Description

Technical Field

[0001] The invention relates to the field of medical waste, and in particular to a medical waste bin. Background Art

[0002] Medical waste includes a lot of packaging bags, surgical gowns and other garbage that takes up a large area. This kind of garbage takes up a lot of space and is not convenient to place. Usually a few pieces of garbage take up more than half of the trash can, reducing the utilization rate of the trash can. If these garbage are pressed manually to ensure that medical waste can continue to be collected in the trash can, it is very unhygienic. The sharp medical waste in the trash can can easily scratch medical staff and cause cross infection.

[0003] The patent with publication number CN113525963A and name "A medical waste collection and treatment device capable of integrated collection and classification" discloses a solution to reduce the space occupied by such garbage by pressing. However, the solution does not consider using garbage bags to hold garbage in the garbage can. If garbage bags are not used, the garbage can must be disinfected and cleaned after each dumping of garbage. Otherwise, medical hygiene and safety cannot be guaranteed, which is very troublesome. Summary of the invention

[0004] The present invention aims to provide a medical waste bin which can not only compress packaging bags, surgical gowns and other garbage that occupy a large area, but also can be used in conjunction with garbage bags without damaging the garbage bags.

[0005] To achieve the above object, the present invention adopts the following technical solution: a medical waste bin, comprising a consumables bin, a collection bin and an operation chamber, wherein a plurality of consumables units are stored in the consumables bin, and the consumables units comprise a pressing plate, and a compressed garbage bag is arranged under the pressing plate;

[0006] The operating room is arranged above the consumable barrel and the collection barrel, and a transverse movement mechanism is provided in the operating room. The transverse movement mechanism is used for translation above the consumable barrel and the collection barrel, and a rotating lifting mechanism is provided on the transverse movement mechanism. The rotating lifting mechanism is connected to the fan, and the rotating lifting mechanism and the pressing plate are detachably connected. The rotating lifting mechanism is used to drive the pressing plate to lift and rotate; the fan is used to blow or suck air into the garbage bag.

[0007] The beneficial effects of this program are:

[0008] 1. In the initial state, the transverse movement mechanism is located above the collection bucket, the transverse movement mechanism, the rotary lifting mechanism, the pressing plate and the garbage bag are connected in sequence, and the fan blows air into the garbage bag, so that the garbage bag is inflated and then in an open state, and garbage can be thrown into the garbage bag at this time;

[0009] As the amount of garbage in the garbage bag increases, it enters a compressed state, and the rotating lifting mechanism drives the pressing plate to descend and rotate, driving the garbage bag to accelerate its rotation. There is garbage at the bottom of the garbage bag, and under the action of the inertia of the bottom, a speed difference is formed between the top and bottom of the garbage bag, causing the upper part of the garbage bag to be twisted into a spiral strip, thereby reducing the size of the opening above the garbage bag; at the same time, the pressing plate descends to the bottom of the collection barrel and presses the garbage bag to keep the upper part of the garbage bag in a spiral strip shape. The pressing plate not only blocks the opening above the garbage bag, but also compresses the garbage in the garbage bag, reducing the space occupied by the garbage bag.

[0010] The rotary lifting mechanism is disconnected from the pressing plate, and the rotary lifting mechanism moves into the consumable barrel and connects with the new pressing plate, driving the new pressing plate and the garbage bag to move above the collection barrel, and blowing air into the garbage bag to open the garbage bag in the collection barrel. At this time, the bottom of the garbage bag is suspended in the air or falls on the previously used garbage bags. The used garbage bags are compressed and stacked in turn. Finally, when they are filled to a certain extent, the garbage bags in the collection barrel are taken out for collective processing, and the pressing plate is recycled and disinfected for reuse.

[0011] Thereby, the garbage that occupies a large area, such as packaging bags and surgical gowns, can be compressed and can be used in conjunction with garbage bags without damaging the garbage bags.

[0012] 2. Plastic garbage bags are easily deformed, but this solution uses a pressing plate and a garbage bag as a combination of consumables to achieve the effect of automatically replenishing the garbage bag by moving the pressing plate.

