Detailed implementation mode

[0027] The following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0028] It should be understood that terms such as "having", "including", and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0029] As Figures 1-8 shown, the present invention provides a milk component quantitative detection device, including: a component analysis device disposed in the chassis 1, and a terminal 2 electrically connected to the component analysis device. The component analysis device includes, but is not limited to, devices for component analysis using physical methods (such as spectral analysis, density analysis, refractive index analysis, etc.), devices for component analysis using chemical methods (such as titration method, Kjeldahl method, etc.), and devices for component analysis using biological methods (such as enzyme-linked immunosorbent assay, etc.). All of the above are commercially available products or existing technologies; the chassis 1 is also an upper concept, and the number of chassis 1 can be one or more. For example, a spectrometer and a mass spectrometer can be placed in two chassis 1 respectively, or integrated into one chassis 1. The terminal 2 is used to display components and operate the device. Different from the prior art, at least one storage tank is disposed in the chassis 1. The storage tank is communicated with the component analysis device through a feeding device. The feeding device is electrically connected to the terminal 2, and the storage tank is detachably connected to the feeding device.

[0030] Working principle and beneficial effects of the above technical solution: Through the design of the above structure, the storage tank exists as an independent individual. The storage tank is usually a sealed container, and the filling volume of the liquid in each storage tank is the same. Each storage tank is connected to the component analysis device through a feeding device. The feeding device can be one. All storage tanks are connected to the feeding device and convey the liquid to different component analysis devices through this feeding device. See the first embodiment. This embodiment usually uses the same milk source for quantitative distribution to different component analysis devices, avoiding the exposure of the liquid outside and reducing the intrusion of impurities to affect the test results. The feeding device can also be multiple, and one feeding device is correspondingly set for each storage tank. See the second embodiment. This embodiment usually uses different milk sources for quantitative distribution to the same component analysis device. The feeding device in this embodiment can clean the pipeline for transporting the liquid. And in the case of only one feeding device, different milk sources (such as raw milk at the time of raw milk entering the factory, standardized milk, homogenized milk, pasteurized milk, and finished milk before leaving the factory) can be replaced by replacing different storage tanks, greatly optimizing the volume of the detection equipment. No matter which implementation mode is adopted, through the detachable connection mode between the storage tank and the feeding device, in the case of only one feeding device, it is possible to supplement or replace the milk by replacing the storage tank, thus greatly optimizing the volume of the detection equipment. The storage tank to be replaced can be stored refrigerated to avoid affecting the test results due to temperature. Because the storage tank can seal the sample, and the storage tank is directly connected to the component analysis device through the feeding device, it can avoid manual sampling and at the same time avoid multiple transfers of the sample, thereby avoiding sample contamination and improving the accuracy of sample component analysis.

[0031] When different component analysis devices perform component analysis on the milk of the same milk source, a large amount of sample is required. To ensure an adequate supply of the sample and ensure that the same sample is used by different component analysis devices, a large amount of sample milk needs to be stored in the storage tank. However, if a large amount of sample milk is stored, there will be problems such as a large volume of the storage tank, difficulty in realizing or maintaining the storage conditions of the sample milk, the need for multiple transfers of the sample, and an increase in the cleaning difficulty of the storage tank. Therefore, we provide the first embodiment to ensure that there is enough sample for component analysis, while not requiring a large-capacity storage tank, reducing the number of sample transfers, reducing the cleaning difficulty of the storage tank, and reducing the storage difficulty of the sample milk.

[0032] In this embodiment, the storage tank is the first storage tank 3. The first storage tank 3 is in the shape of a test tube. One end of the first storage tank 3 has an opening for quantitative filling of the sample milk, and a detachable first cover 4 is provided at the opening to seal the filled first storage tank 3. Thus, a number of first storage tanks 3 filled with the same mass of sample milk can be obtained.

[0033] In this embodiment, the feeding device is the first feeding device, and a first connector 5 is provided on the first feeding device. The first connector 5 penetrates through the first cover 4 and extends into the interior of the first storage tank 3. The sample milk inside the first storage tank 3 can reach the first feeding device through the first connector 5 and enter the component analysis device via the first feeding device.

