Description

[0001] This application is a divisional application of Chinese Patent Application No. 202323591122.6, with an application date of December 27, 2023, and an invention title of "A cleaning head housing and a cleaning head mechanism", the content of which is incorporated herein by reference. Technical Field

[0002] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning head housing and a cleaning head mechanism. Background Art

[0003] In recent years, floor washers on the market often include a cleaning head and a handle. The cleaning head is provided with a roller assembly for scrubbing the ground and a brush assembly for scraping the roller. The floor washer drives the roller assembly to rotate to clean the ground, and scrapes the surface of the roller assembly through the brush to sweep the garbage on the surface of the roller into the floor washer, thereby realizing the floor washing function.

[0004] On the one hand, in current floor washer products, there are two forms of brush assemblies: driven separately by a motor and driven synchronously by a roller motor. When it is necessary to disassemble and maintain the brush part, it is relatively troublesome. For the brush assembly driven separately by a motor or driven synchronously by a roller motor, it is difficult to separate the brush from the floor washer housing and the synchronous mechanism of the driving motor or the roller motor when disassembling the brush part. In addition, when the brush assembly is not installed in place, it often causes the bristles to fail to reach the roller, resulting in too low solid waste cleaning efficiency of the floor washer; or, it causes the interference fit between the brush and the roller to be too large, resulting in too much noise when the bristles beat the roller during the operation of the floor washer.

[0005] On the other hand, in current floor washer products, the floor washer head is provided with a roller assembly for scrubbing the ground, a water squeezing device for squeezing the outer surface of the roller assembly, and a water flow pipeline for delivering clean water to the outer surface of the roller assembly and collecting sewage into a sewage tank. In the second half of the water flow pipeline after passing through the outer surface of the roller assembly, the sewage collection pipeline is a long and narrow side wall channel attached to one side of the floor washer head housing between the outer surface of the roller assembly and the sewage inlet of the sewage tank. When a large amount of cleaning liquid is sprayed on the ground 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 generated by the extrusion of the cleaning liquid from the sponge layer on the outer surface of the roller assembly often occurs at the sewage collection end in the water flow channel. These foam mixed with bubbles hinder the sewage flow efficiency, and at the same time, it is easy to flow along the gap of the side wall of the floor washer head to the already cleaned ground, resulting in low floor cleaning efficiency and easy slipperiness. Summary of the Utility Model

[0035] In one or some optional embodiments, the cleaning head housing further comprises a side cover assembly having a sealing cover disposed on the left side wall for sealing the sewage-conducting exhaust passage.

[0036] 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.

[0037] The beneficial effects of the above technical solution provided by the embodiment of the utility model at least include:

[0038] 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.

[0039] On the other hand, the sewage reflux pressure relief mechanism of the cleaning head housing is used to guide the sewage extruded from the cleaning roller of the floor washer back to the water tank, so as to prevent the air pressure 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 abutting interface arranged on the back of the second convex weir can always release the air pressure that needs to be discharged in 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 all the bubbles naturally dissipate when the pressure inside and outside the sewage chamber is balanced. On the other hand, the side cover assembly of the sewage reflux pressure relief mechanism of the cleaning head housing seals the side wall of the floor washer head of the floor washer through a simple assembly, and realizes the two functions of guiding sewage and discharging pressure outward through two channels, namely the sewage guiding channel and the exhaust channel, which improves the convenience for users to maintain the sewage guiding and exhaust channels regularly by themselves.

[0073] 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 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 so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0074] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "far", "near", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0075] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0076] The patent with the application number CN202220506875.9 of the applicant discloses a brush roller and a floor washer equipped with the brush roller. The patent with the application number CN202220270430.5 of the applicant discloses a cleaning roller brush and a cleaning tool. The above-mentioned brush roller, the floor washer equipped with the brush roller, the cleaning roller brush and the cleaning tool are all driven by a separate driving motor to drive the gear set to rotate, thereby driving the brush assembly to rotate. The roller assembly is driven by another separate driving motor, so that the brush assembly and the roller assembly rotate in opposite directions, thereby realizing the synchronous operation of the roller assembly and the brush assembly. However, separately driving the brush assembly and the roller assembly by two motors will consume more power and reduce the power endurance time of the floor washer.

