Description

Technical Field

[0001] The utility model relates to the field of food detection samplers, in particular to a fast sampler for food detection. Background Art

[0002] Food testing instruments are used to detect harmful substances in food samples, such as heavy metals, pesticide residues, veterinary drug residues, pathogenic bacteria, toxins, etc., to ensure food safety by quickly and accurately detecting potential harmful substances in food. When sampling and testing liquid foods on the market, the siphon method is generally used for liquid foods or semi-fluid foods stored in containers such as barrels, cylinders, and cans.

[0003] The problems with the prior art are as follows: the data of each layer of liquid food will be different due to the fermentation effect or processing method. When the liquid food under the prior art is sampled by the siphon method, it is easy to mix the liquid food samples of different layers. If the samples are mixed, it will affect the test data and there is a risk of detection errors, which is not conducive to ensuring food safety.

[0004] Therefore, we propose a rapid sampler for food testing to solve the above problems. Utility Model Content

[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] like Figure 1 As shown, the utility model provides a rapid sampler for food testing, including an upper tube 1 for connection and installation. A tube sleeve 2 is provided on the front end of the surface of the upper tube 1. The tube sleeve 2 can be used to make the connection with the outside of the test sample more stable when collecting samples, which is convenient for collection. A connecting hole 3 is provided at the rear end of the upper tube 1 for connecting to a lower tube 4.

[0025] like Figure 2 , 3 As shown in Figures 5 and 6, the lower tube 4 of the utility model is used to extend into the sample for collection. The lower tube 4 is connected to the upper tube 1 through the connecting hole 3. The lower tube 4 includes a tube body 41, a thread 42, a cone head 43, a baffle 44 and a piston structure 45. The surface of the tube body 41 is provided with a thread 42. The tube body 41 is used for connection and installation, and is also used as a container for collecting samples, and is connected to the upper tube 1 through the thread 42. The front end of the tube body 41 is provided with a cone head 43, which can be used to more easily extend into the sample, and the bottom is provided with a baffle 44 for connection and installation, and at the same time prevents the piston structure 45 from passing through the baffle 44 and being installed in the tube body 41. The baffle 44 is used to prevent the sample collected by the tube body 41 from leaking;

[0026] The threads 42 provided on the pipe body 41 are distributed on its surface in a circular array, and the threads 42 are threadedly connected with the internal threads 1A provided inside the upper pipe tube 1. The threaded connection can be more tightly connected. This connection method can control the required collection depth, making it convenient for the staff to collect data.

[0027] Among them, a feed hole 43A is installed obliquely on the cone head 43; and in the present embodiment, three feed holes 43A are provided, and a circular array is installed on the head 43. By providing the feed holes 43A, the sample can be sucked into the tube body 41, and the oblique penetration installation can effectively prevent the sample from mixing into the tube body 41.

[0028] like Figure 4 As shown, the plug structure 45 of the utility model includes a handle 451, a connecting plate 452, a piston rod 453 and a piston 454. The handle 451 is connected to the baffle 44 through the connecting plate 452. The front end of the handle 451 passes through the connecting plate 452 and is connected to the baffle 44 and the piston rod 453. The piston rod 453 can be pulled or pushed to move in the tube body 41 through the handle 451 to generate negative pressure. The front end of the piston rod 453 is provided with a piston 454. When the piston 454 is pulled, air can be inhaled or discharged, thereby achieving the purpose of inhaling or discharging the sample. The piston rod 453 and the piston 454 are both installed in the tube body 41.

[0029] The piston 454 is a trapezoidal shape with a larger front and a smaller rear, and the front end is tightly fitted with the inner wall of the tube body 41. The trapezoidal design with a larger front and a smaller rear can prevent air leakage and prevent the exhaust or suction effect from being deteriorated due to air leakage.

[0030] The piston rod 453 is a cylindrical structure, and the cylindrical structure design can better push the piston 454 to move in the tube body 41.

[0031] Working principle:

[0032] First, fix the upper tube 1 on the surface of the sample to be collected through the tube sleeve 2. The upper tube 1 is provided with a connecting hole 3 at the tail end for connecting with the lower tube 4. The thread 42 on the surface of the lower tube 4 is matched with the internal thread 1A provided inside the upper tube 1, so that the lower tube 4 is screwed into a suitable position, and the piston structure 45 in the lower tube 4 is pulled to collect the sample;

[0033] The lower tube 4 includes a tube body 41, which can be screwed into a suitable position of the upper tube 1 through the spiral on the tube body 41. The cone head 43 at the front end of the tube body 41 can better penetrate into the sample. By pulling the piston structure 45, negative pressure can be generated in the tube body 41, and the sample to be collected is sucked into the tube body 41 through the feed hole 43A to complete the collection. The baffle 44 can prevent the sample collected by the tube body 41 from leaking. When collecting, the sample can be discharged by simply pushing the piston structure 45;

[0034] The piston structure 45 includes a handle 451, a connecting plate 452, a piston rod 453 and a piston 454. The connecting plate 452 is used for connection and installation. Pulling or pushing the handle 451 will cause the piston 454 to slide in the tube body 41 driven by the piston rod 453 to collect or discharge the sample.

[0035] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
