Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a suction-type steam brush with a detachable filter structure. Background Technology

[0002] Steam brushes with suction are commonly used for ironing and garment care. They utilize a steam generator to produce high-temperature steam to soften wrinkles in fabrics. To enhance ironing results and simultaneously clean the garment surface, existing technologies have increasingly incorporated integrated suction structures. These combine steam ironing with negative pressure suction, allowing users to iron clothes with one hand while simultaneously removing hair, dust, lint, and other debris from the garment surface. This significantly improves the convenience and comprehensiveness of garment care.

[0003] Existing suction-type steam brushes typically consist of a housing, a panel assembly mounted at the front of the housing, and a steam generating assembly and a suction assembly built into the housing. The housing contains a suction channel connected to the suction assembly. The panel assembly is divided into a steam panel for spraying steam and a suction panel for negative pressure suction. The suction panel has several suction ports. When the suction assembly operates, it generates negative pressure, causing airflow to carry debris from the surface of clothing through the suction ports into the suction channel, thus collecting the debris. To prevent debris from entering the suction assembly and causing damage, existing suction-type steam brushes usually use a filter screen between the suction channel and the suction ports. However, the existing structure has significant technical drawbacks: the suction panel and filter screen are mostly installed independently, requiring separate steps for disassembly and cleaning, making the process cumbersome and prone to problems such as lost parts or missed cleaning. Utility Model Content

[0004] In order to overcome at least some of the shortcomings of the prior art, this application provides a suction-type steam brush with a detachable filter structure, which can simultaneously remove the suction panel, filter support and filter screen, realize the integrated disassembly and cleaning of the three, and simplify the cleaning operation process.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A suction-type steam brush with a detachable filter structure includes a housing, a panel assembly mounted on the front end of the housing, and a steam generating assembly and a suction assembly mounted inside the housing. The housing has a suction channel communicating with the suction assembly. The panel assembly includes a steam panel and a suction panel. The suction panel includes a panel body, a filter support detachably connected to the panel body, and a filter installed on the filter support. The panel body is detachably connected to the housing. The filter support is located on the rear side of the panel body. The panel body has at least one suction port. The filter is located between the suction port and the suction channel, so that the suction port and the suction channel are connected through the filter.

[0007] In the above technical solution, by detachably assembling the panel body to the housing, and placing the filter support on the rear side of the panel body and installing the filter on the filter support, when performing routine cleaning and maintenance of the steam brush, only the panel body needs to be removed from the housing to simultaneously remove the filter support and filter. This achieves integrated disassembly, cleaning, and maintenance of the panel body, filter support, and filter, simplifying the cleaning process and effectively improving the convenience of use and maintenance for users.

[0008] Preferably, the filter screen and the filter screen support are integrally formed.

[0009] Alternatively, the filter screen is fixed to the filter screen support.

[0010] In the above technical solutions, the filter screen and filter screen support are designed as a single molded structure, or the filter screen is firmly fixed to the filter screen support, enhancing the connection strength and stability between the filter screen and the filter screen support. The single molded structure eliminates independent connection interfaces between components, fundamentally avoiding the risk of the filter screen loosening, shifting, or falling off due to vibration, impact, or water erosion during use or cleaning. Similarly, fixing the filter screen to the filter screen support through welding, bonding, or other methods also provides a reliable connection, ensuring that the filter screen always remains in the preset position. This guarantees the continuous effectiveness of the filtration function between the air inlet and the air intake channel, preventing hair, dust, and other debris from entering the air intake channel and causing blockage or damage to the air intake components, thereby extending the service life of the suction-type steam brush and improving the overall reliability of the product and the user experience.

[0011] Preferably, the filter screen is detachably connected to the filter screen support.

[0012] In the above technical solution, when the filter screen becomes clogged due to adsorbed debris, the user can directly separate the filter screen for individual cleaning or replacement when removing the panel body, filter screen bracket and filter screen from the housing. The cleaning is more thorough and the replacement cost is lower. In addition, the filter screen does not need to be fixed to the filter screen bracket in advance, which simplifies the manufacturing process and reduces production costs.

[0013] Preferably, the filter screen and the filter screen support are separate structures, and the filter screen is clamped between the two when the panel body and the filter screen support are connected.

