[0039] like Figures 1 to 3 As shown, this application provides an electric iron 10, which includes a housing 100 and a ceramic heating plate 200. The housing 100 has a water tank 110 for storing water. The ceramic heating plate 200 is disposed on the bottom side of the housing 100, and a steam groove 230 is disposed on the top side of the ceramic heating plate 200. The steam groove 230 is connected to the water tank 110, and a steam hole 240 connected to the steam groove 230 is also disposed on the bottom side of the ceramic heating plate 200.

[0040] The electric iron 10 provided in this application effectively improves the heating and ironing efficiency by utilizing the high heating speed and high operating temperature of the ceramic heating plate 200. In addition, by providing a steam groove 230 and a steam hole 240 on the top and bottom sides of the ceramic heating plate 200 respectively, when the ceramic heating plate 200 heats up and conducts heat to the steam groove 230, the water flowing into the steam groove 230 will be heated into steam and discharged through the steam hole 240. At this time, the bottom side of the ceramic heating plate 200 can be placed against the part of the garment to be ironed, and the steam and the temperature of the ceramic heating plate 200 can be used to iron the part of the garment to be ironed. Therefore, the electric iron 10 of this application effectively improves the heating and ironing performance by combining the function of steam immersion to soften the garment.

[0041] like Figure 4 As shown, in one embodiment, the ceramic heating plate 200 includes a ceramic base 210 and a heating film 220. The heating film 220 is disposed on the inner side of the ceramic base 210. A steam groove 230 is disposed on the top side of the ceramic base 210, and a steam hole 240 is disposed on the bottom side of the ceramic base 210.

[0042] Specifically, when the electric iron 10 is turned on, the heating film 220 is energized and heated, and the heat is conducted to the ceramic base 210 and the steam groove 230 located on the top side of the ceramic base 210. During this process, when the water in the water tank 110 flows into the steam groove 230, the water in the steam groove 230 is heated into steam and discharged through the steam hole 240. At this time, the bottom side of the ceramic base 210 can be placed against the part of the garment to be ironed, and the steam and the temperature of the heating film 220 can be used to iron the part of the garment to be ironed. Therefore, through the integrated structural design of the ceramic base 210 and the heating film 220, the assembly structure of the traditional heating element and base can be simplified, and heat loss can be reduced, thereby improving heating efficiency and temperature control accuracy. Furthermore, by utilizing the high heating speed and high operating temperature of the heating film 220, combined with the function of steam immersion to soften the clothes, the electric iron 10 effectively improves the heating and ironing efficiency and performance of the electric iron 10.

[0043] In this process, a semiconductor heating material can be coated (using processes such as spraying or deposition) onto the inner side of the ceramic chassis 210 to form a heating film 220. The ceramic chassis 210 can be made of ceramic materials such as silicon nitride, aluminum nitride, and zirconium oxide, or processed from materials such as quartz and microcrystalline glass. When using a ceramic chassis 210 as the chassis structure, the high hardness of ceramic materials and the smooth surface of the ceramic chassis 210 eliminate the need for additional coatings, simplifying its structure. Furthermore, the ceramic chassis 210 exhibits good oxidation resistance and durability, resulting in a long service life.

[0044] In one embodiment, the heating film 220 may be a nano-rare earth oxide heating film sprayed on the inner side of the ceramic chassis 210.

[0045] Furthermore, when using the heating film 220 as the heating element, the heating film 220 can cover the inner surface of the ceramic base 210 as much as possible, resulting in a larger heat conduction area between the heating film 220 and the ceramic base 210. When the heating film 220 heats up, it can evenly conduct heat to the ceramic base 210, allowing the ceramic base 210 to heat up uniformly and improving the ironing effect. Moreover, the heating film 220 can be directly bonded to the ceramic base 210, reducing the need for a fixed structure for the heating element and thus simplifying the structure of the electric iron 10.

[0046] like Figure 2 As shown, in one embodiment, a heating area 250 corresponding to the position of the heating film 220 is provided on the top side of the ceramic chassis 210, and the heating area 250 defines the boundary of the projection of the heating film 220 on the top side of the ceramic chassis 210.

[0047] In an optional embodiment, the ceramic heating plate 200 includes a ceramic base 210 and a silicon carbide heating structure. The silicon carbide heating structure is disposed inside the ceramic base 210. A steam groove 230 is provided on the top side of the ceramic base 210, and a steam hole 240 is provided on the bottom side of the ceramic base 210. Optionally, the ceramic base 210 and the silicon carbide heating structure are integrally formed. Optionally, the silicon carbide heating structure is provided with multiple through holes, the shape of which can be any one of circular, square, prismatic, and hexagonal, to facilitate better heat dissipation of the silicon carbide heating structure.

[0048] like Figure 2 and Figure 3 As shown, specifically, the steam tank 230 can be a U-shaped tank, and the steam tank 230 is arranged around the heating zone 250 so that the heating film 220 can heat the water flowing into the steam tank 230 into steam more quickly. Furthermore, there are multiple steam holes 240, which are evenly distributed along the extension direction of the steam tank 230. The evenly distributed steam holes 240 allow the steam to contact the part of the clothing to be ironed more evenly.

