Description

Technical Field

[0001] The present invention relates to a housing assembly, and in particular to a housing assembly for a floor brush mop. The housing assembly can not only accommodate a floor brush body, but also add a dirt cleaning layer to wipe the floor, wall, etc. The present invention also relates to a floor brush mop and a vacuum cleaner using the housing assembly. Background Art

[0002] As people's requirements for home cleanliness are increasing day by day, vacuum cleaners have gradually become one of the essential electrical appliances for furniture cleaning. The vacuum cleaner includes a mop head, a dust generating device and an air duct connected therebetween. A roller brush is arranged on the mop head, and the dust particles on the ground are lifted up by the rotation of the roller brush and collected by the dust generating device. However, the stains adhering to the ground cannot be cleaned by the roller brush. For this reason, some vacuum cleaners are currently equipped with a wiping function. For example, the vacuum cleaner suction head with a wiping cloth function disclosed in Patent 200820120065.X includes a suction head body, and a clamping mechanism for clamping a wiping cloth is arranged at the bottom of the suction head body on one side of the rotary brush, and the wiping cloth is clamped by the clamping mechanism. However, such a structure determines that the wipeable area is very small and the wiping effect is very limited. In addition, patent 201320739295.5 discloses an anti-collision multifunctional vacuum cleaner base, which includes a floor brush body with a rubber-coated part. A groove for a soft sheet to be pasted thereon is provided at the bottom of the floor brush body. By arranging Velcro on the groove, a rag that fits the shape and size of the groove is pasted to clean the floor, which is equivalent to the effect of cleaning with a rag by hand. The cloth can be removed and replaced at any time and then cleaned and recycled. Summary of the invention

[0003] The vacuum cleaner base in Patent 201320739295.5 can be equipped with a large rag, but in order to provide a large enough layout space for the rag, the vacuum cleaner base (equivalent to the floor brush mop) also needs to be set to a large volume to have space for arranging the rag, which not only increases the manufacturing cost, but also makes the vacuum cleaner base still fixed in a large and clumsy shape when it does not need to have the wiping function, which is not convenient for dragging and moving. In view of this, it is necessary to improve the layout of the rag to reduce the adverse effect of the addition of the rag on the volume of the floor brush mop, and.

[0004] In view of the shortcomings of the prior art, the present invention proposes a shell assembly for a floor brush mop, comprising an outer shell and an extension plate detachably connected to the outer shell, wherein the outer shell is used to accommodate a floor brush body; at least a portion of the extension plate extends beyond the projection area of ​​the outer shell, and an installation area for arranging a dirt cleaning layer is provided on the lower surface of the extension plate.

[0005] Wherein, a mounting area for arranging the dirt cleaning layer is provided on the lower surface of the extension plate, and the above feature defines that the extension plate is a main additional component for providing a mounting area for the dirt cleaning layer.

[0006] Among them, at least part of the expansion board extends outside the projection area of ​​the outer shell. The above features define the layout between the expansion board and the outer shell. For example, the entire expansion board and the outer shell may be arranged side by side so that the entire expansion board extends outside the projection area of ​​the outer shell; or a part of the expansion board and the outer shell may be overlapped up and down so that the part of the expansion board extends into the projection area of ​​the outer shell, while the other part of the expansion board extends outside the projection area of ​​the outer shell. Regardless of the layout method adopted, as long as part of the expansion board can extend outside the projection area of ​​the outer shell. In this way, the installation area can be set outside the projection area of ​​the outer shell, and the layout area of ​​the installation area is not limited by the volume of the outer shell, and the outer shell does not need to be deliberately set to a large volume in order to free up enough space to arrange the installation area.

[0007] According to the above technical solution, compared with the prior art, the beneficial technical effect of the present invention is that: by using the expansion board to provide an installation area for the dirt cleaning layer, the limitation of the setting of the dirt cleaning layer on the volume setting of the outer shell can be reduced, and the outer shell can be arranged in volume according to the needs of its internal functional components, without having to set a large volume in order to arrange a large area of ​​the dirt cleaning layer. In addition, since the expansion board is detachably connected to the outer shell, the expansion board can be installed when the dirt cleaning layer needs to be added, and the expansion board can be removed when the dirt cleaning layer is not needed, thereby reducing the total volume of the floor brush mop and facilitating flexible dragging of the floor brush mop.

