[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] This utility model provides a lifting device for cleaning trash cans.

[0052] First embodiment:

[0053] Please refer to the following: Figures 1 to 4 In the first embodiment of this utility model, the lifting device for cleaning trash cans includes:

[0054] The mounting mechanism 2 is installed on the cleaning frame 1. The mounting mechanism 2 includes a rotating device 21, a support frame 22 and a limiting member 23. The rotating device 21 is rotatably mounted on the cleaning frame 1. The bottom of the support frame 22 is fixed to one side of the rotating device 21. The limiting member 23 is installed on the other side of the rotating device 21.

[0055] Nozzle 3, which is integrated and mounted on the rotating device 21;

[0056] Drive mechanism 4, which is mounted on the top of the support frame 22;

[0057] The lifting frame 5 is installed on the driving part of the driving mechanism 4. The driving mechanism 4 is used to control the rotation and adjustment of the lifting frame 5. The lifting frame 5 has an L-shaped structure. A limiting plate 51 is fixedly provided on the top of the lifting frame 5, and a locking hook 52 is rotatably installed on the bottom of the lifting frame 5.

[0058] The locking mechanism 6 includes a second telescopic member 61, a slide 62, and a locking plate 63. The two ends of the second telescopic member 61 are fixedly connected to the lifting frame 5 and the slide 62. The slide 62 is slidably mounted on the lifting frame 5. The bottom of the locking plate 63 is fixed to the top of the slide 62, and the top of the locking plate 63 is aligned with the blocking range of the limiting plate 51.

[0059] In this embodiment, the nozzle 3 is a rotating high-pressure nozzle used to rinse the inside of the trash can body 100. The spray range is wide, making the inner wall of the trash can body 100 more thoroughly cleaned.

[0060] In this embodiment, the rotating shaft of the lifting frame 5 is located in its middle region, which effectively reduces the space required for the lifting frame 5 to flip and adjust, thereby reducing the space occupied by the equipment during application. A strong magnet is embedded in the locking hook 52. When the locking hook 52 is hung on the axle of the trash can body 100 (the axle is made of magnetic metal and can magnetically attract the strong magnet), the strong magnet causes the locking hook 52 to magnetically attract the axle of the trash can body 100, increasing the stability of the connection and preventing the trash can body 100 from falling off during flipping and lifting.

[0061] In this embodiment, the second telescopic member 61 is any one of an electric telescopic rod, a hydraulic telescopic rod, or a telescopic cylinder, used to drive the overall lifting and lowering adjustment of the slide 62 and the locking plate 63.

[0062] The installation and locking principle of the trash can body 100:

[0063] Before the trash can body 100 is installed on the lifting frame 5, the second telescopic component 61 is activated. The second telescopic component 61 drives the slide 62 and the locking plate 63 to move down as a whole, providing clearance space for the installation of the trash can body 100.

[0064] The trash can body 100 is installed on the lifting frame 5 and located at the bottom of the limiting plate 51. After installation, the second telescopic component 61 is activated. The second telescopic component 61 drives the slide 62 and the locking plate 63 to move upward as a whole and lock the top of the trash can body 100 on the limiting plate 51. Then, the locking hook 52 is manually fixed on the axle of the trash can body 100 to achieve stable locking of the trash can body 100 on the lifting frame 5 after installation, so as to prevent the trash can body 100 from loosening and deviating from the rotation range during the rotation and lifting process.

[0065] The principle behind the tilting and lifting of the trash can body (100mm):

[0066] After the trash can body 100 is stably installed on the lifting frame 5, the drive mechanism 4 is activated. The drive mechanism 4 drives the lifting frame 5 to rotate relative to the support frame 22, so that the trash can body 100 with the opening facing upwards is rotated onto the rotating device 21 and the opening faces downwards to cover the nozzle 3, so that the inside of the trash can body 100 can be rinsed upwards through the nozzle 3.

[0067] The drive mechanism 4 allows for easy control of the lifting frame 5 to rotate and lift around the support frame 22, so that the trash can body 100 installed on the lifting frame 5 can be rotated 180° and placed upside down above the rotating device 21, and covering the top of the nozzle 3, so that the nozzle 3 can clean and maintain the surface of the trash can body 100 after it is started.

