Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof sports earmuff technology, and in particular to a waterproof and sweat-proof sports earmuff. Background Technology
[0002] Sports earbuds are headphone accessories specifically designed for sports, made with sweat-resistant silicone or breathable memory foam, offering both comfort and a secure fit. Their unique structure (such as shark fins and ear hooks) effectively prevents them from slipping off during exercise, and their IPX4 or higher waterproof rating resists sweat. Some products support an ambient sound mode for enhanced outdoor safety. Their lightweight design (approximately 10 grams) reduces wearing burden, making them suitable for running, fitness, and other similar activities. It is recommended to choose the correct size based on your ear shape and perform regular cleaning and maintenance to extend their lifespan.
[0003] In existing technology, sports foam is inserted into the ear canal after being fitted onto the outside of the earphone. Sweat can seep into the interior of the sports foam body, affecting the use of the device. However, traditional ear foam is not waterproof or sweatproof, making it easy for moisture to seep in and affecting the performance. Utility Model Content
[0004] The purpose of this utility model is to provide a waterproof and sweatproof sports ear cotton, which solves the problem that when sports sponge is inserted into the ear canal after being put on the outside of the earphone, sweat will enter the interior of the sports ear cotton body, thus affecting the use of the device. However, traditional ear cotton is not easy to waterproof and sweatproof, and moisture is easy to seep in.
[0005] To achieve the above objectives, a waterproof and sweat-proof sports earmuff is provided, comprising: a sports earmuff body, an inner lining layer fixedly connected to the inner side of the sports earmuff body, a mating groove provided between the sports earmuff body and the inner lining layer, a sponge layer inserted into the mating groove, and a rubber sheath layer fixedly connected to the inner side wall of the sponge layer.
[0006] As a preferred embodiment of the present invention, the main body of the sports ear cotton and the sponge layer are arranged in a conical shape.
[0007] As a preferred embodiment of the present invention, the inner wall of the lining layer is fixedly connected with rubber protrusions, and the rubber protrusions and the sponge layer are engaged.
[0008] As a preferred embodiment of the present invention, the main body of the sports ear cotton is made of cotton material.
[0009] As a preferred embodiment of the present invention, the sponge layer is made of absorbent sponge material.
[0010] The above-mentioned solution has the following beneficial effects:
[0011] This utility model comprises: an ear cotton body, a sponge layer, and a rubber sleeve layer. The entire sports ear cotton body is fitted over the outside of the sports headphones. When sweat occurs during exercise, it can be absorbed by the sports ear cotton body and the sponge layer. After absorption, the rubber material of the rubber sleeve layer acts as a barrier to prevent moisture from entering the interior of the sports ear cotton body.
[0012] This invention features a sponge layer, a rubber sleeve layer, and rubber protrusions. The sponge layer and rubber sleeve layer are fitted between the main body of the sports earbud and the inner lining layer. The rubber protrusions then provide rubber contact for fixation. The entire sports earbud can then be fitted over the outside of the sports headphones. When there is excessive sweating after use, the sponge layer can be removed for replacement, facilitating the absorption of sweat and effectively providing waterproofing and sweatproofing for the inside of the sports earbud.
[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments;

[0018] Legend:
[0019] The components include: 1. main body of sports ear cotton; 2. inner lining layer; 3. mating groove; 4. sponge layer; 5. rubber sheath layer; and 6. rubber protrusions. Detailed Implementation
[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0021] Reference Figure 1-3This utility model provides a waterproof and sweatproof sports earmuff, comprising: a sports earmuff body 1, an inner lining layer 2 fixedly connected to the inner side of the sports earmuff body 1, a mating groove 3 between the sports earmuff body 1 and the inner lining layer 2, a sponge layer 4 inserted into the inside of the mating groove 3, and a rubber sleeve layer 5 fitted between the sports earmuff body 1 and the inner lining layer 2, thus covering the entire sports earmuff body 1 on the outside of a sports earphone. During exercise, sweat can be absorbed through the sports earmuff body 1 and the sponge layer 4. The inner wall of the sponge layer 4 is fixedly connected to the rubber sleeve layer 5, which absorbs sweat through the sports earmuff body 1 and the sponge layer 4. After absorption, the rubber material of the rubber sleeve layer 5 acts as a barrier to prevent moisture from entering the interior of the sports earmuff body 1.
[0022] The main body 1 and the sponge layer 4 of the sports ear cotton are tapered. The inner wall of the inner lining layer 2 is fixedly connected with rubber protrusions 6. The rubber protrusions 6 provide rubber contact and fixation. The rubber protrusions 6 and the sponge layer 4 are snapped together. The main body 1 of the sports ear cotton is made of cotton material, and the sponge layer 4 is made of absorbent sponge material. When there is a lot of sweat after use, the sponge layer 4 can be removed for replacement. This facilitates the absorption of sweat and allows for easy replacement, effectively waterproofing and sweatproofing the inside of the main body 1 of the sports ear cotton.
[0023] Working principle: During use, the sponge layer 4 and the rubber sleeve layer 5 are placed between the main body 1 and the inner lining layer 2 of the sports earbud. The rubber protrusions 6 then provide rubber contact for fixation. The main body 1 of the sports earbud can then be placed over the outside of the sports earphone. When sweat occurs during exercise, it is absorbed by the main body 1 and the sponge layer 4. After absorption, the rubber material of the rubber sleeve layer 5 acts as a barrier to prevent moisture from entering the interior of the main body 1 of the sports earbud. When there is a lot of sweat after use, the sponge layer 4 can be removed for replacement. This allows for easy replacement after the sweat has been absorbed, effectively waterproofing and sweatproofing the interior of the main body 1 of the sports earbud.
[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
