Abstract
Description
Technical Field
[0001] This utility model relates to the field of instrument cleaning technology, and in particular to a laboratory instrument cleaning device. Background Technology
[0002] Laboratory instrument cleaning systems are essential equipment used in laboratories to remove contaminants, chemical residues, or microorganisms from instrument surfaces. Common types include manual scrubbing tools, ultrasonic cleaners, and automated cleaning and disinfection systems. Among these, ultrasonic cleaners, with their high efficiency and precision cleaning capabilities, have become one of the preferred devices for cleaning delicate instruments in laboratories. Ultrasonic cleaners utilize the cavitation effect of ultrasound, generating high-frequency electrical energy through a generator, which is then converted into ultrasonic mechanical vibrations. This causes dense microbubbles to form in the cleaning solution. These bubbles rapidly expand and burst under the influence of sound waves, generating powerful localized high pressure and microjets that can penetrate deep into tiny crevices, blind holes, or complex structures on the instrument surface, thoroughly removing attached dirt, grease, bloodstains, or particles.
[0003] Patent CN219253436U discloses a safe cleaning device for chemical laboratory equipment. The cleaning tank is detachably placed inside a container for the equipment. Several spray pipes are arranged inside the tank, and a liquid control mechanism is connected to these pipes to control their operation. The nozzles of the spray pipes spray cleaning solution onto the equipment in the container, and can simultaneously spray cleaning from both the left and right sides, improving the cleaning effect. The cleaning tank can be filled with cleaning solution for immersion cleaning. A tank cover prevents splashing of the cleaning solution during spray cleaning. An ultrasonic transducer subjectes the surface of the equipment to frequent and intense impacts, accelerating the dissolution of soluble contaminants and enhancing the cleaning effect of the solution.
[0004] The inventors have discovered at least the following problems in the prior art:
[0005] After the existing experimental equipment cleaning device is cleaned, the experimental equipment usually requires the staff to use a towel to wipe off most of the cleaning solution and then take another towel to wipe it carefully. Therefore, the operation is troublesome, time-consuming and labor-intensive, which limits the processing efficiency.
[0006] In addition, the holding frame can only be placed from the top. This can cause the mesh of the frame to deform due to inertia when the frame is full, thus limiting its service life.
[0007] Therefore, this solution provides a laboratory instrument cleaning device to solve the above problems. Utility Model Content
[0008] The purpose of this invention is to provide a laboratory instrument cleaning device to solve the problems of low drying efficiency of instruments after cleaning, cumbersome and time-consuming operation, and deformation of the mesh frame and reduced service life when many items are placed in the holding frame.
[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:
[0010] A laboratory instrument cleaning device includes a housing and a cleaning mechanism. The cleaning mechanism is located inside the housing. One end of the housing is connected to a side plate via a hinge. Two support mechanisms are arranged inside the housing. A placement mesh frame is arranged between the support mechanisms. Drying mechanisms are arranged on both sides of the placement mesh frame. A base is fixedly connected to the bottom of the housing. An exhaust fan and an electric hydraulic cylinder are installed on the top of the base. Side air guide blocks are arranged at both ends of the placement mesh frame and are fixedly connected to the inside of the housing.
[0011] Preferably, the support mechanism includes a top support rail and side support rails fixedly connected to both ends of the top support rail, and both the side support rails and the top support rail are fixedly connected to the outer shell.
[0012] Preferably, the cleaning mechanism includes a cleaning tank, a drain port, and a water inlet port. The four top corners of the cleaning tank are slidably connected to the side support guide rails. The drain port and the water inlet port are located at the bottom and one end of the cleaning tank, respectively. The output end of the electric hydraulic cylinder is connected to both ends of the cleaning tank.
[0013] Preferably, the four corners of the placement frame are fixedly connected to docking blocks, which are slidably connected above the top support guide rail.
[0014] Preferably, the air-drying mechanism includes an airflow box and an electric heating wire installed inside the airflow box. The airflow box has evenly distributed air inlet ports below it, and the air inlet ports are connected to the output end of the induced draft fan via flexible hoses.
[0015] Preferably, the airflow box has uniformly arrayed jet nozzles on the side near the placement frame, and the two ends of the heating wire are connected by connecting wires that pass through the airflow box and the outer shell.
[0016] Preferably, the side guide block has an arc-shaped groove on the side near the placement of the mesh frame, and a guide block is fixedly connected inside the arc-shaped groove.
[0017] The beneficial effects of this utility model are:
[0018] I. This utility model uses a drying mechanism to introduce airflow through a blower. After being heated by an electric heating wire, the airflow is evenly sprayed out from the jet nozzle to pre-dry the cleaned instruments. In addition, combined with the arc-shaped groove and guide block design of the side air guide block, the airflow is redirected to the mesh frame, which not only avoids airflow waste but also expands the drying range, reduces manual wiping time, and improves processing efficiency.
[0019] Second, the present invention features a placement frame that is slidably connected to the top support guide rail via a docking block. Depending on the number of instruments, it can be directly inserted or slid out, which is convenient to operate and can also protect the mesh of the placement frame and extend its service life.

[0033] Please refer to the following. Figures 1 to 5As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0034] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.
[0035] This utility model provides a laboratory instrument cleaning device, including a housing 1 and a cleaning mechanism 4. The cleaning mechanism 4 is located inside the housing 1. One end of the housing 1 is connected to a side plate 11 via a hinge. Two support mechanisms 6 are provided inside the housing 1. A mesh frame 3 is provided between the support mechanisms 6. A drying mechanism 7 is provided on both sides of the mesh frame 3. A base 2 is fixedly connected to the bottom of the housing 1. A blower 9 and an electric hydraulic cylinder 5 are installed on the top of the base 2. Side air guide blocks 8 are provided at both ends of the mesh frame 3. The side air guide blocks 8 are fixedly connected to the inside of the housing 1.
