Description

Technical Field

[0001] This application relates to the field of laboratory instrument cleaning equipment technology, and in particular to a test tube cleaning device. Background Technology

[0002] In the acid dissolution experiment of marine sediments, the cleaning quality of the acid dissolution mother liquor test tubes after use directly affects the accuracy and reliability of the experimental results. Therefore, the cleaning of the acid dissolution mother liquor test tubes after use is of utmost importance.

[0003] Currently, most laboratories still use the traditional method of manually cleaning each test tube individually for cleaning test tubes containing acid-soluble mother liquor from marine sediments. This method is not only slow and inefficient, but also makes it difficult to guarantee a high degree of consistency in the cleaning quality of each test tube due to the inherent variability in manual operation. Utility Model Content

[0004] This application provides a test tube cleaning device to solve the problems of slow cleaning speed, low cleaning efficiency, and inconsistent cleaning quality that exist in the prior art when cleaning multiple test tubes one by one manually.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a test tube cleaning device, including: a connecting frame with a liquid injection channel; multiple brush heads, each brush head connected to the connecting frame and arranged at intervals; wherein, each brush head includes a brush body and a liquid injection tube, the liquid injection tube passing through the center of the brush body and communicating with the liquid injection channel.

[0007] As an optional implementation, it also includes: a handle, movably connected to the side of the connector away from the brush head, to adjust the angle between the connector and the handle.

[0008] As an optional implementation, a liquid injection switch is provided on the handle, which is used to control the opening and closing of the liquid injection channel.

[0009] As an alternative implementation, the brush body is a sponge and is designed to fit tightly against the inner wall of the test tube.

[0010] As an alternative implementation, the brush body is cylindrical; and the height of the brush body is greater than or equal to the depth of the test tube.

[0011] As an alternative implementation, the bottom end of the injection tube is flush with the bottom end of the brush body.

[0012] As an alternative implementation, the outer wall of the brush body is provided with protrusions.

[0013] As an optional implementation, the brush heads are arranged in a rectangular array.

[0014] As an optional implementation, the row spacing between any two adjacent rows of brush heads is equal, and / or the column spacing between any two adjacent columns of brush heads is equal.

[0015] As an optional implementation, it also includes: a detergent adding device, which contains detergent and is connected to the injection channel.

[0016] The test tube cleaning apparatus provided in this application includes a connecting frame and multiple brush heads. Each brush head is connected to the connecting frame and arranged at intervals. The connecting frame is provided with a liquid injection channel. Each brush head includes a brush body and a liquid injection tube, with the liquid injection tube passing through the center of the brush body and communicating with the liquid injection channel.

[0017] Because the connecting rack has multiple brush heads, this test tube cleaning device allows for the simultaneous cleaning of multiple test tubes, improving cleaning efficiency while ensuring consistent cleaning quality across all tubes. The spacing between the brush heads prevents interference and ensures suitability for cleaning test tubes on a rack.

[0018] The connecting frame is equipped with a liquid injection channel, and the brush head has a brush body and a liquid injection tube inserted through the center of the brush body. This allows the cleaning solution to flow through the liquid injection channel to the liquid injection tube in the center of the brush body, and finally into each test tube to be cleaned, cleaning the inner wall of the test tube together with the brush body. Thus, water injection can be performed simultaneously during the cleaning process, further enhancing the cleaning effect and ensuring thorough cleaning. Attached Figure Description

[0027] Acid dissolution testing of marine sediments is a method used to analyze the chemical composition of marine sediments. This experiment provides specific information about the metallic elements, nutrients, or pollutants in marine sediments, which is of great significance for studying marine geology, environmental monitoring, and assessing the impact of human activities on marine ecosystems. Acid dissolution testing typically involves steps such as sample collection, sample preparation, acid dissolution treatment, filtration and separation of the dissolved mixture, and chemical analysis of the solution.

