[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1-2 and Figure 4 An embodiment of this utility model is provided: an easy-to-open compost cup lid, including a compost cup lid body 1, lifting blocks 2 are fixedly provided around the outer surface of the compost cup lid body 1, an exhaust port 3 is fixedly provided around the upper outer side of the compost cup lid body 1, a tear line 7 is fixedly provided on one side of the front end of the compost cup lid body 1, a fixing block 8 is fixedly provided at the lower end of one side of the front end of the compost cup lid body 1, and a sliding groove 6 is provided on the upper end of the multiple lifting blocks 2. The compost cup lid body 1 includes a base layer 101, an antibacterial layer 102 is fixedly provided on the inner surface of the base layer 101, and a waterproof layer 103 is fixedly provided on the outer surface of the base layer 101.
[0025] Specifically, the compost cup lid body 1 is a container lid for home composting, designed to promote the decomposition and composting process of organic waste while reducing odors and preventing pests from entering. The lifting block 2 facilitates the opening of the lid. This device has three ways to open the lid: the first is to directly lift the lid using the lifting block 2; the second is to slide the lifting belt mechanism 5 in the middle of the lifting block 2 and then lift the lid using the lifting belt mechanism 5; and the last is to tear a notch in the lid using the fixing block 8 and the tear line 7, thus opening it. Multiple opening methods allow users to choose flexibly. The vent 3 improves air permeability. The base layer 101 uses plant fiber pulp such as sugarcane bagasse and bamboo pulp as raw materials, which is environmentally friendly, compostable, and biodegradable. The antibacterial layer 102 uses a coating containing natural antibacterial components of tea tree oil, which helps inhibit the growth of microorganisms and maintain the hygiene of the composting environment. The waterproof layer 103 is made of plant wax material, which helps prevent moisture from penetrating into the inside of the lid and extends the service life of the lid.
[0026] Reference Figure 1-3Multiple exhaust ports 3 are internally fitted with filter box mechanisms 4. The multiple filter box mechanisms 4 include device boxes 401. Activated carbon particles 404 are movably arranged inside the multiple device boxes 401. Fixed covers 402 are fixedly installed at the upper end of the multiple filter box mechanisms 4 by bolts. A hydrophobic mesh 403 is fixedly installed at the lower end of both the multiple device boxes 401 and the multiple fixed covers 402. Multiple vent holes 405 are opened at the upper end of the multiple fixed covers 402. A pull rod 406 is fixedly installed at the middle position of the upper end of the multiple fixed covers 402. A lifting belt mechanism 5 is fitted at the upper end of multiple lifting blocks 2. The lifting belt mechanism 5 includes two fixed belts 501. Slider blocks 502 are fixedly installed on both sides of the lower end of the two fixed belts 501. A fixing groove 503 is opened in the middle of one of the two fixed belts 501.
[0027] Specifically, the device box 401 facilitates the storage of activated carbon granules 404, which in turn helps absorb odors from the exhaust gases. The fixed cover 402 helps prevent leakage of activated carbon granules 404. The hydrophobic mesh 403 prevents rainwater from entering the device box 401 and also limits the position of the activated carbon granules 404. The hydrophobic mesh 403 allows air to pass through but not water. The pull rod 406 facilitates opening the fixed cover 402. The fixing strap 501 works in conjunction with the slide 6 to facilitate lifting the cup lid directly. The slider 502 facilitates sliding installation in the slide 6. If the compost cup lid body 1 is damaged, the lifting strap mechanism 5 can be reused, saving resources. The fixing groove 503 facilitates the cross-fixation of the fixing strap 501.
[0028] Working principle: This device has three ways to open the cup lid. The first is to directly lift the cup lid by lifting block 2. The second is to slide the lifting belt mechanism 5 in the middle of lifting block 2 and then lift the cup lid by lifting belt mechanism 5. The last is to tear a notch in the cup lid by fixing block 8 and tearing line 7, so as to lift it. Multiple opening methods allow users to choose flexibly and make it easy to use. The exhaust port 3 is fixedly set at the upper outer perimeter of the compost cup lid body 1 to discharge the gas generated during the composting process.
[0029] Secondly, the filter box mechanism 4, which is snapped into the exhaust port 3, plays its role. The device box 401 of the filter box mechanism 4 contains activated carbon particles 404, which can absorb odors in the exhaust gas. The upper end of the device box 401 is fixed with a fixing cover 402 by bolts. Both the lower end of the fixing cover 402 and the device box 401 are fixed with a hydrophobic mesh 403, which can prevent rainwater from entering the device box 401 and limit the position of the activated carbon particles 404 while allowing air to pass through. The fixing cover 402 has multiple vent holes 405 to ensure gas circulation. If it is necessary to replace the activated carbon particles in the filter box mechanism 4, 404. The fixed cover 402 can be opened by the pull rod 406 fixedly installed at the middle of the upper end of the fixed cover 402. The antibacterial layer 102 fixedly installed on the inner surface of the base layer 101 of the compost cup cover body 1 is a coating containing natural antibacterial ingredients of tea tree oil, which inhibits the growth of microorganisms and keeps the composting environment hygienic. The waterproof layer 103 fixedly installed on the outer surface of the base layer 101 is made of plant wax material, which prevents water from penetrating into the cup cover and extends the service life of the cup cover. The base layer 101 uses plant fiber pulp such as sugarcane bagasse and bamboo pulp as raw materials, which has the characteristics of being environmentally friendly, compostable and biodegradable.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
