Description

Technical Field

[0001] The present invention relates to the technical field of waterproof bags, and particularly to a waterproof bag with internal communication. Background Art

[0002] A mobile phone waterproof bag is a protective device specifically designed to protect mobile phones from external environments such as water, dust, and sand. It is usually made of transparent waterproof materials, can be used in various environments, has good waterproof performance, and can effectively block the infiltration of moisture.

[0003] Existing single-layer waterproof bags have significant defects in the charging usage scenario. When users need to place the mobile phone and the power bank together, they are prone to friction and collision due to movement in a single enclosed space (the power bank frequently contacts and rubs against the mobile phone during walking). This phenomenon will cause scratches on the mobile phone screen and touch failure, and the problem of charging cable entanglement is prominent. Especially in dynamic scenarios such as cycling and rowing, the disorderly movement between devices will further reduce the usage experience.

[0004] Although there are waterproof bags with sandwich partitions in the prior art, their sandwich layers are completely isolated designs. Only one end of the two layers is connected, and the other end can swing freely, which also causes the mobile phone and the power bank to easily collide during movement, thereby causing a certain degree of damage to the mobile phone and the power bank. Summary of the Invention

[0005] The purpose of the present invention is to provide a waterproof bag with internal communication to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A waterproof bag with internal communication includes a bag body; it also includes a hanging shell. A cord is provided on the connecting shell. A strip-shaped groove is opened at the bottom of the hanging shell. One side of the connecting shell has an opening, and a flip cover is hinged to the side with the opening. The bag body includes a main bag, a sub-bag, and a mouth. The bag body is in a herringbone structure. Both the main bag and the sub-bag communicate with the mouth. A sealed track zipper is provided at the mouth of the bag body. Support strips are symmetrically and fixedly connected to the outer wall of the bag body at the mouth. The width of the two support strips is greater than that of the strip-shaped groove. An attaching structure is provided on the side of the main bag close to the sub-bag, and the attaching structure is used to paste the side of the main bag close to the sub-bag together.

[0008] With the above technical solution, by setting the bag body in a herringbone structure, the bag body includes a main bag and a sub-bag that branch out, which are respectively used to place a power bank and a mobile phone, thus avoiding the situation of mutual friction when the two are placed in the same bag; and an attachment structure is provided on the side where the main bag and the sub-bag are close to each other, which is used to attach the main bag and the sub-bag together, avoiding the things in the main bag and the sub-bag from colliding with each other during use; the mouth of the bag body is sealed by a sealed track zipper, which is convenient to open and take things; support strips are provided on both sides of the bag body. After the bag body is sealed, the support strips are slid into the connection shell, and the bag body fits against the inner wall of the strip-shaped groove. After completely sliding in, the flip cover is closed, and then the bag body can be worn around the neck through the cord.

[0009] A further improvement of the technical solution of the present invention lies in: the attachment structure includes a support plate, and knitting tapes are fixedly connected to both ends of the support plate. One of the knitting tapes is fixedly connected to the main bag, the soft hair surface of the magic tape is fixedly connected to the other knitting tape, and the prickly hair surface of the magic tape is fixedly connected to the outer side wall of the sub-bag. The magic tape includes a soft hair surface and a prickly hair surface, and the prickly hair surface is connected to the sub-bag, and the prickly hair surface is set to be strip-shaped.

[0010] With the above technical solution, the attachment structure is set as a magic tape, and the prickly hair surface of the magic tape is strip-shaped, and the soft hair surface can rotate at any angle with the flexible structure of the knitting tape, and after rotating to a certain angle between the support plate (rigid) and the sub-bag, the soft hair surface is adhered to the prickly hair surface, so that the support plate, the main bag and the sub-bag form a triangular structure, and the waterproof bag can be used as a mobile phone stand.

[0011] A further improvement of the technical solution of the present invention lies in: a partition piece is fixedly connected between the inner sides of the mouth, and a plurality of wire-winding pieces are fixedly connected to one side of the partition piece. Wire grooves are symmetrically opened on the wire-winding pieces, and the edge parts of the wire grooves are set as rounded corners.

