Description

Technical Field

[0001] This utility model relates to the field of sampling and testing equipment technology, specifically a milk sampling and testing device. Background Technology

[0002] To ensure milk safety, assess nutritional value, regulate market quality, and promote industry development, we need to use equipment to sample and test milk.

[0003] A milk testing sampling device described in patent CN222461114U includes a storage box. A liquid pump is fixedly embedded in the top surface of the storage box, and a sampling head is movably embedded in the top of the storage box. An installation plate is movably embedded inside the storage box, and a rotating column is fixedly connected to the top of the installation plate. An installation disc is fixedly fitted around the outer periphery of the rotating column, and multiple sampling containers are movably embedded on the installation disc. A mounting shell covers the top of the sliding cavity, and a switching mechanism is provided inside the mounting shell. This invention features a storage box, allowing for the orderly and organized placement of the necessary sampling equipment within it, facilitating user portability. Furthermore, it includes components such as a meshing block, a driving block, and a meshing port, enabling stable switching of the sampling container once per rotation of the rotating disc without additional operation. This rapid and efficient switching of the sampling container improves sampling efficiency.

[0004] The aforementioned patent can effectively improve the efficiency of milk sampling during use. However, the milk is not filtered during the extraction process. If improper storage or unstable transportation occurs during milk storage or transportation (e.g., excessively high temperature, excessive time, violent vibration, etc.), the proteins, fats, and other components in the milk may denature or separate, forming precipitates and other impurities. These impurities can affect the accuracy of the sampling and testing results and damage the testing instrument. To avoid the impact of impurities on the accuracy of the sampling and testing results, a milk sampling and testing device is now provided, which can eliminate the drawbacks of existing devices.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, such as Figures 1-5 As shown, a milk sampling and testing device includes a sampling tube 1, a sampling head 5 disposed on the lower surface of the sampling tube 1, a first docking ring 4 fixedly connected to the outer wall of the sampling tube 1, a second docking ring 7 fixedly connected to the outer wall of the sampling head 5, the second docking ring 7 being in contact with the lower surface of the first docking ring 4, a connecting ring 6 fixedly connected to the top of the second docking ring 7, the first docking ring 4 being sleeved on the outer wall of the connecting ring 6, the connecting ring 6 being threadedly connected to the first docking ring 4, an infusion hose 3 fixedly connected to the top of the sampling tube 1, the inner cavity of the infusion hose 3 being in communication with the inner cavity of the sampling tube 1, a rubber ring for sealing being disposed between the first docking ring 4 and the second docking ring 7, the end of the infusion hose 3 away from the sampling tube 1 being fixedly connected to the input end of a liquid pump, and a filtering mechanism for filtering milk being disposed on the sampling tube 1.

[0036] The filtration mechanism includes: a filter assembly disposed on the sampling tube 1;

[0037] The filter assembly includes: a filter cylinder 205 disposed inside the sampling tube 1, a limiting ring 206 fixedly connected to the outer wall of the filter cylinder 205, a limiting groove 2010 formed at the junction of the sampling tube 1 and the limiting ring 206, and a plurality of first balls rotatably connected to the sampling tube 1 circumferentially at equal intervals inside the limiting groove 2010, and the plurality of first balls contacting the upper surface of the limiting ring 206.

[0038] The filter cylinder 205 is equipped with a docking assembly;

[0039] A first flow guiding component is provided on the filter cylinder 205;

[0040] In this embodiment, when in use, the port of the sampling head 5 is inserted into the milk that needs to be sampled and tested. At this time, the liquid pump is started, and the milk can be drawn into the storage container through the sampling head 5, the sampling tube 1, and the infusion tubing 3, so that the milk can be sampled and tested.

[0041] During this process, the milk can be filtered through the filter screen 205, thereby separating the impurities in the milk from the milk. Then, the milk enters the inner cavity of the infusion tubing 3 through the sampling tube 1. At the same time, the centrifugal force generated by the filtration mechanism can further improve the filtration effect of the milk, thereby effectively avoiding the impact of impurities on the accuracy of the milk sampling test results.

[0042] When the filter cylinder 205 needs to be cleaned, the sampling head 5 is rotated. At the same time, the connecting ring 6, driven by the sampling head 5, rotates and separates from the first docking ring 4 through the second docking ring 7 via the thread. After cleaning the filter cylinder 205, the above operation is reversed to facilitate the disassembly and installation of the filter cylinder 205, thereby achieving the purpose of convenient cleaning of the filter cylinder 205.

