Description

Active semi-circulating vacuum cleaner

This creation relates to a vacuum cleaner, especially an active semi-circulating vacuum cleaner that can blow out air to actively lift deep dust and vacuum.

Most of today's vacuum cleaners use motor exhaust to generate internal negative pressure, and then take in external air by negative pressure. During the flow of air, the air flowing through the range is brought into the vacuum cleaner for filtering, but for some small concaves. Holes or slits, because the airflow cannot flow in, it is easy to form a clean corner.

The purpose of the present invention is to provide an active semi-circulating vacuum cleaner, which recovers part of the exhaust gas and enters the dust suction head, actively blows dust and then sucks into the vacuum cleaner for filtering, and comprises: a dust collecting body for taking in air and filtering dust and Exhaust air.

and

a bidirectional exhaust line comprising an exhaust pipe, an exhaust hole, and an adjustable flap; the exhaust pipe directs air into the dust suction head, the exhaust hole discharges air into the atmosphere, and the adjustable flap covers the cover Part of the venting holes to adjust the amount of air discharged into the atmosphere.

and

a suction head comprising a central tube, a peripheral tube surrounding the central tube; The tube is used to blow out air, and the outer tube draws in air.

The active semi-circulating vacuum cleaner provided by the creation is sucked and filtered by the dust collecting body and discharged; the exhaust air is partially discharged into the atmosphere through the two-way exhaust pipe, and partially enters the exhaust pipe to be introduced into the central pipe of the dust collecting head; the dust collecting head The central pipe blows air to raise dust, and then the outer tube absorbs air and dust; and the exhaust hole of the two-way exhaust pipe discharges part of the air into the atmosphere, so that the amount of air blown by the central pipe of the suction head is smaller than that of the peripheral pipe The amount of air inhaled ensures that dust will not be blown out of the suction head, causing secondary pollution; the adjustable flap can adjust the size of the exhaust hole of the two-way exhaust line, and adjust the amount of air discharged into the atmosphere. Blowing cleaning occasions, such as: screen window cleaning, etc., can discharge most of the air, reducing the amount of blowing, to ensure the efficiency of vacuuming.

Figure 1 is a perspective view of a basic embodiment of the present invention.

Figure 2 is a schematic cross-sectional view of the suction head pipe.

Referring to Fig. 1, the air is discharged from the dust collecting main body power section 23, enters the two-way exhaust line 31, part of the air is exhausted by the exhaust hole 311, and the exhaust chute chute 312 and the exhaust chute 313 are used. The effective area of the vent hole 311 is adjusted, and the remaining air enters the suction head intake end 44 by the exhaust pipe 314 and the connecting pipe 51, and is blown out by the air blowing port 431 through the central pipe 43, and the air suction port 421 re-blown air The external atmosphere is sucked together, passes through the suction head peripheral pipe 42 and the suction head suction end 41, enters the dust collecting main body suction end 21, and is filtered by the dust collecting body filtering section 22 to complete the cleaning cycle.

Claims (3)

An active semi-circulating vacuum cleaner comprising: a dust collecting body for absorbing filtration and exhausting gas. A bidirectional exhaust line connecting the exhaust end of the dust collecting body has a venting hole and an exhaust pipe for guiding the air discharged from the dust collecting body to the vent hole and the exhaust pipe, respectively. a suction head having a central tube and a peripheral tube surrounding the central tube, the central tube connecting the exhaust pipe of the two-way exhaust line for blowing air to actively raise dust, and the peripheral tube is connected to the suction end of the dust collecting body, Used to inhale air and dust. The active semi-circulating vacuum cleaner according to Item 1, wherein the exhaust hole of the two-way exhaust pipe is used for discharging air into the atmosphere, and includes a movable flap to block a part of the exhaust hole.
