Description

Technical Field

[0001] The present application relates to the technical field of environmental cleaning appliances, and in particular to a floor brush and cleaning equipment. Background Art

[0002] With the development of science and technology and the improvement of living standards, household cleaning equipment such as vacuum cleaners and floor scrubbers have become increasingly popular and have more and more functions.

[0003] The cleaning device may include a main unit and a floor brush. The negative pressure generated by the main unit may collect dust and other impurities on the floor through the floor brush. The floor brush may include a housing and one or two roller brushes. When the user pushes the floor brush to move on the floor, the roller brush may roll in contact with the floor to absorb dust and impurities on the floor or wet mop the floor. After cleaning the floor, the roller brush needs to be removed from the housing to clean it.

[0004] However, in the related art, the roller brush is detachably connected to the shell by magnetic attraction, and the cost of the magnetic component is relatively high, thereby increasing the cost of the floor brush. Utility Model Content

[0005] Based on this, the present application provides a floor brush and cleaning device to solve the deficiencies in the related art.

[0006] In a first aspect, the present application provides a floor brush, which includes a housing, a roller brush assembly and a connecting assembly, wherein the roller brush assembly includes a roller brush and a handle, wherein the handle is connected to one end of the roller brush, and the other end of the roller brush is rotatably connected to the housing, and the handle is connected to the housing, and the handle has a limiting hole;

[0007] The connecting component comprises a connecting piece, which is elastically connected to the shell so as to be plugged into or disconnected from the limiting hole, and the moving direction of the connecting piece is consistent with the axial direction of the roller brush.

[0008] The floor brush provided in the embodiment of the present application has a shell for installing the roller brush, and a handle piece for connecting one end of the roller brush and the shell, and improves the convenience of disassembling and assembling the roller brush. The handle piece is detachably connected to the shell through the cooperation of the limiting hole and the connecting piece, and the cooperation of the handle piece and the shell, so that the roller brush assembly and the shell are detachably connected, thereby improving the convenience and reliability of disassembling and assembling the roller brush, and reducing the cost of the floor brush.

[0009] In a possible implementation, the handle member has a first limiting portion, the housing has a second limiting portion, and when the connecting member is inserted into the limiting hole, the first limiting portion is clamped into the second limiting portion.

[0010] In this way, when the connecting piece is inserted into the limiting hole, the connecting piece can limit the radial displacement of the handle piece along the roller brush, and further limit the radial displacement of the roller brush itself, and the first limiting portion and the second limiting portion are clamped together to enable the handle piece and the shell to be clamped together, thereby limiting the axial displacement of the handle piece and further limiting the axial displacement of the roller brush itself. The roller brush can be securely mounted on the shell by clamping the handle piece and the shell and inserting the connecting piece into the limiting hole.

[0011] In a possible implementation, the connecting assembly further includes an elastic member, and two ends of the elastic member in the elastic force direction are connected to the connecting member and the shell to drive the connecting member to move toward the outside of the shell.

[0012] In this way, the connecting piece can be elastically connected to the shell through the elastic piece, and the elastic piece can provide elastic force for the connecting piece. When the roller brush is installed to the shell, after the connecting piece is aligned with the limiting hole, the connecting piece can move toward the outside of the shell under the action of the elastic force, so that the connecting piece is inserted into the limiting hole, and when the roller brush is working, the elastic force can prompt the connecting piece to always be reliably inserted into the limiting hole, thereby preventing the roller brush from escaping from the shell due to the connecting piece being separated from the limiting hole.

[0013] In a possible implementation manner, the first limiting portion is a limiting rib, the second limiting portion is a limiting groove, and the limiting rib is clamped in the limiting groove.

[0014] In this way, the handle piece can be clamped to the shell by the limiting rib being clamped to the limiting groove, thereby limiting the displacement of the roller brush assembly along the axial direction of the roller brush.

[0015] In a possible implementation manner, the limiting groove is at least located at the bottom of the shell.

[0016] In this way, when installing the roller brush, the user can apply downward force to conveniently insert the limiting rib into the limiting groove, and then clamp the limiting rib in the limiting groove, and then insert the connecting piece into the limiting hole, so that the handle and the roller brush can be conveniently installed on the shell together.

