Description

Technical Field

[0001] The present disclosure belongs to the technical field of cleaning equipment, and specifically provides a cleaning system. Background Art

[0002] A cleaning robot is a type of robot that can intelligently clean a home environment. These include sweeping robots, mopping robots, and sweep-suction-mopping robots. To facilitate charging and / or cleaning operations, existing cleaning robots are typically equipped with a base station, which allows them to charge, clean their mopping parts, and vacuum dustbins.

[0003] For cleaning robots with mopping functions, the base station compatible with them has a cleaning tank for accommodating the mopping and wiping parts of the cleaning robot. The cleaning unit on the base station cleans the mopping and wiping parts in the cleaning tank, thereby achieving the function of automatically cleaning the mopping and wiping parts. However, during the cleaning process of the existing base station, the rotating mopping and wiping parts often throw out the dirty liquid in the cleaning tank, and even let it flow into the suction port of the cleaning robot. This will cause the cleaning robot to suck in the dirty liquid in the suction port when it performs the next vacuuming operation, causing damage to the dust collection system. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the wiping parts of the existing cleaning robot are prone to throwing out the dirty liquid in the cleaning tank of the base station when being cleaned by the base station, thereby causing the dirty liquid to flow into the dust suction port, the present disclosure provides a cleaning system, including a cleaning robot and a base station, the base station including a guide slope and a cleaning tank, the bottom of the cleaning robot is provided with a cleaning device, the cleaning robot docks on the base station through the guide slope so that the cleaning device cleans in the cleaning tank, the guide slope is provided with a positioning groove for accommodating the driving wheel of the cleaning robot, the bottom of the cleaning robot is provided with a shielding part, the driving wheel is parked in the positioning groove, and the shielding part abuts and cooperates with the guide slope to shield the cleaning liquid splashed from the cleaning tank when the cleaning device is cleaning.

[0005] Furthermore, the bottom of the cleaning robot is provided with a water retaining rib, a water retaining protrusion, or a water retaining area, and the water retaining rib, the water retaining protrusion, or the water retaining area forms the shielding portion.

[0006] Furthermore, the cleaning robot includes a cleaning component having a roller brush, and the shielding portion is arranged on the rear side of the roller brush in the forward direction of the cleaning robot.

[0007] Furthermore, the cleaning component can be arranged to float at the bottom of the cleaning robot, and the shielding portion is arranged on the cleaning component to float with the cleaning component.

[0008] Furthermore, the cleaning component also includes a roller brush cover, which includes a fixed frame fixedly connected to the cleaning robot body and a cover body connected to the fixed frame, and the cover body can float up and down relative to the fixed frame, and the shielding part is fixedly connected to the cover body so that the shielding part floats with the cover body.

[0009] Furthermore, the front end of the cover is hinged to the fixing frame, and the shielding portion is also fixedly connected to the fixing frame through its top end;

[0010] The shielding portion includes an elastic portion located between the fixing frame and the cover body, and the elastic portion is used to provide a downward force for the cover body so that the bottom end of the shielding portion abuts against the guide slope or the surface to be cleaned.

[0011] Furthermore, an elastic member is provided between the fixing frame and the cover body, and the elastic member is used to provide a downward force for the cover body so that the bottom end of the shielding portion abuts against the guide slope or the surface to be cleaned.

[0012] Furthermore, the guide slope is provided with an abutment portion cooperating with the shielding portion, and the abutment portion is a sealing surface provided on the top side of the guide slope; or,

[0013] The abutting portion is a retaining rib arranged on the top side of the guiding inclined surface.

[0015] Furthermore, a sealing portion is provided on the side wall of the cleaning tank, and the sealing portion abuts and seals against the cleaning robot in the cleaning tank to isolate the cleaning liquid below the sealing portion.

[0016] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of the present disclosure, by making the shielding part of the cleaning robot sealably abut against the abutting part of the base station, the shielding part can block the cleaning liquid splashed from the cleaning tank, thereby avoiding the situation where dirty liquid flows to the suction port of the cleaning robot and contaminates the suction port.

[0017] Furthermore, by providing a positioning groove for accommodating the driving wheel of the cleaning robot on the base station, when the driving wheel of the cleaning robot enters the positioning groove, the shielding part sinks and presses against the abutting part to shield the cleaning liquid splashing out of the cleaning tank.

