[0047] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] See Figures 1 to 7 , in an embodiment of the present invention, a waterproof arc generator assembly 100 is provided, including a fixing plate 10 and at least one arc generator 20:

[0049] The fixing plate 10 is provided with at least one convex platform 11 protruding upward; the inside of the convex platform 11 is a ventilation duct 111 that penetrates longitudinally and penetrates the fixing plate 10;

[0050] The arc generator 20 includes:

[0051] An outer metal ring 21, located in the ventilation duct 111 and connected to the upper part of the convex platform 11;

[0052] An ion needle 22, located in the ventilation duct 111; the ion needle 22 is connected to the convex platform 11 through an insulating member;

[0053] An inner metal ring 23, located in the ventilation duct 111 and sleeved on the outside of the upper part of the ion needle 22; the inner metal ring 23 is located inside the outer metal ring 21, and there is a gap between the outer side surface of the inner metal ring 23 and the inner side surface of the outer metal ring 21;

[0054] The insulating spacer 24 covers the top of the inner metal ring 23; the cross-section of the insulating spacer 24 is greater than or equal to the cross-section of the ventilation duct 111; the insulating spacer 24 is located above the outer metal ring 21, and an air outlet space 1111 of the ventilation duct 111 is formed between the insulating spacer 24 and the outer metal ring 21.

[0055] In this embodiment, the waterproof arc generator assembly 100 can be applied to a waterproof arc heating furnace 200, and the heat of the arc generated by it can heat a heating body such as a cooking utensil. The setting of the fixing plate 10 facilitates the installation of the arc generator 20 and can protect the arc generator 20. The fixing plate 10 is provided with a convex platform 11 protruding upward, and the arc generator 20 is connected inside the convex platform 11. Thus, the convex platform 11 can protect the arc generator 20 inside it and reduce the entry of water or foreign objects. A through ventilation duct 111 is formed inside the convex platform 11, and the arc of the arc generator 20 is generated inside the ventilation duct 111. The heat generated by the arc can be dissipated through the ventilation duct 111. The ventilation duct 111 also penetrates the fixing plate 10, and the components located below the fixing plate 10 can also communicate with the ventilation duct 111. When powered on, the arc generator 20 generates an arc, and the arc can generate a high temperature of over 1000 degrees Celsius. The outer metal ring 21 and the inner metal ring 23 of the arc generator 20 are separated. The structure is simple and convenient for production. Optionally, the outer metal ring 21 is made of a tungsten alloy material, and the inner metal ring 23 is made of a tungsten alloy material, so that the produced outer metal ring 21 and inner metal ring 23 are small in volume and low in cost. The outer metal ring 21 is arranged on the upper part of the convex platform 11, and the inner metal ring 23 is located inside the outer metal ring 21. Optionally, the first metal ring and the second metal ring are coaxially arranged. Since there is a spacing between the outer side surface of the inner metal ring 23 and the inner side surface of the outer metal ring 21, and the spacing is within a preset range, a ring-shaped space with a suitable size is formed between the first metal ring and the second metal ring. The arc is generated in the ring-shaped space between the inner metal ring 23 and the outer metal ring 21. The position of the arc is located on the upper part of the convex platform 11, and the heat generated by the arc dissipates upward. When powered on, the outer metal ring 21 is connected to a first power source, and the inner metal ring 23 is connected to a second power source through an ion needle 22. Optionally, the ion needle 22 is made of a metal material; the inner metal ring 23 is also connected to the convex platform 11 through the ion needle 22. Since the outer metal ring 21 and the inner metal ring 23 are respectively connected to two power sources, the ion needle 22 is connected to the convex platform 11 through an insulating member. The insulating isolation sheet 24 covers the top end of the inner metal ring 23. The top surface of the insulating isolation sheet 24 is the topmost surface of the arc generator 20, and the projection of the insulating isolation sheet 24 in the cross-section can cover the ventilation duct 111, thereby blocking the entry of water or foreign objects into the ventilation duct 111, and can also block the touch of the user or the cooking utensil to avoid electric shock. Optionally, the insulating isolation sheet 24 is made of a ceramic material. The insulating isolation sheet 24 is located above the outer metal ring 21, and an air outlet space 1111 of the ventilation duct 111 is formed between the insulating isolation sheet 24 and the outer metal ring 21, so that the heat generated by the arc can dissipate upward from the ventilation duct 111. The air outlet space 1111 is annular, that is, the heat generated by the arc can dissipate upward to the surrounding, increasing the heating area of the heating body (such as a cooking utensil) to make the heating more uniform.

[0056] See Figures 8 to 9, As an optional embodiment, the arc generator 20 further includes a rotary air generator 25, which is connected to the lower part of the boss 11; a first through hole 2521 adapted to the ion needle 22 is provided inside the rotary air generator 25, and the upper part of the ion needle 22 passes through the first through hole 2521 and extends into the ventilation duct 111; the connection part between the rotary air generator 25 and the ion needle 22 is an insulating layer;

[0057] The ventilation duct 111 is located on the air outlet side of the rotary air generator 25.

[0058] In this embodiment, the rotary air generator 25 can generate rotary air. Since the ventilation duct 111 is located on the air outlet side of the rotary air generator 25, the generated rotary air blows into the ventilation duct 111. Since the arc is an electric ion with light mass, the rotary air can make the arc in the ventilation duct 111 rotate under the blowing of the rotary air. Due to the action of the rotary air, the heat of the arc can also be dissipated from the air outlet space 1111. The rotary air generator 25 can also be an insulating connection member between the ion needle 22 and the boss 11. Optionally, the entire rotary air generator 25 is made of insulating material.

