First, the watertight structure irradiating hole 11 periphery installation and the window component protection structure at the first shell 10 is examined
Look into.With reference to Fig. 1, Fig. 2 and Fig. 8, at the inner surface of the first shell 10, it is provided with around the circular square shape irradiating hole 11
Window component receiving portion 12.And, around window component receiving portion 12, it is formed and is inserted in window component receiving portion 12 for preventing
Window component 40 stage portion 13 travelling to side.The height of stage portion 13 is contained in window component receiving portion 12 at window component 40
Under state, the height with window component 40 is substantially the same.If their height is substantially the same, then at window component 40 and step
Portion 13 above does not has a step difference, thus can to cover window component (aftermentioned with the hermetic unit on stage portion border only by putting
An O ring) and make the structure being adjacent to, just can easily embody sealing.
The material that the deep UV that window component 40 irradiates as aftermentioned ultraviolet LED can pass through, can be stone
English or quartz glass (fused silica).
With reference to Fig. 2, Fig. 3 and Fig. 8, be inserted in the window component 40 of window component receiving portion 12 with in stage portion 13, be placed with to
Cover an O ring 50 of gap portion between window component and stage portion less.Oneth O ring 50 is annular shape, and its outer peripheral face 51 is big
In the periphery of window component 40 and/or the medial surface of stage portion, inner circumferential surface 52 is less than window component 40 (with reference to Figure 10).Therefore, as
Fruit is placed on an O ring 50 in the window component 40 and the stage portion 13 that are inserted in window component receiving portion 12, then window component and stage portion
Between gap portion blocked by an O ring 50.
In the outside at the position placing an O ring 50, it is formed with the first of the position limiting an O ring 50 as shown in the figure
Rib 14.It addition, in the outside of the first rib 14, it is provided with the 2nd O ring holding tank 16 inserted for the 2nd O ring 56, and the
Two O ring holding tank 16 outsides, are formed and have and the second rib 15 of the first rib 14 substantially the same height.Hold at the 2nd O ring
Receiving and accommodate the 2nd O ring in groove 16, this utility model is setting as described above on the path that the probability of the infiltration realizing water is high
Put two stage sealing structure so that can be the most waterproof.Especially, when digonous 14 and 15 highly consistent time, the most more
Easily accommodate the 2nd O ring, and when pressing attached parts pressing the 2nd O ring, it presses attached power not bias toward certain side, so that the
Two O rings expand equably.
With reference to Fig. 3, Fig. 4 and Fig. 8, an O ring 50 and the 2nd O ring 56 are provided with the attached parts 60 of pressure.As it can be seen, pressure
Attached parts 60 are formed with circular hole 62 as the writing board shape of annular at central part, and are formed for adding in outside surrounding
Suppress the rib 61 of the rigidity of attached parts 60.It addition, be formed with 3 fastening parts 66 by 120 degree of intervals.Fastening part 66 makes to fasten spiral shell
Silk (not shown) is through, and the screw of through fastening part 66 is incorporated into the inner surface of the first shell threadably, thus presses
Attached parts 60 strength presses the attached inner surface being fixed on the first shell 10.
The attached power of this pressure passes to O ring 50 and a 2nd O ring 56, therefore, the above and attached parts 60 of pressure of an O ring
It is adjacent to below, is adjacent to the above of window component 40 and the above of stage portion 13 below an O ring.If an O ring 50 is pressed
Attached, then by means of its pressure, an O ring 50 is pressed, the side that the outer peripheral face 51 of an O ring 50 to increase further to its diameter
To expansion, inner peripheral surface 52 to expand to the direction that its diameter reduces further.The outer peripheral face 51 of a this O ring 50 is because expanding quilt
First rib 14 stops and is mutually adjacent to.On the other hand, the expansion of the inner peripheral surface of an O ring 50 is by from the hole 62 4 pressing attached parts 60
Circumference window component direction, i.e. the protrusion rib 64 of the form protruded downwards stops.Now, protrude rib 64 bottom not with window
Parts 40 contact, and are formed with the gap of predetermined space relative to window component.If protruding rib 64 to contact with window component 40, then exist
Window component 40 is protruding the pressure and the probability of breakage concentrated at rib 64 position, therefore, between window component and protrusion rib,
Require predetermined interval.On the other hand, without protruding rib 64, then the inner peripheral surface of an O ring 50 freely expands to inner side,
Thus the power that is adjacent near the inner peripheral surface of an O ring 50 and between compression member and window component declines.Therefore, rib 64 is protruded best
Consider the material etc. of an O ring, even if not apply the pressure concentrated to window component, also can between window component and an O ring
Enough height being adjacent to uniform pressure are formed.If more protruded lower it is to say, protrude rib, do not execute to window component
The probability adding focus pressure is the highest, on the contrary, if the uniformity of the pressure put between window component and an O ring more under
Fall, protrudes rib and more forms protrusion higher, then the probability to window component applying focus pressure is the highest, but more it is advantageously ensured that and execute
The uniformity of the pressure being added between window component and an O ring.Protrude rib protrusion height can consider an O ring material and
Protrude the gap between rib and window component etc. and determine optimum height so that meet described condition.
