Description

Technical Field

[0001] The present invention relates to an air purification device, and specifically, to a water-washing air purification device. Background Art

[0002] With the increasingly deteriorating environment, especially the problem of air pollution has attracted more and more attention. Particularly in our country, the air pollution situation is extremely serious, and PM2.5 seriously exceeds the standard. These pollutants entering the human body will have a very adverse impact on people's physical health. Therefore, people have become more and more concerned about how to purify the air, and various air purifiers have emerged as the times require. Currently, the air purifiers on the market all use the method of dry multi-layer filtration and adsorption (such as electrostatic adsorption, activated carbon adsorption, HEPA filtration, etc.) to purify the air, and are equipped with various catalytic and decomposition methods. When such air purifiers are working, pollutants will directly accumulate on the filter screen of the filtration device. If accumulated for a long time, the pores on the filter screen will be blocked, affecting the air filtration effect. The dust accumulated on the filter screen will become a breeding ground for bacteria and form secondary pollution.

[0003] Therefore, in view of the above problems, a water-washing air purifier has been introduced on the market currently. After the air enters the air purifier, it will first pass through water-washing, thereby washing away some large particulate dust in the air, thus well solving the above problems.

[0004] However, for the current water-washing purifiers on the market, after the air enters the purifier, it will only pass through a water curtain washing once, and a lot of air is directly discharged without passing through water-washing, and the purification effect is not ideal.

[0005] Therefore, providing a water-washing air purification device in which air can pass through multi-stage water-washing is an urgent problem to be solved by the present invention. Summary of the Invention

[0006] Aiming at the above technical problems, the purpose of the present invention is to overcome the current water-washing purifiers on the market. After the air enters the purifier, it will only pass through a water curtain washing once, and a lot of air is directly discharged without passing through water-washing, and the purification effect is not ideal. Thus, a water-washing air purification device in which air can pass through multi-stage water-washing is provided.

[0007] To achieve the above object, the present invention provides a water-washing air purification device, which comprises: a housing, a water storage tank, a ventilation pipe, a water pump and a spray pipe. The water storage tank is arranged at the bottom of the housing. The ventilation pipe is arranged above the water storage tank, and a first spiral guide pipe is coaxially arranged inside it. The water pump is arranged in the water storage tank, and its water outlet is arranged vertically upward. The spray pipe is coaxially and vertically arranged inside the first spiral guide pipe, and its water inlet is communicated with the water outlet of the water pump. The upper end of the spray pipe extends out of the first spiral guide pipe and is provided with a spray head, and a plurality of spray holes adapted to the first spiral guide pipe are spaced around its pipe body.

[0008] Preferably, atomizing nozzles and flat-head atomizing nozzles are respectively arranged at the spray holes and the water outlet holes of the spray head.

[0009] Preferably, the water outlet of the flat-head atomizing nozzle is in an arc shape adapted to the spray head.

[0010] Preferably, a second spiral guide pipe is coaxially arranged in the water storage tank, and a reverse osmosis filter membrane is arranged at the water outlet of the second spiral guide pipe.

[0011] Preferably, a cover is detachably arranged on one side of the housing, and a handle is embedded on one side of the cover.

[0012] Preferably, a plurality of air inlet holes are respectively arranged around the ventilation pipe on the side walls of the cover and the housing.

[0013] Preferably, a hydrophobic membrane is arranged above the spray head.

[0014] Preferably, a fan is arranged above the housing, and the air outlet of the fan is horizontally arranged on one side of it.

[0015] Preferably, a placing seat is arranged at the bottom of the housing, and a silica gel shock pad or a spring damping structure is arranged inside the placing seat.

[0016] According to the above technical solution, the beneficial effect of the present invention compared with the prior art is as follows: When the air in the present application enters the first spiral guide pipe in the ventilation pipe, it rises along a spiral route. During the rising process, the water pump sprays the water source in the water storage tank from the spray holes and the spray head of the spray pipe. The spray head is located above the first spiral guide pipe and can wash and purify the air at the air outlet of the first spiral guide pipe. At the same time, the spray holes on its pipe body can also wash and purify the air in the first spiral guide pipe. The purified air continues to rise until it is discharged, and the purified water flows back into the water storage tank along the first spiral guide pipe; this water-washing purification device extends the air flow path. The spray holes of the spray pipe and the top spray head form an up-and-down cooperative water curtain, and the air can pass through the water curtain for multiple times, improving the purification effect. The purified water flows back to the water storage tank along the inner wall of the spiral guide pipe by natural gravity, without an additional water pump, reducing energy consumption.

