[0003] However, in the relevant technologies, the panel needs to be opened to disassemble the fresh air filter, making the disassembly of the fresh air filter inconvenient. Utility Model Content

[0004] To overcome the technical problem that the fresh air filter needs to be disassembled by opening the panel in related technologies, which makes the disassembly of the fresh air filter inconvenient, this disclosure provides an indoor air conditioning unit and an air conditioner.

[0005] In a first aspect, this disclosure provides an indoor unit for an air conditioner, comprising:

[0006] The housing has an air outlet and a disassembly port located at one end of the air outlet in the extending direction;

[0007] A fresh air housing, disposed within the housing and located at the same end as the air outlet as the disassembly port, the fresh air housing having a fresh air flow channel; and

[0008] A filter assembly is detachably installed in the fresh air housing, and the filter assembly is detached from or extends into the fresh air duct through the detachment port.

[0009] In some embodiments, the indoor unit of the air conditioner further includes an air guide plate, which is movably installed on the housing and has an extreme position to avoid the air outlet;

[0010] Wherein, the air guide plate avoids the disassembly port when it is in the extreme position, and does not interfere with the travel trajectory of the filter assembly when it is installed or removed from the fresh air housing.

[0011] In some embodiments, when the air guide plate is in the extreme position, the air guide plate guides the airflow at the air outlet downward or upward.

[0012] In some embodiments, the indoor unit of the air conditioner further includes a rotating arm, which is rotatably connected to the housing and rotatably connected to the air guide plate. When the rotating arm extends out of the air outlet, the air guide plate rotates relative to the rotating arm to the extreme position.

[0013] In some embodiments, the air guide plate also has a closed position that closes the air outlet, and when the air guide plate is in the closed position, it blocks the disassembly port.

[0014] In some embodiments, the indoor unit of the air conditioner further includes a decorative insert that is detachably disposed at the disassembly port.

[0015] In some embodiments, the fresh air duct has a fresh air inlet, and the indoor unit of the air conditioner further includes a fan, which is disposed in the fresh air duct and has a fresh air outlet;

[0016] The filter assembly is disposed between the fresh air inlet and the fan, and the fan is used to guide fresh air from the fresh air inlet through the filter assembly to the fresh air outlet.

[0017] In some embodiments, the fan is a centrifugal fan, and at least one side of the fan in the axial direction is spaced apart from the inner wall of the fresh air duct.

[0018] In some embodiments, the filter assembly is located on one side of the fan along its axial direction.

[0019] In some embodiments, the filter assembly is located on one side of the fan in the radial direction.

[0020] In some embodiments, two filter assemblies are provided along the axial direction of the fan.

[0021] In some embodiments, the filter assembly is bent, and the filter assembly bends toward or away from the fan;

[0022] Alternatively, the filter assembly may be tilted relative to the direction in which fresh air flows toward the fan.

[0023] In some embodiments, the fresh air housing is provided with an installation port for the filter assembly to extend into the fresh air flow channel, and one end of the filter assembly is provided with a sealing head, which seals the installation port after the filter assembly extends into the fresh air flow channel from the installation port.

[0024] In some embodiments, the sealing head is located at least partially outside the mounting port when sealing the mounting port.

[0025] In some embodiments, the inner wall of the fresh air duct is provided with a slot, and the filter assembly is slidably engaged in the slot.

[0026] In some embodiments, the fresh air housing includes a first housing and a second housing fixed to each other, the first housing and the second housing clamping the filter assembly.

[0027] In some embodiments, the first housing has a first opening, the second housing has a second opening, and the first opening and the second opening are combined to form an installation port, which allows the filter assembly to extend into the fresh air duct.

[0028] Secondly, this disclosure also provides an air conditioner, including an indoor unit as described in any of the preceding claims.

[0029] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: In this solution, since the casing of the indoor unit of the air conditioner has a disassembly port, and the filter assembly can be detached from or extended into the fresh air duct of the fresh air casing through the disassembly port, the filter assembly can be directly removed from the fresh air duct through the disassembly port during the disassembly and assembly process. This facilitates cleaning or replacement maintenance of the filter assembly, and the maintained filter assembly can be reinserted into the fresh air duct through the disassembly port. Thus, the disassembly and assembly of the filter assembly can be achieved without disassembling the panel, improving convenience and enhancing the user experience.

