Description

Technical Field

[0001] The invention relates to the technical field of UV inkjet printers, and in particular to a color UV inkjet printer. Background Art

[0002] Color UV inkjet printer is a kind of inkjet equipment that uses UV (ultraviolet) curing technology to accurately spray color ink onto the surface of objects and quickly cure the ink through ultraviolet irradiation. It can achieve high-resolution and high-definition color inkjet marking on various materials and is widely used in food, medicine, daily chemicals, electronics, building materials and other industries.

[0003] In the actual coding process, some large items cannot be processed by batch coding using the conveyor line, or when re-coding missed items, a flexible and movable color UV inkjet printer is required to implement individual coding.

[0004] Some of the existing UV inkjet printers are equipped with multiple ground-contact support structures for supporting the wheels to stably support the base and the nozzle assembly. At the same time, these ground-contact support structures can also level the base. However, there is a lack of a mechanism for transmitting synchronous driving force between the driving mechanisms of the multiple ground-contact support structures. As a result, when the wheels are lifted and lowered, they cannot be driven to rise and fall synchronously at one time, but need to be driven step by step, which is cumbersome and inefficient to operate.

[0005] In addition, although some of the ground contact support structures are equipped with mechanisms for transmitting synchronous driving force between their driving mechanisms and can implement synchronous driving, the multiple ground contact support structures can no longer be driven individually after being synchronously driven, and the base cannot be leveled. As a result, the multiple ground contact support structures cannot simultaneously take into account synchronous driving and independent driving, and cannot take into account both rapid take-off and landing of the wheels and normal leveling of the base, resulting in poor use effect. Summary of the invention

[0006] In view of this, the present invention provides a color UV inkjet printer to solve the problem that after multiple ground-contact support structures are synchronously driven, they can no longer be driven individually, and both the rapid take-off and landing of the wheels and the normal leveling of the base cannot be taken into account, resulting in poor use effect.

[0007] The technical solution proposed by the present invention is: a color UV inkjet printer, specifically comprising: a bracket base, a main unit and a knob ring, wherein the bracket base is used to support and install a nozzle;

[0008] The support base as a whole is composed of two horizontal and two vertical support rods welded together, wherein synchronous wheels are rotatably installed on the top sides of both ends of the two horizontal support rods, and a synchronous belt is tensioned between the four synchronous wheels; four ground-contacting support plates are symmetrically and slidably installed below the bottom side of the support base, and a vertically arranged threaded propulsion shaft is welded at the middle of the top of the ground-contacting support plate; positioning sleeves are welded on the top sides of the two horizontal support rods of the support base near the four synchronous wheels, and the threaded propulsion shaft is slidably fitted with the horizontal support rods and positioning sleeves of the support base; relay gears are rotatably mounted on the positioning sleeves at the four locations. Wheel, a force ring is welded on the top of the relay gear; the top sides of the two end parts of the horizontal support rods at the two places of the bracket base are welded with a U-shaped support frame, and the middle positions of the tops of the four U-shaped support frames are penetrated and rotatably installed with threaded sleeves, and the bottom ends of the threaded sleeves are welded with force transmission rings, and knob rings are slidably installed on the four force transmission rings; a circle of vertical transmission shaft is welded around and penetrated on the knob ring, and the vertical transmission shaft is pushed and slidably matched with the force ring through the spring; the relay gears at the four places correspond to the meshing transmission with the four synchronous wheels at the four places, and under normal conditions, the bottom side protrusions of a circle of vertical transmission shafts are plug-fitted with the force ring;

[0009] The circumferential outer ring of the ground contact support plate is welded with a vertical positioning shaft, and the vertical positioning shaft and the horizontal support rod of the bracket base are penetrated and slidably matched; the bottom sides of both ends of the horizontal support rods at the two places of the bracket base are threaded to fasten the wheels; the wheels are used to roll the bracket base to adjust the working position of the UV nozzle, and when the inkjet printer is in use, the four wheels need to be lifted from the ground, and the four ground contact support plates are lowered and supported against the ground, so as to provide stable support for the UV nozzle by the bracket base; the forward and reverse rotation of the threaded sleeve can drive the threaded propulsion shaft and the ground contact support plate to slide up and down;

[0010] When the four ground-contact support plates are synchronously moved downward and abutted against the ground support, the four wheels can be lifted from the ground. When the four ground-contact support plates are synchronously slid upward and separated from the ground, the wheels can be lowered and placed on the ground. When the four ground-contact support plates are raised and lowered and slid separately, the bracket base and UV nozzle can be leveled.

