An automatically pushable public garbage can and control device

Abstract

This invention provides an automatically pushing public trash can and its control device, including a main frame and several pushing trash cans. The main frame includes an upper cover, connectors, and an outer trash can cylinder. The main frame protects the inner cylinder of the public trash can from damage by the roadside environment. Several pedal boxes are opened on the front of the outer trash can, allowing manual control of the lifting and pushing of the trash cans. Several pushing trash cans are arranged inside the outer trash can, each including an inner cylinder, a pushing mechanism, and a lifting mechanism. The lifting mechanism includes a lever, a lifting rod assembly, and two diamond-shaped connecting rod assemblies. The up-and-down swing of the front end of the lever can drive the pushing mechanism to push the inner cylinder out. At the same time, the bottom of the inner cylinder can be lifted by the diamond-shaped connecting rod assemblies, causing the inner cylinder to flip over, making it easy to empty the trash inside. This improves the cleaning efficiency of sanitation workers and reduces the labor cost of manually emptying trash.

Description

Technical Field

[0001] This invention belongs to the field of public trash cans, and specifically relates to an automatically pushable public trash can and its control device. Background Technology

[0002] Garbage pollution primarily originates from the odors and dripping water emitted during the decomposition of easily decomposable organic matter in the garbage. People are increasingly concerned about garbage disposal, and garbage bins are essential tools for maintaining the urban environment and an important component of the city's appearance, reflecting a society's level of civilization. The pollution from garbage bins mainly comes from the odors and dripping water emitted during the decomposition of easily decomposable organic matter in the garbage. The intensity of the odor is greatly related to the amount of dripping water, the timing of garbage collection, and the season. High temperatures or long-term accumulation can easily lead to odors. In the high temperatures of summer, if not cleaned promptly, it will cause a strong stench and a large amount of dripping water. When the release is excessive, it can have a certain impact on the environment within a 10-meter radius, causing discomfort and affecting people's quality of life. Contact with waste can easily cause environmental pollution and spread diseases.

[0003] Currently, trash cans are collected manually on a regular basis. In the past, sanitation workers would remove the lids of the trash cans and then manually empty the trash into them, which was not only time-consuming and laborious but also a waste of a lot of energy.

[0004] Therefore, how to provide a public trash can and control device that can automatically flip over to empty the trash, so as to improve the cleaning efficiency of sanitation workers, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the aforementioned technical problems, in a first aspect, the present invention provides an automatically pushable public trash can, comprising: a main frame, the main frame including an upper cover, a connector, and an outer trash cylinder, the upper cover being fixed to the top of the outer trash cylinder via the connector; a plurality of pedal boxes being provided on the front of the outer trash cylinder; a plurality of pushable trash cans being arranged inside the outer trash cylinder, adjacent pushable trash cans being separated by partitions, the number of pushable trash cans being adapted to the number of pedal boxes; wherein each pushable trash can includes an inner cylinder, a pushing mechanism, and a lifting mechanism; the pushing...

The top of the inner cylinder is rotatably connected to the top of the pushing platform. The lifting mechanism includes a lever, a lifting rod assembly, and two diamond-shaped connecting rod assemblies. The rear end of the lever is fixedly connected to the lifting rod assembly, the middle part of the lever is rotatably connected to the bottom surface of the outer garbage cylinder through a rotating shaft support, and the front end of the lever is located inside the pedal box. One end of each of the two diamond-shaped connecting rod assemblies is rotatably connected to the lifting rod assembly, and the other end of each diamond-shaped connecting rod assemblies is rotatably connected to the two sides of the bottom of the inner cylinder.

[0006] In the first aspect, the lifting rod assembly includes a first crossbar, a second crossbar, and a support rod; the rear end of the lever is fixedly connected to one end of the first crossbar; the first crossbar and the second crossbar are fixedly connected via the support rod to form an I-shaped structure; one end of each of the two rhomboid connecting rod assemblies is rotatably connected to both ends of the second crossbar, and the other end of each of the two rhomboid connecting rod assemblies is rotatably connected to the inner cylinder. The rotatable connections between the inner cylinder and the lifting rod assembly, and between the inner cylinder and the rhomboid connecting rod assemblies, are both located on the same side of the inner cylinder.

