[0025] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0026] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0027] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0028] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0029] Laser TV is a projection display device that uses laser light source as display light source and cooperates with front projection display technology to form images, is equipped with a dedicated projection screen, and can receive broadcast and television programs or Internet television programs. Figure 1 As shown, the laser TV includes a laser projection device 100 and a projection screen 200. The laser projection device 100 can emit a laser beam to the projection screen 200, and the projection screen 200 reflects the beam to display a picture.

[0030] The projection screen 200 may be an optical screen. Exemplarily, the projection screen may be composed of a support plate and a membrane located on the support plate. The membrane may be an optical membrane mainly composed of a Fresnel lens layer. For example, the membrane may include a diffusion layer, a substrate layer and a Fresnel lens layer stacked in sequence in a direction away from the laser projection device 100 (or, it may also include a substrate layer, a diffusion layer and a Fresnel lens layer stacked in sequence); wherein the substrate layer is a transparent film layer. When displaying an image, a light beam is emitted from the laser projection device 100. When passing through the diffusion layer, the light is dispersed by the diffusion layer and then reflected on the surface of the Fresnel lens layer, so that the user can view the image. Exemplarily, the support plate may be bonded to the membrane by an adhesive layer to fix and flatten the membrane. The adhesive layer may be a double-sided adhesive layer or a glue layer.

[0031] Since the laser projection device emits a light beam through the lens, which is a precision component, a lens protection device is required to protect the projection lens inside the laser projection device from being scratched by external forces or falling into dust. The lens protection device automatically opens when the laser TV is turned on, allowing the light beam emitted by the lens to be projected onto the projection screen, and automatically closes when the laser TV is turned off to protect the lens.

[0032] The lens protection device comprises: a first cover body and a second cover body. Figure 2 As shown, it is a structural schematic diagram of a laser TV provided by the present application, including a first cover body 101 and a second cover body 102, a rectangular shell 20, and the shell 20 includes: a shell wall 201, a side wall 202, and a bottom wall; the projection host is installed in the shell 20.

[0033] In an embodiment of the present application, a laser television control method is provided, such as Figure 3 As shown, the laser TV control method includes the following steps 301 to 304.

[0034] 301. In response to a received power-on command for turning on the laser TV, the first cover is controlled to move away from the light outlet in a direction perpendicular to the shell wall, and the second cover is controlled to rotate relative to the shell to expose the light outlet.

[0035] 302. In response to a received shutdown command for shutting down the laser TV, control the first cover body to approach the light outlet in a direction perpendicular to the shell wall, and control the second cover body to rotate relative to the shell to cover the light outlet.

[0036] 303. During the process of the second cover body rotating relative to the shell to block the light outlet, if the driving current driving the second cover body is greater than or equal to the stall current, the second cover body is controlled to rotate relative to the shell to expose the light outlet again, and the countdown is started and a foreign object prompt message is output.

[0037] Wherein, a foreign object prompt message is output to prompt the user to remove the foreign object that blocks the closing of the second cover.

[0038] 304. If the countdown ends and the driving current is less than the stall current, the second cover is controlled to rotate relative to the housing again to cover the light outlet.

[0039] Optionally, in combination with FIG. 3 , as Figure 4 As shown, before the above step 304, the method further includes the following steps 305 and 306.

[0040] 305. When the second cover rotates relative to the shell to expose the light outlet again, if the driving current is less than the stall current, the second cover is controlled to stop rotating.

[0041] 306. During the countdown process, if the driving current is greater than or equal to the stall current, the countdown will be restarted.

[0042] It can be understood that by controlling the second cover to stop rotating, the second cover may be partially opened or fully opened. If the second cover is partially opened, time can be saved when closing next time, thereby improving closing efficiency.

[0043] It can be understood that the movement order of the first cover body and the second cover body during the power-on and power-off process is not limited in this application. It can be that the first cover body is first driven to move to the corresponding preset position, and then the second cover body is driven to move to the corresponding preset position; it can also be that the second cover body is first driven to move to the corresponding preset position, and then the first cover body is driven to move to the corresponding preset position; it can also be that the first cover body and the second cover body are driven to move at the same time, which is determined according to actual needs. The following is an example of driving the first cover body to move to the corresponding preset position first and then the second cover body to move to the corresponding preset position when the power is turned on; and driving the second cover body to move to the corresponding preset position first and then the first cover body to move to the corresponding preset position when the power is turned off.

