[0039] refer to Figures 1 to 8 The present invention provides a trash can, comprising a bin body 1, a drive mechanism 2, a support 3, a first gathering assembly 4, a second gathering assembly 5, and a heating element 6. The bin body 1 has a receiving groove 11 and a receiving cavity 12 spaced apart in the height direction. The receiving groove 11 is located below the receiving cavity 12, which is used to receive a trash bag. An opening 121 is provided on the inner edge of the receiving cavity 12 to allow the trash bag to extend out. The drive mechanism 2 is disposed within the receiving groove 11 along a first direction 17. The support 3 is disposed within the receiving groove 11 along a second direction 18 perpendicular to the first direction 17. The support 3 is connected to the drive mechanism 2, which drives the support 3. The first gathering component 4 and the second gathering component 5 are both disposed within the bracket 3. The bracket 3, driven by the drive mechanism 2, drives the first gathering component 4 and the second gathering component 5 to move along the first gathering component 17. The first gathering component 4 is connected to the drive mechanism 2, and the second gathering component 5 is connected to the first gathering component 4, thereby achieving synchronous rotation of the first gathering component 4 and the second gathering component 5. At least a portion of the first gathering component 4 and the second gathering component 5 are in contact to gather the garbage bag between the contact areas of the first gathering component 4 and the second gathering component 5. The heating element 6 is disposed within the first gathering component 4 or the second gathering component 5. The heating element 6 is used to melt and seal the garbage bag.

[0040] This application includes a drive mechanism 2 and a support 3. The first gathering component 4 and the second gathering component 5 are disposed within the support 3. The drive mechanism 2 can drive the first gathering component 4 and the second gathering component 5 to move along the first direction 17. The drive mechanism 2 is also connected to the first gathering component 4 in a transmission manner. The first gathering component 4 and the second gathering component 5 are connected in a transmission manner, so that the first gathering component 4 and the second gathering component 5 rotate along their own outer peripheral walls. As the support 3 moves along the first direction 17, the first gathering component 4 and the second gathering component 5 are driven to continuously move closer to the garbage bag, and can continuously gather the garbage bag between the contact areas of the first gathering component 4 and the second gathering component 5. Then, the heating element 6 continuously melts and seals the garbage bag. Therefore, in the process of garbage bag gathering, the first gathering component 4 and the second gathering component 5 move closer to the garbage bag and gather both sides of the garbage bag into the contact area of ​​the first gathering component 4 and the second gathering component 5. While gathering, heat sealing is carried out. During the gathering process, excessive wrinkles can be avoided at the opening of the garbage bag, making the thickness of the garbage bag opening more uniform. Moreover, the thickness of the garbage bag opening during heat sealing is much smaller than the thickness of the garbage bag opening after gathering in the prior art, which can make the heat sealing more thorough and uniform, thereby improving the sealing effect of the garbage bag and reducing the possibility of air leakage or seal cracking.

[0041] Specifically, the first gathering component 4 and the second gathering component 5 are connected only at the rear middle by a support.

[0042] Specifically, the first direction 17 is the width direction of the barrel 1, and the second direction 18 is the length direction of the barrel 1, or the first direction 17 is the length direction of the barrel 1, and the second direction 18 is the width direction of the barrel 1. In this embodiment, the first direction 17 is the width direction of the barrel 1, and the second direction 18 is the length direction of the barrel 1.

The push-out device 62 is spaced apart from the first contact area 41 in the height direction of the can body 1, and the push-out device 62 protrudes from the first contact area 41 in the direction close to the second contact area 51. Since there is a gap on both sides of the trash bag when it is closed, by providing the push-out device 62 to push against the trash bag, the gap on both sides after the trash bag is stuck together can be shortened, so that the trash bag can be tightly connected during the closing process, and the opening of the trash bag can be welded evenly and without leakage when it is melted and sealed, further improving the sealing performance of the trash bag opening.

[0047] Specifically, the ejector device 62 is positioned relative to the heating element 6 near the center of the barrel 1.

Specifically, there are two guards 96, which are located on opposite sides of the second ramp 93, so that the garbage bag opening can continue to move along the second ramp 93 and be cut off.

[0088] This application, by providing a first pushing ramp 9 and a second pushing ramp 92, is able to completely separate the garbage bag opening from the remaining bag body.

[0089] refer to Figure 7This application also includes a sensor 14 located within the receiving groove 11. The bracket 3 further includes a fourth bracket 34, one end of which is connected to the third bracket 33, and the other end of which is slidably connected to the side wall of the receiving groove 11. The fourth bracket 34 can move along the first direction 17 under the drive of the third bracket 33. The fourth bracket 34 is located below the third bracket 33. The sensor 14 is disposed on the fourth bracket 34. One end of the third bracket 33 is rotatably connected to the rear support block 82 via a rotating shaft, and the rotating shaft and the first transmission wheel 54 are coaxially arranged. The third bracket 33 and the second gathering assembly 5 can rotate around the rotating shaft. When there is a protrusion inside the garbage bag that obstructs the packaging of the garbage bag, the protrusion will cause the second gathering assembly 5 and the third bracket 33 to rotate around the rotating shaft in a direction away from the first gathering assembly 4. When the third bracket 33 rotates to contact the sensor 14, the sensor 14 will transmit a signal to make the garbage can sound an alarm.

[0090] Specifically, this application also includes a return spring 15, one end of which is connected to the side wall of the bin body 1, and the other end of which is connected to the other end of the third bracket 33. When the trash can sounds an alarm, the operator removes the protrusion so that the third bracket 33 and the second retracting assembly 5 are reset under the action of the return spring 15, restoring the normal operation of the trash can.

[0091] The trash can of this application also includes a controller 16, which is disposed on the can body 1. The controller 16 is electrically connected to the motor 211 and the sensor 14 respectively. The controller 16 is used to control the opening and closing of the motor 211.
