Description

Technical Field

[0001] The invention belongs to the technical field of waterproof bags and relates to a vacuum waterproof bag. Background Art

[0002] A mobile phone waterproof bag is a common waterproof protection product, usually made of transparent plastic or PVC material. It has waterproof, dustproof and sandproof functions and is suitable for use in humid or water environments, such as swimming, diving, beaches, water parks, etc. Its main function is to prevent moisture from penetrating into the mobile phone through a sealed structure, while allowing users to directly operate the mobile phone touch screen, take photos or record videos in the bag. One disadvantage of existing mobile phone waterproof bags is that there is no way to evacuate the air inside.

[0003] The failure to exhaust the air in the mobile phone waterproof bag will cause the following problems:

[0004] 1. The problem of residual air: the air in the waterproof bag cannot be effectively discharged, which causes the bag to increase in size and inconvenience in operation. When used in water, too much air creates excessive buoyancy, causing the bag to float unsteadily, increasing the risk of loss and affecting the stability of shooting and underwater use.

[0005] 2. Poor hand feel and insufficient touch screen sensitivity. Since the bag cannot fit tightly to the surface of the phone, the operation feels stiff and the touch screen sensitivity is significantly reduced, especially in wet hands or underwater environments. The touch operation has obvious lag and the experience is poor.

[0006] 3. The waterproof performance is unreliable. The residual air can easily squeeze the sealing strip when under pressure, causing local leakage and reducing the waterproof performance of the bag. It is especially prone to leakage in deep water or under stress, and cannot meet high protection requirements.

[0007] 4. The shooting effect is not good. The residual air and bubbles will cause light refraction, and the shooting picture will be blurred or distorted. At the same time, the optical performance of the transparent material of the bag is poor, which further affects the clarity of the shooting and the screen display effect.

[0008] Therefore, reducing the residual air in the waterproof bag has become an urgent problem to be solved. Summary of the invention

[0009] The purpose of the present invention is to provide a vacuum waterproof bag to address the deficiencies of the prior art. After a mobile phone is placed in the waterproof bag, the air remaining in the bag can be extracted so that the bag body fits tightly to the surface of the device.

[0010] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] A vacuum waterproof bag, comprising:

[0019] Furthermore, the one-way air intake device is a valve sheet, and the valve sheet covers the air intake port;

[0020] When the air extraction chamber contracts, the valve sheet covers the air inlet to form a seal;

[0022] Furthermore, a return spring is provided in the air pumping chamber, and the return spring is used to drive the air pumping chamber to return to its original position.

[0023] Furthermore, a limiting boss for fixing a return spring is provided at the top of the air extraction chamber, the limiting boss is located in the top circle of the return spring, and the bottom circle of the return spring presses the valve plate.

[0024] Furthermore, a sealing cover is provided at the air outlet;

[0025] A limiting window with air holes is provided at the air outlet, an elastic member is fixed on one side of the limiting window, the sealing cover is located on the other side of the limiting window, and the elastic member is connected to the sealing cover;

[0026] When air is discharged from the airway, the airflow lifts up the sealing cover and separates from the limit window to allow the airflow to overflow to the outside;

[0027] When air is discharged from the airway, the elastic member applies a pre-tightening force to make the sealing cover cover the limiting window to form a seal.

[0028] Furthermore, the elastic member is an elastic rubber column, and the rubber column and the sealing cover are integrally formed.

[0029] Furthermore, a dam is provided on the side of the air inlet facing the air extraction, and a notch is provided on the dam.

[0030] Furthermore, it also includes a sealing sleeve, which is arranged outside the air extraction device and wraps the air extraction device and the bag opening of the sealing bag.

[0031] Furthermore, the sealing sleeve is made of elastic material.

[0032] By applying the technical solution of the present invention, through the linkage design of the air extraction device and the sealing bag, the excess air can be efficiently removed after the mobile phone is placed in the sealing bag to form a vacuum state. The vacuum design makes the bag body fit tightly with the surface of the mobile phone, reduces the air gap, and improves the sensitivity of the touch screen.