[0007] In the first aspect, the pushing platform includes a base plate and a vertical plate connected in an L-shape. A third crossbar is provided at the top of the vertical plate. The top of the front side of the inner cylinder is rotatably connected to the third crossbar. The inner cylinder is placed on the base plate, and the size of the inner cylinder is adapted to the size of the L-shaped structure. The front side of the inner cylinder is the side where the inner cylinder fits against the vertical plate. Both slide rails include an inner rail and an outer rail. The two inner rails are respectively fixedly connected to the two sides of the base plate, and the ends of the two outer rails away from the vertical plate are fixedly connected to the first crossbar.

[0008] In the first aspect, the rhomboid linkage assembly includes a first link, a second link, a third link, and a fourth link. The two ends of the first link are rotatably connected to one end of the second link and one end of the fourth link, respectively. The two ends of the third link are rotatably connected to the other ends of the second link and the fourth link, respectively. The rotatable connection between the first link and the second link is rotatably connected to the end of the second crossbar, and the rotatable connection between the third link and the fourth link is rotatably connected to the bottom of the inner cylinder.

[0009] In the first aspect, the distance between the front end of the lever and the pivot point is greater than the distance between the rear end of the lever and the pivot point; wherein the pivot point is the rotatable connection between the lever and the pivot support.

[0010] In the first aspect, the pedal box is rotatably connected to the outer garbage bin, and the front end of the lever is fixedly connected to the pedal box so that the front end of the lever moves up and down with the pedal box.

[0011] In the first aspect, the pedal box is fixedly connected to the outer garbage can, a gravity sensor is provided on the top surface of the pedal box, a telescopic cylinder is provided inside the pedal box, and the extended end of the telescopic cylinder is connected to the front end of the lever to drive the front end of the lever to move up and down.

[0012] In the first aspect, the upper cover is provided with a solar panel, and the solar panel, the gravity sensor, and the telescopic cylinder are communicatively connected.

[0013] Secondly, a control device for an automatically pushable public trash can, characterized in that the control device comprises:

[0014] The automatically pushed public trash can described in Example 1;

[0015] The controller includes a memory and a processor. The memory stores a computer program, which, when executed by the processor, performs the following steps:

[0016] In the initial state, the telescopic rod of the control telescopic cylinder extends to a first preset telescopic length so that the front end of the lever remains in a horizontal state;

[0017] The pushing platform and slide rail are in a horizontal position, so that both the inner cylinder and the pushing platform are located inside the outer garbage cylinder;

[0018] The pressure value of the pedal box is detected in real time by a gravity detector;

[0019] The pressure value is obtained and it is determined whether the pressure value reaches the preset start-up pressure threshold.

[0020] If the pressure value reaches the preset start-up pressure threshold, the telescopic cylinder is controlled to retract to the second preset telescopic length, so that the front end of the lever swings downward, thereby driving the rear end of the lever to lift upward, so that the pushing platform and the slide rail are in an inclined state. The pushing platform slides out of the outer garbage cylinder along the slide rail, the bottom of the inner cylinder is lifted by the diamond-shaped connecting rod group, and the top of the inner cylinder rotates along the pushing platform, so that the inner cylinder flips over.

[0021] Within a preset time period, the extension and retraction amount of the telescopic rod is maintained at the second preset extension and retraction length;

[0022] At time t1, the pressure value is acquired and it is determined whether the pressure value reaches the preset start-up pressure threshold. Time t1 is any time after the extension and retraction of the telescopic rod has maintained the second preset extension and retraction length within a preset time period.

[0023] If the pressure value does not reach the preset start-up pressure threshold, the telescopic cylinder is controlled to extend its telescopic rod to the first preset telescopic length so that the front end of the lever returns to a horizontal state, thereby causing the rear end of the lever to swing downwards until the pushing platform and the slide rail return to a horizontal state. The pushing platform slides back into the interior of the outer garbage cylinder along the slide rail so that the inner cylinder returns to its original position.

