Description

Technical Field

[0001] The present invention belongs to the technical field of medical waste recycling, and particularly relates to a self-aspirating trash can. Background Art

[0002] In the modern medical environment, with the continuous progress of diagnostic technologies, non-invasive and convenient diagnostic methods such as vaginal ultrasound (ultrasonic examination of vagina) have been widely used. During these examinations, disposable medical wastes such as plastic sheets used by patients are often difficult to accurately throw into the trash can due to their light material properties when being discarded. These wastes often cling to the lid of the trash can or even scatter on the ground, which not only affects the cleanliness and beauty of the medical environment, but also increases the risk of cross-infection, bringing unnecessary health hazards to medical staff and patients.

[0003] The patent with the publication number of CN220375454U discloses an automatic suction medical waste trash can, including: a trash can body, an opening cover assembly and a pressing cover; when in use, at the first use, step on the anti-slip pad to drive the top cover to rotate and open, put the garbage bag into the upper cavity inside the trash can body, then the garbage bag extends out from the edge of the trash can body, put the pressing cover on the upper end of the trash can body to press the edge of the garbage bag, install the suction pipeline and connect it with the corrugated airbag, and then only need to step on the anti-slip pad to open the top cover for garbage disposal. The corrugated airbag drives the suction holes on the suction pipeline to absorb waste gas, and the waste gas absorbed into the corrugated airbag is discharged from the air outlet pipe when the top cover is closed and drives the corrugated airbag to contract.

[0004] The above technical solution only reduces the infection risk of medical staff and patients by how to install or replace the garbage bag. However, the above technical solution cannot solve the technical problem that during the use of the trash can, due to the light quality of disposable medical wastes such as plastic sheets, it is often difficult to accurately throw them into the trash can when being discarded. Therefore, there is an urgent need to design a self-aspirating trash can that can adsorb wastes such as plastic sheets used by patients, effectively prevent them from scattering on the ground or clinging to the lid of the trash can, thereby maintaining the cleanliness and hygiene of the medical environment and reducing the risk of cross-infection. Summary of the Invention

[0005] The object of the present invention is to overcome the problem that the existing trash can cannot solve the problem that during the use of the trash can, due to the light quality of disposable medical wastes such as plastic sheets, it is often difficult to accurately throw them into the trash can when being discarded.

[0006] To achieve the above object, the technical concept adopted by the present invention is as follows: Provide a self-priming trash can, including a trash can body and a self-priming pressing mechanism provided on the trash can body; after opening the trash can lid, the medical waste is sucked into the trash can body through the self-priming component in the self-priming pressing mechanism, preventing medical waste, especially disposable medical waste such as plastic sheets, from being scattered on the ground outside the trash can. At the same time, the pressing wire component in the self-priming pressing mechanism can guide the throwing direction of the trash thrown into the trash can body, preventing the medical waste from adhering to the inner wall of the trash can body, so as to accurately throw the medical waste, especially disposable medical waste such as plastic sheets, into the trash can while making the medical waste settle to the inner bottom surface of the trash can body.

[0007] Based on the above technical concept, the technical solution adopted by the present invention is as follows: A self-priming trash can, including a trash can body and a trash can lid, further includes: A flip mechanism, including an electric push rod provided on the outer surface of the trash can body and a triangular flip piece provided on the trash can lid; the triangular flip piece is connected to the electric push rod; A self-priming pressing mechanism, which is respectively connected to the trash can body and the electric push rod.

[0008] In the above technical solution, preferably, the self-priming pressing mechanism includes a self-priming component provided inside the inner wall of the trash can body for adsorbing trash, and a pressing and guiding component provided inside the trash can body for guiding and pressing the trash.

[0009] For further limitation of the above technical solution, the self-priming component is arranged in a rectangular accommodating cavity inside the inner wall of the trash can body, and includes: A limiting plate, connected to the trash can body; A telescopic frame, one end passes through the inner wall of the trash can body and is connected to the side surface of the push rod part of the electric push rod, and the other end abuts against the limiting plate; A counterweight block, arranged on the telescopic frame; An upper airbag, located above the counterweight block and connected to the upper surface of the counterweight block; the upper airbag is provided with a vent hole, and the vent hole of the upper airbag is communicated with the vent hole located on the inner wall of the trash can body.

[0010] For further limitation of the above technical solution, the telescopic frame includes: A fixed part, connected to the side surface of the electric push rod after passing through the trash can body; A telescopic part, connected to the fixed part through a spring.

