Description

Technical Field

[0001] The utility model relates to the technical field of trash cans, in particular to an intelligent trash can. Background Art

[0002] Since the plastic film tube material of the ring-shaped packaging has the characteristic of having its own opening, it is convenient for the garbage bin to realize automatic bag feeding and is adopted by some utility model developers. Therefore, the garbage bin in the prior art usually contains a garbage bag storage device, a flip cover is provided on the upper part of the garbage bag storage device, a garbage bag sealing device is provided on the lower part of the garbage bag storage device, and the barrel body is below the sealing device. In addition, the garbage bin in the prior art is also provided with a bag feeding device, which is arranged at a corresponding position of the garbage bin according to different bag feeding methods.

[0003] The above-mentioned annularly packaged plastic film tube material is a long tube or long tube of plastic film, usually several meters to dozens of meters, packaged in an annular or quasi-annular packaging box, one end of which is drawn out from the circumferential opening of the packaging box and sealed, serving as the bottom of the first garbage bag, and the inner hole of the annular packaging box is the garbage input port. Each time the garbage bag is sealed, the garbage bag sealing device closes the garbage bag opening and performs heat-melt cutting, which generates two seals. The lower seal is the seal of the old garbage bag that has been filled, and the upper seal is the bottom of the new garbage bag that is about to be used. After the user takes out the old garbage bag, the bag feeding device will automatically lay a new garbage bag.

[0004] For example, the utility model patent with Chinese patent number CN202221912701.9 discloses a garbage bag closing heat sealing device and a garbage can, the utility model patent with Chinese patent number CN201920784503.0 discloses an automatic sealing mechanism for garbage bags of an intelligent garbage can, and the utility model patent with Chinese patent number CN202021000309.8 discloses a garbage bag closing mechanism. When working, the above-mentioned public documents gather the plastic film of the garbage bag to the middle position of the garbage can mouth. Since multiple cross bars need to perform linear motion and the cross bars have relatively high rigidity requirements when in use, the structure is complex, the volume is large, and the cost is relatively high.

[0005] For example, the utility model patent with Chinese patent number CN201921512762.4 discloses an intelligent trash can that automatically closes according to the amount of garbage, the utility model patent with Chinese patent number CN201822046732.0 discloses a garbage bag packaging mechanism and an intelligent trash can, and the utility model patent with Chinese patent number CN201921886151.6 discloses a structure for closing the garbage bag on a trash can and a trash can made of the same. When working, the above-mentioned public documents gather the plastic film of the garbage bag to a corner of the trash can mouth. Compared with the linear motion of multiple cross bars, its structure is simple, the volume is small, and the cost is low. However, the unidirectional and unilateral bag gathering may cause uneven folding distribution of the plastic film, with more folding on the side close to the moving edge and less folding on the side close to the fixed edge, and the opening of the plastic film of the garbage bag cannot be evenly closed. Folding too little will make the hot-melt seal of the plastic film relatively thin, and the seal will be easily torn.

[0006] In addition, the trash cans in the prior art are all provided with a lid, and the lid is generally opened and closed by flipping upward. However, the flip-up opening and closing structure occupies a large volume, is complex to assemble, and is costly. At the same time, in order to realize automatic replacement of the garbage bag, a fan is provided on the lid to blow the garbage bag into the trash can, but the weight of the lid is increased, and the center of gravity will shift significantly after the lid is flipped open, which may easily cause the trash can to tip over.

[0032] The usage of the above-mentioned smart trash can is as follows:

[0033] The top cover is flipped and opened and closed on the rear side of the top of the cover body by the driving of the top cover driving assembly, and the cover body is flipped and opened and closed on the rear side of the top of the barrel body by the driving of the cover body driving assembly.

[0034] When the top cover is opened, the user can put garbage into the garbage bag inside the barrel body, replace the annular film tube garbage bag in the bag groove, and take the sealed garbage bag out of the barrel body.

[0035] In the initial state, the hot melt sealing assembly is hinged open and will not block the lid opening, the barrel opening of the barrel body, or the opening of the garbage bag.