[0077] After continuous improvement and test verification by the inventor, it is found that, on the one hand, for the brush assembly driven by the motor alone and synchronously driven by the roller motor, it is difficult to separate the brush from the floor washer housing and the synchronous mechanism of the roller motor when disassembling the brush part. In addition, when the brush assembly is not installed in place, it often causes the bristles to fail to reach the roller, resulting in too low cleaning efficiency of solid garbage in the floor washer; or, it causes too large interference fit between the brush and the roller, resulting in too much noise when the bristles beat the roller during the operation of the floor washer. On the other hand, as the technical solutions disclosed in the patents with the application numbers CN202123103793.4 and CN202111512775.3 of the applicant, the water tank on the side of the floor washer head converges sewage to the transfer and filtration bin, which can indeed filter the garbage in the sewage and defoam the residual cleaning liquid in the sewage through the filter holes at the same time, and can avoid the problem that the foam mixed with bubbles in the sewage hinders the flow efficiency of the sewage. However, in the case where the entire space of the floor washer head is very limited, setting aside a part of the space to arrange the transfer and filtration bin will invisibly increase the volume of the entire floor washer head. In the case where the entire space of the floor washer head is very limited, additionally adding a transfer and filtration bin will occupy the space for holding clean water or sewage in the water tank.

[0078] Based on this, the present utility model provides a cleaning head housing, which will be described below through specific embodiments.

[0079] Such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7As shown in the figure, the present utility model provides a cleaning head housing 2 for installing a cleaning roller 4, a water tank 1 and a brush assembly 3 of a floor washer. 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 drive motor (not shown in the drawing) for driving the cleaning roller 4 to rotate and to clamp the brush assembly 3 having a magnetic member 33a. The left side wall 20a is provided with a transmission assembly 6 for transmitting power from the cleaning roller to the brush assembly. The cleaning roller 4 and the brush assembly 3 are both clamped between the left side wall 20a and the right side wall 20b. The water tank 1 can be horizontally inserted into or withdrawn from the middle and rear ends of the cleaning head housing body 20. The detachable upper cover 5 is covered on the front end of the cleaning head housing body 20 to clamp the open part of the cleaning roller and the brush assembly. Among them, a magnetic sheet 23 that magnetically cooperates with one end of the brush assembly is provided on the right side wall, making it smoother and more convenient to install the brush assembly 3 on the right side wall 20b.

[0080] Further, referring to Figures 5 to 8 As shown in the figure, the brush assembly 3 includes a brush body 30, a rotating shaft 31 integrally formed with the brush body 30, and a mounting and positioning member 33 rotatably engaged with the rotating shaft 31. The brush body 30 includes a brush rod 302 integrally formed with the rotating shaft 31. A plurality of rows of bristles 301 are implanted along the axial direction around the brush rod 302 at intervals. The bristles 301 include first bristles (not shown in the drawing) and second bristles (not shown in the drawing) arranged at intervals. 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 exposed length of the first bristles is shorter than that of the second bristles. The hardness of the first bristles is stronger than that of the second bristles. The free ends of the first bristles "brush and squeeze" the solid waste adsorbed on the sponge layer on the outer surface of the cleaning roller 4 with a smaller interference fit and are more "rigid". The free ends of the second bristles "brush and smear" the solid waste adsorbed on the sponge layer on the outer surface of the cleaning roller 4 with a larger interference fit and are more "soft". The first bristles and the second bristles alternately use different interference fits and different elastic abutting forces to intermittently brush the solid waste adsorbed on the sponge layer on the outer surface of the cleaning roller 4, which can improve the cleaning ability of the floor washer to clean solid waste.

[0081] Further, as Figures 5 to 8 shown in the figure, the brush body 30 further includes a first end 30a coupled to a third gear member 63 of the transmission assembly 6, and a second end 30b coupled to the mounting and positioning member 33. The brush body 30 is detachably connected to the mounting and positioning member 33 through the rotating shaft 31 and can rotate relative to the mounting and positioning member 33.

[0082] Further, 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.

[0083] 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.

[0084] 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.

