The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1-3, the present invention provides a multi-surface contact cleaning roller mechanism, which comprises a cleaning roller 1, a contact wringing strip 4 and a water diversion strip 32 forming a cleaning surface with the surface of the cleaning roller 1, a first pressure plate 2 forming a first contact surface with the surface of the cleaning roller 1 and positioned outside the wringing strip 4, and a second pressure plate 31 forming a second contact surface and positioned between the water diversion strip 32 and the cleaning roller 1.
In order to facilitate the connection and fixation between the first pressing plate 2 and the wringing strip 4, at least one fixing groove is arranged on the wringing strip 4, at least one fixing strip matched with the fixing groove is correspondingly arranged on the first pressing plate 2, and during assembly, the fixing strip is arranged in the fixing groove, so that the movable connection between the first pressing plate 2 and the wringing strip 4 is realized.
In order to provide larger rebound effect and deformation space for the first pressing plate 2, a plurality of first pressing plate variable cavities 23 formed by dividing the elastic pressing strips 21 are arranged between the first pressing plate 2 and the cleaning roller cover plate 5, and in order to achieve better rebound effect, the ground is taken as a horizontal line, and the elastic pressing strips are vertically distributed at intervals in the horizontal plane. The design of the elastic pressing strip 21 can enable the first pressing plate 2 to have larger deformation space, and simultaneously reduce the stress of the cleaning roller 1. After the external force is transmitted to the water squeezing strips 4 through the roller cover plate 5, the external force applied to the water squeezing strips 4 can be effectively dispersed due to the design of the elastic pressing strips, so that the normal work of the cleaning roller 1 cannot be influenced. When the cleaning appliance is used, the first pressing plate 2 is in contact with the surface of the cleaning roller extruded by the water extruding strips 4, and in the process of recovering the extruded surface of the cleaning roller to a free state under the action of the elastic material of the cleaning roller, the structure of the first pressing plate variable cavity 23 of the first pressing plate 2 just absorbs the impact of the surface of the cleaning roller on the cleaning roller cover plate 5. Because the first pressing plate and the water squeezing strips have small height difference or are nearly flush in the embodiment, the surface of the squeezed cleaning roller can be smoothly transited in the process of recovering to a free state under the action of the elastic material of the cleaning roller, and the process of absorbing the impact of the surface of the cleaning roller on the cleaning roller cover plate 5 can not generate noise.
In this embodiment, the second pressing plate 31 and the water bar 32 are integrally formed, the water bar is disposed at one end far away from the cleaning roller, and the second pressing plate is disposed on the other opposite end surface and contacts with the surface of the cleaning roller. In order to provide certain cushion power after the second clamp plate atress, be equipped with at least one deck seal structure's variable cavity 33 between second clamp plate and leading water strip, combine this scheme design, variable cavity 33 is two, distributes respectively in the both ends of second clamp plate, in order to make second clamp plate and clean cylinder surface have great contact surface, the extension that stretches out the leading water strip is outwards extended along clean cylinder surface radian respectively to both sides about the second clamp plate, and this structural design makes the width of leading water strip 3 be less than the width of second clamp plate 5.
As shown in fig. 3, in order to make the whole water-bar assembly 3 'hold' more water at the end pointing to the water-squeezing bar, the extension part of the second pressing plate pointing to the end of the water-squeezing bar has a triangular cross section along the width direction, so that the sewage squeezed out by the water-squeezing bar can be smoothly discharged out of the cleaning roller under the guidance of the water-bar assembly. In order to prevent the cleaning brush 7 from impacting the other end of the water bar assembly (the end of the second pressing plate departing from the water squeezing bar) too much after sliding friction relative to the surface of the cleaning roller, the cross section of the extension part of the end of the second pressing plate departing from the water squeezing bar is triangular along the width direction, so that the brush tip of the cleaning brush 7 can smoothly run along the radian corresponding to the upper surface of the shell and the cleaning brush after the transition of the wedge shape, the impact on the end of the second pressing plate departing from the water squeezing bar of the non-wedge structure is reduced, and the noise generated when the cleaning brush 7 runs is reduced.
