Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an ignition device and a gas stove. Background Technology
[0002] Most household gas stoves use an ignition needle pulse discharge method to ignite the gas. The ignition needle is usually located near the burner outlet of the gas stove. During ignition, the discharge end of the ignition needle generates a high voltage, which breaks down the air between the needle and the burner cap to form an electric arc, thereby igniting the gas ejected from the burner outlet and achieving gas stove ignition.
[0003] The ignition needle on existing gas stoves is usually fixed to the burner head and protrudes from the stovetop. After ignition, the ignition needle remains in a burning state, which can easily cause the insulation of the wire at the end of the needle to melt, exposing the internal metal wire and leading to ignition leakage, posing a safety hazard. Furthermore, when cleaning the stovetop, because the ignition needle protrudes from the surface, it is easily bumped when removing or placing the burner cap, causing it to break.
[0004] Therefore, there is an urgent need for an ignition device and gas stove to solve the above problems. Utility Model Content
[0005] Based on the above problems, the purpose of this utility model is to provide an ignition device and a gas stove that can prevent the ignition needle from being in a burning state for a long time and extend the service life of the ignition needle.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] On the one hand, an ignition device is provided, comprising:
[0008] The ignition needle is movable and located on the burner of the gas stove, and has both an ignition position and a storage position.
[0009] The driving mechanism includes a driving component and a swing structure that is oscillatingly disposed on the bottom shell of the gas stove. The first end of the swing structure is movably connected to the output end of the driving component, and the second end of the swing structure is movably connected to the ignition needle. The rotation axis of the swing structure is located between the first end and the second end.
[0010] The driving component can drive the first end of the swing structure to rotate around the rotation axis, so that the second end of the swing structure drives the ignition needle to switch between the ignition position and the storage position.
[0011] As an optional embodiment of the ignition device of this utility model, the swing structure includes a first swing member and a second swing member arranged at an angle, and the second swing member is bent relative to the first swing member toward the side closer to the ignition needle. The first swing member is movably connected to the output end of the driving member, and the second swing member is movably connected to the ignition needle.
[0012] As an optional solution for the ignition device of this utility model, a rotating seat is provided at the connection between the first swing member and the second swing member. The rotating seat is provided with a shaft hole. A rotating shaft is provided on the housing of the driving member or the bottom shell of the gas stove. The rotating shaft is inserted into the shaft hole and rotates with the shaft hole. The axis of the shaft hole is the axis of rotation.
[0013] As an optional embodiment of the ignition device of this utility model, the first swing member is provided with a movable groove, and the output end of the driving member is provided with an eccentric shaft. The eccentric shaft is located in the movable groove. The groove wall of the movable groove includes a first contact wall and a second contact wall arranged opposite to each other. The eccentric shaft has an eccentric protrusion. When the driving member drives the eccentric shaft to rotate, the eccentric protrusion can selectively contact either the first contact wall or the second contact wall. When the eccentric protrusion contacts the first contact wall, the second swing member drives the ignition needle to move to the ignition position. When the eccentric protrusion contacts the second contact wall, the second swing member drives the ignition needle to move to the storage position.
[0014] Alternatively, the output end of the drive component is a telescopic rod, which is slidably connected to the first swing component.
[0015] As an optional embodiment of the ignition device of this utility model, the first swing member includes a first plate segment, a second plate segment, and a third plate segment that are bent and connected in sequence. The first plate segment, the second plate segment, and the third plate segment form the movable groove. The first plate segment is opposite to the third plate segment. The side of the first plate segment facing the third plate segment is the first contact wall, and the side of the third plate segment facing the first plate segment is the second contact wall.
[0016] As an optional embodiment of the ignition device of this utility model, the second swing member includes a main body and a connecting part that are connected and arranged at an angle. The end of the main body away from the connecting part is fixedly connected to the first swing member, and the connecting part is movably connected to the ignition needle. When the ignition needle is in the ignition position, the connecting part is perpendicular or approximately perpendicular to the ignition needle.
