Detailed Description

The practice and use of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. The terms left, right, bottom, top, etc. used in describing the various components are not absolute, but relative. When the respective components are arranged as shown in the drawings, these representations are appropriate, but when the positions of the respective components in the drawings are changed, these representations are also changed accordingly.

Embodiments of the present invention may be applied to any suitable ultraviolet fluid treatment apparatus or device, and will be described hereinafter with reference to application to an over-flow type ultraviolet fluid treatment apparatus as an example.

Fig. 1 shows a schematic structural view of a fluid processing device according to an embodiment of the present invention. The fluid treatment device 10 includes a housing 11, an illumination assembly 12, and a flow diversion member 13. Wherein the housing 11 defines a fluid inlet 111, a fluid outlet 112, and a fluid passage communicating the fluid inlet 111 and the fluid outlet 112. In the present embodiment, the housing 11 is a square cylinder, and the space utilization rate of the housing in the application environment is better, and the housing does not roll, and the installation is more convenient. The housing 11 protects the internal structure of the device 10 and may consist of a tightly riveted upper housing 113 and lower housing 114. Both the fluid inlet 111 and the fluid outlet 112 are provided on the upper housing 113.

An illumination assembly 12 of the fluid treatment device 10 is disposed within the housing 11 and is configured to emit ultraviolet light to illuminate the fluid flowing through the fluid channel. For example, the irradiation assembly 12 may be an ultraviolet LED lamp which is disposed at the bottom inside the lower housing 114 and irradiates UVC (short wave ultraviolet) to the fluid for sterilization and purification. In one example, a quartz plate 121 capable of transmitting ultraviolet rays is disposed on the top of the illumination assembly 12, which can protect the illumination assembly 12 from water while ensuring the illumination assembly 12 illuminates normally. The long-term irradiation of the ultraviolet lamp can cause excessive heat to be accumulated in the device, resulting in the temperature rise of the device, so that the housing 11 and the metal part of the ultraviolet lamp can be made of aluminum, which helps to dissipate heat and prolong the service life of the sterilization device.

The flow dividing member 13 of the fluid treatment device 10 is arranged within the fluid passage, the flow dividing member 13 comprises a plurality of flow holes 131 therethrough, such that the fluid from the fluid inlet 111 flows out to the fluid outlet 112 through the flow holes 131 of the flow dividing member 13, wherein a side of the flow dividing member 13 facing the illumination assembly 12 is provided with a reflective portion 132, the reflective portion 132 being configured to at least partially reflect the ultraviolet light from the illumination assembly 12.

Fig. 3 shows a schematic structural view of the flow dividing member 13 in the present embodiment. In fig. 3, the flow dividing member 13 is an annular plate, and a plurality of circular flow holes 131 are circumferentially distributed at equal intervals. It should be noted that the shape of the flow dividing member 13 is not limited to a ring shape, and may be any other suitable shape. The flow dividing member 13 is not limited to a flat sheet shape, and may be in a bowl shape, a groove shape, or the like. The shape of the flow holes 131 is not limited to a circle, but may be any other suitable polygon. The plurality of flow holes 131 are not limited to being arranged in a circle, but may be arranged in a rectangular, equilateral triangle, and is not limited to a circle. The sum of the cross-sectional areas of the plurality of circulation holes 131 is greater than or equal to the cross-sectional area of the fluid inlet 111, thereby ensuring smooth flow of the fluid. In use, the flow dividing member 13 dampens high velocity fluid entering from the fluid inlet 111 while directing the water to be dispersed. This allows fluid entering through the fluid passage 101 to temporarily reside in the fluid passage 102 in the annular chamber, to flow through the flow openings 131 of the flow dividing member 13 into the fluid passage 103 and finally to the fluid outlet 112. The presence of the splitter 13 allows the right half of the annular chamber to be utilised, in effect extending the flow path of the fluid, and also allows the flow of water through the splitter 13 to be spread, the flow rate to be slowed down, the flow to be uniform and stable, and the time for the fluid to flow through the apparatus 10 to be increased.

