Description

Technical Field

[0001] This utility model relates to an air valve, specifically to a detachable air valve and a filling product containing the air valve. Background Technology

[0002] Air valves are widely used in daily life, including sleeping mats, pillows, beanbag chairs, swimming rings, and vacuum storage bags. These products can selectively fill or expel air through the air valve, and can be used after closing the valve. When not in use, simply opening the valve will expel the air or contents, allowing the product to be folded up to reduce its size and save space.

[0003] However, most existing air valves cannot be disassembled within the product. With prolonged use, leaks often occur due to damage to internal parts, rendering the entire product unusable and resulting in significant resource waste. Furthermore, in situations requiring the insertion or removal of contents, the product is often limited by the valve structure and cannot be disassembled. This necessitates adding additional openings, increasing manufacturing processes and costs, and increasing the risk to airtightness. Clearly, the existing air valve structure is not ideal and requires improvement. Utility Model Content

[0004] To address the shortcomings of the aforementioned air valve structure, such as the inability to disassemble and replace parts or perform repairs in case of failure, this utility model provides an air valve comprising a hollow ring-shaped fixing member, including a fixing ring plate extending radially from an outer ring wall of the fixing member, the fixing ring plate being used to engage with the bag body; a venting member axially passing through the fixing member and detachably engaging with the fixing member outside the bag body, the venting member being groove-like and defining a first space therein, the venting member being adjacent to a closed end of the fixing member. The device includes a retaining wall and a perforation through the retaining wall, with a perforated annular wall extending axially from the retaining wall toward the first space around the perforation; a check plug disposed in the perforation, with one end including a check spring, the check spring being positioned in the first space and abutting against the end of the perforated annular wall to close the perforation, the check spring being used to receive a suction force and flip toward the first space to allow the perforation to communicate with the first space; and a valve cover detachably connected to the venting device and closing the first space.

[0005] The device includes a ring-shaped blocking neck protruding within the perforated ring wall, the diameter of which is smaller than the diameter formed by the perforation and / or the perforated ring wall; two ends of a check plug protruding from the sides of the blocking neck, the end of the check plug opposite the check spring containing a abutment portion, the abutment portion abutting against the other side of the blocking neck opposite the first space, the blocking neck being closed by the abutment portion; and an air passage penetrating between the blocking wall and the perforated ring wall, the two air vents at both ends of the air passage being located at the perforated ring wall and the blocking wall, respectively.

[0006] The valve cover includes a valve ring wall that extends annularly from one inner side of the valve cover. When the valve cover is combined with the venting member, the valve ring wall and the perforated ring wall are axially aligned, so that the two sides of the anti-reverse spring are respectively abutted by the valve ring wall and the perforated ring wall.

[0007] The surface of the retaining wall is recessed with a movable groove for engaging with the tool head of an existing tool wrench.

[0008] This utility model also provides a filling article comprising a soft bag body with an opening extending through any part of the bag body, the opening being provided with the air valve provided in the preceding paragraph.

[0009] The bag contains a filler material whose volume is smaller than the aperture of the fastener but larger than the aperture of the vent.

[0010] In use, the valve cover is removed to extract air from the filling product. When the valve cover is removed, the abutting part of the check plug continues to abut against the stop neck, so the check plug will not be displaced or fall off the vent due to the removal of the valve cover, and the check spring continues to close the perforation, so gas will not flow into or out of the filling product through the perforation.

[0011] Next, a vacuum nozzle is connected to the vent and covers the first space. When the vacuum nozzle generates suction, the anti-reverse spring is flipped up due to the suction, allowing airflow to enter the vent, the perforation, and the first space through the opening located on the barrier wall in sequence, and through the gap between the anti-reverse spring and the perforation ring wall. This allows the vacuum nozzle to extract gas from the filling product, thereby reducing the volume.

[0012] When in use, the venting component can be removed to fill the filling product with gas. The larger diameter of the fixing component allows the filling product to be inflated quickly, which is different from the shortcomings of the existing inflation device where a two-way air valve restricts the flow of gas, resulting in a long inflation time.

