Description

Technical Field

[0001] This application relates to the field of air source water heater technology, and in particular to an air source water heater with a drainage structure. Background Technology

[0002] In modern homes and commercial facilities, integrated air source heat pump water heaters are widely used due to their high efficiency and energy saving. These heaters heat water by utilizing heat from the air, reducing reliance on traditional energy sources and lowering energy consumption and operating costs. The structure of an integrated air source heat pump water heater typically consists of two main parts: the upper outdoor unit and the lower water tank. The outdoor unit absorbs heat from the air and circulates it via a heat pump, while the water tank stores the heated water.

[0003] However, in actual operation, condensation will occur in the outdoor unit components during the heat pump cycle. This is because during the heat pump cycle, the refrigerant absorbs a large amount of heat when evaporating in the evaporator and releases heat when condensing in the condenser; the surface temperature of the outdoor unit components decreases, and water vapor in the air condenses into water droplets when it comes into contact with the cold surfaces, forming condensation. This condensation must be effectively drained to prevent water accumulation and damage to the equipment.

[0004] However, existing drainage structures suffer from poor drainage, leading to condensate buildup inside the equipment and affecting its performance and lifespan. Especially in low-temperature environments, condensate is prone to freezing, causing blockages in the drainage channels, further exacerbating the drainage problem, affecting drainage efficiency, and potentially damaging the equipment. This not only affects the operating efficiency of the air source water heater but also increases maintenance costs and user inconvenience. Summary of the Invention

[0005] In order to improve the shortcomings of existing air source water heaters, such as poor drainage and easy freezing and blockage of drainage channels in low-temperature environments, this application provides an air source water heater with a drainage structure.

[0006] The air source heat pump water heater with a drainage structure provided in this application adopts the following technical solution: An air source heat pump water heater with a drainage structure includes a housing support, a water tank disposed within the housing support, a condensing device disposed on the water tank, an evaporating device disposed above the water tank, an expansion valve disposed between the condensing device and the evaporating device, a compressor, and a drainage device disposed between the evaporating device and the water tank. The drainage device includes a drainage support base, a water guide base located below the drainage support base, a rotary drive assembly located at the bottom of the water guide base, a rotary heating plate located at the output end of the rotary drive assembly and inserted into the water guide base, a temperature sensor located on the rotary heating plate and electrically connected to the rotary heating plate, and an active drainage mechanism for connecting the interior and exterior spaces of the water guide base; when the temperature on the rotary heating plate is lower than a preset temperature, the temperature sensor triggers the rotary heating plate to heat up.

[0007] By adopting the above technical solution, the condensate on the evaporator drips onto the rotating heating plate through the drain support base. The rotating drive component drives the rotating heating plate to rotate, and the centrifugal force of the rotating heating plate throws the condensate into the water guide base. The active drainage mechanism then discharges the condensate to the outside of the water guide base, improving the condensate discharge rate and reducing water accumulation. When the temperature on the rotating heating plate is lower than the preset temperature, the temperature sensor triggers the rotating heating plate to heat up. This allows the rotating heating plate to heat the condensate while throwing it out, preventing the condensate from freezing and clogging. The active drainage mechanism in this application further improves drainage efficiency, avoids the freezing and poor drainage problems existing in the drainage structure of traditional air source water heaters, enhances the stability and reliability of the integrated air source water heater in low-temperature environments, and improves the service life and user satisfaction of the integrated air source water heater.

[0008] Preferably, the rotating heating plate includes a heating plate body, a water guide portion disposed on the heating plate body, and a heating component inserted into the water guide portion; the heating component is electrically connected to the temperature sensor, and when the temperature on the rotating heating plate is lower than a preset temperature, the temperature sensor triggers the heating component to heat.

[0009] By adopting the above technical solution, when the rotating heating plate rotates, the condensate is guided and thrown out through the water guide section. Through the electrical connection between the heating component and the temperature sensor, when the temperature on the rotating heating plate is lower than the preset temperature, the temperature sensor triggers the heating component to heat. This not only ensures the effective discharge of condensate and prevents freezing in low-temperature environments, but also improves the discharge efficiency of condensate and enhances the operating efficiency and stability of the air source water heater.

