Description

(Related application)
This application consists of a US patent application number [Attorney Case No. JNOZ 2 00002], the name “HAND-HELD, BATTERY POWERED CLEANING TOOL” (filed October 8, 2002), and the same application. No. [Attorney Case No. JNOZ 2 00003], the name “HAND-HELD, BATTERY POWERED CLEANING TOOL” (filed on Oct. 8, 2002). Both applications are incorporated herein by reference.

  The present invention relates to a cleaning tool technology. The present invention is described in terms of household cleaning tools, such as kitchen or bathroom cleaning tools. However, the present invention is applicable to other cleaning, polishing, polishing, or similar applications.

  Known battery powered cleaning tools have at least one of the following three drawbacks. They require non-standard power sources or batteries that are not readily available, include slide switches that are not intrinsically instantaneous, and / or a cleaning head or a relatively narrow portion of the cleaning attachment or Apply torque and thus stress to the brush.

  For example, US Pat. No. 5,870,790 (Root et al.) Discloses several battery powered polishers. Each disclosed polisher includes a single rechargeable battery. Root does not disclose the size or type of battery. However, the relative size and shape of the batteries shown in the figure, and the expected power requirements of the polisher, indicate that the battery considered by Root is of a type that is not readily available to the general public. .

  Rechargeable batteries have a limited lifetime. Moreover, it is known that rechargeable batteries have favorable usage conditions and protection conditions. For example, the useful life of some rechargeable batteries is shortened if the battery is not fully discharged before charging. Many users of battery powered cleaning tools are either unaware of the rechargeable battery protection regime or dislike taking the required attention to it. Thus, replacement difficulties due to the unusual nature of Root rechargeable batteries can result in a shortened useful life of the entire instrument.

  The Root polisher also includes a switch. Root does not disclose the type of switch. However, the switch disclosed in Root appears to be push-on / push-off or slide-type. For example, one switch is placed at the rear end of the polishing tool. In that position, the switch cannot be reasonably held in the on position during use of the tool. Non-instantaneous switches can be a problem in cleaning tools, as some distracted users may forget to stop the tool before placing it on a countertop, for example. For example, the user may be distracted by the phone or child and place the cleaning tool on the countertop with the cleaning head rotating. In that case, the cleaning tool may run across the countertop and knock the glass and dishes onto the floor. On the other hand, if an instantaneous switch is incorporated in the cleaning tool, the cleaning head stops moving as soon as the tool is released. Further, including a momentary activation switch in the cleaning tool helps save energy. For example, by using a momentary switch, the tool is de-energized whenever the cleaning operation is paused or whenever the user is not intentionally operating the machine. Therefore, the battery life is extended.

  Finally, Root discloses several cleaning heads. The cleaning head includes a relatively thin hexagonal male member received in the hexagonal socket of the cleaning tool body. Thus, when the tool is actuated, torque is applied with a very short moment arm to the edge and surface of the hexagonal male member. Since the torque is applied with a relatively short moment arm, the cleaning head in operation as disclosed by Root is subject to excessive mechanical stress, which is premature aging, and ultimately fatigue and brushing. It can lead to damage.

  Similarly, US Pat. No. 6,295,681 B1 (Dolah) discloses a rotating brush cleaning device, which appears to be a rechargeable battery enclosed in a power case and a slide switch. Includes a switch of the type not disclosed, and a plurality of cleaning heads. Drolah suggests that replaceable batteries can be used, but does not provide enough replaceable battery arrangements to provide the necessary power, and an ergonomic form factor Nor does it present a brush design that is adaptable to replaceable batteries while maintaining an attractive design. The brush disclosed by Dollah includes a base portion that is used to connect the brush to the body of the cleaning implement. The base portion includes an L-shaped groove for receiving the pin of the cleaning implement. Although none of the references are given dimensions, the basic part of Dollah appears to be larger in diameter than the male part of the Root. Thus, the Dorah can transmit torque to the brush with a slightly larger moment arm. However, the Dorah brush includes a relatively thin and long intermediate shaft. A relatively thin and long intermediate shaft can experience excessive stress concentrations, which can lead to premature failure.