[0028] In acid dissolution experiments on marine sediments, it is crucial to thoroughly clean the test tubes containing the used acid dissolution mother solution for the following reasons:

[0029] (1) The acid solution remaining in the test tube may contain components of the previous sample. If not cleaned thoroughly, it may contaminate subsequent samples, causing cross-contamination and resulting in inaccurate experimental results.

[0030] (2) Incomplete cleaning can lead to increased background values ​​or false positive results, thus affecting the accuracy and reliability of the data.

[0031] (3) Acidic solutions are corrosive to glass and other materials. If not cleaned in time, they may damage test tubes and other experimental equipment and shorten their service life. In addition, residual acidic solutions may pose a safety hazard to laboratory personnel.

[0032] (4) In scientific experiments, standardized operating procedures are key to ensuring the reproducibility of experiments and the consistency of results. Failure to thoroughly clean test tubes or inconsistent cleaning quality among multiple test tubes will affect the standardization of experiments.

[0033] Therefore, strictly following the cleaning procedure is a key step to ensure the success of acid dissolution experiments on marine sediments.

[0034] Currently, most laboratories still use the traditional method of manually cleaning each test tube individually for cleaning test tubes containing acid-soluble mother liquor from marine sediments. However, this method is not only inefficient, but also makes it difficult to ensure a high degree of consistency in the cleaning quality of each test tube due to variations in manual operation.

[0035] In particular, when faced with the task of cleaning multiple test tubes at once (such as 40 or 60 tubes), the drawbacks of manual cleaning are magnified. Not only does it consume a significant amount of manpower and time, but it is also highly susceptible to incomplete cleaning, leaving acid-soluble mother liquor residue on the inner walls of the test tubes. These residues are highly likely to interfere with subsequent experiments, leading to biased results and seriously affecting the credibility of research conclusions.

[0036] In existing technologies, some conventional cleaning brushes are typically only suitable for cleaning single test tubes and cannot meet the needs of large-scale batch cleaning. In addition, a few cleaning devices can clean a small number of test tubes at the same time, but they generally suffer from problems such as complex structure, high purchase and maintenance costs, and poor operational flexibility, making them difficult to meet the actual use needs and budget constraints of general laboratories.

[0037] To overcome the deficiencies in the prior art, this application provides a test tube cleaning device, which includes a connecting frame and multiple brush heads. Each brush head is connected to the connecting frame and arranged at intervals. The connecting frame is provided with a liquid injection channel. Each brush head includes a brush body and a liquid injection tube, which passes through the center of the brush body and is connected to the liquid injection channel.

[0038] Because the connecting rack has multiple brush heads, this test tube cleaning device allows for the simultaneous cleaning of multiple test tubes, improving cleaning efficiency while ensuring consistent cleaning quality across all tubes. The spacing between the brush heads prevents interference and ensures suitability for cleaning test tubes on a rack.

[0039] The connecting frame is equipped with a liquid injection channel, and the brush head has a brush body and a liquid injection tube inserted through the center of the brush body. This allows the cleaning solution to flow through the liquid injection channel to the liquid injection tube in the center of the brush body, and finally into each test tube to be cleaned, cleaning the inner wall of the test tube together with the brush body. Thus, water injection can be performed simultaneously during the cleaning process, further enhancing the cleaning effect and ensuring thorough cleaning.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] Figure 1 This is a front view of a test tube cleaning apparatus provided in an embodiment of this application. Figure 2 for Figure 1 A bottom view of the test tube cleaning apparatus. (Refer to...) Figure 1 and Figure 2 As shown, this application provides a test tube cleaning device. The test tube cleaning device includes a connecting frame 200 and a plurality of brush heads 100. Each brush head 100 is connected to one side of the connecting frame 200, and the brush heads 100 are arranged at intervals.

