[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning device for a sterile laboratory. Background Technique

[0002] Cleaning devices are important equipment widely used in multiple industries, such as pharmaceutical manufacturing, semiconductor production, precision machining, food processing, and scientific research experiments. The main function of these devices is to exclude pollutants such as microparticles, harmful air, and bacteria in the air within a certain space range through specific technologies and designs, so as to provide a high-cleanliness working environment.

[0003] During the shutdown period of the currently used cleaning device, its air inlet and outlet are often in an open state, and the air in the laboratory environment can freely flow to the air ports, resulting in the easy aggregation of pollutants such as dust particles, microbial flora, and chemical residues in the air inlet and outlet areas, causing secondary pollution to the already treated clean air, seriously weakening the expected cleaning efficiency of the device, introducing external pollutants during the experiment, and leading to deviations or failures in the experimental results. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above equipment is in use, due to the inability to close the air inlet and outlet when not in use, the cleaning effect is reduced and the experimental results are affected, and thus a cleaning device for a sterile laboratory is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A cleaning device for a sterile laboratory includes a housing. A group of ventilation holes are opened on the outer surface of the housing. A group of guide rods are fixedly installed between the inner surfaces of the housing. A sealing plate one is movably sleeved between the outer surfaces of the group of guide rods. One side of the outer wall of the sealing plate one is fixedly installed with a group of spring one, and the outer surfaces of the group of spring one are fixedly connected to one side of the inner wall of the housing. The inner surface of the group of ventilation holes is movably inserted with the outer surface of the sealing plate one. Three groups of guide rails are fixedly installed between the inner surfaces of the housing. Installation plates are movably inserted between the inner surfaces of the three groups of guide rails respectively. A metal filter screen is movably inserted into the inner surface of one of the three installation plates, a fiber filter screen is movably inserted into the inner surface of another one of the three installation plates, and an activated carbon adsorption net is movably inserted into the inner surface of the remaining one of the three installation plates. A fixing plate is fixedly inserted between the inner surfaces of the housing.

[0006] Preferably, an installation hole is opened at the top of the fixing plate, and a blower is fixedly inserted into the inner surface of the installation hole.

[0007] Preferably, an air outlet is fixedly communicated with one side of the outer wall of the housing, and an air detector is arranged at the bottom of the inner wall of the air outlet.

[0008] Preferably, a set of sliding grooves are formed in the inner surface wall of the air outlet, and a set of sliders are movably embedded in the inner surface wall of the set of sliding grooves.

[0009] Preferably, a set of second springs are fixedly installed on one side of the inner wall of the set of sliding grooves, and one side of the outer wall of the set of second springs is fixedly connected to one side of the outer wall of the set of sliders. A set of connecting plates are fixedly installed on one side of the outer wall of the set of sliders.

[0010] Preferably, a second sealing plate is fixedly installed between the outer surface walls of the set of connecting plates, and one side of the outer wall of the air outlet is in contact with one side of the outer wall of the second sealing plate. An electric check valve is fixedly communicated with the bottom of the air outlet.

[0011] Preferably, the output end of the electric check valve is fixedly communicated with an air inlet pipe, and the output end of the air inlet pipe is fixedly communicated with the input end of the housing.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] In the present utility model, when the device is in use, under the action of air pressure, the first sealing plate and the second sealing plate are pushed to move and compress the first spring and the second spring, so that the air inlet and outlet are opened. After the device is closed, the compressed first spring and second spring start to stretch, driving the two sealing plates to close the air inlet and outlet, preventing pollutants such as dust, microorganisms, and chemical residues in the external environment from entering the device through the air inlet, improving the purification effect of the device, ensuring the cleanliness of the experimental environment, preventing external pollutants from entering, and reducing the erosion of impurities on the internal structure, thereby extending the overall service life of the device.

[0014] In the present utility model, the design of the replaceable filter screen enables users to quickly replace the filter screen, ensuring the continuous purification ability of the device, improving the efficiency of maintenance and replacement. The air detector can monitor the air quality in real time. Once it detects that the pollutant exceeds the standard, it triggers the electric check valve to send the air back into the housing for secondary treatment to ensure that the air quality always meets the standard.

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further describes this utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1, as Figures 1-6As shown in the figure, the utility model provides a sterile laboratory cleaning device, which includes a housing 1. A group of ventilation holes 2 are opened on the outer surface wall of the housing 1. A group of guide rods 3 are fixedly installed between the inner surface walls of the housing 1. A sealing plate 4 is movably sleeved between the outer surface walls of the group of guide rods 3. One side of the outer wall of the sealing plate 4 is fixedly installed with a group of springs 5, and the outer surface walls of the group of springs 5 are fixedly connected to one side of the inner wall of the housing 1. The inner surface walls of the group of ventilation holes 2 and the outer surface wall of the sealing plate 4 are movably inserted. Three guide rails 6 are fixedly installed between the inner surface walls of the housing 1. Installation plates 7 are movably inserted between the inner surface walls of the three guide rails 6. A metal filter screen 8 is movably inserted into the inner surface wall of one of the three installation plates 7. A fiber filter screen 9 is movably inserted into the inner surface wall of another one of the three installation plates 7. An activated carbon adsorption net 10 is movably inserted into the inner surface wall of the remaining one of the three installation plates 7. A fixing plate 11 is fixedly inserted between the inner surface walls of the housing 1. An installation hole 12 is opened at the top of the fixing plate 11. A fan 13 is fixedly inserted into the inner surface wall of the installation hole 12.

