Description

Technical Field

[0001] The utility model relates to the field of dehumidification devices, in particular to a one-way demisting device for actively electrolyzing water molecules with one-way accelerated exhaust. Background Art

[0002] Smart helmet displays, headlights, monitoring probes, image detection, laser radar detection sensors, marine equipment cabinets and other products and equipment with sealed housings containing electronic components will have internal temperatures that rise when in operation and decrease when stopped. When the temperature and humidity change outside (such as fog, rain and other weather), the humidity and air pressure inside the sealed housing products and equipment with electronic components will rise due to the changes in temperature and humidity inside and outside the housing, and their transparent masks or lenses may even fog, condense water and expand and deform the housing. This phenomenon can cause insulation failure and short circuit of electronic components, and in severe cases, fire, explosion and other dangerous situations, which will bring immeasurable serious consequences to operators or people close to sealed housings and equipment with electronic components, such as image signal distortion and misjudgment, unclear driving lighting, and safety of life and property.

[0003] At present, in order to solve this problem, various fields in China usually use desiccant or heating fans to dehumidify and reduce the internal moisture humidity. Since the desiccant has a low moisture absorption rate and is not waterproof and has a short lifespan, it needs to be dried regularly before use. If it encounters water, it needs to be replaced with a new desiccant; the heating fan consumes high current, needs waterproof treatment and has a certain amount of noise; it is difficult to meet the requirements of engineering applications.

[0004] At present, electrolytic components that use the principle of water electrolysis will cause excessive oxygen concentration inside smart helmet displays, car lights, monitoring probes, image detection, lidar detection sensors, etc. The oxygen atoms or molecules released by electrolysis will cause rust and poor contact of the internal electrical components and circuits (internal chips, integrated blocks and other electronic components, lines, PI insulation layers, etc.) in an oxygen-rich environment. Continuous electrolysis will cause excessive accumulation of internal oxygen concentration, resulting in the risk of spontaneous combustion; hydrogen accumulation on the cathode side will pose a risk of hydrogen explosion; and frequent electrical failures make it difficult to meet the user's reliability requirements.

[0026] See also Figure 1, an active electrolytic water molecule unidirectional demisting device with unidirectional accelerated exhaust, comprising a base 20 mounted on an external device 19. A plurality of connecting buckles 21 are arranged at intervals in the circumferential direction of the base 20. The entire device is mounted on the external device 19 through the connecting buckles 21. The external device 19 can be a sealed device with electronic components such as an intelligent helmet display, a car light, a monitoring probe, an image detection, a laser radar detection sensor, and an electric cabinet of marine equipment.

[0027] The base 20 is provided with an installation cavity and an exhaust channel 24 for the internal gas of the device to flow out. The installation cavity and the exhaust channel are isolated from each other. An ePTFE microporous dustproof breathable membrane 25 is provided on the air inlet side of the exhaust channel 24, and a silicone valve sheet 26 is provided on the exhaust side of the exhaust channel 24. The base 20 is provided with a porous cover plate 23 on the air inlet side of the exhaust channel 24, and a plurality of vents are provided on the porous cover plate 23. The porous cover plate 23 is located on the right side of the ePTFE microporous dustproof breathable membrane 25. The base 20 is provided with an ePTFE waterproof, dustproof and breathable film patch 27 on the air outlet side of the exhaust channel 24, and the ePTFE waterproof, dustproof and breathable film patch 27 is located on the left side of the silicone valve sheet 26. When the temperature inside the device increases, the internal air pressure increases. Under the action of the pressure difference, the cross-shaped silicone valve plate 26 opens, and the hot and humid gas inside the device enters the exhaust channel 24 through the porous cover plate 23 and the ePTFE microporous dust-proof and breathable membrane 25, flows along the exhaust channel 24 to the cross-shaped silicone valve plate 26, and is finally discharged from the ePTFE waterproof, dust-proof and breathable film patch 27, which can quickly discharge the hot and humid air inside the device, thereby reducing the humidity inside the device.

