Description

Technical Field

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

[0002] Most cleaning equipment on the market is equipped with anti-slip tires. Anti-slip tires have grooves on their outer circumference, which increases the coefficient of sliding friction and allows the tire to move stably on wet ground.

[0003] However, during the cleaning process, debris can easily get stuck in the grooves of the tires. Utility Model Content

[0004] The main objective of this application is to provide a tire and a cleaning device to at least solve the problem in the prior art that garbage easily gets stuck in the grooves of the tire.

[0005] According to one aspect of this application, a tire is provided, comprising:

[0006] The main body has at least one of an annular groove and a first groove on its outer peripheral surface. The annular groove extends along the circumferential direction of the main body, and the first groove extends in a direction parallel to the axis of the main body, or the projection of the extension direction of the first groove in the radial direction of the main body intersects the axis of the main body.

[0007] The ratio of the maximum width L1 of the annular groove to the maximum width L of the main body along the axial direction, and the ratio of the maximum width L2 of the first groove to the maximum width L of the main body along the axial direction, at least one of them satisfies the following relationship: 0.012≤L1 / L≤0.060, 0.012≤L2 / L≤0.060, wherein at least one of L1 and L2 satisfies the following relationship: 0.3mm≤L1≤0.6mm, 0.3mm≤L2≤0.6mm.

[0008] Furthermore, the body has a first surface and a second surface disposed opposite to each other along the axial direction of the body, and the first groove includes a plurality of first grooves, which are spaced apart along the circumferential direction of the body;

[0009] The annular groove includes one portion of the first groove extending along the annular groove to the first surface, and the remaining portion extending along the annular groove to the second surface; or...

[0010] The annular groove includes a plurality of annular grooves, which are spaced apart along the axial direction of the body. Some of the first grooves are connected between two adjacent annular grooves, some of the first grooves are connected between the first surface and the annular groove closest to the first surface along the axial direction of the body, and the remaining first grooves are connected between the second surface and the annular groove closest to the second surface along the axial direction of the body.

[0011] Furthermore, the annular groove includes one, the midpoint of the annular groove is collinear with the midpoint of the outer peripheral surface of the main body, and multiple first grooves are provided on both sides of the annular groove along the circumferential direction of the main body, and the first grooves extend along the axial direction of the main body.

[0012] Wherein, the length A of the first groove along the circumferential direction of the main body and the maximum width L1 of the main body satisfy the following relationship: 0.470≤A / L≤0.494.

[0013] Furthermore, the maximum depth D1 of the annular groove is greater than or equal to the maximum depth D2 of the first groove.

[0014] Furthermore, the maximum depth D1 of the annular groove and the maximum depth D2 of the first groove satisfy the relationship: 0.25≤D2 / D1≤1.00.

[0015] Furthermore, the maximum depth D1 of the annular groove satisfies the relationship: 0.5mm ≤ D1 ≤ 2.0mm; and / or,

[0016] The maximum depth D2 of the first groove satisfies the following relationship: 0.5mm≤D2≤1.5mm.

[0017] Furthermore, the maximum depth D1 of the annular groove and the maximum width L1 of the annular groove satisfy the following relationship: 0.15 ≤ L1 / D1 ≤ 1.2; and / or,

[0018] The maximum depth D2 of the first groove and the maximum width L2 of the first groove satisfy the following relationship: 0.6≤L2 / D2≤1.2.

[0019] Furthermore, the maximum depth D1 of the annular groove, the maximum width L1 of the annular groove, the maximum depth D2 of the first groove, and the maximum width L2 of the first groove satisfy the following relationship: 0.171 ≤

[0020] (L1+L2) / (D1+D2)≤1.200.

[0021] Furthermore, the first groove has a first edge and a second edge located on the outer peripheral surface and disposed opposite to each other, and at least one of the first edge and the second edge is provided with a rounded corner;

[0022] The radius R of the fillet satisfies the following relationship: R≥0.2mm.

[0023] On the other hand, this application also provides a cleaning device, which includes the aforementioned tire.

