Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning head shell and a cleaning head mechanism. Background Art

[0002] In recent years, floor scrubbers on the market often include a cleaning head and a handle. The cleaning head is provided with a roller assembly for scrubbing the floor, and a brush assembly for scraping the roller. The floor scrubber cleans the floor by driving the roller assembly to rotate, and scrapes the surface of the roller assembly with the brush, sweeping the garbage on the surface of the roller into the floor scrubber, thereby achieving the floor scrubbing function.

[0003] On the one hand, in the current floor scrubber products, the brush assembly has two forms: driven by a motor alone and driven synchronously by a drum motor. It is troublesome to disassemble the brush part for maintenance. When disassembling the brush part of the brush assembly driven by a motor alone or driven synchronously by a drum motor, it is difficult to separate the brush from the floor scrubber housing and the drive motor or drum motor synchronization mechanism. In addition, when the brush assembly is not installed in place, it often causes the bristles to fail to brush the drum, resulting in low solid waste cleaning efficiency of the floor scrubber; or, the interference of the brush against the drum is too large, resulting in excessive noise from the bristles hitting the drum when the floor scrubber is working.

[0004] On the other hand, in the current floor scrubber products, the floor scrubber mop is provided with a roller assembly for scrubbing the floor, a water squeezing device for squeezing the outer surface of the roller assembly, and a water flow pipeline for conveying clean water to the outer surface of the roller assembly and collecting sewage into the sewage tank. In the halfway after the water flow pipeline passes through the outer surface of the roller assembly, the sewage collection pipeline is a narrow side wall channel at one end of the side of the floor scrubber mop shell connecting the outer surface of the roller assembly to the sewage inlet of the sewage tank. When a large amount of cleaning liquid is sprayed on the floor or a large amount of cleaning liquid is added to the clean water tank, after the outer surface of the roller assembly is squeezed by the water squeezing device, a large amount of foam mixed with bubbles is often generated at the sewage collection end in the water flow channel. The foam mixed with bubbles hinders the flow efficiency of the sewage, and is also easy to flow along the gap of the side wall of the floor scrubber mop to the cleaned floor, resulting in low floor cleaning efficiency and easy wetness.

[0032] In a second aspect, the utility model further provides a cleaning head mechanism, comprising the cleaning head housing as described in the first aspect, and a cleaning roller, a transmission assembly and a brush assembly installed in the cleaning head housing and drivingly matched in sequence.

[0033] The beneficial effects of the above technical solution provided by the embodiment of the utility model at least include:

[0034] The cleaning head shell provided by the embodiment of the utility model can, on the one hand, reduce the difficulty of disassembling and maintaining the brush assembly from the cleaning head, and through the transmission effect of the transmission assembly arranged on the side wall of the cleaning head shell, directly transmit the power of driving the roller assembly to rotate to the brush assembly, so as to realize the synchronous operation of the roller assembly and the brush assembly. Compared with the scheme of driving the roller assembly and the brush assembly to work respectively through two driving devices, the cleaning head shell provided by the embodiment of the utility model does not need to be electrically connected to the motor that drives the brush assembly separately, which simplifies the installation process of the cleaning head mechanism. The brush assembly is provided with an installation positioning member that can be snapped into the cleaning head mechanism and is equipped with a magnetic sheet. The brush assembly installation part on the side wall of the cleaning head shell provided by the embodiment of the utility model is provided with a magnetic sheet. Through the mutual attraction between the magnetic sheet and the magnetic sheet, the brush assembly can be easily installed or removed, so that the brush assembly is easy to maintain and replace. At the same time, the rotation connection between the rotating shaft of the brush body and the installation positioning member is realized by magnetic attraction, which improves the convenience and accuracy of the connection alignment between the brush body and the installation positioning member. A detachable magnetic sheet is provided on an outer side wall of the brush assembly mounting portion of the cleaning head housing, and the brush assembly can be firmly fixed at the brush assembly mounting portion through the magnetic attraction between the mounting positioning piece and the brush assembly mounting portion of the cleaning head housing, thereby improving the stability of the brush assembly during use when installed in the cleaning head housing, avoiding radial vibration of the brush assembly, and further reducing the noise of the whole machine when the floor scrubber is working. Similarly, when the user installs one end of the mounting positioning piece of the brush assembly to the brush assembly mounting portion of the cleaning head housing, the mounting positioning piece will be automatically attracted to the groove of the brush assembly mounting portion under the action of the magnetic attraction between the magnetic member and the magnetic sheet, thereby improving the convenience of the user to install the brush assembly.

