Description

Technical Field

[0001] The invention belongs to the technical field of 3D printing of recycled plastics, and in particular relates to a device for processing precision plastic parts made of recycled materials. Background Art

[0002] Recycled plastics, also known as recycled plastics, are plastic products that have been used or discarded and converted back into usable plastic raw materials. There is a huge demand gap. Recycled plastics include PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene copolymer), etc. Among them, ABS plastic products have the characteristics of impact resistance, heat resistance, low temperature resistance, good chemical corrosion resistance, and high surface gloss, and are widely used.

[0003] In the preparation of precision plastic parts, recycled plastics have won the favor of many manufacturers for their strong properties, especially through 3D printing additive manufacturing technology, which does not require the production of blanks or intermediates, eliminating many process steps. However, in this additive manufacturing process, there are still areas that need to be improved: 1. 3D printing recycled plastics will produce toxic gases during the melting process, which can be inhaled by the human body and cause great harm to the respiratory organs.

[0004] 2. Using a fan to blow air to carry away toxic gases is inconvenient to limit the airflow to get rid of the printing point, which may cause the print to be distorted and cause partial deviations in the print. Summary of the invention

[0005] The purpose of the present invention is to provide a device for processing precision plastic parts made of recycled materials, which can remove toxic gases while dissipating heat for printed parts, and the adsorbent colloid can absorb harmful gases and expand to further seal them, thereby stably limiting the airflow to make way for printing points.

[0006] The technical solution adopted by the present invention is as follows: A device for processing recycled material precision plastic parts, comprising: A chassis, wherein a print head, a three-dimensional displacement system for moving the print head, and an air intake mechanism staggered with the print head are arranged inside the chassis; A loading platform, the loading platform is connected to the three-dimensional displacement system, an air storage tank connected to the air intake mechanism is provided inside the loading platform, and micropores connected to the air storage tank are provided on the surface of the loading platform, a plug and a lining member and a pulling member connected to the plug are provided inside the micropore, and an end of the plug passing through the micropore is provided with a ring-shaped adsorbent colloid and an air outlet connected to the air storage tank at intervals; A consumable part, wherein the consumable part is used to be laid on the material loading platform to cushion the bottom of the printed part, and a magnetic material for attracting the liner member is embedded in the consumable part; During printing, the consumable part presses down part of the plug to close the micropores and the air outlet to limit the airflow from avoiding the printing point and dissipate heat for the printed part, and clean up the toxic gas, so that the other part of the plug can position the consumable part.

[0007] As an optional solution, the outside of the plug is bonded with a fluororubber ring for coating the adsorbent colloid and a positive flange bonded to the outside of the fluororubber ring, the fluororubber ring is provided with air holes for the adsorbent colloid to contact toxic gases, and the outer edge of the micropore is fixed with a reverse flange that matches the positive flange, and the positive flange and the reverse flange are used to block slag when they are engaged.

[0008] As an optional solution, the lining kit includes an inner magnet fixed in sequence inside the air storage tank along the axial direction of the micropore, a clamping member for supporting the inner magnet, a first elastic member bonded to the outer side of the clamping member, and an alloy skeleton; an outer magnet for attracting the inner magnet and the magnetic material is embedded in one end of the plug away from the loading platform, and an inner bent pin fit with the clamping member is fixed on the other end.

[0009] As an optional solution, the pulling member includes a second elastic member bonded to one end of the inner bent pin close to the alloy frame, and the four corners of the alloy frame are embedded with limiting columns fixedly connected to the inner wall of the gas storage tank.

[0010] As an optional solution, a seat bracket transmission-connected to the three-dimensional displacement system and two hollow frames distributed at both ends of the seat bracket are fixed to a side of the loading platform away from the plug.

[0011] As an optional solution, the air intake mechanism includes an air intake pipe, a connecting pipe and a one-way valve which are sequentially connected to the air storage tank, and the one-way valve is used to limit the air flow toward the inside of the chassis.

[0012] As an optional solution, the air inlet of the one-way valve is connected to an air tank and an air pump in sequence, and the one-way valve is pushed open when the internal pressure of the air tank reaches a set value.

[0013] As an optional solution, a silo and a guide wheel tube are fixed to the back of the chassis, and a winding roller for winding the recycled material is rotatably installed in the middle of the silo.

