[0061] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiments of the present application will be described in more details below in combination with the drawings in the preferred embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below in combination with the drawings.

[0062] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms “mounting”, “connection”, “connecting” should be understood in a broad sense, for example, can be fixedly connected, can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0064] The terms "first", "second", "third", "fourth" and the like in the specification of the present application and the above drawings are used to distinguish similar objects, and do not necessarily have to describe a particular order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0065] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0066] An iron is a household appliance used to remove wrinkles on clothes and make clothes smooth and flat. The iron usually has an ironing surface, and a user can hold the iron to make the ironing surface contact the clothes to be ironed for ironing.

[0067] 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 the clothes to be ironed through the ironing surface.

[0068] However, in some application scenarios, for example, when the 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, so that the steam can only absorb a small amount of heat from the heating element, and thus the steam temperature in the ironing process is low, which is easy to form condensate at the ironing soleplate, thereby affecting the ironing efficiency. On this basis, the flow path of the steam can be extended by arranging a flow guide member to increase the heat exchange between the steam and the heating element, thereby reducing the steam temperature in the ironing process. However, the extension of the steam path will cause the steam to be led out from the steam hole to lag behind, which will also affect the ironing efficiency and make the user experience poor.

[0069] In view of this, the steam boiler, the ironing head and the ironing device are provided in the embodiments of the present application; the steam boiler is used for the ironing head, and comprises a heating shell and a heating element; the heating shell is provided with a water injection opening; water can be injected into the heating shell through the water injection opening; the heating shell has a first steam passage and a second steam passage; one end of the first steam passage is communicated with the water injection opening, and the other end of the first steam passage is communicated with one end of the second steam passage; the other end of the second steam passage is used for being communicated with an ironing opening of the ironing head.

[0070] By arranging the auxiliary steam passage in the heating shell, and by communicating one end of the auxiliary steam passage with the water injection opening and the other end of the auxiliary steam passage with one of the first steam passage and the second steam passage, part of the water at the water injection opening can flow to the first steam passage and the second steam passage in sequence through the auxiliary steam passage to be heated into steam, or directly flow to the second steam passage to be heated into steam and sprayed from the ironing opening, or by communicating one end of the auxiliary steam passage with one of the first steam passage and the second steam passage and communicating the other end of the auxiliary steam passage with the ironing opening, part of the water at the water injection opening can flow through the first steam passage to be heated into steam or flow through the first steam passage and part of the second steam passage in sequence to be heated into steam and then sprayed from the ironing opening through the auxiliary steam passage, so that the path of part of the steam through the first steam passage or the second steam passage can be shortened, and part of the steam does not need to flow through the first steam passage and the second steam passage completely, so that the flow path is shorter, and then a part of the steam can be quickly sprayed first, and then the subsequent stable steam can be sprayed through the vaporization of the remaining water, which is beneficial to improving the user experience.

[0071] Hereinafter, the present application will be described in detail in conjunction with the drawings and specific embodiments.

[0072] Reference Figures 1 to 7 The steam boiler 100 provided in the embodiments of the present application is used for the ironing head 200, and the steam boiler 100 comprises a heating shell 110 and a heating element 120; the heating shell 110 is provided with a water injection opening 1121; the heating shell 110 has a first steam passage 1011, a second steam passage 1021 and an auxiliary steam passage 114; the water injection opening 1121, the first steam passage 1011, the second steam passage 1021 and an ironing opening 2111 of the ironing head 200 are communicated in sequence; one end of the auxiliary steam passage 114 is communicated with the water injection opening 1121, and the other end of the auxiliary steam passage 114 is communicated with one of the first steam passage 1011 and the second steam passage 1021; or one end of the auxiliary steam passage 114 is communicated with one of the first steam passage 1011 and the second steam passage 1021, and the other end of the auxiliary steam passage 114 is communicated with the ironing opening 2111.

[0073] The heating element 120 is configured to heat the water injected into the first steam passage 1011 and the second steam passage 1021 through the water injection port 1121 to vaporize the water into steam and spray out through the ironing port 2111.

[0074] Specifically, the heating shell 110 serves as an outer shell of the steam boiler 100 to provide a space required for steam generation and flow.

[0075] The heating element 120 is configured to heat the water injected into the first steam passage 1011 and the second steam passage 1021 through the water injection port 1121 to vaporize the water into steam and spray out through the ironing port 2111.

[0076] The ironing port 2111 of the ironing head 200 serves as an outlet of the steam to be aimed at the clothes to be ironed and spray the generated steam onto the clothes to be ironed.