As the deformation design of the scheme, the number of the variable chambers 33 of the single-layer sealing structure is more than two, and the variable chambers are uniformly distributed on the contact surface of the second pressing plate 31 and the water bar 32 which are integrally formed, the design is used for enabling the second pressing plate and the surface of the cleaning roller to have a larger contact surface, and meanwhile, more variable chambers 33 are arranged on the contact surface of the second pressing plate 31 and the water bar 32 which are integrally formed, so that the impact of the surface of the cleaning roller on the second pressing plate 31 in the actual use can be further 'absorbed'. As a modified design of the scheme, a variable chamber 33 with a multi-layer sealing structure is arranged between the second pressure plate and the water guide bar, so that more multi-layer variable chambers 33 distributed along the radial direction are arranged on the contact surface of the second pressure plate 31 and the water guide bar 32 which are integrally formed, and the impact of the surface of the cleaning roller on the second pressure plate 31 in actual use can be further absorbed.
In this embodiment, the first pressing plate and the second pressing plate are both in contact with the surface of the cleaning roller, and because the surface of the cleaning roller is made of an elastically deformable material, in order to prevent the hard material from damaging the surface of the cleaning roller, the first pressing plate and the second pressing plate are both made of an elastically deformable material, such as elastic rubber. In order to avoid the phenomenon that the stress of the surface of the cleaning roller is uneven when the surface of the cleaning roller works is stressed, the load of the rotating shaft is too large, the radial stress is more uniform, the vibration of the cleaning roller, which deviates from the axis, is generated in the high-speed rotation process, the first pressing plate and the second pressing plate are respectively arc-shaped along the cross section of the width direction, the arc-shaped design can effectively enable the first pressing plate and the second pressing plate to be more tightly attached to the cleaning roller, two contact surfaces are formed in the circumferential direction of the cleaning roller in a dispersing mode, the radial acting force generated between the cleaning surface and the cleaning surface is effectively dispersed when the cleaning surface is cleaned, the stress of the rotating shaft of the cleaning roller is uniform in the circumferential direction, and the vibration of the cleaning roller, which deviates from the axis, is generated in the high-speed rotation process.
In order to avoid the phenomenon that when the surface of the cleaning roller is stressed unevenly, the stress in the vertical direction of the rotating shaft is increased, so that an overlarge load is caused on the rotating shaft, and the vibration of the cleaning roller, which deviates from the shaft center, generated in the high-speed rotation process is reduced, the cleaning roller mechanism further comprises a third pressing plate 6 in interference fit with the surface of the cleaning roller 1, the third pressing plate 6 is in contact with the surface of the cleaning roller, and the surface of the cleaning roller is made of an elastic deformable material, so that the surface of the cleaning roller is prevented from being damaged by hard materials, and the third pressing plate is made of the elastic deformable material. The material that preferred third clamp plate adopted in this scheme is elastic rubber, and in order to make third clamp plate and clean cylinder surface laminating inseparabler, the third clamp plate is the arc design along width direction cross-section, and the third clamp plate sets up many spaced arc shape brace rods (not marked in the figure) along clean cylinder axial, the brace rod is the arc line type of laminating mutually along clean cylinder circumferencial direction and clean cylinder in the cross-section as shown in fig. 1. In this embodiment, through first clamp plate, second clamp plate and three clamp plate three effective cooperation circumferencial direction formation three contact surfaces, effectively disperse the radial effort that produces between the cleaning surface when will clean for the cleaning roller pivot is more even in the circumferencial direction atress, thereby avoids the cleaning roller to produce the vibrations of skew axle center in high-speed rotation.