[0023] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below with reference to the drawings and specific embodiments.

[0024] Refer to Figures 1-4 : A water-washing air purification device, the device includes: a housing 1, a water storage tank 2, a ventilation pipe 3, a water pump 4, and a spray pipe 5. The water storage tank 2 is arranged at the bottom of the housing 1. The ventilation pipe 3 is arranged above the water storage tank 2, and a first spiral guide pipe 301 is coaxially arranged inside it. The water pump 4 is arranged in the water storage tank 2, and its water outlet is arranged vertically upward. The spray pipe 5 is coaxially and vertically arranged inside the first spiral guide pipe 301, and its water inlet is communicated with the water outlet of the water pump 4. The upper end of the spray pipe 5 extends out of the first spiral guide pipe 301 and is provided with a spray head 502, and a plurality of spray holes 501 adapted to the first spiral guide pipe 301 are arranged at intervals around its pipe body.

[0025] When the air in this application enters the first spiral guide pipe 301 in the ventilation pipe 3, it rises along a spiral route. During the rising process, the water pump 4 sprays the water source in the water storage tank 2 from the spray holes 501 of the spray pipe 5 and the spray heads 502. The spray heads 502 are located above the first spiral guide pipe 301 and can wash and purify the air at the air outlet of the first spiral guide pipe 301. At the same time, the spray holes 501 on its pipe body can also wash and purify the air in the first spiral guide pipe 301. The purified air continues to rise until it is discharged, and the purified water flows back into the water storage tank 2 along the first spiral guide pipe 301; this water washing and purification device extends the air flow path. The spray holes 501 of the spray pipe 5 and the top spray heads 502 form an upper and lower coordinated water curtain, and the air can pass through the water curtain for multiple times, improving the purification effect. The purified water flows back to the water storage tank 2 along the inner wall of the spiral guide pipe by natural gravity, without additional water pumps, reducing energy consumption.

[0026] Refer to Figure 6 : Atomizing nozzles 503 and flat-head atomizing nozzles 504 are respectively arranged at the spray holes 501 and the water outlet holes of the spray heads 502.

[0027] In this application, the atomizing nozzles 503 and the flat-head atomizing nozzles 504 spray water at high speed through narrow outlets, and form a fan-shaped atomized water curtain under the action of air resistance, breaking the water flow into tiny water droplets with a diameter of 10 - 50 μm, greatly increasing the gas-liquid contact surface area.

[0028] Refer to Figure 6 : The water outlet of the flat-head atomizing nozzle 504 is in an arc shape adapted to the spray head 502.

[0029] In this application, the arc-shaped water outlet of the flat-nozzle atomizing nozzle 503 and the circular structure of the spray head 502 form a continuously transitional spraying angle to comprehensively and evenly cover the air flow, improving the purification effect. The fan-shaped water curtain generated by the arc-shaped water outlet forms an orthogonal interference with the spiral rising air flow, enhancing the gas-liquid shear force and promoting the dissolution of pollutants.

[0030] Refer to Figure 4 and Figure 5 : A second spiral guide pipe 201 is coaxially arranged in the water storage tank 2, and a reverse osmosis filter membrane 202 is arranged at the water outlet of the second spiral guide pipe 201.

