Ultrasonic alignment device of sweeper

Abstract

The invention discloses an ultrasonic alignment device of a sweeper. The device comprises an alignment backflushing main body and a sweeper body, the alignment backflushing main body is provided with a top ultrasonic transmitter, a left ultrasonic transmitter and a right ultrasonic transmitter, and the front face of the bottom of the alignment backflushing main body is provided with a positioning groove and an electrode plate. A protection mechanism is arranged at the bottom of the alignment backflushing body, a telescopic mechanism is arranged on the inner side of the top of the alignment backflushing body, the top end of the telescopic mechanism is connected with a pump body through a hose, and a dust collection box is arranged on one side of the pump body. The beneficial effects are that by arranging the top ultrasonic transmitter, the left ultrasonic transmitter and the right ultrasonic transmitter, accurate positioning of the aligning and backflushing main body can be achieved, and therefore the sweeper body achieves aligning and backflushing operation through the ultrasonic receiver at the top end of the sweeper body; and compared with the traditional method adopting the infrared guidance alignment, ultrasonic positioning has the advantages of being long in controllable distance, high in alignment precision and not prone to being shielded.

Description

technical field [0001] The invention relates to the technical field of alignment devices for sweeping machines, in particular to an ultrasonic alignment device for sweeping machines. Background technique [0002] The sweeping robot is a kind of smart home appliance, which can automatically complete the floor cleaning work in the room by virtue of certain artificial intelligence. Generally, the sweeping robot collects the ground debris and absorbs them into its own dust bucket through the side brush and fan at the bottom, so as to complete the function of ground cleaning, and the operator only needs to clean the dust bucket regularly. With the advancement of technology, more and more families use sweeping robots to reduce the burden of housework. After the working mode is turned on, it will automatically complete the floor cleaning work in the room, and when the power is insufficient, it can automatically return to the charging stand for automatic charging, reducing manual o...

Problems solved by technology

[0003] After the sweeping robot performs the cleaning task, it will automatically return to the charging device for charging. The existing sweeping robot sets the charging contact point, the middle infrared receiver and the auxiliary receiver. Alignment, alignment accuracy is not high

Moreover, at present, when the sweeping robot searches for the position of the charging seat at a long distance, it can only be completed by the middle long-distance infrared emission signal and the method along the wall, which takes a long time, slow speed and low efficiency.

In addition, most of the electrode pads of the existing recharging devices are exposed outside, and it is easy to accumulate dust when exposed to the external environment for a long time, which leads to the problem of unstable charging.

[0004] For the problems in related technologies, no effective solutions have been proposed yet
