[0064] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application environment according to an exemplary embodiment, such as... Figure 1 As shown, the application environment may include server 01 and terminal 02.

[0065] In an optional embodiment, server 01 can be used for computational processing in the integrated stove duct radiation noise processing method. Specifically, server 01 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

Optionally, the operating system running on the electronic device can be, but is not limited to, Android, iOS, Linux, Windows, and Unix systems.

[0067] For example, the terminal 02 acquires the motion signal corresponding to the valve stem of the stove ignition valve and the valve switch signal corresponding to the stove ignition valve, and transmits them to the server 01; the server 01 performs signal conversion processing on the motion signal to obtain the corresponding linkage indication signal, which is used to drive the state analysis module to perform state analysis processing on the valve switch signal to obtain the stove state signal; based on the stove state signal, the on / off state of the range hood is controlled.

[0068] In addition, it should be noted that, Figure 1 The example shown is merely one application environment provided by this disclosure; in practical applications, other application environments may also be included.

[0069] In the embodiments described in this specification, the server 01 and the terminal 02 can be directly or indirectly connected through wired or wireless communication, and this disclosure does not impose any restrictions.

[0070] Figure 2 This is a schematic diagram illustrating a method for controlling the linkage between a range hood and a stove, according to an exemplary embodiment. Figure 2 As shown, the method for controlling the linkage between the range hood and the stove includes:

[0071] Step S201: Obtain the motion signal corresponding to the valve stem of the stove ignition valve and the valve opening / closing signal corresponding to the stove ignition valve.

[0072] In this embodiment of the disclosure, when the user ignites, changes the flame intensity, or turns off the stove through the ignition valve, the valve stem of the ignition valve will move simultaneously. The motion signal corresponding to the valve stem of the ignition valve can be a signal indicating that the valve stem moves up and down.

[0073] Step S202: Perform signal conversion processing on the motion signal to obtain the corresponding linkage indication signal. The linkage indication signal is used to drive the state analysis module to perform state analysis processing on the valve switch signal to obtain the stove state signal.

[0074] In this embodiment, the linkage indication signal is an electrical signal. The linkage indication signal drives the state analysis module by providing the state analysis module with the electrical energy required for its state analysis processing. The state analysis module does not consume power when no linkage indication signal is received.

[0075] In an optional embodiment, such as Figure 3 As shown, the motion signal undergoes signal conversion processing to obtain the corresponding linkage indication signal, including:

[0076] Step S2021: Perform electromagnetic conversion processing on the motion signal to obtain the corresponding electrical signal.

[0077] In this embodiment of the disclosure, the electromagnetic conversion processing of the motion signal can be performed by placing a magnet on and fixing it to the valve stem, allowing the magnet to move with the valve stem. A generator coil is placed around the magnet. When the valve stem moves up and down, the magnet moves accordingly, changing the magnetic field within the generator coil and causing it to generate a current, which is the corresponding electrical signal.

[0078] Step S2022: Rectify, limit, and filter the electrical signal to obtain the corresponding linkage indication signal.

[0079] In this embodiment, the electrical signal is alternating current (AC). Therefore, the electrical signal is rectified, amplitude-limited, and filtered to convert it into direct current (DC). Rectifying, amplitude-limiting, and filtering the electrical signal allows it to be connected to a rectification, amplitude-limiting, and filtering circuit to obtain the corresponding DC signal, i.e., the linkage indication signal.

[0080] As can be seen from the above, the embodiments of this disclosure can convert the motion signal into a corresponding electrical signal by performing electromagnetic conversion processing, thereby converting the magnetic variable into an electrical variable. By performing rectification, amplitude limiting and filtering processing on the electrical signal, a corresponding linkage indication signal can be obtained, which can drive the state analysis module in the form of DC power and provide the power required by the state analysis module.

[0081] In an optional embodiment, such as Figure 4 As shown, the method also includes:

[0082] Step S301: When the valve switch signal indicates that the stove ignition valve is open, determine the transition information corresponding to the valve switch signal.

[0083] In this embodiment of the disclosure, after the ignition valve of the stove is opened, the user will adjust the valve to adjust the flame or turn off the flame. Therefore, when the valve switch signal indicates that the ignition valve of the stove is open, the corresponding transition information of the valve switch signal is determined.