[0024] Compared to existing technologies, this application defines the maximum width of the annular groove or the first groove. Specifically, at least one of the following relationships must satisfy the following: the ratio of the maximum width L1 of the annular groove to the maximum width L of the main body along its axial direction; and the ratio of the maximum width L2 of the first groove to the maximum width L of the main body along its axial direction: 0.012 ≤ L1 / L ≤ 0.060, 0.012 ≤ L2 / L ≤ 0.060. When the ratio of L1 to L satisfies the above relationship, the maximum width of the annular groove is neither too small nor too large relative to the maximum width of the main body. This allows the annular groove to improve tire anti-skid capability while, to a certain extent, preventing excessive debris from accumulating within it. Similarly, when the ratio of L2 to L satisfies the above relationship, the first groove can improve tire anti-skid capability while also preventing excessive debris from accumulating within it. Furthermore, compared to existing technologies, this application also limits the value range of L2 and L1, specifically, L1 satisfies the relationship: 0.3mm ≤ L1 ≤ 0.6mm. When L1 satisfies the above relationship, the maximum width of the annular groove is set appropriately, which can improve the tire's anti-skid ability to a certain extent and prevent excessive debris with a diameter between 0.05mm and 8mm from getting stuck in the annular groove. Similarly, when the maximum width L2 of the first groove satisfies the relationship: 0.3mm ≤ L2 ≤ 0.6mm, the maximum width of the first groove will not be too narrow, increasing the contact area between the tire and the clean surface. Conversely, the maximum width of the first groove will not be too large, making it easier for debris with a diameter between 0.05mm and 8mm to get stuck in the first groove. In this application, the values ​​of L1 / L and L2 / L can be 0.012, 0.020, 0.025, 0.030, 0.035, 0.040, 0.045, 0.050, 0.055, and 0.060. The values ​​of L1 and L2 can be 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, and 0.6mm. Attached Figure Description

[0041] See Figures 1 to 10 As shown, according to an embodiment of this application, a cleaning device is provided, the cleaning device including a tire, wherein the tire includes a body 10.

[0042] The outer circumferential surface of the main body 10 is provided with at least one of an annular groove 11 and a first groove 12. The annular groove 11 extends along the circumferential direction of the main body 10, and the first groove 12 extends in a direction parallel to the axis of the main body 10, or the projection of the extension direction of the first groove 12 in the radial direction of the main body 10 intersects the axis of the main body 10. At least one of the ratios of the maximum width L1 of the annular groove 11 to the maximum width L of the main body 10 along the axial direction and the ratio of the maximum width L2 of the first groove 12 to the maximum width L of the main body 10 satisfies the following relationship: 0.012≤L2 / L≤0.060, 0.012≤L1 / L≤0.060, wherein at least one of L1 and L2 satisfies the following relationship: 0.3mm≤L1≤0.6mm, 0.3mm≤L2≤0.6mm.

[0043] Specifically, after at least one of the annular groove 11 and the first groove 12 is formed on the outer peripheral surface of the main body 10, the contact area between the tire and the ground is increased due to the groove, thereby increasing the sliding friction of the tire and preventing the tire from slipping during cleaning. In some embodiments, the annular groove 11 is formed on the main body 10, and the annular groove 11 extends along the circumferential direction of the main body 10. In this embodiment, the annular groove 11 not only improves the tire's anti-slip ability but also has a certain drainage function, thereby preventing the formation of a water film on the outer peripheral surface of the tire when running on a wet surface, which would reduce the tire's anti-slip ability. In other embodiments, the first groove 12 is formed on the outer peripheral surface of the main body 10, as shown in the attached figure. Figure 1 Or attached Figure 6 As shown, the extending direction of the first groove 12 can be the same as the axial direction of the main body 10, as illustrated in the attached figure. Figure 5 As shown, the projection of the extension direction of the first groove 12 onto the radial direction of the main body 10 can also intersect with the axial direction of the main body 10. Of course, in some embodiments, the first groove 12 and the annular groove 11 can be simultaneously provided on the outer peripheral surface of the main body 10 to further improve the tire's anti-slip capability. It is understood that cleaning equipment includes robotic vacuum cleaners, multi-functional cleaning base stations, and vacuum cleaners. These cleaning devices are commonly used in homes. Common household waste, such as rice, millet, fine sand, and mung beans, has a diameter of approximately 0.05mm to 8mm. When the maximum width of the first groove 12 or the annular groove 11 is too large, this waste can easily get stuck in the first groove 12 or the annular groove 11, leading to time-consuming and laborious maintenance and cleaning of the cleaning equipment.

