[0057] Figure 1-Figure 4 As shown, when the flat mop needs to be used for scrubbing and cleaning, the user pushes the knob portion 3 downward to make the lock member 19 drive the linkage member 21 to move downward, pushes the linkage member 21 down to the lower position, and moves the flat mop head 4 stored in the accommodating cavity 39 out of the hidden sleeve 1. At this time, the lower stop portion 18 is in the lock groove 20, and the knob portion 3 is rotated to rotate the lock member 19 until the inner groove walls 54 opposite to each other on both sides of the lock groove 20 are located at the upper and lower sides of the lower stop portion 18, locking the relative movement of the linkage member 21 and the hidden sleeve 1, positioning the linkage member 21 at the lower position, and flipping the flat mop head 4 to the horizontal direction. The user can then hold the handle portion 31 to wipe and clean.

[0058] When it is necessary to clean and squeeze water from the wiping portion of the flat mop head 4 after cleaning, the knob portion 3 is rotated to rotate the lock member 19 until the two side notches of the lock groove 20 are located at the upper and lower sides of the lower stop portion 18 to achieve unlocking. At this time, the linkage member 21 can slide up and down relative to the hidden sleeve 1, and the flat mop head 4 is flipped upward to a vertical direction parallel or quasi-parallel to the connecting rod 5. The flat mop head 4 faces the first opening 42 at the lower part of the accommodating chamber 39, and the linkage member 21 is driven up and down by the knob portion 3 to make the flat mop head 4 move up and down through the squeezing channel 8. During the process of the flat mop head 4 moving up and down in the squeezing channel 8, the squeezing component 7 squeezes water from the wiping portion on the flat mop head 4.

The knob portion 3 drives the linkage member 21 to move up to the upper position, so that the flat mop head 4 is completely hidden in the accommodating cavity 39. At this time, the upper stop portion 25 is located in the lock groove 20. The knob portion 3 is rotated to rotate the lock member 19 until the inner groove walls 54 opposite to each other on both sides of the lock groove 20 are located at the upper and lower sides of the upper stop portion 25, locking the relative movement of the linkage member 21 and the hidden sleeve 1, positioning the linkage member 21 at the upper position, and completing the storage.

[0060] Compared with the existing self-squeezing horizontal flat mop, the flat mop replaces the traditional mop rod with a hidden sleeve 1 and a connecting rod 5 extending out of the hidden sleeve 1. The maximum length of the flat mop when in use is only slightly larger than the hidden sleeve 1, and the overall volume is smaller, which is convenient for the operator to clean windows, kitchen countertops, desktops or family cars with one hand. It is more practical and has a wide range of applications. When the flat mop head 4 is stored as a whole in the hidden sleeve 1, the volume becomes smaller than when in use, which is convenient for users to carry. The flat mop head 4 is hidden in the hidden sleeve 1, which can effectively reduce the pollution of the flat mop head 4 by external dust during storage, and is more suitable for the storage of the flat mop head 4. Since the flat mop head 4 is hidden in the hidden sleeve 1, the hidden sleeve 1 can open downward and stand vertically on a plane. A squeezing mechanism is provided on the hidden sleeve 1, which can drive the flat mop head 4 to move up and down through the linkage 21 so that the squeezing mechanism squeezes water from the wiping part on the flat mop head 4.

When the flat-plate mop head 4 rotates to be parallel or quasi-parallel with the connecting rod 5, the hinge seat 12 on one side of the top of the flat-plate mop head 4 is inserted into the limiting groove 14, and the lock core 16 is inserted into the gear groove 15. The limiting groove 14 cooperates with the hinge seat 12 to limit the rotation of the flat-plate mop head 4 around the hinge axis 11, and the lock core 16 is inserted into the gear groove 15 to limit the rotation of the flat-plate mop head 4 around the hinge axis 2 13, so that when the flat-plate mop head 4 is flipped to be parallel or quasi-parallel with the connecting rod 5, the movement is not easy to deflect and is more stable.

[0062] The lower end of the connecting rod 5 is provided with a movable cavity 17 which opens downwards for the lock core 16 to move up and down therein.

[0063] In addition, an elastic member is provided between the linkage member 21 and the hidden sleeve 1. When the locking mechanism is unlocked, the elastic force of the elastic member drives the linkage member 21 to move and reset to the lower position, so that the flat mop head 4 can be automatically moved out of the accommodating cavity 39 when the flat mop is used, which is convenient for use.

[0064] Figure 3 , Figure 6 As shown, preferably, the elastic member is a reset spring 26, and the linkage member 21 is connected to a support rod 22 for supporting the reset spring 26.
