[0026] Exemplary embodiments of the present application will be described hereinafter with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0027] In the field of household consumer goods, consumers have increasingly high requirements for the appearance of products, and texture appearance is increasingly used on the high-frequency touch shell of some household appliances, such as the handle of an electric kettle and the handle of an electric fan, because of its beautiful appearance, rich changes and many other advantages.

[0028] However, the current shell texture is generally obtained by spraying or pasting a film on the surface of the shell, and has high smoothness. In the case of frequent user touch, the friction between the skin and the contact surface is small, thereby reducing the user's touch feeling and poor anti-skid performance, which is not conducive to improving the user's use comfort.

[0029] Based on the above technical problems, the embodiment of the utility model is proposed, which can include a body 1 and a plurality of protrusions 2, the plurality of protrusions 2 are distributed on the body 1, wherein the height of the protrusion 2 extending outward along the surface of the body 1 is between 0.5 microns and 20 microns, the two protrusions 2 at adjacent positions form a groove 3, and the protrusion 2 and the groove 3 are smoothly connected. Thus, the protrusion 2 and the groove 3 cooperate to form a rough surface distributed on the body 1, and when the user's hand contacts the rough surface with smaller skin surface roughness, the user's touch feeling can be improved, and at the same time the friction of the hand holding part can be enhanced to prevent slipping during use of the appliance, thereby improving the use safety of the appliance.

[0030] REFERENCE Figures 1-4The shell can include a body 1 and a plurality of protrusions 2, the plurality of protrusions 2 are spaced apart on the body 1, wherein the height of the protrusion 2 extending outward along the surface of the body 1 is between 0.5 microns to 20 microns, the two protrusions 2 at adjacent positions form a groove 3, and the protrusion 2 and the groove 3 are smoothly connected.

[0031] In the shell, the body 1 can include a plurality of protrusions 2, and the body 1 serves as a structural support for the plurality of protrusions 2, and the plurality of protrusions 2 are spaced apart on the body 1. For example, the spaced apart distribution can include uniform distribution, and the uniform distribution can be understood as the regular distribution of the plurality of protrusions 2 on the body 1. For example, in the case that the cross-sectional shape of the body 1 is rectangular, the spaced apart distribution can be understood as the spaced apart distribution of the plurality of protrusions 2 along the length direction of the body 1, or the spaced apart distribution of the plurality of protrusions 2 along the width direction of the body 1. For another example, in the case that the cross-sectional shape of the body 1 is circular, the spaced apart distribution can be understood as the spaced apart distribution of the plurality of protrusions 2 along the radial direction of the body 1, or the spaced apart angular distribution of the plurality of protrusions 2 around the center of the body 1.

[0032] Referring to Figure 1 and Figure 2 As shown, the height H of the protrusion 2 extending outward along the first surface 101 of the body 1 is set to be between 0.5 microns and 20 microns, that is, the height of the plurality of protrusions 2 extending outward on the first surface 101 of the body 1 can be different, as long as it is distributed between 0.5 microns and 20 microns. For example, the height H of the first protrusion 2 extending outward along the body 1 is 0.5 microns, the height H of the second protrusion 2 extending outward along the body 1 is 5 microns, the height H of the third protrusion 2 extending outward along the body 1 is 10 microns, the height H of the fourth protrusion 2 extending outward along the body 1 is 20 microns, and the like. Those skilled in the art can determine the extension height of each protrusion 2 according to the above-mentioned extension height limit range, and this will not be limited here.

[0033] The two protrusions 2 at adjacent positions form a groove 3, and the protrusion 2 and the groove 3 are smoothly connected, wherein the smooth connection can be understood as that the area close to the groove 3 of the protrusion 2 is an arc, and the area close to the protrusion 2 of the groove 3 is also an arc, so that the surfaces of the two arcs at the connection of the protrusion 2 and the groove 3 are tangent. Therefore, the areas where the plurality of protrusions 2 are located and the plurality of grooves 3 are matched with each other, so as to form a rough surface covering the surface of the body 1. And by limiting the extension height of the protrusion 2, the roughness of the rough surface formed is smaller than the roughness of the skin of the user's hand, so as to form a skin-friendly touch feeling. When the user's hand touches the shell, a soft and delicate touch feeling like skin can be felt, and the friction between the hand and the shell can be increased, so as to prevent the user from slipping and the like when holding the shell. And the safety of the user when using the household appliance including the shell can be further improved.

