[0052] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0053] like Figures 1 to 3 As shown, the present embodiment provides a burner 1, which is applied to a stove 100. The burner 1 comprises a fire cover 12, an ignition needle 13 and a connecting piece 15. Along the radial direction of the fire cover 12, the upper edge of the fire cover 12 exceeds the side wall of the fire cover 12, so that the projection of the upper edge of the fire cover 12 in the axial direction of the fire cover 12 covers the side wall of the fire cover 12. The side wall of the fire cover 12 is provided with a groove 14, and the groove 14 is used to accommodate the ignition end of the ignition needle 13. When the ignition end is accommodated in the groove 14, the projection of the wall surface of the groove 14 in the axial direction of the fire cover 12 covers the ignition end of the ignition needle 13. The connecting piece 15 is connected to the ignition needle 13 for switching the state of the ignition needle 13. In the first state, the ignition end of the ignition needle 13 is located in the groove 14. In the second state, the connecting piece 15 drives the ignition end of the ignition needle 13 to move in a direction away from the groove 14, so that the ignition end of the ignition needle 13 is located in the combustion area. Specifically, the first state is the state in which ignition is completed, that is, the cooking state. At this time, the ignition end can be protected by the upper edge of the fire cover 12 and the wall of the groove 14 to prevent water, oil, vegetable residues and overflow generated during the cooking process from adhering to the ignition needle 13 and causing ignition failure. The above-mentioned structural form is adopted to increase the service life of the ignition needle 13, thereby improving the user experience. The second state is the state during ignition. At this time, the ignition end is driven out of the groove 14 by the connecting piece 15, so that the gas ejected from the fire cover 12 can be ignited by the ignition end, thereby realizing the normal ignition of the burner 1.

[0054] It should be specifically explained that when the ignition needle 13 ignites, its ignition end needs to have a certain preset distance range from the fire cover 12. Only when the ignition end is within the preset distance range can it ignite the gas sprayed from the fire cover 12. Therefore, the ignition end mentioned above being located in the combustion area means that the ignition end is located within the preset distance range, and at this time, the ignition needle 13 can achieve normal ignition. In this embodiment, when the axis of the ignition needle 13 is in the vertical direction, ignition is performed through the ignition end. In other embodiments, the preset distance range and the combustion area can be defined according to the type of burner 1, etc., and no specific limitation is made here on the preset distance range and the combustion area.

[0055] The number of grooves 14 can correspond to the number of ignition needles 13 one by one; of course, some of the ignition needles 13 can also be located in the grooves 14. In other words, the number of grooves 14 can be adjusted according to actual needs, and there is no limitation here. In addition, the length of the groove 14 in the axial direction of the fire cover 12 can also be adjusted according to actual needs, and there is no limitation on the length of the groove 14. In addition, since the ignition needles 13 are arranged on the outer wall of the fire cover 12, the side wall of the fire cover 12 mentioned above refers to the outer wall. In other embodiments, the side wall of the fire cover 12 can be adjusted to refer to the outer wall or the inner wall according to actual design requirements, and there is no limitation here.

[0056] like Figure 3 As shown, the burner 1 further includes a body 11, a fire cover 12 is arranged on the body 11, and an ignition needle 13 is rotatably connected to the body 11 or the fire cover 12. With the above-mentioned structural form, the ignition needle 13 is rotatably connected to the body 11 or the fire cover 12, so as to realize the switching between the first state in which the ignition end is located in the groove 14 and the second state in which the ignition end is separated from the groove 14.

[0057] The connecting member 15 is connected to the first connecting position of the ignition needle 13, and the body 11 or the ignition cover 12 is rotatably connected to the second connecting position of the ignition needle 13 away from the ignition end; wherein, there is a gap between the first connecting position and the second connecting position in the axial direction of the ignition needle 13. With the above-mentioned structural form, the connecting member 15 can drive the ignition needle 13 to rotate around the body 11 or the ignition cover 12, so as to realize the switching between the first state and the second state.

[0058] In the present embodiment, the first connection position is located at the bottom of the ignition needle 13; the second connection position is located in the middle of the ignition needle 13. The above-mentioned structural form facilitates the connection between the connecting member 15 and the ignition needle 13, and facilitates the connecting member 15 to drive the ignition needle 13 to move. In other embodiments, the settings of the first connection position and the second connection position can be adjusted according to actual needs, and are not limited here. In addition, in the present embodiment, the body 11 is rotatably connected to the second connection position of the ignition needle 13 away from the ignition end. In other embodiments, the second connection position can also be rotatably connected to the fire cover 12.

[0059] See also Figure 3 It is understood that the burner 1 also includes a first elastic member 16, which is connected to the ignition needle 13 and is used to drive the ignition needle 13 to return to the initial position. The above-mentioned structural form facilitates the ignition needle 13 to return to the initial position, and improves the efficiency of switching between the first state and the second state. In other words, in the first state, the user can use the connecting member 15 to make the ignition end disengage from the groove 14 so that the ignition needle 13 can ignite the gas ejected from the fire cover 12. After the ignition is completed, the user cancels the force applied to the connecting member 15. At this time, under the action of the first elastic member 16, the ignition needle 13 returns to the initial position. At this time, the ignition end is located in the groove 14, so that the ignition end can be protected by the upper edge of the fire cover 12 and the wall of the groove 14.