  A third reference, US Pat. No. 4,137,588 (Sandt et al.), Discloses a portable cleaning instrument. Similar to Root and Dorah, Sandt discloses a cleaning implement having a switch type not disclosed. However, the switch appears to be a non-instantaneous slide type. The portable cleaning implement includes a rechargeable battery of a size and type not disclosed. However, the size and shape of the battery shown in the figure appears to be that of a battery that is not readily available to the general public. The Sandt brush seems to accept torque in a similar way as the Dolor brush. That is, although none of the references give dimensions, the Sandt brush appears to accept torque with a slightly larger moment arm than the root hexagonal male member. However, Sandt's brushes include a relatively thin shaft, where harmful stresses due to torque can be concentrated.

  Moreover, neither Root, Dolor, nor Sandt disclose or suggest a convenient storage means. Sandt discloses a storage case. However, the storage case will be larger than the tools disclosed by Sandt and will take prohibitive amounts of counter space. Therefore, Sandt suggests attaching the case to the wall. However, attaching a case to the kitchen wall for storing kitchen utensils can impair the appearance of the kitchen and can be labor intensive for consumers. In addition, many people, such as tenants, are prohibited from making such changes to apartments or other leased spaces.

  Therefore, battery-operated handheld cleaning tools that are powered by commonly available batteries are desired. There is a need for a hand-held cleaning tool that is actuated by a momentary switch that automatically stops power supply when the tool is released. In addition, a cleaning tool is desired that transmits lower stress to the cleaning head, thereby extending the life of the cleaning head. Furthermore, a cleaning tool that can be conveniently stored when not in use is desired.

  Referring to FIGS. 1-3, an ergonomic battery operated cleaning tool 100 includes a housing 102 and a cleaning head 104. The housing can be divided into sections. For example, the housing 102 includes a lower housing or power compartment 106 and an upper housing or transmission module 108. Lower housing 106 and upper housing 108 include screws 110 and 112, respectively. The screws 110, 112 are used to connect the upper housing or transmission module 108 to the lower housing or power compartment 106. The lower housing or power compartment 106 is sized to accommodate at least one readily available battery. For example, the power compartment can be sized to accommodate AAA batteries, AA batteries, AAA batteries, single batteries, or 9V batteries. Both disposable and rechargeable batteries are available in these sizes. Furthermore, chargers for rechargeable batteries of these sizes are also readily available.

  A typical lower housing or power compartment 106 is sized to accommodate four AA batteries. By sizing the power compartment to accommodate four AA batteries 114, the lower housing or power compartment is 3,000 milliamp-hours (mA-) (using commonly available alkaline manganese batteries). hr) It is possible to include an ergonomic grip 116 while providing a 6 volt power supply with capacity.

  Other power sources may be selected. However, when other power sources are selected, it may generally be necessary to reduce the ergonomic features of the cleaning tool 100, particularly the grip 116. For example, the grip 116 may need to be wider to accommodate a single battery or a single battery. Furthermore, accommodating larger cells (single or single) may require more complex configurations. For example, when the power source includes two C-type AA batteries, it may be necessary to pass a conductor from the contact at the bottom end 118 to the motor first terminal 120.

  In an embodiment sized to accommodate four AA batteries, the spring contact plate 122 located at the bottom end 118 of the housing 102 is held in place by the spring contact cover 123. For example, the spring contact cover is snapped into a groove inside the bottom end 118 of the housing. The spring contact cover may include marks that indicate the proper orientation of the battery. Alternatively, the spring contact plate 122 and / or the cover 123 may be glued in place. Spring contact 122 completes the series connection of four AA batteries 114. Thus, four appropriately mounted batteries 114 provide positive and negative power transfer terminals 124, 126 from the battery itself at a convenient location within the housing 102.