[0042] The connecting frame 200 is provided with a liquid injection channel (not shown) through which cleaning fluid can pass. The brush head 100 includes a brush body 110 and a liquid injection tube 120, which passes through the center of the brush body 110 and is connected to the liquid injection channel. In this way, cleaning fluid can flow into the test tube to be cleaned through the liquid injection tube 120 on the brush head 100.

[0043] In some embodiments, the injection channel can be an internal flow channel directly formed on the connecting frame 200. For example, for any combination of brush heads 100, the outlets of the internal flow channel can be configured one-to-one with the number and position of the injection tubes 120 in each brush head 100. Alternatively, to improve the compatibility of the connecting frame 200 with different combinations of brush heads 100, multiple outlets of the internal flow channel can be arrayed, with small intervals between each outlet, and densely arranged on the connecting frame 200. The operator can select the corresponding flow channel outlet according to the specific number and layout of the brush heads 100, connect the injection tubes 120 in the brush head 100 to the corresponding flow channel outlet, and at the same time, block any excess flow channel outlets to prevent cleaning fluid from overflowing.

[0044] In other embodiments, the connecting frame 200 may be provided with a plate 210 and a liquid inlet pipe 220 (see reference). Figure 3 (As shown). The plate 210 does not have internal flow channels, and the inlet pipe 220 is in the form of a conduit. The inlet pipe 220 is mounted on the plate 210 and forms a connecting frame 200 with the plate 210. In this case, the injection channel refers to the channel inside the inlet pipe 220 located on the plate 210, and the outlet of the inlet pipe 220 corresponds one-to-one with the number and position of the injection pipes 120 in each brush head 100.

[0045] It should be noted that the cleaning solution can be water or a mixture of water and other detergents; no specific limitations are made here.

[0046] It is understood that the brush heads 100 are arranged at intervals on the connecting frame 200, and the brush heads 100 can be arranged in any shape such as circle, rectangle, triangle, trapezoid, etc. The specific arrangement can be set according to the shape of the test tube rack to which the cleaning device is applicable, and the specific arrangement of each brush head 100 is not limited here.

[0047] Because the connecting rack 200 is connected to multiple brush heads 100, when using this test tube cleaning device, multiple test tubes can be cleaned simultaneously using the multiple brush heads 100, which improves cleaning efficiency and ensures the consistency of cleaning quality for each test tube as much as possible. The spacing between the multiple brush heads 100 ensures that they do not interfere with each other and is suitable for cleaning test tubes on the test tube rack.

[0048] The connecting frame 200 is equipped with a liquid injection channel, and the brush head 100 is equipped with a brush body 110 and a liquid injection tube 120 passing through the center of the brush body 110. This allows the cleaning solution to flow through the liquid injection channel to the liquid injection tube 120 in the center of the brush body 110, and ultimately into each test tube to be cleaned, working together with the brush body 110 to clean the inner wall of the test tube. Thus, the liquid injection function can be simultaneously implemented during the cleaning process, further enhancing the cleaning effect, ensuring thorough cleaning, and improving the cleanliness of the test tubes.

[0049] In this way, a batch of test tubes can be cleaned simultaneously in one operation using the test tube cleaning device. Compared with the traditional method of cleaning test tubes one by one manually, the cleaning efficiency is improved, saving manpower and time costs and improving the efficiency of laboratory work.

[0050] In some embodiments, the injection tube 120 may be made of a flexible and bendable plastic material so that the test tube cleaning device can flexibly adapt to the cleaning needs of test tubes of different heights and tilt angles, ensuring that the brush body 110 can be smoothly and accurately inserted into the test tube and achieve full and close contact with the inner wall of the test tube.

[0051] In some embodiments, the wall of the injection tube 120 may be provided with multiple water spray holes along the height direction of the injection tube 120, so that the cleaning liquid can flow out from different heights to wet the externally connected brush body 110, thereby enhancing the cleaning effect of the test tube.

