Description

Technical Field

[0001] This utility model relates to the field of trash can technology, and in particular to an anti-tipping trash can with a pneumatic adsorption plate at the bottom. Background Technology

[0002] Trash cans, as essential cleaning tools in daily life, are widely used in homes, offices, and public places. However, traditional trash cans often suffer from problems such as a high center of gravity and limited bottom contact area, resulting in poor stability. In actual use, especially when placed in high-traffic areas such as corridors and kitchens, trash cans are easily tipped over due to accidental kicks or impacts. This not only causes trash to scatter everywhere, polluting the environment and increasing the cleaning burden, but may even damage the can's structure due to tipping.

[0003] To address this issue, existing technologies typically employ methods such as adding counterweights to lower the center of gravity or attaching double-sided tape to the bottom for fixation. However, adding counterweights significantly increases the overall weight of the trash can, making daily handling and cleaning inconvenient; while using adhesive tape for fixation restricts the trash can's movement and leaves residue that is difficult to clean, affecting its appearance. Therefore, how to ensure the trash can is stable and prevents tipping while also enabling convenient movement and repositioning has become a pressing technical challenge for those skilled in the art.

[0004] Therefore, this utility model proposes an anti-tipping trash can with a pneumatic adsorption plate at the bottom to overcome the shortcomings of the prior art. Utility Model Content

The limiting plate is used to rotate around the rotating column to above the pressing plate to abut and restrict the upward reset of the pressing plate.

[0010] Preferably, the device further includes a bucket lid, a sleeve, and a rotating shaft. The rotating shaft is fixedly connected to the top edge of the upper bucket, the sleeve is rotatably fitted onto the outer surface of the rotating shaft, and one edge of the bucket lid is fixedly connected to the outer wall of the sleeve.

[0027] 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.

[0028] Reference Figures 1-5 This utility model provides an anti-tipping trash can with a pneumatic adsorption plate at the bottom, which aims to solve the problems of poor placement stability of trash cans that are prone to tipping over due to collisions and low space utilization due to the difficulty of fitting trash bags properly due to air resistance when inserting them.

[0029] Specifically, it includes a lower bin 1 and an upper bin 2 fitted above the lower bin 1. The lower bin 1 serves as the basic support component of the overall device, used to contain garbage and provide the main structural strength. A sleeve box 3 is fixedly connected to the bottom of the side wall of the lower bin 1. The sleeve box 3 serves as the installation carrier for functional components. Its fixing method can be welding or integral injection molding to ensure the stability of the connection. A bin lid 11 is rotatably connected to the top opening of the upper bin 2. The bin lid 11 is used to seal the internal space of the upper bin 2 to block odors.

[0030] It also includes an adsorption mechanism 5 and a limiting assembly 4. The adsorption mechanism 5 has a piston 501, a suction cup 502, an air inlet 503, a pressing plate 504, a telescopic column 505, a first spring 506, and a push block 507. The piston 501 is fixedly installed inside the casing 3. The piston 501 has a hollow cylindrical structure to provide a cavity for changes in internal air pressure. The suction cup 502 is connected to the bottom of the piston 501 and extends to the bottom of the casing 3. The bottom plane of the suction cup 502 is used to form a vacuum adsorption contact with the ground. The air inlet 503 is connected to the lower end of the side wall of the piston 501 to introduce air during reset. The push block 507 is slidably sealed to the piston. The inner cavity of 501, the outer peripheral wall of push block 507 and the inner wall of piston 501 are tightly fitted to ensure airtightness. The bottom end of telescopic column 505 is fixedly connected to the top surface of push block 507. The top end of telescopic column 505 extends vertically upward and passes through the top opening of piston 501 and is fixedly connected to the bottom surface of pressing plate 504. Pressing plate 504 serves as a force-bearing platform for the user to apply downward pressure. First spring 506 is sleeved on the outer surface of telescopic column 505, and the two ends of first spring 506 elastically abut against the bottom surface of pressing plate 504 and the top surface of piston 501, respectively. First spring 506 is used to provide upward restoring elastic force when pressing plate 504 loses external force restriction.

[0031] The limiting component 4 is provided with a fixed plate 401, a limiting plate 402, and a rotating column 403. The fixed plate 401 is fixedly connected to the top plane of the sleeve 3, the rotating column 403 is rotatably connected to the top of the fixed plate 401, and the limiting plate 402 is fixedly connected to the top of the rotating column 403. In the assembled state, the limiting plate 402 can rotate horizontally around the axis of the rotating column 403. When the pressing plate 504 is pressed down to the lowest position, so that a negative pressure is formed inside the suction cup 502 to adsorb the ground, the limiting plate 402 rotates to the top of the pressing plate 504 and abuts against the pressing plate 504 to limit the upward reset of the pressing plate 504. This rotating snap-fit ​​structure ensures that the suction cup 502 can remain in the negative pressure adsorption state for a long time, thereby preventing the trash can from tipping over. When it is necessary to move the trash can, the limiting plate 402 is rotated in the opposite direction to move it away from the top of the pressing plate 504, and the first spring 506 pushes the pressing plate 504 to reset, thereby releasing the adsorption.

[0032] As a preferred embodiment, in order to solve the air resistance problem when the garbage bag is inserted, an air outlet 10 is provided at the bottom of the side wall of the lower bin 1. The air outlet 10 penetrates the side wall of the lower bin 1. When the upper bin 2 is inserted into the lower bin 1, the upper bin 2 compresses the air in the lower bin 1 like a piston. The air outlet 10 is used to quickly discharge the air between the two bins, thereby using the negative pressure of the airflow to make the garbage bag stick tightly to the bin wall.