  Electric power is taken from the power transmission terminals 124, 126 and transmitted to the motor 128 via the contacts 130, 132. The contacts 130 and 132 are supported by a contact holder 134. The contact holder 134 can be fixed to the housing 102. For example, the contact holder 134 can be attached to the lower housing or power compartment 106 with an adhesive or fastener.

  In the exemplary embodiment, contact holder 134 is attached to motor 128. For example, a fastener such as a screw 136 is used to secure the contact holder 134 to the rear end 138 of the motor 128. The motor is associated with the upper housing 108 as will be described in more detail below in the illustrated embodiment. Therefore, the contact holder 134 is not attached to the lower housing. Instead, the contact holder 134 (along with a portion of the motor 128) only slides in place within the lower housing 106. For example, a key arrangement (not shown) such as a tongue formed in the lower housing 102 and a groove included in the contact holder 134 ensures that the contact holder 134 is attached in the proper orientation, and the contact holder 134 and the motor 128 are It is prevented from rotating in the housing 102 during operation. For example, the key arrangement ensures that the contacts 130, 132 are aligned and engaged with the power terminals 126, 124, respectively.

  However, when attached, the contact holder 134 is sandwiched between the positive and negative power transfer terminals 124, 126 of the motor 128 and battery 114 set. A first contact 130 is disposed on the contact holder to provide a connection, for example, between the negative power transfer terminal 126 and the first motor terminal 120. The switch contact 132 is disposed and supported by the contact holder 134 so as to contact the positive power transmission terminal 124, for example. The switch contact 132 overlaps with either the second motor terminal 140 or the contact plate 142, which is pressed by, for example, the contact holder 134 to contact the second motor terminal 140. The switch contact 132 is elastically biased away from the second motor contact 140 and / or the contact plate 142. The contact holder 134 is arranged and oriented such that the switch contact 132 is adjacent to the switch opening 144 of the housing 102, for example by a key arrangement (not shown). For example, the opening 144 is in the lower housing or power compartment 106. A button 146 is attached adjacent to the spring contact 132. For example, the buttons are made of a resilient material such as rubber, plastic, or spring metal. Preferably, the button 146 seals the opening 144. When the button 146 is pressed, the button 146 contacts the spring contact 132 and presses it against the second motor contact and / or contact plate 142, thereby completing the power circuit and transferring power to the motor 128. .

  The motor 128 is attached to the housing 102. For example, if the contact holder 134 is secured to the lower housing or power compartment 106, attaching the motor 128 to the contact holder 134 with screws 136 is sufficient to secure the motor 128 to the lower housing or power compartment 106. obtain. Alternatively, the motor 128 can be secured to a portion of the housing 102 using additional brackets, fasteners, or adhesives.

  In the exemplary embodiment, motor 128 is indirectly attached to the upper housing or transmission module 108. For example, the motor mount 148 is fixed to the motor 128 with a fastener such as a screw 149. Alternatively, the motor mount 148 can be secured to the motor 128 using an adhesive. The motor mount 148 includes a tab or swaging cam 150. Tab 150 is received or snapped into slot 152 in peripheral gear housing 154. The peripheral gear housing 154 includes gear teeth (not shown) on its inner wall (not shown). An outer bushing 156 is secured in the peripheral gear housing 154. The outer bush 156 is made of metal, for example. The outer bushing is, for example, a friction fit or glued in the peripheral gear housing 154. An inner bushing 157 is friction fitted, glued, or otherwise secured to a portion of the transmission output shaft 158. The transmission output shaft 158 and the inner bushing 157 are mounted within the outer bushing 156 and the peripheral gear housing 154. The outer surface of the inner bushing 157 engages the inner surface of the outer bushing 156. A lubricant such as grease or petroleum jelly may be included between them. The peripheral gear housing 154 and associated components are inserted into the upper housing or transmission module 108. When so installed, the output portion 160 of the output shaft 158 extends through the peripheral gear housing 154 and the output opening 162 at the distal end 164 of the upper housing or transmission module 108. A seal 166 mounted around the output portion between the output portion 160 and the output opening 162 prevents liquid and crushed debris from entering the housing 102. Pins 168 secure hub 170 to output portion 160 of transmission output shaft 158. Pin 168 extends through first mounting opening 172 in shaft collar 174 of hub 170. Pin 178 also extends through second mounting opening 176 in output portion 160 of transmission output shaft 158. Pin 168 is held in place by a friction fit or adhesive. Alternatively, pin 168 is a cotter pin, screw, or other fastening means.

