DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0030] The relative positions descried in the following embodiments, including upper, lower, left and right, unless otherwise specified, are based on the directions indicated by the components in the figures.

[0031] Refer to FIG. 1 and FIG. 2, a perspective view and an explosive view of a portable hydrogen-containing ozone water humidifier according to the present invention are revealed. The portable hydrogen-containing ozone water humidifier includes a housing 10, a water tank 20, a hydrogen-containing ozone water generator 30, an ultrasonic atomizer 40, a rechargeable battery 50 and an electronic controller 60. The housing 10 is a hollow tube provided with a mist outlet 11 on a front side while the hydrogen-containing ozone water generator 30, the ultrasonic atomizer 40, the rechargeable battery 50 and the electronic controller 60 are all mounted in the housing 10. The rechargeable battery 50 is preferably a lithium-ion battery. The present portable hydrogen-containing ozone water humidifier is designed in an upright style and the water tank 20 is arranged at the top of the housing 10. The portable hydrogen-containing ozone water humidifier is compact in volume, rechargeable and easy to carry.

[0032] The water tank 20 is for storing water while an outlet pipe 21 is connected to the bottom of the water tank 20 and enclosed in the housing 10. An inlet end 211 of the outlet pipe 21 is connected to the inside of the water tank 20. In a preferred embodiment, the water tank 20 is made from transparent materials such as plastic so that the amount of the water in the water tank 20 can be observed visually. Moreover, the water in the water tank 20 can be added with antimicrobial additives or essences to provide functions of disinfection, humidification and aroma.

[0033] As shown in FIG. 2, the water tank 20 is a bottle with an opening 22 on one end. The inlet end 211 on top of the outlet pipe 21 is connected with a tank cap 23. The outlet pipe 21 and the tank cap 23 can be made by plastic injection molding and integrated into one part. The tank cap 23 is fixed on the top of the housing 10 (such as by adhesion or ultrasonic welding). The tank cap 23 can be either connected to or separated from the opening 22 of the water tank 20. For example, a thread 24 and a sealing gasket 25 are arranged at a connection between the opening 22 and the tank cap 23 of the water tank 20. The tank cap 23 can be connected or disconnected to the opening 22 of the water tank 20 by the thread 24. Before use, water is filled into the water tank 20 through the opening 22 firstly. Then the tank cap 23 on the top of the housing 10 is connected to the opening 22 of the water tank 20. Next the opening 22 of the water tank 20 is facing downward to make water flow out through the outlet pipe 21 (as shown in FIG. 3 and FIG. 4). Now the portable hydrogen-containing ozone water humidifier can be used by the bottom of the housing 10 being placed or set on a table surface or other planes.

[0034] Refer to FIG. 5, another embodiment of the water tank 20 is revealed. The difference between this water tank 20 and the one shown in FIG. 2 is in that the water tank 20 shown in FIG. 5 includes the opening 22, the sealing gasket 25, a filling opening 26 on the other end thereof opposite to the end with the opening 22, and an upper cover 27 used for closing the filling opening 26 and located on the other end thereof opposite to the end with the opening 22. In a preferred embodiment, a thread 28 is disposed on a connection between the filling opening 26 and the upper cover 27. After the opening 22 of the water tank 20 being connected to the tank cap 23 on the top of the housing 10, water is filled into the water tank 20 through the filling opening 26. In other embodiments, the filling opening 26 is sealed by a plug instead of the upper cover 27.

[0035] Refer to FIG. 6, a further embodiment of the water tank 20 is disclosed. The water tank 20 and a mist structure thereunder can be made by plastic injection molding and integrated into one part. The mist structure consists of an outlet pipe 21 and a tank cap 23 while a filling opening 26 and an upper cover 27 are still located at the top of the water tank 20. Basically, the tank cap 23 can be considered as the inlet end 211 of the outlet pipe 21. That means the water tank 20 and the outlet pipe 21 can be made by plastic injection molding and integrated into one part. The sectional view of the one part is shown in FIG. 7. Compared with the embodiments shown in FIG. 1 and FIG. 5, the water tank 20 and the outlet pipe 21 in the embodiment shown in FIG. 6 has the simpler structure due to integration of them by plastic injection molding. There is no need to use a sealing gasket 25 so that the assembly cost is further decreased.

[0036] The hydrogen-containing ozone water generator 30 is an electrolytic hydrogen-containing ozone water generator 30 composed of an anode plate 31 and a cathode plate 32. The anode plate 31 and the cathode plate 32 are mounted in the water tank 20 for electrolysis of water in the water tank 20 to generate oxygen and ozone gas at the anode plate 31 and hydrogen gas at the cathode plate 32. Thereby disinfectant water formed by ozone water mixed with hydrogen-rich water is obtained. The anode plate 31 and the cathode plate 32 are electrically connected to electronic controller 60. The electronic controller 60 not only drives the hydrogen-containing ozone water generator 30 to work but also controls its operation time once a direct voltage/or current is applied to the anode plate 31 and the cathode plate 32. Nano-scale oxygen gas and ozone gas are produced by electrolysis of water at the anode plate 31 and ozone water is further generated. The shape of the anode plate 31 and the cathode plate 32 is not limited. For example, the anode plate 31 and the cathode plate 32 shown in the embodiment in FIG. 3 and FIG. 4 are only an exemplary configuration. The anode plate 31 and the cathode plate 32 can switch position as long as they are in close positions, their shapes are symmetrical, and the electric field generated by them is uniform. The shape of the anode plate 31 and the cathode plate 32 can be a column, a mesh, a sheet or other symmetrical shape.