[0011] For further limitation of the above technical solution, the pressing and guiding component includes: A lower airbag, located below the counterweight block and connected to the lower surface of the counterweight block; Two pressing plates, the air vents of each pressing plate are connected to the air outlets of the lower airbag, and the bottom ends of the two pressing plates are respectively rotatably connected to the opposite inner walls of the trash can body.

[0012] Further limiting the above technical solution, a plurality of ventilation channels are provided inside each pressing plate, and each ventilation channel is communicated with the air outlet of the lower airbag.

[0013] Further limiting the above technical solution, the upper end of each pressing plate is connected to the movable end of the trash can lid through a connecting rope.

[0014] Further limiting the above technical solution, a strip-shaped through hole for facilitating the movement of the electric push rod is provided on the triangular flip piece.

[0015] Further limiting the above technical solution, a groove is provided at one end of the electric push rod connected to the triangular flip piece, and a connecting rod slidably connected to the strip-shaped through hole is provided in the groove.

[0016] Further limiting the above technical solution, an infrared sensor for sensing the approach of a human body is provided on the trash can body. Beneficial effects:

[0017] First, through the combined design of the infrared sensor, the flip cover mechanism, the self-suction component and the pressing and guiding component of the present invention, after the infrared sensor senses the approach of medical staff or patient family members to the trash can body, the flip cover mechanism is activated. While the flip cover mechanism opens the trash can lid, it drives the telescopic frame in the self-suction component to move synchronously. When the telescopic frame moves upward along the chamfer of the limiting plate to the upper end of the chamfer of the limiting plate, the upper airbag is compressed and deflated, and the lower airbag is stretched and inhales air. Until the telescopic frame completely leaves the chamfer of the limiting plate, the counterweight block falls freely after detaching from the telescopic frame. At this time, the flip cover mechanism drives the trash can lid to flip up and open completely, and the upper airbag is stretched and inhales air, so as to suck medical waste, especially disposable medical waste such as plastic sheets, into the trash can body, preventing the medical waste from scattering outside the trash can body. At the same time, the lower airbag is compressed and deflated, and then the pressing plate communicated with the lower airbag plays a guiding role in the movement direction of the medical waste, preventing the medical waste, especially disposable medical waste such as plastic sheets, from adsorbing on the inner wall of the trash can body, so as to realize that while the medical waste is sucked into the trash can body, the medical waste sinks to the inner bottom of the trash can body.

[0018] Second, through the combined design of the pressing plate, the connecting rope and the trash can lid of the present invention, during the process of closing the trash can lid after the medical waste is put in, the pressing plate no longer receives the pulling force of the connecting rope, so the pressing plate flips down synchronously with the trash can lid to press the medical waste located in the trash can body, thereby reducing the volume and looseness of the garbage, improving the accommodation capacity of the trash can and the efficiency of garbage disposal.

[0019] III. Through the combined design of the triangular flip piece and the electric push rod, the present invention can achieve the flipping operation of the trash can lid without a complex structure, and the manufacturing cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] The embodiments of the present invention are applicable to the throwing of medical waste, and are particularly applicable to the throwing of disposable medical waste such as plastic sheets in the scenario of vaginal ultrasound examination.

[0029] Embodiment 1 This embodiment provides a self - suction trash can, as Figure 1-17 shown, including a flip - cover mechanism 1, a self - suction mechanism 2, a trash - can body 3, and a trash - can lid 4.

[0030] Among them, as Figure 1 shown, the trash - can body 3 is rotatably connected to the trash - can lid 4 through a rotating connecting piece, and the trash - can body 3 is connected to the flip - cover mechanism 1.

[0031] The flip - cover mechanism 1 includes an electric push rod 11 arranged on the outer surface of the trash - can body 3 and a triangular flip - piece 12 arranged on the trash - can lid 4; the triangular flip - piece 12 is connected to the output end of the electric push rod 11.

[0032] As Figure 1 and 8 shown, the electric push rod 11 is vertically arranged on the rear surface of the trash - can body 3; specifically, a U - shaped groove is provided at the free end of the push - rod part of the electric push rod 11, and a horizontally arranged connecting rod 11a is arranged in the U - shaped groove; a strip - shaped through - hole 12a is provided on the triangular flip - piece 12, and the strip - shaped through - hole 12a is used for connecting with the connecting rod 11a.

