Description

Technical Field

[0001] This utility model relates to the field of trash can technology, and in particular to intelligent trash cans. Background Technology

[0002] Currently, trash cans, as widely used waste collection devices in daily life and public environments, typically have a hollow interior and an open top, with a lid that can be opened or closed. Users must manually open the lid before disposing of trash into the can. While this traditional design is simple and easy to manufacture, it presents numerous inconveniences and drawbacks in practical use.

[0003] This type of trash can is cumbersome to operate, especially when users are holding trash in both hands, or when the trash is heavy or bulky. They need to free one hand to open the lid before disposing of the trash, resulting in low efficiency and a poor user experience. Furthermore, in frequently used public places such as restaurants, train stations, and hospitals, manually opening the lid is not only time-consuming but also prone to causing trash leakage and inaccurate disposal. Utility Model Content

[0004] Therefore, it is necessary to address the problem that trash cans require opening the lid to throw away trash, which is cumbersome. A smart trash can is needed that can automatically open the trash bag inside the can. The trash bag is normally clamped near the opening, but when trash is detected being thrown in, the trash bag is automatically released, allowing the trash to fall into the bag automatically, eliminating the need for a lid or opening operation.

[0005] A smart trash can includes:

[0006] The main body unit is hollow inside and open at the top, and one side of the main body unit has an outlet that communicates with the interior;

[0007] A detection unit is located on the opening of the main body unit and is used to identify whether there is an object being inserted.

[0008] A storage unit is located on one side of the main unit, and the storage unit stores multiple garbage bags inside;

[0009] A bag opening unit is provided inside the main body unit, and the bag opening unit is capable of pulling out and opening the garbage bag inside the storage unit;

[0010] A clamping unit is disposed within the main body unit, and the clamping unit is capable of clamping or releasing the garbage bag near the bag opening; and

[0011] The control unit is located on the main body unit, and the control unit is electrically connected to the detection unit, the bag opening unit and the clamping unit.

[0012] The aforementioned smart trash can features a folded trash bag housed within a storage unit. A bag-opening unit pulls the bag open, creating a sealed opening. In its normal state, a clamping unit holds the bag closed near the opening. When trash is deposited into the top opening of the main unit, a detection unit detects this and sends a signal to the control unit, which then controls the clamping unit to release the bag. Since the bag opening is initially open, the trash falls directly into the bag. When the detection unit detects no further trash being deposited, it sends a signal to the control unit, which then controls the clamping unit to close the bag, preventing trash exposure and odor. This smart trash can eliminates the need for a lid or opening mechanism; users can simply deposit trash, making it more convenient and hygienic.

[0013] In one embodiment, the detection unit includes an infrared emitter and an infrared receiver disposed at a relative interval on the opening of the main unit. The infrared emitter and the infrared receiver are electrically connected to the control unit. Under normal conditions, the infrared light emitted by the infrared emitter is received by the infrared receiver. When garbage is thrown in, the infrared light emitted by the infrared emitter to the infrared receiver is interrupted, and the control unit starts to control the clamping unit to release the garbage bag.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0045] Please see Figures 1 to 4 In one embodiment, a smart trash can 100 includes: a main body unit 1, a detection unit 2, a storage unit 3, a bag opening unit 4, a clamping unit 5, and a control unit. The main body unit 1 is hollow inside with an opening 11 at the top, and has an outlet 12 communicating with the interior on its front side. The detection unit 2 is located on the opening 11 of the main body unit 1 and is used to identify whether any items have been placed inside. The storage unit 3 is located on the top front side of the main body unit 1, above the outlet 12, and stores multiple trash bags 200 inside. The bag opening unit 4 is located inside the main body unit 1 and can pull out and open the trash bags 200 in the storage unit 3. The clamping unit 5 is located inside the main body unit 1 and can clamp or release the trash bags 200 near the bag opening. The control unit is located on the main body unit 1 and is electrically connected to the detection unit 2, the bag opening unit 4, and the clamping unit 5.

[0046] The aforementioned smart trash can 100 has a folded trash bag 200 housed within a storage unit 3. A bag opening unit 4 can pull open the trash bag 200 within the storage unit 3, opening its mouth. In its normal state, the clamping unit 5 clamps the trash bag 200 near the opening, keeping it closed. When trash is thrown into the top opening 11 of the main unit 1, it is detected by the detection unit 2, which transmits a signal to the control unit, causing the control unit to control the clamping unit 5 to release the trash bag 200. Since the trash bag 200's mouth is initially open, the trash falls directly into the bag. When the detection unit 2 detects no more trash being thrown in, it transmits a signal to the control unit, causing the control unit to control the clamping unit 5 to close the trash bag 200, preventing trash exposure and odor pollution. This smart trash can 100 eliminates the need for a lid and opening mechanism; the user can directly throw in trash, making operation more convenient and hygienic.

