[0060] With the improvement of people's living standards, handheld steam devices, such as steam irons, steam hot pots, etc., are increasingly used in people's lives. Various handheld steam devices can quickly heat liquid water and vaporize it into high-temperature steam to meet people's different life needs such as ironing or cooking. In the related art, the handheld steam device is equipped with a steam generating component for generating steam. The steam generating component generally has a heating element and a steam chamber, and the heat generated by the heating element can be transferred to the steam chamber. When the user turns on the handheld steam device, liquid water enters the steam chamber through the water outlet point, and is then vaporized into high-temperature steam in the steam chamber by the heat generated by the heating element. Among them, most of the liquid water entering the steam chamber can be vaporized by the high temperature in the steam chamber at the water outlet point to generate steam. However, in the related art, the steam generating component has a technical problem of low vaporization efficiency.

[0061] In order to solve the above problems, the present application provides a steam generating assembly and an evaporation generating device, wherein a first evaporation chamber is arranged between a heating element and a cover plate, wherein the first evaporation chamber has a water drop point and a first diverter, and the first diverter is arranged at the water drop point to divert the liquid at the water drop point to the surrounding of the first evaporation chamber, so that the liquid can flow evenly to different positions of the first evaporation chamber, thereby improving the vaporization efficiency of the liquid in the first steam chamber into steam; in addition, a second evaporation chamber is arranged between the heating element and the bottom plate, the first evaporation chamber and the second evaporation chamber are connected through a first steam hole, and the vaporized steam and the residual liquid in the first evaporation chamber can enter the second evaporation chamber through the first steam hole for secondary evaporation, so that the liquid can be fully converted into steam and ejected through the second steam hole; wherein the first evaporation chamber and the second evaporation chamber are arranged in a stacked manner, so that the overall volume of the steam generating assembly can be reduced, and in addition, by arranging the second evaporation chamber, the heat of the heating element away from the first evaporation chamber can be fully utilized to avoid heat waste, effectively improve the heat utilization rate, and improve the water vaporization efficiency and conversion rate.

[0062] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0063] The embodiment of the present application provides a steam generating assembly, which can be applied to a garment steamer, an electric iron, a steam hot pot or other steam equipment to convert liquid into steam through the steam generating assembly. The following will take the application of the steam generating assembly to an iron as an example for introduction.

[0064] Figure 1 A schematic cross-sectional structure diagram of a steam generating assembly provided in an embodiment of the present application; Figure 2 A schematic top view of a steam generating assembly provided in an embodiment of the present application when a heating element is arranged on a bottom plate; Figure 3 A schematic top view of a bottom plate of a steam generating assembly provided in an embodiment of the present application; Figure 4 This is a bottom view schematic diagram of a heating element in a steam generating assembly provided in an embodiment of the present application.

[0065] Please refer to Figures 1 to 4 As shown, the steam generating assembly 100 provided in the embodiment of the present application includes a base plate 110, a heating element 120 and a cover plate 130, wherein the heating element 120 is located between the base plate 110 and the cover plate 130; illustratively, the base plate 110, the heating element 120 and the cover plate are stacked in sequence from bottom to top in the vertical direction; a first evaporation chamber 140 is formed between the heating element 120 and the cover plate 130, and a second evaporation chamber 150 is formed between the base plate 110 and the heating element 120; the heating element 120 has a first steam hole 121, and the first steam hole 121 is configured to connect the first evaporation chamber 140 and the second evaporation chamber 150, and the base plate 110 has a second steam hole 111 connected to the second evaporation chamber 150.

[0066] In some embodiments, the first evaporation chamber 140 has a water discharge point 131, and liquids such as water can enter the first evaporation chamber 140 through the water discharge point 131, wherein the liquid entering the first evaporation chamber 140 through the water discharge point 131 can be pure water, or it can be an aqueous solution with additives such as mixed spices, fungicides, essential oils, etc. The embodiments of the present application do not make specific limitations on this. hereinafter, the liquid entering the first evaporation chamber 140 through the water discharge point 131 is collectively referred to as water, and no specific description is given.