[0012] With the above technical solution, by setting a partition piece at the mouth, the charging cable must bypass the partition piece to enter the bag where the mobile phone is placed, and wire-winding pieces are provided to wind the charging cable on the wire-winding pieces. On the one hand, the free-moving cable part is reduced, avoiding the cable from blocking the screen, and on the other hand, the problem of cable entanglement is avoided.

[0013] A further improvement of the technical solution of the present invention lies in: the adhesion parts on both sides and the bottom of the bag body are all set as solids, and air channels are opened on the solid parts. The air channels communicate with the inside of the bag body. Pipe bodies communicating with the air channels are symmetrically and fixedly connected to both sides of the bag body. A check valve is arranged inside the pipe body, and a suction component is arranged inside the connection shell. The suction component is used to evacuate the inside of the bag body through the pipe body; a plurality of spherical protrusions are arranged on the inner wall of the air channel.

[0014] By adopting the above technical solution, by setting up an air suction component, the inside of the bag body can be vacuumed through the airway, so that the inside of the bag body is in a negative pressure sucked deflated state when in use, reducing the friction between the mobile phone and the bag body; wherein a check valve is arranged inside the tube body, so that air can only be ventilated from the bag body to the outside in one direction, thereby preventing external air from entering the bag body through the airway;

[0015] On the other hand, by providing the above-mentioned suction component, it is also possible to determine whether the bag is leaking (detecting the sealing property). When the mouth or other parts of the bag are leaking, the bag cannot be deflated, thereby realizing the detection of its sealing property.

[0016] The cam is connected with two second sliding rods on the top of the connecting shell, and the top of the second sliding rod is fixedly connected with two second sliding rods on the top of the connecting shell, and the top of the second sliding rod is fixedly connected with the rope buckle, and the bottom of the second sliding rod extends to the interior of the connecting shell and is fixedly connected with the supporting plate, and the outside of the second sliding rod is covered with a spring.

[0017] The above technical solution is adopted, by setting the air suction component to a structure that can automatically inhale air with the vibration generated by the movement of the user, it can be realized without electric drive and special operation, which is convenient for use; specifically, when the user moves, the spring is compressed under the gravity of the waterproof bag and its internal objects, and shakes up and down during the movement, the rope buckle moves relative to the connecting shell, the first slide bar and the second slide bar slide relative to the connecting shell, the piston cylinder moves with the first slide bar, and the piston plate and the hollow rod are fixed to the fixed plate, so that the piston plate moves relative to the piston cylinder during the shaking process. When the piston plate moves downward relative to the piston cylinder, negative pressure is generated inside the piston cylinder. In this state, the check valve at the bottom of the exhaust pipe is blocked and the check valve inside the tube body is turned on, so that vacuum is drawn into the bag body through the airway; when the piston plate moves upward relative to the piston cylinder, positive pressure is generated inside the piston cylinder. In this state, the check valve at the bottom of the exhaust pipe is turned on and the check valve inside the tube body is blocked, so that the air inside the piston cylinder is discharged. The above process is automatically performed during the user's movement, so that no additional operation is required, avoiding the waste of user time.

[0018] A further improvement of the technical solution of the present invention lies in that: a plurality of hydrophobic holes are provided inside the solid at the bottom of the bag body. Confluence cavities are provided at both ends of the hydrophobic holes inside the solid. The air duct is communicated with the lower part of the confluence cavity. The plurality of hydrophobic holes are communicated with each other through pore channels, and the hydrophobic holes are communicated with the inside of the bag body through pore channels.

[0019] With the above technical solution, when water enters the bag body, the water penetrates downward through the pore channels and enters the hydrophobic holes (there is also the air pressure effect of the suction structure to evacuate the air during the process), and then passes through the confluence cavity, the air duct and the pipe body in sequence and then enters the exhaust pipe, and the water in the exhaust pipe is discharged during the exhaust operation, so as to realize automatic drainage during water seepage.

[0020] A further improvement of the technical solution of the present invention lies in that: the bottom inside the bag body is arranged in an arc structure with a convex middle part and concave sides. The part where the hydrophobic hole is communicated with the bag body is at the lowest position of the arc structure, and a plurality of heightening strips are fixedly connected at equal intervals on the arc structure.