[0010] Preferably, a plurality of the water guide sections are arranged in a circumferential array along the center of the heating plate body, and the width of the water guide sections gradually decreases along the direction close to the drainage support base.

[0011] By adopting the above technical solution, multiple water guide sections are arranged in a circular array along the center of the heating plate body, which improves the water guiding and stirring efficiency and accelerates the flow and discharge efficiency of condensate. Furthermore, the width of the water guide sections gradually decreases along the direction close to the drainage support base, which not only optimizes the flow path of condensate and makes the condensate flow more smoothly to the drainage system, but also helps to reduce water flow resistance and improve drainage efficiency.

[0012] Preferably, the upper surface of the rotating heating plate gradually slopes downward in a direction away from the center point of the rotating heating plate to form an inclined guide slope.

[0013] By adopting the above technical solution, the upper surface of the rotating heating plate gradually slopes downwards in the direction away from the center point to form an inclined guide slope; this effectively promotes the flow of condensate, allowing the condensate to flow more smoothly along the slope to the drainage system under the action of gravity, thereby improving drainage efficiency, reducing water retention on the rotating heating plate, and helping to prevent freezing and water accumulation.

[0014] Preferably, the water guide base is provided with an inclined water guide groove, the rotating heating plate is inserted into the inclined water guide groove, and the bottom of the inclined water guide groove gradually slopes downward in the direction facing the active drainage mechanism.

[0015] By adopting the above technical solution, the condensate thrown from the rotating heating plate impacts the side wall of the inclined water guide channel and flows into the active drainage mechanism through the inclined bottom of the channel. The gradually downward inclined design of the bottom of the inclined water guide channel towards the active drainage mechanism effectively guides the condensate to flow along the inclined surface towards the active drainage mechanism. This application optimizes the water flow path, reduces water flow resistance, improves drainage efficiency, and facilitates the rapid discharge of condensate, thereby reducing the risk of freezing.

[0016] Preferably, the drainage support base is provided with a fixing groove for inserting the evaporation device, and a water guide hole located at the bottom of the fixing groove and communicating with the inclined water guide groove, the water guide hole being located above the rotating heating plate.

[0017] By adopting the above technical solution, the fixed groove is used for the stable insertion of the evaporation device, and the water guide hole is connected to the inclined water guide groove at the bottom of the fixed groove and is located above the rotating heating plate; this allows the condensate to be effectively guided from the evaporation device to the fixed groove, and then discharged to the rotating heating plate through the water guide hole, which improves the drainage efficiency of the integrated air source water heater and the overall performance of the system, while reducing the risk of condensate accumulation and freezing inside the equipment.

[0018] Preferably, the active drainage mechanism includes a fixed drainage pipe disposed on the water guide base, a rotating drainage pipe inserted into the fixed drainage pipe, and a drainage pipe driving assembly disposed on the fixed drainage pipe, the drainage pipe driving assembly being used to drive the rotating drainage pipe to rotate relative to the fixed drainage pipe.

[0019] By adopting the above technical solution, a fixed drain pipe is set on the water guide base, and a rotatable drain pipe is inserted inside the fixed drain pipe. With the help of the drain pipe drive assembly on the fixed drain pipe, the dynamic rotation of the rotatable drain pipe is realized. The drain pipe drive assembly is used to drive the rotatable drain pipe to rotate relative to the fixed drain pipe, making the drainage process more proactive and efficient, effectively promoting the discharge of condensate and preventing water accumulation and freezing.

[0020] Preferably, the active drainage mechanism further includes a water-guiding funnel inserted into the fixed drainage pipe, wherein the large opening end of the water-guiding funnel is connected to the inner wall of the fixed drainage pipe, and the small opening end of the water-guiding funnel is inserted into the rotating drainage pipe.

[0021] By adopting the above technical solution, the tight connection between the large opening end of the water guiding funnel and the inner wall of the fixed drainage pipe ensures the stability and reliability of drainage. Meanwhile, the small opening end of the water guiding funnel is inserted into the rotating drainage pipe, which can effectively guide the water flow into the rotating drainage pipe and realize the smooth transfer of water flow. This not only improves drainage efficiency but also reduces water flow resistance, thereby making the entire drainage system more efficient and reliable.

