Description

Technical Field

[0001] The present invention relates to the field of ink cartridge regeneration, and in particular to a jig and an ink cartridge regeneration method. Background Art

[0002] A type of existing small-capacity recycled ink cartridge product utilizes a single through-hole structure on the bottom shell of the used original ink cartridge for refilling. Each through-hole directly connects to only one chamber within the cartridge, and multiple chambers within the cartridge are connected by channels. The standard refill volume of the recycled ink cartridge is greater than the capacity of any of these chambers. Ink can only enter other chambers through the channels under the influence of negative pressure within the cartridge. However, the channels connecting certain chambers within the cartridge are narrow and elongated, resulting in prolonged refilling and affecting efficiency. Furthermore, if the original ink cartridge is not properly cleaned, ink sediment or other foreign matter may clog the channels, preventing sufficient ink refill. Summary of the Invention

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0039] Figure 1 This is a schematic diagram of the structure of recycled original ink cartridges (recycled ink cartridges). Original ink cartridges are usually ink cartridges used by end users that are recycled from the market. Original ink cartridges can be remanufactured to obtain recycled ink cartridges.

[0040] like Figures 1 to 4 As shown, the original ink cartridge is surrounded by a bottom shell 1 and a surface cover 2 to form a roughly rectangular box-shaped structure. The bottom shell 1 has a top wall 11, a bottom wall 12, a front wall 13, a rear wall 14 and a main side wall 15. The top wall 11 and the bottom wall 12 are relatively arranged in the height direction of the original ink cartridge, the front wall 13 and the rear wall 14 are relatively arranged in the length direction of the original ink cartridge, and the main side wall 15 and the surface cover 2 are relatively arranged in the width direction of the original ink cartridge. The direction from the surface cover 2 to the main side wall 15 is a first direction, and the direction from the main side wall 15 to the surface cover 2 is the opposite direction of the first direction. The first direction is parallel to the width direction of the original ink cartridge.

[0041] In order to better illustrate the various components of the ink cartridge, a three-dimensional rectangular coordinate system XYZ axis is established. When the original ink cartridge is in use (installed in the installation cavity in an upright posture), the vertical direction (gravity direction) is set as the Z axis direction, the direction from the top wall 11 to the bottom wall 12 is the -Z direction (gravity direction), and the Z axis direction is also the height direction of the original ink cartridge. The horizontal direction is the X direction, and the direction from the rear wall 14 to the front wall 13 is the +X direction. The X direction is also the length direction of the original ink cartridge, the width direction of the original ink cartridge is the Y direction, and the direction of the face cover 2 pointing to the main side wall 15 is the +Y direction, that is, the first direction.

[0042] like Figure 4 As shown, the original ink cartridge includes a second section for storing ink, an ink outlet 3, a liquid channel, an air inlet 401, and a gas channel. The second section is the space on the side opposite the main side wall 15 in the first direction of the bottom shell 1. The second section includes a first ink storage chamber 16 and a second ink storage chamber 17. Specifically, the first and second ink storage chambers 16, 17 are disposed within the bottom shell 1 and are located on the opposite side of the main side wall 15 in the first direction (the -Y direction side). The first and second ink storage chambers 16, 17 are interconnected.

[0043] like Figures 1 to 4 As shown, the ink outlet 3 is provided on the bottom wall 12 of the bottom shell 1 and protrudes downward (protrudes along the -Z direction). The ink outlet 3 is used to supply the ink in the first ink storage chamber 16 and the second ink storage chamber 17 to the outside of the original ink cartridge (supplied to the printer).

[0044] like Figure 2 and Figure 3As shown, a liquid channel is provided on the bottom housing 1. The liquid channel connects the first and second ink storage chambers 16 and 17 with the ink outlet 3, allowing ink in the first and second ink storage chambers 16 and 17 to flow to the ink outlet 3. A differential pressure valve 5 is provided in the liquid channel. The differential pressure valve 5 comprises a rubber diaphragm 51, a spring 52, and a valve cover 53. The differential pressure valve 5 opens the liquid channel when the pressure in the flow path between the differential pressure valve and the ink outlet 3 (i.e., the downstream pressure) is lower than the pressure in the flow path between the differential pressure valve and the first and second ink storage chambers 16 and 17 (i.e., the upstream pressure), and when the difference between the downstream and upstream pressures exceeds a predetermined value. The differential pressure valve closes the liquid channel when the difference between the downstream and upstream pressures is less than the predetermined value, or when the downstream pressure exceeds the upstream pressure. This structure ensures that ink is properly supplied from the first and second ink storage chambers 16 and 17 to the ink outlet 3 and prevents reverse flow of ink.

