DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0032] Please refer to Figures 1 to 7 In the embodiments of the utility model, an improved power converter comprises a separation plug 10 and a power supply body 40, the separation plug 10 is detachably connected to the power supply body 40 and forms an electrical connection, so that the power supply body 40 can be connected to external power supply and output electric energy; one end of the separation plug 10 connected to the power supply body 40 is provided with a counterbore slot 11, one end of the power supply body 40 corresponding to the counterbore slot 11 is provided with an adapter ring 41, the adapter ring 41 can be inserted into the counterbore slot 11 to form an adapter, one end of the adapter ring 41 is fixed to the power supply body 40, and the outer side wall of the other end is provided with a buckle block 42, the inner side wall of the counterbore slot 11 is provided with a buckle groove 12 at a position close to the bottom of the slot, the buckle block 42 can be embedded in the buckle groove 12, so that the inner side wall above the buckle groove 12 can buckle the buckle block 42, and the separation plug 10 and the power supply body 40 are buckled with each other to form an integrated power converter.

[0033] Specifically, the power supply body 40 of the power converter and the separation plug 10 can be detached and replaced, different separation plugs 10 can be replaced according to different use environments or use areas, only the separation plug 10 of the Australian standard is used in the utility model for description, but it can be understood that the input plug 30 part of the separation plug 10 can also be set according to the power plug regulations of different regions, so as to be suitable for different regions for power connection.

[0034] Secondly, when the corresponding specification of the separate plug 10 is needed, the separate plug 10 can be connected to the power supply body 40 for use. When the adapter ring 41 is inserted into the counterbore groove 11 and rotated by a predetermined angle, the buckle protrusion 42 provided on the adapter ring 41 can be embedded into the buckle groove 12 in the counterbore groove 11, and they can be matched with each other to achieve the state of buckling connection. At the same time, the adapter spring sheet 31 of the separate plug 10 and the adapter terminal 50 of the power supply body 40 can be in abutting state to form electrical connection, so that the transmission of electric energy can be realized to achieve the function of power conversion.

[0035] As shown in Figure 3 and Figure 5 Preferably, the inner side wall of the counterbore groove 11 is provided with a first notch 13 corresponding to the starting end of the buckle groove 12, and the first notch 13 is in communication with the buckle groove 12, so that the buckle protrusion 42 can be inserted into the buckle groove 12 through the first notch 13.

[0036] Specifically, the first notch 13 is a recessed notch extending along the radial direction of the separate plug 10 and towards the outer side wall of the separate plug 10, so that when the adapter ring 41 is inserted in the direction of the counterbore groove 11, the buckle protrusion 42 is located in the recessed notch of the first notch 13, so that it can be smoothly inserted into the starting end of the buckle groove 12. Then, the adapter ring 41 is rotated by a predetermined angle, so that the buckle protrusion 42 can be buckled into the buckle groove 12, so that the top wall of the buckle groove 12 can limit the buckle protrusion 42. The bottom of the side wall of the counterbore groove 11 is hollowed out to a certain depth, and the part of the top which is not hollowed out forms the part limiting the buckle protrusion 42.

[0037] As shown in Figures 4 to 6 Preferably, the side of the buckle protrusion 42 protruding outward is provided with an arc-shaped recess 43, which is recessed inward to a certain depth, so that the buckle protrusion 42 forms an M-shaped protruding structure; the end of the buckle groove 12 is provided with a limiting protrusion 14, and the limiting protrusion 14 and the arc-shaped recess 43 are matched with each other, so that the limiting protrusion 14 can be embedded into the arc-shaped recess 43, thereby limiting the buckle protrusion 42.

[0038] Specifically, when the adapter ring 41 is inserted into the counterbore groove 11 and rotated by a certain angle, the buckle protrusion 42 passes through the first notch 13 and enters the inside of the buckle groove 12, and after rotating by a certain angle along the buckle groove 12, the limiting protrusion 14 can be embedded into the arc-shaped recess 43 of the buckle protrusion 42, so that the limiting protrusion 14 can limit the buckle protrusion 42 to a certain extent, and the rotation of the adapter ring 41 is resisted to a certain extent, so that the adapter ring 41 can be more stably inserted into the counterbore groove 11.