[0068] A locking mechanism 6 is provided on the top of the lifting frame 5 to lock the top of the trash can body 100. The locking hook 52 can lock the axle of the trash can body 100, so that the trash can body 100 can be stably rotated and adjusted after installation, and the problem of the trash can body 100 not being able to rotate completely is avoided.

[0069] Please refer to the following: Figure 3 and Figure 4The rotating device 21 includes a rotating platform 211, a first telescopic member 212, a swing rod 213, and a connecting rod 214. The bottom of the rotating platform 211 is rotatably mounted on the cleaning frame 1. The two ends of the first telescopic member 212 are hinged to the cleaning frame 1 and one end of the swing rod 213. The other end of the swing rod 213 is hinged to the cleaning frame 1. The two ends of the connecting rod 214 are respectively hinged to one end of the swing rod 213 and the bottom of the rotating platform 211. The bottom of the support frame 22 is fixed on the rotating platform 211, and the limiting member 23 is mounted on the rotating platform 211.

[0070] In this embodiment, the first telescopic member 212 is any one of an electric telescopic rod, a hydraulic telescopic rod, or a telescopic cylinder, used to drive the rotating platform 211 to rotate relative to the cleaning frame 1, so as to facilitate the rotational adjustment of the washing surface of the garbage can body 100 after it has been lifted and overturned.

[0071] Specifically, a sufficient clearance is reserved between the bottom of the rotating platform 211 and the cleaning frame 1 to provide space for the swing adjustment of the first telescopic member 212, the swing rod 213 and the connecting rod 214.

[0072] The rotation principle is as follows: when it is necessary to control the rotation adjustment of the rotating platform 211, the first telescopic member 212 is activated. The first telescopic member 212 drives the swing rod 213 to swing. The swing rod 213 pushes the rotating platform 211 to rotate and adjust on the cleaning frame 1 through the connecting rod 214. The rotating platform 211 drives the drive mechanism 4 and the lifting frame 5 to rotate and adjust as a whole through the support frame 22. The maximum rotation angle is 90°, so as to facilitate the rotation switching of the scrubbing surface on the surface of the garbage can body 100.

[0073] Please refer to it again. Figure 2 The nozzle 3 is a wide-angle spray nozzle, which is integrated and installed in the middle of the rotating platform 211.

[0074] This allows for wide-angle water spraying to clean the trash can body 100 after it has been tilted and lifted.

[0075] Furthermore, the side of the lifting frame 5 is provided with a track groove, and the inner side of the slide 62 is provided with a roller assembly, which is inserted into the track groove and slidably connected.

[0076] Increase the stability of the lifting and lowering adjustment of the slide 62.

[0077] Please refer to it again. Figure 2The limiting member 23 includes a supporting corner member 231 and an elastic member 232. The supporting corner member 231 is hinged to the rotating platform 211, and the elastic member 232 elastically connects the rotating platform 211 and the supporting corner member 231.

[0078] The supporting corner piece 231 has a V-shaped structure. The pivot part of the supporting corner piece 231 is hinged to the top of the rotating platform 211. The supporting corner piece 231 is supported at the opening of the garbage can body 100 after it is flipped over, and corresponds to the rotation range of the garbage can lid. It provides support and limit for the garbage can lid, so as to prevent the garbage can lid from flipping over and affecting the rotation adjustment of the equipment.

[0079] The elastic element 232 is a spring structure, with its two ends respectively attached to the bottom of the rotating platform 211 and the rotating part of the supporting corner piece 231; before the trash can body 100 is flipped, the elastic element 232 pulls the supporting corner piece 231 to unfold as shown. Figure 5 The state shown in (a) facilitates the flipping of the trash can body 100.

[0080] By setting the limiting member 23, the problem of the trash can lid flipping after the trash can body 100 is flipped and lifted onto the rotating platform 211 can be effectively avoided, thereby improving the stability of the equipment flipping and operation.

[0081] Please refer to it again. Figure 2 A support rod 53 is fixedly mounted on the lifting frame 5. The support rod 53 has a U-shaped structure and faces the installation area of ​​the lifting frame 5.

