Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent trash cans, and in particular relates to a trash can structure with automatic trash bag packaging. Background Art

[0002] At present, smart home products are constantly improving people's quality of life, and smart trash cans are one of them. Trash cans are a household product that people often use in their daily lives. As people pursue higher and higher quality home environments, they have gradually evolved from simple trash cans to modern smart trash cans.

[0003] For example, the Chinese invention patent document with authorization publication number CN109319332B discloses an automatically sealed trash can, comprising a trash can main body, a trash bag storage device provided above the trash can main body, a trash bag feeding device and a trash bag sealing device provided below the trash bag storage device, the trash bag feeding device and the trash bag sealing device being controlled by a control circuit, the control circuit being connected to a power supply, the trash bag feeding device comprising a first and a second bag feeding roller which are arranged relatively and can move relative to each other, a bag feeding roller driving mechanism being connected to the first and the second bag feeding rollers, the trash bag sealing device comprising a first slide and a second slide which are arranged relatively and can move relative to each other, a trash bag sealing member being provided on the first slide or the second slide, the trash bag sealing member being located on the end surface where the first slide and the second slide are connected. The relative arrangement means the first and second rollers are located on the left and right sides, respectively. When the garbage bags are to be loaded, the first and second rollers move from opposite sides toward the center. Once the two rollers make contact, the friction between the rollers and the plastic film of the bag material propels the bag material into the trash can body, allowing it to be loaded. Once loaded, the two rollers can then move from the center toward the sides in opposite directions before returning to their initial positions. The garbage bag sealing element consists of a round electric heating wire with a flat electric heating wire attached to one or both sides. This allows for multiple sealing and cutting operations, ensuring a more reliable seal.

[0004] The technical solution in the aforementioned patent document utilizes a first slide and a second slide that move together to clamp the garbage bag film. The flat wire on the second slide heat-seals the film, while the round wire cuts the bag. This creates a smooth seal at the bottom and top of the garbage bag. However, the seal at the bottom of the garbage bag is formed by fusing the two layers of film together to form a straight line. Due to the low mechanical strength of the garbage bag film, cracking is easily caused at the seal.

[0005] To overcome the technical deficiencies of the aforementioned patent document, the Chinese invention patent document with authorization publication number CN111977218B discloses a flexible packaging mechanism for garbage bags and a garbage can, comprising a mounting plate, a driving device disposed on the mounting plate, a closing mechanism, and a sealing device, wherein: the mounting plate is provided with a mounting plate through-hole for the garbage bags and garbage to pass through, a flexible belt limiting groove is provided on the mounting plate around the mounting plate through-hole, the driving device includes a motor and a reduction transmission gear driven by the motor, the sealing device is fixedly disposed at a position on one side of the mounting plate through-hole for sealing the closed garbage bags; the closing mechanism includes a flexible belt disposed around the mounting plate through-hole, the head end of the flexible belt being fixed to the mounting plate, the middle portion of the flexible belt passing around the sealing end face of the sealing device and meshing with the reduction transmission gear, and the end portion reciprocatingly moving along the flexible belt limiting groove as the reduction transmission gear rotates, so that the rotation of the reduction transmission gear can drive the flexible belt to tighten or reset around the sealing device; the flexible belt has high-temperature resistant insulation properties at least at the portion in contact with the sealing end face, and the driving device and the sealing device are communicatively connected to the control device. A flexible belt is used for closing, and the flexible belt is meshed with the reduction transmission gear device of the driving device. Under the driving action of the driving device and the guiding and limiting action of the flexible belt limit groove, the garbage bag can be effectively gathered to the sealing end surface, and cooperate with the sealing device to realize the packaging and sealing operation. Compared with the existing flexible packaging mechanism for garbage bags with rigid pressure rod packaging and sealing, the flexible packaging mechanism for garbage bags of the present invention has fewer structural parts, which greatly reduces the processing and assembly accuracy requirements for each spare part, reduces production and assembly costs, and has a simplified structure, a low failure rate, and better reliability. At the same time, when the amount of garbage in the garbage bag exceeds the closing plane, the flexible packaging mechanism for garbage bags of the present invention can still achieve good sealing and packaging while ensuring the quality of sealing and packaging.

