At the same time, long hair will accumulate in the sewage tank of the scrubber, which will also bring cleaning difficulty or blockage of the sewage pipe. SUMMARY

[0003] Therefore, the utility model discloses the purpose of providing a kind of cleaning equipment, comprising: floor brush subassembly, floor brush subassembly includes rotatable brush roller, and brush roller is used to clean the surface to be cleaned;Dirty recovery system, dirty recovery system includes dirty recovery tank, suction nozzle, air duct and vacuum suction source;Wherein, air duct is used to connect suction nozzle and dirty recovery tank, dirty recovery system generates suction force by vacuum suction source, so that suction nozzle sucks dirty from brush roller or surface to be cleaned, dirty enters dirty recovery tank after passing through air duct;Air duct includes hair processing device, for processing long hair into short hair;Hair processing device includes winder and hair cutter;Winder includes driving motor and support structure, driving motor is used to drive support structure to rotate, and the outer periphery side of support structure is used to wind hair;Hair cutter includes execution end and elastic support, and the end of execution end can at least partially abut with support structure when support structure rotates, to rub off hair wound on the outer periphery side of support structure, and elastic support is arranged at the end of execution end away from support structure.

[0004] In one aspect, the brush roller of the floor brush assembly cleans the surface to be cleaned, the vacuum suction source generates suction force, which can suck the dirt on the surface to be cleaned into the suction nozzle, at the same time, the entangler in the air duct starts to rotate under the drive of the driving motor, the long hair entering the air duct will be captured and entangled on the outer circumferential side of the support structure of the entangler, and other dirt such as sewage will be sucked into the dirt recovery tank. After the long hair is captured by the entangler, it is squeezed between the entangler and the hair cutter, and when the entangler rotates, the support structure and the execution end of the hair cutter generate friction. The long hair squeezed between the two is ground by the friction force, so that the long hair becomes short hair, for example, the length of the ground short hair is between 2-4 cm. The shortened hair will not be entangled on the entangler, and under the action of the vacuum suction source, it is easier to be collected by the sewage tank and other collection devices of the cleaning equipment, so as to prevent the air duct of the cleaning equipment from being blocked, and the short hair is not easy to agglomerate in the dirt recovery tank, so that the user can better clean the dirt recovery tank, and the dirt is not easy to block the drain pipe. On the other hand, the hair processing device is arranged in the air duct, which can save the space of the floor brush assembly, effectively utilize the space of the floor cleaning machine, make the structure of the floor brush assembly more compact, and the entangler is driven to rotate by the motor, which can timely capture and entangle the long hair, and continuously process the long hair into short hair. The whole process is compact and efficient.

[0005] Further, the hair cutter is adjustably arranged in the air duct; or the hair cutter is fixedly arranged. The adjustably arranged hair cutter in the air duct can adjust the position of the hair cutter in real time, so as to perform hair cutting operation on the hair at different positions of the entangler, and the fixedly arranged hair cutter can perform hair cutting operation on the hair when the hair has a preset thickness. The specific selection can be made according to actual needs.

[0006] Further, the execution end of the hair cutter provides a friction surface, and when the support structure rotates to abut against the friction surface, the elastic support member is in a compressed state, and the hair on the support structure is squeezed and rubbed between the friction surface and the support structure.

[0007] Therefore, the elastic support member in the compressed state can provide abutting driving force for the hair cutter, ensure that the entangler and the hair cutter generate sufficient friction force, and make the long hair ground into short hair.

[0008] Further, the friction surface is an inner concave arc surface, and the arc surface has an extension trend along the rotation direction of the entangler.

[0009] Therefore, the inner concave arc surface can reserve a rotation space for the rotation of the support structure of the entangler, so that the whole rotation and friction process is more continuous and smooth.

[0010] Further, the support structure comprises a middle shaft and at least one blade fixed on the middle shaft, and the blade extends along the direction of the middle shaft.

[0011] Thus, the blade structure occupies less space of the air duct, and a larger space can be reserved for the air duct, so that the passing of other dirt in the air duct is not affected, and the dirt is not easy to accumulate or even block at this position.

[0012] Further, the blade is in an arc shape protruding towards the rotation direction.

[0013] Thus, the arc shape of the blade can cooperate with the arc shape of the execution end of the hair cutter, so that the blade has a larger contact area with the execution end of the hair cutter when rotating, improving the grinding efficiency of long hair.