[0033] During actual use, the connecting rod 11a can slide in the strip - shaped through - hole 12a. Specifically, when the trash - can lid 4 is in the closed state, that is, when the trash - can lid 4 is in a horizontal state, as Figure 13 shown, the electric push rod 11 is at the end of the strip - shaped through - hole 12a far from the trash - can body 3; when the trash - can lid 4 is in the open state, that is, when the trash - can lid 4 is in a vertical state, as Figure 6 shown, the electric push rod 11 is at the end of the strip - shaped through - hole 12a close to the trash - can body 3.

[0034] During use, after the connecting rod 11a passes through the strip - shaped through - hole 12a, its two ends are respectively connected to the inner walls of the U - shaped groove. In this way, when the electric push rod 11 extends upward, the connecting rod 11a slides upward inside the strip - shaped through - hole 12a while moving upward. At this time, the electric push rod 11 drives the triangular flip - piece 12 to rotate through the connecting rod 11a, and further enables the trash - can lid 4 connected to the triangular rotating piece 12 to rotate synchronously, realizing the flipping of the trash - can lid 4, that is, realizing the switching of the trash - can lid 4 from the closed state to the open state.

[0035] In order to be able to open the trash - can lid 4 in time and avoid direct contact between medical staff, patient families and other personnel with the trash - can lid 4, as Figure 1 and 9As shown in the figure, an infrared sensor 5 is provided on the trash can body 3, and the infrared sensor 5 is telecommunicationally connected to the electric push rod 11. In this way, after the electric push rod 11 receives the signal sent by the infrared sensor 5, it is turned on, so that the push rod part of the electric push rod 11 extends out. The connecting rod 11a drives the trash can lid 4 to flip through the triangular rotating piece 12, so that the trash can lid 4 is opened.

[0036] After the garbage is put in, the infrared sensor 5 no longer senses the approach of the human body, and the electric push rod 11 is closed, so that the push rod part of the electric push rod 11 retracts downward, and then drives the connecting rod 11a to slide downward in the strip-shaped through hole 12a, so that the connecting rod 11a pulls the trash can lid 4 downward through the triangular rotating piece 12, so as to close the self-priming trash can.

[0037] It should be noted that the telecommunication connection method between the infrared sensor 5 and the electric push rod 11 provided in the embodiment of the present invention is the prior art, and the embodiment of the present invention does not improve this.

[0038] Inside the rear inner wall of the trash can body 3, there is a rectangular accommodating cavity for installing the self-priming pressing mechanism 2. Among them, an opening facilitating the movement of the self-priming pressing mechanism 2 is provided on the rear inner wall of the trash can body 3, and the opening communicates with the rectangular accommodating cavity.

[0039] The self-priming pressing mechanism 2 includes a self-priming component provided inside the inner wall of the trash can body 3 for adsorbing garbage, and a pressing and guiding component provided inside the trash can body 3 for guiding and pressing the garbage.

[0040] As Figure 3 and 4 shown, the self-priming component includes a limiting plate 21, a telescopic frame 22, a counterweight 23 and an upper airbag 24. Among them, the upper airbag 24 is located above the counterweight 23; The upper airbag 24 is fixedly connected to the upper surface of the counterweight 23, and the air outlet of the upper airbag 24 communicates with the air vent provided on the inner wall of the trash can body 3. It should be noted that the embodiment of the present invention does not limit the fixed connection method between the counterweight 23 and the upper airbag 24. For example, the fixed connection method between the counterweight 23 and the upper airbag 24 is adhesive bonding.

[0041] In practical applications, in order to prevent dust, paper scraps and other impurities from entering the upper airbag 24, a filter screen is also provided at the connection between the upper airbag 24 and the air vent provided on the inner wall of the trash can body 3.

[0042] Among them, a limiting plate 21 is respectively provided on both sides inside the rectangular accommodating cavity of the trash can body 3, and the limiting plate 21 is fixedly arranged on the inner wall of the rectangular accommodating cavity of the trash can body 3. Specifically, as Figure 3 and 4As shown, the limiting plate 21 is a vertically arranged square structure, and the lower end corners of the limiting plate 21 are chamfered.

[0043] As Figure 15-17 shown, the telescopic frame 22 includes a fixed part 22a, a telescopic part 22b, a spring 22c, and a limiting rod 22d.

[0044] The fixed part 22a is a rectangular structure, and there are three identical square openings on the surface of the fixed part 22a close to the trash can body 3; among them, the side of the fixed part 22a away from the trash can body 3 is fixedly connected to the side surface of the push rod part of the electric push rod 11.

