For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural.

[0039] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0040] Please refer to FIG1 , which is a flow chart of a control method for a laser engraving machine according to an embodiment of the present application. The laser engraving machine according to this embodiment is equipped with a protective cover. The control method includes the following steps:

[0041] Step 101: In response to protection detection information, perform a closure detection on the protection cover at least at a first position.

[0042] In some embodiments, the laser engraving machine includes a control panel. The user operates buttons on the control panel to cause the control panel to send protection detection information to the main control module of the laser engraving machine. The main control module performs closure detection on the protective cover in response to the protection detection information.

[0043] In some embodiments, the protective cover includes a protective lid and a bottom frame. The protective lid is slidable to open and close the protective cover. The first position includes a closed joint between the protective lid and the bottom frame. Detecting the closure of the protective cover at least in the first position includes detecting the closure of the closed joint between the protective lid and the bottom frame. Providing a slidable protective lid can improve the convenience of using the protective cover.

[0044] In some embodiments, the protective cover also includes a first sensing component for sensing the protective cover, and a second sensing component for sensing the support base, and the first sensing component and the second sensing component are both communicatively connected to the laser engraving machine; performing closure detection on the protective cover and the support base includes: respectively obtaining the sensing results of the first sensing component and the second sensing component, performing closure detection on the protective cover according to the sensing results of the first sensing component, and performing closure detection on the support base according to the sensing results of the second sensing component.

[0045] In some embodiments, the protective cover further comprises a support base for supporting the laser engraving machine. By providing the support base, on the one hand, the laser engraving machine can be supported, and on the other hand, smoke generated during the operation of the laser engraving machine can be prevented from leaking.

[0046] In some embodiments, the laser engraving machine is further configured to perform a closure test on the protective cover at a second position, where the second position includes the abutment between the support base and the laser engraving machine. Since a gap exists between the abutment between the support base and the laser engraving machine, smoke generated during operation of the laser engraving machine may leak through the gap. By performing a closure test on the protective cover at the second position, smoke leakage can be effectively prevented.

[0047] It should be noted that the specific structure of the protective cover is described in detail in subsequent embodiments, and in order to avoid repetition, it will not be repeated here.

[0048] Step 102: Determine whether the protective cover completely closes the laser engraving machine in the first position according to the result of the closing detection.

[0049] In some embodiments, when the protective cover includes the aforementioned protective cover and bottom frame, this step can be implemented as follows: determine whether there is a gap at the closed joint between the protective cover and the bottom frame based on the result of the closure detection.

[0050] In some embodiments, when the protective cover includes the aforementioned support base, the aforementioned steps also include a closure test of the protective cover in the second position. Therefore, this embodiment also determines whether the protective cover completely encloses the laser engraving machine in the second position based on the results of the closure test. Specifically, based on the results of the closure test, it is determined whether there is a gap at the abutment between the support base and the laser engraving machine.

[0051] In some embodiments, when the protective cover includes the first sensing component and the second sensing component mentioned above, this step can be implemented in the following manner: determine whether there is a gap at the closed joint between the protective cover and the bottom frame based on whether the first sensing component senses the protective cover, and determine whether there is a gap at the joint between the support base and the laser engraving machine based on whether the second sensing component senses the support base.

[0052] Step 103: When it is determined that the protective cover does not completely enclose the laser engraving machine in the first position, a reminder message is sent.

[0053] In some embodiments, the reminder information may be a voice reminder, a text reminder, etc. This embodiment does not specifically limit the type of the reminder message.

[0054] In some embodiments, taking the protective cover including the aforementioned first sensing component and second sensing component as an example, when the first sensing component does not sense the protective cover, and / or when the second sensing component does not sense the supporting base, it is determined that the protective cover does not completely enclose the laser engraving machine.

[0055] Compared with the related art, the embodiments of the present application have at least the following advantages: by detecting the closure of the protective cover, it is easy to know whether the protective cover completely encloses the laser engraving machine, and when it is determined that the protective cover does not completely enclose the laser engraving machine, a reminder message is sent, so that the user can adjust the protective cover even if necessary, avoiding the situation where "there are gaps at the bottom of the protective cover, which on the one hand will cause the smoke generated when the laser engraving machine is working to be discharged from the gaps, and on the other hand, external impurities will easily enter the protective cover through the gaps, resulting in the safety protection performance of the protective cover being affected". It can ensure the safety protection of the laser engraving machine and improve the user experience.

