Description

A kind of sweeping robot

Technical field

The utility model relates to the technical field of domestic robot, a kind of specifically sweeping robot.

Background technique

Currently on the market all sweeping robot cleaning modes be sweep suction combination, machine advance when round brush to (rotation direction identical as driving wheel) is rotated afterwards, the scraping article at round brush rear is recycled to block the rubbish got rid of backward, last resort blower Rubbish is sucked dust barrel by the centrifugal force of suction and round brush rearward.The gas outlet of the sweeping robot of this traditional approach, blower is straight Run in into atmosphere, not only cause that the waste of the energy keeps the utilization rate of the energy low but also the noise of blower is big, influences home life Environment.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of sweeping robots, can change the side of dust suction Formula is not only energy utilization rate height, and equipment noise is small.

Technical solution adopted in the utility model is: providing a kind of sweeping robot, it includes casing, is equipped in casing The bottom of dust-collecting cavity, the casing is equipped with suction inlet, is connected between suction inlet and dust-collecting cavity by input channel, feature exists It further include being penetrated for driving the air in input channel towards the jet stream mechanism flowed in dust-collecting cavity in: the sweeping robot The return flow line of exhaust outlet of the building one for being connected to jet stream mechanism and dust-collecting cavity, the reflux are logical between stream mechanism and dust-collecting cavity Road is equipped with the air accelerator for driving the air in return flow line to flow towards jet stream organization location.By air plus Guiding role of the high-speed flow through jet stream mechanism that fast device generates can drive the air in suction inlet towards flowing in dust-collecting cavity, complete At dust suction process, while the additional air being discharged in dust-collecting cavity is delivered to the recycling that air is realized in air accelerator again, The consumption of the energy is greatly saved in the above process on the basis of guaranteeing dust-absorbing function, therefore energy utilization rate is high, same to space-time Gas circulates in casing internal, therefore reduces the wind that air outlet generates and make an uproar, therefore the noise of equipment operation is small.

The jet stream mechanism includes several jet stream mouths of the circumferential array along suction inlet, and whole jet stream mouths is directed toward suction inlet And it is tilted towards input channel, jet stream mouth is connected to return flow line respectively by respective supply air line.

The jet stream mouth is the through-hole that casing is recessed on the position of suction inlet, and the supply air line is set to It is connected in casing and with corresponding jet stream mouth.

It is equipped with the round brush being rotatably assorted with casing in the suction inlet, is placed with several stomatas on round brush, in round brush It is equipped with a central passage along own axes direction, the stomata is connected to by central passage with return flow line.Pass through central passage Can making round brush with the stomata arranged on round brush, there is also the air-flows sprayed radially outward during rotation, thus improve rolling The centrifugal force of brush to be conducive to raise dust granules, and gets rid of dust granules under the influence of centrifugal force into input channel It is interior.

Driving motor is equipped in the casing, the output end of driving motor is connect by transmission component with round brush, the biography A housing is arranged with outside dynamic component, return flow line is connected to by the inner cavity of housing with the central passage in round brush.It is by housing It can achieve the protective action for transmission component, while using the cavity in housing as airflow channel, not only having saved gas The installation space of circulation road, and self-cleaning is realized for transmission component.

The bottom of the casing is located at suction inlet and is equipped with bottom and ground so that casing away from the side of casing direction of travel The air curtain generators of air wall are formed between face.The scraping article of the prior art can be replaced by air wall, therefore will not generate biography The rubbish band for comparing concentration together is left at generally existing scraping article in system sweeping robot, while the old of scraping article that will not hesitate Change and causes to clean the problem of unclean or aging is repaired.

The air curtain generators are the exhaust outlet of bar shaped, are equipped in casing for being connected to the auxiliary of exhaust outlet and return flow line Help air supply channel.

The air accelerator is set to dust-collecting cavity along the front of casing direction of travel, and the dust-collecting cavity accelerates away from air There are the reserve chambers for installing auxiliary accessories at the rear of device.Due to changing dust suction mode, nothing on the lateral wall of casing The gas vent being vented outwardly need to be set, so air accelerator is also just without being set to casing rear end close to the position of gas vent, because This, air accelerator is set in front of dust-collecting cavity and makes dust-collecting cavity rear there are reserve chamber, not only reduce air accelerator with Pipeline size between dust-collecting cavity keeps installation space more compact, and function accessories can be set in reserve chamber, improve equipment Function.

After using the above structure, a kind of sweeping robot of the utility model has the advantage that compared with prior art Firstly, air circulation uses, therefore energy utilization rate is high, secondly, be not necessarily to outer air-discharging, therefore wind is made an uproar small, is suitable for household and is used, Thirdly, stomata is had on round brush, structure is simple and the cleaning effect of round brush can be improved, therefore good dedusting effect, finally, sharp Can produce air wall with air curtain generators and substitute traditional scraping article, after cleaning process will not there are traces, while without Influence of the consideration scraping article aging for cleaning effect, therefore cleaning effect is good, long service life, maintenance cost is low.
