[0032] A dust collection device is a cleaning device widely used in household, industrial, and laboratory environments. It generates negative pressure to suck in dust, debris, and other impurities, and discharges clean air through a built-in filtration system. These devices usually include a suction pump, a dust collection tube, a suction nozzle, and various filtration media, such as paper bags, cloth bags, HEPA filters, etc., to meet different cleaning needs. Whether it is to remove tiny dust, pet hair, or collect waste in industrial production, the dust collection device can provide an effective cleaning solution to keep the environment clean and hygienic.
[0033] In the related art, a dust collection device for laboratory use can not only suck in tiny dust but also suck in larger-sized items, such as experimental instruments and parts left in the corners of the laboratory. This can help experimental personnel pick up some experimental components that have fallen into dead corners and are out of reach of human hands. However, after the experimental instruments or components are sucked into the dust collection device, they will enter the dust collection box together with the tiny dust inside the dust collection device, causing contamination of the experimental instruments.
[0034] To solve the above problems, the present utility model proposes a dust collection device for laboratory use, aiming to provide a dust collection device for laboratory use that can simultaneously suck in tiny dust and lost experimental instruments and store them separately. Figures 1 to 4 It is a schematic structural diagram of an embodiment provided by the dust collection device for laboratory use of the present utility model.
[0035] Please refer to Figures 1 to 4, the present utility model proposes a dust suction device 1000 for laboratory use, which includes a housing 1, a suction pump 2 and a dust collection box 4. The housing 1 forms a cavity. The housing 1 is provided with a partition 14, and the partition 14 divides the cavity into an upper cavity 11 and a lower cavity 12. One end of the upper cavity 11 is communicated with a dust suction pipe 13. The suction pump 2 is arranged at one end of the upper cavity 11 away from the dust suction pipe 13. A grille is arranged between the suction pump 2 and the dust suction pipe 13. The grille is provided with grille holes 31. The grille divides the upper cavity 11 into a connected front cavity 111 and a rear cavity 112. The suction pump 2 is arranged in the rear cavity 112. The dust collection box 4 is arranged in the lower cavity 12 and is provided with an opening communicating with the rear cavity 112.
[0036] In the technical solution of the present utility model, a dust suction device 1000 for laboratory use is proposed, which includes a housing 1, a suction pump 2 and a dust collection box 4. A partition 14 is arranged inside the housing 1 to divide the cavity into an upper cavity 11 and a lower cavity 12. The suction pump 2 is arranged in the upper cavity 11, and a dust suction pipe 13 communicating with the outside is arranged at one end. The dust collection box 4 is arranged in the lower cavity 12. When the suction pump 2 works, negative pressure is generated in the cavity to suck in external dust and dropped experimental instruments. When the dust and the dropped experimental instruments enter the dust suction device from the dust suction pipe 13 at the same time, since a grille is arranged between the dust suction pipe 13 and the suction pump 2, and the grille divides the upper cavity 11 into a front cavity 111 and a rear cavity 112, and the grille is provided with grille holes 31, the smaller dust will enter the rear cavity 112 through the grille holes 31 on the grille, and then enter the dust collection box 4 under the influence of gravity. The larger dropped experimental instruments will be blocked by the grille, so as to separate the dust and the dropped experimental instruments and avoid the pollution of the experimental instruments by the dust.
[0037] Furthermore, in order to facilitate the dropped experimental instruments to fall after contacting the grille without blocking the grille and weakening the dust suction effect, the grille is arranged to incline downward. Specifically, please refer further to Figure 1 , when the dropped experimental instruments are sucked into the front cavity 111, they will contact the grille under the action of negative pressure. Since the grille is arranged to incline downward, the dropped experimental instruments will be subjected to the downward reaction force of the grille and their own gravity, so that the experimental instruments will fall to the bottom of the front cavity 111, and the dust will enter the rear cavity 112, realizing the separation of the two.
[0038] Furthermore, in order to reduce the influence of the dropped experimental instruments entering the front cavity 111 on the subsequent dust suction work, the partition 14 is provided with a switch door 141. Specifically, please refer further to Figure 1, the door 141 is located on the side of the grille facing the dust suction pipe 13 and can connect or cut off the front cavity 111 and the lower cavity 12. It should be noted that the door 141 can be an automatic door or a door that can be opened under the action of the heavy pressure of an object and can be reset after the object falls. The present utility model does not limit this. In an embodiment of the present utility model, the door 141 adopts a double-leaf door form. The two ends of the two door bodies are respectively hinged on the partition 14, and two torsion springs are respectively arranged. The torsion spring door 141 utilizes the principle of storing and releasing energy by the torsion spring to realize automatic opening and closing and reset. When the door is opened, the torsion spring is twisted and stores energy; when the door is released, the torsion spring attempts to return to its original state, releases energy, and pushes the door to close. If the door falls due to gravity in the open state, the torsion of the torsion spring will increase due to the gravity effect. Once released, the restoring force of the torsion spring will automatically reset the door. The advantages of this design include improving convenience, reducing manual intervention, ensuring that the door can automatically close when not fixed, thereby improving safety and energy efficiency. At the same time, since the number of door openings and closings is reduced, the service life of the door can also be extended.
