Description

Technical Field

[0001] This utility model relates to the technical field of air purification devices, specifically a water-filter type air purification device. Background Technology

[0002] An air purifier is an electrical appliance used to improve indoor air quality. It draws in surrounding air through a built-in fan and purifies the air using various methods such as physical filtration (e.g., HEPA filters to intercept dust, pollen, and other suspended particles), adsorption (e.g., activated carbon to remove odors, formaldehyde, and other gaseous pollutants), or decomposition (e.g., photocatalysis, negative ion technology). The clean air is then released back into the indoor space. It is mainly used in enclosed or semi-enclosed environments such as homes, offices, and hospitals.

[0003] Air purifiers can reduce air pollutants and improve respiratory health and environmental comfort, but they still have certain problems: 1) Traditional spray technology generates micron-sized water vapor due to high-pressure atomization, causing air humidity to soar; 2) Traditional water filter air purifiers often experience water vapor backflow and corrosion of circuits because the air and water paths are not physically isolated; 3) Dust removal efficiency is low. Therefore, in view of the above situation, there is an urgent need to develop a water filter air purifier to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a water-filter type air purification device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-filter type air purification device, comprising:

[0006] The outer casing has air inlets on its side walls and exhaust vents on its top.

[0007] The water filter module is installed inside the housing; the water filter module includes:

[0008] The water tank, located at the bottom inside the outer casing, is used for storing and collecting circulating water;

[0009] The filtration mechanism includes: a housing, an intake pipe, an acceleration pipe, a fan, a flow guide assembly a, a flow guide assembly b, and an exhaust pipe. The housing is cylindrical and hollow with several drainage grooves installed at the bottom. Two intake pipes pass through both sides of the housing and are arranged tangentially. The acceleration pipe is fixed at the intake end of the intake pipe. The fan is installed at the intake end of the acceleration pipe. Several sets of flow guide assemblies a and b are installed inside the housing. The exhaust pipe passes through the axial position of the housing, and the section of the pipe extending into the housing has flow guide holes.

[0010] The flow guide layer is detachably installed on the top of the shell and includes a through groove a, a through groove b, a flow guide groove, a sleeve a, and a locking block. Several through grooves a and b are installed at the bottom of the flow guide layer and are vertically aligned with the water collection trough a and the water collection trough b, respectively. The flow guide groove is located at the edge of the flow guide layer and is arc-shaped. The sleeve a is located at the axial position. The locking block is fixed at the lower surface edge of the flow guide layer.

[0011] The top cover is detachably installed on the flow guide layer and is provided with mounting holes and sleeve b, wherein sleeve b is nested at the top of sleeve a;

[0012] The circulation pipe is used to connect the water tank and the top cover;

[0013] The air intake shroud is installed on the inner wall of the housing and located between the air intake and the fan.

[0014] Specifically, the tangentially installed intake pipe, combined with the fan and acceleration pipe, forms a high-speed swirling airflow. Inside the cylindrical housing, this airflow fully contacts the water column formed by the tortuous guide shaft of guide component a, the water curtain formed by the guide net of guide component b, and the vertical water curtain formed by the guide groove along the inner wall of the housing, achieving multi-stage dust collection. At the same time, the low-position guide hole design of the exhaust pipe reduces water vapor carry-out, effectively maintaining air humidity balance. The swirling design enhances air-water contact efficiency, and the variable diameter acceleration pipe increases the intake speed. Combined with the pre-filtration of the primary filter screen inside the air collection hood, fan energy consumption is reduced. The overall structure achieves modular quick disassembly through the interlocking of the locking blocks and sleeves a and b, facilitating maintenance.

[0015] Preferably, the flow guiding component a includes a base a, a plurality of flow guiding shafts vertically mounted on the base a, and a water collection trough a sleeved on the top of the flow guiding shafts; the flow guiding component b includes a base b, a flow guiding net vertically mounted on the base b, and a water collection trough b sleeved on the top of the flow guiding net; wherein, the plurality of flow guiding components a are radially distributed along the circumferential direction of the inner wall of the shell, and the plurality of flow guiding components b are radially distributed along the circumferential direction of the middle part of the shell.

