[0025] The projector adjustment method based on human motion recognition comprises the following steps:

[0026] Step 1: Correction processing, the operator swings his arm left and right, then the rotator will rotate with the deflection of the arm, and finally drive the projector to deflect together, so that the projection angle is corrected;

When the operator puts down his arm, the entire cleaning assembly will return to its original state. Therefore, during the recovery process, the cleaning ring brush will add cleaning liquid to the lens again. This step avoids the situation where too little cleaning liquid is applied at the beginning, which makes it impossible to remove the stains and adhesions. Finally, the cleaning ring brush will wipe off the cleaning liquid and stains on the lens surface.

[0032] 2. When the operator pushes the moving plate forward, the support plate connected to the moving plate through the inner rod will carry the adapter and move forward along the fixed rail, thereby focusing the projector normally and avoiding distortion.

[0033] 3. The compensation cover ring extends out from the protective cover, and the center strip fixedly connected to the inner end of the compensation cover ring will stretch the elastic sheet outward together, thereby playing a role in dust prevention and protection of the moving projector.

[0034] 4. A small amount of dust adheres to the bottom side of the inner cavity of the dust receiving frame. At this time, hot air is introduced into the bottom of the dust receiving frame, causing a small amount of dust to be affected by the wind and enter the interior of the dust receiving frame along the bottom of the air duct plate, thereby achieving the dual processing effects of dust collection and heat dissipation.

When the operator approaches the movable plate 13, the infrared sensor 203 cannot focus and cannot sense the movement of the human body. At this time, the operator can push the movable plate 13 forward. At this time, the support plate 20 connected to the movable plate 13 through the inner rod 15 will carry the adapter 22 and move forward along the fixed rail 21, so as to focus the projector 24 normally and avoid distortion.

[0057] The top of the adapter 22 is fixedly connected with a support plate 20 and a rotation limiting plate 201, the outer side of the support plate 20 is fixedly connected to the inner connecting rod 15, the inner side of the rotation limiting plate 201 is extruded and adapted with a double-headed rod 202, the bottom end of the double-headed rod 202 is fixedly connected to the outer side of the rotator 23, and the top end of the double-headed rod 202 is fixedly connected to the bottom of the projector 24.

The heat outlet pipe 254 is fixedly installed on the top of the projector 24. A motor 255 is fixedly installed inside the heat outlet pipe 254. The output end of the motor 255 is connected to the fan 256 through a coupling. An arc piece 259 is fixedly connected to the inner side of the dust collecting frame 253. A connecting strip 257 is fixedly connected to the bottom of the annular net 251. The bottom end of the connecting strip 257 is fixedly connected to an air induction plate 258. As the projector 24 is started, heat is generated inside the projector 24, and the heat is discharged from the heat outlet pipe 254. At this time, the motor 255 is started, so that the fan 256 connected to its output end through the coupling will rotate and introduce the hot air toward the bottom of the dust receiving frame 253, wherein some dust will enter from the conical hole 252 opened at the top of the annular net 251, wherein the top diameter of the conical hole 252 is larger than the bottom diameter, thereby making it difficult for the dust to return from the conical hole 252 and be discharged outward. At this time, most of the dust entering will be collected by the arc piece 259 and enter the interior of the dust receiving frame 253. The function of the arc piece 259 is the same as that of the conical hole 252. However, a small amount of dust will adhere to the bottom side of the inner cavity of the dust receiving frame 253.

A return spring 260 is fixedly connected to one side of the cleaning ring brush 269 away from the tension bar 264, and a square plate 2601 is fixedly connected to one end of the return spring 260 away from the cleaning ring brush 269. The square plate 2601 is fixedly connected to the inner end surface of the projector 24. The inner rotation of the cleaning ring brush 269 is connected to a central axis 2602. A cleaning ring brush 2603 is fixedly connected to the top of the cleaning ring brush 269. An injector 2604 is arranged between the cleaning ring brush 2603 and the cleaning ring brush 269. The injector 2604 and the central axis 2602 are both fixedly connected to the inner end surface of the projector 24. A ring fixing plate 2605 is fixedly connected to one end of the injector 2604 away from the projector 24, and a cotton body 2606 is fixedly connected to one side of the ring fixing plate 2605 away from the injector 2604.When the operator deflects the arm downward and keeps it still, the infrared sensor 203 will capture and receive the action, and then transmit the signal to the control terminal 204 for analysis and processing. The control terminal 204 will then transmit the analyzed signal to the small motor 261. At this time, the small motor 261 will start and rotate clockwise with the round roller 263 connected to it through the coupling. The outer side of the round roller 263 is fixedly connected to the tension bar 264, so the tension bar 264 will The cleaning brush 269 is wound on the round roller 263, and the other end of the tension bar 264 is connected to the cleaning ring brush 269, so the cleaning ring brush 269 will deflect counterclockwise with the central axis 2602 as the fulcrum and stretch the reset spring 260, wherein the reset spring 260 plays a role in resetting the cleaning ring brush 269. At the same time, the second magnetic block 268 fixedly connected to the bottom side of the tension bar 264 will move away from the first magnetic block 267, wherein the second magnetic block 268 and the first magnetic block 267 maintain an attractive relationship, and the two play a role in pulling. The force bar 264 restores its original state and position without being affected by external forces, and then the rotating cleaning ring brush 269 performs preliminary dust cleaning on the lens of the projector 24. Subsequently, the cleaning ring brush 2603 fixedly connected to the top of the cleaning ring brush 269 will deflect downward. During the downward deflection of the cleaning ring brush 2603, it will pass through the cotton body 2606, wherein the interior of the cotton body 2606 is poured with cleaning liquid by the injector 2604.

