Those skilled in the art can understand the purpose, features, and effects of this utility model from the content disclosed in this specification. It should be noted that this utility model can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the inventive point of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustrative purposes only and are not depictions based on actual dimensions. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the claims of this utility model. The explanation is as follows:

[0018] like Figure 1 and Figure 2 As shown, the sterilizing water dispenser 1 of this utility model embodiment includes: a housing 10, a water outlet module 20, a water supply module 30, a water tank 40, a sterilization module 50, a control module 60, and a power supply module 70. The power supply module 70 can be connected to the control module 60 via mains power to provide driving power for each component.

[0019] A water outlet module 20 is disposed within the housing 10 to provide sterilized drinking water to a cup (not shown) on a cup holder 110 of the housing 10. In this embodiment, the water outlet module 20 may further include a water-air separator 210 and at least one second ultraviolet sterilization light source 220. The second ultraviolet sterilization light source 220 is electrically connected to the control module 60 and provides ultraviolet light to effectively perform secondary sterilization on the drinking water after instantaneous heating treatment, thereby improving the safety of the drinking water. The water-air separator 210 can separate the sterilized drinking water from the steam. In one embodiment, the water outlet module 20 may be provided with one or more water outlets 230 in the water-air separator 210 to provide sterilized drinking water.

[0020] The water supply module 30 is disposed within the housing 10 and communicates with the water outlet module 20. In this embodiment, the water supply module 30 may include a water supply pipe 310, a one-way valve 320, a flow meter 330, a water pump 340, and an instant heating module 350. The water supply pipe 310 is connected between the water tank 40 and the water outlet module 20 to deliver sterilized drinking water stored in the water tank 40; the one-way valve 320 is connected between the water tank 40 and the water supply pipe 310 to prevent the drinking water in the water supply pipe 310 from flowing back into the water tank 40; the flow meter 330 is used to measure and monitor the water flow rate and cumulative flow information; the water pump 340 pressurizes the drinking water stored in the water tank 40 and delivers the sterilized drinking water along the water supply pipe 310 to the water outlet module 20; the instant heating module 350 includes a heating unit (not shown) and a temperature sensing component (not shown) to control the heated water temperature. A flow meter 330, a water pump 340, and an instant heating module 350 are sequentially mounted on a water supply pipe 310 and electrically connected to a control module 60. In this embodiment, the heating unit of the instant heating module 350 may include a heating element, a thin-film heating tube, a rare-earth thick-film heater, a stainless steel nano-rare-earth heating tube, or a combination thereof, which is not limited in this utility model.

[0021] Water tank 40 is installed on housing 10 and connected to water supply module 30. Water tank 40 is made of ultraviolet-permeable material so that ultraviolet rays can effectively penetrate water tank 40 and sterilize the water inside water tank 40.

[0022] Furthermore, in this embodiment, the water tank 40 may be designed as a detachable unit, with a handle 410 for easy lifting by the user. Additionally, to ensure the purity of the drinking water, a replaceable filter element 420 is installed inside the water tank 40 before the one-way valve 320 to effectively filter impurities from the water.

[0023] The sterilization module 50 is disposed in the housing 10 and includes at least one first ultraviolet sterilization light source 520. The first ultraviolet sterilization light source 520 irradiates the interior of the water tank 40, so that the drinking water stored in the water tank 40 can be sterilized in all directions. In this embodiment, the sterilization module includes at least one lens body 530, which is disposed in relation to the first ultraviolet sterilization light source 520 and is made of an ultraviolet-transmitting material. In this embodiment, the light beam emitted by the first ultraviolet sterilization light source can be collimated into a collimated ultraviolet beam by the lens body 530. The collimated ultraviolet beam can effectively focus and enhance the ultraviolet beam, so that the collimated ultraviolet beam can penetrate evenly and comprehensively into the interior of the water tank 40, thereby improving the sterilization efficiency of the drinking water. In this embodiment, the sterilization module 50 may also be provided with a base 510, on which the first ultraviolet sterilization light source 520 can be installed. The base 510 can be installed in a suitable position in the housing 10 to provide stable support and a good heat dissipation environment. In this embodiment, the sterilization module 50 is disposed within the housing 10 and emits ultraviolet light from the first ultraviolet sterilization light source 520 to the lens 530 to sterilize the drinking water stored in the water tank 40. The sterilization module 50 can be disposed on the top, front, or rear side of the water tank 40, etc., so that the sterilization module 50 can irradiate the drinking water stored in the water tank 40 with ultraviolet light for sterilization. In addition, the sterilization module 50 can be electrically connected to the power supply module 70 via a probe to provide driving power.

[0024] A control module 60 is disposed in the housing 10 and electrically connected to the first ultraviolet germicidal light source 520 to control the opening and closing of the first ultraviolet germicidal light source 520. A power supply module 70 is disposed in the housing 10 and electrically connected to the control module 60 to provide driving power to each component. In this embodiment, the control module 60 may include a human-machine interface 610 and an electronic control board 620. The human-machine interface 610 can be used to allow users to input operation commands and view the operating status of the equipment. The electronic control board 620 can receive and process operation commands from the human-machine interface 610, and is electrically connected to and controls the operation of the first ultraviolet germicidal light source 520, the second ultraviolet germicidal light source 220, the water pump 340, the flow meter 330, and the instant heating module 350. In this embodiment, the human-machine interface 610 may include, for example, a touch panel, a button panel, or a combination thereof.

[0025] Furthermore, such as Figure 1 and Figure 2As shown, in this embodiment, the water tank 40 and the lens body 530 can be made of hydrogenated styrene-butadiene-styrene cyclic block copolymer (CBC). This can avoid problems such as aging, embrittlement, or yellowing caused by prolonged exposure of the water tank 40 and the lens body 530 to the first ultraviolet germicidal light source 520, and also avoid the problem of reduced light-gathering effect of the lens body 530. This can extend the service life of the water tank 40 and the lens body 530 and reduce defects caused by the different shrinkage rates of different plastics.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the sterilizing water dispenser 1 can be electrically connected to and monitor the remaining lifespan of the replaceable filter element 420 via the electronic control board 620. Additionally, in one embodiment of this application, the electronic control board 620 can measure the cumulative flow of drinking water from the water tank 40 to the water outlet module 20 via the flow meter 330 to estimate the lifespan of the replaceable filter element 420. In another embodiment of this application, the electronic control board 620 can be connected or coupled to a timer (not shown), which can calculate the cumulative usage hours based on the installation start time of the replaceable filter element 420 to estimate its lifespan.
