【Detailed ways】

The utility model is described in detail below in conjunction with accompanying drawing:

A brush lifting mechanism used in the floor brush of a vacuum cleaner, the lifting mechanism is used on the floor brush sweeping disc, and includes a casing 1, a brush 2 is arranged at the bottom of the casing 1, and a brush 2 is arranged at the bottom of the casing 1 The inside is provided with a brush fixture 3, the brush 2 is arranged on the brush fixture 3, a support surface 5 is provided on the brush fixture 3, and the support surface 5 is an inclined surface. Above the support surface 5 is provided a joystick 4 that can make the brush 2 rise and fall, the joystick 4 is rotatably arranged in the housing 1, and a handle is arranged between the brush fixing part 3 and the housing 1 The reset spring 6 is provided with a plane 9 for blocking the spring 6 on the brush holder 3, one end of the spring 6 is supported on the bottom of the housing 1, and the other end is supported on the plane 9 on the brush holder 3 , in the reset state, the spring 6 withstands the brush fixing part 3, so that the brush 2 on the brush fixing part 3 is accommodated in the housing 1.

A handle 41 is provided above the joystick 4, and a protruding rod 411 extends below the handle 41. The protruding rod 411 passes through the cover hole 11 of the housing 1 and is inserted into the sleeve hole 412 above the joystick 4. The bottom of the handle 41 extends downwards with a buckle strip 413, and the buckle strip 413 is buckled on the lower edge 414 of the sleeve hole 412, so that the handle 41 will not run out of the sleeve hole 412. The assembly is firm and convenient, and when the handle 41 Only change handle 41 when damaged, do not cause waste of material; The lower end of described joystick 4 is provided with a pushing surface 7, and described pushing surface 7 is the inclined surface that matches supporting surface 5, and this pushing surface 7 is supported on the support surface 5 on the brush fixing part 3; a shaft 10 is extended from both sides of the joystick 4, and the shaft 10 is sleeved in the housing 1, and the joystick 4 can be transported around the shaft 10 ; The upper end of the supporting surface 5 is provided with a groove 8 for convenient positioning of the pushing surface 7, and the bottom edge of the pushing surface 7 can be placed in the groove 8; It is used to block the plane 9 of the spring 6. One end of the spring 6 is supported on the bottom of the housing 1, and the other end is against the plane 9 on the brush holder 3. In the reset state, the spring 6 will withstand the brush holder 3 , so that the brush 2 on the brush holder 3 is accommodated in the casing 1 .

The utility model works like this: when the handle 41 of the joystick 4 is pulled backwards, the joystick 4 rotates around the shaft 10, and the push surface 7 at the lower end of the joystick 4 will contact the support on the brush holder 3 When the surface 5 slides, under the action of the pulling force, the pushing surface 7 will push the supporting surface 5 downward, and the brush fixing part 3 will move down with the brush 2, exposing the bottom surface of the shell 1, and continue to pull Move the handle 41, the push surface 7 will continue to slide upward on the support surface 5, when the push surface 7 slides to the groove 8 on the support surface 5, the bottom edge of the push surface 7 will be positioned in the groove 8 , loosen the handle 41, under the action of the groove 8, the pushing surface 7 and the supporting surface 5 will not slide against each other, and the function of extending the brush 2 will be realized, and the ground brush can be used; on the contrary, when the brush 2 is required to be stored When the housing 1 is closed, the handle 41 of the joystick 4 is pulled forward, and under the action of the pulling force, the bottom edge of the pushing surface 7 will jump out of the groove 8, and under the action of the elastic force of the spring 6, The spring 6 pushes the brush 2 back until it is retracted into the shell 1, and the brush 2 realizes the function of stretching out and storing in the shell 1; the operation is simple, practical and convenient.
