[0047] Referring to the drawings, Figures 1-8 A vacuum waterproof bag, comprising:

[0048] A sealed bag 100 is provided with a sealing strip 110 at the bag opening of the sealed bag 100, and an air extraction port 120 is provided on the bag body of the sealed bag 100;

[0049] An air extraction device 200 is provided with an air inlet 210 and an air outlet 220, and an air passage is arranged in the air extraction device 200, which is communicated with the air inlet 210 and the air outlet 220, and a one-way air valve 300 is arranged in the air passage;

[0050] The air extraction device 200 is sealingly fixed on the bag body of the sealing bag 100, and the air inlet 210 of the air extraction device 200 is communicated with the air extraction port 120 on the bag body. The air extraction device 200 and the one-way air valve 300 are arranged to solve the problem of residual air in the existing waterproof bag, efficiently remove the air in the sealing bag 100, tightly fit the bag body with the equipment, and enhance the waterproof performance and user operation experience. The design of the air extraction device 200 fully considers convenience and reliability, so that users can efficiently extract air and seal the waterproof bag without the help of complex tools.

[0051] The sealing bag 100 is made of flexible transparent material such as PVC or TPU, which has high strength and excellent waterproof performance. The sealing strip 110 is arranged at the bag opening of the sealing bag 100 to complete the sealing operation of the bag opening after placing the equipment. One side of the bag body is provided with an air extraction port 120, which is communicated with the air inlet 210 of the air extraction device 200. The air extraction device 200 includes an air inlet 210, an air outlet 220 and an air passage connecting the two, and a one-way air valve 300 is arranged in the air passage. The one-way air valve 300 is used to control the one-way flow of air to ensure that the air can be discharged from the sealing bag 100 without backflow. The air extraction device 200 is fixed on the bag body of the sealing bag 100 through a sealing structure to ensure that the air passage is completely communicated with the air extraction port 120 of the bag body without air leakage.

[0052] The user places the mobile phone or other equipment in the sealing bag 100, adjusts it to the appropriate position, and then seals the bag opening with the sealing strip 110. The user starts the air extraction device 200 by squeezing, manually extracting air or other ways, and the air passage in the air extraction device 200 discharges air from the bag body through the air inlet 210 and the air extraction port 120. The one-way air valve 300 ensures that the air in the bag is discharged in one direction to prevent external air from flowing back to the inside of the bag. When the air in the bag is exhausted, the bag body is tightly fitted with the surface of the equipment, and the sealing strip 110 is stably sealed, completing the packaging of the vacuum waterproof bag.

[0053] By setting the air extraction device 200 in communication with the sealed bag 100, the air inside the bag can be quickly and completely exhausted to form a negative pressure environment. The application of the one-way air valve 300 ensures that the air flow is unidirectional and avoids backflow affecting the sealing effect. The negative pressure state after air extraction increases the adhesion of the sealing strip 110 to the bag body, significantly improving the waterproof performance of the bag body and enabling it to be used in deep water or high pressure environments. The close fit of the bag body to the surface of the device eliminates air gaps, improving touch screen sensitivity and operation feel, making it particularly suitable for underwater use. Users can operate the air extraction device 200 without additional tools, making it convenient and efficient.

[0054] In this embodiment, the one-way air valve 300 is provided between the air extraction chamber 400 and the air inlet 210;

[0055] The one-way air valve 300 is provided between the air extraction chamber 400 and the air inlet 210;

[0056] When the air extraction chamber 400 is contracted, the air extraction chamber 400 is discharged along the one-way air valve 300;

[0057] When the air extraction chamber 400 is reset, a negative pressure is generated to extract air from the sealed bag 100 through the air inlet 210 and the air outlet 120. To solve the problem of inefficient air extraction inside the waterproof bag, an air extraction device 200 based on the cooperative work of the air extraction chamber 400 and the one-way air valve 300 is designed. Through the mechanical contraction and reset action of the air extraction chamber 400, combined with the one-way control function of the one-way air inlet device, air is efficiently exhausted from the sealed bag 100, avoiding backflow of external air. This design is not only simple and reliable, but also ensures the air extraction efficiency and sealing effect of the waterproof bag.

[0058] The air extraction chamber 400 is located in the core area of the air extraction device 200, one end of which is connected to the air outlet 120 of the sealed bag 100 through the air inlet 210, and the other end is in communication with the outside through the one-way air valve 300. The air extraction chamber 400 is made of flexible material such as silicone or elastic plastic, which has good compressibility and durability. The one-way air inlet device is arranged inside the air extraction chamber 400 and covers the air inlet 210, ensuring that air can only enter the air extraction chamber 400 from the sealed bag 100 and cannot flow back.

