Description

Technical Field

[0001] The utility model relates to an interlocking ignition device for a portable mini stove, belonging to the technical field of portable gas cookers. Background Art

[0002] For most existing mini stove products used for mountaineering, the gas switch device and the ignition device are separate (as shown in Figure 1 ), or ignition requires an external fire source (as shown in Figure 2 ). In this case, the ignition device and the gas switch need to be operated sequentially. First, the gas is turned on, and then the ignition device is pressed. The two hands need to cooperate in operation, which requires very skilled continuous operation. The operation is complex and difficult to control. For product flow control, there is no limit on the angle. For most products, it takes more than one turn to rotate to the maximum fire position. For users, it is not easy to accurately determine the initial opening position of the valve body, resulting in poor control over the size of the combustion flame of the stove body. Content of the Utility Model

[0003] To solve the defects existing in the prior art, the purpose of the utility model is to provide an interlocking ignition device for a portable mini stove, which can simplify the operation and facilitate the control of the stove.

[0004] The technical solution of the utility model is: an interlocking ignition device for a portable mini stove, including a knob connected to the valve body, an igniter is fixed on the valve body, and the knob controls the start of the igniter through an interlocking rotating block.

[0005] The igniter is fixed on the side of the valve body.

[0006] The knob is connected to the flow control shaft of the valve body.

[0007] The interlocking rotating block is rotatably connected to a fixed shaft fixed on the valve body.

[0008] The interlocking rotating block includes contact a and contact b. The push block on the knob pushes the interlocking rotating block to rotate through contact a, and contact b is used to trigger the ignition press head of the igniter to make the igniter work.

[0009] The interlocking rotating block is limited by an upper limit screw, and the upper limit screw is threadedly connected to the fixed shaft.

[0010] The igniter is connected to the ignition head through a lead wire, and the ignition head is located at the burner head on the top of the valve body.

[0011] The gas cylinder is detachably connected to the valve body.

[0012] The beneficial effect of the utility model is: the interlocking control of the valve body and the igniter can be realized by rotating the knob, simplifying the operation of the mini stove. Description of the Drawings

[0020] The following further describes the present utility model in conjunction with the attached Figures 3 - 6 drawings:

[0021] A linkage ignition device for a portable mini - stove, comprising a knob 1 connected to the flow control shaft 8 of the valve body 4, an igniter 3 is fixed on the side of the valve body 4, the knob 1 controls the start of the igniter 3 through a linkage rotating block 2, the linkage rotating block 2 includes a contact a 2.1 and a contact b 2.2, a push block 1.1 on the knob 1 pushes the linkage rotating block 2 to rotate through the contact a 2.1, and the contact b 2.2 is used to trigger the ignition pressure head 3.1 of the igniter 3 to make the igniter work. The igniter 3 is connected to the ignition head 7 through a lead wire 10, and the ignition head 7 is located at the burner head 6 on the top of the valve body 4.

[0022] The linkage rotating block 2 is rotatably connected to a fixed shaft 9 fixed on the valve body 4, and the linkage rotating block 2 is limited by an upper limit screw 5 to prevent the linkage rotating block 2 from axially moving up and down along the fixed shaft 9. The upper limit screw is threadedly connected to the fixed shaft 9.

[0023] The gas cylinder is detachably connected to the valve body 4.

[0024] The working process of the present utility model is as follows:

[0025] During ignition, rotate the knob 1. When it is rotated to the position where the gas outlet flow rate of the valve body 4 is the largest, the push block 1.1 contacts the contact a 2.1. Continue to rotate the knob 1, and the push block 1.1 drives the linkage rotating block 2 to rotate through the contact a 2.1, so that the contact b 2.2 presses the ignition head 3.1 of the igniter 3, and the igniter 3 works. The ignition head 7 ignites at the burner head 6. At this time, the burner head 6 has been supplied with gas and can be directly ignited. Release the knob 1, and the ignition head 3.1 rebounds under the action of the internal spring force, driving the linkage rotating block 2 to rotate in the reverse direction. The linkage rotating block 2 drives the knob 1 to rotate in the reverse direction through the contact a 2.1. When the linkage rotating block 2 rotates back to the initial position, it no longer pushes the knob 1, and the stop position of the knob 1 is the position where the gas outlet volume of the valve body 4 is the largest, that is, the flame of the burner head is the largest at this time. The user can continue to rotate the knob 1 in the reverse direction as needed to adjust the size of the flame of the burner head 6, which is convenient for the user to operate. The igniter 3 in the present utility model is an existing product available on the market.

[0026] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
