Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically to cleaning equipment. Background Technology

[0002] With the development of technology, cleaning robots and other cleaning equipment are becoming increasingly intelligent. Most cleaning equipment is equipped with a roller brush, drive wheels, and mop arranged from front to back, enabling it to perform cleaning tasks according to user instructions and greatly improving the user experience. However, cleaning robots and other cleaning equipment still have some shortcomings in actual use:

[0003] Because the cleaning coverage of the roller brush is less than that of the mop, some areas are missed. Dust and hair in these missed areas can get stuck in the mop, causing debris such as hair to clog the drain pipes and valves of the cleaning equipment, resulting in water leakage and reducing the reliability of the cleaning equipment.

[0004] Dust, hair, and other debris in the missed areas can adhere to the drive wheels, causing them to leave tire tracks on the cleaned floor and resulting in secondary contamination of the floor surface awaiting cleaning. Summary of the Invention

[0005] In view of this, the present invention provides a cleaning device to solve the problem of missed cleaning in existing cleaning devices.

[0006] A first aspect of the present invention provides a cleaning device, comprising: a body, two drive wheels disposed at the bottom of the body, the two drive wheels being spaced apart at the bottom of the body along the width direction; a mop disposed behind the two drive wheels, the mop being disposed at the bottom of the body along the width direction; and a roller brush disposed in front of the two drive wheels, the roller brush being disposed along the width direction of the body, one end of the roller brush blocking one side of a drive wheel and the mop in the running direction of the cleaning device, and the other end of the roller brush being provided with a side brush, the side brush blocking the other side of the other drive wheel and the mop in the running direction of the cleaning device.

[0007] Beneficial effects: The cleaning device of the present invention covers one side of a drive wheel and a mop with one end of the roller brush, and sets a side brush at the other end of the roller brush to cover the other side of the drive wheel and the mop, so that there are no missed areas of the drive wheel and the front end of the mop, reducing the impact of dust and debris in the missed areas on the mop and drive wheel.

[0008] Specifically, taking a sweeping and mopping robot as an example, the robot performs sweeping with a front roller brush and mopping with a rear roller mop. The side brush is located on the front side of the robot's bottom along the wall, the roller brush is located in front of the two drive wheels at the bottom of the robot, and the roller mop is located behind the two drive wheels at the bottom of the robot. The total width of the side brush and roller brush is L, the distance between the outer sides of the two drive wheels is D, and the length of the roller mop is X. The condition that needs to be met is L≥X≥D. The cleaning area of ​​the side brush covers part of the cleaning area of ​​the roller brush to prevent particles from being missed between the side brush and the roller brush. Furthermore, the path swept by the side brush and roller brush needs to completely cover the path of the roller mop and the two drive wheels. The roller mop needs to cover the distance on both sides of the drive wheels to avoid the phenomenon that the drive wheels press on the uncleaned areas and then leave tire tracks in the cleaned areas.

[0009] In one alternative embodiment, the other end of the roller brush is provided with a drive mechanism for driving the roller brush to rotate, and the bottom of the machine body is formed with an installation area for mounting the drive mechanism. The side brush is located in front of the installation area and blocks the installation area in the running direction of the cleaning equipment.

[0010] Beneficial effects: The side brush covers the entire installation area, reducing missed areas and minimizing dust and hair clogging the mop and drain pipes. It also reduces the accumulation of dust, hair, and other debris on the drive wheels, preventing tire tracks from being left on the cleaned surface.

[0011] In one alternative embodiment, the mop includes a roller mop, which is disposed at the bottom of the machine body along the width direction of the machine body and blocks the two drive wheels in the direction of operation of the cleaning equipment.

[0012] Beneficial effects: By blocking the two drive wheels in the direction of the cleaning equipment's operation, the roller mop can clean the wheel tracks left by the drive wheels during operation, thus reducing secondary pollution caused by the drive wheels during the cleaning process. Additionally, during the reverse operation of the cleaning equipment, the roller mop can clean the dust on the front side of the two drive wheels, thereby reducing dust adhesion to the roller mop.

