Description

Technical Field

[0001] The invention belongs to the technical field of air purification, and in particular relates to a negative ion air purifier. Background Art

[0002] The basic structure of traditional air purifiers, which are mainly composed of general filter cotton and filter mesh, includes an outer shell to provide protection; a fan to drive the air flow and draw air into the machine; filter cotton, the core component, is used to filter particulate matter in the air; the filter mesh is used to block larger particles and protect the filter cotton; an activated carbon layer (not necessarily present) is used to absorb odors, harmful gases, etc.; and an air outlet: the filtered clean air is discharged from here.

[0003] This type of air purifier can effectively filter larger particles such as dust and pollen, but cannot effectively capture ultra-fine particles such as PM2.5, bacteria, viruses, and cannot handle gaseous pollutants. In addition, in an environment with high temperature and humidity, the moisture and organic matter on the filter and filter cotton provide an environment for bacteria to grow, which in turn pollutes the air again.

[0004] Another type of air purifier emphasizes the ability to provide negative ions. The core component is mainly a negative ion generator, which generates negative ions through high-voltage ionization of the air, and static electricity attracts dust, pollen, smoke and other particles in the air, which settle on the ground or other surfaces. Through the above process, the suspended particles in the air are gradually reduced, achieving the purpose of purifying the air.

[0005] Although negative ion generators are widely believed to be able to purify the air, their working principle of high-voltage ionization has also raised some concerns about safety. For example, in the production of ozone, during the high-voltage ionization process, oxygen molecules in the air may be decomposed into oxygen atoms, and some of the oxygen atoms are recombined to form ozone. Excessive ozone can irritate the respiratory tract, and long-term exposure may cause damage to lung function. Furthermore, the high-voltage ionization process will generate electromagnetic radiation, which may pose a potential hazard to human health. In addition, when the negative ion generator is working, it may cause static electricity in the surrounding environment, and the accumulation of static electricity may cause damage to electronic products. Summary of the invention

[0006] In order to solve the shortcomings of traditional air purifiers with filter cotton, filter net or negative ion generator as core components, the present invention proposes an air purifier that can provide ecological grade negative ions, capture pollutants such as large particles or fine particles in the air, and treat gaseous pollutants.

[0007] Technical features of the present invention:

[0008] A laminar filter type negative ion air purifier, comprising a base and a purifier body arranged on the base; characterized in that: the purifier body comprises a shell, the interior of which is provided with an air inlet chamber, a first filter element module, a buffer chamber, a second filter element module, a laminar flow space, and an airflow dynamic device in order from bottom to top; an inner laminar flow tube is provided at the center of the laminar flow space, an outer laminar flow tube is provided at the peripheral position of the laminar flow space, and the outer laminar flow tube surrounds the inner laminar flow tube; the shell is provided with an annular air inlet corresponding to and connected to the air inlet chamber; the shell is provided with a central air outlet and an annular air outlet; the central air outlet corresponds to and connects to the inner Laminar flow tube; the annular air outlet corresponds to and is connected to the outer laminar flow tube; the first filter material group and the second filter material group each include seven layers of nano-scale filter materials, which are stacked in sequence from bottom to top; the first layer is a nano-filter mesh; the second layer is a nano-filter cotton; the third layer is a mixture of nano-porous stone and activated carbon installed in a honeycomb trough mesh; the fourth layer is a nano-filter cotton; the fifth layer is a mixture of nano-porous stone and activated carbon installed in a honeycomb trough mesh; the sixth layer is a nano-filter cotton; the seventh layer is a nano-filter mesh; each of the nano-scale filter materials, the inner laminar flow tube and the outer laminar flow tube contains nanofibers that can catalyze the generation of ecological-grade negative ions.

[0009] In an embodiment of the present invention, the first filter element module further includes a first upper pipe and a first lower pipe combined with the upper and lower parts of the first filter material group; the second filter element module further includes a second upper pipe and a second lower pipe combined with the upper and lower parts of the second filter material group; the first upper pipe and the second lower pipe are socketed with each other, thereby forming the buffer chamber between the first filter element module and the second filter element module.