[0052] In some embodiments, a nozzle (not shown) may be connected to the bottom of the injection tube 120. The nozzle is provided with multiple spray holes. When the cleaning fluid passes through the spray holes, the flow channel narrows sharply, thereby increasing the flow rate of the cleaning fluid and enhancing the rinsing effect of the cleaning fluid on the inside of the test tube.

[0053] Continue to refer to Figure 1 As shown, the brush body 110 is wrapped around the injection tube 120 and fixedly connected to it. Specifically, the brush body 110 has a through hole in its center for the injection tube 120 to pass through, and the brush body 110 can be detachably connected to the injection tube 120, for example, by bonding, threading, or snap-fitting. Thus, when the brush body 110 is damaged, dirty, or has been used for an extended period, it can be replaced promptly.

[0054] In one implementation, the brush body 110 can be a sponge. Furthermore, the brush body 110 can be used to fit closely to the inner wall of the test tube. Specifically, a high-quality sponge material with a soft texture and strong adsorption properties can be selected to make the brush body 110. Inserting the brush body 110 into the test tube allows for effective cleaning of the test tube through friction between the sponge and the inner wall of the test tube.

[0055] For example, the brush body 110 may be cylindrical, such as a cylinder or a prism. The height of the brush body 110 is greater than or equal to the depth of the test tube. Furthermore, the diameter of the brush body 110 may be greater than or equal to the diameter of the test tube.

[0056] Specifically, the brush head 100 can be cylindrical to match the shape of the test tube, with a height equal to or greater than the depth of the test tube, to ensure that it can fully cover any corner of the inner wall of the test tube during the cleaning process. When the height of the brush body 110 is greater than the depth of the test tube, the brush head 100 extending beyond the opening of the test tube can clean stains or residues at the opening of the test tube, improving the cleaning quality.

[0057] In one implementation, the bottom end of the injection tube 120 is flush with the bottom end of the brush body 110. This arrangement avoids the brush body 110 failing to contact the inner wall of the test tube due to the injection tube 120 abutting against the bottom, thus preventing a cleaning blind spot. It also prevents the injected cleaning solution from being absorbed by the brush body 110 and failing to flow into the lower part of the test tube due to the injection tube 120 being too short.

[0058] To further improve cleaning quality and effect, in some embodiments, the brush body 110 is also provided with protrusions 1101. The protrusions 1101 are distributed on the outer wall of the brush body 110 and can fit tightly against the inner wall of the test tube. For example, multiple protrusions 1101 can be provided and evenly arranged around the outer wall surface of the brush body 110.

[0059] In this way, the friction between the brush body 110 and the inner wall of the test tube can be effectively increased by the protrusion 1101, thereby efficiently removing stubborn acid-soluble mother liquor residues adhering to the test tube wall.

[0060] like Figure 2 As shown, in some embodiments, the brush heads 100 can be arranged in a rectangular array to match the shape of the test tubes placed on the test tube rack. Multiple brush heads 100 can be distributed in M ​​rows and N columns, where N and M are natural numbers greater than 1. For example, multiple brush heads 100 can be arranged at intervals in the form of 4 rows and 10 columns, 5 rows and 8 columns, 5 rows and 10 columns, 6 rows and 10 columns, 5 rows and 12 columns, etc., to accommodate the cleaning of test tubes placed on test tube racks of different sizes.

[0061] Furthermore, the row spacing between any two adjacent rows of brush heads 100 can be equal, or the column spacing between any two adjacent columns of brush heads 100 can be equal, or both the row spacing between any two adjacent rows of brush heads 100 and the column spacing between any two adjacent columns of brush heads 100 can be equal. This configuration facilitates processing and provides a higher degree of compatibility with test tube rack arrangements.

[0062] Continue to refer to Figure 1 The test tube cleaning device also includes a handle 300. The handle 300 is located on the side of the connecting frame 200 away from the brush head 100. Furthermore, the handle 300 is movably connected to the connecting frame 200, allowing the angle between them to be adjustable. This configuration allows for cleaning of test tubes in different orientations and angles by adjusting the angle between the connecting frame 200 and the handle 300.

