Description

TECHNICAL FIELD

[0001] The present application relates to the field of cooking equipment, and particularly relates to a damping door control structure and a cooking equipment. BACKGROUND

[0002] In the field of cooking equipment, the opening and closing experience and damping effect of a door body are important aspects that users pay attention to. In the prior art, traditional door body damping structures, such as mechanical or hydraulic dampers installed on hinges, usually face problems such as high cost, complex structure, and high strength requirements for the dampers themselves. In addition, some liquid dampers or air chamber dampers need a certain recovery time to provide damping effect again after completing a damping stroke, which causes the damping function to be unable to respond in time when the door is opened and closed continuously in a short time, affecting the user experience and smooth operation of the equipment. SUMMARY

[0003] Therefore, it is necessary to provide a damping door control structure and a cooking equipment to solve the above problems, which can realize low-cost opening and closing damping without recovery time limitation, thereby improving user experience and product reliability.

[0004] The present application provides a damping door control structure for a cooking equipment, the cooking equipment comprising a cabinet, comprising:

[0005] a door body assembly rotatably arranged on the cabinet to open / close the cabinet, and a damping assembly comprising a magnet and a copper pipe, the magnet being protrudingly arranged on one end of the door body assembly close to the cabinet, and the copper pipe being arranged on one end of the cabinet close to the door body assembly, the magnet extending into the copper pipe during the closing process of the door body assembly, and the magnet being separated from the copper pipe during the opening process of the door body assembly.

[0006] In this way, when the door body assembly is closed, the magnet extends into the copper pipe, and the magnetic field of the magnet passes through the wall of the copper pipe, causing the magnetic flux in the copper pipe to change. According to Faraday's law of electromagnetic induction, eddy current will be generated in the copper pipe. According to Lenz's law, the magnetic field direction of the eddy current always hinders the relative movement of the magnet and the copper pipe, thereby forming resistance and achieving damping effect. At the same time, the damping force of this structure is proportional to the speed of the relative movement of the magnet and the copper pipe, so that the closing process is smooth and soft. Since the eddy current damping is a non-contact type without mechanical wear, and does not require liquid or gas as a medium, the structure is simple, the manufacturing cost is low, and there is no recovery time required by traditional liquid or air dampers, so that continuous and rapid opening and closing operation can be realized, and stable damping effect can be provided at all times.

[0007] In one of the embodiments, the door body assembly is provided with a magnet hole corresponding to the magnet, and the magnet is slidably arranged in the magnet hole to extend / retract the door body assembly. In the extended state, the magnet hole can be inserted into / detached from the copper pipe.

[0008] In this way, by slidably arranging the magnet in the magnet hole inside the door body assembly, the hidden design of the magnet is realized.

[0009] In one of the embodiments, the damping door control structure further comprises a reset assembly arranged in the door body assembly and capable of driving the magnet to slide in the magnet hole.

[0010] In this way, the reset assembly ensures that the magnet can be reliably retracted inside the door body assembly after the door body assembly is opened, maintaining the neat appearance and easy cleanability of the door body assembly. Meanwhile, the reset assembly drives the magnet to slide and extend into the magnet hole, ensuring that the magnet can extend into the copper pipe to achieve the damping effect.

[0011] In one of the embodiments, the bottom of the door body assembly is rotationally connected to the bottom of the cabinet, and the reset assembly comprises a support member slidably arranged in the door body assembly, the support member having a pushing state and an avoiding state.

[0012] In the pushing state, the support member pushes the magnet to make the magnet extend out of the door body assembly; in the avoiding state, the support member is separated from the magnet to make the magnet retract into the door body assembly under the action of gravity.

[0013] In this way, the support member realizes accurate control of the extension and retraction of the magnet. When the door body assembly is closed, the support member pushes the magnet out, ensuring that the damping effect is timely intervened. When the door body assembly is opened, the support member is converted to the avoiding state, so that the magnet stably retracts into the door body assembly under the action of its own gravity. This design utilizes gravity, simplifies the reset mechanism, and reduces energy consumption and mechanical complexity.

