Technical Field
[0001] This utility model belongs to the field of iron technology, specifically, it relates to an iron soleplate and an iron. Background Technology
[0002] An iron, a common household appliance, primarily functions to remove wrinkles from clothing using high temperatures, making garments smoother and more attractive. During the ironing process, the soleplate is the crucial part that directly contacts the clothing, and its design directly affects the iron's performance and the protection it provides to the garments.
[0003] Traditional iron soleplates are typically made of rigid metal. Users usually need to place a pressing cloth on top of the clothes when ironing. This cloth effectively disperses heat, preventing direct contact between the clothes and the iron soleplate, which can cause burns, dents, or damage, especially to heat-sensitive fabrics like wool and silk. However, using a pressing cloth can be inconvenient and makes it difficult to iron clothes flat. Utility Model Content
[0004] The purpose of this invention is to provide an iron soleplate with a cloth pad and an iron, which solves the problem that traditional irons require a separate lining cloth when ironing clothes, which is inconvenient.
[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0006] According to a first aspect of the present invention, an iron soleplate is provided, comprising:
[0007] The first pressure frame forms a mounting portion for connection with the bottom edge of the iron body, and a first snap-fit portion;
[0008] The second pressure frame forms a second snap-fit portion, which snaps into the first snap-fit portion;
[0009] The lining includes a piece of fabric for contact with clothing, the edges of which are held between the first and second pressure frames.
[0010] In some embodiments of this utility model, the lining further includes a rigid frame, which is fixedly connected to the edge of the fabric and supports the fabric, and is sandwiched between the first pressure frame and the second pressure frame.

[0042] This utility model provides an iron soleplate, which is used to be installed on the bottom of the iron body. Figures 1 to 6 This illustration shows an embodiment of an iron soleplate provided by the present invention.
[0043] In this embodiment, the iron soleplate includes a first pressure frame 10, a second pressure frame 20, and an inner liner 30. The first pressure frame 10 forms a mounting portion and a first snap-fit portion, the mounting portion being used to connect with the bottom edge of the iron body 40. The second pressure frame 20 forms a second snap-fit portion, the second snap-fit portion engaging with the first snap-fit portion, thereby connecting the first pressure frame 10 and the second pressure frame 20. The inner liner 30 includes a fabric piece 31, the fabric piece 31 being used to contact clothing, the edge of the fabric piece 31 being held between the first pressure frame 10 and the second pressure frame 20, the first pressure frame 10 and the second pressure frame 20 fixing the inner liner 30, enabling the fabric piece 31 to remain flat, thereby ironing the clothing flat.
[0044] During use, the bottom of the iron body 40 is separated from the clothes being ironed by a cloth 31. The cloth 31 contacts the clothes, preventing the iron body 40 from burning them. The cloth 31 is softer than the metal soleplate of a traditional iron, reducing the problem of indentations on the clothes. The cloth 31 can move with the iron body 40, making it more convenient to use.
[0045] The first pressure frame 10 and the second pressure frame 20 are connected by the first snap-fit part and the second snap-fit part, making them easy to install and remove. The fabric piece 31 of the inner lining 30 is easily worn out after long-term use. The first pressure frame 10 and the second pressure frame 20 can be removed to replace the new inner lining 30, and the new inner lining 30 can be installed between the first pressure frame 10 and the second pressure frame 20.
[0046] The mounting part of the first pressure frame 10 can be detachably connected to the bottom of the iron body 40, and the iron soleplate can be completely removed from the iron body 40 for replacement.
[0047] The fabric piece 31 can be made of cotton, linen, high-temperature resistant polyester, or other fabrics. The first pressure frame 10 and the second pressure frame 20 can be made of rigid materials such as metal or plastic. The first pressure frame 10, the second pressure frame 20, and the inner lining 30 also have the advantages of simple structure and low manufacturing cost.
