Description

Technical Field

[0001] This utility model belongs to the field of instrument and equipment cleaning technology, and specifically relates to a cleaning device for laboratory instruments and equipment. Background Technology

[0002] Laboratory instruments are indispensable tools in scientific research and experimental analysis. They provide accurate and reproducible data to help scientists observe and test. Cleaning devices for laboratory instruments are key components in ensuring a clean experimental environment and stable instrument performance. These devices are diverse and feature-rich, designed to meet the cleaning needs of different types of instruments. When selecting and using cleaning devices, it is necessary to comprehensively consider the type of instrument, cleaning requirements, and the actual conditions of the laboratory. Understanding the performance parameters of cleaning devices, such as cleaning efficiency, cleaning effect, and degree of damage to instruments, is crucial to ensuring the selection of appropriate cleaning devices.

[0003] Announcement No. "CN221133405U" discloses a cleaning device for laboratory instruments and equipment, including an ultrasonic cleaning box. Support feet are fixedly installed on the lower surface of the ultrasonic cleaning box near its four corners. A control panel is provided on the front surface of the ultrasonic cleaning box. Handles are fixedly installed on both side surfaces of the ultrasonic cleaning box near its upper end. Adjustable components are movably embedded on both side surfaces of the ultrasonic cleaning box, located on one side of the handles. After cleaning, pulling the adjustable component causes its positioning rod to be pulled out of the positioning groove. Rotating the adjustable component then causes a flap to rotate, lifting a tray upwards. When the tray reaches its highest point, it detaches from the cleaning solution in the ultrasonic cleaning box. This eliminates the need to remove the items from the ultrasonic cleaning box and drain them after cleaning.

[0004] Although the aforementioned utility model features a rotating adjusting component that drives a flip plate to rotate, lifting the tray upwards and removing it from the cleaning solution in the ultrasonic cleaning chamber once it reaches its highest point, eliminating the need to remove and drain items after cleaning, it generates high-frequency vibrations during operation. These vibrations produce significant noise, and prolonged exposure to such noise can potentially lead to hearing damage. Furthermore, the vibrations create additional stress on the equipment and its connected components, increasing the risk of damage. This damage may manifest as loosening, detachment, or breakage of components, ultimately affecting the normal operation and lifespan of the equipment. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cleaning device for laboratory instruments and equipment, which solves the problem of high-frequency vibrations generated during operation. These vibrations produce significant noise and cause additional stress to the equipment itself and its connected components, thereby increasing the risk of equipment damage. Such damage may manifest as loosening, detachment, or breakage of components, thus affecting the normal operation and service life of the equipment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A cleaning device for laboratory instruments and equipment includes an ultrasonic cleaning chamber. A control panel is installed at one end of the ultrasonic cleaning chamber. Handles are symmetrically fixedly connected to both ends of the ultrasonic cleaning chamber. A cleaning tank is opened at the upper end of the ultrasonic cleaning chamber. A fixed base is symmetrically fixedly connected to the bottom end of the cleaning tank. A lifting component is installed inside the fixed base. An installation base is slidably connected to the outside of the fixed base. A cleaning basket is threadedly connected to one end of the installation base. A base is installed at the bottom end of the ultrasonic cleaning chamber. Shock-absorbing components are symmetrically installed at the bottom end of the base and near the chamfer between the bottom end of the ultrasonic cleaning chamber and the bottom end of the base.

[0008] The vibration damping assembly includes a vibration damping seat, a first limiting post, an internal hole, a first damping spring, and a second limiting post. Vibration damping seats are symmetrically fixedly connected to the bottom of the base and near the chamfer at the bottom of the ultrasonic cleaning chamber. A first limiting post is fixedly connected to the upper end of the vibration damping seat inside the base. An internal hole is formed at the upper end of the first limiting post, and a first damping spring is fixedly connected to the bottom end of the internal hole. A second limiting post is fixedly connected to the other end of the first damping spring, and the second limiting post is slidably connected to the internal hole. The end of the second limiting post furthest from the first damping spring is fixedly connected to the bottom end of the vibration damping seat at the bottom of the ultrasonic cleaning chamber. A second damping spring is sleeved on the outer side of both the first and second limiting posts. The two ends of the second damping spring are fixedly connected to the opposite ends of the vibration damping seat. This design reduces the impact of vibration on the equipment, thereby improving the accuracy and stability of cleaning. It also reduces the impact of vibration on the equipment structure, extending the equipment's service life. Furthermore, it reduces vibration transmission, thus reducing noise generation and propagation to a certain extent, providing a quieter and more comfortable working environment for the laboratory.

