Abstract

According to the elastic structure and the charging gun provided by the invention, after the buckling part is bent due to collision, the buckling part is usually difficult to be normally inserted into or pulled out of a charging port of an electric vehicle. The elastic piece is compressed through the force applied by the pressing part, so that the pressing part is allowed to further rotate, and the rotating angle and space corresponding to the buckling part are increased. Even if the buckling part is bent, the buckling part can be more easily inserted into the charging port of the electric vehicle or pulled out of the charging port. And after the buckle part is allowed to undergo physical impact and slight deformation, the buckle part continues to keep the functionality by increasing the rotation angle and space, so that the durability of the whole charging gun is improved.

Description

Technical Field

[0001] The present application relates to the field of charging guns, and in particular to an elastic structure and a charging gun. Background Art

[0002] A charging gun is a device that connects an electric vehicle to a charging pile to charge the electric vehicle.

[0003] When using a charging gun, the user needs to insert the charging gun plug into the charging port of the electric vehicle and ensure that the charging pile is activated. During the charging process, the charging gun and the electric vehicle will communicate to ensure that the charging process is safe and efficient. After charging is completed, the user needs to disconnect in the correct order to avoid damage to the charging gun or the vehicle.

[0004] The existing charging guns are designed with hooks during the design process to keep the charging gun and the electric vehicle in a stable connection and prevent the charging gun from being detached from the electric vehicle during the charging process. During the use of the charging gun, the charging gun is very easy to fall to the ground, and the fallen charging gun will directly collide with the ground. When the falling charging gun collides with the ground vertically downward, the hook directly contacts the ground, which will cause the hook to bend. The bent hook is difficult to insert into the electric vehicle during the subsequent charging process; secondly, if it is inserted into the electric vehicle, it will be difficult to pull out from the charging port of the electric vehicle after charging is completed due to the bending of the hook. Utility Model Content

[0005] In view of this, it is necessary to provide an elastic structure and a charging gun to solve the above problems.

[0006] An embodiment of the present application provides an elastic structure, comprising:

[0007] The shell is provided with a receiving cavity and a pressing port connected to the receiving cavity;

[0008] A hook, comprising a pressing portion and a buckle portion provided on the pressing portion, wherein the pressing portion is provided in the accommodating cavity and extends out of the pressing opening, and the buckle portion extends out of the accommodating cavity and can be engaged with the charging vehicle;

[0009] The elastic member is arranged in the accommodating cavity, and two ends of the elastic member are respectively supported on the accommodating cavity and the pressing portion.

[0010] In at least one embodiment of the present application, the pressing portion includes a pressing surface and a mounting surface away from the pressing surface, and the mounting surface is accommodated in the accommodating cavity;

[0011] A supporting groove is formed on the mounting surface, and one end of the elastic member is received in the supporting groove and supported in the supporting groove.

[0012] In at least one embodiment of the present application, one end of the pressing portion away from the buckle portion abuts against the elastic member.

[0013] In at least one embodiment of the present application, the pressing portion is formed to protrude toward an end away from the shell.

[0014] In at least one embodiment of the present application, the buckle portion is protruded toward a side away from the pressing portion, and the buckle portion is bent inward toward a side close to the shell.

[0015] In at least one embodiment of the present application, in the pressing direction, the projection area of ​​the pressing portion blocks the projection area of ​​the elastic member.

[0016] In at least one embodiment of the present application, the hook further includes:

[0017] The connecting rod part is arranged in the accommodating cavity, the pressing part and the buckle part are respectively arranged at two ends of the connecting rod part, and the connecting rod part is rotatably connected to the shell.

[0018] In at least one embodiment of the present application, a contact switch is disposed between the pressing portion and the elastic member.

[0019] In at least one embodiment of the present application, a rotation hole is formed in the shell, and a rotation shaft is protruding from the connecting rod portion, and the rotation shaft is movably received in the rotation hole.

[0020] An embodiment of the present application provides a charging gun, comprising any of the elastic structures described above.

[0021] The elastic structure and charging gun provided above, after the buckle part is bent due to a collision, usually this makes it difficult to normally insert or remove the buckle part from the charging port of the electric vehicle.