[0022] Preferably, the rotating drain pipe includes a drain pipe body, a threaded protrusion spirally arranged along the inner side wall of the drain pipe body, and an electric heating part inserted into the threaded protrusion and arranged along the length direction of the threaded protrusion; the electric heating part is electrically connected to the temperature sensor.

[0023] By adopting the above technical solution, the spiral arrangement of the threaded protrusion helps to improve the dynamics and stability of the water flow within the drain pipe body. The threaded protrusion has the functions of accelerating water flow and guiding it. The electric heating part is arranged along the length of the threaded protrusion and is connected to the temperature sensor to ensure that heating can be activated in time when the ambient temperature drops, preventing ice formation inside the active drainage mechanism. This not only promotes the smooth discharge of condensate, but also effectively avoids freezing problems that may occur in low-temperature environments with the assistance of the electric heating part, achieving efficient drainage and antifreeze functions and improving the applicability and reliability of the rotary drain pipe in cold environments.

[0024] Preferably, the drain pipe drive assembly includes a rotary bearing disposed between the fixed drain pipe and the rotary drain pipe, a ring gear sleeved on the outside of the rotary drain pipe, a drive motor disposed on the fixed drain pipe, and a drive gear disposed at the output end of the drive motor and meshing with the ring gear.

[0025] By adopting the above technical solution, the rotary bearing ensures smooth rotation between the fixed drain pipe and the rotary drain pipe, reducing friction. The ring gear is sleeved on the outside of the rotary drain pipe, and the drive motor is installed on the fixed drain pipe. The drive gear is located at the output end of the drive motor and meshes with the ring gear, thereby transmitting the power of the drive motor to the rotary drain pipe and realizing the active rotation of the rotary drain pipe. This not only improves drainage efficiency but also effectively prevents icing and blockage problems inside the pipe through the active rotation mechanism.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Condensate from the evaporator drips onto the rotating heating plate via the drain support base. The rotating drive assembly drives the rotating heating plate to rotate, and the centrifugal force of the rotating heating plate throws the condensate into the water guide base. The active drainage mechanism then discharges the condensate to the outside of the water guide base, increasing the condensate discharge rate and reducing water accumulation. When the temperature on the rotating heating plate is lower than the preset temperature, the temperature sensor triggers the rotating heating plate to heat up. This allows the rotating heating plate to heat the condensate while throwing it out, preventing the condensate from freezing and clogging. The active drainage mechanism in this application further improves drainage efficiency, avoids the freezing and poor drainage problems existing in the drainage structure of traditional air source water heaters, enhances the stability and reliability of the integrated air source water heater in low-temperature environments, and improves the service life and user satisfaction of the integrated air source water heater. 2. When the rotating heating plate rotates, the condensate is guided out through the water guide section. The heating component is electrically connected to the temperature sensor. When the temperature on the rotating heating plate is lower than the preset temperature, the temperature sensor triggers the heating component to heat up. This not only ensures the effective discharge of condensate and prevents freezing in low-temperature environments, but also improves the discharge efficiency of condensate and enhances the operating efficiency and stability of the air source water heater. 3. A fixed drain pipe is installed on the water guide base, and a rotatable drain pipe is inserted inside the fixed drain pipe. In conjunction with the drain pipe drive assembly on the fixed drain pipe, the dynamic rotation of the rotatable drain pipe is realized. The drain pipe drive assembly is used to drive the rotatable drain pipe to rotate relative to the fixed drain pipe, making the drainage process more proactive and efficient, effectively promoting the discharge of condensate and preventing water accumulation and freezing.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses an air-source heat pump water heater with a drainage structure. (Refer to...) Figures 1 to 3 An air source water heater with a drainage structure includes a shell support 1, a water tank 2 disposed within the shell support 1, a condensing device 3 disposed on the water tank 2, an evaporating device 4 disposed above the water tank 2, an expansion valve 5 disposed between the condensing device 3 and the evaporating device 4, a compressor 6, and a drainage device 7 disposed between the evaporating device 4 and the water tank 2. The drainage device 7 includes a drainage support base 71, a water guide base 72 located below the drainage support base 71, a rotary drive assembly 73 located at the bottom of the water guide base 72, a rotary heating plate 74 located at the output end of the rotary drive assembly 73 and inserted into the water guide base 72, a temperature sensor 75 located on the rotary heating plate 74 and electrically connected to the rotary heating plate 74, and an active drainage mechanism 76 for connecting the interior and exterior spaces of the water guide base 72; when the temperature on the rotary heating plate 74 is lower than the preset temperature, the temperature sensor 75 triggers the rotary heating plate 74 to heat up.

