Description

Technical Field

[0001] This invention relates to the field of laser technology, and in particular to an embedded air purification module and a laser. Background Technology

[0002] In fields such as lasers and equipment, optical instruments and testing equipment, medical and pharmaceutical equipment, there are certain requirements for the air quality (such as humidity, suspended particulate matter, volatile organic compounds, etc.), overall appearance, and maintainability of the whole machine within a closed cavity. Air purification modules, as an air quality optimization device, are widely used in the above fields.

[0003] Existing air purification modules and devices are generally built into the product or externally mounted, and cannot be integrated into the product, which has the following disadvantages or problems:

[0004] 1. The purification module is built into the product. When it reaches the end of its service life or fails, it needs to be disassembled for repair. In some cases, on-site maintenance is not possible. This is time-consuming and labor-intensive, and it affects the product's sealing, humidity and cleanliness, which brings certain operational risks.

[0005] 2. Using external or attached purification modules will disrupt the overall appearance, occupy more external space, and bring uncertain risks of damage, such as bumps or collisions. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an embedded air purification module and laser that features strong sealing, excellent air purification effect, and easy maintenance.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0008] This application provides an embedded air purification module, including:

[0009] Air purification frame;

[0010] An air exchange component, disposed within the air purification frame, is used for the input and output of air to be purified to the filter unit;

[0011] The filter unit is disposed within the air purification frame and is used for filtering the air to be purified.

[0012] The connecting part is fixedly installed on the air purification frame and is used to connect the installation body, the input of the air to be purified from the installation body to the ventilation component, and the output of the purified air from the filter unit to the installation body.

[0013] The connecting part has two parts located on the same side of the air purification frame, and is respectively connected to the air inlet to be purified of the ventilation component and the purified air outlet of the filter unit.

[0014] Further specifying, in the above-mentioned embedded air purification module, the connecting part includes a connecting nozzle fixedly disposed on the air purification frame, a sealing ring and a plug are sequentially fixedly sleeved on the connecting nozzle, and a guide is fixedly disposed on the end of the connecting nozzle away from the air purification frame;

[0015] The guide member is conical, and the diameter of the end furthest from the air purification frame is smaller than the diameter of the end closest to the air purification frame.

[0016] Further specifying, in the aforementioned embedded air purification module, the filter unit includes:

[0017] Multiple compartments are provided within the air purification frame for filling filter material;

[0018] Ventilation holes are provided between two adjacent compartments to form a one-way airflow channel;

[0019] The compartment at the beginning of the one-way air flow channel is connected to the air outlet of the ventilation component, and the compartment at the end of the one-way air flow channel is connected to the corresponding connection part of the air outlet.

[0020] Further defining the aforementioned embedded air purification module, a plurality of the compartments are arranged in a linear array within the air purification frame, and the ventilation holes on the inner walls of the compartments on opposite sides are staggered to make the unidirectional airflow channel meander.

[0021] Further specifying, in the aforementioned embedded air purification module, the ventilation component includes:

[0022] An air pump is fixedly installed in the control cavity within the air purification frame;

[0023] A vibration damping unit is disposed between the inner wall of the control chamber of the air pump and the air purification frame, and is used for vibration damping and isolation when the air pump is in use.

[0024] The first air inlet pipe has one end connected to the air inlet end of the air pump and the other end connected to the corresponding connection part.

[0025] The first exhaust pipe has one end connected to the exhaust end of the air pump and the other end connected to the corresponding compartment.

[0026] Further specifying, in the aforementioned embedded air purification module, the ventilation component further includes:

[0027] The signal connection part is fixedly mounted on the air purification frame and located on the same side as the connection part, and is electrically connected to the air pump;

[0028] The signal connection part can be electrically connected to the power supply on the mounting body to supply power to the air pump.

[0029] Further specifying, the aforementioned embedded air purification module also includes a circulation component, the circulation component comprising:

[0030] The cylinder is provided in multiple parts and is fixedly installed on the inner wall of multiple compartments;

[0031] An air valve, connected to the outlet end of the cylinder and the air pump, is used to guide the air output by the air pump to the cylinder to supply air to the cylinder.

[0032] A flow guide is fixedly installed on the telescopic end of the cylinder, corresponding to the position of the vent hole on the compartment to guide the air flow in the compartment.

