Abstract

The utility model relates to a circuit device which consists of a table lamp shell, a charging circuit, a flashlight circuit, a flashlight shell and a helix spring. The circuit device has the double functions of flashlight and table lamp. The charging circuit is formed by electrically connecting a power supply plug, a power supply socket, a switch K1, a charger and a DC plug in serial. The flashlight circuit is formed by electrically connecting a DC socket, a contactor, a charging circuit, a bulb, a switch K2, a conductive sheet and a b contactor. The conductive sheet and the contactors a and b of the flashlight circuit are respectively connected in touch manner. The charging battery is connected with the bulb in parallel. When the DC plug and the DC socket are connected with each other, the conductive sheet which electrically communicates the contactors a and b in the effect of the helix spring is moved backwards by the DC plug to remain the a and b contactors staying in cut state; and at the time, if the switch K1 of the charging circuit is closed, the charging circuit which is powered on can charge the charging battery. The DC plug and the DC socket are separated if the charging flashlight is needed to be used independently.

Description

Has the bifunctional circuit arrangement of torch and desk lamp

Affiliated technical field

The present invention relates to a kind of circuit arrangement, particularly a kind of existing torch charge function has the circuit arrangement of desk lamp function again.

Background technology

As everyone knows, Rechargeable torch is more and more used by people.But because application time, the application site of torch all have very big uncertainty and random, the torch after therefore using is usually shelved conveniently by people.Just because of this, when people use torch again, usually want spended time to go to seek it.For this reason, we can be such the imagination: if relatively-stationary desk lamp housing of Rechargeable torch and place and circuit thereof can be combined: promptly, allow Rechargeable torch become the illumination section of desk lamp, no matter when people use torch, it is taken off from the desk lamp housing just can like this.

Summary of the invention

The objective of the invention is: Rechargeable torch is carried out combining of some necessity with desk lamp, do like this: one, make torch that a fixing placement location be arranged, remove the searching of people to torch; Its two, can not forget and charge to torch.Find no identical invention by retrieval.

A kind of have torch and a bifunctional circuit arrangement of desk lamp, and it is to be formed by desk lamp housing, charging circuit, torch circuit, flashlight shell, helical spring group connection; The desk lamp housing by seat shell, circuit conduit fixedly UNICOM form, present shell is provided with the through hole A that is used to import power line, is used for fixing K switch ₁Through hole B and be used for fixing the through hole G of supply socket, the other end of circuit conduit is provided with external screw thread M; The middle part of flashlight shell is provided with and is used for fixing K switch ₂Through hole F; Its tail end is provided with the through hole E that has internal thread that matches with its external screw thread of circuit conduit M, and under the charged state, this through hole E and external screw thread M are to revolve and join shape; Charging circuit is by attaching plug, supply socket, K switch ₁, charger, DC plug electrically connect formation successively; The torch circuit is by DC socket, a contact, rechargeable battery, bulb, K switch ₂, conduction connection sheet, b contact be and electrically connect formation, and two contacts of a, b in conduction connection sheet and the torch circuit are respectively and touch the connection shape, rechargeable battery is shape in parallel with bulb; Helical spring one end acts on the conduction connection sheet of torch circuit, and the other end is the inwall that is fixed on flashlight shell of the shape that insulate.

The present invention is because with the illumination section of Rechargeable torch as desk lamp, therefore, a fixing place that fetches just arranged when using Rechargeable torch; In addition, because the power supply of charging circuit and the desk lamp of torch keeps connection under the normal condition, so the problem of charging can not appear forgetting in Rechargeable torch.

Description of drawings

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

Figure 1 shows that structural representation of the present utility model, and have desk lamp housing schematic diagram concurrently.

Fig. 2 is the charging circuit schematic diagram.

Fig. 3 is the torch circuit diagram.

Fig. 4 is the flashlight shell structural representation.

Among each figure, 1, the seat shell, 2, circuit conduit, 3, through hole A, 4, through hole B, 5, charging circuit, 6 attaching plugs, 7, supply socket, 8, K switch ₁, 9, charger, 10, DC plug, 11, the torch circuit, 12, DC socket, 13, rechargeable battery, 14, bulb, 15, K switch ₂, 16, conduction connection sheet, 17, flashlight shell, 18, through hole F, 19, through hole E, 20, helical spring, 21, through hole G, 22, the desk lamp housing.

The specific embodiment

Torch circuit as shown in Figure 3, when torch circuit (11) and charging circuit (5) shown in Figure 2 after the slotting company of DC plug (10) and DC socket (12), originally down two contacts of a, b being given the logical conduction in Electricity Federation in helical spring (20) effect joins sheet (16) and moves after by DC plug (10), make two contacts of a, b be off-state, at this moment as if K switch with charging circuit (5) ₁(8) closure so, has been connected the charging circuit (5) of power supply and can have been implemented charging to rechargeable battery (13) by attaching plug (6), be illustrated in figure 1 as the charging shape.

When people went out to carry Rechargeable torch, outward winding the through hole E with internal thread and the revolving of external screw thread M of circuit conduit (2) were joined, and DC plug (10) were extracted get final product in DC socket (12).

In addition, this invention also is provided with supply socket (7), and therefore, this device in use also can satisfy the demand of people to power supply.

Claims

1. one kind has torch and the bifunctional circuit arrangement of desk lamp, and it is to be formed by desk lamp housing, charging circuit, torch circuit, flashlight shell, helical spring group connection; It is characterized in that: charging circuit is by attaching plug, supply socket, K switch ₁, charger, DC plug electrically connect formation successively; The torch circuit is by DC socket, a contact, rechargeable battery, bulb, K switch ₂, conduction connection sheet, b contact be and electrically connect formation, and two contacts of a, b in conduction connection sheet and the torch circuit are respectively and touch the connection shape, rechargeable battery is shape in parallel with bulb; Helical spring one end acts on the conduction connection sheet of torch circuit, and the other end is the inwall that is fixed on flashlight shell of the shape that insulate.
