Description

Technical Field

[0001] This utility model relates to the field of sterilization device technology, specifically to a sterilization device with an active trigger. Background Technology

[0002] Existing fluid sterilization modules employ high-power UVC LEDs to rapidly sterilize flowing fluids. Heat dissipation relies primarily on aluminum alloy or other heat-dissipating metal casings to dissipate the heat generated by the UV LEDs. This single heat dissipation method is slow, and excessive heat still accumulates within the sterilization module, resulting in a short product lifespan. Furthermore, the fluid sterilization module requires user intervention to turn off; once it starts operating, it remains in this state regardless of whether fluid is flowing through it, easily leading to dry burning. To address these issues, the inventor provides a sterilization device with an active trigger. Utility Model Content

[0003] The purpose of this invention is to provide a sterilization device with an active trigger to solve the above-mentioned technical problems.

[0004] This utility model provides the following technical solution:

[0005] A sterilization device with an active trigger, characterized in that it comprises:

[0006] A triggering component with a water inlet and a sterilization component with a water outlet;

[0007] The triggering component includes a water tank, the bottom of which is also elastically set with a tank bottom, and an elastic switch is also fitted to the bottom of the tank bottom. The triggering component also includes a sealed water passage, which includes a first branch channel and a second branch channel that are interconnected.

[0008] Water flows along the inlet to the first diversion channel and into the water tank. The bottom of the tank is subjected to water pressure downwards, causing the elastic switch to open. When there is no water pressure at the bottom of the tank, the elastic switch is elastically reset and disconnected. The elastic switch is used to control the sterilization element to open / close.

[0009] The sterilization device further includes a sterilization zone, and the sterilization component includes a sterilization lamp plate. The sterilization lamp plate includes a back side of the lamp plate, and a glass plate is also sealed along the irradiation direction of the sterilization lamp plate.

[0010] A portion of the water flowing along the second diversion channel flows to the back of the germicidal lamp plate for heat dissipation, while the remaining water flows along the second diversion channel to the sterilization zone, where it is sterilized by the germicidal lamp plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, an elastic chamber bottom is provided, and an elastic switch is provided at the bottom of the chamber bottom. When fluid passes through, the elastic switch is pressed downward by the water pressure at the bottom of the chamber, causing the sterilization element to open. When no fluid passes through, the elastic switch returns to its elastic state, causing the sterilization element to close. This can prevent dry burning. In addition, a water passage is provided to transport water to the heat dissipation cavity to dissipate heat from the back of the sterilization lamp plate, improving the reliance on a single natural heat dissipation method and ensuring the service life of the sterilization device.

[0024] 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.

[0025] Generally speaking, sterilization devices for sterilizing fluids typically use ultraviolet light with strong penetrating power to kill harmful substances in the fluid (such as water or air).

[0026] For example, a sterilization device includes at least a sterilization lamp and a fluid passage section. The sterilization lamp is controlled by a switch. Most existing sterilization devices are manually controlled, while a few can be turned on when fluid passes through and turned off when no fluid passes through. However, the structure of such self-sensing switches is relatively complex.

[0027] In response, this disclosure provides a sterilization device with an active trigger, which can be turned on when fluid passes through and turned off when no fluid passes through in a purely mechanical manner, while also providing heat dissipation for the sterilization device. The fluid is cold water flow as an example.

[0028] like Figure 1 As shown, this embodiment of the present disclosure provides a sterilization device with an active trigger, including a triggering component 100 having a water inlet 101 and a sterilization component 200 having a water outlet 207, wherein the water inlet 101 has a water inlet, the triggering component 100 is used to control the opening and closing of the sterilization component 200, the sterilization device also includes a water passage for water flow and a sterilization zone 330 for accommodating water flow.

[0029] In this embodiment, water enters from the water inlet 101 of the trigger component 100 and flows to the sterilization zone 330 through the water passage. After sterilization is completed, water flows from the sterilization zone 330 to the water outlet 207 and is discharged from the outside of the sterilization device.

[0030] like Figure 2-6 The diagram shown illustrates a cross-sectional view of the triggering component 100 and the sterilization component 200 in this embodiment. (Refer to...) Figure 2 The trigger assembly 100 also includes a first end cap 102 fixedly fitted with the water inlet 101. A trigger end cap 104 with an inner cavity is also provided along the water outlet direction of the water inlet 101. The trigger end cap 104 has a water outlet, and a water tank 105 is also provided at the lower end of the trigger end cap 104. The water tank 105 also has an elastic tank bottom 1051. An elastic switch is also attached to the lower end face of the tank bottom 1051. The elastic switch is used to control the opening and closing of the sterilization component 200. When water flows into the tank bottom 1051, it is pressed down by the water pressure, and the sterilization component 200 is opened. When there is no water pressure, the elastic switch is elastically reset, and the sterilization component 200 is closed. This corresponds to the sterilization component 200 being opened to sterilize the water when there is water flow, and being closed when there is no water flow to avoid the problem of dry burning.

[0031] Furthermore, the resilient switch includes a movable member 106 disposed at the bottom of the compartment 1051, and a spring 1061 is also embedded in the inner side of the movable member 106. A conductive member 109 is attached to the top end face of the movable member 106. In addition, the resilient switch also includes a control board 108 for control. A two-contact switch 1081 (representing the cathode and anode) is also disposed on the top end face of the control board 108. When the conductive member 109 contacts the two-contact switch 1081, the circuit is closed. At this time, the control board 108 controls the sterilization member 200 to open, and conversely, the sterilization member 200 is closed.

