[0024] The main body mechanism 1 also includes a connecting head 106, a connecting hole 107, a positioning block 108, a threaded rod 109, a first air duct 110 and a second air duct 111. The connecting head 106 is fixedly installed at the left end of the first ventilation duct 101, the connecting hole 107 is fixedly arranged at the inner end of the connecting head 106, the positioning block 108 is movably installed at the left end of the first ventilation duct 101, the threaded rod 109 is fixedly installed at the right end of the positioning block 108, the inner end of the connecting hole 107 is provided with a thread corresponding to the threaded rod 109, the first air duct 110 is fixedly arranged at the inner lower end of the first air outlet 104, and the first air duct 110 is fixedly connected to the air inlet end of the first air outlet 104. The second air duct 111 is fixedly arranged at the inner lower end of the second air outlet 105, and the second air duct 111 is fixedly connected to the air inlet end of the second air outlet 105. When the device is in use, the positioning block 108 can be held to rotate the threaded rod 109. Because the inner end of the connecting hole 107 is provided with a thread corresponding to the threaded rod 109, when it rotates, the threaded rod 109 will move to the left or right, thereby blocking the first air duct 110 and the second air duct 111 below the first air outlet 104 and the second air outlet 105, so as to adjust the wind force. It can be adjusted according to actual needs during use, which is more convenient when used.

At this time, the blocking ball valve 207 moves to the left to open the guide groove 208, thereby connecting the first guide cabin 201 and the second guide cabin 202. When the device is not taking in air, the internal telescopic rod 204 and the movable spring 205 will shrink due to the force from left to right, thereby causing the blocking ball valve 207 to move to the right to close the guide groove 208, thereby avoiding gas backflow after the device is used, resulting in a reduced service life of the device.

[0026] Working principle: When the device is in use, the positioning block 108 can be held to rotate the threaded rod 109, because the inner end of the connecting hole 107 is provided with a thread corresponding to the threaded rod 109. When it rotates, the threaded rod 109 will move to the left or right, thereby blocking the first air duct 110 and the second air duct 111 below the first air outlet 104 and the second air outlet 105, so as to adjust the size of the wind force. It can be adjusted according to actual needs during use, which is more convenient when in use. When the device is taking in air, the internal telescopic rod 204 and the movable spring 205 will stretch and store elastic force. At this time, the blocking ball valve 207 moves to the left to open the guide groove 208, thereby connecting the first guide chamber 201 and the second guide chamber 202. When the device is not taking in air, the internal telescopic rod 204 and the movable spring 205 will shrink due to the force from left to right, thereby causing the blocking ball valve 207 to move to the right and close the guide groove 208, thereby preventing gas from flowing back after the device is used, which would reduce the service life of the device.

[0027] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
