Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a faucet with a sterilized water outlet. Background Technology

[0002] As people's demands for quality of life and healthy water increase, higher requirements are being placed on the cleanliness of household drinking and washing water. During the process of transporting tap water to users through pipes, bacteria may grow due to aging pipes, contaminated water tanks, and other reasons. While traditional filtration devices can remove some impurities, they are difficult to completely eliminate bacteria, viruses, and other microorganisms in the water. Ultraviolet (UV) sterilization technology is widely used in the water treatment field due to its advantages such as high efficiency, no secondary pollution, and no alteration of the water's physicochemical properties. Existing technologies also include products that integrate UV lamps into faucets, attempting to sterilize the water flow at the last moment before it flows out.

[0003] However, many designs place the ultraviolet lamps in a section of the inlet pipe. After the water is irradiated, it still needs to flow through a long, dark outlet channel before it can flow out. This dark channel can easily become a breeding ground for secondary bacterial growth, resulting in substandard water quality at the final outlet. Moreover, ultraviolet light has limited penetrating power in water. If the lamp is not positioned properly or the water flow pattern is not good, some water may not receive an effective dose of ultraviolet light, thus affecting the sterilization efficiency.

[0004] Furthermore, to ensure the effectiveness of ultraviolet (UV) sterilization, the water flow needs to be stable and concentrated across the irradiation area. However, many existing faucets have a loose water flow that easily splashes, which not only affects user comfort and causes water accumulation on the countertop, but also reflects the lack of concentrated water flow. This may affect the uniformity and dosage of UV irradiation, indirectly weakening the sterilization efficiency. While ordinary aerators on the market can prevent splashing to some extent, their main purpose is to mix in air to save water, not to be optimized for UV sterilization. Utility Model Content

[0005] The purpose of this utility model is to provide a faucet with a sterilizing outlet, which optimizes the setting position of the ultraviolet lamp to effectively sterilize the water flow at the very end of the outlet, and effectively constrains the water flow pattern to prevent splashing, making sterilization more uniform and thorough.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water tap with a sterilizing outlet, comprising a tap body and an inlet pipe disposed therein, wherein the outlet end of the tap body is provided with a water outlet assembly communicating with the inlet pipe, the water outlet assembly is provided with an ultraviolet lamp, the ultraviolet lamp is located at the junction of the water outlet assembly and the inlet pipe, and has a first irradiation direction toward the inlet pipe and a second irradiation direction toward the outlet end of the water outlet assembly, the first irradiation direction and the second irradiation direction being set at an angle, and the water outlet assembly is also provided with a flow guiding device, the flow guiding device being used to constrain the shape of the outflowing water.

[0007] By adopting the above technical solution, the setting position of the ultraviolet lamp is optimized, which effectively sterilizes the water flow at the very end of the outlet; the water flow pattern is effectively constrained to prevent splashing, which improves the user experience; in addition, the water flow is more concentrated, the uniformity of ultraviolet irradiation is improved, and sterilization is more thorough.

[0008] A further feature of this invention is that the ultraviolet lamp is located at the top of the inner cavity of the water outlet assembly, the flow guiding device is located at the bottom of the inner cavity of the water outlet assembly, and the water inlet pipe is connected to the side wall of the inner cavity of the water outlet assembly.

[0009] A further feature of this invention is that the water outlet assembly includes a detachably connected upper connector and a lower connector, the upper connector and the lower connector being vertically distributed, the ultraviolet lamp being disposed at the top of the inner cavity of the upper connector, the water inlet pipe being connected to the side wall of the inner cavity of the upper connector, and the flow guiding device being disposed at the bottom of the inner cavity of the lower connector. The water flow from the water inlet pipe passes sequentially through the upper connector and the lower connector, and flows out through the flow guiding device on the lower connector.

[0010] By adopting the above technical solution, the water in the inlet pipe can be disinfected by ultraviolet light as it flows to the outlet, making the disinfection and sterilization more thorough and effective. In addition, since the upper and lower connectors are independently set and detachably connected, the ultraviolet lamp on the upper connector and the flow guiding device on the lower connector can be inspected and maintained independently.

[0011] A further feature of this invention is that the flow guiding device includes a protruding post disposed within the lower connector and an arc-shaped baffle connected to the protruding post, wherein the arc-shaped baffle is inclined from one end of the lower connector toward the protruding post.

