[0023] In this embodiment, the cylinder assembly 1 includes a saturation cylinder body 11, a placement barrel 12 and a water diversion cover 13. The saturation cylinder body 11 has a first groove 111, and the first groove 111 is used to evacuate air to form a low-pressure environment; there are multiple placement barrels 12, and multiple placement barrels 12 are placed in the saturation cylinder body 11 to hold a sample saturator so that the sample can be saturated; the water diversion cover 13 includes a baffle 131, a water storage shell 132, a water diversion channel 133, a support ring 134, a guide rod 135 and a floating ring 136. The support ring 134 is slidably connected to the saturation cylinder body 11 and is located in the first groove 111. There are multiple guide rods 135, and multiple guide rods 135 are connected to the saturation cylinder body 11. The support ring 134 is slidably connected and is located around the support ring 134. The floating ring 136 is fixedly connected to the plurality of guide rods 135 and is located on one side of the support ring 134. The floating ring 136 is made of a low-density material, such as plastic, foam, etc., which can provide buoyancy in the liquid. The floating ring 136 can slide relative to the support ring 134 under the support of the guide rods 135 to adjust the distance from the support ring 134. The water container 132 has a first through hole 137. The water container 132 is fixedly connected to the support ring 134 and is located on a side of the support ring 134 away from the floating ring 136. There are multiple water diversion channels 133, and the multiple water diversion channels 133 The baffle 131 is fixedly connected to the support ring 134 and communicated with the first through hole 137. The baffle 131 is fixedly connected to the water housing 132 and is located in the first through hole 137. The saturated liquid from the cylinder head assembly 2 is received in the water housing 132, and slowly flows down along the side wall of the placement barrel 12 through the water guide channel 133, so that the sample saturator can be sequentially infiltrated from bottom to top, avoiding that the bubbles in the sample are difficult to be discharged due to the tension of the gas-liquid interface, making the sample saturated more fully. At the same time, when the liquid submerges the entire sample saturator, the floating ring 136 will float up due to the buoyancy of the liquid, so that the baffle 131 in the water housing 132 blocks the liquid outlet on the cylinder head assembly 2 to avoid more liquid flowing out. , thereby saving materials and improving utilization. Since the heights of the sample saturators are different, the distance between the floating ring 136 and the support ring 134 can be adjusted to adapt to different sample saturators; the cylinder cover assembly 2 includes a cover body 21, a liquid inlet valve 22, an air extraction valve 23, a pressure gauge 24, an air extractor 25 and a liquid inlet pipe 26. The cover body 21 is detachably connected to the saturation cylinder body 11 and covers the first groove 111 to seal the saturation cylinder body 11. There are multiple liquid inlet valves 22, and multiple liquid inlet valves 22 are fixedly connected to the cover body 21 and pass through the cover body 21. Different liquid inlet valves 22 are respectively connected to different solutions, so that different solutions can be provided at the same time for sample saturation;There are multiple liquid inlet pipes 26, and multiple liquid inlet pipes 26 are connected to the liquid inlet valve 22 and are located on the side of the liquid inlet valve 22 close to the baffle 131. The solution enters the water holding shell 132 from the liquid inlet pipe 26; the air extraction valve 23 is fixedly connected to the cover body 21 and is connected to the first groove 111, the vacuum pump 25 is connected to the air extraction valve 23 and is located on one side of the saturated cylinder body 11, the pressure gauge 24 is fixedly connected to the cover body 21 and passes through the cover body 21. By using the vacuum pump 25 and observing the pressure gauge 24, the first groove 111 can be evacuated to the desired low pressure state. Through the multiple liquid inlet valves 22 and the corresponding placement barrels 12, the sample saturation of multiple solutions can be operated at the same time, and then the water guide cover 13 set in the placement barrel 12 guides water to flow down from the side wall to soak the sample from bottom to top to avoid the difficulty of gas discharge. When the liquid is about to immerse the sample saturator, the baffle 131 can block the liquid inlet pipe 26 due to the action of the floating ring 136 to temporarily prevent more solutions from flowing down, thereby saving materials and improving utilization efficiency, solving the problem that the existing saturation cylinder cannot saturate multiple solutions at the same time and the solution utilization rate is low. ;

[0024] Furthermore, the saturation cylinder body 11 has a first handle 112 , which is fixedly connected to the saturation cylinder body 11 and is located on one side of the saturation cylinder body 11 .

[0025] In this embodiment, the first handle 112 is disposed on the saturation cylinder body 11 , so that the saturation cylinder body 11 can be moved by holding the first handle 112 .

[0026] For further information, see Figure 2 The saturation cylinder body 11 has a plurality of clamping columns 113 , and the plurality of clamping columns 113 are located in the first groove 111 .

