[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In one embodiment of the utility model, a water circulation system suitable for microscopic section imaging is provided, in which the water tank can be continuously sucked, filtered, and automatically replenished with water, and the liquid level of the sample imaging solution in the water tank can be kept constant, thereby ensuring the imaging effect. Figure 1 The figure further describes the water circulation system suitable for microscopic section imaging in this embodiment.

[0021] Specifically, if Figure 1 As shown, the water circulation system suitable for microscopic section imaging in this embodiment includes: a water tank 1, a chip suction pipe 2, a water pump 6, a water outlet pipe 7, a filter 8, a return pipe 9, a water supply pipe 3 and a water supply tank 5.

[0022] The first end of the chip suction pipe 2 is inserted into the water tank 1, and the second end is connected to the water inlet of the water pump 6;

[0023] The first end of the water outlet pipe 7 is connected to the water outlet of the water pump 6, and the second end is connected to the inlet of the filter 8;

[0024] The first end of the water return pipe 9 is connected to the outlet of the filter 8, and the second end is connected to the bottom of the water tank 1;

[0025] The first end of the water supply pipe 3 is inserted into the water tank 1, and the second end is inserted into the water supply tank 5;

[0026] Among them, in the vertical direction, the first end of the chip suction pipe 2 is lower than the first end of the water supply pipe 3 , and the first end of the water supply pipe 3 is higher than the second end of the water supply pipe 3 .

[0027] For example, in order to facilitate observation of the state of the liquid in the sink, the sink 1 may be made of a transparent plastic cup or a glass cup.

[0028] Exemplarily, in order to facilitate installation, the chip suction pipe 2, the water outlet pipe 7, the water return pipe 9 and the water supply pipe 3 can all be rubber hoses, and in order to facilitate the flow of liquid in the pipeline, transparent hoses can be particularly selected.

[0029] Exemplarily, in order to achieve effective filtration, the filter 8 includes: a filter box and filter cotton.

[0030] The filter box is made of 5mm thick transparent acrylic, which is light in weight and low in cost.

[0031] The filter cotton is fixedly arranged in the filter box. In this embodiment, the filter cotton is fixedly arranged in the filter box by bolts. In other embodiments, the filter cotton can be fixedly arranged in the filter box by other means such as axle pins. The filter cotton adopts 1000 mesh nylon black yarn plus three layers of biochemical filter cotton, and the filtering accuracy reaches the micron level, which is corrosion-resistant and not easy to clog.

[0032] The second end of the water outlet pipe 7 is connected to the top of the filter box, and the first end of the water return pipe 9 is connected to the bottom of the filter box. Under the action of gravity, the liquid entering the filter box through the water outlet pipe 7 can fall and pass through the filter cotton. After reaching the bottom of the filter box, the clean water without impurities after filtering flows back to the water tank 1 through the water return pipe 9.

[0033] Exemplarily, the water pump 6 is a micro gear pump.

[0034] Further, the system also includes: an additional pipe 4, the first end of which is inserted into the water supply tank 5, and the second end of which is connected to the water suction port of the water pump 6, that is, the second end of the scrap suction pipe 2 and the second end of the additional pipe 4 are connected to the water pump 6, and in the water supply tank 5, the second end of the water supply pipe 3 is higher than the first end of the additional pipe 4. Thus, the water pump 6 can also pump the liquid in the water supply tank 5 to the filter 8 through the additional pipe 4.

[0035] In actual use, Figure 1 As shown, when the preset liquid level height of the sample imaging solution in the water tank 1 needs to be set at point P, in the water tank 1, the first end of the water supply tube 3 can be fixed to be flush with point P, and the first end of the chip suction tube 2 can be fixed below point P; in the water supply tank 5, the second end of the water supply tube 3 can be fixed below point P.

[0036] Therefore, when the water pump 6 works normally, the water pump 6 can pump the sample imaging solution in the water tank to the filter 8 via the suction pipe 2 and the outlet pipe 7, and the filtered sample imaging solution can return to the water tank 1 again via the return pipe 9.

