[0002] Liquid food refers to food in liquid form, usually including various beverages and soups. Common liquid foods include: beverages, such as water, juice, milk, etc.; soups, such as broth, vegetable soup, etc.; liquid food products, such as milkshakes, sauces, etc. The advantages of the liquid foods we usually eat include easy digestion and fast absorption, which are suitable for all kinds of people, especially patients or people in recovery. Since liquid food is in a liquid and flowing state, it needs to be canned and sealed for preservation. In factories specializing in liquid food processing, before the liquid food produced by liquid is put on the market, it is necessary to sample and inspect the food produced by it to ensure the quality of the food. In the process of sampling and testing liquid food, the current method is: before canning, the liquid food is put in a container, and then it is sealed and sent to the quality department for testing; this sampling and testing method is easy to spill during the sampling process, and even cause liquid food contamination, affecting the test results.

[0021] In order to make the purpose, technical solutions and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figures 1 to 4 As shown, a food detection sampling device is used to sample and collect liquid food that needs to be sampled and tested. The sampling device can quickly collect and sample the liquid food that needs to be tested, thereby saving time. The sampling device is inspired by a "syringe", and the sampling device includes a sampling collection tube 1, one end of the sampling collection tube 1 is connected with a sampling needle 11, the sampling needle 11 is used to connect with one end of a sampling telescopic hose, and the other end of the sampling telescopic hose is placed in the liquid food that needs to be sampled; a sampling sliding piston 2 is arranged in the hollow cavity of the sampling collection tube 1, the sampling sliding piston 2 is in close contact with the inner wall of the hollow cavity of the sampling collection tube 1 and is movably adapted, the end of the sampling sliding piston 2 away from the sampling needle 11 is connected to a piston connecting rod 21, and the other end of the piston connecting rod 21 is rotatably and detachably connected to a movable rod 3 through a bearing, the other end of the movable rod 3 can movably pass through a sampling collection cover 4 and is connected to a connecting structure for driving the movable rod 3 to move along the hollow cavity of the sampling collection tube 1, and the sampling collection cover 4 is threadedly and detachably connected to the end of the sampling collection tube 1 away from the sampling needle 11.

[0024] In the embodiment, the sampling needle 11 of the sampling device is connected to one end of the sampling hose, and the other end of the sampling hose is placed in the liquid food that needs to be sampled and tested, and then the movable rod 3 is driven to move along the inner wall of the hollow cavity of the sampling collection tube 1 by controlling the connection structure, thereby driving the sampling sliding piston 2 to "slide in close contact" (similar to a piston) along the inner wall of the hollow cavity of the sampling collection tube 1, and then through "pressure", the liquid food that needs to be sampled is sucked into the sampling collection tube 1 through the sampling hose, and after the sampling is completed, the sampling needle 11 is temporarily blocked to avoid contamination during the sampling process and affect the accuracy of the test results.

[0025] Example 2

[0026] On the basis of Example 1, the connection structure of the arrangement includes a movable rotating sleeve 5; one end of the movable rotating sleeve 5 is rotatably connected to the sampling collection cover 4 through a bearing, and the end of the movable rod 3 away from the sampling needle 11 passes through the hollow cavity of the movable rotating sleeve 5 and is rotatably arranged with the movable rotating sleeve 5. At the same time, a rotating connector is arranged in the hollow cavity of the end of the movable rotating sleeve 5 away from the sampling collection cover 4; the end of the movable rod 3 away from the sampling needle 11 passes through the rotating connector and the movable rod 3 is threadedly connected to the rotating connector; the end of the movable rod 3 away from the sampling needle 11 is connected to a plug cap for moving the movable rod 3 out of the rotating connector.

[0027] In the embodiment, by rotating the movable rotating sleeve 5, the movable rotating sleeve 5 drives the rotating connector to rotate together, and then the movable rod 3 is driven to rotate by the rotating connector through a threaded connection. Because the movable rod 3 is movable (it can also be a threaded connection) through the sampling and collecting cover 4, the movable rod 3 is driven to move relatively along the hollow cavity of the sampling and collecting tube 1, and then the sampling sliding piston 2 is driven to "slide in close contact" along the inner wall of the hollow cavity of the sampling and collecting tube 1. Through "pressure", the liquid food to be sampled is sucked into the sampling and collecting tube 1 through the sampling hose to complete the sampling.

[0028] It should be noted here that the liquid food to be sampled is temporarily placed in the sampling collection tube 1 of the sampling device. During this process, the sampled liquid food is not allowed to contact the outside world. After the sampling is completed, the sampling needle 11 is temporarily blocked. During the entire sampling process, the sampled liquid food is not allowed to contact the outside world, thereby avoiding contact with the outside air during the sampling process, which may cause contamination of the sampled liquid food.

[0029] In addition, in the embodiment, if the movable rod 3 is connected to the sampling and collecting cover 4 by a threaded connection, the movable rod 3 can be rotated directly, and then the sampling sliding piston 2 is driven by the movable rod 3 to "slide in close contact" along the inner wall of the hollow cavity of the sampling and collecting tube 1. Through "pressure", the liquid food to be sampled is sucked into the sampling and collecting tube 1 through the sampling hose, and sampling can also be completed.

[0030] Example 3

[0031] The movable rotating sleeve 5 of the arrangement is provided with an elastic protective sliding sleeve 31, which can be slidably sleeved on the movable rod 3 and arranged between the rotating connector and the sampling and collecting cover 4; one end of the elastic protective sliding sleeve 31 is used for contacting with the rotating connector, and the other end of the elastic protective sliding sleeve 31 is elastically contacted with the sampling and collecting cover 4 through an elastic member. In addition, the elastic member of the arrangement includes a protective spring 32; the protective spring 32 is sleeved on the movable rod 3 and arranged between the elastic protective sliding sleeve 31 and the sampling and collecting cover 4, one end of the protective spring 32 is connected to the elastic protective sliding sleeve 31, and the other end of the protective spring 32 is connected to the sampling and collecting cover 4 (it may not be connected to the sampling and collecting cover 4, and a contact setting is also possible).

[0032] In the embodiment, when the movable rotating sleeve 5 is rotated, the elastic protective sliding sleeve 31 and the protective spring 32 can protect the movable rotating sleeve 5 and the movable rod 3 during the movement, thereby increasing the service life.

[0033] In this regard, the entire sampling device can not only quickly collect and sample liquid food to save time, but also avoid the possibility of spillage and contamination during the sampling process, thereby ensuring the accuracy of the test results of the liquid food sampled and tested.