[0018] Furthermore, by setting the roller brush cover as a fixed frame fixedly connected to the body of the cleaning robot and a cover body that can float up and down relative to the fixed frame, and fixing the shielding part to the cover body, the shielding part can move up and down with the floating of the cover body, thereby adapting to the surface to be cleaned with undulations, obstacles and / or steps.

[0019] Furthermore, by providing the shielding portion with an elastic portion located between the fixed frame and the cover body, the shielding portion can provide a downward force to the cover body through the elastic portion, so that the bottom end of the shielding portion abuts against the abutting portion of the base station, preventing the dirty liquid on the base station from entering the dust suction port; and the bottom end of the shielding portion abuts against the surface to be cleaned to pick up dirt on the surface to be cleaned.

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0040] The cleaning system of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the preferred embodiments of the present disclosure.

[0041] like Figure 1 As shown, the cleaning system of the present disclosure includes a base station 1 and a cleaning robot 2. The base station 1 is used to provide at least charging and cleaning services for the cleaning robot 2. The cleaning robot 2 is used to clean the surface to be cleaned. The cleaning robot 2 can return to the base station 1 for charging and / or cleaning according to user instructions or stored program instructions.

[0042] like Figure 1 and Figure 2 As shown, when the cleaning robot 2 walks near the base station 1, it docks with the base station 1 in a backward manner.

[0043] like Figures 1 to 3 As shown, the base station 1 mainly includes a base station body 11, a base 12, a cleaning tank 13, a scraping rib 14, a sealing portion 15, a charging terminal 16, a liquid supply unit and a dirt suction unit. Among them, the base 12 is located below the base station body 11 and is fixedly connected to the base station body 11 or made integrally therewith. The base 12 is used to guide the cleaning robot 2 to dock with the base station 1. The cleaning tank 13 is formed between the base station body 11 and the base 12. The cleaning tank 13 can accommodate a part of the cleaning robot 2 and is used to clean the cleaning robot 2. The scraping rib 14 is arranged in the cleaning tank 13 and protrudes upward from the bottom wall of the cleaning tank 13. The scraping rib 14 is used to scrape the wiping part 23 of the cleaning robot 2 to clean the wiping part 23 of the cleaning robot 2. The sealing portion 15 is arranged on the rear side wall of the cleaning tank 13 and is sealed against the circumferential surface of the cleaning robot 2 when the cleaning robot 2 is docked with the base station 1. The charging terminal 16 is also provided in the cleaning tank 13, and the base station 1 provides charging services for the cleaning robot 2 through the charging terminal 16. The liquid supply unit is used to provide cleaning liquid to the mopping and wiping parts 23 of the cleaning robot 2 to wet the mopping and wiping parts 23. The dirt suction unit is used to absorb the dirty liquid in the cleaning tank 13.

[0044] like Figure 1 and Figure 2 As shown, the base 12 is provided with a positioning groove 121 at the top of the guide slope 122, and the positioning groove 121 is used to accommodate the driving wheel 25 of the cleaning robot 2 (such as Figure 6 When the cleaning robot 2 is docked with the base station 1 , the driving wheel 25 of the cleaning robot 2 sinks into the positioning groove 121 .

[0045] The bottom of the cleaning robot is provided with a shielding portion, which abuts and cooperates with the guide slope when the driving wheel is parked in the positioning groove to block cleaning liquid splashing from the cleaning groove during cleaning by the cleaning device. When the driving wheel of the cleaning robot sinks into the positioning groove of the base station, the shielding portion of the cleaning robot sinks and seals against the top surface of the base station base, allowing the shielding portion to block dirty liquid thrown by the cleaning robot's mopping parts, thereby preventing the dirty liquid from flowing into the cleaning robot's suction port and contaminating the suction port.

[0046] Specifically, the bottom of the cleaning robot is provided with a water-retaining rib, a water-retaining protrusion, or a water-retaining area, which forms the shielding portion. That is, the shielding portion forms line contact, point contact, or surface contact with the guide slope to shield the cleaning liquid. The cleaning robot includes a cleaning assembly having a roller brush, and the shielding portion is provided behind the roller brush in the forward direction of the cleaning robot.

