Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a handheld steam iron. Background Art

[0002] A steam iron, also known as a hanging iron or a standing iron, can iron clothes while the clothes are in a hanging state. The high-temperature and high-pressure water vapor generated inside the steam iron continuously contacts the clothes and fabrics to soften the fiber tissues of the clothes and fabrics, and the clothes can be made smoother by means of "pulling", "pressing" and "spraying".

[0003] In order to reduce the occupied space of the steam iron and improve the convenience of using the steam iron, the existing steam irons are gradually tending to be miniaturized, and small handheld steam irons are becoming more and more common in life. Specifically, the handheld steam iron includes a steam iron body. A steam hole is provided on the shell of the steam iron body. Components such as a water tank, a water pump and a heating element are arranged inside the steam iron body. The water in the water tank is pumped to the heating element by the water pump, and the heating element heats the water to form water vapor, and the water vapor is sprayed out through the steam hole; among them, in order to realize the flat ironing function of the handheld steam iron, a flat ironing base is usually installed at one end of the steam iron body where the steam hole is provided. An air outlet hole is opened at a position corresponding to the steam hole of the steam iron body on the flat ironing base, and the steam is sprayed onto the clothes through the air outlet hole to realize the flat ironing operation of the clothes.

[0004] However, in the prior art, when the handheld steam iron with the flat ironing function performs the flat ironing operation, the ironing effect is poor, the ironing efficiency is low, and the user experience is poor. Summary of the Invention

[0005] The present invention provides a handheld steam iron, which has a better ironing effect and a higher ironing efficiency during the flat ironing operation, and can improve the user experience.

[0006] The present invention provides a handheld steam iron, which includes a steam iron body and an ironing base. The steam iron body includes a handle and a spray head connected to one end of the handle. A plurality of steam holes are provided at the end of the spray head; the ironing base is detachably connected to the end of the spray head. The surface of the ironing base connected to the spray head has an air inlet hole corresponding to and communicating with the steam hole. A heating cavity is provided inside the ironing base. The surface of the ironing base facing away from the spray head is an ironing surface, and a plurality of air outlet holes are spaced apart on the ironing surface. The air inlet hole and the air outlet hole are both communicated with the heating cavity.

[0007] The handheld steam iron provided by the present invention can achieve the flat ironing function of the handheld steam iron by setting an ironing base detachably connected to the steam iron body. Among them, the ironing base is connected to the end of the nozzle of the steam iron body. By setting a heating cavity in the ironing base, the water vapor generated by the nozzle enters the heating cavity through the steam inlet holes of the ironing base. The heating cavity can reheat the water vapor, and by arranging a plurality of steam outlet holes at intervals on the ironing surface of the ironing base, the reheated water vapor is ejected outward through these plurality of steam outlet holes, which can improve the ironing efficiency during the flat ironing operation of the handheld steam iron, enhance the ironing effect, and further improve the user experience.

[0008] In a possible implementation manner, the plurality of steam outlet holes are evenly spaced on the ironing surface. This can further increase the coverage area of the steam ejected by the ironing base and improve the ironing efficiency of the ironing base.

[0009] In a possible implementation manner, the ironing base includes an upper cover assembly and a bottom cover that are snap-fitted to each other. The nozzle is detachably connected to the upper cover assembly, and the side of the bottom cover facing away from the nozzle is the ironing surface.

The heating tube is connected to the bottom cover through the fixing part, and the heating tube is used to heat the steam entering from the steam iron body. The heating tube generates heat to reheat the water vapor, and the fixing part fixes the heating tube on the bottom cover.

[0013] In a possible implementation manner, the fixing part wraps around the outside of the heating tube and is integrally connected to the bottom cover. In this way, the heating tube can be firmly connected to the bottom cover, and the heat of the heating tube is conducted outward through the fixing part, which can improve the heat conduction effect of the heating part.

[0014] In a possible implementation manner, the heating cavity includes a first steam chamber and a second steam chamber that communicate with each other. The second steam chamber surrounds the outside of the first steam chamber, and the heating part is spaced between the first steam chamber and the second steam chamber.

[0015] In this way, the water vapor can pass through the first steam chamber and the second steam chamber in sequence, which can increase the flow rate of the water vapor. By arranging the heating part between the first steam chamber and the second steam chamber, the water vapor can be continuously heated by the heating part during the flow process, so as to improve the heating efficiency and heating effect.

[0016] In a possible implementation, a first isolating portion extending toward the heating portion is provided on the heat conducting plate, and the first isolating portion is in contact with the heating portion; a second isolating portion extending toward the heat conducting plate is provided on the bottom cover, and the second isolating portion is arranged outside the heating portion, and the second isolating portion is in contact with the heat conducting plate;

[0017] The first steam chamber corresponds to a region formed inside the first isolating portion, and the second steam chamber corresponds to a region between the first isolating portion and the second isolating portion.

[0018] In a possible implementation, the multiple steam spray holes on the nozzle include steam spray holes corresponding to the outer side of the first steam chamber, and the upper cover is provided with a blocking column, which is used to block the steam spray holes located outside the first steam chamber.

[0019] By blocking the steam holes corresponding to the outside of the first steam chamber through the blocking column of the upper cover, all the steam can enter the first steam chamber, thereby guiding the flow of water vapor and preventing the steam sprayed from the nozzle from leaking outward from the steam holes corresponding to the outside of the first steam chamber.

[0020] In a possible implementation manner, a side of the upper cover facing the nozzle has a mounting groove, the mounting groove matches the contour of the end of the nozzle, and the end of the nozzle is inserted into the mounting groove.

