Description

Technical Field

[0001] The present invention relates to the technical field of air purification equipment, and in particular to an air purification system and method suitable for a movable enclosed space in a transportation vehicle or a wearable device. Background Art

[0002] The higher the concentration of negative oxygen ions in the air, the more significant the positive impact on human physical and mental state. The World Health Organization also defines the concentration of negative oxygen ions in fresh air as greater than 1500 / cm 3 .

[0003] The Chinese utility model patent with the announcement number CN2600753Y discloses an air purifier, which basically has components such as a housing, a negative oxygen ion generating mechanism, a clamping member, and a power control mechanism, wherein the negative oxygen ion generating mechanism is installed in the housing and has a negative pressure member, a rotating member, a negative oxygen ion generating plate, a conductive clamping member, etc., for generating negative oxygen ions. Since the negative oxygen ion generating mechanism is provided therein, when the air purifier is in operation, the air delivered contains negative oxygen ions, so that the negative oxygen ions absorb smaller dust and bacteria in the air, making the air fresher. This air purifier is small in size, easy to move and install, and suitable for use in small spaces, with convenience and practical effects. In particular, the air purifier is provided with a clamping member, which is clamped at the air outlet of the cold air, so that the air delivered by the cold air carries the negative oxygen ions generated inside the air purifier, so that the negative oxygen ions are dispersed in the air.

[0004] The Chinese utility model patent with the announcement number CN2648327Y discloses a ceiling fan sterilization and air purification device, which is equipped with a motor, which is connected to the fan and connected to the controller with a rotating shaft, and the controller controls the rotation of the motor and the flickering of the cold cathode lamp. Negative oxygen ions are generated by the cold cathode lamp, which can oxidize organic matter and reduce it to inorganic matter, enhance the effect of removing odors, eliminate suspended bacteria in the air, and improve indoor air quality.

[0005] The use environment of existing air purifiers or negative oxygen ion generating devices is mostly in a relatively non-enclosed environment. Even in an indoor environment, there is still appropriate convection between it and the external environment. Modern people spend a lot of time in relatively enclosed mobile vehicles, such as airplanes. Some special people stay in environments such as cabins or submarines for a long time, or are confined to relatively closed wearable devices. In these enclosed mobile vehicles, the requirements for air quality in the past were limited to the levels of bacteria, viruses, odors, etc. in the air, and there has not been any relevant discussion on how to make the air in the enclosed mobile vehicle the same as the air quality in the natural environment. When the quality of the air is to be greatly improved, a high concentration of negative oxygen ions is required in the ambient air. However, although charged gases can bring about differences in physical sensations, the impact of charged gases on electrical equipment in the environment still needs to be considered. Therefore, there is still room for development and breakthroughs in the technology of providing high-quality air in movable enclosed spaces. Summary of the invention

[0006] The purpose of the present invention is to provide an air purification system and method suitable for a movable enclosed space, so that people in the movable enclosed space can enjoy high-quality air and avoid the adverse effects of high-concentration negative ions on important electrical equipment.

[0007] On the one hand, an air purification system suitable for a movable enclosed space includes: a charged gas generating source, which can generate charged gas; a blowing system, which can blow the charged gas away from the charged gas generating source; a circulation system, which can circulate the charged gas in the movable enclosed space; and one or more electrical neutralization devices, which are arranged in the movable enclosed space to neutralize the electrical properties of the charged gas.

[0008] In a specific embodiment, an air purification device has a first space and the charged gas generating source and the blowing system contained in the first space. The charged gas generating source charges the gas in the first space, and the blowing system blows the charged gas in the first space into the circulation system.

[0009] In a specific embodiment, the circulation system has a second space, which is communicated with the first space to receive the charged gas blown out by the blowing system.

[0011] In a specific embodiment, the circulation system has an air inlet channel, and the gas in the movable enclosed space enters the second space through the air inlet channel.

[0012] In a specific embodiment, the air outlet channel is communicated with the air inlet channel.

[0013] In a specific embodiment, the electrical neutralization device is disposed in the air inlet passage to neutralize the electrical properties of the gas entering the circulation system to prevent the charged gas from damaging the air purification device.

[0014] In a specific embodiment, the electrical neutralization device is connected to a ground terminal, and the electrical neutralization device does not share the ground terminal with other electronic devices.

[0015] In a specific embodiment, the movable enclosed space is an enclosed space of a transportation vehicle or an enclosed space of wearable equipment.

[0016] In a specific embodiment, the charged gas generating source is integrated with the blowing system.