[0077] The embodiment of the present application sequentially connects the water injection port 1121, the first steam passage 1011, the second steam passage 1021 and the ironing port 2111 by setting the first steam passage 1011 and the second steam passage 1021, so that the water injected through the water injection port 1121 is heated by the heating element 120 in the process of sequentially flowing into the first steam passage 1011 and the second steam passage 1021 to spray out from the ironing port 2111, thereby realizing the vaporization of the water.

[0078] The other end of the auxiliary steam passage 114 is connected with the second steam passage 1021, so that part of the water at the water injection port 1121 can flow into the second steam passage 1021 through the auxiliary steam passage 114 to be heated into steam and sprayed out from the ironing port 2111 without flowing through the first steam passage 1011, and the rest of the water flows through the first steam passage 1011, the second steam passage 1021 and the ironing port 2111 in sequence.

[0079] It can be understood that, since part of the water at the water injection port 1121 can flow into the second steam passage 1021 and the ironing port 2111 through the auxiliary steam passage 114 without flowing through the first steam passage 1011, the flow path is short, so that a part of the steam can be quickly sprayed out first, and then the rest of the water is vaporized to realize the subsequent stable spraying of the steam, which is beneficial to improve the user experience.

[0080] In specific implementation, one end of the auxiliary steam passage 114 can be in communication with the first steam passage 1011, and the other end of the auxiliary steam passage 114 can be in communication with the ironing opening 2111. In this way, part of the water at the water injection opening 1121 can be heated into steam through the first steam passage 1011 and then sprayed from the ironing opening 2111 through the auxiliary steam passage 114, without passing through the second steam passage 1021. Thus, the flow path can be shortened, and then part of the steam can be quickly sprayed first, and the subsequent stable steam can be sprayed through the vaporization of the remaining water, which is beneficial to improve the user experience.

[0081] Further, one end of the auxiliary steam passage 114 can be in communication with the water injection opening 1121, and the other end of the auxiliary steam passage 114 can be in communication with the first steam passage 1011, so that part of the water at the water injection opening can flow to the first steam passage 1011 and the second steam passage 1021 in sequence through the auxiliary steam passage 114, be heated into steam, and be sprayed from the ironing opening 2111; or one end of the auxiliary steam passage 114 can be in communication with the second steam passage 1021, and the other end of the auxiliary steam passage 114 can be in communication with the ironing opening 2111, so that part of the water at the water injection opening can flow through the first steam passage 1011 and part of the second steam passage 1021 in sequence, be heated into steam, and be sprayed from the ironing opening 2111 through the auxiliary steam passage 114. In this way, the path of part of the steam passing through the first steam passage 1011 or the second steam passage 1021 can be shortened, so that part of the steam does not need to pass through the first steam passage 1011 and the second steam passage 1021 completely, achieving the purpose of a shorter flow path.

[0082] Reference Figures 4 to 7 In some embodiments, the heat generating shell 110 includes a heat generating seat 111, and the first steam passage 1011 and the second steam passage 1021 are respectively arranged on two opposite surfaces of the heat generating seat 111; the heat generating seat 111 has a communication hole 1111, the other end of the first steam passage 1011 and one end of the second steam passage 1021 are in communication through the communication hole 1111; the first steam passage 1011 has a first communication part 131, the first communication part 131 is adjacent to the communication hole 1111, and the communication hole 1111 and the water injection opening 1121 are in communication through the first communication part 131, and the first communication part 131 and the communication hole 1111 jointly form the auxiliary steam passage 114.

[0083] Thus, the first communication part 131 is one end of the auxiliary steam passage 114, and the communication hole 1111 is the other end of the auxiliary steam passage 114. In use, the first communication part 131 and the communication hole 1111 are adjacent, so that the time for steam flowing in the auxiliary steam passage 114 can be shortened, and the water at the water inlet 1121 can be sequentially flowed to the first communication part 131 and the communication hole 1111, and then heated into steam in the second steam passage 1021, and then sprayed through the ironing port 2111.

[0084] Specifically, the two opposite surfaces of the heating seat 111 are a first surface and a second surface, wherein the first surface is located in the first accommodating cavity 101, and the second surface is located in the second accommodating cavity 102, the first steam passage 1011 is arranged on the first surface, and the second steam passage 1021 is arranged on the second surface.

[0085] Specifically, the two opposite surfaces of the heating seat 111 are a first surface and a second surface, wherein the first surface is located in the first accommodating cavity 101, and the second surface is located in the second accommodating cavity 102, the first steam passage 1011 is arranged on the first surface, and the second steam passage 1021 is arranged on the second surface.

