AI Technical Summary
In existing trash can cleaning machines, the uneven overlap between the cleaning brush and the side wall of the trash can leads to poor cleaning results. Too large an overlap results in high resistance, while too small an overlap results in incomplete cleaning.
The machine adopts a lifting bin washing design. By installing an inner and outer frame, and using a horizontal elastic reset component and telescopic component, the overlap area between the side wall of the trash can and the cleaning brush is kept within a set range. The bin is flipped and the tray is positioned by the bin tipping component. Combined with the lifting component and rotating cleaning brush, a thorough cleaning is performed.
It improves the cleaning effect on the side walls of the trash can, achieving all-round cleaning of the trash can and avoiding problems such as incomplete cleaning or excessive resistance caused by uneven contact between the cleaning brush and the side walls of the trash can.

Abstract
Description
Technical Field
[0001] This invention relates to the field of cleaning equipment technology, specifically to a lifting drum washing machine. 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 machines typically involve the trash can rotating around a cleaning brush. For example, the "Intelligent Cleaning Machine and Cleaning Method for Trash Can Cleaning" disclosed in patent number CN119368529A adopts a four-station circular layout and a synchronous turntable structure. The trash can is automatically flipped and loaded through the cooperation of the upper and lower bin mechanism, the elastic support mechanism and the rotating bracket. The conveying mechanism drives the trash can to enter the foam, cleaning, disinfection and drying stations in sequence. Each station can operate in parallel, improving the overall processing continuity. However, the trash can rotates around the cleaning brush. In order to achieve cleaning, the bristles of the cleaning brush need to be able to brush all the side walls of the trash can. Since the trash can is a square structure, the overlap area between the bristles of the cleaning brush and different parts of the same side wall of the trash can varies. If the overlap area is too large, it will cause too much resistance to the bristles and reduce the cleaning effect. If the overlap area is too small, it will not be conducive to cleaning. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a lifting drum washing machine to solve the aforementioned problems.
[0005] This invention provides the following technical solution: A lifting-type bin washing machine includes a first cleaning brush horizontally mounted on an outer mounting frame. An inner mounting frame is horizontally movably connected to the outer mounting frame, moving closer to or further away from the first cleaning brush. A horizontally elastic reset member is provided between the outer mounting frame and the inner mounting frame. A support frame is vertically movably connected to the inner mounting frame via a lifting assembly. A second cleaning brush is vertically mounted on the inner mounting frame. A tray is rotatably connected to the support frame, aligning with an opening of the second cleaning brush. A bin-flipping assembly is mounted on the outer mounting frame, used to flip the bin so that its opening faces downwards and places it on the tray.
[0006] Preferably, the bucket-tilting assembly includes a support frame, a rotary power assembly, a bucket-fixing pressure plate, a bucket-moving pressure plate, and a third telescopic assembly. The support frame is driven by the rotary power assembly to flip up and down on one side of the mounting frame. The bucket-fixing pressure plate is fixed to the upper edge of the support frame. The bucket-moving pressure plate is driven by the third telescopic assembly to move closer to or further away from the bucket-fixing pressure plate on the side wall of the support frame.
[0007] Preferably, the support frame is hinged to a bottom plate away from the lower edge of the hanging bucket fixing plate, and a fourth telescopic component is connected between the bottom plate and the side wall of the support frame.
[0008] Preferably, the upper surface of the base plate that contacts the trash can is provided with several serrations.
[0009] Preferably, it also includes a lateral movement assembly disposed on the mounting frame, the lateral movement assembly being used to push the inner mounting frame to move horizontally on the mounting frame.
[0010] Preferably, the lateral movement assembly includes a first telescopic assembly and a second telescopic assembly with different strokes, and the movable ends of the first telescopic assembly and the second telescopic assembly are both in contact with the inner frame; wherein, the first telescopic assembly is used to push the inner frame to the position of carrying the trash can, and the second telescopic assembly is used to push the inner frame to move the long side or short side of the trash can on it to a set position.
[0011] Preferably, a rotating platform is mounted on the top of the mounting frame, and a pressure plate is mounted on the output end of the rotating platform facing the tray.
[0012] The present invention has the following beneficial technical effects: The present invention allows the trash can to rotate around the cleaning brush. During the rotation of the trash can, the second telescopic component and the lateral elastic reset component work together to ensure that the area of overlap between the trash can sidewalls of different lengths and the cleaning brush is within a set value range, thereby improving the cleaning effect of the cleaning brush on the trash can sidewalls. This invention uses a lifting mechanism to clean the inner and outer bins of a trash can; the inner frame is movable relative to the outer frame, allowing it to move back and forth to adapt to the contact surface between the cleaning brush and the trash can.

[0016] 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.