[0016] Specifically, the radial distribution design of the flow guiding component a and the flow guiding component b works synergistically: the flow guiding component a forms a dense water column through the twisted flow guiding shaft fixed by the base a and the water collection tank a, and the flow guiding component b forms a radial water curtain in the middle of the shell through the flow guiding net supported by the base b and the water collection tank b. This allows the tangentially entering swirling air to collide with the water column on the inner wall and the water curtain in the middle in multiple stages, which greatly improves the dust collection efficiency. At the same time, the radial layout ensures that the airflow passes evenly through the water film coverage area, avoids vortex dead zones, achieves ultra-high dust removal rate and reduces water mist escape under low wind resistance.

[0017] Preferably, the water tank is equipped with a filter tank, which is filled with filter media.

[0018] Preferably, the guide shaft has a twisted structure and the distance between adjacent guide shafts is greater than 2mm; both water collection tank a and water collection tank b have through holes at the bottom for guiding water through the guide shaft and the guide net to form water columns and water curtains respectively.

[0019] Specifically, the twisted guide shaft, combined with a shaft spacing of more than 2mm, causes the water flow to form a continuous, spiraling water column on the surface of the guide shaft, rather than discrete water droplets. At the same time, the through holes at the bottom of water collection tanks a and b precisely guide the water to the guide shaft, and the guide net forms an intermittent water column and a complete water curtain. This structure replaces the traditional high-pressure spray by enhancing the continuity of the attached water film, which greatly reduces water atomization while efficiently capturing dust. It fundamentally prevents the airflow from carrying micron-sized water vapor out of the exhaust pipe, and completely solves the problem of excessive air humidity caused by traditional spray-type purifiers.

[0020] Preferably, a sealing ring is provided between the exhaust pipe and the guide layer and the top cover.

[0021] Specifically, the sealing rings installed between the exhaust pipe, the guide layer, and the top cover completely isolate the water and air paths through multiple sealing protections: during the negative pressure suction process when the swirling air enters the exhaust pipe through the guide hole, this sealing structure can prevent the water flowing in the guide layer from seeping into the exhaust pipe from the nested gap of the sleeve a / b, while avoiding water mist escaping from the top cover interface due to high-speed airflow disturbance. From a physical isolation perspective, it ensures that the dry air after dust removal is completely separated from the circulating water system, eliminating the potential for humidity fluctuations caused by water vapor mixing into the airflow.

[0022] Preferably, the accelerator tube is a variable diameter tube, whose diameter decreases along the airflow direction.

[0023] Specifically, the variable-diameter acceleration tube accelerates the airflow output by the fan by decreasing its diameter, giving dust particles higher kinetic energy and enhancing the subsequent collision and adsorption efficiency with the water column of the guide shaft and the water curtain of the guide net; at the same time, when the high-speed airflow is introduced into the shell through the tangential air intake tube, it forms a stronger swirling centrifugal force, forcing dust particles to be thrown towards the vertical water curtain on the inner wall of the shell, saving energy while completely avoiding the water vapor entrainment problem caused by high-pressure spray.

[0024] Preferably, the guide channel is used to guide water to form an arc-shaped vertical water curtain on the inner wall of the shell.

[0025] Specifically, the arc-shaped design of the guide channel precisely matches the tangent angle of the inner wall of the cylindrical shell, allowing the water flow to form a continuous vertical water curtain along the wall. When the swirling air washes over the inner wall, this ultra-thin water curtain generates a viscous boundary layer effect—at the moment when dust particles collide with the wall due to centrifugal force, the water film completely encapsulates and captures them through surface tension. Compared with the traditional spray mode, the dust removal efficiency is improved. At the same time, the continuous laminar flow characteristics of the water curtain completely eliminate water splashing, making the gas-liquid contact process almost atomized, thus eliminating the risk of humidity runaway from a physical mechanism.

[0026] Preferably, a primary filter screen is installed inside the gas collection hood.

[0027] Preferably, the circulation pipeline includes a circulation pump, a water inlet pipe, a transfer pipe, and a deluge pipe. The circulation pump is installed inside the water tank, the water inlet pipe is installed between the outlet of the circulation pump and the top cover, and the deluge pipe is installed at the end of the water inlet pipe located inside the top cover via the transfer pipe.

