Description

Technical Field

[0001] The present invention belongs to the technical field of garbage collection devices, and in particular relates to a garbage compression mechanism and an intelligent garbage can. Background Art

[0002] In the current use of trash cans, when paper, packaging bags and other garbage are put in, due to the relatively large volume of this type of garbage, it is easy to cause the trash can to be empty, which will cause obstacles to the subsequent garbage disposal. The setting of a garbage compression mechanism can compress the garbage in the garbage bag, facilitate the subsequent garbage disposal, and increase the capacity of the garbage bag.

[0003] For example, the invention patent application with publication number CN112407684A discloses a garbage bag packing mechanism with a compression function, in which a garbage compression mechanism is provided in the bag collecting pressure rod and the bag collecting sealing pressure rod, which compresses the compressible garbage in the garbage bag while collecting and sealing the bag, thereby reducing the volume of the packed garbage bag. This structure can only compress the garbage when collecting the garbage bag, and cannot increase the garbage holding capacity of the garbage bag; another example is the utility model patent with publication number CN214166083U, which discloses a vacuum suction device for a garbage can, in which a bucket cover exhaust mechanism and a bucket exhaust mechanism are provided in the garbage can, which can exhaust in different directions during operation to realize the laying of the garbage bag and the compression of the garbage. However, the pressure value of the garbage compressed by gas is limited, and it is difficult to effectively compress the garbage when the garbage in the bag is hard.

[0004] Therefore, designing a garbage compression mechanism that can compress garbage during the use of the garbage bin and can achieve efficient garbage compression to increase the capacity of the garbage bag can effectively improve the user experience. Summary of the Invention

DETAILED DESCRIPTION

[0042] The technical solution of the present invention is described in detail below through specific embodiments.

[0043] Example 1

[0044] like Figure 1-7 As shown in the figure, schematic diagrams of the overall and local structures of the garbage compression mechanism in Example 1 are respectively given.

[0045] The garbage compression mechanism 2 is located inside the barrel body 1 of the trash can, and includes a garbage compression module, a driving device that drives the garbage compression module to move up and down inside the barrel body 1, and a transmission device connecting the garbage compression module and the driving device; the garbage compression module includes a compression cover plate 3, and a motion guide groove 4 is provided on the inner wall of the barrel body 1. When the garbage compression module moves up and down inside the barrel body 1, the compression cover plate 3 moves along the motion guide groove 4.

[0046] The transmission device includes a transmission gear 5, a screw rod 6 and a screw rod flange 7. The transmission gear 5 and the screw rod 6 are sequentially connected to the driving device. The screw rod flange 7 is installed on the screw rod 6. A rotating shaft 14 is provided on the screw rod flange 7. The compression cover plate 3 is rotatably installed on the rotating shaft 14.

[0047] In the present invention, the transmission device is not limited to the above-mentioned form. In other embodiments, the transmission device may also be a combination of a motor and a rack, a hydraulic rod, an electric push rod, a motor and a transmission belt, etc.

[0048] Specifically, a screw groove 8 is provided on the inner wall of the barrel body 1, and the screw 6 is installed in the screw groove 8, and the screw groove 8 is connected to the motion guide groove 4; the compression cover plate 3 can be flipped and retracted relative to the barrel body 1, and the compression cover plate 3 includes a head end and a tail end arranged opposite to each other, and a connecting rod 9 is fixedly installed on the head end, and the end of the connecting rod 9 away from the head end is rotatably sleeved on the rotating shaft 14; an inclination angle α is provided between the connecting rod 9 and the compression cover plate 3, α = 45°-135°, preferably α = 90°, that is, the connecting rod 9 is arranged vertically to the compression cover plate 3; the head end of the compression cover plate 3 is located in the motion guide groove 4, and the tail end is a free end.

[0049] In a specific embodiment, the number of compression cover plates 3 is two, and the driving device is a first motor 10. The output shaft of the first motor 10 is connected to a driving gear 11, and the driving gear 11 is meshed with the transmission gear 5. Each compression cover plate 3 is connected through a set of driving devices and transmission devices.

[0050] In a specific embodiment, there are two screw rods 6 , which are respectively located on both sides of the compression cover plate 3 to drive the movement of the compression cover plate 3 .

[0051] In other embodiments, the compression cover plate 3 and the screw rod 6 can also be set to other numbers according to the specific application scenario. For example, the screw rod 6 can be set to 4, which are respectively located at the four corners of the barrel body 1.

[0052] A first trash inlet 12 is provided within the barrel body 1, and a protrusion 13 is provided at the head end of the compression cover plate 3 perpendicular to the connecting rod 9. This protrusion 13 forms a trash bag securing mechanism. When using a breakpoint trash bag, the trash bag is laid into the barrel body 1 from the first trash inlet 12 and sleeved onto the outside of the compression cover plate 3. The opening of the trash bag is secured to the protrusion 13 to prevent the trash bag from falling off during use. When using a non-breakpoint trash bag, the trash can can be equipped with an automatic trash bag laying mechanism to lay the trash bag between the two compression cover plates 3 within the first trash inlet 12.

