[0034] As an embodiment of the present invention, the left end of the air inlet pipe 29 is connected to the filter cartridge 20, and the air inlet pipe 29 is fixedly connected to the filter cartridge 20. A second columnar groove is opened on the left side of the filter cartridge 20, and a filter screen 27 is installed at the notch of the second columnar groove. The right side of the filter screen 27 is elastically connected to the inner wall of the second columnar groove through a connecting spring 28.

An alarm 32 is installed on the rear side of the box body 1, and the alarm 32 is electrically connected to the touch delay switch 31. When the touch delay switch 31 is triggered, the alarm 32 will sound an alarm.

[0035] In the present invention, when in use, the user sits on the seat board 3, and rehabilitation training can be performed for two users at a time. Then, the user puts the eye close to the corresponding eyepiece 2, and then starts the two display panels, and starts the driving motor 5 at the same time. After the driving motor 5 is started, it will drive the reciprocating screw 10 to rotate, and the rotation of the reciprocating screw 10 will drive the slider to reciprocate back and forth.

[0037] Furthermore, the rotation of the reciprocating screw 10 will drive the rotating shaft 21 to rotate, and the rotation of the rotating shaft 21 will drive the rotating disk 18 to rotate. The rotation of the rotating disk 18 will allow the piston plate 24 to reciprocate left and right through the connecting shaft 23. The reciprocating movement of the piston plate 24, in conjunction with the use of the first one-way valve 25 and the second one-way valve 26, will generate a one-way gas flow between the outside, the filter cartridge 20, the right side space of the first columnar groove 22, the exhaust pipe 33, the display housing 12, the heat dissipation hole 8 and the outside. The gas flow can promote the heat dissipation inside the display housing 12. In addition, the filter screen 27 can be used to filter the incoming dust to prevent the external dust from entering the inside of the display housing 12.

[0038] In addition, when a lot of dust accumulates on the filter 27, the flow of gas will cause the filter 27 to move to the right and contact the touch delay switch 31, thereby triggering the alarm 32 to sound an alarm, reminding the staff to clean the filter 27 immediately.
