Description

Technical Field

[0001] The utility model relates to the technical field of food safety detection, in particular to a sampling device for food safety detection. Background Art

[0002] Food safety means that food is non-toxic and harmless, meets the proper nutritional requirements, and does not cause any acute, subacute or chronic harm to human health. Food safety is also an interdisciplinary field that specifically explores how to ensure food hygiene and food safety during food processing, storage, and sales, reduce disease risks, and prevent food poisoning. Samplers are required for testing liquid foods.

[0003] The existing patent CN216847049U sampling device, the sampling device for food safety detection, has a simple structure and is easy to operate. By arranging a sampling outer tube and a sampling inner tube at the lower end of the sampling body, and arranging the sampling inner tube inside the sampling outer tube, and adjusting the position of the sampling inner tube in the sampling outer tube according to the depth of liquid food detection sampling, by adjusting the length between the sampling outer tube and the sampling inner tube, the sampling depth is adjusted to avoid the user being unable or inconvenient to sample liquid foods of different depths. The device is convenient for users to sample liquid foods of different depths, thereby improving the safety of liquid foods;

[0004] The above technical solution only improves the sampling tube, but since there will be a certain time difference between sampling and testing, testing the food at an interval after sampling will affect the freshness of the food during testing. At the same time, the samples cannot be effectively preserved during transportation, which reduces the accuracy of the food testing data. Therefore, the utility model proposes a sampling device for food safety testing. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art and to provide a sampling device for food safety detection.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sampling device for food safety detection, comprising a sampler body, the sampler body comprising a sampling tube, a sampling assembly is arranged on one side of the sampling tube, a pump head is slidably connected to the other side of the sampling tube, a connecting seat is arranged at the bottom of the sampling tube, a sleeve is arranged at the bottom of the connecting seat, and a storage assembly is slidably connected inside the sleeve;

[0007] The storage assembly includes a storage bottle, which is provided with storage cavities in sequence from top to bottom, and there are three storage cavities in total. A rubber plug is embedded and installed on one side of the three storage cavities on the storage bottle, and an exhaust valve is fixedly connected to the other side of the three storage cavities on the storage bottle.

[0008] As a preferred embodiment, the sampling assembly includes a sampling sleeve, which is fixedly connected to the sampling tube. The other end of the sampling sleeve is threadedly connected to the sampling tube. An adjustment plate is provided on the sampling tube. There are two adjustment plates in total, and the two adjustment plates are symmetrical to the center of the sampling tube.

[0009] The beneficial effect of adopting the above further scheme is: through the setting of the sampling component, the sampling tube can be rotated by the adjustment plate as needed when the device is performing sampling work, so that the distance between the sampling tube and the sampling sleeve is increased or decreased, thereby sampling liquids at different depths, thereby improving the use range of the device.

[0010] As a preferred embodiment, the bottom of the sampling tube is fixedly connected with a liquid outlet pipe, the liquid outlet pipe is fixedly connected with a connecting pipe, the other end of the connecting pipe is fixedly connected with a tapered plug, and the tapered plug is a tapered structure.

[0011] The beneficial effect of adopting the above further scheme is: the liquid extracted from the sampling component is introduced into the storage component through the sampling tube through the connecting tube for storage, and further, through the conical structure design of the conical plug, the connecting tube can be more conveniently inserted into the rubber stopper through the conical plug.

[0012] As a preferred embodiment, the top of the sampling tube is fixedly connected to a water inlet pipe, and a cleaning cylinder is provided on the water inlet pipe.

[0013] The beneficial effect of adopting the above-mentioned further scheme is: through the design of the cleaning cylinder, when the device is used to sample multiple samples, the cleaning liquid in the cleaning cylinder can be pumped into the sampling tube through the water inlet pipe through the pump head, and the inner wall of the sampling tube, the connecting tube and the sampling component can be flushed, thereby avoiding the problem of inaccurate detection data caused by sample residues when sampling multiple times.

