When the bag pulling slide 15 slides past the clamp opening trigger mechanism 3, the two clamp opening blocks 31 are respectively triggered and cooperated with the corresponding bag pulling clamps 16, so that the clamping head of the bag pulling clamp 16 opens to clamp the garbage bag of the bag hanging mechanism 14. The present invention provides a trash can with a trash bag opening device, which can complete the rapid opening and laying of the trash bag through the coordinated cooperation of the bag pulling mechanism, the clamp opening trigger mechanism and the bag hanging mechanism. It is easy to use, saves time and effort, and further improves the usability and convenience of the trash can device; the trash bag is clamped and laid by the bag pulling clamp, which is stable and reliable, and the trash bag is prevented from being separated from the trash can body under the weight during the process of discarding the trash, and the stability of the trash can device is further improved; the bag pulling mechanism is driven by a manual bag pulling drive mechanism, so that the trash bag can be quickly installed, and the use of electrical components such as motors is eliminated, thereby further reducing the preparation cost of the trash can device and facilitating its promotion.

[0034] Specifically, the bag pulling clamp 16 includes an A-type clamp; an assembly groove is respectively provided on both sides of the bag pulling slide 15, in which a clamp opening handle 2 and an A-type clamp are rotatably installed respectively, and a torsion spring is connected between the clamp opening handle 2 and the bag pulling slide 15, and the clamp head of the A-type clamp protrudes from the front side of the bag pulling slide 15; wherein, the clamp opening handle 2 includes a transmission rotating arm 221 and a clamp opening rotating arm 222 which are staggered along the axial direction of its rotation axis; the end of the transmission rotating arm 221 protrudes from the top surface of the bag pulling slide 15 and is movably abutted against the clamp opening block 31; the clamp opening rotating arm 222 intersects with the A-type clamp along the vertical projection, and when the transmission rotating arm 221 moves toward the bag hanging mechanism 14 to abut the clamp opening block 31, the transmission rotating arm 221 is blocked and rotates around its rotation axis, and the clamp opening rotating arm 222 slides against the clamp body of the A-type clamp to open the clamp head of the A-type clamp.

[0035] Specifically, an arm angle 228 is formed between the transmission arm 221 and the clamping opening arm 222 , and the length of the transmission arm 221 is greater than the length of the clamping opening arm 222 .

[0036] Specifically, the trigger reset member adopts a cylindrical coil spring 355, and a first spring fixing column 352 extends upward from the top surface of the trigger slide 351, and a second spring fixing column 342 extends downward from the corresponding slider fixing seat 34, and the first spring fixing column 352 is coaxial with the second spring fixing column 342, and the upper and lower ends of the cylindrical coil spring 355 are respectively tightly sleeved on the first spring fixing column 352 and the second spring fixing column 342 to achieve the downward sliding reset of the trigger slide 351.

[0037] Specifically, the lower handle 22 includes a transmission arm 221, an opening arm 222 and an arm reset torsion spring 223. The lower end of the transmission arm 221 and the lower end of the opening arm 222 are fixedly connected or integrally formed with a shaft portion 224. The shaft portion 224 is rotatably connected to the bag pulling slide 15. There is a shaft angle 228 between the transmission arm 221 and the opening arm 222. The angle of the shaft angle 228 is 15°~135°. The arm reset torsion spring 223 is installed between the opening arm 222 and the bag pulling slide 15. Preferably, the arm angle 228 is between 45° and 90°. If the arm angle 228 is too small, the rotation angle of the opening arm 222 will be insufficient, and the bag clamp 16 cannot be fully opened. If the arm angle 228 is too large, the rotation angle of the opening arm 222 will be excessive, causing the opening arm 222 to interfere with the bag clamp 16, thereby being unable to continue to drive the bag pull slide 15 to move toward the bag hanging mechanism 14.

[0038] Specifically, a limiting groove 225 is provided on the front side of the transmission rotating arm 221, the middle part of the upper rotating handle 21 is rotatably connected to the upper end of the transmission rotating arm 221, the lower end of the upper rotating handle 21 is abutted against the limiting groove 225, and the limiting groove 225 extends to the side to form a reset top block 226, and the elastic member 25 is connected between the reset top block 226 and the upper rotating handle 21 to realize the rotation and reset of the upper rotating handle 21 and abut against the limiting groove 225; the rotating shaft part 224 extends to the side to form a limiting part 227, and the limiting part 227 is limitedly matched with the bag pulling slide 15 A rotating hole 23 is opened in the middle of the rotating shaft part 224, and a rotating rod 24 is inserted into the rotating hole 23. The rotating rod 24 is movably connected to the rotating hole 23. The length of the rotating rod 24 is greater than the depth of the rotating hole 23. The left and right ends of the rotating rod 24 are movably connected to the bag pulling slide 15. The middle part of the rotating arm reset torsion spring 223 is sleeved on either end of the rotating rod 24. The first end of the rotating arm reset torsion spring 223 abuts against the bag pulling slide 15, and the second end of the rotating arm reset torsion spring 223 abuts against the clamping rotating arm 222 to realize the rotation and reset of the lower rotating handle 22.

