Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning device. Background Technology

[0002] Robotic vacuum cleaners, mops, and floor scrubbers are types of smart home appliances that can automatically clean floors in a room using a certain level of artificial intelligence. However, due to the complexity of the work environment, such as thresholds between the balcony and the living room, or between the living room and the bathroom, these cleaning devices may get stuck due to insufficient obstacle-crossing ability, thus failing to continue cleaning.

[0003] Currently, cleaning equipment typically uses a separate drive mechanism on its wheels to lift the base, allowing it to traverse obstacles. Simultaneously, another separate drive mechanism on the base directs water from the clean water tank to the mop, wetting it. This solution requires two separate drive mechanisms for lifting the base and wetting the mop, increasing the cost of the cleaning equipment. Utility Model Content

[0025] The piston is connected to the rolling component via a connecting component, and the rolling component floats relative to the cylinder body in a direction perpendicular to the height of the bottom shell.

[0026] Furthermore, the rolling component includes:

[0027] A bracket is rotatably connected to the adapter via a pivot, and under the drive of the cylinder, the bottom shell is raised or lowered along its height direction.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0061] See Figures 1 to 20 As shown, this application provides a cleaning device. The cleaning device includes a base shell 10, a rolling component 20, and an air pump component 30. A clean water tank 11 and an air cylinder 12 are disposed on the base shell 10. The rolling component 20 is disposed on the base shell 10 and, driven by the air cylinder 12, moves along the height direction of the base shell 10 (e.g., ...). Figure 1 (In the direction indicated by the middle arrow X) Raise or lower the bottom shell 10. An air pump component 30 is disposed on the bottom shell 10. The air pump component 30 has a first state for pressurizing the clean water tank 11 to discharge the water in the clean water tank 11. The air pump component 30 also has a second state for pressurizing the cylinder 12 to raise the bottom shell 10 by the rolling component 20.

[0062] In this embodiment, during cleaning operations, the rolling component 20 rests against the ground, and the air pump component 30 pressurizes the cylinder 12, causing the bottom shell 10 to move away from the rolling component 20 along the X direction. This increases the distance between the bottom shell 10 and the cleaning surface, allowing the bottom shell 10 to smoothly overcome obstacles. Simultaneously, the air pump component 30 can also pressurize the clean water tank 11 to drain the water. In other words, this cleaning setup only requires one air pump component 30 to simultaneously pressurize and drain the clean water tank 11 and drive the rolling component 20 to lift the bottom shell 10. This significantly reduces the number of components and manufacturing costs within the cleaning equipment, simplifies the cleaning equipment and production assembly process, and improves the assembly efficiency and production cycle of the cleaning equipment. Compared to existing technologies, this embodiment eliminates the need for independent installation space for two drive structures, saving internal space in the bottom shell 10 and facilitating the miniaturization and thinning of cleaning equipment.

[0063] The bottom of the base shell 10 is equipped with a cleaning component. The air pump component 30 pressurizes the water tank 11, causing the water in the water tank 11 to flow out onto the cleaning component under pressure and wet the cleaning component, thereby enabling the cleaning component to perform wet cleaning on the cleaning surface. Specifically, the cleaning component in this embodiment includes a disc mop 13, on which the water in the water tank 11 flows to wet the disc mop 13.

[0064] When the air pump component 30 is in the second state, it pressurizes the cylinder 12. The cylinder 12 drives the base shell 10 to move away from the rolling component 20 along the X direction, increasing the distance between the base shell 10 and the rolling component 20. This ensures that the base shell 10 can smoothly pass over obstacles, reducing collision and wear between the cleaning equipment and obstacles, making the cleaning equipment suitable for complex environments. After the cleaning equipment passes over the obstacle, the cylinder 12 drives the base shell 10 to move closer to the rolling component 20, causing the base shell 10 to return to its original position.

