Description

A vacuum cleaner with an aromatic micro-capsule

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scented vacuum cleaner, and more particularly, to a vacuum cleaner in which a microcapsule odor is embedded in a cleaner for a long time.

As shown in FIG. 1, a general vacuum cleaner includes a suction unit 15 which sucks dust or foreign matter (hereinafter referred to simply as 'dust') according to the suction of air, which is sucked through the suction unit 15. It comprises a connecting pipe 13 for transporting dust and the like, and a main body 11 for collecting dust and the like sucked from the connecting pipe (13). Usually, the main body 11 is equipped with a motor (not shown) to generate a strong suction force, dust or the like sucked through the connecting pipe 13 according to the suction power of the motor is collected in the collection chamber of the main body, air Is discharged through the outlet. However, as the conventional vacuum cleaner 10 is used, the odor of carbon powder generated from the motor or the odor coming from the exhaust air tends to be severely generated.

In order to solve this problem, many vacuum cleaners incorporating fragrance in a cleaner have been recently disclosed. Among them, as shown in Fig. 2, in the Utility Model Utility Model No. 99-28949, a perfume 24 is built in the rear of the motor 22 of the main body 21, and is heated by the exhaust heat of the motor 22. A vacuum cleaner 20 is disclosed in which a fragrance is generated. Reference numeral 26 in FIG. 2 denotes a dust collecting filter. The vacuum cleaner extends the service life of the air freshener to some extent by preventing the air freshener from being consumed when the vacuum cleaner is not used. However, since these types of vacuum cleaners all use a common fragrance, the life of the fragrance is very limited compared to the service life of the vacuum cleaner.

The object of the present invention is to provide a new vacuum cleaner which can last a long period of time unlike the existing directional vacuum cleaners.

The microcapsule flavor vacuum cleaner of the present invention for achieving the above object is characterized in that, in a conventional vacuum cleaner, a filter containing a microcapsule flavor is embedded in the main body of the cleaner.

That is, the vacuum cleaner according to the present invention belongs to the present invention as long as the vacuum cleaner includes a filter containing a microcapsule in the body of the cleaner, regardless of the vacuum cleaner or the wired vacuum cleaner.

Hereinafter, the vacuum cleaner of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is an example of a wireless vacuum cleaner to which the present invention is applied, which is a "handheld vacuum cleaner" filed by the present applicant and registered as a registered utility model No. 178902. As can be seen in the internal structure shown in FIG. 4, the vacuum cleaner 30 is driven by the power generated from the charging battery 33 mounted inside the main body 31, the motor 32 is driven, The dust 32 is sucked in through the suction port 35a of the dust collecting chamber 35 as the 32 is driven, and the sucked dust has a structure in which the dust collecting filter 36 is collected.

As shown in FIG. 5, the dust collecting filter 36 is surrounded by the filter paper 34 in the frame 36a, and dust, which is sucked with the intake of air, on the outer surface of the filter paper 34. As shown in FIG. It has a structure that is collected. In Fig. 4, reference numerals 37, 38, 39 denote "fan", "lamp", and "switch part", respectively.

The vacuum cleaner 30 of the present invention is characterized in that the microcapsule flavor is contained in the filter 36.

The microcapsule flavor refers to a capsule having a size of about 10 μm or less in which an oil flavor is internally enclosed and surrounded by a double coating. The general oil fragrance is over 60 ° C. is scented and disappears, even if coated on the fabric can not maintain the fragrance long, while the microcapsule fragrance can maintain the fragrance for a long time while having heat resistance to about 280 ℃. Such microcapsule fragrances are already known in various documents (Publication Publication No. 99-53572, etc.) and are widely used in various fields, such as flooring materials (registered utility model 163147), gum wrappers (utility model publication 96-27094), scented lotteries (practical). It is used for the release of the new model 95-32550), the directional deposit account book (the utility model publication 95-27032), and the direction card (the utility model publication 95-5965). Microcapsule flavors vary depending on the type of oil flavor, such as peppermint, lavender, sol, rose, jasmine, freesia, acacia, violet, lilac, flavono, rosemary, apple, grape, banana, orange and mango. Any one from the group consisting of natural and artificial flavors such as strawberry, cherry, lemon, phytoncide, plum, quince, mugwort, pheromone, chocolate, coffee, vanilla, cola, olive, grazilia, hazelt, ginseng and lime You can choose.

