Description

Technical Field

[0001] The invention belongs to the technical field of water purification equipment, and in particular relates to an induction-type ultraviolet sterilization faucet with a prompt light. Background Art

[0002] In the prior art, faucets with built-in ultraviolet sterilization cylinders are usually equipped with a manual opening handle. When the handle is rotated to open the faucet, the Hall element, reed switch or conductive silicone thimble set in the handle is used to open the faucet and release water while starting the ultraviolet sterilization lamp for sterilization. It has the advantage of ultraviolet sterilization and water purification at the end of the water outlet. However, it has the following shortcomings: the way the handle is opened and closed is not very intelligent, and it is not suitable for specific scenarios where it is inconvenient to use hands to operate, such as washing hands and disinfecting before surgery. If you touch the handle again to turn off the water after washing your hands, it will cause re-contamination; there is no status indicator light or the status indicator light is a small dot, and the user cannot clearly know whether the built-in ultraviolet sterilization cylinder is in working condition. Summary of the invention

[0003] The purpose of the present invention is to provide an induction type ultraviolet sterilizing faucet with a prompt light, aiming to overcome the shortcomings of the existing ultraviolet sterilizing faucet that it is opened and closed by twisting a traditional handle and lacks a prompt light.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: an induction type ultraviolet sterilization faucet with a prompt light, comprising a threaded straight barrel and a water outlet straight barrel, the threaded straight barrel connecting the water outlet straight barrel at the front end and the water inlet pipe at the rear end, the water inlet pipe is provided with a solenoid valve box, the rear end of the threaded straight barrel is threadedly connected with a clamping nut, the front end is sleeved with a lamp ring seat, the lamp ring seat is provided with a ring-shaped light-emitting circuit board, the front end of the water outlet straight barrel is provided with a water outlet end cover, the lower side of the water outlet end cover is provided with a water outlet protrusion, the upper rear side of the water outlet end cover is connected with the front end of the built-in water outlet pipe, and the lower part is fixed with an infrared sensor, the bottom front side of the water outlet straight barrel is provided with through holes one and two through holes corresponding to the water outlet protrusion and the infrared sensor, an ultraviolet sterilization barrel is also provided in the water outlet straight barrel, and the water outlet front end of the ultraviolet sterilization barrel is connected with the rear end of the built-in water outlet pipe.

[0005] Based on the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, the lamp ring seat includes a first annular cover body and a second annular cover body which can form an annular inner cavity when covered with each other, the inner ring of the first annular cover body is sleeved and fixed on the outside of the threaded straight cylinder, and the second annular cover body can be opened and closed to cover the front side of the first annular cover body, and the light-emitting circuit board is arranged in the annular inner cavity.

[0007] The beneficial effect of adopting the above further solution is that the lamp ring seat of the above structure is relatively simple in structure and has an openable and closable first annular cover, which facilitates the installation, inspection, maintenance and replacement of the internal light-emitting circuit board.

[0008] Furthermore, the second annular cover is made of a transparent or translucent material.

[0009] The beneficial effect of adopting the above further scheme is that the light emitted by the light-emitting circuit board can be transmitted through the second annular cover body, which is beautiful and serves as an obvious prompt. For example, when the faucet is not discharging water, the light-emitting circuit board does not emit light or emits weak white light of a certain intensity. Preferably, it emits weak white light, which has the advantage of saving electricity and serving as a prompt for the position of the faucet at night or in a darker environment. When water is flowing out of the faucet and the ultraviolet lamp in the ultraviolet sterilization tube is working normally, the light-emitting circuit board emits blue light or purple light, indicating that the water is clean water sterilized by the ultraviolet sterilization tube, and also indicating that the ultraviolet sterilization tube can work normally. When water is flowing out of the faucet and the ultraviolet sterilization tube cannot work normally (that is, no ultraviolet light is emitted), the light-emitting circuit board emits red light, indicating that the ultraviolet sterilization tube has a fault so that the staff can perform maintenance in time.

