[0078] The solution of this application will be described in detail below with reference to the accompanying drawings.

[0079] As analyzed in the background technology of this application, the existing floor scrubbers have a short standby time and make a lot of noise. In order to solve the above technical problems, this application provides a cleaning roller.

[0080] Example 1:

[0081] like Figures 1 to 9As shown, a cleaning roller assembly 100 is installed in the cleaning head shell 401 of the floor scrubber cleaning head 40, and the cleaning roller assembly 100 is sleeved on a motor assembly 1 installed on the first side wall of the cleaning head shell at one end, and the motor assembly 1 has an output shaft 1b, and a brush assembly (not shown in the drawings) is also connected between the two pairs of side walls (402, 403) of the cleaning head shell 401. The cleaning roller assembly 100 includes a roller assembly 10 and an end button assembly (12, 3), and the roller assembly 10 includes an inner cylinder 101 and an outer cylinder 102 formed on the outer surface of the inner cylinder for scrubbing the surface to be cleaned. The output shaft 1b is coupled to drive one end of the inner wall of the inner cylinder 101, thereby synchronously driving the roller assembly 10 to rotate; the end button assembly 12 and the brush assembly are coupled to rotate synchronously through a transmission assembly 20 arranged on the cleaning head shell; wherein, the roller assembly 10 and the end button assembly 12 rotate synchronously.

[0082] Specifically, such as Figures 1 to 7 As shown, the cleaning roller assembly 100 is installed in the cleaning head housing 401 of the floor scrubber cleaning head 40, and the motor assembly 1 is fixed to the first side wall 402 of the cleaning head housing 401 by the motor fixing portion 1f. Figure 6 、 Figure 7 As shown, the motor assembly 1 includes a motor 1A that provides power to the cleaning roller 100 and can drive the output shaft 1b to rotate, a thermally conductive protective tube 1g, a hinge (not marked in the drawings), a motor fixing part 1f, and a hinge pin 1e for hingedly connecting the motor fixing part 1f and the hinge, wherein the thermally conductive protective tube 1g seals the hinge, the motor 1A, and the hinge in sequence in the hollow cavity of the thermally conductive protective tube 1g, the output shaft 1b rotates under the drive of the motor 1A, and is coupled to the coupling part 1011 of the inner tube 101 to rotate, the end button assembly 12 is engaged with the inner tube 101 so as to rotate synchronously, and the end button assembly 12 then drives the transmission assembly 20 to realize the synchronous rotation of the brush assembly. A first bearing M is sleeved on the outer edge of one end of the hinge of the motor assembly 1 close to the motor 1A, and the outer ring of the first bearing M is sleeved on the inner wall of the inner cylinder 101 corresponding to the end of the hinge of the motor assembly 1 close to the motor 1A. The inner cylinder 101 rotates under the drive of the motor 1A of the motor assembly 1, so that the first bearing M can provide rotatable and stable support for the inner cylinder 101 at the support point of the hinge, so that the roller assembly 10 of the cleaning roller assembly 100 can rotate more smoothly.

[0083] Specifically, the outer cylinder 102 is formed by foaming PVA (Polyvinyl alcoho, English abbreviation: PVA, chemical name: polyvinyl alcohol) on the outer surface of the inner cylinder 101.

[0084] The beneficial effects of the utility model are as follows: the cleaning roller assembly 100 is sleeved on the motor assembly 1 installed on a side plate of the cleaning head housing 401, the cleaning roller assembly 100 includes a roller assembly 10 and a terminal assembly (12, 3), the roller assembly 10 includes an inner cylinder 101 and an outer cylinder 102, the output shaft 1b of the motor assembly 1 is coupled to drive one end of the inner wall of the inner cylinder 101, thereby synchronously driving the roller assembly 10 to rotate, the roller assembly 10 and the terminal assembly (12, 3) to rotate synchronously, and the terminal assembly (12, 3) and the brush assembly are coupled to rotate synchronously through the transmission assembly 20 provided on the cleaning head housing. The motor 1A of the motor assembly 1 can only drive the roller assembly 10 to rotate, while the brush assembly can be synchronously rotated with the roller assembly 10 through the transmission assembly 20, thereby improving the standby time of the floor scrubber without increasing the volume of the floor scrubber, and at the same time reducing the noise of the floor scrubber in the working state.