[0047] The main unit 1 includes a rectangular shell 13, with a garbage inlet at the top of the shell 13, a storage unit 3 at the upper front side, and an outlet 12 for garbage bags 200 at the lower front side.

[0048] The detection unit 2 can be an infrared beam sensor, a ToF ranging sensor, a capacitive proximity sensor, a camera recognition unit, etc.

[0049] Please see Figure 1 and Figure 3 In one embodiment, the detection unit 2 uses an infrared beam sensor to perform detection. Specifically, the detection unit 2 includes an infrared emitter 21 and an infrared receiver 22 that are spaced apart from each other on the opening 11 of the main unit 1 in the left-right direction. The infrared emitter 21 and the infrared receiver 22 are electrically connected to the control unit.

[0050] Under normal conditions, the infrared rays emitted by the infrared transmitter 21 are received by the infrared receiver 22, and it is determined that no garbage is being disposed of. When garbage is thrown in, the infrared rays emitted by the infrared transmitter 21 to the infrared receiver 22 are blocked, and the control unit activates the control clamping unit 5 to release the garbage bag 200, so that the garbage can fall into the garbage bag 200.

[0051] The infrared emitter 21 consists of an emitting LED and a focusing tube, while the infrared receiver 22 consists of a receiving LED and a focusing tube. One emitting LED and one receiving LED form a pair of infrared LEDs, which are positioned opposite each other on the same straight line. The emitting LED emits infrared light, which is received by the receiving LED, thus forming a complete infrared beam. The detection unit 2 includes multiple pairs of infrared LEDs; when one or more infrared beams are blocked, a signal is output.

[0052] The focusing tube is fitted over the emitting and receiving LED beads. Its length is greater than that of the LED beads. Its function is to reduce the fan-shaped angle of the infrared light emitted by the emitting LED beads and the fan-shaped angle of the light received by the receiving LED beads, so that the two adjacent infrared beams will not interfere with each other.

[0053] Please see Figures 2 to 5 In one embodiment, the storage unit 3 includes a box body 31 and hanging ears 32. The box body 31 has a storage compartment 33 for storing garbage bags 200. Multiple garbage bags 200 are folded in half from both sides along the width direction to the middle, forming a four-layer folded state, and stored in the storage compartment 33. The hanging ears 32 protrude from the inner side of the box body 31, and the garbage bags 200 have hanging holes 201, which are fitted onto the hanging ears 32.

[0054] The hanging ear 32 includes a hanging platform 321 and a separating platform 322. The hanging platform 321 protrudes from the box body 31, and the separating platform 322 is located on the outer side of the hanging platform 321. The vertical cross-sectional area of ​​the separating platform 322 gradually decreases from the end furthest from the box body 31 to the other end. The separating platform 322 is triangular in shape when viewed from the side and can be integrally formed with the hanging platform 321. The separating platform 322 is used to separate the first to fourth layers of the garbage bag 200. Because after the garbage bag 200 is flattened, the first to fourth layers are stuck together and are relatively difficult to separate.

[0055] The principle of separation platform 322: The garbage bag 200 is made of plastic and is very thin, making it easy to deform. The first layer of the garbage bag 200 is gradually pulled from the bottom to the top of the separation platform 322 until it detaches from the separation platform 322. At this time, the second layer is not yet under tension and remains on the hanging platform 321 until the sides of the first and second layers are straightened. The second layer then begins to be under force and detaches from the separation platform 322. Then the third and fourth layers are detached from the separation platform 322 in turn.

[0056] The box 31 can be magnetically attached to the upper front side of the outer shell 13. Specifically, four mounting magnets 18 are fixedly provided on the upper front side of the outer shell 13, and four mounting iron pieces 34 are fixedly provided on the inner side of the box 31. The positions of the mounting magnets 18 and the mounting iron pieces 34 correspond one-to-one. Through the magnetic attraction between the four mounting iron pieces 34 and the four mounting magnets 18, the box 31 can be easily inserted, removed, and fixed to the upper front side of the outer shell 13.

