[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The isolation component provided in the present invention can prevent the transmission of pathogens caused by long-term exposure of hard sharp waste to the air. At the same time, medical staff do not need to manually operate the device when placing hard sharp waste into the device. When hard sharp waste needs to be discarded, the waste is directly placed into the box through the placement port. The waste will move along the material guide slope to the conveyor belt covered on the rotating rod. The rotating rod is driven to rotate to move the conveyor belt with the waste downward. The waste will move to the material guide plate under the movement of the material plate. After the waste is placed, the air pump connected to the second air guide pipe is started, and the air pump will transfer the second The gas in the airbag is drawn into the airtight cavity. At this time, the first partition installed on one side of the placement port will gradually close the placement port. When the placement port is completely closed, the second airbag is completely emptied, and the trigger button connected to its free end will synchronously contact the switch on the outside of the other air pump. At this time, the other air pump will draw out the gas in the air guide cavity to inflate the first airbag. Therefore, the pneumatic rod slidingly installed in the air guide cavity will slide along one end of the material guide plate together with the second partition, so that the waste on the material guide plate is transferred to the second partition and continues to fall under the action of gravity until it falls into the placement frame in the box body that is attracted by the magnetic suction frame.

[0018] (2) The replacement component provided in the present invention can replace the placement frame when the waste loaded in a placement frame reaches or exceeds 3 / 4. Each time the isolation component completes a working cycle, the distance measuring sensor provided on the magnetic suction frame will detect the stacking height of the waste in the placement frame. When the stacking height exceeds 3 / 4 of the internal height of the placement frame, the magnetic suction frame will cut off the power to the electromagnet, and the placement frame will slide downward in the box body to the buffer component. At the same time, the first telescopic rod connected to one side of the magnetic suction frame will be shortened, and the next empty placement frame will be pushed toward the magnetic suction frame through the push plate. At this time, the electromagnet provided at the bottom end of the magnetic suction frame will be energized again to re-attract the placement frame and the magnetic suction frame, and then the second telescopic rod provided in the partition plate will also be shortened, and the remaining placement frame group in the box body will be lifted up by the support plate until the bottom surface of the placement frame at the top is flush with the top surface of the partition plate.

[0019] (3) The buffer assembly provided in the present invention can buffer the falling placement frame to prevent the waste in the placement frame from falling into the cavity in the box body due to impact. When the placement frame falls onto the buffer frame, the buffer frame will move downward, causing the support arms at both ends to rotate and causing the slide bar to move downward along the fixed rod. At the same time, the elastic wheel and the second spring will buffer and absorb the impact, so that the placement frame will finally fall smoothly on the buffer frame.

[0034] The replacement component provided in the present invention can replace the placement frame 21 when the waste loaded in a placement frame 21 reaches or exceeds 3 / 4. Every time the isolation component completes a working cycle, the distance measuring sensor provided on the magnetic suction frame will detect the waste stacking height in the placement frame 21. When the stacking height exceeds 3 / 4 of the internal height of the placement frame 21, the magnetic suction frame will cut off the power to the electromagnet, and the placement frame 21 will slide downward in the box body 2 to the buffer component. At the same time, the first telescopic rod 20 connected to one side of the magnetic suction frame will be shortened, and the next empty placement frame 21 will be pushed toward the magnetic suction frame through the push plate 18. At this time, the electromagnet provided at the bottom end of the magnetic suction frame is re-energized to re-attract the placement frame 21 and the magnetic suction frame, and then the second telescopic rod 13 provided in the partition plate 24 will also be shortened, and the remaining placement frame 21 group in the box body 2 will be lifted up by the support plate 8 until the bottom surface of the placement frame 21 at the top is flush with the top surface of the partition plate 24.

[0035] like Figure 4 As shown, a first telescopic rod 20 is connected to one side of the magnetic bracket close to the first baffle 19 , a push plate 18 is provided at the free end of the first telescopic rod 20 , and the inner side of the push plate 18 contacts the outer side of a placement frame 21 .

[0036] like Figure 3 and Figure 4 As shown, a second telescopic rod 13 is arranged in the partition plate 24 , and an output end of the second telescopic rod 13 is connected to a support plate 8 , and the support plate 8 is slidably clamped in the box body 2 , and the top end of the support plate 8 contacts the bottom end of a placement frame 21 .

[0037] like Figure 3 and Figure 4 As shown, a buffer assembly is provided on the side of the partition plate 24 where the placement frame 21 is not placed, and the buffer assembly includes a buffer frame 9 that is slidably mounted in the box body 2, the buffer frame 9 is aligned with the magnetic frame in the vertical direction, and a pair of support arms 10 are hinged at both ends of the buffer frame 9, and the bottom ends of the two support arms 10 are rotatably connected to elastic wheels 12, and the outer sides of the elastic wheels 12 are in contact with the bottom wall of the box body 2, and a slide groove 11 is opened on the support arm 10, and a slide rod 16 is commonly penetrated in the slide grooves 11 of the two pairs of support arms 10.

