[0030] A cleaning mechanism 7 is arranged inside the main frame 1 above the connecting block 2, and the cleaning mechanism 7 includes a rotating block 701, a cleaning roller 702, a fixed block 703 and a scraper 704.

The cleaning roller 702 is used to clean the outer screen surface of the projector body 5 to prevent dust accumulation from affecting the interactive effect and display effect of the projector body 5.

[0031] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 A dust discharge mechanism 8 is provided at the bottom of both sides of the main frame 1, and the dust discharge mechanism 8 includes a side frame 801, a motor 802, a threaded rod 803 and a cleaning plate 804. The side frame 801 is fixedly connected to the outer side of the main frame 1, and the motor 802 is fixedly connected to one side of the side frame 801 by bolts. One end of the threaded rod 803 is fixedly connected to the output end of the motor 802, and the cleaning plate 804 is threadedly connected to the threaded rod 803. A sealing door 9 is provided on the front side of the main frame 1. By starting the motor 802, the cleaning plate 804 is driven to move to push the dust inside the main frame 1, so that the staff can regularly open the sealing door 9 to deal with the dust at the bottom of the main frame 1, which is convenient and quick.

[0032] See also Figure 4 The scraper 704 is of an inclined shape, and the scraper 704 is the same length as the cleaning roller 702, so that the dust falling onto the scraper 704 can slide to the bottom of the main frame 1.

[0033] See also Figure 2 The fixing block 703 is made of stainless steel, and one side of the fixing block 703 is fixedly connected to the main frame 1 by bolts to avoid the fixing block 703 from breaking, and the fixing block 703 can be disassembled by rotating the thread.

[0034] See also Figure 1 and Figure 3The cleaning plate 804 is slidably connected to the side frame 801, and the cleaning plate 804 is slidably connected to the sliding grooves on both sides of the main frame 1 to ensure the stability of the cleaning plate 804 during movement.

[0035] See also Figure 1 A rubber pad is fixedly connected to the bottom of the cleaning plate 804, and the rubber pad fits the bottom of the inner side of the main frame 1, so that the cleaning plate 804 can push the dust at the bottom of the main frame 1 to move.

[0036] See also Figure 1 A telescopic rod 6 is fixedly connected to the lower part of the installation frame 3, and the output end of the telescopic rod 6 is fixedly connected to the bottom of the projector body 5 to ensure the stability of the projector body 5 during the rising or falling process.

[0037] Working principle: first, when the projector needs to be used, start the pneumatic cylinder 4. The pneumatic cylinder 4 will push the projector body 5 to move upward. The outer screen of the projector body 5 fits with the bristles of the cleaning roller 702. Therefore, when the projector body 5 moves upward, the bristles of the cleaning roller 702 will clean the outer screen of the projector body 5. During the cleaning process, the cleaning roller 702 will rotate under the action of the friction between the bristles and the outer screen. Since one end of the scraper 704 is embedded in the bristles of the cleaning roller 702, when the cleaning roller 702 rotates, the scraper 704 will clean the bristles of the cleaning roller 702. The dust separated from the bristles falls to the top of the scraper 704 under the influence of gravity. Since the scraper 704 is an inclined surface, the dust will eventually enter the bottom of the main frame 1 under the influence of gravity, and the outer screen of the unfolded projector body 5 will be cleaned by the cleaning roller 702 to prevent dust from affecting the display effect and interactive effect of the projector body 5.

[0038] Secondly, when the projector body 5 needs to be stored, the pneumatic cylinder 4 is started again, and the pneumatic cylinder 4 drives the projector body 5 to descend. When the projector body 5 descends, the outer screen will contact the bristles of the cleaning roller 702, and the bristles of the cleaning roller 702 will clean the outer screen of the projector body 5 being stored, so as to prevent dust from affecting the subsequent use of the projector body 5;

[0039] Finally, when it is necessary to clean the dust at the bottom of the inner side of the main frame 1, the staff puts the dustpan in front of the sealing door 9, manually opens the sealing door 9, and then starts the motor 802. The operation of the motor 802 will drive the threaded rod 803 to rotate. Since the cleaning plate 804 is slidingly connected to the side frame 801, the side frame 801 will limit the cleaning plate 804 to a certain extent. When the threaded rod 803 rotates, it will drive the cleaning plate 804 to move under the influence of the thread. The rubber pad at the bottom of the cleaning plate 804 fits with the bottom of the main frame 1. Therefore, the movement of the cleaning plate 804 will drive the dust at the bottom of the inner side of the main frame 1 to move, and the cleaning plate 804 will push the dust to be discharged through the sealing door 9 and fall into the dustpan. It is convenient and quick, and it is convenient for the staff to regularly clean the dust inside the main frame 1.
