In another embodiment, based on the structural optimization of the relevant parts of the ignition assembly 100, the bracket member 200 can be omitted, so that the ignition assembly 100 can be formed into a single body or a complete whole after being combined and formed, and thus can be directly used as an inner core for assembly and application or disassembly and maintenance.

Referring to fig. 1 to 4, a gun housing 300 is an outer shell of the ignition gun, and plays a role of receiving and protecting an inner core; the gun housing 300 is of an integral tube structure, and can be integrally formed by different processes according to the material difference of the gun housing 300, for example, the gun housing can be integrally formed by plastic materials through injection molding, 3D printing and other process means, and can be integrally formed by metal materials through machining, 3D printing and other process means.

In one embodiment, referring to fig. 4, the gun housing 300 is a double-ended integral tube structure, i.e., based on the structural configuration of the gun housing 300, it should have two ports oppositely disposed along its length, for convenience of description, one of the ports is defined as a first port 310, and the other port is defined as a second port 320; the first port 310 is mainly used for inserting the core into the gun housing 300 along the length direction of the gun housing 300 and assembling the core into the gun housing 300 to provide a structural passage, and the second port 320 mainly plays a role of limiting the core in the gun housing 300 and allows the ignition end of the core to pass through and be exposed out of the end side of the gun housing 300, so that the ignition end can ignite outside the gun housing 300; in specific implementation, the first port 310 may be configured with a relevant size and shape according to the overall external profile shape and size of the core, so that the core can be inserted into the gun case 300, and the second port 320 may be selectively configured according to the size and shape of the firing end, for example, configured as a semi-closed structure or subjected to necking treatment, so as to prevent the core from passing out of the gun case 300 through the second port 320; in this embodiment, first port 310 can be closed or plugged with a mating end cap after gun shell 300 is inserted into gun shell 300 to removably enclose the core within gun shell 300.

Meanwhile, an operation port 330 is penetratingly provided at a circumferential side wall of the gun housing 300 to provide a space for structural assembly of the ignition switch 400 or performing a switching action; the ignition switch 400 mainly plays a role in controlling the inner core to start or close the ignition function by an operator, and can be a conventional plate-shaped object with a press or touch switch, and establish an electrical connection relationship with the inner core (specifically, a relevant function part playing a discharging function and an air discharging function in the ignition assembly 100) through wires such as a connecting wire, and the switch distribution of the ignition switch 400 can be exposed on the circumferential surface of the gun case 300 by using the operation port 330, so that the operator can directly press or touch the ignition switch 400; the ignition switch 400 may also be only one action executing component, and a corresponding linkage mechanism is disposed in the inner core (specifically, the ignition assembly 100), and the movement of the linkage mechanism is utilized to directly start the functional components of the inner core to discharge or simultaneously deflate, at this time, the ignition switch 400 may be directly and fixedly connected with the linkage mechanism, so as to establish a linkage connection relationship between the ignition switch 400 and the inner core, and at the same time, the ignition switch 400 is exposed on the circumferential surface of the gun case 300 through the operation port 330, so that an operator can control the movement of the linkage mechanism through the ignition switch 400, thereby triggering the ignition of the inner core.

In one embodiment, referring to fig. 2, 3 and 4, the ignition assembly 100 includes a pilot assembly 110 having a firing end, a fuel reservoir assembly 120 for storing and supplying fuel to the firing end, and a piezoelectric assembly 130 for discharging the fuel to the firing end.

The sump assembly 120 includes a fuel container and an air outlet valve; wherein, the fuel container is used for storing fuel, and can be arranged into a bottle-shaped or barrel-shaped structure according to the internal structure of the inner core or the gun housing 300, the air outlet valve is used as a valve of the fuel container, and is arranged on the fuel outlet or the fuel output pipeline of the fuel container, so that the fuel in the fuel container can release the fuel to the outside through the air outlet valve after the air outlet valve is opened; based on the difference in the connection relationship between the ignition switch 400 and the ignition module, when the ignition switch 400 and the ignition module are electrically connected, the gas outlet valve may be an electric valve such as an electromagnetic valve; when the ignition switch 400 is linked with the ignition component, the air outlet valve can be a mechanical valve, which is not described herein as the prior art.

The ignition assembly 110 may be constructed by an ignition nozzle or an ignition needle of an existing ignition gun, one end of which is exposed to the end surface of the gun housing 300 through the second port 320 to serve as an ignition head, and the other end of which is connected to the oil tank assembly 120 through a fuel pipeline (for example, connected to a fuel container through an air outlet valve), so that after the oil tank assembly 120 is opened, fuel can be delivered to the ignition assembly 110 and finally ejected through the ignition end; meanwhile, the ignition assembly 110 is connected to the piezoelectric assembly 130, so that the piezoelectric assembly 130 can discharge electricity to the ignition assembly 110 (especially, the ignition end), thereby igniting the fuel provided by the fuel tank assembly 120 to achieve the ignition function of the inner core.