[0014] In the above technical solution, the filter screen is designed to be separate from the filter screen support, and is clamped and fixed when the panel body is connected to the filter screen support. This ensures the stability of the filter screen during the operation of the suction-type steam brush, preventing it from shifting or falling off, thereby ensuring the normal operation of the suction assembly and the cleanliness of the suction channel. Furthermore, when the filter screen becomes clogged due to adsorbed debris, the user can directly separate the filter screen for individual cleaning or replacement by removing the panel body, filter screen support, and filter screen from the housing. This results in more thorough cleaning, lower replacement costs, and simplifies the manufacturing process by eliminating the need for pre-fixation to the filter screen support, thus reducing production costs.

[0015] Preferably, the panel body is sleeved on the front end of the housing, the filter support is located on the inner side of the panel body, the filter support is located on the front end of the housing, and the front end of the housing and the inner wall of the panel body clamp the filter support together.

[0016] In the above technical solution, when the panel body is connected to the housing, the front end of the housing and the inner wall of the panel body can clamp the filter support in the front-to-back direction, so that the filter support is firmly fixed between the panel body and the housing. This effectively solves the problem of possible loosening and displacement of the filter support, thereby ensuring the stability of the filter and the sealing of the air intake channel. Since the filter support is clamped and fixed through the connection between the panel body and the housing, the filter support can also be released when the panel body is disassembled, which facilitates the removal, cleaning or replacement of the filter and improves the product's maintenance convenience. Furthermore, since the filter support is located on the inner circumference of the panel body, it will not fall off the housing when the panel body is assembled, thus avoiding the risk of accidental detachment of the filter support and filter during use, and also avoiding the situation where only the filter support is removed and cleaning is missed due to misoperation when disassembling the panel body.

[0017] Preferably, the panel body is sleeved on the front end of the housing, the panel body is provided with an elastic sheet that can be elastically deformed in the radial direction, the inner wall of the elastic sheet is provided with a first flange, the outer wall of the front end of the housing is provided with a first groove that matches the first flange, the panel body and the housing are detachably connected through the cooperation of the first flange and the first groove, the elastic sheet is provided with a disassembly handle that facilitates the operation of the elastic sheet to deform radially, and the disassembly handle is located on the lower side of the panel body.

[0018] In the above technical solution, the connection between the panel body and the housing achieves reliable locking and convenient disassembly. When the panel body is fitted onto the front end of the housing, the first flange on the elastic sheet automatically engages with the first groove on the housing, forming a stable snap-fit ​​connection. This effectively prevents the panel body from accidentally falling off during use and ensures the overall structural stability of the suction-type steam brush. Simultaneously, when cleaning or replacing the filter, the user only needs to operate the disassembly handle located on the underside of the panel body to cause radial deformation of the elastic sheet, releasing the locking engagement between the first flange and the first groove, thus easily removing the panel body from the housing. To facilitate user operation, the elastic sheet is equipped with a disassembly handle, providing a point of force for the user to pull or push to cause radial deformation of the elastic sheet, thereby releasing the locking state. The disassembly handle is typically located on the underside of the panel body, making it less prone to accidental activation during product use and maintaining the overall simplicity of the product's appearance.

[0019] Preferably, the inner wall of the panel body at the position opposite to the elastic sheet is provided with a second flange, and the outer wall of the front end of the housing is provided with a second groove that engages with the second flange.

[0020] In the above technical solution, a second flange is added at the position opposite to the elastic sheet of the panel body, and a second groove is provided on the outer wall of the front end of the housing to engage with the second flange. This achieves multi-point or symmetrical locking between the panel body and the housing, enhances the connection stability between the panel assembly and the housing, and effectively prevents the panel body from shaking or accidentally falling off due to vibration or external force during use.

[0021] Preferably, the panel body is tightly connected to the housing, and the lower side of the panel body is provided with a protruding handle for easy finger application.

[0022] In the above technical solution, the panel body and the housing are connected by a tight fit, ensuring the structural stability of the suction-type steam brush in operation. Meanwhile, a raised handle is provided on the underside of the panel body for easy finger application, providing the user with a clear and ergonomic operating point. When cleaning or replacing the filter, the user can easily grasp the raised handle and apply appropriate force to easily detach the tightly fitted panel body from the housing.

[0023] Preferably, a temporary storage cavity is provided between the filter screen and the air intake. The filter screen covers the opening of the temporary storage cavity near the air intake channel. The side of the temporary storage cavity near the air intake is connected to the air intake. The opening of the temporary storage cavity is set after the panel body and the filter screen bracket are disassembled.

