Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a vacuum cleaner that is capable of disposing of dust together with a dust collection bag.

[Conventional technology]

Lately, breathable paper bags have been used as dust collection bags.
Some dust collection bags are designed to be replaced with a new one when it becomes full of dust, but in such cases, the ventilation section of the paper bag becomes clogged with fine dust in a relatively short period of time, and a new dust collection bag cannot be replaced. It was uneconomical to have to replace it. For this reason, as shown in Japanese Utility Model Application Publication No. 51-72979, in order to maintain the dust suction power, the surface of the paper bag was deformed by being struck to remove dust adhering to the inner surface of the paper bag.

[The problem that the idea attempts to solve]

For the above items, paper bags are weak,
Not only is it difficult to install, there is a risk of damaging the paper bag because the paper bag is hit locally, and the vibrations are not transmitted to the entire bag, so it is not sufficiently effective.

[Means to solve the problem]

This proposal was devised to eliminate the above-mentioned drawbacks.According to the present proposal, the paper is stretched to cover almost the entire top surface of the dust collection bag, and by hitting this part, vibrations are transmitted to almost the entire surface of the dust collection bag. This was done to increase the dust removal effect.

[Effect]

This proposal is a vacuum cleaner having an electric blower and a dust collection part, in which an opening is provided in the dust collection part, and a lid body that covers this opening and can be opened and closed freely and has a dust removal body is provided, and the inside of the dust collection part is provided with an opening. The device is removably attached to the dust collection bag, folds the beak paper provided on the dust collection bag into an L shape to form a horizontal part, covers substantially the entire top surface of the dust collection bag with this horizontal part, and connects this horizontal part to the lid body. It is placed in opposition to the provided dust removal body, and when dust accumulates in the dust collection bag, the dust removal body is operated to strike the horizontal part of the mouth paper, transmitting the vibration to almost the entire surface of the dust collection bag. This effectively removes the fine dust collected in the ventilation part of the dust collection bag, thereby increasing the dust absorption rate without the need to replace the dust collection bag with a new one.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.
In Fig. 1, there is a main body case 2 with a built-in electric blower 1, and a case 2 that is detachably attached to the case 2.
It has a dust collection bag 3 made of breathable paper and a dust collection part 5 that houses a dust collection filter 4 made of net, urethane, or polyester, although the details are omitted. It is fixed with glue. The opening 7 of this mouthpiece matches the opening 8 of the dust collection bag.
Each of these openings faces the suction port 9 of the dust collecting section 5, and the dust collecting bag is detachably attached to the dust collecting section.

The beading paper 6 is bent into an L-shape at the top of the figure to form a horizontal portion 10. This horizontal portion 10 is designed to cover the entire upper surface of the dust collection bag 3. An upper lid 11 is attached to the dust collecting section 5 so as to be openable and closable about a hinge 12, and normally covers the opening A of the dust collecting section 5. At the time of closing, the engaging element 14 of the clamp part 13 engages with the locking part 15 of the upper lid 11. The clamp part is provided with a spring 16, and the clamp part 1 resists the elasticity of the spring.
By pressing 3, the engaging element 14 and the engaging part 15
It is starting to come off.

A dust removal body 17 is installed on the upper lid 11.
That is, a substantially T-shaped push button 19 is slidably inserted into a recess 18 provided in the upper lid 11, a flange 20 at the lower end thereof is provided outside the recess 18, and the lower surface of the flange 20 is connected to the mouth paper. It is in contact with the horizontal portion 10 of No. 6. push button 19
A spring 21 is inserted between the lower end of the recess 18 and the lower end of the recess 18.

Since the present invention is constructed as described above, most of the dust sucked through the suction port 9 is collected by the dust collection bag 3, and the dust that cannot be collected is collected by the dust collection filter 4.
The dust is collected and discharged from an outlet (not shown).

If dust collection is continued in this manner, dust will gradually accumulate in the dust collection bag 3, and the ventilation portion of the dust collection bag 3 will become clogged with fine dust, reducing the dust collection efficiency.

In such a state, the push button 19 of the dust removal body 17
When hit, the push button 19 hits the horizontal part 10 of the bag paper 6 through the downward collar part 20 against the elasticity of the spring 21.
When this force is released, the push button 19 returns to its old position due to the elasticity of the spring 21. By repeating this action, the collar portion 20 repeatedly strikes the horizontal portion 10. When the horizontal part 10 is hit in this way, the force is applied to the entire upper surface of the dust collection bag 3, and the fine dust collected in the ventilation part of the dust collection bag 3 is dropped, improving the dust collection effect.

However, dust collection bag 3 has accumulated dust and its dust collection efficiency has decreased.
operates the clamp part 13 to remove the engaging element 14 and the engaging part 15, rotates the upper lid 11 clockwise about the hinge 12, opens the dust collecting part 5, and exits from the opening A to the outside. Take it out and replace it with a new one.

Next, another embodiment of the vacuum cleaner of the present invention will be described. Referring to FIG. 2, in which the same parts as in FIG. An opening 32 is provided in the section.

A support plate 33 fixed within the dust collecting section 5 is provided on the lower surface of the support plate 31, and this support plate is also provided with an opening 34 that matches the opening 32 of the support plate 31.

Therefore, when the dust remover 17 is operated as described above, the dust in the dust collection bag 3 will protrude downward through the openings 32 and 34 of the support plate 31 and the support plate 33 together with the dust collection bag. It is convenient because it accumulates dust so that it can continue to collect dust.

Furthermore, as shown in FIG.
If a handle hole 35 is provided near the tip of the dust collection bag 3, when the dust collection bag 3 is removed from the dust collection case 5, the fourth
As shown in the figure, by standing the horizontal portion 10 upright, it is convenient to easily reach into the handle hole 35 and take it out.

In addition, as shown in FIG. 5, by providing a fold line 37 on the upright part of the bag 6 that is folded in the opposite direction to the fold line 36 with the horizontal part 10, when the dust collection bag 3 is taken out as described above, this fold line 37 is provided. When the horizontal part 10 is bent along the fold line 37, the horizontal part 10 covers the opening 7 of the bag 6 as shown in FIG. 6, so that the dust in the dust collection bag 3 does not spill out from the opening 7, which is convenient.

[Effect of idea]

As described above, according to the present invention, the dust collection bag is easy to attach, has a simple structure, and can easily transmit vibration to the entire dust collection bag without damaging the dust collection bag. Since it is possible to collect fine dust that has accumulated in the bag, it is possible to obtain the sustainability of the dust collection bag.
