[0033] Reference below Figure 1-Figure 8A soaking device 100 for a sample injection bottle according to an embodiment of the utility model is described. By arranging a tray assembly 2 in a soaking tank 1 and arranging a plurality of sample injection bottles 9 on the tray assembly 2, the stability of the sample injection bottles 9 can be improved, and the sample injection bottles 9 can be prevented from floating and being unable to be completely soaked to remove impurities. That is, after injecting acid into the soaking tank 1, the utility model embodiment can improve the soaking effect of the acid on the soaking tank 1, and the operator is not easily exposed to nitric acid, thereby reducing the risk of the acid corroding the operator's skin or clothes; in addition, after the acid soaks a plurality of sample injection bottles 9 in a soaking tank 1 for 24 hours, one soaking tank 1 can be turned upside down and the acid can be injected into another soaking tank 1 to achieve soaking of the plurality of sample injection bottles 9 in the other soaking tank 1, that is, the soaking liquid can be recycled.

[0034] like Figure 1-8 As shown, a soaking device 100 for a sample injection bottle according to an embodiment of the utility model comprises: a soaking tank 1.

[0035] Among them, each immersion tank 1 is formed with a accommodating cavity and a liquid inlet and outlet 41 selectively connected to the accommodating cavity, and a tray assembly 2 is provided in the accommodating cavity, and the tray assembly 2 is used to place a sample injection bottle 9; wherein, there are at least two immersion tanks 1, and two adjacent immersion tanks 1 are selectively connected through a flexible tube 7, and the liquid in one of the immersion tanks 1 is suitable for selectively flowing to the other immersion tank 1 through the flexible tube 7 after being turned upside down.

[0036] In practice, the injection bottle 9 can be an atomic absorption spectrometer injection vial, which is used to carry and provide the sample to be tested. These injection bottles 9 are usually used to store the sample to be tested to ensure the stability and accuracy of the sample during the measurement process; and the injection bottle 9 usually has some impurities that affect the accuracy of the detection of the components of the sample to be tested. Therefore, by soaking the inside and outer wall of the injection bottle 9 with nitric acid solution, the residual impurities such as heavy metals or minerals on the surface of the injection bottle 9 can be removed. For example, the ratio of nitric acid to water can be set to 1:1 or 1:4, etc., and the heavy metals or minerals can be removed by soaking the injection bottle 9 for 24 hours.

[0037] Specifically, each soaking tank 1 is provided with a tray assembly 2, wherein the tray assembly 2 can be set as one layer or multiple layers, and the tray assembly 2 can remain detachably connected to the soaking tank 1; if the tray assembly 2 includes a plurality of mounting holes 23, when the tray assembly 2 is set as one layer, a plurality of one-to-one corresponding injection bottles 9 can be arranged in the plurality of mounting holes 23, and the tray assembly 2 is mainly suitable for fixing the injection bottles 9 so that the injection bottles 9 can be kept in a fixed position. The injection bottles 9 are made of plastic material, and the injection bottles 9 are fixed by the tray assembly 2, which can prevent the injection bottles 9 from floating on the surface of the acid solution under the action of the acid solution.

[0038] Of course, the tray assembly 2 can also be arranged in multiple layers, and each layer of the tray assembly 2 can be provided with a sampling bottle 9, and a channel for the acid to flow through can be arranged between adjacent tray assemblies 2, so that the acid can reach another layer of the tray assembly 2 from one layer, so as to soak the sampling bottles 9 installed on the tray assemblies 2 of different layers, and also realize the soaking of multiple sampling bottles 9 at the same time, thereby solving the soaking cost and time.

[0039] Furthermore, the number of the immersion tanks 1 can be two, three or more. For example, when the number of the immersion tanks 1 is two, the acid is injected into the first immersion tank 1, and the tray assembly 2 and the injection bottle 9 are placed in the second immersion tank 1 without injecting the acid temporarily. After the acid has soaked the injection bottle 9 in the first immersion tank 1 for 24 hours, the immersion tank 1 can be turned over to allow the acid to be injected into the second immersion tank 1.