[0024] Preferably, a temporary storage cavity is provided between the filter screen and the air intake, the filter screen covers the opening of the temporary storage cavity near the air intake channel, and the side of the temporary storage cavity near the air intake is connected to the air intake.

[0025] In the above technical solution, the temporary storage chamber is a space located between the filter and the air intake, used to temporarily collect and retain hair, dust, and lint trapped by the filter. The temporary storage chamber can be a simple groove structure, with sufficient depth and width to accommodate a certain amount of debris. By setting up the temporary storage chamber and placing the filter between the temporary storage chamber and the air intake channel, the above technical solution allows the inhaled hair, dust, and lint to first enter the temporary storage chamber and be trapped by the filter. This effectively extends the cleaning cycle of the filter, reduces the risk of direct filter clogging, and thus maintains the continuous suction efficiency of the suction-type steam brush.

[0026] Preferably, the main body of the temporary storage cavity is formed by a groove structure on the filter support; or, the main body of the temporary storage cavity is formed by a groove structure on the panel body; or, the main body of the temporary storage cavity is jointly formed by the panel body and the filter support.

[0039] Example 1:

[0040] like Figures 1 to 9 As shown, a suction-type steam brush with a detachable filter structure includes a housing 1, a panel assembly 2 installed at the front end of the housing 1, and a steam generating assembly 3 and a suction assembly 4 installed inside the housing 1. The housing 1 has a suction channel 11 communicating with the suction assembly 4. The panel assembly 2 includes a steam panel 21 and a suction panel 22. The suction panel 22 includes a panel body 221, a filter support 222 detachably connected to the panel body 221, and a filter 223 installed on the filter support 222. The panel body 221 is detachably connected to the housing 1. The filter support 222 is located on the rear side of the panel body 221. The panel body 221 has at least one suction port 224. The filter 223 is located between the suction port 224 and the suction channel 11, so that the suction port 224 and the suction channel 11 are connected through the filter 223. Figure 1 , Figure 5 and Figure 8In this context, the X direction represents the front-to-back direction, and the Z direction represents the up-to-down direction. In this application, the radial direction refers to the direction radiating outwards from the center of the panel assembly 2 within the front surface of the panel assembly 2.

[0041] For ease of understanding, some key terms in this embodiment are explained below.

[0042] The housing 1 is the main structure of the suction-type steam brush, used to house the various internal functional components and provide external support and protection. The housing 1 has an internal suction channel 11 that communicates with the suction assembly 4. The suction channel 11 can be an independent pipe structure or a specific space reserved inside the housing 1. Its shape and size can be designed according to the layout of the suction assembly 4 and the suction efficiency requirements, for example, it can be circular, square, or irregular in shape.

[0043] Panel assembly 2 is installed at the front end of housing 1 and is the part that contacts the surface to be cleaned with the suction-type steam brush. It integrates steam jetting and suction functions. Panel assembly 2 includes a steam panel 21 and a suction panel 22. The steam panel 21 and suction panel 22 can be two independent parts of panel assembly 2, combined together by means of snaps, screws, or adhesive to form a complete panel assembly 2, or each can be connected to housing 1 via a connecting structure. Alternatively, the steam panel 21 and suction panel 22 can also be an integrated structure of panel assembly 2, with each area divided to achieve its respective function.

[0044] The steam generating component 3 is installed inside the housing 1 and is responsible for heating water to generate high-temperature steam, which is then sprayed out through the steam panel 21 to soften and remove wrinkles from clothing or fabrics. The steam generating component 3 is a mature technology in the field and will not be described in detail here.

[0045] The suction assembly 4 is installed inside the housing 1 to generate suction. It draws hair, dust, and other debris from the surface of the clothing into the device through the suction channel 11 and the suction panel 22, and then blows them out of the housing 1 through the air outlet 12. The suction assembly 4 is a mature technology in the field and will not be described in detail here.

[0046] The suction channel 11 is a channel inside the housing 1 used to guide airflow. It is connected to the suction assembly 4 to ensure that the intake air and debris can be effectively transported. Except for its connection with the suction port 224 and the suction assembly 4, the suction channel 11 needs to be isolated and sealed from other components inside the housing 1.

[0047] The steam panel 21 is part of the panel assembly 2, and its surface is provided with steam nozzles 211 for guiding steam to be sprayed out evenly.

[0048] The suction panel 22 is another part of the panel assembly 2, and its surface is provided with a suction port 224 for adsorbing debris from the surface of clothing or fabric.