[0017] In a possible implementation, the connecting member includes a pressing portion and a first clamping portion connected to each other, the shell has a second clamping portion, the first clamping portion is clamped to the second clamping portion, and the pressing portion is used to move toward the inner side of the shell under the drive of external force.

[0018] In this way, when the roller brush needs to be removed, the hand can apply external force to the pressing part, and the external force drives the connecting piece to move toward the inside of the shell, thereby disengaging the connecting piece from the limiting hole, so as to facilitate the subsequent removal of the roller brush from the shell. In addition, since the first clamping part is clamped to the second clamping part, when the external force disappears, even if the connecting piece moves toward the outside of the shell under the action of elastic force, the connecting piece can still remain clamped with the shell, thereby preventing the connecting piece from being detached from the shell.

[0019] In a possible implementation manner, the first clamping portion is a clamping arm, the second clamping portion is a clamping hole, and the clamping arm is clamped in the clamping hole.

[0020] In this way, the connection between the connecting piece and the shell can be realized by the connection arm being connected to the connection hole, and the movement of the connecting piece along the axis direction of the roller brush will not be hindered, and it is ensured that the connecting piece will not be separated from the shell during the movement.

[0021] In a possible implementation, when the roller brush is mounted on the shell, a surface of the connecting member facing away from the shell protrudes from the handle member.

[0022] In this way, when the roller brush is installed on the shell, the connecting piece and the limiting hole can maintain effective connection, thereby preventing the handle piece from being disconnected from the shell. Moreover, when the roller brush is disassembled, the part of the connecting piece protruding from the handle piece can be convenient for the user to press, thereby improving the user's operating convenience.

[0023] In a possible implementation, the shell has an avoidance hole, one end of the connecting member is located inside the shell and connected to the shell, and the other end of the connecting member extends out of the shell through the avoidance hole.

[0024] In this way, one end of the connecting piece is hidden in the shell, which can improve the overall aesthetics of the floor brush, and the other end of the connecting piece extends out of the shell through the avoidance hole to facilitate the connection between the connecting piece and the limiting hole, thereby constraining the handle.

[0025] In a possible embodiment, the shell has a roller brush groove, one side of the roller brush groove along the travel direction of the floor brush has an opening, the opening and the connecting piece are arranged at intervals along the travel direction of the floor brush, and the roller brush is inserted into the roller brush groove through the opening.

[0026] Thus, when installing the roller brush assembly, the roller brush can be inserted into the roller brush groove through the opening, and the end of the roller brush away from the handle is rotated and connected to the housing, and the handle is rotated to the locking position, and the roller brush assembly can be installed on the housing as a whole. When removing the roller brush assembly, the handle is rotated to the unlocking position to release the lock between the handle and the housing, and then the roller brush is pulled out of the roller brush groove, and the roller brush assembly can be removed from the housing.

[0027] In a second aspect, the present application provides a cleaning device, which includes a device host and the floor brush provided in the first aspect, and the floor brush is connected to the device host.

[0028] In addition to the technical problems solved by the embodiments of the present application described above, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions, other technical problems that can be solved by the floor brush and cleaning equipment provided by the present application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0040] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0041] In the description of this application, 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, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0043] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0044] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0045] The cleaning device may include a main unit and a floor brush. The negative pressure generated by the main unit can collect dust and other impurities on the ground through the floor brush. The floor brush may include a housing and one or two roller brushes. When the user pushes the floor brush to move on the ground, the roller brush may roll in contact with the ground to suck away dust and impurities on the ground or wet mop the ground. After cleaning the ground, the roller brush needs to be removed from the housing to clean it. However, in the related art, the roller brush is detachably connected to the housing by magnetic attraction, and the cost of the magnetic component is relatively high, thereby increasing the cost of the floor brush.

[0046] In view of the above problems, an embodiment of the present application provides a floor brush and cleaning device, wherein the connecting piece can limit the displacement of the roller brush along its own radial direction after being plugged into the limiting hole, and the handle piece can limit the displacement of the roller brush along its own axial direction after being connected to the shell, so that the roller brush can be installed on the shell, and the disassembly and assembly is simple and reliable, and the cost is low.

