Summary of the Utility Model

[0005] The purpose of this utility model is to provide an electrostatic precipitator for the existing technical problems, so as to achieve the effect of changing the dust collection direction according to the holding and pushing direction during dust collection and enhancing the dust collection efficiency.

[0012] In this technical solution, the electrostatic precipitator is composed of a housing, an end cover and a dust removal device. Among them, the housing is cylindrical, the cross section of the housing is in an inverted U shape, a storage cavity is arranged inside the housing, an opening is arranged at the bottom of the housing, a rubber pad is arranged on the side wall of the housing, and knurling is arranged on the outer side of the rubber pad. The rubber pad and the knurling enable users to better hold this technical solution, prevent this technical solution from falling off during the dust removal process, and improve the practicability of this technical solution.

[0013] The end cover is placed at the bottom of the housing, the end cover is detachably connected to the housing, a moving plate is coaxially arranged on the end cover with the opening of the housing, a number of balls are arranged between the moving plate and the end cover, spherical grooves matching the balls are arranged on both the moving plate and the end cover, the balls are placed in the spherical grooves, the moving plate and the end cover are rotationally connected by the balls, a dust removal rack is arranged on the moving plate, the dust removal rack is placed in the storage cavity, the cross section of the dust removal rack is in an inverted U shape, and a dust removal through groove is arranged at the corresponding position of the bottom opening of the moving plate and the dust removal rack.

[0014] The dust removal device is placed on the dust removal rack. The dust removal device is provided with a switch, a battery, a rotating motor, a driving dust removal wheel and a driven dust removal wheel. The rotating motor draws electric energy from the battery through an electric wire. The switch is arranged outside the housing for turning on and off the rotating motor. The rotating motor drives the driving dust removal wheel to rotate, and the driving dust removal wheel drives the driven dust removal wheel to rotate, so as to achieve the purpose of dust removal.

[0015] In this technical solution, because a moving plate is rotationally connected to the end cover by balls on the end cover, and a dust removal device is also arranged on the moving plate. When this technical solution needs to remove dust, the switch is turned on to make the driving dust removal wheel and the driven dust removal wheel rotate to remove dust. When the user changes the advancing direction of this technical solution, because there are balls arranged between the end cover and the moving plate, it can turn in time to prevent jamming during the dust removal process, improve the dust removal efficiency and the use comfort, and improve the practicability of this technical solution.

[0016] Furthermore, the rotating motor and the battery are placed on the top of the dust removal frame, the active dust removal wheel and the driven dust removal wheel are placed at the bottom opening of the dust removal frame and are rotatably connected to the dust removal frame, the active dust removal wheel and the output shaft of the rotating motor are both provided with a transmission wheel, the transmission wheel is provided with a transmission belt, the active dust removal wheel and the driven dust removal wheel are abutted, the contact surface of the bottom of the active dust removal wheel and the driven dust removal wheel with the object is lower than the lower end surface of the end cover, a friction rod is centrally arranged in the dust removal groove, the friction rod is abutted against the active dust removal wheel and the driven dust removal wheel, a driving gear is provided at the end of the active dust removal wheel away from the transmission wheel, and a driven gear is provided at the end of the driven dust removal wheel close to the driving gear, and the driving gear and the driven gear are in the same plane and meshed with each other.

[0017] The driving gear and the driven gear are in the same plane and meshed with each other, so that the driving gear and the driven gear can better drive the driven gear to rotate, thereby improving the dust removal efficiency.

[0018] In this technical solution, when it is necessary to remove dust from items, the rotating motor uses the transmission wheel and the transmission belt to drive the active dust removal wheel, and the active dust removal wheel drives the driven dust removal wheel for transmission. When the active dust removal wheel and the driven dust removal wheel rotate, they will generate friction with the friction rod and thus generate static electricity. The static electricity is used to adsorb dust, thereby improving the practicality of this technical solution.

[0019] Furthermore, a scraper is provided on the dust removal frame, and the scraper is arranged parallel to the end cover. The two sides of the scraper are respectively against the active dust removal wheel and the driven dust removal wheel. A fan is detachably connected to the upper plane inside the dust removal frame. A dust collecting box is provided between the fan and the scraper. The dust collecting box is detachably connected to the dust removal frame. An opening is provided at the bottom of the dust collecting box at a position corresponding to the scraper, and a number of filter holes are evenly arrayed at the top of the dust collecting box at a position corresponding to the fan.

[0020] In this technical solution, a scraper is provided on the dust removal frame. The scraper is arranged parallel to the end cover. Both sides of the scraper are in contact with the active dust removal wheel and the driven dust removal wheel respectively. An upper plane inside the dust removal frame is detachably connected with a fan. The fan is connected to a battery through an electric wire. A dust collection box is arranged between the fan and the scraper. The dust collection box is detachably connected to the dust removal frame. An opening is provided at a position corresponding to the scraper at the bottom of the dust collection box. A plurality of filter holes are evenly arranged in an array at positions corresponding to the fan at the top of the dust collection box.

[0021] In this technical solution, when the surfaces of the active dust removal wheel and the driven dust removal wheel are adsorbed with dust after rotating one circle, the active dust removal wheel and the driven dust removal wheel come into contact with the scraper. The scraper scrapes the dust on the surfaces of the active dust removal wheel and the driven dust removal wheel, so that the active dust removal wheel and the driven dust removal wheel always remain clean when contacting the article to be dusted, improving the dust removal efficiency. When the dust is scraped off by the scraper, the fan rotates to blow the air from bottom to top, thereby driving the dust to enter the dust collection box through the opening at the bottom of the dust collection box. Because the filter holes are provided at the top of the dust collection box, most of the dust will not deposit on the fan, thereby improving the service life of this technical solution. When it is necessary to clean the dust collection box, first remove the prime end cover, and then separately remove the dust collection box from the dust removal frame. If the fan blades are also deposited with dust due to long-term use, the fan can also be separately removed for cleaning.

[0022] The beneficial effects of the present utility model are:

[0023] 1. By means of the end cover and the dust removal device, the dust removal direction of this technical solution can be changed according to the traveling direction during use, improving the practicability of this technical solution.
