Description

Cleaner with brush head for reciprocating or rotating motion {CLEANING APPARATUS WITH RECIPROCATING OR ROTATING BRUSH HEAD}

The present invention relates to a hand holding cleaning device having a brush head for reciprocating or rotating motion.

House cleaning is an endless business. Although there are many sponges and brushes specifically designed to clean large open surfaces such as countertops, sinks, or bathtubs, there are few useful means for cleaning difficult gaps, corners, and inaccessible areas throughout the home. Although conventional sponges and brushes can be used to clean corners and inaccessible areas, the construction and large size of such conventional cleaners make access to such areas difficult. The user applies a force with the tip of his finger to push the cleaner into the gap or corner to be cleaned. Such cleaning is tiring and often leads to pinching of hands and / or fingers.

This problem is compounded by the fact that corners and crevices are where dust, mold, soap debris, and other undesirable things grow or become pinched. As such, cleaning such a place requires additional energy and power.

Conventional toothbrushes are often used to clean inaccessible areas. The problem with toothbrushes, however, is that toothbrushes are typically too soft, do not have the desired angle to extend the hard surface to the fullest and aggressively rub because toothbrushes are specifically designed to clean teeth around sensitive gums. Moreover, due to the small handle of the toothbrush, an important scrubbing with the toothbrush again results in hand pinching and fatigue.

Thus, there is a need for an improved cleaning apparatus that can be used for small, inaccessible spaces and that is durable, can be used with full scrubbing and minimal fatigue.

Various embodiments of the invention will be described with reference to the accompanying drawings. The drawings serve only to illustrate exemplary embodiments of the invention and do not limit the scope of the invention.

The present invention relates to a cleaning device having a brush head for reciprocating or rotating motion. The cleaning device is generally designed for home use when cleaning inaccessible and small areas such as cracks, corners, grooves or cracks. For example, the cleaning apparatus is used to clean corners, countertops and around the faucet of the showerhead. It can also be used for materials that need to be rubbed, such as fabrics and carpets. As such, the device can be used to clean any surface for commercial, residential or other applications. However, the cleaning device is not used as a toothbrush.

One embodiment of a cleaning device 4 incorporating features of the present invention is shown in FIGS. In general, the cleaning device 4 comprises a body assembly 5 having a removable head assembly 6. The head assembly 6 includes a head housing 7 having an upper head housing 22 that engages with the lower head housing 24. Each head housing 22, 24 extends between a near end 32 and a corresponding far end 34.

The head assembly 6 further comprises a rotatable brush head 14 having a brush 16 mounted thereon. As will be described in more detail below, the brush head 14 includes an annular conveying plate 122 having a bottom surface 125 opposite the top surface 124. As shown in FIG. 4, a plurality of tufting holes 170 are formed on the bottom surface 125. In one embodiment, the tongue holes 170 are circular and each has a diameter in the range of approximately 1 mm to 4 mm, generally in the range of 2 mm to 3 mm. The tongue hole 170 is arranged in the concentric ring. Optionally, the sulcus 170 may be arranged in an orderly fashion or in other forms.

In the illustrated embodiment, the outer ring 172, the middle ring 174, the inner ring 176 of the sulhol 170 and the central sulhol 178. As shown in FIG. 3, a tuft 180 composed of a plurality of bristle 182 is disposed in each tuft hole 170. The combined tassel 180 forms the brush 16. The bristles 182 may be made from a variety of different materials having different lengths and diameters. By adjusting the physical properties of the bristles 182, the brushes 16 can be formed to have different stiffnesses to better suit different applications. In general, bristles with short lengths and large diameters have high rigidity.

The bristles 182 may be made of various natural or synthetic materials. In one embodiment, the bristles 182 are made of a polymer material such as nylon. In another embodiment, for the purpose of cleaning the barbecue grill, bristles 182 may be made of a metal such as brass, stainless steel, or copper. As shown in FIG. 1, each bristle 182 has an exposed length L that ranges from approximately 0.3 cm to 2.5 cm, typically 1 cm to 2 cm. The brush 16 has a substantially cylindrical configuration with a maximum diameter D in the range of approximately 1 cm to 5 cm, generally 1 cm to 3 cm, more generally 1.5 cm to 2.5 cm. Larger brushes may have a diameter in the range of approximately 3 cm to 5 cm. In alternative embodiments, brush 16 may have any predetermined configuration and any predetermined dimensions, including longer lengths and diameters, to function for a particular purpose.