[0013] The filling product provided by this utility model can also achieve the function of filling or replacing the filling material through the setting of the air valve. The larger diameter of the fixing member allows filling material larger than the air vent to be filled into or discharged from the bag body of the filling product. This differs from existing filling products (such as beanbag chairs) which are often discarded directly after long-term use because their filling material (such as foam or foam balls) deforms or loses its support, resulting in resource waste.

[0014] The filling product provided by this utility model can be adjusted according to needs through the air valve to exhibit multi-purpose functions. For example, after being filled with the filling material, the filling product can be used as a beanbag chair, allowing the user to softly shape it according to their sitting or lying needs; after being inflated, the filling product can be used as an inflatable cushion to provide support for the user; when the filling material is filled and a vacuum is applied, the filling product will harden and be shaped into any shape according to the vacuum, and its firmness will change according to the degree of vacuum, allowing the user to shape it according to their body contours. This allows the filling product provided by this utility model to achieve repeated shaping and switch between firm and soft states through the air valve. Attached Figure Description

[0057] Please refer to Figure 1 as well as Figure 2 This is a first preferred embodiment of the air valve provided by the present invention, comprising a fixing member 10, a venting member 20, a check plug 30, and an air valve cover 40. The fixing member 10 is a hollow ring shape, and includes a fixing ring plate 11 extending radially from an outer ring wall of the fixing member 10. The fixing ring plate 11 is used to engage with a filling article 50, and the method of engaging the fixing ring plate with the filling article 50 will be described in a later paragraph.

[0058] The venting element 20 is axially inserted into the fixing element 10 and is detachably connected to the fixing element 10. This detachable connection can be achieved through screws, pins, or structural protrusions and recesses. In this embodiment, the inner ring wall of the fixing element 10 is provided with a fixing thread 12, and the outer ring wall of the venting element 20 is provided with an external thread 26, allowing the venting element 20 to be screwed into the fixing thread 12 of the fixing element 10 via the external thread 26.

[0059] An air-blocking ring (O-Ring) can also be provided between the venting component 20 and the fixing component 10 to prevent gas leakage between the venting component 20 and the fixing component 10.

[0060] The vent 20 is groove-shaped and defines a first space 211, and includes a baffle wall 21, a perforation 22, a perforated annular wall 23, a baffle neck 24, and a ventilation channel 25.

[0061] The barrier wall 21 is formed at a closed end 201 of the vent 20, the perforation 22 axially penetrates the barrier wall 21, and the perforation annular wall 23 extends axially around the perforation 22 and protrudes from the barrier wall 21 toward the first space 211.

[0062] A ring-shaped protrusion of a stop neck 24 is provided within the perforated annular wall 23, such that the diameter defined by the stop neck 24 is smaller than the diameter formed by the perforation 22 and / or the perforated annular wall 23. The air passage 25 extends between the stop wall 21 and the perforated annular wall 23, and the two air vents 251 at both ends of the air passage 25 are respectively located within the perforated annular wall 23 and the stop wall 21.

[0063] The check plug 30 is generally rod-shaped and disposed within the perforation 22, with its two ends protruding from both sides of the abutment neck 24. That is, at least a portion of the outer diameter of the check plug 30 is smaller than the diameter formed by the abutment neck 24. Each end of the check plug 30 includes a check spring 31 and an abutment portion 32. The check spring 31 protrudes radially from one end of the check plug 30, and its minimum diameter is larger than the diameter formed by the perforation annular wall 23. The abutment portion 32 protrudes radially from the other end of the check plug 30 opposite the check spring 31, and its minimum diameter is larger than the diameter formed by the abutment neck 24.