[0085] In some embodiments, as Figure 3 、 Figure 6 As shown, the terminal assembly 12 is detachably connected to the first gear 121, and the transmission assembly 20 includes the first gear 121 and a second gear 201 in transmission connection with the first gear 121. The second gear 201 is in transmission connection with the brush assembly. Through the transmission function of the transmission assembly 20, the power of the motor 1A built into the motor assembly 1 to which the cleaning roller 100 is sleeved can be moved a certain distance in a direction parallel to the axis of the motor 1A so as to transmit the rotational power to the brush assembly, thereby eliminating the need for an additional motor to provide power to the brush assembly, reducing the power consumption of the floor scrubber and reducing the noise of the floor scrubber.

[0086] It should be noted that the transmission component 20 mentioned here is not limited to the form of mutual transmission between the first gear 121 and the second gear 201. For example, two first wheels and second wheels that can rotate by friction with each other, two first wheels and second wheels that do not rub against each other but can rotate synchronously through their respective magnetism, and two first wheels and second wheels that do not rub against each other but can be connected and rotated with each other through belts, racks, chains, etc. These methods are all within the protection scope of the transmission component of the present application. Those skilled in the art can make adaptive adjustments to the details of the specific implementation based on the present application, and they will not be elaborated here.

[0087] In some embodiments, as Figure 3 、 Figure 5 、 Figure 6As shown, the terminal button assembly 12 includes an input end (not marked in the drawings) and a clamping end (not marked in the drawings), the input end is coupled with the output shaft 1b of the motor 1A, a part of the outer edge of the end of the clamping end is engaged with the first gear 121, and a part of the outer edge of the clamping end is clamped with the second side wall 403 of the cleaning head housing 401, and the terminal button assembly 12 has a movable stroke along the axial direction of the motor 1A. The terminal button assembly 12 is socketed with the first gear 121, and can transmit power to the first gear 121, thereby further allowing the transmission assembly 20 to transmit power to the brush assembly. The terminal button assembly 12 has an axial movable stroke along the motor 1A, which allows the user to quickly remove the roller assembly 10 socketed on the motor drive assembly 1 when maintenance of the motor drive assembly 1 is required. After pressing the terminal button assembly 12, the terminal button assembly 12 can be allowed to leave the second side wall 403 of the cleaning head shell 401, and then the cleaning roller assembly 100 is rotated so that its free end completely leaves the second side wall 403, and then the roller assembly 10 is pulled out, and the motor drive assembly 1 can be further maintained.

[0088] Specifically, such as Figure 3 、 Figure 5 、 Figure 6 As shown, the output shaft 1b rotates under the drive of the motor 1A and is coupled to the coupling part 1011 of the inner cylinder 101 to rotate. The end button assembly 12 is engaged with the inner cylinder 101 and rotates synchronously. The end button assembly 12 then drives the transmission assembly 20 to realize the synchronous rotation of the brush assembly.

[0089] In some embodiments, as Figure 3 、 Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 As shown, the end button assembly 12 is coupled to one end of the inner wall of the inner cylinder 101, and the end button assembly 12 rotates synchronously with the rotation of the roller assembly 10. The end button assembly 12 rotates synchronously with the roller assembly 10, which can conveniently allow the motor 1A of the motor drive assembly 1 to transmit power to the end button assembly 12, and further allow the transmission assembly 20 to transmit power to the brush assembly.

