Referring to fig. 1-7, the present invention provides a technical solution: the medical waste classification treatment device for the operating room comprises a motor 10 and a ring shell 11, wherein a plurality of spiral chutes 12 are formed in the ring shell 11, a plurality of vertical equidistant horizontal ring sleeves 13 are arranged in the spiral chutes 12 in a sliding manner through sliding rods, ring plates 14 are fixedly arranged at the upper ends of the horizontal ring sleeves 13, supporting springs 15 are fixedly arranged at the lower ends of the horizontal ring sleeves 13 and the upper ends of the ring plates 14, the supporting springs 15 are tightly attached to the inner wall of the ring shell 11, openings 16 are formed in the side walls of the ring shell 11 between the horizontal ring sleeves 13 and the ring plates 14, inclined sliding plates 17 used for placing waste are fixedly arranged on the outer walls of the ring shell 11 at the edges of the openings 16, the ring plates 14 at the uppermost ends are in threaded connection with a driving rod 30, the rest of the ring plates 14 are connected with the driving rod 30 in a sleeved manner, the upper ends of the driving rod 30 are coaxially and fixedly arranged on an output shaft of the motor 10, the motor 10 is fixedly arranged on the inner wall of the upper end of the ring shell 11 through a support, disinfection holes 18 are formed in the side walls of the driving rod 30 between the horizontal ring sleeves 13 and the ring plates 14, and spray nozzles 19 are fixedly arranged in the disinfection holes 18;

in order to solve the problem that the conventional medical trash can usually adopts a plurality of conventional trash cans or a single trash can with intervals, the size of the trash can is too large as a whole, and the space of an operating room is compressed; secondly, as a lot of garbage such as protective clothing is large in size, the garbage can is prone to occupy too large space after being thrown into a garbage can with a fixed size, so that the garbage can is wasted in space, the garbage can needs to be dumped for multiple times, and the operating room is likely to be compact in service time, so that a lot of manpower and time are wasted;

when the device is used, the device is assembled (as shown in fig. 1, the device adopts an annular design and a multi-layer folding design, wherein the upper end of the device is seen from top to bottom in fig. 1, the front end of the device is seen from one side of an inclined sliding plate 17 in the figure, and the direction of equipment is used for description and is not repeated);

