[0046] Furthermore, by incorporating a cantilever wheel, this disclosure allows easily tangled objects such as hair to detach from the cantilever wheel's suspended end during rotation. This prevents the cantilever wheel from becoming clogged and malfunctioning due to tightly wrapped objects on its outer surface, and also avoids damage to the cleaning brush head or interference with the normal operation of cleaning components caused by hair or other easily tangled objects entering the gap between the cantilever wheel and the housing. Therefore, this disclosure, through the cantilever wheel design, effectively improves the cleaning efficiency and user experience of the cleaning brush head.

[0061] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0062] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0063] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0064] like Figures 1 to 6 As shown, some embodiments provide a cleaning brush head 012. This cleaning brush head 012 can be applied to cleaning equipment 01 such as vacuum cleaners, floor scrubbers, robotic vacuum cleaners, and vacuum-mop combos. This disclosure does not impose specific limitations on the cleaning equipment 01 using this cleaning brush head 012. The cleaning brush head 012 may include: a housing 1, a cantilever wheel 2, a wheel axle 3, and a cleaning component 5.

[0065] Among them, such as Figures 1 to 3 As shown, the housing 1 may have a receiving space 1a, which can be configured to receive a cleaning component 5. The cleaning component 5 can be rotatably connected to the housing 1, and can contact the surface to be cleaned for cleaning the surface. For example, the receiving space 1a may have a bottom opening, through which the cleaning component 5 can contact the surface to be cleaned. The cleaning component 5 can be a roller brush, but is not limited to this; it can also be a brush strip, side brush, etc., which can be selected and set according to the actual situation, all of which are within the protection scope of this disclosure.

[0066] The cantilever wheel 2 can be configured to contact the surface to be cleaned and can be connected to the housing 1 via the wheel axle 3. The cantilever wheel 2 can rotate around the wheel axle 3, thereby providing support for the entire cleaning brush head 012 and ensuring the stability of the cleaning brush head 012 during operation.

[0067] Furthermore, by incorporating the cantilever wheel 2, easily entangled objects such as hair can detach from the suspended end 23 of the cantilever wheel 2 during its rotation. This prevents the cantilever wheel 2 from becoming clogged and malfunctioning due to tightly wrapped objects on its outer surface. It also prevents hair from entering the gap between the cantilever wheel 2 and the housing 1, thus avoiding damage to the cleaning brush head 012 or affecting the normal operation of the cleaning component 5. Therefore, by incorporating the cantilever wheel 2, this disclosure effectively improves the cleaning efficiency and user experience of the cleaning brush head 012.

[0068] Furthermore, such as Figure 3 and Figure 4 As shown, the angle between the axis 31 of the wheel axle 3 provided in this disclosure and the surface to be cleaned is greater than or equal to 0 degrees and less than 15 degrees, for example: 0 degrees, 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, 14.5 degrees, etc. It should be noted that the surface to be cleaned mentioned here can be assumed to be a plane. This setting can improve the smoothness of operation and turning performance of the cleaning brush head 012, and can further improve the cleaning efficiency and user experience of the cleaning brush head 012.

[0069] For example, when the angle between the wheel axle 3 and the surface to be cleaned is 0 degrees, the wheel axle 3 can be kept parallel to the surface to be cleaned. This allows the side of the cantilever wheel 2 that is supported on the surface to be cleaned to be parallel to the surface to be cleaned, and the side of the cantilever wheel 2 that is supported on the surface to be cleaned can fit better with the surface to be cleaned, thereby improving the stability of the cleaning brush head 012 during movement.

[0070] When the angle between the axle 3 and the surface to be cleaned is greater than 0 degrees and less than 15 degrees, the cleaning brush head 012 will be more flexible when turning. An angle of 0 to 15 degrees allows the cantilever wheel 2 to better change its direction of movement when turning. If the angle between the axle 3 and the surface to be cleaned is greater than or equal to 15 degrees, the side of the cantilever wheel 2 supporting the surface will be difficult to adhere to, failing to prevent the entanglement of materials. Furthermore, the difficulty in adhering the side of the cantilever wheel 2 to the surface will significantly affect the stability of the cleaning brush head 012 during movement.