[0045] like Figures 2 to 4 As shown, the air inlet 401 is provided on the main side wall 15 of the bottom shell 1 and passes through the main side wall 15 . The air inlet 401 is located at a position of the main side wall 15 close to the top wall 11 and the rear wall 14 .

[0046] like Figure 3 and Figure 4 As shown, a gas channel is provided on the bottom shell 1, connecting the air inlet 401 with the first ink storage chamber 16 and the second ink storage chamber 17. When the original ink cartridge is in use, air enters the bottom shell 1 through the air inlet 401 and flows through the gas channel to the first ink storage chamber 16 and the second ink storage chamber 17, allowing the original ink cartridge to supply ink normally. The bottom shell 1 is provided with a plurality of flow holes, which extend through the main side wall 15. The plurality of flow holes include a first flow hole 402, a second flow hole 405, a third flow hole 406, a fourth flow hole 407, a fifth flow hole 415, and a sixth flow hole 416. These flow holes constitute part of the gas channel. Air entering from the air inlet 401 flows through the first flow hole 402, the second flow hole 405, the third flow hole 406, the fourth flow hole 407, the fifth flow hole 415, and the sixth flow hole 416 in sequence and enters the first ink storage chamber 16.

[0047] like Figure 3 and Figure 4 As shown, the gas channel includes a curved flow path portion 403 , a barrier flow path portion, a first chamber 18 , a capture portion and a second chamber 19 , which are sequentially arranged in a direction from the air inlet 401 toward the first ink storage chamber 16 .

[0048] like Figure 4As shown, the first chamber 18 and the second chamber 19 are arranged on the opposite side of the main side wall 15 of the bottom shell 1 in the first direction (-Y direction side), and the first chamber 18 and the second chamber 19 are also part of the second section. The first chamber 18 and the second chamber 19 can accommodate ink and can also accommodate air trapped in the middle of entering the gas channel. The first chamber 18 and the second chamber 19 are connected to the first ink storage chamber 16 and the second ink storage chamber 17.

[0049] like Figure 3 and Figure 4 As shown, the two ends of the curved flow path portion 403 are connected to the first flow hole 402 and the second flow hole 405 respectively, and the first flow hole 402 is connected to the air inlet 401. The curved flow path portion 406 has multiple winding flow paths with small cross-sectional areas and long paths, which can reduce the amount of volatile components of the ink in the original ink cartridge that evaporate through the gas flow path.

[0050] like Figure 2 As shown, the gas passage is sealed by a breathable membrane 6 at a location closer to the air inlet 401 than the capture portion. The breathable membrane 6 is welded to the first direction side (+Y direction side) of the peripheral wall 151 surrounding the second flow hole 405. The peripheral wall 151 protrudes from the main side wall 15 along the first direction. The breathable membrane 6 is air-permeable but liquid-impermeable. That is, air can flow through the breathable membrane 6, but ink in the original ink cartridge cannot flow through the breathable membrane 6, thus preventing the ink from flowing out of the ink cartridge.

[0051] The barrier flow path portion is located between the capturing portion and the air-permeable membrane 6 on the gas passage. The barrier flow path portion is a first flow path portion 404 between the second flow hole 405 and the third flow hole 406 and a second flow path portion 408 between the third flow hole 406 and the fourth flow hole 407 .

[0052] like Figure 3 and Figure 4 As shown, the fourth flow hole 407 is located in the first chamber 18, the capture portion connects the first chamber 18 and the second chamber 19, the fifth flow hole 415 is located in the second chamber 19, and the sixth flow hole 416 is located in the first ink storage chamber 16. The fifth flow hole 415 and the sixth flow hole 416 are connected through the third flow path portion 409 on the main side wall 15.