As shown in figure 2, the first pressure plate and the second pressure plate respectively form an included angle a with the surface contact midpoint which is formed on the surface of the cleaning roller and points to the axis and the axis, and the included angle is 60-180 degrees. When the first pressing plate and the second pressing plate completely face and surround the cleaning roller, the included angle formed by the first pressing plate and the second pressing plate and the surface contact midpoint of the surface of the cleaning roller, which points to the axis, and the axis is 180 degrees. When the total arc length of the first pressure plate and the second pressure plate which are contacted on the surface of the cleaning roller only accounts for 1/3 of the total arc length of the current section of the whole cleaning roller, and the gap between the arc line of the first pressure plate which is contacted with the cleaning roller and the arc line of the second pressure plate which is contacted with the cleaning roller is ignored, the included angle formed by the surface contact midpoint of the first pressure plate and the second pressure plate which are respectively formed with the surface of the cleaning roller and point to the axis and the axis is 60 degrees. When the included angle formed by the surface contact midpoint of the first pressing plate and the second pressing plate, which is formed by the first pressing plate and the second pressing plate and points to the axis, and the axis is smaller than 60 degrees, namely when the total arc length of the first pressing plate and the second pressing plate, which are contacted with the surface of the cleaning roller, only accounts for less than 1/3 degrees of the total arc length of the current section of the whole cleaning roller, and the gap between the arc line of the first pressing plate, which is contacted with the cleaning roller, and the arc line of the second pressing plate, which is contacted with the cleaning roller, is ignored, at this time, the effect of 'embracing' of the cleaning roller by the first pressing plate and the second pressing plate is not obvious jointly, more 'single-side top braking' effects are shown, and the function of 'multi-side embracing' for further stabilizing the operation of the cleaning roller and reducing the jumping radial is lost. The proposal that the included angle formed by the midpoint of the surface contact of the first pressure plate and the second pressure plate and the surface of the cleaning roller, which points to the axis, and the axis is 60-180 degrees is adopted.
The third pressure plate and the first pressure plate respectively form an included angle b with a contact point which is formed on the surface of the cleaning roller and points to the axis and the axis, and the included angle is not less than 120 degrees. When the first pressing plate and the third pressing plate completely 'rightly surround' the cleaning roller, the first pressing plate and the second pressing plate respectively form an included angle of 180 degrees with the surface contact midpoint of the surface of the cleaning roller, which points to the axis, and the axis. In order to cooperate with the cleaning brush 7 to brush off solid pressure and viscous garbage adhered to the surface of the cleaning roller, a gap must be reserved between the contact surface of the second pressing plate and the surface of the cleaning roller and between the contact surface of the third pressing plate and the surface of the cleaning roller to allow the cleaning brush 7 to brush the surface of the cleaning roller with the reserved gap, the gap surface of the cleaning roller accounts for about 1/6 of the surface of the whole cleaning roller, the contact surface of the third pressing plate and the surface of the cleaning roller accounts for about 1/6 of the surface of the whole cleaning roller, and an included angle formed by the contact point of the third pressing plate and the first pressing plate, which are respectively formed with the surface of the cleaning roller and point to the axis is not less than 120 degrees.
The vertical line D passing through the axis of the cleaning roller is positioned on the left side of the movable connection point of the water squeezing strip and the first pressing plate (the end of the first pressing plate, far away from the second pressing plate, is the left side, and the end of the first pressing plate, close to the second pressing plate, is the right side), the resultant force of the first pressing plate and the second pressing plate acting on the surface of the cleaning roller is respectively downward left and downward right, the vertical upward force acting on the surface of the cleaning roller on the ground when the cleaner operates is combined, and the possible leftward upward force acting on the surface of the cleaning roller by the third pressing plate.
In the scheme, the new stress points pointing to the axis by the contact points are added, the included angle formed by the pointing axes between the new stress points is 60-180 degrees, the stress points are not less than 3, so that the resultant force formed by the pointing axes of the stress points tends to zero, the radial uneven stress of the cleaning roller is favorably reduced, and the radial vibration of the cleaning roller and the noise generated by the radial vibration are favorably reduced.
The cleaning roller is slightly in interference fit by adopting large-area elastic rubber before and after the first pressing plate and before and after the second pressing plate, the arc-shaped supporting ribs which are spaced and arranged on the whole garbage channel formed by the third pressing plate and the surface of the cleaning roller corresponding to the third pressing plate in the axial direction also generate slight interference fit for the cleaning roller, so that the cleaning roller is provided with an arc surface corresponding to the first pressing plate on the cleaning roller, an arc surface corresponding to the second pressing plate on the cleaning roller and a plurality of spaced supporting lines formed by the third pressing plate on the cleaning roller, and finally all the forces for supporting the cleaning roller point to the axis, the resultant force of the forces tends to zero, the radial uneven stress of the cleaning roller in the radial direction is favorably reduced, and the radial vibration of the cleaning roller and the noise generated by the radial vibration are favorably reduced. Simultaneously, the whole cambered surface that first clamp plate corresponds on clean cylinder, the whole cambered surface that the second clamp plate corresponds on clean cylinder, because always contact with clean cylinder interference fit, can reduce clean cylinder from the free state to the compression state, from the noise that produces to the deformation in-process of free state, the arc guide face that third clamp plate and clean cylinder correspond simultaneously is owing to only having set up many arc shape brace rods, still can form rubbish guide way between the arc shape brace rod, still kept the third clamp plate and also produced sufficient support to clean cylinder simultaneously for the permeability of clean cylinder's guide rubbish passageway.
