Description

Technical Field

[0001] This application relates to cleaning equipment technology, and more particularly to a suction head and an ironing machine. Background Technology

[0002] With the improvement of living standards, ironing machines, as a household appliance that can iron clothes, have become increasingly popular. Ironing machines usually have an ironing panel with a steam outlet. Users can hold the ironing machine and make the ironing panel contact the clothes to be ironed. The high-temperature steam sprayed from the steam outlet is used to iron the clothes, which loosens the clothing fibers and reduces wrinkles.

[0003] In related technologies, ironing machines are usually equipped with suction components. The ironing panel has an air intake. The suction component generates suction force, which adsorbs the clothes onto the ironing panel through the air intake to ensure stable contact between the ironing panel and the clothes and to ensure the ironing effect.

[0004] However, when ironing clothes, dust, hair and fabric debris on the clothes will inevitably be sucked into the suction unit by the suction, causing blockage or even damage to the suction unit. Utility Model Content

[0005] In view of this, this application provides a suction head and an ironing machine that can prevent dust, hair and fabric debris on clothing from being sucked into the suction component, thus solving the problem of clogging or even damage to the suction component.

[0006] To achieve the above objectives, this application provides a steaming head and an ironing machine, which adopts the following technical solution:

[0007] In a first aspect, this application provides a hot water suction head, comprising:

[0008] case;

[0009] A suction assembly is disposed within the housing, and the suction assembly has an air inlet channel;

[0010] A filter assembly includes a support, a protrusion, and a filter element; the support is inserted into the housing and is located outside the air inlet channel;

[0011] The protrusion is provided to protrude toward the air inlet channel relative to the support portion, and at least a portion of the protrusion is located within the air inlet channel; the protrusion is provided with a mounting hole, and the filter element is disposed within the mounting hole.

[0012] In this way, by placing the protruding part of the filter component inside the air inlet channel, the intake airflow must first pass through the filter element, effectively intercepting impurities such as dust, hair, and fabric debris from clothing, preventing them from entering the suction component and thus avoiding blockage or damage. Furthermore, this design reduces the impact on airflow resistance while ensuring filtration effectiveness, minimizing noise and vibration caused by airflow turbulence, and improving the user experience.

[0013] In one possible implementation, the suction head provided in this application has a housing with a insertion groove, the insertion groove being connected to the air inlet channel, and the support portion being inserted into the insertion groove.

[0014] In this way, by setting a plug-in groove on the housing that communicates with the air inlet channel, the support can be stably inserted into the plug-in groove, making the installation position of the filter assembly more precise and facilitating quick disassembly and maintenance.

[0015] In one possible implementation, the suction head provided in this application has the insertion groove extending along a first direction and the air inlet channel extending along a second direction, wherein the first direction is perpendicular to the second direction.

[0016] In this way, the insertion slot is perpendicular to the air inlet channel, allowing the support to be inserted vertically, thus avoiding direct obstruction of the airflow in the air inlet channel.

[0017] In one possible implementation, the suction head provided in this application has the filter assembly detachably connected to the housing;

[0018] When the filter assembly is in the first state, the protrusion is located inside the air inlet channel, and the support is inserted into the insertion slot along the first direction; in the first direction, the protrusion is disposed opposite to the inner wall of the air inlet channel;

[0019] When the filter assembly is in the second state, the protrusion is located outside the air inlet channel, and the protrusion can be moved into or out of the housing through the insertion slot.

[0020] This ensures that inhaled impurities are forced through the filter element, rather than escaping through the gap between the support and the housing. The filter element can be moved into or out of the housing along the insertion slot, facilitating user cleaning or replacement. This extends the lifespan of the suction assembly while reducing maintenance costs.

[0021] In one possible implementation, when the support portion of the suction head provided in this application is inserted into the insertion slot, the axis of the filter element is parallel or approximately parallel to the axis of the air inlet channel.

[0022] In this way, the airflow can pass through the filter in a straight line, reducing airflow bends or turbulence and ensuring that impurities are efficiently intercepted. It also reduces turbulence and flow during airflow, thereby lowering noise caused by airflow disturbance.

[0023] In one possible implementation, the suction head provided in this application includes a filter assembly comprising an abutment portion located outside the housing;

[0024] When the filter assembly is in the first state, the abutting part abuts against the housing.

