Of course, in other embodiments, the cell phone waterproof bag can also be used for storing or placing electronic watches, cameras, and other items that are afraid of water, and the present application does not limit this.

FIGS. 1 to 4 show a first preferred embodiment of the present application, a cell phone waterproof pouch comprising a pouch body 1, the pouch body 1 is divided into an upper wide portion 11 and a lower narrow portion 12, the lower narrow portion 12 having a width dimension that is smaller than the width dimension of the upper wide portion 11.

As shown in FIG. 3, bag body 1 comprises a first bag body portion 14 and a second bag body portion 15 stacked and welded together.

As shown in FIGS. 1 to 4, the width dimension of the lower narrow portion 12 is smaller than the width dimension of the upper wide portion 11, and the width dimension refers to the direction of the width of the bag body 1 as a contrasting direction, preferably less than 15 mm or more; when the width of the lower narrow portion 12 is reduced to exactly accommodate the width of one smartphone users can comfortably hold the waterproof bag to operate the smartphone screen, and also it is convenient for the users to operate pressing the Smartphone side buttons, in addition, just to accommodate the width of a smartphone will make the bag body 1 smaller, more convenient to carry.

It should be noted that the width of the lower narrow portion 12 can be reduced to just accommodate a smartphone, but the upper wide portion 11 cannot be reduced in width to just accommodate a cell phone as well as lower narrow portion 12. This is because the airtight zipper 2 includes slider 22 of the airtight zipper 2 and the welding position of the two sides of the airtight zipper 2 in addition to the opening in the middle which is needed to accommodate a smartphone, and as a result, the upper wide portion 11 needs to be 15 mm or larger in width than the lower narrow portion 12. the width needs to be greater than the width of the lower narrow portion 12 by more than 15 mm.

In other embodiments, the upper wide portion 11 and the lower narrow portion 12 may also be the same size, with bag 1 having an overall rectangular profile.

In this embodiment, it is preferred that the bag body 1 is made of TPU material, and the TPU material has the advantages of high strength, abrasion resistance, waterproof, environmentally friendly, smooth, etc. Compared to the existing cell phone waterproof bag, the TPU cell phone waterproof bag is stronger and has better abrasion resistance, and it can effectively avoid the problem that the bag body 1 is damaged due to water ingress to the cell phone because of tearing or puncturing.

In other embodiments, the bag body 1 may also be a waterproof fabric of other materials, as long as the material is waterproof.

As shown in FIG. 1, FIG. 3, and FIG. 4, bag 1 is provided with a holding cavity having an opening 13, the opening 13 being disposed along the width of bag 1 at the upper wide portion 11.

The cell phone waterproof bag of this embodiment sets the opening 13 along the width direction of the bag body 1, and the opening 13 and the lower narrow portion 12 are non-interfering after the setup, which is convenient for the user to operate the cell phone, of course, in other embodiments, the opening 13 can be set up along the length direction of the bag body 1 as long as it can ensure the sealing of the cell phone waterproof bag.

As shown in FIG. 1, the airtight zipper 2 is mounted on the opening 13 of the bag body 1 for sealing the bag body 1. Specifically, when the cell phone is placed in the holding space, the user closes the opening 13 through the airtight zipper 2 to ensure that the waterproof bag for the cell phone is in a sealed state, avoiding the entry of external liquids that may cause damage to the cell phone; and when the user needs to remove the cell phone, the user opens the opening 13 again through the airtight zipper 2 When the user needs to take out the cell phone, the user then opens the opening 13 through the airtight zipper 2 to remove the cell phone from the holding space.

In this embodiment, it is preferred to use the airtight zipper 2, airtight zipper 2 has a high waterproof airtightness, and the airtight zipper 2 can be completely sealed, so that the liquid can not enter into the holding space of the pouch body 1, so as to further improve the scaling effect of the waterproof pouch for the cell phone.

In other embodiments, the airtight zipper 2 can also be a watertight zipper, it should be noted that the airtight zipper 2 and the watertight zipper have the same structure, the same principle, and a similar shape, only the sealing level has a slight difference, as long as it can ensure the waterproof sealing of the waterproof bag of the cell phone; in addition, the type of the airtight zipper 2 can be used in the first category of adhesive teeth-type airtight waterproof zippers, and also can be used in the second category of braid-type The type of airtight waterproof zipper2 can adopt the first type of rubber teeth type airtight waterproof zipper, can also adopt the second type of braided type airtight waterproof zipper, can also adopt the third type of convex and concave airtight waterproof zipper, as long as the waterproof or airproof airtight waterproof zipper can be used.