[0047] Furthermore, the cleaning robot includes a cleaning assembly, which includes a roller brush, and the shielding portion is disposed behind the roller brush in the forward direction of the cleaning robot. This prevents the shielding portion from interfering with the roller brush during cleaning. Preferably, the water retaining rib is made of an elastic material, such as silicone or plastic.

[0048] Preferably, the bottom wall of the positioning groove 121 is arc-shaped, that is, the positioning groove 121 is an arc-shaped recessed groove to adapt to the circumferential surface of the driving wheel 25 .

[0049] Continue reading Figure 1 and Figure 2 The top surface of the base 12 includes a guiding slope 122 and a sealing surface 123 as an abutment portion. The guiding slope 122 is used to guide the cleaning robot 2 into the base station 1, and the sealing surface 123 is connected to the shielding portion 242 (such as the shielding portion 242) of the cleaning robot 2. Figure 9 As shown in FIG, the sealing surface 123 is adapted to the front end thereof, and the front end of the sealing surface 123 is connected to the top end of the guiding inclined surface 122. Further, the top surface of the base 12 also has a retaining rib 124 located at the rear end of the sealing surface 123.

[0050] like Figures 1 to 3 As shown, the sealing portion 15 is an arc-shaped sheet structure to adapt to the circumferential surface of the cleaning robot 2. Of course, those skilled in the art can also set the sealing portion 15 to any other feasible shape according to the shape of the cleaning robot 2, such as a long sheet structure (the cleaning robot is a square column).

[0051] Preferably, the length of the sealing portion 15 is 1 / 5-1 / 3 of the circumference of the cleaning robot 2 to ensure that the sealing portion 15 and the cleaning robot 2 that are sealed together can isolate the cleaning liquid in the cleaning tank 13 below the sealing portion 15 .

[0052] More preferably, the width of the sealing portion 15 is in the range of 3 mm to 10 mm, such as 3 mm, 4.5 mm, 6.7 mm, 9 mm, etc.

[0053] like Figure 2 and Figure 3 As shown, the charging terminal 16 is movably disposed above the sealing portion 15 to prevent the charging terminal 16 from contacting the cleaning fluid below the sealing portion 15. Preferably, the charging terminal 16 can float forward and backward relative to the base station body 11 and up and down relative to the base station body 11, so that the contact between the charging terminal 16 and the cleaning robot 2 is flexible. This allows the driving wheel 25 of the cleaning robot 2 to enter the positioning groove 121, forcing the charging terminal 16 to move backward and downward relative to the base station body 11.

[0054] It will be understood by those skilled in the art that, when the driving wheel 25 of the cleaning robot 2 enters the positioning groove 121, the driving wheel 35 will move backward and downward simultaneously, causing the cleaning robot 2 to also move backward and downward, making it easier to force the charging terminal 16 to move backward and downward relative to the base station body 11.

[0055] Preferably, one end of the charging terminal 16 is pivotally connected to the base station body 11 , and the other end of the charging terminal 16 abuts against the power receiving terminal of the cleaning robot 2 , so that the charging terminal 16 can move rearward and downward relative to the base station body 11 in a swinging manner.

[0056] Refer to the following Figure 4 and Figure 5 The structure of the charging terminal 16 and the matching process with the cleaning robot 2 are described with examples.

[0057] like Figure 4 and Figure 5 As shown, the charging terminal 16 is pivotally connected to the base station main body 11, and a torsion spring is provided between the charging terminal 16 and the base station main body 11 so that the charging terminal 16 is kept in the normal state by the torsion spring. Figure 4 Position shown.