[0039] Through the limit groove 225 and the elastic member 25, the lower end of the upper handle 21 is abutted against the limit groove 225, at which time the upper handle 21 and the transmission arm 221 are kept in the same straight line, and the rear side of the upper handle 21 abuts against the front side of the trigger part 311 to drive the transmission arm 221 to rotate downward with the shaft part 224 as the axis, thereby driving the clamping arm 222 to rotate upward, and the bag clamp 16 is opened by the clamping arm 222, which has a simple structure and high reliability. After the bag clamp 16 clamps the garbage bag, the bag pull slide 15 is separated from the bag hanging mechanism 14, and the front side of the upper handle 21 contacts and abuts against the triggering abutting inclined surface 312 of the trigger part 311 again, the upper handle 21 rotates downward, and at the same time, under the guidance of the triggering abutting inclined surface 312, the triggering slider moves upward, so that the bag pull slide 15 passes through the clamping trigger mechanism to prevent interference with it.

[0040] Specifically, an upper pulley 213 is installed at the end of the transmission rotating arm 221 .

[0041] Specifically, the movable block structure includes two clamping blocks 31 movably arranged at the bottom of the barrel cover 12 in the horizontal or vertical direction. A compression spring is respectively connected between the two clamping blocks 31 and the barrel cover 12. The sides of the two clamping blocks 31 are formed with avoidance matching inclined surfaces. At least during the backward resetting process of the bag pulling mechanism, the end of the transmission rotating arm 221 slides and abuts against the avoidance matching inclined surface to achieve the avoidance matching of the clamping blocks 31 in the horizontal or vertical direction.

[0042] Specifically, the movable block structure includes two guide slide bars 341 symmetrically arranged at the bottom of the barrel cover 12 , and the clamping block 31 is provided with a slide hole 354 cooperating with the guide slide bar 341 , and the clamping block 31 is installed on the guide slide bar 341 by sliding up and down through the slide hole 354 .

[0043] Specifically, parallel slide fixing columns 18 are respectively arranged on both sides of the discarding port 13, and both sides of the bag pulling slide 15 are respectively slidably connected to the corresponding slide fixing columns 18; the elastic connecting part includes a slide reset spring, one end of the slide reset spring is connected to the barrel cover 12, and the other end is connected to the bag pulling slide 15; the bag pulling drive mechanism includes a handle and a pull rope, one end of the pull rope is connected to the bag pulling slide 15, and the other end is connected to the handle; the pull rope and the slide reset spring have opposite traction directions.

[0044] This embodiment provides a clamping trigger mechanism 3 with an upper and lower avoidance structure, which abuts against the clamping stopper 31 when the bag pulling mechanism retreats, causing it to retreat up and down, thereby preventing the bag pulling mechanism from being stuck when retreating, and is stable and reliable.

[0045] like Figure 5 As shown, the clamping block 31 can also be set as a fixed block structure, which includes two clamping blocks 31 fixedly set at the bottom of the barrel cover 12. The front sides of the two clamping blocks 31 are respectively formed with triggering abutting inclined surfaces 312 tilted backward. During the process of the bag pulling mechanism retreating and resetting, the end of the transmission arm 221 slides and abuts against the triggering abutting inclined surfaces 312 to drive the transmission arm 221 to rotate downward to avoid. This fixed block structure uses the directional idle travel of the clamping handle 2 to avoid the clamping block 31, so as to avoid the bag pulling mechanism from retreating and getting stuck. The structure is simpler and the cost is lower.

[0046] like Figure 6 As shown, this embodiment also provides a hinged arm structure, which includes an upper turn handle 21 and a lower turn handle 22 that are hinged to each other, and an elastic member 25 for resetting the upper turn handle 21 is connected between the upper turn handle 21 and the lower turn handle 22. A limiting structure is formed at the hinge of the upper turn handle 21 and the lower turn handle 22, and the limiting structure includes a limiting groove 225 and a limiting support arm that are relatively formed on the upper turn handle 21 or the lower turn handle 22. The limiting groove 225 and the limiting support arm are limited and abutted to each other to achieve the connection of the upper turn handle 21 and the lower turn handle 22 to form a straight arm body.

