[0002] Floor scrubbers are common mechanical equipment for cleaning floors. For roller brush structures of roller brush floor scrubbers with triangular designs, the industry currently usually uses flat scrapers to prevent the bristles of the roller brush from being scratched.

[0042] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] 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, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] In order to solve the technical problems in the prior art, the utility model is further described in combination with the accompanying drawings and embodiments:

[0045] like Figures 1 to 8As shown, the embodiment of the utility model discloses a floating comb structure, which is applied to cleaning equipment such as a floor scrubber 7, including a fixed seat 1; a swing plate 2, which can be rotatably mounted on the fixed seat 1, and when the roller brush of the floor scrubber 7 rotates forward, the rotation axis of the swing plate 2 moves away from the roller brush; when the roller brush rotates reversely, the rotation axis of the swing plate moves closer to the roller brush; a comb tooth part 3, which can be elastically and telescopically mounted on the swing plate 2, when the roller brush rotates forward, the comb tooth part 3 combs the bristles of the first depth on the roller brush; when the roller brush rotates reversely, the comb tooth part 3 combs the bristles of the second depth on the roller brush.

[0046] It can be understood that no matter the roller brush of the floor scrubber 7 rotates in the reverse direction or in the forward direction, the comb tooth member 3 always contacts the roller brush bristles. The comb tooth member 3 can comb the roller brush bristles and scrape off the dirt on the roller brush bristles when the roller brush rotates in the forward direction or in the reverse direction.

[0047] In addition to being a roller brush for a floor scrubber 7, the roller brush can also be a roller brush on other cleaning equipment. The roller brush rotates to clean dirt. When the bristles of the roller brush collapse or are scratched, the floating comb tooth structure of this embodiment can effectively comb out the bristles of the roller brush.

[0048] It should be noted that the reverse rotation of the roller brush can be clockwise or counterclockwise, and correspondingly, the forward rotation of the roller brush can be counterclockwise or clockwise, which is specifically determined according to the relative positions of the swing plate 2 and the comb tooth member 3 and the roller brush.

[0049] In this embodiment, Figure 5 As shown in the counterclockwise arrow, when the scrubber 7 is in normal use, the roller brush rotates counterclockwise, and the roller brush partially moves upward, and the swing plate 2 and the comb teeth 3 swing upward to scrape away dirt. Figure 6 As shown by the clockwise arrow, when the floor scrubber 7 is self-cleaning, the roller brush reverses clockwise, at which time the roller brush partially moves diagonally downward, and the swing plate 2 and the comb tooth member 3 swing downward to comb the bristles of the roller brush.

[0050] The magnitude relationship between the first depth and the second depth is specifically determined according to whether the self-cleaning mode of the floor scrubber 7 is forward rotation of the roller brush or reverse rotation of the roller brush. In the self-cleaning mode of the floor scrubber 7, the depth of the comb tooth member 3 extending into the roller brush bristles is greater than the depth of the comb tooth member 3 extending into the roller brush bristles in the normal operation mode. In this embodiment, when the roller brush is reversed as the self-cleaning mode of the floor scrubber 7, the first depth is less than the second depth.

[0051] in, Figure 5 The A in the figure indicates the combing depth of the comb teeth 3. Figure 6 The B marked in the figure indicates the length of the roller brush bristles.

[0052] like Figure 6As shown, after the floor scrubber 7 has been used for a certain period of time, the bristles of the roller brush are in a scraped state, and the roller brush rotates in the opposite direction. The rotation axis of the swing plate 2 in this embodiment is designed to move toward the roller brush, that is, the swing plate 2 and the comb teeth 3 thereon in this embodiment are not fixed, but can move forward and rotate. At this time, the comb teeth 3 on the swing plate 2 approach the roller brush, and the combing depth of the comb teeth 3 and the roller brush bristles is initially increased. In addition, the comb teeth 3 are telescopically installed on the swing plate 2, and the swing plate 2 rotates to drive the comb teeth 3 to rotate, and the roller brush rotates in the opposite direction to apply a downward force, thereby driving the comb teeth 3 to extend toward the roller brush. The distance is increased, and the combing depth of the comb teeth 3 and the roller brush bristles is further increased. Under the combined effect of the swing plate 2 rotating and swinging close to the roller brush and the comb teeth 3 extending longer under the reverse action of the roller brush, the abutment depth of the comb teeth 3 and the roller brush bristles is greatly increased.

