Description

Technical Field

[0001] The invention relates to the technical field of magnetic induction kettles, and in particular to a magnetic induction kettle capable of improving heating efficiency. Background Art

[0002] In the existing electromagnetic heating kettle market, there are many problems that need to be improved. The bottom plate of traditional electromagnetic heating kettles is mostly made of a single material, such as common stainless steel, which has poor magnetic concentration and magnetic induction effects, low heat transfer efficiency, resulting in long boiling time and high energy consumption. Moreover, the bottom plate of a single material is prone to deformation after long-term heating, affecting the normal use and service life of the kettle.

[0003] The common one-piece inner liner has a complex multi-step stretching process during the manufacturing process, and the yield rate is difficult to control, which not only increases the production cost, but also limits the mass production of the product. At the same time, the one-piece inner liner is not easy to clean, which affects the heating efficiency and hygiene. When the high-temperature water in the inner liner is stored for a long time or used repeatedly, it will cool down rapidly over time. The traditional kettle lacks a covering mechanism, and the insulation effect is poor. Heat is easily lost from the spout through water vapor, affecting the insulation performance of the kettle. It cannot automatically rise and fall according to demand to achieve insulation or exhaust. Therefore, it is necessary to spend more electricity to heat it repeatedly during use. This heating process consumes a lot of energy, which is not conducive to environmental protection, and reheating requires time to wait. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figure 1-15A magnetic induction kettle capable of improving heating efficiency is shown, the magnetic induction kettle comprising an outer shell 1, an inner liner 2, a base, a heat insulating device 3, a shielding mechanism 4 and an auxiliary power supply mechanism, the outer shell 1 is provided with a spout 5, the shielding mechanism 4 is located at the spout 5 of the outer shell 1, the inner liner 2 is installed in the outer shell 1, the heat insulating device 3 and the shielding mechanism 4 are both arranged between the inner liner 2 and the outer shell 1, the inner liner 2 is a split design, the inner liner 2 is composed of a separately produced liner wall 6 and a bottom plate, the bottom plate is a multi-layer composite board 7, the thickness of the multi-layer composite board 7 is controlled between 0.5 and 5.0 mm, the liner wall 6 and the multi-layer composite board 7 are sealed, the auxiliary power supply mechanism is installed in the outer shell 1, a plurality of water outlet holes 8 arranged in a honeycomb shape are provided at the top of the liner wall 6 near the spout 5, a switch mechanism 9 is provided on the outer shell 1, and the switch mechanism 9 is transmission-connected to the shielding mechanism 4.

[0040] The inner liner 2 in the magnetic induction kettle shown in the present invention is a split design, and the bottom plate of the inner liner 2 is composed of a multi-layer composite plate 7. The multi-layer composite plate 7 does not limit the material, and the material is such as stainless steel plus aluminum, stainless steel plus aluminum plus stainless steel, stainless steel plus aluminum plus iron plus aluminum plus stainless steel, stainless steel plus copper plus stainless steel, and stainless steel plus copper plus iron plus copper plus stainless steel, etc. Each layer of material is tightly combined by advanced welding or high-temperature pressing process. One of the methods is described in detail, and other implementation methods are similar to this method. For example, the bottom layer close to the heating source is made of stainless steel with good magnetic conductivity, the middle layer is aluminum with excellent thermal conductivity, and the upper layer in contact with water is made of stainless steel with strong corrosion resistance. The thickness ratio of each layer has been carefully calculated and experimentally verified to achieve the optimal magnetic concentration and thermal conductivity effect, thereby greatly improving the heat transfer efficiency and shortening the water boiling time. The present invention can fill the single bottom plate form of the induction cooker on the market, and has the advantages of shortening the water boiling time, improving the heat transfer efficiency, and reducing the possibility of bottom plate deformation. The split inner liner 2 manufacturing process reduces the complexity of the multi-pass stretching process of the kettle body and the uncontrollable process yield, greatly improves the batch size of the product, and also has great advantages in cost control, and is more flexible than the existing technology. The present invention can shorten the boiling time, improve the heat transfer efficiency, and is not easy to deform. For kettles of the same specifications and sizes, the boiling time can be shortened by about 5 minutes, and the heat transfer efficiency can be improved by more than 30%. The auxiliary power supply mechanism can be charged during the process of boiling water in the magnetic induction kettle, thereby powering the intelligent electronic equipment inside the magnetic induction kettle. There is no need to perform separate operation to power the electronic equipment, which improves the convenience of use.