[0090] Specifically, Figure 5 As shown, the output shaft 1b rotates under the drive of the motor 1A, and the output shaft 1b drives the coupling (not marked in the drawing) fixedly connected to it to rotate, the coupling coupling 1011 of the inner cylinder 101 rotates, and the end button assembly 12 is engaged with the inner cylinder 101 so as to rotate synchronously.

[0091] The cleaning roller assembly 100 provided by the present invention has an output shaft 1b that is coupled to drive one end of the inner wall of the inner cylinder 101 of the roller assembly 10 under the drive of the motor 1A, thereby synchronously driving the roller assembly 10 to rotate. Its end button assembly 12 has an axial movable stroke along the motor 1A, so that when the cleaning roller 100 needs to repair and disassemble the motor 1A of the motor drive assembly 1, it only needs to press the end button assembly 12 to pull the roller assembly 10 out from the motor assembly 1, and then further disassemble and install the motor 1A. It is more convenient to repair and disassemble the drive motor sleeved in the cleaning roller assembly 100.

[0092] In some embodiments, as Figure 3 The transmission assembly 20 further includes a third gear 302 that is detachably fixedly connected to the brush body 301 of the brush assembly, and the third gear 302 is in transmission connection with the second gear 201. The motor 1A of the motor drive assembly 1 transmits power to the terminal assembly (12, 3), the first gear 121 is sleeved on one end of the terminal assembly (12, 3), and transmits power to the first gear 121. The first gear 121 is in transmission connection with the second gear 201, and the third gear 302 is in transmission connection with the second gear 201. The third gear 302 is detachably fixedly connected to the brush body 301 to form a brush assembly, thereby, the motor 1A of the motor drive assembly 1 transmits power to the brush assembly through the transmission assembly 20.

[0093] In some embodiments, as Figure 5 、 Figure 6 、 Figures 10 to 12 As shown, the end button assembly 12 includes a first gear 121 and an elastic member 122; the first gear 121 is sleeved on one end of the elastic member 122, and the elastic member 122 is detachably fixedly connected to the roller assembly 10 within the inner cavity of the roller assembly 10. The first gear 121 is sleeved on one end of the end button assembly 12 to facilitate the transmission of power to the first gear 121. The elastic member 122 is detachably fixedly connected to the roller assembly 10 within the inner cavity of the roller assembly 10, facilitating the coupling of the roller assembly 10 with the coupling driven by the output shaft 1b via the coupling portion 1011 on the inner cylinder 101, thereby transmitting power from the roller assembly to the end button assembly 12, and then from the end button assembly 12 to the first gear 121.

[0094] Specifically, such as Figure 5 、 Figure 6 As shown, the end button assembly 12 includes a first gear 121 and an elastic member 122 ; the first gear 121 is sleeved on one end of the elastic member 122 , and the elastic member 122 is detachably fixedly connected to the drum assembly 10 in the inner cavity of the drum assembly 10 .

[0095] In some embodiments, as Figure 5 、 Figure 6As shown, the elastic member 122 includes a rotating shaft 1221, a spring 1222 and a sleeve 120; the sleeve 120 is provided with a central shaft hole (not marked in the drawing) with a large and a small opening at both ends (not marked in the drawing), one end of the rotating shaft 1221 passes through the central shaft hole of the sleeve 120, and a first stop member 12211 is provided on the outside of the other end of the rotating shaft 1221. The spring 1222 is sleeved on the rotating shaft 1221 and is located on the side of the first stop member 12211 away from the first gear 121, and one end of the spring 1222 abuts against the small open end of the sleeve 120. The sleeve 120 is provided with a large and a small opening at both ends and a central shaft hole passing through the two openings, so that one end of the rotating shaft 1221 can pass through the central shaft hole of the sleeve 120. The spring 1222 is sleeved on the rotating shaft 1221, and one end of the spring 1222 abuts against the inner wall of the small opening end of the sleeve 120, and the other end of the spring 1222 abuts against the other end of the elastic member 122. When external force is applied to the elastic member 122, the outer end of the elastic member 122 compresses the spring 1222, and at the same time, one end of the rotating shaft 1221 passes through the central shaft hole along its axis under the joint action of external force and the elastic force of the spring 1222, so that the end button assembly 12 has a movable stroke along the axial direction of the motor 1A.