[0028] Specifically, the integrated design of the circulation pipeline breaks through traditional limitations through four-stage precise water control: the circulation pump directly draws clean water filtered by the filter tank, which is then vertically transported to the top cover via the water supply pipe. An adjustable-angle adapter pipe connects to the porous rain shower pipe, ensuring that the water flow evenly covers the surface of the guide layer. This layout utilizes the discrete dripping pattern of the rain shower pipe in conjunction with the through-channels a, through-channel b, and guide channels of the guide layer to decompose the water flow into three precise delivery paths—injected into water collection tank a to form a spiral water column, flowing into water collection tank b to generate a radial water curtain, and spreading along the arc-shaped guide channel to form a wall water film. Under the premise of completely avoiding high-pressure atomization, it maximizes the air-water contact area with extremely low water consumption, making it more water-saving than traditional spray systems and completely eliminating humidity disturbances.

[0029] Compared with the prior art, this utility model provides a water-filter type air purification device, which has the following beneficial effects:

[0030] It achieves dust filtration by combining a swirling aerodynamic layout with a laminar water film. The variable-diameter acceleration tube drives dust particles to collide at high speed with the spiral water column formed by the tortuous guide shaft and the radial water curtain constructed by the guide net. Combined with the ultra-thin continuous water film laid on the inner wall of the cylindrical shell by the guide groove, it achieves three-stage centrifugal adsorption dust removal. The fully sealed drainage pipe and circulation system prevent water atomization, maintaining the absolute humidity fluctuation of the air while improving the dust removal efficiency.

[0051] Example:

[0052] Please see Figures 1-16 This utility model provides a technical solution: a water-filter type air purification device, comprising:

[0053] The outer casing 10 has an air inlet 110 on its side wall and an exhaust 120 on its top.

[0054] Water filter module 20 is installed inside housing 10; water filter module 20 includes:

[0055] Water tank 210, located at the bottom inside the outer casing 10, is used for storing water and collecting circulating water;

[0056] The filtration mechanism 230 includes: a housing 231, an air inlet pipe 232, an acceleration pipe 233, a fan 234, a flow guide assembly a 235, a flow guide assembly b 236, and an exhaust pipe 237. The housing 231 is cylindrical and hollow, and has several drainage grooves 2311 installed at the bottom. Two air inlet pipes 232 pass through both sides of the housing 231 and are arranged tangentially. The acceleration pipe 233 is fixed at the air inlet end of the air inlet pipe 232. The fan 234 is installed at the air inlet end of the acceleration pipe 233. Several sets of flow guide assemblies a 235 and flow guide assemblies b 236 are installed inside the housing 231. The exhaust pipe 237 passes through the axial position of the housing 231, and the section of the pipe extending into the housing 231 has a flow guide hole 2371.

[0057] The flow guiding layer 240 is detachably installed on the top of the housing 231 and includes a through groove a241, a through groove b242, a flow guiding groove 243, a sleeve a244, and a locking block 245. Several through grooves a241 and through grooves b242 are installed at the bottom of the flow guiding layer 240 and are vertically aligned with the water collection tank a2353 and the water collection tank b2363, respectively. The flow guiding groove 243 is located at the edge of the flow guiding layer 240 and is arc-shaped. The sleeve a244 is located at the axial position. The locking block 245 is fixed at the lower surface edge of the flow guiding layer 240.

[0058] The top cover 250 is detachably installed on the flow guide layer 240 and is provided with a mounting hole 251 and a sleeve b252, wherein the sleeve b252 is nested at the top of the sleeve a244;

[0059] The circulation pipe 220 is used to connect the water tank 210 and the top cover 250;

[0060] The air intake shroud 260 is installed on the inner wall of the housing 10 and located between the air intake 110 and the fan 234.