[0053] like Figures 2 to 4 As shown, air enters from the air inlet 401 and passes through the first flow hole 402, the curved flow path portion 403, the second flow hole 405, the first flow path portion 404, the third flow hole 406, the second flow path portion 408, the fourth flow hole 407, the first chamber 18, the capture portion, the second chamber 19, the fifth flow hole 415, the third flow path portion 409, and the sixth flow hole 416 into the first ink storage chamber 16.

[0054] like Figures 2 to 4As shown, the capture portion has the function of capturing ink that intrudes into the gas channel. The capture portion includes a first section 412, a first channel 410, and a second channel 411. These sections 412, 410, and 411 all function to capture ink, thereby reducing the possibility of ink within the first and second ink storage chambers 16, 17 escaping through the gas inlet 401. The main sidewall 15 is provided with a peripheral wall 152 protruding from the first direction side (+Y direction side). The peripheral wall 152 and the main sidewall 15 enclose the first section 412. A first channel 410 extends through the main sidewall 15, connecting the first section 412 with the first chamber 18. A second channel 411 extends through the main sidewall 15, connecting the first section 412 with the second chamber 19. The openings of the first and second channels 410, 411 on the +Y axis side are enclosed within the peripheral wall 152, thereby connecting the first section 412 with the first and second channels 410, 411.

[0055] like Figure 1 and Figure 2 As shown, the original ink cartridge also includes a partition film 7, which is welded to the first direction side (+Y direction side) of the outer wall 152. The partition film 7 separates the first interval 412 from the outside world. The range of the first interval 412 is jointly limited by the partition film 7, the outer wall 152 and the main side wall 15.

[0056] Observed in the opposite direction of the first direction (-Y direction), the first section 412 is roughly strip-shaped, preferably waist-shaped, and the first channel 410 and the second channel 411 are arranged along the length direction of the first section 412. The aspect ratio of the first section 412 is 2:1 to 4:1. The smaller aspect ratio of the first section 412 is conducive to forming a closed transfer section 240 with the injection part 210 of the jig during ink injection (detailed description will be given later).

[0057] In addition to being welded to the outer wall 152 to enclose the first section 412, the partition film 7 is also welded to the entire first-direction side of the main side wall 15, isolating all flow paths and flow holes on the first-direction side of the main side wall 15 from the outside world. The air inlet 401 does not require the partition film 7. Instead, a sealing film 71 is provided at the air inlet 401 to seal it. This sealing film 71 is removed when the ink cartridge is installed in the printer for use.

[0058] like Figure 1As shown, the original ink cartridge also includes a chip 8 and a handle 9. Both are mounted on the front wall 13 of the bottom shell 1, with the chip 8 positioned near the lower end of the front wall 13 and the handle 9 positioned above the chip 8. Chip 8 stores information about the ink cartridge. When the original ink cartridge is installed in the printer, the terminals of chip 8 contact and electrically connect with the printer's contact pins, enabling the printer to read the cartridge information. The handle 9 is swingably connected to the front wall 13 and includes a structure for engaging with the printer to secure the original ink cartridge in place. To remove the ink cartridge, the handle 9 is swung to release its engagement with the printer.

[0059] like Figure 5 As shown, this embodiment discloses a jig for regenerating an original ink cartridge. The jig includes an injection component 210 , a blocking component 220 and a suction component 230 .

[0060] like Figures 3 to 7 As shown, the injection piece 210 and the original ink cartridge are enclosed on the first direction side (+Y direction side) of the main side wall 15 to form a transfer interval 240, and the transfer interval 240 includes at least part of the first interval 412, and the transfer interval 240 is connected with the first channel 410 and the second channel 411, that is, the transfer interval 240 includes at least the part in the first interval 412 that is connected with the first channel 410 and the second channel 411, so that the injection piece 210 can pass through the transfer interval 240 (first interval 412) through the first channel 410 and the second channel 411 to inject ink into the first chamber 18 and the second chamber 19 at the same time.

[0061] like Figure 6 As shown, the injection member 210 includes a main body 211 and an elastic sealing portion 212. The main body 211 is located on the first direction side (+Y direction side) of the sealing portion 212. The injection member 210 has an input channel 213 that communicates with the transfer zone 240. The input channel 213 runs through the main body 211 and the sealing portion 212. The input channel 213 can be directly or indirectly connected to an external ink storage device (such as an ink tank, etc.). At least a portion of the sealing portion 212 and the original ink cartridge are enclosed on the first direction side of the main side wall 15 to form the transfer zone 240. When injecting ink, it is necessary to open a hole in the partition membrane 7 at a position corresponding to the first zone 412 so that the injection member 210 can inject ink into the first zone 412. Since the hole is opened in the partition membrane 7, its sealing performance is destroyed. To prevent ink from flowing out during ink injection, the sealing portion 212 is provided to cooperate with the original ink cartridge to form the transfer zone 240 and re-separate the transfer zone 240 from the outside world. The sealing portion 212 may be made of rubber.

