[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] like Figures 1-6 As shown, this utility model provides an inflatable inner pillow for handbags, including an airbag 1. The airbag 1 is fixedly connected to an inflation device 2, which includes a pressure ball 3 and a valve assembly 4. The pressure ball 3 is connected to the valve assembly 4 via a conduit 5. The valve assembly 4 includes two one-way valves 6. Each one-way valve 6 includes an outer shell 7, a movable part 8, and a valve plate 9. The outer shell 7 has a partition 10, which has an assembly hole 11 and a ventilation hole 12. The movable part 8 is movably installed in the assembly hole 11, and the valve plate 9 is fixedly installed in the movable part 8. The movable part 8 elastically abuts against the partition 10 via a spring 13. The movable part 8 is fixedly installed to the valve plate 9 via a fixing part 14, which has a protrusion 15. The valve plate 9 is made of soft silicone. The valve assembly 4 is fixedly connected to a cover 17 via a connector 16.

[0022] Through the above technical solution, the airbag 1 of this utility model is equipped with an inflation device 2. When in use, the airbag 1 is placed inside the handbag, and then the airbag 1 is inflated by the inflation device 2, so that the airbag 1 is filled with air inside the handbag, providing support for the handbag and preventing the handbag from collapsing and deforming.

[0023] Example 2:

[0024] like Figures 1-6 As shown, the airbag 1 of this invention is a soft, foldable, sealed container, its shape adapted to the internal space of the handbag. An inflation device 2 is fixedly connected to the airbag 1, used to inflate or deflate the airbag 1. The inflation device 2 includes two main parts: a pressure ball 3 and a valve assembly 4. The pressure ball 3 is a hollow sphere made of elastic material. The valve assembly 4 includes an air inlet and an air outlet. The pressure ball 3 is connected to the valve assembly 4 via a conduit 5. In use, the airbag 1 is placed inside the handbag, and the pressure ball 3 is squeezed. Air enters the valve assembly 4 through the conduit 5 and is then delivered into the airbag 1. Repeatedly squeezing the pressure ball 3 causes the airbag 1 to gradually inflate until it fills the internal space of the handbag. After inflation, the airbag 1 maintains its shape, providing support for the handbag. When it needs to be stored, the deflation function on the valve assembly 4 is opened, the air inside the airbag 1 is expelled, and the airbag 1 returns to its flat state for easy removal and storage. This design allows users to flexibly adjust the inflation level to achieve optimal support for different handbag sizes and shapes. The inflatable inner pillow effectively prevents deformation and collapse during long-term storage, extending the handbag's lifespan. Furthermore, the inflatable inner pillow itself is small and lightweight, making it convenient to carry and use. In addition, because it uses air as the support medium, it does not place any extra burden on the handbag and will not affect its appearance due to compression or deformation. This inflatable inner pillow provides a simple and practical solution for handbag maintenance and storage.

[0025] Example 3:

[0026] like Figures 1-6As shown, the valve assembly 4 of this utility model includes two one-way valves 6. These two one-way valves 6 are an inlet valve and an outlet valve, respectively, and are arranged in series. This design allows the airbag 1 to exhaust by simply pressing the first one-way valve 6. The first one-way valve 6 acts on the second one-way valve 6, causing both one-way valves 6 to open simultaneously, completing the airbag 1's exhaust process. The two one-way valves 6 have the same structure but operate in opposite directions. The inlet valve only allows air to enter the airbag 1 from the outside, while the outlet valve only allows air to exit from the inside of the airbag 1. The one-way valve 6 consists of a valve seat, a valve core, and a spring 13. The valve seat is cylindrical and hollow inside, with one end connected to the airbag 1 and the other end connected to the outside atmosphere. The valve core is installed inside the valve seat and can move freely within it. The spring 13 is installed between the valve core and the valve seat, keeping the valve core in a closed state. When the airflow direction is consistent with the valve's allowed direction, the airflow pressure overcomes the force of the spring 13, pushing the valve core to move, opening the valve, and allowing gas to pass through. When the airflow direction is reversed, the combined force of spring 13 and airflow pressure causes the valve core to press tightly against the valve seat, closing the valve and preventing gas from passing through. During use, the airflow generated by squeezing the pressure ball 3 enters the air inlet valve through the conduit 5. The airflow pressure opens the air inlet valve, allowing air to enter the airbag 1. After releasing the pressure ball 3, the air inlet valve automatically closes under the action of spring 13, preventing air backflow. When deflation is required, pressing the valve core of the outlet valve overcomes the force of spring 13, opening the valve and expelling the air from the airbag 1. After releasing, the outlet valve automatically closes under the action of spring 13. This dual one-way valve design ensures that the inflation and deflation processes of the airbag 1 can be independently controlled, making operation simple and convenient. Simultaneously, the combined use of the two one-way valves 6 effectively prevents air leakage from the airbag 1 during use, ensuring the long-term stability of the inflatable inner pillow.