[0044] Compared to existing technologies, this embodiment limits the maximum width of the annular groove 11 or the first groove 12. Specifically, at least one of the following relationships must satisfy the following: the ratio of the maximum width L1 of the annular groove 11 to the maximum width L of the main body 10 along its axial direction; and the ratio of the maximum width L2 of the first groove 12 to the maximum width L of the main body 10 along its axial direction: 0.012 ≤ L1 / L ≤ 0.060, 0.012 ≤ L2 / L ≤ 0.060. When the ratio of L1 to L satisfies the above relationship, the maximum width of the annular groove 11 is neither too small nor too large relative to the maximum width of the main body 10. This allows the annular groove 11 to improve tire anti-skid capability while, to a certain extent, preventing excessive debris from accumulating within it. Similarly, when the ratio of L2 to L satisfies the above relationship, the first groove 12 can improve tire anti-skid capability while also preventing excessive debris from accumulating within it. Furthermore, compared to existing technologies, this embodiment also limits the value range of L2 and L1, that is, L1 satisfies the relationship: 0.3mm≤L1≤0.6mm. When L1 satisfies the above relationship, the maximum width of the annular groove 11 is set appropriately, which can improve the anti-skid ability of the tire to a certain extent, and can prevent too many debris with a diameter between 0.05mm and 8mm from getting stuck in the annular groove 11. Similarly, when the maximum width L2 of the first groove 12 satisfies the relationship: 0.3mm≤L2≤0.6mm, the maximum width of the first groove 12 will not be too narrow, so that the contact area of ​​the tire when in contact with the clean surface is increased. The maximum width of the first groove 12 will not be too large, so that debris with a diameter between 0.05mm and 8mm is easily stuck in the first groove 12. In this embodiment, the values ​​of L1 / L and L2 / L can be 0.012, 0.020, 0.025, 0.030, 0.035, 0.040, 0.045, 0.050, 0.055, and 0.060. The values ​​of L1 and L2 can be 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, and 0.6mm.

[0045] Further, the body 10 has a first surface 101 and a second surface 102 disposed opposite to each other along the axial direction of the body 10, and the first groove 12 includes a plurality of first grooves 12, which are spaced apart along the circumferential direction of the body 10. In some embodiments, as shown in the attached figure Figure 3 As shown, the annular groove 11 includes one, a portion of the first groove 12 extends along the annular groove 11 to the first surface 101, and the remaining first groove 12 extends along the annular groove 11 to the second surface 102.

[0046] In this embodiment, the annular groove 11 is connected to a plurality of first grooves 12, and a portion of the first grooves 12 extends to the first surface 101 and a portion of the first grooves 12 extends to the second surface 102. When the cleaning equipment cleans on a wet and slippery surface, water stains on the tires can enter the annular groove 11 and drain the water from the first grooves 12. In addition, when there is garbage in the annular groove 11 and the first grooves 12, some of the garbage in the annular groove 11 and the first grooves 12 can be carried out by the water stains while draining the water.

[0047] In other embodiments, as shown in the appendix Figure 6 As shown, the annular groove 11 includes multiple annular grooves 11, which are spaced apart along the axial direction of the main body 10. Some first grooves 12 are connected between two adjacent annular grooves 11, some first grooves 12 are connected between the first surface 101 and the annular groove 11 that is closest to the first surface 101 along the axial direction of the main body 10, and the remaining first grooves 12 are connected between the second surface 102 and the annular groove 11 that is closest to the second surface 102 along the axial direction of the main body 10.

[0048] Specifically, the arrangement of multiple annular grooves 11 further enhances the tire's anti-skid and drainage capabilities. Furthermore, some of the first grooves 12 connect between adjacent annular grooves 11, facilitating the guidance of water stains between adjacent annular grooves 11 into the annular grooves 11, ultimately draining the water stains through the first groove 12 connected to the first surface 101 or the second surface 102. Similarly, during drainage, debris within the first grooves 12 and annular grooves 11 may also be expelled from the tire by the water flow.

