For example, when an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

[0047] In addition, reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that the embodiments described herein are merely examples from a potentially infinite number of embodiments that serve the same or similar purpose or functions. Accordingly, the application should not be construed as being limited to the particular embodiments described in the specification.

[0048] The mobile phone waterproof bag provided by the embodiment of the application is mainly used for accommodating or placing a mobile phone (not shown in the figure) for use by a user when he is on water. It should be noted that the mobile phone waterproof bag is not limited to accommodating a mobile phone, and can also accommodate a smart watch or other electronic devices, which are not limited by the application.

[0049] As shown in Figures 1 to 2 The waterproof bag for mobile phone comprises a bag body 1 and an air-tight zipper 2. An accommodating space with an opening 11 is formed in the bag body 1. A user can put or take out a mobile phone into or from the accommodating space through the opening 11. The opening 11 is arranged at the top end of a sealing part 12 of the bag body 1 along the width direction of the bag body 1. The air-tight zipper 2 is arranged at the opening 11 to seal the bag body 1. The air-tight zipper 2 is arranged at the top end of the sealing part 12 and is flat when viewed from the front of the bag body 1 and is arc-shaped when viewed from the side of the bag body 1. The design can greatly reduce the size of the bag body 1, so that the user can conveniently carry or operate the mobile phone. In addition, as shown in Figure 1 The bag body 1 is further provided with a first transparent film 15 and a second transparent film 16. The first transparent film 15 is used for touch control of the screen of the mobile phone, and the second transparent film 16 is used for photographing with the camera of the mobile phone.

[0050] In the embodiment, the material of the bag body 1 is preferably TPU. The TPU material has the advantages of high strength, tear resistance, cold resistance, high temperature resistance, wear resistance, waterproofness, environmental protection, scratch resistance, smoothness and the like. On the other hand, the TPU material and the material of the air-tight zipper 2 can be better fused and welded, so as to improve the product quality.

[0051] It should be noted that the air-tight zipper 2 can also be a water-tight zipper. The air-tight zipper and the water-tight zipper have the same structure, the same principle and similar appearance. Only the sealing level is slightly different. As long as the waterproof sealing of the mobile phone waterproof bag can be ensured, the air-tight zipper 2 can be a type with teeth occlusion. The air-tight zipper 2 can also be a type without teeth. The air-tight zipper 2 can be a woven type. The air-tight zipper 2 can also be a plastic steel type. In short, as long as the zipper can prevent air or water, it can be used. As long as water cannot enter the bag after the zipper is closed, it can be used. The specific type of the air-tight zipper is not limited in the utility model, and the person skilled in the art can select it according to the actual situation.

[0052] It should be noted that the opening 11 is arranged along the width direction of the bag body 1. The direction in which the mobile phone is inserted or taken out of the accommodating cavity is perpendicular to the direction of the opening 11. It can also be understood that the long side of the mobile phone is parallel to the length of the bag body, and the short side of the mobile phone is parallel to the opening 11. The mobile phone is inserted into the accommodating cavity of the bag body 1 vertically.

[0053] In addition, as shown in Figure 12 The opening 11 can also be arranged along the length direction of the bag body 1. After being arranged, the bag body 1 is rectangular. The utility model does not limit this, and the person skilled in the art can select it according to the actual situation.

[0054] Further, as a specific implementation manner in some embodiments of the utility model, as shown in Figure 1 orFigure 2 As shown, the bag body 1 is divided into a sealing part 12 and a mobile phone placement part 13. With the front of the bag body 1 as the comparison direction, the width of the mobile phone placement part 13 is more than 6mm smaller than the width of the sealing part 12. When the width of the mobile phone placement part 13 is reduced to just enough to accommodate the width of a smartphone, the user can comfortably hold the waterproof bag to operate the smartphone screen. At the same time, the user can also easily operate and press the side buttons of the smartphone. In addition, the width that just accommodates a smartphone makes the bag smaller and more convenient to carry.

