Electronic automatic hand dryer educational teaching aid for children

Abstract

The invention discloses an electronic automatic hand dryer educational teaching aid for children. The electronic automatic hand dryer educational teaching aid for children is characterized in that thePCB is provided with four connecting circular holes; the PCB uses eight nylon columns; the front surface is connected with a two-way nylon column with the diameter of 3MM and the length of 24MM on the back surface by using a nylon column with screws with the diameter of 3MM, the length of 18MM and the top end length of 6MM to penetrate through four round holes in the edge of the PCB, so that thecircuit board is fixed in the middle; the back two-way 24MM nylon column is connected with the bottom plate and is connected with the machine tooth screw with the diameter of 3MM; the tail end of thelong 18MM nylon column is connected with a top plate and is connected with a 3MM machine tooth screw; the bottom plate is provided with interface grooves with specific shapes, and two long side platesand two short side plates are respectively arranged; the long side plates and the short side plates are directly clamped into the corresponding interface grooves in the bottom plate through the corresponding bulge parts; the top plate is provided with interface grooves with a specific shape; the top plate is directly clamped into the corresponding bulge parts of the long side plate and the shortside plate through the corresponding interface grooves; and the bottom plate, the side plates and the top plate are all made of transparent acrylic materials. The invention has the beneficial effectsthat the design principle is novel, the structure is unique, the debugging is convenient, the learning is integrated, the commercial prospect is very wide, the relevant technical blank can be filled up, and greater social benefits and economic benefits can be generated.

Description

technical field [0001] The invention relates to the field of electronic teaching aids, in particular to an electronic automatic hand dryer educational teaching aid for children. Background technique [0002] Relying on a variety of electronic teaching aids, with the educational purpose of developing creative hands and creating brainstorming, the educational concept of innovation in thinking and creation in action is introduced to cultivate and develop children's abilities. The teaching mode of "thinking in music" is different from the traditional teaching method of quantifying children's evaluation with scores. [0003] At present, educational electronic teaching aids have single functions, fewer types, high packaging level, and the electronic devices are soldered on the circuit board, so students cannot manually plug and debug. However, there are few highly flexible and pluggable modular electronic teaching aids at present. . [0004] In order to solve technical bottlenec...

AI Technical Summary

Problems solved by technology

[0003] At present, educational electronic teaching aids have single functions, fewer types, high packaging level, and the electronic devices are soldered on the circuit board, so students cannot manually plug and debug. However, there are few highly flexible and pluggable modular electronic teaching aids at present.

[0004] In order to solve technical bottlenecks such as relatively backward design level, difficult debugging, and poor training effect of the existing electronic teaching aids, the present invention discloses an electronic automatic hand dryer educational teaching aid for children, which has low cost, novel scheme and unique configuration. , the principle is novel, the flexibility is high, the debugging time is short, and the electronic devices can be assembled repeatedly on site, which can meet the actual needs of children's educational training, fill the gaps in related technologies, and produce greater social and economic benefits.
