As shown in fig. 1 to 4, a floor cleaning apparatus corresponding to a preferred embodiment of the present invention includes a floor brush 4, a main body 5 rotatably coupled to the floor brush 4, and a case 2 provided on the main body 5.

The floor brush 4 is used to wait for the cleaning surface to move on the floor and to be cleaned, and as shown in fig. 1 and 2, is provided with a roll brush 40 which can be rotated by a motor and a water spraying member 41 for spraying a cleaning liquid to the surface to be cleaned, and the water spraying member 41 is provided with water spraying ports for spraying the cleaning liquid. When spraying the cleaning solution, the water spraying member 41 can directly spray the cleaning solution onto the surface to be cleaned, or can spray the cleaning solution onto the rolling brush 40, and then the cleaning solution is transferred onto the surface to be cleaned by the rolling brush 40. The cleaning liquid may be water or another liquid having a cleaning effect.

The floor brush 4 is further provided with a first connecting piece 1, the main body 5 is rotatably connected to the first connecting piece 1, and the manner of the rotatable connection is not limited, in this embodiment, as shown in fig. 4, a rotating shaft hole 10 is provided on the first connecting piece 1, a rotating shaft 53 adapted to the rotating shaft hole 10 is provided on the main body 5, and the rotatable connection is realized in a shaft and hole matching manner.

The box 2 is used for holding the cleaning solution, and in order to make the cleaning solution in the box 2 can supply to the piece 41 that sprays water, the water pipe 3 with box 2 intercommunication is held in the main part 5, and this water pipe 3 one end is connected on the box 2, and the other end downwardly extending is continuous with the piece 41 that sprays water in the scrubbing brush 4. A water pump is further provided in the main body 5 to pump the water in the tank 2 to the water spray 41.

Further, the first connecting member 1 is disposed at the rear side of the water spraying member 41 of the floor brush 4, and when the main body 5 is pivoted to the first connecting member 1, the end portion thereof connected to the first connecting member 1 is also disposed at the rear side of the water spraying member 41. It should be noted that when the user uses the floor cleaning device, the user usually stands behind the floor brush 4 so as to drive the floor brush 4 to move forward, therefore, in the moving direction of the floor brush 4, if the a object is closer to the user than the B object, the a object is located behind the B object, and conversely, if the a object is farther away from the user than the B object, the a object is located in front of the B object.

In order to allow the water pipe 3 to enter the floor brush 4 from the main body 5, as shown in fig. 3, a second water pipe hole 200 is provided at an end portion of the main body 5 rotatably connected to the first connector 1, a first water pipe hole 100 is provided at a position of the first connector 1 corresponding to the second water pipe hole 200, and the water pipe 3 in the main body 5 enters the floor brush 4 after passing through the second water pipe hole 200 and the first water pipe hole 100.

It will be appreciated that since the water jet 41 is positioned in front of the second water pipe hole 200, the water pipe 3 is inserted from the second water pipe hole 200

When inside the floor brush 4, there will be a tendency to tilt towards the water jet 41, which will result in that the water pipe 3 will tend to contact the wall of the second water pipe hole 200. In general, referring to fig. 4, the second water pipe hole 200 includes a first hole wall 201 located relatively forward and a second hole wall 202 located relatively rearward, and in order to facilitate the rotation of the main body 5, the distance between the first hole wall 201 and the second hole wall 202 is set to be larger than the diameter of the water pipe 3, and the tendency of the water pipe 3 to tilt forward will cause it to contact the hole wall (i.e., the first hole wall 201) on the side closer to the water jet 41 on the second water pipe hole 200, so that during the change of the angle of the main body 5 relative to the floor brush 4, the water pipe 3 will rub against the first hole wall 201, resulting in rapid wear of the water pipe 3. In order to prevent or reduce friction between the water pipe 3 and the second water pipe hole 200, an extrusion block 70 is provided in the main body 5, and the extrusion block 70 is configured to form a gap between the water pipe 3 and the second water pipe hole 200 on a side of the water pipe 3 facing the water spout 42, that is, a gap between the water pipe 3 and the first hole wall 201, so that the water pipe 3 does not rub against the hole wall of the second water pipe hole 200, thereby eliminating abrasion caused by friction between the water pipe 3 and the hole wall.

