[0038] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0039] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the referred module or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0041] Refer to Figures 1-10 , the present utility model provides a battery base detachable electric water cup, which includes a cup body 1 made of stainless steel material, a heater 2 arranged at the bottom of the cup body 1 to heat the liquid in the cup body 1, and a battery base 3 detachably connected to the bottom of the heater 2. Among them, a water cavity is provided inside the cup body 1; the heater 2 includes a first heating tube 261 for fitting on the bottom of the cup body 1 to heat and boil the liquid in the water cavity, a second heating tube 262 for fitting on the bottom of the cup body 1 to heat and keep warm the liquid in the water cavity, a strong power circuit board 24 electrically connected to the first heating tube 261, and a weak power circuit board arranged on the strong power circuit board 24 and electrically connected to the second heating tube 262; a mains interface 241 is provided on the strong power circuit board 24, and an upper coupler 22 is electrically connected to the weak power circuit board; the battery base 3 includes a base body 32 and an upper cover 31 covering the top of the base body 32. The base body 32 is connected to the upper cover 31 and a cavity is formed inside. The cavity is provided with a power supply battery 36 and a control circuit board 37 electrically connected to the power supply battery 36. A lower coupler 33 electrically connected to the control circuit board is provided on the upper cover 31. Thus, when the battery base 3 is connected to the heater 2, the upper coupler 22 and the lower coupler 33 are coupled and connected to achieve electrical conduction.

[0042] Thus, when it is necessary to boil the liquid in the cup body 1, first separate the battery base 3 from the heater 2, then insert the power plug electrically connected to the mains into the mains interface 241 to supply power to the first heating tube 261, and control the first heating tube 261 to work through the strong power circuit board 24 to heat and boil the liquid in the water cavity; when it is necessary to keep warm the liquid in the cup body 1, at this time, it is necessary to connect the battery base 3 to the heater 2. At this time, the upper coupler 22 and the lower coupler 33 are coupled and connected. The power supply battery 36 can supply power to the second heating tube 262, and control the second heating tube 262 to work through the weak power circuit board to heat and keep warm the liquid in the water cavity.

[0043] Therefore, in the present application, by detachably connecting the battery base 3 to the heater 2, when it is necessary to connect to the mains power supply to heat and boil the liquid in the cup body 1, the battery base 3 can be separated from the heater 2 at this time, so as to avoid the influence of the heat generated by the first heating tube 261 on the power supply battery 36; when it is necessary to heat and keep warm the liquid in the cup body 1, although the battery base 3 is connected to the heater 2 at this time, since the heat generated by the second heating tube 262 is relatively low, and the power supply battery 36 is arranged in the battery base 3 rather than in the heater 2, the power supply battery 36 is also less affected by the second heating tube 262. Therefore, the power supply battery 36 of the present application can be stored and operated at a relatively low temperature, which can not only ensure the performance of the power supply battery 36, but also maximize its service life.

[0044] Refer to Figure 5 , further, the heater 2 further includes an NTC temperature probe 263 that penetrates through the bottom of the cup body 1 to detect the temperature of the liquid in the water cavity, and the NTC temperature probe 263 is electrically connected to the high-voltage circuit board 24. In addition, a display screen 23 electrically connected to the high-voltage circuit board 24 is further included. After the NTC temperature probe 263 sends the obtained water temperature signal to the high-voltage circuit board 24, the water temperature is displayed through the display screen 23 to obtain the water temperature data inside the cup body 1 in real time.

[0045] Even further, the heater 2 further includes a mounting bracket 27. One side of the mounting bracket 27 is connected to the bottom of the cup body 1 to press and fix the first heating tube 261 and the second heating tube 262; the other side of the mounting bracket 27 is used to mount the high-voltage circuit board 24. Among them, the heater further includes a housing 21, and the housing 21 includes a cylindrical shell 211 and a bottom cover 212 covering the bottom of the shell 211. The other side of the mounting bracket 27 is connected to the bottom cover 212 to press and fix the high-voltage circuit board 24.

[0046] In this embodiment, a waterproof silicone ring 29 is further included between the shell 211 and the bottom cover 212 to form a waterproof seal.

[0047] Refer to again Figures 5-6, To further improve the safety of using the electric water cup, a safety protection component 28 is also provided inside the heater 2. The safety protection component 28 includes a safety bracket 281 partially extending into the mains interface 241 and a return spring 283 in abutting cooperation with the safety bracket 281. The return spring 283 is in abutting cooperation with the safety bracket 281 and the bottom cover 212 respectively. Thus, when the power plug is inserted into the mains interface 241, it can drive the safety bracket 281 to overcome the elastic force of the return spring 283 and move to shield the opening of the upper coupler 22; when the power plug is pulled out, at this time, the safety bracket 281 can be reset under the elastic force of the return spring 283 to open the upper coupler 22.

[0048] Furthermore, the safety protection component 28 further includes a pressing plate 282, and the safety bracket 281 is partially inserted through the pressing plate 282; the pressing plate 282 is connected to the bottom cover 212 to limit and fix the safety bracket 281; the pressing plate 282 is used to guide the movement of the safety bracket 281.