[0036] A PLC controller is installed on the outside of the housing 1 to control the operation of other equipment. In addition, a connection terminal is provided at the point where the connecting line 75 passes through the housing 1 for easy connection of the power supply line.
[0037] In a further embodiment, the support mechanism 6 includes a top support rail 62 and side support rails 61 fixedly connected to the lower ends of the top support rail 62. Both the side support rails 61 and the top support rail 62 are fixedly connected to the outer shell 1.
[0038] In this embodiment, the two ends of the top support rail 62 are located above the side air guide block 8, and the side air guide block 8 near the side plate 11 is connected to the outer shell 1 by plugging. That is, the left side air guide block 8 has a plugging block, so when it is necessary to pull out the mesh frame 3, the side air guide block 8 can be pulled out first.
[0039] In a further embodiment, the cleaning mechanism 4 includes a cleaning tank 41, a drain port 42, and a water inlet port 43. The four top corners of the cleaning tank 41 are slidably connected to the side support guide rail 61. The drain port 42 and the water inlet port 43 are located at the bottom and one end of the cleaning tank 41, respectively. The output end of the electric hydraulic cylinder 5 is connected to both ends of the cleaning tank 41.
[0040] In this embodiment, the cleaning mechanism 4 is an ultrasonic cleaner in the prior art. It has a generator inside, which generates high-frequency electrical energy and converts it into ultrasonic mechanical vibration, causing dense microbubbles to form in the cleaning fluid. These bubbles expand and burst rapidly under the action of sound waves, generating strong local high pressure and microjets, which can penetrate into the tiny gaps, blind holes or complex structures on the surface of experimental instruments to completely remove the attached dirt, grease, blood stains or particles. There are sliders at the four top corners of the cleaning tank 41, which can slide to the inside of the side support guide rail 61. The side support guide rail 61 is used to guide and limit the up and down sliding of the cleaning mechanism 4.
[0041] In a further embodiment, docking blocks 31 are fixedly connected to the four top corners of the mesh frame 3, and the docking blocks 31 are slidably connected above the top support guide rail 62.
[0042] In this embodiment, the top support guide rail 62 is an upward-facing notch. When there are not many instruments in the placed mesh frame 3, the docking block 31 can be directly inserted from above. When there are many instruments in the placed mesh frame 3, the placed mesh frame 3 can be removed by sliding.
[0043] In a further embodiment, the air drying mechanism 7 includes an airflow box 71 and an electric heating wire 74 installed in the airflow box 71. The airflow box 71 is provided with uniformly distributed air inlet ports 73, which are connected to the output end of the blower 9 through a flexible hose.
[0044] In this embodiment, the input end of the blower 9 is provided with a rectangular hole at the outer casing 1, so that the external airflow can be introduced into the airflow box 71 and then heated by the heating wire 74 and sprayed out from the jet nozzle 72, thereby pre-drying the instruments placed in the mesh frame 3.
[0045] In a further embodiment, the airflow box 71 has uniformly arrayed jet nozzles 72 on the side near the placement of the mesh frame 3, and the two ends of the heating wire 74 are connected to connecting wires 75, which pass through the airflow box 71 and the outer shell 1.
[0046] In this embodiment, the connecting line 75 connects to the external power supply line and the switch. When the current passes through the heating wire 74 after the power is turned on, it will generate heat and thus heat the air inside the airflow box 71.
[0047] In a further embodiment, the side guide block 8 has an arc-shaped groove 81 on the side near the placement of the mesh frame 3, and a guide block 82 is fixedly connected inside the arc-shaped groove 81.
[0048] In this embodiment, the arc groove 81 is arc-shaped, and the top cross section of the guide block 82 is similar to two Cs connected vertically, with the overlapping area in the middle aligned with the middle part of the mesh frame 3.
[0049] The working principle of this utility model is as follows:
[0050] When cleaning experimental equipment, cleaning solution and detergent can be injected into the cleaning tank 41 through a hose connected to the water inlet port 43. The equipment can then be placed orderly inside the placement frame 3. The electric hydraulic cylinder 5 is then operated via an external control device, causing the cleaning tank 41 to rise and passively immersing the placement frame 3 in the cleaning solution. The generator inside the cleaning tank 41 is then activated to generate high-frequency vibration, thereby cleaning the equipment within the placement frame 3. After cleaning, the electric hydraulic cylinder 5 can be reversed to lower the cleaning tank 41. Once the placement frame 3 is completely detached from the cleaning tank 41, the induced draft fan 9 can be activated. Power is supplied to the connecting line 75 via an electric wire. Heat is generated inside the connecting line 75. The operation of the blower 9 delivers external airflow through the hose and air inlet 73 to the airflow box 71. This airflow is heated by the heating wire 74 and blown toward the placement frame 3, thereby pre-drying the instruments inside and reducing the time for wiping the instruments later, thus improving processing efficiency. In addition, part of the airflow blown toward the placement frame 3 is blocked by the porous placement frame 3 and flows to both sides. At this time, the arc groove 81 and the guide block 82 on the inner side of the side air guide block 8 will redirect this part of the airflow back to the placement frame 3, which can avoid waste and increase the drying range.
[0051] In addition, when the equipment inside the mesh frame 3 has dried, it can be removed by opening the side plate 11 of the bracket. Guided by the docking block 31 and the top support rail 62, the mesh frame 3 can be directly pulled out, which is convenient to remove. This not only makes the operation simple, but also protects the mesh of the mesh frame and extends its service life.
[0052] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
