Description

Air purifier and air purifying method

Technical Field

The invention relates to the field of air purification, in particular to an air purifier and an air purification method.

Background

With the continuous forward development of the social and economic level, the requirements of people on the quality of life are increasingly improved, and the people pay more attention to the living environment. In recent years, the continuous air pollution event greatly promotes the public demand and understanding of the air purifier, so that the air purifier products begin to be popularized gradually. Air purification mainly refers to removing particles and fine dust in air.

The existing methods for removing particles and dust in air mainly comprise several methods: sieve method, cyclone method and electrostatic method. The screen method is to allow air to pass through various high-efficiency particle air filters of different levels and a screen consisting of carbon particles, etc., so as to block dust particles. The electrostatic method ionizes gas by a strong electric field to charge and adsorb dust particles on an electrode plate. The cyclone separation method is to accelerate the airflow by a high-speed centrifugal fan and separate dust particles in the air by a cyclone separator.

The filter screen method has the disadvantages of high cost due to the need of replacing consumables regularly. Ionization methods produce ozone, which is harmful to the human body, and may also discharge electricity, creating a hazard. Cyclone separation has a large pressure loss, which requires a fan to generate a large pressure rise, which is disadvantageous to noise and volume, and at the same time, the filterable flow rate is small and the purification speed is extremely slow.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, unless specified to the contrary, use of the terms of orientation such as "upper, lower, top, bottom" or the like are generally described with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, or gravitational direction. The "lateral direction" refers to a lateral direction of the air purifier in a state where the air purifier is placed in normal use. "upstream, downstream" is with respect to the direction of air flow in the air purifier.

The prior art air purifier usually adopts several methods, such as a screen method, a cyclone separation method and an electrostatic method, to remove particles and dust in the air. Among other things, the screen method has the disadvantage of requiring periodic replacement of consumables (e.g., screens) at high cost. The ionization method can generate ozone which is harmful to human bodies and can also discharge electricity to generate danger, and greater potential safety hazards exist. Cyclone separation has a large pressure loss, which requires a fan to generate a large pressure rise, which is disadvantageous to noise and volume, and at the same time, the filterable flow rate is small and the purification speed is extremely slow.

Accordingly, the present invention provides an air purifier. Referring specifically to fig. 1 to 6, an air purifier according to a preferred embodiment of the present invention is shown. Wherein, this air purifier includes the inlet chamber 1 and the mixed clean room 2 of adjacent setting, and inlet chamber 1 is equipped with inlet chamber entry 11 and inlet chamber export, and the inlet chamber export communicates in mixed clean room 2, mixes clean room 2 including atomizer 21, with a plurality of separation plates 22 that the inlet chamber export set up relatively and set up at the clean air export 23 on mixed clean room 2 lateral wall upper portion, atomizer 21 sets up between inlet chamber export and separation plate 22, and is located the upstream position of separation plate 22.

The air purifier is divided into the air inlet chamber 1 and the mixed purification chamber 2, so that water and electric devices (such as a fan, a water pump and the like) are completely separated, and the condition of high-voltage discharge cannot occur. By arranging the atomizer 21 in the mixing and purifying chamber 2, the atomizer 21 atomizes water and then mixes the atomized water with air flowing out from the outlet of the air inlet chamber, and compared with the contact and mixing of air and water columns in the prior art, dust particles in the air are more easily captured by the atomized water; and because a plurality of separation plates 22 are arranged at the downstream of the atomizer 21 along the flowing direction of the airflow, the air mixed with the water is separated and purified again through the plurality of separation plates 22, so that the purification efficiency of the air purifier is improved. The air purifier of the invention does not need consumables, only needs to replace water, and can not generate ozone and the like harmful to human bodies because only water is used as a filter medium, thereby improving the use safety and reliability of the air purifier.

Meanwhile, the atomizer 21 atomizes the water into water mist, so that compared with directly spraying water columns, the resistance in the mixing purification chamber 2 is smaller, namely, dust particles in the air are mixed with the atomized water and continue to flow along with the air flow, and thus, the purification efficiency is improved.

In a preferred embodiment of the present invention, referring to fig. 1 to 6, an inlet chamber 1 and a mixing and purifying chamber 2 are sequentially arranged in a lateral direction of an air purifier. However, the present invention is not limited thereto, and the intake chamber 1 and the mixing and purifying chamber 2 may be sequentially arranged in the longitudinal direction of the air cleaner, and the intake chamber 1 and the mixing and purifying chamber 2 may be disposed at an angle. The following embodiments are described by way of example in which the inlet chamber 1 and the mixing chamber 2 are arranged in order in the transverse direction of the air cleaner.