  The transmission output shaft is connected to the output 178 of the motor 128 by a mechanism or transmission 180. For example, a pinion gear 182 is attached to the output shaft 184 of the motor 128. The pinion gear 182 meshes with the first set of planetary gears 186. The first set of planetary gears 186 is supported by a first gear holder 188 and held in place by a gear holding plate 187. The first gear holder 188 includes a second pinion gear 190. The second pinion gear 190 meshes with the second set 192 of planetary gears. The second set of planetary gears 192 is supported by the second gear holder 194 and held in place by the flange portion of the first gear holder 188. The second gear holder 194 is attached to the transmission output shaft 158. For example, the second gear holder 194 is integrally formed with the proximal end 196 of the transmission output shaft 158. An alignment bushing 197 is attached to or molded into the second gear holder 194 or proximal end 196 of the transmission output shaft 158. The alignment bushing 197 is coaxial with the transmission output shaft 158. An alignment pin 198 is received in the alignment openings 200, 201 of the first pinion gear 182 and the alignment bushing 197. The alignment pin 198 is coaxial with and aligns the motor 128, the first pinion gear 182, the first gear holder 188, and the second gear holder 194.

  Alternatively, the alignment pin can be an integral component additionally molded to the transmission output shaft 158. For example, including alignment pins 198 as a molded component of the transmission output shaft 158 facilitates modular assembly of the cleaning tool 100 when the motor 128 is installed in the lower housing 106.

  In operation, when the button 146 is depressed, the elastic bias of the switch contact 132 is lost and the switch contact 132 engages the second motor terminal 140 or contact plate 142, thereby completing the power circuit. The electrical energy is transmitted from the battery 114 to the motor 128. The motor output shaft rotates at the output speed of the motor. The first set of planetary gears 186 engages the gear teeth (not shown) of the first pinion gear 182 and the peripheral gear housing 154. The rotation of the motor output shaft 184 causes the first pinion gear 182 to rotate. The rotation of the first pinion gear 182 causes the first set of planetary gears 186 to circulate around the first pinion gear 182 and the first pinion gear 182 to rotate between the first pinion gear 182 and the first planetary gear 186. The first gear holder 188 is driven at a reduced speed and increased torque due to one gear ratio. Similarly, the second pinion gear 190 is driven by the rotation of the first gear holder 188. The rotation of the second pinion gear 190 causes the second set 192 of planetary gears to circulate around the second pinion gear 190 and drives the second gear holder 194 so that the second pinion gear 190 and The second gear ratio between the second planetary gear 1192 and the second planetary gear 1192 is rotated at a further reduced speed and further increased torque. The rotation of the second gear holder 194 causes the attached transmission output shaft 158 to rotate. The rotation of the transmission output shaft 158 rotates the hub 170 as well as the attached cleaning head 104.

  The cleaning head, such as the cleaning head 104, is held at an appropriate position by the swaging cam 202. The swaging cam is attached to the transmission output shaft 158. For example, the swaging cam is molded into and integral with the distal end 204 of the transmission output shaft 158.