[0025] This improves the stability of the filter components and further reduces noise caused by vibration.

[0026] In one possible implementation, the suction head provided in this application has a sealing element provided in the support portion, and the sealing element is sleeved on the outside of the support portion.

[0027] When the filter assembly is in the first state, the outer surface of the seal abuts against the inner wall of the insertion groove.

[0028] This effectively prevents unfiltered airflow from entering the air intake channel through the gap between the support and the housing, ensuring that all inhaled impurities must pass through the filter element, avoiding circumvention or leakage. It reduces the risk of the suction assembly becoming clogged or damaged due to direct entry of impurities, while also ensuring the cleanliness of the airflow within the air intake channel.

[0029] In addition, the seal abuts against the inner wall of the insertion groove, fixing the support part through friction to prevent it from shifting due to vibration and ensuring the continuity of the filtration effect.

[0030] In one possible implementation, the suction head provided in this application has a rectifier structure provided in the mounting hole, the rectifier structure being used to support the filter element.

[0031] In this way, the rectifier structure set in the mounting hole can organize the airflow entering the air inlet channel, reduce turbulence and flow, and make the airflow pass through the filter more evenly.

[0032] In one possible implementation, the suction head provided in this application includes a rectification structure comprising a support ring and at least one support rod;

[0033] The support rod connects the support ring and the inner wall of the mounting hole;

[0034] Both the support ring and the support rod are used to support the filter element.

[0035] In this way, the support rod and support ring guide the airflow direction, reduce the resistance of the airflow when passing through the filter element, reduce turbulence, reduce noise, and at the same time support the filter element and improve its stability.

[0036] In one possible implementation, the suction head provided in this application has the rectifying structure disposed on the side of the mounting hole near the suction assembly in the depth direction of the mounting hole.

[0037] This increases the installation space for the filter element and improves its installation stability. Furthermore, by placing the rectifying structure on the side of the mounting hole closer to the suction assembly, the filter element receives support during airflow filtration, preventing displacement.

[0038] In one possible implementation, the suction head provided in this application has a ratio of the area of ​​the rectifying structure to the cross-sectional area of ​​the mounting hole that is greater than or equal to 0.05 and less than or equal to 0.8 in a cross-section parallel to the mounting hole.

[0039] This effectively regulates airflow and reduces turbulence, while avoiding airflow blockage caused by an excessively large rectifying structure. It ensures efficient airflow guidance as the air passes through the filter components, while maintaining sufficient flow cross-sectional area to reduce resistance.

[0040] In one possible implementation, the ratio of the thickness of the protrusion to the thickness of the support portion in the suction head provided in this application is greater than or equal to 2 and less than or equal to 3.

[0041] In this way, the protruding part can be made lightweight while ensuring structural strength.

[0042] In one possible implementation, the suction head provided in this application further includes a boiler assembly, which is located inside the housing, and a suction channel is formed between the boiler assembly and the housing, and the suction channel is connected to the air inlet channel;

[0043] The surface of the support portion facing away from the air inlet channel is smoothly connected to the side wall of the air intake channel.

[0044] This avoids the abrupt airflow changes caused by traditional right-angle or stepped structures. When the airflow enters the suction channel from the intake channel, it can flow along a continuous and smooth path, reducing turbulence and eddies caused by structural abrupt changes, thereby reducing wind resistance and energy consumption.

[0045] In one possible implementation, the suction head provided in this application has an air guide groove on the support portion, and the air guide groove communicates with the mounting hole.

[0046] In this way, the air guide duct reduces turbulence caused by abrupt structural changes or complex cross-sectional shapes within the air intake channel by guiding airflow along a predetermined path, thereby reducing airflow resistance. Furthermore, the air guide duct increases the passage area of ​​airflow as it flows from the suction channel to the mounting hole, improving flow efficiency.

[0047] In one possible implementation, the suction head provided in this application has the air guide groove located on the side of the support portion facing the air inlet channel; and / or, the air guide groove is located on the side of the support portion away from the air inlet channel.

[0048] This improves the flexibility of the filter components, enabling them to adapt to different air intake directions or airflow intensities, and further enhances the versatility of the technology.

