The present invention relates to a cigarette lighter with a built-in battery checker (hereinafter abbreviated as a battery checker / cigarette lighter), and more particularly, one or two indicator lights on a cigarette lighter for a car. The battery checker and cigarette can be used both for the purpose of saponification to cigarettes and for the purpose of visually discriminating the consumption of the battery from the change in the intensity or color of the light. It's about a lighter.

A car is usually equipped with a cigarette lighter, which is operated by batteries installed in the car.

However, the battery is not only a cigarette lighter but also a power source for auto starters, before ignition, outdoor lights, indoor lights, radios, and the like.If the consumption exceeds a predetermined value, the vehicle cannot be started and the battery is replaced or charged. You have to do a lot of troublesome work, etc. However, the consumption of the battery is not known if the voltage is measured with a precision voltmeter, but can not be easily determined by measuring the voltage with a conventional voltmeter. As a countermeasure, it is possible to equip a battery checker, but since the cost becomes high and a space is required separately, it is difficult to put it into practical use for these reasons. Therefore, in the automobile industry, there has been a great demand for the development of a battery checker that can be equipped with a simple structure without requiring a separate space on the front or side dashboard of the driver's seat.

Accordingly, one object of the present invention is to provide a battery checker cigarette lighter for automobiles.

It is another object of the present invention to provide a battery checker / cigarette lighter that combines both functions of a cigarette lighter and a battery checker as a single auto part that can be purchased in an interior of a vehicle, for example, a front panel of a driver's seat.

Another object of the present invention is to provide a conventional cigarette lighter for automobiles equipped with a small battery checker in an internal office that can visually determine the consumption of batteries.

Another object of the present invention is an automobile cigarette lighter having a lighting knob having one or two indicator lamps in the interior of the vehicle, which, when pressed to heat the lighter, simultaneously indicate the consumption of batteries installed in the vehicle by means of a roughness car. To provide a lighter.

Another object of the present invention is to remove the battery checker cigarette lighter that can check the consumption of the battery even during the day by comparing the color of the change light generating means with the light of the reference light generating means.

Other objects, advantages and features of the present invention will be described in more detail below.

The present invention combines the function of a battery checker with a conventional cigarette lighter for automobiles in order to meet the above-mentioned demands. According to the present invention, a movable material provided with a heater at the front end of a press body in a reciprocating direction in a reciprocating direction It consists of two parts, the heater part attached to the body part and the gas part which accommodated this heater part as detachable material, and the said heater contact | connects an electrode plate by the pressure of the said press body, and it heats by electricity from a battery, In the configuration in which the heater unit is ejected from the base unit, change light generating means for reducing the brightness of the heater unit in accordance with the consumption of the battery inside the pressing body, and reference light generating means for comparing with light emission of the change light generating means. Cigarette lighter for automobile built-in checker, characterized in that the provision is provided.

This invention will be described in more detail based on the accompanying drawings below.

In FIG. 1, the heater part I equipped with the battery checker is normally embedded in the front panel or side panel close to the driver's seat, and is detachably inserted into the base unit II. The heater portion I is generally cylindrical, and in some cases, a polygonal or ordinary shape having a quadrilateral shape or a hexagonal shape may be used. The base portion II is formed according to the shape of the heater portion inserted therein. .

In this base portion II, the holder 41 is generally cylindrical and made of a conductive material such as a copper alloy.

One end of the holder 41 is open for insertion of the heater part I, while the other end is closed so that there is a perforation to form a hole, through which electrical means for connecting the electrode and the battery are provided. Lost

In the holder 41, the electrode plate 43 sandwiched by the ceramic plate 42 and the insulating plate 46 protrudes outward through the hole, and thus the bolt 44 serving as an electrode and the nut 45 engaged therewith. It is fixed to the holder 41 by the (). The conductive wire from the battery E is connected to the bolt 44 and the holder 41.

The heater part I is shown in detail in FIG. When the cigarette lighter is not used, the heater plate 7 and the heater 8 are positioned slightly away from the electrode plate 43 as indicated by the dotted line.

In Fig. 2, the holder 1 is usually made of a conductive material in a cylindrical shape, and an annular ring 2 is formed at an arbitrary position, i.e., an inner circumferential surface. The front end of the holder 1 is opened and the rear end part is bent outward to form the jaw portion 3.

