Description

Technical Field

[0001] This utility model relates to the field of laboratory ventilation equipment technology, and in particular to a laboratory energy-saving ventilation equipment. Background Technology

[0002] Laboratories are places for scientific research, experimental operations, and analytical testing. Energy-efficient ventilation equipment for laboratories is a ventilation system specifically designed for laboratories, aiming to achieve efficient ventilation while reducing energy consumption through optimized design and advanced technology. Various chemical and biological experiments are frequently conducted in laboratories, generating harmful gases and particulate matter. Energy-efficient ventilation equipment can effectively remove these pollutants, ensuring air quality within the laboratory and protecting the health of laboratory personnel; therefore, energy-efficient ventilation equipment for laboratories is used.

[0003] A search revealed Chinese Patent Publication No. CN213901313U, which discloses an energy-saving and environmentally friendly laboratory ventilation device. The device includes an outer body. A first groove is formed in the inner bottom wall of the outer body. A slider is slidably connected to the inner surface of the first groove. A water tank is fixedly connected to the upper surface of the slider. A partition is provided between the inner sidewalls of the water tank. A through-hole is formed on the surface of the partition. A duct is inserted into one side of the outer body, and a fan is fixedly connected to one side of the duct. A second groove is formed in the inner sidewall of the outer body. A filter screen is slidably connected to the inner surface of the second groove. A cavity is formed on one side of the filter screen, and a snap-fit ​​structure is provided inside the cavity. An insertion hole is formed on one side of the second groove, and a pressing structure is formed on one side of the insertion hole.

[0004] In the aforementioned utility model, through the arrangement of the first sliding groove, slider, water tank, partition, through hole, and fan, during use, the door is opened, the water tank is pulled outward, causing the slider to slide outward along the first sliding groove, then ice is placed on the partition, the door is closed, and the fan is started. The fan generates negative pressure, allowing outdoor air to enter the interior of the exterior. The ice melts, forming cold air, which is filtered by the filter screen, sterilized by the ultraviolet germicidal lamp, and then discharged from the vent louvers, providing ventilation and heat dissipation to the room and humidifying the air. However, in actual use, the ultraviolet germicidal lamp is prone to damage after long-term use. When maintenance and replacement are required, it is difficult to disassemble and maintain it separately, resulting in high maintenance costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a laboratory energy-saving ventilation device, which aims to improve the problem of difficulty in disassembling, maintaining and replacing ultraviolet disinfection lamps separately.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a laboratory energy-saving ventilation device, comprising a body, an ultraviolet disinfection lamp slidably connected inside the body, a push block fixedly connected to the outer wall of the ultraviolet disinfection lamp, a locking block slidably connected to the outer wall of the push block, the locking block slidably connected to the outer wall of the locking block inside the body, a limit strip slidably connected inside the locking block, the limit strip fixedly connected to the outer wall of the limit strip inside the body, a sliding column fixedly connected to the outer wall of the locking block, a pull tab fixedly connected to the outer wall of the sliding column, a fixing plate slidably connected to the outer wall of the sliding column, the fixing plate fixedly connected to the outer wall of the fixing plate inside the body, a first spring fixedly connected to the outer wall of the locking block, the first spring fixedly connected to the outer wall of the fixing plate, and a protective component provided inside the body.

[0007] The above technical solution allows for the sterilization of air drawn into the machine body by installing an ultraviolet disinfection lamp. The ultraviolet disinfection lamp can be installed by a push block. When the locking block is squeezed by the push block, it will drive the sliding column to slide synchronously and squeeze the first spring. Through the special shape design of the locking block, it can be squeezed by the push block first and then locked in the opposite direction to the push block, thus completing the installation of the ultraviolet disinfection lamp.

[0008] As a further description of the above technical solution:

[0009] The protective assembly includes a door, the outer wall of which is slidably connected to the inside of the machine body, and a handle is fixedly connected to the outer wall of the door.

