DETAILED DESCRIPTION

[0041] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] Example

[0045] See also Figures 1 to 11 , the present invention discloses a multifunctional cleaning device, comprising a steam brush head 1 and a roller brush device 2 detachably connected to the steam brush head 1;

[0046] The roller brush device 2 includes a support 21 and a roller brush cleaning assembly arranged on the support 21, wherein a cleaning port 2101 for removing dirt from the roller brush cleaning assembly is provided on the cleaning contact surface of the support 21; a connecting groove 2106 is provided on the support 21, and the connecting groove 2106 penetrates the cleaning contact surface, and the steam brush head 1 is plugged into the connecting groove 2106 and the steam outlet of the steam brush head 1 faces the cleaning contact surface, so that the steam of the steam brush head 1 is sprayed toward one side of the cleaning contact surface;

[0047] The cleaning contact surface is the side of the support 21 that contacts the surface to be cleaned.

[0048] Thus, by detachably connecting the steam brush head 1 and the roller brush device 2, the roller brush device 2 and the steam brush head 1 can be used independently. After the two are assembled, the steam from the steam brush head 1 in the cleaning device is sprayed toward one side of the cleaning contact surface, thereby achieving ironing of clothes and softening dirt, making it easy for the dirt to separate from the surface of the clothes to be cleaned. The dirt is cleaned by the roller brush cleaning assembly and is stored in the support 21 through the cleaning port 2101, thereby achieving cleaning of dirt on the surface of the clothes, such as animal hair, etc., with good cleaning effect, achieving diversification of product functions, and facilitating daily maintenance.

[0049] Preferably, the roller brush cleaning assembly comprises a roller brush 22 disposed on a support 21, a driving member, a negative pressure generating device 24 and a collecting box 25, and the roller brush 22 is rotatably disposed on the support 21;

[0050] The rotating driving member 23 is connected to the roller brush 22 and is used to drive the roller brush 22 to rotate;

[0051] The negative pressure generating device 24 is used to generate negative pressure to suck dirt from the surface to be cleaned and collect it in the collection box 25 .

[0052] See also Figure 2 , Figure 4 In some possible implementations, a limiting convex edge 21061 is provided on the inner side of the connecting groove 2106 to abut against the end surface of the steam brush head 1.

[0053] Thus, the steam brush head 1 is inserted into the connecting groove 2106 , and then the steam brush head 1 is limited by the limiting convex edge 21061 to prevent the steam brush head 1 from passing through the connecting groove 2106 and being separated from the support 21 .

[0054] See also Figure 2 In some possible implementations, further, a buffer gasket 3 is embedded on one side of the limiting convex edge 21061 facing the steam brush head 1.

[0055] By providing the buffer gasket 3 , the connection between the steam brush and the support 21 can be buffered, so as to avoid excessive impact on the support 21 after the steam brush is inserted into the support 21 , thereby preventing the support 21 or the steam brush head 1 from being damaged.

[0056] See also Figure 2 In some possible implementation manners, a snap connector 4 is movably provided on one of the support 21 and the steam brush head 1 , and a groove 5 cooperating with the snap connector 4 is provided on the other.

[0057] The support 21 is connected to the steam brush head 1 by the cooperation between the snap connector 4 and the groove 5, which is convenient and quick.

[0058] See also Figure 2 In some possible implementations, the groove 5 is formed on the outer surface of the steam brush head 1, the snap connector 4 is pivotally connected to the support 21, and the support 21 is provided with a connecting hole 2108 connected to the connecting groove 2106, and the snap connector 4 can be snapped and fixed to the groove 5 through the connecting hole 2108.

[0059] In some possible implementations, the snap connector 4 is further connected to an elastic member (not shown in the figure), and the elastic member applies elastic force to the snap connector 4 to increase the pressure between the snap connector 4 and the groove 5 .

[0060] See also Figure 4 , Figure 6For example, the elastic member can be a torsion spring, which is coaxially arranged with the snap connector 4. The torsion spring applies a torque to the snap connector 4 to make it swing toward one side of the connecting hole 2108. Under normal circumstances, the snap connector 4 can pass through the connecting hole 2108 and pass out of the connecting groove 2106. The torque applied by the torsion spring to the snap connector 4 can make the connection between the snap connector 4 and the groove 5 tighter, thereby avoiding looseness between the roller brush device 2 and the steam brush head 1.