The second embodiment:
as shown in fig. 4, the embodiment is different from the first embodiment in that, in the present embodiment, the first pressing plate 2 and the wringing strip 4 are detachably connected, and in the present embodiment, the first pressing plate and the wringing strip are mainly connected by a screw, but the connection manner of the first pressing plate and the wringing strip in the present embodiment is not limited, as long as the detachable connection manner in the field can be adopted as an alternative in the present embodiment. In order to make the connection baffle and the wringing strip be connected seamlessly, in this embodiment, the first pressing plate 2 and the wringing strip 4 are connected through bonding, and through the two connection modes, the seamless connection between the first pressing plate 2 and the wringing strip 4 can be realized, and meanwhile, the first pressing plate 2 and the wringing strip 4 have a small height difference or are approximately flush.
Compared with the embodiment, the other difference is that the elastic pressing strip 21 is not structurally designed in the embodiment, but the inside of the first pressing plate 2 can still be designed into a structure of a variable cavity 23 of the first pressing plate, the other end of the first pressing plate 2, which is far away from the water squeezing strip 4, is freely propped against the cleaning roller cover plate 5, or a bulge can be arranged at the end face terminal and propped against the cleaning roller cover plate 5, and when the cleaning roller cover plate 5 is deformed by external force, the bulge can achieve a certain buffering effect by structural design, so that the force between the first pressing plate 2 and the cleaning roller is reduced, and the normal operation of the cleaning roller is ensured.
Similarly, the cleaning roller cover 5 abuts against the protruding portion of the first pressing plate 2, so as to provide a larger movement and deformation space for the first pressing plate 2, and other structures are the same as those in the first embodiment, and will not be described herein.
As the deformation design of this scheme, the other end that crowded water strip 4 was kept away from to first clamp plate 2 freely with clean cylinder apron 5 looks joint (not marked in the figure), when clean cylinder apron 5 received external force to produce deformation, this joint structural design can reach certain buffering effect to reduce the power between first clamp plate 2 and clean cylinder, guarantee clean cylinder's normal work.
The above design can also satisfy: when the cleaner is used, the first pressing plate 2 is in contact with the surface of the cleaning roller extruded by the water extruding strips 4, and in the process of recovering the extruded surface of the cleaning roller to a free state under the action of the elastic material of the cleaning roller, the structure of the first pressing plate variable cavity 23 of the first pressing plate 2 just absorbs the impact of the surface of the cleaning roller on the cleaning roller cover plate 5. Because there is little difference in height or is close to leveling between first clamp plate and the crowded water strip in this embodiment, the process that the cleaning roller surface after the extrusion resumes to free state under the cleaning roller elastic material effect can smooth excessively, "take up" the process of cleaning roller surface to cleaning roller apron 5 impact also can not produce the noise.
Example three:
as shown in fig. 5, the difference between the first embodiment and the second embodiment is that the first pressing plate 2 includes a limiting portion 21, the limiting portion 21 is a convex structure, in the present embodiment, the end surface of the convex structure is arc-shaped, the arc convex end surface of the limiting portion 21 abuts against the cleaning roller cover plate 5, in the present embodiment, preferably, the arc convex end surface of the limiting portion 21 abuts against the middle portion of the cleaning roller cover plate 5, and the first pressing plate 2 is flush and smoothly connected with the end surface of the water squeezing portion (not labeled in the figure) of the water squeezing strip 4.
