The utility model has the advantages that: do not need during the use need open / close the switch with present product that kind, adopt wireless charging, no connecting wire does not need the plug socket, and is very convenient, use solar energy to provide the electric energy environmental protection and energy saving of charging.
Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of wireless charging induction type dust absorption blackboard eraser.
Background technology
The primary structure of prior art comprises shell, hairbrush bar and axial flow electric fan, hairbrush bar is located at the front side of shell, and axial flow electric fan is housed in the enclosure, is provided with dust inlet hole in the front side of shell, shell below or side be provided with steam vent, be provided with dust collection storehouse and battery at shell.The shortcoming existed is: need off/on switches during use, inconvenient; Need to change battery or to be electrically connected with city with power line to charge, also inconvenience; Not there is the function using solar energy to provide charging, do not meet the modern concepts of energy-conserving and environment-protective.
Summary of the invention
The utility model object is to provide a kind of wireless charging induction type dust absorption blackboard eraser, to solve the use inconvenience that prior art exists, and does not have the problem using solar energy to provide the function of charging.
The technical solution of the utility model is: a kind of wireless charging induction type dust absorption blackboard eraser, comprise shell, hairbrush bar and axial flow electric fan, hairbrush bar is located at the front side of shell, axial flow electric fan is housed in the enclosure, be provided with dust inlet hole in the front side of shell, shell below or side be provided with steam vent, be provided with dust collection storehouse and battery in the enclosure, it is characterized in that, be respectively equipped with infrared distance sensor and human inductor in the front side of described shell and lateral inner; Described battery is rechargeable battery, wireless charging receiver and controller is provided with in this shell, the output of this wireless charging receiver is connected with this rechargeable battery, described infrared distance sensor, the output of human inductor connect from the different input interfaces of controller respectively, and the output of controller is connected with axial flow electric fan.
Described shell is mutually fastened by shell front side and shell bonnet and forms, and is provided with independently dust collection Cang Gai in one end of this shell bonnet, and the inner side of this dust collection Cang Gai is described dust collection storehouse.
Described controller adopts ultra low-power microcontroller control circuit.
Described rechargeable battery adopts lithium battery.
The utility model has the advantages that: easy to use, do not need to need off/on switches like that with present product during use, as long as with hand-held blackboard eraser, the automatic sensor circuit of human body will be connected, but not dust suction; When erasing the board, near blackboard in a flash, infrared distance measuring circuit working, dust collecting electric fan operates blackboard eraser, starts dust suction, postpones half second and stop dust suction after wiping blackboard.Blackboard eraser is placed directly on wireless charging electroplax, carries out wireless charging, without connecting line, does not need to plug socket, very convenient; Use solar energy to provide rechargeable electrical energy environmental protection and energy saving, student, in the process using said apparatus, not only avoid the harm of dust, and can the knowledge of learning physics automation in practice, improves the quality of teaching.