[0084] Step S302: When the valve jumps to the closed position as indicated by the jump information, a stove turn-off signal is generated. The stove turn-off signal is a stove status signal.

[0085] Step S303: If the valve indicating the transition information does not transition to closed, a stove ignition signal is generated. The stove ignition signal is a stove status signal.

[0086] Step S304: When the valve switch signal indicates that the ignition valve of the stove is closed, generate a stove ignition off signal.

[0087] As can be seen from the above, the embodiments of this disclosure generate different signals according to the different valve states indicated by the valve switch signals, which can realize the issuance of different linkage indication signals to the range hood according to the different meanings of the valve switch signals, thus facilitating the linkage between the stove and the range hood.

[0088] Step S203: Based on the stove status signal, control the on / off state of the range hood.

[0089] In this embodiment of the present disclosure, when the stove status signal is a stove ignition signal, the range hood is controlled to be in an on state, and when the stove status signal is a stove ignition signal, the range hood is controlled to be in a off state.

[0090] In one specific implementation, the switch-on linkage control logic is as follows: Figure 5 As shown, after the linkage indication signal is generated, the state analysis module is powered on and performs state analysis on the valve switch signal. When the valve switch signal indicates that the stove ignition valve is open, the module determines the corresponding transition information of the valve switch signal. When the transition information indicates that the valve has transitioned to closed, the module generates a stove turn-off signal to control the range hood to turn off. When the transition information indicates that the valve has not transitioned to closed, the module generates a stove turn-on signal to control the range hood to turn on. When the valve switch signal indicates that the stove ignition valve is closed, the module generates a stove turn-off signal to control the range hood to turn off.

[0091] In an exemplary embodiment, a range hood and cooktop linkage control device is also provided. This device includes an acquisition module, a signal conversion module, and a control module, wherein...

[0092] The acquisition module is used to acquire the motion signal corresponding to the valve stem of the stove ignition valve and the valve opening / closing signal corresponding to the stove ignition valve.

[0093] The signal conversion module is used to convert motion signals to obtain corresponding linkage indication signals. The linkage indication signals are used to drive the state analysis module to perform state analysis and processing on valve switch signals to obtain stove state signals.

[0094] The control module is used to control the on / off state of the range hood based on the stove status signal.

[0095] In an optional embodiment, the signal conversion module includes:

[0096] The electromagnetic conversion module is used to perform electromagnetic conversion processing on motion signals to obtain corresponding electrical signals;

[0097] The rectification, limiting, and filtering module is used to rectify, limit, and filter electrical signals to obtain corresponding linkage indication signals.

[0098] In an optional embodiment, the apparatus further includes:

[0099] The first signal processing module is used to determine the transition information corresponding to the valve switch signal when the valve switch signal indicates that the ignition valve of the stove is open;

[0100] The second signal processing module is used to generate a stove shut-off signal when the valve jumps to the closed position according to the jump information indication. The stove shut-off signal is a stove status signal.

[0101] The third signal processing module is used to generate a stove ignition signal when the valve indicated by the jump information does not jump to the closed position. The stove ignition signal is a stove status signal.

[0102] The fourth signal processing module is used to generate a stove turn-off signal when the valve switch signal indicates that the stove ignition valve is closed.

[0103] In an exemplary embodiment, an electronic device is also provided, including: a processor; and a memory for storing processor-executable instructions; wherein the processor is used for the instructions to implement the range hood and stove linkage control method as described in the embodiments of this disclosure.

[0104] In an exemplary embodiment, a storage medium is also provided, which, when the instructions in the storage medium are executed by the processor of an electronic device, enables the electronic device to execute the range hood and stove linkage control method in the embodiments of this disclosure.

[0105] Secondly, this disclosure also provides a range hood and stove linkage system for implementing the above-mentioned range hood and stove linkage control method.

[0106] The system includes a cooktop transmitting and processing module and a range hood receiving and processing module.

[0107] like Figure 6 As shown, the stove emission processing module includes a power generation module 1, a valve detection module 2, and a status analysis module 3. The power generation module 1 is electrically connected to the status analysis module 3, and the valve detection module 2 is electrically connected to the status analysis module 3.