[0014] In one of the embodiments, the damping door control structure further comprises a hinge assembly, the hinge assembly comprising a fixed part and a rotating part rotationally arranged on the fixed part, the fixed part being arranged on the cabinet, and the rotating part being arranged on the door body assembly.

[0015] The reset assembly further comprises a traction rope and a compression spring, two ends of the traction rope being respectively connected to the fixed part and the support member, and two ends of the compression spring being respectively connected to the rotating part and the support member.

[0016] The rotating part presses the traction rope to pull the support to the pushing state during the closing of the door body assembly, and the compression spring is compressed and applies a force to the support to move it to the avoiding state.

[0017] In this way, when the door body assembly is closed, the rotating part presses the traction rope to pull the support to the pushing state, so that the magnet extends and ensures that the damping effect is timely intervened. When the door body assembly is opened, the traction rope is relaxed, and the elastic force of the compression spring pushes the support to the avoiding state away from the hinge assembly, so that the magnet is retracted under the action of gravity. This mechanical linkage design uses the movement of the door body assembly to drive the extension and retraction of the magnet without additional power.

[0018] In one embodiment, the damping door control structure further comprises a damping column arranged in the box body, the damping column comprising a sealing end extending into the copper pipe away from the magnet, and the outer wall of the sealing end being in close contact with the inner wall of the copper pipe.

[0019] In this way, the sealing end of the damping column extends into the copper pipe and is in close contact with the inner wall. When the door body assembly is closed, the magnet moves into the copper pipe, and an air cavity is formed between the magnet and the damping column. The entry of the magnet compresses the air in the air cavity, generating additional air damping effect.

[0020] In one embodiment, the damping door control structure further comprises a micro switch assembly arranged in the box body, the damping column being capable of sliding along the length direction of the copper pipe, the sealing end being a ferrous part, and the magnet being capable of attracting the sealing end when the door body assembly is closed to make the damping column slide to a position triggering the micro switch assembly.

[0021] In this way, in combination with the air damping provided by the damping column and the eddy current damping provided by the magnet and the copper pipe, this magnetic attraction type triggering mechanism not only realizes the closing signal of the door body assembly, but also further enhances the sealing of the door body assembly, reduces the wear of the door body assembly and the switch, and prolongs the service life of the product.

[0022] In one embodiment, the micro switch assembly comprises a micro switch and a pressing part capable of rotating relative to the micro switch, and the damping column further comprises a protruding part towards the pressing part, the protruding part pushing the pressing part to rotate to a position contacting and triggering the micro switch when the door body assembly is closed.

[0023] In this way, the protrusion on the damping column precisely pushes the pressing member to rotate, thereby triggering the micro switch. Compared with direct pressing triggering, the rotary pressing member design can provide a longer action stroke and a softer triggering force, reducing mechanical wear of the micro switch and prolonging its service life.

[0024] In one embodiment, the magnet is arranged at an end of the door body assembly away from the hinge.

[0025] In this way, placing the magnet at the free end of the door body assembly away from the hinge can maximize the linear velocity of the relative motion between the magnet and the copper pipe, thereby generating a stronger eddy current damping effect under the same magnetic field strength; placing the magnet at the side edge of the door body assembly allows the damping assembly to be compactly integrated on the side of the cooking device, effectively utilizing the space that is usually not fully utilized.

[0026] The application also provides a cooking device comprising a cabinet and the damping door control structure described above.

[0027] In this way, the cooking device integrated with the damping door control structure described above can obtain a continuous, adjustable, and non-recovery waiting damping effect during door opening, the door control triggering does not generate a reverse force, and the door seal is more reliable; the overall structure is simple, the cost is low, and the maintenance is convenient.

[0034] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0039] In the field of cooking equipment, the opening and closing experience and damping effect of the door are important aspects that users care about. In existing technologies, traditional door damping structures, such as mechanical or hydraulic dampers mounted on hinges, typically face problems such as high cost, complex structure, and high strength requirements for the damper itself. Furthermore, some liquid dampers or air chamber dampers require a certain recovery time after completing one damping stroke before they can provide damping again. This can lead to the damping function failing to respond promptly when the door is opened and closed repeatedly in a short period, affecting the user experience and the smooth operation of the equipment.

