Abstract

An ozone faucet contains a body and a mixer. The body includes an outlet end and an ozone tube, and the outlet end has inner threads for screwing with a casing, between the casing and the outlet end is defined an accommodating space. The mixer includes a water guiding member, a resilient element, and a check tube. The water guiding member has a groove and a plurality of increasingly conical orifices, the resilient element is accommodated in the groove and has a stopping plug pushed by the resilient element. The check tube has a disc covering the water guiding member, the disc has a plurality of decreasingly conical apertures matching with the plurality of increasingly conical orifices The check tube also has a channel passing therethrough and contacting with the stopping plug, the mixer is secured in the accommodating space, and the check tube connects with the ozone tube.

Claims

1. An ozone faucet comprising:

a body including an outlet end and an ozone tube disposed on the outlet end, and the outlet end having inner threads defined around an inner wall thereof and screwing with a casing, between the casing and the outlet end being defined an accommodating space;

a mixer including a water guiding member, a resilient element, and a check tube, the water guiding member having a recess defined on a central portion thereof and a plurality of increasingly conical orifices surrounding around the recess, and a wide end of each increasingly conical orifice facing to a lower end of the casing, the resilient element being accommodated in the recess and having a stopping plug pushed by the resilient element, the check tube having a disc covering the water guiding member, the disc having a plurality of decreasingly conical apertures matching with the plurality of increasingly conical orifices, and a narrow end of each decreasing conical aperture facing to the water guiding member, and the check tube also having a channel passing therethrough and contacting with the stopping plug, the mixer being secured in the accommodating space, and the check tube connecting with the ozone tube.

2. The ozone faucet as claimed in claim 1, wherein the water guiding member also has a plurality of holes adjacent to the plurality of increasingly conical orifices and opposite to a plurality of bosses on the disc of the check tube.

3. The ozone faucet as claimed in claim 2, wherein each boss has a spacing portion formed on a bottom end thereof so as to contact with each hole such that a clearance is defined between the water guiding member and the check tube.

4. The ozone faucet as claimed in claim 1 further comprising a fixing member, and the fixing member having a housing and a screw loop for screwing with the housing, such that the housing and the screw loop screw together to cover the mixer, wherein the housing has a first opening for corresponding to a second opening of the screw loop, and the plurality of decreasingly conical apertures communicate with the plurality of increasingly conical orifices.

5. The ozone faucet as claimed in claim 4, wherein the housing also has a first washer mounted in the first opening, and the screw loop has a second washer secured in the second opening.

6. The ozone faucet as claimed in claim 4, wherein the housing further has a peripheral rib arranged around an outer rim thereof, and the peripheral rib has a sealing ring fitted thereon and abutting against the inner wall of the outlet end.

7. The ozone faucet as claimed in claim 1, wherein the casing has a screwing section formed around the lower end thereof so as to screw with a spray component.

8. The ozone faucet as claimed in claim 7, wherein the spray component is a shower head.
