[0026] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See Figure 1-4The present invention provides a water kettle with a constant water output temperature, comprising an inner liner 1 for boiling water and a centrifugal pump 2 disposed below the inner liner 1. The centrifugal pump 2 is provided with a water inlet port 21 and a water outlet port 22. The water inlet port 21 of the centrifugal pump 2 is connected to the interior of the inner liner 1 via a pipeline, and the water outlet port 22 of the centrifugal pump 2 is connected to a water outlet pipe 3. Specifically, the water outlet pipe 3 is a vertically arranged water outlet pipe body 31. The bottom of the water outlet pipe body 31 is bent toward the side close to the centrifugal pump 2 to form a water inlet pipe portion 32, which is connected to the water outlet port 22 of the centrifugal pump 2; the top of the water outlet pipe body 31 is bent toward the side away from the inner liner 1 to form a water outlet pipe portion 33. Furthermore, the utility model includes a ceramic heater 4 and an NTC temperature probe 5. The ceramic heater 4 is sleeved around the outer periphery of the water inlet pipe portion 32 to achieve heating, and the NTC temperature probe 5 abuts against the outer wall of the water inlet pipe portion 32 to detect temperature.

[0030] Therefore, by arranging a ceramic heating body 4 on the outer periphery of the water inlet pipe 32, the ceramic heating body 4 generates heat when energized, and the heat is transferred to the water outlet pipe 3 and heats the water inside it; by arranging an NTC temperature measuring probe 5 on the outer wall of the water inlet pipe 32, heating can be stopped when it is detected that the temperature of the water inlet pipe 32 reaches the preset temperature. At this time, the temperature of the water in the water outlet pipe 3 is consistent with the temperature of the water in the inner tank 1, so that the temperature of the output water is consistent with the preset temperature, thereby ensuring the brewing quality.

[0031] In addition, by putting the ceramic heating body 4 on the water inlet pipe 32, it can be ensured that when the water level in the water outlet pipe 3 is at the lowest position, the water can still be heated, preventing the water outlet pipe 3 from drying out, thereby extending the service life of the water outlet pipe 3.

[0032] In the embodiment of the present utility model, this outlet pipe 3 is made of stainless steel. Of course, in other embodiments, it can also be made of PP material, which is not limited here.

[0033] Furthermore, a fixing sleeve 6 is also included which is sleeved on the outer periphery of the ceramic heating body 4. The fixing sleeve 6 wraps and fixes the ceramic heating body 4 and the NTC temperature probe 5. Thus, the fixing sleeve 6 is used for wrapping and fixing, thereby facilitating assembly and disassembly and achieving higher efficiency.

[0034] Preferably, the fixing sleeve 6 is made of silicone material.

[0035] Furthermore, the water bottle further comprises a sealing sleeve 7, which is respectively sleeved on the water outlet interface 22 and the outer periphery of the water inlet pipe portion 32 of the centrifugal pump 2 to achieve waterproof sealing. Preferably, the sealing sleeve 7 is made of silicone material.

[0036] See also Figure 3-4The ceramic heating element 4 includes a base tube 41, a ceramic tube 42 sheathed outside the base tube 41, and a lead 43 provided on the ceramic tube 42. A heating circuit 421 is sealed between the ceramic tube 42 and the base tube 41. The heating circuit 421 is connected to an external power source via the lead 43. Preferably, the heating circuit 421 is printed on the inner wall of the ceramic tube 42.

[0037] Therefore, when an external power source supplies power to the heating circuit 421, the heating circuit 421 can generate heat, and the heating circuit 421 transfers heat to the blank tube 41 and the ceramic tube 42, which heat the water inlet pipe portion 32 of the water outlet pipe 3, thereby heating the internal water.

[0038] See also Figure 1-2 The water bottle also includes a sterilization module 8 mounted on the water outlet pipe body 31. The sterilization module 8 comprises multiple UV sterilization components arranged around the outer circumference of the water outlet pipe body 31. Specifically, the UV sterilization components include a light board and a UV lamp mounted on the light board. The portion within the water outlet pipe body 31 is a light-transmitting tube 311. The ultraviolet light emitted by the UV lamp can pass through the light-transmitting tube and irradiate the interior to achieve sterilization and disinfection. Preferably, the light-transmitting tube 311 is made of glass.

[0039] Therefore, when the water in the water outlet pipe 3 is stored for a long time, it is easy to breed bacteria. At this time, even if the water in the inner tank 1 is boiled again, the cooling water remaining in the water outlet pipe 3 will not be boiled, and the ceramic heating body 4 cannot boil this section of residual water. Therefore, the bacteria in this section of residual water cannot be eliminated. If the user drinks this section of residual cooling water, it will have adverse effects on the body. To this end, by setting a sterilization module 8, when water flows through the sterilization module 8, the ultraviolet light emitted by the UV lamp in the sterilization module 8 can pass through the transparent tube 311 to irradiate the interior to achieve sterilization and disinfection, thereby preventing the outflowing water from containing bacteria, thereby protecting the user's health.

[0040] In the embodiment of the present invention, a plurality of UV lamps are provided, and the plurality of UV lamps are spaced apart and arranged on the UV lamp board along the axis direction of the light-transmitting tube 311 .

[0041] To sum up, the utility model provides a kettle with a constant water outlet temperature. A ceramic heating body 4 is sheathed on the outer periphery of the water inlet pipe 32. The ceramic heating body 4 generates heat when energized, and the heat is transferred to the water outlet pipe 3 and heats the water inside it. In addition, an NTC temperature measuring probe 5 is provided on the outer wall of the water inlet pipe 32. When it is detected that the temperature of the water inlet pipe 32 reaches a preset temperature, heating can be stopped. At this time, the temperature of the water in the water outlet pipe 3 is consistent with the temperature of the water in the inner tank 1, so that the temperature of the output water is consistent with the preset temperature, thereby ensuring the brewing quality.

[0042] It should be understood that the terms "top", "bottom", "inside", "outside", 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 modules or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0043] In addition, in the description of the present invention, “a plurality of” and “a plurality of” mean two or more, unless otherwise clearly and specifically defined.

[0044] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