[0039] As Figure 4 shown, preferably, the separation plug 10 is provided with a first deformation member 15 corresponding to the position of the limiting protrusion 14, one end of the first deformation member 15 is fixedly connected to the separation plug 10, and the other end forms a free end, the limiting protrusion 14 is arranged at the free end of the first deformation member 15, and under the deformation elastic force of the first deformation member 15, the limiting connection is formed to the arc-shaped recess 43 of the buckle protrusion 42.

[0040] Specifically, in order to make one side of the M-shaped tip of the buckle protrusion 42 can pass through the limiting protrusion 14, it is preferred that the first deformation member 15 is arranged at the position of the limiting protrusion 14, so that the limiting protrusion 14 can be deformed outwardly after receiving the extrusion of the buckle protrusion 42, so that the buckle protrusion 42 can move outwardly by a certain distance, so that the one side of the tip of the buckle protrusion 42 can pass through the limiting protrusion 14, and the limiting protrusion 14 is just clamped into the arc-shaped recess 43 of the buckle protrusion 42. When disassembly is needed, a certain torsion force needs to be applied to the adapter ring 41 to overcome the limitation of the limiting protrusion 14, so that the adapter ring 41 can be rotated and disassembled.

[0041] As Figure 4 and Figure 6 shown, preferably, the adapter ring 41 is provided with two half rings 44 which are symmetrically distributed at a certain distance from each other, and the two half rings 44 are the same in structure, one end of the half ring 44 is fixedly connected to the power body 40, and the other end forms a free end which can be deformed, and is provided with a locking protrusion 45; the inner side wall of the counterbore groove 11 is provided with a first through hole 16, and the locking protrusion 45 can be embedded into the first through hole 16, so as to limit the rotation of the adapter ring 41 in the counterbore groove 11.

[0042] Specifically, when the adapter ring 41 of the power body 40 is inserted into the counterbore groove 11 of the separation plug 10, the power body 40 can be rotated by a certain angle, so that the adapter ring 41 is synchronously rotated by a certain angle in the counterbore groove 11, so that the locking protrusion 45 can be embedded into the first through hole 16, so that the side wall of the first through hole 16 can limit the locking protrusion 45, so that the adapter ring 41 cannot continue to rotate in the counterbore groove 11. It is equivalent to locking the adapter ring 41 and the counterbore groove 11, further improving the stability of the adapter state between them.

[0043] As Figures 1 to 5As shown, preferably, the disconnecting plug 10 is further provided with an unlocking button 20 and an unlocking spring 23. The outer wall of the disconnecting plug 10 is provided with a second through hole 17. The unlocking button 20 is movably connected to the disconnecting plug 10, with one end penetrating the first through hole 16 and the other end provided with a key cap 21 and protruding from the second through hole 17 by a certain length. One end of the unlocking spring 23 abuts against the disconnecting plug 10 and the other end abuts against the key cap 21 of the unlocking button 20, so that the elastic force of the unlocking spring 23 drives the unlocking button 20 to keep protruding outward.

[0044] Specifically, in order to detach the adapter state between the disconnecting plug 10 and the power body 40, the adapter ring 41 needs to be rotated in the opposite direction. However, the locking protrusion 45 is embedded in the first through hole 16 and is limited by the side wall of the first through hole 16, so that the adapter ring 41 cannot be rotated in the opposite direction. Therefore, the locking protrusion 45 needs to be pressed to make the free end of the half ring 44 in which the locking protrusion 45 is located to be deformed to a certain extent to bend inward, so that the locking protrusion 45 is detached from the first through hole 16 and no longer limits the rotation of the adapter ring 41. Therefore, the second through hole 17 can be arranged on the side wall of the disconnecting plug 10, and the unlocking button 20 can be arranged in the second through hole 17, so that one end of the unlocking button 20 can penetrate the first through hole 16 and abut against the locking protrusion 45 in the first through hole 16. By pressing the key cap 21 of the unlocking button 20, the unlocking button 20 can be moved inward by a certain distance and press the locking protrusion 45, so that the free end of the half ring 44 is deformed to a certain extent to bend inward, and then the locking protrusion 45 is detached from the first through hole 16. At the same time, the power body 40 can be rotated to make the adapter ring 41 rotate in the opposite direction, and then the disconnecting plug 10 is detached from the sink hole 11.

