It should be noted that the rotating or drawing mentioned above may be both achieved by user's manual operation and achieved automatically by setting a corresponding motor.

FIG.7shows a sectional view of a filter cleaning system according to the present disclosure;FIG.8is a schematic diagram showing the structure of a filter according to the present disclosure; andFIG.9is a sectional view showing the structure of the filter according to the present disclosure. As shown inFIGS.7-9, the present disclosure also provides a filter cleaning system; the filter cleaning system includes a hollow filter300and a filter cleaning apparatus, one end of the filter300is provided with an opening301; the filter cleaning apparatus includes a shielding body100, and at least one cleaning strip is arranged on the inner wall of the shielding body100; the shielding body100is provided with a dust suction connector200, one end of the dust suction connector200is connected with dust suction apparatus, and the other end of the dust suction connector200is in communicated with a cavity in the shielding body100.

An air inlet151′ is opened on the side end of the shielding body100, and the filter300is assembled in the shielding body100in the filter cleaning apparatus when the filter300needs to be cleaned. Specifically, one end, having the opening301, of the filter300is positioned at the same side as the side end, having the air inlet151′, of the shielding body100, i.e., the opening301is positioned adjacent to the air inlet151′, so that at least partial airflow enters into the filter cleaning apparatus from the air inlet151′ flows through the opening301, and then flows into the inside of the filter300when the filter cleaning system works.

To sum up, in the present disclosure, by arranging a dust collection connector on the filter cleaning apparatus, when the filter is cleaned, the dirt may be sucked into the dust collection apparatus in real time by the dust collection connector. Therefore, the filter may be cleaned without water washing and air drying. Moreover, the filter cleaning apparatus does not need to be cleaned regularly, and it is easy to operate, thus optimizing user experience.

FIG.10shows an explosive view of the structure of a filter cleaning apparatus according to the present disclosure; andFIG.11is a schematic diagram showing the structure of filter cleaning apparatus according to the present disclosure. As shown inFIG.10andFIG.11, the present disclosure also provides another filter cleaning apparatus, including a shielding body100and a covering body400; at least one cleaning strip is arranged on an inner wall of the shielding body100, and the cleaning strip is used for cleaning the filter, preferably, the cleaning strip is a wool top or rubber strip; the covering body400is arranged on a side end of the shielding body100.

In order to facilitate accommodation and filter cleaning, the shielding body100of the present disclosure is a hollow cylinder. The shielding body100may be formed by splicing a plurality of components; preferably, the shielding body100is formed integrally. At this time, the filter is mounted from a side end of the shielding body100to complete the assembly of the filter and the filter cleaning apparatus.

The cleaning strip may be fixed on the inner wall of the shielding body100, for example, it may be pasted by adhesive or by directly machined into an integral structure. To facilitate the maintenance and cleaning of the cleaning strip, the cleaning strip is detachably fixed on the inner wall of the shielding body100. Specifically, a clamping groove (not shown in the drawings) is arranged on the inner wall of the shielding body100, and the clamping groove is correspondingly arranged to the tail end of the cleaning strip; the tail end of the cleaning strip is inserted into the clamping groove to achieve the assembly/disassembly thereof.

The covering body400includes a connecting portion410and a fixing portion420, and the connecting portion410is rotatably sleeved on a side end of the shielding body100and is used for connecting the fixing portion420on the shielding body100; a buckling portion421is arranged on a position, towards the shielding body100, of the fixing portion420. Specifically, the buckling portion421may be a lug boss or a groove, but is not limited thereto as long as its shape can be buckled with the filter accordingly.

Specifically, the connecting portion410is ring-shaped correspondingly when the shielding body100is hollow cylinder. To restrain the rotation track of the connecting portion410on the side end of the shielding body100, thus making the covering body400rotating stably and ensuring its cleaning efficiency thereby, an annular groove102is arranged on the outer wall of the side end of the shielding body100; the connecting portion410is provided with a limiting block411, and the limiting block411is correspondingly arranged to the annular groove102. The limiting block411is clamped into the annular groove102after the connecting portion410is assembled on the side end of the shielding body100; the limiting block411is restrained by the annular groove102when a user rotates the connecting portion410, thus making the connecting portion410rotating stably.