[0061] See also Figure 1 In some possible implementation manners, the support 21 is provided with at least one tip 2107 , and the steam brush head 1 is disposed near the tip 2107 .

[0062] Therefore, it is possible to iron the hard-to-iron corners such as the collar of clothing, thus improving the applicability of the product.

[0063] See also Figure 1 , illustratively, the support 21 is provided with a tip 2107, and the overall structure is a combination of a triangle and a rectangle.

[0064] See also Figure 2 In some possible implementations, the roller brush 22 is disposed on a side of the connecting groove 2106 that is away from the tip 2107 .

[0065] Such an arrangement enables the center of the roller brush device 2 to be closer to the center of the handle of the steam brush head 1, so that the center of gravity of the overall structure of the cleaning device is stable and easy to take and put.

[0066] See also Figure 4 In some possible implementations, the negative pressure generating device 24 includes a negative pressure wind wheel, and the negative pressure wind wheel is driven by a rotating driving member 23.

[0067] Therefore, a rotating driving member 23 can be used to simultaneously drive the negative pressure wind wheel and the roller brush 22 to rotate, thereby performing negative pressure suction while the roller brush 22 is running, which is beneficial to simplifying the structure and reducing the overall volume of the product.

[0068] See also Figure 4 , Figure 7 In some possible implementations, the rotating driving member 23 is a motor with a dual output shaft, the axis of the roller brush 22 is arranged parallel to the main shaft axis of the motor, one end of the motor is drivingly connected to the roller brush 22, and the output shaft at the other end is coaxially fixed with the negative pressure wind wheel, and the airflow generated by the negative pressure wind wheel passes through the motor and is discharged from the support 21.

[0069] Of course, in some possible implementations, the rotating drive member 23 may be an ordinary drive motor, which drives the roller brush 22 to rotate; the negative pressure generating device 24 also includes a wind generating motor (not shown in the figure) arranged corresponding to the negative pressure wind wheel, and the wind generating motor independently drives the negative pressure wind wheel to rotate to generate negative pressure.

[0070] As a result, the arrangement structure of the roller brush 22, the motor and the negative pressure fan is compact, and the airflow generated by the negative pressure fan passes through the motor and is discharged from the support 21, thereby cooling the motor, extending the working time of the motor, and protecting the motor and extending its service life.

[0071] See also Figure 1 , Figure 8 In some possible implementations, a roller brush cavity 2102 for installing a roller brush 22 is provided in the support 21; the roller brush 22 is rotatably disposed in the roller brush cavity 2102, and its rotation axis is parallel to the surface of the support 21 that contacts the surface to be cleaned, and the roller brush 22 at least partially protrudes from the support 21 and is exposed outside the cleaning port 2101; the collecting box 25 is connected to the cleaning port 2101 and the negative pressure generating device 24.

[0072] Therefore, the axis of the roller brush 22 is set parallel to the contact surface, and the roller brush 22 is driven to rotate by the rotating driving member 23. The rotation of the roller brush 22 beats the dirt on the surface to be cleaned, loosening it and making it easy to separate from the surface to be cleaned, and then the negative pressure generating device 24 generates negative pressure suction, and the dirt is adsorbed from the surface to be cleaned through the cleaning port 2101 and stored in the collection box 25, thereby improving the cleaning effect.

[0073] See also Figure 4 , Figure 7 In some possible implementations, the roller brush device 2 further includes a battery 26 , and the battery 26 is electrically connected to the rotating drive member 23 .

[0074] Therefore, the rotating driving member 23 is powered by the battery 26, which reduces the trouble of pulling wires, thereby achieving the portability of the roller brush device 2 and the convenience of position conversion.

[0075] See also Figure 3 , Figure 4 , Figure 8 , Fig. 9 In some possible implementations, a locking piece 27 is provided at least at one end of the roller brush 22, and the roller brush 22 can rotate relative to the locking piece 27; a mounting hole 2103 connected to the roller brush cavity 2102 is provided on the side wall of the support 21, and the roller brush 22 passes through the mounting hole 2103 from the outside to the inside to be installed in the roller brush cavity 2102, and the locking piece 27 is detachably connected to the mounting hole 2103.

