Technical Field

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

[0002] In geotechnical experiments, laboratory instruments often have a lot of soil stuck to them after use, so they need to be cleaned and disinfected for future use.

[0003] A search revealed a patent document with publication number CN 216225779 U, which discloses a cleaning and disinfection device for laboratory instruments. The device uses two chambers to clean and disinfect laboratory instruments, while simultaneously recycling and reusing the cleaning and disinfecting solutions.

[0004] Based on the search of the above information, it can be seen that in the prior art, although the two liquid storage chambers at the bottom are independent of each other, the cleaning liquid and disinfectant used after cleaning will spread on the upper part of the whole and cannot flow back to the corresponding storage chambers, resulting in the problem of interaction between the liquids after cleaning and disinfection. Therefore, a new cleaning and disinfection device for laboratory instruments is proposed to optimize the above-mentioned prior art. Utility Model Content

A motor 16 is fixedly installed on the top surface of the housing 1. The output end of the motor 16 is fixedly connected to the V-shaped baffle 8. The motor 16 is located at the center of the rotating disk 7.

[0022] The shell 1 is divided into three independent chambers. By rotating the position of the placement chamber 9, the first chamber 3, the second chamber 4 and the third chamber 5 corresponding to the placement chamber 9 can be adjusted. Cleaning and disinfection are in an independent and isolated state, which effectively avoids the problem of cross-contamination of cleaning and absorption solutions.

[0023] A fan 17 is fixedly installed inside the ventilation duct 11, a dust filter plate 18 is fixedly installed on the inner side of the top of the ventilation duct 11, and an electric heating grid 19 is fixedly installed on the inner side of the bottom of the ventilation duct 11.

[0024] The installation of the fan 17 and the electric heating grid 19 enables hot air drying in the third chamber 5 and above, facilitating the drying of the cleaned and disinfected experimental instruments.

[0025] The shell 1 has access ports for the first chamber 3 and above it, the second chamber 4 and above it, and the third chamber 5. Access ports are provided with access cover plates 20 on the outside of the access ports. Access cover plates 20 are fixedly installed to the shell 1 by bolts. Air outlet 6 is provided on the access cover plate 20 of the third chamber 5.

[0027] A drain valve 21 is fixedly connected to the bottom of the first chamber 3 and the second chamber 4 of the shell 1. An inlet pipe 22 is provided on the top of the first chamber 3 and the second chamber 4 of the shell 1, and a pipe cap 23 is connected to the inlet pipe 22.

[0028] The drain valve 21 allows for easy discharge of cleaning and disinfecting solutions from the first chamber 3 and the second chamber 4, while the inlet pipe 22 facilitates easy replenishment of liquids to the first chamber 3 and the second chamber 4.

[0029] A filter screen 24 is fixedly installed in the housing 1 corresponding to the first chamber 3, and the filter screen 24 covers the outside of the submersible pump 15.

[0030] The submersible pump 15 is protected from water ingress by the filter screen 24 to prevent large particles of impurities generated during cleaning of laboratory instruments from being carried and circulated.

[0031] The housing 1 is provided with a pick-up and put-out port above the third chamber 5. A door 25 is provided on the outside of the pick-up and put-out port. One side of the door 25 is hinged to the housing 1 by a hinge. The other side of the door 25 is provided with a door lock. The door lock adopts an existing lock body. The door 25 is provided with an observation window, which is transparent.

[0032] The door 25 allows for convenient placement of experimental instruments into the placement cavity 9, while also enabling the enclosure to be sealed.

[0033] Submersible pump 15, motor 16, fan 17, and electric heating grid 19 are all externally connected to power supplies and switches. Motor 16 is a servo motor, which can drive the rotating disk 7 to rotate 120° each time it works.

[0034] The working principle of this utility model is as follows: In use, open door 25 and place the laboratory instruments (non-electronic instruments, washable, such as glassware, metal containers, etc.) to be cleaned and disinfected into placement chamber 9. Then close door 25. Motor 16 drives rotating disk 7 to rotate placement chamber 9, switching it to the position corresponding to the first chamber 3. Submersible pump 15 draws cleaning solution and sprays it into placement chamber 9 through spray pipe 13, rinsing the laboratory instruments. Wastewater flows back to the first chamber 3 through perforation 10 for reuse. Motor 16 is then activated to switch rotating disk 7, moving placement chamber 9 above the third chamber 5 for drainage. Simultaneously, fan 17 is activated for drying, with air passing through dust filter 18. The wastewater is filtered, then passes through the placement chamber 9, further through the through hole 10, further through the third chamber 5, and then through the air outlet 6 to create a ventilation effect. Then, the motor 16 is activated to switch the rotating disk 7, switching the placement chamber 9 to the top of the second chamber 4. At this time, the submersible pump 15 draws the cleaning solution and sprays it into the placement chamber 9 through the spray pipe 13 to disinfect the laboratory instruments. At this time, the wastewater flows back into the second chamber 4 through the through hole 10 for reuse. The motor 16 is activated again to switch the rotating disk 7, switching the placement chamber 9 to the top of the third chamber 5 for drainage. At the same time, the fan 17 can be activated for blowing and drying, and the electric heating grid 19 can be activated for hot air drying.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
