[0010] A swing cleaning mechanism, which is arranged in the housing and is used to clean stains on the lens;

[0011] The liquid delivery pump is used to extract the cleaning liquid in the liquid storage box and deliver it to the atomizing sheet.

[0012] By adopting the above technical solution, when the lens needs to be cleaned, the cleaning liquid in the liquid storage box is transported to the atomizing sheet through the liquid delivery pump, the cleaning liquid is atomized by the atomizing sheet and sprayed onto the lens, and then the lens is scrubbed by the swinging cleaning mechanism, thereby effectively cleaning the dust, oil and other impurities on the lens, ensuring the use effect of the lens, and the cleaning is carried out automatically without manual operation, which is more convenient to use.

[0013] The present invention is further configured as follows: the liquid delivery pump comprises:

[0014] A pump body, wherein a first inlet is provided at one end of the pump body, a first outlet is provided at one side of the pump body, and a first one-way valve is provided at the first inlet;

[0015] A sliding core, wherein the sliding core is divided into a liquid delivery chamber and a driving chamber, a second inlet connected to the liquid delivery chamber is provided on one end of the sliding core, a second outlet connected to the liquid delivery chamber is provided on one side of the sliding core, a second one-way valve is provided at the second inlet, and a sliding core driving mechanism is provided in the driving chamber for driving the sliding core to slide in the pump body;

[0016] The outer wall of the sliding core is slidingly and sealingly connected to the inner wall of the pump body through a sealing ring, and the pump body is divided into a first variable-volume space and a second variable-volume space by the sliding core and the sealing ring. The first variable-volume space is connected to the first inlet and the second inlet, and the second variable-volume space is connected to the first outlet and the second outlet. The first outlet is connected to the two atomizing sheets through a conduit, and the liquid storage box is connected to the first inlet.

[0017] By adopting the above technical solution, when the sliding core slides to the left, the first variable volume space becomes larger and generates negative pressure, the first one-way valve opens, and the second one-way valve closes, so that the cleaning liquid in the liquid storage box is drawn into the first variable volume space through the first inlet; then the sliding core slides to the right, the first variable volume space becomes smaller, the first one-way valve is closed, and the second one-way valve is opened, and the cleaning liquid in the first variable volume space enters the liquid delivery chamber; when the sliding core slides to the left again, the second variable volume space becomes smaller, so that the cleaning liquid in the liquid delivery chamber is delivered to the atomizing sheet through the second outlet, the first outlet, and the conduit; the overall volume is small, the space occupied is also small, the structure is simple, and the cleaning liquid can be effectively delivered.

[0018] The present invention is further configured as follows: the sliding core driving mechanism comprises:

[0019] First rack;

[0020] Second rack;

[0021] A gear, wherein teeth are provided on an outer wall less than half of the circumference of the gear;

[0022] A micro motor, wherein the micro motor drives the gear to rotate;

[0023] Among them, the first rack and the second rack are respectively arranged on the opposite sides of the driving cavity, the gear is arranged between the first rack and the second rack and is meshed and connected, and the gear can only be meshed and connected with the first rack or the second rack alone. The micro motor is installed outside the pump body, and its output shaft passes through the pump body and the sliding core in sequence and extends into the driving cavity. The sliding core is provided with a long strip opening for the output shaft of the micro motor to slide.

[0024] By adopting the above technical solution, the position of the gear relative to the pump body does not change, and the micromotor drives the gear to rotate counterclockwise. When the gear is engaged with the first rack, it can effectively drive the sliding core to slide to the left. As the gear rotates, it separates from the first rack and then engages with the second rack, thereby driving the sliding core to slide to the right, thereby effectively driving the sliding core to slide back and forth left and right in the pump body. The gear meshing can effectively reduce the noise during operation and extend the service life.

[0025] The present invention is further configured as follows: the first one-way valve and the second one-way valve have the same structure, and the first one-way valve comprises:

[0026] A sealing ball, wherein a cross bar is connected through the sealing ball along the diameter direction of the sealing ball;

[0027] A limiting sleeve, wherein the inner wall of the limiting sleeve is provided with grooves corresponding to the two ends of the cross bar;

[0028] Among them, the middle parts of the first inlet and the second inlet are protruding inward, the minimum inner diameters of the first inlet and the second inlet are smaller than the diameter of the sealing ball, the two ends of the cross bar extend into the corresponding grooves, and the length of the cross bar is smaller than the distance between the bottoms of the two grooves and larger than the inner diameter of the limit sleeve.

