Description

Technical Field

[0001] This utility model belongs to the field of trash can technology, specifically relating to a trash can that forms a plastic seal around the opening. Background Technology

[0002] A diaper changing container is a hygienic container specifically designed for discarding and storing used baby diapers (especially disposable diapers). Its core function is to lock in odors through a sealed structure, thus maintaining fresh air in the home. However, existing diaper changing containers generally suffer from insufficient odor control: upon opening the lid, the airflow caused by the flipping action can easily cause odors to escape more quickly, affecting the user experience. With the continuous improvement of living standards, users have placed higher demands on the hygiene and ease of use of diaper changing containers.

[0003] To address the aforementioned issues, some improvements have been proposed in the prior art. For example, Chinese patent document CN 206984868U discloses an odor-proof partition device for garbage cans. This device includes a partition with a feeding inlet, and a door consisting of left and right covers at the feeding inlet. The two covers are hinged to the bottom of the partition and close the feeding inlet when they are coplanar. Simultaneously, a closing mechanism ensures the covers remain closed without external force. This structure can be installed between the lid and body of a covered garbage can to enhance odor prevention. While this device suppresses odor escape to some extent through its double-sealing structure, the internal left and right covers are directly exposed to the garbage disposal path, making them susceptible to contamination and increasing cleaning burden. Furthermore, while the normally closed design of the covers facilitates sealing, it hinders the garbage disposal process, requiring users to apply additional force to open the covers, resulting in poor operational convenience. Summary of the Invention

[0004] In response to the problems in related technologies, this utility model proposes a trash can with a plastic-shaped, partially sealed opening to solve the technical problems of easy contamination of the inner lid when preventing odors from escaping from existing trash cans, as well as the obstruction of trash disposal.

[0005] The technical solution of this utility model is implemented as follows: a trash can that forms a plastic seal for the opening includes a can body, the can body having a cavity for accommodating a trash bag; the upper end of the can body is provided with an inner opening communicating with the cavity; it also includes a hinged lid mechanism located on the outside of the trash bag, the hinged lid mechanism including an inner lid, and a drive module for driving the inner lid to open or close the inner opening.

[0006] The inner cover includes a first half cover and a second half cover that open and close relative to each other along a plane; the two half covers have a height difference at their opposing edges and are staggered when closed; or, the two half covers are flush with each other and abut against each other when closed; the garbage bag passes through the first half cover and the second half cover, and the opening of the garbage bag is fixed outside the inner opening.

[0007] When the first and second halves of the lid come close together, they apply pressure to the passing garbage bag, shaping it into a closed shape. When the two halves of the lid move away from each other, the opening of the garbage bag retains the shaped shape, forming a partial seal with the inside open.

[0008] This invention features a hinged lid mechanism that shapes and seals the garbage bag when the lid is closed, while maintaining a loose seal when the lid is opened. This not only effectively prevents odors from escaping when the lid is opened, but also automatically releases the loose seal when garbage is thrown, avoiding any obstruction to the throwing action. Furthermore, by placing the hinged lid mechanism on the outside of the garbage bag, the bag opening directly accommodates the thrown garbage, avoiding the problem of the traditional lid being exposed to the throwing path and becoming contaminated with dirt, thus significantly improving hygiene.

[0009] As a further improvement to the above solution, the upper end of the bin has an external opening connecting to the outside, and an external cover is provided at the external opening; an internal opening is provided below the external opening, forming a channel for garbage disposal between the internal and external openings; the hinged lid mechanism is located between the internal and external openings. By setting up a double sealing structure combining the external cover and the hinged lid mechanism, the overall odor prevention effect is significantly enhanced. The external cover effectively isolates the external environment, while the inner hinged lid mechanism forms a reliable internal odor barrier by shaping and partially sealing the garbage bag opening, reducing the risk of odor leakage upon opening the lid, while maintaining the smoothness of the disposal operation.