  It may be important to prevent water or other contaminants from entering the housing 102 of the cleaning tool 100. Thus, as described above, the cleaning tool includes a seal 166 to prevent water or contaminants from entering the housing 102 near the point where the transmission output shaft 158 extends out of the housing 102. An O-ring 203 seals the peripheral gear housing 154 against the upper housing or inner wall of the transmission module 108. Furthermore, as explained above, the button 146 also performs a sealing function. Alternatively, button 146 may have additional sealing components associated therewith. Where the housing 102 includes multiple sections, such as a lower housing or power compartment 106 and an upper housing or transmission module 108, a sealing component such as a gasket 206 should be included therebetween. If the housing 102 includes a removable battery door 208 for accessing the power source or battery 114, a sealing element such as an O-ring 210 should be included therein.

  Referring to FIGS. 4A, 4B, 5A, and 5B, a wide variety of working heads, such as the cleaning head 104, can be removably connected to the hub 170 to complete the cleaning apparatus 100. For example, the cleaning head 104 can be a pan polisher 404, a glass washer 410, a bottle washer 420, or a universal brush 430. Each work head includes an element for a specific work. For example, the pan polisher 404 includes relatively short and hard abrasive bristles 440. Pot polishing is expected to be the most demanding application for the cleaning apparatus 100. For example, pan polishing may require the pan polishing head 404 to be pressed with a relatively high level of force against the work piece, for example, a cooking pan having a stubbornly stuck meal. Thus, to minimize cleaning head deflection, the pan polishing head 404 includes a relatively short and sturdy body 444. Other work pieces, such as drinking glasses, are less likely to require sophisticated cleaning efforts associated with the pan. Nevertheless, glass tableware presents a unique set of cleaning challenges. For example, glass cleaning may include a long throat that makes it difficult to reach the indentation. Thus, the glass washer 410 includes a long and narrow body 448 and some softer hair 452 compared to the relatively hard hair 440 of the pot polisher. The long body 448 and the relatively soft bendable hair 452 allow the glass washer 410 to reach and clean parts of the work piece that may not be accessible by other work heads.

  The bottle washer 420 includes a mechanism suitable for cleaning bottles such as baby bottles. Cleaning individual baby bottles is unlikely to be a particularly difficult task. However, where there is one baby bottle, it is likely that there are many other baby bottles. Thus, a useful jarwasher quickly contacts all parts of the inner surface of the baby bottle to wipe off any remaining dry or milk powder. Thus, the bottle washer 420 includes a number of individual brush filaments 464 distributed along the flexible wire shaft 468 and at the distal end 470 of the shaft. The wire shaft 468 is longer than a typical baby bottle. The brush filaments 464 are distributed along a portion of the shaft that is at least as long as a typical baby bottle depth. The brush filament 464 is relatively soft and can be targeted for wiping rather than rubbing. The bottle washer 420 includes a short and sturdy connector portion 472 for connecting the wire shaft 468 to the hub 170.

  The general-purpose cleaning head 430 has an intermediate length, and the mechanism of the pot polisher 404 and, for example, the mechanism of the glass cleaner 410 can be combined. For example, the relatively hard hair of the pot polisher 404 and the somewhat softer hair 452 of the glass washer 410 can be included. The body portion 484 of the universal cleaning head 430 can be somewhat longer than the short and sturdy body 444 of the pan polisher 404.

  Referring to FIG. 6 with continued reference to FIGS. 4A, 4B, 5A, and 5B, the working heads, such as cleaning heads 104, 404, 410, 420, and 430, together have some type of mechanism. . For example, all working heads include a connector section 610. Connector section 610 includes a socket element 164 centered on the longitudinal axis 168 of the cleaning head. The socket includes a beveled front edge 622 and a beveled rear edge 624. Further, the connector section 610 includes a ring of torque receiving teeth 630. The ring of torque receiving teeth is concentric with the socket 614 about the longitudinal axis 618 of the cleaning head. In the exemplary embodiment, socket element 614 is recessed into the cleaning head relative to the ring of torque receiving teeth 630. For example, there are 8 torque receiving teeth in the ring. In some embodiments, there are only four torque receiving teeth. There is an interdental space 634 between adjacent torque receiving teeth. In the exemplary embodiment, there are eight interdental spaces 634. In some embodiments, there are four interdental spaces. Torque receiving teeth 630 extend from the ring foundation 638.

