[0047] Embodiment one

[0048] Please refer to Figure 1 , Figure 1 is a structure schematic view of a head monitoring device applied to a complementary food machine disclosed by the embodiment one of the present application. The head monitoring device can be integrated in the complementary food machine, or can be used as a detachable component as an auxiliary device of the complementary food machine, and the specific application of the present application is not limited. As shown in Figure 1 , the complementary food machine includes a complementary food machine body and a head; the head monitoring device includes a head coupler 10, a filter circuit 20, a signal conversion circuit 30 and a main control module 40, wherein:

[0049] The first end of the head coupler 10 is electrically connected with the first end of the filter circuit 20, and the second end of the head coupler 10 is connected with the head. The head coupler 10 is used for collecting the working state signal of the head, and providing the working state signal to the filter circuit 20.

[0050] The second end of the filter circuit 20 is electrically connected with the first end of the signal conversion circuit 30, and the second end of the signal conversion circuit 30 is electrically connected with the main control module 40. The signal conversion circuit 30 is used for converting the working state signal into a target electric signal and providing the target electric signal to the main control module 40. The main control module 40 is used for controlling the working state of the complementary food machine body according to the target electric signal received from the signal conversion circuit 30.

[0051] In the embodiment of the present application, the head monitoring device can be integrated in the complementary food machine, or can be used as a detachable component as an auxiliary device of the complementary food machine.

[0052] In the embodiment of the utility model, the second end of the head coupler 10 is electrically connected with the head, the head coupler 10 is used for collecting the working state signal of the head, and the working state signal is provided to the filter circuit, which can be set as: the head coupler 10 is electrically connected with the head, and is affected differently in the two states of opening and closing of the head, so that the head coupler 10 sends the first electric signal to the filter circuit 20 when the head is in the open state, and sends the second electric signal to the filter circuit 20 when the head is in the closed state.

[0053] In the embodiment of the utility model, the second end of the filter circuit 20 is electrically connected with the first end of the signal conversion circuit 30, and is used for corresponding filtering operation on the electric signal transmitted in the circuit. In the embodiment of the utility model, the main control module 40 is generally a processor chip, and the electric signal that can be received also needs to be an electric signal that can be recognized by the processor chip. Therefore, the second end of the signal conversion circuit 30 after filtering is electrically connected with the main control module 40, the signal conversion circuit 30 performs signal conversion on the electric signal after filtering, so as to send the electric signal meeting the recognition requirement of the main control module 40 to the main control module 40, so that the main control module 40 controls the working state of the complementary food machine body according to the target electric signal received from the signal conversion circuit 30, for example: when the main control module 40 judges that the head is in the open state according to the target electric signal received from the signal conversion circuit 30, the complementary food machine body stops the current work or enters the pause state; when the main control module 40 judges that the head is in the closed state according to the target electric signal received from the signal conversion circuit 30, the complementary food machine body starts working or closes the pause state.

[0054] It can be seen that the head monitoring device applied to the complementary food machine in the utility model can collect the working state signal of the head through the head coupler 10, provide the working state signal to the filter circuit 20, for example: send the first electric signal to the filter circuit 20 when the head is in the open state, send the second electric signal to the filter circuit 20 when the head is in the closed state, then send the target electric signal to the main control module 40 after filtering and signal conversion operation on the electric signal in the circuit, finally the main control module 40 controls the working state of the complementary food machine body according to the target electric signal: stop working or start working, thereby improving the use safety of the existing complementary food machine.

[0055] In an optional embodiment, as shown in Figure 2 The filter circuit 20 includes a diode D8 and a second resistor R45, and the signal conversion circuit 30 includes a first resistor R44, a third resistor R47 and a triode Q4, wherein:

[0056] The head coupler 10 is electrically connected with the anode of the diode D8, and the head coupler 10 is used for sending a first electric signal to the diode D8 when the head is in an open state and sending a second electric signal to the diode D8 when the head is in a closed state;

[0057] The cathode of the diode D8 is electrically connected with the first end of the second resistor R45, and the second end of the second resistor R45 is electrically connected with the base of the triode Q4;

[0058] The first end of the third resistor R47 is electrically connected with the base of the triode Q4, and the second end of the third resistor R47 is used for grounding;

[0059] The first end of the first resistor R44 is used for receiving an input power supply, the second end of the first resistor R44 is electrically connected with the collector of the triode Q4, and the emitter of the triode Q4 is used for grounding;

[0060] The first end of the main control module 40 is electrically connected with the collector of the triode Q4, and the main control module 40 is used for controlling the working state of the body of the complementary food machine according to the target electric signal received from the collector of the triode Q4.