[0076] Thus, the roller brush 22 can be installed in the roller brush cavity 2102 from the outside to the inside of the mounting hole 2103, so that the roller brush 22 is installed on the support 21, and is fixed to the mounting hole 2103 by the locking piece 27, so that the roller brush 22 is locked to the support 21; when disassembling, the locking piece 27 is removed from the mounting hole 2103, and the roller brush 22 can be taken out of the mounting hole 2103, that is, the roller brush 22 is removed from the support 21, and then the roller brush 22 can be cleaned, maintained or replaced, and the disassembly and assembly are simple, and the maintenance of the roller brush 22 is convenient and quick.

[0077] See also Figure 4 , Figure 8 In some possible implementations, a locking member 27 is disposed at one end of the roller brush 22 , and the other end thereof is rotatable relative to the support 21 and can be separated from the support 21 .

[0078] Therefore, as a possible implementation mode, one end of the roller brush 22 can be detachably connected to the support 21, while the other end is detachably connected to the mounting hole 2103 by a locking piece 27, so that in the process of detaching the roller brush 22 from the support 21, one end of the roller brush 22 only needs to be separated from the support 21, and the locking piece 27 can be detached from the support 21 together with the roller brush 22; during installation, only one end of the roller brush 22 needs to be connected to the support 21, and the other end needs to be locked with the mounting hole 2103 by the locking piece 27, thereby improving the convenience of disassembly and assembly of the roller brush 22.

[0079] See also Figure 8 In some possible implementations, a first connecting component 28 is further included, wherein the first connecting component 28 includes a first pin 2801 and a first insertion groove 2802 that is plugged into and cooperates with the first pin 2801, wherein the first pin 2801 is rotatably set on the support 21, and the first insertion groove 2802 is set on the roller brush 22.

[0080] Thus, the roller brush 22 and the support 21 are separable through the cooperation of the first pin 2801 and the first plug-in groove 2802, and since the first pin 2801 is rotatably connected to the roller brush 22 or the support 21, after the first pin 2801 and the first plug-in groove 2802 cooperate, the roller brush 22 and the support 21 are connected, and relative rotation between the two can be achieved, thereby simplifying the installation structure.

[0081] Of course, inspired by the present application, those skilled in the art may also use other detachable structures in the prior art to connect the roller brush 22 to the support 21 , for example, the roller brush 22 and the support 21 are connected by magnetic adsorption.

[0082] See also Figure 7 , Figure 8 In some possible implementations, the first pin 2801 is connected to the rotating driving member 23 via a transmission assembly 29 .

[0083] Thus, the power is transmitted from the rotating driving member 23 to the first pin 2801 through the transmission assembly 29 to drive the first pin 2801 to rotate, thereby driving the roller brush 22 connected to the first pin 2801 to rotate.

[0084] See also Figure 7 In some possible implementations, the transmission assembly 29 includes a first synchronous pulley 2901 connected to the first pin 2801, a second synchronous pulley 2902 connected to the rotating driving member 23, and a synchronous belt 2903 connecting the first synchronous pulley 2901 and the second synchronous pulley 2902.

[0085] Thus, the power of the second synchronous pulley 2902 is transmitted to the first synchronous pulley 2901 through the synchronous belt 2903 , thereby realizing the rotation drive of the roller brush 22 by the rotating driving member 23 .

[0086] In other possible implementations, the first synchronous pulley 2901 , the second synchronous pulley 2902 , and the synchronous belt 2903 may be replaced by a sprocket chain assembly.

[0087] Of course, in other possible ways, a gear assembly or other transmission methods in the prior art can also be used as the transmission assembly 29 .

[0088] See also Figure 8 In some possible implementation modes, in some possible implementation modes, a first rotating groove 210 is provided on one of the locking member 27 and the roller brush 22, a first rotating member 211 is rotatably provided in the first rotating groove 210, and the other of the locking member 27 and the roller brush 22 is connected to the first rotating member 211.

[0089] In some possible implementations, the first rotating member 211 may be a ball or a roller, or the first rotating member 211 may be a bearing.

[0090] In some possible implementations, the first rotating groove 210 is disposed on the locking member 27 , the first rotating member 211 is rotationally matched with the first rotating groove 210 , and the first rotating member 211 is connected to the roller brush 22 , thereby achieving relative rotation between the locking member 27 and the roller brush 22 .