[0021] With the above technical solution, in response to the situation where a small amount of water seeps in, since the placement position of electronic products such as mobile phones is at the higher position of the arc structure in the middle (the gaps on both sides of the arc structure are not enough for the mobile phone to be placed), and the water will seep to the lower positions on both sides. The middle position is further heightened by the heightening strips, further reducing the situation where water touches the electronic products.

[0022] A further improvement of the technical solution of the present invention lies in that: two ball plunger structures are symmetrically installed inside the flip cover, and clamping holes are symmetrically provided on both sides of the connecting shell. The clamping holes are through holes, and the ball plunger structures are used in cooperation with the through holes.

[0023] With the above technical solution, by pressing the ball head in the ball plunger structure, the ball head is separated from the clamping hole, so that the flip cover can be opened. When closing the flip cover, first press the ball head in the same way until the flip cover presses the arc surface of the ball head, then release the ball head and continue to operate the flip cover until the ball head is directly opposite to the clamping hole to complete the closing.

[0024] Due to the adoption of the above technical solution, the technical progress achieved by the present invention compared with the prior art is:

[0025] 1. The present invention provides an internally interconnected waterproof bag, which is configured as a herringbone structure. The bag body includes a bifurcated main bag and a secondary bag, which are respectively used to place a power bank and a mobile phone, thereby avoiding the mutual friction between the two when placed in the same bag; and an attachment structure is provided on the side close to the main bag and the secondary bag, which is used to attach the main bag and the secondary bag together, thereby avoiding the mutual collision between the main bag and the secondary bag during use; the mouth of the bag body is sealed by a sealed track zipper, and the switch is convenient for taking; support strips are provided on both sides of the bag body, and after the bag body is sealed, the support strips are slid into the connecting shell, the bag body is fitted with the inner wall of the strip groove, and is completely slid into the flip cover on the back cover, so that the bag body can be worn around the neck by a rope.

[0026] 2. The present invention provides an internally interconnected waterproof bag, wherein the attachment structure is configured as Velcro, wherein the bristle surface of the Velcro is in a strip shape, and the soft fur surface can be rotated at any angle by the flexible structure of the woven belt, and after being rotated until a support plate (hard) and the auxiliary bag form a certain angle, the soft fur surface is adhered to the bristle surface, so that the support plate, the main bag and the auxiliary bag form a triangular structure, and the waterproof bag can be used as a mobile phone holder.

[0027] 3. The present invention provides an internally interconnected waterproof bag. By providing an air suction component, the interior of the bag can be vacuumed through the airway, so that the interior of the bag is in a negative pressure deflated state when in use, thereby reducing the friction between the mobile phone and the bag. A check valve is provided inside the tube body, so that air can only be ventilated from the bag to the outside in one direction, thereby preventing external air from entering the bag through the airway. By providing the above-mentioned air suction component, it is also possible to determine whether the bag is leaking (testing its sealing). When its mouth or other parts of the bag are leaking, the bag cannot be deflated, thereby realizing the detection of its sealing.

[0028] 4. The present invention provides an internally interconnected waterproof bag, which can automatically inhale air by arranging the air suction component into a structure that can automatically inhale air with the vibration generated by the movement of the user, without the need for electric drive and special operation, and is convenient to use; specifically, when the user moves, the spring is compressed under the gravity of the waterproof bag and its internal objects, and shakes up and down during the movement, the rope buckle moves relative to the connecting shell, the first slide bar and the second slide bar slide relative to the connecting shell, the piston cylinder moves with the first slide bar, and the piston plate and the hollow rod are fixed to the fixed plate, so that the piston plate moves relative to the piston cylinder during the shaking process. When the piston plate moves downward relative to the piston cylinder, negative pressure is generated inside the piston cylinder. In this state, the check valve at the bottom of the exhaust pipe is blocked and the check valve inside the tube body is turned on, so that vacuum is drawn into the bag body through the airway; when the piston plate moves upward relative to the piston cylinder, positive pressure is generated inside the piston cylinder. In this state, the check valve at the bottom of the exhaust pipe is turned on and the check valve inside the tube body is blocked, so that the air inside the piston cylinder is discharged. The above process is automatically performed during the user's movement, so that no additional operation is required, avoiding the waste of user time.

