Description

Electric operating device

[0001] This application is based on and claims priority to Chinese Patent Application No. 202411758624.X, filed on December 3, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to an electrically operated device. Background Technology

[0003] Traditional miniature circuit breakers require manual operation for opening and closing. With the development of smart grids, there is an urgent need for miniature circuit breaker products that can reliably achieve automatic opening and closing. Therefore, electrically operated devices have emerged on the market that work with miniature circuit breakers to drive their opening and closing actions. By sending commands to these devices, the miniature circuit breaker can be remotely driven to automatically open and close without manual operation, effectively saving manpower and resources, and their applications are becoming increasingly widespread.

[0004] However, electric operation alone cannot solve all the problems.

[0005] In view of this, it is necessary to improve the existing electric operating device to solve the above problems.

[0006] Any prior art mentioned in the specification does not imply confirmation or suggestion that such prior art constitutes part of the general common knowledge in any jurisdiction, or that it can be reasonably expected that such prior art will be understood, regarded as relevant and / or combined with other prior art by a person skilled in the art.

[0007] Application content

[0008] The purpose of this application is to provide an electric operating device to solve the problem that existing operating methods can only be operated manually or automatically.

[0009] To achieve the above objectives, this application provides an electrically operated device for driving a switch handle on a circuit breaker to open or close the circuit. The electrically operated device includes:

[0010] The housing includes a display cover disposed on one side;

[0011] The control panel is housed within the outer casing and is used to manually operate the switch handle.

[0012] A connecting component, which is disposed within the housing, is used to electrically drive the switch handle.

[0013] A control circuit board, which is electrically connected to the connection assembly to control the operation of the connection assembly;

[0014] A padlock plate has a padlock hole at one end near the display cover. The padlock plate has a retractable state and a padlocked state. When the padlock plate is in the retractable state, the padlock hole is located inside the outer casing. When the padlock plate is in the padlocked state, the padlock plate protrudes from the outer casing, and the padlock hole is exposed outside the outer casing.

[0015] As a further improvement of this application, the housing includes a first cover extending from the display cover toward one side and a second cover extending from the first cover toward the side away from the display cover, the second cover protruding horizontally from the first cover to form a mounting step.

[0016] As a further improvement of this application, the display cover is provided with a display hole, which is directly opposite the operation panel in the vertical direction. The electric operation device also includes a split-open indicator slide and a drive assembly. The split-open indicator slide is disposed between the operation panel and the display cover. The split-open indicator slide is provided with a display part and a through hole. The drive assembly is used to drive the split-open indicator slide to slide so that the display part or the through hole is located below the display hole.

[0017] As a further improvement of this application, the driving component includes an indicator push rod and an indicator rotation member. The indicator push rod and the indicator rotation member are both disposed on the side of the split indicator slide away from the display cover. The indicator push rod slides in a direction perpendicular to the split indicator slide, and the indicator rotation member is driven by the indicator push rod to move the split indicator slide in a horizontal direction.

[0018] As a further improvement of this application, when the circuit breaker is closed, the open / close indicator slide or indicator rotation element prevents the padlock plate from being hung up.

[0019] As a further improvement of this application, the connecting component includes a slider for connecting to the switch handle. The slider slides horizontally to drive the switch handle to rotate. When the circuit breaker is closed, the slider restricts the padlock plate from being hung up. When the padlock plate is locked, the padlock plate restricts the slider from sliding to restrict the circuit breaker from closing.

[0020] As a further improvement of this application, the electric operating device further includes a padlock baffle, which is slidably disposed in the horizontal direction. When the padlock is engaged, the padlock baffle blocks the space between the operating hole and the manual operating plate. When the circuit breaker is closed, the padlock baffle moves away from the operating hole and the manual operating plate in the horizontal direction.

[0021] As a further improvement of this application, the display cover is provided with an operation hole, and the electric operation device further includes a manual operation plate. The manual operation plate is provided with an exposure groove. The manual operation plate is disposed between the display cover and the operation panel.

When the manual operation plate is in the second position, the exposure groove is located between the operation hole and the manual operation plate.

[0022] As a further improvement of this application, the control circuit board is provided with a switching power supply, a power conversion circuit, a sampling switch and circuit, and a control circuit.