[0108] The power generation module 1 is mounted on the valve stem of the stove ignition valve. The power generation module 1 is used to acquire the motion signal corresponding to the valve stem and perform signal conversion processing on the motion signal to obtain the corresponding linkage indication signal.

[0109] Valve detection module 2 is electrically connected to the ignition valve of the stove. Valve detection module 2 is used to obtain the valve switch signal corresponding to the ignition valve of the stove.

[0110] The status analysis module 3 is used to perform status analysis processing on the valve switch signal under the drive of the linkage indication signal, obtain the stove status signal, and transmit the stove status signal to the range hood receiving and processing module.

[0111] The range hood receiving and processing module is used to acquire the cooktop status signal and control the on / off state of the range hood based on the cooktop status signal.

[0112] Based on the above, this embodiment of the present disclosure, by mounting the power generation module 1 on the valve stem of the stove ignition valve, can easily acquire the motion signal corresponding to the valve stem, thereby enabling signal conversion processing of the motion signal to obtain the corresponding linkage indication signal; by electrically connecting the valve detection module 2 to the valve of the stove ignition valve, it can easily acquire the valve switch signal corresponding to the stove ignition valve; by performing state analysis processing on the valve switch signal under the drive of the linkage indication signal through the state analysis module 3, the stove state signal is obtained; and the range hood receiving and processing module controls the switch state of the range hood based on the stove state signal, thus realizing stove linkage.

[0113] In an optional embodiment, such as Figure 6 As shown, the status analysis module 3 includes: an RF transmitter chip, a transmitter antenna, a resistor R1, and a transistor Q1.

[0114] The radio frequency (RF) transmitter chip is electrically connected to the power generation module 1 and the valve detection module 2; the transmitting antenna is electrically connected to the RF transmitter chip; one end of resistor R1 is connected to the DC power supply VDD, and the other end of resistor R1 is connected to the collector of transistor Q1; the collector of transistor Q1 is connected to the first interface of the RF transmitter chip, the emitter of transistor Q1 is connected to the third interface of the RF transmitter chip, and the valve detection module 2 is connected between the base and emitter of transistor Q1.

[0115] In this embodiment, the radio frequency (RF) transmitter chip is driven by a linkage indication signal provided by the power generation module 1. Under the drive of the linkage indication signal, it performs state analysis processing on the valve switch signal provided by the valve detection module 2 to obtain the cooktop status signal. The transmitting antenna is used to transmit the cooktop status signal to the range hood receiving and processing module. It should be noted that other auxiliary circuit modules required for the operation of the RF transmitter chip are not shown in the figure.

[0116] In an optional embodiment, such as Figure 6 As shown, the valve detection module 2 includes: a first clamp and a second clamp; the base of the transistor is connected to the positive terminal of the valve's power supply through the first clamp, and the emitter of the transistor is connected to the negative terminal of the valve's power supply through the second clamp.

[0117] In this embodiment of the present disclosure, both the first clamp and the second clamp are clamps with piercing function. The power supply of the valve is +1.5V or +3V. The piercing position of the first clamp can be the connection line between the positive terminal of the power supply of the valve and the valve, and the piercing position of the second clamp can be the connection line between the negative terminal of the power supply of the valve and the valve.

[0118] As can be seen from the above, in this embodiment of the present disclosure, by connecting the base of the transistor to the positive terminal of the valve's power supply through a first clamp and connecting the emitter of the transistor to the negative terminal of the valve's power supply through a second clamp, the line for acquiring the valve switch signal can be connected in parallel to the valve's power supply line, so that the state analysis module 3 can acquire the corresponding valve switch signal based on the changes in the electrical signal on the valve's power supply line.

[0119] In an optional embodiment, the power generation module 1 includes: a magnet 101, a power generation coil 102, and a rectification, limiting, and filtering circuit 103;

[0120] like Figure 7 As shown, magnet 101 is sleeved on valve stem and moves with the movement of valve stem; generator coil 102 is sleeved outside magnet 101 and is electrically connected to rectifier limiting filter circuit 103.