[0058] Continue reading Figure 4 and Figure 5, when the cleaning robot 2 on the surface to be cleaned moves onto the guiding slope 122 and moves forward along the guiding slope 122, the cleaning robot 2 on the guiding slope 122 is in an inclined state. As the cleaning robot 2 moves on the guiding slope 122, the cleaning robot 2 first abuts against the sealing portion 15, and then the cleaning robot 2 continues to move forward, squeezing the sealing portion 15 and causing the sealing portion 15 to deform. When the cleaning robot 2 moves to the edge of the positioning groove 121 (when it is about to enter the positioning groove 121 or has entered a small part of the positioning groove 121), the power receiving terminal of the cleaning robot 2 abuts against the charging terminal 16 (such as Figure 4 Then, as the driving wheel 25 of the cleaning robot 2 moves in the positioning groove 121, the motion state of the cleaning robot 2 is forward and downward. During this period, the charging terminal 16 abutting against the cleaning robot 2 rotates downward around its pivot axis (not marked in the figure) driven by the cleaning robot 2, and the protrusion (not marked in the figure) of the charging terminal 16 moves backward and downward relative to the base station body 11 (as shown in the figure). Figure 4 Shown location to Figure 5 As shown in the position), the protrusion of the charging terminal 16 and the power receiving terminal of the cleaning robot 2 are kept in close contact. Figure 5 As shown, when the cleaning robot 2 is stabilized at the lowest point of the positioning groove 121, the wiping member 23 of the cleaning robot 2 is located at the cleaning groove 13, and the cleaning robot 2 is tightly in contact with the sealing portion 15. At the same time, the rotating charging terminal 16 drives the torsion spring to rotate, thereby giving the charging terminal 16 a chance to return to its initial position (by Figure 5 The position shown is restored to Figure 4 The force of the charging terminal 16 squeezes the cleaning robot 2 to promote the tightness of the docking between the two.

[0059] Although not shown in the figure, the liquid supply unit includes a clean water tank and a delivery pump detachably mounted on the base station body 11 . The delivery pump can deliver clean cleaning liquid in the clean water tank to the cleaning tank 13 to soak the wiping member 23 on the cleaning robot 2 .

[0060] Although not shown in the drawings, the sewage suction unit includes a sewage tank and a suction pump. The suction pump can extract the sewage in the cleaning tank 13 into the sewage tank.

[0061] like Figure 1 、 Figure 2 and Figure 6 As shown, the cleaning robot 2 includes a cleaning robot body 21, a liquid storage tank 22, a dust suction system (not shown in the figure), a cleaning device (not shown in the figure), a cleaning component (not shown in the figure), a driving wheel 25 for driving the cleaning robot 2 to move, and a guide wheel 26 for guiding the moving direction of the cleaning robot 2.

[0062] Continue reading Figure 1 、 Figure 2 and Figure 6 , the liquid storage tank 22 is installed to the rear part of the cleaning robot main body 21. In addition, those skilled in the art can also set the liquid storage tank 22 at any other feasible position as needed, such as the front or middle part of the cleaning robot main body 21.

[0063] Furthermore, although not shown in the figure, the liquid storage tank 22 includes a liquid storage chamber and an electrical appliance installation chamber, wherein the liquid storage chamber is used to store clean cleaning liquid, and the electrical appliance installation chamber is at least equipped with a motor for driving the wiping member 23 to rotate.

[0064] Although not shown in the figures, the cleaning device is used to mop and wipe the surface to be cleaned, thereby cleaning the surface to be cleaned. The cleaning device includes a mopping member 23.

[0065] like Figure 6 As shown, the wiping member 23 is disposed on the lower side of the liquid storage tank 22 and is rotatably connected to the liquid storage tank 22. Furthermore, although not shown in the figures, a liquid supply hole is provided on the bottom wall of the liquid storage tank 22 at a position aligned with the wiping member 23. This allows the liquid storage chamber within the liquid storage tank 22 to drip cleaning liquid onto the wiping member 23 through the liquid supply hole, thereby providing cleaning liquid to the wiping member 23 during the wiping operation and keeping the wiping member 23 moist.

[0066] It should be noted that, although the wiping member 23 shown in the figure is a turntable-type wiping member, those skilled in the art may also set the turntable-type wiping member to a roller-type wiping member as required.

[0067] In addition, under the premise that the wiping member 23 can perform normal wiping operations, those skilled in the art may also omit the liquid storage tank 22 as needed and install the motor that drives the wiping member 23 to rotate on the cleaning robot body 21.

[0068] Although not shown in the figure, the dust collection system primarily includes a dust box and a dust collection fan located downstream of the dust box. The dust collection fan drives air flow to transfer dirt from beneath the cleaning robot 2 into the dust box. Furthermore, a roller brush is rotatably mounted on the cleaning robot body 21 to pick up dirt from beneath the cleaning robot 2. In other words, the rotating roller brush assists the dust collection fan in transferring dirt from beneath the cleaning robot 2 into the dust collection box.