[0013] In one alternative embodiment, the drive mechanism includes a roller brush motor and a transmission assembly connecting the roller brush motor and the roller brush, wherein the roller brush motor and / or the transmission assembly are disposed in the mounting area.

[0014] Beneficial effects: By placing the roller brush motor and / or transmission assembly in the installation area, the purpose of integrated distribution of components is achieved, reducing interference between the roller brush motor and / or transmission assembly and other components, and reducing the impact of other components in the cleaning equipment on the roller brush motor and / or transmission assembly.

[0015] In one alternative embodiment, when both the roller brush motor and the transmission assembly are located in the mounting area, the roller brush motor and the transmission assembly are located in the mounting area from the outside to the inside along the width direction of the machine body.

[0016] Beneficial effects: By arranging the roller brush motor and transmission components from the outside to the inside along the width of the machine body within the installation area, with the roller brush motor positioned horizontally or vertically, this transmission method is simple and reliable, requiring no additional steering mechanism and improving the operational stability of the drive mechanism. Furthermore, it reduces interference between the drive mechanism and other components outside the installation area, achieving modular and compact assembly of the cleaning equipment.

[0017] Furthermore, in order to reduce the area occupied by the roller brush motor and transmission components in the installation area, the roller brush motor can be set as a disc motor, and the transmission components can be set as disc couplings. This reduces the lateral area of ​​the installation area, alleviates the cleaning pressure of the side brushes, and thus reduces the occurrence of missed cleaning in the installation area by the cleaning equipment.

[0018] In one alternative embodiment, with the transmission assembly located in the mounting area, the roller brush motor is placed vertically along the height direction of the cleaning equipment and positioned above the mounting area along the height direction of the cleaning equipment.

[0019] Beneficial effects: By positioning the roller brush motor above the installation area along the height of the cleaning equipment, the lateral area occupied by the transmission components in the installation area can be reduced, thereby reducing the overall lateral area of ​​the installation area, alleviating the cleaning pressure on the side brushes, and thus reducing the occurrence of missed areas in the installation area by the cleaning equipment.

[0020] Specifically, the drive shaft of the roller brush motor extends downward to the other end of the roller brush, and the transmission assembly includes a gear mechanism located at the other end of the roller brush. The other end of the roller brush is provided with a gear shaft that cooperates with the gear mechanism. The gear mechanism and the gear shaft are driven by bevel gears to achieve the purpose of steering transmission.

[0021] In one alternative embodiment, when the transmission assembly is located in the mounting area, the roller brush motor is placed laterally along the width direction of the cleaning equipment, and the roller brush motor is located inside the mounting area and arranged side by side with the roller brush.

[0022] Beneficial effects: By placing the roller brush motor on the inside of the installation area and side by side with the roller brush, the area occupied by the transmission components in the installation area can be reduced, thereby reducing the overall area of ​​the installation area and relieving the cleaning pressure on the side brush, thus reducing the occurrence of missed cleaning in the installation area by the cleaning equipment.

[0023] Specifically, the drive shaft of the roller brush motor extends to the other end of the roller brush, and the transmission assembly includes a gear mechanism located at the other end of the roller brush. The other end of the roller brush is provided with a gear shaft that cooperates with the gear mechanism. The drive shaft of the roller brush motor is connected to the gear mechanism, and the gear mechanism drives the roller brush to rotate through the gear shaft.

[0024] In one alternative implementation, when the roller brush motor is located in the mounting area, the transmission assembly is located inside the mounting area and embedded in the interior of the roller brush.

[0025] Beneficial effects: By embedding the transmission component inside the roller brush, the area occupied by the transmission component in the installation area can be reduced, thereby reducing the overall area of ​​the installation area, relieving the cleaning pressure on the side brush, and thus reducing the occurrence of missed cleaning in the installation area by the cleaning equipment.

