[0022] Specific embodiment:

[0023] A scrubbing machine brush disc, characterized in that the brush disc 1 installed on the bottom of the scrubber is provided in a conventional manner, that is, a brush disc (also called a disc brush) installed on an existing scrubber or a single wiper. ), the concentric circles set by the brush 1 or Randomly disposed bristles 3, and at least one radially arranged curved brush piece 4 or brush strip, the brush piece 4 or the brush strip can be continuously or intermittently, the suction plate 6 has a suction port 6 in the middle of the brush plate, the brush disk is rotated, and the bristles 3 are substantially The concentric pattern rotates, the brush sheet 4, and the brush strip rotates centripetally. The suction port 6 has a shape of a circle or a square shape at the center of the brush disc 1, or is adjacent to the center of the brush disc 1, and has a ring shape or a belt shape.

[0024] That is, the centripetal rotating brush 4 or the brush strip described in the specification of the patent CN102908102 is added to the brush of the conventional washing machine and the single wiping machine, compared with the brush disc described in the specification of CN102908102, the bristles 3 It is a distribution pattern of traditional concentric circles (such as scrubbers, bristles on a single wiper). This invention cannot be simply considered to be a combination of two types of brush discs, since both types of brush discs are designed for the same purpose and can be used separately, and there is no need to combine the inventions, and the present invention The brush disc has a centripetal rotating brush 4 or a brush strip which is not on the conventional brush disc, and there is no bristles that rotate centripetally on the brush disc described in the specification of CN102908102, and there is a suction port 6 in the center of the brush disc; CN102908102 also has no intentional description. The description or revelation of water leakage to reuse and improve water utilization, the oppositely rotating bristles, brush 4 or brush strips all serve to push water quickly toward the mouthpiece 6.

[0025] Of course, the bristles 3 on the brush disc 1 are not in a concentric manner, and may be randomly set (as long as it is not a centripetal rotation), the random setting may be a uniform (or symmetric) distribution, or may be uneven. Distribution, but the brush is in the planting, concentric circles are traditional craftsmanship.

[0026] The brush disc described in the present invention may also be a combination of two brush discs modified: one is a brush disc with a brush 3 for a conventional scrubber, and the other is a centripetal belt with a brush 4 or a brush strip. Rotating the coverless brush plate, the two brush plates are combined into one, the concentric round brush brush plate is on, the centripetal rotating brush brush brush plate is on the bottom, the centripetal rotating brush brush brush plate disk A reinforcing rib 10 is provided between the spoke 2 and the spoke 2. The spokes 2 for holding the brush or brush strip are disposed between the plurality of concentric ribs 10, as shown in Fig. 3, which may be provided by welding (metal parts) or one-shot (plastic parts) or riveting, or using iron sheets. The hoop and the screw are fixed, and the two brush plates are superposed together by a snap or iron 29 plus a screw.

[0027] The concentric circular brush disk can also be placed underneath, and a curved through-hole groove 24 (through the brush disk) is disposed on the brush cover of the brush brush disk, and the above-mentioned centripetally rotating brush brush strip transmits the curve on the brush disk. The shaped slot 24 is in contact with the ground.

[0028] It is not necessary to provide (grinding) the bristles in the place where the concentric circular brushing discs are provided with curved brush pieces or brush strips, or the bristles of the portions where the brush sheets or brush strips are provided are cut off on the conventional brush discs.

[0029] The brush disk 1 rotates (one-way rotation) 吋, the bristles 3 rotate in a concentric manner, and the brush sheets 4 and the brush strips are concentrically rotated. Turn. The bristles 3 and the brush sheets 4 and the brush strips are intermittently arranged, and the brush sheets 4 or the brush strips can also be continuously disposed, but the rotational enthalpy resistance of the intermittent arrangement is smaller, and for the brush sheet 4, the extension from the brush sheet 4 to the suction port 6 After scraping (collecting) a part of the water and letting it leak out, the leaked water is repeatedly used by the bristles 3, and then scraped by the brush 4 toward the suction port 6, which can better provide water utilization. The intermittent setting may be that the brush piece 4 and the brush strip are arranged in a section, as shown in Fig. 1, a brush piece or a brush strip in each through hole, and a plurality of brush pieces or brush strips are arranged, and each brush piece or brush strip is also located at the ground. Cut at least one section, or it can be a whole brush (or brush strip), cut off a section of the ground, and cut off the entire brush (or brush strip) in multiple places (at least one place), as shown in Figure 3.