[0014] As an optional solution, a cooling fan and a slide rail connected to the three-dimensional displacement system are installed at intervals on the print head; Wherein, the blowing direction of the cooling fan is staggered from the loading platform.

[0015] As an optional solution, an air collecting hood facing the loading platform and a bellows connected to the air collecting hood are fixed on the top of the chassis, and an exhaust fan for attracting air flow inside the chassis is fixed to the air inlet of the air collecting hood.

[0016] The technical effects achieved by the present invention are: The present invention processes recycled materials through 3D printing technology, uses disposable consumables as a base to pad the printed part, and presses the micropores below, so that the air outlet on the other part of the plug blows airflow toward the inside and outside of the printed part, taking away the toxic gas while dissipating the heat for the printed part, and the adsorbent colloid can absorb harmful gases and expand, further closing the micropores, avoiding air leakage to blow to the printing point, and stably limiting the airflow to keep away from the printing point. This action can follow the rise and fall of the loading platform without interference, thereby promoting a smooth printing process. The staff can wait for the printing to be completed in a safe position, and the consumables can be smashed to demold after printing is completed.

[0017] Once the plug is inserted into the micropore, the reverse flange and the air outlet are driven to sink into the micropore, so that the reverse flange passes over the positive flange and then rebounds, and then engages with the positive flange to limit the plug. The plug can be limited and will not be pushed out of the micropore when exposed to wind. During this process, the air pores are continuously open, which is convenient for the adsorbent colloid to absorb harmful gases and expand. At the same time, the reverse flange is pushed to adhere to the wall in the micropore, making the closure tighter. While preventing air leakage, it can also block the slag dropped from the printed part, thereby realizing the function of preventing slag blockage.

[0018] The present invention uses an inner magnet to attract an outer magnet in a micropore, so that the plug can be inserted into a clamp. The clamp supports the inner magnet and engages with the clamp through its upper and lower bends, so that the plug can be inserted into the micropore. At the same time, the magnetic material in the consumable part is sucked tightly to realize vertical positioning of the consumable part, and the consumable part is positioned horizontally with the remaining part of the plug, so that the consumable part can be kept stable. After printing is completed, the consumable part is lifted, and the plug is pulled up by magnetic attraction to automatically detach from the micropore, and then the printed part is broken to remove the magnetic material for recycling.

[0019] The present invention changes the way the micropores send airflow toward the inside of the chassis, so that the airflow is sucked into the micropores and harmful gases are taken away. All micropores maintain smooth airflow and generate a certain suction force to absorb the consumables. The adsorbent colloid, fluororubber ring, positive flange, and reverse flange on the plug are also removed, and the plug is pressed into the micropore. This saves the steps of disassembling and assembling the adsorbent colloid and simplifies the printing steps. The magnetic material and the magnetic attraction between the inner magnet and the outer magnet are used to vertically position the consumables. In addition, the remaining part of the plug can horizontally position the consumables, which also enables the consumables to stably carry the printed parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0023] Recycled plastic, also known as recycled plastic, is not a specific plastic material, but refers to the process of converting used or discarded plastic products into usable plastic raw materials through a specific recycling process. In this process, discarded plastic products such as plastic bags, plastic bottles, plastic containers, etc. are collected, and after steps such as cleaning, melting, and granulation, they are finally made into recycled plastic particles and plastic wires, collectively referred to as recycled materials. These recycled materials can be processed into various plastic products again, thereby realizing the recycling of plastics. For example, they can be processed into precision plastic parts through 3D printers, which can take advantage of the high hardness of recycled materials.

[0024] Embodiment 1: like Figure 1-Figure 11 As shown, a device for processing precision plastic parts made of recycled materials includes a chassis, a loading platform 2, and consumables 3. The consumables 3 of a preset shape are used to be laid on the loading platform 2 to cushion the bottom of the printed part. A print head 1, a three-dimensional displacement system for moving the print head 1, and an air intake mechanism staggered with the print head 1 are arranged inside the chassis. The recycled material is first made into a linear winding for standby use, and one end is introduced into the print head 1. The print head 1 is moved on the X-axis and Z-axis by the three-dimensional displacement system, and the loading platform 2 is raised and lowered on the Y-axis. The upper surface of the consumable 3 is used as a reference plane to open a spraying point for the recycled material, and the laser beam is used to melt and form the material quickly. In this process, the air intake mechanism is started to blow airflow, and the consumable 3 limits the airflow blown to the loading platform 2, so that the airflow leaves the printing point, so as to achieve the blowing of toxic gases inside and outside the printed part.

