In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0040] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the term "installation", "connection" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, can be mechanical connection, also can be electrical connection, can be direct connection, also can be indirect connection through intermediate medium, can be the intercommunication of two elements interiorly.For the ordinary skill in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to the specific circumstances.

[0041] As Figures 1 to 4 Indicated, the utility model provides a kind of ignition device, can protect ignition needle 1, prolong the service life of ignition needle 1.The ignition device includes ignition needle 1 and drive mechanism 2.

[0042] Wherein, ignition needle 1 is movably arranged in the burner of range 200 along first direction, and ignition needle 1 has ignition position and storage position.Drive mechanism 2 includes moving seat 21 movably arranged in the bottom shell 100 of range along second direction, and moving seat 21 is provided with obliquely extended push surface 211, and when moving seat 21 moves along second direction, push surface 211 can contact with ignition needle 1 and drive ignition needle 1 to move along first direction towards ignition position or storage position, and second direction is perpendicular or approximately perpendicular to first direction.

[0043] In the embodiment, refer to the orientation in Figure 2 And Figure 4 First direction is vertical direction, and second direction is front-back direction.In other embodiments, second direction can also be left-right direction in Figure 4 .

[0044] Approximately perpendicular here refers to that the included angle between first direction and second direction is approximately 90 °, for example, the included angle between them is 85 °-95 °, can be 86 °, 89 °, 91 °, 93 ° etc.

[0045] The ignition device provided by the embodiment, as shown in Figure 2 And Figure 3 When driving moving seat 21 to move positively or negatively along second direction, push surface 211 is slidably connected with ignition needle 1, and since push surface 211 is obliquely arranged, when moving seat 21 moves to different positions along second direction, ignition needle 1 contacts with different positions of push surface 211, and the height of ignition needle 1 lifted by push surface 211 is different, so as to change the position of ignition needle 1.

[0046] Specifically, when ignition is needed, the moving seat 21 can be driven to move in the second direction positively until the ignition needle 1 rises to the ignition position, the ignition needle 1 strikes fire to ignite the gas output by the fire hole of the fire cap 300. After the ignition is completed, the moving seat 21 is driven to move in the second direction negatively until the ignition needle 1 falls to the storage position. In this way, the ignition needle 1 can be avoided to be always in the burning flame, the time of the ignition needle 1 being burned is reduced, and the service life of the ignition needle 1 is prolonged. Meanwhile, the ignition leakage phenomenon can be avoided, and the phenomenon of the ignition needle 1 contacting the yellow flame due to burning can be avoided, the harmful gas generation is reduced, and the use safety of the cooktop is improved. When the cooktop is cleaned, the ignition needle 1 can be switched to the storage position by the moving seat 21, the ignition needle 1 is avoided to protrude to hinder the cleaning, and the ignition needle 1 can be prevented from being damaged by collision in the cleaning process. In addition, in the transportation process of the cooktop, the ignition needle 1 can be switched to the storage position by the moving seat 21, the packaging difficulty can be reduced, and the ignition needle 1 can be prevented from being damaged by collision in the transportation process.

[0047] That is, the ignition device switches the ignition needle 1 between the ignition position and the storage position, so that the ignition needle 1 can be stored when not in use, which not only does not affect the normal use of the ignition needle 1, but also protects the ignition needle 1 and prolongs the service life of the ignition needle 1.

[0048] As shown in Figure 1 , the cooktop comprises a bottom shell 100 and a panel (not shown in the figure) arranged on the bottom shell 100, and the burner 200 is fixed to the bottom shell 100. When in the storage position, the top end of the ignition needle 1 does not protrude from the top surface of the panel. That is, when in the storage position, the ignition needle 1 can be hidden below the panel, the top surface of the panel is ensured to be flat, and the ignition needle 1 is avoided to protrude to hinder the cleaning operation. The ignition needle 1 can be prevented from scratching the user when the panel is cleaned, and the cleaning dead angle can be eliminated.

[0049] Of course, in other embodiments, the ignition needle 1 can only be kept at a certain distance from the fire cap 300 when in the storage position, and the ignition needle 1 can be ensured to avoid the burning flame, without needing to hide the ignition needle 1 below the panel.

