Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example one
As shown in fig. 1, 2, 3 and 4, the embodiment of the present invention discloses a health preserving pot using a four-ring connector. The health preserving kettle adopts a non-isolated switch power supply, and a 5V direct current power supply is directly and electrically connected with a 220V alternating current zero line.
Specifically, the health preserving kettle includes: the electric kettle comprises a kettle body 10 and a base 20 which are in conductive connection through a four-ring connector 30, wherein a live wire, a zero wire and a ground wire of a 220V power supply are introduced into the base 20 through an electric switch, and are in electric conduction with a live wire connecting pole, a zero wire connecting pole and a kettle body shell of a heating disc 101 at the bottom of the kettle body 10 through three middle poles of the four-ring connector 30.
One pole of a thermistor NTC102 arranged in the kettle body 10 is electrically connected with a controller 201 arranged in the base 20 through the last pole of the four-ring connector 30; the other pole of the thermistor NTC102 is electrically connected to the neutral wire terminal of the heating plate 101, so that a 5V dc power supply can be connected.
The base 20 is provided with a control switch 202, the control switch 202 is arranged on a 220V alternating current live wire in the base 20, and the controller 201 is electrically connected with and controls the on-off of the control switch 202.
It should be noted that the conventional five-ring connector provides five electrical conduction paths: a live line path L, a neutral line path N, a ground path PE, a thermistor first end path D1 and a thermistor second end path D2. In the present embodiment, the lead of the thermistor first end path D1 is electrically connected to the neutral wire, so that the two can share one path in the four-ring connector 30, so that the neutral wire path in the four-ring connector 30 becomes a composite path N-D1 of the neutral wire path N and the thermistor first end path D1. Thus, in this embodiment, the electrical conduction path formed by the four-ring connector 30 is: a live line path L, a zero line path N, a ground path PE and a composite path N-D1.
Moreover, because the control switch 222 is disposed on the 220V ac live wire in the base, and the 5V dc power supply is directly electrically connected to the 220V ac neutral wire, no matter the control switch 202 is turned on to heat the heating plate 101 or the control switch 202 is turned off to stop heating the heating plate 101, the thermistor NTC 212 is turned on to receive the 5V dc power, thereby realizing the temperature monitoring function.
Example two
As shown in fig. 5, 6 and 7, the second embodiment of the present invention discloses a health preserving pot using a four-ring connector.
The health preserving kettle using the four-ring connector provided by the second embodiment is basically the same as the health preserving kettle using the four-ring connector provided by the first embodiment, and the main difference is that: the health preserving kettle adopts a non-isolated switching power supply, and a 5V direct current power supply is directly and electrically connected with a 220V alternating current live wire.
One pole of a thermistor NTC 212 arranged in the kettle body is electrically connected with a controller 221 arranged in the base through the last pole of the four-ring connector; the other pole of the thermistor NTC 212 is electrically connected to the neutral wire terminal of the heating plate 211, so that a 5V dc power supply can be connected.
A control switch 222 is arranged in the base, the control switch 222 is arranged on a 220V alternating current zero line in the base, and the controller 221 is electrically connected with and controls the on-off of the control switch 222.
It should be noted that the conventional five-ring connector provides five electrical conduction paths: the circuit comprises a live wire passage L, a zero wire passage N, a grounding passage PE, a thermistor first end passage D1 and a thermistor second end passage D2. In this embodiment, the wire of the thermistor first terminal path D1 is electrically connected to the live line so that both can share one path in the four-ring connector, thereby making the live line path in the four-ring connector a composite path L-D1 of the live line path L and the thermistor first terminal path D1. Thus, in this embodiment, the electrical conduction path formed by the four-ring connector is: a zero line passage N, a composite passage L-D1, a grounding passage PE and a thermistor second end passage D2.
Moreover, since the control switch 222 is disposed on the 220V ac live wire in the base, and the 5V dc power source is directly electrically connected to the 220V ac live wire, when the control switch 222 is turned on to heat the heating plate 211, the thermistor NTC 212 turns on the 5V dc power and starts to monitor the temperature; when the control switch 222 is turned off so that the heating plate 211 stops heating, the thermistor NTC 212 does not receive 5V dc, and thus the temperature monitoring function is no longer implemented.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
