Description

Technical Field

[0001] This invention relates to the field of valve and pump technology, and in particular to an integrated valve and pump. Background Technology

[0002] With the increasing popularity of automobiles, people not only have higher requirements for car brands, safety, and quality, but also place greater emphasis on driving comfort. To reduce fatigue caused by long-distance driving, car seats are usually equipped with lumbar supports, among which pneumatic lumbar supports are convenient to use, quick to adjust, highly reliable, and have received positive user feedback.

[0003] The normal operation of a pneumatic lumbar support depends on the coordinated work of an air pump and an air valve. Together, they constitute the core functional components of the pneumatic lumbar support, and their performance directly determines the adjustment effect and user experience of the lumbar support.

[0004] However, existing equipment can only perform the functions of inflating and deflating the lumbar support, and cannot integrate an air extraction function. When air extraction is required for the pneumatic lumbar support, an independent air extraction device must be configured for the pneumatic lumbar support system. This not only increases the overall installation complexity of the equipment and raises production and usage costs, but also reduces the convenience of user operation due to the need for multiple devices to operate in tandem, making it difficult to meet the technological trend of automotive comfort configurations towards integration and high efficiency. Summary of the Invention

[0005] To address the shortcomings of the prior art, this invention provides an integrated valve pump that can flexibly switch between three working states: inflation, evacuation, and deflation. When evacuation of the gas-using unit is required, there is no need to configure an additional independent evacuation device, thus reducing the overall installation complexity of the equipment.

[0006] The technical effects to be achieved by this invention are realized through the following technical solutions: This invention provides an integrated valve pump, comprising: An air pump includes a gas distribution assembly and a pump body. The gas distribution assembly includes a first distribution chamber and a second distribution chamber that are isolated from each other, and the gas in the first distribution chamber is unidirectionally conducted to the second distribution chamber through the pump body. A first solenoid valve has a first connecting port, a first air inlet, and a second air inlet that are mutually connected. The first solenoid valve has an inflation state where the second air inlet is blocked to allow the first air inlet and the first connecting port to be open, and an air extraction state where the first air inlet is blocked to allow the second air inlet and the first connecting port to be open; and The second solenoid valve has a second connecting port, an air inlet, and an air vent that are interconnected. The second solenoid valve has an air-filling state in which the air vent is blocked to allow the air inlet and the second connecting port to be connected, and an air-evacuating state in which the air inlet is blocked to allow the air vent and the second connecting port to be connected. The second air inlet and the air filling port are both connected to the air-using unit; the first distribution cavity is connected to the first communication port, and the second distribution cavity is connected to the second communication port.

[0007] In some implementations, the first solenoid valve includes a first valve body and a first valve core. The first valve body has a first conducting chamber. The first connecting port, the first air inlet, and the second air inlet are located in the first valve body and are respectively connected to the first conducting chamber. The first valve core is disposed in the first valve body and is used to block the second air inlet or the first air inlet.

[0008] In this implementation, when the first valve core is in the position of blocking the second air inlet, the first solenoid valve is in the charging state; when the first valve core is in the position of opening the second air inlet or blocking the first air inlet, the first solenoid valve is in the evacuation or degassing state.

[0009] In some implementations, the second solenoid valve includes a second valve body and a second valve core. The second valve body has a second conduction chamber. The second communication port, the air inlet, and the air outlet are located in the second valve body and are respectively connected to the second conduction chamber. The second valve core is disposed in the second valve body and is used to block the air outlet or the air inlet.

[0010] In this implementation, when the second valve core is in the position of blocking the vent, the second solenoid valve is in the inflation state; when the second valve core is in the position of blocking the inflation port, the second solenoid valve is in the evacuation or deflation state.

[0011] In some implementations, the first connection port is connected to the first distribution cavity through a first flow channel, and the second connection port is connected to the second distribution cavity through a second flow channel.