[0059] The user presses the air extraction chamber 400, the air inside the chamber is discharged along the one-way air valve 300, the valve plate 500 automatically closes to prevent external air from flowing back into the sealed bag 100. The user releases the pressing force, the air extraction chamber 400 returns to its original state under the action of the flexible material or the reset spring 600, generating a negative pressure, and the air inside the sealed bag 100 is sucked into the air extraction chamber 400.

[0060] Through repeated contraction and reset actions by the user, the air inside the sealed bag 100 is gradually completely exhausted until the bag body is attached to the surface of the device.

[0061] The flexible design of the air extraction chamber 400 enables rapid and efficient air extraction from the sealed bag 100, while the one-way air valve 300 prevents air backflow, achieving one-way control throughout the process. The air extraction operation is simple and intuitive, suitable for user manual operation. The negative pressure environment not only completely evacuates the air in the bag, but also improves the adhesion of the bag body to the sealing strip 110, thereby enhancing the waterproof performance of the bag body. The design of the valve plate 500 of the one-way air inlet device ensures precise control of air flow direction, avoids air backflow, and has high reliability. Under negative pressure, the bag body closely adheres to the surface of the device, significantly improving the sensitivity of the touch screen, and the operation feels close to that of a bare machine. In underwater or wet hand environments, the touch screen operation is smooth and has no lag, providing a better user experience. The design of the air extraction chamber 400 is simple and can be flexibly adapted to sealed bags 100 of different sizes and shapes, meeting the waterproof needs of various devices. It is particularly suitable for dynamic scenarios such as water parks, diving, and outdoor photography, improving the safety and operation convenience of the device. The design of the air extraction chamber 400 and the one-way air valve 300 avoids complex mechanical structures and achieves stable and efficient air extraction through simple physical principles. This design solves the problems of existing waterproof bags, such as inability to extract air and poor sealing performance, and is suitable for a variety of high-end user groups, with a wide market prospect.

[0062] In this embodiment, the one-way air inlet device is a valve plate 500, which covers the air inlet 210;

[0063] When the air extraction chamber 400 is contracted, the valve plate 500 covers the air inlet 210 to form a seal;

[0064] When the air extraction chamber 400 is reset, the valve plate 500 separates from the air inlet 210 under the action of negative pressure to allow air flow. The one-way air inlet device uses a valve plate 500 structure, which controls the one-way flow of air by covering and leaving the air inlet 210. Compared with traditional air valves, the valve plate 500 design is simpler and more flexible, with high reliability and adaptability, meeting the needs of the air extraction chamber 400 and optimizing user experience.

[0065] The valve plate 500 covers the air inlet 210 and is made of flexible materials such as silicone, elastic plastic, or composite materials, with excellent flexibility and durability. The size of the valve plate 500 is larger than that of the air inlet 210, ensuring complete coverage when sealed and preventing air leakage.

[0066] When the air extraction chamber 400 is compressed by the user, the air flow in the chamber is discharged along the one-way air valve 300, forming a positive pressure on the valve plate 500. The valve plate 500 tightly adheres to the air inlet 210 under the action of pressure, forming a reliable seal to prevent external air from flowing back to the sealed bag 100 through the air inlet 210.

[0067] When the external force is released, the suction chamber 400 is reset under the action of the flexible material or the reset spring 600, and a negative pressure is formed in the chamber. At this time, the valve piece 500 is attracted by the negative pressure and separated from the air inlet 210, and the air in the sealed bag 100 enters the suction chamber 400 through the air inlet 210, realizing one-way air extraction.

[0068] The valve piece 500 has a relatively simple structure, does not require complex mechanical components or processing technology, and can be produced only by high-precision mold forming, thereby reducing manufacturing costs. The connection of the valve piece 500 and the air inlet 210 does not require additional fixing devices, is easy to install, and has high assembly efficiency. The valve piece 500 is made of flexible material and can tightly adhere to the air inlet 210 under the action of pressure, thereby realizing efficient sealing. Even in long-term use or high-pressure environments, the durability and anti-deformation ability of the flexible material ensure stable sealing performance. The valve piece 500 is light and thin, has fast response speed, and can quickly complete the opening and closing action according to the pressure change of the suction chamber 400, thereby ensuring the timeliness of air flow control. The adhesion and separation of the valve piece 500 and the air inlet 210 rely on simple physical forces, without additional mechanical driving, thereby avoiding faults or delays caused by complex structures. The light and thin design of the valve piece 500 has small resistance to air flow, especially under the negative pressure attraction during reset, so that air can quickly pass through the air inlet 210, thereby significantly improving the air extraction efficiency. Compared with traditional air valves, the valve piece 500 does not require complex moving parts, and has lower material and production costs.