[0048] In this embodiment, as Figure 1 and Figure 2 As shown, the first pressure frame 10 and the second pressure frame 20 are fitted together vertically. The first snap-fit part is located at the bottom of the first pressure frame 10, and the second snap-fit part is located at the top of the second pressure frame 20. The first pressure frame 10 and the second pressure frame 20 are snapped together vertically, and the inner lining 30 is fixed between the two.
[0049] In other embodiments, the first pressing frame 10 and the second pressing frame 20 may also be mated internally and externally. For example, the first pressing frame 10 may be mated on the outside of the second pressing frame 20, or the first pressing frame 10 may be mated on the inside of the second pressing frame 20.
[0050] In some implementations, such as Figure 2As shown, the lining 30 also includes a rigid frame 32, which is fixedly connected to the edge of the fabric piece 31 and supports the fabric piece 31. The rigid frame 32 is sandwiched between the first pressing frame 10 and the second pressing frame 20. The fabric piece 31 is made of soft material, and the rigid frame 32 supports the fabric piece 31, which can keep the fabric piece 31 flat, thereby making it easier to iron the clothes.
[0051] The rigid frame 32 can be made of rigid plastic or metal. The fabric piece 31 can be fixedly connected to the rigid frame 32 by means of bonding, pressing, etc. The first pressure frame 10 and the second pressure frame 20 fix the inner lining 30 by clamping the rigid frame 32, which can make it more stable. The rigid frame 32 is not easy to deform and is not easy to detach from the first pressure frame 10 and the second pressure frame 20, so the inner lining 30 is not easy to fall off.
[0052] like Figure 6 In one specific embodiment shown, the rigid frame 32 has an annular structure with a recessed fixing groove formed on its inner side, which surrounds the inner side of the rigid frame 32. The edge of the fabric piece 31 extends into the fixing groove and can be further fixed by adhesive to prevent the fabric piece 31 from falling off.
[0053] The first snap-fit portion of the first pressure frame 10 and the second snap-fit portion of the second pressure frame 20 can be a snap-fit structure with a concave-convex fit, and can be a transition fit or an interference fit, enabling installation and disassembly.
[0054] Specifically, the first snap-fit part of the first pressure frame 10 is an annular first snap-fit groove 11, and the second snap-fit part of the second pressure frame 20 is an annular second snap-fit strip 21. The second snap-fit strip 21 can be embedded in the first snap-fit groove 11 to achieve snap-fit fixation.
[0055] Furthermore, a second positioning protrusion 22 is provided on one side of the second locking strip 21, and a first positioning groove 12 corresponding to the second positioning protrusion 22 is provided on the inner wall of the first locking groove 11. The second positioning protrusion 22 cooperates in the first positioning groove 12 to strengthen the connection between the second locking strip 21 and the first locking groove 11, and prevent the second locking strip 21 from accidentally dislodging from the first locking groove 11 and causing the inner liner 30 to fall off.
[0056] The second positioning protrusion 22 extends along the annular second retaining strip 21, forming an annular structure. The first positioning groove 12 extends along the annular first retaining groove 11, forming an annular structure. The shape of the first positioning groove 12 is adapted to the shape of the second positioning protrusion 22.
[0057] The surface of the second positioning protrusion 22 can be set as an arc surface to facilitate entering the first slot 11 and engaging with the first positioning groove 12. The first positioning groove 12 can be set as an arc-shaped structure adapted to the second positioning protrusion 22.
[0058] In some implementations, such as Figure 5 and Figure 6 As shown, the bottom surface of the first pressing frame 10 forms a first pressing surface 13 near the inner side, and the top surface of the second pressing frame 20 forms a second pressing surface 23 near the inner side. The rigid frame 32 of the inner liner 30 is sandwiched between the first pressing surface 13 and the second pressing surface 23. The first pressing surface 13 and the second pressing surface 23 press against the upper and lower sides of the rigid frame 32 respectively, which can strengthen the fixing effect and make the inner liner 30 securely installed.
