Technical Field
[0001] This invention relates to the field of daily necessities technology, and discloses a step-type mop. Background Technology
[0002] Currently, the invention patent with patent number 202310805977X relates to a cleaning tool and its cleaning bucket, but the cleaning mechanism of the cleaning tool is complex and the production cost is high. Summary of the Invention
[0003] This invention addresses the problems existing in the prior art by providing a step-type mop, which effectively solves the shortcomings of the prior art.
[0004] The present invention adopts the following technical solution:
[0005] A step-type mop includes a roller (1), an elastic guide rod (5), a body (6), a squeegee ring (7), a handle (8), and a push rod (9). The body provides support for the entire mop, acting as a frame. It is also provided with a body protrusion (6-1) for mounting the roller, a track (6-2), an elastic guide rod mounting hole (6-3), and an elastic guide rod limiting groove (6-4). The roller is mounted on the body, and its outer surface is covered with a mop cloth (1-1). One end is fixed with a flange (1-2) and pivotally connected to a roller fixing cover (1-3). The other end is fixed with an end cover (1-4) and pivotally connected to a cylindrical bearing (1-6). The end face of the end cover (1-4) is provided with several evenly distributed guide grooves (1-5). Of course, the guide grooves can also be set on the cylindrical surface of the end cover. There may be a drop at the turning point between two adjacent approximately straight guide grooves, or there may be no drop. The elastic guide rod (5) is pivotally connected to the elastic guide rod mounting hole (6-3) of the main body (6). Its rotation range is limited by the elastic guide rod limiting groove (6-4) on the main body. Its cylindrical pin (5-1) slides in the guide groove of the end cover (1-4) due to the elastic effect. Due to the drop at the turning point, the cylindrical pin (5-1) can only move forward in the guide groove and cannot move backward. When mopping, due to the pushing and pulling motion, the cylindrical pin (5-1) sometimes slides from one turning point position to another turning point position in the guide groove and stops. After stopping, it continues to slide to the next turning point position and stops. This process is repeated to achieve the unidirectional stepping rotation of the roller. For example, when pulling backward, the cylindrical pin (5-1) slides from the turning point position M (2) to the turning point position N (3) in the guide groove. At this time, due to the drop, the cylindrical pin (5-1) suddenly sinks and stops, and the roller is restricted and cannot rotate. When pushed forward, the cylindrical pin (5-1) slides from the guide groove inflection point N(3) to the guide groove inflection point P(4). Due to the drop, the cylindrical pin (5-1) suddenly sinks and stops, and the roller is restricted and cannot rotate. If there is no drop at the guide groove inflection point, when pulled backward, the cylindrical pin (5-1) smoothly moves from the guide groove inflection point M(2) to the guide groove inflection point N(3), stops, and the roller is restricted and cannot rotate. When pushed forward, the cylindrical pin (5-1) smoothly moves from the guide groove inflection point N(3) to the guide groove inflection point P(4), stops, and the roller is restricted and cannot rotate. If the installation positions of the guide groove and the elastic guide rod are interchanged, with the evenly distributed guide grooves set on the body and the elastic guide rod pivotally connected to the end cover, the roller can also achieve unidirectional stepping rotation. The handle (8) is pivotally connected to the body (6), and the push rod (9) is sleeved on the handle (8) and can move along the handle axis. The front end of the push rod (9) is provided with two push rod vertical protrusions (9-1) and two push rod flat protrusions (9-2).The squeegee ring (7) has a circular ring (7-2) that fits onto the outer cylindrical surface of the roller. Normally, it can be held at one end of the roller by the attraction of a magnet or similar object. It can move along the roller axis to remove water stains from the roller. It has two squeegee ring grooves (7-1). When squeegeeing is needed, the handle is placed along the length of the mop. At this time, the two vertical protrusions (9-1) at the front end of the push rod (9) enter the squeegee ring grooves (7-1), and the two flat protrusions (9-2) are ready to enter the main body track (6-2). When the push rod is pushed, the flat protrusions enter the main body track and slide along the main body track. The vertical protrusions of the push rod take the squeegee ring (7) away from the resting position. The squeegee ring moves back and forth with the push rod to achieve squeegeeing. After squeegeeing is completed, the push rod drives the squeegee ring back to one end of the roller, which is the starting position of the squeegee ring. If the end face of the roller end cap (1-4) described in the above technical solution does not have a guide groove, but instead has several evenly distributed ratchet grooves (1-7) on the cylindrical surface of the end cap, and the body is not pivotally connected with an elastic guide rod, then as long as a one-way pin (10) with a return spring is pivotally connected to the body to control the roller and make it rotate in one direction, with the help of pushing or pulling force, it can be achieved that when pushing or pulling, one roller rotates while the other roller is locked. In this way, the mop roller can maintain a certain friction with the ground instead of pure rolling, thus making it easier to wipe away dirt on the ground. Afterwards, the water stains remaining on the roller after cleaning can be scraped off with the help of the squeegee.
