When the motor 70 is running, it can process the food contained in the cup body 41, such as grinding, stirring, etc., and when the heater 80 is running, it can heat the food contained in the cup body 41.

[0031] like Figure 3 As shown, the food processor may further include a high-voltage switch 110 (a circuit device, Figure 1 Not shown), the power supply circuit of the strong power switch and the motor 70 and the heater 80 (which belongs to the circuit device, Figure 1 When the outer cover 20 is opened, the high-voltage switch can be driven to disconnect, so that the power supply circuit is disconnected, and the motor 70 and the heater 80 stop running. When the outer cover 20 is closed, the high-voltage switch can be driven to close, so that the power supply circuit is connected, and the motor 70 and the heater 80 can operate normally.

[0032] Compared with the prior art, in the food processing machine provided in the first embodiment of the present invention, for the strong current part, a strong current switch is provided to be connected to the power supply circuit of the motor 70 and the heater 80. When the outer cover 20 is opened, the strong current switch is disconnected to disconnect the power supply circuit, and the motor 70 and the heater 80 are powered off and stopped, thereby reducing the possibility of liquid splashing out of the food processing machine, and improving the safety of the food processing machine through the strong current switch; at the same time, for the weak current part, an outer detection component 50 is provided to detect the opening and closing state of the outer cover 20, and an inner detection component 60 is provided to detect the opening and closing state of the inner cover 42, and the safety of the food processing machine is further improved through the weak current switch, that is, the food processing machine provided in the embodiment of the present invention is provided with both a strong current switch and a weak current detection component to improve As for the safety of opening the cover of the food processing machine, even if the high-voltage switch fails, the low-voltage detection component can still turn off the motor 70 and the heater 80 in time when the cover of the food processing machine is opened. Similarly, even if the low-voltage detection component fails, the high-voltage switch can still turn off the motor 70 and the heater 80 in time when the cover of the food processing machine is opened. In addition, an external detection component 50 is respectively provided to detect the opening and closing state of the outer cover 20, and an internal detection component 60 is provided to detect the opening and closing state of the inner cover 42. The opening and closing states of the inner cover 42 and the outer cover 20 can be detected more specifically, thereby further improving the safety of opening the cover of the food processing machine. By providing triple protection of the high-voltage switch, the external detection component 50, and the internal detection component 60, the possibility of failure of the cover opening detection of the food processing machine is greatly reduced.

[0033] Furthermore, in some embodiments of the present application, the external detection component 50 can be connected to a high-voltage switch. When the high-voltage switch is disconnected, the external detection component 50 determines that the opening and closing state of the outer cover 20 is open, and when the high-voltage switch is closed, the external detection component 50 determines that the opening and closing state of the outer cover 20 is closed.

[0034] Further, in some embodiments of the present application, Figure 3As shown, the food processor may further include a control panel 90 disposed on the main body 10, and the control panel 90 is respectively connected to the external detection member 50, the internal detection member 60, the motor 70 and the heater 80. The control panel 90 may specifically obtain the opening and closing state of the external cover 20 detected by the external detection member 50 and the opening and closing state of the internal cover 42 detected by the internal detection member 60. For example, the external detection member 50 may send the corresponding external cover 20 opening signal and the external cover 20 closing signal to the control panel 90 respectively when detecting that the external cover 20 is opened and closed, or the external detection member 50 may send the corresponding port voltage to the control panel 90 respectively when the external cover 20 is opened and closed. The control panel 90 controls the motor 70 and the heater 80 to stop running when the external detection member 50 detects that the external cover 20 is opened and closed, and allows the motor 70 and the heater 80 to operate normally when the external detection member 50 detects that the external cover 20 is opened and closed. Similarly, the control board 90 controls the motor 70 and the heater 80 to stop running when the inner cover 42 is in the open and closed state detected by the inner detection member 60 and the inner cover 42 is open, and allows the motor 70 and the heater 80 to operate normally when the inner cover 42 is in the open and closed state detected by the inner detection member 60 and the inner cover 42 is closed. By setting the control board 90 to be connected to the outer detection member 50, the inner detection member 60, the motor 70 and the heater 80 respectively, the control board 90 can obtain the outer cover 20 opening and closing state and the inner cover 42 opening and closing state detected by the outer detection member 50 and the inner detection member 60, and realize the control of the motor 70 and the heater 80 according to the corresponding outer cover 20 opening and closing state and the inner cover 42 opening and closing state, which can simplify the control logic of the outer detection member 50 and the inner detection member 60 on the motor 70 and the heater 80 and reduce the cost.

