The technical solution of the present invention is further explained by the following embodiments with reference to the drawings.

Referring to fig. 1 to 6, an embodiment of the present invention provides a vacuum cleaner, including a machine body and a floor brush assembly, the floor brush assembly includes a casing, a floor brush body 21 and a motor, the floor brush body 21 is connected with the casing through a floor brush rotating shaft 22, and the motor can drive the floor brush rotating shaft 22 to rotate so as to drive the floor brush body 21 to rotate. The floor brush body 21 rotates to lift dust and sundries on the ground, and the dust and the sundries are sucked into the body of the dust collector through the dust suction port on the machine shell so as to realize the cleaning and dust removal of the ground.

The embodiment of the utility model provides a dust catcher is vertical dust catcher, and the fuselage includes handle and push rod, and the handle sets up in the one end of push rod, and the scrubbing brush subassembly sets up in the other end of push rod. When the floor brush is used, the floor brush component is pushed by the machine body to move, and when the floor brush is not used, the machine body is supported by the floor brush component to be in an upright state.

The floor brush assembly further comprises a floor brush connector and a locking assembly 40, the floor brush connector comprises a connector body 31 and a connector rotating shaft 32 which are fixedly connected, the connector body 31 is connected with the machine body, a mounting hole 101 is formed in the machine shell, and the connector rotating shaft 32 is rotatably connected with the mounting hole 101; the locking assembly 40 includes a latch 41, the latch 41 is elastically connected to the housing and disposed obliquely below the connector shaft 32, the latch 41 abuts against the connector shaft 32 to make the connector shaft 32 abut against the inner wall of the mounting hole 101, and the axis of the connector shaft 32 and the axis of the mounting hole 101 are eccentrically disposed.

When the connector is used, the connector rotating shaft 32 rotates in the mounting hole 101, the connector rotating shaft 32 can extrude the lock catch 41 in the rotating process, and the lock catch 41 is elastically connected with the casing, so that the abutting effect of the lock catch 41 on the connector rotating shaft 32 is not influenced, the connector rotating shaft 32 cannot shake in the mounting hole 101, and the rotating process is stable; when the floor brush is not used, the lock catch 41 tightly abuts against the oblique lower side of the connector rotating shaft 32, so that the connector rotating shaft 32 has an upward supporting force in an oblique direction, and even if the floor brush assembly is lifted, the connector rotating shaft 32 cannot easily rotate, and the locking effect is good.

The locking assembly 40 can not only abut against the connector rotating shaft 32, but also be matched and locked with the connector rotating shaft 32.

Specifically, a limiting protrusion 321 is disposed on the outer peripheral surface of the connector rotating shaft 32, and the limiting protrusion 321 can abut against the inner side of the lock catch 41 to enable the body to be in an upright state. With the rotation of the connector spindle 32, the position of the limiting protrusion 321 relative to the latch 41 changes, and when the limiting protrusion 321 is located outside the latch 41, the connector spindle 32 can rotate freely, and at this time, the latch 41 abuts against the connector spindle 32, but does not limit the rotation of the connector spindle 32.

When the limiting protrusion 321 moves to a direction close to the latch 41 and presses the latch 41, the limiting protrusion 321 reaches the inner side of the latch 41 and abuts against the latch 41, as shown in fig. 2, and the main body is in an upright state. If the vacuum cleaner is used, the connector rotating shaft 32 is rotated clockwise, and then a certain external force is applied to enable the limiting protrusion 321 to cross the latch 41 and reach the outer side of the latch 41, and at this time, the connector rotating shaft 32 can rotate freely.

The inner side of the latch 41 is concavely provided with a limiting groove 411, and the limiting protrusion 321 can tightly abut against the limiting groove 411. Spacing groove 411 plays limiting displacement to spacing arch 321 for spacing arch 321 has great area of contact with spacing groove 411, and locking is effectual.

Further, a first guide surface 412 is convexly disposed on an outer side of the latch 41, and the limiting protrusion 321 can slide into the limiting groove 411 along the first guide surface 412. The first guide surface 412 guides the limiting protrusion 321, so that the limiting protrusion 321 can smoothly slide into the limiting groove 411. Wherein the first guide surface 412 may be a curved surface.

The limiting protrusion 321 is provided with a second guide surface 3211, and the second guide surface 3211 can slide along the first guide surface 412. The second guide surface 3211 is engaged with the first guide surface 412, so that the limiting protrusion 321 slides smoothly. The second guide surface 3211 may be a curved surface.

When the limiting protrusion 321 abuts against the latch 41, the body is in an upright state, and in order to limit the counterclockwise rotation of the connecting head rotating shaft 32, the limiting operation needs to be performed outside the latch 41. Specifically, a notch 322 is disposed on the outer peripheral surface of the connector rotating shaft 32, the limiting protrusion 321 is located on one side of the notch 322, and the lock catch 41 can be inserted into the notch 322 and tightly abut against the limiting protrusion 321. When the inner side of the latch 41 abuts against the limiting protrusion 321, if the connecting head rotating shaft 32 tends to rotate counterclockwise, the outer side of the latch 41 will abut against the inner wall of the notch 322 for limiting, so that the connecting head rotating shaft 32 cannot rotate.

The locking assembly 40 further includes a supporting plate 42 and an elastic member 43, the supporting plate 42 is connected to the housing, the latch 41 is slidably connected to the supporting plate 42, and the elastic member 43 is located between the housing and the latch 41. When the limiting protrusion 321 presses the latch 41, the latch 41 presses the elastic member 43, and after the limiting protrusion 321 passes over the latch 41, the latch 41 moves upward to abut against the limiting protrusion 321 under the action of the elastic member 43. The elastic force of the elastic member 43 enables the lock catch 41 to abut against the connecting joint rotating shaft 32, so that the compression amount of the elastic member 43 can be increased to increase the abutting force.

In this embodiment, the supporting plate 42 is detachably connected to the housing through screws, so that the mounting and replacement are facilitated.

The casing includes upper cover 11 and lower cover 12 of looks lock, and first mounting groove has been seted up to upper cover 11, and the second mounting groove has been seted up to lower cover 12, and first mounting groove forms mounting hole 101 with the lock of second mounting groove. The upper cover 11 and the lower cover 12 can be connected by screws, so that the installation and the disassembly are convenient, and the connector rotating shaft 32 is convenient to install.

The embodiment of the utility model provides a scrubbing brush subassembly, when using, spacing arch 321 breaks away from with hasp 41, and connector pivot 32 is at the mounting hole 101 internal rotation, and connector pivot 32 can extrude hasp 41 rotating the in-process, because hasp 41 and casing elastic connection, consequently do not influence hasp 41 to the tight effect of supporting of connector pivot 32 for connector pivot 32 can not rock in mounting hole 101, and the rotation process is steady.

When not using, make spacing arch 321 extrusion hasp 41 through rotating connector pivot 32, spacing arch 321 and the inboard butt of hasp 41, hasp 41 can tightly support spacing arch 321 this moment, supports tightly connector pivot 32 promptly, provides oblique ascending holding power to connector pivot 32, even mention the scrubbing brush subassembly, connector pivot 32 also can not rotate easily for locking is effectual.

The above embodiments have only been explained the basic principle and characteristics of the present invention, the present invention is not limited by the above embodiments, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and modifications all fall into the scope of the present invention.