[0031] During the process of air rising along the first spiral guide pipe 301 in this application, some heavier particles will slide down along the first spiral guide pipe 301 onto the second spiral guide pipe 201 in the water storage tank 2. The purified water flow will also flow back along the inner wall of the first spiral guide pipe 301 onto the second spiral guide pipe 201 in the water storage tank 2. These heavier particles and impurities in the water flow will be intercepted by the reverse osmosis filtration membrane 202. The water flow filtered by the reverse osmosis filtration membrane 202 will pass through the reverse osmosis filtration membrane 202 and flow back into the bottom of the water storage tank 2, and then be pumped out by the water pump 4; because the filtration rate of the reverse osmosis filtration membrane 202 is limited, the second spiral guide pipe 201 can store a certain amount of water flow to facilitate the slow filtration of the reverse osmosis filtration membrane 202. At the same time, the water flow stored in the second spiral guide pipe 201 can exert a certain pressure on the reverse osmosis filtration membrane 202 to create a pressure difference, accelerate the filtration efficiency, and reduce the water change frequency.

[0032] Refer to Figure 2 : A cover 6 is detachably arranged on one side of the housing 1, and a handle 601 is embedded on one side of the cover 6.

[0033] The housing 1 and the cover 6 of this application are connected by elastic buckles, such as ABS plastic buckles. The buckle spacing is 5 - 8 mm, and a pressing stroke of 2 - 3 mm can achieve quick disassembly and assembly; For heavy-duty housings 1, such as those made of stainless steel, a linear slide rail + lock structure is adopted; Neodymium iron boron strong magnets can also be embedded at the edges of the housing 1 and the cover 6, and precise adsorption can be achieved in cooperation with positioning pins, which is suitable for household portable models; The handle 601 is made of a stamping stainless steel sheet with a thickness of 1.5 - 2 mm, and is fixedly embedded on the outside of the cover 6 by laser welding or riveting, so as to facilitate the user to disassemble the cover 6.

[0034] Refer to Figure 2 and Figure 3 : A number of air inlet holes 101 are respectively arranged around the ventilation pipe 3 on the side walls of the cover 6 and the housing 1.

[0035] The air inlet holes 101 in this application are annularly distributed along the side wall of the ventilation pipe 3 to form 360° surrounding air intake, improving the air intake volume and purification efficiency.

[0036] Refer to Figure 3 : A hydrophobic membrane 102 is arranged above the spray head 502.

[0037] Through this design in this application, it is ensured that the air flow cannot carry water droplets through, so as to ensure that the water droplets can flow back into the water storage tank 2 through the first spiral guide pipe 301 and the second spiral guide pipe 201, improving the water circulation rate and reducing the water addition and water change frequencies.

[0038] Refer to Figure 1: The blower 7 is arranged above the housing 1, and the air outlet of the blower 7 is horizontally arranged on one side thereof.

[0039] With this design, the present application can convey clean air in a directional manner to reduce the clean air re-entering the device and improve the purification efficiency.

[0040] Refer to Figure 2 and Figure 3 : A placement seat 103 is arranged at the bottom of the housing 1, and a silica gel shock pad or a spring damping structure is built in the placement seat 103.

[0041] The placement seat 103 of the present application increases the bottom contact area, lowers the center of gravity of the device, and prevents the risk of tipping caused by the high-speed operation of the blower 7; a silica gel shock pad or a spring damping structure is built in the placement seat 103 to absorb the vibration during the operation of the blower 7 and the water pump, and the system noise is reduced from 45 dB in the traditional design to 28 dB; rubber anti-slip patterns are integrated at the bottom of the placement seat 103 to prevent the device from sliding.

[0042] When the air enters the first spiral diversion pipe 301 in the ventilation pipe 3 in the device provided by the present invention, it rises along a spiral route. During the rising process, the water pump 4 sprays the water source in the water storage tank 2 from the spray holes 501 and the spray heads 502 of the spray pipe 5. The spray head 502 is located above the first spiral diversion pipe 301 and can wash and purify the air at the air outlet of the first spiral diversion pipe 301. At the same time, the spray holes 501 on its pipe body can also wash and purify the air in the first spiral diversion pipe 301. The purified air continues to rise until it is discharged, and the purified water flows back into the water storage tank 2 along the first spiral diversion pipe 301; this water washing and purification device extends the air flow path. The spray holes 501 of the spray pipe 5 and the top spray head 502 form an up-and-down coordinated water curtain, and the air can pass through the water curtain for multiple times, improving the purification effect. The purified water flows back to the water storage tank 2 by natural gravity along the inner wall of the spiral diversion pipe without an additional water pump, reducing energy consumption.