[0071] Meanwhile, when the aforementioned angle exists between the axle 3 and the surface to be cleaned, the cantilever wheel 2 can maintain good stability and passability on uneven surfaces. For example, on sloped or undulating ground, the contact pattern between the cantilever wheel 2 and the ground can be automatically adjusted by changing the angle between the axle 3 and the surface to be cleaned, preventing the cleaning brush head 012 from being obstructed. Furthermore, the angle between the axle 3 and the surface to be cleaned can decompose the weight of the cleaning brush head 012 itself and the forces generated during its movement. For example, on an inclined plane, this angle can decompose the weight of the device into two components: one perpendicular to the axis 31 of the axle 3 and the other along the extension direction T of the axis 31 of the axle 3, making the cleaning brush head 012 easier to control on inclined planes.

[0072] In some embodiments of this disclosure, such as Figure 2 and Figure 4 As shown, extending along the axis 31 of the axle 3 in the direction T, the cantilever wheel 2 may include at least a first wheel portion 21 and a second wheel portion 22. The first wheel portion 21 may be located near the midpoint of the cleaning brush head 012 in a first direction X relative to the second wheel portion 22. The first direction X may be perpendicular to the second direction Y and parallel to the surface to be cleaned, where the second direction Y may be the forward direction of the cleaning brush head 012. It is understood that the suspended end 23 of the cantilever wheel 2 may be located at the first wheel portion 21. The diameter of the first wheel portion 21 may be smaller than the diameter of the second wheel portion 22. The second wheel portion 22 may be configured to contact the surface to be cleaned, and there may be a gap between the first wheel portion 21 and the surface to be cleaned.

[0073] With this configuration, when the cantilever wheel 2 rotates, under the centrifugal force of the rotation and the friction between the second wheel portion 22 and the ground, the tangled material wrapped around the surface of the cantilever wheel 2 will be transported from the second wheel portion 22 to the first wheel portion 21, and then from the first wheel portion 21 to the suspended end 23, where it will detach from the cantilever wheel 2. Furthermore, since the suction port of the cleaning brush head 012 is located near the midpoint of the cleaning brush head 012 in the first direction X, when the first wheel portion 21 is closer to the midpoint of the cleaning brush head 012 in the first direction X relative to the second wheel portion 22, the distance between the tangled material detached from the first wheel portion 21 and the suction port is closer, making it easier for the suction port to draw the tangled material into the dust collection box under suction. This significantly improves the efficiency of tangled material removal and allows for timely cleaning of the tangled material detached from the cantilever wheel 2, effectively preventing the tangled material from re-contaminating the surface to be cleaned.

[0074] At the same time, when the second wheel 22 comes into contact with the surface to be cleaned, the second wheel 22 can be used to support the entire cleaning brush head 012, ensuring the support capability of the cantilever wheel 2 for the cleaning brush head 012 and ensuring the stability of the operation of the cleaning brush head 012.

[0075] Furthermore, the diameter of the first wheel portion 21 can gradually decrease along the third direction Z. Here, the third direction Z can be the direction in which the second wheel portion 22 points towards the first wheel portion 21. This arrangement allows the entangled material wrapped around the first wheel portion 21 to more easily detach under the centrifugal force of the rotating cantilever wheel 2, further improving the efficiency of entanglement removal.

