Technical Field

The invention relates to a cleaning tool, in particular to a cleaning tool suitable for cleaning and drying a foam cotton mop, wherein the foam cotton is a wiping material made by a foam molding process, and can be collodion cotton, sponge, a wiping material made of synthetic materials containing the foam cotton or the like.

Background

The traditional collodion mop comprises a mop rod, a mop head and a water squeezing mechanism, wherein the water squeezing device in the collodion mop is a transmission structure and comprises a handle, a pull rod, a caliper seat (squeezing frame), a collodion clamp and a water squeezing rod, the caliper seat is approximately U-shaped, the collodion clamp is clamped by the collodion clamp, the collodion clamp is fixed at the bottom end of the pull rod, the top end of the pull rod is movably pinned with the middle part of the handle, the rear end of the handle is pinned on the mop rod, and the two ends of the water squeezing rod are pinned at the lower end of the caliper seat. When the wringing operation is performed, the pulling handle is pulled to drive the collodion head to move up horizontally through the pulling rod, and the wringing rod wrings water from the upper part to the lower part in the thickness direction of the collodion. The mop rod of the mop is additionally provided with a plurality of components, and has complex structure, heavy weight and laborious operation.

Some inventions are directed to a cleaning barrel of a collodion mop, such as the Chinese patent application with the application number of CN201710920255.3, namely a cleaning barrel and a collodion mop for cleaning the collodion mop, and the Chinese patent application with the application number of CN201811267670.4, namely a collodion mop squeezing barrel, and the like. A squeezing device is arranged on the barrel body, and a squeezing part in the squeezing device squeezes the bottom surface of the foaming cotton head only along the length direction of the foaming cotton head. The water squeezing stroke is long (longer than the mop head), the time consumption is high, the height of the cleaning barrel must be increased, the cost is increased, the mop head needs to be rotated to be basically parallel to the mop rod during water squeezing, and the operation is inconvenient.

Therefore, how to design a cleaning tool for a foam cotton mop, which has a small and reasonable structure, low cost and capability of being quickly squeezed, is a problem to be solved by the technical personnel in the field.

Disclosure of Invention

The invention aims to solve the technical problem of providing a cleaning tool based on a foam cotton mop, which has a brand-new water squeezing mode, a simple and reasonable structure, low cost and capability of quickly squeezing water, aiming at the current situation of the prior art.

The technical scheme adopted by the invention for solving the technical problems is as follows: a cleaning tool for a foam cotton mop comprises a cleaning barrel and the mop, wherein the mop comprises a mop head connected to the lower end of a mop rod, the mop head comprises an installation part and foam cotton arranged at the bottom of the installation part, and the cleaning barrel is provided with a water squeezing structure for squeezing the foam cotton; the method is characterized in that: the squeezing structure comprises two squeezing parts which are oppositely arranged at left and right intervals, a squeezing channel can be formed between the two squeezing parts when squeezing water, and the minimum distance between the squeezing channels is smaller than the width of the foamed cotton; the foamed cotton is provided with a first extruded surface and a second extruded surface which extend along the length direction, the first extruded surface and the second extruded surface are respectively positioned at the left side and the right side of the central axis of the foamed cotton, the first extruded surface is provided with a first lower extruded position and a first upper extruded position, and the second extruded surface is provided with a second lower extruded position and a second upper extruded position; when squeezing water, the length direction of the squeezing component and the length direction of the foam cotton are both transverse, and in the process of pressing the mop rod downwards, the squeezing component firstly contacts and squeezes with the first lower squeezing position and the second lower squeezing position and gradually transits to contact and squeeze with the first upper squeezing position and the second upper squeezing position.

As an improvement, at least one of the extrusion parts can rotate around the axis of the extrusion part, and the foaming cotton drives the extrusion parts to rotate in the process of pressing down the mop rod. The rotation of the pressing member is a rotation around a rotation axis within a certain angle range, and the certain angle range may be 360 degrees, or a rotation smaller than 360 degrees (similar to a swing) such as 180 degrees or 90 degrees. The mop moves downwards, the foam cotton is contacted with the squeezing part and moves downwards, the squeezing part is driven by friction force to rotate inwards around the axis of the squeezing part, the squeezing part rotating inwards generates force for pushing the foam cotton to the lower part of the squeezing channel, and the foam cotton is squeezed into the squeezing channel more easily. Of course, one of the pressing members may be fixed so as not to rotate about its own axis, and the other pressing member may be rotatable about its own axis.

In a further improvement, at least one section of the first extruded surface between the first lower extruded position and the first upper extruded position expands outwards from bottom to top. Preferably stepwise outwardly. Therefore, in the wringing process, the foaming cotton at least forms a section of small and large cross section structure from bottom to top, so that the foaming cotton is more easily squeezed into the squeezing channel, meanwhile, the foaming cotton is more fully squeezed from bottom to top, and the wringing effect is better.

Of course, if at the same time at least one section of the second pressed surface between the second lower pressed position and the second upper pressed position expands from bottom to top. It is more preferable. Preferably stepwise outwardly.