[0049] In one possible implementation, the suction head provided in this application has a fixing part provided inside the housing;

[0050] The support portion is provided with a fixing head, and at least a portion of the fixing head protrudes relative to the support portion in the thickness direction of the support portion, and the fixing head is connected to the fixing portion.

[0051] This ensures that the support can only be inserted into the socket of the housing in the correct direction, thus preventing incorrect insertion.

[0052] Secondly, this application provides an ironing machine, including a body and an ironing head as described above disposed on the body.

[0053] Thus, irons equipped with the aforementioned suction heads can effectively trap dust, hair, fabric debris, and other impurities from clothing. This reduces the impact on airflow resistance, minimizes noise and vibration caused by airflow turbulence, and enhances the user experience.

[0054] The steam ironing head and steamer provided in this application include a housing, a suction assembly, and a filter assembly. The suction assembly is disposed within the housing and has an air inlet channel. The filter assembly includes a support portion, a protrusion, and a filter element. The support portion is inserted into the housing and is located outside the air inlet channel. The protrusion protrudes towards the air inlet channel relative to the support portion, with at least a portion of the protrusion located within the air inlet channel. The protrusion has a mounting hole, and the filter element is disposed within the mounting hole. By placing the protrusion of the filter assembly within the air inlet channel, the intake airflow must first pass through the filter element. This effectively intercepts dust, hair, fabric debris, and other impurities from clothing, preventing them from entering the suction assembly and thus avoiding blockage or damage. The protrusion protrudes towards the air inlet channel, and a portion of the protrusion is located within the channel, utilizing the airflow direction to ensure efficient interception of impurities. Furthermore, this arrangement reduces the impact on airflow resistance while ensuring filtration effectiveness, lowering noise and vibration caused by airflow turbulence and improving the user experience.

Detailed Implementation

[0075] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0076] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0077] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0078] In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise specified precisely.

[0079] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0080] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0081] With the improvement of living standards, ironing machines, as a household appliance that can iron clothes, have become increasingly popular. As an indispensable piece of equipment in homes and professional laundry rooms, the main function of ironing machines is to smooth clothes, remove wrinkles, and restore the smoothness and luster of clothes through high temperature and pressure.

[0082] For example, an ironing machine typically has an ironing panel with a steam outlet. The user holds the ironing machine so that the ironing panel comes into contact with the clothes to be ironed, and uses the high-temperature steam sprayed from the steam outlet to iron the clothes, which loosens the fabric fibers and reduces wrinkles.

[0083] In related technologies, some ironing machines are usually equipped with suction components. The ironing panel has an air intake. The suction component generates suction force, which adsorbs the clothes onto the ironing panel through the air intake to ensure stable contact between the ironing panel and the clothes and to ensure the ironing effect.

[0084] However, when ironing clothes, dust, hair, and fabric debris on the clothes will inevitably be sucked into the suction unit by the suction, causing blockage or even damage to the suction unit. For example, if hair on the clothes enters the suction unit through the air inlet, the hair may become entangled in the motor inside the suction unit, causing blockage or damage to the motor.

[0085] Based on the aforementioned technical problems, this application provides a suction head and an ironing machine. In this solution, the suction head includes a housing, a suction assembly, and a filter assembly. The suction assembly is disposed within the housing and has an air inlet channel. The filter assembly includes a support portion, a protrusion, and a filter element. The support portion is inserted into the housing and is located outside the air inlet channel. The protrusion protrudes towards the air inlet channel relative to the support portion, with at least a portion of the protrusion located within the air inlet channel. The protrusion has a mounting hole, and the filter element is disposed within the mounting hole. By placing the protrusion of the filter assembly within the air inlet channel, the intake airflow must first pass through the filter element. This effectively intercepts dust, hair, fabric debris, and other impurities from clothing, preventing them from entering the suction assembly and thus avoiding blockage or damage. The protrusion protrudes towards the air inlet channel, and a portion of the protrusion is located within the channel, utilizing the airflow direction to ensure efficient interception of impurities. Furthermore, this arrangement ensures filtration effectiveness while reducing the impact on airflow resistance, minimizing noise and vibration caused by airflow turbulence, and improving the user experience.

[0086] To facilitate understanding, the application scenarios of the embodiments of this application will be described first.

