Referring to fig. 2 again, a steering member 3 is shown, wherein the steering member 3 has two connecting ends for connecting with corresponding structures; wherein the content of the first and second substances,

the first connecting end is provided with a longitudinal shaft 33 for assembly with the handle rod assembly in a relatively rotatable manner, and a stroke limiting structure is arranged between the longitudinal shaft and the handle rod assembly, the stroke limiting structure controls the relative rotation amplitude between the longitudinal shaft and the handle rod assembly, and the rotation amplitude is generally too large, for example, 360-degree complete rotation can cause inconvenience to the operation of the mop.

The two sides of the second connecting end are provided with transverse shafts 30, the transverse shafts on the two sides can be integrated or can be separately arranged on the two sides of the second connecting end respectively, the transverse shafts 30 are provided with inner cavities 31, limiting pieces 32 are installed in the inner cavities 31, through holes 310 are formed in the wall surfaces of the inner cavities 31 to expose the limiting pieces 32, and the limiting pieces 32 have elasticity so that the exposed parts of the limiting pieces can stretch and move relative to the through holes.

The box body is provided with an accommodating cavity 21 matched with the transverse shaft 30 of the second connecting end of the steering member 3, the accommodating cavity 21 is generally arranged on the top cover 20, and the transverse shaft 30 can be arranged in the box body in a front-back rotating mode; the wall of the accommodating cavity 21 is provided with a limiting groove 22 adapted to the exposed part of the limiting member 32, the front side of the limiting groove 22 is provided with a stopping protrusion 220, the rear side of the limiting groove 22 is provided with a guiding part 221, the guiding part 221 is used for guiding and matching the limiting member 32 to run, the surface of the guiding part can be a curved surface, and the front part is high and the rear part is low.

In one embodiment, the body of the steering member 3 is a cylinder with a certain length, the first connecting end is the top of the cylinder, the longitudinal shaft 33 with a smaller radial dimension is arranged on the top of the cylinder, the second connecting end is the bottom of the cylinder, the transverse shaft 30 is arranged on two sides of the bottom of the cylinder, and the longitudinal shaft 33 and the transverse shaft 30 are assembled with corresponding structures, so that the steering member 3 has flexibility of two rotation directions between the two assembled structures. The limiting member 32 of the transverse shaft 30 is elastic, and the exposed portion of the limiting member 32 can be extended and retracted at the through hole 310 after being stressed, and the exposed portion of the limiting member 32 can be matched with the limiting groove 22 to control the rotation between the structures.

The assembly of the handle assembly 1 and the steering member 3 is detachable, and for example, the assembly is preferably realized by an elastic buckle, such as a common buckle. The elastic buckle comprises a V-shaped elastic sheet and a button, the V-shaped elastic sheet is arranged in the cylindrical steering piece 3, one elastic sheet is attached to the inner wall of one side of the steering piece 3, the exposed button is arranged on the elastic sheet, the other elastic sheet obliquely abuts against the inner wall of the other side of the steering piece 3, and the elastic force between the two elastic sheets acts on the button. The bottom end of the handle rod component 1 is provided with a button groove matched with the button, and the button groove has a certain length, so that the requirement of relative movement of the button when the handle rod component 1 rotates is met, and interference is avoided.

The handle assembly 1 is generally installed at a rear position of the head assembly 2 (a small amount of the handle assembly may be installed at a middle position), the user holds the handle assembly 1 to stand behind the head assembly 2 when operating the electric mop, the handle assembly 1 is inclined backward (a person stands), and then the user applies force forward and backward to drag the head assembly 2 back and forth on the bottom surface.

The handle rod assembly 1 is assembled with the first connecting end of the steering piece 3, the electric mop obtains a first rotational degree of freedom, the head assembly 2 is assembled with the second connecting end of the steering piece 3, the electric mop obtains a second rotational degree of freedom, and the two rotational degrees of freedom can enable the electric mop to be more flexibly cleaned. The second rotational degree of freedom plays a certain role in limiting through the cooperation of the limiting member 32 and the limiting groove 22, when the handle assembly 1 rotates forward compared with the handle assembly 2, the handle assembly is interfered by the stopping protrusion 220, the stopping protrusion 220 is higher, and even if the limiting member retracts elastically, the limiting member cannot bypass the limiting protrusion 220, so that the limiting member 32 cannot be separated from the limiting groove 22, and the handle assembly 1 is prevented from rotating forward; when the handle assembly 1 is rotated backward compared with the handle assembly, the exposed part of the position-limiting element 32 is slightly retracted under the elastic action and then moves forward along the guiding part 221 (the height of the guiding part 221 is small, and the position-limiting element 32 can bypass after being retracted).

The random rotation of handle pole subassembly 1 can be avoided in the cooperation of spacing groove 22 and locating part 32, for example, handle pole subassembly 1 generally is fore-and-aft state of placing when putting, if handle pole subassembly 1 is too nimble with being connected of head subassembly 2, handle pole subassembly 1 will fall down easily, occupy too much space, or hit other objects, people, in addition handle pole subassembly 1 need not like preceding rotation in the use, so restrict through backstop arch 220, and guide portion 221 can arouse the level and smooth completion of locating part 32 to break away from or reset from spacing groove 22, guarantee the stability of operation.

The non-closed ring body makes the position limiting member 32 have elasticity, and simple structure, can integrated into one piece. After the limiting protrusion 320 is exposed through the through hole 310, when the handle assembly 1 rotates, the ring body of the limiting member 32 is slightly closed and sunk under the action of the guiding part 221, so that the limiting protrusion 320 is recovered to be separated from the limiting groove 22, the limiting protrusion 320 enters the limiting groove 22 during resetting, and the non-closed ring body is recovered. The non-closed ring body is matched with the wall surface of the inner cavity 31, and the wall surface of the inner cavity 31 plays a certain guiding role in elastic opening and closing of the ring body, so that the elastic performance of the non-closed ring body is stably exerted.

The relative rotation between the handle assembly 1 and the first connection end can now be satisfactory within a certain range, and a 360 degree rotation will adversely affect the use of the mop, so that a stroke limiting structure is provided between the longitudinal axis 33 and the handle assembly 1.
