Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste bins, and in particular to a kitchen waste bin with a washable guide plate. Background Technology

[0002] With the continuous acceleration of urbanization and the continuous improvement of people's living standards in my country, the amount of kitchen waste generated is also increasing. Efficient and hygienic treatment of kitchen waste has become an important issue for urban management and community life. Currently, the kitchen waste collection equipment commonly used in residential communities, office buildings, and other public places is mostly traditional open or pedal-operated trash cans.

[0003] Existing food waste bins have several shortcomings in use. First, when residents dispose of garbage, spilled food, oil, and other easily contaminated waste cans can easily pollute the bin's inlet and guide plate. These residues not only breed bacteria and produce unpleasant odors, affecting environmental hygiene, but also attract insects, becoming a source of disease transmission. Second, to ensure cleanliness, maintenance personnel need to frequently clean the bins manually. This process is not only time-consuming and labor-intensive, increasing labor costs, but the cleaning effect is also difficult to guarantee, especially during peak periods when timely cleaning may be impossible.

[0004] Furthermore, traditional trash cans are limited in function and lack intelligent management tools. Managers cannot remotely monitor the overflow status or collected weight of the trash cans, relying solely on scheduled inspections, which is inefficient and unable to achieve precise scheduling and collection, easily leading to problems such as trash overflow or uneven distribution of collection resources.

[0005] Therefore, there is an urgent need for a new type of kitchen waste bin that can automatically keep the feeding area clean and hygienic, and can achieve intelligent monitoring and management, in order to solve the problems of poor hygiene, difficult cleaning and maintenance, and low management efficiency in existing technologies. Utility Model Content

[0006] The purpose of this invention is to provide a kitchen waste bin with a washable guide plate to overcome the shortcomings of the prior art.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0008] A kitchen waste bin with a washable guide plate includes a bin shell with a feeding port at the top. A guide plate is installed on the feeding port, opening and closing it. When the guide plate is closed, waste is placed on its upper surface; when open, waste falls from the feeding port. A garbage bin is placed inside the bin shell, located below the feeding port. A cleaning unit is also installed inside the bin shell, comprising a cleaning pipe, a cleaning switch, and a water spray nozzle. One end of the cleaning pipe is connected to an external high-pressure water source, and the other end is connected to the water spray nozzle. The cleaning switch is installed on the cleaning pipe to control the flow of water within it. The water spray nozzle faces the upper surface of the guide plate.

[0009] Further improvements to optimize the technical solution include:

[0010] The smart bin is installed on the upper part of the aforementioned trash can shell. The smart bin contains a controller, which is connected to the cloud via a wireless signal. A top plate is installed on the top of the trash can shell, and a camera is installed on the top plate. The camera is used to capture images of the upper surface of the guide plate. The camera is connected to the controller and can transmit the captured video to the controller, which then transmits the video to the cloud.

[0011] The aforementioned top plate is equipped with a lighting lamp, which is used to illuminate the upper surface of the guide plate.

[0012] The aforementioned garbage bin shell has mounting brackets fixed on both the left and right sides of the feeding port. Each mounting bracket is equipped with a guide plate tilting motor. The guide plate includes a left plate and a right plate. The left end of the left plate and the right end of the right plate are respectively hinged to the left and right mounting brackets. At the same time, the drive shafts of the two guide plate tilting motors are respectively connected to the corresponding left and right plates. The guide plate tilting motors can drive the corresponding left and right plates to rotate, thereby enabling the guide plates to open and close. The guide plate tilting motors are connected to a controller, which can control the operation of the guide plate tilting motors.

[0013] Both the left and right sides of the aforementioned plate are equipped with upwardly extending baffles.

[0014] The aforementioned cleaning tube is fixed to the mounting bracket by connecting pins.

[0015] The bottom of the aforementioned trash can shell is equipped with a weighing plate, on which the trash can is placed, and the weighing plate is connected to a controller.

[0016] An overflow sensor is installed on the upper part of the aforementioned trash can shell. The overflow sensor faces the trash can and is used to sense the height of the trash inside the trash can. The overflow sensor is connected to the controller.

