Description

Technical Field

[0001] This invention relates to the field of children's waste sorting bins, specifically a children's waste sorting bin. Background Technology

[0002] The children's waste sorting bin is a trash can designed specifically for children aged 6-12, mainly to help children develop good habits of waste sorting and resource recycling from an early age.

[0003] When using existing children's trash cans, there is an air gap between the trash bag and the can wall after it is put inside. This prevents the trash bag from fitting tightly against the inner wall of the can, reducing the effective capacity of the trash bag. When the trash bag is full, the opening of the bag needs to be tightened manually before it can be taken out. This makes it easy for operators to come into direct contact with the trash, affecting the user experience and hygiene of the children's trash can.

[0004] To address the aforementioned issues, we propose a children's waste sorting bin. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a children's waste sorting bin. When the storage compartment block is pushed or pulled, the moving wheel drives the crank rod to rotate, which in turn drives the piston block to reciprocate and generate continuous negative pressure. This pressure is applied to the surface of the garbage bag through the suction port, causing the garbage bag to fit tightly against the inner wall of the storage bin, eliminating air gaps between the bag walls, and effectively expanding the garbage bag's capacity. Furthermore, when the garbage bag is full and blocks the suction port, negative pressure accumulates in the ring cavity and overcomes the damping spring force to pull the movable block, triggering the normally open start switch to start the electric ring guide rail to rotate, which drives the elastic band to wrap around and tighten the garbage bag opening. The sealing can be completed without manual contact with the garbage, avoiding direct contact between the operator and the garbage, improving hygiene and user experience.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a children's waste sorting bin, comprising a bin body, a support guide rail fixedly installed at the bottom of the bin body, push arc blocks embedded in the left and right sides of the surface of the bin body, and storage slot blocks fixedly installed on the side of the two push arc blocks near the bin body, a partition plate fixedly installed at the center of the lower side of the inner wall of the two storage slot blocks, and a suction cavity opened on the lower side inside the two storage slot blocks; Two storage bins are provided on the inner wall of each of the two storage bins. A ring cavity is provided on the lower side of the interior of each of the four storage bins. Several suction ports are provided on the upper periphery of the inner wall of each of the four ring cavities. A blocking valve is provided on the inner wall of each suction port. A locking assembly is provided on the side of the inner wall of each of the four ring cavities near the partition plate. Two conical suction pipes are fixedly installed on the upper part of the inner wall of the two suction chambers, located below the two storage garbage bins. A conical connection port is opened on the upper side of each conical suction pipe on the inner wall of the annular cavity. The conical connection port is connected to the conical suction pipe to transmit the negative pressure generated in the suction chamber to the annular cavity. A power component is provided at the bottom of the two storage tanks.

[0007] Furthermore, the front and rear sides of the two storage slots are slidably connected to the inner wall of the box via slide rails, and the two pushing arc blocks are attached to the outer periphery of the box.

[0008] Furthermore, a controller is provided on the top of the box, and a protective cover is rotatably installed on the rear side of the top of the box around the controller, with the protective cover fitting snugly against the surface of the box. Four radar sensors are located on the upper front of the box. Each radar sensor has a sensor cover on the lower side of the front of the box. The radar sensors and sensor covers work together to detect a child's throwing motion. The door can be opened automatically when the child throws the object, ensuring safety and convenience. The protective cover, together with two pushing arc blocks, forms a complete arc surface on the outer periphery of the box. The support rails of the device ensure the overall stability of the device. The pushing arc blocks of the device are connected to the box using a locking mechanism.

[0009] Furthermore, the four storage trash cans are respectively positioned directly below the corresponding sensor covers, and the two storage trash cans located within the storage trough are respectively arranged on opposite sides of the partition plate; an opening is provided at the location of the sensor cover for trash to pass through and fall into the storage trash can.

[0010] Furthermore, the locking assembly includes an activation groove formed on the upper side of the inner wall of the annular cavity, a movable block slidably installed on the inner wall of the activation groove, a damping spring fixedly installed on the top surface of the movable block, a perforated plate fixedly installed on the lowest side of the inner wall of the activation groove, and a normally open activation switch fixedly installed at the center of the top of the perforated plate. An electric circular guide rail is fixedly installed on the upper side of the annular cavity of the inner wall of the storage garbage bin, and an elastic band is fixedly installed on the moving end of the electric circular guide rail.

