Description

Technical Field

[0001] This invention relates to the field of trash can technology, and in particular to a semi-automatic sealing and packaging trash can and its usage method. Background Technology

[0002] With the increasing number of pet owners, the collection and disposal of pet feces has become a pressing hygiene problem in home life. When using ordinary trash cans, pet feces are directly put into the trash bag. After the trash bag is full, the user needs to manually lift the bag opening, close it, tie a knot to seal it, and then take it out to throw away. This manual sealing method is not only cumbersome, time-consuming, and laborious, but the bag opening is also prone to not sealing tightly, causing odors to continue to spread and pollute the indoor environment.

[0003] To address the aforementioned issues, existing technology CN109969643A proposes a garbage bin with a garbage bag sealing function. This bin uses an internal movable partition to separate the cavities and a baling mechanism to seal the garbage bags, thus partially replacing manual sealing. However, this solution still has the following shortcomings in practical applications: Firstly, the movable partition only opens after a certain amount of feces has accumulated, allowing the garbage to fall into the bottom collection cavity, resulting in delayed separation between the disposal area and the collection area. Secondly, during daily use, the disposal area is directly connected to the outside, leading to continuous leakage of fecal odor.

[0004] Therefore, there is an urgent need to provide a semi-automatic sealing and packaging trash can that can isolate odors and is easy to operate, in order to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a semi-automatic sealing and packaging trash can and its usage method, which can not only isolate odors but also be easy to operate.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows: A semi-automatic sealing and packaging trash can, characterized in that it comprises: The main components include a bucket body, a middle frame, and a top cover that are rotatably connected from bottom to top. The top of the middle frame is recessed with a box for storing unbroken garbage bags. The garbage bags extend from the box body and enter the bucket body downwards. A sealing mechanism, installed in the middle frame, includes a drive assembly and two sealing doors. The drive assembly can drive the two sealing doors to rotate to close or open the channel of the middle frame, and the garbage bag passes through the two sealing doors. A sealing mechanism, installed at the bottom of the middle frame and capable of being inserted into the bin, is used to seal and melt the garbage bag; The monitoring component includes a first Hall effect switch, a second Hall effect switch, and a third Hall effect switch, all of which are communicatively connected to the drive component. The first Hall effect switch is located at the bottom of the top cover, the second Hall effect switch is located at the middle frame, and the third Hall effect switch is located at the top of the barrel. When the first Hall effect switch detects that the top cover is closed, the drive component drives the two sealing doors to open. After the second Hall effect switch detects that the doors are fully opened, the drive component drives the two sealing doors to close. After the second Hall effect switch detects that the doors are fully closed, the drive component stops. When the third Hall effect switch detects that the middle frame is open, the drive component drives the two sealing doors to open to a preset gap. When the third Hall effect switch detects that the middle frame is closed, the drive component drives the two sealing doors to close.

[0007] Furthermore, the semi-automatic sealing and packaging trash can also includes a button, which is installed on the outer surface of the middle frame and is communicatively connected to the drive component. When the button is triggered, the drive component can drive the two sealing doors to open or close, and the monitoring signal of the second switch Hall is shielded until the first switch Hall detects that the top cover is closed and then recovers.

[0008] Furthermore, the top surface of the barrel is provided with a snap-fit ​​component, which includes an insert plate and a protrusion, with the protrusion located on the side of the insert plate; correspondingly, the bottom of the intermediate frame is provided with a slot, and the outer wall of the intermediate frame is provided with a snap hole communicating with the slot, the insert plate is inserted into the slot, and the protrusion is snapped into the snap hole.