[0029] By adopting the above technical solution, when the medium flows from right to left, the sealing ball will move to the left. Under the action of the cross bar, the sealing ball can only move within a certain space, thereby effectively limiting the movement range of the sealing ball and ensuring the action response speed of the sealing ball.

[0030] The present invention is further configured as follows: the swing cleaning mechanism comprises:

[0031] An outer shell is cylindrical, a coil is wound on the outer wall of the outer shell, and the outer shell is fixed in the housing;

[0036] By adopting the above technical scheme, when the swing cleaning mechanism is in the initial state, the coil is not energized, and under the action of the first torsion spring, the swing arm mechanism is in the extreme downward position. When the coil is powered in the positive direction, the coil generates a positive magnetic field, which acts on the magnetic block, thereby driving the rotating bracket to rotate upward in the shell and overcome the force of the first torsion spring, driving the swing arm mechanism to scrub the lens upward until it reaches the extreme upward position, and then the coil is powered in the reverse direction, so that the coil generates a reverse magnetic field, which acts on the magnetic block, thereby driving the rotating bracket to rotate downward in the shell. The first torsion spring also applies a force for the rotating bracket to rotate downward, driving the swing arm mechanism to scrub the lens downward, and changing the direction of the magnetic field by changing the direction of the coil current, thereby realizing the reciprocating swing of the swing arm mechanism to scrub the lens. The mechanism is simple, the size is small, and the noise is low.

[0037] The present invention is further configured as follows: the swing lever mechanism comprises:

[0038] A support rod, wherein a plurality of support rods are provided and connected in sequence;

[0039] Elastic return device;

[0040] Wherein, adjacent support rods are connected via elastic return devices.

[0041] By adopting the above technical solution, the swing rod mechanism can maintain a straight rod state when not affected by external force. When affected by external force, adjacent support rods can bend through the elastic return device, so that the swing rod mechanism can fit the outer circle of the lens as much as possible, so that the surface of the lens can be scrubbed more completely, the scrubbing area is increased, and the cleaning effect is better.

[0042] The present invention is further configured as follows: the elastic return device comprises:

[0043] A first mounting plate, wherein a first limiting rod is protruded from the first mounting plate;

[0044] A second mounting plate, wherein a second limiting rod is protruded from the second mounting plate;

[0045] A central shaft, one end of which is fixed on a side of the second mounting plate facing the first mounting plate, and the other end of which is provided with a blind hole;

[0046] An insert shaft, the insert shaft is fixed on a side of the first mounting plate facing the second mounting plate and is rotationally matched with the blind hole;

[0047] A first ferrule, wherein two first protrusions are protruding from the outer side of the first ferrule;

[0048] A second ferrule, wherein two second protrusions are protruding from the outer side of the second ferrule;

[0049] second torsion spring;

[0050] In which, the first mounting plate and the second mounting plate are respectively arranged on the opposite ends of the two adjacent support rods, the first ferrule and the second ferrule are both sleeved on the outside of the central axis, the first ferrule and the second ferrule are both provided with a torsion spring groove for installing the second torsion spring, the two ends of the second torsion spring are respectively connected to the torsion spring grooves in the first ferrule and the second ferrule, one of the first protrusions on the first ferrule and one of the second protrusions on the second ferrule are clamped on both sides of the first limiting rod, and the other first protrusion on the first ferrule and the other second protrusion on the second ferrule are clamped on both sides of the second limiting rod.

