heating device comprises a laser tube, a heating structure and a radiator, wherein the laser tube is a green laser diode, the heating structure comprises a heat conduction substrate and a surface mounted resistor arranged on the heat conduction substrate, the radiator is provided with a laser tube mounting hole and a heating structure mounting hole which are communicated together, the heat conduction substrate is mounted in the heating structure mounting hole and is connected with the laser tube in a heat conduction way, the heat conduction substrate is integrally formed with a heat conduction sleeve penetrating through the laser tube mounting hole, the laser tube is connected in the heat conduction sleeve, when the temperature is more than 25 ℃, the laser tube is abutted with the laser tube mounting hole through the heat conduction sleeve, and the linear expansion coefficient of the radiator is smaller than that of the heat conduction sleeve. The observation of light is not dazzling, the diode irradiates and the electricity is saved.
However, the requirement of the green laser diode on the environment temperature is particularly high, the brightness of the green laser diode is reduced when the environment temperature is lower than 25 ℃, and the brightness of the green laser diode is also reduced when the environment temperature is higher than 30 ℃, so that heat dissipation and heating are considered when the green laser diode is used, particularly in winter, the environment temperature is relatively low, the temperature of some countries is near-25 ℃, products using the green laser diode are not bright at all, if a heating structure is not designed on the products to heat the products by the laser diode, the products cannot work, at present, two heating modes are provided for the laser diode, one heating mode is a mode of winding a heating belt on the laser diode and then installing the laser diode on a radiator to heat the laser diode, and the heating mode can cause poor heat dissipation of the laser diode when heat dissipation is needed, so that the green laser diode is seriously not suitable for heating. Another is to place a power resistor on the surface of the heat sink of the laser diode to heat the heat sink, and then transfer the heat to the laser diode through the heat sink, because the heat transfer of the heat sink surface to the laser tube green laser diode is very long when starting, the starting time in the low temperature environment (i.e. the time when the laser diode is heated to above 25 ℃ to normally emit light) is at least more than 30 minutes, i.e. the heating efficiency is low.
According to the technical scheme, the original power resistor is replaced by the patch resistor and is attached to the heat conducting plate, heat of the resistor is transmitted to the heat conducting plate, namely the heat conducting plate serves as a radiator of the resistor, the heat conducting plate is in heat conduction connection with the laser diode, so that the generated heat can be rapidly transmitted to the laser diode, and compared with the second mode, the time for heating the laser diode from-25 ℃ to 25 ℃ of a normal light-emitting machine is only 5-10 minutes (the existing time is 30 minutes). Meanwhile, when the laser diode is not heated, the influence of the existence of the heat conducting plate on the heat dissipation effect of the laser diode is small. When the temperature rises, the close fit between the small diode mounting hole with the thermal expansion effect and the laser diode is formed, so that good heat conduction can be carried out, and the heat dissipation effect can be high. The heat conduction effect between the laser diode and the radiator can be automatically reduced and the heat radiation can be automatically improved during heating.
Preferably, one side of the heat-conducting substrate, which is far away from the laser tube, is disconnected from the hole wall of the heating structure mounting hole. The heat during heating can mostly flow to the laser pipe and locate, plays the effect that improves the heating effect, and the hindrance when dispelling the heat is few.
Preferably, the chip resistor is arranged on one side of the heat conduction substrate far away from the laser tube. The heat transfer of the chip resistor to the heat-conducting plate can be ensured, and the existence of the chip resistor can not interfere with the heat transfer effect between the heat-conducting plate and the laser tube. Need heat the laser pipe when the temperature is less than 25 ℃, form clearance fit between laser pipe mounting hole and the laser pipe this moment under the effect of shrinkage, can prevent effectively that the heat of laser pipe from further running off and playing the effect that improves heating efficiency.
Preferably, one end of the heat conduction sleeve and one end of the radiator are in sealing butt joint with the sealing plate, the other end of the heat conduction sleeve and the other end of the radiator are in sealing connection through the annular liquid storage bag, a sealing cavity is formed among the heat conduction sleeve, the sealing plate, the radiator and the annular liquid storage bag, the sealing cavity is communicated with the annular liquid storage bag, and heat insulation liquid in the annular liquid storage bag can flow into the sealing cavity under the action of gravity or elastic contraction of the annular liquid storage bag. Because when being less than 25 ℃ the cold-shrinking effect can lead to producing the clearance and reducing the effect of heat conduction between heat conduction cover and the radiator and play the effect that improves the heating effect between heat conduction cover and the laser pipe mounting hole, adiabatic liquid fills and plays further improvement adiabatic effect and make the heating effect better in this clearance this moment. When the temperature is higher than 25 ℃ or 30 ℃ and heat dissipation is needed, the heat conduction sleeve and the laser tube mounting hole are tightly pressed together under the action of thermal expansion, and heat insulation liquid between the heat conduction sleeve and the laser tube mounting hole is extruded out in the pressing process and is stored in the annular liquid storage bag. The heating effect during heating can be further improved.
The invention has the following advantages: the generation of powder flowing lines can be reduced; the line contact powder coating of the fluorescent powder solution and the lamp tube can be realized.

The projected area of the light from the laser tube 72 projected onto the upper end, i.e., entrance end, of the light tunnel 78 is 0.1 square millimeters. The light from the light tunnel 78 and the laser tube 72 is concentric.
