Electric board brush

[0017] Refer to figure 1 , figure 2 Shown: an electric brush, including a brush body (10), a battery (6), a permanent magnet (12), an electromagnet (7) and a frequency converter (8); the brush body (10) includes a shell ( 5) and the cleaning head (4); the housing (5) has an arc-shaped handle (3); the battery (6), the electromagnet (7) and the frequency converter (8) are arranged in the housing The upper part of the body (5), the permanent magnet (12) is arranged on the upper part of the cleaning head (4), one of the magnetic poles of the permanent magnet (12) and the electromagnet (7) are arranged opposite to each other, the battery (6) and the frequency converter ( 8) Connection, the inverter (8) is connected with the electromagnet (7), the battery (6) generates direct current through the inverter (8) into alternating current and supplies the electromagnet (7) to make the electromagnet (7) generate an alternating magnetic field; The cleaning head (4) is connected to the top of the housing (5) through a spring (9).

[0018] Since the electromagnet (7) generates an alternating magnetic field, and the magnetic pole of the electromagnet (7) is opposite to one of the magnetic poles of the permanent magnet (12), when the electromagnet (7) is connected to the alternating current generated by the frequency converter (8) , The permanent magnet generates an alternating magnetic field, and the electromagnet (7) alternately generates attraction and repulsion to the permanent magnet (12). Because the cleaning head (4) is connected to the top of the housing (5) through a spring (9), the cleaning The head (4) will constantly vibrate up and down.

[0019] Further, the arc-shaped handle (3) is provided with a switch (2) for controlling whether the ultrasonic vibration module works.

[0020] Further, an electrical jack (1) is provided on the arc-shaped handle (3), and the battery (6) in the casing (5) can be charged through the electrical jack (1).

[0021] Further, the cleaning head (4) can be replaced.

[0022] Further, a charging indicator light (11) is provided on the arc-shaped handle (3).

[0023] Further, the battery (6) is a lithium battery.

[0024] The working principle of the present invention is: when the user uses the electric brush, the switch (2) is turned on, the electromagnet (7) generates an alternating magnetic field, and the electromagnet (7) alternately generates attraction and repulsion to the permanent magnet (12). The cleaning head (4) described is connected to the top of the housing (5) through a spring (9), the cleaning head (4) will vibrate up and down continuously, and the user holds the arc-shaped handle (3) and moves the clothes back and forth on the clothes. In addition, the cleaning head (4) is connected to the top of the housing (5) through the spring (9), which ensures that the cleaning head (4) has a higher vibration frequency and is not easy to damage the clothing; The arc-shaped handle (3) is provided with an electric socket (1), through which the battery (6) in the casing (5) can be charged through the electric socket (1), without the need to replace the battery (6), and the operation is very Convenience.

[0025] The beneficial effect of the electric plate brush provided by the present invention is that the electromagnet (7) generates an alternating magnetic field, and the magnetic pole of the electromagnet (7) is opposite to one of the magnetic poles of the permanent magnet (12), when the electromagnet (7) ) After the alternating current generated by the frequency converter (8) is applied, the permanent magnet generates an alternating magnetic field, and the electromagnet (7) alternately generates attractive and repulsive forces on the permanent magnet (12), because the cleaning head (4) passes through the spring (9) Connected to the top of the housing (5), the cleaning head (4) will constantly vibrate up and down, and the user holds the arc-shaped handle (3) when brushing the clothes back and forth on the clothes to make the clothes cleaner. In addition, the cleaning head (4) is connected to the top of the housing (5) through the spring (9), which ensures that the cleaning head (4) has a higher vibration frequency and is not easy to damage the clothes; due to the arc-shaped handle (3) An electric jack (1) is provided, and the battery (6) in the casing (5) can be charged through the electric jack (1) without replacing the battery (6), the operation is very convenient, and the user's effort is saved. The utility model has the advantages of simple structure, convenient use, simple manufacture, low cost and wide application range.

[0026] It should be understood that the foregoing specific embodiments of the present invention are only used to exemplarily illustrate or explain the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