[0051] By adopting the above technical solution, when the swing arm mechanism swings downward, when approaching the lower wall of the channel, the lower end of the support rod below will contact the inner wall of the channel, the support rod is subjected to resistance, and the upper support rod continues to swing under the action of the rotating bracket, so that the two adjacent support rods will rotate along the axis of the central axis. When the lower support rod rotates, the second limit rod connected to the second mounting plate pushes one of the second protrusions, so that the second clamping sleeve rotates relative to the first clamping sleeve, so that the second torsion spring accumulates force; when the swing arm mechanism reaches the limit position of downward movement, the swing arm mechanism moves upward, and as the upper support rod gradually swings upward, under the action of the second torsion spring, the second clamping sleeve returns to its initial position, and the swing arm mechanism maintains a straight rod state. The central axes of the support rods are on the same straight line; when the swing arm mechanism swings upward, the lower end of the support rod below contacts the inner wall of the channel, thereby pushing one of the first protrusions through the second limit rod, so that the first clamping sleeve rotates relative to the second clamping sleeve, and the second torsion spring accumulates force; when the swing arm mechanism swings, the cleaning cloth on the support rod can be as close to the edge of the lens as possible, so that the cleaning area is larger and the action response is faster; the force of the rotating bracket when rotating is greater than the force of the second torsion spring in the elastic return device, and at the same time, when the swing cleaning mechanism is in the initial state and the coil is not energized, the force of the first torsion spring is also greater than the force of the second torsion spring in the elastic return device, so that when the swing cleaning mechanism is not working in the initial state, each support rod can be as close to the inner wall of the channel as possible.

[0052] The present invention is further configured as follows: the elastic return device further comprises:

[0053] A rotating bearing, the rotating bearing being arranged between the central shaft and the contact surface between the first mounting plate and the plug shaft;

[0054] An elastic sleeve is sleeved on the outside of the connection between two adjacent support rods, and the elastic sleeve is arranged on the inner side of the cleaning cloth.

[0055] By adopting the above technical solution, the rotating bearing can make the rotation between the central axis and the first mounting plate and the plug shaft smoother and easier; the elastic sleeve can effectively wrap the elastic return device between adjacent support rods, preventing external water and impurities from entering the elastic return device, thereby ensuring the service life of the elastic return device.

[0056] The present invention is further configured to include:

[0057] An electrostatic generator, the electrostatic generator comprising an anode terminal and a cathode terminal;

[0058] A metal sheet, wherein the metal sheet is attached to the inner wall of the channel;

[0059] The anode end of the electrostatic generator is connected to the cleaning liquid in the liquid storage box and the metal sheet, and the cathode end of the electrostatic generator is connected to the lens.

[0060] By adopting the above technical solution, the electrostatic generator can make the cleaning liquid, metal sheets and lenses in the liquid storage box have static electricity, wherein the cleaning liquid and the metal sheets are positively charged, and the lenses are negatively charged. When the positively charged cleaning liquid is atomized and sprayed through the atomizing sheet, it will be attracted by the negatively charged lenses. Therefore, the cleaning liquid can be evenly sprayed and covered on the surface of the lenses. At the same time, the metal sheets on the inner wall of the channel are also positively charged. Therefore, the cleaning liquid is not easy to float to the inner wall of the channel, so that the effect of spraying the cleaning liquid is better, waste is reduced, and there is no contact or insulation between the metal sheets and the lenses.

[0061] The present invention is further configured to include:

[0062] A drainage hole, the drainage hole is provided below one end of the channel close to the lens;

[0063] A sewage box, the sewage box is arranged in the housing, and a drain port for discharging sewage is provided at the bottom of the sewage box;

[0064] Wherein, the drainage hole is communicated with the sewage box.

[0065] By adopting the above technical solution, when the swing rod mechanism scrubs the surface of the lens, the sewage on the lens will flow into the sewage box through the drainage hole for collection. When the cleaning is completed, the sewage in the sewage box will be discharged from the light-emitting device through the drain port, which is more convenient to use.

[0091] In the embodiment of the present invention, the liquid delivery pump 4 comprises:

[0092] A pump body 40, wherein a first inlet 400 is provided at one end of the pump body 40, a first outlet 401 is provided at one side of the pump body 40, and a first one-way valve is provided at the first inlet 400;

[0093] A slide core 41, wherein the slide core 41 is divided into a liquid delivery chamber 410 and a drive chamber 411, a second inlet 412 connected to the liquid delivery chamber 410 is provided on one end of the slide core 41, a second outlet 413 connected to the liquid delivery chamber 410 is provided on one side of the slide core 41, a second one-way valve is provided at the second inlet 412, and a slide core drive mechanism is provided in the drive chamber 411 for driving the slide core 41 to slide in the pump body 40;

[0094] Among them, the outer wall of the sliding core 41 is slidingly and sealingly connected to the inner wall of the pump body 40 through a sealing ring 414, and the pump body 40 is divided into a first variable-volume space 402 and a second variable-volume space 403 by the sliding core 41 and the sealing ring 414. The first variable-volume space 402 is connected to the first inlet 400 and the second inlet 412, and the second variable-volume space 403 is connected to the first outlet 401 and the second outlet 413. The first outlet 401 is connected to the two atomizing sheets 5 through a conduit 7, and the liquid storage box 3 is connected to the first inlet 400.

