Description

[Detailed Description of the Invention] The present invention relates to a dust removal device for a vacuum cleaner, and its purpose is to improve usability during garbage disposal.

In recent years, there has been a demand for vacuum cleaners that can be used to dispose of garbage hygienically without soiling hands, and in order to meet this demand, a vacuum cleaner as shown in FIG. 1 has been devised.

That is, a substantially cylindrical primary filter 104 has an opening above a dust collection box 102 which is detachably attached to a vacuum cleaner main body 101, and has an air intake port 103 so as to close this opening.
A filter device consisting of a secondary filter 105 is positioned, and a fine dust receiver 107 having a substantially disc shape and having a fine dust discharge device 106 is arranged in the primary filter 104 directly below the secondary filter 105 so as to be vertically slidable. ing.

The fine dust receptacle 107 is provided with an extrusion shaft 108, and a push button 109 is provided at the tip of the extrusion shaft 108 to move the fine dust receptacle 107 up and down from the outside of the main body 101. When disposing of garbage, the primary filter 104 is moved. The dust collected inside is moved into the dust collection box 102 and compacted, and the dust collection box 102 is removed from the main body 101 and the dust is thrown away.

In this configuration, if you forget to pull up the dust receptacle 107 and use a vacuum cleaner after disposing of the garbage, all the dust will flow into the secondary filter 105 through the intake port 103. At the same time, the suction performance deteriorated early, and at the same time, since the secondary filter 105 was only used to capture fine dust, there was a problem that the filter device could not be used again unless the filter device was disassembled and the adhering dirt was removed. .

To solve this problem, the fine dust receiver 107 can be constantly urged upward with a spring or the like, but the push-out shaft 108
When a spring is attached to the outside of the spring, if air-dite is not sufficient, airflow containing dust will flow and fine dust will adhere to the spring, etc., which will increase sliding resistance and cause the problem of spring squeaking. The assembly of the filter device becomes complicated, which causes problems in terms of assembly cost, and also causes problems in that it becomes difficult for general consumers to disassemble and reassemble the filter device for cleaning.

The present invention solves the above problems, and one embodiment thereof will be described below with reference to the drawings.

After passing through the rope section 20, the air flows into the secondary filter 16 through the outer periphery of the secondary filter 18, and fine dust is removed from the filter medium 1.
Captured by 7.

The air that has passed through the secondary filter 16 is sucked into the electric blower 2 and then exhausted to the outside.

After cleaning is completed and the power cord is wound into the cord winding device 4, when the power cord is pulled out for cleaning again, the cord winding device 4 rotates and transmits rotational force to the dust removal gear 61.

When the dust removal gear 61 rotates, the diaphragm 63 vibrates the filter medium 17 to cause fine dust adhering to the secondary filter 16 to fall.

This fine dust is then stopped by a fine dust receiver 34.

Further, since the transmission pawl 62 of the dust removal gear 61 and the transmission pawl 37 of the fine dust receiving plate 35 are engaged with each other, when the dust removal gear 61 rotates, the pressing plate 30 fixed to the fine dust receiving plate 35 It also rotates.

By rotating the press plate 30 in this way, the fine dust receiver 34
The fine dust accumulated on the top is collected by a fine dust collection plate 44 and introduced into the fine dust intake port 36.

The fine dust reservoir 41 of the fine dust valve 40 collects the fine dust that has flowed in from the fine dust intake port 36, and the press plate 30 further rotates to collect the fine dust.

When the push button 49 is pushed further, the buckle operating part 59 pushes the inclined part 60 and moves the buckle 45 against the force of the buckle spring 46, so the buckle locking part 47 comes off from the buckle hooking part 48 and the lock is released. be done.

When the push button 49 is pressed until it can no longer be pressed and then stopped, the main body lid 5 opens upwardly around the lid shaft 6 due to the biasing force of the lid spring.

Here, as shown in FIG. 3, the dust collection box 24 can be pulled out from the main body, the opening of the dust collection bag 29 tied with a string, etc., and thrown away, and the garbage can be disposed of hygienically without getting the hands dirty.

Further, after release, the push button 49 receives a biasing force from the push button spring 55 interposed between the fixed plate 50 and the spring seat 54 formed integrally with it, so that it always moves upward together with the press plate shaft 42 and the press plate 30. It moves and returns to its original position, thus preventing dust from flowing into the secondary filter 16 side even if the main body lid 5 is closed and dust is sucked again.

Next, when disassembling the filter device, first open the main body lid 5,
Next, press the push button locking part 57 to remove it from the locking hole 58,
The push button 49 and push button spring 55 are separated from the push plate shaft 42.

After that, the press plate shaft 42 and the press plate 30 are moved downward, and then the locking part 22 of the primary filter 18 is removed from the hook hole 21 of the filter outer frame 10 and pulled out downward, and finally the secondary filter 16 is pulled downward. All you have to do is pull it out, and the filter device can be easily disassembled.

Also, for assembly, the above disassembly method may be reversed.

In this way, according to the present invention, the fine dust tray that slides up and down inside the cylindrical primary filter is always urged upward by the spring, so that it is possible to use the vacuum cleaner without forgetting to pull the fine dust tray upward. It can prevent misuse such as driving, and
By installing the spring inside the extrusion shaft through which intake air does not flow, fine dust etc. do not adhere to the spring, and it is possible to prevent an increase in sliding resistance when pushing the extrusion shaft and prevent the squeaking sound of the spring.

In addition, the push button that pushes out the spring and is locked to the end of the shaft and the spring holder that is fixed to the main body are installed between the plates, making it very easy to disassemble and assemble the filter device, making it possible to provide a vacuum cleaner that is easy to use. .
