[0059] There are three lead screws 3-9, which are respectively fixed to the front end of the support shaft 3-7, and each lead screw 3-9 is fitted with a threaded tube 3-10 through a threaded connection.

[0060] The movable blocks 3-11 are three in number, each passing through a corresponding movable slot 3-3-1, and the front end of the threaded tube 3-10 is screwed into the corresponding movable block 3-11 via bearings.

[0061] Using the above design scheme, the rotating motor 3-1 rotates, causing the rotating frame 3-3 to rotate inside the box body 1, thereby shielding or ventilating the arc-shaped groove 1-2.

[0062] Example 3:

[0063] Please see Figures 1-7 Based on Embodiment 1, the rear ventilation assembly 4 is further improved and includes:

[0064] Two square blocks 4-1 are respectively set in corresponding square slots 1-3, and an operation slot 1-5 is opened on the rear inner wall of the box body 1, and the operation slot 1-5 is connected to the direction slot; the upper and lower sides of the operation slot 1-5 are both connected to the slot 1-6, and the upper and lower sides of the square block 4-1 are both fixed with rails 4-5, and the rails 4-5 are slidably set in the corresponding slots 1-6.

[0065] The operating motor 4-2 is fixed to the middle of the rear side of the housing body 1 and is connected to an external power supply.

Conversely, when the operating motor 4-2 rotates in the opposite direction, the upper toothed block 4-4 moves the square block 4-1 to the left, and the lower toothed block 4-4 moves the square block 4-1 to the right, until both square blocks 4-1 are disengaged from the square grooves 1-3 and placed in the operating groove 1-5, allowing the square blocks 4-1 to be in ventilation operation.

[0071] The beneficial effects of this specific embodiment after adopting the above structure are as follows:

[0072] 1. The movable block 3-11 cooperates with the rotating frame 3-3. When it is necessary to cover the arc groove 1-2, the movable block 3-11 can be inserted into the arc groove 1-2. When it is necessary to ventilate the arc groove 1-2, the rotating frame 3-3 drives the movable block 3-11 to move away from the arc groove 1-2.

[0073] 2. A guide gear 4-3 meshes with and drives the upper and lower tooth blocks 4-4 to move, so that the square block 4-1 moves in different directions, thereby covering or ventilating the square slot 1-3.