[0056] For ease of understanding, the following describes in detail how the protective cover of this embodiment achieves safety protection for the laser engraving machine, in conjunction with the protective cover structures shown in FIG. 2 to FIG. 9 :

[0057] 2 , 3 , and 4 , this embodiment provides a protective cover 100, comprising a bracket assembly 10, a first side panel 21, a second side panel 22, a first protective cover 31, and a second protective cover 32. The bracket assembly 10 comprises a base frame 11, a first bracket 12, and a second bracket 13, wherein the first bracket 12 and the second bracket 13 are respectively disposed on opposite sides of the base frame 11. The first side panel 21 is mounted on one side of the first bracket 12 and the base frame 11, and the second side panel 22 is mounted on one side of the second bracket 13 and the base frame 11. The first protective cover 31 and the second protective cover 32 are mounted between the first bracket 12 and the second bracket 13. The first bracket 12 and the second bracket 13 are provided with a first slide groove 14 opposite to each other, and the first protective cover 31 can slide along the first slide groove 14 until it partially overlaps with the second protective cover 32. It is understood that the first position mentioned above is the closed joint between the first protective cover 31 and the base frame 11.

[0058] As shown in Figures 2 and 3, an embodiment of the present application further provides a laser engraving machine 200, comprising a machine base 202, a laser engraving head 201, a control panel 203, and the protective cover 100 described in the above embodiment. The laser engraving head 201 is movably mounted on the machine base 202, the protective cover 100 is mounted on the machine base 202, the laser engraving head 201 is accommodated in the protective cover 100, and the control panel 203 is mounted on the outside of the machine base 202. The mainboard of the laser engraving machine 200 can be disposed within the control panel 203.

[0059] In some embodiments, the first protective cover 31 and the second protective cover 32 may also be made entirely or partially of transparent material, so that the user can observe the working conditions of the internal equipment from the outside without having to frequently open and close the protective cover 100.

[0060] In this application, the outer dimensions of the protective cover 100 are controlled within the size range of the laser engraving machine 200. The protective cover 100 can be assembled as a whole on the working platform of the laser engraving machine 200. The protective cover 100 can be opened and closed by pushing and pulling the first protective cover 31 so that the first protective cover 31 slides along the bracket, thereby avoiding the protective cover from folding and occupying additional space. In addition, the first protective cover 31 and the second protective cover 32 can be partially stacked, further reducing the space occupied by the first protective cover 31 during the sliding process, effectively improving space utilization, and meeting the complex and changeable actual usage scenarios of the production space.

[0061] Referring to Figures 4, 6, and 7, a sensing element 41 is located on one side of the first protective cover 31 near the bottom frame 11. The bottom frame 11 is provided with a sensor 42 corresponding to the sensing element 41. The sensor 42 is used to detect the position of the sensing element 41 to determine the open or closed state of the protective cover 100. It is understood that the sensing element 41 and the sensor 42 are the aforementioned first sensing component.

[0062] Specifically, the first protective cover 31 further includes a push-pull handle 315, which is disposed on the side of the first portion 311 away from the second portion 312. The sensing element 41 is installed on the side of the push-pull handle 315 facing the bottom frame 11. In one embodiment, the sensing element 41 is a magnetic element, and the sensor 42 is a magnetic sensor 42, which determines the opening and closing state of the protective cover 100 by sensing changes in the magnetic field. In other embodiments, the sensor 42 can also be a photoelectric sensor 42, etc., and the sensing element 41 is a thin sheet structure that can block the photoelectric signal on the sensor 42, as long as the detection requirements are met, and the present application is not limited thereto.

[0063] Referring to Figures 2, 3, and 9, the protective cover 100 also includes a support base 204. The support base 204 is located at the bottom of the laser engraver 200 and can be considered a part of the laser engraver 200. It is used to support the laser engraver 200 and can adjust the height of the laser engraver 200 to suit different working requirements. It should be understood that the second position mentioned above is the point where the laser engraver 200 abuts the support base 204.

