Therefore the replacing cost of filter element is corresponding bigger.

Summary of the invention

Therefore the technical problem to be solved in the present invention is in that, it is provided that a kind of can reverse blow air filter, be particularly useful for vacuum cleaner, it is capable of a user just can change filter element and/or cleaning element simply.

Above-mentioned technical problem is by solving according to the air filter of the present invention, wherein, filter element and cleaning element are so firmly attached mutually so that do not destroy and/or damage filter element and/or cleaning element cannot take out cleaning element in the subregion of the clean air cavity limited with filter element. Therefore show that it only can be changed together when filter element is changed in hope merely by the unit destroying filter element and the cleaning element unclamped according to the present invention. It is no longer necessary to by intricately changing filter element from cleaning element separating and filtering element. Therefore the air filter of reverse blow the housed device that always do not need to be cleaned by professional and technical personnel or safeguard can be particularly suitable for according to the present invention, such as vacuum cleaner. Separate from the disconnected position preset on apparatus casing overall for air filter for changing filter element user so that air filter can take out by the unit to include filter element and cleaning element from equipment. Except can changing simply, also getable advantage is in that, the service life of cleaning element can mate with the service life of filter element. Make only just also to be necessary when cleaning element must be changed to change can the air filter of reverse blow, vice versa. It is possible to manufacture at low cost cleaning element and/or filter element in other instances.

Cleaning element is at least partially disposed in the subregion with filter element restriction of clean air cavity in the cell in accordance with the invention. The composition being particularly suitable at this is in that, filter element surrounds cleaning element according to the form of housing at least in part. At this, cleaning element or be fully accommodated in filter element limit area of space in or part stretch out from this area of space, wherein for the present invention in either case all it is essential that must destroy and/or damage filter element and cleaning element one of them just can by both separated from each other. The area of space such as limited with filter element can have hole, and it has ratio and cleaning element takes out the hole cross section that required hole cross section is less from filter element. Here, although cleaning element can move relative to filter element, but can not separate with the latter. Alternatively, filter element can also with the such combined effect of the housing wall defining clean air cavity of apparatus casing so that cleaning element can not from clean air cavity at least in part with filter element limit subregion in take out. In particular, filter element and this housing wall have with porose inner chamber, and this inner chamber is only small, so that cleaning element can not be taken out from this inner chamber.

According to it is proposed that, filter element is substantially designed as tubular or taper. This tubular or taper especially can have filtering material at circumferencial direction and have cladding element at least one end face, and this cladding element is connected with filtering material by least one connecting element. Described connecting element especially can be bonding element. In a kind of design, the area of space with filter element restriction of clean air cavity is tubular/taper, its periphery is advantageously constituted with filtering material completely, and is so closed by one or two end faces so that cleaning element can be accommodated within inseparably. Described tubular/taper, especially the cladding element of Closed End is so constituted, make without destroying/damage and cannot take out cleaning element in the inner chamber of this tubular/taper, this is such as because cladding element is bonded on the end face of described tubular/taper, although described tubular/taper is provided with a perforate for making a subregion of cleaning element pass through, but the hole cross section that this perforate has is less than for taking out the perforate cross section that cleaning element needs. It is configured to cover plate, the end face of its shape closed tube shape/taper accordingly at this cladding element. The equally possible subregion being accomplished that cladding element covers periphery. Can also realizing at this, cladding element fully or at least partially keeps filtering material. Cladding element and filtering material can interconnect by one or more connecting element. Can considering different connecting elements for this connection, it to be adapted at forming the connection not being not to be destroyed between cladding element and filtering material. Such as described connecting element can be bonding element, rivet or like. At this, these connecting elements or be arranged between filtering material and cladding element regularly or brokenly. In particular, filtering material is only connected with cladding element by single local location in the way of point.

In addition specifying, cleaning element is substantially designed as tubular or taper. In particular, this tubular or taper can have purging air access aperture on end face and have at least one purging air tap on the circumferential surface. Same with filter element is that the structure of tubular or taper combines and is capable of coaxially arranged in the inside of filter element of cleaning element. At this, cleaning element can have the matrix of a substantially tubular, this matrix has the nozzle protuberance of the wing from matrix upper process, wherein this nozzle protuberance axially tapering at cleaning element so that cleaning element has conical cross-section in axial cross section. The end region of nozzle protuberance is configured to one or more purging air tap. To this alternatively, matrix self can be designed as taper so that be similarly obtained the cross section of the taper of the cleaning element with nozzle protuberance. When reverse blow can the air filter of reverse blow purging air flow through the purging air access aperture on the end face being arranged in cleaning element, penetrate cleaning element and finally by arranging that purging air tap on the circumferential surface leaves. At this advantageously, the purging air access aperture being arranged on the end face of cleaning element is corresponding with the perforate in the cladding element being arranged in filter element so that purging air can arrive cleaning element by cladding element. The filtering material of filter element is designed as ventilative so that the purging air flowed out from cleaning element by purging air tap is perforated through filtering material and plays the effect of clean filtering material at this. Such as filtering material can be microfibre hair or similar gas permeable material.