[0049] The panel body 221 is the main structural part of the suction panel 22, and it is provided with a suction port 224. The panel body 221 is detachably connected to the housing 1, which facilitates the user to clean blockages regularly. The detachable connection method includes common connection methods such as snap-fit, tight fit, magnetic fit, and screw connection. The suction port 224 can be a circular hole, or it can be a square, oval, or other geometrically shaped opening. There can be one or more suction ports 224, such as two, three or more, evenly distributed along its edge. The panel body 221 is preferably made of high-temperature resistant and corrosion-resistant engineering plastic, with certain thermal insulation and mechanical strength to ensure long-term stable operation in high-temperature steam environments.

[0050] The filter holder 222 is detachably connected to the panel body 221 to support and fix the filter 223. The detachable connection method includes common methods such as snap-fit, tight fit, magnetic fit, and screw connection. The filter holder 222 is located on the rear side of the panel body 221. This design allows the filter holder 222 to form a support structure inside the panel body 221 to support the filter 223.

[0051] The filter 223 is used to intercept inhaled hair, dust, and lint, preventing them from entering the suction channel 11 and suction assembly 4, thereby protecting internal components and maintaining suction efficiency. The filter 223 can be a separate mesh structure, such as made of wire mesh, fiber mesh, or a perforated plate, with pore sizes designed to intercept debris of specific sizes. The filter structure includes the filter support 222 and the filter 223, and can also be broadly considered as a component of the suction panel 22.

[0052] The air intake 224 is an opening on the panel body 221 for drawing in air and debris.

[0053] In the above technical solution, by detachably assembling the panel body 221 to the housing 1, and simultaneously placing the filter support 222 on the rear side of the panel body 221 and installing the filter 223 on the filter support 222, when performing routine cleaning and maintenance of the steam brush, it is only necessary to remove the panel body 221 from the housing 1 to simultaneously remove the filter support 222 and the filter 223. This achieves integrated disassembly, cleaning, and maintenance of the panel body 221, the filter support 222, and the filter 223, simplifying the cleaning operation process and effectively improving the convenience of user use and maintenance.

[0054] Specifically, in this application, the steam panel 21 is provided with at least one steam nozzle 211, which is connected to the steam generating component 3. The steam panel 21 is fixed to the housing 1 or the steam generating component 3. The housing 1 is provided with a handle 5 for holding, and the housing 1 is also provided with a water tank 6 for storing water, and a water pump 7 for transporting water from the water tank 6 to the steam generating component 3. The water pump 7 is sealed to the water tank 6 and the steam generating component 3 through pipelines to ensure stable and controllable water flow. After the steam generating component 3 heats the water into high-temperature and high-pressure steam, it is directionally sprayed out through the steam nozzle 211.

[0055] Specifically, the steam panel 21 serves as the interface between the suction-type steam brush and the item to be treated. It has at least one steam nozzle 211 for spraying steam generated by the steam generating assembly 3 onto the surface of the clothing. The number of steam nozzles 211 can be designed as one or more according to actual needs. For example, they can be evenly distributed along the circumference or radial direction of the steam panel 21 to achieve a wider or more concentrated steam coverage area. The shape of the steam nozzles 211 can be circular, elliptical, slit-shaped, etc., to adapt to different steam spray patterns, such as forming a fan-shaped steam flow or a diffused steam mist, thereby meeting the needs of different clothing materials and treatment requirements.

[0056] Meanwhile, the steam nozzle 211 and the steam generating assembly 3 are reliably connected via an internal channel or pipe. The steam generating assembly 3 is responsible for heating water and converting it into high-temperature steam, which is guided to the steam nozzle 211 through the connecting structure. This connecting structure is typically made of high-temperature resistant, pressure-resistant, and well-sealed materials to ensure that the steam does not leak during transportation and maintains stable pressure and temperature, thereby ensuring the continuity and effectiveness of steam injection.

[0057] Furthermore, the steam panel 21 is reliably fixed to the housing 1 or the steam generating assembly 3 via a connection method, such as screw fastening, snap-fit ​​engagement, welding, or bonding. In some embodiments, the steam panel 21 can be directly integrated with or tightly connected to the front end structure of the housing 1 to enhance the overall structural stability. In other embodiments, the steam panel 21 can also be directly fixedly connected to the steam outlet portion of the steam generating assembly 3 to form a compact steam output unit.