Since the head assembly 16 is removable from the body assembly 5, a variety of different head assemblies 6 can be made, each having a brush 16 with different configurations and / or properties. For example, the head assembly 6 is formed to have a brush 16 having soft bristles, medium bristles, hard bristles or a combination of them. In one embodiment, the soft bristles are made of a polymeric material having a diameter in the range of approximately 0.15 mm to 0.25 mm, generally in the range of 0.18 mm to 0.23 mm. Medium bristles typically have a diameter in the range of 0.3 mm to 0.48 mm, generally in the range of 0.37 mm to 0.42 mm. Finally, the rigid bristles of the polymer typically have a diameter in the range of 0.48 mm to 0.75 mm, generally in the range of 0.52 mm to 0.58 mm. In comparison, the bristles of toothbrushes have a diameter smaller than 0.15 mm so that the bristles are not hard and do not damage the enamel of the gums or teeth.

In one embodiment having a combination bristle 182, the tuft hole 170 (see FIG. 4) in the outer ring 172, the middle ring 174 and the inner ring 176 is filled with the middle bristle while the central tuft hole. 178 is filled with hard bristles forming a stopping bristle. The bristles in the stop tuft are shorter than the other bristles. During use, the rigidity of the stop liquor helps to limit the collapse of other liquors when the brush is pressed against the surface to be cleaned. This helps to ensure that the tips of the bristles are used mainly to rub, as opposed to the sides. Bristles with different properties can also be defined by relative percentages. For example, in a brush having stop and wash tufts, the bristles of the wash tuft have a diameter that is at least 20% longer or at least 30% longer than the stop tufts and at least 30% or at least 40% smaller than the bristles of the stop tufts. .

Similarly, in one embodiment shown in FIG. 3, the brush 16 comprises a central tassel 8 surrounded by an outer circumference 9. The outer liquor 9 is somewhat longer and softer than the central liquor 9. As such, the light contact by the brush 16 produces a soft scrub by the outer sulphation 9 while the strong biasing of the brush 16 causes the central sulph 9 to engage the surface. It creates a strong rub. In alternative embodiments, all tufts / bristle may be of the same length, diameter or rigidity or any combination of length, diameter and rigidity that may be used.

The body assembly 5 comprises a body housing 12 having a substantially cylindrical configuration. The body housing 12 may have a circle, ellipse or any other desired cross section and is sized to be gripped comfortably in the user's hand. In one embodiment, the body housing 12 has a maximum diameter in the range of approximately 2.5 cm to 4.5 cm. Other dimensions may be used. The body housing 12 includes an upper body housing 18 that engages with the lower body housing 20. Each body housing 18, 20 also extends from the near end 26 to the opposite far end 28. The upper body housing 18 has an opening 21 on which the flexible button 23 is mounted (see FIG. 5). The end cap 30 is removably mounted to the near end 26 of the body housing 12. The button 23 is located on one side of the cleaning device 4 while the brush 16 protrudes from the other side of the cleaning device 4. This configuration allows the user to easily operate the button 23 while using the cleaning device 4. Moreover, with such a configuration, the force used to press the button 23 with something like a user's thumb can be used to press the brush onto the surface to be cleaned.

The head housing 7, body housing 12 and end cap 30 are combined to form a housing 36. The housing 36 has a substantially cylindrical configuration with a length extending between the near end 32 and the end cap 30, typically about 15 cm to 35 cm, generally 20 cm to 30 cm. Other dimensions may be used. In alternative embodiments, the housing 36 may have a variety of different configurations. Although the housing 36 is not completely symmetrical over its entire length, the housing 36 has a central long axis 38 extending substantially therethrough.

As shown in FIG. 5, the body housing 12 partitions the battery compartment 40, the motor compartment 42, and the shaft compartment 43. Partition 44 is formed between compartment 40 and compartment 42, while compartment 46 is formed between compartment 42 and compartment 43. The battery compartment 40 is accessed through an opening 48 formed in the proximal end 26 of the body housing 12. The opening 48 is optionally closed by the end cap 30. The annular sealing ring 50 forms a liquid waterproof configuration between the body housing 12 and the cap 30.

As shown in FIGS. 5 and 6, the cleaning device 10 further includes a motor assembly 58. The motor assembly 58 includes a motor 60 having a near end 62 and a far end 64 opposite and mounted within the motor compartment 42. The drive shaft 66 terminated in the first coupling 68 protrudes into the shaft compartment 43 from the far end 64 of the motor 60. The first coupling 68 terminates at the end face 70. The end face 70 includes a pair of inclined surfaces 72 connected by stepped showrs 74. The annular shaft seal body 76 surrounds the first coupling 68 and forms a liquid waterproof between the first coupling 68 and the body housing 12.

The battery compartment 40 is configured to receive a plurality of batteries. For example, in this embodiment the battery compartment 40 is configured to accommodate four size AA batteries. Different sizes of batteries or numbers of batteries may be used in alternative embodiments. The positive end of the battery 78 biases the first terminal plate 80 that is electrically energized with the motor 60. The negative end of the battery 78 biases the second terminal plate 82 mounted in the end cap 30.

