Description

Technical Field

[0001] The invention relates to a water air purifier, belonging to the technical field of air purifiers. Background Art

[0002] Air purifiers in the prior art are generally dry purifiers, which have a clearing effect on harmful gases in the air, but require regular replacement of filter elements, which is costly and not environmentally friendly.

[0003] Existing wet air purifiers generally use water curtain or spray type to filter the air. Both types of products have problems such as insufficient specific surface area of ​​water, insufficient contact time between water and air, and excessive humidity of the exhausted air. Summary of the invention

[0004] The purpose of the present invention is to provide a water air purifier, which uses water as a purification medium, does not need to replace the filter element, saves costs and is environmentally friendly; at the same time, the contact time between air and water is increased and the humidity of the exhaust air is reduced.

[0005] The present invention adopts the following technical solutions:

[0006] A water air purifier comprises a water tank 1, a water pump 3, an upper water pipe 11, a water sprinkling chamber 15, an outer frame 12, and a fan; the outer frame is arranged above the water tank 1 and is connected to the water tank 1; the outer frame 12 contains a filler, and the filler is a compressed mesh structure of a non-absorbent flexible material; an air inlet and an air outlet are provided on the outer frame; the water pump 3 draws water from the water tank and pumps it to the water sprinkling chamber 15 through the upper water pipe 11, and the water sprinkling chamber sprays the filler below; the fan is connected to the air outlet on the outer frame.

[0007] This technical solution uses water as the filtering medium, and utilizes the fact that water can absorb PM2.5 and that formaldehyde is soluble in water. Water is pumped into the water sprinkling cavity in the outer frame, and the water is dispersed into a number of water droplets through the water outlet holes in the water sprinkling cavity and flows downward into the filler with a mesh structure of non-absorbent flexible material. The water droplets are separated again by the filler and become a number of tiny water droplets. The tiny water droplets at this time increase the specific surface area. When the airflow passes through the filler, the air can come into contact with the water more fully, thereby enhancing the ability of water to purify the air, while also having less impact on the air humidity.

[0008] Furthermore, the outer frame 12 is a rigid mesh structure; and the fan is a centrifugal fan 19 .

[0009] Furthermore, the upper end of the water tank 1 is assembled and connected to the water tank cover 5, and the water pump 3 is connected to the water tank cover 5.

[0010] Furthermore, an electronic float 4 and an LED germicidal lamp 9 are provided in the water tank, and the electronic float 4 and the germicidal lamp 9 are fixed on the water tank cover 5 .

[0011] Furthermore, the water tank cover 5 is provided with a water inlet 6 and a water outlet 7, the water inlet is used to be connected to an external water source, and the water outlet is used to be connected to a drainage device.

[0012] Furthermore, the bottom surface of the water sprinkling chamber 15 has 200-300 small holes with a diameter of 2.5 mm, and the flow rate is 20 L / min.

[0013] Furthermore, a water sprinkling chamber sealing cover 13 is provided on the upper part of the water sprinkling chamber 15 , the water sprinkling chamber sealing cover 13 is connected to the outer frame 12 , and a ventilating port for communicating with the centrifugal fan 19 above is provided in the water sprinkling chamber sealing cover 13 .

[0014] Furthermore, the outer frame 12 has air inlets on all four sides.

[0015] Furthermore, the filler is an LDPE mesh filler 10.

[0016] Furthermore, the LDPE mesh filler 10 is made by weaving 0.2 mm diameter LDPE material into a mesh, with a mesh-to-wire diameter ratio of 1:1, and the LDPE mesh is compressed to one eighth to one fifteenth of the volume to fill the cavity of the outer frame 12 .

[0017] Furthermore, the water pump 3 is arranged inside the water tank.

[0018] The beneficial effects of the present invention are:

[0019] 1) The water droplets are separated again through the LDPE mesh filler and become several tiny water droplets. The tiny water droplets at this time increase the specific surface area. When the airflow passes through the LDPE mesh filler, the air can contact with the water more fully, thereby enhancing the ability of water to purify the air.