[0059] In some implementations, such as Figure 5 and Figure 6 As shown, the bottom surface of the first pressure frame 10 forms a first mating surface 14 near the outer side, and the top surface of the second pressure frame 20 forms a second mating surface 24 near the outer side. The first mating surface 14 and the second mating surface 24 abut against each other, which can improve the mating stability of the first pressure frame 10 and the second pressure frame 20.
[0060] Specifically, such as Figure 6 As shown, the first slot 11 at the bottom of the first pressure frame 10 is located between the first pressing surface 13 and the first mating surface 14. The second strip 21 at the bottom of the second pressure frame 20 is located between the second pressing surface 23 and the second mating surface 24, and the second pressing surface 23 and the side of the second strip 21 form a concave annular groove structure.
[0061] When the first pressing frame 10 and the second pressing frame 20 are engaged, there is a gap between the first pressing surface 13 and the second pressing surface 23. The sides of the first pressing surface 13, the second pressing surface 23 and the second locking strip 21 form a U-shaped groove for installing the rigid frame 32.
[0062] Reference Figure 6 From a certain perspective, the first pressing surface 13 can be higher than or flush with the first mating surface 14, and the second pressing surface 23 can be lower than or flush with the second mating surface 24. It must be ensured that when the first pressing frame 10 and the second pressing frame 20 are engaged vertically, there is a gap between the first pressing surface 13 and the second pressing surface 23, and that the first mating surface 14 and the second mating surface 24 are in contact.
[0063] During installation, the inner lining 30 can be installed on the second pressure frame 20 first, so that the rigid frame 32 fits into the annular groove structure formed by the second pressing surface 23 and the side of the second clip 21 for installation and positioning. Then, the first pressure frame 10 and the second pressure frame 20 are fastened together, so that the second clip 21 is inserted into the first clip groove 11.
[0064] In some implementations, such as Figure 5As shown, the first pressure frame 10 is detachably connected to the bottom of the iron body 40. The mounting part is an inner corner groove 15 surrounding the inner side of the first pressure frame 10. The inner corner groove 15 extends from the inner side of the first pressure frame 10 to the bottom. The bottom edge of the iron body 40 is provided with a flange 41, and the inner corner groove 15 is used to engage with the flange 41. The liner 30 fits into the bottom of the iron body 40. The inner corner groove 15 of the first pressure frame 10 engages with the flange 41 of the iron body 40, thereby realizing the connection between the iron soleplate and the iron body 40.
[0065] In other embodiments, the mounting portion of the first pressure frame 10 can be configured as a U-shaped groove, a locking block, or other snap-fit structure. The mounting portion can also be configured as a through-hole structure, and fixedly connected to the iron body 40 by fasteners such as mounting screws and pins. Those skilled in the art can also configure the mounting portion as other conventional connection structures according to the specific structure of the iron body 40.
[0066] In some implementations, such as Figure 2 As shown, for ease of installation and disassembly, the first pressure frame 10 may be provided with a handle 16 for easy assembly and disassembly. The handle 16 protrudes outward from the first pressure frame 10.
[0067] In detail, the first pressure frame 10 is snapped onto the iron body 40 via the mounting part. During disassembly, the first pressure frame 10 can be deformed to a certain extent by turning the handle part 16, thereby detaching it from the iron body 40, and the iron soleplate can be removed as a whole. The handle part 16 can fix the first pressure frame 10, thus facilitating the disassembly of the first pressure frame 10 and the second pressure frame 20.
[0068] The handle 16 can be designed as a hanging loop to facilitate the storage of the iron soleplate.
[0069] In some embodiments, the soleplate can be applied to a steam iron, with a steam vent formed at the bottom of the iron body 40 for ejecting steam. The fabric 31 of the soleplate is made of a more breathable material so that steam can pass through the fabric 31 more easily and the steam distribution is more even, resulting in better ironing of clothes.
[0070] Furthermore, the fabric piece 31 can be designed as a more breathable mesh structure, or small holes for steam to pass through can be evenly arranged on the fabric piece 31, making it easier for steam to pass through the fabric piece 31 and reach the clothes, thereby improving the ironing effect.