[0049] In one specific embodiment, as shown in the appendix Figure 3 As shown, the annular groove 11 includes one, and the midline of the annular groove 11 (as shown in the attached figure) Figure 3 As shown in K), the annular groove 11 is collinear with the midline of the outer peripheral surface of the main body 10. Multiple first grooves 12 are provided on both sides of the annular groove 11 along the circumferential direction of the main body 10, and the first grooves 12 extend along the axial direction of the main body 10. The length A of the first groove 12 along the circumferential direction of the main body 10 and the maximum width L of the main body 10 satisfy the following relationship: 0.470≤A / L≤0.494.

[0050] It is understandable that the longer the length A of the first groove 12 along the axis of the main body 10, the easier it is for trash to get stuck in the first groove 12. Since the first groove 12 is connected to the annular groove 11 and extends to the first surface 101 or the second surface 102, if the length A of the first groove 12 is set too short, the maximum width of the annular groove 11 will be too large, making it easy for larger trash to get stuck in the annular groove 11. In fact, when the maximum width of the first groove 12 is set too small, larger trash is difficult to enter the first groove 12, and smaller trash stuck in the first groove 12 is easily carried out when the tire moves on a wet surface. However, if the maximum width of the annular groove 11 is set too large, larger trash stuck in the annular groove 11 is difficult to be carried out when the water is drained due to the limited impact force of the water. Therefore, in this embodiment, the A / L ratio satisfies the relationship: 0.470 ≤ A / L ≤ 0.494. When A / L is within the above ratio range, the length A of the first groove 12 will not be too long, thus avoiding the problem of the annular groove 11 being too narrow, which would reduce the drainage capacity of the annular groove 11. Similarly, the length A of the first groove 12 will not be too short, resulting in the maximum width of the annular groove 11 being too wide, ultimately making it easier for larger pieces of waste to get stuck in the annular groove 11. The value of A / L can be 0.470, 0.473, 0.476, 0.479, 0.482, 0.485, 0.488, 0.491, and 0.494.

[0051] It is clear that when the tire rolls, water flows into the annular groove 11. Since the first groove 12 is connected to the annular groove 11, if the maximum depth D2 of the first groove 12 is greater than the maximum depth D1 of the annular groove 11, most of the water in the annular groove 11 may form a water film within the annular groove 11, with only a small portion overflowing into the first groove 12. This makes it difficult for the water to drain out of the tire through the first groove 12, thus reducing the tire's anti-skid ability. Therefore, in this embodiment, to facilitate the drainage of water from the annular groove 11, the maximum depth D1 of the annular groove 11 is greater than or equal to the maximum depth D2 of the first groove 12.

[0052] Furthermore, the maximum depth D1 of the annular groove 11 and the maximum depth D2 of the first groove 12 satisfy the relationship: 0.25≤D2 / D1≤1.00. When the ratio of D1 to D2 satisfies the above relationship, the maximum depth of the first groove 12 will not be too shallow relative to the maximum depth of the annular groove 11. If the maximum depth of the first groove 12 is too shallow relative to the maximum depth of the annular groove 11, that is, D2 / D1 is less than 0.25, water in the first groove 12 may overflow to the outer circumference of the main body 10, eventually causing a water film to form on the outer circumference, affecting the tire's anti-skid and drainage performance. If D2 / D1 is greater than 1, water flowing from the annular groove 11 into the first groove 12 may not be completely drained, that is, water may remain in the groove of the first groove 12. The values ​​of D2 / D1 can be 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95, and 1.00.

[0053] Furthermore, the maximum depth D1 of the annular groove 11 satisfies the relationship: 0.5mm≤D1≤2.0mm.