The case 4 is usually cylindrical and made of a conductive material, and the tip is closed by a stopper and case cover 5. The ceramic plate 6 is generally disk-shaped and has both insulation and heat resistance effects, and is interposed between the lid 5 and the conductive heater plate 7 accommodating the heater 8. One end of the heater 8 is connected to the heater dish 7 at the connection point 9 and the other end is connected to the connection point 11 of the conductive bolt 10. The heater plate 7, the heater 8, and the like are attached to the tip of the case 4 by means of the long nut 12 and the bolt 10, for example, by screwing or the like.

Further, (13), (14), (15) and (16) are mica plates, respectively, between the heater 8 and the heater plate 7 and between the heater plate 7 and the ceramic plate 6, respectively. Insulation between the heater plate and the case is ensured by interposing between the ceramic plate 6 and the lid 5 and between the lid 5 and the long nut 12.

In addition, the rear end of the case 4 is insulated by the mica plates 20 and 21 interposed between the spring stopper 17 and the pressing body 18 so that the long bolt 19 and the long nut 12 are provided. Is fixed by).

The press body 18 is formed of a material such as heat-resistant plastic, and a recess 22 is provided at a rear end thereof, and the inner part of the press body 18 is a partition plate 23 provided with a slit 23 'as needed. In each chamber, indicator lamps 24 and 25 are received and removed by translucent lids 26. Reference numeral 27 denotes a wire connecting the heater plate 7 and the indicator light 25, 28 a conductor wire connecting the case 4 and the indicator light 24, 29 an indicator light 25 ) And a conductive line connecting the conductive wire 28, 32 is a conductive wire connecting the indicator light 24 and the long bolt (19).

In one embodiment of the present invention, these indicators are white arc lamps, and in other forms, are combinations with one or two colored arc lamps or white arc lamps.

The movable body 31 is comprised as each part represented by the code | symbols (4)-(30) mentioned above. A spring, for example, a spiral spring, is interposed between the spring stopper 17 of the movable body 31 and the convex (2 ring in the inner circumferential surface) 2 of the holder 1 and is fixed at either end or both ends. Therefore, when the holder 1 is fixed and the movable body 31 is pressed against the tension of the spring 32, the movable body 31 slides forward, and when the pressure is released, the movable body 31 is spring ( By the tension of 32).

When operating the battery checker / cigarette lighter of the present invention, when the pressing body 18 is pressed first, the movable body 31 moves forward, and the heater dish 7 contacts the electrode plate 43. At this time, the heater 8 is heated by the current from the battery, and the indicator 24 as a change light generating means in series with the heater 8 is turned on, and at the same time, the heater 8 and the series of indicators 24 are turned on. The indicator 25 as the reference light generating means in parallel also lights up. In this case, if the battery E is not consumed for the reasons described later, both indicator lights 24 and 25 are turned on at approximately equal brightness. However, if the battery E is consumed more than specified, the indicator 24 lights up darker than the reference light indicator 25, so that the brightness (light intensity) of the change light generating means is changed to the indicator 25 of the reference light generating means. By comparing the brightness of), the fact that the battery (E) is consumed is visually proved.

Once the heater 8 is heated, it is conventional to pull the press body 18 to separate the heater plate 7 from the electrode 43 and to simultaneously remove the heater part I from the gas part II and to light a cigarette. Same as the cigarette lighter. If necessary, the cigarette lighter and battery checker of the present invention automatically pops up when the heater 8 is sufficiently heated, shuts down the electric circuit, and at the same time, excess current flows by returning the pressurized movable body 31 to its original position. It goes without saying that a conventional automatic pull back device (not shown) may be provided to prevent the heater 8 from overheating.

3A, 3B, and 4 show an electric circuit of one type of battery checker according to the present invention, and the symbols have the same meanings as those of FIGS. 1 and 2.

3a and 3b show an embodiment of the electric circuit of the battery checker of the present invention showing the relationship between the illumination difference of the indicator lights 24 and 25 and the consumption degree of the battery E. As shown in FIG.

In FIG. 3A showing the case of using a new battery or a fully charged battery, a large current is used for the indicator light 24 and a small current is used for the indicator light 25 so that the battery E maintains the rated voltage. In this case, when not being consumed, both indicators 24 and 25 are selected or adjusted in advance so as to have the same brightness.

In FIG. 3B, which shows the case of using a battery that is considerably consumed, "r" represents the internal resistance of this battery. In this case, the value of "r" becomes extremely large and cannot be ignored, so that the equivalent circuit of the indicator 24 is greatly affected. Even in this state, the indicator lamp 25 is originally large in resistance, so there is no change in brightness, but the indicator lamp 24 is greatly affected because of the low resistance.