[0011] The four synchronous wheels are connected through synchronous belt transmission, and the four relay gears are meshed with the four synchronous wheels for transmission. When the four-circle vertical transmission shaft on the four knob rings slide down and plug into the four force rings, the four threaded sleeves can be indirectly connected by the synchronous belt. At this time, the rotation drive of any threaded sleeve can drive all the threaded sleeves to rotate together, and the four ground contact support plates are driven to rise and fall synchronously at one time to raise and lower the wheels. Compared with the existing technology, the trouble of lifting and lowering multiple ground contact support plates in steps is eliminated, making the lifting and lowering operation of the wheels convenient and quick.

[0012] When the four-circle vertical transmission shaft is slid upward and the four force-bearing rings are pulled out for power decoupling, the power connection between the threaded propulsion shaft and the synchronous belt can be interrupted, so that the threaded propulsion shaft can be rotated alone to drive the bracket base and the UV nozzle to level;

[0013] The relay gear that can slide up and down is actually a power clutch mechanism of the threaded sleeve and the synchronous belt. Through this clutch mechanism, the driving mode of the threaded sleeve and the four threaded propulsion shafts can be freely switched, so that the four threaded propulsion shafts are synchronously driven when the four synchronous wheels are synchronously taken off and lowered, and the four threaded propulsion shafts are separately driven independently when the bracket base is leveled, so that the synchronous drive and the separate independent drive of the four ground contact support plates do not interfere with each other. Compared with the existing technology, it can take into account both the rapid take-off and landing of the wheels and the normal leveling of the bracket base, and has better practicality.

[0014] Furthermore,

[0015] The lower half of the threaded propulsion shaft is a polished rod structure, and the upper half is provided with threads. The polished rod part of the threaded propulsion shaft is slidably matched with the transverse support rod of the bracket base, and a gap is maintained between the threaded propulsion shaft and the positioning sleeve.

[0016] Furthermore,

[0017] Under normal circumstances, the knob ring slides down and rests on the force ring. The knob ring is used to drive the threaded sleeve with a knob. It can directly slide up and down when driving the threaded sleeve with a knob, and switch and adjust the driving mode of the threaded sleeve and the threaded propulsion shaft without the need for additional manual operation steps. The operation is simple and convenient.

[0018] Furthermore,

[0019] The top ends of the two longitudinal support rods at the bracket base are commonly threadedly fastened with vertical pillars, on which horizontal support rail rods are slidably installed, and on which UV nozzles are slidably installed, and a paint conduit and a data cable are connected between the UV nozzles and the host.

[0020] Furthermore,

[0021] The cross sections of the vertical support pillars and the horizontal support rail rods are both I-shaped structures.

[0022] Furthermore,

[0023] The two longitudinal support rods of the bracket base are welded to the middle position between the two transverse support rods of the bracket base.

[0024] Furthermore,

[0025] The positioning sleeve and the synchronous wheel are located inside the U-shaped support frame, and the U-shaped support frame can shield and protect the positioning sleeve and the synchronous wheel from collision, thereby reducing the probability of the positioning sleeve and the synchronous wheel being damaged by collision. Therefore, the U-shaped support frame can be used to support and install the threaded sleeve, and can also be used to protect the positioning sleeve and the synchronous wheel from collision. It has the effect of using one device for two purposes, and can save the need to configure an additional anti-collision structure for the positioning sleeve and the synchronous wheel, which helps to simplify the overall structure of the inkjet printer to a certain extent.

[0026] Furthermore,

[0027] A limiting ring is arranged at the top end of the positioning sleeve, and the top end of the force-bearing ring is rotationally fitted with the limiting ring.

[0028] Furthermore,

[0029] The upper part of the threaded sleeve is provided with two limiting rings at intervals, and the two limiting rings are rotatably fitted with the upper and lower ends of the horizontal bracing side rods at the top end of the U-shaped support frame.