[0010] Furthermore, a water flow sensing switch is also provided in the water inlet pipe or the water outlet cylinder, and the water flow sensing switch can control the start or shut down of the ultraviolet sterilization cylinder.

[0011] The beneficial effect of adopting the above further scheme is that by controlling the opening and closing of the ultraviolet sterilization cylinder through the water flow sensing switch, it can effectively ensure that the ultraviolet sterilization cylinder is started for sterilization when and only when there is water flowing, thereby avoiding the ultraviolet sterilization cylinder from sterilizing stagnant water for a long time, causing energy waste, damage to the ultraviolet sterilization cylinder and other problems.

[0012] Furthermore, an ultraviolet sensor is also arranged in the water outlet cylinder.

[0013] The beneficial effect of adopting the above further solution is that the ultraviolet sensor can monitor the purple-red line emitted by the ultraviolet sterilization cylinder in real time, so as to better judge the working status of the ultraviolet sterilization cylinder.

[0014] Furthermore, the light-emitting circuit board, the ultraviolet sterilization cylinder, the infrared sensor and the solenoid valve box are electrically connected to the controller via data lines respectively.

[0015] The beneficial effect of adopting the above further solution is that the controller can control the working states of the solenoid valve box, the ultraviolet sterilization cylinder and the light-emitting circuit board according to the signal detected by the infrared sensor.

[0016] Technical effects and advantages of the present invention:

[0017] The faucet provided by the present invention has components such as an infrared sensor, a solenoid valve box, a lamp ring seat and a built-in ultraviolet sterilization tube, and has multiple functions such as inductive water discharge and shutoff, sterilization and purification by the built-in ultraviolet sterilization tube during water discharge, and prompting of different working states of the ultraviolet sterilization tube through the lamp ring seat; in addition to the function of the built-in annular light-emitting circuit board, the lamp ring seat is also a fixed component that facilitates the installation of the faucet, and the lamp ring seat works together with the clamping nut to facilitate the clamping and fixing of the faucet on the plate-like component with the mounting hole; the overall structure is compact, comprehensive in functions, beautiful in appearance and has better applicability.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, if terms indicating orientation such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figures 1 to 4 As shown, the present invention provides an induction-type ultraviolet sterilizing faucet with a prompt light, which comprises a threaded straight cylinder 1 and a water outlet straight cylinder 2, wherein the threaded straight cylinder 1 is connected to the water outlet straight cylinder 2 at the front end and the water inlet pipe at the rear end, and the water inlet pipe is provided with a solenoid valve box, the rear end of the threaded straight cylinder 1 is threadedly connected with a clamping nut 3, and the front end is sleeved with a lamp ring seat 4, and a ring-shaped light-emitting circuit board 5 is arranged in the lamp ring seat 4, and the front end of the water outlet straight cylinder 2 is provided with a water outlet end cover 6, and the lower side of the water outlet end cover 6 is provided with a water outlet protrusion 7, the upper rear side of the water outlet end cover 6 is connected with the front end of the built-in water outlet pipe 8, and an infrared sensor 9 is fixed to the lower part, and the bottom front side of the water outlet straight cylinder 2 is provided with a through hole 10 and a through hole 2 11 corresponding to the water outlet protrusion 7 and the infrared sensor 9 at intervals, and an ultraviolet sterilizing cylinder is also arranged in the water outlet straight cylinder 2, and the water outlet front end of the ultraviolet sterilizing cylinder is connected with the rear end of the built-in water outlet pipe 8.

[0027] It is understandable that the infrared sensor can detect whether someone reaches out to the water outlet of the water outlet tube. If so, it sends a signal to the control component (controller) to control the solenoid valve box to start and open the faucet to discharge water. At the same time, the control component can also control the ultraviolet sterilization tube and the lamp ring seat to switch working states, such as controlling the ultraviolet sterilization tube to start and the lamp ring seat to emit blue light. The lamp ring seat is preferably set to emit multiple different colors of light so that different colors of light can be used to indicate different content.