[0012] In some implementations, the integrated valve pump also includes a three-way valve, which has a first interface, a second interface, and a third interface that are interconnected. The second air inlet is connected to the first interface, the air filling port is connected to the second interface, and the third interface is connected to the air-using unit.

[0013] In this implementation, during inflation, the gas enters the gas-using unit sequentially through the inflation port, the second interface, and the third interface; during evacuation or deflation, the gas enters the first conductive chamber sequentially through the third interface, the first interface, and the second air inlet, and then enters the first conductive chamber through the second air inlet, thus achieving evacuation or deflation along the evacuation path.

[0014] In some implementations, the first valve body includes a first housing, a second housing, and a third housing connected in sequence. The first housing, the second housing, and the third housing together have the first conduction chamber. The first air inlet is located on the second housing, and the first connecting port and the second air inlet are respectively located on the third housing.

[0015] In some implementations, the first solenoid valve further includes a first coil wound around the outer periphery of the first housing.

[0016] In some implementations, the second valve body includes a first outer shell, a second outer shell, and a third outer shell connected in sequence. The first outer shell, the second outer shell, and the third outer shell together have a second conductive chamber. The air inlet is located on the second outer shell, and the second connecting port and the air vent are respectively located on the third outer shell.

[0017] In some implementations, the second solenoid valve further includes a second coil wound around the outer periphery of the first housing.

[0018] In some implementations, the gas distribution assembly includes a valve seat and a top cover, the top cover being sealed to the valve seat, and the top cover having a ridge inside that is sealed to the valve seat. The first distribution cavity and the second distribution cavity are formed between the top cover and the valve seat and are isolated from each other by the ridge.

[0019] In this implementation, the ridge serves as a key isolation structure between the top cover and the valve seat, directly dividing the space enclosed by the top cover and the valve seat into a first distribution cavity and a second distribution cavity. Furthermore, the ridge forms a physical rigid isolation barrier through a sealing connection with the valve seat.

[0020] In some implementations, the pump body includes a deformable pump chamber, and the valve seat is provided with a first check valve and a second check valve, and the pump chamber simultaneously seals and covers the first check valve and the second check valve.

[0021] In this implementation, the first check valve and the second check valve integrated on the valve seat, together with the contraction or expansion action of the deformable pump chamber, form a unidirectional gas flow path.

[0022] In summary, the present invention has at least the following advantages: The integrated valve pump provided by this invention has a gas distribution assembly with a first distribution chamber and a second distribution chamber that are isolated from each other. The first distribution chamber is connected to a first solenoid valve, and the second distribution chamber is connected to a second solenoid valve. Gas in the first distribution chamber can be unidirectionally guided to the second distribution chamber through the pump body. Through the coordinated control of the first solenoid valve, the second solenoid valve, and the air pump, the three working states of inflation, deflation, and evacuation can be flexibly switched. When it is necessary to evacuate the gas-using unit, there is no need to configure an additional independent evacuation device, which reduces the overall installation complexity of the equipment and makes the operation more convenient for users.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0026] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0027] Example 1: Please see the appendix Figure 1 ~Appendix Figure 6 The integrated valve pump of the present invention includes an air pump 100, a first solenoid valve 200 and a second solenoid valve 300.

[0028] In this regard, please combine Figure 2 , Figure 4 and Figure 5 , Figure 2 The diagram illustrates the structural relationship between the air pump 100, the first solenoid valve 200, and the second solenoid valve 300 in an embodiment of the present invention. Figure 4 and Figure 5The diagram illustrates the structural relationship between the first solenoid valve 200 and the second solenoid valve 300 in an embodiment of the present invention. Specifically, the air pump 100 includes a gas distribution assembly 110 and a pump body 120. The gas distribution assembly 110 includes a first distribution chamber 111 and a second distribution chamber 112 that are isolated from each other, and the gas in the first distribution chamber 111 is unidirectionally guided to the second distribution chamber 112 through the pump body 120. The first solenoid valve 200 has a first connecting port 201, a first air inlet 202, and a second air inlet 203 that are interconnected. The first solenoid valve 200 has a charging state in which the second air inlet 203 is blocked to allow the first air inlet 202 and the first connecting port 201 to be open, and a pumping state in which the first air inlet 202 is blocked to allow the second air inlet 203 and the first connecting port 201 to be open. The second solenoid valve 300 has a second connecting port 301, an inflation port 302, and an venting port 303 that are interconnected. The second solenoid valve 300 has an inflation state where the venting port 303 is blocked, allowing the inflation port 302 and the second connecting port 301 to be connected, and a venting state where the inflation port 302 is blocked, allowing the venting port 303 and the second connecting port 301 to be connected. The second air inlet 203 and the inflation port 302 are both connected to the air-using unit; the first distribution chamber 111 is connected to the first connecting port 201, and the second distribution chamber 112 is connected to the second connecting port 301.