Even a bent buckle part can be more easily inserted into or removed from the charging port of the electric vehicle. The buckle part is allowed to continue to maintain its functionality by increasing the rotation angle and space after experiencing physical impact and slight deformation, thereby improving the durability of the entire charging gun.

[0036] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0037] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0038] An embodiment of the present application provides an elastic structure, comprising:

[0039] The shell is provided with a receiving cavity and a pressing port connected to the receiving cavity;

[0040] A hook, comprising a pressing portion and a buckle portion provided on the pressing portion, wherein the pressing portion is provided in the accommodating cavity and extends out of the pressing opening, and the buckle portion extends out of the accommodating cavity and can be engaged with the charging vehicle;

[0041] The elastic member is arranged in the accommodating cavity, and two ends of the elastic member are respectively supported on the accommodating cavity and the pressing portion.

[0042] In this embodiment, after the buckle portion is bent due to a collision, it is usually difficult to normally insert or remove the buckle portion from the charging port of the electric vehicle. The force applied by the pressing portion compresses the elastic member, thereby allowing the pressing portion to rotate further, increasing the rotation angle and space corresponding to the buckle portion. Even a bent buckle portion can be more easily inserted into or removed from the charging port of the electric vehicle.

[0043] The charging gun is allowed to continue to be used after the buckle part is slightly deformed due to inevitable falls and collisions, thereby enhancing the durability and adaptability of the product.

[0044] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0045] The embodiment of the present application provides an elastic structure 100, comprising:

[0046] The housing 110 is provided with a receiving cavity 110a and a pressing opening 110b connected to the receiving cavity 110a;

[0047] The hook 120 includes a pressing portion 121 and a buckle portion 122 disposed on the pressing portion 121, wherein the pressing portion 121 is disposed in the accommodating cavity 110a and extends out of the pressing opening 110b, and the buckle portion 122 extends out of the accommodating cavity 110a and can be engaged with the charging vehicle;

[0048] The elastic member 130 is disposed in the accommodating cavity 110 a , and two ends of the elastic member 130 are respectively supported on the accommodating cavity 110 a and the pressing portion 121 .

[0049] Please refer to Figures 1 to 7 In this embodiment, after the buckle portion 122 is bent due to a collision, it is usually difficult to normally insert or remove the buckle portion 122 from the charging port of the electric vehicle. The force applied by the pressing portion 121 compresses the elastic member 130, thereby allowing the pressing portion 121 to rotate further, increasing the rotation angle and space corresponding to the buckle portion 122. Even a bent buckle portion 122 can be more easily inserted into or removed from the charging port of the electric vehicle.

[0050] The charging gun 140 is allowed to continue to be used after the buckle portion 122 is slightly deformed due to inevitable falling and collision, thereby enhancing the durability and adaptability of the product.

[0051] Because the buckle portion 122 can still be used even after being slightly bent, the need for repair or replacement due to damage is reduced.

[0052] An elastic mechanism is provided to allow the buckle portion 122 to continue to maintain its functionality by increasing the rotation angle and space after experiencing physical impact and slight deformation, thereby improving the durability of the entire charging gun 140 .

[0053] It should be noted that the housing 110 is an external frame constituting the charging gun 140 , and an accommodating cavity 110 a and a pressing port 110 b communicating with the accommodating cavity 110 a are provided inside the housing 110 .

[0054] The accommodating cavity 110a is a space for installing the hook 120, and the pressing opening 110b is a through hole, which is a rectangular through hole in this embodiment, used to provide a movable space for the pressing portion 121 so that the pressing portion 121 can be pressed at the pressing opening 110b when subjected to external force.

[0055] The buckle portion 122 is in the shape of an arc hook, and the pressing portion 121 is in the shape of a rectangular button.

[0056] The elastic member 130 is made of an elastic material, such as a torsion spring, a leaf spring, an elastic gasket or a spring, etc. In this embodiment, an elastic gasket is used.

[0057] The pressing portion 121 is located in the accommodating cavity 110a and extends out through the pressing opening 110b. The pressing portion 121 moves under the action of an external force, allowing the hook 120 to be stably connected to or released from the charging port of the electric vehicle.

