[0016] The technical solution of the present invention is further described below by way of embodiments:

[0017] The utility model provides a vacuum suction device, combined with Figures 1 to 3 As shown, the vacuum suction device includes a vacuum suction device body 1, an adapter 2 and a muffler 3. The vacuum suction device body 1, the adapter 2 and the muffler 3 are connected in sequence, and the muffler 3 is arranged perpendicular to the adapter 2. The side wall of the vacuum suction device body 1 is provided with an air inlet, and an end cover 11 of the vacuum suction device body 1 is provided with an exhaust port and is fixedly connected to the adapter 2 through the end cover 11. One end of the adapter 2 is provided with an input hole connected to the exhaust port, and the other end is provided with an output hole.

[0018] In this embodiment, the adapter 2 and the end cover 11 are connected by screws. In other embodiments, they can also be connected by other connecting members as long as the adapter 2 and the end cover 11 can be fixedly connected.

[0019] Specifically, a passage is provided inside the adapter 2 , a first through hole 21 is provided on a side wall of the adapter 2 , and the muffler 3 is communicated with the adapter 2 through the first through hole 21 .