[0085] In a specific embodiment, referring to Figure 5 , Figure 6As shown, a driven coupling part (not shown in the figure) is provided at the first end 30a of the brush body 30 close to the transmission component 6. The driven coupling part is a polygonal protrusion where the brush rod 302 extends outward in the direction of the third gear member 63 at the first end 30a. A blind hole (not shown in the figure) corresponding to the driven coupling part is provided at the center of the third gear member 63. The driven coupling part can extend into the blind hole and cannot rotate within the blind hole. When the third gear member 63 rotates, the brush body 30 rotates driven by the third gear member 63. In this embodiment, the driven coupling part can be a prism, such as a quadrangular prism or a hexagonal prism. Correspondingly, the blind hole can be a hole with an internal quadrangle or an internal hexagon.

[0086] In a specific embodiment, referring to Figures 5 to 9 As shown, the brush body 30 of the brush assembly 3 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 at least part of the bristles 301 contacts the outer surface of the cleaning roller 4 to brush the outer surface of the cleaning roller 4 by rotating in the same direction as the cleaning roller 4. The number of groups of bristles can be reasonably set according to 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 relatively large and the outer diameter of the cleaning roller 4 is also relatively large, in order to achieve full-angle brushing of the surface of the cleaning roller 4, three or more groups of bristles 301 can be provided.

[0087] In this embodiment, the brush body 30 of the brush assembly 3 can rotate relative to the mounting and positioning member 33. Thus, through the transmission of the transmission component 6, the power to drive the cleaning roller 4 to rotate is directly transmitted to the brush assembly 3, realizing the synchronous operation of the cleaning roller 4 and the brush assembly 3. While the cleaning roller 4 is cleaning the ground, the outer surface of the cleaning roller 4 is brushed by the brush body 30. The brush body 30 does not require a separate drive motor, saving drive energy, increasing the battery life, and at the same time, reducing noise.

[0088] In a specific embodiment, referring to Figure 6As shown, a brush assembly mounting portion is provided on the right side wall 20b of the cleaning head housing body 20 for detachably mounting and clamping the mounting positioning member 33. A transmission assembly 6 is provided on the left side wall 20a of the cleaning head housing body 20. The third gear member 63 of the transmission assembly 6 realizes the coupling to the brush assembly 3 through the driven coupling portion, so as to realize the co-rotation of the brush body 30 relative to the cleaning roller 4 under the driving action of the transmission assembly 6. When installing the brush assembly 3 onto the cleaning head housing body 20, first insert 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 composed of the brush body 30, the rotating shaft 31, and the mounting positioning member 33 along the two guiding side walls (not shown in the drawings) of the mounting positioning member 33 and install it into the brush assembly mounting portion. When removing the brush assembly 3 from the cleaning head housing 2, first take out the mounting positioning member 33 of the brush assembly 3 upward from the brush assembly mounting 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 of the third gear member 63, thus completing the removal of the brush assembly 3 from the cleaning head housing 2.

[0089] In a specific embodiment, referring to Figures 7 to 9 As shown, a rotating shaft 31 is integrally formed at the second end portion 30b of the brush body 30. A shaft hole (not shown in the drawings) penetrating the wall thickness of the end wall is provided in the mounting positioning member 33. The rotating shaft 31 is inserted into the shaft 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 fitted into the blind hole of the third gear member 63. After the rotating shaft 31 is inserted into the shaft hole in the mounting positioning member 33, the mounting positioning member 33 is then snapped into the brush assembly mounting portion, thereby movably arranging the brush assembly 3 in the cleaning head housing 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.

