The term "and / or" used in the specification includes any and all combinations of one or more related listed items.

[0024] Please refer to Figure 1 and Figure 2 The firing module 1000 includes a base 1 and a firing assembly 2, the firing assembly 2 is arranged in the base 1, and the firing assembly 2 is used to initiate combustion of fuel.

[0025] For the above-mentioned base 1, in some embodiments, please refer to Figure 2 and Figure 3The base 1 is provided with an ignition cavity 10 for placing fuel, so as to provide a combustion space for the fuel. The ignition assembly 2 is arranged on the base 1, and part of the ignition assembly 2 is arranged in the ignition cavity 10 for igniting the fuel in the ignition cavity 10.

[0026] In some embodiments, referring to Figure 2 and Figure 3 , the base 1 comprises a base body 11 and a clamping block 12, the base body 11 comprises an extension 112 and a main body 111, the main body 111 is connected to one end of the extension 112, and the ignition cavity 10 extends from the end of the extension 112 away from the main body to the main body 111. The main body 111 is provided with a notch 1110, and the clamping block 12 is arranged in the notch 1110 of the main body 111. Part of the ignition assembly 2 is located between the clamping block 12 and the main body 111. The clamping block 12 and the main body 111 are detachably connected. Separating the clamping block 12 from the main body 111 can quickly complete the installation and disassembly of the ignition assembly 2, thereby improving the installation efficiency and maintainability of the ignition module 1000.

[0027] In some embodiments, one of the main body 111 and the clamping block 12 is provided with a connecting column, and the other of the main body 111 and the clamping block 12 is provided with a connecting hole. The connecting column is inserted into the connecting hole to connect the main body 111 and the clamping block 12. This enhances the connection stability and facilitates the separation of the main body 111 and the clamping block 12. In an example, referring to Figs. 2 and Figure 4 , the clamping block 12 is provided with a connecting column 121 on the side facing the main body 111, and the main body 111 is provided with a connecting hole 1111 on the side facing the clamping block 12. The connecting column 121 is inserted into the connecting hole 1111.

[0028] In some embodiments, referring to Figure 2 and Figure 3 , the outer wall of the base 1 is provided with external threads 13. The external threads 13 are used for screwing with external components to connect the base 1 with the external components. In an example, the ignition module 1000 is arranged in a magazine. The shell of the magazine is provided with internal threads. The internal threads are screw-connected with the external threads 13 to fix the ignition module 1000 in the magazine.

[0029] In some embodiments, the external thread 13 comprises a first thread 131 and a second thread 132, the first thread 131 is arranged on the outer wall of the main body 111, and the second thread 132 is arranged on the outer wall of the clamping block 12.

When the external components are threadedly connected with the base 11, the external components can be simultaneously threadedly connected with the clamping block 12 and the main body 111, and the thread limiting of the main body 111 and the clamping block 12 by the external components further enhances the structural stability of the base 1.

[0030] For the above-mentioned ignition assembly 2, in some embodiments, referring to Figure 2 and Figure 3 , the ignition assembly 2 comprises a first electrode 21, a second electrode 22 and a fuse 23, the fuse 23 is electrically connected with one end of the first electrode 21 and one end of the second electrode 22 respectively, and the other end of the first electrode 21 and the other end of the second electrode 22 extend out of the base 1. The polarities of the first electrode 21 and the second electrode 22 are opposite, when the other end of the first electrode 21 and the other end of the second electrode 22 are connected with an external power supply, the current passes through the fuse 23, and the fuse 23 generates heat. The fuse 23 is at least partially located in the ignition cavity 10, and the fuse 23 is at least partially in direct contact with the fuel in the ignition cavity 10. When the ignition assembly 2 is powered on, the heat generated by the fuse 23 accumulates, so that when the temperature reaches the ignition point of the fuel, the fuel is ignited to achieve ignition.

[0031] In some embodiments, when the ignition assembly 2 is powered on, the temperature of the fuse 23 rapidly rises until it reaches its melting temperature, so that the fuse 23 is melted. The heat released in the melting moment is concentrated and strong, so that rapid ignition is achieved. At the same time, the melting of the fuse 23 interrupts the circuit, so that the ignition module 1000 is powered off after completing ignition, which improves safety.

[0032] In some embodiments, the other end of the first electrode 21 and the other end of the second electrode 22 are both electrically connected with an external low-voltage power supply. The fuse 23 can rapidly rise in temperature and reach the temperature required for igniting fuel under low-voltage conditions, so that low-voltage ignition is achieved. This not only improves the safety of the ignition module 1000, but also reduces energy consumption. In some examples, the external low-voltage power supply is a direct current power supply, and the voltage range is 3V to 12V.

[0033] In some embodiments, referring to Figure 5The ignition module 1000 further comprises an ignition circuit connected with the ignition assembly 2, and the ignition circuit is used for realizing low-voltage ignition and detecting whether the ignition assembly 2 is ignited. The ignition circuit comprises a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a first capacitor C1, a second capacitor C2, a third capacitor C3, a first power tube Q1, a second power tube Q2, a first driving chip U1 and a second driving chip U2. The first resistor R1 and the second resistor R2 are respectively a driving resistor and a pull-down resistor of the first power tube Q1. The third resistor R3 and the fourth resistor R4 are respectively a driving resistor and a pull-down resistor of the second power tube Q2. The fifth resistor R5 and the first capacitor C1 have a low-pass filtering effect. One end of the fifth resistor R5 and one end of the first capacitor C1 are both connected to an ADC (Analog-to-Digital Converter) interface of the single-chip microcomputer. The second capacitor C2 and the third capacitor C3 have a filtering effect respectively.