[0025] As an optional embodiment, the consumable part 3 is formed quickly by reverse molding with gypsum as the base material, and the upper and lower surfaces are flattened to support the printed part with a good plane, and can withstand the high temperature environment during printing. In particular, after printing is completed, the consumable part 3 can be broken to quickly complete the demoulding of the printed part, and only gypsum is consumed, which is relatively low in cost.

[0026] In the three-dimensional displacement system, the X-axis and the Z-axis can use electric wheels to drive belts to realize the movement of the print head 1, and the Y-axis can use a motor to rotate a screw to drive the loading platform 2 to rise and fall, so that the print head 1 and the loading platform 2 are isolated and do not interfere with each other.

[0027] See attached Figure 6 , Figure 7 and Fig. 9When the loading platform 2 is connected to the three-dimensional displacement system, the loading platform 2 is moved to the initial position to prepare for loading. In this embodiment, an air storage tank 205 connected to the air inlet mechanism is opened inside the loading platform 2, and micropores 201 connected to the air storage tank 205 are opened on its surface for circulating air. The plug 202 inserted in the micropore 201 is pressed down by the consumable part 3 to block the micropore 201 directly below the print. At one end of the plug 202 passing through the micropore 201, a ring-shaped adsorbent colloid 203 and an air outlet 204 connected to the air storage tank 205 are arranged at intervals. Part of the plug 20 2 drives the adsorbent colloid 203 and the air outlet 204 into the micropore 201, and the remaining adsorbent colloid 203 and the air outlet 204 are exposed to the outside. In this way, the air intake mechanism is started to blow air during the printing process. When the air is inhaled, the air flow enters the air storage tank 205 and is distributed to the opened micropore 201, so that the remaining part of the air outlet 204 blows the air flow, and the air flow is vertically distributed to the inside and outside of the print, taking away the toxic gas while dissipating the heat for the print, and the adsorbent colloid 203 can absorb the harmful gas and expand, further closing the micropore 201, avoiding air leakage from blowing to the printing point, and realizing stable restriction of the air flow to let the printing point go.

[0028] As an optional embodiment, the adsorbent colloid 203 may be made of DMSO (dimethyl sulfoxide), which can absorb components such as acrylonitrile, styrene, butadiene, etc. in harmful gases and expand to a certain extent.

[0029] See attached Figure 4 and Figure 5 Since the loading platform 2 is hollowed out by the gas storage tank 205, it needs to be reinforced. Therefore, in this embodiment, a seat bracket 7 that is transmission-connected to the three-dimensional displacement system and two hollow frames 8 distributed at both ends of the seat bracket 7 are fixed by screws on the side of the loading platform 2 away from the plug 202. The seat bracket 7 and the hollow frames 8 improve the structural strength of the loading platform 2, and strengthen the connection with the three-dimensional displacement system, so as to facilitate the loading of heavier printed parts.

[0030] See attached Figure 7 , Fig. 9 and Fig.10During the pressing process, the adsorbent colloid 203 is soft and easy to be scraped off, and needs to be reinforced. Therefore, a fluororubber ring 4 for coating the adsorbent colloid 203 and a positive flange 402 bonded to the outside of the fluororubber ring 4 are sleeved on the outside of the plug 202. At this node, the fluororubber ring 4 does not react with the adsorbent colloid 203 and can limit the position well. A vent hole 401 is provided on the fluororubber ring 4 for the adsorbent colloid 203 to contact the toxic gas, which is convenient for absorbing the toxic gas. The outer edge of the micropore 201 is welded with a flange 402 that matches the positive flange 402. The reverse flange 403, once the plug 202 is inserted into the micropore 201, drives the reverse flange 403 and the air outlet 204 to sink into the micropore 201, so that the reverse flange 403 goes over the positive flange 402 and then rebounds, and then engages with the positive flange 402 to limit the plug 202, so that the plug 202 can be limited and will not be pushed out of the micropore 201 when exposed to wind. In this process, the air pore 401 is continuously open, which is convenient for the adsorbent colloid 203 to absorb harmful gases and expand. At the same time, the reverse flange 403 is pushed to adhere to the wall in the micropore 201, and the closure is tighter, which is conducive to preventing air leakage.