[0069] In the embodiment, the reset spring 600 is arranged in the suction chamber 400 and is used to drive the reset of the suction chamber 400. The reset spring 600 is arranged in the suction chamber 400, which is designed to realize the rapid rebound reset of the suction chamber 400 after each compression by the elastic reset ability of the spring, thereby forming a negative pressure in the chamber and continuously extracting air in the sealed bag 100. This design does not require external power support, has a simple and efficient structure, and provides a reliable reset mechanism for the manual operation of the air extraction device 200.

[0070] When the user applies an external force to the suction chamber 400, the air in the chamber is discharged through the one-way air valve 300, and the reset spring 600 is compressed to store elastic potential energy. After the external force is released, the reset spring 600 drives the chamber to return to the original state by using the elastic potential energy, and a negative pressure is formed during the reset of the chamber, thereby sucking the air in the sealed bag 100 and completing one cycle of the air extraction process. The user can continuously extract the air in the sealed bag 100 by multiple compression and reset operations by using the elastic recovery ability of the reset spring 600, until the air is exhausted.

[0071] The addition of the reset spring 600 enables the air extraction chamber 400 to automatically reset after each compression, eliminating the need for the user to manually pull the chamber back into position. This makes the operation more convenient and efficient. The stable negative pressure generated during the spring reset process ensures that the chamber can continuously extract air from the sealed bag 100, resulting in higher exhaust efficiency. The mechanical properties of the spring are stable, allowing it to maintain the reset function of the chamber for a long time, significantly extending the service life of the air extraction device 200. Through the rapid recovery capability of the reset spring 600, the user can perform continuous air extraction operations at a higher frequency, significantly reducing the exhaust time.

[0072] In this embodiment, the top end of the air extraction chamber 400 is provided with a limiting boss 410 for fixing the reset spring 600. The limiting boss 410 is located in the top ring of the reset spring 600, and the bottom ring of the reset spring 600 presses the valve piece 500. To ensure that the reset spring 600 can operate stably in the air extraction chamber 400, a limiting boss 410 structure for fixing the reset spring 600 is designed. This structure fixes the top ring of the reset spring 600 at the top end of the air extraction chamber 400, while allowing the bottom ring to press the valve piece 500, so that the reset spring 600 can provide both reset force and effectively maintain the sealing state of the valve piece 500, thereby ensuring the efficient operation of the air extraction device 200.

[0073] The limiting boss 410 is located at the top end of the air extraction chamber 400, with a moderate height and a diameter matching the top ring of the reset spring 600, ensuring that the spring can be securely installed on the boss. The limiting boss 410 prevents the reset spring 600 from shifting, slipping, or failing during use through mechanical limiting, maintaining the axial stress state of the reset spring 600. The top ring of the reset spring 600 is nested on the outer edge of the limiting boss 410, which serves as a fixed point to ensure that the spring maintains a stable position during operation. The bottom ring of the reset spring 600 directly presses the valve piece 500 at the bottom of the air extraction chamber 400, providing appropriate downward pressure to ensure that the valve piece 500 is tightly attached to the air inlet 210 in the non-working state, ensuring the air tightness of the air inlet 210.

[0074] When the air extraction chamber 400 is compressed, the reset spring 600 is also compressed, and the limiting boss 410 limits the movement of the top ring of the spring, maintaining the axial stress of the spring. At this time, the valve piece 500 is tightly attached to the air inlet 210 due to the positive pressure in the chamber, completing the sealing. When the external force is released, the reset spring 600 pushes the air extraction chamber 400 back to its original position under the elastic force, creating a negative pressure in the chamber. The bottom ring pressure decreases, and the valve piece 500 is attracted away from the air inlet 210, allowing air from the sealed bag 100 to enter the chamber through the air inlet 210. Through the fixing action of the limiting boss 410, the reset spring 600 maintains a stable position during repeated compression and reset actions, ensuring the efficiency and reliability of the entire device.

