The air outlet 44 is communicated with the second vaporization chamber 422. The heating assembly 4 in the present application has small volume. In order to fully vaporize water, the heating body 42 is provided with a cuboid structure, and vaporization chambers are arranged on two surfaces respectively, so as to increase the vaporization path and make water fully vaporized. The heating body 42 in the present application is a new type of heating assembly, and the cuboid structure is better suitable for being installed in the cylindrical functional edge 1. The double-surface vaporization structure is more novel. The first vaporization chamber 421 and the second vaporization chamber 422 are provided with a heating body cover plate 427, which covers the two vaporization chambers respectively.

[0056] Referring to Figures 5 to 13In the above-mentioned embodiment of the present application, further comprising that at least two vaporization channels 425 are formed in the first vaporization chamber 421, one end of each of the vaporization channels 425 is communicated with the water inlet 41, the other end of each of the vaporization channels 425 is communicated with the air hole 423, and a baffle 426 is arranged in each of the vaporization channels 425.

One end of each of the vaporization channels 425 is communicated with the water inlet 41, and the other end of each of the vaporization channels 425 is communicated with the air hole 423. A water distribution plate 412 is arranged in the first vaporization chamber 421 close to the water inlet 41, the water inlet 41 is divided into two parts by the water distribution plate 412, and the water flows into two vaporization channels 425 respectively. The tapered protrusions 424 can block the water, so that the water can fully contact with the heating body 42, and the vaporization effect is improved. The baffle 426 can block the water, and the steam can climb over, so that the steam and water are separated.

[0057] Referring to Figures 5 to 13 In the above-mentioned embodiment of the present application, further comprising that a temperature sensing element mounting boss 45 is formed in the first vaporization chamber 421 close to the water inlet 41. The temperature sensing element mounting boss 45 exposes the heating body cover plate, and is used for fixing and mounting the temperature sensing element. The temperature sensing element is mounted here, and the temperature sensing is more sensitive.

[0058] Referring to Figures 5 to 13 In the above-mentioned embodiment of the present application, further comprising that a vaporization labyrinth is formed in the second vaporization chamber 422, one end of the vaporization labyrinth is connected with the air hole 423, and the other end of the vaporization labyrinth is connected with the air outlet 44. The vaporization labyrinth increases the passing distance of the steam, and the vaporization effect of the steam is better.

[0059] The heating assembly 4 in the present application can completely vaporize the entering water, the water amount entering the heating assembly 4 is controlled, and it is ensured that there is no water in the heating assembly 4. The heating assembly 4 can realize the rapid generation and rapid closing of the steam, so that the use and stop are realized.

[0060] Referring to Figures 4 to 18Further comprising in the above embodiment of the present application, the air outlet distribution disc 46 is integrally formed with the heat generating body 42, a plurality of air channels 461 are formed on the air outlet distribution disc 46, the air channels 461 are communicated with a center hole 462 of the air outlet distribution disc 46, and the center hole 462 is communicated with the air outlet 44. The air outlet distribution disc 46 is in a disc structure, and is integrally formed with the heat generating body 42, so that the air outlet distribution disc 46 also belongs to a part of the heat generating assembly, and has high temperature to continue heating the steam passing through to prevent condensate. The air channels 461 on the air outlet distribution disc 46 divide the steam into multiple portions, corresponding to each air outlet hole 11, to ensure that the high-temperature steam can be directly sprayed from the air outlet hole 11.

[0061] Referring to Figures 4 to 18 Further comprising in the above embodiment of the present application, a plurality of heat conducting sleeves 463 are formed on the air outlet distribution disc 46, a plurality of heat conducting columns 121 are formed on the ironing plate 12, and the heat conducting columns 121 are inserted into the heat conducting sleeves 463. The heat conducting columns 121 and the heat conducting sleeves 463 are connected together, so as to transmit the heat on the air outlet distribution disc 46 to the ironing plate 12, so that the ironing plate 12 has a certain temperature, and ironing can be realized.

[0062] Referring to Figures 4 to 18 Further comprising in the above embodiment of the present application, a heat insulation pad 464 is arranged between the air outlet distribution disc 46 and the ironing plate 12, and the air channel 461 is communicated with the air outlet hole 11. The above structure of the present application can realize the function of no dripping. When the steam brush is started to work, the temperature of the ironing plate 12 has not risen, and the temperature is low. When the steam contacts the ironing plate 12, condensate is generated, so that the steam brush drips at the initial stage of work. Since the steam brush is frequently started and stopped, the dripping problem will exist all the time, which seriously affects the use. The heat insulation pad 464 is arranged in the present application, so that the steam does not directly contact the ironing plate 12 with low temperature when the steam brush is started to work, and thus no dripping occurs. The heat insulation pad 464 prevents the steam from directly contacting the ironing plate 12 with low temperature to form condensate, so that the steam does not directly contact the ironing plate 12 with low temperature when the steam brush is started to work, and thus no dripping occurs. The air channel 461 is in a semi-closed structure, and the heat insulation pad 464 covers the air channel 461. Among the four surfaces of the air channel 461 formed by the cooperation of the heat insulation pad 464 and the air outlet distribution disc 46, three surfaces are high-temperature heat generating bodies, and one surface is the heat insulation pad 464 which is not easy to form condensate, so that the steam does not form condensate in the air channel. The steam is directly sprayed from the air outlet hole through the air channel of the air outlet distribution disc.

[0063] Referring to Figures 4 to 18In the above embodiment of the present application, the gas outlet nozzle 465 is connected to the end of the air channel 461 and directly communicates with the gas outlet hole 11 through the heat insulation pad 464. The steam is directly guided to the gas outlet hole 11 by the gas outlet nozzle 465, so that the steam does not contact the ironing plate 12, thereby further preventing condensation.

[0064] Referring to Figures 4 to 16 In the above embodiment of the present application, the heating tube 43 is coiled in the heating body 42, the middle part of the heating tube 43 is close to the water inlet 41, and the two wire ends 431 of the heating tube 43 are located at the front end of the heating body 42 and extend downward into the placing edge 2. In the present application, the heating assembly 4 is in an inverted manner, and the middle part of the heating tube 43 with the highest temperature is arranged at the water inlet 41, so that the water just entering can be directly vaporized. The two wire ends 431 of the heating tube 43 are led out from the front end of the heating assembly 4 and extend downward into the placing edge 2, thereby facilitating the placement and wiring of the wire ends. In the present application, the wire ends of the heating tube 43 are arranged at the connection between the functional edge 1 and the placing edge 2 and extend into the placing edge 2, thereby solving the problem of insufficient space of the functional edge 1. Since the wire ends are wired from the placing edge 2, the connection of the wire ends is more convenient.

[0065] Referring to Figures 4 to 16 In the above embodiment of the present application, part of the structure of the ironing plate 12 extends downward into the placing edge 2. The downward extension of the ironing plate 12 increases the area of the ironing end surface, thereby facilitating ironing. In addition, the position of the ironing plate 12 downward is flush with the wire ends of the heating tube 43, thereby protecting the wire ends.