[0087] The steaming head and ironing machine provided in this application can be applied to clothing manufacturing, storage, sales, or laundry services. The clothing to be ironed by the steaming machine should be interpreted broadly, including but not limited to clothes, trousers, and other items for wearing, as well as fabrics such as curtains, sheets, and duvet covers. This application does not specifically limit this, and will be collectively referred to as "clothing" below, without further specific examples.

[0088] It should be noted that, Figures 1 to 9 This diagram illustrates a simplified representation of the steam suction head and other components of the ironing machine. The specific structures of the steam suction head and other components of the ironing machine are not limited to these examples. Figures 1 to 9 of examples.

[0089] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0090] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, a steaming head and an ironing machine are provided. The steaming head provided in this application can be used in an ironing machine. The user can hold the ironing machine and make the ironing plate 10 of the steaming head contact the clothing to iron it. The ironing plate 10 can be a cast aluminum sole plate, or it can be a sole plate made of other heat-conducting metal or alloy material. This application does not specifically limit the specific material of the ironing plate 10.

[0091] It should also be noted that the X, Y, and Z directions shown in the attached diagram are mutually perpendicular in three-dimensional space.

[0092] Reference Figures 3 to 6 As shown, and in combination Figure 1 and Figure 2 The present application provides a suction head including a housing 100, a suction component 200 and a filter component 300. The suction component 200 is disposed inside the housing 100 and has an air inlet channel 201.

[0093] For example, when ironing clothes, the suction component 200 generates negative pressure, and the ironing panel 10 has an air inlet 20. The clothes are adsorbed onto the ironing panel 10 through the air inlet 20 to ensure the ironing effect.

[0094] Multiple air inlets 20 are provided, and the multiple air inlets 20 are arranged in a ring on the ironing panel 10. This ensures that the clothes attached to the ironing panel 10 are subjected to uniform suction, ensuring the stretching of the clothes in multiple directions and improving the ironing effect.

[0095] The heating head also includes a boiler assembly 400, which is located inside the housing 100. An air intake channel 401 is formed between the boiler assembly 400 and the housing 100, and the air intake channel 401 is connected to the air inlet channel 201. The boiler assembly 400 has a steam outlet.

[0096] The ironing panel 10 is provided with a steam port 30, and the steam outlet is connected to the steam port 30.

[0097] Understandably, an ironing machine can be equipped with a water tank and a water pump. The water pump delivers water from the tank to the boiler assembly 400, which can generate heat and heat the water to its boiling point to produce high-temperature steam.

[0098] In this way, the high-temperature steam can be discharged sequentially through the steam outlet and steam port 30, thereby using the high-temperature steam to iron out the wrinkles on the clothes.

[0099] The filter assembly 300 includes a support 310, a protrusion 320, and a filter element 330. The support 310 is inserted into the housing 100 and is located outside the air inlet channel 201. The protrusion 320 protrudes toward the air inlet channel 201 relative to the support 310, and at least a portion of the protrusion 320 is located inside the air inlet channel 201.

[0100] The protrusion 320 is provided with a mounting hole 3201, and the filter element 330 is disposed in the mounting hole 3201.

[0101] By positioning the protrusion 320 of the filter assembly 300 within the air inlet channel 201, the intake airflow must first pass through the filter element 330. It can be understood that when the iron is ironing clothes, the suction assembly 200 generates negative pressure, and the airflow at the ironing panel 10 flows sequentially through the air intake port 20 and the air intake channel 401 into the air inlet channel 201. For example... Figure 4 The middle arrow indicates the direction of airflow.

[0102] By placing the filter component 300 between the air intake channel 401 and the air inlet channel 201, it can effectively intercept impurities such as dust, hair, and fabric debris on clothing, preventing them from entering the suction component 200 and thus avoiding blockage or damage to the suction component 200.

[0103] The protrusion 320 protrudes towards the air inlet channel 201, and part of the protrusion 320 is located inside the channel. By utilizing the airflow direction, impurities are effectively intercepted. In addition, the above arrangement can reduce the impact on airflow resistance while ensuring the filtration effect, reduce noise and vibration caused by airflow turbulence, and improve the user experience.