[0061] Specifically, the tangentially installed intake pipe 232, combined with the fan 234 and the acceleration pipe 233, forms a high-speed swirling airflow. This airflow fully contacts the water column formed by the tortuous guide shaft 2352 of the guide component a235, the water curtain formed by the guide net 2362 of the guide component b236, and the vertical water curtain formed by the guide groove 243 along the inner wall of the casing within the cylindrical housing. This achieves multi-stage dust collection. At the same time, the low-position guide hole 2371 of the exhaust pipe 237 is designed to reduce water vapor carry-out, effectively maintaining air humidity balance. The swirling design enhances air-water contact efficiency, and the variable diameter acceleration pipe 233 increases the intake speed. Combined with the pre-filtration of the primary filter screen in the air collection hood 260, the energy consumption of the fan 234 is reduced. The overall structure achieves modular quick disassembly through the nesting of the locking block 245 and the sleeves a244 and b252, facilitating maintenance.

[0062] Preferably, the flow guiding component a235 includes a base a2351, a plurality of flow guiding shafts 2352 vertically mounted on the base a2351, and a water collection trough a2353 sleeved on the top of the flow guiding shafts 2352; the flow guiding component b236 includes a base b2361, a flow guiding net 2362 vertically mounted on the base b2361, and a water collection trough b2363 sleeved on the top of the flow guiding net 2362; wherein, the plurality of flow guiding components a235 are radially distributed along the inner wall of the shell 231, and the plurality of flow guiding components b236 are radially distributed along the middle part of the shell 231.

[0063] Specifically, the radial distribution design of the flow guiding component a235 and the flow guiding component b236 works synergistically: the flow guiding component a235 forms a dense water column through the twisted flow guiding shaft 2352 fixed by the base a2351 and the water collection tank a2353. Combined with the flow guiding component b236, which is supported by the flow guiding net 2362 of the base b2361 and the water collection tank b2363, a radial water curtain is formed in the middle of the shell. This allows the tangentially entering swirling air to collide with the water column on the inner wall and the water curtain in the middle in a multi-stage process, which greatly improves the dust collection efficiency. At the same time, the radial layout ensures that the airflow passes evenly through the water film coverage area, avoids vortex dead zones, achieves ultra-high dust removal rate and reduces water mist escape under low wind resistance.

[0064] Preferably, the water tank 210 is provided with a filter tank 211, and the filter tank 211 is filled with filter media.

[0065] Preferably, the guide shaft 2352 has a twisted structure, and the distance between adjacent guide shafts 2352 is greater than 2mm; the bottom of the water collection tank a2353 and the water collection tank b2363 are both provided with through holes, which are used to guide water to the guide shaft 2352 and the guide net 2362 respectively to form a water column and a water curtain.

[0066] Specifically, the twisted guide shaft 2352, combined with a shaft spacing of more than 2mm, causes the water flow to form a continuous, spiraling water column on the surface of the guide shaft 2352, rather than discrete water droplets. At the same time, the through holes at the bottom of the water collection tanks a2353 and b2363 precisely guide the water to the guide shaft 2352 and the guide net 2362 to form an intermittent water column and a complete water curtain. This structure replaces the traditional high-pressure spray by enhancing the continuity of the attached water film, which greatly reduces water atomization while efficiently capturing dust. It fundamentally prevents the airflow from carrying micron-sized water vapor out of the exhaust pipe 237, and completely solves the problem of excessive air humidity caused by traditional spray-type purifiers.

[0067] Preferably, a sealing ring 2372 is provided between the exhaust pipe 237 and the guide layer 240 and the top cover 250.

[0068] Specifically, the sealing ring 2372 set between the exhaust pipe 237 and the guide layer 240 and the top cover 250 completely isolates the water path and the air path through multiple sealing protections: during the negative pressure suction process of swirling air entering the exhaust pipe 237 through the guide hole 2371, this sealing structure can prevent the water flowing in the guide layer 240 from seeping into the exhaust pipe 237 through the nested gap of the sleeve a244 / b252, and at the same time avoid water mist from escaping from the interface of the top cover 250 due to high-speed airflow disturbance. From the perspective of physical isolation, it ensures that the dry air after dust removal is completely separated from the circulating water system, and eliminates the hidden danger of humidity fluctuation caused by water vapor mixing into the airflow.

[0069] Preferably, the accelerator tube 233 is a variable diameter tube, whose diameter decreases along the airflow direction.

