Description

Technical Field

[0001] This utility model belongs to the field of trash can technology, specifically a negative pressure epidemic prevention trash can. Background Technology

[0002] Epidemic prevention trash cans are waste collection containers specifically designed for the prevention and control of infectious diseases. They reduce hand contact and the risk of cross-infection through contactless operation (such as foot-operated opening, infrared sensing, or facial recognition). Their sealed structure prevents waste exposure, and some models have built-in ultraviolet lamps or disinfectant spray devices to kill viruses inside the can. Applications cover medical institutions (such as fever clinics and quarantine sites), public places (airports, train stations, schools), and communities. They are particularly suitable for handling medical waste such as masks and protective clothing during peak epidemic periods, as well as collecting potentially pathogen-laden household waste in ordinary areas. Through a dual mechanism of physical isolation and active disinfection, these trash cans effectively block the spread of viruses through waste, becoming an important piece of equipment in the public health prevention and control system.

[0003] The existing garbage bags for epidemic prevention garbage bins have to be manually unfolded, which is extremely inconvenient and the unfolding effect is not good. It requires careful and smooth unfolding, which is time-consuming and laborious. In addition, it is easy to leave large gaps between the garbage bag and the bin wall, which not only affects the smoothness of garbage disposal but also makes it easy for odors to escape. Its use effect is not good. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a negative pressure epidemic prevention trash can, which effectively solves the problem that the existing epidemic prevention trash cans require manual unfolding of the trash bag, which is extremely inconvenient to operate and has a poor unfolding effect. It is also time-consuming and laborious to unfold the trash bag smoothly, and it is easy to leave a large gap between the trash bag and the can wall, which not only affects the smoothness of trash disposal but also makes it easy for odor to escape.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure epidemic prevention trash can, comprising an epidemic prevention trash can body, a base fixedly installed at the bottom of the epidemic prevention trash can body, a top cover movably installed at the top of the epidemic prevention trash can body, an ultraviolet lamp fixedly installed on one side of the top cover, a control panel fixedly installed on the other side of the top cover, a servo motor fixedly installed on one side of the bottom of the base via a support seat, air intake channels are provided on the four inner walls of the epidemic prevention trash can body, and an air intake nozzle is fixedly installed at the bottom of the epidemic prevention trash can body, air pipes are fixedly installed at the lower ends of the air intake nozzles and the four air intake channels, an exhaust valve is fixedly installed between the lower ends of the five air pipes, the exhaust valve is fixedly connected to the inside of the base via two support rods, and an installation hopper is fixedly installed at the bottom of the exhaust valve;

[0006] An impeller is installed inside the mounting bucket, and an exhaust fan is installed on the other side of the base. A dustproof net is installed on the inner wall of the other side of the base. A transmission component is installed at the output end of the servo motor. The transmission component is connected to the exhaust fan and the impeller. When the servo motor is running, it drives the exhaust fan and the impeller to rotate synchronously through the transmission component.

[0007] Preferably, the upper part of the main body of the epidemic prevention trash can is provided with a slot, a magnet is fixedly installed in the bottom of the slot, and an iron sheet is fixedly installed in the bottom of the pressure frame.

[0008] Preferably, the transmission assembly includes a rotating rod fixedly mounted on the output end of the servo motor, and the surface of the rotating rod is rotatably connected to the inner bottom of the base through three bearings.

[0009] Preferably, a shaft is fixedly installed at the end of the rotating rod away from the servo motor, the surface of the shaft is rotatably connected to the inside of the base through a bushing, and one end of the shaft is fixedly connected to the exhaust fan.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator inserts the garbage bag into the interior of the main body of the epidemic prevention garbage bin, then inserts the top opening of the garbage bag into the slot, and then inserts the pressure frame into the slot to press the top opening of the garbage bag tightly. At the same time, the magnet will attract the pressure frame through the iron sheet to ensure its fixation and sealing effect. Then, the operator opens the exhaust valve through the control panel and starts the servo motor to drive the rotating rod to rotate. When the rotating rod rotates, it drives the driven bevel gear to rotate through the active bevel gear. When the driven bevel gear rotates, it drives the impeller to rotate through the rotating shaft. The impeller draws the air out of the interior of the main body of the epidemic prevention garbage bin through five air pipes, four air ducts and air nozzles on the four sides and bottom of the garbage bag. Thus, the negative pressure makes the garbage bag stick tightly to the inner walls of the four sides of the main body of the epidemic prevention garbage bin, so that the garbage bag can be quickly and completely unfolded.