[0029] 5. The present invention provides a waterproof bag with internal communication. When water enters the inside of the bag body, the water penetrates downward through the pore channels and enters the hydrophobic pores (there is also the air pressure effect of the air suction structure during the process of vacuum pumping), and then passes through the confluence chamber, the air duct, and the pipe body in sequence and enters the exhaust pipe, and the water in the exhaust pipe is discharged during the exhaust operation, so as to realize automatic drainage during water seepage.

Detailed implementation mode

[0041] The present invention will be further described in detail below in conjunction with embodiments:

[0042] Embodiment 1

[0043] As Figure 1 , Figure 3 and Figure 6 shown, the present invention provides a waterproof bag with internal intercommunication, including a bag body; further including a hanging shell, a cord 203 is arranged on the connecting shell 201, a strip-shaped groove is opened at the bottom of the hanging shell, one side of the connecting shell 201 is provided with an opening, and a flip cover 202 is hinged to the side with the opening. The bag body includes a main bag 101, a sub-bag 102 and a mouth 103, and the bag body is in a herringbone structure. The main bag 101 and the sub-bag 102 are both communicated with the mouth 103. A sealed track zipper 108 is arranged at the mouth 103 of the bag body. Support strips 107 are symmetrically and fixedly connected to the outer wall of the bag body at the mouth 103. The width of the two support strips 107 is greater than that of the strip-shaped groove. An attaching structure is arranged on the side of the main bag 101 close to the sub-bag 102. The attaching structure is used to paste the side of the main bag 101 close to the sub-bag 102 together.

[0044] In this embodiment, by setting the bag body in a herringbone structure, the bag body includes a forked main bag 101 and sub-bag 102, which are respectively used to place a power bank and a mobile phone, thus avoiding the situation of mutual friction when the two are placed in the same bag; and an attaching structure is arranged on the side of the main bag 101 close to the sub-bag 102, which is used to attach the main bag 101 and the sub-bag 102 together, avoiding the mutual collision of the things in the main bag 101 and the sub-bag 102 during use; the mouth 103 of the bag body 1 is sealed by a sealed track zipper 108, which is convenient to open and take; support strips 107 are arranged on both sides of the bag body. After the bag body is sealed, the support strips 107 are slid into the connecting shell 201, the bag body fits with the inner wall of the strip-shaped groove, and after it is completely slid in, the flip cover 202 is closed, and the bag body can be worn around the neck through the cord 203.

[0045] Example 2

[0046] As Figure 2 、 Figure 4 and Figure 5 shown, on the basis of Example 1, the present invention provides a technical solution: Preferably, the attaching structure includes a support plate 601, and both ends of the support plate 601 are fixedly connected with braided belts 602. One of the braided belts 602 is fixedly connected with the main bag 101, the soft hair surface 603 of the magic tape is fixedly connected to the other braided belt 602, and the prickly hair surface 604 of the magic tape is fixedly connected to the outer side wall of the secondary bag 102. The magic tape includes a soft hair surface 603 and a prickly hair surface 604. The prickly hair surface 604 is connected to the secondary bag 102, and the prickly hair surface 604 is arranged in a strip shape.

[0047] In this embodiment, the attaching structure is set as a magic tape, and the prickly hair surface 604 of the magic tape is in a strip shape. The soft hair surface 603 can rotate at any angle with the flexible structure of the braided belt 602, and after rotating to a certain angle between the support plate 601 (rigid) and the secondary bag 102, the soft hair surface 603 is adhered to the prickly hair surface 604, so that the support plate 601, the main bag 101 and the secondary bag 102 form a triangular structure, and the waterproof bag can be used as a mobile phone stand.

[0048] As Figure 3 and Figure 7 shown, preferably, a partition piece 104 is fixedly connected between the inner sides of the mouth part 103. One side of the partition piece 104 is fixedly connected with a plurality of wire winding pieces 105. Wire grooves 106 are symmetrically arranged on the wire winding pieces 105, and the edge parts of the wire grooves 106 are set as rounded corners.