[0009] Furthermore, an annular groove is formed on the top surface of the intermediate frame, and two first sliding holes and two clearance holes are formed on both sides of the annular groove along the first direction. The first sliding holes extend along the second direction, which is perpendicular to the second direction. The sealing mechanism further includes: A ring frame is installed in the annular groove. The ring frame has two second sliding holes extending along the second direction on both sides along the first direction. The second sliding holes are connected to the first sliding holes on the corresponding sides. Four movable rods are provided, and each of the sealing doors is rotatably connected to the movable rods on opposite sides along the first direction. The four movable rods are respectively inserted through the four first sliding holes and the four second sliding holes and are rotatably connected to the drive assembly. Four connecting rods are provided, and each of the sealing doors is rotatably connected to both ends along the first direction. The connecting rods pass through the clearance holes and are rotatably connected to the annular frame. The drive assembly is mounted on the annular frame and located in the annular groove. It can simultaneously drive the moving rods on both sides to move towards or away from each other along the second direction, so that the two sealing doors rotate towards or away from each other, thereby closing or opening the passage.

[0010] Furthermore, the driving component includes: A driving component is mounted on the annular frame and housed within one end of the annular groove along the second direction; The drive wheel is connected to the output end of the drive component; The driven wheel meshes with the driving wheel; A transmission rod is fixedly inserted through the driven wheel and extends along a first direction, with both ends rotatably connected to the intermediate frame; Four transmission wheels, two of which are fixedly sleeved on both ends of the transmission rod along the first direction, and the other two transmission wheels are rotatably installed in the groove at the other end of the annular groove along the second direction; Two transmission belts are correspondingly wound around the two sets of transmission wheels at both ends of the transmission rod along the first direction; Four movable blocks are fixedly sleeved on the upper and lower belt bodies of each transmission belt, and four movable rods are rotatably inserted through the four movable blocks.

[0011] Furthermore, the sealing mechanism includes a housing, a wrench, a cam, a first slider, a first elastic element, a silicone head, and a heating assembly. The housing is mounted on the bottom surface of the intermediate frame, and the top of the housing is recessed inward to form a limiting groove. The housing has an accommodating cavity inside, which is divided into a first cavity and a second cavity from the position of the limiting groove. The first cavity and the second cavity each have an opening communicating with the limiting groove on their opposite sides. The wrench is rotatably mounted on the housing. The cam is fixedly connected to the rotating shaft of the wrench and located in the first cavity. The first slider is slidably mounted in the first cavity. The first elastic element is located in the first cavity and connected to the first slider and the housing. The silicone head is connected to the first slider. The heating assembly is mounted in the second cavity and partially protrudes from the corresponding opening. When the wrench drives the cam to rotate, the cam pushes the first slider to slide towards the limiting groove and drives the silicone head through the corresponding opening into the limiting groove, where it clamps the garbage bag relative to the heating assembly, thus sealing and melting the bag.

[0012] Furthermore, the sealing mechanism also includes a micro switch, which is disposed on the inner wall of the first cavity. A pressing part is protruding from the side of the first slider. When the first slider moves to the pressing part and presses the micro switch, the heating component starts heating.

[0013] Furthermore, the sealing mechanism also includes a second elastic element and a second slider. The first slider has a receiving groove on the side facing the opening. The second slider is slidably inserted into the receiving groove. The second elastic element is connected to the bottom of the receiving groove and the second slider. The silicone head is connected to the end of the second slider away from the second elastic element.

[0014] Furthermore, the bottom surface of the barrel is provided with multiple support feet spaced apart in a circumferential direction.

[0015] The method of using the semi-automatic sealing and packing trash can, as described above, includes: When you need to dispose of garbage, open the top cover to dispose of the garbage, then close the top cover and wait for the preset time. When you need to pack your trash, open the middle frame, manually operate the sealing mechanism to seal and melt the trash bag, then take out the sealed trash bag and throw it away. Next, manually pull the new trash bag down into the bottom of the bin, and finally close the middle frame.

[0016] The beneficial effects of this invention are: The semi-automatic sealing and packaging trash can proposed in this invention includes a bin body, a middle frame, and a top cover that are rotatably connected from bottom to top. The middle frame contains a box for storing unbroken trash bags. Two sealing doors driven by a drive component are installed in the middle frame, and the trash bags are placed between the two sealing doors. A manual sealing mechanism is provided on the top of the bin body. Three Hall effect switches connected to the drive component are also provided to monitor the status of the top cover, the middle frame, and the sealing doors, respectively, so as to realize the linkage control of automatic delayed opening and closing of the sealing doors after the top cover is closed, opening of the sealing doors to a preset gap after the middle frame is opened, and automatic closing of the sealing doors after the middle frame is closed.