[0040] For example, the first soaking tank 1 can be set at a high position and the second soaking tank 1 can be set at a low position, and the acid liquid can flow from the first soaking tank 1 into the other soaking tank 1 by gravity after turning over.

[0041] If the sampling bottle 9 is placed behind the tray assembly 2 with the open mouth facing upward, the soaking tank 1 on the right side needs to be turned over so that the acid can fully flow into the soaking tank 1 on the left side, and the multiple sampling bottles 9 in the second soaking tank 1 are soaked again. When the sampling bottles 9 in the second soaking tank 1 are completely soaked, the acid in the second soaking tank 1 can be poured out or discharged through a liquid inlet and outlet 41. At this time, the sampling bottles 9 in the first soaking tank 1 and the second soaking tank 1 can all be soaked.

[0042] The soaking at this time is only to remove impurities such as heavy metals or minerals remaining in the sampling bottle 9. After the impurities are removed, multiple sampling bottles 9 can be rinsed with clean water, such as injecting clean water through an inlet and outlet liquid port 41 of the first soaking tank 1, and allowing the clean water in the first soaking tank 1 to flow out through another inlet and outlet liquid port 41. Of course, the first soaking tank 1 can also be turned over and the clean water can be poured into the second soaking tank 1. The operation can be repeated many times to clean the sampling bottles 9 in the first soaking tank 1 and the second soaking tank 1.

[0043] It should be noted that, if the number of soaking tanks 1 in the embodiment of the utility model is set to three, acid can be injected into the soaking tanks 1 at both ends, and the acid in the soaking tank 1 at one end can be poured into the middle soaking tank 1 for repeated soaking; when the number of soaking tanks 1 is set to four, only one of the two adjacent soaking tanks 1 needs to be empty, so that the acid in one soaking tank 1 can be poured into another soaking tank 1 for repeated soaking.

[0044] Therefore, the soaking device 100 for the injection bottle of the embodiment of the utility model can not only soak multiple injection bottles 9 to prevent the injection bottles 9 from floating, but also realize the recycling of acid solution to save costs.

[0045] In some embodiments, the top of the immersion tank 1 includes a liquid channel 4, both ends of the liquid channel 4 are provided with liquid inlet and outlet ports 41, the flexible tube 7 is connected between the two liquid inlet and outlet ports 41 corresponding to the two adjacent immersion tanks 1, and the liquid channel 4 is also provided with a liquid injection port 42, and the liquid injection port 42 is selectively connected to the two liquid inlet and outlet ports 41 of the corresponding immersion tank 1 and the accommodating cavity.

[0046] Reference Figure 1 As shown, a first valve 5 and a second valve 6 are provided at the liquid channel 4 of the soaking tank 1, and a liquid injection port 42 is located between the first valve 5 and the second valve 6, that is, when the first valve 5 is opened and the second valve 6 is closed, one liquid inlet and outlet 41 is connected to the interior of the soaking tank 1, and the other liquid inlet and outlet 41 is blocked from connecting to the interior of the soaking tank 1.

[0047] Specifically, the liquid channel 4 is at the top of the soaking tank 1 and along Figure 1 The left and right ends of the liquid channel 4 are each provided with a liquid inlet and outlet 41, the first valve 5 is located on the left side of the liquid injection port 42, and the second valve 6 is located on the right side of the liquid injection port 42. When the first valve 5 is closed and the second valve 6 is opened, when the acid is injected through the liquid inlet and outlet 41 at the right end of the soaking tank 1 on the right side, the acid can flow into the soaking tank 1 along the liquid channel 4, and at this time, the acid in the soaking tank 1 at the right end cannot flow into the soaking tank 1 on the left side, and the acid in the soaking tank 1 on the right side is not effective for the injection. After the bottle 9 is soaked, the first valve 5 of the right soaking tank 1 can be opened and the second valve 6 can be closed. At the same time, the second valve 6 of the left soaking tank 1 can be opened and the first valve 5 can be closed. If the injection bottle 9 is installed in the tray assembly 2, the open mouth of the injection bottle 9 is facing upward, then the soaking tank 1 on the right is turned over, so that the acid in the right soaking tank 1 flows into the left soaking tank 1 through the flexible tube 7. After the acid has circulated, the first valve 5 of the right soaking tank 1 is closed, and the second valve 6 of the left soaking tank 1 is closed.