[0045] In practical applications, a spring 22c is provided in each square opening. One end of the spring 22c is fixedly connected to the inner wall of the square opening of the fixed part 22a, and the other end is fixedly connected to the end of the telescopic part 22b.

[0046] Specifically, a telescopic part 22b is slidably arranged in each square opening, and one end of each telescopic part 22b is fixedly connected to the spring 22c, and the other end is in contact with the counterweight 23. In actual use, the movable ends of the telescopic parts 22b at both ends of the fixed part 22a are respectively abutted against the chamfered inclined surfaces of the limiting plate 21, and the telescopic part 22b in the middle expands and contracts as the telescopic parts 22b on both sides of it expand and contract, or expands as the telescopic parts 22b on both sides of it extend.

[0047] The limiting rod 22d is horizontally arranged with the fixed part 22a, and the limiting rod 22d is fixedly connected to one end of each telescopic part 22b away from the spring 22c. Among them, the limiting rod 22d is used to hang the counterweight 23.

[0048] The counterweight 23 is a C-shaped structure. The groove of the counterweight 23 is in contact with the limiting rod 22d, so that the counterweight 23 is hung on the limiting rod 22d, and the counterweight 23 is located between the two limiting plates 21; during use, the counterweight 23 is squeezed between the inner wall of the square accommodating cavity of the trash can body 3 and the limiting rod 22d under the action of the spring 22c and the limiting rod 22d; Among them, a limiting block is respectively provided below both ends of the counterweight 23, and the limiting block is fixedly arranged on the inner wall of the square accommodating cavity of the trash can body 3; In the initial state, the counterweight 23 is located above the limit block and is in contact with the upper surface of the limit block; while the telescopic part 22b moves upward, the limit rod 22d and the counterweight suspended on the limit rod 22d move upward synchronously. When the telescopic part 22b moves upward until it leaves the chamfered slope of the limit plate 21, the limit rod 22d no longer contacts the counterweight 23, causing the counterweight 23 to fall freely; during the free fall of the counterweight 23, the upper airbag 24 is continuously stretched, so the upper airbag 24 continuously inhales air. Since the upper airbag 24 is communicated with the air vent provided on the inner wall of the trash can body 3, the upper airbag 24 inhales the gas in the trash can body 3 into it until the counterweight 23 returns to the initial position, that is, the counterweight 23 is in contact with the upper surface of the limit block; when the telescopic part 22b moves downward, the limit rod 22d connected to the telescopic part 22b abuts against the side surface of the upper airbag 24. Until the limit rod 22d leaves the side surface of the upper airbag 24 and contacts the groove of the counterweight 23, at this time, the spring 22c is no longer squeezed by the side surface of the upper airbag 24, and the spring 22 returns to its natural state, causing the telescopic part 22b to extend out of the square opening of the fixed part 22a, and further causing the limit rod 22d to be located in the groove of the counterweight 23, realizing the suspension of the counterweight 23.

[0049] The upper airbag 24 is of a square structure, and the air vent of the upper airbag 24 is communicated with the air permeable port provided on the inner wall of the trash can body 3. Specifically, the upper airbag 24 is located in the square accommodating cavity on the inner wall of the trash can body 3, and the front wall and the rear wall of the upper airbag 24 are squeezed by the inner wall of the square accommodating cavity. During the process that the counterweight 23 moves upward under the action of the limit rod 22d and squeezes the upper airbag 24, the upper airbag 24 deforms in the vertical direction.

[0050] During actual use, in order to prevent the counterweight 23 from falling to the bottom of the accommodating cavity of the trash can body 3, a limit block is further provided at the bottom of the square accommodating cavity of the trash can body 3 below the limit plate 21, and the limit block is used to limit the falling height of the counterweight 23.

