[0034] 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.

[0035] In the description of the present invention, 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, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the module or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0036] 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 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.

[0037] Refer to Figures 1-7 , the present invention provides an electrically heated water cup with safe use, including a cup body 1, a cup cover assembly 3 arranged on the top of the cup body 1, and a heater 2 arranged on the bottom of the cup body 1; wherein, a water cavity is arranged inside the cup body 1; the heater 2 includes a heating tube for fitting on the bottom of the cup body 1 to heat the liquid in the water cavity, a circuit board 24 electrically connected to the heating tube, a mains socket 241 arranged on the circuit board 24, and a conductive socket 22. In addition, a safety protection component 28 is arranged inside the heater 2, and the safety protection component 28 includes a safety bracket 281 at least partially extending into the mains socket 241, a baffle 2811 arranged on the safety bracket 281, and an elastic member in abutting cooperation with the safety bracket 281.

[0038] Therefore, when the power plug is inserted into the AC power socket 241, it can drive the safety bracket 281 to overcome the elastic force of the elastic member and move, thereby driving the baffle 2811 to move and cover the conductive socket 22; when the power plug is unplugged, the safety bracket 281 can be reset under the elastic force of the elastic member, thereby driving the baffle 2811 to reset and open the conductive socket 22.

[0039] Therefore, the electric water cup of the utility model, by setting a safety protection component 28 in the heater 2, when the power plug is inserted into the AC power socket 241, the power plug can interfere with the safety bracket 281 and drive the safety bracket 281 to move, thereby driving the baffle 2811 to move to shield the conductive socket 22, thereby preventing the user from accidentally touching the conductive socket 22 and causing electric shock, thereby ensuring the safety of the product and making the product meet safety regulations.

[0040] In this embodiment, the safety bracket 281 and the baffle are integrally formed.

[0041] See also Figures 1-4 The heater 2 also includes an outer shell 21, which includes a cylindrical shell 211 and a bottom cover 212 covered at the bottom of the shell 211. The bottom of the cup body 1, the shell 211 and the bottom cover 212 form an installation cavity, and the heating tube, the circuit board 24 and the safety protection component 28 are all arranged in the installation cavity.

[0042] In this embodiment, a waterproof silicone ring 29 is disposed between the housing 211 and the bottom cover 212 to form a waterproof seal.

[0043] Furthermore, the safety protection component 28 also includes a pressure plate 282, which is connected to the bottom cover 212 to limit and fix the safety bracket 281; wherein, the safety bracket 281 is partially penetrated by the pressure plate 282, so that the pressure plate 282 can guide the movement of the safety bracket 281.

[0044] In this embodiment, the elastic member is a return spring 283 , which is disposed in the safety bracket 281 and has one end abutting against the safety bracket 281 and the other end abutting against the bottom cover 212 .

[0045] Furthermore, in order to solve the problem that the electric water cup in the prior art shakes during use, thereby causing the heating tube or circuit board 24 in the heater 2 to deviate and cause failure, etc. To this end, the present application also sets a mounting bracket 27 in the mounting cavity, and the top of the mounting bracket 27 is connected to the bottom of the cup body 1 by bolts to press and fix the heating tube, and the bottom surface of the mounting bracket 27 is connected to the bottom cover 212 by bolts to press and fix the circuit board 24.

[0046] Thus, by providing the mounting bracket 27, the fixing of the heating tube and the circuit board 24 can be achieved, thereby avoiding the risk of component failure caused by the shaking of the electric water cup.

[0047] Furthermore, the electric water cup further includes a protective cover 25. A through hole communicating with the mains socket 241 is formed on the housing 211. The protective cover 25 is rotatably provided at the through hole to open or seal the mains socket 241; preferably, the protective cover 25 is made of silica gel material.

[0048] Thus, by providing the protective cover 25, the mains socket 241 can be protected to prevent external contaminants from entering the mains socket 241, thereby ensuring the normal use of the product; in addition, providing the protective cover 25 can also prevent users from accidentally touching the mains socket 241 and getting an electric shock, thus ensuring the user's safety in use.

[0049] Refer to Figures 1-4 again, the heating tube includes a first heating tube 261 and a second heating tube 262. The first heating tube 261 is used to heat and boil the liquid in the water chamber, and the second heating tube 262 is used to heat and keep warm the liquid in the water chamber; the circuit board 24 is a high-voltage circuit board and the first heating tube 261 is electrically connected to the high-voltage circuit board; in addition, 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 262 and the conductive socket 22 respectively.

[0050] Refer to Figures 5-7 again, the heater 2 further includes a base 4. The base 4 is detachably connected to the heater 2; specifically, the base 4 includes a base body 42 and an upper cover 41 covering the base body 42 and forming a cavity inside. A battery 46 and a control circuit board 47 electrically connected to the battery 46 are provided inside the cavity. The upper cover 41 is provided with a conductive plug 43 electrically connected to the control circuit board 47. Thus, when the base 4 is connected to the heater 2, the conductive plug 43 is inserted into the conductive socket 22 to achieve electrical conduction.

[0051] Thus, when it is necessary to boil the liquid in the cup body 1, first separate the base 4 from the heater 2, then insert the power plug electrically connected to the mains into the mains socket 241 to supply power to the first heating tube 261, and control the first heating tube 261 to work through the high-voltage circuit board to heat and boil the liquid in the water chamber; when it is necessary to keep warm the liquid in the cup body 1, at this time, it is necessary to connect the base 4 to the heater 2. At this time, the conductive plug 43 on the base 4 is inserted into the conductive socket 22 of the heater 2 to achieve electrical conduction, so that the battery 46 in the base 4 can supply power to the second heating tube 262, and control the second heating tube 262 to work through the low-voltage circuit board to heat and keep warm the liquid in the water chamber.

[0052] Furthermore, 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 circuit board 24. In addition, it further includes a display screen 23 electrically connected to the circuit board 24. After the NTC temperature probe 263 sends the acquired water temperature signal to the circuit board 24, the water temperature is displayed through the display screen 23 for the user to obtain the water temperature data inside the cup body 1 in real time.

[0053] Furthermore, a positioning bump 45 is provided on the top of the base 4, and a corresponding positioning groove 2122 is provided at the bottom of the bottom cover 212; thus, when the base 4 is connected to the heater 2, the quick assembly of the two can be realized through the snap-fit of the positioning bump 45 and the positioning groove 2122, as well as the insertion fit of the conductive socket 22 and the conductive plug 43.

[0054] In addition, it further includes a locking sleeve 44 rotatably sleeved outside the base 4. An internal thread 441 is provided on the inner side wall of the locking sleeve 44, and an external thread 2121 matching the internal thread 441 is provided on the outer side wall of the bottom cover 212; thus, the detachable connection between the base 4 and the heater 2 can be realized through the threaded connection and cooperation between the locking sleeve 44 and the bottom cover 212.

[0055] In summary, for an electric water cup with safe use provided by the present utility model, by providing a safety protection component 28, when the power plug is inserted into the mains socket 241, it can drive the safety bracket 281 to move and then drive the baffle 2811 to move to shield the conductive socket 22, thereby avoiding the user accidentally touching the conductive socket 22 and causing electric shock, thus ensuring the safe use of the product and further enabling the product to meet the safety regulations requirements.