[0096] In some embodiments, as Figure 5 、 Figure 6 As shown, the end of the rotating shaft 1221 is fixedly connected to an end cap 1223, and the end cap 1223 is sleeved on the side of the first stop member 12211 close to the first gear 121, and abuts against the roller assembly 10 in the inner cavity of the roller assembly 10. The maximum diameter end of the end cap 1223 closes the large open end of the sleeve 120, and the other end of the end cap 1223 passes through the first gear 121.

[0097] Specifically, such as Figures 3 to 8 As shown, the outer edge of the end cap 1223 away from the sleeve 120 is cylindrical, and the inner ring of the first gear 121 is cylindrical. The cylindrical outer edge of the end cap 1223 away from the sleeve 120 and the cylindrical inner ring of the first gear 121 are transitionally matched. When the roller assembly 10 is driven by the motor drive assembly 1, the end button assembly 12 is driven to rotate, thereby driving the first gear 121 to rotate. It should be noted that the outer edge of the end cap 1223 away from the sleeve 120 is set to a cylindrical shape only to improve the convenience of matching the outer edge of the end cap 1223 and the inner ring of the first gear 121. Correspondingly, the outer edge of the end cap 1223 away from the sleeve 120 can be set to a polygonal prism shape, and the inner ring of the first gear 121 can also be set to a polygonal prism shape, as long as the two can form a transitional fit and can drive each other to rotate synchronously. This application does not specifically limit the shape of the outer edge of the end cap 1223 and the shape of the inner ring of the first gear 121.

[0098] It should also be noted that the shape of the rotating shaft 1221 can be cylindrical, polygonal, or any other long column with a regular cross-section, and the first stopper 12211 can be a stepped column of the rotating shaft 1221. This application does not specifically limit the shape of the rotating shaft 1221 or the first stopper 12211. As long as the end cap 1223 can be fixedly connected to one end of the rotating shaft 1221, the first stopper 12211 can resist the end cap 1223 and the shaft cover 1224, and the spring 1222 can be freely extended and retracted around the outer periphery of the rotating shaft 1221, any deformation or adjustment of the functional components based on the concept of this application is within the scope of protection of this application.

[0099] In some embodiments, as Figures 5 to 8 As shown, the end cap 1223 is provided with a second stopper 12231 on the outer edge wall of one end side of the first gear 121, and a first copper sleeve 1225 is provided between the first gear 121 and the second stopper 12231. The first copper sleeve 1225 is fixed on the inner layer 4031 of the second side wall during the injection molding process of the cleaning head shell 401. In order to prevent the transition fit between the cylindrical outer edge of the end cap 1223 away from the sleeve 120 and the cylindrical inner ring of the first gear 121 from slipping against each other when the resistance is too large, resulting in the inability to transmit power to the brush assembly, the second stopper 12231 is a gear ring extending around the outer edge of the end cap 1223 close to the sleeve 120 in the direction away from the sleeve 120, and the corresponding first gear 121 and the second stopper 12231 are matched with a tooth groove on the side, and the gear ring of the second stopper 12231 engages with the tooth groove of the first gear 121, so that even when the inner ring of the first gear 121 and the outer edge of the end cap 1223 away from the sleeve 120 slip, power transmission can still be achieved by the mutual engagement of the gear ring tooth grooves. The first copper sleeve 1225 is fixed on the second side wall inner layer 4031 during the injection molding process of the cleaning head shell 401, which can ensure a higher coaxiality of the first copper sleeve 1225 and the corresponding coupling holes of the cleaning head shell 401, and can reduce the wear between the outer edge of the end cap 1223 away from the shaft sleeve 120 and the first copper sleeve 1225.