[0091] See also Figure 8 In some possible implementations, when the first rotating member 211 is rotatably disposed on the roller brush 22, a first connecting shaft 212 is disposed on the locking member 27, and a first connecting hole 21101 for connecting the first connecting shaft 212 is disposed on the first rotating member 211, thereby realizing a rotatable connection between the roller brush 22 and the locking member 27.

[0092] Of course, when the first rotating member 211 is arranged on the locking member 27 , the first connecting shaft 212 is correspondingly arranged on the roller brush 22 .

[0093] In some possible implementations, the first connection hole 21101 may be a through hole or a blind hole.

[0094] Similarly, see Figure 8 In order to realize the rotational connection between the support 21 and the first pin 2801, in some possible implementation methods, a second rotation groove 213 is provided on one of the support 21 and the first pin 2801, a second rotation member 214 is rotatably provided in the second rotation groove 213, and the other one of the support 21 and the first pin 2801 is connected to the second rotation member 214.

[0095] For example, the second rotation groove 213 is disposed on the support 21 , and a second connecting shaft 215 connected to the second rotating member 214 is fixedly disposed in the first pin 2801 .

[0096] See also Fig. 9 In some possible implementations, a locking member 27 is respectively provided at both ends of the roller brush 22, and a mounting hole 2103 is provided on the support 21 corresponding to each locking member 27, and the locking member 27 and the roller brush 22 are detachably connected.

[0097] Thus, the roller brush 22 can be removed from either end of the roller brush 22 , further improving the convenience of maintenance.

[0098] See also Fig. 9 In some possible embodiments, the roller brush device 2 also includes a second connecting component 218, wherein the second connecting component 218 includes a second pin 21801 and a second plug-in groove 21802 that is plugged into and cooperates with the second pin 21801, wherein the second pin 21801 is rotatably disposed on any one of the roller brush 22 and the locking member 27, and the second plug-in groove 21802 is disposed on the other of the roller brush 22 and the locking member 27.

[0099] Therefore, through the cooperation between the second pin 21801 and the second insertion groove 21802, the locking member 27 and the roller brush 22 can be separated.

[0100] For example, see Fig. 9 The second pin 21801 is rotatably disposed on the locking member 27, and the second insertion groove 21802 is disposed at the end of the roller brush 22. Through the cooperation of the second pin 21801 and the second insertion groove 21802, the detachable connection between the locking member 27 and the roller brush 22 is achieved.

[0101] Of course, inspired by the present application, those skilled in the art may also use other detachable structures in the prior art to connect the roller brush 22 to the locking member 27, such as magnetic adsorption.

[0102] In some possible implementations, the second pin 21801 is connected to a driven gear (not shown in the figure), and the rotating driving member 23 is connected to a driving gear (not shown in the figure) meshing with the driven gear.

[0103] Thus, the transmission between the rotating driving member 23 and the second pin 21801 is realized by the core of the driving gear and the driven gear, and due to the gear meshing properties, when the pin is detached from the support 21 along with the locking member 27, the second pin 21801 can be disengaged from the driving of the rotating driving member 23.

[0104] To further facilitate the meshing between gears, both the driving gear and the driven gear can be bevel gears.

[0105] See also Figure 8 In order to further improve the rotation stability between the locking member 27 and the roller brush 22, in some possible implementation modes, a connecting protrusion 219 is provided on one of the locking member 27 and the roller brush 22, and a connecting groove portion 220 is provided on the other of the locking member 27 and the roller brush 22. The connecting protrusion 219 is inserted into the connecting groove portion 220 and maintains a gap with the connecting groove portion 220 in the circumferential direction so as to be rotatable relative to the connecting groove portion 220. A sealing structure (not shown in the figure) is provided in the gap between the connecting protrusion 219 and the connecting groove portion 220.

[0106] See also Figure 8 The connecting protrusion 219 is arranged on the side of the locking member 27 facing the roller brush 22 , and is integrally formed with the locking member 27 . The connecting groove portion 220 is arranged on the roller brush 22 , and the connecting protrusion 219 can be rotatably inserted into the connecting groove portion 220 .

[0107] See also Figure 8 In some possible implementations, for ease of processing, the connecting groove portion 220 is disposed on an intermediate connecting member 221 that is plug-connected to the roller brush 22 .

[0108] The intermediate connecting member 221 is plugged and fixed with the roller brush 22 , and the connecting groove portion 220 is arranged on the intermediate connecting member 221 to reduce the processing difficulty.

