Description
Technical Field
[0001] The present invention relates to the technical field of cleaning equipment, and particularly to a floor brush of a vacuum cleaner and a vacuum cleaner. Background Art
[0002] With the development of technology, as one of the cleaning equipment, vacuum cleaners have become more and more popular. The working principle of a vacuum cleaner is that through the high-speed operation of the vacuum cleaner motor, dust enters the interior of the vacuum cleaner together with air and is filtered by the dust filtering component, and the filtered air is then released back into the environment to improve the environment and enhance the comfort and air quality.
[0003] For some existing vacuum cleaners, vacuuming and mopping are combined. The mop is wound around the rotating shaft of the vacuum cleaner to form a combined vacuum cleaner. Such a combined vacuum cleaner has, in addition to the general vacuuming function, a mopping function. The mop is in direct contact with the ground, and the gaps around the mop are communicated with the suction port of the vacuum cleaner. When cleaning the ground, not only can the dust on the ground be sucked in through the vacuuming function, but also the stains adhering to the ground that are difficult to be sucked away can be cleaned by the mop, improving the cleaning ability and cleaning effect of the vacuum cleaner.
[0004] However, for the existing combined vacuum cleaners, since the rotating shaft of the vacuum cleaner is fixed to the vacuum cleaner and the mop part is located inside the housing of the vacuum cleaner, it is inconvenient to clean the mop. Summary of the Invention
[0005] The present invention provides a floor brush of a vacuum cleaner and a vacuum cleaner, wherein at least part of the mop of the vacuum cleaner can be separated from the housing of the vacuum cleaner, facilitating the cleaning of the mop.
[0006] To achieve the above object, in a first aspect, the present invention provides a floor brush of a vacuum cleaner, including a housing, a driving assembly, and a cleaning assembly disposed in the inner cavity of the housing. The cleaning assembly includes a support frame, an annular cleaning belt, and two transmission shafts. The two transmission shafts are arranged side by side and spaced apart on bearings in the support frame, the cleaning belt is wound around the two transmission shafts, the driving assembly is connected to the first transmission shaft, and the driving assembly drives the cleaning belt to rotate through the transmission shaft;
[0007] The support frame is connected to the housing. When the support frame is disconnected from the housing, the support frame rotates around the housing so that the second transmission shaft in the cleaning assembly extends out of the housing.
[0008] In this way, when it is necessary to clean the cleaning belt, the position where the support frame is disengaged from the housing is set. At this time, the first transmission shaft rotates around the housing, and the support frame rotates around the first transmission shaft so that the second transmission shaft in the cleaning assembly extends out of the housing, and the second transmission shaft drives part of the cleaning belt to extend out of the housing, thereby cleaning the cleaning belt. At least part of the cleaning belt of the vacuum cleaner can be separated from the housing of the vacuum cleaner, so that it is convenient to clean the cleaning belt and improves the user experience.
[0009] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the drive assembly includes a driving member, a driven wheel, and a driving wheel connected to the driving member. The driving member is connected to the housing. One end of the first transmission shaft passes through the support frame and is connected to the driven wheel. The driven wheel meshes with the driving wheel. The driving member drives the driven wheel to rotate through the driving wheel. In this way, the entire support frame can be removed from the housing, facilitating the cleaning of the cleaning belt.
[0010] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the drive assembly further includes a connecting member and a main shaft. The driving member and the driving wheel are connected through the connecting member. The main shaft is connected to the housing. The driving wheel is sleeved on the main shaft. In this way, the space occupied by the driving member on the support frame is avoided, so as to increase the axial length of the cleaning belt along the transmission shaft.
[0011] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the driven wheel is inserted into the driving wheel, and the axis of rotation of the driven wheel is collinear with the axis of rotation of the driving wheel. In this way, space can be further saved.
[0012] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the driving wheel has a tapered receiving groove. The receiving groove has tapered internal teeth. The driven wheel is inserted into the receiving groove. The driven wheel has tapered external teeth that match the internal teeth. In this way, it is convenient to insert the driven wheel into the driving wheel.