[0075] The reset spring 600 is fixed by the limiting boss 410 and the valve plate 500, without the need for complex clamping or additional mounting parts, and the installation process is quick and simple.

[0076] In this embodiment, a sealing cover 700 is arranged at the air outlet 220.

[0077] The air outlet 220 is provided with a limiting window with air holes, one side of which is fixed with an elastic member, and the sealing cover 700 is located on the other side of the limiting window, and the elastic member is connected with the sealing cover 700.

[0078] When the air flow in the air duct is discharged, the air flow lifts the sealing cover 700 and separates from the limiting window to overflow to the outside.

[0079] When the air flow in the air duct is discharged, the elastic member exerts a pre-tightening force to cover the limiting window with the sealing cover 700 to form a seal.

[0080] In order to ensure that the air outlet 220 of the air extraction device 200 can work reliably when the air flow is discharged and static, a sealing structure composed of the sealing cover 700, the limiting window and the elastic member is designed. This design can automatically open the air outlet 220 when the air flow is discharged, and restore the sealing state when static, which not only ensures the smooth discharge of the air flow, but also effectively prevents the outside air or moisture from flowing back to the inside of the device through the air outlet 220.

[0081] The sealing cover 700 is located on the outside of the air outlet 220, used to cover the air holes of the limiting window in the static state to form a seal. The sealing cover 700 is usually made of hard or flexible material, with high sealing performance. The limiting window is arranged at the air outlet 220, with a plurality of air holes allowing air flow to pass through. When the air flow is discharged, the sealing cover 700 is lifted, and the limiting window plays a supporting and guiding role. The elastic member such as spring or flexible rubber column connects the sealing cover 700 and one side of the limiting window, providing pre-tightening force for the sealing cover 700. When there is no air flow discharge, the elastic member makes the sealing cover 700 tightly adhere to the limiting window, maintaining the sealing state.

[0082] When the air extraction chamber 400 is compressed, the air flow pressure in the air duct increases, and the air flow is discharged outward from the air outlet 220. The air flow lifts the sealing cover 700, making it separate from the limiting window, opening the air outlet channel, and the air flow overflows to the outside through the air holes of the limiting window. When the air flow in the air duct stops, the pre-tightening force of the elastic member makes the sealing cover 700 automatically restore to the surface of the limiting window, covering the air holes to form an air-tight seal, preventing the outside air or moisture from flowing back.

[0083] The sealing cover 700 can be automatically opened under the action of air flow to complete the discharge of air flow; when the air flow stops, it is automatically closed under the action of the elastic member to maintain the sealing state of the air outlet 220. The cooperation of the sealing cover 700 and the elastic member ensures that the air outlet 220 is completely sealed when it is static, effectively preventing external air or moisture from flowing back to the air extraction device 200 or the inside of the sealing bag 100 through the air outlet 220. The stable pre-tightening force provided by the elastic member ensures smooth switching of the sealing cover 700 between the sealing and opening states, reduces the wear of mechanical components, and enhances the service life of the device. The support of the limiting window to the sealing cover 700 prevents it from shaking or deviating during the exhaust process, ensuring the stability of the structure.

[0084] In the present embodiment, the elastic member is an elastic rubber column 710, which is integrally formed with the sealing cover 700. The elastic member adopts the form of an elastic rubber column 710 and is manufactured by integrally forming with the sealing cover 700. This design reduces the number of components, simplifies the structure and assembly process, improves the reliability and sealing performance of the overall device, and reduces production costs and manufacturing complexity, making it particularly suitable for efficient production and long-term use of portable air extraction devices 200.

[0085] The elastic rubber column 710 and the sealing cover 700 are integrally formed by a mold, making the rubber column and the sealing cover 700 into one whole, eliminating the connection link of traditional independent components. The rubber column provides pre-tightening force for the sealing cover 700 through its elastic properties, allowing the sealing cover 700 to quickly return to the sealing position after the air flow discharge stops.

[0086] When the air extraction chamber 400 is compressed, the air flow pressure lifts the sealing cover 700, and the rubber column is stretched, allowing the air flow to be discharged through the limiting window air hole. After the air flow stops, the elastic restoring force of the rubber column drives the sealing cover 700 to return to position, tightly adhering to the surface of the limiting window to form a reliable seal.

