Description

Technical Field

[0001] The present invention belongs to the field of medical waste bins, and particularly relates to a medical self-cleaning waste bin. Background Art

[0002] Generally, medical waste bins are ordinary waste bins with disposable plastic bags for holding waste. When the waste bin is full of waste, the whole plastic bag can be taken away. The following functions are also required during use:

[0003] Large, shell-shaped or strip-shaped waste can be shredded to increase the waste loading capacity of the waste bin. In the prior art, a waste shredder is added to the waste bin. However, when the shredder shreds waste such as residual blood, turbid liquid or viscous substances, the inner cavity of the shredder is extremely easy to get dirty and generate odors. The way to solve this problem in the prior art is to clean the inner cavity of the shredder with water, but this cleaning method uses a large amount of water, resulting in a large amount of waste water that needs to be treated additionally. If this waste water is discharged into the plastic bag, it will increase the weight of the plastic bag.

[0004] In the prior art, the shredder provided on the waste bin shreds all the waste to be put into the waste bin without discrimination. The waste that enters the shredder and does not need to be shredded will cause the shredder to be overused. In view of this situation, usually a common waste bin for holding waste that does not need to be shredded is set beside, and the waste is selectively shredded through classification, which will increase the space required for placing the waste bin. If an existing double-chamber waste bin is used, a shredder is installed on one chamber and no shredder is installed on the other chamber. Although the problem of large floor space can be solved, since the proportion of waste that needs to be shredded and waste that does not need to be shredded cannot be determined, the space in the double-chamber waste bin cannot be fully utilized.

[0005] The present invention designs a medical self-cleaning waste bin to solve the above problems. Summary of the Invention

[0036] As Figure 5 shown in Fig., the telescopic rod 15 is composed of an inner rod 18 and an outer sleeve 16 which are sleeved with each other.

[0037] As Figure 3 shown in Fig., a hopper 26 is provided at the upper end of the cylinder 25; a lid B30 for opening and closing the hopper 26 is hinged at the upper end of the hopper 26, and a handle 21 is installed on the lid B30.

[0038] As Figure 3 , 4 shown in Fig., a rotating shaft 37 which is in transmission connection with the output shaft of the motor 39 is rotatably sealed in a circular groove in the middle of the lower end of the cone 31; two blades 38 are installed on the rotating shaft 37.

[0039] As shown Figure 3 in the figure, a gear A40 is installed on the rotating shaft 37. The gear A40 meshes with two gears B41 that are circumferentially spaced 180 degrees apart on the inner circumference of the ring sleeve D36, and the two gears B41 mesh with the toothed ring 42 at the lower end of the conical cylinder 31.

[0040] As shown Figure 4 in the figure, a guiding groove 33 for guiding water into the water through-hole 32 is installed at the water through-hole 32 on the outer wall of the conical cylinder 31.

[0041] As shown Figure 2 in the figure, a shielding groove 34 that blocks the garbage in the conical cylinder 31 from leaking out through the water through-hole 32 and does not block the water entering the conical cylinder 31 from the water through-hole 32 is installed at the water through-hole 32 on the inner wall of the conical cylinder 31.

[0042] As shown Figure 3 in the figure, there is a structure for locking between the lid B30 and the barrel body 1 in the present invention when the lid B30 closes the inlet A5.

[0043] Working process of the present invention: In the initial state, the crushing mechanism 24 is not installed at the inlet B7, the lid A20 is in the closed state for the inlet A5, and the return springs 17 of the two telescopic rods 15 are both in the natural state. Each connecting rod A12 and the corresponding connecting rod B13 are both in the concave state. The partition plate 10 is located in the middle of the barrel body 1, dividing the barrel body 1 into two equal parts.

[0044] As shown Figure 6 、 7 in the figure, when it is necessary to use the present invention to classify the garbage to be crushed and the garbage not to be crushed, garbage bags 44 are first installed in the two spaces corresponding to the inlet A5 and the inlet B7. The bag mouth of the garbage bag 44 in the space corresponding to the inlet A5 is rolled up on the ring sleeve A6, and the ring sleeve C9 is nested on the ring sleeve A6 to fix the bag mouth of the corresponding garbage bag 44. The bag mouth of the garbage bag 44 in the space corresponding to the inlet B7 is rolled up on the ring sleeve B8, and the ring sleeve D36 of the crushing mechanism 24 is nested on the ring sleeve B8 to fix the bag mouth of the corresponding garbage bag 44. The ring groove A27 on the cylinder 25 is communicated with the water tank 22 through two water pipes 23 to form a water cycle.

