In order to facilitate the description, in the utility model, only the laser hand tool applied to the laser treatment instrument is taken as an example for description, and the principle of the laser hand tool applied to other types of equipment is substantially the same as that applied to the laser treatment instrument, which will not be described one by one.

[0038] Please refer to Figure 1 , Figure 1For the structure diagram of the laser hand tool in an embodiment of the utility model, the laser hand tool includes laser assembly 1, focusing assembly 2, smoke blowing assembly 3 and smoke suction assembly 4: laser assembly 1 includes laser seat 11; focusing assembly 2 is connected with laser seat 11, focusing assembly 2 and laser seat 11 form the hollow structure, it is the laser passage a for supplying laser; smoke blowing assembly 3 is connected with laser seat 11 and / or focusing assembly 2, smoke blowing assembly 3 is equipped with first through-hole 31, and the both ends of first through-hole 31 are blowing end and air inlet end respectively, blowing end is towards laser passage a, and air inlet end is used to connect with air pump; smoke suction assembly 4 is connected with laser seat 11, and smoke suction assembly 4 is equipped with second through-hole 41, and the both ends of second through-hole 41 are smoke suction end and smoke exhaust end respectively, and the side wall of laser seat 11 and focusing assembly 2 is equipped with the flow channel b that is connected; smoke suction end is connected with the bottom of laser passage a through flow channel b, and smoke exhaust end is used to connect with the air extraction equipment (not shown in the drawing).

[0039] Specifically, when the laser hand tool works, the side of focusing assembly 2 away from laser seat 11 is attached to the area to be treated, laser enters laser seat 11, and enters laser passage a through laser seat 11, the air extraction equipment is started, and forms negative pressure suction, and the smoke formed is sucked into flow channel b, and enters second through-hole 41 of smoke suction assembly 4 through flow channel b, and is finally discharged through the smoke exhaust end of smoke suction assembly 4, which can suck away the smoke formed during laser irradiation, avoiding the smoke floating around the hand tool; in order to avoid the smoke contacting and polluting the lens in laser seat 11, the air pump is started, the air pump pumps air into first through-hole 31 of smoke blowing assembly 3, the air passes through first through-hole 31, and blows towards the smoke from the blowing end of smoke blowing assembly 3, which can disperse the smoke, avoid the smoke diffusing towards the lens, and avoid the smoke polluting the lens.

[0040] At the same time, by connecting smoke suction assembly 4 with laser seat 11, the smoke outlet pipeline related to smoke suction assembly 4 can be arranged together with the pipeline on laser seat 11, avoiding the pipeline being arranged disorderly.

[0041] It should be understood that smoke suction assembly 4 can be a smoke suction joint, a smoke exhaust joint, etc.; smoke blowing assembly 3 can be a smoke blowing nozzle, a smoke blowing nozzle, etc.

[0042] In order to suck the smoke into flow channel b, in one of the embodiments, a plurality of smoke suction holes b22 are formed on the side of focusing assembly 2 towards laser passage a, the plurality of smoke suction holes b22 are distributed along the circumference of laser passage a, and the smoke suction holes b22 are connected with flow channel b. It should be understood that the plurality of smoke suction holes b22 can also be distributed along the axial direction of focusing bracket 21.

[0043] When smoke suction assembly 4 sucks the smoke, the smoke can enter flow channel b through smoke suction hole b22, by arranging a plurality of smoke suction holes b22, the plurality of smoke suction holes b22 can all suck the smoke, which can suck the smoke from multiple directions, avoiding the smoke diffusing.

[0044] It should be understood that the smoking hole b22 can be various types of various shaped holes, in particular, as shown in Figure 3 and Figure 5 , in one embodiment, the smoking hole b22 includes an air inlet groove b221 extending along the circumference of the laser channel a, and a fixed hole b222 communicating with the air inlet groove b221, the fixed hole b222 extending along the axis of the laser channel a and communicating with the flow channel b.

[0045] The air inlet groove b221 is arranged along the circumference of the laser channel a, which increases the area of the smoking hole b22 along the circumference of the laser channel a, so that the smoke can enter the air inlet groove b221 along the circumference of the laser channel a, and the area of the smoke absorbing hole b22 is increased, and by arranging the fixed hole b222, the fixed hole b222 communicates with the flow channel b, and the smoke sucked into the air inlet groove b221 can be introduced into the flow channel b.

