It is to be understood that data so designated are interchangeable such that the embodiments of the present application described herein could operate in other sequences, or be combined in other ways, than illustrated or described herein.

[0064] Furthermore, the terms "comprise", "comprising", "have", "having", "include", "including", "contain", "containing", "provide", "providing", and the like, are used in the detailed description and in the claims of this application and are open-ended, allowing for instances where additional steps or elements are added, unless otherwise noted.

[0065] An iron is a household appliance used to remove wrinkles on clothes and make clothes smooth. The iron usually has an ironing surface, and a user can hold the iron to make the ironing surface contact clothes to be ironed for ironing.

[0066] In the related art, the iron further includes a boiler, a water tank, and a water pump, the boiler is connected with the water tank through the water pump, an ironing surface cover is arranged on the boiler, and the ironing surface has a steam hole in communication with the boiler. The water pump pumps water in the water tank into the boiler, a heating element in the boiler can heat the water to the boiling point, and steam is sprayed to clothes to be ironed through the ironing surface.

[0067] However, in some application scenarios, for example, when steam formed by heating water through the heating element is directly led out through the steam hole on the ironing surface, the steam path is short, which causes the steam to be unable to uniformly take away the heat of the heating element. As a result, on the one hand, the steam amount is small, and the steam vaporization effect is poor, which is prone to form condensate at the ironing surface. On the other hand, the steam heat absorption is uneven, which causes local high temperature of the boiler and the ironing surface, and cannot guarantee the uniformity of the temperature of the boiler and the ironing surface, thereby affecting the ironing effect.

[0068] Therefore, embodiments of the present application provide a steam boiler, an ironing head, and an ironing device. The steam boiler is used for the ironing head, and includes a heating shell and a heating element. A water inlet is arranged on the heating shell, water can be injected into the heating shell through the water inlet. A first accommodating cavity and a second accommodating cavity are arranged in the heating shell in a separated manner. The first accommodating cavity has at least one first steam passage, and the second accommodating cavity has at least one second steam passage. The first steam passage and the second steam passage are connected in sequence and alternately to form a steam flow channel. One end of the steam flow channel is in communication with the water inlet to receive the injected water. The heating element is arranged in the heating shell, the first steam passage and the second steam passage are arranged around the heating element, and the other end of the steam flow channel is in communication with an ironing opening of the ironing head in use.

[0069] Thus, by heating the steam flow channel, the design of the steam flow channel can prolong the flow path of the steam and make the steam flow through the entire surface area of the heating element to absorb heat more evenly during the process of vaporizing water into steam by injecting water into the steam flow channel through the water injection port, which is conducive to improving the steam amount and the uniformity of the overall temperature of the steam boiler and reducing the local high temperature phenomenon.

[0070] Hereinafter, the present application will be described in detail in conjunction with the drawings and specific embodiments.

[0071] Referring to Figures 1 to 5 The steam boiler 100 provided by the embodiments of the present application is used for the ironing head 200, and the steam boiler 100 includes a heating shell 110 and a heating element 120. The heating shell 110 is provided with a water injection port 1121, and the heating shell 110 is divided into a first containing cavity 101 and a second containing cavity 102. The first containing cavity 101 has at least one first steam passage 1011, and the second containing cavity 102 has at least one second steam passage 1021. The first steam passage 1011 and the second steam passage 1021 are connected in sequence and alternately to form a steam flow channel. One end of the steam flow channel is communicated with the water injection port 1121, and the other end of the steam flow channel is used to communicate with an ironing port 2111 of the ironing head 200.

[0072] The heating element 120 is located in the heating shell 110, and the first steam passage 1011 and the second steam passage 1021 are both arranged around the heating element 120. The heating element 120 is configured to heat the steam flow channel to vaporize water injected into the steam flow channel through the water injection port 1121 into steam and spray out through the ironing port 2111.

[0073] Specifically, the heating shell 110 serves as the shell of the steam boiler 100 and is used to provide the space required for steam generation and flow. Through the first containing cavity 101 and the second containing cavity 102, the channels for steam flow are arranged to prolong the steam flow path.

[0074] The heating element is used to heat water to the boiling point, thereby generating steam.

[0075] The ironing port 2111 of the ironing head 200 serves as the outlet of the steam and is used to aim at the clothes to be ironed and spray the generated steam onto the clothes to be ironed.