[0010] As a further improvement to the above solution, the garbage bag covers the opposing sides and adjacent surfaces of the first and second half-lids, completely isolating the inner lid from the inner cavity of the garbage bag. The hinged lid mechanism clamps the garbage bag from the outside to close it, ensuring that contaminants only contact the garbage bag and do not contaminate the inner lid during garbage disposal. By covering the opposing sides and adjacent surfaces of the inner lid with the garbage bag, a reliable physical barrier is established between the inner lid and contaminants, ensuring that contaminants only contact the garbage bag during garbage disposal and closure, fundamentally preventing contamination of the inner lid surface and significantly improving hygiene.

[0011] As a further improvement to the above solution, after the opening of the garbage bag is fixed, the garbage bag is in a relaxed state without being clamped by the two half-lids, allowing for some shaping allowance. By allowing the garbage bag to retain a moderate shaping allowance after fixing, it is ensured that the hinged lid mechanism can apply sufficient pressure to the opening of the bag when closing, so that it is reliably shaped into a closed form; at the same time, after the lid is opened, the opening of the bag can still maintain the shaped form, thereby achieving a stable partial seal.

[0012] As a further improvement to the above solution, when the two half-lids have a height difference between their opposing edges, both the first and second half-lids are horizontally positioned and parallel to each other. The height difference between them in the vertical direction is configured to allow them to intersect when closed. This spatial misalignment between the two half-lids guides the garbage bag to undergo multiple folds in three-dimensional space when closed. This spatial misalignment structure significantly increases the deformation of the bag opening, allowing it to maintain a more stable folded shape after the lid is opened, thereby greatly improving the reliability and durability of the partial seal and effectively suppressing odor escape. As a further improvement to the above solution, the edges of each half-lid are designed with a gradually decreasing thickness from the inside out. By setting the edges of each half-lid to have a gradually decreasing thickness from the inside out, the contact process with the garbage bag is optimized, allowing the half-lids to smoothly guide the bag opening material to fold when closed, greatly reducing shaping resistance; at the same time, it reduces interference with the already formed folds when opened, allowing the bag opening to maintain a more stable folded partial seal shape and improving the reliability of odor sealing.

[0013] As a further improvement to the above solution, an annular seat is provided above the hinged lid mechanism. The central opening of the annular seat is vertically continuous and communicates with the inner opening. An annular groove is provided around the circumference of the annular opening. After the garbage bag passes between the first half-lid and the second half-lid, its fixed end is accommodated in the annular groove. By setting the annular seat structure with an annular groove, a stable and concealed fixed accommodation space is provided for the garbage bag opening, so that all thrown garbage falls directly into the bag. This ensures that the hinged lid mechanism and the internal structure of the bin are completely isolated from the pollution path, fundamentally avoiding the problem of the inner lid easily getting contaminated with dirt in traditional designs.

[0014] As a further improvement to the above solution, an annular cap is also provided on the annular groove, and the annular cap has an outer opening in the middle; the annular groove includes an inner annular groove wall and an outer annular groove wall, and the annular cap presses against the upper edge of the outer annular groove wall, forming a gap between the annular cap and the upper edge of the inner annular groove wall for the garbage bag to pass through. Through the cooperation of the annular cap and the annular groove, the garbage bag is further secured, while the gap for the garbage bag to pass through allows the thrown garbage to be directly guided into the bag, ensuring hygiene during use.

[0015] As a further improvement to the above solution, the annular opening is connected to the upper edge of the inner annular groove wall in a curved transition along the circumference. By using a curved transition connection between the annular opening and the upper edge of the inner annular groove wall, a natural and smooth laying path is provided for the garbage bag body, reducing the frictional resistance of the garbage bag during installation and natural hanging, effectively avoiding scratches caused by sharp edges, and laying the foundation for subsequent reliable shaping and sealing.

[0016] As a further improvement to the above solution, the drive module includes a mounting base, and a drive rod and a threaded stud that are mutually driven and engaged on the mounting base.

[0017] The drive rod is connected to the outer cover in a transmission manner. The drive rod rises or falls vertically to drive the outer cover to flip open and close, while driving the screw thread to be axially fixed and rotate circumferentially.

[0018] The threaded studs are located on both sides of the drive rod and are respectively connected to the first half cover and the second half cover to drive the two half covers to open and close relative to each other along the plane.