[0027] In this embodiment, the plurality of clamping columns 113 are used to locate the placement position of the placement bucket 12, so that when the placement bucket 12 is placed into the saturation cylinder body 11, it can be directly placed directly below the liquid inlet pipe 26 without further adjustment.

[0028] Furthermore, the placement bucket 12 has a second handle 121 , which is fixedly connected to the placement bucket 12 and located at one side of the placement bucket 12 .

[0029] In this embodiment, the placement bucket 12 has a second handle 121 , which is convenient for holding the second handle 121 to carry the placement bucket 12 into the saturation cylinder body 11 more labor-savingly.

[0030] Furthermore, the placement bucket 12 has a second scale line 122 , which is located inside the placement bucket 12 , and the guide rod 135 has a first scale line 138 , which is located on a side of the guide rod 135 close to the placement bucket 12 .

[0031] In this embodiment, since the heights of different sample saturators are different, the second scale line 122 is added to mark the height from the liquid outlet tube to the sample saturator, and then the first scale line 138 is marked on the guide rod 135, so that the position of the guide rod 135 can be slid and adjusted according to the value of the second scale line 122, so that the position of the support ring 134 can be adjusted more accurately.

[0032] Furthermore, the water diversion cover 13 has a handle 139 , which is fixedly connected to the water containing shell 132 and is located on one side of the water containing shell 132 .

[0033] In this embodiment, by holding the handle 139, it is more convenient to lift or put down the water diversion cover 13 from the placement bucket 12, making it more convenient and quick during use.

[0034] Furthermore, the water guide cover 13 further includes a guide post 140 , the placement bucket 12 has a guide groove 123 , and the guide post 140 is slidably connected to the placement bucket 12 and is located in the guide groove 123 .

[0035] In this embodiment, the guide column 140 is supported by the guide groove 123 so that the water guide cover 13 will not tilt and can slide more smoothly.

[0036] Furthermore, the cylinder head assembly 2 further includes a pressure relief valve 27 , which is fixedly connected to the cover body 21 and passes through the cover body 21 .

[0037] In this embodiment, when liquid is injected, the air pressure in the saturated cylinder body 11 will gradually rise, which will affect the water absorption saturation of the sample. The traditional method is to observe the pressure gauge 24 and manually adjust the closing degree of the air extraction valve 23, which is very labor-intensive. Therefore, the pressure relief valve 27 is added, the vacuum pump 25 is kept open, and the air extraction valve 23 is closed. The pressure relief valve 27 will open to allow the gas in the saturated cylinder body 11 to be extracted, thereby maintaining the pressure in the saturated cylinder body 11 constant and improving the saturation efficiency of the sample.

[0038] For further information, see Figure 2The cylinder assembly 1 also includes a plurality of shock absorbing springs 28 and a plurality of shock absorbing plates 29. The plurality of shock absorbing springs 28 are fixedly connected to the saturated cylinder body 11 and are located in the clamping column 113. The plurality of shock absorbing plates 29 are respectively fixedly connected to the plurality of shock absorbing springs 28 and are located on one side of the shock absorbing springs 28 close to the cover body 21.

[0039] In this embodiment, when the placing barrel 12 is placed into the saturation cylinder body 11, since the sample saturator has been placed in the placing barrel 12, the weight of the placing barrel 12 is greatly increased. Therefore, it is difficult for human power to smoothly place the placing barrel 12 into the clamping column 113 when placing it into the saturation cylinder body 11. This will cause an impact on the sample saturator and is likely to damage the structure of the sample. Therefore, the shock-absorbing spring 28 and the shock-absorbing plate 29 are added to reduce the impact on the placing barrel 12, thereby protecting the sample saturator from damage due to vibration.

[0040] Working principle and use process of the present invention: please refer to Figure 1 and Figure 2 After the present invention is installed, the sample saturator is placed in the placement barrel 12, and then multiple placement barrels 12 are placed in the saturation cylinder body 11, the cover body 21 is covered, and multiple liquid inlet valves 22 are connected to different solutions, so that different solutions can be introduced into different placement barrels 12 for saturation, the vacuum pump 25 and the vacuum valve 23 are opened to make the first groove 111 in a low pressure state, and the vacuum valve 23 is closed, and multiple liquid inlet valves 22 are opened to slowly inject various solutions into the first groove 111, and the pressure relief valve 27 is opened to keep the low pressure constant, and the solution flows down from the side wall of the placement barrel 12 through the water channel 133, and infiltrates the sample from bottom to top. When the sample is immersed, the solution will push the floating ring 136 to move upward, so that the baffle 131 covers the liquid inlet pipe 26 and prevents the solution from continuing to flow down. When the liquid level drops, the baffle 131 is opened to continue to flow into the solution, thereby saving the solution to improve the utilization rate.

[0041] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention.