[0033] Further specifying, in the aforementioned embedded air purification module, the airflow guide includes:

[0034] The connecting beam is L-shaped and fixedly mounted on the telescopic end of the cylinder;

[0035] Two guide plates are provided, each located at one of the two arms of the connecting beam;

[0036] The guide block is fixedly installed at the ends of the two arms of the connecting beam;

[0037] The two guide plates are inclined to each other and correspond to the positions of the ventilation holes on the inner walls of opposite sides of the compartment. The inner wall of the compartment is provided with a guide groove that slides in cooperation with the guide slider.

[0038] This application also provides a laser, including a laser body and an embedded air purification module as described in any of the above claims, wherein the laser body has a slot with one end open for accommodating the embedded air purification module.

[0039] The laser body has a sealed cavity, and two positioning holes for insertion and mating with the connecting part are provided through the sealed cavity and the groove. The inner wall of the positioning hole is tapered to match the guide. A signal connection port for insertion and mating with the signal connection part is fixed on the inner wall of the groove.

[0040] When the embedded air purification module is installed in the slot, it is flush with the outer end face of the laser body. Two one-way valves with opposite directions are respectively provided in the two positioning holes. The one-way valves are used for one-way air flow between the laser body and the embedded air purification module.

[0041] Further specifying, in the aforementioned laser, the sealed cavity is provided with a second air inlet pipe and a second exhaust pipe respectively connected to two positioning holes, and the second exhaust pipe is provided with a filter;

[0042] The second air inlet pipe is used to output the air to be purified inside the laser body to the embedded air purification module, the second exhaust pipe is used to input the purified gas inside the embedded air purification module to the laser body, and the filter is used for secondary filtration of the flowing air.

[0043] This invention has at least the following beneficial effects:

[0044] 1. The gas to be purified is output to the filter unit through the ventilation component. The gas to be purified is purified by the filtration of the filter unit and purified air is output.

[0045] 2. Multiple compartments are set up within the air purification frame, that is, multi-level airflow channels are set up. Different purification materials with different functions are placed in each compartment within the channels, which can make the air purification more thorough.

[0046] 3. The staggered arrangement of vents on multiple compartments increases the airflow path within the compartments, thereby increasing the contact time between air and filter media, resulting in more thorough air filtration.

[0047] 4. The vibration damping unit is used to reduce and isolate vibration during the use of the air pump, thereby reducing the impact on other components and improving the service life and overall stability of the air pump.

[0048] 5. The gas in the compartment is guided by the circulation component. At the same time, when the cylinder is working, it will drive the guide to move in the direction of cylinder extension and retraction in the compartment, thereby agitating the granular filter media in the compartment, so that the filter media can fully absorb and filter the flowing gas.

[0049] 6. The air purification module is embedded in the laser body, which does not damage the overall appearance and does not occupy more external space. It is connected by the connector and positioning hole, which realizes the overall assembly and disassembly of the air purification module. This facilitates the timely replacement and maintenance of the filter and faulty parts inside the air purification module. The connector and positioning hole have a built-in guide and multi-level sealing design, which can realize blind insertion and self-alignment and movable insertion and removal. This achieves a high level of sealing of the purification channel and effectively prevents leakage. At the same time, the power supply and signal connection ports of the air pump also support blind insertion and movable insertion and removal. Power and air supply can be cut off at the same time as the air purification module is disassembled, which further improves the assembly and disassembly efficiency of the air purification module.

[0050] 7. One-way valves are installed in the two positioning holes respectively. When the air purification module is plugged in and out, the two positioning holes are automatically opened and closed. This prevents leakage, ensures the airtightness of the laser body, and prevents unpurified gas from entering, which greatly improves the stability and reliability of the air purification operation.

[0051] 8. A high-precision filter is installed on the air channel at one end of the laser body where the purified gas enters, serving as the final stage of reliable filtration and interception to ensure the air quality entering the optical cavity of the laser body. Attached Figure Description

Detailed Implementation

[0064] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0065] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0066] The embedded air purification module and laser provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0067] like Figures 1 to 6 As shown, this application embodiment provides an embedded air purification module, including an air purification frame, an air exchange component 140 and a filter unit disposed within the air purification frame.