[0104] To further reduce noise, filter element 330 can be made of foam sponge or other porous materials. Of course, filter element 330 can also be a filter screen. It can also be a multi-layered structure of foam sponge and filter screen, capable of intercepting large particles and adsorbing fine dust, adapting to the cleaning needs of different scenarios.

[0105] The housing 100 is provided with a plug groove 101, which is connected to the air inlet channel 201, and the support part 310 is inserted into the plug groove 101.

[0106] By providing a connector slot 101 on the housing 100 that communicates with the air inlet channel 201, the support 310 can be stably inserted into the connector slot 101. This design allows for more precise installation of the filter assembly 300, thereby maximizing filtration efficiency and preventing airflow from bypassing the filter element 330 and directly entering the suction assembly 200. The connector slot 101 provides a standardized installation interface for the filter assembly 300, facilitating quick installation, removal, and maintenance. Users can replace the filter element 330 through a plug-and-play operation, improving ease of use.

[0107] In one possible implementation, the insertion slot 101 extends along a first direction, and the air inlet channel 201 extends along a second direction, with the first direction being perpendicular to the second direction.

[0108] Reference Figure 3 and Figure 4 The X, Y, and Z arrows indicate the directions, with the first direction being the direction indicated by arrow Z and the second direction being the direction indicated by arrow Y. The insertion slot 101 is perpendicular to the air inlet channel 201, allowing the support 310 to be inserted vertically, avoiding direct obstruction of airflow within the air inlet channel 201. Simultaneously, the extension direction of the insertion slot 101 creates spatial isolation with the air inlet channel 201, reducing airflow turbulence and lowering noise and vibration. The insertion slot 101 provides physical restraint for the support 310, preventing the filter assembly 300 from shifting due to vibration or airflow impact during use, ensuring the continuity of the filtration effect.

[0109] In addition, the vertical arrangement of the insertion slot 101 and the air inlet channel 201 saves internal space in the housing 100, making the steaming head structure more compact and suitable for different models of ironing machines.

[0110] In one possible implementation, the filter assembly 300 is detachably connected to the housing 100.

[0111] When the filter assembly 300 is in the first state, the protrusion 320 is located in the air inlet channel 201, and the support 310 is inserted into the insertion slot 101 along the first direction; in the first direction, the protrusion 320 is disposed opposite to the inner wall of the air inlet channel 201.

[0112] When the filter assembly 300 is in the second state, the protrusion 320 is located outside the air inlet channel 201, and the protrusion 320 can be moved into or out of the housing 100 through the insertion slot 101.

[0113] Here, the first state of the filter assembly 300 can be understood as the working state in which the filter assembly 300 is installed. At this time, the protrusion 320 is located inside the air inlet channel 201. In the first direction, the protrusion 320 is positioned opposite to the inner wall of the air inlet channel 201, ensuring that at least part of the structure of the protrusion 320 is located inside the air inlet channel 201. The protrusion 320 has a mounting hole 3201 for installing the filter element 330, forming a forced airflow guide to ensure that the inhaled impurities must pass through the filter element 330, avoiding bypass or leakage. The first state of the filter assembly 300 can also be understood as the maintenance state. The user can insert and remove the filter assembly 300, and the protrusion 320 can be moved out of the air inlet channel 201. The filter assembly 300 can be completely removed from the housing 100 through the insertion slot 101, facilitating cleaning or replacement of the filter element 330. The filter assembly 300 can be quickly installed and removed through the insertion slot 101. The user can complete the maintenance manually without additional tools, lowering the barrier to entry.

[0114] In one possible implementation, when the support 310 is inserted into the insertion slot 101, the axis of the filter 330 is parallel or approximately parallel to the axis of the air inlet channel 201.

[0115] When the axis of the filter element 330 is parallel or nearly parallel to the axis of the air inlet channel 201, the airflow can pass through the filter element 330 in a straight line, reducing airflow bends or turbulence and ensuring that impurities are efficiently intercepted. This avoids airflow deviation or localized flow around the filter element 330 due to its tilt, thereby improving the filtration effect.

[0116] The parallel axial direction minimizes resistance as airflow passes through the filter element 330, reducing the impact on the suction force of the suction assembly 200 and ensuring the negative pressure environment required for the normal operation of the iron. Furthermore, the axis of the filter element 330 is aligned with the airflow direction, reducing turbulence and flow disturbances, thereby lowering noise caused by airflow disturbances and improving the user experience.

