Abstract

PROBLEM TO BE SOLVED: To forcibly jet water by a mixture of water and sucked air by allowing air to be automatically sucked in a shower casing without altering the use amt. of water. SOLUTION: A conical member 3 is provided in the passage 6 of a shower casing 1 to increase flow rate to form a negative pressure region, an air suction hole (pipe) 4 communicating with the outside is provided to the center of the upper part of the conical member 3 to automatically suck air, and an air suction selecting opening and closing valve 5 is attached to the inlet of the air suction hole 4 outside the casing 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims to increase the jetting force of a shower without changing the amount of water used.
That is, according to the amount of water used, air is sucked into the casing 1, and the total volume is increased by the amount of water used + the amount of intake air.
At the same time, by utilizing the expansion force of air, shower injection is performed from the injection port 2 with good water force.

[0002]

2. Description of the Related Art Conventionally, increasing the amount of water used or increasing the water pressure used to increase the shower jetting is not a one-touch operation because the operation is troublesome. However, the amount of water used increases and it becomes an economical burden.
In addition, the injection up device which is commercially available at present simply strengthens the injection force by narrowing the outlet of the casing 1. Therefore,
Needless to say, the spray width has become narrower, halving the original value of the shower.

[0003]

Therefore, at present, in order to intensify the injection, the amount of water used is increased or the water pressure used is increased, but it does not mean that the valve is simply opened. Absent. When hot water or the like is used, it is necessary to adjust the temperature, and when raising the water pressure, it is necessary to pump up or the like. There is also such an annoyance, and in this case, the amount of water used increases and it becomes an economical burden,
It is also a resource loss. For current commercial products,
As mentioned above, the spray width has become thinner and the original freshness of the shower has been lost.

[0004]

[Means for Solving the Problems]

(A) The conical body 3 is provided in the shower casing 1 to increase the flow velocity and generate negative pressure. (B) An air suction hole 4 is provided in the upper part of the cone 3 to suck air from the outside. (C) An opening / closing cock 5 for air intake is provided outside, and air intake is selected by one-handed operation.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Since the water flow inside the casing 1 passes around the conical body 3, the flow path gradually narrows, and accordingly the flow velocity becomes high. Then, it reaches the upper part of the conical body 3, reaches the maximum flow velocity, and is jetted up in a columnar shape. Therefore,
Negative pressure is generated inside this, and if the opening / closing cock 5 is opened through the air suction hole 4 at the center, air is sucked from the outside. In this case, the intake air is on the inner side and the water sprayed in a columnar shape is on the outer side, so that the mixing is fast and can be completely mixed in the casing 1 for a short time. Therefore,
It has a strong jetting force and is jetted without spots. In this case, the amount of water used does not change, and depending on the amount of intake air,
Injection force of more than% increase is obtained.

[0006]

【Example】

(A) When the inner diameter of the casing 1 is 15 mmφ, the gap between the casing 1 and the conical body 3 is appropriately about 1 mm. The flow velocity is fast,
The amount of water also flows sufficiently. (B) Since the intake air is on the inside and the water is on the outside, the mixing speed is fast and can be completely mixed in the short casing 1. On the contrary, if the water is on the inside and the intake air is on the outside, it will be mixed. The rate is also poor, and therefore the jetting becomes uneven and the water force becomes weak. (C) It was confirmed that good and bad mixing of water and air is greatly related to the injection force.

[0007]

【The invention's effect】

(B) The amount of water used is not changed, the shower power can be easily increased with one hand, and since it is performed with air, it saves water and is economical. (B) In addition to improving the jetting power, it is a mixture of air and water, so it is ideal for washing hair and washing off soap, and has a great effect.
