[0037] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0038] 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, 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.

[0039] 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 this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model.

[0040] Referring to Figures 1-7 , this utility model provides an anti-electric shock electric water cup, which includes a cup body 1, a heater 2 arranged at the bottom of the cup body 1, a cup cover assembly 4 arranged at the top of the cup body 1, and a base 3 detachably connected to the bottom of the heater 2; 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 mains socket 241 arranged on and electrically connected to the circuit board 24, and an upper coupler 23; the base 3 is internally provided with a battery 35 and a control circuit board 36 electrically connected to the battery 35, and a lower coupler 34 electrically connected to the control circuit board 36 is arranged at the top of the base 3;

[0041] Wherein, it further includes a protection component 25, and the protection component 25 includes a contact switch arranged on the circuit board 24 and electrically connected to the upper coupler 23, a moving bracket 251 cooperating with the contact switch, and an elastic member 252 cooperating with the moving bracket 251; a positioning convex block 33 cooperating with the moving bracket 251 is arranged on the base 3;

[0042] Thus, when the base 3 is separated from the heater 2, under the elastic force of the elastic member 252, the moving bracket 251 resets and does not trigger the contact switch. At this time, the upper coupler 23 and the circuit board 24 are in a disconnected state. At this time, if the mains socket 241 is connected to the external mains and the user accidentally touches the upper coupler 23, it will not cause electric shock, thus ensuring the use safety of the product; when the base 3 is connected to the heater 2, the upper coupler 23 and the lower coupler 34 are coupled to achieve electrical conduction, and the positioning convex block 33 on the base 3 abuts against the moving bracket 251 and drives the moving bracket 251 to move to trigger the contact switch. At this time, the upper coupler 23 and the circuit board 24 are in a conducting state, so that power supply can be realized through the battery 35, ensuring the normal use of the product.

[0043] Preferably, the contact switch is a microswitch 242. The microswitch 242 is provided with a contact point 2422 and a spring piece 2421. The moving bracket 251 abuts and cooperates with the spring piece 2421 and controls the movement of the spring piece 2421 to realize its contact with or separation from the contact point 2422, thereby realizing the connection or disconnection between the circuit board 24 and the upper coupler 23.

[0044] Of course, it should be noted that in other embodiments, a non-contact switch, such as a photoelectric switch, may also be provided. As long as the photoelectric switch is triggered, the circuit between the circuit board 24 and the upper coupler 23 can be connected, which can also achieve the same technical effect and is not limited here.

[0045] In this embodiment, the upper coupler 23 includes a first conductive pin that passes through the bottom of the heater 2 and is flush with the bottom surface of the heater, and the lower coupler 34 is a second conductive pin that passes through the top of the base 3. When the first conductive pin and the second conductive pin collide with each other, electrical conduction can be achieved.

[0046] See also Figure 6 Furthermore, the heater 2 includes a housing 21, the inner bottom of which is provided with two mounting bosses 213, the movable bracket 251 is sleeved on the mounting bosses 213 and can move up and down along the axis direction of the mounting bosses 213; wherein, it also includes a positioning screw 253 connected to one mounting boss 213, a limiting gasket 254 is provided between the positioning screw 253 and the mounting boss 213; the elastic member 252 is a return spring, which is sleeved on the mounting boss 213 and one end of which abuts against the limiting gasket 254, and the other end of which abuts against the movable bracket 251. In addition, a through slot 211 communicating with the movable bracket 251 is also provided at the bottom of the housing 21.

[0047] Thus, when the base 3 is connected to the heater 2, the positioning protrusion 33 on the base 3 extends into the through slot 211 and abuts against the movable bracket 251, and drives the movable bracket 251 to overcome the elastic force of the reset spring and move, thereby driving the spring sheet 2421 to rotate and contact the contact 2422, thereby realizing the circuit conduction between the upper coupler 23 and the circuit board 24. Conversely, when the base 3 is separated from the heater 2, the movable bracket 251 moves and resets under the action of the reset spring, and the spring sheet 2421 resets and separates from the contact 2422, thereby disconnecting the circuit between the upper coupler 23 and the circuit board 24.