[0117] To improve the stability of the filter assembly 300, the filter assembly 300 includes an abutment portion 340 located on the outside of the housing 100. When the filter assembly 300 is in its first state, i.e., when it is installed and in operation, the abutment portion 340 abuts against the housing 100. Specifically, the abutment portion 340 is integrally formed with the support portion 310, which improves the structural strength of the abutment portion 340. Furthermore, the higher stability of the filter assembly 300 can prevent vibration from generating significant noise.

[0118] In one possible implementation, the support portion 310 is provided with a relief groove 3101 on the side near the abutment portion 340, and the abutment portion 340 is provided with a raised edge, which is at least spaced from the housing 100. The relief groove 3101 can be achieved by bending the support portion 310. When the user disassembles the filter assembly 300, he first presses the raised edge, and the support portion 310 tilts to one side. Part of the side wall of the insertion groove 101 enters the relief groove 3101. At this time, the protrusion 320 disengages from the air inlet channel 201, and the support portion 310 can be pulled out.

[0119] In one possible implementation, refer to Figure 5 and Figure 6 As shown, and in combination Figure 3 and Figure 4 The support part 310 is provided with a sealing element 500, which is sleeved on the outside of the support part 310.

[0120] When the filter assembly 300 is in the first state, the outer surface of the seal 500 abuts against the inner wall of the insertion groove 101.

[0121] When the filter assembly 300 is in its first state, i.e., its working state, the outer surface of the sealing member 500, which is sleeved on the outside of the support 310, abuts against the inner wall of the insertion groove 101, forming a physical seal. This effectively blocks unfiltered airflow from entering the air inlet channel 201 through the gap between the support 310 and the housing 100, ensuring that all inhaled impurities must pass through the filter element 330, avoiding circumvention or leakage. By forcing airflow through the filter element 330, the risk of the suction assembly 200 being blocked or damaged due to direct entry of impurities is reduced, while ensuring the cleanliness of the airflow within the air inlet channel 201.

[0122] In practice, the sealing element 500 can be made of rubber, silicone, or other elastic materials. It compensates for the machining tolerances between the support portion 310 and the insertion groove 101, preventing loosening or shaking due to dimensional deviations and enhancing the installation stability of the filter assembly 300. During the operation of the ironing machine, the vibration generated by suction may affect the positioning of the filter assembly 300. The sealing element 500 abuts against the insertion groove 101, fixing the support portion 310 through friction to prevent displacement due to vibration and ensuring the continuity of the filtration effect.

[0123] Continue to refer to Figure 5 and Figure 6 As shown, in one possible implementation, a rectifier structure 600 is provided within the mounting hole 3201, which also serves to support the filter element 330. The rectifier structure 600 within the mounting hole 3201 can regulate the airflow entering the air inlet channel 201, reducing turbulence and allowing the airflow to pass through the filter element 330 more evenly. Specifically, the rectifier structure 600 includes a support ring 610 and at least one support rod 620. The support rod 620 connects the support ring 610 and the inner wall of the mounting hole 3201. Both the support ring 610 and the support rod 620 are used to support the filter element 330. In one specific implementation, multiple support rods 620 are provided, evenly distributed around the circumference of the support ring 610. It can be understood that the area inside the support ring 610 is the first region, and the area between the support ring 610 and the inner wall of the mounting hole 3201 is the second region. Each support rod 620 evenly divides the second region, thus forming multiple areas for airflow passage. The rectifying structure 600 guides the airflow direction, reducing the resistance of the airflow passing through the filter element 330. Furthermore, by setting the rectifying structure 600, the airflow can pass evenly through the first and second regions, reducing turbulence and further reducing noise generated during airflow. The support ring 610 and support rods 620 not only rectify the airflow but also support the filter element 330, preventing displacement or deformation due to airflow impact or vibration, thus ensuring the continuity of the filtration effect.

[0124] In the depth direction of mounting hole 3201, such as Figure 6 In the Y-direction, the rectifying structure 600 is positioned on the side of the mounting hole 3201 near the suction assembly 200. Positioning the rectifying structure 600 on the side of the mounting hole 3201 near the suction assembly 200 increases the installation space for the filter element 330 and improves its installation stability. When the filter element 330 is filtering airflow, the rectifying structure 600 provides a certain supporting force to prevent displacement of the filter element 330.

