Detailed Description
Example 1
FIGS. 3 and 4 are schematic diagrams illustrating a conventional state according to an embodiment of the invention; fig. 5 and 6 are schematic diagrams illustrating a braking state according to an embodiment of the invention. As shown in fig. 3 to 6, the present invention provides an accessory tool for connecting a cleaner body for cleaning a floor surface, comprising: a floor brush body 100 having a roller 110, and a floor brush joint 200 connected to the floor brush body 100. The brush adapter 200 is used to connect a dust suction pipe (not shown), and the brush adapter 200 is rotatable with respect to the brush body 100. When the floor brush is used normally, the floor brush main body 100 is close to the ground and parallel to the ground, and a user needs to hold the cleaner main body in the use process, and the floor brush connector 200 is obliquely connected to the dust collection pipe because the cleaner main body and the floor brush main body 100 have a height fall; the roller 110 is used to reduce friction when the brush body 100 moves on the ground. In order to prevent the problem of collision or damage of the machine body caused by too small rolling of the friction force of the roller as described in the background art, the tool further comprises a braking mechanism for limiting the rotation of the roller 110, wherein the braking mechanism is positioned between the roller 110 and the ground brush joint 200, and an inner cavity is formed on one side of the surface of the roller, which is axially oriented to the ground brush joint 200, so as to accommodate at least part of the braking mechanism. The braking mechanism includes a friction part 310, an elastic assembly for applying force to the friction part 310, and an ejector part 210 correspondingly provided on the ground brush joint 200. As shown in fig. 5 and in conjunction with fig. 6, when the brush joint 200 is in the first position for limiting the rotation of the roller, including in a non-use condition or a charged condition, the whole cleaner is kept still against the wall, in order to prevent the roller 110 from rolling to drive the cleaner to fall along the vertical wall, a braking state is required, the elastic component is pushed by the pushing portion 210 due to the overturning and bending action of the brush joint 200 relative to the brush main body 100, the friction portion 310 abuts against the roller 110, and the friction portion abuts against the inner side of the skirt of the roller due to the skirt of the roller, so that the friction force is increased to limit the rotation of the roller. As shown in fig. 3 in combination with fig. 4, when the brush joint 200 is located at the second position of the restriction-releasing roller, the cleaner is in a working state, and the angles between the brush main body 100 and the brush joint 200 are very small, and even are almost parallel or on the same straight line, that is: in a normal state, the push portion 210 is released and the elastic member moves the friction portion 310 away from and out of abutment with the roller 110.
In various embodiments of the present invention, the specific structure and movement of the elastic member are different, and are described one by one. Specifically, in the present embodiment, as shown in fig. 4 and in combination with fig. 6, the elastic assembly includes a spring seat 321 disposed along a radial direction of the roller 110, a spring 322 disposed along the radial direction of the roller, and a transition piece 330. In the present embodiment, the movement principle of the friction part 310 is similar to leverage, the contact position of the friction part 310 with the transition piece 330 is used as a fulcrum of the lever, the contact position of the push part 210 with the friction part 310 is used as one end of the lever to bias, and the friction surface 311 of the friction part 310 is used as the other end of the lever. One end of the friction portion 310 is a friction end, the friction end is disposed in the inner cavity of the roller 110, the other end of the friction portion is rotatably disposed in the spring seat 321 through the transition piece 330, the spring 322 abuts against between the other end of the friction portion 310 and the spring seat 321, and the pushing portion 210 is located below the friction portion 310. The pushing part 210 is protruded on the outer wall of the ground brush joint 200, and comprises a protruding part 211 protruding on the outer surface of the ground brush joint 200, and the protruding part 211 has an outer contour line with a gradual curve.