[0017] In a specific embodiment, the charged gas generating source comprises a shell, a negative ion generating circuit board is provided in the shell, and an insulating material is filled between the outer surface of the negative ion generating circuit board and the inner wall of the shell. The insulating material filled in the shell effectively limits the movement of static electricity and effectively reduces the accumulation of static electricity. Under the premise of effectively reducing the hazards of static electricity, a high ion emission of the charged gas generating source can be achieved, thereby improving the air purification effect and purification efficiency.

[0018] On the other hand, the present invention proposes a control method for an air purification system, the method comprising N air purification systems, wherein N is an integer greater than or equal to 2, and the control method comprises the following steps: obtaining the optimal operating frequency range of each air purification system when it is in operation; during the operation of the air purification system, if the negative ion concentration of the charged gas in the movable enclosed space is less than a preset target, determining whether the operating frequencies of the air purification systems in operation have reached the upper limit of the optimal operating frequency range, wherein the number of the air purification systems in operation is k, k<N; if each When the operating frequencies of the k+1th air purification system in operation all reach the upper limit of the corresponding optimal operating frequency range, the k+1th air purification system is controlled to start, and when the operating frequency of the k+1th air purification system does not reach the lower limit of the corresponding optimal operating frequency range and the negative ion concentration of the charged gas reaches the preset target, the k air purification systems are controlled to be frequency-reduced and the k+1th air purification system is controlled to be frequency-up, so that when the negative ion concentration of the charged gas reaches the preset target, the operating frequencies of the k+1 air purification systems are controlled to be within the corresponding optimal operating frequency range. This method improves the energy efficiency of the entire system by systematically adjusting the entire system, maximizing the operation of each air purification system within the optimal operating frequency range, and effectively avoiding the problem of low overall energy efficiency of the system caused by some systems operating in the high frequency band and other systems operating in the low frequency band.

[0019] On the other hand, another object of the present invention is to provide an air purification method suitable for a movable enclosed space, comprising: configuring a circulation system having at least one air outlet channel and at least one air inlet channel, the air outlet channel and the air inlet channel both being connected to the movable enclosed space; providing a charged gas generating source in the movable enclosed space; blowing the charged gas generated by the charged gas generating source into the air outlet channel of the circulation system via a blowing system; monitoring the charged gas in the movable enclosed space, and controlling the charged gas generating source and / or the circulation system according to whether the concentration of negative ions in the space meets a preset range; and providing an electrical neutralization device in the movable enclosed space to isolate the electrical equipment in the movable enclosed space.

[0020] Compared with the prior art, the technical solution of the present invention has the following characteristics and advantages:

[0021] Utilizing a charged gas generating source to generate charged gas with a high concentration of negative ions and installing an electrical neutralization device in a movable enclosed space can not only allow personnel in the movable enclosed space to enjoy high-quality air, but also avoid the adverse effects of high-concentration negative ions on important electrical equipment.

[0027] The invention will be described more fully below with reference to the accompanying drawings, and specific embodiments within specific examples are shown by way of illustration. However, the subject matter described herein may be embodied in many different forms, and thus the construction of the subject matter covered or claimed is not limited to any exemplary embodiment disclosed in this specification; the exemplary embodiments are merely illustrative. Likewise, the application documents of this invention are intended to provide a reasonably broad scope of protection for the claimed subject matter claimed or covered. In addition, the drawings and illustrations in this invention are generally not drawn to scale and are not intended to correspond to actual relative dimensions.

[0028] For the purpose of consistency and ease of understanding, the same features are indicated by reference numerals in the exemplary drawings (although not so indicated in some examples). However, the features in different embodiments may differ in other aspects and should not be narrowly limited to the features shown in the drawings. The terms "first" and "second" in the specification of the present invention and the above drawings are used to distinguish different objects, rather than to describe a specific order.

[0029] The air purification system proposed in the present invention is suitable for movable enclosed spaces, such as enclosed spaces in mobile vehicles, that is, enclosed spaces in transportation vehicles (aircraft, ships, submarines, vehicles, railways, high-speed trains) or wearable devices (helmets, diving equipment, astronaut equipment). The mobile vehicle or wearable device can be equipped with a circulation system, and the air purification system provides at least one air outlet channel and at least one air inlet channel connected to the movable enclosed space. The air purification system of the present invention also includes an air purification device, which generates charged gas, and the charged gas has a high concentration of negative ions.

[0030] The "confined space" mentioned in the present invention is not completely closed, but refers to an internal space that does not produce convection with the external space for a long time, or refers to an internal space that has only a small amount of air convection with the external space for a long time, such as an airplane cabin space, a ship cabin space, the internal space of a submarine, and special-purpose helmets. The oxygen content of these movable confined spaces will decrease over time, while the carbon dioxide will increase over time, causing the personnel staying in the movable confined space to have reduced performance when performing work. The "negative ions" mentioned in the present invention do not limit the type of negative ions, and can refer to the form of hydroxide ions attached to water (H2O+OH － ), the form in which oxygen ions attach to water (O 2- +H2O) and / or carbon tetroxide in the form of water (CO4 4- +H2O).