[0082] Combination Figure 5 As can be seen from (a), after the trash can body 100 is installed on the lifting frame 5, the support rod 53 can provide auxiliary support for the waist of the trash can body 100, further increasing the stability when the lifting frame 5 drives the trash can body 100 to rotate and adjust.

[0083] The working principle of the lifting device for cleaning trash cans provided in this embodiment is as follows:

[0084] A1. First, install the trash can body 100 that needs to be cleaned onto the lifting frame 5, with the top of the trash can body 100 abutting against the bottom of the limiting plate 51.

[0085] A2, activate the second telescopic component 61, the second telescopic component 61 drives the slide 62 and the locking plate 63 to move upward, the locking plate 63 is inserted into the top of the trash can body 100, so that the top of the trash can body 100 is stably abutted against the limiting plate 51.

[0086] Manually flip the locking hook 52 upward and hang it on the axle of the trash can body 100. The strong magnetic block on the locking hook 52 is attached to the axle of the trash can body 100, so that the bottom of the trash can body 100 is locked by the locking hook 52.

[0087] A3, start the drive mechanism 4, the drive mechanism 4 drives the lifting frame 5 to rotate 180° as a whole, the lifting frame 5 drives the locked trash can body 100 to rotate and invert onto the rotating platform 211, so as to facilitate the flipping and lifting of the trash can body 100 for inverted cleaning;

[0088] A4. When it is necessary to rotate and switch the brushing surface of the trash can body 100, the first telescopic component 212 is activated. The first telescopic component 212 drives the swing rod 213 to swing. The swing rod 213 pushes the rotating platform 211, the support frame 22, the drive mechanism 4, the lifting frame 5, and the locked trash can body 100 to rotate through the connecting rod 214, so as to switch the brushing surface of the trash can.

[0089] In an optional embodiment of the above embodiments, the drive mechanism 4 can directly adopt a dual-axis motor, which facilitates direct drive of the rotation adjustment of the lifting frame 5.

[0090] Second embodiment:

[0091] Please refer to the following: Figures 6 to 8 Based on the first embodiment of this utility model providing a lifting device for cleaning trash cans, the second embodiment of this utility model proposes another lifting device for cleaning trash cans. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0092] Specifically, the difference in the lifting device for garbage can cleaning provided in the second embodiment of this utility model is that two elastic retractable members 221 are embedded and installed on the top of the support frame 22, the drive mechanism 4 includes a mounting cover 41, a drive motor 42, and a docking device 43, the bottom of the mounting cover 41 abuts against the top of the support frame 22, the top of the elastic retractable members 221 is fixedly connected to the bottom of the mounting cover 41, the drive motor 42 is slidably mounted on the support frame 22 through a moving mechanism 7, and the rotating shaft of the lifting frame 5 passes through the mounting cover 41 and is rotatably connected. A first connecting disk 54 is fixedly mounted on the rotating shaft. The docking device 43 includes a second connecting disk 431, a first protrusion 432, a slip ring 433, and a second protrusion 434. One end of the second connecting disk 431 is fixedly connected to the drive shaft of the drive motor 42, and the other end of the second connecting disk 431 abuts and engages with the first connecting disk 54. The top of the first protrusion 432 is fixedly mounted on the mounting cover 41. The slip ring 433 is fixedly mounted on the second connecting disk 431 and slides in contact with the first protrusion 432. The second protrusion 434 is fixedly mounted on the bottom of the slip ring 433.

[0093] When the first connecting disk 54 and the second connecting disk 431 are engaged, the second protrusion 434 and the first protrusion 432 are misaligned; when the first connecting disk 54 and the second connecting disk 431 are separated, the second protrusion 434 and the first protrusion 432 are in the same rotation range.

[0094] In this embodiment, the elastic contraction member 221 is a spring contraction tube structure, and at least two are provided. On the one hand, it is used to maintain the stability of the connection between the mounting cover 41 and the support frame 22, and on the other hand, it supports the up-and-down shaking and reset between the two, so as to ensure the overall stability of the equipment operation.

[0095] in, Figure 6 and Figure 7 The second protrusion 434 shown is located at the bottom of the slip ring 433, while the lifting frame 5 is in a flipped and lifted state; it can be understood that the trash can body 100 is in a flipped state, thus ensuring that the movement and adjustment of the second protrusion 434 relative to the first protrusion 432 will not affect each other.