[0047] The specific implementation of the floor brush and cleaning device provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0048] Reference Figures 1 to 4 As shown, the floor brush provided in the embodiment of the present application includes a housing 100, a roller brush assembly 200 and a connecting assembly 300. The roller brush assembly 200 includes a roller brush 210 and a handle 220. The handle 220 is connected to one axial end of the roller brush 210. The other axial end of the roller brush 210 is rotatably connected to the housing 100. The handle 220 is connected to the housing 100. The handle 220 has a limiting hole 221. The connecting assembly 300 includes a connecting member 310. The connecting member 310 is elastically connected to the housing 100 to be plugged into the limiting hole 221 or disconnected from the limiting hole 221. The moving direction of the connecting member 310 is consistent with the axial direction of the roller brush 210.

[0049] In the present application, the housing 100 is used to install the roller brush assembly 200 , the roller brush assembly 200 is used to clean the surface to be cleaned, and the connecting assembly 300 is used to detachably connect the roller brush assembly 200 and the housing 100 .

[0050] Specifically, the roller brush assembly 200 may include a roller brush 210 and a handle piece 220. One end of the roller brush 210 may be rotatably connected to the handle piece 220. The handle piece 220 may be detachably connected to the shell 100. The handle piece 220 may improve the convenience of disassembling and assembling the roller brush 210. The other end of the roller brush 210 may be rotatably connected to the shell 100. In this way, both ends of the roller brush 210 are rotatably arranged relative to the shell 100 to facilitate the roller brush 210 to roll in contact with the surface to be cleaned.

[0051] The connecting component 300 may include a connecting piece 310, which can be moved relative to the shell 100 along the axial direction of the roller brush 210 under the action of elastic force. The handle piece 220 has a limiting hole 221. When the connecting piece 310 moves toward the limiting hole 221 along the axial direction of the roller brush 210 under the action of elastic force, the connecting piece 310 can be inserted into the limiting hole 221, so that the connecting piece 310 can limit the radial displacement of the roller brush assembly 200 along the roller brush 210 after cooperating with the limiting hole 221. At the same time, after the handle piece 220 is connected to the shell 100, the axial displacement of the roller brush assembly 200 can be limited. In this way, the roller brush assembly 200 can be reliably installed to the shell 100. When the connecting piece 310 moves away from the limiting hole 221 along the axial direction of the roller brush 210 under the action of external force, the connecting piece 310 can be disengaged from the limiting hole 221, thereby releasing the radial constraint of the roller brush assembly 200 along the roller brush 210. Afterwards, the handle piece 220 is disengaged from the shell 100, and the axial constraint of the roller brush assembly 200 along the roller brush 210 can be released. In this way, the roller brush assembly 200 can be easily removed from the shell 100.

[0052] Compared with the related art that uses magnetic attraction to detachably connect the roller brush 210 and the shell 100, the embodiment of the present application can conveniently disassemble and assemble the roller brush 210 through the cooperation of the connecting piece 310, the handle piece 220 and the shell 100, which not only eliminates the magnetic component and reduces the cost of the floor brush, but also the mechanical connection method is more stable and reliable, and can avoid the problem of being unable to connect due to demagnetization of the magnetic component.

[0053] It should be noted that the floor brush may have one or two roller brushes 210, which is not limited in the present embodiment. When the floor brush has two roller brushes 210, the two roller brushes 210 may be connected to a handle 220, which is then connected to the housing 100, and the two roller brushes 210 are installed together to the housing 100, or the two roller brushes 210 may be connected to two handles 220, which are then connected to the housing 100, and the two roller brushes 210 are installed to the housing 100.

[0054] The floor brush provided in the embodiment of the present application includes a housing 100, a roller brush assembly 200 and a connecting assembly 300. The roller brush assembly 200 includes a roller brush 210 and a handle 220. The handle 220 includes a limiting hole 221. The connecting assembly 300 includes a connecting piece 310. The housing 100 is provided for installing the roller brush 210, the handle 220 is provided for connecting one end of the roller brush 210 and the housing 100, and the convenience of disassembling and assembling the roller brush 210 is improved. The limiting hole 221 cooperates with the connecting piece 310, and the handle 220 cooperates with the housing 100, so that the handle 220 is detachably connected to the housing 100, and then the roller brush assembly 200 and the housing 100 are detachably connected, thereby improving the convenience and reliability of disassembling and assembling the roller brush 210 and reducing the cost of the floor brush.