[0041] After the water in the magnetic induction kettle boils, depending on the user's usage habits and the amount of water in the kettle, the amount of hot water used for the first time only occupies a part of the kettle, which will result in more hot water being stored in the kettle. The hot water stored in the inner tank 2 needs to be kept warm, thereby reducing the temperature when used again, and reducing the initial temperature of the hot water inside the inner tank 2 when heated again, so as to reduce the energy and time required for secondary heating. By providing a heat insulation device 3 between the outer shell 1 and the inner tank 2, the heat insulation effect of the inner tank 2 can be achieved. However, at this time, the heat of the hot water inside the inner tank 2 will be discharged from the water outlet 8 to the spout 5 in the form of water vapor, and finally discharged outward through the spout 5. At this time, the heat will be dissipated quickly, which is not conducive to heat preservation. Therefore, the present invention is provided with a covering mechanism 4 with an intelligent lifting function at the spout 5, which can automatically realize the lifting function according to whether the switch mechanism 9 is opened or not, and can also realize manual opening or closing operations. This arrangement can completely seal the inner tank 2 from the outside when insulation operation is required, preventing the high-temperature water vapor inside from flowing out, thereby achieving a long-term insulation effect. This method can also ensure that the spout 5 is in an open state during the boiling water process, avoiding the situation where the air pressure inside the inner tank 2 is too high and the hot steam cannot be discharged during the boiling water process. After the covering mechanism 4 covers the spout 5, when pouring water is needed, the covering mechanism 4 can be manually opened to facilitate the pouring operation.

[0042] The auxiliary power supply mechanism includes a copper coil, a battery and an electronic temperature display. The copper coil is snap-fitted and installed on the outside of the base plate. The battery and the electronic temperature display are both installed on the handle of the magnetic induction kettle. The battery is arranged inside the handle. The copper coil is electrically connected to the battery, and the battery is electrically connected to the electronic temperature display.

[0043] When the magnetic induction kettle is boiling water, the auxiliary power supply mechanism generates current through electromagnetic induction of the copper coil installed in the shell 1 to charge the battery installed in the handle, and the battery charges electronic equipment such as the electronic temperature display.

[0044] In the first embodiment shown in the present invention:

[0045] The gallbladder wall 6 is made of metal, and the gallbladder wall 6 and the multi-layer composite plate 7 are sealed and connected by welding. The heat insulation device 3 is a heat insulation filling material.

[0046] In the first embodiment of the present invention, the gallbladder wall 6 and the multi-layer composite plate 7 are both made of metal materials, but are produced in a separate manner, which reduces the complexity of the multi-step stretching process of the pot body and the uncontrollable process yield, greatly improves the batch production of the product, and the metal gallbladder wall 6, such as stainless steel, is cheap, has high stability and safety, is highly practical, and has a long service life.

[0047] There are multiple welding methods for the liner wall 6 and the liner 2. First, the connection method between the liner 2 and the multi-layer composite plate 7 can be laser welding technology, so that the two metal materials can be seamlessly welded, and the surface is brushed to meet the integrated effect of the liner 2. Second, the liner 2 and the multi-layer composite plate 7 can also use brazing technology to make the multi-layer composite plate 7 and the liner 2 material more effectively combined, further improving the heat conduction efficiency.

[0048] The outer wall of the inner liner 2 is closely fitted with the heat insulation material, which improves the heat preservation effect and reduces heat dissipation. The filling material is reasonably priced and has a better heat preservation effect.

[0049] In the second embodiment shown in the present invention:

[0050] The gallbladder wall 6 is made of glass and is sealed to the multi-layer composite board 7. A rubber sealing ring 10 is provided at the connection between the outer wall of the gallbladder wall 6 and the multi-layer composite board 7. An annular heat insulating material 11 is fixed at the connection between the multi-layer composite board 7 and the gallbladder wall 6.