[0057] Please see Figure 3 , Figure 6 and Figure 7 In one embodiment of the bag opening unit 4, a first rack 61 and a first slide rod 62 extend along the front-rear direction inside the main body unit 1. The bag opening unit 4 includes a push rod body 41, a first motor 42, a first output gear 43, a first transmission gear 44, a first transmission shaft 45, and a push rod main suction component 46. The push rod body 41 is slidably connected to the first slide rod 62. The first motor 42 is mounted on the push rod body 41. The first output gear 43 is mounted on the output end of the first motor 42. The first transmission gear 44 meshes with the first output gear 43 and the first rack 61 respectively. The end of the first transmission shaft 45 is fixedly connected to the first transmission gear 44, and the first transmission shaft 45 is rotatably mounted on the push rod body 41. The push rod main suction component 46 is mounted on the front side of the push rod body 41. The outer surface of the garbage bag 200 is provided with a secondary suction component 202 that magnetically attracts the push rod main suction component 46. Of course, the push rod body 41 can also be driven by other methods, such as belt drive, screw drive, etc.

[0058] The first motor 42 drives the first output gear 43 to rotate, which in turn causes the first transmission gear 44 to drive the first transmission shaft 45 to rotate. The first transmission gear 44 moves along the first rack 61, ultimately causing the push rod body 41 to move closer to or further away from the storage unit 3. When the push rod body 41 approaches the storage unit 3, the main suction component 46 of the push rod adheres to the auxiliary suction component 202, and the push rod body 41 moves away from the storage unit 3 under the drive of the first motor 42, pulling the garbage bag 200 open layer by layer.

[0059] To ensure more stable operation, two first motors 42, first output gear 43, and first transmission gear 44 can be provided. The two first motors 42 are respectively located at both ends of the push rod body 41 to provide power to the push rod body 41.

[0060] The main suction component 46 of the push rod can be a magnet, and the secondary suction component 202 can be an iron sheet. The iron sheet is attached to the outer surface of each garbage bag 200 using double-sided adhesive. The thickness of the double-sided adhesive must be ≥0.5mm to isolate the magnetic attraction of the magnet on the push rod body 41 to other garbage bags 200. When the magnet on the push rod body 41 attracts the outermost garbage bag 200, it can prevent the simultaneous attraction of the iron sheets on adjacent garbage bags 200. There can be two magnets, and the center of the magnet and the center of the iron sheet on the garbage bag 200 are on the same straight line.

[0061] The push rod body 41 is equipped with linear bearings at both ends, and two first slide rods 62 are spaced apart along the left and right direction. The entire push rod body 41 is fitted onto the first slide rods 62 through the linear bearings, ensuring more stable and smooth linear movement of the push rod unit. A notch 411 is provided at the bottom middle of the push rod body 41. This notch 411 is designed to prevent the garbage bag 200 from getting stuck in the gap between the push rod body 41 and the clamping unit 5 when the garbage bag 200 is pushed forward.

[0062] Please see Figure 3 , Figure 7 and Figure 8 In another embodiment, the smart trash can 100 also includes a pressing edge 63 and a hanging assembly 64. The top of the push rod body 41 has a mounting hole 412, and the top of the mounting hole 412 has a slot 413 with a width smaller than the diameter of the mounting hole 412. The hanging assembly 64 includes a hanging rod 641, a blade 642, and a hanging head 643. The rear end of the hanging rod 641 passes through the mounting hole 412 and connects to the main body unit 1, while the front end of the hanging rod 641 passes through the trash bag 200 and the hanging platform 321 of the box body 31. The hanging head 643 protrudes from the top of the front end of the hanging rod 641 and is elongated, allowing passage through the slot 413. The blade 642 is located within the hanging head 643 and protrudes from the end of the hanging head 643 away from the box body 31. The pressing edge 63 is located at the top of the main body unit 1 and close to the blade 642, extending downwards and beyond the top surface of the hanging head 643.

[0063] When the garbage bag 200 is full, the push rod body 41 will push the garbage bag 200 closer to the box body 31. The pressing table 63 will press the top of the garbage bag 200 down to the blade 642. With the push rod body 41 pushing further, the blade 642 will cut off the top of the garbage bag 200, making it unable to continue hanging on the hanging rod 641, and it will fall to the bottom of the outer shell 13 and be pulled out by the outlet 12.

[0064] Furthermore, the top surface of the outer casing 13 contains two pressing platforms 63, which are triangular when viewed from the side. The pressing platforms 63 are located on the upper part of the hanging rod 641, with a certain gap between them for the upper part of the hanging hole 201 on the garbage bag 200 to pass through. The upper part of the mounting hole 412 of the push rod body 41 has an open slot 413, and the pressing platforms 63 extend into the upper part of the mounting hole 412.