[0030] The brush tray 1 can be provided in plurality under the washing machine. For example, two, three, four, the plurality of brush discs 1 can share a rotating system, and a plurality of suction ports 6 lead to a garbage suction passage 5. Each of the brush discs 1 can be driven by a common method such as turning or gears, or a brush disc 1 can be driven, and the outer edges of each of the brush disc covers have gears, and the gears of the outer edges of the respective brush disc covers are engaged with each other (three brush discs) The rotation direction of the brush disc 1 in which the outer edges of the brush cover are engaged with each other is reversed, so that the bending direction of the spokes 2 is also reversed.

[0031] The rotation speed of the brush plate 1 should not be too fast, otherwise the friction force will be large, and the ground or the brush itself (including the bristles 3, the brush 4, the brush strip) may be damaged, generally similar to the speed of the existing washing machine.

[0032] The brush sheet 4 and the brush strip can be mounted by inserting on the spoke 2 by means of a pin, or can be fixed by glue or Velcro (hook and loop), and can be fixed like a wiper or a mop on a car. The brush 4 can be clamped to a curved disk by means of a strong clip (or long clip) or a plate clamp (or a wire and a wire buckle used in an old free clip) as in the existing folder clip. On the spoke, the spoke 2 may be a plastic piece integrally formed with the brush disk or attached to the brush disk by screws, or the metal piece may be fixed by screws, but the folder of the paper is flat, and the clip of the brush 4 is The curved vertical clamping of the brush 4 (generally a rubber sheet) is clamped by the clip because the removal of the brush 4 (replacement or height adjustment) is more flexible and convenient, and the brush 4 can also be fixed by screws or snaps. Figure 1 is a further improvement of the existing brush disk: set on the brush plate (post-processing or one-shot) curved shape for clamping (clamping and supporting) the bump 27 of the brush (equivalent to the spoke) The protrusion 27 has a groove 24 in the middle, and the groove 24 is provided with a brush piece 4, the groove 24 can pass through the brush plate, and a buckle or a cover is arranged on the top of the brush plate to press the top end of the brush piece, and can be inserted or pulled from the top of the brush plate Out of the brush 4, the cover can also be fixed by screws (threads) or snaps or slots, all covering all or part of the groove, a plurality of spacers 26 slightly smaller than the grooves can be provided, through the brush and the buckle or The height of the worn brush sheet 4 to expose the underside of the recess 24 (between the ground) is adjusted by adding a layer to the multi-layer spacer 26 between the covers. Or concave The groove 24 is not penetrated, and the brush piece 4 is inserted or pulled out from the bottom of the brush plate, and a buckle 25 (see Fig. 1, 2a) or a pin or a screw is arranged on the side of the convex groove 4, which can be laterally located at the corresponding position of the brush piece 4. a plurality of holes are longitudinally arranged for adjusting the height of the brush and adjusting the height in the vertical direction. A plurality of spacers 26 may be disposed in the groove 24 to adjust the height of the brush in the vertical direction, and the purpose of adjusting the height of the brush 4 is In order to effectively improve the utilization rate of the brush 4 on the brush disc 1 after wear.

[0033] The brush tray also has a water leakage hole 28 for dripping water under the brush tray.

[0034] The brush sheet 4 may be vertically or obliquely provided with leather, plastic or rubber for scraping the dirt or liquid attached to the surface (for example, thermoplastic elastomer rubber commonly known as "beef tendon"), such as existing scrubbing. The water-absorbent strip of the machine, which can be used as a strip or roller material made of rubber, sponge, foam (plastic), chemical fiber, felt, paper towel, towel, cloth strip, leather, etc., can be used for water absorption or scraping or cleaning. Brush 3, brush 4, brush strip can also be made of other materials (can be used for sweeping or mopping). It should not cause damage to the ground, and wear and friction are small. Brush 4 and brush strip should be easy to replace. The edges of the bristles 3, the brush 4, and the brush strips may be slightly extended (extending the spokes) to expose the bottom of the body of the scrubber to ensure contact with walls or obstacles, and to have a slight flaw in the wall or obstacles. . As described in the specification of CN102908102, the brush strip is generally thicker than the brush sheet 4. For convenience, Figures 1 to 3 do not show the brush strip, but the brush strip can be arranged at the place where the brush sheet 4 is arranged, or the curved disc spoke can be added. 2 It is used to set another brush strip. The setting method can also be embedded or clamped like the brush 4, or other mopping or mopping strips.