When the operator puts down his arm, the entire cleaning assembly 26 will return to its original state. Therefore, during the recovery process, the cleaning ring brush 2603 will add cleaning liquid to the lens again. This step avoids the purpose of applying too little cleaning liquid at the beginning, which makes it impossible to remove stains and adhesions. Finally, the cleaning ring brush 269 will play a role in wiping the cleaning liquid and stains on the surface of the lens.

[0063] The control terminal 204 consists of three parts: a receiving unit, a processing unit and an output unit;

[0064] Receiving unit: receives human motion information sensed by infrared;

[0065] Processing unit: analyzes and processes human motion information;

[0066] Output unit: outputs the signal transmitted by the processing unit.

[0067] When the present invention is in use: first, the operator swings his arm left and right, and then the infrared sensor 203 captures and receives the action, and then transmits the signal to the control terminal 204 for analysis and processing. Then the control terminal 204 transmits the analyzed signal to the rotator 23, and the rotator 23 rotates along with the deflection of the arm. When the operator deflects the arm downward and keeps it still, the infrared sensor 203 will capture and receive the action, and then transmit the signal to the control terminal 204 for analysis and processing. Then the control terminal 204 will transmit the analyzed signal to the small motor 261. At this time, the small motor 261 will start and rotate clockwise with the round roller 263 connected to it through a coupling. The outer side of the round roller 263 is fixedly connected to the tension bar 264, so the tension bar 264 will be wound on the round roller 263, and the other end of the tension bar 264 is connected to the cleaning ring brush 269, so the cleaning ring brush 269 will deflect counterclockwise with the central axis 2602 as the fulcrum, and stretch the reset spring 260, while the reset spring 260 is fixedly connected to the tension bar 264. The second magnetic block 268 on the bottom side will move away from the first magnetic block 267, and then the rotating cleaning ring brush 269 will perform preliminary processing on the lens of the projector 24, and then the cleaning ring brush 2603 fixedly connected to the top of the cleaning ring brush 269 will deflect downward, and in the process of the downward deflection of the cleaning ring brush 2603, it will pass through the cotton body 2606, wherein the interior of the cotton body 2606 is poured with cleaning liquid by the injector 2604, so the cleaning ring brush 2603 with cleaning liquid will add cleaning liquid to the surface of the lens, and when the operator puts down his arm, the entire cleaning assembly 26 will return to its original state, so in the recovery process, the cleaning ring brush 2603 will add cleaning liquid to the lens again, and finally the cleaning ring brush 269 will wipe the cleaning liquid on the surface of the lens.

[0068] When the operator approaches the movable plate 13, the infrared sensor 203 cannot focus and cannot sense the movement of the human body, and the operator can push the movable plate 13 forward at this time, and the support plate 20 connected to the movable plate 13 through the inner connecting rod 15 will carry the adapter 22 and move forward along the fixed rail 21, so that the projector 24 can be normally focused and distortion can be avoided. In addition, as the inner connecting rod 15 moves forward, the multi-folding rod 14 symmetrically connected on both sides thereof will move forward with the thin connecting rod 16, and the other end of the thin connecting rod 16 is connected to the compensation cover ring 10, and the compensation cover ring 10 is inserted into the inside of the protective cover 18, so the compensation cover ring 10 will extend from the protective cover 18, and at the same time, the center bar 101 fixedly connected to the inner end of the compensation cover ring 10 will stretch the elastic sheet 102 and extend outward together to realize the protection treatment of the projector 24.

[0069] As the projector 24 is started, heat is generated inside it, and this heat is discharged from the heat outlet pipe 254. At this time, the motor 255 is started, so that the fan 256 connected to its output end through the coupling will rotate, and the hot air will be introduced toward the bottom of the dust receiving frame 253, wherein some dust will enter from the conical hole 252 opened at the top of the annular net 251. At this time, most of the dust entering will be collected by the arc sheet 259 and enter the interior of the dust receiving frame 253, but a small amount of dust will adhere to the bottom side of the inner cavity of the dust receiving frame 253.