[0062] The sealing portion 212 of the injection member 210 can be engaged with the first direction side of the partition film 7 to form the transfer area 240; in some original ink cartridges where the partition film 7 has been removed, the sealing portion 212 can also be engaged with the first direction side of the main side wall 15.

[0063] Further, such as Figure 5 As shown, when viewed in the opposite direction of the first direction, the extension range of the outer wall 152 coincides with the extension range of the sealing portion 212, that is, the end face of the sealing portion 212 in the -Y direction abuts against the end face of the first direction side of the outer wall 152 (or the partition wall film 7 attached to the outer wall 152) to form a transfer interval 240. At this time, the transfer interval 240 includes the entire first interval 412.

[0064] Optionally, when viewed in the opposite direction to the first direction, the extension range of the outer wall 152 is within the extension range of the sealing portion 212, and the sealing portion 212 of the injection member 210 can be covered on the outside of the outer wall 152, that is, the sealing portion 212 abuts against the first direction side of the partition wall membrane 7 or the main side wall 15 outside the range of the outer wall 152 to form a transfer interval 240. At this time, the transfer interval 240 also includes the entire first interval 412.

[0065] Optionally, when viewed in the opposite direction to the first direction, the extension range of the outer wall 152 is outside the extension range of the sealing portion 212, that is, the sealing portion 212 of the injection piece 210 can be inserted into the first interval 412, that is, the sealing portion 212 is located on the inner side of the outer wall 152, and the sealing portion 212 can abut against the main side wall 15 in the outer wall 152 to form a transfer interval 240. At this time, the transfer interval 240 only includes a part of the first interval 412.

[0066] like Figure 5 As shown, the blocking member 220 is used to block the gas channel so that the outside air cannot enter the original ink cartridge during the ink filling process. The blocking member 220 has an elastic blocking portion, which is used to be inserted into the flow hole of the gas channel, thereby blocking the gas flow upstream and downstream of the flow hole, thereby achieving the effect of blocking the gas channel. The blocking member 220 can block any flow hole on the gas channel that is closer to the air inlet 401 than the capture portion (for example, the second flow hole 405, the fourth flow hole 407, these flow holes are closer to the air inlet 401 than the capture portion on the gas channel, and can also directly block the air inlet 401). Specifically, as shown in the figure, the blocking member 220 is inserted into the fourth flow hole 407 to block the gas channel. Before the blocking member 220 blocks the flow hole, it is also necessary to open a hole at the position of the corresponding flow hole on the partition membrane 7 for the blocking member 220 to pass through.

[0067] The partition wall membrane 7 can be opened by using a special hole-opening tool and then inserting / joining the blocking piece 220 or the injection piece 210, or by providing a sharp object on the blocking piece 220 or the injection piece 210 to directly pierce the partition wall membrane 7 and then inserting / joining it.

[0068] like Figure 5 As shown, the suction member 230 cooperates with the original ink cartridge at the ink outlet 3 to suction the interior of the original ink cartridge, creating a negative pressure inside the original ink cartridge. The suction member 230 is connected to the ink outlet 3 and to an external suction device (such as a vacuum pump, etc.), thereby being able to suck air and / or residual ink (fluid) from the original ink cartridge. Before suction, the air passage is blocked by the blocking member 220 to prevent external air from entering the original ink cartridge. After suction is performed by the suction member 230, the air and / or ink in the original ink cartridge are removed, forming a negative pressure state (internal air pressure is lower than atmospheric pressure, or can also be a vacuum state) inside the original ink cartridge.

[0069] like Figure 5 As shown, this embodiment also discloses an ink cartridge regeneration method, which uses the above-mentioned jig to regenerate the original ink cartridge, thereby obtaining a reusable regenerated ink cartridge.