when the device is used, the space between the ring plates 14 corresponding to each layer of inclined sliding plate 17 is a classification standard, namely each layer represents a corresponding garbage can for garbage classification (as shown in fig. 1 and 2, since the device has a compression function, classification grids with small compressibility are placed at the upper end as much as possible, so that the gravity of garbage at the upper end is concentrated to press the garbage at the lower end during compression, thereby achieving the effects of energy conservation and emission reduction), when the garbage needs to be thrown away, the garbage is thrown onto the inclined sliding plate 17, so that the garbage slides along the inclined sliding plate 17 to pass through the opening 16 on the side wall of the ring shell 11 to enter between the two corresponding ring plates 14 inside the ring shell 11 (as shown in fig. 2 and 4, wherein the stiffness coefficient of the supporting spring 15 is large, thereby the spiral interval of the supporting spring 15 is large, thereby preventing the supporting spring 15 from blocking at the side wall of the opening 16 and blocking the garbage from entering the garbage interval of the ring shell 11, thereby causing the problem that garbage cannot smoothly slide between the ring plates 14 inside the ring shell 11), when the garbage needs to be compressed after being thrown, the starting motor 10 rotates to drive the driving rod 30 to rotate, the driving rod 30 rotates to drive the ring plate 14 at the uppermost end to descend so as to drive the horizontal ring sleeve 13 to descend, because the side wall of the horizontal ring sleeve 13 is arranged inside the spiral chute 12 arranged on the side wall of the ring shell 11 in a sliding way through the sliding rod, and because the center of the ring plate 14 at the uppermost end is sleeved with the vertical hollow driving rod 30, the driving rod 30 is in threaded connection with the ring plate 14 at the uppermost end, the threaded connection interval is smaller than the spiral interval of the spiral chute 12, the horizontal ring sleeve 13 can smoothly spirally descend along the track of the spiral chute 12, thereby pressing the first layer (when the horizontal ring sleeve 13 at the upper end moves downwards, the ring plate 14 at the lower end is pressed through the supporting spring 15, although the supporting springs 15 will have a certain deformation, the ring plates 14 of each layer start to be compressed at the same time, and for convenience of understanding, the ring plates 14 of the lower layer are firstly kept static, and only the supporting springs 15 corresponding to the compressed layer are deformed; meanwhile, the supporting spring 15 is tightly attached to the inner wall of the annular shell 11, and plays a certain supporting role; although the supporting spring 15 is sleeved on the outer wall of the driving rod 30, the effect that the opening 16 cannot be shielded can be achieved, but the spray head 19 on the side wall of the driving rod 30 can be shielded to work, so that the disinfection work of the spray head 19 is interfered, and the applicability of the equipment is improved; further, the compression spiral of the supporting spring 15 is close to the center at intervals to play a role in shielding the opening 16, so that the problem that garbage is extruded from the opening 16 is solved, the horizontal ring sleeve 13 descends to enable the ring plate 14 at the upper end to rotate and descend, so that the problem that the acting force of the lower supporting spring 15 compresses the garbage at the lower layer is solved, the ring plate 14 rotates and presses downwards to enable the garbage at the lower layer to be twisted, and the garbage at the outermost side is extruded with the ring shell 11, so that the internal structure of the garbage is changed, the garbage can be pressed more tightly, the compression ratio is improved, the size of the compressed garbage is smaller, the later-stage transportation is facilitated, meanwhile, as shown in fig. 2 and 3, the horizontal ring sleeve 13 is fixedly arranged below the ring plate 14, the strength of the ring plate 14 is enhanced, the problem that the ring plate 14 is too heavy is avoided, the horizontal ring sleeve 13 with higher strength can preferentially press the garbage at the edge of the ring shell 11, the lower end of the ring plate 14 is in a suspended state, and the stress point of the ring plate 14 and the edge of the driving rod is avoided from being warped;

when the garbage on the uppermost layer is compressed to a state that the garbage is larger than the supporting springs 15 and cannot be compressed, the ring plate 14 at the bottom end of the upper layer and the ring plate 14 at the bottom end of the upper layer overcome the elastic force of the supporting springs 15 to press, rotate and descend to compress the second layer until the last layer is compressed, and all the compression is finished; when disinfection is needed, disinfectant is injected into the driving rod 30 after being pressurized, then the disinfectant enters the spray head 19 through the disinfection hole 18, the driving rod 30 continuously rotates along with the rotation of the pressed garbage, and the spray angle of the spray head 19 is changed, so that the disinfection is more thorough; when the garbage is required to be cleaned, when all the layers are compressed to the end, the garbage can be discharged out of the ring shell 11 only by detaching the ring plate 14 at the lowest end and continuously keeping the motor 10 rotating.

According to the invention, the driving rod 30 is driven to rotate by the motor 10, so that the ring plate 14 descends to drive the horizontal ring sleeve 13 to descend, and the horizontal ring sleeve 13 descends to rotate under the action of the spiral chute 12, so that the ring plate 14 rotates while descending, and the lower layer of garbage is rotationally pressed and pressed by overcoming the elasticity of the lower layer of supporting spring 15, so that the pressing is more uniform and thorough, the volume is smaller, the later transfer is facilitated, more garbage can be contained in one step until each layer of garbage is pressed completely, and therefore, the problem that the garbage can is stored in a fixed space of the existing garbage can, the space distribution is unreasonable, the garbage can is wasted due to the space resources, and the garbage can also needs to be poured for multiple times to cause the waste of human resources is solved; and the garbage can form of stacking reduces the occupied area of the garbage can, thereby causing the problem of space waste of an operating room.

