TECHNICAL FIELD
[0001] The utility model relates to a technical field of gas valve switch, especially relates to a gas valve switch connecting structure. BACKGROUND
[0002] Gas stove is a tool commonly used in life for cooking, and a double-burner gas stove is usually used in a family. The burner is connected with a gas valve, and the gas valve controls ignition and flame size. The conventional gas valve usually has only one switch for controlling ignition, which triggers the igniter to ignite when starting. With the increasing of the intelligence and diversification of the functions of the gas stove, such as smoke stove linkage, flame indication, Bluetooth and other functions. To realize these functions, an additional switch is usually added to the gas valve to provide a control signal besides the conventional switch for controlling ignition. The conventional double-switch valve usually has one switch for ignition signal and one switch for providing signals for other functions, and the ignition signal is received by two different ports of the controller. However, the line connection is more complex, and the valve cost is high.
[0003] If a valve switch connecting structure can be developed to provide a function signal without increasing the cost of the switch and ensure signal stability to realize the diversification and intelligence of the functions of the gas stove, the problems of the prior art can be well solved. INVENTION CONTENTS
[0004] The utility model solves the technical problem of overcoming the prior art, and provides a valve switch connecting structure with simple line connection, low cost and good stability.
[0005] The utility model adopts the technical scheme: the utility model discloses a first switch assembly and a second switch assembly and a controller are arranged on two gas valves respectively, a first ignition signal input end, an additional function signal input end and a second ignition signal input end are arranged on the controller, the contact of the first switch assembly and the contact of the second switch assembly are matched with the valve rod on the corresponding gas valve, one end of the first switch assembly is connected with the first ignition signal input end and the additional function signal input end, the other end of the first switch assembly is grounded, one end of the second switch assembly is connected with the additional function signal input end and the second ignition signal input end, the other end of the second switch assembly is grounded, and a unidirectional diode is arranged between the additional function signal input end and the first switch assembly and the second switch assembly.
[0006] As can be seen from the above scheme, by connecting the additional function signal end and the ignition signal input end to the corresponding switch assembly at the same time, the controller obtains the starting state of the gas valve while triggering the ignition signal. Relative to the double switch structure, the overall cost can be saved, and at the same time, it can ensure that the function feedback can be performed after any burner is started, thereby realizing that the gas stove is working, the range hood is linked, and the additional functions such as starting Bluetooth are realized. In addition, by arranging the unidirectional diode between the additional function signal input end and the first switch assembly and the second switch assembly, the ignition signal can be prevented from interfering with each other.
[0007] One preferred scheme is that the anode of the unidirectional diode is connected with the additional function signal input end.
[0008] One preferred scheme is that the controller comprises a first control unit and a second control unit, the first ignition signal input end and the second ignition signal input end are arranged on the first control unit, and the additional function signal input end is arranged on the second control unit.
[0009] One preferred scheme is that the contact of the first switch assembly and the contact of the second switch assembly are both provided with a protrusion, and the valve rod is provided with a trigger disc matched with the protrusion. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 2 is a sectional view of the utility model. DETAILED DESCRIPTION
[0012] Example one:
[0013] As Figure 1 shown, in the present embodiment, the utility model includes a first switch assembly 1 and a second switch assembly 2 arranged on two gas valves respectively and a controller 3, the controller 3 is provided with a first ignition signal input end 4, an additional function signal input end 5 and a second ignition signal input end 6, the contact of the first switch assembly 1 and the contact of the second switch assembly 2 are matched with the valve rod on the corresponding gas valve, one end of the first switch assembly 1 is connected with the first ignition signal input end 4 and the additional function signal input end 5, the other end of the first switch assembly 1 is grounded, one end of the second switch assembly 2 is connected with the additional function signal input end 5 and the second ignition signal input end 6, the other end of the second switch assembly 2 is grounded, and the additional function signal input end 5 is provided with a unidirectional diode 7 between the first switch assembly 1 and the second switch assembly 2.
[0014] In this embodiment, the positive terminal of the unidirectional diode 7 is connected to the additional function signal input terminal 5. The unidirectional diode 7 isolates the ignition signal, preventing interference between the first ignition signal input terminal 4 and the second ignition signal input terminal 6.
[0015] In this embodiment, both the contacts of the first switch assembly 1 and the contacts of the second switch assembly 2 are provided with protrusions, and the valve stem is provided with a trigger disk 8 that cooperates with the protrusions. The switching assembly is triggered and turned on through the cooperation of the protrusions and the trigger disk 8.
[0016] During operation, the rotation of the valve stem drives the trigger disc 8 to rotate, which in turn presses the protrusion, causing the corresponding contact to be pressed and the switching assembly to conduct. The first ignition signal input terminal 4 and the second ignition signal input terminal 6 generate a high level when the corresponding switching assembly is on, thereby triggering the igniter to start ignition by the controller 3. After activation, the trigger disc 8 continuously presses the switching assembly. The controller 3 obtains the status of the corresponding gas valve through the additional function signal input terminal 5, and then performs functions such as corresponding range hood and stove linkage, flame indication of the corresponding gas valve, and status feedback via Bluetooth communication.
[0017] Example 2:
[0018] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the controller 3 includes a first control unit 31 and a second control unit 32, the first ignition signal input terminal 4 and the second ignition signal input terminal 6 are both disposed on the first control unit 31, and the additional function signal input terminal 5 is disposed on the second control unit 32.
[0019] Depending on the type of electronic control, the ignition function control and the additional function control can be independent, thereby meeting the working needs of the gas stove.
[0020] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