[0055] Reference Figures 3 to 6 As shown, in a possible implementation, the handle 220 has a first limiting portion 222 , the housing 100 has a second limiting portion 110 , and when the connecting member 310 is inserted into the limiting hole 221 , the first limiting portion 222 is snap-fitted into the second limiting portion 110 .

[0056] It can be understood that when the connecting member 310 is inserted into the limiting hole 221, the connecting member 310 can limit the radial displacement of the handle member 220 along the roller brush 210, and further limit the radial displacement of the roller brush 210, and the first limiting portion 222 is engaged with the second limiting portion 110 to engage the handle member 220 and the shell 100, thereby limiting the axial displacement of the handle member 220 and further limiting the axial displacement of the roller brush 210, and thus, after the handle member 220 is engaged with the shell 100 and the connecting member 310 is inserted into the limiting hole 221, the roller brush 210 can be securely mounted on the shell 100.

[0057] When the roller brush 210 needs to be removed, the handle 220 can be rotated along the circumference of the roller brush 210, so that the first limiting portion 222 and the second limiting portion 110 are disengaged, and the connecting member 310 and the limiting hole 221 are disengaged, and then the roller brush 210 can be easily removed from the shell 100.

[0058] Exemplarily, one of the first limiting portion 222 and the second limiting portion 110 is a limiting rib, and the other is a limiting groove. The limiting rib is engaged with the limiting groove, so that the handle 220 is engaged with the housing 100 .

[0059] Reference Figure 3 and Figure 6 As shown, in some embodiments, the connection assembly 300 further includes an elastic member 320 , and both ends of the elastic member 320 in the elastic direction are connected to the connection member 310 and the shell 100 to drive the connection member 310 to move toward the outside of the shell 100 .

[0060] With such a configuration, the connecting member 310 can be elastically connected to the shell 100 through the elastic member 320, and the elastic member 320 can provide elastic force for the connecting member 310. When the roller brush 210 is installed to the shell 100, after the connecting member 310 is aligned with the limiting hole 221, the connecting member 310 can move toward the outside of the shell 100 under the action of the elastic force, so that the connecting member 310 is inserted into the limiting hole 221, and when the roller brush 210 is working, the elastic force can prompt the connecting member 310 to always be reliably inserted into the limiting hole 221, thereby preventing the roller brush 210 from escaping from the shell 100 due to the connecting member 310 being separated from the limiting hole 221.

[0061] In a specific implementation, the first limiting portion 222 is a limiting rib, the second limiting portion 110 is a limiting groove, and the limiting rib is clamped in the limiting groove. In this way, the handle 220 can be clamped in the housing 100 by clamping the limiting rib in the limiting groove, thereby limiting the displacement of the roller brush assembly 200 along the axial direction of the roller brush 210.

[0062] In a possible implementation, the limiting groove is at least located at the bottom of the housing 100, or the limiting groove extends from the bottom of the housing 100 to the side of the housing 100. Correspondingly, the limiting rib can be located at the outer edge of the handle 220 corresponding to the limiting groove, so that when installing the roller brush 210, the user can apply force downward to conveniently insert the limiting rib into the limiting groove, and then clamp the limiting rib in the limiting groove, and then insert the connecting member 310 into the limiting hole 221, so that the handle 220 and the roller brush 210 can be conveniently installed on the housing 100 together.

[0063] Reference Figure 3 and Figure 6 As shown, in a specific implementation, the connecting member 310 includes a pressing portion 311 and a first clamping portion 312 that are connected to each other, the shell 100 has a second clamping portion 120, the first clamping portion 312 is clamped to the second clamping portion 120, and the pressing portion 311 is used to move toward the inner side of the shell 100 under the drive of external force.

[0064] That is, when the roller brush 210 needs to be removed, the hand can apply external force to the pressing portion 311, and the external force drives the connecting member 310 to move toward the inner side of the housing 100, thereby disengaging the connecting member 310 from the limiting hole 221, so as to facilitate the subsequent removal of the roller brush 210 from the housing 100. Since the first clamping portion 312 is clamped to the second clamping portion 120, when the external force disappears, even if the connecting member 310 moves toward the outer side of the housing 100 under the action of the elastic force, the connecting member 310 can still be clamped with the housing 100, thereby preventing the connecting member 310 from being disengaged from the housing 100.