[0009] As a preferred technical solution, the lifting assembly includes a drive motor, a lead screw, a guide rod, a moving block, and a sliding block. A cavity is formed inside the fixed base. The drive motor is mounted on the upper end of the fixed base. The output end of the drive motor extends into the cavity and is fixedly connected to the lead screw. The other end of the lead screw is rotatably connected to one end inside the cavity. A guide rod is fixedly connected inside the cavity. Moving blocks are fitted onto both the guide rod and the lead screw. A sliding block is fixedly connected to one end of the moving block, and the other end of the sliding block extends out of the side of the fixed base and is fixedly connected to one end of the mounting base. The lead screw and the moving block are threaded together, while the guide rod and the moving block are slidably connected. Sliding grooves are formed on opposite ends of the fixed base, communicating with the cavity. The sliding grooves and the sliding blocks are slidably connected. This design can quickly remove residual cleaning fluid from the instrument surface, preventing secondary contamination or corrosion that may result from prolonged contact with the cleaning fluid. This improves cleaning efficiency, ensures the instrument is ready for use quickly after cleaning, and helps reduce potential damage from the cleaning fluid, thereby extending the instrument's lifespan.

[0010] As a preferred technical solution, guide grooves are symmetrically opened at both ends of the cleaning tank, and guide blocks are symmetrically fixedly connected to both ends of the cleaning basket. The guide blocks are slidably connected to the guide grooves. The sliding of the guide blocks in the guide grooves can ensure the stability of the cleaning basket during the lifting process, and can prevent the cleaning basket from deviating or shaking during the lifting process, thereby ensuring that the cleaning basket can accurately reach the predetermined position.

[0011] As a preferred technical solution, a drain pipe is fixedly connected to the outer wall of the ultrasonic cleaning chamber, and a valve is installed on the outer wall of the drain pipe, which facilitates the discharge of the cleaning fluid inside the ultrasonic cleaning chamber and improves the work efficiency of the experimental personnel.

[0012] In summary, the present invention has the following main advantages:

[0013] First, in this utility model, when the ultrasonic cleaning chamber is operating, the vibration generated causes the ultrasonic cleaning chamber to drive the second limiting post to descend. The second limiting post slides inside the built-in hole of the first limiting post and presses against the first damping spring, which is then compressed. At the same time, the buffer seat at the bottom of the ultrasonic cleaning chamber presses against the buffer seat on the base, and the second damping spring is compressed. This absorbs and disperses the vibration generated when the ultrasonic cleaning chamber is operating, reducing the impact of vibration on the equipment, thereby improving the cleaning accuracy and stability. It also reduces the impact of vibration on the equipment structure, extends the service life of the equipment, and reduces vibration transmission, thereby reducing the generation and propagation of noise to a certain extent, providing a quieter and more comfortable working environment for the laboratory.

[0014] Secondly, in this invention, laboratory instruments are placed inside the cleaning basket, the drive motor is started, and the lead screw is rotated. The lead screw rotates with the moving block, thereby controlling the moving block to lift and lower the sliding block. The sliding block lifts and lowers the mounting base and the cleaning basket. At the same time, the moving block on the other side slides outside the guide rod, controlling the laboratory instruments to descend into the cleaning solution for cleaning. After cleaning, the instruments are lifted to drain. This method can quickly remove residual cleaning solution from the instrument surface, avoiding secondary pollution or corrosion that may occur if the cleaning solution stays on the instrument for too long. It helps to improve cleaning efficiency, ensures that the instruments can quickly reach a usable state after cleaning, and helps to reduce the potential damage of the cleaning solution to the instruments, thereby extending the service life of the instruments.

[0021] refer to Figures 1 to 4The cleaning device for laboratory instruments and equipment described in this embodiment includes an ultrasonic cleaning box 1. A control panel 14 is installed at one end of the ultrasonic cleaning box 1. Handles 8 are symmetrically fixedly connected to both ends of the ultrasonic cleaning box 1.

[0022] The shock absorption assembly 12 includes a shock absorption seat 121, a first limiting post 122, an internal hole 123, a first shock absorption spring 124, and a second limiting post 125. The shock absorption seat 121 is symmetrically fixedly connected to the bottom of the base 9 and near the chamfer of the bottom of the ultrasonic cleaning chamber 1. The first limiting post 122 is fixedly connected to the upper end of the shock absorption seat 121 inside the base 9. An internal hole 123 is formed at the upper end of the first limiting post 122. The bottom end of the internal hole 123 is fixedly connected to the first shock absorption spring 124. The other end of the first shock absorption spring 124 is fixedly connected to the second limiting post 125. The second limiting post 125 is slidably connected to the internal hole 123. The end of the second limiting post 125 away from the first shock absorption spring 124 is connected to the bottom of the ultrasonic cleaning chamber 1. The bottom end of the shock-absorbing seat 121 is fixedly connected. The first limiting post 122 and the second limiting post 125 are fitted with a second shock-absorbing spring 13. The two ends of the second shock-absorbing spring 13 are fixedly connected to the opposite ends of the shock-absorbing seat 121. When the ultrasonic cleaning box 1 is operating, the vibration generated causes the ultrasonic cleaning box 1 to drive the second limiting post 125 down. The second limiting post 125 slides inside the built-in hole 123 of the first limiting post 122. The second limiting post 125 presses against the first shock-absorbing spring 124, and the first shock-absorbing spring 124 is compressed. At the same time, the buffer seat at the bottom of the ultrasonic cleaning box 1 presses against the buffer seat on the base 9, and the second shock-absorbing spring 13 is compressed, so as to absorb and disperse the vibration generated when the ultrasonic cleaning box 1 is operating.