[0017] As an optional solution for the ignition device of this utility model, the ignition needle is provided with a first limiting part and a second limiting part at intervals along the axial direction, the second end of the swing structure is provided with a connecting hole, the ignition needle is movably passed through the connecting hole, and the first limiting part and the second limiting part are provided on both sides of the connecting hole along the axial direction.
[0018] Alternatively, the second end of the swing structure is rotatably connected to the ignition needle.
[0019] As an optional solution for the ignition device of this utility model, the gas stove includes a bottom shell and a panel covering the bottom shell, the burner head is fixed to the bottom shell, and in the storage position, the tip of the ignition needle does not protrude from the top surface of the panel.
[0020] As an optional solution for the ignition device of this utility model, a guide seat is provided on the burner head, and a guide hole extending in the vertical direction is provided on the guide seat, and the ignition needle is movably inserted through the guide hole.
[0021] On the other hand, a gas stove is provided, including a bottom shell, a burner head, a burner cap, and an ignition device as described above, wherein the burner head and the drive mechanism of the ignition device are both disposed in the bottom shell, and the burner cap is located on the burner head.
[0022] The beneficial effects of this utility model are as follows:
[0023] The ignition device and gas stove provided by this utility model, when ignition is required, drive the first end of the swing structure to rotate around the rotation axis of the swing structure via a driving component, causing the second end of the swing structure to move the ignition needle to the ignition position. The ignition needle ignites, thus igniting the gas output from the burner holes of the burner cap. After ignition, drive the first end of the swing structure to rotate in the opposite direction, causing the second end of the swing structure to move the ignition needle to the storage position. The ignition needle can then avoid the burner cap, thus preventing the ignition needle from always being within the combustion flame, reducing the burning time of the ignition needle, and extending its service life. At the same time, it can prevent ignition leakage and the phenomenon of contact with the yellow flame due to the burning of the ignition needle, reducing the production of harmful gases and improving the safety of the gas stove. When cleaning the stove, the driving component can also drive the swing structure to switch the ignition needle to the storage position, preventing the ignition needle from being damaged by collision or scratching the user during cleaning. In addition, during the transportation of the stove, the ignition needle can be switched to the storage position by the drive component, so that the ignition needle can be hidden, which can reduce the difficulty of packaging and prevent the ignition needle from being damaged by collision during transportation.

[0044] like Figures 1 to 5 As shown, this embodiment provides an ignition device that can prevent the ignition needle 1 from being in a burning state for a long time, thus extending the service life of the ignition needle 1. The ignition device includes an ignition needle 1 and a drive mechanism 2.
[0045] Among them, see Figure 2 and Figure 3The ignition needle 1 is movably mounted on the burner head 200 of the gas stove and has an ignition position and a storage position. The drive mechanism 2 includes a drive member 21 and a swing structure 22 oscillatingly mounted on the bottom shell 100 of the gas stove. The first end of the swing structure 22 is movably connected to the output end of the drive member 21, and the second end of the swing structure 22 is movably connected to the ignition needle 1. The rotation axis of the swing structure 22 is located between the first end and the second end. The drive member 21 can drive the first end of the swing structure 22 to rotate around the rotation axis, so that the second end of the swing structure 22 drives the ignition needle 1 to switch between the ignition position and the storage position.
[0046] Reference Figure 2 In terms of orientation, the left end of the swing structure 22 is the first end mentioned above, and the right end of the swing structure 22 is the second end mentioned above.
