Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a method for intelligently adjusting the rotating speed of a motor of a dust collector comprises the following steps:

1) a dust concentration sensor in an air duct pipe of the dust collector detects the dust concentration in the air duct pipe of the dust collector and transmits a detection signal to the control module;

2) the control module receives a detection signal sent by the dust concentration sensor and calculates and obtains an ideal working gear of the rotating speed of the dust collection motor according to a set rotating speed control scheme of the dust collection motor;

3) the control module sends a control instruction to a motor driving circuit of the dust collection motor, so that the rotating speed of the dust collection motor is switched to an ideal working gear from a current working gear.

In the step 3), the rotating speed working gear of the dust collection motor comprises a first gear, a second gear and a third gear, and when the dust concentration C in the air duct is less than or equal to C1, the ideal working gear of the rotating speed of the dust collection motor is the first gear; when the dust concentration C in the air duct pipe is greater than C1 and C is less than or equal to C2, the ideal working gear of the rotation speed of the dust collection motor is a second gear; when the dust concentration C in the air duct pipe is greater than C2, the ideal working gear of the rotation speed of the dust collection motor is the third gear. When the rotating speed of the dust collection motor is in a first gear, the rotating speed is lowest; the rotating speed of the dust collection motor is in the third gear, and the rotating speed is highest.

The control module is connected with the manual control switch, an operator operates the manual control switch, a control instruction is sent to a motor driving circuit of the dust collection motor through the control module, and the rotating speed of the dust collection motor is manually controlled to switch working gears. The rotating speed of the dust removal motor of the dust collector can be controlled through the manual control switch, and the rotating speed of the dust removal motor can be adjusted more flexibly, so that the dust collector can better deal with different dust removal environments.

When the dust absorption motor starts, the working gear of dust absorption motor rotational speed is the second gear, fully guarantees the suction of dust catcher when the dust absorption motor starts on the one hand, and on the other hand when avoiding the dust absorption motor after starting to carry out the gear switching, needs once switch over two gears, guarantees the steady of motor rotational speed adjustment, guarantees the life-span of dust absorption motor.

The dust concentration sensor comprises a dust sensing transmitter and a dust sensing receiver, the dust sensing transmitter and the dust sensing receiver are arranged in the air duct pipe oppositely, and the signal output end of the dust sensing receiver is electrically connected with the signal input end of the control module. The dust sensing transmitter is an infrared transmitter, and the dust sensing receiver is an infrared receiver. The working principle of the dust concentration sensor is as follows: the particles and molecules can generate light scattering phenomenon under the irradiation of light, and simultaneously absorb part of the energy of the irradiated light, when a beam of parallel monochromatic light is incident to a measured particle field, the light intensity is attenuated under the influence of scattering and absorption around the particles, so that the normal relative attenuation rate of the incident light passing through the measured concentration can be obtained, and the relative attenuation rate basically reflects the relative concentration of dust in the measured field linearly. The dust sensing receiver in the air duct receives signals sent by the corresponding dust sensing transmitters, so that the dust concentration is measured, and the detection signals are transmitted to the control module to control the rotating speed of the dust collection motor.

The working principle is as follows: when the dust collector faces different dust removal environments, a dust concentration sensor is arranged in an air duct pipe of the dust collector to detect the dust concentration in the dust collector, the control module judges an ideal working gear at which the rotating speed of the dust collection motor is required to be located according to a received detection signal (dust concentration index), then the rotating speed of the dust collection motor is controlled to be switched to the ideal working gear from the current working gear, the rotating speed of the dust collection motor is flexibly adjusted, the suction force of the dust collector is guaranteed, and the dust removal effect is guaranteed. In order to enable the dust collector to better cope with different dust removal environments, the rotating speed of a dust removal motor of the dust collector can be controlled by a manual control switch. When the rubbish that the dust catcher absorb is the great particulate matter of density (like the small stone), dust concentration sensor is when carrying out the detection of dust concentration, and the dust concentration that shows is lower, and under the normal condition (control module is in intelligent automatic control dust absorption motor rotational speed mode promptly) the rotational speed of dust absorption motor can be in lower first grade, leads to the dust removal effect not good. The setting of the manual control switch enables the control module to be switched between an automatic control mode and a manual control mode. When the manual control switch is turned on, the control module is switched to a manual control mode, the manual control switch comprises three gear switch buttons which are in one-to-one correspondence with 3 working gears of the rotating speed of the dust collection motor, the corresponding gear switch buttons are switched on to enable the rotating speed of the dust collection motor to be in different working gears (a first gear, a second gear and a third gear), and the rotating speed of the dust collection motor is not adjusted according to dust concentration. When the gear switch button is switched off, the manual control mode is released, the control module restores the automatic control mode, and the working gear of the rotating speed of the dust collection motor is automatically adjusted according to the dust concentration.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
