Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filter dust removal device for a vacuum cleaner.

Conventional configuration and its problems In conventional vacuum cleaners, a dust collection box is detachably connected to the vacuum cleaner body with a built-in electric blower, and the dust collection box still has a pendulum-like manual rotation mechanism. Some models were equipped with a filter with a moving dust removal lever.

However, since the dust removal lever is configured to be freely rotatable and does not have a fixed position when the operation is stopped, it sometimes hits the air inlet rib of the vacuum cleaner body, causing a situation where the dust collection box cannot be connected. Therefore, the vacuum cleaner body or the dust collection box must be made longer to accommodate the dust removal lever, which has the drawback of increasing the size of the vacuum cleaner.

OBJECTS OF THE INVENTION The present invention solves these conventional drawbacks and is intended to reduce the overall length of a vacuum cleaner.

Structure of the Invention In order to make a vacuum cleaner more compact in the overall length direction, the present invention makes the suction port of the vacuum cleaner body largely enter the filter device, and the dust removal lever for removing dust from the filter is moved away from the suction port. When the main body side and the filter unit are separated from each other, the dust removal lever makes a pendulum movement so that normal dust removal operations can be performed.

Description of examples Examples thereof will be described below based on the accompanying drawings.

In Figs. 1 to 3, 1 is a main body of a vacuum cleaner with a built-in electric blower 2, 3 is an air intake port formed in the main body 1 of a cigarette, and 4 is a plurality of ribs formed on the air intake port 4. Reference numeral 5 denotes a filter device that is detachably provided inside the dust collection boxes 1 and 6. This filter device 6 consists of a filter frame 8 that holds the outer periphery of the filter, which is bent into a wave shape, and a dust removal lever 1o that is rotatably attached to the filter outer frame 8 via a screw 9. It consists of Reference numeral 11 denotes a torsion spring, one end of which is hooked onto the groove 12 of the dust removal lever 10, and the other end inserted into the groove 13 of the filter outer frame 8. Reference numeral 14 indicates a knob formed on the dust removing lever 10, and reference numeral 15 indicates a dust remover formed on the filter 7 side of the dust removing lever 10 corresponding to the knob 14. Reference numeral 16 denotes a gasket attached to the outer periphery of the filter outer frame 8, which provides air tightness with the dust collection box 5. A pre-filter 118 for capturing coarse dust 17 is a buckle that detachably connects the dust collection box 5 and the main body 1.

Reference numeral 19 denotes a handle formed on the dust removal lever 10, which is used when attaching and detaching the filter device 6. 20 is a suction port formed in the dust collection box 5.

In the above configuration, the dust-containing airflow flowing through the suction port 2o is captured by the pre-filter 17 for coarse dust, and the filter 7 for fine dust, and only the clean airflow passes through the suction port 3 and reaches the electric blower 2. It flows. Next, in order to remove the fine dust adhering to the filter 7, unlock the buckle 18 and remove the dust collection box 5 from the main body 1, then hold the knob 14 and move the dust removal lever 1o in a pendulum shape (the third (see figure), the filter 7 is struck by the dust remover 15 and dust is removed from the filter 7. In addition, in FIG. 3, the dust removal lever 10 is always biased to the left by the torsion spring 11, so when it is moved to the right and the hand is removed, the torsion spring 11
It returns strongly with the power of , and can be removed with powerful dust removal. Here, since the dust removal lever 10 is always urged leftward and in a fixed position away from the intake port 3, the ribs 4 are largely inserted into the filter device 6 side, and the device can be made more compact. Also,
The handle 19 used when attaching and detaching the filter device 6 from the dust collection box 5 always returns to normal no matter how much the dust removal lever 1o is operated, so it is always easy to hold.

Effects of the Invention As is clear from the embodiments described above, according to the present invention, by biasing the dust removal lever in a certain direction, the main body can be made more compact and the dust removal effect can be enhanced. It is.