[0069] Although not explicitly shown in the figure, the cleaning assembly includes a roller brush and a roller brush cover 24. Preferably, the cleaning assembly floats up and down relative to the cleaning robot body 21. Furthermore, the cleaning assembly includes a roller brush holder for mounting the roller brush. The roller brush holder is movably connected to the cleaning robot body 21 to enable the roller brush holder to float up and down relative to the cleaning robot body 21. Specifically, the front portion of the roller brush holder is pivotally connected to the cleaning robot body 21. Under the action of its own weight, the roller brush holder can float up and down in a swinging manner as the surface to be cleaned rises and falls.

[0070] like Figure 6 As shown, the roller brush cover 24 is detachably mounted on the cleaning robot body 21 , and the roller brush cover 24 is used to fix the roller brush to the cleaning robot body 21 to prevent the roller brush from falling from the cleaning robot body 21 .

[0071] like Figure 7 and Figure 8 As shown, the specific embodiment of the present disclosure provides two roller brush covers 24, which are specifically as follows.

[0072] like Figure 7 As shown, the first roller brush cover 24 of the present disclosure includes a suction port 241 that allows dirt to pass through, and a shielding portion 242 that contacts the surface to be cleaned. The shielding portion 242 is located behind the suction port 241 and is a flexible structure. The shielding portion 242 is used to prevent the roller brush from pushing dirt on the surface to be cleaned behind the suction port 241, and to prevent air behind the suction port 241 from entering the suction port 241. This allows air to enter the suction port 241 from the front, left, and right sides of the suction port 241, providing sufficient suction for the suction system to pick up the surface to be cleaned.

[0073] The shielding portion 242 is preferably made of an elastic material, and the elastic material may be rubber, silicone, elastic plastic, or any other feasible structure.

[0074] like Figure 8As shown, the second roller brush cover 24 of the present disclosure includes, in addition to the dust suction port 241 and the shielding portion 242, a fixed frame 243 and a cover body 244. The fixed frame 243 is detachably connected to the cleaning robot body 21, and the cover body 244 is connected to the fixed frame 243 and can float up and down relative to the fixed frame 243. Specifically, the cover body 244 is pivotally connected to the fixed frame 243 via its front end, so that the cover body 244 can swing up and down relative to the fixed frame 243 through this pivot connection, thereby achieving the purpose of floating up and down. Furthermore, the shielding portion 242 is fixedly connected to the fixed frame 243 via its top end and fixedly connected to the cover body 244 via its portion near the bottom end, so that the shielding portion 242 has an elastic portion 2421 located between the fixed frame 243 and the cover body 244. Under the action of this elastic portion 2421, the cover body 244 always has a downward force, forcing the bottom end of the shielding portion 242 to float up and down with the undulations of the surface to be cleaned. In other words, the elastic portion 2421 can ensure that the bottom end of the shielding portion 242 always contacts or is closest to the surface to be cleaned.

[0075] In addition, although not shown in the figures, those skilled in the art may also omit the elastic portion 2421 as needed and provide an elastic member between the fixing frame 243 and the cover 244. The elastic member can provide a downward force to the cover 244, so that the bottom end of the shielding portion 242 abuts against the abutting portion (sealing surface 123 or retaining rib 124) of the base station 1 or the surface to be cleaned.

[0076] Refer to the following Figure 9 and Figure 10 , to describe in detail the sealing contact process between the shielding portion 242 on the cleaning robot 2 and the base 12 of the base station 1.

[0077] like Figure 9 As shown, when the cleaning robot 2 walks on the base 12 and before the driving wheel 25 enters the positioning groove 121 , the shielding portion 242 on the cleaning robot 2 will not contact the sealing surface 123 .

[0078] like Figure 10 As shown, after the driving wheel 25 enters the positioning groove 121, the cleaning robot body 21 sinks, causing the shielding portion 242 to descend along with the cleaning robot body 21 to abut against the sealing surface 123. Preferably, the shielding portion 242 abutting against the sealing surface 123 is in a compressed state, so that the shielding portion 242 presses against the sealing surface 123 to ensure the reliability of the seal between the two.

