It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] It should be noted that, in the coordinate system XYZ provided in the present application, the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the back, the negative direction of the Y-axis represents the front, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0032] See also Figure 1 and Figure 2 An embodiment of the present application provides a gas stove for cooking food. The gas stove may include a bottom shell 9 and a pulse igniter 100 .

[0033] The bottom shell 9 serves as an appearance component of the gas stove and is used to protect the internal components of the gas stove. An installation opening 901 is provided at the bottom of the bottom shell 9. The contour shape and size of the installation opening 901 match the peripheral contour shape and size of the pulse igniter 100, so that the pulse igniter 100 can be installed and fixed to the bottom shell 9.

[0034] As an ignition component of the gas stove, the pulse igniter 100 mainly utilizes the pulse principle to generate continuous instantaneous electric sparks, thereby igniting the flame of the gas stove, so that the gas stove can burn stably.

[0035] Specifically, during production, the bottom shell 9 is placed on the assembly line, and the bottom of the bottom shell 9 contacts the transmission mechanism, and the pulse igniter 100 is pressed from top to bottom into the installation opening 901. Figure 2 The positive direction of the Z axis represents the top, and the negative direction of the Z axis represents the bottom, so that the pulse igniter 100 can be snap-fitted and installed on the bottom shell 9. Therefore, the pulse igniter 100 can be directly installed from the top of the bottom shell 9 from top to bottom without turning over the bottom shell 9, which can improve production efficiency.

[0036] See also Figures 3 to 5In some embodiments, the pulse igniter 100 includes a main housing 1 , an abutment member 2 and an elastic snap member 3 .

[0037] The main housing 1 has a mainboard installation cavity 101, which is used to place the mainboard. The mainboard is the core component of the pulse igniter 100. The mainboard realizes ignition control, voltage boosting, power management, safety protection and other functions through circuits and control logic, so that the gas stove can be stably, reliably and safely ignited and operated. The opening of the mainboard installation cavity 101 is located at the top of the main housing 1. Figure 3 The positive direction of the Z axis represents the side where the top of the main shell 1 is located, and the negative direction of the Z axis represents the side where the bottom of the main shell 1 is located. There is also a mainboard cover 4 on the top of the main shell 1, and the mainboard cover 4 is used to open or close the opening of the mainboard mounting cavity 101.

[0038] Optionally, when the mainboard is disposed in the mainboard installation cavity 101 , the mainboard cover 4 can cover the opening of the mainboard installation cavity 101 , and the mainboard cover 4 can be snap-fitted to the main shell 1 , so that the mainboard is firmly fixed in the mainboard installation cavity 101 .

[0039] The abutment 2 can be arranged on the circumferential side wall of the main shell 1, so that the abutment 2 protrudes outward from the circumferential side wall of the main shell 1, and the elastic snap member 3 is also arranged on the circumferential side wall of the main shell 1, and the elastic snap member 3 is located on the side of the abutment 2 facing the bottom of the main shell 1, and the elastic snap member 3 and the abutment 2 are arranged at a distance, so that a snap position 301 can be formed between the elastic snap member 3 and the abutment 2.

[0040] When installing the pulse igniter 100, the main shell 1 is pressed downward into the installation opening 901 of the bottom shell 9, so that the elastic clip 3 first contacts the side wall of the installation opening 901, and as the main shell 1 continues to be pressed downward, the elastic clip 3 passes through the installation opening 901, and the side wall of the installation opening 901 is snapped into the snap position 301, that is, the side wall of the installation opening 901 is snapped between the abutment 2 and the elastic clip 3, so that the main shell 1 is installed on the bottom shell 9, and the opening of the mainboard installation cavity 101 is located inside the bottom shell 9. Therefore, when installing the pulse igniter 100, the workers on the production line can directly install the main shell 1 from the top of the bottom shell 9 downward without turning over the bottom shell 9, which can improve production efficiency.

[0041] See also Figure 3 In some embodiments, the elastic snap member 3 is elastic and is used to snap with the bottom shell 9. The elastic snap member 3 includes a fixed end 31 and an elastic arm 32 that are connected to each other.

[0042] Specifically, the fixed end 31 can be connected to the circumferential outer wall of the main shell 1, so that the elastic snap member 3 is connected to the outer wall of the main shell 1 as a whole, and the elastic arm 32 is spaced apart from the circumferential outer wall of the main shell 1, so that there is a gap between the elastic arm 32 and the main shell 1, and the elastic arm 32 extends in a direction close to the abutment 2, so that a snap position 301 can be formed between the elastic arm 32 and the abutment 2.