[0030] Furthermore, since the disassembly port is located at one end of the air outlet extension direction, the disassembly port can be displayed as a fake air outlet, avoiding openings in other parts of the panel, thus improving the aesthetics.

[0031] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0050] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0051] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0052] To improve user comfort, air conditioner indoor units are equipped with a fresh air function, introducing fresh air from the outside into the room through a fresh air module to improve indoor air quality. However, in these technologies, the fresh air filter needs to be removed by opening the panel, making the removal of the fresh air filter rather inconvenient.

[0053] To address the technical issue in related technologies where removing the fresh air filter requires opening the panel, making filter removal inconvenient, this solution provides an indoor air conditioning unit and air conditioner that allows the filter assembly to be directly removed from the fresh air duct through a disassembly port. This facilitates cleaning or replacement of the filter assembly, and the maintained filter assembly can then be reinserted into the fresh air duct through the disassembly port. Thus, filter assembly can be installed and removed without disassembling the panel, significantly improving convenience.

[0054] Please refer to the figure. Figures 1 to 3 The air conditioning indoor unit provided in this application includes a housing 1, a fresh air housing 2, and a filter assembly 3; the housing 1 has an air outlet 1a and a disassembly port 1b located at one end of the extension direction of the air outlet 1a; the fresh air housing 2 is disposed in the housing 1 and is located at the same end of the air outlet 1a as the disassembly port 1b, and the fresh air housing 2 has a fresh air flow channel 2a; the filter assembly 3 is detachably installed in the fresh air housing 2, and the filter assembly 3 is detached from or extends into the fresh air flow channel 2a through the disassembly port 1b.

[0055] In this design, the indoor unit casing 1 of the air conditioner has a disassembly port 1b, and the filter assembly 3 can be detached from or inserted into the fresh air duct 2a of the fresh air housing 2 via the disassembly port 1b. Therefore, during the disassembly and assembly of the filter assembly 3, it can be directly removed from the fresh air duct 2a through the disassembly port 1b for cleaning or replacement maintenance. The maintained filter assembly 3 can then be reinserted into the fresh air duct 2a through the disassembly port 1b. This eliminates the need to disassemble the panel, improving convenience and enhancing the user experience. Furthermore, since the disassembly port 1b is located at one end of the extension direction of the air outlet 1a, it can function as a dummy air outlet, avoiding openings in other parts of the panel and improving aesthetics.

[0056] It should be noted that the filter assembly 3 can be configured as a filter screen, filter cotton, non-woven fabric, or filter paper combined with a support frame, or other forms, as long as it can achieve fresh air filtration and be detachably connected to the fresh air housing 2. Specifically, in this solution, the filter assembly 3 includes a filter frame and a filter screen. The filter frame is detachably installed in the fresh air flow channel 2a of the fresh air housing 2, and the filter screen is installed on the filter frame. The filter frame and the fresh air housing 2 can be detachably connected by elastic clips, bolts, or magnets. It should be understood that the extension direction of the air outlet 1a refers to its length direction.

[0057] In one embodiment, the indoor unit of the air conditioner also includes an air guide plate 4, which is movably installed on the housing 1 and has an extreme position that avoids the air outlet 1a; wherein, when the air guide plate 4 is in the extreme position, it avoids the disassembly port 1b and does not interfere with the travel trajectory of the filter assembly 3 in the fresh air housing 2.

[0058] In this embodiment, a guide vane 4 is also provided on the housing 1 to guide the airflow direction of the air outlet 1a, further improving the user experience. At the same time, when it is necessary to disassemble or assemble the filter assembly 3, the guide vane 4 can be moved to its limit position. At this time, the guide vane 4 avoids the disassembly port 1b, and the filter assembly 3 will not interfere with the guide vane 4 during disassembly or assembly, ensuring the normal disassembly or assembly of the filter assembly 3.