As shown in FIGS. 1 to 6, the cell phone waterproof bag further comprises a buoyancy enhancement assembly 3, the buoyancy enhancement assembly 3 is mounted on an outer peripheral wall of the bag body 1 for providing buoyancy to the cell phone waterproof bag 1, so that the cell phone waterproof bag 1 and the cell phone mounted inside the cell phone waterproof bag 1 are able to float in water.

In this embodiment, the buoyancy-enhancing component 3 is a transparent membrane body 31, the transparent membrane body 31 is disposed on an outer wall of the bag body 1, and at least one transparent air compartment 311 is formed within the transparent membrane body 31, and the transparent air compartment 311 is internally filled with air, which can provide buoyancy to the waterproof bag for the cell phone.

In another optional embodiment, the transparent film body 31 may also be provided inside the bag body 1. The transparent film body 31 provided on the inside of the bag body 1 has the same role and function as provided on the outside of the bag body 1.

In addition, the transparent membrane body 31 also has the function of isolating the conductivity of water, and the user can squeeze the transparent air compartment 311 by finger touch underwater to transfer the finger charge to the screen of the cellular phone, so as to realize the underwater touch control, and to be able to operate the cellular phone by touch through the transparent air compartment 311 underwater.

In this embodiment, as shown in FIGS. 5 and 6, the transparent air compartment 311 has an arch-shaped cross-section (specifically high in the center and low around the perimeter) along its height direction. It should be noted that the arch shape can resist the high water pressure of deep water, thereby reducing the risk of deformation or rupture thereof, and can also make the transparent air compartment 311 more sensitive to underwater touch screen operation.

Of course, in other embodiments, the cross-section of the transparent air compartment 311 along its height direction may also be planar in the middle portion of the area and surrounded by a large circular arc. It may also be convex, and may have other suitable shapes.

Further, when the number of transparent air compartments 311 is set from 1 to 4, the height of each transparent air compartment 311 (specifically the height of the highest point of the transparent air compartment 311) is 4 mm-20 mm. Specifically, when the number of transparent air compartments 311 is set to 1, preferably, the height of a single transparent air compartment 311 is 12 mm. When the number of transparent air compartments 311 is set to 2, preferably, the height of a single transparent air compartment 311 is 9 mm. When the number of transparent air compartments 311 is set to 3, preferably, the height of a single transparent air compartment 311 is 8.5 mm. When the number of transparent air compartments 311 is set to 4, preferably, the height of a single transparent air compartment 311 is 8 mm.

This not only enables the transparent air compartment 311 to be more aesthetically pleasing and taller, improving the tactile sensation of the user pressing the transparent molding but also ensures that the user is more responsive to operating the cell phone underwater using underwater. In addition, the taller transparent air compartment 311 can also provide greater buoyancy, allowing the cell phone to float on the water surface.

In another optional embodiment, when the number of transparent air compartments 311 is set from 5 to 8, the height of each transparent air compartment 311 is 3 mm-13 mm. specifically, when the number of transparent air compartments 311 is set to 5, preferably, the height of the transparent air compartments 311 is 7.5 mm. when the number of transparent air compartments 311 is set to 6, preferably, the height of the transparent air compartments 311 is 7 mm. Preferably, when the number of transparent air compartments 311 is set to 7, the height of the transparent air compartments 311 is 6.5 mm. preferably, when the number of transparent air compartments 311 is set to 8, the height of the transparent air compartments 311 is 6 mm.

It is to be noted that adopting a layout of 5 to 8 transparent air compartments 311 can, on the one hand, reduce the imprints between adjacent transparent air compartments 311 so as to make the user's touch operation of the cell phone underwater smoother; and on the other hand, due to the increase in the number of transparent air compartments 311, it can make the transparent air compartments 311 more taut to achieve a better transparent air compartments 311 touch and press rebound effect to improve the user's sense of experience.

In yet another optional embodiment, where the number of transparent air compartments 311 is 8 or more, the height of the transparent air compartments 311 is 1 mm-10 mm.

It should be noted that due to an increase in the number of transparent air compartments 311, there will be a disproportionate ratio between the length and width dimensions and the height dimensions of the individual transparent air compartments 311, resulting in the finger pressing on the transparent air compartments 311 not being able to press down, resulting in an inability to touch sensitively, so the transparent air compartments 311 will need to be lowered in height to be able to touch and use with an increase in the number of transparent air compartments 311 thereof.

Preferably, in this embodiment, the number of transparent air compartments 311 is 2, and the height of the 2 transparent air compartments 311 is preferably 9 mm.