[0051] In the second embodiment, the wall 6 of the pot is made of glass, and the glass can be high temperature resistant borosilicate glass. The annular heat insulating material 11 is made of high temperature resistant ceramic fiber material, which has good heat insulation performance and certain mechanical strength. This design can effectively prevent the glass from breaking due to overheating. The rubber sealing ring 10 is used to ensure the sealing connection effect between the wall 6 and the multilayer composite plate 7 to prevent water leakage. The glass material can intuitively observe the liquid level and state of the water in the pot. At the same time, it is not easy to leave scale on the glass surface, which is easy to clean and improves practicality.

[0052] The heat insulating device 3 is a vacuum double-layer partition tube, and the materials of the vacuum double-layer partition tube and the outer shell 1 are both transparent or translucent materials.

[0053] The transparent or translucent shell 1 is made of a high temperature resistant plastic material, such as polycarbonate, and is manufactured by injection molding. Its surface can be frosted or polished to achieve an aesthetic and practical effect. The vacuum double-layer partition cylinder can be made of double-layer insulation glass, the interior of which is vacuumized to improve the insulation efficiency while having a certain degree of light transmittance. This design can intuitively observe the liquid level and state of the water in the pot, thereby improving the aesthetics and practicality.

[0054] The shielding mechanism 4 includes a shielding component, a transmission component and a jacking component. The shielding component includes a lifting baffle 12 vertically lifted and arranged on the shell 1 and a fixing frame 13 fixedly installed on the shell 1. A sliding groove 14 is arranged in the fixing frame 13. The lifting baffle 12 is slidably connected with the fixing frame 13 through the sliding groove 14. A rubber top plate 15 is arranged on the top of the lifting baffle 12. A sealing plate 16 is arranged at the bottom of the lifting baffle 12. The sealing plate 16 is tightly fitted with the sliding groove 14. A resisting card strip 17 for resisting with the rubber top plate 15 is also installed on the top of the shell 1. An exhaust hole 18 is opened on the side wall of the lifting baffle 12. A plurality of elastic rubber sheets distributed in an annular manner around the axis direction of the exhaust hole 18 are arranged in the exhaust hole 18. Vertical slide rails 19 are arranged on both sides of the lifting baffle 12. The jacking component is arranged directly below the lifting baffle 12. The jacking component is transmission-connected to the lifting baffle 12. The switch mechanism 9 is transmission-connected to the transmission component. The transmission component is transmission-connected to the jacking component.

[0055] When performing the covering operation, the spout 5 can be covered by the lifting baffle 12 in the covering assembly, so that the hot air inside the inner pot 2 cannot be discharged, and the dissipation time of the internal heat is increased as long as possible, thereby improving the efficiency of secondary heating and reducing the heating time.

[0056] When the switch mechanism 9 is turned on (i.e., the switch is turned on and the water is boiled), the switch mechanism 9 drives the lifting assembly to work through the transmission assembly, and the lifting assembly drives the cover assembly to move downward, opening the spout 5, so as to realize the exhaust function during the water boiling process and prevent the internal air pressure of the liner 2 from being too high and causing safety hazards. After the water boiling operation is completed, the switch mechanism 9 is automatically closed. At this time, the switch mechanism 9 drives the lifting assembly to move through the transmission assembly, so that the lifting baffle 12 in the cover assembly connected to it is driven to rise through the lifting baffle 12, and the spout 5 is sealed and shielded by the lifting baffle 12. This process is automatic, and the cover operation is automatically realized after the water boiling is completed, so as to save as much internal heat as possible. When pouring water, the lifting baffle 12 in the cover assembly can be manually pressed downward. The lifting assembly has a certain elastic stroke, and the lifting baffle 12 can be pressed down when the switch mechanism 9 remains unchanged, so that it can be lowered to leak out the spout 5, which is convenient for normal water pouring. During secondary heating, the switch mechanism 9 is opened, the lifting assembly automatically rebounds and resets, and the switch mechanism 9 can still drive the lifting baffle 12 to descend normally.