[0040] Therefore, in order to solve the above problems, such as Figures 1 to 4 As shown, this application provides a damping door control structure and cooking device that can achieve low-cost door opening and closing damping without recovery time limitations, thereby improving user experience and product reliability.

[0041] like Figures 1 to 3 As shown, this application provides a damping gate structure for a cooking device. The cooking device includes a housing 200, and the damping gate structure includes a door assembly 3 and a damping assembly 1. The door assembly 3 is rotatably mounted on the housing 200 to open or close the housing 200. The damping assembly 1 includes a magnet 11 and a copper tube 12. The magnet 11 protrudes from one end of the door assembly 3 near the housing 200, and the copper tube 12 is mounted on one end of the housing 200 near the door assembly 3. During the closing process of the door assembly 3, the magnet 11 extends into the copper tube 12. During the opening process of the door assembly 3, the magnet 11 disengages from the copper tube 12.

[0042] With this configuration, when the door assembly 3 is closed, the magnet 11 extends into the copper tube 12. The magnetic field of the magnet 11 passes through the wall of the copper tube 12, causing a change in the magnetic flux within the copper tube 12. According to Faraday's law of electromagnetic induction, eddy currents are generated in the copper tube 12. According to Lenz's law, the direction of the magnetic field of the eddy currents always opposes the relative motion between the magnet 11 and the copper tube 12, thus forming resistance and achieving a damping effect. Simultaneously, the damping force of this structure is directly proportional to the speed of the magnet 11 relative to the copper tube 12; that is, the faster the door closes, the greater the damping, effectively avoiding the impact and noise caused by the violent closing of the door, making the closing process smooth and gentle, greatly improving the user experience. Since eddy current damping is non-contact, there is no mechanical wear, and it does not require liquid or gas as a medium, therefore the structure is simple, the manufacturing cost is low, and there is no recovery time required by traditional liquid or air dampers. It can achieve continuous and rapid door opening and closing operations, always providing a stable damping effect, effectively solving the shortcomings of existing dampers that have long recovery times and cannot immediately proceed to the next action.

[0043] like Figures 1 to 3 As shown, in one embodiment, the door assembly 3 has a magnet hole 321 corresponding to the magnet 11. The magnet 11 is slidably disposed in the magnet hole 321 to extend or retract from the door assembly 3. In the extended state, the magnet hole 321 can extend into or detach from the copper tube 12. In the illustrated embodiment, the door assembly 3 includes an outer plate 31 and an inner plate 32 stacked on the side of the outer plate 31 near the housing 200. The inner plate 32 has a door space 33 formed between the outer plate 31 and the inner plate 32, corresponding to the magnet hole 321, with the magnet 11 located therebetween. This arrangement achieves a concealed design for the magnet 11 by slidably disposing of the magnet 11 within the magnet hole 321 inside the door assembly 3. When the door assembly 3 is opened, the magnet 11 retracts into the door assembly 3 and does not protrude from the surface of the door assembly 3, thus maintaining the overall aesthetics of the door assembly 3, avoiding obstruction during cleaning, facilitating cleaning of the cooking equipment, and improving the user experience. At the same time, this internal sliding design also protects the magnet 11 from damage or contamination from the external environment, extends its service life, and ensures that the magnet 11 can extend precisely and cooperate with the copper tube 12 when needed to achieve a reliable damping effect.

[0044] like Figures 1 to 3As shown, in one embodiment, the damping gate structure further includes a reset component 4, which is disposed within the door assembly 3 and can drive the magnet 11 to slide within the magnet hole 321. In the illustrated embodiment, the reset component 4 is located in the door space 33 formed between the outer plate 31 and the inner plate 32. This arrangement ensures that the magnet 11 can reliably retract into the door assembly 3 after the door assembly 3 is opened, maintaining the clean appearance and ease of cleaning of the door assembly 3, and avoiding potential damage or interference with user cleaning operations caused by the magnet 11 protruding for extended periods. Simultaneously, the reset component 4 drives the magnet 11 to slide out of the magnet hole 321, ensuring that the magnet 11 can extend into the copper tube 12 to achieve a damping effect.

