Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and specifically to a trash can cleaning device. Background Technology

[0002] Trash cans are daily necessities, especially in public areas. After use, stains often remain on their inner and outer walls, requiring regular collection and cleaning to reduce their environmental impact. Cleaning machines play a crucial role in this process. To prevent water accumulation inside the can after cleaning, an additional step of turning the can over is usually added before washing, by placing the trash can upside down with the opening facing downwards.

[0003] Existing trash can cleaning equipment includes trash can washing equipment that directly pushes the trash can into the container for rinsing, trash can washing equipment of the roller brush type, and trash can washing machine of the assembly line type; Among them, the garbage can washing equipment that directly pushes the garbage can into the box for rinsing has the garbage can opening facing upwards, resulting in a large amount of sewage inside the garbage can; the sewage needs to be emptied, causing the surrounding environment to become dirty and smelly, and the amount of labor involved is large; the roller brush type garbage can washing equipment needs to wash one by one, which is inefficient, and pushing and pulling is time-consuming and laborious; the assembly line type garbage can washing machine is relatively large and has poor washing effect.

[0004] Meanwhile, trash cans are typically cleaned using a combination of rotating brushes and high-pressure water guns. If they are not securely held in place, they may bounce and tilt during the cleaning process. When the high-pressure water jets are applied, the force can reach 200 to 500 kilograms, potentially causing the trash can to get caught in the equipment, posing a safety hazard. Furthermore, the trash cans are easily displaced during the cleaning process due to the rotating brushes and the impact of the high-pressure water jets. If the trash cans shift during cleaning, interference will not only affect the transfer between subsequent workstations but also reduce the cleaning effectiveness.

[0005] Therefore, there is an urgent need for a small, easy-to-install garbage can cleaning equipment that can achieve assembly line operation. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a trash can cleaning device to solve the aforementioned problems.

[0007] This invention provides the following technical solution: A trash can cleaning device, comprising: The enclosure has an opening on one side to form an inlet / outlet; A turntable is rotatably connected to the lower part of the inner cavity of the box. A central shaft is coaxially fixedly connected to the turntable, and a first cleaning roller brush is coaxially movably connected to the outer side of the central shaft. The inner cavity of the box is equipped with a second cleaning roller brush located radially outside the turntable. A bin-flipping mechanism is installed at the inlet and outlet of the container body to clamp the trash can and flip it up and down to enter and exit the container body. The upper surface of the turntable is evenly provided with multiple trays around its circumference. The trays are adapted to the lower end of the inverted trash can and are rotatably connected to the turntable with their own center as the axis. The pressure barrel mechanism includes a mounting bracket set on the upper part of the central shaft and a pressure plate hinged to the mounting bracket. A tension spring is connected between the pressure plate and the mounting bracket. The elastic force of the tension spring drives the pressure plate to flip up or down to reset. The guide plate is fixed at an angle to the top wall of the box and is located on the path of the pressure plate rotating around the central axis.

[0008] Preferably, the pressing plate is limited by the guide plate and flips downward to press down on the upper surface of the trash can during the rotation of the central shaft; the pressing plate and the tray are matched one-to-one.

[0009] Preferably, a support frame sealing plate is provided at the upper end of the central shaft, and multiple sets of turntable support frames are provided between the support frame sealing plate and the turntable, with the space between two adjacent sets of turntable support frames corresponding to a set of pressing plates and trays.

[0010] Preferably, a first driver and a second driver are installed on the top of the housing, the upper end of the central shaft is driven to the output end of the first driver, the upper end of the second cleaning roller brush is driven to the output end of the second driver, and the upper parts of the first cleaning roller brush and the upper parts of the second cleaning roller brush are driven to each other through a belt drive assembly.

[0011] Preferably, the tray is rotatably connected to the turntable via a rotating rail.

[0012] Preferably, the tray, except for the side facing away from the central axis, is turned upwards to form a limiting part.

[0013] Preferably, the tipping mechanism includes: A support frame, which is driven to flip around its upper part by a tilting bucket assembly; The bin-hanging assembly, located on the upper part of the support frame, includes a bin-hanging base, bin-hanging teeth fixed on the bin-hanging base, and a bin-hanging movable base rotatably connected to the bin-hanging base. The bin-hanging movable base is provided with an L-shaped pressure plate. The L-shaped pressure plate is flipped to press the garbage bin tightly against the support frame, and the bin-hanging teeth are used to hang the eaves of the garbage bin. The bin-retrieving assembly, located on the side wall of the support frame, is used to adhere and secure the trash can after it has been cleaned.