[0028] It should be noted that the built-in ultraviolet sterilization cylinder in the water outlet cylinder is a prior art known to those skilled in the art, and its structure and installation method can refer to a sterilizing faucet disclosed in the existing patent CN109253296.

[0029] In one embodiment of the present invention, Figure 4 As shown, the lamp ring seat 4 includes a first annular cover 12 and a second annular cover 13 that can form an annular inner cavity when they are covered with each other. The inner ring of the first annular cover 12 is sleeved and fixed outside the threaded straight tube 1, and the second annular cover 13 can be opened and closed to cover the front side of the first annular cover 12, and the light-emitting circuit board 5 is arranged in the annular inner cavity. The second annular cover 13 is made of transparent or translucent material, preferably polypropylene, polycarbonate, polyoxymethylene or organic glass.

[0030] It is understandable that the first annular cover body can be integrally formed with the threaded straight cylinder or threadedly connected. The second annular cover body can be connected to the first annular cover body in a snap-fitting manner, a threaded connection manner or other common manners.

[0031] In one embodiment of the present invention, a water flow sensor switch is further provided in the water inlet pipe or the water outlet cylinder 2, and the water flow sensor switch can control the start or shut down of the ultraviolet sterilization cylinder.

[0032] It should be noted that in the above embodiment, after adding a water flow sensing switch, the start and stop of the ultraviolet sterilization cylinder is no longer directly controlled by a control component connected to the infrared sensor signal, but is controlled by the water flow sensing switch. When water flows through, the water flow sensing switch gives a signal to the controller corresponding to the ultraviolet sterilization cylinder and controls the ultraviolet sterilization cylinder to start. When the water flow stops, the water flow sensing switch gives another signal to the controller corresponding to the ultraviolet sterilization cylinder and controls the ultraviolet sterilization cylinder to shut down. The logic is simpler and the control is more direct.

[0033] In one embodiment of the present invention, an ultraviolet sensor is also provided in the water outlet cylinder 2 .

[0034] It should be noted that, in the above embodiment, after the ultraviolet sensor is added, the ultraviolet rays escaping when the ultraviolet sterilization tube is started can be detected by the ultraviolet sensor, thereby giving a signal that the ultraviolet sterilization tube can work normally, making it easier to know the working status of the ultraviolet sterilization tube more accurately, so that the luminous circuit board prompt function of the lamp ring holder is more accurate.

[0035] In one embodiment of the present invention, the light-emitting circuit board 5 , the ultraviolet sterilization tube, the infrared sensor 9 and the solenoid valve box are electrically connected to the controller via data lines 14 , respectively.

[0036] In the above embodiment, the light-emitting circuit board, the ultraviolet sterilization tube, the infrared sensor and the solenoid valve box are electrically connected to the same controller respectively, and the working state switching of each component is controlled by one controller. The structure is relatively simple, which is conducive to cost saving.

[0037] The basic principle of the present invention is briefly described as follows:

[0038] The infrared sensor near the water outlet nozzle below the water outlet cylinder can sense whether there is a human hand approaching. If so, it will send a signal to the control component, thereby starting the solenoid valve box to open the water outlet. At the same time, the control component also starts the ultraviolet sterilization cylinder built into the water outlet cylinder for sterilization. When the ultraviolet sterilization cylinder is started, the light-emitting circuit board in the lamp ring holder also synchronously switches the light color to blue or purple. After starting, all of the above components have the function of automatically shutting down after a period of delayed continuous work. When no water is discharged, the control component ensures that the light-emitting circuit board in the lamp ring holder emits a faint white or yellow light. When water is discharged and the ultraviolet sterilization cylinder cannot be started, the control component can ensure that the light-emitting circuit board in the lamp ring holder emits a continuous red light or a continuously flashing red light, indicating an internal fault.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