[0011] Furthermore, the telescopic end of the damping spring is fixedly connected to the upper side of the inner wall of the starting groove, and one end of the elastic band is fixedly connected to the inner wall of the storage trash can. When the storage block is pulled out of the container, the garbage bag contains garbage. The garbage bag fits against the suction port, and the suction force causes negative pressure to accumulate in the annular cavity. The negative pressure drives the movable block to move and fit against the normally open start switch, triggering the electric annular guide rail to rotate one revolution. The electric annular guide rail of this device is controlled by the controller to rotate only one revolution. The controller of this device is existing technology, and this device will not be described in detail. During the rotation of the electric annular guide rail, because one end of the elastic band is fixed to the inner wall of the storage garbage bin, the elastic band causes the garbage bag opening to contract under the traction of the electric annular guide rail, so as to facilitate the bag removal operation.

[0012] Furthermore, each of the conical suction pipes is a conical structure with a smaller upper end and a larger lower end, and a sealing ring is fixedly installed on the pipe wall of each conical suction pipe. The sealing ring is used to seal when the conical suction pipe is connected to the storage garbage can.

[0013] Furthermore, an activated carbon plate is embedded in the inner wall of the suction chamber directly below the two conical suction pipes. The lower end of the activated carbon plate extends through to the bottom of the storage tank block, and the bottom of the activated carbon plate is fixedly connected to the top of the storage tank block by bolts.

[0014] Furthermore, the power assembly includes two movable wheels fixedly installed at the bottom of the storage tank block, a crank rod fixedly installed between the axles of the two movable wheels, a connecting rod rotatably installed at each of the two crank positions of the crank rod, and a piston block fixedly installed at the upper end of each of the two connecting rods; The two piston blocks are slidably installed in their respective piston cylinders. The bottom of the storage tank block is located inside the two piston cylinders and a first air pipe is fixedly installed in each of them. A second air pipe is fixedly installed on the upper part of the surface of the two piston cylinders away from the first air pipe. Check valves are fixedly installed on the inner walls of the two first air pipes and the two second air pipes.

[0015] Furthermore, the two cranks of the crank rod are arranged in an alternating vertical arrangement. When the crank rod rotates, at least one piston cylinder is in operation. The tops of both piston cylinders are fixedly connected to the bottom surface of the storage tank block. The check valve in the first air pipe restricts the gas flow to the piston cylinder only from the suction chamber, and the check valve in the second air pipe restricts the gas flow to the piston cylinder only from the piston cylinder outward. The top of the first air pipe extends through to the inner wall of the suction chamber, providing negative pressure power to the suction chamber.

[0016] Compared with the prior art, the present invention provides a child-friendly waste sorting bin, which has the following beneficial effects: 1. The device uses a moving wheel to rotate a crank rod when the storage trough block is pushed or pulled, which drives the piston block to reciprocate and generate continuous negative pressure. This pressure is applied to the surface of the garbage bag through the suction port, making the garbage bag fit tightly against the inner wall of the storage garbage bin, eliminating air gaps between the bag walls and effectively expanding the garbage bag's capacity. Furthermore, when the garbage bag is full and blocks the suction port, negative pressure accumulates in the ring cavity and overcomes the damping spring force to pull the movable block, triggering the normally open start switch to start the electric ring guide rail to rotate, which drives the elastic band to wrap around and tighten the garbage bag opening. The sealing can be completed without manual contact with the garbage, avoiding direct contact between the operator and the garbage, improving hygiene and user experience.

[0017] 2. This device uses the moving wheels to directly convert the mechanical energy of pushing and pulling the storage tank into negative pressure power, eliminating the need for an electric air pump and external power source, reducing energy consumption and not being limited by battery life, making it suitable for use by children.