[0012] By adopting the above technical solution, the water flow will converge towards the center of the flow guide device under the guidance of the arc-shaped baffle, thereby achieving the effect of preventing splashing.

[0013] A further feature of this invention is that the water outlet assembly is perpendicular to the water inlet pipe.

[0014] By adopting the above technical solutions, ultraviolet irradiation becomes more uniform, and disinfection and sterilization become more thorough and effective.

[0015] A further feature of this invention is that: an annular rib is provided circumferentially on the inner wall of the upper connector, a sealing ring is provided on the annular rib, and the ultraviolet lamp extends into the annular rib and abuts against the sealing ring.

[0016] By adopting the above technical solution, it is possible to ensure that the ultraviolet lamp can simultaneously irradiate the inlet pipe and the outlet assembly, while also ensuring the sealing effect of the ultraviolet lamp.

[0017] A further feature of this invention is that the faucet body includes a horizontal section, and a control circuit board is fixedly installed within the horizontal section. The length direction of the control circuit board extends parallel to the axis of the horizontal section and is electrically connected to the ultraviolet lamp.

[0018] By adopting the above technical solution, the ultraviolet lamp and the control circuit board are connected at a short distance, avoiding complex wiring, ensuring circuit safety, and facilitating maintenance.

[0019] A further feature of this invention is that the water inlet pipe is located below the control circuit board, and the control circuit board and the water inlet pipe are arranged side by side vertically within a horizontal section, forming a circuit layer where the control circuit board is located and a water channel layer where the water inlet pipe is located.

[0020] By adopting the above technical solution, the layout is reasonable, and the circuit and water circuit do not interfere with each other, which facilitates maintenance; in addition, the signal line of the ultraviolet lamp is far away from the water circuit layer, so that the wiring of the ultraviolet lamp and the control circuit board does not need to pass through the water circuit, ensuring the safety of the circuit.

[0021] A further feature of this invention is that the faucet body includes a pipe and a cover disposed above the pipe. The cover is formed with an extension extending toward the pipe. The extension includes a protrusion protruding toward the side wall of the pipe. A locking hole is provided on the side wall of the pipe to accommodate the protrusion. The protrusion is snapped into the locking hole.

[0022] By adopting the above technical solution, the cover can be removed from the tube body by pressing the protrusion inside the card hole, making it easier to inspect the control circuit board inside the tube from above, and also making it easier to disassemble and replace the control circuit board.

[0023] A further feature of this invention is that the side wall of the tube body is provided with a guide slope extending to the card hole, and the guide slope is inclined toward the card hole.

[0024] By adopting the above technical solution, during the process of removing the cover, the protrusion rises along the guide slope, which increases the feel while reducing the resistance to removing the cover.

[0025] In summary, this utility model has the following beneficial effects: 1. An ultraviolet lamp is installed on the water outlet assembly. The ultraviolet lamp is located at the junction of the water outlet assembly and the water inlet pipe, and has a first irradiation direction towards the water inlet pipe and a second irradiation direction towards the water outlet assembly. Through the above design, the setting position of the ultraviolet lamp is optimized, and the water flow at the very end of the outlet is effectively sterilized. A flow guiding device is installed on the water outlet assembly to effectively constrain the water flow pattern, prevent splashing, improve the user experience, and make the water flow more concentrated, improve the uniformity of ultraviolet irradiation, and make sterilization more thorough.

[0026] 2. The faucet body includes a horizontal section, within which a control circuit board is fixedly installed. The length of the control circuit board extends parallel to the axis of the horizontal section and is electrically connected to the ultraviolet lamp. The short-distance connection between the ultraviolet lamp and the control circuit board avoids complex wiring, ensures circuit safety, and facilitates maintenance. The control circuit board and the water inlet pipe are arranged vertically side by side within the horizontal section, forming a layered structure in the vertical direction. The layout is reasonable, and the circuit and water circuit do not interfere with each other, facilitating maintenance. In addition, the signal line of the ultraviolet lamp is far away from the water circuit layer, so that the wiring between the ultraviolet lamp and the control circuit board does not need to pass through the water circuit, ensuring circuit safety.

[0027] 3. The casing is formed with an extension extending towards the tube body. The extension includes a protrusion protruding towards the side wall of the tube body. A locking hole is formed on the side wall of the tube body to accommodate the protrusion. The protrusion is snapped into the locking hole. By pressing the protrusion in the locking hole, the casing is released from the tube body and can be removed. This facilitates direct access to the control circuit board inside the tube body for maintenance and also facilitates the disassembly and replacement of the control circuit board. The side wall of the tube body is provided with a guide slope extending to the locking hole. The guide slope is inclined towards the locking hole. When the protrusion in the locking hole is pressed, the protrusion rises along the guide slope during the removal of the casing, which increases the feel and reduces the resistance when removing the casing.