[0006] It can be seen that the technical solution of the above patent document is to use a flexible belt to gather the garbage bag film on the positioning block, and the heating wire on the positioning block heat-seals and cuts the garbage bag at the same time. The heat seal is completed after the heat seal is gathered, which can increase the strength of the seal, and a gathered heat seal is formed at the top and bottom of the garbage bag, thereby forming a hand-held position for picking up. However, in the patent document CN111977218B, when the garbage bag is pulled onto the positioning block by the flexible belt, there is a corner at the contact position of the flexible belt and the positioning block, and the corner position cannot make the flexible belt and the positioning block completely fit. When the garbage belt is pulled to the corner or the back of the positioning block, it will cause the position to be unable to be heat-sealed, which will lead to leakage. Summary of the Invention

[0036] In one embodiment of the garbage bin structure for automatically packing garbage bags of the present invention, please refer to Figures 1 to 8 , a trash can with automatic garbage bag packaging can realize automatic transportation and heat-sealing packaging of garbage bags, realize intelligence, and meet the needs of the market and users. Specifically, the trash can includes a barrel body 100, an upper shell 200 and a heat-sealing device 300. Among them, a accommodating chamber 101 is provided in the barrel body 100, and the upper shell 200 is provided at the top of the barrel body 100, and covers the accommodating chamber 101. An installation chamber 210 and a heat-sealing chamber 220 are provided in the upper shell 200, and the installation chamber 210 is used to store the garbage bag film roll to be heat-sealed. An input port 211 is provided on the top side of the installation chamber 210, and garbage can be put into the garbage bag in the trash can from the input port 211. An airtight opening 212 is provided on the bottom side so that the garbage bag can be inserted into the accommodating chamber 101.

[0037] Please refer to Figure 4 and Figure 5The heat sealing device 300 is arranged in the heat sealing chamber 220 and is used to heat seal the bottom and mouth of the garbage bag film and cut and pack the garbage bags. Specifically, the heat sealing device 300 includes a pad 310, a clamping plate 320, a belt 330, a drive mechanism 340 and an electric heating element. The pad 310 and the drive mechanism 340 are installed in the heat sealing chamber 220, and one end of the clamping plate 320 is pivotally connected to the pad 310, and between the clamping plate 320 and the pad 310. Specifically, a connection position is provided on the pad 310, and the clamping plate 320 and the connection position are connected by a pivot, so that the clamping plate 320 can rotate around the pivot. One end of the belt 330 is connected to the clamping plate 320, and the other end is connected to the drive mechanism 340, so that the belt 330, the clamping plate 320 and the pad 310 form a telescopic structure. The electric heating element is arranged on the inner side of the pad 310 or the clamping plate 320. Preferably, the electric heating element is arranged on the pad 310, so that it is more convenient to connect the electric heating element to electricity. Specifically, the electric heating element includes a heat-sealing heating element 350 and a heating wire 360. Preferably, the heat-sealing heating element 350 is in two groups, one of which is used for packaging and sealing the garbage bag, and the other group of heat-sealing heating elements 300 is used for heat sealing the bottom of the next garbage bag. Specifically, the two heat-sealing heating elements 350 and the heating wire 360 are arranged on the inner side of the pad 310 or the splint 320, and the heating wire 360 is located between the two heat-sealing heating elements 350. Among them, the heat-sealing heating element 350 adopts an electric heating block, or uses a heating wire wrapped on a carrier of a flat heat-insulating material, so as to ensure the heating surface and increase the heat-sealing area.