[0064] Specifically, the support base 204 includes an upper support member 2041, a lower support member 2042, and a seal 2044. The upper support member 2041 and the lower support member 2042 are stacked, and the stacking quantity can be customized according to design requirements. The base 202 of the laser engraving machine 200 is placed on the upper support member 2041, and the seal 2044 is located at the bottom of the lower support member 2042. The seal 2044 is used to seal the bottom gap to prevent external impurities from entering the laser engraving machine 200.

[0065] In one embodiment, the support base 204 is roughly rectangular. The support base 204 also includes corner connectors 2043. A plurality of upper support rods are spliced ​​together to form a rectangular upper support member 2041. The corner connectors 2043 are fixedly connected between two adjacent upper support rods to shape the upper support member 2041. A plurality of lower support rods are spliced ​​together to form a rectangular lower support member 2042. The corner connectors 2043 are also fixedly connected between two adjacent lower support rods to achieve the shaping of the lower support member 2042. The upper support member 2041 and the lower support member 2042 can also be stably stacked by the upper and lower alignment and connection between the corner connectors 2043. The support base 204 has a simple structure and is easy to disassemble, assemble, and adjust.

[0066] A second sensing component (not shown) is provided on the support base 204 . The structure of the second sensing component may be the same as that of the first sensing component, that is, the second sensing component includes a magnetic element and a magnetic sensor.

[0067] The user performs a key operation on the control panel 203, such as pressing the "Preview" key. The main control module of the laser engraving machine responds to the user's key operation and obtains sensing information from the first sensing component and the second sensing component. For example, the first sensing component and the second sensing component are both a combination of a Hall effect magnetic sensor and a magnetic element. Since the level signal at the output end of the Hall effect magnetic sensor is low when no magnetic element is sensed, and the level signal at the output end is high when the magnetic element is sensed, the magnetic element is disposed on the first protective cover 31 and the Hall effect magnetic sensor is disposed on the bottom frame 11. When the first protective cover 31 is in contact with the bottom frame 11, the Hall effect magnetic sensor senses the magnetic element, and the level signal at the output end of the Hall effect magnetic sensor is high. When the first protective cover 31 is not in contact with the bottom frame 11, the Hall effect magnetic sensor does not sense the magnetic element, and the level signal at the output end of the Hall effect magnetic sensor is low, thereby realizing detection of whether the protective cover is completely closed. Similarly, the second sensing component is disposed on the support base 204 to realize detection of whether there is a gap between the support base 204 and the laser engraving machine 200.

[0068] Please further refer to Figure 5. In one embodiment, the first bracket 12 and the second bracket 13 are further provided with a second slide groove 15 opposite to each other. The first slide groove 14 can be arranged vertically parallel to the second slide groove 15, and the second protective cover 32 can slide along the second slide groove 15 until it partially overlaps with the first protective cover 31, thereby allowing the second protective cover 32 to slide relative to the first bracket 12 and the second bracket 13. The second protective cover 32 can slide synchronously with the first protective cover 31 or separately from the first protective cover 31, allowing the protective cover 100 to be opened from different directions, which helps to improve the versatility and ease of use of the protective cover 100.

[0069] Furthermore, referring to Figures 5 and 6 , in an alternative embodiment, the first bracket 12 and the second bracket 13 are generally U-shaped and are invertedly mounted on opposite sides of the base frame 11. The first bracket 12 can be formed by joining two generally L-shaped first support members 120 front to back. Each first support member 120 includes a first straight portion 121 and a first curved portion 122. The first straight portion 121 is arranged parallel to the base frame 11, and the first curved portion 122 is connected between the base frame 11 and the first straight portion 121. The first straight portions 121 of the two first support members 120 are joined front to back. The second bracket 13 can also be formed by joining two generally L-shaped second support members 130 front to back. Each second support member 130 includes a second straight portion 131 and a second curved portion 132. The second straight portion 131 is arranged parallel to the base frame 11 and at the same height as the first straight portion 121. The second curved portion 132 is connected between the base frame 11 and the second straight portion 131. The second straight portions 131 of the two second support members 130 are connected front to back. The first straight portion 121 and the first curved portion 122 are both provided with a first chute 14 and a second chute 15 on their inner sides. The second straight portion 131 and the second curved portion 132 are also provided with a first chute 14 and a second chute 15 on their inner sides.

