[0039] Garbage bag box A. Detailed Implementation
[0040] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0041] Before proceeding with the specific embodiments described below, it should be noted that the term "sealing" in this specification refers to maximizing the sealing performance of mechanical parts and components during installation, but does not imply absolute sealing. Furthermore, the special structural designs used to improve the sealing performance of connection structures, as specifically described in this specification, aim to achieve higher product sealing performance compared to conventional structural designs through unique structural design.
[0042] A garbage can bag-laying machine head includes a large cover assembly, a small cover assembly, and a bag-laying assembly.
[0043] Combination Figure 1 and Figure 2 As shown, the large cover assembly includes a housing 1. The housing 1 has a garbage bag mounting slot 2 for mounting a garbage bag container A, and a garbage storage inlet 3 for the garbage bag in the garbage bag container A to pass through. The garbage bag in the garbage bag container A passes through the garbage storage inlet 3 and enters the bottom of the bin. The housing 1 has an installation space 4 inside. The housing 1 has one or more air inlets 1-1. In this embodiment, after the bag-laying machine head is installed in the bin, the lower surface of the housing 1 is used to seal the internal space of the automated garbage bin, combined with... Figure 2As shown, in this embodiment, the air inlet 1-1 is located on the lower surface of the housing 1, facilitating air extraction from the interior of the trash can. For the user, there is no need for openings or holes on the exterior of the trash can, improving its overall appearance. The air inlet 1-1 not only maintains the trash can's appearance but also fulfills its function. Furthermore, its location on the lower surface of the housing 1 ensures protection, preventing moisture or water from entering the machine head in humid or wet environments, thus extending the trash can's lifespan. Of course, in other embodiments, the position of the air inlet 1-1 can be adjusted according to actual design requirements, such as placing it on the side of the housing 1.
[0044] The housing 1 is provided with a sealing structure mounting groove 1-2 at the position for mating with the small cover assembly. The mating position between the housing 1 and the small cover assembly refers to the position where the housing 1 and the small cover assembly can contact each other or not, but it needs to be a position that facilitates communication between the sealing structure mounting groove 1-2 on the housing 1 and the internal space of the small cover assembly. In this embodiment, the sealing structure mounting groove 1-2 is provided on the upper surface of the housing 1. Specifically, the sealing structure is provided between the housing 1 and the small cover assembly mainly to take into account that during the bag laying process, the fan will draw air from the bucket body (the location of the air inlet 1-1), and the bag laying action needs to consider the airtightness of the air outlet when laying the bag downwards. Therefore, in this embodiment, the bottom of the housing 1 is provided with an air inlet 1-1, the fan draws air from the bucket body with the garbage bag laid on it, and the air outlet is discharged downwards from the small cover (the air inlet channel is set on the small cover) to complete the bag laying. In this embodiment, the housing 1 includes a lower housing 1-3 and an upper housing 1-4. The air inlet 1-1 is opened in the lower housing 1-3, and the sealing structure mounting groove 1-2 is opened in the upper housing 1-4.
[0045] Meanwhile, the side of the housing 1 is provided with a rotating mounting opening 5, which provides mounting space for the rotating parts of the small cover assembly and the large cover assembly. The rotating parts of the small cover assembly and the large cover assembly can adopt any rotating mounting structure in the prior art, which will not be described in detail in this specification.
[0046] Combination Figure 1 , Figure 2 and Figure 4As shown, a small cover assembly is positioned above the large cover assembly, and the small cover assembly includes a cover plate 6. The cover plate 6 is used to cover the garbage bag box mounting slot 2 and the garbage storage inlet 3. To ensure efficient laying of garbage bags from the garbage bag box A installed in the garbage bag box mounting slot 2 to the garbage storage inlet 3, a sealing ring 7 for sealing the garbage storage inlet 3 is provided on the lower surface of the cover plate 6. The small cover assembly also includes an air inlet channel 8, one end of which is connected to the sealing structure mounting slot 1-2, and the other end of which is connected to the internal space of the sealing ring 7, ensuring the sealing of the entire air duct and thus ensuring the bag laying yield. In this embodiment, the air intake channel 8 is disposed on the lower surface of the cover plate 6. The air intake channel 8 includes an air intake pipe 8-1 and a connecting channel 8-2. The air intake pipe 8-1 is vertically disposed, with one end fixed to the lower surface of the cover plate 6 and the other end serving as a free end. When the cover plate 6 is closed, it makes a sealing contact with the sealing structure mounting groove 1-2. One end of the connecting channel 8-2 connects to the side of the air intake pipe 8-1, and the other end connects to the internal space of the sealing ring 7 from the side of the sealing ring 7.
