As shown in fig. 1-8, the present invention provides an embodiment of a sponge roller.

This sponge cylinder includes cylinder body 1 and installs in cylinder sponge 2 of 1 circumferential surface of cylinder body, and this cylinder sponge 2 is equipped with the distribution and divides into cellular inlayer 22 and adheres to the closely knit top layer 20 on cellular inlayer surface, it has a plurality of areas 201 that expose sponge inlayer 22 to distribute on the closely knit top layer 20.

Specifically, the area 201 of the exposed sponge inner layer 22 is generally out of plane with the solid skin layer 20. The areas 201 exposed out of the inner layer of the sponge are preferably uniformly distributed, so that the massage force of the contact surface of the roller sponge and the cleaning surface is basically the same when the roller sponge is used, and the phenomenon that the friction force is inconsistent in the use process, so that the work fluctuation of the motor is caused is avoided, and the service life is further influenced.

Through tests, the area ratio of the exposed sponge inner layer area 201 to the roller sponge surface layer 20 is 1/4-1/2, the distance between the adjacent exposed roller sponge inner layer areas 201 on the roller sponge surface is 0.2-1.0mm, the area of the exposed roller sponge inner layer area 201 is 0.002-0.01 square centimeter, and the balance between the cleaning effect and the noise and the balance between the cleaning effect and the service life are well considered.

During the use, because cylinder sponge surface is equipped with the recess, because it has a plurality of areas that expose the sponge inlayer to distribute on the closely knit top layer of this recess side, the regional existence that should expose the sponge inlayer for its cylinder sponge surface distribution has tiny recess, can provide certain frictional force, but is unlikely to produce great frictional force, produces great noise, compromises cleaning performance and noise and life's balance. Meanwhile, the grooves are sponge inner layers and have good water absorption, so that the cleaning effect is good when the cleaning is carried out, particularly when a liquid surface exists.

The grooves 21 can be arranged in a spiral shape, an arc shape or a triangular shape as required, and the cleaning effect is better through tests.

In order to improve the cleaning effect, grooves 21 are uniformly distributed on the surface of the roller sponge along the circumferential direction. As shown in fig. 5 and 6. One side 211 of the recess 21 forms a cleaning blade 23 with the sponge surface 20 of the cylinder. At least one side 211 of the groove 21 is an inclined plane, an included angle smaller than 90 degrees is formed between the inclined plane and the surface 20 of the roller sponge, and the cleaning scraper 23 structure formed in the test way has the advantage of better cleaning stubborn garbage. The cleaning blade 23 is adapted to the cleaning surface, i.e. the direction of the cleaning blade 23 is the same as the working rotation direction F of the sponge roller.

According to the requirement, the cross section of the groove 21 can be designed to be trapezoidal or the two side edges can be parallel.

Through tests, the cleaning effect is best when the area of the groove 21 occupies 1/4-1/2 of the circumferential surface of the roller sponge.

The grooves 21 are uniformly distributed along the length direction of the surface of the roller sponge 2, and the number of the grooves is set according to needs, such as a plurality of grooves. Since the two side surfaces of the groove 21 can be arranged vertically or approximately vertically, a cleaning blade 23 can be formed on the contact surface between the surface 2 and the side surface 211 of the roller sponge 2. Because cylinder sponge 2 forms more closely knit structure with the mould contact surface when the shaping, like this when the clearance, this clearance scraper B13 forms fine cutting action with stubborn rubbish on the clean face, improves the stubborn rubbish effect of clearance.

Meanwhile, as the cavity is formed in the groove 21, liquid on the cleaning surface can be scraped away, the cleaning surface cleaning device can also adapt to the scene that liquid on the cleaning surface is more, a plurality of areas 201 exposed out of the sponge inner layer 22 are distributed on the compact surface layer 20 on the surface of the roller sponge 2, and the cleaning surface cleaning device has a better cleaning effect when the cleaning surface with more liquid is provided. In addition, can collect the graininess solid through recess 21, when avoiding having mixed places such as graininess and powdery rubbish, because graininess rubbish exists makes cylinder sponge surface unable and clean face contact or contact surface less to unable disposable clearance together with graininess and other powdery rubbish, thereby improve clean efficiency.

As shown in fig. 8-9 d, the present invention further provides an embodiment of a sponge roller forming method.

The sponge roller forming method comprises the following steps of,

s10, a roller sponge forming step, namely forming roller sponge on the surface of a roller shaft core through a special die;

s11, polishing the surface of a sponge roller, namely polishing the compact surface layer at intervals when the roller sponge is molded, so that the compact surface layer 20 is partially worn and an area 201 of the inner layer of the roller sponge is exposed;

and S12, a sponge roller cutting step, namely cutting the sponge roller with the polished surface, and chamfering the two ends of the sponge roller for a certain length.