[0064] like Figure 2 and Figure 3 As shown, in a first usage embodiment, when the valve is in a static state, the check plug 30 is disposed within the perforation 22 and the check spring 31 is positioned in the first space 211 and abuts against the end of the perforation ring wall 23. At this time, the perforation 22 is closed by the check spring 31; the abutment portion 32 abuts against the other side of the stop neck 24 opposite to the first space 211; the stop neck 24 is closed by the abutment portion 32. When a suction force is applied to the check spring towards the first space 211, an airflow can sequentially enter the air passage 25, the perforation 22, and the first space 211 through the vent 251 located on the stop wall 21, and through the gap between the check spring 31 and the perforation ring wall 23.

[0065] like Figure 7 As shown, in a second usage embodiment, when the valve is in a static state, the check plug 30 is disposed in the perforation 22 and the check spring 31 is opposite to the abutment 32. At this time, the abutment 32 is located in the first space 211 and abuts against and closes the blocking neck 24; the check spring 31 is located at the other end of the blocking neck 24 opposite to the first space 211 to close the perforation 22 and the air passage 25. When a thrust is applied to the check spring away from the first space 211, the airflow can sequentially enter the perforation 22 and the air passage 25 in the first space 211.

[0066] As shown in the above embodiments, the air valve provided by this utility model can determine the manner in which the check plug 30 is placed in the perforation 22 according to the requirements (airflow direction).

[0067] The anti-reverse spring 31 is made of a flexible material that can be concave or convex, and the flexible material may include silicone or rubber.

[0068] Preferably, the entire anti-reverse plug 30 is integrally molded from the elastic material.

[0069] The valve cover 40 is disc-shaped and detachably connected to the vent 20, sealing the first space 211. This detachable connection can be achieved through screws, pins, or structural irregularities. In this embodiment, the inner ring wall of the vent 20 has an internal thread 27, and the outer ring wall of the valve cover 40 has a valve thread 41, allowing the valve cover 40 to be screwed into the vent 20 through the valve thread 41 and the internal thread 27.

[0070] An O-ring can also be provided between the valve cover 40 and the vent 20 to prevent gas leakage between the valve cover 40 and the vent 20.

[0071] The valve cover 40 includes a valve annular wall 42 that extends annularly from an inner side 401 of the valve cover 40. When the valve cover 40 is engaged with the vent member 20, the valve annular wall 42 is axially aligned with the perforated annular wall 23. In this first usage embodiment, the two sides of the anti-reverse spring 31 are pressed against the valve annular wall 42 and the perforated annular wall 23 respectively to prevent gas from leaking out of the perforation 22.

[0072] Preferably, the valve cover 40 forms a knob 43 shape on the other side of the inner side 401 to facilitate the user's assembly or removal of the valve cover 40.

[0073] Please refer to Figure 2 as well as Figure 3 This utility model also provides a filling article 50 including the aforementioned air valve, the filling article 50 comprising a soft bag body 51. The material of the bag body 51 is not limited, and it can be a sealed bag body made of woven fabric or plastic film. An opening 52 extends through any part of the bag body 51 for mounting the fixing member 10 of the air valve. The fixing member 10 passes through the opening 52 and is fixed to one side of the fixing ring 11 by means of gluing or heat fusion. The fixing thread 12 of the fixing member 10 protrudes from the opening 52 outside the bag body 51, so that the venting member 20 can be engaged or disassembled with the fixing member 10 outside the bag body 51, and the air passage 25 is located at the air vent 251 of the abutment wall 21, which corresponds to the inside of the bag body 51.

[0074] The fixing ring 11 can optionally be combined with the inner surface 511 or the outer surface 512 of the bag body 51. In this embodiment, the fixing ring 11 is located inside the bag body 51 and is fixedly engaged with the inner surface 511 of the bag body 51.

[0075] When the venting component 20 is combined with the fixing component 10, the first space 211 faces outward from the bag body 51, so that the air valve cover 40 can be combined with or disassembled from the venting component 20 outside the bag body 51.

[0076] Please refer to Figure 3 When used in the first embodiment of this invention, the valve cover 40 can be removed to extract air from the filling product 50. When the valve cover 40 is removed, since the abutting portion 32 of the check plug 30 continues to abut against the blocking neck 24, the check plug 30 will not shift or fall onto the vent 20 due to the removal of the valve cover 40, and the check spring 31 continues to close the perforation 22, so gas will not flow into or out of the filling product 50 through the perforation 22.

