Description

Technical Field

[0001] The invention relates to a foam cotton head mop, in particular to a squeezing rack for a foam cotton head mop for squeezing water from a foam cotton head. The foam cotton head may be a rubber cotton head, a sponge head or the like. Background Art

[0002] The structures of the rubber cotton mops currently on the market are roughly the same, including a mop rod, a mop head and a water squeezing mechanism. The water squeezing device in the rubber cotton mop is a transmission structure. The water squeezing device includes a handle, a pull rod, a clamp seat (squeezing frame), a rubber cotton clamp and a water squeezing rod. The clamp seat is roughly U-shaped, and the rubber cotton head is clamped by the rubber cotton clamp. The rubber cotton 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 water squeezing rod is oblate, and its two ends are pinned to the lower end of the clamp seat. During the water squeezing operation, the handle is pulled to drive the rubber cotton head to move upward horizontally through the pull rod. The rubber cotton head passes between the squeezing rods of the squeezing frame. Because the squeezing rod has an elastic force that maintains a clamping tendency, the rubber cotton head passing through the squeezing rod will be clamped by the squeezing rod to achieve water squeezing.

[0003] At present, a more advanced self-squeezing foam mop has appeared on the market, which includes a mop rod and a foam head. The foam head is movably connected to the lower end of the mop rod. The mop rod is provided with a squeezing device that can slide along the mop rod. The foam head can be rotated so that its length direction is basically parallel to the mop rod and aligned with the squeezing device. When squeezing water, the squeezing device slides along the length direction of the foam head and squeezes the left and right sides and / or the bottom surface of the foam head to achieve squeezing water. When mopping the floor, the foam head is completely separated from the squeezing device.

[0004] Because foam cotton has the characteristics of large thickness and strong water absorption compared with traditional mops, the extrusion hole formed by the extrusion component in the hole is small, which is conducive to squeezing water from the foam cotton. The disadvantage is that the foam cotton is not easy to pass through the extrusion hole. The extrusion hole height will make it easy for the foam cotton to pass through the extrusion hole, and the disadvantage is that the water squeezing effect is poor.

[0005] In summary, the existing collodion mop can be further improved. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a self-squeezing foam mop which is conducive to the foam mop head entering the squeezing rack and ensures the squeezing effect in view of the above-mentioned existing technical status.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a self-squeezing foam mop, comprising a mop rod, a mop head with foam cotton rotatably connected to the lower end of the mop rod, the mop rod is provided with a squeezing frame that can slide along the mop rod, the squeezing frame has a through hole, and the through hole is provided with a squeezing structure for squeezing the foam cotton passing through the through hole, when squeezing water, the mop head is rotated to align with the through hole, and then passes through the through hole; the characteristic is that: the squeezing structure includes a swing frame and an elastic member, the middle part of the swing frame is rotatably connected to the through hole, and the swing frame is provided with a squeezing structure for squeezing the foam cotton An extrusion component for extrusion, the elastic component causes the swing frame to swing to the first position, thereby forming an extrusion channel with a cross-section that gradually decreases from bottom to top in the through opening, and the upper part of the extrusion channel has the extrusion component; a guide component is provided on the mop rod, and the guide component has a shelf surface. The water squeezing frame slides relative to the mop rod to make the swing frame rest on or detach from the shelf surface. When the swing frame rests on the shelf surface, the swing frame overcomes the elastic force of the elastic component and swings to the second position. When the swing frame detaches from the shelf surface, the swing frame swings to the first position under the action of the elastic component.

[0008] As a further improvement, the guide component also has a guide slope, which facilitates the guide component to cut into the small-caliber of the extrusion channel and gradually slide upward along the guide slope toward the shelf surface.

[0009] As a method, when the squeezing frame moves downward relative to the mop rod, the swing frame moves away from the guide component; when the squeezing frame moves upward relative to the mop rod, the swing frame moves toward the guide component. Of course, the reverse arrangement is also possible.

[0010] If the mop head is upwardly separated from the hole, the swing frame is in the first position, which makes it inconvenient for the mop head to exit downward from the hole. Therefore, the squeezing frame is provided with a guide groove for guiding the guide component. After the guide component is located at the uppermost end of the guide groove and is limited, the lower end of the mop head is still located in the hole, which makes it convenient for the mop head to exit downward from the hole.

[0011] Preferably, the squeezing component is a first squeezing roller rotatably mounted on the upper end of the swing frame, and a second squeezing roller mounted on the lower end of the swing frame; the squeezing roller acts on the bottom surface of the foam head (that is, the bottom surface of the foam head in use) to squeeze water, and because the contact between the rolling squeezing roller and the foam head is rolling contact, the foam head can be driven through the squeezing frame more easily, which is more labor-saving and will not damage the foam.

[0012] The extrusion channel can be realized by the following swinging frame swinging method. When the swing frame is in the first position, the second water squeezing roller swings in the direction away from the mop rod, thereby forming the lower end of the extrusion channel. At the same time, the first water squeezing roller at the upper end of the swing frame swings in the direction close to the mop rod, thereby forming the upper end of the extrusion channel; when the swing frame is in the second position, the first water squeezing roller is placed on the placement surface.

