As shown in Figure 1, 2, the foamed cotton head mop of the utility model embodiment, including mop rod 10, and be connected to and drag The foamed cotton head 20 of 10 bottom of barre, foamed cotton head 20 are connect by being located at the connecting component 30 at the top of it with crowded frame 1.The hair Foam head 20 can turn to the state substantially parallel with mop rod 10 relative to mop rod 10, keep its bottom surface 21 and mop rod flat It goes and completely outside, the connecting component 30 at the top of foamed cotton head 20 rotates relative to mop rod 10 and close to mop rod 10, and then realize the folding storage of mop；Foamed cotton head 20 can also be expanded to the shape vertical with mop rod 10 relative to mop rod State, and then the operation such as cleaned and mopped floor.

It is connected with squeezing water on the mop rod 10, for extracting foamed cotton head 20, which includes connection In the crowded frame 1 on mop rod 10, the crowded frame 1 can move up and down relative to mop rod 10.

It squeezes frame 1 and is equipped with opening, form channel 11, can pass through when parallel relative to mop rod 10 for foamed cotton head 20, The sectional dimension when size in the channel 11 is not squeezed slightly larger than foamed cotton head, enables foamed cotton head 20 just by this Channel 11, and the surrounding side wall in channel 11 will not generate extruding to foamed cotton head 20.Therefore, the size and foamed cotton in channel 11 First 20 sectional dimension when not being squeezed matches.

Preferably, as shown in Fig. 2, squeezing frame 1 is ring structure, it is preferred that squeezing frame 1 has rectangular circumferential surface, 11, channel In in rectangular circumferential surface.And frame 1 is squeezed close to the side of mop rod 10, that is, squeezes the side that frame 1 is connected with mop rod 10 and leads equipped with one To hole 12, the pilot hole 12 is passed through for mop rod 10, and crowded frame 1 is moved down on pilot hole 12 is on mop rod 10 It is dynamic.This squeezes frame 1 generally in the plane vertical with mop rod 10.Pilot hole 12 is connected to the channel 11.

The other side opposite with mop rod 10 of frame 1, the i.e. side far from mop rod 10 and pilot hole 12 are squeezed, list is connected with A squeeze roll 3, axis 31 and the mop rod 10 of squeeze roll 3 are vertically arranged, and squeeze roll 3 can be rotated around axis 31.Preferably, it is oriented to Hole 12 is located on the face of the side of rectangular circumferential surface, which is located on opposite face parallel with 12 place face of pilot hole, and The squeeze roll 3 is at least partially disposed in the channel 11, so that squeeze roll 3 along mop rod 10 when moving up and down, it is described to squeeze The week of damping roller 3 carries out in face of the bottom surface of foamed cotton head 20 around 31 rotary squeezing of axis.Since the section of squeeze roll 3 is round or ellipse Circle, circumferential surface be annular surface, not only for single roller but also can pivoting, therefore, the bottom surface 21 of foamed cotton head 20 is by water squeezing It is to carry out rotary squeezing in face of the bottom surface 21 of foamed cotton head 20 in the week of squeeze roll 3, what the same point was subject to is when the extruding of roller 3 Extruding force from small to large and from big to small, the i.e. extruding force are in being gradually increased and diminishing variation.And it is because single The circumferential surface of the setting of squeeze roll, squeeze roll is circular ring shape, so foamed cotton head is more when squeeze roll moves up and down with crowded frame 1 It is easily accessible the channel within crowded frame 1, in the prior art in order to enable foamed cotton head and squeeze roll contact squeeze, it will usually send out The both ends corner setting chamfering of foam head is contacted for squeeze roll to be accessed, and the application does not have to the setting inclined-plane and can just make to foam Cotton head can smoothly enter into squeeze in the channel of crowded frame 1 for squeeze roll and be discharged.And production complexity is also reduced, and can be simultaneously Reduce the production cost of foamed cotton head and squeeze roll.