[0008] A further technical solution may also be that a vertically arranged protruding column is provided on the expansion board, and a positioning hole adapted to the protruding column is also provided on the outer shell. When the expansion board is installed, the protruding column is detachably inserted into the positioning hole in a tight fit manner so that the expansion board can be detachably connected to the outer shell. Wherein, a vertically arranged protruding column is provided on the expansion board, and the above feature defines that the relationship between the protruding column and the board surface of the expansion board is not mutually balanced, and there is an angle of 80° or 90° between them. According to the above technical solution, the expansion board and the outer shell are connected together by the tight fit of the protruding column and the positioning hole, which not only facilitates the disassembly and assembly of the expansion board, but also optimizes the force transmission between the expansion board and the outer shell by means of the tight fit of the positioning hole and the protruding column, so that when the outer shell is dragged, the expansion board can be dragged together and moved to the correct position, that is, the wiping position of the expansion board can be accurately controlled by dragging the outer shell, and the loose fit between the expansion board and the outer shell is reduced. Secondly, when downward pressure is applied to the outer shell during the wiping process, the positioning hole and the raised column can be tightly fitted together to allow the dirt cleaning layer on the expansion plate to fit as closely as possible to the dirt to be cleaned without curling upward, which is beneficial to optimizing the wiping effect of the dirt cleaning layer.

[0009] A further technical solution may also include a plate-shaped tail plate extending from the outer shell, and the expansion plate may be detachably connected to the tail plate. In this way, the installation stability of the expansion plate may be enhanced by means of the tail plate.

[0010] A further technical solution may be that a raised rib plate is provided on the expansion board, one end of the rib plate is pressed against the outer shell, and the contact surface of the rib plate that contacts the outer shell has the same shape as the outer surface of the outer shell, and the rib plate is used not only to improve the mechanical properties of the expansion board but also to improve the bonding force between the expansion board and the outer shell. In this way, by using the rib plate, the dirt cleaning layer on the expansion board can be as close to the dirt to be cleaned as possible during the wiping process without being easily lifted up.

[0011] A further technical solution may be that at least two ribs are arranged in parallel on the expansion board, and when the expansion board is mounted on the outer shell, the ribs are arranged on the left and right sides of the tail board, which is conducive to balancing the bonding force between the expansion board and the outer shell.

[0012] A further technical solution may be that a roller group facing downward is further provided under the tail board, the roller group includes a roller and a roller frame for positioning the roller, the roller frame is connected to the tail board; a roller window for avoiding the roller is provided on the extension board, and when the extension board is mounted on the outer shell, the roller is arranged in the roller window. In this way, the sliding friction between the extension board and the dirt to be cleaned can be reduced by means of the roller.

[0013] In order to achieve a detachable connection between the expansion plate and the tail plate, one of the following buckling methods may be further selected:

[0014] In the first buckling mode, a protruding buckle is further provided on the extension plate, and the protruding buckle has a barb, and the protruding buckle is used to be buckled to the two sides of the tail plate to form a buckling connection between the extension plate and the tail plate.

[0015] In the second buckling mode, an elastic hook for forming a snap connection is further provided on the extension plate, and the elastic hook is used to snap into two sides of the tail plate to form an elastic snap connection between the extension plate and the tail plate.

[0016] According to the above two buckling methods, when the expansion board needs to be removed, the expansion board can be removed from the tail board by stepping down the expansion board with the foot and pulling up the outer shell, which is very convenient.

[0017] In addition, the present invention also proposes a floor brush mop using the shell assembly for the floor brush mop, characterized in that it includes the shell assembly for the floor brush mop and a floor brush body, a floor brush accommodating cavity capable of accommodating the floor brush body is formed in the shell body, and the floor brush body is arranged in the floor brush accommodating cavity.

[0018] The present invention also proposes a vacuum cleaner using the floor brush mop, characterized in that it includes the floor brush mop and a dust suction connecting pipe, the dust suction connecting pipe is connected to the floor brush accommodating chamber; it also includes a vacuum dust generating device for sucking dust, the vacuum dust generating device has an air inlet and an air outlet, the air inlet is connected to the pipe channel of the dust suction connecting pipe.