[0013] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the main shaft has a connecting portion and a resisting portion connected to the connecting portion. The connecting portion passes through the bottom wall of the receiving groove and is connected to the housing. The resisting portion is located between the end of the driven wheel in the receiving groove and the bottom wall of the receiving groove. In this way, when the driving wheel is working, the movement position of the resisting portion is restricted by the end of the driven wheel in the receiving groove, avoiding the connecting portion from detaching from the housing.
[0014] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the drive assembly further includes a washer. The washer is sleeved on the connecting portion. The washer is located between the resisting portion and the bottom wall of the receiving groove. In this way, it is avoided that the resisting portion adsorbs on the bottom wall of the receiving groove, so as to smoothly pull out the main shaft from the receiving groove.
[0015] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the outer side wall of the support frame has an extension portion. The extension portion and the driven wheel are respectively located at opposite ends of the first transmission shaft. The extension portion is rotatably connected to the housing. In this way, the support frame rotates more smoothly around the housing.
[0016] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the housing is provided with a fixing component, the housing is provided with an arc-shaped supporting portion, a part of the extending portion is located inside the supporting portion, the fixing component covers the supporting portion, and the fixing component and the supporting portion together define a receiving cavity for the extending portion to rotate. In this way, it is convenient to disassemble the support frame.
[0017] As an alternative, for the floor brush of the vacuum cleaner provided by the embodiments of the present invention, the fixing component is detachably connected to the housing. In this way, by the detachable connection between the fixing component and the housing, it is convenient to disassemble the support frame.
[0018] In a second aspect, the present invention further provides a vacuum cleaner, including a vacuum cleaner body and the floor brush of the above-mentioned vacuum cleaner connected to the vacuum cleaner body.

[0038] Figure 1 Schematic structural diagram of a floor brush of a vacuum cleaner provided by an embodiment of the present invention; Figure 2 Exploded view of a floor brush of a vacuum cleaner provided by an embodiment of the present invention; Figure 3 Bottom view of a floor brush of a vacuum cleaner provided by an embodiment of the present invention; Figure 4 is Figure 1 Cross-sectional view taken along A-A in Figure 5 is Figure 4 Cross-sectional view taken along B-B in Figure 6 is Figure 5 Local enlarged view at C in Figure 7 is Figure 4 Cross-sectional view taken along D-D in Figure 8 Schematic structural diagram of a drive assembly in a floor brush of a vacuum cleaner provided by an embodiment of the present invention; Figure 9 Schematic structural diagram of a cleaning assembly in a floor brush of a vacuum cleaner provided by an embodiment of the present invention. Refer to FIGS. 1 to Figure 9As shown in the figure, an embodiment of the present invention provides a floor brush of a vacuum cleaner, which includes a housing 10, a driving assembly 20, and a cleaning assembly 30 disposed in the inner cavity of the housing 10. The cleaning assembly 30 includes a support frame 31, an annular cleaning belt 32, and two transmission shafts 33. The two transmission shafts 33 are arranged side by side and spaced apart on bearings 312 in the support frame 31. The cleaning belt 32 is wound around the two transmission shafts 33. The driving assembly 20 is connected to the first transmission shaft 33, and the driving assembly 20 drives the cleaning belt 32 to rotate through the transmission shaft 33.
[0039] The support frame 31 is connected to the housing 10. When the support frame 31 is disconnected from the housing 10, the support frame 31 rotates around the housing 10, so that the second transmission shaft 33 in the cleaning assembly 30 partially extends out of the housing 10.
[0040] Specifically, the housing 10 can be a hollow box body. The cleaning assembly 31 is disposed inside the box body. In order to facilitate mopping the floor with the cleaning assembly 31, an opening is provided at the bottom of the box body, and a part of the cleaning assembly 31 extends out of the box body through the opening, so that the cleaning assembly 31 can perform mopping operations. Among them, the driving assembly 20 is connected to the housing 10, and the driving assembly 20 is connected to the cleaning assembly 31. The driving assembly 20 drives the cleaning assembly 31 to rotate to realize the mopping operation of the floor brush for vacuuming.
