Taking NaOH liquid as one example of the first fluid F1, when the power source S provide electrical power to electrode device2, the hydrogen ions H+move toward the cathode thereby generating hydrogen while, at the same time, the oxygen ions O2−move toward the anode for generating oxygen. The accumulation of the oxygen and hydrogen generated form the electrolytic reaction will form the bubbles respectively attached onto the first and second plates20and21. Conventionally, the bubbles associated with the electrolytic gases will hider the process of the electrolytic reaction.

Please refer to theFIG.3B, which illustrates an electrolytic device according to another embodiment of the present invention. Basically, the electrolytic device3iis similar to the electrode device shown inFIG.3A, the different part is that the electrode device utilized herein is the electrode device2eshown inFIG.1C. Unlike the electrode device2having two opposite first plate20and second plate21shown inFIG.3A, the electrode device2eutilized single second plate21having a first electrode24aand a second electrode24bformed on the second plate21corresponding to the first flow channel220defined by the two adjacent isolation structures221a, wherein the first electrode24ais positive electrode and the second electrode24bis negative electrode. In the present embodiment, the first and second electrodes24aand24bare respectively the cycloid structures embedded into the second plate21. It is noted that the profile of the first and second electrodes24aand24bare not limited to the cycloid shape. For example, alternatively, the first and second electrodes24aand24bcan be a straight bar structures. In addition, it is not limited to a single pair of the first and second electrodes24aand24bformed on or in the second plate21corresponding to each first flow channel220. In another embodiment, a plurality pairs of first and second electrodes24aand24bare formed on or in the second plate21corresponding to the first flow channel220. In the embodiment shown inFIG.3B, since the first electrode24aand the second electrode24bare formed on the same plane of the second plate21, the distance therebetween can be shortened and the intensity of the electrical field can be increased thereby improving the electrolytic efficiency of the electrolytic reason and increasing the production of the micro bubbles such that the micro bubbles contained in the third fluid F3exhausting from the electrode device3ican be increased.

Please refer toFIG.4Awhich illustrates an electrolytic device according to another embodiment of the present invention. Basically the electrolytic device3ais similar to the device shown inFIG.3A, the different part is that the bubble quantity can be increased whereby the micro bubbles in the third fluid F3are further increased. In the preset embodiment, a first hollow channel311is formed inside the rotating shaft31for guiding the second fluid F2. In the present embodiment, the second fluid F2is a gas which can be, but should not be limited to, air, oxygen, carbon dioxide or ozone. The second fluid F2enters into the first hollow channel311from a terminal opening312of the first hollow channel311.

A gas supplier34is arranged on one end of the rotating shaft31. The gas supplier34further comprises an engaging element340and a porous plate343. The engaging element340further comprises a guiding channel341formed inside the engaging element340, wherein one end of the guiding channel341is connected to the porous plate343while the other end of the guiding channel341is communicated with the first hollow channel311such that the second fluid F2flowing into the first hollow channel311can be guided into the guiding channel341. The second fluid F2inside the guiding channel341then enters the first flow channel220of the electrode device2through the porous plate343. In the present embodiment, the axial direction of the guiding channel341is the same as the axial direction of the first hollow channel311. In the present embodiment, the engaging element340is connected to the rotating shaft31though the threads formed on the peripheral of the engaging element340.

The porous plate343is fixed by the engaging element340. In the present embodiment, one surface of the porous plate341is secured by one end of the engaging element340while the other surface is leaned against the rotating shaft31so that the porous plate343can be fixed onto the rotating shaft31by the engaging element340. The porous plate343is connected to the guiding channel341for receiving the second fluid F2. In the present embodiment, the engaging element340is communicated with the porous plate343for receiving the second fluid F2through a sub flow channel342. It is noted that, the way that making the engaging element340communicate with the porous plate343is not limited to the embodiments shown in the figures. The one having ordinary skilled in the art can selecting proper ways to make the engaging element430communicate with the porous plate343according to the user need. In the present embodiment, the porous plate343is arranged inside the inlet opening35. When the engaging element340is engaged with the end of the rotating shaft31, a gap G is formed between the porous plate343and the inner wall of the inlet opening35for allowing the first fluid F1enters into the electrode device2, wherein the second fluid F2enters into the sub flow channel342through the first hollow channel311and guiding channel341, the second fluid F2further enters the porous plate343through the sub flow channel342and then is exhausted from the peripheral of the porous plate343.