[0021] In a possible implementation, the heating tube is connected with a conductive needle, the conductive needle extends toward the upper cover, a through hole is provided on the heat conducting plate corresponding to the conductive needle, the upper cover is provided with an isolation column extending into the through hole, the isolation column has a through hole, and the conductive needle passes through the through hole to be electrically connected to the garment steamer body. The electrical connection between the heating tube and the garment steamer body is achieved through the conductive needle, and then the heating of the heating tube is controlled by the garment steamer body.

[0022] In a possible implementation manner, the gap between the conductive needle and the through hole is filled with sealant, so as to prevent steam from leaking out of the through hole.

[0023] In a possible embodiment, the nozzle includes a main shell and a nozzle end cover connected to the end of the main shell, and the steam injection hole is provided on the nozzle end cover; the inner wall of the nozzle end cover is provided with a conductive spring sheet, and the conductive needle extends into the nozzle end cover and contacts the conductive spring sheet, so as to be electrically connected to the garment steamer body through the conductive spring sheet. By providing the conductive spring sheet in contact with the conductive needle, the electrical connection between the heating tube and the garment steamer body is achieved.

[0024] In a possible implementation, the other end of the handle can be cooperatively connected to a charging base. A rechargeable battery is provided inside the clothes hanger iron body. The clothes hanger iron body can be detached from the charging base for ironing work, or the clothes hanger iron body can be connected to the charging base for ironing work.

[0025] By connecting the charging base to an external power supply, the operation of the clothes hanger iron body can be directly controlled. Meanwhile, the charging base can charge the rechargeable battery, so that the clothes hanger iron body can be detached from the charging base and its operation can be controlled by the discharge of the rechargeable battery.

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Existing handheld garment steamers with flat ironing function connect an ironing board capable of flat ironing to the garment steamer body. Steam ejected from the steam holes of the garment steamer body is ejected outward through the steam outlet holes on the ironing board. The flat ironing function of the clothes is achieved through the contact between the ironing board and the clothes in the horizontal direction.

[0051] However, in the existing handheld garment steamers connected to the ironing board, the steam outlet holes on the ironing board are usually arranged corresponding to the steam spray holes on the garment steamer body, and the steam outlet holes are concentrated in a certain area of ​​the ironing board. The ironing board only serves as a channel for the steam sprayed from the garment steamer body, and the steam is sprayed outward through the ironing board. In this way, when the handheld garment steamer is used for flat ironing, the steam temperature is low and the steam is only sprayed outward through a local area of ​​the ironing board, so the ironing effect is poor, the ironing efficiency is low, and the user experience is poor.

[0052] Therefore, the present embodiment provides a handheld garment steamer with a flat ironing function, so as to improve the ironing effect of the handheld garment steamer and the ironing efficiency when the handheld garment steamer performs a flat ironing operation, thereby improving the user experience.

[0053] Figure 1Schematic structural diagram of the handheld steam iron provided by an embodiment of the present invention; Figure 2 Side view of the handheld steam iron provided by an embodiment of the present invention; Figure 3 Exploded view of the handheld steam iron provided by an embodiment of the present invention; Figure 4 Exploded view of the ironing base provided by an embodiment of the present invention.

[0054] As Figures 1 to 4 shown, this embodiment provides a handheld steam iron, which includes a steam iron body 1 and an ironing base 2. The steam iron body 1 includes a handle 11 and a nozzle 12 connected to one end of the handle 11. A plurality of steam holes 1211 are provided at the end of the nozzle 12; the ironing base 2 is detachably connected to the end of the nozzle 12. One side of the ironing base 2 connected to the nozzle 12 has steam inlet holes 211 corresponding to the steam holes 1211. A heating chamber 23 is provided inside the ironing base 2. The side of the ironing base 2 facing away from the nozzle 12 is an ironing surface 221. A plurality of steam outlet holes 222 are distributed at intervals on the ironing surface 221. Both the steam inlet holes 211 and the steam outlet holes 222 are communicated with the heating chamber 23.

[0055] As Figures 1 to 3 shown, the handheld steam iron provided in this embodiment is a handheld steam iron that can perform flat ironing operations. This handheld steam iron can not only achieve the hanging ironing function but also the flat ironing function.

[0056] Specifically, the handheld steam iron includes a steam iron body 1 and an ironing base 2. The steam iron body 1 can be used alone, and the hanging ironing function can be achieved through the steam iron body 1; the ironing base 2 is detachably connected to the steam iron body 1. When flat ironing operations are required, the ironing base 2 is connected to the steam iron body 1, and steam is sprayed onto the clothes through the ironing base 2 to achieve the flat ironing function.

[0057] The steam iron body 1 includes a handle 11 and a nozzle 12. The handle 11 is for the user to hold. The nozzle 12 is connected to one end of the handle 11. A plurality of steam holes 1211 are provided at the end of the nozzle 12. High-temperature and high-pressure water vapor can be generated inside the steam iron body 1, and the water vapor is sprayed out through the steam holes 1211 at the end of the nozzle 12. When performing hanging ironing operations, the steam iron body 1 can be used alone, and the clothes are moistened by the water vapor sprayed out through the steam holes 1211 at the end of the nozzle 12 to achieve hanging ironing of the clothes.

[0058] Figure 5 Exploded view of the steam iron body provided by an embodiment of the present invention; Figure 6 Structural diagram of the nozzle end cap from one perspective provided by an embodiment of the present invention; Figure 7 Structural diagram of the nozzle end cap from another perspective provided by an embodiment of the present invention.

[0059] As Figures 5 to 7As shown, it should be noted that in this embodiment, the handle 11 and the nozzle 12 can be integrally formed, or the nozzle 12 and the handle 11 can be detachably connected, so as to facilitate the maintenance or replacement of the components inside the clothes hanger iron body 1.