[0058] The buckle portion 122 is disposed on the pressing portion 121, extending out of the accommodating cavity 110a and capable of being engaged with the electric vehicle, thereby ensuring a stable physical connection between the charging gun 140 and the vehicle and preventing accidental detachment during the charging process.

[0059] The elastic member 130 is located in the accommodating cavity 110a, and its two ends are respectively against the accommodating cavity 110a and the pressing portion 121. The elastic member 130 provides necessary elastic force to support the reset of the pressing portion 121 and to provide further movement space for the pressing portion 121, and to further provide rotation space and rotation angle for the hook 120 after the buckle portion 122 is bent.

[0060] In at least one embodiment of the present application, the pressing portion 121 includes a pressing surface 121a and a mounting surface 121b away from the pressing surface 121a, and the mounting surface 121b is received in the accommodating cavity 110a;

[0061] The mounting surface 121 b defines a supporting groove 121 c , and one end of the elastic member 130 is received in the supporting groove 121 c and supported in the supporting groove 121 c .

[0062] Please refer to Figures 1 to 6 In this embodiment, when an external force acts on the pressing portion 121, the elastic member 130 located thereunder can be compressed. The pressing portion 121 is allowed to move further, increasing the rotation angle and space corresponding to the buckle portion 122.

[0063] The compression of the elastic member 130 through the force applied by the pressing portion 121 provides a larger rotation angle and space for the buckle portion 122 .

[0064] This makes it easier to insert into or remove from the charging port of the electric vehicle even after the buckle portion 122 is bent.

[0065] This makes the charging gun 140 more adaptable and can cope with slight bending of the buckle portion 122 caused by accident or long-term use, ensuring that the charging gun 140 can still be connected and disconnected smoothly.

[0066] Even when the buckle portion 122 is bent, the user can operate the charging gun 140 more easily, thereby improving the user experience.

[0067] The buckle portion 122 is allowed to continue to be used after being physically deformed to a certain extent, thereby extending the overall service life of the charging gun 140 and reducing the frequency of repair or replacement due to minor damage.

[0068] The durability and adaptability of the charging gun 140 are improved, thereby reducing the cost of long-term maintenance and replacement.

[0069] When the user applies force to the pressing surface 121a, the pressing portion 121 moves inward. One end of the elastic member 130 is fixed in the abutting groove 121c, so that a stable elastic response can be maintained. The further movement of the pressing portion 121 is achieved through the abutting groove 121c and the elastic member 130 on the mounting surface 121b, that is, the pressing portion 121 continues to press so that the abutting groove 121c applies a force to the elastic member 130, further compressing the elastic member 130 to increase the activity space of the pressing portion 121, so that the activity range of the buckle portion 122 is increased.

[0070] It should be noted that the pressing surface 121a is a side surface away from the housing 110 and is a convex arc surface; the mounting surface 121b is a plane away from the pressing surface 121a. The supporting groove 121c is a groove that is concave toward the pressing surface 121a.

[0071] One or more abutting grooves 121c are formed on the mounting surface 121b to accommodate and fix one end of the elastic member 130, so as to ensure that the elastic member 130 can provide a stable and consistent reaction force when a force is applied.

[0072] As the pressing portion 121 moves, the elastic member 130 is compressed, thereby accumulating energy. When the applied force is released, the elastic member 130 releases the stored energy, pushing the pressing portion 121 back to its original position, and the buckle portion 122 can be re-extended or maintained in its working position.

[0073] In at least one embodiment of the present application, one end of the pressing portion 121 away from the buckle portion 122 abuts against the elastic member 130 .

[0074] Please refer to Figures 1 to 7 In the present embodiment, one end of the pressing portion 121 away from the buckle portion 122 abuts against the elastic member 130 . When the user applies pressure to the pressing portion 121 , the end point directly abuts against the elastic member 130 , thereby pushing the elastic member 130 to be compressed.

[0075] The elastic member 130 stores energy. Once the pressure is released, the rebound force of the elastic member 130 pushes the pressing portion 121 back to the original position, and also affects the position and state of the buckle portion 122, such as promoting it to return to the locking or releasing position.

[0076] By ensuring that the reaction of the elastic member 130 is directly connected to the pressing action, the accuracy of the operation is increased, and the user can more accurately control the locking and releasing of the buckle portion 122, thereby improving the user experience.

