[0065] The self-powered intelligent trash can of this utility model is described in detail below with reference to the accompanying drawings.

[0066] Referring to Figures 1 to 6, the self-powered smart trash can provided according to the embodiments of the present invention includes a drive base 10, a bin body 20, a lifting assembly 30, and a self-powered power supply assembly 40.

[0067] The drive base 10 includes a base 11, a Z-axis drive component 12, and a sensor switch 13; the Z-axis drive component 12 is disposed inside the base 11 and is connected to the sensor switch 13; the sensor switch 13 is disposed on the outer wall of the base 11 and is used to activate the Z-axis drive component 12 when a user is sensed within a preset distance.

[0068] The base 11 is placed on the ground, and the induction switch 13 on its side wall is at a certain height from the ground. When the user's foot approaches the induction switch 13 at a preset distance, it will be detected by the induction switch 13, which will then control the Z-axis drive 12 to open. In this embodiment, the preset distance is 1 to 20 cm. That is to say, when the user needs to throw away trash, he only needs to bring one foot within 1 to 20 cm of the induction switch 13 on the base 11 to be detected by the induction switch 13, which will then control the Z-axis drive 12.

[0069] The bin body 20 includes an outer shell 21, an inner bin 22, and a lid assembly 23. The outer shell 21 is disposed above the base 11 and connected to the Z-axis drive member 12, and can move along the Z-axis direction under the drive of the Z-axis drive member 12. The inner bin 22 is movably disposed inside the outer shell 21 for collecting garbage. The lid assembly 23 is connected to the sensor switch 13 and is used to open the inner bin after the sensor switch senses a user.

[0070] The outer shell 21 of the bin 20 is connected to the Z-axis drive component 12, and the inner bin 22 is movably disposed within the outer shell 21. Therefore, when the sensor switch 13 controls the Z-axis drive component 12 to move the outer shell 21 upward, the outer shell 21 can simultaneously move the inner bin 22 upward, thus increasing the height of the inner bin 22. Consequently, when the user disposes of garbage, they are closer to the opening of the inner bin 22, i.e., closer to the disposal opening, allowing for more accurate disposal of garbage into the inner bin 22. The sensor switch 13 is also connected to the cover assembly 23, so the sensor switch 13 can automatically control the cover assembly 23 to open, thereby allowing the opening of the inner bin 22 to be opened for convenient garbage disposal by the user.

[0071] The lifting assembly 30 is disposed inside the outer shell 21 and connected to the inner tub 22 and the base 11. When the Z-axis drive member 12 drives the outer shell 21 to move upward along the Z-axis direction, the lifting assembly 30 can drive the inner tub 22 to move upward inside the outer shell 21; when the Z-axis drive member 12 drives the outer shell 21 to move downward along the Z-axis direction, the inner tub 22 can return to its original position inside the outer shell 21.

[0072] The lifting component 30 is linked with the Z-axis drive component 12. When the Z-axis drive component 12 drives the outer shell 21 to move upward, the lifting component 30 can drive the inner bucket 22 inside the outer shell 21 to move upward further. In this way, the height of the inner bucket 22 can be further increased. As a result, when the user throws garbage, he / she is closer to the opening of the inner bucket 22, that is, closer to the disposal opening. Thus, the garbage can be thrown into the inner bucket 22 more accurately.

[0073] The self-powered power supply component 40 is disposed on the outer shell 21 and is used to absorb light energy and convert light energy into electrical energy to power the Z-axis drive component 12, the induction switch 13 and the cover component 23.

[0074] In other words, the self-powered power supply component 40 can adopt a photoelectric energy storage structure, which can automatically absorb sunlight and light, convert them into electrical energy for storage, and then power the present application without requiring the user to charge it separately.