Therefore, the indicator 24 can visually prove that the brightness E is greatly reduced compared to the indicator 25 and the battery E is consumed. If the slits 23 'are present, the discrimination becomes clearer.

4 is a circuit diagram showing another embodiment of the battery checker according to the present invention, in which the indicator lamp 24 for high current is connected in series with the resistor 8 'without connecting the heater 8 in series, where the battery E ). In this example, in order to light a cigarette, a large current is distributed to the heater 8, and the indicators 24 and 25 are also turned on, and are completely the same as described in FIGS. 3A and 3B. Since the brightness of the indicator light 24 is extremely reduced when the consumption of the light proceeds, the fact that the battery is immediately consumed can be recognized by comparing the brightness of the indicator light 24 with the brightness of the indicator light 25.

3A, 3B, and 4, the brightness of the high current indicator light 24 and the small current indicator light 25 is the rated voltage at which the battery E is not consumed. Although it is made equal, this may be lighter than the indicator light 25 side. That is, in this case, the consumption of the battery is visually shown in such a shape that the brightness of the indicator 24 is equal to the brightness of the indicator 25.

In FIG. 5 showing another embodiment of the present invention, the recessed part 22 is deeply colored with a high current indicator, for example, a blue indicator 24B and a small current indicator. One, for example, is used to check the consumption of the battery E with the red indicator light 25R. Other symbols in FIG. 5 have the same meanings as those shown in FIG. In this example, when the battery is sufficiently charged, the brightnesses of the indicators 24B and 25R are selected or adjusted to be the same.

While the output of the battery is maintained at the rated value, the semi-transparent plate 26 is brightly colored yellow by adding color on both sides. If the battery is somewhat consumed, the brightness of the indicator light 25R as the reference light generating means remains the same and the brightness of the indicator light 24B as the changing light generating means decreases, so that the translucent plate 26 changes from yellow to orange. . When the battery is further consumed, the light is emitted from orange to red, so it is easy to determine whether or not the battery is consumed.

It is also possible to find out the consumption of the battery in the color of the mixed liquid on the pressure knob surface of the cigarette lighter / battery checker of the present invention. In this example, discrimination is made by changing the color, which is different from the comparison of the brightnesses shown in FIGS. 2, 3a, and 3b.

In this embodiment, the indicator 24B acts as the change light generating means, and the indicator 25R acts as the reference light generating means for imparting a constant generation.

FIG. 6 shows a variation of the embodiment shown in FIG. 5, in which the combination of the white light 25W and the red transparent plate 26R is used as the reference color developing means to change the color of the blue light 24B. Compare with generating means. Since the red illumination of the transparent plate is falsely colored with the blue illumination of the indicator 24B, the same effect as in the example shown in FIG. 5 is obtained. The consumption degree of the battery E can be determined by the same method as described with respect to the example of FIG.

FIG. 7 shows another variant of the example of FIG. 5 wherein the battery checker is of a more simplified structure, i.e. using only a red transparent plate 26R to generate a reference color and a blue indicator light. 24B is used as the change color generating means. In this example, even if the change light of the indicator 24B is reduced, the red transparent plate 26R appears red by the light from the outside. Therefore, the consumption of the battery can be determined by the color illumination on the transparent plate 26 in the same manner as the method shown in the example shown in FIG.

In this modification, the combination of the red transparent plate 26R and the white light for small current may be used as the reference color generating means.

In addition, in the form shown in FIGS. 5-7, the color and lightness of an indicator may be selected suitably, and it may facilitate determination of the change in color illumination. For example, the consumption of the battery may be determined by using a combination of a blue transparent plate and a white indicator as a reference color generating means and a red indicator as a change color generating means.

The cigarette lighter / battery checker according to the present invention has a simple battery checker that is a simple structure built into the pressure knob of the conventional car cigarette lighter without requiring any extra space in the front panel of the driver's seat. Of course, it is particularly advantageous because it can be used simply and at the same time as igniting with a cigarette lighter. In addition, it is also advantageous that the consumption of the battery can be easily detected visually by comparing the brightness of the change light generating means with that of the reference light generating means. In addition, in the case where the color illuminating means is used for both the change light generating means and the reference light generating means, the difference in the brightness in both means is represented by the color difference, so there is an advantage that the detection of the consumption of the battery is possible even in bright day.

It should be apparent to those skilled in the art that various forms of the invention shown and described herein are merely illustrative, and that various modifications may be made without departing from the spirit of the present invention and the scope of subsequent claims. Will be one day.