[0109] In some possible implementations, the sealing strip may be a silicone sealing ring or a rubber sealing ring.

[0110] Of course, in some other possible implementations, the sealing structure may be replaced by other elastic waterproof and dustproof structures in the prior art.

[0111] See also Figure 4 , Figure 5 In order to achieve a detachable connection between the locking member 27 and the mounting hole 2103, in some possible implementations, a locking portion 216 is provided on one of the locking member 27 and the mounting hole 2103, and a matching groove 217 matching the locking portion 216 is provided on the other.

[0112] Therefore, after the roller brush 22 is installed on the support 21, it is locked and fixed by the locking portion 216 and the matching groove 217, and then the roller brush 22 is installed on the support 21. When disassembling, it is only necessary to release the locking portion 216 and the matching groove 217, separate the locking piece 27 from the support 21, and then the roller brush 22 can be detached from the support 21.

[0113] In some possible implementation manners, a twisting grip portion (not marked in the figure) is provided on the roller brush 22 , and the twisting grip portion is located on a side of the roller brush 22 facing outward from the support 21 .

[0114] In some possible implementations, the matching groove 217 is a snap-fit ​​groove, and the locking portion 216 is a snap-fit ​​protrusion that matches the snap-fit ​​groove.

[0115] See also Figure 5 In some possible implementations, the mating groove 217 includes a plug-in portion 21701 along the plug-in direction of the roller brush 22 and a locking portion 21702 vertically connected to the plug-in portion 21701; when the locking member 27 is locked, the snap-in protrusion is inserted into the plug-in portion 21701, and the snap-in protrusion is rotated from the plug-in portion 21701 to the locking portion 21702, so that the locking member 27 is locked and fixed to the mounting hole 2103, that is, locked and fixed to the support 21; when unlocking, the snap-in protrusion is rotated from the locking portion 21702 to the plug-in portion 21701, and then the snap-in protrusion can be pulled out from the plug-in portion 21701, and then the roller brush 22 can be subsequently disassembled.

[0116] In some possible implementations, the matching groove 217 is a thread groove 5 , and the locking portion 216 is an external thread that matches the thread groove 5 .

[0117] Of course, in other possible implementations, the locking member 27 and the mounting member may be detachably connected by snap-fit ​​connection or screw connection.

[0118] See also Figure 4 In some possible implementations, the collection box 25 is detachably connected to the support 21 .

[0119] Thus, the collection box 25 can be removed from the support 21 for cleaning or replacement and maintenance.

[0120] Furthermore, a filter (not shown in the figure) is provided at the connection point between the collecting box 25 and the negative pressure generating device 24 .

[0121] Thus, the dirt is filtered by the filter and remains in the collection box 25 , thereby avoiding damage to the negative pressure generating device 24 .

[0122] In some possible implementations, the filter is detachably connected to the collection box 25 or the support 21 .

[0123] Thus, the filter can be removed from the collection box 25 or the support 21 for cleaning or replacement and maintenance.

[0124] See also Figure 4 , Figure 7 In some possible implementations, a mounting groove 2104 is provided on the side of the support 21, and the collection box 25 is snap-fitted with the mounting groove 2104. A dust suction air inlet 2105 connected to the roller brush chamber 2102 is provided in the mounting groove 2104, and a docking port 2501 docking with the dust suction air inlet 2105 is provided on the collection box 25.

[0125] Thus, by the snap-fitting cooperation between the collection box 25 and the mounting groove 2104 , the collection box 25 and the support 21 are detachably connected, and the dirt is guided into the collection box 25 for collection through the dust suction air inlet 2105 .

[0126] In some possible implementations, a snap-in protrusion (not marked in the figure) is disposed on the bottom surface of the mounting groove 2104, and a snap-in groove (not marked in the figure) cooperating with the snap-in protrusion is disposed on the lower surface of the collection box 25.

[0127] Of course, the snap-on protrusions can also be arranged on other surfaces of the inner edge of the installation groove 2104 that are perpendicular to the plugging direction of the collection box 25, and the snap-on grooves only need to be arranged corresponding to the snap-on protrusions.

[0128] In addition, the snap-on protrusion may also be provided on the collection box 25 , and the snap-on protrusion provided on the mounting groove 2104 may also realize the snap-on connection of the collection box 25 .