[0100] In some embodiments, as Figures 5 to 8As shown, a second copper sleeve 1227 is provided on the side of the first gear 121 away from the second stopper 12231. The second copper sleeve 1227 is fixed to the second sidewall outer layer 4032. During operation, the first gear 121 is confined between the first copper sleeve 1225 and the second copper sleeve 1227. Of course, the second copper sleeve 1227 can be fixed to the second sidewall outer layer 4032 during the injection molding process of the second sidewall outer layer 4032. This ensures a higher degree of coaxiality between the second copper sleeve 1227 and the corresponding engaging holes of the second sidewall outer layer 4032, thereby reducing wear between the first gear 121 and the second copper sleeve 1227.

[0101] In some embodiments, as Figures 5 to 8 As shown, a transmission assembly cover plate 4033 for covering the transmission assembly 20 is also provided on the second sidewall inner layer 4031. Accordingly, a mating through hole is provided on the second sidewall outer layer 4032 that matches the shape of the transmission assembly cover plate 4033. After the transmission assembly cover plate 4033 is placed on the second sidewall inner layer 4031 and then on the second sidewall outer layer 4032, a complete second sidewall 403 is formed. The second copper sleeve 1227 is secured to the transmission assembly cover plate 4033. During operation, the first gear 121 is trapped between the first copper sleeve 1225 and the second copper sleeve 1227. Of course, the second copper sleeve 1227 can be secured to the transmission assembly cover plate 4033 during the injection molding process. This ensures higher coaxiality between the corresponding mating holes of the second copper sleeve 1227 and the transmission assembly cover plate 4033, thereby reducing wear between the first gear 121 and the second copper sleeve 1227.

[0102] In some embodiments, as Figures 5 to 8As shown, a removable shaft cover 1224 is sleeved on one end of the rotating shaft 1221 near the first gear 121. The shaft cover 1224 is removably fixed to the large opening end inside the shaft sleeve 120, and the other end of the spring 1222 abuts against the shaft cover 1224. A through hole (not shown) is provided in the center of the shaft cover 1224. A recess (not shown) is provided in the middle of the rotating shaft 1221 near the end cap 1233 and fits into the through hole. The shaft cover 1224 is provided with mounting holes (not shown) around the circumference of the rotating shaft 1221 for connection to the large opening end of the shaft sleeve 120. Screws are tightened in these mounting holes to secure the shaft cover 1224 to the large opening end of the shaft sleeve 120. When the entire end button assembly 12 needs to be removed for maintenance, the end cap 1223 is grasped and pulled away from the outer edge of the shaft sleeve 120. The end cap 1223 drives the rotating shaft 1221. The protrusion at the concave end of the rotating shaft 1221 drives the shaft cover 1224 outward. The shaft cover 1224 then drives the shaft sleeve 120 outward, and finally the entire end button assembly 12 can be separated from the roller assembly 10. After the end button assembly 12 is removed from the cleaning roller 100, further maintenance can be performed on the end button assembly 12.

[0103] Example 2:

[0104] This series of embodiments differs from the aforementioned embodiments mainly in the specific structure of the end button assembly 3 and whether the end button assembly 3 drives the roller assembly 10 to rotate. The parts that are the same as the technical solutions of the aforementioned embodiments will not be repeated here.

[0105] like Figures 10 to 12 、 Figure 15 As shown, the motor assembly 1 includes a motor 1A for providing power to the cleaning roller assembly 100, a reduction gear 1a coupled to the output end of the motor 1A, an output shaft 1b driven to rotate by the reduction gear 1a, an output end sealing plug 1c sleeved on the outer edge of the output shaft 1b, a terminal button mounting seat 1d sleeved on the outer edge end of the output shaft 1b, a heat-conducting protective tube 1g, a hinge (not shown in the drawings), a motor fixing portion 1f, and a hinge pin 1e for hingedly connecting the motor fixing portion 1f and the hinge, wherein the heat-conducting protective tube 1g connects the hinge, the motor, and the hinge. The machine 1A, the reduction gear 1a, the output end sealing plug 1c, and the terminal button mounting seat 1d are sealed and sleeved in the hollow cavity of the thermal protective tube 1g in sequence. The end of the output shaft 1b is fixedly connected to the terminal button body 32. The outer edge of the terminal button body 32 is provided with a clamping portion 321. The output shaft 1b rotates under the drive of the motor 1A and drives the terminal button body 32 to rotate. The terminal button body 32 is coupled to the inner cylinder 101 through the clamping portion 321 and drives the inner cylinder 101 to rotate. At the same time, the terminal button assembly 3 drives the transmission assembly 20 to realize the synchronous rotation of the brush assembly.

