Description

Technical Field

[0001] This invention relates to the field of air cooler technology, and more specifically, to a cooling head and an air cooler having therein. Background Technology

[0002] Currently, existing air coolers are direct evaporative cooling and humidifying devices. Their working principle is that a water pump sends water from the water tank to the evaporator. When the air passes through the evaporator, it carries moisture. The principle of water evaporation and heat absorption is used to achieve the purpose of lowering the ambient temperature, humidifying, and providing a comfortable fan effect.

[0003] Specifically, the prior art discloses an evaporative cooling fan. The evaporative cooling pad mounting frame has a water inlet and multiple water outlets connected to the inlet. The inlet is connected to a water supply pipe, which is mounted on a support. A water collection port is located at the bottom of the mounting frame, and a water collection trough is located on the support. The water collection port is connected to the water collection trough. The evaporative cooling pad is mounted within the mounting frame, with the water outlets facing the pad. When the cooling fan is operating, water flows through the water supply pipe into the inlet of the mounting frame and finally flows out through the water outlets onto the evaporative cooling pad, humidifying it. Air flowing through the pad carries moisture from it, thus humidifying and cooling the air. Water from the pad flows through the water collection port into the water collection trough on the support. By fixing the mounting frame to the support, the evaporative cooling pad does not swing with the fan head when the fan head swings within the support.

[0004] However, the above method, which humidifies and cools the air by having it flow through the evaporative cooling pad and carry away moisture from the pad, cannot meet users' airflow requirements for evaporative air coolers. Furthermore, outdoor evaporative air coolers are generally large industrial fans. Although they have two or three evaporative cooling pads, the air intake still needs to come from the rear, with the sides only providing auxiliary airflow. This results in the side evaporative cooling pads not being as effective, leading to low evaporation efficiency. Additionally, the airflow range of evaporative air coolers on the market is limited, failing to provide users with a comfortable experience. Summary of the Invention

[0005] The main objective of this invention is to provide a cooling head and a cooling fan having the same, so as to solve the problem that the air outlet method of the cooling fan in the prior art cannot meet the user's needs.

[0007] Furthermore, there are at least two air inlets, and the machine head also includes a drive device disposed inside the housing. The drive device is connected to the air duct assembly to drive the air duct assembly to rotate. At least two air inlets are arranged opposite to each other, and the air inlet directions of the at least two air inlets are a first direction and a second direction, respectively.

One of the first mating part and the second mating part is a protrusion, and the other of the first mating part and the second mating part is a recess. The protrusion extends into the recess to slide along the extension direction of the recess, so that the air duct assembly can rotate relative to the outer casing. The extension direction of the recess is the circumferential direction of the air duct assembly.

[0009] Furthermore, the machine head also includes a transmission assembly located inside the housing, through which the drive device drives the air duct assembly to rotate; wherein, there is one transmission assembly; or there are two transmission assemblies, with the two transmission assemblies located on both sides of the second mating part respectively.

[0010] Furthermore, the drive unit has a drive shaft, and the transmission assembly includes a gear connected to the drive shaft; a rack disposed on the outer peripheral surface of the air duct assembly and meshing with the gear; wherein the extending direction of the rack is consistent with the circumferential direction of the outer peripheral surface.

[0011] Furthermore, the air head includes at least two baffles, both of which are connected to the air duct assembly and located on both sides of the air outlet; the air outlet has a first air outlet direction and a second air outlet direction arranged at an angle, when the air outlet discharges air along the first air outlet direction, the air outlet communicates with a portion of the opening, and one baffle blocks the other portion of the opening; when the air outlet discharges air along the second air outlet direction, the air outlet communicates with a portion of the opening, and another baffle blocks the other portion of the opening.

[0012] Furthermore, the housing is also provided with at least two sets of guide sections spaced apart circumferentially along the air duct assembly. The at least two sets of guide sections are provided in correspondence with at least two baffles. Each set of guide sections includes at least one guide structure, and the guide structure includes a bending section. Each baffle overlaps with the bending section of its corresponding guide section to slide along the bending section.

