FIELD OF THE INVENTION
The present invention relates to an ozone water control valve and more particularly to an ozone water control valve available that can switch between ozone water and tap water.
BACKGROUND OF THE INVENTION
Ozone is the allotrope of oxygen. In the process of ozone decomposition into oxygen, oxygen atoms will free out, because the oxidation of oxygen atoms is quite active, strong reactivity, and oxidation power is second only to fluorine, so that ozone can have sterilization, deodorization, purification effect in the reduction process. Thus, some manufacturers launch the products of water device connecting with the ozone generator so that the tap water can be mixed with the ozone to achieve sterilization, deodorization and purification effect.
However, the conventional ozone water device has following disadvantages: (i) when consumers want to use the above-mentioned ozone water equipment, additional water inlet pipe and water outlet devices are required to install, which greatly increases installation costs, space, and labor and material costs; and (ii) the conventional ozone water device can only control on/off water without a switching function, so that the user need to switch back and forth between multiple faucets, which seriously lowers the convenience of use. Therefore, there remains a need for a new and improved design for an ozone water control valve to overcome the problems presented above.

The first water outlet head has a water chamber axially penetrating through the first water outlet head, and a lateral hole is formed at the lateral side of the first water outlet head to communicate with the water chamber. The first connector comprises an annular base, a rotary control section, and a connecting section which are formed integrally with the first connector. A locating protrude protrudes from one end of the annular base toward the rotary control section, and the other end of the annular base has a protruding axle on the center thereof to connect to the lateral hole. A first water channel axially penetrates from the end of the protruding axle toward the interior space of the rotary control section, and a first hole channel and a second hole channel respectively penetrate through two lateral sides of the rotary control section to communicate with the first water channel.

Structurally, referring to FIGS. 1 to 4, the water filter (14) is installed in the water chamber (11) of the first water outlet head (10), and the first water outlet head (10) is adapted to be connected to the water outlet of the faucet having the outer threaded portion through the first inner threaded section (111). Also, the first inner threaded section (111) is configured to connect to the adapter (15) which has one outer threaded large section (151) and one outer threaded small section (152), and the outer threaded small section (152) is engaged with the first inner threaded section (111) while the outer threaded large section (151) is connected to the water outlet of the faucet, so as to connect to different sizes and types of the water outlet. The first connector (20) is connected to the lateral hole (12) of the first water outlet head (10) through the protruding axle (212), and the first O-ring (214) is disposed on the first peripheral groove (213) of the protruding axle (212), and the protruding axle (212) is screw-locked into the lateral hole (12). Furthermore, the annular base (21) is engaged into the engaging groove (121). Each of the two second peripheral grooves (224) on the two ends of the rotary control section (22) of the first connector (20) has one second O-ring (225) disposed thereon, and the rotary knob (30) is rotatably connected on the rotary control section (22) of the first connector (20). The end of the rotary knob (30) is abutted against the annular base (21), and the locating groove (32) of the rotary knob (30) is coupled with the locating protrude (211) so as to limit the rotation range of the rotary knob (30). An indicating sign (36) is formed on the outer surface of the rotary knob (30) to indicate the rotary control mode, and the rotary knob (30) is rotated to selectively communicate the communicating slot (33) with the first hole channel (221) and the third hole channel (223) or communicate the communicating hole (34) with the second hole channel (222). Additionally, the connecting section (23) of the first connector (20) is connected to the ozone device (50). The lower end of the first water outlet head (10) is connected to the second water outlet head (40) through the second connector (13), and the inner base (42). The second connector (13) is inserted into the through hole (411) of the shell (41), and the inner base (42) is screw-locked in the shell (41), and the connecting hole (421) of the inner base (42) is coupled on the lower portion of the second connector (13) so that the connecting hole (421) having a concaved arc inner periphery is adapted to enable the second water outlet head (40) to rotate along the second connector (13) in different angles, so as to achieve the purpose of changing the direction of water flow. In addition, the second water outlet head (40) comprises a fourth O-ring (43) coupled between the shell (41) and the inner base (42), and the inner periphery of the fourth O-ring (43) is abutted against the outer surface of the second connector (13), so as to secure the position of the second water outlet head (40) after rotated, and meanwhile to keep lubricated between the second water outlet head (40) and the second connector (13), thereby improving the smoothness of the rotation of the second water outlet head (40). Moreover, a third O-ring (426) disposed on the inner periphery of the connecting hole (421) of the inner base (42) is abutted against the surface of the second connector (13), thereby achieving the water leakproof effect.
In actual application, referring to FIGS. 4 to 6, when one end of the locating groove (32) of the rotary knob (30) is abutted against the locating protrude (211) to secure the position thereof, the communicating slot (33) is aligned with the first hole channel (221) and the third hole channel (223), and the first water channel (215) and the second water channel (231) are communicated through the communicating slot (33), so as to communicate the first water outlet head (10) with the ozone device (50). When faucet is opened, the water is adapted to flow downwardly through the water chamber (11), and when the water flows through water outlet channel (131), the flow pressure is adapted to generate the negative pressure siphon effect to the lateral hole (12), so as to further activate the ozone device (50) to release ozone, and the ozone is attracted by negative pressure into the water chamber (11). Thus, the ozone is dissolved into water to enable the water control valve to provide the ozone water containing ozone molecules, so as to achieve the effects of sterilization, deodorization and other purification functions. Additionally, the outlet angle and range of the second water outlet head (40) is configured to be rotated and adjusted through the coordination between the second water outlet head (40) and the second connector (13), so as to facilitate the water use (as shown in FIG. 7).
On the other hand, referring to FIGS. 8 and 9, the ozone water outlet can be turned off by rotating the rotary knob (30) to the other direction, and the other end of the locating groove (32) is abutted against the locating protrude (211), and meanwhile the communicating slot (33) is away from the first hole channel (221) and the third hole channel (223), so that the first water channel (215) and the second water channel (231) are not communicated so as to block the ozone into the first water outlet head (10), and the ozone device (50) is at off status when not receiving the negative pressure. Meanwhile, the communicating hole (34) is aligned and communicated with the second hole channel (222). When the faucet is turned on, the flow pressure generates the negative pressure siphon effect to the lateral hole (12), the outer air is configured to be imported from the air inlet channel (35) into the second hole channel (222), so as to turn off the ozone device 50 and switch to the tap water.
Comparing with conventional ozone water control valve, the present invention is advantageous because: (i) the ozone device (50) is connected to the first water outlet head (10) through the first connector (20) and the lateral hole (12), and with the rotary knob (30), the water control valve can be switched between the ozone water and the tap water quickly and accurately, so as to greatly improve the convenience of use; and (ii) the ozone water and the tap water are used through the same first water outlet head (10), so that there is no need to install another ozone faucet, which effectively saves the costs and space.
Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