The extended switch 88 has a first end 90 that is electrically energized with the second terminal plate 82 when the end cap 30 is mounted to the body housing 12. The switch 88 is positioned between the extension base 92 extending along the battery compartment 40, the riser 94 extending along the partition 44, and the button 23 and the motor 60. A protruding flexible lever arm 96. When the button 23 is pressed manually, the lever 96 connects to a circuit biased against the motor 60 and thereby activated by the battery 78. Alternately, when the circuit is connected, energy from the battery 78 causes the motor 60 to drive the drive shaft 66 in rotation. When the button 23 is released, the circuit is cut off and the motor 60 is turned off. In alternative embodiments, various switch mechanisms may be used to allow the motor 60 to operate continuously without manually pressing the button 23 continuously. Moreover, battery 78 may be replaced with an electrical cord.

5 and 6, the head assembly 6 may further include a drive shaft 100. As shown in FIG. 8, the drive shaft 100 includes an extension shaft 102 having a near end 104 and an opposing far end 106. The far end 106 terminates at the far end surface 108. The annular flange 109 is radially enclosed from the shaft 102 at the far end 106 and protrudes outward. Bearing or bushing 162 (FIG. 7) is mounted on shaft 102 to bias flange 109. A second coupling 110 having an end face 112 complementary to the end face 70 of the first coupling 68 is mounted to the near end 104 of the shaft 102. That is, the second coupling 110 is configured to engage the first coupling 68 such that the stepped shoulder 74 biases against the other. As a result, rotation of the drive shaft 66 by the motor 60 is transmitted through the couplings 68 and 110 to rotate the shaft 102.

The stem 114 extends from the end face 108 at the far end 107 of the shaft 102. The round head 116 is mounted on the end of the stem 114. In the above described embodiment, the head 116 is spherical or substantially spherical in shape. As detailed below, the shaft 102 has the same axis of rotation and a central long axis 118 in the above embodiment, and the stem 114 has a central long axis 120. The stem 114 is mounted eccentrically on the end face 108 of the shaft 102 such that the central long axis 120 of the stem 114 is offset from the center of the central long axis 118 of the shaft 102. The rotation axis 118 may be the same axis as the rotation axis and the central long axis of the drive shaft 66 and may be the same as the central long axis 38 of the housing 36 (FIG. 1).

Returning to FIG. 5, the brush head 14 includes an annular transport plate 122 having an upper surface 124 as described above. Spindle 126 protrudes from top surface 124. Spindle 126 includes a central axis 128 having an arm 130 protruding from its respective surface. The axis of rotation 127, around which the brush 16 and brush head 14 rotate, extends through the spindle 126. The rotation axis 127 may be a central axis for the brush 16 and the brush head 14. Hub 132 is mounted on spindle 126. As shown in FIG. 9A, the hub 132 has opposing side surfaces 136, 138 extending between the top surface 140 and the opposing bottom surface 142. Hub 132 also includes a front face 144 and an opposing back face 146. The passage 148 extends from the top surface 140 to the bottom surface 142. The side channel 150 extends through the sides 136, 138 adjacent the bottom surface 142 and in communication with the passage 148.

During assembly, the hub 132 is received above the spindle 126 such that the shaft 128 extends through the passage 148 and the arm 130 is received in the side channel 150. Bearing or bushing 151 (FIG. 5) is mounted on shaft 128 on top surface 140 of hub 132. In this configuration, the hub 132 engages the spindle 126 so that rotation of the hub 132 facilitates rotation of the shaft 126 and the rest of the brushhead 14. In alternative embodiments, the hub 132 may be integrally formed with the brushhead 14.

Hub 132 includes a channel 152 formed in front surface 144 and extending to top surface 140. Channel 152 is vertically aligned with passage 148 and bounded by first engagement surface 156, spaced apart second engagement surface 158 and an inner surface 159 extending therebetween. Engagement surfaces 156 and 158 are opposed to each other and are aligned substantially parallel. Locking channels 160 are recessed along the mating surfaces 156 and 158, respectively. Each locking channel 160 is extended and somewhat rounded along its entire length. The distance between the mating surfaces 156, 158 of the hub 132 is smaller than the diameter of the round head 116.

However, as shown in FIGS. 7 and 10, the hub 132 has a head 116 snap-fit between the mating surfaces 156, 158 in the locking channel 160 formed at the mating surfaces 156, 158. It is configured to be elastically captured. In this configuration, the head 116 is elastically biased between the faces 156 and 158. In the alternative embodiment shown in FIG. 9B, the locking channel 160 may be removed such that the mating surfaces 156, 158 are substantially flat. In this embodiment, the head 116 may be designed to fit snugly or loosely between the mating surfaces 156, 158.