[0024] In the second aspect, the automatically pushable public trash can also includes a locking threshold, the bottom of which is rotatably connected to the bottom of the outer trash can, and the two sides of which are detachably connected to the outer trash can via pins;

[0025] When the computer program is executed by the processor, it can also perform the following steps:

[0026] When the telescopic rod of the telescopic cylinder retracts to the second preset telescopic length, the telescopic rod's extension amount during the current time period is obtained, and it is determined whether the extension amount has reached the third preset telescopic length.

[0027] When the extension amount is lower than the third preset extension length, it is determined that the push process of the push platform is resisted by the locking threshold during the current time period;

[0028] Stop the retraction of the telescopic cylinder's telescopic rod;

[0029] The telescopic cylinder extends its telescopic rod to a first preset telescopic length so that the front end of the lever remains horizontal.

[0030] Beneficial Effects: This invention proposes an automatically pushable public trash can, comprising a main frame and several pushable trash cans. The main frame includes an upper cover, connectors, and an outer trash can cylinder. Since the device provided in this application is a public trash can placed on the street, the upper cover and outer trash can cylinder protect the inner cylinder of the public trash can from damage by the roadside environment. Several pedal boxes are opened on the front of the outer trash can cylinder, allowing sanitation workers to automatically push the trash cans by stepping on the pedal boxes. Each pushable trash can includes an inner cylinder, a pushing mechanism, and a lifting mechanism. The pushing mechanism includes two slide rails and a pushing platform. The slide rails facilitate pushing the pushing platform outward when the front end of the lever is pressed down, thereby connecting the pushing platform with the inner cylinder. The inner cylinder, connected to the lifting mechanism, is flipped out. The lifting mechanism includes a lever, a lifting rod assembly, and two diamond-shaped connecting rod assemblies. The rear end of the lever is fixedly connected to the lifting rod assembly, and the front end of the lever is located inside the pedal box. The two diamond-shaped connecting rod assemblies are rotatably connected to the lifting rod assembly and the bottom of the inner cylinder, respectively. Since the top and bottom of the inner cylinder are constrained, when the lever swings back and forth and drives the pushing platform to push the inner cylinder out, as the length of the pushing platform slides out increases, the top of the inner cylinder is rotated and fixed. At this time, the top of the inner cylinder rotates along the pushing platform, and the diamond-shaped connecting rod assemblies hold the bottom of the inner cylinder and lift it up, realizing the flipping of the inner cylinder. This allows the garbage in the inner cylinder to be easily poured out, thereby improving the efficiency of sanitation workers in cleaning up garbage and reducing the labor cost of sanitation workers manually emptying garbage.

[0044] Example 1:

[0045] Please see Figure 1-3This embodiment provides an automatically pushable public trash can, which includes: a main frame 1, the main frame 1 including an upper cover 3, a connector 4, and an outer trash cylinder 5, the upper cover 3 being fixed to the top of the outer trash cylinder 5 via the connector 4; several pedal boxes 6 being provided on the front of the outer trash cylinder 5; several pushable trash cans 2, which are arranged inside the outer trash cylinder 5, and adjacent pushable trash cans 2 are separated by partitions 7, the number of pushable trash cans 2 being adapted to the number of pedal boxes 6; wherein, each pushable trash can 2 includes an inner cylinder 8, a pushing mechanism 9, and a lifting mechanism 10; the pushing mechanism 9 includes two slide rails 11 to... The push platform 12 has two slide rails 11 located on both sides of the bottom of the push platform 12 and slidably connected to both sides of the bottom of the push platform 12. The top of the inner cylinder 8 is rotatably connected to the top of the push platform 12. The lifting mechanism 10 includes a lever 13, a lifting rod assembly 14, and two rhomboid connecting rod assemblies 15. The rear end of the lever 13 is fixedly connected to the lifting rod assembly 14, and the middle part of the lever 13 is rotatably connected to the bottom surface of the outer garbage cylinder 5 through a pivot support 16. The front end of the lever 13 is located inside the pedal box 6. One end of each of the two rhomboid connecting rod assemblies 15 is rotatably connected to the lifting rod assembly 14, and the other end of each of the two rhomboid connecting rod assemblies 15 is rotatably connected to both sides of the bottom of the inner cylinder 8.