[0034] When performing component analysis, a plurality of first storage tanks 3 are taken out from the cold storage (or any storage device for storing the first storage tank 3) (for example, each first storage tank 3 stores 200 ml of sample milk. When 700 ml of sample milk is needed, 4 first storage tanks 3 can be used) and placed in the chassis 1, as Figure 1 shown. At this time, the first storage tank 3 is still in a sealed state, so that the sample milk can be prevented from contacting the external environment during the transfer process and the waste of the sample milk can be reduced while ensuring an adequate sample volume. Then, the first connector 5 is connected to the first storage tank 3, and the first feeding device can supply the sample milk to the component analysis device quantitatively as needed. Usually, the first feeding device is a commercially available product or existing technology capable of transporting the sample milk to the component analysis device. For example, the first feeding device can be a peristaltic pump. The connection between the first feeding device and the first connector 5 can be a one-to-one connection relationship (usually used for component analysis devices with a small demand for sample milk), or a one-to-N connection relationship (usually used for component analysis devices with a large demand for sample milk). It is also possible for multiple component analysis devices to share a first feeding device, and the first feeding device is provided with a plurality of first connectors 5 (usually used when multiple component analysis devices are arranged in a chassis 1). Since the same sample milk is detected, usually multiple component analysis devices are integrated into a single chassis 1 to save the volume of the device.

[0035] Further, the first cover 4 is composed of a cover plate 41, and inner connection ends 42 and outer connection ends 43 provided on both sides of the cover plate 41. The diameter of the cover plate 41 is not less than the diameter of the opening of the first storage tank 3, so that the cover plate 41 can block the opening of the first storage tank 3. A first connection hole is provided on the cover plate 41, so that the first connector 5 can enter the first storage tank 3. The inner connection ends 42 and the outer connection ends 43 are both tubular, and the inner connection ends 42 and the outer connection ends 43 are communicated through the first connection hole. The inner connection ends 42 are located inside the first storage tank 3, and the outer wall of the inner connection ends 42 is connected to the inner wall of the first storage tank 3 (either by plugging or screwing), as Figure 3As shown, a first seal 6 that can be punctured by the first connector 5 is provided inside the inner connection end 42. The first seal 6 is an elastic disc, and the diameter of the first seal 6 is not less than the inner diameter of the inner connection end 42. When the first storage tank 3 is not in use, the first seal 6 can block the first connection hole, so that the sample milk in the first storage tank 3 can be sealed.

[0036] The first connector 5 is composed of a wiring tube 51 and a puncture needle 52. One end of the wiring tube 51 is connected to the component analysis device through a first feeding device for supplying sample milk to the component analysis device, and the other end is connected to one end of the puncture needle 52. When the first storage tank 3 is in use, the other end of the puncture needle 52 punctures the first seal 6 and extends into the first storage tank 3, so that the sample milk in the first storage tank 3 can flow to the wiring tube 51 through the puncture needle 52. An outer member 53 is provided on the outer wall of the connection between the wiring tube 51 and the puncture needle 52. The outer member 53 is usually an elastic cylindrical structure. The first connector 5 is connected to the outer connection end 43 through the outer member 53, so as to prevent the puncture needle 52 from coming out of the first storage tank 3.

[0037] Generally, the first implementation mode is mostly used in the case of integrating multiple component analysis devices in a single chassis 1, and usually the first feeding device adopts a peristaltic pump that does not come into contact with the sample milk. Thus, the wiring tube 51 can be directly connected to the component analysis device. After the detection of a batch of sample milk is completed, the wiring tube 51 can be directly removed from the component analysis device, and the connection between the component analysis device and the wiring tube 51 can be cleaned. The wiring tube 51, the puncture needle 52, and the first storage tank 3 can be cleaned separately for repeated use.

[0038] Furthermore, when one component analysis device is provided in each chassis 1, it is usually necessary to continuously detect multiple batches of samples. For example, it is necessary to sequentially detect raw milk at the time of raw milk entering the factory, standardized milk, homogenized milk, pasteurized milk, and finished milk before leaving the factory. At this time, the first implementation mode can still be adopted, but because the wiring tube 51 needs to be disassembled and assembled each time, and the interface of the component analysis device needs to be cleaned frequently, the operation is relatively cumbersome and time-consuming for labor. Therefore, we provide a second implementation mode.

[0039] In this embodiment, the storage tank is the second storage tank 7. Both ends of the second storage tank 7 have openings, which are a first opening with a diameter of r and a second opening with a diameter of R respectively, where r < R, as Figure 6 and Figure 7As shown; a detachable second cover 8 is provided at the first opening, and the first opening is threadedly connected to the outer wall of the second cover 8. A second seal 9 is provided on the inner wall of the second storage tank 7, near the second opening. There is a first distance between the surface of the second seal 9 inside the second storage tank 7 and the surface of the second cover 8 inside the second storage tank 7, thereby forming a variable-capacity accommodation space for storing sample milk quantitatively. Similar to the first storage tank 3, the mass of the sample milk stored in each second storage tank 7 is the same. The difference from the first storage tank 3 is that in use, the opening of the first storage tank 3 is upward, as Figure 1 shown, the first opening of the second storage tank 7 is downward, as Figure 4 shown.