[0034] In addition, the rough surface can also form a three-dimensional micro three-dimensional structure, so as to improve the appearance quality of the shell, integrate the appearance and good touch feeling, improve the use experience of the user, and be beneficial to improve the product applicability of the household appliance.

[0035] An optional utility model embodiment, referring to Figure 1 , Figure 3 and Figure 4 , the shell can include a body 1 and a plurality of protrusions 2, the plurality of protrusions 2 are distributed at intervals on the body 1, wherein the height of the protrusion 2 extending outward along the surface of the body 1 is between 0.5 microns and 20 microns, the two protrusions 2 at adjacent positions form a groove 3, and the protrusion 2 and the groove 3 are smoothly connected. And the protrusion 2 and the groove 3 are continuously arranged on the body 1 to form a rough surface completely covering the surface of the body 1.

[0036] In the utility model embodiment, the shell can include a body 1 and a plurality of protrusions 2, the body 1 serves as a structural support for the plurality of protrusions 2, and the plurality of protrusions 2 are distributed at intervals on the body 1. For example, the interval distribution can include uniform distribution, and the uniform distribution can be understood as that the plurality of protrusions 2 are regularly distributed on the body 1. For example, in the case that the cross-sectional shape of the body 1 is rectangular, the interval distribution can be understood as that the plurality of protrusions 2 are distributed at intervals along the length direction of the body 1, or the plurality of protrusions 2 are distributed at intervals along the width direction of the body 1. For another example, in the case that the cross-sectional shape of the body 1 is circular, the interval distribution can be understood as that the plurality of protrusions 2 are distributed at intervals along the radial direction of the body 1, or the plurality of protrusions 2 are distributed at intervals around the center of the body 1.

[0037] Referring to Figure 1 And Figure 2 As shown in the figure, the height H of the protrusions 2 extending outward from the body 1 is between 0.5 microns and 20 microns, that is, the height of the plurality of protrusions 2 extending outward from the surface of the body 1 can be different, as long as it is distributed between 0.5 microns and 20 microns. For example, the height H of the first protrusion 2 extending outward from the body 1 is 0.5 microns, the height H of the second protrusion 2 extending outward from the body 1 is 5 microns, the height H of the third protrusion 2 extending outward from the body 1 is 10 microns, the height H of the fourth protrusion 2 extending outward from the body 1 is 20 microns, and so on. Those skilled in the art can determine the extension height of each protrusion 2 according to the above-mentioned extension height limit, and will not be limited here.

[0038] The two protrusions 2 at adjacent positions form a groove 3, and the protrusions 2 and the grooves 3 are smoothly connected, where smoothly connected can be understood as the area near the groove 3 of the protrusion 2 is an arc, and the area near the protrusion 2 of the groove 3 is also an arc, so that the surfaces of the two arcs at the connection of the protrusion 2 and the groove 3 are tangent. Thus, the areas where the plurality of protrusions 2 are located cooperate with the plurality of grooves 3, thereby forming a rough surface covering the surface of the body 1. Wherein the protrusions 2 and the grooves 3 cooperate, which can be continuously arranged on the surface of the body 1. In other words, the plurality of protrusions 2 and the grooves 3 can cooperate with each other and be densely arranged on the surface of the body 1 until the surface of the body 1 is completely covered, thereby forming a rough surface completely covering the surface of the body 1.

[0039] Through the extension height limit of the protrusions 2, the roughness of the rough surface formed is less than the roughness of the user's hand skin, thereby forming a skin-friendly touch. When the user's hand touches any area of the surface of the shell, a soft and delicate touch can be felt, and the friction between the hand and the shell can be increased, preventing the user from slipping when holding the shell. And can further increase the safety of the user when using household appliances including the shell.

[0040] An alternative embodiment of the utility model, the protrusions 2 away from the top of the body 1 is a circular arc part 201.

