Medical waste refers to medical institutions in the medical, preventive, health
care and other related activities generated by direct or indirect infectious, toxic and
other hazardous waste, including infectious, pathological, injurious, pharmaceutical,
chemical waste. These wastes contain a large number of bacterial viruses, and have
certain characteristics of space pollution, acute viral infection and latent infection,
such as not strengthening the management, discarded at will, allowed to mix into the
domestic waste, scattered to the people's living environment, will pollute the
atmosphere, water, land, animals and plants, causing the spread of disease. This can
seriously endanger people's physical and mental health. In today's environment
protection awareness is gradually increasing, it is the responsibility and duty of every
citizen to protect the environment. There are various technologies available today for
the disposal of medical waste, among which high-temperature incineration can fully
guarantee the environmental requirements of stabilization, safety, reduction and
harmlessness of medical waste, while meeting the contemporary development trend of
medical waste disposal.

that the garbage can be more flexible and convenient in use.
On the other side of the outer wall of the outer barrel 1, there is a foot pedal 4, and
one end of the foot pedal 4 is fixedly connected to the first link 401, and the other end of
the first link 401 is connected to the second link 402 through a pivot, and the top of the
second link 402 is connected to the push wheel 403. By pressing the foot pedal 4, the
first link 401 at one end of the foot pedal 4 can exert an upward thrust on the second link
402 using the lever principle, so that the top cover 101 can be lifted automatically by
the push wheel 403.
The side wall of the No. 2 rod 402 is integrally formed with a gear strip 5, and the
gear strip 5 is movably connected with No. 1 gear 501 on one side, and the No. 1 gear
501 is movably occluded with No. 2 gear 502 on one side, and the No. 2 gear 502 is
movably occluded with an arc-shaped rack 503 on one side, and the arc-shaped rack
503 is fixedly welded to one end of the movable cover 104, and when the No. 2 rod 402
rises, the gear strip 5 can drive the No. 1 gear 501 and the No. 2 gear 502 to rotate
simultaneously, thus, the curved rack 503 can be synchronously driven to rotate, so that
the movable cover 104 can be automatically controlled to lift off, so that the user can
throw the medical waste into the garbage can. After the foot pedal 4 is released, the upper cover 101 drops under the action of the counterweight block 102, and synchronously drives the movable cover 104 to drop, so that the garbage can is closed, so that the garbage can is still kept in a negative pressure state.
It should be noted that an anti-virus infectious medical waste bin with negative
pressure function can store medical waste through the inner barrel 103 and seal the top
of the outer barrel 1 through the upper cover 101, and seal the inner barrel 103 through
the movable cover 104, which will effectively reduce the outflow of germs, and the
upper cover 101 and the lower surface of movable cover 104 can be snapped to the
outer barrel 1 and the top of the inner barrel 103 through the recess 2. And through the
seal ring 201 to connect the seam for sealing, will further enhance the sealing effect of
the garbage can, through the negative pressure generator 3 can be the outer barrel 1
cavity of air extraction, so that the outer barrel 1 in the formation of negative pressure
state, can keep the pressure inside the barrel is always lower than the pressure of the
outside atmosphere, so that the discarded garbage tightly adsorbed in the barrel inside
the side wall, and the internal air will not flow out through the seam, effective prevent
the diffusion of aerosols and viruses, the use is safer, and the extracted air is discharged
into the filter tank 302, which is stored with medical alcohol, thus can kill the germs,
the safety of use will be further enhanced, the lithium battery 304 can be charged
through the charging port 303, and the negative pressure generator 3 can be powered by
the lithium battery 304, which makes the trash can more flexible and convenient in use,
and by stepping on the foot pedal 4, the first link 401 at one end of the foot pedal 4 can
exert upward thrust on the second link 402 using the lever principle, so that it can push the wheel 403 to lift the top cover 101 automatically. When the No.2 linkage 402 rises, it can synchronously drive the No.1 gear 501 and No.2 gear 502 to rotate through the gear bar 5, so that it can synchronously drive the curved rack 503 to rotate, thus, the movable cover 104 can be automatically controlled to lift, so that the user can throw the medical waste into the garbage can. After the foot pedal 4 is released, the upper cover
101 drops under the action of the counterweight block 102 and simultaneously drives
the movable cover 104 to drop, thus closing the garbage can, so that the garbage can is
still kept in a negative pressure state.
The negative pressure generator 3 of CV-20HS type adopts the existing mature
technology products, so we will not make detailed elaboration here.
Although embodiments of the present invention have been shown and described, it
will be understood by those of ordinary skill in the art that a variety of variations,
modifications, replacements and variants of these embodiments can be made without
departing from the principles and spirit of the present invention, the scope of which is
limited by the appended claims and their equivalents.
