Description

Technical Field

[0001] This utility model relates to the field of household cleaning appliances technology, and in particular to an adsorption-type handheld steam brush with a built-in filter. Background Technology

[0002] Handheld steam brushes are a highly efficient household cleaning tool that uses high-temperature steam to soften and dissolve stains, dust, and bacteria on the surface of fabrics. They are popular with consumers because they are environmentally friendly, disinfectant, and require no chemical cleaners.

[0003] However, when traditional handheld steam brushes dissolve and remove stains during the cleaning process, these liquid or solid residues containing dirt usually remain on or around the fabric surface. Users need to wait for them to air dry naturally or use additional vacuum cleaners, rags, etc. for secondary cleaning. This not only causes inconvenience and interruption to the cleaning process, but may also cause the dried stains to re-adhere, forming "secondary pollution" and affecting the final cleaning effect.

[0004] Therefore, the market urgently needs a handheld steam cleaning device that can instantly absorb cleaning residues, has an easy-to-disassemble and clean filter element, and has a compact and lightweight overall structure. Utility Model Content

[0005] The purpose of this invention is to provide an adsorption-type handheld steam brush with a built-in filter element, which can instantly adsorb cleaning residues, and the filter element is easy to disassemble and clean, with a compact and lightweight overall structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adsorption-type handheld steam brush with a built-in filter element, comprising a housing, a steam generating component and an exhaust fan disposed inside the housing, and an adsorption component detachably connected to the housing, the housing being provided with a mounting base for accommodating the adsorption component, one end of the adsorption component being provided with an air intake, the other end being connected to the exhaust fan, and an air intake channel being formed inside the adsorption component, wherein a filter element component is disposed inside the air intake channel.

[0007] By adopting the above technical solution, the steam generating component, exhaust fan, and adsorption component are integrated into one unit, making the device compact and lightweight, suitable for handheld operation. It simultaneously achieves dual functions of steam and adsorption. While the steam dissolves and removes stains, the air intake can immediately suck in residual moisture, dust, lint, and other contaminants containing dirt, effectively avoiding secondary residue and contamination, and improving the efficiency and thoroughness of a single cleaning. On the other hand, the adsorption component adsorbs clothing onto the brush head surface, enabling one-handed ironing operation and optimizing the user experience. In addition, the adsorption component is detachable, making it convenient for users to maintain and clean the filter element, extending the product's service life.

[0008] A further feature of this invention is that the filter element assembly includes a support frame, a filter screen and a filter element located on the support frame, the support frame having an opening communicating with the airflow of the exhaust fan, the opening forming the air outlet of the air intake channel, the filter screen and the filter element being disposed at the opening and covering the opening, a hollow connector being sealed on the mounting base, the hollow connector being sealed to the opening, a hollow cover for accommodating the filter element being mated to the hollow connector, and the filter element sealingly abutting against the hollow connector through the opening.

[0009] By adopting the above technical solution, particulate matter in the air can be effectively filtered, preventing pollutants from entering the exhaust fan.

[0010] A further feature of this invention is that the support frame extends toward the interior of the mounting base and forms the hollow cover, the filter screen is circumferentially disposed outside the hollow cover, the filter element assembly further includes a support plate that abuts against the filter screen, and the hollow cover is snapped into the support plate.

[0011] By adopting the above technical solution, when the hollow cover is fixed to the support plate, the filter screen will not fall off due to shaking.

[0012] A further feature of this invention is that the mounting base is L-shaped and includes a guide portion and an air duct docking portion. A plug is protruding on the end face of the air duct docking portion corresponding to the opening. A slot is provided on the support frame corresponding to the position of the plug, and the plug is inserted into the slot.

[0013] By adopting the above technical solution, precise positioning of the support frame and the mounting base can be achieved.

[0014] A further feature of this invention is that the guide portion is provided with a guide protrusion, one end of which has a recessed hole, and the end face of the adsorption component is provided with a guide groove corresponding to the position of the guide protrusion. A pin corresponding to the position of the recessed hole is provided on the guide groove. The guide protrusion and the guide groove guide and cooperate, and the pin engages with the recessed hole.

