Description
Technical field
The present invention relates to cleaner field, more particularly to a kind of cleaner suction nozzle.
Background technology
Dust catcher is a kind of common health electric equipment, is mainly used in the dedusting of the aspects such as interior, business, industry,
Its primary structure has suction nozzle, flexible pipe, filter plant, laying dust equipment, power-equipment etc., and common vacuum cleaner is by installing
The vacuum pressure that motor inside fuselage sections is produced, after suction is including the air including dust, rubbish, the mistake in fuselage interior
Filter, by after filtering, dust, rubbish precipitate, last air is discharged by exhaust outlet.The dust suction principle of these cleaner suction nozzles
It is to be acted on using negative pressure of vacuum, centered on suction nozzle, surrounding air carries dust, rubbish and flows to the gas that suction nozzle forms certain speed
Stream, and linearly type motion is filtered in subsequently entering filter plant inside the suction nozzle, so as to reach dust removing effects, but dedusting
Efficiency is low.
The content of the invention
In order to solve the above problems, the present invention provides a kind of cleaner suction nozzle that can produce whirlwind, whirlwind is laterally lain
On a surface of an, the efficiency of dust collection of body surface is improved using the agitation of whirlwind solar or lunar halo.
The present invention is achieved by the following technical solutions：A kind of cleaner suction nozzle, including tubular suction nozzle housing, suction nozzle
Ground connection opening and air outlet are offered on housing, ground connection is open in bar shaped along suction nozzle housing genesis analysis, on suction nozzle housing exterior walls
The blast pipe communicated with suction nozzle enclosure interior is provided with, air outlet is opened in side or end face or end face and the side knot of suction nozzle housing
Conjunction portion, when dust catcher works, the air entered from blast pipe or the air entered from blast pipe and ground connection opening will be grounded and be open
The objects such as dust, the rubbish at place are brought into suction nozzle housing and form whirlwind and advance in the shape of a spiral from air outlet discharge.The technical side
The cleaner suction nozzle that case is provided is higher compared to traditional cleaner suction nozzle efficiency of dust collection, and dedusting is more thorough, and simple structure,
Low cost.
Further, blast pipe, in flat, positioned at the side of ground connection opening, is grounded the another of opening to blow ground blast pipe
Side is fixed with ground connection blend stop, and ground connection blend stop close proximity to ground can prevent air-flow from leaking；
Or, blast pipe is common blast pipe, with the relative side in ground connection opening and/or positioned at suction nozzle on suction nozzle housing
It is on the end face of housing and at an acute angle with the angle of the end face.
Further, blast pipe includes blowing ground blast pipe and common blast pipe, blows ground blast pipe, the air-flow of common blast pipe
Direction is consistent with the air direction of rotation entered when being grounded opening as air inlet, so that air-flow is internally formed whirlwind in suction nozzle.
Further, air outlet is opened in one end of suction nozzle housing, and the suction nozzle housing other end is non-air opening end；
Or, air outlet is opened in the side of suction nozzle housing, suction nozzle housing two ends are non-air opening end；
Or, air outlet is opened in the end face and side coupling parts of suction nozzle shell one end, air outlet occupies end face and side simultaneously
The part in face, the other end of suction nozzle housing is non-air opening end.
Further, the whirlwind intensity for increasing the non-air opening end of suction nozzle housing has following technical scheme:
1. ground connection edge of opening is distal to common air intake tube edges to the distance of non-air opening end to the distance of non-air opening end；
2. the non-air opening end of suction nozzle housing is fixed with the cone or conoid being coaxial therewith, cone or class circular cone
The top of body is towards air outlet；
3. the diameter of suction nozzle housing gradually increases from non-air opening end to air outlet；
4. the width of blast pipe is gradually reduced from non-air opening end to air outlet.This in 4 technical scheme can be used alone
Also can be combined and use.
Further, 2 suction nozzle housings are symmetrically fixed together parallel or a suction nozzle housing is folded to form by centre
Side-by-side binary cyclone suction nozzle, it becomes big with extraneous contact area, and suction nozzle can be moved forward and backward carries out dedusting work, user
Just, efficiency of dust collection is higher.
Further, blast pipe is connected to dust catcher exhaust outlet, all or part of sky of dust catcher exhaust outlet by pipeline
Gas enters blast pipe, all or part of air in dust catcher is realized inner loop, because air is filled through the filtering of dust catcher
Dust is there will still likely be after putting filtering, this gas is discharged into air the problem that there will still likely be pollution, so in dust catcher
All or part of air realize inner loop can avoid or reduce reentrainment of dust pollute.Suction nozzle blast pipe and dust catcher air draft
After mouth connection, due to make use of the kinetic energy of dust catcher exhaust outlet air-flow, energy consumption is saved, and for wireless dust collector same
Battery capacity under, to increase wireless dust collector operating time have substantially help.
Further, suction nozzle housing bending take the shape of the letter U, V-arrangement, L-shaped, arc, circle, ellipse, rectangle, triangle, water chestnut
One kind in shape structure, or, the suction nozzle after suction nozzle housing or suction nozzle housing and bending after several suction nozzle housings or bending
Shell combination forms the one kind in V-arrangement, L-shaped, arc, circle, ellipse, rectangle, triangle, rhombus nozzle structure.Bending
Or the suction nozzle after combination becomes big with the contact area in the external world, suction nozzle flexible form is various, and suction nozzle can be removed with multi-direction motion
Dirt works, and efficiency of dust collection is higher.
Further, the two ends for blowing ground blast pipe are provided with baffle plate, prevent from blowing air-flow that ground air inlet enters from its two ends to
Leak.
Further, there is dividing plate in blast pipe, dividing plate, so can be most by blast pipe inside division into multiple air intake holes
Influence of the counteracting housing longitudinal direction suction of limits to blast pipe interior air-flow direction.
Cleaner suction nozzle provided in above-mentioned technical proposal has the advantages that：
1st, there are dust removing effects higher than traditional vacuum principle suction nozzle, the suction size of traditional vacuum suction nozzle mainly takes
Certainly in the height of wind speed in suction nozzle；The whirlwind formed in monomer cyclone suction nozzle, air advances in the shape of a spiral, and its motion can be decomposed
It is to move and moved around axle center direction of rotation along before the straight line of suction nozzle axle center, the motion along axle center straight ahead is equal to vacuum slot
The motion of interior air, along with the rotary motion around axle center, its efficiency of dust collection can be significantly improved；Using whirlwind to being cleaned surface
Cleared up, can be played the same cleaning effect of hairbrush, and be not in that hairbrush is twined and tied up or fabric is damaged by hairbrush
Phenomenon.
2nd, due to the design feature of monomer cyclone suction nozzle, it is connected by pipeline with suction nozzle air inlet in dust catcher exhaust outlet
When, it is possible to achieve circulation of the air inside dust catcher, it is to avoid or reduce reentrainment of dust pollution, the particularly pollution of pm2.5.
3rd, due to that can serve the effect of reducing energy consumption using the airflow kinetic energy of dust catcher exhaust outlet, environmental protection is right
Increase operating time effect is significant in wireless dust collector.
4th, monomer cyclone suction nozzle simple structure of the invention, low cost, efficiency of dust collection is high, combining form is various, applicable surface
Extensively, can be designed as the optimization and upgrading of traditional vacuum suction nozzle.