Specifically, as shown in fig. 4, the main body 5 includes a first housing 50 and a second housing 51 connected to the first housing 50, wherein the first housing 50 is located at a front end of the second housing 51, and a housing space 52 for housing the water pipe 3 is formed between the first housing 50 and the second housing 51. The pressing block 70 is located in the receiving space 52 and connected to the first housing 50, and its pressing surface 700 contacting with the water pipe 3 protrudes rearward from the first side wall 201 and is located between the first side wall 201 and the second side wall 202, so as to counteract the tendency of the water pipe 3 to tilt forward, so that the water pipe 3 is located further rearward in the second water pipe hole 200 and forms a gap with the first hole wall 201.

As a preferred embodiment, the pressing surface 700 is a smooth surface. The smooth surface may be, for example, a glass surface, a surface formed by metal polishing, or a surface of a plastic film, and since the smooth surface has a small friction coefficient, the wear of the water pipe 3 and the pressing block 70 during relative movement can be greatly reduced. In this embodiment, the PET film 71 is provided on the extrusion block 70, and the extrusion surface 700 is a surface of the PET film 71. Further, the pressing block 70 is preferably made of an elastic material, so that when being pressed by the water pipe 3, a certain elastic deformation can occur, and soft contact is achieved between the pressing block and the water pipe 3, thereby further reducing the abrasion on the water pipe 3. The elastic material may be, for example, EVA foam or rubber.

As a preferred embodiment, the extrusion block 70 is connected to the first housing 50 by gluing, so that the installation is more convenient and faster.

As shown in fig. 4, a limiting boss 20 is provided in the main body 5 to face the extrusion block 70, and the limiting boss 20 is provided on the second housing 51 and abuts against the extrusion block 70 on both sides of the water pipe 3, so as to better limit the front and rear positions of the water pipe 3 and prevent the water pipe 3 from shaking back and forth. As a preferred embodiment, the abutting surface 200 of the limiting boss 20 contacting with the water pipe 3 protrudes from the second side wall 202, i.e. is located in front of the second side wall 202, and in case of the water pipe 3 having a tendency to tilt forward, it can be ensured that the water pipe 3 does not contact with the second side wall 202, and the frictional wear between the water pipe 3 and the second side wall 202 is prevented.

In a preferred embodiment, the end of the body 5 close to the floor brush 4 is provided with a convex second curved wall 54, while the first connecting member 1 is provided with a concave first curved wall 11, the first curved wall 11 being opposite to the second curved wall 54. The first water pipe hole 100 is formed on the first arc-shaped wall 11, and the second water pipe hole 200 is formed on the second arc-shaped wall 54. The first arc-shaped wall 11 and the second arc-shaped wall 54 are arc-shaped with the axis of the rotating shaft 53 as the center, and the distance between the first arc-shaped wall 11 and the second arc-shaped wall 54 is kept constant during the rotation of the main body 5 relative to the first connecting member 1, so that the pulling and the abrasion of the water pipe 3 can be reduced.

The first sidewall 201 and the second sidewall 202 of the second water pipe hole 200 may be arc-shaped or plane, in this embodiment, the second water pipe hole 200 is a long hole, and the first sidewall 201 and the second sidewall 202 are plane-shaped and arranged in parallel. Meanwhile, the second water pipe hole 200 extends along the circumferential direction of the second arc-shaped wall 54, which can provide more sufficient movement space for the water pipe 3, and reduce the tearing of the water pipe 3 during the rotation of the main body 5, thereby further reducing the abrasion and preventing the looseness of the joint of the water pipe 3 caused by the tearing.

Further, the first water tube hole 100 has an elongated hole shape extending along the circumferential direction of the first arc-shaped wall 11 to reduce the pulling of the water tube 3. The first water pipe aperture 100 includes a third aperture wall 101 and a fourth aperture wall 102. in a preferred embodiment, the distance between the third aperture wall 101 and the fourth aperture wall 102 is greater than the distance between the first aperture wall 201 and the second aperture wall 202, i.e., the third aperture wall 101 is located forward relative to the first aperture wall 201 and the fourth aperture wall 102 is located rearward relative to the second aperture wall 202, so that there is also a gap between the water pipe 3 and the third aperture wall 101 and the fourth aperture wall 102, and there is no wear from contact with the aperture walls of the first water pipe aperture 100.