[0013] 3. To facilitate stacking, the garbage bag is folded in the consumable barrel, with the bag opening facing upwards; to facilitate use, when the garbage bag is in the collection barrel, the fan blows air into the garbage bag to open the inside of the garbage bag for easy garbage input.

[0014] 4. The garbage bag can be opened by blowing and sucking air from the fan, which is convenient and quick without manual intervention.

[0015] 5. Compress multiple garbage bags and place them at the bottom of the collection bucket in order to maximize the use of the internal space of the collection bucket.

[0016] Furthermore, a first garbage outlet is opened on the upper side of the collecting barrel, and a second garbage outlet is opened on the upper side of the garbage bag. After the transverse movement mechanism drives the pressing plate and the garbage bag to move to the top of the collecting barrel, the fan box blows air into the garbage bag, and after the garbage bag is inflated, the first garbage outlet is connected to the second garbage outlet.

[0017] Furthermore, a double-sided tape is provided on the edge of the first garbage opening, and after the garbage bag is inflated, the edge of the second garbage bag is adhered to the double-sided tape.

[0018] Furthermore, the transverse movement mechanism includes a translation block, a transverse movement motor and a screw pair, the screw pair includes a horizontal and parallel threaded rod and a guide rod, the output shaft of the transverse movement motor is connected to the end of the threaded rod, the threaded rod passes through the translation block and is threadedly connected to the translation block, and the guide rod passes through the translation block and is slidably connected to the translation block.

[0019] Furthermore, the rotary lifting mechanism includes a rotary motor, a rotary disk and a connecting disk, the rotary motor is arranged on the translation block, the lower end of the output shaft of the rotary motor is dynamically connected to the center position of the rotary disk, a plurality of telescopic rods are arranged between the rotary disk and the connecting disk, a plurality of hooks are arranged on the lower side of the connecting disk, and a plurality of hanging rings are arranged on the upper side of the pressing plate;

[0020] When the connecting disk and the pressing plate are in contact, the connecting disk rotates forwardly, and the hooks are respectively inserted into the hanging rings to vertically connect the connecting disk and the pressing plate; when the connecting disk rotates reversely, the hooks are respectively withdrawn from the hanging rings to disconnect the connecting disk and the pressing plate.

[0021] Furthermore, a first air inlet, a second air inlet and a third air inlet are sequentially opened in the middle of the rotating disk, the connecting disk and the pressing plate, the fan comprises an air duct, an end of the air duct is connected to the first air inlet, a bellows is connected between the first air inlet and the second air inlet, a second air inlet duct is provided on the lower side of the connecting disk, the second air inlet duct is used for connecting with the third air inlet, the bag opening of the garbage bag is located below the third air inlet, the air duct, the first air inlet, the bellows, the second air inlet, the third air inlet and the garbage bag are sequentially connected to form an air duct.

[0022] Furthermore, a plurality of first limiting plates are provided on the side wall of the collecting barrel, and the plurality of first limiting plates are arranged at the same level of the collecting barrel with equal height difference, and a second limiting plate is provided on the side of the pressing plate.

[0023] When the rotating motor drives the rotating disk, the connecting disk and the pressing plate to rotate forward in sequence, the second limit plate passes through the first limit plates at different heights; after the second limit plate stops between the two first limit plates, the connecting disk rotates in the opposite direction, the telescopic rod drives the connecting disk to move upward, and the second air inlet pipe on the connecting disk is pulled out from the third air inlet.

[0024] Furthermore, the third air inlet is a trumpet-shaped through hole that expands downward, and a diverter block is provided at the center of the lower opening of the third air inlet. The diverter block is used to disperse the wind blown by the fan, and a plurality of connecting rods are provided between the diverter block and the bottom of the side wall of the third air inlet.

