DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 7 As shown, the utility model provides an electrostatic air purifier, comprising a body 1, with an air inlet end 2 and an air outlet end 3 respectively disposed on both sides of the body 1;

[0024] An air filter plate 14 is installed on the inner wall of the air inlet end 2, an activated carbon filter plate 15 is fixedly installed on the inner wall of the air outlet end 3, and a group of axial flow fans 16 are installed inside the air inlet end 2 and the air outlet end 3;

[0025] When working, the axial flow fan 16 at the air inlet end 2 is used to supply air to the interior of the purifier, and the axial flow fan 16 at the air exhaust end 3 is used to lead the purified gas in the purifier out;

[0026] A power supply module is installed on the device body 1;

[0027] The power supply module includes a central control panel 17 fixed to the surface of the device body 1 and an electric control box built into the device body 1 and electrically connected to the central control panel 17. The two sides of the electric control box are respectively connected with a positive cable and a negative cable. The two sides of the electric control box are respectively installed with a positive ring rail 18 and a negative ring rail 19. The positive ring rail 18 is powered by the positive cable, and the negative ring rail 19 is powered by the negative cable. The positive ring rail 18 and the negative ring rail 19 are both provided with rail grooves.

[0028] The body 1 is internally rotatably connected to an electrostatic cylinder 5 driven by a rotating motor 4, and a dust accumulation valve 11 is connected to the bottom surface of the body 1 and the position directly below the electrostatic cylinder 5;

[0029] A conductive notch is provided on the positive electrode ring rail 18 and the negative electrode ring rail 19 at a position corresponding to the position above the dust accumulation valve 11;

[0030] When the static electricity generating plate 8 moves to the position of the conductive gap, the static electricity generating plate 8 is powered off. After the static electricity generating plate 8 is powered off at the conductive gap, the static electricity generating plate 8 is centrifugally rotated at high speed under the action of the second tooth-missing ring 13. After the static electricity generating plate 8 is centrifugally rotated, the dust adsorbed on the static electricity generating plate 8 is centrifugally thrown out by the centrifugal principle, and the centrifugally thrown out dust is collected by the dust accumulation valve 11.

[0031] A group of regularly distributed and mutually isolated purification chambers 6 are provided inside the electrostatic tube 5. The top of the purification chamber 6 is open and the bottom is a concave arc surface structure.

[0032] The inner wall of each purification chamber 6 is rotatably connected with a rotating shaft 7, and a group of electrostatic generating plates 8 arranged in a circumferential array are installed at the rotating shaft 7 and at the position corresponding to the inner side of the purification chamber 6. The ends of the electrostatic generating plates 8 are rotatably fitted with the purification chamber 6. The rotating shaft 7 is respectively installed with a conductive component and a differential gear a9 and a differential gear b10 for supplying power to the electrostatic generating plates 8, and the conductive component is electrically connected to the power supply module;

[0033] The conductive components respectively include a positive electrode wheel 20 and a negative electrode wheel 21 which are rotatably connected to the rotating shaft 7, the positive electrode wheel 20 is rotatably fitted with the positive electrode ring track 18, and the negative electrode wheel 21 is rotatably fitted with the negative electrode ring track 19, and the static electricity generating plate 8 is powered by the negative electrode wheel 21 and the positive electrode wheel 20;

[0034] When the static electricity generating plate 8 moves to the non-conductive gap position on the positive electrode ring track 18 and the negative electrode ring track 19, the static electricity generating plate 8 generates static electricity and electrostatically adsorbs dust in the air through the principle of electrostatic adsorption;

[0035] A first toothless ring 12 that cooperates with the differential gear a9 and a second toothless ring 13 that cooperates with the differential gear b10 are respectively installed on the side of the body 1. The first toothless ring 12 and the second toothless ring 13 are staggered.

[0036] The first toothless ring 12 is fixedly provided with a transmission gap at a position corresponding to the conductive gap, and the position of the second toothless ring 13 corresponds to the position of the transmission gap.

[0037] The radius of differential gear a9 is 1.5 times the radius of differential gear b10;

[0038] By setting the radius difference between the differential gear a9 and the differential gear b10 and the specifications of the first toothless ring 12 and the second toothless ring 13, the rotating shaft 7 has different rotation speeds when it moves to the positions of the first toothless ring 12 and the second toothless ring 13;

[0039] Specifically, when the rotating shaft 7 passes the position of the first toothless ring 12, the rotating shaft 7 rotates at a low speed, and then drives the multiple static electricity generating plates 8 to absorb dust in the air in the purification chamber 6 in turn;

[0040] When the rotating shaft 7 passes the position of the second tooth-missing ring 13, the rotating shaft 7 rotates at a high speed, and then the dust adsorbed on the static electricity generating plate 8 is centrifugally thrown out through the centrifugal principle.

[0041] The working principle and use process of this utility model:

[0042] During operation, the axial flow fan 16 at the air inlet end 2 is used to supply air to the interior of the purifier, and the axial flow fan 16 at the air exhaust end 3 is used to lead out the purified gas in the purifier. When the purifier is working, the purification cylinder rotates at a set speed. When the rotary shaft 7 passes the position of the first toothless ring 12, the rotary shaft 7 rotates at a low speed, and then drives multiple electrostatic generating plates 8 to take turns to adsorb dust from the air in the purification chamber 6. When the rotary shaft 7 passes the position of the second toothless ring 13, the rotary shaft 7 rotates at a high speed, and then the dust adsorbed on the electrostatic generating plate 8 is centrifugally thrown out by the centrifugal principle. When the electrostatic generating plate 8 moves to the position of the conductive gap, the electrostatic generating plate 8 is powered off. After the electrostatic generating plate 8 is powered off at the conductive gap, the electrostatic generating plate 8 loses its adsorption effect on the dust. Under the action of the second toothless ring 13, the electrostatic generating plate 8 undergoes high-speed centrifugal rotation. After the electrostatic generating plate 8 is centrifugally rotated, the dust adsorbed on the electrostatic generating plate 8 is centrifugally thrown out by the centrifugal principle. The centrifugally thrown dust is collected through the dust accumulation valve 11.

[0043] During operation, the static electricity generating plate 8 is periodically powered on and off and performs periodic electrostatic dust suction and periodic centrifugal dust removal operations. By achieving the above technical effects, the high purification performance of the electrostatic air purifier is maintained.
