[0025] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0026] As Figures 1-7As shown in the figure, this embodiment provides an electric cleaning brush 1, which includes a brush head assembly 10 and a body assembly 20. The brush head assembly 10 and the body assembly 20 can be assembled into an integral whole to form the electric cleaning brush 1.

[0027] The body assembly 20 includes a body housing 23, a motor 21, a power supply 22, and a bracket 24 for fixing the motor 21 and the power supply 22. The power supply 22 can be a storage battery or the like. The motor 21 is used to provide power for the electric cleaning brush 1.

[0028] The brush head assembly 10 includes a brush head housing 12, an eccentric transmission member 19, and a brush head 15. The eccentric transmission member 19 is disposed inside the brush head housing 12. The motor 21 is provided with a rotary output shaft 211. One end of the eccentric transmission member 19 is connected to the rotary output shaft 211 of the motor 21, and the other end of the eccentric transmission member 19 is connected to the brush head 15. The eccentric transmission member 19 is used to convert the rotary motion of the rotary output shaft 211 of the motor 21 into a reciprocating swing of the brush head 15. By converting the rotary motion of the rotary output shaft 211 of the motor 21 into a reciprocating swing of the brush head 15 through the eccentric transmission member 19, the electric cleaning brush 1 is easier to operate, has a good cleaning effect, and is not prone to splashing.

[0029] Specifically, the eccentric transmission member 19 includes a rotary transmission shaft 11, a first transmission member 17, and a second transmission member 16. A transmission interface 111 is provided at the first end of the rotary transmission shaft 11, and the transmission interface 111 is in transmission connection with the rotary output shaft 211 in a matching manner. An eccentric mechanism 112 is provided at the second end of the rotary transmission shaft 11. The eccentric mechanism 112 includes an eccentric convex column 1121, and the eccentric convex column 1121 is eccentrically arranged relative to the rotary transmission shaft 11. The first transmission member 17 is pivotally disposed inside the brush head housing 12 through a first pivot shaft 13. A transmission groove 171 is provided at the first end of the first transmission member 17, and the eccentric convex column 1121 is in butt joint and cooperation with the transmission groove 171 of the first transmission member 17. The rotary transmission shaft 11 and the first transmission member 17 cooperate to convert the rotary motion of the rotary output shaft 211 of the motor 21 into a reciprocating swing of the first transmission member 17. The first transmission member 17 is in transmission connection with the brush head 15, thereby driving the brush head 15 to reciprocate.

[0030] Among them, the transmission groove 171 extends along the axis J direction of the first pivot shaft 13, and better transmission efficiency can be obtained.

[0031] A second transmission member 16 is provided between the first transmission member 17 and the brush head 15. The first transmission member 17 is drivingly connected to the brush head 15 through the second transmission member 16. A first transmission tooth 172 is provided at the second end of the first transmission member 17. The second transmission member 16 is pivotally provided in the brush head housing 12 through a second pivot shaft 14. A second transmission tooth 161 is provided on one side of the second transmission member 16. The first transmission tooth 172 meshes with the second transmission tooth 161 for driving. The second transmission member 16 is drivingly connected to the brush head 15, thereby driving the brush head 15 to swing reciprocally.

[0032] A first mating structure (not shown) is provided on the bottom surface of the second transmission member 16, and a second mating structure 151 is provided on the top surface of the brush head 15. The first mating structure and the second mating structure are a set of convex portions and grooves that can cooperate with each other for limiting, thereby realizing the driving connection between the second transmission member 16 and the brush head 15. In this embodiment, a groove (not shown) is provided on the bottom surface of the second transmission member 16, and a convex portion 151 is provided on the top surface of the brush head 15. The convex portion 151 cooperates with the groove on the bottom surface of the second transmission member 16, so that the rotational swing of the brush head 15 relative to the second transmission member 16 is restricted, and the second transmission member 16 is drivingly connected to the brush head 15.

[0033] When the electric cleaning brush 1 is powered on, the power supply 22 provides energy to the motor 21, and the rotating output shaft 211 starts to rotate. The rotation of the rotating output shaft 211 drives the rotating transmission shaft 11 to rotate, and the rotation of the rotating transmission shaft 11 drives the eccentric convex column 1121 to rotate. Since the eccentric convex column 1121 is eccentrically arranged relative to the rotating transmission shaft 11, the eccentric rotation of the eccentric convex column 1121 is converted into the reciprocating swing of the first transmission member 17 along the F direction through the transmission groove 171. The reciprocating swing of the first transmission member 17 drives the second transmission member 16 to swing reciprocally along the N direction, and the reciprocating swing of the second transmission member 16 drives the brush head 15 to swing reciprocally. Since the rotating output shaft 211 of the motor 21 rotates at a high speed, the brush head 15 is driven to perform a high-speed reciprocating swing through transmission, realizing the cleaning function of the electric cleaning brush 1.

[0034] Refer to Figure 3 , the axis J of the first pivot shaft 13 is perpendicular to the axis G of the rotating transmission shaft 11, so that the rotational motion of the rotating transmission shaft 11 can be converted into the reciprocating swing of the first transmission member 17 with the highest efficiency, and the conversion efficiency is higher.

[0035] The axis of the brush head 15 coincides with the axis K of the second pivot shaft 14. The axis K of the second pivot shaft 14 intersects with the axis G of the rotating transmission shaft 11, and the inner angle A is greater than 95°. This angle setting conforms to the angle at which a person holds the electric cleaning brush 1 for cleaning, and it is more labor-saving and convenient during cleaning.

[0036] The rotating transmission shaft 11 is further provided with a guiding shaft section 113 between the transmission interface 111 and the eccentric mechanism 112. The guiding shaft section 113 is formed as a shaft section with a reduced diameter, so that two shaft shoulders 114 and 115 are formed at both ends of the guiding shaft section 113. A guiding shaft sleeve 18 is sleeved outside the guiding shaft section 113. The guiding shaft section 113 can cooperate with the guiding shaft sleeve 18, and the two shaft shoulders 114 and 115 can cooperate with both ends of the guiding shaft sleeve 18, thereby guiding and limiting the movement of the rotating transmission shaft 11 and making the transmission more stable.

[0037] The brush head housing 12 includes a first housing 121, a second housing 122 and a collar 123. The first housing 121 is installed and connected to the second housing 122, and an inner cavity is formed inside the first housing 121 and the second housing 122 for installing the eccentric drive member 19, the first pivot shaft 13, the second pivot shaft 14 and the guiding shaft sleeve 18. The collar 123 is sleeved on the tails of the first housing 121 and the second housing 122, thereby enhancing the structural strength of the tail of the brush head housing 12. The tail of the brush head housing 12 is used for assembling and connecting with the body housing 23, thereby being able to enhance the connection strength of the assembly connection with the body housing 23 of the body assembly 20.

[0038] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all such changes are within the protection scope of the present invention.
