The LED sterilization device 3 is arranged in the valve cavity 10, and the LED sterilization device 3 and the water outlet 104 are arranged at two ends of the valve cavity 10, respectively. The LED sterilization device 3 is arranged in the valve cavity 10 of the electromagnetic valve, and the LED sterilization device 3 is arranged at the end opposite to the water outlet 104, so that the sterilization range covers the entire valve cavity 10, and the covering effect is better.

[0053] By installing the LED sterilization device 3 in the valve body, on the one hand, the sterilization device is closest to the water outlet 104, which can avoid the problem that the traditional sterilization method installs the sterilizer at the water inlet 103 of the non-pressure electromagnetic valve, causing a large amount of stored water and exceeding the standard of total bacteria, and on the other hand, the electromagnetic valve can realize real-time sterilization, that is, the LED sterilization device 3 can be opened at irregular intervals when no one takes water, and the stored water in the valve body can be sterilized. At the same time, since the LED sterilization device 3 is installed in the valve body, it is close to the water outlet 104, and the risk of exceeding the standard of bacteria can be minimized. At the same time, the opening and closing of sterilization can be controlled in real time through the electric control logic, so as to realize real-time sterilization.

[0054] As shown in the Figures 2 to 4 The valve body includes an upper shell 2 and a lower shell 1 arranged in two parts, and the upper and lower shells 1 are fixed by bolts. The valve cavity 10 is located in the lower shell 1 and is closed by the upper shell 2. The upper shell 2 includes a valve core 21. The electromagnetic valve has a split shell, the upper shell 2 is used to install the valve core 21 structure, and can be detachably connected to the lower shell 1.

The annular outer cavity and the cylindrical inner cavity 102 form a zigzag circuit inside the valve cavity 10, and the water needs to be accumulated in the annular outer cavity 101 to a full state before entering the cylindrical inner cavity 102 from the top communication port 110, and the bottom of the cylindrical inner cavity 102 is the water outlet 104, so that the water flow entering the cylindrical inner cavity 102 will directly flow out without accumulation. It is ensured that only the annular outer cavity 101 has stored water and all water outlets will flow through the annular outer cavity 101.

[0057] The annular wall 11 separates the valve cavity 10 into two parts, the inner cylindrical inner cavity 102 is used for water outlet, and the outer annular outer cavity is used for water storage. When water is used, the electromagnetic valve is opened, and the water flow enters the inner cylindrical inner cavity 102 from the outer annular outer cavity and flows out from the water outlet 104, and when water is not used, the water in the inner cylindrical inner cavity 102 flows out without storage, and a certain amount of residual water is retained in the outer annular inner cavity. These residual water is sterilized by the LED sterilization device 3 arranged in the annular outer cavity to prevent bacterial growth.

The reflector 4 is made of stainless steel, and the surface is a mirror surface, which can efficiently reflect ultraviolet light and increase the sterilization effect. The bottom of the valve cavity 10 has a plurality of blind holes for fixing the reflector 4. The reflector 4 is fixed by self-tapping screws 41.

[0060] As shown in Figure 2 , 4As shown, the electromagnetic valve includes a valve core 21 capable of opening and closing the communication port 110. The electromagnetic valve is controlled by the valve core 21. Specifically, the electromagnetic valve further includes a coil, the valve core 21 is a kind of armature, the coil inside is copper or aluminum, after energization, the magnetic force is generated to the top of the armature rail pressing plate. A spring is also arranged inside, the spring is made of stainless steel material, and the main function is to provide a reverse force to the armature, so that it can better boost the sealing ring to the sealing port of the valve body, to ensure no water leakage. The armature is made of metal material and can be guided by magnetic force. Meanwhile, the top of the armature has a groove, which can position the spring in the groove, so that it cannot displace in other directions.

[0061] As shown in Figures 2 to 4 , an annular sealing ring 32 is further arranged between the upper shell 2 and the lower shell 1, a circular hole is formed in the middle of the annular sealing ring 32, the valve core 21 passes through the circular hole, and an annular light-transmitting sheet 31 is further arranged in the circular hole. The outer end of the annular light-transmitting sheet 31 is sealingly connected with the circular hole, and the inner end of the annular light-transmitting sheet 31 is sealingly connected with the valve core 21. By arranging the sealing ring and the annular light-transmitting sheet 31 on the sealing ring, this structure can conveniently realize sealing.

[0062] The bottom of the annular sealing ring 32 is clamped in the sealing groove 12 on the upper part of the lower shell 1, the wall surface of the circular hole is concave to form a fixing groove, and the annular light-transmitting sheet 31 is clamped in the fixing groove. It is fixed firmly and has good sealing effect.

[0063] The electric connection line 33 of the LED sterilization device 3 is transmitted from the upper shell 2 and can be electrically connected with the outside. The electric connection line 33 mainly provides power supply for the LED sterilization device 3, and the control system can control the opening and closing of the LED sterilization device. The electric connection line 33 is arranged on the upper shell 2 and is transmitted from the top. It can utilize the sealing effect of the annular sealing ring 32 and is isolated from the valve cavity 10 to avoid being damaged by the water flow in the valve cavity 10.

[0064] As shown in Figure 2 , 3 , the diameter of the cylindrical inner cavity 102 gradually decreases in the direction of the water outlet 104, and the water outlet 104 is provided with a flow guide rib 105. The water outlet 104 has an upper and lower structure, the diameter of the upper part is slightly larger than that of the lower part, so that the water flow is concentrated when the water is discharged. Meanwhile, the water outlet 104 has a plurality of flow guide ribs 105, which can effectively correct the water type and ensure that the water is not skewed and sprayed.

[0065] In actual operation, the electric connection line 33 of the electromagnetic valve and the connection line of the LED sterilization device 3 are independently separated, which can ensure that the LED sterilization device is independently opened and closed, that is, even if the electromagnetic valve is not opened, the sterilization device can also be opened.

[0066] When the water flows into the valve body, that is, the plug terminal is electrified, the coil attracts the armature to the top, at this time the valve body is opened, and the LED sterilization device 3 is also opened synchronously, so that real-time sterilization is realized.

[0067] When the valve body is opened after being water for a period of time, the system detects that the preset time is reached, and the LED sterilization device 3 is opened alone for a preset time, so that the stored water in the valve body can be sterilized.