[0059] It should be understood that when the air conditioner vents downwards, it has the advantage of improving the efficiency of hot and cold air circulation and optimizing human comfort. It is especially suitable for air conditioning heating and energy-saving cooling scenarios in summer, which makes the downward airflow of the air guide plate 4 the most common application scenario.

[0060] Specifically, during heating, hot air is less dense than cold air and naturally tends to rise. The downward-directing airflow vane 4 directly pushes the hot air towards the ground, precisely solving the problem of hot head and cold feet in traditional heating systems. Furthermore, the hot air rises naturally from the ground, quickly filling the entire room and preventing heat from concentrating in the ceiling area and causing waste.

[0061] When cooling, downward airflow doesn't blow cold air directly at the body. Instead, it achieves indirect cooling through a well-designed angle, improving the user experience. The cold air is first directed towards the floor or walls, then reflected and diffused as a gentle airflow. This avoids direct skin contact that could cause headaches or joint discomfort, making it especially suitable for the elderly and children. The downward-directed cold air, due to its higher density, naturally diffuses towards the ground, gradually lowering the room temperature from bottom to top, resulting in a more gentle and less abrupt feeling.

[0062] Therefore, in one embodiment, when the air guide plate 4 is in the extreme position, the air guide plate 4 guides the airflow of the air outlet 1a downward or upward.

[0063] In this embodiment, since the air guide plate 4 is used in many scenarios of blowing air downwards, it is preferable to set the extreme position of the air guide plate 4 to the position when blowing air downwards, so that when the user disassembles or assembles the filter component 3, the air guide plate 4 will usually not interfere with the filter component 3, further improving the user experience.

[0064] It should be noted that the form in which the air guide plate 4 moves relative to the housing 1 is not limited. In one embodiment, the air guide plate 4 is slidably connected to the housing 1, achieving both avoidance and air guidance during the sliding process. In another embodiment, the air guide plate 4 is detachably connected to the housing 1 by bolts or clips, etc., so as to be movably set relative to the housing 1; when air guidance is required, the air guide plate 4 is installed on the housing 1 and positioned corresponding to the air outlet 1a; and when it is necessary to avoid the disassembly port 1b and the filter assembly 3, the air guide plate 4 is removed from the housing 1.

[0065] In one embodiment, the indoor unit of the air conditioner also includes a rotating arm 5, which is rotatably connected to the housing 1 and rotatably connected to the air guide plate 4. When the rotating arm 5 extends out of the air outlet 1a, the air guide plate 4 rotates to its limit position relative to the rotating arm 5.

[0066] In this embodiment, the position of the air guide plate 4 relative to the air outlet 1a is adjusted by rotating the aforementioned rotating arm 5, allowing for multi-directional stepless adjustment of the air outlet direction. Specifically, the rotating arm 5 rotates to its limit position when extending out of the air outlet 1a, ensuring that the air guide plate 4 effectively avoids the disassembly port 1b and the filter assembly 3. Furthermore, in some embodiments, the rotating arm 5 is driven to rotate by a servo motor.

[0067] In one embodiment, the air guide plate 4 also has a closed position for closing the air outlet 1a, and when the air guide plate 4 is in the closed position, it blocks the disassembly port 1b.

[0068] In this embodiment, when the rotating arm 5 rotates to the position where it is housed within the air outlet 1a, the air guide plate 4 simultaneously closes both the air outlet 1a and the disassembly port 1b, preventing the disassembly port 1b from being exposed to the external environment for an extended period, thereby preventing dust accumulation in the disassembly port 1b. It should be noted that, in one embodiment, the disassembly port 1b is connected to the air outlet 1a, allowing the air to be delivered through the disassembly port 1b, thus increasing the air diffusion area.

[0069] In one embodiment, the indoor unit of the air conditioner also includes a decorative insert, which is detachably disposed at the disassembly port 1b.

[0070] In this embodiment, when it is not necessary to disassemble the filter assembly 3, the decorative insert can be installed at the disassembly port 1b of the housing 1. On the one hand, it can prevent dust accumulation at the disassembly port 1b, and on the other hand, the decorative insert can also serve a decorative purpose.

