Strongh vacuum cleaner
Technical field
The present invention relates to domestic electric appliance field, especially, it is related to a kind of dust catcher.
Background technology
Current domestic vacuum cleaners mainly include blower fan and filter core;The front end of dust catcher forms inlet scoop, enters from inlet scoop
Enter the air in dust catcher and pass through the rear arranged after filter core by blower fan to dust catcher.In the process, due to the ventilation of inlet scoop
Area is larger, and air-flow is more uniform so that suction is relatively limited, at the uniform velocity fixed for jam in the larger dust in gap or adhesion
To suction airstream be difficult to be removed.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of Strongh vacuum cleaner, the dust catcher can easily be inhaled
Except stupid dirt, the clean level on sucked object surface can be largely improved.
The technical solution adopted for the present invention to solve the technical problems is:The Strongh vacuum cleaner includes shell, the shell
Interior to be provided with blower fan, the air inlet of the blower fan connects the air intake duct of the case nose, and between air inlet and air intake duct
It is additionally provided with filter core;The air outlet of the blower fan connects the exhaust outlet of the outer casing back;The air intake duct inner route clapboard is divided into phase
Mutual left passage and right passage arranged side by side;Flow direction control mechanism is additionally provided with the dust catcher, the flow direction control mechanism can make institute
State the air inlet of blower fan described in left passage and right passage alternate communication.
Preferably, the flow direction control mechanism includes the left passage, the magnetic valve set respectively in right passage, and
Solenoid valve control module, the solenoid valve control module makes each magnetic valve alternately open and close, to realize that left passage and right passage replace
Connect the air inlet of the blower fan.Further, a position sensor, the position sensor are additionally provided with the dust catcher
When the rate of displacement for sensing dust catcher is less than setting value, each magnetic valve is set alternately to open by the solenoid valve control module
Close, and when the rate of displacement of dust catcher is more than setting value, then make each magnetic valve while keeping it turned on.
Preferably, the flow direction control mechanism includes left passage, the bifurcated of right passage being arranged in the air intake duct
Rotating cylindrical locating, being driven by micromachine, the contoured surface of the rotating cylindrical blocks left passage, right passage, and described
Rotating channel is provided with rotating cylindrical, the left passage, right passage can only pass through the rotating channel and the air intake of the blower fan
Mouth connection;During the rotating cylindrical rotates a circle, the left passage, right passage can be made in turn by the rotating channel
It is connected with air inlet;The preferred structure is simple, and cost is relatively low, and performance is more stable.
The beneficial effects of the present invention are:The Strongh vacuum cleaner operationally, in face of the stupid dirt of more difficult absorption, is inhaled by described
Left passage, the right passage of tracheae are alternately aspirated to it, and now, pumping airflow vibrates back and forth in stupid dirty lateral formation one
Shear force, dragsaw effect is formed, so that stupid dirt is easy to come off so as to object surface, so as to be drawn by air intake duct.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment one of this Strongh vacuum cleaner.
Fig. 2 is the structural representation of the embodiment two of this Strongh vacuum cleaner.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples:
Embodiment one:
In the embodiment one shown in Fig. 1, the Strongh vacuum cleaner includes being provided with blower fan 2, the blower fan in shell 1, the shell 1
2 air inlet connects the air intake duct 11 of the front end of shell 1, and filter core 3 is additionally provided between the air inlet of blower fan 2 and air intake duct 11;
The air outlet of the blower fan 2 connects the exhaust outlet 12 of the rear end of shell 1;The inner route clapboard 111 of air intake duct 11 is divided into mutually
Left passage 11a and right passage 11b arranged side by side;Flow direction control mechanism is additionally provided with the dust catcher, the flow direction control mechanism can
Make the air inlet of blower fan 2 described in the left passage 11a and right passage 11b alternate communications.
In the present embodiment one, the flow direction control mechanism includes what is set respectively in the left passage 11a, right passage 11b
Magnetic valve 41,42, and solenoid valve control module(It is not shown), the solenoid valve control module replaces each magnetic valve 41,42
Open and close, to realize the air inlet of blower fan 2 described in left passage 11a and right passage 11b alternate communications.
Above-mentioned Strongh vacuum cleaner operationally, in face of the stupid dirt of more difficult absorption, by the left passage 11a of the air intake duct 11,
Right passage 11b is alternately aspirated to it, now, the shear force that pumping airflow vibrates back and forth in stupid dirty lateral formation one, such as
Short arc line arrow is illustrated in Fig. 1, forms dragsaw effect, so that stupid dirt is easy to so as to which object surface comes off, so that by air-breathing
Pipe 11 is drawn.
In addition, in embodiment one, a position sensor, the position sensing can also be additionally provided with the dust catcher
Device is suitably positioned close at the external port of air intake duct 11;The position sensor is less than in the rate of displacement for sensing dust catcher
During setting value, each magnetic valve 41,42 is set alternately to open and close by the solenoid valve control module, and when the rate of displacement of dust catcher is big
When setting value, then make each magnetic valve 41,42 while keeping it turned on.So, i.e., for the region for not needing fine dust suction,
The less region of i.e. stupid dirt, dust catcher is generally moved with faster speed, then detects this kind at once by the position sensor
Situation, while opening the left passage 11a and right passage 11b, to improve ventilation, carries out fast dust-absorbing;And when dust catcher is moved
When dynamic speed is slower, dust catcher can be regarded as and carry out smart suction for regional area, at this moment, magnetic valve 41,42 is alternately opened and closed,
Inspiratory airflow can be made more to concentrate and powerful(Such as, left passage 11a or right passages 11b is concentrated on), and form the dragsaw effect,
Then it is more convenient for absorbing local stupid dirt.
Embodiment two:
In the embodiment two shown in Fig. 2, and unlike embodiment one, the flow direction control mechanism includes being arranged at the suction
Endotracheal left passage 11a, right passage 11b it is crotch, by micromachine(It is not shown)The rotating cylindrical 4 of driving, it is described
The contoured surface of rotating cylindrical 4, which is blocked, is provided with rotating channel 40, institute in left passage 11a, right passage 11b, and the rotating cylindrical 4
Stating left passage 11a, right passage 11b can only be connected by the rotating channel 40 with the air inlet of the blower fan 2;In the rotation
During cylinder 4 rotates a circle, the left passage 11a, right passage 11b can be made to enter in turn by the rotating channel 40 with blower fan
Air port is connected;The preferred structure is simple, and cost is relatively low, and performance is more stable.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification for being made, equivalent substitution should be included in the scope of the protection.