[0061] In the embodiment of the utility model, the core device of filter circuit 20 is diode D8, and the core device of signal conversion circuit 30 is triode Q4. Optionally, the working process of the head monitoring device in the utility model can be as follows:

[0062] The head coupler 10 sends a low-level signal to the filter circuit 20 when the head is in an open state and sends an alternating current signal with a preset frequency and amplitude to the filter circuit 20 when the head is in a closed state.

[0063] For the head in an open state: the low-level signal cannot affect the diode D8 and the triode Q4, so that the base of the triode Q4 receives a low-level signal, the triode Q4 cannot be turned on, and the signal of the collector of the triode Q4 is consistent with the signal of the input power supply, for example, the signal of the input power supply is set as a 5V direct current voltage signal, so that the first end of the main control module 40 is electrically connected with the collector of the triode Q4, and the target electric signal received is a 5V direct current voltage signal.

[0064] For the case that the head is in the closed state: the AC signal is filtered after passing through the diode D8, and the negative half-cycle signal in the AC signal is filtered out, becoming a periodic electric signal. The periodic electric signal reaches the base of the transistor Q4, causing the base of the transistor Q4 to be periodically turned on. Once the transistor Q4 is turned on, the collector voltage of the transistor Q4 will be consistent with the emitter (ground) voltage, that is, 0V, and once the transistor Q4 is not turned on, the signal at the collector of the transistor Q4 will be consistent with the signal of the input power supply. For example, if the signal of the input power supply is set to a 5V DC voltage signal, the signal at the collector of the transistor Q4 will also be a 5V DC voltage signal. Since the transistor Q4 is periodically turned on, the signal at the collector of the transistor Q4 is a periodic signal between 5V and 0V. The first end of the main control module 40 is electrically connected to the collector of the transistor Q4, and the target electric signal received is a periodic signal between 5V and 0V.

[0065] For the main control module 40, it can be set to determine that the head is in the open state when the target electric signal received by the first end of the main control module 40 is a 5V DC voltage signal, and determine that the head is in the closed state when the target electric signal received by the first end of the main control module 40 is a periodic signal between 5V and 0V.

[0066] As can be seen, in this optional embodiment, the diode D8 can realize the filtering operation of the circuit, the transistor Q4 can realize the signal conversion operation of the circuit, and the first end of the main control module 40 is electrically connected to the collector of the transistor Q4, so as to control the working state of the food processor body according to the target electric signal received from the collector of the transistor Q4. Since the food processor generally uses an AC signal as the power supply, it is more convenient to directly use an AC signal as the input. The combination of the diode D8 and the transistor Q4 makes the circuit structure simple and stable. In summary, the head monitoring device for the food processor in this optional embodiment reduces the cost of the monitoring device and improves the convenience of use.

[0067] In yet another optional embodiment, the second end of the head coupler 10 is connected to the head, specifically comprising:

[0068] The second end of the head coupler 10 is connected to the head, so that the head coupler 10 is switched to the uncoupled state when the head body is in the open state, and is switched to the coupled state when the head body is in the closed state;

[0069] And the head coupler 10 is configured to send a first electric signal to the diode D8 when the head is in the open state, and send a second electric signal to the diode D8 when the head is in the closed state, specifically comprising:

[0070] The nosepiece coupler 10 is configured to send a first electrical signal to the diode D8 when in the uncoupled state and a second electrical signal to the diode D8 when in the coupled state.

[0071] In this alternative embodiment, the nosepiece coupler 10 can be a three-pin coupler, with the N pin being arranged on the nosepiece. When the nosepiece is open, the N pin is pulled out, and when the nosepiece is closed, the N pin is inserted. The pulling out and insertion of the N pin will cause the three-pin coupler to generate different electrical signals, thereby causing the nosepiece coupler 10 to send a first electrical signal to the filter circuit 20 when the nosepiece is open and a second electrical signal to the filter circuit 20 when the nosepiece is closed.

[0072] It can be seen that, in this alternative embodiment, the opening and closing of the nosepiece are better reflected by the changes in electrical signals through the correspondence between the opening and closing states of the nosepiece and the coupled and uncoupled states of the coupler.

