[0089] According to one aspect of the present disclosure, the present disclosure provides a surface cleaning device, which can be used for dry cleaning or wet cleaning of a surface to be cleaned. In dry cleaning, the surface cleaning device does not need to provide cleaning liquid to the floor brush assembly 10; in wet cleaning, the surface cleaning device can provide cleaning liquid to the floor brush assembly 10, and the amount of the cleaning liquid provided can vary depending on the degree of dirtiness of the surface to be cleaned.

[0090] In one embodiment, the cleaning of the surface to be cleaned is achieved through frictional contact between the floor brush assembly 10 of the surface cleaning device and the surface to be cleaned.

[0091] The structure of the floor brush assembly 10 will be described in detail below with reference to the accompanying drawings.

[0092] Figure 1 1 is a schematic structural diagram of a floor brush assembly 10 of a surface cleaning device according to an embodiment of the present disclosure.

[0093] like Figure 1 The floor brush assembly 10 shown includes a connecting portion 100, so as to connect the floor brush assembly 10 to the main body of the surface cleaning device through the connecting portion 100. In one embodiment, the main body of the surface cleaning device has a suction device, and when the connecting portion 100 is connected to the main body of the surface cleaning device, a suction airflow can be provided to the floor brush assembly 10.

[0094] In one implementation, the connection portion 100 may be formed as a snap-fit ​​structure, thereby facilitating the user to install the floor brush assembly 10 on the main body of the surface cleaning device and to remove the floor brush assembly 10 from the main body of the surface cleaning device.

[0095] In a preferred embodiment, an electrical connection terminal 110 is also provided on the connecting part 100, so that when the connecting part 100 is connected to the main body of the surface cleaning device, the electrical connection terminal 110 can be connected to the battery of the main body to supply power to the driving device 160 of the floor brush assembly 10.

[0096] The floor brush assembly 10 may further include a shell 200 , wherein the shell 200 is connected to the connecting portion 100 via a connecting member 120 . In a preferred embodiment, the connecting member 120 may be a universal joint, thereby enabling the main body to tilt in multiple directions relative to the shell 200 .

[0097] In one embodiment, a rotating wheel 130 is rotatably provided on the housing 200 , so that when the floor brush assembly 10 performs a cleaning operation, the floor brush assembly 10 is moved by the rotation of the rotating wheel 130 on the surface to be cleaned.

[0098] More specifically, the number of the rotating wheels 130 can be set to two, and the two rotating wheels 130 are respectively located on both sides of the shell 200, so that the shell 200 can be stably supported by the two rotating wheels 130 to improve the stability of the entire floor brush assembly.

[0099] Refer to Figure 1 , the floor brush assembly 10 may further include a cover member 300, and the cover member 300 is disposed on the housing 200. In one embodiment, the cover member 300 is detachably disposed on the housing 200, and a receiving space is formed between the cover member 300 and the housing 200, and some parts of the floor brush assembly 10, such as the driving device 160, etc., may be disposed in the receiving space. In the present disclosure, the receiving space 210 may also be referred to as a roller brush chamber, a roller brush chamber, or a brush roller chamber, etc.

[0100] Figure 2 It is a partial structural schematic diagram of a floor brush assembly of a surface cleaning device according to one embodiment of the present disclosure.

[0101] like Figure 2 As shown, the shell 200 includes a accommodating space 210 and a suction opening 220 connected to the accommodating space 210; wherein, the accommodating space 210 can accommodate components such as the first stirring body 500, and the suction opening 220 can be connected to the suction pipe 140, so that a mixture of dust and gas, or a mixture of dust, used cleaning liquid and gas can pass through the suction opening 220, enter the suction pipe 140, and be sucked into the main body of the surface cleaning device via the suction pipe 140.

[0102] In a preferred embodiment, the cover component 300 and the housing 200 jointly form a receiving space 210 described below; in a more preferred embodiment, the cover component 300 and the housing 200 jointly form a suction opening 220 described below.

[0103] In the present disclosure, the floor brush assembly 10 further includes a bracket portion 150 ; in one embodiment, the bracket portion 150 may be fixed to the housing 200 , and of course, the bracket portion 150 may also be fixed to a cover component 300 or other structures.