The present invention applies such a microcapsule to the filter of the vacuum cleaner so that the fragrance is possible for a long time in the vacuum cleaner. Specifically, in the present invention, the microcapsule flavor is coated on the filter paper 34 of the filter by applying the microcapsule flavor to the filter paper or dipping the filter paper onto the microcapsule flavor. The filter paper may use an aluminum material or an emulsified product as well as a nonwoven fabric, a fabric such as a fabric, and generally has a network structure.

However, coating the microcapsule fragrance so as to be contained in the filter paper is one of the very difficult tasks due to the characteristics of the vacuum cleaner which must consider air permeation. In the present invention, after measuring the weight of the filter paper in consideration of the filter function of the vacuum cleaner, it is preferable to contain a microcapsule flavor of 10% by weight or less based on the weight of the filter paper. If the microcapsule flavor exceeds 10% by weight based on the weight of the filter paper, the suction power of the cleaner is greatly reduced. More preferably it is to contain 4 to 8% by weight of the microcapsules with respect to the weight of the filter paper.

The binder used for coating the microcapsule flavor on the filter paper is preferably a silicone or urethane binder. In addition, the amount of the binder added is preferably about 50% of the amount of the microcapsule flavor.

After the filter paper is coated, it is dried. It is good to perform drying at the temperature of 100-180 degreeC. The coated filter paper thus dried does not dissipate the fragrance of the microcapsules coated on the filter paper even after washing, and furthermore, even if the filter paper is broken or worn out, the fragrance may last for a long time. In addition, the directional vacuum cleaner according to the present invention, by the microcapsule is attached to the filter, the odor is achieved 20 to 30% in the non-operation state, 70 to 80% during operation. To this end, in the case of the present invention, the microcapsule-containing filter is preferably mounted between the suction port of the main body of the cleaner and the motor.

Hereinafter, embodiments according to the present invention will be described in detail.

EXAMPLE

In order to compare with a conventional vacuum cleaner, first, a microcapsule-coated filter was manufactured. The microcapsule flavor was mixed by stirring an aqueous solution containing 25% by weight of oil flavor at a speed of 8000 to 10000rpm, and then adding about 2% by weight of polyvinyl alcohol (mug gum) to the range of 60 ° C. It stirred with the temperature heated and obtained the capsule in which the film (volume film) was formed. Then, melamine resin (resin such as polyurethane or gelatin) is added thereto and stirred at 60 ° C. to 70 ° C. at 3000 ° C. to 4000 rpm, and when the temperature is gradually lowered, the resin hardens to form a hard main film. A microcapsule flavor of about 5 μm in size and consisting of 83% by weight of oil, 6.8% by volume, and 10.2% by weight of main film was prepared.

Thus prepared microcapsule flavor about 10% by weight based on the weight of the nonwoven fabric, and diluted well with water, it was prepared in a coating solution to which 5% by weight of a silicone binder was added.

Thereafter, the coating solution was coated on a nonwoven fabric which is commonly used as a purifier and coated, and dried at about 150 ° C. to produce a filter paper of the present invention. As a result of using the filter paper prepared in the vacuum cleaner, the smell lasted for about 6 months.

As described above, the vacuum cleaner according to the present invention is a new vacuum cleaner which can be used for various types of fragrances, with long-lasting odor and almost no consumption of fragrance, having a long service life equal to or longer than the life of the filter. It is effective to provide.
