Description

Technical Field

[0001] The present invention relates to the technical field of stoves, in particular to a quick-install ignition needle and a stove. Background Art

[0002] The ignition pin is the key component responsible for igniting the flame in a gas stove. It ignites the gas by releasing a high-voltage electric spark. Its core principle is similar to that of a lighter. When the user presses the knob of the gas stove and turns it, the igniter sends a high-voltage current to the ignition pin, generating an electric spark at its tip. When these electric sparks come into contact with the gas ejected from the fire hole, they instantly ignite the gas and form a flame. Traditional ignition pins rely on fixings such as retaining springs and nuts, which require special tools (such as wrenches and screwdrivers) to rotate and tighten. The operation is complicated and time-consuming. For example, after inserting the ignition pin into the mounting hole, it is necessary to screw on the nuts on the outer wall of the ignition pin above and below the mounting hole in turn. The same applies to disassembly. This installation method is not only cumbersome to operate, but also inconvenient to use inside the narrow stove. Summary of the Invention

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example See also Figure 1-8In an embodiment of the present invention, a quick-install ignition needle comprises an ignition needle body 200 and a fixing sleeve 300 mounted on the outside of the ignition needle body 200. The outer shell of the ignition needle body 200 is provided with a plurality of snap-fit grooves 210 at equal intervals. The fixing sleeve 300 comprises a cylindrical shell 310, a fixing ring 320, a quick-install assembly 330 and an annular sleeve 340. The cylindrical shell 310 is sleeved on the outside of the ignition needle body 200. The outer wall of the cylindrical shell 310 is symmetrically provided with four strip grooves 330. 11. The two opposite side walls of the strip groove 311 are provided with a sliding groove 312 at the upper position. The fixing ring 320 is fixed on the outer wall of the cylindrical shell 310. The quick-install assembly 330 includes a movable plate 331. The movable plate 331 is slidably mounted on the outer wall of the cylindrical shell 310. The movable plate 331 is located above the fixing ring 320. The outer wall of the movable plate 331 is fixedly connected with four ear plates 332 at equal angles. The bottom surface of the movable plate 331 is fixedly connected with four fixed plates symmetrically to each other. When the cam 331 is in the closed position, the cam 332 is in the closed position, and the cam 333 is in the open position, and the cam 333 is in the open position, and the cam 333 is in the open position, and the cam 333 is in the open position, and the cam 333 is in the open position, and the cam 333 is in the open position, and the cam 333 is in the open position, and the cam 333 is in the open position, and the cam 333 is in the open position, and the cam The top surface of the fixing ring 320 is provided with slots 321 at positions corresponding to the four strip grooves 311. A stove comprises a stove head 100 and the aforementioned quick-release ignition pin. The stove head 100 is provided with a mounting seat 110, and the quick-release ignition pin is plugged into a mounting hole of the mounting seat 110.

[0019] Specifically, the fixing sleeve 300 is sleeved on the outside of the ignition needle body 200 and is fixed by the engagement of the engaging block 341 with the engaging groove 210. When there is no external force, under the elastic force of the four springs 336, the bottom surface of the movable plate 331 is in close contact with the top surface of the fixing ring 320 by default. As the movable plate 331 moves downward, the fixing plate 333 moves downward synchronously. The connecting plate 334 and the rotating plate 335 rotate and adjust due to the movement of the fixing plate 333. When the movable plate 331 is in close contact with the fixing ring 320, When the ignition pin 300 is in the ignition pin body 200, the connecting plate 334 and the fixing plate 333 are in a vertical state. When installing, the fixing sleeve 300 on the outside of the ignition pin body 200 is inserted into the mounting hole of the mounting seat 110 from top to bottom. During the insertion process, the mounting hole will gradually squeeze the four rotating plates 335, so that the four rotating plates 335 deflect inward and shrink in the strip groove 311. As the rotating plates 335 deflect and shrink, the boss 3341 will also adapt to the rotation and push the fixing plate 333 upward. The boss 3341 slides along the groove When the fixing sleeve 300 is fully inserted into the mounting hole of the mounting seat 110, that is, the bottom surface of the fixing ring 320 is against the top surface of the mounting seat 110, the rotating plate 335 and the connecting plate 334 are no longer subjected to the squeezing force exerted by the mounting hole of the mounting seat 110. At this time, the spring 1 336 rebounds, driving the movable plate 331 to move downward again, so that the connecting plate 334 presses the rotating plate 335 to deflect outward, and the four connecting plates 334 return to their original positions. In the horizontal state, it is positioned on the mounting base 110 together with the fixing ring 320; when the ignition needle body 200 needs to be removed, press the annular sleeve 340 and push the ear plate 332 upward to move the movable plate 331 upward, and the spring 1 336 is thereby contracted. As the movable plate 331 moves upward, the fixing plate 333 moves upward synchronously to stretch the connecting plate 334, so that the angle between the connecting plate 334 and the rotating plate 335 is flattened. At this time, the fixing sleeve 300 can be directly and quickly pulled out together with the ignition needle body 200.