[0060] Among them, the nozzle 12 can include a main housing and an end cap. The main housing is connected to the handle 11. The nozzle end cap 121 is detachably connected to one end of the main housing away from the handle 11. The steam holes 1211 on the nozzle 12 are provided on the nozzle end cap 121.

[0061] In addition, components such as a water tank (not shown in the figure), a water pump (not shown in the figure), and a heating element 122 are usually provided inside the clothes hanger iron body 1. Among them, the water tank is used to store the clean water required for ironing clothes. The water pump is connected between the water tank and the heating element 122. The water pump provides power to transport the clean water in the water tank to the heating element 122. Then, the heating element 122 heats the clean water to form high-temperature and high-pressure steam. The steam is discharged from the heating element 122 and sprayed out through the steam holes 1211 on the nozzle 12.

[0062] Components such as the water tank, the water pump, and the heating element 122 are accommodated in the handle 11 and the nozzle 12. For example, the water tank and the water pump are accommodated in the handle 11, and the heating element 122 is accommodated in the nozzle 12. The steam discharge end of the heating element 122 can correspond to the steam holes 1211 of the nozzle 12. In this way, the steam discharged from the heating element 122 can reach the steam holes 1211 of the nozzle 12 through a shorter path.

[0063] Such as Figures 1 to 3 As shown, in some embodiments, the handheld clothes hanger iron can be connected to an external power supply to work, and the handheld clothes hanger iron can also work without being connected to the external power supply, so as to improve the flexibility and operation convenience of the handheld clothes hanger iron and enhance the user experience.

[0064] Specifically, in this embodiment, the other end of the handle 11 of the clothes hanger iron body 1 can be cooperatively connected with the charging base 14. The charging base 14 is connected to the external power supply through an electric connection wire. When the charging base 14 is connected to the external power supply, the charging base 14 can directly control the operation of the clothes hanger iron body 1; and a charging battery is provided inside the clothes hanger iron body 1. When the charging base 14 is connected to the external power supply, the charging battery can be charged at the same time. When the charging battery has sufficient power, the clothes hanger iron body 1 can be detached from the charging base 14, and the charging battery provides electrical energy for the clothes hanger iron body 1 to control its operation.

[0065] Among them, when the ironing machine body 1 is connected to the charging base 14 and the charging base 14 is connected to an external power supply, the charging base 14 can directly deliver the current of the external power supply to the ironing machine body 1. For example, the external power supply directly supplies power to the water pump in the ironing machine body 1, and the water pump transports the cleaning water in the water tank to the heating element 122. At the same time, the external power supply supplies power to the heating element 122, and controls the heating element 122 to heat the cleaning water into water vapor. At this time, the ironing machine body 1 is connected to the external power supply through the charging base 14, which is equivalent to the "wired connection" use state of the handheld ironing machine.

[0066] When the rechargeable battery has sufficient power, the ironing machine body 1 can work independently. When the ironing machine body 1 is not connected to the charging base 14, the rechargeable battery discharges to supply power to the water pump, and the water pump transports the cleaning water in the water tank to the heating element 122. The heating element 122 can rely on the heat stored when the ironing machine body 1 is connected to the charging base 14 to continue heating the cleaning water to form water vapor; or the rechargeable battery can store a large amount of power. While supplying power to the water pump, it can also supply power to the heating element 122, so that the heating element 122 continuously heats the cleaning water into water vapor. At this time, the ironing machine body 1 works independently away from the charging base 14, which is equivalent to the "wireless connection" use state of the handheld ironing machine.

[0067] Therefore, the handheld ironing machine provided in this embodiment can be used in both "wired connection" and "wireless connection" modes. The use method is more flexible, and by connecting the ironing machine body 1 to the charging base 14 or disconnecting it from the charging base 14, the above two use modes can be switched, and the operation is more convenient, which can improve the user experience.

[0068] As Figure 5 shown, for the electrical connection between the handle 11 of the ironing machine body 1 and the charging base 14, in a specific embodiment, the other end of the handle 11 can be connected with a charging part 13, and the charging part 13 is used for electrical connection with the charging base 14. By connecting the charging part 13 to the end of the handle 11 facing away from the nozzle 12 and connecting the charging part 13 to the charging base 14, the electrical connection between the ironing machine body 1 and the charging base 14 is realized.

[0069] Exemplarily, one end of the charging part 13 facing the charging base 14 can have a male plug, while one end of the charging base 14 facing the charging part 13 has a female socket. Through the mating connection of the male plug and the female socket, the electrical connection between the ironing machine body 1 and the charging base 14 is realized.

[0070] As Figures 1 to 3As shown, when a flat ironing operation is required, the ironing base 2 is connected to the body 1 of the hanging iron. Specifically, the ironing base 2 is connected to the end of the spray head 12 where the steam holes 1211 are provided, and an air inlet hole 211 is provided on the surface of the ironing base 2 connected to the spray head 12. The air inlet hole 211 is correspondingly communicated with the steam holes 1211 of the spray head 12, so that the water vapor generated by the spray head 12 enters the ironing base 2 through the air inlet hole 211.

[0071] During the process of the water vapor entering the ironing base 2 from the spray head 12, its temperature will drop. If the temperature drops, it is possible that the water vapor condenses in the ironing base 2, or the water vapor does not condense, but its temperature drops and the movement speed decreases, which will also reduce the ironing effect on the clothes.