[0013] Furthermore, a bracket is also provided inside the outer casing, and the evaporator is mounted on the bracket.

[0014] Furthermore, there are at least two air inlets. The outer shell includes a first sub-shell, which includes an arc-shaped enclosure and a first flat plate. The arc-shaped enclosure is disposed on the surface of the first flat plate and has a notch. The second sub-shell includes an arc-shaped plate and a second flat plate. The arc-shaped plate is disposed on the surface of the second flat plate and forms an opening around the notch. Both the second flat plate and the arc-shaped plate are connected to the arc-shaped enclosure. The first flat plate is provided with at least one air inlet, and the second flat plate is provided with at least one other air inlet.

[0015] Furthermore, the air duct structure includes an air duct shell with interconnected mounting ports and an arc-shaped air duct, the air outlet of which is the air outlet; a mounting bracket connected to the air duct shell and located at the mounting port, and the fan mounted on the mounting bracket.

[0016] The present invention also provides a cooling fan, including a fan head, wherein the fan head is the aforementioned fan head.

[0017] Furthermore, the compressor head also includes a water tank, and each evaporator includes a buffer structure. The buffer structure has a water inlet, a water storage tank, and multiple water outlets. The water inlet is connected to each water outlet through the water storage tank and is connected to the water tank. A wet curtain structure is connected to the buffer structure and located below the buffer structure. The liquid flowing out from each water outlet flows to the wet curtain structure to wet the wet curtain structure. The multiple water outlets are spaced apart along the length and / or width of the wet curtain structure. A return water hole is provided at the bottom of the outer shell to allow the liquid flowing out of the wet curtain structure to flow back into the water tank through the return water hole.

[0018] Furthermore, the air cooler also includes an oscillating assembly, a support rod, and a water tank connected in sequence. The housing is connected to the support rod via the oscillating assembly, and at least a portion of the oscillating assembly is movably configured to drive the housing to rotate around a preset axis.

The air duct structure has an air outlet, and the air inlet communicates with the opening through the air outlet. The evaporator is disposed within the housing, opposite to the air inlet and located between the air inlet and the air duct assembly. The position of the air outlet is adjustable. Thus, with the above configuration, after the fan located within the air duct structure is started, air enters through at least one air inlet on the housing. The gas entering through the air inlet flows through at least one corresponding evaporator. Each evaporator cools and condenses the gas flowing through it, forming cold air. Driven by the fan, the cold air flows into the air duct structure and is blown out through the air outlet of the air duct structure, thereby enabling the cooling fan to achieve side air intake. Meanwhile, when it is necessary to adjust the airflow direction of the air cooler, the air duct component can be moved (e.g., rotated) relative to the outer casing to adjust the airflow direction of the air outlet, thereby achieving the purpose of the air cooler taking in air from the side and blowing air from multiple angles. This solves the problem that the airflow method of the air cooler in the prior art cannot meet the user's needs and improves the user experience. Attached Figure Description

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 9 As shown, applying the technical solution of the present invention, a compressor head is provided. The compressor head includes a housing 10, an air duct assembly 20, and an evaporator 30. The housing 10 has an air inlet 11 and an opening 12. The air duct assembly 20 includes an air duct structure 21 and a fan 22 disposed within the air duct structure 21. The air duct structure 21 has an air outlet 23, and the air inlet 11 communicates with the opening 12 through the air outlet 23. The evaporator 30 is disposed within the housing 10, opposite to the air inlet 11 and located between the air inlet 11 and the air duct assembly 20. The air duct assembly 20 is movably disposed within the housing 10 so that the position of the air outlet 23 can be adjusted.

[0034] Applying the technical solution of this embodiment, the above-mentioned setup, after starting the fan 22 located in the air duct structure 21, allows air to enter through at least one air inlet 11 on the outer casing 10. The gas entering through the air inlet 11 flows through at least one corresponding evaporator 30. Each evaporator 30 cools and condenses the gas flowing through it, forming cold air. Driven by the fan 22, the cold air flows into the air duct structure 21 and is blown out through the air outlet 23 of the air duct structure 21, so that the cooling fan can achieve side air intake. At the same time, when it is necessary to adjust the air outlet direction of the cooling fan, the air duct adjustment component 20 can be operated to move (e.g., rotate) relative to the outer casing 10, thereby adjusting the air outlet direction of the air outlet 23, so as to achieve the purpose of side air intake and multi-angle air blowing of the cooling fan, thereby solving the problem that the air outlet mode of the cooling fan in the prior art cannot meet the user's needs and improving the user experience.