[0035] On the other hand, the sewage reflux pressure relief mechanism of the cleaning head shell is used to guide the sewage squeezed out from the cleaning roller of the floor scrubber to flow back to the water tank, so as to prevent the air pressure discharged to the outside when the sewage is guided to the sewage chamber of the water tank and the cleaning liquid mixed with bubbles and foam from leaking through the side wall. When the sewage flows into the sewage chamber of the water tank along the sewage guiding channel, even if the sewage guiding channel does not have enough space to defoam the residual cleaning liquid mixed with bubbles and foam in the sewage, the cleaning liquid mixed with bubbles and foam can flow into the sewage chamber along the sewage guiding channel. Since the exhaust channel opened by the abutment interface set on the back of the second convex weir can continuously discharge the air pressure that needs to be discharged from the sewage chamber after the sewage enters, the cleaning liquid with bubbles and foam in the sewage chamber can continue to defoam by itself until the pressure inside and outside the sewage chamber is balanced, and all the bubbles will naturally dissipate. On the other hand, a simple side cover assembly of the sewage return pressure relief mechanism of the cleaning head shell is used to seal the side wall of the floor scrubber mop head. The two functions of draining sewage and releasing pressure to the outside of the sewage channel and the exhaust channel are realized through one part, which improves the convenience of users to regularly maintain the sewage channel and the exhaust channel.

[0069] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0070] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "far", "near", "front", "rear" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0071] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0072] The applicant's patent with application number CN202220506875.9 discloses a brush roller and a floor scrubber equipped with a brush roller. The applicant's patent with application number CN202220270430.5 discloses a cleaning roller brush and a cleaning tool. The above-mentioned brush roller, floor scrubber equipped with a brush roller, cleaning roller brush and cleaning tool are all driven by a separate drive motor to drive the gear set to rotate, thereby driving the brush assembly to rotate. The roller assembly is driven by another separate drive motor, so that the brush assembly and the roller assembly rotate in opposite directions, thereby realizing synchronous operation of the roller assembly and the brush assembly. However, the dual motors driving the brush assembly and the roller assembly separately will consume more electricity, reducing the power endurance time of the floor scrubber.

[0073] After further improvement and testing, the inventor found that, on the one hand, it is difficult to separate the brush from the housing of the scrubber and the synchronous mechanism with the drum motor when the brush assembly is partially disassembled, which is driven by a motor alone or synchronously driven by a drum motor. In addition, when the brush assembly is not installed properly, the bristles often fail to brush the drum, resulting in low solid waste cleaning efficiency of the scrubber; or, the interference between the brush and the drum is too large, resulting in excessive noise from the bristles hitting the drum when the scrubber is working. On the other hand, as in the technical solutions disclosed in the patents with application numbers CN202123103793.4 and CN202111512775.3, the water tank on the side of the floor scrubber mop collects the sewage to the transfer filter bin, which can indeed filter the garbage in the sewage while defoaming the residual cleaning liquid in the sewage through the filter holes, and avoid the problem that the bubbles mixed in the sewage hinder the flow efficiency of the sewage. However, in the case that the entire space of the floor scrubber mop is very limited, freeing up a part of the space to arrange the transfer filter bin will cause the volume of the entire floor scrubber mop to increase invisibly. In the case that the entire space of the floor scrubber mop is very limited, adding an additional transfer filter bin will occupy the space in the water tank to hold clean water or sewage.

[0074] Based on this, the utility model provides a cleaning head housing, which is described below through specific embodiments.

[0075] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, the utility model provides a cleaning head housing 2, which is used to install a cleaning roller 4, a water tank 1 and a brush assembly 3 of a floor scrubber. The cleaning head housing includes a cleaning head housing body 20 and a detachable upper cover 5. The cleaning head housing body 20 has a left side wall 20a and a right side wall 20b. The right side wall 20b is used to fix a driving motor (not shown in the drawings) for driving the cleaning roller 4 to rotate and to clamp the brush assembly 3 with a magnetic suction member 33a. The left side wall 20a is provided with a magnetic suction member 33a for transmitting power from the cleaning roller to the brush assembly 3. The transmission assembly 6 of the brush assembly, the cleaning roller 4 and the brush assembly 3 are clamped between the left side wall 20a and the right side wall 20b, and the water tank 1 can be horizontally inserted into or pulled out of the middle and rear end of the cleaning head shell body 20; the detachable upper cover 5 is arranged at the opening at the front end of the cleaning head shell body 20 to clamp the cleaning roller and the brush assembly; wherein, the magnetic sheet 23 that is magnetically matched with the right side wall and one end of the brush assembly makes the brush assembly 3 smoother and easier to install to the right side wall 20b.

[0076] Further, see Figures 5 to 8 As shown, the brush assembly 3 includes a brush body 30, a rotating shaft 31 integrally formed with the brush body 30, and a mounting positioning member 33 rotatably matched with the rotating shaft 31. The brush body 30 includes a brush rod 302 integrally formed with the rotating shaft 31, and multiple rows of spaced bristles 301 are implanted axially around the brush rod 302. The bristles 301 include first bristles (not shown in the figure) and second bristles (not shown in the figure) spaced from each other. The roots of the first bristles and the second bristles are implanted inward from the outer surface of the brush rod 302. The free ends of the first bristles and the second bristles can elastically abut against the sponge layer on the outer surface of the cleaning roller 4. The length of the exposed portion of the first bristles is shorter than that of the exposed portion of the second bristles. The hardness of the bristles is stronger than that of the second bristles. The free end of the first bristles uses a smaller interference to be more "hard" to "brush and squeeze" the solid garbage absorbed by the sponge layer on the outer surface of the cleaning roller 4, and the free end of the second bristles uses a larger interference to be more "soft" to "brush and wipe" the solid garbage absorbed by the sponge layer on the outer surface of the cleaning roller 4. The first bristles and the second bristles alternately use different interferences and different elastic contact forces to intermittently brush the solid garbage absorbed by the sponge layer on the outer surface of the cleaning roller 4, which can improve the cleaning ability of the floor scrubber to clean solid garbage.