[0031] When the recycled material is melted, it has a certain fluidity and may partially drip to produce slag. This embodiment blocks the slag when the positive flange 402 and the reverse flange 403 are engaged, thereby preventing slag blockage and blocking the slag outside the gas path to maintain smooth airflow.

[0032] Among them, the positive flange 402 can be made of fluorosilicone rubber material, which has good heat resistance and can maintain its shape in the hot bed environment of 3D printing. It can also deform and smoothly pass over the reverse flange 403. The reverse flange 403 can be integrated on the loading platform 2 through milling. It has high structural strength and is not easy to be broken. In particular, the processed inclined surface is relatively smooth and will not block the positive flange 402 due to friction.

[0033] As for the adsorbent colloid 203, it is used as a consumable material and may need to be replaced frequently. The fluororubber ring 4 used here and the plug 202 are interferingly fitted by groove engagement. All fluororubber rings 4 are connected together by a loose high-temperature resistant wire mesh, and the adsorbent colloid 203 is peeled off by pulling the high-temperature resistant wire mesh. The adsorbent colloid 203 and the fluororubber ring 4 can be installed by using a clamp with multiple holes to press them onto the plug 202, so that the installation is completed at one time.

[0034] See attached Fig. 9 and Fig.10The plug 202 needs some assistance to be inserted tightly, especially when the instantaneous pressure of the airflow is relatively large. In order to prevent the plug 202 from being pushed open, in this embodiment, an inner magnet 502, a clamping member 602 for supporting the inner magnet 502, a first elastic member 603 bonded to the outer side of the clamping member 602, and an alloy skeleton 604 are sequentially bonded inside the air storage tank 205 along the axial direction of the micropore 201. The alloy skeleton 604 radiating the lower wall of the entire air storage tank 205 is used to support multiple clamping members 60 2. In order to tighten the plug 202, an external magnet 501 for attracting the internal magnet 502 and the magnetic material is embedded in the end of the plug 202 away from the loading platform 2. The internal magnet 502 attracts the external magnet 501 in the microhole 201 to insert the plug 202 into the clamping piece 602. At the same time, an inner bent pin 601 that fits the clamping piece 602 is welded on the other end of the plug 202 and engages with the clamping piece 602 to achieve the plug 202 being tightly inserted into the microhole 201.

[0035] Furthermore, before the consumable part 3 is formed by the mold, magnetic materials such as neodymium iron boron magnets, samarium cobalt magnets, aluminum nickel cobalt magnets, etc. can be placed inside the mold and made into a shape that adapts to the mold. The consumable part 3 can be placed on the loading platform 2 to attract the external magnet 501 and the internal magnet 502 to achieve vertical positioning of the consumable part 3, and cooperate with the remaining part of the plug 202 to horizontally position the consumable part 3, so as to facilitate the consumable part 3 to remain stable and prevent it from being pushed open by airflow.

[0036] Furthermore, the two inward-bending pins 601 are symmetrically arranged, and there are two arc-shaped bends on the inward-bending pins 601, namely an upper bend and a lower bend. The two clamping members 602 are arranged in an open shape, and the opening has an arc. When the plug 202 is in an exposed state, the lower bend is engaged with the opening, and when the plug 202 is in an inserted state, the lower bend descends along the middle of the two clamping members 602, and the upper bend is engaged with the opening.

[0037] See attached Figure 8 , Fig. 9 and Fig.10 During the biting process, the upper bend and the opening require a larger biting force to achieve clamping. Therefore, in this embodiment, a second elastic member 605 is bonded to one end of the inner bend pin 601 close to the alloy frame 604. The second elastic member 605 is in a double ring shape and can continuously squeeze the opening to bite the upper bend or the lower bend. Limiting columns 606 welded to the inner wall of the air storage tank 205 are embedded in the four corners of the alloy frame 604 to reinforce the roots of the clamping member 602 and the second elastic member 605, so as to securely limit the inner bend pin 601.