[0076] The specific number of the first steam passage 1011 and the second steam passage 1021 is not limited in the embodiments of the present application. For example, the number of the first steam passage 1011 and the second steam passage 1021 can be one. One end of the first steam passage 1011 is communicated with the water injection port 1121, and the other end is communicated with one end of the second steam passage 1021. The other end of the second steam passage 1021 is used to communicate with the ironing port 2111 of the ironing head 200 to form a steam flow channel. In this way, the path of steam flow is optimized, and the phenomenon that steam cannot uniformly take away the heat of the heating element 120 due to a short steam path is reduced.

[0077] For another example, the number of the first steam passage 1011 and the second steam passage 1021 can be two. One end of one of the two first steam passages 1011 is communicated with the water injection port 1121, and the other end of the one of the two first steam passages 1011 is communicated with one end of one of the two second steam passages 1021. The other end of the one of the two second steam passages 1021 is further communicated with one end of the other of the two first steam passages 1011. The other end of the other of the two first steam passages 1011 is further communicated with one end of the other of the two second steam passages 1021. The other end of the other of the two second steam passages 1021 is used to communicate with the ironing port 2111 of the ironing head 200. In this way, the steam flow channel is formed by the first steam passage 1011 and the second steam passage 1021 being communicated in turn and alternately, and the path of steam flow can be further prolonged.

[0078] The one end of the one of the two first steam passages 1011 is one end of the steam flow channel, and the other end of the other of the two second steam passages 1021 is the other end of the steam flow channel.

[0079] It can be understood that the heating element 120 in the embodiments of the present application is located in the heating shell 110, and the first steam passage 1011 in the first accommodating cavity 101 and the second steam passage 1021 in the second accommodating cavity 102 are both arranged around the heating element 120, so that the steam flow channel formed by the first steam passage 1011 and the second steam passage 1021 being communicated in turn and alternately is in a state of being wound between the first accommodating cavity 101 and the second accommodating cavity 102.

[0080] In specific implementation, the heating element is arranged between the first accommodating cavity 101 and the second accommodating cavity 102, and the first steam passage 1011 and the second steam passage 1021 are both arranged around the heating element 120. In this way, after water is injected through the water injection port 1121, the water can fully and uniformly contact the heating element 120 in the process of flowing in the steam flow channel, which is beneficial to ensuring effective heat transfer and making the water uniformly absorb the heat of the heating element 120 to promote rapid vaporization of the water.

[0081] It should be noted that the number of the first steam passage 1011 and the second steam passage 1021 can also be set to more than two, and the specific process of forming the steam flow channel by the first steam passage 1011 and the second steam passage 1021 can refer to the above process, and the embodiments of the present application will not be described again.

[0082] In summary, the steam boiler 100 provided by the embodiments of the present application heats the steam flow channel formed by the first steam passage 1011 and the second steam passage 1021 connected in turn and alternately by the heating member. In the process of heating the water injected into the steam flow channel through the water injection port 1121 into steam by the heating member, since the first steam passage 1011 and the second steam passage 1021 are both arranged around the heating member 120, the design of the steam flow channel can prolong the flow path of the steam and make the steam flow through the entire surface area of the heating member 120 to more evenly absorb heat, which is beneficial to improve the steam quantity and the uniformity of the overall temperature of the steam boiler 100 and reduce the local high temperature phenomenon.

[0083] Referring to Figure 2 and Figure 3 In some embodiments, the heating shell 110 includes a heating seat 111 and a cover plate 112; the cover plate 112 is covered on the heating seat 111, and the cover plate 112 and the heating seat 111 together define a first containing cavity 101, and the water injection port 1121 is located on the cover plate 112; the side of the heating seat 111 away from the cover plate 112 defines a second containing cavity 102, and the second containing cavity 102 is used to cover the ironing port 2111.

[0084] In this way, by the combined design of the heating seat 111 and the cover plate 112, the space required for steam generation and flow is constructed, which is convenient for subsequent setting of the first steam passage 1011 and the second steam passage 1021 therein, and is beneficial to make the steam boiler 100 more compact, convenient for user operation and storage; when specifically implemented, the water injection port 1121 is arranged on the cover plate 112, which can make it away from the heating area, and can reduce the risk of water leakage at the water injection port 1121 due to high temperature.