[0043] In one embodiment, such as Figures 2-4 As shown, the docking assembly includes: a docking sleeve 204 fixedly connected to the top of the filter cylinder 205, a docking plate 202 provided on the upper surface of the docking sleeve 204, a docking plug 203 fixedly connected to the bottom end of the docking plate 202, the bottom outer wall of the docking plug 203 being truncated square, the docking sleeve 204 being sleeved on the outer wall of the docking plug 203, and the inner wall of the docking sleeve 204 being in close contact with the outer wall of the docking plug 203;

[0044] A rotating assembly is provided on the docking plate 202;

[0045] The rotating assembly includes: a connecting rotating block 207 fixedly connected to the top of the docking plate 202, and a spiral fan 209 fixedly connected to the top of the connecting rotating block 207;

[0046] A support component is provided on the connecting block 207;

[0047] The support component is a bracket 208 sleeved on the outer wall of the connecting rotating block 207. The connecting rotating block 207 is rotatably connected to the bracket 208, and the bracket 208 is fixedly connected to the sampling tube 1. Through the cooperation of the docking component, the rotating component and the support component, the filter cylinder 205 can be rotated under the impact of the milk. In this way, the centrifugal force generated by the rotation of the filter cylinder 205 can improve the efficiency of milk filtration.

[0048] In one embodiment, such as Figures 2-5 As shown, the first flow guiding component is a first flow guiding ring 201 disposed inside the filter cylinder 205, and the first flow guiding ring 201 is slidably connected to the filter cylinder 205;

[0049] A second flow guiding component is provided on the first flow guiding ring 201;

[0050] The second flow guiding component is a second flow guiding ring 2011 fixedly connected to the bottom end of the first flow guiding ring 201. The second flow guiding ring 2011 is located below the filter cylinder 205 and is fixedly connected to the sampling head 5. Multiple second balls are circumferentially equidistantly connected to the top of the second flow guiding ring 2011. All the multiple second balls are in contact with the lower surface of the limiting ring 206. Through the cooperation of the first flow guiding component and the second flow guiding component, the sampled milk can be guided into the inner cavity of the filter cylinder 205.

[0051] The above embodiment discloses a milk sampling and testing device. When in use, the port of the sampling head 5 is inserted into the milk to be sampled and tested. At this time, the liquid pump is started, and the milk can be drawn into the storage container through the sampling head 5, the sampling tube 1, and the infusion tubing 3, so as to sample and test the milk.

[0052] During this process, guided by the second guide ring 2011 and the first guide ring 201, the milk enters the interior of the filter cylinder 205. The filter cylinder 205 filters the milk, separating impurities from it. The milk then enters the inner cavity of the infusion tubing 3 through the sampling tube 1. Simultaneously, the spiral fan 209, impacted by the milk, drives the connecting rotating block 207 to rotate along the inner wall of the support 208. At this time, the docking insert 203, through the docking plate 202, connects to the rotating block 207. When the filter cylinder 205 is rotated by the docking sleeve 204, the limiting ring 206 rotates inside the limiting groove 2010 under the drive of the filter cylinder 205. At this time, the friction between the limiting ring 206 and the sampling tube 1 and the second guide ring 2011 can be effectively reduced by the first ball and the second ball. In this way, the centrifugal force during the rotation of the filter cylinder 205 can further improve the filtration effect of milk, thereby effectively avoiding the impact of impurities on the accuracy of milk sampling and testing results.

[0053] When the filter cylinder 205 needs to be cleaned, the sampling head 5 is rotated. At the same time, the connecting ring 6, driven by the sampling head 5, rotates and separates from the first docking ring 4 through the second docking ring 7 via the thread. At this time, the second guide ring 2011, driven by the sampling head 5, drives the first guide ring 201 to move synchronously, which can separate the second ball from the outer wall of the limiting ring 206, thereby releasing the limiting ring 206. Then, the limiting ring 206 is pulled to remove the filter cylinder 205 from the inner cavity of the sampling tube 1. At this time, the docking sleeve 204 separates from the docking insert 203 under the drive of the filter cylinder 205. After cleaning the filter cylinder 205, the above operation is reversed to facilitate the disassembly and installation of the filter cylinder 205, thereby achieving the purpose of convenient cleaning of the filter cylinder 205.

[0054] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
