3 is a perspective view of the net filter having a rectifying plate viewed from the inside;

4 is a perspective view of the main body case seen from the front.

The present invention is equipped with a net filter for coarse dust capturing coarse dust, a fine filter for capturing fine dust passing through the net filter, and a cord reel. It is related with the improvement of the cleaner which removes the dust of both filters using the rotation of a cord reel.

Since the filter for sejin captures fine particles of dust, the ventilation surface has a very fine scale compared to the net filter. When fine dust such as dust or fine sand adheres, the fine filter with fine scale is clogged more easily than the net filter. The attached fine dust hardens like cement when it is left for a long time with moisture, and adheres to the fine dust so that the attached fine dust is not easily peeled off from the filter for cleaning.

Particularly, in the wave-like thinning filter, when the particles harden between the convex portions, the attached fine dust hardly falls by merely applying vibration to remove the dust.

Sejin filter thinks it is necessary to remove more dust than net filter.

In addition, since dust is removed using the rotation of the cord reel, this vibration damping force is applied as the load force of the cord reel. Although the cord may be somewhat heavy because the cord is drawn out by hand, the winding of the cord is performed by the return spring, so that the winding rotation of the cord reel does not occur smoothly.

The present invention has been made in view of the above problems, and an object thereof is to provide a cleaning device in which dust of the jinjin filter is removed well and the rotation of the cord reel is performed smoothly.

In other words, the present invention provides vibration damping vibration to the net filter for cleaning and the filter for cleaning using the rotation of the cord reel, and the rotational force in both directions of the winding and rewinding of the cord reel is applied to the filter for cleaning. This is configured to be transmitted, only the rotational force of one direction of the cord reel is configured to be transmitted to the net filter for the dust.

According to this configuration, the dust removal of the fine filter is performed by the rotation of the cord reel before and after using the cleaning machine. This is because it is vibrated immediately after use and does not harden with fine dust attached.

This is because damping is carried out even before use, so it does not harden as it remains attached to the damping after use.

Since dust removal is carried out even before use, it is possible to remove the adhered dust left by the damping after use.

In the vibration filter, only the rotation of the cord reel in one direction is damped, and the rotation of the cord reel is lightened by the damping load of the dust filter.

The cord reel rotates smoothly by the force of the return spring if the vibration damping load of the throttling filter is not applied when the cord is wound.

In this case, dust removal of the dust filter is not performed immediately after using the sweeper, but dust removal is performed by drawing out the cord before use. Since dust attached to the dust filter is not fine dust but coarse dust, even if it is left for a long time from use to use, dust is not sufficiently hardened like fine dust and is well dusted.

On the outer circumference of the drive coupling 57, a tooth portion 62 engaged with the tooth portion 47 of the disc 45 is provided. The rotation of the disc 45 is transmitted to the damping cam 53 via the drive coupling 57, the passive coupling 58, and the support shaft 56.

However, as mentioned above, the rotation transmitted to the damping cam 53 is only one rotation. On the other hand, the damper 43 is rotated even if the disc 45 rotates in either direction.

The net damper 63 is mounted in the center of the net filter 34. The net damper 63 is formed by the leaf spring.

The support part 64 is provided in the center of the net filter 34, and one end of the net damper 63 is being fixed by the screw 65 here. The free end of the net damper 63 is provided to engage the damping cam 53.

The oscillator 66 is provided in the net filter 34 so as to be located near the free end of the net oscillator 63. When the net damper 63 moves as the damping cam 53, the free end of the net damper 63 collides with the oscillator 66 to vibrate the net filter 3 $.

As shown in Figs. 2 and 3, the oscillator 66 is a net filter 34, which is provided at the upper side of the tuning-fork vibration carrier 67, so that the oscillation of the oscillator 66 is a net filter. It is well communicated on the front of 34).

A rectifying plate 68 is provided on the rear surface of the net filter 34, that is, between the net filter 34 and the main filter 39. The rectifying plate 68 is fixed with a screw 65 together with the net damper 63.

