The sterilisation apparatus may be applied to any suitable water purification machine. The sterilizing device may be arranged at any suitable position in the water purifier, for example, upstream of the filter element of the water purifier, downstream of the filter element, etc., and preferably, the sterilizing device is arranged on the water outlet pipeline of the water purifier for sterilizing the purified water filtered by the filter element. Of course, the sterilization apparatus can also be applied to other devices, such as a faucet, if necessary.

As shown in fig. 1-5, the sterilization device may include a housing 100, a light transmitting tube 200, and an ultraviolet LED lamp 300.

The housing 100 generally has an elongated configuration. The exemplary housing 100 is generally cylindrical as shown. Of course, the housing 100 may have various prism shapes. The housing 100 may include a first end 131 and a second end 132 disposed opposite one another. The water inlet 111 and the water outlet 112 are provided on the end of the housing 100. In the embodiment shown in the figures, the water inlet 111 and the water outlet 112 are provided on the same end of the housing 100. In other embodiments not shown, the water inlet 111 and the water outlet 112 may be disposed on the first end 131 and the second end 132, respectively. The side wall 140 of the housing 100 is connected between the first end 131 and the second end 132.

The light transmitting tube 200 may be disposed within the housing 100. The two ends of the light-transmitting pipeline 200 can be respectively communicated with the water inlet 111 and the water outlet 112 on the casing 100. Alternatively, both ends of the light transmitting pipe 200 may be connected to the water inlet 111 and the water outlet 112, respectively, and the external pipe communicates with the light transmitting pipe 200 by connecting the water inlet 111 and the water outlet 112. Alternatively, both ends of the light transmitting pipe 200 may communicate with an external pipe through the water inlet 111 and the water outlet 112, respectively. The light-transmissive tube 200 may be made of any suitable light-transmissive material, such as light-transmissive glass, light-transmissive plastic tube, and the like.

The ultraviolet LED lamp 300 is disposed at the sidewall 140 of the housing 100 to irradiate the light transmitting tube 200 from the side, thereby sterilizing the water flowing through the light transmitting tube 200. The number of ultraviolet LED lamps 300 may be arbitrary. Illustratively, the housing 100 may be provided with a through hole 120. The shape of the through-hole 120 is not limited. The ultraviolet LED lamp 300 may be disposed outside the housing 100 with the ultraviolet LED lamp 300 aligned with the through-hole 120.

Illustratively, the ultraviolet LED lamp 300 may also be disposed inside the housing 100, for example, fixed to the sidewall 140 of the housing 100.

The ultraviolet LED lamp 300 may employ various types of ultraviolet LED lamps known in the art or may come out in the future as long as it can sterilize water. The ultraviolet disinfection technology has incomparable sterilization efficiency with other technologies, and the sterilization efficiency can reach 99-99.9%. Ultraviolet rays mainly act on DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) of microorganisms such as bacteria and the like to destroy the molecular structure of the DNA or RNA, so that the DNA or RNA loses the functions of reproduction and self-replication, thereby achieving the aim of sterilization. The ultraviolet sterilization has the advantages of no color, no smell and no chemical substance left. Ultraviolet LED lamps have many advantages over conventional ultraviolet lamps, such as longer service life; the heat productivity of the ultraviolet LED lamp is smaller, so that the serious heating of the sterilizing device caused by long-time work can be prevented; the ultraviolet LED lamp can be instantly lightened, and 100% power ultraviolet output can be achieved without preheating; the ultraviolet LED lamp does not contain mercury and generate ozone, so that the ultraviolet LED lamp is more environment-friendly and reliable; the ultraviolet LED lamp is more energy-saving; the ultraviolet LED lamp is smaller and more compact, and the like. The specific structure and lighting principles for ultraviolet LED lamps are well known in the art and therefore will not be described in further detail herein.

Water to be sterilized may enter the light transmitting pipe 200 through the water inlet 111. After the water in the transparent pipeline 200 is sterilized by the ultraviolet rays emitted from the ultraviolet LED lamp 300, the water may flow out through the water outlet 112, thereby completing the sterilization.

Since the ultraviolet LED lamp 300 generally has a large emitting angle, the ultraviolet LED lamp 300 is disposed on the side wall 140 of the housing 100, and there is no object to block the ultraviolet rays, so that the irradiation area of the ultraviolet rays to the light transmission pipeline 200 is larger. Through rationally selecting the emission angle of ultraviolet LED lamp 300, the length of shell 100, the position of ultraviolet LED lamp 300 on lateral wall 140 and the distance of ultraviolet LED lamp 300 to printing opacity pipeline 200, can make printing opacity pipeline 200 all shine by ultraviolet LED lamp 300, consequently under the prerequisite that does not improve the power of ultraviolet LED lamp 300, the bactericidal efficiency is higher, the bactericidal effect is better, the quality of water through sterilizing equipment is higher, user's health obtains guaranteeing.

Preferably, as shown in fig. 1 to 4, the ultraviolet LED lamp 300 may be disposed at the middle of the side wall 140 of the housing 100. Thus, the area of the transparent pipeline 200 that can be irradiated under the condition that the emission angle of the ultraviolet rays is fixed is larger, and the sterilization effect of the sterilization device is better.

