Description

Technical Field

[0001] This invention relates to the field of ecological environment monitoring technology, and more specifically to a sample storage device for ecological environment monitoring. Background Technology

[0002] Environmental monitoring refers to the act of monitoring and measuring environmental quality by monitoring units. It is an important indicator that monitors and measures environmental quality to determine the degree of pollution and quality problems. Professionals collect and preserve samples outdoors, and then test and analyze the samples in the laboratory, which requires the use of sample storage devices.

[0003] Existing sample storage devices mainly consist of a storage box with a circular groove on the top surface. Several storage chambers are distributed within the groove, and a feeding mechanism is installed within the groove to add samples to each chamber. This feeding mechanism includes a movable plate movably positioned within the groove and a hopper slidably connected to the movable plate. The hopper has a funnel-shaped structure and guides the sample into the storage chamber. The inner wall of the groove has an annular groove, and both ends of the movable plate have connecting plates that slidably engage with the annular groove. The rotatable movable plate and the slidable hopper allow the hopper to move above each storage chamber for easy filling. The hopper can be moved to align with each storage chamber for independent filling. However, during filling, the operator must constantly focus on the highest liquid level in each storage chamber to prevent sample leakage and contamination of the storage box's inner wall, increasing the operator's attention span. Furthermore, manually adjusting the hopper's position to align with the storage chamber is not precise enough, easily leading to visual misalignment, affecting sample filling, and is also inefficient.

[0004] Furthermore, although multiple storage chambers are provided for independent sample loading, the single loading hopper, coupled with the lack of timely cleaning during continuous use, can easily lead to cross-contamination between different samples during loading, resulting in impure samples and affecting the accuracy of the test.

[0005] Therefore, there is an urgent need for a new sample storage device for ecological and environmental monitoring. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sample storage device for ecological environment monitoring to solve the problems existing in the background art.

[0007] The present invention provides the following technical solution: a sample storage device for ecological environment monitoring, comprising a storage box, the storage box comprising a stage and a base frame integrally formed therewith, side plates being movably connected between the columns of the base frame, the bottom surface of the side plates being connected to the outer edge of the top surface of the stage via a plurality of first springs, a position adjustment mechanism located at the top of the stage being installed on the inner side of the side plates, a top plate being movably connected to the top of the base frame via a hinge, a water supply mechanism being installed on the top surface of the top plate, a sample release tube being provided on the edge of the top plate adjacent to the water supply mechanism, and a controller for controlling the position adjustment mechanism being provided on the side wall of the stage;

[0008] The position adjustment mechanism includes a first lead screw, a second lead screw, and an injection assembly. Both ends of the first and second lead screws are movably connected to sliding plates. The first and second lead screws are threaded through the top and bottom of the injection assembly, respectively. The first and second lead screws are arranged perpendicularly to each other in space. The two ends of the first and second lead screws are fixedly connected to the output shaft of the forward and reverse motor and the balance block, respectively.

[0009] The injection assembly includes an infusion body, a collection tank fixedly installed on the top of the infusion body, a drainage assembly fixedly installed at the bottom of the collection tank, a guide channel opened at each of the four corners inside the infusion body, a guide pipe provided at one corner of the top of the collection tank, and a return groove adjacent to the guide pipe fixedly installed on the outer wall of the collection tank.

[0010] The water supply mechanism includes a water tank installed on the top surface of the roof slab and a flow-limiting component penetrating the surface of the roof slab;

[0011] The flow limiting assembly includes a medium-sized tube, a piston, a stop rod, and a second spring. The medium-sized tube is fixedly sleeved on the surface of the top plate. The inner cavity of the large inner diameter section of the medium-sized tube is connected to the piston through the second spring. The bottom end of the piston is integrally formed with a stop rod.

[0012] Preferably, the drainage assembly includes a waste drain pipe fixedly connected to the edge of the bottom surface of the infusion body and an electric push rod installed at the center of the bottom surface of the infusion body. A waterproof sleeve wrapped around the electric push rod is fixedly connected to the bottom surface of the infusion body, and a blocking plate blocking the bottom port of the waste drain pipe is fixedly connected to the movable end of the bottom of the electric push rod.

[0013] Preferably, more specifically, the top and bottom of the infusion body are threadedly connected to the first lead screw and the second lead screw respectively, and the bottom end of the reflux trough is connected to the inner cavity of the collection trough through a conduit.