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] A type of faucet with a sterilizing spout, such as Figure 1-5 As shown, the device includes a faucet body 1 and an inlet pipe 2 disposed inside it. The outlet end of the faucet body 1 is provided with a water outlet assembly 3 that communicates with the inlet pipe 2. The inlet pipe 2 and the water outlet assembly 3 are snapped together. An ultraviolet lamp 4 is disposed on the water outlet assembly 3. The ultraviolet lamp 4 is located at the junction of the water outlet assembly 3 and the inlet pipe 2, and has a first irradiation direction towards the inlet pipe 2 and a second irradiation direction towards the outlet end of the water outlet assembly 3 (i.e., the outlet end of the faucet body 1). The first and second irradiation directions are formed due to obstruction by the inner wall of the water outlet assembly 3. The component 3 is set at an angle to the water inlet pipe 2, so the first irradiation direction and the second irradiation direction are also set at an angle. Through the above design, the setting position of the ultraviolet lamp 4 is optimized, and the water flow at the very end of the outlet is effectively sterilized. The water outlet assembly 3 is also provided with a flow guiding device 5. The flow guiding device 5 is preferably set at the water outlet end of the water outlet assembly 3, that is, the water outlet end of the faucet body 1. The water in the water inlet pipe 2 is discharged after passing through the flow guiding device 5. Through the above design, the water flow pattern is effectively constrained to prevent splashing, which improves the user experience. In addition, the water flow is more concentrated, the uniformity of ultraviolet irradiation is improved, and the sterilization is more thorough.

[0036] Preferably, the ultraviolet lamp 4 is disposed at the top of the inner cavity of the water outlet assembly 3, the flow guiding device 5 is disposed at the bottom of the inner cavity of the water outlet assembly 3, and the water inlet pipe 2 is connected to the side wall of the inner cavity of the water outlet assembly 3.

[0037] Preferably, the water outlet assembly 3 includes a detachably connected upper connector 31 and a lower connector 32, preferably threaded. The upper connector 31 and the lower connector 32 are vertically distributed. The ultraviolet lamp 4 is disposed at the top of the inner cavity of the upper connector 31, the water inlet pipe 2 is connected to the side wall of the inner cavity of the upper connector 31, and the flow guiding device 5 is disposed at the bottom of the inner cavity of the lower connector 32. The water flow from the water inlet pipe 2 passes sequentially through the upper connector 31 and the lower connector 32, and flows out through the flow guiding device 5 on the lower connector 32. Through the above design, the ultraviolet lamp 4 irradiates the upper connector 31 and the lower connector 32 in the vertical direction (i.e., the first irradiation direction). 2. The flow guiding device 5 irradiates the upper connector 31 and the water inlet pipe 2 in the direction of the inner wall of the upper connector 31 (i.e., the second irradiation direction), so that the water in the water inlet pipe 2 can be disinfected by ultraviolet irradiation during the process of flowing to the water outlet, making the disinfection and sterilization more thorough and effective. In addition, since the upper connector 31 and the lower connector 32 are independently set and detachably connected, the ultraviolet lamp 4 on the upper connector 31 and the flow guiding device 5 on the lower connector 32 can be independently inspected and maintained. The upper connector 31 and the ultraviolet lamp 4 and the lower connector 32 and the flow guiding device 5 can all be set as an integrated connection, so only the upper connector 31 and the lower connector 32 need to be disassembled to replace the ultraviolet lamp 4 or the flow guiding device 5.

[0038] Preferably, the flow guiding device 5 is cylindrical and includes a protruding post 51 disposed in the lower connector 32 and an arc-shaped baffle 52 connected to the protruding post 51. The protruding post 51 is located at the center of the flow guiding device 5 and protrudes towards the upper connector 31. After entering the lower connector 32, the water flow enters the arc-shaped baffle 52 around the protruding post 51 under the obstruction of the protruding post 51. The arc-shaped baffle 52 is inclined from one end of the lower connector 32 towards the protruding post 51, that is, inclined towards the center of the flow guiding device 5. Under the guidance of the arc-shaped baffle 52, the water flow will converge towards the center of the flow guiding device 5, thereby achieving the effect of preventing splashing.

