As shown in fig. 20 and 21, which are related views of the tip cone telescoping assembly 210, the tip cone telescoping assembly 210 further includes a tip cone retainer 2101, a ball 2102, a guide cone 2103, a conductive cone 2104, a return spring 2105, a first conductive block 2106, a second conductive block 2107, a tip cone base 2108, and a tip cone retainer bore 2109. The tip cone retainer ring 2101 is a hollow shape with an open lower end and a closed upper end, and a tip cone retainer ring hole 2109 is formed at the upper end of the tip cone retainer ring 2101 to facilitate the passage of the pintle 101. The tip cone retainer 2101 is provided with a through hole on the side to place the ball 2102, the guide cone 2103 and the conductive cone 2104 are coupled together and move simultaneously, and the guide cone 2103 has a protrusion to catch the ball 2102. The top cone bottom plate 2108 is provided with a first conductive block 2106 and a second conductive block 2107 (the first conductive block 2106 and the second conductive block 2107 can not contact), the first conductive block 2106 is communicated with the conductive wire (namely communicated with the mains supply), when the conductive cone 2104 contacts the first conductive block 2106 and the second conductive block 2107 downwards, the second conductive block 2107 is communicated (the second conductive block 2107 is connected with the live wire extension piece 2071 by an electric wire), one end of the return spring 2105 is fixed on the top cone bottom plate 2108, and the other end of the return spring 2105 is fixed on the conductive cone 2104 and is in a compressed state under a normal state.

The working principle is as follows:

when the kettle body plug 100 is plugged into the power base 300, the pintle 101 on the kettle body plug 100 enters the tip cone expansion assembly 210 through the tip cone fixing ring hole 2109 (the pintle 101 is longer than the limiting ring 107 on the kettle body plug 100 so as to press the tip cone expansion assembly 210 in advance), because the ball 2102 on the tip cone expansion assembly 210 is positioned inside the through hole of the tip cone fixing ring 2101 under normal conditions, the return spring 2105 is in a locked static state under upward elastic pressure, when the guide cone 2103 is pressed downwards by the pintle 101, the ball 2102 can only move left and right but cannot fall down (namely the ball 2102 loosens, the fixing groove is a safety door 2102 for facilitating the safety door 209), because the ball 2102 locks the safety door 209 under the original condition, when the ball 2102 is pressed inwards, the safety door 209 is also just pressed by the kettle body outer ring 104 and the kettle body inner ring 102, so that the safety door 209 can fall downwards, meanwhile, the guiding cone 2103 and the conductive cone 2104 descend so that the conductive cone 210 conducts the first conductive block 2106 and the second conductive block 2107 (the first conductive block 2106 is always connected with the mains supply and is always in a powered state), and the second conductive block 2107 is connected with the fire coil piece 207 through a lead (not shown in the figure), so that the fire coil piece 207 is in a powered state.

As the kettle body plug 100 descends, the live wire contact piece 103 is also descended to contact the live wire coil piece 207, so that the 103 positive contact piece is conductive and the water boiling state is started.

Of course, while the positive contact piece 103 is in contact with the hot coil piece 207, the ground contact piece 105 and the ground contact piece 205 (middle) are also coupled, and the neutral contact pieces 204 and 106 (outermost) are also in contact, thereby forming a complete circuit to complete the water boiling operation.

When the 100 kettle body plug is pulled out from the 200 power supply connector, the safety door spring 208 can rebound the safety door 209, and the return spring 2105 can rebound the conductive cone 2104, so that the original state can be restored, and the ball 2102 can be locked on the right.
