[0029] See Figure 1 , Figure 2 and Figure 3This invention provides a mop, including a mop handle 1 and a mop head 2 mounted on the handle 1. A plurality of mop blades 3 are provided at the bottom of the mop head 2, which can expand at the bottom of the mop head 2. An expansion device 4 is provided on the mop head 2 to drive the mop blades 3 to expand. Specifically, holding the mop handle 1 allows the mop head 2 to mop the floor. The expansion device 4 can open the mop blades 3 to increase the original mopping area. When the mop blades 3 are retracted, they can be placed in a smaller area for convenience. Furthermore, the mop area can be adjusted according to the mopping environment, allowing for large-area mopping, saving time and effort.

[0030] See Figure 3 and Figure 4 In an optional embodiment, the bottom surface of the mop head 2 is circular or nearly circular. The mop blades 3 are brought together to form a circular or nearly circular shape, and when opened, they form a petal shape with the mop head 2.

[0031] See Figure 8 In an optional embodiment, the expansion device 4 includes an expansion claw 41 and a rotating frame 42 mounted on the expansion claw 41. Specifically, the expansion claw 41 is installed inside the mop head. When the rotating frame 42 rotates, it can cause the expansion claw to open, thereby opening the mop blades.

[0032] See Figure 8 In an optional embodiment, the expanding claw 41 includes a turntable 411 mounted on a rotating frame 42. Connecting rods 412 are evenly distributed around the turntable 411, with the ends of the connecting rods 412 connected to the drag plates 3. Specifically, when the turntable 411 rotates, the connecting rods 412 spread radially outward, thereby opening the drag plates 3. The turntable 411 has multiple protrusions distributed on its outer circumference, which can reduce the weight of the expanding claw 41.

[0033] See Figure 8 In an optional embodiment, spring buttons 421 are symmetrically provided on the rotating frame 42. The rotating frame 42 is hinged to the mop handle 1. Specifically, the spring buttons 421 can be engaged with the mop head 2 so that the mop blades 3 will not automatically retract after opening. The hinge between the rotating frame 42 and the mop handle 1 facilitates the rotation of the mop handle 1, making mopping more convenient.

[0034] See Figure 7In an optional embodiment, a rear cover 21 is provided on the mop head 2, and a cylindrical shell 211 is provided on the rear cover 21. Symmetrical fixing protrusions 212 are provided on the side of the cylindrical shell 211, and several pairs of radially penetrating locking holes 213 are also provided on the cylindrical shell 211. Each pair of locking holes 213 is used to fix the spring button 421. Specifically, the rear cover 21 seals the expansion claw 41 inside the mop head 2, protecting the expansion claw 2. There are two pairs of locking holes 213: one pair fixes the mop piece 3 when it is retracted, and the other pair fixes the mop piece 3 when it is open. Multiple pairs of locking holes 213 can also be provided to accommodate different opening areas of the mop piece 3. To change the mop piece 3 from a closed state to an open state, simply press the spring button 421, then rotate the turntable 411 to lock the spring button 421 into another pair of locking holes 213.

[0035] See Figure 7 In an optional embodiment, the mop head 2 is further provided with an arc-shaped guide rail 22 for controlling the movement trajectory of the mop blade 3. Specifically, the arc-shaped guide rail 22 prevents interference when the mop blade 3 is open.

[0036] See Figure 6 and Figure 7 In an optional embodiment, the mop head 3 is triangular in shape, comprising two arcuate protrusions and one concave protrusion. The middle position of the concave protrusion of the mop head 3 is connected to the expansion device 4. One end of the mop head 3 is rotatably connected to the mop head 2.

[0037] See Figure 5 In an optional embodiment, the mop handle 1 is further provided with a fixing seat 11. A movable sleeve 12 is also connected to the mop handle 1, which can move up and down and be fixed on the fixing seat 11. Specifically, when the movable sleeve 12 is at its highest position, it can be fixed on the fixing seat, generally by a threaded connection. When the movable sleeve 12 moves down, it covers the back cover 21, preventing the spring button 421 from being stuck by the original locking hole 213, and the mop pad 3 is opened after rotating the turntable 411.

[0038] See Figure 5 In an optional embodiment, the bottom of the movable sleeve 12 is provided with a hollow shell 121 that matches the rear cover 21. Specifically, the internal shape of the hollow shell 121 matches the external shape of the protruding part on the rear cover 21. When the hollow shell 121 covers the protruding part on the rear cover 21, pressing the spring button 421 into place prevents it from being stuck by the original locking hole 213. After rotating the turntable 411, the mop piece 3 is opened and locked by another pair of locking holes 213. Pulling the movable sleeve 12 upwards allows the mop to continue to be used, making adjustment more convenient.

[0039] See Figure 4When the three mop blades are held together, gaps will form. These gaps can trap debris and hair while mopping, making it easier to collect and remove them later.

[0040] See Figure 5 The top of the mop head 2 also features a curved section. The curved section makes it easy to hold and mop with one hand.

[0041] See Figure 6 The mop head at the bottom of mop pad 3 is removable, making it easy to remove for hand washing or replacement. When the mop head is made of a hard material such as foam, it can be directly inserted into the bottom of mop pad 3. When the mop head is made of a soft material such as cloth strips, it can be fixed to the notch at the top of mop pad 3.

[0042] Specific usage process:

[0043] With the mop blades 3 in the closed position, move the movable sleeve 12 up and onto the fixed base 11. Hold the curved part at the top of the mop head 2. The mop handle 1 is hinged to the mop head 2. The mop handle 1 can rotate around the mop head 2 at an appropriate angle, making it easy to find the optimal angle for mopping. The bottom of the mop head 2 is round, and the mop blades 3 cover the bottom of the mop head 2 when closed. There are gaps between the mop blades 3 when closed, which can trap hair and other small debris when mopping. The gaps are also designed for drainage, allowing space for debris to move around and preventing it from scratching the floor and tiles if it cannot move.

[0044] Moving the movable sleeve 12 downwards allows the hollow housing 121 to cover the cylindrical housing 211, preventing the spring button 421 from being stuck by the original locking hole 213. Rotating the mop handle 1 will rotate the turntable 411, opening the mop blade 3. Once locked by another pair of locking holes 213, the mop blade 3 is in an unfolded state, increasing the mopping area. When there are multiple pairs of locking holes 213, the mop blade 3 can be expanded to different areas.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
