Problems solved by technology

However, if the amount of air bubbles added is too small, the water-saving effect will not be obvious, and if the amount of air bubbles added is too large, the feeling of use when the water flow touches the skin will deteriorate

Embodiment 1

[0106] figure 1 Shown is a longitudinal sectional view of the water-saving hydrant of Example 1.

[0107] When installing this water-saving cock 10, it is inserted into the middle of flexible pipe or running water pipe. Shown in the figure is a water saving plug 10 , a tap water pipe 12 is connected to its upstream end 11 , and a pipe 15 is connected to its downstream end 13 . The water pipe 15 is a hose of a shower or a pipe of a water tap. For example, a shower head 16 is connected to the downstream side of the pipe 15 . In addition, it may also be connected to the kitchen tap 17 . The water-saving hydrant 10 utilizes figure 1 For the cross-sectional structure shown, air bubbles were added to tap water. At the same time, the flow rate of the water is increased, thereby increasing the impact force when the water touches the user's hand or skin. Therefore, even if the amount of water is reduced, the feeling of use will not be changed. Therefore, water bills can be sav...

Embodiment 2

[0128] Figure 10 Shown is the water-saving hydrant of Example 2, (a) is a perspective view of the orifice unit 86, and (b) to (d) are longitudinal sectional views of various modifications of the orifice unit 86 , (e) shows a longitudinal sectional view of the state where the orifice unit 86 is installed in the water-saving cock of Embodiment 1, and (f) shows that the water-saving cock of Embodiment 1 is partially deformed and the section is installed. A longitudinal sectional view of the state of the orifice unit 86 . In addition, only one air suction port 30 is provided in this example. The air suction ports 30 only need to be provided with the necessary number.

[0129] In this embodiment, the orifice portion 20 ( figure 1 ), instead adopting a unit structure that is separated from other parts. The orifice unit 86 is detachably fitted into the water receiving cylinder portion 18 of the faucet. Such as Figure 10 As shown in (a) and (b), the orifice unit 86 is formed ...

Embodiment 3

[0135] Figure 11 Shown is the one-way valve installed in the water-saving hydrant of Example 3, (a) shows a longitudinal sectional view of the one-way valve, and (b) shows an exploded oblique view thereof.

[0136] The one-way valve 64 is inserted into the water-saving plug ( figure 1 ) inside of the air intake port 30. It is a cylindrical body with a tapered hole 68 at one end and accommodates a ball 66 and a stopper 70 embedded therein. One end of the tapered hole 68 has an inner diameter larger in diameter than the ball 66 , and the other end has an inner diameter smaller in diameter than the tapered hole 68 . Thus, when the ball 66 is pushed against the inner surface of the tapered hole 68, it will block the side of the tapered hole 68 of the one-way valve 64. The stopper 70 is a plate for preventing the ball 66 from falling out, and has a plurality of through holes through which air or water can pass.

[0137] Adopt the one-way valve 64 of this structure, allow air ...

Abstract

A water saving valve is fitted to a hose or a water pipe and mixes air bubbles with water. Water receiving flask part 18 receives tap water from a water pipe 12. Tapered hole part 20 has a flow path whose cross-sectional area is gradually reduced from the upstream side toward the downstream side. Conduit part 32 has a large diameter section 56 and a small diameter section 57. The large diameter section 56 is linked to the tapered hole part 20. The conduit part 32 has a flow path 38 at an axial part thereof whose cross-sectional area is substantially uniform. The large diameter section 56 has an air suction port 30 running through from the flow path 38 of the axial section to the outer peripheral surface. A check valve 64 is inserted into the air suction port 30. Sleeve 50 is rigidly secured to the conduit part 32 by a support body 44 arranged at part of axial hole 90. The sleeve 50 has an eaves-like section 46. The eaves-like section 46 surrounds the outer peripheral surface of the large diameter section 56 with a gap 48 interposed between them. The sleeve 50 surrounds the periphery of the other end of the conduit part 32 with a space interposed between them. Air is sucked in from the gap 48 through the air suction port 30 so that water does not leak if hydraulic pressure is applied in the opposite direction.

Description

technical field [0001] The present invention relates to a water saving cock having the function of adding air bubbles to the water supplied through a hose or water pipe. Background technique [0002] The prior art discloses a device that is installed on a kitchen utensil or a shower head and adds a large amount of air bubbles to supplied tap water (please refer to Patent Document 1) (please refer to Patent Document 2). The device is used to prevent water splashing during washing and improve the use feeling when the water flow of the shower touches the skin. [0003] Prior technical literature: [0004] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2005-205326 [0005] Patent Document 2: (Japanese) Unexamined Patent Publication No. 2008-237601 [0006] The known prior art has the following problems to be solved. [0007] If a large amount of air bubbles are added to the water when the water is supplied to the shower head, not only can the use feeling be ...