[0039] For the convenience of the experimenter to take out the lost experimental instruments from the inside of the dust suction device, the dust suction device further includes a storage drawer 5. Specifically, please further refer to Figure 1 , the storage drawer 5 is arranged in the lower cavity 12 and is located below the door 141. The storage drawer 5 is used to collect the items that fall from the door 141. After the lost experimental instrument falls into the storage drawer 5 from the door 141, the experimenter can pull out the storage drawer 5 to take out the experimental instrument inside. Further, to prevent the experimental instrument from falling from a high place into the storage drawer 5 and being damaged due to gravity, a buffer plate 51 is provided at the inner bottom of the storage drawer 5. The buffer plate 51 is made of silica gel material, and when the experimental instrument falls, it can play a good buffer protection effect.
[0040] To disinfect the collected dust and garbage, the dust collection box 4 includes a spraying component 41. Specifically, please further refer to Figure 1, the spraying assembly 41 includes a water tank 411 and a spraying part 413. The water tank 411 is arranged outside the housing 1, and the spraying part 413 is arranged on the inner side wall of the lower cavity 12. The spraying part 413 is communicated with the water tank 411. The water tank 411 stores disinfectant solution, and the disinfectant solution can be sprayed into the dust collection box 4 through the spraying part 413. The disinfectant solution can effectively kill or inhibit bacteria, viruses and other harmful microorganisms that may be contained in the dust, reducing the risk of disease transmission; Secondly, spraying the disinfectant solution can reduce the resuspension of dust and avoid secondary pollution when cleaning the dust collection box 4; In addition, using the disinfectant solution can also remove or neutralize the odor in the garbage and improve the environmental hygiene; Finally, this design improves the hygiene standard of the cleaning equipment. In this way, the dust collection box 4 not only serves as a container for collecting garbage, but also becomes a primary disinfection treatment unit, improving the overall cleaning efficiency and environmental hygiene quality of the dust suction device.
[0041] Since the dust collection box 4 contains a mixture of dust solids and disinfectant solution, in order to achieve solid-liquid separation, the dust collection box 4 further includes a water filtering plate 42. Specifically, please further refer to Figure 1 , the water filtering plate 42 is detachably arranged in the lower cavity 12 and is spaced from the bottom of the lower cavity 12. The water filtering plate 42 can intercept large-particle dust impurities, and the disinfectant solution will seep into the bottom of the housing 1 along the water filtering plate 42. A sewage outlet 15 is arranged at the bottom of the housing 1 to regularly discharge the internal sewage. It is roll-mounted on the roller 9 and can be pulled out from one side of the storage drawer 5 to pour out the internal dust and garbage.
[0042] In an embodiment of the present utility model, the dust suction device further includes a filter screen 6. The filter screen 6 is arranged on the side of the suction pump 2 facing the dust suction pipe 13. The filter screen 6 adopts a HEPA filter screen. The HEPA filter screen can efficiently capture and filter out tiny particles, including dust, pollen, bacteria, viruses and other pollutants that may affect air quality and human health. The design of the HEPA filter screen ensures that at least 99.97% of the particles with a size of 0.3 microns and above are intercepted, preventing the particles from damaging the suction pump 2. In addition, the presence of the HEPA filter screen also helps to extend the service life of the dust suction device because it reduces the wear of these particles on the internal components of the machine. Therefore, the HEPA filter screen is an essential component in the dust suction device, providing important health protection for modern family and working environments.
[0043] An ultraviolet lamp 7 is also arranged above the rear cavity 112. Specifically, please further refer to Figure 1, the ultraviolet lamp 7 is arranged on the inner top surface of the housing 1 and is located in the rear cavity 112. The ultraviolet lamp 7 can emit light in the UVC band, effectively destroying the DNA or RNA structure of microorganisms such as bacteria and viruses, and realizing the disinfection and sterilization of pollutants in the cavity. Secondly, this setting helps to reduce the reproduction of microorganisms in the cavity, prevent the generation of odors, and keep the indoor air clean and fresh. In addition, using the ultraviolet lamp 7 as a disinfection means is both environmentally friendly and safe, avoiding the use of chemical disinfectants and reducing the possible harm to the environment and human body.
[0044] In an embodiment of the present utility model, the dust suction device is further provided with a moving part. The moving part includes four universal wheels 8. The universal wheels 8 enable the dust suction device to move easily in different directions without lifting the device, which is particularly important in a laboratory because the laboratory usually has limited space and dense equipment placement. In addition, the universal wheels 8 reduce the wear on the laboratory floor during the moving process, reduce noise, and enable the dust suction device to easily enter narrow or hard-to-reach areas for cleaning. This design also facilitates the operator to save physical strength and time when performing cleaning tasks, improves work efficiency, and at the same time ensures the cleanliness and safety of the laboratory environment.
[0045] The above description is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