[0036] The closing drive assembly works and drives the closing rotating belt to rotate along the cover trajectory, and the closing rotating belt drives the flexible closing line to be pulled out during the rotation, and during the entire rotation process of the closing rotating belt, the flexible closing line is always in a linear tensioned state, and closes the garbage bag opening on the cover; when the closing rotating belt rotates to the initial position, the flexible closing line closes the garbage bag opening between the hot-melt sealing assemblies, and the sealing drive assembly works and drives the hot-melt sealing assembly to perform horizontal hinged closure, vertical hinged closure, or inclined hinged closure along the opening of the cover, and the hot-melt sealing assembly performs hot-melt sealing on the closed garbage bag opening when closing.

[0037] The flexible closing line and the hot-melt sealing assembly realize normal closing and sealing of the garbage bag when the cover is closed, or realize overload closing and sealing of the garbage bag when the cover is opened.

[0038] The sealed garbage bag and the annular film tube garbage bag are separated by hot-melt sealing assembly, separated from each other by flipping open the cover, or manually separated from each other after the cover is flipped open.

[0039] The cover body is flipped and closed after the garbage bag is taken out of the barrel body, and then the volute fan starts to work and discharges the air inside the barrel body to the bottom of the barrel body, so that a negative pressure state is formed inside the barrel body. At this time, under the action of atmospheric pressure, the annular membrane tube garbage bag is drawn out of the bag groove and enters the barrel body to complete the automatic paving of the garbage bag.

[0040] The utility model has the following advantages compared with the prior art through the improvement of the above structure:

[0041] First, the flexible closing line is set on the closing rotating belt, and the closing driving component is used to drive the closing rotating belt to rotate along the trajectory of the cover, so that the flexible closing line can move together and the opening of the garbage bag can be automatically closed. This not only reduces the number of components of the closing device and reduces the production cost, but also because the closing rotating belt itself is soft, it can greatly reduce the processing and assembly accuracy requirements. In addition, the flexible closing line can cover the entire cover when the closing rotating belt rotates along the trajectory of the cover, which not only closes the garbage bag with a wide opening and a large thickness, improves the applicability of the product, but also reduces the closing errors of the garbage bag.

[0042] 2. The closing rotating belt is flexible and can rotate along the track of the cover in any shape, so that the flexible closing line can cover the entire cover and close the mouth of the garbage bag. Therefore, the shape of the cover is not restricted. It not only provides better design creativity for the appearance of the trash can, but also improves the flexibility of the closing rotating belt and the flexible closing line during work, avoiding jamming and loosening problems during work, and ensuring that the mouth of the garbage bag is closed effectively and evenly.

[0043] 3. Using the sealing drive assembly to drive the hot melt sealing assembly to achieve hinged opening and closing not only reduces the number of components of the sealing device and reduces production costs, but also the hinged cooperation of the hot melt sealing assembly can achieve a wide range of angles within a short range of activity, which not only meets the requirements of sealing garbage bags with wide openings, but also reduces the power consumption of the hot melt sealing assembly during activity, reduces the cost of use, and the hot melt sealing assembly will not vibrate, make abnormal noises, etc. when hingedly opened and closed, thereby improving the user experience.

[0044] 4. The hot melt sealing component adopts a hinged closure method to cover the single side area of ​​the cover. Combined with the flexible closing line, the flexible side of the cover can be gathered in the entire range. This can effectively avoid the problem of thin hot melt sealing in some parts due to uneven folding position when closing the garbage bag, so as to improve the sealing stability.

[0045] 5. The top cover drive assembly, the lid body drive assembly, the closing drive assembly and the sealing drive assembly are arranged on the same side, so that the garbage bag can be closed and sealed on the same side of the lid opening, and the lid body and the top cover can be flipped and opened and closed on the same side. This not only effectively reduces the space occupied by the top cover drive assembly, the lid body drive assembly, the closing drive assembly and the sealing drive assembly on the barrel body and the lid body, improves the compactness of the coordination between the components, but also reduces the overall weight of the lid body.

