The electrostatic device 100 is placed in a vertical orientation during use, and the electrostatic device 100 of the present invention is described below with reference to the coordinates in fig. 1.

Referring to fig. 1, in an embodiment of the electrostatic apparatus 100 of the present invention, the electrostatic apparatus 100 includes a charging module 10 and a dust collecting module 20, the charging module 10 is provided with an airflow channel 11 penetrating through two opposite sides thereof for air to pass through, and the charging module 10 can charge particles in the air when the air passes through; the dust collection module 20 is disposed adjacent to the charging module 10 for adsorbing charged particles in the air.

Specifically, the charging module 10 has a front side and a rear side along the air flow direction, the dust collecting module 20 is disposed at the rear side of the charging module 10 and is next to the dust collecting module 20, and the charging module 10 may be fixedly connected to the dust collecting module 20 or may be a separate module. When the charging module 10 is fixedly connected to the dust collecting module 20, the two modules may be fixed by bolts, snap-fit connections, welding, or other reasonable and effective connection methods, which are not limited herein and fall within the protection scope of the present invention.

In an alternative embodiment, the dust collecting module 20 is a two-electrode module, two electrodes are separated from each other, and the two electrodes are respectively connected to the positive electrode and the negative electrode of the power supply, thereby forming a high-voltage electrostatic field between the two electrodes. The particles in the air are charged under the action of the charging module 10, the charged particles enter the high-voltage electrostatic field, then the high-voltage electrostatic field generates an electric field force to the particles to accelerate the movement of the particles, and finally the particles are adsorbed on the electrode with the electric property opposite to that of the charges carried by the particles, so that the air is purified.

Of course, in some other embodiments, the dust collecting module 20 can also be a single electrode module, and when the particles to be adsorbed by the single electrode module are charged with positive charges, the single electrode module can be electrically connected to the negative electrode of the power supply or grounded, and when the particles to be adsorbed by the single electrode module are charged with negative charges, the single electrode module can be electrically connected to the positive electrode of the power supply or grounded. The particles in the air are charged under the action of the charging module 10, and the charged particles enter the dust collecting module 20 and collide with the electrode which is opposite to or grounded with the charges of the particles, because of the principle of opposite attraction, the charged particles are adsorbed on the electrode, so that the air is purified. It should be noted that the electrical conductor used in the single electrode module may be a conductive liquid or a conductive solid.

Alternatively, the dust collecting module 20 may have other structures as long as it can adsorb the charged particles, and all of them are within the protection scope of the present invention.

It can be understood that, in the technical solution of the present invention, the electrostatic device 100 includes a charging module 10 and a dust collecting module 20 which are adjacently disposed, the charging module 10 is provided with an airflow channel 11 penetrating through two opposite sides thereof for air to pass through, when the air passes through the airflow channel 11, the charging module 10 can charge particulate matters in the air, and the dust collecting module 20 can adsorb the charged particulate matters in the air. When air is purified, air flows into the airflow channel 11 in the charging module 10, and under the action of the charging module 10, the particles in the air are charged, and then the charged particles in the air flow into the dust collecting module 20, and the dust collecting module 20 adsorbs and takes away the charged particles in the air, so that the air purification effect can be realized. The electrostatic device 100 can effectively remove particles in the air by utilizing the combined action of the charging module 10 and the dust collecting module 20, has small safety risk, and greatly improves the safety of the electrostatic device 100.

Referring to fig. 1, in an embodiment of the electrostatic device 100 of the present invention, the dust collecting module 20 is disposed adjacent to the charging module 10, and a distance between the charging module 10 and the dust collecting module 20 is less than 2 cm.

In the present embodiment, the distance between the charging module 10 and the dust collecting module 20 is controlled within a range less than 2cm, for example, the distance between the charging module 10 and the dust collecting module 20 is 0cm, 0.5cm, or 1.5 cm. The arrangement can enable the charging module 10 and the dust collection module 20 to be close to each other, and reduce the gap between the charging module 10 and the dust collection module 20, so that the gas with particles is adsorbed by the dust collection module 20 as much as possible, and the air purification effect is improved.

