Description

DC constant voltage circuit module

The invention relates to a DC constant voltage circuit module, in particular to a DC constant voltage circuit module which is multifunctional and practical, and can maintain the constant speed of the DC motor.

The DC constant voltage module of the present invention can be applied, for example, to a vacuum cleaner. The cleaning principle of the vacuum cleaner is to suck dust and dry from the surface of the floor, carpet, wall, furniture and other dirt that is not easy to be removed by the broom by means of suction. Dirty (eg food scraps, hair, etc.). Its main components are DC motors, filter bags (or filters), hoses, extension tubes and nozzles in a variety of shapes. Modern vacuum cleaners vary in accessories. They are designed to remove carpet dirt, rough brush, fine brush, rotating brush, flat nozzles for cleaning corners, polishing brushes for floor cleaning, etc., and vacuum cleaners can be used for other applications. In terms of items such as collecting items, finding small objects, and cleaning the electric appliance, the convenience of cleaning can be improved.

At present, vacuum cleaners have become very popular for families, especially those who have been covered with carpets on the ground, using dust and dust that are very difficult to remove by general brooms, and more need to use vacuum cleaners to perform cleaning work, but general vacuum cleaners are usually limited by The location of the indoor AC outlet is not free to be used in any corner. Even if the extension cord is added, it is also tied by the wire. It is still not convenient enough to use.

In addition, the vacuum cleaner is equipped with several different types of nozzles for cleaning different types of areas, but for narrower corners (such as: under large furniture, under the bed), because the naked eye is difficult In order to distinguish the location of dust and debris, it is easy to have a dead angle that cannot be cleaned. If it is used to find small objects, it is difficult to find because of small objects, and it is not enough light or is used indoor furniture (for example, bed or table and chair, etc. When the shadowing is too dark, it increases the difficulty of finding.

Furthermore, it is generally not known that portable or mobile vacuum cleaners are inconspicuous in indicating the amount of electricity. In the absence of an early warning, the battery of the vacuum cleaner is exhausted and cannot continue to operate, resulting in inconvenience to the user. In addition, whether it is a general vacuum cleaner, a portable vacuum cleaner or a mobile vacuum cleaner, the speed of the DC motor is adjusted to control the strength of the suction. Usually, two-stage (for example, strong and weak) or three-stage switches are used (for example: Strong, medium and weak) to adjust, the user sometimes can not adjust to the desired suction strength, and the commercially available vacuum cleaner is often still active when charging, so that children in the home accidentally touched Unnecessary damage can occur when working with a vacuum cleaner.

In view of the fact that the conventional vacuum cleaner lacks an effective method of speed regulation, illumination, display and safety protection, it is urgent to propose a novel mechanism, and the invention can provide a vacuum cleaner without step speed adjustment, illumination, display and safety protection.