  As described above, the connection hub 170 includes a collar 174 fitted over the output portion 160 of the transmission output shaft 158. A pin 168 secures the collar 174 and thus the hub 170 to the transmission output shaft 158. The hub 170 also includes, for example, four torque transmission arms 644.

  During the installation or connection process, the swaging cam 202 of the transmission output shaft distal end 204 contacts the beveled leading edge 622 of the socket 614. As the meshing pressure increases, the swaging cam 202 deflects inward toward the working head longitudinal axis 618. Eventually, the swaging cam slides on the beveled trailing edge 624 of the socket and expands outward away from the longitudinal axis 618 to tightly engage the inner shoulder 650 of the socket 614, thereby The working head is pulled toward the hub 170 and the head is fixed as a part of the cleaning device 100.

  During this connection or meshing process, torque transmitting arms 644 are received in at least some of the interdental spaces 634. If the torque transfer arm 644 cannot be received in the interdental space 634 due to the initial deviation, the working head can be slightly twisted until the torque transfer arm 644 and the interdental space 638 are properly aligned.

  As explained above, when the transmission output shaft 158 is driven and rotated by the motor 128 and transmission or drive mechanism 180, the hub 170 is also driven by the pin 168 connecting the hub 170 to the transmission output shaft 158. Driven to rotate. Therefore, the torque transmission arm 644 is also driven to rotate. By the time the working head is pressed against the work piece, the torque transmitting arm 644 is driven against each tooth 630 of the torque receiving ring, and the working head is driven to rotate. The ring of torque receiving teeth 630 is spaced radially away from the longitudinal axis 618 of the working head. For example, the outer diameter of the ring of torque receiving teeth 630 can be about 1 inch. The torque transmitting arm 644 extends far from the longitudinal axis 648 of the cleaning device 100. For example, the torque transmission arm 644 extends from the hub 174 to the inner wall 652 of the hub 170. For example, the inner wall 652, and thus the distal end 656 of the torque transfer arm, is about a 1/2 inch radius from the longitudinal axis 648 of the cleaning device 100. The ring torque receiving teeth 630 are engaged at the distal end 656 of the arm 644 by a torque transmission arm or a delivery arm 644. The resulting moment arm allows torque transmission to the work head with a reduced level of stress on the torque receiving element of the work head as compared to the stress level transmitted in prior art instruments. In addition, the radius of connecting elements, such as hub 170 and work head connector section 610, increases, allowing the use of additional materials in their manufacture, thereby cleaning while maintaining an ergonomic design. The overall durability of the device 100 is enhanced.

  Referring to FIG. 7, the housing 102 has a generally cylindrical shape. However, in part, it tapers from a cylindrical shape to provide an ergonomically comfortable design. For example, a portion of the housing 102 is tapered to provide an ergonomic grip 116. For example, the gripping portion 116 can have a rounded rectangular cross section. The grip 116 has a length 710 that is at least sufficient to fit comfortably within the intended user's hand 714. For example, the length 710 is from about 3 inches to about 5 inches. In one embodiment, the length 710 is about 3.5 inches. This length allows sufficient space for the four gripping fingers 718 of the intended user's hand 714 to fit comfortably into the grip 116 while allowing a compact and comfortable overall length with respect to the housing 102. provide. Similarly, the grip width 722 and height 726 allow the grip 616 to fit comfortably within the palm 730 of the intended user's hand 714 and the four gripping fingers 718 to grip. It is selected so that it can be wound comfortably and reliably around the part. Moreover, in the exemplary embodiment, the length 710, width 722, and height 726 of the gripper 116 is such that the inner portion or chamber within the gripper 116 is a power source, eg, four commonly available AA batteries. 114 is selected so that it can be accommodated.

