Description

Prevent the electric mosquito flap of electric shock continuously

Technical field

The utility model relates to the instrument of a kind of manual seizure or kill insects, particularly a kind of electric mosquito flap of electric shock continuously that prevents.

Background technology

Chinese patent 94204760.5 and 95222858.0 disclosed two kinds of electric mosquito flaps comprise making body, electric shock net and high-voltage generator circuit, and high-voltage generator circuit is installed in the making body, and its high voltage source output is electrically connected with electric shock network source incoming end.Its shortcoming that mainly exists is when the contact wire side positive and negative electrode that human body is interrupted fast, be subject to the electric shock of quick interruption (electric shock is at interval less than 1 second), particularly children take mosquito to clap his man-hour that deliberately shocks by electricity, and the electric shock of this quick interruption can cause certain injury to people's spirit.

Invention constitutes

A kind of higher electric mosquito flap that prevents continuous electric shock of electric shock safety in utilization that can not be interrupted fast thereby being to overcome weak point of the prior art, the purpose of this utility model is provided.

The purpose of this utility model realizes by following approach:

Prevent the electric mosquito flap of electric shock continuously, comprise making body, electric shock net and high-voltage generator circuit, high-voltage generator circuit is installed in the making body, its high voltage source output is electrically connected with the electric shock net, its structural feature is: also comprise delay switch circuit and sample circuit, the time-delay control output end of delay switch circuit is connected with the control signal input of high-voltage generator circuit, and the signal output part of sample circuit then is electrically connected with the control input end of delay switch circuit.

Like this, sample circuit electric shock net or high-voltage generator circuit the signal of can taking a sample because of being produced by human body or insect bump, thereby trigger delay switch circuit and carry out deferred action, make high-voltage generator circuit in delay time, no longer produce high voltage source, solve effectively and be interrupted the problem of electric shock fast, improved the safety in utilization of electric mosquito flap human body generation injury.

Delay switch circuit can also further be specially;

Delay switch circuit can be a kind of transistor delay switch circuit, can also be a kind of relay delay switch circuit.

The transistor delay switch circuit is by delaying time with conducting according to transistorized, and the relay delay switch circuit is to delay time according to the electromagnetic action of relay, the two is prior art circuits, but in the utility model, realized time-delay in case electric mosquito flap carries out the effect of continuous discharge to human body, solve technical problem, reached technique effect.

The delay time of delay switch circuit is 1～10 second.But 1-3 second preferably.

Sample circuit can also further be specially:

Sample circuit is a kind of sensor, and it is electrically connected with the electric shock net.

Because the electric shock net can produce vibrations or electric spark behind the bump that stands human body or insect, can this physical signalling be converted into the signal of telecommunication by sensor and handle, and triggers delay switch circuit then and delays time.

Perhaps

Sample circuit is a capacitor charge and discharge loop, and it is electrically connected with high-voltage generator circuit.

The capacitor charge and discharge loop is according to when electric mosquito flap is in normal operating conditions, electric capacity is in the state that is full of electric charge, and once the electric shock net is clashed into by human body or insect, then high-voltage generator circuit can produce change in electric, this moment, electric capacity can begin discharge, thereby triggered delay switch circuit.

High-voltage generator circuit can also further be specially:

High-voltage generator circuit includes oscillating circuit, transformer and voltage doubling rectifing circuit, and connects in regular turn.

Begin starting of oscillation under the oscillating circuit power supply effect outside, make it to produce an alternating current, export this voltage by transformer then, carry out the supercharging rectification by voltage doubling rectifing circuit at last and handle, the output high voltage source.

The time-delay control output end of delay switch circuit is electrically connected with the control signal input of oscillating circuit.

Delay switch circuit can end effect to oscillating circuit by delay switch circuit with after oscillating circuit is connected, and makes it not starting of oscillation under the time-delay state, reaches time-lag action.

Sample circuit is a capacitor charge and discharge loop, and it is connected with a winding of transformer.

Because sample circuit is the capacitor charge and discharge loop, it can charge to electric capacity in the transformation process by transformer, and according to the transformation state of transformer: as being short-circuited because of being impacted when the electric shock net, this moment, the signal variation can take place in secondary side, thereby cause primary side to produce negative pressure, capacitor discharge.

Transformer is a kind of three-winding autotransformer.

Wherein first winding is vibration transformation primary side, and second winding is a self coupling sampling primary side, and the tertiary winding then is transformation output secondary side.

In sum, advantage of the present utility model is: come electric mosquito flap is clashed into the time-delay discharge by adopting delay switch circuit and sample circuit, be interrupted the problem of electric shock fast thereby solve effectively, improved the safety in utilization of electric mosquito flap human body generation injury.
