Abstract

The utility model discloses an observer for observing spark plug flashover situations with variety types. The utility model comprises a shell body and a high-pressure modular circuit, wherein, the shell body is provided with more than one spark plug mounting and testing hole and a power switch. The utility model directly observes the spark plug flashover situations with variety types, provides help for consumers to buy products, and also provides a new method for manufacturers to sell products.

Description

A kind of spark plug sparking scope

The utility model relates to a kind of scope that is used for comparison different model spark plug sparking performance.

At present, the producer of domestic production spark, to its product arcing performance test all is to carry out at workshop, the product that only meets testing standard just can dispatch from the factory and enter the selling market, when the consumer buys product, can only come the arcing performance of comparison different model kind spark plug by the character introduction material that producer provides, in addition, have nothing for it.

The purpose of this utility model provide a kind of can Direct observation the scope of contrast different model, kind spark plug sparking performance.

The technical solution of the utility model is: a kind of spark plug sparking scope, this scope is made up of housing and the high-pressure modular circuit that is positioned at enclosure interior, on the output circuit of high-pressure modular circuit, be connected in series a cold cathode heavy-current discharge pipe FD, on housing, had one or more spark plug installation testing hole.

Above-mentioned high-pressure modular circuit is by direct supply E, resistance R, triode G, the main coil L of transformer ₁, L ₂The input circuit of forming and by the secondary coil L of diode D, capacitor C, transformer ₃The output circuit of forming constitutes.

Be serially connected with voice integrated package A and loudspeaker B on the above-mentioned high-pressure modular input circuit.

The utility model has following advantage:

1, can Direct observation compare different model spark plug sparking situation, offer help, also provide a kind of new mode for producer's sell goods for the consumer buys product.

2, when the consumer observes the spark plug sparking situation, can hear the introduction of announcer by the loudspeaker B that is located on the scope to these properties of product characteristics, for buying product, the consumer provides convenience.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model structural representation;

Fig. 2 is the high-pressure modular circuit diagram.

Structure of the present utility model as shown in Figure 1, form by housing 1 and the high-pressure modular circuit that is positioned at housing 1, have one or more spark plug installation testing hole 2 at the top of housing 1, power switch 3, loudspeaker B, be provided with kitchen cabinet 5 at the middle part of housing 1, be used for putting the product of different model, the high-pressure modular circuit as shown in Figure 2, by direct supply E (voltage is 4.5V-6V), resistance R, triode G, the main coil L of transformer ₁, L ₂The input circuit of forming and by the secondary coil L of diode D, capacitor C, transformer ₃The output circuit of forming constitutes.String has voice integrated package A (IC9003 One Time Programmable speech chip) and loudspeaker B on input circuit, has been connected in series a cold cathode heavy-current discharge pipe FD on output circuit.As can be seen from Figure 2, it is basic identical with common high-pressure modular, difference at first is to have gone here and there a high voltage device FD on output circuit, it is a kind of cold cathode heavy-current discharge pipe, after connecting modular power source, output terminal 1, obtain the high pressure of tens thousand of volts on 3, make the comb electrode of encapsulation in the FD straight tube produce corona discharge, gas is ionized state in the pipe, and moment conducting, be stored on the high-voltage capacitance C energy promptly by discharge tube by 2,3 ends discharge to the load spark plug, when voltage on the capacitor C is reduced to 2000V when following because of discharge, cold cathode heavy-current discharge pipe FD recovers cut-off state again, voltage charges to tens thousand of volts and discharge once more again on the capacitor C ... move in circles, even output terminal is short-circuit condition, also can constantly produce the heavy current high-voltage pulse, next is to have set up voice integrated package A (IC9003 One Time Programmable speech chip) in this circuit, after turning on the power switch, when watching the spark plug sparking situation, can listen the introduction of announcer by loudspeaker B, provide convenience for the consumer buys product to these properties of product characteristics.

Using method of the present utility model:

Spark plug is inserted in the spark plug instrument connection 2 on the scope, energized can be observed the arcing situation of spark plug, if the spark plug of two kinds of different cultivars is inserted in two instrument connections, energized, get final product the arcing situation of two kinds of spark plugs of paired observation, provide foundation for the consumer buys product.