[0104] The bracket 150 is used to fix the driving device 160. In one embodiment, the driving device 160 can be a common motor such as a DC motor or a stepping motor, and can be held by the bracket 150. Of course, the driving device 160 can also be fixed to the housing 200 and held by the housing 200. More preferably, the driving device 160 can be held by both the bracket 150 and the housing 200.

[0105] In a preferred embodiment, the bracket portion 150 can be formed separately from the shell 200 . Of course, those skilled in the art should know that the bracket portion 150 can also be formed integrally with the shell 200 .

[0106] like Figure 2 As shown, a driving synchronous pulley 170 is installed on the output shaft of the driving device 160, and a driven synchronous pulley 180 is installed on the driving rod 410. The driving synchronous pulley 170 and the driven synchronous pulley 180 are connected by a synchronous belt transmission, so that the driving rod 410 can be driven to rotate by the driving device 160. Of course, the synchronous belt transmission mechanism can also be replaced by a chain transmission mechanism or a gear transmission mechanism, etc., which will not be described in detail here.

[0107] Figure 3 It is a schematic cross-sectional structural diagram of a floor brush assembly according to an embodiment of the present disclosure.

[0108] like Figure 3 As shown, the floor brush assembly 10 may further include a bearing 400 . In one embodiment, the bearing 400 may be disposed in the housing 200 . In this case, a bearing seat may be formed on the housing 200 so that the bearing may be disposed in the bearing seat of the housing 200 .

[0109] In another embodiment, Figure 3 As shown, the bracket portion 150 is formed with a bearing seat, and the bearing 400 is disposed on the bearing seat of the bracket portion 150 , so that the bearing 400 is indirectly disposed on the housing 200 .

[0110] More preferably, if Figure 3 As shown, the bracket portion 150 is formed with a step portion 151 , and the bearing 400 can be positioned by the step portion 151 ; correspondingly, the bracket portion 150 is also formed with a hook portion 152 , and the bearing 400 can also be positioned by the hook portion 152 .

[0111] In a preferred embodiment, the number of the bearings 400 is two, for example, two ball bearings. Of course, the two bearings 400 can also be angular contact bearings installed back to back or face to face.

[0112] The outer ring of one of the two bearings 400 is positioned by the step portion 151 , and the outer ring of the other of the two bearings 400 is positioned by the hook portion 152 , thereby achieving the fixing of the axial positions of the two bearings 400 .

[0113] like Figure 3As shown, the floor brush assembly 10 of the present disclosure also includes a driving rod 410, which is disposed on the bearing 400 and is rotatably supported by the bearing 400. That is, the driving rod 410 can be fixed to the inner ring of the bearing 400. For example, the size of the driving rod 410 can be slightly larger than the inner diameter of the inner ring of the bearing 400, so that the driving rod 410 cannot generate axial movement relative to the bearing 400 through interference fit.

[0114] Furthermore, due to the characteristics of the bearing 400 , the driving rod 410 can rotate. At this time, the driving device 160 can drive the driving rod 410 to rotate.

[0115] In the present disclosure, one end of the driving rod 410 is located in the accommodating space 210 , and the first stirring body 500 is installed at this end; the other end of the driving rod 410 is located outside the accommodating space 210 , and the driven synchronous pulley 180 is installed at this end.

[0116] like Figure 2 and Figure 3 As shown, the floor brush assembly 10 of the present disclosure further includes a first stirring body 500 , which is disposed on the driving rod 410 and located in the accommodating space 210 , and the first stirring body 500 is driven to rotate by the driving rod 410 .

[0117] At this time, the bearing 400 is configured as follows: when the first stirring body 500 is installed on the driving rod 410, the first stirring body 500 is rotatably held on the shell 200 while the outer peripheral surface of the bearing 400 (i.e., the outer peripheral surface of the outer ring of the bearing 400) contacts the shell 200; and the outer diameter of the bearing 400 is less than or equal to the maximum diameter of the outer peripheral surface of the first stirring body 500.

[0118] Therefore, through the configuration of the above-mentioned bearing 400, the first stirring body 500 can be stably supported, thereby improving the operating stability of the floor brush assembly 10 and thus improving the cleaning effect of the surface to be cleaned.

[0119] In one embodiment, the outer diameter of the bearing 400 is smaller than or equal to the outer diameter of one end of the first stirring body 500 fixed to the driving rod 410 .