In the invention, when garbage is pressed, the garbage can pass through the interval of the supporting spring 15 and move to the outer side of the annular shell 11 from the opening 16, so that the supporting spring 15 is clamped, and the garbage pressing fails, a set of baffle plate device is expected to be arranged for closing the opening 16 during pressing so as to solve the problem;

as a further scheme of the invention, a baffle groove 20 is vertically arranged on the inner wall of the ring shell 11 close to the upper end of the side wall of the opening 16, vertical sliding grooves 21 are vertically arranged on two opposite side walls of the baffle groove 20, a baffle 22 for closing the opening 16 is arranged on the side wall of the baffle groove 20, slide rods 23 are fixedly arranged on two side walls of the baffle 22, and the slide rods 23 are slidably arranged in the vertical sliding grooves 21;

when the garbage pressing device is used, when garbage is pressed, the side wall of the baffle 22 is pressed by the garbage, and along with the falling of the garbage, the sliding rods 23 at the two ends of the baffle 22 can fall along the vertical sliding groove 21 on the side wall of the baffle groove 20 (as shown in fig. 7, the friction force between the sliding rods 23 and the inner wall of the vertical sliding groove 21 is enough to support the baffle 22 not to slide down in a static state), so that the baffle 22 can move down in the baffle groove 20, the opening 16 is closed, and the problem that the garbage is extruded out of the annular shell 11 from the opening 16 in the pressing process to cause pressing failure is solved; secondly, since the compression stroke starts from the upper end of the equipment and is acted by the supporting spring 15, the supporting spring 15 can preferentially support the garbage space at the lower end, the garbage at the upper end is preferentially extruded, so that the baffle plate 22 can be preferentially driven to descend, and the garbage at the lower end is also extruded, so that the problem that the garbage is extruded from the opening 16 which is not completely closed is solved.

When the automatic resetting device is used, when equipment returns, the baffle 22 cannot be automatically reset, manual operation is needed, and the friction force between the sliding rod 23 and the inner wall of the vertical sliding groove 21 is worn and consumed along with the use of the equipment, so that the opening position of the upper end of the baffle 22 is difficult to maintain, and a set of automatic resetting device for the baffle 22 is expected to be arranged to solve the problems;

as a further scheme of the invention, two reset springs 24 are fixedly arranged on the upper end face of the baffle 22, the other ends of the reset springs 24 are fixedly arranged on the inner wall of the upper end of the baffle groove 20, a transverse locking hole 25 is transversely formed in the center of the baffle 22, a wedge block 26 is transversely arranged in the locking hole 25 in a sliding manner, the outer walls of the upper end and the lower end of the wedge block 26 at one end of the inner side of the ring shell 11 are provided with inclined planes 27, the side wall of the wedge block 26 at one end of the outer side of the ring shell 11 is in contact connection with a spring plate 28, and the two ends of the spring plate 28 are fixedly arranged on the inner side wall of the outer end of the locking hole 25;

when the invention is used, when the horizontal ring sleeve 13 descends, the wedge block 26 is preferentially extruded, so that the wedge block 26 drives the baffle plate 22 to downwards move against the action of the return spring 24 at the upper end, so as to close the opening 16, when the baffle plate 22 moves to the lowest limit position of the opening 16, the inclined surface of the wedge block 26 is extruded, so that the wedge block 26 outwards moves along the locking hole 25 against the elastic force of the spring plate 28, so as to ensure that the horizontal ring sleeve 13 and the ring plate 14 continuously press garbage, even completely pass through, so that the opening 16 can be automatically closed when the equipment presses, when the horizontal ring sleeve 13 and the ring plate 14 return, the reset can be automatically carried out under the action of the return spring 24, and when the horizontal ring sleeve 13 and the ring plate 14 move upwards from the lower end of the wedge block 26, the inclined surface 27 at the lower end of the wedge block 26 can be extruded and smoothly pass through, so as to avoid the problem of blocking.
