Description
Technical field
The utility model is specifically related to a kind of warm blackboard eraser with LED lamp.
Background technology
Blackboard eraser is the necessary article of classroom instruction, and still, existing blackboard eraser function is more single, can not meet teacher's teaching requirement.For example, under rather dark condition, the letter written with chalk on blackboard is not easy to be wiped clean.In addition, at arctic weather in winter, teacher's both hands are exposed while erasing the board with blackboard eraser outside, and hand can feel cold, and traditional blackboard eraser does not have the function of warm hand.
Utility model content
The purpose of this utility model is that to overcome in prior art blackboard eraser function more single, does not have the defect of heating and illumination functions.
For this reason, the utility model provides a kind of warm blackboard eraser with LED lamp, comprises panel seat and blackboard eraser, and described blackboard eraser is fixed on panel seat, is provided with a hollow cavity in panel seat, is provided with far-infrared heating device in hollow cavity; Panel seat is provided with LED lamp, and described LED lamp is connected with the battery being arranged on panel seat by the switch of controlling it.
Described far-infrared heating device comprises the fin that is arranged on hollow cavity inwall surrounding, in the space that fin surrounds, is provided with heating equipment.
On the outer surface of described fin, be coated with micro-nano ground rice far ultrared paint layer, described heating equipment is the electric heating sheets of being made by 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 coordinating with LED lamp size, and described LED lamp 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, and the switch of controlling LED lamp is arranged on panel seat sidepiece.
The beneficial effects of the utility model: compared with prior art, the utility model has been expanded the function of existing blackboard eraser, has set up LED lamp, are conducive to teacher and wipe clean blackboard under rather dark conditions.In addition, be provided with far-infrared heating device, not only can avoid teacher when erase the board winter, to occur freezing hand phenomenon, and the form that micro-nano ground rice far ultrared paint layer is converted into far infrared electromagnetic the heat absorbing is carried out radiation, after far infrared is absorbed by the body, can activating cell, strengthen people's immunity, there is good health-care efficacy.The utility model is simple in structure, reasonable in design, not only easy to use, and is of value to healthy.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional view of the present utility model.
Description of reference numerals: 1, panel seat; 2, groove; 3, LED lamp; 4, temperature detect switch (TDS); 5, switch; 6, battery compartment; 7, battery; 8, fin; 9, micro-nano ground rice far ultrared paint layer; 10, heating equipment; 11, hollow cavity; 12, blackboard eraser.
The specific embodiment
Embodiment 1:
More single for overcoming in prior art blackboard eraser function, the defect without heating and illumination functions, the utility model provides a kind of warm blackboard eraser with LED lamp, 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, in panel seat 1, be provided with a hollow cavity 11, in hollow cavity 11, be provided with far-infrared heating device, can give out rapidly heat, make blackboard eraser 12 keep uniform temperatures, give out the far infrared that is of value to health-care effect simultaneously, can activating cell, stimulate circulation.
Panel seat 1 is provided with LED lamp 3, the top in described panel seat 1 front is provided with a groove 2 coordinating with LED lamp 3 sizes, described LED lamp 3 is embedded in groove 2, groove 2 is coated with Transparent lamp shade above, described LED lamp 3 is connected with the battery 7 being arranged on panel seat 1 by the switch 5 of controlling it, under rather dark condition, facilitates teacher to wipe clean blackboard.
Embodiment 2:
As described in embodiment mono-, far-infrared heating device comprises the fin that is arranged on hollow cavity 11 inwall surroundings, in the space that fin 8 surrounds, be provided with heating equipment 10, on the inner surface of described fin 8, be coated with micro-nano ground rice far ultrared paint layer 9, after energising, can produce immediately far infrared magnetic field, improve heat dissipation capacity, the human body in Far infrared magnetic field range of effective radiation is produced to health-care effect simultaneously, this coating has good absorptivity, reduce thermal loss, there is energy-conservation object.In order to reach the fast object of programming rate, described heating equipment 10 is electric heating sheets of being made by 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, by temperature detect switch (TDS) 4, can regulate the temperature that is applicable to hand.
For the ease of changing battery 7, at described panel seat 1 top, be provided with a battery compartment 6, battery 7 is arranged in battery compartment 6, and the switch 5 of controlling LED lamp 3 is arranged on panel seat 1 sidepiece.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection scope of the present invention.