[0030] The technical solution proposed by the present invention is: a method for using a color UV inkjet printer, comprising the following operating steps:

[0031] ① First, move the bracket base and the host to the conveying device for conveying the product to be coded, and place the nozzle on the top of the conveying device;

[0032] ② Then, the four ground-contact support plates are driven to slide downward to lift the four wheels;

[0033] ③. Then, lift and adjust the four ground-contact support plates respectively to level the bracket base;

[0034] ④. Adjust the UV nozzle by lifting and lowering, sliding horizontally on the vertical support and the horizontal rail rod, so that the UV nozzle is centered on the product to be coded on the conveying device;

[0035] ⑤. Finally, start the host and conveying device to start the inkjet coding process for the continuously conveyed products.

[0036] The present invention provides a color UV inkjet printer, which has the following beneficial effects:

[0037] According to the present invention, the vibration motor and the rotating wheel can be rotated to drive the strip drive frame, the pipe sleeve and the paint conduit to vibrate up and down through the dial shaft. After the inkjet printer has been idle for a long time, the paint that has been statically settled and precipitated in the paint conduit is pre-vibrated and tumbled to dissolve, so as to avoid clogging the UV nozzle when the inkjet printer is reused. During the use of the inkjet printer, the paint in the paint conduit can also be continuously vibrated and tumbled to dissolve through the strip drive frame and the pipe sleeve, so as to avoid the paint precipitating and being retained in the paint conduit during long-term use, thereby clogging the paint conduit and the UV nozzle, which helps to ensure the normal and effective use of the UV nozzle for a long time.

[0038] In addition, the bracket base and the main machine are transferred to the conveying device that transports the products to be coded, and the UV nozzle is placed on the top of the conveying device. Then, the four ground-contacting support plates are driven downward synchronously to lift up the four wheels. Then, the four ground-contacting support plates are raised and lowered respectively to level the bracket base. Then, the UV nozzle is raised and lowered and horizontally slid on the vertical pillars and horizontal support rails to center the UV nozzle on the products to be coded on the conveying device. Finally, the main machine and the conveying device are started to start coding processing for continuously conveyed large products.

[0039] In addition, the four synchronous wheels are connected through synchronous belt transmission, and the four relay gears are meshed with the four synchronous wheels for transmission. When the four-circle vertical transmission shaft on the four knob rings slide down and engage with the four force rings, the four threaded sleeves can be indirectly connected by the synchronous belt. At this time, the rotation drive of any threaded sleeve can drive all the threaded sleeves to rotate together, and the four ground-contact support plates are driven to rise and fall synchronously at one time, and the wheels are raised and lowered, which is convenient for switching the entire equipment to a moving or stable placement state.

[0040] In addition, the relay gear that can slide up and down is actually a power clutch mechanism of the threaded sleeve and the synchronous belt. Through this clutch mechanism, the driving mode of the threaded sleeve and the four threaded propulsion shafts can be freely switched, so that when the four synchronous wheels are synchronously taken off and lowered, the four threaded propulsion shafts are synchronously driven, and when the bracket base is leveled, the four threaded propulsion shafts are driven separately and independently, so that the synchronous drive and the separate independent drive of the four ground contact support plates do not interfere with each other. Compared with the existing technology, it can take into account both the rapid take-off and landing of the wheels and the normal leveling of the bracket base, which is convenient for inkjet coding.

[0041] In addition, the U-shaped support frame can shield and protect the positioning sleeve and the synchronous wheel from collision, reducing the chance of the positioning sleeve and the synchronous wheel being damaged by collision. Therefore, the U-shaped support frame can be used to support and install the threaded sleeve, and can also be used to protect the positioning sleeve and the synchronous wheel from collision. It has the effect of serving two purposes in one, and can save the need for additional anti-collision structures for the positioning sleeve and the synchronous wheel, which helps to simplify the overall structure of the inkjet printer to a certain extent.