Advantageously the purging air access aperture of cleaning element has fluid section, and described fluid section is more than the summation of the fluid section of purging air tap or the fluid section of purging air tap. In cleaning element, nozzle act is realized so that the purging air flowed by cleaning element is being accelerated on the direction of one or more purging air tap from purging air access aperture by this design. This is due to the reduction of fluid section, this realizes in the following way, namely the fluid section of purging air access aperture unique purging air tap arranged more than on cleaning element fluid section or when arranging multiple purging air tap more than the summation of all fluid sections of purging air tap.

Thus, the purging air flowed out from one or more purging air tap produces torque, and this torque makes the rotary air nozzle rotation being pivotably supported. It is therefore advantageous that cleaning element rotates at filter element interior, wherein, the inwall of filter element is cleaned on whole circumference. By this design, even if when rotary air nozzle does not have purging air tap on its whole circumference, cleaning also is able to cover the whole circumference of inwall. Advantageously, purging air tap is slot-shaped being axially designed as of cleaning element so that it is at the inwall that filter element is axially completely covered.

In addition the present invention is directed to a kind of can the air filter of reverse blow, especially the above-mentioned type can the air filter of reverse blow, described air filter has clean air cavity from the filter element being separated out with ash air chamber, filter run time until filtering air from ash air chamber flow through to the direction of clean air cavity described filter element and when cleaning is run purging air flow through described filter element from clean air cavity to the direction with ash air chamber, wherein, for clean air cavity distribution be arranged at least partially clean air cavity with filter element limit subregion in cleaning element, for reverse blow filter element, wherein, cleaning element design is used for, remove at filter element towards the dust gathered on the side with ash air chamber, wherein, in cleaning is run, cleaning element can vibrate. in particular, cleaning element can be rotatably supported at cleaned air intracavity around rotation axis, and wherein, cleaning element has degree of unbalancedness with reference to this rotation axis. by this design, the cleaning effect additionally realized as filter element being carried out supplementing of perfusion by purging air is in that, the degree of unbalancedness formed on cleaning element causes vibration during reverse blow process. the vibration caused by the degree of unbalancedness of cleaning element is flowed by air and/or passes to filter element by cleaning element with contacting of filter element so that the dust that filter element shake and a part accumulate on the outer wall of filter element is eliminated. the cleaning efficiency improved so totally is realized by cleaning element.

According to it is proposed that, the degree of unbalancedness of cleaning element is determined by the alteration of form in direction of rotation of cleaning element. In particular, this alteration of form can be the change of the fluid section of the purging air tap being arranged on cleaning element continuously in direction of rotation. It is important in this that, the rotation axis of cleaning element is inconsistent with principal axis of inertia line. This feature can be realized by the measure of the position of multiple mobile principal axis of inertia line. Except passing through the alteration of form of the special arrangement of the purging air tap on cleaning element, equally it is also contemplated that other so changes the measure of the Mass Distribution in the material of cleaning element so that the quality that the half cycle of such as cleaning element has is different from the quality of the second half cycle. This can pass through to select different materials, different material thicknesses or similar realization.

This air filter 2 of reverse blow can have filter element 3 and cleaning element 6. At this, filter element 3 is substantially designed as tubular, and cleaning element 6 is also such, and wherein, filter element 3 has filtering material in circumferential direction and is respectively provided with cladding element 12 on two end faces. Cleaning element 6 is coaxially arranged in filter element 3. Filter element 3 will be arranged in separating with ash air chamber 5 between filter element 3 and apparatus casing 11 with the clean air cavity 4 in the inner chamber being arranged in filter element 3.