In use, when the amplitude of the vibration of the shaft of the reversing plug rotating motor 94 is within a predetermined range, the light emitted from the laser tube 72 can be continuously emitted from the light path 78 to the projection plate 77 for projection. If the light from the laser tube 72 is not projected onto the projection plate 77 or is interrupted, it indicates that the vibration is out of range, and that the bearings may be damaged by wear.
Referring to fig. 4, in use, the mixing blade 944 is mounted for rotation in a clockwise direction. The drain bar 924 is located on the front side of the via hole 922 in the rotation direction of the stirring blade. The distal end of the elastic brush 945 is provided with a hook 947 bent forward in the rotational direction of the stirring blade. The elastomeric bristles 945 can extend into the vias 922 as they pass through the vias 922.
Referring to fig. 5, a pull ring 925 is formed between the dirt bar 924 and the wall of the conical recess 921. The hook head of the elastomeric bristles 945 can hook into the pull ring 925 as they pass over the vented bar 924. The laser tube 72 is connected to the heat sink 71, i.e., to the housing of the reversing plug rotation motor 94 through the heat sink.
Referring to fig. 4 and 5, when in use, the reversing plug rotating motor 94 rotates to rotate the stirring blade 944, the elastic bristles 945 extend into the through holes 922 to hook out the dirt adhered and blocked in the through holes, the hook head hooks the pull ring 925 when passing through the dirt discharging rod 924, the dirt discharging rod 924 enables the hook head to stretch elastically to remove the dirt on the hook head and prevent the dirt from being brought into the next through hole, and the hook head moves away from the dirt discharging rod 924 and is bent again under the elastic action to form the hook head.
Referring to fig. 6, a heating structure 73 is also attached.
The heat sink 71 is provided with a laser tube mounting hole 711 and a heating structure mounting hole 712 which are communicated together. The laser tube mounting hole 711 is a circular hole. The heating structure mounting hole 712 is a rectangular hole. The laser tube mounting hole 711 is through with the heating structure mounting hole 712, and specifically, the laser tube mounting hole 711 is through in a manner that the circle thereof extends into the heating structure mounting hole 712, i.e., in an intersecting manner. The laser tube mounting hole 711 and the heating structure mounting hole 712 extend in the same direction, i.e., in the same depth direction, and both extend in the vertical direction.
The laser tube 72 is cylindrical. The laser tube 72 is provided with a power supply lead-in pin 721.
When the laser tube 72 is used, when the temperature of the laser tube 72 is higher than 25 ℃, the heating structure 73, that is, the chip resistor 732, is not electrified, and the radial variation of the heat conduction sleeve 734 is larger than that of the laser tube mounting hole 711, so that the heat conduction sleeve 734 and the laser tube mounting hole 711 are more tightly abutted together to conduct better heat conduction. The heat generated by the laser tube 72 is transferred to the heat sink 71 through the heat conductive sleeve and the heat conductive substrate 731, thereby dissipating the heat. When the temperature of the laser tube 72 is lower than 25 ℃, the chip resistor 732 is powered on, heat generated by the chip resistor 732 is transferred to the heat-conducting substrate 731, enters and is transferred to the laser tube 72 to heat the laser tube 72 to a temperature not lower than 25 ℃, and when the temperature is lower than 25 ℃, the radial reduction amount of the heat-conducting sleeve 734 is larger than that of the laser tube mounting hole 711, so that a gap is generated between the heat-conducting sleeve 734 and the laser tube mounting hole 711, the effect of reducing the heat transferred by the heat-conducting sleeve 734 to the heat radiator 71 is achieved, the heat transferred by the heat-conducting sleeve 734 and the heat-conducting sleeve 734 can be more fully transferred to the laser tube 72, and the effect of improving the heating effect is achieved
The third embodiment is different from the second embodiment in that:
referring to fig. 7, one end of the heat conductive jacket 734 and one end of the heat sink 71 are both sealingly abutted against the sealing plate 74, i.e., both the heat conductive jacket and the heat sink are slidable relative to the sealing plate 74. The other end of the heat conductive sleeve 734 and the other end of the heat sink 71 are hermetically connected together by an annular reservoir 75. The annular reservoir 75 is filled with a heat insulating liquid which keeps the annular reservoir 75 in an elastically expanded state. At temperatures below 25 ℃, a sealed cavity 76 is formed between the heat conducting sleeve 734, the sealing plate 74, the heat sink 71 and the annular reservoir 75. The sealed chamber 76 communicates with the annular reservoir 75.
In use the annular reservoir 75 is located above the sealed cavity 76 of the annular reservoir 75. When the temperature is lower than 25 ℃, the cold contraction action can cause a gap to be generated between the heat conduction sleeve and the laser tube mounting hole, so that the sealing cavity 76 is formed, at the moment, the heat insulation liquid in the annular liquid storage bag 75 flows into the sealing cavity 76 under the action of gravity and the elastic contraction of the annular liquid storage bag, the quantity of the heat conduction sleeve 734 transmitted to the heat radiator 71 is further reduced, and the heating effect is further improved. When the temperature is higher than 25 ℃ or 30 ℃ and heat dissipation is needed, the heat conduction sleeve and the laser tube mounting hole are tightly pressed together under the action of thermal expansion, so that the sealing cavity 76 disappears, and the heat insulation liquid in the sealing cavity 76 is squeezed back into the annular liquid storage bag 75 again to be stored.