[0028] The base 20 is also provided with a desiccant bag 22, which is located on the left side of the ePTFE microporous dustproof breathable membrane 25. The desiccant bag 22 is a common desiccant bag or a reversible moisture absorption desiccant bag. The desiccant bag can absorb the humid air in the device, and the desiccant bag is independently arranged between the exhaust channel 24 and the installation cavity.

[0029] The desiccant bag 22 is a common desiccant bag or a reversible hygroscopic desiccant bag. The reversible hygroscopic desiccant bag is a mixture of hygroscopic particulate matter and micropowder particles of a substance that efficiently absorbs far-infrared radiation energy. The reversible hygroscopic particulate matter is one or more of a reversible desiccant, bentonite, silica aerogel, carbon molecular sieve, carbon aerogel adsorbent and water-absorbent resin; the micropowder particles of a substance that efficiently absorbs far-infrared radiation energy sensitive include one or more of carbon element products, biochar, tourmaline, far-infrared ceramics, zirconium carbide, metal oxides and silicon carbide. The substance that efficiently absorbs far-infrared radiation energy sensitive provides energy for drying the hygroscopic reversible hygroscopic particulate matter to remove micro-water, so that the mixture of hygroscopic particulate matter and micropowder particles of a substance that efficiently absorbs far-infrared radiation energy can restore the hygroscopic drying capacity. Common desiccants include magnesium chloride desiccant, silica gel material desiccant, calcium chloride desiccant, mineral desiccant, montmorillonite powder desiccant, quicklime powder desiccant, biochemical desiccant, carbon molecular sieve desiccant, chemical fiber desiccant, column desiccant, shipping container desiccant strips, etc.

[0030] A one-way oxygen exhaust and dehumidification device is provided in the installation cavity. The one-way oxygen exhaust and dehumidification device comprises a shell 1 having an air flow channel, a membrane electrode assembly 5 is provided in the shell 1, and the membrane electrode assembly 5 divides the air flow channel into an air inlet end 17 and an air outlet end 18. The anode side of the membrane electrode assembly 5 faces the air inlet end 17, and the cathode side of the membrane electrode assembly 5 faces the air outlet end. An oxygen exhaust channel 16 is provided on the shell 1 to connect the air inlet end 17 with the outside, and oxygen in the reaction process is discharged from the oxygen exhaust channel 16.

[0031] The air inlet end 17 is provided with a coating membrane 14 that is continuously unidirectionally permeable, and the air outlet end 18 is provided with an ePTFE microporous breathable protective membrane 6. The ePTFE microporous breathable protective membrane 6 forms a filtering breathable protective layer on the one hand, which discharges the hydrogen produced by cathode electrolysis and the water molecule gas synthesized with oxygen in the atmosphere under the action of the catalyst; on the other hand, it prevents rainwater, dust, oil and other pollutants in the external environment from entering the cathode cavity, protects the cathode and catalyst layer from the risk of external environmental pollution, and prolongs the life of the electrolysis device, effectively exerting the efficiency of electrolytic dehumidification.

[0032] The continuous one-way moisture-permeable coating film 14 adopts a polyurethane emulsion coating agent (see patent CN103862728B for details). The polyurethane molecular structure contains a high molecular compound containing -NHCOO- units. Its main principle is to introduce an appropriate amount of hydrophilic groups on the polymer chain, which spontaneously disperses under certain conditions to form an emulsion. The PU macromolecule contains a large number of polar groups and has a strong intermolecular force, resulting in excellent film-forming properties. It can form a tough and durable film on the fabric, and it also has certain moisture permeability. The reason is: on the one hand, the polar groups or hydrophilic groups in PU, such as -OH, -NHCOO-, -COOH, silicone powder, etc., act as "chemical stepping stones" to make water vapor molecules migrate from the high humidity side to the low humidity side along the ladder; theoretically, there are mainly hydrophilic groups on the polymer chain, and as long as the content and arrangement of the hydrophilic groups are appropriate, they can interact with water molecules, and with the help of hydrogen bonds and other intermolecular forces, after adsorbing water on the high humidity side, it is transferred to the low humidity side for desorption through the hydrophilic groups on the polymer chain. Therefore, moisture permeability is essentially a process of "adsorption-diffusion-transfer-desorption". The hydrophilic group is called a "chemical stepping stone". In the presence of a pressure difference, moisture is transferred from one side to the other in a directional manner. This process is also a unidirectional moisture permeability process.

