Description

Technical Field

[0001] The utility model relates to the technical field of food detection sampling boxes, in particular to a constant temperature sampling box. Background Art

[0002] During the food detection sampling process, for frozen foods, sterilized tools are required for sampling, and the samples must be kept frozen at all times before being delivered to the laboratory. This is because if the samples melt due to excessive temperature, it will affect the quality and safety assessment accuracy of the food. The existing solution is to use a refrigerated box to prevent the samples from melting. However, after the samples are collected and placed in the sampling box, the sampling box will be briefly exposed to the room temperature environment, which will cause partial melting of the samples close to the outer wall of the sampling box, thus affecting the accuracy of the detection and evaluation. Therefore, a constant temperature sampling box is designed to solve the above problems. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing food detection sampling boxes, the purpose of the utility model is to provide a constant temperature sampling box, which has the advantages of heat preservation ability in the room temperature environment of the sampling box, etc.

[0004] To achieve the above purpose, a technical solution adopted by the utility model is: a constant temperature sampling box, including a cylindrical inner container, a cylindrical outer barrel, a sealing cover and a stainless steel metal strip. The cylindrical inner container is used for storing samples. A plurality of stainless steel metal strips are radially distributed in the cylindrical outer barrel, and the stainless steel metal strips are parallel to the axis of the cylindrical outer barrel. The cylindrical inner container is detachably embedded in the cylindrical outer barrel. A heat preservation cavity is formed between the cylindrical inner container and the outer barrel of the cylindrical outer barrel. The stainless steel metal strips fit the cylindrical inner container in the cylindrical outer barrel. The sealing cover is buckled at the open end of the cylindrical outer barrel to seal the cylindrical inner container.

[0005] Preferably, the cylindrical inner container is in a transparent state, and the outer diameter of the cylindrical inner container is smaller than the inner diameter of the cylindrical outer barrel.

[0006] Preferably, one side of the sealing cover has a sealing column with a protruding end face, and a sealing ring is also sleeved on the outer edge of the sealing column. The sealing column is used for inserting into the cylindrical inner container for sealing.

[0007] Preferably, the resistance value of the cylindrical inner container being pulled out of the cylindrical outer barrel is N1, and the resistance value of the sealing cover being pulled out of the cylindrical inner container is N2, where N2 > N1.

[0008] Preferably, the cylindrical outer barrel and the sealing cover are made of polyurethane heat preservation materials.

[0009] The beneficial effects of the present utility model are as follows: By pre-cooling the cylindrical outer barrel in a refrigerator, the cooled stainless steel metal strip can cool the cylindrical inner container, so that the samples close to the outer wall of the cylindrical inner container will not melt after being placed in the cylindrical inner container.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0016] Please refer to Figures 1 to 3 , the embodiments of the present utility model include:

[0017] A constant-temperature sampling box, comprising a cylindrical inner container 1, a cylindrical outer barrel 2, a sealing cover 3 and a stainless-steel metal strip 4. The cylindrical inner container 1 is used for storing samples. Inside the cylindrical outer barrel 2, there are multiple radially distributed stainless-steel metal strips 4. The stainless-steel metal strips 4 are parallel to the axis of the cylindrical outer barrel 2. The cylindrical inner container 1 is detachably embedded in the cylindrical outer barrel 2. A heat-insulating cavity 5 is formed between the outer cylinders of the cylindrical inner container 1 and the cylindrical outer barrel 2. The stainless-steel metal strips 4 fit the cylindrical inner container 1 in the cylindrical outer barrel 2. The sealing cover 3 is buckled at the open end of the cylindrical outer barrel 2 to seal the cylindrical inner container 1.

[0018] The cylindrical inner container 1 is in a transparent state, and the outer diameter of the cylindrical inner container 1 is smaller than the inner diameter of the cylindrical outer barrel 2.

[0019] One side of the sealing cover 3 has a sealing post 31 with a protruding end face. An outer ring 6 is also sleeved on the outer edge of the sealing post 31. The sealing post 31 is used for inserting into the cylindrical inner container 1 for sealing.

[0020] The resistance value when the cylindrical inner container 1 is pulled out of the cylindrical outer barrel 2 is N1, and the resistance value when the sealing cover 3 is pulled out of the cylindrical inner container 1 is N2, where N2 > N1. During inspection, since the resistance of the sealing cover 3 pulling out the cylindrical inner container 1 is greater than the resistance of the cylindrical inner container 1 pulling out of the cylindrical outer barrel 2, when the sealing cover 3 is axially removed, it can first drive the extraction of the cylindrical inner container 1, so that the internal samples can be observed through the transparent cylindrical inner container 1.

[0021] The cylindrical outer barrel 2 and the sealing cover 3 are made of polyurethane heat-insulating material.

[0022] Through the above settings, in the actual working process, its specific working principle is as follows:

[0023] Before the sampling work, the cylindrical inner container 1, the cylindrical outer barrel 2 and the sealing cover 3 are all in a separated state. First, the cylindrical outer barrel 2 is placed in a refrigerator for cooling, so that the stainless-steel metal strips 4 are cooled until they reach the same temperature as the refrigerator.

[0024] During the sampling process, first take out the cylindrical outer barrel 2 from the refrigerator, then embed the cylindrical inner container 1 into the cylindrical outer barrel 2, and then sample and put the sample into the cylindrical inner container 1. At this time, the cooled stainless-steel metal strips 4 cool the cylindrical inner container 1, so that after the sample is put into the cylindrical inner container 1, the sample close to the outer wall of the cylindrical inner container 1 will not melt. Then use the sealing cover 3 to buckle at the open end of the cylindrical outer barrel 2 to seal the cylindrical inner container 1. After the sampling is completed, the whole sampling box is directly put into the refrigerator, so that the state of the sample can be continuously maintained.

[0025] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