[0064] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0065] Please refer to Figures 1 to 8 , Embodiment 1:

[0066] The present invention proposes a color UV inkjet printer, comprising: a bracket base 1, a U-shaped support frame 101, a threaded sleeve 102, a force transmission ring 1021, a knob ring 103, a vertical transmission shaft 1031, a positioning sleeve 104, a relay gear 105, a force ring 1051, a host 2, a UV nozzle 3, a vertical support 4, a synchronous belt 5, a ground contact support plate 6, a threaded propulsion shaft 601, a vertical positioning shaft 602, a synchronous wheel 7, a wheel 8, and a horizontal support rail rod 9. The bracket base 1 is used for supporting and installing the UV nozzle 3;

[0067] Among them, the support base 1 as a whole is composed of two horizontal and two vertical support rods welded together, among which the top sides of both ends of the two horizontal support rods are rotatably installed with synchronous wheels 7, and the tensioning sleeves of the four synchronous wheels 7 are equipped with synchronous belts 5; four ground-contacting support plates 6 are symmetrically and slidably installed below the bottom side of the support base 1, and a vertically arranged threaded propulsion shaft 601 is welded at the middle of the top of the ground-contacting support plate 6; positioning sleeves 104 are welded on the top sides of the two horizontal support rods of the support base 1 near the four synchronous wheels 7, and the threaded propulsion shaft 601 is slidably matched with the horizontal support rods and positioning sleeves 104 of the support base 1; relay gears 105 are rotatably installed on the four positioning sleeves 104, and a force ring 1051 is welded on the top of the relay gear 105; the top sides of the two end parts of the two horizontal support rods of the support base 1 are welded with a U-shaped support frame 1 01, the top middle position of the four U-shaped support frames 101 is penetrated and rotatably installed with a threaded sleeve 102, the bottom end of the threaded sleeve 102 is welded with a force transmission ring 1021, and the four force transmission rings 1021 are slidably installed with a knob ring 103; a circle of vertical transmission shaft 1031 is welded around and penetrated on the knob ring 103, and the vertical transmission shaft 1031 is pushed and slidably matched with the force ring 1051 through a spring; the four relay gears 105 are meshed and transmitted with the four synchronous wheels 7, and under normal conditions, the bottom side protrusions of a circle of vertical transmission shaft 1031 are plugged and matched with the force ring 1051; the circumferential outer ring of the ground contact support plate 6 is welded with a vertical positioning shaft 602, and the vertical positioning shaft 602 is penetrated and slidably matched with the horizontal support rod of the bracket base 1; the bottom sides of the two ends of the horizontal support rods of the bracket base 1 are threaded to fasten the wheels 8;

[0068] The wheels 8 are used to roll the transfer bracket base 1 to adjust the working position of the UV nozzle 3. When the inkjet printer is in use, the wheels 8 at four sides need to be lifted from the ground, and the four ground-contacting support plates 6 need to be lowered and supported against the ground, so as to provide stable support for the UV nozzle 3 by the bracket base 1; the forward and reverse rotation of the threaded sleeve 102 can drive the threaded propulsion shaft 601 and the ground-contacting support plate 6 to move up and down;

[0069] When the four-way ground-contact support plate 6 is synchronously moved downward and abutted against the ground support, the four-way wheels 8 can be lifted from the ground. When the four-way ground-contact support plate 6 is synchronously slid upward and separated from the ground, the wheels 8 can be dropped and placed on the ground. When the four-way ground-contact support plate 6 is separately raised and lowered and slid, the bracket base 1 and the UV nozzle 3 can also be leveled.

[0070] The four synchronous wheels 7 are connected by the synchronous belt 5, and the four relay gears 105 are meshed with the four synchronous wheels 7 for transmission. When the four circles of vertical transmission shafts 1031 on the four knob rings 103 slide down and plug into the four force rings 1051, the four threaded sleeves 102 can be indirectly connected by the synchronous belt 5. At this time, the rotation drive of any threaded sleeve 102 can drive all the threaded sleeves 102 to rotate together, and the four ground contact support plates 6 are driven to rise and fall synchronously at one time, so as to raise and lower the wheels 8. Compared with the prior art, the trouble of raising and lowering the multiple ground contact support plates 6 in steps is eliminated, so that the raising and lowering operation of the wheels 8 is convenient and quick.