[0035] The brush disc 1 and the brush disc drive shaft 11 can be connected in a conventional manner (in the manner of a conventional scrubber or a single wiper), but it is necessary to provide a suction passage 5 in a conventional drive shaft, if the center of the original drive shaft Since the motor (and the planetary gear member) is to be mounted, the motor needs to be moved to the side to drive the brush drive shaft 11 because the suction passage 5 is to be installed. The suction passage 5 can be fixed and not rotated, and a bearing 21 is arranged between the drive shaft 11 and the suction passage 5, as shown in Fig. 4 (a, b, c), and the related description refers to CN104127158, and the suction passage 5 can also rotate synchronously with the drive shaft. A bearing 21 is arranged between the drive shaft and the waste bin (container) or the sewage tank. The advantage of the rotation is that on the one hand, the air flow can form a vortex in the suction passage 5 (similar to a tornado), and the garbage and water droplets can be centrifuged to the periphery. On the other hand, the brush disc rotates synchronously with the suction passage 5, and the long hair is not wrapped between the rotating brush disc 1 and the suction passage 5, as shown in Figs. 5, 6, and 7 (Figs. 5 and 6 are wet and dry). With the cleaning device, refer to CN104622386 for other parts in the figure, wherein Figure 5a is dry suction (vacuum suction method). In this way, no filter 8 is needed at the suction port 6; Figure 6 Filter frame 9 at the suction port Curved Trumpet-shaped, close to the ground, can block large particles of garbage outside the filter frame 9 , this filter frame can be screwed under the suction channel.

[0036] The brush disc 1 and the drive shaft 11 or the scrubber chassis may be provided with a spring to keep the ground in contact with the brush disc 1, and the crucible may not be too tight to cause the brush 3, the brush 4 or the brush strip on the brush disc 1 to be easily Wear and friction, the suction port 6 can be at the center of the brush plate 1, the drive shaft 11 is tubular at the periphery of the suction port 6; or the drive shaft 11 is at the center of the brush disk 1, and the suction port 6 is a ring at the periphery of the drive shaft 11 (with a connection brush inside) The rib of the disk and the drive shaft) or the belt shape, or the drive shaft 11 is also tubular, the suction port 6 is a ring or a belt at the periphery of the drive shaft 11, and the hollow portion of the center of the brush disk 1 (in the inner side of the drive shaft 11) can be installed with a washing machine Drive wheel or support wheel or sensor.

[0037] The brush disc 1 and the drive shaft 11 can also be installed by means of a brush holder 7 commonly used in current scrubbers or single wipers.

[0038] The suction passage 5 of the present invention is generally a straight pipe that is vertically upward, and may of course be inclined or bent (generally not more than 90 degrees), and the airflow in a straight upward direction is more efficient, and the inclined or bent can be centrifuged. The impeller 39 is vertically (corresponding to the chassis) or eccentrically arranged for a more flexible structure. The suction passage 5 can also be thinned down or down.

[0039] In order to prevent the large group of garbage from clogging the mouthpiece 6, a blocking frame can be arranged around the mouthpiece 6, and the blocking frame has a grid to shield the sharp objects such as large group of garbage and stones.

[0040] In order to prevent the hair from being entangled on the centrifugal impeller 39, it is difficult to clean, and a small mesh of the eye may be provided, and the small particle garbage and most of the hair are blocked in the vicinity of the suction port 6 for cleaning, and the lower end of the mesh faces the suction port 6 The part has an acute angle (small wind resistance), not necessarily located at the mouthpiece 6, or in the suction channel 5, such as near the mouthpiece 6, to facilitate cleaning of particles and hair trapped under the grid. It is an inverted bucket, the mesh is located at the bottom of the bucket, and the outer frame of the bucket is slightly smaller than the suction passage 5, as shown in Fig. 4a, in the manner of embedding (or fitting) the suction passage 5, which is disposed above the inside of the suction opening 6, such as filtering tea leaves in the teacup The filter clasp or threaded on the teacup (inverted).

