Description

Detailed Description of the Invention (a) Field of Industrial Application The present invention relates to mixing of a perfume and the like so that a mixed liquid such as a liquid perfume can be mixed into a shower by utilizing a flow pressure difference in the middle part of a shower channel. Regarding the shower device.

(B) Conventional Technology Conventionally, as a shower device in which a fragrance, a medicine, a detergent or the like can be mixed in a shower, for example, JP-A-60-
852, Japanese Patent Publication No. 46-26548, and Actual Development No. 50-144834.

These are those in which a cake-shaped fragrance material is interposed in the flow path of the shower head so that the fragrance can be used while being dissolved in the shower. A chamber is attached, and the drug is mixed into the channel through the pores formed in the partition wall with the channel, and the detergent chamber attached to the shower head is connected to the shower and the ejection part. By pushing the button, the detergent is artificially spouted from the detergent chamber to the shower spout.

(C) Problems to be Solved by the Invention However, these prior arts have various drawbacks. For example, the one in which a cake-like fragrance is interposed in the flow path of the shower head is Since it is a solid that is exposed to the channel and melted and mixed into the shower channel, the solubility becomes sparse, and there is a possibility that the dissolved concentration of the fragrance may change due to water pressure or shower temperature. It has drawbacks such as complicated refilling of fragrance and complicated shower head structure, and a drug storage chamber is attached to the flow channel, and a large number of holes are formed in the partition wall between the chamber and the flow channel. However, there is a drawback that it is difficult to mix the fragrance into the flow path, and it is difficult to switch between when the fragrance is used and when the fragrance is not used. To spray detergent etc. with the shower Ones, there is complication to the manual operation during showering, structural head weight of the shower head is increased, the showerhead Handei method, the gripping operation has the disadvantages of such hard performed.

(D) Means for Solving the Problems In the present invention, a flow pressure difference generator is provided in the middle of the shower channel, and a separately provided liquid mixture such as a liquid fragrance is stored in the shower channel on the high flow pressure side. The liquid extrusion side of the tank is connected,
By providing a shower device for mixing perfume and the like, in which the liquid discharge operation side of the mixed liquid storage tank is connected to the shower flow path on the low flow pressure side, all of the above drawbacks can be eliminated. .

(E) Operation In the present invention, when the shower water is circulated in the flow path to use the shower, the flow pressure difference generator is disposed in the middle part of the flow path. The side where the flow pressure difference occurs and the flow pressure is high communicates with the liquid extruding side of the separately provided mixed liquid storage tank, so that the mixed liquid is pushed out of the tank by the shower water flow pressure. On the other hand, the side with a low flow pressure communicates with the liquid discharge action side of the mixed liquid storage tank, and the extrusion action from the side with a high flow pressure is better than the side with a low fluid pressure from the liquid discharge action side. It is discharged to the flow path of No. 1 and mixed with a mixed liquid such as a fragrance into the shower water.

(F) Effect According to the present invention, since the flow pressure difference generator is provided in the middle of the shower channel, the flow pressure difference can be generated, and the mixed fluid storage tank can be generated by the high flow pressure in the shower channel. Liquid perfume inside can be pushed out from the same tank at the same time,
The liquid perfume or the like can be sucked into the shower channel from the mixed liquid storage tank due to the low flow pressure in the shower channel. Therefore, it is possible to automatically and smoothly mix the liquid perfume or the like in the mixed liquid storage tank into the shower water flowing through the shower channel without any manual operation.

(G) Example To explain the example of the present invention in detail with reference to the drawings, FIG. 1 is an overall explanatory view showing a usage state of the device of the present invention,