[0041] In the embodiment of the utility model, the top of the protrusion 2 away from the body 1 is a circular arc part 201, the setting of the circular arc part 201 makes the top of the protrusion 2 have higher smoothness, and the protrusion 2 is the area directly contacted with the user's hand. In other words, the protrusion 2 and the groove 3 form a rough surface with certain roughness, and also reduce the sharpness when the protrusion 2 is contacted with the hand through the circular arc part 201, that is, the circular arc part 201 can increase the contact area with the hand, and can uniformly disperse the pressure applied by the user's hand to the protrusion 2, so that the comfort and uniformity of the user's hand touch feeling can be further improved.

[0042] An optional utility model embodiment, the diameter of the circular arc part 201 is set between 1 to 5 microns.

[0043] In the embodiment of the utility model, referring to Figure 1 and Figure 2 , the diameter R of the circular arc part 201 is set between 1 to 5 microns. That is, the diameters of the circular arc parts 201 corresponding to the plurality of protrusions 2 can be different, as long as they are distributed between 1 micron and 5 microns. For example, the diameter R of the circular arc part 201 of the first protrusion 2 is 1 micron, the diameter R of the circular arc part 201 of the second protrusion 2 is 2 microns, the diameter R of the circular arc part 201 of the third protrusion 2 is 3 microns, the diameter R of the circular arc part 201 of the fourth protrusion 2 is 4 microns, and the diameter R of the circular arc part 201 of the fifth protrusion 2 is 5 microns, etc. Those skilled in the art can determine the diameter of the circular arc part 201 of each protrusion 2 according to the above diameter limitation range, and will not be limited here.

[0044] Setting the diameter of the circular arc part 201 between 1 micron and 5 microns can ensure that the plurality of protrusions 2 are arranged at intervals to form a certain roughness. If the diameter of the circular arc part 201 is less than 1 micron, the diameter of the circular arc part 201 of the protrusion 2 is too small, which increases the sharpness of the protrusion 2, thereby reducing the comfort of the user touching the rough surface. If the diameter of the circular arc part 201 is greater than 5 microns, the diameter of the circular arc part 201 of the protrusion 2 is too large, which increases the smoothness of the protrusion 2, thereby reducing the skin-friendly feeling of the user touching the rough surface.

[0045] An optional utility model embodiment, referring to Figure 1 , Figure 2 and Figure 3As shown, the shell comprises a body 1 and a plurality of protrusions 2, the plurality of protrusions 2 are spaced apart on the body 1, wherein the height of the protrusions 2 extending outward along the surface of the body 1 is between 0.5 microns to 20 microns, the groove 3 is formed between two protrusions 2 at adjacent positions, and the protrusions 2 and the groove 3 are smoothly connected, and the width of the groove 3 formed between two protrusions 2 at adjacent positions is set to be between 10 microns to 500 microns.

[0046] In the embodiment of the utility model, the shell can include a body 1 and a plurality of protrusions 2, the body 1 is the structural support of the plurality of protrusions 2, and the plurality of protrusions 2 are spaced apart on the body 1. For example, the spaced apart distribution can include uniform distribution, and the uniform distribution can be understood as the regular distribution of the plurality of protrusions 2 on the body 1. For example, in the case that the cross-sectional shape of the body 1 is rectangular, the spaced apart distribution can be understood as the spaced apart distribution of the plurality of protrusions 2 along the length direction of the body 1, or the spaced apart distribution of the plurality of protrusions 2 along the width direction of the body 1. For another example, in the case that the cross-sectional shape of the body 1 is circular, the spaced apart distribution can be understood as the spaced apart distribution of the plurality of protrusions 2 along the radial direction of the body 1, or the spaced apart angular distribution of the plurality of protrusions 2 around the center of the body 1.

[0047] Referring to Figure 1 and Figure 2 As shown, the height H of the protrusions 2 extending outward along the body 1 is set to be between 0.5 microns to 20 microns, that is, the height of the plurality of protrusions 2 extending outward on the surface of the body 1 can be different, as long as it is distributed between 0.5 microns to 20 microns. For example, the height H of the first protrusion 2 extending outward along the body 1 is 0.5 microns, the height H of the second protrusion 2 extending outward along the body 1 is 5 microns, the height H of the third protrusion 2 extending outward along the body 1 is 10 microns, the height H of the fourth protrusion 2 extending outward along the body 1 is 20 microns, and the like. The skilled in the art can determine the extension height of each protrusion 2 according to the above-mentioned limited range of extension height, which is not limited here.

