Technical Field
[0001] This utility model relates to the technical field of lids, and in particular to a protective waste lid. Background Technology
[0002] In the treatment of various industrial, medical, and domestic wastes, waste containers are usually equipped with lids to prevent the spread of exhaust gases, leakage of odors, and splashing of waste. However, most existing waste lids have simple structures and only provide basic covering functions, failing to achieve good sealing and safety protection, especially in scenarios involving liquid or volatile wastes, where they still have many shortcomings.
[0003] First, traditional lids and waste bins often use simple interlocking or snap-fit connections, resulting in poor sealing and making them prone to fumes leakage, environmental pollution, and even discomfort or safety hazards for operators. Second, while some products are designed with openable lids to improve ease of use, they often lack a cushioning structure during opening, making them susceptible to impact damage or pinching injuries from the lid falling. Furthermore, the amount of waste inside the bin cannot be observed when the lid is closed, requiring users to frequently open it for inspection, which is cumbersome and poses a risk of secondary contamination.
[0004] In view of this, the inventor has designed a protective waste cover, which leads to this invention. Utility Model Content

[0007] In a further embodiment, the buffer mechanism includes a spring disposed between the protective cover and the cover.
[0008] In a further embodiment, the spring is a compression spring and is located in the inner cavity structure on both sides of the hinge.
[0009] In a further embodiment: the observation window is made of transparent polycarbonate and is sealed to the window portion of the protective cover with adhesive strips.
[0010] In a further embodiment: the vent valve includes a one-way valve mounted on a protective cover and a removable filter element, the filter element being used to filter harmful gases in the exhaust gas.
[0011] In a further embodiment, the filter element comprises at least one of activated carbon material, a nonwoven fabric layer, or a PTFE membrane layer.
[0012] In a further embodiment, the outer edge of the cover is provided with multiple snap-fit structures, which are interlocked with the limiting groove of the waste bin through elastic claws.
[0013] In a further embodiment, the sealing ring is a soft silicone ring, and it is embedded and fixed to the inner side of the bottom edge of the cover.
[0014] In a further embodiment, the opening end of the protective cover is provided with a limiting protrusion, which cooperates with a corresponding limiting groove on the cover to limit the maximum opening angle of the protective cover.

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0021] like Figure 1 As shown, this utility model provides a protective waste cover, mainly including a cover body 1, a protective cover 2, a sealing ring 11, a snap-fit structure 3, a buffer mechanism 4, a vent valve 5, and an observation window 6. The components are compactly structured and functionally coordinated, together forming a protective waste sealing device with good sealing performance, high safety, and ease of use.
[0022] like Figure 1 and Figure 2 As shown, the cover 1 is an approximately circular shell structure, with a sealing ring 11 at its bottom for engaging with the opening of the waste bin. The sealing ring 11 is preferably a soft silicone ring, which enhances the sealing performance between the cover 1 and the waste bin, and is fixed in a groove at the bottom edge of the cover 1 via an embedded structure, thus preventing it from falling off during opening or movement.
[0023] The protective cover 2 is connected to the upper surface of the cover 1 via a hinge structure, and one end of it can be flipped open or closed relative to the cover 1. To prevent structural damage caused by excessive opening angle of the protective cover 2, a limiting protrusion is preferably provided at the opening end of the protective cover 2, which works in conjunction with the corresponding limiting groove on the cover 1 to limit its maximum opening angle. The protective cover 2 mainly serves to isolate, protect, and prevent splashing, thereby improving safety during operation.
[0024] like Figure 3 and Figure 4 As shown, to further enhance safety, a buffer mechanism 4 is provided between the protective cover 2 and the cover 1. This buffer mechanism 4 can be a spring assembly, especially a compression spring, and is located in the inner cavity structure on both sides of the hinge. It provides effective buffering during the closing of the protective cover 2 to prevent risks such as impact and pinching caused by excessive falling speed.
[0025] The outer side of the cover 1 is equipped with multiple snap-fit structures 3, which engage with the limiting grooves on the waste bin via elastic claws to achieve quick installation and removal, facilitating maintenance and replacement, while ensuring a firm and reliable connection. The snap-fit structures 3 can be symmetrically distributed to improve the overall sealing performance and stress balance.
[0026] like Figure 4 As shown, to regulate the internal air pressure and control exhaust gas emissions, a vent valve 5 is provided on the cover 1 or protective cover 2. The vent valve 5 is preferably located at the top of the protective cover 2, and includes a one-way valve 51 structure and a removable filter element 52, which can filter harmful components in the exhaust gas while ensuring internal pressure balance. The filter element 52 can be made of materials such as activated carbon, non-woven fabric, or PTFE membrane to meet different gas filtration requirements.
[0027] A transparent observation window 6 is also provided on the protective cover 2 for real-time monitoring of the storage status of waste in the bin. The observation window 6 is preferably made of transparent polycarbonate material, which has good impact resistance and light transmission, and is fixedly installed at the opening of the protective cover 2 by a chemically resistant sealing strip 61 to ensure safe use under different working conditions.
[0028] like Figure 3 As shown, in addition, to further improve the stability of the cover 1 and the protective cover 2 after they are closed, a magnetic attraction component 7 is also provided between the two in this embodiment. When the protective cover 2 is closed, the magnetic attraction structure automatically attracts the cover, effectively preventing vibration and loosening, and improving the overall airtightness.
[0029] In summary, this protective waste cover overcomes the technical problems of poor sealing, inconvenient observation, impact during opening, and gas leakage in the prior art through the reasonable arrangement and functional coordination of the above-mentioned components. It is suitable for safe sealing and management of waste containers in medical, laboratory, and industrial settings.
