[0014] Preferably, the handle assembly includes a handle body and a handle cover, the handle cover being fixedly connected to the handle body.

[0015] Beneficial effects:

[0016] 1. This utility model provides a negative pressure suction device for the throat. By setting a conical surface at one end of the mask connector, the contact area with the mask is increased. During operation, the device can be pressed on the conical surface of the mask connector. At this time, the force-bearing component changes from the mask to the mask connector, thereby avoiding excessive force that could cause the mask to separate from the mask connector.

[0017] 2. This utility model makes the structure of the negative pressure suction device more robust by connecting the airbag connector and the airbag with threads, and by connecting the mask connector and the airbag connector with threads. Attached Figure Description

Detailed Implementation

[0024] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0025] Example 1:

[0026] Provided such as Figure 1-4 The pharyngeal negative pressure suction device shown includes: a handle assembly 1, an airbag assembly 2, a mask connector 3, and a mask 4. The handle assembly 1 is threadedly connected to the airbag assembly 2, the airbag assembly 2 is threadedly connected to the mask connector 3, the mask connector 3 is matingly connected to the mask 4, and a conical surface 33 is provided at one end of the mask connector 3 that is connected to the mask 4.

[0027] The airbag assembly 2 includes an airbag 21, a first airbag connector 22, and a second airbag connector 23, which are located at both ends of the airbag 21. The first airbag connector 22 is threadedly connected to the handle assembly 1, and the second airbag connector 23 is threadedly connected to the airbag 21. A first sealing ring 5 is provided between the first airbag connector 22 and the handle assembly, a second sealing ring 6 is provided between the first airbag connector 22 and the airbag 21, and a third sealing ring 7 is provided between the second airbag connector 23 and the airbag 21. The handle assembly 1 has a groove for placing the first sealing ring 5 to seal the handle assembly 1 and the first airbag connector 22. The airbag connectors 22 and 23 have grooves inside for placing the second sealing ring 6 and the third sealing ring 7 to seal the airbag 21.

[0028] The mask connector 3 and the second airbag connector 23 are connected by threads. A fourth sealing ring 8 is provided between the mask connector 3 and the second airbag connector 23. The mask connector 3 is provided with a groove for placing the fourth sealing ring 8 to seal between the mask connector 3 and the second airbag connector 23.

[0029] A vent 31 is provided on the side wall of the mask connector 3, and a one-way valve 32 is provided inside the vent 31.

[0030] The face mask 4 includes a connecting part 41 and a fitting part 42.