[0045] Secondly, in order to prevent the unlocking button 20 from being pushed out by the elastic force of the unlocking spring 23, the anti-extrusion ring 22 can be arranged on the part of the key cap 21 inside the side wall of the disconnecting plug 10. The anti-extrusion ring 22 can abut against the inner side of the side wall from the inside of the disconnecting plug 10, so as not to be pushed out.

[0046] In addition, under the extrusion of the unlocking button 20, the free end of the half ring 44 where the locking protrusion 45 is located is deformed to a certain extent, so that the locking protrusion 45 is separated from the first through hole 16, the unlocking operation is realized, and the adapter ring 41 can rotate in the counterbore groove 11. Since the locking protrusion 45 protrudes from the half ring 44, it will abut against the inner side wall of the counterbore groove 11. If it is directly pulled out, scratches will be easily formed on the top area of the inner side wall of the counterbore groove 11, affecting the appearance. Therefore, a second notch 18 can be further arranged on the inner side wall of the counterbore groove 11, so that the adapter ring 41 rotates to a certain angle, and when it needs to be pulled out, the locking protrusion 45 is located in the second notch 18, facilitating the pulling out and avoiding scratches. Of course, when the locking protrusion 45 rotates at the bottom of the adapter ring 41, it can also cause scratches on the inner side wall of the adapter ring 41, but the bottom is relatively difficult to observe and relatively does not affect the appearance.

[0047] As shown in Figure 2 and Figure 3 Preferably, the power supply body 40 is further provided with an adapter terminal 50, a circuit board 51 and an output port 52 which are electrically connected with each other. The output port 52 is used for external power output. The adapter terminal 50 is fixedly connected to the side wall of the power supply body 40 surrounded by the adapter ring 41, one end of which is arranged in the power supply body 40 and is electrically connected with the circuit board 51, and the other end is arranged outside the position surrounded by the adapter ring 41 to form a free end. The adapter terminal 50 is used for electrically connecting the separate plug 10. The separate plug 10 is provided with an input plug 30 and an adapter spring 31 which are electrically connected with each other. One end of the input plug 30 is fixedly connected to the separate plug 10, and the other end is used for plugging into an external socket to input power. One end of the adapter spring 31 is fixedly connected to the input plug 30, and the other end forms a free end with a certain elasticity, so as to abut against the adapter terminal 50 of the power supply body 40 when the adapter ring 41 is inserted into the counterbore groove 11, so that the two are electrically connected.

[0048] Specifically, the circuit board 51 can also be provided with corresponding voltage conversion circuit, current limiting circuit, power management chip and other existing electronic circuits or electronic components as needed, so as to realize the corresponding functions of a complete power converter. The output port 52 can also be provided with corresponding USB-A, TYPE-C and other universal interfaces as needed.

[0049] As shown in Figures 5 to 7 Preferably, the counterbore groove 11 is provided with a fan-shaped hole column 32 corresponding to the position of the adapter terminal 50. The fan-shaped hole column 32 protrudes upward from the bottom of the counterbore groove 11 to a certain length, and is hollow inside to form a fan-shaped through hole for accommodating the adapter terminal 50.