[0059] See Figures 8 to 9 , As an optional embodiment, the rotary air generator 25 includes: an outer cylinder 251, an inner cylinder 252 and a plurality of air guiding vanes 254; the outer cylinder 251 has a hollow structure and is located outside the inner cylinder 252; the outer cylinder 251 and the inner cylinder 252 are coaxially arranged; a wind guiding space 253 is formed between the outer cylinder 251 and the inner cylinder 252; the plurality of air guiding vanes 254 are sequentially arranged in the wind guiding space 253 along the circumferential direction of the inner cylinder 252; one end of each air guiding vane 254 in the radial direction of the inner cylinder 252 is connected to the outer side surface of the inner cylinder 252, and the other end is connected to the inner side surface of the outer cylinder 251; one end of each air guiding vane 254 in the circumferential direction of the inner cylinder 252 extends obliquely towards the other end; an air inlet 255 is formed between two adjacent air guiding vanes 254;

[0060] The inside of the inner cylinder 252 is the first through hole 2521.

[0061] In this embodiment, the wind enters the air guiding space 253 from the air inlet side of the rotating wind generator 25 through the air inlet 255. Due to the restrictive effects of the inner cylinder 252, the outer cylinder 251, and the air guiding vanes 254, the wind rotates along the circumferential direction of the inner cylinder 252 within the air guiding space 253. While rotating, the wind climbs upward along the air guiding vanes 254 that are inclined and extend circumferentially, and is blown into the ventilation duct 111 through the air outlet side of the rotating wind generator 25, forming a rotating wind within the ventilation duct 111 to blow the arc within the ventilation duct 111 to rotate, preventing the arc from continuously staying at the same position and increasing the service life of the arc generator 20. Since the air guiding vanes 254 are fixed between the inner cylinder 252 and the outer cylinder 251, the generated rotating wind is stable, and the structure of this rotating wind generator 25 is simple, facilitating processing and production.

[0062] As an alternative embodiment, the fixing plate 10 and the boss 11 are integrally formed to avoid the generation of gaps and reduce the possibility of water ingress.

[0063] See Figure 1 and Figure 4 , as an alternative embodiment, the outer metal ring 21 is circular; the top end of the outer metal ring 21 is provided with a flange 211 that protrudes outward in a circle; the bottom surface of the flange 211 abuts against the top surface of the boss 11; the outer side surface of the flange 211 is an inclined surface that gradually inclines outward from top to bottom.

[0064] In this embodiment, since the outer metal ring 21 is within the ventilation duct 111 inside the boss 11, the setting of the flange 211 can cover the gap between the outer metal ring 21 and the boss 11, and when water flows onto the flange 211, it can also be diverted outward through the flange 211, reducing the possibility of water entering the arc generator 20 to prevent water from entering the waterproof arc heating furnace 200 through the arc generator.

[0065] See Figure 6 , as an alternative embodiment, the inner metal ring 23 is in the shape of an inverted frustum, and the cross-section of the inner metal ring 23 gradually increases from bottom to top; the lower part of the inner metal ring 23 is located within the outer metal ring 21, and its upper part extends out of the outer metal ring 21;

[0066] The inside of the inner metal ring 23 is a second through-hole 231 that is adapted to the ion needle 22, and it is sleeved on the outside of the upper part of the ion needle 22 through the second through-hole 231.

[0067] In this embodiment, the lower part of the inner metal ring 23 is located inside the outer metal ring 21, and the distance between the lower part of the inner metal ring 23 and the outer metal ring 21 is within a preset range to facilitate the generation of an electric arc. Its upper part extends out of the outer metal ring 21 and the cross-section of the upper part is larger than that of the lower part, which can reduce the space for water or foreign objects to enter and can reduce the possibility of water or foreign objects entering, so as to prevent water from entering the waterproof arc heating furnace 200 through the arc generator.

[0068] See Figures 1 to 3 , as an alternative embodiment, a plurality of arc generators 20 are provided, and a plurality of bosses 11 are correspondingly provided for the arc generators 20; the fixing plate 10 is made of a metal material; the bosses 11 are made of a metal material. When a plurality of arc generators 20 are provided, since the metal material can conduct electricity, the first power supply can be connected to the fixing plate 10 to conduct electricity to the outer metal rings 21 of the plurality of arc generators 20, simplifying the conductive structure. Optionally, the plurality of arc generators 20 are evenly distributed on the fixing plate 10.

[0075] In this embodiment, the waterproof arc heating furnace 200 can heat heat-receiving bodies such as cookware. When water or objects in the heat-receiving bodies such as cookware overflow, it can reduce the entry of water or foreign objects into the device accommodation space 214 and affect the service life. The waterproof arc generator assembly 100 is installed in the installation groove 2111. Since the installation groove 2111 is provided with a slot 2112 communicating with the device accommodation space 214, covering and installing the waterproof arc generator assembly 100 on the installation groove 2111 can reduce the possibility of water ingress. When the waterproof arc generator assembly 100 is energized and working, the generated arc can emit a high temperature above 1000 degrees Celsius, and the heat dissipated by the arc is used to heat the cookware.

When there are multiple arc generators 20 in the waterproof arc generator assembly 100, power supply through the second circuit board 230 can simplify the power supply structure, and the second circuit board 230 can realize simultaneous power supply to multiple ion needles 22. Whether each power circuit of the first circuit board 220 supplies power is controlled by the switch 240, and the user can operate the switch 240 to control it.
