Technical Field

[0001] The present invention relates to the technical field of air purification equipment, in particular to an air purification system. Background Art

[0002] Air purification equipment includes fume purifiers, which can filter out or kill air pollutants and effectively improve air cleanliness. They are mainly household and commercial air purification equipment that removes indoor air pollution. Air purification equipment can filter pollutants such as airborne particulate matter, bacteria, viruses, fungal spores, pollen, asbestos, and fume products.

[0003] Most existing air purification equipment uses filter plates or activated carbon and other filter structures to filter pollutants inside the air. However, there are gaps inside the filter plates or activated carbon and other filter structures. When the air passes through these filter structures, the pollutants in the air are not completely filtered out. The pollutants in the air will still pollute the external environment, and the deodorization effect is even worse. Therefore, there is a need for filter equipment that can completely filter pollutants in the air and remove odors. Summary of the invention

[0004] The object of the present invention is to provide an air purification system to solve the problems raised in the above background technology.

After that, the air to be purified can enter the purification chamber from the air inlet of the machine body, and when passing through the mounting groove, it can contact with the foam generated on the horizontal plate, thereby achieving the effect of air purification and deodorization; in addition, in another scheme, the purification liquid can be directly discharged from the small holes under the action of air pressure, so that foam can also be formed on the surface of the horizontal plate.

[0010] By adopting the above technical scheme, it is mainly possible to provide the foam generating component with a source of purified liquid and high-pressure air, wherein the purified liquid can be discharged from the liquid through hole of the liquid through pipe, thereby forming a thin film on the horizontal plate to provide the purified liquid, and the high-pressure air can first enter the cavity and then be blown out from the small holes of the horizontal plate, thereby blowing the purified liquid into foam and completing the generation of foam; the base frame serves as the main component of the foam generating component, and can connect the liquid through pipe and the horizontal plate, so that the three form an integral structure.

[0011] Preferably, a ventilation pipe is installed on the base frame, and the ventilation pipe is connected to the cavity.

[0012] By adopting the above technical solution, the ventilation pipe is used to connect the air source pipeline, so that high-pressure air is introduced into the ventilation pipe, then enters the cavity, and finally is output from the small hole.

[0013] Preferably, it also includes: The air compressor is connected to the vent pipe through a pipeline and is configured to provide compressed air and introduce the compressed air into the vent pipe.

[0014] By adopting the above technical solution, the supply of high-pressure air is achieved through an air compressor.

[0015] Preferably, it also includes: A liquid storage tank, configured to store purified liquid, the liquid storage tank being connected to the liquid passage pipe via a pipeline; The throttle valve is connected to the pipeline between the liquid storage tank and the liquid pipe.

[0016] By adopting the above technical solution, the purified liquid can be stored in the liquid storage tank, and a pump body is installed on the pipeline between the liquid storage tank and the liquid pipe. When needed, the purified liquid can be introduced from the liquid storage tank into the liquid pipe, and finally the purified liquid is placed on the surface of the horizontal plate; the throttle valve provided can control the flow rate and pressure of the purified liquid, and is used to evenly distribute the liquid in different liquid pipes.

[0017] Preferably, there are a plurality of small holes which are evenly distributed on the surface of the horizontal plate.

[0018] By adopting the above technical solution, the purification liquid on the horizontal plate can be foamed evenly to increase the density of the foam generated by the purification liquid, thereby increasing the contact area with the air to be purified.

[0029] Compared with the prior art, the present invention has at least one of the following beneficial effects: The present invention adopts a method of setting multiple small holes on the horizontal plate, so that the purification liquid forms purification foam on the surface of the horizontal plate, so that the air to be purified comes into contact with the foam when passing through, and pollutants in the air are removed, preventing the pollutants in the air from polluting the external environment.

[0030] In the present invention, since the liquid through holes are arranged at equal intervals on the liquid through tube, and a plurality of small holes are arranged at equal intervals on the horizontal plate, the purified solution in the liquid through tube can be evenly spread on the top of the horizontal plate through the liquid through holes.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1-8 The present invention provides an embodiment: an air purification system, comprising a body 1, a mounting frame 2 and a foam generating component 3. Among them: The body 1 is provided with a purification chamber 102 therein, and is provided with an air inlet 101 and an air outlet 103 which can be communicated with the purification chamber 102, wherein the air inlet 101 is used to allow the air to be purified to enter the body 1, and the air outlet 103 is used to allow the purified gas to be discharged therefrom.