[0018] 3. The device uses a radar sensor to detect a child's throwing motion and controls the sensor-activated round cover to open automatically, eliminating the need for the child to manually open the cover and making it easy to operate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 11 In this embodiment, a children's waste sorting bin includes a bin body 1. A support rail 2 is fixedly installed at the bottom of the bin body 1. Pushing arc blocks 3 are embedded in the left and right sides of the surface of the bin body 1. Storage slot blocks 4 are fixedly installed on the side of the two pushing arc blocks 3 close to the bin body 1. The front and rear sides of the two storage slot blocks 4 are slidably connected to the inner wall of the bin body 1 through slide rails 401. The two pushing arc blocks 3 are attached to the outer periphery of the bin body 1. A partition plate 5 is fixedly installed at the center of the lower side of the inner wall of the two storage slot blocks 4. A suction cavity 6 is opened on the lower side inside the two storage slot blocks 4. A controller 101 is provided on the top of the housing 1. A protective cover 102 is rotatably installed on the rear side of the top of the housing 1 around the controller 101. The protective cover 102 is in contact with the surface of the housing 1. Four radar sensors 103 are located on the upper front of the housing 1. Each radar sensor 103 is located below a sensing cover 104 on the front of the housing 1. The radar sensors 103 and sensing covers 104 work together to detect a child's throwing motion and automatically open the door when the child throws the object, ensuring safety and convenience. The protective cover 102, together with two pushing arc blocks 3, forms a complete arc surface on the outer periphery of the housing 1. The support rail 2 of the device ensures the overall stability of the device. The pushing arc blocks 3 of the device are connected to the housing 1 by a locking mechanism.

[0023] Two storage bins 7 are provided on the inner walls of the two storage troughs 4. The four storage bins 7 are respectively located directly below the corresponding sensor cover 104. The two storage bins 7 located in the storage troughs 4 are respectively arranged on opposite sides of the partition plate 5. An opening is provided at the location of the sensor cover 104 for garbage to pass through and fall into the storage bins 7. An annular cavity 8 is provided on the lower side of the interior of the four storage bins 7. Several suction ports 9 are provided on the upper periphery of the inner wall of the four annular cavities 8. A blocking valve 10 is provided on the inner wall of each suction port 9. A locking assembly 11 is provided on the side of the upper inner wall of the four annular cavities 8 near the partition plate 5. The locking assembly 11 includes an activation groove 1101 formed on the upper side of the inner wall of the annular cavity 8. A movable block 1102 is slidably installed on the inner wall of the activation groove 1101. A damping spring 1103 is fixedly installed on the top surface of the movable block 1102. A perforated plate 1104 is fixedly installed on the lowermost side of the inner wall of the activation groove 1101. A normally open start switch 1105 is fixedly installed at the center of the top of the perforated plate 1104. An electric ring-shaped guide rail 1106 is fixedly installed on the upper side of the annular cavity 8 on the inner wall of the storage trash can 7, and an elastic band 1107 is fixedly installed on the moving end of the electric ring-shaped guide rail 1106. The telescopic end of the damping spring 1103 is fixedly connected to the upper side of the inner wall of the starting groove 1101, and one end of the elastic band 1107 is fixedly connected to the inner wall of the storage garbage bin 7. When the storage block 4 is pulled out of the container 1, the garbage bag contains garbage and is in contact with the suction port 9. The suction force causes negative pressure to accumulate in the annular cavity 8. The negative pressure drives the movable block 1102 to move and engage with the normally open start switch 1105, triggering the electric annular guide rail 1106 to rotate one revolution. The electric annular guide rail 1106 of this device is controlled by the controller 101 to rotate only one revolution. The controller 101 of this device is existing technology and will not be described in detail. During the rotation of the electric annular guide rail 1106, because one end of the elastic band 1107 is fixed to the inner wall of the storage garbage bin 7, the elastic band 1107 causes the garbage bag opening to shrink under the traction of the electric annular guide rail 1106, so as to facilitate the bag retrieval operation.

[0024] Each conical suction pipe 12 has a conical structure with a smaller upper end and a larger lower end. Each conical suction pipe 12 has a sealing ring 1201 fixedly installed on its pipe wall. The sealing ring 1201 is used to seal the conical suction pipe 12 when it is connected to the garbage storage bin 7. An activated carbon plate 601 is embedded in the inner wall of the suction chamber 6, directly below the two conical suction pipes 12. The lower end of the activated carbon plate 601 extends through to the bottom of the storage tank 4, and the bottom of the activated carbon plate 601 is fixedly connected to the top of the storage tank 4 by bolts.

[0025] Two conical suction pipes 12 are fixedly installed on the upper part of the inner wall of the two suction chambers 6, located below the two storage garbage bins 7. A conical connection port 13 is provided on the inner wall of the annular cavity 8 above each conical suction pipe 12. The conical connection port 13 is connected to the conical suction pipe 12 to transmit the negative pressure generated in the suction chamber 6 to the annular cavity 8. A power assembly 14 is provided at the bottom of each of the two storage troughs 4.

