The functions of the food processor mainly include but are not limited to: making soy milk, grinding flour, juicing, making rice paste, mincing meat, shaving ice, making coffee and / or blending mask, etc.

[0003] The existing food processor not only has the function of stirring and crushing, but also has the function of heating, and is more and more liked by consumers, but the electric control module connected with the heating disc on the existing food processor for electric control of the heating disc is mostly realized by using an electric control PCB to realize the electric control function, so that not only the production cost is high, but also the assembly production is not convenient, and thus the enterprise production cost cannot be effectively reduced and the production efficiency cannot be further improved. Therefore, the technical personnel in the field urgently need to develop a food processor with a simple switching circuit structure to meet the actual use requirements. SUMMARY

[0035] The present application will be further described in detail below by specific embodiments in conjunction with the drawings.

[0036] As Figures 1-9As shown, a simple switching circuit structure applied to a food processor, comprising an upper coupler 1, a lower coupler 2, and an on-off switch 3.

[0037] The upper coupler 1 is arranged on the blender head 200, and an insulating pin 101 is arranged on the upper coupler 1; the lower coupler 2 is arranged on the body of the food processor, and a normally closed contact power line group 201 that is normally closed and can be inserted by the insulating pin 101 to break the contact power is arranged on the lower coupler 2; the on-off switch 3 is arranged on the body of the food processor and connected with the normally closed contact power line group 201, and is used for controlling the on-off of the normally closed contact power line group 201 in the normally closed contact state.

[0038] When the blender head 200 is covered on the body of the food processor 100, the insulating pin 101 is inserted into the lower coupler 2 to mechanically cut off the normally closed contact power line group 201, so as to achieve the purpose of power-off; when the blender head 200 is removed from the body of the food processor 100, the insulating pin 101 is pulled out of the lower coupler 2, that is, the normally closed contact power line group is connected to the circuit, so that the on-off of the power circuit of the normally closed contact power line group 201 can be controlled through the on-off switch 3, thereby not only achieving the purpose of regulation and control, but also avoiding the heating disc from being always powered and heated.

[0039] Further, the normally closed contact power line group 201 comprises a normally closed front terminal 2011 and a normally closed rear terminal 2012 arranged opposite to each other, the upper end of the normally closed front terminal 2011 is in contact with the upper end of the normally closed rear terminal 2012, and a guide opening 2010 for guiding the insertion of the insulating pin 101 is formed between the upper ends of the two, and the guide opening 2010 is a trumpet opening. The advantage of adopting the trumpet opening is that it can greatly facilitate the insertion of the insulating pin 101 to cut off the normally closed front terminal 2011 and the normally closed rear terminal 2012, so as to achieve the purpose of power-off.

[0040] Further, a normally closed front rear protruding contact point 20111 protruding rearward is arranged on the rear side of the upper end of the normally closed front terminal 2011.

[0041] A normally closed rear front protruding contact point 20121 protruding forward and capable of being in contact with the normally closed front rear protruding contact point 20111 is arranged on the front side of the upper end of the normally closed rear terminal 2012.

[0042] The normally closed front rear protruding contact point 20111 and the normally closed rear front protruding contact point 20121 are both silver contact points. The advantage is that the silver contact point is made of metal silver, which has excellent conductivity.

[0043] Further, the normally closed contact power line group 201 further comprises a normally closed front terminal 203 and a normally closed rear terminal 204.

[0044] One end of the normally closed front terminal 203 is connected with the power supply terminal, and the other end is connected with the normally closed front terminal 2011; one end of the normally closed rear terminal 204 is connected with the normally closed rear terminal 2012, and the other end is connected with the on-off switch 3 input terminal;

[0045] The on-off switch 3 output terminal is connected with the heating disc arranged on the body of the food processor.

[0046] The purpose of the above-mentioned series circuit structure is to realize the series connection of the normally closed front terminal 2011 and the normally closed rear terminal 2012, the on-off switch 3 and the heating disc, so that when the blender head 200 is covered on the body of the food processor 100, the insulating pin 101 is inserted to separate the normally closed front terminal 2011 and the normally closed rear terminal 2012, so that the heating disc is in a power-off failure state;

[0047] When the blender head 200 is removed from the body of the food processor 100, the normally closed front terminal 2011 and the normally closed rear terminal 2012 are closed and contacted, and then the on-off switch 3 can be used to control whether the heating disc is powered on or not. Not only can the control purpose be achieved, but also the heating disc is always powered on.

[0048] Further, the manufacturing material of the insulating pin 101 is insulating material, preferably plastic. Its advantage is that plastic not only has excellent insulation performance, but also has outstanding thermoplasticity, which greatly facilitates actual production.

[0049] Further, the upper coupler 1 is further provided with a plurality of power connection pins 102, and the lower coupler 2 is further provided with a plug-in power line set 202 which can be plugged and matched with the power connection pins 102 for power connection. Its purpose is to meet the actual use requirements.

[0050] The application also provides a food processor comprising the simple switching circuit structure applied to the food processor as described above. When the blender head 200 is covered on the body of the food processor 100, the insulating pin 101 is inserted into the lower coupler 2, so as to achieve mechanical isolation of the normally closed power-on line set 201, thereby achieving the purpose of power-off; when the blender head 200 is removed from the body of the food processor 100, the insulating pin 101 is pulled out of the lower coupler 2, that is, the normally closed power-on line set is connected to the power circuit, so that the on-off switch 3 can be used to control the on-off action of the normally closed power-on line set 201 power connection circuit, thereby not only achieving the control purpose, but also avoiding the heating disc being always powered on.

[0051] The above describes the embodiments of the application in detail, but the application is not limited to the above-mentioned embodiments. Even if various changes are made to the application, it still falls within the protection scope of the application.