[0038] The mounting frame 2 is installed in the purification chamber 102 of the body 1, and a mounting groove 205 is provided inside the mounting frame 2. Specifically, the mounting frame 2 includes a bottom frame 201 and a top frame 202, and a plurality of columns 203 are installed between the bottom frame 201 and the top frame 202. Partitions 204 are installed on the columns 203, and a mounting groove 205 is formed between two upper and lower adjacent partitions 204. A guard plate 206 with a Z-shaped cross-section is also installed above the partition 204. At least one group of the mounting frame 2 is provided in the purification chamber 102. In this example, two groups of the mounting frame 2 are provided in the purification chamber 102 to better achieve the effects of air purification and deodorization.

[0039] The foam generating assembly 3 is movably mounted in the mounting groove 205, and includes a horizontal plate 301, on which small holes 302 are provided. The small holes 302 are multiple in number and are evenly distributed on the surface of the horizontal plate 301. The purified liquid can be discharged from the small holes 302 from bottom to top, so that foam is formed on the surface of the horizontal plate.

[0040] In this example, the foam generating component 3 includes a main body 309 which is hollow inside, the top wall of the main body 309 is a horizontal plate 301, the small hole 302 is connected to the internal cavity of the main body 309, and the main body 309 is equipped with a liquid passing pipe and a ventilation pipe which are connected to the hollow cavity. Specifically, the liquid passing pipe is a first liquid passing pipe 310, and the ventilation pipe is a first ventilation pipe 311. During operation, the purified liquid can first enter the inner cavity of the main body 309 through the liquid passing pipe, and then the compressed air enters the cavity of the main body 309 through the ventilation pipe, and finally is discharged from the small hole 302. In the process of being discharged from the small hole 302, part of the purified liquid can also be discharged at the same time, thereby forming foam on the surface of the horizontal plate 301. These foams are used to achieve air purification and deodorization.

[0041] In another embodiment, the horizontal plate 301 is concavely arranged on the surface of the main body 309, that is, the horizontal plate 301 is surrounded by a retaining structure higher than its upper surface, which can limit the foam from flowing downward.

[0042] Specifically, it also includes: an air compressor connected to the vent pipe via a pipeline and configured to provide compressed air and introduce the compressed air into the vent pipe; Specifically, it also includes: A liquid storage tank is configured to store the purification liquid. The liquid storage tank is connected to the liquid pipe through a pipeline. A pump body is connected to the pipeline between the liquid storage tank and the liquid pipe, and the purification liquid can be introduced into the liquid pipe during operation. The purification liquid can be water and a foaming agent, or a disinfectant, or other corresponding chemical solutions with purification functions. The throttle valve 6 is connected to the pipeline between the liquid storage tank and the liquid pipes. After the pump body is working, the throttle valve 6 can be used to achieve the effect of uniform liquid separation in different liquid pipes.

[0043] In one embodiment, the entire air purification system is equipped with an air compressor and a liquid storage tank. An air compressor is connected to multiple pipes to introduce compressed air into the cavity to provide the compressed air required for operation; a liquid storage tank is also connected to multiple pipes to introduce purified liquid into different second liquid pipes 304 to achieve the supply of purified liquid, wherein the pump body is used to provide a power source for the flow of purified liquid, and the throttle valve is used to achieve uniform liquid separation in different second liquid pipes 304.

[0044] In addition, in another embodiment, each foam generating component can be equipped with an air compressor and a liquid storage tank to achieve separate control of a single foam generating component. The operation of the corresponding foam generating component can be controlled according to actual needs, which is more flexible to use.

[0045] In addition, the air compressor and the liquid storage tank can be installed on the machine body 1, or arranged outside the machine body 1, and their placement positions are not limited here.

[0046] Specifically, an induced draft component 4 is installed at the air outlet 103 of the body 1. In this example, the induced draft component 4 is a fan, which is arranged at the air outlet 103 of the body 1, that is, the purified air is allowed to enter the body 1 by induced draft, and then discharged after purification to achieve circulation.