  In an exemplary embodiment, the grip width 722 is about 1 inch. For example, in one embodiment, the grip 116 has a tapered width. The width of the grip 116 varies from about 0.98 inches to about 1.1 inches. The grip height 726 is about 1.4 inches. For example, in one embodiment, the height of the grip 116 is tapered. The height of the gripping portion 116 varies from about 1.34 inches to about 1.525 inches.

  An activation button 146 is proximate the first or proximal end 731 of the grip 116. The button 146 is arranged such that the thumb 734 of the hand 714 holding the grip 116 can comfortably operate the cleaning device 100 by pressing the button 146. For example, the center 738 of the button 146 is about 3/4 inch to about 1 inch and is spaced 742 from the first end of the gripper 116. It should be noted that the designation of the position of the first end of the grip is somewhat arbitrary. Some readers consider that the button 146 is within a differently defined gripping portion of the cleaning apparatus 100. The above description is intended to be representative only and is not intended to limit the invention.

  When the housing 102 includes multiple sections, such as a lower housing or power compartment 106 and an upper housing or transmission module 108, the cleaning device 100 can be easily adapted to a particular cleaning operation. For example, when the cleaning device 100 is intended for kitchen cleaning operations such as washing dishes, glasses, and pots, the upper housing or transmission module 108 can have a relatively short length 750. One embodiment directed to these operations includes an upper housing having a length 750 of approximately 2½ inches.

  When the cleaning apparatus 100 targets other operations, the upper housing 108 may include a mechanism that targets those operations. For example, when the cleaning apparatus 100 is intended for cleaning the shower or bathtub area, the length 750 of the upper housing 108 can be longer. For example, the length 750 of the upper housing 108 can be selected such that the reach of the entire cleaning device 100 is longer. For example, an overall length of the cleaning device of about 14 inches to about 40 inches can be used to clean the adjacent wall over the tab or without crouching or bending the knee. It can be aimed at cleaning the tab itself. Other sizes can be adapted for washing sinks or other bathroom equipment.

  When the housing 102 includes, for example, a lower housing 106 and an upper housing 108, the cleaning device can be further adapted to a particular cleaning operation. For example, pot polishing can be effective when high torque is transmitted to the cleaning head. On the other hand, the bottle cleaning can obtain an effect by high-speed brush rotation. Washing the bathroom bowl can be effected by a low brush rotation speed. Therefore, when the cleaning device should be directed to cleaning baked and burnt pans and other items, an upper housing with a high torque motor or transmission that decelerates and provides high torque is installed. Is possible. In contrast, an upper housing having a high speed motor or a low gear ratio can be used in combination with a bottle washing head such as the bottle washer 420, and as a result, the entire surface of the bottle can be wiped and washed quickly. The next bottle can be washed quickly.

  By including the stand, the ergonomic features of the cleaning device can be further enhanced. For example, referring to FIG. 9, the lower or bottom end 902 of the cleaning device 904 is similar to the cleaning device or tool 100 otherwise, but includes a stand and battery door combination 908. The combination of the stand and the battery door is dimensioned to provide a stable base for the cleaning device 904. For example, the combination of the stand and battery door 908 is dimensioned such that the cleaning device 904 can be stored in an upright position on a kitchen counter. For example, referring to FIG. 10, in one embodiment, the stand and battery door combination 908 includes a generally circular bottom 914. The generally circular bottom 914 has a radius 918 of about 1.054 inches. The wall 922 of the stand and battery door combination is centered on the longitudinal axis of the cleaning device 904 and has a spacing 934 of about 0.317 cm (0.125 inches) below the generally circular bottom 914. From the generally circular bottom 914 and curved toward the lower housing 105, with a radius 926 of approximately 1.063 from, making the stand and battery door combination 908 generally hemispherical. However, referring to FIG. 11, the rear portion 938 of the stand and battery door combination 908 includes a flat portion 942. For example, at the generally circular bottom 914, the flat portion 942 is spaced about 944 inches from the front portion 946 of the generally circular bottom 914 and is spaced apart from the generally circular bottom 914. It extends upwards substantially perpendicular to. The flat portion 942 lies in a plane that is substantially in contact with the widest portion (not shown) of the cleaning device 904. The flat portion 942 allows the cleaning tool or device 914 to be placed substantially flat against, for example, a cardboard or other backing of a blister pack product packaging. Further, the provision of a flat portion 942 allows the cleaning implement or device 904 to be stored out of the way near walls or other equipment, such as near a toaster or microwave oven.

