[0025] The fixing mechanism 2 includes a plurality of elastic bands 21, a shaping block 22 is fixedly installed between two elastic bands 21, an anti-skid pad 23 is fixedly installed on one side of the shaping block 22, a connecting block 24 is arranged on the fixing mechanism 2, and ends of the connecting blocks 24 which are away from each other are respectively fixedly connected to the shaping blocks 22, and Velcro 25 is respectively arranged between the two connecting blocks 24, and the two Velcro 25 have one fur surface and the other hook surface. By arranging the elastic bands 21 in conjunction with the shaping blocks 22, the fixing mechanism 2 can be better worn on the patient's neck, and the setting of the anti-skid pad 23 can improve the comfort of the patient when wearing it.
[0026] The mounting mechanism 3 includes an outer tube 31 fixedly mounted on the shaping block 22 on a side away from the anti-slip pad 23, an inner tube 32 is slidably mounted in the outer tube 31, a fixing rod 33 is fixedly mounted in the inner tube 32, support rods 34 are fixedly mounted on both sides of the fixing rod 33, and a limiting plate 35 is fixedly mounted on one end of the support rod 34 away from the fixing rod 33. By fixing the fixing rod 33 in the inner tube 32, the support rod 34 can be fixedly mounted in the inner tube 32, and the fixed setting of the support rod 34 can provide support for the pressing and sliding of the pressing tube 37.
[0027] A plurality of insertion holes 36 are respectively provided on the outer tube 31 and the inner tube 32, a pressing tube 37 is slidably installed in the insertion hole 36 on the inner tube 32, and the pressing tube 37 is sleeved on the support rod 34, the limiting plate 35 is located in the pressing tube 37, a spring 38 is sleeved on the support rod 34, and the two ends of the spring 38 are respectively connected to the fixing rod 33 and the pressing tube 37.

[0030] The fixing rod 33 is a rectangular rod. By setting the fixing rod 33 as a rectangular rod, the stability of the connection between the spring 38 and the fixing rod 33 can be increased, thereby increasing the stability of the spring 38 supporting the pressing tube 37 when pressing, thereby facilitating the disassembly and assembly between the collecting bottle 13 and the fixing mechanism 2.
[0031] The working principle of the saliva collector provided by the utility model is as follows:
[0032] When wearing, first separate the two Velcro strips 25, and make the fixing mechanism 2 fit the patient's neck better through the elasticity of the multiple elastic bands 21, then press the two opposite pressing tubes 37, adjust the relative position between the collecting bottle 13 and the fixing mechanism 2, insert the inner tube 32 into the outer tube 31, and then loosen the two pressing tubes 37, so that the two pressing tubes 37 are respectively inserted into the two opposite jacks 36 on the outer tube 31. The number of pressing tubes 37 can be set according to actual needs, and two are taken as an example here;
[0033] When in use, the inner tube 32 can be rotated by pressing the pressing tube 37, and then the collecting bottle 13 can be rotated to adjust the angle of the liquid receiving bucket 11 longitudinally, and the angle of the liquid receiving bucket 11 can also be adjusted laterally by rotating the drainage bucket 12. After the angle is adjusted, when the patient uses it, he spits saliva into the liquid receiving bucket 11, and the saliva flows into the drainage bucket 12 along the side wall of the liquid receiving bucket 11, and is drained into the collecting bottle 13 through the drainage bucket 12. During the saliva collection process, the amount of saliva in the collecting bottle 13 can be checked and recorded through the scale marks 14 corresponding to different angles on the collecting bottle 13. At the same time, the check valve arranged at the liquid outlet end of the drainage bucket 12 can effectively prevent the saliva flowing into the collecting bottle 13 from flowing back when the patient lies down to use the device. In addition, the liquid receiving bucket 11 can be replaced with a straw for use, such as Figure 4 As shown;
[0034] When the saliva in the collecting bottle 13 has collected to a certain extent and needs to be poured out, the pressing tube 37 can be pressed again to remove the collecting bottle 13 from the fixing mechanism 2, and then the saliva can be put back after the pouring is completed.