[0044] When the system on chip (SOC) of the whole machine (laser TV) receives a power-on command from the user to turn on the laser TV, the SOC of the whole machine sends a power-on command to the microcontroller (MCU) of the driver board. After receiving the command, the driver board MCU controls the motor corresponding to the first cover body to operate so that the first cover body rises to a preset position without blocking the light outlet; after the first cover body rises to the corresponding preset position, the driver board MCU receives a signal from a limit switch that triggers the position, and the driver board MCU controls the motor corresponding to the second cover body to operate so that the second cover body rotates open to expose the entire projection lens. When the whole machine SOC receives a shutdown command from the user instructing to shut down the laser TV, the whole machine SOC sends a shutdown command to the display board MCU. After receiving the shutdown command, the display board MCU sends a shutdown command to the first cover and the second cover of the laser. After receiving the shutdown command, the laser stops emitting light, and the driver board MCU controls the motor corresponding to the second cover to close the second cover; after the second cover is completely closed (such as setting a limit switch at the contact position of the two quarter circles of the second cover, and after the driver board MCU receives the signal sent by the trigger limit switch, it is determined that the second cover is completely closed), the driver board MCU controls the motor corresponding to the first cover to move the first cover to the corresponding preset position (such as setting a limit switch at the preset position, and after the driver board MCU receives the signal sent by the trigger limit switch, it is determined that the first cover has reached the preset position).

[0045] It can be understood that the first cover body and the second cover body are in the same horizontal plane after being fully closed. In this way, it can be ensured that the first cover body and the second cover body completely cover the projection lens while making the appearance of the laser TV smoother and more beautiful.

[0046] It can be understood that during the closing process of the second cover, if a foreign object is stuck in the contact position of the second cover, on the one hand, the projection lens may be dirty or scratched due to the foreign object, affecting the display effect; on the other hand, the foreign object may be a part of the user's body, such as if the user puts his hand at the contact position of the second cover, and continuing to close may cause harm to the user. Therefore, during the closing process of the second cover, the change of the drive current is continuously detected. When the drive current is greater than or equal to the stall current, it is determined that there is a foreign object blocking the closing of the second cover. In this case, the driver board MCU controls the motor of the second cover to reverse, so that the second cover is opened to avoid harm to the user, and enters the countdown and outputs a foreign object prompt message. During the opening process of the second cover, the driving current will gradually decrease. When the driving current is less than or equal to the stall current, the second cover will stop opening (the second cover may be partially opened or fully opened). During the countdown, if the foreign object detection sensor detects a foreign object, the countdown will be restarted. During the entire countdown, if the foreign object detection sensor is not triggered, that is, the driving current is always less than the stall current, the driver board MCU determines that the foreign object has been removed, and re-executes the step of closing the second cover, and repeats this process until the second cover is completely closed. Alternatively, during a shutdown process, if the second cover repeats the closing operation for a number of times equal to a preset threshold number of times, the step of closing the second cover will no longer be executed.

[0047] It can be understood that the foreign object prompt message can be output in the form of a flashing indicator light, a voice, or a display on the screen of the laser TV. In the case where the foreign object prompt message is displayed on the screen to prompt the user, the driver board MCU reports to the whole machine SOC to indicate the abnormal state of the presence of foreign objects, and the whole machine SOC sends to the display board MCU a command to instruct the laser TV to restart and turn on the laser, and pop up a UI interface to display the foreign object prompt message.

[0048] It can be understood that when the second cover starts to close, the closing speed of the second cover is controlled to be higher so as to close the second cover quickly; when the second cover is about to be completely closed, the closing speed of the second cover is controlled to be lower so as to avoid damage to the second cover due to impact caused by excessive speed and generate loud noise.

[0049] For example, in combination Figure 2 When the angle between the two quarter circles of the second cover is greater than or equal to the first preset angle, the stepper motor of the second cover is controlled to move at a first frequency; when the angle between the two quarter circles of the second cover is less than the first preset angle, the stepper motor of the second cover is controlled to move at a second frequency. The first frequency is greater than the second frequency.