[0026] Specifically, the roller brush is configured as a hollow cylinder, and the transmission assembly includes a gear mechanism disposed inside the hollow cylinder. The inner wall of the hollow cylinder is provided with an internal gear ring that cooperates with the gear mechanism. The drive shaft of the roller brush motor extends into the interior of the hollow cylinder and connects to the gear mechanism. The gear mechanism drives the roller brush to rotate through the internal gear ring.

[0027] In one alternative implementation, the transmission assembly includes a drive shaft mechanism, a gear structure, a pulley mechanism, or a worm gear mechanism.

[0028] Beneficial effects: Drive shaft mechanisms, gear structures, pulley mechanisms, or worm gear mechanisms are not only compact and space-saving, but also have the effects of steering and changing the transmission ratio. This facilitates the layout and assembly of the drive mechanism, reduces the area of ​​the installation area, and reduces the occurrence of missed cleaning by cleaning equipment in the installation area.

[0029] In one alternative implementation, the cleaning equipment includes a cleaning robot, a floor scrubber, or a vacuum cleaner.

[0030] Beneficial effects: Cleaning robots, floor scrubbers, or vacuum cleaners are all within the protection scope of the embodiments of this application. As for the specific structure of cleaning robots, floor scrubbers, or vacuum cleaners, it will not be described in detail here. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] In related technologies, cleaning equipment is equipped with a roller brush, drive wheels, and mop distributed from front to back. The roller brush is installed in the area between the two drive wheels. Due to the limited space in this area, the roller brush cannot be lengthened further. The length of the roller brush is shorter than that of the mop, resulting in the roller brush having a smaller cleaning coverage area than the mop, thus causing missed cleaning.

[0049] Dust and hair in missed areas can clog the mop, causing debris such as hair to block the drain pipes and valves of the cleaning equipment, leading to leaks and reducing its reliability. Dust and hair in these areas can also adhere to the drive wheels, leaving tire tracks on the cleaned surface and causing secondary contamination of the areas awaiting cleaning.

[0050] To address the issue of missed areas between the roller brush, drive wheel, and mop in cleaning devices such as robotic vacuum cleaners during operation, this application proposes extending one end of the roller brush to cover the drive wheel and mop, and installing a side brush at the other end of the roller brush. This side brush covers the drive wheel and mop, eliminating missed areas at the front of the drive wheel and mop, thereby reducing the impact of dust and debris in these missed areas on the mop and drive wheel.

[0051] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0052] like Figures 1 to 5As shown, according to an embodiment of the present invention, the present invention provides a cleaning device 100, which includes: a body 10, two drive wheels 20 disposed at the bottom of the body 10, the two drive wheels 20 being spaced apart along the width direction of the body 10; a mop 30 disposed behind the two drive wheels 20, the mop 30 being disposed at the bottom of the body 10 along the width direction of the body 10; and a roller brush 40 disposed in front of the two drive wheels 20, the roller brush 40 being disposed along the width direction of the body 10, and one end of the roller brush 40 blocking one side of a drive wheel 20 and a mop 30 in the running direction of the cleaning device 100, and the other end of the roller brush 40 being provided with a side brush 50, the side brush 50 blocking the other side of the other drive wheel 20 and a mop 30 in the running direction of the cleaning device 100.

[0053] In this embodiment, the cleaning device 100 covers one side of a drive wheel 20 and a mop 30 with one end of the roller brush 40, and provides a side brush 50 at the other end of the roller brush 40. The side brush 50 covers the other side of the drive wheel 20 and the mop 30, so that there are no missed areas at the front end of the drive wheel 20 and the mop 30, reducing the impact of dust and debris in the missed areas on the mop 30 and the drive wheel 20.