[0014] Further, when the winding device rotates, the execution end of the hair cutter first abuts against the root position of the blade close to the central axis, and the abutting position gradually moves to the end position of the blade away from the central axis.

[0015] Thus, the surface area of the side of the blade can be fully utilized, and more friction contact area is provided within the same number of rotations of the winding device, improving the hair cutting efficiency.

[0016] Further, the air duct includes a sink portion for accommodating the hair cutter, and the sink portion has a communication opening, and the execution end of the hair cutter can extend into the inner cavity of the air duct through the communication opening. By setting the hair cutter in the sink portion, the execution end of the hair cutter extends out of the communication opening, so that only the execution end of the hair cutter is set in the inner cavity, which facilitates the fixing of the position of the hair cutter, and ensures that the part of the hair cutter in the inner cavity can complete the effective cutting operation.

[0017] Further, the hair cutter has a limiting portion, and the limiting portion is stopped by the edge of the communication opening to prevent the hair cutter from being pulled out of the communication opening. By providing the limiting portion on the hair cutter, the hair cutter is stopped by the edge of the communication opening, avoiding the hair cutter extending into the inner cavity being too long.

[0018] Further, the hair treatment device further includes a cover plate sealing the slot of the sink portion and connected with the outer surface of the air duct. By providing the cover plate, the position of the hair cutter in the sink portion can be checked in time, or the hair cutter can be installed or replaced.

[0019] Further, the winding device is close to the air outlet side of the air duct relative to the hair cutter.

[0041] In order to solve the problem that the air duct of the sweeper is easily blocked by hair in the prior art, the utility model provides a cleaning equipment.

[0042] The cleaning equipment will be described below.

[0043] As shown in Figures 1 to 8 The cleaning equipment includes a brush assembly 10, a dirt recycling system and a handle 60. The brush assembly 10 and the handle 60 are connected with the dirt recycling system. When in use, the cleaning equipment is placed on the surface to be cleaned through the handle 60, and the cleaning equipment is moved by operating the handle 60. In this process, the brush assembly 10 removes the dirt on the surface to be cleaned, and the dirt is absorbed and stored by the dirt recycling system.

[0044] As shown in Figures 1 to 7 The brush assembly 10 includes a rotatable brush roller 11. The brush roller 11 is used to clean the surface to be cleaned. During use of the cleaning equipment, the brush roller 11 rotates at the front end of the cleaning equipment, thereby cleaning the dirt on the surface to be cleaned. In order to avoid splashing of the dirt on the brush roller 11 due to rotation of the brush roller 11 during cleaning, the brush assembly 10 further includes a baffle 12. The baffle 12 is arranged above the brush roller 11, the baffle 12 can fit the entire brush roller 11, and the baffle 12 is an arc-shaped plate, and the baffle 12 partially covers the brush roller 11. Optionally, the baffle 12 can cover one half or one quarter of the brush roller 11.

[0045] As shown in Figures 1 to 7As shown, the dirt collection system comprises a dirt collection tank 20, a suction nozzle 30, an air duct 40 and a vacuum source. The air duct 40 is used to connect the suction nozzle 30 and the dirt collection tank 20. The dirt collection system generates suction force through the vacuum source, so that the suction nozzle 30 sucks dirt from the brush roller 11 or the surface to be cleaned, and the dirt enters the dirt collection tank 20 through the air duct 40. The vacuum source is arranged above the dirt collection tank 20. Optionally, a switch for controlling the vacuum source is arranged on the handle 60, and the user controls the opening and closing of the vacuum source through the switch.

[0046] As shown in Figures 1 to 2 In order to facilitate the installation of the air duct 40, the application further comprises a bottom shell 50. The bottom shell 50 is divided into upper and lower parts. The bottom shell 50 has a receiving cavity, and the air duct 40 is received in the bottom shell 50. The brush roller 11 is arranged at the front end of the bottom shell 50. One end of the bottom shell 50 is provided with the suction nozzle 30, which is arranged corresponding to the brush roller 11. The other end of the bottom shell 50 is connected to the dirt collection tank 20. The two ends of the air duct 40 are respectively connected to the suction nozzle 30 and the dirt collection tank 20, so that the suction nozzle 30 is located at the air inlet side 45 of the air duct 40, and the dirt collection tank 20 is arranged at the air outlet side 46.