[0050] In an embodiment of the present application, the laser TV includes: a shell, in which a projection host is installed; the shell includes a shell wall, the shell wall has a light outlet, and a first cover body and a second cover body are arranged at the light outlet to protect the lens; the laser TV control method includes: in response to a received power-on command for turning on the laser TV, controlling the first cover body to move away from the light outlet in a direction perpendicular to the shell wall, and controlling the second cover body to rotate relative to the shell to expose the light outlet; in response to a received power-off command for turning off the laser TV, controlling the first cover body to move close to the light outlet in a direction perpendicular to the shell wall, and controlling the second cover body to rotate relative to the shell to block the light outlet; in the process of the second cover body rotating relative to the shell to block the light outlet, if the driving current driving the second cover body is greater than or equal to the stall current, the second cover body is controlled to rotate relative to the shell to expose the light outlet again, a countdown is started, and a foreign object prompt message is output to prompt the user to remove the foreign object blocking the closing of the second cover body; if the countdown ends and the driving current is less than the stall current, the second cover body is controlled to rotate relative to the shell again to block the light outlet. In this way, the projection lens is protected from being scratched or contaminated by foreign objects by controlling the first cover and the second cover. At the same time, during the closing process of the second cover, if there is foreign matter causing the motor of the second cover to be blocked, the second cover is reopened to avoid forcibly closing the second cover, which may damage the motor or cause personal injury to the user.

[0051] In some embodiments of the present application, Figure 4 ,like Figure 5 As shown, after the above step 302, the laser TV control method further includes the following step 307.

[0052] 307. If the first cover body does not reach the first position within the first preset time period, a fault prompt message is output to prompt the user that the first cover body is faulty.

[0053] When the first cover body is located at the first position, the first cover body and the second cover body are on the same horizontal plane.

[0054] It is understandable that by setting a limit switch, when a signal sent by the limit switch being triggered is received, it is determined that the first cover body has reached the first position; if no signal sent by the limit switch being triggered is received within a first preset time period, it is determined that the first cover body has a fault.

[0055] It can be understood that the fault prompt message can be output in the form of a flashing indicator light, in the form of a voice, or displayed on the screen of the laser TV. In the case where the fault prompt message is displayed on the screen to prompt the user, the driver board MCU reports to the whole machine SOC an abnormal state indicating the existence of a first cover body fault, and the whole machine SOC sends a command to the display board MCU to instruct the laser TV to restart and turn on the laser, and pop up a fault prompt message on the UI interface.

[0056] It should be noted that the moving distance of the first cover is relatively small, and human hands and other body parts will not be pinched, and no personal injury will be caused during the up and down movement.

[0057] For example, Figure 6 The figure shows an exemplary shutdown process diagram, which includes the following steps 40 to 50. Among them, when the motor (electric motor) 1 rotates forward, the second cover is opened, and when the motor 1 rotates reversely, the second cover is closed; when the motor 2 rotates forward, the first cover rises, and when the motor 2 rotates reversely, the first cover falls; the limit switch 1 is located at the two quarter-circle contact positions of the second cover, and the limit switch 2 is located at the first position.

[0058] 40. The whole machine SOC issues a shutdown command.

[0059] 41. The driver board MCU receives the shutdown command.

[0060] 42. Turn off the laser and the driver board MCU starts to shut down.

[0061] 43. Motor 1 reverses and turns off.

[0062] 44. The driving current is less than the stall current.

[0063] If yes, execute step 45; otherwise, execute step 46.

[0064] 45. Touch limit switch 1.

[0065] If yes, execute step 47; otherwise, execute step 43.

[0066] 46. ​​Motor 1 rotates forward and retreats.

[0067] 47. Motor 1 stops; Motor 2 reverses and decreases.

[0068] 48. Touch limit switch 2.

[0069] If yes, execute step 49; otherwise, execute step 47.

[0070] 49. MCU reports shutdown status.

[0071] 50. The entire SOC is shut down and powered off.

