Description

Technical Field

[0001] The invention relates to a cleaning tool, in particular to a cleaning tool suitable for cleaning and drying a foam mop, wherein the foam is a wiping material made by a foaming molding process, and can be a collodion, a sponge, a wiping material made of a synthetic material containing foam, or the like. Background Art

[0002] The traditional collodion mop includes a mop rod, a mop head and a water squeezing mechanism. The water squeezing device in the collodion mop is a transmission structure. The water squeezing device includes a handle, a pull rod, a clamp seat (squeezing frame), a collodion clamp and a water squeezing rod. The clamp seat is roughly U-shaped. The collodion head is clamped by the collodion clamp. The collodion clamp is fixed to the bottom end of the pull rod. The top of the pull rod is connected to the movable pin in the middle of the handle. The rear end of the handle is pinned to the mop rod. The two ends of the water squeezing rod are pinned to the lower end of the clamp seat. When squeezing water, the handle is pulled to drive the collodion head to move upward horizontally through the pull rod, and the water squeezing rod squeezes water from the upper part to the lower part in the thickness direction of the collodion. The mop rod of this mop has many parts attached to it, and the structure is complicated, the weight is heavy, and the operation is laborious.

[0003] Someone invented a cleaning bucket specifically for collodion mops, such as the Chinese invention patent application with application number CN201710920255.3, "A cleaning bucket and collodion mop for cleaning collodion mops", and the Chinese invention patent application with application number CN201811267670.4, "A collodion mop squeeze bucket", etc., all disclose similar patents. A water squeezing device is provided on the barrel body, and the squeezing component in the water squeezing device is along the length direction of the foam head and only squeezes the bottom surface of the foam head. The squeezing stroke is long (greater than the length of the mop head), which is time-consuming, and the height of the cleaning bucket must be increased, which increases the cost. When squeezing water, the mop head needs to be rotated to be basically parallel to the mop rod, which is inconvenient to operate.

[0004] Therefore, how to design a cleaning tool for foam mops that is compact and reasonable in structure, low in cost, and can be squeezed dry quickly is a problem that technicians in this field need to solve. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a cleaning tool based on a foam mop with a new water squeezing method, a simple and reasonable structure, low cost and the ability to squeeze out water quickly, in response to the above-mentioned existing technical status. The cleaning bucket used in the cleaning tool can be made low, and the overall structure is compact, which is easy to store and reduces costs.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a foam mop cleaning tool, comprising a cleaning bucket and a mop, the mop comprising a mop head connected to the lower end of the mop rod, the mop head comprising a mounting component and foam arranged at the bottom of the mounting component, the cleaning bucket is equipped with a water squeezing structure for squeezing the foam; the characteristic is that: the water squeezing structure comprises two squeezing components spaced apart from each other, a squeezing channel can be formed between the two squeezing components when squeezing water, and the minimum spacing of the squeezing channel is less than the width of the foam; the foam has a length extending in the direction of the length. The first extruded surface and the second extruded surface are respectively located on the left and right sides of the central axis of the foam, the first extruded surface has a first lower extruded position and a first upper extruded position, and the second extruded surface has a second lower extruded position and a second upper extruded position; when squeezing water, the length direction of the extruding component is horizontal to the length direction of the foam, and in the process of pressing down the mop rod, the extruding component first contacts and squeezes the first lower extruded position and the second lower extruded position, and gradually transitions to contact and squeeze the first upper extruded position and the second upper extruded position.

[0007] As an improvement, at least one of the extrusion components can rotate around its own axis, and during the process of pressing down the mop rod, the foam drives the extrusion component to rotate. The rotation of the extrusion component refers to rotation around a rotation axis within a certain angle range, and the certain angle range can be 360 ​​degrees, or it can be 180 degrees, 90 degrees, or other rotations less than 360 degrees (similar to swinging). When the mop is moved downward, the foam contacts the extrusion component and moves downward. The extrusion component is driven by friction to rotate inward around its own axis, and the inwardly rotating extrusion component generates a force that pulls the foam to the lower part of the extrusion channel, thereby making it easier for the foam to squeeze into the extrusion channel. Of course, one of the extrusion components can be fixed and cannot rotate around its own axis, and the other extrusion component can rotate around its own axis.

[0008] As a further improvement, at least one first extruded surface between the first lower extruded position and the first upper extruded position expands outward from bottom to top. Preferably, the extrusion is gradually expanded outward. In this way, during the squeezing process, the foam cotton forms at least a small and large cross-sectional structure from bottom to top, ensuring that the foam cotton is more easily squeezed into the squeezing channel. At the same time, the foam cotton is squeezed more fully from bottom to top, which also makes the squeezing effect better.