[0039] Preferably, the water outlet assembly 3 and the water inlet pipe 2 are vertically distributed. The ultraviolet lamp 4 irradiates the upper connector 31, lower connector 32, and flow guiding device 5 in the vertical direction (i.e., the first irradiation direction), and irradiates the upper connector 31 and water inlet pipe 2 in the horizontal direction (i.e., the second irradiation direction). Through the vertically distributed water outlet assembly 3 and water inlet pipe 2, the ultraviolet irradiation is more uniform, and the disinfection and sterilization are more thorough and effective.

[0040] Preferably, the inner wall of the upper connector 31 is provided with an annular rib 311, and a sealing ring 312 is provided on the annular rib 311. The ultraviolet lamp 4 extends into the annular rib 311 and abuts against the sealing ring 312, which ensures that the ultraviolet lamp 4 can simultaneously irradiate the water inlet pipe 2 and the water outlet assembly 3, and also ensures the sealing effect of the ultraviolet lamp 4.

[0041] Preferably, the faucet body 1 includes a horizontal section 11, within which a control circuit board 111 is fixedly disposed. The length direction of the control circuit board 111 extends parallel to the axis of the horizontal section 11 and is electrically connected to the ultraviolet lamp 4. The control circuit board 111 is a slender rectangular flat plate and is fixedly connected to the inner wall of the horizontal section 11. The short-distance connection between the ultraviolet lamp 4 and the control circuit board 111 avoids complex wiring, ensures circuit safety, and facilitates maintenance.

[0042] Preferably, the water inlet pipe 2 is located below the control circuit board 111. The control circuit board 111 and the water inlet pipe 2 are arranged side by side vertically within the horizontal section 11, forming a circuit layer 110 where the control circuit board 111 is located and a water channel layer 210 where the water inlet pipe 2 is located. The control circuit board 111 and the water inlet pipe 2 form a vertically layered structure, with the circuit layer 110 on the upper layer and the water channel layer 210 on the lower layer. This layout is reasonable, and the circuit and water channels do not interfere with each other, facilitating maintenance. In addition, the signal line of the ultraviolet lamp 4 is far away from the water channel layer 210, so that the wiring between the ultraviolet lamp 4 and the control circuit board 111 does not need to pass through the water channel, ensuring circuit safety.

[0043] Preferably, the faucet body 1 includes a pipe body 12 and a cover 13 disposed above the pipe body 12. The cover 13 is formed with an extension portion 131 extending toward the pipe body 12. The extension portion 131 includes a protrusion 132 protruding toward the side wall of the pipe body 12. A locking hole 121 is provided on the side wall of the pipe body 12 to accommodate the protrusion 132. The protrusion 132 is snapped into the locking hole 121. By pressing the protrusion 132 inside the locking hole 121, the cover 13 is released from the tube body 12 and can be removed. This allows for direct access to the control circuit board 111 inside the tube body 12 for maintenance and easy disassembly and replacement of the control circuit board 111. Preferably, the cover 13 is removed by creating an operating hole 123 on the tube body 12 below the locking hole 121. After pressing the locking hole 121, any rod-shaped tool can be inserted into the operating hole 123 and pressed upwards towards the protrusion 132 to pop out the cover 13. The operating hole 123 can also be used to observe the condition inside the faucet body 1 to check for leaks, corrosion, etc. As a preferred embodiment, after removing the control circuit board 111, the water outlet assembly 3 and the water pipe are in an open state, allowing the operator to repair and replace them.

[0044] Preferably, the side wall of the tube body 12 is provided with a guide slope 122 extending to the locking hole 121, and the guide slope 122 is inclined toward the locking hole 121. When the protrusion 132 in the locking hole 121 is pressed, the protrusion 132 rises along the guide slope 122 during the removal of the cover 13, which increases the feel and reduces the resistance to removing the cover 13.

[0045] Preferably, a pressure plate 6 is provided inside the faucet body 1, and the bottom of the pressure plate 6 abuts against the top of the water inlet pipe 2. When hot water is introduced into the water inlet pipe 2, the water inlet pipe 2 will expand slightly and its diameter will increase due to thermal expansion and contraction. By setting the pressure plate 6, the risk of the water inlet pipe 2 being twisted, cracked or damaged due to thermal stress is reduced, and the shaking and friction of the water inlet pipe 2 are reduced, thus extending its service life.

[0046] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