[0023] As a further improvement of this application, the connecting assembly further includes a drive motor, a gear set, and a cam. The gear set connects the drive motor and the cam, and the cam connects the gear set and the slider. The drive motor drives the gear set to rotate, thereby driving the cam to rotate, and the cam drives the slider to move.

[0024] The beneficial effects of this application are: the electric operating device of this application can realize electric automatic control as well as manual control, has a compact structure, is easy to use, and is highly safe.

[0025] The term “comprise” as used herein, and variations thereof such as “comprises”, “comprised”, “comprising”, “including”, and “containing”, do not exclude other features, components, elements, or steps unless the context clearly requires otherwise. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0046] As shown in Figures 1 to 16, the electric operating device 100 of this application includes a housing 1, an operating panel 3, a connecting component 4, a control circuit board 5, a padlock plate 6, a padlock baffle 7, a manual operating panel 8, a linkage component 9, a plastic pad 10, a split / open indicator slide plate 101, and a drive component 102.

[0047] The electric operating device 100 is used to drive the switch handle 2 on the circuit breaker to open or close. The switch handle 2 is shown in the figure to facilitate understanding of the cooperation between the electric operating device 100 and the circuit breaker, and does not mean that the switch handle 2 belongs to the electric operating device 100.

[0048] As shown in Figures 1 to 4, the outer casing 1 includes a display cover 11 disposed on one side, a first cover 12 extending from the display cover 11 toward one side, and a second cover 13 extending from the first cover 12 toward the side away from the display cover 11. The second cover 13 protrudes horizontally from the first cover 12 to form an installation step 14.

[0049] The plastic liner 10 is located inside the outer casing 1.

[0050] In this embodiment, the direction perpendicular to the display cover 11 is defined as the vertical direction, the extension direction of the display cover 11 or parallel to the extension direction of the display cover 11 is defined as the horizontal direction, and the direction of the electric operating device 100 toward the display cover 11 is defined as upward, and the direction away from the display cover 11 is defined as downward. Such definitions do not represent the actual position relative to the ground during installation or use, and are not limited thereto.

[0051] The display cover 11 has a through-hole 111, an operation hole 112 and a moving groove 113; the lower side of the display cover 11 has an upwardly recessed track groove 114. In this embodiment, the track groove 114 does not penetrate the display cover 11, but this is not a limitation.

[0052] If an open-hole installation is used, in conjunction with a protective panel, the first cover 12 can protrude out of the protective panel to expose the display cover 11 and the outside of the mounting cabinet, while the second cover 13 is hidden inside the cabinet, and the mounting step 14 serves as a limit, thus improving the protection level.

[0053] The display cover 11 may also have an identification icon 115 on the outward-facing side to indicate the color, shape, etc., displayed from the display hole 111 corresponding to the state of the electric operating device 100. Generally, the electric operating device 100 has at least three states: ON, OFF, and TRIPED. The ON and OFF states correspond to the ON and OFF states of the circuit breaker and the electric operating device 100. When the circuit breaker is OFF, the electric operating device 100 may be in the TRIPED state, which will be understood by those skilled in the art and will not be elaborated here.

[0054] As shown in Figures 5 to 7, the operation panel 3 is disposed inside the outer casing 1 and is used to manually drive the connecting assembly 4. In this embodiment, the operation panel 3 is provided with a keyhole 31 for the user to insert a key to operate the circuit breaker opening and closing.

[0055] The operation hole 112 is located directly above the operation panel 3 to expose the keyhole 31.

[0056] As shown in Figures 1, 3, and 12, the manual operation panel 8 has an exposed groove 81 extending through it, and a hand-held protrusion 82 protrudes upward from the manual operation panel 8. The hand-held protrusion 82 is inserted vertically into the moving groove 113 and can be moved horizontally by the user's hand operation.

[0057] The manual control panel 8 is disposed between the display cover 11 and the control panel 3. The manual control panel 8 has a first position that is blocked between the control hole 112 and the manual control panel 8, and a second position that moves horizontally relative to the first state. When the manual control panel 8 is in the second position, the exposure groove 81 is located between the control hole 112 and the manual control panel 8. If the padlock baffle 7 is not blocking the exposure groove 81, the user can operate the control panel 3 through the exposure groove 81.