[0015] By adopting the above technical solution, the guide protrusion and guide groove cooperate to guide the user to correctly install the adsorption component, reduce the difficulty of operation, and improve the user experience. After the adsorption component is fully inserted into the mounting base along the guide protrusion, the pin and the concave hole are engaged, which not only improves the stability of the connection between the adsorption component and the mounting base, but also enhances the operation feel and further strengthens the positioning and fixing effect.

[0016] A further feature of this invention is that the guide portion and the air duct connection portion are respectively provided with a buckle groove, and the adsorption component is provided with a buckle corresponding to the position of the buckle groove, and the buckle engages with the buckle groove.

[0017] By adopting the above technical solution, the adsorption component slides forward along the width of the guide section under the guidance of the guide protrusion and the guide groove until the buckle engages with the buckle groove and a "click" sound is heard, forming a dual feedback of touch and hearing. By touch, it can be confirmed whether the adsorption component has accurately and reliably entered the predetermined position, which improves the intuitiveness and humanization of the operation and further enhances the positioning and fixing effect.

[0018] A further feature of this invention is that the opening is sealed with a hollow connector, one end of which extends to abut against the filter element and the other end extends to the output end of the exhaust fan. The hollow connector has a notch, and the mounting base has a protrusion corresponding to the position of the notch, which engages with the notch.

[0019] By adopting the above technical solutions, the airtightness of the air intake channel is ensured, air leakage is prevented, and the adsorption efficiency of the exhaust fan is improved.

[0020] A further feature of this invention is that the impeller of the exhaust fan is covered with a ventilation bracket, the housing has an air outlet corresponding to the position of the ventilation bracket, the ventilation bracket has an air inlet that is sealed and connected to the hollow connector, and an air outlet corresponding to the position of the air outlet.

[0021] By adopting the above technical solution, the impeller is covered by a ventilation bracket, which guides the airflow from the air inlet to the air outlet, reduces turbulence, improves the working efficiency of the exhaust fan, and prevents foreign objects from contacting the impeller, thus extending the life of the exhaust fan.

[0022] A further feature of this invention is that a steam panel coplanar with the air inlet is connected to the housing, an open opening is provided on the housing, the mounting base is placed in the open opening and adjacent to the steam panel, and the adsorption component is connected to the mounting base and connected to the outline of the steam panel and the housing.

[0023] By adopting the above technical solution, the adsorption component is installed smoothly on the surface of the housing, improving handheld comfort and aesthetics. In addition, the adsorption component and the steam generator are independent of each other, ensuring that the steam function and adsorption function are separated, avoiding mutual interference, and facilitating maintenance and repair.

[0024] In summary, this utility model has the following beneficial effects: The device employs a detachable adsorption component connected to the housing. A mounting base for the adsorption component is located on the housing. One end of the adsorption component has an air intake, and the other end connects to an exhaust fan, forming an air intake channel inside the adsorption component. A filter element is located within this air intake channel. This design integrates the steam generator, exhaust fan, and adsorption component into a single unit, making the device compact, lightweight, and suitable for handheld operation. It simultaneously achieves both steam and adsorption functions. While the steam dissolves and removes stains, the air intake immediately draws in moisture, dust, lint, and other residues containing dirt, effectively preventing secondary residue and contamination, thus improving the efficiency and thoroughness of each cleaning cycle. Furthermore, the adsorption component adheres clothing to the brush head surface, enabling one-handed ironing and optimizing the user experience. The detachable adsorption component facilitates maintenance and cleaning of the filter element, extending the product's lifespan. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] An adsorption-type handheld steam brush with a built-in filter, such as Figure 1-8 As shown, the device includes a housing 1, within which a steam generating assembly 2 and an exhaust fan 3 are installed. The steam generating assembly 2 is a device such as a water tank, boiler, or water pump used to generate steam. Using the above-mentioned components to generate steam is a conventional technical means, which will not be described in detail here. The device also includes an adsorption assembly 4 detachably connected to the housing 1. The housing 1 is provided with a mounting base 11 for accommodating the adsorption assembly 4. The mounting base 11 is fixedly connected to the housing 1 by bolts, and the adsorption assembly 4 is slidably connected to the mounting base 11. One end of the adsorption assembly 4 is provided with an air intake 401, and the other end is connected to the exhaust fan 3. An air intake channel 402 is formed inside the adsorption assembly 4, and a filter element assembly is provided inside the adsorption assembly 4 located in the air intake channel 402. Through the above structure, on the one hand, the steam generating component 2, the exhaust fan 3, and the adsorption component 4 are integrated into one unit, making the device compact and lightweight, suitable for handheld operation. It simultaneously achieves dual functions of steam and adsorption. Moreover, while the steam dissolves and removes stains, the air intake 401 can immediately suck in residual moisture, dust, lint, and other contaminants containing dirt, effectively avoiding secondary residue and contamination, and improving the efficiency and thoroughness of a single cleaning. On the other hand, the adsorption component 4 adsorbs clothing onto the brush head surface, thereby enabling one-handed ironing operation and optimizing the user experience. In addition, the adsorption component 4 is detachable, making it convenient for users to maintain and clean the filter element, extending the product's service life.

