The present invention relates to a self-wrung mop.
In order to make a flat mop to squeeze water by itself many techniques have been developed and proposed in the past, such as China patent gazette Nos. ZL 200720192814.5, ZL 201220160635.4, ZL 201020144850.6 and ZL 201220188408.2. They all provide a self-wrung mop with a basic structure including a mop handle and a slidable wringing sleeve located thereon. The wringing sleeve is connected to a wringing head through a connection bar. The wringing head includes an opening with a wringing roller inside. A flat panel mop head can pass through the opening. Drawing the wringing sleeve upward the wringing roller can squeeze water contained in a mop cloth coupled on the flat panel mop head. The aforesaid self-wrung flat mop has a drawback: after the water is squeezed the flat mop cannot stand upright and the flat panel mop head has to leveled with the cleaning cloth laid on the floor surface. As a result, the cleaning cloth is difficult to be dried and also is prone to be dirty.
The primary object of the present invention is to provide a self-wrung flat mop that can be easily dried after the water has been squeezed and also is less likely to be smeared by dirt to overcome the shortcomings of the aforesaid conventional self-wrung mop.
To achieve the foregoing object the self-wrung flat mop according to the invention includes a mop handle, a flat panel mop head and an operation handgrip. The flat panel mop head is installed on a distal end of the mop handle and movable against the mop handle at a wringing state parallel with the mop handle and a use state perpendicular to the mop handle. The flat panel mop head at another side opposite to the mop handle includes a cleaning cloth located thereon. The operation handgrip is slidably installed on the mop handle and includes a movable portion coupled on the mop handle, a mask connecting portion extended integrally from the movable portion and a head connected to the mask connecting portion. The head includes a first passage run through by the mop handle, a second passage run through by the flat panel mop head, a squeezing portion corresponding to the second passage to allow the flat panel mop head to pass through and to squeeze water from the cleaning cloth, and a support plane at one end remote from the movable portion. The self-wrung flat mop has an upright holding state with the flat panel mop head entered the wringing state without overextending the support plane so that the support plane can rest on a floor surface.
In one aspect the mop handle includes a guide block, and the handgrip includes a directing portion extended from the mask connecting portion and the head to guide movement of the guide block.
In another aspect the directing portion includes two ends each being a confining end.
In yet another aspect the directing portion includes at least one positioning bulged spot.
In yet another aspect the second passage includes two guide ribs at one side remote from the cleaning cloth. Each guide rib is in contact with one side of the flat panel mop head where the cleaning cloth is not located thereon.
In yet another aspect the squeezing portion includes a scrape strip holder, a squeezing strip located on the scrape strip holder facing the cleaning cloth and a scrape strip holder spring located on the scrape strip holder to push the squeeze scrape strip to press toward the cleaning cloth.
In yet another aspect the squeezing portion includes a brush base, a brush located on the brush base to face the cleaning cloth and a brush base spring located on the brush base to push the brush to press toward the cleaning cloth.
In yet another aspect the head includes a scrape strip holder opening and a brush base opening corresponding to the squeezing portion. The scrape strip holder opening includes a scrape strip holder detent rib on an inner rim at one end faced the cleaning cloth. The scrape strip holder includes a scrape strip holder detent flange confined by the scrape strip holder detent rib. The brush base opening includes a brush base detent rib on an inner rim at one end faced the cleaning cloth. The brush base includes a brush base detent flange confined by the brush base detent rib. The head includes a detent lid located at one side of the scrape strip holder opening and the brush base opening remote from the cleaning cloth for installation of the scrape strip holder spring and the brush base spring to confine the scrape strip holder and the brush base.
In yet another aspect the scrape strip holder includes a wedge trough and the squeezing scrape strip includes a rotary shaft located in the wedge trough.
In yet another aspect the squeezing portion includes an installation base, a brush and a squeezing scrape strip located on the installation base and faced the cleaning cloth, and at least one installation base spring located on the installation base.
In yet another aspect the head includes an installation base opening corresponding to the squeezing portion that includes an installation base detent rib located on an inner rim at one side faced the cleaning cloth. The installation base includes an installation base detent flange confined by the installation base detent rib. The head includes a detent lid located at one side of the installation base opening remote from the cleaning cloth for installation of the installation base spring to confine the installation base.