[0031] Air containing high concentration of negative ions is introduced into the movable enclosed space, so that the number of negative ions per cubic centimeter in the movable enclosed space (such as the concentration of negative ions) is increased to a preset range. Preferably, the preset range is greater than 1500 / cm3 .

[0032] The charged gas generating source is used to obtain the air with negative ions. Generally speaking, the charged gas generating source has a high voltage generator, which can generate negative ions by contacting the air at a discharge end, and the discharge end can be arranged near the gas outlet channel.

[0033] A blowing system (such as a fan) is used to maintain air flow at the discharge end, so that oxygen continuously flows through the discharge end to continuously generate charged gas with negative ions.

[0034] The discharge end of the charged gas generating source is arranged near the air outlet channel of the circulation system. Through the operation of the blowing system, the high concentration of negative ions generated by the contact between the discharge end and the air are blown out of the air outlet channel, thereby forming an air circulation with a high concentration of negative ions in the enclosed space of the mobile vehicle.

[0035] Figure 1 Schematic diagram of the air purification system of the present invention. The air purification system 1 of the present invention can be installed in a transportation vehicle 2, such as an airplane cabin or a submarine cabin.

[0036] The air purification system 1 includes an air purification device 11 and a circulation system 12 , which are connected to each other in a communicable manner.

[0037] The air purifier 11 has a charged gas source 11A and a blowing system 11B. The charged gas source 11A is controlled by a controller to generate a high-voltage electric field to ionize the air to obtain charged gas, and the charged gas has negative ions. The charged gas source 11A ionizes the air in a first space, and the first space refers to the space located in the air purifier 11 and around the charged gas source 11A, but the present invention is not limited to this. The blowing system 11B is arranged near the charged gas source 11A and is configured to form convection to carry away the charged gas ionized by the charged gas source 11A, so that the charged gas enters the circulation system 12. The blowing system 11B may include one or more electric fans, which are controlled by the controller to determine the wind speed or gas flow direction.

[0038] Alternatively, the charged gas generating source 11A and the blowing system 11B are integrated, for example, the blowing system 11B may include one or more electric fans, and the charged gas generating source 11A is arranged next to the blades of the electric fans. By compactly assembling the electric fan of the blowing system 11B and the charged gas generating source 11A, the structure is simple; when the electric fan is running, it promotes the rapid diffusion of the negative ions generated by the charged gas generating source 11A, which can effectively and quickly increase the indoor negative ion content and improve the indoor environment.

[0039] The charged gas generating source 11A includes a shell, a negative ion generating circuit board is provided in the shell, and an insulating material is filled between the outer surface of the negative ion generating circuit board and the inner wall of the shell. The insulating material filled in the shell effectively limits the movement of static electricity and effectively reduces the accumulation of static electricity. Under the premise of effectively reducing the hazards of static electricity, the high ion emission of the charged gas generating source 11A can be achieved, thereby improving the air purification effect and purification efficiency.

[0040] A second space is defined in the circulation system 12, and the second space is connected to the first space of the air purification device 11. The circulation system 12 has an outlet channel 12A and an inlet channel 12B, both of which are connected to the second space and the enclosed space of the transportation vehicle 2. The second space of the circulation system 12 is connected to the first space through the outlet channel 12A, so that the charged gas blown out by the blowing system 11B can enter the outlet channel 12A of the circulation system 12 and be discharged into the enclosed space. The inlet channel 12B receives the gas from the enclosed space and recycles it into the circulation system 12. The ion concentration of the recovered gas may be low due to dilution or neutralization. The recovered charged gas can then go to the outlet channel 12A through a specific path in the second space and mix with the charged gas blown from the first space to the outlet channel 12A.

[0041] The air purification system 1 of the present invention also includes one or more electrical neutralization devices 13. The electrical neutralization device 13 is used to reduce or neutralize the electrical properties of the charged gas to prevent high concentrations of negative ions from contacting other electrical equipment and causing problems such as static electricity damage or electromagnetic interference. The electrical neutralization device 13 is mainly made of metal and can be formed into different shapes, such as mesh, sheet or block. Figure 1 In an embodiment, the electrical neutralization device 13 is arranged in a mesh form on the air inlet channel 12B of the circulation system 12. Alternatively, the electrical neutralization device 13 can be configured at an appropriate position in the enclosed space of the transportation vehicle 2, for example, arranged in a mesh or sheet form on the bulkhead of an aircraft cabin or on the bulkhead of a ship cabin. The electrical neutralization device 13 is connected to a ground terminal so that the electrical neutralization device 13 itself is at zero potential or low potential. In one embodiment, the circulation system 12 can be arranged along the cavity wall of the enclosed space, and multiple air outlet channels 12A and multiple air inlet channels 12B are dispersed in the enclosed space, and multiple electrical neutralization devices 13 can be arranged to separate the electrical equipment from the enclosed space, so that when the charged gas in the enclosed space flows to the electrical equipment, it must pass through the electrical neutralization device 13, thereby reducing the charge of the gas and avoiding affecting the operation of the electrical equipment.

