Drinking water equipment is usually equipped with a water tank; water from the purifier is first filled into the tank and then drawn from it when needed. However, when the user does not use the equipment for a long time or after the machine has been in use for an extended period, bacteria or algae may grow in the water tank. These substances can affect the taste and safety of drinking water. To solve this problem, related technologies typically install ultraviolet (UV) lamps in the water tank to inhibit bacteria. The areas irradiated by the UV lamps are effective at inhibiting bacteria; however, due to the irregular shape of the water tank, there are blind spots where UV light cannot reach, and areas not reached by the UV lamps still pose a risk of bacterial growth after prolonged use.

Drinking water equipment is usually equipped with a water tank; water from the purifier is first filled into the tank and then drawn from it when needed. However, when the user does not use the equipment for a long time or after the machine has been in use for an extended period, bacteria or algae may grow in the water tank. These substances can affect the taste and safety of drinking water. To solve this problem, related technologies typically install ultraviolet (UV) lamps in the water tank to inhibit bacteria. The areas irradiated by the UV lamps are effective at inhibiting bacteria; however, due to the irregular shape of the water tank, there are blind spots where UV light cannot reach, and areas not reached by the UV lamps still pose a risk of bacterial growth after prolonged use.

[0107] In this embodiment, the controller is communicatively connected to the water quality sensor and the ultraviolet lamp 2, and can control the irradiation intensity of the ultraviolet lamp 2 according to the water quality parameters detected by the water quality sensor, thereby improving water quality more efficiently.

[0108] In one specific embodiment, when the water quality sensor detects a high concentration of bacteria in the water tank 3, the irradiation intensity of the ultraviolet lamp 2 is increased; when the water quality is good, the irradiation intensity of the ultraviolet lamp 2 is reduced, thereby saving energy.

[0109] In one specific embodiment, the controller adjusts the output power of the ultraviolet lamp 2 through PWM modulation, thereby adjusting the irradiation intensity of the ultraviolet lamp 2. The power adjustment range of the ultraviolet lamp 2 is 50W to 150W, and the adjustment accuracy is controlled within 1W.

[0110] According to an embodiment of the present invention, in a fourth aspect, a water purification device is provided, comprising: the water tank assembly provided in the above embodiments.

[0111] In this embodiment, the light-receiving unit 101 is connected to the ultraviolet lamp 2, thus receiving the ultraviolet light emitted by the ultraviolet lamp 2. The light guide tube 102 is connected to the light-receiving unit 101, so the ultraviolet light, after passing through the light-receiving unit 101, is transmitted into the light guide tube 102, where it is transmitted and can also pass through the light guide tube 102 to irradiate outwards. Since the light guide tube 102 is connected to multiple first branch tubes 103, the ultraviolet light can also irradiate outwards through the first branch tubes 103. The light irradiated from the light guide tube 102 and the ultraviolet light irradiated from the first branch tubes 103 can achieve ultraviolet light irradiation from various angles. Therefore, it can irradiate and sterilize the inside of the water tank 3 from all directions, avoiding the risk of bacterial growth due to incomplete irradiation. This water purification device can ensure the water quality inside the water tank 3.

[0112] It should be noted that the water purification equipment also includes the structures found in conventional water purification equipment, such as filter components, pipelines, and water pumps, which will not be described in detail in this embodiment.

[0113] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