Returning to FIG. 5, the head housing 7 is positioned to contact the bearings 151 and 162 by surrounding the drive shaft 100 and the hub 132. A bayonet slot 164 is formed at the far end 28 of the body housing 12 while a bayonet prong 166 protrudes from the near end 32 of the head housing 7. As such, the head assembly 6 is removably fastened to the body assembly 5 using the plugging connection configuration (FIG. 1).

In the assembled configuration, the couplings 68 and 110 are coupled. Therefore, when the button 23 is pressed, the motor 60 is activated so that each of the drive shaft 66 and the drive shaft 100 rotates around the rotation axis or the central long axis. Alternately, because the stem 114 and the round head 116 are mounted eccentrically on the shaft 102, the head 116 rotates in a circle. That is, as the shaft 102 rotates, the head 116 begins to rotate by drawing an enlarged circle to bias and engage the mating surface 158 of the hub 132 so that the brush head 14 and the brush ( 16) causes hub 132 to rotate about axis 128 in a first direction. The length and arch of the locking channel 160 allows free rotation of the head 116 within the locking channel 160.

Once the head 116 is moved as far as possible in one direction, the head 116 then begins to bias against the opposing mating surface 156 and pivots the hub 132 together with the connected brushhead 14 and brush 16. (128) Rotate around in the opposite direction. As such, rapid rotation of the drive shaft 100 with the head 116 causes the hub 132 to reciprocate rapidly with the brush head 14 and brush 16 connected thereto. By firmly securing the head 116 in the locking channel 16, a snug engagement can be formed between the hub 132 and the head 116. This perfect fit optimizes the transfer of movement between the drive rod 100 and the hub 132. That is, a tight fit eliminates the inclination between the hub 132 and the drive rod 100 even if the head 116 begins to wear in the locking channel 160.

Once the cleaning device 10 is driven, the brush 16 can be biased in contact with the cleaning surface. Brush 16 is positioned in an orientation relative housing 36 to optimize comfort and usability. For example, referring to FIG. 6, in one embodiment, the brush 16 may comprise the body assembly 5 or so as to form an internal angle θ in the range of approximately 90 ° to 180 °, typically approximately 110 ° to 140 °. It protrudes with respect to the central long axis of the head assembly 6. Other angles may be used. In other words, the rotation axis 127 of the brush head 14 or brush 16 intersects the rotation axis 38 of the drive shaft or the central long axis 118 of the housing 36 to form the internal angle θ described above. do. By having an angle in the range of approximately 110 ° to 140 °, the user can be more comfortable to position and use while gripping the housing 36.

The present invention can be embodied in other forms without departing from its spirit or basic features. The above embodiment is merely an example and is not limited. For example, the locking channel 160 may not only be recessed in the inner wall 156, 158, but may extend completely through the hub 132. Moreover, the head 16 need not be spherical. In alternative embodiments, the head 16 may be elliptical or may have a variety of other configurations that couple to complementary locking channels.

Another embodiment of a cleaning apparatus 200 incorporating features of the present invention is shown in FIG. Similar components between the cleaning devices 10 and 200 are distinguished by similar reference features. The cleaning apparatus includes a head assembly 202 and a body assembly 2040. Returning to Fig. 12A, the body assembly 204 includes a body housing 206 formed as a tubular member. And a hand portion 208 having a distal end 212 opposite the end 210. The distal end 212 terminates at an end face 214 on which the tapered tubular stem 216 protrudes. Opposing slots 217 are formed along stem 216. Handle portion 208 and stem 216 typically consist of a fairly rigid plastic, such as ABS, soft and elastic plastic, such as TPE or rubber. An overlay 218 is formed over the portion of the handle portion 208. The overcover 218 improves the grip of the cleaning apparatus 200.

The sea housing 206 has an inner surface 220 bounding the chamber 222. Referring to FIG. 12B, the guide 224 is secured in the chamber 222. Guide 224 includes an extended bulkhead 226 having a distal end 230 opposite the near end 228. Sides of the partition 228 are curved so that the battery 78 can be complementarily received on each side. The cantilever latch 232 is formed at an end 238 close to both the top and bottom surfaces of the partition wall 226. Each latch 232 terminates at barbs 234. The spring 236 is positioned between the partition 226 and each latch 232 such that each latch 232 can be selectively compressed toward the partition 226 and resiliently retracts when released. As shown in FIG. 13, a hole 235 is formed through each surface of the handle portion 208 at the near end 210. Coupling portion 238 of top cover 218 is formed over hole 235. Guide 224 is located in chamber 222 such that each latch 232 is aligned with a corresponding hole 235. The user manually presses the flexible coupling 238 of the top cover 218 inward to selectively press the latch 232 inward.