[0047] The ignition device provided in this embodiment, when ignition is required, drives the first end of the swing structure 22 to rotate around the rotation axis of the swing structure 22 via the driving member 21, causing the second end of the swing structure 22 to move the ignition needle 1 to the ignition position (e.g., Figure 2 (As shown), the ignition needle 1 ignites the gas output from the burner hole of the burner cap 300. After ignition, the driving component 21 drives the first end of the swing structure 22 to rotate in the opposite direction, causing the second end of the swing structure 22 to move the ignition needle 1 to the retracted position (as shown). Figure 3 As shown, the ignition needle 1 can avoid the burner cap 300, thus preventing the ignition needle 1 from always being inside the combustion flame, reducing the burning time of the ignition needle 1, and extending the service life of the ignition needle 1. At the same time, it can avoid ignition leakage and the phenomenon of contact with the yellow flame due to the burning of the ignition needle 1, reduce the production of harmful gases, and improve the safety of gas stove use.
[0048] When cleaning the stovetop, the ignition needle 1 can be switched to the storage position by driving the swing structure 22 through the drive component 21, preventing the ignition needle 1 from being damaged by collision or scratching the user during cleaning. In addition, during the transportation of the stove, the ignition needle 1 can be switched to the storage position by driving the drive component 21, so that the ignition needle 1 is hidden, which can reduce the difficulty of packaging and prevent the ignition needle 1 from being damaged by collision during transportation.
[0049] like Figure 1 As shown, the gas stove includes a base shell 100 and a panel (not shown) covering the base shell 100. The burner head 200 is fixed to the base shell 100. When stored, the tip of the ignition needle 1 does not protrude from the top surface of the panel. That is, the ignition needle 1 can be hidden under the panel, ensuring that the top of the panel is flat and preventing the ignition needle 1 from protruding and obstructing cleaning operations. This not only prevents the ignition needle 1 from scratching the user when cleaning the panel, but also eliminates cleaning dead corners.
[0050] Of course, in other embodiments, the ignition needle 1 can be positioned in the storage position with only a certain distance from the burner cap 300 to ensure that the ignition needle 1 avoids the burning flame, without having to hide the ignition needle 1 under the panel.
[0051] Optionally, see Figure 2 and Figure 5 The burner head 200 is provided with a guide seat 201, and the guide seat 201 is provided with a guide hole 2011 extending vertically. The ignition needle 1 is movably inserted through the guide hole 2011. That is, the ignition needle 1 moves and switches between the ignition position and the storage position in the vertical direction. The guide hole 2011 can restrict the movement direction of the ignition needle 1, prevent the ignition needle 1 from moving off-center, and ensure that the ignition needle 1 is aligned with the flame hole of the burner cap 300 when it moves to the ignition position, thus ensuring the success rate of ignition. For example, the guide seat 201 is a protrusion integrally formed on the burner head 200.
[0052] Optionally, see Figure 2 and Figure 3 The swing structure 22 includes a first swing member 221 and a second swing member 222 arranged at an angle, with the second swing member 222 bent relative to the first swing member 221 towards the side closer to the ignition needle 1. The first swing member 221 is movably connected to the output end of the drive member 21, and the second swing member 222 is movably connected to the ignition needle 1. Designing the second swing member 222 closer to the ignition needle 1 can shorten the swing stroke of the second swing member 222 and improve the efficiency of the ignition needle 1 switching between the ignition position and the storage position.
[0053] like Figure 2 As shown, the first swing member 221 and the second swing member 222 are set at an obtuse angle. When the ignition needle 1 is in the ignition position, the first swing member 221 is arranged horizontally.
[0054] See Figure 2 , Figure 3 and Figure 4A rotating seat 223 is provided at the connection between the first swing member 221 and the second swing member 222. The rotating seat 223 is provided with a shaft hole 2231. A rotating shaft 23 is provided on the housing of the driving member 21 or the bottom shell 100 of the gas stove. The rotating shaft 23 is inserted into the shaft hole 2231 and rotates in cooperation with the shaft hole 2231. The axis of the shaft hole 2231 is the axis of rotation. That is, the end of the first swing member 221 away from the rotating seat 223 and the end of the second swing member 222 away from the rotating seat 223 are both free ends. The position of the rotating seat 223 is the rotation point. When the driving member 21 drives the first swing member 221 to swing up and down around the rotating shaft 23, the second swing member 222 swings up and down around the rotating shaft 23 simultaneously, and drives the ignition needle 1 to move up and down, so that the ignition needle 1 switches between the ignition position and the storage position. The setting of the rotating seat 223 allows the entire swing structure 22 to rotate around the rotating shaft 23, improving the swing stability of the swing structure 22.