[0041] Further improvement: a pair of concave slits 40 having a circular arc shape at the top end of the suction passage 5 near the suction port 6, as shown in FIG. 8, inserted into the roller curler 12, through the wall of the suction passage 5 The bevel gear 13 is disposed on at least one side of the outer ends of the two sides of the elongated curler 12 of the concave mouth, as shown in FIG. 4b, FIG. 5, and the center (inner ring) position of the brush disk 1 or the disk drive shaft 11 is inclined The tapered teeth of the inner edge are engaged. If only one end of the roller has a gear, the other end of the roller can be jammed and passively rotated, as shown in Fig. 9 (a, b, c). In Fig. 9a, both ends have tapered gears 13 Figure 9b—the end has a gear 13 and the other end has a bearing 15 at the contact wall of the suction passage 5, and one end of Figure 9c There are bearings 15 at the two places where the gear and the suction passage 5 are in contact with the wall. In order to prevent the tapered gear 13 of the roller curler from being subjected to the force and then moving to the other side, the step 16 may be provided at the contact of the roller with the bearing; A cylindrical gear 14 is disposed at at least one end of the roller, as shown in Fig. 4c, the lower edge of the inner ring of the brush or the lower end of the brush drive shaft 11 is engaged with the cylindrical gear 14 of the two ends or one end of the roller, as shown in Fig. 9 (d , e, f), in Figure 9d, the roller has gears 14 at both ends, a bearing 15 on the side where the suction passage 5 is in contact with the pipe wall, and no bearing on the other side, and the roller outside the pipe wall of the suction passage 5 is thick, the pipe wall The inner roller is thin (the roller outside the tube wall is thin, and the roller inside the tube wall is thick). In Fig. 9e, the roller side is convex on both sides of the tube wall, and the roller is stuck and does not slide. The roller in Fig. 9f The depression at the contact of the pipe wall is caught by the pipe wall. The suction port 6 of the suction passage 5 has a nut 16 or a cuff 17 outside the suction passage 5 (of course, also in the suction passage 5), and the roller curler is supported below. If the nut 16 is screwed on, it is preferable to A concave block 40 is formed on the inner and outer sides of the tube wall or the tube wall is embedded with a circular-shaped concave block 18 for inhaling the lower half of the roller curler 12 (or the bearing 15). The gap at the concave mouth of the channel 5 is blocked (no air leakage), as shown in Fig. 8a; if it is the collar 17 pushed up vertically, the bracket is not needed, and a circular recess is placed on the sleeve. (Snap) The lower half of the roller curler 12 (or bearing 15) can be used, as shown in Fig. 8b, in order to prevent the cuff 17 from being worn after repeated use, a buckle can be provided, or a nut can be screwed down. withstand. If the nut 15 is used to hold the bearing 15 or the ferrule 17, the spring washer can be used to prevent the nut from loosening on the nut. The nut or the ferrule can also be like a bottle cap. The filter screen 8 is provided at the bottom of the bottle cap (usually using lead wire or Stainless steel wire, which is durable and rust-proof, has a large filter screen for filtering dust inside the vacuum cleaner. It is also a blocking frame (filter frame). Bearing 15 is preferably made of rust-proof material.

[0042] The nut 16 or the cuff 17 described above may also replace a portion of the wall of the suction passage 5 below the roll-shaped curler 12.

[0043] The concave slits 40 on the wall of the suction passage 5 are not necessarily a pair, and one may be, that is, the curler 12 only penetrates the wall of the suction passage 5 on one side, and the curler 12 does not have a gear (13) Or the other side of 14) is suspended in the suction passage 5.