  The stand and battery door combination 908 can be generally hollow to reduce weight and material costs. In that case, a cavity 950 is created in the generally hemispherical wall 922. The cavity 950 can be protected from dust and debris accumulation by a cover 954. For example, the cover 954 can be adhered to the remaining part of the combination 908 of the stand and the battery door. Alternatively, the cover may include snap fit means 958 for securing the cover 954 to the rest of the stand / battery door combination 908. Further, the cover can include means for attaching the spring contact.

  For example, referring to FIG. 12, a cover 1210 similar to the cover 954 of FIG. 9 includes a first or elliptical ridge 1214 on its inner surface 1216. The first raised portion is effective to be received in a friction fit or snap fit groove (not shown) in the body 1218 of the stand and battery door combination 1222. Further, the inner surface 1216 of the cover 1210 includes means for holding the spring contact 1230. For example, the means for holding the spring contact 1230 is a second or eight-shaped ridge 1234. The means for holding the spring contact 1230 cooperates with the opening 1238 in the bottom wall 1242 of the body 1218 of the stand and battery door combination 1222 to hold the spring contact 1230 in place. For example, the spring contact 1230 is glued or press-fit within the region of the second or eight-shaped ridge 1234. The cover 1210 and spring contact 1230 combination is secured to the body 1218 of the stand / battery door combination 1222 by, for example, gluing, friction fitting, snap fitting, or other means. In so securing the cover 1210 to the body, the first and second portions 1240, 1242 of the spring contact 1230 are positioned to extend through the opening 1238 in the bottom wall 1242 of the body. Further, the connecting portion 1244 of the spring contact 1230 is captured or sandwiched between the cover 1210 and the bottom wall 1242, thereby further holding the spring contact in place. In this regard, the bottom wall 1242 replaces or acts on a spring contact cover, such as the spring contact plate or cover 123 of the cleaning tool or apparatus 100 of FIG. In doing so, the inner surface 1250 of the bottom wall 1242 can carry a label or emboss or etch the mark. For example, the mark or label can include a description of battery attachment or orientation.

  Alternatively, the ergonomic features of the cleaning device are enhanced with a separable stand. For example, referring to FIG. 13, the first separable stand 1310 includes a socket 1314 sized and shaped to receive a cleaning implement or device. For example, the socket is sized and shaped to receive the cleaning tool or apparatus 100 bottom end 118 of FIGS. Other dimensions of the first separable stand 1310 may be similar to that of the stand and battery door combination 1222. One embodiment of the first separable stand 1310 includes a collar 1318 that extends upwardly from a socket 1314. The collar 1318 can provide additional stability by preventing the cleaning tool 100 from tilting out of the socket 1314.

  Referring to FIG. 14, the second separable stand 1410 includes a first socket 1414 sized and shaped to receive a cleaning tool or device. For example, the socket is sized and shaped to receive the cleaning tool or apparatus 100 bottom end 118 of FIGS. The second separable stand 1410 does not have a generally hemispherical shape. Instead, the second separable stand 1410 has a rectangular footprint and a wall 1418 that curves from the first long edge 1422 to the second long edge 1426 to provide a second separable stand 1410. Results in a semi-cylindrical shape. A second socket 1430 and a third socket 1434 are spaced apart on either side of the first socket. The second 1430 and third 1434 sockets are sized and shaped to receive the working head connector section 610.