[0033] The continuous one-way moisture-permeable coating film 14 is obtained by rolling a polyurethane emulsion coating agent containing hydrophilic groups on the surface of one side of the expanded polytetrafluoroethylene membrane, drying the coating at a temperature of 80°C to 100°C, and storing it at room temperature for 24 hours. The coating is solidified on the surface of the expanded polytetrafluoroethylene membrane to form a dense and durable coating. The coating contains hydrophilic groups and interacts with water molecules. With the help of hydrogen bonds and other intermolecular forces, it absorbs moisture on the high-humidity side and then transfers it to the low-humidity side for desorption through the hydrophilic groups on the polymer chain. Therefore, moisture permeability is essentially a process of "adsorbing" water vapor molecules on the surface of the hydrophilic group polyurethane coating - water molecules "diffuse" from the inside of the hydrophilic group polyurethane coating to the outside - water molecules "desorb" on the interface between the hydrophilic group polyurethane coating and the expanded polytetrafluoroethylene membrane - water molecules enter the dense micropores of the expanded polytetrafluoroethylene membrane and discharge moisture to the external environment. The hydrophilic group is called a "chemical stepping stone". In the presence of a pressure difference, micro-water is transferred directionally from the side with high concentration to the other side with low humidity. This process is also called a one-way moisture permeability process.

[0034] A large number of tests on the coating film 14 with continuous unidirectional moisture permeability have found that the moisture permeability of water vapor discharged from the coating side to the expanded polytetrafluoroethylene membrane side is greater than the moisture permeability of water vapor discharged from the expanded polytetrafluoroethylene membrane side to the coating side. The difference in the two moisture permeability directions leads to the difference in moisture permeability. The moisture permeability from the coating side to the outside is about 30% greater than the moisture permeability from the expanded polytetrafluoroethylene membrane side to the shell 1. By utilizing the huge difference in moisture permeability in these two directions, this coating film is applied to electrical (automotive light) electronic equipment, the coating side of this coating film faces the automotive electrical (automotive light) electronic equipment, and the expanded polytetrafluoroethylene membrane of this coating film faces the external atmosphere; in this way, the water vapor in the shell of the electrical (automotive light) electronic equipment is continuously discharged, showing the characteristic of unidirectional continuous discharge of water vapor from the shell 1 to the external environment. When the electrical (automotive light) electronic equipment is working, when the temperature in the shell 1 is high, the more active the hydrophilic polymer chain segment of the coating is, the faster the speed of adsorption, diffusion and desorption of water vapor molecules is.

[0035] The continuous one-way moisture permeable coating membrane 14 has the function of one-way moisture permeability and airtightness. The function of the continuous one-way moisture permeable coating membrane 14 is that the anode electrolysis chamber is separated by the continuous one-way moisture permeable coating membrane 14 into a chamber connected to the external atmospheric environment. The water molecules in the separated anode chamber are electrolyzed under the action of the platinum-carbon catalyst on the anode side to release oxygen atoms or molecules, hydrogen protons and electrons; the oxygen atoms or molecules released by electrolysis are continuously released to the external atmospheric environment through small channels. The separated anode chamber presents a micro-positive pressure dry environment with very low humidity under the action of the electrolysis function. The water molecules in the hot and humid air inside the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc. migrate to the anode chamber through the one-way moisture permeable coating membrane, permeate, diffuse and desorb to the anode chamber to be electrolyzed. (Moisture permeability is essentially a process of "adsorption-diffusion-transfer-desorption". The hydrophilic group is called a "chemical stepping stone". In the presence of a pressure difference, the micro-water content is directed from the high-concentration side to the wet side. The moisture content in the air inside the device is also continuously reduced under the action of the electrolysis device, and the humidity value continues to decrease, and the inside of the device remains in a dry state. Even if the dew point of the external environment is very low, the smooth mirror surface of the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. will not be fogged or condensed. This is an important new major innovation of the device, which prevents the electronic components, circuits, PI insulation layers, etc. inside the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. from being corroded by oxygen-rich environments, and their electrical performance is more reliable, with lower failure rates and longer service life.