[0053] The two compression cover plates 3 are located inside the barrel body 1. When the two compression cover plates 3 are opened, the first garbage delivery port 12 is fully exposed. At this time, garbage can be delivered normally. When the garbage needs to be compressed, the first motor 10 is started, driving the screw 6 to rotate, and the screw flange 7 moves downward on the screw 6, and drives the connecting rod 9 downward, thereby driving the head end of the compression cover plate 3 to flip and shrink downward. At this time, the compression cover plate 3 moves downward as a whole to compress the garbage in the garbage bag. When the two compression cover plates 3 flip and shrink close together, they can completely cover the first garbage delivery port 12, and the garbage bag is further compressed downward under the drive of the first motor 10, thereby achieving garbage compression. After compression is completed, the first motor 10 is reversed, and the screw 6, screw flange 7 and compression cover plate 3 all move in the opposite direction. The garbage bag is unfolded, and the garbage can be delivered normally again.

[0054] The garbage compression mechanism of the present invention utilizes a compression cover that flips open. It includes a motor, gears, and a compression cover. The gear transmission imparts excellent quietness to the mechanism. The motor drives the driven gear on the compression cover via the active gear, driving the compression cover to rotate, thus resolving the issues of the compression cover's smooth opening and slow opening speed. The garbage compression mechanism of the present invention also simplifies assembly, thereby improving the reliability of the compression cover's opening and closing. Furthermore, the gear transmission's ability to rotate in both directions allows for the left and right opening and closing of the dual covers. The garbage compression mechanism of the present invention can increase the capacity of a trash can and effectively reduce the frequency of bag changes.

[0055] Furthermore, when the garbage compression mechanism 2 is implemented in a smart trash can, an automatic garbage bag placement mechanism can be incorporated. In this case, the garbage bag is placed between the two compression covers 3 of the garbage compression mechanism 2. When the garbage compression mechanism 2 is activated, the first motor 10 rotates, driving the screw flange 7 downward, closing the compression covers 3 and compressing the garbage bag downward, thereby compressing the garbage. After compression is complete, the first motor 10 reverses and raises the compression covers 3, allowing garbage to be placed normally again. Furthermore, a garbage bag sealing mechanism can be incorporated into the smart trash can to automatically seal and pack the garbage bags.

[0056] Example 2

[0057] like Figure 8-16 As shown, schematic diagrams of the overall and local structures of the garbage compression mechanism in Example 2 are respectively given.

[0058] The trash can's body 1 comprises an outer barrel 101 and an inner barrel 102. The trash compression mechanism 2 is installed within the inner barrel 102 and nested within the outer barrel 101. The trash compression mechanism 2 includes a trash compression module, a drive device that moves the module up and down within the body 1, and a transmission device connecting the module and the drive device. The trash compression module includes a trash bag assembly and a compression cover 3 that can translate and retract relative to the body 1.

[0059] The driving device is a first motor 10, the output shaft of which is connected to a driving gear 11, which is meshed with the transmission gear 5. There are two first motors 10, one at each end of the inner barrel 102.

[0060] The transmission device includes a transmission gear 5 , a screw rod 6 and a screw rod flange 7 . The transmission gear 5 and the screw rod 6 are sequentially connected to the driving gear 11 , and the screw rod flange 7 is installed on the screw rod 6 .

[0061] In the present invention, the transmission device is not limited to the above-mentioned form. In other embodiments, the transmission device may also be a combination of a motor and a rack, a hydraulic rod, an electric push rod, a motor and a transmission belt, etc.

[0062] Each first motor 10 is connected to the garbage compression module through a set of transmission devices. In the two sets of transmission devices, the two screw rods 6 are connected by a screw rod connecting plate 15, and the two transmission gears 5 are connected by a gear connecting plate 16. The screw rod connecting plate 15 and the gear connecting plate 16 can make the structure of the garbage compression mechanism 2 more stable, and ensure that the two ends of the garbage compression module move synchronously when the driving device drives the garbage compression module to move up and down in the barrel body 1, thereby realizing synchronous and smooth compression of the garbage in the garbage bag.

[0063] A mounting plate 17 is fixedly connected to the screw flange 7 , a translation drive mechanism is mounted on the mounting plate 17 , the compression cover plate 3 is connected to the translation drive mechanism, and the compression cover plate 3 can be translated and retracted relative to the barrel body 1 .