[0085] The specific structure of the heating seat 111 is not limited by the embodiments of the present application, and exemplarily, the heating seat 111 can include, for example, Figure 2The cover body part 1114 and the mounting part 1115 located in the cover body part 1114 are shown, wherein the cover body part 1114 includes two straight line segments 1116 and two curved transition segments 1117, the straight line segments 1116 and the curved transition segments 1117 are alternately connected in sequence to form a symmetrical structure, which is beneficial to improve the overall appearance of the boiler; the side of the mounting part 1115 facing the ironing port 2111 and part of the circumferential side of the cover body part 1114 jointly define a second containing cavity 102, and the side of the mounting part 1115 facing away from the ironing port 2111, the remaining part of the cover body part 1114 and the cover plate 112 jointly enclose a first containing cavity 101.

[0086] It should be noted that the heating element 120 can be embedded into the mounting part 1115, and the heating element 120, the cover body part 1114 and the mounting part 1115 are integrally formed; the cover plate 112 can be connected with the heating seat 111 by screws 113.

[0088] In this way, the water injected through the water injection port 1121 can flow smoothly from one end of the first flow guide part 1012 to the second flow guide part under the guidance of the first flow guide part 1012; since the first flow guide part 1012 is arranged around the circumferential side of the heating seat 111 and the first communication hole 1111 is adjacent to the water injection port 1121, the water can flow around the heating element 120 during the water flow to contact the side of the heating element 120 sufficiently, which is beneficial to make the water fully utilize the heat of the heating element 120 to vaporize into steam, thereby improving the vaporization efficiency.

[0089] In specific implementation, by arranging the first communication hole 1111 on the heating seat 111 and making the other end of the first flow guide part 1012 communicate with the first communication hole 1111, the first flow guide part 1012 defines a first steam passage 1011, and the water injected through the water injection port 1121 can flow in the first steam passage 1011 and then enter the second steam passage 1021 of the second containing cavity 102 from the first communication hole 1111.

[0090] Referring to Figure 6 As shown, the arrows in the figure show the flow path of the water injected through the water injection port 1121 in the first steam passage 1011 of the first containing cavity 101 flowing to the first communication hole 1111.

[0091] Further, referring to Figures 4 to 7 , the at least one second steam passage 1021 comprises a second flow guide 1022, the second flow guide 1022 is located on a side of the heating seat 111 away from the cover plate 112, the second flow guide 1022 is arranged around the periphery of the heating seat 111, the heating seat 111 is provided with a second communication hole 1112, the first communication hole 1111 communicates with the second communication hole 1112 through the second flow guide 1022, and the second communication hole 1112 is adjacent to the first communication hole 1111.

[0092] In this way, the steam flowing into the second steam passage 1021 through the first communication hole 1111 can flow smoothly under the guidance of the second flow guide 1022; by arranging the second flow guide 1022 around the periphery of the heating seat 111, the steam can be ensured to flow around the heating element 120 to contact the other side of the heating element 120 sufficiently during the steam flow, thereby combining the first flow guide 1012 to make the steam can uniformly absorb the heat of the heating element 120, so that the water is more fully vaporized and the phenomenon of local high temperature of the steam boiler 100 as a whole is reduced.

[0093] In specific implementation, a second steam passage 1021 is defined by the second flow guide 1022, the second communication hole 1112 is arranged on the heating seat 111, and the first communication hole 1111 communicates with the second communication hole 1112 through the second flow guide 1022, in this way, after flowing into the second steam passage 1021 through the first communication hole 1111, the steam can enter the first containing cavity 101 from the second communication hole 1112 to continue flowing in another first steam passage 1011, thereby the steam flow path can be further prolonged to more fully and uniformly absorb the heat of the heating element 120.

[0094] As shown in Figure 7 , the arrows in the figure show the flow path of the steam flowing into the second communication hole 1112 in the second steam passage 1021 in the second containing cavity 102 through the first communication hole 1111.

[0095] It can be understood that in specific implementation, by arranging the second communication hole 1112 adjacent to the first communication hole 1111, the steam flow path in the second steam passage 1021 defined by the second flow guide 1022 can be prolonged, and the second steam passage 1021 can be more reasonably arranged in the second containing cavity 102.

[0096] In some examples, referring to Figures 4 to 8At least one first steam passage 1011 includes a third guide portion 1013, the third guide portion 1013 is located on the side of the heating base 111 facing the cover plate 112, the third guide portion 1013 is located in the area enclosed by the first guide portion 1012, the heating base 111 is provided with a third connecting hole 1113, a second connecting hole 1112 connects the third guide portion 1013 and the third connecting hole 1113, and the third connecting hole 1113 is adjacent to the second connecting hole 1112.