[0048] The two protrusions 2 at adjacent positions form a groove 3 therebetween, and the protrusion 2 and the groove 3 are smoothly connected therebetween, which can be understood as that the area of the protrusion 2 close to the groove 3 is an arc, and the area of the groove 3 close to the protrusion 2 is also an arc, so that the surfaces of the two arcs at the connection of the protrusion 2 and the groove 3 are tangent. Thus, the areas where the plurality of protrusions 2 are located and the plurality of grooves 3 are matched with each other, so as to form a rough surface covering the surface of the body 1. The matching of the protrusion 2 and the groove 3 can be continuously arranged on the surface of the body 1. In other words, the plurality of protrusions 2 and the grooves 3 can be densely arranged on the surface of the body 1 until the surface of the body 1 is completely covered, so as to form a rough surface completely covering the surface of the body 1.

[0049] Referring to Figure 1 and Figure 2 As shown, the width D of the groove 3 formed between the two protrusions 2 at adjacent positions is arranged between 10 microns and 500 microns, that is, the widths of the grooves 3 formed between the two protrusions 2 at adjacent positions in different groups can be different, as long as they are distributed between 10 microns and 500 microns. For example, the width of the groove 3 formed between the two protrusions 2 at adjacent positions in a first group is 10 microns, the width of the groove 3 formed between the two protrusions 2 at adjacent positions in a second group is 50 microns, the width of the groove 3 formed between the two protrusions 2 at adjacent positions in a third group is 100 microns, the width of the groove 3 formed between the two protrusions 2 at adjacent positions in a fourth group is 300 microns, and the width of the groove 3 formed between the two protrusions 2 at adjacent positions in a fifth group is 500 microns. Those skilled in the art can determine the width of the groove 3 according to the above-mentioned width limitation range, and the width of the groove 3 is not limited herein.

[0050] By limiting the width of the groove 3 to be between 10 microns and 500 microns, the distance between the two adjacent protrusions 2 can be appropriate, so that a rough surface with a comfortable hand feeling can be formed on the surface of the body 1. Since the width D of the groove 3 can be understood as the distance between the two protrusions 2 at adjacent positions, if the width of the groove 3 is less than 10 microns, the distance between the two protrusions 2 at adjacent positions is too small, and the extension height thereof cannot be arranged within the range of 0.5 microns to 20 microns, so that the smooth connection between the arc portion 201 of the protrusion 2 and the protrusion 2 cannot be achieved, thereby increasing the sharpness of the protrusion 2 and reducing the user's comfort. If the width of the groove 3 is greater than 500 microns, the distance between the two adjacent protrusions 2 is too large, which reduces the number of protrusions 2 in the same area on the surface of the shell, thereby reducing the skin-friendly touch feeling of the rough surface.

[0051] The roughness of the rough surface formed by the extension height limitation of the protrusions 2, the diameter limitation of the circular arc part 201 and the width limitation of the groove 3 formed between two protrusions 2 at adjacent positions is smaller than the roughness of the skin of the user's hand, and the rough surface has a skin-friendly touch. When the user's hand touches any area of the surface of the shell, a soft and delicate touch can be felt, and the friction between the hand and the shell can be increased, preventing the user from slipping when holding the shell. And it can further increase the safety of the user when using the household appliance including the shell.

[0052] An optional utility model embodiment, referring to Figure 1 、 Figure 2 and Figure 3 , the width of the groove 3 formed between two protrusions 2 at adjacent positions is set to be between 10 microns and 500 microns. The cross-sectional shape of the plurality of protrusions 2 and the groove 3 is wavy.

[0053] In the utility model embodiment, by limiting the width of the groove 3 to be between 10 microns and 500 microns, the distance between the two adjacent protrusions 2 can be appropriately ensured, so that a comfortable rough surface with bumps and depressions can be formed on the surface of the body 1. Since the width D of the groove 3 can be understood as the distance between the two adjacent protrusions 2, if the width of the groove 3 is less than 10 microns, the distance between the two adjacent protrusions 2 is too small, and the extension height of the protrusions 2 cannot be set to be within the range of 0.5 microns to 20 microns, so that the smooth connection between the circular arc part 201 of the protrusion 2 and the protrusion 2 cannot be realized, thereby increasing the sharpness of the protrusion 2 and reducing the user's comfort. If the width of the groove 3 is greater than 500 microns, the distance between the two adjacent protrusions 2 is too large, the number of protrusions 2 in the same area on the surface of the shell is reduced, and the skin-friendly touch of the rough surface is reduced.

