Description

Technical Field

[0001] This application relates to the field of valve technology, and in particular to a reversible cyclone inflation valve. Background Technology

[0002] An inflation valve is a valve used for inflating or deflating inflatable products, commonly used in swimming rings, air mattresses, inflatable tents, rubber boats, and other inflatable products. The function of an inflation valve is to control the entry and exit of gas into the inflatable product. During inflation, the inflation valve needs to be connected to a gas source, such as an air pump or compressor, and then air or gas is injected into the inflatable product through the inflation valve until the preset pressure or the required inflation volume is reached.

[0003] In related technologies, to prevent gas leakage from inflatable products, a rubber sheet is typically installed at the valve opening of the inflation valve. Under normal circumstances, the rubber sheet presses against the inflation valve, sealing the valve opening. During inflation, the gas entering the inflation valve pushes the rubber sheet open, allowing gas to be injected into the inflatable product through the valve opening. After inflation, the rubber sheet, under the pressure of the gas inside the inflatable product, presses back against the inflation valve, sealing the valve opening and preventing gas leakage. After the inflatable product is no longer in use, the inflation valve can be removed from the valve seat, and the inflatable product can be squeezed to expel the gas, reducing its volume and weight for easier storage and transport.

[0004] Regarding the aforementioned technologies, the inventors believe that during the process of removing the inflation valve and expelling gas by squeezing the inflatable product, since the inflation port of the inflatable product is fully open at this time, external air can easily enter the inflatable product through the valve seat, thereby reducing the efficiency of the exhaust process and making it difficult for the gas inside the inflatable product to be completely expelled. Summary of the Invention

[0005] In order to improve the problem that when inflatable products are vented, external air can easily enter the inflatable products, resulting in reduced venting efficiency and difficulty in completely venting the gas inside the inflatable products, this application provides a flip-up cyclone inflation valve.

[0006] The technical solution of the reversible filling and discharging cyclone air valve provided in this application is as follows:

[0007] A flip-up cyclone inflation valve includes an inflation valve body, an inflation valve seat, and a sealing valve plate disposed within the inflation valve body. The inflation valve body includes an outer valve ring, with fixing rings on both sides of the outer valve ring. A plurality of fixing protrusions are spaced apart on the inner walls of a pair of fixing rings. The inflation valve seat includes an inner valve seat tube, with a plurality of first fixing grooves spaced apart on the outer wall of the inner valve seat tube. The plurality of first fixing grooves correspond one-to-one with the plurality of fixing protrusions. A second fixing groove is formed on one side wall of each of the plurality of first fixing grooves, and the second fixing groove is adapted to the fixing protrusion.

[0008] By adopting the above technical solution, the fixing protrusion on the fixing ring is inserted into the first fixing groove, and the outer ring of the air valve is rotated so that the fixing protrusion is embedded in the second fixing groove, thus fixing the inflation valve body onto the inflation valve seat. Therefore, the orientation of the sealing valve plate can be adjusted by flipping the inflation valve body, so that the sealing valve plate can seal the inflation valve seat when the inflation product is inflated or deflated. Therefore, when the inflation product is deflated, external gas is not easy to enter the inflation product, improving the deflation efficiency and allowing the gas inside the inflation product to be discharged more completely.

[0009] Optionally, a limiting groove is provided on the side of the fixing protrusion facing away from the fixing ring; a limiting protrusion is provided on the groove wall of the second fixing groove corresponding to the limiting groove, and the limiting protrusion is adapted to the limiting groove.

[0010] By adopting the above technical solution, when the fixed protrusion is embedded in the second fixed groove, the limiting protrusion is adapted to be embedded in the limiting groove, thereby increasing the friction between the fixed protrusion and the wall of the second fixed groove, making it difficult for the fixed protrusion to slide out of the second fixed groove, thus improving the stability of the inflation valve body and the inflation valve seat.

[0011] Optionally, the inflation valve seat further includes an outer valve seat ring, which is fitted onto the inner valve seat tube. The outer valve seat ring includes a connecting ring, and a limiting space is formed between the connecting ring and the inner valve seat tube. A connecting rod is provided at the outer edge of the connecting ring, and a connecting buckle is provided on the connecting rod. The diameter of the connecting buckle gradually decreases in the direction away from the connecting ring. A connecting hole is provided through the outer ring of the air valve for the connecting rod to pass through.

[0012] By adopting the above technical solution, the connecting buckle is fastened into the connecting hole and the connecting rod passes through the connecting hole. Under the restriction of the connecting buckle, the outer ring of the air valve is not easy to slip off the connecting rod, thereby connecting the air valve body to the air valve seat. At the same time, the air valve body can be flipped while maintaining connection with the air valve seat, which improves the convenience of using the air valve body.

[0013] Optionally, it also includes a valve cover, the outer edge of which is provided with a connecting rib, and the end of the connecting rib away from the valve cover is provided with a connecting ring; the outer ring of the valve seat also includes a mounting ring, and a connecting groove is formed between the mounting ring and the connecting ring, the connecting groove being adapted to the connecting ring.

