because the cooling part 4 is cylindrical structure, and annular liquid storage cavity has been seted up to cooling part rear end face for the coolant liquid in the annular liquid storage cavity can closely with cooling part 4 outer wall contact, thereby after cooling part 4 outer wall and annular fin 402 obtain the effect of dispelling the heat of blowing, its inside coolant liquid must obtain the effect of dispelling the heat, in addition, as shown in figure 9, can only connect the annular liquid storage cavity structure on the cooling part 4 when seeing, and then can make the inside entering of cooling part 4 have the thermal coolant liquid obtain the effect of cooling down, so cyclic operation, thereby just can make the inside effect of cooling down of laser housing 2.
When the loss of the cooling liquid in the cooling part 4 is serious in the use process, firstly the floating plate 901 moves downwards under the action of gravity of the balancing weight 907 while the liquid level of the cooling liquid is lowered, then simultaneously drives the first rack 902 to move downwards, and then drives the second rack 903 to synchronously move downwards through two gears on the transmission shaft 904, so that the second rack 903 drives the L-shaped pressing rod 905 to move downwards, and then the button on the pressing switch 906 is pressed through the bottom end surface of the L-shaped pressing rod 905, so that the small audible and visual alarm 8 starts to give an alarm, and at the moment, a worker can find the reason of alarm through the sent alarm sound and alarm light, so that the phenomenon of too little cooling liquid in the cooling part 4 can be timely perceived.
Finally, it should be noted that the present invention is generally described in terms of a/a pair of components, such as the location of each component and the mating relationship therebetween, however, those skilled in the art will appreciate that such location, mating relationship, etc. are equally applicable to other components/other pairs of components.
The foregoing is merely exemplary embodiments of the present invention and is not intended to limit the scope of the invention, which is defined by the appended claims.