[0058] As shown in Figures 1-3, 6, and 14, the padlock plate 6 has a padlock hole 61 at one end near the display cover 11. The padlock plate 6 has a receiving state and a padlock state. When the padlock plate 6 is in the receiving state, the padlock hole 61 is located inside the outer shell 1. When the padlock plate 6 is in the padlock state, the padlock plate 6 protrudes from the outer shell 1, and the padlock hole 61 is exposed outside the outer shell 1.

[0059] The plastic pad 10 is provided with a reset plate 110, and the padlock plate 6 is provided with a reset spring 62. The reset spring 62 connects the padlock plate 6 and the reset plate 110. When the padlock plate 6 protrudes from the outer shell 1, the reset spring 62 is in a stretched state. When the external force is lost, the reset spring 62 can drive the padlock plate 6 to automatically return to the retracted state.

[0060] The padlock plate 6 is provided with a hook 63 protruding from it, and one end of the reset spring 62 is engaged with the hook 63.

[0061] The padlock plate 6 is provided with a guide groove 64 extending in a vertical direction, and the plastic liner 10 is provided with a guide portion 120 protruding through the guide groove 64. The end of the guide portion 120 is larger than the width of the guide groove 64 to prevent the guide portion 120 from detaching from the padlock plate 6.

[0062] One end of the guide groove 64 is provided with a mounting hole 641 through which the guide part 120 passes. When the guide part 120 is installed, the guide part 120 passes through the mounting hole 641.

[0063] In this embodiment, when the circuit breaker is closed, the padlock plate 6 is necessarily in a concealed state. When the circuit breaker is open, the padlock plate 6 may be in a concealed state or a locked state. Whether to lock or not needs to be selected by the user according to the actual situation. In order to achieve this effect, the following settings are made in this embodiment:

[0064] The padlock plate 6 has a retaining block 65 at the other end away from the padlock hole 61, wherein the padlock hole 61 is close to the display cover 11, and the retaining block 65 is away from the display cover 11.

[0065] The abutment block 65 is rotatably mounted relative to the padlock plate 6.

[0066] The connecting assembly 4 includes a drive motor 41, a gear set 42, a cam 43, a slider 44, and a slide rail 45. The connecting assembly 4 is used to electrically drive the switch handle 2 to operate.

[0067] As shown in Figures 5 to 9, the gear set 42 is connected to the drive motor 41 and the cam 43. The cam 43 is connected to the gear set 42 and the slider 44. The drive motor 41 drives the gear set 42 to rotate, which in turn drives the cam 43 to rotate. The cam 43 drives the slider 44 to move. When the electric operating device 100 is engaged with the circuit breaker, the slider 44 is connected to the switch handle 2. The slider 44 slides horizontally to drive the switch handle 2 to rotate. In this way, the rotation of the switch handle 2 can be driven by the operation of the drive motor 41.

[0068] Meanwhile, the connecting component 4 can connect the operating panel 3 and the switch handle 2. The operating panel 3 rotates axially and drives the switch handle 2 to move through the connecting component 4 to realize the opening or closing of the circuit breaker. In this embodiment, the operating panel 3 is connected to the gear set 42 and the cam 43, and the drive motor 41 has a clutch function. When there is no power supply, the operating panel 3 can be rotated to drive the gear set 42 to rotate, the cam 43 to rotate, and the slider 44 to move.

[0069] The slider 44 is slidably disposed relative to the slide rail 45. The slide rail 45 extends horizontally, and in this embodiment, there are two slide rails 45 spaced apart.

[0070] When the padlock plate 6 is in the receiving state, the slider 44 can restrict the padlock plate 6 from being hung up in the vertical direction. When the padlock plate 6 is locked, the padlock plate 6 restricts the slider 44 from sliding to restrict the circuit breaker from closing.