[0038] See attached Figure 2 and Figure 3, dust on the surface of the recycled material will reduce the quality of the printed part, so a silo 14 and a guide wheel tube 16 for winding the recycled material are fixed on the back of the chassis by screws, and the recycled material wire is sealed and stored in the silo 14, and a winding roller 15 for winding the recycled material is rotatably installed in the middle of the silo 14. When printing, one end of the recycled material wire is led out through the guide wheel tube 16 and sent to the print head 1 for printing, and the three-dimensional displacement system is controlled to lower the loading platform 2 along the Y axis, and the layered additive printing is performed to process the printed part, which can be annular, cylindrical, special-shaped parts, etc., for example Fig.11 The gear parts in the printing part are adapted to make the consumable part 3 into a ring shape, so that the airflow is distributed to both sides of the printing part and will not blow to the printing point.

[0039] See attached Figure 4 and Figure 5 A cooling fan 17 and a slide rail 18 connected to the three-dimensional displacement system are installed on the print head 1 at intervals. After the cooling fan 17 is started, the blowing direction is offset from the loading platform 2 to dissipate the heat of the print head 1. At the same time, under the drive of the three-dimensional displacement system along the X-axis, the print head 1 and the cooling fan 17 both move along the slide rail 18 to facilitate maintaining balance.

[0040] See attached Figure 1 and Figure 3 The chassis is sealed by an airtight door and can be opened only after the harmful gases are emptied. Therefore, the exhaust gas needs to be discharged independently. In this embodiment, an air collecting hood 19 facing the loading platform 2 and a bellows 21 connected to the air collecting hood 19 are fixed on the top of the chassis by screws. The exhaust gas is drained through the air collecting hood 19 and the bellows 21 and discharged into the exhaust gas treatment equipment. An exhaust fan 20 for attracting the air flow inside the chassis is fixed at the air inlet of the air collecting hood 19 by screws. The exhaust fan 20 is started to suck the exhaust gas to form a circulating airflow to ensure smooth exhaust of the chassis.

[0041] The air intake mechanism and the exhaust fan 20 simultaneously actuate the airflow to achieve rapid discharge of harmful gases, and prevent these airflows from generating vortices inside the chassis, so that the airflow flows in an orderly manner outside the printed part, achieving controllable emission of harmful gases and preventing disturbances to the printing points.

[0042] See attached Figure 2 and Figure 4 The discharge of harmful gases requires an airflow of a certain pressure. The air intake mechanism of this embodiment includes an air intake pipe 9, a connecting pipe 10 and a one-way valve 11 which are connected to the air storage tank 205 in sequence. The air inlet of the one-way valve 11 is connected to an air source. The air source is opened to ventilate the inside of the chassis. The one-way valve 11 is used to limit the airflow to flow into the inside of the chassis. The air intake pipe 9 is set to four and distributed on the four sides of the air storage tank 205. The connecting pipe 10 divides the airflow into four streams and flows to all micropores 201 as much as possible, reducing the micropores 201 that do not emit air, and reducing the airflow pressure to prevent the plug 202 from being pushed open due to excessive pressure.

[0043] See attached Figure 2 and Figure 4 The air inlet of the one-way valve 11 is connected to the air tank 13 and the air pump 12 in sequence. When the air pump 12 is turned on, the clean air in the air-conditioning system can be sucked into the air tank 13 first. When the internal pressure of the air tank 13 reaches the set value, the one-way valve 11 is pushed open, so as to ensure that the airflow has a sufficiently high pressure.

[0044] After printing is completed, the cooled print is removed, the consumable part 3 is lifted, and the plug 202 is pulled up by the magnetic attraction of the built-in magnetic material to automatically detach from the micropore 201, and then the consumable part 3 is broken to take out the magnetic material for recycling.

[0045] Alternatively, the staff can use a permanent magnet or an electromagnet to translate on the loading platform 2 to attract the external magnet 501, and use the suction force to drive the plug 202 to protrude upward from the microhole 201. At this time, the upper bend disengages from the clamping piece 602 and is limited at the lower edge of the microhole 201, while the lower bend re-engages with the clamping piece 602 to prevent the plug 202 from disengaging.