Cleaning element 6 has purging air access aperture 7 on end face (top in Fig. 1), and purging air can pass through purging air access aperture 7 and enter in cleaning element 6. Arranging purging air tap 8 (figure 2 illustrates) on the periphery of cleaning element 6, purging air can pass through purging air tap 8 and leave cleaning element 6. It is respectively arranged connecting element 13 between filtering material and the cladding element 12 of side arranged on the periphery of the filter element 3 of tubular. Connecting element 13 is such as designed as the bonding region of annular, and described bonding region is bonded in cladding element 12 on filter element 3. Can air filter 2 entirety of reverse blow be maintained in apparatus casing 11 by (above) cladding element 12. Such as, cladding element 12 can be bearing in (not shown) in design projection on apparatus casing 11.

Cleaning element 6 is arranged substantially in filter element 3, wherein, has the cladding element 12 of subregion traverse filter element 3 on the top of purging air access aperture 7 thus outwards deriving. Cleaning element 6 can be rotated to support in filter element 3 by supporting arrangement 9. At this, this supporting arrangement 9 is such as designed as the top on the bottom surface of cleaning element 6.

The filtering material of filter element 3 is ventilative material, such as synthetic felt, and the dust/foul leached from air remains adhered on described filtering material.

Fig. 2 illustrates can the top view of air filter 2 of reverse blow. Apparatus casing 11 or filter element 3 and cleaning element 6 are all disposed concentrically upon, wherein, be designed as the cladding element 12 of annular guarantee can concentric in apparatus casing 11 of the air filter 2 of reverse blow, and the purging air access aperture 7 of the flange shape restriction of cleaning element 6 guarantees concentric in filter element 3 of cleaning element 6. Equally, this guarantees by being arranged in the supporting arrangement 9 on the bottom surface of cleaning element 6 and the supporting arrangement 9 that is arranged on cladding element 12 with one heart.

According to Fig. 2, cleaning element 6 is designed as rotary air nozzle, at this, described rotary air nozzle has the purging air tap 8 outside two sensings, purging air tap 8 designs and is arranged as so that from cleaning element 6 flow out purging air make rotary air nozzle rotate thus on whole circumference the inner surface of cleaning filter elements 3. Axially purging air tap 8 at air filter 2 (not shown) is designed as slot-shaped so that purging air tap 8 is fully extended on the axial length of filter element 3. The purging air access aperture 7 of cleaning element 6 is passed the cladding element 12 of filter element 3 and such as can be connected on the air duct being equipped with fan of vacuum cleaner.

Fig. 3 and Fig. 4 illustrate can the different embodiment of air filter 2 of reverse blow, be distinctive in that filter element 3 and the separability of cleaning element 6.

Root according to Fig. 3, the air filter 2 of reverse blow can be designed as the inseparable unit including cleaning element 6 and filter element 3. As shown in FIG. 1, the filtering material of filter element 3 is firmly connected with cladding element 12 by connecting element 13 so that does not destroy air filter 2 and cannot take out the cleaning element 6 in the inner chamber being arranged in filter element 3. If user wishes to take out from apparatus casing 11, air filter 2 it is necessary to be replaced by by this air filter 2 includes filter element 3 and cleaning element 6 does not destroy the unit that cannot separate.

According to this design, cleaning element 6 is inserted in filter element 3, wherein, must also take out filter element 3 when being intended merely to change cleaning element 6, in order to enable users to touch cleaning element 6 from apparatus casing 11 simultaneously.

Fig. 5 to Fig. 7 illustrates the different embodiment of cleaning element 6.

Fig. 5 illustrates the first embodiment, and wherein, cleaning element 6 has a purging air access aperture 7 and two slot-shaped purging air taps 8. Purging air tap 8 designs in the stub area of the nozzle protuberance of wing. Total fluid section that two purging air taps 8 have is less than the fluid section of air access holes 7. Flow into the purging air of cleaning element 6 from there through air access holes 7 accelerate in cleaning element 6 and leave cleaning element 6 with the flowing velocity after improving by purging air tap 8. Shown in the slot-shaped purging air tap 8 that designs in the axial direction be only the example of the present invention. Alternatively, it is also possible to specify multiple purging air tap 8 being disposed adjacent in the axial direction or replace slot-shaped purging air tap 8 regulation ellipse ground, circularly or the design of other shaping.

In the not revolvable situation of cleaning nozzle, it is proposed that purging air tap 8 as much as possible is set on the periphery of cleaning element 6. As long as cleaning element 6 relates to the nozzle (rotary air nozzle) of rotation herein, avoid the need for designing purging air tap 8 with covering at the periphery upper surface of cleaning element 6. But suggestion, design at least one purging air tap 8 on the whole axial length of cleaning element 6 so that the purging air of outflow can flow through the whole inner surface of filter element 3. Rotating purging air tap 8 have outflow plane for ordering about cleaning element 6, the plane normal of this outflow plane is not radially (rotation axis from cleaning element 6). Contrary air flows out the angle that direction has to the radial direction of rotary air nozzle and is not equal to 0 �� so that make cleaning element 6 rotate by air blast.

