It should be noted that the driving box 43 may be a rectangular parallelepiped, and may also be a cylinder, and the corresponding first, second, third, and fourth cylinders need not be located at four sides of the rectangular parallelepiped, and as long as the driving box is a hollow container and can accommodate the driving rod 41 to slide and rotate therein, it can be regarded as a homogeneous implementation manner; in addition, in order to make the driving rod 41 push the pressing plate 322, the pulling portion 413 automatically return to the initial position, a convex curve track 4311 may be provided in the top wall 431, and a curve groove 4111 may be correspondingly provided at the upper end of the rod 411 of the driving rod 41, so that when the pulling portion 413 and the driving head 412 are upward pushed, the convex curve track 4311 guides the groove 4111 of the rod 411, so that the driving head 412 automatically deflects in one direction in the first transverse groove 4371 to return to the initial position.

The specific operation method comprises the following steps:

the driving head 412 and the pulling part 413 of the driving rod 41 are first located in the first transverse groove 4371 and face the second vertical groove 4362, a user holds the pulling part 413 with one hand to pull the driving rod 41 to slide downwards in the second vertical groove 4362, at this time, the first elastic element 42 stores energy, the transmission foot 531 is pushed downwards by the driving head 412 to drive the transmission strip 53 to move downwards and sequentially transmit the energy to the second gear 52, the first gear 51 and the first rotating shaft 111, so that the first baffle 11 is turned over and opened, then the user puts the waste into the upper accommodating chamber 1 with the other hand, and at this time, the waste is placed on the partition plate 21. After the driving head 412 and the pulling part 413 of the driving rod 41 reach the second transverse slot 4362, the user holds the pulling part 413 to rotate the driving head 412 to the direction of the first vertical slot 4361, at this time, the first baffle 11 is closed, and then the user releases the pulling part 413, so that the driving rod 41 is pushed by the charged first elastic member 42 to move upwards. The driving head 412 first impacts the driving block 212, so that the driving block 212 drives the second rotating shaft 211 to rotate clockwise, and drives the partition 21 to turn over downwards, so that the waste falls into the lower accommodating chamber 2. The waste is more easily dropped due to the larger initial kinetic energy. The driving head 412 continues to move upward, and after leaving the driving block 212, both the driving block 212 and the diaphragm 21 return to the original positions due to the tendency of the second elastic member 213 to push the diaphragm 21 to return to the horizontal position. At this time, the rod 411 continues to move, and the upper end of the rod impacts the upper pressing plate 322, so that the rod moves towards the inside of the disinfectant spraying chamber 3, and the disinfectant spraying chamber 3 sprays disinfectant into the accommodating chamber 1. When the driving rod 41 leaves the pressing plate 322 next time, the pressing plate 322 is restored to the initial position under the urging of the spring 323, and at this time, the check valve 33 replenishes air into the disinfectant spraying chamber 3, so that the air pressure in the disinfectant spraying chamber 3 and the air pressure in the upper receiving chamber 1 are kept consistent, and the next spraying operation is waited. In order to take out medical waste conveniently, a movable and removable collecting container 6 is arranged in the lower accommodating chamber 2, and a handle 67 is arranged on the side wall of the collecting container 6 so as to be convenient for a user to push and pull. An insertion opening 141 with the same height as the collecting container is formed at the position of the lower accommodating chamber 2 at the lower part of the second side wall 123, a second baffle 23 capable of being opened inwards is hinged to the upper edge of the insertion opening, and the collecting container 6 can jack the second baffle 23 to enter the lower accommodating chamber 2.

The movable end of the top cover 61 is provided with a lock catch 64 which has the deformation capability, when the top cover 61 falls down, the lock catch 64 can lock the top cover 61 in a lock groove 65 on the inner surface of the box body 62; when the lock catch 64 is deformed, the lock catch can be separated from the lock groove 65, so that the top cover 61 is turned away from the box body 62; the locking groove 65 is opened with a through hole 66 penetrating the box body, and the third side wall 124 is provided with a protruding unlocking lever 22 at a position facing the through hole 66 in the lower accommodating chamber 2, so that the locking catch 64 can be pushed open through the through hole 66, and the top cover 61 of the collecting container 6 can be turned to leave the box body 62.

The specific operation method comprises the following steps: the user introduces the collection container 6 into the lower receiving chamber 2 through the insertion opening 141 while the second shutter 23 is opened inward. When the unlocking rod 22 penetrates through the through hole 66 to eject the lock catch 64, the top cover 61 is turned over and opened, so that the second baffle plate 23 is continuously turned upwards to an angle vertical to the horizontal plane, and waste can be thrown into the collection container. When the collecting container needs to be taken out, the user pulls the handle 67 to pull out the collecting container 6, at this time, because the height of the insertion opening 141 is the same as that of the collecting container 6, the top cover 61 gradually falls under the limiting action of the upper edge of the insertion opening 141, and finally reaches the closing position, at this time, the lock catch 64 is buckled into the lock groove 65, and the collecting container 6 is closed.
