Description

Technical Field

[0001] This invention relates to the technical field of trash cans, and particularly to a trash can. Background Technology

[0002] In existing trash cans, when packing trash bags, a mechanical device is needed to first gather the bag opening to a preset fixed area at the top of the trash can. Then, a heat-sealing device installed in a fixed position heat-seals the bag opening. After gathering, the bag opening is prone to excessive wrinkles, resulting in a thicker and unevenly thicker bag opening. This causes the heat-sealing device to be unable to heat and seal the bag opening evenly and thoroughly, resulting in a poor sealing effect of the trash bag, which can easily lead to air leakage or cracking of the seal. Summary of the Invention

[0003] Therefore, it is necessary to provide a trash can to solve the above-mentioned technical problems.

[0004] A trash can, the trash can comprising:

[0005] The drive mechanism is set along the first direction;

[0006] A bracket is provided along a second direction perpendicular to the first direction. The bracket is connected to the drive mechanism, which is used to drive the bracket to reciprocate along the first direction.

[0007] A first gathering component and a second gathering component are both mounted on the bracket. The bracket, driven by the driving mechanism, moves the first gathering component and the second gathering component along the first direction. The first gathering component is connected to the driving mechanism, and the second gathering component is connected to the first gathering component, thereby achieving synchronous rotation of the first gathering component and the second gathering component. At least a portion of the first gathering component and the second gathering component are in contact to gather the garbage bag between the contact areas of the first gathering component and the second gathering component.

[0008] A heating element is disposed within the first or second gathering assembly, and the heating element is used to melt and seal the garbage bag.

[0009] Optionally, the driving mechanism includes a driving component and a transmission component, both of which are arranged along the first direction. The bracket is connected to the driving component, and the driving component is used to drive the bracket to reciprocate along the first direction. The transmission component is partially disposed within the bracket and is drively connected to the driving component and to the first gathering component.

[0010] Optionally, the drive assembly includes a motor, a lead screw, and a lead screw nut. The motor is connected to the lead screw, the lead screw nut is threadedly connected to the lead screw, and the bracket is connected to the lead screw nut. The motor drives the lead screw to rotate, thereby causing the lead screw nut to reciprocate along the lead screw. The lead screw nut causes the bracket to move along the first direction.

[0011] Optionally, the transmission assembly includes a turbine and a transmission worm gear. The transmission worm gear is connected to the motor, and the turbine is sleeved on the transmission worm gear. The motor is used to drive the transmission worm gear to rotate, thereby driving the turbine to rotate. The turbine is disposed in the bracket, and the bracket is used to drive the turbine to reciprocate along the transmission worm gear. The turbine is also connected to the first retracting assembly.

[0012] Optionally, it also includes a timing pulley assembly, which is disposed within the bracket. The timing pulley assembly includes a first timing pulley, a second timing pulley, and a timing belt. The first timing pulley and the second timing pulley are spaced apart within the bracket. The first timing pulley meshes with the turbine, and the second timing pulley is driven to the first gathering assembly. The turbine drives the first timing pulley to rotate, and the timing belt is sleeved on the first timing pulley and the second timing pulley to achieve synchronous rotation of the first timing pulley and the second timing pulley.

[0013] Optionally, the first gathering component includes a first drive wheel assembly and a first transmission belt. The first drive wheel assembly is connected to the second synchronous pulley. The first transmission belt is sleeved on the first drive wheel assembly and moves along the outer peripheral wall of the first drive wheel assembly under the drive of the first drive wheel assembly.

[0014] Optionally, the second gathering component includes a second drive wheel assembly and a second transmission belt. The second drive wheel assembly is connected to the first drive wheel assembly. The second transmission belt is sleeved on the second drive wheel assembly. The second transmission belt moves along the outer peripheral wall of the second drive wheel assembly under the drive of the second drive wheel assembly. At least a portion of the area between the first transmission belt and the second transmission belt is in contact.

[0015] Optionally, the trash can further includes a first pushing ramp, which is disposed within the second gathering assembly. The first pushing ramp is spaced apart from the heating element. The first pushing ramp has a first inclined surface, which faces the heating element. The first pushing ramp can move along the first direction with the support. The first inclined surface is used to separate the molten trash bag opening from the remaining trash bag body.

[0016] Optionally, the trash can further includes a second pushing ramp, which is spaced apart from the first pushing ramp. The second pushing ramp has a second inclined surface, which faces the first pushing ramp and is parallel to the first inclined surface. The second inclined surface and the first inclined surface cooperate to achieve complete separation of the trash bag opening and the remaining trash bag body after melting and sealing.

[0017] Optionally, the trash can further includes a push-out device, which is disposed within the bracket and protrudes from the first gathering component. The push-out device is used to push against the opening of the trash bag to eliminate the gap between the two sides of the trash bag.