[0019] Through the transmission connection between the drive rod and the screw groove, a single drive source can control the efficient linkage between the outer cover flipping and the opening and closing of the hinged cover mechanism, improving ease of use and ensuring the coordination of the inner and outer seals at the moment of opening the cover, thereby effectively suppressing the escape of odors.

[0020] As a further improvement to the above scheme, a connecting rod component is provided between each half-cap and the screw groove post;

[0021] The linkage component includes a first linkage and a second linkage; one end of the first linkage is fixedly connected to the threaded post, and the other end is hinged to the half-cover; one end of the second linkage is hinged to the mounting base, and the other end is hinged to the half-cover, forming a planar four-bar linkage structure; an elastic member is also connected between the two half-covers, which provides pre-tightening force for the closing of the inner cover. The planar four-bar linkage structure provides a precise and stable planar motion trajectory for the half-covers, reducing the risk of jamming during opening and closing, and ensuring that the half-covers can smoothly achieve staggered closing and opening. Combined with the pre-tightening force provided by the elastic member, the shaping and sealing actions of the garbage bag opening are stable and unified, effectively improving the reliability of the sealing effect.

[0022] Beneficial effects:

[0023] (1) By setting a hinged lid mechanism, the garbage bag itself is shaped and the bag opening is sealed when the lid is closed, and it remains loosely sealed when the lid is opened. The loosely sealed state of the garbage bag opening can not only effectively prevent odors from escaping at the moment the lid is opened, but also automatically releases the loosely sealed state when the garbage is thrown, avoiding obstruction to the throwing action. Users can throw garbage without touching the lid, which improves the convenience of use.

[0024] (2) The hinged lid mechanism is placed on the outside of the garbage bag, so that the opening of the garbage bag can directly hold the garbage thrown in, avoiding the problem of the traditional lid being exposed to the throwing path and getting contaminated, which significantly improves the sanitation.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] Example:

[0047] like Figures 1-6 As shown, this embodiment provides a trash can with a plastic-shaped, partially sealed opening, including a can body L2, which includes a can body L22 and a can head L21; the can body L22 has a can cavity L23 for accommodating a trash bag L3; the can head L21 is located on the upper part of the can body L22; the can head L21 has an outer opening K1 communicating with the outside; an outer cover G1 is provided at the outer opening K1; an inner opening K2 communicating with the can cavity L23 is provided below the outer opening K1; a channel T1 for trash disposal is formed between the inner opening K2 and the outer opening K1, and a hinged cover mechanism Q1 is located between the inner opening K2 and the outer opening K1.

[0048] It also includes a hinged lid mechanism Q1 located on the outside of the garbage bag L3. The hinged lid mechanism Q1 includes an inner lid G2 and a drive module Q2 that drives the inner lid G2 to open or close the inner opening K2. By setting up a double sealing structure combining the outer lid G1 and the hinged lid mechanism Q1, the overall odor prevention effect is significantly enhanced. The outer lid G1 effectively isolates the external environment, while the inner hinged lid mechanism Q1 forms a reliable internal odor barrier by shaping and partially sealing the opening of the garbage bag L3, reducing the risk of odor leakage when the lid is opened, while maintaining the smoothness of the disposal operation.

[0049] In this embodiment, the drive module Q2 includes a mounting base 1, and a drive rod 2 and a threaded stud 3 that are mutually driven and engaged on the mounting base 1. The drive rod 2 is driven and connected to the outer cover G1. The drive rod 2 rises or falls vertically to drive the outer cover G1 to flip open and close, while simultaneously driving the threaded stud 3 to be axially fixed and rotate circumferentially. The threaded stud 3 is located on both sides of the drive rod 2 and is driven and connected to the first half-cover G21 and the second half-cover G22 respectively to drive the two half-covers to open and close relative to each other along the plane. Specifically, the drive rod 2 is provided with at least one guide post 21; the columnar surface of the threaded stud 3 is provided with a constraint groove 31 that cooperates with the guide post 21. When the drive rod 2 drives the guide post 21 to rise or fall, the guide post 21 acts on the groove wall of the constraint groove 31, driving the threaded stud 3 to remain stationary or rotate around its axis.