[0014] Preferably, the surfaces at the connection points between the first and second lead screws and the sliding plate are set as smooth surfaces, and both ends of the first and second lead screws are connected to a forward and reverse motor and a balance block, and the forward and reverse motors and the balance block have equal masses.

[0015] Preferably, the guide tube is configured with an inclined slope angle from the edge to the middle, and a circular baffle is provided at the center of the guide tube. The baffle is connected to the edge of the top opening of the guide tube by a fixing rod. The guide tube has a cavity inside, and the diameter of the top opening of the guide tube is larger than the diameter of the bottom port of the medium tube.

[0016] Preferably, when the bottom end of the stop rod is not compressed, the second spring is at its original length. At this time, the piston closes the bottom outlet of the large inner diameter section of the medium tube and fits tightly with it. The cross-sectional diameter of the stop rod is smaller than the inner diameter of the bottom end of the medium tube, and the bottom end of the stop rod extends beyond the position of the bottom surface of the top plate.

[0017] Preferably, two side plates on opposite sides of the four side plates are completely identical. The top of one set of two side plates on opposite sides is provided with a sliding groove adapted to the sliding plate connected to both ends of the first lead screw, and the bottom of the other set of two side plates on opposite sides is provided with a sliding groove adapted to the sliding plate connected to both ends of the second lead screw.

[0018] Preferably, the interior of the stage has several sample storage tubes arranged in rows and columns and equidistantly inserted. The stage has two waste discharge channels directly below the sample placement tube and the flow limiting component. One channel is used to discharge excess sample that overflows during sample loading, and the other channel is used to discharge wastewater during the cleaning of the injection component cavity.

[0019] Preferably, the output of the controller is electrically connected to the control units of the two forward and reverse motors and the input of the electric push rod.

[0020] Preferably, the method of using the sample storage device for ecological environment monitoring is as follows:

[0021] S1. In the initial state, the injection component is located directly below the sample tube. The sample is poured into the guide tube along the top port of the sample tube. At this time, the drainage component is in a closed state until the inner cavity of the injection component is filled with the sample, at which point the sample loading stops.

[0022] S2. After the sample is injected into the inner cavity of the injection assembly, the total mass of the injection assembly plus the sample in its inner cavity increases, which in turn increases the total pressure on the top of the first spring from the side plate and the position adjustment mechanism. As a result, the first spring elastically contracts, and the four side plates drive the position adjustment mechanism connected to them and located inside them to move down as a whole under the action of the first spring. This causes the guide tube at the top of the injection assembly to detach from the bottom surface of the top plate, i.e., not to contact it. Further, the rotation of the first screw and the second screw adjusts the injection assembly to move to the top of a designated sample storage tube. After corresponding matching, the electric push rod is activated, and the movable end of the electric push rod drives the blocking plate connected to it to detach downward from the bottom port of the waste discharge tube. As a result, the sample stored in the collection tank, the guide channel and the inner cavity of the waste discharge tube falls from the bottom port of the opening into the sample storage tube that is aligned with it for sample storage.

[0023] S3. By turning on the two forward and reverse motors respectively, the output shafts of the two motors will drive the first lead screw and the second lead screw fixedly connected to them to rotate forward or in reverse. When the forward and reverse motor at the bottom is braked and drives the second lead screw to rotate, the injection assembly, the first lead screw that passes through its top side wall, the sliding plates that are movably sleeved at both ends of the first lead screw, and the forward and reverse motors and balance blocks located outside the two sliding plates and respectively connected to the two ends of the first lead screw will slide synchronously along the surface of the second lead screw and on the side wall of the side plate by relying on the sliding plates connected to both ends of the first lead screw.

[0024] S4. After the sample in the inner cavity of the injection assembly is injected into the sample storage tube, the total mass of the injection assembly plus the sample in the inner cavity decreases, thereby reducing the total pressure on the top of the first spring from the side plate and the position adjustment mechanism. As a result, the first spring elastically expands and returns to its original state. Then, the four side plates drive the position adjustment mechanism connected to them and located inside them to move upward as a whole under the action of the first spring, so that the guide tube located at the top of the injection assembly contacts the bottom surface of the top plate. Further, the rotation of the first screw and the second screw adjusts the injection assembly to move to the bottom surface of the flow limiting assembly. As the guide tube gradually approaches the flow limiting assembly, the guide tube gradually pushes the stop rod and piston towards the inner cavity of the medium tube and gradually compresses the second spring in the inner cavity of the medium tube. At this time, there is a gap on the inner wall edge of the medium tube for water to flow through. Then, the water flows through the gap to the guide tube, and then through the guide tube to the infusion body, the guide channel and the inner cavity of the drainage assembly in sequence for rinsing.