[0063] For example, the top surface of the connecting frame 200 may be provided with a hinge seat 240, and the handle 300 may rotate 180° relative to the hinge seat 240, thereby achieving an adjustable angle between the handle 300 and the connecting frame 200. This configuration also allows for a detachable connection between the handle 300 and the connecting frame 200, facilitating the replacement and maintenance of the brush head 100 assembly.

[0064] Specifically, the hinge seat 240 can be positioned at the middle of the length of the connecting frame 200 and symmetrically arranged at both ends of the width of the connecting frame 200. This allows for flexible adjustment of the relative position between the handle 300 and the connecting frame 200, while also facilitating operation and force application by personnel.

[0065] In some embodiments, a liquid injection switch may be provided on the handle 300. This liquid injection switch can be used to control the opening and closing of the liquid injection channel. For example, the liquid injection switch may be configured as a proximity switch; when the switch is triggered, an electrical signal can be sent to control the opening and closing of the valve located on the liquid injection channel, thereby achieving control of the liquid injection channel. Alternatively, triggering the switch can also actuate a mechanical structure (such as a piston or lever) connected to the valve, thereby opening the valve.

[0066] This setup allows operators to flexibly adjust cleaning strategies according to actual needs during the cleaning process, making the cleaning operation more convenient and efficient.

[0067] The handle 300 may also have multiple grooves, which can be arc-shaped and conform to the shape of the fingers. When gripping, the operator's fingers can fit into the grooves for a stable grip. Furthermore, the injection switch can be located on the grooves to make the injection switch button easy to press.

[0068] In one embodiment, the test tube cleaning apparatus also includes a washing solution adding device. The washing solution adding device contains washing solution that can dissolve the acid-soluble mother liquor inside. Furthermore, the washing solution adding device can be connected to the injection channel, allowing the washing solution to flow into the injection tube 120 via the injection channel and then into the test tube, further enhancing the cleaning effect.

[0069] It should be noted that the washing solution can be a weak acid solution or deionized water, as long as it can dissolve the acid-soluble mother liquor and does not affect the normal operation of the injection channel, injection tube 120, and test tube. No specific restrictions are made here.

[0070] In some embodiments, the brush head 100 is fixedly connected to the injection channel via the injection tube 120. This allows for a stable connection between multiple brush heads 100 and the connecting frame 200, and enables the cleaning fluid in the injection channel to flow normally into the injection tube 120.

[0071] Figure 3 A front view of another test tube cleaning apparatus provided in an embodiment of this application. (Refer to...) Figure 3 As shown, the connecting frame 200 includes a plate 210 and a liquid inlet pipe 220. The liquid inlet pipe 220 is fitted onto the side of the plate 210 facing the brush head 100 and is connected to the injection pipe 120. The liquid inlet pipe 220 forms an injection channel, allowing the cleaning fluid to enter the injection pipe 120 through the liquid inlet pipe 220.

[0072] Specifically, the inlet pipe 220 is provided with multiple outlet ends 222, which correspond one-to-one with and are fixedly connected to the top ends of multiple injection pipes 120 to ensure smooth flow of the cleaning fluid. It should be noted that the fixed connection between the multiple outlet ends 222 and the multiple injection pipes 120 can be a threaded connection, a flange connection, a compression fitting connection, etc., and no specific limitation is made here.

[0073] The liquid inlet pipe 220 is also provided with an inlet end 221, which can be connected to a cleaning fluid supply device to allow the cleaning fluid to flow in. For example, the inlet end 221 can be connected to a faucet or water tank through a connecting pipe, so that water can flow into the liquid inlet pipe 220.

[0074] In some embodiments, a cap 230 may also be provided at the top of the inlet end 221. When the test tube cleaning device is not working, the cap 230 can be used to seal the inlet end 221 to prevent other impurities in the environment from entering the liquid inlet pipe 220.