[0077] Further, such as Figures 5 to 8 As shown, the brush body 30 further includes a first end 30a coupled to the third gear member 63 of the transmission assembly 6, and a second end 30b coupled to the mounting positioning member 33; the brush body 30 is detachably connected to the mounting positioning member 33 via a rotating shaft 31, and can rotate relative to the mounting positioning member 33;

[0078] Further, such as Figures 5 to 8As shown, the cleaning head shell body 20 includes a brush assembly mounting portion (not marked in the figure) arranged on the right side wall 20b and a transmission assembly 6 arranged on the left side wall 20a. A cleaning roller 4 is clamped between the two side walls of the cleaning head shell body 20. The mounting positioning member 33 is clamped on the brush mounting portion. The transmission assembly 6 is respectively connected to the brush body 30 and the cleaning roller 4 in transmission connection; the cleaning roller 4 can rotate under the action of an external driving force, so as to drive the brush body 30 to rotate in the same direction relative to the cleaning roller 4 through the transmission action of the transmission assembly 6. It should be noted that the same-direction rotation mentioned here means that the rotation direction of the brush body 30 is consistent with the rotation direction of the cleaning roller 4, such as Figure 4 As shown, the cleaning roller 4 rotates clockwise when viewed from the left end face, and the brush body 30 also rotates clockwise when viewed from the left end face. From the moment when the end of the bristles 301 of the brush body 30 contacts the sponge layer on the outer surface of the cleaning roller 4, the linear velocity of the contact point of the end of the bristles 301 of the brush body 30 moving along the tangential direction and the linear velocity of the contact point of the sponge layer on the outer surface of the cleaning roller 4 moving along the tangential direction are opposite to each other. That is to say, the relative velocity of the contact point of the end of the bristles 301 of the brush body 30 and the sponge layer on the outer surface of the cleaning roller 4 is the sum of the two linear velocities, which is more conducive to brushing solid waste off the sponge layer on the outer surface of the cleaning roller 4 at high speed.

[0079] In this embodiment, when the cleaning roller 4 rotates under the action of an external driving force, the rotation of the cleaning roller 4 is transmitted to the brush body 30 due to the transmission action of the transmission assembly 6. The brush body 30 rotates in the same direction relative to the cleaning roller 4, thereby realizing the synchronous operation of the cleaning roller 4 and the brush assembly 3. That is, while the cleaning roller 4 cleans the ground, the brush assembly 3 sweeps and brushes the surface of the cleaning roller 4, thereby improving the efficiency of ground cleaning.

[0080] In a specific embodiment, referring to Figure 5 As shown, the transmission assembly 6 may include a first gear member 61, a second gear member 62 and a third gear member 63; the second gear member 62 is located between the first gear member 61 and the third gear member 63, and is respectively meshed with the first gear member 61 and the third gear member 63, fixing the first gear member 61 to the cleaning roller 4, and when the cleaning roller 4 rotates under the action of an external driving force, the first gear member 61 rotates with the cleaning roller 4, so that the second gear member 62 and the third gear member 63 also start to rotate due to the meshing action, and the third gear member 63 has the same rotation direction as the first gear member 61; the third gear member 63 is coupled and linked to the brush body 30, so that the brush body 30 rotates in the same direction relative to the cleaning roller 4 under the transmission action of the transmission assembly 6.

[0081] In a specific embodiment, referring to Figure 5 , Figure 6As shown, the first end 30a of the brush body 30 close to the transmission assembly 6 is provided with a driven coupling part (not shown in the figure), which is a polygonal protrusion of the brush rod 302 extending outward from the first end 30a toward the direction of the third gear member 63, and the third gear member 63 is centrally provided with a blind hole (not shown in the figure) corresponding to the driven coupling part, which can extend into the blind hole and cannot rotate in the blind hole; when the third gear member 63 rotates, the brush body 30 rotates under the drive of the third gear member 63. In this embodiment, the driven coupling part can be a polygonal column, such as a quadrangular column or a hexagonal column, and correspondingly, the blind hole can be a hole with an inner quadrangle or an inner hexagon.

[0082] In a specific embodiment, referring to Figures 5 to 9 As shown, the brush body 30 includes a brush rod 302 and at least two groups of bristles 301 arranged along the circumferential direction of the brush rod, each group of bristles 301 is arranged along the length direction of the brush rod 312, and the bristles 301 at least partially contact the outer surface of the cleaning roller 4, so as to sweep and brush the outer surface of the cleaning roller 4 by rotating in the same direction relative to the cleaning roller 4. The number of groups of brushes can be reasonably set according to the size of the outer diameter of the cleaning roller 4 and the outer diameter of the brush rod 302. For example, if the outer diameter of the brush rod 302 is large, the outer diameter of the cleaning roller 4 is also large. In order to achieve full-angle sweeping of the surface of the cleaning roller 4, three or more groups of bristles 301 can be set.