[0049] like Figure 2 As shown, the front end of the ceramic base 210 is further curved on both sides as arc surfaces 211. The front end of the ceramic base 210 forms a pointed part 212 by the intersection of the curved arc surfaces 211 on both sides. By setting this pointed part 212, it is easier to iron the hard-to-reach areas of clothes.

[0050] like Figure 5As shown, the water tank 110 includes a water tank body 111, a top cover 112, and a bottom cover 113. The top cover 112 is disposed at the top opening of the water tank body 111, and the bottom cover 113 is disposed at the bottom opening of the water tank body 111. Further, the housing 100 also includes a bottom shell 114, which is disposed at the bottom of the water tank 110. Specifically, the bottom shell 114 is disposed at the bottom of the bottom cover 113 of the water tank 110, and the ceramic heating plate 200 is disposed at the bottom of the bottom shell 114.

[0051] Furthermore, the housing 100 also includes a handle portion 115 for easy operation of the electric iron 10 by the user. The handle portion 115 is disposed on the top side of the water tank 110. Specifically, the handle portion 115 is disposed at the connection between the water tank body 111 and the top cover 112.

[0052] like Figure 5 As shown, the water tank 110 is further provided with an inlet 116 communicating with the water tank 110 on its top side, and an outlet communicating with the steam tank 230 on its bottom side. The inlet 116 is used to supply water into the water tank 110, and the water in the water tank 110 can flow into the steam tank 230 through the outlet. Specifically, the inlet 116 is provided on the handle part 115 (specifically, it can be provided on the front end of the handle part 115), and the outlet is provided on the bottom cover 113 of the water tank 110.

[0053] Furthermore, a cover plate 117 is provided at the water inlet 116. The cover plate 117 is used to open or close the water inlet 116. In this way, when it is not necessary to add water to the water tank 110, the water inlet 116 can be closed through the cover plate 117 to prevent external debris from falling into the water tank 110 through the water inlet 116.

[0054] Furthermore, a first water outlet 118 is provided on the bottom shell 114. The first water outlet 118 connects the water tank 110 and the steam tank 230, and the water output from the water tank 110 can flow into the steam tank 230 through the first water outlet 118. Specifically, the position of the first water outlet 118 corresponds to the position of the water outlet of the water tank 110, and the water in the water tank 110 can flow into the steam tank 230 in sequence through the water outlet and the first water outlet 118.

[0055] like Figure 5As shown, the electric iron 10 further includes a first sealing cover 300, which covers the ceramic heating plate 200 to ensure that water can only flow within the ceramic heating plate 200, preventing water from overflowing into the electric iron 10. Specifically, the first sealing cover 300 covers the steam tank 230 and the heating zone 250. Furthermore, the electric iron 10 also includes a second sealing cover 400, which covers the heating zone 250, giving the heating zone 250 a sealing and steam-proof function, preventing steam from entering the heating zone 250. Specifically, the second sealing cover 400 is covered by the first sealing cover 300. The first sealing cover 300 is provided with a second water outlet 310 corresponding to the first water outlet 118. The second water outlet 310 is connected to the steam tank 230, and the water in the water tank 110 can flow into the steam tank 230 in sequence through the water outlet, the first water outlet 118, and the second water outlet 310.

[0056] Furthermore, the electric iron 10 also includes a control board, which can be a PCB board, and the control board is electrically connected to the heating film 220.

[0057] like Figure 2 As shown, the heating film 220 is electrically connected to a terminal 260, which is exposed to the outside through the top side of the ceramic base 210. The terminal 260 is electrically connected to the control board. Specifically, the tail end of the heating film 220 is provided with two terminals 260, namely a positive terminal 262 and a negative terminal 264. Both the positive terminal 262 and the negative terminal 264 are exposed to the outside through the top side of the ceramic base 210, and both the positive terminal 262 and the negative terminal 264 are used to be electrically connected to the control board through a connecting wire.

[0058] like Figure 1 and Figure 5 As shown, the housing 100 is further provided with operation control keys 500 for adjusting the electric iron 10. The operation control keys 500 include at least one of a power switch key, a speed adjustment key, and a temperature adjustment key. Specifically, the operation control keys 500 are electrically connected to the control board. A first operation control key 510 is provided on the handle portion 115. The first operation control key 510 can be a control button and is located near the water inlet 116. A second operation control key 520 is provided on the water tank 110. The second operation control key 520 can be a control knob and is located on the side of the water tank body 111 near the handle portion 115.

[0059] Furthermore, the electric iron 10 also includes a power cord 600 for connecting to electricity. The power cord 600 is disposed on the housing 100. Specifically, the power cord 600 is disposed on the handle portion 115 (specifically, it can be disposed at the rear end of the handle portion 115). The power cord 600 is electrically connected to the control board.
