[0043] The pulse igniter 200 in the three-in-one ignition mechanism is connected to one side of the box body 110, and the keypad 300 is connected to the side of the pulse igniter 200 away from the box body 110, so that the battery box 100, the pulse igniter 200 and the keypad 300 are three-in-one. On the one hand, the three-in-one ignition mechanism is more efficient when assembled to the gas stove; on the other hand, it can be purchased in a centralized manner to simplify the purchasing process; on the third hand, since the pulse igniter 200 is sandwiched between the keypad 300 and the box body 110, The shell thickness on both sides of the pulse igniter 200 can be appropriately reduced, and the thickness of the side of the box body 110 facing the pulse igniter 200 and the thickness of the side of the keypad 300 facing the pulse igniter 200 can be appropriately reduced, thereby reducing the thickness and weight of the entire ignition mechanism, and then reducing the thickness and weight of the gas stove; fourthly, due to the integrated connection, the battery 400 can provide power to the pulse igniter 200 and the keypad 300 at the same time, thereby reducing the wiring layout and being less likely to have poor contact problems.

[0044] In some embodiments, a first mounting groove 111 is provided on one side of the box body 110, and the pulse igniter 200 is at least partially installed in the first mounting groove 111. A second mounting groove 112 is provided on the other side of the box body 110, and the battery 400 is installed in the second mounting groove 112. The above arrangement can provide a certain degree of protection for the pulse igniter 200 and the battery 400, and can appropriately reduce the shell thickness around the pulse igniter 200, thereby reducing costs.

[0045] The pulse igniter 200 includes a pulse housing 210 , which has a receiving groove opening downward, and the bottom of the first mounting groove 111 is surrounded by a receiving cavity, in which a circuit board 250 is arranged.

[0046] Further, in some embodiments, the battery box 100 includes a cover 120, which can be covered on the box body 110 and can close the second mounting groove 112. This arrangement allows the battery 400 to be protected in all directions.

Among them, the other end of the cover 120 is provided with a handle to facilitate hand-held opening and closing of the cover 120. Among them, the cover 120 is provided with reinforcing ribs, so that the thickness of the cover 120 can be reduced and the strength is high.

[0047] In some embodiments, the pulse igniter 200 is snap-connected with the box body 110. The pulse igniter 200 is snap-connected with the key board 300. With the above connection method, the assembly efficiency of the three-in-one ignition mechanism is improved.

[0048] Specifically, the keypad 300 includes a key housing 310 and a first snap 311 disposed on the key housing 310, the pulse igniter 200 includes a pulse housing 210 and a first snap slot 211 disposed on the pulse housing 210, and the first snap 311 snaps into the first snap slot 211. The pulse igniter 200 includes a second snap slot 212 disposed on the pulse housing 210, and the battery box 100 includes a second snap 113 disposed on the box body 110, and the second snap 113 snaps into the second snap slot 212. The first snap slot 211 and the second snap slot 212 are concentrated in the pulse housing 210, and the first snap 311 and the second snap 113 are respectively disposed in the key housing 310 and the box body 110, which facilitates design and injection molding manufacturing, and reduces manufacturing costs.

[0049] In the first implementation of this embodiment, two groups of first buckles 311 are provided, and the two groups of first buckles 311 are separated on both sides of the key housing 310 along the X direction; two groups of first slots 211 are provided, and the two groups of first slots 211 are separated on both sides of the pulse housing 210 along the X direction. The above arrangement helps to improve the firmness of the connection between the key plate 300 and the pulse housing 210.

[0050] In the second implementation of this embodiment, two groups of second buckles 113 are provided, and the two groups of second buckles 113 are separated on both sides of the box body 110 along the Y direction, and two groups of second slots 212 are provided, and the two groups of second slots 212 are separated on both sides of the pulse housing 210 along the Y direction. The above arrangement helps to improve the firmness of the connection between the pulse housing 210 and the box body 110.

[0051] In the third implementation of the present embodiment, there are two groups of first buckles 311, and the two groups of first buckles 311 are separated on both sides of the button housing 310 along the X direction; there are two groups of first slots 211, and the two groups of first slots 211 are separated on both sides of the pulse housing 210 along the X direction; there are two groups of second buckles 113, and the two groups of second buckles 113 are separated on both sides of the box body 110 along the Y direction; there are two groups of second slots 212, and the two groups of second slots 212 are separated on both sides of the pulse housing 210 along the Y direction, and the X direction is perpendicular to the Y direction. The above arrangement separates the slotting directions of the pulse housing 210, avoids slotting on the same side wall, and improves the self-strength of the pulse housing 210 under the premise of unchanged thickness.

[0052] Each group of first buckles 311 has one or two, each group of second buckles 113 has two, and accordingly, each group of first slots 211 has one or two, and each group of second slots 212 has two.

[0053] In order to improve the connection accuracy between the pulse housing 210 and the box body 110 , in some embodiments, the box body 110 is provided with a positioning groove, and the pulse housing 210 is provided with a positioning plate, and the positioning plate can be inserted into the positioning groove.

[0054] The box body 110, the pulse igniter 200 and the key plate 300 are arranged in sequence along the Z direction, and the Z direction, the X direction and the Y direction are perpendicular to each other. The above arrangement makes the connection between the box body 110, the pulse igniter 200 and the key plate 300 more compact, and the box body 110 and the key plate 300 are separated on the upper and lower sides of the pulse igniter 200, so that the thickness of the upper and lower side walls of the pulse housing 210 can be reduced, and the thickness of the upper side wall of the box body 110 and the key housing 310 can also be reduced, thereby reducing the thickness of the entire three-in-one ignition mechanism in the Z direction.

[0055] Regarding the power supply mode of the battery 400, in some embodiments, the battery box 100 includes an electrical connection assembly electrically connected to the battery 400, the electrical connection assembly includes two first terminals 130 and two second terminals 140, the length of the first terminal 130 is smaller than the second terminal 140, the pulse igniter 200 includes two first contacts 220 provided on the pulse housing 210, the two first terminals 130 are respectively abutted with the two first contacts 220; the pulse housing 210 is provided with a through hole 230, the keypad 300 includes two second contacts 320 provided on the key housing 310, the two second terminals 140 are passed through the through hole 230, and are respectively abutted with the two second contacts 320. It should be noted that the two ends of the battery 400 are respectively connected to the two first terminals 130 through wires, and the two ends of the battery 400 are respectively connected to the two second terminals 140 through wires.

[0056] On the one hand, the above arrangement enables the battery 400 to supply power to the pulse igniter 200 and the keypad 300 at the same time; on the other hand, the arrangement of the through hole 230 makes the structure of the electrical connection assembly more centralized and shortens the length of the line supplying power to the keypad 300 as much as possible, thereby reducing costs and the probability of failure.

[0057] Regarding the relative position relationship between the through hole 230 and the first contact 220, in some embodiments, the two first contacts 220 are located on both sides of the through hole 230. The above arrangement enables the two longer second terminals 140 to be located between the two shorter first terminals 130, thereby protecting the longer second terminals 140 and reducing the probability of the second terminals 140 being bent due to external collisions.