[0065] like Figures 1 to 2 As shown, the rolling component 20 further includes a drive wheel assembly 21 and an auxiliary wheel assembly 22. The drive wheel assembly 21 is disposed on the bottom shell 10. The auxiliary wheel assembly 22 is disposed on the bottom shell 10. The drive wheel assembly 21 rolls under the action of the drive motor, and is responsible for the power output and steering of the cleaning equipment. The auxiliary wheel assembly 22 mainly plays a supporting and balancing role. In this embodiment, the drive wheel assembly 21 includes a first drive wheel 211 and a second drive wheel 212, which are spaced apart. The auxiliary wheel assembly 22 includes a universal wheel 221, which is disposed on the center line between the first drive wheel 211 and the second drive wheel 212. At least three cylinders 12 are provided, and the at least three cylinders 12 are respectively disposed in one-to-one correspondence with the first drive wheel 211, the second drive wheel 212 and the universal wheel 221. The first drive wheel 211 and the second drive wheel 212 are respectively driven by the corresponding cylinder 12 to raise or lower the bottom shell 10 along its height direction. That is, the air pump component 30 can drive only the first drive wheel 211 to raise or lower the bottom shell 10. The air pump component 30 can also drive only the second drive wheel 212 to raise or lower the bottom shell 10. The air pump component 30 can also drive the first drive wheel 211 and the second drive wheel 212 to raise or lower the bottom shell 10 simultaneously. During the cleaning process, the cleaning equipment can adjust the distance between the bottom shell 10 and the first drive wheel 211 and the second drive wheel 212 according to the position and height of the obstacle, thereby adjusting the tilt and lifting posture of the bottom shell 10.

[0066] In some embodiments, the auxiliary wheel assembly 22, driven by the cylinder 12, raises or lowers the base shell 10 along its height direction. In other embodiments, both the drive wheel assembly 21 and the auxiliary wheel assembly 22, driven by the cylinder 12, raise or lower the base shell 10 along its height direction. For example, when encountering a high threshold, both the drive wheel assembly 21 and the auxiliary wheel assembly 22 need to raise the base shell 10 simultaneously to ensure that the base shell 10 can be crossed, reducing friction between the base shell 10 and the threshold. If the obstacle is located on the side of the auxiliary wheel assembly, only the auxiliary wheel assembly 22 needs to raise the base shell 10, which can improve the obstacle-crossing efficiency of the cleaning equipment and reduce energy consumption, helping to extend the endurance of the cleaning equipment and improve its flexibility.

[0067] Furthermore, such as Figure 3 , Figures 10 to 17 As shown, cylinder 12 includes cylinder body 121 and piston 122. Cylinder body 121 is connected to bottom shell 10 by fasteners 123 such as screws. Piston 122 reciprocates within cylinder body 121 along the height direction of bottom shell 10. Piston 122 is connected to rolling member 20 via adapter 14, and moves along a direction perpendicular to the height direction of bottom shell 10 (e.g., ...). Figure 1 (In the direction indicated by the middle arrow Y), the rolling component 20 floats relative to the cylinder 121. The piston 122 is disposed inside the cylinder 121 and forms a sealed cavity 124 with the inner wall of the cylinder 121. When the air pump component 30 inflates the sealed cavity 124, the piston 122 moves within the cylinder 121 under pressure, and the piston 122 drives the rolling component 20 to move relative to the bottom shell 10 through the adapter component 14, thereby increasing the distance between the bottom shell 10 and the rolling component 20 to lift the bottom shell 10. In addition, due to uneven ground or obstacles encountered by the rolling component 20, the rolling component 20 may deviate from the piston 122 in the Y direction, causing the rolling component 20 to exert a force on the piston 122 in the Y direction, resulting in the failure of the seal of the sealed cavity 124. To ensure good sealing of the sealing cavity 124, the rolling component 20 in this embodiment can float relative to the cylinder body 121, that is, the rolling component 20 can float relative to the piston 122. This reduces the Y-direction force transmitted from the rolling component 20 to the piston 122, ensuring stable sealing performance between the cylinder body 121 and the piston 122, and preventing gas leakage from affecting the driving accuracy and efficiency of the cylinder 12. Meanwhile, during assembly, strict component control is required for both the rolling component 20 and the piston 122 to ensure good sealing of the sealing cavity 124. This embodiment, by setting the rolling component 20 to float relative to the cylinder body 121, ensures that the rolling component 20 and the piston 122 can maintain good sealing of the sealing cavity 124 even without strict component control.

