For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0056] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0057] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances associated with a specific value caused by manufacturing, assembly, use, etc. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints.

[0060] Figure 1A schematic diagram of the structure of the gas stove in the first state provided by an embodiment of the present application is shown. Figure 2 The schematic diagram of the structure of the gas stove in the second state provided by the embodiment of the present application is shown. Figure 1 to Figure 2 As shown, the gas stove includes a base 100, a burner head 200, an outer fire cover 300 and an inner fire cover 400. The burner head 200 is installed on the base 100; the outer fire cover 300 is arranged outside the outer ring ejection tube of the burner head 200; the inner fire cover 400 is arranged outside the central ejection tube of the burner head 200, and the inner fire cover 400 has an ignition hole 401 and a main fire hole 402 located above the ignition hole 401.

[0061] The gas stove provided in the present application also includes an ignition mechanism, which includes an ignition needle 2 and a thermocouple 1. The ignition needle 2 and the thermocouple 1 are both installed on the base 100 and located between the inner fire cover 400 and the outer fire cover 300. After the ignition needle 2 discharges, it ignites the gas in the main fire hole 402 through the ignition hole 401. The thermocouple 1 cooperates with the solenoid valve to realize flameout protection of the gas stove to improve the safety of the gas stove.

[0062] In the related art, there are the following risks: due to installation errors of the ignition needle 2 or accidental collisions during use, the ignition needle 2 deviates from the optimal ignition position, resulting in poor ignition, and flame separation is prone to occur at the ignition hole 401, making it impossible for the thermocouple 1 to sense and absorb the valve normally.

[0063] Figure 3 A cross-sectional schematic diagram of a gas stove in a first state provided by an embodiment of the present application is shown. Figure 4 FIG. 2 shows a cross-sectional schematic diagram of a gas stove in a second state provided by an embodiment of the present application. Figure 3 to Figure 4 As shown, in order to solve the above problems, the ignition mechanism provided by the present application further includes a shielding member 3 and a driving assembly 4. The shielding member 3 is movably mounted on the inner ignition cover 400 relative to the ignition needle 2. The driving assembly 4 is used to drive the shielding member 3 to move as needed, so that the shielding member 3 has an ignition position located directly above the ignition needle 2 and the thermocouple 1 and an avoidance position away from the ignition needle 2 and the thermocouple 1. When ignition is required, refer to Figure 2 and Figure 4 As shown, the driving assembly 4 drives the shielding member 3 to move to the ignition position directly above the ignition needle 2 and the thermocouple 1, which can avoid the occurrence of poor ignition caused by the different ignition positions of the ignition needle 2. At the same time, the shielding member 3 can protect the thermocouple 1, prevent the ignition from leaving the flame, ensure that the thermocouple 1 can normally suck the valve, and avoid accidental flameout; when the ignition is completed, see Figure 1 and Figure 3 As shown, the driving assembly 4 drives the shielding member 3 to move to a avoiding position away from the ignition needle 2 and the thermocouple 1, so as to prevent the shielding member 3 from affecting the combustion efficiency.

[0064] In this embodiment, the shielding member 3 is movably mounted on the inner ignition cover 400 in the horizontal direction, and the shielding member 3 is located above the ignition needle 2 and the thermocouple 1. The driving assembly 4 is used to drive the shielding member 3 to move in the horizontal direction so that the shielding member 3 switches between the ignition position and the avoidance position.

[0065] In other embodiments, the shielding member 3 can also be rotatably mounted on the inner ignition cover 400 in a horizontal plane, and the shielding member 3 is located above the ignition needle 2 and the thermocouple 1. The driving assembly 4 is used to drive the shielding member 3 to rotate so that the shielding member 3 switches between the ignition position and the avoidance position. It can be understood that the movement of the shielding member 3 is not limited to the above-mentioned two forms of moving in the horizontal direction or rotating in the horizontal plane. As long as the shielding member 3 can have an ignition position directly above the ignition needle 2 and the thermocouple 1 and a avoidance position avoiding the ignition needle 2 and the thermocouple 1, all movement forms are acceptable, and no further examples will be given here.

