DETAILED DESCRIPTION

[0020] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings, but is not limited thereto. Example 1

[0021] like Figure 1-7 As shown, this embodiment provides a trash can with a dry-wet separation function, including a box body 1 and a box cover 7, one side of the box cover is hinged to the top of the box body, and the box cover 7 can open or close the box body 1; A filter screen 2 is provided in the box body 1, a collecting box 23 is provided on one side below the filter screen, the opening of the collecting box is flush with the filter screen, a bag box 19 is provided on one side above the filter screen 2, and the bag box is fixedly connected to the inner wall of the box body; The left and right walls of the box body 1 are provided with a convex plate 4 and a rack 15. A fixed pin 22 and a movable pin 21 are provided on one side of the convex plate 4. The movable pin 21 is driven to move left and right toward the fixed pin 22 by the lifting and lowering of the convex plate 4. A coil spring 28, a first rope wheel 5, a guide groove 13, a second rope wheel 16 and a pull rope 8 are arranged on the inner rear wall of the box body 1. The coil spring 28 is axially connected to the first rope wheel 5. The second rope wheel 16 is connected to the gear 17 through a long axis. The gear 17 can be meshed with the rack 15, and the rotation of the gear is driven by the lifting of the rack. A slide seat 9 is arranged on the guide groove 13. The slide seat 9 is connected to the fixed clamping hand 12. The movable clamping hand 26 is elastically connected to the fixed clamping hand 12. After the pull rope 8 passes through the connecting slide seat 9, its two ends are respectively connected to the first rope wheel 5 and the second rope wheel 16. The slide seat 9 is driven to move by the pull rope 8 to realize the opening and closing of the movable clamping hand 26 and the fixed clamping hand 12, thereby clamping the garbage bag.

[0022] Specifically, the box body 1 is a closed rectangular parallelepiped, and the box cover 7 is hinged to one side of the top of the box body 1 through a hinge, which is used to close or open the box body 1. There is a filter screen 2 inside the box body 1, which divides the inner part of the box body into two parts, an opening on the side of the filter screen, and a sunken collection box 23 is provided. A bag box 19 is provided above the filter screen close to the side wall of the box body.

[0023] The bottom of the convex plate 4 and the rack 15 are connected to the spring, and the upper surface of the filter screen 2 is provided with a support rod with a spring sleeve, and the bottom of the convex plate 4 and the rack 15 are provided with a long hole, and the spring and the support rod can be placed in the long hole. When the box cover is closed, the box cover 7 presses down the convex plate 4 and the rack 15, and the convex plate and the rack descend and compress the spring to store force.

[0024] A trapezoidal projection is provided on one side of the bottom of the convex plate 4, and the trapezoidal projection contacts one end of the movable needle 21. When the box cover 7 is opened, under the elastic force of the spring, the trapezoidal projection contacts one end of the movable needle during the process of the convex plate 4 rising, and the movable needle is gradually pushed to move by the hypotenuse of the trapezoidal projection, so that the movable needle 21 is away from the fixed needle 22. When the box cover 7 is closed, the box cover 7 presses down the convex plate 4, and when the convex plate 4 descends, the hypotenuse of the trapezoidal projection is used to gradually move the movable needle 21, so that the movable needle 21 is close to the fixed needle 22, and the bag is broken.

[0025] A coil spring 28 is arranged on the rear wall of the box body, and the coil spring 28 is coaxially connected to the first rope wheel 5, and the first rope wheel 5 is coaxially connected to a ratchet 6. A movable seat 3 is also arranged in the box body, and a spring is arranged at the bottom end of the movable seat 3. A push rod is arranged on one side of the movable seat 3, and an elastic pawl 25 is arranged in the push rod. The elastic pawl 25 is connected to the bottom end of the ratchet 6, and the connection with the ratchet 6 can be achieved through the elastic pawl 25; two fixed needles 22 are arranged on the movable seat 3, and one end of the movable needle 21 penetrates the movable seat 3 and contacts with the trapezoidal protrusion, and the needle tip of the movable needle 21 is arranged opposite to the needle tips of the two fixed needles 22. When the movable needle 21 is close to the fixed needle 22, the garbage bag can be squeezed to complete the bag breaking.

[0026] The gear 17 is connected to the long shaft through the one-way bearing 18. The rise of the rack 15 only drives the gear 17 to rotate idly. Only when the rack 15 descends, the rack 15 drives the gear 17, the one-way bearing 18, and the second rope wheel 16 to rotate simultaneously. The second rope wheel 16 drives the slide 9 to move while winding the pull rope 8. In addition, after the rack is opened and the box cover is raised to the right position, there is a toothless section at the bottom of the rack 15. When the box cover 7 is closed and the rack 15 is pressed down, the toothless section cannot drive the gear to rotate during the descent of the rack 15. Only when the box cover is pressed down for a certain distance, the teeth at the bottom of the rack 15 mesh with the gear 17, driving the gear 17 to rotate. The effect of such a design is that when the box cover 7 is opened and a garbage bag is put in, the garbage bag presses down the movable seat 3 due to its own weight, and the movable seat 3 descends to drive the elastic pawl 25 to disengage from the ratchet wheel 6, so that the restraining force of the coil spring 28 disappears, thereby rotating the first rope wheel 5 and pulling the pull rope 8. At this time, the gear 17 has not yet engaged with the rack 15, and does not affect the rope release of the second rope wheel 16. A guide rod 11 is provided on the upper surface of the guide groove 13, and the slide seat 9 can move along the guide rod 11 to ensure that the slide seat 9 moves smoothly and stably.

