The end-inlet water sterilization faucet shown in fig. 1-4 comprises a valve seat 1, an outer tube 2, a sterilization module, a water outlet 3, two water inlet tubes 4 and two water outlet switches 5, wherein the two water outlet switches 5 are respectively arranged on two sides of the valve seat 1, the two water inlet tubes 4 are introduced from the lower part of the valve seat 1, the on-off of water flow is respectively controlled by the water outlet switches 5 on two sides, the sterilization module is positioned in the outer tube 2 and comprises a cold cathode ultraviolet sterilization lamp 6, a quartz sleeve 8 and a lamp holder 7, the cold cathode ultraviolet sterilization lamp 6 and the lamp holder 7 are positioned in the quartz sleeve 8, the lower end of the quartz sleeve 8 is sleeved on the valve seat 1, the lower end of the cold cathode ultraviolet sterilization lamp 6 is installed on the lamp holder 7, and a sterilization space is formed between the cold cathode ultraviolet.

As shown in fig. 4 and 5, the lamp holder 7 includes a base 73, the diameter of the base is the same as the inner diameter of the quartz sleeve, two water inlets 71 are in a grid shape and are respectively opened at two sides of the base 73, a mounting post 74 is provided on the upper surface of the base 73, a mounting hole for mounting the cold cathode uv germicidal lamp 6 is provided in the mounting post 74, and the mounting hole is attached to the lower end of the cold cathode uv germicidal lamp 6. Two circles of sealing grooves are further formed in the mounting hole, sealing rings are arranged in the sealing grooves, and the sealing rings in the mounting hole are in interference fit with the lower end of the cold cathode ultraviolet germicidal lamp 6, so that the germicidal lamp can be guaranteed not to have water to enter and contact with the electrodes after being mounted on the lamp holder.

A waterproof tube 72 for placing the electrode of the cold cathode ultraviolet germicidal lamp is arranged downwards at the bottom of the lamp holder 7, and when the germicidal lamp is installed in the lamp holder, the electrode is inserted into the waterproof tube from top to bottom. As shown in fig. 6, a waterproof hole 13 for placing a waterproof pipe 72 is formed downward at the top of the valve seat 1, and a sealing ring is also arranged between the waterproof pipe and the waterproof hole 13. The bottom of the valve seat 1 is also provided with a wire arranging hole 11 communicated with a waterproof hole 13, and a power supply input wire is accessed from the outside and is connected with an electrode in the waterproof pipe inserted into the waterproof hole after passing through the wire arranging hole. The waterproof pipe 72 is arranged on one side of the bottom of the base 73, the positioning column 75 is arranged on the other side of the bottom of the base 73, and the base 73, the waterproof pipe 72, the mounting column 74 and the positioning column 75 are of an integrated structure and can be formed by machining through a stainless steel block. Still offer the locating hole 12 that is used for placing reference column 75 downwards at disk seat 1 top, the height that highly is greater than waterproof hole 13 of waterproof pipe 72, the height that highly is greater than locating hole 12 of reference column 75, and the height that both are high is the same, consequently after reference column and waterproof pipe insert, contactless and can keep balance between the bottom lower surface of lamp stand and the top upper surface of disk seat, because quartz sleeve's lower pot head is established on the disk seat, consequently forms intake antrum 9 between base and the disk seat top that is lived by quartz sleeve parcel.

Be equipped with two inlet openings 11 in valve body 1, the lower extreme of inlet opening 11 communicates with an inlet tube 4 respectively, the upper end and the intake antrum intercommunication of inlet opening 11, the break-make of rivers is controlled by the play water switch 5 of both sides respectively in two inlet openings 11, its concrete control mode is the same with the mode that two water switch control two routes water pipes intake on the market, the tap of two switches of cold and hot on the market at present mode of intaking homoenergetic uses this tap, two routes inlet tube can be designed into high low level and intake, set up at different heights promptly, when being convenient for install. The inlet tube 4 can communicate with the intake antrum after the switch that goes out opens, is equipped with water inlet 71 in the both sides of lamp stand 7, and the intake antrum passes through water inlet 71 and the space intercommunication that disinfects, delivery port 3 and the top intercommunication in space that disinfects, after one or two switches that go out opened, rivers let in the intake antrum from the inlet tube, get into the space that disinfects through the water inlet again and disinfect, and the rivers after disinfecting flow through the delivery port. Because the water inlet of base both sides is the grid structure of slope, and the angle of slope is the same, consequently when rivers gush out from the water inlet, can flow along the incline direction, the intaking of both sides after meeting, not only can form the vortex, can slow down the velocity of flow in addition, strengthens ultraviolet sterilization.

According to the invention, through the matching of the valve body and the lamp holder, a water inlet cavity is formed between the valve body and the lamp holder, and two paths of inlet water can enter the water inlet cavity through the valve body. The connection part of the lamp holder and the germicidal lamp is arranged above the water inlet cavity, and water flow upwards emerges from the water inlets at two sides, so that direct impact of the water flow on the water inlet cavity is avoided; the lamp holder base bearing direct impact of water flow is provided with the bactericidal lamp, and the bactericidal lamp is pressed by the water outlet pipe with the top fixed on the outer pipe and the quartz pipe, so the lamp holder base bearing direct impact of water flow is not easy to loosen after bearing impact. The electrode of bactericidal lamp is located the waterproof pipe, and the waterproof pipe is then inserted in the waterproof hole of valve body, because the waterproof pipe is located the below of intake antrum, consequently also can not receive the direct impact of rivers. Namely, two positions that need to set up the sealing washer, the impact of rivers can both be avoided through the cooperation of valve body and lamp stand, therefore the sealing washer non-deformable, difficult leaking, the security is higher, and life is also longer.

in light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