[0068] In some embodiments, such as Figures 13 to 20As shown, the adapter component 14 includes a connector 141 and an adapter frame 142. The connector 141 is fixedly connected to the piston 122. The adapter frame 142 is fixedly connected to the rolling component 20. A first groove 143 is provided at the top of the adapter frame 142, and at least a portion of the connector 141 is located within the first groove 143 and has a gap with the side wall of the first groove 143. When the rolling component 20 deviates in the Y direction, the adapter frame 142 and the rolling component 20 can move slightly relative to the connector 141, reducing the force in the Y direction on the piston 122, thereby ensuring that the piston 122 is tightly fitted to the inner wall of the cylinder 121 and ensuring the stable sealing of the sealing cavity 124.

[0069] The adapter frame 142 includes a limiting part 1421 and a guide part 1422. A first groove 143 is disposed within the limiting part 1421. The cylinder body 121 is sleeved on the outside of the limiting part 1421 and moves relative to the limiting part 1421 along the height direction of the bottom shell 10. A second groove 1424 is disposed within the guide part 1422. The limiting part 1421 is located within the second groove 1424 and is arranged with a gap between it and the inner sidewall of the second groove 1424. When the rolling component 20 lowers the bottom shell 10, the cylinder body 121 extends at least partially into the gap between the limiting part 1421 and the inner sidewall of the second groove 1424. During the process of the rolling component 20 lifting and lowering the bottom shell 10, the cylinder body 121 moves along the outer sidewall of the limiting part 1421. The limiting part 1421 can provide guidance for the movement of the cylinder body 121, effectively preventing the cylinder body 121 from shifting and thus affecting the sealing performance of the sealing cavity 124. The second groove 1424 is used to avoid the cylinder body 121. At the same time, the gap between the second groove 1424 and the limiting part 1421 can also limit and guide the cylinder body 121. In addition, the second groove 1424 also provides sufficient floating space for the adapter 142 to float relative to the piston 122 in the Y direction.

[0070] In another embodiment, the connector 141 is provided with a first groove 143, and the adapter 142 is at least partially located in the first groove 143 and has a gap between it and the side wall of the first groove 143.

[0071] In some embodiments, a mounting hole 15 is provided through the bottom shell 10 along its height direction. The adapter frame 142 is mounted in the mounting hole 15 and can reciprocate relative to the bottom shell 10 along its height direction. A support portion 151 protrudes from the inner wall of the mounting hole 15. The adapter frame 142 has a stop portion 1423 located at the top of the support portion 151, and an elastic reset member 152 is provided between the stop portion 1423 and the support portion 151. When the cleaning equipment encounters an obstacle, the rolling component 20 abuts against the ground, the rolling component 20 and the adapter frame 142 remain stationary relative to the ground, the air pump component 30 inflates the sealing cavity 124, and the cylinder 121 drives the bottom shell 10 to rise relative to the ground to increase the distance between the bottom shell 10 and the ground, thereby ensuring that the cleaning equipment can smoothly overcome the obstacle. During the process of the bottom shell 10 being raised relative to the ground, the support part 151 gradually approaches the stop part 1423 and squeezes the elastic reset member 152, causing the elastic reset member 152 to be in a contracted state.

[0072] Once the cleaning equipment has passed the obstacle, the air pump component 30 stops pumping air into the sealed cavity 124, and the cylinder 121 stops rising relative to the ground. Under the weight of the bottom shell 10 and the cylinder 121, the bottom shell 10 and the cylinder 121 tend to descend relative to the ground, and the support portion 151 also tends to move away from the stop portion 1423. At this time, the elastic reset member 152 extends, causing the support portion 151 to move relative to the stop portion, and driving the bottom shell 10 to move closer to the ground, thus resetting the bottom shell 10.