[0041] Among them, the cleaning assembly 30 includes a support frame 31, an annular cleaning belt 32, and two transmission shafts 33. The support frame 31 is used to support the transmission shafts 33. The two ends of the transmission shafts 33 are respectively connected to the opposite ends of the support frame 31. The two transmission shafts 33 are arranged side by side and spaced apart. The cleaning belt 32 is wound around the two transmission shafts 33. The cleaning belt 32 is supported by the two transmission shafts 33, and at the same time, the contact area between the cleaning belt 32 and the ground is increased, so that when the floor brush of the vacuum cleaner is working, it makes surface contact with the ground, improving the mopping efficiency.
[0042] When the cleaning belt 32 is mopping the floor, the cleaning belt 32 is driven to rotate by the cleaning assembly 30. Specifically, the driving assembly 20 is connected to any one of the two transmission shafts 33. For the convenience of description, the transmission shaft 33 connected to the driving assembly 20 is hereinafter referred to as the first transmission shaft 33. The driving assembly 20 is connected to the first transmission shaft 33, and the driving assembly 20 drives the first transmission shaft 33 to rotate. When the first transmission shaft 33 rotates, it drives the cleaning belt 32 to rotate. After the cleaning belt 32 rotates, it drives the second transmission shaft 33 to rotate, so that the cleaning belt 32 can perform mopping operations smoothly.
[0043] When the cleaning belt 32 performs mopping operations, the support frame 31 is connected to the housing 10. At the same time, the first transmission shaft 33 is connected to the housing 10 to fix the cleaning assembly 30 within the housing 10. When it is necessary to clean the cleaning belt 32, the support frame 31 is disengaged from the housing 10. At this time, the first transmission shaft 33 rotates around the housing 10, and the support frame 31 rotates around the first transmission shaft 33, so that the second transmission shaft 33 in the cleaning assembly 30 extends out of the housing 10, and the second transmission shaft 33 drives a part of the cleaning belt 32 to extend out of the housing 10, thereby cleaning the cleaning belt 32. At least a part of the cleaning belt 32 of the vacuum cleaner can be detached from the housing 10 of the vacuum cleaner. In this way, it is convenient to clean the cleaning belt 32 and the user experience is improved.
[0044] Among them, the connection between the support frame 31 and the housing 10 can be achieved in various ways. In one possible implementation, the housing 10 has through holes, and the support frame 31 has connection holes opposite to the through holes. The support frame 31 and the housing 10 are connected by inserting a pin shaft into the through holes and the connection holes in sequence. Among them, at least two through holes and the connection holes opposite to the through holes can be correspondingly arranged to stably support the cleaning assembly 30 within the housing 10. When it is necessary to clean the cleaning belt 32, the pin shaft is pulled out to disengage the support frame 31 from the housing 10. To prevent the pin shaft from being lost, the pin shaft can be connected to the housing 10 through a connecting wire, or a positioning portion is provided on the pin shaft. When the pin shaft is inserted into the through holes and the connection holes in sequence to connect the support frame 31 and the housing 10, the positioning portion is located between the support frame 31 and the housing 10. When the pin shaft is pulled out, the positioning portion abuts against the inner side wall of the housing 10 to prevent the pin shaft from falling off.
[0045] Among them, there is no limitation on the positions of the through holes on the housing 10 and the connection holes on the support frame 31, as long as they can jointly and stably support the cleaning assembly 30 with the first transmission shaft 33.
[0046] In another possible implementation, at least two support rods are provided on the housing 10. The support rods can rotate around the housing 10. When the support rods rotate to the ends of the support frame 31, the support frame 31 is supported by the support rods to stably support the cleaning assembly 30 within the housing 10. When it is necessary to clean the cleaning belt 32, the support rods are rotated to disengage the support rods from the position of supporting the support frame 31. Among them, the way of rotatably connecting the support rods and the housing 10 can adopt the prior art methods of connecting the support rods and the housing 10 through screws or pin shafts, etc.