[0077] Since the elastic member 130 directly abuts against a specific end point of the pressing portion 121 , the complexity of the structure and potential wear points are reduced, thereby improving the durability and reliability of the overall structure.

[0078] The user experience when connecting and disconnecting the charging gun 140 is smoother, reducing the inconvenience during operation, thereby directly improving the comfort of operation.

[0079] By directly abutting the elastic member 130 at the end of the pressing portion 121 away from the buckle portion 122, higher mechanical efficiency is achieved, allowing more direct force transmission, reducing energy loss, and making the operation smoother and more efficient.

[0080] In at least one embodiment of the present application, the pressing portion 121 is formed to protrude toward an end away from the housing 110 .

[0081] In at least one embodiment of the present application, the buckle portion 122 is protruded toward a side away from the pressing portion 121 , and the buckle portion 122 is bent inward toward a side close to the shell 110 .

[0082] Please refer to Figures 1 to 6 In this embodiment, the user initiates the disconnection action by applying force to the protruding pressing portion 121. The pressing action is transmitted to the buckle portion 122 through a mechanical connection or other transmission mechanism, causing it to move or adjust its position accordingly.

[0083] When the charging gun 140 needs to be connected, the inward bend of the buckle portion 122 ensures that it can be firmly inserted into the charging port of the electric vehicle, providing a safe and reliable connection. When disconnecting, the pressing portion 121 is operated again, and the buckle portion 122 is released from the locked position through mechanical action, so that it can be easily pulled out.

[0084] The protruding pressing portion 121 provides an easy-to-operate interface and an intuitive contact point for applying force.

[0085] The inward bend of the buckle portion 122 increases the stability and safety of the connection and reduces the risk of disconnection due to accidental collision or movement during charging.

[0086] The inward bend helps the buckle portion 122 provide additional locking force when inserted into the charging port of the electric vehicle, thereby ensuring the stability of the connection.

[0087] In at least one embodiment of the present application, in the pressing direction, the projection area of ​​the pressing portion 121 blocks the projection area of ​​the elastic member 130 .

[0088] Please refer to Figures 1 to 6 In this embodiment, when the user applies pressure to the pressing portion 121 , the pressing portion 121 directly acts on the elastic member 130 , so that the elastic member 130 is compressed. This ensures that the reaction force of the elastic member 130 directly supports the pressing portion 121 .

[0089] By making the projection area of ​​the pressing portion 121 shield the elastic member 130 , the elastic member 130 is protected from being directly exposed to the external environment to a certain extent, thereby reducing damage or malfunction that may be caused by external objects directly hitting the elastic member 130 .

[0090] In at least one embodiment of the present application, the hook 120 further includes:

[0091] The connecting rod portion 123 is disposed in the accommodating cavity 110 a , and the pressing portion 121 and the buckle portion 122 are respectively disposed at two ends of the connecting rod portion 123 .

[0092] In at least one embodiment of the present application, the connecting rod portion 123 is rotatably connected to the housing 110 .

[0093] In at least one embodiment of the present application, a rotation hole 110c is formed in the housing 110, and a rotation shaft 1231 is protruded from the connecting rod portion. The rotation shaft 1231 is movably received in the rotation hole 110c.

[0094] Please refer to Figures 1 to 6 In the present embodiment, when the user applies force to the pressing portion 121 , the force is transmitted through the connecting rod portion 123 , causing the buckle portion 122 to be unlocked from the charging port.

[0095] Since the connecting rod portion 123 and the housing 110 are rotatably connected via the rotating shaft 1231 and the rotating hole 110 c , the connecting rod portion 123 rotates smoothly during operation, thereby ensuring that the pressing action can be effectively converted into the unlocking action of the buckle portion 122 .

[0096] After the pressing portion 121 is released, the elastic structure 100 (such as the elastic member 130 or the recovery mechanism) may cause the link portion 123 to return to the original position.

[0097] Through the design of the rotating connection, the connecting rod portion 123 can rotate in the housing 110, making the operation smoother and reducing the loss or failure that may be caused by the fixed connection.