[0057] The fixing frame 13 is used to install the lifting baffle 12. The lifting baffle 12 is slidably connected to the fixing frame 13 through the sliding groove 14. The rubber top plate 15 on the top of the lifting baffle 12 can cooperate with the abutting card strip 17 to achieve a sealing effect, ensuring that the gas will not be easily discharged outward when the mouth is covered. The exhaust hole 18 is set to prevent the internal air pressure of the inner tank 2 from being too high and the gas cannot be discharged when exhaust is required. The exhaust hole 18 is set to ensure the safe use of the equipment and prevent the lifting baffle 12 from failing to descend as scheduled due to mechanical failure or other reasons, resulting in the mouth being covered when boiling water. It is ensured that the air can still be exhausted normally at this time, and safety incidents such as explosion of the pot will not occur. When the sealing plate 16 set at the bottom of the lifting baffle 12 cooperates with the fixing frame 13, it can play a sealing effect to prevent water from leaking downward from the connection between the lifting baffle 12 and the fixing frame 13. The vertical slide rail 19 is used to guide and limit the lifting and lowering of the lifting baffle 12.

[0058] It is worth mentioning that the use of the lifting baffle 12 can realize the autonomous operation of the covering operation and the automatic opening operation when boiling water, improve the effect of automatic heat preservation, and can also drive the lifting baffle 12 to automatically rise when the pressing plate 38 automatically pops up after the boiling water is completed. During this process, no additional operation is required by the operator.

[0059] The transmission assembly includes a first connecting rod 20, an arc-shaped transmission rod 21, an arc-shaped mounting groove 22 and a second connecting rod 23. The arc-shaped mounting groove 22 is fixedly installed at the bottom of the shell 1, and the arc-shaped transmission rod 21 is slidably set in the arc-shaped mounting groove 22. One end of the first connecting rod 20 is transmission-connected to the switch mechanism 9, and the other end of the first connecting rod 20 is hinged to one end of the arc-shaped transmission rod 21 away from the jacking assembly. One end of the second connecting rod 23 is hinged to one end of the arc-shaped transmission rod 21 away from the first connecting rod 20, and the other end of the second connecting rod 23 is transmission-connected to the jacking assembly.

[0060] When the transmission assembly is working, the switch mechanism 9 drives the first connecting rod 20 to move. When the first connecting rod 20 moves, it drives the arc-shaped transmission rod 21 hinged thereto to slide in the arc-shaped mounting groove 22. The arc-shaped transmission rod 21 pulls the second connecting rod 23, driving the second connecting rod 23 to move. The second connecting rod 23 drives the lifting assembly that is transmitted thereto to work, thereby realizing the transmission function between the switch mechanism 9 and the lifting assembly.

[0061] The lifting assembly includes a metal telescopic rod 24, a first limit frame 25 and a compression locking device. The first limit frame 25 is vertically fixedly installed directly below the lifting baffle 12. The first limit frame 25 is provided with a first vertical slide groove 26 and a second vertical slide groove 27. The metal telescopic rod 24 is vertically slidably set on the first limit frame 25 through the first vertical slide groove 26. The end of the second connecting rod 23 away from the arc-shaped transmission rod 21 passes through the second vertical sliding groove 14 and is hinged to the bottom end of the metal telescopic rod 24. The top end of the metal telescopic rod 24 is fixedly connected to the lifting baffle 12, and the compression locking device is set on the metal telescopic rod 24.

[0062] The metal telescopic rod 24 is lifted and slid in the shell 1 through the first limit frame 25. The first vertical slide groove 26 on the first limit frame 25 is used to guide and limit the metal telescopic rod 24. The second vertical slide groove 27 is used to avoid the second connecting rod 23 to facilitate the connection position of the second connecting rod 23 and the metal telescopic rod 24. The compression locking device is used to realize the telescopic function of the metal telescopic rod 24, so as to realize the compression function of the jacking assembly.

