Description

Technical Field

[0001] This utility model belongs to the field of floor scrubbers, specifically a double-roller floor scrubber that can lie flat. Background Technology

[0002] Floor scrubbers are widely used in homes and offices, popular for their combined vacuuming and mopping functions. Currently, various models of floor scrubbers have emerged, including one with dual roller brushes. The front roller brush cleans, while the rear roller brush wipes away any remaining water, allowing the floor to dry quickly and preventing secondary contamination from water residue. However, the dual-brush design results in a larger brush area, especially the rear brush section, which has an angle that hinders the main unit's backward movement. This prevents the main unit from lying flat, making it difficult to clean low-lying areas such as under sofas or coffee tables. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a double roller brush floor scrubber that can lie flat.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A reclining dual-brush floor scrubber includes a main unit and a floor brush pivotally connected to the bottom of the main unit. A front roller brush and a rear roller brush are arranged parallel to each other on the front and rear sides of the floor brush. A rotating seat pivotally connected to the bottom of the main unit is located between the front and rear roller brushes at the top of the floor brush. A clearance position is provided at the bottom of the main unit to avoid the rear portion of the floor brush. The rotating seat includes an upper tube pivotally connected to the bottom of the main unit and a lower tube rotatably connected to the floor brush. The axis of the lower tube intersects with the axis of the upper tube at an angle α. The end of the lower tube is located behind the upper tube and has hinge posts on its left and right sides to achieve a rotatable connection with the floor brush. Hinge holes are provided on the front and rear sides of the top of the upper tube. A hinge seat is provided at the bottom of the main unit, and the hinge seat has a hinge platform that engages with the hinge holes to allow the main unit to swing left and right.

[0006] The top of the floor brush is recessed to form a recessed groove for the rotating seat to be installed.

[0007] The hinge seat has a downward extending plate on its front side, and the recessed groove has a corresponding slot for the plate to be engaged.

[0008] The top of the main unit is also equipped with a handle, the back of which is flush with the back surface of the main unit.

[0009] The handle includes a grip portion and a handle rod. The handle rod includes an upper rod connected to the grip portion and a lower rod connected to the top of the main unit. The upper rod and the lower rod are rotatably connected by a folding mechanism. The upper rod can be bent towards the front of the main unit relative to the lower rod through the folding mechanism.

[0010] The folding mechanism includes an upper connecting sleeve and a lower connecting sleeve, which are respectively inserted into the lower end of the upper rod and the upper end of the lower rod. A rotating column and a rotating sleeve are provided between the upper connecting sleeve and the lower connecting sleeve, which are interlocked and arranged along the bending direction. A locking mechanism is also provided between the upper connecting sleeve and the lower connecting sleeve to restrict the bending of the upper rod relative to the lower rod.

[0011] The locking mechanism includes a movable trigger movably connected to the upper connecting sleeve and a locking fastener arranged on the lower connecting sleeve. The unlocking trigger can cooperate with the locking fastener to lock and restrict the relative movement of the upper connecting sleeve and the lower connecting sleeve, thereby restricting the bending movement of the upper rod relative to the lower rod.

[0012] The rotating seat is hollow inside, forming a channel for the suction pipe to pass through.

[0013] The lower tube of the rotating seat has through grooves on both the front and rear sides.

[0014] The beneficial effects of this utility model are as follows: The bottom of the main unit of this utility model is provided with a clearance position to avoid the rear part of the floor brush. At the same time, through the cooperation of a bent rotating seat, the main unit can be tilted backward so that the clearance position can fit into the outer contour of the rear part of the floor brush, thereby allowing the main unit to lie completely flat. This allows the dual roller brush floor cleaner to enter lower places such as under sofas or coffee tables for cleaning. In addition, the rotating seat can also be used to make the main unit swing left and right. The forward direction can be adjusted by swinging left and right when working normally or when lying flat.