[0054] It is understandable that the greater the maximum depth of the annular groove 11, i.e., D1 greater than 2.0 mm, the easier it is for debris to accumulate within the annular groove 11, leading to excessive debris buildup on the tire. Conversely, the lower the maximum depth of the annular groove 11, the more likely it is to disappear due to tire wear after a certain period of tire use, resulting in a significant decrease in the tire's anti-skid and drainage capabilities. Therefore, in this embodiment, the maximum depth D1 of the annular groove 11 needs to satisfy the relationship: 0.5 mm ≤ D1 ≤ 2.0 mm. In other words, when the maximum depth of the annular groove 11 is within the above range, it ensures that the tire still has good anti-skid and drainage capabilities after long-term use, while also preventing the annular groove 11 from becoming too deep, thus avoiding excessive debris accumulation. The value of D1 can be 0.5 mm, 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, 1.5 mm, 1.7 mm, 1.9 mm, and 2.0 mm.

[0055] Optionally, the maximum depth D2 of the first groove 12 satisfies the relationship: 0.5mm ≤ D2 ≤ 1.5mm. When D2 satisfies the above relationship, the maximum depth of the first groove 12 will not be too deep, thus avoiding excessive accumulation of debris within the first groove 12; at the same time, the maximum depth of the first groove 12 will not be too shallow, resulting in a shorter tire lifespan. The value of D2 can be 0.5mm, 0.7mm, 0.9mm, 1.1mm, 1.3mm, and 1.5mm. It is worth mentioning that when D1 and D2 are greater than 0.5mm, the tire wear time can exceed three years, meaning that the tire needs to wear out for more than three years before the first groove 12 or the annular groove 11 disappears.

[0056] Furthermore, the maximum depth D1 of the annular groove 11 and the maximum width L1 of the annular groove 11 satisfy the following relationship: 0.15≤L1 / D1≤1.2.

[0057] Understandably, if the maximum depth D1 of the annular groove 11 is set too large, while the maximum width L1 of the annular groove 11 is small (i.e., L1 / D1 is less than 0.15), the flow resistance of the fluid in the annular groove 11 will be large, making it difficult for the debris in the annular groove 11 to be carried out by water. Conversely, if the maximum depth D1 of the annular groove 11 is set too small, while the maximum width L1 of the annular groove is set too large, larger debris can easily enter the annular groove 11, and the annular groove 11 may disappear after a certain period of tire wear. The value of L1 / D1 can be 0.15, 0.30, 0.45, 0.60, 0.75, 0.90, 1.05, and 1.20.

[0058] Optionally, the maximum depth D2 and the maximum width L2 of the first groove 12 satisfy the following relationship: 0.6 ≤ L2 / D2 ≤ 1.2. When L2 / D2 satisfies the above relationship, the maximum width of the first groove 12 will not be too narrow relative to the depth of the first groove 12, thereby avoiding excessive flow resistance to the liquid in the first groove 12, making it difficult for the waste in the first groove 12 to be carried out by the liquid; the maximum width of the first groove 12 will also not be too wide relative to the depth of the first groove 12, causing waste to accumulate more easily in the first groove 12. The value of L2 / D2 can be 0.60, 0.75, 0.90, 1.05, and 1.20.

[0059] Furthermore, the maximum depth D1 of the annular groove 11, the maximum width L1 of the annular groove 11, the maximum depth D2 of the first groove 12, and the maximum width L2 of the first groove 12 satisfy the following relationship: 0.171≤(L1+L2) / (D1+D2)≤1.200.

[0060] Specifically, when the ratio of the sum of L1 and L2 to the sum of D1 and D2 is too high, i.e., (L1+L2) / (D1+D2) is greater than 1.200, there is a large connecting area at the connection between the first groove 12 and the annular groove 11, which makes it easier for debris to enter the first groove 12 or the annular groove 11. Conversely, when (L1+L2) / (D1+D2) is less than 0.171, the connecting area at the connection between the first groove 12 and the annular groove 11 is small, resulting in greater resistance to the liquid flow at the connection. This affects tire drainage and makes it difficult for the liquid to carry debris from the annular groove 11 into the first groove 12. The specific values ​​of (L1+L2) / (D1+D2) can be 0.171, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, and 1.2.

[0061] Furthermore, the first groove 12 has a first edge 121 and a second edge 122 located on the outer peripheral surface and disposed opposite to each other, and at least one of the first edge 121 and the second edge 122 is provided with a rounded corner 123; wherein, the radius R of the rounded corner 123 satisfies the relationship: R≥0.2mm.