[0046] 6. Use the volute fan to extract the air inside the barrel, so that a negative pressure state is formed inside the barrel, so that the annular membrane tube garbage bag can be automatically laid inside the barrel, and the air extracted by the volute fan is directly discharged to the bottom of the barrel. This not only avoids the problem that the volute fan in the prior art is set on the top of the garbage can, which makes the garbage can easily tip over when used, so as to improve the stability of the garbage bag. At the same time, since the air is discharged to the bottom of the barrel, there is no need to consider the obstruction of the exhaust port, so that the garbage can can be placed in any position at will to reduce space occupancy. In addition, the volute fan is silent and efficient when working, and can extract the air inside the barrel in a shorter time, thereby completing the automatic and rapid laying of the garbage bag to improve the user experience.

[0047] 7. Since the top cover drive assembly, the cover body drive assembly, the closing drive assembly and the sealing drive assembly utilize mechanical transmission, liquid transmission, electric transmission, or magnetic transmission to output power, there are more feasible schemes for power transmission between each other, so that production, processing and assembly can be adjusted according to implementation needs, with higher flexibility, good transmission efficiency, simple structure, lower production cost and assembly precision requirements.

[0075] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0076] See also Figure 1-Figure 30The smart trash can includes a cover body 2 arranged on a trash can body 40.

[0080] A cover driving assembly is provided between the cover body 2 and the barrel body 40, and the two are hingedly connected through the cover driving assembly.

[0081] The cover body 2 is provided with a closing device, which includes a closing drive assembly, a closing rotating belt 3, and a flexible closing line 4. The closing drive assembly drives the closing rotating belt 3 to rotate along the track of the cover opening 1, and the closing rotating belt 3 is connected with the flexible closing line 4.

[0082] The flexible closing line 4 is arranged on the closing rotating belt 3, and the closing driving assembly is used to drive the closing rotating belt 3 to rotate along the trajectory of the cover 1, so that the flexible closing line 4 can move together and realize the automatic closing of the garbage bag opening, which not only reduces the number of components of the closing device and reduces the production cost, but also because the closing rotating belt 3 itself has flexibility, it can greatly reduce the processing and assembly accuracy requirements. In addition, the flexible closing line 4 can cover the entire cover 1 when the closing rotating belt 3 rotates along the trajectory of the cover 1, which not only can well close the garbage bag with a wide opening and a large thickness, improve the applicability of the product, but also can reduce the closing errors of the garbage bag.

[0083] At the same time, since the closing rotating belt 3 is soft, it can rotate along the trajectory of the cover 1 of any shape, and make the flexible closing line 4 cover the entire cover 1 and close the garbage bag mouth. Therefore, the shape of the cover 1 is not restricted, which not only provides better design creativity for the appearance of the trash can, but also improves the flexibility of the closing rotating belt 3 and the flexible closing line 4 during work, avoids jamming and loosening problems during work, and ensures that the garbage bag mouth is effectively and evenly closed.

[0084] The cover body 2 is also provided with a sealing device corresponding to the closing device. The sealing device includes a sealing drive component and a hot melt sealing component. The sealing drive component drives the hot melt sealing component to hinge and open and close on the cover 1.

[0085] The sealing drive assembly is used to drive the hot melt sealing assembly to achieve hinged opening and closing, which not only reduces the number of components of the sealing device and reduces production costs, but the hinged cooperation of the hot melt sealing assembly can achieve a wide range of angles within a short range of activity, which not only meets the sealing requirements of garbage bags with wide openings, but also reduces the power consumption of the hot melt sealing assembly during activity, reduces the cost of use, and the hot melt sealing assembly will not vibrate, make abnormal noises, or other problems when hingedly opened and closed, thereby improving the user experience.

[0086] At the same time, the hot melt sealing component adopts a hinged closure method to cover a single side area of ​​the cover 1, and cooperates with the flexible closing line 4 to achieve a full range of flexible side gathering effect on the cover 1, which can effectively avoid the problem of thin hot melt sealing in some parts due to uneven folding position when closing the garbage bag, thereby improving the sealing stability.