[0125] The support ring 610 and support rod 620 can be made of high-temperature and corrosion-resistant materials, such as plastic or metal, to meet the usage requirements of the high-temperature steam environment of the ironing machine, while the physical support enhances the structural stability of the filter assembly 300.

[0126] Of course, refer to Figure 7 As shown, the rectifier structure 600 can be omitted in the mounting hole 3201, and the filter element 330 can be directly fixed in the mounting hole 3201, which can further simplify the structure and reduce costs.

[0127] In one possible implementation, within a cross-section parallel to the mounting hole 3201, the ratio of the area of ​​the rectifier structure 600 to the cross-sectional area of ​​the mounting hole 3201 is greater than or equal to 0.05 and less than or equal to 0.8.

[0128] By configuring the above method, the ratio of the area of ​​the rectifying structure 600 to the cross-sectional area of ​​the mounting hole 3201 is controlled within the range of 0.05-0.8. This effectively regulates the airflow, reduces turbulence, and avoids airflow blockage caused by an excessively large rectifying structure 600. This design ensures efficient airflow guidance when passing through the filter assembly 300, while retaining sufficient flow cross-sectional area to reduce resistance. If the ratio of the area of ​​the rectifying structure 600 to the cross-sectional area of ​​the mounting hole 3201 is too small, such as less than 0.05, the rectifying structure 600's effect on airflow regulation is insufficient, which may lead to airflow turbulence and decreased filtration efficiency. If the ratio is too large, such as greater than 0.8, the airflow channel becomes narrower, and the suction force decreases significantly. The ratio of the area of ​​the rectifying structure 600 to the cross-sectional area of ​​the mounting hole 3201 can be controlled by adjusting the thickness of the support ring 610 and the support rod 620. This embodiment does not limit how the support ring 610 and the support rod 620 are set to different thicknesses.

[0129] In one possible implementation, the ratio of the thickness of the protrusion 320 to the thickness of the support 310 is greater than or equal to 2 and less than or equal to 3.

[0130] By controlling the thickness ratio of the protrusion 320 to the support 310 within the range of 2-3, the protrusion 320 achieves lightweighting while ensuring structural strength. A thinner protrusion 320 reduces obstruction of airflow within the air inlet channel 201, preventing airflow turbulence or localized pressure loss due to excessive structural thickness, thereby reducing the energy consumption of the suction assembly 200. Furthermore, if the thickness ratio of the protrusion 320 to the support 310 is too small, it will affect the stability of the protrusion 320 and reduce the installation space of the filter element 330; if the thickness ratio is too large, the protrusion 320 may not be able to pass through the insertion slot 101, causing interference between components.

[0131] In one possible implementation, to further reduce airflow noise, the surface of the support portion 310 facing away from the air inlet channel 201 is smoothly connected to the side wall of the suction channel 401. This smooth connection between the support portion 310 and the side wall of the suction channel 401 avoids abrupt airflow changes caused by traditional right-angle or stepped structures. When airflow enters the suction channel 401 from the air inlet channel 201, it can flow along a continuous, smooth path, reducing turbulence and eddies caused by structural abrupt changes, thereby reducing wind resistance and energy consumption. Specifically, this can be achieved by altering the outer surface of the boiler assembly 400 and the inner surface of the shell 100, thus ensuring a smooth connection between the suction channel 401 and the surface of the support portion 310 facing away from the air inlet channel 201.

[0132] In one possible implementation, in another embodiment of this application, reference is made to... Figure 8 and Figure 9 As shown, the support part 310 is provided with an air guide groove 3102, which is connected to the mounting hole 3201. The air guide groove 3102 can be an air guide groove 3102 excavated on the support part 310.