[0010] In an embodiment of the present invention, the bottom end of the inner laminar flow tube is sleeved on the second upper connecting tube; and the outer laminar flow tube is arranged along the inner wall of the outer shell.

[0011] In an embodiment of the present invention, the inner laminar flow tube and the outer laminar flow tube are both tubular structures with circular cross-sections; or, the inner laminar flow tube is a tubular structure with a circular cross-section, and the outer laminar flow tube is a tubular structure with a multi-fold cross-section; or, the inner laminar flow tube and the outer laminar flow tube are both tubular structures with multi-fold cross-sections.

[0012] In an embodiment of the present invention, the base includes an intelligent control module, which is electrically connected to the airflow power device, a power switch, an air sensor, and a color-changing light set.

[0013] Effects of the present invention:

[0014] The air passes through the multi-layer nano-scale filter materials of the first filter element module and the second filter element module, and after multiple diversions and collisions with the nanofibers of the inner laminar flow tube and the outer laminar flow tube, it can effectively intercept micro-objects in the air, capture bacteria and viruses, and filter out gaseous pollutants and various odors.

[0015] In the process of air passing through the two filter modules, the principle of Brownian motion is used to make the molecules collide with each other, the organic cells break, the cell membrane is damaged, the contents escape, and the bacteria are decomposed and killed, achieving a bactericidal effect.

[0016] The nano-filter materials in the dual filter module can work synergistically with each other. For example, in a mixture of nano-porous stone and activated carbon, the nano-porous stone can decompose and neutralize the air pollutants adsorbed and filtered by the activated carbon, re-activate the adsorption and filtration efficiency of the activated carbon, and extend the reuse time of the activated carbon.

[0017] When air passes through the dual filter module and the inner and outer laminar flow tubes, the special structure of the nanofiltration material and the negative ion catalytic process produce a synergistic effect, causing the air molecules to produce a large number of ecological-grade negative ions under multiple physical effects.

[0018] The invention uses physical methods to catalyze the generation of ecological-grade negative ions. Compared with negative ion generators using traditional high-voltage ionization technology, the invention does not generate ozone and is more energy-saving and environmentally friendly.

[0019] One-touch start makes it easy to purify the air. Users only need to turn on the power switch, and the intelligent control module will automatically start the airflow power device to start the purification operation.

When the air quality changes, the system will respond in real time and automatically adjust the wind speed and purification mode to ensure that the indoor air is always fresh. The unique color-changing light design allows users to grasp the indoor air quality at a glance.

[0021] In order to improve the usability of the product, a standard modular packaging process is adopted to package the first filter element module and the second filter element module separately and independently, and the user can easily remove them from the housing for cleaning and maintenance.

[0064] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0065] like Figures 1 to 3 The layer filter type negative ion air purifier of the present invention comprises a base 10 and a purifier body 20 disposed on the base 10. The base 10 and the purifier body 20 adopt a known assembling and disassembling technical solution so that a general user can assemble and separate the two. The purpose of separating the two is to allow the user to take out the first filter element module 30, the second filter element module 40, the inner laminar flow tube 51 and the outer laminar flow tube 52 described below from the purifier body 20, clean them and then reinstall them.

[0066] The purifier body 20 includes a cylindrical shell 21, and the inside of the shell 21 is provided with an air inlet chamber 22, a first filter element module 30, a buffer chamber 23, a second filter element module 40, a laminar flow space 24, and an airflow dynamic device 60 in order from bottom to top. An inner laminar flow tube 51 is provided at the center of the laminar flow space 24, and an outer laminar flow tube 52 is provided at the peripheral position of the laminar flow space 24, and the outer laminar flow tube 52 surrounds the inner laminar flow tube 51. The shell 21 is provided with an annular air inlet 25 corresponding to and connected to the air inlet chamber 22. The shell 21 is provided with a central air outlet 26 and an annular air outlet 27. The central air outlet 26 corresponds to and is connected to the inner laminar flow tube 51. The annular air outlet 27 corresponds to and is connected to the outer laminar flow tube 52. The first filter element module 30, the second filter element module 40, the inner laminar flow tube 51, and the outer laminar flow tube 52 constitute the core components of the purifier body 20.

