Technical Field

The invention relates to a wringing device for bilaterally squeezing foam cotton in a mop head, which can be used on a cleaning tool comprising a cleaning barrel and can also be used on a self-wringing foam cotton mop, wherein the foam cotton can be a collodion cotton head, a sponge head or the like. The invention also relates to a cleaning tool with the water squeezing device and a cleaning barrel, and a self-water-squeezing foam cotton mop with the water squeezing device.

Background

The invention is specially designed for a cleaning tool of a foam cotton mop or a self-squeezing foam cotton mop, and is provided with a water squeezing device, wherein the cleaning tool comprises a cleaning barrel and a mop head which is rotatably connected to the lower end of a mop rod and is provided with foam cotton, and the water squeezing device is arranged on the cleaning barrel. The self-squeezing foam cotton mop is characterized in that the squeezing device is arranged on the mop rod and can slide up and down along the mop rod. The squeezing device has similar structure, the squeezing component in the squeezing device squeezes the foam cotton on the mop head which moves up and down through the squeezing device, and the foam cotton has larger size in the thickness direction due to the characteristics of the foam cotton material, so that two squeezing modes are adopted for the squeezing structure of the foam cotton mop.

A first water squeezing mode: the squeezing component only squeezes the bottom surface of the foam cotton, and the Chinese patent application with the application number of CN201811267670.4 discloses a first water squeezing mode, namely a collodion mop squeezing barrel, and the Chinese patent application with the application number of CN201710920255.3 discloses a cleaning barrel and a collodion mop for cleaning the collodion mop.

A second water squeezing mode: the two squeezing parts can simultaneously squeeze the left and right sides of the foam cotton, and a second water squeezing mode is disclosed in the Chinese utility model patent with the patent number ZL201821624855.1, which is applied by the applicant.

The two water squeezing modes have the characteristics respectively, and compared with the first water squeezing mode, the second water squeezing mode has better water squeezing effect and relatively labor-saving water squeezing operation. However, the cleaning tool of the second prior art has the following commonalities: 1. the foaming cotton is fixed on the mounting plate in a bonding mode, the mounting plate is connected to the mop plate, or the foaming cotton is bonded on the mop plate; 2. the squeezing surfaces of the two squeezing parts, which are contacted with the foam cotton, are arranged in parallel at intervals, namely the width of a squeezing channel between the two squeezing parts along the axial direction of the squeezing parts (basically deviated to the thickness direction of the foam cotton) is basically consistent, and the bottom surface of the foam cotton has a certain radian. When the mop head passes through the extrusion opening of the extrusion device, the extrusion force of the extrusion part on the left side and the right side of the foam cotton along the thickness direction is basically the same, or the extrusion force of the extrusion part on the left side and the right side of the foam cotton close to the mop plate is slightly larger than that in the direction far away from the mop plate, water is extruded to be dry, the extrusion force needs to be larger, and the problem that the bonding surface of the foam cotton is easily torn to cause product damage is caused.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a wringing device for double-side squeezing of foam cotton in a mop head, aiming at the current situation of the prior art, wherein the wringing device is not easy to tear the bonding surface of the foam cotton in the cleaning and wringing operation processes.

The technical scheme adopted by the invention for solving the technical problems is as follows: a technical device for double-side extrusion comprises a water extrusion frame with extrusion ports, wherein two groups of extrusion components are arranged in the extrusion ports, are oppositely arranged at left and right intervals and form an extrusion channel between the two extrusion components; the method is characterized in that: the extrusion width of the inner end of the extrusion channel in the direction close to the mop head is larger than that of the outer end of the extrusion channel in the direction far away from the mop head, and when the foam cotton passes through the extrusion port and is extruded by the extrusion part, the extrusion force of the extrusion part to the two sides of the outer end of the foam cotton is larger than that to the two sides of the inner end of the foam cotton.

Alternatively, the extrusion side wall between the inner end and the outer end of the extrusion channel is a bevel or a cambered surface or a tooth surface.

Preferably, the squeezing member is a squeezing roller rotating around a rotation axis thereof, the rotation axis position of the squeezing roller is unchanged, and the squeezing roller is in a circular truncated cone shape, so that the squeezing width of the squeezing channel at the inner end in the direction close to the mop head is larger than that at the outer end in the direction away from the mop head. The appearance of this squeeze roll is different with traditional cylindric squeeze roll, during the equipment, holds the minor diameter of squeeze roll and is close to the mop head direction and sets up, hold the major diameter of squeeze roll towards keeping away from the mop head direction can, only need reform transform the appearance of squeeze roll for this reason, need not to change the mounted position in the crowded water frame.