[0047] Reference Figure 1-8 As shown, a vacuum waterproof bag comprises:

[0048] A sealed bag 100, wherein a sealing strip 110 is provided 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, wherein the air extraction device 200 is provided with an air inlet 210 and an air outlet 220, an air passage is provided inside the air extraction device 200, the air passage connects the air inlet 210 and the air outlet 220, and a one-way air valve 300 is provided inside the air passage;

[0050] The exhaust device 200 is sealed and fixed on the bag body of the sealing bag 100, and the air inlet 210 of the exhaust device 200 is connected to the exhaust port 120 on the bag body. The exhaust device 200 and the one-way air valve 300 are provided to solve the problem of residual air inside the existing waterproof bag, so as to achieve efficient removal of air from the sealing bag 100, achieve a close fit between the bag body and the device, and enhance the waterproof performance and user operation experience. The design of the exhaust device 200 fully considers convenience and reliability, so that users can achieve efficient exhaust and sealing functions of the vacuum waterproof bag without the help of complex tools.

[0051] The sealing bag 100 is made of a flexible transparent material such as PVC or TPU, and has high strength and excellent waterproof performance. A sealing strip 110 is provided at the bag opening of the sealing bag 100, which is used to complete the sealing operation of the bag opening after the device is placed. An air suction port 120 is provided on one side of the bag body, and the air suction port 120 is connected to the air inlet 210 of the air suction device 200. The air suction device 200 includes an air inlet 210, an air outlet 220 and an airway connecting the two, and a one-way air valve 300 is provided inside the airway. The one-way air valve 300 is used to control the one-way flow of the airflow to ensure that the air can be discharged from the sealing bag 100 without backflow. The air suction device 200 is fixed to the bag body of the sealing bag 100 through a sealing structure to ensure that the airway is completely connected to the air suction port 120 of the bag body and there is no air leakage.

[0052] The user puts a mobile phone or other device into the sealed bag 100, adjusts it to a suitable position, and seals the bag opening with the sealing strip 110. The user activates the vacuum device 200 by squeezing, manually pumping air, or other means, and the air passage in the vacuum device 200 exhausts air from the bag body through the air inlet 210 and the vacuum port 120. The one-way air valve 300 ensures that the air in the bag is discharged in one direction to prevent the outside air from flowing back into the bag body. When the air in the bag is exhausted, the bag body fits tightly against the surface of the device, while maintaining the stable sealing state of the sealing strip 110, completing the packaging of the vacuum waterproof bag.

[0053] By setting up a design that connects the vacuum device 200 to the sealing bag 100, the air in the bag can be quickly and thoroughly discharged to form a negative pressure environment. The use of the one-way air valve 300 ensures the one-way discharge of the airflow to avoid backflow affecting the sealing effect. The negative pressure state after vacuuming increases the fit between the sealing strip 110 and the bag body, significantly improves the waterproof performance of the bag body, and can adapt to deep water or high-pressure environments. The close fit between the bag body and the surface of the device eliminates the air gap, improves the touch screen sensitivity and operating feel, and is particularly suitable for underwater use. Users can operate the vacuum device 200 without additional tools, which is convenient and quick.

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

[0055] The air extraction chamber 400 is provided with a one-way air intake device covering the air intake port 210; wherein,

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

[0057] When the air extraction chamber 400 is reset, negative pressure is generated to extract air from the sealed bag 100 through the air inlet 210 and the air extraction port 120. In order to solve the problem that the air inside the waterproof bag cannot be efficiently removed, an air extraction device 200 based on the coordinated operation 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, the air is efficiently discharged from the sealed bag 100 to prevent the 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 extraction port 120 of the sealing bag 100 through the air inlet 210, and the other end is connected to the outside through the one-way air valve 300. The air extraction chamber 400 is made of a flexible material such as silicone or elastic plastic, and has good compressibility and durability. The one-way air inlet device is arranged inside the air extraction chamber 400, covering the air inlet 210, to ensure that air can only enter the air extraction chamber 400 from the sealing bag 100, and cannot flow back.

[0059] When the user presses the vacuum chamber 400, the air in the chamber is discharged along the one-way air valve 300, and the valve plate 500 automatically closes to prevent the outside air from flowing back into the sealing bag 100. When the user releases the pressing force, the vacuum chamber 400 returns to its original state under the action of the flexible material or the return spring 600, generating negative pressure, and the air in the sealing bag 100 is sucked into the vacuum chamber 400.

[0060] The user repeats the contraction and resetting actions many times to gradually exhaust the air in the sealing bag 100 until the bag fits the surface of the device.

