The second air channel 7 and the third air channel 10 are both connected with a pressure detection meter 9, and the pressure detection meter 9 is used for detecting the pressure of the discharging pipeline 5. The air outlet end of the third air channel 10 is provided with a switch valve 11 for controlling the speed and the opening and closing of the discharge pipeline 5 to the outside. The first air passage 6 and the second air passage 7 are both communicated with the switching module 8.

Referring to fig. 2, the switching module 8 includes a housing 801. The left side of the shell 801 is fixedly communicated with the first air passage 6, and the lower side of the shell 801 is fixedly communicated with the second air passage 7. The housing 801 is provided with an adjustment post 802 for the rotary seal. The lower end of the adjusting column 802 is provided with a second port 804, and the second port 804 is always communicated with the second air channel 7. The side wall of the adjusting column 802 is provided with a first through opening 803. The first port 803 is matched to the first air path 6. The first port 803 and the second port 804 communicate. An adjusting member 805 is rotatably provided on the housing 801, and the adjusting member 805 is fixedly connected to the adjusting post 802.

Referring to fig. 3, the switching valve 11 includes a body 1101 screw-rotatably provided with the third air passage 10. A slider 1103 is rotatably provided at the lower end of the body 1101. The slider 1104 is provided on both sides of the slider 1103.