[0036] Preferably, the filter assembly includes a support frame 51, and a filter screen 52 and a filter element 53 located on the support frame 51. The filter screen 52 and the filter element 53 are located at the end away from the exhaust fan 3. The support frame 51 has an opening 510 that communicates with the airflow of the exhaust fan 3. The filter element 53 can be cleaned and replaced through the opening 510. The opening 510 forms the air outlet of the air intake channel 402, ensuring that the air intake channel 402 is unobstructed. The filter screen 52 and the filter element 53 are disposed at the opening 510. Covering the opening 510 effectively filters airborne particles, preventing pollutants from entering the exhaust fan 3. A hollow connector 6 is sealed on the mounting base 11, and the hollow connector 6 is sealed to the opening 510. A sealing ring is circumferentially arranged on the hollow connector 6, and the hollow connector 6 is sealed to the opening 510 through the sealing ring. A hollow cover 511 accommodating the filter element 53 is mated to the hollow connector 6, and the filter element 53 is sealed against the hollow connector 6 through the opening 510. Through this design, all air in the suction channel 402 must be filtered through the filter element assembly before being discharged.

[0037] Preferably, the support frame 51 extends toward the interior of the mounting base 11 and forms the hollow cover 511. The filter screen 52 is circumferentially disposed outside the hollow cover 511. The filter element assembly also includes a support plate 54 that abuts against the filter screen 52. The hollow cover 511 extends toward the support plate 54 and forms a snap-fit ​​structure with the support plate 54. When the hollow cover 511 is snap-fitted and fixed with the support plate 54, the filter screen 52 will not fall off due to shaking.

[0038] Preferably, the mounting base 11 is L-shaped, including a horizontally arranged guide portion 111 and a vertically arranged air duct docking portion 112. The guide portion 111 and the air duct docking portion 112 are integrally formed. An insertion block 1121 is protruding on the end face of the air duct docking portion 112 corresponding to the opening 510. A slot 512 corresponding to the position of the insertion block 1121 is opened on the support frame 51. The adsorption component 4 slides and connects with the mounting base 11 along the width direction of the guide portion 111, so that the insertion block 1121 and the slot 512 are inserted into each other, thereby achieving precise positioning.

[0039] Preferably, the guide portion 111 is provided with a guide protrusion 1111, which extends along the width direction of the guide portion 111. A recessed hole 1112 is formed at one end of the guide protrusion 1111 near the steam panel 8. A guide groove 41 corresponding to the position of the guide protrusion 1111 is formed on the end face of the adsorption assembly 4. A pin 411 corresponding to the position of the recessed hole 1112 is provided on the guide groove 41. The guide protrusion 1111 guides and engages with the guide groove 41, and the pin 411 engages with the recessed hole 1112. Through the above structural design, the guide protrusion 1111 and the guide groove 41 guide and engage, guiding the user to correctly install the adsorption assembly 4, reducing operational difficulty and improving user experience. After the adsorption assembly 4 is fully inserted into the mounting base 11 along the guide protrusion 1111, the pin 411 engages with the recessed hole 1112, which not only improves the stability of the connection between the adsorption assembly 4 and the mounting base 11, but also enhances the operating feel and further strengthens the positioning and fixing effect.