[0061] The flexible design of the vacuum chamber 400 enables the air to be discharged from the sealed bag 100 quickly and efficiently, and the one-way air valve 300 is combined to prevent air backflow, thus realizing one-way control of the whole process. The vacuum operation is simple and intuitive, suitable for manual operation by users. The negative pressure environment can not only completely empty the air in the bag, but also improve the fit between the bag body and the sealing strip 110, thereby enhancing the waterproof performance of the bag body. The valve plate 500 design of the one-way air intake device ensures accurate control of the airflow direction, avoids air backflow, and has high reliability. Under negative pressure, the bag body fits tightly with the surface of the device, the touch screen sensitivity is significantly improved, and the operating feel is close to the bare metal experience. In underwater or wet hand environments, the touch screen operation is smooth and lag-free, and the user experience is better. The design of the vacuum chamber 400 is simple, and it can be flexibly adapted to sealed bags 100 of different sizes and shapes to meet the waterproof requirements of a variety of devices. It is particularly suitable for dynamic scenes such as water parks, diving and outdoor shooting, which improves the safety and convenience of operation of the equipment. The design of the air extraction chamber 400 and the one-way air valve 300 avoids a complex mechanical structure and realizes a stable and efficient air extraction function through simple physical principles. This design solves the problem that the existing waterproof bag cannot be vented and has poor sealing performance. It is suitable for a variety of high-end user groups and has broad market prospects.

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

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

[0064] When the vacuum chamber 400 is reset, the valve plate 500 is separated from the air inlet 210 under the action of negative pressure to allow air to pass through. The one-way air inlet device adopts the valve plate 500 structure, and its core function is to control the one-way flow of air by covering and leaving the air inlet 210. Compared with the traditional air valve, the design of the valve plate 500 is simpler and more flexible, and has higher reliability and adaptability, which can meet the needs of the vacuum chamber 400 and optimize the user experience.

[0065] The valve plate 500 covers the air inlet 210 and is made of a flexible material such as silicone, elastic plastic or composite material, and has excellent flexibility and durability. The size of the valve plate 500 is larger than the air inlet 210 to ensure full coverage during sealing without air leakage.

[0066] When the vacuum chamber 400 is compressed by the user, the air 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 is pressed against the air inlet 210 under pressure to form a reliable seal to prevent the outside air from flowing back to the sealing bag 100 through the air inlet 210.

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

[0068] The valve plate 500 has a relatively simple structure and does not require complex mechanical components or processing technology. It can be produced only by high-precision mold molding, which reduces the manufacturing cost. The connection between the valve plate 500 and the air inlet 210 does not require an additional fixing device, which is easy to install and has high assembly efficiency. The valve plate 500 is made of flexible material and can fit tightly with the air inlet 210 under pressure to achieve efficient sealing. Even in long-term use or high-pressure environments, the durability and deformation resistance of the flexible material make its sealing performance stable. The valve plate 500 is made of light and thin material and has a fast response speed. It can quickly complete the opening and closing action as the pressure of the exhaust chamber 400 changes, ensuring the timeliness of airflow control. The fitting and separation actions with the air inlet 210 rely on simple physical forces, without the need for additional mechanical drive, avoiding failures or delays caused by complex structures. The light and thin design of the valve plate 500 has less resistance to airflow, especially under the negative pressure suction effect during resetting, the air can quickly pass through the air inlet 210, significantly improving the exhaust efficiency. Compared with the traditional gas valve, the valve plate 500 does not require complicated moving parts, and has lower material cost and production cost.

[0069] In this embodiment, a reset spring 600 is provided in the vacuum chamber 400, and the reset spring 600 is used to drive the vacuum chamber 400 to reset. The reset spring 600 is provided in the vacuum chamber 400, and is intended to realize the rapid rebound reset of the vacuum chamber 400 after each compression through the elastic reset ability of the spring, thereby forming a negative pressure in the chamber and continuously extracting the air in the sealing 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 vacuum device 200.

[0070] When the user applies external force to the vacuum chamber 400, the air in the chamber is discharged through the one-way air valve 300, and the return spring 600 is compressed to store elastic potential energy. After the external force is released, the return spring 600 uses elastic potential energy to drive the chamber to return to its original state. Negative pressure is formed during the chamber reset process, thereby sucking the air in the sealing bag 100 and completing a cycle of the vacuum process. Through multiple compression and reset operations, the user uses the elastic recovery ability of the return spring 600 to continuously extract the air in the sealing bag 100 until the air is exhausted.

