Technical Field
[0001] The present application relates to the field of lighting technology, and in particular to a hybrid flashlight. Background Art
[0002] At present, most flashlights are powered by a battery, either a dry cell or a rechargeable battery. If only a dry cell is used, it will cause frequent battery replacement, which is troublesome; if only a rechargeable battery is used, it will take several hours or even more than ten hours to charge the rechargeable battery when it is exhausted, which limits the application of the flashlight. For example, when working outdoors, the battery cannot be charged in time when it is out of power, which will cause trouble to the user.
[0003] In view of the above problems, China has applied for a patent "A flashlight", application number: CN201010159672.9; discloses a flashlight body having a head and a barrel, the head having a light source, the barrel having a battery cavity for placing dry batteries, and a tail cover, the bottom of the battery cavity having a positive contact, and the tail cover having a negative contact; the flashlight also includes a filling block adapted to the rechargeable battery, the filling block is adapted to the battery cavity after being combined with the rechargeable battery; the rechargeable battery has a first end and a second end, the first end of the rechargeable battery has a positive electrode for contacting the positive contact of the battery cavity, and the second end of the rechargeable battery has a negative electrode; the filling block has a first end and a second end, the first end of the filling block has a negative electrode for contacting the negative electrode of the second end of the rechargeable battery, the second end of the filling block has a negative electrode for contacting the negative electrode of the tail cover, and the negative electrode contact of the filling block is connected to the negative electrode through a conductor. In the above patent application, by adding a filling block, the flashlight can be powered by both rechargeable batteries and ordinary dry batteries.
[0004] However, although the flashlight in the above patent application can be powered by both rechargeable batteries and ordinary dry batteries, there is only one battery cavity designed inside the flashlight, and only rechargeable batteries or dry batteries can be placed in the flashlight. If the user suddenly runs out of power while using it, it is highly likely that the user will not carry spare dry batteries or rechargeable batteries with him / her, which cannot effectively solve the problem of the flashlight suddenly running out of power, or the situation where the flashlight needs to work for a long time.