[0025] Furthermore, it also includes a controller, which is connected to the rotating motor, the lateral movement motor and the telescopic rod respectively; the working state of the controller includes an initial state, a compression state and a reset state;

[0026] In the initial state, the translation block is above the collection bucket, the telescopic rod between the rotating disk and the connecting disk is shortened to the shortest, the connecting disk and the pressing plate are connected by a hook and a hanging ring, and after the air duct blows air to the garbage bag, the garbage bag is in an open state, and the second garbage outlet of the garbage bag is connected to the first garbage outlet of the collection bucket;

[0027] In the compressed state, the height of the garbage in the garbage bag approaches the second garbage opening, the telescopic rod extends, and the rotating motor drives the pressing plate to accelerate forward rotation; then, the speed of the rotating motor decreases, and when the second limit plate moves between the two first limit plates, the rotating motor completely stops rotating. At the same time, the fan sucks air to form negative pressure, which draws the air out of the garbage bag. The telescopic rod continues to extend, and the pressing plate presses the garbage bag and the garbage to the bottom of the collection bin;

[0028] In the reset state, the rotating motor drives the connecting disk to reverse, the telescopic rod shortens, the connecting disk and the pressing plate separate, and the transverse motor drives the threaded rod to rotate, driving the translation block to move above the consumable barrel; then, the telescopic rod extends until the connecting disk contacts the new pressing plate, and the rotating motor drives the connecting disk to rotate forward, and the connecting disk and the pressing plate are connected by a hook and a hanging ring; next, the telescopic rod shortens, and the transverse motor drives the threaded rod to rotate, driving the translation block to move above the collection barrel; the air duct blows air to the garbage bag, and the garbage bag is in an open state.

[0029] This solution also has the following effects:

[0030] 1. In order to facilitate the fan to blow air from the top of the garbage bag opening, this solution sets a second garbage opening on the side of the garbage bag, so that garbage can be put into the garbage bag from the second garbage opening;

[0031] 2. After the fan blows air to open the garbage bag, in order to prevent the garbage in the garbage bag from being blown out, the fan cannot continue to blow air, and after the blowing stops, a gap will be formed between the garbage bag and the collection bin; in order to prevent the garbage from being thrown into the gap, the garbage bag and the edge of the first garbage opening of the collection bin are glued together by double-sided tape while blowing air, so that the garbage can be smoothly thrown into the garbage bag; after the garbage bag is full, the rotating lifting mechanism directly rotates to pull the garbage bag and the double-sided tape apart;

[0032] When the double-sided adhesive tape is not sticky enough, it can be directly observed from the first garbage outlet that the garbage bag is not stuck, and it is also very convenient to manually replace the double-sided adhesive tape.

[0033] 3. The vertical connection and disconnection of the hanging ring and the hook are realized by forward and reverse rotation, thereby realizing the detachable connection of the rotating lifting mechanism and the pressing plate.

[0034] 4. In the compressed state, the pressing plate descends and rotates at the same time to avoid direct contact between the first limit plate and the second limit plate. When the pressing plate moves to the bottom, the second limit plate moves between the two first limit plates. At this time, the connecting plate and the pressing plate are separated, the pressing plate loses pressure, and the compressed garbage in the garbage bag rebounds upward, while the first limit plate prevents the pressing plate from moving upward through the second limit plate, thereby maintaining the compression state of the garbage.

[0035] 5. In this scheme, the first air inlet, the second air inlet and the third air inlet are arranged in sequence so that the fan can blow air to the garbage bag under the pressing plate. If a gust of wind is blown out directly, it will only stretch the garbage bag, narrow the bag body, reduce the capacity of the garbage bag, and prevent the garbage bag from contacting with the double-sided tape. In this scheme, a diverter block is provided at the center of the lower mouth of the third air inlet to disperse the wind blown by the fan to the surroundings of the garbage bag, so that the garbage bag collides with the surroundings and opens, maximizing the volume of the garbage bag, making the garbage bag contact with the double-sided tape, preventing the formation of a gap between the garbage bag and the collection bin, and preventing garbage from falling from the gap and contaminating the inner wall of the collection bin.