[0060] In this embodiment, the first elastic member 16 is a spring. In addition, in this embodiment, the elastic force direction of the first elastic member 16 is along the rotation direction of the ignition needle 13, thereby increasing the speed at which the ignition needle 13 returns to the initial position. In addition, in this embodiment, the two ends of the first elastic member 16 are respectively connected to the ignition needle 13 and the body 11. In other embodiments, the two ends of the first elastic member 16 may also be respectively connected to the ignition needle 13 and the ignition cover 12.

[0061] The burner 1 further comprises a mounting member and a fixing member, the fixing member is connected to the mounting member, the mounting member is sleeved on the ignition needle 13, a mounting hole is provided on the body 11 or the fire cover 12, the fixing member extends into the mounting hole and is rotatably connected with the mounting hole; wherein the axial direction of the mounting hole is not parallel to the movement direction of the ignition needle 13. With the above-mentioned structural form, the ignition needle 13 is rotated around the body 11 through the mounting member and the fixing member, which has the characteristics of simple structure.

[0062] In this embodiment, the fixing member and the mounting member are integrally formed, thereby improving the stability of the connection between the body 11 and the ignition needle 13. In other embodiments, the fixing member and the mounting member may also be separately provided, so that if one of the fixing member and the mounting member is damaged, only the damaged fixing member or the mounting member needs to be replaced for normal use, thereby reducing the cost of use.

[0063] like Figure 1 and Figure 2 As shown, the fire cover 12 includes a fire cover body 121 and a protective member 122. The protective member 122 is connected to the upper end of the fire cover body 121. In the radial direction of the fire cover 12, the length of the protective member 122 exceeds the length of the fire cover body 121, so that the projection of the protective member 122 in the axial direction of the fire cover 12 covers the fire cover body 121; the groove 14 is provided on the fire cover body 121. Specifically, the fire cover body 121 can be protected by the protective member 122, so that liquids such as overflow can be prevented from adhering to the fire cover body 121 and affecting the normal use of the fire cover body 121, thereby improving the normal use of the fire cover body 121. In addition, by adopting the above-mentioned structural form, the ignition end can also be protected by the protective member 122, so that overflow liquids can be attached to the ignition needle 13 and cause ignition failure, thereby improving the service life of the ignition needle 13.

[0064] In this embodiment, the fire cover body 121 and the protective member 122 can be integrally formed, thereby improving the structural strength and stability of the fire cover 12. In other embodiments, the fire cover body 121 and the protective member 122 can also be separately provided, so that if one of the fire cover body 121 and the protective member 122 is damaged, only the damaged fire cover body 121 or the protective member 122 needs to be replaced for normal use, thereby reducing the use cost.

[0065] In specific use, in the axial direction of the fire cover 12, the projection length of the protective member 122 close to the groove 14 is greater than the projection length of the protective member 122 away from the groove 14. With the above structure, the ignition end can be further protected by the protective member 122, thereby further improving the service life of the ignition needle 13.

[0066] See also Figures 4 to 6 For understanding, the present embodiment further provides a stove 100, which includes the burner 1 as described above. Specifically, the ignition end can be protected by the upper edge of the fire cover 12 and the wall of the groove 14, so as to prevent water, oil, vegetable residue and overflow generated during cooking from adhering to the ignition needle 13 and causing ignition failure. The above structural form is adopted to increase the service life of the ignition needle 13, thereby improving the user experience.

[0067] like Figures 4 to 6 As shown, the stove 100 further includes a valve stem 17, and the two ends of the connecting member 15 are respectively connected to the ignition needle 13 and the valve stem 17, and the valve stem 17 is used to drive the ignition end to move through the connecting member 15. With the above structural form, the user can switch between the first state and the second state through the valve stem 17, which has the characteristic of convenient switching.

[0068] like Figure 6As shown, during specific use, the valve stem member 17 includes a valve stem 171, a fixed plate 172, a moving plate 173 and a second elastic member 174. The valve stem 171 passes through the fixed plate 172 and the moving plate 173, and the portion of the valve stem 171 close to the moving plate 173 is connected to the moving plate 173. The second elastic member 174 is sleeved on the valve stem 171, and the two ends of the second elastic member 174 are respectively abutted against the fixed plate 172 and the moving plate 173. The end of the connecting member 15 away from the ignition needle 13 is connected to the moving plate 173. The valve stem 171 is used to drive the moving plate 173 to move in a direction close to the fixed plate 172, so as to drive the ignition end to move through the connecting member 15. With the above structure, when the user presses the valve stem 171 to achieve ignition through the ignition needle 13, the valve stem 171 can drive the moving plate 173 to move in the direction close to the fixed plate 172, so that the moving plate 173 drives the ignition end to disengage from the groove 14 through the connecting member 15 during the movement, and then the gas ejected from the ignition cover 12 can be ignited through the ignition end to achieve ignition. After the ignition is completed, the user stops pressing the valve stem 171, and the ignition needle 13 returns to its initial position under the drive of the second elastic member 174, so that the ignition end can be protected by the upper edge and the groove 14, thereby preventing the overflow generated during the cooking process from adhering to the ignition end, and further preventing the ignition needle 13 from igniting failure.

[0069] During actual use, the hardness of the connecting member 15 is relatively soft, so that the connecting member 15 can avoid other components when connecting the ignition needle 13 and the moving plate 173, thereby improving the reliability of the connection.
