[0002] Dairy products refer to various foods made from cow's milk or goat's milk and their processed products as the main raw materials, with or without appropriate amounts of vitamins, minerals and other auxiliary materials, under the conditions required by laws, regulations and standards. They are also called cream products. The sample liquid extraction device for dairy product testing is a device used for dairy product testing. Its main function is to extract samples from dairy products for testing.

[0003] In the prior art, a Chinese patent document with publication number CN218297690U proposes a sample liquid extraction device for dairy product detection, which achieves the purpose of heating the dairy product inside the suction cylinder through the cooperation of the suction cylinder and the heater, and achieves the effect of avoiding subsequent heating and cooling. Through the cooperation of the sample bottle and the sealing disk, the heated dairy product flows into the sample bottle, avoiding the contact of the dairy product with the external environment, and achieving the effect of avoiding the external environment from affecting the detection structure of the dairy product, thereby solving the problem that common sampling is easy to be in continuous contact with the external environment and is not easy to heat. However, the dairy solution will be stratified after being placed for a period of time, and it needs to be stirred before extraction and sampling to improve the accuracy of the detection result. The above patent document is consistent with the prior art in that no stirring structure is provided, and manual stirring is required before sampling, and the stirring cannot be carried out simultaneously with the extraction work, thereby greatly reducing the extraction work efficiency. Further, we disclose a sample liquid extraction device for dairy product detection to meet the actual demand that the existing dairy product extraction device is not provided with a stirring structure and cannot be linked with the extraction work, resulting in low work efficiency.

[0005] Based on the above-mentioned purpose, the utility model provides a sample liquid extraction device for dairy product testing, comprising an extraction cylinder for accommodating dairy product sample liquid, the interior of the extraction cylinder is vertically slidably connected with a push rod for extracting the dairy product sample liquid, the outer side of the extraction cylinder is provided with a stirring assembly that is linked to the sliding of the push rod, the stirring assembly is composed of a plurality of vertically arranged stirring rods, and the outer wall of the extraction cylinder is fixedly connected to a protective cover near the upper end to prevent dust from entering the dairy product bottle.

[0006] Preferably, the upper ends of the plurality of stirring rods are fixedly connected with a spiral guide rod, the middle of the spiral guide rod is sleeved with a transmission block, the middle of the transmission block is provided with an annular groove, and the transmission block is sleeved on the spiral guide rod through the annular groove in the middle.

[0007] Preferably, rectangular grooves are evenly spaced apart in the middle of the extraction cylinder near the upper end, a connecting rod is arranged inside the rectangular groove, and both ends of the connecting rod are fixedly connected to the transmission block and the push rod respectively.

[0008] Preferably, the side wall of the shield is made of rubber material, and the inner wall of the shield is evenly spaced to form a plurality of grooves for fitting with the mouth of a dairy product bottle.

[0009] Preferably, a limit block for limiting the rising height of the piston is fixedly connected to the upper end of the rectangular groove inside the extraction cylinder, and the length of the piston is greater than the length of the rectangular groove.

[0010] Preferably, the upper ends of the plurality of spiral guide rods are rotatably connected to the shield via bearings.

[0011] The beneficial effects of the utility model are as follows: when the extraction device extracts dairy products, first the lower end of the extraction cylinder and the stirring rod are placed in a dairy product container, a protective cover is set on the upper end of the container to prevent air from entering the container, and the push rod is pulled by the pull plate at the rear end of the push rod to move the push rod upward. The upward movement of the push rod drives the outer transmission block to move upward through the connecting rod, and then the spiral guide rail can be driven to rotate, thereby causing the stirring rod to rotate, stirring the emulsification bottle solution, improving the accuracy of the later detection results, and while stirring, the piston can also rise due to the rise of the pull rod to complete the extraction of the internal dairy solution. Through this structural design, the stirring of the internal dairy sample liquid can be completed during the extraction work, so that the two are linked, which greatly improves the working efficiency of using the device to extract dairy products.