[0070] It is understood that in other embodiments, the two first support members 120 may also be integrally formed, forming the first bracket 12 into an integral U-shaped structure, with the two first curved portions 122 respectively connected to the front and rear sides of the first straight portion 121. The two second support members 130 may also be integrally formed, forming the second bracket 13 into an integral U-shaped structure, with the two second curved portions 132 respectively connected to the front and rear sides of the second straight portion 131.

[0071] Furthermore, the first protective cover 31 is partially bendably disposed between the first curved portion 122 and the second curved portion 132 on one side of the bracket assembly 10, and the first protective cover 31 can slide along the first curved portion 122 and the second curved portion 132 on one side of the bracket assembly 10 to the first straight portion 121 and the second straight portion 131. The second protective cover 32 is partially bendably disposed between the first curved portion 122 and the second curved portion 132 on the other side of the bracket assembly 10, and the second protective cover 32 can slide along the first curved portion 122 and the second curved portion 132 on the other side of the bracket assembly 10 to the first straight portion 121 and the second straight portion 131. Specifically, the first protective cover 31 is partially made of a flexible material to adapt to the bending and deformation structure of the first chute 14, and the second protective cover 32 can also be partially made of a flexible material to adapt to the bending and deformation structure of the second chute 15. In this way, the first protective cover 31 and the second protective cover 32 can adapt to the shape of the bracket during the sliding process, increasing the movement stroke of the first protective cover 31 and the second protective cover 32, and making the opening of the protective cover 100 larger when opened, which is convenient for user operation and improves the user experience.

[0072] Referring to Figures 4 and 6, in an optional embodiment, the first protective cover 31 includes a first portion 311, a second portion 312, a connector 313, and an edge seal 314. The first portion 311 is a flexible structure and can be flexibly installed between the first curved portion 122 and the second curved portion 132. Both sides of the first portion 311 are respectively accommodated in the first chute 14. The second portion 312 is connected to the side of the first portion 311 facing the second protective cover 32 and is installed between the first straight portion 121 and the second straight portion 131. Both sides of the second portion 312 are also respectively accommodated in the first chute 14. The second portion 312 can be a rigid structure or a flexible structure. The connector 313 is provided at the connection between the first portion 311 and the second portion 312 to fixedly connect the first portion 311 and the second portion 312. The edge seal 314 is provided on the side of the second portion 312 away from the first portion 311 to protect the second portion 312.

[0073] Furthermore, a sliding member may be provided on the side of the first portion 311 and / or the second portion 312, and the sliding member is received in the first sliding groove 14 to reduce frictional resistance and improve sliding smoothness. In one embodiment, the sliding member may be a sliding belt fixed to the side of the first portion 311 and / or the second portion 312 by adhesive bonding.

[0074] When the second protective cover 32 can slide relative to the bracket assembly 10, the structure of the second protective cover 32 is roughly the same as that of the first protective cover 31, and the matching structure between the second protective cover 32 and the second slide groove 15 is also the same as the matching structure between the first protective cover 31 and the first slide groove 14, which will not be repeated here.

[0075] Please refer to Figure 10, which is a flow chart of a control method for a laser engraving machine provided in an embodiment of the present application. This embodiment is a further improvement on the previous embodiment. The main improvement is that in this embodiment, the first sensing component and the second sensing component are both connected to the safety detection bus of the laser engraving machine. If one of the first sensing component and the second sensing component does not sense the required structure, the power supply of the laser engraving machine is controlled to be disconnected. In this way, the safety of the laser engraving machine during operation can be further improved.

[0076] As shown in FIG10 , the embodiment of the present application includes the following steps:

[0077] Step 201: In response to the protection detection information, respectively obtain the sensing results of the first sensing component and the second sensing component, perform a closure detection on the protective cover according to the sensing result of the first sensing component, and perform a closure detection on the support base according to the sensing result of the second sensing component.

[0078] Step 202: Determine whether there is a gap between the closed joint of the protective cover and the bottom frame based on whether the first sensing component senses the protective cover, and determine whether there is a gap between the joint of the support base and the laser engraving machine based on whether the second sensing component senses the support base.

