DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example 1: A safe power supply stand for electric kettle, please refer to Figure 1-Figure 6 , including a power supply seat body 1, a kettle 2, a lower coupler 3, an electric wire 4, a wiring terminal 401 and an upper coupler 13, the kettle 2 is placed on the power supply seat body 1, the lower coupler 3 is fixedly connected to the power supply seat body 1, the rear side of the power supply seat body 1 is connected to the electric wire 4, one end of the electric wire 4 is connected to the wiring terminal 401, the bottom of the kettle 2 is fixedly connected to the upper coupler 13, the inside of the power supply seat body 1 is fixedly connected to a circuit board 5, the circuit board 5 is fixedly connected to a connecting plate 7, the connecting plate 7 is fixedly connected to a first contact block 303, the first contact block 303 is fixedly connected to a contact rod 301, the contact rod 301 and the lower coupler 3 are connected. An elastic member 302 is connected, a fixing plate 9 is fixedly connected to the circuit board 5, a second contact block 8 is arranged on the fixing plate 9, the first contact block 303 can contact the second contact block 8, a sealing gasket 15 is arranged on the power supply seat body 1, the sealing gasket 15 reduces the metal gap between the kettle 2 and the power supply seat body 1, so that the kettle 2 and the sealing gasket 15 are more fitted, a filter screen 16 is embedded in the kettle 2, the filter screen 16 filters the water inside the kettle 2, a wear-resistant sleeve 17 is fixedly connected to the rear side of the power supply seat body 1, one end of the wire 4 is located inside the wear-resistant sleeve 17, the wear-resistant sleeve 17 protects the wire 4, thereby preventing the wire 4 from breaking due to wear.
[0024] When it is necessary to use the safe power supply socket, place the kettle 2 filled with water on the power supply socket body 1 so that the upper coupler 13 and the lower coupler 3 fit together. After the kettle 2 is connected to the power supply socket body 1, it wraps the coupler and has the opportunity to touch the live parts of the power supply socket body 1. Then insert the terminal 401 into the power supply. Due to the action of gravity, the kettle 2 squeezes the contact rod 301 and moves downward, and the elastic member 302 is compressed accordingly, causing the connecting plate 7 to bend downward, thereby causing the first contact block 303 to contact the second contact block 8, thereby forming a passage, thereby heating the water. When the water boils, remove the kettle 2 from the power supply socket body 1. At this time, the elastic member 302 returns to its original state to cause the contact rod 301 to move upward, and the connecting plate 7 returns to its original state to cause the first contact block 303 to move upward and no longer contact the second contact block 8, automatically opening to form a power supply socket passage, so that the entire power supply socket is no longer energized, thereby achieving the purpose of automatic power-off, avoiding the risk of electric shock caused by accidentally touching the live parts, thereby improving safety.
[0025] Example 2: Based on Example 1, please refer to Figure 2 and Figure 3 Two signal modules 6 are provided on the circuit board 5 by means of bolt connection, a plurality of induction blocks 11 are fixedly connected to the power supply seat body 1, and the induction blocks 11 are electrically connected to the signal modules 6, a current gate 10 is provided on the circuit board 5 by means of bolt connection, and a warning light 12 is provided on the power supply seat body 1 by means of bolt connection, and the warning light 12 is electrically connected to the signal module 6.
[0026] When using the power supply socket, the sensor block 11 module contacts the bottom of the kettle 2, senses the temperature of the kettle 2, and then transmits it to the signal module 6. When the water inside the kettle 2 boils, the signal module 6 controls the prompt light 12 to light up, thereby reminding the user to remove the kettle 2 in time.
[0027] See also Figure 6 A fuse 14 is connected between the circuit board 5 and the wire 4 .
[0028] When using the power supply stand to heat water, the current needs to be transmitted to the circuit board 5 through the fuse 14. When the current is too large, the fuse 14 will be melted and broken, cutting off the power supply stand body 1, thereby protecting the power supply stand body 1 and avoiding damage to the entire power supply stand.