[0038] like Figure 1 and Figure 3 As shown, a directional sleeve 15 is connected to the slide rod 16, a fixing rod 17 is arranged on the inner bottom wall of the box body 2, the directional sleeve 15 is passed through the fixing rod 17, the top end of the fixing rod 17 is connected to the buffer frame 9 through a second spring 14, a pressure sensor is arranged on the top end of the buffer frame 9, and a second baffle 3 is arranged on the outer wall of the box body 2 close to the buffer frame 9.

[0039] The buffer assembly provided in the present invention can buffer the falling placement frame 21 to prevent the waste in the placement frame 21 from falling into the cavity in the box body 2 due to impact. When the placement frame 21 falls onto the buffer frame 9, the buffer frame 9 will move downward, so that the support arms 10 at both ends of the frame rotate and the slide bar 16 moves downward along the fixed rod 17. At the same time, the elastic wheel 12 and the second spring 14 will buffer and absorb the impact, and finally the placement frame 21 will fall smoothly on the buffer frame 9.

[0040] like Figure 1 and Figure 6 As shown, a slanted plate is connected to one side of the magnetic bracket close to the second partition plate 29 , and the bottom end of the slanted plate is flush with one side of the sliding cover arranged at the top end of the placement frame 21 .

[0041] like Figure 6 As shown, a sealing assembly is provided on the outside of the box body 2, and the sealing assembly includes a control chamber 36 connected to the outside of the box body 2, and a motor 35 is provided in the control chamber 36. The output shaft end of the motor 35 is connected to a lead screw 31, and a first pneumatic rod 32 is passed through the lead screw 31. The first pneumatic rod 32 is perpendicular to the axis of the lead screw 31, and the output end of the first pneumatic rod 32 is connected to a second pneumatic rod 33. The bottom end of the second pneumatic rod 33 is connected to a suction cup 34, and the bottom end of the suction cup 34 is sucked into the upper surface of the sliding cover.

[0042] The sealing component in the present invention can seal the placement frame 21 that falls onto the buffer component. When using placement frames 21 of different sliding cover types, the working process of the motor 35, the first pneumatic rod 32 and the second pneumatic rod 33 is edited according to the movement path when the sliding cover is closed. For the sliding cover that slides back and forth, it is only necessary to edit the working order and stroke of the first pneumatic rod 32 and the second pneumatic rod 33. First, the first pneumatic rod 32 is extended to move the suction cup 34 set at the bottom end of the second pneumatic rod 33 to the top of the sliding cover, and then the second pneumatic rod 33 is driven downward to make the suction cup 34 sucked to the top of the sliding cover, and then the first pneumatic rod 32 is shortened until the sliding cover is closed. At this time, the suction cup 34 is released and the first pneumatic rod 32 and the second pneumatic rod 33 are reset.

[0043] The specific usage and function of this embodiment are as follows:

[0044] The isolation component provided in the present invention can prevent the transmission of pathogens caused by long-term exposure of hard sharp waste to the air. At the same time, there is no need for medical staff to manually operate the device when placing hard sharp waste into the device. When hard sharp waste needs to be discarded, the waste is directly placed into the box body 2 through the placement port 1. The waste will move along the guide slope 4 to the conveyor belt 6 covered on the rotating rod 5. The rotating rod 5 is driven to rotate to make the conveyor belt 6 move down with the waste. The waste will move to the material guide plate 28 under the movement of the material plate 25. After the waste is placed, the air pump 40 connected to the second air guide pipe 39 is started. The air pump 40 will draw the gas in the second air bag into the airtight cavity. At this time, the placement port 1 is opened. The first partition 7 clamped on one side of the 1 will gradually close the placement port 1. When the placement port 1 is completely closed, the second airbag is completely emptied, and the trigger button 38 connected to its free end will synchronously contact the switch 41 on the outside of the other air pump 40. At this time, the other air pump 40 will extract the gas in the air guide cavity 27 to inflate the first airbag 37. Therefore, the pneumatic rod 30 slidably clamped in the air guide cavity 27 will slide along one end of the material guide plate 28 together with the second partition 29, so that the waste on the material guide plate 28 is transferred to the second partition 29 and continues to fall under the action of gravity, slides into the opening on the side of the sliding cover through the inclined plate clamped on one side of the magnetic suction frame, and finally falls into the placement frame 21 sucked at the bottom end of the magnetic suction frame;

[0045] When the first airbag 37 is full, the air pump 40 connected to the first airbag 37 will start to extract the gas in the air guide cavity 27 after a certain delay, so that the second partition 29 is reset. When the second partition 29 is completely reset, similarly, the trigger button 38 set at the free end of the first airbag 37 contacts the switch 41 on the outside of the air pump 40 to control the air pump 40 to inflate the second airbag. When the second airbag is full, a working cycle is completed, and the device returns to its initial state. At this time, all the waste enters the placement frame 21, and the second partition 29 also closes the space where it is located, thereby realizing the unified storage and separate isolation of hard and sharp waste.

[0046] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