[0076] In some embodiments, such as Figure 4 As shown, in the cross-section where the axis 31 of the wheel axle 3 is located, the included angle α between the outer circumferential surface of the first wheel portion 21 and the outer circumferential surface of the second wheel portion 22 can be greater than 0 degrees and less than or equal to 85 degrees. For example: 1 degree, 5 degrees, 10 degrees, 15 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, etc. This setting ensures that there is a sufficient included angle α between the outer circumferential surface of the first wheel portion 21 and the outer circumferential surface of the second wheel portion 22, so that the diameter of the first wheel portion 21 can gradually decrease along the third direction Z. This allows the entangled material wrapped around the first wheel portion 21 to be more easily detached under the action of the centrifugal force of the cantilever wheel 2, ensuring the efficiency of entangled material removal. At the same time, this arrangement can also avoid the problem that the diameter reduction rate of the first wheel part 21 is too large due to the large included angle α between the outer peripheral surface of the first wheel part 21 and the outer peripheral surface of the second wheel part 22, thus ensuring that the first wheel part 21 has high structural strength.

[0077] In some embodiments, such as Figure 4As shown, in the cross-section where the axis 31 of the wheel axle 3 is located, the upper or lower side of the first wheel portion 21 can be a straight line or a curve, that is, the rolling surface of the first wheel portion 21 can be a straight line or a curve. This type of cantilever wheel 2, where the rolling surface of the first wheel portion 21 is a straight line or a curve, can be a flat roller or a straight roller, mainly used to make straight or curved movements on a plane, ensuring that the wound material can be stably conveyed along a straight or curved direction.

[0078] In other embodiments, in the cross section where the axis 31 of the wheel axle 3 is located, the upper and lower sides of the first wheel portion 21 can be straight lines and curves, that is, the rolling surface of the first wheel portion 21 is straight lines and curves. Such a cantilever wheel 2 with the rolling surface of the first wheel portion 21 being straight lines and curves can be an irregularly shaped curved roller, etc.

[0079] In some embodiments, in the cross section where the axis 31 of the axle 3 is located, the upper or lower side of the first wheel portion 21 can be an arc. This configuration can make the surface of the first wheel portion 21 smoother, improve the guiding performance of the first wheel portion 21, and facilitate the movement and detachment of the wrapped object.

[0080] In some embodiments, in a plane passing through the axis 31 of the wheel axle 3 and perpendicular to the surface to be cleaned, the upper and lower sides of the first wheel portion 21 can both be arcs. This configuration can further improve the smoothness of the surface of the first wheel portion 21, making the guiding performance of the first wheel portion 21 better and more conducive to the movement and detachment of the entangled object.

[0081] In some embodiments of this disclosure, such as Figure 4 As shown, the dimension W of the second wheel portion 22 in the extension direction T of the axis 31 of the wheel axle 3 can be greater than or equal to 2 mm and less than or equal to 7 mm. For example, the dimension W of the second wheel portion 22 in the extension direction T of the axis 31 of the wheel axle 3 can be 2 mm, 3 mm, 4 mm, 4 mm, 6 mm, 7 mm, etc. This setting ensures that the second wheel portion 22 has sufficient dimension W in the extension direction T of the axis 31 of the wheel axle 3, giving it sufficient support strength and ensuring that the second wheel portion 22 can provide good support for the cleaning brush head 012. Furthermore, this setting also avoids increasing the overall dimension of the cantilever wheel 2 in the extension direction T of the axis 31 of the wheel axle 3 due to an excessively large dimension W of the second wheel portion 22, thus preventing the cantilever wheel 2 from occupying too much space and ensuring that the cantilever wheel 2 does not interfere with the cleaning work of the cleaning component 5, thereby ensuring the cleaning effect of the cleaning brush head 012.

[0082] In some embodiments, the widths of the first wheel portion 21 and the second wheel portion 22 can be equal. This arrangement allows the cantilever wheel 2 to have both good support capabilities and good anti-winding capabilities. However, this is not a limitation; the widths of the first wheel portion 21 and the second wheel portion 22 can also be unequal, and can be selected and set according to actual conditions, all of which are within the protection scope of this disclosure.

[0083] In some embodiments, such as Figures 3 to 5 As shown, the cantilever wheel 2 and the axle 3 can be detachably connected to facilitate the installation and replacement of the cantilever wheel 2. For example: Figure 3 and Figure 4 As shown, the cantilever wheel 2 and the axle 3 can be detachably connected by the pin 6, so as to reduce the steps and processes of connecting the cantilever wheel 2 and the axle 3 and improve the manufacturing efficiency of the cleaning brush head 012.

