In some embodiments, the light blocking member 30 is detachably connected to the emitting member 10, which facilitates cleaning and maintenance of the device, for example, when the light blocking member 30 and the light collecting hole 311 need to be cleaned, only the light blocking member 30 needs to be detached from the emitting member 10 for individual cleaning, which is very convenient, and on the other hand, the existing emitting member 10 is also conveniently modified, that is, only the light blocking member 30 needs to be installed on the modified emitting member 10, which is simple in operation and low in cost.
Referring to fig. 2 to 4, as an implementable manner in which the light blocking member 30 is detachably coupled to the emission member 10, the emission member 10 is provided in a cylindrical shape, and the light emitting hole 11 is provided at one end of the emission member 10; the light blocking member 30 further includes a connecting cylinder 32, the connecting cylinder 32 is detachably connected to the emitting member 10, if the connecting cylinder 32 is sleeved on the emitting member 10, the light blocking plate 31 is disposed at one end of the connecting cylinder 32 and is used for sealing the opening of the connecting cylinder 32, when the connecting cylinder 32 is sleeved on the emitting member 10, the light blocking plate 31 is just covered on the light emitting hole 11 of the emitting member 10, and at this time, the light emitted from the light emitting hole 11 can only be emitted through the light collecting hole 311 of the light blocking plate 31. The light barrier 31 and the connection cylinder 32 may be integrally or separately provided.
Referring to fig. 2 to 4 again, as a way of detachably connecting the connection cylinder 32 and the emission part 10, an inner wall of the connection cylinder 32 is provided with an inner thread (not shown), and an outer wall of the emission part 10 is provided with an outer thread 12 matching with the inner thread.

In practical application, an internal thread can be machined on the inner wall of the connecting cylinder 32, and then the external thread 12 is machined on the outer wall of the launching component 10 again, so that the existing equipment is convenient to modify, the launching component 10 with the external thread 12 can be directly selected again, and then the corresponding internal thread is machined on the inner wall of the connecting cylinder 32.
Referring to fig. 5 and 6, as another way of detachably connecting the connection cylinder 32 and the launching member 10, a hanging claw 33 is disposed at an end of the connection cylinder 32 away from the light barrier 31, the hanging claw 33 has a certain elasticity along a radial direction of the connection cylinder 32, a hanging groove 13 is disposed on an outer wall of the launching member 10, and the hanging claw 33 is used for being clamped in the hanging groove 13 to fix the connection cylinder 32.
When it is desired to mount the coupling cylinder 32 to the striking member 10, it is only necessary to push the coupling cylinder 32 in a direction close to the striking member 10 while the hanging claws 33 slide on the outer wall of the striking member 10, and push the coupling cylinder 32 continuously until the hanging claws 33 are caught in the hanging grooves 13, thereby fixing the coupling cylinder 32 to the striking member 10. When the connection cylinder 32 needs to be detached from the launching component 10, the hanging claw 33 is only required to be firstly clamped and moved out of the hanging groove 13, then the connection cylinder 32 is pushed in the direction away from the launching component 10, at this time, the hanging claw 33 slides on the outer wall of the launching component 10, and the connection cylinder 32 is continuously pushed until the hanging claw 33 is separated from the outer wall of the launching component 10, so that the connection cylinder 32 is detached from the launching component 10, the structure is simple, and the operation is convenient.