[0047] As shown in Figures 1 to 8 The air duct 40 comprises a hair treatment device for treating long hair into short hair. The hair treatment device comprises a winding device 41 and a hair breaking device 42. The winding device 41 comprises a driving motor 411 and a support structure 412. The driving motor 411 is used to drive the support structure 412 to rotate. The outer circumferential side of the support structure 412 is used to wind hair. The hair breaking device 42 comprises an execution end 421 and an elastic support 422. When the support structure 412 rotates, one end of the execution end 421 can at least partially abut against the support structure 412, so as to break the hair wound on the outer circumferential side of the support structure 412. The elastic support 422 is arranged at the end of the execution end 421 away from the support structure 412.

[0048] In one aspect, the brush roller 11 of the floor brush assembly 10 cleans the surface to be cleaned, the suction force generated by the vacuum suction source can suck the dirt on the surface to be cleaned into the suction nozzle 30, at the same time, the entangler 41 in the air duct 40 starts to rotate under the driving of the driving motor 411, the long hair entering the air duct 40 can be captured and wound on the outer circumferential side of the support structure 412 of the entangler 41, and other dirt such as sewage can be sucked into the dirt recovery tank 20. The long hair captured by the entangler 41 is extruded between the entangler 41 and the hair cutter 42, and when the entangler 41 rotates, the support structure 412 and the execution end of the hair cutter 42 rub, and the long hair extruded between them is ground by the friction force, so that the long hair becomes short hair, for example, the length of the ground short hair is between 2-4 cm. The shortened hair cannot be wound on the entangler 41, and under the action of the vacuum suction source, it is more easily collected by the sewage tank and other collection devices of the cleaning equipment, so as not to easily cause the air duct 40 of the cleaning equipment to be blocked, and the short hair is not easy to agglomerate in the dirt recovery tank 20, the user can better clean the dirt recovery tank 20, and the dirt is not easy to block the drain pipe. On the other hand, the hair processing device is arranged in the air duct 40, which can save the space of the floor brush assembly 10, effectively utilize the space of the scrubber, make the structure of the floor brush assembly 10 more compact, the entangler 41 is driven to rotate by the motor, can timely capture and wind the long hair, and continuously process the long hair into short hair, the whole process is compact and efficient.

[0049] Since the main purpose of the utility model is to cut the long hair on the entangler 41, more variable embodiments can be considered from the following improvement directions. For example: the hair cutter 42 can have multiple implementation modes; the specific setting position of the hair cutter 42 can have multiple implementation modes; whether the hair cutter 42 is movable; the fixing mode of the hair cutter 42; and whether the entangler 41 has a function of changing position in addition to rotation. Next, the variable and implementation modes described above will be described in detail.

[0050] In this embodiment, the hair cutter 42 is adjustably arranged in the air duct 40. The adjustably arranged hair cutter 42 in the air duct 40 can adjust the position of the hair cutter 42 in real time, so as to cut the hair at different positions of the entangler 41, and the fixed arrangement of the hair cutter 42 can cut the hair when the hair has a preset thickness. The specific selection can be made according to actual needs.

[0051] It can be understood that the position adjustment of the hair cutter 42 includes two adjustment modes, one is passive adjustment, and the other is active adjustment. The passive adjustment mode of the hair cutter 42 is that the hair cutter 42 is affected by the thickness of the hair when the hair cutter 42 contacts the hair of different thicknesses, so as to passively adjust the position of the hair cutter 42. The active adjustment mode is that the hair cutter 42 actively adjusts the position of the hair cutter 42 according to the thickness and position of the hair. The following is described in a specific manner.

[0052] The utility model adopts the passive adjustment mode of the hair cutter 42, as shown in Figure 2 、 Figures 6 to 7 In order to facilitate the position adjustment of the hair cutter 42, the hair processing device further includes an elastic support 422 abutting against one side of the hair cutter 42 opposite to the execution end 421. The elastic support 422 can realize adaptive automatic adjustment of the position of the hair cutter 42 when the hair cutter 42 cuts the hair of different thicknesses.

[0053] Specifically, the hair cutter 42 is provided with a mounting groove 424 at one end opposite to the execution end 421, and a section of the elastic support 422 is accommodated in the mounting groove 424, and the other end of the elastic support 422 abuts against the inner wall of the air duct 40. The elastic support 422 and the mounting groove 424 are both two and are one-to-one corresponding. The two elastic supports 422 can avoid the shaking of the hair cutter 42 inside the air duct 40, ensure that the extension direction of the hair cutter 42 is always perpendicular to the extension direction of the winding device 41, and further ensure that each cutting of the hair cutter 42 can realize effective cutting.