[0058] It is understood that, in one embodiment, such as Figure 6 and Figure 7 As shown, the panel body 221 has a ring structure and is arranged around the steam panel 21, with multiple air intakes 224 spaced around the steam panel 21. Correspondingly, the filter support 222 and the filter 223 are also arranged in a ring and are concentrically fitted with the panel body 221.

[0059] In the above technical solution, the panel body 221 is designed as a ring structure, the main purpose of which is to tightly and evenly surround the steam panel 21. This ring layout allows the suction function to form a continuous suction band around the core steam injection area of ​​the steam brush, thereby instantly and efficiently adsorbing debris softened or blown up by the steam while it is in action. Multiple suction ports 224 are evenly spaced along the circumference of the ring panel body 221, ensuring that the suction force is evenly distributed in all directions around the steam panel 21, avoiding suction blind spots or uneven suction force. The spacing can also be adjusted according to actual needs, including the number, size, and spacing of the suction ports 224, to adapt to different cleaning scenarios and adsorption requirements.

[0060] It is understood that, in another embodiment, the panel body is disposed on one side of the steam panel, and multiple air intakes are disposed on the panel body and located on one side of the steam panel. The filter support and filter are correspondingly disposed with respect to the panel body 221.

[0061] Preferably, the panel body 221 is detachably sleeved on the front end of the housing 1, the filter support 222 is detachably connected to the inner side of the panel body 221, the filter support 222 is located at the front end of the housing 1, and the front end of the housing 1 and the inner wall of the panel body 221 clamp the filter support 222 together.

[0062] Specifically, the circumferential inner side refers to the annular area enclosed by the inner wall of the panel body 221 along the circumferential direction. The filter support 222 is disposed within this annular area, with its outer edge tightly fitted to the inner wall of the panel body 221, and the filter support 222 is not directly exposed. The panel body 221 is installed at the front of the housing 1 in a fitting manner, providing better positioning and support. That is, the inner wall or inner structure of the panel body 221 matches the outer wall or outer structure of the housing 1, allowing the panel body 221 to cover or wrap the front end of the housing 1 from the outside. The filter support 222 is positioned in the internal circumferential space of the panel body 221, and its outer contour matches the inner contour of the panel body 221, allowing the filter support 222 to be constrained and positioned circumferentially by the panel body 221. The filter support 222 is located in the front end region of the housing 1 in the front-rear direction. When the panel body 221 is connected to the housing 1, the front end portion of the housing 1 (e.g., its edge or protrusion structure) will abut against the filter support 222 from the rear, while the inner wall of the panel body 221 (e.g., its internal flange or stepped structure) will abut against the filter support 222 from the front, thereby firmly fixing the filter support 222 between the housing 1 and the panel body 221.

[0063] In the above technical solution, when the panel body 221 is connected to the housing 1, the front end of the housing 1 and the inner wall of the panel body 221 can clamp the filter support 222 in the front-rear direction, so that the filter support 222 is firmly fixed between the panel body 221 and the housing 1. This effectively solves the problem of possible loosening or displacement of the filter support 222, thereby ensuring the stability of the filter 223 and the sealing of the air intake channel 11. Since the filter support 222 is clamped and fixed through the connection between the panel body 221 and the housing 1, the filter support 222 can also be released when the panel body 221 is disassembled, which facilitates the removal, cleaning or replacement of the filter 223 and improves the product's maintenance convenience. Furthermore, since the filter support 222 is located on the inner side of the panel body 221 and is not exposed, the filter support 222 will not fall off the housing 1 when the panel body 221 is assembled. This avoids the risk of the filter support 222 and the filter 223 accidentally falling off during use, and also avoids the situation where the filter support 222 is only removed and the cleaning is missed when the panel body 221 is disassembled due to misoperation.

[0064] It is understandable that, in one embodiment, such as Figures 1 to 4 As shown, the panel body 221 is provided with an elastic sheet 226 that can be elastically deformed in the radial direction. The inner wall of the elastic sheet 226 is provided with a first flange 2211. The outer wall of the front end of the housing 1 is provided with a first groove 13 that matches the first flange 2211. The panel body 221 and the housing 1 are detachably connected through the cooperation of the first flange 2211 and the first groove 13. The elastic sheet 226 is provided with a disassembly handle 227 that facilitates the operation of the elastic sheet 226 to deform it radially. The disassembly handle 227 is located on the lower side of the panel body 221.

