[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] After sampling, the end of the dropper of the existing device is easily contaminated by external dust, etc., thereby affecting the accuracy of the result.

[0021] In view of this, a pollution-proof food detection sampling device is provided. Through the cooperation between the baffle, the connecting rod and the first spring, the glass tube is closed after sampling, and the contact with the outside world is reduced when taking it out from the food solution. This solves the problem that the end of the dropper of the existing device is easily contaminated by external dust after sampling, thereby affecting the accuracy of the result.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: By Figure 1-3 It can be seen that an anti-pollution food detection sampling device includes a shell 1, a slide groove 7 is processed on the inner side of the shell 1, a slider 2 is slidably connected to the inner side of the slide groove 7, an opening is provided at the lower side of one side of the shell 1 for discharging liquid not remaining in the glass tube 3, the slider 2 can move inside the slide groove 7, the inner side of the slider 2 is movably connected to the glass tube 3, a rubber cap 6 is installed above the glass tube 3, and after the rubber cap 6 is squeezed flat and inserted into the liquid and released, the sampling of the glass tube 3 can be completed due to the air pressure principle, and a sealing mechanism is provided at the lower side of the shell 1, and the sealing mechanism includes a baffle 1 1. Connecting rod 14, block 13 and first spring 15. The top of baffle 11 is in contact with the bottom of housing 1 and the bottom of glass tube 3. A connecting rod 14 is fixed to one side of baffle 11. The top of connecting rod 14 is rotatably connected to block 13 fixed to the side of housing 1 through a pin. Connecting rod 14 can be rotated through the pin. The front pin of connecting rod 14 is provided with first spring 15. The device can drive baffle 11 to always be in contact with the bottom of housing 1 by elastic deformation of first spring 15. Both ends of first spring 15 are respectively fixedly connected to the front of connecting rod 14 and block 13.

[0024] In the specific implementation process, it is worth pointing out that the glass tube is sealed after sampling through the cooperation between the connecting rod 14, the block 13 and the first spring 15, which reduces the contact with the outside world when taking out the food solution, and solves the problem that the end of the dropper of the existing device is easily contaminated by external dust after sampling, thereby affecting the accuracy of the result;

[0025] Furthermore, a rubber plug 12 is installed below one side of the housing 1;

[0026] In the specific implementation process, it is worth pointing out that when the device is transported, the rubber plug 12 can be plugged into the opening at the lower side of the housing 1 to seal it and prevent impurities from entering the interior;

[0027] Furthermore, an annular plate 4 is mounted on the outside of the glass tube 3 and fits the top of the slider 2. The outer side of the annular plate 4 is threadedly connected to an outer ring 5 fixed on the top of the slider 2.

[0028] In the specific implementation process, it is worth noting that the user can rotate the glass tube 3 and the annular plate 4 fixed on the outer ring 5 to ensure stability;

[0029] Specifically, when using the anti-pollution food detection sampling device, the middle and lower part of the shell 1 is inserted into the food liquid to be sampled, the user can pinch the rubber cap 6 and press the slider 2 to drive the glass tube 3 to extend into the liquid, and then the glass tube 3 below first pushes the baffle 11 open, loosens the rubber cap 6, and due to the air pressure principle, a part of the liquid remains in the glass tube 3, and then lifts the shell 1 and pulls the slider 2 to reset. After lifting, since the first spring 15 is in a stretched state, it will quickly drive the baffle 11 to close the bottom of the shell 1 after the liquid surface is raised, and at the same time, the baffle 11 is attached to the bottom of the opening of the glass tube 3 to seal it, preventing the liquid collected by the glass tube 3 from flowing out and avoiding contamination with the outside world. At the same time, when the liquid surface is raised, the opening at the lower side of the shell 1 discharges the residual liquid in the shell 1. Then the user can transfer the shell 1 as a whole to the laboratory for detection, and there is no need to transfer it to a test tube for storage. When taking out the glass tube 3, rotate the annular plate 4 and pull it out upward.

[0030] Embodiment 2: By Figure 1 , 2 As can be seen from Figures 4 and 5, a straight rod 9 is fixedly connected to the bottom of the slider 2, and the outer side of the straight rod 9 is movably connected to a bottom plate 8 fixed to the side of the housing 1;

[0031] In the specific implementation process, it is worth pointing out that the straight rod 9 can limit the slider 2;

[0032] Furthermore, the outer side of the straight rod 9 is movably connected to a second spring 10, and the two ends of the second spring 10 are fixedly connected to the bottom of the slider 2 and the top of the bottom plate 8 respectively;

[0033] In the specific implementation process, it is worth pointing out that the device can drive the glass tube 3 to always be in a state where the bottom is in contact with the top of the baffle 11 by relying on the elastic deformation of the second spring 10, thereby achieving automatic reset;

[0034] Specifically, on the basis of the above-mentioned first embodiment, the automatic resetting of the dropper is achieved through the cooperation between the slide groove 7, the straight rod 9 and the second spring 10, and the user does not need to subsequently pull up the glass tube 3, which is convenient for operation.
