[0002] Currently available mops are generally used for cleaning large areas. However, when cleaning small spaces such as household toilets and bedroom gaps, the space is narrow and difficult to clean, so existing mops cannot clean thoroughly. Therefore, it is necessary to design a mini mop that is small in size and can easily enter and exit small spaces such as gaps. The mini mop is required to be energy-saving and environmentally friendly, and can use used non-woven towels or disposable dissolvable cleaning paper towels as cleaning consumables.

[0003] Conventional mini mops all have the following drawbacks: sponge mini mops have low cleaning effect, and dirt left on the sponge will become moldy after multiple uses; paper mini mops require hands to touch the paper towel when attaching or removing it, which is inconvenient and may expose hands to contaminants; and both hands must be used to remove the paper towel, making the operation somewhat cumbersome.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The present invention will be described in more detail and completely below with reference to the drawings and specific embodiments. It is clear that the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature, and is not intended to limit the present invention and its application or use in any way. All other embodiments obtained by those skilled in the art based on the embodiments in the present invention without creating new ideas all belong to the scope of the present invention.

[0016] The push-type mop rod assembly of the present invention is used in a mini mop, and as shown in Figures 1 to 4, includes a return mechanism 3, the return mechanism 3 includes an outer push rod 3-1 and a connecting rod 3-3 that is arranged inside the outer push rod 3-1 and can move up and down. A position control member and a return member for releasing the position control of the position control member are further provided between the connecting rod 3-3 and the outer push rod 3-1. The upper and lower ends of the connecting rod 3-3 are respectively connected to the mop rod 1 and the transmission assembly 4. The transmission assembly 4 can drive the telescopic wings 5 ​​on both sides of the mop plate 2 to extend outward or contract inward by the up and down movement of the connecting rod 3-3, thereby realizing the function of attaching and removing paper towels.

[0017] The mop plate 2 includes an upper cover 2-1 and a lower cover 2-2, and a space is formed between the upper cover 2-1 and the lower cover 2-2 to accommodate the transmission assembly 4. The lower cover 2-2 has a guide groove that slidably fits with the guide block on the telescopic wing 5, so as to ensure the stability of the movement process of the telescopic wing 5. The bottom of the lower cover 2-2 and the bottom of the telescopic wing 5 are both provided with a non-slip rubber coating layer 6, which can not only provide a cushioning effect but also ensure the cleaning effect.

[0018] The position restricting member includes a position restricting locking member 3-4 provided on the connecting rod 3-3 and a locking groove provided on the outer push rod 3-1 to fit with the position restricting locking member 3-4. One end of the position restricting locking member 3-4 is hingedly connected to the connecting rod 3-3 and the other end is engaged with the locking groove by the action of a snap spring 3-5. The return member includes a return press sleeve 3-2 provided on the outer push rod 3-1 and a return spring 3-6 whose both ends abut against the connecting rod 3-3 and the outer push rod 3-1, respectively. The return spring 3-6 is provided coaxially with the connecting rod 3-3 and the outer push rod 3-1. A pressing protrusion is provided at a position corresponding to the locking groove of the pressing sleeve 3-2. Furthermore, the snap spring 3-5 is horizontally provided on the side of the position restricting locking member 3-4 away from the pressing protrusion, and the snap spring 3-5 and the return spring 3-6 are perpendicular to each other. The position restricting locking member 3-4 overcomes the elastic force of the snap spring 3-5 under the pressure action of the pressing protrusion and contracts inwardly, so as to be able to disengage from the locking groove of the outer push rod 3-1. At the same time, when the position restricting locking member 3-4 disengages from the locking groove, the connecting rod 3-3 can be displaced upward by the action of the return spring 3-6.

[0019] The outer push rod 3-1 is rotatably connected to the mop plate 2 through the first rotary joint 3-7 and the second rotary joint 3-8 in sequence, that is, the outer push rod 3-1 is rotatably connected to the second rotary joint 3-8 through the first rotary joint 3-7, and the second rotary joint 3-8 is also rotatably connected to the mop plate 2, and the rotation direction of the first rotary joint 3-7 is perpendicular to the rotation direction of the second rotary joint 3-8, thereby realizing forward / backward and left / right rotation; between the connecting rod 3-3 and the transmission assembly 4, the outer push rod 3-1 rotates according to the first rotary joint 3-7 and the second rotary joint 3-8. A third rotary joint and a fourth rotary joint are provided, and when the connecting rod 3-3 is displaced downward and in a position restricted state, that is, when the telescopic wings 5 ​​on both sides are tightened, the third rotary joint and the fourth rotary joint can rotate together with the first rotary joint 3-7 and the second rotary joint 3-8; when the connecting rod 3-3 is displaced upward and in a position restricted release state, that is, when the telescopic wings 5 ​​on both sides are unfolded, the third rotary joint and the fourth rotary joint are misaligned with the first rotary joint 3-7 and the second rotary joint 3-8, thereby realizing the self-supporting function of the mop rod and facilitating its use and storage.

[0020] The principle of use of the mini mop using the pressing type mop rod assembly of the present invention is as follows: In the initial state, the telescopic wings 5 ​​on both sides of the mop plate 2 are in a tightened state. At this time, one finger of one hand presses the pressing protrusion on the return press sleeve 3-2 inwardly, and presses the position-regulating locking member 3-4 to overcome the acting force of the snap spring 3-5 and compress it inwardly, so that the position-regulating locking member 3-4 is released from the locking groove of the outer push rod 3-1. The connecting rod 3-3 is displaced upwardly by the acting force of the return spring 3-6, driving the third rotary joint and the fourth rotary joint to be displaced upwardly, and at the same time, the transmission assembly 4 at the bottom is interlocked, so that the telescopic wings 5 ​​are deployed on both sides respectively, and the paper towel is attached; In the deployed state of the telescopic wing 5, the mop rod 1 applies downward pressure, pushing the connecting rod 3-3 to overcome the elastic force of the return spring 3-6 and displace it downward. The connecting rod 3-3 drives the third rotary joint and the fourth rotary joint to displace downward, and at the same time engages the bottom transmission assembly 4. The telescopic wing 5 is respectively tightened to the middle, and the connecting rod 3-3 displaces downward to the position limiting locking member 3-4 and engages in the locking groove of the outer push rod 3-1, thereby realizing the position lock. At the same time, the paper towel is in the installed state, and at this time, the mop can be dragged to achieve the cleaning effect; After cleaning is completed, the above-mentioned finger of one hand can repeatedly press the pressing protrusion on the return sleeve 3-2 inward, thereby realizing the deployment of the telescopic wings 5 ​​to both sides, and the dirty paper towel will fall into the trash can or toilet bowl under the action of gravity, and the paper towel will be automatically removed, preventing the hands from touching the dirty paper towel and greatly improving the user's operability.

[0021] The above description is merely a preferred specific embodiment of the present invention, and does not limit the scope of the claims of the present invention. Any equivalent replacement or modification made by a person skilled in the art based on the technical solutions of the present invention and the concept of the invention within the technical scope disclosed in the present invention should be included in the scope of the claims of the present invention.