Specifically speaking, in the cylinder sponge shaping step, place cylinder axle core in sponge design sleeve earlier, fixed lid and first fixed step and cylinder axle core about the rethread, the fixed step of rethread is fixed with sponge design sleeve, make cylinder axle core and sponge design sleeve coaxial, and cylinder axle core surface and sponge design sleeve inner wall interval are even, pour into sponge material into the cavity (die cavity) that cylinder axle core and sponge design sleeve formed again, like PVA material, carry out the foam molding, form wave cambered surface structure on cylinder sponge surface.

During the process of forming the sponge shaping sleeve, the sponge and the mold cavity contact surface of the sponge shaping sleeve form a smooth surface layer on the sponge, as shown in fig. 2. Because the smooth surface layer friction of the roller sponge surface is small, the cleaning face cannot be effectively cleaned.

After the roller sponge is demoulded, a layer of membrane with the thickness of 0.2-0.5mm is formed on the surface, namely a compact surface layer 20, and the two problems are solved by the skin grinding: the contact area with the ground is increased, and the friction force is increased under the equal unit pressure and exceeds the friction force required by normal mopping cleaning; simultaneously, because the sponge surface has certain thickness and very strong tension, can extrude inside sponge layer in an inclosed space, restrain the elasticity that partial material itself has, and cylinder sponge during operation need not the extrusion sponge that stops, therefore rebound velocity is higher with the life-span requirement, also can release elasticity through polishing, promotes the wholeness ability.

Before the sponge roller cutting in step S12 is performed, the roller sponge surface is polished in step S12, so that the roller sponge surface is partially worn, and areas 201 exposing the inner layer of the roller sponge are uniformly distributed on the roller sponge surface, as shown in fig. 9a to 9 d. Can further reduce cylinder sponge surface friction, increase the transport rubbish ability simultaneously to further improve clean efficiency.

In the sponge roller surface polishing step, the interval between sponge inner layer areas distributed on the surface of the sponge roller is 0.2-1.0mm. The length of the chamfer is 3-7mm, and the range of the chamfer angle is 30-70 degrees.

In the step S10, in the step of forming the roller sponge, grooves 21 may be formed on the surface of the roller sponge, and the grooves 21 are uniformly distributed along the length direction of the surface of the roller sponge, and the number of the grooves 21 may be set as required, for example, several grooves may be provided. Since the two side surfaces of the groove 21 can be arranged vertically or approximately vertically, a cleaning blade 23 can be formed at the interface between the surface 20 and the side surface 211 of the roller sponge 2. Because cylinder sponge 2 forms more closely knit structure with the mould contact surface when the shaping, like this when the clearance, this clearance scraper 23 forms fine cutting action with stubborn rubbish on the cleaning surface, as shown in figure 6, when cylinder sponge 2 rotates to the F direction, this clearance scraper 23 can with the cleaning surface before form scrape cut the effect, from the actual ability with stubborn rubbish clearance, even can not one qualitatively clear up, also can clear up great stubborn rubbish cutting mode, thereby improve the stubborn rubbish effect of clearance. The grooves 21 can be arranged in a spiral shape, an arc shape or a triangular shape as required, and the cleaning effect is better through tests.

Meanwhile, as the cavity is formed in the groove 21, liquid on the cleaning surface can be scraped away, the cleaning surface cleaning device can also adapt to the scene that liquid on the cleaning surface is more, a plurality of areas 201 exposed out of the sponge inner layer 22 are distributed on the compact surface layer 20 on the surface of the roller sponge 2, and the cleaning surface cleaning device has a better cleaning effect when the cleaning surface with more liquid is provided. In addition, can collect the granular solid through recess 21, when avoiding having mixed places such as granule and likepowder rubbish, because granular rubbish exists and makes cylinder sponge surface unable and clean face contact or contact surface less to unable disposable clearance together with granule and other likepowder rubbish, thereby improve clean efficiency.

According to the requirement, the groove 21 can be designed to be in a trapezoidal section or one side of the groove is in an inclined plane structure, so that the cleaning effect of the cleaning scraper 23 can be improved, and the groove also has better liquid or granular solid carrying capacity in the cleaning process. The depth of the groove 21 is 1-2mm, and the width of the groove 23 is more than 0.5mm. And the width between two adjacent grooves 21 is more than 0.5mm, so that the cleaning effect is better through the test, and the cleaning efficiency and the service life of the roller sponge B1 are considered. The distance between two adjacent grooves 21 is the same as the width of the groove 31, and the cleaning effect and the wear resistance are good.

According to requirements, the area of the groove 21 occupies 1/4-1/2 of the circumferential surface of the roller sponge. The groove is spiral, arc or bar along roller sponge length direction, wherein spiral, arc are through experimental spiral, arc, can only partly contact on clean contact surface like this when clean, can reduce motor work load on the cylinder, do not influence clean effect yet simultaneously, have better effect.

At least one side surface of the groove 21 is an inclined surface, and an included angle smaller than 90 degrees is formed between the inclined surface and the surface of the roller sponge.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: it is to be understood that modifications may be made to the above-described arrangements in the embodiments or equivalents may be substituted for some of the features of the embodiments without departing from the spirit or scope of the present invention.