[0043] When the main shell 1 is pressed downward, the elastic arm 32 can contact the side wall of the mounting opening 901, and the side wall of the mounting opening 901 squeezes the elastic arm 32 toward the side of the main shell 1 until the elastic arm 32 is separated from the side wall of the mounting opening 901, and the elastic arm 32 returns to its original state, so that the side wall of the mounting opening 901 is clamped between the abutment 2 and the elastic arm 32, and the elastic arm 32 can be supported on the bottom shell 9, so that there is no need to set a hollow structure on the side wall of the main shell 1, and the elastic arm 32 can be squeezed through the mounting opening 901, which can prevent insects from entering the pulse igniter 100 from the connection between the elastic arm 32 and the main shell 1, and can play an insect-proof role.

[0044] See also Figure 3 and Figure 4 In some embodiments, the circumferential outer wall of the main shell 1 can be provided with an avoidance groove 102, the notch of the avoidance groove 102 is arranged toward the elastic clip 3, and the avoidance groove 102 is extended along the extension direction of the elastic arm 32, and the avoidance groove 102 is arranged opposite to the elastic arm 32, so that the avoidance groove 102 can be used to accommodate at least a portion of the elastic arm 32.

[0045] Based on the above embodiment, when installing the pulse igniter 100, the main shell 1 is pressed from top to bottom into the installation opening 901 of the bottom shell 9. During the pressing process, the elastic arm 32 is squeezed toward the avoidance groove 102 by the side wall of the installation opening 901, and the elastic arm 32 will be squeezed into the avoidance groove 102, so that a part of the main shell 1 can pass through the installation opening 901 until the abutment 2 abuts against the upper surface of the bottom shell 9, and the elastic arm 32 abuts against the lower surface of the bottom shell 9 after passing through the installation opening 901, so that the side wall of the installation opening 901 is clamped between the elastic arm 32 and the abutment 2. Therefore, by providing the avoidance groove 102 on the circumferential outer wall of the main shell 1, the elastic arm 32 can be partially accommodated in the avoidance groove 102 when being squeezed and pass through the installation opening 901, thereby facilitating the installation of the pulse igniter 100.

[0046] See also Figure 3 and Figure 4In some embodiments, elastic clips 3 are respectively provided on the two opposite circumferential side walls of the main shell 1, and abutment members 2 can be respectively provided on the two opposite sides of each elastic clip 3 along the circumference of the main shell 1, so that the two opposite sides of the main shell 1 can be snapped with the bottom shell 9, so that the pulse igniter 100 can be installed more firmly.

[0047] Specifically, the overall shape of the main shell 1 is generally in the shape of a cube, and one of the circumferential side walls of the main shell 1 is provided with two elastic clips 3, and along the circumference of the main shell 1, the two elastic clips 3 on the same side wall are arranged at intervals, and each elastic clip 3 is provided with abutments 2 on both sides. At the same time, another circumferential side wall arranged opposite to the circumferential side wall with the elastic clip 3 is also provided with two elastic clips 3. The main shell 1 is pressed from top to bottom into the installation opening 901, so that the opposite sides of the main shell 1 can be snapped with the bottom shell 9.

[0048] Of course, the specific shape of the main shell 1 is not limited. Along the circumference of the main shell 1, a plurality of elastic snap members 3 are arranged at intervals on the circumferential side walls of the main shell 1, and abutment members 2 are respectively provided on the opposite sides of each elastic snap member 3, so that a plurality of snap positions 301 are formed on the circumferential side walls of the main shell 1, and the plurality of snap positions 301 are arranged in sequence at intervals along the circumference of the main shell 1, so that the main shell 1 can form a plurality of snap-in points with the bottom shell 9, thereby increasing the stability of the snap-in.

[0049] See also Figure 6 In some embodiments, the main shell 1 may also have a battery installation cavity 103 and a battery cover 5. The battery installation cavity 103 can be used to place a battery, and the battery can be used to power the mainboard. The opening of the battery installation cavity 103 can be set at the bottom of the main shell 1. When the main shell 1 is installed on the bottom shell 9, the opening of the battery installation cavity 103 is located outside the bottom shell 9, so that the battery can be easily replaced.