[0071] When the four-circle vertical transmission shaft 1031 is slid upward and the four-circle force ring 1051 is pulled out of the power decoupling, the power connection between the threaded propulsion shaft 601 and the synchronous belt 5 can be interrupted, so that the threaded propulsion shaft 601 can be rotated alone to drive the bracket base 1 and the UV nozzle 3 to level;

[0072] The relay gear 105 that can slide up and down is actually a power clutch mechanism of the threaded sleeve 102 and the synchronous belt 5. Through this clutch mechanism, the threaded sleeve 102 and the four threaded propulsion shafts 601 can be freely switched to drive the four threaded propulsion shafts 601 synchronously when the four synchronous wheels 7 are synchronously taken off and lowered, and the four threaded propulsion shafts 601 are driven separately and independently when the support base 1 is leveled, so that the synchronous drive and the separate independent drive of the four ground contact support plates 6 do not interfere with each other. Compared with the prior art, it can take into account both the rapid take-off and landing of the wheels 8 and the normal leveling of the support base 1, and has better practicality.

[0073] The vertical positioning shaft 602 is used to block the limited ground contact support plate 6 and the threaded propulsion shaft 601, so as to prevent the ground contact support plate 6 and the threaded propulsion shaft 601 from rotating together with the threaded sleeve 102 and failing to be normally and effectively driven to rise and fall.

[0074] Preferably,

[0075] The lower half of the threaded propulsion shaft 601 is a polished rod structure, and the upper half is provided with threads. The polished rod portion of the threaded propulsion shaft 601 is slidably matched with the transverse support rod of the bracket base 1, and a gap is maintained between the threaded propulsion shaft 601 and the positioning sleeve 104.

[0076] Preferably,

[0077] Under normal conditions, the knob ring 103 slides down and rests against the force ring 1051;

[0078] The knob ring 103 is used to drive the threaded sleeve 102. When the threaded sleeve 102 is driven by the knob, it can directly slide up and down to switch and adjust the driving mode of the threaded sleeve 102 and the threaded propulsion shaft 601 without additional manual operation steps. The operation is simple and convenient.

[0079] Preferably,

[0080] The top ends of the two longitudinal support rods at the bracket base 1 are commonly threadedly fastened with vertical pillars 4, on which horizontal support rail rods 9 are slidably mounted, and on which UV nozzles 3 are slidably mounted, and a paint conduit and a data cable are connected between the UV nozzles 3 and the host 2.

[0081] Preferably,

[0082] The cross sections of the vertical support pillars 4 and the horizontal rail rods 9 are both I-shaped structures.

[0083] Preferably,

[0084] The two longitudinal support rods of the support base 1 are welded to the middle position between the two transverse support rods of the support base 1 .

[0085] Preferably,

[0086] The positioning sleeve 104 and the synchronous wheel 7 are located inside the U-shaped support frame 101. The U-shaped support frame 101 can shield and protect the positioning sleeve 104 and the synchronous wheel 7 from collision, thereby reducing the probability of the positioning sleeve 104 and the synchronous wheel 7 being damaged by collision. Therefore, the U-shaped support frame 101 can be used to support and install the threaded sleeve 102, and can also be used to protect the positioning sleeve 104 and the synchronous wheel 7 from collision. It has the effect of being a device with two uses, and can save the need to configure an additional anti-collision structure for the positioning sleeve 104 and the synchronous wheel 7, which helps to simplify the overall structure of the inkjet printer to a certain extent.

[0087] Preferably,

[0088] A limiting ring is provided at the top of the positioning sleeve 104, and the top of the force ring 1051 is rotationally fitted with the limiting ring.

[0089] Preferably,

[0090] The upper half of the threaded sleeve 102 is provided with two limiting rings at upper and lower intervals, and the two limiting rings are correspondingly and rotatably attached to the upper and lower ends of the horizontal support rod at the top of the U-shaped support frame 101.

[0091] On the basis of Embodiment 1, Embodiment 2:

[0092] The present invention also proposes a method for using a color UV inkjet printer, including the following operating steps:

[0093] ①. First, transfer the support base 1 and the main unit 2 to the conveying device for conveying the product to be inkjet-printed, and place the UV nozzle 3 at the top of the conveying device;

[0094] ②. Then, synchronously drive the four ground-touching support disks 6 to slide downward to lift the four wheels 8;

[0095] ③. Subsequently, respectively lift and lower and adjust the four ground-touching support disks 6 to level the support base 1;

[0096] ④. On the vertical support column 4 and the cross撑轨道杆9 (it seems there is a wrong expression here, assuming it should be a correct part name), lift, lower, and horizontally slide to adjust the UV nozzle 3 so that the UV nozzle 3 is centered and aligned with the product to be inkjet-printed on the conveying device;

[0097] ⑤. Finally, start the main unit 2 and the conveying device to start inkjet-printing the continuously conveyed products.

