Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet sterilization, in particular to a flow-through water sterilization device. Background Art

[0002] Ultraviolet water sterilization is an efficient, non-chemical water treatment method. Ultraviolet sterilization mainly uses ultraviolet rays in the UV-C band, among which ultraviolet light with a wavelength of 253.7nm or 258nm is determined to be an effective band with a high sterilization rate. When water flows through the ultraviolet disinfection device, the ultraviolet light irradiates the water body, destroying the cell DNA and cell structure of bacteria, viruses and other microorganisms in the water, making them unable to regenerate, thereby achieving the disinfection and purification effect of the water body.

[0003] At present, there are two technical problems with ultraviolet water sterilization devices:

[0004] (1) When the flow rate of the water body changes greatly, the sterilization effect of the ultraviolet water sterilization device is less stable. Specifically, when the water flow rate suddenly increases, since the dose of ultraviolet light applied is fixed, the ultraviolet light is not enough to kill all bacteria, viruses and other microorganisms in the water;

[0005] (2) The ultraviolet rays have a short irradiation path in water and have a poor sterilization effect. Utility Model Content

[0006] In view of this, it is necessary to provide a flow water sterilization device to solve the technical problems that the existing ultraviolet water sterilization device has poor ultraviolet sterilization effect when the water flow velocity changes greatly and the ultraviolet irradiation path in the water body is short, resulting in poor sterilization effect.

[0007] In order to achieve the above object, the utility model provides a flow-through water sterilization device, comprising:

[0008] A water flow mechanism, comprising a transparent tube, a reflective film tube and two water distribution parts, wherein the reflective film tube is sleeved on the transparent tube, a light inlet hole is opened on the reflective film tube, and the two water distribution parts each comprise a water distribution cylinder and a water retaining cover, wherein the water distribution cylinder is fixed to one end of the transparent tube, the water retaining cover is fixed to the center of the water distribution cylinder, and a flow passage is formed between the outer side wall of the water retaining cover and the inner side wall of the water distribution cylinder; and,

[0009] The sterilization mechanism is used for emitting ultraviolet light into the transparent tube through the light inlet hole.

[0010] In some embodiments, the transparent tube is a quartz glass tube.

[0011] In some embodiments, the water flow mechanism further includes a middle shell, and the middle shell is fixedly mounted on the reflective membrane tube.

[0012] In some embodiments, an insertion ring groove for inserting the transparent tube is formed at one end of the water dividing cylinder, and mounting grooves are formed at both ends of the middle shell, and the water dividing cylinder is inserted into the mounting grooves.

[0013] In some embodiments, the water flow mechanism further includes a faucet cover plate, one end of which is detachably connected to the water diversion cylinder, and a joint is formed at the other end of the faucet cover plate, and the faucet cover plate is detachably connected to the middle shell.

[0014] In some embodiments, a plurality of supporting protrusions are formed on the inner wall of the water dividing cylinder, the water retaining cover is inserted into the water dividing cylinder, the outer wall of the water retaining cover abuts against each of the supporting protrusions, and a notch is formed at the end of the water retaining cover.

[0015] In some embodiments, one end of the faucet cover plate is interference fit with the water diversion cylinder, and the faucet cover plate abuts against the water retaining cover.

[0016] In some embodiments, a mounting screw hole is provided on the middle shell, a through hole is provided on the faucet cover plate, and the water flow mechanism further includes a fixing screw, which passes through the through hole and is threadedly connected with the mounting screw hole.

[0017] In some embodiments, a fixing opening is opened on the middle shell, and the sterilization mechanism includes a UVC sterilization lamp module and a cover plate, the UVC sterilization lamp module is fixed in the fixing opening, the lamp beads of the UVC sterilization lamp module are embedded in the light inlet, and the cover plate is fixedly covered on the fixing opening.

[0018] In some embodiments, the sterilization mechanism further includes a module driving unit and a connecting harness, wherein the module driving unit is connected to the UVC sterilization lamp module and is used to drive the UVC sterilization lamp module, and the connecting harness is electrically connected to the module driving unit.

[0019] Compared with the prior art, the beneficial effect of the technical solution proposed by the utility model is that when in use, the water to be sterilized is passed into the water dividing cylinder. After the water enters the water dividing cylinder, it is blocked by the water retaining cover, and the water flow turns back and enters the transparent tube from the flow channel between the outer wall of the water retaining cover and the inner wall of the water dividing cylinder. At this time, the sterilization mechanism emits ultraviolet light into the transparent tube through the light inlet hole. Under the action of the reflective film tube, the ultraviolet light is reflected back and forth in the transparent tube inside the reflective film tube for many times, thereby sterilizing the water in the transparent tube. The sterilized water enters another water dividing cylinder, and the water is blocked by the water retaining cover. The water flow turns back and is discharged from the flow channel between the outer wall of the water retaining cover and the inner wall of the water dividing cylinder. The utility model provides a water dividing cylinder and a water retaining cover at both ends of a transparent tube, and blocks the water flow through the water retaining cover, so that the water flow can only enter the transparent tube from the flow passage between the water retaining cover and the water dividing cylinder, thereby buffering the water flow and improving the flow velocity stability of the water flow in the transparent tube, thereby ensuring the sterilization effect of the flowing water; at the same time, by arranging a reflective film tube outside the transparent tube, the ultraviolet light can be reflected multiple times through the reflective film tube, thereby increasing the length of the path through which the ultraviolet light passes through the water body in the transparent tube, thereby improving the sterilization effect.
