Description

Technical Field

[0001] This invention belongs to the field of trash can technology, and in particular relates to a self-sealing trash can. Background Technology

[0002] A trash can is a container for holding garbage or waste. To reduce the difficulty of cleaning, it is usually used in conjunction with a quick-change trash bag. A typical trash can mainly consists of a can body and a retractable lid. When in use, the retractable lid is opened and the trash bag is placed inside the can. After the garbage or waste is disposed of, the retractable lid is closed.

[0003] However, existing garbage bags typically have their openings folded outwards from the top of the bin. When the lid is closed, it only seals the opening of the bin, failing to effectively seal the bag opening. This makes it difficult to prevent odors from food waste or pet excrement, thus reducing air quality around the bin. Furthermore, the outward folding of the garbage bag reduces its effective storage space, lowering its actual usage rate. In addition, most garbage bin lids are manually operated, allowing users direct contact with garbage or waste, negatively impacting the user experience.

[0004] Therefore, there is an urgent need to develop a self-sealing trash can to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a self-sealing trash can that enhances the sealing effect of the trash bag opening, increases the actual utilization rate of the trash bag, improves the user experience, and enhances the air quality of the surrounding environment.

[0006] To achieve this objective, the present invention adopts the following technical solution: This invention proposes a self-sealing trash can, comprising: The trash can body includes a mounting frame and a can body. The mounting frame is connected to the top surface of the can body and has a vertically penetrating mounting chamber. The mounting chamber is connected to the can body. The trash bag is placed inside the can body with its opening facing upwards and at least partially extends into the mounting chamber. A sealing assembly is disposed in the installation chamber. The sealing assembly includes a first sealing auxiliary door, a second sealing auxiliary door, and a sealing drive unit. The first sealing auxiliary door and the second sealing auxiliary door are rotatably disposed on the opposite side of the wall of the installation frame along its own length direction, and are both drive-connected to the sealing drive unit. The sealing drive unit is configured to drive the first sealing auxiliary door and the second sealing auxiliary door to rotate relative to each other to clamp the bag opening of the garbage bag.

[0007] Optionally, the self-sealing trash can also include a transmission assembly, which includes a first transmission pulley, a second transmission pulley, a conveyor belt, a first slider, and a second slider. The first and second transmission pulleys are rotatably mounted on the mounting frame and spaced apart along the length of the mounting frame. The first transmission pulley is driven to the drive shaft of the sealing drive unit. The conveyor belt is wrapped around the outer periphery of the first and second transmission pulleys and meshes with them. The first slider is connected to the first sealing auxiliary door, and the second slider is connected to the second sealing auxiliary door. The first and second sliders are both mounted on the conveyor belt and are located on opposite sides of the conveyor belt in the vertical direction.

[0008] Optionally, conveyor belts are provided on both sides along the width direction of the mounting frame. The two conveyor belts are symmetrically arranged along the width direction of the mounting frame. Each conveyor belt has a first transmission pulley and a second transmission pulley meshed at both ends. The two first transmission pulleys are coaxially arranged and the two second transmission pulleys are coaxially arranged. The transmission assembly also includes a drive gear and a transmission gear. The drive gear is located on the drive shaft of the sealed drive unit. The transmission gear and one of the first transmission pulleys are coaxially arranged and meshed with the drive gear.

[0009] Optionally, the self-sealing trash can also include a position detection module, which includes a controller, magnetic sensors, and magnetic components. Multiple magnetic sensors are spaced apart along the length of the mounting frame. Both the first slider and the second slider are equipped with magnetic components. Each magnetic sensor is electrically connected to the controller and is used to detect the magnetic field strength of the magnetic components. The controller is used to acquire the detection data from multiple magnetic sensors to determine the position of the first slider and the second slider.

[0010] Optionally, both the first and second sliders are engaged with the conveyor belt.

[0011] Optionally, the self-sealing trash can also include a rotation auxiliary unit, which includes a first rotating arm and a second rotating arm. The first rotating arm is rotatably mounted on the wall of the mounting chamber, and one end of the second rotating arm is hinged to the first rotating arm, while the other end is connected to the first sealing auxiliary door.