In general, for the convenience of assembly, the side end face of the existing filter on the market is non-planar and has a concave-convex structure, e.g., the side end face is provided with a positioning hole or positioning column. As the buckling portion421on the fixing portion420is arranged towards the inside of the shielding body100, and when the connecting portion410rotates, the buckling portion421contacts the corresponding concave-convex structure on the filter during the rotating process, thus driving the filter to rotate; the filter is scraped by the cleaning strip when rotating, and dirt attached on the filter is scraped into the filter cleaning apparatus.

For the convenience of manufacture, the buckling portion421may be integrally formed with the fixing portion420.

In order to accommodate different kinds of filters, the buckling portion421may be separately formed and detachably fixed on the fixing portion420. Specifically, a plurality of fixing grooves (not shown in the drawings) are arranged on a position, towards the inside of the shielding body100, of the fixing portion420, and the number and specific position of the fixing grooves on the fixing portion420are not limited in the present disclosure. For example, the number of the fixing grooves may be four, and these are annularly distributed on the inner wall of the fixing portion420. In the present disclosure, the buckling portions421may correspond to the fixing grooves one by one, namely, each fixing groove is provided with a buckling portion421. The number of the buckling portions421may be more or less than that of the fixing grooves, for example, the number of the buckling portions421is two when there are four fixing grooves and the position of the buckling portions may be chosen by the user according to the structure of the filter freely; additionally, in actual operation, the buckling portions421in different height may be replaced according to the buckling conditions between the buckling portion421and the filter, so that the fixing portions420of the present disclosure can be adapted to more kinds of filters.

In the present embodiment, the number of the buckling portions421is four, and these are annularly distributed on the fixing portion420.

The connecting portion410and the fixing portion420may be integrally formed or formed by assembly.

When the connection portion410and the fixing portion420are formed integrally, if the filter is to be cleaned, the covering body400needs to be removed from the side end of the shielding body100, then the filter is mounted, afterwards, the covering body400is assembled on the side end of the shielding body100, so that the limiting block411on the connecting portion410of the covering body400is buckled into the annular groove102on the outer wall of the side end of the shielding body100, and finally the filter is cleaned by rotating the covering body400.

When the connecting portion410and the fixing portion420are formed by assembly, as shown inFIG.11, the connecting portion410and the fixing portion420may be coupled together by the articulated shaft500in a counter-rotating manner, and at this time, the filter can be mounted by opening the fixing portion420only without removing the covering body400. Specifically, the user may open the fixing portion by making the fixing portion420rotating with the articulated shaft500.

In order to avoid the accumulation of dirt in the filter cleaning apparatus, a dust suction connector200is arranged on the shielding body100, one end of the dust suction connector200is communicated with the dust collection apparatus, the other end of the dust suction connector200is communicated with a cavity in the shielding body100; and dirt in the shielding body100is sucked into the dust connection apparatus by the dust collection connector200under the suction force provided by the dust collection apparatus, so that the dust on the filter can be immediately sucked away after scraped by the cleaning strip, thus achieving the cleaning of the shielding body100while cleaning the filter.

To improve the airflow velocity of the shielding body100and effectively suck out dirt, when the dust collection connector200is connected with the dust collection apparatus, a blocking portion150is arranged on a side end, away from the covering body400, of the shielding body100, and the blocking portion150is provided with one or more openings151; when the dust collection apparatus works, airflow enters from the openings, and flows through the filter assembled in the shielding body100, then flows out of the dust collection connector200. The configuration of the blocking portion150reduces the inlet air area of the side end of the shielding body100, which may effectively improve the speed of the inlet air in case of constant power, that is to say, the suction force can be effectively enhanced, thus sucking away the dirt scraped during cleaning process by the dust collection apparatus more efficiently.

The blocking portion150may be integrally formed with the shielding body100, or may be fixed onto the side end of the shielding body100after formed separately.

The filter cleaning apparatus of the present disclosure will be described with reference to detailed embodiments hereafter.