The rectifying plate 68 is arranged such that the net filter 34 almost covers the lower half, and a plurality of longitudinal grooves 69 are formed on the lower side. Most of the airflow passing through the net filter 34 flows toward the main filter 39 through the rectifying plate 68.

The inside of the filter main body 33 is divided into the washing chamber 70 on the net filter 34 side and the washing chamber 71 on the main filter 39 side by the rectifying plate 68. In the lower part of the filter main body 33, the fine dust drop hole 72 for the fine dust chamber 70, and the fine dust drop hole 73, such as the fine dust chamber 71, are provided.

Although the above is mainly described in terms of structure with respect to one embodiment of the present invention, the following will mainly be described in terms of operation.

When the electric blower 12 is operated, the airflow containing dust flows into the dust case 2 through the suction hose.

The coarse dust in the airflow is picked up by the net filter 34 and accumulated in the vibration isolation chamber 38. The airflow containing the fine dust passing through the net filter 34 flows through the fine chambers 70 and 71 and the fine dust is picked up by the main filter 39 for cleaning.

Fine dust accumulates in the washing chambers 70 and 71, and the air which has passed through the main filter is discharged out of the main body case 1 via the blower 13 through the hole 46 of the disc 45.

When the cleaning is finished and the cord reel 23 is rotated to wind the power cord, the disc 45 is rotated through the front gear 2, the drive clutch plate 31, and the manual clutch drum 48.

The vibration suppressor 43 rotates by the rotation of the disc 45, and the back surface of the main filter 39 is flipped off the vibration suppressor 43.

As a result, the main filter 39 vibrates, and the fine dust adhering to the main filter 39 shakes off. Fine dust adhering between the convex portions of the main filter 39 is also dropped.

If the dust is left for a long time with the fine dust adhering to the main filter 39, the adhered dust hardens and dedusting becomes bad. However, in the present invention, since the vibration is automatically performed by ending the code after cleaning, the vibration can be satisfactorily achieved.

At the end of the cord, rotation of the disc 45 is transmitted to the drive coupling 57. In this case, the coupling couples 59 and 60 of the couplings 57 and 58 are configured so that the rotation is not performed from the driving coupling 57 to the passive coupling 958. The ring 57 only idles.

Since the vibration damping cam 53 does not rotate unless the manual coupling 58 rotates, the net filter 34 is not damped.

Since the dust is attached to the net filter 34, it is hard to occur such that it hardens like fine dust over time. Even after a while, the dust removal is well done.

Since the vibration of the net filter 34 side is not performed at the end of the cord, the rotational load of the cord reel 23 is lighter.

Usually, since the coiling rotation of the cord of the cord reel 23 is performed by a spring, the rotation of the cord reel 23 becomes smooth as the rotation load becomes lighter. The winding of the cord does not stop in the middle.

The cord reel 23 rotates when the cord is pulled out from the cord reel 23 by hand before the next sweep. As a result, the vibration suppressor 43 rotates in the opposite direction to when the cord is wound. The main filter 39 is vibrated. Since the damping is performed twice after the first damping, the clogging of the main filter 39 is recovered. When the cord is pulled out, the rotation of the cord reel 23 is transmitted to the vibration damping cam 53 via the transmission means such as the disc 45, the drive coupling 57, the passive coupling 58, and the like. The free end of the net damper 63 is bounced by the rotation of the vibration damping cam 53, so that the net damper 63 taps the receiver 66 by the elastic force itself. The shock vibration received by the oscillator 66 is transmitted to the net filter 34 via the vibration carrier 67. As the net filter 34 vibrates, the coarse dust attached to the net filter 34 shakes off.

As described above, the coarse dust of the net filter 34 is performed from the start of cleaning.

However, coarse dust is different from fine dust, so it does not harden over time, so dust removal works well.

Unlike when the cord is wound, when the cord is pulled out, the vibration load of the main filter 39 and the net filter 34 is performed together, so that the rotational load of the cord reel 23 becomes heavier. However, since the cord is pulled out by hand, even if the load becomes heavy, the cord reel 23 does not turn, but vibration can be sufficiently performed.
