Description

Technical Field

[0001] This utility model relates to the field of laboratory auxiliary equipment technology, and in particular to a cleaning device for laboratory utensils. Background Technology

[0002] Glassware, with its chemical stability, high temperature resistance, and high transparency, is an indispensable tool in various experimental operations and is widely used in laboratory analysis and testing. However, used glassware often retains various chemical reagents, samples, and other contaminants. Failure to thoroughly clean it can not only affect the accuracy of subsequent experimental results but also lead to cross-contamination and experimental failure.

[0003] In related technologies, traditional laboratory glassware cleaning mainly relies on manual operation. Operators use tools such as brushes and detergents to clean individual glassware one by one through steps such as soaking and brushing; or they use ultrasonic cleaners to utilize the cavitation effect generated by ultrasound in liquids, which causes liquid molecules to vibrate violently and impact the surface of glassware, thereby removing dirt.

[0004] Among the traditional cleaning methods mentioned above, manual cleaning is extremely inefficient. When laboratories need to process a large number of glassware, manual cleaning is time-consuming and labor-intensive, making it difficult to meet the ever-increasing experimental demands. While ultrasonic cleaners offer better cleaning results, they suffer from cross-contamination when cleaning multiple pieces of glassware. Furthermore, cleaning by category still results in long cleaning times and high equipment costs. Utility Model Content

[0005] This utility model provides a cleaning device for laboratory glassware, which solves the technical problems of low cleaning efficiency and high cost caused by the shortcomings of existing laboratory glassware cleaning methods. The technical solution is as follows: This utility model provides a cleaning device for laboratory glassware, including: a cleaning tank and a spray washing assembly. The cleaning tank is equipped with a water tank that communicates with the top, and the cleaning tank is equipped with a water inlet and a water outlet that communicate with the water tank. The spray washing assembly is installed in the water tank and multiple sets are arranged in an array. Each set of the spray washing assembly includes a mounting bracket and a sprayer. The mounting bracket includes a horizontally arranged mounting surface. The sprayer is fixedly connected to the mounting surface and has a cylindrical nozzle arranged facing the opening of the water tank. A brush is provided on the outer peripheral wall of the cylindrical nozzle. The sprayer is connected to the water inlet.

[0006] Optionally, the sprayer is connected to the mounting bracket via a mounting cylinder. A smaller diameter mounting port is coaxially connected to the top of the mounting cylinder. The mounting cylinder and the mounting port are connected via a tapered tapered section. A spring is coaxially arranged inside the mounting cylinder. One end of the spring is fixedly connected to the side wall at the bottom of the mounting cylinder, and the other end is connected to a small ball with a diameter larger than the inner diameter of the mounting port. The cylindrical nozzle is telescopically installed inside the mounting port. A grid hole is provided on the side wall at the bottom of the cylindrical nozzle. The mounting cylinder is connected to the water inlet.

[0007] Optionally, a circular support plate is provided on the outer side wall of the cylindrical nozzle, extending radially outward.

[0008] Optionally, the circular support plate has multiple water passage holes arranged in a circular array.

[0009] Optionally, the brush is detachably mounted on the cylindrical nozzle section above the circular support plate.

[0010] Optionally, the mounting brackets of multiple sets of the spray washing components are integrally connected and share the same mounting surface, and multiple drainage holes are provided through the mounting surface.

[0011] Optionally, a sprayer mounting hole is provided on the mounting surface, and the sprayer is threadedly connected to the sprayer mounting hole.

[0012] Optionally, it also includes a cover plate, which is disposed over the water tank and slidably connected to the side wall of the water tank.

[0013] Optionally, an elastic limiting member is provided between the cover plate and the cylindrical nozzle.

