Abstract

The utility model relates to an electric megaphone that can display battery power, which comprises that a horn, a rear cylinder with a handle and a rear cover with a microphone are connected with each other into a whole, a battery, a charging line group, a charging jack and a battery power indicator light which are arranged in a whole; the battery, the charging line group and the charging jack are arranged on a battery box and the battery box is arranged at the open end of the rear cylinder; two or more battery power indicator lights arranged on the rear cylinder are respectively connected with the battery box by wires; in the electric megaphone, the batteries are arranged in the battery box in a concentrated way, so as to be convenient for the battery to be connected, exchanged and charged. Charging can be realized only by opening the rear cover and inserting an external charger into the charging jack, so that the battery is not required to be taken out from the battery box, thus realizing convenience and rapidness; three battery power indicator lights which respectively are red, yellow and green are arranged on the electric megaphone, so as to display the information about the battery power at any time and constantly remind the consumers of preparing for changing the battery or charging the battery in time, thus providing more convenience and indication for the work of the consumers.

Description

The megaphone that the charged pool electric weight shows

Technical field

The utility model relates to a kind of megaphone, and is particularly a kind of chargeable, and the megaphone of the charged pool electric weight demonstration of the big or small available indicator light demonstration of battery electric quantity.

Background technology

Along with improving constantly of people's living standard, tourist industry flourish, for satisfying the demand in market, relevant multi-functional, can throw light on, carry, megaphone easy to use arises at the historic moment, although various in style, the shape of existing megaphone, different sizes, but existing megaphone does not also have what prompt facility of complete battery electric quantity, can bring inconvenience and trouble for vast consumer's such as salesman, guide work.

Patent No. CN200320119071.0 " portable torch megaphone " is provided with the electric quantity of power supply indicator light though mention at the tail-hood rear side, and the effect of this indicator light only can point out the user will in time change battery, and function is also incomplete.

Summary of the invention

Technical problem to be solved in the utility model is: the megaphone that provides a kind of charged pool electric weight to show, except that chargeable, also can be at any time provide battery electric quantity what information to the consumer, being convenient to the consumer can shift to an earlier date, initiatively grasps, arrange battery charge or replacing battery, easy to use, provide a kind of new varieties of selecting use for different consumers for market simultaneously.

The technical scheme in the invention for solving the above technical problem is: the megaphone that the charged pool electric weight shows, comprise in the integral body that the bonnet of back tube, the band microphone of loudspeaker, band handle connects into, battery, charging circuit group, charging socket, battery electric quantity indicator light are installed, described battery, charging circuit group, charging socket all are installed on the battery case, described battery case is installed in the openend of back tube, two and plural battery electric quantity indicator light is installed on the tube of described back is connected with battery case with lead respectively.

Compared with prior art, advantage of the present utility model is: this megaphone is concentrated battery and is placed in the battery case, and the charging circuit group is installed in the cover plate box above battery case, and the charging socket is installed on the cover plate box wall, the positive and negative electrode of battery is arranged on the battery case base plate, be convenient to wiring, transposing, the charging of battery, during use, as long as open bonnet, it is just chargeable to allow the external charge device insert the charging socket, do not need battery is taken out from battery case, easy to use, quick.Red, yellow, green three battery electric quantity indicator lights are arranged on the megaphone in addition, can show at any time provides battery electric quantity what information, constantly remind the consumer to get ready in time to change battery or to battery charge, for consumer's work provides more convenience and prompting.

Fig. 4, structure of the present utility model are shown electrograph (taking away bonnet and battery case).

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Battery 15 is installed in the cavity of battery case 7 of openings at one side, battery case 7 upper surfaces are screwed the cover plate box 14 interior charging circuit groups 18 of installing that cover plate 17 forms, charging socket 19 is arranged on cover plate box 14 sidewalls, the positive and negative electrode 16 of battery pack is arranged, on the bottom surface of battery case 7 as Fig. 2, shown in Figure 3.

The handle 13 that has mains switch 12 is screwed on back tube 2, be equipped with on back tube 2 one side external surfaces and can show what red indicator light 3 of battery electric quantity, yellow indicator light 4, green indicator light 5 and hinge 11, hinge 11 is hinged to one with back tube 2 and bonnet 10, on the back tube of hinge 11 corresponding positions, be fixed with snap close 6 and cooperate with latch hook 8 on the bonnet 10, be fixed with dividing plate 20 on one side of tube 2 bottom surfaces, back, dividing plate 20 shapes and battery case 7 are complementary, as shown in Figure 4, on bonnet 10 end faces microphone 9 is installed, back tube 2 is screwed on the rear port of loudspeaker 1, as shown in Figure 1.

The battery case that assembles 7 inserts in the dividing plate 20 on the back tube 2, and battery 15 faces are close to back tube 2 inwalls, battery case 7 can not be rocked, as shown in Figure 1 in the tube of back.

The two ends usefulness lead of red, yellow, green indicator light 3,4,5 is connected with the battery positive and negative electrode 16 on the battery case 7.

Just can use megaphone as long as turn on the power switch 12, when battery 15 had just been brought into use for new battery, green indicator light was bright, and the battery electric quantity abundance is described, can relievedly use, As time goes on, the battery slow consumption, yellow indicator light is bright after electric quantity consumption surpasses 50%, remind the consumer alert, to be with reserve battery when going out or prepare charging, when battery consumption behind 70% the electric weight red indicator light bright, remind the consumer will change battery or charging in time immediately.