[0011] While the rotating rod is rotating, it also drives the exhaust fan to rotate through the shaft, thereby drawing the air into the base of the impeller and venting it away to prevent air backflow. Then, the exhaust valve is closed to maintain a negative pressure effect inside the main body of the epidemic prevention trash can. This allows the trash bag to be quickly and completely unfolded when the trash can is fitted with it, and makes the trash bag fit tightly against the can wall, reducing gaps and improving the smoothness of trash disposal.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 6The present invention comprises a hollow, open-top structure for a waste bin body 1. A base 2 is fixedly installed at the bottom of the waste bin body 1, ensuring stable contact with the ground and guaranteeing the vertical stability of the waste bin body 1. A top cover 3 is movably installed at the top of the waste bin body 1, sealing the top opening. An ultraviolet lamp 4 is fixedly installed on one side of the top cover 3, disinfecting the interior of the waste bin body 1. A control panel 5 is fixedly installed on the other side of the top cover 3. A servo motor for outputting rotational power is fixedly installed on one side of the bottom of the base 2 via a support 14. The servo motor 15, exhaust valve 13, and ultraviolet lamp 4 are all electrically connected to the control panel 5 via flexible wires. Air intake channels 9 are provided on the inner walls of the four sides of the main body 1 of the epidemic prevention garbage bin. An air intake nozzle 13 is fixedly installed at the bottom of the main body 1 of the epidemic prevention garbage bin. Air pipes 16 are fixedly installed at the lower ends of the air intake nozzles 13 and the four air intake channels 9. An exhaust valve 10 is fixedly installed between the lower ends of the five air pipes 16. The exhaust valve 10 can be opened to exhaust air. The exhaust valve 10 is fixedly connected to the inside of the base 2 through two support rods 11 to ensure the stability of the exhaust valve 10. An installation bucket 12 is fixedly installed at the bottom of the exhaust valve 10.

[0023] The inside of the mounting bucket 12 is equipped with an impeller 19, and the other side of the base 2 is equipped with an exhaust fan 17. When the exhaust fan 17 and the impeller 19 rotate, they can draw out the air inside the main body 1 of the epidemic prevention garbage can. The other side of the inner wall of the base 2 is equipped with a dustproof net 18, which can prevent external dust from entering. The output end of the servo motor 15 is equipped with a transmission component, which is connected to the exhaust fan 17 and the impeller 19. When the servo motor 15 runs, it drives the exhaust fan 17 and the impeller 19 to rotate synchronously through the transmission component. The upper part of the main body 1 of the epidemic prevention garbage can is equipped with a slot 6, and a pressure frame 8 is installed in the slot 6. The pressure frame 8 can press the upper part of the garbage bag into the slot 6. A magnet 7 is fixedly installed in the bottom of the slot 6, and an iron plate is fixedly installed in the bottom of the pressure frame 8, so that the magnet 7 can attract the pressure frame 8 through the iron plate to improve the fixing effect of the garbage bag.

[0024] In use, the operator inserts the garbage bag into the body 1 of the epidemic prevention garbage bin, then inserts the top opening of the garbage bag into the slot 6, and then inserts the pressure frame 8 into the slot 6 to press the top opening of the garbage bag tightly. At the same time, the magnet 7 will attract the pressure frame 8 through the iron sheet to ensure its fixation and sealing effect. Then, the operator opens the exhaust valve 10 through the control panel 5 and starts the servo motor 15 to drive the transmission component to operate. When the transmission component operates, it draws out the air inside the body 1 of the epidemic prevention garbage bin, thereby using negative pressure to make the garbage bag stick tightly to the four inner walls of the body 1 of the epidemic prevention garbage bin, so that the garbage bag can be quickly and completely unfolded.

[0025] At the same time, the transmission component will also expel the air drawn into the base to prevent air backflow, and then close the exhaust valve 10 to maintain a negative pressure effect inside the main body 1 of the epidemic prevention trash can; so that when the trash bag is put on the epidemic prevention trash can, it can be quickly and completely unfolded through negative pressure, and the trash bag is tightly attached to the wall of the can, reducing gaps and improving the smoothness of trash disposal.

[0026] The transmission assembly includes a rotating rod 20 fixedly mounted on the output end of the servo motor 15. The surface of the rotating rod 20 is rotatably connected to the inner bottom of the base 2 via three bearing seats 25, which ensure the stability of the rotation of the rotating rod 20. A driving bevel gear 21 is fixedly mounted on the surface of the rotating rod 20 and inside the mounting bucket 12. A driven bevel gear 22 is meshed on one side of the surface of the driving bevel gear 21. The engagement of the driven bevel gear 22 and the driving bevel gear 21 can change the direction of rotational transmission. A rotating shaft 23 is fixedly mounted on the top of the driven bevel gear 22. The top end of the rotating shaft 23 is fixedly connected to the impeller 19. The surface of the rotating shaft 23 is rotatably connected to the inside of the mounting bucket 12 via a bearing 24, which ensures the stability of the rotation of the rotating shaft 23 and the impeller 19.

[0027] The operator opens the exhaust valve 10 through the control panel 5 and starts the servo motor 15 to drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, it drives the driven bevel gear 22 to rotate through the active bevel gear 21. When the driven bevel gear 22 rotates, it drives the impeller 19 to rotate through the rotating shaft 23. This causes the impeller 19 to draw out the air from the four sides and bottom of the garbage bag through five air pipes 16, four air ducts 9 and air nozzles 13.

[0028] A shaft 26 is fixedly installed at the end of the rotating rod 20 away from the servo motor 15. The surface of the shaft 26 is rotatably connected to the inside of the base 2 through the bushing 27. The bushing 27 ensures the stability of the rotation of the shaft 26 and the rotating rod 20. One end of the shaft 26 is fixedly connected to the exhaust fan 17.

[0029] As the rotating rod 20 rotates, it also drives the exhaust fan 17 to rotate via the shaft 26, thereby drawing the air from the impeller 19 into the base and removing it.