The latch 232 is used to secure the end cap 240 to the near end 210 of the body housing 206. In particular, the end cap 210 has an opposing inner surface 242 with a pair of opposing hooks 244 formed thereon. When the end cap 240 is pushed onto the proximal end 210 of the body housing 206, the barbs 234 of the latch 232 engage with the hook 244 to bring the end cap 240 into the body housing 206. Secure firmly to In order to separate the end cap 240, when the coupling portion 238 is pressed as described above, the latch 232 is bent inward to separate the barbs 234 from the hook 244.

Referring to FIG. 12B, a cup-shaped support 246 is formed at the far end 230 of the partition 226 and used to support the motor 60. The motor 60 rotates the initial shaft 250 which rotates the drive shaft 254 in turn. The drive shaft 254 has a head 255 formed at the near end. Head 255 typically has a non-circular cross section and may be coupled with the coupler described in detail below. In this embodiment, the head 255 includes a flat portion of the drive shaft 254. In alternative embodiments, the head 255 may have many different polygonal or non-circular cross sections.

The conventional gear assembly 252 extends between the initial shaft 250 and the drive shaft 254 so that the torque generated by the drive shaft 254 is in the range of approximately 1.5: 1 to 3.5: 1. The torque generated by 250). Increasing the torque performance of the drive shaft 254 allows the brush 16 to reciprocate or rotate continuously, even if significant bearing force is applied to the brush while rubbing. This is in contrast to conventional powered toothbrushes designed to stop or significantly slow the movement of the brush so that the toothbrush does not damage the gums when excessive force is applied.

There are a variety of mechanisms that can be used to transfer electricity from the battery 78 to the motor 60. In the illustrated embodiment, four batteries 78 may be arranged in parallel. The negative ends of the two batteries 78 behind are biased in contact with the transfer spring 258 and the corresponding spring 256 in energized state. The springs are mounted to a plate 255 fixed to the end cap 240. The transfer spring 258 contacts and biases the terminal 260. The electrical lead 262 extends from the terminal 260 to the motor 60. The positive ends of the two front batteries 78 are biased in contact with the flexible switch 266 and the corresponding terminal 264 in the energized state. The switch 266 is positioned above the motor 60 so that when the switch 266 is biased in contact with the motor 60, the circuit is completed and the motor 60 is operated.

In alternative embodiments, the batteries 78 may be positioned in line rather than in parallel. In this embodiment, the springs 256 are in energized state with each other but the transfer spring 56, the terminal 260 and the lead 262 are removed. In addition, the two terminals 264 are separated from each other. One of the terminals 264 is in an energized state directly with the motor 60 and the other terminal 264 remains connected to the switch 266. Placing the batteries 78 in line increases the voltage to provide a larger power to the motor.

Referring to FIG. 12A, an opening 270 is formed on the top surface of the body housing 206 to communicate with the chamber 222. The opening 270 is aligned in line with the motor 60 and the switch 266. Flexible diaphragm 272 is secured in opening 270. Diaphragm 272 has an upper surface 274 and an opposing bottom surface 276. The protrusion 278 is formed on the upper surface 274. The cover plate 280 has an elongation hole 282 extending therethrough and is fixed on the opening 270 so that the ball 282 is aligned with the protrusion 278. The button 284 is slidably mounted to the cover plate 280 by the hook 286 and the retainer 288.

As shown in FIG. 14A, the button 284 generally includes a cup-shaped body 290 having an inner surface 292 from which the stem 294 protrudes. The button 284 is made of elastically flexible material, which is typically natural or synthetic rubber. Retainer 288 includes a substantially circular frame 296 having an opening 298 extending therethrough. The opening 298 is at least partially bounded by a lip 300. Retainer 288 is comprised of at least a hard material rather than a material of substantially hard material or button 284. Button 284 is secured to retainer 288 such that stem 294 penetrates opening 298. In one embodiment, the button 284 is secured to the retainer 288 by being molded directly onto the retainer 288 at the time of shaping the button 284, i.

Hanger 286 (FIG. 14B) includes a base 302 having an opening 304 extending therethrough. A pair of prongs 306 protrude upward from the top surface of the base 302 on the opposite side of the opening 304. Hanger 286 is used to secure button 284 on cover plate 280. In particular, the buttons 284 and retainers 288 are positioned on the top surface of the cover plate 280 so that the stem 294 is aligned with the opening 282 of the cover plate 280. The rake 306 of the hook 286 is pressed through the opening 282 of the cover plate 280 from its bottom surface so that the rake lip 300 of the retainer 288 by a snap-fit connection method. Meshes with.

