Abstract
The invention particularly provides a warming-supportive blackboard eraser with an LED lamp. The warming-supportive blackboard eraser comprises a board seat and a board eraser body. The warming-supportive blackboard eraser is characterized in that the board eraser body is fixed on the board seat, a hollow cavity is arranged in the board seat, a far infrared warming device is arranged in the hollow cavity, and the LED lamp is arranged on the board seat and connected with a storage battery arranged on the board seat through a switch controlling the LED lamp. The warming-supportive blackboard eraser has the advantages that compared with the prior art, functions of existing blackboards are expanded, and the LED lamp is additionally arranged, so that a teacher is facilitated to wipe a blackboard clean in darkness. In addition, the far infrared warming device is arranged, so that cold freezing of the teacher when wiping the blackboard in winter can be avoided; a micro-nano power far infrared coating layer converts absorbed heat into far infrared electromagnetic waves for radiation, and far infrared rays after being absorbed by human bodies can activate cells and improve immunity of people, so that the warming-supportive blackboard eraser has good healthcare effect.
Description
Technical field
The present invention is specifically related to a kind of heating blackboard eraser with LED.
Background technology
Blackboard eraser is the necessary article of classroom instruction, but existing blackboard eraser function is more single, can not meet the teaching request of teacher.Such as, under rather dark condition, the letter written with chalk on blackboard is not easy to be easily wiped clean.In addition, at arctic weather in winter, teacher's both hands are exposed when erasing the board with blackboard eraser outside, and hand can feel cold, and traditional blackboard eraser does not have the function of warm hand.
Summary of the invention
The object of the invention is to overcome blackboard eraser function in prior art more single, not there is the defect of heating and illumination functions.
For this reason, the invention provides a kind of heating blackboard eraser with LED, comprise panel seat and blackboard eraser, described blackboard eraser is fixed on panel seat, is provided with a hollow cavity in panel seat, is provided with far-infrared heating and arranges in hollow cavity; Panel seat is provided with LED, and described LED is connected with the battery be arranged on panel seat by the switch controlling it.
Described far-infrared heating device comprises the fin being arranged on hollow cavity inwall surrounding, is provided with heating equipment in the space that fin surrounds.
The outer surface of described fin is coated with micro-nano ground rice far ultrared paint layer, and described heating equipment is the electric heating sheets be made up of ferrum-chromium-aluminum.
Described panel seat sidepiece is provided with a temperature detect switch (TDS), and described heating equipment is connected with battery by temperature detect switch (TDS).
The top in described panel seat front is provided with a groove coordinated with LED size, and described LED is embedded in groove, is coated with Transparent lamp shade above groove.
Described panel seat top is provided with a battery compartment, and battery is arranged in battery compartment, controls the switch-linear hybrid of LED at panel seat sidepiece.
Beneficial effect of the present invention: compared with prior art, the present invention has expanded the function of existing blackboard eraser, has set up LED, is conducive to teacher and wipes clean blackboard under rather dark condition.In addition, be provided with far-infrared heating device, teacher not only can be avoided to occur when winter erases the board freezing hand phenomenon, and micro-nano ground rice far ultrared paint layer carries out radiation the form that the converting heat absorbed is far infrared electromagnetic, after far infrared is absorbed by the body, can activating cell, strengthen the immunity of people, there is good health-care efficacy.Structure of the present invention is simple, reasonable in design, not only easy to use, and is of value to healthy.
Below with reference to accompanying drawing, the present invention is described in further details.

Detailed description of the invention
Embodiment one:
More single for overcoming blackboard eraser function in prior art, not there is the defect of heating and illumination functions, the invention provides a kind of heating blackboard eraser with LED, as illustrated in fig. 1 and 2, comprise panel seat 1 and blackboard eraser 12, described blackboard eraser 12 is fixed on panel seat 1, a hollow cavity 11 is provided with in panel seat 1, be provided with far-infrared heating in hollow cavity 11 to arrange, heat can be given out rapidly, make blackboard eraser 12 keep uniform temperature, give out the far infrared being of value to health-care effect simultaneously, can activating cell, stimulate circulation.
Panel seat 1 is provided with LED 3, the top in described panel seat 1 front is provided with a groove 2 coordinated with LED 3 size, described LED 3 is embedded in groove 2, groove 2 is coated with Transparent lamp shade above, described LED 3 is connected with the battery 7 be arranged on panel seat 1 by the switch 5 controlling it, under rather dark condition, facilitate teacher to wipe clean blackboard.
Embodiment two:
As described in embodiment one, far-infrared heating device comprises the fin being arranged on hollow cavity 11 inwall surrounding, heating equipment 10 is provided with in the space that fin 8 surrounds, the outer surface of described fin 8 is coated with micro-nano ground rice far ultrared paint layer 9, far infrared magnetic field can be produced immediately after energising, improve heat dissipation capacity, produce health-care effect to the human body in Far infrared magnetic field range of effective radiation, this coating has good absorptivity simultaneously, decrease thermal loss, there is energy-conservation object.In order to reach the fast object of programming rate, described heating equipment 10 is the electric heating sheets be made up of ferrum-chromium-aluminum, described panel seat 1 sidepiece is provided with a temperature detect switch (TDS) 4, and described heating equipment 10 is connected with battery 7 by temperature detect switch (TDS) 4, can be regulated the temperature of applicable hand by temperature detect switch (TDS) 4.
For the ease of changing battery 7, described panel seat 1 top is provided with a battery compartment 6, and battery 7 is arranged in battery compartment 6, and the switch 5 controlling LED 3 is arranged on panel seat 1 sidepiece.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