[0014] As a preferred embodiment, a limit seat is threadedly connected to the sleeve below the storage assembly, the diameter of the storage assembly is smaller than the inner wall diameter of the sleeve, and the diameter of the limit seat is matched with the diameter of the sleeve.

[0015] The beneficial effect of adopting the above further scheme is: the storage component is limited by the threaded connection between the limit seat and the sleeve. Since the storage component is designed to be slidably connected in the sleeve, the storage component can be replaced more conveniently. Therefore, the limit seat is required to limit the storage component to prevent the storage component from slipping out of the sleeve during the sampling process.

[0016] As a preferred implementation, the diameter of the pump head is matched with the inner wall diameter of the sampling tube, and a pull rod is provided on the side of the pump head away from the sampling assembly.

[0017] The beneficial effect of adopting the above further scheme is: the pump head is driven to move back and forth in the sampling tube by the pull rod. At this time, under the action of the pump head, extraction can be carried out through the sampling tube, sampling operation can be carried out by pulling the pull rod, or cleaning operation can be carried out by pushing the pull rod.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, through the design of the storage component, not only can multiple sampling be carried out during sampling to ensure the accuracy of the sampling data, but the samples can also be sealed and preserved through the storage component to avoid contamination during sample transportation. When sampling, the connecting tube is inserted into one of the rubber plugs under the action of the conical plug. At this time, the conical plug penetrates the rubber plug, and the pump head is driven to move in the sampling tube by pulling the pull rod, and the sample is pumped into the storage chamber for storage, and the original gas in the storage chamber is further discharged through the exhaust valve. After the sampling is completed, the conical plug is pulled out, and the jack is squeezed and sealed under the action of the rubber material of the rubber plug to prevent the sample from leaking.

[0020] 2. In the utility model, since the storage component can store multiple samples, a cleaning device is required to clean the inside of the sampler body to avoid inaccurate detection data caused by the residue of multiple samples. After the sampling is completed, continue to pull the pull rod until the pump head moves to one side of the water inlet pipe. At this time, the liquid in the cleaning cylinder flows into the interior of the sampling tube through the water inlet pipe to flush the sampling tube, the connecting tube and the sampling component. The pump head is further pushed by the pull rod to accelerate the circulation of the liquid in the sampling tube, thereby further improving the flushing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] 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.

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: a sampling device for food safety detection, comprising a sampler body 1, the sampler body 1 comprises a sampling tube 2, a sampling assembly 3 is arranged on one side of the sampling tube 2, a pump head 23 is slidably connected to the other side of the sampling tube 2, a connecting seat 25 is arranged at the bottom of the sampling tube 2, a sleeve 26 is arranged at the bottom of the connecting seat 25, a storage assembly 6 is slidably connected inside the sleeve 26; the storage assembly 6 comprises a storage bottle 61, the storage bottle 61 is provided with storage cavities 62 in sequence from top to bottom, and there are three storage cavities 62 in total, a rubber plug 63 is embedded and installed on one side of the three storage cavities 62 of the storage bottle 61, an exhaust valve 64 is fixedly connected to the other side of the three storage cavities 62 of the storage bottle 61, the diameter of the pump head 23 is adapted to the inner wall diameter of the sampling tube 2, and a side of the pump head 23 away from the sampling assembly 3 is provided with The pull rod 24 and the top of the sampling tube 2 are fixedly connected to the water inlet pipe 22, and the water inlet pipe 22 is provided with a cleaning cylinder 4. Through the design of the storage component 6, not only can multiple sampling be carried out during sampling to ensure the accuracy of the sampling data, but the sample can also be sealed and preserved through the storage component 6 to avoid contamination during sample transportation. When sampling, the connecting tube 5 is inserted into one of the rubber plugs 63 under the action of the conical plug 51. At this time, the conical plug 51 penetrates the rubber plug 63, and the pump head 23 is driven to move in the sampling tube 2 by pulling the pull rod 24, and the sample is pumped into the storage chamber 62 for storage, and the original gas in the storage chamber 62 is further discharged through the exhaust valve 64. After the sampling is completed, the conical plug 51 is pulled out, and the jack is squeezed and sealed under the action of the rubber material of the rubber plug 63, which solves the technical problem of sealed storage of multiple samples.