[0066] In order to improve the effect of the shielding member 3, when the shielding member 3 is in the ignition position, the interval between the shielding member 3 and the ignition needle 2 is 3mm to 5mm, for example, it can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. This numerical range can not only ensure that the ignition needle 2 can perform high-quality ignition, but also protect the thermocouple 1, ensure that the thermocouple 1 sucks the valve normally, and avoid accidental flameout.

[0067] Figure 5 FIG. 4 is a schematic diagram showing the structure of the drive assembly 4 provided in the embodiment of the present application. Figure 5 Combination Figure 4 As shown, the drive assembly 4 includes a driver 41, a first connecting rod 42 and a second connecting rod 43. The first end of the second connecting rod 43 is hinged to the shielding member 3, and the second end thereof is hinged to the first end of the first connecting rod 42. The driver 41 is transmission-connected to the second end of the first connecting rod 42 and is used to drive the first connecting rod 42 to rise and fall in the vertical direction, so that the second connecting rod 43 pulls the shielding member 3 to switch between the ignition position and the avoidance position. For example, the driver 41 can use a servo motor, which can improve the control accuracy of the drive assembly 4 on the shielding member 3.

[0068] The driving assembly 4 also includes a meshing worm wheel 44 and a worm 45. The worm wheel 44 is connected to the output end of the driver 41, and the worm 45 is fixed to the second end of the first connecting rod 42. The driver 41 is used to drive the worm wheel 44 to rotate so that the worm 45 drives the first connecting rod 42 to rise and fall in the vertical direction.

[0069] In order to ensure the stable movement of the shielding member 3, the ignition mechanism further includes a guide member 5, which has a slide groove 51 extending in the horizontal direction, and a part of the structure of the shielding member 3 can be slidably installed in the slide groove 51. This design can limit and guide the movement trajectory of the shielding member 3 through the slide groove 51 of the guide member 5 to ensure the accuracy of the movement position of the shielding member 3.

[0070] Figure 6 Shows Figure 4 A partial schematic diagram of the middle shielding member 3. Figure 6 Combination Figure 5 As shown, the shielding member 3 includes a shielding portion 31, a sliding portion 32 and a hinged portion 33 connected in sequence, the shielding portion 31 can be located directly above the ignition needle 2, the sliding portion 32 is slidably matched with the slide groove 51, and the hinged portion 33 is located outside the slide groove 51 and is hinged to the first end of the second connecting rod 43. This design can ensure that the shielding member 3 can not only completely shield the ignition needle 2 and the thermocouple 1, but also can be slidably matched with the slide groove 51 of the guide member 5, and can also facilitate the hinge between the shielding member 3 and the second connecting rod 43.

[0071] In this embodiment, the shielding portion 31 is fan-shaped so that the shielding portion 31 can completely shield the ignition needle 2 and the thermocouple 1. The sliding portion 32 is rectangular in shape so that the sliding portion 32 can be directional and slidably matched with the slide groove 51. The hinge portion 33 is vertically connected to the sliding portion 32 so that the hinge portion 33 and the second connecting rod 43 are hingedly connected.

[0072] Furthermore, the slide groove 51 has a guide portion 511 and an opening 512 connected to the guide portion 511, and the width of the opening 512 is smaller than the width of the guide portion 511. In other words, the width of the sliding portion 32 is larger than the width of the hinge portion 33. The sliding portion 32 and the guide portion 511 are slidably matched, and the hinge portion 33 extends from the opening 512 to the outside of the slide groove 51. This design can prevent the sliding portion 32 from detaching from the guide portion 511 of the slide groove 51, thereby improving the stability of the movement of the shielding member 3.

[0073] The gas stove also includes a cap 500, which is covered on the shielding member 3. Specifically, the cap 500 is placed on the upper surface of the guide member 5, which can not only prevent debris from entering the inner fire cover 400, but also improve the appearance of the gas stove.

[0074] The upper surface of the inner fire cover 400 has a plurality of support members 403, which are arranged on the peripheral side of the guide member 5. The support members 403 are used to support the cap 500 to improve the stability of the cap 500. In this embodiment, the number of the support members 403 is four, and the four support members 403 are arranged in a rectangular shape. In other embodiments, the number of the support members 403 is not limited to four, and can also be any number such as three, five, six, seven, eight, etc., which is not limited here.