[0050] Through the transmission connection between the drive rod 2 and the screw groove post 3, a single drive source can control the flipping of the outer cover G1 and the opening and closing of the hinged cover mechanism Q1, achieving efficient linkage, improving ease of use, and ensuring the synergy of inner and outer sealing at the moment of opening the cover, thereby effectively suppressing odor escape. Specifically, the drive rod 2 is provided with at least one guide post 21; the columnar surface of the screw groove post 3 is provided with a constraint groove 31 that cooperates with the guide post 21; when the drive rod 2 drives the guide post 21 to rise or fall, the guide post 21 acts on the groove wall of the constraint groove 31, driving the screw groove post 3 to remain stationary or rotate around its axis, thereby driving the inner cover G2 to open and close along the plane.

[0051] In this embodiment, a connecting rod component 5 is provided between each half-cover and the screw groove post 3; the connecting rod component 5 includes a first connecting rod 51 and a second connecting rod 52; one end of the first connecting rod 51 is fixedly connected to the screw groove post 3, and the other end is hinged to the half-cover; one end of the second connecting rod 52 is hinged to the mounting base 1, and the other end is hinged to the half-cover, forming a planar four-bar structure; an elastic component 4 is also connected between the two half-covers, and the elastic component 4 provides a pre-tightening force for the closing of the inner cover G2, and the elastic component 4 can be a tension spring. Through the planar four-bar structure, a precise and stable planar motion trajectory is provided for the half-covers, reducing the risk of jamming during the opening and closing process, and ensuring that the half-covers can smoothly achieve staggered closing and separation. Combined with the pre-tightening force provided by the elastic component 4, the shaping and loose sealing action of the garbage bag L3 opening is stable and unified, effectively improving the reliability of the sealing effect.

[0052] The inner cover G2 includes a first half-cover G21 and a second half-cover G22 that open and close relative to each other along the plane; the opposing edges G23 of the two half-covers have a height difference and are staggered when closed; or, the two half-covers are flush with each other and abut against each other when closed; the garbage bag L3 passes between the first half-cover G21 and the second half-cover G22, and the opening of the garbage bag L3 is fixed outside the inner opening K2; when the first half-cover G21 and the second half-cover G22 are relatively close, the two half-covers apply pressure to the passing garbage bag L3, shaping it into a closed bag opening shape; when the two half-covers are relatively separated, the opening of the garbage bag L3 retains the shaped shape, forming a partial seal on the inner opening K2.

[0053] In this embodiment, the garbage bag covers the opposing sides and adjacent surfaces of the first and second half-lids, completely isolating the inner lid from the inner cavity of the garbage bag. The hinged lid mechanism clamps the garbage bag from the outside to close it, ensuring that contaminants only contact the garbage bag and do not contaminate the inner lid during garbage disposal. By covering the opposing sides and adjacent surfaces of the inner lid with the garbage bag, a reliable physical barrier is established between the inner lid and contaminants, ensuring that contaminants only contact the garbage bag during garbage disposal and closure, fundamentally preventing contamination of the inner lid surface and significantly improving hygiene.

[0054] In this embodiment, after the opening of the garbage bag L3 is fixed, the garbage bag L3 is in a relaxed state without being clamped by the two half-lids, and has a shaping allowance. By allowing the garbage bag L3 to retain a moderate shaping allowance after fixing, it is ensured that the hinged lid mechanism Q1 can apply sufficient pressure to the opening of the bag when closing, so that it is reliably shaped into a closed form; at the same time, after the lid is opened, the opening of the bag can still maintain the shaped form, thereby achieving a stable partial seal.

[0055] In this embodiment, both the first and second half-lids are horizontally positioned and parallel to each other. The height difference between them in the vertical direction is configured to allow them to intersect when closed. This spatial misalignment between the two half-lids guides the garbage bag to undergo multiple folds in three-dimensional space when closed. This spatial misalignment structure significantly increases the deformation of the bag opening, enabling it to maintain a more stable folded shape after the lid is opened, thereby greatly improving the reliability and durability of the partial seal and effectively suppressing odor escape.