[0090] In this embodiment, referring to Figures 7 to 9As shown, starting from the inner end face integrally formed with the second end portion 30b of the brush body 30, the rotating shaft 31 is successively provided with a first rolling column surface 311, a first groove 312, a second rolling column surface 313, a second groove 314, a limiting boss 315, and a docking portion 316 on the column surface of the rotating shaft 31 from inside to outside. Among them, the first rolling column surface 311, the first groove 312, the second rolling column surface 313, and the second groove 314 of the rotating shaft 31 are all integrally formed inside the second end portion 30b of the brush body 30, and the left end face of the limiting boss 315 is exactly flush with the end face of the brush rod 302. The first rolling column surface 311 and the second rolling column surface 313 of the rotating shaft 31 are arranged at intervals, which can increase the torsional resistance of the overall brush body 30 formed by the brush rod 302 and the rotating shaft 31 after integral molding when either of them is subjected to an externally applied torsional force, ensuring that the entire brush body 30 has good torsional resistance and enabling the brush rod 302 and the rotating shaft 31 to firmly form a stable whole without relative rotation between them. The first groove 312 and the second groove 314 of the rotating shaft 31 are arranged at intervals, which can increase the tensile resistance of the overall brush body 30 formed by the brush rod 302 and the rotating shaft 31 after integral molding when either of them is subjected to an externally applied tensile force along the axial direction of the brush rod 302, ensuring that the entire brush body 30 has good tensile resistance and enabling the brush rod 302 and the rotating shaft 31 to firmly form a stable whole without relative movement between them.

[0091] Further, referring to Figure 8 、 Figure 9As shown, a chamfer is provided at the outer edge of one end of the limit boss 315 facing the shaft hole of the mounting and positioning member 33, and a chamfer is provided at the outer edge of one end of the shaft hole of the mounting and positioning member 33 facing the limit boss 315. The outer diameter of the limit boss 315 is larger than the inner diameter of the shaft hole of the mounting and positioning member 33. After the brush body 30 integrally formed with the rotating shaft 31 is properly installed and fitted with the shaft hole of the mounting and positioning member 33, a gap (not marked in the drawing) is left between the chamfer of the limit boss 315 and the shaft hole. A relatively large accommodating space is left between the docking portion 316 of the rotating shaft 31 and the shaft hole of the mounting and positioning member 33. The outer diameter of the brush rod 302 is much larger than the outer diameter of the limit boss 315. In this way, after the brush assembly 3 is used in the floor washer for a period of time, fine hairs are more likely to gradually accumulate towards the limit boss 315. When the fine hairs accumulate at the limit boss 315 to a certain extent, the fine hairs can continue to accumulate towards the accommodating space through the gap. When the accommodating space is full of fine hairs, the relative rotation of the rotating shaft 31 with respect to the shaft hole of the mounting and positioning member 33 will be severely jammed. At this time, the user needs to remove the brush assembly 3 by himself for timely cleaning. A gap is left between the chamfer of the limit boss 315 and the shaft hole, and a relatively large accommodating space is left between the docking portion 316 of the rotating shaft 31 and the shaft hole of the mounting and positioning member 33. This can extend the time interval for the user to manually maintain the brush assembly 3, reduce the frequency of the user's manual maintenance of the brush assembly, and improve the user experience.

[0092] Further, referring to Figure 8 、 Figure 9 As shown, a circle of oil storage grooves (not marked in the drawing) can also be provided on the cylindrical outer surface of the docking portion 316 of the rotating shaft 31. After the user cleans and maintains the brush assembly 3 each time, lubricating grease can be applied to the cylindrical outer surface of the docking portion 316 of the rotating shaft 31. The grooves can make the lubricating grease stay in the accommodating space for a longer time, and can further improve the smoothness of the brush assembly 3 during operation.

[0093] In this embodiment, referring 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.

[0094] 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.

[0095] 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.

[0096] In one embodiment, referring to Figure 6 , Figure 8 , Figure 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.

[0097] 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.

[0098] 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.

[0099] In one embodiment, the magnetic member 33a is annular. 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 rotating shaft 31. This minute gap allows the lubricating grease to still only wrap around the cylindrical surface and end face of the docking portion 316 of the rotating 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 and positioning member 33 on the side opposite to the rotating shaft 31 on the mounting and positioning member body 331. At the same time, the side of the magnetic member 33a opposite to the rotating shaft 31, the shaft hole of the mounting and positioning member 33, the limiting boss 315, and the cylindrical surface and end face of the docking portion 316 together enclose an accommodation space, and the annular magnetic member 33a itself further encloses an accommodation space. Since the magnetic member 33a further seals the accommodation space, the lubricating grease applied to the cylindrical surface and end face of the docking portion 316 by the user after disassembling and maintaining the brush assembly 3 is also more likely to stay and not flow away. 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 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 annular magnetic member 33a can be prepared by stamping and then magnetization, and the cost of mass production can be further reduced.