As shown in fig. 4 in combination with fig. 6, the specific working procedure of this embodiment is as follows:
as shown in fig. 4, in the conventional state, the protrusion 211 of the push part 210 is not in contact with the bottom of the friction part 310, and a certain interval is maintained between the friction part 310 and the inner cavity side wall of the roller 110 under the elastic support of the spring 322, so that the roller 110 can freely rotate without any interaction with the ground brush joint 200. Under the elastic biasing action of the spring 332, the friction portion 310 is pushed radially inwards, so that the friction surface 311 at the other end of the friction portion 310 is kept at a distance from the inner side wall of the roller cavity, and no additional friction force is applied to the roller 110. As shown in fig. 6, in a braking state, including a non-use state or a charging state, the whole dust collector is kept still against a wall, the turnover ground brush joint 200 makes the ground brush joint rotate to an included angle close to 90 ° with the ground brush main body 100, and since the push-up part 210 protruding on the outer wall of the ground brush joint comprises the protruding part 211 protruding on the outer surface of the ground brush joint 200, and the protruding part 211 has an outer contour line with a gradually changing curve, in the process of turnover the ground brush joint 200, the protruding part 211 pushes up the bottom of the friction part 310, so that the friction part 310 turns around a straight line contacting with the transition piece 330 as a central axis, the friction surface 311 is driven to be close to the inner cavity side wall of the roller 110, dry friction between the friction surface 311 and the side wall of the brake friction piece is prevented, and the roller is prevented from continuing to rotate, thereby playing a role of braking. That is, the user operates the joint to rotate relative to the brush head, so that the protruding part of the pushing top can prop up the braking part, the braking part is similar to a lever, one end of the braking part is jacked up by the protruding part and then rotates against the spring, and the other end of the braking part abuts against the roller, so that the purpose of braking is achieved. When the dust collector needs to be used normally, the angle between the ground brush joint and the ground brush is restored to the horizontal state, so that the protruding part does not push against the braking part any more, and the dust collector is reset under the action of the spring, so that the braking is released.
Example two
FIG. 7 is a schematic diagram of a second conventional state according to an embodiment of the present invention; fig. 8 is a schematic diagram of a second braking state according to an embodiment of the invention. As shown in fig. 7 and fig. 8 in combination, in this embodiment, the elastic assembly also includes a spring seat 321, a spring 322 and a transition piece 330 disposed along the radial direction of the roller 110, one end of the friction portion 310 is a friction end, and is disposed in the inner cavity of the roller 110, the other end is fixed in the spring seat 321 through the transition piece 330, the spring 322 abuts against between the other end of the friction portion 310 and the spring seat 321, and the pushing portion 210 is located below the friction portion 310. Under the condition of no use or charging, the whole dust collector is kept still against the wall at this moment and is in a braking state, the ground brush connector 200 is turned over to enable the included angle between the ground brush connector and the ground brush main body 100 to be close to 90 degrees, and the difference with the first embodiment is that in the present embodiment, under the action of the pushing portion 210, the protruding portion 211 directly abuts against the bottom of the friction portion 310, so that the protruding portion moves along the radial direction of the roller 110, and further the friction surface 311 is driven to be close to the side wall of the inner cavity of the roller 110, so as to achieve the purpose of braking. When the cleaner is required to be used normally, the brush joint 200 is rotated to a position almost parallel to or in the same line with the brush main body 100, the protruding part 211 is not propped against the bottom of the friction part 310, and the friction surface 311 is far away from the inner cavity side wall of the roller 110 under the elastic restoring force of the spring 322, so that the roller 110 can rotate freely.
That is, the present embodiment is different from the first embodiment only in the movement mode of the friction portion 310, which is the tilting movement in the first embodiment, and the up-and-down movement in the present embodiment. Regardless of which motion is used, effective braking of the roller 110 is achieved.

As shown in fig. 9 in combination with fig. 10, the specific operation of this embodiment is as follows:
as shown in fig. 9, in the conventional state, the ground brush joint 200 is rotated to a position almost parallel to or in the same line as the ground brush body 100, the push portion 210 and the spring seat 321 are not contacted with each other, and the roller 110 can be rotated normally; referring to fig. 10, when the vacuum cleaner is not in use or is charged, the whole vacuum cleaner is kept still against the wall and is in a braking state, the turning-over brush connector 200 enables the brush connector to rotate until the included angle between the brush connector and the brush main body 100 is close to 90 degrees, the push-up part 210 is in contact with the spring seat 321, the spring seat 321 further pushes the spring 322 to displace along the axial direction of the roller 110, the spring seat 321 drives the friction end to move along the same direction, and the friction surface 311 is in contact with the side wall of the roller cavity to generate a braking effect. When the normal state needs to be restored, the ground brush joint 200 is turned in the opposite direction, the push top 210 is far away, and the ground brush joint is restored under the elastic action of the spring 322.