[0070] The ink cartridge regeneration method of this embodiment includes the following steps:

[0071] S1: Use the blocking member 220 to block the gas passage on the bottom shell 1;

[0072] S2: Using the suction member 230 to suck the original ink cartridge to generate negative pressure in the original ink cartridge;

[0073] S3: Engage the injection member 210 with the first direction side of the main side wall 15 so that the injection member 210 and the original ink cartridge are surrounded on the first direction side of the main side wall 15 to form a transfer section 240. The transfer section 240 includes at least a portion of the first section 412, and the transfer section 240 is connected to the first channel 410 and the second channel 411.

[0074] Ink is injected into the transfer zone 240 through the injection member 210 . The ink in the transfer zone 240 flows into the first chamber 18 and the second chamber 19 from the first channel 410 and the second channel 411 under the action of negative pressure.

[0075] Specifically, in step S1 , the blocking member 220 may be joined to at least one flow hole of the gas channel to block the gas channel to prevent outside air from entering. Preferably, the blocking member 220 only blocks one flow hole (eg, the fourth flow hole 407 ).

[0076] Before using the blocking piece 220 for blocking, a step of drilling holes in the partition wall membrane 7 is also included. Holes are drilled at positions on the partition wall membrane 7 corresponding to the flow holes that need to be blocked, so that the blocking piece 220 can pass through the partition wall membrane 7 and be inserted into the flow holes.

[0077] Specifically, in step S2: the suction piece 230 is connected to the ink outlet 3 of the original ink cartridge, and then the ink outlet 3 is used to suction the inside of the original ink cartridge to suck away the air and / or residual ink (fluid) in the original ink cartridge. Before suction, the gas channel is blocked by the sealing piece 220, so that the outside air cannot enter the original ink cartridge, and a negative pressure state is formed in the original ink cartridge, that is, the pressure of the original ink cartridge is lower than the external air pressure. In this way, the ink can flow into the original ink cartridge efficiently when filling the ink.

[0078] Specifically, in step S3, the injection member 210 can be joined to the original ink cartridge in a number of ways as described above. For example, the sealing portion 212 of the injection member 210 can be joined to the peripheral wall 152 or to a position on the partition film 7 corresponding to the peripheral wall 152; or, the sealing portion 212 of the injection member 210 can be joined to the partition film 7 or the main side wall 15 outside the peripheral wall 152; or, the sealing portion 212 of the injection member 210 can be joined to the main side wall 15 inside the peripheral wall 152. Different sizes of injection members 210 can be joined in different ways, as long as they can form a transfer section 240 with the original ink cartridge on the first direction side (+Y direction side) of the main side wall 15, and the transfer section 240 includes at least a portion of the first section 412.

[0079] Before joining the injection member 210 , a step of drilling a hole in the partition wall membrane 7 is also included. A hole needs to be drilled at a position corresponding to the first interval 412 on the partition wall membrane 7 so that the injection member 210 can inject ink into the first interval 412 / transfer interval 240 .

[0080] After the injection member 210 is connected to the original ink cartridge, the ink is injected into the transfer zone 240 (injected through the input channel 213) through the injection member 210. The ink in the transfer zone 240 enters the first chamber 18 and the second chamber 19 from the first channel 410 and the second channel 411 under the action of negative pressure. During the ink injection process, the suction member 230 can be in a continuous suction state, so that the pressure differential valve 5 of the original ink cartridge can remain open, and the interior of the original ink cartridge can be maintained in a stable negative pressure state, which has a high ink injection efficiency. Alternatively, the suction member 230 can be removed from the original ink cartridge, and the pressure differential valve 5 of the original ink cartridge automatically closes under the action of the pressure differential and maintains the interior of the original ink cartridge at the initial negative pressure state that meets the process requirements. During the ink injection process, in both cases, the blocking member 220 must remain in a state of blocking the gas channel to ensure that the ink can enter the first chamber 18 and the second chamber 19 under the action of negative pressure, and then continue to flow to the first ink storage chamber 16 and the second ink storage chamber 17.