[0025] The technical effects and advantages of this invention are as follows:

[0026] 1. This invention, by incorporating a first spring, side plates, and a position adjustment mechanism, facilitates the rotation of a first lead screw and a second lead screw fixedly connected to it by activating two forward and reverse motors, respectively. When the forward and reverse motor at the bottom brakes and drives the second lead screw to rotate, the injection assembly, the first lead screw penetrating its top side wall, the sliding plates movably sleeved at both ends of the first lead screw, and the forward and reverse motors and balance blocks located outside the two sliding plates and respectively connected to the ends of the first lead screw will synchronously slide along the surface of the second lead screw and on the side wall of the side plate by relying on the sliding plates connected to the ends of the first lead screw. Similarly, when the forward and reverse motor at the top brakes and drives the first lead screw to rotate, the injection assembly, the second lead screw penetrating its bottom side wall, the sliding plates movably sleeved at both ends of the second lead screw, and the forward and reverse motors and balance blocks located outside the two sliding plates and respectively connected to the ends of the second lead screw will synchronously slide along the surface of the first lead screw and on the side wall of the side plate by relying on the sliding plates connected to the ends of the second lead screw. This allows for position adjustment of the injection assembly within the cavity enclosed by the four side plates, achieving precise position adjustment and improving efficiency.

[0027] 2. This invention, by incorporating an injection assembly, a first spring, side plates, and a sample storage tube, facilitates the following: After sample infusion into the inner cavity of the injection assembly, the total mass of the injection assembly plus the sample in the inner cavity increases, thereby increasing the total pressure on the top of the first spring from the side plates and the position adjustment mechanism. This causes the first spring to elastically contract, and the four side plates, driven by them, move the position adjustment mechanism located inside them downwards under the action of the first spring. This allows the guide tube at the top of the injection assembly to detach from the bottom surface of the top plate, i.e., it no longer contacts it. Furthermore, the rotation of the first and second lead screws adjusts the injection assembly to move to the top of a designated sample storage tube. After matching, the electric push rod is activated, and the movable end of the electric push rod drives the connected blocking plate to detach downwards from the bottom port of the waste discharge tube. The sample stored in the collection tank, guide channel, and inner cavity of the waste discharge tube then falls from the bottom port of the opening into the corresponding sample storage tube for storage. This achieves a one-to-one correspondence between the injection assembly and a designated sample storage tube, making it more accurate and avoiding deviation.

[0028] 3. This invention, by incorporating an injection assembly, a first spring, side plates, and a water supply mechanism, facilitates a reduction in the total mass of the injection assembly and the sample within the storage tube after the sample is injected into the sample storage tube. This reduces the total pressure on the top of the first spring from the side plates and the position adjustment mechanism, causing the first spring to elastically expand and return to its original position. Consequently, the four side plates drive the position adjustment mechanism, connected to them and located inside, to move upwards as a whole under the action of the first spring. This allows the guide tube at the top of the injection assembly to contact the bottom surface of the top plate. Furthermore, the rotation of the first and second screws adjusts the injection assembly to move to the bottom surface of the flow-limiting assembly. As the guide tube gradually approaches the flow-limiting assembly, it gradually pushes the stop rod and piston towards the inner cavity of the central tube, gradually compressing the second spring within the central tube. At this time, there is a gap on the inner wall edge of the central tube for water to flow through. Water flows through this gap to the guide tube and then sequentially to the infusion body, the guide channel, and the inner cavity of the drainage assembly for rinsing. This achieves timely and automatic cleaning after each use, ensuring the uniqueness of the next sample loading. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The sample storage device for ecological environment monitoring involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Reference Figure 1 and Figure 2 This invention provides a sample storage device for ecological environment monitoring, including a storage box 1. The storage box 1 includes a platform 101 and a base frame 102 integrally formed therewith. Side plates 3 are movably connected between the columns of the base frame 102. The bottom surface of the side plates 3 is connected to the outer edge of the top surface of the platform 101 by a plurality of first springs 2. A position adjustment mechanism 4 located on the top of the platform 101 is installed on the inner side of the side plates 3. A top plate 6 is movably connected to the top of the base frame 102 by a hinge. A water supply mechanism 7 is installed on the top surface of the top plate 6. A sample release tube 8 located adjacent to the water supply mechanism 7 is provided on the edge of the top plate 6. A controller 5 for controlling the position adjustment mechanism 4 is provided on the side wall of the platform 101.