[0083] In this embodiment, the brush body 30 of the brush assembly 3 can rotate relative to the mounting positioning member 33, so that the power for driving the cleaning roller 4 to rotate is directly transmitted to the brush assembly 3 through the transmission action of the transmission assembly 6, thereby realizing the synchronous operation of the cleaning roller 4 and the brush assembly 3. While the cleaning roller 4 cleans the ground, the outer surface of the cleaning roller 4 is swept and brushed by the brush body 30. The brush body 30 does not need a separate driving motor to drive it, which saves driving energy, improves the battery life, and reduces noise.

[0084] In a specific embodiment, referring to Figure 6As shown, the right side wall 20b of the cleaning head housing body 20 is provided with a brush assembly mounting portion for detachably mounting the mounting positioning member 33. The left side wall 20a of the cleaning head housing body 20 is provided with a transmission assembly 6, and the third gear member 63 of the transmission assembly 6 realizes coupling with the brush assembly 3 through the driven coupling portion, so that the brush body 30 rotates in the same direction relative to the cleaning roller 4 under the transmission action of the transmission assembly 6. When installing the brush assembly 3 to the cleaning head housing body 20, first extend the driven coupling portion of the brush assembly 3 into the blind hole of the third gear member 63, and then slide one end of the mounting positioning member 33 of the assembly consisting of the assembled brush body 30, the rotating shaft 31, and the mounting positioning member 33 along the two guide side walls (not shown in the drawings) of the mounting positioning member 33 and install it to the brush assembly mounting portion. When removing the brush assembly 3 from the cleaning head shell 2, first remove the installation positioning member 33 of the brush assembly 3 upward from the brush assembly installation portion, and then separate the driven coupling portion from the blind hole of the third gear member 63 along the axial direction of the brush rod 302 away from the blind hole direction of the third gear member 63, thereby completing the removal of the brush assembly 3 from the cleaning head shell 2.

[0085] In a specific embodiment, referring to Figures 7 to 9 As shown, the second end portion 30b of the brush body 30 is integrally formed with a rotating shaft 31, and the mounting positioning member 33 is provided with an axial hole (not marked in the drawings) that penetrates the thickness of its end wall, and the rotating shaft 31 is passed through the axial hole of the mounting positioning member 33, so that the brush body 30 can rotate relative to the mounting positioning member 33 through the rotating shaft 31; during assembly, the driven coupling portion of the brush body 30 is engaged with the blind hole of the third gear member 63, and after the rotating shaft 31 is passed through the axial hole in the mounting positioning member 33, the mounting positioning member 33 is inserted into the brush assembly mounting portion, so that the brush assembly 3 is movably arranged in the cleaning head shell 2, and the brush assembly 3 can be disassembled from the cleaning head mechanism by pulling out the mounting positioning member 33, which greatly facilitates the maintenance and replacement of the brush assembly 3.

[0086] In this embodiment, refer to Figures 7 to 9As shown, the rotating shaft 31 is provided with a first knurled cylindrical surface 311, a first groove 312, a second knurled cylindrical surface 313, a second groove 314, a limiting boss 315, and a docking portion 316 in sequence from the inside to the outside on the cylindrical surface of the rotating shaft 31 starting from the inner end surface integrally formed with the second end portion 30b of the brush body 30. Among them, the first knurled cylindrical surface 311, the first groove 312, the second knurled cylindrical surface 313, and the second groove 314 of the rotating shaft 31 are all integrally formed in the second end portion 30b of the brush body 30, and the left end surface of the limiting boss 315 is just flush with the end surface of the brush rod 302. The first knurled cylindrical surface 311 and the second knurled cylindrical surface 313 of the rotating shaft 31 are arranged at intervals to increase the integral brush body 30 formed by the integrally formed brush rod 302 and the rotating shaft 31, when either of the two is subjected to an external twisting force, still ensure that the entire brush body 30 has good torsion resistance, so that the brush rod 302 and the rotating shaft 31 form a stable whole stably, and no mutual rotation occurs between the two. The first groove 312 and the second groove 314 of the rotating shaft 31 are arranged at intervals to increase the integral brush body 30 formed by the integrally formed brush rod 302 and the rotating shaft 31, when either of the two is subjected to an external tensile force along the axial direction of the brush rod 302, still ensure that the entire brush body 30 has good tensile resistance, so that the brush rod 302 and the rotating shaft 31 form a stable whole stably, and no mutual movement occurs between the two.