[0010] Through the above technical solution: the machine door serves as a fixed handle, which makes it easy to open the machine door and perform maintenance on the inside of the machine.

[0011] As a further description of the above technical solution:

[0012] A baffle plate is fixedly connected inside the machine body, and a fan is installed inside the machine body.

[0013] The above technical solution involves drawing in air from the laboratory by starting the fan, allowing the air to pass through the baffle and enter the machine's interior, where it is then disinfected and purified for subsequent ventilation of the laboratory.

[0014] As a further description of the above technical solution:

[0015] A filter box is fixedly connected to the outer wall of the machine body. Multiple exhaust holes are opened inside the filter box, and a filter plate is slidably connected inside the filter box.

[0016] The above technical solution allows for the following: the filter box filters the disinfected air, the exhaust vent discharges the purified air, and the filter plate adsorbs, filters, and purifies impurities in the air.

[0017] As a further description of the above technical solution:

[0018] A fixing block is fixedly connected to the outer wall of the filter box, a sliding plate is slidably connected inside the fixing block, a fixing piece is fixedly connected to the lower surface of the sliding plate, and the outer wall of the fixing piece is slidably connected inside the fixing block.

[0019] Through the above technical solution: the filter box has the function of fixing the fixed block, and the sliding action of the slide plate can drive the fixed plate to slide synchronously. The fixed block plays a supporting role for the fixed plate, which can make the fixed plate slide stably against the inner wall of the fixed block.

[0020] As a further description of the above technical solution:

[0021] One end of a telescopic rod is fixedly connected to the outer wall of the fixing plate, and the other end of the telescopic rod is fixedly connected to the inside of the fixing block. A second spring is fixedly connected to the outer wall of the fixing plate, and the outer wall of the second spring is fixedly connected to the inside of the fixing block.

[0022] The above technical solution works as follows: when the telescopic rod is pushed by the fixed plate, it will extend and retract, which will also compress the second spring. The second spring will rebound and push the fixed plate to slide in the opposite direction.

[0023] As a further description of the above technical solution:

[0024] The outer wall of the fixing plate is fixedly connected to a locking post, the outer wall of the locking post is slidably connected to the inside of the filter box, and the outer wall of the locking post is slidably connected to the inside of the filter plate and the fixing block.

[0025] The above technical solution uses a retaining post to restrict the position of the filter plate inside the filter box. By sliding the retaining post into or out of the filter box, the filter plate can be installed or removed. When the retaining post is retracted into the filter box, the restriction on the filter plate is released.

[0026] As a further description of the above technical solution:

[0027] A push plate is fixedly connected to the lower surface of the filter plate, and the outer wall of the push plate is slidably connected to the inside of the filter box. A third spring is fixedly connected to the lower surface of the push plate, and the outer wall of the third spring is fixedly connected to the inside of the filter box.

[0028] With the above technical solution, when the push plate is not restricted, it will also release the pressure on the third spring, and then the push plate can slide in the opposite direction through the rebound action of the third spring, so as to push the filter plate out of the filter box, and remove the filter plate for cleaning and replacement.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the fan is started to draw air into the machine body and disinfect it through the ultraviolet disinfection lamp. The ultraviolet disinfection lamp can be installed or removed by the cooperation of the push block, the locking block, the limiting strip, the sliding column, the pulling plate and the first spring, so as to facilitate the installation and use of the ultraviolet disinfection lamp and facilitate individual maintenance and replacement.