[0067] In addition, the heating element 120 can generate heat, and the first evaporation chamber 140 and the second evaporation chamber 150 are respectively arranged on opposite sides of the heating element 120. The heat generated by the heating element 120 on the side facing the cover plate 130 enters the first evaporation chamber 140, and the heat generated by the heating element 120 on the side facing the bottom plate 110 enters the second evaporation chamber 150; in this way, the water that encounters heat at the water outlet 131 will be converted into steam, and the water that is not converted into steam will enter the first evaporation chamber 140 through the water outlet 131, and gradually convert into steam in the first evaporation chamber 140. The steam in the first evaporation chamber 140 and the residual water (that is, the water that is not converted into steam in the first evaporation chamber 140) enter the second evaporation chamber 150 through the first steam hole 121, and are secondary vaporized in the second evaporation chamber 150 to improve the conversion rate and vaporization efficiency of water into steam, and can also avoid the waste of heat on the side of the heating element 120 away from the first evaporation chamber 140, thereby improving the utilization rate of heat; thereafter, the steam in the second steam chamber can be ejected through the second steam hole 111.

[0068] It can be understood that in the embodiment of the present application, by stacking the first evaporation chamber 140 and the second evaporation chamber 150 , the structural compactness of the steam generating assembly 100 is improved and the volume of the steam generating assembly 100 is reduced.

[0069] In some embodiments, the cover plate 130 has an openable and closable water inlet valve, which is connected to a water source through a water pipe. When the water inlet valve is opened, water can enter the first evaporation chamber 140 through the water outlet point 131, and the heat in the first evaporation chamber 140 vaporizes the water to form steam.

[0070] In some embodiments, the heating body 120 may include a heating element 123 and a heat-conducting shell 122 surrounding the outer periphery of the heating element 123 . The heating element 123 may generate heat by being energized, and the heat generated by the heating element 123 may be transferred to the first evaporation chamber 140 through the heat-conducting shell 122 .

[0071] In the embodiment of the present application, a heat-conducting housing 122 is provided on the outer circumference of the heat-generating element 123 to protect the heat-generating element 123 , thereby preventing the heat-generating element 123 from being easily touched and damaged.

[0072] Exemplarily, the heating element 123 includes but is not limited to an electric heating pipe, wherein the electric heating pipe can be located in the heat-conducting shell 122 in an S-shaped, U-shaped or spiral form to increase the laying area of ​​the electric heating pipe; the heat-conducting shell 122 is, for example, made of a heat-conducting material, and exemplary, the heat-conducting shell 122 includes but is not limited to a heat-conducting material such as aluminum.

[0073] In some embodiments, the heat conductive shell 122 and the heating element 123 are formed into an integral structure, for example, by a die-casting process. For example, the heat conductive shell 122 includes an upper shell and a lower shell, and the heating element 123 is located between the upper shell and the lower shell, and the upper shell and the lower shell are prepared by a die-casting process so that the heating element 123 and the heat conductive shell 122 form an integral structure. In this way, the waste of heat generated by the heating element 123 can be avoided, and all heat can be transferred to the first evaporation chamber 140 and the second evaporation chamber 150 through the heat conductive shell 122, thereby improving the heat efficiency, so that a smaller power heating element 123 can be used, which is energy-saving and environmentally friendly.

[0074] In order to further improve the evaporation efficiency of water in the first evaporation chamber 140, in some embodiments, please refer to Figure 2 As shown, a first diverter 160 is provided in the first evaporation chamber 140, and the first diverter 160 is provided at the water discharge point 131. For example, the water discharge point 131 is provided on the first diverter 160. In this way, the liquid at the water discharge point 131 can be diverted around the first evaporation chamber 140 through the first diverter 160 to increase the laying area and uniformity of the liquid in the first evaporation chamber 140, so as to improve the benefit rate of heat in the first evaporation chamber 140, and improve the vaporization efficiency of water and the conversion rate of water into steam.

[0075] Exemplarily, the first diverter 160 is a diverter baffle, a diverter protrusion or other structure, and is not limited here as long as it can divert the water at the water discharge point 131 to the surroundings.

[0076] It can be seen that in the embodiment of the present application, the first evaporation chamber 140 is arranged between the heating element 120 and the cover plate 130, and a first diverter 160 is arranged at a position corresponding to the water discharge point 131 in the first evaporation chamber 140. The water entering the first evaporation chamber 140 from the water discharge point 131 can be diverted by the first diverter 160, so that the water can flow evenly to different positions of the first evaporation chamber 140, thereby improving the vaporization efficiency of the liquid in the first steam chamber into steam. In addition, a second evaporation chamber 150 is arranged between the heating element 120 and the bottom plate 110, and the first evaporation chamber 140 and the second evaporation chamber 150 are connected by the first evaporation chamber 150. A steam hole 121 is connected, and the vaporized steam and residual liquid in the first evaporation chamber 140 can enter the second evaporation chamber 150 through the first steam hole 121 for secondary evaporation, so that the water can be fully converted into steam and sprayed out through the second steam hole 111; wherein, the first evaporation chamber 140 and the second evaporation chamber 150 are stacked, which can reduce the overall volume of the steam generating component 100. In addition, by setting the second evaporation chamber 150, the heat of the heating element 120 away from the first evaporation chamber 140 can be fully utilized to avoid heat waste, effectively improve the utilization rate of heat, and improve the vaporization efficiency and conversion rate of water.