[0072] In view of this, the ironing base 2 of this embodiment has a heating chamber 23. After the water vapor coming out of the spray head 12 enters the heating chamber 23 in the ironing base 2, the heating chamber 23 reheats the water vapor, which can maintain the temperature of the water vapor or further increase the temperature of the water vapor. After the water vapor is reheated, it is ejected outward from the steam holes 222 provided on the ironing surface 221 of the ironing base 2. In this way, the water vapor ejected from the ironing base 2 has a higher temperature and movement speed, which can improve the ironing effect on the clothes.

[0073] At the same time, in order to improve the ironing efficiency of the clothes, a plurality of steam holes 222 are provided on the ironing surface 221 of the ironing base 2, that is, the side of the ironing base 2 facing away from the spray head 12. The plurality of steam holes 222 are spaced apart on the ironing surface 221. In this way, the overall area occupied by the steam holes 222 is relatively large, and the coverage area of the water vapor ejected from the steam holes 222 is relatively wide. This can expand the range of the water vapor ejected by the ironing base 2 and improve the spraying uniformity of the water vapor, thereby further improving the ironing efficiency and enhancing the ironing effect.

[0074] Therefore, in this embodiment, by providing a heating chamber 23 in the ironing base 2 and arranging a plurality of steam holes 222 at intervals on the ironing surface 221 of the ironing base 2, the ironing efficiency during the flat ironing operation of the handheld hanging iron can be improved, the ironing effect can be enhanced, and thus the user experience can be improved.

[0075] As Figure 2 shown, in a possible implementation manner, the plurality of steam holes 222 can be evenly spaced on the ironing surface 221 of the ironing base 2. By making the steam holes 222 evenly spaced on the ironing surface 221 of the ironing base 2, on the one hand, the overall coverage area of the steam holes 222 can be increased, thereby expanding the range of the water vapor sprayed by the ironing base 2 and improving the ironing efficiency; on the other hand, the uniformity of the water vapor sprayed by the ironing base 2 can be enhanced, and the ironing effect can be improved.

[0077] As Figure 4 As shown, for the structure of the ironing base 2, specifically, the ironing base 2 may include an upper cover assembly and a bottom cover 22 that are snap-fitted together. The nozzle 12 is detachably connected to the upper cover assembly. The side of the bottom cover 22 facing away from the nozzle 12 is the ironing surface 221.

[0078] In this embodiment, the ironing base 2 is formed by snap-fitting the upper cover assembly and the bottom cover 22. The upper cover assembly and the bottom cover 22 jointly enclose an accommodation space of the ironing base 2, and the heating chamber 23 is formed in this accommodation space. Among them, the ironing base 2 is detachably connected to the nozzle 12 through the upper cover assembly; the bottom cover 22 is disposed opposite to the upper cover assembly, the ironing surface 221 corresponds to the side of the bottom cover 22 facing away from the nozzle 12, and the steam outlet hole 222 is disposed on the side of the bottom cover 22 facing away from the nozzle 12.

[0079] Among them, the upper cover assembly includes an upper cover 21. The upper cover 21 and the bottom cover 22 are snap-fitted together to form the overall appearance structure of the ironing base 2. The upper cover 21 faces the nozzle 12, the upper cover 21 and the nozzle 12 are detachably connected, and the steam inlet hole 211 of the ironing base 2 is disposed on the upper cover 21.

[0080] The steam sprayed by the nozzle 12 enters the heating chamber 23 of the ironing base 2 through the steam inlet hole 211 of the upper cover 21 of the ironing base 2, and after being reheated in the heating chamber 23, it is ejected from the steam outlet hole 222 of the bottom cover 22 of the ironing base 2.

[0081] Since the heating chamber 23 is formed in the accommodation space enclosed by the upper cover 21 and the bottom cover 22 of the ironing base 2, and the upper cover 21 is directly connected to the nozzle 12, the outer surface of the upper cover 21 faces the handle 11, and it is easy for the user to touch the upper cover 21 during operation. In order to prevent the heat of the high-temperature steam generated in the heating chamber 23 from being transferred to the upper cover 21, resulting in injury to the user or reducing the use experience, in a possible implementation manner, the ironing base 2 may further include a heat conducting plate 24. The heat conducting plate 24 is located between the upper cover 21 and the bottom cover 22, and the heat conducting plate 24 and the bottom cover 22 jointly enclose the heating chamber 23.

[0082] By providing a heat conducting plate 24 between the upper cover 21 and the bottom cover 22, a closed heating chamber 23 is formed by enclosing the heat conducting plate 24 and the bottom cover 22, which can better retain the heat in the heating chamber 23 and prevent heat from dissipating to the side of the upper cover 21. Among them, the heat conducting plate 24 can be made of a metal material with good heat conductivity. For example, the heat conducting plate 24 can be an aluminum plate.

[0083] Since the user is likely to touch the upper cover 21, the upper cover 21 can be made of a low heat conductivity material such as plastic. The heat conducting plate 24 is used to concentrate the heat in the heating chamber 23, and the low heat transfer performance of the upper cover 21 ensures the safety of the user during use.

[0084] As Figure 4 and Figure 9 shown, in this embodiment, the heat conducting plate 24 can have a plurality of communication holes 241, and the plurality of communication holes 241 correspond to at least some of the steam inlet holes 211 one by one. By providing the communication holes 241 on the heat conducting plate 24, the communication holes 241 are used to connect the heating chamber 23 and the steam inlet holes 211 on the upper cover 21, so that the water vapor entering the upper cover 21 through the nozzle 12 enters the heating chamber 23 through the communication holes 241 and is reheated.