[0065] In the above technical solution, the panel body 221 is installed on the front end of the housing 1 in a sleeve manner, forming an enclosing structure. When the panel body 221 is sleeved on the housing 1, the first flange 2211 can accurately engage in the first groove 13, thereby achieving a locked connection between the two. The panel body 221 integrates an elastic sheet 226 that can elastically deform in the radial direction. The elastic sheet 226 can elastically deform in the radial direction, meaning that its material and geometry allow it to elastically deform in the radial direction under the action of external force, that is, to bend outward, causing the first flange 2211 to disengage from the first groove 13. When no external force is applied, the elastic sheet 226 returns to its original shape by its own elasticity, allowing the first flange 2211 to re-engage in the first groove 13, ensuring a stable and reliable connection. During disassembly, by manipulating the elastic sheet 226 to deform radially, the first flange 2211 can be disengaged from the first groove 13, and the panel body 221 can be removed from the housing 1.

[0066] Preferably, the elastic sheet 226 is provided with a disassembly handle 227 for easy operation to cause radial deformation of the elastic sheet 226. The disassembly handle 227 is located on the lower side of the panel body 221. To facilitate user operation, the disassembly handle 227 on the elastic sheet 226 provides a point of force application, allowing the user to cause radial deformation of the elastic sheet 226 by pulling or pushing, thereby releasing the locked state. The disassembly handle 227 is typically located on the lower side of the panel body 221, making it less prone to accidental activation during product use and maintaining the overall simplicity of the product's appearance.

[0067] Preferably, the inner wall of the panel body 221 opposite to the elastic sheet 226 is provided with a second flange 2212, and the outer wall of the front end of the housing 1 is provided with a second groove 14 that engages with the second flange 2212.

[0068] In the above technical solution, the position opposite to the elastic piece 226 refers to the inner wall area opposite to the side of the panel body 221 where the elastic piece 226 is provided. That is, when the panel body 221 is assembled in place, this position is directly opposite to the radial side (such as the upper and lower sides or the left and right sides) of the elastic piece 226 in the circumferential direction of the housing 1, thereby forming a double-point positioning constraint in the circumferential direction. A second flange 2212 is added at the position opposite to the elastic piece 226 of the panel body 221, and a second groove 14 is provided on the outer wall of the front end of the housing 1 to engage with the second flange 2212. This realizes multi-point or symmetrical locking between the panel body 221 and the housing 1, enhances the connection stability between the panel assembly 2 and the housing 1, and effectively prevents the panel body 221 from shaking or accidentally falling off due to vibration or external force during use.

[0069] Understandably, in another embodiment, such as Figure 8 and Figure 9 As shown, the panel body 221 is tightly connected to the housing 1, and the lower side of the panel body 221 is provided with a protruding handle 228 for easy finger application.

[0070] In the above technical solution, the "protruding handle 228" refers to one or more protruding structures integrally formed or additionally provided on the lower side of the panel body 221. Its shape and size are designed to provide an ergonomic grip point, allowing users to easily grip and apply force with their fingers. The panel body 221 and the housing 1 are connected by a tight fit, ensuring the structural stability of the suction-type steam brush in operation. Simultaneously, the protruding handle on the lower side of the panel body 221 provides a clear and ergonomic operating point for the user. When cleaning or replacing the filter 223, the user can easily grasp the protruding handle and apply appropriate force to easily detach the tightly connected panel body 221 from the housing 1.

[0071] Example 2: This example further optimizes the structural layout based on Example 1.

[0072] Based on Example 1, such as Figure 3 , Figure 4 and Figure 9 As shown, a temporary storage cavity 225 is provided between the filter screen 223 and the air intake 224. The filter screen 223 covers the opening of the temporary storage cavity 225 near the air intake channel 11, and the side of the temporary storage cavity 225 near the air intake 224 is connected to the air intake 224. After the panel body 221 and the filter support 222 are disassembled, the opening of the temporary storage cavity 225 is set.