[0096] In this embodiment, the first connecting plate 54 is provided with a slot structure, and the second connecting plate 431 is provided with a locking block structure. When the first connecting plate 54 and the second connecting plate 431 abut and engage, the locking block structure is inserted into the slot structure, so that the first connecting plate 54 and the second connecting plate 431 can abut and engage stably, ensuring the stability of the drive motor 42 driving the first connecting plate 54 to rotate through the second connecting plate 431, thereby ensuring the stability of the garbage can body 100 when it is lifted and flipped.

[0097] In this embodiment, when the drive shaft end of the drive motor 42 is used for vibration adjustment, one rotation cycle is 360°. This ensures that after the drive motor 42 drives the slip ring 433 and the second protrusion 434 to rotate via the second connecting plate 431, the second protrusion 434 can maintain a certain position after stopping. Figure 6 The state shown.

[0098] The drive motor 42 includes two operating modes:

[0099] Flip mode, such as Figure 8 As shown, the second connecting plate 431 abuts and engages with the first connecting plate 54; the second protrusion 434 and the first protrusion 432 are misaligned and not in the same rotation range; the drive motor 42 is used to drive the lifting frame 5 to rotate and adjust so that the garbage bin body 100 can be lifted and rotated after being loaded.

[0100] jitter mode, such as Figure 10 As shown, the second connecting plate 431 is separated from the first connecting plate 54, and the second protrusion 434 and the first protrusion 432 are within the same rotation range. The drive motor 42 is used to control the first protrusion 432, the mounting cover 41 and the lifting frame 5 to shake up and down as a whole.

[0101] The moving mechanism 7 is used to switch the operating mode of the drive motor 42.

[0102] Mode switching principle:

[0103] When the garbage bin body 100 rotates and feeds the material to the support range of the rotating platform 211, the moving mechanism 7 is activated. The moving mechanism 7 drives the drive motor 42 to move to the left. The drive motor 42 causes the second connecting plate 431 to separate from the first connecting plate 54. At the same time as separation, the second connecting plate 431 also drives the slip ring 433 and the second protrusion 434 to move to the left. The second protrusion 434 moves to the docking range of the first protrusion 432. The drive motor 42 is then activated. The drive motor 42 only drives the second connecting plate 431 to rotate, and the second connecting plate 431 no longer drives the first connecting plate 54 to rotate. The connecting plate 431 drives the second protrusion 434 to rotate via the slip ring 433. When the second protrusion 434 rotates, it abuts against the first protrusion 432, causing the first protrusion 432 to be squeezed by the second protrusion 434 and generate an upward displacement. During the process of the second protrusion 434 separating from the first protrusion 432, the first protrusion 432 and the mounting cover 41 as a whole adaptively move downward under the action of the elastic contraction member 221 and gravity. This process is repeated. When the second protrusion 434 continues to rotate, it provides the first protrusion 432 with the power to shake up and down, which facilitates the up and down shaking of the trash can during the rinsing process and improves the quality of trash can cleaning.

[0104] Please refer to it again. Figure 6 The support frame 22 has an adjustment groove 220 on its top. The moving mechanism 7 includes a third telescopic member 71, a mounting frame 72, and a sliding shaft 73. The third telescopic member 71 is fixedly connected to the support frame 22 and the mounting frame 72. The sliding shaft 73 passes through the mounting frame 72 and is fixedly connected to the support frame 22. The third telescopic member 71 and the sliding shaft 73 are both located within the adjustment groove 220. The top of the mounting frame 72 is located within the mounting cover 41. The bottom of the drive motor 42 is fixedly mounted on the top of the mounting frame 72.

[0105] In this embodiment, the third telescopic member 71 is any one of an electric telescopic rod, a hydraulic telescopic rod, or a telescopic cylinder, used to directly drive the mounting bracket 72 to move and adjust on the support frame 22. The sliding shaft 73 provides stable support and limiting function for the movement and adjustment of the mounting bracket 72, thereby ensuring the stability of the movement and adjustment of the drive motor 42.