[0087] Further, see Figure 8 , Fig. 9As shown, the outer edge of one end of the limiting boss 315 facing the axial hole of the mounting positioning member 33 is provided with a chamfer, and the outer edge of the end of the axial hole of the mounting positioning member 33 facing the limiting boss 315 is provided with a chamfer, and the outer diameter of the limiting boss 315 is larger than the inner diameter of the axial hole of the mounting positioning member 33. After the brush body 30 integrally formed with the rotating shaft 31 is installed and matched with the mounting positioning member 33 at the axial hole of the mounting positioning member 33, a gap (not marked in the drawings) is left between the limiting boss 315 and the chamfer of the axial hole, and a larger gap is left between the docking portion 316 of the rotating shaft 31 and the axial hole of the mounting positioning member 33. The outer diameter of the brush rod 302 is much larger than the outer diameter of the limiting boss 315. In this way, after the brush assembly 3 has been used in the floor scrubber for a period of time, fine hairs are more likely to slowly accumulate at the limiting boss 315. When the fine hairs accumulate to a certain extent at the limiting boss 315, the fine hairs can continue to accumulate in the accommodation space through the gap. When the fine hairs accumulate in the accommodation space, the relative rotation of the rotating shaft 31 relative to the shaft hole of the installation positioning member 33 will be seriously blocked. At this time, the user needs to remove the brush assembly 3 by himself for timely cleaning. There is a gap between the chamfer of the limiting boss 315 and the shaft hole, and a large accommodation space is left between the docking portion 316 of the rotating shaft 31 and the shaft hole of the installation positioning member 33. This can extend the time interval for the user to manually maintain the brush assembly 3, reduce the frequency of manual maintenance of the brush assembly by the user, and improve the user experience.

[0088] Further, see Figure 8 , Fig. 9 As shown, the cylindrical outer surface of the docking portion 316 of the rotating shaft 31 may also be provided with a circle of oil storage grooves (not marked in the drawings). The user may apply lubricating grease to the cylindrical outer surface of the docking portion 316 of the rotating shaft 31 after each cleaning and maintenance of the brush assembly 3. The groove may allow the lubricating grease to stay in the accommodating space for a longer time, thereby further improving the smoothness of the brush assembly 3 during operation.

[0089] In this embodiment, refer to Figures 5 to 9As shown, a detachable magnetic member 33a is provided on the side of the installation positioning member 33 away from the brush body 30, and the rotating shaft 31 is made of magnetic material. After the installation positioning member 33 provided with the detachable magnetic member 33a is quickly docked with the rotating shaft 31 integrally formed with the brush body 30, under the action of the magnetic attraction between the rotating shaft 31 and the magnetic member 33a, the installation positioning member 33 can achieve "floating" rotatable docking with the rotating shaft 31. When the user needs to remove the brush assembly 3 from the cleaning head shell 2, he only needs to remove the installation positioning member 33 installed at the brush assembly installation part of the side wall of the cleaning head shell 2, and then separate the blind hole of the driven coupling part and the third gear member 63. Through the action of the magnetic attraction between the rotating shaft 31 and the magnetic member 33a, the user can naturally and easily remove the entire brush assembly 3 from the cleaning head shell 2.

[0090] Further, see Figure 7 As shown, the installation positioning member 33 includes an installation positioning member body 331 and a snap-on ear 322 arranged at one end of the installation positioning member body. The end of the installation positioning member 33 that cooperates with the brush assembly mounting portion is provided with a snap-on ear 332, and a groove (not shown in the figure) is provided at the brush assembly mounting portion of a side wall of the cleaning head housing 2, and the snap-on ear 332 can be engaged with the groove; the installation positioning member 33 is inserted into the brush assembly mounting portion of the right side wall 20b of the cleaning head housing 2, so that the snap-on ear 332 is engaged with the groove, thereby snapping the installation positioning member 33 to the brush assembly mounting portion, and preventing the installation positioning member 33 from loosening or slipping off.

[0091] Furthermore, the mounting locator body 331 may be provided with a hollow portion (not shown in the figure), and the mounting locator body 331 may be provided with a reinforcing rib (not shown in the figure), which can further reduce the overall weight of the mounting locator body 331 and improve the overall rigidity, thereby improving the stability of the brush assembly 3 during use when installed in the cleaning head housing 2, avoiding the axial and radial vibration of the brush assembly 3, and further reducing the overall noise of the scrubber when it is working. Figure 7 As shown, the hollow portion can be set to a U-shape, and the U-shaped hollow portion can enable the mounting positioning member body 331 to undergo slight elastic deformation relative to the mounting positioning member 33 as a whole, making the mounting positioning member 33 smoother and easier to install to the brush assembly mounting portion of the right side wall 20b.

[0092] In one embodiment, referring to Figure 6 , Figure 8 , Fig. 9As shown, further, a detachable magnetic sheet 23 can be provided at the brush assembly mounting portion of the right side wall 20b. After the brush assembly 3 is installed in place, the magnetic attraction between the magnetic member 33a and the magnetic sheet 23 can firmly fix the brush assembly 3 at the brush assembly mounting portion, thereby improving the stability of the brush assembly 3 during use when installed in the cleaning head housing 2, avoiding radial vibration of the brush assembly 3, and further reducing the noise of the whole machine when the floor scrubber is working. Similarly, when the user installs one end of the installation positioning member 33 of the brush assembly 3 to the brush assembly mounting portion of the right side wall 20b, under the action of the magnetic attraction between the magnetic member 33a and the magnetic sheet 23, the installation positioning member 33 will be automatically sucked to the groove of the brush assembly mounting portion, thereby improving the convenience of the user to install the brush assembly.