[0120] In another embodiment, the outer diameter of the bearing 400 is smaller than or equal to the minimum outer diameter of the outer circumference of the first stirring body 500. For example, the outer diameter of the bearing 400 is smaller than or equal to the outer diameter of the end of the first stirring body 500 away from the driving rod 410.

[0121] In this disclosure, Figure 3As shown, the driving rod 410 includes a driving shaft 411 and a driving member 412, wherein one end of the driving shaft 411 passes through the bearing 400 and is at least partially located in the accommodating space 210, and the driving member 412 is installed on the one end of the driving shaft 411 and is located in the accommodating space 210; wherein the driving shaft 411 is fixed with the above-mentioned driven synchronous pulley 180, and the driving member 412 is transmission-connected to the first stirring body.

[0122] The structure of the first stirring body 500 is described in detail below with reference to the accompanying drawings.

[0123] Figure 5 It is a schematic structural diagram of a stirring member according to an embodiment of the present disclosure.

[0124] In one embodiment, Figure 2 As shown, the first stirring body 500 is suspended so that the first stirring body 500 has a fixed end and a free end, wherein the fixed end is an end connected to the driving rod 410, and the free end is an end suspended.

[0125] As an implementation form, the first stirring body 500 has a core 501 with an outer cylindrical surface, the diameters of both ends of the core 501 are substantially equal, and the outer diameter of the bearing 400 is greater than or equal to the diameter of the core 501 .

[0126] As another implementation, Figure 5 As shown, a spirally extending row of bristles 510 is provided on the outer surface of the core 501 of the first stirring body 500 in the direction from the fixed end to the free end, and the row of bristles 510 extends outward from the outer surface of the core 501 of the first stirring body 500 a first radial distance, and the first radial distance decreases successively from the fixed end to the free end of the first stirring body 500. At this time, when the first stirring body 500 rotates, the row of bristles 510 can contact the surface to be cleaned to disturb the dust on the surface to be cleaned.

[0127] More preferably, a spirally extending protrusion 520 is provided on the outer surface of the core 501 of the first stirring body 500 in a direction from the fixed end to the free end, and the bristle row 510 extends outward from the protrusion 520 .

[0128] In the present disclosure, the protrusion 520 extends outward from the outer surface of the core 501 of the first stirring body 500 by a second radial distance, and the second radial distance decreases from the fixed end to the free end of the first stirring body 500 .

[0129] In a specific implementation form, the protrusion 520 includes a base 521 and a pair of ridges 522, and the base 521 and the pair of ridges 522 are arranged radially outward from the outer surface of the core 501 of the first stirring body 500 in sequence, and the bristle row 510 extends outward from the base 521 and is arranged between the pair of ridges 522, and the top end of the bristle row 510 extends out of the pair of bases 521.

[0130] In one implementation form, the base 521 has a third radial distance, and the third radial distance decreases from the fixed end to the free end of the first stirring body 500, and the bristle row 510 has a constant fourth radial distance.

[0131] In another implementation form, the base 521 has a constant third radial distance, and the bristle row 510 has a fourth radial distance, and the fourth radial distance decreases sequentially from the fixed end to the free end of the first stirring body 500 .

[0132] like Figure 2 As shown, in the present disclosure, two first stirring bodies 500 are provided, and the ends of the two first stirring bodies 500 are arranged close to each other and have a preset distance; more preferably, the gap between the two first stirring bodies 500 corresponds to the position of the suction opening, thereby, the disturbed dust can be transported to the vicinity of the suction opening along with the spirally arranged protrusion 520, so that the disturbed dust can be conveniently sucked into the suction opening, thereby greatly improving the cleaning effect.

[0133] In one embodiment, the first stirring bodies 500 are driven by respective driving devices 160 , that is, when two first stirring bodies 500 are provided, two driving devices 160 are also provided.

[0134] Figure 6 is a schematic structural diagram of a cover component according to an embodiment of the present disclosure.

[0135] like Figure 6 As shown, the cover member 300 includes a pair of tapered inner walls 310 , and the outer surface of the first agitating body 500 contacts the tapered inner walls 310 .

[0136] More preferably, the pair of tapered inner walls 310 include a junction, which is the intersection of the two tapered inner walls 310 , and the position of the junction corresponds to the position of the gap between the free ends of the pair of first stirring bodies 500 . Furthermore, the position of the junction corresponds to the position of the suction opening 220 .