[0036] The outer side of the shell has an external thread for installing the membrane electrode assembly 5 and connecting to equipment such as smart helmet displays, car lights, monitoring probes, image detection, and lidar detection sensors. A through-hole cover plate 4 is provided on the exhaust end 18, and the through-hole cover plate 4 and the shell bracket can be fixed by welding or gluing. The ePTFE microporous breathable protective membrane 6 is arranged on the end face of the cover plate. A PET protective layer 7 with through holes is also bonded to the outside of the ePTFE microporous breathable protective membrane 6, and the two brackets can be connected by an adhesive. The PET protective layer 7 with through holes can increase the strength of the ePTFE microporous breathable protective membrane 6.

[0037] The elastic sealing ring 3 compresses the membrane electrode assembly 5, so that the conductivity of the electrolysis circuit of the device is better. The membrane electrode assembly 5 includes a conductive carbon paper diffusion layer 8, a cathode catalyst layer 9, a proton exchange membrane 10, an anode catalyst layer 11 and an anode porous foil net 12 arranged in sequence. The cathode catalyst layer 9 is a cathode platinum carbon Pt / C catalyst layer, the proton exchange membrane 10 is a perfluorosulfonic acid proton exchange membrane or a perfluorosulfonic acid proton exchange membrane reinforced with an ePTFE microporous membrane, the anode catalyst layer 11 is an anode platinum carbon Pt / C catalyst layer, and the anode porous foil net 12 is an anode platinum titanium Pt / Ti porous foil net. A DC anode conductor 15 and a DC cathode conductor 13 are also provided in the shell, the DC anode conductor 15 is connected to the anode platinum titanium Pt / Ti porous foil net, the DC cathode conductor 13 is connected to the conductive carbon paper diffusion layer 8, and the DC anode conductor 15 and the DC cathode conductor 13 form a conductive electrolysis reaction loop.

[0038] The conductive carbon paper diffusion layer 8 is an electrolytic circuit conductor having microporous through holes, through which hydrogen produced by cathode electrolysis and water molecule gas synthesized with oxygen in the atmosphere under the action of a catalyst are diffused and discharged.

[0039] The cathode platinum carbon Pt / C catalyst layer is the cathode side catalyst layer. The H produced by electrolysis under the action of the anode side platinum carbon catalyst + Under the action of DC voltage, H+ flows through the perfluorosulfonic acid proton exchange membrane or the perfluorosulfonic acid proton exchange membrane reinforced with ePTFE microporous membrane to reach the cathode side. Under the action of the platinum-carbon catalyst on the cathode side, the H+ reacts as follows to generate hydrogen molecules or water molecules:

[0040] 4H + +4e—2H2, O2+4H + +4e - —2H2O; H + Under the action of the platinum-carbon catalyst on the cathode side, the following reaction is formed to generate hydrogen molecules or water molecules, which are released into the atmosphere of the external environment through the ePTFE microporous membrane and the external atmospheric convection of the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc., making the hydrogen concentration on the cathode side extremely low and in a safe state.

[0041] Perfluorosulfonic acid proton exchange membrane or perfluorosulfonic acid proton exchange membrane reinforced with ePTFE microporous membrane is H + Under the action of the electric field force formed by the voltage between the anode and the cathode, H + Conducted to the cathode side, this proton exchange membrane 10 only allows H + By blocking the passage of electrons, electrons flow through the DC power supply through the conductor circuit, forming a closed conductive system loop.

