Problems solved by technology

[0002] The existing portable and upright two-in-one vacuum cleaners use a single battery pack for power supply. The battery pack is set in the portable vacuum cleaner. Vacuum cleaner, when the portable vacuum cleaner is put back into the upright vacuum cleaner, the battery pack supplies power to the upright vacuum cleaner. The portable vacuum cleaner is mainly used for sofas, curtains and other places that are not convenient for upright vacuum cleaners, and the use of upright vacuum cleaners involves To all the floors in the home, in order to facilitate the use of users, portable vacuum cleaners have certain requirements for weight and volume, so the battery pack in the portable vacuum cleaner has limited power, and generally can only guarantee the use time of about 15 minutes. 15 minutes seems like too little time for an upright vacuum cleaner

Abstract

The invention discloses a dust collector powered by two battery packs and relates to a power supply circuit of a handhold-type and vertical-type combined dust collector. A first battery pack capable of independently powering is arranged in a handhold-type dust collector body, a second battery pack is arranged in a vertical-type dust collector body, the handhold-type dust collector body and the vertical-type dust collector body are combined, the first battery pack and the second battery pack are parallelly connected to power a vertical-type dust collector, and power supply time of the vertical-type dust collector is effectively prolonged. The invention further discloses a discharging control method of the dust collector. Voltage of the battery packs is detected, and when the battery packs are larger than set voltage difference, power supply of the battery pack smaller in voltage is stopped timely, and damage to the battery packs due to reverse charging is prevented.

Description

technical field [0001] The invention relates to a power supply circuit of a vacuum cleaner, in particular to a vacuum cleaner powered by a double battery pack and a discharge control method based on the power supply of the double battery pack. Background technique [0002] The existing portable and upright two-in-one vacuum cleaners use a single battery pack for power supply. The battery pack is set in the portable vacuum cleaner. Vacuum cleaner, when the portable vacuum cleaner is put back into the upright vacuum cleaner, the battery pack supplies power to the upright vacuum cleaner. The portable vacuum cleaner is mainly used for sofas, curtains and other places that are not convenient for upright vacuum cleaners, and the use of upright vacuum cleaners involves To all the floors in the home, in order to facilitate the use of users, portable vacuum cleaners have certain requirements for weight and volume, so the battery pack in the portable vacuum cleaner has limited power, ...
