Description

Electric kettle capable of preventing water dripping and short circuit

Technical Field

The invention belongs to the technical field of electric appliances, and particularly relates to an electric kettle.

Background

The electric kettle has the functions of intelligent steam induction control, overheat protection, automatic water boiling power off, dry burning prevention power off and the like, is deeply loved by consumers and is a household appliance widely used at present. The electric heating kettle generally adopts the design of separating a kettle body and a power supply chassis, a heating element is hidden in the kettle body, the power supply chassis is used for being butted with a power supply plug of the kettle body to provide electric energy for the heating element, and the power supply plug of the kettle body is inserted into a power supply interface of a socket when the electric heating kettle is used. The power interface of the current power chassis is a circular recess with an upward opening arranged at the center, and two protruding power terminals are arranged at the center of the recess and are directly connected with a power line. When the electric kettle is used, a user generally cannot take the power line of the base off the socket immediately after boiling water for convenience, so that water drops in the kettle body can be inadvertently dropped into the concave part, and a short circuit between the two power terminals can be caused.

Disclosure of Invention

The invention aims to provide an electric kettle capable of preventing water dripping and short circuit, which can avoid the short circuit of a power supply caused by the fact that dripping water enters a power supply interface of a base.

The electric kettle capable of preventing water dripping and short circuit comprises a kettle body and a base; the top of the base and the bottom of the kettle body are provided with power interfaces which are matched with each other; the key point is that a magnet is arranged at the bottom of the kettle body, a hollow cavity is arranged in the base, a Hall switch corresponding to the position of the magnet is arranged in the hollow cavity, and a power supply interface of the base is connected with a power line through the Hall switch.

The Hall switch is one of proximity switches, can detect the change of a magnetic field, so as to cut off or conduct a circuit between the power line and the power interface, when the kettle body is placed on the base, the Hall switch detects the magnet at the bottom of the kettle body, so as to conduct the power line and the power interface, and the base can provide power for the kettle body through the power interface; when the kettle body is taken away from the base, the Hall switch cannot detect the magnet at the bottom of the kettle body, so that the power line is disconnected with the power interface, and the power interface on the base is uncharged, so that short-circuit accidents cannot be caused even if water drops in the kettle body drop at the power interface of the base carelessly, and a user has sufficient time to treat the water drops at the power interface cleanly and then use the water drops. For safety, two hall switches may be simultaneously provided to connect the zero line, the live line, and the corresponding power terminals, respectively, or only one hall switch may be provided to connect the live line and the corresponding power terminals.

Furthermore, the magnet is embedded in the kettle body, so that the kettle is attractive in appearance, and the magnet can be prevented from being damaged in collision in daily use.

Furthermore, the power interface of the base is positioned at one side of the base, the Hall switch is positioned at the center of the base, and the magnet is positioned at the center of the kettle body. The magnet and the Hall switch are arranged at the central position, so that the Hall switch can detect the magnet no matter how the kettle body rotates relative to the base, and the function of preventing short circuit is normal. In addition, the power interface is arranged at the side part of the base, so that a user can observe the power interface conveniently, and the power interface of the kettle body can be accurately butted with the power interface of the base.

The anti-drip short-circuit electric kettle is provided with the Hall switch capable of detecting the position of the kettle body, and the connection between the power line and the power interface can be automatically cut off after the kettle body leaves the base, so that even if water enters the power interface of the base, a short-circuit accident cannot be caused, and the safety is improved.

Detailed Description

The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.

Example 1:

the embodiment provides an electric kettle capable of preventing water dripping and short circuit, which can avoid the phenomenon that water drips into a power interface of a base to cause power short circuit.

As shown in fig. 1 to 3, the electric kettle for preventing water dripping and short circuit in the embodiment comprises a kettle body 1 and a base 2, wherein a handle 3 is arranged on one side of the kettle body 1, a water outlet 4 is arranged on the other side of the kettle body, a first power supply interface 5 is arranged at the bottom of the handle 3 on one side of the kettle body 1, and a second power supply interface 6 matched with the first power supply interface 5 is arranged on one side of the top of the base 2; a magnet 7 (specifically, a permanent magnet) is embedded in the central position of the bottom of the kettle body 1, a hollow cavity is arranged inside the base 2, a hall switch 8 corresponding to the magnet 7 is arranged in the hollow cavity (namely, the hall switch 8 is located in the central position of the base 2), and the second power interface 6 of the base 2 is connected with a power line 9 through the hall switch 8. In this embodiment, only one hall switch 8 is provided to connect the live wire and the corresponding power supply terminal, and for safety, two hall switches 8 may be provided simultaneously to connect the neutral wire, the live wire, and the corresponding power supply terminals, respectively.

When the kettle body 1 is placed on the base 2, the Hall switch 8 detects the magnet 7 at the bottom of the kettle body 1, so that the power line 9 is conducted with the power interface, and the base 2 can provide power for the kettle body 1 through the second power interface 6; when the kettle body 1 is taken away from the base 2, the Hall switch 8 cannot detect the magnet 7 at the bottom of the kettle body 1, so that the power line 9 is disconnected from the second power supply interface 6, and the second power supply interface 6 on the base 2 is uncharged at the moment, so that even if water drops in the kettle body 1 drop on the second power supply interface 6 of the base 2 carelessly, a short-circuit accident cannot be caused, and a user has sufficient time to treat the water drops at the second power supply interface 6 cleanly and then use the water drops. The handle 3 and the first power interface 5 are positioned at the same side of the kettle body 1, so that when water is poured, the water flowing out of the kettle body 1 along the water outlet 4 cannot enter the first power interface 5, and the safety is better.

The invention has been described in connection with the accompanying drawings, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description, as long as the invention is capable of being practiced without modification in any way whatsoever, and is capable of other applications without departing from the spirit and scope of the invention as defined by the appended claims.