[0053] like Figure 5 As shown, when the scrubber 7 is not in use for a short period of time, the bristles of the roller brush are not in a scratched state, and when the roller brush rotates forward, the rotation axis of the swing plate 2 moves away from the roller brush, indicating that compared with the reverse state of the roller brush, the swing plate 2 and the comb teeth 3 thereon move and rotate closer to the fixed seat 1, and the combing depth of the comb teeth 3 and the roller brush bristles is reduced compared with the reverse state. Under the support of the bristles, the supporting force of the bristles on the comb teeth 3 makes the comb teeth 3 extend shorter, and the comb teeth 3 extend shorter in the direction away from the fixed seat 1. However, in the forward state, the swinging rotation of the swing plate 2 and the extension and retraction of the comb teeth 3 can still realize the combing of the roller brush bristles, but the combing depth is shallower than that in the reverse state.

[0054] This embodiment uses a floating comb tooth structure that can swing up and down and elastically expand and contract, so that the combing depth of the comb tooth part 3 on the roller brush bristles is kept basically constant within a reasonable range, thereby ensuring that the combing effect of the comb tooth part 3 on the roller brush bristles is not weakened.

[0055] In some embodiments, a rotating portion 11 is provided at both ends of the fixing seat 1, and the end of the swing plate 2 is installed in the rotating portion 11, and the length of the rotating portion is inclined toward the combing plane.

[0056] By providing the rotating part 11, the rotation axis of the swing plate 2 moves closer to the fixed seat 1 when the roller brush rotates forward, and the rotation axis of the swing plate 2 moves closer to the roller brush when the roller brush rotates forward. At the same time, under the action of their own gravity, the swing plate 2 and the comb tooth part 3 rotate closer to the roller brush when reversed.

[0057] In a specific example, the rotating portion 11 can be a strip hole, or a strip groove or a strip recess. The length direction of the strip hole and the strip groove extends toward the axis of the roller brush. Both ends of the fixing seat 1 are provided with strip holes or strip grooves, and correspondingly, the two ends of the swing plate 2 are respectively assembled with the strip holes or strip grooves.

[0058] The end of the swing plate 2 can rotate in the strip hole or strip groove, thereby driving the entire swing plate 2 to rotate. The rotation axis of the swing plate 2 is parallel to the rotation axis of the roller brush. The end of the swing plate 2 can also migrate and retreat along the length direction of the strip hole or strip groove.

[0059] In some embodiments, a rotating shaft 21 is provided at the end of the swing plate 2, and the rotating shaft 21 is rotatably matched with the rotating part 11. A mounting hole is provided on the swing plate 2, and the rotating shaft 21 passes through the mounting hole, and the rotating shaft 21 is rotatably connected with the rotating part 11.

[0060] In a specific example, Figure 5 As shown, a long circular hole is provided on the fixing seat 1, and the long circular hole is arranged obliquely. The long circular hole is communicated with the mounting hole on the swing plate 2, and the rotating shaft 21 is inserted into the long circular hole and the mounting hole in sequence to realize the rotating assembly of the swing plate 2 and the fixing seat 1.

[0061] In addition, a long circular groove is opened on the fixed seat 1, and the long circular groove is set obliquely. The end of the swing plate 2 is directly connected to the rotating shaft 21, and the rotating shaft 21 is inserted into the long circular groove. The length of the swing plate 2 and the length of the fixed seat 1 are used to realize the rotating assembly of the rotating shaft 21 and the long circular groove.

[0062] In some embodiments, the rotating shaft 21 may be selectively disposed on the fixing seat 1 , and the rotating portion 11 may be correspondingly disposed on the swing plate 2 .

[0063] In some embodiments, for the roller brush type scrubber 7 designed in a triangular shape, the combing surface of the comb teeth 3 is not the arc surface of the round roller brush, and the combing surface of the swing plate 2 and the comb teeth 3 relative to each other is a plane formed between the two roller brushes as a straight surface. When the roller brush rotates forward and reverse, in order for the comb teeth 3 to be able to achieve the elastic and retractable combing effect of the bristles, the original position of the swing plate 2 and the comb teeth 3 is designed to be 90° with the straight surface. If the swing plate 2 and the comb teeth 3 do not have the function of rotating and swinging, the comb teeth 3 will be subjected to a force parallel to the straight surface, and will deviate to the side wall of the swing plate 2, and the comb teeth 3 will be stuck and cannot achieve the elastic and retractable function well. In this regard, the swing plate 2 is further assembled and installed on the fixed seat 1.

[0064] Since the original positions of the swing plate 2 and the comb teeth 3 are at 90 degrees to the straight surface formed between the two roller brushes, when the roller brush rotates forward and reverse, the swing plate 2 and the comb teeth 3 swing upward and downward appropriately, and the brush bristles float up and down steadily and are telescopically combed.

[0065] In some embodiments, the rotating portion 11 provided on the fixing seat 1 has its length extending direction arranged at 90 degrees to the plane formed between the two roller brushes.