[0029] Further, such as Figure 2 - Figure 3As shown: the sampling component 3 includes a sampling sleeve 31, which is fixedly connected to the sampling tube 2. The other end of the sampling sleeve 31 is threadedly connected to the sampling tube 32. An adjustment plate 33 is arranged on the sampling tube 32. There are two adjustment plates 33 in total, and the two adjustment plates 33 are symmetrical to the center of the sampling tube 32. Through the arrangement of the sampling component 3, the sampling tube 32 can be rotated by the adjustment plate 33 as needed during the sampling work, so that the distance between the sampling tube 32 and the sampling sleeve 31 is increased or decreased, which solves the technical problem of effective sampling in sampling environments at different depths.

[0030] The above solution still has the problem that the connecting pipe 5 cannot effectively pass through the rubber plug 63. Figure 2 As shown: the bottom of the sampling tube 2 is fixedly connected to a liquid outlet pipe 21, the liquid outlet pipe 21 is fixedly connected to a connecting pipe 5, the other end of the connecting pipe 5 is fixedly connected to a tapered plug 51, the tapered plug 51 is a tapered structure, and the liquid extracted from the sampling component 3 is introduced into the storage component 6 through the sampling tube 2 through the connecting pipe 5 for storage, and further, through the tapered structure design of the tapered plug 51, the connecting pipe 5 can be more conveniently inserted into the rubber stopper 63 through the tapered plug 51.

[0031] The above solution also has the problem that the storage component 6 is easily separated from the sleeve 26 during the sampling process due to the sliding design of the storage component 6 and the sleeve 26. Figure 2 As shown: In the present embodiment, a limit seat 27 is threadedly connected to the sleeve 26 below the storage component 6. The diameter of the storage component 6 is smaller than the inner wall diameter of the sleeve 26. The diameter of the limit seat 27 is matched with the diameter of the sleeve 26. The storage component 6 is limited by the threaded connection between the limit seat 27 and the sleeve 26. Since the storage component 6 is slidably connected in the sleeve 26, the storage component 6 can be replaced more conveniently. Therefore, the limit seat 27 is required to limit the storage component 6 to prevent the storage component 6 from slipping out of the sleeve 26 during the sampling process.

[0032] Working principle:

[0033] like Figure 1-4As shown, firstly, the sampling tube 32 is rotated by adjusting the plate 33 to adjust the sampling tube 32 to a suitable position to facilitate subsequent sampling work, clean water is injected into the cleaning cylinder 4 and then fixed on the water inlet pipe 22, and the storage component 6 is further inserted into the sleeve 26, and the limit seat 27 is threadedly connected with the bottom of the sleeve 26 to limit the storage component 6, and the connecting pipe 5 is inserted into one of the rubber plugs 63 through the tapered plug 51. After the preparation is completed, the sampling component 3 is aligned with the sampling source, and the pull rod 24 is pulled to drive the pump head 23 to move, and the sample is drawn into the sampling tube 2 after passing through the sampling component 3. At this time, the sample in the sampling tube 2 passes through the connecting tube 5 and enters the storage chamber 62 for storage. It should be noted that when pulling the pull rod 24, the pump head 23 cannot exceed the position of the water inlet pipe 22. After the sampling is completed, the conical plug 51 is pulled out, and the pull rod 24 is continued to be pulled until the pump head 23 moves to one side of the water inlet pipe 22. At this time, the liquid in the cleaning cylinder 4 flows into the interior of the sampling tube 2 through the water inlet pipe 22 to rinse the sampling tube 2, the connecting tube 5 and the sampling assembly 3. Using the above method, the conical plug 51 is inserted into the other rubber stopper 63 to extract the second sample.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