[0020] like Figure 7-8 As shown, in this embodiment, the opposing side walls of the two engaging blocks 341 are fixedly connected to spring 2 342. Two round rods 343 are also fixedly connected to the opposing side walls of the two engaging blocks 341. The other ends of the two round rods 343 extend through the outer wall of the annular sleeve 340 and are fixedly connected to a pull ring 344. The adjacent corners on the top surface of the two engaging blocks 341 are both rounded. The upper edges of the engaging groove 210 are also rounded.

[0021] In this embodiment, the corners of the clamping block 341 located on the top surface are provided with chamfers, and the edge of the clamping groove 210 located above is provided with chamfers. This design plays a guiding role in installing the fixing sleeve 300. When the ignition needle body 200 is inserted into the fixing sleeve 300 from top to bottom, the chamfers can make it easier for the clamping block 341 to contact and slide smoothly with the outer wall of the ignition needle body 200, reducing the resistance during the installation process and making the installation smoother. When the clamping block 341 is gradually clamped with the installation of the fixing sleeve 300, When the clamping block 341 is engaged with the clamping groove 210 at different heights, the rounded corners can guide the clamping block 341 to enter the clamping groove 210 more accurately; by clamping the clamping block 341 with the clamping grooves 210 at different heights, the installation height of the ignition needle body 200 can be changed. When the ignition needle body 200 and the fixing sleeve 300 need to be separated, the two pull rings 344 are pulled outward to make the two clamping blocks 341 shrink into the corresponding cavities respectively, so that the clamping block 341 is no longer engaged with the clamping groove 210. At this time, the ignition needle body 200 can be pulled out from the fixing sleeve 300.

[0022] like Figure 5 As shown, in this embodiment, the bottoms of the four strip-shaped grooves 311 are all provided with an outward inclination angle for limiting the unfolding angle of the rotating plate 335 .

[0023] When the locking cam 331 is in the unlock position, the locking cam 331 is in the unlock position, and the winch 330 is locked, so that the winch 330 can be unlocked easily.

[0024] like Figure 1 and Figure 4 As shown, in this embodiment, a magnet 322 is provided on the bottom surface of the fixing ring 320, and the metal ring 120 is detachably fixed to the top surface of the mounting seat 110 where the mounting hole is located by screws.

[0025] In specific implementation, when the fixing sleeve 300 with the ignition pin body 200 is inserted into the mounting hole of the mounting seat 110, the magnetic attraction of the magnet 322 arranged on the bottom surface of the fixing ring 320 can provide additional connection force between the fixing sleeve 300 and the mounting seat 110, thereby enhancing the stability of the connection between the two. Especially during the use of the stove, it may be subjected to vibration, external force impact, etc. The adsorption effect of the magnet 322 on the metal ring 120 can effectively prevent the fixing sleeve 300 from loosening or falling off, thereby ensuring the normal operation of the ignition pin body 200.