[0066] In some embodiments, an elastic member 4 is provided between the comb member 3 and the swing plate 2, and the elastic member 4 is used to provide an elastic force to drive the comb member 3 to extend into the first depth and the second depth of the bristles of the roller brush. The elastic member 4 can make the comb member 3 extend toward the roller brush and retract toward the fixing seat 1.

[0067] It should be noted that the elastic member 4 can be a spring, a highly elastic rubber or other elastic member, which is a prior art. The elastic force of the elastic member 4 is set according to the depth of the comb tooth member 3 extending into the bristles of the roller brush and other actual conditions, so as to ensure that the comb tooth member 3 extends into the first depth when the roller brush rotates forward and extends into the second depth when the roller brush rotates reversely.

[0068] In a specific example, a telescopic channel 22 is provided on the swing plate 2, and the elastic member 4 is installed in the telescopic channel 22. The telescopic channel 22 is used to realize the rapid assembly of the elastic member 4 on the one hand, and to ensure the stable deformation of the elastic member 4 and the stable telescopic movement of the comb member 3 on the other hand.

[0069] In some embodiments, at least two rows of comb teeth 3 are provided on the swing plate 2, such as upper comb teeth and lower comb teeth as shown in the figure, and a partition 23 is provided between adjacent comb teeth 3. On the one hand, the partition 23 separates the comb teeth 3, and the elastic expansion and contraction of each row of comb teeth 3 do not interfere with each other, so as to stably comb the bristles. On the other hand, the partition 23 and the swing plate 2 are convenient for installing the elastic member 4, and the expansion and contraction channel 22 for guiding the deformation direction of the elastic member 4 is designed.

[0070] In the specific example, a first arc-shaped mounting groove 231 is provided on one side of the partition 23, and a second arc-shaped mounting groove 232 is correspondingly provided on one side of the swing plate 2. The first arc-shaped mounting groove 231 and the second arc-shaped mounting groove 232 form a telescopic channel 22, and the elastic member 4 is installed in the telescopic channel 22.

[0071] In a specific example, a support position 31 is provided on one end of the comb tooth member 3 , and the support position 31 abuts against one end of the elastic member 4 .

[0072] In some embodiments, the swing plate 2 is provided with a guide pin 5, and correspondingly, the comb tooth member 3 is provided with a guide hole 6, the guide pin 5 is inserted into the guide hole 6, and the length of the guide hole 6 is extended along the extension direction of the comb tooth member 3 or the elastic member 4. Under the elastic force of the elastic member 4, the comb tooth member 3 extends or retracts toward the rolling brush, and correspondingly, the guide hole 6 moves toward the rolling brush or toward the fixing seat 1. Due to the limiting effect of the guide pin 5, the comb tooth member 3 will not be separated from the swing plate 2.

[0073] In some embodiments, the guide pin 5 can also be set on the comb tooth part 3, and a guide hole 6 can be opened on the swing plate 2. Similarly, the length of the guide hole 6 is extended along the telescopic direction of the comb tooth part 3 or the elastic part 4, and the guide pin 5 is movably inserted into the guide hole 6 to assemble and fix the comb tooth part 3 and the swing plate 2.

[0074] In addition, there is no specific restriction on the number of guide pins 5, guide holes 6, and support positions 31, which can be set according to actual conditions.

[0075] In some embodiments, Figures 9 to 12 As shown, in view of the problem that the structure between the fixed seat 1 and the swinging plate 2 is not flat and smooth, dirt is easy to enter the structure between the fixed seat 1 and the swinging plate 2 during the process of the comb tooth part 3 combing the bristles of the roller brush, and the dirt is difficult or impossible to clean after entering, the floating comb tooth structure also includes an anti-fouling structure 8, and the anti-fouling structure 8 is arranged close to one side of the roller brush to prevent the dirt on the roller brush from entering the floating comb tooth structure during the combing process of the comb tooth part 3, thereby achieving an anti-fouling effect.

[0076] Specifically, the anti-fouling structure 8 includes a first anti-fouling component 81, a second anti-fouling component 82 and a third anti-fouling component 83, wherein the first anti-fouling component 81 is arranged between the upper side of the fixed seat 1 and one side of the swing plate 2, the second anti-fouling component 82 is arranged between the lower side of the fixed seat 1 and the other side of the swing plate 2, and the third anti-fouling component 83 is arranged on the side of the swing plate 2 close to the roller brush. The third anti-fouling component 83 is provided with a telescopic opening, which accommodates the extension and retraction action of the comb tooth component 3, and the width of the telescopic opening can be slightly larger than the thickness of the comb tooth component 3.