In one embodiment of the present invention, the air intake chamber 1 and the mixed purification chamber 2 of the air purifier are of a split structure, that is, the air intake chamber 1 and the mixed purification chamber 2 are independent chambers, and the air intake chamber 1 and the mixed purification chamber 2 are in sealed communication through an air intake pipe. Especially, the above-mentioned split structure can be adopted in the case that the size of the outlet of the air intake chamber 1 is greatly different from the size of the air intake port of the mixing purification chamber 2. In particular, the air inlet cover of the mixing and purifying chamber 2 is provided with a partition 12 of a plurality of first through holes 121. Because the air inlet of the mixing purification chamber 2 is of a small hole type, air can uniformly and flatly enter and is combined with atomized water, and the purification efficiency of the air purifier is improved.

However, in the preferred embodiment of the present invention, in order to make the structure of the air cleaner more compact and simple, in particular, the air cleaner includes an integrated chamber, which is divided into the intake chamber 1 and the mixing and purifying chamber 2 by the partition plate 12 perpendicular to the lateral direction and disposed with the plurality of first through holes 121, the plurality of first through holes 121 being the intake chamber outlet. Referring specifically to fig. 3 and 6, the partition 12 divides the integrated chamber of the air cleaner into an intake chamber 1 and a mixing and purifying chamber 2. The air uniformly flows into the mixing and purifying chamber 2 through the first through hole 121, so that the air is mixed with the water atomized by the atomizer 21, and the purifying efficiency of the air purifier is improved. The partition plate 12 is fully provided with a plurality of first through holes 121 to directly block large impurities in the air inlet chamber 1.

Preferably, the first through hole 121 of the partition plate 12 is a circular hole, and the diameter of the first through hole 121 is 3mm to 15 mm. It should be understood by those skilled in the art that the first through hole 121 may have other shapes (e.g., rectangular, triangular, oval, etc.) and sizes.

Specifically, referring to fig. 6 to 8, the separation plate 22 includes a frame 221 having a second through hole 225 and a gauze 222, and the gauze 222 is fixedly covered on the second through hole 225. Atomized water drops spontaneously form a water film on the gauze 222, so that water mist can be left in the mixed purification chamber 2, and the humidity of indoor air is prevented from being increased due to the fact that a large amount of water vapor overflows. Wherein the mesh number of the gauze 222 is preferably not less than 40 mesh. The atomisers are directed towards the outlet of the inlet chamber and the separating plate 22, respectively, so that the atomised water spontaneously adheres to the gauze 222 of the separating plate 22 to form a water film, which breaks when the pressure of the air flow is greater than the tension of the water film, the air flow passes through the gauze 222, and the water flows down along the gauze 222 or splashes onto the gauze 222 of the downstream separating plate 22, during which the dust particles which have not been captured in the preceding process are collected again. The condensation of water droplets on the separator plate 22 slides down the screen 222, causing the water and air flow to separate again. Therefore, by repeating the above process, the air flow is filtered through the plurality of separation plates 22, and the filtered air is discharged through the purified air outlet 23 to obtain clean air.

In a preferred embodiment of the present invention, referring to fig. 6 to 8, the separation plate 22 includes first separation plates 223 arranged in parallel in sequence along the lateral direction, and the area of the second through holes 225 occupies 80 to 90% of the total area of the first separation plates 223, i.e., the second through holes 225 are distributed almost throughout the first separation plates 223 to form the frame 221. Wherein at least two first separation plates 223 are sequentially arranged in parallel in the transverse direction in the hybrid purification chamber 2. To ensure that the dust particles in the air are adequately collected and captured.

In order to increase the flow path of the air flow to ensure sufficient collection and catching of the air flow, it is more preferable that the separation plate 22 further includes a second separation plate 224, the second separation plate 224 is located at one side of the first separation plate 223 and is laterally closest to the purified air outlet 23, the second penetration hole 225 is located at a lower portion of the second separation plate 224, and the area of the second penetration hole 225 occupies 40 to 60% of the total area of the second separation plate 224. That is, the upper portion of the second separation plate 224 is a solid flat plate, and the second through holes 225 are provided only in the lower portion of the second separation plate 224, so that the air flow flows out only from the gauze 222 of the lower second through holes 225.

