[0059] The measuring tool 20 includes a plurality of measuring pieces 21, each measuring piece 21 is formed with a measuring portion 211, and the measuring portion 211 of each measuring piece 21 has different specifications and sizes. Each measuring piece 21 corresponds to one of the quantitative material slots 102 in each quantitative material slot, that is, after measuring the size of the ear canal with measuring pieces 21 of different specifications and sizes, one of the measuring pieces 21 is selected, and the selected measuring piece 21 is selected to correspond to the selected quantitative material slot 102;

[0060] The molding material 30 includes a first material 31 and a second material 32. The first material 31 and the second material 32 can be filled in a quantitative material slot 102 corresponding to one of the measuring pieces 21, that is, filled in the selected quantitative material slot 102. The selected quantitative material slot 102 is filled with the first material 31 and the second material 32. The amount filled is the amount of the measured ear canal size and the amount used to make the earplug. The first material 31 and the second material 32 can be taken out from the selected quantitative material slot 102 and mixed and kneaded to form a mixed material 301.

[0061] The storage component has a space, for example, a bag or a box, and any storage component that can store items can be used as the storage component of the present invention. The structure of the storage component is prior art, so it will not be described in further detail. The storage component can place the quantitative component, the measuring tool 20 and the molding material 30 in each storage component respectively.

[0062] like Figure 1 and Figure 2 FIG. 2 shows another embodiment of the earplug manufacturing kit of the present invention, wherein the earplug manufacturing kit at least includes a material 10 , a measuring tool 20 and a molding material 30 .

[0063] The material 10 can be a body of any shape and has a plurality of walls, and a plurality of slots 101 and a plurality of quantitative material slots 102 are formed concavely on one wall. Figure 1 , Figure 2 The specific embodiment shown in FIG. 1 has five slots 101 and five quantitative material slots 102, and the volume formed by the concave in each quantitative material slot 102 is different, such as Figure 1 , Figure 2 As shown, each quantitative material slot 102 can be arranged in sequence according to the volume size, and each slot 101 position corresponds to a quantitative material slot 102, and the depth dimension and inner diameter dimension of each slot 101 are different.

[0064] The measuring tool 20 includes a plurality of measuring pieces 21. A measuring portion 211 is formed at one end of the measuring piece 21, and a holding portion 212 is protruded at the other end. The user can hold the holding portion 212 to facilitate moving the measuring piece 21. The shape of the measuring portion 211 is similar to the shape of the ear canal in the human ear. The shape of the measuring portion 211 is roughly a long cylinder. The volume of the measuring portion 211 of each measuring piece 21 is different. The slot 101 into which the measuring portion 211 with a larger volume can be inserted corresponds to the quantitative material slot 102 with a larger volume, such as Figure 1 , Figure 2 The specific embodiment shown in FIG. 1 has five measuring members 21 . The measuring portion 211 of each measuring member 21 has different specifications and sizes, that is, the length and outer diameter of the measuring portion 211 are different. Each measuring member 21 is placed in a corresponding one of the slots 101 .

[0065] See also Figure 1 and Figure 3 As shown, when the user selects and confirms one of the measuring pieces 21 that is close to the ear canal from among the multiple measuring pieces 21 of the measuring tool 20, the user can place the measuring pieces 21 with measuring parts 211 of different sizes into the ear canal of the ear for measurement one by one, select one of the measuring pieces 21 that matches the ear canal space, and place the slot 101 where the matching measuring pieces 21 are placed opposite to one of the quantitative material slots 102, so that the matching quantitative material slots 102 can be selected.

[0066] See also Figure 1 , Figure 4 and Figure 5As shown, the molding material 30 includes a packaging 300, a first material 31 and a second material 32, wherein the first material 31 and the second material 32 are separately packaged in the packaging 300, and a storage groove 103 is formed on the wall of the material 10, and the molding material 30 can be placed in the storage groove 103. The first material 31 and the second material 32 of the molding material 30 are raw materials for making earplugs. The user can put the first material 31 and the second material 32 into the quantitative material groove 102 that matches each other as mentioned above and fill them up, so that the amount of materials for making earplugs can be accurately measured. Since the first material 31 and the second material 32 are existing materials for making earplugs, such as polyvinylsiloxane (PVS), which is an addition reaction type silicone elastomer and a viscous liquid, after the first material 31 and the second material 32 are mixed, they will quickly harden into a rubber-like solid. Since its composition is not within the scope of the rights to be protected by the present invention, its material composition and the like will not be described in detail.