[0055] In this embodiment, the rotating seat 223 is a bushing structure integrally formed at the connection between the first swing member 221 and the second swing member 222. It is easy to process and can save materials. The aforementioned rotating shaft 23 is provided on the housing of the driving member 21. The rotating shaft 23 is spaced apart from the output end of the driving member 21. The bushing structure is sleeved on the outside of the rotating shaft 23 and rotates in cooperation with the rotating shaft 23 to realize the rotation of the swing structure 22.
[0056] In other embodiments, the rotating seat 223 can also be designed as a block structure, and a shaft hole 2231 can be opened on the rotating seat 223. A support seat is separately provided inside the bottom shell 100 of the gas stove, the rotating shaft 23 is fixedly installed on the support seat, and the rotating seat 223 is rotatably connected to the rotating shaft 23 through the shaft hole 2231.
[0057] Optionally, see Figure 2 , Figure 3 and Figure 4 The first swing member 221 is provided with a movable groove 2210, and the output end of the drive member 21 is provided with an eccentric shaft 211. The eccentric shaft 211 is located in the movable groove 2210. The groove wall of the movable groove 2210 includes a first contact wall 22111 and a second contact wall 22131 arranged opposite to each other. The eccentric shaft 211 has an eccentric protrusion 2111. When the drive member 21 drives the eccentric shaft 211 to rotate, the eccentric protrusion 2111 can selectively contact either the first contact wall 22111 or the second contact wall 22131. When the eccentric protrusion 2111 contacts the first contact wall 22111, the second swing member 222 drives the ignition needle 1 to move to the ignition position. When the eccentric protrusion 2111 contacts the second contact wall 22131, the second swing member 222 drives the ignition needle 1 to move to the storage position.
[0058] Specifically, during the rotation of the eccentric shaft 211 driven by the driving component 21, the eccentric protrusion 2111 of the eccentric shaft 211 alternately contacts the first contact wall 22111 and the second contact wall 22131, such as... Figure 2 and Figure 4 As shown, when the eccentric shaft 211 rotates to the point where the eccentric protrusion 2111 contacts the first contact wall 22111, the first swing member 221 is pressed down by the eccentric protrusion 2111, causing the second swing member 222 to tilt upwards, and the ignition needle 1 is in the ignition position. Figure 3 As shown, when the eccentric shaft 211 rotates to the point where the eccentric protrusion 2111 contacts the second contact wall 22131, the first swing member 221 is lifted by the eccentric protrusion 2111, causing the second swing member 222 to press downwards, and the ignition needle 1 is in the retracted position. That is, the eccentric movement of the eccentric shaft 211 drives the first swing member 221 to swing up and down around the rotating shaft 23, so that the second swing member 222 can swing up and down around the rotating shaft 23 synchronously, thereby driving the ignition needle 1 to move up and down. For example, the driving member 21 is a rotary motor, and the eccentric shaft 211 is fixedly connected to the output shaft of the rotary motor.
[0059] In other alternative embodiments, the output end of the drive member 21 can also be a telescopic rod, which is slidably connected to the first swing member 221. It is understood that the telescopic rod is slidably connected to the first swing member 221 in the inclined direction of the first swing member 221. When the telescopic rod extends or retracts, it adapts to sliding relative to the first swing member 221, causing the first swing member 221 to rotate around the pivot 23, thus causing the first swing member 221 to swing up and down. Simultaneously, the first swing member 221 drives the second swing member 222 to swing up and down, thereby moving the ignition needle 1 up and down. Exemplarily, the drive member 21 can be a cylinder or a push rod motor, etc.