[0073] Furthermore, the stop portion 1423 can also limit the continuous upward movement of the support portion 151, thereby limiting the lifting range of the bottom shell 10 and preventing the cylinder body 121 from being excessively lifted and separating from the piston 122. The elastic reset member 152 can provide an automatic reset driving force for the adapter frame 142 after the driving force of the cylinder 12 disappears, helping the bottom shell 10 to quickly lower and reset, ensuring that the cleaning equipment returns to normal cleaning state.

[0074] In this embodiment, the elastic reset member 152 can be configured as a spring. Optionally, the elastic reset member 152 in this embodiment can also be configured as an elastic pad, elastic rubber, etc. This application does not make specific limitations. As long as the deformation mode is to contract under the action of external force and can be restored and extended after the external force is removed, it is within the protection scope of this application.

[0075] Specifically, along the Y direction, the limiting portion 1421 at least partially protrudes from the guide portion 1422 and is disposed opposite to the support portion 151. The bottom of the limiting portion 1421 is a stop portion 1423, and the elastic reset member 152 abuts against the bottom of the limiting portion 1421 and the support portion 151. A mounting member 150 is disposed in the mounting hole 15, and an adapter is disposed through the mounting member 150. The support portion 151 is disposed in the mounting member 150. The adapter member 14 is mounted to the bottom shell 10 via the mounting member 150.

[0076] Furthermore, the rolling component 20 includes a bracket 23 and a roller 24. The bracket 23 is rotatably connected to the adapter 14 via a pivot 234, and, driven by the cylinder 12, raises or lowers the bottom shell 10 along its height direction. The roller 24 is rotatably connected to the bracket 23. The bracket 23 rotates around the pivot 234, allowing the roller 24 to more flexibly adapt to undulations, inclinations, or obstacles on the ground, reducing excessive localized stress caused by uneven ground. When the bracket 23, in conjunction with the cylinder 12, raises or lowers the bottom shell 10, the contact angle between the roller 24 and the ground can be finely adjusted by the rotation of the bracket 23, improving the mobility of the cleaning equipment in complex terrain. Meanwhile, the rolling connection between the roller 24 and the bracket 23 reduces the frictional resistance when the cleaning equipment moves, making the cleaning process smoother and reducing energy consumption. The rotating connection between the bracket 23 and the adapter 14 can also work in conjunction with the floating structure and elastic reset component 152 of the adapter 14 to further buffer the impact force of the cleaning equipment in the Y direction and other directions, reducing the impact of external forces on the sealing system of the cylinder 12.

[0077] Specifically, the bracket 23 includes a bracket body 231, a rotating sleeve 232, and a rolling shaft 233. Along the Y direction, the rolling shaft 233 passes through the roller 24, and both ends of the rolling shaft 233 extend out of the roller 24 and are rotatably connected to the bracket body 231. The top of the bracket body 231 is connected to the rotating sleeve 232. The end of the rotating sleeve 232 is inserted into the bottom end of the guide portion 1422 and sleeved onto the rotating shaft 234. The rotating shaft 234 is rotatably connected to the rotating sleeve 232. The end of the rotating shaft 234 away from the guide portion 1422 extends into the bracket body 231 and is rotatably connected to the bracket body 231.

[0078] In some embodiments, such as Figures 3 to 9 As shown, the air pump component 30 includes a pump body 301, a first pipe 302, and a second pipe 303. The pump body 301 is provided with a first exhaust port 31 and a second exhaust port 32. The first pipe 302 connects the first exhaust port 31 to the cylinder 12. The second pipe 303 connects the second exhaust port 32 to the clean water tank 11. Gas from the pump body 301 flows into the first pipe 302 and then into the cylinder 12, allowing the base shell 10 to be raised relative to the ground to overcome obstacles. Gas from the pump body 301 flows into the second pipe 303 and then into the clean water tank 11, causing water in the clean water tank 11 to be discharged onto the cleaning component.