[0077] Next, a vacuum nozzle B1 can be connected to the ventilation component 20 and cover the first space 211. When the vacuum nozzle B1 generates suction, the anti-reverse spring 31 flips up due to the suction, allowing airflow to enter the ventilation channel 25 and the perforation 22 sequentially through the ventilation port 251 located on the baffle wall 21, and enter the first space 211 through the gap between the anti-reverse spring 31 and the perforated ring wall 23. This allows the vacuum nozzle B to extract gas from the filling product 50, thereby achieving the effect of reducing volume.

[0078] Please refer to Figure 7 When used in the second embodiment of this invention, the valve cover 40 can be removed to fill the filling article 50 with air. When the valve cover 40 is removed, since the abutting part 32 of the check plug 30 continues to abut against the blocking neck 24, the check plug 30 will not be displaced or fall off the vent 20 due to the removal of the valve cover 40, and the check spring 31 continues to close the perforation 22, so gas will not flow into or out of the filling article 50 through the perforation 22.

[0079] Then as Figure 8 As shown, an inflation head B2 can be connected to the vent 20 and cover the first space 211. When the inflation head B2 inflates towards the first space 211, the anti-reverse spring 31 flips up and moves away from the first space 211 due to the thrust introduced by the airflow. At this time, the airflow can sequentially enter the perforation 22, the air passage 25, and the vent 251 in the first space 211, allowing the inflation head B2 to input gas into the filling product 50. In the above embodiment, by setting the anti-reverse plug 30 in the perforation 22, the air valve provided by the utility model can achieve the effect of a two-way air valve, and helps the user to controllably fill or remove gas from the filling product 50 according to needs, so as to avoid a large amount of gas suddenly rushing in and causing the filling product to expand and rupture.

[0080] Please refer to Figure 4In use, the venting component 20 can be removed to fill the filling product 50 with gas. The larger diameter of the fixing component 10 allows the filling product 50 to be inflated quickly, which is different from the disadvantage of the two-way air valve on the existing inflation device that restricts the flow of gas and results in a long inflation time. It can be applied to large-volume filling products 50 that require a large amount of gas filling.

[0081] The filling product 50 provided by this utility model can also achieve the function of filling or replacing a filling material 53 through the setting of the air valve. Through the larger diameter of the fixing member 10, the filling material 53, whose volume is smaller than the diameter of the fixing member 10 and larger than the diameter of the air vent 251, can be filled or discharged into the bag body 51 of the filling product 50. Unlike existing filling products (such as beanbag chairs), which are often discarded directly after long-term use because their filling materials (such as foam or foam balls) deform or lose support, resulting in resource waste.

[0082] In addition, the filling product 50 provided by this utility model can be adjusted according to needs to exhibit multi-purpose functions through the setting of the air valve. For example, after the filling material 53 is filled into the filling product 50, it can be used as a beanbag chair for users to softly shape according to their sitting or lying needs; after the filling product 50 is inflated, it can be used as an inflatable cushion to provide support for users; when the filling material 53 is filled into the filling product 50 and a vacuum is drawn, the filling product 50 will harden and be shaped into any shape according to the vacuum, and its firmness will change according to the degree of vacuum, so that users can shape it according to their body contours. This allows the filling product 50 provided by this utility model to achieve repeated shaping and switch between firm and soft states through the setting of the air valve.

[0083] Please refer to Figure 5 as well as Figure 6 This is the second preferred embodiment of the air valve provided by the present invention. The difference from the previous embodiment is that the air vent 20 has a corresponding moving groove 28 recessed on the surface of the abutment wall. The moving groove 28 is concave and convexly connected to the tool head B commonly used in existing tool wrenches (such as a polygonal socket or toothed socket for wrenches), so that the user can remove the air vent 20 from the fixing member 10.