Simultaneously, the second fluid F2can be drawn into the first hollow channel311inside the rotating shaft31due to the negative pressure generated by the rotation R1. The second fluid F2then enters the porous plate343. Since the porous plate343is engaged with the rotating shaft31, when rotating shaft31is rotated, the porous plate343is rotated to generate the centrifugal force. The farer distance away from the center of the porous plate343it is, the larger the centrifugal force it becomes. Due to the centrifugal force generated by the porous plate343, the second fluid F2can be exhausted from the porous plate343through the lateral surface along the axial direction. The second fluid F2exhausted from the porous plate343is then cut by the first fluid F1passing through the gap G whereby the second fluid F2is physically transformed into a plurality of micro bubbles. The micro bubbles mixed with the first fluid F1enters the electrode device2, and then the first fluid F1with the plurality of micro bubbles enters the plurality of first flow channels220and is exhausted out of the electrode device2through the centrifugal force generated by the rotation of the electrode device2. The mixture of micro bubbles and the first fluid F1forms the third fluid F3and the third fluid F3is exhausted out of the housing30from the exhausting opening360of the exhausting part36.

Please refer toFIG.4B, which illustrates an electrolytic device according to another embodiment of the present invention. In the present embodiment, the electrolytic device3his basically similar to the embodiment shown inFIG.4A. The different part is that the electrode device2efurther comprises a gas channel28which passes through the second plate21, isolation part22, and the first plate20, and finally communicates with the flow inlet201. In the present embodiment, one end of the gas channel28is formed inside the second plate21and is communicated with the first hollow channel311such that the second fluid F2inside the first hollow channel311can flow into the gas channel. It is noted that although the architecture shown inFIG.4Acomparing with the embodiment shown inFIG.3Acan further increase the quantity of micro bubbles contained within the first fluid F1, the gap G is spatially limited between the porous plate343and the flow inlet201so that the first fluid F1enters the electrode device2will be reduced due to the resistance generated from the insufficient space of gap G thereby affecting the quantity of the micro bubbles formed by the second fluid F2. However, in the embodiment shown inFIG.4B, a plurality through holes280formed around the wall defining the flow inlet201can be communicated with the gas channel28so that the gas channel28can communicate with the flow inlet thereby reducing the resistance between the first fluid F1and the second fluid F2. Therefore, the quantity of micro bubbles contained in the first fluid F1can be effectively increased.

Next, the operation of the embodiment shown inFIG.4Bis explained. When the electrode device2eis rotated through the driving of the rotating shaft31, the second fluid F2can be drawn into the first hollow channel311formed inside the rotating shaft31. The second fluid F2further enters the gas channel28. Since the gas channel28is communicated with the flow inlet201, when the rotating shaft31is rotated, the drawn second fluid F2inside the gas channel28is exhausted from the through holes280. The exhausted second fluid F2is cut by the first fluid F1drawn from the inlet opening35so as to form a plurality of micro bubbles. The micro bubbles are then mixed with the first fluid F1so as to form the third fluid F3entering the electrode device2e. Since the electrode device e2is also rotated, the centrifugal force generated by the rotation of electrode device2epushes the third fluid F3out of the electrode device2ethrough the first flow channel220. The third fluid F3is then exhausted out of the housing30from the exhausting opening360of the exhausted part36. It is noted that since the first fluid F1can cut the second fluid F2into the micro bubbles in the flow inlet201in advance, and the third fluid F3inside the electrode device2ecan also have electrolytic reaction with the electrode device2ethereby generating hydrogen bubbles and oxygen bubbles, the micro bubbles in the third fluid F3are greatly increased because it contains the micro bubbles originated from the second fluid F2and oxygen bubbles and hydrogen bubbles generated by the electrolytic reaction. Accordingly, the electrolytic device3hcomparing with the device shown inFIG.3A,3B or4A, can greatly improve the quantity of micro bubbles.