[0045] like Figures 1 to 3 As shown, the bottom of the door assembly 3 is rotatably connected to the bottom of the housing 200. The reset assembly 4 includes a support member 41 slidably disposed within the door assembly 3. The support member 41 has a pushing state and a yielding state. In the pushing state, the support member 41 pushes against the magnet 11 so that the magnet 11 extends out of the door assembly 3. In the yielding state, the support member 41 separates from the magnet 11 so that the magnet 11 retracts into the door assembly 3 under the action of gravity. In the illustrated embodiment, the support member 41 includes a pushing part 411, a clearance part 412, and a guide part 413. The two ends of the guide part 413 are connected to the pushing part 411 and the clearance part 412, respectively. The guide part 413 gradually tilts towards the side closer to the magnet 11 from the clearance part 412 to the pushing part 411. In the pushing state, the pushing part 411 pushes against the magnet 11, causing the magnet 11 to extend out of the magnet hole 321. In the clearance state, the pushing part 411 separates from the magnet 11, and the clearance part 412 guides the magnet 11 to retract into the magnet hole 321 under gravity. During the opening process of the door assembly 3, the guide part 413 guides and drives the magnet 11 to gradually extend out of the magnet hole 321. With this configuration, the support member 41, through the ingenious design of its pushing part 411, clearance part 412, and guide part 413, achieves precise control over the extension and retraction of the magnet 11. When the door assembly 3 is closed, the support member 41 pushes out the magnet 11, ensuring the timely intervention of the damping effect. When the door assembly 3 is opened, the support member 41 switches to a yielding state, allowing the magnet 11 to smoothly retract into the door assembly 3 under its own gravity. This design utilizes gravity, simplifies the reset mechanism, reduces energy consumption and mechanical complexity, and the guiding effect of the yielding part 412 ensures that the magnet 11 returns to its position smoothly and without obstruction. This, combined with the structure in which the magnet 11 is slidably set in the magnet hole 321, improves the reliability and lifespan of the mechanism and maintains the neat appearance of the door assembly 3.

[0046] In another embodiment, the top of the door assembly 3 is rotatably connected to the top of the housing 200 or the side of the door assembly 3 is rotatably connected to the side of the housing 200.

[0047] In another embodiment, the support member 41 may be designed to be mounted in the door assembly 3 in a rotating or other manner.

[0048] In another embodiment, the support 41 may be designed as a camshaft, slider, rocker arm, or rack and pinion mechanism or other structure capable of pushing out the magnet 11 or retracting the magnet 11.

[0049] like Figures 2 to 4 As shown in the illustrated embodiment, the damping door control structure further includes a hinge assembly 2. The hinge assembly 2 includes a fixed part 21 and a rotating part 22 rotatably disposed on the fixed part 21. The fixed part 21 is used to mount on the housing 200, and the rotating part 22 is disposed on the door assembly 3. The reset assembly 4 further includes a traction rope 42 and a compression spring 43. The two ends of the traction rope 42 are respectively connected to the fixed part 21 and the support member 41, and the two ends of the compression spring 43 are respectively connected to the rotating part 22 and the support member 41. During the closing process of the door assembly 3, the rotating part 22 presses the traction rope 42 to pull the support member 41 to the pushing state, and the compression spring 43 is compressed and applies a force to the support member 41 to move it toward the avoidance state. In the illustrated embodiment, the rotating part 22 includes a support member 221 at the end rotatably connected to the rotating part 22 away from the fixed part 21, and the compression spring 43 is fixedly disposed on the upper surface of the support member 221. The rotating part 22 includes an abutting part 222 that abuts against the end of the traction rope 42 near the fixed part 21. During the closing process of the door assembly 3, the abutting part 222 presses against the traction rope 42. This configuration utilizes the rotational motion of the hinge itself to drive the support member 41 via the traction rope 42. Specifically, when the door assembly 3 is closed, the abutting part 222 of the rotating part 22 presses against the traction rope 42, pulling the support member 41 towards the side closer to the hinge assembly 2 to a pushing state, causing the magnet 11 to extend, ensuring timely intervention of the damping effect. When the door assembly 3 is opened, the traction rope 42 relaxes, and the elastic force of the compression spring 43 pushes the support member 41 towards the side away from the hinge assembly 2 back to an avoidance state, causing the magnet 11 to retract under gravity. This mechanical linkage design utilizes the movement of the door assembly 3 itself to drive the extension and retraction of the magnet 11, requiring no additional power. The structure is reliable and responsive, ensuring that the damping function takes effect promptly when needed and is completely concealed when not needed. The combination of the sliding design of the magnet 11 and the pushing or avoiding function of the support 41 ensures the smooth closing of the door assembly 3 and the reliable reset of the magnet 11.