[0014] Preferably, the bucket retrieval assembly includes a bucket retrieval fixed base and a bucket retrieval movable base rotatably connected to the bucket retrieval fixed base, wherein a set of one or more suction cups are installed on the bucket retrieval movable base.

[0015] Preferably, a second telescopic component is installed on the bucket-retrieving fixed base, and the telescopic end of the second telescopic component is connected to the bucket-retrieving movable base.

[0016] Preferably, the tray has drainage holes.

[0017] The present invention has the following beneficial technical effects: This invention adopts a circular assembly line, which can greatly reduce the space occupied while realizing assembly line operation; the first and second drives are installed on the top of the box to avoid water affecting the drives during the washing process; cleaning rollers are installed in the center and around the turntable, which not only reduces the number of cleaning rollers, but also, in conjunction with the tray that can rotate at a certain angle, enables comprehensive cleaning of all sides of the trash can.

[0018] This invention achieves automatic opening and closing of the pressure barrel mechanism through a mechanical structure consisting of a pressure plate, a tension spring, and a guide plate. Combined with the rotational motion of a ring-shaped turntable, it avoids the high cost and susceptibility to failure associated with electromechanical structures.

[0019] During the rotation of the turntable, the pressing plate rotates and presses down under the action of the guide plate, automatically pressing the trash can. The trash can opening is inverted, and the bottom wall of the trash can does not need to be cleaned. This position is used for pressing the pressing plate, thereby avoiding affecting the cleaning effect of the trash can. As the tipping mechanism rotates the trash can 180° and moves it away from the top surface of the turntable, it simultaneously pushes the pressure plate to flip up at a certain angle, and under the action of the tension spring, the pressure plate flips up and resets.

[0020] This invention allows trash cans to enter the washing machine upside down, achieving automation—automatic entry and exit. After the trash can is tilted into the washing machine, it can detach from the tilting mechanism, providing a solution for washing trash cans on assembly lines and rotating platforms. This avoids the impact on subsequent washing caused by trash cans being unable to detach from the tilting mechanism. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Example: A type of trash can cleaning equipment, such as Figures 1-4 As shown, it includes a hollow box 100, a tipping mechanism 300, and a pressing mechanism; The box body 100 has an opening on one side to form an inlet / outlet 101, with attached... Figures 1-2 The container 100 is not fully shown to facilitate observation of its internal components; the size of the inlet and outlet 101 is adapted to the trash can 200, and a tilting mechanism 300 is installed at the inlet and outlet 101. The tilting mechanism 300 is used to rotate the trash can 200, which was originally facing upwards, by 180° so that it passes through the inlet and outlet 101 to enter and exit the container 100.

[0025] A base 51 is fixedly installed on the bottom wall of the box 100. A turntable 41 is rotatably connected above the base 51. A central shaft 42 is coaxially fixedly connected to the top of the turntable 41, and the upper end of the central shaft 42 extends to the top of the box 100.

[0026] The first driver 53 and the second driver 54 can be speed reducers and are mounted on the top of the housing 100. The output end of the first driver 53 is connected to the upper end of the central shaft 42. A first cleaning roller brush 55 is coaxially rotatably connected to the outside of the central shaft 42 via bearings. The first cleaning roller brush 55 is located opposite to the inner cavity of the housing 100. A second cleaning roller brush 56 is rotatably connected to the inner cavity of the housing 100. The first cleaning roller brush 55 and the second cleaning roller brush 56 are arranged in parallel, and the second cleaning roller brush 56 is located radially outward from the turntable 41. Figure 3 The first cleaning roller brush 55 and the second cleaning roller brush 56 are not fully shown.

[0027] The upper ends of the first cleaning roller brush 55 and the second cleaning roller brush 56 both extend to the top of the housing 100. The output end of the second driver 54 is connected to the upper end of the second cleaning roller brush 56. The upper end of the second cleaning roller brush 56 and the upper end of the first cleaning roller brush 55 are connected by a belt drive assembly 57.