[0056] In this embodiment, the edges G23 of each half-cap are designed with a gradually decreasing thickness from the inside out. By setting the edges G23 of each half-cap to a structure with a gradually decreasing thickness from the inside out, the contact process with the garbage bag L3 is optimized, allowing the half-cap to smoothly guide the bag opening material to fold when closed, greatly reducing shaping resistance; at the same time, it reduces interference with the already formed folds when unpacking, allowing the bag opening to maintain a more stable folded and partially sealed shape, improving the reliability of odor sealing.

[0057] In this embodiment, an annular seat 6 is also provided above the hinged lid mechanism Q1. The annular opening in the middle of the annular seat 6 is vertically continuous and communicates with the inner opening K2. An annular groove 61 is provided around the annular opening. After the garbage bag L3 passes between the first half-lid G21 and the second half-lid G22, its fixed end is accommodated in the annular groove 61. By setting the annular seat 6 structure with the annular groove 61, a stable and concealed fixed accommodation space is provided for the opening of the garbage bag L3, so that all thrown garbage falls directly into the bag, ensuring that the hinged lid mechanism Q1 and the internal structure of the bin L2 are completely isolated from the pollution path, fundamentally avoiding the problem of the inner lid G2 being easily contaminated with dirt in traditional designs.

[0058] In this embodiment, a regular garbage bag can be used, with its opening folded over and fixed into the annular groove on the upper edge of the bin. A hook can be installed in the annular groove to hold the fixed end of the bag opening, allowing the middle of the bag to hang naturally through the middle of the inner lid, forming a cavity for holding garbage below the inner lid. Alternatively, a cylindrical garbage container specifically designed for automatic bagging bins can be used. This container has a structure that extends through both ends and is placed directly into the annular groove. In use, the lower end of the garbage bag is pulled out, tied, and passed between the two half-lids, forming a cavity for holding garbage below the inner lid. After the garbage bag is fixed in either case, it ensures that the garbage disposal path is completely isolated from the inner lid, meeting different usage needs.

[0059] In this embodiment, an annular cap 62 is also provided on the annular groove 61, and the annular cap 62 has the outer opening K1 in the middle. The annular groove 61 includes an inner annular groove wall 611 and an outer annular groove wall 612. The annular cap 62 presses against the upper edge of the outer annular groove wall 612, and a gap 63 is formed between it and the upper edge of the inner annular groove wall 611 for the garbage bag L3 to pass through. Through the cooperation between the annular cap 62 and the annular groove 61, the garbage bag L3 is further fixed, and the gap 63 for the garbage bag L3 to pass through is provided so that the thrown garbage is directly guided into the bag, ensuring hygiene. In this embodiment, the annular opening is circumferentially connected to the upper edge of the inner annular groove wall 611 with an arc-shaped surface 64. By using an arc-shaped surface 64 to transition between the ring opening and the upper edge of the inner ring groove wall 611, a natural and smooth laying path is provided for the garbage bag L3 body, reducing the frictional resistance of the garbage bag L3 during installation and natural descent, effectively avoiding scratches caused by sharp edges, and laying the foundation for subsequent reliable shaping and sealing.

[0060] In specific applications, the above-described solution of this utility model provides the following:

[0061] When a user throws away trash, the drive module Q2 causes the first half-cover G21 and the second half-cover G22 to retract relative to each other along the plane. The opening of the trash bag L3 remains in a partially sealed state, which not only effectively prevents odors from escaping when the cover is opened, but also automatically releases the partially sealed state when trash is thrown away, avoiding obstruction to the throwing action. At this time, the trash falls directly into the bag through the outer opening K1 and the inner opening K2. The opening of the trash bag L3 directly contains the thrown trash, avoiding the problem of the traditional cover being exposed to the throwing path and contaminated with dirt, significantly improving hygiene.

[0062] After the garbage bag is thrown, the drive module Q2 drives the two halves of the cover to close relative to each other along the plane. The staggered edges G23 with a height difference apply pressure to the passing garbage bag L3, shaping the bag opening into a closed shape again. Simultaneously, the outer cover G1 closes under the linkage, forming a double seal. This process can achieve sealing by utilizing the material characteristics of the traditional garbage bag L3 itself, which significantly suppresses the escape of odors and ensures the smoothness and hygiene of the throwing operation.

[0063] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