[0084] However, this is not the only option; the cantilever wheel 2 and the axle 3 can also be detachably connected using screws or other connectors. When using screws or other connectors for detachable connection between the cantilever wheel 2 and the axle 3, no clamping fixture is required. Therefore, using screws or other connectors for detachable connection between the cantilever wheel 2 and the axle 3 can save on connection costs, thereby reducing the manufacturing cost of the cleaning brush head 012.

[0085] In other embodiments, such as Figure 5 As shown, the cleaning brush head 012 can also be without the axle 3. The cantilever wheel 2 can be directly rotatably connected to the housing 1 via the pin 6, and the pin 6 can be used as the rotation axis of the cantilever wheel 2. With this configuration, the axle 3 can be eliminated from the cleaning brush head 012, thereby reducing the manufacturing cost of the cleaning brush head 012.

[0086] In some embodiments, the material of the cantilever wheel 2 may include metal and plastic. Alternatively, the material of the cantilever wheel 2 may include either metal or plastic. That is, the cantilever wheel 2 can be a metal wheel or a plastic wheel. Metal wheels can be made of metals such as aluminum alloy and stainless steel, which have high strength and hardness, can withstand greater weight and pressure, are not easily deformed, and wear relatively slowly. Plastic wheels are mainly made of plastics, such as polyurethane and nylon, which are relatively soft, have a certain degree of elasticity, and are lightweight. Plastic wheels have good shock absorption performance, can buffer vibrations, can assist the cleaning brush head 012 to move smoothly, and have low rolling noise, providing a relatively quiet working environment.

[0087] In some embodiments of this disclosure, such as Figure 1 and Figure 2 As shown, the accommodating space 1a also has a front opening 1b in front of the cleaning brush head 012 along the second direction Y, and the cantilever wheel 2 can be disposed in the front opening 1b. That is to say, the cantilever wheel 2 can be disposed in front of the cleaning component 5 in front of the cleaning brush head 012 along the second direction Y.

[0088] Once the tangled material detaches from the cantilever wheel 2, it can fall into the front opening 1b. The cleaning component 5, which rotates at high speed in the receiving space 1a, can directly roll up the tangled material that has fallen into the front opening 1b and suck it into the dust collection box through the suction port.

[0089] Furthermore, the cantilever wheel 2 can be connected to the side wall of the front opening 1b via the axle 3, which can prevent the cantilever wheel 2 from interfering with the cleaning work of the cleaning component 5 and also ensure a high connection stability between the cantilever wheel 2 and the housing 1.

[0090] The cantilever wheel 2 can have at least two, and the at least two cantilever wheels 2 can be respectively arranged on both sides of the cleaning member 5 along the midpoint of the cleaning brush head 012 in the first direction X, so as to improve the support capacity of the cantilever wheel 2 for the cleaning brush head 012.

[0091] The cleaning brush head 012 can be equipped with multiple cantilever wheel assemblies, each of which can have two cantilever wheels 2. The two cantilever wheels 2 can be respectively positioned on both sides of the midpoint of the cleaning component 5 along the first direction X of the cleaning brush head 012. This arrangement can further improve the support capacity of the cantilever wheels 2 for the cleaning brush head 012, and under the combined action of multiple sets of cantilever wheels 2, it can prevent hair and other entangled objects from wrapping around the cleaning component 5 or getting tangled in the gap between the cleaning component 5 and the housing 1. This ensures that the cleaning component 5 can work continuously and stably, guaranteeing the working stability and cleaning effect of the cleaning brush head 012.

[0092] In some embodiments, such as Figure 6 As shown, the cantilever wheel 2 can also be set behind the cleaning component 5 along the second direction Y of the cleaning brush head 012 to support the cleaning brush head 012 and ensure the stability and smoothness of the operation of the cleaning brush head 012.

