Description

Technical Field

[0001] This invention belongs to the technical field of medical waste bins, specifically a medical sterilization waste bin. Background Technology

[0002] Medical waste bins are containers for holding waste that is directly or indirectly infectious, toxic, or otherwise hazardous, generated by medical and health institutions during medical treatment, prevention, healthcare, and other related activities. Since some medical waste is infectious and toxic, it needs to be disinfected. To facilitate disinfection during use, existing technologies generally install ultraviolet disinfection lamps on the inside of the bin lid. When the lid is on the bin, the hazardous waste inside can be disinfected.

[0003] While the aforementioned existing technologies can effectively disinfect medical waste, the trash cans need to be used frequently, and the lid needs to be opened each time. When the lid is opened, the ultraviolet disinfection lamp will directly irradiate the skin and eyes of medical personnel, thereby causing damage to the human body. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a medical sterilization trash can that effectively solves the problem that the ultraviolet disinfection lamp can directly irradiate the human body when the lid is opened, thus causing injury.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a medical sterilization trash can, including an outer bucket, a sealing ring fixedly connected to the top of the outer bucket, an inner bucket inside the outer bucket, a lid rotatably connected to the top of the outer bucket, a shielding mechanism on the side of the lid near the outer bucket, a fixing mechanism on the shielding mechanism, and a driving mechanism between the outer bucket and the lid.

[0006] The shielding mechanism includes a placement frame fixed to the side of the bucket lid near the outer bucket. Inside the placement frame is a receiving frame, and inside the receiving frame is an ultraviolet disinfection lamp. Inside the placement frame is a baffle that slides. The ultraviolet disinfection lamp is located between the baffle and the bucket lid. A guide post is fixedly connected between the placement frame and the bucket lid. A guide block is movably sleeved on the outside of the guide post. Two connecting posts are symmetrically fixedly connected between the guide block and the baffle. The placement frame is located between the two connecting posts. An inner plate is fixedly installed inside the outer bucket. An adjusting rod is rotatably connected to the top of the inner plate. The top of the adjusting rod is rotatably connected to the outside of the guide block.

[0007] Preferably, the driving mechanism includes two upright plates symmetrically installed inside the outer barrel, both upright plates being located below the inner plate, and each upright plate having a movable rod rotatably connected to the side of the inner barrel near the inner plate, with the top of each movable rod being rotatably connected to the barrel lid.

[0008] Preferably, a U-shaped plate is fixedly connected to the inner bottom wall of the outer barrel, and two columns are symmetrically fixedly connected between the U-shaped plate and the inner plate. The two columns are movably sleeved on the outside of the two columns, and a return spring is fixedly connected between the two columns and the U-shaped plate. The two return springs are respectively sleeved on the outside of the two columns.

[0009] Preferably, the inner side of the U-shaped plate is rotatably connected to an inner shaft, and a sleeve plate is fixedly sleeved on the middle of the outer side of the inner shaft. A pedal located on the outer side of the outer barrel is fixedly installed on the top of the sleeve plate. An avoidance groove is provided on the outer barrel, and the sleeve plate is slidably connected to the avoidance groove.

[0010] Preferably, an L-shaped rod is fixedly connected between the U-shaped plate and the outer barrel, a lifting plate is movably sleeved on the outer side of the L-shaped rod, a drive rod is rotatably connected to the top of the sleeve, and the top of the drive rod is rotatably connected to the lifting plate.

[0011] Preferably, a bracket is fixedly installed on the outer side of the U-shaped plate, and an abutment roller is rotatably connected to the bracket, with the bottom of the sleeve plate abutting against the abutment roller.

[0012] Preferably, the inner tub and the outer tub are symmetrically rotatably connected by two rotating shafts, both of which are located between two upright plates, and the lifting plate is located between the two rotating shafts. Gears are fixedly installed on the outer side of each of the two rotating shafts. Two active gear plates are symmetrically fixedly connected to the outer side of the lifting plate, and the two active gear plates are respectively meshed with the two gears. Driven gear plates are fixedly connected to the side of each of the two upright plates that are close to each other, and the two driven gear plates are respectively meshed with the two gears.

[0013] Preferably, the fixing mechanism includes a U-shaped rod fixed to the outside of the receiving frame. Two sliders are symmetrically and movably sleeved on the outside of the U-shaped rod. Each slider has a limiting wheel that fits against the receiving frame. A plug rod is fixedly connected to the side of each slider away from the receiving frame. Two positioning cylinders are symmetrically and fixedly connected to the outside of the placement frame. The two plug rods are respectively inserted into the two positioning cylinders.