[0032] Furthermore, the trigger assembly 100 also includes a water passage component 107, a movable component 106 and a spring 1061, all of which are limited in the water passage component 107. The movable component 106 can move up and down along the water passage component 107 to help the bottom of the tank 1051 reset. In addition, the water passage component 107 is also provided with a limiting hole 1072 for the conductor 109 to move up and down.

[0033] Furthermore, such as Figure 2-4As shown, the sterilization device also includes a housing 300, the upper inner wall of which is integrally formed with an overlapping member 340. The overlapping member 340 is also symmetrically provided with support grooves 320. The sterilization component 200 includes a support member 204 embedded in the support groove 320, and a water outlet cylinder 206 provided along the bottom of the support member 204. The water passage includes a first diversion channel and a second diversion channel. The first diversion channel includes a trigger end cap 104, and the second diversion channel includes a section formed on the trigger end cap 104. The water outlet a1041 on the inner axial direction, the water passage 107 and the water passage groove 1071 vertically opened thereon, wherein the support member 204 is also provided with a flow groove 205 for accommodating water flow by being recessed downward along its edge, and the water passage part 310 composed of the outer shell 300 and the support member 204, and the water outlet c2061 opened on the inner side of the water outlet cylinder 206, and a sealing ring 103 is also provided between the overlapping member 340 and the water passage 107 and between the inner wall of the outer shell 300 and the water outlet cylinder 206.

[0034] Furthermore, such as Figure 2 As shown, sealing rings 103 are provided between the water inlet 101 and the first end cap 102, and between the first end cap 102 and the trigger end cap 104. Furthermore, as... Figure 2 As shown, the edge of the water tank 105 is squeezed by the near end faces of the trigger end cap 104 and the water passage 107 to seal it and prevent water from flowing out from the gap between the water tank 105, the trigger end cap 104 and the water passage 107, causing a pressure relief problem.

[0035] Furthermore, the water tank 105 and the tank bottom 1051 are both made of the same material, which is a one-piece molded elastic material, preferably silicone or rubber.

[0036] Furthermore, such as Figure 2 and Figure 8 As shown, the sterilization component 200 also includes a sterilization lamp plate 201 fixedly sealed on the support member 204. A glass plate 203 is arranged in the light direction of the sterilization lamp plate 201, and a sealing gasket 209 is arranged in cooperation with the glass plate 203. The edge of the glass plate 203 is sealed in the sealing gasket 209, and the sealing gasket 209 is sealed in the support member 204. The sterilization lamp plate 201 is sealed between the sealing gasket 209 and the support member 204. A sealing ring 103 is also provided between the water outlet cylinder 206 and the outer shell 300.

[0037] Furthermore, such as Figure 1 As shown, a second end cap 208 is provided in conjunction with the water outlet component 207, wherein the upper and lower ends of the outer shell 300 respectively support the first end cap 102 and the second end cap 208.

[0038] Furthermore, the LEDs on the germicidal lamp panel 201 are composed of high-power UVC LEDs.

[0039] Furthermore, glass plate 203 is quartz glass or other glass types that allow ultraviolet light to pass through.

[0040] like Figure 9 The direction of water flow, 'a', is shown in this embodiment. (Refer to...) Figure 7 Water flows through the inlet 101 into the trigger end cap 104. Part of the water flows into the bottom 1051 of the water tank 105. The water pressure created by the sealing structure (i.e., the sealing ring 103 and the pressure exerted by the trigger end cap 104 and the water passage 107 on the edge of the water tank 105) causes the bottom 1051 to press the movable part 106 downwards. The conductive part 109 carried by the movable part 106 disconnects from the contact switch 1081 on the control board 108, thus activating the sterilization element 200. The remaining water flows through the outlet a1041 into the water passage trough 1071 of the water passage 107. This water then contacts the back surface 202 of the sterilization lamp plate 201, carrying away water from the back surface 202. The heat of 02, the back of the lamp plate 202 is a single-sided aluminum substrate or copper substrate, and then the water flows up to the flow channel 205 and flows out through the water passage 310. Since a sealing ring 103 is provided between the water outlet 206 and the outer shell 300, the water can only flow to the sterilization zone 330 through the water outlet hole c2061 opened on the water outlet 206. At this time, the sterilization lamp plate 201 is in the open state. Therefore, the ultraviolet rays of the sterilization lamp plate 201 pass through the glass plate 203 and irradiate the sterilization zone 330 to sterilize the water. After sterilization, the water flows out along the water outlet 207 to the outside of the sterilization device. Since the lamp beads on the sterilization lamp plate 201 are all composed of high-power UVC LEDs, the sterilization treatment of the water can be completed in a few seconds.

[0041] Figure 7 In another embodiment of this application, the second diversion channel includes a sealing member 110 disposed in the middle of the germicidal lamp plate 201. A through hole is provided between the germicidal lamp plate 201 and the glass plate 203 to allow the sealing member 110 to pass through. The sealing member 110 is sealed with the hole provided between the germicidal lamp plate 201 and the glass plate 203. A water pipe 1101 is also sealed inside the sealing member 110, wherein a water outlet hole b1102 is provided on the bottom periphery of the water pipe 1101.

[0042] Furthermore, the seal 110 can be made of a material with sealing properties, such as rubber or silicone.

[0043] Figure 10In another embodiment of this application, the water flow direction b is the same. The water flow is divided into two parts. One part forms water pressure in the bottom 1051 of the chamber, causing the bottom 1051 of the chamber to squeeze the elastic switch to conduct the germicidal lamp plate 201. The other part carries away the heat from the back 202 of the lamp plate of the germicidal lamp plate 201 and enters the sterilization zone 330 through the water outlet hole b1102 on the water pipe 1101. The germicidal lamp plate 201 sterilizes the water, and then the water is discharged out of the sterilization device through the water outlet 207.

[0044] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