[0054] In the embodiment, the elastic support 422 is a spring, and of course can also be other structural members. When the thickness of the hair on the winding device 41 is large, the hair cutter 42 is extruded by the hair, so that the hair cutter 42 moves a distance away from the hair and compresses the elastic support 422. When the thick hair is cut, the elastic support 422 resets and drives the hair cutter 42 to be close to the winding device 41, so as to cut the hair of small thickness, and ensure the effectiveness of the hair processing.

[0055] In another embodiment of the utility model not shown in the figure, the hair cutter 42 adopts the active adjustment mode, and the hair processing device further includes a hair recognition part and an adjustment structure. The hair recognition part is arranged towards the winding device 41, the hair recognition part is electrically connected with the adjustment structure, and the adjustment structure is drivingly connected with the hair cutter 42 to adjust the position of the hair cutter 42. The hair recognition part and the adjustment structure cooperate to realize the real-time adjustment of the position of the hair cutter 42, so as to ensure the effective hair cutting and improve the efficiency of the hair processing.

[0056] Specifically, the hair recognition part can recognize the position of the hair winding on the winding device 41, and the hair recognition part can be an infrared emitter or other forms of detection structure. The adjusting structure is arranged inside the air duct 40 or partially arranged inside the air duct 40 and connected with the hair cutter 42. The position of the hair entering the air duct 40 is different, so that the position of the hair winding on the winding device 41 is different, or the thickness of the hair winding on the winding device 41 is different. After the hair recognition part recognizes the position of the hair, a signal is sent to the adjusting structure, so that the adjusting structure adjusts the position of the hair cutter 42 according to the position of the hair, and ensures the efficiency of the hair cutting. Optionally, the adjusting structure is an adjusting motor, and the adjusting motor drives the hair cutter 42 to move along the length direction of the winding device 41, so as to complete the hair cutting at different positions of the winding device 41.

[0057] In an embodiment of the utility model not shown in the figure, the hair cutter 42 is fixedly arranged. No matter whether the position of the hair cutter 42 is adjustable or fixed, as long as the hair cutter 42 can contact the long hair of the winding device 41 and can realize the cutting operation on the long hair.

[0058] Although the hair cutter 42 needs to cooperate with the winding device 41 to complete the cutting of the hair, according to the different cutting modes, the specific cooperation mode is also different when the hair cutter 42 cooperates with the winding device 41. It can be that the hair cutter 42 is arranged close to the winding device 41 or is arranged at intervals.

[0059] In the embodiment, the hair cutter 42 is adjustably arranged in the inner cavity of the air duct 40, so that the execution end 421 of the hair cutter 42 can move to the winding device 41. The execution end 421 of the hair cutter 42 is close to the winding device 41 by moving along the length direction of the air duct 40 in the inner cavity, so as to complete the cutting of the hair on the winding device 41. When the hair cutter 42 adopts the friction cutting mode of the hair, the hair cutter 42 moves to the winding device 41.

[0060] In an embodiment of the utility model not shown in the figure, the execution end 421 of the hair cutter 42 is arranged at intervals with the winding device 41. When the execution end 421 of the hair cutter 42 is arranged at intervals with the winding device 41, the hair cutter 42 adopts the cutting mode of the hair or the high-temperature cutting mode of the hair. The distance between the execution end 421 and the winding device 41 is too close, and there is a risk of damaging the winding device 41.

[0061] Since the hair cutter 42 needs to cut the long hair on the winding device 41, the setting position of the hair cutter 42 can be different.

[0062] As Figures 2 to 7As shown, the hair cutter 42 is located outside the winding device 41, and the driving motor 411 is connected with one end of the winding device 41 to drive the winding device 41 to rotate, so that the hair entering the air duct 40 is wound on the winding device 41, and the execution end 421 of the hair cutter 42 gradually approaches the support structure 412 on the winding device 41, so as to cut the hair.