[0049] Since the above design is based on the situation of using a power bank simultaneously, and a charging cable is usually required during the charging process. During the movement of the user, the charging cable is likely to be entangled or displaced into the bag where the mobile phone is located, thus blocking the screen and affecting the use;

[0050] In this embodiment, by arranging the partition piece 104 at the mouth part 103, the charging cable must bypass the partition piece 104 to enter the bag where the mobile phone is placed, and the wire winding pieces 105 are arranged to wind the charging cable on the wire winding pieces 105. On the one hand, the free cable part is reduced, avoiding the cable from blocking the screen. On the other hand, the problem of cable entanglement is avoided.

[0051] Example 3

[0052] As Figure 3 and Figure 9As shown, on the basis of Embodiment 2, the present invention provides a technical solution: Preferably, the adhesion parts on both sides and the bottom of the bag body are set as solids, and air channels 301 are provided in the solid parts. The air channels 301 communicate with the inside of the bag body. Tube bodies 305 communicating with the air channels 301 are symmetrically and fixedly connected to both sides of the bag body. A check valve is provided inside the tube bodies 305. An air suction assembly is provided inside the connection shell 201. The air suction assembly is used to evacuate the inside of the bag body through the tube bodies 305; several spherical protrusions 7 are provided on the inner wall of the air channels 301.

[0053] In this embodiment, by providing the air suction assembly, the inside of the bag body can be evacuated through the air channels 301, so that the inside of the bag body presents a negative pressure and deflated state during use, reducing the friction between the mobile phone and the bag body; among them, a check valve is provided inside the tube bodies 305, so that air can only flow unidirectionally from the bag body to the outside, preventing external air from entering the bag body through the air channels 301;

[0054] On the other hand, by providing the above-mentioned air suction assembly, it is also possible to determine whether the bag body leaks (detect the airtightness). When the mouth 103 or other parts of the bag body leak, the bag body cannot be deflated, thereby realizing the detection of its airtightness.

[0055] In addition, since the bag body itself is made of a flexible material, even if there is a thicker structure in the solid part, when evacuating the negative pressure, it is still necessary to face the influence of negative pressure on the air channels 301 or the deformation influence caused during use (such as bending), which will cause the inability to evacuate the negative pressure inside the bag body. Therefore, spherical protrusions 7 are also provided inside the air channels 301 in this solution, so that no matter how the air channels 301 are indented and deformed, there are gaps for ventilation, avoiding the problem of blockage and inability to complete the air extraction.

[0056] Such as Figure 3 、 Figure 8 and Figure 9As shown in the figure, preferably, the air suction assembly includes a fixing plate 510 fixedly connected between the inner walls of the connection shell 201. Two hollow rods 507 are symmetrically and fixedly connected to the top of the fixing plate 510. One end of the hollow rod 507 away from the fixing plate 510 is fixedly connected with a piston plate 508. An air hole communicating with the inside of the hollow rod 507 is formed in the middle of the piston plate 508. One end of the hollow rod 507 away from the piston plate 508 is fixedly connected with an exhaust pipe 509. A check valve is arranged at the bottom end of the exhaust pipe 509. The pipe body 305 is communicated with the middle position of the exhaust pipe 509. Two first sliding rods 506 are symmetrically and slidably connected to the top of the connection shell 201. A rope buckle 501 is fixedly connected between the tops of the first sliding rods 506. The rope belt 203 is suspended on the rope buckle 501. One end of the first sliding rod 506 away from the rope buckle 501 extends into the connection shell 201 and is fixedly connected with a piston cylinder 505. The piston plate 508 is slidably connected with the inner wall of the piston cylinder 505. Two second sliding rods 502 are symmetrically and slidably connected to the top of the connection shell 201. The tops of the second sliding rods 502 are fixedly connected with the rope buckle 501. The bottoms of the second sliding rods 502 all extend into the connection shell 201 and are fixedly connected with a support plate 503. Springs 504 are sleeved on the outer parts of the second sliding rods 502.

[0057] Considering the actual use environment, users usually put the mobile phone and the power bank into use in a hurry. If vacuum is specially pumped, not only special portable equipment is needed to support, but also special operations are needed, making the use process more cumbersome.