[0040] In this embodiment, it should be specifically noted that there are four side plates 3, which are located in the four surfaces constructed by the four columns of the base frame 102. In addition, the two side walls of the four side plates 3 are movably connected to the columns of the base frame 102, so that the side plates 3 can move up and down without derailing.

[0041] Reference Figure 3-7The position adjustment mechanism 4 includes a first lead screw 401, a second lead screw 402, and an injection assembly 403. Both ends of the first lead screw 401 and the second lead screw 402 are connected to sliding plates 404 and are movably sleeved thereto. The first lead screw 401 and the second lead screw 402 are connected to the top and bottom of the injection assembly 403 and are threaded thereto. The first lead screw 401 and the second lead screw 402 are arranged perpendicularly to each other in space. The two ends of the first lead screw 401 and the second lead screw 402 are fixedly connected to the output shaft of the forward and reverse motor 405 and the balance block 406, respectively.

[0042] The injection assembly 403 includes an infusion body 4031, a collection tank 4032 fixedly installed on the top of the infusion body 4031, and a drainage assembly 4036 fixedly installed on the bottom of the collection tank 4032. More specifically, the top and bottom of the infusion body 4031 are threadedly connected to the first lead screw 401 and the second lead screw 402, respectively. Each of the four corners inside the infusion body 4031 is provided with a guide channel 4035. A guide pipe 4033 is provided at one corner of the top of the collection tank 4032. A return channel 4034 adjacent to the guide pipe 4033 is fixedly installed on the outer wall of the collection tank 4032. The bottom end of the return channel 4034 communicates with the inner cavity of the collection tank 4032 through a conduit.

[0043] The drainage assembly 4036 includes a waste drain pipe 40361 fixedly connected to the edge of the bottom surface of the infusion body 4031 and an electric push rod 40362 installed at the center of the bottom surface of the infusion body 4031. A waterproof sleeve 40364 is fixedly connected to the bottom surface of the infusion body 4031 and wraps around the electric push rod 40362 to prevent liquid from entering the electric push rod 40362 and affecting its use. A blocking plate 40363 is fixedly connected to the movable end of the bottom of the electric push rod 40362 to block the bottom port of the waste drain pipe 40361.

[0044] The water supply mechanism 7 includes a water tank 701 installed on the top surface of the top plate 6 and a flow limiting component 702 penetrating the surface of the top plate 6;

[0045] The flow limiting assembly 702 includes a central tube 7021, a piston 7022, a stop bar 7023, and a second spring 7024. The central tube 7021 is fixedly sleeved on the surface of the top plate 6. The inner cavity of the large inner diameter section of the central tube 7021 is connected to the piston 7022 through the second spring 7024. The bottom end of the piston 7022 is integrally formed with the stop bar 7023.

[0046] In this embodiment, it should be specifically noted that the surfaces at the connection points between the two ends of the first lead screw 401 and the second lead screw 402 and the sliding plate 404 are set as smooth surfaces in order to reduce friction between them and not affect the rotation of the first lead screw 401.

[0047] Both ends of the first lead screw 401 and the second lead screw 402 are connected to a forward and reverse motor 405 and a balance block 406, and the forward and reverse motor 405 and the balance block 406 have the same mass. The purpose is to maintain the balance at both ends of the first lead screw 401 and the second lead screw 402, improve the stability during movement, and also increase the balance of the pressure on the top of the first spring 2.

[0048] The guide tube 4033 is configured with an inclined slope angle from the edge to the middle, and a circular baffle is provided at the center of the guide tube 4033 to receive the baffle 7023. The baffle is connected to the edge of the top opening of the guide tube 4033 through a fixing rod. The guide tube 4033 has a cavity inside, and the diameter of the top opening of the guide tube 4033 is larger than the diameter of the bottom port of the medium tube 7021.

[0049] When the bottom end of the stop rod 7023 is not compressed, the second spring 7024 is at its original length. At this time, the piston 7022 closes the bottom outlet of the large inner diameter section of the medium tube 7021 and fits it tightly. The cross-sectional diameter of the stop rod 7023 is smaller than the inner diameter of the bottom end of the medium tube 7021, and the bottom end of the stop rod 7023 extends beyond the position of the bottom surface of the top plate 6.