[0028] Multiple trays 58 are evenly arranged around the top of the turntable 41 around its axis of rotation. Each tray 58 corresponds to a cleaning process. The tray 58 is adapted to the inverted trash can 200. Thus, the flipping mechanism 300 clamps and fixes the trash can 200, flips it 180° and onto the tray 58 on the upper surface of the turntable 41. The trash can 200 is clamped and limited by the tray 58, and then the flipping mechanism 300 releases the trash can 200.

[0029] The turntable 41 has a drainage hole and a water spray gun installed on it. The water spray gun is used to wash the inner and outer walls of the inverted trash can 200 on the turntable 41 with high pressure.

[0030] The edge of the tray 58 curves upward to form a limiting part 581. The limiting part 581 cooperates with the trash can 200 to clamp and limit the inverted trash can 200. The side of the tray 58 away from the central axis 42 does not have a limiting part 581. The tray 58 is rotatably connected to the turntable 41 around its own axis via the rotating rail 59. A power mechanism is installed at the bottom of the turntable 41. The power mechanism is used to drive the tray 58 to rotate within a set angle (e.g., 90°).

[0031] like Figures 15-18 As shown, the pressure barrel mechanism includes a turntable 41, a central shaft 42, a support frame sealing plate 45, a guide plate 46, a mounting bracket 47, a pressing plate 48, and a tension spring 49.

[0032] A support frame plate 45 (located in the inner cavity of the box 100) is fixedly installed on the upper part of the central shaft 42. Multiple sets of turntable support frames 451 are arranged evenly around the central shaft 42 between the support frame plate 45 and the turntable 41. The upper part of the turntable 41 is divided into several workstations by the multiple turntable support frames 451. Each workstation corresponds to a set of pressing barrel mechanism and a tray 58.

[0033] A mounting bracket 47 is fixedly installed below the support frame plate 45. A pressure plate 48 is hinged to the side wall of the mounting bracket 47 via a pressure shaft 482. A tension spring 49 is connected between the middle of the pressure plate 48 and the side wall of the mounting bracket 47. Each station (i.e., between two adjacent turntable support frames 451) corresponds to a set of pressure plates 48.

[0034] A guide plate 46 is fixedly installed on the bottom wall of the top plate 411. The guide plate 46 extends downward from the inner top wall of the housing 100 along the rotation direction of the turntable 41.

[0035] like Figure 18 As shown in state A1, the tension of spring 49 is at its maximum, and the pressure plate 48 cannot be suspended in a horizontal state. At this time, an upward or downward force can be applied to the pressure plate 48, so that the pressure plate 48 can be rotated upward or downward to reset.

[0036] like Figures 5-14As shown, the bucket tipping mechanism 300 includes a support frame 31, a bucket hanging assembly 32, a bucket retrieval assembly 33, and a bucket tipping assembly 34; The tipping bucket assembly 34 is fixedly installed relative to the box 200. The tipping bucket assembly 34 can be a geared motor. The output end of the geared motor is connected to the rotation shaft of the support frame 31, so that the tipping bucket assembly 34 drives the support frame 31 to flip.

[0037] like Figure 5 As shown, under normal conditions, the rotation axis of the support frame 31 is located at its upper part.

[0038] like Figure 8 As shown, the bucket hanging assembly 32 includes a bucket hanging base 321, a bucket hanging movable base 322, a pressure plate 323, a bucket hanging tooth 324, and a first telescopic assembly (not shown in the figure). The bucket hanging base 321 is fixed to the upper part of the support frame 31, and the bucket hanging movable base 322 is hinged to the upper end of the bucket hanging base 321. The bucket hanging tooth 324 has an L-shaped structure, with the horizontal end of the bucket hanging tooth 324 fixed to the upper part of the support frame 31, and the vertical end of the bucket hanging tooth 324 facing upward relative to its horizontal end. The pressure plate 323 has an L-shaped structure, and its lateral end is fixed to the movable seat 322 of the hanging bucket. Figure 8 As shown, when clamping the trash can 200, the vertical ends of the pressure plate 323 are set facing downwards; The first telescopic component can be a telescopic cylinder. The fixed end of the first telescopic component is hinged to the bucket fixing seat 321, and the telescopic end of the first telescopic component is hinged to the bucket movable seat 322. Thus, the telescopic extension of the first telescopic component pushes the bucket movable seat 322 to rotate relative to the bucket fixing seat 321 within a 90° range.