[0068] The filter unit includes multiple compartments 170 disposed within the air purification frame and filter material filled in the compartments 170. Ventilation holes 120 are provided between two adjacent compartments 170, thereby forming a one-way airflow channel between the multiple compartments 170.

[0069] The air purification frame has an air inlet and an air outlet on the same side, and the compartment 170 at the end of the one-way air flow channel is connected to the air outlet on the air purification frame.

[0070] The ventilation assembly 140 includes an air pump 141. The air inlet end of the air pump 141 is connected to a first air inlet pipe 144, and the air outlet end is connected to a first exhaust pipe 145. The first air inlet pipe 144 is connected to the air inlet on the air purification frame, and the compartment 170 located at the beginning of the one-way air flow channel is connected to the first exhaust pipe 145.

[0071] In this embodiment, the above-mentioned embedded air purification module is used. The air pump 141 outputs the gas to be purified to the compartment 170. The gas to be purified is purified by the filter material in the compartment 170. The purified air is discharged through the one-way air flow channel formed by multiple compartments 170, thereby realizing the air purification process.

[0072] In a preferred embodiment, the vent 120 is provided with microporous polymer filter membranes of different diameters, and the filter material in the compartment 170 can be set as activated carbon, molecular sieve or other filtration or adsorption materials.

[0073] It is understandable that the filter media in compartment 170 is not limited to one or more of the above. Based on different filtration needs, different types of filter media can be set in different compartments 170 to achieve comprehensive purification of different air pollutants.

[0074] In this embodiment, the above-mentioned embedded air purification module is used, and a multi-level airflow channel is set in the base 111. Different purification materials with different effects are placed in each compartment 170 in the channel to make the air purification more thorough.

[0075] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, the air purification frame includes a base 111, and a control cavity 150 for accommodating the air exchange assembly 140 is provided in the base 111. Multiple compartments 170 are arranged in a linear array with their openings facing upwards.

[0076] The air purification frame also includes a cover plate 112 covering one side of the opening of the compartment 170. The cover plate 112 completely covers the multiple compartments 170 and a sealing gasket 130 is fixed between the cover plate 112 and the base 111. It can be understood that the sealing gasket 130 completely surrounds the opening of the multiple compartments 170 along the edge of the compartment 170, thereby achieving a complete seal of the compartments 170 under the clamping of the base 111 and the cover plate 112.

[0077] In a preferred embodiment, such as Figure 4 As shown, multiple compartments 170 are arranged in a linear array within the base 111. The ventilation holes 120 on the inner walls of the compartments 170 on opposite sides are staggered, making the one-way airflow channels between the multiple compartments 170 meander. Specifically, the ventilation holes 120 on the inner wall of the compartment 170 away from the control chamber 150 are located near the air inlet of the air purification frame, and the ventilation holes 120 on the inner wall of the compartment 170 near the control chamber 150 are located away from the air inlet of the air purification frame.

[0078] In this embodiment, the aforementioned embedded air purification module is used. When the air pump 141 is working, it draws in the air to be filtered through the first air inlet pipe 144 and outputs the air to the compartment 170 through the first exhaust pipe 145. The airflow is filtered by the filter material in the compartment 170. Since the ventilation holes 120 on the multiple compartments 170 are staggered, the airflow path in the compartment 170 is increased, thereby increasing the contact time between the air and the filter material, making the air filtration more thorough.

[0079] Of course, the ventilation holes 120 on the multiple compartments 170 only need to be staggered, and their specific arrangement is not limited to the one mentioned above.

[0080] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, three compartments 170 are arranged in a linear array within the base 111, and the three compartments 170 are filled with filter media of different functions.

[0081] It is understandable that the number of compartments 170 within the base 111 is determined based on the module volume and purification requirements. For example, the number can also be set to four, five, or six, etc., which will not be elaborated here.

[0082] In a preferred embodiment, such as Figure 2 As shown, two connecting parts 160 are fixedly provided at the air inlet and air outlet positions on the outside of the air purification frame. Specifically, one connecting part 160 is fixedly provided at the corresponding position of the base 111 with respect to the control cavity 150, and the other connecting part 160 is fixedly provided at the corresponding position of the base 111 with respect to the compartment 170 on the side furthest from the control cavity 150.

[0083] It is understandable that the connecting part 160 is used for the input of air to be purified to the purification module and the output of purified air. At the same time, the connecting part 160 is also used for the connection with the mounting body, and the mounting body is provided with a connection structure that cooperates with the connecting part 160.