[0050] Two of the four side plates 3 on opposite sides are completely identical. The top of one set of two side plates 3 on opposite sides is provided with a sliding groove that matches the sliding plate 404 connected to both ends of the first lead screw 401. The bottom of the other set of two side plates 3 on opposite sides is provided with a sliding groove that matches the sliding plate 404 connected to both ends of the second lead screw 402.

[0051] Reference Figure 8 The interior of the stage 101 has several sample storage tubes 9 arranged in rows and columns and equidistantly inserted. The stage 101 has two waste discharge troughs 103 located directly below the sample placement tube 8 and the flow limiting component 702. The outer waste discharge trough 103 is used to discharge excess sample that overflows during sample loading, and the inner waste discharge trough 103 is used to discharge wastewater during the cleaning of the inner cavity of the injection component 403.

[0052] The output of controller 5 is electrically connected to the control unit at the input of the two forward and reverse motors 405 and the electric push rod 40362.

[0053] Working principle of this invention:

[0054] S1. In the initial state, the injection component 403 is located directly below the sample tube 8. The sample is poured into the guide tube 4033 along the top port of the sample tube 8. At this time, the drain component 4036 is in a closed state until the inner cavity of the injection component 403 is filled with the sample, and then the sample loading stops.

[0055] S2. After the sample is infused into the cavity of the injection assembly 403, the total mass of the injection assembly 403 plus the sample in its cavity increases, thereby increasing the total pressure on the top of the first spring 2 from the side plate 3 and the position adjustment mechanism 4. Consequently, the first spring 2 elastically contracts, and the four side plates 3, connected to and located inside them, move downwards as a whole under the action of the first spring 2. This causes the guide tube 4033 located at the top of the injection assembly 403 to detach from the bottom surface of the top plate 6, i.e., it no longer contacts it. The injection assembly 403 is moved to the top of a designated sample storage tube 9 by rotating the first lead screw 401 and the second lead screw 402. After corresponding matching, the electric push rod 40362 is activated. The movable end of the electric push rod 40362 drives the blocking plate 40363 connected to it to detach downward from the bottom port of the waste discharge tube 40361. Then, the sample stored in the liquid collection tank 4032, the guide channel 4035 and the inner cavity of the waste discharge tube 40361 falls from the bottom port of the opening into the sample storage tube 9 that is aligned with it for sample storage.

[0056] S3. By activating the two forward and reverse motors 405 respectively, their output shafts drive the first lead screw 401 and the second lead screw 402 fixedly connected to them to rotate forward or in reverse. When the forward and reverse motor 405 located at the bottom brakes and drives the second lead screw 402 to rotate, the injection assembly 403, the first lead screw 401 passing through its top sidewall, the sliding plates 404 movably sleeved at both ends of the first lead screw 401, and the forward and reverse motors 405 and the balance block 406 located outside the two sliding plates 404 and respectively connected to the two ends of the first lead screw 401 will synchronously move along the surface of the second lead screw 402 and rely on the sliding plates 404 connected to the two ends of the first lead screw 401. Plate 404 slides on the side wall of side plate 3. Similarly, when the forward and reverse motor 405 at the top brakes and drives the first lead screw 401 to rotate, the injection assembly 403, the second lead screw 402 passing through its bottom side wall, the sliding plate 404 movably sleeved at both ends of the second lead screw 402, and the forward and reverse motor 405 and balance block 406 located outside the two sliding plates 404 and respectively connected to the two ends of the second lead screw 402 will synchronously slide along the surface of the first lead screw 401 and rely on the sliding plate 404 connected to both ends of the second lead screw 402 on the side wall of side plate 3 to adjust the position of the injection assembly 403 in the cavity enclosed by the four side plates 3.