[0063] The compression locking device includes a transmission ring 28, a first spring 29, a first metal elastic buckle 30, a first slot 31, a locking slot 32, a first electromagnet 33, a transmission column 34 and a third vertical slide groove 35. The metal telescopic rod 24 is composed of a metal plug rod and a metal sleeve. The third vertical slide groove 35 is vertically arranged on the outer side wall of the shell 1. The transmission column 34 is horizontally arranged. One end of the transmission column 34 is fixedly connected to the top of the metal plug rod, and the other end of the transmission column 34 is arranged outward through the third vertical slide groove 35. The transmission ring 28 is fixedly installed on the top of the metal plug rod. The first metal The metal elastic buckle 30 is fixedly installed at the bottom of the transmission ring 28, the first card slot 31 is set at the bottom of the metal sleeve, and the first metal elastic buckle 30 and the first card slot 31 are clamped when the transmission ring 28 is at the bottom. The first electromagnet 33 is fixedly installed on the bottom of the metal telescopic rod 24 away from the side of the card slot, and the locking card slot 32 is set at the top of the metal sleeve. The first metal elastic buckle 30 and the locking card slot 32 are clamped when the transmission ring 28 is at the top. A touch button 36 electrically connected to the first electromagnet 33 is provided on the end of the transmission column 34 away from the metal telescopic rod 24.

[0064] In the initial state, the locking slot 32 is engaged with the first metal elastic buckle 30 , and the metal telescopic rod 24 is in a locked state, that is, the metal plug rod and the metal sleeve do not slide relative to each other. At this time, the lifting assembly can drive the lifting baffle 12 to move synchronously through the metal telescopic rod 24 . When the compression assembly needs to work, the operator pulls the transmission column 34 to drive the metal plug rod fixedly connected thereto to move up and down, and the operator unlocks the first metal elastic buckle 30 and the locking slot 32 by pressing the driving force downward. After unlocking, the metal plug rod is driven to be inserted into the metal sleeve. After pressing down to the right position, the first metal elastic buckle 30 installed on the metal plug rod is engaged with the first slot 31. At this time, when the switch mechanism 9 is in the closed state, the pressing operation can still be performed, which is convenient for the user to pour water. After pouring water, the first electromagnet 33 can be controlled by the touch button 36 to generate suction, and the first metal elastic buckle 30 is offset to the side close to the first electromagnet 33, so that the first metal elastic buckle 30 is separated from the first slot 31, and the metal telescopic rod 24 is reset under the elastic force of the first spring 29, and the lifting baffle 12 is pushed upward again. When secondary heating is required, the first electromagnet 33 will also be controlled to generate suction during heating, so that the metal telescopic rod 24 is reset, which is convenient for subsequent operations.

[0065] The switch mechanism 9 includes a ball shaft 37, a pressing plate 38, a second electromagnet 39, a second metal elastic buckle 40, a second spring 41 and a second slot 42. The ball shaft 37 is installed on the housing 1. The middle part of the pressing plate 38 is axially connected to the housing 1 through the ball shaft 37. One end of the pressing plate 38 inside the housing 1 is hinged to the first connecting rod 20. The second electromagnet 39 is fixedly installed on the bottom of the housing 1. The second metal elastic buckle 40 is fixedly installed on the pressing plate 38. The second slot 42 is fixedly set on the housing 1. The second metal elastic buckle 40 is clamped with the second slot 42. The second electromagnet 39 is located on the side of the second metal elastic buckle 40 away from the second slot 42. One end of the second spring 41 is fixedly connected to the bottom of the housing 1, and the other end of the second spring 41 is fixedly connected to the end of the pressing plate 38. A switch contact is provided at the end of the pressing plate 38.

[0066] When the switch mechanism 9 is working, the operator operates the pressing plate 38, so that the pressing plate 38 is deflected on the housing 1 through the ball shaft 37. At this time, the second metal elastic buckle 40 is engaged with the second slot 42 to realize the locking function. At this time, the switch contacts of the pressing plate 38 are in contact, and the power is turned on to start the water boiling operation. The pressing plate 38 drives the first connecting rod 20 hinged thereto to deflect, and drives the transmission assembly to move through the first connecting rod 20 to realize the transmission function. After the water boiling operation is completed, the second electromagnet 39 is energized to generate suction, and the second metal elastic buckle 40 is sucked outward, so that the second metal elastic buckle 40 is released from the second slot 42, and the pressing plate 38 is reset under the elastic force of the second spring 41.

[0067] The top of the lifting baffle plate 12 is set to be V-shaped and matches the shape of the bottom end of the spout 5, and the abutment strip 17 and the rubber top plate 15 both match the shape of the lifting top plate.

