The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
Please refer to Fig. 1, this Figure 1 shows that the blast structural representation of an embodiment of this utility model Portable circulation wind air sterilizer.
As shown in Figure 1, the Portable circulation wind air sterilizer of this embodiment includes the housing of lower casing 1 and upper casing 16 formations, be provided with trim 17 on upper casing 16, form air inlet between upper casing 16 and trim 17, be formed with air outlet in lower casing 1 rear end, and housing and upper cover 17 space that surrounds forms the air channel of whole steriliser.
In housing and upper cover 17 formed air channel, be disposed with deep ultraviolet LED sterili-sation unit, air filter unit and fan 2 from the air inlet to the air outlet.
Wherein, deep ultraviolet LED sterili-sation unit includes circuit board support 11, and 11 are disposed with main control board 15, deep ultraviolet LED circuit plate 14, LED sealing ring 13 and quartz glass 12 from upper cover 17 to air filter unit direction on circuit board support.Wherein, deep ultraviolet LED circuit plate 14 seals by LED sealing ring 13 and quartz glass 12, forms annular seal space.Deep ultraviolet LED in deep ultraviolet LED circuit plate 14 is positioned at the sealing intracavity and arranges towards air filter unit, makes the hot spot of the DUV that LED sends towards drainage screen, is convenient to kill antibacterial in the dust that is attached on drainage screen with the strongest light.Utilize quartz glass 12 and deep ultraviolet LED circuit plate 14 formed annular seal spaces that deep ultraviolet LED sealing is installed, avoid airborne aqueous vapor to enter on deep ultraviolet LED circuit plate and affect the service behaviour of LED.And, because 12 pairs of deep ultraviolet light permeabilitys of quartz glass are good, can not affect its irradiation-sterilize performance.
Except adopting quartz glass consists of annular seal space, also can adopt other transparent glass that can see through deep UV to realize, this embodiment does not do concrete restriction to this.
Air filter unit includes the filtering frame that lower filtering frame 5 and upper filtering frame 9 consist of, and the direction from deep ultraviolet LED sterili-sation unit to fan 2 on filtering frame is disposed with drainage screen 8, shelf 7 and wire netting 6.Drainage screen 8 as filtered air, receive the critical component of antibacterial, near deep ultraviolet LED circuit plate 14 and arranging.The preferred wire netting that adopts surface-coated that titanium dioxide is arranged of wire netting 6 is played a supporting role to drainage screen 8 on the one hand, and on the other hand, this wire netting is difficult for saving bit by bit dust, has reduced growing of antibacterial; And, can also utilize the titanium dioxide on it to carry out re-pasteurization, further improve germicidal efficiency.And between drainage screen 8 and wire netting 6 that shelf 7 arranges, drainage screen 8 and wire netting 6 are separated, puncture drainage screen 8 to prevent sharp-pointed wire netting 6, be conducive to simultaneously the disassembling, assembling and replacing of drainage screen 8.
In this embodiment, the air filter unit of said structure and deep ultraviolet LED sterili-sation unit first are arranged on the fixed support that lower fixed support 4 and upper fixed support 10 consist of, and then seal by the fan 2 on the lower casing 1 of fan sealing gasket 3 and installation, to strengthen the sealing in the inner air channel of steriliser, improve the circulated air air quantity, improve the germicidal efficiency of air sterilizer.
In addition, in this embodiment, go back display lamp 18 on trim 17, this display lamp 18 is connected with main control board 15, and the deep ultraviolet LED in steriliser will glimmer when working, and extinguish when deep ultraviolet LED quits work.Therefore, can be used as the status indicator lamp that deep ultraviolet LED duty is indicated, be convenient to the duty that user is known air sterilizer.And in this embodiment, trim 17 is designed to the lamp affixed to the ceiling character, and display lamp 18 is designed to the arc-shaped lamp strip, divides two sections and is arranged on trim 17.
The air sterilizer of said structure can adopt following process to carry out the assembling of each parts:
The first step, assembling air filter unit: wire netting 6, shelf 7 and drainage screen 8 are successively placed on lower filtering frame 5; Then, upper filtering frame 9 is pushed down wire netting 6, shelf 7 and drainage screen 8, and snap together by buckle and lower filtering frame 5.
Second step, assembling air filter unit and deep ultraviolet LED sterili-sation unit: upper fixed support 10 is placed on lower fixed support 4; Then, circuit board support 11 is pushed down upper fixed support 10, and fixing by snap fit and lower fixed support 4; Then, place successively quartz glass 12, LED sealing ring 13 on circuit board support 11; Again deep ultraviolet LED circuit plate 14 is pushed down LED sealing ring 13 and 12 quartz glasss, and fixing by screw and circuit board support 11; Then main control board 15 is screwed on circuit board support 11.At last, the air filter unit that the first step is assembled injects in upper fixed support 10 and the formed fixed support of lower fixed support 4.
The 3rd step, upper casing assembling: display lamp 18 is inserted on trim 17, then the trim 17 that assembles is inserted on upper casing 16.
The 4th step, general assembly: fan 2, fan sealing gasket 3 are placed on lower casing 1, the structure that second step assembles are pushed down fan sealing gasket 3 and fan 2, and be screwed on lower casing 1; At last, the upper casing 16 and the lower casing 1 that assemble are clamped, complete the assembling of whole air sterilizer.
The groundwork process of the air filter of this embodiment is as follows: switch on power, air sterilizer is started working, and fan 2 rotates, the air of outside is pumped in steriliser, and dirty blows air over drainage screen 8, antibacterial and dust adhesion are on drainage screen 8.Deep ultraviolet LED sends ultraviolet light, and the antibacterial on irradiation drainage screen 8 kills antibacterial, reaches the effect of air sterilization.After sterilization, pure air after wire netting 6 carries out re-pasteurization, blows out from air outlet.In sealed environment, air circulation flows, and the relative pure air that blows out from steriliser can be drawn into steriliser again, proceeds sterilization.Like this, through repeatedly sterilization, can guarantee finally that the circulating air in environment is clean, pure and fresh.In the air sterilizer work process, display lamp 18 glimmers under the control of the governor circuit on main control board 15, and the indication steriliser is in the sterilization operation state.Deenergization, air sterilizer quits work, and display lamp extinguishes.
Above embodiment is only in order to illustrating the technical solution of the utility model, but not is limited; Although with reference to previous embodiment, this utility model is had been described in detail, for the person of ordinary skill of the art, still can modify to the technical scheme that previous embodiment is put down in writing, perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of this utility model technical scheme required for protection.
