Description

Technical Field

[0001] This utility model relates to a smart trash can lid structure and belongs to the field of smart trash can technology. Background Technology

[0002] With increasing environmental awareness, smart trash cans have become widely used in many places. However, existing smart trash can lids have some problems during use, such as noise, impact, vibration, and poor sealing. These problems not only affect the user experience but may also impact the surrounding environment. For example, the lids generate significant noise when opening and closing, leading to a poor user experience and potentially causing noise pollution. Simultaneously, the impact and vibration issues with the lids may affect the structural stability of the trash can and even cause damage.

[0003] Furthermore, poor sealing performance can lead to odor emissions and liquid leakage, affecting the dryness and cleanliness of the trash can's interior. Moisture intrusion can cause the trash to become damp, further reducing the trash can's lifespan. Therefore, these problems with existing smart trash can lids urgently need to be addressed to meet users' needs for quiet, comfortable, hygienic, and environmentally friendly solutions.

[0012] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0013] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0015] See Figures 1 to 5This utility model introduces a trash can lid structure, including a lid body 1, a lid edge 2, and a cylindrical edge structure 3. The surface of the lid body 1 is provided with annular ribs 4 and radial ribs 5. The annular ribs 4 are formed with the geometric center of the lid body 1 as the center and the midpoint of the line segment from the center to the corner of the lid body as the radius, which can effectively disperse stress and enhance the structural strength of the lid body. The radial ribs 5 start from the corner or the midpoint of the edge of the lid body 1, extend radially and connect with the annular ribs 4, further improving the stability and deformation resistance of the lid body.

[0016] The edge of the cover 1 is connected to the cover edge 2. The cover edge 2 is provided with at least one circumferential protrusion 9 and multiple radial protrusions 12. In this embodiment, the number of radial protrusion structures 12 is 2 to 10. These protrusion structures are similar to the interlocking structure of a maze, which can not only effectively block odors and liquid leakage, but also significantly reduce the noise and impact force generated by the cover during opening and closing through its complex interlocking. Thus, after fitting with the cylinder edge structure 3, a sealed channel is formed. Example 2

[0017] See Figure 3 The cover 1 is generally rectangular in shape and made of carbon fiber. To enhance the rigidity of the cover 1, a reinforcing plate 7 runs across the entire surface of the front of the cover 1 and is secured by two fasteners 6. The shape features of the annular rib 4 and radial rib 5 on the back of the cover 1 are based on the matching of the first three modes of vibration. Compared with the traditional transverse or longitudinal rib layout, this can more efficiently disperse stress, improve the pressure-bearing capacity and deformation resistance of the cover, and reduce vibration noise.

[0018] The number of radial ribs 5 is 4-8, that is, they are evenly distributed with a step size of 45° or 90°. For example, if the included angle between the radial ribs 5 is 45°, then the endpoints of the radial ribs 5 extending outward are evenly distributed at the four corners and the middle edge of the cover body 1; if the included angle between the radial ribs 5 is 90°, then the endpoints of the radial ribs 5 extending outward are distributed at the four corners of the cover body 1.

[0019] In terms of the sealing structure, the cover edge 2 and the cylinder edge structure 3 form a maze-like interlocking structure through the circumferential protrusion 9 and the radial protrusion 12. The height of the circumferential protrusion 9 and the radial protrusion 12 are both 0.2mm~3mm, and the groove gap between the circumferential protrusion 9 and the radial protrusion 12 is 0.2~1mm to ensure the tight fit and sealing performance of the maze structure.

[0020] In another embodiment of this utility model, the material of the cylindrical rim structure 3 is soft rubber or silicone, with a thickness of 0.5mm to 1.5mm. This choice of material and thickness not only provides sufficient elasticity and wear resistance but also ensures a tight fit with the cap rim 2, thereby achieving a good sealing effect and effectively preventing odors and liquid leakage. Simultaneously, the softness of the rubber or silicone absorbs impact during the opening and closing of the cap, further reducing noise and vibration and improving the user experience.

[0021] See Figure 6 To improve the service life of the trash can, reduce noise pollution, enhance buffering performance, and prevent liquid spillage or odor leakage, a sealing buffer mechanism is installed at the end cap of the cover 1. This sealing buffer mechanism includes a sealing block 11 and a sealing ring 13. The sealing block 11 is made of rubber and has a 3-6mm diameter near-cubic structure. It is installed in a labyrinthine groove between the outermost and middle layers of the sealing ring 13. The sealing blocks 11 are evenly embedded in the labyrinthine groove at 30° intervals (with a 5° allowance), with 10-12 blocks embedded in each groove, and are distributed along the annular direction of the sealing ring 13.

[0022] Specifically, at the moment the lid closes, the evenly distributed sealing blocks 11 are simultaneously subjected to forces from multiple points, and cooperate with the elastic deformation of the sealing ring 13. This synergistic effect can effectively absorb and disperse the impact force generated when the lid closes, thereby making the sealing effect more secure and effectively preventing the emission of odors and the leakage of liquids.

[0023] See Figure 4 The sealing ring 13 has a groove depth of 5mm to 10mm and is installed above the sound insulation layer that fits against the body of the trash can. The sealing ring 13 includes a plastic gasket with a labyrinthine surface 8 of 1mm to 1.5mm thickness. The two are integrally formed to increase the contact area through the complex structure of the labyrinthine surface 8, thereby significantly improving the cushioning capacity and elasticity of the sealing ring, effectively absorbing the impact force when the lid is closed, and reducing vibration and noise. The labyrinthine surface 8 includes multiple buffer platforms 81, which have a structure that is high on both sides and low in the middle. The top of each buffer platform 81 is provided with a first arc 811 with a radius of 1mm to 1.5mm. The first arc 811 can disperse the impact force when the lid is closed, avoid local stress concentration, and thus extend the service life of the sealing ring. A second arc 812 with a radius of 1mm to 1.5mm is provided between two adjacent buffer platforms 81 to further enhance the cushioning effect, ensuring that the impact force when the lid is closed can be evenly distributed, reducing noise and vibration.

[0024] In addition, a third arc 813 with a size of 0.3mm-0.5mm is provided on both sides of the plastic gasket. The third arc 813 can not only further absorb the impact force of the edge, but also ensure the tight fit between the sealing ring 13 and the trash can body, effectively preventing liquid leakage and odor emission, and comprehensively improving the sealing performance and user experience.

[0025] In another embodiment of this utility model, the sealing buffer mechanism is further equipped with a damping buffer. The power of the damping buffer is 60W to 90W, and the reduction ratio is 5:1. One end of the damping buffer is fixed to the cover 1, and the other end is fixed to the trash can body. When the cover is opened and closed, the sealing buffer mechanism can play a buffering role, effectively avoiding the large impact force or noise generated by the rapid opening and closing of the cover. In particular, when the cover is about to close, the damping buffer starts to work, making the opening and closing action of the cover more gradual, further reducing impact and noise, and improving the user experience.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
