[0003] In order to improve the air quality in the elevator, the prior art mostly adds an air circulation system to the car to process the air entering the car, but the equipment required for the air circulation system is all installed on the car, which increases the weight of the car and is not conducive to operation.

[0004] For example, the Chinese utility model patent CN218950757U discloses an "elevator car air circulation system to prevent occupants from hypoxia", and its specification discloses: including an elevator car and a mounting frame, the mounting frame is mounted on the upper inner side of the elevator car, and the upper end of the elevator car is provided with a plurality of ventilation holes, and also includes: a ventilation assembly, the ventilation assembly is mounted on the middle of the upper end of the mounting frame and is located directly below the ventilation holes; an oxygen humidity monitoring assembly, the oxygen humidity monitoring assembly is mounted on the right upper end of the mounting frame; an oxygen production assembly, the oxygen production assembly is mounted on the left upper end of the mounting frame and is connected to the ventilation assembly; a humidification assembly, the humidification assembly is mounted on the right lower end of the mounting frame and is connected to the ventilation assembly. The above patents can prove the defects of the prior art.

[0005] Therefore, we have made improvements to this and proposed an air circulation system, an incubator and a villa elevator. Summary of the invention

[0094] The second support seat 210 and the first support seat 209 are both provided with two slots 212 on the side away from the supporting mechanism 3. Figure 3 In this state, the corresponding support seat 210 can be limited by inserting the vertical rod 203 into the corresponding slot 212, thereby facilitating the insertion of the bearing mechanism 3. Fig. 9 In this state, the position of the connection seat 206 can be fixed by inserting the bolt 205 into the insertion hole 207 .

[0096] When in use, hold the handle 302 and turn the hand wheel to rotate the bidirectional screw rod 201, and the bidirectional screw rod 201 drives the two sliders 202 to move away from each other, thereby separating the tray 301 from the corresponding support seat 210. After unscrewing the bolt 205, screw the bolt 205 into the screw hole 204 of the corresponding height, and insert the bolt 205 into the slot 212 of the required height. At this time, there is a space between the two corresponding support seats 210. Turn the hand wheel in the opposite direction to make the two sliders 202 approach each other. At this time, the side of the tray 301 is inserted into the space between the two support seats 210, and the tray 301 is supported by the support seat 1 209 and the corresponding support seat 210, that is, the height adjustment of the tray 301 is completed;

[0097] The handle 302 is held and the hand wheel is turned to rotate the bidirectional screw rod 201, which drives the two sliders 202 to move away from each other, thereby separating the tray 301 from the corresponding support seat 210, lowering the tray 301 to the bottom, unscrewing the bolt 205 and pushing the connecting seat 206 upward so that the insertion hole 207 is aligned with the uppermost screw hole 204, and the bolt 205 is inserted into the insertion hole 207 and the screw hole 204 to fix the position of the connecting seat 206. At this time, the adapter plate 208 is rotated to stand upright, pushing the support seat 210 so that the support seat 210, the connecting plate 211 and the support seat 1 209 are covered at the top of the inner cavity of the box body 1, that is, Figure 8 At this time, the box body 1 and the supporting mechanism 2 can form a protective structure for the plants, so that the box body 1 can protect the plants therein after being taken out of the villa elevator, which is suitable for plants with small height;

[0098] When it is necessary to reset, push the second support seat 210 toward the first support seat 209, then stand the first support seat 209 and the second support seat 210 upright, unscrew the bolt 205, lower the connecting seat 206 to the lower position, and then screw the bolt 205 into the corresponding screw hole 204 and the slot 212, and then insert the side of the tray 301 into the space between the two second support seats 210.