[0085] Among them, the communication holes 241 can include a plurality, and the plurality of communication holes 241 are arranged corresponding to the heating chamber 23, that is, the communication holes 241 are located at the part of the heat conducting plate 24 that forms the heating chamber 23. It can be understood that the steam inlet holes 211 on the upper cover 21 can be arranged only corresponding to the heating chamber 23. At this time, the communication holes 241 on the heat conducting plate 24 can correspond to all the steam inlet holes 211 on the upper cover 21 one by one; or, the steam inlet holes 211 on the upper cover 21 include the steam inlet holes 211 located outside the heating chamber 23. At this time, the communication holes 241 on the heat conducting plate 24 can only correspond to the steam inlet holes 211 corresponding to the heating chamber 23 one by one.

[0086] Specifically, as Figure 4 and Figure 8 shown, the heating chamber 23 can have a heating part 25, and the heating part 25 can include a heating tube 251 and a fixing part 252. The heating tube 251 is connected to the bottom cover 22 through the fixing part 252, and the heating tube 251 is used to heat the steam entering from the ironing machine body 1.

[0087] In this embodiment, the steam entering the heating chamber 23 is reheated specifically by the heating part 25 provided in the heating chamber 23. The heating part 25 specifically includes a heating tube 251 and a fixing part 252. The heating tube 251 is used to generate heat to heat the steam, and the fixing part 252 is used to fix the heating tube 251 on the bottom cover 22.

[0088] The fixing part 252 can be, for example, a fixing ring sleeved on the outer wall of the heating tube 251, and screws or rivets that connect the fixing ring to the bottom cover 22, etc. Among them, in order to improve the heating effect of the heating part 25, in a possible implementation manner, the fixing part 252 can be wrapped outside the heating tube 251 and connected to the bottom cover 22 as an integral structure.

[0089] Specifically, the fixing part 252 can be made of a metal material with good thermal conductivity, and the fixing part 252 is wrapped outside the heating tube 251 and forms an integral structure with the heating tube 251, and this integral structure is directly fixed on the bottom cover 22. For example, the fixing part 252 is made of aluminum, and the fixing part 252 can be wrapped outside the heating tube 251 and connected to the bottom cover 22 as an integral structure by die-casting. In this way, the fixing part 252 is in close contact with the heating tube 251 and has good thermal conductivity, and can quickly transfer the heat generated by the heating tube 251 to the water vapor in the heating cavity 23 by heat conduction, so as to improve the heat conduction effect of the heating part 25.

[0090] To further improve the heating effect of the heating cavity 23, as Figure 8 shown, in a possible implementation manner, the heating cavity 23 can include a first steam chamber 231 and a second steam chamber 232 that communicate with each other. The second steam chamber 232 surrounds the outside of the first steam chamber 231, and the heating part 25 is spaced between the first steam chamber 231 and the second steam chamber 232.

[0091] By dividing the heating cavity 23 into a first steam chamber 231 and a second steam chamber 232, the first steam chamber 231 and the second steam chamber 232 communicate with each other, and the second steam chamber 232 is located on both sides of the first steam chamber 231. In this way, the water vapor can move along the flow direction formed between the first steam chamber 231 and the second steam chamber 232 in the heating cavity 23, so as to increase the movement speed of the water vapor.

[0092] Specifically, the communication holes 241 on the heat conducting plate 24 can be arranged corresponding to the first steam chamber 231, and the steam outlet holes 222 on the bottom cover 22 can be arranged corresponding to the second steam chamber 232. In this way, the water vapor first enters the first steam chamber 231, then flows from the first steam chamber 231 to the second steam chamber 232, and then is discharged from the steam outlet holes 222, so as to form an orderly water vapor flow direction in the heating cavity 23. In this way, the flow speed of the water vapor can be increased, and the heating efficiency and heating effect of the heating cavity 23 can be improved.

[0093] Among them, the heating part 25 is spaced between the first steam chamber 231 and the second steam chamber 232, so that when the water vapor enters the first steam chamber 231 and flows into the second steam chamber 232, the water vapor always flows around the heating part 25. In this way, the heating part 25 can continuously transfer heat to the water vapor, heating the water vapor more quickly and durably, and further improving the heating effect of the heating chamber 23.

[0094] As Figure 8 , Figure 9 and Figure 13 shown, for forming the first steam chamber 231 and the second steam chamber 232 in the heating chamber 23, in a specific embodiment, the heat conducting plate 24 may be provided with a first isolation part 242 extending towards the heating part 25, and the first isolation part 242 abuts against the heating part 25; the bottom cover 22 may be provided with a second isolation part 223 extending towards the heat conducting plate 24, the second isolation part 223 surrounds the outside of the heating part 25, and the second isolation part 223 abuts against the heat conducting plate 24; the first steam chamber 231 corresponds to the area formed inside the first isolation part 242, and the second steam chamber 232 corresponds to the area between the first isolation part 242 and the second isolation part 223.

[0095] By providing the first isolation part 242 on the side of the heat conducting plate 24 facing the heating chamber 23, the first isolation part 242 extends towards the heating part 25, and the first isolation part 242 abuts against the heating part 25, so that the inner area surrounded by the first isolation part 242 and the heating part 25 can form the first steam chamber 231; by providing the second isolation part 223 on the inner wall of the bottom cover 22, the second isolation part 223 surrounds the outside of the heating part 25, and the second isolation part 223 extends towards the heat conducting plate 24 and abuts against the heat conducting plate 24, so that the area between the second isolation part 223 and the heating part 25 can form the second steam chamber 232.

[0096] Exemplarily, as Figure 8 shown, taking the heating tube 251 as a "U-shaped" heating tube 251 as an example, the heating part 25 as a whole can be in a "U-shaped" shape, the first isolation part 242 can be a "U-shaped" isolation wall corresponding to the heating tube 251, the second isolation part 223 is a "U-shaped" isolation wall surrounding the outside of the heating tube 251, the first steam chamber 231 is the middle "U-shaped" area, and the second steam chamber 232 is a "U-shaped" annular area surrounding the first steam chamber 231.