[0047] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, to improve the success rate of bag laying, a sealing structure 9 is installed on the sealing structure mounting groove 1-2 to improve the sealing performance between the air intake channel 8 and the sealing structure mounting groove 1-2. In this embodiment, a sealing structure 9 is installed on the sealing structure mounting groove 1-2 to improve the sealing performance between the air intake pipe 8-1 and the sealing structure mounting groove 1-2. The sealing structure 9 includes a mounting part 9-1 and a sealing part 9-2. The mounting part 9-1 has an air passage for air circulation inside. The sealing part 9-2 is located at the top of the mounting part 9-1. The upper surface of the sealing part 9-2 has a protrusion 9-21 that conforms to the shape of the air intake pipe 8-1. The protrusion 9-21 has an opening 9-22 that communicates with the air passage for air circulation in the mounting part 9-1. When the small cover assembly is closed on the large cover assembly, the air intake pipe 8-1 is inserted and removed from the protrusion 9-21. Additionally, a sealing block 9-11 is provided at the bottom end of the mounting part 9-1. The sealing block 9-11 extends from the side of the mounting part 9-1 to form a sealing plane 9-12. When the mounting part 9-1 is installed in the sealing structure mounting groove 1-2, the sealing plane 9-12 fits against the lower surface of the sealing structure mounting groove 1-2, improving the sealing performance. Furthermore, to improve the sealing performance, the sealing structure 9 is made entirely of a soft material, resulting in better sealing when the air intake pipe 8-1 compresses the sealing part 9-2, and better sealing when the sealing plane 9-12 fits against the lower surface of the sealing structure mounting groove 1-2. For example, it is made of rubber material as used in the prior art.
[0048] At the same time, combined Figure 1 and Figure 7 As shown, the matching sealing ring 7 is equipped with a sealing ring 10, which is directly or indirectly fixed to the inner wall of the garbage bag box mounting groove 2. Alternatively, in other embodiments, the sealing ring 10 is directly installed on the sealing ring 7. In this embodiment, the sealing ring 10 is structured to include a sealing ring body 10-1 and a fixing ring 10-2. The fixing ring 10-2 is directly or indirectly fixed to the inner wall of the garbage bag box mounting groove 2, or the fixing ring 10-2 is directly installed on the sealing ring 7, while the sealing ring body 10-1 is sleeved on the outer periphery of the fixing ring 10-2. The garbage bag box mounting groove 2 has a mounting body 11 for installing garbage bag box A. Garbage bag box A is placed in the mounting body 11, and the sealing ring 10 is located at the top of the mounting body 11. When the small cover assembly closes the large cover assembly, the sealing ring 7 squeezes the sealing ring 10 to improve the sealing performance. That is, when the small cover assembly presses down on the large cover assembly to close the garbage storage inlet, the sealing ring 7 and the sealing ring body 10-1 are sealed and closed. To improve sealing performance, the sealing ring body 10-1 is made of a soft material, which results in better sealing performance when the sealing ring 7 compresses the sealing ring body 10-1.