[0100] In one embodiment, referring to Figure 2 , Figure 3 As shown, the cleaning head housing 2 is provided with a sewage return and pressure relief mechanism. The sewage return and pressure relief mechanism includes a sewage guiding channel N and an exhaust channel M on the left side wall 20a of the mop head housing body 20. The sewage guiding channel N and the exhaust channel M form a complete sewage guiding and exhaust channel (not marked in the drawing). The sewage guiding channel N is used to guide the sewage extruded from the cleaning roller 4 of the floor washer into the sewage chamber of the water tank 1 (not marked in the drawing). An exhaust port 207 is provided in the area of the exhaust channel M corresponding to the outer surface of the cleaning roller 4. 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 housing 2 to the outer surface of the cleaning roller 4. The cleaning head housing 2 further includes a side cover assembly 7 for blocking the sewage guiding and exhaust channel to prevent the air pressure when the sewage is guided to the sewage chamber and the cleaning liquid mixed with bubbles from leaking through the left side wall 20a.

[0101] Further, referring to Figure 2 , Figure 3As shown, a cleaning tank (not shown in the drawings) connecting the left side wall 20a and the right side wall 20b is provided at the upper front end of the floor washer mop head housing body 20. One end face of the cleaning tank faces the outer surface of the cleaning roller 4. An extrusion strip (not shown in the drawings) elastically abutting against the outer surface of the cleaning roller 4 is provided on this end face. A filtering device (not shown in the drawings) integral with the entire cleaning tank is provided in other areas outside the extrusion strip on this end face. The cleaning tank communicates with the two side walls of the floor washer mop head housing body 20. A first sewage outlet 204a and a second sewage outlet 204b are provided in the area of the left side wall 20a communicating with the cleaning tank. These two sewage outlets are collectively referred to as the sewage outlet 204. When the floor washer is working, the cleaning roller 4 rotates, and the clear water scouring the outer surface of the cleaning roller 4 is transformed into sewage after being squeezed by the extrusion strip, passes through the filtering device, and then flows into the sewage guiding and exhaust channel along the channel of the cleaning tank through the first sewage outlet 204a and the second sewage outlet 204b.

[0102] In this embodiment, as Figure 2 , Figure 4As shown, the water tank 1 is an integrated water tank. The water tank 1 is connected to the cleaning roller 4 through a water delivery pipeline. The water delivery pipeline includes a clear water suction pipe 21 that sucks clear water from the clear water outlet 11 of the water tank 1 and a clear water delivery pipe 22 that delivers clear water to the cleaning tank on the surface of the cleaning roller. The other end of the clear water suction pipe 21 is connected to the suction port of a water pump (not shown in the figure), and the other end of the clear water delivery pipe 22 is connected to the water outlet of the water pump. The end of the integrated water tank 1 that is docked with a side wall of the floor washer head housing 2 is provided with a clear water outlet 11 and a sewage inlet 12. A sewage guiding channel N for recovering sewage to the surface of the cleaning roller is also provided on a side wall of the floor washer head housing 2. The sewage guiding channel N is a section of the sewage guiding and exhaust channel dedicated to guiding sewage and is a part of the sewage guiding and exhaust channel. The part of the sewage guiding and exhaust channel except the sewage guiding channel N is all the exhaust channel M. Further, the exhaust channel M can surround the sewage guiding channel N. One end of the sewage guiding channel N communicates with the sewage outlet 204 of the cleaning tank, and the other end of the sewage guiding channel N communicates with a sewage return port 205 that communicates with the sewage chamber of the integrated water tank 1. The sewage return port 205 communicates with the sewage inlet 12 of the integrated water tank 1. An exhaust port 207 is provided in the area corresponding to the outer surface of the cleaning roller 4 within the exhaust channel M on the side wall. On the front side walls of the floor washer head housing 2, a gas dispersing channel (not shown in the figure) parallel to the cleaning tank is also connected. The cleaning tank and the gas dispersing channel are actually an integrated lying "S"-shaped crossbeam (not shown in the figure) connecting the two side walls. The opening of the cleaning tank faces upward away from the cleaning roller 4. A detachable cleaning tank sealing cover (not shown in the figure) for sealing the cleaning tank is provided at the opening of the cleaning tank. The opening of the gas dispersing channel faces the upper surface of the cleaning roller 4. The air discharged after the sewage enters the sewage chamber along the sewage guiding channel N is discharged into the gas dispersing 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 chamber. In this way, the cleaning liquid with bubbles in the sewage chamber can continue to defoam on its own until all the bubbles naturally dissipate when the pressure inside and outside the sewage chamber is balanced.