[0079] In addition, those skilled in the art may also, as needed, use the retaining rib 124 instead of the sealing surface 123 as the abutment portion of the base station 1, so that after the driving wheel 25 enters the positioning groove 121, the shielding portion 242 also abuts against the retaining rib 124 on the rear side of the sealing surface 123, thereby achieving double sealing.

[0080] Those skilled in the art will appreciate that the present disclosure reduces the resistance of the cleaning robot 2 during its ascent by ensuring that the shielding portion 242 does not contact the guiding slope 122 or exerts very little pressure when the cleaning robot 2 ascends onto the base station 1 via the guiding slope 122. By ensuring that the shielding portion 242 sinks to a position of sealing contact with the sealing surface 123 when the cleaning robot 2 and the base station 1 are docked together, the seal between the shielding portion 123 and the base 12 can shield the dirty liquid thrown out by the wiping member 23, thereby preventing the dirty liquid from flowing into the dust suction port 241 and contaminating the dust suction port 241.

[0081] Refer to the following Figure 11 and Figure 12 , the sealing contact process between the cleaning robot 2 and the sealing portion 15 on the base station 1 is described in detail.

[0082] Before that, it should be noted that Figure 11 The distance L1 between the cleaning robot 2 and the height reference line 3 is greater than Figure 12 The distance L2 between the cleaning robot 2 and the height reference line 3.

[0083] like Figure 11 As shown, before the cleaning robot 2 walks on the base 12 and the driving wheel 25 enters the positioning groove 121, the cleaning robot 2 does not contact the sealing portion 15. As the cleaning robot 2 continues to move backward, the cleaning robot 2 begins to contact the sealing portion 15. At this time, the driving wheel 25 reaches the edge of the positioning groove 121; or has entered the positioning groove 121 but has not reached the deepest part of the positioning groove 121. As the cleaning robot 2 further moves backward, the driving wheel 25 enters the positioning groove 121 and gradually sinks, causing the cleaning robot body 21 to also begin to move backward and downward.

[0084] like Figure 12 As shown, when the driving wheel 25 rolls to the deepest part of the positioning groove 121, the cleaning robot body 21 moves backward and downward, so that the circumferential surface of the cleaning robot body 21 squeezes the sealing portion 15 backward and downward at the same time (as shown in FIG. Figure 12 That is, the sealing portion 15 has a downward flange when it is in contact with the circumferential surface of the cleaning robot body 21.

[0085] Those skilled in the art will appreciate that, by allowing the sealing portion 15 to enter the positioning groove 121 along with the driving wheel 25 of the cleaning robot 2, it is squeezed backward and downward by the circumferential surface of the cleaning robot main body 21, so that the sealing portion 15 has a downward flange when the cleaning robot 2 is docked with the base station 1. Compared with docking the sealing portion 15 with the cleaning robot 2 along the extension direction of the sealing portion, this avoids the situation where the sealing portion 15 is squeezed by the cleaning robot 2 to form wrinkles on its edge and cannot be sealed and docked with the circumferential surface of the cleaning robot 2.

[0086] When the sealing part 15 is in sealed contact with the circumferential surface of the cleaning robot 2, those skilled in the art will understand that the base station 1 and the cleaning robot 2 disclosed herein also prevent the cleaning liquid below the sealing part 15 in the cleaning tank 13 from splashing or evaporating above the sealing part 15, thereby corroding the charging terminal 16 on the base station 1 and the power receiving terminal on the cleaning robot 2.

[0087] It can be understood that the abutting portion can also be made of a flexible material and installed on the guide slope. When the cleaning robot is docked at the base station, the abutting portion abuts against the bottom of the cleaning robot.

[0088] Thus far, the technical solutions of the present disclosure have been described in conjunction with the foregoing multiple embodiments. However, it is easy for those skilled in the art to understand that the scope of protection of the present disclosure is not limited to these specific embodiments. Without departing from the technical principles of the present disclosure, those skilled in the art may split and combine the technical solutions in the above-mentioned various embodiments, and may also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concepts and / or technical principles of the present disclosure will fall within the scope of protection of the present disclosure.
