In addition, by replacing different brush heads, the functionality of the electric brush can be improved.

[0003] In the prior art, in order to enable the electric brush to extend into spaces of different sizes and shapes for cleaning when in use, the brush head mostly adopts a movable connection method. However, when the electric brush adopts this method for cleaning, if the user applies too much force or the motor vibrates, the brush head is easily offset due to the force, and the user needs to retract the electric brush and adjust it again before cleaning, which is inconvenient. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an electric brush, which can prevent the brush head from being offset due to force when the user is cleaning by setting a limiter, thereby improving the stability of the brush head during operation.

[0011] Furthermore, a connecting seat is provided at the bottom end of the supporting portion, and is connected to the rod body via the connecting seat.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting the limiting part, the brush head will not be deflected due to force when the user is cleaning, thereby improving the stability of the brush head during the working process;

[0014] By pressing the extrusion seat to make the extrusion block start to move, the limiting frame and the limiting block are pushed downward under the guidance of the inclined surface, so that the limiting block is separated from the groove at the bottom of the flip seat. The user can adjust the angle of the drive part and the flip seat. By loosening the extrusion seat, the limiting block can be inserted into the groove at the bottom of the flip seat again under the action of the elastic force of spring one and spring two, which can avoid the brush head from being offset when the user is in use, thereby improving the convenience and accuracy of cleaning.

[0020] See also Figure 1-2 , the utility model provides a technical solution:

[0021] An electric brush comprises a support portion 1, a drive portion 3, a magnetic seat 4 and a brush head 18 plugged into the magnetic seat 4, wherein the drive portion 3 is connected to the top of the support portion 1 via a flip seat 2, wherein the support portion 1 has a control component 6 and a power supply unit, the power supply unit comprises a storage shell, a battery in the storage shell is electrically connected to a charging conductive member, and a sealing effect is improved by a sealing plug arranged on one side of the storage shell, the control component 6 comprises a control button, a display screen and a circuit board, the battery is used to supply power to the circuit board, the drive portion 3 comprises a shell and an actuator arranged inside the shell, the output shaft of the actuator is connected to the magnetic seat 4, and the magnetic seat 4 drives the brush head 18 to rotate by controlling the actuator to work.

[0022] like Figure 1 As shown, a mounting groove 8 corresponding to the flip seat 2 is provided at the top of the support portion 1 , and a limiting member for limiting the rotation of the flip seat 2 is provided on the support portion 1 .

[0023] like Figure 2 As shown, connecting rings 7 are provided on both sides of the flip seat 2, and protrusions 9 are provided on the outer peripheral surface of the connecting ring 7. The inner wall of the mounting groove 8 is provided with a plurality of grooves 10 corresponding to the protrusions 9. By adopting the above structure, with the cooperation of the protrusions 9 and the grooves 10, it can play a role in simple positioning and fixing when the angle of the driving part 3 and the flip seat 2 is adjusted.

[0024] Furthermore, the limiting member includes an extrusion seat 11, which is socketed with the support portion 1. One end of the extrusion seat 11 extends to the interior of the support portion 1 and is provided with an extrusion block 12. A limiting frame 14 is socketed on the extrusion block 12. A limiting block 17 is provided at the bottom of the limiting frame 14. A plurality of grooves corresponding to the limiting block 17 are provided at the bottom of the flip seat 2. When the angle of the driving portion 3 and the flip seat 2 needs to be adjusted, the extrusion seat 11 is pressed to cause the extrusion block 12 to start moving. Under the extrusion of the extrusion block 12, the limiting frame 14 drives the limiting block 17 to move downward, so that the limiting block 17 is separated from the groove at the bottom of the flip seat 2, thereby releasing the restriction on the driving portion 3 and the flip seat 2.

[0025] It should be noted that the plurality of grooves 10 correspond one to one with the grooves at the bottom of the flip seat 2 , that is, when the protrusion 9 is located in any groove 10 , the limiting block 17 is located directly below one of the grooves.

[0026] Furthermore, the cross-section of the extrusion block 12 is a right-angled trapezoidal structure, and the height of the inner wall of the limiting frame 14 is twice the height of the extrusion block 12.

The notch 15 has the same inclination as the inclined surface of the extrusion block 12. By providing the notch 15 and making the notch 15 have the same inclination as the inclined surface of the extrusion block 12, it is convenient for the user to extrude the extrusion seat 11.

[0027] A spring 13 is arranged between the extrusion seat 11 and the flip seat 2, and a spring 2 16 is arranged between the lower surface of the limiting frame 14 and the bottom of the inner wall of the mounting groove 8. When the driving part 3 and the flip seat 2 are rotated to a suitable angle, the extrusion seat 11 is released, and the limiting block 17 is quickly inserted into the groove at the bottom of the flip seat 2 under the elastic force of the spring 1 13 and the spring 2 16, thereby completing the restriction of the driving part 3 and the flip seat 2.
