[0093] Specifically, the stretching mechanism 60 includes:

[0094] The pressure rod 61 is constructed as a rod-shaped structure arranged in the horizontal direction;

[0095] And a pressure rod driving assembly that drives the pressure rod 61 to move in the up and down directions.

[0096] The automated trash can provided in this embodiment uses a pressure rod 61 made of a rod-like structure arranged in a horizontal direction to press down the trash bag 90, thereby ensuring that a single press can press down the trash bag 90 as a whole in the width direction, with a more uniform pressure force and a high fault tolerance rate, and no centering positioning is required, thereby ensuring subsequent use.

[0097] Specifically, the stretching mechanism 60 further includes:

[0103] Specifically, the pressure rod yielding portion 23 divides the inner barrel 20 into at least two sub-barrel structures.

[0104] In the automatic trash can provided in this embodiment, the pressure rod 61 passes through the pressure rod yielding portion 23 when in motion, thereby pulling the trash bag 90 down from the opening of the trash can and passing it to the bottom of the inner trash can, and the trash bag 90 is squeezed between the sub-cylinder structures through the oppositely arranged sub-cylinder structures moving toward each other. The opposite movement of the sub-cylinder structures will be described below.

[0106] Specifically, the contour heat seal 22 is also provided around the edge contour of the sub-cylinder structure.

[0107] The automated trash can provided in this embodiment fuses the trash bags 90 squeezed between the sub-cylinder structures through the contour heat seal 22, so that the trash bags form a whole in the up and down directions.

[0108] Preferably, the bottom contour of the sub-cylinder structure is also provided with a contour heat seal 22, and the contour heat seal line around the inner barrel heat seals the film garbage bag to prevent water leakage due to improper sealing at the bottom of the film garbage bag.

[0114] Specifically, the inner barrel moving mechanism 40 includes:

[0115] A traction block 44 is arranged on the outer surface of the sub-cylinder structure;

[0116] A traction member 43, which pulls the traction block 44 to move under the action of traction force; and

[0117] The first motor 41 is fixedly arranged, and directly or indirectly drives the traction member 43 to move.

[0118] Preferably, the inner barrel moving mechanism 40 further includes an inner barrel transmission belt 42, the first motor 41 drives the inner barrel transmission belt 42 to move, and the inner barrel transmission belt 42 drives the traction member 43 to move.

[0121] As a variation, the movement of the heat sealing blade head 25 can also be achieved by a telescopic push rod, a crank connecting rod or other structural forms, which will not be described in detail here.

[0122] Preferably, a heat sealing blade head accommodating cavity 21 is also provided below the barrel mouth of the inner barrel 20, and the heat sealing blade head accommodating cavity 21 is suitable for accommodating the heat sealing blade head 25, and when not in use, the heat sealing blade head 25 is hidden in the heat sealing blade head accommodating cavity 21 to avoid hot melting of the garbage bag.

[0123] Preferably, the automated trash can is also provided with a height sensor. Through the induction of the trash height sensor in the trash can, when the trash in the trash can reaches a certain amount, the heat sealing cutter head in the inner barrel and the heat sealing cutter head in the placement cavity move relative to each other to perform sealing, thereby completing the packaging and sealing of the trash bag.

[0124] Specifically, the length of the bag placing end 31 is greater than the length of the projection of the contour heat seal 22 on the bag placing end 31. Therefore, after the contour heat seal 22 contacts the garbage bag 90, the contour heat seal 22 is suitable for melting a local area of ​​the garbage bag 90, and the garbage bag 90 after melting retains a corner connection part 91 for connecting the garbage bags 90 on both sides between the bag placing end 31 and the bag receiving end 32.

[0126] After taking away the packaged garbage, the stretching mechanism resets the pressure rod. At the same time, the conveying motor at the bag collecting end starts synchronously, and the excess film scraps are collected at the bag collecting end. When the pressure rod is completely reset, the conveying motor at the bag collecting end continues to drive the film garbage bag to move, preparing for the next intact film garbage bag to enter the next bag changing action. After the film garbage bag moves into place, the pressure rod is pressed down to complete the second bag changing action, and then the above action is continued. This continuous action can realize automatic bag changing, bagging, heat sealing and packaging of the garbage bin, thereby realizing the intelligence of the garbage bin.

[0127] Specifically, the automated trash can further includes: a sensor 12, wherein the sensor 12 is adapted to control the opening and closing of the trash can cover 11 according to a sensing state.

[0128] Specifically, the automated trash can also includes:

[0129] The outer barrel is arranged outside the inner barrel 20, and the bag receiving and placing mechanism 30 and the stretching mechanism 60 are arranged in the space between the inner barrel 20 and the outer barrel.

[0130] As a preferred implementation form, the first motor 41, the second motor 62, the pressure rod guide 64, the bag storage mechanism 30, the pressure plate guide 52 and other structures can be directly or indirectly arranged on the outer barrel to achieve fixation. This embodiment does not record the specific fixing form of the above-mentioned structure in more detail, but for ordinary technicians in the field, it can be achieved through conventional means and will not be repeated here.

[0131] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