[0027] The guide groove 13 includes a smooth portion 1301, a wave portion 1304, a corner portion 1302 and a retention portion 1303. The wave portion 1304 connects the smooth portion 1301 and the retention portion 1303 on both sides. The corner portion 1302 is located at one side behind the wave portion 1304 and connects the smooth portion 1301 and the retention portion 1303 on both sides. The width of the wave portion 1304 is only half of the width of the smooth portion 1301, and the length of the wave portion 1304 is also shorter than the length of the smooth portion 1301.

[0028] like Figure 6 As shown, the movable gripper 26 is arranged in the fixed gripper 12 and is sleeved with a spring. The movable gripper 26 can be extended and retracted back and forth in the fixed gripper 12. Both ends of the movable gripper 26 extend out of the fixed gripper 12, one end is a rectangular parallelepiped and the other end is a cone. The cone is placed in the guide groove 13 and can move in the smooth part 1301 and the wave part 1303, and can move the cone from the smooth part 1301 to the retention part 1303 with the help of the corner part 1302; the fixed gripper 12 is fixedly connected to the slide 9, and an elastic latch 10 is also arranged on the fixed gripper 12, and a latch hole 27 is correspondingly arranged on the movable gripper 26. When the elastic latch 10 is placed in the latch hole 27, the movable gripper 26 can be locked. One end of the fixed gripper 12 is also arranged as a rectangular parallelepiped, corresponding to the rectangular parallelepiped of the movable gripper 26, and the two rectangular parallelepipeds can be used to clamp the bag mouth of the garbage bag.

[0029] A bag box 19 is provided below the second rope pulley 16. When the slide seat 9 moves to the end of the guide groove 13, the magnet 14 at the end of the guide groove 13 sucks the elastic latch 10 out of the latch hole 27, and the movable clamp 26 is ejected. The cone enters the smooth portion 1301 of the guide groove and is located at the side and rear of the wavy portion 1303. The rectangular parallelepiped of the movable clamp 26 is separated from the rectangular parallelepiped of the fixed clamp 12, releasing the clamped bag mouth, allowing the empty garbage bag to fall into the bag box 19 and be collected by the bag box 19. Example 2

[0030] A garbage bin with dry and wet separation function, the structure is as described in Example 1, the difference being that: a scraper 20 is further provided on one side of the inner rear wall of the bin 1, the scraper 20 is located above the filter 2, the scraper 20 is connected to a handle, and the handle extends out of the bin 1. When the garbage is dried on the filter 2, the scraper 20 is pulled by pulling the handle on the outside of the bin to push the garbage into the collection box 23. Example 3

[0031] A working method of a garbage bin with dry-wet separation function, using the technical solution described in Example 2, specifically comprises the following steps: 1) Open the box cover 7, the convex plate 4 and the rack 15 rise upward under the action of the spring, and when the rack 15 rises upward, the one-way bearing makes the gear 17 idle, and finally the rack 15 passes over the gear 17, and when the convex plate 4 rises upward, the trapezoidal protrusion forces the movable needle 21 to move away from the fixed needle 22; 2) Put the garbage bag in, and the garbage bag falls on the movable seat 3, causing the movable seat 3 to descend, driving the elastic pawl 25 to disengage from the ratchet 6, so that the restraining force of the coil spring 28 disappears. During the release of the coil spring 28, the coaxial first rope wheel 5 is driven to rotate, and then the first rope wheel 5 rotates to pull the pull rope 8, and the second rope wheel 16 releases the rope at the same time. At this time, the toothless section of the rack 15 descends, and the rack 15 has not yet engaged with the gear 17. While the pull rope 8 is pulled, the slide 9 is driven to move toward the first rope wheel 5. The cone moves in the guide groove 13 and uses the action of the corner portion 1302 to move the movable clamping hand 26 toward the fixed clamping hand 12 to clamp the bag mouth of the garbage bag. At the same time, the elastic latch 10 enters the clamping hole 27, and the movable clamping hand 26 is locked; 3) Close the box cover 7, the convex plate 4 and the rack 15 fall downward, and when the convex plate 4 falls, the movable needle 21 moves toward the fixed needle 22 to pierce the garbage bag; when the rack 15 falls to mesh with the gear 17, the gear 17 rotates and drives the second rope wheel 16 to rotate, and the second rope wheel 16 winds the pull rope 8, so that the slide 9 moves from the retention part 1303 to the second rope wheel 16, and the cone of the movable gripper 26 passes through the wave part 1304 area of ​​the guide groove 13, forming a shake, so that the garbage in the garbage bag falls evenly onto the filter 2; At the same time, the first rope wheel 5 releases the pull rope 8, driving the ratchet wheel 6 to rotate, and re-accumulating force on the coil spring 28; 4) When the slide 9 moves to the end of the guide groove, the magnet 14 at the end of the guide groove sucks the elastic latch 10 out of the latch hole 27, so that the cone of the movable gripper 26 re-enters the smooth portion 1301 of the guide groove 13 and is located at the side and rear of the wave portion 1304. Then the movable gripper 26 is released, so that the garbage bag falls into the bag box 19. At this time, the box cover 7 completely closes the box body 1; 5) After standing for a period of time, the water in the garbage will enter the box below the filter through the filter 2, and then the scraper 20 is pulled, and the scraper 20 pushes the garbage on the filter to fall into the collection box 23.

[0032] Since the entire garbage bin adopts a closed design, the bin has multiple functions such as puncturing, filtering, and collecting. After the garbage bag containing wet garbage is placed in the bin and the lid is closed, multiple functions can be performed. The entire operation process is carried out in a closed bin environment, which does not produce odor, does not attract flies and mosquitoes, and is clean and hygienic.

[0033] The above description is only a specific implementation mode of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
