Description

Technical Field

[0001] This utility model belongs to the field of quantitative sampling technology, and in particular relates to a quantitative sampling device for liquid samples. Background Technology

[0002] During food sampling inspections, specific quality or volume requirements are set for the sample quantity due to the experimental requirements of the test items. For example, the sample quantity for edible vegetable oil repackaging is 1.5L for each test sample and the sample quantity for oil used in frying is 0.5L for each test sample and the sample quantity for reusable tableware is no less than 400mL.

[0003] When sampling liquid samples on-site, the lack of graduations on the sample bags makes it impossible to accurately quantify the sample volume. The sample bottles only have the total volume, which can only roughly estimate the sample volume, also making accurate quantification impossible. Furthermore, during sample transportation, collisions or high temperatures can cause leakage or deterioration of the liquid samples. All of these factors bring great inconvenience to the actual sampling of liquid samples. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a liquid sample quantitative sampling device, which uses a sample container with volume scale to hold a sealed bag for sampling, and can realize quantitative sampling of liquid samples, and provides effective protection for the sample during transportation through an external side protective layer.

[0005] Technical Solution: To achieve the above objectives, this utility model provides a liquid sample quantitative sampling device, comprising a sample container with a sealed bag internally fitted and laid out. The inner cavity of the sample container is a sample quantitative cavity, and a volume scale in the height direction is provided corresponding to the sample quantitative cavity. The sample container has a top opening and closing layer and a side protective layer. The top opening and closing layer is configured to open and close the sample quantitative cavity, and a sample inlet is provided on the top opening and closing layer. The opening of the sealed bag can enter and exit through the sample inlet.

[0006] Furthermore, the sample container has a square structure, and volume markings are provided at the height edges of the four sides of the square sample container.

[0007] Furthermore, the top opening and closing layer is the top layer of the sample container with a square structure, and the top opening and closing layer of the sample container is hinged to open and close.

[0008] Furthermore, a locking mechanism is provided between the top opening layer and the sample container.

[0009] Furthermore, the side protective layers are distributed on all four sides of the square sample container.

[0010] Furthermore, the side protective layer consists of a temperature control layer and a buffer layer from the inside out.

[0011] Furthermore, the temperature control layer is a refrigeration structure layer, and the buffer layer is a recoverable deformation structure layer.

[0012] Furthermore, a container cap is provided correspondingly for the sample inlet.

[0013] Beneficial effects: This utility model uses a sample container with volume scale to hold a sealed bag for sampling, which enables quantitative sampling of liquid samples. It also provides effective protection for samples during transportation through an external side protective layer, solving the problems of difficulty in quantitative sampling of liquid samples and low transportation safety.

[0015] Figure 2 This is an exploded view of the structure of this utility model. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, a liquid sample quantitative sampling device includes a sample container 1 with a sealed bag attached inside. The inner cavity of the sample container 1 is a sample quantitative chamber 10, and a volume scale 2 is provided in the height direction corresponding to the sample quantitative chamber 10. The sample container 1 has a top opening and closing layer 3 and a side protective layer 4. The top opening and closing layer 3 is configured to open and close the sample quantitative chamber 10, and a sample inlet 11 is provided on the top opening and closing layer 3. The opening of the sealed bag can enter and exit through the sample inlet 11. This utility model enables quantitative sampling of liquid samples by using a sample container 1 with volume scale 2 to hold a sealed bag for sampling. The external side protective layer 4 provides effective protection during sample transportation, solving the problems of difficulty in quantitative sampling of liquid samples and low transportation safety.

[0018] like Figure 1 and Figure 2 As shown, the sample container 1 has a square structure, and volume markings 2 are provided at all four height edges of the square sample container 1. The top opening and closing layer 3 is the top layer of the square sample container 1, and the top opening and closing layer 3 of the sample container 1 is hinged to open and close. A latch 5 is provided between the top opening and closing layer 3 and the sample container 1. A container cap 6 is provided correspondingly for the sample inlet 11. When sampling liquid samples on site, the steps are as follows:

[0019] First, open the top opening layer 3 of the sample container 1 and unscrew the container cap 6 of the sample inlet 11;

[0020] 2. Place a sealed bag in the sample container 1, lay the sealed bag flat, and then close the top opening and closing layer 3;

[0021] 3. Pass the opening of the sealed bag through the inlet 11, turn the bag over and fix the opening at the inlet 11;

[0022] IV. The liquid sample to be sampled is poured into the sealed bag through the sample inlet 11;

[0023] 5. At this point, volume scale 2 can be seen in any direction around sample container 1. Stop sampling after extracting the required volume of liquid sample.

[0024] 6. Seal the bag tightly;

[0025] 7. Open the top opening layer 3 again and put the tightly sealed bag opening into the sample container 1;

[0026] 8. Close the top opening and closing layer 3 again, lock the latch 5, and tighten the container cap 6 onto the sample inlet 11 to complete the sampling.

[0027] More specifically, the sample container 1, which has a square structure, has side protective layers 4 distributed on all four sides, thus providing good protection around the sample container 1. Furthermore, the side protective layers 4, from the inside out, consist of a temperature control layer 4.1 and a buffer layer 4.2. The temperature control layer 4.1 is a refrigeration structure layer, ensuring that the temperature of the sampled liquid is maintained within a suitable range during transportation. The refrigeration structure layer consists of an outer insulation layer with ice packs placed inside, and the opening of the outer insulation layer is sealed with an embedded cap 40. The buffer layer 4.2 is a resilient and deformable structure layer, ensuring that the sampled liquid is protected from impacts during transportation, preventing leakage and damage. The resilient and deformable structure layer can be a cushioning airbag or a cushioning rubber pad.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
