The dust catcher of a kind of features simple structure, reliability and durability

Technical field:

The utility model relates to family expenses and commercial vacuum cleaner, particularly combined small vertical type dust collector.

Background technology:

Vacuum cleaner is power source with the vacuum blower, can produce certain vacuum, air quantity, through linking with various custom-designed scrubbing brushes, hairbrush, suction inlet, can effectively remove the various dusts of home environment.Dust catcher came out nearly 100 years, and in countries such as Europe, America, dust catcher is as the special-purpose burnisher of removal dust, and is essential in family life, and its, sales volume was above 1.3 hundred million in market year.

The main flow form of existing dust catcher is horizontal dust collector (seeing accompanying drawing); Comprising one, contain can vacuum blower fan, connects with scrubbing brush through assemblies such as flexible pipe, long pipes, in operation; Main frame is placed on the ground and can be dragged, and cleanup crew's hand hose line assembly cleans ground.But the dust catcher of this form has two defectives clearly: the one, and parts are too many, the tired lock of operation, and need bigger storage area; The 2nd, receive the obstruction of household goods in the operation, drag inconvenience in the use.And blower fan is vacuum power resources, and blower fan is placed in the head; Head connects through flexible pipe with scrubbing brush; Long distance is arranged, 2.5～3 meters distance is generally arranged, air communication is crossed scrubbing brush, adapter, flexible pipe entering head; The long energy that causes of pipeline has very big loss, has caused waste of electric energy.And in actual fabrication, more fit clearance being arranged between each parts, in long-term the use, gas leakage is to a certain degree caused in these gaps, has strengthened loss, causes dust catcher air quantity decline in use.When cleaning floor, this loss clearly to show as scrubbing brush air inlet place wind speed low, cleaning effect is bad.In addition, horizontal machine comprises parts such as head, flexible pipe, adapter, scrubbing brush, is placed on the very big space of indoor needs, brings inconvenience.

The another kind of common kenel of existing dust catcher is to make an integral body to head and scrubbing brush, common vertical machine (seeing accompanying drawing 2) in Here it is the market, and vertical machine is made an integral body to blower fan, scrubbing brush; In use, promote complete machine, just can accomplish cleaning ground; Vertical type dust collector is stronger than horizontal dust collector associative perception; And can in scrubbing brush, increase a motor-driven round brush, nuclear reason carpet is specially adapted to floor cleaning.This type mainly uses at American market, is specially adapted to large-area clear long-pending.The main benefit of this type is convenient cleaning to ground; But the cleaning for metope, sofa, windowsill, desktop, electrical equipment etc. is very inconvenient; In order to remedy this defective, generally be on head, to increase a bypass flexible pipe, be used to connect various hairbrush commonly used, suction inlet.Therefore, the volume of this type dust catcher is very big, and cost is high, uses as high-end type always.

Along with the development of motor technology, under the prerequisite that keeps air quantity and vacuum, that the motor of dust catcher can be done is littler, weight is lighter; Since 21 century; A kind of brand-new hand held cleaner becomes the new lover in market, and sales volume constantly increases, but hand held cleaner is because volume is too little; The finite capacity of dust is not suitable for the cleaning to floor-dust always.With the hand held cleaner is the combined type dust catcher on basis, though can carry out floor cleaning, floor cleaning is not a major function.The function that how to keep the big dust capacity of horizontal (vertical) dust catcher, ground convenient for cleaning; The characteristics that can have simultaneously simple in structure, the handled easily of hand held cleaner again; Article such as metope convenient for cleaning, sofa, windowsill, desktop, electrical equipment; Become the research and development emphasis of each dust catcher company, the proportion of this type of combined type dust catcher in market was enlarging gradually in recent years.The compound mode of this type combined type dust catcher (seeing accompanying drawing 3), the one, as hand-held set, when cleaning metope, sofa, windowsill, desktop, electrical equipment, directly use hand held cleaner.The 2nd, when cleaning floor, hand held cleaner is put into complete machine or connected push rod, as vertical type dust collector ground is cleaned.An obvious defects---receive the restriction in body space, the dust capacity is little in this combined type dust catcher existence, and when cleaning floor, the dust on ground is more, and obstruction air channel that can be very fast causes suction to descend rapidly.Therefore, this combined type dust catcher exists not enough on the floor cleaning function, can't strive unexpectedly with the horizontal dust collector or the vertical type dust collector of main flow, in actual use, can only replenishing as the main flow dust catcher.