[0047] Specifically, a filter plate 5 is installed at the air inlet 101 of the body 1. The filter plate 5 can adopt activated carbon or other plate-type filter devices in the prior art, which is mainly used to filter solid particles in the air, and then use foam to filter the air to achieve a better deodorization effect.

[0048] Specifically, the foam generating components 3 are stacked on the mounting frame 2 , and a gap is formed between two adjacent groups of foam generating components 3 , and the gap is connected to the purification chamber 102 .

[0049] Embodiment 2

[0050] like Figure 9-11 As shown, the difference between this embodiment and the above embodiment is that the foam generating component 3 includes: The base frame 303 is a shell-type structure with an open top surface, and the horizontal plate 301 is installed in the middle position inside the frame; A liquid passage pipe (in this example, the liquid passage pipe is the second liquid passage pipe 304), which is fixed to the inner side of the base frame 303, and a plurality of liquid passage holes 305 are opened on the side wall of the liquid passage pipe close to the horizontal plate 301, and the lowest point of the liquid passage hole 305 is higher than the upper surface of the horizontal plate 301; A cavity 306 is formed between the base frame 303 , the liquid passage pipe and the horizontal plate 301 .

[0051] Among them, the purification liquid can be placed on the surface of the horizontal plate 301. When the air is blown out from the small hole 302, the purification liquid can be blown and foam can be formed on the surface of the horizontal plate 301. The air to be purified can enter the purification chamber 102 from the air inlet 101 of the body 1 and contact with the foam. After the air to be purified is deodorized and purified, it is discharged from the air outlet 103.

[0052] More specifically, in this example, there are two second liquid-passing pipes 304, which are respectively located on both sides of the base frame 303, so that the purified liquid can be introduced into the surface of the horizontal plate 301 more quickly during operation. In this example, the base frame 303, the second liquid-passing pipe 304 and the horizontal plate 301 are welded to each other. After the welding is completed, a receiving cavity 308 is formed above the foam generating assembly 3, that is, the uppermost ends of the second liquid-passing pipe 304 and the base frame 303 are higher than the upper plane of the horizontal plate 301, so that the purified liquid on the horizontal plate 301 can be blocked to a certain extent to prevent the purified liquid from flowing downward.

[0053] Specifically, a ventilation pipe (in this example, the ventilation pipe is the second ventilation pipe 307 ) is installed on the base frame 303 , and the ventilation pipe is connected to the cavity 306 . The ventilation pipe is installed in the middle position of the base frame 303 , and multiple ventilation pipes may be provided according to actual conditions.

[0054] When this air purification system is in use, the air to be purified enters the purification chamber 102 of the machine body 1 under the action of the air induction component 4. At the same time, the purified liquid first flows out from the second liquid pipe 304 and the liquid hole 305, flows to the surface of the horizontal plate 301 and forms a thin film, and then the high-pressure air is introduced into the cavity 306 from the second ventilation pipe 307, and finally guided upward from the small hole 302 on the surface of the horizontal plate 301, so that the thin film liquid forms foam on the surface of the horizontal plate 301 under the action of the high-pressure air. After the air to be purified flows through the space above the horizontal plate 301 and contacts with the foam, the air purification function can be achieved, and the impurities and odors in the air can be removed.

[0055] The following table compares the purification data of different pollutants between the existing air purifier and the bubbling air purifier (the air purification system described in the above two embodiments) in the case of a kitchen as the usage scenario:

[0056] From the above table, it can be seen that the purification rate of the air purifier in the prior art for PM2.5 in the air is 87%-90%, while the purification rate of the bubble air purifier in this example for PM2.5 in the air with inhalable particles is 90%-95%; The existing air purifiers can purify 90%-93% of the oil smoke in the air, while the bubbling air purifier can purify 92%-98% of the oil smoke in the air. The existing air purifiers have a purification rate of 60%-65% for non-methane hydrocarbons in the air, while the bubble air purifier has a purification rate of 88%-94% for harmful gases in the air; And existing air purifiers can remove 60% of odors, while bubbling air purifiers can remove 99% of odors.

[0057] In summary, compared with the existing air purifiers, the bubbling method adopted in this embodiment has better deodorizing and purifying effects on kitchen air.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