[0026] The effect achieved by the entire embodiment 1 is that after the cleaning device is started, the fan 13 will continuously draw the air at the bottom of the fixing plate 11 upward, reducing the pressure at the bottom of the housing 1. Subsequently, under the action of the pressure, the sealing plate 4 will pull the spring 5 and withdraw from the inside of the ventilation hole 2. The guide rod 3 can prevent the movement direction of the sealing plate 4 from deviating. At this time, the outside air can enter the housing 1 through the ventilation hole 2. When the device is closed, the compressed spring 5 will drive the sealing plate 4 to slide on the surface of the guide rod 3, so as to insert into the inside of the ventilation hole 2, preventing impurities in the air from entering through the ventilation hole 2, thereby maintaining the cleanliness inside the device and reducing the erosion of impurities on the internal structure, extending the service life of the device. The metal filter screen 8 can filter larger particles in the air. The fiber filter screen 9 can filter micron-sized impurities. The activated carbon adsorption net 10 can remove the odor and bacteria in the air, achieving the effect of sterilization and deodorization. The treated air will be taken to the upper part by the fan 13. When the device is used for a long time, people only need to pull out the installation plate 7 from the inside of the guide rail 6 to replace the filter screen, ensuring the purification function of the device and improving the maintenance and replacement efficiency.

[0027] Embodiment 2, as Figures 2-6As shown, one side of the outer wall of the shell 1 is fixedly connected to the air outlet 14, and the bottom of the inner wall of the air outlet 14 is provided with an air detector 15. The inner wall of the air outlet 14 is provided with a group of slide grooves 16, and the inner wall of a group of slide grooves 16 is movably embedded with a group of sliders 17. A group of springs 18 are fixedly installed on one side of the inner wall of a group of slide grooves 16, and the outer wall side of a group of springs 18 is fixedly connected to the outer wall side of a group of sliders 17. A group of connecting plates 19 are fixedly installed on one side of the outer wall of a group of sliders 17. A sealing plate 20 is fixedly installed between the outer walls of a group of connecting plates 19, and the outer wall side of the air outlet 14 is in contact with the outer wall side of the sealing plate 20. The bottom of the air outlet 14 is fixedly connected to an electric one-way valve 21, and the output end of the electric one-way valve 21 is fixedly connected to the air intake pipe 22, and the output end of the air intake pipe 22 is fixedly connected to the input end of the shell 1.

[0028] The effect achieved by the entire embodiment 2 is that after the treated air enters the air outlet 14, the air detector 15 will detect the air quality. If it is detected that there are still a lot of pollutants in the air, the electric one-way valve 21 will start, and the air will enter the air inlet pipe 22 through the electric one-way valve 21, and come to the shell 1 for secondary treatment through the air inlet pipe 22, thereby improving the purification effect of the air quality and ensuring that the cleanliness of the laboratory environment reaches a higher standard. After the air detector 15 detects that the air meets the standard, the electric one-way valve 21 will be in a closed state. At this time, the air will push the sealing plate 20, and the sealing plate 20 will drive the slider 17 to slide inside the slide groove 16 through the connecting plate 19, and squeeze the spring 2 18. The treated air will be discharged through the gap between the air outlet 14 and the sealing plate 20. The spring 2 18 can ensure that the air outlet 14 is in a closed state when not in use, preventing pollutants in the air from entering and polluting the purified air.

[0029] Working principle: After the cleaning device is started, the fan 13 continuously draws the air from the bottom of the fixed plate 11 upwards. This process causes a negative pressure area to form at the bottom of the shell 1. Under this negative pressure effect, the sealing plate 4 is subjected to downward pressure, overcomes the resistance of the spring 5, slides smoothly along the guide rod 3, and is drawn out from the air vent 2, thereby allowing the outside air to smoothly enter the shell 1 through the air vent 2. The existence of the guide rod 3 ensures the directional stability of the sealing plate 4 during movement and prevents the occurrence of deviation. When the device is closed, the spring 5 returns to its original shape, and the elastic force generated pushes the sealing plate 4 Slide along the surface of the guide rod 3 and reinsert it into the air vent 2 to form an effective barrier, effectively preventing the intrusion of impurities and pollutants in the air. This design not only maintains the cleanliness of the interior of the device, but also reduces the erosion of the internal structure by impurities, significantly extending the service life of the device. The device has a built-in multiple filtration system. The metal filter 8 serves as the primary filtration layer to effectively intercept larger particles in the air, and then the fiber filter 9 further filters out micron-sized impurities; while the activated carbon adsorption net 10 exerts its powerful adsorption capacity to remove odors and bacteria in the air, achieving the dual effects of sterilization and deodorization. After this series of treatments, the air is transported to the upper area by the fan 13. When the filtering effect decreases due to a long period of use, the user only needs to simply pull out the mounting plate 7 from the guide rail 6 to quickly replace the filter, thereby ensuring the continuous purification ability of the device and improving the efficiency of maintenance and replacement. At the air outlet end, the air detector 15 monitors the air quality passing through the air outlet 14 in real time. Once it is found that there are still many pollutants in the air, it will immediately trigger the start of the electric one-way valve 21. At this time, the unqualified air will be guided into the air inlet pipe 22 and re-enter the shell 1 for secondary treatment until the preset cleanliness level is reached. Clean standard, this process ensures that the cleanliness of the laboratory environment is always maintained at the highest level. When the air detector 15 confirms that the air quality meets the standard, the electric one-way valve 21 is automatically closed, and the treated air pushes the sealing plate 20 to move. The sealing plate 20 drives the slider 17 to slide in the slide groove 16 through the connecting plate 19 and compresses the spring 2 18, thereby forming a narrow gap between the air outlet 14 and the sealing plate 20, allowing clean air to be discharged smoothly. The design of the spring 2 18 ensures that the air outlet 14 can remain closed when not in use, effectively preventing external pollutants from contaminating the purified air.

Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