[0020] 2) Using LDPE mesh filler as a water separator is to weave 0.2mm diameter LDPE material into a mesh with a mesh to wire diameter ratio of 1:1, and compress the LDPE mesh to one eighth to one fifteenth of the volume, so that the density of the LDPE mesh is increased, the water flow channels are increased, and the specific surface area of ​​the water is increased.

[0021] 3) The filter medium is municipal tap water or purified water, without adding any toxic or harmful substances, and the raw water is replaced regularly, without consuming other materials, thus avoiding the burden of environmental pollution and saving the cost of use.

[0022] 4) Compared with the existing water air purifiers that filter air in the form of water curtain or spray, the specific surface area is greatly improved, and the water circulates rapidly at a very large flow rate of 20L / min, which greatly increases the contact time between water and air, improves the purification efficiency, and solves the problem of excessive humidity in the exhaust air.

The water tank cover 5 is assembled and connected with the water tank 1, and the electronic float 4 and the LED germicidal lamp 9 are fixed. The water inlet 6 is set on the water tank cover 5 for connecting to an external water source. The water outlet 7 is set on the water tank cover for discharging the dirty water filtered in the water tank; the joint connects the water inlet and outlet. The LED germicidal lamp 9 is fixed on the water tank cover 5. The water inlet of the upper water pipe 11 is connected to the water outlet of the water pump, and the water outlet of the upper water pipe 11 is connected to the water inlet of the water sprinkling chamber 15 in the outer frame 12. The outer frame 12 is connected to the water tank cover 5, and the LDPE mesh filler 10 is filled inside. The top is provided with a water sprinkling chamber 15, and the inner bottom surface of the water sprinkling chamber 15 has a plurality of small holes. The water sprinkling chamber sealing cover 13 is connected to the outer frame 12, and a vent is provided inside, and a centrifugal fan 19 is provided at the top. The water pump 3 can be placed inside or outside the water tank, and its function is to drive the water flow circulation. There are 200-300 small holes with a diameter of 2.5 mm in the water sprinkling cavity, and the flow rate is 20 L / min.

[0030] Continue to see Figure 1The LDPE mesh filler 10 is a mesh made of 0.2 mm LDPE material, with a mesh opening to wire diameter ratio of 1:1, and the LDPE mesh is compressed to one eighth to one fifteenth of the volume to fill the cavity of the outer frame 12 .

[0031] When the water air purifier is working, first add the external water source into the water tank through the water inlet 6, and stop the external water inlet after the electronic float 4 detects that the water is full; after the water tank is full, start the system program, first the water pump 3 and the centrifugal fan 19 start working at the same time, the water in the water tank enters the water sprinkling cavity 15 in the outer frame through the water pump 3 and the upper water pipe 11, and then disperses and flows out from the small holes of the water sprinkling cavity 15, the water flows downward to penetrate the LDPE filling net 10 and then returns to the water tank through the water tank cover 5 to form a cycle, the centrifugal fan 19 drives the air flow from the outer frame around to enter the LDPE filling cavity, the air flow passes through the tiny water droplets formed in the LDPE filling cavity and fully contacts the water, and the air flow passes through the vent of the water sprinkling sealing cavity and is discharged from the centrifugal fan outlet. To achieve the purpose of purifying the air, the water air purifier can remove pollutants such as PM2.5 and formaldehyde, and does not need to replace the filter, only the water in the water tank needs to be replaced regularly, so as to achieve the purpose of energy saving and environmental protection.

[0032] This embodiment uses water as the filtering medium, and uses the water's ability to absorb PM2.5 and the property that formaldehyde is soluble in water. The water is pumped into the water sprinkling cavity in the outer frame, and the water is dispersed into a number of water drops through the water outlet in the sprinkling cavity, and flows downward into the LDPE mesh filler (a mesh structure of a non-absorbent flexible material) that has been squeezed and compressed to increase density. The water droplets are separated again through the filler and become a number of tiny water droplets. At this time, the water increases the specific surface area. When the airflow passes through the filler, the air can be more fully in contact with the water, thereby enhancing the ability of water to purify the air, and at the same time, the impact on air humidity is also small. This embodiment is a preferred embodiment.
