The utility model provides an alternate rotating direction changing brush, as shown in Figures 1-2, the alternating rotating direction changing brush includes a screw 1, a power transmission assembly 2, a central brush shaft 3, a sleeve 4. Nut sleeve 5 and telescopic rod 6; one end of the screw 1 is connected to the power transmission assembly 2, and the other end is connected to the central brush shaft 3, and the screw 1 is the same as the central brush shaft 3 The other end of the central brush shaft 3 relative to the screw 1 is provided with the brush head 7 ; the sleeve 4 is sleeved on the central brush shaft 3 and can move along the central brush shaft 3 One end of the nut sleeve 5 is sleeved on the screw 1 and the other end is sleeved on the central brush shaft 3 , and the nut sleeve 5 can move along the axial direction of the screw 1 One end of the telescopic rod 6 is hinged with the sleeve 4, and the other end is provided with the brush head 7. Preferably, the brush head 7 is provided with bristles. The alternating rotating direction changing brush is installed on the pot brusher to brush the pot, which can effectively clean the dirt on the surface of the tableware, improve the cleaning efficiency, and improve the convenience, comfort and quality of our lives.

Preferably, there are three telescopic rods 6 , and the three telescopic rods 6 are rotationally symmetrical around the central brush shaft 3 . Further preferably, a compression spring is arranged in the middle of the telescopic rod 6, and the brush head 7 of the telescopic rod 6 is set to be able to move flexibly. Such a structure can ensure that the brush head 7 is completely integrated with the pot surface at a certain pressure. contact for better cleaning.

In the above, specifically, as shown in FIG. 3 , the power transmission assembly 2 includes a rod 21 , a gear 22 and a power transmission head 23 , and both the gear 22 and the power transmission head 23 are sleeved on the rod 21 . and can rotate together with the rod 21 . The ability to rotate together with the rod 21 is achieved by: a key is provided on the side wall of the rod 21; a through hole is provided in the axial direction of the gear 22 and the power transmission head 23; The hole is provided with a key slot matched with the key.

According to the present invention, the alternating rotating direction changing brush portion further includes an elastic connecting piece 8 , one end of which is connected with the telescopic rod 6 and the other end is connected with the central brush shaft 3 . Preferably, the elastic connecting member 8 is a tension spring. The function of the tension spring is to allow the telescopic rod 6 to perform an expanding and contracting motion while performing a rotational motion.

It should be emphasized that, as shown in FIGS. 4-5 , the nut sleeve 5 and the central brush shaft 3 are rotatable. In the technical solution of the present invention, the nut sleeve 5 is prohibited relative to the central brush shaft 3, it is the central brush shaft 3 that performs the rotational movement. Therefore, in order to prevent the rotation of the central brush shaft 3 from being affected when the nut sleeve 5 does not rotate, the nut sleeve 5 is connected to the central brush shaft 3 through the bearing 11 , specifically In other words, the nut sleeve 5 is sleeved on the central brush shaft 3 through a bearing.
