Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a vacuum cleaner, and particularly to a paper filter thereof.

[Prior art]

One of the drawbacks of vacuum cleaners is that the dust remaining in the dust collection case may emit an unpleasant odor indoors due to the exhaust flow from the vacuum cleaner, or when disposing of the dust, etc. It happened that there was an unpleasant odor.

Further, in the past, it has been necessary to use a component called a dust indicator to indicate when to discard the garbage when the amount of garbage, etc. exceeds a predetermined amount in the dust collection case.

Furthermore, in order to improve the dust collection efficiency of paper bag filters, there are some paper bag filters that have a double filter section, but the dust collection efficiency of these filters is still insufficient.

[Summary of the idea]

This idea was made to improve the shortcomings of these conventional filters, and the paper bag filter used in vacuum cleaners has a double filter section, an inner filter and an outer filter, and an oil-based fragrance is added to the outer filter. By impregnating it with the agent, the unpleasant odor emitted from the vacuum cleaner disappears, and at the same time,
Displays when to replace the paper bag filter, and also
The purpose is to improve the dust collection efficiency of paper bag filters.

[Example of the invention]

Hereinafter, embodiments of this invention will be described with reference to the accompanying drawings.

1 to 4 show an embodiment of this invention.

In the figure, 1 is a main body case with a built-in electric blower 2, 3 is a dust collection case detachably attached to the front part of the main case 1 with a locking member 4, and the front opening of this dust collection case 3 is has a front lid 5 that can be opened and closed freely, and an inlet 6 is formed in the center. Reference numeral 7 denotes an inner lid fixed to the inside of the front lid 5, which has an opening 8 in the center that matches the intake port 6, and a packing 9 is attached to the outer periphery, and this packing 9 is used to collect the dust. Case 3
and seals the inner lid 7. 10 is a prefilter container having an opening 11 at one end and a closed surface 12 at the other end, a net 13 is fixed to the side wall of the prefilter container, and the container is housed inside the dust collecting case 3. Reference numeral 14 denotes a disposable paper bag filter formed by a cap 15 and a filter section 16. The cap 15 has a dust suction port 17 and an eyelet 18 rotatably attached to the center of the cap 15. It has a lid part 19 that opens and closes the mouth 17. Further, the cover sheet 15 is made of cardboard.

The filter section 16 is formed of double layered paper, an inner filter 20 and an outer filter 21, and the outer filter 21 is impregnated with an oily fragrance. A main filter 22 is detachably attached to the rear opening of the dust collecting case 3, and its periphery is sealed with a rubber packing 23. Reference numeral 24 denotes a check valve made of rubber or the like, which is held between the front lid 5 and the inner lid 7, and is opened when a hose is inserted, but is opened when a hose is not inserted. The structure is such that the inside is almost sealed.

Next, the operation of the device configured as described above will be explained.

When air mixed with dust and the like is sucked into the dust collection case 3, the dust and the like are first passed through the filter section 16 of the paper bag filter 14, and then passed through the net of the pre-filter container 10 to the main filter 22.
In addition, the paper bag filter 14 filters out fine dust, passes through the electric blower 2, and clean air is discharged to the outside of the main body case 1.

In the above case, the oil-based aromatic agent impregnated into the outer filter 21 is dispersed to the outside of the main body case 1 by the flow of air, so that unpleasant odors such as dirt can be eliminated. In addition, since it is oil-based, the time that the scent from the aromatic agent is released can be extended.

Next, when dust etc. accumulate in the paper bag filter 14, the amount of air passing through the paper bag filter 14 decreases, and the scent of the aromatic agent emitted to the outside of the main body case 1 due to the air flow also decreases. , it is possible to determine whether the device is clogged with garbage or the like.

When the vacuum cleaner is not in operation, the inside of the dust collection case 3 is sealed by the packing 9 formed on the outer periphery of the inner lid 7, the rubber packing 23 of the main filter 22, and the check valve 24, so that no fragrance is emitted from the air freshener. However, when disposing of garbage or the like, the front lid 5 is opened, exposing the outer filter 21 of the paper bag filter 14, allowing the fragrance to be emitted and eliminating the unpleasant odor of the garbage, etc.

[Effect of idea]

According to this invention, as explained above, the outer filter of the paper bag filter is impregnated with an aromatic agent, so that when the vacuum cleaner is in operation, the airflow disperses it outside the main body of the vacuum cleaner, so that dust and dirt can be removed. can eliminate unpleasant odors. Also,
When the vacuum cleaner stops running, the airflow disappears, and so does the scent from the air freshener.

Furthermore, when the paper bag filter becomes clogged with dust, etc., the amount of air flowing through it decreases, so the fragrance emitted by the aromatic agent also decreases, making it possible to determine that the paper bag filter is clogged with dust, etc. Moreover, since the paper bag filter is discarded along with garbage, etc., a new paper bag filter is always installed, the fragrance does not deteriorate, and there is no need for troublesome work such as replenishing the fragrance. Furthermore, since a new paper bag filter is always installed, the amount of scent emitted is also approximately constant, so the amount of stored garbage and the amount of scent emitted changes in a reliable manner, so it can be used as a dust indicator. .

In addition, when the vacuum cleaner is not operating, it is almost sealed by the packing, rubber packing, and check valve, and no fragrance is emitted by the air freshener, but when disposing of garbage, etc., open the front cover. By doing so, the outer filter is exposed, and by emitting the scent of the aromatic agent, it is possible to eliminate the unpleasant smell of garbage when disposing of garbage.

Furthermore, since the outer filter of the filter section is impregnated with an oil-based aromatic agent, a kind of cleaning dust collection can be performed, which improves the dust collection effect of the paper bag filter.

At this time, if the inner filter is impregnated with an oil-based fragrance, the filter portion will become clogged more quickly, but since the outer filter is impregnated with an oil-based fragrance, the clogging time can be lengthened.
