Description

Technical Field

[0001] The utility model relates to the technical field of experimental sample cleaning, in particular to a self-cleaning noise reduction type ultrasonic cleaning instrument. Background Art

[0002] Ultrasonic cleaning technology is based on the "cavitation effect" produced when ultrasonic waves propagate in liquids. When ultrasonic waves pass through the cleaning liquid, tens of thousands of tiny bubbles are formed in the liquid. These bubbles grow rapidly under the action of sound pressure and collapse instantly during the negative pressure cycle, releasing powerful energy, forming a local high-pressure and high-temperature environment, thereby stripping away pollutants on the surface of the instrument and in tiny gaps, achieving the purpose of efficient cleaning. This process is particularly effective for cleaning laboratory test samples with complex structures, and can penetrate into every detail of the sample to achieve comprehensive, no-dead-angle cleaning. During the cleaning process, a large number of suspended particles and decomposed stains will be generated. If these impurities are not handled in time, they will be re-deposited on the cleaning object, causing secondary contamination.

[0003] The invention application with publication number CN110860521A discloses a closed noise-reducing ultrasonic cleaning machine, comprising: a shell, a silo, an ultrasonic generator, an energy-absorbing mechanism and a machine hatch. The shell is provided with a silo inside, an ultrasonic generator is provided outside the silo, an energy-absorbing mechanism is provided outside the ultrasonic generator, the energy-absorbing mechanism is fixed on the shell, and a machine hatch is provided on the top of the shell.

[0004] As in the above technical solution, the silo is enclosed in the shell. Therefore, during the ultrasonic cleaning process, the suspended particles and decomposed stains generated need to wait until the door is opened after the cleaning is completed to be cleaned. This structure will cause the pollutants to stay in the water for too long, making the water cleanliness poor. When the experimental samples are cleaned in this water, there is a risk of secondary contamination. Utility Model Content

DETAILED DESCRIPTION

[0049] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] like Figure 1-6 As shown, a self-cleaning noise-reducing ultrasonic cleaning instrument of the utility model comprises an ultrasonic cleaning tank 1 , a water filter 2 and a latch 3 .

[0051] The ultrasonic cleaning tank 1 is a rectangular square tank with an open top, and a first countersunk hole 101 is arranged horizontally on the upper side of the tank wall. Figure 5 As shown, a second countersunk hole 102 is vertically arranged at the top of the ultrasonic cleaning tank 1, and the second countersunk hole 102 penetrates the first countersunk hole 101 downwardly, and the axis lines of the second countersunk hole 102 and the first countersunk hole 101 are cross-staggered, and the second countersunk hole 102 and the first countersunk hole 101 are connected to each other;

[0052] The water filter 2 is vertically arranged on the inner side of the ultrasonic cleaning tank 1, and is used to suck the water in the ultrasonic cleaning tank 1 and filter it, and then re-inject the filtered water into the ultrasonic cleaning tank 1, so as to facilitate the real-time cleaning of the water in the tank, effectively remove pollutants in the water, make the water clean, and reduce the risk of secondary contamination of the experimental samples by the water. At the same time, through filtering, the water in the ultrasonic cleaning tank 1 does not need to be frequently replaced, which saves water and reduces labor.

[0053] Specifically, the water filter 2 is detachably installed on the inner side of the ultrasonic cleaning tank 1, such as Figure 2-3 As shown, a columnar protrusion 201 is fixedly provided on the side of the water filter 2, and a pin hole 202 is vertically provided on the protrusion 201. Figure 4 As shown, the protrusion 201 is inserted into the first countersunk hole 101, and the pin 3 is vertically inserted into the second countersunk hole 102 and passes through the pin hole 202. Through this plug-in structure, the water filter 2 is fixed to the inner side of the ultrasonic cleaning tank 1 and can be disassembled, which is convenient for the later maintenance of the water filter 2.

[0054] In the above-mentioned plug-in structure, the end of the protrusion 201 away from the submersible pump 21 is configured in a truncated cone shape, so as to facilitate the insertion of the protrusion 201 into the first countersunk hole 101 .

[0055] At the same time, the latch pin 3 adopts a semi-axle bolt structure, which is convenient for installation and disassembly. Specifically, the latch pin 3 includes a threaded rod 31 and a smooth rod 32, wherein the threaded rod 31 and the smooth rod 32 are coaxially arranged and fixedly connected, and the diameter of the threaded rod 31 is larger than the diameter of the smooth rod 32; a shackle groove 301 is provided at one end of the threaded rod 31 away from the smooth rod 32; the smooth rod 32 passes through the pin hole 202 and is slidably connected; the second countersunk hole 102 is a threaded hole, and its thread is threadedly connected with the threaded rod 31; when the protrusion 201 is inserted into the first countersunk hole 101, the latch pin 3 is inserted into the second countersunk hole 102, and then the latch pin 3 is screwed so that the threaded rod 31 of the latch pin 3 is screwed into the second countersunk hole 102, and the screwing is continued to make the smooth rod 32 pass through the pin hole 202 to achieve plug-in fixation.

