Abstract

The utility model relates to an electric heating art designing pen which is suitable for writing of hard pen Chineseink rubbing calligraphy and hot stamping of electrical aluminium on the surface of paper, plastic, leather, etc. The front bracket section of a heating head is provided with a ring-shaped groove, and both sides of a back bracket of the heating head are cut to decrease contact areas between the both sides and a pen head. The front end of the heating head is provided with a small column or a small screw connected with a movable writing head, and the existing circuit only uses one transistor, which simplifies the circuit. The front end of the pen head corresponding to the section of a temperature control circuit is provided with two circular holes, namely a display hole which displays the work situation of the circuit and a temperature regulating hole which regulates an adjustable resistor to change the work points of the heating head. Volume is reduced by using high quality rechargeable batteries and manganese copper wires as heating wires.

Description

Electrothermal art designing pen

The utility model relates to a kind of electrothermal art designing pen, is applicable to that hard-tipped pen open up black calligraphy and write, and also is adapted to the thermoprint of the electrochemical aluminium film of shades of colour word on paper, plastics and the leather surface or pattern.

The patent No. be ZL's 93204622.3 " portable pocket gold stamping pen " in processing is used, have following defective:

1, owing to adopt No. 5 batteries of common two joints, makes the size of pen not too big again, bring difficulty, and cooperate between heating and the nib and more closely cause thermal loss bigger process, wind the line, assemble, be subjected to the force intensity aspects; 2, a kind of nib is difficult to adapt to the various needs of writing, scribbling; 3, circuit is complicated; 4, need open the operating temperature that nib could be regulated the heating head, very inconvenient.

In order to overcome above-mentioned shortcoming, the utility model provides a kind of minimizing thermal loss, can change nib, circuit is simple, temperature adjustment electrothermal art designing pen easily.

Task of the present utility model is finished like this:

The groove of an annular is set at a heating fore-stock place, a heating after-poppet both sides excision is inverted T-shape to reduce they and written contact area, transmit and reduce thermal loss thereby reduce heat, forward support periphery and the remaining circumferential section of after-poppet have kept the heating head to be fixed in stability on the nib simultaneously; The small column or the Screw of a connection activity pencil are set at the front end of heating head, be used for changing different pencils according to different purposes, can write, draw different sizes, thickness and difform curve, being particularly suitable for hard-tipped pen opens up black calligraphy and writes, and write simple, with to use pen, ball pen the same, be hard-tipped pen calligraphical works fan's ideal tools; To be the bridge-type temperature control circuit with secondary amplify primary circuit carries out temperature control, and existing circuit is only used a transistor, has simplified circuit, and it is about 40% that volume has reduced, easy to use, reduced cost; The shape of circuit board is arranged to consistent with written hole taper, to make full use of the space in the nib, prevents that pen is long, makes easy to carry; The front end of corresponding temperature control circuit place nib is opened two circular holes, and one is to show the hole, the display circuit working condition, and one is the temperature adjustment hole, regulates adjustable resistance to change the operating point of the head that generates heat; Select for use high-quality rechargeable battery and manganese-copper filament to make heating wire, reduced volume, and coiling is convenient, do not cause a heating temperature to reduce when the working time is longer.

Fig. 1 is the longitudinal section of the utility model head, Fig. 2 is the longitudinal section of movable pencil embodiment, and Fig. 3 is the temperature control circuit schematic diagram of heating head, and Fig. 4 is the perspective view of heating head from caudal directions, Fig. 5 is a vertical secondary view of the present utility model, and Fig. 6 is an outline drawing of the present utility model.

In conjunction with the accompanying drawings structure of the present utility model and embodiment are described as follows:

The utility model is made up of the pen cap 14, battery 17, temperature control plate 13, thermistor 12, nib 1, heating 2 and pencil 4.It is characterized in that, the front end of heating 2 is provided with annular groove 3, the back adds 9 both sides and is inverted T-shape, fore-stock 16 outer circumference surfaces of heating 2 and two arc surfaces of after-poppet 9 and the interior circular hole of written 1 front end are tight fit, in the middle of the cylinder of heating head back a cannelure 21 is set, in thermistor 12 embedded grooves 21, movable pencil 4 is connected on the small column 10 of heating head, cone-plate inserts in the written taper hole before the temperature control plate 13, the interior circular hole of back plate two sides and written rear end is tight fit, heating wire 15 is on the cylinder of 16 of heating an after-poppet 9 and fore-stocks, rechargeable battery 17 is arranged on the rear portion in the pen cap 14, show light emitting diode 20 on the corresponding temperature control plate in position in hole 7 on the nib 1, i.e. BG2 on the temperature control plate, the corresponding adjustable resistance 18 in the position in temperature adjustment hole 8 is the R2 on the temperature control plate, on the end housing K switch is set before the pen cap, the outside diameter of heating head only is the 2.5-3 millimeter, long 12-13 millimeter, and weight only is the 0.15-0.2 gram; Temperature control circuit is made up of thermistor R1, temperature adjustment resistance R 2, resistance R 3, transistor BG1, heating wire R4, light emitting diode BG2, resistance R 5, battery U, K switch.

The K that closes a switch, powered battery, R1, R2, R3 provide the initial start operating point for transistor BG1, circuit start, temperature raises, and thermistor R1 resistance increases, transistor BG1 operating current reduces, and the electric current of heating wire R4 reduces, when the temperature of heating head reduces, resistance R 1 resistance reduces to make the BG1 electric current to increase, the electric current of R4 also increases, and the temperature of heating head raises, and has reached the effect of constant temperature economize on electricity, regulate the resistance of R2, thereby can change the temperature spot that the operating point changes the heating head.

Through experiment, the utility model has the advantages that:

1, owing to reduced thermal loss, the heating-up time of fever head was by original 40 seconds-1 minute Add near 30-40 about second, the maintenance work electric current is 220-250mA; 2, do with No. 5 rechargeable batteries Power supply, stream time can be kept about 2 hours; 3, the Mobile books writing head is replaceable is among Fig. 2 5,6 etc., enlarged the scope of application; 4, can according to anodized aluminium and the working environment of different model The temperature of regulation heating head easily.