[0097] Thus, by forming another first steam channel 1011 in the first receiving cavity 101 through the third guide section 1013, the flow path of steam in the first receiving cavity 101 is increased; by placing the third guide section 1013 in the area enclosed by the first guide section 1012, the heating element 120 is more fully covered, so that the steam uniformly carries away the heat on one side of the heating element 120, reducing the phenomenon of local high temperature on one side of the heating element 120.

[0098] Among them, reference Figure 8 As shown in the figure, the arrows indicate the flow path of steam flowing in through the second connecting hole 1112 to the third connecting hole 1113 in another first steam channel 1011.

[0099] Understandably, in a specific implementation, by setting the third connecting hole 1113 adjacent to the second connecting hole 1112, the flow path of steam within the first steam channel 1011 defined by the third guide part 1013 can be extended, thereby achieving a more reasonable arrangement of the first steam channel 1011 within the first receiving cavity 101.

[0100] Furthermore, referring to Figures 4 to 9 At least one second steam passage 1021 includes a fourth guide portion 1023, which is located on the side of the heating base 111 away from the cover plate 112. The fourth guide portion 1023 is located in the area enclosed by the second guide portion 1022. The fourth guide portion 1023 is bent from the periphery of the heating base 111 and extends to the middle of the heating base 111. The third connecting hole 1113 and the ironing opening 2111 are connected through the fourth guide portion 1023.

[0101] Thus, by forming another second steam channel 1021 in the second receiving cavity 102 through the fourth guide section 1023, the flow path of steam in the second receiving cavity 102 is increased; by placing the fourth guide section 1023 in the area enclosed by the second guide section 1022, the heating element 120 is more fully covered, and the steam evenly carries away the heat on the other side of the heating element 120, which is beneficial to increasing the amount of steam; by connecting the third connecting hole 1113 and the ironing nozzle 2111 through the fourth guide section 1023, the steam can be ensured to be smoothly ejected from the ironing nozzle 2111 after overlapping flow on both sides of the heating element 120.

[0102] Among them, reference Figure 9 As shown in the figure, the arrows indicate the flow path of steam flowing in through the third connecting hole 1113 to the ironing opening 2111 in another second steam channel 1021.

[0103] Reference Figure 4 and Figure 5 In a specific implementation, at least one of the first guide section 1012, the second guide section 1022, the third guide section 1013, and the fourth guide section 1023 is a tortuous guide channel; or, at least one of the first guide section 1012, the second guide section 1022, the third guide section 1013, and the fourth guide section 1023 is surrounded by a guide plate 130 to form a tortuous flow channel.

[0104] Thus, water and steam can be guided to flow stably through the channel wall or guide plate 130; the tortuous design or tortuous flow channel of the guide channel can optimize the length of the flow path in the limited space of the heating shell 110, which is conducive to miniaturization and portable design while ensuring that the steam carries away the heat of the heating element 120 evenly.

[0105] Reference Figure 2 In some embodiments, the steam boiler 100 also includes a water inlet connector 140, which is disposed on the water inlet 1121.

[0106] In this way, the water inlet connector 140 can be connected to an external water source, such as a water pipe or a water storage container, making it easier for users to add water to the steam boiler 100 without having to laboriously pour water into the water inlet 1121, which helps to improve user convenience and water injection efficiency.

[0107] Furthermore, the steam boiler 100 also includes a seal 150 disposed between the water inlet 1121 and the water inlet connector 140 to seal the gap between the water inlet 1121 and the water inlet connector 140.

[0108] This reduces water leakage during the injection process and minimizes the entry of dust and other impurities into the steam boiler 100 through the gap between the water inlet 1121 and the water inlet connector 140, keeping the inside of the steam boiler 100 clean and simplifying daily cleaning and maintenance.

[0109] In a specific implementation, the seal 150 can be set as a sealing ring, wherein the sealing ring is made of elastic material and achieves sealing through compression.

[0110] Reference Figure 10 and Figure 11The ironing head 200 provided by the embodiment of the present application comprises an ironing head body 210 and the steam boiler 100 in any of the foregoing embodiments; the other end of the steam flow channel of the steam boiler 100 is in communication with the ironing port 2111 of the ironing head body 210.