[0014] Preferably, a sleeve block is fixedly sleeved on the middle of the outer side of the U-shaped rod. The sleeve block is fixed to the outer side of the receiving frame and is located between two sliders. Compression springs are fixedly connected between the two sliders and the sleeve block, and the two compression springs are sleeved on the outer side of the U-shaped rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, through the cooperation of the placement frame, the receiving frame, and the ultraviolet disinfection lamp, can disinfect and sterilize the inside of the outer bucket when the lid is closed. Through the cooperation of the inner plate, the adjusting rod, the guide block, and the guide column, when the lid is rotated open, it can drive the two connecting columns to move, thereby allowing the baffle to move and insert into the placement frame, which can then block the light emitted by the ultraviolet disinfection lamp, thus avoiding direct irradiation of the ultraviolet disinfection lamp and causing harm to the human body.

[0017] 2. This invention, through the cooperation between the sleeve plate, the inner shaft, and the drive rod, facilitates the sliding of the lifting plate downward along the L-shaped rod when the pedal is stepped on. The cooperation between the active gear plate and the gear, as well as the rotating shaft and the driven gear plate, facilitates the upward sliding of the two upright plates along the two columns, causing both return springs to deform. This deformation, along with the movable rod, facilitates the rotation of the lid to open. When the pedal is released, the two return springs reset, causing the two upright plates to slide downward along the two columns, thus allowing the lid to rotate and close. This eliminates the need to manually open the lid to dispose of garbage, preventing bacterial contamination.

[0018] 3. This invention facilitates the movement of two insert rods into two positioning cylinders through the cooperation between the U-shaped rod and the slider, as well as the compression spring and the sleeve block. This allows the receiving frame to be inserted into the placement frame for fixation, thus facilitating the installation of the ultraviolet disinfection lamp. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1, by Figures 1-7 The present invention relates to a medical sterilization trash can, comprising an outer bucket 1, a sealing ring 6 fixedly connected to the top of the outer bucket 1, an inner bucket 7 inside the outer bucket 1, a lid 5 rotatably connected to the top of the outer bucket 1, a shielding mechanism 2 provided on the side of the lid 5 near the outer bucket 1, a fixing mechanism 4 provided on the shielding mechanism 2, and a driving mechanism 3 provided between the outer bucket 1 and the lid 5. When the lid 5 is closed, it fits tightly with the sealing ring 6, thereby preventing bacteria and odors inside the outer bucket 1 from spreading into the air.

[0031] In Example 2, based on Example 1, the shielding mechanism 2 includes a placement frame 201 fixed to the side of the bucket lid 5 near the outer bucket 1. A receiving frame 209 is placed inside the placement frame 201, and an ultraviolet disinfection lamp 208 is installed inside the receiving frame 209. A baffle 207 is slidably connected inside the placement frame 201. The ultraviolet disinfection lamp 208 is located between the baffle 207 and the bucket lid 5. A guide post 206 is fixedly connected between the placement frame 201 and the bucket lid 5. A guide block 203 is movably sleeved on the outside of the guide post 206. Two connecting posts 202 are symmetrically fixedly connected between the guide block 203 and the baffle 207. The placement frame 201 is located between the two connecting posts 202. An inner plate 204 is fixedly installed inside the outer bucket 1. An adjusting rod 205 is rotatably connected to the top of the inner plate 204. The top of the adjusting rod 205 is rotatably connected to the outside of the guide block 203.

[0032] When the lid 5 is closed, the baffle 207 is located outside the placement frame 201, so that the ultraviolet disinfection lamp 208 can disinfect and sterilize the inside of the outer bucket 1. When the lid 5 is rotated open, it drives the adjusting rod 205 to move and drives the guide block 203 to slide along the guide post 206. Then, the baffle 207 is moved through the two connecting posts 202, so that the baffle 207 is inserted into the placement frame 201 to block the light emitted by the ultraviolet disinfection lamp 208, and finally avoids direct irradiation of the ultraviolet disinfection lamp 208 from causing human injury.