[0097] It can be understood that the heating tube 251 can also be in other shapes. For example, it includes two straight heating tubes 251 arranged in parallel at intervals. The first steam chamber 231 is formed between the two heating tubes 251, and the second steam chamber 232 is formed between the two heating tubes 251 and the corresponding second isolation part 223 on the side; or, the heating tube 251 is in other shapes such as "V-shaped", and the present embodiment does not make specific limitations on this.

[0098] As Figure 6 , Figure 7 and Figure 10 , Figure 11 shown, in some embodiments, the plurality of steam holes 1211 on the nozzle 12 may include steam holes 1211 correspondingly located outside the first steam chamber 231. The upper cover 21 is provided with a plug post 212, and the plug post 212 is used to block the steam holes 1211 located outside the first steam chamber 231.

[0099] When the handheld steam iron realizes the hanging ironing function, in order to expand the coverage range of the water vapor ejected from the nozzle 12 and improve the spraying uniformity of the nozzle 12, as Figure 6 and Figure 7 shown, in this embodiment, the plurality of steam holes 1211 provided on the nozzle 12 may be evenly spaced between the two ends of the nozzle end cap 121. Among them, the steam holes 1211 near the two ends of the nozzle end cap 121 may be correspondingly located outside the first steam chamber 231 of the heating chamber 23.

[0100] Since the steam inlet hole 211 of the upper cover 21 of the ironing base 2 is used to allow water vapor to enter the first steam chamber 231 of the heating chamber 23, and the steam holes 1211 of the nozzle 12 include steam holes 1211 on both sides of the first steam chamber 231, when performing flat ironing operation, in order to prevent the water vapor ejected from the steam holes 1211 on both sides of the nozzle 12 from leaking out through the gap between the nozzle 12 and the ironing base 2, in this embodiment, the upper cover 21 of the ironing base 2 is provided with a plug post 212, and the plug post 212 is correspondingly arranged with the steam holes 1211 on both sides of the first steam chamber 231, and is used to block the steam holes 1211 on both sides of the first steam chamber 231, so that all the water vapor ejected from the nozzle 12 enters the first steam chamber 231 through the steam inlet hole 211 of the upper cover 21, and prevent the steam holes 1211 at both ends of the nozzle 12 from leaking steam.

[0101] As Figure 3 and Figure 4 shown, in order to realize the connection between the nozzle 12 and the ironing base 2, in this embodiment, the surface of the upper cover 21 of the ironing base 2 facing the nozzle 12 may have an installation groove 213, and the installation groove 213 matches the contour of the end of the nozzle 12, and the end of the nozzle 12 is snapped into the installation groove 213.

[0102] By providing the installation groove 213 on the outer surface of the upper cover 21 of the ironing base 2, and the installation groove 213 matches the outer contour of the nozzle end cap 121 of the nozzle 12, when connecting the steam iron body 1 and the ironing base 2, the nozzle end cap 121 is snapped into the installation groove 213 of the upper cover 21 of the ironing base 2.

[0103] In order to firmly connect the garment steamer body 1 and the ironing seat 2, in a possible embodiment, a fixing groove 214 may be further provided on the side of the upper cover 21 of the ironing seat 2 facing the nozzle 12, one end of the fixing groove 214 is connected to the mounting groove 213, and a locking assembly 26 is provided in the fixing groove 214, and the locking assembly 26 is used to connect the garment steamer body 1 to the ironing seat 2.

[0104] Figure 14 A side cross-sectional view of a handheld garment steamer provided by an embodiment of the present invention; Figure 15 for Figure 14 The local schematic diagram of point B in the middle; Figure 16 for Figure 14 The local schematic diagram of the C in the middle; Figure 17 A partial cross-sectional view of a handheld garment steamer provided by an embodiment of the present invention; Figure 18 for Figure 17 Partial schematic diagram at point D in the middle.

[0105] like Figure 4 , Figure 14 and Figure 15 As shown, a fixing groove 214 is provided on the outer surface of the upper cover 21, and one end of the fixing groove 214 is connected to the mounting groove 213, and a locking assembly 26 is provided in the fixing groove 214. The locking assembly 26 can move in the fixing groove 214, and the locking assembly 26 can be moved from the fixing groove 214 to lock with the nozzle end cover 121 in the mounting groove 213, so as to lock the nozzle end cover 121 on the ironing seat 2, thereby realizing a fixed connection between the hanging ironing machine body 1 and the ironing seat 2.

[0106] Specifically, the locking assembly 26 may include a locking member 261 and an elastic member 262, one end of the locking member 261 faces the nozzle 12, one end of the elastic member 262 is connected to the end of the locking member 261 facing away from the nozzle 12, and the other end of the elastic member 262 is connected to the groove wall of the fixing groove 214; a slot 1212 is provided on the nozzle 12 corresponding to the locking member 261, and the locking member 261 can move toward or away from the nozzle 12 so that the end of the locking member 261 is stuck in the slot 1212 or disengaged from the slot 1212.

[0107] like Figure 4 As shown, the locking assembly 26 includes a locking member 261 and an elastic member 262. The locking member 261 is used to engage or disengage with the nozzle end cover 121, and the elastic member 262 is used to push the locking member 261 to move. Figure 15 As shown, one end of the locking member 261 faces the mounting groove 213, that is, the locking member 261 faces the nozzle end cover 121 in the mounting groove 213, one end of the elastic member 262 is connected to the end of the locking member 261 away from the mounting groove 213, and the other end of the elastic member 262 is fixed on the fixing groove 214.