[0106] In some embodiments, as Figure 10、 Figure 11 As shown, the end of the output shaft 1b is fixedly connected to the end button body 32. The outer edge of the end button body 32 is provided with a clamping portion 321. Driven by the motor 1A, the output shaft 1b rotates and drives the end button body 32 to rotate. The end button assembly 3 is also driven by the motor 1A to rotate. The end button body 32 of the end button assembly 3 is coupled to the inner cylinder 101 through the clamping portion 321 and drives the inner cylinder 101 to rotate. At the same time, the end button assembly 3 drives the transmission assembly 20 to achieve synchronous rotation of the brush assembly.

[0107] Specifically, such as Figures 10 to 12 As shown, the terminal button assembly 3 includes a first gear 121 and an elastic member 3A; the first gear 121 is sleeved on one end of the elastic member 3A, and the clamping portion 321 on the outer edge of the terminal button body 32 of the elastic member 3A is clamped with the roller assembly 10 in the inner cavity of the roller assembly 10.

[0108] In some embodiments, as Figures 10 to 12 As shown, the elastic member 3A includes a terminal button mounting seat 1d that is sealed and sleeved on one end of the thermally conductive protective tube 1g, a terminal button body 32 that is sleeved on the end of the output shaft 1b, a telescopic cap 35 that is sleeved on the inner wall of the terminal button body 32, a spring 39 that provides elastic force for the telescopic cap 35, and an end cap 33 that is fixedly connected to the telescopic cap 35 by a screw 38; one end of the terminal button mounting seat 1d is sleeved on the outer periphery of the output shaft 1b and is detachably connected to the output end sealing plug 1c, and the outer edge of the other end is clamped on the end opening of the thermally conductive protective tube 1g of the motor; the middle part of the terminal button body 32 is through-set and includes a sleeve end (not marked in the drawings). ) and an accommodating end (not marked in the drawings), the sleeve end is sleeved and installed on the rotating end of the output shaft 1b, the accommodating end has a spring sleeve end (not marked in the drawings), and the outer periphery of the spring sleeve end has a clamping portion 321 for driving the cleaning roller to rotate; one end of the telescopic cap 35 is sleeved on the spring sleeve end and is limited by the limiting structure between the spring sleeve end and the end cap 33; the spring 39 is clamped between the end cap 33 and the terminal button mounting seat 1d so that the end cap 33 extends out of the spring sleeve end; one end of the end cap 33 is sleeved on the end of the telescopic cap 35, and the other end is sleeved on the inner ring of the first gear 121. It should be noted that the cylindrical shape of the outer edge of the end cap 33 away from the telescopic cap 35 is merely intended to facilitate the fit between the outer edge of the end cap 33 and the inner ring of the first gear 121. Accordingly, the outer edge of the end cap 33 away from the telescopic cap 35 can be configured as a polygonal column, and the inner ring of the first gear 121 can also be configured as a polygonal column, as long as a transitional fit is achieved between the two and they can drive each other to rotate synchronously. This application does not impose any specific limitations on the shape of the outer edge of the end cap 33 or the shape of the inner ring of the first gear 121.