[0054] The cross-sectional shape of the plurality of protrusions 2 and the groove 3 is wavy, that is, the protrusion 2 is an arc surface away from the surface of the body 1, the groove wall of the groove 3 is also an arc surface, and the protrusion 2 and the groove 3 are smoothly connected, thereby reducing the sharpness of the rough surface, facilitating the user's hand to hold, not easy to slip, and improving the comfort of the user's hand contact, thereby improving the user's experience of the product and improving the product performance of the shell.

[0055] An optional utility model embodiment, the body 1 is made of one of the following materials: acrylonitrile-butadiene-styrene copolymer material and polypropylene material.

[0056] In the embodiment of the utility model, the acrylonitrile-butadiene-styrene copolymer material (ABS) is a synthetic resin made of acrylonitrile, butadiene and styrene.

The molten material can be understood as a material in a molten state. An inner surface of the mold is formed with a rough surface by laser radiation. For example, according to the above description of the shell, the rough surface of the inner surface of the mold is matched with the shape of the rough surface of the shell, so that the shell can be processed by injecting the molten material into the mold.

[0070] In some embodiments, the mold can be made of a metal material with good hardness, heat resistance and wear resistance. For example, the mold can be made of tool steel material (such as SKD11). For another example, the mold can be made of hard alloy.

[0071] The rough surface on the mold can be obtained by laser radiation process, such as femtosecond laser or ultrafast laser surface processing of the plate-shaped mold. In other embodiments, the mold can be processed by combining metal etching and laser radiation process. For example, the initial rough inner surface is first formed by etching processing, and then the initial rough inner surface is processed again by laser, for example, sharp area, so that the subsequent convex 2 of the shell is more rounded.

[0072] S503, cooling the mold to obtain a solidified shell, wherein the shell includes a body 1 and a plurality of convexes 2, the plurality of convexes 2 are distributed on the body 1, the height of the convex 2 extending outward along the surface of the body 1 is between 0.5 microns and 20 microns, two convexes 2 at adjacent positions form a groove 3, and the convex 2 and the groove 3 are smoothly connected.

[0073] The utility model embodiment, after the molten material is injected into the mould, the mould can be cooled, so that the molten material is solidified and formed, obtains the shell with rough surface, at this time the solidified shell is taken out from the mould, obtains the final product's shell. Among them, the shell can include body 1 and a plurality of protrusions 2, the body 1 is as a plurality of the structure support of protrusion 2, a plurality of protrusions 2 are spaced distribution on the body 1. For example, spaced distribution can include uniform distribution, and uniform distribution can be understood as a plurality of protrusions 2 are regularly distributed on the body 1. For example, in the case where the cross-sectional shape of the body 1 is rectangular, spaced distribution can be understood as a plurality of protrusions 2 are spaced distribution along the length direction of the body 1, or a plurality of protrusions 2 are spaced distribution along the width direction of the body 1. For example, in the case where the cross-sectional shape of the body 1 is circular, spaced distribution can be understood as a plurality of protrusions 2 are spaced distribution along the radial direction of the body 1, or a plurality of protrusions 2 are spaced angular distribution around the center of the body 1.

[0074] Referring to Figure 1 And Figure 2 As shown, the height H of the protrusion 2 extending outward along the body 1 is set between 0.5 microns and 20 microns, that is, the height of a plurality of protrusions 2 extending outward on the surface of the body 1 can be different, as long as it is distributed between 0.5 microns and 20 microns. For example, the height H of the first protrusion 2 extending outward along the body 1 is 0.5 microns, the height H of the second protrusion 2 extending outward along the body 1 is 5 microns, the height H of the third protrusion 2 extending outward along the body 1 is 10 microns, the height H of the fourth protrusion 2 extending outward along the body 1 is 20 microns, etc. Those skilled in the art can determine the extension height of each protrusion 2 according to the above extension height limit range, which is not limited here.