[0067] The first filter module 30 includes a first filter material group 31 and a first upper pipe 32 and a first lower pipe 33 respectively connected to the upper and lower parts of the first filter material group 31. The first lower pipe 33 is a cylindrical mesh tube. The second filter module 40 includes a second filter material group 41 and a second upper pipe 42 and a second lower pipe 43 respectively connected to the upper and lower parts of the second filter material group 41.

[0068] In the housing 21, the second filter module 40 is disposed on the first filter module 30, and the first upper pipe 32 and the second lower pipe 43 are sleeved with each other, thereby creating a distance between the first filter module 30 and the second filter module 40, which is the buffer chamber 23. The first lower pipe 33 stands on the top surface of the base 10, thereby creating a distance between the first filter module 30 and the base 10, which is the air inlet chamber 22.

[0069] The first filter material group 31 includes seven layers of nano-scale filter materials, which are stacked in order from bottom to top. The first layer 311 is a nano-filter. The second layer 312 is a nano-filter cotton. The third layer 313 is a mixture of nano-porous stone and activated carbon installed in a honeycomb trough mesh. The fourth layer 314 is a nano-filter cotton. The fifth layer 315 is a mixture of nano-porous stone and activated carbon installed in a honeycomb trough mesh. The sixth layer 316 is a nano-filter cotton. The seventh layer 317 is a nano-filter. All of the filter materials are produced through a technical solution that catalyzes the production of ecological-grade negative ions, so that the filter material contains nanofibers that can catalyze the production of ecological-grade negative ions, and air passes through the filter material to produce ecological-grade negative ions. The technical solution includes but is not limited to the addition of mineral nanoparticles that can produce negative ions, far-infrared treatment, and plasma treatment.

[0070] The second filter material group 41 includes seven layers of nano-scale filter materials, which are stacked in order from bottom to top. The first layer 411 is a nano-filter. The second layer 412 is a nano-filter cotton. The third layer 413 is a mixture of nano-porous stone and activated carbon installed in a honeycomb trough mesh.

The sixth layer 416 is a nano-filter cotton. The seventh layer 417 is a nano-filter. All of the filter materials are produced through a technical solution that catalyzes the production of ecological-grade negative ions, so that the filter material contains nanofibers that can catalyze the production of ecological-grade negative ions, and air passes through the filter material to produce ecological-grade negative ions. The technical solution includes but is not limited to the addition of mineral nanoparticles that can produce negative ions, far-infrared treatment, and plasma treatment.

[0071] In order to improve the usability of the product, a standard modular packaging process is adopted to package the first filter element module 30 and the second filter element module 40 separately and independently, and the user can easily remove them from the housing 21 for cleaning and maintenance.

[0072] like Figure 1 and Figure 2 , regarding the laminar flow space 24 , the inner laminar flow tube 51 , and the outer laminar flow tube 52 .

[0073] The laminar flow space 24 is located between the second filter element module 40 and the airflow dynamic device 60 in the housing 21. The inner laminar flow tube 51 is arranged at the center of the laminar flow space 24, and the outer laminar flow tube 52 is arranged at the periphery of the laminar flow space 24, and the outer laminar flow tube 52 surrounds the inner laminar flow tube 51. The bottom end of the inner laminar flow tube 51 is sleeved on the second upper pipe 42. The outer laminar flow tube 52 is arranged along the inner wall of the housing 21.

[0074] The inner laminar flow tube 51 and the outer laminar flow tube 52 are both tubular bodies made of nanofibers that can catalyze the generation of ecological grade negative ions. Through the technical solution of catalyzing the generation of negative ions, air passes through and collides with the inner laminar flow tube 51 and the outer laminar flow tube 52 to generate more high-concentration ecological grade negative ions. Figure 2 and Figure 4 The inner laminar flow tube 51 and the outer laminar flow tube 52 are both tubular structures with circular cross sections. Figure 5 The inner laminar flow tube 51 is a tubular structure with a circular cross section, and the outer laminar flow tube 52 is a tubular structure with a multi-fold cross section. Figure 6 The inner laminar flow tube 51 and the outer laminar flow tube 52 are both tubular structures with multi-fold cross sections.

