If be described more specifically the structure of electric dust collector of the present invention, then possess: the suction tool of the dust of the quilt cleaning face on attraction ground etc.; Attraction contains the electric blowing machine from the air of the dust of above-mentioned suction tool; The electric dust collector main body of this electric blowing machine is equipped with in inside; Importing contains the air of the dust that is attracted by electric blowing machine, and the dust separation unit of dirt separation and air; And deposit by this dust separating part from the dust storage part of dust.The dust separation unit constitutes, and has: importing contains the attraction mouth from the air of the dust of suction tool; Contain the gyration airflow ventilating duct that flows through as gyration airflow from the air of this attraction mouthful dust that imports; Form at least a portion of above-mentioned gyration airflow ventilating duct and the dust removal filter of dirt separation and air, when covering the periphery of this dust removal filter, the main air duct that utilization connects to the attraction side of electric blowing machine is from the attraction of the outer circumferential side effect electric blowing machine of dust removal filter.
For gyration airflow occurs, the gyration airflow ventilating duct is made roughly cylindric, preferably cylindric, at the internal face of this gyration airflow ventilating duct and along the circumferential direction and form the attraction mouth of the air-flow rotate.Namely, the attraction direction that attracts mouthful be with the direction of axial quadrature cylindraceous and is tangential direction cylindraceous, so that along the circumferential flow of inner wall surface thereof.What is called is roughly cylindric, contains in the section shape of the face of quadrature axial with it polygon for ellipse, octagonal etc., importantly, as long as generation is along the shape of the circumferential gyration airflow of the internal face of gyration airflow ventilating duct.
In addition, in order in the gyration airflow ventilating duct, gyration airflow to occur, certainly need in the gyration airflow ventilating duct, act on the attraction of electric blowing machine, to produce negative pressure state.Thus, top covering with dust-collecting box is provided with a roughly end of the attraction mouth of gyration airflow ventilation unit cylindraceous, the other end and dust storage part are and are tightly connected, as long as from the attraction of the dust removal filter partial action electric blowing machine that is formed at least the gyration airflow ventilating duct.
As preferred mode, connecting portion or the dust storage part itself of secondary air channel and the gyration airflow ventilating duct of the attraction of effect electric blowing machine can being connected with the dust storage part is connected.Utilize this structure, not only obtain the attraction of dust removal filter part, also can be more near the attraction at dust storage part place, passed through that the dust of dust removal filter is easier to be moved to the dust storage part.
Even an end in secondary air channel is made with the part of dust storage part be connected, attraction side or the other end that the other end is connected to electric blowing machine are connected with a main air duct part that has formed, and all can obtain identical effect.Be preferably made in one of secondary air channel and distolateral the 3rd dust removal filter be installed, do not flow into electric blowing machine one side so that accumulate in the dust of dust storage part.Especially for the attraction that makes electric blowing machine is applied to dust storage part side by secondary air channel, the 3rd dust removal filter preferably adopts screen cloth not allow susceptible to plugging structure.
Therefore, by the 3rd dust removal filter is made the filter that thick dirt is caught usefulness, thereby screen cloth is not easy to stop up, and can stand long use.On the other hand, owing to make thick dirt filter, thin dirt has the possibility that flows into secondary air channel, so if directly enter the attraction side of electric blowing machine, then the durability of electric blowing machine reduces.Thus, in the occasion of the 3rd dust removal filter being made thick dirt filter, thin dirt filter need to be arranged on the upstream by the attraction side of electric blowing machine.
About this thin dirt filter, if will be positioned at the dust removal filter of main air duct as thin dirt filter utilization, as the method that secondary air channel is connected on the main air duct, can be set forth in auxiliary connection air channel on the main air duct of the upstream side that is positioned at the thin dirt filter that consists of dust removal filter.Utilize this connection, can catch thin dirt from secondary air channel with the thin dirt filter that consists of dust removal filter.In addition, utilize this method of attachment, can get rid of thin dirt filter other preparation, the special use of secondary air channel, can improve the maintainability of thin dirt filter.
In addition, in above-mentioned concrete dust catcher, have the effect of utilizing gyration airflow self to purify though be arranged on the dust removal filter of dust separation unit, owing to be the structure that the periphery from dust removal filter attracts, so the screen cloth that can't suppress fully to cause because of dust stops up.For this reason, be provided be used to the dust of removing the dust that has stopped up dust removal filter and remove mechanism, constantly make dust remove mechanism action when the dust catcher entry into service, when running finishes etc., to remove the dust that has stopped up dust removal filter, can not make attraction, attract power to reduce, can use for a long time.
Make dust remove the timing of mechanism's (also being referred to as dedusting mechanism) action, preferably set as follows, namely in the cleaning that reality is used, the screen cloth which kind of degree occurs in dust removal filter in research stops up, and sets with kind, the mode of the dust filter of the structure of designed dust separation unit, use with conforming to.Particularly, the certain hour in when beginning running makes dedusting mechanism work, and the certain hour when running finishes makes dedusting mechanism work, have again when the running beginning and when end both certain hours, make dedusting mechanism work.In order to make dedusting mechanism work with such timing, preferably utilize motor.
For example, utilize microcomputer can realize simply the control that the connection of motor disconnects, as the part of a succession of action of the control part (generally realizing with microcomputer) of the running control of management dust catcher integral body, the Motor Control of dedusting mechanism simply can be packed into.
The control of dedusting mechanism it is also conceivable that and utilizes the electric wire winding mechanism that is contained in electric dust collector inside except using above-mentioned motor.Namely, when the user pulls out the power line that is wound on the electric wire winding mechanism for entry into service, then the electric wire winding part of electric wire winding mechanism utilizes its pullout forces and rotates, and removes mechanism if this revolving force is sent to dust, just then when beginning running dust remove mechanism and move.In addition, usually, in the electric wire winding mechanism, disc spring is housed, if pull out power line, the then electric wire winding part of electric wire winding mechanism rotation, in-built disc spring is rolled.And, for winding cables when finishing running, when pressing the coiling button of electric wire winding mechanism (usually, being configured to press the part of electric dust collector main body), the power of the disc spring that utilization is rolled, make the electric wire winder to the direction rotation of rolled power line with the rolled power line.If the revolving force of general's electric wire winder at this moment is sent to dust and removes mechanism, then when finishing, running can make dust remove mechanism action.
Like this, can suitably select to make dust remove the method for mechanism action, but when at least when the running of electric dust collector begins, when running makes dust remove mechanism action when finishing, the screen cloth that then can eliminate dust removal filter when being each running of cleaning stops up, when each cleaning running, can keep initial attraction, suck the large performance of power.And by adopting above-mentioned dust to remove mechanism in the structure of stopping up at the screen cloth that in the structure of the outer circumferential side of dust removal filter, namely utilizes self catharsis can suppress dust removal filter attraction force acts, thereby this screen cloth can not occur in stopping up for a long time, can not need to safeguard in long-time.In addition, can shorten the actuation time that dust is removed mechanism and be equivalent to screen cloth and do not allow susceptible to plugging actuation time, removing with Motor Drive dust in the structure of mechanism, even make its action when the running of electric dust collector begins, when turning round end, arrangement was not taken time and energy after the user of electric dust collector was transitioned into cleaning action or cleaning, and ease of use is good.