[0047] Among them, the support frame 31 and the housing 10 can also be connected by other methods well-known to those skilled in the art, and this embodiment does not limit this here.
[0048] Furthermore, for the convenience of cleaning the cleaning belt 32, the entire support frame 31 can also be removed from the housing 10. See Figures 4 to 6, Figure 8 and Figure 9 As shown, the floor brush of the vacuum cleaner provided in an embodiment of the present invention, the driving assembly 20 includes a driving member 21, a driven wheel 23 and a driving wheel 22 connected to the driving member 21, the driving member 21 is connected to the shell 10, one end of the first transmission shaft 33 passes through the support frame 31 and is connected to the driven wheel 23, the driven wheel 23 is meshed with the driving wheel 22, and the driving member 21 drives the driven wheel 23 to rotate through the driving wheel 22.
[0049] Specifically, one end of the first transmission shaft 33 is passed through the support frame 31 so that one end of the first transmission shaft 33 is located outside the support frame 31, and then the driven wheel 23 is connected to the first transmission shaft 33 located outside the support frame 31, and the driven wheel 23 is meshed with the driving wheel 22 of the driving assembly 20. The driving member 21 of the driving assembly 20 drives the driving wheel 22 to rotate, and the driven wheel 23 meshed with the driving wheel 22 rotates to drive the first transmission shaft 33 to rotate. When it is necessary to completely remove the support frame 31 from the housing 10, the support frame 31 is disconnected from the housing 10, and at the same time, the driven wheel 23 is moved to disengage the driven wheel 23 from the driving wheel 22, and the support frame 31 can be removed from the housing 10.
[0050] In a specific implementation, the driving assembly 20 further includes a main shaft 24 and a connecting member 25 . The driving member 21 is connected to the driving wheel 22 via the connecting member 25 . The main shaft 24 is connected to the housing 10 , and the driving wheel 22 is sleeved on the main shaft 24 .
[0051] Specifically, the driving member 21 can be a motor, the connecting member 25 can be a belt, the output shaft of the motor is connected to a pulley, the outer wall of the driving wheel 22 is provided with a groove matching the belt, and the belt is connected in the grooves of the pulley and the driving wheel 22 to connect the motor and the driving wheel 22, so that the motor drives the driving wheel to rotate. The connecting member 25 can be a chain, and the driving member 21 can also be a rotary cylinder, which is not limited in this embodiment. Among them, the main shaft 24 is connected to the housing 10, and the driving wheel 22 on the main shaft 24 is supported by the housing 10.
[0052] In the floor brush of the vacuum cleaner provided in the embodiment of the present invention, the driving member 21 is connected to the driving wheel 22 through the connecting member 25, and the driving member 21 can be arranged at a position of the housing 10 other than the supporting frame 31, so that the driving member 21 and the supporting frame 31 are staggered. In this way, the driving member 21 is prevented from occupying the space of the supporting frame 31, so as to increase the axial length of the cleaning belt 32 along the transmission shaft 33.
[0053] In order to further save space, in some embodiments, the driven wheel 23 is inserted into the driving wheel 22 , and the rotation axis of the driven wheel 23 is colinear with the rotation axis of the driving wheel 22 .
[0054] Specifically, the outer side wall of the driving wheel 22 is connected to the connecting piece 25, the driven wheel 23 is inserted into the driving wheel 22, and the inner side wall of the driving wheel 22 is meshed with the driven wheel 23. Compared with the parallel meshing of the driving wheel 22 and the driven wheel 23, inserting the driven wheel 23 into the driving wheel 22 reduces the space occupied by the driven wheel 23 and the driving wheel 22.
[0055] Figure 10 This is a schematic diagram of the structure of a driven wheel in a floor brush of a vacuum cleaner provided by an embodiment of the present invention. Figures 4 to 10 As shown, in order to facilitate the connection between the driven wheel 23 and the driving wheel 22. In a specific implementation, the driving wheel 22 has a conical receiving groove 221, and the receiving groove 221 has conical internal teeth. The driven wheel 23 is inserted into the receiving groove 221, and the driven wheel 23 has conical external teeth 231 matching the internal teeth.