[0050] In another embodiment, the magnet 11 can be driven to extend or retract into the magnet hole 321 by other means such as electric push rods or magnetic attraction.

[0051] In another embodiment, the rotating part 22 of the hinge assembly 2 can be integrated with a cam structure, which directly pushes or pulls the support 41 when the door assembly 3 rotates to provide more precise motion control.

[0052] like Figures 1 to 3 As shown, in one embodiment, the damping gate structure further includes a damping column 52 for mounting on the housing 200. The damping column 52 includes a sealing end 521 that extends into the end of the copper tube 12 away from the magnet 11, and the outer wall of the sealing end 521 is in contact with the inner wall of the copper tube 12. In the illustrated embodiment, the damping gate structure also includes a fixing plate 51 mounted on the housing 200, with both the copper tube 12 and the damping column 52 mounted on the fixing plate 51. Of course, the copper tube 12 and the damping column 52 can also be directly mounted on the housing 200. With this configuration, the sealing end 521 of the damping column 52 extends into the copper tube 12 and is tightly fitted to the inner wall. When the door assembly 3 is closed, the magnet 11 moves into the copper tube 12, forming a relatively sealed air cavity between the magnet 11 and the damping column 52. The entry of the magnet 11 compresses the air in the air cavity, producing an additional air damping effect. This air damping, combined with the eddy current damping provided by damping component 1, can significantly enhance the overall damping effect, forming an "electromagnetic + pneumatic" dual damping system. The damping force increases with speed in a quadratic curve, making the door closing feel smoother. At the same time, the sealing end 521 suppresses the entry of oil fumes, ensuring the long-term stable operation of magnet 11.

[0053] like Figures 1 to 3 As shown, in one embodiment, the damping gate control structure further includes a microswitch assembly 5 disposed on the housing 200. The damping column 52 can slide along the length of the copper tube 12, and the sealing end 521 is made of iron. When the door assembly 3 is closed, the magnet 11 can attract the sealing end 521, causing the damping column 52 to slide to the position that triggers the microswitch assembly 5. The iron component is a substance containing iron that can be attracted by the magnet 11. With this configuration, when the door assembly 3 approaches the closed position, a magnetic attraction force is generated between the magnet 11 and the iron sealing end 521 of the damping column 52. This attraction force pulls the damping column 52 to slide along the copper tube 12 until the microswitch assembly 5 is triggered. After the microswitch assembly 5 is triggered, it sends a signal such as the door closing status to the cooking device. First, the magnetic attraction provides an additional pulling force to the door assembly 3 in the same direction as the door closing. This not only does not counteract the closing force of the hinge, but also enhances its effect, allowing the door assembly 3 to seal more tightly and reliably, effectively preventing the leakage of heat or steam during cooking, thereby improving cooking efficiency and energy saving. Second, the magnetic attraction trigger avoids the reaction force that may be generated by traditional mechanical push-button switches, ensuring the smoothness of the door assembly 3 during the closing process. Combined with the air damping provided by the damping column 52 and the eddy current damping provided by the magnet 11 and the copper tube 12, this magnetic attraction trigger mechanism not only realizes the closing signal of the door assembly 3, but also further enhances the sealing performance of the door assembly 3, reduces wear on the door assembly 3 and the switch, and extends the product life.