[0048] That is to say, the liquid channel 4 is connected to the accommodating cavity of the corresponding immersion tank 1 through the liquid injection port 42. At this time, the liquid channel 4 not only integrates the function of injecting the acid solution into the corresponding immersion tank 1, but also allows the acid solution to flow between two adjacent immersion tanks 1. This can be achieved by setting the first valve 5, the second valve 6 and the liquid injection port 42 in the liquid channel 4, and the overall structure is simple.

[0049] In some embodiments, when the sample injection bottle 9 is placed on the tray assembly 2 with the opening facing upward, one soaking tank 1 is adapted to be higher than another soaking tank 1 after being flipped, and liquid flows from one soaking tank 1 to the other soaking tank 1 .

[0050] At this time, when multiple injection bottles 9 are installed in the corresponding tray assembly 2, the open mouth of the injection bottle 9 faces upward, that is, after the acid enters the accommodating chamber of the soaking tank 1, each injection bottle 9 can be smoothly filled to soak the inner wall of the injection bottle 9, and while filling the injection bottle 9, the acid overflows the injection bottle 9 and is located in the accommodating chamber to soak the outer wall of the injection bottle 9, that is, the acid can soak both the inner and outer walls of the injection bottle 9, thereby improving the cleanliness of the injection bottle 9. At this time, if the acid in the soaking tank 1 on the right side needs to be transferred to the soaking tank 1 on the left side, the soaking tank 1 on the right side needs to be turned over, so that the acid in each injection bottle 9 of the soaking tank 1 on the right side can flow smoothly and effectively to the soaking tank 1 on the left side to soak the injection bottle 9 in the soaking tank 1 on the left side.

[0051] In some embodiments, the tray assembly 2 includes multiple layers, the multiple layers of tray assemblies 2 are distributed up and down in the accommodating cavity, and adjacent tray assemblies 2 are supported by support parts 24, and the liquid is suitable for flowing from the upper tray assembly 2 to the lower tray assembly 2.

[0052] Reference Figure 1 and Figure 2 As shown, each soaking tank 1 includes a multi-layer tray assembly 2, and the multi-layer tray assembly 2 is arranged at intervals, and refers to Figure 5 As shown, a support portion 24 can be fixedly or detachably connected to the bottom of a tray assembly 2, and adjacent tray assemblies 2 can be supported by the support portion 24; of course, two or three equal support portions 24 can also be set between adjacent tray assemblies 2 to ensure the spacing between adjacent tray assemblies 2.

[0053] When the acid is injected along one of the liquid inlet and outlet ports 41, the acid can flow along the upper tray assembly 2 to the lower tray assembly 2. For example, the support portion 24 can be set to be hollow, and the support portion 24 is connected to the liquid injection port 42. The liquid injection port 42 is selectively connected to the liquid inlet and outlet ports 41. When connected, after the acid is injected through the liquid inlet and outlet ports 41, it can flow from one layer of tray assembly 2 to another layer of tray assembly 2 through the hollow support portion 24, thereby flowing to the inside of the sample injection bottle 9 installed on the tray assembly 2, and the outside of the sample injection bottle 9 can also be soaked; of course, other feasible methods can also be used to enable the acid to flow from one layer of tray assembly 2 to another layer of tray assembly 2. At this time, the sample injection bottles 9 installed on multiple layers of tray assemblies 2 can be soaked at the same time, which improves the soaking efficiency.