[0086] Specifically, the two opposite surfaces of the heating seat 111 are a first surface and a second surface, wherein the first surface is located in the first accommodating cavity 101, and the second surface is located in the second accommodating cavity 102, the first steam passage 1011 is arranged on the first surface, and the second steam passage 1021 is arranged on the second surface.

[0087] Thus, the steam can flow through the first accommodating cavity 101 and the second accommodating cavity 102 in an overlapping manner, and the flow path is prolonged. When the water is heated by the heating element 120, the water can fully absorb the heat of the heating element 120, which is beneficial to increasing the amount of steam.

[0088] Specifically, the two opposite surfaces of the heating seat 111 are a first surface and a second surface, wherein the first surface is located in the first accommodating cavity 101, and the second surface is located in the second accommodating cavity 102, the first steam passage 1011 is arranged on the first surface, and the second steam passage 1021 is arranged on the second surface.

[0089] Exemplarily, the number of the first steam channels 1011 and the second steam channels 1021 is both set to two, one end of one of the two first steam channels 1011 is communicated with the water injection port 1121, the other end of the one of the two first steam channels 1011 is communicated with one end of one of the two second steam channels 1021 through the first communication hole 1111, the other end of the one of the two second steam channels 1021 is continuously communicated with one end of the other of the two first steam channels 1011 through the second communication hole 1111, the other end of the other of the two first steam channels 1011 is continuously communicated with one end of the other of the two second steam channels 1021 through the third communication hole 1111, and the other end of the other of the two second steam channels 1021 is used to communicate with the ironing port 2111 of the ironing head 200. In this way, the first steam channels 1011 and the second steam channels 1021 are communicated in sequence through the communication holes 1111 to prolong the path of steam flow.

[0090] It can be understood that one of the two first steam channels 1011 is the first steam channel 1011 at the head, and the other of the two second steam channels 1021 is the second steam channel 1021 at the tail.

[0091] Here, Figures 10 to 13 The arrows in the above figure show the flow sequence and path of steam flowing from the first steam channel 1011 at the head to the second steam channel 1021 at the tail in sequence.

[0092] Referring to Figures 6 to 9 Further, the at least three communication holes 1111 include the first communication hole 1112, the first communication part 131 is arranged on the first steam channel 1011 at the head, and the first steam channel 1011 at the head is communicated with the second steam channel 1021 at the head through the first communication hole 1112, the two adjacent second steam channels 1021 are communicated through the second communication part 132, and the first communication part 131 and the second communication part 132 are adjacent to the first communication hole 1112; the first communication part 131, the first communication hole 1112 and the second communication part 132 are communicated in sequence to form the auxiliary steam channel 114.

[0093] In this way, when the second steam channels 1021 are provided with at least two, the auxiliary steam channel 114 formed by the first communication part 131, the first communication hole 1112 and the second communication part 132 enables part of the water at the water injection port 1121 to be sprayed out from the ironing port 2111 without flowing to each second steam channel 1021 in sequence to be heated into steam, which can shorten the flow path of steam in each second steam channel 1021 and ensure that part of the steam generated first can be sprayed out quickly.

[0094] Exemplarily, the second steam passage 1021 is provided with two, Figure 9 The arrows in the figure show the flow path of the water at the water inlet 1121, which is heated in the second steam passage 1021 of the tail part after passing through the first communication hole 1112 and the second communication part 132 in turn, that is, part of the water does not flow through the second steam passage 1021 of the head part, thereby shortening the flow path of the steam in each second steam passage 1021.

[0095] Referring to Figure 4 and Figure 7 In some examples, one of the two opposite surfaces of the heating seat 111 is provided with a meandering flow guide groove, and the other has a meandering flow channel surrounded by the flow guide plate 130, the flow guide groove forms one of the first steam passage 1011 and the second steam passage 1021, and the flow guide plate 130 surrounds the other of the first steam passage 1011 and the second steam passage 1021.

[0096] In this way, the groove wall of the flow guide groove or the flow guide plate 130 can guide the water and steam to flow stably; the meandering design of the flow guide groove or the meandering flow 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 on the basis of ensuring that the steam uniformly takes away the heat of the heating element 120.

[0097] Exemplarily, a meandering flow guide groove can be provided on the first surface of the heating seat 111 located in the first accommodating cavity 101 to form the first steam passage 1011, and the flow guide plate 130 is provided on the second surface of the heating seat 111 located in the second accommodating cavity 102 to surround the meandering flow channel to form the second steam passage 1021.