[0077] In some embodiments, at least two diversion channels are arranged between the first diversion member 160 and the first steam hole 121, and the at least two diversion channels are evenly laid in the first evaporation chamber 140. The first diversion member 160 is configured to divert the liquid at the water outlet point to each diversion channel. In this way, the liquid at the water outlet point 131 is diverted to each diversion channel through the first diversion member 160, and the liquid is diverted to different positions in the first evaporation chamber 140 by at least two diversion channels to increase the contact area between the liquid and the first evaporation chamber 140, so that the liquid repeatedly absorbs the heat of the first evaporation chamber 140, thereby improving the utilization rate of the heat in the first evaporation chamber 140, avoiding heat waste, and improving the vaporization efficiency of the liquid.

[0078] In some embodiments, at least two diversion channels divert the liquid to different positions of the first evaporation chamber 140 to fully absorb the heat in the first evaporation chamber 140, and then merge to the first evaporation hole 121 for mixing, and then enter the second evaporation chamber 150 through the first evaporation hole 121 for secondary evaporation.

[0079] In some embodiments, Figure 2 As shown in the figure, at least two diversion channels include a first channel 141 and a second channel 142, and the first channel 141 and the second channel 142 are relatively arranged on opposite sides of the first diversion member 160, and the first channel 141 and the second channel 142 extend along the circumference of the first evaporation chamber 140 respectively, so that the water at the water drop point 131 is evenly diverted to the first channel 141 and the second channel 142 through the first diversion member 160, so that the water flows along the first channel 141 and the second channel 142 respectively, so as to increase the laying area and uniformity of the water in the first evaporation chamber 140, so that the water can fully absorb the heat of the first evaporation chamber 140, improve the heat benefit rate, and improve the vaporization efficiency and conversion rate of the water.

[0080] Exemplarily, a first isolation member and a second isolation member may be provided in the first evaporation chamber 140, so that a first flow channel 141 is formed by the first isolation member, and a second flow channel 142 is formed by the second isolation member, so that water at the water discharge point 131 is diverted into the first flow channel 141 and the second flow channel 142 through the first diverter 160. In this way, the problem of the steam generating component 100 being angularly deviated during use and affecting the flow direction of the water can be prevented.

[0081] The first isolating member and the second isolating member are, for example, isolating protrusions or isolating baffles, and any structure is acceptable as long as they can enclose and form the first flow channel 141 and the second flow channel 142 , and no limitation is made herein.

[0082] In some embodiments, at least two diversion channels also include a third channel 144 and a fourth channel 145, the third channel 144 is connected between the first channel 141 and the first steam hole 121, and the third channel 144 and the first channel 141 are located on one side of the first diverter 160, the fourth channel 145 is connected between the second channel 142 and the first steam hole 121, and the fourth channel 145 and the second channel 42 are located on the other side of the first diverter 160, so that the third channel 144 and the fourth channel 145 can further divert the liquid to increase the water laying area and uniformity, so as to further improve the utilization rate of heat in the first evaporation chamber 140 and avoid heat waste; thereafter, the liquid flowing in the third channel 144 and the fourth channel 145 is mixed at the first steam hole 121 and then enters the first steam hole 121 to balance the heat utilization rate of the third channel 144 and the fourth channel 145.

[0083] In some embodiments, at least one confluence structure is further provided between the water discharge point 131 and the first steam hole 121, and the confluence structure is configured to be connected to at least two branch flow channels so that the liquid flowing in at least two branch flow channels can be merged into the confluence structure. In this way, the liquid in each branch flow channel can enter the confluence structure for mixing to balance the difference in heat utilization in each branch flow channel, thereby improving the uniformity of the liquid temperature in the first evaporation chamber.

[0084] For example, Figure 2 As shown in the figure, the confluence structure includes a first confluence area 143, and the ends of the first flow channel 141 and the second flow channel 142 away from the first diverter 160 are both connected to the first confluence area 143, that is, the water in the first flow channel 141 and the second flow channel 142 enters the first confluence area 143 for mixing to balance the difference in heat utilization between the first flow channel 141 and the second flow channel 142, thereby improving the uniformity of the water temperature in the first evaporation chamber 140.