[0073] In yet another alternative embodiment, as shown in Figure 3 the nosepiece monitoring device further comprises an alarm module 50, wherein:

[0074] The alarm module 50 is electrically connected to the second end of the main control module 40, and the alarm module 50 is configured to issue an alarm prompt according to the alarm control signal of the main control module 40 when the main control module 40 detects that the nosepiece is in the open state.

[0075] In yet another alternative embodiment, as shown in Figure 4 the nosepiece monitoring device further comprises a first capacitor C17, wherein:

[0076] The first end of the first capacitor C17 is electrically connected to the emitter of the triode Q4, and the second end of the first capacitor C17 is electrically connected to the collector of the triode Q4.

[0077] In this alternative embodiment, one of the functions of the first capacitor C17 is that, when the triode Q4 is not conducting, the target electrical signal received by the main control module 40 is consistent with the input power signal. Once the input power signal fluctuates sharply, for example, suddenly increases, it may cause damage to the main control module 40. Therefore, the first end of the first capacitor C17 is electrically connected to the emitter of the triode Q4, and the second end of the first capacitor C17 is electrically connected to the collector of the triode Q4. When the input power suddenly increases, the first capacitor C17 is broken down to timely conduct the current, preventing the main control module 40 from being damaged.

[0078] In yet another alternative embodiment, as shown in Figure 5 the nosepiece monitoring device further comprises an AC power input module 60 and a low-voltage input power module 70, wherein:

[0079] The first end of the AC power input module 60 is used for connecting with an external AC power supply, the second end of the AC power input module 60 is electrically connected with the third end of the main control module 40, so that the AC power input module 60 supplies power for the main control module 40; the third end of the AC power input module 60 is electrically connected with the first end of the low-voltage input power module 70, so that the AC power input module 60 supplies power for the low-voltage input power module 70.

[0082] The first end of the current detection circuit 80 is electrically connected with the second end of the AC power input module 60, and the second end of the current detection circuit 80 is electrically connected with the third end of the main control module 40, so that the current detection circuit 80 detects the power supply of the AC power input module 60 for the main control module 40, improving the safety of power supply.

[0083] In yet another optional embodiment, as shown in Figure 6 The handpiece monitoring device further comprises a motor control circuit 90 and a heating control circuit 100, wherein:

[0084] The first end of the motor control circuit 90 is electrically connected with the fourth end of the AC power input module 60, the second end of the motor control circuit 90 is electrically connected with the fourth end of the main control module 40, and the third end of the motor control circuit 90 is used for electrically connecting with the motor, so that the motor control circuit 90 controls the operation of the motor in response to the instruction of the main control module 40;

[0085] The first end of the heating control circuit 100 is electrically connected with the fifth end of the AC power input module 60, the second end of the heating control circuit 100 is electrically connected with the fifth end of the main control module 40, and the third end of the heating control circuit 100 is used for electrically connecting with the heating device, so that the heating control circuit 100 controls the operation of the heating device in response to the instruction of the main control module 40.

[0086] In this optional embodiment, the motor is usually used to realize the stirring function of the complementary food machine, and the heating device is usually used to realize the heating function of the complementary food machine, but when the handpiece is opened, both the heating and stirring actions of the complementary food machine can pose a safety hazard to the operator, so in this optional embodiment, the main control module 40 can determine the opening or closing of the handpiece according to the target electrical signal, thereby controlling the motor or the heating device to perform corresponding operations.

[0087] In yet another optional embodiment, as shown in Figure 7As shown, the nose monitoring device further comprises a touch button circuit 110, a display circuit 120 and a power-off memory module 130, wherein:

[0088] The touch button circuit 110 is electrically connected to the sixth end of the main control module 40, and is used for converting the touch and / or button operation of the user into corresponding operation electric signals and sending the operation electric signals to the main control module 40; the touch button circuit 110 can be composed of a capacitive touch sensor or a resistive touch sensor combined with a corresponding driving circuit.

[0090] The power-off memory module 130 is electrically connected to the eighth end of the main control module 40, and is used for protecting the data of the main control module 40 when the main control module 40 is suddenly powered off. The power-off memory module 130 can include a non-volatile memory and a farad capacitor, and by using the delay discharge characteristic of the farad capacitor, the data to be protected is stored in the non-volatile memory when the system is powered off.
