Description

Technical Field

[0001] This utility model relates to the field of waterproof bag technology, and in particular to a waterproof bag for mobile devices. Background Technology

[0002] With the continuous enrichment of smartphone functions, mobile phones have become an indispensable device in people's daily lives. To meet the needs of using mobile phones in aquatic environments, waterproof mobile phone cases have become a common accessory, widely used to allow users to carry their phones in places such as beaches, swimming pools, water parks, lakes, and hot springs, and to perform operations such as communication, taking pictures, listening to music, and watching videos.

[0003] Existing waterproof phone cases typically provide basic waterproof protection for phones through seals, preventing damage from water ingress to some extent. However, most of these cases only offer a simple waterproof seal and have a relatively rigid design. When a waterproof case is accidentally dropped into water, it often sinks to the bottom due to insufficient buoyancy, making it difficult for users to retrieve, and potentially leading to the loss of mobile devices and personal belongings.

[0004] Therefore, a waterproof bag for mobile devices is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a waterproof bag for mobile devices, which aims to solve the problem that existing waterproof bags for mobile phones only have waterproof function, are single in function, and have insufficient buoyancy.

[0006] To achieve the above-mentioned utility model objectives, this utility model proposes a waterproof bag for mobile devices, including a waterproof bag body and a sealing member disposed inside the bag opening of the waterproof bag body. The sealing member is used to seal the waterproof bag body. The internal space of the waterproof bag body forms a receiving cavity for placing the mobile device. The waterproof bag body expands outward to form an air cavity, and the height of the air cavity is greater than that of the mobile device.

[0007] The air cavity is disposed along the edge of the receiving cavity, and the air cavity is not connected to the receiving cavity.

[0008] Furthermore, the distance between the air cavity and the surface of the waterproof bag is greater than the height of the mobile device.

[0009] Furthermore, the air cavity forms an obtuse angle with the surface of the waterproof bag.

[0010] Furthermore, the inner wall of the receiving cavity is formed with a contoured groove that matches the shape of the mobile device, for limiting the position of the mobile device.

[0011] Furthermore, a transition section is formed at the corner of the air cavity for buffering.

[0012] Furthermore, the distance between the edge of the air cavity and the edge of the waterproof bag body is less than 5mm.

[0013] Furthermore, the number of the seals includes at least two.

[0014] Furthermore, the waterproof bag body is made of a transparent flexible film.

[0015] Furthermore, the waterproof bag body is provided with a hanging loop for connecting to wearable accessories.

[0016] Beneficial effects:

[0017] This utility model discloses a waterproof bag for mobile devices, comprising a waterproof bag body and a sealing element disposed inside the bag opening of the waterproof bag body. The sealing element seals the waterproof bag body, and the internal space of the waterproof bag body forms a receiving cavity for placing the mobile device. The waterproof bag body expands outward to form an air cavity, the height of which is greater than that of the mobile device. The air cavity is disposed along the edge of the receiving cavity and is not connected to the receiving cavity. This utility model, by setting a sealing element on the waterproof bag body and forming an outwardly expanding air cavity, ensures not only the waterproof sealing of the bag body but also allows the waterproof bag to remain buoyant in water, preventing the mobile device from sinking. Simultaneously, the air cavity also acts as a buffer layer, effectively absorbing external impact forces and improving drop resistance, thereby significantly enhancing the safety of mobile devices during water activities and daily use.

[0030] Reference Figure 1 and Figure 2This utility model discloses a waterproof bag for mobile devices, including a waterproof bag body 100 and a sealing member 200 disposed inside the bag opening of the waterproof bag body 100. The sealing member 200 is used to seal the waterproof bag body 100. The internal space of the waterproof bag body 100 forms a receiving cavity 300 for placing the mobile device. The waterproof bag body 100 expands outward to form an air cavity 400. The height of the air cavity 400 is greater than that of the mobile device.

[0031] The air cavity 400 is disposed along the edge of the receiving cavity 300, and the air cavity 400 is not in communication with the receiving cavity 300;

[0032] The distance between the air cavity 400 and the surface of the waterproof bag 100 is greater than the height of the mobile device;

[0033] The air cavity 400 forms an obtuse angle with the surface of the waterproof bag body 100.

[0034] The inner wall of the receiving cavity 300 is formed with a contoured groove that matches the shape of the mobile device, which is used to limit the position of the mobile device.

[0035] A transition section is formed at the corner of the air cavity 400 for buffering;

[0036] The distance between the edge of the air cavity 400 and the edge of the waterproof bag body 100 is less than 5mm;

[0037] The number of the seals 200 includes at least two;

[0038] The waterproof bag body 100 is made of a transparent flexible film.

[0039] The waterproof bag body 100 is provided with a hanging loop hole for connecting to wearable accessories.

[0040] This utility model's waterproof bag for mobile devices includes a waterproof bag body 100, a bag opening seal 200, and a receiving cavity 300 and an air cavity 400. When the mobile device is placed into the receiving cavity 300 of the waterproof bag body 100, the user seals the bag opening with the seal 200, isolating the receiving cavity 300 from the outside world and preventing water from entering. The waterproof bag body 100 expands outward to form the air cavity 400. When the waterproof bag body 100 is placed in water, the air cavity 400 provides buoyancy due to the enclosed air inside, allowing the waterproof bag to float on the water surface. When the waterproof bag is subjected to external impact or falls, the air cavity can also act as a buffer to absorb energy, reducing the direct impact on the mobile device. Since the inner wall of the receiving cavity 300 has a contoured groove that matches the shape of the mobile device, it can be positioned when the mobile device is placed inside, thereby improving the convenience of loading and unloading and ensuring stability during use.