[0071] Specifically, the abutment block 65 has a first state and a second state. In this embodiment, the first state and the second state are different angles of rotation relative to the padlock plate 6. When the circuit breaker is closed, the padlock hole 61 is located inside the outer shell 1, that is, in the receiving state, and the abutment block 65 is in the first state. The abutment block 65 abuts against the slider 44 in the vertical direction to restrict the movement of the padlock plate 6 in the vertical direction. When the circuit breaker is open and the padlock plate 6 protrudes out of the outer shell 1 for padlocking, that is, in the padlocking state, the slider 44 moves in the horizontal direction to make way for the abutment block 65. The abutment block 65 is in the second state. The abutment block 65 abuts against the slider 44 in the horizontal direction to restrict the movement of the slider 44 in the horizontal direction.

[0072] The abutment block 65 is provided with a torsion spring 66. When the abutment block 65 rotates from the first state to the second state, the abutment block 65 is driven by the padlock plate 6 to move upward a certain distance, and at the same time the abutment block 65 rotates under the action of the torsion spring 66.

[0073] When the abutment block 65 changes from the second state to the first state, the abutment block 65 is driven by the padlock plate 6 to move downward a certain distance, and the abutment block 65 abuts against the slide rail 45 and rotates relative to the padlock plate 6.

[0074] The lower end of the slider 44 is provided with a relief portion 441 for supporting and limiting the abutment block 65. When the abutment block 65 is in the first state, the abutment block 65 abuts against the relief portion 441 of the slider 44.

[0075] In this embodiment, when the electric operating device 100 is closed, the slider 44 can restrict the padlock plate 6 from being hung up, and when the padlock plate 6 is locked, the abutment block 65 restricts the slider 44 from sliding to prevent the circuit from closing, making it safer to use.

[0076] As shown in Figures 1 to 6, Figures 11 and 14, the padlock baffle 7 is slidably disposed in the horizontal direction. When the padlock plate 6 is locked, the padlock baffle 7 covers the operating hole 112 and the manual operating plate 8. When the circuit breaker is closed, the padlock baffle 7 moves away from the operating hole 112 and the manual operating plate 8 in the horizontal direction.

[0077] In this embodiment, by setting a padlock baffle 7, manual operation by the user is restricted when the padlock plate 6 is in the padlock state, so as to prevent the risk of electric shock.

[0078] When the padlock plate 6 moves vertically, the linkage 9 causes the padlock baffle 7 to slide horizontally.

[0079] The plastic pad 10 is provided with a pivot shaft 130 that pivotally engages with the linkage 9. The linkage 9 is rotatably disposed relative to the pivot shaft 130. In this embodiment, by providing the linkage 9, when the padlock plate 6 moves in the vertical direction, it can drive the padlock baffle 7 to move in the horizontal direction.

[0080] The padlock baffle 7 is provided with a stop hole 71 in the vertical direction. When the circuit breaker is closed, the padlock plate 6 is in the receiving state, and one end of the linkage 9 is inserted into the stop hole 71 in the vertical direction.

[0081] The padlock baffle 7 is provided with a drive plate 72 protruding downward in the vertical direction. When the padlock plate 6 switches from the receiving state to the padlock state, the linkage 9 pushes the drive plate 72 in the horizontal direction to drive the padlock baffle 7 to move in the horizontal direction.

[0082] The padlock baffle 7 is provided with a limiting shaft 73 protruding upward in the vertical direction, the track groove 114 extends in the horizontal direction, the limiting shaft 73 is inserted into the track groove 114 and is slidably disposed relative to the track groove 114.

[0083] The padlock plate 6 is provided with a driving block 67 for abutting against the linkage 9 in the vertical direction. When the padlock plate 6 moves upward, the driving block 67 can drive the linkage 9 to rotate, causing the end of the linkage 9 to disengage from the stop hole 71, and causing the linkage 9 to push the driving plate 72 to move the padlock baffle 7 in the horizontal direction. When the padlock plate 6 moves downward, the upper end of the linkage 9 gradually inserts into the stop hole 71, and drives the padlock baffle 7 to move in the horizontal direction.

[0084] The padlock baffle 7 is located within the exposure slot 81 and abuts against the manual operation plate 8 in the horizontal direction.

[0085] The manual operation panel 8 is provided with a limiting step 83 protruding into the exposure groove 81, and the padlock baffle 7 is installed on the limiting step 83. The limiting step 83 serves to support the padlock baffle 7 on one hand, and to limit the left and right swaying of the padlock baffle 7 on the other hand.