[0009] Of course, it is better if at least one section of the second extruded surface between the second lower extruded position and the second upper extruded position expands outward from bottom to top. Preferably, it expands outward gradually.

[0010] Preferably, both of the two extrusion components can rotate around their own axes, and the extrusion components are extrusion rollers with circular cross-sections. Because the extrusion rollers are circular rollers, no matter which position the extrusion rollers rotate to, the contact surface with the foam is always an arc surface, and the extrusion contact between the extrusion component and the foam is an arc surface contact, so that the extrusion component is not easy to damage the foam during the water squeezing process, and there is no requirement for the assembly direction, which is convenient for assembly and does not require an additional reset structure. In addition, the surface where the extrusion component contacts the foam is an arc surface, so that the extrusion channel has a large upper and small lower structure, which is convenient for water squeezing. The rotating extrusion component can make the foam easier to squeeze into the extrusion channel, and the mop is moved down, and the foam contacts and moves down with the extrusion component. The extrusion component is driven by friction to rotate inward around its own axis, and the inward rotating extrusion component generates a force that brings the foam to the lower part of the extrusion channel, thereby making it easier for the foam to squeeze into the extrusion channel.

[0011] A further improvement includes an elastic structure for rotating and resetting the squeezing component. The elastic structure can be a torsion spring or other means. The setting of the resetting structure can make the squeezing component rebound. After squeezing the water, no downward pressure is applied to the mop rod. The elastic resetting of the squeezing component is more conducive to the mop head to escape from the squeezing channel.

[0012] Both of the extrusion components can rotate around their own axes within a certain angle range. The extrusion components are extrusion rollers with semicircular, fan-shaped, triangular or prismatic cross-sections, and an elastic structure is provided in the cleaning barrel to keep the extrusion rollers in an initial state. When the extrusion rollers are in the initial state, the extrusion surfaces in the extrusion components that form extrusion with the foam cotton are arranged opposite to each other to form the extrusion channel.

[0013] As a further improvement, a limit structure for limiting the downward movement of the foam is provided on the mop or in the cleaning bucket. When the foam moves downward to the limit position, the volume of the foam in the extrusion channel above the line connecting the rotation axes of the two extrusion components is greater than the volume of the foam below the line connecting the rotation axes of the two extrusion components. Because the part with a larger volume of foam has a larger rebound force, the upward elastic force of the foam is greater than the downward elastic force at this time, and there is an upward elastic force difference. Therefore, after the foam moves downward to the limit position and squeezes out water, when the downward pressure is no longer applied to the mop rod, the upward elastic force difference will rebound the foam upward and drive the extrusion component to rotate, thereby making it easier for the mop head to escape from the extrusion channel.

[0014] As a working mode of the limiter, the above-mentioned limiter structure is a limiter provided on the mop, and the limiter can block with the cleaning bucket or the extrusion component to achieve the limit. The blockage between the cleaning bucket can be the top edge of the pre-cleaning bucket for blocking and limiting, or a certain component installed on the cleaning bucket for blocking and limiting. The blockage between the extrusion component can be the blockage between the surface of the extrusion component.

[0015] Specifically, the above-mentioned limiting member is the side edge of the mounting component extending along the length direction, and the distance between the two side edges is greater than the minimum distance formed between the two extrusion components. Since the mounting component is a component of the mop itself, the mounting component can be a mounting plate or a mounting clip, which has strong strength and is suitable as a stopper component. The mounting component itself constitutes the limiting member, and there is no need to set an additional limiting member. The distance between the two side edges is the width of the mounting component.

[0016] Of course, the above-mentioned limiting member can also be a stopper provided on the mounting component or the mop rod. When the mop rod is pressed down, the stopper collides with the extruding component or the cleaning bucket to form a blocking limit.

[0017] As another working mode of the limiting member, the above-mentioned limiting structure is a limiting member arranged in the cleaning barrel to block the bottom of the foam.

[0018] In order to prevent the cleaning and squeezing operations of the cleaning bucket from interfering with each other, the cleaning bucket is divided into two independent squeezing areas and a cleaning area, and the squeezing structure is arranged in the squeezing area. In order to clean the foam cotton more thoroughly, a cleaning structure for cleaning the foam cotton is arranged at the bottom of the cleaning area.

[0019] Compared with the prior art, the advantages of the present invention are: when squeezing water, the length direction of the squeezing component and the length direction of the foam are both horizontal, and in the process of pressing down the mop rod, the foam drives the squeezing component to rotate and roll, and the squeezing roller first contacts and squeezes the first lower squeezing position and the second lower squeezing position, and gradually transitions to contact and squeeze with the first upper squeezing position and the second upper squeezing position. It is completely different from the traditional top-down squeezing method, ensuring that the entire squeezing stroke is close to the size in the thickness direction of the rubber cotton, the squeezing stroke is short, and fast squeezing can be achieved, and the squeezing operation is simple and takes a short time, and only a simple quick downward pressing action is required, and the user experience is good; compared with traditional foam cleaning tools, the cleaning bucket can also be made low to reduce costs.

