DC constant voltage circuit module

Abstract

The invention discloses a DC constant voltage circuit module which can input electric power for operation by a battery module and automatically detects the voltage of the battery module, and voltage compensates the battery module when the voltage of the battery module is insufficient to To achieve the DC motor constant voltage and fixed speed purposes. The DC constant voltage circuit module disclosed in the present invention is provided on a main control integrated circuit board including a battery monitoring unit and a battery module which are coupled via a main control integrated circuit board and a DC motor terminal; wherein the battery The module controls the integrated circuit board for performing flow detection and control of the battery module so that the voltage released by the battery module is maintained at a constant voltage operating area which, when in operation, the main control integrated The circuit board adds voltage to the battery module through the micro control unit and the voltage supplement frequency detection unit.

Description

Technical field [0001] The invention relates to a DC constant voltage circuit module, in particular to a DC constant voltage circuit module with both multi-functions and excellent practicability, which can maintain a constant speed of a DC motor. Background technique [0002] At present, vacuum cleaners are very popular in households, especially where carpets have been laid on the floor of the home. The debris and dust that are very difficult to remove with ordinary brooms are required to perform cleaning tasks. However, ordinary vacuum cleaners are usually limited to indoor AC power The position of the socket cannot be used freely in any corner.

AI Technical Summary

Problems solved by technology

[0002] At present, vacuum cleaners are very popular in households, especially if the floor of the home is carpeted, it is very difficult to remove debris and dust with ordinary brooms, and it is necessary to use vacuum cleaners to perform cleaning tasks, but ordinary vacuum cleaners are usually limited by indoor AC power. The location of the socket cannot be used freely in any corner. Even after adding an extension cable, it is still hindered by the wire, and it is still not convenient to use.

[0003] In addition, although the vacuum cleaner is equipped with a variety of suction nozzles in different styles to clean different types of areas, for relatively narrow corners (such as: under large furniture, under the bed), it is difficult for the naked eye to distinguish the location of dust and debris. 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 due to insufficient light or covered by indoor furniture (such as beds, tables and chairs, etc.). case, it is more difficult to find

[0004] In addition, the general existing portable or mobile vacuum cleaners do not have a clear indication of the power. Often without warning, the battery of the vacuum cleaner is exhausted and cannot continue to work, 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 DC motor to control the strength of the suction, usually use a two-stage switch (such as: strong and weak) or a three-stage switch (such as : strong, medium and weak) to adjust, users sometimes cannot adjust to the desired suction strength, and commercially available vacuum cleaners often can still work when charging, so that when a child accidentally touches the vacuum cleaner at home, it will still work. Unnecessary injury can occur when working with a vacuum cleaner

[0005] In view of the fact that the traditional vacuum cleaner lacks an effective way of speed regulation, lighting, display and safety protection, it is urgent to propose a vacuum cleaner with stepless speed adjustment, lighting, display and safety protection