[0050] Optionally, referring to Figure 2 and Figure 3 , the moving seat 21 is concavely provided with a limiting groove 212, the groove wall surface of the limiting groove 212 is the abutting surface 211, and the end portion of the ignition needle 1 is at least partially located in the limiting groove 212 and is in sliding cooperation with the limiting groove 212. The limiting groove 212 is provided to limit the relative movement of the ignition needle 1 to the moving seat 21 in the direction in which the limiting groove 212 extends, to prevent the ignition needle 1 from being separated from the moving seat 21, and to improve the stability of the moving seat 21 in driving the ignition needle 1 to move up and down.

[0051] Referring to Figure 2 and Figure 3The end of the ignition needle 1 close to the moving seat 21 is provided with a contact part 11, the contact part 11 is provided with an outer convex arc surface 111, and the outer convex arc surface 111 is in sliding fit with the pushing surface 211. The outer convex arc surface 111 can reduce the sliding resistance of the ignition needle 1 relative to the pushing surface 211, and improve the smoothness of the lifting movement of the ignition needle 1. Exemplarily, the contact part 11 is a ball head structure arranged at the end of the ignition needle 1, and the spherical surface of the ball head structure is the outer convex arc surface 111.

[0052] In an optional embodiment, as shown in Figure 3 and Figure 4 , the pushing surface 211 is an inner concave arc surface arranged on the moving seat 21, and the extension direction of the inner concave arc surface is inclined relative to the panel of the cooker. In this embodiment, the slot wall of the limiting slot 212 is designed as an arc-shaped slot wall, which is the inner concave arc surface, and the ignition needle 1 is in sliding fit with the inner concave arc surface, which can reduce the sliding resistance of the ignition needle 1 and improve the moving efficiency of the ignition needle 1.

[0053] In another optional embodiment, the pushing surface 211 can also be a pushing plane arranged on the moving seat 21, and the extension direction of the pushing plane is inclined relative to the panel of the cooker. That is, the pushing surface 211 is an inclined plane, and when the moving seat 21 moves in the second direction, the ignition needle 1 moves along the inclined pushing plane. As the ignition needle 1 contacts the pushing plane at different positions, the height of the ignition needle 1 lifted by the pushing plane is different, thereby adjusting the height of the ignition needle 1, moving the ignition needle 1 to the ignition position, or retracting the ignition needle 1 to the storage position.

[0054] Exemplarily, the moving seat 21 is a trapezoidal block structure or a triangular block structure, and the inclined edge of the moving seat 21 faces the ignition needle 1. When the limiting slot 212 is arranged on the moving seat 21, the limiting slot 212 is opened on the inclined edge of the moving seat 21, and the bottom wall of the limiting slot 212 is designed as a plane, which is the pushing plane. When the moving seat 21 is not provided with the limiting slot 212, the plane where the inclined edge of the moving seat 21 faces the ignition needle 1 is the pushing plane.

[0055] Optionally, referring to Figure 2 , Figure 3 and Figure 4 , the driving mechanism 2 further comprises a driving member 22, and the output end of the driving member 22 is connected with the moving seat 21, for driving the moving seat 21 to move in the second direction. The arrangement of the driving member 22 can realize electric control of the movement of the moving seat 21, and improve the degree of automation.

[0056] In this embodiment, the output end of the driving member 22 is rotationally provided with a gear 221, and the moving seat 21 is provided with a rack 213 extending along the second direction, and the gear 221 is in meshing transmission with the rack 213. When the driving member 22 drives the gear 221 to rotate, the gear teeth of the gear 221 push the teeth on the rack 213 to apply a pushing force, thereby driving the rack 213 to move the moving seat 21 along the second direction. The cooperation between the gear 221 and the rack 213 can accurately control the moving distance of the moving seat 21, and further accurately control the lifting height of the ignition needle 1, so that the ignition needle 1 can accurately switch between the ignition position and the storage position.

[0057] For example, the output end of the driving member 22 is a rotatable output shaft 222, and the gear 221 is fixedly connected with the output shaft 222. For example, the driving member 22 can be a rotary motor, and the housing of the rotary motor is fixed to the bottom shell 100 of the stove.