[0073] In the above technical solution, the temporary storage chamber 225 is a space located between the filter screen 223 and the air intake 224, used to temporarily collect and retain hair, dust, and lint intercepted by the filter screen 223. The temporary storage chamber 225 can be a simple groove structure, with sufficient depth and width to accommodate a certain amount of debris. By setting up the temporary storage chamber 225 and configuring the filter screen 223 between the temporary storage chamber 225 and the air intake channel 11, the above technical solution allows the inhaled hair, dust, and lint to first enter the temporary storage chamber 225 and be intercepted by the filter screen 223. This effectively extends the cleaning cycle of the filter screen 223, reduces the risk of direct clogging of the filter screen 223, and thus maintains the continuous suction efficiency of the suction-type steam brush. The opening of the temporary storage chamber 225 means that after the panel body 221 and the filter support 222 are disassembled, at least one side of the temporary storage chamber 225 is directly exposed to the external environment, allowing the user to visually inspect the accumulation of debris inside the temporary storage chamber 225. The above solution improves the ease of maintenance for the suction-type steam brush. Users can easily disassemble the relevant components to directly access and thoroughly clean the dust, hair, and other debris accumulated in the filter 223 and the temporary storage chamber 225, avoiding the decrease in suction efficiency and the generation of odors caused by long-term accumulation of debris.

[0074] Preferably, in this application, the cross-sectional area of ​​the temporary storage cavity 225 is greater than the cross-sectional area of ​​the air intake 224, and the total volume of all the temporary storage cavities 225 is greater than the total volume of all the air intakes 224.

[0075] Specifically, the cross-section of the air intake 224 refers to its projected area perpendicular to the airflow direction. When the cross-sectional area of ​​the air intake 224 is smaller than that of the temporary storage chamber 225, the airflow velocity entering the temporary storage chamber 225 will decrease due to the increased space. This reduction in air velocity helps larger or heavier particles to settle in the airflow deceleration zone, rather than directly impacting and adhering to the filter screen 223. This solution can effectively reduce the direct impact and clogging of the filter screen 223 by debris, thereby extending the service life and cleaning cycle of the filter screen 223. Simultaneously, when the total volume of all temporary storage chambers 225 is greater than the total volume of all air intakes 224, the temporary storage chambers 225 provide more space to accommodate the inhaled debris.

[0076] In the above technical solution, after the intake air and debris enter the temporary storage chamber 225, the airflow velocity is effectively reduced due to the increased cross-sectional area and volume. This allows the debris sufficient space and time to settle or buffer, preventing it from directly and quickly clogging the filter screen 223. This significantly improves the suction efficiency and stability of the suction-type steam brush, extends the cleaning cycle of the filter screen 223, reduces the frequency and difficulty of user maintenance, and thus enhances the user experience and convenience of the product.

[0077] In this application, when the suction-type steam brush is running, the water pump 7 pressurizes the clean water in the water tank 6 and delivers it to the steam generating component 3. The steam generating component 3 heats the clean water to vaporize it into high-temperature steam. The high-temperature steam is delivered to the steam panel 21 through the steam channel and sprayed out from the steam nozzle 211, thereby sterilizing the clothes at high temperature and removing wrinkles. At the same time, the suction component 4 also operates synchronously, relying on the motor to drive the fan to generate negative pressure, allowing the suction port 224 to draw in air. In this way, the clothes will adhere tightly to the surface of the steam panel 21 due to the negative pressure. The air drawn in by the suction port 224, along with the hair, dust, and other impurities it contains, is blocked by the filter screen 223 and accumulates slowly in the temporary storage chamber 225. The filtered air flows sequentially through the suction channel 11 and the suction component 4, and is finally blown out from the air outlet 12.

[0078] It is understood that, in one embodiment, such as Figure 9 As shown, the main body of the temporary storage cavity 225 is formed by the groove structure on the filter support 222. The filter 223 is located on the side of the temporary storage cavity 225 near the air intake channel 11, and the side of the temporary storage cavity 225 near the air intake 224 is connected to the air intake 224. In the above technical solution, the main body of the temporary storage cavity 225 is directly formed by the groove of the filter support 222 itself, without the need for additional independent cavity components. The structure is more compact and simple, and it is convenient for processing, assembly, and subsequent disassembly and cleaning.

[0079] It is understood that in another embodiment, the main body of the temporary storage cavity 225 is formed by the groove structure of the panel body 221, the filter screen 223 is located on the side of the temporary storage cavity 225 near the air intake channel 11, and the side of the temporary storage cavity 225 near the air intake 224 is connected to the air intake 224.

[0080] It is understood that, in another embodiment, such as Figure 3 As shown, the main body of the temporary storage cavity 225 is formed by the panel body 221 and the filter support 222. The filter 223 is located on the side of the temporary storage cavity 225 near the air intake channel 11, and the side of the temporary storage cavity 225 near the air intake 224 is connected to the air intake 224.