[0065] Please see Figure 2 , Figure 3 , Figure 9 and Figure 10 In one embodiment, the main body unit 1 is provided with a second rack 65 and a second slide bar 66 extending in the left-right direction, and the clamping unit 5 includes a first clamping group 51 and a second clamping group 52.

[0066] The first clamping assembly 51 includes a first clamping rod body 511, a second motor 512, a second output gear 513, a second transmission gear 514, and a second transmission shaft 515. The first clamping rod body 511 is slidably connected to the second slide rod 66. The second motor 512 is mounted on the first clamping rod body 511. The second output gear 513 is mounted on the output end of the second motor 512. The second transmission gear 514 meshes with the second output gear 513 and the second rack 65, respectively. The end of the second transmission shaft 515 is fixedly connected to the second transmission gear 514, and the second transmission shaft 515 is rotatably mounted on the first clamping rod body 511.

[0067] The second clamping assembly 52 includes a second clamping rod body 521, a third motor, a third output gear, a third transmission gear 522, and a third transmission shaft. The second clamping rod body 521 is slidably connected to the second slide rod 66 and is spaced apart from the first clamping rod body 511 in the left-right direction. The third motor is mounted on the second clamping rod body 521, and the third output gear is mounted on the output end of the third motor. The third transmission gear 522 meshes with the third output gear and the second rack 65 respectively. The end of the third transmission shaft is fixedly connected to the third transmission gear 522, and the third transmission shaft is rotatably mounted on the second clamping rod body 521.

[0068] Please see Figure 9 and Figure 10Driven by the second motor 512 and the third motor, the first clamping rod body 511 and the second clamping rod body 521 can move towards each other and clamp the bag opening (neck of the garbage bag 200) near the garbage bag 200, and the first clamping rod body 511 and the second clamping rod body 521 can move in opposite directions and release the bag opening near the garbage bag 200, so that the garbage can fall into the garbage bag 200.

[0069] Of course, the driving of the first clamping rod body 511 and the second clamping rod body 521 can also be in other ways, such as belt drive, screw drive, etc.

[0070] To ensure more stable drive, two sets of the second motor 512, second output gear 513, and second transmission gear 514 can be provided. The two second motors 512 are respectively located at both ends of the first clamping rod body 511, and the two second transmission gears 514 are respectively fixed at opposite ends of the second transmission shaft 515. Linear bearings are also provided at both ends of the first clamping rod body 511. Two second racks 65 and two second slide rods 66 are each provided, with the linear bearings slidingly connected to the second slide rods 66 in a one-to-one correspondence. It is understood that the third motor, third output gear, and third transmission gear 522 can also adopt the aforementioned structure.

[0071] In another embodiment, the smart trash can 100 further includes a clamp unit 7 detachably mounted on the first clamp body 511 or the second clamp body 521. The bag opening unit 4 includes a push head 47 extending downward from the bottom of the push rod body 41.

[0073] The first clamping rod body 511 and the second clamping rod body 521 move towards each other and move closer together, causing the first track 516 and the second track 523 to close together to form a clamp channel 53. The discharge port 711 of the clamp storage box 71 and the clamp channel 53 are on the same plane. The push head 47 can push the top clamp 73 out of the discharge port 711 and make the clamp 73 clamp the opened garbage bag 200 near the bag opening along the clamp channel 53. The push head 47 can be a metal strip to ensure that it will not deform when pushing the clamp 73.

[0074] In one embodiment, a storage box frame 517 is provided on the outer side of the first clamping rod body 511 away from the box body. The clamp storage box 71 is installed in the storage box frame 517 of the first clamping rod body 511. The clamp storage box 71 can only be loaded and unloaded from the side and cannot move in other directions. Furthermore, an iron sheet is attached to the side of the clamp storage box 71, and a magnet is attached inside the storage box frame 517. The iron sheet of the clamp storage box 71 will be attracted to the magnet, thereby ensuring that the clamp storage box 71 is easy to load and unload and is not easy to fall off.

[0075] In one embodiment, the elastic top assembly 72 includes a screw 721, a spring 722, and a top plate 723. The clip storage box 71 has two hollow guide posts 74. The top plate 723 is fitted onto the two guide posts 74, and the spring 722 is also fitted onto the guide posts 74 and abuts against the top plate 723. The screw 721 is locked to the bottom end of the guide posts 74, and the screw cap presses against the spring 722. Under the elastic force of the spring 722, the top plate 723 pushes multiple clips 73 upwards, so that the topmost clip 73 is positioned precisely at the discharge port 711.