[0046] Specifically, the present invention provides an automatically pushable public trash can, comprising: a main frame 1 and several pushable trash cans 2. The main frame 1 includes an upper cover 3, a connector 4, and an outer trash can 5. Since the device provided in this application is a public trash can placed on the side of a street, the upper cover 3 and the outer trash can 5 protect the inner tube of the public trash can from damage by the roadside environment (such as wind, rain, and debris). The connector 4 is also provided; as an option, the connector 4 can be a cigarette extinguisher for easy use by passersby. Several pedal boxes 6 are provided on the front of the outer trash can 5, allowing sanitation workers to automatically push the pushable trash cans 2 by stepping on the pedal boxes 6. Each pushable trash can 2 includes an inner tube 8, a pushing mechanism 9, and a lifting mechanism 10. The pushing mechanism 9 includes two slide rails 11 and a pushing platform 12. The slide rails 11 facilitate pushing the pushing platform 12 outward when the front end of the lever 13 is pressed down, thereby rotating the pushing platform 12 and the lifting mechanism 10. The inner cylinder 8 is flipped out; the lifting mechanism 10 includes a lever 13, a lifting rod assembly 14, and two rhomboid connecting rod assemblies 15. The rear end of the lever 13 is fixedly connected to the lifting rod assembly 14, and the front end of the lever 13 is located inside the pedal box 6, allowing sanitation workers to control the front end of the lever 13 to press down by stepping on the pedal box 6, thereby raising the rear end of the lever 13, driving the slide rail 11 to slide and the lifting rod assembly 14 to lift; at the same time, the two rhomboid connecting rod assemblies are rotatably connected to the lifting rod assembly 14 and the bottom of the inner cylinder 8, respectively. The top and bottom of the inner cylinder 8 are respectively constrained. When the lever 13 swings back and forth and drives the push platform 12 to push the inner cylinder 8 out, as the length of the push platform 12 slides out increases, the top of the inner cylinder 8 is rotated and fixed. At this time, the top of the inner cylinder 8 rotates along the push platform 12, and the diamond-shaped connecting rod group 15 holds the bottom of the inner cylinder 8 and lifts it up, so that the inner cylinder 8 can be flipped over, making the garbage in the inner cylinder 8 easy to pour out. In this way, the efficiency of sanitation workers in cleaning up garbage is improved and the labor cost of sanitation workers manually pouring out garbage is reduced.

[0047] Since there are several push-to-dispose trash cans 2, as an achievable method, this application can select multiple trash can types such as recyclable waste, non-recyclable waste, or hazardous waste commonly found in daily life for disposal; the inner cylinder 8 is designed with durable and corrosion-resistant stainless steel material, and the same standard trash can specifications and dimensions as those of trash inner cylinders on the market are selected: the inner cylinder 8 has a capacity of 80L and dimensions of 520*480*660mm.

[0048] In some possible implementations, the lifting rod assembly 14 includes a first crossbar 17, a second crossbar 18, and a support rod 19; the rear end of the lever 13 is fixedly connected to one end of the first crossbar 17; the first crossbar 17 and the second crossbar 18 are fixedly connected through the support rod 19 to form an I-shaped structure; one end of each of the two rhomboid connecting rod assemblies 15 is rotatably connected to both ends of the second crossbar 18, and the other end of each of the two rhomboid connecting rod assemblies 15 is rotatably connected to the inner cylinder 8.

[0049] Specifically, such as Figure 4-6 As shown, the diamond-shaped connecting rod group 15 and the slide rail 11 are connected simultaneously by the first crossbar 17, the second crossbar 18 and the support rod 19, so as to drive the diamond-shaped connecting rod group 15 and the slide rail 11 to rise and fall.