[0057] S4. After the sample is injected into the sample storage tube 9 from the inner cavity of the injection assembly 403, the total mass of the injection assembly 403 plus the sample in the inner cavity decreases, thereby reducing the total pressure from the side plate 3 and the position adjustment mechanism 4 on the top of the first spring 2. Consequently, the first spring 2 elastically expands and returns to its original position. Then, the four side plates 3 drive the position adjustment mechanism 4 connected to them and located inside them to move upward as a whole under the action of the first spring 2, so that the guide tube 4033 located at the top of the injection assembly 403 contacts the bottom surface of the top plate 6. The injection is further adjusted by rotating the first lead screw 401 and the second lead screw 402. As component 403 moves to the bottom of flow limiting component 702, and as the guide tube 4033 gradually approaches the flow limiting component 702, the guide tube 4033 gradually pushes the baffle 7023 and piston 7022 toward the inner cavity of the central tube 7021 and gradually compresses the second spring 7024 in the inner cavity of the central tube 7021. At this time, there is a gap on the inner wall edge of the central tube 7021 for water to flow through, and then the water flows through the gap to the guide tube 4033, and then through the guide tube 4033 to the infusion body 4031, the guide channel 4035 and the inner cavity of the drainage component 4036 for flushing.

[0058] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, in accordance with the technical plan and improved concept of the present invention, should be included under the protection of the present invention.

10. A sample storage device for ecological environment monitoring according to claim 1, characterized in that: The method of using the sample storage device for ecological environment monitoring is as follows: S1. In the initial state, the injection assembly (403) is located directly below the sample tube (8). The sample is injected into the guide tube (4033) along the top port of the sample tube (8). At this time, the drain assembly (4036) is in a closed state until the inner cavity of the injection assembly (403) is filled with the sample, and then the sample loading stops. S2. After the sample is infused into the cavity of the injection assembly (403), the total mass of the injection assembly (403) plus the sample in its cavity increases, thereby increasing the total pressure on the top of the first spring (2) from the side plate (3) and the position adjustment mechanism (4). Consequently, the first spring (2) undergoes elastic contraction, and the four side plates (3) drive the position adjustment mechanism (4) connected to them and located inside them to move downward as a whole under the action of the first spring (2), so that the guide tube (4033) located at the top of the injection assembly (403) detaches from the bottom surface of the top plate (6), that is, it does not contact it, and further... The injection assembly (403) is moved to the top of a designated sample storage tube (9) by rotating the first lead screw (401) and the second lead screw (402). After matching, the electric push rod (40362) is turned on. The moving end of the electric push rod (40362) drives the blocking plate (40363) connected to it to detach downward from the bottom port of the waste discharge tube (40361). Then, the sample stored in the inner cavity of the liquid collection tank (4032), the guide channel (4035) and the waste discharge tube (40361) falls from the bottom port of the opening into the sample storage tube (9) that is aligned with it for sample storage. S3. By turning on two forward and reverse motors (405) respectively, the output shafts of the two motors will drive the first lead screw (401) and the second lead screw (402) fixedly connected to them to rotate forward or in reverse. When the forward and reverse motor (405) at the bottom is braked and drives the second lead screw (402) to rotate, the injection assembly (403), the first lead screw (401) that passes through its top side wall, the sliding plate (404) that is movably sleeved on both ends of the first lead screw (401), and the forward and reverse motors (405) and the balance block (406) located outside the two sliding plates (404) and connected to the two ends of the first lead screw (401) will slide synchronously along the surface of the second lead screw (402) and on the side wall of the side plate (3) by relying on the sliding plates (404) connected to both ends of the first lead screw (401). S4. After the sample in the inner cavity of the injection assembly (403) is injected into the sample storage tube (9), the total mass of the injection assembly (403) plus the sample in the inner cavity decreases, thereby reducing the total pressure on the top of the first spring (2) from the side plate (3) and the position adjustment mechanism (4). As a result, the first spring (2) elastically expands and returns to its original state. Then, the four side plates (3) drive the position adjustment mechanism (4) connected to them and located inside them to move upward as a whole under the action of the first spring (2), so that the guide tube (4033) located at the top of the injection assembly (403) contacts the bottom surface of the top plate (6), and further through the first lead screw ( The rotation of the second lead screw (401) and the second lead screw (402) adjusts the injection assembly (403) to move to the bottom surface of the flow limiting assembly (702). As the guide tube (4033) gradually approaches the flow limiting assembly (702), the guide tube (4033) gradually pushes the stop rod (7023) and piston (7022) towards the inner cavity of the central tube (7021) and gradually compresses the second spring (7024) in the inner cavity of the central tube (7021). At this time, there is a gap on the inner wall edge of the central tube (7021) for water to flow through. The water then flows through this gap to the guide tube (4033) and then through the guide tube (4033). It is sequentially delivered to the inner cavities of the infusion body (4031), the diversion channel (4035), and the drainage assembly (4036). Rinse it.