[0019] Since the present invention has the above characteristics and advantages, it can be applied to a housing assembly for a floor brush mop and the floor brush mop and vacuum cleaner used therein. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Combine the following Figure 2 to Figure 8The structure of the floor brush mop 300 is described in detail as shown. The floor brush mop 300 includes an outer shell 1, a floor brush assembly and a driving device. The outer shell 1 is formed with a floor brush accommodating chamber 10 and an auxiliary accommodating chamber 15 which are separated at the front and rear. A partition wall 12 is arranged between the auxiliary accommodating chamber 15 and the floor brush accommodating chamber 10. The floor brush assembly includes a floor brush body 2 and an end cover 14. The floor brush body 2 is rotatably arranged in the floor brush accommodating chamber 10. A lower opening portion 104 is arranged on the bottom wall of the floor brush accommodating chamber 10. The lower opening portion 104 is connected to the floor brush accommodating chamber 10, and part of the bristles of the floor brush body 2 pass through the lower opening portion 104 and extend out of the outer shell 1. The driving device includes a driving motor 3 and a transmission device 4. The driving motor 3 is arranged in the auxiliary accommodating chamber 15. The transmission device 4 includes a support seat 41, a driving transmission wheel 45 rotatably arranged at the rear end of the support seat 41, and a passive transmission wheel 44 rotatably arranged at the front end of the support seat 41, wherein the passive transmission wheel 44 is a belt pulley, and the active transmission wheel 45 is a belt pulley, and the passive transmission wheel 44 and the active transmission wheel 45 are connected by a belt 46 for speed reduction transmission. Of course, in other embodiments, the passive transmission wheel 44 can also be a transmission gear, and the active transmission wheel 45 can be a transmission gear, and the passive transmission wheel 44 and the active transmission wheel 45 are connected by speed reduction transmission. The active transmission wheel 45 and the drive motor 3 are arranged on the left and right sides of the support seat 41. In order to fix the drive motor 3, a motor connection hole 410 for connecting the drive motor 3 is provided on the support seat 41, and a screw passes through the motor connection hole 410 and is connected to the drive motor 3 so as to fix the drive motor 3 on the support seat 41. The output shaft of the drive motor 3 passes through the support seat 41 and is connected to the active transmission wheel 45 for speed reduction transmission. The passive transmission wheel 44 and the floor brush body 2 are arranged on the left and right sides of the support seat 41. A power output shaft 43 is arranged on the support seat 41. The power output shaft 43 is arranged on the left side of the floor brush accommodating chamber 15. One end of the power output shaft 43 is connected to the passive transmission wheel 44, and the other end is connected to the transmission wheel 47. The transmission wheel 47 and the passive transmission wheel 44 are arranged on the left and right sides of the support seat 41. The left end of the floor brush body 2 is connected to the transmission wheel 47, and is also connected to the power output shaft 43. The left side of the support seat 41 has a whirlpool space 19. The whirlpool space 19 and the floor brush accommodating chamber 10 are separated from each other by the support seat 41. The passive transmission wheel 44 and the active transmission wheel 45 are arranged in the whirlpool space 19. The support seat 41 also becomes the left side wall of the floor brush accommodating chamber 10.

[0044] like Figure 3 and Figure 4As shown, the outer shell 1 includes an upper shell 1a and a lower shell 1b that are detachably connected together, an upper shell slot 10a with an opening facing downward is provided on the upper shell 1a, and a lower shell slot 10b with an opening facing upward is provided on the lower shell 1b, and the upper and lower edges of the support seat 41 are respectively snapped into the upper shell slot 10a and the lower shell slot 10b. According to the above technical solution, since the active transmission wheel 45, the passive transmission wheel 44, and the drive motor 3 are all arranged on the support seat 41, the support seat 41 becomes the main support member of the active transmission wheel 45, the passive transmission wheel 44, and the drive motor 3 and integrates them into an independent functional module, so that they can be pre-installed before assembling the floor brush mop 300, simplifying the subsequent installation operation, and on this basis, when the upper and lower edges of the support seat 41 are respectively snapped into the upper shell slot 10a and the lower shell slot 10b and positioned, the active transmission wheel 45, the passive transmission wheel 44, and the drive motor 3 can be positioned at the same time. In addition, the method of fixing the support base 41 by means of the upper shell slot 10a and the lower shell slot 10b also facilitates the disassembly and assembly of the drive motor 3 and the transmission device 4.