[0034] The condensate on the evaporator 4 drips onto the rotating heating plate 74 via the drain support base 71. The rotating drive assembly 73 drives the rotating heating plate 74 to rotate, and the centrifugal force of the rotating heating plate 74 throws the condensate into the water guide base 72. The active drainage mechanism 76 then discharges the condensate to the outside of the water guide base 72, improving the condensate discharge rate and reducing water accumulation. When the temperature on the rotating heating plate 74 is lower than the preset temperature, the temperature sensor 75 triggers the rotating heating plate 74 to heat up. This allows the rotating heating plate 74 to heat the condensate while throwing it out, preventing the condensate from freezing and clogging. The active drainage mechanism 76 further improves drainage efficiency, avoids the freezing and poor drainage problems existing in the drainage structure of traditional air source water heaters, enhances the stability and reliability of the integrated air source water heater in low-temperature environments, and improves the service life and user satisfaction of the integrated air source water heater.

[0035] This application also discloses that a temperature sensor 75 is electrically connected to a rotary drive assembly 73. When the temperature on the rotary heating plate 74 is lower than a preset temperature, the temperature sensor 75 triggers the rotary drive assembly 73 to drive the rotary heating plate 74 to rotate, or triggers the rotary drive assembly 73 to drive the rotary heating plate 74 to accelerate its rotation, thereby improving the efficiency of condensate drainage and the efficiency of melting and discharging frozen condensate. The preset temperature in this application is preferably 0°C; the condensing device 3 is preferably a condenser, and the evaporating device 4 is preferably an evaporator. The expansion valve 5 is connected to one side of the condensing device 3 and the evaporating device 4 respectively through conduits, and the compressor 6 is connected to the other side of the condensing device 3 and the evaporating device 4 respectively through conduits.

[0036] The evaporator 4, expansion valve 5 and compressor 6 of this application are all mounted on the drain support base 71.

[0037] Furthermore, such as Figure 2 As shown, the rotating heating plate 74 includes a heating plate body 741, a water guide portion 742 disposed on the heating plate body 741, and a heating component 743 inserted in the water guide portion 742; the heating component 743 is electrically connected to a temperature sensor 75, and when the temperature on the rotating heating plate 74 is lower than the preset temperature, the temperature sensor 75 triggers the heating component 743 to heat.

[0038] When the rotating heating plate 74 rotates, the condensate is guided and thrown out through the water guide 742. It is electrically connected to the temperature sensor 75 through the heating component 743. When the temperature on the rotating heating plate 74 is lower than the preset temperature, the temperature sensor 75 triggers the heating component 743 to heat. This not only ensures the effective discharge of condensate and prevents freezing in low-temperature environments, but also improves the discharge efficiency of condensate and enhances the operating efficiency and stability of the air source water heater.

[0039] Furthermore, after the air source water heater has finished operating, the rotating heating plate 74 and the heating element 743 will continue to run for a preset period of time to quickly heat and dry the water stains in the water guide base 72, reducing the accumulation of residual condensate and the growth of bacteria. The heating element 743 in this application is preferably a heating tube or a heating wire.

[0040] Furthermore, such as Figure 2 As shown, multiple water guiding sections 742 are arranged in a circular array along the center of the heating plate body 741, and the width of the water guiding section 742 gradually decreases along the direction close to the drainage support base 71.

[0041] This application improves the efficiency of water guiding and agitation by arranging multiple water guiding sections 742 in a circular array along the center of the heating plate body 741, thereby accelerating the flow and discharge efficiency of condensate. Furthermore, the width of the water guiding sections 742 gradually decreases along the direction close to the drain support base 71, which not only optimizes the flow path of condensate, allowing it to flow more smoothly to the drainage system, but also helps to reduce water flow resistance and improve drainage efficiency, thereby further enhancing the performance and service life of the integrated air source water heater.

[0042] The water guiding part 742 of this application is preferably a curved structure, which facilitates the flow of condensate along the curvature of the water guiding part 742 and further reduces water flow resistance.

