Problems solved by technology

[0012] First, the existing control unit adjusts the suction force of the vacuum cleaner in a sliding manner, and it will be difficult to adjust the suction force of the vacuum cleaner according to the amount of foreign matter that needs to be cleaned.
[0013] Second, there are no other indication signs or devices other than the working sound of the vacuum cleaner or the scale line of the sliding control part, so it is difficult for the user to judge the current operating mode or operating status of the vacuum cleaner
[0014] Third, when there are foreign objects blocking the air suction and discharge passages, or there are a lot of foreign objects accumulated in the dust bucket, the suction force of the vacuum cleaner will become smaller and the cleaning efficiency will be reduced

Abstract

The invention relates to an operation instructor of vacuum dust collector. Wherein, it comprises a power provider for powering the vacuum dust collector; an operation mode input for inputting the operation mode of dust collector; an operation mode display for displaying the input mode; a sound reporter for reporting the input operation mode with voice; and a controller for controlling the display and the sound reporter via the input signal of mode input. The invention can automatically adjust the adsorption force of collector based on foreigner mass, and user can watch the operation mode or state easily.

Description

technical field [0001] The present invention relates to a vacuum cleaner, in particular to an informative apparatus of a vacuum cleaner which broadcasts the operating status of the vacuum cleaner with sound. Background technique [0002] Figure 1 shows the structure of a prior art vacuum cleaner. As shown in the figure, a general vacuum cleaner is composed of the following parts: a vacuum cleaner body 10 with a suction device for sucking indoor air and foreign matter and a dust filter for removing foreign matter is built in, and a vacuum cleaner body 10 that uses the suction generated by the vacuum cleaner body 10 to suck in external air containing foreign matter. Mouth (nozzle)1. [0003] In addition, the following parts are sequentially connected between the vacuum cleaner body 10 and the suction nozzle 1: a suction hose 5 made of a soft material, connected to one end of the suction hose 5 and having a handle 6 of the control unit 4 for adjusting the working state of the ...
