Description

Technical Field

[0001] The utility model relates to the field of chemical instruments, in particular to a chemical instrument cleaning device. Background Art

[0002] In chemical laboratories, various chemical instruments such as test tubes, beakers, measuring cylinders, and distillation flasks are indispensable experimental tools. These instruments will inevitably be contaminated with various chemicals, dirt, and microorganisms during use, so regular cleaning and disinfection are crucial. However, when cleaning test tubes, traditional ultrasonic cleaners need to place the test tube rack into the ultrasonic cleaning device together. However, when cleaning test tubes of multiple diameters, the ultrasonic cleaning device has limited capacity and cannot simultaneously place test tubes of multiple diameters into the ultrasonic cleaning device for cleaning, reducing the efficiency of the device in cleaning chemical instruments. Utility Model Content

[0003] In order to overcome the disadvantage of the above-mentioned prior art that the test tube rack needs to be frequently replaced to clean the test tubes due to volume limitations, the technical problem is to provide a chemical instrument cleaning device that can simultaneously clean test tubes of different diameters.

[0004] The technical solution is as follows: A chemical instrument cleaning device includes an ultrasonic cleaning machine, a hanger, a support seat, a spring, a cleaning plate and a test tube rack. The hangers are movably placed on the front and back sides of the ultrasonic cleaning machine. The bottom of the hanger is rotatably connected to the support seat. A spring is sleeved on the bottom of the hanger. One end of the spring is fixedly connected to the support seat, and the other end of the spring is fixedly connected to the hanger. The bottom of the support seat is fixedly connected to the cleaning plate. A fixing hole is opened on the cleaning plate, and the inner bore of the fixing hole is threaded. A drainage hole is opened on the cleaning plate, and a test tube rack for placing test tubes of different diameters is threaded on the fixing hole.

[0005] Preferably, it also includes a fixed seat, a limit block and a torsion spring. The tops of the front and rear sides of the ultrasonic cleaning machine are fixedly connected to the fixed seat. The limit block for fixing the bracket is rotatably connected to the fixed seat. The limit block is sleeved with a torsion spring. One end of the torsion spring is fixedly connected to the fixed seat, and the other end of the torsion spring is fixedly connected to the limit block.

[0006] Preferably, a cleaning liquid storage tank and a pressure pump are further included. The top right side of the ultrasonic cleaning machine is fixedly connected to the cleaning liquid storage tank, and the top of the cleaning liquid storage tank is rotatably connected to the pressure pump for adding cleaning liquid.

[0007] Preferably, a blocking seat and a blocking net are also included. The tops of the left and right sides of the ultrasonic cleaning machine are fixedly connected with the blocking seats, and the blocking net is clamped on the blocking seat to prevent liquid splashing inside the ultrasonic cleaning machine.

[0008] Preferably, a liquid level observation window is further included, and the front portion of the cleaning liquid storage tank is fixedly connected to the liquid level observation window.

[0009] Preferably, a vibration block is included for assisting the draining of the cleaning plate, and the vibration blocks are fixedly connected to the inner walls on both sides of the ultrasonic cleaning machine.

[0010] The beneficial effects are: 1. By screwing test tube racks of different heights and sizes into the fixed holes of the cleaning plate, and placing the test tube mouths downward on the test tube rack, and then placing the cleaning plate in the cleaning area of the ultrasonic cleaning machine through the hanger, it is possible to clean test tubes of different shapes and sizes without using a test tube rack, thereby achieving the effect of improving cleaning efficiency.

[0011] 2. The torsion spring can be compressed by rotating the limit block counterclockwise. After the hanger is properly placed, the limit block is released. The torsion spring will automatically drive the limit block to rotate clockwise and firmly lock the hanger, ensuring that the hanger will not move or fall off in a complex environment with high-speed vibration and liquid flow, thereby avoiding safety hazards such as test tube damage and splashing of cleaning liquid caused by the movement of the hanger, and greatly improving the stability and safety of the equipment operation.

[0012] 3. The cleaning plate contacts the vibration block during its rising process in the ultrasonic cleaning machine. The extrusion of the vibration block and the reset action of the spring realize the automatic drainage function of the cleaning plate. This process not only improves the dryness of the cleaning plate surface, but also promotes the better flow of the cleaning liquid along the drain trough, reducing the risk of residue and secondary contamination.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] Example: A chemical instrument cleaning device, such as Figure 1-4 As shown, it includes an ultrasonic cleaning machine 1, a hanger 2, a support seat 3, a spring 4, a cleaning plate 5 and a test tube rack 8. The hanger 2 is movably placed on the front and back sides of the ultrasonic cleaning machine 1. The bottom of the hanger 2 is rotatably connected to the support seat 3. The bottom of the hanger 2 is sleeved with a spring 4. One end of the spring 4 is fixedly connected to the support seat 3, and the other end of the spring 4 is fixedly connected to the hanger 2. A cleaning plate 5 is welded to the bottom of the support seat 3. A fixing hole 6 is opened on the cleaning plate 5. The inner bore of the fixing hole 6 is threaded. A drain hole is opened on the cleaning plate 5. The fixing hole 6 is threaded and useful. A test tube rack 8 is provided for placing test tubes of different diameters. In order to adapt to different test tubes and allow the test tubes to be better fixed by the test tube rack 8, there are several test tube racks 8 of different heights on the cleaning plate 5, and also includes a cleaning liquid storage tank 12 and a pressing pump 13. The cleaning liquid storage tank 12 is fixedly connected to the top right side of the ultrasonic cleaning machine 1. The top of the cleaning liquid storage tank 12 is rotatably connected to the pressing pump 13 for adding cleaning liquid. It also includes a liquid level observation window 16. The front of the cleaning liquid storage tank 12 is fixedly connected to the liquid level observation window 16 through waterproof gel.