[0106] The third telescopic component 71 facilitates the stable sliding adjustment of the mounting bracket 72 on the top of the support frame 22. When the mounting bracket 72 moves, it synchronously drives the drive motor 42 to move and adjust, thereby providing stable support and limiting for the movement of the drive motor 42.

[0107] Please refer to the following: Figure 6 and Figure 8 The first connecting plate 54 has a limiting groove 540. The lifting device for cleaning the trash can also includes a limiting rod 8. One end of the limiting rod 8 is fixedly connected to the mounting frame 72. The limiting rod 8 has an L-shaped structure. The other end of the limiting rod 8 is aligned with the limiting groove 540.

[0108] When the limiting slide bar 8 is not inserted into the limiting slide groove 540, the first connecting plate 54 can drive the lifting frame 5 to rotate and adjust on the mounting cover 41;

[0109] When the limiting slide bar 8 is inserted into the limiting slide groove 540, the first connecting plate 54 cannot drive the lifting frame 5 to rotate and adjust on the mounting cover 41, so as to maintain the stability of the lifting frame 5 after flipping and adjusting.

[0110] During the process of the drive motor 42 switching from the flipping mode to the shaking mode, the mounting bracket 72 synchronously drives the limiting slide rod 8 to move to the left and insert into the range of the limiting slide groove 540, forming a limit on the first connecting plate 54, so that the first connecting plate 54, the mounting cover 41 and the lifting frame 5 as a whole cannot be flipped and adjusted relative to the support frame 22, but can only shake up and down relative to each other.

[0111] On the one hand, it ensures the stability of the lifting frame 5 after it is flipped, preventing it from flipping over; on the other hand, it provides stable sliding support for the up-and-down shaking of the lifting frame 5.

[0112] During the process of the drive motor 42 switching from the shaking mode to the flipping mode, the mounting bracket 72 synchronously drives the limiting slide rod 8 to move to the right. The limiting slide rod 8 disengages from the range of the limiting slide groove 540 and separates from the first connecting plate 54, so that the second connecting plate 431 abuts and engages with the first connecting plate 54. This facilitates the control of the drive motor 42 to rotate and adjust the second connecting plate 431, the first connecting plate 54, and the lifting frame 5 as a whole relative to the mounting cover 41, so as to facilitate the flipping and reset of the trash can after cleaning.

[0113] This is so that while the working mode of the drive motor 42 is switched, the first connecting plate 54 can be locked and limited to maintain the stability of the lifting frame 5 after it is flipped up and down.

[0114] The working principle of the lifting device for cleaning trash cans provided in this embodiment is as follows:

[0115] S1, the drive motor 42 is in the flip adjustment mode, and the trash can body 100 is rotated and inverted onto the rotating platform 211 in advance. The trash can body 100 is rinsed by the nozzle 3. At the same time, the limiting slide groove 540 is aligned with the movement range of the limiting slide rod 8.

[0116] S2, combined Figure 8 and Figure 10 The third telescopic component 71 is activated, which drives the mounting bracket 72 to move to the left. The drive motor 42 moves to the left, and the second connecting plate 431, the slip ring 433, and the second protrusion 434 move to the left as a whole. This causes the drive motor 42 to switch from rotation mode to shaking mode. At the same time, the mounting bracket 72 also drives the limiting slide rod 8 to move to the left and insert into the range of the limiting slide groove 540, forming a sliding limit on the first connecting plate 54. This maintains the stability of the lifting frame 5's overall up-and-down shaking in shaking mode and prevents the lifting frame 5 from swinging left and right when shaking.

[0117] S3, combined Figure 11 (a) to Figure 11 (b) to Figure 11 (c) to Figure 11 In step (d), during the shaking cleaning process, the drive motor 42 is activated, which drives the second connecting plate 431, the slip ring 433, and the second protrusion 434 to rotate. During the rotation of the second protrusion 434, it intermittently abuts against the first protrusion 432, causing the first protrusion 432, the mounting cover 41, and the lifting frame 5 to be intermittently lifted. The shaking can shake off some of the attached substances on the inner wall of the trash can, thereby achieving the purpose of shaking cleaning and improving cleaning efficiency and quality.

All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