The embodiment of the cleaning element 6 shown in Fig. 6 includes the cleaning element 6 degree of unbalancedness with reference to rotation axis. This degree of unbalancedness realizes in the following way, namely designs on the periphery of cleaning element 6 purging air tap 8 and has the fluid section different with other purging air tap 8. At purging air tap 8 above, there is the area more significantly larger than the purging air tap 8 (and two other purging air tap 8) illustrated on the back side of cleaning element 6 in the drawings shown in figure. The quality being made two half cycles of cleaning element 6 by this design is different, wherein, the first of cleaning element, first half have than the second of cleaning element 6, quality that latter half is less. Because the principal axis of inertia line of cleaning element 6 is no longer identical with the rotation axis of cleaning element 6 in this design, so cleaning element 6 vibration when being rotatable about axis and rotating. Because cleaning element 6 is bearing on filter element 3 in air filter 2, so the vibration of cleaning element 6 is also passed on filter element 3, accumulate dust at filter element 3 towards the outside with ash air chamber 5. From filtering material, at least some of of the amount of dust gathered is removed by this vibrational energy. In conjunction with purging air, the perfusion of filtering material is capable of the cleaning action optimized.

Cleaning element 6 shown in Fig. 7 has functional element 10 on its outer circumference surface. This functional element 10 of embodiment is designed as bristle elements as illustrated, and described bristle elements is radially erecting from cleaning element 6. Alternatively, functional element 10 can also be fine, soft fur, yarn fabric bar, projection or like. Functional element 10 is arranged on cleaning element 6 so that when in conjunction with the filter element 3 of air filter 2, functional element 10 is formed with the inner surface of filter element 3 and contacts. The inner surface sweeping filter element 3 is dragged so that filtering material is at least partly in vibration and makes the dust gathered drop at cleaning element 6 functional element 10 when the internal rotating of filter element 3. Functional element 10 can be designed as yarn fabric bar in other embodiments, and described yarn fabric bar passes through the rotation of cleaning element 6 that is centrifugal force flatly points to and only at this moment just contacts with filter element 3 formation.

Last Fig. 8 and Fig. 9 illustrates that the air filter 2 according to the present invention is filtering run duration (Fig. 8) and the key diagram in cleaning run duration (Fig. 9).

As shown in FIG. 8, (in figure left side) in apparatus casing 11 is flowed into the air of dust. Apparatus casing 11 is such as the subregion of shell of the dust collector, and wherein, the air with dust flows from the suction nozzle with earth surface to drawing fan. Should enter with the filter element 3 in ash air chamber 5 and in the air filter 2 then penetrating in load facility housing 11 in apparatus casing 11 with the air of dust. Filter element 3 is designed as tubular, and at this, the air with dust flows through filtering material on the whole periphery of this tubular. When perfusion, the air with dust is cleaned, wherein, is included in the dust in the air with dust or foul accumulates on the sensing of filter element 3 side with ash air chamber 5. The air arrived in the inner chamber of filter element 3 is thus cleaned of dust/foul. Thus forming clean air cavity 4 in filter element 3, clean air cavity 4 has fluidly connecting of the fan to such as described equipment (vacuum cleaner).

The cleaning run duration of the air filter 2 that figure 9 illustrates, air (ambient air of equipment) is flowing through filter element 3 with aforesaid filtration in operation opposite direction. At this, air arrives the inner chamber interior (from right side in figure) of cleaning element 6 by purging air access aperture 7. Advantageously, cleaning element 6 is designed as rotary air nozzle, and its purging air tap 8 is towards being different from air discharge direction radially. Rotary air nozzle is thus made to rotate so that purging air flows through the inner surface of filter element 3 on whole periphery. This purging air is radially from inside to outside penetrating the filtering material of filter element 3, and the dust thus gathered on the outer wall of filter element 3 is washed out and is such as arrived in dust receptacle by the hole in apparatus casing 11 with ash air chamber 5 and design. Advantageously cleaning element 6 can have degree of unbalancedness extraly so that cleaning element 6 vibrates during it rotates and the filter element 3 with dust is passed in consequent vibration. At least some of dust is removed from the outside of filter element 3, overall raising filtration by vibrating.
