Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0055] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0056] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0057] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms may include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value, plus or minus.

[0058] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0059] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application.

[0060] Figure 1A schematic diagram of the structure of the gas stove in the first state provided in the embodiment of this application is shown. Figure 2 A schematic diagram of the structure of the gas stove in the second state according to an embodiment of this application is shown. Figures 1 to 2 As shown, the gas stove includes a base 100, a burner head 200, an outer burner cap 300, and an inner burner cap 400. The burner head 200 is mounted on the base 100. The outer burner cap 300 covers the outer ring injector tube of the burner head 200. The inner burner cap 400 covers the central injector tube of the burner head 200, and the inner burner cap 400 has an ignition hole 401 and a main burner hole 402 located above the ignition hole 401.

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

[0062] The related technology has the following risks: due to installation errors of the ignition needle 2 or accidental collisions during use, the ignition needle 2 may deviate from the optimal ignition position, resulting in poor ignition. Furthermore, flame lift-off may easily occur at the ignition hole 401, causing the thermocouple 1 to fail to sense and draw the valve normally.

[0063] Figure 3 A cross-sectional schematic diagram of the gas stove in the first state provided in the embodiment of this application is shown. Figure 4 A cross-sectional schematic diagram of the gas stove in a second state according to an embodiment of this application is shown. Figures 3 to 4 As shown, to solve the above problems, the ignition mechanism provided in this application further includes a shield 3 and a drive assembly 4. The shield 3 is movably mounted on the inner ignition cap 400 relative to the ignition needle 2. The drive assembly 4 is used to drive the shield 3 to move as needed, so that the shield 3 has an ignition position spaced directly above the ignition needle 2 and the thermocouple 1, and a clearance position avoiding the ignition needle 2 and the thermocouple 1. When ignition is required, see... Figure 2 and Figure 4 As shown, the drive assembly 4 drives the shield 3 to move to the ignition position directly above the ignition needle 2 and thermocouple 1. This prevents poor ignition caused by inconsistent ignition positions of the ignition needle 2. Simultaneously, the shield 3 protects the thermocouple 1, preventing flame lift-off and ensuring proper valve intake for the thermocouple 1, thus preventing accidental flameout. After ignition is complete, see... Figure 1 and Figure 3 As shown, the drive assembly 4 drives the shield 3 to move to a position that avoids the ignition needle 2 and the thermocouple 1, so as to prevent the shield 3 from affecting the combustion efficiency.

[0064] In this embodiment, the shielding member 3 is movably mounted on the inner flame cap 400 in a 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 a 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 flame cap 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 an ignition position and an avoidance position. It is understood that the movement of the shielding member 3 is not limited to the two types of movement described above, such as moving horizontally or rotating in a horizontal plane. Any movement that allows the shielding member 3 to have an ignition position directly above the ignition needle 2 and the thermocouple 1 and an avoidance position that avoids the ignition needle 2 and the thermocouple 1 is acceptable, and will not be described in detail here.

[0066] To improve the effectiveness of the shielding component 3, when the shielding component 3 is in the ignition position, the distance between the shielding component 3 and the ignition needle 2 is 3mm to 5mm, such as 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. This range of values ​​can ensure that the ignition needle 2 can perform high-quality ignition, and also protect the thermocouple 1, ensuring that the thermocouple 1 can draw the valve normally and avoid accidental flameout.

[0067] Figure 5 A schematic diagram of the structure of the driving component 4 provided in an embodiment of this application is shown. Figure 5 Combination Figure 4 As shown, the drive assembly 4 includes a driver 41, a first link 42, and a second link 43. The first end of the second link 43 is hinged to the blocking member 3, and its second end is hinged to the first end of the first link 42. The driver 41 is drively connected to the second end of the first link 42 and is used to drive the first link 42 to move vertically up and down, so that the second link 43 pulls the blocking member 3 between the ignition position and the avoidance position. For example, the driver 41 can be a servo motor, which can improve the control accuracy of the drive assembly 4 on the blocking member 3.

