Embodiment Construction

[0039] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0040] Sound attenuation and sound insulation play an important role in the practicality of things. Among them, the sound attenuation refers to the property of weakening and reflecting the sound that reaches the object, and this property is abundant in porous materials such as glass fiber and rock wool. The sound attenuation of the material varies greatly with the frequency or incident angle of the sound. For example, porous sound-absorbing materials are effective for high-frequency sounds, but for low-frequency sounds, a better sound-absorbing effect needs to be achieved by incr...

Abstract

An embodiment of the invention provides a material measuring method and device, a dust collector and a control method of the dust collector, belongs to the technical field of electron, and solves theproblems that the cleaning rate of the dust collector is affected as cleaning surface materials are different in the prior art. The method is applied to the material measuring device arranged in the dust collector, the device comprises an ultrasonic transmitter and an ultrasonic receiver, the method includes the steps: transmitting ultrasonic waves to a cleaning surface; receiving reflection wavesof the ultrasonic waves; determining noise reduction rate corresponding to the cleaning surface materials through peak values in the reflection waves according to a preset relationship; adjusting rotating speed of a dust collector motor according to the noise reduction rate. The method is applicable to material measuring processes.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a material measurement method and device, a vacuum cleaner control method and the vacuum cleaner. Background technique [0002] At present, PSD (Position Sensitive detector, position sensitive detector) and pressure sensors are widely used in existing vacuum cleaners. For vacuum cleaners with PSD, although the distance between the vacuum cleaner and the ground can be accurately confirmed, it is difficult to obtain information on the material of the ground, and dust, foreign objects, etc. will also have a great impact on the PSD, making the vacuum cleaner ineffective in use. . For a vacuum cleaner with a pressure sensor, when the vacuum cleaner moves from a flat ground to a carpet, it senses that there is a pressure difference on the suction of the vacuum cleaner, thereby controlling the vacuum cleaner to increase the suction. However, the vacuum cleaner cleans many types of...