In the assembled configuration above, the button 284 may optionally be adjacent to the cover plate 280 between the off position shown in FIG. 14A and the on position shown in FIG. 14C. In the off position, the projection 278 of the diaphragm 272 is located between the stem 294 of the button 284 and the switch 266 and at least partially within the opening 304 of the hook 286. In this position, the switch 266 is spaced apart from the motor 60 so that there is no electrical contact. From the off position, there are two ways for the user to operate the motor 60. In one approach, as shown in FIG. 14B, the user simply presses the center of the button 284 down. In doing so, the stem 294 is pressed down against the projection 278 that alternately pushes the switch 266 down so that the switch 266 contacts the motor 60 and thereby operates the motor 60. Let's go. When the user releases button 284, button 284 bounces back to the off position.

In the second approach, as shown in FIG. 14C, the user manually slides the button 284 along the cover plate 280. In doing so, the base 302 of the hanger 286 rides on the protrusion 278 which pushes the protrusion 278 downward again to bring the switch 266 back into contact with the motor 60 to drive the motor 60. It works. Motor 60 operates until button 284 returns back to the off position. Thus, the button assembly may allow a single, integrated button to operate the motor in two different modes of operation.

Referring to FIG. 12A, the head assembly 202 includes an upper head housing 22 and a lower head housing 24 each having a near end 32 and an opposite far end 34. The head housing 201 delimits a channel 316 extending along a length that is at least partially divided by complementary partitions 317 formed on the housings 22, 24. Coupling ring 312 is secured between housings 22 and 24 at near end 32. Coupling ring 312 has opposing narrowing rakes 318 formed on its inner surface. The head assembly 202 is housed in the slot 217 into which the insertion rake 318 is inserted and close to the end 32 of the head assembly 202 such that the head assembly 202 is rotated relative to the body assembly 204. Removably secured to body assembly 204 by inserting stem 216 of body housing 206 therein.

The head assembly 202 includes a drive shaft 320 having a near end 322 and an opposite end 324. The near end 322 has a coupler 326 fixed thereto. Coupler 326 has a socket 328 formed on its free end and designed to detachably engage head 255 on drive shaft 254 extending from motor 60. In particular, the socket 328 has a configuration complementary to the head 255 such that when the head 255 is received in the socket 328, rotation of the drive shaft 254 causes rotation of the drive shaft 320. Head 255 is removably received in socket 328 when head assembly 202 is removably coupled with body assembly 204 as described above. The enlarged disk 330 is fixed to the far end 324 of the drive shaft 320. In the above embodiment, the disk 330 has a substantially cylindrical configuration that includes a far end face 334 opposite the near end face 332. The far end 324 of the drive shaft 320 is fixed along the center to the near end surface 332. In contrast, the stem 114 and the round head 116 are mounted on the end face 334 at a position radially spaced outward from the axis of rotation of the drive shaft 320. That is, the stem 114 is mounted eccentrically on the end face 334 in the same manner as described above with respect to the cleaning device 4.

Positioning about the enlarged disk 330 about the end of the drive shaft 320 helps to stabilize the drive shaft 320 during rotation of the eccentrically mounted round head 116. However, in alternative embodiments, drive shaft 320 may have the same diameter as disk 330 or disk 330 may be removed and an arm may be formed between drive shaft 330 and stem 114. Other conventional techniques can be used to eccentrically position the round head 116. The cylindrical bushing 336 surrounds the drive shaft 320 toward the far end 324 and is supported in a support 338 formed on the inner surface of the head housing 201.

Like the cleaning device 4, the cleaning device 200 includes a brush head 14. The brush head 14 includes a conveying plate 122 having a bottom surface 125 having a brush 16 composed of bristles formed therein. The plate 122 also has an upper surface 124 with an axis 126 and an arm 130 protruding therefrom. The axis 128 has a rotation axis that projects along and extends through the center from the spindle 126. The tubular bushing 340 is fixed to the upper head housing 22 and encloses the shaft 128 (FIG. 13). Shaft 128 and spindle 126 are received within hub 342 and wear plate 341 is positioned between bushing 340 and spindle 126.

As shown in FIG. 15, the hub 342 has a substantial front surface 346, rear surface 348 and opposing side surfaces 350, 351, each of which extends between an upper surface 352 and an opposing bottom surface 354. Cylindrical base 344. The passage 356 extends through the center of the base 344 from the top surface 352 to the bottom surface 354. Side channel 358 extends through sides 350 and 351 adjacent floor surface 354 to intersect passage 356. The side channel 358 is configured such that when the spindle 126 is received in the passage 356, the arm 130 is received in the side channel 358 so that the hub 342 is locked with the brush head 14. The wear plate 341 also protrudes from its side and has a tab received in the side channel 358 of the hub 342 so that the wear plate 341 is secured to the hub 342. In one embodiment where the bushing 340 is metal and the spindle 126 is plastic, the wear plate 341 prevents the bushing 340 from causing excessive wear on the spindle 126.