[0054] Specifically, the side brush 50 is located on the front side of the bottom of the robot vacuum cleaner along the wall, the roller brush 40 is located in front of the two drive wheels 20 at the bottom of the robot vacuum cleaner, and the roller mop 30 is located behind the two drive wheels 20 at the bottom of the robot vacuum cleaner. The total width of the side brush 50 and the roller brush 40 is L, the distance between the outer sides of the two drive wheels 20 is D, and the length of the roller mop 30 is X. The condition that needs to be met is L≥X≥D. The cleaning area of ​​the side brush 50 covers part of the cleaning area of ​​the roller brush 40 to prevent particles from being missed between the side brush 50 and the roller brush 40. In addition, the path swept by the side brush 50 and the roller brush 40 needs to completely cover the path of the roller mop 30 and the two drive wheels 20. The roller mop 30 needs to cover the distance on both sides of the drive wheels 20 to avoid the phenomenon that the drive wheels 20 press on the uncleaned areas and then leave tire tracks in the cleaned areas.

[0055] The following is through Figures 1 to 5 The specific structure and technical effects of the embodiments of this application are described in detail.

[0056] like Figures 1 to 5 As shown, in some embodiments, the other end of the roller brush 40 is provided with a drive mechanism for driving the roller brush 40 to rotate, and the bottom of the body 10 is formed with an installation area for installing the drive mechanism. The side brush 50 is located in front of the installation area and blocks the installation area in the running direction of the cleaning equipment 100.

[0057] In this embodiment, the cleaning range of the side brush 50 covers the installation area, thereby reducing the occurrence of missed areas by the cleaning equipment 100 in the installation area, and reducing the occurrence of dust and hair in the installation area getting stuck in the mop 30 and clogging the drain pipe and valve of the cleaning equipment 100. In addition, it reduces the occurrence of dust, hair and other debris in the installation area adhering to the drive wheel 20, causing the drive wheel 20 to leave tire tracks on the cleaned ground.

[0058] like Figures 1 to 5 As shown, in some embodiments, the mop 30 includes a roller mop 30, which is disposed at the bottom of the body 10 along the width direction of the body 10 and blocks the two drive wheels 20 in the running direction of the cleaning device 100.

[0059] In this embodiment, by blocking the two drive wheels 20 in the running direction of the cleaning device 100, the roller mop 30 can clean the wheel tracks left by the two drive wheels 20 during the operation of the cleaning device 100, thereby reducing secondary pollution caused by the drive wheels 20 during the operation of the cleaning device 100. Furthermore, during the reverse operation of the cleaning device 100, the roller mop 30 can clean the dust on the front side of the two drive wheels 20, thereby reducing the phenomenon of dust adhering to the roller mop 30.

[0060] like Figures 1 to 5 As shown, in some embodiments, the drive mechanism includes a roller brush motor 41 and a transmission assembly connecting the roller brush motor 41 and the roller brush 40, wherein the roller brush motor 41 and / or the transmission assembly are disposed in the mounting area.

[0061] In this embodiment, by placing the roller brush motor 41 and / or transmission assembly in the mounting area, the purpose of integrated distribution of components is achieved, reducing interference between the roller brush motor 41 and / or transmission assembly and other components, and reducing the impact of other components within the cleaning equipment 100 on the roller brush motor 41 and / or transmission assembly.

[0062] like Figures 1 to 5 As shown, in some embodiments, when both the roller brush motor 41 and the transmission assembly are located in the mounting area, the roller brush motor 41 and the transmission assembly are located in the mounting area from the outside to the inside along the width direction of the body 10.

[0063] In this embodiment, the roller brush motor 41 and the transmission assembly are arranged from the outside to the inside in the installation area along the width direction of the body 10. The roller brush motor 41 is arranged horizontally or vertically. This transmission method is simple and reliable, does not require an additional steering mechanism, and improves the working stability of the drive mechanism. In addition, it can reduce the interference of the drive mechanism with other components outside the installation area, realizing the modular and compact assembly of the cleaning equipment 100.

[0064] Furthermore, in order to reduce the area occupied by the roller brush motor 41 and the transmission assembly in the installation area, the roller brush motor 41 can be set as a disc motor, and the transmission assembly can be set as a disc coupling. This reduces the lateral area of ​​the installation area, alleviates the cleaning pressure of the side brush 50, and reduces the phenomenon of missed cleaning by the cleaning equipment 100 in the installation area.

