[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Example

[0019] See also Figure 1-3 The present invention provides a technical solution: a multi-purpose oral waste gas collection device, comprising an outer bell mouth 1, an inner bell mouth 2 is arranged inside the outer bell mouth 1, a pipe 11 is arranged at the bottom of the outer bell mouth 1, a through hole is opened at the bottom of the inner bell mouth 2, the through hole is connected with the pipe 11, a gap is left between the inner bell mouth 2 and the outer bell mouth 1, the gap is connected with the pipe 11, a sealing plug 7 is installed at the through hole at the bottom of the inner bell mouth 2, specifically, the sealing plug 7 is detachably connected to the inner bell mouth 2, the side wall of the sealing plug 7 is in contact with the inner wall of the inner bell mouth 2, a collecting groove is opened on the top surface of the sealing plug 7, a connecting pipe 8 is passed through the top surface of the sealing plug 7, and the connecting pipe 8 is connected with the pipe 11.

[0020] In this embodiment, during oral treatment, the device is placed near the patient's mouth, and the aerosol generated during the treatment is sucked. When the aerosol comes into contact with the inner wall of the inner bell mouth 2, it condenses into water droplets due to the Coanda effect and flows along the inner wall of the inner bell mouth 2 to the collection tank. The gas passes through the gap between the inner bell mouth 2 and the outer bell mouth 1 and the connecting tube 8 and enters the pipe 11. During the process, the patient can spit or saliva, which is collected in the collection tank and finally processed centrally by removing the sealing plug 7.

[0021] Furthermore, a filter screen is provided on the top of the connecting pipe 8 .

[0022] In this embodiment, it is convenient to isolate debris through the filter.

[0023] Furthermore, a lip 3 is provided at the top of the outer bell mouth 1, and the lip 3 is arranged in a ring shape. A clamping block 5 is provided on the bottom surface of the lip 3. Specifically, the clamping block 5 and the lip 3 are an integrated structure. A clamping slot 4 is provided at the top of the inner bell mouth 2, and the clamping block 5 is cooperatively connected with the clamping slot 4. Specifically, the clamping block 5 is inserted in the clamping slot 4.

[0024] In this embodiment, the inner bell mouth 2 is fixed by the cooperation between the clamping block 5 and the clamping slot 4 .

[0025] Furthermore, an insert block 10 is provided on the bottom surface of the lip 3. Specifically, the insert block 10 and the lip 3 are an integral structure. An insert hole 9 is provided on the top edge of the outer bell mouth 1. The insert block 10 is cooperatively connected with the insert hole 9. Specifically, the insert block 10 is inserted in the insert hole 9.

[0026] In this embodiment, the lip 3 is fixed by the cooperation between the mounting block 10 and the insertion hole 9, and the lip 3 is set, and the aerosol contacts the inner wall of the inner bell mouth 2. Due to the Coanda effect, the condensed water droplets will not flow back.

[0027] Furthermore, a protrusion is provided at the bottom of the outer bell mouth 1 below the inner bell mouth 2, and a stepping block 6 is provided at the bottom of the inner bell mouth 2. Specifically, the stepping block 6 and the inner bell mouth 2 are an integral structure, and the stepping block 6 is placed on the protrusion.

[0028] In this embodiment, the building block 6 is built on the protrusion, so that the gap between the inner bell mouth 2 and the outer bell mouth 1 can be kept connected with the channel 11.

[0029] Furthermore, the end of the pipeline 11 is connected to a negative pressure suction device.

[0030] In this embodiment, suction is performed by a negative pressure suction device.