[0093] In one embodiment, referring to Figures 6 to 9 As shown, the magnetic member 33a is in the shape of a disk, and the magnetic member 33a blocks the shaft hole of the mounting positioning member 33 on the side of the mounting positioning member body 331 opposite to the rotating shaft 31. At the same time, the side of the magnetic member 33a opposite to the rotating shaft 31, the shaft hole of the mounting positioning member 33, the limiting boss 315, and the cylindrical surface and end surface of the docking portion 316 jointly enclose an accommodation space. Since the magnetic member 33a further blocks the accommodation space, the lubricating grease applied to the cylindrical surface and end surface of the docking portion 316 after the user disassembles the maintenance brush assembly 3 is also easier to stay and is not easy to lose.

[0094] In one embodiment, the magnetic member 33a is in the shape of a round cap, and the magnetic member 33a blocks the axial hole of the mounting positioning member 33 on the side of the mounting positioning member body 331 opposite to the rotating shaft 31. At the same time, the side of the magnetic member 33a opposite to the rotating shaft 31, the axial hole of the mounting positioning member 33, the limiting boss 315, and the cylindrical surface and end surface of the docking portion 316 together enclose a storage space, and the round cap-shaped magnetic member 33a itself also encloses more storage space. Since the magnetic member 33a further blocks the storage space, the lubricating grease applied to the cylindrical surface and end surface of the docking portion 316 after the user disassembles the maintenance brush assembly 3 is also easier to stay and not easy to lose. The round cap-shaped magnetic member 33a can further reduce the weight of the magnetic member 33a itself, increase the total volume of the storage space, and also leave more space for the docking portion 316 of the rotating shaft 31, so that the lubricating grease can wrap and lubricate the docking portion 316 of the rotating shaft 31 more fully. The round cap-shaped magnetic attraction member 33a can be prepared by stamping and re-excitation, and the cost of mass production can be further reduced.

[0095] In one embodiment, the magnetic member 33a is annular, and there is a gap between the inner diameter of the annular magnetic member 33a and the outer diameter of the docking portion 316 of the shaft 31. This slight gap allows the lubricating grease to still only wrap around the cylindrical surface and end surface of the docking portion 316 of the shaft 31 under the action of its own surface tension. The magnetic member 33a is embedded in the inner wall of the shaft hole of the mounting positioning member 33 on the side opposite to the shaft 31 on the mounting positioning member body 331. At the same time, the side of the magnetic member 33a opposite to the shaft 31, the shaft hole of the mounting positioning member 33, the limiting boss 315, and the cylindrical surface and end surface of the docking portion 316 jointly enclose a storage space, and the annular magnetic member 33a itself also encloses a storage space. Since the magnetic member 33a further blocks the storage space, the lubricating grease applied to the cylindrical surface and end surface of the docking portion 316 after the user disassembles the maintenance brush assembly 3 is also easier to stay and not easy to lose. The annular magnetic member 33a can further reduce the weight of the magnetic member 33a itself, increase the total volume of the accommodation space, and reserve more space for the docking portion 316 of the shaft 31, so that the lubricating grease can more fully wrap and lubricate the docking portion 316 of the shaft 31. The annular magnetic member 33a can be prepared by stamping and re-excitation, and the cost of mass production can be further reduced.

[0096] In one embodiment, referring to Figure 2 , Figure 3 As shown, the cleaning head shell 2 is provided with a sewage reflux pressure relief mechanism, which includes a sewage guiding channel N and an exhaust channel M on the left side wall 20a of the drag head shell body 20, and the sewage guiding channel N and the exhaust channel M constitute a complete sewage guiding and exhaust channel (not marked in the drawings), and the sewage guiding channel N is used to guide the sewage squeezed out from the cleaning roller 4 of the floor scrubber into the sewage chamber of the water tank 1 (not marked in the drawings), and an exhaust port 207 is provided in the exhaust channel M in an area corresponding to the outer surface of the cleaning roller 4, and the exhaust channel M is used to timely discharge the air discharged when the sewage is introduced into the sewage chamber from the cleaning head shell 2 to the outer surface of the cleaning roller 4, and the cleaning head shell 2 also includes a side cover assembly 7 for blocking the sewage guiding and exhaust channel to prevent the air pressure discharged to the outside when the sewage is guided to the sewage chamber and the cleaning liquid mixed with bubbles and foam from leaking through the left side wall 20a.