[0012] Optionally, the first rotating arm includes a first rotating part and a second rotating part that are set at an angle and fixedly connected. The first rotating part is rotatably disposed on the cavity wall of the mounting chamber, and the second rotating part is hinged to the second rotating arm.

[0013] Optionally, a rotating groove is provided on the wall of the installation chamber, and the first rotating arm and the rotating groove are rotatably engaged.

[0014] Optionally, the sealing assembly also includes a seal sandwiched between the first and second auxiliary sealing doors and used to seal the upper opening of the mounting chamber.

[0015] Optionally, the trash can body also includes a top cover, which is hinged to the top surface of the mounting frame and is used to open and close the mounting chamber.

[0016] The beneficial effects of this invention are: This invention proposes a self-sealing trash can. A first and second sealing auxiliary door are rotatably mounted on opposite walls along the length of the mounting frame. A sealing drive unit drives the first and second sealing auxiliary doors to rotate relative to each other, clamping the opening of the trash bag. This achieves effective clamping of the trash bag opening compared to existing open trash cans or those only covered by a lid. The sealing component proposed in this invention enhances the sealing effect on the trash bag opening, significantly reducing odors emitted from the trash bag into the surrounding environment and improving air quality in the vicinity of the self-sealing trash can's usage environment. The rotation of the first and second sealing auxiliary doors is achieved by the sealing drive unit rather than manually, avoiding direct contact with the trash bag opening by the user, improving the user experience, and enhancing the convenience and efficiency of sealing the trash bag opening. The trash bag opening is placed upwards inside the can and at least partially extends into the mounting chamber, increasing the actual storage space for the trash bag compared to existing trash bags that fold outwards, thus improving the actual utilization rate of the trash bag.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-5As shown, this embodiment provides a self-sealing trash can, including a trash can body 1 and a sealing component 2. The trash can body 1 includes a mounting frame 11 and a can body 12. The mounting frame 11 is connected to the top surface of the can body 12 and has a vertically penetrating mounting chamber. The mounting chamber is connected to the can body 12. A trash bag is placed in the can body 12 with its opening facing upward and at least partially extends into the mounting chamber. The sealing component 2 is disposed in the mounting chamber and includes a first sealing auxiliary door 21, a second sealing auxiliary door 22, and a sealing drive unit 23. The first sealing auxiliary door 21 and the second sealing auxiliary door 22 are rotatably disposed on the opposite walls of the mounting frame 11 along their own length direction and are both driveably connected to the sealing drive unit 23. The sealing drive unit 23 is configured to drive the first sealing auxiliary door 21 and the second sealing auxiliary door 22 to rotate relative to each other to clamp the opening of the trash bag. It should be noted that in this embodiment, the relative rotation of the first sealing auxiliary door 21 and the second sealing auxiliary door 22 can clamp the opening of the garbage bag to prevent the garbage in the garbage bag from emitting odors, while the opposite rotation of the first sealing auxiliary door 21 and the second sealing auxiliary door 22 can provide an effective way to remove the garbage bag.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the first sealing auxiliary door 21 and the second sealing auxiliary door 22 are rotatably mounted on the opposite side of the wall along the length of the mounting frame 11. The sealing drive unit 23 can drive the first sealing auxiliary door 21 and the second sealing auxiliary door 22 to rotate relative to each other and clamp the opening of the garbage bag, thus achieving the clamping of the garbage bag opening. Compared with existing open garbage cans or garbage cans that are only covered by a lid, the sealing component 2 proposed in this embodiment enhances the sealing effect on the garbage bag opening, significantly reduces the odor emitted from the garbage bag into the surrounding environment, and improves the air quality around the self-sealing garbage can's usage environment. The rotation process of the first sealing auxiliary door 21 and the second sealing auxiliary door 22 is achieved by the sealing drive unit 23 rather than manually, avoiding the user from directly touching the opening of the garbage bag, improving the user experience, and also improving the convenience and efficiency of sealing the garbage bag opening of the self-sealing garbage can. The garbage bag opening is placed upwards inside the can body 12 and at least partially extends into the mounting chamber, which also increases the actual holding space of the garbage bag compared to existing garbage bags that are folded outwards, thus improving the actual utilization rate of the garbage bag.