In yet another aspect the flat panel mop head includes at least one latch opening at one end thereof and at one side where the cleaning cloth is not located. The self-wrung flat mop includes a cloth clamp plate hinged on the latch opening and installed on the flat panel mop head. The cloth clamp plate is latched on the latch opening via a latch lug.
The invention thus formed can provide many advantages, such as: 1. After water is squeezed the entire mop (including the flat panel mop head) can be positioned upright to facilitate drying of the cleaning cloth located on the flat panel mop head without in contact with the floor surface and getting smeared by dirt; 2. The guide block can serve as a directing means to facilitate sliding up and down of the operation handgrip and the head; 3. The flat panel mop head is guided during squeezing, and can be prevented from toppling via the guide rib; 4. The squeezing scrape strip and the brush can be adjusted automatically during squeezing according to the thickness and dirty degree of the mop; and 5. The cleaning cloth can be installed simply without loosening away easily.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

The head 4 of the operation handgrip 3 is extended transversely to form a support plane 42. When the head 4 is at the lower position it also functions as a base so that the lower end of the flat panel mop head 2 in parallel with the mop handle 1 can be inserted into the slot 5 to enable the mop (i.e., the self-wrung flat mop) to be positioned in an upright manner, namely, the self-wrung flat mop allows the flat panel mop head 2 to enter the wringing state without overextended the support plane 42 of the operation handgrip 3 so that the support plane 42 can be rested on a floor surface to keep the self-wrung flat mop in an upright manner.
In this embodiment the operation handgrip 3 further includes a movable portion 31 coupled on the mop handle 1 and a mask connecting portion 32 integrally extended from the movable portion 31. Furthermore, the mask connecting portion 32 is connected to the head 4 and can include two connection strips 6 on the left side and the right side. The mask connecting portion 32 and the head 4 also can be integrated to form a firmer structure. The mask connecting portion 32 can further include an installation ornamental cap 28 between the two connection strips 6 on the left side and the right side to make the appearance more appealing. In addition, the mask connecting portion 32 can further include a guide block 7 which is extended to the left side and the right side to form respectively a directing wing 8. The operation handgrip 3 includes a directing portion extended to the mask connecting portion 32 and the head 4 to direct movement of the guide block 7. More specifically, the directing portion is two sets of positioning strips 9 extended from the connection strips 6 below the directing wing 8 so that the directing wings 8 and the positioning strips 9 can be collaborated to facilitate movement of the guide block 7 against the operation handgrip 3 and the head 4 to make sliding of the operation handgrip 3 and the head 4 smoother in a desired direction. In addition, the directing portion comprises two ends formed respectively a confining end. When the head 4 is at the lower position the lower end surface of the operation handgrip 3 can be hung on the guide block 7 to be confined thereof. In addition, when the head 4 is at the lower position the lower end surface of the operation handgrip 3 also can be unhung from the guide block 7 with the head 4 resting on the floor surface to hold the operation handgrip 3 and the head 4 in one set.
In another embodiment, when the head 4 is slid to the higher position the head 4 and the operation handgrip 3 are anchored via a positioning mechanism. The positioning mechanism includes at least one positioning bulged spot 10 on the directing portion. More specifically, the positioning bulged spot 10 is located on a lower end of the connection strip 6 so that when the head 4 is at the higher position the positioning bulged spot 10 presses the backside of the directing wing 8. When the operation handgrip 3 slides upward and the head 4 is located at the higher position the positioning bulged spot 10 on the connection strip 6 presses the backside of the directing wing 8 of the guide block 7 in a frictional and compressed manner so that the operation handgrip 3 and the head 4 can be anchored without sliding down. For using the next time, move the operation handgrip 3 and the head 4 downward forcefully. Of course, other positioning mechanisms also can be adopted, such as insertion pins, positioning bulged spots on the mop handle 1, and forming a positioning hole on the operation handgrip 3 so that when the operation handgrip 3 reaches the higher position the positioning bulged spot can latch in the positioning hole.