[0044] The female recess 40 may also only be a hole in the wall of the suction passage 5, and one side or both sides (opposite side) of the tube wall are present, and the curler 12 is pulled out or fitted from the outside of the suction passage 5. The suction duct 5 is required to have a slightly thicker wall (at least one side) at the round hole, and the curler 12 is provided with a bearing 15 (at least one side) through the pipe wall, and a plastic outer casing can be added outside the bearing, and the outer side of the outer casing is threaded. , with the curler 12, the bearing 15 is screwed on the pipe wall, or screwed out to remove; or the jacket itself is tapered (wedge, 锲) shape, through the stuck and pulled out Install or remove the method; or install the slider and the buckle on the outer wall of the suction passage 5, and slide the slider to catch or loosen the bearing 15 of the jacket of the curler 12.

[0045] The brush disk 1 rotates to drive the curler 12 to rotate, and the longer hair that may enter the impeller 39 through the suction passage 5 is wound on the curler 12, and the curler 12 is directly cut off irregularly (roller type) The hair on the surface of the curler has a concave or concave surface, or the curler 12 is removed to clean the hair. The roll shaft of the curler 12 is not necessarily cylindrical, but may also be a diamond (or square). Columns, columns can also be provided with protruding plastic or metal (such as stainless steel) or ceramics, such as the edge of the hair can be wound on the roller to cut the hair. The ends of the roller or the teeth along the inside of the brush disc may have teeth in one turn, or partially toothed, allowing the curler 12 to rotate straight, or stop and stop. The role of the curler is that there is a roll-shaped curler in the suction passage 5 near the suction opening 6 (and on both sides outside the suction passage 5) when the brush tray 1 is rotated or not, regardless of whether the suction passage 5 is rotated or not. 12 The shaft around the roller rotates, and if the suction passage 5 rotates with the brush tray 1, the self-rotating of the roller-shaped curler 12 is also rotated in the horizontal direction in synchronization with the suction passage 5.

[0046] If the suction passage 5 is also rotated together with the brush tray 1, it is also possible to provide only the screen frame 9 (or the stopper frame) at the bottom of the suction port 6, without the crimper 12.

[0047] If the suction passage 5 is rotated in synchronization with the brush disc 1, one or more spiral vanes 19 may be provided from the bottom of the suction passage 5, as shown in FIG. 7, a plurality of (multilayer) are provided on the suction passage 5. Window 20, outside the window 20 (around the suction passage 5), a garbage collection box is provided, and the heavier granular waste (or water droplets) is thrown out of the suction passage 5 by the centrifugal force and enters the garbage collection box. The garbage collection box is an integral one of the center pupils, or two flaps (or multiple flaps, with an extractable bridge flap (saddle shape) between each flap to prevent rubbish or water from entering the gap between the two flaps) The dumping is removed and the bridge flap 38 can also be mounted at the window to prevent debris or water from entering the gap between the suction passage and the drive shaft or the sewage container or waste container.

[0048] For the current washing machine, only the bristles 3 and the brush 4 are needed on the brush plate, and the brush 4 is generally a water absorbing rubber sheet (that is, the water absorbing rubber strip installed on the squeegee used in the current washing machine). ).伹 For floor-floor mopping machines for home use, it is best to have a brush strip to facilitate the suction of the squeegee 3 and the squeegee 4 scraped into the gap in the floor.

[0049] The brushing disc of the present invention can be used to change the single wiping machine on the market to a washing machine, which can expand the sewage collecting function that the original single wiping machine does not have, so that the washing machine can be more compact like a single wiping machine. It can be used in a narrow space (compared to dining places), and does not need to be rotated like the current compact floor scrubber. Such as Figure 10, modified 吋, it is best to add an adjustable height support wheel 22 on the front end of the existing single wiper, generally a universal wheel, adjust the height of the support wheel bracket off the ground by rotating a screw 23, adjust this The reason for the height is to maintain a certain pressure contact between the brush and the ground in the event of wear of the brush disc. Of course, the adjustment height is not necessarily limited to the support force (universal wheel) side, but also on the side of the drive wheel, or between the drive shaft of the scrubber and the brush disc by the nut and spring, the existing scrubber The brush tray height adjustment device is available.

[0050] The brush tray of the present invention can also be used for ordinary vacuum cleaners, washing machines, waxing machines, and the like, and can be used for cleaning walls and glass (sands) in addition to cleaning the floor.
