Description

Automatically respond to electric candle

[technical field]

The utility model relates to a kind of electron emitting structure.

[background technology]

In the daily life, various electronic acoustooptic devices are widely used in toy, home decoration articles for use, the gift.For example, people be originally candle as a kind of lighting, but along with the generally use of electric light source, its illumination functions is desalinated gradually, people also transfer sight or temperament and interest to by practicality to the demand of candle, so electronic flash candle, musical candle etc. have just occurred.This class candle comprises housing, control circuit, illuminating part and music circuit etc., switch open, and the luminous form of control circuit control luminous component simulation candle, or realize functions such as light-emitting flash, broadcast music.

[summary of the invention]

Main purpose of the present utility model is: provide a kind of control to respond to electric candle easily automatically.

For achieving the above object, the utility model proposes a kind of automatic induction electric candle, comprise shell, soft-touch control and illuminating part; Described soft-touch control is installed in the described shell, is electrically connected with described illuminating part; Described soft-touch control comprises the touch utmost point and control circuit, and the described touch utmost point is located in the described shell, is electrically connected with described control circuit.

Above-mentioned automatic induction electric candle, described touch is sheet or wire very, along the inner wall surrounding setting of described shell.Described touch is cylindrical shape or circular ring metal thin slice very.

Above-mentioned automatic induction electric candle also comprises box body, is located in the described shell; Described control circuit is located in the box body, and the described touch utmost point is arranged at the outer surface of described box body, between described shell and box body.Described touch is cylindrical shape or circular ring metal thin slice very, is located on the outer wall of described box body.

Above-mentioned automatic induction electric candle also comprises the flame housing, is modeled to flame profile, covers at outside the described illuminating part.

Above-mentioned automatic induction electric candle, described shell is H shape along longitudinal axis cross section, forms upper chamber and lower cavity, and described illuminating part is positioned at described upper chamber bottom; Described soft-touch control is positioned at described lower cavity.

Above-mentioned automatic induction electric candle, described shell is cylindric, it is H shape along the cross section, axle center, forms upper chamber and lower cavity; Described touch is cylindrical shape or annular very, is arranged in the described shell with described shell is coaxial.

Or above-mentioned automatic induction electric candle, described shell is a cup.

Or above-mentioned automatic induction electric candle, described shell is the cup of back-off, comprises sidewall and roof, its roof offers through hole; Described illuminating part is arranged at roof top, and is electrically connected with described movement by this through hole.

Owing to adopted above scheme, the utility model is by the contact of staff, detects the variation of impedance by control circuit, just can directly realize in view of the above opening and shutoff, and is very easy to use.And improved the interest of this series products thus greatly.

Be different from the direct contact structures of staff that soft-touch control adopts in the prior art, in the wood utility model, the touch of soft-touch control is extremely hidden and is arranged in the shell, can not produce any adverse influence to the outward appearance of product, can't see the existence of switch in appearance, can guarantee to realize the function of switch again.

And, touch the utmost point and be designed to cylinder or when circular, be close to outer casing inner wall, when the user holds the utility model with habitual movement, the contact of formation larger area can make to touch significantly impedance variations of utmost point generation, guarantees the sensitivity to the signal detection of staff contact.

[specific embodiment]

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one:

Please refer to shown in Figure 1ly, be this routine cross section structure schematic diagram, comprise shell 1, movement 2, flame housing 3 and light-emitting component LED lamp 21; Movement 2 comprises box body 20, soft-touch control and LED lamp 21; Box body 20 is provided with battery case and hand switch; Shell 1 is made by wax or other transparent or semitransparent materials, such as, glass or PVC etc.; The outward appearance of shell 1 is cylindric, be " H " shape along its cross section, axle center, cavity of each tool of top and the bottom, movement 2 is installed in the bottom of shell 1, battery case and hand switch are positioned at the bottom, are convenient for changing battery, and its light-emitting component LED lamp 21 is located at the top, and the cavity bottom, top of stretching out shell 1, LED lamp 21 outer covers one are by the flame housing 3 of the wax flame that trnaslucent materials is made, likeness in form is burnt.Power supply is electrically connected with LED lamp 21 by soft-touch control, opens or turn-off LED lamp 21 by soft-touch control.

Also can built-in governor circuit in the movement 2, be used to control the supply current of LED lamp 21, make it flickering, simulation waxy luster flicker out, several looking genuine; Or control LED lamp 21 produces color change clocklike; Simultaneously, can also play music.

The touch utmost point 221 of soft-touch control adopts Copper Foil, becomes cylindric or annular, is attached at the outer surface of box body 20, is hidden in the shell 1, and is electrically connected with the circuit board 220 of laying contact switch control circuit by lead 222; Circuit board 220 is horizontally placed on the top of movement 2, and the pin of LED lamp 21 is inserted on the circuit board 220.

Please in conjunction with contact switch control circuit schematic diagram shown in Figure 2, because human body is a conductor, can regard a pole plate of electric capacity as, the touch utmost point Copper Foil on the circuit box 20 is another pole plate of electric capacity; When with hand near or hold product in a flash the time, the capacity of this electric capacity will increase, produce an impedance this moment, after detecting relatively by detecting circuit, send into control chip U2 inside again and carry out judgment processing, from control chip U2 output high level, make triode Q1 conducting at last, control chip U1 obtains exporting impulse wave after the low level, and LED lamp 21 is unlocked and lights.

When once more with hand near or moment of holding shell 1, the capacity of electric capacity will increase, produce an impedance, make the sensor vibrating circuit of control chip U2 inside produce a signal, after signal compares and enlarges through detecting circuit, signal is sent into control chip U2 inside again and is carried out judgment processing, control chip U2 exports high level, makes triode Q1 conducting, after control chip U1 obtains a low level, the output of stop pulse ripple, LED lamp 21 is closed.

Embodiment two:

Please refer to shown in Figure 3ly, the main difference part of this example and last example is that in this example, shell 1 is a glass, and movement 2 is loaded in the cup, pours into the space of wax 4 between wall of cup and movement again, forms an integral body.

Embodiment three:

Please refer to shown in Figure 4ly, the main difference part of this example and embodiment one is that this example and shell 1 are the cup of a back-off, and cup comprises sidewall and roof, and roof offers a circular hole; Movement 2 is packed into behind the cup, and LED lamp 21 protrudes in top wall surface by this circular hole just, and flame housing 3 covers at outside the LED lamp 21.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.For example, also can adopt other conductive material as the Copper Foil that touches the utmost point, such as iron plate, enamel-covered wire etc.