[0075] More specifically, before use, the user can place a garbage bag over the inner bin 22. When using the device, the user can place one foot 1 to 20 cm away from the sensor switch 13 on the base 11 for more than 3 seconds. At this time, the sensor switch 13 will detect the user and control the cover assembly 23 to open the inner bin 22. Simultaneously, it will control the Z-axis drive 12 to open, which will drive the outer shell 21 to move upward a certain distance and then stop, thereby increasing the height of the outer shell 21 and the inner bin 22 inside. As the height of the outer shell 21 increases, the lifting assembly 30 can drive the inner bin 22 inside the outer shell 21 to move further upward along the outer shell 21, thereby further increasing the height of the inner bin 22. In this way, the height of the opening on the inner bin 22, that is, the garbage disposal opening, from the user will decrease. This allows the user to more accurately dispose of the garbage into the inner bin 22, and correspondingly, it will be less likely to dispose of the garbage outside the inner bin 22 and fall to the ground. After the Z-axis drive unit 12 stops working for 10-15 seconds, the cover assembly 23 automatically closes the inner barrel. Simultaneously, the Z-axis drive unit 12 drives the outer shell 21 to move downwards and reset. At this time, the outer shell 21 and the inner barrel 22 also reset downwards to their original height, thus preventing the overall height of this application from being too high and easily tipped over. During this process, the self-powered power supply assembly 40 converts light energy into electrical energy for power supply, eliminating the need for additional charging. Therefore, it is more energy-efficient, environmentally friendly, and convenient to use. It should be added that this application also includes a controller, which provides simple control over the operation of various components. A simple MCU controller can be used, which is low-cost and based on existing technology, making it easy to use.

[0076] The self-powered smart trash can provided by this utility model can automatically open the trash can and raise its height to facilitate users to accurately dispose of trash into the trash can; at the same time, it can also convert light energy into electrical energy, eliminating the need for users to charge it, making it more convenient and energy-efficient to use.

[0077] Advantageously, in one embodiment of the present invention, the cover assembly 23 includes a cover plate 231 and a flip-top drive member 232;

[0078] The flip-top drive component 232 is disposed on the outer wall of the barrel body 20 and is connected to the self-powered power supply component 40;

[0079] The cover plate 231 is connected to the flip-top drive member 232 and is used to close or open the inner barrel 22 under the drive of the flip-top drive member 232.

[0080] In other words, the flip-top drive 232 can automatically drive the cover 231 to close onto the bin 20, and can also automatically open the bin 20, thus eliminating the need for manual operation by the user, which is very convenient. More specifically, the flip-top drive 232 and the cover 231 can adopt the cooperation of a drive gear and a driven gear in the prior art. Its specific structure is a common structure in the prior art, and will not be described in detail in this embodiment. Among them, the drive gear is connected to the induction switch 13. Thus, when the induction switch 13 senses the user, it can simultaneously activate the Z-axis drive 12 and activate the drive gear to rotate forward, so that the cover 231 automatically flips upward to open the trash can, making it convenient for the user to dispose of trash. Of course, after a certain period of time, such as 10 seconds, 15 seconds, or other times, the drive gear can be activated to rotate in reverse, so that the cover 231 automatically flips downward to close the trash can and prevent the spread of odors.

[0081] Advantageously, in one embodiment of the present invention, the lifting assembly 30 includes a sliding wheel 31, a fixed pulley 32, and a pull rope 33;

[0082] Two sliding grooves 211 are provided on the opposite inner walls of the outer shell 21, both of which extend vertically. The sliding wheel 31 is provided on the opposite outer walls of the inner barrel 22 and slides in cooperation with the two sliding grooves 211.

[0083] Two fixed pulleys 32 are provided, and the two fixed pulleys 32 are arranged opposite to each other on the top of the outer casing 21;

[0084] There are two pull ropes 33, which are respectively located on both sides of the inner tub 22. One end of each pull rope 33 is connected to the inner tub 22, the middle part passes over the two fixed pulleys 32 respectively, and the other end is connected to the base 11.

[0085] When the Z-axis drive 12 drives the outer shell 21 to move upward along the Z-axis direction, the base 11 can pull the pull rope 33 downward to pull the inner barrel 22 upward through the pull rope 33.