[0054] In some embodiments, each layer of the tray assembly 2 is provided with a plurality of mounting holes 23, and some of the plurality of mounting holes 23 are correspondingly installed with sample injection bottles 9. When liquid is injected into the corresponding immersion tank 1 along the liquid inlet and outlet 41, the liquid is suitable for flowing along the partial mounting holes 23 reserved for the tray assembly 2 of the upper layer to the tray assembly 2 of the lower layer.

[0055] That is, by reserving some mounting holes 23 in each layer of the tray assembly 2 without installing the injection bottles 9, the acid liquid can flow from the reserved mounting holes 23 of the tray assembly 2 of one layer to the tray assembly 2 of another layer, and when the acid liquid flows from multiple reserved mounting holes 23, the resistance is small and the flow speed is fast, so that the acid liquid can quickly flow to the injection bottles 9 of the multi-layer tray assembly 2, thereby improving the liquid injection efficiency. At the same time, the acid liquid can soak both the outer wall and the inner wall of the injection bottles 9 installed at the tray assembly 2, thereby improving the cleaning effect of impurities such as heavy metals or minerals remaining in the multiple injection bottles 9.

[0056] In some embodiments, the injection bottle 9 includes a bottle body 91 and an overlapping portion 92 disposed around the bottle body 91 . The bottle body 91 is installed in the installation hole 23 and the overlapping portion 92 is supported on the tray assembly 2 .

[0057] Reference Figure 8 As shown, the injection bottle 9 includes a bottle body 91 and a lap portion 92, the lap portion 92 can be a boss radially protruding along the outer wall of the bottle body 91, the lap portion 92 is arranged at the upper part of the bottle body 91, and the outer diameter of the lap portion 92 is larger than the diameter of the mounting hole 23, so when the injection bottle 9 is installed in the mounting hole 23 of the tray assembly 2, the lap portion 92 and the tray assembly 2 are limited and supported, so that the injection bottle 9 can be stably installed at the mounting hole 23. In addition, the lap portion 92 is arranged at a position slightly above the center of the bottle body 91 to improve the stability of the injection bottle 9.

[0058] In some embodiments, the tray assembly 2 includes a tray body 21 and a tray cover 22, the mounting hole 23 includes a first mounting hole 211 and a second mounting hole 221 facing each other, the first mounting hole 211 is provided on the tray body 21 and the second mounting hole 221 is provided on the tray cover 22, the bottle body 91 is inserted into the first mounting hole 211 and one end of the overlapping portion 92 is overlapped on the tray body 21, and the tray cover 22 is overlapped on the other end of the overlapping portion 92.

[0059] Combination Figure 5-Figure 7As shown, the tray body 21 is provided with a plurality of first mounting holes 211, and the tray cover 22 is provided with second mounting holes 221 corresponding to the tray body 21 one by one. When the sample injection bottle 9 is installed on the tray body 21, one end of the overlapping portion 92 of the sample injection bottle 9 is overlapped on the tray body 21, and the tray cover 22 is placed on the upper part of the tray body 21, and the second mounting hole 221 of the tray cover 22 is directly opposite to the sample injection bottle 9, so that the tray cover 22 is overlapped on the overlapping portion 92 of the sample injection bottle 9; and when adjacent tray bodies 21 are pressed against each other, such as the support portion 24 connected to the tray assembly 2 of the upper layer is pressed against the tray cover 22 of the tray assembly 2 of the lower layer, the stability between the adjacent tray assemblies 2 is ensured, that is, the stability between the tray body 21 and the tray cover 22 of each layer of the tray assembly 2 is ensured, so that the different positions of the sample injection bottle 9 in the height direction are limited and fixed by the tray cover 22 and the tray body 21 together, thereby improving the reliability of the installation of the tray cover 22 and the tray body 21.

[0060] In some embodiments, the soaking device 100 for the injection bottle further includes a valve stem 3 , the valve stem 3 passes through the multi-layer tray assembly 2 , and the support portion 24 is sleeved on the valve stem 3 .

