Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As shown in Figures 1-5, this utility model provides a technical solution: a sterilization device with a trigger element, including a trigger assembly 100 with a water inlet 101 and a sterilization element 200 with a water outlet 201. The trigger assembly 100 is used to control the on / off state of the sterilization element 200. A trigger element end cap 104 with an inner cavity is also provided along the water outlet direction of the water inlet 101. A water tank 105 is also provided at the lower end of the trigger element end cap 104. The water tank 105 also has an elastic tank bottom 105-1. A movable element 106 is also attached to the lower end face of the tank bottom 105-1. A spring 108 is also embedded in the inner side of the movable element 106. In addition, the trigger assembly 100 also includes a water passage element 110, wherein the movable element 106 and the spring 108 are both limited in the water passage element 110. The movable element 106 can move along the water passage element. The water supply component 110 moves up and down to help the bottom of the chamber 105-1 reset. A conductor 102 is also provided between the bottom of the chamber 105-1 and the movable part 106. The water supply component 110 also has a limit hole 110-2 for the conductor 102 to move up and down. The trigger component 100 also includes a control board 107. Two contact switches 107-1 are provided on the control board 107 to cooperate with the conductor 102. The control board 107 with contact switches 107-1, the conductor 102, the movable part 106 and the spring 108 form an elastic switch. The elastic switch can be used to control the opening and closing of the sterilization component 200. When there is water, the sterilization component 200 is opened. When there is no water, the spring 108 in the elastic switch causes the movable part 106 to move up and reset the conductor 102, thereby closing the sterilization component 200.

[0028] Furthermore, as shown in Figures 1 and 3, the water inlet 101 with a water inlet and the trigger end cap 104 form a water inlet channel, so that the water flow can eventually enter the water tank 105.

[0029] Furthermore, as shown in Figure 3, the edge of the water tank 105 is squeezed by the trigger end cap 104 and the water passage 110 near the two end faces to seal it and prevent water from flowing out from the gap between the water tank 105 and the trigger end cap 104 and the water passage 110, thus preventing pressure leakage.

[0030] In addition, the multiple sets of water outlet holes a104-1 opened circumferentially on the inner side of the trigger end cap 104, the water passage component 110, the transition component 109 and the bearing component 203 constitute a water passage channel.

[0031] In use, water flows through the inlet of the inlet component 101 and the water passage of the trigger end cap 104 into the water tank 105, where it is stored in the tank bottom 105-1. Under water pressure, the tank bottom 105-1 presses down on the conductor 102, causing it to contact the contact switch 107-1. This causes the control board 107 to open the sterilization component 200. When there is no water pressure, the spring 108 moves the movable component 106 upward to reset, separating the conductor 102 from the contact switch 107-1, thus closing the sterilization component 200. The control board... 107 and sterilization component 200 are electrically connected. In addition, when no water flows through, the water flow at the bottom 105-1 of the water tank 105 is higher than the water flow at the outlet a104-1 and eventually flows into the water pipe 300 along the water channel 110-1, and then is discharged from the outlet component 201 through the outlet hole b203-1 opened by the bearing component 203. The contact switch 107-1 has a positive and negative pole structure, and the conductor 102 is an electrically conductive metal component, such as copper. Touch control is common on the control board 107 and is existing technology, so it will not be described in detail in the text.

[0032] Furthermore, as shown in Figures 1-3, sealing rings 103 are provided between the water inlet component 101 and the trigger end cap 104, between the transition component 109 and the water passage component 110, between the transition component 109 and the water passage pipe 300, between the bearing component 203 and the water passage pipe 300 and the water outlet component 201. A water outlet pipe 201-1 is also sealed inside the water outlet component 201, and a sealing ring 103 is also provided between the water outlet pipe 201-1 and the water outlet component 201.

[0033] Furthermore, the water tank 105 and the tank bottom 105-1 are both made of the same material, which is a one-piece molded elastic material, preferably silicone or rubber.

[0034] Furthermore, as shown in Figures 2-3, an upper cover 109-2 is extended along the upper part of the transition member 109, and a lower cover 203-2 is extended along the lower part of the support member 203. The upper cover 109-2 is used for the overlap of the control plate 107.

[0035] The sterilization component 200 includes multiple sets of sterilization lamp plates 204 arranged circumferentially inside the housing 400. A water pipe 300 is arranged in the middle of the multiple sets of sterilization lamp plates 204. The irradiation direction of the sterilization lamp plates 204 is towards the water pipe 300. The water pipe 300 is made of quartz glass so that the light emitted by the sterilization lamp plates 204 can pass through to sterilize the water flow in the water pipe 300.

[0036] Furthermore, as shown in Figures 1-3, the inner side of the trigger end cap 104 is also provided with multiple sets of water outlet holes a104-1 in a circumferential manner. A water channel 110-1 is provided in cooperation with the water outlet holes a104-1. The water channel 110-1 is provided through the inner side of the water channel 110. Water flows out through the water outlet holes a104-1 to the water channel 110-1. A transition piece 109 is also provided between the water pipe 300 and the connecting piece 420 to transition and receive the water flow in the water channel 110-1. The inner side of the transition piece 109 is also provided with multiple sets of water outlet holes b109-1 in a circumferential manner. Water flows into the water pipe 300 through the water outlet holes b109-1.

[0037] Furthermore, the germicidal lamp plate 204 is made of a single-sided aluminum substrate or copper substrate, and the lamp beads arranged on the germicidal lamp plate 204 should be composed of high-power UVC LEDs, so as to complete the sterilization treatment of the water flow in a few seconds.

[0038] Furthermore, as shown in Figure 1, the back heating area of ​​the germicidal lamp plate 204 is in contact with the inner wall of the housing 400. The housing 400 can be made of a material with good thermal conductivity and heat dissipation properties, such as aluminum. When the germicidal lamp plate 204 heats up, the main heat is concentrated on the back of the germicidal lamp plate 204, but it is transferred to the aluminum housing 400 and then dissipated.

[0039] Furthermore, as shown in Figures 2 and 3, the upper cover 109-2 and the lower cover 203-2 are used to receive the germicidal lamp plate 204 and the two ends of the water pipe 300.

[0040] Furthermore, the aforementioned water outlet a104-1, water channel 110-1, water outlet b109-1, and water inlet 203-1 form a water channel to introduce water from the trigger component 100 into the sterilization component 200 for disinfection, and discharge the water from the sterilization device after disinfection.

[0041] Furthermore, the sealing ring 103 can also be replaced by sealant or other structures with sealing function.

[0042] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