[0018] This application incorporates a drive mechanism and a support frame. The first and second gathering components are housed within the support frame. The drive mechanism enables the first and second gathering components to move along a first direction. The drive mechanism is also connected to the first gathering component via a transmission connection. This transmission connection allows the first and second gathering components to rotate along their outer peripheral walls. As the support frame moves along the first direction, the first and second gathering components continuously move closer to the garbage bag, continuously gathering the garbage bag between the contact areas of the first and second gathering components. Then, a heating element continuously melts and seals the garbage bag. Therefore, in the process of garbage bag folding, the first and second folding components of this application move closer to the garbage bag and fold both sides of the garbage bag into the contact area of ​​the first and second folding components, while simultaneously folding and heat-sealing. During folding, excessive wrinkles are avoided at the opening of the garbage bag, resulting in a more uniform thickness at the opening. Furthermore, the thickness of the garbage bag opening during heat-sealing is much less than the thickness of the garbage bag opening after folding in the prior art, allowing for more thorough and uniform heat-sealing. This improves the sealing effect of the garbage bag and reduces the possibility of air leakage or seal cracking. Attached Figure Description

[0041] refer to Figures 1 to 8 This invention provides a trash can, comprising a can 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 interior of the can body 1 is provided with 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 hold 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 to reciprocate along the first direction 17. The first gathering component 4 and the second gathering component 5 are both disposed within the bracket 3. Under the drive of the drive mechanism 2, the bracket 3 drives the first gathering component 4 and the second gathering component 5 to move along the first direction 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.

[0042] 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.

[0043] Specifically, the first gathering component 4 and the second gathering component 5 are connected only at the rear middle by a support.

[0044] 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 are gaps 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 gaps on both sides of the trash bag 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.

[0059] The transmission assembly 22 includes a turbine 221 and a transmission worm 222. The transmission worm 222 is connected to the transmission unit 212. The turbine 221 is sleeved on the transmission worm 222. The motor 211 drives the transmission worm 222 to rotate through the transmission unit 212, thereby driving the turbine 221 to rotate. The turbine 221 is set in the first bracket 31. The bracket 3 is used to drive the turbine 221 to reciprocate along the transmission worm 222. The turbine 221 is also connected to the first gathering assembly 4.

The inclusion of the first bearing 223 and the second bearing 224 ensures smooth rotation of the turbine 222.

[0066] This application uses a motor 211 to drive a lead screw 213 to rotate, thereby causing the lead screw nut 214, bracket 3, and turbine 221 to move along the first direction 17. The motor 213 is also connected to a transmission worm gear 222. The motor 211 drives the transmission worm gear 222 to rotate, thereby driving the turbine 221 to rotate, realizing the reciprocating movement and rotation of the turbine 221, thus approaching and collecting the garbage bag.

[0086] The trash can of this application also includes a first pushing ramp 9, which is disposed on the side of the mounting part 61 facing the first gathering component 4. The first pushing ramp 9 is spaced apart from the heating element 6, and the first pushing ramp 9 is located on the side of the heating element away from the center of the can body 1. The first pushing ramp 9 has two first inclined surfaces 91 forming a blade, which are disposed facing the heating element 6. As the bracket 3 moves along the first direction 17, the first inclined surface 91 is used to initially separate the molten trash bag opening from the remaining trash bag.

[0087] The trash can of this application also includes a second pushing ramp 92, which is disposed on the back support block 82. The second pushing ramp 92 is spaced apart from the first pushing ramp 9 and is located on the side of the first pushing ramp 9 away from the heating element 6. The second pushing ramp 92 has a second inclined surface 93, and the second inclined surface 93 is parallel to the first inclined surface 91. When the first inclined surface 91 fails to completely separate the trash bag opening, the second inclined surface 93 continues to work to continue to separate the trash bag openings that are stuck together, so as to ensure that the molten trash bag opening is completely separated from the remaining trash bag body and to ensure good separation of the plastic bag.

[0088] Specifically, the second pusher ramp 92 includes two pusher arms 94 and a connector 95. The two pusher arms 94 are arranged symmetrically at the top and bottom, and the connector 95 is located between the two pusher arms 94. The pusher arms 94 have a second inclined surface 93.

[0089] Furthermore, the pusher arm 94 includes a pusher part 941, a fixing part 942, and a clamping part 943. The pusher part 941 is connected to the fixing part 942. The fixing part 942 is horizontally arranged, and the pusher part 941 is inclined relative to the fixing part 942. The fixing part 942 has a fixing hole 944.

The clamping part 943 is located in the middle of the pusher part 941, and the clamping parts 943 are located on both sides of the pusher part 941. The two back wheels 81 are located in the two clamping parts 943 respectively.

[0090] The second pusher ramp 92 also includes a guard 96, which is located on one side of the pusher arm 94. 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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. The controller 16 is also used to receive the signal transmitted by the sensor 14 to issue an alarm.