[0017] During the waste disposal process, after the user opens the top cover to dispose of pet waste and closes it, a first Hall effect sensor located at the bottom of the top cover detects the closed signal and immediately triggers the drive assembly to open the two sealing doors. Once the second Hall effect sensor detects that the sealing doors are fully open, the drive assembly then closes the two sealing doors, stopping once they are fully closed. This automatic opening-then-closing action ensures that the pet waste falls to the bottom of the bin by gravity the instant the sealing doors open, while the sealing doors quickly re-clamp the garbage bag, isolating the odor inside the bin from the outside. Users do not need to perform any additional operations to complete the automatic sealing after disposal, avoiding the problem of continuous odor leakage after disposal, as with traditional garbage bins.

[0018] During the garbage storage process, the two sealed doors remain closed, clamping and sealing the garbage bags to prevent odors inside the bin from escaping upwards through the channel in the middle frame.

[0019] When the garbage bag needs to be replaced, the user opens the middle frame. The third Hall effect sensor in the middle frame detects the opening signal and triggers the drive assembly to open the two sealing doors to the preset gap. The user then manually operates the sealing mechanism to seal and sew the garbage bag between the two sealing doors. The sealed garbage bag remains at the bottom of the bin and can be removed and disposed of. After sealing, the user manually pulls the new garbage bag down from the top, allowing it to pass through the two sealing doors to the bottom of the bin. Then, the user closes the middle frame. Upon detecting the closing signal, the third Hall effect sensor triggers the drive assembly to completely close the two sealing doors.

[0020] Therefore, this invention achieves odor isolation throughout the entire process from dispensing and storage to packaging. Users only need to manually operate the packaging seal and pull out a new bag; all other sealing actions are automatically completed by the monitoring and drive components, ensuring both sealing effectiveness and improved ease of use.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 11 As shown, this invention provides a semi-automatic sealing and packaging trash can, including a main component 1, a sealing mechanism 2, a sealing mechanism 3, and a monitoring component. The main component 1 includes a bin body 11, a middle frame 12, and a top cover 13, which are rotatably connected from bottom to top. The top of the middle frame 12 has a recessed box 14 for storing unbroken trash bags. The trash bag extends out of the box 14 and enters the bin body 11 downwards. The sealing mechanism 2 is installed on the middle frame 12 and includes a drive component 21 and two sealing doors 22. The drive component 21 can drive the two sealing doors 22 to rotate to close or open the channel of the middle frame 12, and the trash bag passes between the two sealing doors 22. The sealing mechanism 3 is installed at the bottom of the middle frame 12 and can be inserted into the bin body 11 for sealing and sealing the trash bag. The monitoring component includes components connected to the drive component 21. The drive assembly 21 is communicatively connected to a first Hall effect switch 41, a second Hall effect switch 42, and a third Hall effect switch 43. The first Hall effect switch 41 is located at the bottom of the top cover 13, the second Hall effect switch 42 is located at the middle frame 12, and the third Hall effect switch 43 is located at the top of the barrel body 11. When the first Hall effect switch 41 detects that the top cover 13 is closed, the drive assembly 21 drives the two sealing doors 22 to open. When the second Hall effect switch 42 detects that the two sealing doors 22 are fully open, the drive assembly 21 drives the two sealing doors 22 to close. When the second Hall effect switch 42 detects that the two sealing doors 22 are fully closed, the drive assembly 21 stops. When the third Hall effect switch 43 detects that the middle frame 12 is open, the drive assembly 21 drives the two sealing doors 22 to open to a preset gap, and vice versa.