[0039] Under normal circumstances Figure 5 As shown, the bucket-retrieving assembly 33 is mounted opposite to the middle of the outer side wall of the support frame 31, as... Figure 9 As shown, the bucket retrieval assembly 33 includes a bucket retrieval fixing base 331, a second telescopic assembly 332, a bucket retrieval movable base 333, an elastic telescopic rod 334, and a suction cup 335; The bucket-retrieving fixed seat 331 is fixed to the middle of the outer side wall of the support frame 31. The bucket-retrieving movable seat 333 is hinged to the lower end of the bucket-retrieving fixed seat 331. The suction cup 335 is a vacuum suction cup. The suction cup 335 is installed on the bucket-retrieving movable seat 333 through the elastic telescopic rod 334. The suction cup 335 is made of rubber and other materials and has a certain elastic deformation ability.

[0040] The second telescopic component 332 can be a telescopic cylinder. The fixed end of the second telescopic component 332 is hinged to the bucket-retrieving fixed seat 331, and the telescopic end of the second telescopic component 332 is hinged to the bucket-retrieving movable seat 333. Thus, the telescopic extension of the second telescopic component 332 pushes the bucket-retrieving movable seat 333 to rotate relative to the bucket-retrieving fixed seat 331 within a 90° range.

[0041] Working principle: The trash can 200 with its opening facing upwards on the ground is moved to the inlet / outlet 101 of the container 100. The trash can 200 is clamped by the flipping mechanism 300 and flipped 180° to the upper surface of the turntable 41 and then released. The trash can 200 is fixed under the limit of the tray 58.

[0042] The first driver 53 drives the turntable 41 to rotate at a set angle via the central shaft 42, causing the two adjacent trays 58 to alternate positions until the turntable 41 rotates 360° back to the inlet / outlet 101. During this process, the trash can 200 goes through each process for corresponding cleaning. Then, the tipping mechanism 300 clamps the cleaned trash can 200 and rotates it 180° in the opposite direction to the ground so that the trash can opening faces upward.

[0043] The second driver 54 drives the second cleaning roller brush 56 to rotate, and drives the first cleaning roller brush 55 to rotate via the belt drive assembly 57. The rotation of the first cleaning roller brush 55 and the second cleaning roller brush 56 is used to clean the inverted trash can 200 on the turntable 41.

[0044] The first cleaning roller brush 55 and the second cleaning roller brush 56 are flexible brush bristle structures. To avoid dead corners during the cleaning process of the trash can 200, when the trash can 200 rotates between the first cleaning roller brush 55 and the second cleaning roller brush 56, the power mechanism drives the tray 58 to rotate forward and backward at a set angle and then reset. During this process, the trash can 200 rotates around itself in both forward and backward directions, so that the first cleaning roller brush 55 and the second cleaning roller brush 56 can clean the side wall of the trash can 200 without dead corners.

[0045] like Figure 6 , Figure 7 As shown, in normal conditions, the trash can 200 has its opening facing upwards. After being held in this state by the flipping mechanism 300, the trash can 200 is flipped 180° so that its opening faces downwards and is placed on the upper surface of the turntable 41.

[0046] Then, turntable 41 rotates the trash can 200 on it to the next workstation (alternating position of tray 58). During this process, the trash can 200, which was originally in an upward-folded state (such as...) Figure 18 As shown in state B, it rotates and comes into contact with guide plate 46. Continuing to rotate, guide plate 46 pushes pressure plate 48 downwards (until...). Figure 18 (As shown in state C), the clamping plate 48 flips downward so that the clamping flange 481 at its free end abuts against the upper surface of the inverted trash can 200, thereby increasing the contact area with the upper surface of the inverted trash can 200 by the clamping flange 481. The pressing plate 48 presses down on the upper surface of the inverted trash can 200 and applies pressure through the tension spring 49.

[0047] When the compressed trash can 200 is cleaned by the rotation of the first cleaning roller brush 55 and the second cleaning roller brush 56 on opposite sides, it will not shift in position, nor will it shift in position when rinsed by a high-pressure water gun.