[0097] Further, see Figure 2 , Figure 3As shown, the front upper part of the floor scrubber tractor housing body 20 is provided with a cleaning groove (not marked in the drawing) connecting the two side walls of the left side wall 20a and the right side wall 20b, one end face of the cleaning groove faces the outer surface of the cleaning roller 4, and a squeezing bar (not marked in the drawing) elastically abutting against the outer surface of the cleaning roller 4 is provided on the end face, and a filtering device (not marked in the drawing) which is an integral part of the entire cleaning groove is provided in other areas of the end face other than the squeezing bar, and the cleaning groove is connected to the two side walls of the floor scrubber tractor housing body 20, and a first sewage outlet 204a and a second sewage outlet 204b are provided in the area connected to the cleaning groove on the left side wall 20a, and these two sewage outlets are collectively referred to as sewage outlets 204. When the floor scrubber is working, the cleaning roller 4 rotates, and the clean water flushed on the outer surface of the cleaning roller 4 is converted into sewage after being squeezed by the squeezing bar, and then passes through the filtering device and flows into the sewage exhaust channel along the channel of the cleaning groove through the first sewage outlet 204a and the second sewage outlet 204b.

[0098] In this embodiment, if Figure 2 , Figure 4As shown, the water tank 1 is an integrated water tank, and the water tank 1 is connected to the cleaning roller 4 through a water supply pipe, which includes a clean water suction pipe 21 for sucking clean water from the clean water outlet 11 of the water tank 1 and a clean water supply pipe 22 for conveying clean water to the cleaning tank on the surface of the cleaning roller. The other end of the clean water suction pipe 21 is connected to a water suction port of a water pump (not shown in the figure), and the other end of the clean water supply pipe 22 is connected to the water outlet of the water pump. The end of the integrated water tank 1 that is connected to a side wall of the floor scrubber tractor housing 2 is provided with a clean water outlet 11 and a sewage inlet 12. A sewage channel N for recovering sewage from the surface of the cleaning roller is also provided on one side wall of the floor scrubber tractor housing 2. The sewage channel N is a section of the sewage channel that is specifically used to drain sewage and is a part of the sewage channel. The part of the sewage channel that is removed from the sewage channel N is all an exhaust channel M. Further, the exhaust channel M can surround the sewage channel N. One end of the sewage channel N is connected to the sewage outlet 204 of the cleaning tank, and the other end of the sewage channel N is connected to the sewage return port 205 connected to the sewage cavity of the integrated water tank 1. The sewage return port 205 is connected to the sewage inlet 12 of the integrated water tank 1. An exhaust port 207 is provided on the side wall in the exhaust channel M in an area corresponding to the outer surface of the cleaning roller 4. The front side walls of the mop housing 2 of the floor scrubber are also connected with an air dispersion channel (not shown in the figure) arranged in parallel with the cleaning tank. The cleaning tank and the air dispersion channel are actually an integrated side-lying "S"-shaped beam (not shown in the figure) connecting the two side walls. The opening of the cleaning tank faces the top away from the cleaning roller 4. The opening of the cleaning tank is covered with a detachable cleaning tank sealing cover (not shown in the figure) for sealing the cleaning tank. The opening of the air dispersion channel faces the upper surface of the cleaning roller 4. The sewage enters the sewage cavity along the sewage guide channel N, and the air discharged is discharged into the air dispersion channel through the exhaust port 207 along the exhaust channel M. The pores of the sponge layer on the upper surface of the cleaning roller 4 can just absorb the air discharged from the sewage cavity, so that the cleaning liquid with bubbles in the sewage cavity can continue to defoam itself until the pressure inside and outside the sewage cavity is balanced, and all the bubbles are naturally dissipated.

[0099] In this embodiment, Fig.10 , Fig.11 As shown, the cleaning head shell body 20 also includes an integrated crossbeam (not shown in the figure) arranged to connect the left side wall 20a and the right side wall 20b, and the crossbeam is provided with an N-shaped air dispersion channel opening downward toward the bottom surface of the cleaning roller, and the exhaust port 207 connects the exhaust channel M and the air dispersion channel.

[0100] In this embodiment, Figure 2 , Figure 4As shown, the left side wall 20a of the cleaning head shell body 20 is provided with a flange 201 forming a closed ring, and the closed ring on the left side wall 20a is also provided with a first convex weir 202 connected to the flange 201 and forming a closed inner ring therewith, and the closed inner ring surrounds the sewage exhaust channel. The flange height of the flange 201 extending outward from the shell is flush with the first convex weir 202, and the upper section of the flange 201 and the first convex weir 202 together form a closed inner ring, and the left side wall of the scrubber head shell 2, the straight wall ring, and the inner wall of the side cover assembly 7 together surround the entire sewage exhaust channel;

[0101] Furthermore, the left side wall 20a is provided with a second convex weir 203 in the closed inner ring, which can form a small closed ring. Figure 3 As shown, the second convex weir 203 and a portion of the first convex weir 202 can together enclose the sewage channel N. Of course, if Figure 4 As shown, within the closed inner ring on the left side wall 20a, the second convex weir 203 can also independently enclose the sewage channel N.

[0102] Furthermore, the first convex weir 202 is U-shaped, and the two ends of the upper part thereof are connected to the inner wall of the flange 201 .