[0040] The feeding device is the second feeding device 10, and the second storage tank 7 is connected to the second feeding device 10 through the second cover 8. The second seal 9 is an elastic member, and the second seal 9 is hemispherical, as Figure 7 shown. When the second storage tank 7 is not in use, the second seal 9 protrudes towards the second opening. When using the second storage tank 7, only by pressing down the second seal 9, the sample milk in the second storage tank 7 can be pressed out of the second storage tank 7.

[0041] During the pressing process, the protruding direction of the second seal 9 will change to protrude towards the first opening. At this time, in order to be able to further press down the second seal 9 and, after the pressing is completed, be able to reset the second seal 9 to protrude upward, a second connector 91 is provided on the surface of the second seal 9 facing the second opening. The second seal 9 is connected to a transmission device provided on the chassis 1 through the second connector 91. The second connector 91 is usually a permanent magnet attached to the surface of the second seal 9, or can also be other commercially available products or existing technologies that can be connected to the transmission device.

[0042] The transmission device is located outside the second storage tank 7. The transmission device consists of a drive motor 111 and a telescopic rod 112. One end of the telescopic rod 112 is connected to the drive motor 111, and the other end extends from the second opening into the second storage tank 7 and selectively connects to the second connector 91. When sample milk needs to be supplied, the drive motor 111 drives the telescopic rod 112 to move downward, connects it to the second connector 91, and continuously pushes down the second seal 9. Since the telescopic rod 112 first connects to the second connector 91 and then pushes the second seal 9 downward, there will be no instant of rapid deformation during the process of the second seal 9 changing from protruding upward to protruding downward, avoiding affecting the sample milk supply rate.

[0043] One end of the second cover 8 is connected to the first opening (usually by screw connection), and the other end is conical with a third opening. The opening area near the conical tip of the third opening is larger than that at the conical root, as Figure 6 and Figure 7 shown. When the second cover 8 is connected to the second feeding device 10, the conical end of the second cover 8 is inserted vertically downward onto the second feeding device 10, so that discharging the sample milk at the conical tip of the second cover 8 will not affect the discharging rate. At the same time, the conical structure design enables the cleaning liquid to slide down along the cone into the second feeding device 10 during the cleaning of the second feeding device 10. The third opening with a gradually decreasing opening area can block the liquid in the second storage tank 7. When no pressure is applied to the second seal 9, it can prevent the sample milk from entering the second feeding device 10, thus avoiding the secondary entry of the sample milk into the second feeding device 10 during the cleaning process and causing contamination to it. A second connection hole communicating with the third opening is provided in the second cover 8. A third seal 12 is provided in the second storage tank 7. The third seal 12 is composed of a sealing disk 121 and a connecting column 122. The connecting column 122 is arranged on the central axis of the sealing disk 121 and extends into the second connection hole. A third connection hole is provided on the connecting column 122. The second connection hole communicates with the interior of the second storage tank 7 through the third connection hole. The outer wall of the sealing disk 121 is connected to the inner wall of the second storage tank 7. As Figure 7 shown, the third seal 12 can effectively prevent the sample milk from leaking out from the first opening when the second seal 9 compresses the accommodation space.

[0044] Further, the second feeding device 10 is composed of an N-way 101 with n interfaces and a solenoid valve 102. The n interfaces of the N-way 101 include a tank interface 10a arranged vertically and a solenoid valve interface, and m material interfaces arranged horizontally, where m≥0. Taking n = 4 and m = 2 as an example, the N-way is a four-way with 4 interfaces. The tank interface 10a is located above the solenoid valve interface. A detachable sealing cap 1011 is provided on the tank interface 10a. When the second storage tank 7 is not installed, the sealing cap 1011 seals the tank interface 10a to prevent impurities from entering the four-way. A solenoid valve 102 is provided at the solenoid valve interface and is connected to the component analysis device through the solenoid valve 102. The solenoid valve 102 is used to control the amount of sample milk entering the component analysis device. The material interfaces are connected to the material supply end. The material supply end can be a cleaning liquid supply end for cleaning the second feeding device 10, or a water supply end; it can also be a reactant supply end for supplying reaction materials to the component analysis device (using chemical or biological methods); it can also be a steam supply end for supplying steam to clean the second feeding device 10.

[0045] Furthermore, since a material supply end is provided, there may be a situation where the pressure inside the second feeding device 10 is too high. To prevent the second storage tank 7 and the sealing cap 1011 from being blown off, the inner wall of the tank interface 10a is provided with internal threads, and the outer wall of the second cover 8 is provided with external threads and a clamping platform. The second cover 8 is threadedly connected to the tank interface 10a.