[0050] Optionally, one side of the battery cover 5 can be rotatably connected to the bottom of the main shell 1, and the opening of the battery installation cavity 103 can be opened or closed by rotating the battery cover 5, while the other side of the battery cover 5 can be snap-engaged with the main shell 1, so that the battery cover 5 is connected to the main shell 1 to prevent the battery from falling off from the battery installation cavity 103.

[0051] Therefore, by integrally forming the mainboard mounting cavity 101 and the battery mounting cavity 103 on the main shell 1, the structure of the entire pulse igniter 100 becomes more compact, the required space is reduced, and it is convenient to realize integrated installation on equipment such as gas stoves. By setting the battery cover 5 and designing the opening of the battery mounting cavity 103 at the bottom of the main shell 1, the user only needs to open the battery cover 5 when replacing the battery, which greatly improves the convenience.

[0052] See also Figure 3 In some embodiments, the pulse igniter 100 may further include a positive electrode sheet 6 and a negative electrode sheet 7, which may be arranged at intervals in the battery installation cavity 103, and a first through hole 104 and a second through hole 105 are provided on the top of the main housing 1, and the first through hole 104 and the second through hole 105 are respectively connected to the battery installation cavity 103, so that one end of the positive electrode sheet 6 can extend from the first through hole 104 to form a positive electrode terminal 61, and one end of the negative electrode sheet 7 can extend from the second through hole 105 to form a negative electrode terminal 71, so that the positive electrode terminal 61 and the negative electrode terminal 71 are both located at the top of the main housing 1, combined with Figure 1 The connection terminals extending from the main board are also located at the top of the main shell 1. The main board can be electrically connected to the positive terminal 61 and the negative terminal 71 through wires (not shown in the drawings), so that the battery in the battery installation cavity 103 can supply power to the main board.

[0053] Therefore, a first through hole 104 and a second through hole 105 are provided on the top of the main shell 1, and the positive electrode sheet 6 and the negative electrode sheet 7 are extended from the first through hole 104 and the second through hole 105 respectively, so that the mainboard can be conveniently electrically connected with the positive electrode sheet 6 and the negative electrode sheet 7, so that the wiring arrangement of the pulse igniter 100 is more reasonable, which can further save installation space.

[0054] See also Figure 4 and Figure 6 In some embodiments, one end of the positive electrode sheet 6 away from the positive electrode terminal 61 can extend from the battery installation cavity 103 to form a positive electrode detection terminal 62, and one end of the negative electrode sheet 7 away from the negative electrode terminal 71 can also extend from the battery installation cavity 103 to form a negative electrode detection terminal 72. It can also be said that both the positive electrode sheet 6 and the negative electrode sheet 7 extend from the battery installation cavity 103 to form a positive electrode detection terminal 62 and a negative electrode detection terminal 72, respectively, and the positive electrode detection terminal 62 and the negative electrode detection terminal 72 can be bent in a direction away from each other, so that the positive electrode sheet 6 and the negative electrode sheet 7 form an L-shaped structure.

[0055] When it is necessary to detect whether the positive electrode sheet 6 and the negative electrode sheet 7 are installed properly, two external probes can be respectively contacted with the positive electrode detection terminal 62 and the negative electrode detection terminal 72 through automated equipment, thereby realizing automatic power-on detection of whether the positive electrode sheet 6 and the negative electrode sheet 7 are conductive. This can save the manual installation process of battery testing and improve the detection speed.

[0056] See also Figure 6In some embodiments, the side wall defining the opening of the battery installation cavity 103 can have two avoidance notches 106 arranged opposite to each other, and the positive detection terminal 62 and the negative detection terminal 72 can extend from the two avoidance notches 106 respectively, so that the positive detection terminal 62 and the negative detection terminal 72 are respectively located outside the battery installation cavity 103, thereby arranging the avoidance notches 106 to facilitate the positive detection terminal 62 and the negative detection terminal 72 to extend along the opening of the battery installation cavity 103, and the avoidance notches 106 can be used to accommodate at least part of the positive detection terminal 62 and at least part of the negative detection terminal 72, thereby preventing a gap from appearing between the battery cover 5 and the main shell 1 when the battery cover 5 is closed, resulting in a loose closure.