[0014] Optionally, a handle is provided on the top of the cover plate.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: When cleaning laboratory glassware, such as test tubes and beakers, is required, the glassware is inverted and fitted onto a cylindrical nozzle with its opening aligned with the spray nozzle. The brushes on the side of the nozzle then contact the inner wall of the glassware. Connecting to an external water supply line via the inlet allows high-pressure water to flow through the nozzle, rinsing the inner wall of the glassware from the inside. This, combined with the brush bristles, automatically cleans the glassware without manual intervention. Wastewater flows under gravity from the inner wall of the glassware and falls to the bottom of a tank, then drains out. By using multiple spray units with a flexible hose structure with multiple branches, the inlet can be independently connected to multiple sprayers for simultaneous water supply, enabling the cleaning of multiple glassware items at the same time. Because the glassware is placed upside down on top of the cylindrical nozzle, the water sprayed from the nozzle is blocked by the side walls of the glassware and discharged from the bottom, preventing splashing onto other glassware being cleaned. This effectively avoids cross-contamination while achieving simultaneous cleaning. It effectively solves the technical problems of low cleaning efficiency and high cost caused by the shortcomings of existing laboratory glassware cleaning methods. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Figure 1 This is a schematic diagram of the structure of a cleaning device for laboratory utensils provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of the cleaning device for laboratory utensils provided in this embodiment of the present invention after removing the cover plate and the elastic limiting member; Figure 3 This is a schematic diagram of the spray washer in the closed state according to an embodiment of the present invention; Figure 4 This is a schematic diagram of the spray washer in the open state according to an embodiment of the present invention; Figure 5 This is a three-dimensional structural diagram of the spray cleaner provided in this embodiment of the utility model; Figure 6 This is a schematic diagram of the structure of the mounting bracket provided in an embodiment of the present utility model; Figure 7 This is a structural schematic diagram of the elastic limiting member provided in an embodiment of this utility model. Figures 1 to 7 As shown, this utility model embodiment provides a cleaning device for laboratory glassware, including: a cleaning tank 1 and a spray washing assembly 2.

[0021] The cleaning tank 1 is equipped with a water tank 11 that is connected to the top, and the cleaning tank 1 is equipped with a water inlet 12 and a drain outlet 13 that are connected to the water tank 11.

[0022] The spray washing assembly 2 is installed in the water tank 11 and multiple sets are arranged in an array. Each set of spray washing assembly 2 includes a mounting bracket 21 and a sprayer 22. The mounting bracket 21 includes a horizontally arranged mounting surface 211. The sprayer 22 is fixedly connected to the mounting surface 211 and has a cylindrical nozzle 221 arranged facing the opening of the water tank 11. A brush 222 is provided on the outer peripheral wall of the cylindrical nozzle 221. The sprayer 22 is connected to the water inlet 12.

[0023] In this embodiment of the invention, when cleaning glassware such as test tubes and beakers in the laboratory is required, the glassware is inverted and fitted onto the cylindrical nozzle 221 with its opening aligned with the sprayer 22. At this time, the brush 222 on the side wall of the cylindrical nozzle 221 contacts the inner wall of the glassware. An external water supply line is connected through the inlet 12, allowing high-pressure water to be introduced from the external water source. This water then flows through the nozzle on the cylindrical nozzle 221 to rinse the inner wall of the glassware from the inside, and the bristles of the brush 222 work together to automatically clean the glassware, eliminating the need for manual cleaning. The wastewater from the cleaning process flows under gravity from the inner wall of the glassware and falls to the bottom of the water tank 11, and is discharged through the drain outlet 13. By setting multiple sets of spraying components 2 and a flexible hose structure with multiple branches, the inlet 12 can be independently connected to multiple sprayers 22 and supplied with water simultaneously, enabling the simultaneous cleaning of multiple glassware. Because the glassware is placed upside down on top of the cylindrical nozzle 221, the water sprayed from the nozzle is blocked by the side wall of the glassware and discharged from the bottom, preventing splashing onto other glassware being cleaned. This effectively avoids cross-contamination while achieving simultaneous cleaning. It effectively solves the technical problems of low cleaning efficiency and high cost caused by the shortcomings of existing laboratory glassware cleaning methods.

