Description

Self-propelled cleaning device and dust collecting method thereof

The present invention relates to a self-propelled cleaning device, and more particularly to a self-propelled cleaning device for cleaning work with autonomous displacement and a dust collecting method thereof.

Due to the busy work of modern people, it is a laborious and time-consuming task for house cleaning. In order to solve such problems, the so-called self-propelled cleaning device products appear on the market, and can be automatically grounded by artificial intelligence control. It is cleaned and dusted back and forth to achieve the convenience of no human operation.

A conventional self-propelled cleaning device, as shown in the first figure, includes: a body 1 including a dust suction mechanism 11 having a main sweeping brush 111 pivoted to a dust suction port 112, The main sweeping brush 111 sweeps the dust of the ground, and the dust of the ground is sucked into the body 1 by the dust suction port 112; the one side brushing mechanism 12 is disposed on the side of the body 1, and the dust outside the periphery of the body 1 is externally Sweeping toward the body 1 and sweeping and sucking by the dust collecting mechanism 11; a driving wheel set 13 for carrying the displacement of the body 1 on the ground; a dust collecting box 14 communicating with the dust collecting mechanism 11 for collecting and vacuuming The mechanism 11 draws in dust; a vacuum device 15 communicates with the dust box 14 to provide negative pressure suction through the exhaust port; and a control unit 16 can be used to determine the received signal transmission command to the drive wheel set 13 to control the body 1 displacement.

The dust-collecting method of the conventional self-propelled cleaning device pivots a main sweeping brush at the dust suction port, and it is desired to enhance the cleaning by sweeping the ground dust by the main sweeping brush. The effect is that the conventional self-propelled cleaning device is mostly designed with a single dust suction port and a single main sweeping brush. Although the main sweeping brush can be used to clean the floor, it blocks the dust suction space of the dust suction port; The dust can be divided into two major categories: heavy particles and light debris. The light debris contains human and animal hair, string, wire, carpet fiber and other fabrics that are easily stretched and wrapped around the main brush. The debris on the pile, the accumulated light debris can reduce the performance of the main sweeper in various ways, for example, it may cover the main sweep bristles and form additional friction to hinder the main sweeper rotation, in addition, if not These lightweight debris is removed and may accumulate at both ends of the main sweep and enter the bearing area, damaging the bearing or other unintended conditions, and the light debris accumulated on the main sweep may cause the main sweep. The imbalance causes the main sweep to produce noise or vibration while rotating, and the light debris accumulated on the main sweep is often difficult to remove because these lightweight scraps tightly wrap the main sweep and The bristles are tangled together Consumers often have to be self-propelled cleaning device upside down, then use the knife, scissors and other sharp knife ... such as debris clearing, manual removal is not only unsanitary and time consuming, and there is the risk of a sharp knife cut.

Therefore, the object of the present invention is to provide a hair avoiding Or a self-propelled cleaning device for dusting the main sweeping brush.