[0065] like Figures 1 to 5 As shown, in some embodiments, when the transmission assembly is located in the mounting area, the roller brush motor 41 is placed vertically along the height direction of the cleaning device 100, and the roller brush motor 41 is located above the mounting area along the height direction of the cleaning device 100.

[0066] In this embodiment, by setting the roller brush motor 41 above the installation area along the height direction of the cleaning device 100, the lateral area occupied by the transmission components in the installation area can be reduced, thereby reducing the overall lateral area of ​​the installation area and relieving the cleaning pressure of the side brush 50, thus reducing the phenomenon of missed cleaning by the cleaning device 100 in the installation area.

[0067] Specifically, the drive shaft of the roller brush motor 41 extends downward to the other end of the roller brush 40. The transmission assembly includes a gear mechanism located at the other end of the roller brush 40. The other end of the roller brush 40 is provided with a gear shaft that cooperates with the gear mechanism. The gear mechanism and the gear shaft are driven by bevel gears to achieve the purpose of steering transmission.

[0068] like Figures 1 to 5 As shown, in some embodiments, when the transmission assembly is located in the mounting area, the roller brush motor 41 is placed laterally along the width direction of the cleaning device 100, and the roller brush motor 41 is located inside the mounting area and arranged side by side with the roller brush 40.

[0069] In this embodiment, by placing the roller brush motor 41 on the inner side of the installation area and arranging it side by side with the roller brush 40, the area occupied by the transmission components in the installation area can be reduced, thereby reducing the overall area of ​​the installation area and relieving the cleaning pressure of the side brush 50, thus reducing the phenomenon of missed cleaning by the cleaning equipment 100 in the installation area.

[0070] Specifically, the drive shaft of the roller brush motor 41 extends to the other end of the roller brush 40, and the transmission assembly includes a gear mechanism disposed at the other end of the roller brush 40. The other end of the roller brush 40 is provided with a gear shaft that cooperates with the gear mechanism. The drive shaft of the roller brush motor 41 is connected to the gear mechanism, and the gear mechanism drives the roller brush 40 to rotate through the gear shaft.

[0071] like Figures 1 to 5 As shown, in some embodiments, when the roller brush motor 41 is located in the mounting area, the transmission assembly is located inside the mounting area and embedded in the interior of the roller brush 40.

[0072] In this embodiment, by embedding the transmission component inside the roller brush 40, the area occupied by the transmission component in the installation area can be reduced, thereby reducing the overall area of ​​the installation area and relieving the cleaning pressure of the side brush 50, thus reducing the phenomenon of missed cleaning by the cleaning device 100 in the installation area.

[0073] Specifically, the roller brush 40 is configured as a hollow cylinder, and the transmission assembly includes a gear mechanism disposed inside the hollow cylinder. The inner wall of the hollow cylinder is provided with an internal gear ring that cooperates with the gear mechanism. The drive shaft of the roller brush motor 41 extends into the interior of the hollow cylinder and is connected to the gear mechanism. The gear mechanism drives the roller brush 40 to rotate through the internal gear ring.

[0074] like Figures 1 to 5 As shown, in some embodiments, the transmission assembly includes a rotating shaft mechanism, a gear structure, a pulley mechanism, or a worm gear mechanism.

[0075] In this embodiment, the drive shaft mechanism, gear structure, pulley mechanism, or worm gear mechanism are not only compact and occupy little space, but also have the effects of steering and changing the transmission ratio. This facilitates the layout and assembly of the drive mechanism, reduces the area of ​​the installation area, and reduces the phenomenon of missed cleaning by the cleaning equipment 100 in the installation area.

[0076] In some embodiments, the cleaning equipment 100 includes a cleaning robot, a floor scrubber, or a vacuum cleaner.

[0077] In this embodiment, the cleaning robot, floor scrubber, or vacuum cleaner provided in this application are all within the protection scope of this application. As for the specific structure of the cleaning robot, floor scrubber, or vacuum cleaner, it will not be described in detail here.

[0078] Taking a sweeping and mopping robot as an example, the robot performs sweeping operations with a front roller brush sweeping at 40 degrees and a rear roller mop mopping at 30 degrees.