[0045] When it is necessary to crush and collect the garbage to be crushed, the motor 39 in the crushing mechanism 24 is started. The motor 39 drives the two blades 38 to rotate rapidly through the rotating shaft 37. At the same time, the rotating shaft 37 drives the conical cylinder 31 to rotate rapidly relative to the cylindrical cylinder 25 through the gear A40, the two gears B41, and the gear ring 42. The rotation direction of the conical cylinder 31 is opposite to that of the blades 38, so that the relative rotation speed of the blades 38 and the conical cylinder 31 increases. The water in the water tank 22 enters the annular groove A27 through the water pipe 23 communicated with the water pump and fills the annular groove A27. The water in the annular groove A27 enters the annular gap between the conical cylinder 31 and the cylindrical cylinder 25 in a small amount. The guiding groove 33 on the outer wall of the rapidly rotating conical cylinder 31 guides the water in the annular gap into the conical cylinder 31 through the water passing hole 32.

[0046] Then, the lid B30 is opened, and the garbage to be crushed is put into the conical cylinder 31 and mixed with the small amount of water entering the conical cylinder 31. The garbage entering the conical cylinder 31 is effectively crushed by the rapidly rotating blades 38 and mixed with the small amount of water in the conical cylinder 31 to form a fluid crushed garbage. At the same time, the fluid crushed garbage in the conical cylinder 31 after being crushed enters the annular groove B28 through the discharge port B43 under the action of centrifugal force and enters the garbage bag 44 corresponding to the inlet B7 through the discharge port A29 and the discharge pipe 35.

[0047] After the garbage in the conical cylinder 31 is crushed and discharged clean under the action of centrifugal force, the water passing holes 32 on the wall surface of the continuously rotating conical cylinder 31 continue to infiltrate water. The water infiltrating into the conical cylinder 31 self-cleans the inner wall of the conical cylinder 31 and enters the annular groove B28 through the discharge port B43 to self-clean the inner wall of the annular groove B28. The waste water in the annular groove B28 is discharged into the corresponding garbage bag 44 through the discharge port A29 and the discharge pipe 35 for recycling.

[0048] When it is necessary to recycle the garbage that does not need to be crushed, the lid B30 is opened. The lid B30 drives the partition plate 10 to squeeze the space corresponding to the inlet B7 through the fixed rod 19, the telescopic rod 15, the connecting rod A12, and the connecting rod B13, so that the space corresponding to the inlet A5 is enlarged, which is convenient for putting more garbage that does not need to be crushed into the garbage bag 44.

[0049] After the placement of the garbage that does not need to be crushed is completed, the lid B30 closes the inlet A5 and locks the lid B30. The lid B30 drives the partition plate 10 to reset through a series of transmissions. Since the amount of garbage in the garbage bag 44 corresponding to the inlet A5 is large and prevents the partition plate 10 from resetting, the two telescopic rods 15 are compressed, and the two return springs 17 in the telescopic rods 15 are adaptively deformed, so as to keep the space corresponding to the inlet A5 unchanged as a large space. Thus, the two spaces of the barrel body 1 can be effectively utilized.

[0050] In summary, the beneficial effects of the present invention are as follows: The partition 10 in the barrel body 1 of the present invention can be changed at any time under the condition of the change of the garbage proportion in the two cavities, and the two cavities adaptively change according to the proportion of the types of garbage contained, so as to achieve the purpose of making full use of the space of the two cavities in the trash can.

[0051] The present invention adopts a double-cavity design, which saves the floor space of the trash can.

[0052] While effectively crushing the classified large pieces, shell-shaped or strip-shaped garbage, the crushing mechanism 24 in the present invention will self-clean the inner wall of its own inner cavity through a small flow of clean water, saving water resources and not causing a significant increase in the weight of the garbage bag 44 used to hold the crushed garbage. At the same time, it avoids the generation of peculiar smell in the inner cavity of the crusher due to the crushing of garbage such as residual blood, turbid liquid or viscous substances, and has outstanding environmental protection functions.