[0068] The drive assembly 4 also includes a meshing worm gear 44 and a worm 45. The worm gear 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 gear 44 to rotate so that the worm 45 drives the first connecting rod 42 to move up and down in the vertical direction.

[0069] To ensure the stable movement of the shielding component 3, the ignition mechanism also includes a guide component 5. The guide component 5 has a horizontally extending groove 51, and a portion of the shielding component 3 is slidably mounted within the groove 51. This design uses the groove 51 of the guide component 5 to limit and guide the movement trajectory of the shielding component 3, thereby ensuring the accuracy of the shielding component 3's movement position.

[0070] Figure 6 It shows Figure 4 A partial schematic diagram of the middle blocking component 3. (See attached diagram.) Figure 6 Combination Figure 5 As shown, the shielding member 3 includes a shielding part 31, a sliding part 32, and a hinge part 33 connected in sequence. The shielding part 31 can be located directly above the ignition needle 2. The sliding part 32 is slidably engaged with the slide groove 51. The hinge part 33 is located outside the slide groove 51 and is hinged to the first end of the second connecting rod 43. This design ensures that the shielding member 3 can completely shield the ignition needle 2 and the thermocouple 1, can slidely engage with the slide groove 51 of the guide member 5, and can also facilitate the hinge connection between the shielding member 3 and the second connecting rod 43.

[0071] In this embodiment, the shielding part 31 is fan-shaped so that it can completely shield the ignition needle 2 and the thermocouple 1 directly above. The sliding part 32 is rectangular so that it can slide and engage with the groove 51 in a directional manner. The hinge part 33 is perpendicularly connected to the sliding part 32 so that it can be hinged to the second connecting rod 43.

[0072] Furthermore, the slide groove 51 has a guide portion 511 and an opening 512 communicating with 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 greater than the width of the hinge portion 33. The sliding portion 32 slides in conjunction with the guide portion 511, and the hinge portion 33 extends out of the slide groove 51 from the opening 512. This design can prevent the sliding portion 32 from disengaging from the guide portion 511 of the slide groove 51, thereby improving the stability of the movement of the blocking member 3.

[0073] The gas stove also includes a cap 500, which is placed on top of the shield 3. Specifically, the cap 500 is placed on the upper surface of the guide 5, which not only prevents debris from entering the inner burner cover 400, but also enhances the appearance of the gas stove.

[0074] The upper surface of the inner flame cap 400 has several support members 403, which are arranged around the periphery 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, there are four support members 403, which are arranged in a rectangular shape. In other embodiments, the number of support members 403 is not limited to four, but can be any number such as three, five, six, seven, or eight, which is not limited here.

[0075] The gas stove provided in this application also includes a battery and a controller. The battery is installed in the base 100 and is used to power the ignition needle 2. The controller is used to control the length of the drive assembly 4 to drive the shield 3 to extend out of the inner burner cover 400 according to the battery power, so as 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 charge is greater than or equal to a first charge level, the length L of the shielding member 3 extending out of the inner burner cap 400 is 10*n, where L is in mm and n is the battery charge loss. The controller controls the length of the shielding member 3 extending out of the inner burner cap 400 based on the battery charge level. When the battery charge decreases, the discharge pulse frequency of the ignition needle 2 decreases, resulting in a shorter spark length, making it difficult for the spark to be transmitted to the ignition hole 401 of the inner burner cap 400, thus affecting ignition. Therefore, the controller controls the drive assembly 4 to drive the shielding member 3 to extend out of the inner burner cap 400 and approach the ignition needle 2. The shielding member 3 can guide the spark emitted by the ignition needle 2 to be transmitted to the ignition hole 401 of the inner burner cap 400, thereby placing the ignition needle 2 at the optimal ignition distance and improving the ignition success rate.

[0077] In one embodiment, when the battery charge is greater than or equal to a second charge level and less than a first charge level, the length by which the shield 3 extends beyond the inner ignition cap 400 is the maximum extension length Lmax of the shield 3, wherein the second charge level is less than the first charge level. When the battery charge is at a low level, the discharge pulse frequency of the ignition needle 2 may further decrease. To improve the ignition success rate, the controller controls the drive assembly 4 to drive the shield 3 to extend to its maximum extension length Lmax.