Preferably, as shown in fig. 1-5, the water inlet 111 and the water outlet 112 may both be disposed at the first end 131. In this way, the light transmitting pipe 200 has at least one bend, thereby increasing the length of the light transmitting pipe 200, extending the time for water to flow through the light transmitting pipe 200, i.e., the time for which the ultraviolet LED lamp 300 is irradiated, and thus improving the sterilization effect. Illustratively, as shown in fig. 5, the light transmitting pipe 200 may have a U-shape. In other embodiments not shown, the light pipe 200 may also be spiral or W-shaped. The light transmission pipeline 200 in the above shape is convenient to process.

Alternatively, as shown in fig. 1-5, the housing 100 may include a bottle body 151 having a mouth and a bottle cap 152. Bottle cap 152 may close the mouth of the bottle, with bottle cap 152 defining first end 131. The bottle cap 152 may be coupled to the bottle body 151 in various manners. In the illustrated embodiment, the bottle cap 152 may be threadedly coupled to the bottle body 151. In other embodiments not shown, the bottle cap 152 may be connected to the bottle body 151 by snapping, bonding, welding, or the like. The water inlet 111 and the water outlet 112 may be provided on the bottle cap 152. During the assembly process, the light-transmitting pipeline 200 may be fixed to the bottle cap 152 and then mounted to the bottle body 151. Therefore, the structure has the advantages of convenience in processing and manufacturing and the like.

Further, as shown in fig. 2-5, the light transmission line 200 and the second end 132 may be spaced apart. The sterilization apparatus may further include an elastic member 400. The elastic member 400 may be disposed between the second end 132 and the light transmitting tube 200. Preferably, the elastic member 400 may include a spring. When the water pressure of the water passing through the light transmitting pipe 200 rises, it may impact the light transmitting pipe 200. Therefore, by spacing the light transmitting tube 200 from the second end 132, the light transmitting tube 200 and the housing 100 can be prevented from colliding, causing damage to the light transmitting tube 200 and the housing 100. The elastic member 400 can be used to support the light transmission pipeline 200, so as to prevent the light transmission pipeline 200 from colliding with the housing 100 and being damaged during the use process, thereby prolonging the service life of the sterilization device. Furthermore, during the assembly process, the elastic member 400 may be placed in the housing 100 before the light-transmitting tube 200 and the bottle cap 152 are fixed together. In this way, the elastic member 400 may provide a buffer protection function for the light transmitting pipe 200, especially in the case where the light transmitting pipe 200 is made of glass. Therefore, damage caused by direct impact on the housing 100 due to the fact that the light transmitting pipeline 200 falls off from the bottle cap 152 or excessive force is applied in the assembling process can be avoided.

Preferably, the housing 100 may be provided with a through hole 120. Ultraviolet rays emitted from the ultraviolet LED lamp 300 are irradiated to the light transmitting pipe 200 through the through-hole 120 in the sidewall 140 of the housing 100. Thus, once the ultraviolet LED lamp 300 is damaged, the ultraviolet LED lamp 300 can be conveniently replaced and repaired.

Further, as shown in fig. 1 to 4, the sterilization apparatus may further include a lamp cover 500. The lamp cover 500 may be connected to the housing 100. The ultraviolet LED lamp 300 may be accommodated in the lamp cover 500. By arranging the lamp cover 500, the ultraviolet LED lamp 300 can be protected, and the ultraviolet LED lamp 300 can be prevented from being damaged by external force. Optionally, the lamp cover 500 may be provided with a lamp cover hole 510. The ultraviolet LED lamp 300 may include a cable, which may be electrically connected with the outside through the lamp cover hole 510. The ultraviolet LED lamp 300 may be powered and controlled by a cable. Alternatively, an electric storage means such as a battery may be provided in the sterilization device, and the ultraviolet LED lamp 300 may be electrically connected to the outside by wireless communication.

Further, as shown in fig. 1-4, the lamp cover 500 is detachably coupled to the housing 100. In the embodiment shown in the figures, the lamp housing 500 may be screwed to the housing 100. In other embodiments not shown, the lamp enclosure 500 may be snap-fit to the housing 100. With this arrangement, when the ultraviolet LED lamp 300 needs maintenance replacement, it is easy to detach and install.

Preferably, as shown in fig. 3 and 5, the inner surface 160 of the housing 100 may be provided with a light reflective layer (not shown). The manner in which the light-reflective layer is disposed on the interior surface 160 of the housing 100 is not limited. Alternatively, a light reflecting layer may be plated or coated on the inner surface 160 of the housing 100, for example, the light reflecting layer may be silver plated or coated. Optionally, a reflective layer may also be affixed to the inner surface 160 of the housing 100, for example, the reflective layer may be a reflective sticker. By providing the reflective layer, when the ultraviolet rays irradiate onto the inner surface 160 of the housing 100, the ultraviolet rays can be reflected, so that the irradiation area can be increased, the irradiation dead angle can be prevented, and the utilization rate of the ultraviolet rays can be improved, so that the sterilization effect of the sterilization apparatus is better.
