An adjusting hole is formed in the adjusting frame 504. A liquid level sensor 505 is fixedly installed on the adjusting frame 504. The liquid level sensor 505 penetrates through the adjusting hole. When the oral fluid preservation bottle is located in the positioning placement hole 506, the liquid level sensor 505 faces the oral fluid preservation bottle.

[0031] The working principle of the animal oral liquid sampling device for preventing and controlling animal diseases provided by the present invention is as follows: When it is necessary to sample the animal oral liquid, first rotate the bolt 406 so that the L-shaped groove plate 404 can rotate. Then rotate the L-shaped groove plate 404 to one side of the housing 401. Then pass the other end of the sampling tube 3 through the housing 401. Then reset the L-shaped groove plate 404 and screw the bolt 406 again. Select a suitable oral liquid storage bottle, and then place it on the positioning seat 507 directly below the positioning placement hole 506. Place the positioning frame 508 corresponding to the oral liquid storage bottle. Then insert the other end of the sampling tube 3 into the oral liquid storage bottle, and then place the oral liquid storage bottle into the positioning frame 508. Install the connector 2 at the top of the sampling rod 1. Specifically, align the positioning groove 203 with the positioning plate 103, and then move the connector 2 close to the sampling rod. When the limiting block 104 enters the limiting groove 204, as the connector 2 continues to move closer, at this time, the clamping block 105 contacts the inner wall of the limiting groove 204. The inner wall of the limiting groove 204 pushes the two clamping blocks 105 closer to each other, and the second spring is compressed. When the clamping block 105 is aligned with the hemispherical clamping groove 205, at this time, the clamping block 105 is clamped into the hemispherical clamping groove 205. Then clamp the sampling tube 3 into the arc-shaped clamping groove 108 on the connecting block 107. At this time, the fixing work of the connector 2, the sampling tube 3 and the sampling rod 1 is completed. Then, turn on the LED lamp bead 106, and use the sampling rod 1 to extend one end of the sampling tube 3 into the animal's oral cavity. By rotating the sampling rod 1, since one end of the sampling tube 3 is arc-shaped, one end of the sampling tube 3 can be placed in a more suitable oral liquid sampling area. After determining the position, push the sampling rod 1 so that the protective tube 604 contacts the animal's oral cavity, and then slowly push the sampling rod 1. Under the limiting action of the animal's oral cavity, the sampling tube 3 gradually extends out. Turn on the motor 407, and the motor 407 drives the extrusion head 403 to rotate. The extrusion head 403 repeatedly extrudes the sampling tube 3, generating negative pressure in the sampling tube 3, so as to extract the liquid in the animal's oral cavity through one end of the sampling tube 3 until the animal oral liquid flows into the oral liquid storage bottle. During this process, the liquid level sensor 505 can control the amount of animal oral liquid until the sampling is completed, and then the whole device can be reset according to the above process. When it is necessary to sample the oral liquid of multiple or multiple types of animals, by replacing the settings of the connector 2 and the sampling tube 3, the sampling process can be avoided from being contaminated, thereby improving the accuracy of sampling.

At the same time, the connector 2 and the sampling tube 3 are set as a whole, which can quickly replace the sampling tube 3, avoid sample contamination when sampling different numbers and different types of animals, and improve the sampling accuracy; through the peristaltic pump 4 composed of a housing 401, a mounting cavity 402, a pressing head 403, an L-shaped groove plate 404, a rotating shaft 405, a bolt 406 and a motor 407, it is convenient for the disassembly and assembly of the sampling tube 3, thus facilitating the replacement work of the sampling tube 3, and improving the sampling efficiency on the premise of better avoiding sample contamination; through the support frame 5 composed of a bottom plate 501, a support rod 502, a mounting plate 503, an adjusting frame 504, a liquid level sensor 505, a positioning placement hole 506, a positioning seat 507 and a positioning frame 508, it can fix the peristaltic pump 4, position and place it according to different oral fluid storage bottles, and automatically control the collection amount of oral fluid; through the anti-pollution mechanism 6 composed of a fixing ring 601, an outer sleeve 602, a spring 603 and a protection tube 604, when the sampling tube 3 is sent into the animal's oral cavity, it can avoid the sampling tube 3 contacting other objects before reaching the designated position in the animal's oral cavity, and can better avoid sample contamination.
