As shown in fig. 1, the main body 1 is a sponge base, and a hand plate 11 is fixedly connected to one end of the sponge base, which is far away from the abrasive layer 2. Grip this cleaning block through palm 11 can be better to conveniently operate the cleaning block so that abrasive layer 2 and household utensils contact, clean household utensils.

As shown in fig. 1, in order to protect the side surface of the sponge base, a protective layer 3 is further disposed on the body 1 (i.e., the sponge base), and the protective layer 3 is annular and the lower end of the annular protective layer is connected to the abrasive layer 2. The protective layer 3 separates the side surface of the body 1 from the vessel to ensure that the side surface of the body 1 does not contact with the vessel during cleaning, so as to avoid friction and protect the vessel.

As shown in fig. 1 and 2, the protective layer 3 includes a second glue layer and walnut shell particles (walnuts are walnuts) attached to the surface of the second glue layer far away from the body 1. Like the first glue layer 4, the second glue layer is a water-soluble environment-friendly glue layer (consistent with the first glue layer 4, the water-soluble environment-friendly glue is acrylic resin), the water-soluble environment-friendly glue is coated on the body 1, and then the walnut shell particles are fixed by the water-soluble environment-friendly glue; further, the protective layer 3 can also perform a cleaning function while performing a protective function.

Furthermore, the pecan shell particles in the abrasive layer 2 are formed by crushing pecan shells, and the pecan shell particles in the protective layer 3 are formed by crushing pecan shells; the pecan shells and the walnut shells are crushed and then subjected to deoiling treatment. The particles made of the pecan shells have higher strength and are mainly used for cleaning, and the particles made of the pecan shells can also play a certain cleaning function, but are heavier to protect the sponge matrix and avoid friction.

As shown in fig. 2 and 3, the pecan shell particles comprise large particles 7 with a particle size of 0.8-1 mm and small particles 8 with a particle size of 0.4-0.7 mm, the large particles 7 enclose a plurality of first grinding blocks 9, the small particles 8 enclose a plurality of second grinding blocks 10, and the first grinding blocks 9 and the second grinding blocks 10 are arranged in an interval manner. The large particles 7 are set to have a compression limit of 25 to 30kgf and the small particles 8 are set to have a compression limit of 18 to 24kgf, so that cleaning regions having different strengths are formed on the sponge base, or the large particles 7 alone or the small particles 8 alone may be used to form the abrasive layer 2.

Particularly, the walnut shell particles on the protective layer 3 have a particle size of 0.8-1 mm and a compressive limit of 20-25 kgf, wherein when the walnut shell particles have a particle size of 0.9mm, the average compressive limit is 23.19 kgf;

or the walnut shell particles on the protective layer 3 have the particle size of 0.4-0.7 mm and the compression limit of 16-18 kgf, namely the compression limit of the walnut shell particles is lower than that of the pecan shell particles, wherein when the particle size of the walnut shell particles is 0.5mm, the average compression limit of the walnut shell particles is 17.11 kgf.

As shown in fig. 2 and 3, in particular, when the cleaning block is processed, the pecan shell particles used are embedded in the first glue layer 4, meanwhile, the pecan shell particles are partially embedded in the sponge matrix (large particles 7 are embedded in the body 1 as shown in fig. 3), the pecan shell particles and the sponge matrix are bonded together through water-soluble glue, and the pecan shell particles are partially higher than the formed first glue layer 4, so that the connection between the abrasive layer 2 and the sponge matrix is more stable, meanwhile, the pecan shell particles have a good cleaning effect, and particularly, the processing process of the pecan shell particles and the processing process of the pecan shell particles are similar.

The arrangement is such that the abrasive layer 2 can be replaced, so that the cleaning block can maintain normal cleaning function for a long time; wherein the net curtain layer 12 that sets up can be one of gauze material, thin wire net and organic glass fiber etc. can provide adnexed basis for water-soluble glue, large granule 7 and tiny particle 8 to make abrasive material layer 2 more stable (likewise, also can set up similar net curtain layer 12 in the protective layer 3, improve protective layer 3's stability).

Particularly, the arranged inserting sheets 13 are iron sheets or plastic sheets and the like, and the mechanical strength of the cleaning block can be improved after the cleaning block is inserted into the body 1, as shown in fig. 5, the four inserting sheets 13 are all positioned in the enclosure of the protective layer 3, and the protective layer 3 and the abrasive layer 2 are tightly abutted together with the aid of the inserting sheets 13, so that the lower end of the body 1 is wrapped; the insert 13 is further provided with a through hole 14 so as not to affect the entry and discharge of water in the body 1.