[0081] Example 3:

[0082] Based on Example 1, such as Figure 9 As shown, the filter screen 223 and the filter support 222 are integrally molded. This means that the filter screen 223 and the filter support 222 are manufactured as a single, inseparable unit. This integral molding structure eliminates the independent connection interfaces between the components, fundamentally avoiding the risk of the filter screen 223 loosening, shifting, or falling off due to vibration, impact, or water erosion during use or cleaning. This can be achieved through processes such as injection molding, compression molding, or 3D printing. For example, in injection molding, the mesh portion of the filter screen 223 and the frame portion of the filter support 222 can be formed in one injection molding process, eliminating the independent connection interfaces between them and ensuring a high degree of structural integration and stability. This solution fundamentally eliminates the risk of loosening or falling off that may exist in traditional assembly methods.

[0083] Example 4:

[0084] Based on Embodiment 1, the filter screen 223 is fixed to the filter screen support 222. Fixing the filter screen 223 to the filter screen support 222 means that the filter screen 223 is securely connected to the filter screen support 222 in a non-removable manner. The fixing method may include, but is not limited to, ultrasonic welding, hot-melt riveting, bonding, riveting, or mechanical pressing. For example, the edge of the filter screen 223 can be welded together with the corresponding groove of the filter screen support 222 using ultrasonic welding to form a strong connection. Alternatively, a special adhesive can be used to adhere the filter screen 223 to the support surface of the filter screen support 222. These fixing methods are designed to provide stronger connection strength and stability than simple installation, preventing the filter screen 223 from accidentally detaching during use.

[0085] In the above technical solution, the filter screen 223 is firmly fixed to the filter screen bracket 222, enhancing the connection strength and stability between the filter screen 223 and the filter screen bracket 222. Similarly, fixing the filter screen 223 to the filter screen bracket 222 by welding, bonding, or other methods also provides a reliable connection, ensuring that the filter screen 223 always remains in the preset position. This ensures that the filtration function between the air intake 224 and the air intake channel 11 remains effective, preventing hair, dust, and other debris from entering the air intake channel 11 and causing blockage or damage to the air intake assembly 4, thereby extending the service life of the suction-type steam brush and improving the overall reliability of the product and the user experience.

[0086] Example 5:

[0087] Based on Embodiment 1, the filter screen 223 is detachably connected to the filter screen support 222. "Detachable connection" means that the filter screen 223 can be easily separated from and reinstalled from the filter screen support 222 without damaging the components. This detachable connection can be implemented using various structures. For example, the edge of the filter screen 223 can be designed with a snap-fit ​​structure that engages with a corresponding slot on the filter screen support 222, allowing for engagement and disengagement by pressing or slight bending. Alternatively, the filter screen 223 can be slidably inserted into or withdrawn from the guide groove of the filter screen support 222 in a specific direction. Furthermore, magnetic attraction can be used, with magnetic elements on both the filter screen 223 and the filter screen support 222, utilizing magnetic force for adsorption and separation. These connection methods all aim to provide a solution for quickly disassembling and installing the filter screen 223 without tools.

[0088] In the above technical solution, when the filter screen 223 becomes clogged due to the adsorption of impurities, the user can directly separate the filter screen 223 for individual cleaning or replacement when removing the panel body 221, filter screen bracket 222 and filter screen 223 from the housing 1. The cleaning is more thorough and the replacement cost is lower. In addition, the filter screen 223 does not need to be fixed to the filter screen bracket 222 in advance, which simplifies the manufacturing process and reduces the production cost.

[0089] Example 6:

[0090] Based on Embodiment 1, the filter screen 223 and the filter screen support 222 are separate structures, and the filter screen 223 is clamped between the panel body 221 and the filter screen support 222 when they are connected.

[0091] In the above technical solution, the filter screen 223 is designed to be separate from the filter screen support 222, and is clamped and fixed when the panel body 221 is connected to the filter screen support 222. This ensures the stability of the filter screen 223 during the operation of the suction-type steam brush, preventing it from shifting or falling off, thereby ensuring the normal operation of the suction assembly 4 and the cleanliness of the suction channel 11. At the same time, when the filter screen 223 becomes clogged due to adsorbed debris, the user can directly separate the filter screen 223 for individual cleaning or replacement when removing the panel body 221, filter screen support 222, and filter screen 223 from the housing 1. This results in more thorough cleaning, lower replacement costs, and the filter screen 223 does not need to be fixed to the filter screen support 222 beforehand, simplifying the manufacturing process and reducing production costs.

[0092] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