[0055] It should be noted that the width of the phone placement part 13 can be reduced to just accommodate a smartphone, but the sealing part 12 cannot be reduced to just accommodate the phone like the phone placement part 13. This is because the airtight zipper 2, in addition to the opening in the middle that needs to accommodate the smartphone, also includes the zipper pull and the welding positions on both sides of the zipper. The sealing part 12 must be wider than the width of the phone placement part 13. The width of the sealing part 12 is preferably between 130mm and 175mm, and the width of the phone placement part 13 is preferably between 100mm and 125mm.

[0056] In other embodiments, such as Figure 11 As shown, the width of the mobile phone placement part 13 can also be increased to be the same as the width of the sealing part 12, so that the bag body 1 is rectangular.

[0057] Alternatively, preferably, the airtight zipper 2 and the opening 11 are offset from the central axis of the width direction of the mobile phone placement part 13 in the opening direction of the airtight zipper 2, and the offset distance is 3mm to 20mm. After the offset setting, the zipper head will not interfere with the placement or removal of the mobile phone while ensuring that the width of the bag body 1 is minimized. Whether the offset setting is required is not limited in this utility model.

[0058] Furthermore, as a specific embodiment of some embodiments of this utility model, with the side of the bag body 1 as the comparison direction, the width of the sealing part 12 of the bag body 1 is greater than that of the mobile phone placement part 13. This is because, when viewed from the side of the bag body 1, the airtight zipper 2 is installed in the sealing part 12 in an arc-shaped bend. Since the airtight zipper 2 is made of TPU, which is elastic, the elasticity of the airtight zipper 2 after bending forcibly opens the sealing part 12, so the width of the sealing part 12 is greater than that of the mobile phone placement part 13.

[0059] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 7 to 10 As shown, Figure 7 It is a diagram of the shape of a whole piece of waterproof fabric. Figure 8 This is a diagram showing the shape of the entire waterproof fabric after the airtight zipper has been installed (181). Figure 9is a schematic diagram of the shape after the whole waterproof fabric is symmetrically bent 180 degrees, the bag body 1 is symmetrically bent 180 degrees by the whole waterproof fabric, and the three-direction 3-edge welding positions 17 of the bag body 1 are fully sealed and welded, it needs to be explained that, since the edge where the air-tight zipper 2 is installed naturally forms a sealing surface and does not need to be welded, only the three-direction 3-edge welding positions 17 need to be welded, and after welding, a fully-sealed containing cavity with an opening 11 is formed in the bag body 1 (not shown in the figure), and the design is simple to manufacture.

[0060] Of course, in other embodiments, the bag body 1 can also be manufactured by injection molding, and the utility model is not limited.

[0061] Further, as a specific embodiment of some embodiments of the utility model, as shown in Figure 2 , the bag body 1 is also provided with a sealing part fitting mechanism 7, since the air-tight zipper 2 is installed at the top end of the sealing part 12 in an arc-shaped bent shape, the air-tight zipper 2 has natural elasticity to forcibly open the bag opening, which causes the mobile phone screen to not be attached to the first transparent film 15, and the user's touch operation experience of the mobile phone screen is poor, so the fitting mechanism 7 is needed to attach the sealing part 12 to narrow it a little, and in this embodiment, the sealing part fitting welding groove 71 is preferably used to weld the two sides of the sealing part 12 together.

[0062] In other embodiments, the fitting mechanism 7 can also be used to set a magic tape at a position close to the air-tight zipper 2 inside the bag body 1 to narrow and fit the two sides of the sealing part 12 together,

[0063] In addition, a film can also be set at a position close to the air-tight zipper 2 inside the bag body 1, the film and the first transparent film 15 form a space, the user's mobile phone is placed in the space, and the film forcibly attaches the mobile phone screen and the first transparent film 15, which is convenient for the user to touch and operate the mobile phone.

[0064] In addition, as shown in Figure 1 , the bag body 1 is also provided with a hook hole 8, the user can connect the hook hole 8 and the hook of the hanging rope, so that the hanging rope is hung on the user's neck, the hook hole 8 can be set at the top end of the left and right sides of the sealing part 12 of the bag body 1, can also be set on the side of the bag body 1, and can also be set at other positions of the side of the bag body 1, and the utility model does not limit this, and the person skilled in the art can select according to the actual situation.

