Description
Technical Field
[0001] This application relates to the field of fume hood technology, and more specifically, to a fume hood that is easy to maintain. Background Technology
[0002] Fume hoods are core local exhaust and safety protection equipment in laboratories. Their main function is to capture, isolate and remove harmful gases (such as volatile chemical reagent vapors and toxic fumes), dust, odors or moisture generated during experiments, protecting laboratory personnel from these harmful substances at the source, while maintaining the safety and cleanliness of the local laboratory environment.
[0003] Simply put, it's like a "safety shield" in the laboratory—through a specific structural design and ventilation system, it "locks" potentially harmful pollutants inside the cabinet and discharges them directly to the outside (or recirculates them after purification), preventing them from spreading into the air inside the laboratory.
[0004] In practice, it has been found that when using existing equipment, after the experiment is completed, it needs to be left to stand for a period of time to allow the gas to dissipate. After that, the inside needs to be cleaned. The current cleaning method is manual cleaning, which involves spraying cleaning agent on the inner surface and then wiping it. This operation is cumbersome and time-consuming. In addition, it is difficult for people to wipe the entire surface during manual cleaning, resulting in some areas not being disinfected and cleaned. In view of this, we propose a fume hood that is easy to maintain. Summary of the Invention

Detailed Implementation
[0014] The present application will be further described in detail below with reference to the accompanying drawings.
[0015] Reference Figure 1 - Figure 6 This application discloses a fume hood that is easy to maintain, including a fume hood body 1, a maintenance cabinet assembly 2, a cleaning assembly A3, and a cleaning assembly B4. A storage cabinet 11 is fixedly installed at the bottom of the fume hood body 1, an operation panel 12 is installed on the outside of the fume hood body 1, a negative pressure pipe 13 is installed on the top of the fume hood body 1, and a tempered explosion-proof glass door 14 is installed on the inside of the fume hood body 1. The maintenance cabinet assembly 2 is installed on the outside of the fume hood body 1 for quick opening for maintenance. The cleaning assembly A3 is slidably installed on the inside of the fume hood body 1 for cleaning the inner surface of the fume hood body 1. The cleaning assembly B4 is fixedly installed on the inside of the fume hood body 1 for cleaning the inside of the tempered explosion-proof glass door 14.
[0016] After each experiment and a period of settling, the cleaner can manually lift the tempered explosion-proof glass door 14 and store it. During this process, the cleaning component B4 contacts the inner surface of the tempered explosion-proof glass door 14 and performs cleaning. When the bottom of the tempered explosion-proof glass door 14 rises above the cleaning component B4, the cleaning of the inside of the tempered explosion-proof glass door 14 is complete. At this point, the cleaner only needs to use cleaning tools to clean the surface of the cleaning component B4. Subsequently, because the tempered explosion-proof glass door 14 is lifted and opened, the opening space expands. At this time, the cleaner can spray cleaning agent on the three inner surfaces of the fume hood body 1, and then place a cleaning cloth... Place the cleaning component A3 on the bottom inner side of the fume hood body 1, and place it against the bottom of the three sides. Then, manually pull down the cleaning component A3 to scrape and clean the three sides of the inner side of the fume hood body 1, bringing the residue and cleaning agent down with it. At this time, the cleaning cloth placed below can collect the dripping substances, and then take them out for cleaning. Finally, clean the bottom inner side of the fume hood body 1 to complete the overall cleaning operation. At the same time, during the maintenance of the equipment after a period of use, the space between the fume hood body 1 and the maintenance cabinet component 2, where electronic components are placed, can be quickly opened through the maintenance cabinet component 2 to facilitate maintenance operations.
[0017] Reference Figure 2 , Figure 3 and Figure 4 The maintenance cabinet assembly 2 includes a fixed column 21, which is fixedly installed on the inner edge of the fume hood body 1. A back door 22 and a side door 25 are rotatably installed on the two inner sides of the fixed column 21, respectively. A rotating column A23 is rotatably installed on the outer side of the back door 22. A baffle is installed on the outer side of the rotating column A23. The baffle is slidably installed on the inner side of the bracket 24. The bracket 24 is fixedly installed on the outer side of the fume hood body 1. A threaded column 27 is rotatably installed on the inner side of the side door 25. A rotating column B26 is fixedly installed at the end of the threaded column 27, located on the outer side of the fume hood body 1. A retaining strip 28 is fixedly installed at the other end of the threaded column 27, located on the inner side of the fume hood body 1, and slidably connected to the inner side of the fume hood body 1. A cavity is provided between the fume hood body 1 and the maintenance cabinet assembly 2. Control and exhaust elements are installed in the cavity.
[0018] When maintenance is required, the electronic components are placed inside the cavity formed by the fume hood body 1 and the maintenance cabinet assembly 2. The back door 22 or the side door 25 can be opened separately. When opening the back door 22, simply rotate the rotating column A23 to disengage the retaining strip from the bracket 24. At the same time, when opening the side door 25, rotate the two rotating columns B26 so that the arrows on the rotating columns B26 point to the corresponding side of the fume hood body 1 and the side door 25. This will disengage the retaining strip 28 from the inside of the fume hood body 1 and open the side door 25. This simple, flexible and quick opening method facilitates maintenance work.
[0019] Reference Figure 1 and Figure 6 The cleaning component A3 includes an adhesive frame 31, which is slidably disposed inside the fume hood body 1. A magnetic strip frame 32 is fixedly disposed on the outside of the adhesive frame 31, which is also slidably disposed inside the fume hood body 1. A connecting frame 33 is fixedly disposed inside the adhesive frame 31, and a handle 34 is fixedly disposed at the bottom of the outside of the connecting frame 33. The inner side of the adhesive frame 31 is inclined.