[0043] Specifically, such as Figure 2 and Figure 3 As shown, the upper surface of the rotating heating plate 74 gradually slopes downward in a direction away from the center point of the rotating heating plate 74 to form an inclined guide slope.

[0044] The upper surface of the rotating heating plate 74 of this application gradually slopes downwards in the direction away from the center point to form an inclined guide slope. This design effectively promotes the flow of condensate, allowing the condensate to flow more smoothly along the slope to the drainage system under the action of gravity, thereby improving drainage efficiency, reducing water retention on the rotating heating plate 74, helping to prevent freezing and water accumulation, and ensuring the stable operation of the integrated air source water heater under various environmental conditions.

[0045] More specifically, such as Figure 2 and Figure 3 As shown, the water guide base 72 is provided with an inclined water guide groove 721, and the rotating heating plate 74 is inserted into the inclined water guide groove 721. The bottom of the inclined water guide groove 721 gradually slopes downward in the direction facing the active drainage mechanism 76.

[0046] In this application, the condensate splashed from the rotating heating plate 74 impacts the side wall of the inclined water guide channel 721 and flows into the active drainage mechanism 76 through the inclined bottom of the inclined water guide channel 721. The gradually downward inclined design of the bottom of the inclined water guide channel 721 along the direction facing the active drainage mechanism 76 effectively guides the condensate to flow along the inclined surface towards the active drainage mechanism 76. This application optimizes the water flow path, reduces water flow resistance, improves drainage efficiency, and helps to quickly discharge condensate, thereby reducing the risk of freezing.

[0047] In addition, such as Figure 2 and Figure 3 As shown, the drainage support base 71 is provided with a fixing groove 711 for inserting the evaporation device 4, and a water guide hole 712 located at the bottom of the fixing groove 711 and communicating with the inclined water guide groove 721. The water guide hole 712 is located above the rotating heating plate 74.

[0048] The fixed groove 711 of this application is used for the stable insertion of the evaporation device 4. The water guide hole 712 is connected to the inclined water guide groove 721 at the bottom of the fixed groove 711 and is located above the rotating heating plate 74. This allows the condensate to be effectively guided from the evaporation device 4 to the fixed groove 711 and then discharged to the rotating heating plate 74 through the water guide hole 712. This improves the drainage efficiency of the integrated air source water heater and the overall performance of the system, while reducing the risk of condensate accumulation and freezing inside the equipment.

[0049] And, as Figure 3 and Figure 4 As shown, the active drainage mechanism 76 includes a fixed drainage pipe 761 disposed on the water guide base 72, a rotating drainage pipe 762 inserted into the fixed drainage pipe 761, and a drainage pipe drive assembly 763 disposed on the fixed drainage pipe 761. The drainage pipe drive assembly 763 is used to drive the rotating drainage pipe 762 to rotate relative to the fixed drainage pipe 761.

[0050] This application achieves dynamic rotation of the rotating drain pipe 762 by setting a fixed drain pipe 761 on the water guide base 72 and inserting a rotatable rotating drain pipe 762 inside the fixed drain pipe 761, in conjunction with the drain pipe drive assembly 763 on the fixed drain pipe 761. The drain pipe drive assembly 763 is used to drive the rotating drain pipe 762 to rotate relative to the fixed drain pipe 761, making the drainage process more proactive and efficient, effectively promoting the discharge of condensate, and preventing water accumulation and freezing.

[0051] Furthermore, such as Figure 4 As shown, the active drainage mechanism 76 also includes a water-guiding funnel 764 installed in the fixed drainage pipe 761. The large opening end of the water-guiding funnel 764 is connected to the inner wall of the fixed drainage pipe 761, and the small opening end of the water-guiding funnel 764 is installed in the rotating drainage pipe 762.

[0052] The tight connection between the large opening end of the water-guiding funnel 764 and the inner wall of the fixed drain pipe 761 ensures the stability and reliability of drainage. Meanwhile, the small opening end of the water-guiding funnel 764 is inserted into the rotating drain pipe 762, which can effectively guide the water flow into the rotating drain pipe 762, realizing the smooth transfer of water flow. This not only improves drainage efficiency but also reduces water flow resistance, thereby making the entire drainage system more efficient and reliable.