[0108] The deformation state change of the elastic member 262 causes the locking member 261 to move towards or away from the nozzle end cap 121. A clamping groove 1212 is provided at a position on the nozzle end cap 121 corresponding to the end of the locking member 261. When the locking member 261 moves towards the nozzle end cap 121, the end of the locking member 261 can be snapped into the clamping groove 1212 to fix the body 1 of the clothes hanger iron on the ironing base 2; when the locking member 261 moves away from the nozzle end cap 121, the end of the locking member 261 can be disengaged from the clamping groove 1212 to separate the body 1 of the clothes hanger iron and the ironing base 2.

[0109] Taking the elastic member 262 as a spring as an example, the spring is connected between the locking member 261 and the fixing groove 214. The spring can, by virtue of its elastic force, cause the end of the locking member 261 to be snapped into the clamping groove 1212 of the nozzle end cap 121. The user applies a force to the locking component 26 to compress the spring, causing the locking member 261 to retract to a state where it does not extend into the installation groove 213, so as to snap the nozzle end cap 121 into the installation groove 213. Then, after removing the external force on the locking component 26, the elastic force of the compressed spring drives the locking member 261 to move towards the installation groove 213 and snap into the clamping groove 1212 of the nozzle end cap 121. When it is necessary to disassemble the ironing base 2, apply an external force to the locking component 26 again to compress the spring and drive the locking member back into the fixing groove 214.

[0110] As Figure 15 shown, in order to make the assembly of the body 1 of the clothes hanger iron and the ironing base 2 more convenient, in some embodiments, the end of the locking member 261 may have a guiding surface 2611, and the guiding surface 2611 is inclined towards the inside of the clamping groove 1212 from the top to the bottom; wherein, the top of the guiding surface 2611 is located on one side of the locking member 261 facing the notch of the fixing groove 214.

[0111] By providing the guiding surface 2611 at the end of the locking member 261, the guiding surface 2611 is an inclined surface. Specifically, the guiding surface 2611 is inclined towards the inside of the clamping groove 1212 from its top to its bottom, and its top corresponds to the surface of the locking member 261 facing the notch of the fixing groove 214. In this way, during the process of snapping the nozzle end cap 121 into the installation groove 213, the side wall of the nozzle end cap 121 moves into the installation groove 213 along the guiding surface 2611. Through the pressure of the nozzle end cap 121 on the guiding surface 2611, the locking member 261 can be pushed back into the fixing groove 214. Thus, the nozzle end cap 121 can be smoothly snapped into the installation groove 213. When the clamping groove 1212 on the side wall of the nozzle end cap 121 corresponds to the end of the locking member 261, the end of the locking member 261 can be snapped into the clamping groove 1212.

[0112] In addition, as Figure 15As shown, the locking fastener 261 may have a pressing portion 2612 that protrudes outside the upper cover 21. To facilitate the user in applying a force to the locking assembly 26, by providing the pressing portion 2612 on the locking fastener 261, the pressing portion 2612 protrudes outside the upper cover 21. In this way, the user can push the locking fastener 261 back into the fixing groove 214 by pressing the pressing portion 2612, so that the locking fastener 261 is disengaged from the engagement with the card slot 1212 of the nozzle end cover 121, to separate the clothes hanger body 1 and the ironing base 2.

[0113] As Figure 4 and Figure 15 shown, in this embodiment, the locking assembly 26 may further include a locking cover 263. The locking cover 263 covers the notch of the fixing groove 214. The locking cover 263 is provided with a limiting hole 2631. The pressing portion 2612 passes through the limiting hole 2631 and protrudes outside the upper cover 21, and the pressing portion 2612 can move toward or away from the installation groove 213 in the limiting hole 2631.

[0114] To stably arrange the locking fastener 261 and the elastic member 262 in the fixing groove 214, a locking cover 263 is further provided at the notch of the fixing groove 214. The locking fastener 261 and the elastic member 262 are limited in the fixing groove 214 by the locking cover 263, so as to prevent the locking fastener 261 and the elastic member 262 from disengaging from the fixing groove 214 during the movement process, and to ensure the stability of the locking assembly 26.

[0115] Since the locking cover 263 covers the notch of the fixing groove 214, a limiting hole 2631 is further opened in the locking cover 263, so that the pressing portion 2612 on the locking fastener 261 passes through the limiting hole 2631 and protrudes outside the upper cover 21. Moreover, the pressing portion 2612 can move along the moving direction of the locking fastener 261 in the limiting hole 2631, that is, the pressing member can move toward or away from the installation groove 213 in the limiting hole 2631.

[0116] In addition, as Figure 15 shown, to further improve the connection stability between the locking fastener 261 and the elastic member 262, one end of the locking fastener 261 connected to the elastic member 262 may have a limiting protrusion 2613, and the end of the elastic member 262 is clamped on the limiting protrusion 2613.

[0117] By providing the limiting protrusion 2613 at one end of the locking fastener 261 connected to the elastic member 262, taking the elastic member 262 as a spring as an example, the end of the spring can be sleeved on the limiting protrusion 2613. In this way, it can be ensured that the spring is firmly connected to the locking fastener 261, thereby improving the stability of the locking assembly 26.

[0118] As Figure 7 and Figure 16As shown, in order to further firmly connect the ironing seat 2 to the hanging iron body 1, in a possible embodiment, the installation groove 213 of the upper cover 21 of the ironing seat 2 may have a positioning groove 215 on the side opposite to the fixing groove 214, and the end of the nozzle 12 may be provided with a positioning boss 1213 corresponding to the positioning groove 215, and the positioning boss 1213 is inserted into the positioning groove 215.