[0035] In some embodiments of the present application, the internal detection member 60 may be, for example, a Hall detection board, which is connected to the control board 90. The Hall detection board may generate different Hall detection values ​​when the inner cover 42 is opened and closed and send the Hall detection values ​​to the control board 90. The control board 90 determines that the opening and closing state of the inner cover 42 is the inner cover 42 being opened when the Hall detection value sent by the internal detection member 60 is a preset detection value, and determines that the opening and closing state of the inner cover 42 is the inner cover 42 being closed when the Hall detection value sent by the internal detection member 60 is not a preset detection value. Among them, the preset detection value is a pre-set Hall detection value, which may be set when the food processor leaves the factory, or may be set by the user according to actual needs, and may be flexibly set according to actual needs.

[0036] Specifically, in some embodiments of the present application, the inner detection member 60 may also include, for example, a magnet disposed on the inner cover 42, and the magnet generates a corresponding Hall detection value on the Hall detection plate as the inner cover 42 is opened and closed. For example, when the inner cover 42 is opened, three standard units of Hall detection values ​​may be generated, and when the inner cover 42 is closed, other Hall detection values ​​may be generated.

[0037] Furthermore, in some embodiments of the present application, the cup body assembly 40 can be detachably arranged on the main body 10, and each food processor can include a plurality of different types of cup body assemblies 40. Different types of cup body assemblies 40 can correspondingly realize different food processing functions. For example, it can include a grinding cup for grinding and crushing solid food, a heating cup for heating and boiling liquid food, a multi-functional cup for grinding and heating and boiling solid-liquid mixed food, etc. The specific settings can be made according to actual needs.

[0038] For multiple different types of cup body assemblies 40, the control board 90 can determine the type of the cup body 41 of the cup body assembly 40 currently installed on the main body 10 according to the Hall detection value of the Hall detection board. That is, different types of cup body assemblies 40 send different Hall detection values ​​to the control board 90. By determining the type of the cup body 41 of the cup body assembly 40 currently installed on the main body 10 through the Hall detection value, the motor 70 and the heater 80 can be better controlled according to different types of cup bodies 41, thereby improving the food processing effect of the food processor.

[0039] Specifically, in some embodiments of the present application, different magnets can be arranged in different types of cup body assemblies 40 , and the Hall detection board can generate different Hall detection values ​​when detecting different magnets, thereby realizing the detection of the type of cup body 41 of the cup body assembly 40 .

[0040] Specifically, in some embodiments of the present application, for different types of cup body assemblies 40, the Hall detection values ​​generated by different types of cup body assemblies 40 when the lid is opened are the same, and the Hall detection values ​​generated when the lid is closed are different. Different types of cup body assemblies 40 generate the same Hall detection value when the lid is opened. Regardless of the type of cup body assembly 40, the control board 90 can accurately determine that the inner cover 42 of the cup body 41 is in the open state, thereby reducing the occurrence of misjudgments and further improving the safety of the food processor.

[0041] Furthermore, in some embodiments of the present application, the food processor may further include a display panel 100 disposed on the main body 10, and the display panel 100 may display the processing status and related processing parameters of the food processor, such as the current temperature, the remaining processing time, etc. The display panel 100 is connected to the control panel 90, and the control panel 90 controls the display panel 100 to issue an outer cover 20 opening alarm when the outer cover 20 is opened, and controls the display panel 100 to issue an inner cover 42 opening alarm when the inner cover 42 is opened. By issuing an alarm on the opening of the outer cover 20 and the inner cover 42 through the display panel 100, the user can be better reminded, the possibility of the user being scalded by the hot food in the food processor is reduced, and the safety of the food processor is further improved.

[0042] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