[0017] A human body sensor is installed on the front of the aforementioned trash can shell. The human body sensor is used to detect whether a person is approaching the trash can shell and is connected to the controller.

[0018] The aforementioned smart box has a display screen on its front side, which is connected to a controller. The controller can send received signals to the display screen for display.

[0019] The technical advantages of this utility model are as follows:

[0020] 1. This utility model, by setting up a cleaning unit consisting of a cleaning pipe, a cleaning switch, and a water spray nozzle, with the water spray nozzle directly facing the upper surface of the guide plate, can achieve automatic and efficient rinsing of the working area. This can promptly remove residual oil, soup, and other dirt, fundamentally avoiding the problems of bacteria growth, odor generation, and attracting insects due to dirt accumulation, greatly improving the environmental hygiene of the trash can and its surroundings, while significantly reducing the maintenance costs and labor intensity of manual cleaning.

[0021] 2. This utility model provides hardware support for an intelligent identification and control system by adding a camera, controller, and guide plate tilting motor. The operating logic of the intelligent identification and control system is as follows: waste must first be placed on the guide plate, the camera captures the image, and the controller (or cloud) identifies and judges it; only when it is confirmed to be kitchen waste will the controller instruct the motor to open the guide plate to complete the disposal. This mechanism effectively prevents the misdisposal of non-kitchen waste from the source, greatly improves the accuracy and purity of waste sorting, and reduces the burden and cost of back-end sorting.

[0022] 3. This utility model integrates sensors such as weighing, overflow sensing, and human body sensing, and connects to the cloud, enabling managers to remotely and in real-time monitor key data such as the fullness of the garbage bins, collected weight, and disposal frequency. It realizes a precise scheduling model for garbage collection from "scheduled collection" to "on-demand collection," optimizes the allocation of human and vehicle resources, significantly reduces operating costs, and improves management efficiency.

[0023] 4. The lighting ensures clear camera recognition at night or in low light conditions. A human body sensor enables automatic wake-up and standby of the device. The display screen can be used to show classification information, disposal results, or promotional slogans. These features collectively enhance user interactivity and play a positive guiding and educational role in cultivating residents' correct waste sorting habits. Attached Figure Description

[0030] Obviously, the accompanying drawings described below are merely some examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without any inventive effort. Furthermore, it is understood that although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content disclosed in this application, any changes to design, manufacturing, or production based on the technical content disclosed in this application are merely conventional technical means and should not be construed as insufficient disclosure of the content of this application.

[0031] like Figures 1 to 4 As shown, this utility model provides an intelligent kitchen waste bin with a washable guide plate, which mainly includes a waste bin shell 1, a guide plate 2, a waste bin 3, a cleaning unit 4, and an intelligent control system.

[0032] The main structure of the garbage bin shell 1 is made of stainless steel, with a feeding port 11 at the top for disposing of garbage. The inner cavity of the shell is used to house the garbage bin 3, which is located directly below the feeding port 11 and is used to collect the kitchen waste that eventually falls in.

[0033] The guide plate 2 is hinged to the feed inlet 11, and its core function is to temporarily store and identify waste. In this embodiment, the guide plate 2 preferably consists of two parts: a left plate 21 and a right plate 22, simulating a "double door" structure. The left end of the left plate 21 and the right end of the right plate 22 are respectively hinged to the mounting brackets 14 fixed on the left and right sides of the feed inlet 11 via pivots. To prevent waste, especially liquids, from flowing out from the sides during temporary storage, upward-extending baffles 24 are provided on the front and rear sides of both the left plate 21 and the right plate 22.

[0034] The opening and closing action of the guide plate 2 is driven by the guide plate flipping motor 23. Each mounting bracket 14 is equipped with a guide plate flipping motor 23, and its drive shaft is connected to the corresponding left plate 21 or right plate 22 rotating shaft through a coupling or directly. After receiving a signal, the motor 23 rotates forward or reverse, thereby driving the left and right plates to flip, thus realizing the opening and closing of the guide plate 2.