[0075] The gas stove provided in the present application also includes a battery and a controller. The battery is installed on the base 100 and is used to power the ignition needle 2; the controller is used to control the driving component 4 to drive the shielding member 3 to extend the length of the inner fire cover 400 according to the battery power to ensure that the ignition needle 2 is in the optimal ignition position and improve the ignition success rate.

[0076] In one embodiment, when the battery power is greater than or equal to the first power, the shielding member 3 extends out of the inner ignition cover 400 by a length L=10*n, where L is in mm and n is the battery power loss. The controller controls the length of the shielding member 3 extending out of the inner ignition cover 400 based on the battery power. When the battery power is reduced, the discharge pulse frequency of the ignition needle 2 is reduced, resulting in a shortened spark length, making it difficult for the spark to be transmitted to the ignition hole 401 of the inner ignition cover 400, thereby affecting ignition. Therefore, the controller controls the drive assembly 4 to drive the shielding member 3 to extend out of the inner ignition cover 400 and approach the ignition needle 2. The shielding member 3 can guide the spark emitted by the ignition needle 2 so that the spark is transmitted to the ignition hole 401 of the inner ignition cover 400, so that the ignition needle 2 is at the optimal ignition distance, thereby improving the ignition success rate.

[0077] In one embodiment, when the battery power is greater than or equal to the second power and less than the first power, the length of the shielding member 3 extending out of the inner ignition cover 400 is the maximum extension length Lmax of the shielding member 3, wherein the second power is less than the first power. When the battery power is at a lower level, the discharge pulse frequency of the ignition needle 2 may be further reduced. In order to improve the ignition success rate, the controller controls the driving component 4 to drive the shielding member 3 to extend to its maximum extension length Lmax.

[0078] In addition, the gas stove also includes an alarm, which is used to send a low-battery warning signal when the battery power is less than the second power level, so as to remind the user that the battery power is too low, so that the user can replace the battery in time.

[0079] In this embodiment, the first power is 60% and the second power is 10%. For example, when the battery power is 90%, the battery power loss is 10%. At this time, L is 10*10%, which is 1mm; when the battery power is 80%, the battery power loss is 20%. At this time, L is 10*20%, which is 2mm; when the battery power is 70%, the battery power loss is 30%. At this time, L is 10*30%, which is 3mm; when the battery power is 60%, the battery power loss is 40%. At this time, L is 10*40%, which is 4mm. In addition, the maximum extension length Lmax of the shielding member 3 is 10*40%, that is, 4mm. Of course, in other embodiments, the first power and the second power can also select other values ​​according to needs, which are not limited here.

[0080] The working principle of the ignition mechanism provided in the present application is as follows: in the initial state, the shielding member 3 is located in the avoidance position. When the ignition is turned on, the controller drives the shielding member 3 to extend out of the inner fire cover 400 according to the power drive component 4, which can achieve high-quality ignition and avoid the problem of poor ignition caused by the inconsistent ignition position of the ignition needle 2. At the same time, the shielding member 3 can protect the thermocouple 1, prevent the main fire hole 402 from leaving the flame, ensure the normal valve suction of the thermocouple 1, and avoid accidental flameout. When the ignition is completed, according to the valve suction signal of the thermocouple 1, the drive component 4 reversely drives the shielding member 3 back to between the cap 500 and the inner fire cover 400, and stops at the avoidance position avoiding the ignition needle 2 and the thermocouple 1. At this time, the shielding member 3 can be prevented from affecting the combustion of the main fire hole 402 of the inner fire cover 400, thereby improving the thermal efficiency.

[0081] Figure 7 FIG. 1 is a flow chart of a gas stove ignition control method provided in an embodiment of the present application.

[0093] In the above steps, the first power can be 60%, and the second power can be 10%; for example, when the battery power is 90%, the battery power loss is 10%, at this time, L is 10*10%, that is, 1mm; when the battery power is 80%, the battery power loss is 20%, at this time, L is 10*20%, that is, 2mm; when the battery power is 70%, the battery power loss is 30%, at this time, L is 10*30%, that is, 3mm; when the battery power is 60%, the battery power loss is 40%, at this time, L is 10*40%, that is, 4mm. The maximum extension length Lmax of the shielding member 3 = 10*40%, that is, 4mm.