[0064] The translation drive mechanism includes a second motor 18, a synchronous belt 19, and a drive rod 20; the second motor 18 is connected to the synchronous belt 19 through gears, and the drive rod 20 is provided with meshing teeth, and the drive rod 20 is meshed with the synchronous belt 19 through meshing teeth; one end of the compression cover plate 3 is rotatably connected to the mounting plate 17 through a first hinge shaft 21, and the other end is rotatably connected to the drive rod 20 through a second hinge shaft 22.

[0065] In other embodiments, the translation drive mechanism may also be a combination of a motor and a rack, a hydraulic rod, an electric push rod, a transmission belt, etc., to drive the compression cover plate 3 to translate, open or fold.

[0066] A second garbage inlet 24 is provided on the mounting plate 17 , and the second garbage inlet 24 is communicated with the first garbage inlet 12 provided on the barrel body 1 .

[0067] Two sets of compression cover plates 3 are provided, one at each end of the second trash inlet 24. In this second embodiment, each set of compression cover plates 3 includes two folding plates (in other embodiments, the number of folding plates may be three or more). The two folding plates are rotatably connected via a third hinge 23. Movement of the drive rod 20 drives the two folding plates to rotate relative to the first hinge 21, the second hinge 22, and the third hinge 23, thereby opening or folding the plates to expose or cover the second trash inlet 24.

[0068] A guide rod 25 is provided on the inner wall of the inner barrel 102, and the guide rod 25 is slidably connected to the mounting plate 17 through a guide seat 26. In this embodiment 2, the number of the guide rods 25 is 4, which are respectively located at the 4 edge positions of the mounting plate 17.

[0069] Below the synchronous belt 19 on the mounting plate 17 , photoelectric sensors 27 are provided at the starting and ending positions of the driving rod 20 , which can sense the running position of the driving rod 20 and ensure the accuracy of the compression cover 3 during operation.

[0070] In this second embodiment, the garbage bag assembly is a garbage box 30, which can hold non-breakpoint garbage bags. The garbage box 30 is mounted on the mounting plate 17 via a garbage box mounting bracket 31. In other embodiments, the garbage bag assembly can also be a garbage bag fixing mechanism adapted for ordinary breakpoint garbage bags to facilitate the laying of garbage bags.

[0071] An outer barrel cover 28 is provided above the outer barrel 101 and on top of the trash box 30, covering the inner barrel 102 and the trash box 30 inside the outer barrel 101. A protective shell 32 is provided on the mounting plate 17 outside the translation drive mechanism to protect the translation drive mechanism.

[0072] When the garbage compression mechanism 2 in this embodiment 2 is working, first the second motor 18 is started, driving the synchronous belt 19 to rotate, and the two driving rods 20 drive the compression cover 3 to open under the action of the synchronous belt 19, driving the garbage bag to gather toward the middle of the second garbage delivery port 24, covering the second garbage delivery port 24; then the first motor 10 is started, the screw 6 rotates, and under the action of the screw flange 7, the mounting plate 17 and the garbage compression module are driven downward, and the downward pressure of the compression cover 3 compresses the garbage in the garbage bag; after compression is completed, the first motor 10 starts to reverse, the position of the garbage compression module rises, and then the second motor 18 reverses, and the driving rod 20 drives the compression cover 3 to fold to expose the second garbage delivery port 24. At this time, garbage can be put into the garbage bin normally again.

[0073] At the same time, a hot melt sealing mechanism 29 is provided on the driving rod 20. The hot melt sealing mechanism 29 is embedded in the side wall of the driving rod 20. When the garbage bag is filled and needs to be sealed, the two sets of compression cover plates 3 pull the garbage bag toward the middle of the second garbage delivery port 24, and the hot melt sealing mechanism 29 is activated to hot melt seal the garbage bag.

[0074] In this embodiment 2, the driving rod 20 can also serve as a packing rod, which can gather the garbage bags to the middle of the second garbage inlet 24 during packing and seal them using the hot melt sealing mechanism 29; in other embodiments, an auxiliary rod can also be set at the second garbage inlet 24 to form a packing mechanism with three, four or more rods to pack and hot melt seal the garbage bags; at the same time, in other embodiments, the hot melt sealing mechanism 29 may not be set on the driving rod 20, and an additional garbage bag packing and hot melt sealing mechanism can be set in the garbage compression mechanism 2 to pack and hot melt seal the garbage bags.

[0075] In addition, when the garbage compression mechanism 2 of the present invention is applied in the smart trash can, an automatic garbage bag laying mechanism can be provided in the smart trash can to automatically lay the garbage bags in the trash box.

[0076] In the present invention, the automatic laying mechanism for garbage bags, the packaging and hot-melt sealing mechanism for garbage bags, etc. can adopt existing technologies, such as the technical solutions disclosed in CN116040150A, CN222808676U, CN221342356U, CN220975371U, CN220316103U, CN218950083U, etc.

[0077] The above are only preferred embodiments of the present invention and are not intended to limit the invention.