[0034] The present invention is further described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 3 Shown is a preferred embodiment of the present invention.

[0036] A cleaning tool includes a cleaning bucket 1 and a mop, wherein the mop includes a mop head 3 connected to the lower end of a mop rod 2, wherein the mop head 3 includes a mounting component 31 and a foam 32 disposed at the bottom of the mounting component 31, wherein the mounting component 31 is a long strip mounting plate. The cleaning bucket 1 is provided with a water squeezing structure for squeezing the foam 32, wherein the foam has a certain thickness and strong water absorption.

[0037] The squeezing structure includes two squeezing components 5 spaced apart from each other. When squeezing water, a squeezing channel P can be formed between the two squeezing components 5. The minimum spacing X of the squeezing channel P is smaller than the width D of the foam 32. The width of the foam 32 refers to the maximum width dimension on the cross section of the foam 32. Figure 1 As for whether the squeezing channel P of the aforementioned technical effect is formed when water is not squeezed, it is not important, it may be formed or not, if the relative positions of the two squeezing parts 5 do not change, then the squeezing channel exists from beginning to end, if the two squeezing parts 5 tilt, slide or swing up and down relative to the cleaning bucket, then the squeezing channel may not be formed when water is not squeezed, but at least the squeezing channel will be formed when water is squeezed.

[0038] The foam 32 has a first extruded surface 3a and a second extruded surface 3b extending along the length direction. The first extruded surface 3a and the second extruded surface 3b are respectively located on the left and right sides of the central axis Y of the foam 32. The central axis Y is the axis along the thickness direction of the foam 32. The first extruded surface 3a has a first lower extruded position 3a1 and a first upper extruded position 3a2. The second extruded surface 3b has a second lower extruded position 3b1 and a second upper extruded position 3b2.

[0039] At least one first extruded surface 3a between the first lower extruded position 3a1 and the first upper extruded position 3a2 extends outward from bottom to top. At least one second extruded surface 3b between the second lower extruded position 3b1 and the second upper extruded position 3b2 extends outward from bottom to top.

[0040] The first lower squeezed position 3a1 and the second lower squeezed position 3b1 gradually expand outwards from bottom to top, and the first upper squeezed position 3a2 and the second upper squeezed position 3b2 gradually shrink inwards from bottom to top.

[0041] When squeezing water, the length direction L of the squeezing component 5 and the length direction L of the foam 32 are both horizontal. In the process of pressing down the mop rod 2, the foam 32 drives the squeezing component 5 to rotate. The squeezing component 5 first contacts and squeezes the first lower squeezed position 3a1 and the second lower squeezed position 3b1, and gradually transitions to contact and squeeze the first upper squeezed position 3a2 and the second upper squeezed position 3b2.

[0042] In this embodiment, the two extrusion components 5 can both rotate 360 ​​degrees around their own axes. The extrusion components 5 are extrusion rollers with a circular cross section, so that the surface of the extrusion components 5 in contact with the foam 32 is an arc surface. In this embodiment, the relative position relationship of the rotation axes of the two extrusion components 5 will not change. Of course, an elastic structure can also be provided to enable the extrusion components 5 to rotate and reset. The elastic structure can be a torsion spring, which is not shown in the drawings.

[0043] A limiting structure is provided on the mop or in the cleaning bucket 1 to limit the downward movement of the foam 32 to the extreme position. When the foam 32 moves downward to the extreme position, the volume of the foam 32 in the extrusion channel P above the rotation axis line Z of the two extrusion components 5 is greater than the volume of the foam 32 below the rotation axis line Z of the two extrusion components 5.

[0044] The limiting member 4 in this embodiment is a side edge of the mounting component 31 extending along the length direction L, and the distance S between the two side edges is greater than the minimum distance X formed between the two extrusion components 5 .

[0045] The cleaning bucket 1 in this embodiment is divided into a squeeze-drying area Q1 and a cleaning area Q2 which are independent of each other, and the squeezing structure is arranged in the squeeze-drying area Q1. A cleaning structure 6 for cleaning the foam 32 is arranged at the bottom of the cleaning area Q2. Of course, there can be only one area inside the cleaning bucket, which has both functions or only has the squeezing function.