[0103] The height of the second convex weir 203 is lower than the flange 201 and the first convex weir 202. The second convex weir 203 encloses a straight-wall inner ring smaller than the aforementioned straight-wall ring in the entire sewage exhaust channel. The left side wall 20a of the cleaning head shell body 20, the straight-wall inner ring, and the inner wall of the side cover assembly 7 together enclose the sewage channel N.

[0104] Specifically, refer to Figure 5 , Figure 8 As shown, the sewage return side cover 7 is sealed and covered on the left side wall 20a of the cleaning head shell body 20. When the water tank 1 is inserted into the cleaning head shell body 20 and installed in place, the back of the left end of the upper straight edge of the second convex weir 203 connecting the exhaust channel M and the sewage guiding channel N of the left side wall 20a of the cleaning head shell body 20 elastically abuts against the sewage valve core (not shown in the figure) of the sewage inlet 12 of the water tank 1. The abutment interface opens the sewage channel for sewage to flow from the sewage outlet 204 through the sewage guiding channel N and then through the sewage return outlet 205 into the sewage inlet 12 to enter the sewage cavity. At the same time, the abutment interface also opens another exhaust channel outside the left side wall 20a of the cleaning head shell body 20, which is connected to the exhaust outlet 206 from the sewage inlet 12 through the exhaust channel M and then through the exhaust port 207 to discharge the air in the sewage cavity after the sewage enters the sewage cavity.

[0105] Combination Figure 3As shown, another exhaust channel outside the left side wall 20a of the cleaning head shell body 20 can be a diffuse air channel arranged in parallel with the cleaning tank. After the sewage enters the sewage chamber along the sewage guiding channel N, the air discharged is discharged into the diffuse air channel along the exhaust channel M through the exhaust port 207, and the pores of the sponge layer on the upper surface of the cleaning roller 4 can just absorb the air discharged from the sewage chamber. In this way, when the sewage flows into the sewage chamber of the integrated water tank 1 along the sewage guiding channel N, even if the sewage guiding channel N does not have enough space to defoam the residual foam cleaning liquid mixed with bubbles in the sewage, the foam cleaning liquid mixed with bubbles can flow into the sewage chamber along the sewage guiding channel N, because the opened exhaust channel M can always discharge the air pressure that needs to be discharged from the sewage chamber after the sewage enters, and the foam cleaning liquid with bubbles in the sewage chamber can continue to defoam itself until the pressure inside and outside the sewage chamber is balanced, and all the bubbles will naturally dissipate.

[0106] In this embodiment, Figure 5 As shown, the cleaning head shell 2 also includes a left side wall side cover 8 on the left side wall 20a of the cleaning head shell body 20 for sealing the area except the sewage exhaust channel. The left side wall side cover 8 can further seal and shield the water pipe and transmission assembly 6 installed on the left side wall 20a, which can enhance the visual beauty and overall sense of the entire cleaning head shell 2, and also prevent the components installed on the left side wall 20a from being soaked by water.

[0107] In the second aspect, based on the same inventive concept, the utility model also provides a cleaning head mechanism, referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the cleaning head mechanism includes the cleaning head shell 2 described in the first aspect above, and a cleaning roller 4, a transmission assembly 6 and a brush assembly 3 installed in the cleaning head shell 2 and matched with each other in sequence; the brush assembly 3 is installed on the brush assembly mounting portion of the right side wall 20b, and the transmission assembly 6 is respectively connected to the brush body 30 of the brush assembly 3 and the cleaning roller 4 in transmission; the cleaning roller 4 can rotate under the action of an external driving force, so as to drive the brush body 30 to rotate in the same direction relative to the cleaning roller 4 through the transmission action of the transmission assembly 6.

[0108] In a specific embodiment, referring to Figure 5 As shown, the cleaning head mechanism also includes a trash box 9 arranged below the brush assembly 3. The brush body 30 rotates in the same direction as the cleaning roller 4 to sweep the surface of the cleaning roller 4, thereby sweeping the garbage adhered to the surface of the cleaning roller 4 into the trash box 9 below the brush assembly 3.

[0109] In a specific embodiment, referring to Figure 1 , Figure 6 As shown, the cleaning head mechanism may also include a water tank 1, which is connected to the cleaning roller 4 through a water pipe, and is used to provide clean water to the cleaning roller 4 and recover the sewage generated by the cleaning roller 4. The clean water provided by the water tank 1 can wet the wiping layer on the outer surface of the roller assembly, so that the wiping layer can clean the floor. The cleaning head mechanism wipes the garbage on the floor through the cleaning roller 4, and sweeps the garbage adhered to the outer surface of the cleaning roller 4 into the garbage box 9 through the brush assembly 3; recovers the sewage adsorbed by the wiping layer on the surface of the cleaning roller 4 through the integrated water tank 1, and provides clean water to the wiping layer on the outer surface of the cleaning roller 4; through the cooperation of the cleaning roller 4, the brush assembly 3, the garbage box 9 and the water tank 1, the efficiency of floor cleaning is improved, and the cleaning effect is improved.

The present disclosure is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from its scope.