[0078] In addition, the gas stove also includes an alarm, which is used to issue a low battery warning signal when the battery power is less than the second charge level, so as to remind the user that the battery power is too low and make it easier for the user to replace the battery in time.

[0079] In this embodiment, the first charge level is 60%, and the second charge level is 10%. For example, when the battery charge level is 90%, the battery charge loss is 10%, and L is 10 * 10%, which is 1mm; when the battery charge level is 80%, the battery charge loss is 20%, and L is 10 * 20%, which is 2mm; when the battery charge level is 70%, the battery charge loss is 30%, and L is 10 * 30%, which is 3mm; when the battery charge level is 60%, the battery charge loss is 40%, and L is 10 * 40%, which is 4mm. Furthermore, the maximum extension length Lmax of the shielding member 3 is 10 * 40%, which is 4mm. Of course, in other embodiments, the first and second charge levels can be selected as other values ​​as needed, and this is not limited here.

[0080] The working principle of the ignition mechanism provided in this application is as follows: In the initial state, the blocking member 3 is in a clearance position. When ignition is started, the controller drives the blocking member 3 to extend outside the inner flame cap 400 according to the power driving component 4, which can achieve high-quality ignition and avoid ignition problems caused by inconsistent ignition positions of the ignition needle 2. At the same time, the blocking member 3 can protect the thermocouple 1, prevent the main flame hole 402 from leaving the flame, ensure the normal valve intake of the thermocouple 1, and avoid accidental flameout. After ignition is completed, according to the valve intake signal of the thermocouple 1, the driving component 4 drives the blocking member 3 in the reverse direction to retract between the cap 500 and the inner flame cap 400, and stops at the clearance position that avoids the ignition needle 2 and the thermocouple 1. At this time, the blocking member 3 can avoid affecting the combustion of the main flame hole 402 of the inner flame cap 400, thus improving thermal efficiency.

[0081] Figure 7 A flowchart illustrating the gas stove ignition control method provided in an embodiment of this application is shown. Figure 7 Combination Figures 1 to 6 As shown, based on the above-mentioned gas stove, this application also provides a gas stove ignition control method, including the following steps:

[0082] S1, Ignition needle 2 initiates discharge.

[0083] S2. Determine if the gas stove has been successfully ignited; if yes, start cooking until cooking is finished; if not, proceed to S3.

[0084] S3. Determine if the battery level is greater than or equal to the first charge level. If yes, proceed to S4; otherwise, proceed to S5.

[0085] S4, drive component 4 drives shield 3 to extend the inner fire cover 400 by a length L = 10 * n; where n is the battery power loss, then execute S7.

[0086] S5. Determine if the battery level is lower than the second battery level; where the second battery level is lower than the first battery level; if yes, remind the user to replace the battery; if no, proceed to S6.

[0087] S6, drive component 4 to extend the shield 3 to the maximum extension length Lmax; then execute S7.

[0088] S7, Ignition needle 2 restarts ignition, then executes S8.

[0089] S8. Determine if the gas stove has been successfully ignited; if so, retract the shield 3 and start cooking until cooking is finished; if not, execute S9.

[0090] S9. Determine whether the extension length of the blocking component 3 is its maximum extension length Lmax; if yes, execute S10; if no, execute S11.

[0091] S10, reminding the user of an ignition malfunction.

[0092] S11, drive component 4 drives shield 3 to extend to its maximum extension length Lmax; then re-execute S8.

[0093] In the above steps, the first charge level can be 60%, and the second charge level can be 10%. For example, when the battery charge is 90%, the battery charge loss is 10%, and L is 10 * 10%, which is 1mm; when the battery charge is 80%, the battery charge loss is 20%, and L is 10 * 20%, which is 2mm; when the battery charge is 70%, the battery charge loss is 30%, and L is 10 * 30%, which is 3mm; when the battery charge is 60%, the battery charge loss is 40%, and L is 10 * 40%, which is 4mm. The maximum extension length of the shield 3, Lmax, is 10 * 40%, which is 4mm.

Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
