102b is provided with air vent 102e.When ozone generating apparatus 100 work, the gas containing oxygen enters anti-from air inlet 102d
Cavity 102 is answered, is excited by the irradiation of ultraviolet source 104, so as to produce ozone, then reaction cavity 102 is discharged via air vent 102e,
For the utilization of next step.For clarity of explanation, the flow direction of gas is separately depicted with arrows in FIG.
Reaction cavity 102 can be formed by arbitrary known method and arbitrary known materials, for example, its side wall
102c can be made of clear material, such as glass or quartz, it is also possible to be made of metal, and its first end face 102a and second

It, in the present embodiment, external electrode 118 is electrically connected by contacting with the first lamp tube protective cover 106 with reaction cavity 102.Extremely
Reaction cavity 102 is then passed in interior electrode 120, and reaction cavity 102 is electrically insulated.External electrode 118（And be connected electrically
Reaction cavity 102）Can be grounded（grounded）, and interior electrode 120 may be connected to high voltage source 119, thus, be able to fluorescent tube
Discharge gas 114 in 116 bestows high voltage.
First lamp tube protective cover 106 is fixed in reaction cavity 102, can receive, support and protect ultraviolet source 104,
Its material is not particularly limited, but can be in the present embodiment aluminum.First lamp tube protective cover 106 has bottom 106a and body
106b, bottom 106a and body 106b define an accommodation space 106c, and one end of ultraviolet source 104（It is in FIG the right side
End）Just it is placed in accommodation space 106c.The height of body 106b is not particularly limited, and is advisable be enough to receive ultraviolet source 104,
Certainly, if body 106b is made up of lighttight material, its height is unsuitable excessive, in order to avoid it is blinded by ultraviolet source 104

The yield of performance.Reference picture 8B, compares with comparative example 1, and because comparative example 2 employs Excimer lamp, it can be with relatively low
Power generate the suitable ozone of concentration, therefore its yield increases.As for the ozone generating apparatus of experimental example 1, due to it
Unique structure design（The particularly setting of air inlet cushion space）, its yield of ozone is even more considerably beyond comparative example 1 and 2.
Fig. 9 A and Fig. 9 B present the ozone generating apparatus of experimental example 2 and experimental example 3 operationally, the ozone concentration of generation
With the relation of time.Experiment is carried out under conditions of gas flow rate 18L/min.Experimental example 2 and experimental example 3 are all used such as figure
6 ozone generating apparatus painted.Difference part is length L of air inlet cushion space1It is different.The L of experimental example 21It is 6mm.Experiment
The L of example 31It is 0.5mm.As can be seen here, as long as air inlet cushion space is present, at least when its length is between 0.5mm and 6mm
Buffering, the effect of uniform gas distribution can be completed.
In sum, the present invention focuses on the gas flowfield design of ozone generating apparatus, and can also take into account making and group
The facility of dress, is also not required to too high cost.Present invention is designed such that extraneous gas（Such as air or purity oxygen）Equably lead to
The surface of ultraviolet source is crossed, thus, the ozone concentration for producing is at a relatively high, the ozone for solving currently used ultraviolet source produces dress
The problems such as putting making complexity, high cost, cavity and be easily broken.
Although with reference to above example, the invention has been described, however, it is not limited to the present invention.Belonging to any