[0071] Figure 7 and Figure 8 This illustration shows a second embodiment of an iron soleplate provided by the present invention.
[0072] In this embodiment, the iron soleplate includes a first pressure frame 10, a second pressure frame 20, and an inner liner 30. The first pressure frame 10 forms a mounting portion and a first snap-fit portion, the mounting portion being used to connect with the bottom edge of the iron body 40. The inner liner 30 includes a fabric piece 31 for contacting clothing, the edge of the fabric piece 31 being sandwiched between the first pressure frame 10 and the second pressure frame 20, the first pressure frame 10 and the second pressure frame 20 fixing the inner liner 30. The second pressure frame 20 forms a second snap-fit portion, the second snap-fit portion engaging with the first snap-fit portion, thereby connecting the first pressure frame 10 and the second pressure frame 20.
[0073] Specifically, the first snap-fit part is located at the bottom of the first pressure frame 10, and the second snap-fit part is located at the top of the second pressure frame 20. The first pressure frame 10 and the second pressure frame 20 are interlocked, and the inner liner 30 is fixed between them. The first snap-fit part is a first snap-fit strip 17, and the second snap-fit part is an annular second snap-fit groove 25. The first snap-fit strip 17 can be inserted into the second snap-fit groove 25 to connect the first pressure frame 10 and the second pressure frame 20, and facilitates installation and disassembly. After a period of use, the first pressure frame 10 and the second pressure frame 20 can be disassembled and a new inner liner 30 can be replaced. The mounting part of the first pressure frame 10 can be detachably connected to the bottom of the iron body 40, and the soleplate can be completely removed from the iron body 40 for replacement.
[0074] The lining 30 also includes a rigid frame 32, which is fixedly connected to the edge of the fabric piece 31 and supports the fabric piece 31. The rigid frame 32 is sandwiched between the first pressing frame 10 and the second pressing frame 20. The rigid frame 32 supports the fabric piece 31, which can keep the fabric piece 31 flat, thereby making it easier to iron the clothes.
[0075] Furthermore, a first positioning protrusion 18 is provided on one side of the first card strip 17, and a second positioning groove 26 corresponding to the first positioning protrusion 18 is provided on the inner wall of the second card groove 25. The first positioning protrusion 18 cooperates in the second positioning groove 26 to strengthen the connection between the first card strip 17 and the second card groove 25, and prevent the first card strip 17 from accidentally detaching from the second card groove 25, which would cause the inner liner 30 to fall off.
[0076] Specifically, the first positioning protrusion 18 extends along the annular first retaining strip 17, forming an annular structure. The second positioning groove 26 extends along the annular second retaining groove 25, forming an annular structure. The surface of the first positioning protrusion 18 can be set as an arc surface to facilitate entering the second retaining groove 25 and engaging with the second positioning groove 26. The second positioning groove 26 can be set as an arc-shaped structure adapted to the first positioning protrusion 18.
[0077] In some embodiments, the bottom surface of the first pressing frame 10 forms a first pressing surface 13 near the inner side and a first mating surface 14 near the outer side, and the first locking strip 17 is located between the first pressing surface 13 and the first mating surface 14. The top surface of the second pressing frame 20 forms a second pressing surface 23 near the inner side and a second mating surface 24 near the outer side, and the second locking groove 25 is located between the second pressing surface 23 and the second mating surface 24.
[0078] The first pressing surface 13 and the second pressing surface 23 press against the upper and lower sides of the rigid frame 32 respectively, so that the inner liner 30 is securely installed. The first mating surface 14 abuts against the second mating surface 24, which can improve the mating stability of the first pressing frame 10 and the second pressing frame 20.
[0079] The first pressing surface 13 of the first pressing frame 10 and the side of the first locking strip 17 form an annular groove structure. During installation, the inner liner 30 can be installed on the first pressing frame 10 first, so that the rigid frame 32 fits in the annular groove structure formed by the first pressing surface 13 and the side of the first locking strip 17 for installation and positioning.