[0029] In this embodiment, the integrated valve pump can be compatible with inflation, deflation, and venting functions. Specifically, the first solenoid valve 200 further includes a first coil 240 and a first elastic element. The first coil 240 is wound around the outer periphery of the first valve body 210. The opposite ends of the first elastic element abut against the inner walls of the first valve core 220 and the first valve body 210, respectively, so that the first valve core 220 normally blocks the second air inlet 203. When the first coil 240 is energized, the first valve core 220 overcomes the elastic force of the first elastic element, thereby opening the second air inlet 203. The second solenoid valve 300 further includes a second coil 340 and a second elastic element. The second coil 340 is wound around the outer periphery of the second valve body 310. The opposite ends of the second elastic element abut against the inner walls of the second valve core 320 and the second valve body 310, respectively, so that the second valve core 320 normally blocks the vent 303. When the second coil 340 is energized, the second valve core 320 overcomes the elastic force of the second elastic element, thereby opening the vent 303.

[0030] When the integrated valve pump is in the inflation state, the first valve core 220 blocks the second air inlet 203 to make the first air inlet 202 and the first connecting port 201 connected, and the second valve core 320 blocks the vent 303 to make the inflation port 302 and the second connecting port 301 connected. Gas enters the first conducting chamber 211 from the first air inlet 202 of the first solenoid valve 200, and enters the first distribution chamber 111 in sequence along the gap between the first valve body 210 and the first valve core 220 and the first connecting port 201. Then, the gas is pumped into the second distribution chamber 112 by the pump body 120. The gas enters the second conducting chamber 311 through the second connecting port 301, and flows to the inflation port 302 along the gap between the second valve body 310 and the second valve core 320, thereby realizing the inflation of the gas-using unit.

[0031] When the integrated valve pump is in the pumping state, the first valve core 220 blocks the first air inlet 202 to allow the second air inlet 203 and the first connecting port 201 to be open, and the second valve core 320 blocks the air filling port 302 to allow the air vent 303 and the second connecting port 301 to be open. Gas enters the first conducting chamber 211 from the second air inlet 203 of the first solenoid valve 200, enters the first distribution chamber 111 through the first connecting port 201, and is pumped into the second distribution chamber 112 by the pump body 120. Gas enters the second conducting chamber 311 through the second connecting port 301 and is discharged through the air vent 303, thereby using the gas unit to achieve pumping.

[0032] When the integrated valve pump is in the venting state, the first valve core 220 blocks the first air inlet 202 to allow the second air inlet 203 and the first connecting port 201 to be open, and the second valve core 320 blocks the air filling port 302 to allow the venting port 303 and the second connecting port 301 to be open. Gas enters the first conducting chamber 211 from the second air inlet 203 of the first solenoid valve 200, enters the first distribution chamber 111 and the second distribution chamber 112 in sequence through the first connecting port 201, and then enters the second conducting chamber 311 from the second connecting port 301, and is discharged through the venting port 303, thereby achieving venting.

[0033] It should be noted that when the integrated valve pump is in the venting state, the pump body 120 does not participate in the operation. The gas is slowly discharged through the same path as when it is in the pumping state to achieve venting. There is no need to add an extra venting channel, which simplifies the structure and achieves slow gas discharge, avoiding a sudden drop in lumbar support force, and taking into account both venting reliability and user comfort and safety.