[0040] Preferably, the guide portion 111 and the air duct docking portion 112 are respectively provided with a locking groove 110. The locking groove 110 on the guide portion 111 is located at the center of the guide portion 111, and there are two locking grooves 110 on the air duct docking portion 112, which are located on both sides of the air duct docking portion 112. The adsorption component 4 on the guide portion 111 is provided with a buckle 42 corresponding to the position and number of the locking grooves 110. The buckle 42 engages with the locking grooves 110. Through the above structural design, the adsorption component 4 slides forward along the width direction of the guide portion 111 under the guidance of the guide protrusion 1111 and the guide groove 41 until the buckle 42 engages with the locking groove 110 and a "click" sound is heard, forming a dual feedback of touch and hearing. It can be confirmed by touch whether the adsorption component 4 has accurately and reliably entered the predetermined position, which improves the intuitiveness and user-friendliness of the operation and further enhances the positioning and fixing effect.

[0041] Preferably, the opening 510 is sealed with a hollow connector 6. One end of the hollow connector 6 extends to abut against the filter element 53, and the other end extends to the output end of the exhaust fan 3. When the adsorption assembly 4 is connected to the mounting base 11, the opening 510 of the support frame 51 is sealed with the hollow connector 6. The hollow connector 6 is provided with a notch 61, and the mounting base 11 is provided with a protrusion 113 corresponding to the position of the notch 61. When the hollow connector 6 is sealed with the opening 510, the protrusion 113 engages with the notch 61, thus fixing the hollow connector 6 to the mounting base 11 and enhancing the reliability of the connection between the hollow connector 6 and the mounting base 11. Through the above design, the airtightness of the suction channel 402 is ensured, preventing air leakage and improving the adsorption efficiency of the exhaust fan 3.

[0042] Preferably, the impeller of the exhaust fan 3 is covered by a ventilation bracket 7, which is fixed to the mounting base 11 by bolts. The housing 1 has an air outlet 12 corresponding to the position of the ventilation bracket 7. The ventilation bracket 7 has an air inlet 71 sealed to the hollow connector 6 and an air outlet 72 corresponding to the position of the air outlet 12. Air discharged through the air inlet channel enters the ventilation bracket 7 through the hollow connector 6, moving axially along the exhaust fan 3 and then exiting through the air outlet 72 towards the air outlet 12. The air then exits radially along the exhaust fan 3. By covering the impeller with the ventilation bracket 7, the airflow is guided from the air inlet 71 to the air outlet 72, reducing turbulence, improving the working efficiency of the exhaust fan 3, and preventing foreign objects from contacting the impeller, thus extending the lifespan of the exhaust fan 3.

[0043] Preferably, the housing 1 is further connected to a steam panel 8 coplanar with the air intake 401. The steam panel 8 is securely connected to the housing 1. The steam panel 8 has a recess 81, through which steam holes 82 are opened, and the steam holes 82 are spaced apart from the steam panel 8. The outer contours of the steam panel 8 and the air intake 401 fit together and are located on the same horizontal plane. When the clothes to be ironed are attracted to the air intake 401 by the adsorption component 4, the steam holes 82 on the steam panel 8 are exposed due to the presence of the recess 81. The steam brush will not be blocked by clothing, allowing for ventilation and ensuring normal operation of the ironing function. An open opening is provided on the housing 1, and the mounting base 11 is placed within this opening, adjacent to the steam panel 8. The adsorption component connects to the mounting base 11 and is integrated with the outline of the steam panel 8 and the housing 1. The guide portion 111 of the mounting base 11 has its two opposite sides contacting the housing 1, and the side of the guide portion 111 opposite to the air duct connection portion 112 contacts the steam panel 8. This structural design ensures that the adsorption component 4 is smoothly flush with the surface of the housing 1 after installation, improving hand comfort and aesthetics. Furthermore, it ensures that the adsorption component 4 and the steam generator are independent, separating the steam and adsorption functions to avoid mutual interference and facilitating maintenance.

[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