[0031] 2. In this utility model, the sliding plate drives the fixed plate to slide. Through the cooperation between the telescopic rod, the second spring, the locking post, the push plate and the third spring, the filter plate can be installed or removed by sliding the locking post into or out of the filter plate. This makes it easy to remove the filter plate for cleaning and replacement, ensuring the efficient operation of the ventilation system and reducing energy consumption. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: a laboratory energy-saving ventilation device, including a body 1, an ultraviolet disinfection lamp 2 slidably connected inside the body 1, a push block 3 fixedly connected to the outer wall of the ultraviolet disinfection lamp 2, a locking block 4 slidably connected to the outer wall of the push block 3, the outer wall of the locking block 4 slidably connected to the inside of the body 1, a limit strip 5 slidably connected inside the locking block 4, the outer wall of the limit strip 5 fixedly connected to the inside of the body 1, a sliding column 6 fixedly connected to the outer wall of the locking block 4, a pull tab 7 fixedly connected to the outer wall of the sliding column 6, a fixing plate 8 slidably connected to the outer wall of the sliding column 6, the outer wall of the fixing plate 8 fixedly connected to the inside of the body 1, a first spring 9 fixedly connected to the outer wall of the locking block 4, the outer wall of the first spring 9 fixedly connected to the outer wall of the fixing plate 8, and a protective component 10 provided inside the body 1;

[0040] Specifically, the ultraviolet disinfection lamp 2, installed inside the machine body 1, can sterilize and disinfect the air in the laboratory. The ultraviolet disinfection lamp 2 fixes the push block 3, allowing it to be installed inside the machine body 1. When the push block 3 slides inside the machine body 1, it exerts pressure on the locking block 4. The limiting strip 5, fixed inside the machine body 1, limits the sliding of the locking block 4, preventing it from shifting during sliding. The locking block 4 fixes the sliding column 6, allowing the sliding column 6 to move through the sliding of the locking block 4. The sliding plate 8 is fixed inside the body 1 and supports the sliding column 6. The sliding column 6 fixes the pull piece 7. The ultraviolet disinfection lamp 2 can be disassembled by pulling the pull piece 7. The first spring 9 is set between the fixed plate 8 and the locking block 4. It will be squeezed by the sliding of the locking block 4. Due to the shape design of the locking block 4, it will initially be squeezed by the push block 3. Then, it will slide in the opposite direction due to the locking of the push block 3. The rebound of the first spring 9 can make the locking block 4 lock the push block 3 in the opposite direction, thereby completing the installation of the ultraviolet disinfection lamp 2.

[0041] Reference Figure 1 The protective component 10 includes a door 1001, the outer wall of which is slidably connected to the inside of the body 1, and a handle 1002 is fixedly connected to the outer wall of the door 1001.

[0042] Specifically, the machine door 1001 facilitates the inspection and maintenance of the interior of the machine body 1. The machine door 1001 serves to fix the handle 1002, and the machine door 1001 can be opened by pulling the handle 1002.

[0043] Reference Figure 1 and Figure 2 A baffle plate 11 is fixedly connected inside the body 1, and a fan 23 is installed inside the body 1;

[0044] Specifically, the baffle 11 allows air from inside the laboratory to enter the interior of the machine body 1, and the fan 23 draws in the air, purifying it and then ventilating it.

[0045] Reference Figure 1 and Figure 4 A filter box 12 is fixedly connected to the outer wall of the machine body 1. Multiple exhaust holes 13 are provided inside the filter box 12. A filter plate 14 is slidably connected inside the filter box 12. A fixing block 15 is fixedly connected to the outer wall of the filter box 12. A sliding plate 16 is slidably connected inside the fixing block 15. A fixing piece 17 is fixedly connected to the lower surface of the sliding plate 16. The outer wall of the fixing piece 17 is slidably connected inside the fixing block 15. One end of a telescopic rod 18 is fixedly connected to the outer wall of the fixing piece 17. The other end of the telescopic rod 18 is fixedly connected to the inside of the fixing block 15. A second spring 19 is fixedly connected to the outer wall of the fixing piece 17. The outer wall of the second spring 19 is fixedly connected to the inside of the fixing block 15. A locking post 20 is fixedly connected to the outer wall of the fixing piece 17. The outer wall of the locking post 20 is slidably connected inside the filter box 12. The outer wall of the locking post 20 is slidably connected inside the filter plate 14 and the fixing block 15.

