Abstract

To solve problems in the past that a connection failure occurs due to disconnection of a plug of a power cable, etc., there is a concern that the battery expands when deterioration progresses, which may eventually cause generation of heat, generation of smoke, rupture, etc. and a battery is protected against shock by being separated from a fan side and stored in a pocket.SOLUTION: A battery pack 33 is configured so that a housing 35 is inserted in a hollow part 26 of a battery installation part 25. Therefore, if the housing 35 expands even slightly, it must be pressed in strongly, and if it further expands, the insertion becomes impossible, so that if the expansion occurs even slightly, it can be detected easily. Also, the battery back 33 is guarded by the housing 35 when installed so that the battery pack 33 is prevented from being deformed or damaged even when shock is applied. By integrating a fan and a battery, a problem accompanying use of a power cable can be eliminated. At the same time, sufficient safety measures are taken for the battery.SELECTED DRAWING: Figure 4