[0071] It should be noted that the embodiment of the decorative insert can be independent of the embodiment in which the air guide plate 4 blocks the disassembly port 1b when closed. That is, in another embodiment, the air guide plate 4 does not block the disassembly port 1b when closed, and in this case, the disassembly port 1b is blocked only by the decorative insert. Alternatively, the embodiment of the decorative insert can coexist with the embodiment in which the air guide plate 4 blocks the disassembly port 1b when closed; in this case, the air guide plate 4 blocks the decorative insert when closed, and the decorative insert is exposed when the air guide plate 4 is rotated to its limit position.

[0072] Furthermore, the decorative insert can be detachably connected to the housing 1 via clips, magnets, or bolts. Specifically, in this solution, the decorative insert is in the form of a decorative panel, with a disassembly pattern and text markings for the filter assembly 3 on the outer side of the decorative panel, and the decorative panel is detachably connected to the housing 1 via magnetic attraction.

[0073] In one embodiment, please refer to Figures 4 to 7 The fresh air duct 2a has a fresh air inlet 2c, and the indoor air conditioning unit also includes a fan 6. The fan 6 is located in the fresh air duct 2a and has a fresh air outlet 6a. The filter assembly 3 is located between the fresh air inlet 2c and the fan 6. The fan 6 is used to guide fresh air from the fresh air inlet 2c through the filter assembly 3 to the fresh air outlet 6a.

[0074] In this embodiment, the fresh air inlet 2c is connected to the external environment through a duct. During the rotation of the fan 6, the outside air is guided from the fresh air inlet 2c to the fresh air outlet 6a, and finally enters the room. The fresh air is filtered by the filter assembly 3 during its flow to ensure that the fresh air delivered into the room is clean.

[0075] In one implementation, please refer to Figure 8 The fan 6 is a centrifugal fan, and the fan 6 is spaced apart from the inner wall of the fresh air flow channel 2a on at least one side in the axial direction.

[0076] In this embodiment, the fan 6 is configured as a centrifugal fan, with axial air intake and radial air exhaust. Therefore, at least one side of the fan 6 along its axial direction is spaced apart from the inner wall of the fresh air duct 2a to ensure normal air intake. Specifically, in this design, both sides of the fan 6 along its axial direction are spaced apart from the inner wall of the fresh air duct 2a, allowing simultaneous air intake from both sides of the fan 6 along its axial direction, thus improving air delivery efficiency.

[0077] In one embodiment, the filter assembly 3 is located on one side of the fan 6 in the axial direction.

[0078] In this embodiment, the filter assembly 3 and the fan 6 are arranged sequentially along the axial direction of the fan 6, so that the fresh air, after passing through the filter assembly 3, directly points to the axial air intake side of the fan 6, shortening the fresh air travel distance, improving airflow efficiency, and reducing energy consumption. It should be noted that in this embodiment, the axial direction of the fan 6 is the same as the extension direction of the air outlet 1a.

[0079] It should be noted that the radial dimension of the fan 6 is usually smaller than that of the casing 1, that is, there is usually a certain space between the fan 6 and the inner wall of the casing 1 in the radial direction.

[0080] Therefore, in one embodiment, the filter assembly 3 is located on one side of the fan 6 in the radial direction.

[0081] In this embodiment, the filter assembly 3 and the fan 6 are arranged radially along the fan 6, making full use of the space between the fan 6 and the inner wall of the casing 1 in the radial direction, avoiding additional space occupation of the casing 1 in the axial direction of the fan 6, making the indoor unit of the air conditioner relatively compact and reducing the size of the casing 1. Similarly, in this solution, the axial direction of the fan 6 is the same as the extension direction of the air outlet 1a. And the filter assembly 3 is located on the lower side of the fan 6, arranged sequentially with the fan 6 in the vertical direction.

[0082] In one embodiment, two filter components 3 are arranged along the axial direction of the fan 6.