[0137] Continue to refer Figure 2, the first stirring body 500 of the present disclosure is arranged transversely, for example, arranged transversely in the accommodation space, wherein when the surface cleaning device is in use, the user moves the floor brush assembly forward or backward, thereby, the front-to-back direction of the floor brush assembly is the longitudinal direction of the floor brush assembly, and the transverse direction is perpendicular to the longitudinal direction. Those skilled in the art should know that the transverse direction does not refer to the horizontal direction, and the transverse direction may be at a certain angle to the horizontal direction. In this case, during use, the longitudinal axis of the first stirring body 500 is approximately perpendicular to the moving direction of the floor brush assembly.

[0138] More preferably, the floor brush assembly may further include a second stirring body 600, which is rotatably disposed on the housing 200 and is located in front of the first stirring body 500, and a part of the vacuum flow channel is formed between the first stirring body 500 and the second stirring body 600, thereby, the surface to be cleaned can be cleaned more cleanly by the arrangement of the first stirring body 500 and the second stirring body 600. Specifically, when the surface cleaning device cleans the surface to be cleaned, when the floor brush assembly moves forward, the surface to be cleaned is first cleaned by the second stirring body 600 to stir the dust on the surface to be cleaned; then the surface to be cleaned is cleaned again by the first stirring body 500 to stir the dust on the surface to be cleaned, thereby making the surface to be cleaned cleaner after cleaning.

[0139] In the present disclosure, the second stirring body 600 can be driven to rotate. For example, the second stirring body 600 can be formed in the form of a cylindrical roller brush, and a driving device such as a motor can be arranged inside the second stirring body 600, so that the second stirring body 600 can rotate. Accordingly, at this time, both ends of the second stirring body 600 are rotatably supported on the housing 200 through bearings. In a preferred embodiment, the second stirring body 600 can also be arranged horizontally and horizontally.

[0140] In a preferred embodiment, the second stirring body 600 is a fluff brush, so hair and other objects are easily entangled on the second stirring body 600, and frequent cleaning and maintenance are required. However, the first stirring body 500 can adopt a roller brush with an anti-entanglement function, which does not require frequent cleaning. Based on this, in the present disclosure, through the provision of the cover component 620, only the second stirring body 600 is exposed, which facilitates the cleaning operation of the second stirring body 600.

[0141] In the present disclosure, the floor brush assembly may further include a cover component 620, which can be configured to be removed from the floor brush assembly and installed on the floor brush assembly. In a preferred embodiment, the cover component 620 can be detachably disposed on the housing 200 or the cover component 300.

[0142] After the cover part 620 is removed from the floor brush assembly, the first stirring body 500 forms a passage from the front side of the floor brush assembly to the outside world, and the user can clean the first stirring body 500, for example, clean the hair and other objects entangled on the first stirring body 500.

[0143] In one implementation, the cover component 620 includes a rear wall. When the cover component 620 is located in the floor brush assembly, that is, when the cover component 620 is installed on the shell 200 or the cover component 300, the rear wall and the shell form a accommodating space for the first stirring body 500. That is to say, the rear end of the cover component 620 terminates near the first stirring body 500. Therefore, when the cover component 620 is removed from the floor brush assembly, the first stirring body 500 can be easily cleaned.

[0144] Figure 7 It is a schematic diagram of the structure of a floor brush assembly viewed from above according to one embodiment of the present disclosure.

[0145] In a specific example, Figure 7 As shown, the floor brush assembly further includes: a cleaning assembly, which is disposed between the first stirring body 500 and the second stirring body 600 so as to clean the first stirring body 500 and the second stirring body 600 through the cleaning assembly.

[0146] Therefore, when the floor brush assembly of the present disclosure is in use, the first stirring body 500 and the second stirring body 600 can be cleaned, so that the first stirring body 500 and the second stirring body 600 are always in a clean state, thereby effectively improving the cleaning effect of the surface to be cleaned.

[0147] In the present disclosure, the cleaning assembly may include: a support wall 810 , a first cleaner 820 , a second cleaner 640 and other components.

[0148] The first cleaner 820 interferes with the first stirring body 500 so as to clean the first stirring body 500 through the first cleaner 820 ; and / or the second cleaner 640 interferes with the second stirring body 600 so as to clean the second stirring body 600 through the second cleaner 640 .