[0060] Optionally, see Figure 4 The first swing member 221 includes a first plate segment 2211, a second plate segment 2212, and a third plate segment 2213 that are bent and connected in sequence. A movable groove 2210 is formed between the first plate segment 2211, the second plate segment 2212, and the third plate segment 2213. The first plate segment 2211 and the third plate segment 2213 are opposite each other. The side of the first plate segment 2211 facing the third plate segment 2213 is the first contact wall 22111, and the side of the third plate segment 2213 facing the first plate segment 2211 is the second contact wall 22131. In this embodiment, the first plate segment 2211, the second plate segment 2212, and the third plate segment 2213 form a U-shaped structure. The hollow part of this U-shaped structure is the aforementioned movable groove 2210. The structural design is simple; the first swing member 221 can be integrally bent from a strip plate, making processing convenient.
[0061] In other embodiments, the first swing member 221 may also be a solid block structure, on which the aforementioned movable groove 2210 is formed, so that the eccentric shaft 211 extends into the movable groove 2210 and rotates with the movable groove 2210.
[0062] Optionally, see Figure 2 and Figure 5 The second swing member 222 includes a main body 2221 and a connecting part 2222 connected at an angle. The end of the main body 2221 away from the connecting part 2222 is fixedly connected to the first swing member 221. The connecting part 2222 is movably connected to the ignition needle 1. When the ignition needle 1 is in the ignition position, the connecting part 2222 is perpendicular or approximately perpendicular to the ignition needle 1. That is, the connecting part 2222 is bent at a certain angle relative to the main body 2221, so that after the second end of the second swing member 222 drives the ignition needle 1 to switch to the ignition position, the connecting part 2222 can support the ignition needle 1 approximately horizontally, so that the ignition needle 1 is stably maintained in the ignition position, ensuring the ignition success rate of the ignition needle 1.
[0063] It is understandable that "approximately perpendicular" here means that the angle between the ignition needle 1 and the connecting part 2222 is approximately 90°, for example, the angle between the two is 85° to 95°, to ensure that the connecting part 2222 can stably support the ignition needle 1 and will not interfere with the relative rotation of the second swing member 222 and the ignition needle 1.
[0064] For example, the second swing member 222 is integrally formed with the first swing member 221, and the connection is reliable. Further, the second swing member 222 is a strip-shaped plate structure, and the connecting part 2222 is integrally bent with the main body part 2221.
[0065] In this embodiment, the main body 2221 and the connecting part 2222 are set at an obtuse angle, such as... Figure 2 As shown, when the ignition needle 1 is in the ignition position, the connecting part 2222 is approximately horizontal, as... Figure 3 As shown, when the ignition needle 1 is in the retracted position, the main body 2221 is roughly in a horizontal position.
[0066] Optionally, see Figure 2 and Figure 5The ignition needle 1 is provided with a first limiting part 11 and a second limiting part 12 spaced apart along the axial direction. The second end of the swing structure 22 is provided with a connecting hole 2220. The ignition needle 1 is movably inserted through the connecting hole 2220, and the first limiting part 11 and the second limiting part 12 are respectively provided on both sides of the connecting hole 2220 along the axial direction. When the driving member 21 drives the first end of the swing structure 22 to swing, the second end of the swing structure 22 can move relative to the ignition needle 1 in the area between the first limiting part 11 and the second limiting part 12, so that the ignition needle 1 adapts to the rotation of the swing structure 22. At the same time, the first limiting part 11 and the second limiting part 12 can prevent the ignition needle 1 from disengaging from the connecting hole 2220, ensuring the connection stability between the linkage arm and the ignition needle 1.
[0067] See Figure 5 An annular groove 13 is recessed along the circumferential direction on the outer peripheral surface of the ignition needle 1 to form two shoulders spaced apart vertically on the ignition needle 1. These two shoulders are the first limiting part 11 and the second limiting part 12. In other embodiments, the first limiting part 11 and the second limiting part 12 may also be an annular protrusion or the like protruding from the ignition needle 1.