[0095] By adopting the above technical solution, when the sliding core 41 slides to the left, the first variable volume space 402 becomes larger and generates negative pressure, the first one-way valve opens, and the second one-way valve closes, so that the cleaning liquid in the liquid storage box 3 is drawn into the first variable volume space 402 through the first inlet 400; then the sliding core 41 slides to the right, the first variable volume space 402 becomes smaller, the first one-way valve is closed, and the second one-way valve is opened, and the cleaning liquid in the first variable volume space 402 enters the liquid delivery chamber 410; when the sliding core 41 slides to the left again, the second variable volume space 403 becomes smaller, so that the cleaning liquid in the liquid delivery chamber 410 is delivered to the atomizing sheet 5 through the second outlet 413, the first outlet 401, and the conduit 7; the overall volume is small, the space occupied is also small, the structure is simple, and the cleaning liquid can be effectively delivered.

[0096] In an embodiment of the present invention, the sliding core driving mechanism comprises:

[0097] A first rack 43;

[0098] A second rack 44;

[0099] A gear 45, wherein teeth are provided on an outer wall of the gear 45 which is less than half of its circumference;

[0100] A micro motor 46, wherein the micro motor 46 drives the gear 45 to rotate;

[0101] Among them, the first rack 43 and the second rack 44 are respectively arranged on the opposite sides of the driving cavity 411, the gear 45 is arranged between the first rack 43 and the second rack 44 and is meshed and connected, and the gear 45 can only be meshed and connected with the first rack 43 or the second rack 44 alone. The micro motor 46 is installed outside the pump body 40, and its output shaft passes through the pump body 40 and the sliding core 41 in turn and extends into the driving cavity 411. The sliding core 41 is provided with a long strip opening for the output shaft of the micro motor 46 to slide.

[0102] By adopting the above technical solution, the position of the gear 45 relative to the pump body 40 does not change, and the micro motor 46 drives the gear 45 to rotate counterclockwise. When the gear 45 engages with the first rack 43, it can effectively drive the sliding core 41 to slide to the left. As the gear 45 rotates, it separates from the first rack 43 and then engages with the second rack 44, thereby driving the sliding core 41 to slide to the right, thereby effectively driving the sliding core 41 to slide back and forth left and right in the pump body 40. The gear meshing can effectively reduce the noise during operation and extend the service life.

[0103] In an embodiment of the present invention, the first one-way valve and the second one-way valve have the same structure, and the first one-way valve includes:

[0104] A sealing ball 47, wherein a cross bar 48 is connected to the sealing ball 47 along the diameter direction thereof;

[0105] A limiting sleeve 49, wherein the inner wall of the limiting sleeve 49 is provided with grooves 490 corresponding to the two ends of the cross bar 48;

[0106] The middle parts of the first inlet 400 and the second inlet 412 are protruding inward, the minimum inner diameters of the first inlet 400 and the second inlet 412 are smaller than the diameter of the sealing ball 47, the two ends of the cross bar 48 extend into the corresponding grooves 490, and the length of the cross bar 48 is smaller than the distance between the bottoms of the two grooves 490 and larger than the inner diameter of the limit sleeve 49.

[0107] By adopting the above technical solution, when the medium flows from right to left, the sealing ball 47 will move to the left. Under the action of the cross bar 48, the sealing ball 47 can only move within a certain space, thereby effectively limiting the movement range of the sealing ball 47 and ensuring the action response speed of the sealing ball 47.