[0086] In other words, the lifting assembly 30 adopts a pulley system structure, which allows the inner bucket 22 to slide upward along the outer shell 21 very easily, thereby increasing the height of the inner bucket 22 and making it more convenient for users to dispose of garbage. Specifically, the outer wall of the inner bucket 22 is provided with sliding wheels 31, which can slide up and down along the inner wall of the outer shell 21. The pull rope 33 on the outer wall of the inner bucket 22 passes around the fixed pulley 32 at the top of the outer shell 21 and is connected to the bottom base 11. Thus, when the Z-axis drive 12 drives the outer shell 21 to move upward, the height of the fixed pulley 32 at the top of the outer shell 21 will also increase. At this time, the fixed pulley 32 will lift the pull rope 33 on the inner bucket 22 upward, thereby pulling the inner bucket 22 upward. Under the action of this pulling force, the sliding wheel 31 on the outer wall of the inner bucket 22 can slide upward in the slide groove 211, and the height of the inner bucket 22 will be further increased. This makes it easier for users to dispose of garbage more accurately into the inner bucket 22, which is beneficial to use.

[0087] Advantageously, in another embodiment of the present invention, a locking device 331 is provided at the other end of each of the two pull ropes 33;

[0088] The top of the outer casing 21 has a through hole 212 on the outer side of each of the two fixed pulleys 32. The base 11 has two slots 112 opposite to each other. The two through holes 212 and the two slots 112 are arranged vertically opposite to each other. The two pull ropes 33 pass through the two through holes 212 and the two locking pieces 331 are detachably locked in the two slots 112.

[0089] In other words, the two pull ropes 33 on the inner tub 22, after passing over the fixed pulley 32 at the top of the outer casing 21, can pass through the through hole 212 and be secured in the slot 112 on the base 11 by the locking piece 331 on the pull rope 33. This allows the pull ropes 33 to be detachably connected to the base 11, so that when the Z-axis drive unit 12 drives the outer casing 21 upward, the inner tub 22 can be pulled upward by the pull ropes 33 to further increase its height. When it is necessary to remove the inner tub 22, simply remove the locking piece 331 from the slot 112 and pull it out from the through hole 212, which is very convenient.

[0090] Advantageously, in some embodiments of the present invention, the barrel 20 further includes an annular cover 213, which is detachably disposed at the upper end of the inner barrel 22 for concealing the fixed pulley 32 and the pull rope 33.

[0091] Preferably, both the annular cover 213 and the top of the outer shell 21 are provided with magnetic components, and the annular cover 213 is detachably attached to the outer shell 21.

[0092] The annular cover 213 is generally annular in structure with a flat upper surface. It can be installed on the top surface of the outer casing 21 to cover the fixed pulley 32 and the through hole 212. This effectively blocks the fixed pulley 32 and the through hole 212. When the cover plate 231 is closed on the bin body 20, the soft rubber pad inside can abut against the upper surface of the annular cover 213 and the garbage bag, improving the sealing effect and reducing the spread of garbage odor. The annular cover 213 is magnetically attached to the outer casing 21, making it easy to install and remove. Therefore, when it is necessary to remove the inner bin 22, the annular cover 213 can be removed directly, and the pull rope 33 can be easily pulled out from the through hole 212.

[0093] Advantageously, in some embodiments of the present invention, the self-powered power supply assembly 40 includes a plurality of perovskite micro-photovoltaic panels 41 and a battery.

[0094] The plurality of perovskite micro-photovoltaic panels 41 are all inclinedly disposed on the top of the cover plate 231;

[0095] The battery is located inside the cover plate 231 and is connected to the Z-axis drive 12, the induction switch 13 and the flip-cover drive 232.

[0096] In this embodiment, four perovskite photovoltaic panels 41 are provided. The four perovskite photovoltaic panels 41 gradually extend downward from the middle position of the top of the cover plate 231 to the edge position. Thus, the four perovskite photovoltaic panels 41 have a certain tilt angle, so they can better absorb light energy for power storage during the day or at night, without the need for manual charging by the user, making them more convenient to use.

[0097] Advantageously, in some other embodiments of the present invention, a mounting groove 111 is provided in the middle of the upper surface of the base 11, and the Z-axis drive member 12 is disposed in the mounting groove 111 and connected to the outer shell 21.

[0098] In this embodiment, the Z-axis drive 12 can be a small cylinder. The cylinder rod is connected to the outer casing 21. When the induction switch 13 senses the user, the cylinder can be activated, and the outer casing 21 can be lifted upward by the cylinder rod to increase the height of the inner bucket 22. This allows the user to more accurately put the garbage into the inner bucket 22, avoiding the problem of inaccurate and repeated disposal.