[0033] In embodiment three, based on embodiment one, the driving mechanism 3 includes two upright plates 301 symmetrically installed inside the outer tub 1. Both upright plates 301 are located below the inner plate 204. Each upright plate 301 has a movable rod 306 rotatably connected to its side near the inner tub 7. The top ends of both movable rods 306 are rotatably connected to the tub lid 5. A U-shaped plate 302 is fixedly connected to the inner bottom wall of the outer tub 1. Two uprights 307 are symmetrically fixedly connected between the U-shaped plate 302 and the inner plate 204. The two upright plates 301 are respectively movably sleeved... Two return springs 309 are fixedly connected to the outer sides of the two uprights 307 and the U-shaped plate 302. The two return springs 309 are respectively sleeved on the outer sides of the two uprights 307. An inner shaft 3010 is rotatably connected to the inner side of the U-shaped plate 302. A sleeve plate 303 is fixedly sleeved on the middle of the outer side of the inner shaft 3010. A pedal 304 located on the outer side of the outer barrel 1 is fixedly installed on the top of the sleeve plate 303. An clearance groove 8 is provided on the outer barrel 1. The sleeve plate 303 is slidably connected to the clearance groove 8. The U-shaped plate 302... An L-shaped round rod 3017 is fixedly connected to the outer tub 1. A lifting plate 305 is movably sleeved on the outer side of the L-shaped round rod 3017. A drive rod 3013 is rotatably connected to the top of the sleeve plate 303. The top of the drive rod 3013 is rotatably connected to the lifting plate 305. A bracket 3011 is fixedly installed on the outer side of the U-shaped plate 302. An abutment roller 3012 is rotatably connected to the bracket 3011. The bottom of the sleeve plate 303 abuts against the abutment roller 3012. Two rotating shafts 308 are symmetrically rotatably connected between the inner tub 7 and the outer tub 1. Both rotating shafts 308 are located between two vertical plates 301, and the lifting plate 305 is located between the two rotating shafts 308. Gears 3015 are fixedly installed on the outer side of both rotating shafts 308. Two active gear plates 3014 are symmetrically fixedly connected to the outer side of the lifting plate 305. The two active gear plates 3014 are respectively meshed with the two gears 3015. Driven gear plates 3016 are fixedly connected to the side of the two vertical plates 301 that are close to each other. The two driven gear plates 3016 are respectively meshed with the two gears 3015.

[0034] First, stepping on pedal 304 causes the sleeve plate 303 and inner shaft 3010 to rotate. This drives the lifting plate 305 to slide downwards along the L-shaped rod 3017 via drive rod 3013, and causes the two active gear plates 3014 to move downwards. Since the two active gear plates 3014 are respectively engaged with the two gears 3015, they drive the two rotating shafts 308 and the two gears 3015 to rotate. Since the two gears 3015 are respectively engaged with the two driven gear plates 3016, they drive the two upright plates 301 to slide upwards along the two columns 307. At this time, the two return springs 309 are stretched. Then, the two movable rods 306 drive the lid 5 to rotate and open, allowing garbage to be thrown into the outer bin 1. When the pedal 304 is released, the two return springs 309 return to their original position, causing the two upright plates 301 to slide downwards along the two columns 307. The two movable rods 306 drive the lid 5 to rotate and close, thus eliminating the need to manually open the lid 5 to avoid bacterial infection.

[0035] In Example 4, based on Example 1, the fixing mechanism 4 includes a U-shaped rod 401 fixed to the outside of the receiving frame 209. Two sliders 407 are symmetrically and movably sleeved on the outside of the U-shaped rod 401. Limiting wheels 403 that fit against the receiving frame 209 are installed on the outside of the two sliders 407. Insert rods 405 are fixedly connected to the side of the two sliders 407 away from the receiving frame 209. Two positioning cylinders 404 are symmetrically and fixedly connected to the outside of the placement frame 201. The two insert rods 405 are respectively inserted into the two positioning cylinders 404. A sleeve block 402 is fixedly sleeved on the middle of the outside of the U-shaped rod 401. The sleeve block 402 is fixed to the outside of the receiving frame 209 and is located between the two sliders 407. Compression springs 406 are fixedly connected between the two sliders 407 and the sleeve block 402. The two compression springs 406 are sleeved on the outside of the U-shaped rod 401.

[0036] First, slide both sliders 407 along the U-shaped rod 401, bringing them closer to the sleeve block 402. At the same time, both limit wheels 403 roll on the receiving frame 209 to ensure the stability of the sliders 407 during movement. Both compression springs 406 are compressed, and the two insertion rods 405 move closer to each other. Then, insert the receiving frame 209 into the placement frame 201 and release the two sliders 407. At this time, the two compression springs 406 return to their original positions, causing the two sliders 407 to slide along the U-shaped rod 401. Meanwhile, the two insertion rods 405 move away from each other until they are inserted into the two positioning cylinders 404, fixing the receiving frame 209 to the placement frame 201. Finally, the installation of the ultraviolet disinfection lamp 208 is completed.