[0098] Of course, in specific implementation, the flow guide plate 130 can be provided on the first surface of the heating seat 111 located in the first accommodating cavity 101 to surround the meandering flow channel to form the second steam passage 1021; and the meandering flow guide groove can be provided on the second surface of the heating seat 111 located in the second accommodating cavity 102 to form the second steam passage 1021.

[0099] In some embodiments, at least one of the two opposite surfaces of the heating seat 111 is provided with a meandering flow guide groove, and the flow guide groove forms at least one of the first steam passage 1011 and the second steam passage 1021; or, at least one of the two opposite surfaces of the heating seat 111 has a meandering flow channel surrounded by the flow guide plate 130, and the flow guide plate 130 surrounds at least one of the first steam passage 1011 and the second steam passage 1021.

[0100] In this way, the meandering flow guide grooves can be arranged on the two opposite surfaces of the heating seat 111, or the meandering flow channels surrounded by the flow guide plates 130 can be arranged on the two opposite surfaces of the heating seat 111, and when the number of the first steam passages 1011 and the second steam passages 1021 is at least two, the design of the heating seat 111 can be simplified, the structural consistency of the first steam passages 1011 and the second steam passages 1021 can be improved, and the production and processing are facilitated.

[0101] In specific examples, at least one of the first communication part 131 and the second communication part 132 is a second through hole arranged on the flow guide groove or the flow guide plate 130; or at least one of the first communication part 131 and the second communication part 132 is a notch arranged on the flow guide groove or the flow guide plate 130.

[0102] In this way, the auxiliary steam passage 114 and the water inlet 1121, and the auxiliary steam passage 114 and the second steam passage 1021 are in communication through the design of the second through hole or the notch, and meanwhile, the structure of the first communication part 131 and the second communication part 132 is simplified, which facilitates the overall compactness of the steam boiler 100.

[0103] Referring to Figures 10 to 13 In some examples, each first steam passage 1011 is sequentially arranged around the periphery of the heating seat 111 to the middle of the heating seat 111, and the first steam passage 1011 at the head is adjacent to the periphery of the heating seat 111; and / or each second steam passage 1021 is sequentially arranged around the periphery of the heating seat 111 to the middle of the heating seat 111, and the second steam passage 1021 at the tail is located in the middle of the heating seat 111.

[0104] In this way, by optimizing the layout of each first steam passage 1011, each first steam passage 1011 can more completely cover the first accommodating cavity 101 of the heating shell 110, and / or by optimizing the layout of each second steam passage 1021, each second steam passage 1021 can more completely cover the second accommodating cavity 102 of the heating shell 110. When the heating element 120 is located in the heating shell 110 to heat the water, the steam can more fully contact the heating element 120 to uniformly take away the heat of the heating element 120, and the local high temperature phenomenon of the steam boiler 100 as a whole can be reduced.

[0105] Referring to Figures 2 to 7In some examples, the heat generating shell 110 further comprises a cover plate 112; the cover plate 112 is arranged on the heat generating base 111, and the cover plate 112 and the heat generating base 111 jointly define the first accommodating cavity 101; the water injection port 1121 is arranged on the cover plate 112, and the first steam passage 1011 is arranged in the first accommodating cavity 101; the heat generating base 111 away from the cover plate 112 defines the second accommodating cavity 102, and the second steam passage 1021 is arranged in the second accommodating cavity 102, and the second accommodating cavity 102 is used to cover the ironing port 2111.

[0106] In this way, by the combined design of the heat generating base 111 and the cover plate 112, the space required for steam generation and flow is constructed, so as to facilitate the arrangement of the first steam passage 1011 and the second steam passage 1021 therein, which is beneficial to make the steam boiler 100 more compact, facilitating user operation and storage; in specific implementation, the water injection port 1121 is arranged on the cover plate 112, which can make it away from the heat generating area, and can reduce the risk of water leakage at the water injection port 1121 due to high temperature.

[0107] In specific implementation, as shown in Figure 2 , the cover plate 112 can be connected with the heat generating base 111 through a screw 113.

[0108] Referring to Figure 2 , in some examples, the steam boiler 100 further comprises a temperature control device 230; the temperature control device 230 is electrically connected with the heat generating element 120, and the temperature control device 230 is used to detect the temperature in the heat generating shell 110 and control the opening of the heat generating element 120 according to the temperature.

[0109] In this way, by the arrangement of the temperature control device 230, the temperature stability in the steam generation process is improved, the stable output of steam is realized under the heating action of the heat generating element 120, and the ironing effect can be ensured.