[0071] The addition of the reset spring 600 enables the vacuum chamber 400 to automatically reset after each compression, without the need for the user to pull the chamber back to its original position, making the operation simpler and more efficient. The spring reset process generates a stable negative pressure, ensuring that the chamber can continuously absorb the air in the sealed bag 100, and the exhaust efficiency is higher. The mechanical properties of the spring are stable, and can maintain the reset function of the chamber for a long time, significantly extending the service life of the vacuum device 200. Through the rapid recovery ability of the reset spring 600, the user can perform continuous vacuuming operations at a higher frequency, significantly shortening the exhaust time.

[0072] In this embodiment, a limiting boss 410 for fixing the return spring 600 is provided at the top of the air extraction chamber 400, and the limiting boss 410 is located in the top circle of the return spring 600, and the bottom circle of the return spring 600 presses the valve plate 500. In order to ensure that the return spring 600 can operate stably in the air extraction chamber 400, a limiting boss 410 structure for fixing the return spring 600 is designed. This structure fixes the top circle of the return spring 600 to the top of the air extraction chamber 400, and at the same time allows the bottom circle to press the valve plate 500, so that the return spring 600 can provide a return elastic force and effectively maintain the sealing state of the valve plate 500, thereby ensuring the efficient operation of the air extraction device 200.

[0073] The limiting boss 410 is located at the top of the vacuum chamber 400. The boss has a moderate height and a diameter that matches the top ring of the return spring 600, ensuring that the spring can be securely mounted on the boss. The limiting boss 410 prevents the return spring 600 from deflecting, slipping or failing during use through mechanical limiting, thereby maintaining the axial force state of the return spring 600. The top ring of the return spring 600 is nested on the outer edge of the limiting boss 410, and the boss serves as a fixed point to ensure that the spring maintains a stable position during operation. The bottom ring of the return spring 600 directly presses the valve plate 500 located at the bottom of the vacuum chamber 400, providing appropriate downward pressure so that the valve plate 500 is close to the air inlet 210 in the non-working state, thereby ensuring the sealing of the air inlet 210.

[0074] When the vacuum chamber 400 is compressed, the return spring 600 is compressed at the same time, and the limiting boss 410 limits the movement of the top circle of the spring, and the spring maintains axial force. At this time, the valve plate 500 is close to the air inlet 210 due to the positive pressure in the chamber, completing the sealing. When the external force is released, the return spring 600 pushes the vacuum chamber 400 to reset under the elastic action, and negative pressure is formed in the chamber. The bottom circle pressure is reduced, the valve plate 500 is sucked away from the air inlet 210, and the air in the sealing bag 100 enters the chamber through the air inlet 210. Through the fixing effect of the limiting boss 410, the return spring 600 maintains a stable position during repeated compression and reset actions, ensuring the working efficiency and reliability of the entire device.

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

[0076] In this embodiment, a sealing cover 700 is provided at the gas outlet 220;

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

[0078] When air is discharged from the airway, the airflow lifts up the sealing cover 700 and separates it from the limiting window to allow the airflow to overflow to the outside;

[0079] When air is discharged from the airway, the elastic member applies a pre-tightening force to make the sealing cover 700 cover the limiting window to form a seal.

[0080] In order to ensure that the air outlet 220 of the air extraction device 200 can work reliably both when the airflow is discharged and when it is stationary, a sealing structure consisting of a sealing cover 700, a limiting window and an elastic member is designed. This design can realize that the air outlet 220 is automatically opened when the airflow is discharged and restored to a sealed state when it is stationary, which not only ensures the smooth discharge of the airflow, but also effectively prevents the outside air or moisture from flowing back into the device through the air outlet 220.

[0081] The sealing cover 700 is located on the outer side of the air outlet 220 and is used to cover the air holes of the limiting window in a static state to form a seal. The sealing cover 700 is usually made of a hard or flexible material and has a high sealing performance. The limiting window is arranged at the air outlet 220 and has a plurality of air holes to allow air flow to pass through. When the air flow is discharged, the sealing cover 700 is lifted up, and the limiting window plays a role of support and diversion. An elastic member such as a spring or a flexible rubber column connects the sealing cover 700 and one side of the limiting window to provide a pre-tightening force for the sealing cover 700. When there is no air flow discharged, the elastic member makes the sealing cover 700 close to the limiting window to maintain a sealed state.