[0062] It is understood that the main body 10 is typically made of an elastic material, such as rubber. When the main body 10 rolls on the ground, the first edge 121 and the second edge 122 of the first groove 12 are subjected to an external force opposite to the direction of travel of the main body 10, causing the tire to deform. When the external force is too great or the stress concentration on the first edge 121 and the second edge 122 is too great, the tire skin may peel off. Therefore, in this embodiment, rounded corners 123 are provided on the first edge 121 and the second edge 122 to reduce excessive stress concentration at the first edge 121 and the second edge 122, thereby improving the service life of the tire. In addition, the radius R of the rounded corner 123 should be greater than 0.2 mm to prevent excessive stress concentration on the first edge 121 and the second edge 122.

[0063] In one specific embodiment, the first groove 12 extends along the axial direction of the main body 10, and the first edge 121 and the second edge 122 are respectively arranged along the extension direction perpendicular to the first groove 12. Furthermore, in this embodiment, the edges of the annular groove 11 are not rounded 123. This is because the extension direction of the annular groove 11 is the same as the tire's travel direction, and the tire will not experience stress concentration on the edges of the annular groove 11. At the same time, although the rounded corner 123 can reduce stress concentration to some extent, its arrangement increases the surface area at the opening of the annular groove 11, making it easier for debris to enter the annular groove 11.

[0064] This application also provides the following specific embodiments to illustrate that the tire design of this application is less prone to trapping debris:

[0065] Example 1:

[0066] For waste with a radius between 1.5mm and 3mm, the tire of this application, which has a first groove 12 and an annular groove 11 on its outer circumferential surface, with L1 being 0.55mm and L2 being 0.5mm, compared with existing tires, which have L1 greater than 0.6mm and L2 greater than 0.6mm, after running for a certain period of time, the weight of the waste stuck by the tire of this application is 0.000g, while the weight of the waste stuck by the existing tire is 0.590g.

[0067] Example 2:

[0068] Unlike Example 1, the tested waste had a radius between 1 mm and 2 mm, such as millet. The weight of the waste obtained by the tire test in this application was 0.009 g, while the weight of the existing tire was 0.490 g.

[0069] Example 3

[0070] Unlike Example 1, the tested waste had a radius between 3mm and 5mm, such as mung beans or red beans. The weight of the waste stuck in the tires of this application was 0.00g, while the weight of the waste stuck in the tires of the prior art was 0.090g.

[0071] Example 4

[0072] Unlike Example 1, the tested waste with a radius of less than 1 mm, such as sand and dust, weighed 0.210 g when stuck using the tire test of this application, while the weight of the waste stuck by the tire of the prior art was 1.020 g.

[0073] Table 1:

[0074]

[0075] Through Examples 1, 2, 3, 4 and Table 1, it can be seen that when the cleaning equipment uses the tire of this application, the amount of garbage with a radius of 1.5mm to 5mm stuck on the tire is significantly reduced, and when the radius of the garbage is higher than 2mm, the garbage is more difficult to get stuck in the first groove 12 or the annular groove 11.

[0076] In summary, the tire of this application limits the maximum width of the first groove 12 and the annular groove 11, thereby preventing larger debris from getting stuck in the first groove 12 and the second groove. Especially when the radius of the debris is greater than 2mm, it is more difficult for this debris to get stuck in the first groove 12 and the second groove. This means that the maintenance cycle of the cleaning equipment can be extended, thus reducing the maintenance cost of the cleaning equipment to some extent. On the other hand, this application also limits the depth of the first groove 12 and the annular groove 11. While ensuring the tire's service life, it avoids the first groove 12 or the annular groove 11 from being too deep, which would make it easier for debris to accumulate in the first groove 12 or the second groove. Furthermore, the first groove 12 of this application is provided with a first edge 121 and a second edge 122, both of which are rounded with corners 123 to avoid excessive stress on the first edge 121 and the second edge 122, which could easily damage the tire.

[0077] 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.

[0078] 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.

[0079] 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.