[0087] The integrally formed design makes the elastic member and the sealing cover 700 into one whole, without the need for additional connecting or fixing components, significantly simplifying the product structure. Reducing the number of components reduces mold manufacturing and assembly costs, improving production efficiency. The high-elasticity material of the rubber column can provide stable pre-tightening force to ensure that the sealing cover 700 tightly adheres to the surface of the limiting window when it is static, forming a reliable air-tight seal. The integrally formed design eliminates the possibility of micro-leakage caused by multiple component connections, improving the stability of the sealing performance.

[0088] In the embodiment, the air inlet 210 is provided with a dam 800 on the side of the air extraction. The dam 800 is provided with a gap 810. The dam 800 is arranged on the outside of the bag body. Its main function is to form a concave-convex structure area to prevent the two layers inside the bag body from completely adhering, thereby preventing the air extraction port 120 from being sealed. The combination of the dam 800 and the gap 810 can interfere with the adhesion of the bag body, so that the air flow can smoothly pass through the air extraction port 120 into the air extraction device 200 during the air extraction process. Compared with the traditional isolation method, this design directly acts on the structure outside the bag body, is simple, efficient and easy to implement.

[0089] The dam 800 is located around the air extraction port 120 on the outside of the bag body, adjacent to the area connected with the air inlet 210 of the air extraction device 200. The dam 800 forms a convex shape around the air extraction port 120, in the form of a closed loop or partial loop. The dam 800 is higher than the surface of the bag body, and the convex shape increases the unevenness of the structure outside the bag body. The dam 800 is provided with one or more gaps 810. The position and number of the gaps 810 are designed according to the air flow demand. The gap 810 is consistent with the air extraction direction and is used to guide the air flow.

[0090] The dam 800 forms a local concave-convex area inside and outside the bag body through its convex shape, preventing the two layers inside the bag body from completely adhering in the air extraction port 120 area. The gap 810 provides clear air flow guidance, so that the air flow can smoothly enter the air extraction port 120 through the concave-convex area without being blocked by the adhesion of the bag body. When the air extraction device 200 is fixed on the dam 800 area by adhesion and sealing, the air inlet 210 of the air extraction device 200 is connected with the air extraction port 120 of the bag body. The gap 810 of the dam 800 and the concave-convex area inside the bag body ensure the smooth exhaust of air.

[0091] The combination of the dam 800 and the gap 810 effectively prevents the two layers inside the bag body from adhering to the air extraction port 120 by changing the shape of the structure outside the bag body, solving the problem of air flow blockage caused by adhesion. The concave-convex area breaks the sealed state formed by the adhesion of the bag body, ensuring the stability and efficiency of the air extraction process. The gap 810 of the dam 800 provides a clear air flow channel, which can ensure that air is smoothly discharged through the air extraction port 120 regardless of the changes in the negative pressure inside the bag body.

[0096] The air extraction device 200 and the bag body are fixed by adhesive sealing, with stable sealing and high-efficiency air exhaust capacity. The one-way air valve 300 and the air extraction chamber 400 are provided, and through the mechanical compression and reset operation of the chamber, the air in the bag body is discharged in one direction, preventing the backflow of external air.

[0097] The reset spring 600 is arranged in the air extraction chamber 400, which is used to drive the chamber to reset and form negative pressure, further improving the air extraction efficiency. The reset spring 600 is fixed by the limiting boss 410, ensuring stable positioning of the spring, and the valve piece 500 is pressed by the spring bottom ring to enhance the sealing effect.

[0098] The sealing sleeve 900 is made of elastic material, which realizes double sealing protection by wrapping the air extraction device 200 and the bag opening of the bag body, effectively preventing moisture and gas from penetrating. The dam 800 is arranged outside the bag body, which prevents the formation of a closed space by the inner and outer adhesion of the bag body through the cooperation of the protrusions and notches 810, ensuring smooth air exhaust.

[0099] The air outlet 220 is equipped with a sealing cover 700 and a limiting window with air holes, the opening and closing of the sealing cover 700 is controlled by the pre-tightening force of the elastic member, the smoothness of the air flow is ensured when the air flow is discharged, and reliable sealing is formed when it is static.

[0100] The one-way air inlet device adopts a valve plate 500 structure, is light and efficient, automatically opens and closes through the action of air flow, ensures one-way discharge of gas, and has simple structure and low cost.

[0101] Through the design of the air extraction chamber 400 and the combination of the one-way air valve 300, a stable and reliable air discharge mechanism is formed, which ensures that the air in the bag body can be quickly and completely discharged.