[0026] The power assembly 14 includes two movable wheels 1401 fixedly installed at the bottom of the storage tank block 4. A crank rod 1402 is fixedly installed between the axles of the two movable wheels 1401. A connecting rod 1403 is rotatably installed at both crank positions of the crank rod 1402. A piston block 1404 is fixedly installed at the upper end of the two connecting rods 1403. Two piston blocks 1404 are slidably installed in the corresponding piston cylinders 1405. The bottom of the storage tank block 4 is located inside the two piston cylinders 1405 and a first air pipe 1406 is fixedly installed in each of them. A second air pipe 1407 is fixedly installed on the upper side of the surface of the two piston cylinders 1405 away from the first air pipe 1406. Check valves 1408 are fixedly installed on the inner walls of the two first air pipes 1406 and the two second air pipes 1407. The two cranks of the crank 1402 are arranged in an alternating vertical arrangement. When the crank 1402 rotates, at least one piston cylinder 1405 is in operation. The tops of both piston cylinders 1405 are fixedly connected to the bottom surface of the storage tank block 4. The check valve 1408 in the first air pipe 1406 restricts the gas to flow only from the suction chamber 6 to the piston cylinder 1405. The check valve 1408 in the second air pipe 1407 restricts the gas to be discharged only from the piston cylinder 1405. The top of the first air pipe 1406 extends through to the inner wall of the suction chamber 6, providing negative pressure power to the suction chamber 6.

[0027] The technical features that distinguish this device from existing technologies are as follows: The bottom of the storage tank 4 is equipped with a movable wheel 1401. The axle of the movable wheel 1401 drives the crank 1402 to rotate. The crank 1402 drives the piston block 1404 to reciprocate in the piston cylinder 1405 through the connecting rod 1403. Through the one-way air guiding action of the check valve 1408 in the first air pipe 1406 and the second air pipe 1407, the gas in the suction chamber 6 is extracted to form a continuous negative pressure, which directly converts the mechanical energy of the pushing and pulling action into negative pressure power without the need for an electric air pump. Several suction ports 9 are opened on the upper periphery of the inner wall of the annular cavity 8. Each suction port 9 has a barrier valve 10 on its inner wall. It opens under negative pressure to allow airflow to pass through, and closes when the negative pressure disappears to prevent backflow. The negative pressure in the suction cavity 6 is transmitted to the annular cavity 8 through the conical suction pipe 12 and the conical connecting port 13, so that the garbage bag adheres to the wall of the bin. A movable block 1102 is slidably installed inside the starting slot 1101. A damping spring 1103 is provided on the top surface of the movable block 1102. A normally open starting switch 1105 is provided at the bottom of the starting slot 1101. When the garbage bag is full, it blocks the suction port 9. Negative pressure accumulates in the annular cavity 8, which overcomes the elastic force of the damping spring 1103 and pulls the movable block 1102 to press against the normally open starting switch 1105, triggering the sealing action. The automatic triggering of sealing is achieved through the accumulation of negative pressure. The inner wall of the storage garbage bin 7 is equipped with an electric ring guide rail 1106, and an elastic band 1107 is fixed at its moving end. One end of the elastic band 1107 is fixed to the bin wall. The electric ring guide rail 1106 is rotated one revolution under control, and the elastic band 1107 moves along the ring track to make the garbage bag opening wrap around and tighten, which can adapt to different bag opening sizes. Four radar sensors 103 are installed on the front of the box 1. Each radar sensor 103 has a sensing cover 104 on its lower side. The radar sensor 103 is used to detect the child's throwing action and control the sensing cover 104 to open automatically, so as to realize orientation detection and automatic door opening. When the storage compartment 4 is pushed or pulled, the moving wheel 1401 rolls and drives the crank 1402 to rotate. The piston block 1404 reciprocates and generates negative pressure, causing the garbage bag to stick to the wall of the bin. When the garbage bag is full, it blocks the suction port 9, causing the negative pressure to accumulate and triggering the normally open start switch 1105. The electric ring rail 1106 rotates and drives the elastic band 1107 to shrink the bag opening. The pushing and pulling action synchronously drives the generation of negative pressure, the sticking of the garbage bag and the sealing trigger, creating a triple linkage without the need for an independent power source.