[0083] In this embodiment, a filter assembly 3 is respectively provided on the air inlet side at both ends of the fan 6, so that the two air inlet sides of the fan 6 correspond one-to-one with the two filter assemblies 3, thereby improving the fresh air filtration efficiency and ensuring the cleanliness of the fresh air entering the room. It should be noted that, in one embodiment, when two filter assemblies 3 are provided, the two filter assemblies 3 can be installed as a single unit and can be disassembled and assembled via a mounting port 2b. In another embodiment, when two filter assemblies 3 are provided, two mounting ports 2b are correspondingly provided, located at the same end of the air outlet, and corresponding one-to-one with the two filter assemblies 3.

[0084] In one embodiment, the filter assembly 3 is bent, and the filter assembly 3 bends toward or away from the fan 6; or, see [link to relevant documentation]. Figure 6 and Figure 9 The filter assembly 3 is tilted relative to the direction of airflow from the fresh air fan 6.

[0085] In this embodiment, when the filter assembly 3 is bent, its frontal area increases, thereby improving the fresh air filtration efficiency. When the filter assembly 3 bends towards the fan 6, the fresh air, after entering the fresh air flow channel 2a from the fresh air inlet 2c, first contacts the concave surface of the filter assembly 3. At this time, the filter assembly 3 has the function of converging the fresh air, accelerating the fresh air flow rate, allowing the fresh air to quickly pass through the filter assembly 3 and flow towards the fan 6, improving the fresh air filtration efficiency. Conversely, when the filter assembly 3 bends away from the fan 6, the fresh air, after entering the fresh air flow channel 2a from the fresh air inlet 2c, first contacts the convex surface of the filter assembly 3. At this time, the filter assembly 3 has the function of guiding the fresh air diffusion, making the fresh air diffuse evenly, reducing airflow impact and turbulence, lowering overall wind resistance, and allowing the fresh air to evenly contact all parts of the filter assembly 3, improving the fresh air purification capacity. Furthermore, when the filter assembly 3 bends away from the fan 6, a space is formed on the side near the fan 6, which can be used to install the fan 6, improving space utilization.

[0086] Furthermore, in one embodiment, the filter assembly 3 is tilted relative to the direction of the fresh air flow towards the fan 6, allowing the filter assembly 3 to expand its effective filtration area within a limited space. Simultaneously, when the filter assembly 3 is tilted as described above, it guides the fresh air to flow along the tilted surface of the filter assembly 3. In this case, the fresh air passes smoothly through the filter assembly 3 along the tilt angle, reducing energy loss caused by airflow rebound and eddies, lowering airflow impact, and thus reducing operating noise.

[0087] Furthermore, the tilt angle allows gravity to assist in the deposition of impurities. Some larger particles (such as dust and hair) will slide down the filter surface to the dust collection area below due to gravity after contacting the tilted filter under the action of airflow, thus preventing impurities from clogging the air pores on the filter surface.

[0088] Meanwhile, the curved filter assembly 3 can be directly adapted to curved air ducts, circular fans 6, etc., reducing the number of duct bends and avoiding spatial conflicts between the filter assembly 3 and other components (such as circuit boards and motors), thus reducing the overall design complexity of the equipment. In addition, the curved design can flexibly fit the curved surface structure inside the equipment (such as circular air ducts and curved shells), making full use of corner spaces and improving space utilization.

[0089] In one embodiment, the filter component 3 is arranged in an arc-shaped bend.

[0090] In this embodiment, the surface of the arc-shaped filter component 3 is relatively smooth, which can disperse the force and allow the fresh air to flow smoothly along the arc-shaped surface, significantly reducing resistance and energy consumption. Specifically, when the fresh air comes into contact with the airflow or water flow on the arc-shaped surface, it will naturally conform to the curved surface and avoid the rebound and eddies caused by impacting the flat surface or sharp angle, thus reducing fluid resistance. The reduction in resistance can directly reduce the energy demand for driving the fluid and at the same time reduce operating noise.

[0091] Furthermore, the outer surface of the arc-shaped filter has no obvious dead corners, and users can clean impurities along the curved surface in one go when cleaning with a brush or vacuum cleaner; some washable filters are also easier to rinse due to their arc-shaped structure, reducing blind spots in cleaning.