[0035] The cleaning unit 4 is used for automatically cleaning the upper surface of the guide plate 2. It includes a cleaning pipe 41, a cleaning switch 42, and a water spray nozzle 43. One end of the cleaning pipe 41 is connected to an external high-pressure water source (such as a municipal water pipe or a water pump connected to an internal water tank), and the other end is connected to the water spray nozzle 43. The water spray nozzle 43 is a fan-shaped nozzle, and the cleaning switch 42 is a normally closed solenoid valve installed on the cleaning pipe 41, used to control the opening and closing of the pipeline after receiving an electrical signal. The cleaning pipe 41 can be fixed to the mounting bracket 14 by fasteners such as connecting pins to maintain a stable position.

[0036] The intelligent functions of this utility model are realized by an intelligent control system, the core components of which are integrated into the intelligent box 5 installed on the upper part of the garbage bin shell 1.

[0037] The intelligent box 5 contains a controller, which can be a PLC, microcontroller, or embedded system, serving as the brain of the entire system. The controller connects to a cloud server via a wireless communication module to achieve remote data transmission.

[0038] A top plate 12 is installed above the garbage bin shell 1, on which a camera 17 and a light 13 are mounted. The lens of the camera 17 faces downwards, directly towards the upper surface of the guide plate 2, for capturing images of garbage placed on the guide plate 2. The light 13 automatically turns on when there is insufficient light, providing supplementary lighting for the camera 17 to ensure the clarity of the captured images. The camera 17 is electrically connected to the controller, transmitting the captured video stream or image data to the controller.

[0039] In addition, a weighing plate 15 is installed at the bottom of the garbage bin shell 1, on which the garbage bin 3 is placed. The weighing plate 15 is connected to the controller, which can monitor the weight of the garbage in the bin in real time and upload the data. An overflow sensor 16 is installed on the upper inner wall of the garbage bin shell 1. The overflow sensor 16 can be an ultrasonic or infrared ranging sensor, with its sensing head facing the inside of the garbage bin 3, to detect the height of the garbage pile inside the bin and prevent garbage from overflowing. A human body sensor 18 is also installed at the front of the garbage bin shell 1. The human body sensor 18 can be an infrared pyroelectric sensor, used to detect whether someone is approaching, thereby waking up the system to enter standby mode and saving energy.

[0040] The front side of the smart bin 5 also features a display screen that connects to the controller. This screen can be used to display the weight of the waste, its overflow status, information about waste sorting, or the system's operating interface.

[0041] The workflow of this utility model is as follows:

[0042] When the human body sensor 18 detects someone approaching, it transmits a signal to the controller, which then wakes up the system and can turn on the lighting 13 to provide supplementary lighting for the camera 17.

[0043] The user places the waste on the closed guide plate 2. Camera 17 immediately captures an image of the waste and transmits the image data to the controller. The controller uses built-in or cloud-connected AI algorithms to analyze the image in real time and determine whether it is kitchen waste.

[0044] If the waste is identified as kitchen waste: the controller sends a command to the two guide plate flipping motors 23, which drive the left plate 21 and right plate 22 to flip outward and open, allowing the waste to fall from the feeding port 11 into the waste bin 3 below. After the waste is disposed of, the motor reverses, and the guide plate 2 closes.

[0045] If the waste is identified as non-kitchen waste: the controller will not execute the command to open the feeder plate, but can control the display screen to issue a prompt to guide the user to dispose of the waste correctly.

[0046] Automatic cleaning: After the guide plate 2 completes one opening and closing action, or is triggered by the controller at a time, the controller will send a brief start signal to the cleaning switch 42. High-pressure water will instantly spray out from the spray nozzle 43 through the cleaning pipe 41 to automatically rinse the upper surface of the guide plate 2 and remove residual dirt.

[0047] Data Upload and Management: Throughout the process, the weighing plate 15 records the weight change after each disposal, and the overflow sensor 16 continuously monitors the height inside the bin. All this data, along with the identification results and disposal time, is uploaded by the controller to the cloud management platform via wireless network. Managers can remotely monitor the status of each waste bin, achieving precise and efficient waste collection scheduling.

[0048] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