Therefore, when water squeezing 20 stress of foamed cotton head variation, cause water energy is enough uniformly, efficiently to squeeze from foamed cotton head 20 Out, there is preferable water squeezing effect.And the setting of single squeeze roll, so that overall structure is more compact simple, it is easy to process Installation, while guaranteeing water squeezing effect, cost is relatively low.

As shown in figure 9, on the basis of the above-mentioned embodiment using single squeeze roll water squeezing, because of squeeze roll rolling extrusion Foamed cotton head can also be applied while application to foamed cotton head along the extruding force f1 of foamed cotton head thickness direction to foamed cotton head Add the power f2 parallel with its bottom surface 21.Therefore, if squeeze roll is too near to mop rod 10, i.e. squeeze roll extruding foaming cotton head mistake If degree, the power of f2 can be such that foamed cotton head 20 shuts down from connecting component 30, or can pull foamed cotton head to breakage, because This, squeeze roll 3 is unable to the excessive compression foamed cotton head 20.As shown in figure 9, since water squeezing rod 3 is rotary squeezing foamed cotton head 20, And squeeze roll 3 is to move up and down with crowded frame 1 along mop rod 10, and therefore, the circumferential surface of squeeze roll 3 and its axis 31 are along fixed Track movement.

The damage of foamed cotton head 20 in order to prevent, the motion profile of the axis 31 of the squeeze roll 3 should as shown in C line in Fig. 9 Track C is located at the outer side bottom surface of the original depth of foamed cotton head 20, or in the bottom surface of the original depth positioned at foamed cotton head 20 When side, the motion profile C of squeeze roll is h with the distance between bottom surface when foamed cotton head original depth, and the diameter of squeeze roll is D, as shown in figure 9, h < 0.5D or track C are located at when the axis of the squeeze roll is at the inside of the original depth of foamed cotton head When the outer side bottom surface of the original depth of foamed cotton head, h≤0.3D.Preferably, the motion profile C of the axis of the squeeze roll, no matter The inside bottom surface of the original depth of foamed cotton head or outside, the distance of bottom surface when original depth apart from foamed cotton head is all No more than 0.3D, that is, h≤0.3D.If the motion profile of the axis 31 of squeeze roll 3 is located at initial when foamed cotton head is not squeezed When the outer side bottom surface of thickness D1, h takes positive number, at this point, if the motion profile of the axis 31 of squeeze roll 3 be located at foamed cotton head not by When the inside bottom surface of original depth D1 when extruding, h takes negative, then at this time | h |≤0.3D.In this way, rationally setting squeeze roll exists The positional relationship of bottom surface when motion profile and foamed cotton head when extruding foaming cotton head are not squeezed, so that foamed cotton head 20 is not It will receive the power of squeeze roll excessive compression, foamed cotton head 20 is hardly damaged, and squeezing effect can control.

Also, the original depth of foamed cotton head is D1, and foamed cotton head after extruding is as sent out with a thickness of D2, the D2-D1 Foam head be squeezed after amount of compression, which is D/2-h, i.e. D2-D1=(D/2-h), at this point, if squeeze roll 3 When the motion profile of axis 31 is located at the outer side bottom surface of original depth D1 when foamed cotton head is not squeezed, h takes positive number, at this point, such as When the motion profile of the axis 31 of fruit squeeze roll 3 is located at the inside bottom surface of original depth D1 when foamed cotton head is not squeezed, h takes negative Number, foamed cotton head is extruded excessively and damages in order to prevent, and can guarantee the efficiency of water squeezing simultaneously again, and amount of compression 0.6D1 < (D/2-h)<0.9D1。

The foamed cotton head 20 is by the extruding water squeezing of squeeze roll 3, and the original depth before being squeezed is D1, after being squeezed With a thickness of D2, D2/D1 0.1-0.4.Squeeze roll 3 is one, and the diameter of squeeze roll is D, the original depth D1 with foamed cotton head Than for 0.35-2.5.Preferably, the original depth D1 ratio of the diameter D of the squeeze roll and foamed cotton head is 0.4-1, is not only squeezed in this way The enough extruding foaming cotton heads of the size of damping roller, and good appearance, can reduce cost under the premise of guaranteeing extruding efficiency.