[0075] The two protrusions 2 between adjacent positions form a groove 3, and the protrusions 2 and the groove 3 are smoothly connected, wherein the smooth connection can be understood as that the area close to the groove 3 of the protrusion 2 is an arc, and the area close to the protrusion 2 of the groove 3 is also an arc, so that the surfaces of the two arcs at the connection of the protrusion 2 and the groove 3 are tangent. Therefore, the areas where the plurality of protrusions 2 are located cooperate with the plurality of grooves 3, so as to form a rough surface covering the surface of the body 1. And by limiting the extension height of the protrusions 2, the roughness of the rough surface formed is smaller than the roughness of the skin of the user's hand, so as to form a skin-friendly touch. When the user's hand touches the shell, a soft and delicate touch can be felt, and the friction between the hand and the shell can be increased, so as to prevent the user from slipping and the like when holding the shell. And the safety of the user when using the household appliance including the shell can be further increased.

[0076] An optional utility model embodiment, referring to Figure 6 The manufacturing method of the shell can comprise:

[0077] S601, solid material is added to an injection molding machine, and the injection molding temperature of the injection molding machine is set to be between 200 degrees Celsius and 250 degrees Celsius, and the injection molding pressure is set to be between 50 MPa and 100 MPa, to obtain a molten material, wherein the solid material is one of acrylonitrile-butadiene-styrene copolymer material and polypropylene material.

[0078] In the utility model embodiment, the solid material can be acrylonitrile-butadiene-styrene copolymer material or polypropylene material. Acrylonitrile-butadiene-styrene copolymer material (ABS) is a synthetic resin made of acrylonitrile, butadiene and styrene. It has good heat resistance, wear resistance, and can be processed by blow molding, extrusion, injection molding and other processes, and has a wide range of applications. Polypropylene (PP) is a semi-crystalline thermoplastic polymer made of propylene monomer by polycondensation. It has good heat resistance, wear resistance and mechanical strength, and can also be processed by blow molding, extrusion, injection molding and other processes, and has a wide range of applications. Therefore, when the shell is made of acrylonitrile-butadiene-styrene copolymer material and polypropylene material, the wear resistance of the shell can be ensured, and the roughness of the rough surface formed by the dense protrusions 2 is relatively uniform, so that the protrusions 2 will not be broken or damaged when the user's hand frequently touches them.

[0079] Correspondingly, when the injection temperature of the injection molding machine is set between 200 degrees Celsius and 250 degrees Celsius, and the injection pressure is set between 50 megapascals and 100 megapascals, the acrylonitrile-butadiene-styrene copolymer material and the polypropylene material can be fully melted, and the later melted material can be fully filled in each region of the mold.

[0080] S602, a mold is provided, wherein a surface of the mold is formed into a rough inner surface by laser radiation.

[0081] S603, the molten material is injected into the mold.

[0082] In the embodiments of the utility model, the inner surface of the mold is formed into a rough surface by laser radiation. For example, referring to the above description of the shell, the rough surface of the inner surface of the mold is adapted to the shape of the rough surface of the shell, so that the shell can be processed by injecting the molten material into the mold.

[0083] In some embodiments, the mold can be made of a metal material with good hardness, heat resistance and wear resistance. For example, the mold can be made of tool steel material (such as SKD11). For another example, the mold can be made of hard alloy.

[0084] The rough surface on the mold can be obtained by laser radiation process, such as femtosecond laser or ultrafast laser surface processing of the plate-shaped mold. In other embodiments, the mold can be processed by combining metal etching and laser radiation process. For example, first, an initial rough inner surface is formed by etching processing, and then the initial rough inner surface is processed again by laser, such as sharp area, so that the subsequent shell protrusion 2 is more rounded.

[0085] S604, the mold is cooled to obtain a solidified shell, wherein the shell includes a body 1 and a plurality of protrusions 2, the plurality of protrusions 2 are distributed on the body 1, the height of the protrusion 2 extending outward along the surface of the body 1 is between 0.5 microns and 20 microns, two protrusions 2 at adjacent positions form a groove 3, and the protrusion 2 and the groove 3 are smoothly connected.