[0082] When the air extraction chamber 400 is compressed, the airflow pressure in the airway increases, and the airflow is discharged outward from the air outlet 220. The airflow lifts up the sealing cover 700, separating it from the limiting window, opening the air outlet channel, and the airflow overflows to the outside through the air holes of the limiting window. When the airflow in the airway stops, the pre-tightening force of the elastic member causes the sealing cover 700 to automatically return to the surface of the limiting window, covering the air holes, forming an airtight seal, and preventing the backflow of external air or moisture.

[0083] The sealing cover 700 can be opened automatically under the action of the airflow to complete the discharge of the airflow; when the airflow stops, it is automatically closed under the action of the elastic member to maintain the sealed state of the air outlet 220. The cooperation between the sealing cover 700 and the elastic member ensures that the air outlet 220 is completely sealed when stationary, effectively preventing external air or moisture from flowing back through the air outlet 220 to the inside of the air extraction device 200 or the sealing bag 100. The elastic member provides a stable pre-tightening force to ensure that the sealing cover 700 switches smoothly between the sealed and open states, reducing the wear of mechanical parts and enhancing the service life of the device. The support of the limit window to the sealing cover 700 prevents it from shaking or deflecting during the exhaust process, ensuring the stability of the structure.

[0084] In this embodiment, the elastic member is an elastic rubber column 710, and the rubber column is integrally formed with the sealing cover 700. The elastic member is in the form of an elastic rubber column 710, and is integrally formed with the sealing cover 700. This design improves the reliability and sealing performance of the overall device by reducing the number of components, simplifying the structure and assembly process, while reducing the production cost and manufacturing complexity, making it particularly suitable for efficient production and long-term use of the portable air extraction device 200.

[0085] The elastic rubber column 710 and the sealing cover 700 are integrally formed by a mold, and the rubber column and the sealing cover 700 are manufactured as a whole, eliminating the connection link of traditional independent components. The rubber column provides a pre-tightening force for the sealing cover 700 through its elastic performance, so that the sealing cover 700 can quickly return to the sealing position after the airflow stops.

[0086] When the vacuum chamber 400 is compressed, the airflow pressure lifts the sealing cover 700, and the rubber column is stretched, allowing the airflow to be discharged through the air holes of the limit window. When the airflow stops, the elastic restoring force of the rubber column drives the sealing cover 700 back to its original position, close to the surface of the limit window, and forms a reliable seal.

[0087] The one-piece design makes the elastic part and the sealing cover 700 an integral whole, without the need for additional connecting or fixing parts, which significantly simplifies the product structure. Reducing the number of parts reduces the cost of mold manufacturing and assembly, and improves production efficiency. The highly elastic material of the rubber column can provide a stable preload force to ensure that the sealing cover 700 is close to the surface of the limit window when stationary, forming a reliable airtight closure. The one-piece design eliminates the micro-leakage problem that may be caused by the connection of multiple parts and improves the stability of the sealing performance.

[0088] In this embodiment, a dam 800 is provided on the side of the air inlet 210 facing the air extraction, and a notch 810 is provided on the dam 800. The dam 800 is arranged on the outside of the bag body, and its main function is to prevent the two layers inside the bag body from being completely fitted together by forming an uneven structural area, thereby preventing the air extraction port 120 from being sealed. The combined design of the dam 800 and the notch 810 interferes with the fitting shape of the bag body, so that the air flow can smoothly pass through the air extraction port 120 and enter the air extraction device 200 during the air extraction process. Compared with the traditional isolation method, this design directly acts on the outer structure of the bag body, which 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 to the air inlet 210 of the air extraction device 200. The dam 800 forms a bulge around the air extraction port 120, in a closed loop or partially encircled form. The dam 800 itself is higher than the surface of the bag body, and its bulge increases the unevenness of the external structure of the bag body. One or more notches 810 are provided on the dam 800. The position and number of the notches 810 are designed according to the air flow requirements. The notches 810 are consistent with the air extraction direction and are used to guide the air flow.