The cleaning block provided by the embodiment of the invention has the following beneficial effects:

2) the abrasive layer 2 does not contain alumina, silicon carbide, plastic particles and the like, and has degradability, so that the abrasive layer is more environment-friendly;

3) the adopted pecan shell abrasive has very stable chemical property, does not contain toxic substances, has small dissolution in acid, alkali and water, has the loss of 2.45 percent (4.62 percent) of pecan shell particles in 15 percent (mass fraction) hydrochloric acid solution and the loss rate of 2.15 percent (3.72 percent) of pecan shell particles in 20 percent (mass fraction) sodium hydroxide solution, does not cause water quality deterioration, and is more environment-friendly.

In particular, the pecan shell particles and walnut shell particles in this example have several processing modes as follows:

process one (i.e., this embodiment adopts the manner):

the treatment process of the hickory shells and the walnut shells comprises the following steps: cleaning pecan shells or walnut shells with deionized water (brushing off attachments on the inner wall and the outer wall of the pecan shells), adding deionized water, boiling for 1.5h, draining water, soaking with alkaline water for 1.5h while stirring, draining water after soaking, drying to constant weight, taking out, cooling to room temperature, and then performing jet milling. Thus, grease attached to the pecan shells or the walnut shells can be removed (namely the deoiling treatment), and pigments in the pecan shells or the walnut shells can be removed, so that the pecan shell particles or the walnut shell particles have better cleaning performance;

wherein, the alkaline water soaking can be replaced by soaking in 5 percent sodium hydroxide solution for 0.5h, and the time is shorter.

And (5) processing:

if the pecan shells or the walnut shells are directly washed by deionized water and dried to constant weight, and then are subjected to jet milling, the stability of the obtained pecan shell particles or the walnut shell particles is reduced, specifically: the loss of the pecan shell particles in 15 percent (mass fraction) hydrochloric acid solution is 5.12 percent (the walnut shell particles are 6.91 percent), and the loss rate of the pecan shell particles in 20 percent (mass fraction) sodium hydroxide solution is 4.84 percent (the walnut shell particles are 5.67 percent);

and (3) treatment III:

if the pecan shells or the walnut shells are directly washed by deionized water and then cooked for 1.5h, and then dried to constant weight and then pulverized by airflow, the stability of the obtained pecan shell particles or the walnut shell particles is reduced, specifically: the loss of the pecan shell particles in 15 percent (mass fraction) hydrochloric acid solution is 4.41 percent (the walnut shell particles are 5.72 percent), and the loss rate of the pecan shell particles in 20 percent (mass fraction) sodium hydroxide solution is 3.97 percent (the pecan shell particles are 4.89 percent).

In the second treatment, when the large particles 7 had a particle size of 0.8mm and the small particles 8 had a particle size of 0.5mm, the average compression limit of the large particles 7 was 22.35kgf and the average compression limit of the small particles 8 was 19.85 kgf;

the average compression limit of the walnut shell particles on the protective layer 3 was 18.74kgf when the particle size of the walnut shell particles was 0.9mm, or 15.09kgf when the particle size of the walnut shell particles on the protective layer 3 was 0.5 mm.

In the third treatment, when the large particles 7 had a particle size of 0.8mm and the small particles 8 had a particle size of 0.5mm, the average compression limit of the large particles 7 was 25.02kgf and the average compression limit of the small particles 8 was 20.96 kgf;

the average compression limit of the walnut shell particles on the protective layer 3 was 20.14kgf when the particle size of the walnut shell particles was 0.9mm, or 16.42kgf when the particle size of the walnut shell particles on the protective layer 3 was 0.5 mm.

Among the three treatments, the comparative data show that the compression resistance limit of the large particles and the small particles of the first treatment (i.e. the cleaning block provided by the embodiment of the invention) and the walnut shell particles is the maximum, and the acid resistance and the alkali resistance are also the optimal, and the cleaning block prepared by treating the walnut shell particles (including the large particles 7 and the small particles 8) and the walnut shell particles (i.e. the cleaning block provided by the invention) has better cleaning performance and better environmental protection performance;

the two treatments are compared with the first treatment without treatments such as cooking, deoiling and the like, the compression limit parameter and the acid and alkali resistance parameters of the first treatment are the lowest, and the three treatments are compared with the first treatment without deoiling treatment, but the compression limit parameter and the acid and alkali resistance parameters of the second treatment are better than those of the second treatment, which shows that the cooking and deoiling treatment is helpful for improving the compression limit parameter and can improve the acid and alkali resistance of the walnut shell particles and the pecan shell particles, namely, the cleaning purpose can be achieved by adopting the cleaning blocks of the pecan shell particles (comprising large particles 7 and small particles 8) and the pecan shell particles provided by the second treatment and the third treatment, but the cleaning performance and the environmental protection performance of the cleaning blocks are lower than those provided by the invention.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