[0079] Step 203: When there is a gap at the joint between the protective cover and the bottom frame, and / or when there is a gap between the support base and the laser engraving machine, a reminder message is sent.

[0080] Steps 201 to 203 are similar to steps 101 to 103 in the aforementioned embodiment, and will not be described again here to avoid repetition.

[0081] Step 204: During the operation of the laser engraving machine, the level state of the safety detection bus is detected, wherein, when the first sensing component does not sense the protective cover and / or the second sensing component does not sense the support base, the level state is low; when the first sensing component senses the protective cover and the second sensing component senses the support base, the level state is high.

[0082] In some embodiments, the first sensing component and the second sensing component are both a combination of the Hall magnetic sensor and the magnetic element mentioned in the aforementioned embodiments. The Hall magnetic sensor is connected to the safety detection bus. Since the level signal at the output end of the Hall magnetic sensor is low when the magnetic element is not sensed, the level state of the safety detection bus is also low, thereby realizing the determination of whether the first sensing component senses the protective cover and whether the second sensing component senses the support base based on the level state of the safety detection bus.

[0083] In some embodiments, the protective cover also includes a first indicator light corresponding to the first sensing component, and a second indicator light corresponding to the second sensing component; when the sensing result of the first sensing component is that the protective cover is not detected, the main control module of the laser engraving machine controls the first indicator light to display a preset color; when the sensing result of the second sensing component is that the supporting base is not detected, the main control module of the laser engraving machine controls the second indicator light to display the preset color.

[0084] For example, if the first sensing component detects that the protective cover is not detected, the first indicator light will turn red; if the first sensing component detects that the protective cover is detected, the first indicator light will turn blue. If the second sensing component detects that the support base is not detected, the second indicator light will turn red; if the second sensing component detects that the support base is not detected, the second indicator light will turn blue. This method allows users to quickly confirm that there is no closed structure and make timely adjustments, further improving the user experience.

[0085] Step 205: When it is detected that the level state of the safety detection bus is low, the power supply of the laser engraving machine is controlled to be disconnected.

[0086] In some embodiments, after controlling the power of the laser engraving machine to be turned off, the control method further includes: re-detecting the level state of the safety detection bus; and controlling the power of the laser engraving machine to be turned back on when detecting that the level state of the safety detection bus has changed to a high level.

[0087] Compared with the related art, the embodiments of the present application have at least the following advantages: by detecting the closure of the protective cover, it is easy to know whether the protective cover completely encloses the laser engraving machine, and when it is determined that the protective cover does not completely enclose the laser engraving machine, a reminder message is sent, so that the user can adjust the protective cover even if necessary, avoiding the situation where "there are gaps at the bottom of the protective cover, which on the one hand will cause the smoke generated when the laser engraving machine is working to be discharged from the gaps, and on the other hand, external impurities will easily enter the protective cover through the gaps, resulting in the safety protection performance of the protective cover being affected". It can ensure the safety protection of the laser engraving machine and improve the user experience.

[0088] Please refer to Figure 11, which is a flow chart of the control method for a laser engraving machine provided in an embodiment of the present application. This embodiment is a further improvement on the previous embodiment. The main improvements are: in this embodiment, the protective cover also includes a lighting assembly, which is powered by the power supply of the laser engraving machine; the control method also includes determining the lighting operating mode of the lighting assembly in response to the lighting mode selection information, and controlling the lighting assembly to emit light according to the lighting operating mode. In this way, energy consumption can be reduced without affecting the operation of the laser engraving machine, improving the user experience; in addition, the lighting function within the protective cover can be realized without an external power supply, further improving the user experience.

[0089] As shown in FIG11 , the embodiment of the present application includes the following steps:

[0090] Execute steps 101 to 103.

[0091] Step 301: Determine a lighting operating mode of a lighting assembly in response to lighting mode selection information.

[0092] In some embodiments, a lighting switch is provided on the protective cover or the laser engraving machine, and a user can select a lighting mode of the lighting assembly by operating the lighting switch. When the user operates the lighting switch, the lighting switch transmits lighting mode selection information, and the main control module of the laser engraving machine determines the lighting operating mode of the lighting assembly in response to the lighting mode selection information.

