[0037] This utility model discloses an electrical box, such as Figures 1 to 6As shown, the electrical box includes an outer casing 11, a door panel 12, and a first high-voltage drive board 13, a second high-voltage drive board 14, a first high-voltage transformer 15, a second high-voltage transformer 16, a control component, and a switching power supply 18 disposed within the outer casing 11. The outer casing 11 is hollow, and one side of the outer casing 11 has an opening. One edge of the door panel 12 is rotatably connected to the inner wall of the opening side. Both the outer casing 11 and the door panel 12 have heat dissipation holes 111. An insulating panel 112 is provided on the top surface of the outer casing 11, and a male and female connector 113 is fixedly disposed on the insulating panel 112. A first fan 114 is disposed on the bottom surface of the internal cavity of the outer casing 11, and the control component is disposed above the first fan 114 and is fixedly mounted on the inner side wall of the outer casing 11 opposite to the door panel 12. The first high-voltage transformer 15 and the door panel 16 are also disposed within the outer casing 11. The second high-voltage transformer 16 is disposed above the control component and fixedly mounted on the inner side wall of the electrical box housing 11 opposite to the door panel 12; the first high-voltage drive plate 13 is disposed on one side of the first high-voltage transformer 15 and fixedly mounted on the inner side wall of the electrical box housing 11 opposite to the door panel 12; the second high-voltage drive plate 14 is disposed on one side of the second high-voltage transformer 16 and fixedly mounted on the inner side wall of the electrical box housing 11 opposite to the door panel 12; the switching power supply 18 is disposed on another inner side wall of the electrical box housing 11 near the control component; the control component includes a circuit breaker 171, a PLC controller 174, an intermediate relay 175, a ground terminal block 172, and a terminal block 173; a power plug 115 is provided on the outer side wall of the electrical box housing 11, and the power plug 115 is electrically connected to the ground terminal block 172 and the terminal block 173.

[0038] The electrical connections and working principles between the electrical components can be found in the invention patent application number 202311147176.5. The door panel 12 covers the opening of the electrical box housing 11, thereby forming an internal cavity inside the electrical box housing 11. The specific structure is as follows... Figure 1 As shown. Among them, as Figure 4 and Figure 5As shown, the electrical components on the electrical mounting plate 17 are used to realize mains power access and circuit control. The first high-voltage drive board 13 drives the first high-voltage transformer 15 to generate a very high voltage, and the second high-voltage drive board 14 drives the second high-voltage transformer 16 to generate another very high voltage. The two high voltages are output through the male and female connectors 113 respectively. The first fan 114 is set on the bottom surface of the internal cavity in the electrical box housing 11, so the first fan 114 can deliver the gas in the internal cavity downward, thereby realizing heat dissipation for the various electrical components installed in the electrical box housing 11. Since the first high-voltage drive board 13, the second high-voltage drive board 14, the first high-voltage transformer 15, and the second high-voltage transformer 16 are all set above the internal cavity, and the electrical mounting plate 17 and the switching power supply 18 are each set separately on the side wall below the internal cavity (e.g., Figure 6 As shown in the figure, this can isolate the functional modules from each other, avoid interference between the functional modules during operation, and thus provide reasonable space between the electrical components to improve the isolation. This ensures efficient heat dissipation while preventing circuit failures in the ignition device, greatly improving the safety and reliability of the ignition device.

[0039] In a more specific embodiment, such as Figure 4 As shown, the electrical box also includes a second fan 116, which is disposed on the side of the door panel 12 facing the electrical box housing 11. The second fan 116 is positioned towards the first high-voltage transformer 15 and the second high-voltage transformer 16. Furthermore, to improve heat dissipation efficiency, a second fan 116 can be installed inside the electrical box; the second fan 116 can be disposed on the side of the door panel 12 facing the electrical box housing 11, and can be positioned towards the first high-voltage transformer 15 and the second high-voltage transformer 16, thus dissipating the heat generated by the first high-voltage transformer 15 and the second high-voltage transformer 16. The line output from the first high-voltage transformer 15 and the second high-voltage transformer 16 to the male-female connector 113 is high-voltage and low-current.

[0040] The electrical box casing 11 has perforated heat dissipation holes 111 around its perimeter, which improves heat dissipation, enhances safety, and extends the service life of components.

[0041] In a more specific embodiment, such as Figure 5 and Figure 6As shown, the circuit breaker 171, the grounding terminal block 172, and the terminal block 173 are mounted on the electrical mounting plate 17; the PLC controller 174 and the intermediate relays 175 are both mounted on the terminal block 173; the electrical mounting plate 17 is fixedly mounted on the inner wall of the electrical box housing 11 opposite to the door panel 12. Specifically, the circuit breaker 171 is located above the terminal block 173, and the grounding terminal block 172 is located on one side of the circuit breaker 171; the PLC controller 174 and the intermediate relays 175 are mounted side-by-side on the terminal block 173. Three intermediate relays 175 are mounted side-by-side on the terminal block 173.