[0038] In the garbage bin structure for automatic packaging of garbage bags of this embodiment, the garbage bag films that are orderly stored can be loaded into the installation cavity 210, and the free ends of the garbage bag films are heat-sealed and extended into the accommodating cavity 101. When the garbage bags are heat-sealed and packaged, the driving mechanism 340 drives the reel 330 to contract. During the contraction process, the reel 330 gathers the garbage bags and pushes them between the clamping plate 320 and the pad 310. When the driving mechanism 340 continues to drive the reel 330, the clamping plate 320 and the pad 310 clamp and press the garbage bags. The electric heating wire 360 can cut the garbage bags, and under the action of the two heat-sealing heating elements 300, the cut garbage bags are heated and fused to achieve the sealing effect. At the same time, the bottom of the next garbage bag that needs to be filled with garbage is sealed, forming a sealed bottom of the garbage bag. The heat-sealed seal after being folded can form a hand-held position, which is convenient for picking up garbage bags. By setting the heat sealing and cutting to be performed by two different components, the length from the heat sealing position to the cutting position can be increased, thereby increasing the hand-held position, making it more convenient to take the packaged garbage bags out of the accommodating chamber 101. Since the drive mechanism 340 is used to drive the roll belt, the roll belt 330 pulls the clamping plate 320 and the pad 310 to clamp the garbage bag, thereby ensuring that sufficient heat sealing pressure is applied to the garbage bag, so that the seal of the garbage bag can be completely heat-sealed, avoiding leakage problems. In addition, the cutting and heat sealing are implemented separately using two independent structures, so as to avoid the seal being located at the cutting position, which can further increase the stability after cutting and heat sealing.

[0039] Further, refer to Figures 1 to 3 A cover plate 201 is rotatably connected to the top side of the upper shell 200 , and the input port 211 is closed by the cover plate 201 . When garbage needs to be put in, the cover plate 201 can be opened.

[0040] For further information, please refer to Figure 3 The cover panels 201 are arranged in two symmetrical groups and are electrically operated for opening and closing. Specifically, the cover panels 201 are each provided with a rotating shaft 202, which is rotatably connected to the upper housing 200. The ends of the rotating shaft 202 are provided with a transmission gear 203. A transmission shaft 204 is located within the upper housing 200. Disc gears 205 are provided at both ends of the transmission shaft 204, and the disc gears 205 mesh with the corresponding transmission gears 203. The transmission shaft 204 is connected to a drive motor 206. Therefore, the drive motor 206 can be used to open and close the two cover panels 201.

[0041] Furthermore, the upper shell 200 can be pivotally connected to the barrel body 100, so that the barrel body 100 can be opened through the connection position between the upper shell 200 and the barrel body 100, and the garbage bag containing the garbage can be taken out.

[0042] Furthermore, an electric heating element is provided on the backing plate 310, and a soft pad 370 is provided on the inner side of the clamping plate 320 to support the electric heating element in clamping the garbage bag. Specifically, when the clamping plate 320 and the backing plate 310 clamp the garbage bag, the soft pad 370 provides flexible support for the garbage bag, making it easier to cut and heat-seal the garbage bag. Furthermore, a support pad 380 is provided on the soft pad 370. The support pad 380 cooperates with the heating wire 360 to further help the heating wire 360 cut the garbage bag. Alternatively, the support pad can be provided on the backing plate 310, and the heating wire 360 can be provided on the support pad, thereby increasing the height of the heating wire 360, thereby helping the heating wire 360 cut the garbage bag.

[0043] Going further, refer to Figure 6 and Figure 7 Two tape rolls 330 are provided, one on each side of the clamping plate 320. In this embodiment, the two tape rolls 330 apply tension to the clamping plate 320, thereby increasing the stability of the force applied to the clamping plate 320 and ensuring the heat-sealing stability of the garbage bag. Furthermore, when the two tape rolls 330 are wound together, the area of the garbage bag requiring heat sealing and cutting is positioned between the two tape rolls 330. This positioning of the two tape rolls 330 in the area requiring heat sealing and cutting prevents deviation of the cutting and heat-sealing areas of the garbage bag.