[0109] In some embodiments, as Figure 11 、 Figure 15As shown, the end cap 33 is provided with a driving tooth 331 on the outer edge wall of one end side that abuts against the first gear 121, and a first copper sleeve 1225 is provided between the first gear 121 and the driving tooth 331. The first copper sleeve 1225 is fixed on the inner layer 4031 of the second side wall during the injection molding process of the cleaning head shell 401. In order to prevent the transition fit between the cylindrical outer edge of the end cap 33 away from the end button body 32 and the cylindrical inner ring of the first gear 121 from slipping against each other when the resistance is too large, resulting in the inability to transmit power to the brush assembly, the driving tooth 331 is a gear ring extending around the outer edge of the end cap 33 close to the end button body 32 in the direction away from the end button body 32, and the corresponding first gear 121 is provided with a tooth groove on the side that cooperates with the driving tooth 331. The gear ring of the driving tooth 331 engages with the tooth groove of the first gear 121, so that even when the inner ring of the first gear 121 and the outer edge of the end cap 33 away from the end button body 32 slip, power transmission can still be achieved by the mutual engagement of the gear ring tooth grooves. The first copper sleeve 1225 is fixed on the inner layer 4031 of the second side wall during the injection molding process of the cleaning head shell 401, which can ensure a higher coaxiality of the first copper sleeve 1225 and the corresponding coupling holes of the cleaning head shell 401, and can reduce the wear between the outer edge of the end cap 33 away from the terminal button body 32 and the first copper sleeve 1225.

[0110] In some embodiments, as Figures 10 to 12 As shown, the limiting structure includes a limiting waist-shaped hole 36 and a limiting pin 37. The limiting waist-shaped hole 36 is opened on the side wall of the end cap 33 along the telescopic direction of the end cap 33, and the limiting pin 37 is passed through the side wall of the spring sleeve end to limit the limiting waist-shaped hole 36.

[0111] The cleaning roller 100 provided by the present invention has an end button assembly 3 that is coupled to drive one end of the inner wall of the inner cylinder 101 of the roller assembly 10 under the drive of the motor 1A, thereby synchronously driving the roller assembly 10 to rotate. The end button assembly 3 has an axial movable stroke along the motor 1A, so that when the cleaning roller assembly 100 needs to repair and disassemble the motor 1A of the motor drive assembly 1, it is only necessary to press the end button assembly 3 to pull the roller assembly 10 out from the motor assembly 1, and then further disassemble and install the motor 1A. It is more convenient to repair and disassemble the drive motor sleeved in the cleaning roller assembly 100.

[0112] In some embodiments, as Figures 10 to 12As shown, a second bearing N is sleeved around the outer periphery of the sleeve end of the end button body 32. The inner ring of the second bearing N transitionally fits with the outer periphery of the sleeve end of the end button body 32, and the outer ring of the bearing N transitionally fits with the end button mounting seat 1d. In this way, the end button mounting seat 1d of the motor assembly 1 does not rotate, but the output shaft 1b of the motor assembly 1 rotates to drive the end button body 32. The second bearing N achieves a rotational connection between the end button body 32 and the end button mounting seat 1d, providing stable rotational support for the end button assembly 3 under the drive of the output shaft 1b of the motor assembly 1. The end button assembly 3 is also coupled to the transmission mechanism 20 and the roller assembly 10 for rotation. The second bearing N further enhances the rotational stability of the brush assembly and the cleaning roller 100.

[0113] The cleaning roller assembly 100 provided by the present invention has a terminal button body 32 of its terminal button assembly 3 driven to rotate by the output shaft 1b of the motor assembly 1, and the clamping portion 321 of the terminal button body 32 is clamped with one end of the roller assembly 10 of the floor scrubber to drive the roller assembly 10 to rotate; its terminal button assembly 3 has an axial movable stroke along the motor 1A. When it is necessary to disassemble and maintain the motor assembly 1 sleeved in the cleaning roller assembly 100, it is only necessary to press the end cap 33 of the terminal button assembly 3, and the end cap 33 pushes the telescopic cap 35 of the terminal button assembly 3 to contract, so that the clamping end of the cleaning roller assembly 100 can be rotated out from the clamping position of the cleaning head shell 401, and then it is more convenient to pull out the roller assembly 10.