[0027] Example 4:

[0028] like Figures 1-6As shown, the one-way valve 6 of this utility model includes an outer shell 7, a movable component 8, and a valve plate 9. The outer shell 7 has a cylindrical structure, with one end connected to the airbag 1 and the other end connected to the conduit 5 or the outside atmosphere. A partition 10 is provided inside the outer shell 7, dividing the space of the outer shell 7 into upper and lower chambers. A circular mounting hole 11 and multiple smaller ventilation holes 12 are opened on the partition 10. The mounting hole 11 is located in the center of the partition 10 and is used to install the movable component 8. The ventilation holes 12 are evenly distributed around the mounting hole 11 for gas passage. The movable component 8 is cylindrical, with a diameter slightly smaller than the mounting hole 11, and can slide freely within the mounting hole 11. The upper end of the movable component 8 extends into the upper chamber, and the lower end extends into the lower chamber. A circular valve plate 9 is fixedly installed at the lower end of the movable component 8. The valve plate 9 has a diameter larger than the mounting hole 11 and can completely cover the mounting hole 11 and the ventilation holes 12. The valve plate 9 is made of a flexible material and can fit tightly against the lower surface of the partition 10. A compression spring 13 is installed between the movable part 8 and the partition 10. One end of the spring 13 is fixed to the partition 10, and the other end elastically abuts against the movable part 8. The function of the spring 13 is to maintain downward pressure on the movable part 8, causing the valve plate 9 to press tightly against the lower surface of the partition 10, thus closing the vent 12. When the air pressure in the upper chamber of the outer casing 7 is greater than that in the lower chamber, the pressure difference will push the movable part 8 upward, compressing the spring 13. The valve plate 9 will then lift off the surface of the partition 10, opening the vent 12. Gas can then flow from the upper chamber to the lower chamber. When the air pressure in the upper chamber is less than or equal to that in the lower chamber, the spring 13 pushes the movable part 8 downward, causing the valve plate 9 to re-press against the surface of the partition 10, closing the vent 12 and preventing backflow of gas.

[0029] Example 5:

[0030] like Figures 1-6As shown, the one-way valve 6 of this utility model includes a housing 7, a movable component 8, and a valve plate 9. The housing 7 is cylindrical, with one end connected to the airbag 1 and the other end connected to the conduit 5 or the outside. A partition 10 is provided inside the housing 7, dividing the space into upper and lower chambers. A circular mounting hole 11 is provided in the center of the partition 10, with multiple smaller ventilation holes 12 evenly distributed around it. The movable component 8 is cylindrical, with a diameter slightly smaller than the mounting hole 11, allowing it to slide freely within the mounting hole 11. The upper end of the movable component 8 extends into the upper chamber, and the lower end extends into the lower chamber, with a circular valve plate 9 fixedly installed at the lower end. The valve plate 9 has a diameter larger than the partition 10, completely covering the mounting hole 11 and the ventilation holes 12. The movable component 8 is fixedly connected to the valve plate 9 via a fixing component 14, which has a protrusion 15. The protrusion 15 extends outward parallel to the surface of the valve plate 9, near the periphery of the valve plate 9. A compression spring 13 is installed between the movable part 8 and the partition 10. One end of the spring 13 is fixed to the partition 10, and the other end contacts the movable part 8. The spring 13 provides downward pressure to the movable part 8, causing the valve plate 9 to press tightly against the lower surface of the partition 10, sealing the vent 12. When the air pressure in the upper chamber is greater than that in the lower chamber, the pressure difference pushes the movable part 8 upward, compressing the spring 13. The valve plate 9 then lifts up, opening the vent 12, and gas flows from the upper chamber to the lower chamber. During this process, the protrusion 15 on the fixed part 14 provides support, preventing excessive deformation of the central area of ​​the valve plate 9 due to air pressure. The presence of the protrusion 15 keeps the valve plate 9 relatively flat under air pressure, preventing the central area of ​​the valve plate 9 from concave deformation, which would affect the sealing effect.

[0031] Example 6:

