Description

Technical Field

[0001] This utility model belongs to the field of material storage technology, specifically relating to a sealed sampling device. Background Technology

[0002] In industries such as chemical, food, and pharmaceutical, many materials, due to their unique physicochemical properties, must be stored in an airtight environment; otherwise, they are highly susceptible to contamination or deterioration. Traditional storage methods typically involve sealing materials in ordinary containers.

[0003] During material storage, when samples are taken from the storage bins for testing, some air from the external environment can easily enter the bins, bringing in dust, microorganisms, moisture, and other harmful impurities. These pollutants can not only directly mix into the materials, causing component contamination, but may also trigger chemical reactions or microbial growth, thereby reducing the purity and stability of the materials and potentially leading to product defects.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a sealed sampling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sealed sampling device includes a storage tank, an external connector fixed to the outer wall of the storage tank, a second inner cavity opened inside the external connector, a suction cup communicating with the second inner cavity fixed to the outer wall of the external connector, a release component communicating with the second inner cavity provided on the external connector, and a blow-proof component communicating with the interior of the storage tank provided at the top of the storage tank.

[0007] Preferably, the blow-proof assembly includes an end tube fixed to the top of the storage tank and communicating with the inside of the storage tank. The end tube has a first inner cavity in its side wall, an air hole communicating with the first inner cavity is opened on the inner side wall of the end tube, and an air inlet pipe communicating with the first inner cavity is fixed on the outer side wall of the end tube.

[0008] Preferably, the air blowing holes are provided in multiple locations and are equidistantly distributed, and the top end of the end cylinder is hinged with a cover plate.

[0009] Preferably, the air inlet is inclined upwards.

[0010] Preferably, the release assembly includes an outer cylinder fixed to the outer wall of the outer connector and communicating with the second inner cavity. The outer cylinder has a threaded rod internally threaded to one end away from the outer connector. A piston plate that fits tightly against the inner wall of the outer cylinder is fixed to one end of the threaded rod. A vent hole communicating with the interior of the outer cylinder is provided on the side of the outer cylinder.

[0011] Preferably, an end plate is fixed to one end of the threaded rod located outside the outer cylinder, and a rubber sleeve is fitted onto the surface of the end plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. By uniformly and finely spraying nitrogen upwards through the set blowing and shielding components, air and impurities in the external environment are isolated from entering the interior of the storage tank, thus avoiding the problem of air in the external environment contaminating the materials inside the storage tank. This effectively solves the problem that air and impurities in the external environment can easily enter the interior of the storage tank during sampling, and effectively improves the protection of the materials inside the storage tank. 2. When the storage tank is placed, it is attached to the wall by the suction cups, thus fixing the storage tank to the wall and stabilizing the placement of the storage tank, preventing the storage tank from easily tipping over due to external forces, and further improving the protection of the materials inside the storage tank; 3. When the storage container needs to be moved, the set release component can quickly allow air from the outside environment to enter the interior of the external base, and then into the interior of the suction cup, thereby quickly releasing the suction cup's adhesion and making it easy to move the storage container, effectively improving ease of use.

[0018] See attached document Figure 1-5A sealed sampling device includes a storage tank 3, an outer connector 4 fixed to the outer wall of the storage tank 3, a second inner cavity 6 formed inside the outer connector 4, a suction cup 5 fixed to the outer wall of the outer connector 4 communicating with the second inner cavity 6, a release component 1 communicating with the second inner cavity 6 on the outer connector 4, and a blowing component 2 communicating with the interior of the storage tank 3 at the top of the storage tank 3. During sampling, a sampling tube is inserted into the interior of the storage tank 3 through an end tube 201. During this process, nitrogen gas is uniformly and finely sprayed upwards by the blowing component 2, thereby isolating air and impurities from the external environment from entering the interior of the storage tank 3 and preventing contamination of the material inside the storage tank 3 by air from the external environment. This design effectively solves the problem of air and impurities from the external environment easily entering the storage tank 3 during sampling, thus significantly improving the protection of the materials inside the storage tank 3. When the storage tank 3 is placed, it is adhered to the wall by the suction cup 5, thereby fixing the storage tank 3 to the wall and stabilizing its placement. This prevents the storage tank 3 from easily tipping over due to external forces, further improving the protection of the materials inside the storage tank 3. When it is necessary to move the storage tank 3, the release component 1 allows air from the external environment to be quickly introduced into the external base 4, and then into the suction cup 5, thereby quickly releasing the suction cup 5 and facilitating the transfer of the storage tank 3, effectively improving ease of use.