[0024] For example, in this embodiment of the invention, high-pressure water jets are used to rinse the glassware, and the bristles of the brush 222 are used to further clean the solution residue on the inner wall, ensuring thorough cleaning of most glassware. In addition, after each wash, the user can adjust the glassware's position relative to the cylindrical nozzle 221 by rotating it, avoiding incomplete cleaning of certain areas or sections. Overall, the cleaning is still adaptively performed by the water jets from the cylindrical nozzle 221 and the bristles of the brush 222, eliminating the need for manual wiping and effectively improving cleaning efficiency. Furthermore, after rinsing a batch of glassware, if there is no need for subsequent batches, the glassware can be held on the sprayer 22 as a support structure to dry, demonstrating excellent practicality.

[0025] Optionally, the sprayer 22 is connected to the mounting bracket 21 via the mounting cylinder 223. The top of the mounting cylinder 223 is coaxially connected to a mounting port section 224 with a smaller diameter. The mounting cylinder 223 and the mounting port section 224 are connected via a tapered tapered section 225. A spring 2231 is coaxially arranged inside the mounting cylinder 223. One end of the spring 2231 is fixedly connected to the side wall at the bottom of the mounting cylinder 223, and the other end is connected to a small ball 2232 with a diameter larger than the inner diameter of the mounting port section 224. A cylindrical nozzle 221 is telescopically installed inside the mounting port section 224. A grid hole 2211 is provided on the side wall at the bottom of the cylindrical nozzle 221. The mounting cylinder 223 is connected to the water inlet 12. For example, in this embodiment of the present invention, the sprayer 22 adopts a press-triggered structure. When not rinsing, under the elastic force of the spring 2231 inside the mounting cylinder 223, the small ball 2232 at the top of the spring 2231 abuts against the inner wall of the tapered converging section 225, thereby sealing the connection between the mounting port section 224 and the tapered converging section 225. At the same time, the cylindrical nozzle 221 is located entirely inside the mounting port section 224, and the outer side of the grid hole 2211 on its bottom sidewall is adjacent to the mounting port section 224. At this time, the water injected into the mounting cylinder 223 through the water inlet 12 is blocked by the small ball 2232 and remains inside the mounting cylinder 223, achieving self-sealing. When rinsing glassware, pressing down on the glassware from the top applies downward pressure to the cylindrical nozzle 221, causing it to move downward relative to the mounting cylinder 223. The bottom of the cylindrical nozzle 221 pushes the small ball 2232 into the mounting cylinder 223 to release the blockage at the connection between the mounting opening 224 and the tapered converging section 225. The bottom of the cylindrical nozzle 221 descends entirely into the tapered converging section 225, allowing water inside the mounting cylinder 223 to flow in through the grid holes 2211, forming a high-pressure water jet that is ejected through the nozzle on the cylindrical nozzle 221 to clean the glassware. After a period of rinsing, relaxing the pressure on the glassware causes the compressed spring 2231 to push the small ball 2232 back up to block the mounting opening 224, stopping the water flow and completing the automatic reset and sealing process. The push-to-open and shut-off spray washer 22 provided in this embodiment of the invention can achieve the formation, supply and reset of high-pressure water flow without the need for external electrical control and complex valve and pipeline settings during short-term glass rinsing. It has a simple structure, is easy to operate, and effectively reduces operating costs.

[0026] Optionally, a circular support plate 226 extends radially outward from the outer wall of the cylindrical nozzle 221. Exemplarily, in this embodiment of the invention, in conjunction with the press-to-open / close spray washer 22 structure, a flange-shaped circular support plate 226 is provided on the cylindrical nozzle 221. Its upper surface can support the inverted glassware and also serve as a force-bearing point when pressed downwards. The lower end face can serve as a limit to the pressing stroke. The maximum stroke is reached when the lower end face of the circular support plate 226 abuts against the opening end face of the mounting section 224, ensuring that the bottom of the cylindrical nozzle 221 descends entirely into the tapered converging section 225 while avoiding excessive pressing that could cause structural damage, thus improving the overall structural stability.