[0042] Furthermore, a circuit breaker 171, a grounding terminal block 172, and a terminal block 173 can be installed on the electrical mounting plate 17. The terminal block 173 is located below the circuit breaker 171, and the grounding terminal block 172 is located on one side of the circuit breaker 171. The power plug 115 is electrically connected to the grounding terminal block 172 and the terminal block 173 to enable mains power access. Furthermore, a PLC controller 174 and an intermediate relay 175 can be mounted side-by-side on the terminal block 173, as shown in the specific structure below. Figure 5 As shown. Furthermore, since a three-phase AC mains power supply is required, three intermediate relays 175 can be installed, which are mounted side by side on the terminal block 173. A ground wire external screw hole 118 is provided on the side of the electrical box housing 11, and the ground wire external screw hole 118 is electrically connected to the ground wire terminal block 172.

[0043] In a more specific embodiment, a fixing bracket 117 is provided on the outer side of the electrical box housing 11 adjacent to the opening. Specifically, two parallel fixing brackets 117 are provided on each of the two outer side surfaces adjacent to the opening; the long side direction of each fixing bracket 117 is parallel to the insulating panel 112. Further, as... Figure 2 and Figure 3 As shown, to facilitate the fixed installation of the electrical box housing 11, a fixing bracket 117 can be provided on the outer side of the electrical box housing 11 adjacent to the opening. For example, fixing brackets 117 can be provided on the left and right outer sides adjacent to the opening respectively; two parallel fixing brackets 117 can be provided on each outer side, and the long side direction of the fixing brackets 117 is parallel to the plane where the insulating panel 112 is located, so that the electrical box housing 11 can be fixedly installed.

[0044] In a more specific embodiment, the outer wall of the electrical box housing 11 is further provided with a ground wire external screw hole 118, which is electrically connected to the terminal block 173. A door lock 121 is provided on the side of the door panel 12 away from the rotating connection.

[0045] Furthermore, to improve the reliability of the electrical connection, a grounding external screw hole 118 can be provided on the outer wall. The grounding external screw hole 118 is electrically connected to both the grounding terminal block 172 and the grounding plug on the insulating panel 112. Thus, the grounding terminal block 172 and the grounding plug can be electrically connected through the grounding external screw hole 118, thereby achieving grounding connection for the grounding plug. A door lock 121 can be provided on one side of the door panel 12, with the specific structure as follows... Figure 1 As shown.

[0046] This utility model also discloses an ignition device, such as Figure 7 As shown, the ignition device includes a housing 22, an ignition assembly 23, and an electrical box as described in the first aspect above. The housing 22 has a hollow cavity, and the electrical box is mounted on the lower part of the hollow cavity. The outer wall of the housing 22 has multiple ignition through holes 25 communicating with the upper part of the hollow cavity. The ignition assembly 23 is fixedly mounted on the top surface of the electrical box. A button 21 is located below the ignition through holes 25 on the outer wall of the housing 22. The side wall of the housing 22 has multiple vent holes. The ignition assembly 23 includes multiple sets of ignition needles 231, each set consisting of two ignition needles 231. Each ignition needle 231 in the ignition assembly 23 is electrically connected to a male-female connector 113. The axial direction of each ignition needle 231 is parallel to the vertical direction.

[0047] Specifically, each ignition needle 231 is connected to a male-female connector 113. The electrical components inside the electrical box generate a high voltage, which is applied to the two ignition needles 231 within a set of ignition needles 231. This creates a high-voltage arc between the ignition needles 231, igniting the air. The user can then insert a candle through the ignition hole 25 above the working set of ignition needles 231 to light the candle. Simultaneously, the electrical components inside the electrical box can switch between sets of ignition needles 231, preventing the same set of ignition needles 231 from remaining at a high temperature for an extended period due to maintaining a high-voltage arc. The electrical box is installed at the lower part of the hollow cavity, thus forming the ignition chamber 2 at the upper part of the hollow cavity. Ignition through holes 25 are all connected to the ignition chamber 2. The insulating panel 112 separates the upper ignition chamber 2 from the electrical components in the lower electrical box, thereby achieving safe isolation and improving safety. The fixing base 232 is fixedly installed on the insulating panel 112, and each set of ignition needles 231 is fixedly installed in the central recess of the fixing base 232, so that the electrical components and the ignition assembly 23 are respectively located in different areas, improving the safety of the ignition device. The specific structure is as follows: Figure 9 As shown.

[0048] Because multiple sets of ignition needles 231 need to be switched, the ignition assembly 23 contains at least two sets of ignition needles 231, and each set of ignition needles 231 consists of two ignition needles 231. The specific structure of the ignition assembly 23 is as follows: Figure 9 As shown. Button 21 is used to send an ignition control signal to the electrical components, so that the electrical components control the switching operation of each group of ignition needles 231 according to the ignition control signal. Button 21 is located on the lower side of the ignition through hole 25, which facilitates user use and avoids danger during use, thereby improving the safety of the device. Furthermore, the end of the ignition through hole 25 facing the inside of the ignition chamber 2 can be set to tilt upward. When the user inserts the incense stick into the ignition chamber 2, the end of the incense stick held by the user will inevitably rise with the tilt direction of the ignition through hole 25, thereby improving the efficiency of incense burning and preventing the incense stick from going out after being lit, thus improving the use effect.

