The ozone concentration sensing module 170 is disposed in the outer casing 114 and located in the outer duct Do. The ozone concentration sensing module 170 includes a sensing chamber 172, an ozone concentration sensing circuit module 174, a three-way switching valve 176, and an air extracting device 178.

The sensing chamber 172 provides a space for the ozone concentration sensing circuit module 174 to be placed, and serves as a gas collecting space at the time of detection, and its appearance is not limited. The sensing chamber 172 has an air inlet 172a and an air outlet 172b. The ozone concentration sensing circuit module 174 is fixed in the sensing chamber 172. The ozone concentration sensing circuit module 174 may include, for example, a circuit board and an ozone concentration sensing chip mounted on the circuit board (eg, a small circuit board) and then via an external signal line. Connected to the treatment host; or it can be a circuit board with a display interface and a gas sensing function interface, and the display concentration can be displayed through the display panel mounted on the handheld device.

The three-way switching valve 176 can be a conventional general switching valve that is fixed to the sensing chamber 172 and has a valve member 176v, a first passage 176a, a second passage 176b, and a third passage 176c, and is formed by a valve member 176v, The opening and closing between the first passage 176a and the second passage 176b and the third passage 176c are switched. The first passage 176a is in communication with the intake port 172a, the second passage 176b is for passing the gas to be tested, and the third passage 176c is for introducing the flushing gas. The first passage 176a may be in direct communication with the intake port 172a or may be connected via a suitable conduit. The second passage 176b communicates to a first position of the outer side of the outer casing 114, such as a location near the treatment end connector 120, i.e., near a location where ozone may leak, to detect possible leaks as early as possible. The third passage 176c is communicated to a second position of the outer side of the outer casing 114, such as a position away from the treatment end connector 120, ie, a location away from possible leakage of ozone, for pumping in A near zero ozone gas (such as outside air) is used as the flushing gas described above. Valve member 176v can be coupled to controller 156.

The air extracting device 178 may be fixed to the sensing chamber 172 and communicated with the air outlet 172b and located on the downstream side of the air outlet 172b; or may be further connected to the vacuuming device 154 of the treatment host 150 through a pipeline. In addition, since the ozone concentration sensing module 170 is located in the external pipe Do, when the external pipe Do has been connected to the vacuuming device 154 of the treatment host 150, the air extracting device 178 may be omitted, leaving the air outlet 172b and the outside. The conduits Do are in communication and provide a pumping function via the treatment host 150. The air extraction device 178 includes a fan, a blower, and the like. The air outlet 172b can be configured to match the air extracting device 178, whereby the air extracting device 178 can be directly fixed in the air outlet 172b of the sensing chamber 172, or can be formed by a suitably shaped pipeline. The air outlet 172b is connected to the air extracting device 178.

[Ozone concentration sensing method]

Please refer to FIG. 15, which illustrates an ozone concentration sensing method in accordance with an embodiment of the present invention.

The ozone concentration sensing method comprises the following steps: in step S500, a sensing chamber (such as the sensing chambers 172, 272) is provided, and an ozone concentration sensing circuit module is fixed in the sensing chamber.

The gas sampling step (step S600), the gas to be tested is sent to the ozone concentration sensing circuit module to detect the ozone concentration. Specifically, the ozone concentration sensing circuit module reacts to output a voltage, for example, several tens of millivolts (mV), or hundreds of millivolts, depending on the ozone concentration of the input gas to be tested. The detection capability of the module is different from the gas to be tested.

The gas flushing step (step S700) delivers the flushing gas to the ozone concentration sensing circuit module. Specifically, this step is to perform a flushing of the sensing chamber originally filled with the gas to be tested, and the flushing gas is a zero-oxygen gas, such as external air.

In step S800, the gas sampling step (S500) and the gas flushing step (S600) are alternately repeated at a predetermined time interval. The predetermined time interval is, for example, 10 seconds, or any other length of time, depending on the condition of the gas to be tested, for example, the sampling step is 1 second, the gas flushing step is 3 seconds, the rest is 10 seconds, and then the sampling step is repeated, and the gas is flushed. Steps, etc. For example, if the ozone concentration sensing method is applied to a human body such as the ozone disinfecting hand-held device of the present invention for a long time, the predetermined time interval can be shortened, and the long time interval can be appropriately pulled.

In order to further extend the life of the ozone concentration sensing circuit module, The dilution step is added to dilute the gas to be tested, so that the gas to be tested has been diluted before reaching the ozone concentration sensing circuit module.

In addition, the inventors of the present invention have found that there is a good linear relationship between the sensed data for correcting the ozone concentration by means of a proportional value. This is a method created by the inventors of the present invention, as explained below.

The rinsing gas is supplied to the ozone concentration sensing circuit module, and the ozone concentration sensing circuit module reflects a background voltage (step S420), and the background voltage is a rough value of the peak voltage decreasing degree, such as the background voltage of FIG. 1~5, which shows the background voltage after time 1~5.

In step S430, the steps of providing a known concentration of ozone and the step of providing a flushing gas are alternately repeated, for example, providing a known concentration of ozone from time 1 to time 5, respectively (for example, providing two known concentrations of ozone, or more Knowing the concentration of ozone), during which the flushing step is alternated, and the relationship between the peak voltage and the background voltage (ie, the peak voltage/background voltage) and the known ozone concentration (unit: ppb) is recorded, and is formed as shown in FIG. Figure.

After the correction step of FIG. 16 , in the above step S800, by alternating the gas sampling step S600 and the gas rinsing step S700, the relationship between the peak voltage and the background voltage as shown in FIG. 19 can be obtained, and the peak current can be known. The ratio of the pressure to the background voltage, and thus, according to the ratio value, corresponding to the relationship between the ratio value obtained in the above-mentioned correction step and the known ozone concentration, the ozone concentration of the gas to be tested can be derived.