[0006] The significant technical feature of this solution is the cooperation between the guide groove of the roller end cover and the elastic guide rod pivotally connected to the main body. With the help of the pushing and pulling force when mopping, the roller can be controlled to achieve unidirectional stepping rotation.
[0007] This design effectively overcomes the main shortcomings of existing technologies.
[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: simple and novel structure, convenient operation, low cost, and very practical. Attached Figure Description

[0024] Example 1:
[0025] A step-type mop includes a roller (1), an elastic guide rod (5), a body (6), a squeegee ring (7), a handle (8), and a push rod (9). The body provides support for the entire mop, acting as a frame. It is also provided with a body protrusion (6-1) for mounting the roller, a track (6-2), an elastic guide rod mounting hole (6-3), and an elastic guide rod limiting groove (6-4). The roller is mounted on the body, and its outer surface is covered with a mop cloth (1-1). One end is fixed with a flange (1-2) and pivotally connected to a roller fixing cover (1-3). The other end is fixed with an end cover (1-4) and pivotally connected to a cylindrical bearing (1-6). The end cover (1-4) has several evenly distributed guide grooves (1-5) on its end face. Of course, the guide grooves can also be set on the cylindrical surface of the end cover. There is a drop between two adjacent approximately straight guide grooves at the turning point. The elastic guide rod (5) is pivotally connected to the elastic guide rod mounting hole (6-3) of the body (6). Its rotation range is limited by the elastic guide rod limiting groove (6-4) on the body. Its cylindrical pin (5-1) slides in the guide groove of the end cover (1-4) due to the elastic effect. Due to the drop at the turning point, the cylindrical pin (5-1) can only move forward in the guide groove and cannot move backward. When mopping, due to the pushing and pulling motion, the cylindrical pin (5-1) sometimes slides from one turning point position to another turning point position in the guide groove and stops. After stopping, it continues to slide to the next turning point position and stops. This process is repeated to realize the unidirectional stepping rotation of the roller. The handle (8) is pivotally connected to the body (6). The push rod (9) is sleeved on the handle (8) and can move along the handle axis. The front end of the push rod (9) is provided with two push rod vertical protrusions (9-1) and two push rod flat protrusions (9-2). The squeegee ring (7) has a circular ring (7-2) that fits onto the outer cylindrical surface of the roller. Normally, it can be held at one end of the roller by the attraction of a magnet or similar object. It can move along the roller axis to remove water stains from the roller. It has two squeegee ring grooves (8-1). When squeegeeing is needed, the handle is placed along the length of the mop. At this time, the two vertical protrusions (9-1) at the front end of the push rod (9) enter the squeegee ring grooves (7-1), and the two flat protrusions (9-2) are ready to enter the main body track (6-2). When the push rod is pushed, the flat protrusions enter the main body track and slide along the main body track. The vertical protrusions of the push rod take the squeegee ring (7) away from the resting position. The squeegee ring moves back and forth with the push rod to achieve squeegeeing. After squeegeeing is completed, the push rod drives the squeegee ring back to one end of the roller, which is the starting position of the squeegee ring.