[0085] In some embodiments, the confluence structure also includes a second confluence area 146, which is configured to be connected between at least two branch flow channels and the first steam hole 121, so that the liquid in the at least two branch flow channels is mixed in the second confluence area 146 and then enters the first steam hole 121. In this way, the liquid in the at least two branch flow channels is mixed in the second confluence area 146 and then enters the second evaporation chamber 150 through the first steam hole for secondary evaporation, thereby improving the uniformity of the liquid temperature.

[0086] Exemplarily, the second confluence area 146 is configured to be connected to the third flow channel 144, the fourth flow channel 145 and the first steam hole 121, respectively. That is, the liquid in the third flow channel 144 and the fourth flow channel 145 are mixed in the second confluence area 146 to balance the difference in heat utilization between the third flow channel 144 and the fourth flow channel 145 and improve the uniformity of the water temperature; thereafter, the mixed liquid enters the first steam hole and enters the second evaporation chamber 150 for secondary evaporation.

[0087] In some embodiments, a dispersion structure is provided on at least one of the first diverter 160, at least two diverter channels and the confluence structure, and the dispersion structure is configured to disperse the liquid to the surroundings to increase the contact area between the liquid and the first evaporation chamber 140, improve the uniformity of water distribution in the first evaporation chamber 140, and thus improve the utilization rate of heat.

[0088] For example, please continue to refer to Figure 2 As shown, the diffusion structure includes a first diffusion structure 170, which is arranged on the first diverter 160 and opposite to the water discharge point 131. The first diffusion structure 170 is configured to disperse the liquid dripping from the water discharge point 131 in the circumferential direction of the water discharge point 131, so that the liquid entering the first evaporation chamber 140 can be further dispersed uniformly around the first flow channel 141 and the second flow channel 142, so as to improve the uniformity of water diversion to the first flow channel 141 and the second flow channel 142, thereby improving the utilization rate of heat in the first evaporation chamber 140, so that the liquid in the first evaporation chamber 140 can be quickly and fully converted into steam.

[0089] Exemplarily, the first diffusion structure 170 is a convex structure, for example, the first diffusion structure 170 is a convex structure such as a frustum or a prism, so as to slow down the flow speed of water and disperse the water to all sides.

[0090] The first diffuser structure 170 may be multiple, for example, Figure 2There are two first diffusion structures 170, and the two first diffusion structures 170 are relatively arranged on the first diverter 160 and located at the water discharge point 131, so as to disperse the water at the water discharge point 131 to the surroundings of the first flow channel 141 and the second flow channel 142 respectively, so as to improve the water laying area and uniformity. In some embodiments, the dispersion structure also includes a second dispersion structure 180. For example, the second dispersion structure 180 is provided in at least one of the first flow channel 141, the second flow channel 142 and the first confluence area 143, and the second dispersion structure 180 is configured to disperse the liquid passing through the second dispersion structure 180 to the surroundings; illustratively, any one, any two or all of the first flow channel 141, the second flow channel 142 and the first confluence area 143 are provided with a second dispersion structure 180 to reduce the flow velocity of water through the second dispersion structure 180 and distribute the water to the surroundings, so as to further disperse the liquid flowing in the first evaporation chamber 140, so as to improve the extensiveness and uniformity of the liquid laying in the first evaporation chamber 140, improve the utilization rate of heat in the first evaporation chamber 140, and improve the vaporization efficiency of the liquid.

[0091] There may be multiple second diffusion structures 180, and the multiple second diffusion structures 180 are arranged at intervals in the first evaporation chamber 140. As long as the water can be dispersed by the second diffusion structures 180 to increase the laying area and uniformity of the water in the first evaporation chamber 140, there is no limitation here.

[0092] For example, in Figure 2 In the embodiment, a plurality of second diffusion structures 180 are provided in the first confluence area 143, so as to slow down the flow velocity of water in the first confluence area 143 through the diffusion structures, so that the water entering the first confluence area 143 from the first flow channel 141 and the second flow channel 142 can be fully mixed; in addition, the water is further dispersed to the surroundings through the second diffusion structures 180, thereby increasing the laying area and uniformity of the water in the first confluence area 143, so as to make full use of the heat of different parts in the first evaporation chamber 140 and improve the utilization rate of the heat.