Referring again to fig. 1, in an embodiment of the present invention, the charging module 10 has a first side and a second side, which are sequentially disposed along a flow direction of air, and the dust collection module 20 is disposed at the second side of the charging module 10 and is disposed corresponding to the charging module 10.

Specifically, the first side is the front side of the dust collection module 20, the second side is the rear side of the dust collection module 20, the dust collection module 20 is disposed at the rear side of the charging module 10, and the entire surface of the charging module 10 corresponds to the entire surface of the dust collection module 20, and air flows in from the front side of the charging module 10, flows out from the rear side of the charging module 10, flows in from the front side of the dust collection module 20, and flows out from the rear side of the dust collection module 20. With such an arrangement, the particulate matter-carrying gas can be adsorbed by the dust collection module 20 as much as possible, thereby improving the air purification effect.

Optionally, the area of the charging module 10 is the same as the area of the dust collecting module 20, so that the whole surface of the charging module 10 corresponds to the whole surface of the dust collecting module 20, and thus, the gas with the particulate matters is basically adsorbed by the dust collecting module 20, and the air purification effect is further improved.

Alternatively, the area of the charging module 10 is smaller than that of the dust collection module 20, the entire surface of the dust collection module 20 correspondingly covers the entire surface of the dust collection module 20, and part of the surface of the dust collection module 20 is not corresponding to the surface of the charging module 10. This further ensures that substantially all of the particulate laden air is adsorbed by the dust collection module 20, thereby further enhancing the air purification effect.

In addition, the high-voltage electrostatic field in the charging module 10 can generate ozone, the conductive liquid film can dissolve part of the ozone, and the flowing conductive liquid film can be evaporated to generate a high-humidity environment, so that the decomposition of the ozone is accelerated, the ozone emission is reduced, and the environmental protection performance of the electrostatic device 100 is improved.

Optionally, the dust collecting module 20 uses water as a conductive liquid, which is visible in the daily life environment, so that the water is most easily available, and is not required to be processed, so that the electrostatic device 100 is environment-friendly, and the convenience and safety of use can be improved.

The water inlet 211 is disposed at the upper end of the conductive frame 21 and is connected to the filling space, and the water outlet 212 is disposed at the lower end of the conductive frame 21 and is connected to the filling space, i.e. the filling layer 22 is also disposed between the water inlet 211 and the water outlet 212. When the conductive liquid enters from the water inlet 211, the conductive liquid flows through the surface of the filling layer 22, and a conductive liquid film is formed on the surface of the filling layer 22, the conductive liquid film can adsorb particles in the air, and finally the conductive liquid with the particles flows out from the water outlet 212, and the purified air flows out from the air outlet 221 of the filling layer 22. The hydrophilicity of the filling layer 22 makes it possible to form a conductive liquid film more uniformly on the surface of the filling layer 22, and to improve the purification effect of the electrostatic device.

In the present embodiment, the shape of the filling layer 22 may be a net shape, a honeycomb shape, a flat plate shape, a profile shape, or the like.

Preferably, the filling layer 22 is a honeycomb shape formed by folding hydrophilic aluminum alloy, and has a pipe wall extending downwards and bending, and the pipe wall plays a certain role in blocking particles in air. When the air blows to the dust collecting module 20, part of the particles which are not adsorbed on the conductive liquid film can impact the pipe wall on the honeycomb, so that the conductive liquid film further takes away the particles, and the purifying effect of the electrostatic device can be effectively improved.

With such an arrangement, after the conductive liquid adsorbing the particles flows out from the water outlet 212 of the dust collection module 20, the conductive liquid enters the circulation box 23 through the inlet 231 to be filtered, so as to remove the particles carried by the conductive liquid, and then the filtered conductive liquid is discharged from the outlet 232 and flows into the dust collection module 20 again from the water inlet 211, so that the dust collection module 20 and the circulation box 23 form a complete closed loop. The circulation box 23 is used for filtering the conductive liquid, so that the conductive liquid can be recycled, and the use cost of the electrostatic device 100 is reduced.

It should be noted that, a precipitator and a bactericide can be added to the circulation box 23 periodically, the precipitator can promote the precipitation of particles, and the bactericide can sterilize the circulation liquid, so that the circulation liquid can be prevented from affecting the dust collection module 20, and the dust collection module 20 can be protected.