[0072] In the embodiment of the present application, after controlling the first cover body to approach the light outlet in a direction perpendicular to the shell wall, the method further includes: within a first preset time period, if the first cover body does not reach the first position, outputting a fault prompt message for prompting the user that the first cover body is faulty. Outputting the fault prompt message can help the user know the fault of the laser TV in time, and the output fault prompt information can help maintenance personnel locate the location of the fault, which is convenient for maintenance personnel to repair.

[0073] In some embodiments of the present application, Figure 4 ,like Figure 7 As shown, before the above step 304, the method further includes the following steps 308 and 309. The above step 304 can be specifically implemented by the following step 304a.

[0074] 308. During the shutdown detection process, the second cover body repeatedly rotates relative to the housing to block the light outlet.

[0075] 309. If the execution times are equal to the times threshold, the laser TV is powered off and a shutdown abnormality message is output when the TV is powered on next time.

[0076] The shutdown abnormality message is used to remind the user that the second cover failed to close due to obstruction by foreign matter during the last shutdown.

[0077] 304a, if the countdown ends and the driving current is less than the stall current and the number of executions is less than the number threshold, the second cover is controlled to rotate relative to the housing again to cover the light outlet.

[0078] It can be understood that if the number threshold is three times, and after repeated execution twice, there is still foreign matter blocking the second cover and causing the machine to be unable to shut down normally, after the abnormal prompt message is output for the third time, the whole machine SOC will cut off the power to the display board and the driver board when the driver board MCU reports the abnormal state of the presence of foreign matter for the third time. After the next startup, a prompt box will pop up to remind the user that the last shutdown process was caused by a foreign matter blocking the rotating structure for a long time, resulting in a timeout shutdown. Please do not place other objects on the second cover or put your hands into the opening and closing parts.

[0079] In the embodiment of the present application, before controlling the second cover body to rotate relative to the housing again to block the light outlet, the method further includes: detecting the number of times the second cover body repeatedly rotates relative to the housing to block the light outlet during the shutdown process; if the number of executions is equal to the number threshold, then controlling the laser TV to power off, and outputting a shutdown abnormality message when the TV is turned on next time, the shutdown abnormality message is used to prompt the user that the second cover body failed to close due to foreign matter blocking the TV last time the TV was turned off; controlling the second cover body to rotate relative to the housing again to block the light outlet includes: if the number of executions is less than the number threshold, then controlling the second cover body to rotate relative to the housing again to block the light outlet. In this way, in the case where there is foreign matter blocking the closing part of the second cover body for a long time, resulting in the inability to shut down normally, after multiple attempts, the second cover body is stopped from closing, the laser TV is controlled to time out and shut down, and the user is prompted when the TV is turned on next time, so that the user knows that foreign matter cannot be placed at the second cover body.

[0080] In some embodiments of the present application, Figure 4 ,like Figure 8As shown, after the above step 301, the laser TV control method further includes the following steps 310 to 311.

[0081] 310. When the first cover moves away from the light outlet in a direction perpendicular to the shell wall, if the first cover does not reach the second position within a second preset time, output fault prompt information for prompting a user that the first cover is faulty.

[0082] 311. During the process of the second cover rotating relative to the shell to expose the light outlet, if the second cover is not opened to the first preset angle within a third preset time, a fault prompt message is output to prompt a user that the second cover is faulty.

[0083] It can be understood that whether the first cover body reaches the second position and whether the second cover body is opened to the first preset angle can be determined by setting a limit switch. Specifically, within the second preset time length when the driver board MCU starts to drive the movement of the first cover body, if a signal is received from the limit switch at the second position being triggered, the first cover body reaches the second position; within the second preset time length, if a signal is not received from the limit switch at the second position being triggered, it is determined that the first cover body is faulty. Similarly, a limit switch is set at the position corresponding to the first preset angle, and within the third preset time length when the driver board MCU starts to drive the movement of the second cover body, if a signal is received from the limit switch at the position corresponding to the first preset angle being triggered, the first cover body reaches the second position; within the third preset time length, if a signal is not received from the limit switch at the position corresponding to the first preset angle being triggered, it is determined that the second cover body is faulty.

[0084] It can be understood that if the first cover and / or the second cover of the laser TV fails to open, the laser TV cannot be turned on normally. Therefore, the opening failure message in this case can be output in the form of a flashing indicator light or a preset alarm tone.

