Hitting-type cleaning system of a filtering member for vacuum cleaner

Abstract

 A hitting-type cleaning system is described, of a filtering member for vacuum cleaner, in particular an ash-cleaner (6), containing at least one filtering member (3), comprising at least one hitting means (1) of said filtering member (3).

Description

[0001] The present invention refers to a hitting-type cleaning system of a filtering member inserted in a vacuum cleaner, and in particular in an ash-cleaner.

[0002] Vacuum cleaners, usually also provided for use as ash-cleaners, are known in the art, and, due to the particular consistency of the sucked ash, are equipped with cleaning systems for the inserted filtering member, such as a self-cleaning system, which uses jets of counter-flowing compressed air; ash-cleaners are also known which are equipped with a cleaning system which performs an axial compression of the above filtering member: an example of such system is disclosed, in particular, in CN-A-2915008.

[0003] Both above arrangements however can brake or degrade the filtering member, strongly reducing the performances of the filtering member and the ash-cleaner in which it is inserted. Moreover, a water-type system is known in the art, which prevents ashes from going out and dusts from being dispersed into the motor, but implies a strong increase of the ash-cleaner weight, since it needs therein a high amount of water.

[0004] Therefore, object of the present invention is solving the above prior art problems, by providing a hitting-type cleaning system of a filtering member for ash-cleaner which guarantees an optimum maintenance of the filtering member, improving its life and its performance quality, and consequently also those of the ash-cleaner in which it is inserted.

[0005] A further object of the present invention is improving the operation of the ash-cleaner by inserting elastic means inside the filtering member, to ensure an optimum hitting.

[0006] The above and other objects and advantages of the invention, as will appear from the following description, are obtained with a hitting-type cleaning system for a filtering member of a ash-cleaner as claimed in Claim 1. Preferred embodiments and non-trivial variations of the present invention are the subject matter of the dependent claims.

[0007] It is intended that all enclosed claims are an integral part of the present description.

[0008] The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:

• Figure 1 is a front sectional view of a preferred embodiment of the hitting-type cleaning system according to the present invention;
• Figures 2 and 3 show a side sectional view of the hitting-type cleaning system according to the present invention, respectively in an operating rest position and in an operating cleaning position;
• Figure 4 shows a side sectional view of a preferred embodiment of the filtering member;
• Figure 5 shows a side sectional view of another alternative embodiment of the hitting-type cleaning system according to the present invention; and
• Figure 6 shows a front sectional view of a further alternative embodiment of the hitting-type cleaning system according to the present invention.

[0009] With reference to the Figures, a preferred embodiment of the present invention is shown and described. It will be immediately obvious that numerous variations and modifications (for example related to shape, sizes, arrangements and parts with equivalent functionality) could be made to what is described, without departing from the scope of the invention as appears from the enclosed claims.

[0010] With reference to the Figures, the hitting-type cleaning system of a filtering member 3 for vacuum cleaner, and in particular for an ash-cleaner 6, according to the present invention is substantially composed of hitting means 1 made of metallic, or plastic material, or other materials, and with a square, oval or other suitable shape, for such filtering member 3, such hitting means 1 being equipped with at least one control member 2 having sizes adapted to be used by a user.

[0011] Preferably, as it is possible to note in Figures 1 to 4, the hitting means 1 of the filtering member 3 are composed of a lever mechanism 7, for example of the first or second order, with manual actuation comprising at least one first end equipped with at least such control member 2, such as for example a handle, a pushbutton, etc., and a second end, opposite to the first end, equipped with a hitting portion of the filtering member 3, such a hitting portion being adapted to externally hit the filtering member 3 in order to externally carry out an hitting and shaking action on the filtering member 3 itself by means of at least one external impact of the hitting portion against the filtering member 3.

[0012] In particular, the lever mechanism 7 is adapted to transmit to the hitting portion a force manually applied onto the control member. With particular reference to Figures 2 and 3, it is possible to note that, starting from an operating rest position of the system according to the present invention, like the one for example shown in particular in Figure 2, the above hitting means 1 are actuated, thereby applying at least one force onto the control member 2, which, transmitted to the hitting portion through the mechanism 7, takes the hitting means 1 to their operating hitting position, like the one for example shown in particular in Figure 3, allowing to hit and shake the filtering member 3 through the simultaneous external impact between the hitting portion and the filtering member 3 themselves, in particular the base or any side portion of such element 3. Such hitting and shaking generates the fall of ashes, trapped in the filtering member 3, into a suitable tank 5 contained in the motored ash-cleaner 6. The filtering member 3, preferably a cloth filter, can be characterised by inserting therein elastic means 4, such as a helical spring, placed perpendicular between the base of the filter framework 8 and the cloth 9 which coats it, optimising the operating efficiency of the hitting means 1.

[0013] Alternatively, as it is possible to note in Figures 5 and 6, the hitting means can comprise at least one fork-type beating element 10, equipped with a double-blade mechanism 11 and operatively connected to at least one control member 12, such fork-type beating element being actuated through manual traction and release of such control member 12, as shown in particular in Figure 5. Such traction movement generates the simultaneous external impact between a hitting portion of one of the two blades of the fork-type beating element 10 and the filtering member 3 and afterwards, the release movement generates the simultaneous impact between the hitting portion of the other blade of the fork-type beating element 10 and such filtering member 3, in particular against the external sides of such element 3. The same fork-type beating element 10 can be equipped with a hinge mechanism 13, as shown for example in Figure 6, and can be actuated by means of a rotation of a related control member 14 suitably connected thereto.

[0014] The whole system can be inserted into the ash-cleaner according to the preferred mode, choosing angle and position.

[0015] The invention has the following advantages:

• it ensures a longer life and efficiency of the filtering member inserted in the ash-cleaner, reducing possible breakage and degrade events of the filtering member itself;
• it allows an easier and more immediate maintenance of the filtering member by a user;
• it guarantees more efficiency of the ash-cleaner wherein the filtering member is inserted: a better cleaning of the filtering member allows a better and longer use of the ash-cleaner, reducing the amount of dust which can damage the internal or external motor;
• it ensures a better cleaning of the environment in which the ash-cleaner is used, since the above hitting system enables ashes, trapped into the filtering member, to fall inside a suitable tank, present in the ash-cleaner. Following a withdrawal of the filtering member from its housing, it guarantees a high reduction of the possible release of ashes in the surrounding environment.
