Description

Conventional lithium battery tail charged diving electric torch

Technical Field

The utility model provides a conventional lithium battery tail charged diving electric torch, and relates to the technical field of diving electric torches.

Background

The diving flashlight is different from a land flashlight, and needs a higher waterproof grade, so that the charging hole is not exposed like the land flashlight or is simply dustproof and waterproof by a silica gel plug. For better waterproofing, there are two charging modes for common diving flashlights: one is to take out the lithium battery for charging, but this way is complicated, and an additional charger is required to increase the product cost. The other is to use a built-in lithium battery, but the method can only purchase a customized nonstandard battery, so that the cost is increased, and meanwhile, the inconvenience is brought to a user in searching for a substitute battery.

Therefore, we propose a conventional lithium electricity afterbody dive flashlight that charges, and the design of this dive flashlight need not provide any charger, just can utilize the cell-phone charger to charge for this flashlight, while reducing cost, caters for the environmental protection trend.

Detailed Description

Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 3, the utility model provides a conventional lithium-ion tail-charged submerged flashlight, which comprises a flashlight body 4, wherein the head of the flashlight body 4 is provided with an LED light source 1, a lithium battery 8 is arranged in the flashlight body 4, the tail of the flashlight body 4 is movably connected with a tail cover 5, the head of the flashlight body 4 is also provided with a driving module 2, the driving module 2 comprises a schottky diode 3, and specifically, the driving module 2 comprises a driving circuit, and a high-current schottky diode 3 is added on the driving circuit; the tail of the flashlight body 4 is further provided with a charging module 7 and a charging hole matched with the charging module 7, and a thimble 6 is arranged between the charging module 7 and the tail cover 5. Specifically, the charging module 7 includes a charging circuit.

Further, in the utility model, the positive electrode terminal of the schottky diode 3 is electrically connected with the positive electrode of the lithium battery 8, and the negative electrode terminal of the schottky diode 3 is communicated with the flashlight body 4.

Furthermore, the tail part of the flashlight body 4 is also provided with a spring and a conductive spring piece which are matched with the negative electrode end of the lithium battery 8, and the negative electrode of the lithium battery 8 is connected with the tail cover 5 through the spring, the conductive spring piece and the thimble 6.

Working principle: when the flashlight is in use, when the tail cover 5 is screwed on, the cathode of the lithium battery 8 is communicated with the tail cover 5 through the thimble 6 and then to the flashlight body 4, and finally to the cathode of the head driving circuit to form a loop. At this time, the flashlight body 4 is used as a cathode role to connect the cathode of the lithium battery 8 with the cathode of the driving circuit, and the schottky diode 3 can be used for normal illumination due to the unidirectional conduction principle of the schottky diode, so that the schottky diode 3 can not generate any influence on the original circuit, and only slightly changes the original driving circuit and structure.

When the tail cover 5 is unscrewed, the flashlight is in a charging state, the thimble 6 is separated from the tail cover 5, the flashlight body 4 is converted into a positive role, and the positive role is connected with the positive electrode of the lithium battery 8 through the diode, so that the lithium battery can be charged.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