Guide 360 protrudes from rear surface 348 of base 344. Guide 360 includes a first side wall 362, a complementary spaced second side wall 364, and a rear wall 366 extending therebetween. Guide 360 borders channel 368 aligned perpendicular to passageway 356. Channel 368 is bounded by first engagement surface 370, spaced apart second engagement surface 372 and inner surface 374 extending therebetween. Engagement surfaces 370 and 372 are opposed to each other and are aligned substantially planar and substantially parallel. The distance between the mating surfaces 370, 372 of the hub 342 is substantially equal to the diameter of the substantially round head 116.

As compared to the embodiment shown in FIG. 10 and as shown in FIG. 13, the round head 116 is located in the channel 368. Since the round head 116 is continuously rotated around the rotation axis of the drive shaft 320 because of the rotation of the drive shaft 254, the round head 116 pushes alternately opposing mating surfaces 370,372 to the hub 342 In addition, the brush head 14 and the brush 16 reciprocate in a rotation pattern around a rotation axis extending through the spindle 126.

Like the cleaning device 4, in the cleaning device 200, the axis of rotation of the drive shaft 320 is typically greater than approximately 95 °, such that the brushhead forms an internal angle θ within the range of approximately 110 ° to 140 °. Intersect with the rotation axis of (14). Since the round head 116 moves in a circular pattern, the round head 116 moves longitudinally along the length of the side walls 362 and the side walls 364. Because of the inclined orientation of the brushhead 14 seen earlier, the round head 116 is far from the axis of rotation of the brushhead 14 when the round head 116 is positioned at the bottom of the sidewall 362 and the sidewall 364. And the rounded head 116 is closer to the axis of rotation of the brushhead 14 when the rounded head 116 is positioned on top of the side walls 362 and 364. Thus, side wall 362 and side wall 364 are wider at the bottom than at the top to ensure that the rounded head 116 remains in the channel 368 during circular motion.

In one embodiment the round head 116 is substantially spherical in shape. This design has many advantages. For example, because of the inclined orientation of the brushhead 14 as seen above, the round head 116 has a mating surface along many different points of the round head, which are spaced longitudinally from near to far and from top to bottom. Contact with (370,372). By making the round head 116 spherical, this ensures a continuous minimum contact between the round head 116 and the mating surfaces 370, 372 to minimize wear.

Moreover, because of tolerances when mounting the brushhead 14, sometimes when the brush 16 is biased against the cleaning surface, the brushhead 14 is somewhat inclined and the far end of the rounded head 116 is connected to the hub 342. There is a tendency to bias against the inner surface 374 (FIG. 15). Contact between the rounded head 116 and the inner surface 374 helps to stabilize and strengthen the brushhead 14. By making the round head 116 spherical, the contact surface between the round head 116 and the inner surface 374 is minimized. In addition, both sidewalls 362 and 364 terminate at the outer edge 376. This outer edge 376 may be biased against the far end surface 334 of the disk 330 to stabilize and strengthen the brushhead 14 when the brushhead 14 is inclined during use.

In the previous embodiment, the brush 16 has a fixed orientation with respect to the body assembly 204. In one embodiment shown in FIG. 16, the cleaning device 386 may be pivoted along an arrow 390 such that the brush 16 selectively adjusts the orientation of the brush 16 relative to the body assembly 204. It can have a head assembly 388, characterized in that it can. Similar elements between the head assembly 202 and the head assembly 388 are distinguished by similar reference features.

The head assembly 388 includes a hinge 396 that pivotally connects the near head housing 392, the far head housing 394, and the housings 392 and 394 together. As shown in FIG. 17, the close housing 392 has a far end 398. An opening 399 is formed at the far end 398 and the drive shaft 320 extends through the far end 398 (FIG. 18A). Hinge 396 includes a pair of round rakes 400a, 400b that project on each side of opening 399. Hinge 396 includes two identical halves, distinguished by subscripts A and B. Since both halves are identical, only one of the halves will be described in detail here.

The annular ring 402A protrudes from the outer circumferential surface of the rake 400A. A pair of opposed notches 404A are formed on the ring 402A.

Hinge 396 also includes a pair of round arms 406A, 406B that protrude from the far end of near head housing 394. Arm 406A has an inner surface 410A and an outer surface 412A. A substantially circular grooved pocket 414A is formed in the inner surface 410A. Pocket 414A has a plurality of rounded notches 416A formed on the circumferential edge of pocket 414A on its opposite side. Each notch 416A is separated by a ridge 417A. Circular groove 408A is formed on the bottom surface of pocket 414A and is configured to receive ring 402A.

Spring 418A is made of an elastically flexible material, such as the metal commonly used in springs. Spring 418A includes a ring body 420A having an outer surface 422A and an inner surface 424A. The pair of round tabs 426A protrude from the outer surface 422A on opposite sides of the ring body 420A. In addition, a pair of rectangular tabs 428A protrude from the inner surface 424A on opposite sides of the ring body 420A.