[0086] When the padlock plate 6 is in the retracted state, the user can freely move the manual operation plate 8 without moving the padlock baffle 7. This allows the manual operation plate 8 to be positioned between the operation hole 112 and the operation panel 3, or to position the exposure groove 81 between the operation hole 112 and the operation panel 3. However, when the padlock plate 6 is in the padlocked state, the padlock baffle 7 pushes the manual operation plate 8. Although the exposure groove 81 is located between the operation hole 112 and the operation panel 3, the padlock baffle 7 is necessarily positioned within the exposure groove 81, thus blocking the operation panel 3 and preventing the dangers associated with manual operation.

[0087] By setting the linkage 9, the padlock plate 6 can drive the padlock baffle 7 to move, thus avoiding the danger of manual operation when padlocking.

[0088] The control circuit board 5 is electrically connected to the connection component 4 to control the operation of the connection component 4. More specifically, the control circuit board 5 is provided with a switching power supply, a power conversion circuit, a sampling switch and circuit, and a control circuit.

[0089] The switching power supply is used to control the switching of the drive motor 41, and the power conversion circuit is used to adjust the output voltage. The sampling switch may include manual / automatic status sampling, open / closed position sampling, reset signal sampling, or trip signal sampling, etc. The control circuit can realize functions such as remote control.

[0090] As shown in Figures 1 to 7 and Figures 15 to 16, the display hole 111 is vertically aligned with the operation disk 3. The operation disk 3 has at least two types of first display portions 32 exposed from the display hole 111.

[0091] The split-open indicator slide 101 is disposed between the operation panel 3 and the display cover 11, and the split-open indicator slide 101 is provided with a second display part 1011 and a through hole 1012.

[0092] The driving component 102 is used to drive the split-open indicator slide 101 to slide. The driving component 102 drives the split-open indicator slide 101 to move so that the second display part 1011 or the through hole 1012 is located below the display hole 111. When the through hole 1012 is located below the display hole 111, the first display part 32 is exposed from the display hole 111.

[0093] In this embodiment, the first display part 32 consists of different color blocks arranged on the side of the operation disk 3 facing the display cover 11, and is staggered along the circumferential direction; the second display part 1011 consists of another color block arranged on the split indicator slide plate 101.

[0094] More specifically, the second display unit 1011 is a red block, and the two first display units 32 are a green block and a white block, respectively. The identification icon 115 corresponds to different colors: red for ON, green for OFF, and white for TRIPED. When the circuit is closed, the second display unit 1011 is located below the display hole 111, and the display hole 111 can only expose the red color on the second display unit 1011. When the circuit is open, the display hole 111 exposes the green color on the first display unit 32 through the through hole 1012. In this state, if there is a tripping problem, the operation panel 3 will rotate relative to the first display unit 32, and the display hole 111 will expose the white color.

[0095] The driving assembly 102 includes an indicator push rod 1021 and an indicator rotation member 1022. The indicator push rod 1021 and the indicator rotation member 1022 are both disposed on the side of the split-open indicator slide plate 101 away from the display cover 11. The indicator push rod 1021 slides in a direction perpendicular to the split-open indicator slide plate 101. The indicator rotation member 1022 is driven by the indicator push rod 1021 to drive the split-open indicator slide plate 101 to move in the horizontal direction, thereby making the second display part 1011 or the through hole 1012 located below the display hole 111.

[0096] The indicator rotary element 1022 and the plastic liner 10 are rotatably configured.

[0097] The split / joint indicator slide plate 101 is provided with a drive fastener 1015 protruding toward the indicator rotation member 1022. One end of the indicator rotation member 1022 is inserted into the drive fastener 1015 so that the split / joint indicator slide plate 101 can slide when the indicator rotation member 1022 rotates.

[0098] The padlock plate 6 is provided with a limiting hole 68, and the indicating rotary member 1022 is provided with a limiting protrusion 1024. When the circuit breaker is closed, the limiting protrusion 1024 is inserted into the limiting hole 68 to restrict the padlock plate 6 from being hung up. In this embodiment, in addition to the slider 44, the indicating rotary member 1022, which is linked with the open / close indicating slide plate 101, can also play the role of restricting the padlock plate 6 from being locked.