[0086] The utility model discloses an embodiment, after the molten material is injected into the mould, can carry out the cooling to the mould, thereby make the molten material solidification forming, obtain the shell with rough surface, take out the shell after solidification from the mould, obtain the shell of final product. Among them, the shell includes body 1 and a plurality of protruding 2, a plurality of protruding 2 interval distribution is on body 1, the height of protruding 2 along the surface of body 1 outward extension is between 0.5 microns to 20 microns, the groove 3 is formed between the two protruding 2 of adjacent position, and, protruding 2 and the smooth link of groove 3, the width of groove 3 formed between the two protruding 2 of adjacent position is set between 10 microns to 500 microns. The top of protruding 2 away from body 1 is arc part 201. And the diameter of arc part 201 is set between 1 to 5 microns.

[0087] The shell can include body 1 and a plurality of protruding 2, the body 1 is as a plurality of the structure support of protruding 2, a plurality of protruding 2 interval distribution is on body 1. For example, interval distribution can include uniform distribution, uniform distribution can be understood as a plurality of protruding 2 regularly distributed on body 1. For example, in the case where the cross-sectional shape of body 1 is rectangular, interval distribution can be understood as a plurality of protruding 2 interval distribution along the length direction of body 1, or a plurality of protruding 2 interval distribution along the width direction of body 1. For example, in the case where the cross-sectional shape of body 1 is circular, interval distribution can be understood as a plurality of protruding 2 interval distribution along the radial direction of body 1, or a plurality of protruding 2 angle distribution around the center of body 1.

[0088] Referring to Figure 1 And Figure 2 As shown in the figure, the height H of protruding 2 outward extension along body 1 is set between 0.5 microns to 20 microns, that is, a plurality of protruding 2 outward extension height on the surface of body 1 can be different, as long as it is distributed between 0.5 microns to 20 microns. For example, the height H of first protruding 2 outward extension along body 1 is 0.5 microns, the height H of second protruding 2 outward extension along body 1 is 5 microns, the height H of third protruding 2 outward extension along body 1 is 10 microns, the height H of fourth protruding 2 outward extension along body 1 is 20 microns, etc. Those skilled in the art can determine the extension height of each protruding 2 according to the above extension height limit range, which is not limited here.

[0089] The two protrusions 2 between adjacent positions form a groove 3, and the protrusions 2 and the groove 3 are smoothly connected, which can be understood as that the area close to the groove 3 of the protrusion 2 is an arc, and the area close to the protrusion 2 of the groove 3 is also an arc, so that the surfaces of the two arcs at the connection of the protrusion 2 and the groove 3 are tangent. Thus, the areas where the plurality of protrusions 2 are located cooperate with the plurality of grooves 3, thereby forming a rough surface covering the surface of the body 1. Wherein, the protrusions 2 and the grooves 3 can be continuously arranged on the surface of the body 1. In other words, the plurality of protrusions 2 and the grooves 3 can be densely arranged on the surface of the body 1 until the surface of the body 1 is completely covered, thereby forming a rough surface completely covering the surface of the body 1.

[0090] The protrusion 2 is a circular arc portion 201 away from the top of the body 1. The circular arc portion 201 is arranged to make the top of the protrusion 2 have a higher smoothness, and the protrusion 2 is the area directly contacting the user's hand. In other words, the protrusion 2 and the groove 3 form a rough surface with a certain roughness, and also reduce the sharpness of the protrusion 2 when contacting the hand through the circular arc portion 201. That is, the circular arc portion 201 can increase the contact area with the hand, and can uniformly disperse the pressure applied by the user's hand to the protrusion 2, thereby further improving the comfort and uniformity of the user's hand touch.

[0091] The diameter R of the circular arc portion 201 is arranged to be between 1 to 5 microns. That is, the diameters of the circular arc portions 201 corresponding to the plurality of protrusions 2 can be different, as long as they are distributed between 1 micron to 5 microns. For example, the diameter R of the circular arc portion 201 of the first protrusion 2 is 1 micron, the diameter R of the circular arc portion 201 of the second protrusion 2 is 2 microns, the diameter R of the circular arc portion 201 of the third protrusion 2 is 3 microns, the diameter R of the circular arc portion 201 of the fourth protrusion 2 is 4 microns, and the diameter R of the circular arc portion 201 of the fifth protrusion 2 is 5 microns, etc. Those skilled in the art can determine the diameter of the circular arc portion 201 of each protrusion 2 according to the above diameter limitation range, and will not be limited here.