[0029] like Figures 2 to 4As shown, during the garbage disposal process, after the user opens the top cover 13 to dispose of pet feces and closes it, the first switch Hall 41 located at the bottom of the top cover 13 detects the closed signal and immediately triggers the drive component 21 to open the two sealing doors 22. After the second switch Hall 42 detects that the sealing doors are fully open, the drive component 21 then drives the two sealing doors 22 to close, stopping once they are fully closed. This automatic opening and closing action ensures that the pet feces fall to the bottom of the bin 11 by gravity the instant the sealing doors 22 open, while the sealing doors 22 quickly re-clamp the garbage bag, isolating the odor inside the bin from the outside. The user can complete the automatic sealing after disposal without any additional operation, avoiding the problem of continuous odor leakage after disposal in traditional garbage bins.

[0030] During the garbage storage process, the two sealed doors 22 are always closed, clamping and sealing the garbage bag, preventing odors inside the bin 11 from escaping upwards through the channel of the middle frame 12.

[0031] like Figure 5 As shown, when the garbage bag needs to be replaced, the user opens the middle frame 12. The third switch Hall 43 located in the middle frame 12 detects the opening signal of the middle frame 12, and the drive component 21 drives the two sealing doors 22 to open to the preset gap. The user then manually operates the sealing mechanism 3 to seal and melt the garbage bag between the two sealing doors 22. The sealed garbage bag remains at the bottom of the bin 11, which the user can remove and discard. After sealing, the user manually pulls the new garbage bag down from the top, allowing it to pass through the two sealing doors 22 into the bottom of the bin 11, and then closes the middle frame 12. After the third switch Hall 43 detects the closing signal, the drive component 21 drives the two sealing doors 22 to close completely.

[0032] Therefore, this invention achieves odor isolation throughout the entire process from dispensing and storage to packaging. Users only need to manually operate the packaging seal and pull out a new bag; all other sealing actions are automatically completed by the monitoring component and drive component 21, ensuring both sealing effectiveness and improved ease of use.

[0033] It should be noted that the trigger signal processing of the first switch Hall 41, the second switch Hall 42 and the third switch Hall 43 and the linkage algorithm with the drive component 21 are conventional technical means in this field, and will not be described in detail here.

[0034] In this embodiment, the garbage bin 11 has a capacity of 8L, and the garbage bag storage box 14 has a capacity of 2L.

[0035] Specifically, such as Figures 6 to 8As shown, the top surface of the middle frame 12 has an annular groove. Two first sliding holes and two clearance holes are formed on both sides of the annular groove along the first direction. The first sliding holes extend along the second direction, which is perpendicular to the second direction. The sealing mechanism 2 also includes an annular frame 23, four moving rods 24, and four connecting rods 25. The annular frame 23 is installed in the annular groove. Two second sliding holes extending along the second direction are formed on both sides of the annular frame 23 along the first direction, and the second sliding holes communicate with the corresponding first sliding holes on the corresponding sides. Each sealing door 22 has two... Each side of the sealing door 22 is rotatably connected to a movable rod 24, and the four movable rods 24 are respectively inserted through four first sliding holes and four second sliding holes and rotatably connected to the drive assembly 21; each sealing door 22 is rotatably connected to two ends along the first direction by a connecting rod 25, which is inserted through an avoidance hole and rotatably connected to the annular frame 23; the drive assembly 21 is mounted on the annular frame 23 and located in the annular groove, and can simultaneously drive the movable rods 24 on both sides to move towards or away from each other along the second direction, so that the two sealing doors 22 rotate towards or away from each other, thereby closing or opening the passage. See also Figure 6 and Figure 7 The X direction is the first direction, and the Y direction is the second direction. The drive assembly 21, moving rod 24, and connecting rod 25 are integrated into a single module via the annular frame 23. During assembly, the annular frame 23 is simply placed into the annular groove for installation, eliminating the need for individual part alignment and simplifying the assembly process. The drive assembly 21 simultaneously drives the moving rods 24 on both sides to move towards or away from each other. Under the constraint and guidance of the connecting rod 25, the two sealing doors 22 can rotate synchronously and smoothly, thereby accurately closing or opening the channel and ensuring the synchronicity and reliability of the sealing action.