[0025] Optionally, such as Figure 2As shown, the self-sealing trash can also includes a transmission assembly 3, which includes a first transmission pulley 31, a second transmission pulley 32, a conveyor belt 33, a first slider 34, and a second slider 35. The first transmission pulley 31 and the second transmission pulley 32 are rotatably mounted on the mounting frame 11 and spaced apart along the length of the mounting frame 11. The first transmission pulley 31 is driven to the drive shaft of the sealing drive unit 23. The conveyor belt 33 is wound around the outer periphery of the first transmission pulley 31 and the second transmission pulley 32 and meshes with them. The first slider 34 is connected to the first sealing auxiliary door 21, and the second slider 35 is connected to the second sealing auxiliary door 22. The first slider 34 and the second slider 35 are both mounted on the conveyor belt 33 and are located on opposite sides of the conveyor belt 33 in the vertical direction. The above configuration allows the first slider 34 and the second slider 35 to slide synchronously in opposite directions using only a single drive shaft of the sealing drive unit 23. This reduces the rotational drive cost of the first sealing auxiliary door 21 and the second sealing auxiliary door 22, ensures their synchronous rotation, and enhances the uniformity of their clamping on both sides of the garbage bag opening. The sliding of the first slider 34 and the second slider 35 is achieved through the transmission of the first transmission pulley 31, the second transmission pulley 32, and the conveyor belt 33, meeting the requirements of low-to-medium speed reciprocating drive operations and improving their sliding stability. In this embodiment, applying a vertical force to the first sealing auxiliary door 21 and the second sealing auxiliary door 22 cannot achieve movement of the first slider 34 and the second slider 35 along the length of the mounting frame 11. That is, after the first sealing auxiliary door 21 and the second sealing auxiliary door 22 close and clamp the garbage bag opening under the drive of the sealing drive unit 23, they have self-locking performance, improving the sealing reliability of the garbage bag opening. Compared to other transmission methods, the first transmission pulley 31, the second transmission pulley 32, and the conveyor belt 33 reduce the space occupied inside the installation chamber, improving the integration and space utilization of the components inside the installation chamber. It is important to note that the drive stroke of the sealing drive unit 23 ensures that the first slider 34 and the second slider 35 are always located on opposite sides of the vertical direction of the conveyor belt 33 during the opening and closing of the first sealing auxiliary door 21 and the second sealing auxiliary door 22. This prevents the first sealing auxiliary door 21 and the second sealing auxiliary door 22 from rotating in the same direction, which would prevent the bag opening from being effectively clamped.

[0026] Specifically, conveyor belts 33 are provided on both sides along the width direction of the mounting frame 11. The two conveyor belts 33 are symmetrically arranged along the width direction of the mounting frame 11. Each conveyor belt 33 has a first transmission pulley 31 and a second transmission pulley 32 meshing at both ends. The two first transmission pulleys 31 are coaxially arranged and the two second transmission pulleys 32 are coaxially arranged. The transmission assembly 3 also includes a drive gear 36 and a transmission gear 37. The drive gear 36 is located on the drive shaft of the sealed drive unit 23. The transmission gear 37 and one of the first transmission pulleys 31 are coaxially arranged and meshed with the drive gear 36. Compared to the direct drive shaft connection of the sealing drive unit 23 to the first transmission pulley 31 and the second transmission pulley 32, in this embodiment, the transmission effect of the first transmission pulley 31, the second transmission pulley 32, and the conveyor belt 33 on the first slider 34 and the second slider 35 is achieved by means of the drive gear 36 and the transmission gear 37. This reduces the instantaneous impact force of the sealing drive unit 23 on the first transmission pulley 31, enhances the sliding stability of the first slider 34 and the second slider 35, and thus improves the rotational safety and stability of the first sealing auxiliary door 21 and the second sealing auxiliary door 22. The mounting frame 11 is symmetrically provided with transmission components 3 on both sides along its width direction. Compared to a single-sided arrangement on the mounting frame 11, this improves the rotational reliability of the first sealing auxiliary door 21 and the second sealing auxiliary door 22 and reduces the risk of overload at the connection nodes. The two first transmission pulleys 31 and the two second transmission pulleys 32, located on both sides of the width of the mounting frame 11, are coaxially arranged. This enables the first sealing auxiliary door 21 and the second sealing auxiliary door 22 to rotate synchronously along both sides of the width of the mounting frame 11, reducing the risk of stress concentration at the connection points between the first sealing auxiliary door 21 and the first transmission pulleys 31, as well as at the connection points between the second sealing auxiliary door 22 and the second transmission pulleys 32. The transmission process of the transmission components 3 located on both sides of the mounting frame 11 is achieved by the same sealing drive unit 23, saving drive costs and improving the sealing economy of the self-sealing trash can.