[0067] The present invention further includes a material picking member 40, which is a sheet body, and a material picking head 41 is formed protruding from the sheet body. A sheet groove 104 is formed inwardly on the wall surface of the material 10, and the material picking member 40 can be placed in the sheet groove 104. Figure 4 The material taking head 41 shown in the figure protrudes outward from the periphery of the sheet body, and can provide the user with a method of scooping out the first material 31 or the second material 32 located in the packaging 300, and placing and filling the quantitative material trough 102 that matches each other as described above. At this time, the amount of the mixed material 301 after the first material 31 and the second material 32 are mixed can be suitable for the size of the user's ear canal and the amount of material for making the earplug.

[0068] See also Figure 1 and Figure 6 As shown, the present invention may further include a marking member 50, the marking member 50 includes a left marking mold 51 and a right marking mold 52, and one or more containing grooves 105 are formed inwardly on the wall surface of the material 10. Figure 1 and Figure 6 The embodiment shown in the figure has two containing grooves 105, which can respectively provide a left marking mold 51 and a right marking mold 52 for storage. The surfaces of the left marking mold 51 and the right marking mold 52 can respectively have a marking symbol. The marking symbols of the left marking mold 51 and the right marking mold 52 can be lines or patterns, which can be used when the first material 31 and the second material 32 are mixed but have not yet hardened into a rubber-like solid. The lines or patterns of the left marking mold 51 or the right marking mold 52 can be printed on the earplug material to distinguish earplugs made in different ear canals, so that users can correctly distinguish and use the earplugs.

[0069] Furthermore, the present invention may further include a storage box 60 and a lubricant 70. A first groove 106 and a second groove 107 are formed inwardly on the side of the material 10. The first groove 106 can be used for storing the storage box 60. The storage box 60 is a box body that can be opened and closed, and can provide storage or removal of the earplugs after production. The second groove 107 can be used for storing the lubricant 70.

[0070] The earplug manufacturing method of the present invention is as follows Figure 1 , Figure 3 and Figure 8 As shown, the steps are as follows:

[0071] Measuring the size of the ear canal 1: The user places the measuring pieces 21 of different sizes in the measuring tool 20 into the ear canal of the user with their measuring parts 211, and measures the size of the ear canal with the measuring parts 211 of each measuring piece 21;

[0072] Select the corresponding quantitative material slot 2: After selecting the measuring piece 21 that can fit the user's ear canal more closely, such as Figure 4 As shown, the position of the slot 101 corresponding to the measuring piece 21 corresponds to a quantitative material slot 102 for making one of the earplugs;

[0073] Taking the molding material 3: taking out the first material 31 or the second material 32 in the package 300 and placing it into the quantitative material slot 102 matched with each other as described above and filling it up, at this time, the amount of the first material 31 and the second material 32 is suitable for the size of the user's ear canal and the amount of the earplug material;

[0074] To make the mixed material 4: take out the first material 31 or the second material 32 from the quantitative material tank 102 and press it into the mixed material 301;

[0075] The mixed material is shaped 5: the mixed material 301 is placed toward the ear canal of the user, such as Figure 5 As shown, and fit with the wall of the ear canal to be formed into the shape and size of the earplug;

[0076] Making finished earplugs 6: After the mixed material formed into the shape of earplugs solidifies, the finished earplugs are made.

[0077] In the earplug manufacturing method of the present invention, when the mixed material 301 is bonded to the wall of the ear canal to form a shape, Figure 6 and Figure 7 As shown, to make a left earplug L, the left marking mold 51 of the marking member 50 is selected, and the texture or pattern of the left marking mold 51 is embossed on the mixed material 301 of the earplug material, so that a specific texture or pattern can be formed to provide a left earplug that can be easily identified by the user as being for the left ear. In the same way, the right marking mold 52 can be used to make the right earplug;

[0078] like Figure 7 As shown, the material for making the earplug located in the ear canal is taken out from the ear canal after being solidified to make a finished left earplug L. The right earplug can be made in the same way.

[0079] The user can use the earplug making kit and earplug making method of the present invention to make earplugs of suitable sizes for users with different body shapes or ear canal sizes. When making the earplugs, the measuring pieces 21 of the measuring tool 20 can be used to measure the size of the user's ear canal, and the amount of the first material 31 and the second material 32 of the molding material 30 can be accurately taken out to achieve a customized earplug that matches the user's ear canal, which can improve the user experience and the comfort and convenience of wearing the earplugs. Since the left earplug and the right earplug suitable for the left ear canal or the right ear canal are both formed with identifiable lines or patterns, the user can use touch to quickly distinguish between the left earplug and the right earplug.

[0080] The above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been recorded as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents recorded above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