[0027] For example, the circular support plate 226 can also limit the inverted connection of the glassware. By customizing different cylindrical nozzles 221 according to the depth of the glassware, the distance between the circular support plate 226 and the top of the cylindrical nozzle 221 is slightly less than the depth of the glassware. This can prevent the top of the cylindrical nozzle 221 from hitting the glassware. At the same time, the nozzle of the cylindrical nozzle 221 can also be set at the top of the cylindrical nozzle 221 so that the water flow sprayed can fully contact the glassware to achieve the best cleaning effect.

[0028] Optionally, the circular support plate 226 has a plurality of water passage holes 2261 arranged in a circular array. For example, by opening a plurality of water passage holes 2261 in a circular array on the circular support plate 226, while maintaining support for the glassware, it is convenient for the liquid and water after washing to fall quickly through the circular support plate 226 into the water tank 11, avoiding sedimentation and splashing that could cause cross-contamination.

[0029] Optionally, the brush 222 is detachably mounted on the cylindrical nozzle 221 section above the circular support plate 226. Exemplarily, in this embodiment of the invention, the brush 222 can be detachably connected by having bristles arranged on the outer wall of a cylindrical sleeve, and then fitted onto the cylindrical nozzle 221, covering the section above the circular support plate 226. When not cleaning, the brush 222 can be completely removed for cleaning, or replaced entirely, ensuring subsequent cleaning effectiveness and avoiding the residue of reagents or other contaminants from repeated use.

[0030] Optionally, the mounting brackets 21 of multiple sets of spray washing components 2 are integrally connected and share the same mounting surface 211, with multiple drain holes 2111 extending through the mounting surface 211. Exemplarily, in a preferred embodiment of this utility model, an integrally formed mounting bracket 21 supports the plurality of spray washers 22, facilitating integral connection with the inner wall of the water tank 11 of the cleaning box 1, while improving support stability. Wastewater after cleaning can drain down to the bottom of the water tank 11 through the drain holes 2111 distributed on the mounting surface 211. For the installation of the spray washers 22, an array of threaded holes 2112 on the mounting surface 211 is used to achieve mating with the threaded section 2233 at the bottom of the spray washers 22. The number of spray washers 22 can be arranged according to the actual number of glassware to be cleaned, and the installation spacing of the spray washers 22 can be adaptively adjusted according to different sizes and specifications of glassware, further improving adaptability.

[0031] Optionally, a cover plate 3 is also included, which is placed over the water tank 11 and slidably connected to the side wall of the water tank 11. Exemplarily, in this embodiment of the invention, after setting up the plurality of spray washing components 2 and completing the inverted installation of the glassware, a cover plate 3, whose overall size matches the opening of the water tank 11, is placed over the water tank 11. Pressing the cover plate 3 simultaneously activates multiple press-type spray washers 22 for simultaneous cleaning, and releasing the pressure on the cover plate 3 stops the cleaning process. The cleaned glassware can be removed by holding the handle 31 located at the top of the cover plate 3 and lifting the cover plate 3 from the top opening of the water tank 11. Furthermore, by providing an elastic limiting member 4 between the cover plate 3 and the cylindrical nozzle 221, and by matching the overall contour of the elastic limiting member 4 with the inner wall of the water tank 11, it is possible to press down on the multiple sprayers 22 as a whole. By providing an elastic limiting member 4, such as a sponge pad, as a buffer between the cover plate 3 and the glassware that is inverted on the top of the sprayer 22, the wear caused by direct hard contact between the cover plate 3 and the glassware is prevented when it is pressed down, or cracking damage caused by excessive local stress is prevented, thus further improving work safety.