[0035] In this embodiment, there are two air inlets 11 and two evaporators 30. The two evaporators 30 are arranged in a one-to-one correspondence with the two air inlets 11, and each evaporator 30 is located between its corresponding air inlet 11 and the air duct assembly 20.

[0036] It should be noted that the number of air inlets 11 is not limited to this and can be adjusted according to operating conditions and usage requirements. Optionally, there may be two, three, four, five, six, or more air inlets 11.

[0037] It should be noted that the number of evaporators 30 is not limited to this and can be adjusted according to operating conditions and usage requirements. Optionally, there may be two, three, four, five, six, or more evaporators 30.

[0038] In this embodiment, there are two air inlets 11 and two evaporators 30, with the two evaporators 30 corresponding to the two air inlets 11.

[0039] like Figure 1As shown, there are at least two air inlets 11, and the machine head also includes a drive device 41. The drive device 41 is disposed inside the housing 10 and is drivenly connected to the air duct assembly 20 to drive the air duct assembly 20 to rotate. At least two air inlets 11 are arranged opposite each other, and the air intake directions of the at least two air inlets 11 are a first direction and a second direction, respectively. The first direction and the second direction are arranged parallel to each other, and the rotation axis of the air duct assembly 20 is parallel to the first direction. In the above configuration, the drive device 41 is a stepper motor, and a mounting position for the drive device 41 is also provided inside the housing 10. The drive device 41 is mounted in the mounting position and fixed with screws, and the drive device 41 is drivenly connected to the outer surface of the air duct assembly 20. An air outlet grille is provided at the air outlet 23 of the air duct assembly 20 so that the air duct assembly 20 can be driven to rotate by the drive device 41 so that the air outlet 23 of the air duct assembly 20 is blown out from the air outlet grille in a horizontal direction (horizontal air outlet) or a vertical direction (up and down air outlet) to provide users with a comfortable user experience.

[0040] Optionally, a first mating part 42 is provided inside the outer casing 10, and a second mating part 43 is provided on the air duct assembly 20. One of the first mating part 42 and the second mating part 43 is a protrusion, and the other is a recess. The protrusion extends into the recess and slides along the extension direction of the recess, so that the air duct assembly 20 can rotate relative to the outer casing 10. The extension direction of the recess is the circumferential direction of the air duct assembly 20. This arrangement allows for more flexible selection of the structure of the first mating part 42 and the second mating part 43 to meet different usage requirements and working conditions, and also improves the processing flexibility of the operator.

[0041] In this embodiment, the first mating part 42 is a sliding groove, and the second mating part 43 is a sliding rod. The sliding groove and the sliding rod are connected and both are arc-shaped structures. With the above arrangement, the sliding rod on the air duct assembly 20 extends into the sliding groove inside the housing 10 and is slidably arranged along the extension direction of the sliding groove. This allows the air duct assembly 20 to rotate relative to the housing 10 while the housing 10 can guide the air duct assembly 20. When the driving device 41 drives the air duct assembly 20 to rotate, the sliding rod on the air duct assembly 20 slides along the sliding groove, causing the air duct assembly 20 to rotate relative to the housing 10. This allows the air outlet 23 to blow air in both vertical and horizontal directions, expanding the air outlet range of the evaporator.