[0108] In the embodiment of the present invention, the swing cleaning mechanism 6 comprises:

[0109] A shell 60, which is cylindrical, with a coil 61 wound around the outer wall of the shell 60, and the shell 60 is fixed in the housing 1;

[0110] A rotating bracket 62, wherein a magnetic block 63 matching with the coil 61 is installed in the rotating bracket 62, a rotating shaft 620 is protruded on both sides of the rotating bracket 62, and a rotating groove 600 matching with the rotating shaft 620 is provided on the inner wall of the housing 60;

[0111] A swing lever mechanism 64, one end of which is fixedly connected to the rotating bracket 62, and a cleaning cloth 65 is provided on the outer wall of the swing lever mechanism 64, and the cleaning cloth 65 is in contact with the lens 2;

One end of the first torsion spring 66 is connected to the rotating bracket 62, and the other end is connected to the inner wall of the shell 60.

[0114] By adopting the above technical scheme, when the swing cleaning mechanism 6 is in the initial state, the coil 61 is not energized. Under the action of the first torsion spring 66, the swing rod mechanism 64 is in the extreme downward position. When the coil 61 is energized in the positive direction, the coil 61 generates a positive magnetic field, which acts on the magnetic block 63, thereby driving the rotating bracket 62 to rotate upward in the housing 60 and overcome the force of the first torsion spring 66, driving the swing rod mechanism 64 to scrub the lens 2 upward until it reaches the extreme upward position. Then, the coil 61 is energized in the reverse direction, so that the coil 61 generates a reverse magnetic field, which acts on the magnetic block 63, thereby driving the rotating bracket 62 to rotate downward in the housing 60. The first torsion spring 66 also gives the rotating bracket 62 a force to rotate downward, driving the swing rod mechanism 64 to scrub the lens 2 downward. The direction of the magnetic field is changed by changing the direction of the current in the coil 61, thereby realizing the reciprocating swing of the swing rod mechanism 64 to scrub the lens. The mechanism is simple, the volume is small, and the noise is low.

[0118] Wherein, adjacent support rods 640 are connected via elastic return devices 67 .

[0119] By adopting the above technical solution, the swing rod mechanism 64 can maintain a straight rod state when not affected by external force. When affected by external force, adjacent support rods 640 can be bent through the elastic return device 67, so that the swing rod mechanism 64 can fit the outer circle of the lens 2 as much as possible, so that the surface of the lens 2 can be scrubbed more completely, the scrubbing area is increased, and the cleaning effect is better.

[0120] In the embodiment of the present invention, the elastic return device 67 includes:

[0121] A first mounting plate 670, on which a first limiting rod 6700 protrudes;

[0122] A second mounting plate 671, on which a second limiting rod 6710 protrudes;

[0123] A central shaft 672, one end of which is fixed on the side of the second mounting plate 671 facing the first mounting plate 670, and the other end of which is provided with a blind hole 6720;

[0124] An insert shaft 673, wherein the insert shaft 673 is fixed on a side of the first mounting plate 670 facing the second mounting plate 671 and is rotatably matched with the blind hole 6720;

[0125] A first ferrule 674, wherein two first protrusions 6740 are protruded from the outer side of the first ferrule 674;

[0126] A second ferrule 675, wherein two second protrusions 6750 are protruded from the outer side of the second ferrule 675;

[0127] A second torsion spring 676;

[0128] Among them, the first mounting plate 670 and the second mounting plate 671 are respectively arranged on the opposite ends of the two adjacent support rods 640, the first clamping sleeve 674 and the second clamping sleeve 675 are both sleeved on the outside of the central axis 672, and the first clamping sleeve 674 and the second clamping sleeve 675 are both provided with a torsion spring groove 677 for installing the second torsion spring 676, and the two ends of the second torsion spring 676 are respectively connected to the torsion spring groove 677 in the first clamping sleeve 674 and the second clamping sleeve 675, one of the first protrusions 6740 on the first clamping sleeve 674 and one of the second protrusions 6750 on the second clamping sleeve 675 are clamped on both sides of the first limiting rod 6700, and the other first protrusion 6740 on the first clamping sleeve 674 and the other second protrusion 6750 on the second clamping sleeve 675 are clamped on both sides of the second limiting rod 6710.

