Technical Field

[0001] The utility model belongs to the technical field of water purifiers, and in particular relates to a flowing water UVC sterilization module. Background Art

[0002] As society continues to progress and develop, people are paying more and more attention to their own health, and have put forward higher standards and requirements for diet and drinking water health, which are closely related to daily life. From the perspective of healthy drinking water, strict hygiene indicators are proposed for drinking water quality. Modern water purification devices that use high-tech technologies such as reverse osmosis are accelerating into thousands of households to improve people's drinking water health. In the process of using various filtering methods to purify water quality, there is a problem that is often easily overlooked, that is, the problem of secondary pollution of purified water. Because the purified water is affected by the storage environment or transportation pipeline during storage or transportation, the water quality changes, posing a potential threat to drinking water health.

[0003] UVC germicidal lamp, as a professional germicidal lamp, uses the UVC band and can effectively kill bacteria in a very short time. Therefore, this type of germicidal lamp is used in many fields.

[0004] However, the current sterilization effect of using UVC germicidal lamps in flowing water still has the problems of low sterilization efficiency and poor sterilization effect. Therefore, a solution is proposed to address the above problems. Utility Model Content

[0036] Reference Figure 1-9 As shown, this embodiment provides a flowing water UVC sterilization module, including:

[0037] A module body 1, a UVC lamp panel 5 is provided at the bottom of the module body 1, a light guide 2 is provided inside the module body 1, a quartz tube 3 is provided inside the light guide 2, and both ends of the quartz tube 3 are connected to pipe joints 8 through sealing members 9;

[0038] The side of the light guide 2 away from the UVC lamp board 5 is in contact with the side of the quartz tube 3 away from the UVC lamp board 5, and a gap chamber 4 exists between the side of the light guide 2 close to the UVC lamp board 5 and the side of the quartz tube 3 close to the UVC lamp board 5.

[0039] By arranging a light guide tube 2 inside the module body 1 and then cooperating with the UVC lamp board 5 at the bottom of the module body 1, the ultraviolet light generated by the UVC lamp board 5 is reflected by the light guide tube 2, so that the ultraviolet light can evenly irradiate the flowing water inside the quartz tube 3, and can also improve the sterilization efficiency of the UVC lamp board 5 on the flowing water in the quartz tube 3. Secondly, a gap chamber 4 is arranged on the side of the light guide tube 2 close to the UVC lamp board 5 and the side of the quartz tube 3 close to the UVC lamp board 5. This arrangement is beneficial to the heat dissipation of the UVC lamp board 5, and can also prevent condensation from occurring on the surface of the quartz tube 3, thereby affecting the light projection of the UVC lamp board 5, and thus affecting the sterilization effect of the water purification faucet.

[0040] Furthermore, a first lamp trough 7 adapted to the UVC lamp panel 5 is provided through the bottom of the module body 1 .

[0041] Furthermore, a second lamp trough 6 adapted to the UVC lamp panel 5 is provided through the bottom of the light guide 2 .

[0042] Furthermore, the height of the UVC lamps of the UVC lamp panel 5 is higher than the height of the first lamp trough 7 and lower than the sum of the heights of the first lamp trough 7 and the second lamp trough 6 .

[0043] By setting up the UVC lamp board 5 and cooperating with the light guide 2, the light irradiation of the UVC lamp board 5 is made more uniform, and the height of the UVC lamp is set to be higher than the height of the first lamp trough 7 and lower than the sum of the heights of the first lamp trough 7 and the second lamp trough 6. This setting can firstly avoid the module body 1 from blocking the light emitted by the UVC lamp, and secondly, it can also divide the light emitted by the UVC lamp into a directly irradiated part and a part refracted by the light guide 2. This setting can increase the range of light coverage emitted by the UVC lamp and make the light irradiation more uniform.

[0044] Furthermore, the UVC lamp board 5 is also electrically connected to a control circuit board, which is used to control the switch of the UVC lamp and stabilize the operating voltage of the UVC lamp.

[0045] Furthermore, the control circuit board needs to be treated to be moisture-proof.

[0046] Furthermore, the pipe joint 8 can be a quick-connect pipe joint, which includes a base and a connecting pipe. The base is detachably connected to the module body 1 by self-tapping screws. The connecting pipe is arranged at one end of the base away from the module body 1, and the connecting pipe and the base are integrally formed. The outer surface of the connecting pipe is provided with three groups of water-blocking convex rings arranged at intervals, and a water-blocking ring is also provided between two adjacent groups of water-blocking convex rings.

[0047] Furthermore, the pipe joint 8 may be a straight-insert pipe joint.

[0048] Furthermore, the pipe joint 8 can also be a quick-insert pipe joint, which includes a base and a tooth sleeve. The base is detachably connected to the module body 1 by self-tapping screws, and the tooth sleeve is arranged at the end of the base away from the module body 1, and the tooth sleeve and the base are integrally formed. A water-blocking ring is provided at the end of the tooth sleeve away from the base, and a claw is provided on the outer surface of the water-blocking ring. A cap is also provided at the end of the tooth sleeve away from the base, and the cap is adapted to be engaged with the claw.

[0049] By setting the pipe joint 8 to have various structures, the overall applicability of the flowing water UVC sterilization module is improved, and different types of products can be produced according to actual needs, thereby improving its applicability.

[0050] Furthermore, the light guide 2 is made of e-PTFE (expanded polytetrafluoroethylene), the quartz tube 3 is made of quartz glass transparent tube, the cross-sectional shape of the quartz tube 3 can be either circular or elliptical, and the cross-sectional shape of the light guide 2 is elliptical.

[0051] In this embodiment, the surface of the e-PTFE material has a plurality of micropores, thereby achieving multi-angle refraction of light, thereby improving the utilization rate of light.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