[0042] In the first embodiment of the present invention, the first mating part 42 is a slide rod, and the second mating part 43 is a slide groove. Both the slide groove and the slide rod are arc-shaped structures. With the above arrangement, the slide groove on the air duct assembly 20 is sleeved on the slide rod inside the outer shell 10 and is slidably arranged along the extension direction of the slide rod. This allows the air duct assembly 20 to rotate relative to the outer shell 10 while the outer shell 10 can also guide the air duct assembly 20. When the driving device 41 drives the air duct assembly 20 to rotate, the slide groove on the air duct assembly 20 slides on the slide rod, causing the air duct assembly 20 to rotate relative to the outer shell 10. As a result, the air outlet 23 blows air in the vertical and horizontal directions, expanding the air outlet range of the evaporator.

[0043] like Figure 5 As shown, the machine head also includes a transmission assembly 40, which is located inside the housing 10. The drive device 41 drives the air duct assembly 20 to rotate via the transmission assembly 40. There may be one transmission assembly 40; or there may be two transmission assemblies 40, each located on one side of the second mating part 43. In the above configuration, when there is one transmission assembly 40, it is positioned on the air duct assembly 20 on one side of the second mating part 43. The drive device 41 is driven by the transmission assembly 40, allowing the air duct assembly 20 to rotate relative to the housing 10, and the air outlet 23 of the air duct assembly 20 can rotate up and down to blow air. When there are two transmission assemblies 40, they are respectively positioned on the air duct assembly 20 on both sides of the second mating part 43. The two drive devices 41 are driven by their respective transmission assemblies 40, allowing the air duct assembly 20 to rotate up and down, thereby increasing the power of the drive device 41.

[0044] Specifically, the drive unit 41 has a drive shaft, and the transmission assembly 40 includes a gear 44 and a rack 45, with the gear 44 connected to the drive shaft. The rack 45 is disposed on the outer peripheral surface 25 of the air duct assembly 20 and meshes with the gear 44. The extending direction of the rack 45 is consistent with the circumferential direction of the outer peripheral surface 25. In this configuration, the rack 45 is disposed on the outer peripheral surface 25 of the air duct assembly 20 along its extending direction, and the gear 44 meshes with the rack 45 to drive the gear 44 to rotate via the drive unit 41. When the gear 44 rotates, it meshes with the rack 45, causing the air duct assembly 20 to rotate relative to the housing 10.

[0045] It should be noted that the type of transmission assembly 40 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the transmission assembly 40 can be a gear and gear transmission assembly, a gear chain transmission assembly, or a worm gear transmission assembly.

[0046] like Figure 7As shown, the air conditioning unit includes at least two baffles 24, both of which are connected to the air duct assembly 20 and located on both sides of the air outlet 23. The air outlet 23 has a first air outlet direction and a second air outlet direction arranged at an angle. When the air outlet 23 discharges air along the first air outlet direction, the air outlet 23 communicates with a portion of the opening 12, and one baffle 24 blocks the other portion of the opening 12. When the air outlet 23 discharges air along the second air outlet direction, the air outlet 23 communicates with a portion of the opening 12, and the other baffle 24 blocks the other portion of the opening 12. In this way, regardless of whether the air cooler discharges air horizontally or vertically, the above arrangement ensures that the baffles 24 can block part of the opening 12, thereby preventing the internal structure of the air conditioning unit from being exposed and affecting the aesthetics of the air cooler.

[0047] In the above configuration, at least two baffles 24 are provided with barbs, and the air duct assembly 20 is also provided with barbs. The two barbs are interlocked, and the air duct assembly 20 can drive the baffles 24 to move synchronously. In this embodiment, the air duct assembly 20 is provided with two baffles 24, namely a first baffle and a second baffle. The first baffle and the second baffle are respectively disposed on both sides of the air outlet 23 of the air duct assembly 20. The first air outlet direction is that the air outlet 23 of the air duct assembly 20 blows air in a horizontal direction, and the second air outlet direction is that the air outlet 23 of the air duct assembly 20 blows air in a vertical direction. When the air duct assembly 20 blows air in the first air outlet direction, the air outlet 23 is connected to a part of the opening 12 and blows air, and the first baffle is used to block the other part of the opening 12. When the air duct assembly 20 blows air in the second air outlet direction, the air outlet 23 is connected to a part of the opening 12 and blows air, and the second baffle is used to block the other part of the opening 12. So that when the air duct assembly 20 rotates up and down, the first baffle and the second baffle can cover the internal structure of the outer shell 10 to achieve an aesthetic effect.