[0034] When the single-chip microcomputer sends a pulse width modulation signal PWM1 and PWM2 with a first time length to the first driving chip U1 and the second driving chip U2 through the ADC interface, the first driving chip U1 and the second driving chip U2 control the first power tube Q1 and the second power tube Q2 to be turned on respectively. At this time, the sixth resistor R6 is short-circuited, the current passing through the fuse 23 is greater than the rated current of the fuse 23, the fuse 23 is heated and fused in a short time, a large amount of heat is released, and then the fuel is ignited, so as to realize low-voltage ignition.

[0035] When the single-chip microcomputer sends a pulse width modulation signal PWM1 with a second time length to the first driving chip U1 through the ADC interface, the first driving chip U1 controls the first power tube Q1 to be turned on. At this time, a detection voltage signal is obtained at the voltage detection end VIN, and after being filtered through the fifth resistor R5 and the first capacitor C1, the detection voltage signal enters the ADC interface. The single-chip microcomputer judges whether the fuse 23 is fused according to the detection voltage, and further determines whether the ignition assembly 2 is ignited. The second time length is less than the first time length.

[0036] In some embodiments, the ignition module 1000 further comprises a circuit board (not shown in the figure), and the ignition circuit is arranged on the circuit board. The other end of the first electrode 21 and the other end of the second electrode 22 are both electrically connected with the circuit board. The ignition module 1000 is powered and communicates with the outside through the circuit board.

[0037] In some embodiments, referring to Figure 2 and Figure 3 The ignition assembly 2 further comprises a fixing member 24, and the first electrode 21 and the second electrode 22 are fixed to the fixing member 24, so as to enhance the structural strength of the ignition assembly 2. The main body part 111 is provided with a fixing groove 1112, and the fixing member 24 is arranged in the fixing groove 1112, so as to limit and fix the ignition assembly 2 to the base 1.

[0038] In some embodiments, the main body 111 is further provided with a first limiting slot 1113 and a second limiting slot 1114, which are respectively arranged on both sides of the ignition cavity 10. The two ends of the fuse 23 are respectively placed in the first limiting slot 1113 and the second limiting slot 1114, so that the fuse 23 is limited by the first limiting slot 1113 and the second limiting slot 1114, further enhancing the connection stability of the ignition assembly 2 and the base 1.

[0039] In some embodiments, referring to Figure 3 , the ignition cavity 10 includes a first cavity 101 and a second cavity 102 connected in communication, the first cavity 101 is located in the main body 111, the second cavity 102 is located in the extension 112, and the fuse 23 is at least partially located in the first cavity 101. The cross-sectional area of the first cavity 101 is smaller than that of the second cavity 102, so that the first cavity 101 provides a relatively narrow combustion space, which helps to concentrate the heat generated by the fuse 23, improves the combustion efficiency and the reliability of ignition. At the same time, the second cavity 102 located in the extension 112 provides accommodation and guiding space for the high-temperature and high-pressure gas generated when the fuel burns.

[0040] In some embodiments, referring to Figures 2 to 4 , the main body 111 is provided with a first recess 1115, and the clamping block 12 is provided with a second recess 122, and the first recess 1115 and the second recess 122 are relatively enclosed to form the first cavity 101.

[0041] In some embodiments, the clamping block 12 is further provided with recesses corresponding to the fixing slot 1112, the first limiting slot 1113 and the second limiting slot 1114 respectively, so that the main body 111 and the clamping block 12 enclose and limit the ignition assembly 2.

[0042] In some embodiments, referring to Figure 1 and Figure 2 , the base 1 further includes a sleeve 14, the sleeve 14 is sleeved on the extension 112, and the sleeve 14 is sleeved on the outside of the second cavity 102, so as to enhance the structural strength of the cavity wall of the ignition cavity 10 and improve the safety of the ignition module 1000. In some examples, the sleeve 14 is made of metal or alloy material.

[0043] In the embodiment of the present application, the ignition module 1000 comprises a base 1 and an ignition assembly 2, the base 1 is provided with an ignition cavity 10 for placing fuel, the ignition assembly 2 comprises a first electrode 21, a second electrode 22 and a fuse 23, the fuse 23 is connected with the first electrode 21 and the second electrode 22 respectively, and the fuse 23 is at least partially located in the ignition cavity 10. When the first electrode 21 and the second electrode 22 are connected with an external low-voltage power supply, the fuse 23 can rapidly heat up to ignite the fuel, so as to realize low-voltage ignition. The low-voltage ignition not only reduces energy consumption, but also reduces the risk of high-voltage breakdown and short circuit, and improves the safety of the ignition module 1000.

[0044] The present application provides a clip, which comprises a functional unit and the ignition module 1000 described above. The functional unit and the ignition module 1000 are arranged in a shell. The ignition module 1000 is used to provide power gas after igniting the fuel, so as to push the functional unit to be ejected from the shell. The structure and function of the ignition module 1000 can be referred to the above-described embodiments, which will not be described here.

[0045] In the embodiment of the present application, the clip realizes low-voltage ignition by the ignition module 1000, so as to improve the safety performance of the clip.