[0079] Further, the pump body 301 includes a pump body 3011 and a gas diversion component 3013. The pump body 3011 is provided with an outlet 3012. A first exhaust port 31 and a second exhaust port 32 are both located on the gas diversion component 3013. The gas diversion component 3013 also includes a gas inlet 3014. The first exhaust port 31 and the second exhaust port 32 are respectively connected to the gas inlet 3014, which is connected to the outlet 3012. In this embodiment, the gas diversion component 3013 has a three-way structure. When the base shell 10 is raised, the gas inside the pump body 3011 flows out from the outlet 3012 and sequentially flows through the gas inlet 3014, the first exhaust port 31, and the first pipeline 302 before entering the cylinder 12. When the clean water tank 11 supplies water to the cleaning component, the gas in the air pump body 3011 flows out from the air outlet 3012 and flows sequentially through the gas inlet 3014, the second exhaust port 32, and the second pipeline 303 before entering the cylinder 12. The gas diverter 3013 can divide the gas in the air pump body 3011 into at least two paths.

[0080] A first solenoid valve 33 is installed on the first pipeline 302, which controls the opening and closing of the first pipeline 302. The first solenoid valve 33 can precisely control the opening and closing of the first pipeline 302, thereby controlling whether to charge the cylinder 12. When it is necessary to lift the base shell 10, the first solenoid valve 33 is opened, allowing the air pump body 3011 to supply air to the cylinder 12, and the cylinder body 121 drives the base shell 10 to lift. In addition, by accurately controlling the air pressure in the cylinder 12, the lifting height of the base shell 10 can be accurately controlled to adapt to obstacles of different heights, enabling precise obstacle-crossing maneuvers.

[0081] Specifically, the cylinder body 121 is provided with a connecting port 1211, which is connected to the sealing cavity 124, and the gas enters the sealing cavity 124 through the connecting port 1211.

[0082] A second solenoid valve 36 is installed on the second pipeline 303, which controls the opening and closing of the second pipeline 303. The second solenoid valve 36 can precisely control the opening and closing of the second pipeline 303, thereby controlling whether to pressurize the water tank 11 and thus controlling the water supply to the cleaning components. When the water tank 11 is being pressurized, the second solenoid valve 36 controls the second pipeline 303 to open, and the gas in the air pump body 3011 enters the water tank 11 through the second pipeline 303.

[0083] Furthermore, the first solenoid valve 33 is provided with a first connecting channel 331, which connects the first exhaust port 31 and the cylinder 12. When the base shell 10 needs to be raised, the gas in the air pump body 3011 flows into the first connecting channel 331 and then into the cylinder 12 through the first pipe 302. The first connecting channel 331 is provided with a first venting channel 332, which connects the first connecting channel 331 and the outside of the pump body 301. When the base shell 10 is reset, the gas in the cylinder 12 flows into the first pipe 302 and enters the first connecting channel 331, and then is discharged into the atmosphere through the first venting channel 332.

[0084] The second solenoid valve 36 is provided with a second connecting channel 361, which connects the second exhaust port 32 and the clean water tank 11. When pressurization is required in the clean water tank 11, the gas in the air pump body 3011 flows into the second connecting channel 361 and then into the clean water tank 11 through the second pipeline 303. The second connecting channel 361 is provided with a second venting channel 362, which connects the second connecting channel 361 and the outside of the pump body 301. When water is added to the clean water tank 11, excess gas in the clean water tank 11 can flow into the second pipeline 303 and enter the second connecting channel 361, and then be discharged into the atmosphere through the second venting channel 362.

[0085] In addition, the independent first pipeline 302 and second pipeline 303 ensure that the air supply path for pressurizing the clean water tank 11 and the air supply path for pressurizing the cylinder 12 of the air pump component 30 are clearly distinguished and independently controlled, ensuring that the lifting of the bottom shell 10 and the wetting of the cleaning components do not interfere with each other, thereby improving the stability and reliability of the cleaning equipment operation.

[0086] Optionally, the first exhaust port 31 is directly connected to the first solenoid valve 33, and the second exhaust port 32 is connected to the second solenoid valve 36 through the connecting pipe 320.