[0114] Example 3:

[0115] This series of embodiments differs from the aforementioned embodiments mainly in the specific structure of the drum assembly 10. The parts that are the same as the technical solutions of the aforementioned embodiments will not be repeated here.

[0116] In some embodiments, as Figures 13 and 14 As shown, the roller assembly 10 also includes an inner sleeve 103 that can be inserted into the inner cylinder 101 from one end and a coupling 104 that is detachably connected to the inner surface of one end of the inner sleeve. The clamping portion 321 of the terminal button body 32 (or the output shaft 1b drives the coupling fixedly connected thereto) is coupled to the coupling 104 to drive the inner sleeve 103 to rotate. The rotation of the inner sleeve 103 drives the inner cylinder 101 to rotate, thereby synchronously driving the roller assembly 10 to rotate.

[0117] Specifically, the inner sleeve 103 can be made of metal to further enhance the ability to dissipate heat outward from the motor 1A of the motor assembly 1. The coupling 104 and the inner sleeve 103 are detachably fixedly connected, which reduces the difficulty of forming the coupling 104 area of the integral inner sleeve 103. Because the coupling 104 and the inner sleeve 103 do not need to be replaced each time the consumables of the roller assembly 10 are replaced, the cost of replacing consumables is further reduced.

[0118] Furthermore, the outer edge of the inner sleeve 103 and the inner wall of the inner cylinder 101 can be formed into a tooth-shaped structure that engages with each other. This tooth-shaped structure can increase the surface area of the inner sleeve 103 that can dissipate heat externally, while also increasing the surface area of contact with the inner wall of the inner cylinder 101, thereby increasing the friction between the two and facilitating the smooth rotation of the entire drum assembly 10. The tooth profile can be T-shaped, V-shaped, A-shaped, M-shaped, W-shaped, N-shaped, P-shaped, etc., as long as the outer edge of the inner sleeve 103 and the inner wall of the inner cylinder 101 can be separated by lateral pulling. This application does not impose any specific restrictions on the specific form of the tooth-shaped structure.

[0119] Of course, the outer edge of the inner sleeve 103 and the inner wall of the inner tube 101 can also be matched in the form of a cylindrical surface with a certain friction force, a multi-prism surface, or a special-shaped prism surface. As long as the outer edge of the inner sleeve 103 and the inner wall of the inner tube 101 can be separated by lateral pulling, this application does not make any specific restrictions on the specific form of the matching structure between the two.

[0120] The outer cylinder 102 is constantly squeezed by a water squeeze bar (not shown in the drawing) mounted on the cleaning head housing 401 of the floor scrubber based on the principle of water and dust circulation. Simultaneously, the outer cylinder 102 is also squeezed by solid waste on the surface to be cleaned during cleaning. After the entire drum assembly 10 has been used for a period of time, the outer cylinder 102 will experience a certain degree of wear. When the wear reaches a certain degree, the cleaning efficiency of the entire floor scrubber will be seriously affected.

[0121] The cleaning roller assembly 100 provided by the present invention, when the roller assembly 10 needs to be replaced and maintained, only the inner sleeve 103 needs to be pulled out, which automatically brings out the coupling part 104. It is only necessary to replace the new assembly consisting of the inner cylinder 101 and the outer surface of 101 covered with a new outer cylinder 102, and the roller assembly 10 can be quickly maintained, which not only improves the efficiency of maintaining the roller assembly 10, but also reduces the cost of consumables for replacing the roller assembly 10.

[0122] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the method and core ideas of the present application. At the same time, changes or modifications made by those skilled in the art based on the ideas of the present application, the specific implementation methods, and the scope of application of the present application, all fall within the scope of protection of the present application. In summary, the contents of this specification should not be construed as limiting the present application.