[0044] Furthermore, refer to Figure 6 and Figure 7 The garbage bin structure for automatic packaging of garbage bags is also provided with a steering structure. One end of the roll 330 passes through the steering structure and is connected to the drive mechanism 340. The steering structure is used to limit the roll 330 to one side of the heat-sealing area formed by the electric heating element. As a result, when the roll 330 gathers the garbage bag, the gathered garbage bag can be completely located in the heat-sealing area. Furthermore, the steering structure is provided in the guide hole 311 on the pad, and the guide hole 311 is located on one side of the heat-sealing area formed by the electric heating element. Specifically, one end of the roll 330 passes through the guide hole 311 and is connected to the drive mechanism 340. The steering position of the roll 330 is completely located on one side of the length direction of the heat-sealing heating element 350. In this embodiment, when the drive mechanism 340 pulls the roll 330, the roll 330 can completely collect the garbage bag onto the heat-sealing heating element 350, avoiding the phenomenon of the garbage bag being leaked and providing heat-sealing stability. More preferably, a guide member is provided in the guide hole 311 to guide the tape 330 to avoid wear and tear of the tape 330. In addition, the steering structure is also provided as a steering shaft provided in the heat sealing cavity 220, or directly as a driving mechanism 340.

[0045] Further, refer to Figures 4 to 7The driving mechanism 340 includes a motor 341 and a traction wheel 342 . The motor 341 is disposed in the heat sealing chamber 220 . The traction wheel 342 is connected to the motor 341 . The winding belt 330 is connected to the traction wheel 342 .

[0046] Furthermore, a specific embodiment of the traction wheel 342 is described. Specifically, the traction wheel 342 is connected to a gear of the motor 341. A stopper 343 is provided on one side of the gear, and a gap is formed between the stopper 343 and the gear. The belt 330 is a toothed belt that passes through the gap and meshes with the gear. More specifically, a bracket 390 is provided on one side of the backing plate 310. The bracket 390 is provided with a reduction gearbox, and the reduction gearbox has two output shafts, each of which is equipped with gears. The motor 341 is connected to the input end of the reduction gearbox. Both gears are connected to the belt 330. In this embodiment, the motor 341 drives the two gears to rotate synchronously through the reduction gearbox, driving the belt 330 to pull the clamping plate 320 and clamp the backing plate 310.

[0047] Furthermore, another embodiment of the traction wheel 342, specifically; the traction wheel 342 can be a ratchet, and the belt 330 is provided with equidistant holes that cooperate with the ratchet, and the teeth of the ratchet cooperate with the equidistant holes to achieve pulling the belt 330.

[0048] The traction wheel 342 may also be composed of two rollers. Since the two rollers clamp the web 330 and convey it, the web 330 can be conveyed.

[0049] Further, refer to Figure 4 and Figure 5 A track groove 221 is further provided in the heat sealing cavity 220 , and the free end of the roll tape 330 passes through the limiting gap and then extends into the track groove 221 .

[0050] Further, refer to Figure 2 The container 100 has a negative pressure device 110 installed in the receiving chamber 101. This device is used to create a negative pressure in the receiving chamber 101, thereby sucking the garbage bag downward and allowing it to adhere to the inner wall of the receiving chamber 101. Specifically, after the packed garbage bag is removed, the negative pressure device 110 can be used to suck the film of the garbage bag downward, causing the garbage bag to adhere to the inner wall of the receiving chamber 101, facilitating garbage collection.

[0051] Further, refer to Figure 2 The accommodating chamber 101 is also provided with an identification device 120. The garbage bag is provided with a label. The identification device 120 is used to identify the label and determine the height position of the garbage bag in the accommodating chamber. The identification device is connected to the controller of the garbage bin. Only after the identification device recognizes the label can the controller control the heat sealing device. This prevents the garbage bag from being heat-sealed when it is not in the heat-sealing position, thereby ensuring normal heat sealing.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