[0056] In the above structure, the water filter 2 includes a submersible pump 21 and a filter cartridge 22, wherein a water suction port 203 is provided at the bottom of the submersible pump 21, and a water outlet 204 is provided at the side; one end of the filter cartridge 22 is fixedly provided on the water suction port 203, and the other end extends toward the bottom of the ultrasonic cleaning tank 1; the protrusion 201 is provided on the side of the submersible pump 21; the interior of the filter cartridge 22 is filled with coarse filter cotton, activated carbon, fine filter cotton and sieve plate in sequence from bottom to top. When absorbing water, the submersible pump 21 is energized to absorb water, and the lower end of the filter cartridge 22 generates suction to suck the water in the tank. The sucked water passes through the coarse filter cotton, activated carbon, fine filter cotton and sieve plate in sequence and then flows out from the water outlet 204. In the process, multi-layer filtration is achieved through the coarse filter cotton, activated carbon, fine filter cotton and sieve plate, so that the water discharged from the water outlet 204 is relatively clean.

[0057] In order to improve the water absorption effect, the mouth of the lower end of the filter cartridge 22 is set in a funnel shape. This shape enables the lower end of the filter cartridge 22 to have greater suction force, thereby improving the water absorption effect.

[0058] In addition, if Figure 7 As shown, a self-cleaning noise-reducing ultrasonic cleaning instrument of the utility model further includes a soundproof box 4, a box cover 5, a sewage pipe 8 and an ultrasonic converter 9.

[0060] The box cover 5 is arranged at the entrance and exit 501 and is hinged on the soundproof box 4 to form a side-opening door structure; the ultrasonic cleaning tank 1 is arranged inside the soundproof box 4 along the transverse sliding direction, and the ultrasonic cleaning tank 1 selectively passes through the entrance and exit 501; when the ultrasonic cleaning tank 1 needs to be moved out, the entrance and exit 501 is opened, and then the ultrasonic cleaning tank 1 is pulled out of the soundproof box 4 in the horizontal direction. At this time, the experimental samples can be taken and placed in the ultrasonic cleaning tank 1, and the ultrasonic cleaning tank 1 can also be maintained, which is more convenient. During subsequent cleaning, the ultrasonic cleaning tank 1 is pushed into the soundproof box 4, and then the box cover 5 is closed.

[0061] In order to facilitate observation of the interior of the soundproof box 4 and to facilitate opening the box, a glass window and a door handle are provided on the box cover 5.

[0062] In the above structure, the ultrasonic cleaning tank 1 and the sound insulation box 4 are slidably matched through the slide plate 6. Specifically, the slide plate 6 is fixedly set at the bottom of the ultrasonic cleaning tank 1; a slide groove 7 is set on each side of the slide plate 6, and the slide groove 7 is fixedly set on the inner wall of the sound insulation box 4; the side end of the slide plate 6 is set on the inner side of the slide groove 7 along the transverse sliding.

[0063] The sewage pipe 8 and the ultrasonic converter 9 are fixedly arranged at the bottom of the ultrasonic cleaning tank 1; the sewage pipe 8 is used to drain the water in the ultrasonic cleaning tank 1, and a valve is arranged in the middle section of the sewage pipe 8 to control the on-off of the sewage pipe 8; the ultrasonic converter 9 is used to emit ultrasonic waves into the ultrasonic cleaning tank 1.

[0064] The method of using the self-cleaning noise reduction ultrasonic cleaning instrument of the utility model is as follows:

[0065] First, install the water filter 2 into the ultrasonic cleaning tank 1. During installation, first insert the protrusion 201 into the first countersunk hole 101, then insert the pin 3 into the second countersunk hole 102, and fix it through the pin hole 202 to complete the installation and fixation of the water filter 2.

[0066] During cleaning, the submersible pump 21 is powered on to absorb water, and the lower end of the filter cartridge 22 generates suction to suck the water in the tank. The sucked water passes through the coarse filter cotton, activated carbon, fine filter cotton and sieve plate in sequence and then flows out from the water outlet 204. During the process, multi-layer filtration is achieved through the coarse filter cotton, activated carbon, fine filter cotton and sieve plate. The filtered water is discharged from the water outlet 204 back into the ultrasonic cleaning tank 1 to achieve water filtration.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