[0119] In this embodiment, on the basis that the ironing seat 2 is fixedly connected with the slot 1212 of the nozzle end cover 121 through the lock assembly 26, in order to further improve the firmness of the connection between the ironing seat 2 and the garment steamer body 1, a positioning groove 215 is further provided on the side of the mounting groove 213 of the upper cover 21 of the ironing seat 2 opposite to the fixing groove 214, and a positioning boss 1213 is provided at a portion of the nozzle end cover 121 corresponding to the positioning groove 215, and the positioning boss 1213 matches the positioning groove 215. When the ironing seat 2 is connected with the nozzle 12 of the garment steamer body 1, the positioning boss 1213 of the nozzle end cover 121 is inserted into the positioning groove 215 of the mounting groove 213 of the ironing seat 2, which can not only realize the positioning of the nozzle 12, but also both sides of the nozzle end cover 121 are fixedly connected with the ironing seat 2, which can make the connection between the two more firm.

[0120] like Figure 4 and Figure 17 , Figure 18 As shown, in order to realize secondary heating of the water vapor entering the heating chamber 23 by the heating part 25 of the ironing seat 2, in some embodiments, a conductive needle 2511 can be connected to the heating tube 251 of the heating part 25 of the ironing seat 2, and the conductive needle 2511 extends toward the upper cover 21. A through hole 243 is provided at a position corresponding to the conductive needle 2511 on the heat conducting plate 24, and the upper cover 21 is provided with an isolation column 216 extending into the through hole 243. The isolation column 216 has an outlet hole 2161, and the conductive needle 2511 passes through the outlet hole 2161 to be electrically connected to the garment steamer body 1.

[0121] By connecting a conductive needle 2511 to the heating tube 251, taking the heating tube 251 as a "U-shaped" heating tube 251 as an example, the conductive needles 2511 can be respectively connected to the two ends of the "U-shaped" heating tube 251, and electrically connected to the garment steamer body 1 through the conductive needles 2511. In this way, the current of the garment steamer body 1 can be transmitted to the heating tube 251 through the conductive needles 2511, so as to control the heating tube 251 to heat up and perform secondary heating of the water vapor.

[0122] Specifically, the conductive needle 2511 extends toward the upper cover 21 and passes through the heat conducting plate 24 and the upper cover 21 in sequence to be electrically connected to the garment steamer body 1. By setting a through hole 243 on the heat conducting plate 24, setting an isolation column 216 on the upper cover 21 to extend into the through hole 243 of the heat conducting plate 24, and setting an exit hole 2161 inside the isolation column 216, the conductive needle 2511 passes through the exit hole 2161 to extend out of the upper cover 21 and be electrically connected to the garment steamer body 1.

[0123] In order to prevent steam from leaking outward from the gap between the conductive pin 2511 and the through hole 2161 of the upper cover 21, in some embodiments, the gap between the conductive pin 2511 and the through hole 2161 may be filled with sealant. By filling the sealant into the through hole 2161 of the isolation column 216 of the upper cover 21, the sealant seals the gap between the conductive pin 2511 and the through hole 2161, thereby preventing water vapor from leaking outward from the through hole 2161.

[0124] Regarding the electrical connection between the conductive needle 2511 of the heating tube 251 and the garment steamer body 1, in a specific embodiment, a conductive spring 1214 may be provided on the inner wall of the nozzle end cover 121, and the conductive needle 2511 extends into the nozzle end cover 121 and contacts the conductive spring 1214, so as to be electrically connected to the garment steamer body 1 through the conductive spring 1214.

[0125] like Figure 5 , Figure 6 and Figure 18 As shown, a conductive spring 1214 is provided on the inner wall of the nozzle end cover 121 at a position corresponding to the conductive needle 2511, and the conductive needle 2511 extends into the nozzle end cover 121 and contacts the conductive spring 1214, and the conductive spring 1214 is electrically connected to the garment steamer body 1, thereby realizing the electrical connection between the heating tube 251 in the ironing seat 2 and the garment steamer body 1.

[0126] The conductive spring piece 1214 in the nozzle end cover 121 is electrically connected to the charging part 13 connected to the other end of the handle 11 , and the charging part 13 is electrically connected to the charging seat 14 , thereby realizing the electrical connection between the conductive spring piece 1214 and the charging seat 14 .

[0127] In this embodiment, the heating tube 251 of the ironing seat 2 is electrically connected to the garment steamer body 1 by means of the conductive pin 2511 and the conductive spring sheet 1214. The electrical connection between the heating tube 251 and the garment steamer body 1 is more convenient, and the space occupied by the conductive pin 2511 and the conductive spring sheet 1214 can be saved. It should be understood that the electrical connection between the heating tube 251 and the garment steamer body 1 can also be achieved by other means such as a coupler, and this embodiment does not limit this.

[0128] The handheld steam iron provided in this embodiment can achieve the flat ironing function of the handheld steam iron by setting an ironing base that is detachably connected to the steam iron body. Among them, the ironing base is connected to the end of the nozzle of the steam iron body. By setting a heating cavity in the ironing base, the water vapor generated by the nozzle enters the heating cavity through the steam inlet hole of the ironing base. The heating cavity can reheat the water vapor, and by arranging a plurality of steam outlet holes at intervals on the ironing surface of the ironing base, the reheated water vapor is sprayed outwards through these plurality of steam outlet holes. In this way, the ironing efficiency during the flat ironing operation of the handheld steam iron can be improved, the ironing effect can be enhanced, and thus the user experience can be improved.

[0129] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