[0037] During the normal operation of the water pump 6, the water pump 6 can continuously pump the sample imaging solution in the water tank 1 to the filter 8 through the chip suction pipe 2. When the liquid level of the sample imaging solution in the water tank 1 is higher than point P, the sample imaging solution in the water tank 1 will also enter the water replenishment tank 5 through the water replenishment pipe 3, and then enter the filter 8 through the outlet pipe 7 under the action of the water pump 6, so that the liquid level of the sample imaging solution in the water tank 1 can be reduced. When the liquid level of the sample imaging solution in the water tank 1 is lower than point P, the sample imaging solution in the water tank 1 cannot enter the water replenishment tank 5 through the water replenishment pipe 3. Since the water pump 6 can pump the liquid in the water tank 1 to the filter 8 through the chip suction pipe 2, and there is also liquid in the return pipe 9 returning to the water tank 1, the power of the water pump 6 can be adjusted so that the amount of water entering the water tank 1 through the return pipe 9 is greater than the amount of water pumped by the water pump 6, so that the liquid level of the sample imaging solution in the water tank 1 can be increased. When the liquid level of the sample imaging solution in the water tank 1 is flush with point P, the amount of water entering the filter 8 through the chip suction pipe 2 and the water supply pipe 3 is equal to the amount of water entering the water tank 1 through the return pipe 9, so that the liquid level of the sample imaging solution in the water tank 1 can be kept flush with point P.

[0038] In this embodiment, the height of the return pipe 9 needs to be lower than the height of the bottom of the water tank 1 to effectively avoid bubble blockage in the pipe that affects the return water speed and prevent overflow in the water tank from damaging the equipment.

[0039] In one embodiment, the position of the filter 8 is higher than that of the water tank 1. It can be understood that, through this arrangement, under normal atmospheric pressure, the liquid filtered in the filter 8 can be effectively returned to the water tank 1 through the return pipe 9. Alternatively, a return water pump can be provided on the return water pipe 9 to allow the return water pump to effectively pump the filtered liquid in the filter 8 to the water tank 1.

[0040] In one embodiment, the system further includes: a first end cover, which is disposed on the top of the water tank 1, through which the chip suction pipe 2 and the water supply pipe 3 pass and are inserted into the water tank 1, and the first end cover is also provided with a vent hole.

[0041] Therefore, with the help of the first end cover, the chip suction pipe 2 and the water supply pipe 3 can be effectively fixed, and the first end cover is also provided with a vent hole to ensure that the liquid in the water tank can flow normally to the water supply tank 5 through the water supply pipe 3.

[0042] As described above, in this embodiment, the filter 8 includes a filter box, and in this regard, the system also includes: a second end cover, the second end cover is arranged on the top of the filter box, the water outlet pipe 7 passes through the second end cover and is inserted into the filter box, and the second end cover is also provided with a vent hole.

[0043] Similarly, with the help of the second end cover, the water outlet pipe 7 can be effectively fixed. Moreover, the second end cover is also provided with a vent hole to ensure that the liquid in the filter box can flow normally to the water tank 1 through the return pipe.

[0044] In one embodiment, in order to ensure that the liquid in the water tank 1 that is higher than a preset height can flow normally to the water supply tank 5 through the water supply pipe 3 , a water supply pump is also provided on the water supply pipe 3 .

[0045] In actual use, when the liquid in the water tank 1 is higher than the first end of the water replenishment pipe 3, the water replenishment pump can promptly pump the liquid in the water tank 1 above the first end of the water replenishment pipe 3 into the water replenishment tank 5 to maintain the liquid level in the water tank 1.

[0046] Therefore, the water circulation system suitable for microscopic section imaging in this embodiment has the following advantages:

[0047] In the water circulation system suitable for microscopic section imaging in this embodiment, the water pump can continuously pump the sample imaging solution in the water tank to the filter, and the sample imaging solution filtered by the filter will return to the water tank, which can realize the functions of suction, filtering, automatic water replenishment, etc. Moreover, the water replenishment pipe can continuously suck the sample imaging solution in the water tank into the water replenishment tank, so that the liquid level of the sample imaging solution in the water tank remains unchanged, the liquid level can be maintained, and the imaging effect can be ensured. At the same time, the entire system realizes modular design and assembly, with low cost, which is conducive to reducing equipment costs, good stability, can improve the stability of the equipment during operation, and the system operation and subsequent maintenance are also more convenient.

Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
