[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] Furthermore, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Please see Figures 1-2 A waterproof structure for an electric flame stove includes: a rectifier circuit board 1 with a non-perforated area 11 and a perforated area 12 for drainage. The non-perforated area 11 includes an electronic component area 111 and several intermediate conductor boards 112, which are not connected to each other; a drain outlet 23 is also provided at the bottom of the casing 2. In this embodiment, a large perforated area 12 is provided on the rectifier circuit board 1 for drainage, and the drain outlet 23 is located below the perforated area 12. When water seeps into the stove body, the water will flow down through the large perforated area 12 to the bottom of the casing 2 and finally be discharged through the drain outlet 23, without accumulating water on the rectifier circuit board 1. Since the intermediate conductor boards 112 are not connected to each other, and the rectifier circuit board itself is covered with insulating varnish, the risk of short circuit caused by water accumulation on the rectifier circuit board 1 is avoided. This design can not only effectively prevent water from entering the rectifier circuit board 1, but also ensure the normal operation of the rectifier circuit board 1 and improve the service life of the electric flame stove.

[0030] In this embodiment, the rectifier circuit board 1, which is equipped with the connecting pin 14 and electrically connected to the intermediate lead plate 112, adopts a large-area hollow design, which affects the rigidity of the intermediate lead plate 112. The bottom of the housing 2 is provided with a mounting post 21 for fixing and connecting the rectifier circuit board 1 and a support pad 22 for supporting the intermediate lead plate 112. The support pad 22 prevents the intermediate lead plate 112 from deforming or breaking.

[0031] In this embodiment, the gap between the burner head 31 and the panel 3 is sealed with waterproof glue to prevent a large amount of external moisture from seeping into the stove body. A small amount of moisture seeping in from the arc generator 32 is discharged directly from the bottom drain port 23 through the hollow area 12.

[0032] In another embodiment, the non-perforated area 11 is provided with electronic components 13 and heat sinks for heat dissipation of electronic components 13. Electronic components 13 are sealed with waterproof adhesive. The side wall of the housing 2 is provided with heat dissipation grilles 24 for heat dissipation of the rectifier circuit board 1. A very small amount of water may drip onto electronic components 13. Since electronic components 13 are covered with waterproof adhesive, the water droplets will not damage electronic components 13 and will evaporate quickly.

[0033] like Figure 3-4 As shown, the present invention also proposes an electric flame stove, including the waterproof structure of the electric flame stove described in any of the above claims. The burner head 31 is provided with an arc generator 32, which is provided with an anode ion needle 321 and a cathode conductive cylinder 322. The cathode conductive cylinder 322 is conical in shape, and the intermediate guide plate 112 is provided with a connecting pin 14 for electrically connecting the anode ion needle 321 to the rectifier circuit board 1. The burner head 31 is also provided with a gas supply chamber 311 for supplying airflow to the arc generator 32, and the gas supply chamber 311 is provided with a gas supply fan 312 for increasing the airflow velocity. The arc generator 32 of the burner head 31 is a key component of the new electric flame stove. The arc generator 32 generates a high-temperature arc, forming a high-temperature plasma to heat the pot. When the electric flame stove is started, the gas supply fan 312 will start to rotate to generate airflow. The airflow enters the arc generator 32 through the gas supply chamber 311, and carries the high-temperature plasma out of the arc generator 32 through the cathode conductive cylinder 322. According to Bernoulli's theorem, "as the flow velocity increases, the static pressure of the fluid will decrease; conversely, as the flow velocity decreases, the static pressure of the fluid will increase." Since the cathode conductive cylinder 322 is a conical design with a relatively narrow air outlet at the top, the airflow velocity in the cathode conductive cylinder 322 gradually increases, thereby better heating the pot body above.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