[0063] Specifically, the cleaning process can refer to Figure 3 : the switch on the handle 60 drives the air suction source to suck the dirt on the surface to be cleaned, and the dirt moves along the air inlet side 45 of the air duct 40 through the suction nozzle 30; when the dirt contains long hair, the long hair is wound on the winding device 41, and when the thickness of the long hair exceeds the distance between the hair cutter 42 and the winding device 41, the long hair is cut into short hair by the cooperation between the hair cutter 42 and the winding device 41; the cut short hair enters the dirt recovery tank 20 along the air outlet side 46 of the air duct 40.

[0064] In another embodiment of the utility model not shown, the hair cutter 42 can also be selectively arranged on the winding device 41. The hair cutter 42 is arranged on the winding device 41 and located inside the winding device 41 to rotate with the winding device 41. The hair cutter 42 arranged inside the winding device 41 can realize the hair cutting process while the winding device 41 is winding the hair.

[0065] Specifically, the hair cutter 42 arranged inside the winding device 41 can facilitate assembly, reduce the occupied space, and make the structure of the hair processing device more compact. At this time, the hair cutter 42 can cut or iron the long hair, and the hair cutter 42 extends or retracts along its axial direction to realize the cutting of the long hair.

[0066] As shown in the figure Figures 6 to 8 , the hair cutter 42 cooperates with the winding device 41 to realize the friction cutting of the long hair, the execution end of the hair cutter 42 provides a friction surface 4211, and when the support structure 412 rotates to the friction surface 4211, the hair on the support structure 412 is pressed and rubbed between the friction surface 4211 and the support structure 412. The hair is cut by friction through the cooperation between the support structure 412 and the friction surface 4211. Thus, the elastic support 422 is in a compressed state, which can provide a driving force for the hair cutter 42 to ensure that the winding device 41 and the hair cutter 42 generate sufficient friction force, so that the long hair is ground into short hair.

[0067] Specifically, the execution end 421 is provided with a friction surface 4211 on the side facing the winding device 41, the friction surface 4211 is matched with the support structure 412, and the friction surface 4211 can cover the entire support structure 412, so as to facilitate the cutting of the hair on the support structure 412.

[0068] In the embodiment, in order to increase the contact area of the friction surface 4211 and the support structure 412, the friction surface 4211 is an arc surface, and the arc surface has an extending trend along the rotation direction of the winder 41. The friction surface 4211 is adapted to the length of the entire support structure 412, and the arrangement of the arc surface can increase the contact area of the friction surface 4211 and the hair, so as to improve the hair cutting effect. Thus, the concave arc surface can reserve a rotation space for the rotation of the support structure 412 of the winder 41, so that the entire rotation and friction process is more continuous and smooth.

[0069] As shown in Figures 6 to 7 In order to improve the hair cutting effect and adapt to the friction surface 4211, the support structure 412 includes a shaft 4121 and at least one blade 4122 fixed on the shaft 4121, and the blade 4122 extends along the direction of the shaft 4121. Thus, the blade structure occupies a smaller space of the air duct 40, and a larger space can be reserved for the air duct 40, so as not to affect the passing of other dirt in the air duct 40, so that the dirt is not easy to accumulate or even block at this position. Specifically, the blade 4122 is a plurality of blades, and the plurality of blades 4122 are arranged at intervals, and the bending directions of the plurality of blades 4122 are the same.

[0070] In the embodiment, the blade 4122 is an arc shape protruding in the rotation direction. Thus, the arc shape of the blade 4122 can cooperate with the arc shape of the execution end 421 of the hair cutter 42, so that the blade 4122 has a larger contact area with the execution end 421 of the hair cutter 42 during rotation, improving the grinding and cutting efficiency of long hair. It can be understood that the bending angle of the blade 4122 is the same as the bending angle of the friction surface 4211, so that the blade 4122 and the friction surface 4211 can obtain the maximum contact area when cooperating, and the hair can be subjected to a larger friction force, improving the hair cutting effect and efficiency.

[0071] In the embodiment, when the winder 41 rotates, the execution end 421 of the hair cutter 42 first abuts against the root position of the blade 4122 close to the shaft 4121, and the abutting position gradually moves to the end position of the blade 4122 away from the shaft 4121. Thus, the surface area of the side of the blade 4122 can be fully utilized, and more friction contact area can be provided within the same number of rotations of the winder 41, improving the hair cutting efficiency.

[0072] Specifically, the hair cutter 42 first extends into the space between the adjacent two blades 4122 and is arranged close to the shaft 4121. With the rotation of the winder 41, the hair cutter 42 slides on the blade 4122, and then the hair is cut.