[0075] For example, a groove (not shown) may be provided on the plate 210, the groove being adapted to the shape of the liquid inlet pipe 220. The liquid inlet pipe 220 is partially placed in the groove, and the liquid inlet pipe 220 is fixedly connected to the plate 210. For example, by adhesive bonding, snap-fitting, or clamping connection.

[0076] This configuration allows for a stable connection between the injection tube 120 and the inlet pipe 220, and reduces the space occupied by the inlet pipe 220, making the overall structure of the test tube cleaning device more compact.

[0077] The test tube cleaning device provided in this application is used as follows:

[0078] (1) Assembly preparation: First, securely connect multiple brush heads 100 to the connecting frame 200 to ensure the firmness and stability of the connection parts, so as to ensure that multiple brush heads 100 will not loosen or fall off during the cleaning process.

[0079] Subsequently, the connecting frame 200 and the handle 300 are assembled and connected, and the bending angle of the connecting rod is flexibly adjusted according to the actual placement of the test tubes to be cleaned, so as to ensure that the brush head 100 can be smoothly inserted into the test tubes.

[0080] Finally, properly connect the external cleaning fluid to the injection channel and injection pipe 120, and conduct a fluid flow test to ensure that the fluid can flow smoothly through the thin tube, thus making full preparations for subsequent cleaning work.

[0081] (2) Cleaning operation: Arrange multiple (e.g., 40 or 60) test tubes of marine sediment acid dissolution mother liquor neatly on the appropriate test tube rack. Precisely align the brush head 100 with the mouth of each test tube, and then gently apply downward pressure to allow the brush head 100 to slowly and steadily insert into the test tube. After the brush head 100 is fully inserted into the test tube, press the liquid injection switch on the handle 300 to start the liquid injection function.

[0082] At this point, the operator can hold the handle 300 and move the cleaning brush up and down at a uniform speed. Using the sponge material of the brush head 100, the surface protrusions 1101, and the flushing effect of the liquid flow, the inner wall of the test tube can be thoroughly and meticulously cleaned.

[0083] (3) Post-cleaning treatment: After the cleaning work is completed, release the liquid injection switch on the handle 300 to stop the liquid spraying. Carefully remove the test tube cleaning device from the test tube and rinse the brush head 100 assembly repeatedly with cleaning solution to thoroughly remove any residual acid-soluble mother liquor. During the cleaning process, carefully check the condition of each brush head 100. If any brush head 100 is found to be damaged or severely worn, the brush head 100 assembly can be replaced in time by disassembling the connection between the liquid injection tube 120 and the liquid injection channel to ensure that the cleaning brush always maintains a good working condition.

[0084] The test tube cleaning device provided in this application has the following beneficial effects:

[0085] 1. High-efficiency cleaning: Thanks to its unique design, this test tube cleaning device can clean 60 test tubes at the same time in one operation. Compared with the traditional manual cleaning method, the cleaning efficiency is increased exponentially, which greatly saves manpower and time costs and significantly improves the efficiency of laboratory work.

[0086] 2. Thorough Cleaning: The soft and highly absorbent sponge material used in the brush head 100, combined with the tiny raised bumps 1101 on its surface, effectively removes various acid-soluble mother liquor residues from the inner walls of test tubes. Simultaneously, the innovative function of spraying water while cleaning further ensures the depth and thoroughness of the cleaning process, minimizing the potential impact of residual substances on subsequent experiments.

[0087] 3. Flexible and Convenient: The elasticity and flexibility of the injection tube 120 allow the brush head 100 to easily handle test tubes in different positions. The detachable connection design between the handle 300 and the connecting bracket 200 facilitates parts replacement. Furthermore, the injection switch on the handle 300 allows operators to flexibly adjust the cleaning strategy according to actual needs during the cleaning process, making the cleaning operation more convenient and efficient.
