Description
Technical Field
[0001] This utility model belongs to the field of laser technology, specifically relating to a window mirror blowing device and a laser. Background Technology
[0002] In practical applications of lasers, the laser window mirror is frequently exposed to the processing environment. With prolonged exposure, dust and water vapor accumulate on the outer surface of the mirror. Under laser irradiation, the mirror is easily damaged, especially with ultraviolet and deep ultraviolet lasers, which require a very high level of cleanliness. Therefore, the window mirror generally needs to be cleaned by blowing.
[0003] A Brewster angle window is a special optical window element primarily used in laser systems, optical instruments, and other applications requiring polarization control and low-loss transmission. The installation angle of a Brewster angle window must be determined based on the specific application and the refractive index of the medium. The core principle is to ensure that incident light reaches the window surface at a Brewster angle. For example, when light travels from air to glass, the Brewster angle is approximately 56.3°. Therefore, Brewster angle window lenses generally need to be installed at an angle. However, existing window lens cleaning devices are primarily designed for vertically mounted lenses and are not suitable for cleaning tilted Brewster angle windows. Utility Model Content
[0004] The purpose of this invention is to provide a window mirror blowing device and a laser, suitable for blowing and cleaning Brewster corner window mirrors.
[0005] This application provides a window mirror air blowing device, comprising: A window lens mount includes a laser emitting end and a laser incident end for mounting on a laser; the interior of the window lens mount is provided with a first laser channel connecting the laser emitting end and the laser incident end; a lens is obliquely disposed on the laser incident end to cover the entrance of the first laser channel; multiple airflow channels are provided on the outer periphery of the first laser channel; the air inlets of the airflow channels are located on the outer periphery of the exit of the first laser channel, and the air outlets are located on the inner wall of the entrance of the first laser channel and face the lens surface; and An air supply assembly, connected to the air inlet, is used to blow air into the airflow channel.

[0007] In one embodiment of this application, the angle between the airflow channel and the axis of the first laser channel is smaller than the angle between the lens and the axis of the first laser channel.
[0008] In one embodiment of this application, the gas supply assembly includes: An air supply base, internally equipped with a second laser channel corresponding to the first laser channel; the end face of the air supply base facing the window mirror mount is provided with annular grooves communicating with each air inlet; and The gas supply channel is connected to the annular groove.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] This application provides a window mirror air blowing device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.
[0023] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the window mirror air blowing device includes: A window lens mount 1 includes a laser emitting end 101 and a laser incident end 102 for mounting on a laser. The window lens mount 1 has a first laser channel 11 connecting the laser emitting end 101 and the laser incident end 102. A lens 3 is obliquely disposed on the laser incident end 102 to cover the entrance of the first laser channel 11. Multiple airflow channels 12 are disposed around the outer periphery of the first laser channel 11. The air inlets 121 of the airflow channels 12 are located around the outlet of the first laser channel 11, and the outlets 122 are located on the inner wall of the entrance of the first laser channel 11 and face the surface of the lens 3. The air supply component 2 is connected to the air inlet 121 and is used to blow air into the airflow channel 12.
[0024] In this embodiment, the multiple air inlets 121 can be arranged in a circumferential array around the outlet of the first laser channel 11; the airflow channels 12 are inclined from the air inlets 121 to the air outlets 122; the multiple airflow channels 12 are inclined around the first laser channel 11, and the air outlets 122 are all facing the surface of the lens 3, so that the surface of the lens 3 can be directly blown.
[0025] In some embodiments, optionally, a lens mounting portion 103 is provided protruding on the end face of the laser incident end 102.
[0026] In some embodiments, the lens mounting portion 103 can extend into the housing of the laser, such that the upper surface of the lens 3 is located inside the laser. The laser is generally a sealed cavity with good cleanliness and dryness. Because the laser is assembled in a cleanroom and contains desiccant or a circulating drying system, there is no risk of damage to the upper surface of the lens 3.
[0027] In some embodiments, the lens 3 is positioned at a Brewster angle to the laser, and the lens may be uncoated, especially in deep ultraviolet models, where the absence of coating can reduce the risk of coating damage.
[0028] In some embodiments, since the lens 3 is positioned at a Brewster angle with the laser, in order to allow all air outlets 122 to directly blow on the surface of the lens 3, optionally, the angle between the airflow channel 12 and the axis of the first laser channel 11 is smaller than the angle between the lens 3 and the axis of the first laser channel 11.
[0029] In some embodiments, the air supply assembly 2 may optionally include: an air supply base 21, which has a second laser channel 211 corresponding to the first laser channel 11 inside; an annular groove 212 communicating with each air inlet 121 is provided on the end face of the air supply base 21 facing the window mirror base 1; and an air supply channel 22 communicating with the annular groove 212.
[0030] In this embodiment, the annular groove 212 can distribute the gas delivered by the gas supply channel 22 to each airflow channel 12.
[0031] Optionally, the air supply channel 22 is disposed inside the air supply seat 21. Of course, in some embodiments, the air supply channel 22 may be an air pipe communicating with the annular groove 212.
[0032] Optionally, the air inlet end of the air supply channel 22 is provided with a connector 221, which can facilitate connection to an air source.
[0033] Optionally, a first sealing ring 13 is provided on the laser emitting end 101; the first sealing ring 13 is located on the outer periphery of the annular groove 212. The first sealing ring 13 can be used to seal the mating gap between the laser emitting end 101 and the gas supply seat 21.
[0034] Furthermore, a second sealing ring 14 is provided on the laser incident end 102; the second sealing ring 14 is located on the outer periphery of the lens mounting part 103. The second sealing ring 14 can be used to seal the mating gap between the laser incident end 102 and the outer wall of the laser housing.
[0035] See Figure 1 Optionally, the outer wall of the inlet of the second laser channel 211 is wedge-shaped and protrudes from the surface of the gas supply seat 21; the inner wall of the outlet of the first laser channel 11 is funnel-shaped for insertion into the inlet of the second laser channel 211. This facilitates the alignment and assembly of the first laser channel 11 and the second laser channel 211.
[0036] In one embodiment, after the gas enters the annular groove 212 through the gas supply channel 22, it enters the corresponding airflow channels 12 and is then discharged from the gas outlet 122 onto the surface of the lens 3, directly cleaning the surface of the lens 3. Finally, it is discharged sequentially through the first laser channel 11 and the second laser channel 211. This achieves uniform airflow conduction, a more complete cleaning coverage area for the lens 3, and a more thorough cleaning.
[0037] See Figure 4 and Figure 5 An embodiment of this application also provides a laser, including: a housing 100 having a laser outlet 110 thereon; and a window mirror blowing device 200 as described above, installed at the laser outlet 110.
[0038] In one embodiment, during assembly, the lens 3 can be assembled first, and then the lens mounting part 103 can be inserted into the laser outlet 110 on the housing 100 so that the upper surface of the lens 3 is located inside the housing 100; then the window lens mount 1 can be fixed on the housing 100 so that the laser incident end 102 is sealed with the outer side of the housing 100; finally, the air supply seat 21 can be fixed on the laser emitting end 101 of the window lens mount 1 to complete the assembly.
[0039] In summary, the air blowing device for the window mirror of this utility model has a compact structure, few parts, and is easy to process, manufacture, and control costs; the Brewster lens has no risk of coating damage, and the angled airflow channel can effectively solve the problem of difficulty in blowing air when the Brewster lens is installed deep; the design of the annular groove and multiple airflow channels makes the cleaning effect more comprehensive.