[0070] Specifically, the variable-diameter acceleration tube 233 accelerates the airflow output by the fan 234 through its decreasing diameter, enabling dust particles to gain higher kinetic energy and enhancing the subsequent collision and adsorption efficiency with the water column of the guide shaft 2352 and the water curtain of the guide net 2362. At the same time, when the high-speed airflow is introduced into the housing 231 through the tangential air intake tube 232, it forms a stronger swirling centrifugal force, forcing dust particles to be thrown towards the vertical water curtain on the inner wall of the housing 231, saving energy while completely avoiding the water vapor entrainment problem generated by high-pressure spray.

[0071] Preferably, the guide channel 243 is used to guide water to form an arc-shaped vertical water curtain on the inner wall of the housing 231.

[0072] Specifically, the arc design of the guide channel 243 precisely matches the tangential angle of the inner wall of the cylindrical shell 231, so that the water flow forms a continuous vertical water curtain along the wall. When the swirling air washes the inner wall, the ultra-thin water curtain generates a viscous boundary layer effect. At the moment when dust particles hit the wall due to centrifugal force, the water film completely wraps and captures them through surface tension. Compared with the traditional spray mode, the dust removal efficiency is improved. At the same time, the continuous laminar flow characteristics of the water curtain completely eliminate water splashing, so that the gas-liquid contact process achieves almost zero atomization, thus eliminating the risk of humidity runaway from a physical mechanism.

[0073] Preferably, a primary filter screen is installed inside the gas collection hood 260.

[0074] Preferably, the circulation pipeline 220 includes a circulation pump 221, a water inlet pipe 222, a transfer pipe 223, and a deluge pipe 224. The circulation pump 221 is installed inside the water tank 210, the water inlet pipe 222 is installed between the outlet of the circulation pump 221 and the top cover 250, and the deluge pipe 224 is installed at the end of the water inlet pipe 222 located inside the top cover 250 via the transfer pipe 223.

[0075] Specifically, the integrated design of the circulation pipeline 220 breaks through traditional limitations through four-stage precise water control: the circulation pump 221 directly draws clean water filtered by the filter tank 211, and then vertically transports it to the top cover 250 through the water supply pipe 222. The adjustable angle adapter pipe 223 connects to the porous rain pipe 224, so that the water flow evenly covers the surface of the guide layer 240. This layout utilizes the discrete dripping mode of the rain pipe 224 in conjunction with the through grooves a241, through grooves b242 and guide grooves 243 of the guide layer 240 to decompose the water flow into three precise delivery paths—injected into the water collection tank a2353 to form a spiral water column, flowing into the water collection tank b2363 to generate a radial water curtain, and spreading along the arc-shaped guide groove 243 to form a wall water film. Under the premise of completely avoiding high-pressure atomization, it maximizes the air-water contact area with extremely low water consumption, which is more water-saving than the traditional spray system and completely eliminates humidity disturbance.

[0076] Working principle: External air enters the air collection hood 260 through the air inlet 110 of the outer casing 10, and completes primary filtration with the primary filter inside the air collection hood 260. Driven by the fan 234, it is accelerated through the variable diameter acceleration pipe 233 and forms a high-speed vortex inside the cylindrical casing 231 through the tangential air inlet pipe 232. At the same time, the circulation pump 221 delivers water from the water tank 210 to the deluge pipe 224 through the water inlet pipe 222. The water flow is precisely injected into the water collection tanks a2353 and b2363 through the through grooves a241 and b242 of the guide layer 240, and spreads along the guide groove 243. Among them, the water collection tank a2353 flows towards... The guide shaft 2352 releases water to form a spiral water column, the water collection tank b2363 releases water to the guide net 2362 to form a radial water curtain, and the guide groove 243 generates a vertical water film on the inner wall of the shell 231. The swirling air impacts the three-layer water structure (water column-water curtain-water film) in sequence. After the dust is captured by the water, the sewage flows back to the water tank 210 with filter tank 211 through the drainage tank 2311 for filtration. The filter tank 211 is filled with filter cotton. The clean air enters through the guide hole 2371 of the exhaust pipe 237, and after being sealed by the sealing ring 2372 to isolate water vapor, it is output from the exhaust hole 120, realizing a triple purification closed loop of dust removal, humidity control and energy saving.