[0050] In some possible implementations, the push platform 12 includes a base plate 20 and a vertical plate 21 connected to each other in an L-shaped structure. A third crossbar 22 is provided at the top of the vertical plate 21. The top of the inner cylinder 8 is rotatably connected to the third crossbar 22. The inner cylinder 8 is placed on the base plate 20. The size of the inner cylinder 8 is adapted to the size of the L-shaped structure. Both slide rails 11 include an inner rail and an outer rail. The two inner rails are fixedly connected to the two sides of the base plate 20 respectively. The ends of the two outer rails away from the vertical plate 21 are fixedly connected to the first crossbar 17.

[0051] Specifically, such as Figure 7 As shown, the push platform 12 includes a base plate 20 and a vertical plate 21 connected in an L-shape. When in use, the inner cylinder 8 is placed on the base plate 20 of the push platform and is rotatably connected to the top of the inner cylinder 8 through the vertical plate 21, which constrains and fixes the top of the inner cylinder 8, thereby realizing the function of lifting the bottom of the inner cylinder 8 when the push platform 12 slides out.

[0052] In some possible implementations, the rhomboid linkage 15 includes a first link 23, a second link 24, a third link 25, and a fourth link 26. The two ends of the first link 23 are rotatably connected to one end of the second link 24 and one end of the fourth link 26, respectively. The two ends of the third link 25 are rotatably connected to the other ends of the second link 24 and the fourth link 26, respectively. The rotatable connection between the first link 23 and the second link 24 is rotatably connected to the end of the second crossbar 18, and the rotatable connection between the third link 25 and the fourth link 26 is rotatably connected to the bottom of the inner cylinder 8.

[0053] Specifically, such as Figure 6As shown, a rhombus structure is formed by bolting together a first connecting rod 23, a second connecting rod 24, a third connecting rod 25, and a fourth connecting rod 26 of the same length. The two outer ends of the rhombus structure are rotatably connected to the second crossbar 18 and the bottom of the inner cylinder 8, respectively. When the inner cylinder 8 slides out with the push platform 12, the rhombus structure can be pulled and extended to lift and lower the bottom of the inner cylinder 8, thereby achieving the constraint function of flipping and retracting the inner cylinder 8.

[0054] In some possible implementations, the rotatable connection between the inner cylinder 8 and the third crossbar 22 and the rotatable connection between the inner cylinder 8 and the third connecting rod 25 are both located on the front side of the inner cylinder 8, which is the side of the inner cylinder 8 that is in contact with the vertical plate 21.

[0055] Specifically, such as Figure 4 As shown, in this application, the upper and lower constraint points of the inner cylinder 8 are both set on the same side. Compared with setting the connection point between the inner cylinder 8 and the rhomboid connecting rod assembly 15 on the rear side, this arrangement will allow the rhomboid connecting rod assembly 15 to lift the bottom of the inner cylinder 8 at a larger lifting angle, which is more convenient for the inner cylinder 8 to be flipped and lifted.

[0056] In some possible implementations, the distance between the front end of the lever 13 and the pivot point 27 is greater than the distance between the rear end of the lever 13 and the pivot point 27; wherein, the pivot point 27 is the rotatable connection between the lever 13 and the pivot support 16.

[0057] Specifically, such as Figure 5 As shown, since this application uses an 80L inner cylinder 8, the maximum mass that a single inner cylinder 8 can bear is about 80kg. Therefore, considering the maximum overall weight of the inner cylinder 8, the pivot point 27 is set near the rear end of the lever 13 to achieve the effect of saving effort.

[0058] In some possible implementations, the pedal box 6 is rotatably connected to the outer garbage bin 5, and the front end of the lever 13 is fixedly connected to the pedal box 6 so that the front end of the lever 13 moves up and down with the pedal box 6.