[0032] like Figures 1-6As shown, the one-way valve 6 of this utility model includes a housing 7, a movable component 8, and a valve plate 9. The housing 7 is cylindrical, with one end connected to the airbag 1 and the other end communicating with the conduit 5 or the external environment. A partition 10 is provided inside the housing 7, dividing the space into upper and lower chambers. A circular mounting hole 11 is located in the center of the partition 10, surrounded by multiple smaller ventilation holes 12 evenly distributed around it. The movable component 8 is cylindrical, with a diameter slightly smaller than the mounting hole 11, allowing it to slide freely within it. The upper end of the movable component 8 extends into the upper chamber, and the lower end extends into the lower chamber, with a circular valve plate 9 installed at the lower end. In this embodiment, the valve plate 9 is made of soft silicone. Soft silicone is a material with excellent physical properties, suitable for use as the valve plate material. Soft silicone has good elasticity, can deform under pressure, and quickly return to its original shape after the pressure is removed. This characteristic allows the valve plate 9 to tightly adhere to the surface of the partition 10, forming an effective seal. Meanwhile, the elasticity of soft silicone allows valve plate 9 to respond quickly to pressure changes when opened, improving the sensitivity and efficiency of check valve 6. Soft silicone also possesses excellent durability and fatigue resistance. Under long-term, repeated opening and closing conditions, soft silicone valve plate 9 maintains stable physical properties and is not prone to permanent deformation or material fatigue. This ensures that check valve 6 maintains good sealing performance and working efficiency during long-term use. Furthermore, soft silicone has excellent chemical stability, resisting the erosion of various chemicals and is not prone to aging or degradation, extending the service life of valve plate 9. Another advantage of soft silicone is its good temperature adaptability. Over a wide temperature range, soft silicone maintains stable physical properties and its elasticity and sealing performance are not significantly affected by temperature changes. This allows the inflatable inner pillow for handbags to be used normally under different ambient temperatures, improving the product's applicability. In actual use, soft silicone valve plate 9 exhibits excellent sealing performance. When check valve 6 is closed, soft silicone valve plate 9 can tightly adhere to the surface of partition 10, effectively preventing gas from passing through. Even under minute pressure differences, the elastic properties of the soft silicone ensure good contact between the valve plate 9 and the partition 10, preventing air leakage. When the one-way valve 6 opens, the soft silicone valve plate 9 can deform rapidly, allowing gas to pass through smoothly while maintaining sufficient strength to prevent damage from airflow impact.

[0033] Example 7:

[0034] like Figures 1-6As shown, the valve assembly 4 of this utility model includes an inlet valve and an outlet valve, with two one-way valves 6 arranged in series. The valve assembly 4 is fixedly connected to the cover 17 via a connector 16. The connector 16 is made of flexible material, with one end firmly connected to the valve assembly 4 and the other end connected to the cover 17. The flexible design of the connector 16 allows the cover 17 to rotate and shift relative to the valve assembly 4 to a certain extent, facilitating operation. The cover 17 is disc-shaped, with a diameter slightly larger than the outer diameter of the valve assembly 4 and a moderate thickness to ensure sufficient strength. The inner surface of the cover 17 has a groove that matches the shape of the valve assembly 4 to accommodate the upper structure of the valve assembly 4. The depth of the groove is slightly less than the protrusion height of the valve assembly 4, ensuring that the cover 17 remains flush with the surface of the airbag 1 when closed. The edge of the cover 17 has a downwardly extending annular flange, the inner side of which forms an interference fit with the outer wall of the valve assembly 4, providing additional sealing effect. The upper surface of the cover 17 is designed with a smooth arc shape to reduce friction with external objects and prevent accidental opening. The cover 17 has small protrusions on its edge for easy gripping and opening with fingers. Made of hard plastic, the cover 17 possesses sufficient strength and toughness to withstand various external forces during daily use, protecting the internal valve assembly 4. The cover 17 and valve assembly 4 are connected by a snap-fit ​​mechanism. The outer wall of the valve assembly 4 has an annular protrusion, and a corresponding groove is provided on the inner side of the cover 17. When the cover 17 is fastened onto the valve assembly 4, the protrusion engages with the groove, forming a secure lock. This design ensures both the stability of the cover 17 and ease of opening. The snap-fit ​​structure is carefully designed, requiring moderate force to open without being too difficult, while preventing accidental loosening. A sealing ring is provided on the surface of the cover 17 that contacts the valve assembly 4. Made of elastic material, the sealing ring is embedded in the annular groove on the inner side of the cover 17. When the cover 17 is closed, the sealing ring fits tightly against the upper surface of the valve assembly 4, forming a reliable seal. The material and size of the sealing ring have been optimized to ensure a good seal without increasing resistance when opening the cover 17. The cover 17 is designed with dust prevention in mind. When closed, the cover 17 completely covers the exposed portion of the valve assembly 4, preventing dust, moisture, and other impurities from entering the valve. The transition between the edge of the cover 17 and the surface of the airbag 1 is beveled to prevent dust accumulation at the edges. In actual use, after inflating the airbag 1, the user simply needs to fasten the cover 17 onto the valve assembly 4. The latching structure of the cover 17 will emit a clear click, indicating that the cover 17 is correctly locked. The presence of the cover 17 significantly improves the sealing performance of the valve assembly 4, reducing the possibility of slow leakage during long-term storage. Simultaneously, the cover 17 also protects the valve assembly 4, preventing accidental opening due to external pressure or impact. When it is necessary to deflate the airbag 1, the user can easily lift the cover 17 to expose the valve assembly 4. The cover 17 is connected to the valve assembly 4 via the connector 16 and will not be separated from the valve assembly 4, thus avoiding the risk of loss.After deflating, simply replace the cover 17 to restore the seal. The addition of cover 17 not only improves the sealing performance of the inflatable inner pillow in the handbag but also enhances the overall aesthetics and texture of the product.