[0036] 6. In the compressed state, the upper part of the garbage bag twists into a spiral strip, and the pressing plate presses the garbage bag. Once the pressing plate loses its pressing force, the upper part of the garbage bag may slide relative to the pressing plate, thereby opening the large bag mouth at the upper part of the garbage bag and causing the garbage to scatter;

[0037] In the present solution, while the pressing plate presses the garbage bag, the fan sucks away the air in the garbage bag so as to better compress the garbage in the garbage bag. In the process of the pressing plate pushing the garbage bag downward, the inside of the garbage bag gets closer and closer to the third air inlet. At this time, the fan sucks a part of the upper part of the garbage bag through the third air inlet between the diverter block and the side wall of the third air inlet, and this part is stuck by the connecting rod; when the pressing plate presses the garbage bag to the lowest position, the stuck part of the garbage bag protrudes relative to the other parts, thereby horizontally limiting the stuck part of the garbage bag through the third air inlet, thereby preventing the upper bag opening of the garbage bag from opening, avoiding garbage from scattering, and ensuring that the inside of the collection bin is not contaminated by garbage.

[0051] Example

[0052] The embodiment is basically as follows Figure 1-Figure 11 As shown: A medical waste bin, comprising a rectangular waste bin body 1 and a fan, as shown Figure 1 , Figure 4 As shown, a partition plate 11 is provided inside the trash can body 1, and the partition plate 11 divides the lower part of the interior of the trash can body 1 into two areas. The two areas respectively form a consumable barrel 2 and a collection barrel 5. An operating room 3 is formed on the upper part of the trash can body 1. The inner side of the collection barrel 5 and the partition plate 11 is a cylindrical space, and a plurality of consumable units are stacked in the consumable barrel 2.

[0053] The consumables unit includes a pressing plate 21 and a garbage bag 12. Fig.10As shown, the pressing plate 21 is disc-shaped, and a third air inlet 22 is opened at the center of the pressing plate 21. The third air inlet 22 is a trumpet-shaped through hole with the mouth expanded downward. A hemispherical diverter block 23 is provided at the center of the lower mouth of the third air inlet 22. The diverter block 23 is used to disperse the wind blown by the fan. Four connecting rods 24 are circumferentially welded between the diverter block 23 and the bottom of the side wall of the third air inlet 22, and a second limit plate 25 is symmetrically welded on the side of the pressing plate 21.

[0054] like Fig. 9 , Fig.10 As shown, four hanging rings 26 are welded on the upper circumference of the pressing plate 21, and the holes of the hanging rings 26 are oriented in the circumference of the pressing plate 21; a plurality of lifting hooks 27 ( Fig.10 Not shown, only Fig. 9 In this embodiment, the number of the lifting hooks 27 is 2, and two lifting holes and a second garbage opening are opened on the upper part of the garbage bag 12. The height of the second garbage opening is lower than the height of the lifting hole. The second garbage opening is used to allow garbage to enter the garbage bag 12, and the lifting hole is used to hang on the lifting hook 27;

[0055] The garbage bag 12 is divided into a compressed state, an open state and a twisted state. In the compressed state, Figure 1 As shown in the garbage bag 12 in the left consumable barrel 2, the bag mouth of the garbage bag 12 faces upward, and the bag body of the garbage bag 12 is folded and compressed into a corrugated structure, that is, a structure similar to that of the bellows 13 when it is compressed; in the open state, as shown in FIG. Figure 1 As shown in the garbage bag 12 in the right collection bucket 5, the bag body of the garbage bag 12 is spread out to accommodate the garbage. Figure 2 As shown in the garbage bag 12 in the right collecting bucket 5 , the upper portion of the garbage bag 12 is twisted into a spiral strip shape, thereby reducing the size of the opening above the garbage bag 12 .