[0041] In this embodiment, the air cavity 400 formed by the outward expansion of the waterproof bag body 100 forms an obtuse angle α with the surface of the waterproof bag body 100. Specifically, the angle α is 135 degrees. When the mobile device is placed in the receiving cavity 300 of the waterproof bag and sealed, since the obtuse angle is formed between the air cavity 400 and the surface of the waterproof bag body 100, this structure can disperse the impact force when subjected to external force, reducing the direct transmission of external force to the mobile device in the receiving cavity 300. In addition, in a water environment, the inclined angle makes the air cavity 400 have an outward expansion shape, which helps to improve the buoyancy stability of the air cavity 400 and ensures that the bag maintains a good posture when floating, reducing the possibility of tumbling.

[0042] This invention, based on the waterproof bag body 100, forms an independent air cavity 400 structure by expanding outwards. The air cavity 400 not only ensures buoyancy and cushioning but also cleverly improves the touch experience. Traditional waterproof bags are usually single-layer flexible films that are tightly attached to the screen of mobile devices. When users operate in water, the screen often experiences decreased sensitivity or accidental touches due to the tightness of the bag and the water pressure. This solution utilizes the air cavity 400 to form an air buffer layer between the bag surface and the receiving cavity 300, which is equivalent to setting an intermediate transition medium between the device screen and the external water pressure. This allows the user's touch pressure to be transmitted to the screen more evenly and effectively. Through this design, the waterproof bag not only achieves waterproof, drop-proof, and buoyancy protection functions but also takes into account the convenience and sensitivity of underwater and above-water operation.

[0043] Once the mobile device is placed in the receiving cavity 300 and sealed, during use, the touch pressure applied by the user's fingertip first acts on the flexible film of the outer layer of the waterproof bag 100. Due to the presence of the air cavity 400, this pressure is not immediately offset by water pressure, but is transmitted to the device screen through gas compression and film elasticity. Compared to the traditional tightly bonded single-layer structure, this "gas intermediary layer" avoids water pressure interference with the touch signal, making touch operation closer to the bare device state. Especially in underwater environments, where the external hydrostatic pressure is high, the air inside the air cavity 400 can form a stable back pressure, thereby maintaining an appropriate gap between the bag and the device screen, preventing excessive film adhesion that could cause operational lag or screen malfunction. Therefore, users can achieve sensitive and smooth touch operation both on and underwater.

[0044] This design incorporates a transition section 500 at the corner of the air chamber 400. Through process design, the corner is rounded, which improves the overall appearance of the bag and enhances cushioning protection in critical areas. It is particularly suitable for protecting mobile equipment in the event of a drop or collision. When the mobile equipment is placed inside the receiving cavity 300 and sealed, the transition section 500 at the corner of the air chamber 400 allows the impact force to be dispersed along the rounded transition surface when the waterproof bag is dropped or subjected to lateral impact, preventing it from concentrating at a single point. Simultaneously, the rounded transition area deforms under stress, acting as a cushioning pad to absorb some of the impact energy, thereby reducing the risk of direct damage to the internal mobile equipment.

[0045] Furthermore, the waterproof bag body 100 of this solution is formed by high-frequency hot pressing and shaping process, and under the secondary pressing of the mold, the waterproof bag body 100 forms two independent cavities, thus constituting independent sealed air cavities. Each air cavity 400 has a transition part 500 at its corner. The four R corners play a buffering and protective role when the waterproof bag body 100 is hit or dropped, effectively dispersing the impact force and avoiding damage to the internal moving parts. Furthermore, in this embodiment, the distance h between the edge of the air cavity 400 and the edge of the waterproof bag body 100 is less than 5mm. This design makes the lever arm of the internal pressure of the air cavity 400 acting on the sealing edge shorter, reducing the tendency of the sealing edge to peel or tear. At the same time, the high-frequency weld is located on the outside of the air cavity 400, and the expansion of the air cavity 400 is less likely to pull the weld and cause local tearing, thus improving durability.

[0046] Traditional waterproof bags for mobile devices are mostly single-layer film structures, providing only basic waterproofing. They cannot prevent damage from drops and are prone to sinking in water, making them difficult to retrieve. This solution enhances sealing reliability and ensures waterproof performance by incorporating at least two sealing elements 200 at the opening of the waterproof bag body 100. The waterproof bag body 100 uses a transparent, flexible film material, allowing users to perform touch operations without removing the phone. The waterproof bag body 100 expands outward to form an air cavity 400, continuously distributed along the edge of the bag. Furthermore, the thickness of the waterproof bag body 100 is designed to be greater than that of traditional waterproof bags, thus providing both buoyancy and cushioning functions. A lanyard hole is added to the surface of the bag, allowing it to be connected to accessories for easy carrying. A contoured groove conforming to the shape of the phone is formed on the inner wall of the receiving cavity 300 through a pressing process, enabling quick and smooth insertion and removal of the phone and maintaining stability during use. Through the above design, this invention not only improves the protective performance of the waterproof bag but also enhances the user experience.

[0047] In summary, this design offers several advantages. First, it provides strong waterproofing performance. The bag opening features at least two seals 200, which significantly improves sealing strength and reduces the risk of leakage compared to a single seal. Second, it has a buoyancy function. The waterproof bag body 100 expands outward to form an air chamber 400, providing sufficient buoyancy in water to allow the bag to float automatically and prevent the phone from sinking. Third, it offers drop protection. The air chamber also acts as a buffer layer, and the increased thickness of the waterproof bag body 100 absorbs energy when the phone is dropped or subjected to external impact, reducing the risk of damage. Through these design features, this solution maintains basic waterproofing while also providing buoyancy, drop protection, ease of use, and portability. Compared to traditional waterproof bags for mobile devices that only offer waterproofing, this solution significantly improves buoyancy, drop protection, and ease of use, better meeting the actual needs of users.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
