Example seven:

according to the utility model discloses a second aspect still provides a liquid heating device, include: the seat assembly 100 according to any of the above embodiments; and the electric device is detachably connected with the base 102.

The second aspect of the present invention provides a liquid heating apparatus, which has the overall beneficial effects of the seat assembly 100, due to the seat assembly 100 provided by any of the above embodiments. Wherein, power consumption device and pedestal 102 can dismantle and be connected, and when power consumption device located pedestal 102, power consumption device pressed the touch and press piece 1080 of switch portion 108 into installation cavity 1020, based on power consumption device and pedestal 102 separation, the elastic component 1084 drive touch and press piece 1080 of switch portion 108 stretches out installation cavity 1020.

Further, the electric device comprises a kettle body.

In this embodiment, the electric device includes a kettle body, when the kettle body is placed on the base 102, the kettle body presses the contact element 1080 of the switch unit 108 into the installation cavity 1020, and when the kettle body is separated from the base 102, the elastic element 1084 of the switch unit 108 drives the contact element 1080 to extend out of the installation cavity 1020.

Example eight:

as shown in fig. 1 to 3, according to an embodiment of the present invention, a base assembly 100 is provided, the base assembly 100 includes a first housing 1022, a second housing 1024, a switch unit 108, a power supply unit 106 and a power supply base 104, and through the arrangement of the switch unit 108, the power supply unit 106 and the power supply base 104 can be switched on or off according to whether the kettle body is loaded on the base 102, that is, according to gravity, it is determined whether the kettle body is on the base 102, and when it is determined that the kettle body is not on the base 102, the power supply is automatically cut off, so as to ensure that the power supply base 104 is not powered; when the kettle body is judged to be on the seat body 102, the power supply is switched on, and the power supply base 104 can normally supply power to the kettle body heating system.

Further, the base assembly 100 is connected by external wiring to the copper dome 1040 of the power supply base 104, the copper dome 1040 is always charged, and when the kettle is placed on the base 102, the copper dome 1040 is connected to the heating system of the kettle. As shown in fig. 4, in the present application, after the external circuit enters the housing assembly 100, before the external circuit is connected to the copper dome 1040, a switch portion 108 capable of automatically cutting off the power is added. When the kettle body is placed on the base 102, the kettle body presses down the pressing member 1080 to drive the second connector 1082 downward, and the first connector 1060 contacts the second connector 1082.

Further, the embodiment that this application provided is divided into that switch portion 108 sets up on the live wire connecting wire alone and the switch sets up respectively on live wire connecting wire, zero line connecting wire two kinds. In the case of the solution in which the switch portion 108 is separately disposed on the live line connection line, as shown in fig. 7, only one touch member 1080 is reserved, which has the disadvantage that a child may press the touch member 1080 with one hand and touch the power supply base 104 with the other hand by using a metal rod, resulting in a failure of the protection function. As shown in fig. 6, for the arrangement of the switch portion 108 with the live connection line and the neutral connection line respectively, it is required to design to ensure that half of the maximum compressible amount of the elastic member 1084 is smaller than the distance between the first connecting member 1060 and the second connecting member 1082. According to the scheme, two touch pressing pieces 1080 are required to be pressed down, the first connecting piece 1060 can be contacted with the second connecting piece 1082, after the touch pressing piece 1080 on one side is pressed down singly, the first connecting piece 1060 cannot be contacted with the second connecting piece 1082, and the circuit is still in a power-off state.

Further, as shown in fig. 5, a first limit post 1086 and a second limit post 1088 are respectively disposed at the lower portions of the first housing 1022 and the pressing member 1080 at the installation position of the elastic member 1084, so as to fix the position of the spring and ensure that half of the compression amount of the spring is smaller than the distance between the first connecting member 1060 and the second connecting member 1082.

The embodiment that this application provided, through increasing switch portion 108, realize the kettle body and take off the back, copper shell fragment 1040 on the pedestal 102 is uncharged, has avoided when children remove touching copper shell fragment 1040 with metal article such as iron nail, the electric shock accident that probably causes.
