[0002] The existing garbage classification teaching aids have a relatively simple structure. Generally, they are simulated garbage bins with a structure of four garbage bins, several cards with specific garbage written on them, and a garbage classification chart corresponding to the simulated garbage bins. After putting the cards representing different garbage into different simulated garbage bins, the cards are compared with the correct classification instructions in the garbage classification chart to confirm whether the corresponding garbage classification is correct, so as to learn the relevant knowledge of garbage classification.

[0003] In the prior art, for example, the Chinese utility model patent with the application number 201820776091.1 discloses a garbage classification learning device, including a bottom plate. Two or more notches are provided on the bottom plate, and barrel bodies simulating and replacing real garbage bins of different classifications are embedded in the notches. A column is provided on the bottom plate, a cross plate is provided above the column, and a learning plate is provided at the cross plate above the notch. The learning content of a kind of garbage classification is respectively provided on the plate surfaces of the learning plates. A control circuit board, a sounding device and a power supply with voice information pre-set and matching the learning content on the plate surface are provided in the plate bodies of the learning plates. A triggering device is respectively connected to the control circuit boards in the learning plates; by using simulated utensils to represent actual garbage classification garbage bins, garbage classification knowledge is displayed through patterns and characters, and at the same time, garbage classification knowledge can be played synchronously through voice, and through vivid demonstrations, children can understand and clearly know all processes and influences after garbage classification, improving the learning efficiency and effect of children.

[0004] However, the teaching methods of the above-mentioned existing garbage classification teaching aids have the following technical problems: First, the awareness rate of classification is poor and the intuitiveness is insufficient, and the feedback of the garbage classification result cannot be obtained in real time, resulting in insufficient knowledge acquisition rate of garbage classification teaching; second, the interest of the garbage classification teaching aid is insufficient, and students are not actively involved. Therefore, there is an urgent need for a garbage classification teaching aid that can not only effectively train and guide garbage classification, but also combine education with entertainment, so as to more effectively enable people to understand and be familiar with the specific classification of garbage, guide people to make accurate placements, and improve the garbage treatment efficiency of the whole society. Summary of the Utility Model

[0005] To solve the technical problems existing in the prior art, the present application provides a garbage classification teaching aid that uses RFID identification technology to quickly identify and display the garbage classification result and has high interest.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A garbage classification teaching aid, comprising a base, in which a plurality of card slots are opened, and corresponding simulated trash cans are arranged in the card slots. The simulated trash can includes a barrel body and a cover body rotatably connected to the upper opening of the barrel body. A servo motor is fixedly connected to the inner wall of the upper opening of the barrel body, and a rotating plate is fixedly connected to the output shaft of the servo motor. The servo motor can drive the rotating plate to rotate to open the cover body; a power supply component, a speaker component, a storage module, a control module and an RFID identification module are arranged in the base; it also includes a simulated garbage card, which includes a card body, a garbage pattern arranged on the card body, and an RFID tag embedded in the card body; when the simulated garbage card is identified by the RFID identification module, the control module controls the cover body of the corresponding simulated trash can to open and controls the speaker component to play the garbage classification information stored in the storage module.

An electrode sleeve is fixedly embedded at the bottom of the card slot, and an electrode post is fixedly embedded on the lower end surface of the barrel body. The electrode post can be inserted into the electrode sleeve. The electrode sleeve is electrically connected to the power supply component, and the electrode post is electrically connected to the servo motor.

[0009] Preferably, a garbage classification label is arranged on the barrel body of each simulated trash can.

[0010] Preferably, an indicator light is embedded in the base in front of each simulated trash can. The indicator light is electrically connected to the power supply component. When the cover body of the simulated trash can is opened, the corresponding indicator light lights up.

[0011] Preferably, a receiving cavity is opened on the base, and a flip cover that can cover the receiving cavity is rotatably connected to the base at the receiving cavity.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] By setting the RFID identification module and the corresponding RFID tag, when the simulated garbage card with the RFID tag is brought close to the RFID identification module, the garbage corresponding to the simulated garbage card can be quickly identified. The controller module will control the speaker component to automatically voice broadcast the name of the garbage corresponding to the simulated garbage card and the garbage classification to which it belongs; by setting the servo motor, the cover body of the simulated trash can can be automatically opened. Thus, after identifying the classification of the garbage corresponding to the simulated garbage card, the control module can control the corresponding servo motor to open the cover body of the corresponding simulated trash can, allowing the user to put the simulated garbage card into the simulated trash can, simulating the garbage classification and putting process.

[0014] In the present utility model, a simulated trash can with an automatically opening lid increases the entertainment of garbage classification. At the same time, with automatic voice broadcast, the names and classifications of items are clear, which not only deepens the impression of children but also facilitates the use of children who cannot read. During the interesting use, users can learn the classification of various items and develop the habit of putting garbage in the right category. BRIEF DESCRIPTION OF THE DRAWINGS