[0093] Step 302: Control the lighting component to emit light according to the lighting working mode, wherein the lighting working mode includes at least a first lighting mode and a second lighting mode. When the lighting component is in the first lighting mode, the lighting component emits light when the laser engraving machine is powered on; when the lighting component is in the second lighting mode, the lighting component emits light when the laser module of the laser engraving machine is working.

[0094] Specifically, when the lighting assembly is in the first lighting mode, the lighting assembly turns on the light when the laser engraving machine is powered on and turns off when the laser engraving machine is powered off. When the lighting assembly is in the second lighting mode, the lighting assembly does not turn on the light when the laser engraving machine is powered on, but turns on the light when the laser module is operating and turns off when the laser module stops operating. This approach can reduce energy consumption.

[0095] In some embodiments, the protective cover further includes a visual detection component to enable remote monitoring and control of the laser engraving machine.

[0096] Compared with the related art, the embodiments of the present application have at least the following advantages: by detecting the closure of the protective cover, it is easy to know whether the protective cover completely encloses the laser engraving machine, and when it is determined that the protective cover does not completely enclose the laser engraving machine, a reminder message is sent, so that the user can adjust the protective cover even if necessary, avoiding the situation where "there are gaps at the bottom of the protective cover, which on the one hand will cause the smoke generated when the laser engraving machine is working to be discharged from the gaps, and on the other hand, external impurities will easily enter the protective cover through the gaps, resulting in the safety protection performance of the protective cover being affected".

[0100] In an optional embodiment, an adapter 65 is further provided on the lighting circuit board 61.

[0101] In one embodiment, the laser engraving machine 200 mainboard can control the lighting element 62 using pulse signals of varying frequencies to implement a dimming function. The lighting element 62 can be turned on and off manually by controlling the lighting switch 63, while the laser engraving machine 200 can automatically control the brightness of the lighting element 62, providing a more user-friendly experience.

[0102] In another embodiment, the sensor 42 can also be set at a position corresponding to the sensing element 41 on the lighting circuit board 61. The sensor 42 is electrically connected to the lighting circuit board 61 and connected to the main board of the laser engraving machine 200 through the lighting circuit board 61, so that the opening and closing signals of the protective cover 100 can be transmitted to the main board of the laser engraving machine 200 in real time.

[0103] Furthermore, an indicator light 43 may be provided on the lighting circuit board 61. The sensor 42 is electrically connected to the indicator light 43. The indicator light 43 may illuminate when the protective cover 100 is open and extinguish when the protective cover 100 is closed, or may be displayed red when the protective cover 100 is open and green when the protective cover 100 is closed, thereby providing a user with a reminder. An opening corresponding to the indicator light 43 is provided on the lighting mounting base 111. The indicator light 43 may be partially exposed through the opening, allowing the user to observe the on / off state or color of the indicator light 43 from outside the protective cover 100.

[0104] 4, 5, and 8, the protective cover 100 further includes a visual inspection assembly 50, which includes a mounting bracket 51, a camera 53, and a control module 52.

[0105] Specifically, the mounting frame 51 is connected between the first straight portion 121 and the second straight portion 131, and is roughly located in the middle area of ​​the first bracket 12 and the second bracket 13, so that the camera 53 is located at the top position of the protective cover 100, and can shoot the working platform of the engraving machine from a bird's-eye view, with a large viewing angle and small error. A mounting slot 511 is also provided in the middle position of the mounting frame 51, and the control module 52 is arranged in the mounting slot 511. The camera 53 is connected to the side of the control module 52 facing away from the mounting frame 51 and protrudes from the mounting slot 511. The control module 52 is used to receive and process image information or video information captured by the camera 53.

[0106] Please refer to Figure 12, which is a flow chart of the control method for a laser engraving machine provided in an embodiment of the present application. This embodiment is a further improvement on the previous embodiment, with the main improvements being: in this embodiment, the protective cover also includes an exhaust assembly, and the control method further includes determining the exhaust operating mode of the lighting assembly in response to the exhaust mode selection information, and controlling the operation of the exhaust assembly according to the exhaust operating mode. In this way, energy consumption can be reduced without affecting the operation of the laser engraving machine, improving the user experience; in addition, the exhaust function within the protective cover can be achieved without an external power supply, further improving the user experience.