In the air flow mixed with the mist, most of the atomized water droplets are coagulated on the first separating plate 223 and slide down along the gauze 222, and the air flow passes through the gauze 222 on the first separating plate 223. After the air stream mixed with the water mist passes through the plurality of first separation plates 223, only a small portion of the atomized water droplets are present. The small atomized water droplets coalesce and slide off the upper solid flat plate of the second separator plate 224 and the gas stream exits the lower screen 222. Where the airflow makes a first turn. Since the purified air outlet 23 is provided at the upper portion of the side wall of the mixing and purifying chamber 2, the air flow flowing out of the gauze 222 at the lower portion flows upward again and is discharged from the purified air outlet 23. Where the airflow makes a second turn. Preferably, the purified air outlet 23 is fixedly sealed with a water absorbing medium 25, and preferably, the water absorbing medium 25 is a sponge. When the air flow from the lower gauze 222 passes through the water absorbing medium 25, the water absorbing medium 25 can sufficiently absorb the moisture in the air flow from the lower gauze 222 to discharge dry (or appropriate humidity) and clean air to the outside.

Preferably, a plurality of second separating plates 224 may be disposed between the first separating plate 223 and the purified air outlet 23, such that a sequentially bent air flow path is formed to extend a circulation time of the air flow, such that dust particles in the air are effectively separated to obtain clean air.

In order to further enable the air purifier to be energy-saving and environment-friendly, the air purifier further comprises a water pump, and a pipeline inlet 3 and a water outlet 4 which are respectively positioned on the mixing purification chamber 2, wherein a water outlet of the water pump is hermetically connected with the pipeline inlet 3 through a pipeline, the pipeline inlet 3 is hermetically connected with the atomizer 21 through a pipeline, and a water inlet of the water pump is hermetically connected with the water outlet 4 through a pipeline. Clean water passes through water pump through pipeline entry 3, and the pump sending is to atomizer 21, and atomizer 21 atomizes the clean water of pump sending to mix with the dirt particle in the air, discharge by outlet 4 again, the water that has the dirt particle after the discharge is through purifying the back, and the rethread gets into the water inlet of water pump, makes the water after the purification pass through water pump through pipeline entry 3 once more, and the pump sending is to atomizer 21, in order to realize the cyclic utilization of water. Wherein the water pump is operative to provide sufficient pressure to cause the atomiser 21 to eject water having sufficiently fine particles.

In a preferred embodiment of the invention, referring to fig. 1 to 6, a pipe inlet 3 and a drain 4 are provided at the top and bottom of the mixing and purifying chamber 2, respectively, so that water can flow downward to be discharged by gravity. However, the present invention is not limited thereto, and the pipe inlet 3 and the drain 4 may be provided on the side wall of the mixing and purifying chamber 2.

Preferably, a filter device is arranged between the water inlet and the water outlet 4 of the water pump. Sundries in water discharged from the water outlet 4 are separated through the filtering device, so that the filtered clean water is pumped to the atomizer 21 through the water pump again to be recycled, the waste of water resources is reduced, and the purposes of energy conservation and environmental protection are achieved.

It should be noted that, due to the structure of the separation plate 22, the separation plate 22 can be reused, and after a period of use, the separation plate 22 can be cleaned to be reused. Therefore, in the preferred embodiment of the present invention, referring to fig. 6, the mixing and purifying chamber 2 is provided with a guide rail 24, and the atomizer 21 and the plurality of separation plates 22 are mounted on the guide rail 24 and can move back and forth along the guide rail 24. Wherein the guide rails 24 serve to position the atomizer 21 and the plurality of separation plates 22. At the same time, the atomizer 21 and the plurality of separation plates 22 can move back and forth along the guide rail 24 due to the presence of the guide rail 24. So that the atomized amount of water is changed when the gear of the air cleaner is adjusted (i.e., to adapt to different cleaning conditions), the distance between the atomizer 21 and the separation plate 22 may be changed along the guide rail 24 to form a water film on the separation plate 22 better.

In the preferred embodiment of the present invention, the guide rail 24 is provided on the inner bottom surface of the mixing and purifying chamber 2, and thus, referring to fig. 7 and 8, the bottom outer circumference of the separating plate 22 is provided with a groove 241 which is engaged with the guide rail 24. Of course, the present invention is not limited thereto, and the guide rail 24 may be provided on the inner side of the hybrid purification chamber 2 or both the inner side and the bottom of the hybrid purification chamber 2, and accordingly, the outer circumferences of the sides or the outer circumferences of the bottom and the sides of the separation plate 22 are provided with the grooves 241 which are engaged with the guide rail 24. In addition to the above-described functions, the guide rail 24 also facilitates the mounting and dismounting of the separation plate 22. It will of course be appreciated by those skilled in the art that the bottom peripheral edge of the separator plate 22 is provided with other structures to interact with the guide rail 24. For example, the guide rail 24 may be at least two guide rails 24 arranged in parallel in the lateral direction. The bottom outer periphery of the separating plate 22 is provided with a projection which is fitted into a space between two adjacent guide rails 24. When the separation plate 22 needs to be cleaned or is cleaned, the separation plate 22 is simply pulled out or replaced along the guide rail 24.