[0046] The working principle of the present invention is as follows: when working, the consumable parts 3 of preset shapes are laid on the loading platform 2 to pad the bottom of the printed part, the print head 1 is moved on the X-axis and Z-axis through the three-dimensional displacement system, and the loading platform 2 is raised and lowered on the Y-axis. The upper surface of the consumable parts 3 is used as the reference plane to open the spraying of recycled material, and the laser beam is used to melt and form quickly. In this process, the air intake mechanism is started to blow airflow.

[0047] At the same time, the consumable part 3 presses down part of the plug 202 to drive the adsorbent colloid 203 and the air outlet 204 into the micropore 201, and the remaining adsorbent colloid 203 and the air outlet 204 are exposed to the outside. When air is taken in, the air flow enters the air storage tank 205 and is distributed to the opened micropore 201, so that the remaining air outlet 204 blows the air flow, and the air flow is vertically distributed to the inside and outside of the printout, taking away the toxic gas while dissipating the heat for the printout, and the adsorbent colloid 203 can absorb the harmful gas and expand, further closing the micropore 201, avoiding air leakage from blowing to the printing point, and realizing stable restriction of the air flow to keep the printing point away.

[0048] Once the plug 202 is inserted into the micropore 201, the reverse flange 403 and the air outlet 204 are driven to sink into the micropore 201, so that the reverse flange 403 passes over the positive flange 402 and then rebounds, and then engages with the positive flange 402 to limit the plug 202. The plug 202 can be limited and will not be pushed out of the micropore 201 when exposed to wind. During this process, the air pore 401 is continuously open, which is convenient for the adsorbent colloid 203 to absorb harmful gases and expand. At the same time, the reverse flange 403 is pushed to adhere to the wall in the micropore 201, and the closure is tighter, which is conducive to preventing air leakage.

[0049] Furthermore, the inner magnet 502 attracts the outer magnet 501 in the microhole 201, so that the plug 202 is inserted into the clamp 602. At the same time, the inner bent pin 601 welded on the other end of the plug 202 and fitting with the clamp 602 is engaged with the clamp 602, so that the plug 202 is tightly inserted into the microhole 201.

[0050] After printing is completed, the cooled print is removed, the consumable part 3 is lifted, and the plug 202 is pulled up by the magnetic attraction of the built-in magnetic material to automatically detach from the micropore 201, and then the consumable part 3 is broken to take out the magnetic material for recycling.

[0051] Alternatively, the staff can use a permanent magnet or an electromagnet to translate on the loading platform 2 to attract the external magnet 501, and use the suction force to drive the plug 202 to protrude upward from the microhole 201. At this time, the upper bend disengages from the clamping piece 602 and is limited at the lower edge of the microhole 201, while the lower bend re-engages with the clamping piece 602 to prevent the plug 202 from disengaging.

[0052] Embodiment 2: The structure is basically the same as that of the first embodiment, except that: a device for processing precision plastic parts of recycled materials. Compared with the method of blowing airflow along the micropores 201 toward the outside of the loading platform 2 in the first embodiment, this embodiment adopts an air pump 12 to suck the airflow inside the chassis, and the one-way valve 11 restricts the airflow from flowing to the outside of the chassis, so that the airflow is sucked into the micropores 201, and activated carbon is filled in the gas tank 13 to absorb harmful gases in the airflow.

[0053] The adsorbent colloid 203, the fluororubber ring 4, the positive flange 402, and the reverse flange 403 on the plug 202 are also removed. After the plug 202 is pressed into the micropores 201, all micropores 201 maintain smooth airflow, generating a certain suction force to absorb the consumable part 3. This saves the steps of disassembling and assembling the adsorbent colloid 203 and simplifies the printing steps.

[0054] The magnetic material and the magnetic attraction between the inner magnet 502 and the outer magnet 501 can vertically position the consumable part 3. The remaining part of the plug 202 can horizontally position the consumable part 3, so that the consumable part 3 can stably carry the printed part.

[0055] At this time, the exhaust fan 20 is used to suck clean air from the air conditioning system and send it into the interior of the chassis, so as to shift the direction of the airflow away from the print head 1.

[0056] The above is only an optional implementation of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