[0019] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the blowing and blocking assembly 2 includes an end tube 201 fixed to the top of the storage tank 3 and communicating with the interior of the storage tank 3. A first inner cavity 203 is formed in the side wall of the end tube 201, and an air blowing hole 204 communicating with the first inner cavity 203 is formed on the inner side wall of the end tube 201. An air inlet pipe 205 communicating with the first inner cavity 203 is fixed on the outer side wall of the end tube 201. During sampling, a sampling tube is inserted into the interior of the storage tank 3 through the end tube 201 to collect the sample. An external air pump is connected to the air inlet pipe 205. Nitrogen gas with a certain pressure is introduced into the first inner cavity 203 through the air inlet pipe 205. The nitrogen gas is then sprayed upwards in a uniform and fine manner through multiple air blowing holes 204, thereby isolating air and impurities from the external environment from entering the interior of the storage tank 3. This prevents the air from the external environment from contaminating the material inside the storage tank 3, effectively solving the problem that air and impurities from the external environment can easily enter the interior of the storage tank 3 during sampling, and effectively improving the protection of the material inside the storage tank 3.

[0020] Further as Figure 3As shown, it is worth noting that there are multiple air holes 204, and the multiple air holes 204 are distributed at equal intervals. The top end of the end cylinder 201 is hinged with a cover plate 202. In actual operation, the top opening of the end cylinder 201 is sealed by the cover plate 202.

[0021] Further as Figure 3 As shown, it is worth noting that the air blowing hole 204 is set at an angle upwards; in actual operation, the air blowing effect is improved by using the air blowing hole 204 set at an angle upwards.

[0022] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the release component 1 includes an outer cylinder 101 fixed to the outer wall of the outer seat 4 and communicating with the second inner cavity 6. The outer cylinder 101 has a threaded rod 105 internally threaded at one end away from the outer seat 4. A piston plate 102 is fixed to one end of the threaded rod 105 and fits tightly against the inner wall of the outer cylinder 101. A vent hole 103 communicating with the interior of the outer cylinder 101 is provided on the side of the outer cylinder 101. When it is necessary to transfer the storage container 3, by rotating the threaded rod 105, the piston plate 102 is moved inside the outer cylinder 101, so that the piston plate 102 passes through the vent hole 103. Thus, air from the outside environment can enter the suction cup 5 through the vent hole 103, thereby quickly releasing the suction cup 5 from its adhesion and making it convenient to transfer the storage container 3, effectively improving the ease of use.

[0023] This solution includes the following working process: During sampling, the sampling tube is inserted into the storage tank 3 through the end tube 201. During this process, an external air pump is connected to the air inlet pipe 205, and nitrogen gas with a certain pressure is introduced into the first inner cavity 203 through the air inlet pipe 205. The nitrogen gas is then evenly and finely sprayed upwards through multiple air blowing holes 204, thus isolating external air and impurities from entering the storage tank 3 and preventing contamination of the material inside the storage tank 3. When the storage tank 3 is placed, [the following steps are taken]... The suction cup 5 is attached to the wall, thus fixing the storage bucket 3 to the wall and stabilizing its placement, preventing it from tipping over easily due to external forces. When the storage bucket 3 needs to be moved, the threaded rod 105 is rotated, which moves the piston plate 102 inside the outer cylinder 101. This causes the piston plate 102 to pass over the vent hole 103, allowing air from the outside environment to enter the suction cup 5. This quickly releases the suction cup 5 from its attachment, facilitating the transfer of the storage bucket 3.

[0024] Further as Figure 5As shown, it is worth noting that an end plate 104 is fixed on one end of the threaded rod 105 located outside the outer sleeve 101, and a rubber sleeve is fitted on the surface of the end plate 104. In actual operation, the threaded rod 105 can be easily rotated and adjusted by the end plate 104, which is convenient for operation. The rubber sleeve increases the friction when holding the end plate 104 and prevents slippage.

[0025] In summary: By uniformly and finely spraying nitrogen upwards through the blowing and shielding component 2, air and impurities from the external environment are isolated from entering the interior of the storage tank 3, preventing contamination of the material inside the storage tank 3 by external air. This effectively solves the problem of air and impurities easily entering the storage tank 3 during sampling, significantly improving the protection of the material inside the storage tank 3. When the storage tank 3 is placed, it is adhered to the wall by the suction cup 5, thus fixing the storage tank 3 to the wall and stabilizing its placement, preventing it from easily tipping over due to external forces, further improving the protection of the material inside the storage tank 3. When the storage tank 3 needs to be moved, the release component 1 allows air from the external environment to quickly enter the interior of the external connector 4, and then into the interior of the suction cup 5, quickly releasing the suction cup 5 and facilitating the transfer of the storage tank 3, effectively improving ease of use.