This not only effectively reduces the space occupied by the top cover driving assembly, the lid body driving assembly, the closing driving assembly and the sealing driving assembly on the barrel body 40 and the lid body 2, improves the compactness of the coordination between the components, but also reduces the overall weight of the lid body 2.

[0089] A volute fan 41 is disposed inside the barrel body 40 to discharge air toward the bottom thereof.

[0090] The air inside the barrel body 40 is extracted by the volute fan 41, so that a negative pressure state is formed inside the barrel body 40, so that the annular film tube garbage bag can be automatically laid inside the barrel body 40. At the same time, the air extracted by the volute fan 41 is directly discharged to the bottom of the barrel body 40, which not only avoids the problem that the volute fan 41 in the prior art is set on the top of the garbage can, which is easy to tip over when the garbage can is used, so as to improve the stability of the garbage bag. At the same time, since the air is discharged to the bottom of the barrel body 40, there is no need to consider the obstruction of the exhaust port, so that the garbage can can be placed in any position at will to reduce space occupancy. In addition, the volute fan 41 is silent and efficient when working, and can extract the air inside the barrel body 40 in a relatively short time, thereby completing the automatic and rapid laying of the garbage bag to improve the user experience.

[0091] The usage of the above-mentioned smart trash can is as follows:

[0092] The top cover 55 is flipped and opened and closed at the top rear side of the cover body 2 by the driving of the top cover driving assembly, and the cover body 2 is flipped and opened and closed at the top rear side of the barrel body 40 by the driving of the cover driving assembly.

[0093] When the top cover 55 is opened, the user can put garbage into the garbage bag inside the barrel body 40 , replace the annular film tube garbage bag in the bag groove 53 , and take the sealed garbage bag out of the barrel body 40 .

[0094] In the initial state, the hot melt sealing assembly is hinged open and will not block the cover 1, the barrel mouth 50 of the barrel body 40, or the opening of the garbage bag.

[0095] The closing drive assembly works and drives the closing rotary belt 3 to rotate along the trajectory of the cover 1. The closing rotary belt 3 drives the flexible closing line 4 to be pulled out during the rotation. During the entire rotation process of the closing rotary belt 3, the flexible closing line 4 is always in a linear tensioned state and closes the garbage bag opening on the cover 1; when the closing rotary belt 3 rotates to the initial position, the flexible closing line 4 closes the garbage bag opening between the hot-melt sealing assemblies, and the sealing drive assembly works and drives the hot-melt sealing assembly to perform horizontal hinged closure, vertical hinged closure, or inclined hinged closure along the opening of the cover 1. The hot-melt sealing assembly performs hot-melt sealing on the closed garbage bag opening when closing.

[0096] The flexible closing line 4 and the hot-melt sealing assembly realize normal closing and sealing of the garbage bag when the cover 2 is in the closed state, or realize overload closing and sealing of the garbage bag when the cover 2 is in the open state.

[0097] The sealed garbage bag and the annular film tube garbage bag are separated by hot-melt sealing components, separated from each other by flipping open the cover body 2, or manually separated from each other after the cover body 2 is flipped open.

[0098] After the garbage bag is taken out of the barrel body 40, the cover body 2 is flipped and closed, and then the volute fan 41 starts to work and discharges the air inside the barrel body 40 to the bottom of the barrel body 40, so that a negative pressure state is formed inside the barrel body 40. At this time, under the action of atmospheric pressure, the annular membrane tube garbage bag is drawn out from the bag groove 53 and enters the barrel body 40 to complete the automatic paving of the garbage bag.

[0099] As a preferred solution of this embodiment, it may also have the following additional technical features:

The motor drives the closing group 6 to drive the closing rotating belt 3 to rotate along the trajectory of the cover 1 through the closing driving wheel 8 and the plurality of steering wheels 9. The flexible closing line 4 is automatically wound in a straight line when the closing rotating belt 3 rotates, and the opening of the garbage bag is closed to the hot melt sealing component.