[0028] The working principle of the above embodiments is as follows: The device automatically opens the door when a child throws the trash, triggering a sensor. The trash falls into the corresponding storage trash can 7 through the opening of the sensor cover 104. At the same time, the device's moving wheel 1401 drives the power component 14 to generate negative pressure as it pushes and pulls the storage compartment 4, causing the trash bag to fit against the suction opening 9 on the inner wall of the trash can. After the trash is full, the negative pressure triggers the locking component 11 to automatically tighten the bag opening, making it easy to remove the trash bag. Specifically, when a child brings the trash close to the corresponding category of sensor cover 104, the radar sensor 103 on the front of the bin 1 detects the throwing action, and the controller 101 controls the sensor cover 104 to open automatically, and the trash falls through the opening into the storage trash can 7 directly below. The four storage trash cans 7 correspond to the four sensor covers 104 respectively, and are separated on both sides of the storage compartment 4 by the partition plate 5, so as to realize the classified collection of trash. During the process of pushing and pulling the storage tank 4 into and out of the box 1, the two moving wheels 1401 at the bottom of the storage tank 4 roll on the ground, and the axle of the moving wheels 1401 drives the crank 1402 to rotate. The two cranks of the crank lever 1402 are arranged in an alternating manner, and through the connecting rod 1403, they drive the two piston blocks 1404 to move alternately and reciprocally in the two piston cylinders 1405. The piston cylinders 1405 are connected to the suction chamber 6 through the first air pipe 1406. The check valve 1408 in the first air pipe 1406 restricts the gas to flow only from the suction chamber 6 to the piston cylinder 1405. The check valve 1408 in the second air pipe 1407 restricts the gas to be discharged only from the piston cylinder 1405. When the piston block 1404 reciprocates, it draws out the gas in the suction chamber 6 and discharges it to the outside, so that a continuous negative pressure is formed in the suction chamber 6. The negative pressure in the suction chamber 6 is transmitted to the annular cavity 8 on the lower side of the storage garbage bin 7 through the conical suction pipe 12 and the conical connection port 13. The conical suction pipe 12 has a conical structure with a small upper end and a large lower end. The sealing ring 1201 on the pipe wall ensures the airtightness of the connection. The negative pressure in the annular cavity 8 is applied to the surface of the garbage bag in the storage garbage bin 7 through the suction port 9 on the upper periphery of the inner wall. Under the action of negative pressure, the garbage bag is pressed tightly against the inner wall of the storage garbage bin 7 and the suction port 9. The barrier valve 10 set on the inner wall of each suction port 9 opens under the action of negative pressure to allow airflow. When the negative pressure disappears, the barrier valve 10 closes to prevent garbage or odor from flowing back. When the garbage bag in the storage garbage bin 7 is full of garbage, the garbage bag adheres to the suction port 9 and blocks the suction port 9. The negative pressure in the annular cavity 8 continues to accumulate. The accumulated negative pressure acts on the movable block 1102 through the starting groove 1101, overcoming the elastic force of the damping spring 1103 and pulling the movable block 1102 downward. The movable block 1102 presses against the normally open start switch 1105 on the perforated plate 1104. When the electric ring guide rail 1106 is triggered to rotate one revolution, the electric ring guide rail 1106 rotates, driving the elastic band 1107, which is fixed to the inner wall of the storage garbage can 7, to move along the ring track. The elastic band 1107 shrinks and ties the garbage bag opening from the outside of the bag opening, completing a simple sealing of the bag opening, making it easy for people to take it out. The suction chamber 6 is also equipped with an activated carbon plate 601 to filter and deodorize the gas entering the suction chamber 6, preventing odor leakage. When the storage block 4 is pulled out of the container 1, the push-pull action synchronously drives the power component 14 to continuously generate negative pressure, providing a power source for the sealing action. At the same time, the negative pressure keeps the garbage bag tightly against the container wall, preventing the bag from collapsing or shifting. After the sealed garbage bag is taken out and a new garbage bag is put in, the storage block 4 is pushed back into the container 1. The power component 14 will provide suction to ensure the garbage bag adheres. At this time, the suction mainly ensures the adherence of the garbage bag, so the electric ring guide rail 1106 will not be triggered. When the garbage bag is taken out, the movable block 1102 resets under the elastic force of the damping spring 1103, the electric ring guide rail 1106 stops, and the device returns to standby mode.

[0029] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
