The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
Shown in attached Fig. 1 and 2, a kind of water dispenser photocatalysis gas phase device, it comprises the photocatalysis pottery sheet 1 of the central openings that is no less than a slice, photocatalysis pottery sheet 1 builds up cylindrical drum 3 by 2 groups of screw rods, screw rod 2 is positioned at photocatalysis pottery sheet 1 outer face and locks with nut 4, screw rod 2 two ends are separately fixed on the upper cover plate 5 upper and lower cover plates 6, separated by packing ring 7 between the photocatalysis pottery sheet 1 and form gas-phase photocatalysis reactive tank 8, cylindrical drum 3 central hollow places arrange ultraviolet lamp 9, ultraviolet lamp 9 lower ends are passed lower cover 6 and are fixed on the lamp socket 10, cylindrical drum 3 periphery covers have the sponge 11 of filtration, filter sponge 11 and be in impaction state, upper cover plate 5 centers are provided with gas outlet 501, gas outlet 501 is communicated with photocatalytic reaction tank 8 by all gaps 901 of the lamp around the ultraviolet lamp 9, lower cover 6 is fixed on the base 12, and ballast 13 and pressure-sensitive switch circuit 14 are housed in the base 12.