The area of section of the 2nd O ring 56 arrange than by means of the 2nd O ring holding tank 16 and first rib the 14, second rib 15 and
The area of section pressing attached parts and formed is slightly larger, and when pressing attached parts to press attached 2nd O ring, the outside of the 2nd O ring is with uniform pressure
Power is adjacent to the 2nd O ring holding tank 16 and first rib the 14, second rib 15 and presses attached parts.
For in theory, in the silica gel material with 0～100 hardness, an O ring 50 is flexible with have less than 30
Silica gel material makes.This allows in the case of hardness is more than 30, when utilizing the attached parts of pressure to press an attached O ring, concentrates
Pressure put on the specific part of window component 40 and cause the probability of breakage high.Certainly, attached parts are pressed can to use hardness
Higher than the material of an O ring, such as ABS resin etc..
As shown in Figure 9 B, between window component 40 and window component receiving portion 12, it is also possible to be equipped with extra elastomeric element (or
Claim elastomeric material) 59.This eliminates between window component and window component receiving portion, and pressure concentrates on the probability of specific part,
The effect of water seal can be improved further due to being adjacent to power of elastomeric material.
On the other hand, the center in hole 62 pressing attached parts 60 is mutually aligned with the irradiation hole 11 of the first shell 10.It addition, pressure
The hole 62 of attached parts 60 and the shape irradiating hole 11 of the first shell 10 are circle.The inner peripheral surface of the oneth O ring 50 also with they
Center consistent, shape also be circle.This is for the light-emitting diodes with the form irradiation to diffuse into cone from point source
The illumination mode of pipe is corresponding so that press pressure attached power stepless action between attached parts 60 and the first shell 10 in an O ring 50 with
Between window component 40, window component 40 is exposed to the area of outside and realizes minimizing, meanwhile, also for guaranteeing ultraviolet to greatest extent
The region that line irradiates.
On the contrary, window component 40 can be constituted with square.If being constituted window component with square, then make the making of window component
Easily, and, when limiting the position of window component by means of stage portion 13, not only limit the window component movement to side, also
Can together limit window component to rotate in position.This window component 40 and the shape of an O ring 50, the most relevant to Figure 10
Be illustrated.
Below, with reference to Fig. 4, Fig. 5, Fig. 8 and Fig. 9 A and Fig. 9 B, it is fixed with substrate 70 pressing on attached parts 60.Substrate 70 exists
On the basis of the center of substrate opposite each other 2 at position equipped with fixed part 76, the fastening screw of through fixed part 76 is with spiral shell
Stricture of vagina mode is incorporated at the fixed part 68 pressing attached parts 60 to be equipped with.The position of fixed part 68 can be provided to not with press attached parts 60
The position of fastening part 66 location overlap.
On substrate 70, towards the position irradiating center, hole 11 and Kong62Qie Qi with irradiate hole 11 and align in hole 62, patch
Equipped with ultraviolet LED 72.As an example, the illumination angle of ultraviolet LED 72 can be 120 degree.Purple
The ultraviolet that outside line light emitting diode 72 irradiates, through window component 40, penetrates towards the outside through irradiation hole 11.Thus, outside first
Shell 10 towards sterilization region be exposed to ultraviolet.
In order to guarantee the illumination angle of ultraviolet LED to greatest extent, irradiate hole 11 and can have the most laterally that it cuts open
The irradiation bore expansion portion 121 (with reference to Fig. 9 A and Fig. 9 B) that face more gradually broadens.Irradiating bore expansion portion 121 both can be as shown in Figure 9 A
For curved-surface shape, it is also possible to as shown in Figure 9 B for taper form.Regardless of its shape, irradiate bore expansion portion 121 and ultraviolet
The ultraviolet irradiation angle that light emitting diode irradiates is corresponding, guarantees irradiation area α to greatest extent, and correspondingly guarantees to support window
The area of parts 40.Without irradiating bore expansion portion 121, then in order to irradiation area is widened by α, need correspondingly to strengthen photograph
The diameter of perforation 11, therefore, it is thus achieved that make the result that the area of the window component receiving portion of support window component reduces.It addition, with photograph
The diameter of perforation 11 increases correspondingly, and (diameter pressing the hole of attached parts is little to press the diameter in the hole 62 of attached parts 60 to be also required to increase
In time irradiating the diameter in hole, occur unbalanced executing stressed area to window component the most respectively, which increase window component
Damaged probability), this makes the most unsupported window component 40 area increase, and makes the damaged probability of window component enter
One step improves.On the contrary, as shown in this utility model, irradiate bore expansion portion 121 if formed, then can guarantee purple to greatest extent
The damaged probability of window component is reduced further while the irradiation area of outside line.