The piezoelectric component 130 can be formed by combining, connecting and molding functional components such as a power supply, a high-voltage pack, an arc generating head, a discharge component (such as a discharge control board), a discharge switch and the like; the discharge switch of the piezoelectric element 130 may be defined as the piezoelectric switch 131 of the piezoelectric element 130, and the other functional elements may be collectively defined as the main body 132 of the piezoelectric element 130; the piezoelectric switch 131 is disposed in or connected to the discharge circuit of the main body 132 to start or stop the discharge function of the main body 132, and the main body 132 is electrically connected to the ignition element 110, so that the generated current can be transmitted to the ignition element 110, and the ignition element 110 is equivalent to the spark discharge end of the piezoelectric element 130 to ignite the fuel at the ignition end; the piezoelectric switch 131 may be an electronic switch or a mechanical switch, based on the same type selection requirement as the gas outlet valve of the oil sump assembly 120.

Based on this, the ignition switch 400 is respectively electrically connected or linked with the air outlet valve of the oil tank assembly 120 and the piezoelectric switch 131 of the piezoelectric assembly 130, so that the ignition switch 400 can be used for controlling the synchronous start or stop of the oil tank assembly 120 and the piezoelectric assembly 130; for example, during synchronous start-up, fuel provided by the sump assembly 120 is delivered to the firing end of the pilot assembly 110, while the spark generated by the piezoelectric assembly 130 is simultaneously delivered to the firing end of the pilot assembly 110, thereby igniting the fuel; conversely, the oil sump assembly 120 and the piezoelectric assembly 130 may be synchronously turned off to ultimately turn off the firing function of the firing gun.

In another embodiment, the oil groove assembly 120 may be omitted, so that the ignition gun only has a function of generating an electric spark through the ignition end of the ignition assembly 110 to be used as an igniter, and when the ignition gun is applied to a scene such as ignition of a gas stove, the ignition end of the inner core may be placed at a gas outlet of the gas stove, and the electric spark generated by the ignition end may be used to ignite gas.

In one embodiment, referring to fig. 2 to 4, the ignition assembly 100 further includes a linkage assembly 140 disposed between the oil bath assembly 120 and the piezoelectric assembly 130, for example, mounted on the support member 200 along the length direction of the gun housing 300 and located between the gas outlet valve and the piezoelectric switch 131, and mainly used for synchronously triggering the two trigger members to operate in a mechanical linkage (or movement) manner, so as to synchronously open or close the oil bath assembly 120 and the piezoelectric assembly 130; it is understood that in this embodiment, the air outlet valve may be a mechanical valve, the piezoelectric switch 131 may be a mechanical switch, and the ignition switch 400 is connected to the linkage assembly 140, so that an operator can operate the ignition switch 400 to actuate the linkage assembly 140, the air outlet valve and the piezoelectric switch 131 to perform linkage action.

The movable push plate 142 is mounted on the holder 200 so as to be capable of reciprocating in the longitudinal direction of the gun housing 300, and the ignition switch 400 also has a characteristic of reciprocating in the longitudinal direction of the gun housing 300 based on the connection relationship between the ignition switch 400 and the movable push plate 142, so that the shape and size of the operation hole 330 need to be adapted to the movement trajectory of the ignition switch 400.

The oil groove prying plate 141 may be made of a material having a certain reversible deformation, and is substantially of a bent structure, for example, the oil groove prying plate 141 includes a connecting section having a structure shape similar to an L shape and a buckling section formed by bending or bending and extending one end of the connecting section, the oil groove prying plate 141 is in contact with or connected to the bracket member 200 in an abutting manner, and at this time, a portion of the oil groove prying plate 141 in contact with the bracket member 200 may be defined as a fulcrum of the oil groove prying plate 141. In specific implementation, the connecting end of the oil groove pry plate 141 can be connected with the gas outlet valve of the oil groove assembly 120, and the warping section is in abutting contact with the moving push plate 142; when the ignition switch 400 drives the moving push plate 142 to move towards the piezoelectric switch 131, the oil groove pry plate 141 rotates or deforms around the fulcrum thereof relative to the support member 200, so as to open the oil groove assembly 120, and further, the fuel in the fuel container is conveyed to the ignition end by utilizing the communication relationship between the oil groove pry plate and the ignition assembly 110; otherwise, the fuel container may be closed.

The piezoelectric lever 143 may also be a bent structure, one end of which is rotatably connected to the support member 200, and the other end of which is disposed between the movable push plate 142 and the piezoelectric switch 131; in this case, the piezoelectric switch 131 may adopt an existing electronic component such as a piezoelectric switch; when the moving push plate 142 moves towards the piezoelectric switch 131, the piezoelectric lever 143 can be pushed to rotate relative to the support member 200, and finally a pressing action force is applied to the piezoelectric switch 131 through the end of the piezoelectric lever 143, so that the piezoelectric switch 131 is triggered to conduct a discharge circuit of the main body portion 132, a discharge current is transmitted to an ignition end by utilizing an electrical connection relationship between the main body portion 132 and the ignition assembly 110, and further, fuel transmitted to the ignition end is ignited finally, and an ignition function of inner core linkage action is realized.

In summary, the oil groove pry plate 141, the movable push plate 142 and the piezoelectric lever 143 are cooperatively engaged, which is equivalent to constructing a lever-type linkage mechanism on the ignition assembly 100 or the bracket member 200, so that an operator can start or close the ignition function of the inner core by pushing the ignition switch 400 to reciprocate more smoothly and laborsavingly based on the action principle of the lever-type structure, and the comfort of the ignition gun operation is effectively improved.