[0065] In a possible implementation, the first clamping portion 312 is a clamping arm, the second clamping portion 120 is a clamping hole, and the clamping arm is clamped to the clamping hole. Thus, the clamping of the connecting member 310 and the housing 100 can be achieved by clamping the clamping arm to the clamping hole, and the movement of the connecting member 310 along the axis direction of the roller brush 210 will not be hindered, and it is ensured that the connecting member 310 will not be separated from the housing 100 during the movement, that is, the connecting member 310 can move toward the outside of the housing 100 along the axis direction of the roller brush 210 under the action of elastic force, and can also move toward the inside of the housing 100 along the axis direction of the roller brush 210 under the action of external force.

[0066] For example, the pressing portion 311 may be columnar, and there may be two clamping arms, which may be arranged at intervals along the circumference of the pressing portion 311 . Correspondingly, two clamping holes may be provided on the shell 100 to improve the connection reliability between the two.

[0067] In a possible implementation, when the roller brush 210 is installed on the housing 100 , the surface of the connecting member 310 facing away from the housing 100 protrudes from the handle member 220 .

[0068] Such a configuration can ensure that when the roller brush 210 is installed on the shell 100, the connecting piece 310 and the limiting hole 221 remain effectively connected, thereby preventing the handle piece 220 from being disconnected from the shell 100. In addition, when the roller brush 210 is disassembled, the part of the connecting piece 310 protruding from the handle piece 220 can be convenient for the user to press, thereby improving the user's operating convenience.

[0069] Reference Figure 3 As shown, in a possible implementation, the housing 100 has an avoidance hole 130 , one end of the connecting member 310 is located inside the housing 100 and connected to the housing 100 , and the other end of the connecting member 310 extends out of the housing 100 through the avoidance hole 130 .

[0070] It can be understood that one end of the connecting member 310 is hidden in the shell 100, which can improve the overall aesthetics of the floor brush. The other end of the connecting member 310 extends out of the shell 100 through the avoidance hole 130 to facilitate the connection between the connecting member 310 and the limiting hole 221, thereby constraining the handle 220.

[0071] It should be noted that the shell 100 may include a bottom shell 100a and an upper cover 100b, the upper cover 100b is connected to the bottom shell 100a, wherein the bottom shell 100a and the upper cover 100b both have a semicircular groove, the openings of the two semicircular grooves are relatively arranged to jointly define an avoidance hole 130, and the limit groove is located in the bottom shell 100b.

[0072] In a possible implementation, the housing 100 has a roller brush groove 140 , and one side of the roller brush groove 140 along the travel direction of the floor brush has an opening. The opening and the connecting member 310 are arranged at intervals along the travel direction of the floor brush, and the roller brush 210 is inserted into the roller brush groove 140 through the opening.

[0073] In this way, when installing the roller brush assembly 200, the roller brush 210 can be inserted into the roller brush groove 140 through the opening, and the end of the roller brush 210 away from the handle 220 is rotated and connected to the housing 100, and the handle 220 is rotated to the locking position, and then the first limiting portion 222 is clamped to the second limiting portion 110, and the connecting member 310 is inserted into the limiting hole 221, and the roller brush assembly 200 can be installed as a whole to the housing 100. When disassembling the roller brush assembly 200, the handle 220 is rotated to the unlocking position to release the lock between the handle 220 and the housing 100, and then the roller brush 210 is pulled out from the roller brush groove 140, and the roller brush assembly 200 can be disassembled from the housing 100.

[0074] In addition, an embodiment of the present application also provides a cleaning device, which includes a device host and a floor brush provided in the aforementioned embodiment. The floor brush is connected to the device host, and the device host can provide suction for the floor brush to assist the floor brush in sucking away dust and impurities from the surface to be cleaned.

[0075] Among them, the structure and working principle of the floor brush have been described in detail in the above embodiments, and will not be repeated here. It should be noted that the cleaning equipment can be a vacuum cleaner, a floor scrubber or a sweeping robot, etc., and the embodiments of the present application are not limited to this.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