[0045] like Figure 2 and Figure 3 As shown, a heat dissipation hole 17 is provided on the upper shell 1a corresponding to the position of the drive motor 3, and the heat dissipation hole 17 faces upward and is connected to the auxiliary accommodating chamber 15. A control circuit board 31 for controlling the drive motor 3 is also provided in the auxiliary accommodating chamber 15. The upper shell 1a includes a wall body that forms the floor brush accommodating chamber 10 and is arranged in an upward direction, and the wall body is a light-transmitting wall body. A light-transmitting lampshade 18 is also provided on the upper shell 1a, and a lighting lamp is provided in the light-transmitting lampshade 18, and the area in front of the floor brush mop 300 can be illuminated by the lighting lamp. An anti-collision strip 181 is also provided on the outer shell 1, and the anti-collision strip 181 is arranged below the light-transmitting lampshade 18.

[0046] like Figure 6 , Figure 7 , Fig. 9 and Fig.10As shown, the floor brush body 2 includes a skeleton 20 and a dirt cleaning layer 21 coated on the outside of the skeleton 20. The skeleton 20 includes a left connecting disk 22 and a right connecting disk 23 disposed at the left and right ends of the skeleton 20, and a connecting tube 24 connected between the left connecting disk 22 and the right connecting disk 23. The end cap 14 is disposed at the axial end position of the skeleton 20. The left connecting disk 22 has an axial concave cavity 220, and a second splicing tooth 221 protruding in the axial direction is disposed on the outer peripheral wall of the axial concave cavity 220, and several of the second splicing teeth 221 are arranged on an annular track. The transmission wheel 47 on the power output shaft 43 is axially protruding, and the first splicing tooth 471 is disposed on the protruding outer peripheral wall of the transmission wheel 47, and several of the first splicing teeth 471 are arranged on an annular track. The first splicing tooth 471 and the second splicing tooth 221 are used to realize the axial splicing transmission between the left end of the floor brush body 2 and the power output shaft 43. In this way, the left end of the floor brush body 2 can be axially automatically separated and transmission-connected to the power output shaft 43. When the floor brush body 2 is disassembled, the left end of the floor brush body 2 can be quickly separated from the power output shaft 43 when the floor brush body 2 is pulled out axially from left to right, and when installing, the floor brush body 2 is pushed axially from right to left, so that the left connecting disk 22 can quickly restore the axial plug-in transmission relationship with the transmission wheel 47.

[0047] like Figure 4 , Figure 6 and Fig.11As shown, the floor brush body 2 is arranged between the left side wall and the right side wall 13 of the floor brush accommodating chamber 10. In this embodiment, the support seat 41 becomes the left side wall of the floor brush accommodating chamber 10. A right side wall hole 130 is provided on the right side wall 13, and the end cover 14 can be detachably screwed on the right side wall hole 130 in a manner of self-rotation around its rotation axis O1. When the end cover 14 is screwed into the right side wall hole 130, the outer side surface of the end cover 14 is substantially flush with the outer side surface of the right side wall 13 of the outer shell 1. Of course, in other embodiments, the end cover 14 can also be detachably positioned on the right side wall 13 by a buckle connection. The right end of the floor brush body 2 is radially rotatably arranged on the end cover 14 so that when the end cover 14 is screwed on the right side wall 13, the end cover 14 not only blocks the right side wall hole 130 but also supports the right end of the floor brush body 2. An axial retaining structure is provided between the right end of the floor brush body 2 and the end cover 14. The axial retaining mechanism is used to allow the end cover 14 to move axially with the floor brush body 2 after the end cover 14 is released from its position, so that the floor brush body 2 can be separated from the left side wall and axially move through the right side wall hole 130 to leave the floor brush accommodating chamber 10. The axial retaining mechanism includes a support shaft 5 connected between the floor brush body 2 and the end cover 14. The support shaft 5 extends axially and its left end is connected to the right connecting plate 23 of the floor brush body 2. The right end of the support shaft 5 is provided with an anti-slip head 52. An axially extending avoidance cavity 1424 is provided on the end cover. The anti-slip head 52 is used to be arranged in the avoidance cavity 1424 so that the end cover 14 can float axially relative to the skeleton 20 but keep the end cover 14 associated with the skeleton 20. The anti-slip head 52 is T-shaped and has a transverse head 521 and a vertical rod 522 . The outer diameter of the transverse head 521 is greater than the outer diameter of the vertical rod 522 .