[0042] An ion concentration detector may be provided in the confined space to monitor the negative ion concentration of the charged gas in the confined space and transmit the detection result back to the controller. The controller may regulate the operation of the charged gas generating source 11A, the blowing system 11B and the circulation system 12 according to the real-time negative ion concentration value or the average negative ion concentration value.

[0043] Figure 2 This is a flow chart of the air purification method of the present invention, including steps S200 to S208.

[0044] Step S200: configure a circulation system 12 having at least one outlet channel 12A and at least one inlet channel 12B, wherein both the outlet channel 12A and the inlet channel 12B are connected to the movable enclosed space. In one embodiment, the circulation system 12 can reach multiple locations of the movable enclosed space to ensure that each area in the movable enclosed space can be effectively circulated.

[0045] Step S202: In the movable enclosed space, a charged gas generating source 11A is provided. The charged gas generating source 11A can be regulated by a controller to generate charged gas. The concentration of negative ions in the charged gas can be controlled within a range of 1500 / cm 3 Up to 5000 pieces / cm 3 In between, or even higher.

[0046] Step S204: The charged gas generated by the charged gas generating source 11A is blown into the outlet channel 12A of the circulation system 12 through a blowout system 11B. The blowout system 11B and the circulation system 12 are appropriately configured to allow the charged gas to flow to the outlet channel 12A, but not to flow back to the inlet channel 12B.

[0047] Step S206: Monitor the charged gas in the movable enclosed space and determine whether the negative ion concentration in the space meets a preset range (e.g., 1500 / cm 3 Up to 5000 pieces / cm 3 ) to control the charged gas generating source 11A and / or the circulation system 12. A plurality of ion concentration detectors may be provided in the movable enclosed space to read specific negative ion concentration values ​​and transmit them back to the controller, thereby regulating the operation of the charged gas generating source 11A and the circulation system 12.

[0048] Step S208: Provide an electrical neutralization device 13 in the movable enclosed space to isolate the electrical equipment in the movable enclosed space and protect the electrical equipment from electrostatic damage or signal interference caused by charged gas. The electrical neutralization device 13 is placed on a metal surface, and the metal surface is at zero potential or low potential.

[0049] In summary, the present invention proposes an air purification system and method suitable for a movable enclosed space, which utilizes a charged gas generating source 11A to generate charged gas with a high concentration of negative ions, and sets an electrical neutralization device 13 in the movable enclosed space. This not only allows people in the movable enclosed space to enjoy high-quality air, but also avoids the adverse effects of high-concentration negative ions on important electrical equipment.

[0050] The present invention also proposes another control method for an air purification system, the method comprising N air purification systems, wherein N is an integer greater than or equal to 2, and the control method comprises the following steps: obtaining the optimal (compressor) operating frequency range of each air purification system when it is in operation; during the operation of the air purification system, if the negative ion concentration of the charged gas in the movable enclosed space is less than a preset target, determining whether the operating frequencies of the air purification systems in operation have all reached the upper limit of the optimal operating frequency range, wherein the number of the air purification systems in operation is k, k<N; if When the operating frequency of each air purification system in operation reaches the upper limit of the corresponding optimal operating frequency range, the k+1th air purification system is controlled to be turned on, and when the operating frequency of the k+1th air purification system does not reach the lower limit of the corresponding optimal operating frequency range and the negative ion concentration of the charged gas reaches the preset target, the k air purification systems are controlled to be down-frequency controlled and the k+1th air purification system is controlled to be up-frequency controlled, so that when the negative ion concentration of the charged gas reaches the preset target, the operating frequencies of the k+1 air purification systems are controlled to be within the corresponding optimal operating frequency range. This method improves the energy efficiency of the entire system by systematically adjusting the entire system, maximizing the operation of each air purification system within the optimal operating frequency range, and effectively avoiding the problem of low overall energy efficiency of the system caused by some systems operating in the high frequency band and other systems operating in the low frequency band.

[0051] It should be understood that the specific embodiments of the present invention are only for illustrative purposes, and various changes can be made without departing from the protection scope of the present invention, and all should be included in the protection scope of the present invention.