[0098] The rotating shaft 1231 and the rotating hole 110 c reduce friction and wear, extend the service life of the charging gun 140 , and maintain consistency and accuracy of operation.

[0099] It should be noted that the rotating hole 110 c is a circular hole, there are two rotating holes 110 c, the rotating shaft 1231 is a circular rod, the connecting rod portion 123 is a long rod, and the connecting rod portion 123 is used to connect the pressing portion 121 and the buckle portion 122 .

[0100] The connecting rod portion 123 is connected to the housing 110 through a rotational connection. Allowing the connecting rod portion 123 to rotate in the housing 110 provides a dynamic connection method to adapt to the movement requirements of the pressing portion 121 and the buckle portion 122.

[0101] A rotation hole 110c is provided in the housing 110, and correspondingly, a rotation shaft 1231 protrudes from the connecting rod portion of the connecting rod portion 123. The rotation shaft 1231 is movably received in the rotation hole 110c, allowing the connecting rod portion 123 to rotate freely within a certain range.

[0102] In at least one embodiment of the present application, the contact switch 150 is disposed between the pressing portion 121 and the elastic member 130 .

[0103] Please refer to Figures 1 to 6 In the present embodiment, when the user applies force to the pressing portion 121 , the force is transmitted through the connecting rod portion 123 , causing the buckle portion 122 to be unlocked from the charging port.

[0104] Since the connecting rod portion 123 and the housing 110 are rotatably connected via the rotating shaft 1231 and the rotating hole 110 c , the connecting rod portion 123 rotates smoothly during operation, thereby ensuring that the pressing action can be effectively converted into the unlocking action of the buckle portion 122 .

[0105] After the pressing portion 121 is released, the elastic structure 100 (such as the elastic member 130 or the recovery mechanism) may cause the link portion 123 to return to the original position.

[0106] Through the design of the rotating connection, the connecting rod portion 123 can rotate in the housing 110, making the operation smoother and reducing the loss or failure that may be caused by the fixed connection.

[0107] The rotating shaft 1231 and the rotating hole 110 c reduce friction and wear, extend the service life of the charging gun 140 , and maintain consistency and accuracy of operation.

[0108] In this embodiment, by providing the contact switch 150 between the pressing portion 121 and the elastic member 130, when the pressing portion 121 moves toward the direction approaching the contact switch 150, when the pressing portion 121 contacts the contact switch 150 to trigger the contact switch 150, the elastic member 130 at the bottom of the contact switch 150 plays a buffering role, protecting the contact switch 150 from damage due to excessive pressure, ensuring a smooth operation feel, and reducing the feeling of hard collision.

[0109] The buffering effect of the elastic member 130 reduces the physical loss of the contact switch 150 and prolongs the operating life of the device.

[0110] By reducing the impact on the contact switch 150, the failure rate due to excessive force is reduced, and the overall reliability of the device is increased.

[0111] The contact switch 150 is placed between the pressing portion 121 and the elastic member 130. The main function is to detect the pressure change when the pressing portion 121 is operated, and open or close the circuit accordingly, thereby triggering a specific action or feedback.

[0112] When no external force acts on the pressing portion 121, the contact switch 150 remains in its default state, and the circuit of the contact switch 150 is disconnected. The user applies force to the pressing portion 121, so that the pressing portion 121 moves toward the elastic member 130. As a result, the contact switch 150 is activated, and then its state is changed (e.g., from open to closed).

[0113] The change in state of the contact switch 150 causes the circuit to be closed or opened, triggering the corresponding function.

[0114] This may include starting the charging process, activating a display to show charging status, or other functions related to charging operations.

[0115] When the user stops applying force, the reaction force of the elastic member 130 returns the pressing portion 121 to the initial position, and the contact switch 150 also returns to its default state, ready for the next operation.

[0116] An embodiment of the present application provides a charging gun 140 , comprising any of the elastic structures 100 described above.

[0117] Please refer to Figures 1 to 6 In this embodiment, the user presses the pressing portion 121 downward, and the action is transmitted through the connecting rod portion 123, causing the buckle portion 122 to change from a locked state to an unlocked state, thereby allowing the charging gun 140 to be pulled out of the charging port of the electric vehicle.

