Description

The internal-circulation type dust catcher

Affiliated technical field

The utility model relates to a kind of vacuum cleaner, especially can effectively reduce the secondary pollution to air.

Background technology

At present, the vacuum cleaner that family uses when the cleaning ground refuse, is the negative-pressure air-flow that utilizes the electric fan in the dust catcher machine to produce, and by inhaling tool, rubbish dust is drawn into dust storage chamber in the machine.Filter is trapped in rubbish dust behind the multiple filtration in the machine just outside the discharge machine, but after machine uses for a long time, machine internal filter surface also will be adsorbed with a lot of trickle dust, can cause the secondary pollution to surrounding air.

Summary of the invention

In order to overcome the secondary pollution that existing dust catcher causes air, the utility model provides a kind of internal-circulation type dust catcher, and this dust catcher can not only remove rubbish, and can effectively reduce second environmental pollution.

The technical scheme that its technical problem that solves the utility model adopts:

Dust catcher is when removing rubbish dust, and the air after the filtration is not directly discharged behind main body, but air-flow is returned to the air entry place again, the air recycling.Establish two air channel interfaces of suction inlet and exhaust outlet in the body, supporting with it hose assembly, straight tube assembly, also built-in air-breathing, the exhaust tow channel gas circulation road of scrubbing brush assembly.Dock with dust storage chamber the inlet scoop of main body of dust collector, negative-pressure air-flow is drawn into dust storage chamber in the machine with rubbish dust, after air filters through filter, dust rubbish is trapped within the dust storage chamber, air-flow after the filtration is then discharged through the air outlet of blower fan afterbody, near wind channel guides to the inlet scoop exhaust ports, the exhaust passage by the flexible pipe seat excrete the place, inlet scoop to scrubbing brush.The flexible pipe that docks with main frame is two-layer air channel structure, and the inboard is an air-suction channel, and the outside is an air exhaust passage.The hose coupling that docks with main frame flexible pipe seat is designed to the dicyclo interface, and butt joint anastomosis seal with elastometic washer prevents that the air between the air channel from leaking.The dust catcher straight tube also is designed to two air channel structures, so that dock with flexible pipe.The butt joint anastomosis is provided with the rubber ring sealing.With the supporting scrubbing brush of this type dust catcher, structurally also different with common scrubbing brush.The universal joint of scrubbing brush is provided with two air channel interfaces, so that dock with straight tube; Air-suction channel porch in the scrubbing brush is provided in a side of the rear of round brush, and negative-pressure air-flow is through the pipeline joint aweather of longshore current behind the round brush; And wind output channel outlet is located at the place ahead of round brush, and exhaust airstream through the leading edge flow of round brush earthward.Round brush in the scrubbing brush is rotating, and direction of rotation is consistent with air flow direction, exhaust and air-breathing in this handing-over circulation.Because inlet scoop and exhaust passage isolate mutually, air stream press design code by way of mobile.In machine, finish suction, cut dirt, filter, discharge four processes.

The beneficial effects of the utility model are when cleaning rubbish, can not cause secondary pollution to surrounding air.

The specific embodiment

Fig. 1 is a main frame outside drawing of the present utility model; Fig. 2 is a flexible pipe outside drawing of the present utility model; Fig. 3 is a straight tube outside drawing of the present utility model; Fig. 4 is a scrubbing brush outside drawing of the present utility model; Fig. 5 is a suction tool appendicle outside drawing of the present utility model; Several parts are connected to form a complete dust catcher.

Among Fig. 6, Fig. 7, electric fan (1) provides negative-pressure air-flow for dust suction, a filter (2) and dust storage chamber (3) are set before the air inlet of electric fan, the band dirt air-flow (25) that enters electric fan is carried out dust to be filtered, air-flow after the filtration (26) is discharged outside the motor through armature from fan outlet, flow to flexible pipe seat (5) through wind channel (4), flow out main frame through the air-out wind passage mouth.

Dirt bag (6) in the wind inlet channel mouth of flexible pipe seat (5) and the dust storage chamber (3) joins.Under the driving of electric fan, band dirt air-flow (25) enters the dirt bag through flexible pipe seat air inlet in machine, and dust is collected in the dirt bag, and then air-flow filters through filter, and the air-flow after the filtration (26) flows into the inlet of blower fan.Under the driving of draught fan impeller, finish suction, filter the air-flow circulation of discharge.The air intake passage mouth (7) of flexible pipe seat (5) is the concentric air channel with air-out passway (8), and the inboard is an air inlet duct, and the outside is the exhaust passage.The butt joint of two passages is along all being provided with rubber seal ring (9), and when hose plug (10) inserted the flexible pipe seat, the butt joint matching surface of two passages had the resilient connection of rubber seal ring, can prevent that the air channel from leaking, and also is convenient to rotate connect.

Fig. 8 is the flexible pipe cutaway view, and hose assembly is by hose plug (10), hose body (11), and flexible pipe handle (12) three parts are formed.Hose plug (10) is a channel structure, is the parts of hose seat, and the centre is double-deck hose body, and central passage is air intake passage (13), and the hose clamp sheaf space is air-out passage (14); Flexible pipe handle (12) is a dust catcher duty functional unit, on operated key (15) is arranged, so that set the running status of dust catcher, the air intake passage (13) of handle (12) and air-out passage (14), divide the both sides up and down that are located at the connection place, the air-out passage is established two outlets, is the product word arrangement with air inlet, and the purpose of She Zhiing is to make butt joint more firm like this.In order to prevent that channel interface from leaking, the joint in the air channel also is provided with rubber ring (9) sealing.

Fig. 9 is the straight tube cutaway view, by interface on the straight tube (16), and straight tube lower interface (17), straight tube body (18), air inlet duct (19), several parts such as exhaust passage (20) are formed; Interface on the straight tube (16) is the plug-in type air channel structure, and when docking with the hose operation handle, to inserting, making separately, air flue communicates two passages respectively.Straight tube lower interface (17) is the embedding plug in construction, and turnover two air channels of scrubbing brush embed with straight tube lower interface (17) and dock, and in order to prevent to leak, the air channel interface is equipped with rubber ring (9).

Figure 10, Figure 11 are the scrubbing brush cutaway view.By housing (21), rotating brush (22) revolves brush motor (23), and scrubbing brush joint (24) etc. are partly formed; Scrubbing brush joint (24) docks with straight tube lower interface (17).

Figure 12 is the brush of dust catcher, is provided with two passages of turnover, and communicates in joint.