[0049] In a typical design structure, the button 21 can be configured to consist of an on control button and an off control button. When the user presses the on control button, the electrical components control a set of ignition needles 231 to maintain high voltage and generate a high-voltage arc for a certain duration (e.g., 15 seconds, 20 seconds, or 30 seconds). After that, the electrical components control the currently working set of ignition needles 231 to de-energize and control another set of ignition needles 231 to maintain high voltage and generate a high-voltage arc for a certain duration (e.g., 15 seconds, 20 seconds, or 30 seconds). This switching control step of each set of ignition needles 231 is continuously cycled until the control signal corresponding to the user pressing the off control button is received. If the user presses the off control button, the electrical components control the currently working set of ignition needles 231 to extinguish, thereby ending the ignition operation process.

[0050] In a more specific embodiment, such as Figure 7 As shown, the outer wall of the ignition chamber 2 has a cubic structure, and each of the multiple outer walls on the side of the ignition chamber 2 has a corresponding ignition through hole 25. Specifically, the ignition through hole 25 is circular, elliptical, or polygonal.

[0051] The outer wall of the ignition chamber 2 can be configured as a cube structure, and multiple ignition through holes 25 can be provided on the multiple outer walls of the ignition chamber 2, so that one ignition through hole 25 can be provided on each outer wall. In a typical design structure, three ignition through holes 25 can be provided on each of the three outer walls of the ignition chamber. The shape of the ignition through hole 25 can be circular, elliptical, or polygonal, and the polygon can be rectangular, rhomboid, pentagonal, triangular, etc.

[0052] In a more specific embodiment, a top plate 221 is provided on the housing. The top plate 221 is composed of four sets of inclined plates, each set of inclined plates corresponding to one side of the ignition chamber 2. The outer edge of each set of inclined plates is inclined downward and extends outward to the outside of the ignition chamber 2. The joints of the connected inclined plates form an upwardly raised keel 222, and the top corners of the outer side of the keel 222 are all upturned.

[0053] The top plate 221 can be configured to consist of four sets of inclined plates, each set of inclined plates corresponding to one side of the ignition chamber 2, such as... Figure 1 and Figure 2 As shown, the outer edge of each set of inclined plates is inclined downwards, which facilitates the drainage of falling rainwater. The outer edge of each set of inclined plates extends outwards from the ignition chamber 2, so that the top plate 221 can cover a larger area and prevent rainwater from splashing into the interior of the ignition chamber 2.

[0054] Furthermore, to improve the effectiveness of rainwater diversion and discharge, a raised keel 222 can be set at the connection of the inclined plates. The keel 222 can divide the four inclined plates, and the top corners of the outer side of the keel 222 are all raised upwards, thereby further improving the rainproof effect.

[0055] Specifically, ventilation holes can be provided on the side plate 12 connected to the side door panel of the base 1 to further improve heat dissipation. Furthermore, to enhance the waterproof performance of the ventilation holes, an arc-shaped baffle 241 can be installed above each ventilation hole. Each ventilation hole is equipped with an arc-shaped baffle 241, which is higher in the middle and lower on both sides, forming an arch shape. The arc-shaped baffle 241 is located on the outer surface of the side plate 12 of the base 1. When rainwater falls onto the arc-shaped baffle 241, it can be discharged downwards from both sides of the baffle 241, thereby improving the waterproof performance of the ventilation holes and thus enhancing the reliability of the ignition device.

[0056] In another embodiment, the external structure of the ignition device may also be configured as follows: Figure 8 As shown, a top plate 221 is provided on the housing. The top plate 221 is composed of four sets of inclined plates. Each set of inclined plates corresponds to one side of the ignition chamber 2. The top plate of the ignition device is not provided with a keel, and there is no upward tilt at each of the top corners. Figure 8 The ignition device shown has a base 26 with sloping sides at the bottom to improve its anti-tipping ability and increase the stability of the ignition device; apart from this, the other parts are the same as... Figure 7 The ignition devices shown are the same.

[0057] This utility model discloses an ignition device and its electrical box. The electrical box includes an outer casing, a door panel, and a first high-voltage drive board, a second high-voltage drive board, a first high-voltage transformer, a second high-voltage transformer, a control component, and a switching power supply disposed within the outer casing. The outer casing is hollow, with an opening on one side. One edge of the door panel is rotatably connected to the inner wall of the opening side. Both the outer casing and the door panel have heat dissipation holes. An insulating panel is provided on the top surface of the outer casing, and a male and female connector is fixedly mounted on the insulating panel. A first fan is disposed on the bottom surface of the internal cavity of the outer casing, and the control component is disposed above the first fan. By rationally arranging the assembly positions of the electrical components, the above-mentioned electrical box achieves efficient heat dissipation for the internally assembled electrical components and provides reasonable space between the electrical components to improve isolation. This ensures efficient heat dissipation while preventing circuit failures in the ignition device, greatly improving the safety and reliability of the ignition device.

[0058] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
