Claims

[Claims for Utility Model Registration] 1. A control device for a rechargeable vacuum cleaner with a flashlight, which includes a charging control device, a DC blower, and a secondary battery, wherein the secondary battery includes the DC blower and a flashlight bulb. a voltage detecting section for detecting the voltage between the terminals of the secondary battery in a load circuit for the bulb load of the secondary battery, and a constant current supplying a constant current to the bulb; A current that controls the constant current circuit so as to supply two or more sets of constant currents to the light bulb, which are different until the voltage between the terminals of the secondary battery reaches a certain set value and when it is below the set value. A switching section is provided,
A control device for a rechargeable vacuum cleaner with a flashlight configured to be able to switch discharge current in multiple stages according to the voltage between terminals of the secondary battery. 2. The pocket pocket according to claim 1 of the utility model registration, characterized in that the current switching unit operates the charging advance warning means at the same time as switching the current value when the voltage between the terminals of the secondary battery is below a set value. Control device for rechargeable vacuum cleaner with electric light.