[0098] On the basis of Embodiment 1, Embodiment 3, as Fig. 9 and Fig.10 shown:

[0099] The present invention also proposes a color UV inkjet printer, including a vibration motor 10, a runner 1001, a dial shaft 1002, a U-shaped positioning frame 401, a strip-shaped driving frame 402, and a pipe sleeve 403. The top part of the vertical support column 4 is threadedly fastened with a vibration motor 10. The first end of the rotating shaft of the vibration motor 10 is sleeved with a runner 1001, and a dial shaft 1002 is welded to the outer circumference of the runner 1001; two U-shaped positioning frames 401 are symmetrically welded on both sides of the top part of the vertical support column 4 where the vibration motor 10 is located. A strip-shaped driving frame 402 is slidably installed on the vertical support shafts of the two U-shaped positioning frames 401. Pipe sleeves 403 are welded at intervals in the middle part of the strip-shaped driving frame 402. A silica gel gasket is fixed on the inner circumference of the pipe sleeve 403. The paint conduit passes through the pipe sleeve 403, and the dial shaft 1002 is inserted and matched with the strip-shaped driving frame 402;

[0100] Through the dial shaft 1002, the vibration motor 10 and the rotating wheel 1001 can rotate to drive the bar drive frame 402, the tube sleeve 403 and the paint conduit to vibrate up and down. After the inkjet printer has been idle for a long time, the paint that has settled and precipitated in the paint conduit is pre-vibrated and tumbled to dissolve, so as to avoid clogging the UV nozzle 3 when it is reused. In addition, during the use of the inkjet printer, the paint inside the paint conduit can also be continuously vibrated and tumbled to dissolve through the bar drive frame 402 and the tube sleeve 403, so as to avoid the paint precipitating and staying in the paint conduit during long-term use, thereby clogging the paint conduit and the UV nozzle 3, which helps to ensure the normal and effective use of the UV nozzle 3 for a long time.

[0101] The silicone gasket can reduce the relative wear between the pipe sleeve 403 and the paint conduit during vibration.

[0102] Working principle: The wheels 8 are used to roll the transfer bracket base 1 to adjust the working position of the UV nozzle 3. When the inkjet printer is in use, the wheels 8 at four locations need to be lifted from the ground, and the four ground-contacting support plates 6 need to be lowered and supported against the ground to provide stable support for the bracket base 1 to the UV nozzle 3. The forward and reverse rotation of the threaded sleeve 102 can drive the threaded propulsion shaft 601 and the ground-contacting support plate 6 to move up and down.

[0103] When in use, first transfer the support base 1 and the host 2 to the conveying device for conveying the product to be coded, and place the UV nozzle 3 on the top of the conveying device, then synchronously drive the four ground-contacting support plates 6 to slide downward to lift the four wheels 8, then lift and adjust the four ground-contacting support plates 6 respectively, level the support base 1, then lift and lower and horizontally slide the UV nozzle 3 on the vertical support pillars 4 and the horizontal support rail rods 9, so that the UV nozzle 3 is centered and aligned with the product to be coded on the conveying device, and finally start the host 2 and the conveying device to start coding the continuously conveyed products;

[0104] The knob ring 103 is used to perform knob drive on the threaded sleeve 102. When the knob drive is performed on the threaded sleeve 102, it can directly slide up and down, and the driving mode of the threaded sleeve 102 and the threaded propulsion shaft 601 is switched and adjusted. The vertical positioning shaft 602 is used to block the limited ground support plate 6 and the threaded propulsion shaft 601 to prevent the ground support plate 6 and the threaded propulsion shaft 601 from rotating with the threaded sleeve 102 and cannot be driven normally and effectively to rise and fall.

[0107] 2. In the absence of conflict, the embodiments of the present invention and the features therein may be combined with each other to obtain new embodiments.

[0108] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