[0059] Specifically, considering that the public trash can is placed on the street, after studying the environment and the daily habits of most sanitation workers in collecting garbage, different automatic garbage pushing and starting methods can be adopted for different road sections. When the public trash can provided in this application is a manual starting method for pushing and flipping the trash can without electricity, the pedal box 6 and the outer garbage cylinder 5 are set to rotate. Its function is similar to that of common automatic flip-top trash cans. Sanitation workers can step on the pedal box 6 to make the front end of the lever 13 press down with the pedal box 6, and then the rear end of the lever 13 is lifted, which drives the slide rail 11 and the pushing platform 12 to slide out, thereby realizing the function of flipping the inner cylinder 8.

[0060] In some possible implementations, the pedal box 6 is fixedly connected to the outer garbage cylinder 5, a gravity sensor is provided on the top surface of the pedal box 6, and a telescopic cylinder is provided inside the pedal box 6. The telescopic rod of the telescopic cylinder is connected to the front end of the lever 13 to drive the front end of the lever 13 to move up and down.

[0061] Specifically, when the public trash can provided in this application adopts an electric automatic control to start the trash can pushing and flipping, the pedal box 6 and the outer trash can 5 are fixedly connected. At the same time, the top surface of the pedal box 6 is equipped with a gravity sensor. When the pedal box 6 detects the corresponding pressure, it activates the telescopic cylinder to push the front end of the lever 13 to swing up and down, reducing the pressure on sanitation workers to manually step on the pedal.

[0062] In some possible implementations, the upper cover 3 is equipped with a solar panel, and the solar panel, gravity sensor, and telescopic cylinder are connected in communication.

[0063] Specifically, considering the outdoor setting of the public trash cans involved in this application, solar panels are also installed to provide sustainable power to the gravity sensor and the telescopic cylinder.

[0064] Example 2:

[0065] This invention provides a control device for an automatically pushed public trash can, characterized in that the control device comprises:

[0066] The automatically pushed public trash can described in Example 1;

[0067] The controller includes a memory and a processor. The memory stores a computer program, which, when executed by the processor, performs the following steps:

[0068] In the initial state, the telescopic rod of the control telescopic cylinder extends to a first preset telescopic length so that the front end of the lever remains in a horizontal state;

[0069] The pushing platform and slide rail are in a horizontal position, so that both the inner cylinder and the pushing platform are located inside the outer garbage cylinder;

[0070] The pressure value of the pedal box is detected in real time by a gravity detector;

[0071] The pressure value is obtained and it is determined whether the pressure value reaches the preset start-up pressure threshold.

[0072] If the pressure value reaches the preset start-up pressure threshold, the telescopic cylinder is controlled to retract to the second preset telescopic length, so that the front end of the lever swings downward, thereby driving the rear end of the lever to lift upward, so that the pushing platform and the slide rail are in an inclined state. The pushing platform slides out of the outer garbage cylinder along the slide rail, the bottom of the inner cylinder is lifted by the diamond-shaped connecting rod group, and the top of the inner cylinder rotates along the pushing platform, so that the inner cylinder flips over.

[0073] Within a preset time period, the extension and retraction amount of the telescopic rod is maintained at the second preset extension and retraction length;

[0074] At time t1, the pressure value is acquired and it is determined whether the pressure value reaches the preset start-up pressure threshold. Time t1 is any time after the extension and retraction of the telescopic rod has maintained the second preset extension and retraction length within a preset time period.

[0075] If the pressure value does not reach the preset start-up pressure threshold, the telescopic cylinder is controlled to extend its telescopic rod to the first preset telescopic length so that the front end of the lever returns to a horizontal state, thereby causing the rear end of the lever to swing downwards until the pushing platform and the slide rail return to a horizontal state. The pushing platform slides back into the interior of the outer garbage cylinder along the slide rail so that the inner cylinder returns to its original position.