[0111] The overall structure and working principle of the steam boiler 100 are the same as those in the foregoing embodiments, and will not be described herein again.

[0112] The ironing head 200 provided by the embodiment of the present application comprises an ironing head body 210 and the steam boiler 100 in any of the foregoing embodiments; the other end of the steam flow channel of the steam boiler 100 is in communication with the ironing port 2111 of the ironing head body 210.

[0113] Specifically, the ironing head body 210 comprises an ironing panel 211 and a protective cover 212; the ironing port 2111 is located on the ironing panel 211, the protective cover 212 is arranged on the ironing panel 211, and the protective cover 212 and the ironing panel 211 jointly enclose a mounting cavity 201, and the heating shell 110 of the steam boiler 100 is located in the mounting cavity 201.

[0114] In this way, when the ironing head 200 is used, the ironing panel 211 is brought into contact with clothes, so that the steam sprayed through the ironing port 2111 can act on the clothes; meanwhile, the protective cover 212 separates the high-temperature area of the steam boiler 100 during operation, thereby reducing the risk of burns caused by accidental touching of the user.

[0115] Reference Figure 12 In some examples, at least one of the second flow guide part 1022 and the fourth flow guide part 1023 of the steam boiler 100 encloses a zigzag flow channel by the flow guide plate 130; the ironing panel 211 has a support part 2113 matched with the flow guide plate 130, and the flow guide plate 130 is partially inserted into the support part 2113.

[0116] Thus, the support part 2113 can form a flow path on the ironing panel 211 that matches the second steam channel 1021, so that heat can be transferred evenly, ensuring the overall temperature consistency of the ironing panel 211 and improving the ironing effect; at the same time, the support part 2113 provides a fixing point for the guide plate 130, so that the steam boiler 100 and the ironing panel 211 can maintain a stable relative position, reducing displacement caused by vibration or external force.

[0117] Among them, reference Figure 12 As shown in the figure, the arrows indicate the flow path of steam flowing in through the third connecting hole 1113 on the ironing panel 211 towards the ironing opening 2111.

[0118] Reference Figure 10 and Figure 11 In some embodiments, the ironing panel 211 is provided with an air intake 2112, which is connected to the mounting cavity 201.

[0119] Thus, a suction component 220 can be configured in the mounting cavity 201, so that the air inlet 2112 is connected to the air inlet of the suction component 220 through the receiving cavity. During the ironing process, the suction component 220 generates negative pressure and draws air through the air inlet 2112, so that the clothes to be ironed are adsorbed on the ironing panel 211, which can ensure the ironing effect.

[0120] In practice, there are multiple air intakes 2112, which are arranged at intervals around the periphery of the heating housing 110.

[0121] This ensures that air enters the air intake 2112 evenly and smoothly, which helps to form a more stable airflow around the entire air intake 2112, avoiding local airflow disturbance or unevenness, thereby improving the adsorption effect of the air intake 2112 on clothing.

[0122] Continue to refer to Figure 10 This application also provides an ironing device 300, including an ironing device 300 body and any of the ironing heads 200 as described in the foregoing embodiments disposed on the ironing device 300 body.

[0123] The overall structure and working principle of the ironing head 200 are the same as those in the aforementioned embodiments, and will not be repeated here.

[0124] Furthermore, since the ironing device 300 adopts the ironing head 200 in the above embodiment, it also has the advantages and benefits brought by the ironing head, which will not be elaborated further here.

[0125] In some examples, the ironing device 300 body comprises a water supply assembly 310, the water supply assembly 310 comprising a water tank 311 and a water pump 312; the water inlet joint 140 in the steam boiler 100 of the ironing head 200 is communicated with the water tank 311 through the water pump 312.

[0126] Thus, in specific implementation, the ironing machine of the embodiment of the present application can be used as a steam ironing machine; when it is needed to iron clothes, the suction assembly 220 is used to provide suction force to the suction port 2112 on the ironing panel 211, so that the ironing panel 211 adsorbs clothes; at the same time, the water pump 312 is used to provide suction force for the water in the water tank 311, so that the water flows into the steam flow channel through the water inlet joint 140 and the water inlet port 1121 of the steam boiler 100, thereby generating steam by using the heating member to heat the water, and the steam passes through the steam flow channel to be sprayed out through the ironing port 2111 on the ironing panel 211, so as to realize steam ironing of the clothes.

[0127] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