Moreover, in the present embodiment, the reflective portion of the flow dividing member 13 is the bottom surface 132 of the flow dividing member 13, which is made of a mirror-surface stainless steel material, such as food-grade 304 stainless steel, for reflecting the ultraviolet rays in the flow channel, so as to improve the utilization rate of the ultraviolet rays and the sterilization effect of the device. The reflection part 132 may be implemented by coating a reflection material or as a separate reflection member, in addition to using a mirror material. Further, in actual use, a portion of the upper case 113 is made of plastic. The diversion member 13 with the reflection portion 132 can protect the plastic upper shell 113 from the ultraviolet radiation, so as to prevent the harmful substances precipitated after the plastic is irradiated from polluting the water body.

The fluid treatment device 10 further includes a reflective member 14 disposed adjacent an inner wall of the housing 11 and configured to at least partially reflect ultraviolet light within the flow channel. In this example, the reflective member 14 is arranged to nest in the inner wall of the housing 11. As shown in fig. 1, the reflection member 14 is installed in the lower case 114, which may be cylindrical. The reflection member 14 is spaced apart from the lower case 114 at a certain distance, and air is filled at a gap between the reflection member 14 and the lower case 114. The material of the reflection member 14 may be polished stainless steel, which reflects the ultraviolet rays in the flow path, enhancing the ultraviolet irradiation amount to the fluid, and enhancing the sterilization effect.

As shown in fig. 1, in the present embodiment, the fluid treatment device 10 further includes an inner tube 15, the inner tube 15 is at least partially composed of a material that transmits ultraviolet rays and is at least partially disposed within the housing 11, and the inner tube 15 is configured to extend the fluid passage. The material of the inner tube 15 may be quartz glass. By providing the inner tube 15 in the fluid handling device, the fluid passes through the flow channel 103 in the reflective member 14, enters the flow channel 104 in the inner tube 15, and finally exits through the fluid outlet 112. This allows the flow path to be extended, resulting in a longer time for the fluid to flow through the device, and increases the amount of ultraviolet radiation of the fluid by the ultraviolet ray transmission of the inner tube 15, contributing to the sterilization and purification effects of the device.

As shown in FIG. 1, in the present embodiment, fluid treatment device 10 further includes a seal ring 16 configured to sealingly couple a top or bottom end of reflective member 14 within housing 11 to housing 11. Since the housing 11 of the fluid treatment apparatus 10 has a square cylindrical shape, the reflection member 14 has a cylindrical shape, and they are spaced apart from each other by a certain distance, it is necessary to hermetically couple the top and bottom ends of the reflection member 14 to the housing 11 using the sealing rings 16. The sealing ring 16 may be a profiled O-ring made of silicone. In use, the flow dividing member 13 is arranged to fit within the mounting hole of the sealing ring 16. Specifically, the seal ring 16 at the top inside the housing 11 is installed by first installing the shunt member 13 in the seal ring 16, then inserting the seal ring 16 into the upper housing 113, installing the top end of the reflection member 14 in the groove of the seal ring 16, and finally, screwing the seal ring 16 to the upper housing 113 using the screw 161. For the sealing ring 16 at the bottom in the housing 11, the quartz plate 121 is first embedded into the sealing ring 16, then the sealing ring 16 is installed at the bottom of the lower housing 114, the bottom end of the reflection part 14 is abutted against the groove of the sealing ring 16, and finally the sealing ring 16 is screwed and fixed at the bottom of the lower housing 114 by using screws. By fixing and further tightening the sealing ring 16, the sealing ring 16 is also configured to prevent fluid from entering the coupling of the reflective member 14 to the housing 11 and illuminating the assembly 12.