[0084] In a preferred embodiment, such as Figure 3As shown, the connecting part 160 includes a connecting nozzle 161 fixedly mounted on the base 111. A sealing ring 162 and a plug seal 163 are sequentially fixedly mounted on the connecting nozzle 161. A guide member 164 is threadedly fixedly mounted on the end of the connecting nozzle 161 away from the base 111.

[0085] The guide 164 is conical, and the diameter of the end away from the base 111 is smaller than the diameter of the end near the base 111. When the embedded air purification module is connected to the mounting body, the connecting part 160 cooperates with the connecting structure on the mounting body to achieve a fixed connection between the two. The sealing ring 162 and the plug seal 163 are used for air sealing between the air purification module and the mounting body, while the conical structure of the guide 164 is mainly used for guiding the cooperation between the connecting part 160 and the connecting structure on the mounting body.

[0086] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, the ventilation assembly 140 also includes a vibration damping unit 142 disposed between the air pump 141 and the inner wall of the control chamber 150. The vibration damping unit 142 is used to dampen and isolate the air pump 141 during use, reduce the impact on other components, and improve the service life of the air pump 141 and the overall stability of the machine.

[0087] It is understandable that the structure of the damping unit 142 can be varied. For example, a spherical support made of flexible material can be provided at the bottom of the air pump 141, or an elastic damping element can be provided between the bottom of the air pump 141 and the inner wall of the corresponding side of the control cavity 150. As long as the overall vibration of the air pump 141 can be reduced, it will not be described in detail here.

[0088] In a preferred embodiment, such as Figure 1 As shown, the ventilation assembly 140 also includes a signal connection part 143 fixedly mounted on the base 111 and located at the corresponding position of the control chamber 150. The signal connection part 143 is on the same side as the connection part 160 and is connected to the air pump 141.

[0089] It is understandable that the signal connection part 143 is mainly used for power supply of the air pump 141. The mounting body is provided with a power supply component that cooperates with the signal connection part 143. When the embedded air purification module is connected to the mounting body, the signal connection part 143 is electrically connected to the power supply component on the mounting body, thereby realizing the power supply of the air pump 141.

[0090] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, the air purification frame also includes a decorative panel 113 fixedly mounted on the base 111.

[0091] Understandably, the decorative panel 113 is mainly used to ensure the integrity between the embedded air purification module and the main body after installation, and its specific shape matches the installation structure on the main body.

[0092] In a preferred embodiment, such as Figure 5 As shown, it also includes a circulation assembly, which is disposed in the compartment 170 and includes a cylinder 191, a valve 192 and a guide 180 connected to the extension end of the cylinder 191. The valve 192 is connected to the first exhaust pipe 145 and the cylinder 191 to guide the air output by the air pump 141 to the cylinder 191.

[0093] It is understandable that the cylinder 191 is provided in multiple ways and is fixedly installed on the inner wall of multiple compartments 170. The guide 180 corresponds to the vent hole 120 on the compartment 170, thereby realizing the guidance of gas in the compartment 170.

[0094] At the same time, when the cylinder 191 is working, it will drive the guide 180 to move in the extension and retraction direction of the cylinder 191 within the compartment 170, thereby stirring the granular filter media in the compartment 170 so that the filter media can fully absorb and filter the flowing gas.

[0095] In a preferred embodiment, such as Figure 5 As shown, the circulation assembly also includes a transmission pipe 193 for connecting the air valve 192 and the cylinder 191. One end of the transmission pipe 193 is connected to the air valve 192, and the other end passes through multiple compartments 170 and is connected to the cylinder 191 respectively, thereby supplying air and power to the cylinder 191.

[0096] The passage between the transmission pipe 193 and the compartment 170 is sealed with a sealing material to ensure the airtightness of the compartment 170. It is understood that the transmission pipe 193, which supplies air and electricity to the cylinder 191, can also be connected to the air valve 192 from outside the compartment 170, which can further improve the airtightness inside the compartment, but will affect the overall integrity of the purification module.

[0097] In a preferred embodiment, such as Figure 5 , Figure 6 As shown, the flow guide 180 includes an "L"-shaped connecting beam 181. Guide plates 182 are fixedly provided at the ends of both arms of the connecting beam 181. The two guide plates 182 correspond to the positions of the ventilation holes 120 on the inner walls of opposite sides of the compartment 170.