[0056] Specifically, the receiving groove 221 is set to be conical, and the size of the opening of the receiving groove 221 is larger than the size of the bottom of the receiving groove 221. At the same time, the driven wheel 23 is also set to be conical, and the size of the end of the driven wheel 23 facing the receiving groove 221 is smaller than the size of the end of the driven wheel 23 away from the receiving groove 221. In this way, it is convenient to insert the driven wheel 23 into the driving wheel 22.
[0057] See also Figures 4 to 6 , Figure 9 and Figure 10 As shown, the driving wheel 22 is sleeved on the main shaft 24, in order to facilitate the connection and removal of the driving wheel 22. Optionally, in the floor brush of the vacuum cleaner provided in the embodiment of the present invention, the main shaft 24 has a connecting portion 241 and a blocking portion 242 connected to the connecting portion 241, the connecting portion 241 passes through the bottom wall of the accommodating groove 221 and is connected to the housing 10, and the blocking portion 242 is located between the end of the driven wheel 23 located in the accommodating groove 221 and the bottom wall of the accommodating groove 221.
[0058] Specifically, the main shaft 21 can be a stepped shaft, which includes a connecting portion 241 and a resisting portion 242 of different diameters. The diameter of the resisting portion 242 is larger than the diameter of the connecting portion 241. The connecting portion 241 passes through the bottom wall of the receiving groove 221 and is inserted into the through hole on the housing 10. The resisting portion 242 is in the receiving groove 221, and the resisting portion 242 is located between the end of the driven wheel 23 located in the receiving groove 221 and the bottom wall of the receiving groove 221. When the driving wheel 22 is working, the moving position of the resisting portion 242 is limited by the end of the driven wheel 23 located in the receiving groove 221 to prevent the connecting portion 241 from being separated from the housing 10. When disassembling the driving wheel 22, after moving the support frame 31, the main shaft 21 can be pulled out of the receiving groove 221.
[0059] In order to smoothly pull out the main shaft 21 from the accommodation groove 221 and prevent the blocking portion 242 from adsorbing on the bottom wall of the accommodation groove 221, for the floor brush of the vacuum cleaner provided by the embodiment of the present invention, the driving assembly 20 further includes a washer 26. The washer 26 is sleeved on the connecting portion 241, and the washer 26 is located between the blocking portion 242 and the bottom wall of the accommodation groove 221. By interposing the washer 26 between the blocking portion 242 and the bottom wall of the accommodation groove 221, it is convenient to pull out the main shaft 21 from the accommodation groove 221.
[0060] In order to make the support frame 31 rotate more smoothly around the housing 10. In some embodiments, the outer side wall of the support frame 31 has an extension portion 311. The extension portion 311 and the driven wheel 23 are respectively located at opposite ends of the first transmission shaft 33, and the extension portion 311 is rotatably connected to the housing 10.
[0061] Specifically, one end of the first transmission shaft 33 passes through the support frame 31 and is connected to the driving wheel 22 through the driven wheel 23. An extension portion 311 is provided on the support frame 31 corresponding to the other end of the first transmission shaft 33. The extension portion 311 extends in a direction away from the outer side wall of the support frame 31, and the extension portion 311 is rotatably connected to the housing 10. In this way, one end of the support frame 31 is rotatably connected to the housing 10, and the other end of the support frame 31 is rotatably connected to the housing 10 through the driven wheel 23 and the driving wheel 22, making the support frame 31 rotate more smoothly around the housing 10.
[0062] In order to facilitate the disassembly of the support frame 31. Further, for the floor brush of the vacuum cleaner provided by the embodiment of the present invention, the housing 10 has a fixing component 112. The housing 10 has an arc-shaped support portion 111. The extension portion 311 is partially located in the support portion 111. The fixing component 112 covers the support portion 111, and the fixing component 112 and the support portion 111 together define an accommodation cavity for the extension portion 311 to rotate.
[0063] Among them, the fixing component 112 is detachably connected to the housing 10.
