Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention (a) Field of Industrial Application This invention relates to a shower device for mixing liquid perfume or the like into the shower.

(B) Conventional technology Conventionally, shower devices that allow fragrances, medicines, detergents, etc. to be mixed into the shower have been developed, for example, in Japanese Patent Laid-Open No. 60
There are those described in Japanese Patent Publication No.-852, Japanese Patent Publication No. 46-26548, and Japanese Utility Model Application Publication No. 144834-1983.

These devices have a cake-like fragrance body interposed in the flow path of the shower head so that the fragrance can be melted during shower use, and the chemicals are placed in a flow path separate from the shower flow path. The detergent chamber attached to the shower head is connected to the shower spout by making a hole in the partition wall between the shower head and the shower head. By operating a push button, the detergent is artificially sprayed from the detergent to the shower spouting part.

(c) Problems to be Solved by the Invention However, these prior art techniques have various drawbacks. For example, in the case where a cake-like fragrance is interposed in the flow path of a shower head, the fragrance is Because it is exposed in the flow path in solid form, melts, and enters the shower flow path, the molten charcoal becomes sparse, and there is a risk that the dissolved concentration of the fragrance may change, especially depending on water pressure and shower temperature. It is troublesome to refill the fragrance, and the structure of the shower head becomes complicated. In addition, if a drug storage chamber is attached to the flow path and many holes are punched in the partition wall between the chamber and the flow path, the fragrance will be mixed into the flow path, and the difference between when the fragrance is used and when it is not used. There are drawbacks such as difficulty in switching. Furthermore, if a shower head is equipped with a detergent chamber or the like and the detergent etc. is ejected along with the shower by manual operation such as a push button, the weight of the head increases due to the structure of the shower head. Moreover, detergent etc. are ejected instantaneously, and in order to continuously eject detergent, it is necessary to push a difficult-to-understand push button.