[0110] Specifically, the temperature control device 230 is used to monitor the temperature change in the heat generating shell 110 in real time, to ensure that the temperature always remains within a set range; for example, when the temperature exceeds the preset range, the temperature control device 230 can automatically cut off the power supply of the heat generating element 120 to prevent overheating; when the temperature is lower than the preset range, the heat generating element 120 is started to maintain the required working temperature.

[0111] It can be understood that the preset range is the temperature value required for stable steam generation, and the preset range can be set according to actual conditions, which is not limited in the embodiments of the present application.

[0112] The embodiment of the present application reduces the need for manual intervention by setting the temperature control 230, so that the heating element 120 only works when necessary, reduces unnecessary energy consumption, improves user experience and energy utilization; At the same time, it can reduce the aging and failure of the heating element 120 under long-time high-temperature operation, and prolong the service life of the steam boiler 100 as a whole.

[0113] In some examples, the steam boiler 100 further comprises a fuse 240 connected with the heating element 120.

[0114] In this way, the fuse 240 ensures that the heating circuit works within a safe range, reduces failures caused by current fluctuations, and ensures the stability and reliability of the steam boiler 100.

[0115] Specifically, when the heating circuit is short-circuited or other abnormal conditions cause the current to be too large, the fuse 240 can be fused in time to protect the heating element 120 and other components from damage and reduce safety hazards caused by long-time overheating.

[0116] Referring to Figure 3 and Figure 14 , the embodiment of the present application provides an ironing head 200, which comprises an ironing head body 210 and a steam boiler 100 as in any of the preceding embodiments disposed on the ironing head body 210; the other end of the second steam passage 1021 of the steam boiler 100 is in communication with the ironing port 2111 of the ironing head body 210.

[0117] Wherein, the overall structure, working principle of the steam boiler 100 and the same in the preceding embodiments, will not be repeated here.

[0118] Further, since the ironing device 300 adopts the ironing head 200 in the above-mentioned embodiments, it also has the advantages and benefits brought by the above-mentioned ironing head 200 accordingly, which will not be repeated here.

[0119] Illustratively, 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 covered on the ironing panel 211, and the ironing panel 211 and the protective cover 212 together form an installation cavity 201, and the heating shell 110 of the steam boiler 100 is located in the installation cavity 201.

[0120] Referring to Figure 14 and Figure 15 , the embodiment of the present application further provides an ironing device 300, which comprises an ironing device body and an ironing head 200 as in the preceding embodiments disposed on the ironing device body.

[0121] Wherein, the overall structure, working principle of the ironing head 200 and the same in the preceding embodiments, will not be repeated here.

[0122] Further, since the ironing device 300 adopts the ironing head 200 in the above-mentioned embodiments, it also has the advantages and benefits brought by the ironing head 200 accordingly, which will not be described here.

[0123] In a specific implementation, the ironing device body includes a water supply assembly 310, which includes a water tank 311 and a water pump 312; the water inlet 1121 in the steam boiler 100 of the ironing head 200 is in communication with the water tank 311 through the water pump 312.

[0124] In the ironing head body 210, an air suction port 2112 in communication with the mounting cavity 201 can be formed on the ironing panel 211, and a suction assembly 220 can also be arranged in the mounting cavity 201. During the ironing process, the suction assembly 220 generates negative pressure to suck air through the air suction port 2112, so that the clothes to be ironed are adsorbed on the ironing panel 211, which can ensure the ironing effect.

[0125] In this way, the ironing device 300 of the embodiments of the present application can be used as a steam ironing machine. When the clothes need to be ironed, the suction assembly 220 is used to provide suction force to the air suction port 2112 on the ironing panel 211 to make the ironing panel 211 adsorb the clothes; at the same time, the water pump 312 is used to provide suction force to the water in the water tank 311, so that the water flows into the first steam channel 1011 and the second steam channel 1021 through the water inlet 1121 of the steam boiler 100, and the water is heated by the heating element 120 to generate steam, which is sprayed out of the ironing port 2111 of the ironing head body 210 to realize ironing of the clothes.

[0126] As shown in the example, Figure 15 The ironing device body can also include an electronic board 320, which is used to manage and coordinate the functions and operations of the ironing device 300. For example, when the water in the water tank 311 is insufficient, the electronic board 320 senses and avoids dry burning by turning off the heating element 120, thereby protecting the internal components of the ironing device 300.

[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 they can still modify the technical solutions described in the foregoing embodiments, or make equivalent replacement to some 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.