[0098] The two guide plates 182 are set at a certain angle. Specifically, on the one-way air flow channel path in the compartment 170, the guide plate 182 corresponding to the air inlet vent 120 guides the air to the guide plate 182 corresponding to the air outlet vent 120, and the guide plate 182 corresponding to the air outlet vent 120 guides the air to the corresponding air outlet vent 120, thereby realizing the guided flow of air in the compartment 170.

[0099] It is understood that the configuration of the flow guide 180 is not limited to the one mentioned above. It is mainly used to guide the airflow in the compartment 170 and can stir the filter material in the compartment 170 by the drive of the cylinder 191. It can also be configured as any form of aerodynamic structure, which will not be described in detail here.

[0100] like Figure 5 , Figure 6 As shown, the flow guide 180 also includes a guide slider 183 fixedly disposed at the ends of the two arms of the connecting beam 181. The inner wall of the compartment 170 is provided with a guide groove that slides in cooperation with the guide slider 183. The length direction of the guide groove is the same as the extension and retraction direction of the cylinder 191. When the cylinder 191 drives the flow guide 180 to move, the guide slider 183 on the flow guide 180 slides in the guide groove, thereby ensuring the smoothness of the movement of the flow guide 180.

[0101] Understandably, the width of the guide groove is set to be smaller than the particle diameter of the filter media, so as to prevent the filter media from getting stuck in the guide groove and affecting the normal movement of the guide component 180.

[0102] like Figures 7 to 10 As shown, this application embodiment provides a laser, including a laser body 200 and an air purification module 100 embedded in the laser body 200, wherein the air purification module 100 adopts the above-mentioned embedded air purification module.

[0103] like Figure 8 , Figure 9 As shown, the laser body 200 includes a groove 210 with one end open for accommodating the air purification module 100. When the air purification module 100 is installed in the groove 210, the decorative panel 113 is flush with the outer surface of the laser body 200, and the connecting part 160 is located on the end face of the base 111 away from the decorative panel 113.

[0104] The laser body 200 is also provided with a first sealing cavity 220. The bottom wall of the groove 210 and the first sealing cavity 220 are provided with positioning holes 240 corresponding to the positions of the two connecting parts 160. When the air purification module 100 is installed in the groove 210, the two connecting parts 160 are respectively engaged with the two positioning holes 240. The inner wall contour of the positioning hole 240 is tapered and matches the guide 164, so as to guide and position the connecting part 160 when it is inserted into the positioning hole 240.

[0105] The bottom wall of the recess 210 is also fixedly provided with a signal connection port 230 corresponding to the position of the signal connection part 143. When the air purification module 100 is installed in the recess 210, the signal connection part 143 and the signal connection port 230 are plugged in to achieve electrical connection between the signal connection part 143 and the signal connection port 230, thereby realizing power supply to the air pump 141.

[0106] When installing the air purification module 100, the air purification module 100 is inserted into the groove 210, the outer end face of the base 111 is in contact with the inner wall of the groove 210, and the two connecting parts 160 are respectively inserted into the two positioning holes 240. The tapered structure of the positioning hole 240 and the guide 164 guides when they are connected. When the connecting part 160 is fully connected to the positioning hole 240, the plug seal 163 and the sealing ring 162 are deformed under pressure to achieve a seal between the positioning hole 240 and the connecting part 160. At the same time, the signal connection port 230 is electrically connected to the signal connection part 143 to supply power to the air pump 141.

[0107] After the air purification module 100 is installed, the air to be purified in the first sealed cavity 220 is purified by the air pump 141 through the corresponding positioning hole 240 and the connecting part 160 and output to the compartment 170. The purified air is then circulated back into the first sealed cavity 220 through the corresponding connecting part 160 and the positioning hole 240, thereby realizing the air filtration and circulation in the first sealed cavity 220.