[0050] Specifically, in order to improve the safety, preferably, the fan-shaped hole column 32 is arranged at the bottom of the counterbore groove 11, and protrudes for a certain length, so as to avoid accidentally contacting the adapter spring 31 inside the separate plug 10, causing electric shock. Since the adapter ring 41 needs to be rotated by a certain angle to be locked when being inserted into the counterbore groove 11, the inner hollow of the fan-shaped hole column 32 can form a fan-shaped through hole, so that the adapter terminal 50 of the adapter ring 41 can be rotated by a certain angle along the side wall of the fan-shaped through hole after being inserted into the inner hollow of the fan-shaped hole column 32. At the same time, the front section of the adapter terminal 50 can form abutment with the adapter spring 31 inside the separate plug 10 after being inserted into the fan-shaped hole column 32, and form an abutment state of close adhesion with each other by the elastic force of the adapter spring 31, so as to realize the transmission of electric energy. Please refer to Figures 1 to 7 In the embodiment of the utility model, an improved power converter includes a separate plug 10 and a power body 40, the separate plug 10 is detachably connected to the power body 40 and forms an electrical connection, so that the power body 40 can be connected to external power supply and output electric energy; one end of the separate plug 10 is provided with a counterbore groove 11, and the power body 40 is provided with an adapter ring 41 corresponding to one end of the counterbore groove 11, the adapter ring 41 can be inserted into the counterbore groove 11 to form an adapter, one end of the adapter ring 41 is fixed to the power body 40, and the outer side wall of the other end is provided with a buckle protrusion 42, the inner side wall of the counterbore groove 11 is provided with a buckle groove 12 corresponding to the position close to the bottom of the groove, the buckle protrusion 42 can be embedded in the inner part of the buckle groove 12, so that the inner side wall corresponding to the upper part of the buckle groove 12 can form a buckle connection with the buckle protrusion 42, and then the separate plug 10 and the power body 40 are buckled with each other to form an integrated power converter.

[0051] Specifically, the power body 40 of the power converter and the separate plug 10 can be detachably replaced, different separate plugs 10 can be replaced according to different use environments or use areas, and only the Australian separate plug 10 is used for illustration in the utility model, but it can be understood that the input plug 30 part of the separate plug 10 can also be set according to the power plug regulations of different regions, so as to be suitable for different regions for power connection.

[0052] Secondly, when a breakaway plug 10 of the corresponding specifications is needed, the breakaway plug 10 can be connected to the power supply body 40 for use. When the adapter ring 41 is inserted into the countersunk groove 11 and rotated a predetermined angle, the snap-fit ​​protrusions 42 on the adapter ring 41 fit neatly into the snap-fit ​​grooves 12 within the countersunk groove 11, mating with each other to achieve a snap-fit ​​connection. At the same time, the adapter spring 31 of the breakaway plug 10 and the adapter terminal 50 of the power supply body 40 can be brought into contact with each other, thereby establishing an electrical connection, enabling the transmission of electrical energy and realizing the power conversion function.

[0053] like Figure 3 and Figure 5 As shown, preferably, the inner wall of the countersunk groove 11 is provided with a first notch 13 corresponding to the starting end of the snap groove 12, and the first notch 13 is connected to the snap groove 12, so that the snap protrusion 42 can be inserted into the inside of the snap groove 12 through the first notch 13.

[0054] Specifically, the first notch 13 is a recessed notch extending radially along the separation plug 10 and toward the outer wall of the separation plug 10. This allows the adapter ring 41 to be inserted into the countersunk groove 11 with the snap-on protrusion 42 positioned within the recessed notch of the first notch 13, allowing it to be smoothly inserted into the starting end of the snap-on groove 12. The adapter ring 41 is then rotated by a preset angle so that the snap-on protrusion 42 snaps into the snap-on groove 12, allowing the top wall of the snap-on groove 12 to restrain the snap-on protrusion 42. This is equivalent to hollowing out the bottom of the side wall of the countersunk groove 11 to form a recessed notch of a certain depth, while the top portion, which remains unhollowed, forms a portion that restrains the snap-on protrusion 42.

[0055] like Figures 4 to 6 As shown, preferably, an arc-shaped pit 43 is provided on the side of the snap-on protrusion 42 that protrudes outward, and the arc-shaped pit 43 is recessed inward to a certain depth, so that the snap-on protrusion 42 forms an M-shaped protruding structure; a limiting boss 14 is provided at the tail end of the snap-on groove 12, and the limiting boss 14 cooperates with the arc-shaped pit 43 so that the limiting boss 14 can be embedded in the arc-shaped pit 43, thereby forming a limiting connection for the snap-on protrusion 42.

[0056] Specifically, when the adapter ring 41 is inserted into the countersunk groove 11 and rotated at a certain angle, so that the snap protrusion 42 passes through the first notch 13 and enters the inside of the snap groove 12, and after synchronously rotating at a certain angle along the snap groove 12, the limiting boss 14 can be embedded in the arc-shaped pit 43 of the snap protrusion 42, so that the limiting boss 14 can form a certain limiting effect on the snap protrusion 42, and form a certain resistance to the rotation of the adapter ring 41, so that the adapter ring 41 can be more firmly inserted into the countersunk groove 11.