[0092] In one embodiment, the fresh air housing 2 is provided with an installation port 2b for the filter assembly 3 to extend into the fresh air flow channel 2a. One end of the filter assembly 3 is provided with a sealing head 31, which seals the installation port 2b after the filter assembly 3 extends into the fresh air flow channel 2a from the installation port 2b.

[0093] In this embodiment, when installing the filter assembly 3, the filter assembly 3 is fed from the disassembly port 1b into the installation port 2b, and the filter assembly 3 continues to be fed in until the main body of the filter assembly 3 enters the fresh air flow channel 2a. The sealing head 31 then seals the installation port 2b to ensure the airtightness of the fresh air flow channel 2a and prevent unfiltered fresh air from directly diffusing into the room through the installation port 2b. When it is necessary to disassemble the filter assembly 3, the sealing head 31 is pulled out of the fresh air flow channel 2a sequentially through the installation port 2b and the disassembly port 1b.

[0094] It should be noted that in this solution, the installation port 2b is located on the side of the fresh air housing 2 facing the disassembly port 1b, so that the installation port 2b is directly opposite the disassembly port 1b, which further facilitates the user to install and remove the filter assembly 3 through the disassembly port 1b.

[0095] In one embodiment, the sealing head 31 is at least partially located outside the mounting opening 2b when sealing the mounting opening 2b.

[0096] In this embodiment, after the filter assembly 3 is installed into the fresh air duct 2a, the sealing head 31 of the filter assembly 3 is located outside the installation port 2b, making it easy for the user to remove and disassemble, thus improving convenience. It should be noted that in one embodiment, the sealing head 31 is made of rubber material, or the outer periphery of the sealing head 31 is covered with rubber material to ensure the sealing performance of the sealing head 31 to the installation port 2b. Furthermore, the surface of the rubber material is provided with anti-slip grooves or anti-slip protrusions to prevent detachment.

[0097] It should be noted that the filter assembly 3 and the fresh air housing 2 can be detachably connected by bolts, elastic clips or magnetic attraction.

[0098] In one embodiment, the inner wall of the fresh air duct 2a is provided with a slot 2d, and the filter component 3 is slidably engaged in the slot 2d.

[0099] In this embodiment, when the filter assembly 3 is installed or removed from the fresh air duct 2a, it can be guided to slide via the slot 2d, ensuring stable connection between the filter assembly 3 and the fresh air housing 2. Specifically, in this solution, the slot 2d is arranged in an arc-shaped bend corresponding to the filter assembly 3.

[0100] In one embodiment, please refer to Figure 10 The fresh air housing 2 includes a first housing 21 and a second housing 22 that are fixed to each other, and the first housing 21 and the second housing 22 hold the filter assembly 3.

[0101] In this embodiment, the fresh air housing 2 is assembled from a first housing 21 and a second housing 22. The individual housing structure is relatively regular, allowing for simpler molds and reducing the development cost and processing difficulty of complex one-piece molds, while also lowering the scrap rate during production. This also facilitates the pre-assembly of components such as the fan 6 and filter assembly 3 between the first housing 21 and the second housing 22 before overall assembly, improving assembly efficiency. It should be noted that the first housing 21 and the second housing 22 can be connected using snap-fit, bolt, or tenon joints.

[0102] In one embodiment, the first housing 21 has a first opening 21a, and the second housing 22 has a second opening 22a. The first opening 21a and the second opening 22a are combined to form an installation port 2b, which allows the filter assembly 3 to extend into the fresh air flow channel 2a.

[0103] In this embodiment, the mounting port 2b is formed by the openings of the two housings, avoiding the reduction of the housing structure strength and stress concentration caused by opening a complete mounting port 2b on a single housing. After the first housing 21 and the second housing 22 are joined, the filter assembly 3 can detach from the mounting port 2b formed by the two housings or extend into the fresh air flow channel 2a. It should be noted that a sealing ring is provided between the first housing 21 and the second housing 22.

[0104] Furthermore, this application also provides an air conditioner, which includes an indoor unit as described above. The specific structure of the indoor unit is the same as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the embodiments of the above-described indoor unit, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0105] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0106] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0107] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0108] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0109] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0110] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0111] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0112] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0113] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0114] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