[0051] The working principle of the self - suction component provided by the embodiment of the present invention is as follows: The electric push rod 11 extends upward. While driving the trash can lid 4 to flip through the connecting rod 11a, the push rod part of the electric push rod 11 drives the telescopic frame 22 to move upward synchronously. While the telescopic part 22b moves upward, the telescopic part 22b moves into the square opening of the fixed part 22a, driving the limit rod 22d to move upward along the chamfered slope of the limit plate 21; Specifically, when the limiting rod 22d moves upward along the chamfered inclined surface of the limiting plate 21, the telescopic parts 22b at both ends of the telescopic frame 22 move into the corresponding square openings under the limiting action of the chamfered inclined surface of the limiting plate 21. Furthermore, the telescopic parts 22b on both sides of the telescopic frame 22 drive the telescopic part 22b in the middle square opening to move into the corresponding square opening through the limiting rod 22d. At this time, the springs 22c in each square opening are compressed; Furthermore, when the limiting rod 22d reaches the upper end of the chamfered inclined surface of the limiting plate 21, the trash can lid 4 is fully opened so that medical staff can put medical waste into the trash can body 3. Specifically, after the counterweight 23 loses the support of the limiting rod 22d, it falls freely. During the free fall of the counterweight 23, the upper airbag 24 is continuously stretched by the counterweight 23. The upper airbag 24 continuously sucks the gas in the trash can body 3 into its interior, causing an air flow in the trash can body 3 to suck medical waste, especially disposable medical waste such as plastic sheets, into the trash can body 3. The counterweight 23 falls freely until it contacts the upper surface of the limiting block below it, making the counterweight 23 in its initial position to prevent the counterweight 23 from continuing to fall; While the upper airbag 24 is continuously stretched by the free fall of the counterweight 23, the limiting rod 22d contacts the side surface of the upper airbag 24.

[0052] To facilitate the limiting rod 22d to leave the groove of the counterweight 23, lubricating oil can be applied to the limiting rod 22d. In actual application, lubricating oil can be added through the opening communicating with the square accommodating cavity of the trash can body 3 to reduce the friction between the limiting rod 22d and the counterweight 23.

[0053] During actual use, after the infrared sensor 5 senses that the human body has left, the electric push rod 11 retracts. At this time, the electric push rod 11 drives the trash can lid 4 to flip in the opposite direction. While closing the trash can lid 4, the electric push rod 11 drives the limiting rod 22d to move downward synchronously through the telescopic part 22b until the limiting rod 22d no longer contacts the side surface of the upper airbag 24. The spring 22c returns to its natural state, causing the limiting rod 22d to enter the groove of the counterweight 23 and contact the counterweight 23. At this time, the counterweight 23 is suspended on the limiting rod 22d, and the upper airbag 23 returns to its natural state for the next medical waste disposal.

[0054] The pressing guide assembly includes a lower airbag 25, two pressing plates 26 and two connecting ropes 27; Among them, the lower airbag 25 is arranged in the square accommodating cavity inside the inner wall of the trash can body 3 and is fixedly connected to the lower surface of the counterweight 23; The two pressing plates 26 and the two connecting ropes 27 are both located inside the trash can body 3.

[0055] A rotating rod is provided at the bottom of each pressing plate 26, and both ends of the rotating rod are rotatably connected to the trash can body 3; one end of each connecting rope 27 is fixedly connected to the upper end of the corresponding pressing plate 26, and the other end is fixedly connected to the movable end of the trash can lid 4.

[0056] Two symmetrically arranged air outlets are provided at the bottom of the lower airbag 25. After the two air outlets penetrate through the rectangular accommodating cavity of the trash can body 3 respectively, they are respectively communicated with the ventilation channels in the corresponding pressing plates 26. Specifically, the air outlet of the lower airbag 25 is connected to the air inlet of the corresponding pressing plate 26, and the air inlet of the pressing plate 26 is communicated with each of its own ventilation channels.

[0057] In this way, during the process of the counterweight 23 freely falling and squeezing the lower airbag 25, the lower airbag 25 continuously discharges air. The gas in the lower airbag 25 flows out from the air outlet provided at the upper end of the pressing plate 26 into the interior of the trash can body 3 through the ventilation channels of the pressing plate 26. In this way, the two pressing plates 26 inside the trash can body 3 discharge air relatively, thereby guiding the movement direction of the medical waste, so that while the upper airbag 24 sucks the medical waste into the trash can body 3, it prevents the medical waste from adhering to the inner wall of the trash can body 3, and further enables the medical waste to settle to the inner bottom of the trash can body 3.

[0058] It should be noted that a limiting plate is further provided below the pressing plate 26, and the limiting plate is fixedly arranged on the inner wall of the trash can body 3 to limit the range of downward rotation of the pressing plate 26, so that in the scenario where the self-suction trash can is closed, the pressing plate 26 is in a horizontal state.

