[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Refer to Figures 1-4 , the present invention provides an electric hot water cup, including a cup body 1, a heater 2 arranged at the bottom of the cup body 1, and a power supply base 3 detachably connected to the heater 2; wherein, the heater 2 includes a heating tube for fitting against the bottom of the cup body 1 to heat the water in the cup body 1, a circuit board 24 electrically connected to the heating tube, a battery 25 electrically connected to the circuit board 24, and an upper coupler 22; the upper coupler 22 is located at the inner bottom of the heater 2; the top of the power supply base 3 is provided with a lower coupler 31, and the side of the power supply base 3 is provided with a mains socket 32 electrically connected to the lower coupler 31, and the mains socket 32 is used to connect to an external mains supply.

[0037] Thus, the heater 2 and the power base 3 can be electrically connected through the coupling connection between the upper coupler 22 and the lower coupler 31. At this time, the commercial power can be used to supply power to the heating tube to heat and boil the water in the cup body 1. When the heater 2 is separated from the power base 3, the battery 25 can be used to supply power to the heating tube to heat and keep warm the water in the cup body 1.

[0038] Therefore, for the electric water cup of the present utility model, by providing a commercial power socket 32 on the power base 3, when the heater 2 at the bottom of the cup body 1 is coupled with the power base 3, the power base 3 can be connected to the external commercial power through the commercial power socket 32 to supply power to the heating tube, thereby realizing heating and boiling of the water in the cup body 1. When the heater 2 at the bottom of the cup body 1 is separated from the power base 3, the commercial power can be disconnected, thus achieving the purpose of safe use. In addition, by providing a battery 25 inside the cup body 1, it can realize heating and keeping warm of the water in the cup body 1, thus facilitating users to carry it out when going out, and having relatively high practicability.

[0039] Furthermore, the heating tube includes a first heating tube 231 and a second heating tube 232. The first heating tube 231 is used to heat and boil the water in the cup body 1, and the second heating tube 232 is used to heat and keep warm the water in the cup body 1. The circuit board 24 is a high-voltage circuit board, and the high-voltage circuit board is electrically connected to the first heating tube 231 and the upper coupler 22 respectively. Among them, a low-voltage circuit board is also provided on the high-voltage circuit board, and the low-voltage circuit board is electrically connected to the second heating tube 232 and the battery 25 respectively.

[0040] Thus, when it is necessary to boil the water in the cup body 1, the heater 2 can be placed on the power base 3 to achieve coupling connection. Then, the power plug electrically connected to the commercial power is inserted into the commercial power socket 32 of the power base 3 to supply power to the first heating tube 231, and the first heating tube 231 is controlled to work through the high-voltage circuit board to heat and boil the water in the cup body 1. When it is necessary to keep warm the water in the cup body 1, at this time, the heater 2 can be separated from the power base 3. The battery 25 in the heater 2 can supply power to the second heating tube 232, and the second heating tube 232 is controlled to work through the low-voltage circuit board to heat and keep warm the water.

[0041] Refer to Figure 4 further, the heater 2 further includes a housing 21. An installation cavity is formed by enclosing between the housing 21 and the bottom of the cup body 1. The heating tube, the circuit board 24, the battery 25, and the upper coupler 22 are all arranged in the installation cavity. Among them, a partition 26 arranged in the installation cavity is also included. The partition 26 divides the installation cavity into a first cavity and a second cavity arranged up and down. The heating tube and the circuit board 24 are both arranged in the first cavity, and the battery 25 and the upper coupler 22 are both arranged in the second cavity.

[0042] Thus, by providing the partition plate 26, the influence of the high temperature generated by the heating tube on the battery 25 can be avoided, thereby ensuring the performance of the battery 25 and extending the service life of the battery 25.

[0043] Furthermore, it also includes a mounting bracket 27 disposed in the first cavity. The upper end surface of the mounting bracket 27 is connected to the bottom of the cup body 1 to tightly fix the heating tube; the lower end surface of the mounting bracket 27 is connected to the partition plate 26 to limit and fix the circuit board 24.

[0044] In addition, it also includes an NTC temperature probe (not shown in the figure) and a display 28 that are electrically connected to the circuit board 24. The NTC temperature probe penetrates through the bottom of the cup body 1 to detect the temperature of the water in the cup body 1, and the display 28 is used to display the water temperature. In addition, a control button 29 is provided below the display 28, and the user can adjust the internal water temperature of the cup body 1 by pressing the control button 29.

[0045] Referring to Figure 4 , the electric water cup further includes a cup lid assembly 4 disposed at the water outlet of the cup body 1. The cup lid assembly 4 includes a cup lid base 41 sleeved on the water outlet of the cup body 1 and a flip cover 42 rotatably disposed on the cup lid base 41. A plurality of steam vent holes 421 are formed in the flip cover 42.

[0046] Thus, after the flip cover 42 is closed, the steam can be discharged by using the plurality of steam vent holes 421 provided on the flip cover 42, thereby avoiding the harm of high-temperature steam to the user. At the same time, the closing of the flip cover 42 can reduce the entry of dust and the like into the cup body 1, and when the flip cover 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.

[0047] Furthermore, a steam valve 43 is also provided on the flip cover 42. A mounting convex ring 422 surrounding the outer peripheral side of the plurality of steam vent holes 421 is provided on the side of the flip cover 42 facing the cup body 1; the steam valve 43 includes a valve body 431 and a fixing sleeve 432. The valve body 431 is disposed within the mounting convex ring 422, and the fixing sleeve 432 is sleeved outside the mounting convex ring 422 and tightly fixes the valve body 431; wherein, an exhaust passage communicating with the plurality of steam vent 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.

[0048] 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 steam vent holes 421 and be discharged.

[0049] In addition, it further includes a sealing sleeve 433 sleeved on the fixed sleeve 432. When the flip cover 42 is closed on the cup lid base 41, the sealing sleeve 433 abuts against the cup lid water outlet on the cup lid base 41 to form a seal, thereby only allowing steam to flow out from the steam valve 43. Further still, it includes a breathable film (not shown in the figure) disposed within the mounting collar 422. The steam valve 43 is connected to the flip cover 42 and fixes the breathable film on a plurality of steam vent holes 421.

[0050] Thus, by utilizing the physical properties of the breathable film, it is possible to guide the steam to flow outwards while preventing the liquid in the cup body 1 from flowing outwards, and also preventing external dust from falling into the cup body 1.

[0051] In summary, an electric hot water cup provided by the present utility model is equipped with a mains socket 32 on the power base 3. When the heater 2 at the bottom of the cup body 1 is coupled and connected to the power base 3, at this time, the power base 3 can be connected to the external mains through the mains socket 32 to supply power to the heating tube, thereby heating and boiling the water in the cup body 1; when the heater 2 at the bottom of the cup body 1 is separated from the power base 3, it can disconnect the mains, thus achieving the purpose of safe use; in addition, by arranging a battery 25 inside the cup body 1, it can heat and keep warm the water in the cup body 1, thus facilitating users to carry it when going out, and having relatively high practicality.