[0048] like Fig.11 , Fig.12 and Fig.13As shown, the end cover 14 includes an end cover body 141 and an end cover panel 142. The end cover body 141 is bowl-shaped and has a bowl inner cavity 1410. The end cover panel 142 is detachably connected to the bowl inner cavity 1410 of the end cover body. A pair of vertical walls (1413, 1414) arranged front and back are arranged in the bowl inner cavity 1410. A clamping cavity 1415 is formed between the pair of vertical walls (1413, 1414). A pair of left and right recesses (1411, 1412) arranged left and right are arranged on the outer surface of the bowl inner cavity 1410 corresponding to the clamping cavity 1415. A pair of handle body clamping arms (1422, 1422a) are arranged on the inner side wall of the end cover panel 142. The pair of handle body clamping arms (1422, 1422a) are arranged at the left and right ends of the end cover panel 142. A pair of handle body clamping arms (1422, 1422a) are respectively clamped on the left and right pits (1411, 1412), so that the left and right ends of the end cover panel 142 are respectively detachably clamped on the left and right pits (1411, 1412). A pair of sleeve arms (1423, 1423a) are also provided on the inner side of the end cover panel 142, and the pair of sleeve arms (1423, 1423a) are arranged between the pair of handle body clamping arms (1422, 1422a). The avoidance cavity 1424 is formed between the pair of sleeve arms (1423, 1423a). The avoidance cavity 1424 is hidden in the bowl inner cavity 1410 and is provided on the end cover panel 142. An annular head (1426, 1426a) is provided on the sleeve arm (1423, 1423a), and a sleeve ring hole 1425 for sleeve-fitting the vertical rod portion 522 of the support shaft 5 is formed between the pair of annular heads (1426, 1426a), and the outer diameter of the sleeve ring hole 1425 is larger than the outer diameter of the vertical rod portion 522 of the support shaft 5 and smaller than the outer diameter of the transverse head 521. The vertical rod portion 522 is sleeved in the sleeve ring hole 1425, and the transverse head 521 is located in the avoidance cavity 1424. In this way, the right end of the support shaft 5 is axially flexibly connected to the end cover 14. During assembly, the left end of the support shaft 5 is first connected to the right connecting disk 23 or even fixed to the right connecting disk 23 by secondary injection molding, and the end cover panel 142 is clamped on the end cover body 141, and then the anti-slip head 52 is inserted through the end cover body 141 into the avoidance cavity 1424, and the installation operation is very convenient. In addition, the bowl inner cavity 1410 of the end cover body 141 can be fully utilized to store the avoidance cavity 1424, making the structure of the floor brush assembly more compact. Furthermore, a bearing 51 is provided on the end cover body 141, and the inner diameter of the inner ring of the bearing 51 is larger than the transverse head 521, and the transverse head 521 can axially pass through the bearing 51 and the end cover body 141 and be inserted into the avoidance cavity 1424.This can further facilitate the installation operation between the support shaft 5 and the end cover 14 .

[0049] like Fig.11 As shown, it also includes a driving element 54, and the driving element 54 is used to allow at least part of the end cover 14 to automatically emerge from the right side wall hole 130 when the end cover 14 is released from its position, so as to facilitate holding the end cover 14. In this embodiment, the driving element 54 is a reset spring sleeved on the support shaft 5, and a washer 53 is also sleeved on the support shaft 5, and the washer 53 is arranged on the right connecting disk 23. The two ends of the reset spring respectively press between the washer 53 and the inner ring of the bearing 51. The use of the washer 53 and the bearing 51 can prevent the reset spring from directly pressing and crushing the right connecting disk 23 and the end cover 14. In addition, the structure in which the reset spring is sleeved on the support shaft 5 can not only use the support shaft 5 to position the reset spring, but also make the structure of the floor brush assembly more compact. According to the above technical solution, when the end cover 14 is positioned on the right side wall 13, the return spring is compressed and deformed to store energy. When the end cover 14 is released from its position, the return spring stretches and deforms to release potential energy and pushes the end cover 14 to move axially and emerge from the right side wall hole 130. In addition, by utilizing the avoidance cavity 1424, the return spring does not need to drive the floor brush body 2 to move axially together in the process of driving the end cover 14 to automatically emerge from the right side wall hole 130, thereby reducing the load on the return spring. In this way, before the end cover 14 is axially pulled out by hand, the drive element 54 can allow the end cover 14 to emerge from the right side wall hole 130 in advance, that is, the area of ​​the end cover 14 exposed outside the right side wall hole 130 that can be held by the hand is increased, so that the hand can hold more of the end cover 14, thereby facilitating the application of axial extraction force to the end cover 14.