[0149] The support wall 810 is formed by extending from the shell 200; of course, those skilled in the art should know that the support wall 810 can also be formed independently and fixed to the shell 200; in a preferred embodiment, the support wall 810 can pass through the shell 200, and of course, the support wall 810 may not pass through the shell 200.

[0150] The first cleaner 820 is formed on the side of the support wall 810; that is, when the support wall 810 is in the working state, as the first stirring body 500 turns in different directions, the first stirring body 500 can contact the upper edge or the lower edge of the first cleaner 820, thereby removing solid waste such as dust on the surface of the first stirring body 500. In a preferred embodiment, the first cleaner 820 only contacts the bristle row 510 of the first stirring body 500, thereby cleaning the dirt on the bristle row 510.

[0151] In this disclosure, Figure 3 As shown, the support wall 810 is configured to extend from the shell 200 in a gradually widening manner along the direction from the fixed end to the free end of the second stirring body, so that the first cleaner 820 interferes with the first stirring body 500 in the direction from the fixed end to the free end of the first stirring body 500.

[0152] When the number of the first stirring bodies 500 is different, the structure of the first cleaner is also different accordingly. For example, when the number of the first stirring body 500 is one, the support wall 810 can be changed as the outer surface of the core 501 of the first stirring body 500 changes.

[0153] On the other hand, when the number of the first stirring bodies 500 is two, the first cleaner 820 may include a first inclined portion 821 and a second inclined portion 822, and the first inclined portion 821 and the second inclined portion 822 are formed into a V-shaped structure, and the corner of the V-shaped structure faces the suction opening 220, thereby enabling the first cleaner 820 to simultaneously clean the two first stirring bodies 500.

[0154] The first cleaner 820 is configured to extend from the support wall 810 in a gradually widening manner along the direction from the fixed end to the free end of the first stirring body 500, so that the first cleaner 820 interferes with the first stirring body 500 in the direction from the fixed end to the free end of the first stirring body 500.

[0155] In the present disclosure, the core 501 includes a conical portion and / or a straight cylindrical portion. As different implementation forms, from the fixed end to the free end of the first stirring body 500: the core 501 includes a straight cylindrical portion, a conical portion and a straight cylindrical portion in sequence, or the core 501 includes a straight cylindrical portion and a conical portion in sequence, or the core 501 includes a conical portion and a straight cylindrical portion in sequence.

[0156] Figure 8 is a schematic structural diagram of a second cleaner according to an embodiment of the present disclosure. Fig. 9 yes Figure 8 A magnified schematic diagram of part A.

[0157] In a specific example, Figure 8 and Fig. 9 As shown, the second cleaner 640 includes cleaning protrusions 641 arranged at intervals along the length direction of the second stirring body 600, and the cleaning protrusions 641 partially extend into the second stirring body 600 and have a lower edge, and the lower edge is aligned with the axis of the second stirring body 600 or is located below the axis of the second stirring body 600; wherein, the second cleaner 640 is located on the front side of the support wall, and correspondingly, the first cleaner can be located on the rear side of the support wall.

[0158] Fig.11 is a schematic structural diagram of a second cleaner according to an embodiment of the present disclosure.

[0159] like Fig.11 As shown, the lower edge of the cleaning protrusion 641 is inclined so that the cleaning protrusion is lower than the horizontal plane where the axis of the second stirring body 600 is located as a whole.

[0160] More preferably, the cleaning protrusion 641 also includes an upper edge, and the front end of the upper edge of the cleaning protrusion 641 is inserted into the second stirring body 600, so that the part of the cleaning protrusion 641 inserted into the second stirring body 600 is formed into a pointed shape. At this time, the hair and other objects cleaned by the cleaning protrusion 641 can be maintained at the upper edge position of the cleaning protrusion 641.

[0161] In the present disclosure, the upper edge of the cleaning protrusion 641 is tilted downward in the direction from front to back, so that the cleaning protrusion 641 can accommodate more garbage, thereby extending the time between two disassemblies of the second stirring body 600.

[0162] In a preferred embodiment, the axis of the second stirring body 600 is horizontally arranged transversely.

[0163] In the present disclosure, the floor brush assembly may further include a latch (not shown in the drawings), which is configured to engage with the cover component 620 to removably connect the cover component 620 to the housing 200 or the cover component 300 .