The oblique arrangement of the axis of rotation of the press rolls results in the oblique arrangement of the press rolls coaxially mounted on this axis of rotation.

As one installation mode of the squeeze roll, the squeeze roll is sleeved on a pin shaft and can rotate around the axis of the squeeze roll, and the pin shaft is installed on a water squeezing frame to form a rotation axis of the squeeze roll. The installation mode is favorable for installation, and a protruding pivot shaft can be arranged at two ends of the squeezing roller and is installed in the installation hole of the squeezing frame through the pivot shaft.

As another structure of the extrusion component, the extrusion component is a fixed block fixed on the water extrusion frame.

In order to prevent the fixed block from scratching the foaming cotton, the extrusion side wall extruded with the foaming cotton in the fixed block is a cambered surface.

The second technical problem to be solved by the present invention is to provide a cleaning tool for a foam cotton mop with double-side squeezing, which is not easy to tear the bonding surface of the foam cotton during the cleaning and squeezing operation, and can complete the cleaning operation and the squeezing operation in one barrel space.

The technical scheme adopted by the invention for solving the second technical problem is as follows: a cleaning tool comprises a cleaning barrel and a mop head which is rotatably connected to the lower end of a mop rod, wherein foaming cotton is directly or indirectly bonded to the bottom surface of the mop head, and the cleaning tool is characterized in that: the water squeezing device is further included, and the water squeezing frame is arranged on the cleaning barrel.

The mop rod and the mop head of the traditional flat plate mop are in universal connection (the mop rod swings back and forth and left and right relative to the mop head), and due to the fact that the thickness of the foaming cotton is thick and the gravity center of the foaming cotton is high, when a user applies force to mop the floor along the width direction (front and back direction) of the foaming cotton, the mop head is prone to rollover, the comfort of mop operation is seriously affected, and in order to avoid the situation, the technical bias is overcome, and the mop rod is designed to swing left and right only relative to the mop head and along the length direction of the mop head. Therefore, even if a user applies force to mop the floor along the width direction of the foam cotton, the folded mop head is not easy to turn over, and the floor mopping operation is more comfortable.

The improved mop is characterized in that a rib groove inserting and matching guide structure is arranged between the water squeezing frame and the mop head, and the mop head moves up and down in the penetrating opening along a preset track under the action of the rib groove inserting and matching guide structure so as to prevent the mop head from overturning or deviating.

Insert through muscle groove and join in marriage guide structure guide mop head and reciprocate in the extrusion mouth along predetermineeing the orbit, take place the skew and make the mop head card go into between two extrusion parts when can enough avoiding the foaming cotton to contact with extrusion parts, when reducing the mop head and wearing mouthful the resistance that removes, it is more effective to make the mop head contact with extrusion parts, crowded water process is more laborsaving, crowded water effect is better, can also avoid taking place to overturn when mop head and extrusion parts contact and make the mop head take place to interfere with crowded water frame, guarantee crowded water normal clear.

As a specific design of the rib groove inserting and matching guide structure, the rib groove inserting and matching guide structure comprises a guide groove and a convex rib, and the convex rib is inserted into the guide groove and slides in the guide groove in the process that the mop head passes through the extrusion opening; one of the guide groove and the convex rib is arranged on the water squeezing frame, and the other of the guide groove and the convex rib is arranged on the mop head.

The third technical problem to be solved by the present invention is to provide a double-side squeezing self-squeezing foam cotton mop, which is not easy to tear the bonding surface of the foam cotton during the cleaning and squeezing operation.

The technical scheme adopted by the invention for solving the third technical problem is as follows: the utility model provides a from crowded cotton mop of water foam, includes the mop pole and rotates the mop head of connecting at mop pole lower extreme, the bottom surface of mop head is directly or indirectly bonded there is the foam, its characterized in that: the mop water squeezing device also comprises the water squeezing frame which is arranged on the mop rod and can slide up and down along the mop rod.

Compared with the prior art, the invention has the advantages that: the left and right sides interval of two sets of extrusion parts is to establishing, and every group extrusion part (like the squeeze roll) can be one or more, carries out the crowded water to the left and right sides of foam cotton through the length direction of following the foam cotton to the extrusion part who establishes, and two sides are extruded simultaneously and are compared in unilateral extrusion, and extrusion distance is littleer, also can reduce crowded water resistance.