[0057] As Figure 4 shown, preferably, the separation plug 10 is provided with a first deformation member 15 corresponding to the position of the limiting protrusion 14, one end of the first deformation member 15 is fixedly connected to the separation plug 10, and the other end forms a free end, the limiting protrusion 14 is arranged at the free end of the first deformation member 15, and under the deformation elastic force of the first deformation member 15, the limiting connection is formed to the arc-shaped recess 43 of the buckle protrusion 42.

[0058] Specifically, in order to make one side of the M-shaped tip of the buckle protrusion 42 can pass through the limiting protrusion 14, it is preferred that the first deformation member 15 is arranged at the position of the limiting protrusion 14, so that the limiting protrusion 14 can be deformed outwardly after receiving the extrusion of the buckle protrusion 42, so that the limiting protrusion moves outwardly by a certain distance, so that one side of the tip of the buckle protrusion 42 can pass through the limiting protrusion 14, and the limiting protrusion 14 is just clamped into the arc-shaped recess 43 of the buckle protrusion 42. When disassembly is needed, a certain torsion force needs to be applied to the adapter ring 41 to make it overcome the limitation of the limiting protrusion 14, so as to rotate the adapter ring 41 and disassemble it.

[0059] As Figure 4 and Figure 6 shown, preferably, the adapter ring 41 is provided with two half rings 44 which are symmetrically distributed at a certain distance from each other, and the two half rings 44 are the same in structure, one end of the half ring 44 is fixedly connected to the power body 40, and the other end forms a free end which can be deformed, and is provided with a locking protrusion 45; the inner side wall of the counterbore groove 11 is provided with a first through hole 16, and the locking protrusion 45 can be embedded into the first through hole 16, so as to limit the rotation of the adapter ring 41 in the counterbore groove 11.

[0060] Specifically, when the adapter ring 41 of the power body 40 is inserted into the counterbore groove 11 of the separation plug 10, the power body 40 can be rotated by a certain angle, so that the adapter ring 41 is synchronously rotated by a certain angle in the counterbore groove 11, so that the locking protrusion 45 can be embedded into the first through hole 16, so that the side wall of the first through hole 16 can limit the locking protrusion 45, so that the adapter ring 41 cannot continue to rotate in the counterbore groove 11. It is equivalent to locking the adapter ring 41 and the counterbore groove 11, further improving the stability of the adapter state between them.

[0061] As Figures 1 to 5As shown, preferably, the disconnecting plug 10 is further provided with an unlocking button 20 and an unlocking spring 23. The outer wall of the disconnecting plug 10 is provided with a second through hole 17. The unlocking button 20 is movably connected to the disconnecting plug 10, with one end penetrating the first through hole 16 and the other end provided with a key cap 21 and protruding from the second through hole 17 by a certain length. One end of the unlocking spring 23 abuts against the disconnecting plug 10 and the other end abuts against the key cap 21 of the unlocking button 20, so that the elastic force of the unlocking spring 23 drives the unlocking button 20 to keep protruding outward.

[0062] Specifically, in order to detach the adapter state between the disconnecting plug 10 and the power body 40, the adapter ring 41 needs to be rotated in the opposite direction. However, the locking protrusion 45 is embedded in the first through hole 16 and is limited by the side wall of the first through hole 16, so that the adapter ring 41 cannot be rotated in the opposite direction. Therefore, the locking protrusion 45 needs to be pressed to make the free end of the half ring 44 in which the locking protrusion 45 is located to be deformed to a certain extent by bending inward, so that the locking protrusion 45 is detached from the first through hole 16 and no longer limits the rotation of the adapter ring 41. Therefore, the second through hole 17 can be arranged on the side wall of the disconnecting plug 10, and the unlocking button 20 can be arranged in the second through hole 17, so that one end of the unlocking button 20 can penetrate the first through hole 16 and abut against the locking protrusion 45 in the first through hole 16. By pressing the key cap 21 part of the unlocking button 20, the unlocking button 20 can be moved inward by a certain distance and press the locking protrusion 45, so that the free end of the half ring 44 is deformed to a certain extent by bending inward, and then the locking protrusion 45 is detached from the first through hole 16. At the same time, the power body 40 can be rotated to make the adapter ring 41 rotate in the opposite direction, and then be detached from the sink hole 11.