[0049] It is important to note that the placement of the sealing ring 7 is designed to ensure the stable installation of the sealing ring 10. Furthermore, it addresses the height difference between the large and small cover assemblies—specifically, the height difference between the lower surface of the cover plate 6 and the upper surface of the housing 1. The sealing ring 7 effectively compensates for this height difference, ensuring a proper seal (guaranteeing an interference fit at the sealing structure 9) and providing more flexibility in choosing the sealing ring 10, eliminating the need to directly use it to compensate for the height difference between the large and small cover assemblies. The combination of sealing rings 7 and 10 further enhances the airtightness of the trash can, effectively reducing the possibility of odor leakage. In this embodiment, the sealing ring 7 is placed on the small cover assembly, which is also based on special considerations. First, it cleverly utilizes the weight of the small cover assembly itself to further ensure the interference fit at the sealing ring 10. Second, it takes into account that during daily use of the trash can, the small cover assembly mainly serves to open the lid, and the probability of contact with trash is lower compared to the large cover assembly. Placing the sealing ring 7 on the small cover assembly makes it less susceptible to contamination and damage, resulting in a longer service life. For users, the trash can presents a cleaner appearance when throwing away trash. Specifically, when throwing away trash, since the trash inlet is on the large cover assembly, users will pay more attention to the large cover assembly. If too many sealing components are designed on the large cover assembly, users will pay too much attention to other structures besides the trash inlet when throwing away trash. In this embodiment, users will only notice the sealing structure 9 on the large cover assembly, and the sealing structure 9 is small and will be overlooked by users during daily use.
[0050] Combination Figures 1-3 As shown, the bag-laying assembly is disposed inside the large cover assembly, i.e., configured in the installation space 4. The bag-laying assembly includes a mounting bracket 12 and a fan 13. The mounting bracket 12 is fixed inside the housing 1, and the fan 13 is arranged in the mounting bracket 12. The air inlet of the fan 13 is close to the air inlet 1-1, and the air outlet of the fan 13 is close to the sealing structure mounting groove 1-2. The fan 13 can be configured as an axial flow fan or a centrifugal fan in the prior art. In this embodiment, the fan 13 is configured as a centrifugal fan.
[0051] Based on the structure of the bag-laying head of the above-mentioned trash can, the bag-laying head is installed on the body of the automated trash can. In this embodiment, the lower housing 1-3 of the bag-laying head is sealed and installed on the body of the trash can. When the bag-laying head starts the bag-laying operation, the blower 13 is started. The blower 13 draws air from inside the trash can through the air inlet 1-1, then into the air intake channel 8 through the sealing structure mounting groove 1-2, then into the sealing ring 7, and finally blown into the trash bag released from the trash bag box through the trash storage inlet 3, laying the trash bag in the trash can body, completing the circulation of air from the trash can body back into the trash can body. Due to the setting of the air inlet 1-1, the sealing ring 10, and especially the sealing structure 9, the overall circuit sealing performance is better, and the bag-laying success rate is higher. The bag-laying success rate refers to the successful blowing of the trash bag from the trash bag box and its complete laying inside the trash can body. In the prior art, due to the large or small frictional resistance between the trash bag and the trash bag box, there is a possibility of failure in laying the trash bag. This patent improves the air circuit's sealing performance, ensuring the integrity of both positive and negative pressure processes, thereby increasing the success rate of bag laying.
[0052] It's clear that for automated trash cans, the bag-laying mechanism is a core functional component. In most existing automated trash cans, the bag-laying component is located at the bottom of the can, using negative pressure to achieve bag laying. However, this results in a scattered arrangement of components. For example, the bagging component is designed on the lid assembly, while the bag-laying component is on the can body. Since the can body also needs electronic components and circuits, the entire trash can, especially the can body, cannot be cleaned. This patent provides a feasible solution to move the bag-laying component from the can body (bottom) to the lid assembly. This allows all the electronic components and circuits of the automated trash can to be designed on the lid assembly (bag-laying head), eliminating the need for other electronic components and circuits on the can body. The lid assembly and the can body become relatively independent. This not only allows a single lid assembly to adapt to various can bodies (the lid assembly only needs to fit the opening of the can body), but also enables the can body to be disassembled and cleaned individually. For automated trash cans, the relative layout of various components and electronic devices is much more rational.
[0053] In addition, this specification also discloses a trash can that uses a bag-laying head with the aforementioned structure to improve the success rate of bag laying in automated trash cans.
[0054] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