[0027] More specifically, both the first slider 34 and the second slider 35 are engaged with the conveyor belt 33, enabling quick assembly and disassembly of the first slider 34 and the second slider 35. This reduces the difficulty of installation and the cost of disassembly, improving the ease of assembly and disassembly of the first slider 34 and the second slider 35. Compared to fixing them to the top or bottom surface of the conveyor belt, this also reduces the vertical space occupied by the mounting chamber, avoiding interference between the first slider 34 and the second slider 35 and the surrounding structures, and improving their sliding safety and reliability. In other embodiments, the first slider 34 and the second slider 35 can also be snapped or inserted into the conveyor belt 33, which is not specifically limited here.

[0028] Optionally, the self-sealing trash can also include a position detection module. The position detection module includes a controller, magnetic sensors 5, and magnetic components. Multiple magnetic sensors 5 are spaced apart along the length of the mounting frame 11. Both the first slider 34 and the second slider 35 are equipped with magnetic components. Each magnetic sensor 5 is electrically connected to the controller and is used to detect the magnetic field strength of the magnetic component. The controller acquires the detection data from the multiple magnetic sensors 5 to determine the position of the first slider 34 and the second slider 35. This configuration enables non-contact position sensing of the first slider 34 and the second slider 35, allowing real-time monitoring of their position and movement. This facilitates remote monitoring of the opening and closing status of the first sealing auxiliary door 21 and the second sealing auxiliary door 22, as well as whether they are rotating normally. It avoids misjudgments of the opening and closing status of the first sealing auxiliary door 21 and the second sealing auxiliary door 22, and their clamping status on the trash bag opening, ensuring the operational safety of the first sealing auxiliary door 21 and the second sealing auxiliary door 22, and the reliability of their clamping on the trash bag opening, thus ensuring a proper seal on the trash bag opening. It is understood that the magnetic sensor 5 in this embodiment can be a Hall sensor, and the magnetic component can be a permanent magnet. The specific structure of the magnetic sensor 5, the magnetic component and the controller, as well as the working principle of the controller coordinating with the magnetic sensor 5 and the magnetic component to perform position detection, are existing technologies and will not be described in detail here.

[0029] For example, the sealing drive unit 23 can be any type of rotary drive device such as an electric motor or a hydraulic motor. Its specific structure and working principle are all existing technologies and will not be described in detail here. In this embodiment, the sealing drive unit 23 can drive the ends of the first sealing auxiliary door 21 and the second sealing auxiliary door 22 that are far apart from each other to rotate upward to open the upper opening of the installation chamber, or drive the ends of the first sealing auxiliary door 21 and the second sealing auxiliary door 22 that are far apart from each other to rotate downward to close the upper opening of the installation chamber and clamp the bag mouth of the garbage bag. The downward rotation of the first sealing auxiliary door 21 and the second sealing auxiliary door 22 to clamp the bag mouth of the garbage bag reduces the risk of garbage overflow caused by accidentally clamping pet excrement or kitchen waste and other perishable garbage inside the garbage bag when the two rotate relative to each other.

[0030] In this embodiment, as Figure 3 and Figure 4As shown, the self-sealing trash can also includes a rotation auxiliary unit 4, which includes a first rotating arm 41 and a second rotating arm 42. The first rotating arm 41 is rotatably mounted on the wall of the mounting chamber, and one end of the second rotating arm 42 is hinged to the first rotating arm 41, while the other end is connected to the first sealing auxiliary door 21. The first sealing auxiliary door 21 is rotatably mounted on the wall of the mounting chamber by means of the hinged first rotating arm 41 and the second rotating arm 42. Compared to using a single rotating arm, this increases the rotation angle of the first sealing auxiliary door 21 within a limited space, reduces the space restriction required for rotation, facilitates assembly, reduces structural interference, and enhances the rotation versatility and flexibility of the first sealing auxiliary door 21.