[0093] In some embodiments, such as Figures 1 to 4 As shown, the cleaning brush head 012 may also include a blocking member 4, which may be disposed between the second wheel portion 22 and the housing 1. For example, the blocking member 4 may be sleeved on the axle 3 and disposed between the second wheel portion 22 and the side wall of the front opening 1b, but is not limited thereto. The blocking member 4 may be configured to prevent tangled material from entering the gap between the second wheel portion 22 and the housing 1, so as to avoid the problem that the cantilever wheel 2 cannot rotate normally due to dirt or tangled material being wrapped in the gap between the second wheel portion 22 and the housing 1. At the same time, it can also prevent dirt or tangled material from entering the receiving space 1a through the gap.

[0094] On the third direction Z, the blocking member 4 can fill the gap between the second wheel part 22 and the housing 1 to further prevent dirt or entanglement from getting tangled in the gap between the second wheel part 22 and the housing 1, and can also further prevent dirt or entanglement from entering the receiving space 1a through the gap.

[0095] In some embodiments, the blocking member 4 is a flexible member, and the blocking member 4 can be interference-fitted with the housing 1 and the second wheel portion 22. Alternatively, the blocking member 4 is a flexible member, and the blocking member 4 can be interference-fitted with the housing 1 or the second wheel portion 22. This configuration can improve the installation stability of the blocking member 4 and prevent the blocking member 4 from falling off during the operation of the cleaning brush head 012.

[0096] In some embodiments, such as Figure 4 As shown, the interference H1 between the blocking member 4 and the second wheel portion 22 can be 1 / 6 to 2 / 3 of the thickness H2 of the blocking member 4, for example: 1 / 6, 1 / 5, 1 / 4, 1 / 3, 1 / 2, 2 / 3, etc. When the interference H1 between the blocking member 4 and the second wheel portion 22 is less than 1 / 6 of the thickness H2 of the blocking member 4, it may not be able to prevent the tangled material from entering the gap between the second wheel portion 22 and the housing 1. When the interference H1 between the blocking member 4 and the second wheel portion 22 is greater than 2 / 3 of the thickness H2 of the blocking member 4, the cantilever wheel 2 may not be able to rotate freely or may have difficulty rotating during the movement of the cleaning brush head 012, which is not conducive to the tangled material detaching from the cantilever wheel 2. Preferably, the interference H1 between the blocking member 4 and the second wheel portion 22 can be 1 / 3 of the thickness H2 of the blocking member 4. In this case, the cantilever wheel 2 can rotate normally during the movement of the cleaning brush head 012 and can effectively prevent the tangled material from entering the gap between the second wheel portion 22 and the housing 1.

[0097] In some embodiments, the outer peripheral surface of the blocking member 4 may have a first distance L1 between it and the axis 31 of the wheel axle 3, and the outer peripheral surface of the second wheel portion 22 may have a second distance L2 between it and the axis 31 of the wheel axle 3. The first distance L1 may be less than the second distance L2. This arrangement can prevent the blocking member 4 from coming into contact with the surface to be cleaned, thus avoiding damage to the blocking member 4.

[0098] The difference between the first distance L1 and the second distance L2 can be greater than 0 mm and less than or equal to 3 mm. For example, 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc. This setting can avoid the difference between the first distance L1 and the second distance L2 being too large, which would result in a large step surface between the blocking member 4 and the second wheel part 22. This allows the material wrapped around the outer circumference of the blocking member 4 to be transported to the second wheel part 22 under the action of centrifugal force, and then transported to the first wheel part 21 through the second wheel part 22 for final detachment.

[0099] In some embodiments, the blocking member 4 may be a ring-shaped structural member made of materials such as felt, nylon, wool, acrylic and / or polyester, but is not limited thereto. The blocking member 4 may also be made of other materials, which may be selected and set according to the actual situation, and all of these are within the protection scope of this disclosure.

[0100] This disclosure also provides a cleaning device 01. The cleaning device 01 can be a vacuum cleaner, floor scrubber, robotic vacuum cleaner, vacuum and mop combo, etc., and this disclosure does not impose any specific limitations on it.

