Detailed Description

The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.

The not enough to current STREAMING dark ultraviolet sterilizing equipment, the utility model provides a STREAMING dark ultraviolet sterilizing equipment, its dark ultraviolet irradiation's high-usage, and the deep ultraviolet is comprehensive to shining of water, does not have the dead angle, consequently, the bactericidal ability is strong.

Fig. 1 shows a cross-sectional view of the over-flow type deep ultraviolet sterilization device of the present invention. As shown in fig. 1, the over-flow type deep ultraviolet sterilizer of the present invention includes a housing 1, similar to the existing over-flow type deep ultraviolet sterilizer. The water inlet end of the shell 1 is connected with a water inlet connector 2, and the water outlet end of the shell is connected with a water outlet connector 3. Water W flows into the housing 1 from the water inlet joint 2 and flows out of the housing 1 from the water outlet joint 3.

Wherein, the shell 1 is internally provided with a deep ultraviolet LED4 and a side wall water spraying plug 5. The deep ultraviolet LED4 is arranged near the water inlet end of the shell 1. The deep ultraviolet LED4 is used for emitting deep ultraviolet light so as to sterilize the water 2 flowing through the housing 1 by the deep ultraviolet light.

Preferably, the deep ultraviolet LED4 has a plurality thereof to improve sterilization capability thereof.

More preferably, the deep ultraviolet LED4 has an emission wavelength of 265nm to 280nm and an emission angle of 30 °. In this way, it can better sterilize the water flowing through the flow-through type deep ultraviolet sterilization device.

The side wall water spraying plug 5 is of a hollow structure, the end face of one end of the side wall water spraying plug is close to the deep ultraviolet LED4, and the side face of one end of the side wall water spraying plug is provided with a plurality of water spraying ports 6.

Preferably, the diameter of one end of the side wall water spraying plug 5 is smaller than that of the other end, and the outer wall of the other end is tightly attached to the inner wall of the shell 1.

Thus, the water W flowing into the housing 1 from the water inlet joint 2 is stopped by the other end of the side wall water spray plug 5 and enters the side wall water spray plug 5 through the water spray port 6. When water flows pass through the water spraying ports 6 of the side wall water spraying plugs 5, water flow channels are formed, the water flows are irradiated by the deep ultraviolet light emitted by the deep ultraviolet LEDs 4 at the moment of passing through, and due to the fact that the water flow channels are formed, all the passing water flows are irradiated by the deep ultraviolet light emitted by the deep ultraviolet LEDs 4, the irradiation dead corners are avoided. Compared with the prior art that the channel of the internal water flow is designed to be a straight-through type, the irradiation effect is better.

Preferably, quartz glass 7 is arranged between the deep ultraviolet LED4 and the end face of one end of the side wall water spraying plug 5. The quartz glass 7 can prevent the water in the side wall water spraying plug 5 from causing adverse effects on the deep ultraviolet LED 4.

More preferably, a heat sink 8 is further provided in the housing 1. The cooling fin 8 is installed the lamp plate back of deep ultraviolet LED4, from this, deep ultraviolet LED 4's lamp plate relies on rivers to pass through cooling fin 8 dispels the heat.

In addition, in the present invention, an inner lining tube 9 made of teflon material is further disposed in the housing 1. One end of the lining pipe 9 is connected with the other end of the side wall water spraying plug 5, and the outer wall of the lining pipe 9 is tightly attached to the inner wall of the shell 1. Thus, water flowing out from the other end of the side wall water-spraying plug 5 enters the lining pipe 9.

And a water outlet plug 10 made of Teflon material is also arranged in the shell 1. Wherein, the water outlet plug 10 is located at the inner side of the water outlet end of the outer shell 1, and one end of the water outlet plug is adjacent to the other end of the lining tube 9.

And the diameter of the water outlet plug 10 is smaller than the inner diameter of the lining pipe 9.

Because the lining pipe 9 and the water outlet plug 10 are made of Teflon materials, the reflectivity of the lining pipe to deep ultraviolet rays is high.

Thus, in the normal working state of the deep ultraviolet LED4, when the water W flows into the side wall water spraying plug 5 through the water spraying port 6 of the side wall water spraying plug 5, the water W is completely irradiated by the deep ultraviolet light. In addition, in the irradiation process, the water outlet plug 10 on the water outlet end face and the inner wall of the lining pipe 9 are also subjected to deep ultraviolet reflection at the same time. The design ensures the comprehensive irradiation sterilization of water flow and the uniformity, penetrability and reflectivity of the illumination in the sterilization cavity, and finally realizes the purpose of high-efficiency sterilization of the overflowing type deep ultraviolet sterilization device.