[0050] In other embodiments, the driving element may also be other types of elastic members such as elastic arms or silicone columns, and may be applied to the end cap 14 and the right side wall 13 by top pressure. Alternatively, the driving element may be a pair of magnetic members, which generate mutually repelling magnetic forces when the pair of magnetic members are close to each other, and the pair of magnetic members are disposed on the end cap 14 and the right end of the floor brush body 2, or on the end cap 14 and the right side wall 13. Among them, a pair of magnetic members may both be hard magnets, or one of them may be a hard magnet and the other may be a soft magnet. When the end cap 14 is positioned on the right side wall, a mutually repelling magnetic force is generated between the pair of magnetic members, and when the end cap 14 is released from its position, the magnetic member disposed on the end cap 14 is subjected to the magnetic force and moves axially with the end cap 14 to emerge from the right side wall hole 130.

[0051] like Fig.11 As shown, a first sleeve 231 is provided on the right connecting plate 23, and the first sleeve 231 is axially extended in the direction of the end cover 14. A second sleeve 1416 is provided on the end cover 14, and the second sleeve 1416 is axially extended in the direction of the right connecting plate 23. The first sleeve 231 and the second sleeve 1416 are sleeved together. In this way, when the floor brush assembly is lifted by holding the end cover 14, the first sleeve 231 and the second sleeve 1416 can be used to cooperate with the support shaft 5 to share the weight of the floor brush body 2, so as to avoid the support shaft 5 being bent and deformed by the pull and affecting the use.

[0052] The floor brush mop 300 adopts a side-pull-out roller brush disassembly and assembly structure. In order to be able to put in or extract the floor brush body 2, the inner diameter of the right side wall hole 130 cannot be too small to affect the passage of the floor brush body 2. In order to allow the floor brush body 2 to contact the ground during use, the rotation axis O2 of the floor brush body 2 needs to be set as close to the ground as possible, but this will also cause the lower side wall of the right side wall hole 130 to be too thin and the structural strength is insufficient, which is very easy to be damaged. In order to solve the above technical problems, Fig. 9 As shown, the right end of the floor brush body 2 is connected to the end cover 14 through the support shaft 5, so that the floor brush joint point A formed on the end cover 14 is arranged in a staggered manner with the rotation axis O1 of the end cover 14, so that when the end cover 14 is screwed on the right side wall hole 130, the end cover 14 can drive the right end of the floor brush body 2 to revolve around the rotation axis O1 of the end cover 14 and allow part of the bristles of the floor brush body 2 to pass through the lower opening 104 and extend out of the outer shell 1. In this way, compared with the method of setting the floor brush joint point A on the rotation axis O1 of the end cover 14, part of the bristles of the floor brush body 2 can be arranged downward as much as possible and pass through the lower opening 104 to extend out of the outer shell 1, so that more space for setting the thickness of the lower hole wall of the right side wall hole 130 can be reserved. Further, the rotation axis of the power output shaft 43 is arranged in a staggered manner with the rotation axis O1 of the end cover 14. This helps to balance the rotation axis of the floor brush body 2 installed in the floor brush accommodating cavity 10 with the ground. In addition, the central axis O2 of the support shaft 5 overlaps with the central axis of the floor brush body 2 but is offset from the rotation axis O1 of the end cap 14 .

[0057] like Fig.18 and Fig.19 As shown, the floor brush mop 300 also includes a tail plate 6 and an extension plate 7, and the tail plate 6, the extension plate 7 and the outer shell 1 constitute the outer shell assembly for the floor brush mop. The tail plate 6 extends from the outer shell 1 and is in the shape of a plate. The tail plate 6 is connected to the outer shell 1 and is located below the first jacket 101. The tail plate 6 and the outer shell 1 are an integrally formed structure. The tail plate 6 is provided with a groove 60 into which the first jacket 101 can sink. A roller group 61 facing downward is also provided below the tail plate 6. The roller group 61 includes a roller and a roller frame for positioning the roller, and the roller frame is connected to the tail plate 6.