In other embodiments, the cross-section of the transparent air compartment 311 along its length and width direction may be in the shape of a square, a rectangle, a triangle, etc., and the arrangement of the plurality of transparent air compartments 311 may be in the shape of a rectangular arrangement, a diagonal arrangement, or any arrangement, etc.

Exemplarily, when the airtight zipper 2 needs to be opened, the user holds the pull tag 21 with one hand hooks the pull ring 41 with the fingers of the other hand, and applies force on the pull tag 21 and the pull ring 41 to open the airtight zipper 2; conversely, applying a force in the opposite direction of the direction described above closes the airtight zipper 2.

Further, as shown in FIGS. 1 and 3, the pull ring 41 is provided on the side of the bag body 1 back from the airtight zipper 2.

Preferably, the pull ring 41 is provided on the side of the bag body 1 backing away from the airtight zipper 2 can avoid interfering with the collision of the pull tag 21 and the pull ring 41 when they are operated.

In another embodiment, the pull loop 41 may be provided on the same side as the airtight zipper 2 or on the opposite side of the airtight zipper 2. The pull loop 41 may also be provided on the side of the pouch 1.

In this embodiment, the number of pull loops 41 is two, and the two pull loops 41 are symmetrically disposed along the center axis of the pouch 1 so that the user can easily hold the two pull loops 41 to open (or close) the waterproof pouch for the cell phone.

The present application is preferably provided with two pull rings 41, one pull ring 41 cooperating to open the airtight zipper 2, and the other pull ring 41 cooperating to close the airtight zipper 2, so that when it is necessary to open (or close) the airtight zipper 2, the user only needs to hook the fingers of one hand on the pull ring 41, and pull the pull tab 21 of the airtight zipper 2 with the other hand, so that the airtight zipper 2 can be easily opened (or closed) to place or remove the cell phone.

Alternatively, the lanyard sling 5 can be integral with the bag body 1, a long section of convex shape can be provided along one side of the bag body 1, a through-hole can be provided in the convex shape, and an external hook can be passed directly through this through-hole to achieve the same effect as the lanyard sling 5, and the convex shape can be provided in one or two pieces.

FIGS. 7 to 9 show a second preferred embodiment of the present application, a waterproof bag for a cellular phone, comprising a bag body 1, the bag body 1 divided into an upper wide portion 11 and a lower narrow portion 12, with the width direction of the bag body 1 as a contrasting direction, the width dimension of the lower narrow portion 12 being smaller than the width dimension of the upper wide portion 11, the bag body 1 being provided with a first holding chamber having an opening 13, the opening 13 being disposed in a width direction along the width direction of the bag body 1 provided at the upper wide portion 11; further comprising an airtight zipper 2, the airtight zipper 2 being mounted at the opening 13 along the width direction of the bag body 1; further comprising a buoyancy enhancement assembly 3, the buoyancy enhancement assembly 3 being an airbag 32, the airbag 32 being mounted on an outer peripheral wall of the bag body 1, the airbag 32 comprising an airbag shell 321 and a buoyancy enhancement substance 322, the buoyancy enhancement substance 322 being a gas.

Since the structural features of the bag 1, the airtight zipper 2, and the opening 13 are the same as those of the first embodiment described earlier in this application, the explanations will not be repeated herein, and the focus herein will be on the air bladder 32 of the buoyancy enhancement assembly 3.

In this embodiment, the airbag 32 comprises an airbag shell 321 and a buoyancy enhancer 322, the airbag shell 321 is mounted to an outer peripheral wall of the bag body 1 and forms a second containment cavity (not shown) with the bag body 1, and the buoyancy enhancer 322 fills the second containment cavity.

In other embodiments, the buoyancy enhancement assembly 3 may also be disposed at a location other than the outer peripheral wall of the bag 1, or may be disposed inside the bag 1.

It should be noted that the buoyancy enhancer 322 can be a gas or some light and soft material, and the light and soft material can be EPE pearl cotton, or other substances such as sponge, EVA cotton, etc., as long as it can play a role in the floating effect, which is used to enhance the buoyancy generated by the airbag shell 321, so as to make a larger weight of the cell phone float on the surface of the water for the user to use.

Further, as shown in FIG. 11, the airbag shell 321 also has an airbag shell welding surface 3211, and the airbag shell 321 wraps the buoyancy enhancer 322 and then is fully scaled and welded by the airbag shell welding surface 3211 and the bag body 1, and the buoyancy enhancer assembly 3 does not need a complicated process such as inflating and valve valves after the fully sealed weld to produce stable shape and buoyancy force, which is convenient for the user to use in order to improve the user's experience. The user's experience can be improved.