[0085] In the embodiment of the present application, after controlling the first cover body to move away from the light outlet in a direction perpendicular to the shell wall, and controlling the second cover body to rotate relative to the shell to expose the light outlet, the method further includes: in the process of the first cover body moving away from the light outlet in a direction perpendicular to the shell wall, if the first cover body does not reach the second position within the second preset time length, then outputting a fault prompt information for prompting the user of the first cover body failure; in the process of the second cover body rotating relative to the shell to expose the light outlet, if the second cover body does not open to the first preset angle within the third preset time length, then outputting a fault prompt information for prompting the user of the second cover body failure. In this way, during the startup process, ensure that the first cover body and the second cover body are fully opened before starting the laser TV, so as to avoid the first cover body and the second cover body not being fully opened to start the laser TV, and the laser being blocked by the first cover body and / or the second cover body after emitting light, resulting in damage to the laser or damage to the first cover body and / or the second cover body, etc., and the output fault prompt message can also facilitate maintenance personnel to quickly locate the problem.

[0086] In some embodiments of the present application, Figure 4 ,like Fig. 9 As shown, after the above step 311, the method further includes the following steps 312 and 313.

[0087] 312. When the opening angle of the second cover is greater than or equal to the second preset angle and the first cover reaches the second position, output a prompt message for prompting the user to manually open the second cover to the first preset angle.

[0088] Wherein, the first preset angle is greater than the second preset angle;

[0089] 313. Control the laser light of laser TV.

[0090] It can be understood that the motor that controls the opening of the second cover is a stepper motor, and the opening and closing angle is determined according to the number of steps of the stepper motor; when the second cover is opened to a certain angle but not fully opened, one will affect the light emission from the light outlet, and the other will not affect the light emission from the light outlet although it is not fully opened. For example, if the first preset angle is 180 degrees and the second preset angle is 120 degrees, that is, when the opening and closing angle of the second cover is greater than or equal to 120 degrees and less than 180 degrees, when the laser emits light, the light outlet can emit light normally. In this case, the second cover fault can be output while prompting the user to open the second cover to 180 degrees to use the laser TV normally.

[0091] For example, Fig.10The figure shows an exemplary shutdown process diagram, including the following steps 11 to 23. Among them, when the motor (electric motor) 1 rotates forward, the second cover is opened, and when the motor 1 rotates reversely, the second cover is closed; when the motor 2 rotates forward, the first cover rises, and when the motor 2 rotates reversely, the first cover falls; the limit switch 1 is located at the two quarter circle contact positions of the second cover, and the limit switch 3 is located at the second position, and the timeout period is 1.5 seconds.

[0092] 11. The whole machine SOC sends a power-on command to the driver board MCU.

[0093] 12. The driver board MCU receives the power-on command.

[0094] 13. Motor 2 rotates forward and rises.

[0095] 14. Touch limit switch 3.

[0096] If yes, go to step 15; otherwise, go to step 16.

[0097] 15. Motor 2 stops; Motor 1 turns on forward rotation.

[0098] 16. Timeout 1.5s.

[0099] If yes, go to step 17; otherwise, go to step 13.

[0100] 17. Output fault prompt message.

[0101] After step 17, go to step 23.

[0102] 18. Touch limit switch 1.

[0103] If yes, go to step 19; otherwise, go to step 21.

[0104] 19. After the startup is completed, report to the display board MCU to light up the laser.

[0105] After step 19, go to step 23.

[0106] 21. The opening angle is less than 120 degrees.

[0107] If yes, go to step 17; otherwise, go to step 22.

[0108] 22. The reporting display panel lights up the laser and prompts the user to open the light outlet.

[0109] 23. Report the SOC power-on status of the whole machine.

[0110] For example, Fig.11The figure shows a structural control diagram of a lens protection device. The whole machine SOC is used to send instructions to the display board MCU, receive the status reported by the display board MCU, and control the indicator light to flash according to the reported status; the display board MCU is used to receive the instructions sent by the whole machine SOC, and forward the instructions to the driver board MCU. The driver board MCU drives the motor 1 to rotate forward or reverse through the motor driver chip 1 to open or close the second cover body, and the driver board MCU drives the motor 2 to rotate forward or reverse through the motor driver chip 2 to open or close the first cover body. Among them, the limit switch 1 is used to feedback to the driver board MCU whether the second cover body is opened to a preset degree or completely closed; the limit switch 2 is used to feedback to the driver board MCU whether the first position is reached; the limit switch 3 is used to feedback to the driver board MCU whether the second position is reached; the current limiting switch is used to feedback to the driver board MCU whether the driving current is greater than or equal to the stall current.