[0048] like Figure 8 and Figure 9 As shown, the outer casing 10 also has at least two sets of guide portions 13 spaced circumferentially along the air duct assembly 20. Each set of guide portions 13 corresponds to at least two baffles 24. Each set of guide portions 13 includes at least one guide structure 131, which includes a bent section. Each baffle 24 overlaps the bent section of its corresponding guide portion 13 to slide along the bent section. In this configuration, the guide structure 131 is an L-shaped plate, with one end connected to the inner wall of the outer casing 10. The first baffle and the second baffle overlap the bent section at the other end of their respective guide structures 131. When the air outlet 23 of the air duct assembly 20 rotates from the first air outlet direction to the second air outlet direction, the first baffle and the second baffle slide along the bent section, thereby blocking the opening 12.

[0049] Optionally, a bracket 14 is also provided inside the outer casing 10, and the evaporator 30 is mounted on the bracket 14. Optionally, there are multiple brackets 14, and multiple brackets 14 are arranged one-to-one with multiple evaporators 30, with each evaporator 30 mounted on its corresponding bracket 14. In the above arrangement, the bracket 14 is located below the corresponding air inlet 11 inside the outer casing 10, and each evaporator 30 is mounted on its corresponding bracket 14 for support, so that each evaporator 30 is arranged one-to-one with each air inlet 11. At the same time, the above arrangement makes the insertion and installation of the evaporator 30 easier and simpler, and reduces the difficulty of disassembling and assembling the evaporator 30.

[0050] Specifically, the outer casing 10 includes a first sub-shell 15 and a second sub-shell. The first sub-shell 15 includes an arc-shaped surrounding plate 151 and a first flat plate 152. The arc-shaped surrounding plate 151 is disposed on the surface of the first flat plate 152 and has a notch. The second sub-shell includes an arc-shaped plate and a second flat plate. The arc-shaped plate is disposed on the surface of the second flat plate, and the arc-shaped plate and the notch surround each other to form an opening 12. Both the second flat plate and the arc-shaped plate are connected to the arc-shaped surrounding plate 151. The first flat plate 152 is provided with at least one air inlet 11, and the second flat plate is provided with at least one other air inlet 11. In the above configuration, the air duct assembly 20 and at least one evaporator 30 are disposed within the first sub-shell 15, and the air outlet 23 of the air duct assembly 20 communicates with a portion of the notch. The first baffle of the air duct assembly 20 blocks the other portion of the notch. The first plate 152 has at least one air inlet 11. At least one evaporator 30 is mounted on the first plate 152 and is disposed corresponding to the air inlet 11. The guide portion 13 is disposed on the arc-shaped enclosure 151, and each baffle 24 on the air duct assembly 20 overlaps with the guide portion 13. At least one other evaporator 30 is disposed on the second plate of the second sub-shell, and the second plate has at least one other air inlet 11. At least one other evaporator 30 is mounted on the second plate and is disposed corresponding to the air inlet 11.

[0051] Optionally, the air duct structure 21 includes an air duct housing 211 and a mounting bracket 212. The air duct structure 21 has an interconnected mounting port 2112 and an arc-shaped air duct 2113. The air outlet end of the arc-shaped air duct 2113 is an air outlet 23. The mounting bracket 212 is connected to the air duct housing 211 and is disposed at the mounting port 2112. The fan 22 is disposed on the mounting bracket 212. The rack 45 and the baffle 24 are both disposed on the outer peripheral surface of the air duct housing 211. In the above configuration, the mounting port 2112, the arc-shaped air duct 2113, and the air outlet 23 are connected in sequence. The fan 22 is a centrifugal fan. The characteristics of a centrifugal fan are that it can directly draw in air from both sides and discharge air from the front, and it has a high air delivery efficiency. The fan 22 is mounted on the mounting bracket 212 on the air duct structure 21 and is located at the mounting port 2112. By driving the fan 22, the cold air generated by at least two evaporators 30 flows into the arc-shaped air duct 2113 through the mounting port 2112. Then, the cold air in the arc-shaped air duct 2113 is blown out through the air outlet 23. At this time, by coordinating the up-and-down rotation of the air duct assembly 20 and the left-and-right rotation of the outer casing 10, the air cooler can rotate up and down and left and right and blow air, which improves the humidification and cooling effect of the air cooler and provides users with a comfortable user experience, thus solving the problem that the air outlet method of the air cooler in the prior art cannot meet the user's needs.