[0034] The aforementioned integrated valve pump has a gas distribution assembly 110 with a first distribution chamber 111 and a second distribution chamber 112 that are isolated from each other. The first distribution chamber 111 is connected to the first solenoid valve 200, and the second distribution chamber 112 is connected to the second solenoid valve 300. Gas in the first distribution chamber 111 can be unidirectionally guided to the second distribution chamber 112 through the pump body 120. Through the coordinated control of the first solenoid valve 200, the second solenoid valve 300, and the air pump 100, the three working states of inflation, deflation, and evacuation can be flexibly switched. When it is necessary to evacuate the gas-using unit, there is no need to configure an additional independent evacuation device, which reduces the overall installation complexity of the equipment and makes the operation more convenient for users.

[0035] Example 2: The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the integrated valve pump of the present invention. Please refer to the appendix. Figure 3 ~Appendix Figure 6 .

[0036] Please see below. Figure 4 , Figure 4 The diagram illustrates the structural relationship between the first valve body 210 and the first valve core 220 in an embodiment of the present invention. The first solenoid valve 200 includes a first valve body 210 and a first valve core 220. The first valve body 210 has a first conducting chamber 211. A first connecting port 201, a first air inlet 202, and a second air inlet 203 are opened in the first valve body 210 and are respectively connected to the first conducting chamber 211. The first valve core 220 is disposed in the first valve body 210 and is used to block the second air inlet 203 or the first air inlet 202.

[0037] In this embodiment, when the first valve core 220 is in the position of blocking the second air inlet 203, the first solenoid valve 200 is in the inflation state. In this inflation state, the second air inlet 203 is closed, while the first air inlet 202 and the first connecting port 201 are connected. When the first valve core 220 is in the position of opening the second air inlet 203 or blocking the first air inlet 202, the first solenoid valve 200 is in the air extraction or air release state. In this state, the first air inlet 202 is blocked, while the second air inlet 203 and the first connecting port 201 are connected.

[0038] In some preferred embodiments, please refer to Figure 5 , Figure 5The diagram illustrates the structural relationship between the second valve body 310 and the second valve core 320 in an embodiment of the present invention. The second solenoid valve 300 includes a second valve body 310 and a second valve core 320. The second valve body 310 has a second conducting chamber 311. A second connecting port 301, an inflation port 302, and an venting port 303 are opened in the second valve body 310 and are respectively connected to the second conducting chamber 311. The second valve core 320 is disposed in the second valve body 310 and is used to block the venting port 303 or the inflation port 302. When the second valve core 320 is in the position of blocking the vent 303, the second solenoid valve 300 is in the inflation state. In this inflation state, the vent 303 is closed, while the inflation port 302 and the second connecting port 301 are connected. When the second valve core 320 is in the position of blocking the inflation port 302, the second solenoid valve 300 is in the evacuation or deflation state. In this state, the inflation port 302 is blocked, while the vent 303 and the second connecting port 301 are connected.

[0039] In some preferred embodiments, the first connecting port 201 is connected to the first distribution chamber 111 through the first flow channel 230, and the second connecting port 301 is connected to the second distribution chamber 112 through the second flow channel 330. When the integrated valve pump is in the inflation state, the gas passes sequentially through the air inlet, the gap between the first valve body 210 and the first valve core 220, and the first connecting port 201. It then enters the first flow channel 230 through the first connecting port 201, thereby entering the first distribution chamber 111. The gas is then pumped into the second distribution chamber 112 by the pump body 120. The gas is output from the second distribution chamber 112 and flows along the second flow channel 330 to the interior of the second conducting chamber 311. It then flows along the gap between the second valve body 310 and the second valve core 320 to the inflation port 302, thereby inflating the gas-using unit.