[0092] The diameter of the arc part 201 is set between 1 micron and 5 microns, which can ensure that the plurality of protrusions 2 are arranged at intervals to form a certain roughness. If the diameter of the arc part 201 is less than 1 micron, the diameter of the arc part 201 of the protrusion 2 is too small, which increases the sharpness of the protrusion 2, thereby reducing the comfort of the user touching the rough surface. If the diameter of the arc part 201 is greater than 5 microns, the diameter of the arc part 201 of the protrusion 2 is too large, which increases the smoothness of the protrusion 2, thereby reducing the skin-friendly touch of the user touching the rough surface.

[0093] Referring to Figure 1 and Figure 2 As shown in the drawings, the width D of the groove 3 formed between two protrusions 2 at adjacent positions is set between 10 microns and 500 microns, that is, the width of the groove 3 formed between two protrusions 2 at adjacent positions in multiple groups can be different, as long as it is distributed between 10 microns and 500 microns. For example, the width of the groove 3 formed between two protrusions 2 at adjacent positions in the first group is 10 microns, the width of the groove 3 formed between two protrusions 2 at adjacent positions in the second group is 50 microns, the width of the groove 3 formed between two protrusions 2 at adjacent positions in the third group is 100 microns, the width of the groove 3 formed between two protrusions 2 at adjacent positions in the fourth group is 300 microns, and the width of the groove 3 formed between two protrusions 2 at adjacent positions in the fifth group is 500 microns. Those skilled in the art can determine the width of the groove 3 according to the above-mentioned width limitation range, and will not be limited here.

[0094] By limiting the width of the groove 3 to between 10 microns and 500 microns, the distance between the two adjacent protrusions 2 can be appropriate, so that a comfortable rough surface with bumps and depressions can be formed on the surface of the body 1. Since the width D of the groove 3 can be understood as the distance between the two adjacent protrusions 2, if the width of the groove 3 is less than 10 microns, the distance between the two adjacent protrusions 2 is too small, and the extension height thereof is set to be within the range of 0.5 microns to 20 microns, which cannot achieve smooth connection between the arc part 201 of the protrusion 2 and the protrusion 2, thereby increasing the sharpness of the protrusion 2 and reducing the comfort of the user. If the width of the groove 3 is greater than 500 microns, the distance between the two adjacent protrusions 2 is too large, which reduces the number of protrusions 2 in the same area on the surface of the shell, thereby reducing the skin-friendly touch of the rough surface.

[0095] The roughness of the rough surface formed by the extension height limitation of the protrusions 2, the diameter limitation of the circular arc part 201 and the width limitation of the groove 3 formed between two protrusions 2 at adjacent positions is smaller than the roughness of the skin of the user's hand, and the rough surface has a skin-friendly touch. When the user's hand touches any area of the surface of the shell, a soft and delicate touch can be felt, and the friction between the hand and the shell can be increased, preventing the user from slipping when holding the shell. And it can further increase the safety of the user when using the household appliance including the shell.

[0096] In summary, the embodiments of the present application disclose a manufacturing method of a shell, which can include first providing a mold and a molten material, and forming a rough inner surface on the surface of the mold by laser. Then the molten material is injected into the mold. Finally, the mold is cooled to obtain a solidified shell, wherein the shell includes a body 1 and a plurality of protrusions 2, the plurality of protrusions 2 are distributed on the body 1, the height of the protrusions 2 extending outward along the surface of the body 1 is between 0.5 microns and 20 microns, a groove 3 is formed between two protrusions 2 at adjacent positions, and the protrusions 2 and the groove 3 are smoothly connected. Thus, the protrusions 2 and the groove 3 cooperate to form a rough surface distributed on the body 1, and when the user's hand contacts the rough surface with a roughness smaller than the skin surface, the user's touch can be improved, and at the same time the friction of the hand holding part can be enhanced to prevent slipping when using the appliance, thereby improving the safety of the appliance.