[0054] like Figures 1 to 3As shown, in one embodiment, the microswitch assembly 5 includes a microswitch 54 and a clamping member 53 rotatable relative to the microswitch 54. The damping post 52 also includes a protrusion 522 facing the clamping member 53. When the door assembly 3 is closed, the protrusion 522 pushes the clamping member 53 to rotate to a position that contacts and triggers the microswitch 54. In the illustrated embodiment, the clamping member 53 is rotatably mounted on the fixed plate 51. This configuration allows the protrusion 522 on the damping post 52 to precisely push the clamping member 53 to rotate, thereby triggering the microswitch 54. This rotary clamping member 53 design, compared to direct press triggering, provides a longer stroke and a gentler triggering force, reducing mechanical wear on the microswitch 54 and extending its service life. Simultaneously, the rotational motion makes the triggering process smoother and more reliable, ensuring the accuracy of the door assembly 3 status signal, avoiding false triggering or missed triggering, and further improving the operational stability of the cooking equipment and the user experience. By combining the positive closing force generated by the magnet 11 adsorbing the iron sealing end 521, this precise and gentle triggering mechanism enables the door assembly 3 to close tightly and reliably send a closing signal, effectively improving the sealing performance and control precision of the cooking equipment.

[0055] Specifically, the damping column 52 also includes a return spring 523 disposed at the end of the damping column 52 away from the sealing end 521. During the opening of the door assembly 3, the return spring 523 pulls the sealing end 521 to move away from the magnet 11. The clamping member 53 includes a clamping part 531. When the door assembly 3 is closed, the protrusion 522 pushes the clamping member 53 to rotate to the position where the clamping part 531 contacts and triggers the micro switch 54. The clamping member 53 is also provided with an avoidance groove 532, which corresponds to the protrusion 522 after the door assembly 3 is opened.

[0056] In another embodiment, the clamping member 53 can be designed as a lever structure. This configuration amplifies the effect of the lever structure, allowing a smaller force to push the microswitch 54, thereby reducing the pressure on the protrusion 522 of the damping post 52, extending component life, and reducing wear on the entire triggering mechanism.

[0057] In another embodiment, the clamping member 53 can be designed as a gear tooth, magnetic attraction, or other structure that can trigger the micro switch 54.

[0058] like Figures 1 to 3As shown, in one embodiment, the magnet 11 is positioned at the end of the door assembly 3 furthest from the rotatable connection between the door assembly 3 and the housing 200. This arrangement, placing the magnet 11 at the free end of the door assembly 3 furthest from the hinge assembly 2, maximizes the linear velocity of the relative motion between the magnet 11 and the copper tube 12, thereby generating a stronger eddy current damping effect under the same magnetic field strength, resulting in greater stability of the door assembly 3 during closing. Simultaneously, this position also provides the magnet 11 with a larger lever arm, allowing the magnetic attraction force of the magnet 11 to the iron sealing end 521 to more effectively tighten the door assembly 3 during the final stage of closing, improving sealing reliability.

[0059] In another embodiment, the magnet 11 can be positioned at the center of the door assembly 3 to achieve a uniform distribution of damping force.

[0060] In another embodiment, multiple magnets 11 can be provided, each located at a different position on the door assembly 3.

[0061] In another embodiment, the mounting position of the magnet 11 can be designed as an adjustable structure.

[0062] like Figures 1 to 3 As shown, in one embodiment, the magnet 11 is disposed on the side edge of the door assembly 3. This arrangement, placing the magnet 11 on the side edge of the door assembly 3, allows the damping assembly 1 to be compactly integrated into the side of the cooking appliance, effectively utilizing space that is typically underutilized. This layout helps optimize the internal structural design of the cooking appliance, freeing up more space for other functional components, while maintaining a clean and aesthetically pleasing front panel of the door assembly 3, facilitating user operation and cleaning.

[0063] In another embodiment, a plurality of magnets 11 may be provided along the length of the side edge of the door assembly 3.

[0064] Furthermore, the damping gate structure can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the damping gate structure to perform corresponding operations, thereby realizing intelligent control of the damping gate structure and improving the user experience.

[0065] like Figures 1 to 3 As shown, this application also provides a cooking device including the aforementioned damping gate control structure. With this configuration, the cooking device, after integrating the damping gate control structure, achieves a continuous, adjustable, and unrecoverable damping effect during door opening and closing. Door control triggering does not generate a reverse force, resulting in a more reliable door seal. The overall structure is simple, low-cost, and easy to maintain.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