[0056] like Figure 1As shown, the operating room 3 is located above the consumable barrel 2 and the collection barrel 5, and a transverse movement mechanism is provided in the operating room 3. The transverse movement mechanism is used for translation above the consumable barrel 2 and the collection barrel 5. Steps 31 are provided on both sides of the operating room 3, and the steps 31 span the consumable barrel 2 and the collection barrel 5. The transverse movement mechanism includes a translation block 32, a transverse movement motor 34 and a screw pair. Two wheels are respectively installed on the front and rear sides of the translation block 32, and the two wheels are both arranged on the steps 31. The wheels are used to roll on the steps 31 in the direction of the steps 31. The limiting device for preventing the wheel from shifting in the moving direction is a prior art The screw pair includes a horizontal and parallel threaded rod 33 and a guide rod, which is not shown in the figure. The transverse motor 34 is bolted to the left side wall of the operating room 3, and the output shaft of the transverse motor 34 is welded to the end of the threaded rod 33. The threaded rod 33 passes through the translation block 32 and is threadedly connected to the translation block 32. The right end of the threaded rod 33 is inserted into the side wall of the operating room 3 and is rotatably connected to the side wall of the operating room 3. The guide rod passes through the translation block 32 and is slidably connected to the translation block 32 (the guide rod is omitted in the figure), and the left and right ends of the guide rod are fixedly connected to the side walls of the operating room 3 respectively.

[0057] like Figure 8 , Fig.11 As shown, a rotating lifting mechanism is provided on the translation block 32, and the rotating lifting mechanism is used to drive the pressing plate 21 to lift and rotate. The rotating lifting mechanism includes a rotating motor 41, a driving gear 42, a driven gear 43, a rotating disk 44 and a connecting disk 49. The driving gear 42 and the driven gear 43 are both arranged in the translation block 32, and the rotating disk 44 is rotatably arranged at the lower side of the translation block 32. The rotating motor 41 is bolted to the translation block 32, and the lower end of the output shaft of the rotating motor 41 passes through the connecting block and is key-connected with the driving gear 42, and the driving gear 42 and the driven gear 43 are meshed;

[0058] A first air inlet pipe 45 is welded to the upper surface of the rotating disk 44 at the center position. The first air inlet pipe 45 passes through the rotating disk 44 to form a first air inlet. The first air inlet pipe 45 passes through the driven gear 43 and is welded to the driven gear 43. The upper end of the first air inlet pipe 45 is inserted into the translation block 32 and is rotationally connected to the translation block 32. The translation block 32 vertically supports the upper end of the first air inlet pipe 45. The rotation connection and vertical support are both conventional settings and are not repeated here. Four telescopic rods 46 are circumferentially bolted between the rotating disk 44 and the connecting disk 49. Four hooks 48 are circumferentially welded to the lower side of the connecting disk 49. The hooks 48 are used to cooperate with the hanging ring 26 on the pressing plate 21. When the connecting disk 49 rotates forward, the hooks 48 are horizontally inserted into the hanging ring 26 to vertically connect the connecting disk 49 and the pressing plate 21; conversely, the hooks 48 horizontally withdraw from the hanging ring 26. In this embodiment, the forward rotation is a clockwise rotation when viewed from above.

[0059] The fan includes an air duct, an end of which passes through the translation block 32 and is plugged into the first air inlet duct 45 (the fan and the air duct are not shown in the figure), the first air inlet duct 45 is welded on the lower surface of the connecting plate 49 at the center position, the second air inlet duct 47 passes through the connecting plate 49 to form a second air inlet, and a bellows 13 is connected between the first air inlet and the second air inlet. The second air inlet duct 47 is used to be plugged into the third air inlet 22. There is friction between the second air inlet duct 47 and the third air inlet 22. The second air inlet duct 47 can be pulled out from the third air inlet 22 only under the action of a certain external force. The bag opening of the garbage bag 12 is located below the third air inlet 22. The air duct, the first air inlet, the bellows 13, the second air inlet, the third air inlet 22 and the garbage bag 12 are connected in sequence to form an air duct, and the fan blows or inhales air into the garbage bag 12 through the air duct.

[0060] like Figure 1 As shown, a first garbage opening 51 is opened on the right side of the upper part of the collecting bucket 5, and a garbage door (not shown) is provided on the front side of the collecting bucket 5 to facilitate taking out the garbage bag containing garbage in the collecting bucket; a double-sided tape is adhered to the lower edge of the first garbage opening 51, and when the garbage bag 12 is in an open state, the second garbage opening 51 is located on the right side of the upper part of the garbage bag 12, and the edge of the second garbage bag 12 is adhered to the double-sided tape, and the first garbage opening 51 and the second garbage opening are connected, and the path direction of garbage thrown into the garbage bag 12 is as shown in FIG. Figure 1 As shown by the arrow, the position where the arrow and the garbage bag intersect is the position of the second garbage outlet.

