Description
Technical field
For the present invention in relation to a kind of robot, espespecially a kind of dust-collecting box of clean robot includes dialling to inhale device.
Background technique
Smart home is unconsciously penetrating into life various aspects, and especially in intelligent appliance, clean robot can
To be one of the household electrical appliances of relative maturity, by the control of artificial intelligence, clean robot can be in unmanned the case where manipulating
Under, automatically cleaning and dedusting back and forth on the ground.
Cleaning performance is one of the emphasis that clean robot considers, and cleaning effect can setting with brush and dust extractor
It both counts difference and different, and needs and cooperate, otherwise cleaning effect will have a greatly reduced quality, such as U.S. patent Nos the
No. 7200892, propose that a kind of brush can be with the structure adjusted by cleaning ground, and brush rear is equipped with a suction inlet, and in
Brush and suction inlet spacing have guiding airflow design, allow the soil after being cleaned by brush to be led to suction inlet and draw collection.
For another example TaiWan, China patent of invention I481377 proposes a self-propelled cleaning device, and tool is there are two negative pressure suction inlet, one
Positioned at the opposite front of walking path, another is located at walking path and is promoted clear with respect to rear using the design of multiple suction inlet
Clean efficiency.
So, in cleaning mode above-mentioned mostly be that soil is allocated to suction inlet using brush, because carpet be nonplanar quilt
Clean surface, such mode simultaneously can not reach cleaning effect, because brush on the market is usually the flexible flexible material taken, such
In environment and it can not be successfully and lift soil, it therefore, also can not be single even if clean robot has the design of multiple suction inlet
The soil of carpet root is sucked with negative pressure, so being to truly have improvedd necessary project.
Summary of the invention
In view of the above subject, a kind of dial inhales device and its dust-collecting box and its clean robot according to the present invention, using dialling
The auxiliary actuation for inhaling device improves the cleaning effect of clean robot.

Wherein, the periphery of multiple prominent tube bodies equipped with multiple thirds be open, multiple third open communication external environments with
Multiple protrusion tubular bodies.
Wherein, the surface of multiple protrusion tube bodies and dust-collecting box is in 90 degree or any tilt angle.
For the above-mentioned purpose with effect, it includes shell and above-mentioned group of suction device that the present invention, which provides a kind of dust-collecting box,.
Wherein, which includes:
One shell, the shell are placed in a clean robot, which includes:
One accommodating space, the accommodating space are set to the enclosure interior, accommodate the soil being inhaled into；
One air stream outlet, it is opposite which is set to the shell, and is connected with the accommodating space；And
The air flow inlet, the air flow inlet are set to the side that the shell faces surface to be cleaned；
One case top lid, the case top lid can assemblings corresponding with the shell；
One strainer, the strainer are set to the clean robot and guide between dust-collecting box gas outflow and the air stream outlet.
Wherein, multiple protrusion tube bodies and be intended to clean surface inclined direction it is identical with conduct direction, opposite or in random number
Direction.
Wherein, which is equipped with multiple first connection units close at the air flow inlet, to the air-flow above the combination
Inlet is equipped with multiple second connection units, and multiple first connection units match with multiple second connection units to be connect.
Wherein, which inhales device with this group and is one of the forming.
For the above-mentioned purpose with effect, the present invention provides a kind of clean robot, includes above-mentioned dust-collecting box.
Wherein, which also includes a roller element, which is set to the clean robot in face of clear
The side of face cleaning is close to the position of the air flow inlet, to stir surface to be cleaned, allow the soil of external environment by dial disturb leave by
Clean surface.
Wherein, which also includes a blowing portion, which is provided close to the position of the air flow inlet, this blows
Wind portion dries toward the direction of the air flow inlet and surface to be cleaned, allows the soil of external environment to be disturbed by group and leaves surface to be cleaned.Its
In, when the clean robot, which operates, advances, those protrude tube body and stir surface to be cleaned, make surface to be cleaned (such as carpet, woollen blanket root
Portion) soil be struck and then leave surface to be cleaned, by clean robot by the gas of external environment from prominent tube body
When second opening is guided into accommodating space, soil enters accommodating space with air-flow, dirty because air flow outlet is equipped with strainer
Dirt can rest on the accommodating space, and the gas for entering the accommodating space will be led by clean robot from the air flow outlet
Deflect from out the shell.
In conclusion the present invention has the advantages that one or more following:
Surface to be cleaned (such as carpet or woollen blanket) can be stirred by dialling suction device, easily soil be made to leave surface to be cleaned.
It dials and inhales device with the protrusion tube body extended towards surface to be cleaned, can protrude into the surface to be cleaned, deeply clean quilt
The root of clean surface.
