Handheld vacuum cleaner

Abstract

An embodiment of the present invention relates to the field of wireless vacuum cleaners and discloses a handheld vacuum cleaner. In the present invention, the handheld vacuum cleaner comprises a vacuum cleaner body, a battery of the handheld vacuum cleaner is arranged in the vacuum cleaner body, a main suction port and a power management mechanism are arranged on the vacuum cleaner body, a first conductive terminal, a second conductive terminal and a common ground terminal are arranged on the power management mechanism, wherein when the first conductive terminal communicates with the common ground terminal, the power management mechanism acquires power supply current to charge the battery of the handheld vacuum cleaner, and when the second conductive terminal communicates with the common ground terminal, the power management mechanism outputs working voltage to the outside for the handheld vacuum cleaner to work. According to the handheld vacuum cleaner provided by the embodiment of the invention, the handheld vacuum cleaner can be directly placed on a charging base for charging after the work is completed without taking the battery out of the vacuum cleaner body and without usingother switching devices.

Description

technical field [0001] Embodiments of the present invention relate to the field of cordless vacuum cleaners, in particular to a handheld vacuum cleaner. Background technique [0002] With the development of electronic technology, smart home has become more and more popular. Taking vacuum cleaners as an example, from the original wired vacuum cleaners to the current wireless vacuum cleaners, the design has become more and more user-friendly, and the functions have become more and more abundant, which greatly facilitates the use of users. [0003] However, the inventor has found that there are at least the following problems in the prior art: although the cordless vacuum cleaner gets rid of the shackles of the power cord during use, it can be convenient for users to use anywhere, but the vacuum cleaner body of the common handheld vacuum cleaner currently on the market The two conductive terminals set only have the function of connecting with the suction pipe and providing wor...

Problems solved by technology

[0003] However, the inventor has found that there are at least the following problems in the prior art: although the wireless vacuum cleaner is free from the shackles of the power cord during use, it can be convenient for users to use anywhere, but the vacuum cleaner body of the common hand-held vacuum cleaner currently on the market The two conductive terminals set only have the function of connecting with the suction pipe and providing working voltage for the handheld vacuum cleaner. When the battery of the handheld vacuum cleaner needs to be charged, the charging base cannot communicate with the existing two conductive terminals.

If you want to charge the battery of a handheld vacuum cleaner, you need to connect an external adapter or take the battery out of the vacuum cleaner body to achieve charging, which undoubtedly increases the preparation cost and the charging process is cumbersome