[0075] Furu Figure 1 The airflow power device 60 is disposed at the uppermost end of the housing 21. The conventional technology is that the motor drives the fan blades to rotate, and the fan blades cut the air to generate wind pressure, and the wind pressure draws the air into the purifier body 20 from the annular air inlet 25 and forms a forward airflow flowing upward.

[0076] like Figure 7The airflow power device 60 draws external air (as shown by arrow A) from the annular air inlet 25 into the air inlet chamber 22, and forms a forward airflow (as shown by arrow B) through the cylindrical mesh tube-shaped first lower connecting pipe 33; after the airflow passes through the first filter element module 30, the flow resistance is relieved in the buffer chamber 23, and the airflow is diverted due to the action of the first upper connecting pipe 32 and the second lower connecting pipe 43 which are mutually nested, and then enters the second filter element module 40, and finally passes through the inner laminar flow tube 51 and the outer laminar flow tube 52, and is catalyzed by layers of nano-level filtration materials and ecological-level negative ions, and finally becomes clean air with a high concentration of ecological-level negative ions (as shown by arrow C), and is released from the central air outlet 26 and the annular air outlet 27.

[0077] The purification process principle of the present invention is described as follows:

[0078] The air passes through the multi-layer nano-scale filter materials of the first filter element module 30 and the second filter element module 40, and after multiple diversions and collisions with the nanofibers of the inner laminar flow tube 51 and the outer laminar flow tube 52, it can effectively intercept micro-objects in the air, capture bacteria and viruses, and filter out gaseous pollutants and various odors. In the process of air passing through the two filter element modules, the principle of Brownian motion is used to make molecules collide with each other, organic cells break, cell membranes are damaged, and contents escape, causing bacteria to decompose and die, thereby achieving a sterilization effect.

[0079] In addition, when the air passes through the first filter module 30 and the second filter module 40, the porous structure, irregular surface and negative ion catalysis of the nano-filter material cause the air molecules to produce a large number of ecological-grade negative ions (small-particle negative ions) through multiple collisions, frictions and catalytic reactions when flowing through the fourteen layers of nano-filter material, the inner laminar flow tube 51 and the outer laminar flow tube 52. In particular, when the inner laminar flow tube 51 and the outer laminar flow tube 52 adopt a multi-fold design, the air flow contact area can be greatly increased, further improving the efficiency and amount of ecological-grade negative ion generation. The concentration of ecological-grade negative ions contained in the clean air released by the central air outlet 26 and the annular air outlet 27 is significantly increased. Ecological-grade negative ions are small-particle negative ions with high activity and long natural migration distance. They can form an air negative ion bath environment in space. Their strong adsorption force can effectively capture and condense PM2.5 or smaller suspended particles and make them settle, achieving the purpose of purifying the air.

[0080] like Figure 8 , about the base 10. An intelligent control module 70 is arranged therein, and the intelligent control module 70 is electrically connected to the airflow power device 60, a power switch 71, an air sensor 72, and a color-changing light set 73. The color-changing light set 73 includes but is not limited to three light colors, for example, orange indicates poor air quality, yellow indicates ordinary air quality, and green indicates excellent air quality.

[0081] Through the manual mode, the user can press the power switch 71 at any time to start or stop the operation of the air purifier. After the power switch 71 is turned on, the purifier body 20 actively performs the above-mentioned air purification and ecological grade negative ion generation process to effectively remove pollutants and odors in the air.

[0082] Through the built-in intelligent control module 70, the operation mode can be automatically turned on, off or adjusted according to the air quality data measured by the air sensor 72. When the indoor air quality decreases, the color-changing light will display the corresponding color, and the airflow power device 60 will be activated, and the purifier body 20 will actively perform the above-mentioned air purification and ecological level negative ion generation process. As the air quality gradually improves, the color of the color-changing light will gradually change until the air quality reaches excellent, and then it will automatically stop operating.

[0083] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