[0053] Furthermore, such as Figure 4 As shown, the rotating drain pipe 762 includes a drain pipe body 7621, a threaded protrusion 7622 spirally arranged along the inner sidewall of the drain pipe body 7621, and an electric heating part 7623 inserted into the threaded protrusion 7622 and arranged along the length direction of the threaded protrusion 7622; the electric heating part 7623 is electrically connected to the temperature sensor 75.

[0054] The spiral arrangement of the threaded protrusion 7622 in this application helps to improve the dynamics and stability of the water flow inside the drain pipe body 7621. The threaded protrusion 7622 has the function of accelerating water flow and guiding it. The electric heating part 7623 is arranged along the length of the threaded protrusion 7622 and is connected to the temperature sensor 75 to ensure that heating can be activated in time when the ambient temperature drops, preventing ice formation inside the active drainage mechanism 76. This not only promotes the smooth discharge of condensate, but also effectively avoids freezing problems that may occur in low-temperature environments with the assistance of the electric heating part 7623, achieving efficient drainage and antifreeze functions, and improving the applicability and reliability of the rotary drain pipe 762 in cold environments.

[0055] The electric heating element 7623 in this application is preferably an electric heating wire.

[0056] Specifically, such as Figure 4 As shown, the drain pipe drive assembly 763 includes a rotary bearing 7631 disposed between the fixed drain pipe 761 and the rotary drain pipe 762, a ring gear 7632 sleeved on the outside of the rotary drain pipe 762, a drive motor 7633 disposed on the fixed drain pipe 761, and a drive gear 7634 disposed at the output end of the drive motor 7633 and meshing with the ring gear 7632.

[0057] The rotary bearing 7631 of this application ensures smooth rotation between the fixed drain pipe 761 and the rotary drain pipe 762, reducing friction. The ring gear 7632 is sleeved on the outside of the rotary drain pipe 762. The drive motor 7633 is mounted on the fixed drain pipe 761, while the drive gear 7634 is located at the output end of the drive motor 7633. The drive gear 7634 meshes with the ring gear 7632, thereby transmitting the power of the drive motor 7633 to the rotary drain pipe 762, realizing the active rotation of the rotary drain pipe 762. This not only improves drainage efficiency but also effectively prevents icing and blockage problems inside the pipe through the active rotation mechanism.

[0058] The implementation principle of an air source water heater with a drainage structure according to an embodiment of this application is as follows: The condensate on the evaporator 4 drips onto the rotating heating plate 74 via the drain support base 71. The rotation drive assembly 73 drives the rotating heating plate 74 to rotate, and the centrifugal force of the rotating heating plate 74 throws the condensate into the water guide base 72. The active drainage mechanism 76 then discharges the condensate to the outside of the water guide base 72, improving the condensate discharge rate and reducing water accumulation. When the temperature on the rotating heating plate 74 is lower than the preset temperature, the temperature sensor 75 triggers the rotating heating plate 74 to heat up. This allows the rotating heating plate 74 to heat the condensate while throwing it out, preventing the condensate from freezing and clogging. The active drainage mechanism 76 further improves drainage efficiency, avoids the freezing and poor drainage problems existing in the drainage structure of traditional air source water heaters, enhances the stability and reliability of the integrated air source water heater in low-temperature environments, and improves the service life and user satisfaction of the integrated air source water heater. This application guides and ejects condensate through the water guide section 742, and connects it to the temperature sensor 75 via the heating component 743. When the temperature on the rotating heating plate 74 is lower than the preset temperature, the temperature sensor 75 triggers the heating component 743 to heat the water. This not only ensures the effective discharge of condensate and prevents freezing in low-temperature environments, but also improves the discharge efficiency of condensate and enhances the operating efficiency and stability of the air source water heater. This application achieves dynamic rotation of the rotating drain pipe 762 by setting a fixed drain pipe 761 on the water guide base 72 and inserting a rotatable rotating drain pipe 762 inside the fixed drain pipe 761, in conjunction with the drain pipe drive assembly 763 on the fixed drain pipe 761. The drain pipe drive assembly 763 is used to drive the rotating drain pipe 762 to rotate relative to the fixed drain pipe 761, making the drainage process more proactive and efficient, effectively promoting the discharge of condensate, and preventing water accumulation and freezing.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