[0081] After the original ink cartridge is filled with a sufficient amount of ink, the suction member 230 can be stopped from suctioning, and the suction member 230, injection member 210, and blocking member 220 can be removed from the original ink cartridge. Then, the openings in the partition film 7 (including the holes through which the blocking member 220 and injection member 210 pass) can be sealed. In this step, the original partition film 7 with the openings can be completely removed and a new, complete partition film 7 can be welded to the first direction side of the main side wall 15 to seal the openings. Alternatively, the openings can be sealed by welding a small partition film 7 to cover the openings, with each opening covered with a small partition film 7 to seal the openings.

[0082] After that, it is necessary to weld a new sealing film 71 at the air inlet 401 and a new sealing film at the ink outlet 3. If there is any residue of the sealing film that was originally punctured at the ink outlet 3, it is necessary to remove the remaining old sealing film before welding the new sealing film. At this point, the regeneration of the original ink cartridge is completed, and a reusable regenerated ink cartridge is obtained.

[0083] When the jig of the present invention is used to regenerate the original ink cartridge, the injection member 210 can utilize the transfer section 240 (including at least part of the first section 412) to simultaneously inject ink into the first chamber 18 and the second chamber 19, thereby improving the ink injection efficiency. In addition, the first channel 410 and the second channel 411 are relatively short in length and have a large cross-sectional area among the multiple channel structures of the bottom shell 1 (for example, they can be compared with the curved flow path portion 403), and are less prone to clogging, which helps to ensure sufficient filling of ink.

[0084] It should be noted that the original ink cartridge is provided with a plurality of mutually connected capture parts. When using a jig to fill ink through the transfer section 240, a plurality of mutually connected capture parts are required. The first capture part A and the second capture part B are used as an example for explanation. The bottom shell 1 is provided with a first through hole 413, a second through hole 414, a third through hole 417 and a fourth through hole 418 that penetrate the main side wall 15 along the first direction. The first through hole 413 and the second through hole 414 are arranged at intervals in the height direction, and the first through hole 413 and the second through hole 414 are surrounded by an outer wall 152 and form a first interval 412a on the inner side of the outer wall 152. The first through hole 413, the second through hole 414 and the first interval 412a belong to the first capture part A; the third through hole 417 and the fourth through hole 418 are arranged at intervals in the height direction, and the third through hole 417 and the fourth through hole 418 are surrounded by another outer wall 152 and form another first interval 412b on the inner side of the outer wall 152. The third through hole 417, the fourth through hole 418 and the first interval 412b belong to the second capture part B. The first through hole 413 and the fourth through hole 418 are connected via the fourth flow path portion 419 , so that the first capturing portion A and the second capturing portion B are connected to each other.

[0085] In some embodiments, as Figures 3 to 5 As shown, when the injection member 210 is joined to the first capture portion A to form a transfer interval 240 (the transfer interval 240 includes at least a portion of the first interval 412a), the first through hole 413, the fourth flow path portion 419, the fourth through hole 418, the first interval 412b and the third through hole 417 together constitute a first channel 410 to connect the first chamber 18, and the second through hole 414 serves as a second channel 411 to connect the second chamber 19.

[0086] Optional, such as Figure 3 and Figure 7 As shown, when the injection member 210 is engaged with the second capture portion B to form the transfer section 240 (the transfer section 240 includes at least a portion of the first section 412b), the third through hole 417 serves as the first channel 410 to communicate with the first chamber 18. The fourth through hole 418, the fourth flow path portion 419, the first through hole 413, the first section 412a, and the second through hole 414 collectively form the second channel 411 to communicate with the second chamber 19. Any capture portion on the original ink cartridge can be used to engage the injection member 210 for ink injection.

[0087] It should be noted that if Figure 3 As shown, the structure formed by the third flow hole 406, the fourth flow hole 407, and the second flow path portion 408 connecting the two on the original ink cartridge is similar to the capture portion, and theoretically, ink can also be injected through the injection piece 210. However, this is not a preferred location because the distance between the third flow hole 406 and the fourth flow hole 407 is large, resulting in a longer length of the second flow path portion 408 (which can be regarded as the first section 412). In other words, the aspect ratio of the first section 412 is large, making it difficult for the injection piece 210 to interact with it to form a closed transfer section 240, which is prone to leakage during ink injection. Therefore, when selecting a capture portion for engaging the injection piece 210, it is necessary to select a first section 412 with a smaller aspect ratio (such as an aspect ratio of 2:1) to facilitate the formation of a closed transfer section 240 with the injection piece 210.

[0088] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