[0049] Thus, by providing the safety protection component 28, when the power plug is inserted, it can prevent users from touching the pins inside the upper coupler 22 and causing electric shock, thereby meeting the safety regulations requirements and ensuring the safety of users during use.

[0050] In addition, a protective cover 25 is further included. A through hole communicating with the mains interface 241 is provided on the housing 211. The protective cover 25 is rotatably arranged at the through hole to open or seal the mains interface 241, thereby further enhancing the safety of users during use and also preventing external pollutants from entering the mains interface 241 and causing pollution.

[0051] Furthermore, a positioning bump 35 is further provided at the top of the battery base 3, and a corresponding positioning groove 2122 is provided at the bottom of the bottom cover 212; thus, when the battery base 3 is connected to the heater 2, the quick assembly of the two can be achieved through the snap-fit of the positioning bump 35 and the positioning groove 2122 and the plug-in fit of the upper coupler 22 and the lower coupler 33.

[0052] In addition, a locking sleeve 34 rotatably sleeved outside the battery base 3 is further included. An internal thread 341 is provided on the inner side wall of the locking sleeve 34 in a circumferential manner, and an external thread 2121 matching the internal thread 341 is provided on the outer side wall of the bottom cover 212 in a circumferential manner; thus, the detachable connection between the battery base 3 and the heater 2 can be achieved through the threaded connection and cooperation between the locking sleeve 34 and the bottom cover 212.

[0053] Refer to again Figures 8-10, the electric water cup further includes a cup lid assembly 4 provided at the water outlet of the cup body 1. The cup lid assembly 4 includes a cup lid base 41 sleeved at the water outlet of the cup body 1 and a flip lid 42 rotatably provided on the cup lid base 41. A plurality of ventilation holes 421 are formed in the flip lid 42.

[0054] Thus, when the flip lid 42 is closed, the steam can be discharged by using the plurality of ventilation holes 421 provided in the flip lid 42, thereby avoiding the harm of high-temperature steam to the user. At the same time, the closing of the flip lid 42 can reduce the entry of dust and the like into the cup body 1, and when the flip lid 42 is opened, it is convenient for the liquid in the cup body 1 to flow out through the water outlet for the user to drink.

[0055] Furthermore, a steam valve 43 is also provided on the flip lid 42. On the side of the flip lid 42 facing the cup body 1, there is a mounting convex ring 422 surrounding the outer peripheral side of the plurality of ventilation holes 421. The steam valve 43 includes a valve body 431 and a fixing sleeve 432. The valve body 431 is arranged within the mounting convex ring 422, and the fixing sleeve 432 is sleeved outside the mounting convex ring 422 and presses and fixes the valve body 431. Among them, an exhaust passage communicating with the plurality of ventilation holes 421 is formed inside the valve body 431, and a plurality of steam inlet holes 4321 communicating with the exhaust passage are formed at the bottom of the fixing sleeve 432.

[0056] Thus, the water vapor generated inside the cup body 1 can sequentially pass through the plurality of steam inlet holes 4321, the exhaust passage, and the plurality of ventilation holes 421 and be discharged.

[0057] In addition, a sealing sleeve 433 is also sleeved on the fixing sleeve 432. When the flip lid 42 is closed on the cup lid base 41, the sealing sleeve 433 abuts against the cup lid water outlet 411 on the cup lid base 41 to form a seal, so that only steam can flow out from the steam valve 43. Furthermore, a ventilation film (not shown in the figure) is also provided within the mounting convex ring 422. The steam valve 43 is connected to the flip lid 42 and fixes the ventilation film on the plurality of ventilation holes 421.

[0058] Thus, by utilizing the physical properties of the ventilation film, it is possible to guide the steam to flow outwards while preventing the liquid in the cup body 1 from flowing outwards and preventing external dust from falling into the cup body 1.

[0059] In summary, for the detachable electric water cup with a battery base provided by the present utility model, the power supply battery 36 is arranged in the battery base 3 and the battery base 3 is detachably connected to the heater 2. With this arrangement, when it is necessary to connect to the external mains power to heat and boil the liquid in the cup body 1, the battery base 3 can be separated from the heater 2 at this time, so as to avoid the influence of the heat generated by the first heating tube 261 on the power supply battery 36. When it is necessary to heat and keep warm the liquid in the cup body 1, although the battery base 3 is connected to the heater 2 at this time, since the heat generated by the second heating tube 262 is relatively low, and the power supply battery 36 is arranged in the battery base 3 rather than in the heater 2, the power supply battery 36 is also less affected by the second heating tube 262. Therefore, the power supply battery 36 of the present application can be stored and operated at a relatively low temperature, which can not only ensure the performance of the power supply battery, but also maximize its service life.

[0060] It should be noted that when an element is referred to as being "fixed to" or "arranged on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0061] It should be understood that the orientation or positional relationship indicated by terms such as "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the referred module or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0062] In addition, in the description of the present utility model, the meaning of "a plurality of" or "several" is two or more, unless otherwise specifically defined.
