Description

Flashlight charging port protection structure and flashlight

Technical Field

The utility model relates to the field of lighting equipment, in particular to a flashlight charging port protection structure and a flashlight.

Background

Along with the continuous development and updating of the portable electric torch, the rechargeable electric torch is popular in the market due to the advantages of environmental protection, convenience and the like, especially USB charging has become one of the most mainstream and ideal charging modes of the rechargeable electric torch, and the charging port of the common rechargeable electric torch is integrated on the electric torch shell, so that a special charger and a charging wire are not required to be additionally arranged, and the battery in the electric torch can be charged only by using a charging head and the charging wire which are compatible with a mobile phone, thereby saving the cost and increasing the convenience of outdoor carrying.

Because the charging port of the existing rechargeable flashlight is generally located outside the flashlight shell, and particularly used as an outdoor rechargeable flashlight, the charging port is easy to enter dust, sediment and rainwater in the outdoor environment to damage a flashlight driving circuit, and therefore the charging port of the rechargeable flashlight has certain waterproof and dustproof capabilities. At present, a dust cover or a dust plug made of silica gel or rubber is additionally arranged at the position of a charging port of a charging flashlight in the market, and the charging port can be covered or plugged by the dust cover or the dust plug to a certain extent so as to solve the problems of water resistance and dust prevention due to elasticity of the silica gel or the rubber. When the flashlight needs to be charged, the dust cover or the dust plug covered on the charging port is pulled out, the charging port is exposed, the charging wire is inserted, and the dust cover or the dust plug is plugged again after the charging is completed.

However, the currently used method of dust cap at charging port still has many problems. Because the dustproof cover is small in size, the contact tightness between the dustproof cover and the charging port is reduced after long-term use, so that the dustproof cover is not firm in sealing, the dustproof effect is reduced, and the waterproof requirement is difficult to reach; on the other hand, the dust cover is installed in the outer wall of the flashlight through a relatively slender flexible connection, and after long-term use, the flexible connection is easy to break to cause the dust cover to fall off, so that the flashlight is easy to damage due to water inlet of the charging port under the condition that the dust cover falls off or is not tightly sealed.