[0076] Specifically, regarding the step of controlling the extension rod of the telescopic cylinder to extend to a first preset extension length in the initial state, so as to keep the front end of the lever in a horizontal state, such as... Figure 1-3As shown, the initial state is that the public trash can is in the trash disposal state, that is, the inner cylinder is placed vertically on the pushing platform and located inside the outer trash cylinder. At this time, the lever should be in a horizontal state, so the telescopic rod of the telescopic cylinder should be extended to the first preset telescopic length. The first preset telescopic length is the amount of extension that the telescopic rod should have when the lever is in a horizontal state. When sanitation workers need to automatically push the inner cylinder out, they can automatically push the trash can by stepping on the pedal box. When the gravity detector detects in real time that the pressure value of the pedal box reaches the preset start pressure threshold, the telescopic rod of the telescopic cylinder is controlled to retract to the second preset telescopic length, so that the front end of the lever swings downward. The second preset telescopic length is the amount of extension that the telescopic rod should have when the front end of the lever is pressed down and the rear end of the lever is raised, causing the slide rail to tilt, the pushing platform drives the inner cylinder to slide out, and the inner cylinder flips to its maximum extent. Since various uncertain situations can easily occur in the trash can, such as When garbage is broken or residual garbage adheres to the inner wall of the cylinder, sanitation workers may need to clean up any remaining garbage inside the inner cylinder during the garbage collection process. Therefore, during a preset time period—the period when sanitation workers are cleaning up residual garbage—the extension of the telescopic rod should be maintained at a second preset extension length. This ensures that the inner cylinder remains in a bottom-turned state during this preset time period, facilitating the cleaning of residual garbage by sanitation workers. After the sanitation workers finish collecting garbage, i.e., after the preset time period, the pressure value is obtained, and it is determined whether the pressure value has reached a preset start-up pressure threshold. If not, the telescopic rod of the telescopic cylinder is controlled to extend to a first preset extension length, so that the front end of the lever returns to a horizontal state, allowing the inner cylinder and the pushing platform to return to the inside of the outer garbage cylinder, restoring the initial state. In this way, the efficiency of sanitation workers in cleaning up garbage is improved, and the labor cost of manually emptying garbage is reduced, even under the influence of various factors that may arise during outdoor garbage collection.

[0077] In some possible implementations, the automatically pushable public trash can further includes a locking threshold, the bottom of which is rotatably connected to the bottom of the outer trash can, and the two sides of which are detachably connected to the outer trash can via pins.

[0078] When the computer program is executed by the processor, it can also perform the following steps:

[0079] When the telescopic rod of the telescopic cylinder retracts to the second preset telescopic length, the telescopic rod's extension amount during the current time period is obtained, and it is determined whether the extension amount has reached the third preset telescopic length.

[0080] When the extension amount is lower than the third preset extension length, it is determined that the push process of the push platform is resisted by the locking threshold during the current time period;

[0081] Stop the retraction of the telescopic cylinder's telescopic rod;

[0082] The telescopic cylinder extends its telescopic rod to a first preset telescopic length so that the front end of the lever remains horizontal.

[0083] Specifically, since the public trash can is placed outdoors, to prevent unauthorized personnel from accidentally stepping on the pedal box and causing the trash can to automatically push and tip over, the automatically pushing public trash can is also equipped with a locking threshold. Sanitation workers can collect trash after opening the latch, preventing malicious use of the automatically pushing public trash can. When the telescopic cylinder retracts to the second preset telescopic length, the telescopic rod's extension amount during the current time period is obtained, and it is determined whether the extension amount has reached the third preset telescopic length. The third preset telescopic length is: the retraction of the telescopic rod causes the front end of the lever to press down until the pushing platform... The sliding and rotation of the lever are restricted by the resistance of the locking threshold, which prevents the front end of the lever from pressing down further. This means that when the extension of the lever is less than the third preset extension length, the pushing platform is still inside the outer garbage bin. Therefore, when the extension of the lever is less than the third preset extension length, it can be determined that the sanitation worker has not unlocked the locking threshold, and the person stepping on the pedal box is likely an unrelated person. Therefore, the extension of the lever is stopped and the extension cylinder is extended to the first preset extension length, so that the front end of the lever remains horizontal and the inner bin returns to its original position.
