Description

[Detailed explanation of the idea] The present invention relates to a dust collector for a vacuum cleaner.

In conventional vacuum cleaners, there is generally no partition wall on the bottom of the pre-filter that covers the main filter that captures fine dust, so when the main filter is removed, the fine dust collects in the fine dust chamber of the crotch box. It had become.

Therefore, when the filter is removed when disposing of garbage, fine dust adhering to the main filter and pre-filter will be removed from the pre-filter.
Sometimes it would fall from the bottom and stain floors and clothing.

The present invention eliminates the above-mentioned conventional drawbacks and provides a dust collector that can perform garbage disposal work in a sanitary manner.One embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is the vacuum cleaner main body (hereinafter referred to as the main body);
2 is an electric blower built into the main body 1; 3 is a rear wheel; 4 is a rear wheel;
5 is a front wheel, 5 is a seat box connected to the main body 1, 5' is a connection port for connecting a hose (not shown), 6 is a handle for carrying the seat box 5, and 7 is the main body 1 and the seat box 5. Buckle for attaching and detaching, 8
A support frame supports a tightening rubber 9 for tightening the crotch seat box 5 and the main body 1, and a main filter 10 is attached to this support frame 8.

11 is a diaphragm inserted into the wall of the main filter 10;
Reference numeral 12 denotes a dust remover that repels one end of the diaphragm 11, and is attached to a rotating shaft 13 rotatably supported by a bearing 8' formed in the support frame 8.

A handle 14 is attached to the other end of the rotating shaft 13, and has a knob 15 at the tip.

Reference numeral 16 denotes a pre-filter that covers the main filter 10 and is equipped with a net 16' for capturing coarse dust.The lower surface is made impermeable, and a fine dust outlet 17 is provided at the lower front of the filter. It is provided with a lid body 19 that is biased by a spring body 18 so as to be openable and closable.

20 is a protruding rib provided on the lower surface of the seat box 5 for pushing open the lid 19 against the spring body 18; 21 is a partition wall provided horizontally above the rib 20; A fine dust chamber 22 is formed with the wall surface of the seat box 5.

In the above configuration, from the dust sucked in through the connection port 5', coarse dust is separated by the pre-filter 16, and fine dust is further separated by the main filter 10, and clean air containing no dust is delivered to the electric blower 2 side. be sent away.

The coarse dust separated by the pre-filter 16 is collected in the coarse dust storage space above the partition wall 21 of the crotch box 5, and the fine dust separated by the main filter 10 is collected by rotating the bundle 14. The dust removal body 12 provided at the tip of the dust removal body 13 strikes the diaphragm 11, detaches it from the main filter 10, and deposits it on the lower surface of the pre-filter 16.

In order to place the connection port 5' of the crotch box 5 downward when disposing of garbage, a dust outlet 17 is provided at the front lower part of the pre-filter 16.
As a result, the accumulated fine dust moves to the fine dust chamber 22 of the seat box 5.

Next, when the filter is taken out from the seat box 5, the lid body 19 is separated from the protruding rib 20 of the seat box 5, and the spring body 1
8 blocks the dust outlet 17, so when the filter is removed from the crotch box 5, the pre-filter 16 is closed.
Even if fine dust remains inside, it will not fall out because the lid 19 is closed.

As described above, according to the present invention, the lower surface of the pre-filter is made impermeable, a fine dust outlet is provided at the lower front surface, a lid body is provided to close this outlet with a spring body, and the rib of the crotch box is Since the lid is pushed open at the time of garbage disposal, the lid is closed when disposing of garbage, so there is no need to worry about fine dust adhering to the inner surface of the main filter or pre-filter falling out, making garbage disposal extremely hygienic. can be done.

In addition, since the bottom of the pre-filter is not open like in conventional filters, dust adhering to the main filter is not visible and does not cause discomfort, making it possible to provide a practical dust collector. It is something.
