Description

Technical Field

[0001] This utility model pertains to clothing ironing appliances, specifically relating to a steam iron that makes it easy to keep the air intake vent clean. Background Technology

[0002] When using a garment steamer, the released steam can blow clothes away from the work surface, hindering the steam and the work surface from effectively ironing the clothes. This defect can be overcome by using a suction fan and suction holes distributed across the work surface to draw the clothes towards it. However, in existing handheld garment steamers, the suction holes are machined into the work surface, which has a certain thickness. This results in a relatively large depth of the suction holes (corresponding to the thickness of the work surface), making them prone to dust accumulation. Dust deposits inside the suction holes are difficult to clean and also reduce the airflow diameter, leading to increased suction noise and reduced suction power.

[0003] Moreover, the existing air intake is located on the front surface of the work surface, and this front surface is usually flat. If the work surface is tilted relative to the clothes during ironing, the clothes are easy to fall off the work surface and leak air, making it difficult to adhere the clothes to the work surface to cover the steam holes. Utility Model Content

[0004] This invention addresses the shortcomings of existing handheld garment steamers where the suction holes are machined on the working surface, resulting in a larger depth of the suction holes, which easily accumulates dust. Dust deposits inside the suction holes are not only difficult to clean, but also reduce the flow diameter of the suction holes, leading to increased suction noise and reduced suction power. This invention provides a steam iron that makes it easy to keep the suction holes clean. Furthermore, it overcomes the shortcomings of the suction holes being distributed on the front surface of the working surface, which causes the clothes to easily detach from the working surface and leak air when the working surface is tilted relative to the clothes during ironing, and makes it difficult to adhere the clothes to the working surface to cover the steam holes.

[0005] To achieve the above objectives, the present invention provides a steam iron that easily keeps the air intake vent clean, comprising: The head housing is equipped with ventilation holes; A vaporization device used to vaporize water into steam; The working surface is assembled at the front end of the head shell. The working surface is equipped with steam holes and suction holes. The steam holes are used to release steam from the vaporization device, and the suction holes are used to adsorb clothes onto the working surface by suction. A suction fan is used to draw air in through the suction port and exhaust air through the exhaust port. The working surface is equipped with an air intake, and a filter screen corresponding to the air intake is installed on the back side of the working surface. The thickness of the filter screen is less than the thickness of the working surface. The front surface of the filter screen is smoothly transitioned to the front surface of the working surface, and the air intake hole is the mesh of the filter screen.

[0006] This steam iron, because the front surface of the filter screen and the front surface of the working surface are smoothly transitioned, will not form a dead corner for dust accumulation at the junction of the filter screen and the working surface, thus keeping the front surface of the filter screen and the front surface of the working surface clean.

[0007] This steam iron features a suction port that is part of a filter mesh. Since the filter mesh is significantly thinner than the working surface, the mesh depth is shallow, making it less prone to dust accumulation. This allows the suction port to remain clear and clean. Even if dust is present, the brush bristles can easily reach into the mesh to remove it. The high mesh density also minimizes airflow resistance, helping to maintain stable suction and reduce noise during operation.

[0008] Preferably, the filter screen has a protrusion that is embedded in the air intake, allowing the front surface of the filter screen to smoothly transition with the front edge of the air intake hole. This eliminates dust accumulation dead zones caused by the large thickness of the working surface, and also positions the filter screen relative to the working surface by constraining the protrusion through the air intake, preventing the filter screen from shaking.

[0009] In one embodiment, the filter screen is a woven wire mesh.

[0010] In another embodiment, the filter screen is formed by distributing mesh holes on a sheet.

[0011] Preferably, the filter screen is held in place on the back side of the working surface by a support frame. This prevents deformation due to insufficient filter screen rigidity, keeps the filter screen in its assembled position, and achieves the required suction effect.

[0012] Preferably, the bracket has a contour that matches the filter and maintains a channel at the corresponding air intake position. This ensures unobstructed air intake and avoids airflow obstruction that could increase noise.

[0013] In one embodiment, the front surface of the working surface is a plane.

[0014] In another embodiment, the front surface of the working surface has a first recess, and the air intake is located in the first recess. During suction, the first recess has a large capacity and maintains negative pressure. If the working surface is tilted relative to the clothes, the negative pressure of the first recess can generate a continuous suction force. This suction force can more easily attract the clothes to the working surface, ensuring that the clothes do not fall off the working surface and that the clothes are attracted to the working surface to cover the steam holes. When the clothes cover the steam holes, the steam can be fully applied to the clothes and will not escape from the gap between the clothes and the working surface, resulting in better steam ironing effect and higher efficiency.

[0015] In one embodiment, the first recess is located below the steam hole. When ironing hanging clothes, the suction of the steam hole adsorbs the clothes onto the work surface, and moves the work surface downwards along with the clothes, achieving ironing while simultaneously pulling the clothes downwards, which helps to improve ironing efficiency and ironing effect.