[0040] When the integrated valve pump is in the pumping state, the gas passes through the second inlet 203 and the first connecting port 201 in sequence, enters the first flow channel 230 through the first connecting port 201, and then enters the first distribution chamber 111. The gas is then pumped into the second distribution chamber 112 by the pump body 120. The gas is output from the second distribution chamber 112 and flows along the second flow channel 330 to the inside of the second guide chamber 311, and is discharged through the vent 303, thereby using the gas unit to achieve pumping.

[0041] In some preferred embodiments, the integrated valve pump further includes a three-way valve 400, which has a first interface 401, a second interface 402, and a third interface 403 that are interconnected. A second air inlet 203 is connected to the first interface 401, an air filling port 302 is connected to the second interface 402, and the third interface 403 is connected to the air-using unit. During inflation, gas enters the air-using unit sequentially through the air filling port 302, the second interface 402, and the third interface 403. During evacuation or deflation, gas sequentially passes through the third interface 403, the first interface 401, and the second air inlet 203, and enters the first conductive chamber 211 through the second air inlet 203, achieving evacuation or deflation along the evacuation path.

[0042] In some preferred embodiments, the first valve body 210 includes a first housing 212, a second housing 213, and a third housing 214 connected in sequence. The first housing 212, the second housing 213, and the third housing 214 share a first guiding chamber 211. A first air inlet 202 is located on the second housing 213, and a first connecting port 201 and a second air inlet 203 are respectively located on the third housing 214. By assigning the first air inlet 202, the first connecting port 201, and the second air inlet 203 to specific housings, a precise correspondence between the interface and the function is achieved. The second housing 213 is used to receive external gas, and the third housing 214 is used to connect the air pump 100 and the gas-using unit. Together with the first guiding chamber 211 formed by the first housing 212, the second housing 213, and the third housing 214, a clear flow direction is formed between external air intake, the first guiding chamber 211, and the air pump 100 or the gas-using unit. This avoids path crossing or interference caused by concentrated interface locations, further ensuring the accuracy of gas flow during inflation and deflation.

[0043] In some preferred embodiments, the first solenoid valve 200 further includes a first coil 240 wound around the outer periphery of the first housing 212. When the first coil 240 is energized, it drives the first valve core 220 to overcome the force of the first elastic element, thereby opening the second air inlet 203 and ensuring reliable air supply to the air-using unit. Furthermore, the first coil 240's winding around the outer periphery of the first housing 212 fully utilizes the external space of the first housing 212, avoiding interference with the first air inlet 202, the first connecting port 201, and the second air inlet 203, while also making the overall structure more compact.

[0044] In some preferred embodiments, the second valve body 310 includes a first outer shell 312, a second outer shell 313, and a third outer shell 314 connected in sequence. The first outer shell 312, the second outer shell 313, and the third outer shell 314 together have a second conductive chamber 311. An air inlet 302 is opened on the second outer shell 313, and a second connecting port 301 and an air vent 303 are respectively opened on the third outer shell 314. By assigning the inflation port 302, the second connecting port 301, and the vent port 303 to specific housings, a clear correspondence between the interface and function is achieved. The second housing 313 is used to receive the gas delivered by the air pump 100, and the third housing 314 is used to connect the air pump 100 with the external exhaust channel. Together with the first housing 312, the second housing 313, and the third housing 314, a clear path is formed for the gas from the air pump 100, the second housing 311, and the gas-using unit, or the gas from the gas-using unit, the second housing 311, and the external vent. This avoids airflow crossover and interference caused by concentrated interface openings, ensuring that the gas is accurately delivered to the gas-using unit during inflation and that the gas is directionally discharged during deflation, thus ensuring the precise control of the gas by the second solenoid valve 300.

[0045] In some more preferred embodiments, the second solenoid valve 300 further includes a second coil 340 wound around the outer periphery of the first housing 312. When the second coil 340 is energized, it drives the second valve core 320 to overcome the force of the second elastic element, thereby opening the vent 303 and ensuring the reliability of evacuating or venting the gas-using unit. Furthermore, the second coil 340 being wound around the outer periphery of the first housing 312 fully utilizes the external space of the first housing 312, avoiding interference with the inflation port 302, the second communication port 301, and the vent 303, while also making the overall structure more compact.

