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.

[0029] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example 1: Figure 1-2 As shown, the present invention provides a technical solution: a water outlet nozzle, comprising a water outlet cavity 100, wherein the water outlet cavity 100 is respectively connected to a water inlet pipe 200 and a water outlet pipe 300,

[0032] The water outlet cavity 100 includes a first chamber 110, a second chamber 120, a third chamber 130 and a steam outlet chamber 160 which are sequentially connected based on a water inlet pipe 200. Hot water flows into the first chamber 110 from the water inlet pipe 200, and flows into the second chamber 120 from a water inlet notch 140 provided at the bottom of the first chamber 110. At this time, part of the steam generated by the hot water is discharged from the steam outlet pipe 150, and the other part of the steam enters the steam outlet chamber 160 from the second chamber 120 along with the hot water, and condenses in the steam outlet chamber 160 to generate condensed water, which moves downward to the outlet for discharge;

[0033] Hot water enters the third chamber 130 through the guide port 170 at the bottom of the second chamber 120. A UV sterilization lamp 180 is provided at the top of the third chamber 130. The hot water sterilized by the UV sterilization lamp 180 is discharged from the water outlet pipe 300. The distance between the water outlet pipe 300 and the guide port 170 in the third chamber 130 forms a height difference. When the water flows upward based on the height difference, it is irradiated by the UV sterilization lamp 180 for sterilization.

[0035] The water inlet pipe 200 includes a normal temperature water inlet end and a temperature control water inlet end. Based on the pre-set temperature control water, the water flows into the first chamber 110 through the temperature control water inlet end, and then the water flow rate and water flow velocity of the normal temperature water inlet end and the temperature control water inlet end are controlled by a control valve to calculate the water temperature entering the first chamber 110.

[0036] The UV sterilization lamp 180 is fixed in the lamp trough 400, and the lamp trough 400 is installed in the water outlet cavity 100 through a sealing component combination and is sealed and connected through a sealing cover 500; in actual application, the UV sterilization lamp 180 used in the water dispenser itself has the functions of waterproof and high temperature resistance, but in long-term use, the UV sterilization lamp 180 is a consumable. In order to ensure the service life of the UV sterilization lamp 180 and increase the user experience, this embodiment provides a protective component for the UV sterilization lamp 180, and the UV sterilization lamp 180 is installed in the lamp trough 400. If the UV sterilization lamp 180 fails in the later stage, the UV sterilization lamp 180 can be directly replaced by unsealing the sealing cover 500; and since the lamp trough 400 is under the impact of hot water for a long time, experiments have shown that the loss here is relatively large, so the lamp trough 400 can be installed in a combined manner, and the lamp trough 400 can be replaced at any time.

[0037] The lamp trough 400 can also be integrated with the water outlet cavity 100. Based on the setting of the internal components of the water outlet cavity 100, a fixed diversion route is provided to flow hot water from the water inlet pipe 100 to the water outlet pipe 300; reinforcing components such as reinforcing ribs are added during the setting of the lamp trough 400.

[0038] The portion of the lamp trough 400 corresponding to the water outlet pipe 300 is a transparent irradiation area, and an irradiation gap is provided between the transparent irradiation area and the water outlet pipe 300, so as to reduce the impact of hot water on the transparent irradiation area and increase the service life of the lamp trough 400 to a certain extent.

[0039] Example 2: Figure 1 As shown, the part not described in detail in this embodiment is as shown in Example 1. The present invention provides a technical solution: a method for controlling a water outlet, comprising the following steps:

[0040] Step S1: pre-enter the temperature control information of the water dispenser, the temperature control information includes the heating component order number and the heating level barcode, the heating level barcode is associated with the product model and product control parameters corresponding to the current heating component; the associated temperature control information is stored in the storage module and displayed on the operation panel, the outlet water temperature is set based on the operation panel, the outlet water temperature is matched with the corresponding temperature control information, and the water inlet temperature of the water inlet pipe 200 is regulated based on the temperature control information;

[0041] Step S2: hot water is input from the water inlet pipe 200 into the water outlet cavity 100 through a control valve, and the hot water is introduced into the water outlet cavity 100 based on the flow path and output from the water outlet pipe 300 .