Fig. 4 and 5 show schematic views of a fluid processing device according to another embodiment of the present invention. The fluid treatment device 20 includes a housing 21, an illumination assembly 22, and a flow splitting member 23. Wherein the housing 21 defines a fluid inlet 211, a fluid outlet 212, and a fluid passage communicating the fluid inlet 211 with the fluid outlet 212. The housing 21 of this embodiment may be square-cylindrical. Specifically, the housing 21 is composed of an upper housing 213 and a lower housing 214. Both the fluid inlet 211 and the fluid outlet 212 are provided on the upper housing 213. The illumination assembly 22 of the fluid treatment device 20 is disposed within the housing 21 and is configured to emit ultraviolet light to illuminate the fluid flowing through the fluid channel. The flow dividing member 23 of the fluid processing device 20 is disposed in the fluid passage, the flow dividing member 23 includes a plurality of flow holes 231 therethrough, so that the fluid from the fluid inlet 211 flows out to the fluid outlet 212 through the flow holes 231 of the flow dividing member 23, wherein a side of the flow dividing member 23 facing the illumination assembly 22 is provided with a reflection portion 232, and the reflection portion 232 is configured to at least partially reflect the ultraviolet rays from the illumination assembly 22.

The fluid treatment device 20 further includes a reflective member 24, the reflective member 24 being disposed adjacent an inner wall of the housing 21, nested within the inner wall of the housing 21, and configured to at least partially reflect ultraviolet light within the flow channel. Furthermore, the fluid treatment device 20 comprises an inner tube 25, the inner tube 25 being at least partly composed of a material that is transmissive for ultraviolet light and being at least partly arranged within the housing 21, and said inner tube 25 being configured to prolong the fluid passage. In use of the device, fluid enters the flow channel 201 from the fluid inlet 211, then temporarily resides in the fluid channel 202 in the annular cavity, passes through the flow dividing member 23 into the fluid channel 203, and finally exits from the fluid outlet 212 through the flow channel 204 in the inner tube 25. During this time, the fluid passing through the flow channel is subjected to a large amount of irradiation of ultraviolet rays to kill bacteria therein.

In a clear distinction from the previous embodiment, the fluid treatment device 20 further comprises a transmissive part 26. Transmissive member 26 is disposed nested in an inner wall of reflective member 24 and is configured to at least partially transmit ultraviolet light. The transmission member 26 may be made of quartz glass, and may be cylindrical in shape. The reflective member 24 may be an aluminum foil, which is disposed to be closely attached to the outer wall of the transmissive member 26. By combining the reflection member 24 such as aluminum foil and the transmission member 26 such as quartz glass, the ultraviolet rays are continuously reflected and transmitted in the flow passage in the housing 21, and the reflectivity of the ultraviolet rays on the reflection member 24 is high, and the loss of the ultraviolet rays in the process of light propagation is small, so that the fluid passing through the flow passage is irradiated with sufficient ultraviolet rays, and a better sterilization and purification effect is achieved. Compared with the commonly used PTFE as a reflecting material on the market, the utility model provides a use polishing stainless steel or aluminium foil as the reflecting part can obviously reduce the manufacturing cost of the device.

Accordingly, the fluid treatment device 20 further comprises a sealing ring 27, the sealing ring 27 being configured to sealingly couple a top or bottom end of the transmissive part 26 within the housing 21 to the housing 21. The sealing ring 27 may be a profiled O-ring made of silicone. Specifically, as for the seal ring 27 at the top in the housing 21, the shunt member 23 is first installed in the seal ring 27, the seal ring 27 is then inserted into the upper housing 213, the top end of the transmission member 26 is installed in the groove of the seal ring 27, and finally, the seal ring 27 is screwed to the upper housing 213 using screws. At the bottom of the lower case 214, the bottom end of the transmissive part 26 is hermetically coupled to the case 21 using the packing 27. By stiffening and compressing the sealing ring 27, the sealing ring 27 is also configured to prevent fluid from entering the coupling of the transmissive member 26 to the housing 21 and illuminating the assembly 22.