[0052] Applying the technical solution of the present invention, a cooling fan is also provided, the cooling fan including a fan head, the fan head being disposed on the top of the cooling fan; wherein, the fan head is the aforementioned fan head.

[0053] like Figure 1 and Figure 2 As shown, the evaporator also includes a water tank 60. Each evaporator 30 includes a buffer structure and a wet curtain structure. The buffer structure has a water inlet 32, a water storage tank 31, and multiple water outlets 33. The water inlet 32 ​​is connected to each water outlet 33 through the water storage tank 31 and is also connected to the water tank 60. The wet curtain structure is connected to the buffer structure and is located below the buffer structure. Liquid flowing from each water outlet 33 flows to the wet curtain structure to wet it. The multiple water outlets 33 are spaced apart along the length and / or width of the wet curtain structure. A return water hole 16 is provided at the bottom of the outer casing 10 to allow the liquid flowing from the wet curtain structure to return to the water tank 60. In the above configuration, the water inlet 32 ​​is connected to the water tank 60 so that the water in the water tank 60 is pumped to the water storage tank 31 by the water pump. Multiple water outlets 33 are used to spray water evenly on the wet curtain structure to wet the wet curtain structure. At the same time, the water flowing out from the evaporator 30 flows to the bottom of the outer shell 10 so that it flows into the water tank 60 through the return water hole 16, thereby forming a water circulation.

[0054] Specifically, the evaporator also includes an oscillating assembly 70, a support rod 50, and a water tank 60 connected in sequence. The outer casing 10 is connected to the support rod 50 via the oscillating assembly 70. At least a portion of the oscillating assembly 70 is movably configured to drive the outer casing 10 to rotate around a preset axis. In this configuration, the oscillating assembly 70 is fixedly connected to the bottom of the outer casing 10 and movably connected to the support rod 50. The oscillating assembly 70 drives the outer casing 10 to rotate left and right, causing the air outlet 23 of the air duct assembly 20 to rotate left and right for airflow. Simultaneously, it coordinates with the up-and-down rotation of the air duct assembly 20 to achieve both up-and-down and left-and-right rotation of the evaporator for airflow, improving the evaporator's cooling performance and providing a comfortable user experience.

[0055] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0056] The air cooler includes a housing, an air duct assembly, and at least one evaporator. The housing has an air inlet and an opening, with at least one air inlet. The air duct assembly is movably disposed within the housing and includes an air duct structure and a fan disposed within the air duct structure. The air duct structure has an air outlet, and the air inlet communicates with the opening through the air outlet. At least one evaporator is disposed within the housing, with each evaporator corresponding to at least one air inlet, and each evaporator is located between its corresponding air inlet and the air duct assembly. The position of the air outlet is adjustable. With this configuration, when the fan located within the air duct structure is activated, air enters through at least one air inlet on the housing. The air entering through the air inlet flows through the corresponding at least one evaporator, which cools and condenses the air, forming cold air. Driven by the fan, the cold air flows into the air duct structure and is blown out through the air outlet of the air duct structure, thus enabling the air cooler to draw air in from the side. Meanwhile, when it is necessary to adjust the airflow direction of the air cooler, the air duct component can be moved (e.g., rotated) relative to the outer casing to adjust the airflow direction of the air outlet, thereby achieving the purpose of the air cooler taking in air from the side and blowing air from multiple angles. This solves the problem that the airflow method of the air cooler in the prior art cannot meet the user's needs and improves the user experience.

[0057] 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. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0058] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. 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. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. 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 figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0059] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0060] 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.

[0061] 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 should not be construed as limiting the scope of protection of this invention.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
