Description

Strong dust collector

Technical Field

The invention relates to the field of household electrical appliances, in particular to a dust collector.

Background

The existing household dust collector mainly comprises a fan and a filter element; the front end of the dust collector forms an air suction opening, and air entering the dust collector from the air suction opening penetrates through the filter element and then is discharged to the rear of the dust collector by the fan. In the process, because the ventilation area of the air suction opening is large, the air flow is uniform, the suction force is limited, and dust blocked in the gap or with large adhesion force is difficult to remove by uniform directional suction air flow.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide a vacuum cleaner which can easily suck and remove stubborn dirt and can largely improve the cleanliness of the surface of an object to be sucked.

The technical scheme adopted by the invention for solving the technical problems is as follows: the powerful dust collector comprises a shell, wherein a fan is arranged in the shell, an air inlet of the fan is communicated with an air suction pipe at the front end of the shell, and a filter element is arranged between the air inlet of the fan and the air suction pipe; the air outlet of the fan is communicated with the air outlet at the rear end of the shell; the air suction pipe is internally divided into a left channel and a right channel which are mutually parallel by a partition plate; and a flow direction control mechanism is also arranged in the dust collector and can enable the left channel and the right channel to be communicated with the air inlet of the fan alternatively.

Preferably, the flow direction control mechanism comprises electromagnetic valves respectively arranged in the left channel and the right channel, and an electromagnetic valve control module, wherein the electromagnetic valve control module enables the electromagnetic valves to be opened and closed alternately, so that the left channel and the right channel are communicated with the air inlet of the fan alternately. Furthermore, a position sensor is arranged in the dust collector, when the position sensor senses that the displacement rate of the dust collector is smaller than a set value, the electromagnetic valves are opened and closed alternately through the electromagnetic valve control module, and when the displacement rate of the dust collector is larger than the set value, the electromagnetic valves are kept opened simultaneously.

Preferably, the flow direction control mechanism comprises a rotating cylinder which is arranged at the branch of the left channel and the right channel in the suction pipe and is driven by a micro motor, the profile surface of the rotating cylinder blocks the left channel and the right channel, a rotating channel is arranged in the rotating cylinder, and the left channel and the right channel can only be communicated with the air inlet of the fan through the rotating channel; in the process that the rotating cylinder rotates for one circle, the left channel and the right channel can be communicated with the air inlet of the fan through the rotating channel in turn; the preferred structure is simple, low cost and more stable performance.

The invention has the beneficial effects that: when the powerful dust collector works, the left channel and the right channel of the air suction pipe alternately suck stubborn dirt which is difficult to suck, and at the moment, the air exhaust flow forms a shear force which vibrates back and forth in the lateral direction of the stubborn dirt to form a sawing effect, so that the stubborn dirt is easy to fall off from the surface of an object and is sucked by the air suction pipe.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

the first embodiment is as follows:

in the first embodiment shown in fig. 1, the powerful vacuum cleaner includes a housing 1, a fan 2 is disposed in the housing 1, an air inlet of the fan 2 is communicated with an air suction pipe 11 at the front end of the housing 1, and a filter element 3 is further disposed between the air inlet of the fan 2 and the air suction pipe 11; an air outlet of the fan 2 is communicated with an air outlet 12 at the rear end of the shell 1; the air suction pipe 11 is internally divided into a left channel 11a and a right channel 11b which are mutually parallel by a partition plate 111; and a flow direction control mechanism is also arranged in the dust collector, and the flow direction control mechanism can enable the left channel 11a and the right channel 11b to be alternately communicated with the air inlet of the fan 2.

In the first embodiment, the flow direction control mechanism includes

electromagnetic valves

41 and 42 respectively disposed in the left channel 11a and the right channel 11b, and an electromagnetic valve control module (not shown), where the electromagnetic valve control module enables the

electromagnetic valves

41 and 42 to be opened and closed alternately, so as to enable the left channel 11a and the right channel 11b to communicate with the air inlet of the fan 2 alternately.

When the powerful dust collector works, the left channel 11a and the right channel 11b of the air suction pipe 11 alternately suck stubborn dirt which is difficult to suck, at the moment, the suction airflow forms a cutting force which vibrates back and forth in the lateral direction of the stubborn dirt, as indicated by short arc arrows in fig. 1, a saw effect is formed, and therefore the stubborn dirt is easy to fall off from the surface of an object and is sucked by the air suction pipe 11.

In addition, in the first embodiment, a position sensor may be further provided in the vacuum cleaner, and the position sensor is suitably arranged near the outer port of the suction pipe 11; when the position sensor senses that the displacement rate of the dust collector is smaller than a set value, the

electromagnetic valves

41 and 42 are opened and closed alternately through the electromagnetic valve control module, and when the displacement rate of the dust collector is larger than the set value, the

electromagnetic valves

41 and 42 are kept opened simultaneously. Thus, for the area where fine dust collection is not needed, that is, the area where dirt is less, the dust collector usually moves at a faster speed, the position sensor instantly detects the condition, and the left channel 11a and the right channel 11b are opened at the same time, so that the ventilation amount is increased, and fast dust collection is performed; when the moving speed of the dust collector is slow, the dust collector can be determined to be sucking precisely aiming at a local area, at the moment, the

electromagnetic valves

41 and 42 are opened and closed alternately, so that the air flow can be concentrated and strong (for example, concentrated on the left channel 11a or the right channel 11 b), the saw effect is formed, and the local stubborn dirt can be sucked and removed conveniently.

Example two:

in the second embodiment shown in fig. 2, unlike the first embodiment, the flow direction control mechanism includes a rotating cylinder 4 provided at a branch of a left passage 11a and a right passage 11b in the suction pipe and driven by a micro motor (not shown), a profile of the rotating cylinder 4 blocks the left passage 11a and the right passage 11b, a rotating passage 40 is provided in the rotating cylinder 4, and the left passage 11a and the right passage 11b can only communicate with the air inlet of the fan 2 through the rotating passage 40; in the process that the rotating cylinder 4 rotates for a circle, the left channel 11a and the right channel 11b can be communicated with the air inlet of the fan through the rotating channel 40 in turn; the preferred structure is simple, low cost and more stable performance.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