[0013] Compared with the prior art, the present invention has the following advantages: when squeezing water, the squeezing frame moves downward relative to the mop rod, so that the swing frame is separated from the shelf surface on the guide component, and the swing frame swings to the first position under the action of the elastic member, thereby forming an extrusion channel with a cross-section that gradually decreases from bottom to top in the through-hole. Since the extrusion channel is a channel that is larger at the bottom and smaller at the top, it is convenient for the foam cotton head to enter the through-hole in advance, and pre-extrude the foam cotton head through the squeezing channel, and then the foam cotton head is strongly squeezed by the squeezing component located at the upper part of the squeezing channel, which will reduce the resistance of the foam cotton head passing through the squeezing component, and the squeezing operation will be further labor-saving. After squeezing water is completed, the squeezing frame moves upward relative to the mop rod, and the swing frame climbs to the shelf surface and is in the second position. The swing frame in the second position will not form an extrusion channel that is larger at the bottom and smaller at the top. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 6 Shown is a preferred embodiment of the present invention.

[0022] A self-squeezing foam mop comprises a mop rod 1, a mop head 2 rotatably connected to the lower end of the mop rod 1 and having foam 21, the mop rod 1 is provided with a squeezing frame 3 that can slide along the mop rod, the squeezing frame 3 has a through hole X, and the through hole X is provided with a squeezing structure for squeezing the foam 21 passing through the through hole X. When squeezing water, the mop head 2 rotates to align with the through hole X and then passes through the through hole X.

[0023] The extrusion structure includes a swing frame 5 and an elastic member 4. The middle part of the swing frame 5 is rotatably connected in the through hole X. The swing frame 5 is provided with an extrusion component 6 for extruding the foam 21. The elastic member 4 causes the swing frame 5 to swing to a first position trend, thereby forming an extrusion channel P with a cross-section that gradually decreases from bottom to top in the through hole X. The upper part of the extrusion channel P is provided with the extrusion component 6. The mop rod 1 is provided with a guide component 8, and the guide component 8 has a shelf surface 81. The water squeezing frame can slide relative to the mop rod 1 to make the swing frame 5 rest on or detach from the shelf surface 81. When the swing frame 5 is resting on the shelf surface 81, the swing frame 5 overcomes the elastic force of the elastic member 74 and swings to the second position. When the swing frame 5 is detached from the shelf surface 81, the swing frame 5 swings to the first position under the action of the elastic member 4.

[0024] The guide component 8 further has a guide slope 82 , and the guide slope 82 is located below the placement surface 81 .

[0025] When the water squeezing frame 3 moves downward relative to the mop rod 1 , the swing frame 5 moves away from the guide component 8 ; when the water squeezing frame 3 moves upward relative to the mop rod 1 , the swing frame 5 moves toward the guide component 8 .

[0026] The water squeezing frame 3 is provided with a guide groove 31 for guiding the guide component 8 . After the guide component 8 is located at the uppermost end of the guide groove 31 and is limited, the lower end of the mop head 2 is still located in the through opening X.

[0027] The squeezing component 6 is a first squeezing roller 61 rotatably mounted on the upper end of the swing frame 5, and a second squeezing roller 62 mounted on the lower end of the swing frame 5. When the swing frame is in the first position, the second squeezing roller 62 swings away from the mop rod 1 to form the lower end of the squeezing channel P, and at the same time, the first squeezing roller 61 at the upper end of the swing frame 5 swings toward the mop rod 1 to form the upper end of the squeezing channel P; when the swing frame 5 is in the second position, the first squeezing roller 61 is placed on the placing surface 81.

[0028] The first embodiment is used in the foam mop as follows:

[0029] like Figure 2 , 3As shown, when squeezing water, the mop head 2 is rotated to be substantially parallel to the mop rod 1 in the length direction L and the side of the foam 21 is aligned with the through hole X of the squeezing water frame 3. When squeezing water, the entire squeezing water frame 3 slides up and down along the length direction L of the mop head 2 and squeezes the bottom surface of the foam 21 to squeeze water. When mopping the floor, the foam head 2 is completely separated from the squeezing water frame 3.

[0030] The squeezing frame 3 moves downward relative to the mop rod 1, the swing frame 5 moves away from the guide component 8, the first squeezing roller 61 slides from the resting surface 81 along the guide inclined surface 82 to the lower position of the guide inclined surface 82, and the swing frame is in the first position state, forming an extrusion channel P. Specifically, the second squeezing roller 62 swings away from the mop rod 1 to form the lower end of the squeezing channel P. At the same time, the first squeezing roller 61 at the upper end of the swing frame 5 swings toward the mop rod 1 to form the upper end of the squeezing channel P. The squeezing frame 3 continues to move downward. Since the squeezing channel P is a channel that is larger at the bottom and smaller at the top, it is convenient for the mop head 2 to enter the through hole X in advance, and pre-squeeze the foam 21 through the squeezing channel P. Then, the first squeezing roller 6 strongly squeezes the bottom surface of the foam 21, which will reduce the resistance of the foam 21 passing through the first squeezing roller 61, and the squeezing operation is further labor-saving.

[0031] The up-down direction in this embodiment refers to the length direction along the mop rod 1 .
