Dust collection device

Abstract

The invention discloses a dust collection device. The problems of poor collection effect and high electricity consumption amount of a dust collection device in the prior art are solved. A method adopted by the dust collection device for controlling an air suction motor to work comprises the following steps that 1, data is initialized; 2, when a waste sensor senses waste, a pulse number M, a pulsewidth value R and a pulse width change value delta R start to be calculated; 3, the pulse number M at the moment when preset time T is up is recorded, and a first pulse threshold value M1, a second pulse threshold value M2 and a pulse width change threshold value S are preset in a control circuit, wherein M1 is smaller than or equal to M2, and if the pulse number value M is smaller than or equal to M1 and the pulse width change value delta R is smaller than or equal to S, the first step is returned to; if M is larger than or equal to M1 and smaller than or equal to M2, the pulse width change value delta R is smaller than or equal to S, and the pulse width value R is decreased, the firs step is returned to; if the pulse number value M is smaller than or equal to M1, the pulse width change value delta R is smaller than or equal to S, and the pulse width value R is decreased, a PWM value output by the control circuit is decreased, and the rotation speed of the air suction motor is lowered; otherwise, the PWM value output by the control circuit is increased, and the rotation speed of the air suction motor is increased.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a dust collection device. Background technique [0002] The dust collection device mainly uses the motor to drive the blades to rotate, and generates air negative pressure in the airtight casing to absorb dust. Due to the difference in the type and size of the garbage, the larger garbage is often judged as a single body, no matter what kind of garbage it absorbs. The rotation speed of the motor and the rolling brush is constant, and the larger garbage cannot be normally sucked in due to the constant suction force, and at the same time, when the smaller and dense dust is sucked, it is easy to cause a waste of electric energy. [0003] In order to solve the above problems, the prior art provides a vacuum cleaner using infrared, including a motor control circuit for controlling the normal operation of the motor, a microcontroller as a control center, a display module fo...

Problems solved by technology

However, the specific intelligent processing in the above scheme is mainly for the display module to remind the user, and the user then operates the buttons to adjust the suction of the vacuum cleaner, and manually adjusts the power and suction of the vacuum cleaner. Matching will also cause garbage to be unable to be sucked in quickly or waste of electric energy