[0023] Reference Figures 1 to 7 A reclining dual-brush floor scrubber includes a main unit 100 and a floor brush 200 pivotally connected to the bottom of the main unit 100. A front roller brush 210 and a rear roller brush 220 are arranged parallel to each other on the front and rear sides of the floor brush 200. A rotating seat 230, pivotally connected to the bottom of the main unit 100, is located at the top of the floor brush 200 between the front roller brush 210 and the rear roller brush 220. A clearance position 101 is provided at the bottom of the main unit 100 to avoid the rear portion of the floor brush 200. The rotating seat 230 includes an upper tube 231 pivotally connected to the bottom of the main unit 100 and a lower tube 232 rotatably connected to the floor brush 200. The axis of the lower tube 232 intersects the axis of the upper tube 231 at an angle α, which is between 110 degrees and 165 degrees. The lower tube 232 bends backward, with its end positioned behind the upper tube 231. Hinges 233 are located on both sides, allowing the lower tube 232 to rotate and connect with the floor brush 200. A bent rotating seat 230, in conjunction with an avoidance groove, forms a recess that fits onto the outer contour of the rear part of the floor brush 200, allowing the main unit 100 to lie completely flat. This enables the dual-roller floor scrubber to clean lower areas such as under sofas or coffee tables. The upper tube 231 has hinge holes 234 on its top front and rear sides. The main unit 100 has a hinge seat 110 at its bottom, with a hinge platform 111 that engages with the hinge holes 234, allowing the main unit 100 to swing left and right. The forward direction can be adjusted by swinging left and right during normal operation and when lying flat.

[0024] As a preferred embodiment of this utility model, such as Figure 6 As shown, the top of the floor brush 200 is recessed to form a recessed groove 201 for the rotating seat 230 to be movably installed. The rotating seat 230 is partially located in the recessed groove 201, allowing the main unit 100 and the floor brush 200 to be relatively compact, reducing the size of the machine. Furthermore, a positioning structure is arranged in the recessed groove 201. The positioning structure includes a locking plate 112 extending downward from the front side of the hinge seat 110 and a corresponding slot seat 202 provided in the recessed groove 201 for the locking plate 112. When the main unit 100 is in a standing position, the locking plate 112 is engaged in the slot seat 202, which provides a certain support for the standing main unit 100, making the main unit 100 more stable; on the other hand, it prevents the main unit 100 from swaying left and right in the standing position, enhancing the standing stability of the main unit 100.

[0025] like Figure 2 , Figure 3 as well as Figure 7 As shown, the top of the main unit 100 is also provided with a handle 300. The handle 300 includes a grip part 310 and a handle rod 320. The handle rod 320 is connected between the grip part 310 and the main unit 100. The user can hold the grip part 310 to control the floor scrubber to move forward and clean the floor. The back side of the grip part 310 of the handle 300 is flush with the back surface of the main unit 100, so as not to hinder the flat position of the main unit 100. The handle rod 320 includes an upper rod 321 connected to the grip part 310 and a lower rod 322 connected to the top of the main unit 100. The upper rod 321 and the lower rod 322 are rotatably connected by a folding mechanism. The upper rod 321 can be bent towards the front of the main unit 100 relative to the lower rod 322 through the folding mechanism. After the main unit 100 is flat, the upper rod 321 can be bent upward so that the user can operate the floor scrubber in the flat position without bending over excessively. Specifically, the folding mechanism includes an upper connecting sleeve 323 and a lower connecting sleeve 324. The upper connecting sleeve 323 and the lower connecting sleeve 324 are respectively inserted into the lower end of the upper rod 321 and the upper end of the lower rod 322. A rotating post 326 and a rotating sleeve 325 are provided between the upper connecting sleeve 323 and the lower connecting sleeve 324, which are interlocked and arranged along the bending direction. A constraint is also provided between the upper connecting sleeve 323 and the lower connecting sleeve 324 to limit the upper rod 321 relative to the lower rod 322. 2. A bending locking mechanism; the locking mechanism includes a movable trigger 327 movably connected to the upper connecting sleeve 323 and a locking clamping member 328 arranged on the lower connecting sleeve 324. The unlocking trigger can cooperate with the locking clamping member 328 to lock and restrict the relative movement of the upper connecting sleeve 323 and the lower connecting sleeve 324, thereby restricting the bending movement of the upper rod 321 relative to the lower rod 322. Pressing the upper end of the unlocking trigger will cause the unlocking trigger to flip and disengage from the clamping member to achieve unlocking.

[0026] Preferably, the rotating base 230 has a hollow interior forming a channel 235 for the suction pipe 240 to pass through. The suction pipe 240 connects to the interface at the bottom of the main unit 100 through the interior of the rotating base 230, eliminating the need for additional placement of the suction pipe 240. Furthermore, the lower part of the rotating base 230 has through grooves 236 on both the front and rear sides of the lower tube 232, allowing the suction pipe 240 to bend and deform, thus preventing the suction pipe 240 from getting stuck when the main unit 100 swings back and forth, which would cause the surface of the suction pipe 240 to be damaged.
