Ozone-based disinfecting device comprising a flow sensor
First Claim
1. An ozone-based disinfecting device comprising a mixer having a generally hollow body with a water inlet for water under pressure;
- a spray nozzle for generating a generally conical spray of water introduced by way of the water inlet;
a contact chamber communicating with a gas inlet for ozone rich gases;
an outlet aperture from the contact chamber with the outlet aperture being coaxial with the spray nozzle and spaced apart therefrom, and a flow sensing device positioned within a pocket in the mixer, wherein the pocket is comprised of a closed first end, surrounding walls, and an opening communicating with an exterior of the hollow body opposite the first end, between the water inlet and the outlet aperture, wherein the flow sensing device is for sensing the extent of flow of water through the spray nozzle, wherein the flow sensing device is an electronic flow sensing device for sensing vibration caused by a flow of water through the mixer, and includes a piezoelectric sensor and an associated circuit for generating a signal indicative of the rate of flow of water through the mixer, and wherein a periphery of the piezoelectric sensor is embedded in a settable material.

Abstract
An ozone-based disinfecting device is provided comprising a mixer having a generally hollow body with a water inlet for water under pressure, a spray nozzle for generating a generally conical spray of water introduced by way of the water inlet, a contact chamber communicating with a gas inlet for ozone rich gases, and an outlet aperture from the contact chamber that is coaxial with the spray nozzle and spaced apart therefrom. An electronic flow sensing device senses the extent of the flow of water through the spray nozzle according to vibration caused by water flowing through the mixer. The electronic flow sensing device is preferably located in a pocket formed in the mixer and preferably comprises a piezoelectric sensor embedded at least around its periphery in a settable material. A preferred construction of the mixer is also described.