[0093] In some embodiments, the second diffusion structure 180 is, for example, a convex structure, for example, a convex structure such as a frustum or a prism, so as to slow down the flow speed of water and disperse the water to all sides.

[0094] It can be seen that in the embodiment of the present application, the water entering the first evaporation chamber 140 from the water drop point 131 is diverted, dispersed, merged, etc., so as to increase the laying area and uniformity of the water in the first evaporation chamber 140, thereby improving the utilization rate of the heat in the first evaporation chamber 140, improving the temperature uniformity of the water, and thus improving the vaporization efficiency and conversion rate of the water.

[0095] In some embodiments, Figure 2 As shown in the figure, a first guide structure 147 is provided between the first flow channel 141, the second flow channel 142 and the first confluence area 143, and the first guide structure 147 is configured to guide the water in the first flow channel 141 and the second flow channel 142 to the first confluence area 143, so that the liquid is guided by the first guide structure 147 when entering the first confluence area 143, so that the water in the first flow channel 141 and the second flow channel 142 enters the first confluence area 143 for mixing, so as to balance the difference in heat utilization between the first flow channel 141 and the second flow channel 142, thereby improving the uniformity of the water temperature.

[0096] Of course, a second guide structure 148 may also be provided between the second confluence area 146 and the first steam hole 121, and the second guide structure 148 is configured to guide the liquid in the second confluence area 146 to the first steam hole 121. In this way, the guidance of the second confluence area 146 when entering the first steam hole 121 is improved, so that the steam and residual water in the first steam chamber can enter the second evaporation chamber 150 for secondary evaporation, thereby improving the conversion rate of water into steam.

[0097] In some embodiments, please refer to Figure 3 As shown, the second evaporation chamber 150 has a second diverter 161, and the second diverter 161 is arranged at a position corresponding to the first evaporation hole. The second diverter 161 is configured to disperse the steam and water entering the second evaporation chamber 150 in the circumferential direction of the second evaporation chamber 150 to increase the laying area and uniformity of water and steam in the second evaporation chamber 150, so as to make full use of the heat in the second evaporation chamber 150 and avoid heat waste, thereby improving the vaporization efficiency.

[0098] Exemplarily, the diverter may be a diverter protrusion, a diverter baffle or other structures, as long as it can divert the water and steam entering the second evaporation chamber 150 through the first steam hole 121 to the surroundings of the second evaporation chamber 150 , and is not limited here.

[0099] In some embodiments, please refer to Figure 3 As shown, the second evaporation chamber 150 has at least two third diffusion structures 190, and the third diffusion structure 190 is configured to disperse the steam and water passing through the third diffusion structure 190 to the surroundings, so as to increase the laying area and uniformity of water and steam in the second evaporation chamber 150, so as to perform secondary evaporation in the second evaporation chamber 150 and improve the utilization rate of heat in the second evaporation chamber 150.

[0100] The third diffusion structure 190 may be a diffusion protrusion. For example, the third diffusion structure 190 may be a structure such as a frustum or a prism to disperse water and steam.

[0101] In addition, the steam generating assembly 100 also includes at least two heat transfer elements 112, and at least two heat transfer elements 112 are distributed at intervals along the circumference of the second evaporation chamber 150, and the two ends of each heat transfer element 112 are respectively connected to the heating element 120 and the bottom plate 110, and the heat transfer element 112 is configured to transfer the heat of the heating element 120 to the bottom plate 110. In this way, the heat of the heating element 120 can be transferred to the bottom plate 110 more quickly, thereby improving the heat transfer efficiency and heat utilization, and avoiding heat waste.

[0102] Exemplarily, at least two heat transfer elements 112 are evenly distributed in the circumferential direction of the second evaporation chamber 150 to transfer the heat of the heating element 120 to the bottom plate 110 , thereby improving the uniformity of the heat of the bottom plate 110 .

[0103] The heat transfer element 112 is, for example, a heat transfer column, a heat transfer protrusion, or other structures. The heat transfer element 112 may be made of a heat conductive material, and can quickly transfer the heat of the heating element 120 to the bottom plate 110 .

[0104] In some embodiments, the soleplate 110 is, for example, an ironing soleplate 110 used for ironing clothes in an iron, and the second steam hole 111 is disposed on the soleplate 110. The steam in the second steam chamber is ejected through the second steam hole 111 to increase the humidity of the ironed clothes, thereby improving the ironing effect.