[0047] Specifically, the clamp opening handle 2 includes an upper handle 21 and a lower handle 22 that are rotatably matched, and an elastic member 25 for resetting the upper handle 21 is connected between the upper handle 21 and the lower handle 22; the lower handle 22 is movably connected to the bag pulling clamp 16; an opening trigger mechanism 3 is also installed at the bottom of the bucket cover 12 or the top of the trash can body 1, and the opening trigger mechanism 3 includes a trigger part 311 that slides left and right. When clamping the bag, the trigger part 311 movably cooperates with the upper handle 21 to open the bag pulling clamp 16 and clamp the garbage bag. The bag pulling mechanism moves back and forth, so that the bag pulling clamp 16 clamps the bag on the bag hanging mechanism 14 and pulls it out therefrom. No special bag-passing consumables are required, and the consumables cost is low. The bag pulling clamp 16 has a large clamping force and high reliability. In the process of the bag pulling mechanism sliding back and forth, the clamp opening handle 2 touches the clamp opening block 31, so that the clamp opening handle 2 rotates to drive the bag pulling clamp 16 to open and clamp the bag. The structure is simple and the cost is low. When the clamp opening handle 2 abuts against the clamp opening block 31, the clamp opening block 31 moves laterally toward the center, reducing the driving force of the bag pulling mechanism to move back and forth, making it more labor-saving to pull the bag pulling mechanism, reducing the driving cost, and making it more convenient to use.

[0048] Specifically, the lower end of the transmission arm 221 and the lower end of the clamping arm 222 are fixedly connected or integrally formed with a shaft portion 224, and the shaft portion 224 is rotatably connected to the bag pulling slide 15. There is a shaft angle 228 between the transmission arm 221 and the clamping arm 222, and the angle of the shaft angle 228 is 15°~135°. The arm reset torsion spring 223 is installed between the clamping arm 222 and the bag pulling slide 15, the clamping arm 222 and the bag pulling clamp 16 are movably abutted against each other, and the upper handle 21 is rotatably installed on the transmission arm 221.

[0049] Specifically, a limiting groove 225 is opened on the front side of the transmission rotating arm 221, the middle part of the upper rotating handle 21 is rotationally connected with the upper end part of the transmission rotating arm 221, the lower end part of the upper rotating handle 21 is abutted against the limiting groove 225, and a reset top block 226 is extended to the side of the limiting groove 225. The elastic member 25 is connected between the reset top block 226 and the upper rotating handle 21 to realize the rotation reset of the upper rotating handle 21 and abut against the limiting groove 225.

[0050] Through the limiting groove 225 and the elastic member 25, the lower end of the upper turning handle 21 is pressed against the limiting groove 225, and at this time, the upper turning handle 21 and the transmission turning arm 221 are kept in the same straight line, and the rear side of the upper turning handle 21 presses against the clamping stopper 31 to drive the transmission turning arm 221 to rotate downward with the rotating shaft 224 as the axis, thereby driving the clamping turning arm 222 to rotate upward, and the bag pulling clamp 16 is opened by the clamping turning arm 222, which has a simple structure and high reliability. After the bag pulling clamp 16 clamps the garbage bag, the bag pulling slide 15 is separated from the bag hanging mechanism 14, and when the front side of the upper turning handle 21 contacts and presses against the clamping stopper 31 again, the upper turning handle 21 rotates downward, compressing the elastic member 25, so that the bag pulling slide 15 passes through the clamping stopper 31 to prevent interference with it.

[0051] Specifically, a limiting portion 227 extends to the side of the rotating shaft portion 224, and the limiting portion 227 is limitedly matched with the bag pulling slide 15. A rotating hole 23 is opened in the middle of the rotating shaft portion 224, and a rotating rod 24 is inserted into the rotating hole 23. The rotating rod 24 is movably connected to the rotating hole 23, and the left and right ends of the rotating rod 24 are movably connected to the bag pulling slide 15. The middle part of the rotating arm reset torsion spring 223 is sleeved on either end of the rotating rod 24, and the first end of the rotating arm reset torsion spring 223 abuts against the bag pulling slide 15, and the second end of the rotating arm reset torsion spring 223 abuts against the clamping rotating arm 222 to realize the rotation and reset of the switch rotating handle; when the lower rotating handle 22 is rotated to open the clamp, in order to prevent the lower rotating handle 22 from rotating excessively and causing the lower rotating handle 22 to separate from the bag pulling clamp 16, when the bag pulling clamp 16 is opened to the maximum, the limiting portion 227 abuts against the bag pulling slide 15 to prevent the lower rotating handle 22 from rotating excessively.