[0077] In some embodiments, the first anti-fouling member 81 and the second anti-fouling member 82 are made of a material with elastic shrinkage performance, and can be freely extended and retracted as the swing plate 2 swings up and down.

[0078] Preferably, the first anti-fouling member 81 and the second anti-fouling member 82 are made of rubber material, which, on the one hand, does not affect the up and down swinging of the swing plate 2; on the other hand, when dirt is attached to the first anti-fouling member 81 and the second anti-fouling member 82, it is easy to clean, especially when the dirt is accumulated too thickly, it is easy to disassemble and clean, and does not affect the cleaning of the roller brush bristles.

[0079] Furthermore, the third anti-fouling member 83 may also be made of rubber material to facilitate cleaning of attached dirt.

[0080] In addition, the first anti-fouling member 81 , the second anti-fouling member 82 and the third anti-fouling member 83 are extended along the length direction of the roller brush or the swing plate 2 , completely covering the gap space between the fixed seat 1 and the swing plate 2 and the gap space between the comb tooth member 3 and the swing plate 2 .

[0081] More preferably, the first anti-fouling member 81, the second anti-fouling member 82 and the third anti-fouling member 83 are made of elastically stretchable rubber sheets.

[0082] In some embodiments, the first anti-fouling component 81, the second anti-fouling component 82 and the third anti-fouling component 83 may be installed by any one of snap-on installation, screw installation, and adhesive installation, or a combination of any two or more thereof.

[0083] In a specific example, a first limiting groove is provided at the upper end of the fixed seat 1, a first positioning groove is provided on the upper side of the swing plate 2, a first limiting block is provided at one end of the first anti-fouling component 81, and a first positioning block is provided at the other end of the first anti-fouling component 81. The first limiting block is embedded in the first limiting groove, and the first positioning block is embedded in the first positioning groove.

[0084] In another specific example, a second limiting groove is opened at the lower end of the fixed seat 1, a second positioning groove is opened at the lower side of the swing plate 2, a second limiting block is provided at one end of the second anti-fouling member 82, and a second positioning block is provided at the other end of the second anti-fouling member 82. The second limiting block is embedded in the second limiting groove, and the second positioning block is embedded in the second positioning groove.

[0085] In another specific example, the outer periphery protrusion of the third anti-fouling member 83 extends to form an undercut portion, and the undercut portion is engaged with the outer periphery of the swing plate 2 for installation.

[0086] In yet another specific example, the third anti-fouling member 83 is mounted on the swing plate 2 by adhesive bonding.

[0087] In some embodiments, Fig.11 As shown, a first receiving space 801 is formed between the upper side of the fixed seat 1 and the upper side of the swing plate 2. During the forward rotation of the roller brush and the upward swing of the swing plate 2, the first anti-fouling member 81 is shrunk in the first receiving space 801. Preferably, a supporting rib can be provided in the middle portion of the first anti-fouling member 81, so that during the forward rotation of the roller brush, the middle portion of the first anti-fouling member 81 does not protrude too much toward the roller brush, but bends and shrinks away from the direction of the roller brush to avoid the first anti-fouling member 81 protruding too long and possibly affecting the movement of the roller brush.

[0088] In some embodiments, Fig.12 As shown, a second storage space 802 is formed between the lower side of the fixed seat 1 and the lower side of the swing plate 2. During the reversal of the roller brush and the downward swing of the swing plate 2, the second anti-fouling member 82 is shrunk in the second storage space 802. Preferably, a support rib may also be provided in the middle of the second anti-fouling member 82 so that during the reversal of the roller brush, the middle of the second anti-fouling member 82 does not protrude too much in the direction of the roller brush, but is bent and contracted away from the direction of the roller brush to avoid the second anti-fouling member 82 protruding too long and possibly affecting the action of the roller brush.

[0089] This embodiment also provides a cleaning device, including the above-mentioned floating comb tooth structure.

[0090] The main functions of this utility model:

[0091] The utility model installs a swing plate on a fixed seat and designs that when the roller brush rotates forward, the rotation axis of the swing plate can move close to the fixed seat and rotate under the drive of the roller brush, and when the roller brush rotates reversely, the rotation axis of the swing plate can move close to the roller brush and rotate under the drive of the roller brush. In this way, the swing plate is not fixed and can swing up and down under the drive of the roller brush.

[0092] At the same time, an elastically retractable comb tooth part is installed on the swing plate, so that when the roller brush rotates forward, the comb tooth part can comb the bristles of the roller brush at a first depth, and when the roller brush rotates reversely, the comb tooth part can comb the bristles of the roller brush at a second depth. This solves the problems of bristle collapse and scratching after the floor scrubber has worked for a certain period of time, and can realize the combing of roller brush bristles at different depths, thereby improving the combing effect.