[0068] In this embodiment, see Figure 5 The connecting hole 2220 has a side opening, through which the ignition needle 1 can be inserted into the connecting hole 2220. This configuration allows the ignition needle 1 to be inserted into or removed from the side opening of the connecting hole 2220, facilitating the assembly and disassembly of the ignition needle 1 and the swing structure 22, and is beneficial for later inspection and maintenance.
[0069] Of course, in other embodiments, the connecting hole 2220 can also be designed as a strip hole, and the second limiting part 12 can be designed to be detachably connected to the ignition needle 1. For example, the second limiting part 12 can be threadedly connected to the ignition needle 1. During assembly, after the ignition needle 1 passes through the connecting hole 2220, the second limiting part 12 is screwed onto the ignition needle 1 to limit the second end of the swing structure 22 between the first limiting part 11 and the second limiting part 12.
[0070] In other alternative embodiments, the second end of the swing structure 22 can also be rotatably connected to the ignition needle 1. During the swinging process of the swing structure 22, the second end of the swing structure 22 rotates adaptively relative to the ignition needle 1 to prevent the swing structure 22 from interfering with the up-and-down movement of the ignition needle 1 and to ensure smooth up-and-down movement of the ignition needle 1. For example, a protruding post can be provided on the side wall of the ignition needle 1, and the second swing member 222 of the swing structure 22 can be hinged to the protruding post.
[0071] This embodiment also provides a gas stove, including a base shell 100, a burner head 200, a burner cap 300, and an ignition device as described above. The burner head 200 and the drive mechanism 2 of the ignition device are both disposed within the base shell 100, and the burner cap 300 is located on the burner head 200. The ignition needle 1 of the ignition device is movably disposed on the burner head 200, and when the ignition needle 1 is ignited, it can ignite the gas output from the flame hole of the burner cap 300.
[0072] Furthermore, the gas stove also includes a thermocouple 400, a gas valve 500, and a controller 600. The burner head 200 is connected to the gas pipeline supplying gas. The gas valve 500 is installed on the gas pipeline to control the amount of gas supplied to the burner head 200. The controller 600 is communicatively connected to the drive unit 21 and the gas valve 500. The controller 600 can control the opening and closing of the drive unit 21 according to the ignition command, so that the ignition needle 1 switches to the ignition position or the retracted position. The controller 600 can also control the opening degree of the gas valve 500 according to the firepower adjustment command to adjust the firepower. The thermocouple 400 is installed on the burner head 200 to detect whether there is a flame at the burner cap 300. When the flame at the burner cap 300 is extinguished, the thermocouple 400 detects the flameout, and the controller 600 controls the gas valve 500 to close to prevent gas leakage.
[0073] In a gas stove employing this ignition device, when ignition is required, the driving component 21 drives the first end of the swing structure 22 to rotate around its rotation axis. This causes the second end of the swing structure 22 to move the ignition needle 1 to the ignition position, igniting the gas output from the burner holes of the burner cap 300. After ignition, the driving component 21 drives the first end of the swing structure 22 to rotate in the opposite direction, causing the second end of the swing structure 22 to move the ignition needle 1 to the retracted position. The ignition needle 1 then avoids being constantly within the flame, reducing its burning time and extending its lifespan. Simultaneously, it prevents ignition leakage and avoids contact with the yellow flame caused by the burning needle 1, reducing the production of harmful gases and improving the safety of the stove. When cleaning the stovetop, the ignition needle 1 can be switched to the storage position by driving the swing structure 22 through the drive component 21, preventing the ignition needle 1 from being damaged by collision or scratching the user during cleaning. In addition, during the transportation of the stove, the ignition needle 1 can be switched to the storage position by driving the drive component 21, so that the ignition needle 1 is hidden, which can reduce the difficulty of packaging and prevent the ignition needle 1 from being damaged by collision during transportation.
