Accordingly, other embodiments are within the scope of the following claims.
In addition, the drawings in the following description are only preferred embodiments of the present invention, and it is obvious to those skilled in the art that other drawings can be obtained based on the drawings without inventive efforts. In addition, the present invention is not limited to these embodiments, and any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Furthermore, in the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways than those described herein, and it will be apparent to those of ordinary skill in the art that the present application is not limited to the specific embodiments disclosed below.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular is intended to include the plural unless the context clearly dictates otherwise, and it should be further understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of the stated features, steps, operations, devices, components, and/or combinations thereof.
The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
In the description of the present application, it is to be understood that the orientation or positional relationship indicated by the directional terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc., is typically an orientation or positional relationship based on a coordinate system shown in the front view of the device itself or the corresponding sub-component, and that the set of coordinate systems will not rotate with it when other directional views are discussed. In addition, in the case of a rod-like or elongated member, the term "front end" has the same meaning as the term "head", and the term "rear end" has the same meaning as the terms "tail end" and "end". Rather, the foregoing directional terms are used merely to facilitate describing the present application and to simplify the description, and they do not indicate or imply that the device or element so referred to must be constructed and operated in a particular orientation or orientation unless otherwise indicated and should not be considered as limiting the scope of the present application; further, the terms "inner and outer" with respect to orientation refer to the inner and outer relative to the profile of the respective component itself.
Furthermore, spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
It should be noted that the terms "first", "second", etc. are used to define the components, and are only used to facilitate distinguishing the corresponding components, and if not stated otherwise, the terms have no special meaning, especially, have no special meaning in "main, secondary" or arrangement order, and therefore, should not be construed as limiting the scope of the present application.