[0063] Secondly, in order to prevent the unlocking button 20 from being pushed out by the elastic force of the unlocking spring 23, the anti-extrusion ring 22 can be arranged on the part of the key cap 21 inside the side wall of the disconnecting plug 10. The anti-extrusion ring 22 can abut against the inner side of the side wall from the inside of the disconnecting plug 10, so as not to be pushed out.

[0064] In addition, under the extrusion of the unlocking button 20, the free end of the half ring 44 where the locking protrusion 45 is located is deformed to a certain extent, so that the locking protrusion 45 is separated from the first through hole 16, the unlocking operation is realized, and the adapter ring 41 can rotate in the counterbore groove 11. Since the locking protrusion 45 protrudes from the half ring 44, it will abut against the inner side wall of the counterbore groove 11. If it is directly pulled out, scratches will be easily formed on the top area of the inner side wall of the counterbore groove 11, affecting the appearance. Therefore, a second notch 18 can be further arranged on the inner side wall of the counterbore groove 11, so that the adapter ring 41 rotates to a certain angle, and when it needs to be pulled out, the locking protrusion 45 is located in the second notch 18, facilitating the pulling out and avoiding scratches. Of course, when the locking protrusion 45 rotates at the bottom of the adapter ring 41, it can also cause scratches on the inner side wall of the adapter ring 41, but the bottom is relatively difficult to observe and relatively does not affect the appearance.

[0065] As shown in Figure 2 and Figure 3 Preferably, the power supply body 40 is further provided with an adapter terminal 50, a circuit board 51 and an output port 52 which are electrically connected with each other. The output port 52 is used for external power output. The adapter terminal 50 is fixedly connected to the side wall of the power supply body 40 surrounded by the adapter ring 41, one end of which is arranged in the power supply body 40 and is electrically connected with the circuit board 51, and the other end is arranged outside the position surrounded by the adapter ring 41 to form a free end. The adapter terminal 50 is used for electrically connecting the separate plug 10. The separate plug 10 is provided with an input plug 30 and an adapter spring 31 which are electrically connected with each other. One end of the input plug 30 is fixedly connected to the separate plug 10, and the other end is used for plugging into an external socket to input power. One end of the adapter spring 31 is fixedly connected to the input plug 30, and the other end forms a free end with a certain elasticity, so as to abut against the adapter terminal 50 of the power supply body 40 when the adapter ring 41 is inserted into the counterbore groove 11, so that the two are electrically connected.

[0066] Specifically, the circuit board 51 can also be provided with corresponding voltage conversion circuit, current limiting circuit, power management chip and other existing electronic circuits or electronic components as needed, so as to realize the corresponding functions of a complete power converter. The output port 52 can also be provided with corresponding USB-A, TYPE-C and other universal interfaces as needed.

[0067] As shown in Figures 5 to 7 Preferably, the counterbore groove 11 is provided with a fan-shaped hole column 32 corresponding to the position of the adapter terminal 50. The fan-shaped hole column 32 protrudes upward from the bottom of the counterbore groove 11 to a certain length, and is hollow inside to form a fan-shaped through hole for accommodating the adapter terminal 50.

[0068] Specifically, in order to improve safety, preferably, the fan-shaped hole column 32 is arranged at the bottom of the counterbore groove 11 and protrudes a certain length, thereby avoiding unintentional contact with the adapter spring 31 inside the separate plug 10, resulting in electric shock. Since the adapter ring 41 needs to be rotated at a certain angle to be locked when inserted into the counterbore groove 11, the inside of the fan-shaped hole column 32 is hollow, which can form a fan-shaped through hole, so that the adapter terminal 50 of the adapter ring 41 can be rotated at a certain angle along the side wall of the fan-shaped through hole after being inserted into the inside of the fan-shaped hole column 32. At the same time, the front section of the adapter terminal 50 can form abutment with the adapter spring 31 inside the separate plug 10 after being inserted into the fan-shaped hole column 32, and form an abutment state of close adhesion with each other by the elastic force of the adapter spring 31, thereby realizing the transmission of electric energy.

[0069] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