[0090] The dam 800 forms a local uneven area with the inside and outside of the bag body through its convex shape, preventing the two layers inside the bag body from completely fitting together in the air extraction port 120 area. The notch 810 provides a clear airflow guide, allowing the airflow to smoothly enter the air extraction port 120 through the concave-convex area without being blocked by the bag body fitting together. When the air extraction device 200 is fixed to the dam 800 area by adhesive sealing, the air inlet 210 of the air extraction device 200 is connected to the air extraction port 120 of the bag body, and the air is smoothly discharged through the notch 810 of the dam 800 and the uneven area inside the bag body.

[0091] The coordinated design of the dam 800 and the notch 810 effectively prevents the two layers inside the bag from being attached to the air extraction port 120 by changing the external structural form of the bag body, thereby solving the problem of airflow blockage caused by the attachment. The concave and convex area destroys the sealing state formed by the attachment of the bag body, thereby ensuring the stability and efficiency of the air extraction process. The notch 810 of the dam 800 provides a clear airflow channel, ensuring that the air can be discharged smoothly through the air extraction port 120 regardless of how the negative pressure inside the bag body changes.

[0092] In this embodiment, a sealing sleeve 900 is also included. The sealing sleeve 900 is sleeved outside the air extraction device 200, and the sealing sleeve 900 wraps the air extraction device 200 and the bag opening of the sealing bag 100. In order to further enhance the connection sealing between the air extraction device 200 and the bag opening of the sealing bag 100, a sealing sleeve 900 is designed. The sealing sleeve 900 is wrapped around the outside of the air extraction device 200 and covers the bag opening of the sealing bag 100 to provide additional sealing protection. Through this design, not only the waterproof performance of the device can be enhanced, but also the fixing strength between the device and the bag body can be improved, ensuring the stability and safety of the air extraction process.

[0093] The sealing sleeve 900 achieves double sealing protection by covering the bag opening and the vacuum device 200, thereby significantly improving the overall waterproof performance of the device.

[0094] In this embodiment, the sealing sleeve 900 is made of elastic material. The sealing sleeve 900 is made of elastic material, and through its flexibility and resilience, it can fit tightly with the bag body and the air extraction device 200 to form a reliable sealing structure. The design of the elastic material can adapt to the changes in the shape of the bag body and the air extraction device 200, and at the same time has good durability and waterproof performance. This material selection simplifies the installation and disassembly process of the device, and at the same time enhances the environmental adaptability and user experience of the sealing sleeve 900.

[0095] The present invention is a vacuum waterproof bag, which aims to solve the problems of traditional waterproof bags, such as the inability to discharge air, poor operating feel, excessive buoyancy, and unreliable sealing performance. Through a number of innovative designs and structural optimizations, the product achieves functions such as vacuum sealing, efficient air discharge, and convenient and stable operation. Its comprehensive design not only improves the performance of the waterproof bag, but also significantly improves the user experience and meets the needs of various usage scenarios.

[0096] The air extraction device 200 is fixed to the bag body by gluing and sealing, and has stable sealing and efficient exhaust capacity. It is equipped with a one-way air valve 300 and an air extraction chamber 400, and through the mechanical compression and reset operation of the chamber, the air in the bag body is discharged in one direction to prevent the backflow of external air.

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

[0098] The sealing sleeve 900 is made of elastic material, and wraps the exhaust device 200 and the bag opening to achieve double sealing protection, effectively preventing moisture and gas from penetrating. The dam 800 structure is arranged on the outside of the bag body, and the protrusions and notches 810 cooperate to prevent the inside and outside of the bag body from fitting together to form a closed space, ensuring smooth discharge of air.

[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 applying a pre-tightening force through an elastic member to ensure that the air flow is unobstructed when discharged and a reliable seal is formed when stationary.

[0100] The one-way air intake device adopts a valve plate 500 structure, which is light and efficient, and can be automatically opened and closed by airflow to ensure one-way discharge of gas. It has a simple structure and low cost.

[0101] The design of the vacuum chamber 400 and the one-way air valve 300 form a stable and reliable air removal mechanism to ensure that the air in the bag can be quickly and thoroughly discharged. After the air is pumped out, the bag fits tightly to the surface of the device, the touch sensitivity is significantly improved, and the operating feel is close to the bare metal experience. There is no air residue or bubble interference in the bag, the light refraction is reduced, and the underwater shooting effect is clearer.

[0102] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