Because the thickness of foamed cotton head can according to need selection, preferably 32mm-45mm thickness, so, general water squeezing The diameter of roller is 12mm-70mm, it is preferred that is 15mm-50mm.Such setting so that foamed cotton head thickness and squeeze roll Ratio between diameter is the most reasonable, so that water squeezing is more laborsaving quickly.

Since the size in channel 11 is slightly larger than foamed cotton head 20 in the sectional dimension not under by any extruding, and play extruding Effect is the squeeze roll 3 in the channel, therefore, when foamed cotton head does not have to and hardens for a long time, may can not be successfully from Pass through in channel 11, such case occurs in order to prevent, and it includes the work squeezing frame ontology 13 and connecting with crowded frame ontology 13 that this, which squeezes frame 1, Moving part 4.As shown in Figure 3,4, squeeze roll 3 is connected to crowded frame 1 by movable part 4, and movable part 4 can be moved relative to crowded frame ontology 13 It is dynamic, so that the squeeze roll 3 has the first position far from foamed cotton head 20, and close to the second position of foamed cotton head 20, squeeze For damping roller 3 at first position, squeeze roll 3 does not generate squeezing effect to foamed cotton head 20, and squeeze roll 3 is at the second position, just extremely Small part is located in the channel 11, i.e., at this point, the minimum distance of the squeeze roll 3 from mop rod 10 is less than the foamed cotton head 20 Original depth D1, enables the bottom surface 21 of 3 extruding foaming cotton head 20 of squeeze roll.

Preferably, the first end of the movable part 4 and crowded side of the frame ontology 13 far from mop rod 10 are hinged, so that movable The second end of part 4 can be rotated relative to crowded frame ontology 13 or mobile, second end of the squeeze roll 3 set on movable part 4.

The movable part 4 is rotated around it with the hinged hinged shaft of crowded frame ontology 13, so that the second end of movable part 4 is far from mop When bar 10, squeeze roll 3 is located remotely from the first position of mop rod 10 and foamed cotton head 20, and squeeze roll 3 is far from mop rod 10 at this time With channel 11, squeezing effect will not be generated to foamed cotton head 20, foamed cotton head 20 can pass through the channel 11 of crowded frame 1.

When movable part 4 is rotated around it with the hinged hinged shaft of crowded frame ontology 13, so that the second end of movable part is close to mop rod When 10, squeeze roll 3 is located at close to the second position of mop rod 10 and foamed cotton head 20, at this point, at least partly position of squeeze roll 3 In in channel 11, in turn, squeeze roll 3 is squeezed the bottom surface 21 of foamed cotton head 20, and then reach water squeezing effect.

In order to enable squeeze roll 3 to be locked in the second position, when preventing crowded frame 1 from moving up and down relative to mop rod 10, squeeze Damping roller is removed from the second position and can not play the role of extruding foaming cotton head 20, be additionally provided between the movable part 4 and crowded frame 1 by Movable part 4 is locked in the locking device of the second position.

Preferably, which includes the hinged face 41 far from mop 10, which is equipped with hinged shaft and crowded frame sheet Position of the body 13 far from mop rod 10 is hinged, and hinged face 41 and the hinged hinged shaft of crowded frame ontology 13 are parallel with the axis 31 of squeeze roll 3, Movable part 4 further includes being located at hinged 41 two sides of face, and squeezing the side 42 that two sides extend below frame ontology 13, squeeze roll 3 The both ends of axis 31 are connected to two sides 42, and squeeze roll 3 is moved with movable part 4.The locking device includes setting In the card hole 421 on side 42, and on crowded frame ontology 13 corresponding position fixture block 131, when movable part 4 is around itself and crowded frame When the hinged hinged shaft of ontology 13 turns to its second end close to mop rod 10, i.e., when squeeze roll 3 is located at the second position, fixture block 131 It is stuck in the card hole 421, so that the second end of movable part 4 is connect with crowded frame ontology 13.