[0065] Further, as a specific embodiment of the mobile phone waterproof bag provided by the utility model, as shown in Figure 3 or Figure 4 , the mobile phone waterproof bag further comprises a buoyancy increasing assembly 3.

[0066] It can be understood that when the user accidentally drops the waterproof bag into water during work and play after putting the mobile phone or other electronic articles into the mobile phone containing cavity of the bag body 1 of the mobile phone waterproof bag, the waterproof bag can float on the water surface due to the buoyancy of the buoyancy assembly 3, so as to avoid the loss of valuable articles of the user.

[0067] It should be noted that the shape of the buoyancy assembly 3 can be rectangular, square, trapezoidal, hexagonal, pentagonal, triangular, circular, hexagonal, and other various shapes, as long as the buoyancy assembly 3 can function as a buoyancy, and the present application does not limit this, and the person skilled in the art can select according to the actual situation.

[0068] As shown in the accompanying drawings, Figure 3 The buoyancy assembly 3 is a square-shaped capsule 31, and the square-shaped buoyancy object 32 is inside the square-shaped capsule 31.

[0069] In this embodiment, the square-shaped capsule 31 is installed on the outer peripheral wall of the bag body 1 and forms a second containing cavity (not shown in the figure) together with the bag body 1, and the square-shaped buoyancy object 32 is placed in the second containing cavity.

[0070] In this embodiment, preferably, the square-shaped buoyancy object 32 is EPE pearl wool, and it should be noted that the square-shaped buoyancy object 32 can also be gas or some other soft material, and placing the square-shaped buoyancy object 32 can generate higher super-large buoyancy, so that the waterproof bag containing a large mobile phone can float on the water surface.

[0071] In addition, as shown in the accompanying drawings, Figure 4 The buoyancy assembly 3 can also adopt the structure of a peripheral circular air bag 33, and the circular air bag 33 is simple to manufacture.

[0072] Further, as a specific embodiment of the mobile phone waterproof bag provided by the present application, as shown in the accompanying drawings, Figure 1 Or Figure 6 It also includes an anti-slip mechanism 4, which is arranged on one side of the airtight zipper 2 of the bag body 1.

[0073] It should be noted that since the airtight zipper mobile phone waterproof bag needs to ensure the highest level of airtightness, the airtight zipper 2 must be designed and manufactured to be slightly tight to achieve the sealing effect of the airtight level, which makes it difficult for the user to open and close the zipper. The normal opening and closing of the airtight zipper 2 has a pulling force of 1.5 kg, but in actual use, due to the lubrication of water and sweat, the user holds the pull plate 21 of the airtight zipper 2 with one hand, and the fingers of the other hand pinch the edge of the bag body 1, and the two are pulled in opposite directions. Under the condition of water and sweat, this can cause the fingers pinching the edge of the bag body 1 to slip seriously, resulting in a situation where there is no place to exert force, leading to the user's inability to open or close the airtight zipper.

[0074] The anti-skid mechanism 4 can be matched with the air-tight zipper 2, one hand of a user holds the pull plate 21 of the air-tight zipper 2, and the fingers of the other hand pinch or hook the anti-skid mechanism 4 on the bag body 1, and the two are pulled in opposite directions, so that the fingers of the user do not slip on the edge of the bag body 1 even in the case that the bag body 1 is lubricated by water and sweat, and therefore the anti-skid mechanism 4 and the pull plate 21 can be matched to enable the user to easily open or close the air-tight zipper 2.

[0075] It should be noted that the anti-skid mechanism 4 can be Figure 1 the anti-skid block 41 shown in the figure, or Figure 6 the anti-skid ring 42 shown in the figure, the anti-skid ring 42 is in the shape of a hollow ring, and the anti-skid ring 42 can be in various shapes such as D-shaped, O-shaped, C-shaped, and hook-shaped, the anti-skid ring 42 has the function that the fingers of the user can be passed through the ring body, the user can more stably hook the anti-skid ring 42 with the fingers, one hand of the user holds the pull plate 21, and the fingers of the other hand hook the anti-skid ring 42 to apply opposite forces to open or close the air-tight zipper, or one hand of the user holds the pull plate 21, and the fingers of the other hand pinch the anti-skid block 41 to apply opposite forces to achieve the same effect.