[0133] The air guide slot 3102 guides airflow along a preset path, reducing turbulence caused by structural abrupt changes or complex cross-sectional shapes within the air inlet channel 201, thereby lowering airflow resistance. This allows the suction assembly 200 to maintain the same suction power with lower energy consumption, improving energy efficiency. The air guide slot 3102 can evenly direct airflow to the mounting hole 3201 where the filter element 330 is located, avoiding local airflow overload or dead zones, ensuring that all areas of the filter element 330 can effectively intercept impurities. The air guide slot 3102 is connected to the mounting hole 3201, allowing sucked-in dust, hair, and other impurities to be actively guided to the location of the filter element 330, reducing the risk of impurities directly entering the core area of ​​the suction assembly 200 and reducing the probability of blockage. In addition, the air guide slot 3102 increases the passage area of ​​airflow during its flow from the suction channel 401 to the mounting hole 3201, improving flow efficiency. This further enhances the overall suction efficiency.

[0134] In one specific implementation, the air guide slot 3102 is located on the side of the support portion 310 facing the air inlet channel 201, and / or, the air guide slot 3102 is located on the side of the support portion 310 away from the air inlet channel 201. When air guide slots 3102 are provided on both sides of the support portion 310 facing or away from the air inlet channel 201, the airflow conduction area can be further increased, adapting to scenarios with different air inlet directions or airflow intensities, and improving the smoothness of airflow.

[0135] In one possible implementation, a fixing part 110 is provided inside the housing 100. A fixing head 3103 is provided on the support part 310. At least a portion of the fixing head 3103 protrudes relative to the support part 310 in the thickness direction of the support part 310. The fixing head 3103 is connected to the fixing part 110. Specifically, the fixing head 3103 is a snap-fit ​​connector, and the fixing part 110 is a recessed part; the snap-fit ​​connector engages with the recessed part. The fixing head 3103 is located at the end of the support part 310 opposite to the abutment part 340.

[0136] The fixing head 3103 protrudes in the thickness direction of the support portion 310 and connects with the fixing portion 110 inside the housing 100, forming a mechanical interlocking or snap-fit ​​structure. By physically limiting the support portion 310, it prevents it from dislodging from the insertion slot 101 under the suction force of the suction assembly 200, restricting the axial displacement of the support portion 310 along the insertion slot 101, and simultaneously resisting lateral loosening caused by airflow impact within the air inlet channel 201. Furthermore, it ensures that the support portion 310 can only be inserted into the insertion slot 101 of the housing 100 in the correct direction, thus preventing incorrect insertion. As the connection point between the support portion 310 and the housing 100, the fixing head 3103 disperses the suction force and airflow impact force of the suction assembly 200 to the fixing portion 110 of the housing 100, avoiding stress concentration at the contact edge between the support portion 310 and the insertion slot 101, and extending the service life of both.

[0137] In one possible implementation, this application provides an ironing machine, including a main body and a suction head as described above, disposed on the main body. The specific structure of the suction head has been described above and will not be repeated here. An ironing machine equipped with the suction head can effectively trap dust, hair, fabric debris, and other impurities from clothing. This reduces the impact on airflow resistance, lowers noise and vibration caused by airflow turbulence, and improves the user experience.

[0138] The implementation principle of the steaming head and ironing machine according to the embodiments of this application is as follows: The steaming head includes a housing 100, a suction assembly 200, and a filter assembly 300. The suction assembly 200 is disposed inside the housing 100 and has an air inlet channel 201. The filter assembly 300 includes a support portion 310, a protrusion 320, and a filter element 330. The support portion 310 is inserted into the housing 100 and is located outside the air inlet channel 201. The protrusion 320 protrudes towards the air inlet channel 201 relative to the support portion 310, and at least a portion of the protrusion 320 is located inside the air inlet channel 201. The protrusion 320 is provided with a mounting hole 3201, and the filter element 330 is disposed inside the mounting hole 3201. By placing the protrusion 320 of the filter assembly 300 inside the air inlet channel 201, the intake airflow must first pass through the filter element 330. It can effectively intercept dust, hair, fabric debris, and other impurities from clothing, preventing them from entering the suction component 200 and thus avoiding blockage or damage to the suction component 200. The protrusion 320 protrudes towards the air inlet channel 201, and part of the protrusion 320 is located inside the channel. By utilizing the airflow direction, it ensures that impurities are efficiently intercepted. In addition, the above-mentioned arrangement can reduce the impact on airflow resistance while ensuring filtration effect, reduce noise and vibration caused by airflow turbulence, and improve user experience.
