[0025] In the embodiment, a plurality of air inlet holes 405 are equidistantly opened in the top circumferences of air cylinder 4, a fixed column 406 is fixedly connected with the inside of the top of air cylinder 4, and a rubber sheet 407 is fixedly connected with the circumferential surface of fixed column 406 close to the top, so that the air inlet holes 405 in the top of air cylinder 4 can only intake air through the setting of air inlet holes 405 and rubber sheet 407, and the rubber sheet 407 is compatible with the plurality of air inlet holes 405, the circumferential surface of square air blowing rod 401 in the inside of air cylinder 4 is sleeved with a spring 403, the setting of spring 403 facilitates the release and reset of piston 402, and a convex rod 404 is fixedly connected with the outside of square air blowing rod 401 close to the bottom of air cylinder 4.

[0026] In the embodiment, a fixed ring 5 is fixedly connected with the top of air cylinder 4, a protective cover 501 is screwed with the top of fixed ring 5, and a HEPA net 502 is fixedly connected with the middle of protective cover 501, so that viruses and bacteria in the air outside cannot enter the inside of air cylinder 4.

[0027] In the embodiment, a motor 302 is fixedly connected with the end of screw sleeve 3 away from powder feeding pipeline joint 301, a rotating rod 305 is fixedly connected with the output end of motor 302 penetrating screw sleeve 3, and a worm 306 is fixedly connected with the circumferential surface of rotating rod 305 in the inside of screw sleeve 3.

[0028] In the embodiment, a feeding hopper 303 is fixedly connected with the end of screw sleeve 3 close to motor 302, a round rod 307 is fixedly connected with the end of rotating rod 305 close to powder feeding pipeline joint 301, and a volute-shaped convex block 308 is fixedly connected with the other end of round rod 307.

[0029] In this embodiment, the volute-shaped protrusion 308 is adapted to the convex rod 404.

[0030] Working principle: when in use, start the motor 302, so that the rotating rod 305 rotates with the auger 306, realizing the conveying of the raw powder. Through the setting of the powder conveying pipe joint 301 and the vertical joint 2, the raw powder input from the screw sleeve 3 can smoothly enter the powder box 1. Compared with the traditional joint, such a setting makes it possible that when the auger 306 in the screw sleeve 3 stops working, there will be no accumulation of a large amount of residual powder in the vertical joint 2. At the same time, in order to avoid the residual powder remaining on the inner wall of the vertical joint 2 when the screw sleeve 3 works at the same time, the rotation of the rotating rod 305 driven by the motor 302 makes the rotation of the round rod 307 and the volute-shaped protrusion 308. Due to the action of the volute-shaped protrusion 308 and the convex rod 404, the initial position of the convex rod 404 is below the round rod 307. When the volute-shaped protrusion 308 rotates with the round rod 307, the volute-shaped protrusion 308 will push the convex rod 404 to descend with the square air blowing rod 401, thereby compressing the spring 403. At the same time, when the piston 402 descends, the space inside the air cylinder 4 at the top will produce negative pressure, so that the outside air enters the inside of the air cylinder 4 through the air inlet hole 405. The setting of the rubber sheet 407 makes the outside air enter the inside of the air cylinder 4, but the inside air cannot go out from the air inlet hole 405. The setting of the HEPA net 502 makes bacteria and viruses unable to enter the powder conveying pipe joint 301 through the air inlet hole 405. When the volute-shaped protrusion 308 rotates with the round rod 307 by a certain angle, the convex rod 404 is separated from the volute-shaped protrusion 308. At this time, under the action of the spring 403, the piston 402 quickly rises, and the air inside the air cylinder 4 at the top can only push the light sheet 410 to rotate through the air outlet hole 409, so that the air inside the air cylinder 4 enters the square air blowing rod 401 through the air outlet hole 409, and finally blows out from the bottom, so that the raw powder on the inner wall of the vertical joint 2 cannot adhere to the vertical joint 2, but directly enters the powder box 1. When the feeding hopper 303 supplies material at the same time, continue to start the motor 302, and the continuous blowing of the square air blowing rod 401 makes it possible that there is no residual powder in the vertical joint 2.