[0103] In this embodiment, as Figure 10 , Figure 11 shown, the cleaning head housing body 20 further includes an integrated crossbeam (not shown in the figure) provided between the left side wall 20a and the right side wall 20b. The crossbeam is provided with an n-shaped gas dispersing channel with an opening downward facing the bottom surface of the cleaning roller. The exhaust port 207 communicates the exhaust channel M and the gas dispersing channel.

[0104] In this embodiment, as Figure 2 , Figure 4As shown, a flange 201 forming a closed ring is provided around the circumference of the left side wall 20a of the cleaning head housing body 20. Inside the closed ring on the left side wall 20a, a first convex weir 202 connecting to and forming a closed inner ring with the flange 201 is further provided. The closed inner ring encloses the sewage drainage and exhaust channel. The flange height of the flange 201 extending outward from the housing is flush with the first convex weir 202. An upper section of the flange 201 and the first convex weir 202 together enclose a closed inner ring. The left side wall of the floor washer mop head housing 2, this straight wall ring, and the inner wall of the side cover assembly 7 together enclose the entire sewage drainage and exhaust channel;

[0105] Further, a second convex weir 203 that can form a small closed ring is also provided inside the closed inner ring on the left side wall 20a, as Figure 3 shown. The second convex weir 203 can enclose the sewage drainage channel N together with a part of the first convex weir 202. Of course, as Figure 4 shown, inside the closed inner ring on the left side wall 20a, the second convex weir 203 can also independently enclose the sewage drainage channel N.

[0106] Further, the first convex weir 202 is U-shaped, and its upper two ends are connected to the inner wall of the flange 201.

[0107] The height of the second convex weir 203 is lower than that of 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 inside the entire sewage drainage and exhaust channel. The left side wall 20a of the cleaning head housing body 20, this straight wall inner ring, and the inner wall of the side cover assembly 7 together enclose the sewage drainage channel N.

[0108] Specifically, referring to Figure 5 、 Figure 8 shown, the sewage return side cover 7 is hermetically sealed on the left side wall 20a of the cleaning head housing body 20. When the water tank 1 is inserted into the cleaning head housing body 20 and installed in place, the left end back surface of the straight upper edge of the second convex weir 203 connecting the exhaust channel M and the sewage drainage channel N on the left side wall 20a of the cleaning head housing body 20 elastically abuts against the sewage valve core (not shown in the figure) abutting port (not shown in the figure) of the sewage inlet 12 of the water tank 1. This abutting port opens the sewage channel for sewage to flow from the sewage outlet 204 through the sewage drainage channel N and then through the return sewage port 205 into the sewage inlet 12 and into the sewage chamber. At the same time, this abutting port also opens another exhaust channel for the air in the sewage chamber to be discharged from the sewage inlet 12, connected to the exhaust outlet 206, through the exhaust channel M and then through the exhaust port 207 outside the left side wall 20a of the cleaning head housing body 20.

[0109] Combined with 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] In a specific embodiment, referring to Figure 1 ,Figure 6 As shown, the cleaning head mechanism may further include a water tank 1. The water tank 1 is connected to the cleaning roller 4 through a water delivery pipe, and is used to supply clean water to the cleaning roller 4 and recycle the sewage generated by the cleaning roller 4. The clean water provided by the water tank 1 can moisten the wiping layer on the outer surface of the roller assembly, so that the wiping layer can clean the ground. The cleaning head mechanism wipes the garbage on the ground through the cleaning roller 4, sweeps the garbage adhered to the outer surface of the cleaning roller 4 into the garbage box 9 through the brush assembly 3; recycles the sewage adsorbed by the wiping layer on the surface of the cleaning roller 4 through the integrated water tank 1, and supplies 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 ground cleaning is improved and the cleaning effect is enhanced.