[0021] Before using the ultrasonic cleaning machine 1, the user first holds the hanger 2 to take the cleaning plate 5 out of the ultrasonic cleaning machine 1, adds clean water to the ultrasonic cleaning machine 1, and rotates the water outlet of the pressing pump 13 to the left, presses the pressing pump 13, and the pressing pump 13 will press the cleaning liquid out of the cleaning liquid storage tank 12 and add it to the cleaning pool of the ultrasonic cleaning machine 1, thereby improving the convenience of using the device. After the cleaning liquid is filled, the user can observe the remaining cleaning liquid in the cleaning liquid storage tank 12 through the liquid level observation window 16, which is convenient for the operator to observe. After the cleaning liquid is added, the user can screw the test tube racks 8 of different heights into the fixing holes 6 through the bottom threads according to the number and shape of the test tubes to be cleaned, and then place the test tubes with their mouths facing downward on the test tube rack 8. After confirming that the test tubes are placed firmly to avoid falling during the cleaning process, the cleaning plate 5 is placed in the cleaning area of the ultrasonic cleaning machine 1 through the hanger 2, and the cleaning liquid is allowed to cover the test tubes on the cleaning plate 5. This makes it possible to clean test tubes of different shapes and sizes without using the test tube rack 8, thereby improving the cleaning efficiency.

[0022] like Figure 1-3 As shown, it also includes a fixed seat 9, a limit block 10 and a torsion spring 11. The tops of the front and rear sides of the ultrasonic cleaning machine 1 are fixedly connected to the fixed seat 9. The limit block 10 for fixing the hanger 2 is rotatably connected to the fixed seat 9. The torsion spring 11 is sleeved on the limit block 10. One end of the torsion spring 11 is fixedly connected to the fixed seat 9, and the other end of the torsion spring 11 is fixedly connected to the limit block 10.

[0023] In order to prevent the hanger 2 from moving during the operation of the ultrasonic cleaning machine 1, before placing the hanger 2 on the ultrasonic cleaning machine 1, the user needs to rotate the limit block 10 counterclockwise. At this time, the limit block 10 will squeeze the torsion spring 11, so that the torsion spring 11 is in a compressed state. After the operator places the hanger 2, the limit block 10 is released. At this time, the torsion spring 11 will cause the limit block 10 to move clockwise to complete the limitation of the hanger 2. When no external force is applied, the torsion spring 11 will cause the limit block 10 to maintain a clockwise rotation trend to fix the hanger 2, thereby achieving the effect of preventing the hanger 2 from moving during the operation of the ultrasonic cleaning machine 1.

[0024] like Figure 1 As shown, it also includes a blocking seat 14 and a blocking net 15. The tops of the left and right sides of the ultrasonic cleaning machine 1 are fixedly connected with the blocking seat 14 by bolts. The blocking seat 14 is made of elastic alloy. The blocking net 15 is clamped on the blocking seat 14 to prevent liquid splashes inside the ultrasonic cleaning machine 1.

[0025] The last step in starting the ultrasonic cleaning machine 1 is to insert the blocking net 15 into the blocking seat 14. The blocking net 15 prevents the cleaning liquid from splashing during the use of the ultrasonic cleaning machine 1, thereby protecting the user. When the cleaning is completed, the blocking net 15 needs to be removed from the blocking seat 14 first.

[0026] like Figure 1 and 2 As shown, a vibration block 17 is also included for assisting the cleaning plate 5 in draining water. The vibration blocks 17 are fixedly connected to the inner walls on both sides of the ultrasonic cleaning machine 1.

[0027] When the cleaning plate 5 needs to be taken out, the cleaning plate 5 rises in the ultrasonic cleaning machine 1. At this time, the cleaning plate 5 will contact the vibration block 17 and be squeezed by the vibration block 17. At this time, the cleaning plate 5 will move to the other side where the vibration block 17 is installed. At this time, the spring 4 is compressed. When the cleaning plate 5 moves upward to a height higher than the vibration block 17, the spring 4 relaxes, causing the cleaning plate 5 to reset, thereby allowing the cleaning liquid to flow out better along the drain trough 7, thereby achieving the effect of assisting the cleaning plate 5 to drain.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