Preferably, the two pressing members can rotate around the axes of the two pressing members, and the pressing members are pressing rollers with circular cross sections. Because of the squeeze roll is circular roll form for no matter the squeeze roll is rotatory to that position state, all the time be the cambered surface with the cotton contact surface of foaming, the extrusion contact between extrusion part and the foaming cotton is the cambered surface contact, makes the extrusion part be difficult for damaging the foaming cotton at crowded water in-process, does not have the requirement to the direction of assembly moreover, does benefit to the assembly, need not additionally to set up reset structure. In addition, the surface of the extrusion part, which is in contact with the foam cotton, is a cambered surface, so that the extrusion channel is of a structure with a large upper part and a small lower part, and water extrusion is facilitated. The rotating squeezing part can enable the foaming cotton to be squeezed into the squeezing channel more easily, the mop moves downwards, the foaming cotton is in contact with the squeezing part and moves downwards, the squeezing part is driven by friction force to rotate inwards around the axis of the squeezing part, the squeezing part rotating inwards generates force for enabling the foaming cotton to be squeezed into the squeezing channel more easily, and the squeezing part rotates inwards.

Further improved, the device also comprises an elastic structure which enables the extrusion component to return. Wherein elastic construction can adopt the torsional spring or other modes, and the setting of reset structure enables the extrusion part and kick-backs, and crowded water is accomplished the back, no longer exerts down force to the mop pole, and the elasticity of extrusion part resets and more does benefit to the mop head and breaks away from the extrusion passageway.

The two extrusion parts can rotate in a certain angle range around the axes of the two extrusion parts, the extrusion parts are extrusion rollers with semicircular or fan-shaped or triangular or prismatic cross sections, an elastic structure for keeping the extrusion rollers in an initial state is arranged in the cleaning barrel, and extrusion surfaces, extruded by the foaming cotton, in the extrusion parts are arranged oppositely to form the extrusion channels in the initial state of the extrusion rollers.

Further improved, a limiting structure for limiting the downward movement of the foam cotton to the limit position is arranged on the mop or the cleaning bucket, and when the foam cotton descends to the limit position, the volume of the foam cotton in the extrusion channel above the connecting line of the rotating axes of the two extrusion parts is larger than that of the foam cotton below the connecting line of the rotating axes of the two extrusion parts. Because the foam cotton is large in volume and large in resilience, the upward elasticity of the foam cotton is larger than the downward elasticity, and the upward elasticity difference exists, so that after the foam cotton moves downwards to the extreme position to finish water squeezing, and when downward pressure is not applied to the mop rod any more, the upward elasticity difference can enable the foam cotton to rebound upwards and drive the squeezing component to rotate, and the mop head can be separated from the squeezing channel more favorably.

As a working mode of the limiting part, the limiting structure is a limiting part arranged on the mop, and the limiting part can block the cleaning barrel or the extrusion part to realize limiting. The blocking position between the cleaning barrel and the cleaning barrel can be a blocking position of the top edge of the pre-cleaning barrel or a blocking position of a certain component arranged on the cleaning barrel. The barrier with the pressing member may be a barrier with a surface of the pressing member.

Specifically, the limiting member is a side edge of the mounting member extending in the longitudinal direction, and a distance between the two side edges is greater than a minimum distance formed between the two pressing members. Because the installation component is the part that mop itself has, the installation component can be mounting panel or installation clip, and it has stronger intensity, is fit for as keeping off joining in marriage the part, and installation component itself constitutes the locating part, need not additionally to set up the locating part, and the interval between the both sides portion edge is the width of installation component.

Of course, the limiting part is also a stop block arranged on the mounting part or the mop rod, the mop rod is pressed downwards, and the stop block is abutted with the extrusion part or the cleaning barrel to form a stopping limiting position.

As another working mode of the limiting member, the limiting structure is a limiting member disposed in the cleaning barrel for blocking the bottom of the foam cotton.

In order to ensure that the cleaning and wringing operations of the cleaning barrel are not interfered with each other, the cleaning barrel is internally divided into two wringing areas and a cleaning area which are independent from each other, and the wringing structure is arranged in the wringing areas. In order to clean the foam cotton more cleanly. The bottom of the cleaning area is provided with a cleaning structure for cleaning the foaming cotton.

Compared with the prior art, the invention has the advantages that: when squeezing water, the length direction of the extrusion component and the length direction of the foam cotton are both horizontal, in the process of pressing the mop rod downwards, the foam cotton drives the extrusion component to rotate and roll, the extrusion roller firstly contacts and extrudes with the first lower extrusion position and the second lower extrusion position and gradually transits to the first upper extrusion position and the second upper extrusion position to contact and extrude. The squeezing device is completely different from the traditional downward squeezing mode, the whole squeezing stroke is ensured to be close to the size of the collodion in the thickness direction, the squeezing stroke is short, rapid squeezing can be realized, the water squeezing operation is simple, the time spent is short, only one rapid pressing action is needed, and the user experience is good; compared with the traditional foam cotton cleaning tool, the cleaning bucket can be made to be short, and the cost is reduced.
