An annular ring 302 is fixedly connected to the inner side of the top of the collecting tube 2. The annular ring 302 fits with the side of the guide plate 301 close to the collecting cover 1. The guide plate 301 can guide saliva to flow into the collecting tube 2. The annular ring 302 is made of rubber material. When the collecting tube 2 is inserted into the collecting cover 1, the annular ring 302 will deform when contacting the guide plate 301, thereby increasing the pressure between the guide plate 301 and the collecting tube 2 to prevent it from shaking. A scale is provided on the collecting tube 2.

[0027] A guide cover 4 is fixedly connected to the bottom of the collecting cover 1 ; the guide cover 4 can assist the collecting tube 2 to be smoothly inserted into the collecting cover 1 .

[0028] A snap-fit ​​block 6 is fixedly connected to one side above the middle of the collection cover 1, and a filter screen 7 is snap-fitted to the snap-fit ​​block 6. A pull ring 8 is fixedly connected to the top surface of the filter screen 7.

[0031] Working principle: Before using this anti-saliva splash saliva collector, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 4 As shown, firstly, the collecting tube 2 is inserted into the bottom of the collecting cover 1. At this time, the shell of the collecting tube 2 is inserted between the guide plate 301 and the collecting cover 1. At this time, the annular ring 302 fits the guide plate 301 to prevent the collecting tube 2 from shaking.

[0032] Then the collecting tube 2 is rotated, and when the barb block 307 approaches the engaging opening 303, the spring 306 pushes the rotating rod 304 to rotate, so that the barb block 307 is inserted into the engaging opening 303;

[0033] Then, the splash-proof cover 12 is opened, the filter screen 7 is inserted into the locking block 6, and the saliva is collected. Then, the filter screen 7 is removed and the retaining liquid is injected into the collection tube 2 until the retaining liquid reaches a suitable height;

[0034] When the collecting tube 2 needs to be disassembled, the pressing plates 305 on both sides are pressed simultaneously, so that the rotating rod 304 pulls the barb block 307 out of the engaging opening 303, and finally the collecting tube 2 is directly pulled out of the collecting cover 1, and then the tube cap of the collecting tube 2 is screwed on;

[0035] When the liquid in the collecting tube 2 needs to be taken out, the drain port 10 is pulled out from the rubber stopper 11 , and then the plastic cover 9 is continuously squeezed and pressed so that the sponge block 5 is squeezed, thereby allowing the liquid to be discharged from the drain port 10 .

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