In order to reach the effect that above-mentioned terminal surface flushed, the one end that first clamp plate 2 and the crowded water portion of crowded water strip 4 are connected is fixed part 22, and the other end is the free end, is certain contained angle between the terminal surface that this free end and clean cylinder surface contact's terminal surface and fixed slot extend, and preferred acute angle in this scheme is corresponding be equipped with a flush end (not marking in the picture) on first clamp plate 2, after fixed part 22 card goes into the fixed slot (not marking in the picture) of the crowded water portion of crowded water strip 4, flush the end just meets with this contained angle to realize the smooth connection of first clamp plate 2 and crowded water strip 3.
When the cleaning appliance is used, the first pressing plate 2 is in contact with the surface of the cleaning roller extruded by the water extruding strips 4, and in the process of recovering the extruded surface of the cleaning roller to a free state under the action of the elastic material of the cleaning roller, the structure of the first pressing plate variable cavity 23 of the first pressing plate 2 just absorbs the impact of the surface of the cleaning roller on the cleaning roller cover plate 5. Because the first pressure plate and the wringing strip in the embodiment have small height difference or are nearly flush, the extruded surface of the cleaning roller can be smoothly transited in the process of recovering to the free state under the action of the elastic material of the cleaning roller, and the process of absorbing the impact of the surface of the cleaning roller on the cover plate 5 of the cleaning roller can not generate noise.
The invention also provides an embodiment of a cleaning appliance.
As shown in fig. 1, 4 and 5, the present invention provides a cleaning device comprising a cleaning head having a housing 8, the cleaning head being provided with the above-mentioned multi-surface contact cleaning roller mechanism.
In the cleaning appliance, a cleaning roller cover plate 5 is arranged on a shell 8, one end of a first pressing plate 2 is connected with or abutted to the cleaning roller cover plate 5 in a clamping mode, the other end of the first pressing plate 2 is detachably connected with a water squeezing strip fixedly arranged on the cleaning roller cover plate 5, a water diversion strip assembly 3 is fixedly connected with the shell 8, a third pressing plate 6 is fixedly connected with the shell 8, and a variable gap is arranged between the first pressing plate and the shell.
The cambered surface corresponding to the first pressure plate of the cleaning roller on the cleaning roller, the cambered surface corresponding to the second pressure plate on the cleaning roller and a plurality of spaced supporting lines formed by the third pressure plate on the cleaning roller are integrated into an annular three-dimensional supporting system, and finally all the forces for supporting the cleaning roller are directed to the axis of the cleaning roller. The multi-surface contact cleaning roller mechanism with the multi-surface encircling type can absorb the impact of the cleaning appliance on the cleaning roller in the actual use process, reduce the radial runout of the cleaning roller, and reduce the vibration feeling felt by a user through a push rod of the cleaning appliance in the use process, thereby improving the user experience.
According to the embodiment of the invention, during the operation of the cleaning appliance, the cleaning roller 1 rotates, garbage is rolled up through the cleaning roller, clean water is conveyed to the surface of the cleaning roller to wash the cleaning roller, the water diversion strip assembly 3 is installed on the upper portion of the shell 8, the water diversion strip assembly 3 is in interference fit with the cleaning roller, sewage squeezed out through the water squeezing strips during high-speed rotation of the cleaning roller and the clean water conveyed to the cleaning roller are mixed together, and a part of the garbage is taken away through water flow. The first pressure plate and the second pressure plate are made of large-area elastic rubber, slight interference fit is conducted on the cleaning roller, arc-shaped support ribs with intervals are formed in the axial direction of the third pressure plate, slight interference fit is also conducted on the cleaning roller, therefore, an arc surface corresponding to the first pressure plate on the cleaning roller, an arc surface corresponding to the second pressure plate on the cleaning roller and a plurality of spaced support lines formed by the third pressure plate on the cleaning roller are arranged relative to the cleaning roller, an annular three-dimensional support system is formed by the three components in a whole, finally, all forces for supporting the cleaning roller point to the axis, the resultant force of the forces tends to zero, uneven radial stress of the cleaning roller is reduced, and radial vibration of the cleaning roller and noise generated by the radial vibration are reduced. The cleaning appliance can be a product such as a dust collector, a floor washing machine or a sweeping robot.