[0036] More specifically, the drive assembly 21 includes a drive member 211, a drive wheel 212, a driven wheel 213, a transmission rod 214, four transmission wheels 215, two transmission belts 216, and four moving blocks 217. The drive member 211 is mounted on the annular frame 23 and accommodated in one end of the annular groove along the second direction. The drive wheel 212 is connected to the output end of the drive member. The driven wheel 213 meshes with the drive wheel. The transmission rod 214 is fixedly threaded through the driven wheel 213 and extends along the first direction, with both ends rotatably connected to the intermediate frame 12. Two transmission wheels 215 are fixedly sleeved on both ends of the transmission rod 214 along the first direction, and the other two transmission wheels 215 are rotatably mounted in the other end of the annular groove along the second direction. The two transmission belts 216 are correspondingly wound around the two sets of transmission wheels 215 at both ends of the transmission rod 214 along the first direction. Each transmission belt 216 has a moving block 217 fixedly sleeved on its upper and lower belt bodies, and the four moving rods 24 are correspondingly rotatably threaded through the four moving blocks 217. The drive unit 211 transmits power to the moving block 217 through the linkage of the drive wheel 212, driven wheel 213, transmission rod 214, transmission wheel 215 and transmission belt 216, which drives the moving rod 24 to move; the two transmission belts 216 operate synchronously, ensuring the consistency of the actions of the two sealing doors 22; at the same time, all components are integrated into the annular frame 23 and annular groove, which has a compact structure and high space utilization.

[0037] In this embodiment, the driving component 211 is a motor.

[0038] More specifically, the transmission wheel 215 is a gear, and the transmission belt 216 is a toothed belt that meshes with the transmission wheel 215. This meshing method can prevent slippage during transmission, ensure precise synchronization of the opening and closing actions of the two sealing doors 22, and improve the reliability and stability of the transmission.

[0039] Specifically, such as Figures 9 to 11As shown, the sealing mechanism 3 includes a housing 31, a wrench 32, a cam 33, a first slider 34, a first elastic element 35, a silicone head 36, and a heating assembly 37. The housing 31 is mounted on the bottom surface of the intermediate frame 12. The top of the housing 31 is recessed inward to form a limiting groove. The housing 31 has an internal cavity, which is divided into a first cavity and a second cavity from the position of the limiting groove. The first cavity and the second cavity each have an opening on their opposite sides that connects to the limiting groove. The wrench 32 is rotatably mounted on the housing 31, and the cam 33 is fixedly connected to the rotating shaft of the wrench 32. Located within the first cavity, the first slider 34 is slidably installed within the first cavity. A first elastic element 35 is located within the first cavity and connected to the first slider 34 and the outer shell 31. A silicone head 36 is connected to the first slider 34. A heating component 37 is installed within the second cavity and partially protrudes from the corresponding opening. When the wrench 32 drives the cam 33 to rotate, the cam 33 pushes the first slider 34 towards the limiting groove, causing the silicone head 36 to pass through the corresponding opening and enter the limiting groove, clamping the garbage bag against the heating component 37 for sealing and melting. In use, the user only needs to pull the wrench 32 to drive the silicone head 36 to clamp the garbage bag against the heating component 37, completing the sealing and melting process. The operation is simple and effortless. After the wrench 32 is released, the first slider 34 automatically resets, eliminating the need for manual retraction. The flexibility of the silicone head 36 adapts to the surface of the garbage bag, working with the heating component 37 to achieve uniform heating, ensuring a firm seal and good airtightness, effectively preventing odor leakage.

[0040] In this embodiment, the heating assembly 37 includes a ceramic base and a heating wire. The heating wire is embedded in the ceramic base, and a portion of the ceramic base protrudes from the opening of the second cavity. When the silicone head 36 clamps the garbage bag against the ceramic base, the heating wire is energized to generate heat, which is conducted through the ceramic base to the surface of the garbage bag, causing it to melt and fuse, thus achieving sealing and fusion. The heating principle and control method of the heating assembly 37 are common knowledge in the art and will not be described in detail here.