[0033] As another preferred embodiment, in order to realize the automatic flipping and opening of the lid, the anti-tipping trash can also include a lid 11, a sleeve 6, a torsion spring 7 and a rotating shaft 8. The rotating shaft 8 is fixedly connected to the top edge of the upper bucket 2. The sleeve 6 is rotatably sleeved on the outer surface of the rotating shaft 8. One side edge of the lid 11 is fixedly connected to the outer wall of the sleeve 6. The torsion spring 7 is sleeved on the outer surface of the rotating shaft 8, and the two ends of the torsion spring 7 are elastically connected to the upper bucket 2 and the lid 11 respectively. The torsion spring 7 continuously applies a torque to make the lid 11 flip upward.

[0034] In another preferred embodiment, in order to achieve the self-locking and unlocking of the lid by pressing, the anti-tipping trash can also includes a pressing and fastening mechanism 9. The pressing and fastening mechanism 9 is disposed between the upper bin 2 and the opening end of the lid 11. The pressing and fastening mechanism 9 includes a support column 904, an extension column 902, a semi-cone 901 and an elliptical ring 903. The support column 904 is vertically fixed to the top edge of the upper bin 2. The extension column 902 is coaxially fixed to the top of the support column 904. The semi-cone 901 is fixedly connected to the top of the extension column 902. The elliptical ring 903 is movably sleeved on the outer surface of the extension column 902 and located between the support column 904 and the semi-cone 901. The elliptical ring 903 can slide up and down along the extension column 902.

[0035] The pressing and fastening mechanism 9 also includes a pressing post 907, a latch 905, and a second spring 906. The pressing post 907 is fixedly connected to the bottom surface of the lid 11 away from the rotating shaft 8. An installation groove is provided inside the pressing post 907, and the latch 905 is slidably installed in this groove. The second spring 906 connects the latch 905 to the inner wall of the installation groove. Under the action of the second spring 906, the latch 905 tends to extend outwards. The latch 905 is used to close the lid 11 when pressed down. The force retracts and slides over the outer edge of the semi-cone 901, and then pops out under the action of the second spring 906 and locks onto the bottom plane of the semi-cone 901 to lock the lid 11. When the lid 11 is pressed open again, the latch 905 moves downward and hooks the elliptical ring 903 to slide upward along the extension post 902. The inclined surface of the elliptical ring 903 guides the latch 905 to slide outward to overcome the blocking range of the semi-cone 901, thereby unlocking and popping open the lid 11 under the action of the torsion spring 7.

[0036] Working principle: This device adopts a double-layer bin-fit design, which automatically adsorbs garbage bags through air pressure; at the same time, the bin lid 11 can be opened and closed freely with the help of the pressing and fastening mechanism 9; in addition, the suction cup 502 of the adsorption mechanism 5 is used to firmly fix it to the ground, thereby achieving a stable anti-tipping effect.

[0037] The bottom of the lower bin 1 is equipped with an air outlet 10. When the upper bin 2 is fitted onto the lower bin 1, it automatically absorbs the garbage bag through air pressure. The upper bin 2 is equipped with a rotating shaft 8, on which a torsion spring 7 is mounted. The upper bin 2 and the bin lid 11 are connected by a sleeve 6, which is fitted onto the rotating shaft 8, thereby enabling the bin lid 11 to freely flip. One end of the bin lid 11 is equipped with a pressing post 907, which cooperates with the pressing and fastening mechanism 9 on the upper bin 2 to enable the bin lid 11 to be freely fastened and opened. The support post 904 is connected to the extension post. 902, the elliptical ring 903 is fitted onto the extension post 902; when the pressing post 907 is pressed, the clamping force causes the tenon 905 to contact the semi-cone 901, the second spring 906 retracts inward, the tenon 905 locks the semi-cone 901, and the bucket lid 11 is fastened; when the pressing post 907 is pressed again, the tenon 905 locks the elliptical ring 903, and drives the elliptical ring 903 to move upward along the extension post 902, and slides over the semi-cone 901 with the help of the inclined surface of the elliptical ring 903, so that the bucket lid 11 is opened.

[0038] The bottom of the lower bin 1 is also equipped with an adsorption mechanism 5, in which the piston 501 is connected to the suction cup 502; the two ends of the telescopic column 505 are fixedly connected to the push block 507 and the pressing plate 504 respectively; when the pressing plate 504 is pressed, the telescopic column 505 drives the push block 507 to move downward in the piston 501, and uses air pressure to discharge the gas in the piston 501, so that it is firmly adsorbed to the ground; at this time, the limiting component 4 is used for limiting and fixing, the fixing plate 401 is fixed on the sleeve 3, and the two ends of the rotating column 403 are rotatably connected to the fixing plate 401 and the limiting plate 402 respectively; rotating the limiting plate 402, the pressing plate 504 is locked, so that it is firmly adsorbed to the ground; when it is necessary to move the trash can, continue to rotate the limiting plate 402 to move it away from the pressing plate 504, and with the help of the rebound force of the first spring 506, the telescopic column 505 and the push block 507 are reset, and the gas enters from the air inlet 503. At this time, the adsorption force between the suction cup 502 and the ground is weakened, thereby achieving the purpose of moving.

[0039] All electrical components mentioned in this document are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions, and existing publicly available power connection technologies are not described in detail here. The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