[0057] In addition, the positive detection terminal 62 and the negative detection terminal 72 both extend outward along the edge of the opening of the battery installation cavity 103. When the battery cover 5 closes the battery installation cavity 103, the battery cover 5 can cover the avoidance gap 106, fixing the positive detection terminal 62 and the negative detection terminal 72 in the avoidance gap 106, so that when using a probe for detection, the positive detection terminal 62 and the negative detection terminal 72 can be prevented from moving.

[0058] See also Figure 6 In some embodiments, bosses 8 can be provided on the two opposite lateral side walls of the main shell 1, and the two bosses 8 are respectively arranged opposite to the avoidance notch 106. In other words, the table top of the boss 8 is connected to the wall surface that defines the avoidance notch 106, so that after the positive pole detection terminal 62 and the negative pole detection terminal 72 are respectively extended through the two avoidance notches 106, the positive pole detection terminal 62 and the negative pole detection terminal 72 can be respectively placed on the table tops of the two bosses 8.

[0059] When the probe is used to contact the positive detection terminal 62 and the negative detection terminal 72, the two bosses 8 can provide support for the positive detection terminal 62 and the negative detection terminal 72 respectively, thereby enhancing the structural strength of the positive detection terminal 62 and the negative detection terminal 72, and preventing the positive detection terminal 62 and the negative detection terminal 72 from being bent when the probe contacts the positive detection terminal 62 and the negative detection terminal 72, resulting in inaccurate detection.

[0060] Optionally, the surface of the boss 8 is coplanar with the wall surface defining the avoidance gap 106 , so that the positive electrode detection terminal 62 and the negative electrode detection terminal 72 can be smoothly placed on the surfaces of the two bosses 8 after extending out of the two avoidance gaps 106 .

[0061] See also Figure 4 In some embodiments, along the direction away from the main housing 1, that is, along Figure 4 In the negative direction of the X-axis, the length of the positive electrode detection terminal 62 on the boss 8 is h. Figure 4In the positive direction of the middle X-axis, the length of a section of the negative pole detection terminal 72 mounted on the boss 8 is also h, and h satisfies: h≥8mm, which facilitates the external probe to contact the positive pole detection terminal 62 and the negative pole detection terminal 72, so that the external probe can power the mainboard through the positive pole detection terminal 62 and the negative pole detection terminal 72 for detection, thereby improving the accuracy of the detection.

[0062] See also Figure 7 and Figure 8 In some embodiments, the vertical distance from the elastic arm 32 to the circumferential side wall of the main shell 1 is d, and the distance d gradually increases from the elastic snap member 3 toward the abutment member 2, so that the elastic arm 32 is set at an angle with the circumferential side wall of the main shell 1, and the open end of the angle is set toward the top of the main shell 1.

[0063] Specifically, when the main shell 1 is pressed from top to bottom, the fixed end 31 of the elastic arm 32 first contacts the side wall of the mounting opening 901, so that the main shell 1 can be easily pressed into the mounting opening 901, and the elastic arm 32 can be easily squeezed toward the side where the main shell 1 is located. When the elastic arm 32 is separated from the side wall of the mounting opening 901, the free end of the elastic arm 32 is set toward the bottom shell 9, so that the side wall of the mounting opening 901 is firmly engaged with the snap-in position 301. Therefore, the main shell 1 can be easily and firmly installed on the bottom shell 9 from top to bottom.

[0064] See also Figure 8 In some embodiments, along the installation direction of the main shell 1, the distance between the elastic snap member 3 and the abutment member 2 is a, so that the width of the snap position 301 is a, and the side wall thickness of the installation opening 901 snapped to the snap position 301 is b, and a and b satisfy: 0≤ab≤0.2mm.

[0065] Among them, 0≤ab makes the width of the snap-in position 301 greater than or equal to the side wall thickness of the mounting opening 901, so that the side wall of the mounting opening 901 can be snapped into the snap-in position 301, so that the main shell 1 can be snapped and installed on the bottom shell 9; and ab≤0.2mm, it can prevent the side wall of the mounting opening 901 from shaking greatly when it is snapped into the snap-in position 301, so that the structure of the main shell 1 snapped onto the bottom shell 9 is more secure. For example, the side wall thickness of the mounting opening 901 is b=0.6mm, and the distance a between the elastic snap member 3 and the abutment 2 satisfies: 0.6mm≤a≤0.7mm, so that the side wall of the mounting opening 901 can be firmly snapped into the snap-in position 301.

[0066] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