[0020] When cleaning the three inner sides of the fume hood body 1, after spraying the cleaning agent on the inner side, simply hold the handle 34 and slowly pull it downwards. At this time, under the magnetic attraction between the magnetic strip frame 32 and the inner side of the fume hood body 1, the adhesive frame 31 slowly slides down from the top, while its inclined bottom surface scrapes the inner side of the fume hood body 1, thereby achieving the effect of simultaneous cleaning.
[0021] Reference Figure 1 and Figure 5 The cleaning component B4 includes a warning strip 41, which is fixedly installed inside the fume hood body 1. A metal sheet 42 is fixedly installed at the bottom of the warning strip 41, and a microfiber wrapping strip 43 is fixedly installed at the bottom of the outer side of the metal sheet 42. The microfiber wrapping strip 43 is slidably installed on the inner surface of the tempered explosion-proof glass door 14.
[0022] When the tempered explosion-proof glass door 14 is lifted, the inner glass surface of the tempered explosion-proof glass door 14 comes into contact with the microfiber strip 43. At the same time, due to the deformation elasticity of the metal sheet 42, the microfiber strip 43 and the glass surface of the tempered explosion-proof glass door 14 will be driven to have an up-and-down impact, thereby generating a certain friction between the surface of the microfiber strip 43 and the glass surface of the tempered explosion-proof glass door 14, thereby improving the cleaning effect of the microfiber strip 43 on the inner glass surface of the tempered explosion-proof glass door 14.
[0023] Reference Figure 5 A groove 15 is fixedly provided on the outer side of the tempered explosion-proof glass door 14, and an infrared sensor is provided on the inner side of the tempered explosion-proof glass door 14 corresponding to the groove 15.
[0024] When the tempered explosion-proof glass door 14 is raised or lowered, it is operated through the groove 15. When the bottom surface of the tempered explosion-proof glass door 14 is higher than the warning strip 41, the infrared sensor sends a signal indicating that the preset height has been reached. At the same time, the height of the tempered explosion-proof glass door 14 is raised so that the opening is wide enough to clean the inside of the fume hood body 1, thus providing a signal prompt.
[0025] In summary, the fume hood disclosed in this application, which is easy to maintain, allows the cleaner to manually lift the tempered explosion-proof glass door 14 and store it after each experiment and a period of rest. During this process, the cleaning component B4 contacts the inner surface of the tempered explosion-proof glass door 14 and performs cleaning. When the bottom of the tempered explosion-proof glass door 14 is raised above the cleaning component B4, the cleaning of the inside of the tempered explosion-proof glass door 14 is complete. At this point, the cleaner only needs to use cleaning tools to clean the surface of the cleaning component B4. Subsequently, because the tempered explosion-proof glass door 14 is lifted and opened, the opening space expands. At this time, the cleaner can spray cleaning agent on the three inner surfaces of the fume hood body 1 and then place a cleaning cloth on the fume hood. The cleaning component A3 is placed on the inner bottom surface of the fume hood body 1 and attached to the bottom of the three sides. Then, manually pulling down the cleaning component A3 allows it to scrape and clean the three inner surfaces of the fume hood body 1, carrying away residue and cleaning agent. A cleaning cloth placed below collects any dripping substances, which can then be removed for cleaning. Finally, cleaning the inner bottom surface of the fume hood body 1 completes the overall cleaning operation. Simultaneously, during periodic maintenance, the space between the fume hood body 1 and the maintenance cabinet component 2, where electronic components are placed, can be quickly opened through the maintenance cabinet component 2 for easy maintenance. When maintenance is required, the different cavities formed by the fume hood body 1 and the maintenance cabinet component 2 can be used to place the electronic components separately. To open either the back door 22 or the side door 25, simply rotate the rotating column A23 to disengage the retaining strip from the bracket 24. Similarly, to open the side door 25, rotate both rotating columns B26 so that the arrows on them point towards the corresponding side of the fume hood body 1 and the side door 25. This disengages the retaining strip 28 from the inside of the fume hood body 1, allowing the side door 25 to open. This simple and flexible opening method facilitates maintenance. When cleaning the three inner surfaces of the fume hood body 1, after spraying cleaning agent onto the inner surfaces, simply hold the handle 34 and slowly pull downwards. At this time, under the magnetic attraction between the magnetic strip bracket 32 and the inside of the fume hood body 1, the mounting bracket 31 slowly slides downwards from the top. Simultaneously, its inclined bottom surface scrapes the inside of the fume hood body 1, achieving a simultaneous cleaning effect. When the tempered explosion-proof glass door 14 is lifted, the inner glass surface of the tempered explosion-proof glass door 14 contacts the microfiber strip 43. Due to the elasticity of the metal sheet 42, the microfiber strip 43 and the glass surface of the tempered explosion-proof glass door 14 are subjected to vertical counter-current action, resulting in friction between the surface of the microfiber strip 43 and the glass surface of the tempered explosion-proof glass door 14. This enhances the cleaning effect of the microfiber strip 43 on the inner glass surface of the tempered explosion-proof glass door 14. When lifting or pulling the tempered explosion-proof glass door 14, it is operated through the groove 15. When the bottom surface of the tempered explosion-proof glass door 14 is higher than the warning strip 41...An infrared sensor emits a signal indicating that the preset height has been reached. Simultaneously, the tempered explosion-proof glass door 14 is raised to a sufficient opening to clean the interior of the fume hood body 1, thus providing a signal indication.