Preferably, the guide rail 24 is provided with locking means for fixing the atomizer 21 and the plurality of separation plates 22. For example, a plurality of protrusions or elastic pads may be provided on the side of the guide rail 24 at intervals to increase the friction coefficient of the atomizer 21 and the plurality of separation plates 22 with the side of the guide rail 24, respectively, to fix the atomizer 21 and the plurality of separation plates 22. It will of course be appreciated by those skilled in the art that locking means may also be provided on the atomiser 21 and the plurality of separating plates 22.

Preferably, the atomizer 21 includes a mounting bracket 211 and an atomizer head disposed on the mounting bracket 211, and the mounting bracket 211 is mounted on the guide rail 24 and can move back and forth along the guide rail 24. Wherein the mounting bracket 211 may also have the same structure as the structure in which the separation plate 22 and the same guide rail 24 are fitted to each other.

So that the water mist sprayed by the atomizing nozzles can be spread over substantially the entire mixing and purifying chamber 2. Of course, the present invention is not limited to this, and the atomizer 21 may include an atomizer rotating 360 ° or 180 ° around the mounting bracket 211, and may also include an atomizer spraying water mist 360 ° or 180 ° at the same time. Preferably, the particle diameter of the water drops sprayed by the atomizing nozzle does not exceed 100 mu m.

In order to efficiently capture the air with dust particles, a fan is preferably connected to the inlet 11 of the inlet chamber. Air is drawn into the intake chamber 1 by a blower. And the fan sets up in the air inlet chamber of 1 entry 11 department to separately water and fan, need not consider the waterproof of fan, also avoid appearing taking place the condition emergence of high-voltage discharge, further improved air purifier's safe in utilization reliability.

The invention also provides an air purification method, which utilizes the air purifier, and the air purification method comprises the following steps:

first, water is atomized by the atomizer 21 so that the atomized water is mixed with dust particles in the air; wherein, the air is combined with the water mist instead of being contacted with the traditional water column, thereby leading dust particles in the air to be captured by the atomized water more easily and leading the purification effect to be better.

The air mixed with the atomized water then passes sequentially through a plurality of separation plates 22 to separate the water and dust particles mixed with the water from the air. The air mixed with the atomized water spontaneously forms a water film on the separating plate 22, so that part of water drops are adhered to the wall surface of the separating plate 22 and slide down, the air and part of water drops pass through the separating plate 22 and fall onto the adjacent downstream separating plate 22, and the actions are repeated, namely the air mixed with the atomized water sequentially passes through the plurality of separating plates 22, so that the water and dust particles mixed with the water are fully separated from the air, and clean air is obtained.

The operation principle and path of the air purifier of the present invention will be described with reference to fig. 1 to 8.

When the air purifier works, the fan blows air into the inlet 11 of the air inlet chamber, then enters the air inlet chamber 1, enters the mixing purification chamber 2 through the outlet of the air inlet chamber, and the outlet of the air inlet chamber (namely, the first through hole 121 of the partition plate 12) enables the air flow to be divided into a plurality of strands to flow out, so that the air flow and the water mist atomized by the atomizer 21 can be fully contacted and mixed. The first atomizing nozzle 212 sprays the water mist in the direction opposite to the air flow, the relative speed of the atomized water droplets and the air flow is high, and dust particles in the air flow are combined with the water droplets more easily. The second atomizer 213 sprays atomized water droplets in the same direction as the air flow, and the atomized water droplets are mixed with the water droplets from the first atomizer 212 and form a water film on the first separating plate 223. Part of the water drops adhere to the wall surface and slide down, and part of the water drops reach the first separation plate 223 along the airflow direction, a water film is formed on the gauze 222 of the first separation plate 223 in an adhesion mode, when the airflow pressure is larger than the tension of the water film, the water film breaks the airflow and passes through the gauze 222, and the water flows downwards along the gauze 222 or splashes on the adjacent downstream first separation plate 223 or second separation plate 224. Dust particles that have not been captured in the preceding process are collected again. The condensation of water droplets on the first separator plate 223 slides down the screen 222, allowing water and air to be separated again. The upper part of the second separating plate 224 is a solid flat plate and the lower part is a gauze 222, so that the airflow is turned, the escaped partial water mist is condensed and slides on the upper solid flat plate of the second separating plate 224, and the airflow flows out of the gauze 222 at the lower part. The outgoing air flow passes a turn again and flows back into the air through the sponge of the purified air outlet 23, so that the outgoing air is less humid.