[0121] In this embodiment, the assembly method of the magnet 101 and the generator coil 102 with the valve stem is as follows: the seat of the generator coil 102 is fixed on the body of the ignition valve; the magnet 101 is inserted into the valve stem, but not completely inserted to the bottom. Because the valve stem has a downward stroke during ignition, the height of the seat is aligned with the upper scale line of the magnet 101 and then fixed on the valve stem. A clamp or clip can be used to fix it so that it will not slide up and down, so as to ensure that the valve stem and the electromagnet are integrated and move synchronously.

[0122] As can be seen from the above, by fitting the magnet 101 onto the valve stem of the stove ignition valve, this embodiment of the present disclosure can easily acquire the motion signal corresponding to the valve stem, so as to realize the signal conversion processing of the motion signal and obtain the corresponding linkage indication signal.

[0123] In an optional embodiment, such as Figure 6 As shown, the rectifier limiting filter circuit 103 is electrically connected to the state analysis module 3. The rectifier limiting filter circuit 103 includes: a first diode, a second diode, a third diode, a fourth diode, and a capacitor C1.

[0124] In this embodiment, the first diode, second diode, third diode, and fourth diode together form a rectifier module DB1. The anode of the first diode is connected to the anode of the fourth diode, the cathode of the first diode is connected to the anode of the second diode, the cathode of the second diode is connected to the cathode of the third diode, and the anode of the third diode is connected to the cathode of the fourth diode. The first connection terminal of the generator coil 102 is connected to the cathode of the first diode, and the second connection terminal of the generator coil 102 is connected to the cathode of the fourth diode. The anode of the first diode is connected to the cathode of a capacitor, and the cathode of the second diode is connected to the anode of capacitor C1. The anode of capacitor C1 is connected to the second interface of the RF transmitter chip, and the cathode of capacitor C1 is connected to the third interface of the RF transmitter chip. The anode of capacitor C1 is also connected to the DC power supply VDD, and the cathode of capacitor C1 is grounded.

[0125] As can be seen from the above, the present invention, through the connection between the first diode, the second diode, the third diode, the fourth diode and the capacitor C1, can rectify and filter the AC power generated by the generator coil to obtain DC power, so as to drive the radio frequency transmitter chip.

[0126] In an optional embodiment, such as Figure 6 As shown, the rectifier limiting filter circuit 103 also includes: a Zener diode ZD1; the Zener diode ZD1 is connected in parallel with the capacitor C1.

[0127] In this embodiment, the positive terminal of Zener diode ZD1 is connected to the negative terminal of capacitor C1, and the negative terminal of Zener diode ZD1 is connected to the positive terminal of capacitor C1. The alternating current generated by the generator coil 102 is rectified by the rectifier module and stored in capacitor C1. When the charge stored in capacitor C1 reaches a certain level, the generated voltage reaches the operating voltage VDD of the RF module chip, and the RF chip starts to work. By clamping the voltage VDD through Zener diode ZD1, overcharging of capacitor C1 can be prevented.

[0128] In an optional embodiment, such as Figure 7 As shown, the stove's emission processing module is assembled with the stove as follows: a magnet is sleeved on the valve stem, a generator coil is sleeved on the outside of the magnet, the radio frequency module is attached to the bottom of the stove's glass, the rectifier limiting filter circuit 103 and the status analysis module 3 are encapsulated in the radio frequency module, and the positive and negative terminals of the valve power supply are connected to the status analysis module 3 through the valve detection module 2, i.e., the wire clamp with piercing function.

[0129] In an optional embodiment, such as Figure 8 As shown, the processing logic of the stove transmitting processing module is as follows: after the rectification and limiting filter circuit generates the electrical signal corresponding to the linkage indication signal, the radio frequency transmitting chip starts to work, analyzes the ignition valve switch signal, obtains the stove status signal, and transmits it to the range hood receiving processing module by the transmitting antenna.

[0130] In an optional embodiment, such as Figure 9 As shown, the range hood receiving and processing module includes: a receiving antenna, an RF receiving chip, and a cooktop status signal processor; the receiving antenna is electrically connected to the RF receiving chip, the RF receiving chip is electrically connected to the cooktop status signal processor, and the cooktop status signal processor is electrically connected to the range hood control circuit.

[0131] In this embodiment, the range hood receiving and processing module is attached to the range hood. The receiving antenna receives the cooktop status signal transmitted by the transmitting antenna, and the receiving antenna is electrically connected to the radio frequency receiving chip to transmit the signal.