Further, as shown in FIG. 11, the prongs on the side of the airbag shell 321 backing away from the bag body 1 are all arcuate. Specifically, the prongs on the side of the airbag shell 321 away from the bag body 1 are provided with airbag arcuate surfaces 3212, and the radius of the airbag arcuate surfaces 3212 is 3 mm-25 mm. It is to be noted that, compared to a right angle, the airbag arcuate surfaces 3212 can prevent the waterproof bag for cell phones from bumping or cutting the user's skin, which may cause injury to the user.

In other embodiments, the prongs on the side of the airbag shell 321 backing away from the bag body 1 may also be right-angled, and the airbag shell 321 may be manufactured using an injection molding process method.

In addition, the height of the air bladder shell 321 is 6 mm-25 mm. preferably, the height of the air bladder shell 321 is 12 mm. this height can avoid the problem that the height of the air bladder shell 321 is too low leading to insufficient buoyancy provided and difficulty in supporting a cell phone with a large weight, or that the height of the air bladder shell 321 is too high leading to inconvenience for the user in storing and carrying the air bladder shell 321, which affects the aesthetics of the cell phone waterproof bag.

Further, as shown in FIG. 11, the filled airbag shell 321 has a rectangular cross-section along the length and width directions.

It should be noted that due to the limited space on the backside of bag 1, the airbag shell 321 has a rectangular cross-section with the advantage of obtaining a large buoyancy force to allow a medium or large cell phone of up to 270 grams to float on the surface of the water after being loaded into the bag 1, which meets the floatation needs of the majority of large cell phones.

Preferably, the buoyancy can be up to 220 grams when the airbag shell 321 has a length of 90 mm, a width of 90 mm, and a height of 12 mm, 270 grams when the airbag shell 321 has a length of 120 mm, a width of 90 mm, and a height of 12 mm, and 17 mm when the airbag shell 321 has a length of 120 mm, a width of 90 mm, and a height of 17 mm can reach 340 grams.

In other embodiments, the length width, and height of the airbag shell 321 may also be of other dimensions.

In another embodiment, as shown in FIG. 12, the airbag shell 321 has a hexagonal cross-section, specifically two oblique corners are subtracted from one side of the rectangle, and the cell phone can be put in or taken out more conveniently after subtracting the two oblique corners, and furthermore, the cross-section of the airbag shell 321 can be a square, an axisymmetric hexagon, a trapezoid, a hexagon, a triangle, a circle, and other shapes.

As shown in FIGS. 9 to 10, to facilitate the user to open or close the airtight zipper 2, the auxiliary pulling structure 4 is provided on the bag body 1, and the pull tag 21 of the airtight zipper 2 can cooperate with the auxiliary pulling structure 4 to open or close the airtight zipper 2; in this embodiment, the auxiliary pulling structure 4 is preferably the pulling ring 41, and it can be appreciated that, when it is necessary to open (or close) the airtight zipper 2, the user can easily open (or close) the airtight zipper 2 using the interplay between the pull ring 41 and the pull tag 21.

Further, as shown in FIG. 4, the airtight zipper 2 and the opening 13 are set eccentrically along the center axis of the width direction of the lower narrow portion 12 in the direction of the opening of the airtight zipper 2, with an eccentricity distance ranging from 3 mm to 25 mm, so that the puller 22 will not interfere with the placement or removal of the cell phone after the eccentric setting.

In this embodiment, an eccentricity of 5 mm is preferred, and after the eccentricity is set, when the user opens the airtight zipper 2 to place or take out the cell phone, because there is a wide enough place for the cell phone to be placed, there will not be an interference situation with the slider 22. FIG. 4 is a schematic diagram of the effect of setting the center axis along the width direction of the lower narrow part 12 to the opening direction of the airtight zipper 2 with an eccentricity of 5 mm. FIG. 4 is a diagram of the closed state of the airtight zipper 2, and the airtight zipper 2 of FIG. 4 is in the open direction to the right. In addition, the eccentric setting can not only solve the problem of conveniently picking up the cell phone but also minimize the width of the bag body 1.

It should be noted that since the direction in which the airtight zipper 2 is set in the opening 13 can be rotated by any 180 degrees, the airtight zipper 2 can be set to open to the left or the right, so the airtight zipper 2 and the opening 13 are set to which side of the eccentricity will depend on the direction in which the airtight zipper 2 is opened, in short, the airtight zipper 2 is opened in which direction the airtight zipper 2 is opened will need to be set in which direction the airtight zipper 2 is opened. In short, in which direction the airtight zipper 2 open, the airtight zipper 2 and the opening 13 need to be set eccentrically.

The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application is subject to various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of the claims of this application.