[0042] The perfluorosulfonic acid proton exchange membrane or the perfluorosulfonic acid proton exchange membrane reinforced with the ePTFE microporous membrane electrolyzes the water molecules in the internal space of the intelligent helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc. to reduce the internal humidity. Even under very low dew point conditions, no fogging and condensation will occur, because the cause of fogging and condensation is the micro-water humidity inside. The innovative structure of the device uses the proton exchange membrane 10 with good chemical stability, proton conductivity, and gas separation as a solid electrolyte, which can effectively prevent electron transfer. The oxygen atoms electrolyzed at the anode are continuously released to the external atmospheric environment through small pores, eliminating the oxygen atoms and oxygen hazards of the electrolyzed oxygen atoms in the anode chamber. The hydrogen atoms electrolyzed at the cathode and the synthesized water molecules and hydrogen diffuse with the external air through the ePTFE microporous breathable protective membrane 6, eliminating the explosive hazards of hydrogen accumulation in the cathode chamber. The innovative structure of the device improves the safety of the electrolysis device and engineering applications.

[0043] The anode platinum carbon Pt / C catalyst layer is the anode catalyst layer 11. The water molecules in its internal space move irregularly at high speed. Some of them collide with the anode side platinum carbon catalyst and the platinum titanium conductive network to cause electrolysis reaction. The electrolytic decomposition reaction equation of water molecules under the action of the anode side platinum carbon catalyst is: 2H2O—O2+4H++4e-, and the electrolysis releases oxygen atoms or molecules, hydrogen protons and electrons.

[0044] The shell is also provided with an elastic sealing ring 3 and an insulating sealing member 2 that cooperate with the DC anode conductor 15 and the DC cathode conductor 13. The insulating sealing member 2 is used to prevent humidity in the external atmosphere from penetrating into the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc.

[0045] The anode platinum titanium Pt / Ti porous foil mesh enhances the efficiency of catalytic electrolysis of water molecules at the anode and increases the area of ​​the anode that collides with the water molecules inside it and the chance of water molecules being electrolyzed.

[0046] The device is assembled and connected with the intelligent helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. The connection methods can be threaded connection, flange screw connection or bayonet installation, etc. A DC voltage of 1.23V to 3V is applied to the anode and cathode of the device. The water molecules in the internal space of the intelligent helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. move irregularly at high speed. Some of them collide with the platinum-carbon catalyst on the anode side and the platinum-titanium conductive net to cause electrolytic reaction. The electrolytic decomposition reaction equation of water molecules under the action of the platinum-carbon catalyst on the anode side is:

[0047] 2H2O—O2+4H + +4e -, oxygen atoms or molecules, hydrogen protons and electrons released by electrolysis;

[0048] Under the action of the platinum-carbon catalyst on the anode side, water molecules release oxygen and its oxygen atoms into the anode chamber and continuously release them to the external atmosphere through small pores. The continuous one-way moisture-permeable coating membrane 14 has the function of one-way moisture-permeable but airtight. The function of the continuous one-way moisture-permeable coating membrane 14 is that the anode electrolysis chamber is separated by the continuous one-way moisture-permeable coating membrane 14 into a chamber connected to the external atmosphere. The water molecules in the separated anode chamber are electrolyzed under the action of the platinum-carbon catalyst on the anode side to release oxygen atoms or molecules, hydrogen protons and electrons; the electrolysis releases The oxygen atoms or molecules released are continuously released to the external atmosphere through the small pores. The separated anode chamber presents a micro-positive pressure dry environment with very low humidity under the action of the electrolysis function. The water molecules in the hot and humid air inside the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc. migrate to the anode chamber through the one-way moisture permeable coating membrane, permeate, diffuse, desorb, and are electrolyzed in the anode chamber. (Moisture permeability is essentially a process of "adsorption-diffusion-transfer-desorption". The hydrophilic group is called a "chemical stepping stone". In the case of pressure difference, the micro-water is transferred from the side with high concentration to the other side with low humidity. This process is also a one-way moisture permeation process. The coating film 14 with continuous one-way moisture permeability has the function of one-way moisture permeability and airtightness, so that the electrical components and circuits installed therein are prevented from being damaged by the corrosion of oxygen-rich atoms, and the internal oxygen concentration level is maintained at the same state as the atmospheric concentration and the risk of spontaneous combustion caused by excessive internal oxygen concentration is avoided; the micro-water content in the air inside it is also continuously reduced under the action of the electrolysis device, and the humidity value continues to decrease, and the inside is kept in a dry state. Even if the dew point of the external environment is very low, the smooth mirror surface of the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. does not have fogging and condensation. This is an important new major innovation of the device, which makes the electronic components, circuits, PI insulation layers, etc. of the internal chips, integrated blocks, etc. of the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. protected from corrosion in the oxygen-rich environment, and their electrical performance is more reliable, the failure rate is lower, and the service life is longer. The H+ electrolyzed under the action of the platinum-carbon catalyst on the anode side flows through the perfluorosulfonic acid proton exchange membrane or the perfluorosulfonic acid proton exchange membrane reinforced with the ePTFE microporous membrane under the action of the DC voltage to reach the cathode side. Under the action of the platinum-carbon catalyst on the cathode side, the H+ forms the following reaction to generate hydrogen molecules or water molecules:

[0049] 4H ++4e—2H2, O2+4H++4e-—2H2O; H+ forms the following reaction under the action of the platinum-carbon catalyst on the cathode side to generate hydrogen molecules or water molecules, which are released into the atmosphere of the external environment through the ePTFE microporous membrane and the external atmospheric convection of the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc., making the hydrogen concentration on the cathode side extremely low and in a safe state.

[0050] The present invention can be connected to the shell of sealed equipment with electronic components such as smart helmet displays, car lights, monitoring probes, image detection, laser radar detection sensors, marine equipment cabinets, etc. in a snap-on, threaded, or port-connected manner, thereby solving the technical problem of accelerating the discharge of internal humidity and permanently keeping the internal air dry without fogging.

[0051] After the present invention is connected to the device housing and the power cord is connected, the power supply of the starter device is turned on, and the active water molecule electrolysis device continuously electrolyzes the water molecules in the air inside these devices (migrates and diffuses into the anode chamber to be electrolyzed), so that the humidity inside these devices decreases rapidly. At the same time, after the device is working, the electrical components inside the device generate heat, so that the internal air pressure increases. Driven by the pressure difference between the inside and outside, the cross-shaped silica gel valve is sensitively opened to discharge the hot and humid air inside the device into the atmosphere. At the same time, the mixture of hygroscopic particulate matter and micropowder particles of a substance that efficiently absorbs far-infrared radiation energy in the device also discharges micro-water into the device, and further dries the mixture of reversible hygroscopic particles under the energy of absorbing thermal infrared, so that the mixture of reversible hygroscopic particles continues to have hygroscopic drying ability after the device stops working, so that the air humidity (dryness) inside the above-mentioned device is much lower than the dew point temperature of the external environment, so that there is no fogging on the internal mirror or smooth surface of the intelligent helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, marine equipment electric cabinets, etc., so that the performance of these devices can be effectively exerted.

[0052] When the above equipment stops working, the temperature of the electrical components and the internal air temperature drop, resulting in the balance of the internal and external pressures, and the internal and external pressure difference is sensitive to close the silicone valve 26, thereby closing the exhaust passage inside and outside the equipment. The mixture of reversible hygroscopic particles of the device of the present invention continues to absorb moisture and dry the air inside the device after the device stops working, so that the humidity of the air inside the device is maintained at a very low state. If the backup power supply is enabled after the above equipment stops working to provide power support for the "active electrolysis water molecule device for unidirectionally reducing the humidity in a limited space by discharging oxygen outward" of the device of the present invention, the functional module of the device of the present invention for electrolyzing the water molecules inside the above equipment works for a long time, and the humidity inside the intelligent helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, marine equipment electrical cabinets, etc. can be permanently reduced, so that the humidity inside is maintained at a very low level in a dry state, and no fogging occurs on the internal mirror or smooth surface; these devices have stopped working for a long time and no fogging occurs on the internal mirror or smooth surface when they are restarted again, ensuring that their performance is effectively exerted (the headlights have a long and bright lighting effect, the monitoring camera is clear, there is no electrical short circuit and no rust on the internal components, etc.).

[0053] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