[0023] refer to Figure 3The lifting assembly 16 includes a drive motor 161, a lead screw 162, a guide rod 163, a moving block 164, and a sliding block 165. A cavity 17 is formed inside the fixed base 3. The drive motor 161 is mounted on the upper end of the fixed base 3. The output end of the drive motor 161 extends into the cavity 17 and is fixedly connected to the lead screw 162. The other end of the lead screw 162 is rotatably connected to one end inside the cavity 17. The guide rod 163 is fixedly connected inside the cavity 17. Moving blocks 164 are fitted onto both the guide rod 163 and the lead screw 162. A sliding block 165 is fixedly connected to one end of the moving block 164. The other end of the sliding block 165 extends out of the side of the fixed base 3 and is fixedly connected to one end of the mounting base 4. The lead screw 162 and the moving block 164 are threaded together. The guide rod 163 and the moving block 164 are slidably connected. The fixed base 3 has sliding grooves 18 on opposite ends. The sliding grooves 18 are connected to the inside of the cavity 17. The sliding grooves 18 and the sliding block 165 are slidably connected. The laboratory instruments and equipment are placed inside the cleaning basket 5. The drive motor 161 is started to control the lead screw 162 to rotate. The lead screw 162 and the moving block 164 rotate in a threaded manner, thereby controlling the moving block 164 to drive the sliding block 165 to rise and fall. The sliding block 165 drives the mounting base 4 and the cleaning basket 5 to rise and fall. At the same time, the moving block 164 on the other side slides outside the guide rod 163 to control the laboratory instruments to descend into the cleaning solution for cleaning. After cleaning, the laboratory instruments are controlled to rise and drain.

[0024] refer to Figures 1 to 2 The cleaning tank 2 has guide grooves 7 symmetrically opened at both ends. The cleaning basket 5 has guide blocks 6 symmetrically fixedly connected at both ends. The guide blocks 6 and the guide grooves 7 are slidably connected. When the cleaning basket 5 is raised or lowered, the cleaning basket 5 drives the guide blocks 6 to slide inside the guide grooves 7.

[0025] refer to Figure 1 A drain pipe 10 is fixedly connected to the outer wall of the ultrasonic cleaning chamber 1. A valve 11 is installed on the outer wall of the drain pipe 10. When the valve 11 is activated, the cleaning fluid inside the ultrasonic cleaning chamber 1 can be discharged through the drain pipe 10.

[0026] Operating principle and advantages: First, place the laboratory instruments and equipment inside the cleaning basket 5, start the drive motor 161, and control the lead screw 162 to rotate. The lead screw 162 rotates with the moving block 164, thereby controlling the moving block 164 to drive the sliding block 165 to rise and fall. The sliding block 165 drives the mounting base 4 and the cleaning basket 5 to rise and fall. At the same time, the moving block 164 on the other side slides outside the guide rod 163, controlling the laboratory instruments to descend into the cleaning solution for cleaning. When the ultrasonic cleaning box 1 is operating, the vibration generated causes the ultrasonic cleaning box 1 to drive the second limiting post 125 to descend. The second limiting post 125 slides inside the built-in hole 123 of the first limiting post 122. The second limiting post 125 presses against the first shock-absorbing spring 124, and the first shock-absorbing spring 124 is compressed. At the same time, the buffer seat at the bottom of the ultrasonic cleaning box 1 presses against the buffer seat on the base 9, and the second shock-absorbing spring 13 is compressed, absorbing and dispersing the vibration generated when the ultrasonic cleaning box 1 is operating. After cleaning, the experimental instruments are controlled to rise and drain.

[0027] This invention can reduce the impact of vibration on equipment, thereby improving the accuracy and stability of cleaning. It can also reduce the impact of vibration on the equipment structure, extend the service life of the equipment, and reduce vibration transmission, thereby reducing the generation and propagation of noise to a certain extent, providing a quieter and more comfortable working environment for the laboratory.