[0061] A plurality of first limit plates 52 are arranged on the right side of the partition plate 11. The plurality of first limit plates 52 are arranged at the same horizontal position of the collection barrel 5 with equal height difference, that is, the projections of the plurality of first limit plates 52 in the horizontal direction overlap, and the number of the first limit plates 52 is determined according to the size of the collection barrel 5 and the first limit plates 52. When the rotating motor 41 drives the rotating disk 44, the connecting disk 49 and the pressing plate 21 to rotate forward in sequence, the second limit plate 25 passes through the first limit plates 52 of different heights; after the second limit plate 25 stops between the two first limit plates 52, the connecting disk 49 rotates in the opposite direction, the telescopic rod 46 drives the connecting disk 49 to move upward, and the second air inlet pipe 47 on the connecting disk 49 is pulled out from the third air inlet 22.

[0062] The controller is also included. The controller is arranged in the operating room 3 (not shown in the figure). The controller is connected to the rotating motor 41, the lateral movement motor 34 and the telescopic rod 46 respectively. The rotating motor 41 and the lateral movement motor 34 are servo motors. The working state of the controller includes an initial state, a compression state and a reset state.

[0063] In the initial state, if Figure 1As shown, the translation block 32 is above the collection bucket 5, the telescopic rod 46 between the rotating disk 44 and the connecting disk 49 is shortened to the shortest, the connecting disk 49 and the pressing plate 21 are connected by the hook 48 and the hanging ring 26, and after the air duct blows air to the garbage bag 12, the garbage bag 12 is in an open state, and the second garbage opening of the garbage bag 12 is connected to the first garbage opening 51 of the collection bucket 5;

[0064] In the first stage of compression, Figure 2 As shown, the height of the garbage in the garbage bag 12 is close to the second garbage opening, the telescopic rod 46 is extended, the rotary motor 41 drives the pressing plate 21 to accelerate forward rotation, there is garbage at the bottom of the garbage bag 12, and under the action of the inertia of the bottom, the top and bottom of the garbage bag 12 form a speed difference, and the garbage bag 12 changes to a twisted state; in the second stage of the compression state, as shown in FIG. Figure 3 As shown, the rotation speed of the rotating motor 41 decreases, and when the second limit plate 25 moves between the two first limit plates 52, the rotating motor 41 completely stops rotating. At the same time, the fan sucks air to form a negative pressure, which draws the air out of the garbage bag 12. The telescopic rod 46 continues to extend, and the pressing plate 21 presses the garbage bag 12 and the garbage to the bottom of the collection bucket 5.

[0065] In the first stage of the reset state, if Figure 4 As shown, the rotating motor 41 drives the connecting plate 49 to reverse, and the telescopic rod 46 shortens. Due to the obstruction of the first limit plate 52, the connecting plate 49 and the pressing plate 21 overcome the friction between the second air inlet pipe 47 and the third air inlet 22, and then separate. In the second stage of the reset state, as shown in FIG. Figure 5 As shown, the traverse motor 34 drives the threaded rod 33 to rotate, driving the translation block 32 to move above the consumable barrel 2; in the third stage of the reset state, as shown Figure 6 As shown, the telescopic rod 46 is extended until the connecting plate 49 contacts the new pressing plate 21, and the new pressing plate 21 is hung with a compressed garbage bag 12, and the rotating motor 41 drives the connecting plate 49 to rotate forward, and the connecting plate 49 and the pressing plate 21 are connected through the hook 48 and the hanging ring 26; in the fourth stage of the reset state, as shown Figure 7 As shown, the telescopic rod 46 is shortened, and the transverse motor 34 drives the threaded rod 33 to rotate, driving the translation block 32 to move above the collection bucket 5; the air duct blows air to the garbage bag 12, and the garbage bag 12 is in an open state.

[0066] When the garbage bags in the collection bin are full, open the garbage door on the front side and take out the garbage bags containing garbage in the collection bin.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