[0076] Further, as a specific embodiment of the mobile phone waterproof bag provided by the utility model, as Figure 5 shown in the figure, the utility model further comprises a transparent convex body 5, the transparent convex body 5 is arranged on the bag body 1, at least one single transparent convex block 51 is formed in the transparent convex body 5, the single transparent convex block 51 is in the shape of an arch along the cross section in the height direction, so that the user can touch and operate the mobile phone screen through the single transparent convex block 51 under water, the material of the transparent convex body 5 is a transparent film, the transparent convex body 5 can be arranged outside the bag body 1, and the transparent convex body 5 can also be arranged inside the bag body 1.

[0077] It can be understood that the existing waterproof bag is used under water, and because of the water pressure under water, the water pressure tightly adheres the first transparent film 15 of the bag body 1 to the mobile phone screen, and the water and the mobile phone screen are naturally adhered together, at this time, the user cannot transmit the electric charge to the screen of the mobile phone, leading to the failure of the touch of the screen of the mobile phone, when the transparent convex body 5 provided by the utility model is used under water, the user clicks and presses the single transparent convex block 51 through the fingers, and the single transparent convex block 51 is used to isolate the conductivity of water, so as to transmit the electric charge of the fingers to the screen of the mobile phone, thereby realizing the touch of the screen of the mobile phone under water and improving the user experience.

[0078] In addition, as Figure 5As shown in the right view, the single transparent bump 51 has an arch shape 52 in the cross section along its height direction (specifically, high in the middle and low at the periphery). It should be noted that the arch shape 52 can increase the air volume and height inside the transparent bump 51, and can more sensitively touch the mobile phone screen, thereby improving the user experience. In addition, the arch shape 52 can resist the water pressure received by the transparent bump 51, thereby reducing the risk of deformation or rupture. In this way, the mobile phone can be protected from water pressure, thereby prolonging its service life.

[0079] Of course, in other embodiments, the cross section of the transparent bump 51 along its height direction can also be a part of the middle area as a plane and the left and right sides as a circular arc, as long as it is similar to the arch shape 52. The present application does not limit this, and those skilled in the art can choose according to the actual situation.

[0080] In addition, preferably, when the number of transparent bumps 51 is 1, the height is preferably 13 mm, when the number is 2, the height is preferably 10 mm, when the number is 3, the height is preferably 8.5 mm, when the number is 4, the height is preferably 8 mm, when the number is 5, the height is preferably 7.5 mm, when the number is 6, the height is preferably 7 mm, when the number is 7, the height is preferably 6.5 mm, and when the number is 8, the height is preferably 6 mm.

[0081] Further, as a specific implementation of some embodiments of the present application, Figure 1 As shown, the edge wrapping strip 6 is arranged at the convex corner of the side edge of the bag body 1. The edge wrapping strip 6 arranged at the convex corner of the side edge can protect the user's skin from being scratched.

[0082] In addition, the edge wrapping strip 6 can also be a full-circle edge wrapping (not shown in the figure). The full-circle edge wrapping is arranged at the periphery of the side edge of the bag body 1.

[0083] It should be noted that the full-circle edge wrapping can protect the periphery of the side edge of the bag body 1, but the full-circle edge wrapping has a high manufacturing cost. In addition, it should be noted that as long as the edge wrapping occupies most of the positions of the periphery of the side edge, it can be considered as full-circle edge wrapping. Therefore, the full-circle edge wrapping can also be understood as the position of the edge wrapping occupying most of the positions of the side edge of the bag body 1. The material of the edge wrapping strip 6 is preferably TPU, which can be better welded with the bag body 1. In addition, other materials can also be used, as long as the material can be connected with the bag body 1 and has a soft quality. The present application does not limit the specific material used.

[0084] In addition, the edge wrapping mechanism 6 can also use a line-woven edge wrapping strip, that is, use a sewing machine needle and thread to wrap the edge. The present application does not limit this, and those skilled in the art can choose according to the actual situation.

[0085] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