[0105] Compared with the prior art where the cover 1 can only be round or square, the cover 1 of this embodiment can be of any shape, and the closing rotating belt 3 can rotate on the track of the cover 2 of any shape through the closing driving wheel 8 and a plurality of steering wheels 9.

[0110] A hot melt block 14 is disposed on the first sealing block 12 and / or the second sealing block 13 .

[0111] That is, the hot melt block 14 can be set separately on the first sealing block 12, or set separately on the second sealing block 13, or set on both the first sealing block 12 and the second sealing block 13. In order to achieve a better hot melt effect, the present embodiment preferably provides hot melt blocks 14 on the inner sides of both the first sealing block 12 and the second sealing block 13.

[0116] A sealing intermediate transmission member 18 is arranged between the motor-driven sealing group 17 and the first sealing block 12 or the second sealing block 13. The sealing intermediate transmission member 18 is a transmission belt or a transmission wheel, and there is meshing transmission or friction transmission between it and the motor-driven sealing group 17, the first sealing block 12 or the second sealing block 13.

[0117] Specifically, the closing driving wheel 8 and the steering wheel 9 are gears, and a transmission gear 10 is fixedly arranged on the closing driving wheel 8. The closing intermediate transmission member 7 is a toothed belt, and the inner side of one end thereof is meshed with the motor-driven closing group 6 through the teeth for transmission, and the inner side of the other end is meshed with the transmission gear 10 for transmission through the teeth. The closing rotary belt 3 is a toothed belt and is wound around the closing driving wheel 8 and the outer periphery of several steering wheels 9 along the trajectory of the cover 1. The inner side of the closing rotary belt 3 is meshed with the closing driving wheel 8 and several steering wheels 9 through the teeth for transmission. A connecting block 11 is fixedly arranged on the outer side of the closing rotary belt 3, and the connecting block 11 is fixedly connected to the flexible closing line 4.

[0118] Since the connecting block 11 is fixed to the outside of the closing rotating belt 3 and is fixedly connected to the flexible closing line 4, the connecting block 11 will not collide with other components when the closing rotating belt 3 rotates, and will not cause obstruction of the cover 1, the barrel opening 50, and the garbage bag opening.

[0119] One end of the first sealing block 12 is rotatably mounted on the cover body 2 and has a first tooth portion 20 disposed on its periphery.

[0129] The working principle of closing and sealing the garbage belt is as follows Figure 25-Figure 30 As shown:

[0130] In the initial state, the first sealing block 12 and the second sealing block 13 are hinged open, and will not block the lid 1, the barrel opening 50, and the opening of the garbage bag, so that users can put garbage in. At the same time, the connecting block 11 is located above the first sealing block 12 and the second sealing block 13. Fig.25 shown.

[0131] The motor drives the closing group 6 to start working, and drives the closing driving wheel 8 to rotate on the cover body 2 through the closing intermediate transmission member 7. When the closing driving wheel 8 rotates, it drives the closing rotary belt 3 to rotate along the track of the cover 1 through a number of steering wheels 9. When the closing rotary belt 3 rotates, it drives the connecting block 11 to follow the movement, and at the same time drives the flexible closing line 4 to be pulled out from the winding box 5; during the entire rotation process of the closing rotary belt 3, the flexible closing line 4 is always in a linear tension state under the automatic winding force of the winding box 5, and closes the garbage bag opening on the cover 1. Its state change process is as follows: Figure 26-Figure 28 shown.

[0132] When the closing rotating belt 3 rotates to the initial position, the connecting block 11 is reset accordingly, and at the same time, the flexible closing line 4 closes the opening of the garbage bag to between the first sealing pressing block 12 and the second sealing pressing block 13. Fig.29 shown.

[0133] The motor drives the sealing group 17 to start working, and drives the first sealing block 12 to rotate on the cover body 2 through the sealing intermediate transmission member 18. The first sealing block 12 drives the second sealing block 13 to hinge and close while rotating. When the first sealing block 12 and the second sealing block 13 are hinged and closed, they use the hot melt block 14 to heat-seal the folded garbage bag mouth. Fig.30 shown.