[0079] Specifically, the cleaning system of the robotic vacuum cleaner includes a side brush 50, a roller brush 40, and a roller mop 30. During cleaning, the side brush 50 first sweeps up debris in corners, pushing it towards the roller brush 40, where it is then sucked into the dustbin by the rotating roller brush 40 and the suction port. The roller brush 40 effectively removes most dust and particulate matter from the cleaned floor, but a small amount of dust and stains may remain.

[0080] In this embodiment, a roller brush 40 is mounted in front of two drive wheels 20. A side brush 50 is mounted at the other end of the roller brush 40. A side brush motor 51 and a roller brush 40 motor are mounted on one side of the side brush 50. One end of the roller brush 40 can extend away from the roller brush 40 motor, and is not limited by the distance between the two drive wheels 20, extending all the way to the outside of the drive wheels 20 until one end of the roller brush 40 is close to the outer shell of the machine body 10. The roller mop 30 is located behind the drive wheels 20, and its length is greater than or equal to the distance between the two drive wheels 20. This embodiment combines the roller brush 40 and the side brush 50, resulting in a coverage width greater than the length of the rear roller mop 30, thereby reducing the phenomenon of the roller brush 40 missing particles from the roller mop 30.

[0081] The roller mop 30, located at the rear, cleans the floor after it has been swept in front. The clean water tank humidifies the roller mop 30, and the scraper blades scrub the floor after mopping. The scraped water is collected in the wastewater tank through a recycling device. Because very little debris remains on the floor after cleaning, there is no need for a blower, simplifying the entire mopping mechanism.

[0082] Specifically, the side brush 50 is located on the front side of the bottom of the robot vacuum cleaner along the wall, the roller brush 40 is located in front of the two drive wheels 20 at the bottom of the robot vacuum cleaner, and the roller mop 30 is located behind the two drive wheels 20 at the bottom of the robot vacuum cleaner. The total width of the side brush 50 and the roller brush 40 is L, the distance between the outer sides of the two drive wheels 20 is D, and the length of the roller mop 30 is X. The condition that needs to be met is L≥X≥D. The cleaning area of ​​the side brush 50 covers part of the cleaning area of ​​the roller brush 40 to prevent particles from being missed between the side brush 50 and the roller brush 40. In addition, the path swept by the side brush 50 and the roller brush 40 needs to completely cover the path of the roller mop 30 and the two drive wheels 20. The roller mop 30 needs to cover the distance on both sides of the drive wheels 20 to avoid the phenomenon that the drive wheels 20 press on the uncleaned areas and then leave tire tracks in the cleaned areas.

[0083] Furthermore, the cleaning equipment 100 also includes a mounting bracket and a drive mechanism. The roller mop 30 is mounted on the bottom of the mounting bracket, which can be mounted to the body 10 of the cleaning equipment 100 in a floating manner. The mounting bracket drives the roller mop 30 to contact or detach from the object to be cleaned by floating up and down. The drive mechanism includes a roller brush motor and a camshaft that is connected to the roller brush motor. Both the roller brush motor and the camshaft are mounted on the mounting bracket. The camshaft is provided with a cam that can press against the body 10. The roller brush motor can push the mounting bracket and the roller mop 30 upward by driving the cam downward to press against the body 10.

[0084] The present invention can drive the mounting bracket and the roller mop 30 to float up and down through the camshaft of the drive mechanism, thereby achieving the effect of automatically adjusting the lifting and lowering of the roller mop 30. Moreover, this adjustment scheme has the advantages of simple structure and high reliability.

[0085] Specifically, when the cleaning equipment 100 encounters a woolen object such as a blanket during operation, the detection sensor (which may be an ultrasonic sensor) used to detect the material of the object identifies the woolen object and then the cleaning equipment 100 automatically lifts the mop. After the mop is automatically lifted, it does not come into contact with the woolen object, thereby reducing the phenomenon of the mop contaminating the woolen object.

[0086] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