[0031] Specifically, such as Figure 4 As shown, the first rotating arm 41 includes a first rotating part 411 and a second rotating part 412 that are angled together and fixedly connected. The first rotating part 411 is rotatably disposed on the cavity wall of the mounting chamber, and the second rotating part 412 is hinged to the second rotating arm 42. The first rotating arm 41, including the angled first rotating part 411 and the second rotating part 412, further reduces the space occupied inside the mounting chamber, enhances the rotational versatility and flexibility of the first rotating arm 41 in confined spaces, improves the bending and torsional resistance of the first rotating arm 41, extends the service life of the first rotating arm 41, and improves the structural durability of the first rotating arm 41.

[0032] More specifically, the angle between the first rotating part 411 and the second rotating part 412 is an obtuse angle, which increases the extension span of the first rotating part 411 and the second rotating part 412 along the length of the mounting frame 11 compared to an acute angle. This improves the load-bearing strength at the connection point and also allows the first rotating arm 41 to effectively avoid other components in the mounting chamber within the limited space, thus improving the rotation reliability and safety of the first rotating arm 41. It is understood that the rotation structure and principle of the second sealing auxiliary door 22 and the mounting chamber wall are similar to those of the first sealing auxiliary door 21 and the mounting chamber wall, and will not be elaborated further here. Through the above structural design, the first sealing auxiliary door 21 and the second sealing auxiliary door 22 can each achieve a maximum rotation of 75° during actual operation, effectively adapting to the sealing requirements of the sealing assembly 2 for the garbage bag opening in confined spaces.

[0033] For example, such as Figure 1 , Figure 3 and Figure 4As shown, a rotating groove 111 is provided on the wall of the installation chamber, and the first rotating arm 41 rotatably engages with the rotating groove 111. Compared to a rotating protrusion on the wall of the installation chamber that is rotatably connected to the first rotating arm 41, the rotating groove 111 reduces the space occupied inside the installation chamber, increases the actual space for the garbage bag to extend into the installation chamber, and further improves the actual utilization rate of the garbage bag. The groove wall of the rotating groove 111 near the first rotating arm 41 is arc-shaped, which not only ensures the rotational flexibility of the first rotating arm 41, but also reduces the size of the rotating groove 111, ensuring the structural strength of the installation frame 11 and the rotational reliability of the first rotating arm 41.

[0034] Furthermore, the sealing assembly 2 also includes a sealing element 24, which is sandwiched between the first sealing auxiliary door 21 and the second sealing auxiliary door 22, and is used to seal the upper opening of the installation chamber. The addition of the sealing element 24 enhances the sealing effect of the first sealing auxiliary door 21 and the second sealing auxiliary door 22 on the garbage bag opening, further reducing the emission of odors from perishable garbage inside the garbage bag and improving the air quality around the self-sealing garbage can's operating environment. The sealing gasket material can include silicone. Silicone has high flexibility and strong elastic deformation ability, which can adapt to the irregular deformation of the garbage bag opening, enhancing the clamping effect between the first sealing auxiliary door 21 and the second sealing auxiliary door 22 and the garbage bag opening, effectively preventing the diffusion of garbage odors inside the garbage can.

[0035] In this embodiment, as Figure 2 and Figure 5 As shown, the trash can body 1 also includes a top cover 13, which is hinged to the top surface of the mounting frame 11. The top cover 13 is used to open and close the mounting chamber. Based on the first sealing auxiliary door 21 and the second sealing auxiliary door 22 clamping the opening of the trash bag, the addition of the top cover 13 achieves a secondary seal between the trash bag and the external environment, preventing odors or moisture from leaking out of the trash bag, while also preventing the accumulation of insects or dust, further improving the overall airtight and odor-proof effect of the self-sealing trash can. The top cover 13 also provides protection for the various components of the transmission assembly 3 within the mounting chamber, improving the structural durability and operational stability of the transmission assembly 3, and extending its service life.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