Those skilled in the art can also understand that, in addition to movable part 4 mentioned by above-described embodiment and locking device knot Structure can also use the movable part 4 and locking device of other structures, as long as movable part 4 can be moved relative to crowded frame ontology 13, Squeeze roll 3 is switched between above-mentioned first position and the second position, and locking device can be by squeeze roll and activity Part is located in the second position.

As shown in Fig. 5,6,7,8, in the above-mentioned second position, i.e. when being at least partially disposed in channel 11 of squeeze roll 3, squeeze Damping roller 3 can also have certain mobility relative to crowded frame 1, can move close to or far from mop rod 10.And it should When crowded frame 1 is moved up relative to mop rod 10, which is in different states, i.e. the squeeze roll 3 has Close to the first state of mop rod 10, and the second state far from mop rod 1.Such as it squeezes frame 1 and is moved up relative to mop rod 1 When, squeeze roll 3 is in first state, and when crowded frame 1 is moved down relative to mop rod 1, squeeze roll is in the second state；Or it squeezes When frame 1 is moved down relative to mop rod 1, squeeze roll 3 is in first state, as shown in figure 8, squeeze frame 1 relative to mop rod 1 to When upper mobile, squeeze roll is in the second state, as shown in Figure 6.Switching between the two states, so that squeeze roll 3 squeezes hair The amount of compression of foam head is different, and not only water squeezing effect is good, and can prevent collodion from damaging.

The either first state or the second state, crowded frame 1 is moved up and down along mop rod 10 and foamed cotton head 20 is logical When crossing crowded frame 1, squeeze roll 3 squeezes the foamed cotton head 20 always, and the foamed cotton head 20 is after first state is extruded Difference between thickness and the original depth of foamed cotton head 20 is defined as the first amount of compression d1, the second state be extruded after thickness with Difference between the original depth of foamed cotton head 20 is defined as the second amount of compression d2, d1/d2 > 2.Two such difference amount of compression is set It sets, so that squeeze roll is when with crowded frame up and down motion extruding foaming cotton head bottom surface, the dynamics of extruding varies, and in proper order gradually Into, not only squeezing effect more preferably, nor foamed cotton head easy to damage.Because when squeeze roll up and down motion extruding foaming cotton head all It is same amount of compression, amount of compression is excessive, is easily damaged foamed cotton head, and amount of compression is too small, be easy to cause squeezing effect variation efficiency It is lower.

Preferably, the both ends of the axis 31 of the squeeze roll 3 are movably connected on two sides of crowded frame 1, i.e. the squeeze roll 3 31 both ends of axis are movably connected on two sides 42 of movable part 4.It sets on two sides 42 of movable part 4 through the oblique of its side Slot 422, the skewed slot 422 extend from first end to second end, and the first end of skewed slot 422 is close to mop rod 10, and the of skewed slot 422 Two ends are far from mop rod 10, i.e., when the axis 31 of squeeze roll 3 is located at the first end of skewed slot 422, are in first state, squeeze roll 3 Axis 31 when being located at the second end of skewed slot 422, be in the second state.

The skewed slot 422 extends to the direction far from mop rod from top to bottom, i.e., first end is located above, under second end is located at Side.When the axis 31 of squeeze roll 3 is located at top, that is, first end of skewed slot 422, squeeze roll 3 is squeezed closer to the mop rod 10 Damping roller 3 is located at first state, and when the axis 31 of squeeze roll 3 is located at lower section, that is, second end of skewed slot 422, squeeze roll 3 is dragged far from this Barre 10, i.e. squeeze roll 3 are located at the second state.