[0099] The outer casing 1 is provided with a reset block 116 protruding toward the open / close indicator slide 101. Specifically, the reset block 116 is provided on the display cover 11. The open / close indicator slide 101 is provided with a first reset spring 1013. When the circuit breaker is closed, the first reset spring 1013 is compressed. When the circuit breaker is opened, the first reset spring 1013 is reset to drive the open / close indicator slide 101 to slide in the horizontal direction.

[0100] The split / open indicator slide plate 101 has a recessed receiving groove 1014 on the side facing the display cover 11, and the first reset spring 1013 is disposed in the receiving groove 1014.

[0101] The indicator push rod 1021 is provided with a second return spring 1023 for abutting against the plastic pad 10. When the circuit breaker is closed, the second return spring 1023 is compressed. When the circuit breaker is opened, the second return spring 1023 is reset to drive the indicator push rod 1021 to slide in the horizontal direction.

[0102] As shown in Figures 1 to 6, the working process of the electric operating device 100 of this application is as follows: when the electric operating device 100 needs to control the circuit breaker to close, it must ensure that the padlock plate 6 is in the receiving state, and drive the slider 44 to slide by manual or electric means, thereby driving the switch handle 2 to rotate.

[0103] When the circuit is closed, the slider 44 abuts against the abutting block 65. The slider 44 restricts the padlock plate 6 from being hooked up by abutting against the abutting block 65. At the same time, the limiting protrusion 1024 of the indicating rotary member 1022 is also inserted into the limiting hole 68, further restricting the hooklock plate 6 from being hooked up, thus providing double protection. Meanwhile, the second display part 1011 is located below the display hole 111, indicating that the circuit is closed. Regardless of whether the electric operating device 100 is in the open or closed state, as long as the padlock plate 6 is not hooked up, the user can manually move the manual operating plate 8 to decide whether to manually control the operating panel 3.

[0104] When the circuit breaker is open and the padlock plate 6 is not engaged, the slider 44 slides relative to the circuit breaker. At this time, in the vertical direction, the slider 44 makes way for the abutment block 65, and the indicator push rod 1021 moves upward, causing the indicator rotary member 1022 to rotate, which in turn causes the open / close indicator slide plate 101 to slide, so that the through hole 1012 is located below the display hole 111, exposing the first display part 32. At the same time, the limiting protrusion 1024 disengages from the limiting hole 68 and no longer limits the padlock plate 6. In this state, the padlock plate 6 can be engaged.

[0105] When the circuit breaker is tripped and the padlock plate 6 is suspended, the abutment block 65 is raised and rotates relative to it to abut the slider 44 in the horizontal direction to prevent the circuit breaker from closing. At the same time, the drive block 67 moves upward, causing the linkage 9 to rotate and causing the padlock baffle 7 to move above the operation panel 3 to block the keyhole 31, thus preventing manual operation by the user.

[0106] When the padlock is released, the padlock plate 6 returns to the receiving state under the action of the second return spring 1023, while the abutment block 65 returns to the first state under the action of the torsion spring 66, releasing the restriction on the slider 44, and the padlock baffle 7 moves horizontally away from the operating hole 112 and the manual operating plate 8.

[0107] When switching from open to closed, the slider 44 moves above the abutment block 65, and the first reset spring 1013 pushes the open / close indicator slide plate 101 to slide, causing the indicator rotary member 1022 to rotate and causing the limit protrusion 1024 to insert into the limit hole 68.

[0108] The electric operating device 100 of this application, by setting an opening / closing indicator slide plate 101 and a drive assembly 102, realizes the indication of opening, closing, and tripping, and can cooperate with the padlock plate 6 to achieve the effect of limiting the padlock plate 6 when closing. By setting a stop block 65, the slider 44 is restricted from hanging up when closing, and when the padlock plate 6 is hung up, the movement of the slider 44 is restricted to close the circuit, thereby improving safety. By setting a padlock baffle 7, manual operation is restricted when the padlock plate 6 is hung up, further improving safety. The electric operating device 100 of this application can realize electric automatic control as well as manual control, with a compact structure, convenient use, and high safety.

[0109] 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.

[0110] 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 protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