[0064] Specifically, the fixing component 112 may include a fixing member and a connecting screw connected to the fixing member, or a buckle located on the fixing member. The fixing member has an arc-shaped support surface matching the arc-shaped support portion 111. The support surface and the support portion 11 together define a circular accommodation cavity matching the outer shape of the extension portion 311. When installing the support frame 31, the extension portion 311 is placed in the support portion 111, and then the fixing member is covered, and the fixing member is connected to the housing 10 through the connecting screw or the buckle. When disassembling the support frame 31, the connecting screw is removed to release the connection between the fixing member and the housing 10, so as to take out the support member 31. Or the buckle is disengaged from the position where it is engaged with the housing 10 to release the connection between the fixing member and the housing 10, so as to take out the support member 31.
[0065] In this embodiment, the drive shaft 33 can be a hollow shaft. The drive shaft 33 includes a tubular shaft body and connecting heads 332 connected to both ends of the shaft body. The connecting shaft 331 is inserted into the connecting head 332, and the connecting shaft 331 is coaxial with the shaft body. A part of the connecting shaft 331 extends out of the connecting head 332 and is connected to the support frame 31. While any part of the connecting shaft 331 extends out of the connecting head 332 and is connected to the support frame 31, a driven wheel 23 is also sleeved thereon. Wherein, the diameter of the connecting shaft 331 is smaller than that of the shaft body. The connecting head 332 is provided with a stop portion 333, and the stop portion 333 extends out of the shaft body and abuts against the end of the shaft body to prevent the connecting head 332 from entirely extending into the shaft body.
[0066] The drive shaft 33 can also be a solid shaft. Both ends of the drive shaft 33 have connecting shafts 331 extending out of the drive shaft 33. The driven wheel 23 is connected to the connecting shaft 331. A groove is provided on the outer side wall of the drive shaft 33, and a protrusion matching the groove is provided on the cleaning belt 32. The protrusion is inserted into the groove to prevent the cleaning belt 32 from moving out of the support frame 31. Optionally, the connecting shaft 331 and the drive shaft 33 are integrally formed.
[0067] Wherein, in order to make the drive shaft 33 rotate more smoothly, a bearing 312 is provided at the connection between the drive shaft 33 and the housing 10. Specifically, there are at least four bearing grooves in the support frame 31, and each bearing groove is provided with a bearing 312, and each bearing 312 is sleeved on the drive shaft 33.
[0068] Optionally, each bearing 312 is sleeved on the connecting shaft 331, wherein the diameter of the connecting shaft 331 is smaller than that of the drive shaft 33.
[0069] The embodiment of the present invention also provides a vacuum cleaner, including a vacuum cleaner body and the floor brush of the vacuum cleaner provided in the above embodiment.
[0070] Wherein, the floor brush of the vacuum cleaner is connected to the vacuum cleaner body. The structure and working principle of the floor brush of the vacuum cleaner have been described in detail in the above embodiment, and will not be elaborated here one by one.
[0071] Wherein, the vacuum cleaner body further includes conventional components such as a power source, a connecting wire, a blower, etc. for realizing the vacuuming function of the vacuum cleaner, which are not limited in this embodiment.
[0072] The vacuum cleaner provided in this embodiment is configured such that when the floor brush of the vacuum cleaner is in operation for mopping the floor, the support frame 31 is connected to the housing 10. At the same time, the first transmission shaft 33 is connected to the housing 10 to fix the cleaning assembly 30 within the housing 10. When it is necessary to clean the cleaning belt 32, the support frame 31 is disconnected from the housing 10. At this time, the first transmission shaft 33 rotates around the housing 10, and the support frame 31 rotates around the first transmission shaft 33, causing the second transmission shaft 33 in the cleaning assembly 30 to extend out of the housing 10. The second transmission shaft 33 drives a part of the cleaning belt 32 to extend out of the housing 10, thereby cleaning the cleaning belt 32. At least a part of the cleaning belt 32 of the vacuum cleaner can be separated from the housing 10 of the vacuum cleaner, which facilitates the cleaning of the cleaning belt 32 and improves the user experience.
[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features. 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 invention.