[0046] Example 3: The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the integrated valve pump of the present invention. Please refer to the appendix. Figure 6 ~Appendix Figure 7 .

[0047] The gas distribution assembly 110 includes a valve seat 113 and an upper cover 114. The upper cover 114 is sealed to the valve seat 113, and the upper cover 114 has a ridge 115 sealed to the valve seat 113 inside. The first distribution chamber 111 and the second distribution chamber 112 are formed between the upper cover 114 and the valve seat 113 and are isolated from each other by the ridge 115.

[0048] In this embodiment, the ridge 115 serves as a key isolation structure between the upper cover 114 and the valve seat 113, directly dividing the space enclosed by the upper cover 114 and the valve seat 113 into a first distribution chamber 111 and a second distribution chamber 112. Furthermore, the ridge 115 and the valve seat 113 are sealed together, forming a physical rigid isolation barrier. This prevents cross-flow of gas between the two chambers due to pressure differences, such as high pressure in the first distribution chamber 111 and low pressure in the second distribution chamber 112 during inflation. It ensures that the gas output from the air pump 100 is accurately delivered to the target distribution chamber, or that the gas to be discharged flows only through the designated distribution chamber to the vent 303. This structural design guarantees the accuracy of gas distribution and avoids problems such as slow inflation or inability to maintain pressure in pneumatic actuators, such as seat airbags, caused by cross-flow of gas.

[0049] In some preferred embodiments, the pump body 120 includes a deformable pump chamber 121, and the valve seat 113 is respectively provided with a first one-way valve 1131 and a second one-way valve 1132. The pump chamber 121 simultaneously seals and covers the first one-way valve 1131 and the second one-way valve 1132. The first one-way valve 1131 and the second one-way valve 1132 integrated on the valve seat 113 cooperate with the contraction or expansion of the deformable pump chamber 121 to form a one-way gas flow path. When the pump chamber 121 expands, a negative pressure is generated inside, the first one-way valve 1131 opens and the second one-way valve 1132 closes, and gas is drawn into the pump chamber 121 from the first distribution chamber 111 through the first one-way valve 1131; when the pump chamber 121 contracts, a positive pressure is generated inside, the second one-way valve 1132 opens and the first one-way valve 1131 closes, and gas in the pump chamber 121 is forced into the second distribution chamber 112 through the second one-way valve 1132. The one-way conduction characteristic of the dual one-way valves structurally prevents reverse gas flow, ensuring that during inflation, gas sequentially enters the first distribution chamber 111, the pump chamber 121, the second distribution chamber 112, and the gas-using unit, and during evacuation, gas is precisely extracted along the gas-using unit, the first distribution chamber 111, the pump chamber 121, and the second distribution chamber 112, ensuring that the airflow paths of the two functions do not interfere with each other or flow backward.

[0050] The integrated valve pump of the present invention has a gas distribution assembly 110 with a first distribution chamber 111 and a second distribution chamber 112 that are isolated from each other. The first distribution chamber 111 is connected to a first solenoid valve 200, and the second distribution chamber 112 is connected to a second solenoid valve 300. Gas in the first distribution chamber 111 can be unidirectionally guided to the second distribution chamber 112 through the pump body 120. Through the coordinated control of the first solenoid valve 200, the second solenoid valve 300 and the air pump 100, the three working states of inflation, deflation and evacuation can be flexibly switched. When it is necessary to perform evacuation operation on the gas-using unit, there is no need to configure an additional independent evacuation device, which reduces the overall installation complexity of the equipment and makes the operation more convenient for users.

[0051] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 or an electrical connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and 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 of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0054] In this invention, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0055] Although the description of the invention has been given in conjunction with the specific embodiments described above, it will be apparent to those skilled in the art that many substitutions, modifications, and variations can be made based on the foregoing. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