[0059] The working principle of the pressing and guiding assembly provided by the embodiment of the present invention is as follows: The electric push rod 11 moves upward to flip the trash can lid 4, so that while the self-suction trash can is opened, the trash can lid 4 drives the pressing plate 26 to flip upward through the connecting rope 37, so that the air outlets of the two pressing plates 26 inside the trash can body 3 are on the same horizontal plane; During the upward movement of the electric push rod 11, the electric push rod 11 drives the telescopic frame 22 to move upward synchronously. Until the limiting rod 22d leaves the chamfered slope of the limiting plate 21, the counterweight 23 loses the support force of the limiting rod 22d and freely falls. The counterweight 2 continuously squeezes the lower airbag 25, so that the lower airbag 25 continuously discharges air. The gas in the lower airbag 25 flows out from the air outlet of the lower airbag 25 and enters the ventilation channels of the pressing plate 26, and then the gas flows out from the air outlets of the ventilation channels and enters the interior of the trash can body 3, so that the two pressing plates 26 respectively provide a horizontal airflow inside the trash can body 3, and the airflow directions provided by the two pressing plates 26 are opposite, so as to realize the guiding of the movement direction of the medical waste; When the infrared sensor 5 no longer detects the approach of the right human body, it indicates that the waste has been put in. The push rod part of the electric push rod 11 retracts, driving the trash can lid 4 to flip downward. At this time, the electric push rod 1 drives the limit rod 22d to move downward through the telescopic part 22b until the limit rod 22d is located in the groove of the counterweight 23 for the next medical waste disposal. At the same time, the pressing plate 26 is no longer subjected to the pulling force of the connecting rope 27, so it flips downward to press the waste thrown into the trash can body 3, reducing the volume and looseness of the waste, improving the accommodation capacity of the trash can and the efficiency of waste treatment. During this process, the pressing plate 26 contacts the limit plate arranged below, making each pressing plate 26 in a horizontal state.

[0060] Implementation case: Step 1: After the infrared sensor 5 senses the approach of medical staff, patient families and other people to the trash can body 3, the electric push rod 11 is turned on to make the electric push rod 11 extend; During the upward extension of the electric push rod 11, the movable end of the electric push rod 11 moves upward in the strip-shaped through hole 12a to flip the trash can lid 4; while the trash can lid 4 flips, the trash can lid 4 drives the pressing plate 26 to flip upward through the connecting rope 27; At the same time, the limit rod 22d moves upward along the chamfered slope of the limit plate 21. At this time, the upper airbag 24 deflates and the lower airbag 25 inhales; when the limit rod 22d moves to the upper end of the chamfered slope of the limit plate 21, the limit rod 22d leaves the groove of the counterweight 23. After the counterweight 23 loses the support force of the limit rod 22d and freely falls, the trash can lid 4 is completely opened; Step 2: Medical staff or patient families throw medical waste, especially disposable medical waste such as plastic sheets, into the trash can body 3; In this step, when the counterweight 23 moves to the end of the chamfered slope of the limit plate 21, the limit rod 22d leaves the groove of the counterweight 23. At this time, after the counterweight 23 loses the support force of the limit rod 22d and freely falls, during the free fall of the counterweight 23, the upper airbag 24 is continuously stretched by the counterweight 23, and the upper airbag 24 continuously inhales to suck the medical waste into the trash can body 3. At this time, the limit rod 22d contacts the side surface of the upper airbag 24; At the same time, during the free fall of the counterweight 23, the lower airbag 25 is continuously squeezed by the counterweight 23 and deflates. The gas in the lower airbag 25 flows out from the air outlet of the pressing plate 26 through the ventilation channel of the pressing plate 26 to guide the movement direction of the medical waste inhaled into the trash can body 3, preventing the medical waste, especially disposable medical waste such as plastic sheets, from adhering to the inner wall of the trash can body and making the medical waste settle to the inner bottom of the trash can body 3; Step 3: After the infrared sensor 5 senses that the medical staff has left the trash can body 3, the electric push rod 11 retracts, driving the trash can lid 4 to rotate counterclockwise. At the same time, the electric push rod 11 drives the telescopic frame 22 back to the initial position. During this process, after the limit rod 22d leaves the side surface of the upper airbag 24, when the spring 22c returns to its natural state, the limit rod 22d moves towards the side of the counterweight 23 until the limit rod 22d contacts the side surface of the groove of the counterweight 23. At this time, the upper airbag 24 and the lower airbag 25 return to the initial state for the next disposal of medical waste.
