Specifically, as shown in fig. 1, 2 and 4, the double circulation air path structure 20 includes a housing 21, a blower 22, and a switching mechanism 23. The bottom surface of casing 21 is provided with air outlet 212 and first air intake 211, and air outlet 212 and first air intake 211 can be with waiting the inside intercommunication of ventilation area, and the side of casing 21 is provided with second air intake 213. The second air inlet 213 can communicate with the outside of the region to be ventilated; part of the fans 22 are arranged in the shell 21, and after the fans 22 are started, air flows can be driven to enter the shell 21 from the first air inlet 211 or the second air inlet 213 and are discharged from the air outlet 212 so as to ventilate the area to be ventilated; the switching mechanism 23 includes a baffle 231 rotatably disposed in the housing 21, and when the baffle 231 can block one of the first air inlet 211 and the second air inlet 213, the other of the first air inlet 211 and the second air inlet 213 is closed, so as to switch the air inlets of the dual circulation air path structure 20.

When the second air inlet 213 is closed by the baffle 231 and the first air inlet 211 is opened, as shown in fig. 1-3, the air is introduced into the first air inlet 211 communicated with the outside of the region to be ventilated, and then the air in the region to be ventilated enters the housing 21 through the first air inlet 211, and then is introduced into the region to be ventilated through the air outlet 212, so as to form an internal circulation, i.e. the air in the region to be ventilated circulates.

When the baffle 231 closes the first air inlet 211 and opens the second air inlet 213, as shown in fig. 4-6, the air is introduced into the region to be ventilated through the second air inlet 213 communicating with the outside of the region to be ventilated, and the air flow in the housing 21 is introduced into the region to be ventilated through the air outlet 212 to form an external circulation, i.e. the external fresh air is introduced into the region to be ventilated.

The dual circulation air path structure 20 provided in this embodiment can realize the inner circulation flow and the outer circulation flow of the air flow. When the internal circulation is adopted, the air flow in the area to be ventilated can be circulated, so that the energy (such as heat) of the air flow in the area to be ventilated can be fully utilized; when external circulation is adopted, fresh air can be introduced into the region to be ventilated to change environmental parameters (such as temperature and humidity) in the region to be ventilated.

In this embodiment, the baffle 231 is rotatably disposed in the housing 21, so that the air inlet can be switched more quickly and conveniently.

Specifically, opposite ends of the housing 21 along the first direction X are an air inlet end and an air outlet end, the first air inlet 211 and the second air inlet 213 are disposed at the air inlet end, the air outlet 212 is disposed at the air outlet end, the fan 22 is disposed between the air inlet end and the air outlet end, and an axial direction of the fan 22 extends along the second direction Y; the top surface and the bottom surface of the housing 21 are disposed at intervals along a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. This arrangement can ensure that the air flow flows in the first direction in the housing 21 when any air intake mode is adopted, thereby realizing the circulation flow of the air flow.

In order to further simplify the internal structure of the housing 21, the first air inlet 211 is disposed on the bottom surface of the housing 21, the second air inlet 213 is disposed on a side surface of the housing 21 adjacent to the bottom surface, and the side surface of the second air inlet 213 is disposed perpendicular to the first direction X. By the arrangement, the bottom surface of the first air inlet 211 is vertically connected with the side surface of the second air inlet 213, and one end of the baffle 231 is rotatably arranged at the connection position of the bottom surface and the side surface of the second air inlet 213. As shown in fig. 2, when the baffle 231 is parallel to the third direction Z, the baffle 231 is applied to the side surface of the second air inlet 213 to block the second air inlet 213 and open the first air inlet 211; as shown in fig. 5, when the baffle 231 is parallel to the first direction X, the baffle 231 is attached to the bottom surface to block the first air inlet 211 and open the second air inlet 213.

The shutter 231 can be driven to rotate by the reciprocating rotation of the rotation shaft 232, so that the position between the first air inlet 211 and the second air inlet 213 is switched.

Further, the drive assembly 233 includes a motor 2332, a drive pulley 2333, a driven pulley 2334, and a drive belt 2335. The motor 2332 is arranged on the shell 21, and an output shaft of the motor 2332 is connected with the driving wheel 2333. The driven wheel 2334 is connected with one end of the rotating shaft 232, and the driving belt 2335 is in transmission connection with the driven wheel 2334 and the driving wheel 2333. When the motor 2332 is started, the driving wheel 2333 can be driven to rotate through the rotation of the output shaft of the motor 2332, so that the driven wheel 2334 and the rotating shaft 232 are sequentially driven to rotate through the transmission belt 2335, and the position switching of the baffle 231 is realized.

In order to increase the internal space of the housing 21 as much as possible without increasing the size of the housing 21, the driving assembly 233 is disposed outside the housing 21. Specifically, the motor 2332 is disposed on an outer wall of the housing 21, and one end of the rotation shaft 232 protrudes out of the housing 21 to be connected with the driven wheel 2334.

In order to reduce the size of the shaft 232 extending out of the housing 21, thereby reducing the length of the shaft 232 to improve the strength of the shaft 232, the output shaft of the motor 2332 is disposed toward the housing 21, so that the length of the shaft 232 extending out of the housing 21 is sufficient for mounting the driven wheel 2334.

For the convenience of motor 2332 being connected with casing 21, drive assembly 233 still includes support 2331, and support 2331 includes fixed cover and two at least stabilizer blades, and motor 2332 sets up in fixed cover, and stabilizer blade one end is connected with fixed cover, and the other end can be fixed on casing 21 through fastener such as screw.