[0101] like Figure 7 As shown, the cleaning device 01 may include a handheld part 011 and a cleaning brush head 012. The operator can move and / or operate the cleaning device 01 by holding the handheld part 011. The cleaning brush head 012 may be the cleaning brush head 012 described above, and the handheld part 011 may be connected to the cleaning brush head 012.

[0102] It should be noted that the specific structure and beneficial effects of the cleaning brush head 012 have been described in detail in the above embodiments. Therefore, in this embodiment, the specific structure and beneficial effects of the cleaning brush head 012 will not be described again. Please refer to the specific description in the above embodiments, which are all within the protection scope of this disclosure.

[0103] The cleaning device 01 provided in this disclosure includes a cleaning brush head 012, such as Figures 1 to 6 As shown, the cleaning brush head 012 includes a housing 1, a cantilever wheel 2, and a wheel axle 3. The cantilever wheel 2 can be configured to contact the surface to be cleaned, thereby providing support for the entire cleaning brush head 012 and ensuring the stability of the cleaning device 01 during operation.

[0104] Furthermore, by incorporating the cantilever wheel 2, easily entangled objects such as hair can detach from the suspended end 23 of the cantilever wheel 2 during its rotation. This prevents the cantilever wheel 2 from becoming clogged and malfunctioning due to tightly wrapped objects on its outer surface. It also prevents hair from entering the gap between the cantilever wheel 2 and the housing 1, thus avoiding damage to the cleaning brush head 012 or affecting the normal operation of the cleaning components 5. Therefore, by incorporating the cantilever wheel 2, this disclosure effectively improves the cleaning efficiency and user experience of the cleaning device 01.

[0105] Secondly, this disclosure makes the angle between the axis 31 of the wheel axle 3 and the surface to be cleaned greater than or equal to 0 degrees and less than 15 degrees, which can improve the running stability and turning performance of the cleaning brush head 012, and further improve the cleaning efficiency and user experience of the cleaning device 01.

[0106] This disclosure also provides a cleaning system. For example... Figure 7As shown, the cleaning system includes a base station 02 and a cleaning device 01. The cleaning device 01 can be the cleaning device described above, and can be placed on or connected to the base station 02. The base station 02 can charge, collect dust, replenish water, and clean the cleaning device 01, or suck out the dirt stored in the cleaning device 01.

[0107] It should be noted that the specific structure and beneficial effects of the cleaning device 01 have been described in detail in the above embodiments. Therefore, in this embodiment, the specific structure and beneficial effects of the cleaning device 01 will not be described again. Please refer to the specific description in the above embodiments, which are all within the protection scope of this disclosure.

[0108] The cleaning system provided in this disclosure includes the cleaning equipment 01 described above, such as... Figures 1 to 6 As shown, the cleaning device 01 includes a housing 1, a cantilever wheel 2, and a wheel axle 3. The cantilever wheel 2 can be configured to contact the surface to be cleaned, thereby providing support for the entire cleaning brush head 012 and ensuring the stability of the cleaning system operation.

[0109] Furthermore, by incorporating the cantilever wheel 2, easily entangled objects such as hair can detach from the suspended end 23 of the cantilever wheel 2 during its rotation. This prevents the cantilever wheel 2 from becoming clogged and malfunctioning due to tightly wrapped objects on its outer surface, and also avoids damage to the cleaning brush head 012 or disruption of the cleaning component 5 caused by hair entering the gap between the cantilever wheel 2 and the housing 1. Therefore, by incorporating the cantilever wheel 2, this disclosure effectively improves the cleaning efficiency and user experience of the cleaning system.

[0110] Secondly, this disclosure makes the angle between the axis 31 of the wheel axle 3 and the surface to be cleaned greater than or equal to 0 degrees and less than 15 degrees, which can improve the running stability and turning performance of the cleaning brush head 012, and further improve the cleaning efficiency and user experience of the cleaning system.

[0111] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein.