[0052] The length of the rotating rod 24 is greater than the depth of the rotating hole 23, the clamping handle 2 and the rotating rod 24 slide and cooperate with each other, the inner side of the switch handle abuts and cooperates with the bag pulling slide 15, and the outer side of the switch handle abuts against the arm reset torsion spring 223, so as to realize the sliding reset of the switch handle. The clamping handle 2 is kept at a better matching angle relative to the clamping block 31 by the handle reset spring 223 to avoid the phenomenon of jamming and the like; when the clamping handle 2 abuts against the clamping block 31, not only the clamping block 31 moves laterally toward the center of the trash can, but also the clamping handle 2 moves laterally toward the outside of the trash can and squeezes the arm reset spring 223, further reducing the driving force of the bag pulling mechanism to move forward and backward, making it more labor-saving to pull the bag pulling mechanism, reducing the driving cost, and making it more convenient to use and less prone to jamming; when the clamping handle 2 is separated from the clamping block 31, the arm reset spring 223 simultaneously resets the clamping handle 2 for sliding and rotating.

[0053] Of course, if Figure 7 As shown, the clamp opening handle 2 can also be set as an integrally formed handle monomer, the integrally formed clamp opening handle 2, the clamp opening handle 2 is rotatably installed on the bag pulling slide 15, and an elastic member for rotational reset is connected between the clamp opening handle 2 and the bag pulling slide 15; a clamp opening trigger mechanism is provided on the side of the discarding port 13 close to the bag hanging mechanism 14, and the clamp opening trigger mechanism includes at least one trigger part 311 that can be elastically reset up and down, and each trigger part 311 is respectively on the movement trajectory of the corresponding clamp opening handle 2, and the trigger part 311 and the clamp opening handle 2 are movably abutted to cooperate with each other to drive the corresponding bag pulling clamp 16 to open the mouth and clamp the bag.

The one-piece opening handle 2 drives the clamp to open and clamp the bag, which has high structural strength and low failure rate, thereby improving the stability of the bag clamping assembly and the entire trash can.

[0055] The specific operation is as follows: under the drive of the bag pulling drive mechanism, the bag pulling slide 15 moves from the clamping position toward the bag hanging mechanism 14 to prepare for clamping the bag; the bag pulling slide 15 continues to move forward to the clamping position, the clamping arm 222 of the clamping handle 2 abuts against the trigger part 311, the clamping handle 2 rotates counterclockwise, and the clamping arm 222 of the clamping handle 2 slides against the lower clamping body of the bag pulling clamp 16 to drive the top bag pulling clamp 16 to open and cooperate; the bag pulling slide 15 continues to move forward to the bag clamping position, the transmission arm 221 of the clamp opening handle 2 is separated from the trigger part 311, and under the elastic torque of the arm reset torsion spring 223, the clamp opening handle 2 rotates clockwise, and the bag clamp 16 closes and clamps the bag; the bag pulling slide 15 retreats and resets through the trigger part 311, and the trigger abutment slope 312 on the front side of the trigger part 311 slides and abuts with the clamp opening arm 222 of the clamp opening handle 2 to drive the trigger slider to avoid upward.

Under normal conditions, two bag clamps 16 and the two bag hanging columns 142 support and fix the inner and outer sides of the garbage bag respectively, and form a four-point garbage bag laying structure. The special design of the bag storage box and the garbage bag can realize the rapid laying of the bottom-sealed garbage bag.

The two abutting inclined surfaces are slidably butted against each other, thereby driving the clamp opening handle 2 to move horizontally, so that the clamp opening arm 222 is connected with the A-type clamp.

[0063] Specifically, a guiding slope 212 is also formed on the upper part of the transmission arm 221. When the transmission arm 221 is separated from the clamping block 31, the guiding slope 212 of the transmission arm 221 slides and guides with the edge of the clamping block 31 to avoid jamming between the clamping handle 2 and the clamping block 31, thereby further improving the opening and closing stability of the bag clamping assembly.

The trigger portion 311 includes a trigger abutting inclined surface 312 inclined from top to bottom, and the abutting top includes a rear abutting inclined surface 211 inclined from bottom to top.

[0068] Specifically, a guiding slope 212 is also formed on the upper part of the transmission arm 221. When the transmission arm 221 is separated from the clamping block 31, the guiding slope 212 of the transmission arm 221 slides and guides with the edge of the clamping block 31 to avoid jamming between the clamping handle 2 and the clamping block 31, thereby further improving the opening and closing stability of the bag clamping assembly.

[0069] Specifically, the clamping stopper 31 is provided with a stopper slide groove 313 , and the stopper slide groove 313 is extended in the left-right direction.
