[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This embodiment provides a food testing sampler, the structural diagram of which is as follows: Figures 1-4As shown, it includes a sampling bottle 1, a bottle cap 2 is provided on the top of the sampling bottle 1, and an air suction component 3 for extracting the air in the sampling bottle 1 is provided on the bottle cap 2. The bottle cap 2 is also provided with an external threaded ring seat 13 for connecting the inside and outside of the sampling bottle 1, and a connecting cap 5 is connected to the external threaded ring seat 13. The two end surfaces of the connecting cap 5 are respectively provided with a first thread groove 14 and a second thread groove 19, and the first thread groove 14 and the second thread groove 19 are both threadedly matched with the external threaded ring seat 13. A sampling hose 7 that is connected to the first thread groove 14 and can pass through the external threaded ring seat 13 and extend into the sampling bottle 1 is connected in the second thread groove 19. A sealing film 15 for sealing the first thread groove 14 is provided on the end surface of the connecting cap 5 with the first thread groove 14, and the sealing film 15 can be pierced by the external threaded ring seat 13 Through this structural method, when the connecting cap 5 is threadedly connected to the external threaded ring seat 13 using the second thread groove 19, the sampling hose 7 can pass through the external threaded ring seat 13 and be placed in the sampling bottle 1, and the sealing film 15 blocks the first threaded groove 14, blocking the air circulation inside and outside the sampling bottle 1, effectively preventing the sampling hose 7 and the inside of the sampling bottle 1 from being contaminated by the external environment during the storage and carrying of the sampler. When the connecting cap 5 is threadedly connected to the external threaded ring seat 13 using the first thread groove 14, the external threaded ring seat 13 pierces the sealing film 15, and the sampling hose 7 is located outside the sampling bottle 1 and is connected to the inside of the sampling bottle 1. The sampling hose 7 is extended into the liquid food, and the air in the sampling bottle 1 is exhausted by the suction component 3, so that the liquid food can be sucked into the sampling bottle 1 to achieve food sampling.

[0024] As a preferred technical solution in this embodiment, a connecting tube 16 is provided within the externally threaded ring seat 13. The connecting tube 16 is in communication with the first thread groove 14. One end of the sampling hose 7 is sleeved onto the connecting tube 16, facilitating assembly and replacement of the sampling hose 7. A ridge 20 is provided on the outer surface of the connecting tube 16, allowing the sampling hose 7 to be tightly sleeved onto the connecting tube 16. A counterweight block 8 is fixedly sleeved on the end of the sampling hose 7 away from the connecting tube 16. The counterweight block 8 can pass through the externally threaded ring seat 13. During the sampling process, the provision of the counterweight block 8 facilitates the sampling hose 7 to sink to the bottom of the liquid food container for sampling, thereby improving the sampling effect.

[0025] Furthermore, in this embodiment, a first sealing gasket 17 is provided on the inner end surface of the first thread groove 14, and a second sealing gasket 18 is provided on the inner end surface of the second thread groove 19, which are used for sealing when the connecting cap 5 is threadedly sleeved with the external thread ring seat 13; the sampling bottle 1 is set to be transparent, and a capacity scale 4 is engraved on the side wall of the sampling bottle 1 to facilitate observation of the sampling volume.

[0026] As a preferred technical solution in this embodiment, the suction component 3 includes an suction hose 9 arranged through the bottle cap 2 and a rubber suction ball 10 connected to the end of the suction hose 9 located outside the bottle cap 2. A partition plate 6 is fixed on the inner wall of the bottle cap 2. The partition plate 6 is located between the external threaded ring seat 13 and the suction hose 9, and is used to separate the external threaded ring seat 13 and the end of the suction hose 9 connected to the bottle cap 2, so as to prevent the sample in the sampling bottle 1 from entering the suction hose 9 and causing contamination to the suction hose 9 and the rubber suction ball 10. The end of the rubber suction ball 10 connected to the suction hose 9 and the end away from the suction hose 9 are respectively provided with a first check valve 11 and a second check valve 12. During the sampling process, the rubber suction ball 10 is squeezed by hand, the first check valve 11 is closed, and the second check valve 12 is opened. The air inside the rubber suction ball 10 is discharged from the second check valve 12. After the rubber suction ball 10 is released, the elastic force of the rubber suction ball 10 is restored, the second check valve 12 is closed, and the first check valve 11 is opened. The air in the sampling bottle 1 is sucked into the rubber suction ball 10, and negative pressure is generated in the sampling bottle 1, so that the liquid food can be sucked into the sampling bottle 1 from the sampling hose 7 to achieve sampling.

[0027] Working principle: When the food testing sampler is stored, the sampling hose 7 and the counterweight block 8 pass through the external threaded ring seat 13 and are placed in the sampling bottle 1. The connecting cap 5 is spirally connected to the external threaded ring seat 13 using the second threaded groove 19. The external threaded ring seat 13 and the second sealing gasket 18 in the second threaded groove 19 are abutted and sealed. At this time, the sealing film 15 blocks the first threaded groove 14 to block the air circulation inside and outside the sampling bottle 1. The sampling hose 7 is placed in the sampling bottle 1, which can effectively prevent the sampling hose 7 and the inside of the sampling bottle 1 from being contaminated by the external environment during the storage and carrying of the sampler. Phenomenon, when sampling with a sampler for food testing, unscrew the connecting cap 5 to disengage it from the external threaded ring seat 13, pull the sampling hose 7 out of the sampling bottle 1, then turn the connecting cap 5 upside down, use the external threaded ring seat 13 to pierce the sealing film 15, and the connecting cap 5 is threadedly connected to the external threaded ring seat 13 using the first thread groove 14. Thus, the sampling hose 7 is located outside the sampling bottle 1 and is connected to the inside of the sampling bottle 1. Insert one end of the sampling hose 7 with the counterweight block 8 into the liquid food, hold the rubber suction ball 10 in your hand and squeeze it repeatedly to suck the liquid food into the sampling bottle 1, thereby realizing food sampling.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