[0016] In another embodiment, the first recess surrounds the steam vent. When clothing is adsorbed onto the work surface, in addition to ironing hanging clothing by moving the work surface downward relative to the clothing, ironing can also be performed by moving the work surface in various directions to iron flat clothing, increasing the flexibility of ironing.

[0017] Preferably, the first recess is defined inside the flange at the edge of the working surface. This structure defines a large first recess, and regardless of whether the suction holes are distributed only in a part of the first recess or in the entire area of ​​the first recess, continuous suction can be generated through the connectivity of the first recess, thereby adsorbing clothing onto the working surface to cover the steam holes.

[0018] Preferably, the working surface has a second recess, and steam holes are distributed in the second recess. When clothing covers the steam holes, the second recess can store steam, thereby increasing the area of ​​steam contact with the clothing. This means that clothing corresponding to the second recess can be ironed with steam simultaneously. When the working surface is moved relative to the clothing, clothing of a larger width (corresponding to the area of ​​the second recess) can be ironed. By repeatedly moving the working surface, the entire width of the clothing can be ironed. If there is no second recess, and the steam holes directly contact the clothing, then because the diameter of the steam holes is small, when the working surface is moved relative to the clothing, only clothing of a very small width (corresponding to the diameter of the steam holes) can be ironed. Clothing between adjacent steam holes cannot come into contact with the clothing, and even with repeated movement of the working surface, it is difficult to iron the entire width of the clothing.

[0019] This invention features an air intake on the working surface, with a corresponding filter screen mounted on the back side of the working surface. The filter screen is thinner than the working surface, and its front surface smoothly transitions to the front surface of the working surface. The air intake holes are the mesh openings of the filter screen. No dust accumulation dead zones are formed at the junction of the filter screen and the working surface, thus keeping both the front surfaces of the filter screen and the working surface clean. Furthermore, the shallow mesh depth of the air intake holes makes them less prone to dust accumulation, ensuring they remain clear and clean. Even if dust is present, the brush bristles can easily reach into the mesh openings to remove it. The high mesh density also reduces airflow resistance, facilitating stable suction and reducing noise during suction.

[0020] This invention distributes the suction holes in a first recess on the working surface. During suction, the first recess has a large capacity and maintains negative pressure. If the working surface is tilted relative to the clothes, the negative pressure in the first recess generates a continuous suction force. This suction force makes it easier to adhere the clothes to the working surface, ensuring that the clothes do not detach and are adhered to the working surface to cover the steam holes. When the clothes cover the steam holes, the steam can be fully applied to the clothes and will not escape from the gap between the clothes and the working surface, resulting in better steam ironing effect and higher efficiency.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0024] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0025] Example 1 Figure 1-3 A steam iron that is easy to keep clean at the suction vent is shown. The steam iron includes a head housing 100, a vaporizing device 200, a working surface 300, and a suction fan 400.

[0026] The head housing 100 is equipped with a vent 101. For ease of assembly, the head housing is an assembly structure.

[0027] The vaporization device 200 is used to vaporize water into steam.

[0028] The working surface 300 is mounted on the front end of the head housing 100 and is used to face or even contact the clothing during ironing. The ironing surface faces forward. The working surface is provided with steam holes 301 and suction holes 302. The steam holes 301 are used to release steam from the vaporization device, and the suction holes 302 are used to suction the clothing to the working surface.

[0029] The suction fan 400 is located inside the head housing 100. When the suction fan 400 is working, it draws air from the suction hole 302 of the working surface 300 and exhausts air from the exhaust hole 101 of the head housing 100.

[0030] The working surface 300 is provided with an air intake 305. A filter screen 500 corresponding to the air intake is installed on the back side of the working surface. The thickness of the filter screen is less than the thickness of the working surface. The front surface of the filter screen 500 is smoothly transitioned to the front surface of the working surface 300. The air intake hole 302 is the mesh of the filter screen 500.

[0031] This steam iron, because the front surface of the filter screen and the front surface of the working surface are smoothly transitioned, will not form a dead corner for dust accumulation at the junction of the filter screen and the working surface, thus keeping the front surface of the filter screen and the front surface of the working surface clean.

[0032] This steam iron features a suction port that is part of a filter mesh. Since the filter mesh is significantly thinner than the working surface, the mesh depth is shallow, making it less prone to dust accumulation. This allows the suction port to remain clear and clean. Even if dust is present, the brush bristles can easily reach into the mesh to remove it. The high mesh density allows for a larger overall diameter of the suction port within the limited area of ​​the working surface, resulting in less airflow resistance, maintaining stable suction power, and reducing noise during operation.