[0108] In this embodiment, the aforementioned laser is used, and the air purification module 100 is embedded in the laser body 200, which does not damage the overall appearance and does not occupy more external space. At the same time, the connection is achieved through the plug-in cooperation of the connecting part 160 and the positioning hole 240, realizing the overall assembly and disassembly of the air purification module 100. This facilitates the timely replacement and maintenance of the filter material and faulty parts inside the air purification module 100. The connecting part 160 and the positioning hole 240 have a built-in guide and multi-level sealing design, which can realize blind insertion self-alignment and movable plug-in, achieving a high level of sealing of the purification channel and effectively preventing leakage. At the same time, the power supply and signal connection port 230 of the air pump 141 also supports blind insertion and movable plug-in, realizing power and gas cut-off at the same time as disassembling the air purification module 100, further improving the assembly and disassembly efficiency of the air purification module 100.

[0109] In a preferred embodiment, a first one-way valve is provided in the positioning hole 240 for outputting the air to be purified into the air purification module 100, and a second one-way valve is provided in the positioning hole 240 for inputting the purified air into the laser body 200. The first one-way valve and the second one-way valve are mainly used for one-way airflow.

[0110] Specifically, for the first one-way valve, the flow channel is only opened for the air flowing from the laser body 200 to the air purification module 100, and the flow channel is closed for the air flowing from the air purification module 100 to the laser body 200; for the second one-way valve, the flow channel is only opened for the air flowing from the air purification module 100 to the laser body 200, and the flow channel is closed for the air flowing from the laser body 200 to the air purification module 100.

[0111] When the air purification module 100 is removed and the filter material in the compartment 170 is replaced, the air purification module 100 is pulled out of the groove 210. At this time, the connecting part 160 and the positioning hole 240, the signal connecting part 143 and the signal connecting port 230 are separated simultaneously. After separation, the first one-way valve and the second one-way valve in the positioning hole 240 automatically seal, so that the air purification module 100 can be automatically disconnected from the laser body 200 without any extra operation, ensuring the airtightness of the whole machine and ensuring that each purification pipeline is not polluted by external bad air.

[0112] In this embodiment, the laser described above is used, and one-way valves are respectively installed in the two positioning holes 240. When the air purification module 100 is plugged in and out, the two positioning holes 240 are automatically opened and closed. This prevents leakage, ensures the sealing of the laser body 200, and prevents unpurified gas from entering, greatly improving the stability and reliability of the air purification operation.

[0113] In a preferred embodiment, such as Figure 9As shown, the first sealing cavity 220 is provided with a second air inlet pipe 250 and a second exhaust pipe 270 respectively connected to two positioning holes 240. The second air inlet pipe 250 corresponds to the position of the air pump 141 on the air purification module 100 and is used to output the air to be purified in the laser body 200 to the air purification module 100. The second exhaust pipe 270 is used to input the purified gas in the air purification module 100 to the laser body 200.

[0114] The second exhaust pipe 270 is equipped with a filter 260, which uses a high-precision filtration device to achieve secondary filtration of the purified air, thereby making the air inside the laser body 200 more purified.

[0115] The second exhaust pipe 270 is also equipped with a polymer ventilation membrane, which is used to perform high-precision filtration on the air flowing through the second exhaust pipe 270 to ensure the final air purification effect.

[0116] In this embodiment, the laser described above is used, and a high-precision filter 260 and a microporous polymer ventilation membrane are set on the air channel at one end of the laser body 200 after purification, so as to serve as the last stage of reliable filtration and interception, ensuring the air quality entering the optical cavity inside the laser body 200.

[0117] In a preferred embodiment, such as Figure 9 , Figure 10 As shown, the laser body 200 is also provided with a second sealing cavity 280. The second air inlet pipe 250 and the second exhaust pipe 270 are connected to the second sealing cavity 280 at the ends away from the corresponding positioning holes 240. The first sealing cavity 220 serves as the wiring cavity for the second air inlet pipe 250 and the second exhaust pipe 270, while the second sealing cavity 280 serves as the optical cavity for high-quality air input.

[0118] Two transition nozzles 290 are fixedly embedded on the inner wall of the second sealing cavity 280 near the first sealing cavity 220. The second air inlet pipe 250 and the second exhaust pipe 270 are respectively connected to the two transition nozzles 290 on the side away from the corresponding positioning hole 240.

[0119] Understandably, the transition nozzle 290 is mainly used to absorb the air to be purified in the second sealing cavity 280 and to disperse and release the purified air. The two transition nozzles 290 need to maintain a certain distance to ensure the circulation of air in the second sealing cavity 280 and improve the air purification effect of the second sealing cavity 280.