[0046] It should be understood that the air inlet groove b221 can be arranged on either side of the focusing bracket 21, in particular, as shown in Figure 2 and Figure 4 , in one embodiment, the air inlet groove b221 is arranged at the end of the focusing bracket 21 away from the laser seat 11.

[0047] Through the above arrangement, the air inlet groove b221 is arranged as close as possible to the smoke forming area, so that the suction force acts more closely on the formed smoke, and the smoke adsorption effect is enhanced.

[0048] In order to realize the communication between the smoking end of the smoking assembly 4 and the bottom of the laser channel a, for this purpose, as shown in Figure 3 and Figure 4 , in one embodiment, the flow channel b includes a first air channel b1 opened in the laser seat 11 and a second air channel b2 arranged in the focusing assembly 2, the first air channel b1 communicates with the smoking end of the smoking assembly 4, and the second air channel b2 communicates with the bottom of the laser channel a.

[0049] By arranging the first air channel b1 and the second air channel b2 in communication, the communication between the smoking end of the smoking assembly 4 fixed to the laser seat 11 and the bottom of the laser channel a is realized.

[0050] As shown in Figure 3 and Figure 4 , in one embodiment, the flow channel b further includes a third air channel b3, the third air channel b3 is an annular air channel formed between the laser seat 11 and the focusing assembly 2, and the third air channel b3 respectively communicates with the first air channel b1 and the second air channel b2.

[0051] By setting the annular third air channel b3, firstly, the communication between the first air channel b1 and the second air channel b2 is realized, and secondly, the third air channel b3 is annular, so that when the focusing assembly 2 is connected with the laser seat 11, the third air channel b3 does not need to be aligned with the second air channel b2. After the focusing assembly 2 is connected with the laser seat 11, the annular third air channel b3 can realize the communication between the first air channel b1 and the second air channel b2, thereby reducing the assembly difficulty.

[0052] As shown in Figure 3 and Figure 4 , in one of the embodiments, the focusing assembly 2 includes a focusing bracket 21, a bracket seat 22 and a lens seat 23. The bracket seat 22 is arranged between the focusing bracket 21 and the laser seat 11, and the lens seat 23 is connected with the bracket seat 22 and the laser seat 11. The second air channel b2 includes a communication air channel b21 arranged on the bracket seat 22 and a smoke suction hole b22 arranged on the focusing bracket 21.

The fourth air channel b23 is an annular air channel formed between the focusing bracket 21 and the bracket seat 22. The fourth air channel b23 is in communication with the communication air channel b21 and the smoke suction hole b22, respectively.

[0054] By setting the annular fourth air channel b23, one side of the fourth air channel b23 is in communication with the plurality of smoke suction holes b22, and the other side is in communication with the communication air channel b21, thereby realizing the communication between the plurality of smoke suction holes b22 and the communication air channel b21.

The other end of the second communication hole b212 is in communication with the fourth air channel b23.

[0056] Since the outer diameter of the third air channel b3 is smaller than the inner diameter of the fourth air channel b23, when the third air channel b3 and the fourth air channel b23 are communicated, a through hole can be used to directly communicate the third air channel b3 and the fourth air channel b23. When the third air channel b3 and the fourth air channel b23 are communicated in a staggered manner, the through hole also needs to have sufficient communication area. Therefore, the through hole needs to be made larger in size. After the size of the through hole is increased, in order to avoid the fact that the support seat 22 has a weak point at the through hole, which leads to the increase of the size of the support seat 22, the size of the support seat 22 is increased. In the embodiment, the communication air channel b21 is provided as two first communication holes b211 and second communication holes b212 arranged in a staggered manner. The first communication hole b211 and the second communication hole b212 respectively communicate the third air channel b3 and the fourth air channel b23 in a staggered manner. Through the staggered communication of the first communication hole b211 and the second communication hole b212, the third air channel b3 and the fourth air channel b23 are communicated. There is no need to open a larger size through hole.