[0058] In other embodiments, the output end of the driving member 22 can be a telescopic rod which can be telescoped along the second direction, and the telescopic rod is fixedly connected with the moving seat 21. That is, the driving member 22 is a linear driving structure, and can directly drive the moving seat 21 to move linearly along the second direction. For example, the driving member 22 can be a pneumatic cylinder or an electric cylinder, and the output rod of the pneumatic cylinder or the electric cylinder is the telescopic rod mentioned above.

[0059] Optionally, referring to Figure 2 and Figure 3 , the moving seat 21 is provided with a mounting space 214, and the rack 213 and the gear 221 are located in the mounting space 214. The mounting space 214 can reduce the space occupied by the driving member 22 and the moving seat 21 after assembly, which is beneficial to the rational use of the space in the bottom shell 100 of the stove.

[0060] Further, the mounting space 214 is a through groove formed on the moving seat 21, and the two ends of the through groove in the second direction are in a closed state, which can limit the moving stroke of the gear 221 in the second direction, and avoid the overstroke of the moving seat 21 in the second direction.

[0061] For example, the bottom wall of the through groove is spaced apart along the second direction and provided with a plurality of teeth, and the plurality of teeth form the rack 213 mentioned above. In other embodiments, a separately processed rack 213 can also be fixed on the groove wall of the through groove.

[0062] In some embodiments, the driving member 22 can also be arranged on one side of the moving seat 21, and the rack 213 can be arranged on the side of the moving seat 21 facing the driving member 22, and the gear 221 is in meshing transmission with the rack 213. In this way, the driving member 22 can also drive the moving seat 21 to move by pushing the rack 213 through the gear 221, thereby driving the ignition needle 1 to switch between the ignition position and the storage position.

[0063] Optionally, referring toFigure 4 The mobile seat 21 is provided with a limiting part 215 at at least one end of the pushing surface 211, and the limiting part 215 is used to limit the moving stroke of the ignition needle 1 relative to the pushing surface 211 in the second direction. The limiting part 215 can prevent the ignition needle 1 from being separated from the mobile seat 21, and ensure the stable cooperation between the mobile seat 21 and the ignition needle 1.

[0064] In this embodiment, the top end of the pushing surface 211 is provided with a limiting part 215. When the ignition needle 1 slides relative to the pushing surface 211 to abut against the limiting part 215, the ignition needle 1 cannot continue to move, thereby avoiding the ignition needle 1 from being separated from the mobile seat 21. Exemplarily, the limiting part 215 is a limiting surface provided at the end of the limiting groove 212. Alternatively, when the mobile seat 21 is not provided with the limiting groove 212, the limiting part 215 can be a limiting protrusion protruding on the pushing surface 211.

[0065] In other embodiments, the limiting part 215 can also be provided at the lower end of the pushing surface 211 to prevent the ignition needle 1 from being separated from the mobile seat 21 when switching to the storage position.

[0066] Referring to Figure 3 The ignition needle 1 is movably arranged on the burner head 200 of the stove in the first direction, and the burner head 200 is provided with a guide seat 201, and the guide seat 201 is provided with a guide hole 2011 extending in the first direction, and the ignition needle 1 movably penetrates the guide hole 2011. The guide hole 2011 can limit the moving direction of the ignition needle 1, prevent the ignition needle 1 from moving off track, and ensure that the ignition needle 1 can be aligned with the fire hole of the fire cap 300 when moving to the ignition position, thereby ensuring the success rate of ignition. Exemplarily, the guide seat 201 is a protrusion integrally formed on the burner head 200.

[0067] Alternatively, the outer diameter of the ignition needle 1 gradually decreases in the direction close to the ignition end thereof, and the outer diameter of the large-diameter end of the ignition needle 1 is larger than the size of the guide hole 2011. When the mobile seat 21 drives the ignition needle 1 to move upward, the ignition needle 1 will not be separated from the guide hole 2011, so as to limit the maximum stroke of the upward movement of the ignition needle 1.

[0068] Alternatively, the bottom shell 100 of the stove is provided with a sliding groove or sliding rail extending in the second direction, and the mobile seat 21 is slidably connected to the sliding groove or sliding rail. The mobile seat 21 is slidably connected in the bottom shell 100 of the stove, which can limit the mobile seat 21 to always move in the second direction, ensure the moving accuracy of the mobile seat 21, and improve the stability of the ignition needle 1 moving in the first direction.