[0058] like Fig. 20 and Fig.21 As shown, the expansion board 7 is detachably connected to the outer shell 1 and the tail plate 6. The specific structure is as follows: the expansion board 7 is in the shape of a plate, and a vertically arranged protruding column 71 is provided on the expansion board 7. A positioning hole 16 adapted to the protruding column 71 is also provided on the outer shell 1. When the expansion board 7 is installed, the protruding column 71 is detachably inserted into the positioning hole 16 in a tight fit manner so that the expansion board 7 can be detachably connected to the outer shell 1. At least two ribs 72 arranged in parallel on the left and right are also provided on the expansion board 7. In this embodiment, four ribs 72 are provided. One end of the rib 72 is against the outer shell 1, and the contact surface of the rib 72 in contact with the outer shell 1 has the same shape as the outer shape of the outer shell 1. The rib 72 is used not only to improve the mechanical properties of the expansion board 7 but also to improve the bonding force between the expansion board 7 and the outer shell 1. The expansion plate 7 is also provided with raised buckles (73, 73a), and the raised buckles (73, 73a) have barbs, and the raised buckles (73, 73a) are used to snap onto the two sides of the tail plate 6 to form a snap connection between the expansion plate 7 and the tail plate 6. In other embodiments, the expansion plate 7 may also be provided with elastic snap hooks for forming a snap connection, and the elastic snap hooks are used to snap onto the two sides of the tail plate 6 to form an elastic snap connection between the expansion plate 7 and the tail plate 6. The expansion plate 7 is provided with a roller window 74 for avoiding the roller. When the expansion plate 7 is installed on the outer shell 1, the four ribs 72 are arranged on both sides of the tail plate 6, and the rollers are arranged in the roller windows 74 to reduce the sliding friction between the expansion plate 7 and the cleaning surface. A portion of the extension plate 7 extends into the projection area of ​​the outer shell 1, while the other portion of the extension plate 7 extends out of the projection area of ​​the outer shell 1. A mounting area 70 for arranging a dirt cleaning layer (not shown) is provided on the lower surface of the extension plate 7. The dirt cleaning layer arranged on the mounting area 70 is also located below the tail plate 6 and arranged in a downward direction. Of course, in other embodiments, the entire extension plate 7 can also be extended out of the projection area of ​​the outer shell 1.

[0059] According to the above technical solution, the expansion plate 7 is used to provide the installation area 70 for the dirt cleaning layer, which can reduce the limitation of the volume setting of the outer shell 1 due to the setting of the dirt cleaning layer. The outer shell 1 can be arranged in volume according to the needs of its internal functional components, without having to set a large volume in order to arrange a large area of ​​the dirt cleaning layer. In addition, since the expansion plate 7 is detachably connected to the outer shell 1, the expansion plate 7 can be removed when the dirt cleaning layer is not needed, thereby reducing the total volume of the floor brush mop 300 and facilitating flexible dragging of the floor brush mop 300. In addition, since the extension plate 7 is provided with a vertically arranged protruding column 71, the protruding column 71 is arranged to extend upwardly and is substantially perpendicular to the extension plate 7, and the outer shell 1 is provided with a positioning hole 16, the extension plate 7 and the outer shell 1 are connected together through the tight fit of the protruding column 71 and the positioning hole 16, which not only facilitates the disassembly and assembly of the extension plate 7, but also optimizes the force transmission between the extension plate 7 and the outer shell 1 by means of the tight fit of the positioning hole 16 and the protruding column 71, so that when the outer shell 1 is dragged, the extension plate 7 can be dragged together and moved to the correct position, that is, the wiping position of the extension plate 7 can be accurately controlled by dragging the outer shell 1. Secondly, during the wiping process, when downward pressure is applied to the outer shell 1, the dirt cleaning layer on the extension plate 7 can be as close to the dirt to be cleaned as possible without curling up through the cooperation of the positioning hole 16 and the protruding column 71, which is conducive to optimizing the wiping effect of the dirt cleaning layer.