[0048] The turntable 41 rotates once, causing the trash can 200 to pass through each station for different cleaning steps, finally returning to the inlet / outlet 101 (i.e., the position near the tipping mechanism 300). The tipping mechanism 300 then clamps the trash can 200, which has been cleaned and is in an inverted position at the initial position of the turntable 41. The tipping mechanism 300 then rotates the clamped trash can 200 180° in the opposite direction to the ground, so that its opening faces upward. During this process, the trash can 200 pushes the pressing plate 48 on its upper surface to rotate upward a certain distance, which is sufficient to cross the horizontal position (e.g., ...). Figure 18 After reaching state A1, the clamping plate 48 is flipped upwards and reset by the elastic force of the tension spring 49. This ensures that the clamping plate 48 is in the initial upward position after the trash can 200 is released.

[0049] Install the tipping mechanism 300 at the inlet / outlet 101 of the housing 100, such as... Figure 5 , Figure 6 As shown, the trash can 200 is pushed on the ground close to the inlet and outlet 101 of the container 100, so that the trash can 200 fits against the support frame 31. At this time, the lid of the trash can 200 is located on the side away from the inlet and outlet 101 of the container 100.

[0050] The process of placing the bucket includes four steps: hanging the bucket, flipping the bucket (in and out), lowering the bucket, and detaching. Hanging bucket: The first telescopic component extends and retracts, causing the pressure plate 323 to rotate as follows: Figure 8 As shown, this process is as follows Figure 11 As shown in A1 to A2, the vertical end of the pressure plate 323 presses against the inner wall of the trash can 200, thereby pressing the trash can 200 tightly against the side wall of the support frame 31. Flipping the bucket (in): The tipping assembly 34 drives the clamped trash can 200 to flip 180°, and this process is as follows: Figure 12 As shown in B1 to B2; after the trash can 200 is flipped 180°, its opening faces downward and it falls onto the upper surface of the turntable 41.

[0051] Drop into the bucket: like Figure 13 As shown, when the trash can 200 is flipped so that its opening faces downwards, it slides down a certain distance relative to the support frame 31 due to gravity, causing the trash can 200 to slide out relative to the vertical end of the hanging teeth 324, thus separating it. Simultaneously, the first telescopic component extends and retracts, causing the pressure plate 323 to rotate in the opposite direction and reset to its original position. Figure 13 As shown, the pressure plate 323 is separated from the trash can 200.

[0052] Turntable 41 drives trash can 200 to rotate and move, and then performs subsequent cleaning steps such as foaming, washing, disinfection and drying, and finally returns to the inlet and outlet 101 of container 100.

[0053] Detachment: like Figure 14 As shown, the first telescopic component extends and retracts, causing the pressure plate 323 to rotate 90°, so that the vertical end of the pressure plate 323 presses against the inner wall of the trash can 200, thereby pressing the trash can 200 tightly against the side wall of the support frame 31; at the same time, the second telescopic component 332 extends and retracts, causing the movable seat 333 to rotate 90° relative to the fixed seat 331. Figure 14 As shown, the suction cup 335 is oriented towards and adheres to the outer wall of the trash can 200, and the negative pressure of the suction cup 335 achieves adsorption and fixation to the outer wall of the trash can 200. The negative pressure of the suction cup 335 adsorbs the trash can 200, thus fixing the trash can 200 during the subsequent 180° rotation of the trash can 200 and preventing the trash can 200 from tilting.

[0054] Turning over the bucket (out): The tipping assembly 34 drives the support frame 31 to rotate 180° in the opposite direction, causing the trash can 200 to tip over from the inlet / outlet 101 of the container 100. After the trash can 200 lands, the suction cups 335 stop working and rotate 90° in the opposite direction to return to their original position and adhere to the support frame 31. The extension and retraction of the first telescopic assembly causes the pressure plate 323 to rotate 90° in the opposite direction, causing the pressure plate 323 to separate from the trash can 200.

[0055] Before hanging the bin, the rim of the bin 200 can be manually hung on the vertical end of the hanging teeth 324, or when the bin is flipped, after the bin 200 leaves the ground, it slides down a certain distance relative to the support frame 31 under the action of gravity, thereby automatically inserting the rim of the bin 200 into the vertical end of the hanging teeth 324.

[0056] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