[0107] As shown in FIG12 , the embodiment of the present application includes the following steps:

[0108] Execute steps 101 to 103.

[0109] Step 401: In response to the exhaust mode selection information, determine the exhaust operation mode of the exhaust component.

[0110] In some embodiments, a vent switch is provided on the protective cover or the laser engraving machine, and a user can select an exhaust mode for the exhaust assembly by operating the vent switch. When the user operates the vent switch, the vent switch transmits exhaust mode selection information, and the main control module of the laser engraving machine responds to the exhaust mode selection information and determines the exhaust operating mode of the exhaust assembly.

[0111] Step 402: Control the operation of the exhaust component according to the exhaust working mode, wherein the exhaust working mode includes at least a first exhaust mode and a second exhaust mode. When the exhaust component is in the first exhaust mode, the exhaust component operates when the laser engraving machine is powered on; when the exhaust component is in the second exhaust mode, the exhaust component operates when the laser module of the laser engraving machine is working.

[0112] Specifically, when the exhaust assembly is in the first exhaust mode, it opens when the laser engraving machine is powered on and closes when the laser engraving machine is powered off. When the exhaust assembly is in the second exhaust mode, the exhaust assembly remains closed when the laser engraving machine is powered on, opens when the laser module is operating, and closes when the laser module stops operating. This approach can further reduce energy consumption.

[0113] Compared with the related art, the embodiments of the present application have at least the following advantages: by detecting the closure of the protective cover, it is easy to know whether the protective cover completely encloses the laser engraving machine, and when it is determined that the protective cover does not completely enclose the laser engraving machine, a reminder message is sent, so that the user can adjust the protective cover even if necessary, avoiding the situation where "there are gaps at the bottom of the protective cover, which on the one hand will cause the smoke generated when the laser engraving machine is working to be discharged from the gaps, and on the other hand, external impurities will easily enter the protective cover through the gaps, resulting in the safety protection performance of the protective cover being affected". It can ensure the safety protection of the laser engraving machine and improve the user experience.

[0114] For ease of understanding, the control method of the laser engraving machine of this embodiment is specifically described below in conjunction with the specific structure of the exhaust:

[0115] As shown in Figures 4, 6, and 7, the protective cover 100 further includes an exhaust assembly 70, which is mounted on the second side panel 22 and electrically connected to the lighting circuit board 61. Thus, the exhaust assembly 70 can also be connected to the mainboard of the laser engraving machine 200 via the lighting circuit board 61, enabling the laser engraving machine 200 to control the exhaust assembly 70 in the protective cover 100.

[0116] Furthermore, the exhaust assembly 70 includes a fan 71, a connector 72, and an exhaust switch 73. The second side panel 22 defines a vent 222, and the fan 71 is mounted at the vent 222. The connector 72 and exhaust switch 73 are located on the side of the lighting circuit board 61 near the second bracket 13. The fan 71 is electrically connected to the connector 72, allowing the fan 71 to be powered by the lighting circuit board 61. The second side panel 22 defines a second through-slot 221, which partially accommodates the exhaust switch 73. Users can manually turn the exhaust switch 73 on and off from the outside of the second side panel 22 and set different gears on the exhaust switch 73 to adjust the wind speed of the fan 71. Users can also adjust the fan 71's on / off status or air volume from the laser engraving machine 200. The control method for the fan 71 is substantially the same as that for the lighting assembly 60 and will not be further described here. When the fan 71 is activated, it creates a negative pressure at the vent 222, forcing the air within the protective cover 100 to flow toward the vent 222, thereby extracting the air from the protective cover 100. In other embodiments, the fan 71 may also be installed on the first side panel 21 to meet actual needs, and the present application is not limited thereto.

[0117] In an optional embodiment, the exhaust assembly 70 further includes a filter 74, which is disposed between the fan 71 and the vent 222, and covers the vent 222. As the gas flows out of the vent 222, it is first filtered and purified by the filter 74, and then the fan 71 draws the filtered gas to the outside, thereby reducing environmental pollution.