[0061] Combination Figure 1 and Figure 2 As shown, the valve stem 3 passes through the multi-layer tray assembly 2, that is, in the multi-layer tray assembly 2, adjacent tray assemblies 2 are supported by the support parts 24, and the valve stem 3 connects the multi-layer tray assemblies 2, thereby improving the integrity of the multi-layer tray assembly 2 and preventing the tray assembly 2 from moving in the soaking tank 1. Moreover, the support part 24 can be set at the center of the tray assembly 2. When the tray assembly 2 is connected to the valve stem 3, the support part 24 can be sleeved on the valve stem 3, that is, the middle part of each layer of the tray assembly 2 corresponds to a support part 24, which can ensure the uniformity of the force on the tray assembly 2.

[0062] During installation, the valve stem 3 is passed through the bottom tray assembly 2, and the support portion 24 of the bottom tray assembly 2 is supported on the immersion tank 1, and then the second-layer tray assembly 2 is installed on the valve stem 3, and the support portion 24 of the second-layer tray assembly 2 is supported on the bottom tray assembly 2. After the multi-layer tray assembly 2 is installed, the top tray assembly 2 can be provided with another support portion 24 to support the immersion tank 1. Of course, other methods can also be used to maintain the stability of the top tray assembly 2, thereby ensuring the stability of the multi-layer tray assembly 2.

[0063] In some embodiments, the soaking tank 1 includes a main body portion 11 and a cover portion 12 which are connected to each other. The cover portion 12 is connected to the main body portion 11 and partially presses against the tray assembly 2 on the upper layer.

[0064] That is to say, part of the cover 12 can extend into the main body 11 of the soaking tank 1, and after extending, the cover 12 and the tray assembly 2 are pressed against each other, which is equivalent to maintaining the stability of the uppermost tray assembly 2, and other adjacent tray assemblies 2 are mutually supported by the support portion 24, and after the uppermost tray assembly 2 is stable, the stability of the other multiple tray assemblies 2 at the lower layer can be guaranteed. It should be noted that when part of the cover 12 extends into the main body 11, a sealing material or other structural design can be used to maintain the sealing between the cover 12 and the main body 11.

[0065] In some embodiments, the cover body 12 includes an outer shell 122 and an inner fixing portion 121, the outer wall of the inner fixing portion 121 is provided with an outer thread, the inner wall of the main body 11 is provided with an inner thread, the inner fixing portion 121 extends into the main body 11 to be threadedly connected with the main body 11 and pressed against the edge of the upper tray assembly 2, and the outer shell 122 is arranged around the outer periphery of the main body 11.

[0066] Combination Figure 3 and Figure 4 As shown, there is a gap between the outer shell 122 and the inner fixing part 121, and the gap can adapt to the wall thickness of the soaking tank 1, which is equivalent to the inner fixing part 121 being constructed as an inner ring, and the outer shell 122 includes an outer ring, and the outer ring and the inner ring are connected at one end along the axial direction, thereby forming the cover body 12, then an external thread is arranged on the outer wall of the inner fixing part 121, and an internal thread is arranged on the inner wall of the main body 11 of the soaking tank 1, when the inner fixing part 121 extends into the main body 11, the inner fixing part 121 is pressed against the uppermost tray assembly 2, and the inner fixing part 121 and the main body 11 of the soaking tank 1 are threadedly connected, the connection is convenient and the reliability is good, the inner fixing part 121 is pressed against the edge of the uppermost tray assembly 2, to ensure the stability of the uppermost tray assembly 2.

[0067] The inner fixing portion 121 presses against the edge of the tray assembly 2, and can also avoid the sample injection bottle 9, preventing the acid from having difficulty entering due to the pressure on the sample injection bottle 9. In addition, pressing against the edge of the tray assembly 2 can also improve the force uniformity of the tray assembly 2 and leave a larger space between the tray assembly 2 and the cover body 12, so that the acid can enter the immersion tank 1 more smoothly.

[0068] In some embodiments, a deflation valve 8 is further provided at the bottom of the soaking tank 1 , and the deflation valve 8 is suitable for opening and deflation when one soaking tank 1 is turned over and liquid enters another soaking tank 1 .