[0068] In order to prevent a certain amount of water from being stored between the rubber top plate 15 on the top of the lifting baffle 12 and the outer shell 1 during the pouring process, the lifting baffle 12 and the matching interference strip 17 and the rubber top plate 15 are all set to be V-shaped, so that water will not accumulate between the outer shell 1 and the rubber top plate 15 during the pouring process, and can easily flow back downward to the inside of the kettle, which is easy to use.

[0069] Working principle of the present invention:

[0070] When the switch mechanism 9 is turned on (i.e., the switch is turned on and the water is boiled), the first connecting rod 20 is driven to move by the switch mechanism 9. When the first connecting rod 20 moves, the arc-shaped transmission rod 21 hinged thereto is driven to slide in the arc-shaped mounting groove 22. The arc-shaped transmission rod 21 pulls the second connecting rod 23, drives the second connecting rod 23 to move, and drives the jacking assembly driven thereto to work through the second connecting rod 23, thereby realizing the transmission function between the switch mechanism 9 and the jacking assembly. The rubber top plate 15 on the top of the lifting baffle 12 can cooperate with the resisting card strip 17 to achieve a sealing effect, ensuring that the gas will not be easily discharged outward when the mouth is covered, and the setting of the exhaust hole 18 is to prevent the gas from being discharged when the internal air pressure of the inner tank 2 is too high and the gas cannot be discharged when exhaust is required. The exhaust hole 18 is set to ensure the safe use of the equipment, and prevent the lifting baffle 12 from failing to descend as scheduled due to mechanical failure or other reasons, resulting in the mouth being still in the covering state when boiling water, ensuring that the air can still be exhausted normally at this time, and will not cause safety incidents such as explosion of the pot. The metal telescopic rod 24 is lifted and slid in the shell 1 through the first limit frame 25. The first vertical slide groove 26 on the first limit frame 25 is used to guide and limit the metal telescopic rod 24. The second vertical slide groove 27 is used to avoid the second connecting rod 23 to facilitate the connection position of the second connecting rod 23 and the metal telescopic rod 24. The compression locking device is used to realize the telescopic function of the metal telescopic rod 24, so as to realize the compression function of the jacking assembly.

[0071] The locking slot 32 is engaged with the first metal elastic buckle 30. At this time, the metal telescopic rod 24 is in a locked state, that is, the metal plug rod and the metal sleeve do not slide relative to each other. At this time, the lifting assembly can drive the lifting baffle 12 to move synchronously through the metal telescopic rod 24. The lifting assembly drives the cover assembly to move downward, opening the spout 5, which is convenient for realizing the exhaust function during the boiling water process and preventing the internal air pressure of the liner 2 from being too high and causing safety hazards. After the boiling water operation is completed, the switch mechanism 9 is automatically closed. At this time, the switch mechanism 9 drives the lifting assembly to move through the transmission assembly, thereby driving the lifting baffle 12 in the cover assembly connected to it to rise through the lifting assembly, and the spout 5 is sealed and shielded by the lifting baffle 12. This process is automatic. After the boiling water is completed, the cover operation is automatically realized to preserve as much internal heat as possible. When it is necessary to pour water, the operator drives the metal plug rod fixedly connected thereto to rise and fall by pulling the transmission column 34, and the operator unlocks the first metal elastic buckle 30 and the locking slot 32 by pressing down the driving force. After unlocking, the metal plug rod is driven to be inserted into the metal sleeve. After pressing down into place, the first metal elastic buckle 30 installed on the metal plug rod is engaged with the first slot 31. At this time, when the switch mechanism 9 is in the closed state, the downward pressing operation can still be performed, which is convenient for the user to perform the water pouring operation, so that the lifting baffle 12 can be lowered to leak out the spout 5, which is convenient for normal water pouring. After pouring the water, the first electromagnet 33 can be controlled by the touch button 36 to generate suction, and the first metal elastic buckle 30 is offset to the side close to the first electromagnet 33, so that the first metal elastic buckle 30 is separated from the first slot 31, and the metal telescopic rod 24 is reset under the elastic force of the first spring 29, and the lifting baffle 12 is pushed upward again. When secondary heating is required, the first electromagnet 33 will be controlled to generate suction during heating, so that the metal telescopic rod 24 is reset, the lifting assembly automatically rebounds and resets, and the switch mechanism 9 can still drive the lifting baffle 12 to descend normally.

[0072] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
