Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 9, a medical trash can includes a base 46, an outer can body 13, and an inner can body 14.

The base 46 is cylindrical, the lower part of the base 46 is fixedly connected with three first support legs 1 which are uniformly distributed along the circumferential direction, the first support legs 1 radially extend outwards along the base 46, and the tail end of each first support leg 1 is connected with a first universal wheel 2.

The outer barrel body 13 is fixedly arranged on the base 46, the electric box 3 is fixedly arranged on the outer wall of the outer barrel body 13, the top of the electric box 3 is flush with the upper end of the outer barrel body 13, the exhaust device 9 is fixedly arranged at the top of the electric box 3, the air supply device 8 is arranged on the side portion of the electric box 3, the air curtain extending along the horizontal direction is formed after the air flow generated by the air supply device 8 passes through the exhaust device 9 and blows towards the outer barrel body 13, and a battery used for supplying power to the air supply device 8 is arranged inside the electric box 3.

The inner barrel body 14 is detachably arranged in the outer barrel body 13, the upper end of the inner barrel body 14 is opened to form an opening 27, a semicircular fixed cover plate 26 is fixedly connected to the upper end of the inner barrel body 14, one half of the opening 27 is closed by the fixed cover plate 26, a semicircular movable cover plate 18 is rotatably connected to the fixed cover plate 26, and the movable cover plate 18 is used for opening or closing the other half of the opening 27.

In the present invention, the pedestal 46 and the outer tub 13 are reused, and the inner tub 14 is disposable.

When using, promote suitable position with the garbage bin according to actual need, first universal wheel 2 can conveniently remove the garbage bin this moment, and three first supporting leg 1 can promote the stability of garbage bin, and specifically speaking, no matter the point of application of force is between which two first supporting leg 1, another one first supporting leg 1 can both play the supporting role to avoid toppling over because of thrust is too big at the removal in-process. After reaching the proper position, an inner barrel body 14 is taken and put into the outer barrel body 13, and the movable cover plate 18 is turned over to open half of the opening 27, so that the medical waste can be put into the inner barrel body 13. Considering that the medical waste itself may emit peculiar smell or may generate the diffusion of harmful microorganisms such as bacteria, etc., the air supply device 8 is opened when the medical waste is not needed to be thrown in, the air supply device 8 generates air flow and sends the air flow into the air exhaust device 9, an air curtain along the horizontal direction is formed after passing through the air exhaust device 9 and blows towards the opening 27, the peculiar smell and the microorganisms generated by the medical waste are blocked in the inner barrel body 14 under the action of the air curtain and cannot be emitted outwards, and the cleanness of the surrounding environment is effectively ensured. When rubbish is needed to be thrown in again, the air supply device 8 is turned off for a short time, so that the air curtain is suspended, and peculiar smell and microorganism diffusion caused by blowing the air curtain on the medical rubbish can be effectively avoided. After the inner barrel body 14 is filled, the opening 27 is completely closed by turning over the movable cover plate 18, and the movable cover plate 18 is fixed, so that the medical waste can be sealed in the inner barrel body 14, and then the inner barrel body 14 is taken out to be further processed together with the inner barrel body 14 and the medical waste as a whole, thereby avoiding the medical waste from being polluted in the transferring process. Finally, a new inner barrel body 14 is taken for use.

In the invention, the base 46, the outer barrel body 13 and the inner barrel body 14 can be made of plastic materials, and particularly, the inner barrel body 14 can be made of hard plastic because the medical waste needs to be sealed for integral burning, so that the medical waste leakage caused by damage in the transportation process is avoided.

Because the electrical box 3 is fixed on the outer barrel body 13, the center of gravity of the whole garbage can is deviated, if the garbage can is collided from the opposite direction of the electrical box 3, the garbage can is easy to topple, a second supporting leg 6 extending outwards in the radial direction is fixedly connected on the base 46, the second supporting leg 6 is positioned below the electrical box 3, the distance between the second supporting leg 6 and two adjacent first supporting legs 1 is equal, and the tail end of the second supporting leg 6 is connected with a second universal wheel 7. The second supporting leg 6 can carry out auxiliary stay to the electric box 3 to stabilize the focus of garbage bin, avoid the garbage bin to empty.

In order to ensure that the air curtain can face the position of the opening 27, a limit pin 23 is vertically and fixedly arranged at the bottom of the inner wall of the outer barrel body 13, a limit sleeve 25 matched with the limit pin 23 is fixedly arranged at the bottom of the inner barrel body 14, the limit sleeve 25 extends towards the inside of the inner barrel body 14, namely the limit sleeve 25 is positioned inside the inner barrel body 14, the lower end of the limit sleeve 25 penetrates through the bottom of the inner barrel body 14, and the upper end of the limit sleeve 25 is closed. When the inner barrel body 14 is placed into the outer barrel body 13, the limiting sleeve 25 is aligned to the limiting pin 23, so that the inner barrel body 14 is limited, and the effectiveness of an air curtain is guaranteed.

In order to fix the movable cover plate 18 when the inner barrel body 14 is closed, an adhesive layer 16 is arranged on the arc edge of the movable cover plate 18, and the surface of the adhesive layer 16 is covered with a protective coating 15. After the inner tub 14 is filled, the protective film 15 is first peeled off to expose the adhesive layer 16, and then the flap 18 is rotated to bond the flap 18 and the outer tub 13 together via the adhesive layer 16.

Further, a notch 33 is formed in the middle of the adhesive layer 16, a locking device 17 is arranged in the notch 33, the locking device 17 comprises a connecting column 32 and a soft chuck 31 which are fixedly connected, the connecting column 32 is cylindrical and is fixedly connected with the movable cover plate 18, the soft chuck 31 is conical, the large end of the soft chuck 31 is coaxially and fixedly connected with the connecting column 32, and the diameter of the large end of the soft chuck 31 is larger than that of the connecting column 32. The through hole 29 and the containing cavity 28 which are mutually communicated are formed in the inner part of the barrel wall of the outer barrel body 13, the through hole 29 penetrates through the upper end of the outer barrel body 13, the through hole 29 is used for containing a connecting column 32, and the containing cavity 28 is used for containing a soft clamping head 31. When the opening 27 is completely closed by the removable cover 18, the soft clip 31 passes through the through hole 29 and enters the cavity 28, and since the soft clip 31 is conical, the soft clip 31 can be deformed by the through hole 29 pressing the conical surface of the soft clip 31 when passing through the through hole 29, so that the soft clip 31 can pass through the through hole 29 smoothly. If the soft chuck 31 is pulled out reversely after the soft chuck 31 enters the cavity 28, the through hole 29 will press the plane of the soft chuck 31, so that the soft chuck 31 is hard to deform, and the soft chuck 31 can be prevented from being pulled out from the cavity 28. Through setting up locking device 17, can further fix removable cover 18, avoid the in-process removable cover 18 of transportation to open and cause medical waste to scatter.