During assembly, the tab 428A of the spring 418A is received in an opposite notch 404A on the rake 400A so that the spring 418A is secured to the rake 400A. Next, arm 406A is positioned such that spring 418A is received in pocket 414A and ring 402A is received in groove 408A. Tab 426A is received in corresponding notch 416A such that arm 406A is secured relative to rake 400A. When attempting to change the direction of the brush 16, force is applied to the far head assembly 394 along arrow 390. The force causes the spring 418A to rotate in the pocket 414A. In particular, spring 418A deforms as tab 426A passes over ridge 417A and then resiliently bounces as tab 426A passes within adjacent notch 416A. In part, the movement resistance of the remote head assembly 394 is based on the stiffness of the springs 418A, 418B.

As shown in FIGS. 18A and 18B, as a result of the hinge 396, the brushhead 14 may rotate at a 90 ° angle. For example, the angle θ described above can be selectively adjusted from approximately 90 ° to 180 °. As shown in FIGS. 18A and 18B, the internal components of the head assembly 388 are substantially the same as the internal components of the head assembly 202. However, the shape of the hub 342 is that, when the head 116 moves in a circular pattern, independent of the direction of the brushhead 14, the rounded head 116 is held between the sidewall 362 and the sidewall 364. Somewhat changed. As can be seen from FIG. 16, the brush 16 has a larger diameter than the brush 16 described above and some bristles 182 are longer than others. The present invention may include a kit having a single body assembly and a plurality of different head assemblies that may be selectively secured to the body assembly. Each head assembly can have brushes with different physical properties, such as different sizes, configurations, and / or stiffness of the bristles. For example, a brush 16 is shown in FIG. 19 having a conical tip 434 that can better access and rub inside the corner.

In the embodiment described above, the head assembly is designed to rotate in such a way that the brush reciprocates. In an alternative embodiment, the head assembly may be designed such that the brush rotates in a continuous circular manner. For example, head assembly 436 is shown in FIG. 20A. Similar components between the head assembly 436 and the head assembly 388 are distinguished by similar reference features. Head assembly 436 includes a close head housing 392, a far head housing 394 and a hinge 396. The brush head 438 has a first side on which the brush 16 protrudes and an opposing second side on which the spindle 440 protrudes. Spindle 440 is coupled with universal joint 441. Drive shaft 442 is located in close housing 392. The drive shaft 442 has a coupler 326 mounted on its near end and a universal joint 441 mounted on its far end.

As shown in FIG. 21A and FIG. 21B, the universal joint 441 includes a cup 444 and a ball 446. Spindle 440 protrudes from one side of cup 444 and round socket 448 is formed on the opposite side of cup 444. The socket 448 is bounded by the inner surface 450, and a pair of opposed and spaced rounded projections 452 extend from the inner surface 450 adjacent to the inlet of the socket 448. Ball 446 fits into socket 448. It extends and is formed recessed on each opposite surface of the rounded slot 454, ball 446. Slot 454 is configured such that when projection 452 is received in socket 448, protrusion 452 is received in corresponding slot 454. In one embodiment, the slots 454 may be combined to form one long slot. In this assembled configuration, the continuous rotation of the drive shaft 442 rotates the ball 446, and because of the engagement between the protrusion 452 and the slot 454, the rotation of the ball also results in a cup 444, It causes continuous rotation of the spindle 440, the brush head 438 and the brush 16.

Moreover, because the slot 454 is elongated, the ball 446 can rotate in the socket 448 by a protrusion 452 sliding longitudinally within the elongated slot 454. As a result, as shown in FIGS. 20A and 20B, the spindle 440 pivots freely about the drive shaft 442, and as a result of the hinge 396 as described above, the remote head assembly ( 394 allows pivoting about the close head assembly 392.

22 shows an alternative embodiment of the cleaning apparatus 200. In this embodiment, a light source 460, such as an LED, is mounted on the bottom surface of the body assembly 204, facing its far end. The light source 460 is steered to direct light towards the brush 16 to improve the visibility of the wash surface during use. The lead 462 extends from the light source 460 to the motor 60 so that when the motor 60 is operated, the light source 460 is also activated. In alternative embodiments, a second switch may be provided for the light source 460.

23, another alternative embodiment of a cleaning apparatus 200 is shown. In this embodiment, the light source 460 is installed on the bottom surface of the head assembly 202 to direct light towards the brush 16. Again, lead 462 extends between light source 460 and motor 60. However, in this embodiment, the terminal 464 is formed at the connection between the head assembly 202 and the body assembly 204.

The invention can be embodied in other specific forms without departing from its spirit or essential characteristics. The above described embodiment is merely an example and is not limited thereto. The scope of the invention is defined by the appended claims rather than the foregoing description. All modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