[0129] In other possible implementations, the collection box 25 may be fixed to the support 21 via a threaded connection such as a screw.

[0130] See also Fig.10 , Fig.11 In some possible implementations, a backflow prevention plate 2502 is further provided in the collection box 25. The backflow prevention plate 2502 extends obliquely from the side where the docking port 2501 is located toward the middle of the collection box 25, and the backflow prevention plate 2502 extends upward from the bottom of the docking port 2501.

[0131] As a result, the dirt enters the collection box 25 along the anti-backflow plate 2502 under the action of negative pressure. When passing the end of the anti-backflow plate 2502, the dirt falls due to gravity, and is collected in the collection box 25. Due to the inclined setting of the anti-backflow plate 2502, the dirt in the collection box 25 can be prevented from flowing back out of the support 21 from the dust suction air inlet 2105 through the docking port 2501, which is also beneficial to increase the collection capacity of the collection box 25.

[0132] See also Fig.10 , Fig.11 In some possible implementations, a downwardly disposed guide plate 2503 is disposed at the end of the deflector plate away from the docking port 2501 .

[0133] Therefore, the provision of the guide plate 2503 can further prevent dirt from flowing back out of the collection box 25 .

[0134] In some possible implementations, the guide plate 2503 is arc-shaped.

[0135] Therefore, the arc-shaped guide plate 2503 can achieve smooth guidance of the airflow and reduce the generation of noise and vibration.

[0136] Of course, when the requirements for vibration and noise are not high, the guide plate 2503 can also be set as a straight plate.

[0137] See also Fig.10 , Fig.11 In some possible implementations, the collection box 25 is provided with an air outlet 2504 , the air outlet 2504 and the docking port 2501 are respectively located on two adjacent side surfaces of the collection box 25 , and a filter is provided at the air outlet 2504 .

[0138] Therefore, such an arrangement can save space and further facilitate product miniaturization.

[0139] See also Fig.10 In some possible implementations, a connection port 2505 is provided on the side of the collection box 25 , a cover plate 2506 is plugged into the connection port 2505 , and the air outlet 2504 is opened on the cover plate 2506 .

[0140] Thus, the cover plate 2506 can be disassembled to clean and maintain the interior of the collection box 25, making it easier to clean the collection.

[0141] In some possible implementations, the filter is a breathable filter screen (not shown in the figure) or a filter cloth (not shown in the figure) connected to the cover plate 2506 and covering the air outlet 2504 .

[0142] Thus, the structure is simplified, the overall weight of the cleaning device can be reduced, and the portability of the cleaning device is achieved.

[0143] Of course, other filters or filter structures in the prior art may also be applicable to this solution.

[0144] The use process and principle of the embodiment of the present invention are as follows:

[0145] When using the multifunctional cleaning device, the steam brush head 1 and the roller brush device 2 can be disassembled, so that the roller brush device 2 and the steam brush head 1 can be used independently, that is, the roller brush device 2 can independently perform dust removal or hair removal operations on clothes, and the steam brush 1 can independently perform ironing operations. Of course, after the steam brush head 1 and the roller brush device 2 are assembled, when the steam brush head 1 is not fed with steam, it can be used as a handle of the roller brush device 2.

[0146] When steam ironing and roller brush hair removal are required, the steam brush head 1 is assembled with the roller brush device. When in use, the overall brush head 1 provides high-temperature steam to iron clothes, and can perform high-temperature sterilization and deodorization. In addition, it can soften dirt, making it easy to separate the dirt from the clothing material. When cleaning the surface to be treated, such as the surface of clothing, the roller brush 22 driven by the rotating driving member 23 rotates, and the roller brush 22 rotates to slap the dirt on the surface to be cleaned, so that it is loosened and easy to separate from the surface to be cleaned, and then the negative pressure generating device 24 generates negative pressure suction, and the dirt is adsorbed from the surface to be cleaned through the cleaning port 2101 and collected in the collection box 25, and the dirt is filtered by the filter so that it stays in the collection box 25, thereby avoiding damage to the negative pressure generating device 24, thereby improving the cleaning effect.

[0147] In summary, the multifunctional cleaning device provided by the present invention has the advantages of diverse functions, easy assembly and maintenance, and compact structure, and is particularly suitable for clothing care at home or during travel.

[0148] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