[0041] In this embodiment, the first slider 34 is connected to the outer shell 31 by two first elastic members 35. Specifically, the first slider 34 has a first abutment portion protruding on the side near the inner wall of the first cavity, and two first connectors are arranged at intervals along the vertical direction on the first abutment portion; the inner wall of the first cavity has two corresponding second abutment portions protruding, and two second connectors are arranged at intervals along the vertical direction on the side of the second abutment portion facing the first abutment portion. The first elastic member 35 is a spring, and one end of each first elastic member 35 is sleeved on the corresponding first connector, and the other end is sleeved on the corresponding second connector.

[0042] In this embodiment, the wrench 32 is U-shaped, with the two side walls of the open end of the U-shape rotatably connected to the opposite sides of the outer shell 31. The cam 33 is fixedly connected to the rotating shaft of the wrench 32 and located in the first cavity. When the wrench 32 swings around the rotating shaft, it drives the cam 33 to rotate synchronously.

[0043] Specifically, the sealing mechanism 3 also includes a micro switch 310, which is disposed on the inner wall of the first cavity. A pressing part protrudes from the side of the first slider 34. When the first slider 34 moves to the pressing part and presses the micro switch 310, the heating component 37 starts heating. Through the cooperation of the micro switch 310 and the pressing part, the heating component 37 is automatically started. The user can trigger heating at the same time as sealing without additional operation, ensuring that the sealing and heating actions are completed synchronously. At the same time, it avoids the heating component from burning dry for a long time, improves the safety of use and reduces energy consumption.

[0044] In this embodiment, the micro switch 310 is installed on the inner wall of the first cavity facing the first slider 34 and is located between the two second abutment portions. The first abutment portion has a pressing portion protruding on the side facing the micro switch 310. When the first slider 34 moves to press the micro switch 310, the heating component 37 starts to start and the heating wire starts to heat.

[0045] More specifically, the sealing mechanism 3 also includes a second elastic element 38 and a second slider 39. The first slider 34 has a receiving groove on the side facing the opening, and the second slider 39 slides into the receiving groove. The second elastic element 38 is connected to the bottom of the receiving groove and the second slider 39. The silicone head 36 is connected to the end of the second slider 39 away from the second elastic element 38. When the silicone head 36 clamps the garbage bag with the heating component 37, the second elastic element 38 can absorb excess pressure to avoid rigid collisions that could cause the garbage bag to break or parts to be damaged. At the same time, the floating structure of the second slider 39 allows the silicone head 36 to adapt to changes in the thickness of the garbage bag surface, ensuring uniform clamping force and a more secure seal.

[0046] In this embodiment, two third connectors are arranged vertically at intervals on the side of the second slider 39 facing the first slider 34, and correspondingly, two fourth connectors are arranged vertically at intervals on the bottom of the storage groove; two second elastic members 38 are provided, with one end of each second elastic member 38 sleeved on the corresponding third connector and the other end sleeved on the corresponding fourth connector.

[0047] More specifically, the bottom surface of the intermediate frame 12 has a mounting groove, and the outer shell 31 is partially inserted into the mounting groove. The surface of the outer shell 31 has a protruding connecting part 3101, which is fixed to the bottom surface of the intermediate frame 12 by bolts. By inserting the outer shell 31 into the mounting groove, the sealing mechanism 3 and the intermediate frame 12 can form an embedded fit, which is compact and saves space. At the same time, the connecting part 3101 is fixed by bolts, which is convenient for disassembly and assembly, facilitates later maintenance or replacement of the sealing mechanism, and the connection is firm.