[0111] In the embodiment of the present application, during the process of the second cover rotating relative to the housing to expose the light outlet, if the second cover is not opened to the first preset angle within the third preset time, the method further includes: when the angle of the second cover opening is greater than or equal to the second preset angle and the first cover reaches the second position, outputting a prompt message for prompting the user to manually open the second cover to the first preset angle, the first preset angle being greater than the second preset angle; and controlling the laser of the laser TV to emit light. In this way, when the second cover is not fully opened but the light outlet can emit light normally, the laser is controlled to emit light, prompting the user to manually open the second cover, so that the user can use the laser TV normally.

[0112] In some embodiments of the present application, Figure 4 ,like Fig.12 As shown, before the above step 301, the method further includes the following steps 314 and 315. The above step 301 can be specifically implemented by the following step 301a.

[0113] 314. Check whether the target function is enabled.

[0114] Among them, the target function is used to indicate whether to allow synchronous control of the movement of the first cover body and the second cover body to expose the light outlet or block the light outlet when the laser TV is turned on or off.

[0115] 315. When the target function is turned off, keep the first cover and the second cover in an open state.

[0116] Wherein, the light outlet is in an exposed state in the open state.

[0117] 301a. When the target function is turned on, in response to a received shutdown command to shut down the laser TV, the first cover is controlled to move away from the light outlet in a direction perpendicular to the shell wall, and the second cover is controlled to rotate relative to the shell to expose the light outlet.

[0118] It can be understood that the user is given the authority to decide whether the first cover and the second cover are opened and closed synchronously with the power on and off action, and the user can choose to turn on or off the target function according to the user's usage habits. If the user chooses to turn on the target function, the first cover and the second cover are opened or closed synchronously during the power on and off process; if the user chooses to turn off the target function, the first cover and the second cover are in a normally open state during the power on and off process.

[0119] In an embodiment of the present application, in response to a received power-on command for turning on the laser TV, before controlling the first cover body to move away from the light outlet in a direction perpendicular to the shell wall, and controlling the second cover body to rotate relative to the shell to expose the light outlet, the method further includes: detecting whether a target function is turned on, the target function is used to indicate whether synchronous control of the first cover body and the second cover body to move to expose the light outlet or block the light outlet when the laser TV is turned on or off; when the target function is turned off, keeping the first cover body and the second cover body in an open state, and the light outlet is exposed in the open state; in response to a received power-off command for turning off the laser TV, controlling the first cover body to move away from the light outlet in a direction perpendicular to the shell wall, and controlling the second cover body to rotate relative to the shell to expose the light outlet, including: when the target function is turned on, in response to a received power-off command for turning off the laser TV, controlling the first cover body to move away from the light outlet in a direction perpendicular to the shell wall, and controlling the second cover body to rotate relative to the shell to expose the light outlet. In this way, the user authority is enabled, and the user can flexibly choose to turn on or off the target function. For example, users who use the laser TV frequently can turn off the target function to avoid frequent opening and closing of the first cover and the second cover; users who use the laser TV less frequently can turn on the target function to prevent the projection lens from being exposed to the outside for a long time and being damaged by foreign objects or dust.

[0125] In some embodiments of the present application, the countdown and output module is also used to, after controlling the first cover body to move away from the light outlet in a direction perpendicular to the shell wall and controlling the second cover body to rotate relative to the shell to expose the light outlet, output fault prompt information for prompting a user of a first cover body failure if the first cover body does not reach the second position within a second preset time period during the process of the first cover body moving away from the light outlet in a direction perpendicular to the shell wall; and output fault prompt information for prompting a user of a second cover body failure if the second cover body does not open to the first preset angle within a third preset time period during the process of the second cover body rotating relative to the shell to expose the light outlet.