[0076] Clips 73 can be loaded into clip storage box 71 through discharge port 711. Clip storage box 71 stores multiple stacked clips 73 simultaneously. When clips 73 are used up, top plate 723 abuts against baffle 712 of clip storage box 71, positioned on the plane of discharge port 711. Top plate 723 will block pusher head 47 from moving forward, as top plate 723 can only move up and down along guide post 74. Pusher head 47 channel is provided at the top of clip storage box 71, running through the front and back of clip storage box 71. Pusher head 47 can push the topmost clip 73 forward into clip channel 53.

[0077] Please see Figure 1 and Figure 14In another embodiment, the intelligent trash can 100 further includes a conveying unit 8 located at the bottom inner side of the outer casing 13. The conveying unit 8 includes a conveying motor 81, a fourth output gear 82, a fourth transmission gear 83, a fourth transmission shaft 84, a conveyor belt 85, and a rotating shaft 86. The fourth output gear 82 is located at the output end of the conveying motor 81. The fourth transmission gear 83 meshes with the fourth output gear 82. The end of the fourth transmission shaft 84 is fixedly connected to the fourth transmission gear 83. The rotating shaft 86 is spaced apart from the fourth transmission shaft 84 in the front-back direction and is rotatably located at the bottom inner side of the outer casing 13. The conveyor belt 85 is respectively sleeved on the rotating shaft 86 and the fourth transmission shaft 84. There are two rotating shafts 86, located in the middle and front of the conveyor belt 85, respectively. When the conveyor belt transports heavy objects, the middle rotating shaft 86 plays the role of supporting the conveyor belt. After the garbage bag 200 containing garbage is cut by the blade 642, it falls onto the conveyor belt 85. The conveyor belt 85 can move back and forth with the garbage bag 200 to shake the garbage bag 200, making it easier for the garbage to fall into the garbage bag 200. It can also transport the garbage bag 200 out of the garbage can through the outlet 12.

[0078] Please see Figure 1 and Figure 3 Furthermore, the smart trash can 100 also includes a laser rangefinder 300, which is fixed on the outer shell 13 and faces the inside of the trash bag 200. When it detects that trash is approaching the clamping area of ​​the trash bag 200, it drives the conveyor belt to move back and forth, so that the trash bag 200 will shake back and forth. In this way, if any trash is stuck in the upper part of the trash bag 200, it will be completely shaken into the trash bag 200.

[0079] If the trash is still detected after the laser rangefinder 300 performs the above operations, it indicates that the bag is nearly full, and the trash can will automatically pack it up. At this time, the push rod body 41 is at the rear of the trash can, and the first clamping rod body 511 and the second clamping rod body 521 are on the left and right sides of the inner wall of the trash can. Driving the first clamping rod body 511 and the second clamping rod body 521 to move towards each other, the second rack 65 has a stop 67 in the middle. The first clamping rod body 511 and the second clamping rod body 521 move towards each other until they are stopped by the stop 67. At this time, the first clamping rod body 511 and the second clamping rod body 521 are completely pressed together, clamping the trash bag 200. The clamped part of the trash bag 200 is in a thin strip state, which makes it easy to push into the inside of the clamp 73.

[0080] Please see Figure 15 and Figure 16In another embodiment, the smart trash can 100 also includes a water supply unit 9 disposed within the outer casing 13. A water storage tank 14 is located at the bottom of the outer casing 13. The water supply unit 9 includes a water pump 91, an inlet pipe 92, an outlet pipe 93, and a nozzle 94. One end of the inlet pipe 92 is connected to the water storage tank 14, and the other end is connected to the inlet of the water pump 91. One end of the outlet pipe 93 is connected to the outlet of the water pump 91, and the other end is connected to the nozzle 94. The nozzle 94 has an adjustable angle and is located near the opening 11 of the outer casing 13. The water pump 91 provides the power for water spraying. The outlet of the nozzle 94 determines the shape of the water jet. The shape of the sprayed water jet conforms to the inner wall of the trash bag 200. The liquid sprayed from the nozzle 94 carries a certain pressure, which can thus open the trash bag under the nozzle 94.

[0081] Furthermore, the top of the water storage tank 14 is provided with a water inlet 15, and the water storage tank 14 extends along its height with a water level observation window 16. Inside the water level observation window 16 is a brightly colored water level float 17, allowing for easy observation of the water level. Users can add a certain amount of disinfectant or perfume to the water storage tank 14. The solution, after mixing with water, is sprayed through the water delivery unit 9 into the garbage bag 200 to achieve disinfection and deodorization.