[0048] Specifically, the semi-automatic sealing and packaging trash can also include a button 5. Button 5 is installed on the outer surface of the middle frame 12 and is communicatively connected to the drive component 21. When button 5 is triggered, the drive component 21 can drive the two sealing doors 22 to open or close, and the monitoring signal of the second switch Hall 42 is blocked until the first switch Hall 41 detects that the top cover 13 is closed. By adding button 5, users can manually control the opening and closing of the sealing doors 22 as needed, facilitating daily cleaning or inspection of the inside of the can. Furthermore, button control and automatic control complement each other, improving the product's interactive flexibility and ease of use. In addition, blocking the monitoring signal of the second switch Hall 42 until the first switch Hall 41 detects that the top cover 13 is closed prevents the sealing doors 22 from being opened and immediately triggering the automatic closing logic when the user manually operates button 5, thus preventing the sealing doors 22 from remaining open and the user from performing operations such as sorting or inspecting the trash bags inside the can.

[0049] It should be noted that the trigger signal processing of button 5 and the linkage algorithm with the drive component 21 and the second switch Hall 42 are conventional technical means in this field, and will not be described in detail here.

[0050] Specifically, the top surface of the bin body 11 is provided with a snap-fit ​​component 6, which includes an insert plate 61 and a protrusion 62. The protrusion 62 is located on the side of the insert plate 61. Correspondingly, the bottom of the intermediate frame 12 is provided with a slot 1201, and the outer wall of the intermediate frame 12 is provided with a locking hole 1202 communicating with the slot 1201. The insert plate 61 is inserted into the slot 1201, and the protrusion 62 is engaged in the locking hole 1202. Through the cooperation of the insert plate 61 and the slot 1201 and the engagement of the protrusion 62 and the locking hole 1202, the bin body 11 and the intermediate frame 12 can be quickly assembled and disassembled. The structure is simple and the connection is reliable. Users only need to press the protrusion 62 to separate the two, which makes it easy to remove the sealed garbage bag or clean the inside of the bin body 11, thus improving the convenience of use.

[0051] In this embodiment, both the barrel body 11 and the middle frame 12 are rectangular. Except for the rotating connection side and the side opposite to the rotating connection side, the top surface of the barrel body 11 is provided with snap-fit ​​parts 6 on both sides. Correspondingly, the bottom of the middle frame 12 has two slots 1201 and two snap-fit ​​holes 1202.

[0052] Specifically, the bottom surface of the bin 11 is provided with multiple support feet 7 spaced circumferentially. These support feet 7 increase the stability and anti-slip properties of the bin when placed, preventing it from sliding or tipping over during use. Simultaneously, the support feet 7 lift the bottom of the bin 11 off the ground, facilitating ventilation and heat dissipation, and reducing the impact of ground moisture on the bin. The specific number of support feet 7 can be flexibly adjusted according to actual needs.

[0053] This invention also provides a method for using a semi-automatic sealing and packaging trash can, comprising: When you need to dispose of garbage, open the top cover 13 to dispose of the garbage, then close the top cover 13 and wait for the preset time. When it is necessary to pack the garbage, open the middle frame 12, manually operate the sealing mechanism 3 to seal and melt the garbage bag, then take out the sealed garbage bag and throw it away, then manually pull the new garbage bag down into the bottom of the bin 11, and finally close the middle frame 12.

[0054] Users only need to complete simple actions such as opening the top cover 13 to dispose of garbage, closing the top cover 13 and waiting for a preset time, opening the middle frame 12, manually operating the sealing mechanism 3, taking out the sealed garbage bag, pulling the new garbage bag, and closing the middle frame 12. The remaining sealing and bag placement actions are all completed automatically by the garbage bin, making operation convenient and labor-saving. At the same time, the entire process achieves odor isolation and avoids users directly contacting the garbage bag opening, improving hygiene.

[0055] The preset time is matched with the output power of the drive unit 211 and the travel distance of the moving block 217 to ensure that the two sealing doors 22 can complete the full action from opening to closing. In this embodiment, after the user closes the top cover 13, wait for about 8-10 seconds, and the two sealing doors 22 can complete the full action of opening and closing.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
