Description

rechargeable vacuum cleaner

technical field

The utility model relates to a rechargeable vacuum cleaner, in particular to a rechargeable vacuum cleaner with multiple functions and excellent practicability.

Background technique

The cleaning principle of the vacuum cleaner is to use suction to suck away dust and dry dirt, such as threads, paper scraps, hair, etc., from floors, carpets, walls, furniture and other surfaces that are not easy to remove dirt with a broom. Its main components are motors, filter bags (or filter screens), hoses, extension tubes and nozzles of various shapes. Modern vacuum cleaners have a variety of accessories. For removing carpet dirt, coarse brushes, fine brushes, and rotating brushes are designed. Flat nozzles are used to clean corners, and polishing brushes are used to clean floor analysis. In other aspects, such as collecting items, finding small objects, cleaning electrical appliances, etc., the convenience of cleaning is greatly improved.

At present, vacuum cleaners are very popular in households, especially those with carpets on the floor of the home. It is very difficult to remove debris and dust with ordinary brooms, and it is necessary to use vacuum cleaners to perform cleaning tasks. The location of the indoor AC socket cannot be used freely in any corner. Even after adding an extension cable, it is still not convenient to use because it is still hindered by the wire.

In addition, although the vacuum cleaner is equipped with several different types of nozzles to clean different types of areas, for darker corners (such as under large furniture, under the bed), it is difficult to distinguish the position of dust and debris with the naked eye. There are likely to be blind spots that cannot be cleaned. If it is used to find small objects, it is difficult to find small objects, and it is too dark when the light is insufficient or covered by indoor furniture (such as beds, tables and chairs, etc.) , increasing the difficulty of finding.

Furthermore, portable or mobile vacuum cleaners do not have a clear indication of the power, and often without warning, the battery of the vacuum cleaner is insufficient in power and cannot continue to operate, causing inconvenience to the user. In addition, whether it is a general vacuum cleaner, a portable vacuum cleaner or a mobile vacuum cleaner, to adjust the speed of the motor to control the strength of the suction, usually use a two-stage switch (for example: strong and weak) or a three-stage switch (for example: strong, medium and weak) to adjust, the user can never adjust to the desired suction strength, and the vacuum cleaners on the market often still work when charging, so that when a child accidentally touches the vacuum cleaner at home Unnecessary damage will occur when the vacuum cleaner is in operation.

Since the traditional vacuum cleaner lacks an effective way of speed regulation, lighting, display and safety protection, it is urgent to propose a novel mechanism that can have a vacuum cleaner with stepless speed adjustment, lighting, display and safety protection.