[0033] In this embodiment, the filter 500 has multiple protrusions 502, which are respectively embedded in the corresponding air inlets 305 to make the front surface of the filter screen smoothly transition with the front edge of the air inlet 302. This can eliminate the dust accumulation dead corners caused by the large thickness of the working surface, and also position the filter screen relative to the working surface by constraining the protrusions through the air inlets, thus preventing the filter screen from shaking.

[0034] In this embodiment, the filter screen 500 is a woven wire mesh, such as a filter screen woven from steel wire.

[0035] In this embodiment, the filter 500 is held in place on the back side of the working surface 300 by the support frame 501. This prevents deformation caused by insufficient rigidity of the filter and keeps it in the assembled position to achieve the desired suction effect.

[0036] In this embodiment, the bracket 501 has a contour that matches the filter 500 and maintains a channel 503 at the position corresponding to the air intake 305. This ensures unobstructed air intake and avoids airflow obstruction that could increase noise.

[0037] In this embodiment, the front surface of the working surface 300 is flat. The front surface of the filter screen 500 is flush with the front surface of the working surface to maintain smoothness and avoid dust accumulation dead corners.

[0038] In this embodiment, a second recess 306 is provided on the working surface 300, and steam holes 301 are distributed in the second recess 306. When clothing covers the steam holes, the second recess can store steam, thereby increasing the area of ​​steam contact with the clothing. This means that clothing corresponding to the second recess can be ironed with steam simultaneously. When the working surface is moved relative to the clothing, clothing of a larger width (corresponding to the area of ​​the second recess) can be ironed. By repeatedly moving the working surface, the entire width of the clothing can be ironed. If there is no second recess, the steam holes directly contact the clothing. Due to the small diameter of the steam holes, when the working surface is moved relative to the clothing, only clothing of a very small width (corresponding to the diameter of the steam holes) can be ironed. Clothing between adjacent steam holes cannot come into contact with the clothing. Even with repeated movement of the working surface, it is difficult to iron the entire width of the clothing.

[0039] like Figure 1As shown, a handle 600 for gripping extends downward from the head housing 100. The lower end of the handle 600 is connected to a seat 700, through which the steam iron can be placed on the platform. In other embodiments, the seat may be omitted, such as in garment steamers, where a semi-circular opening is typically provided for the steam iron, allowing the handle to be placed within the semi-circular space.

[0040] Example 2 Figure 4-6 Another steam iron that easily keeps the air intake vents clean is shown. The only difference between this embodiment and Embodiment 1 is that the front surface of the working surface 300 has a first recess 303, and the air intake 305 is located in the first recess 303. The filter 500 has a protrusion 502 located within the air intake 305, and the front end face of the protrusion 502 is flush with the bottom surface of the first recess 303, allowing a smooth transition between the front end face of the protrusion and the bottom surface of the first recess. This results in the air intake vents 302 being distributed in the first recess 303. Furthermore, in this embodiment, the filter 500 is formed by distributing mesh holes on a sheet material. The sheet material is typically a thin metal plate, preferably 0.25mm-0.5mm thick.

[0041] During suction, the first concave section has a large capacity and maintains negative pressure. If the working surface is tilted relative to the clothes, the negative pressure of the first concave section generates a continuous suction force. This suction force makes it easier to adhere the clothes to the working surface, ensuring that the clothes do not detach and are adhered to the working surface to cover the steam holes. When the clothes cover the steam holes, the steam can be fully applied to the clothes and will not escape from the gap between the clothes and the working surface, resulting in better steam ironing effect and higher efficiency.

[0042] In this embodiment, the first recess 303 is located below the steam hole 301. When ironing hanging clothes, the suction hole adsorbs the clothes onto the working surface, and the working surface moves downward along with the clothes, achieving ironing while also pulling the clothes downward, which helps to improve ironing efficiency and ironing effect.

[0043] The other structures of the steam iron in this embodiment are the same as those in Embodiment 1, and will not be described in detail here.

[0044] Example 3 Figure 7-9 A third type of steam iron that easily keeps the air intake vent clean is shown. The steam iron in this embodiment differs from that in Embodiment 2 only in the first recess 303 and the filter 500. In this embodiment, the first recess 303 surrounds the steam vent 301. When clothing is attached to the work surface, ironing can be performed not only by moving the work surface downwards relative to the clothing when it is hanging, but also by moving the work surface in various directions when it is laid flat, increasing the flexibility of ironing.

[0045] Furthermore, the first recess 303 is defined inside the flange 304 at the edge of the working surface 300. This structure defines a large area of ​​the first recess 303, and whether the suction holes 302 are only distributed in a part of the first recess 303 or distributed in the entire area of ​​the first recess 303, a continuous suction force can be generated by the communication effect of the first recess, thereby adsorbing the clothes onto the working surface to cover the steam holes.

[0046] In this embodiment, the filter screen 500 is a woven wire mesh, such as a filter screen woven from steel wire.

[0047] The other structures of the steam iron in this embodiment are the same as those in Embodiment 2, and will not be described in detail.