[0129] By adopting the above technical solution, when the swing arm mechanism 64 swings downward, when approaching the lower wall of the channel 10, the lower end of the support rod 640 below will contact the inner wall of the channel 10, and the support rod 640 will be subjected to resistance, while the upper support rod 640 continues to swing under the action of the rotating bracket 62, so that the two adjacent support rods 640 will rotate along the axis of the central axis 672. When the lower support rod 640 rotates, the second limiting rod 6710 connected to the second mounting plate 671 pushes one of the second protrusions 6750, so that the second clamping sleeve 675 rotates relative to the first clamping sleeve 674, so that the second torsion spring 676 accumulates force; when the swing arm mechanism 64 reaches the limit position of downward movement, the swing arm mechanism 64 moves upward, and as the upper support rod 640 gradually swings upward, under the action of the second torsion spring 676, the second clamping sleeve 675 returns to its initial position, and the swing arm mechanism 64 maintains a straight rod state. The central axes of the support rods 640 are on the same straight line; when the swing arm mechanism 64 swings upward, the lower end of the support rod 640 below contacts the inner wall of the channel 10, thereby pushing one of the first protrusions 6740 through the second limiting rod 6710, so that the first clamping sleeve 674 rotates relative to the second clamping sleeve 675, and the second torsion spring 676 accumulates force; when the swing arm mechanism 64 swings, the cleaning cloth 65 on the support rod 640 can be as close to the edge of the lens 2 as possible, so that the cleaning area is larger and the action response is faster; the force of the rotating bracket 62 when rotating is greater than the force of the second torsion spring 676 in the elastic return device 67, and at the same time, when the swing cleaning mechanism 6 is in the initial state and the coil 61 is not energized, the force of the first torsion spring 66 is also greater than the force of the second torsion spring 676 in the elastic return device 67, so that when the swing cleaning mechanism 6 is not working in the initial state, each support rod 640 can be as close to the inner wall of the channel 10 as possible.

[0130] In the embodiment of the present invention, the elastic return device 67 further includes:

[0131] A rotating bearing 678, wherein the rotating bearing 678 is disposed between the central shaft 672 and the contact surface between the first mounting plate 670 and the insertion shaft 673;

[0132] The elastic sleeve 679 is sleeved on the outside of the connection between two adjacent support rods 640 , and the elastic sleeve 679 is arranged on the inner side of the cleaning cloth 65 .

[0133] By adopting the above technical solution, the rotating bearing 678 can make the rotation between the central axis 672 and the first mounting plate 670 and the plug-in axis 673 smoother and easier; the elastic sleeve 679 can effectively wrap the elastic return device 67 between adjacent support rods 640, preventing external water and impurities from entering the elastic return device 67, thereby ensuring the service life of the elastic return device 67.

[0134] In an embodiment of the present invention, it also includes:

[0135] An electrostatic generator, the electrostatic generator comprising an anode terminal and a cathode terminal;

[0136] A metal sheet 8, wherein the metal sheet 8 is attached to the inner wall of the channel 10;

[0137] The anode end of the electrostatic generator is connected to the cleaning liquid in the liquid storage box 3 and the metal sheet 8 , and the cathode end of the electrostatic generator is connected to the lens 2 .

[0138] By adopting the above technical solution, the electrostatic generator can make the cleaning liquid, metal sheet 8 and lens 2 in the liquid storage box 3 have static electricity, wherein the cleaning liquid and the metal sheet 8 are positively charged, and the lens 2 is negatively charged. When the positively charged cleaning liquid is atomized and sprayed through the atomizing sheet 5, it will be attracted by the negatively charged lens 2, so the cleaning liquid can be evenly sprayed and covered on the surface of the lens 2. At the same time, the metal sheet 8 on the inner wall of the channel 10 is also positively charged, so the cleaning liquid is not easy to float to the inner wall of the channel 10, so that the effect of spraying the cleaning liquid is better, waste is reduced, and there is no contact or insulation between the metal sheet 8 and the lens 2.

[0139] In an embodiment of the present invention, it also includes:

[0140] A drainage hole 101, wherein the drainage hole 101 is provided below an end of the channel 10 close to the lens 2;

[0141] A sewage box 9, the sewage box 9 is arranged in the housing 1, and a drain port 90 for discharging sewage is provided at the bottom of the sewage box 9;

[0142] The drainage hole 101 is connected to the sewage box 9 .

[0143] By adopting the above technical solution, when the swing rod mechanism 64 scrubs the surface of the lens 2, the sewage on the lens 2 will flow into the sewage box 9 through the drainage hole 101 for collection. When the cleaning is completed, the sewage in the sewage box 9 will be discharged from the light absorber through the drain port 90, which is more convenient to use.

[0144] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