[0048] See also Figures 4-5 , and also includes a mounting bracket 26 disposed in the housing 21, the upper end surface of the mounting bracket 26 is connected to the bottom of the cup body 1 to press and fix the heating tube; the lower end surface of the mounting bracket 26 is connected to the housing 21 to limit and fix the circuit board 24. The heating tube includes a first heating tube 271 and a second heating tube 272, the first heating tube 271 is used to heat and boil the water in the cup body 1, and the second heating tube 272 is used to heat and keep the water in the cup body 1 warm; the circuit board 24 is a high-voltage circuit board and the first heating tube 271 is electrically connected to the high-voltage circuit board; 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 272 and the upper coupler 23 respectively.

[0049] Thus, when it is necessary to boil the water in the cup body 1, the power plug electrically connected to the mains can be inserted into the mains socket 241 to supply power to the first heating tube 271, and the first heating tube 271 can be controlled by the strong power circuit board to work to heat and boil the water in the cup body 1. When it is necessary to keep the water in the cup body 1 warm, since the lower coupler 34 on the base 3 is coupled with the upper coupler 23 on the heater 2 to achieve electrical conduction, the battery 35 in the base 3 can supply power to the second heating tube 272, and the second heating tube 272 can be controlled by the weak power circuit board to work to heat and keep the water warm.

[0050] Furthermore, it further includes a protective cover 22. A through hole communicating with the mains socket 241 is formed in the side of the outer shell 21, and the protective cover 22 is rotatably arranged at the through hole to open or seal the mains socket 241.

[0051] Thus, by providing the protective cover 22, the mains socket 241 can be protected to prevent external pollutants from entering the mains socket 241, thereby ensuring the normal use of the product. In addition, setting the protective cover 22 can also prevent users from accidentally touching the mains socket 241 and causing electric shock, thus ensuring the use safety of users.

[0052] Refer to Figure 1 and Figure 7 , the base 3 includes a base body 31 and an upper cover 32 covering the top of the base body 31. The base body 31 is connected to the upper cover 32 and a cavity is formed inside. The battery 35 and the control circuit board 36 are both arranged in the cavity. The positioning convex block 33 is integrally formed on the upper cover 32. The lower coupler 34 partially penetrates through the upper cover 32 and is arranged.

[0053] Refer to Figures 2-3 furthermore, a clamping block 321 is provided on the upper cover 32, and a clamping groove 212 is formed in the outer periphery of the bottom of the outer shell 21. The clamping block 321 is detachably screwed and assembled into the clamping groove 212. Specifically, the clamping groove 212 includes a guiding sliding groove 2122 and a positioning groove 2121. The guiding sliding groove 2122 extends along the circumferential direction. The positioning groove 2121 is located at the head end of the guiding sliding groove 2122 and communicates with the guiding sliding groove 2122. Among them, a concave position 3211 is provided on the clamping block 321, and a convex point 2123 is provided in the guiding sliding groove 2122. When the clamping block 321 is clamped into the positioning groove 2121 and rotated, the clamping block 321 can slide along the guiding sliding groove 2122 until the concave position 3211 is clamped with the convex point 2123. At this time, the base 3 is fixedly connected to the heater 2.

[0054] In summary, for the anti-electric shock electric water cup provided by the present utility model, by providing a protection component 25, when the base 3 is separated from the heater 2, under the action of the elastic member 252, the moving bracket 251 resets and does not trigger the contact switch. At this time, the upper coupler 23 and the circuit board 24 are in a disconnected state. At this time, if the mains socket 241 is connected to the external mains power and the user accidentally touches the upper coupler 23, no electric shock will occur, thus ensuring the safety of product use. In addition, when the base 3 is connected to the heater 2, it can drive the moving bracket 251 to move to trigger the contact switch. At this time, the upper coupler 23 and the circuit board 24 are in a conducting state, and at the same time, the upper coupler 23 and the lower coupler 34 are coupled and electrically conducted, so that power supply can be realized through the battery 35, ensuring the normal use of the product.

[0055] It should be noted that when an element is referred to as being "fixed to" or "disposed 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.

[0056] 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 cannot be understood as a limitation to the present utility model.