[0105] In some embodiments, a heat transfer element 112 is arranged to form a heat transfer area, so that at least two heat transfer areas are evenly distributed along the circumference in the second evaporation chamber 150, and the heat transfer element 112 surrounds the second steam hole 111 in the heat transfer area, and each heat transfer element 112 has a notch 113, and the notch 113 is used to connect the heat transfer area and the outer peripheral area of ​​the heat transfer element 112, wherein each heat transfer area has a second steam hole 111, and illustratively, the number of the second steam holes 111 in each heat transfer area is equal, for example, in Figure 3 In the embodiment, each heat transfer area has three second steam holes 111 , thereby improving the uniformity of the steam ejected at different positions of the bottom plate 110 .

[0106] The volumes of the at least two heat transfer regions formed by the at least two heat transfer elements 112 are the same, that is, the volumes of the at least two heat transfer regions are uniform and evenly distributed along the circumference of the second evaporation chamber 150 .

[0107] It can be seen that in the embodiment of the present application, by arranging the heat transfer element 112 between the heating element 120 and the bottom plate 110, the heat transfer element 112 can quickly transfer the heat of the heating element 120 to the bottom plate 110, so as to provide heat to the bottom plate 110 for ironing clothes, thereby improving the utilization rate of heat; in addition, the steam and residual water entering the second evaporation chamber 150 are dispersed by the second diverter 161 and evenly dispersed into the second evaporation chamber 150, and then further dispersed by the third dispersion structure, and enter into each heat transfer area with uniform volume through the notch 113 on each heat transfer element 112, and then sprayed out through the second steam hole 111, thereby improving the uniformity of the amount of steam sprayed out of the second steam hole 111; and the small amount of residual water entering the heat transfer area will be evaporated again by the heat of the bottom plate 110, thereby maximizing the utilization of heat, reducing the probability of the second steam hole 111 spraying water outward, and improving the conversion rate of water into steam.

[0108] In some embodiments, please refer to Figure 4 As shown, the heating body 120 includes a heat-conducting shell 122 and a heating element 123 located in the heat-conducting shell 122. The heat-conducting shell 122 has a first area 124 and a second area 125 on the side facing the base plate 110. The contour of the first area 124 matches the contour shape of the heat-conducting element 112. The second area 125 is surrounded by the outer peripheral side of the first area 124. The second area 125 is a recessed area recessed toward the side of the cover plate 130.

[0109] That is to say, the first area 124 is arranged relative to the heat transfer element 112. For example, the projection of the first area 124 on the bottom plate 110 coincides with the projection of the outline of the heat transfer element 112 on the bottom plate 110, so that the heat transfer element 112 is connected between the first area 124 and the bottom plate 110, and the second area 125 is surrounded by the outer side of the first area 124, and part of the material of the second area 125 is removed so that the second area 125 forms a recessed area extending away from the bottom plate 110 relative to the first area 124, that is, the material of the second area 125 is reduced. In this way, the overall weight of the steam generating assembly 100 can be reduced, material costs can be saved, and the purpose of lightweighting the steam generating assembly 100 can be achieved, thereby improving the user experience when using it.

[0110] In the embodiment of the present application, the first area 124 of the heat-conducting shell 122 is reduced in material, and the wall thickness around the heating element 123 is made uniform, while the weight of the steam generating assembly 100 is reduced, so that the steam generating assembly 100 is lightweight in design, thereby improving the user experience.

[0114] The steam generating assembly and the steam generating device provided by the embodiment of the present application are provided with a first evaporation chamber between the heating element and the cover plate, wherein the first evaporation chamber has a water drop point and a first diverter, and the first diverter is provided at the water drop point to divert the liquid at the water drop point to the periphery of the first evaporation chamber, so that the liquid can flow evenly to different positions of the first evaporation chamber, thereby improving the vaporization efficiency of the liquid in the first steam chamber into steam; in addition, a second evaporation chamber is provided between the heating element and the bottom plate, the first evaporation chamber and the second evaporation chamber are connected through a first steam hole, and the vaporized steam and the residual liquid in the first evaporation chamber can enter the second evaporation chamber through the first steam hole for secondary evaporation, so that the liquid can be fully converted into steam and ejected through the second steam hole; wherein the first evaporation chamber and the second evaporation chamber are stacked, so that the overall volume of the steam generating assembly can be reduced, and in addition, by providing the second evaporation chamber, the heat of the heating element away from the first evaporation chamber can be fully utilized to avoid heat waste, effectively improve the heat utilization rate, and improve the water vaporization efficiency and conversion rate.