[0017] Example: A type of lifting drum washing machine, such as Figures 1-9 As shown, it includes an outer mounting frame 1, an inner mounting frame 2, a lateral elastic reset component 3, a lateral movement component 4, a tipping bucket component 5, a first cleaning brush 6, a power component 7, a second cleaning brush 71, and a lifting component 8; The outer frame 1 is fixed relative to the ground. The inner frame 2 is linearly connected to the outer frame 1 in the horizontal direction through a guide rail or other guiding mechanism. A transverse elastic reset member 3 is provided between the upper and lower ends of the outer frame 1 and the inner frame 2. The transverse elastic reset member 3 can be a structure such as a tension spring. The elastic force of the transverse elastic reset member 3 pushes the inner frame 2 to approach the first cleaning brush 6 on the outer frame 1. The first cleaning brush 6 is horizontally set and rotatably connected to the middle of the side wall of the outer frame 1, and the first cleaning brush 6 is driven to rotate by the corresponding power component; the lower part of the inner frame 2 is provided with a support frame 21 by the lifting component 8. The lifting component 8 can be a telescopic cylinder or an electric telescopic rod, etc., and the support frame 21 is located inside the outer frame 1. The support frame 21 has at least one opening, and a tray 22 is rotatably connected to the opening. The second cleaning brush 71 is vertically installed inside the outer frame 1. The second cleaning brush 71 is driven to rotate by the power component 7, and each second cleaning brush 71 corresponds exactly to one of the openings of the support frame 21. like Figure 1 As shown, the first cleaning brush 6 is positioned opposite each other on the middle of the rear side wall of the mounting frame 1, and the bucket tilting assembly 5 is positioned opposite each other on the front side wall of the mounting frame 1. The bucket tilting assembly 5 includes a support frame 51, a rotary power assembly 52, a bucket fixing plate 53, a bucket movable plate 54, and a third telescopic assembly 55. The support frame 51 is driven by the rotary power assembly 52 to tilt up and down on the front side wall of the mounting frame 1. Figure 4 As shown, under normal conditions, the hanging bin fixing plate 53 is fixed to the upper edge of the support frame 51. The hanging bin movable plate 54 is driven by the third telescopic component 55 to move up and down on the front side wall of the support frame 51, approaching or moving away from the hanging bin fixing plate 53. The lower edge of the support frame 51 is hinged to a base plate 57, and the two ends of the fourth telescopic component 56 are respectively hinged to the base plate 57 and the side wall of the support frame 51. The upper surface of the base plate 57 that contacts the garbage bin 100 is provided with two parallel serrations 58. Both the third telescopic assembly 55 and the fourth telescopic assembly 56 can be telescopic cylinders.
[0018] A transverse movement assembly 4 is installed on the top of the outer frame 1. The transverse movement assembly 4 includes a first telescopic assembly 41 and a second telescopic assembly 42 arranged side by side with different extension strokes. The fixed ends of the first telescopic assembly 41 and the second telescopic assembly 42 are fixed to the top of the outer frame 1, and the movable ends of the first telescopic assembly 41 and the second telescopic assembly 42 abut against the inner frame 2.
[0019] like Figure 9 As shown, a rotating platform 9 is installed on the top of the mounting frame 1. The output end of the rotating platform 9 is set towards the side of the corresponding tray 22. A pressure plate 91 is installed on the output end of the rotating platform 9. The lower surface of the pressure plate 91 is serrated to increase the friction between it and the trash can 100.
[0020] Working principle: Move the trash can 100 to be cleaned to the tipping assembly 5, as follows: Figure 1As shown in the lower right, the trash can 100 is positioned above the base plate 57 and is attached to the support frame 51. Then, the fourth telescopic component 56 is controlled to shorten, causing the base plate 57 to rotate upward to a horizontal state, so that the serrations 58 on the upper surface of the base plate 57 abut against the bottom of the trash can 100, greatly increasing the friction and preventing it from separating. like Figure 6 As shown, the third telescopic component 55 extends, causing the movable pressure plate 54 of the hanging bucket to move upward and approach the fixed pressure plate 53 of the hanging bucket. During this process, the movable pressure plate 54 of the hanging bucket is inserted upward relative to the eaves of the garbage can 200, and the fixed pressure plate 53 of the hanging bucket is fastened to the inner wall of the garbage can. Both the movable pressure plate 54 and the fixed pressure plate 53 of the hanging bucket have an L-shaped structure. The movable pressure plate 54 and the fixed pressure plate 53 of the hanging bucket cooperate to clamp and fix the garbage can 200 from above and below.
[0021] After the trash can 200 is clamped and fixed, the rotating power component 52 drives the support frame 51 to rotate 180°, so that the trash can 100 flips upward 180° so that its opening faces downward and is placed on the tray 22. The opening side of the trash can 100 is adapted to the tray 22, thereby limiting the downward-facing trash can 100. Then the flipping component 5 separates from the trash can 100.
[0022] Previously, the first telescopic component 41 (at which time the second telescopic component 42 is in a shortened state) extends and pushes the inner mounting frame 2, which is in contact with the tipping component 5, to move closer to the tipping bin 100, which is beneficial for connecting the tipped bin 100.
[0023] The cross-section of the trash can 100 is a rectangular outline of varying lengths, not a square. During cleaning, it has two states: First, both the first telescopic component 41 and the second telescopic component 42 are in a shortened state. Under the action of the lateral elastic reset component 3, the inner mounting frame 2 is pushed closer to the first cleaning brush 6. At this time, the first cleaning brush 6 contacts the side wall of the short side of the trash can 100. When the second telescopic component 42 (at this time, the first telescopic component 41 is in a shortened state) extends, it pushes the inner mounting frame 2, which is in contact with the tipping component 5, by a set distance. At this time, the first cleaning brush 6 contacts the side wall of the long side of the trash can 100.
[0024] The first cleaning brush 6 is set parallel to the side wall of the trash can 100, which is conducive to thorough cleaning and improves the cleaning effect. The rotation of the tray 22 causes the trash can 100 to rotate accordingly, thereby controlling each outer side wall of the trash can 100 to contact the first cleaning brush 6 in turn. The lifting assembly 8 first raises the support frame 21, causing the top of the inverted trash can 100 to abut against the pressure plate 91. Then, the rotating platform 9 rotates the trash can 1001 through the friction between the pressure plate 91 and the trash can 100. The tray 22 can also rotate automatically.
[0025] The lifting component 8 drives the support frame 21 to descend, causing the first cleaning brush 6 to move relative to the height direction of the trash can 100 for comprehensive cleaning, and the second cleaning brush 71 to extend into the inside of the trash can 100 for cleaning.
[0026] 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.
