Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a sampling device for testing dairy products. Background Technology

[0002] Dairy products occupy an important place in people's daily diet, and their quality and safety have always been a major concern. With the continuous improvement of living standards, consumers have increasingly stringent requirements for dairy products, covering multiple aspects such as nutritional components and hygiene indicators. Accurate and scientific testing is crucial to ensuring the quality and safety of dairy products. Sampling is the first and extremely important step in the entire dairy product testing process. The representativeness and accuracy of the samples directly affect the reliability of subsequent test results and the scientific validity of the quality assessment of the entire batch of products.

[0003] For sampling liquid dairy products, the current common practice is to take samples from the top, middle, and bottom layers separately to ensure that the samples are sufficiently representative. In practice, operators use a syringe-like sampler, inserting it sequentially to different depths within the dairy product to extract samples. However, when sampling from the middle layer, the location of the sampler within the product relies on the operator's subjective judgment, making it difficult to guarantee that the sample obtained is from the middle layer. Therefore, this paper proposes a sampling device for dairy product testing. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems of the above-mentioned sampling device for dairy product testing, this utility model is proposed.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a sampling device for dairy product testing, comprising: a bottom tank and a piston cylinder, a middle tank and an upper tank being slidably arranged above the bottom tank, springs abutting between the bottom tank and the middle tank, and between the middle tank and the upper tank, the bottom of the piston cylinder being connected to the bottom tank, the middle tank and the upper tank via flexible hoses, a piston being slidably arranged inside the piston cylinder, a piston rod being slidably passed through the top of the piston cylinder and fixedly connected to the piston, and sampling ports being provided on the sides of the bottom tank, the middle tank and the upper tank;

[0007] When the upper tank is pressed, the two sets of springs compress synchronously, keeping the middle tank between the bottom tank and the upper tank.

[0008] In a preferred embodiment of the sampling device for dairy product testing described in this utility model, the middle tank and the upper tank are both annular, and the bottom of the piston cylinder is fixedly connected to an installation rod that slides through the middle tank and the upper tank, with the end of the installation rod fixedly connected to the bottom tank.

[0009] In a preferred embodiment of the sampling device for dairy product testing described in this utility model, a sleeve is slidably fitted on the mounting rod, the sleeve is fixedly connected to the top of the upper tank, and a threaded knob for limiting the relative sliding of the mounting rod and the sleeve is threaded through the sleeve.

[0010] In a preferred embodiment of the sampling device for dairy product testing described in this utility model, the mounting rod is rectangular, and the inner ring shapes of the middle tank and the upper tank match the mounting rod.

[0011] In a preferred embodiment of the sampling device for dairy product testing described in this utility model, a grip rod is fixedly connected to the top of the piston rod, and the grip rod is arranged perpendicular to the piston rod.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up a bottom tank, an upper tank, and two sets of springs, the middle tank can be kept in the middle position between the bottom tank and the upper tank. When sampling, simply press the upper tank onto the top layer of the dairy product, and the middle tank will automatically move to the middle layer of the dairy product. Compared with existing technologies, this solves the problem that the position of the sampler inside the dairy product can only be determined by the operator's subjective judgment, making it difficult to ensure accurate sampling of the middle layer of the dairy product.

[0014] 2. The device can simultaneously sample the bottom, middle, and top layers of dairy products by pulling the piston rod, using the bottom tank, middle tank, and top tank. Compared with existing technologies, it eliminates the need for multiple samplings and is easy to operate. Attached Figure Description

[0024] Reference Figures 1-3 This invention provides a sampling device for testing dairy products, comprising: a bottom tank 1 and a piston cylinder 5; a middle tank 2 and an upper tank 3 are slidably arranged above the bottom tank 1; springs 4 are abutting between the bottom tank 1 and the middle tank 2, and between the middle tank 2 and the upper tank 3; the bottom of the piston cylinder 5 is connected to the bottom tank 1, the middle tank 2, and the upper tank 3 via flexible hoses; a piston 7 is slidably arranged inside the piston cylinder 5; a piston rod 6 is slidably passed through the top of the piston cylinder 5 and fixedly connected to the piston 7; and sampling ports are provided on the sides of the bottom tank 1, the middle tank 2, and the upper tank 3.

[0025] Specifically, when the upper can 3 is pressed, the two sets of springs 4 are compressed synchronously to keep the middle can 2 between the bottom can 1 and the upper can 3. When in use, the device is inserted into the dairy product container until the bottom can 1 touches the bottom of the container. At this time, the bottom can 1 is located at the bottom layer of the dairy product. Pressing the upper can 3 will press the upper can 3 to the top layer of the dairy product. At this time, the middle can 2 is in the middle position between the bottom can 1 and the upper can 3, that is, the middle layer of the dairy product. By pulling the piston 7 up by the piston rod 6, the samples of the bottom, middle and upper layers can be drawn into the bottom can 1, the middle can 2 and the upper can 3 respectively.

[0026] like Figure 1 and Figure 2 As shown, both the middle tank 2 and the upper tank 3 are annular. The bottom of the piston cylinder 5 is fixedly connected to the mounting rod 8, which slides through the middle tank 2 and the upper tank 3. The end of the mounting rod 8 is fixedly connected to the bottom tank 1.

[0027] like Figure 1 and Figure 2 As shown, a sleeve 9 is slidably sleeved on the mounting rod 8. The sleeve 9 is fixedly connected to the top of the upper tank 3. A threaded knob 10 is threaded through the sleeve 9 to limit the relative sliding of the mounting rod 8 and the sleeve 9. The threaded knob 10 is used to fix the position of the upper tank 3, thereby maintaining the positions of the bottom tank 1, the middle tank 2 and the upper tank 3, which is convenient for sampling.

[0028] Specifically, the mounting rod 8 is rectangular, and the inner ring shape of the middle tank 2 and the upper tank 3 matches the mounting rod 8. Here, the shape of the mounting rod 8 can restrict the rotation of the middle tank 2 and the upper tank 3, thereby improving the stability of the device structure.

[0029] like Figure 1 As shown, a grip 11 is fixedly connected to the top of the piston rod 6. The grip 11 is set perpendicular to the piston rod 6. By setting the grip 11 perpendicular to the piston rod 6, it is convenient to pull the piston rod 6 upward.

[0030] Working principle: Insert the device into the dairy product container until the bottom tank 1 touches the bottom of the container. At this time, the bottom tank 1 is located in the lower layer of the dairy product. Press the upper tank 3 through the sleeve 9. After pressing the upper tank 3 to the upper layer of the dairy product, tighten the threaded knob 10. At this time, the position of the upper tank 3 is fixed in the upper layer of the dairy product. The middle tank 2 is located in the middle position between the bottom tank 1 and the upper tank 3, that is, the middle layer of the dairy product.

[0031] During sampling, the piston rod 6 is pulled up, which drives the piston 7 to move upward, thereby drawing samples from the lower, middle, and upper layers of the dairy products into the bottom tank 1, middle tank 2, and upper tank 3, respectively.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