[0118] After the unlocking action is completed, when the user releases the pressing portion 121 , the force of the elastic member 130 pushes the pressing portion 121 back to its original position, preparing for the next operation.

[0119] The charging gun 140 is allowed to continue to be used after the buckle portion 122 is slightly deformed due to inevitable falling and collision, thereby enhancing the durability and adaptability of the product.

[0120] Because the buckle portion 122 can still be used even after being slightly bent, the need for repair or replacement due to damage is reduced.

[0121] Through the elastic mechanism, the buckle portion 122 is allowed to continue to maintain its functionality after experiencing physical impact and slight deformation, by increasing the rotation angle and space of the charging gun 140 , thereby improving the durability of the entire charging gun 140 .

[0122] Initial state: The charging gun 140 is connected to the charging port of the electric vehicle. The buckle portion 122 is firmly engaged with the charging port through its locking mechanism to ensure the stability and safety of the charging process. At this time, the pressing portion 121 is in its original position, and the elastic member 130 is not compressed and is in a relaxed state.

[0123] The user applies a downward force to the pressing portion 121 of the charging gun 140 . This force is directly transmitted to the buckle portion 122 via the connecting rod portion 123 .

[0124] Due to the action of the link portion 123 , the buckle portion 122 moves from the locking position to the unlocking position, thereby driving the buckle portion 122 to move.

[0125] As the pressing portion 121 is pressed downward, the elastic member 130 connected thereto is compressed, storing a certain amount of energy, and preparing for the subsequent resetting process.

[0126] The buckle portion 122 moves to the unlocked position, and the charging gun 140 can be pulled out from the charging port of the electric vehicle. This process is fast and smooth, providing convenience for the user.

[0127] When the user stops applying force, the pressing portion 121 starts to move upward and returns to its initial position, mainly driven by the elastic force of the elastic member 130, which releases the stored energy and pushes the pressing portion 121 and the connecting rod portion 123 to move upward.

[0128] As the pressing portion 121 is reset, the buckle portion 122 also moves back to the position ready for locking. At this time, the charging gun 140 is ready for the next connection operation.

[0129] The elastic structure 100 allows the buckle portion 122 to be effectively inserted and removed from the charging port of the electric vehicle after being slightly bent. The elastic structure 100 provides a certain degree of adjustment space so that the buckle portion 122 can still match the charging port even after a slight change in shape.

[0130] After the mechanical hook is lifted to a certain height in accordance with the J1772 standard, the contact switch must be triggered so that the limit stroke of the contact switch is not exceeded and the switch is damaged. Then the hook is dropped to restore the contact switch to its initial position. The charging gun detects the moment the contact switch is closed and starts charging to charge the electric vehicle, thus avoiding damage to the charging gun due to plugging and unplugging.

[0131] It should be noted that if the buckle portion 122 is deformed during use (the buckle portion 122 is concavely deformed due to impact), when the pressing portion 121 is pressed, the pressing portion 121 will rotate relative to the rotating shaft 1231, thereby moving downward and abutting against the contact switch 150, driving the contact switch 150 to continue to move downward (towards the direction of the elastic member 130). Due to the presence of the elastic member 130, the pressing portion 121 can continue to move downward to increase the height of the buckle portion 122, while preventing the electric shock switch 150 from being damaged due to excessive pressing stroke of the pressing portion 121.

[0132] In another embodiment, a limit point (not marked in the figure) is provided in the charging gun 140. When the pressing portion 121 is pressed, the pressing portion 121 abuts against the contact switch 150, driving the contact switch 150 to continue to move downward (in the direction close to the elastic member 130). Due to the presence of the elastic member 130, the pressing portion 121 can continue to move downward to increase the height of the buckle portion 122. At the same time, the limit point can limit the downward movement of the pressing portion 121, thereby avoiding the problem of damage to the contact switch 150 caused by excessive movement of the pressing portion 121 in the direction close to the elastic member 130.

[0133] By ensuring that the buckle portion 122 can still be used normally after being slightly deformed, the interruption of use caused by damage to the buckle portion 122 is greatly reduced, thereby improving the overall user experience.

[0134] By improving the adaptability of the buckle portion 122 , frequent replacement due to accidental damage is reduced, thereby reducing the overall cost during long-term use.

[0135] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