Therefore, when crowded frame 1 is moved downward relative to mop rod 1, as shown in figure 8, i.e. foamed cotton head 20 passes through from bottom to top When the channel 11, due to the setting of skewed slot 422 and the effect of foamed cotton head 20, foamed cotton head 20 is located at skewed slot 422 upwards First end, at this point, squeeze roll 3 is located at first state.And when squeeze frame 1 moved upwards relative to mop rod, i.e., as shown in fig. 6, When foamed cotton head 20 passes through the channel 11 from the top down, squeeze roll 3 is under the action of foamed cotton head 20 positioned at the of skewed slot 422 Two ends are located at the second state.

Between the axis 31 and crowded frame 1 of the squeeze roll 3, it is also connected with elastic component 5, the elastic component 5 makes the squeeze roll 3 With the trend for being always positioned at first state, that is, have always can preferably extruding foaming cotton head 20 trend.Such as Fig. 3 institute Show, elastic component 5 is spring, and both ends are connected between the second end of skewed slot 422 and the axis 31 of squeeze roll 3.And elastic component 5 So that the axis 31 of squeeze roll 3 has the trend for the first end for being always positioned at skewed slot 422.Lead to when foamed cotton head 20 passes through from the top down When road 11, the axis 31 for the power drive squeeze roll 3 that foamed cotton head 20 moves downward squeezes elastic component 5, so that 3 down fold of squeeze roll 422 second end is mobile.And the elastic component 5 makes being converted between the first state and a second state of squeeze roll 3 linear The variation of elasticity, therefore, according to the thickness of different foamed cotton heads 20, uniform elastic becomes between the first state and a second state Change, so that the movement of squeeze roll is more steady, moreover, elastic component 5 but also squeeze roll is bigger in the extruding force of first state, is protected Squeezing effect is demonstrate,proved.

Also, the surface of the skewed slot 422 is additionally provided with 422 inside at least one kick 423 outstanding of down fold, this is small Protrusion 423 enables the axis 31 of squeeze roll 3 to be located in the nonvoluntary movement in position, also increases squeeze roll 3 and moves along skewed slot Frictional force when dynamic, and then increase the effect of extruding.

And those skilled in the art are it can be appreciated that the first end for being also possible to skewed slot 422 is located below, second end position In top, skewed slot is gradually distance from the mop rod 10 from the bottom up and extends.

Also, for the ease of squeezing the operation that frame 1 is moved up and down along mop rod 10, as shown in Figure 1, on the mop rod 10, position In the top for squeezing frame 1, it is arranged with actuating sleeve 6, which can move up and down along mop rod 10, and it is located at crowded frame 1 Top is connected between actuating sleeve 6 and crowded frame 1 by connecting rod 7, as long as therefore user drive actuating sleeve 6 along mop rod 10 It moves up and down, crowded frame 1 can be driven to move up and down along mop rod 10, it is easy to operate.

The foamed cotton head mop carries out rotation water squeezing using one big squeeze roll, and the diameter of squeeze roll is rationally arranged Best water squeezing can be obtained under the premise of saving cost with the ratio between foamed cotton head original depth and amount of compression Effect, and the extruding force suffered by the bottom surface of foamed cotton head from small to large and from big to small are squeezed so that water squeezing is more efficient Water effect is more preferable.And the setting of single squeeze roll, enable foamed cotton head to can smoothly enter into the channel pressings water outlet in crowded frame.

And the position between bottom surface when rationally the motion profile beginning provided with squeeze roll and foamed cotton head are not squeezed Relationship will not damage foamed cotton head, increase service life while guaranteeing water squeezing effect.

Foamed cotton hair can not pass through firmly from crowded frame in order to prevent, which can be located away first position and leave Channel, and then not extruding foaming cotton head bottom surface, are only located in channel in the second position, squeeze foamed cotton head.It is more square Just mop using and stores.

Moreover, in order to keep water squeezing effect more preferable, when which is located in channel, i.e., the second position when, also have certain Mobility so that squeezing frame when moving up and down, squeeze roll is different to the amount of compression of foamed cotton head.

Although the preferred embodiments of the utility model have been described above in detail, it is to be clearly understood that for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