[0037] In a preferred embodiment, the anode plate 31 and the cathode plate 32 are mounted in the outlet pipe 21. It should be noted that the size of the anode plate 31 and the cathode plate 32 should not block the outlet pipe 21. That means the total size of the anode plate 31 and the cathode plate 32 is not over the cross-sectional area of the outlet pipe 21. Water in the water tank 20 passes through the anode plate 31 and the cathode plate 32 while moving along the outlet pipe 21 to an outlet end of the outlet pipe 21. During electrolysis, water is oxidized at the anode plate 31 to get oxygen gas and ozone gas while hydrogen gas is generated at the cathode plate 32. Thereby disinfectant water formed by ozone water mixed with hydrogen-rich water is obtained.

[0038] Moreover, the anode plate 31 is preferably to be made of active electrode materials with anti-oxidative activity including platinum, stainless steel, titanium, insoluble anode materials (such as dimensionally stable anode (DSA)), graphite/or graphene, doped and undoped oxides (such as RuO2, IrO2, PbO2, SnO2, TiO2, etc.), nitrogen-doped or boron-doped diamond, or their combinations. As to the cathode plate 32, it is preferably made of platinum, stainless steel, titanium, stainless steel with a coating that promotes hydrogen generation (such as platinum), titanium with a coating that promotes hydrogen generation (such as platinum), graphite/or graphene, or their combinations. In a preferred embodiment, the anode plate 31 includes a stainless steel electrode coated with the active electrode materials with anti-oxidative activity mentioned above, a titanium electrode coated with the active electrode materials with anti-oxidative activity mentioned above, a graphite electrode or a graphene electrode.

[0039] The ultrasonic atomizer 40 is arranged at the outlet end of the outlet pipe 21. For example, the ultrasonic atomizer 40 is adhered on the outlet end of the outlet pipe 21 by waterproof adhesive. The ultrasonic atomizer 40 basically consists of a piezoelectric ceramic plate 41, a micro-hole perforated metal sheet 42 attached to a ring-shaped piezoelectric ceramic plate 41 to form a composite, and an outlet port 43 which is a central hole of the piezoelectric ceramic plate 41. The micro-hole perforated metal sheet 42 has micro holes aligned with the outlet port 43 of the ultrasonic atomizer 40 while the outlet port 43 is connected to the mist outlet 11 so that the disinfectant water mentioned above is atomized into hydrogen-containing ozone water mist by the micro-hole perforated metal sheet 42 of the ultrasonic atomizer 40 and then passed through the micro holes and the mist outlet 11 to be sprayed out.

[0040] In a preferred embodiment, a tapered tube 44 (as shown in FIG. 3) is disposed on the outlet port 43 of the ultrasonic atomizer 40. The tapered tube 44 which has an entrance and an exit is tapered from the exit to the entrance. The outlet port 43 of the ultrasonic atomizer 40 is connected to the entrance of the tapered tube 44 while the exit of the tapered tube 44 is connected to the mist outlet 11. The hydrogen-containing ozone water mist is first passed through the tapered tube 44 and then sprayed out through the mist outlet 11 so that the hydrogen-containing ozone water mist is more concentrated and sprayed out a further distance, as shown in FIG. 7.

[0041] As shown in FIG. 2, FIG. 3, FIG. 6 and FIG. 7, the electronic controller 60 is electrically connected to the hydrogen-containing ozone water generator 30, the ultrasonic atomizer 40, and the rechargeable battery 50. The rechargeable battery 50 provides power to the electronic controller 60, the hydrogen-containing ozone water generator 30, and the ultrasonic atomizer 40. The electronic controller 60 consists of a control circuit 61, a power on/off switch 62 and an electrical connector 63. The control circuit 61 is electrically connected to the power on/off switch 62, the electrical connector 63, the rechargeable battery 50, the anode plate 31 and the cathode plate 32 of the electrolytic hydrogen-containing ozone water generator 30, and the piezoelectric ceramic plate 41 of the ultrasonic atomizer 40. In the housing 10, an insertion port of the electrical connector 63 is exposed while the control circuit 61 can be electrically connected to an external power source by the electrical connector 63 for charging the rechargeable battery 50. The control circuit 61 which gets power from the rechargeable battery 50 drives the hydrogen-containing ozone water generator 30 and the ultrasonic atomizer 40 to work and controls the operation time. The power on/off switch 62 can be a push-type electrical component. A button 12 is disposed on the front side of the housing 10 and a front surface of the button 12 is exposed. While in use, the button 12 is pressed for driving the power on/off switch 62 to turn on or turn off the control circuit 61, the hydrogen-containing ozone water generator 30, and the ultrasonic atomizer 40.