[0058] In this embodiment, by setting the air suction assembly into a structure that can automatically suck air along with the vibration generated by the movement of the user, it can be realized without electric drive and special operation, which facilitates the use. Specifically, when the user moves, under the gravity of the waterproof bag and the objects inside it, the spring 504 is compressed, and it jitters up and down during the movement process. The rope buckle 501 moves relative to the connection shell 201. Both the first sliding rod 506 and the second sliding rod 502 slide relative to the connection shell 201. The piston cylinder 505 moves along with the first sliding rod 506, while the piston plate 508 and the hollow rod 507 are both fixed to the fixing plate 510, so that the piston plate 508 makes a piston movement relative to the piston cylinder 505 during the jittering process. When the piston plate 508 moves downward relative to the piston cylinder 505, negative pressure is generated inside the piston cylinder 505. In this state, the check valve at the bottom end of the exhaust pipe 509 is blocked and the check valve inside the pipe body 305 is conducted, so as to pump vacuum into the bag body through the air passage 301. When the piston plate 508 moves upward relative to the piston cylinder 505, positive pressure is generated inside the piston cylinder 505. In this state, the check valve at the bottom end of the exhaust pipe 509 is conducted and the check valve inside the pipe body 305 is blocked, so as to discharge the air inside the piston cylinder 505. The above process is automatically carried out along with the movement of the user, so no additional operation is required, avoiding the waste of the user's time.

[0059] It should be specifically noted that, along with the amount of air in the bag body (the bag body in a deflated state), the resistance of the piston plate 508 relative to the piston cylinder 505 also changes accordingly. That is, when there is less air in the bag body, the movement range of the piston plate 508 relative to the piston cylinder 505 is smaller, thereby reducing the amount of bag body vibration and generally tending to be stable.

[0060] As Figure 3 and Figure 9 shown, preferably, a number of hydrophobic holes 302 are provided inside the solid at the bottom of the bag body. Confluence cavities 304 are provided at both ends of the hydrophobic holes 302 inside the solid. The air duct 301 communicates with the lower part of the confluence cavity 304. A number of hydrophobic holes 302 communicate with each other through a hole channel 303, and the hydrophobic holes 302 communicate with the inside of the bag body through the hole channel 303.

[0061] In this embodiment, when water enters the inside of the bag body, the water penetrates downward through the hole channel 303 and enters the hydrophobic holes 302 (there is also the air pressure effect of the air suction structure during the process of evacuating to a vacuum), and then passes through the confluence cavity 304, the air duct 301, and the pipe body 305 in sequence and enters the exhaust pipe 509, and the water in the exhaust pipe 509 is discharged during the exhaust operation, thereby realizing automatic drainage during water seepage.

[0062] As Figure 3 and Figure 9 shown, preferably, the bottom inside the bag body is provided with an arc-shaped structure 401 that bulges in the middle and depresses on both sides. The position where the hydrophobic holes 302 communicate with the bag body is at the lowest position of the arc-shaped structure 401, and a number of heightening strips 402 are fixedly connected at equal intervals on the arc-shaped structure 401.

[0063] In this embodiment, to deal with the situation where a small amount of water seeps in, since the position where electronic products such as mobile phones are placed is at a relatively high position of the arc-shaped structure 401 in the middle (the gaps on both sides of the arc-shaped structure 401 are not large enough for a mobile phone to be placed), and the water will seep to the lower positions on both sides, and the middle position is further heightened by the heightening strips 402, further reducing the situation where water touches the electronic products.

[0064] As Figure 3 , Figure 6 and Figure 8 shown, preferably, two ball plunger structures 204 are symmetrically installed inside the flip cover 202. Through holes are symmetrically provided on both sides of the connection shell 201, and the through holes are through holes, and the ball plunger structures 204 are used in cooperation with the through holes.

[0065] In this embodiment, by pressing the ball head in the ball plunger structure 204, the ball head is separated from the through hole, so that the flip cover 202 can be opened. When closing the flip cover 202, also press the ball head first until the flip cover 202 presses the arc surface of the ball head, then release the ball head and continue to operate the flip cover 202 until the ball head is facing the through hole to complete the closing.

[0066] The working principle of the waterproof bag with internal communication will be specifically described below.