[0046] Specifically, the filter box 12 is fixed inside the body 1, which serves to fix the fixing block 15. The purified air can be discharged through the exhaust port 13, ventilating the laboratory. The fixing block 15 supports the sliding plate 16, which in turn fixes the fixing piece 17. The fixing piece 17 then fixes the telescopic rod 18. The telescopic rod 18 is positioned between the fixing piece 17 and the fixing block 15, allowing the fixing piece 17 to slide stably within the fixing block 15 via the sliding plate 16. The telescopic rod 18 will also extend and retract due to the sliding of the fixed plate 17. The second spring 19 is set between the fixed plate 17 and the fixed block 15. It will also be squeezed due to the sliding of the fixed plate 17. The fixed plate 17 plays a role in fixing the locking post 20, thereby causing the locking post 20 to slide synchronously. When the locking post 20 slides out of the filter plate 14, it will release the restriction on the filter plate 14. Conversely, the rebound action of the second spring 19 can push the locking post 20 back into the filter plate 14, thereby limiting and fixing the position of the filter plate 14 and the filter box 12.

[0047] Reference Figure 4 A push plate 21 is fixedly connected to the lower surface of the filter plate 14. The outer wall of the push plate 21 is slidably connected to the inside of the filter box 12. A third spring 22 is fixedly connected to the lower surface of the push plate 21. The outer wall of the third spring 22 is fixedly connected to the inside of the filter box 12.

[0048] Specifically, the filter box 12 supports the push plate 21. When the filter plate 14 is stuck inside the filter box 12, it will press the position of the push plate 21, thereby compressing the third spring 22. Conversely, when the filter plate 14 is no longer restricted, the third spring 22 will rebound, thereby causing the filter plate 14 to slide out of the filter box 12 by the pushing action of the push plate 21.

[0049] Working principle: The machine body 1 is placed in the laboratory. When the equipment is needed, the ultraviolet disinfection lamp 2 is installed and used. The ultraviolet disinfection lamp 2 is slid into the machine body 1 through the push block 3. The push block 3 will squeeze the locking block 4, causing the locking block 4 to slide through the limit strip 5. When the locking block 4 slides, it will drive the sliding column 6 on the outer wall to slide at the same time. During the sliding process, the locking block 4 will squeeze the first spring 9. When the push block 3 and the locking block 4 are in contact, the rebound action of the first spring 9 can push the locking block 4 in the opposite direction to lock the push block 3. Thus, the ultraviolet disinfection lamp 2 can be installed in the machine body 1 for disinfection treatment. This achieves the effect of facilitating the installation and use of the ultraviolet disinfection lamp 2, and facilitating individual maintenance and replacement, reducing maintenance costs.

[0050] Starting the fan 23 draws laboratory air into the machine body 1 through the baffle 11. The ultraviolet disinfection lamp 2 sterilizes and disinfects the air. The sterilized air then enters the filter box 12 for adsorption and filtration. After passing through the filter plate 14, it is discharged through the exhaust port 13. When the filter plate 14 needs cleaning or replacement, simply pull the sliding plate 16. The sliding plate 16 will cause the fixing plate 17 to slide. During this sliding process, the fixing plate 17 will extend and retract the telescopic rod 18, simultaneously compressing the second spring 19. The sliding of the fixing plate 17 will also cause the locking pin 20 to slide out of the filter plate 14. Internally, when the filter plate 14 is no longer restricted by the retaining post 20, it no longer presses against the push plate 21 and the third spring 22. The rebound action of the third spring 22 can push the push plate 21 to slide in the opposite direction, thereby pushing the filter plate 14 out of the filter box 12. This facilitates the removal, cleaning, and replacement of the filter plate 14, ensuring the efficient operation of the ventilation system and reducing energy consumption. This equipment not only facilitates the installation and use of the ultraviolet disinfection lamp 2 and allows for individual maintenance and replacement, reducing maintenance costs, but also facilitates the removal, cleaning, and replacement of the filter plate 14, ensuring the efficient operation of the ventilation system and reducing energy consumption.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