[0087] In some embodiments, a pressurization port is provided through the top of the clean water tank 11. The pressurization port is connected to the second pipeline 303. Gas from the air pump component 30 flows through the second pipeline 303 and the pressurization port into the clean water tank 11. The pressurization port at the top allows the gas input from the air pump component 30 to act more evenly on the water surface in the clean water tank 11, avoiding excessively high or insufficient local air pressure due to improper pressurization position, ensuring precise control of drainage volume, and thus stabilizing the wetting degree of the mop. The pressurization port at the top facilitates a tight connection with the second pipeline 303, reducing gas leakage points, improving air pressure utilization efficiency, and ensuring the stability of the air circuit. In addition, the pressurization port at the top simplifies the assembly process of the clean water tank 11 and the second pipeline 303, facilitating later maintenance and repair.

[0088] In some embodiments, a water supply port is provided through the bottom of the clean water tank 11, and the water supply port is connected to a water supply pipe. The water supply pipe extends a predetermined distance along the height direction of the bottom shell 10, and the predetermined distance is greater than the maximum distance between the liquid level in the clean water tank 11 and the bottom wall of the clean water tank 11. The water supply pipe is used to supply water to the cleaning components of the cleaning equipment. Utilizing the principle of liquid communication, when no water is supplied to the cleaning components, some water in the clean water tank 11 will flow into the water supply pipe, and the liquid level in the water supply pipe will be the same as the liquid level in the clean water tank 11. The portion of the water supply pipe above the liquid level forms a liquid seal, which can prevent water from flowing out on its own when the clean water tank 11 is not pressurized, preventing water leakage from the cleaning equipment, reducing water waste and secondary pollution of the ground. At the same time, when the air pump component 30 pressurizes the clean water tank 11 through the pressurization port, the air pressure can overcome the resistance formed by the height difference, allowing water to flow smoothly out along the water supply pipe. With precise control of the air pressure, stable control of the water supply can be achieved, ensuring that the mop is wetted to meet cleaning requirements. In addition, the water inlet at the bottom makes it easy to drain the water in the clean water tank 11 as much as possible, reducing residual water accumulation. The height design of the water supply pipe can achieve basic water-stopping function without the need for additional sealing valves, which simplifies the structure and reduces the risk of failure, further improving the practicality and reliability of the cleaning equipment.

[0089] Specifically, along the extension direction of the water supply pipe, the end of the water supply pipe away from the clean water tank 11 extends to the vicinity of the cleaning component. The water supply pipe is used at least to supply water to the cleaning component of the cleaning equipment to wet the cleaning component and ensure that the cleaning component can perform wet cleaning work more efficiently.

[0090] In some embodiments, a heating module 16 is provided on the base shell 10. The air pump component 30 also includes an air inlet channel 39 that extends to the heating module 16 to at least draw out the heat released by the heating module 16. During operation, the air pump component 30 can carry the heat generated by the heating module 16 into the air system along with the drawn-in gas. When the gas enters the clean water tank 11 or the cylinder 12, the heat can preheat the water in the clean water tank 11, raising the water temperature to enhance the cleaning effect of the mop, or heat the gas in the cylinder 12, utilizing the principle of thermal expansion and contraction to improve the air pressure drive efficiency, making the lifting action of the base shell 10 more rapid. Simultaneously, actively drawing out heat can effectively reduce the temperature around the heating module 16, preventing component aging or performance degradation due to heat accumulation inside the cleaning equipment, thus extending its service life. Furthermore, this cleaning equipment reduces energy waste and optimizes the energy efficiency and environmental friendliness of the cleaning equipment.

[0091] Specifically, the heating module 16 includes a mounting shell and a heating unit. The mounting shell contains a mounting cavity, and the heating unit is disposed within the mounting cavity. An air inlet and an air outlet are provided on the side wall of the mounting cavity. The air inlet connects the outside of the mounting shell to the mounting cavity, and the air outlet connects the mounting cavity to the air intake channel 39. The heating unit includes a battery unit, which is disposed within the mounting shell. The air intake channel 39 of the air pump component 30 is connected to the air outlet of the mounting shell. Gas enters the mounting shell from the air inlet and flows through the battery unit to carry away some of the heat generated by the battery unit. Then, the hot air is drawn into the air pump component 30 through the air outlet and the air intake channel 39.

[0092] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0093] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0094] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