[0046] In this embodiment, the up-down direction refers to the length direction of the mop rod 1 when preparing to squeeze water or squeezing water, that is, the vertical direction; the horizontal direction refers to the direction parallel or substantially parallel to the ground or the plane where the opening of the cleaning bucket is located (see Figure 1 , when preparing to squeeze water, both L directions are horizontal).

[0047] The working process and principle of the first embodiment of the cleaning tool are as follows:

[0048] When squeezing water, the mop head 3 still maintains a basically vertical state with the mop rod 2, that is, a normal cleaning working state, and the bottom of the foam 32 is placed on the squeezing component 5. The length direction L of the squeezing component 5 and the length direction L of the foam 32 are both horizontal. The mop rod 2 is pressed down to drive the mop head 3 to move downward, and the foam 32 is gradually squeezed into the squeezing channel P formed between the two squeezing components 5 in the length direction L. Because the squeezing component 5 is an squeezing roller with a circular cross-section, the foam 32 contacts the squeezing component 5 and moves downward. The squeezing component 5 rotates inward around its own axis driven by friction, and the inwardly rotating squeezing component 5 generates a force to bring the foam 32 to the lower part of the squeezing channel P, thereby making it easier for the foam 32 to squeeze into the squeezing channel P, and the left and right sides of the foam 32 are squeezed to achieve water squeezing.

[0049] The maximum distance that the mop head 3 moves downward can be effectively controlled by the limiter. When the mop head 3 moves downward to the side edge of the mounting component 31 on it and contacts the squeezing component 5, the mounting component 31 is blocked from moving downward further, ensuring that the entire squeezing stroke is close to the size of the foam 32 in the thickness direction. The squeezing stroke is short, and rapid squeezing can be achieved. Moreover, the squeezing operation is simple and takes a short time. Only a simple quick downward pressing action is required, and the user experience is good. Because the squeezing stroke is greatly shortened compared with traditional foam cleaning tools, the cleaning bucket 1 can be made low, reducing costs. Because the large volume of the foam 32 has a large rebound force, the upward elastic force of the foam 32 is greater than the downward elastic force at this time, and there is an upward elastic force difference. Therefore, after the foam 32 moves downward to the limit position to complete squeezing, when the downward pressure is no longer applied to the mop rod 2, the upward elastic force difference will rebound the foam 32 upward and drive the squeezing component 5 to rotate, thereby making it more conducive for the mop head to escape from the squeezing channel P.

[0050] like Figures 4 to 7 FIG. 2 is a second embodiment of the present invention.

[0051] The difference between this embodiment and the first embodiment is that the squeezing component 5 is a squeezing roller with a semicircular, fan-shaped, triangular or prismatic cross section, and both squeezing components 5 can rotate around their own axes within a certain angle range. Of course, one of the two squeezing components 5 can be fixed and the other can rotate around its own axis. An elastic member is provided in the cleaning barrel 1 to keep the squeezing component 5 that can rotate around its own axis in the initial state. The elastic member is not shown in the drawings and can be a torsion spring. In the initial state of the squeezing roller, the squeezing surface of the squeezing component 5 that forms the squeezing with the foam 32 is arranged opposite to each other to form the squeezing channel P.

[0052] like Figures 8-9 FIG. 1 is a third embodiment of the present invention.

[0053] The difference between this embodiment and the first embodiment is that the limiting member 4 is a stopper provided on the mounting member 31, which presses down the mop rod 2, and the stopper abuts against the extruding member 5 or the cleaning bucket 1 to form a blocking limit.

[0054] like Figure 8 As shown, the limiting member 4 on the mounting component 31 and the protrusion 11 on the side wall of the cleaning bucket 1 are blocked and limited.

[0057] The difference between this embodiment and the first embodiment is that the limiting member 4 is a stopper provided on the mop rod 2, which presses the mop rod 2 downward and the stopper abuts against the extruding member 5 or the cleaning bucket 1 to form a blocking limit.

[0058] like Fig.10 As shown, the limiting member 4 on the joint of the mop rod 2 and the extruding member 5 are blocking and limiting each other.

[0059] like Fig.11 As shown, the bottom surface of the foam 32 and the protrusion 11 on the side wall of the cleaning barrel 1 are blocked and limited.

[0060] like Fig.12 As shown, the limiting member 4 on the mop rod 2 and the extruding member 5 are blocking and limiting each other.

[0061] like Fig.13 As shown, the limiting member 4 on the mop rod 2 is limited by the frame 12 fixed on the cleaning bucket 1.

[0062] like Fig.14 FIG. 1 is a third embodiment of the present invention.

[0063] The difference between this embodiment and the first embodiment is that the limiting structure is a limiting member 4 provided in the cleaning barrel 1 for blocking the bottom of the foam 32 .