[0076] As shown in Figures 2 to 3 The air duct 40 includes a sink portion 43 for accommodating the hair cutter 42, and the groove wall of the sink portion 43 has a communication opening 431, and the execution end 421 of the hair cutter 42 can extend into the inner cavity of the air duct 40 through the communication opening 431. By arranging the hair cutter 42 in the sink portion 43, the execution end 421 of the hair cutter 42 extends out of the communication opening 431, so that only the execution end 421 of the hair cutter 42 is arranged in the inner cavity, which facilitates fixing the position of the hair cutter 42, and ensures that the part of the hair cutter 42 located in the inner cavity can complete the effective cutting operation.

[0077] Specifically, the groove wall of the sink portion 43 close to the winder 41 is provided with the communication opening 431, and the execution end 421 of the hair cutter 42 extends into the inner cavity, which can ensure that the part of the hair cutter 42 contacting the hair is only the execution end 421, thereby avoiding the remaining part of the hair cutter 42 from contacting the hair and being wound by the hair.

[0078] As shown in Figure 2 The hair cutter 42 has a limiting portion 423, and the limiting portion 423 is stopped by the edge of the communication opening 431 to prevent the hair cutter 42 from being pulled out of the communication opening 431. By arranging the limiting portion 423 on the hair cutter 42, the hair cutter 42 is stopped by the edge of the communication opening 431, thereby avoiding the hair cutter 42 from being too long when extending into the inner cavity.

[0079] Specifically, the limiting portions 423 are two, and the two limiting portions 423 are respectively located on the two sides of the hair cutter 42, and the limiting portions 423 are protruding structures extending from the two sides of the hair cutter 42 in the width direction. The edges of the communication port 431 have stop grooves 432, the limiting portions 423 are accommodated in the stop grooves 432, and the length of the stop grooves 432 in the extension direction of the air duct 40 is greater than the length of the limiting portions 423, so that the limiting portions 423 can be close to or away from the winder 41 along the length direction of the stop grooves 432 in the stop grooves 432. The number of the stop grooves 432 and the number of the limiting portions 423 are the same and are one-to-one corresponding.

[0080] As shown in the drawings, Figures 1 to 3 The hair treatment device further comprises a cover plate 44, the cover plate 44 seals the slot of the sink portion 43 and is connected with the outer surface of the air duct 40. By arranging the cover plate 44, the position of the hair cutter 42 in the sink portion 43 can be checked in time, or the hair cutter 42 can be installed or replaced.

[0081] Specifically, the cover plate 44 is arranged at the slot of the sink portion 43, and the cover plate 44 is detachably connected with the air duct 40. Optionally, the cover plate 44 is connected with the air duct 40 through screws.

[0082] The utility model has the following beneficial effects: on the one hand, the brush roll 11 of the ground brush assembly 10 cleans the surface to be cleaned, the suction force generated by the vacuum suction source can suck the dirt on the surface to be cleaned into the suction nozzle 30, at the same time, the winder 41 in the air duct 40 starts to rotate under the driving of the driving motor 411, the long hair entering the air duct 40 can be captured by the rotating winder 41 and wound on the outer circumferential side of the support structure 412 of the winder 41, and other dirt such as sewage can be sucked into the dirt recovery tank 20. The long hair captured by the winder 41 is squeezed between the winder 41 and the hair cutter 42, when the winder 41 rotates, the support structure 412 rubs against the execution end of the hair cutter 42, the long hair squeezed between the winder 41 and the hair cutter 42 is ground by the friction force, so that the long hair becomes short hair, for example, the length of the ground short hair is between 2-4 cm. The shortened hair cannot be wound on the winder 41, and under the action of the vacuum suction source, the shortened hair is more easily collected by the collection equipment such as the sewage tank of the cleaning equipment, so that the air duct 40 of the cleaning equipment is not easily blocked, and the shortened hair is not easily agglomerated in the dirt recovery tank 20, the user can better clean the dirt recovery tank 20, and the dirt is not easy to block the drain pipe. On the other hand, the hair treatment device is arranged in the air duct 40, which can save the space of the ground brush assembly 10, effectively utilize the space of the scrubber, make the structure of the ground brush assembly 10 more compact, the winder 41 is driven to rotate by the motor, can timely capture and wind the long hair, and continuously process the long hair into short hair, the whole process is compact and efficient.