[0014] By adopting the above technical solution, after the inflatable product has been inflated or deflated, the valve cover can be directly fastened to the outer ring of the valve, thereby improving the airtightness of the inflatable valve body and making it difficult for gas to escape from or enter the inflatable product.

[0015] Optionally, the valve cover has a sealing ridge on its inner edge, and the outer wall of the fixing ring has a sealing groove corresponding to the sealing ridge, the sealing groove being adapted to the sealing ridge.

[0016] By adopting the above technical solution, when the valve cover is fastened to the outer ring of the valve, the sealing ridge is adapted to be embedded in the sealing groove, thereby reducing the gap between the valve cover and the inflation valve body and further improving the airtightness of the inflation valve body.

[0017] Optionally, the inflation valve body further includes an inner valve core, the sealing valve plate is disposed on the inner valve core, the inner valve core is disposed inside the outer valve ring, a plurality of connecting protrusions are provided between the inner valve core and the outer valve ring, the inner valve core and the outer valve ring are connected by the plurality of connecting protrusions, and an avoidance space is formed between the inner valve core and the outer valve ring to avoid the connecting buckle.

[0018] By adopting the above technical solution, the clearance space is set in two ways: firstly, so that the connecting buckle can pass through the connecting hole and be located between the outer ring of the air valve and the inner core of the air valve, so that the air valve body and the air valve seat can be connected; secondly, so that when the air valve body is fixed with the air valve seat, the inner core of the air valve can be adapted to be inserted into the inner tube of the valve seat, thereby improving the inflation and deflation efficiency of the entire air valve.

[0019] Optionally, a positioning plate is provided on the inner wall of the valve core. The positioning plate has a positioning hole and several vent holes. The sealing valve plate is located on one side of the positioning plate. The side of the sealing valve plate facing the positioning plate has a positioning post. The positioning post is adapted to the positioning hole. The positioning post has a positioning buckle.

[0020] By adopting the above technical solution, the positioning buckle is fastened into the positioning hole, and the positioning pin passes through the positioning hole. Under the restriction of the positioning buckle, the sealing valve plate can abut against the positioning plate and block the vent hole. When inflating, the air entering the inflation valve body will push open the sealing valve plate, and then inject the inflatable product. After inflation, the internal air pressure of the inflatable product is greater than the external air pressure, thereby pressing the sealing valve plate against the positioning plate and blocking the vent hole. When deflation, the inflation valve body is flipped to adjust the orientation of the sealing valve plate, and then the inflatable product is squeezed. The air entering the inflation valve body will push open the sealing valve plate, and then expel the inflatable product. After deflation, the external air pressure of the inflatable product is greater than the internal air pressure, and the sealing valve plate is pressed against the positioning plate and blocking the vent hole.

[0021] Optionally, the inflation valve seat further includes a vent pipe, which is located at the end of the valve seat inner tube away from the first fixing groove and is partially located inside the valve seat inner tube. An airtight groove is formed between the vent pipe and the valve seat inner tube. The airtight groove is adapted to the inner core of the air valve and an airtight gasket is provided in the airtight groove.

[0022] By adopting the above technical solution, when the inflation valve body is fixed on the inflation valve seat, the outer edge of the valve core will press against the airtight gasket, thereby enhancing the airtightness between the inflation valve body and the inflation valve seat, making it difficult for gas to escape from between the inflation valve body and the inflation valve seat, and improving the inflation and deflation efficiency.

[0023] Optionally, the vent pipe has several exhaust holes through its side wall, and the end of the vent pipe away from the inner tube of the valve seat has several supporting protrusions spaced apart.

[0024] By adopting the above technical solution, setting an exhaust port makes it easier for gas to be injected into or discharged from the inflatable product, thereby increasing the air flow rate in the inflation valve body and inflation valve seat, and improving the efficiency of inflation and deflation of the inflatable product; when venting the inflatable product, the top support protrusion can open up the fabric of the inflatable product around the inflation valve seat, thereby reducing the possibility of the fabric of the inflatable product adhering to the vent pipe and blocking the vent pipe, so as to ensure that the inflatable product can vent normally as much as possible.

[0025] Optionally, a first mounting groove is formed on the outer wall of the valve seat inner tube, and a second mounting groove is formed on the outer wall of the vent pipe. The valve seat outer ring also includes a first mounting ring and a second mounting ring. The first mounting ring and the second mounting ring are both provided on the inner wall of the valve seat outer ring. The first mounting ring is adapted to be embedded in the first mounting groove, and the second mounting ring abuts against the end of the valve seat inner tube near the vent pipe and is partially embedded in the second mounting groove.

[0026] By adopting the above technical solution, the outer ring of the valve seat can be stably fixed on the inner tube of the valve seat, thereby improving the structural strength of the inflation valve seat and making it less likely for the inner tube of the valve seat to be pushed out of the outer ring of the valve seat when subjected to greater air pressure inside the inflation product.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Insert the fixing protrusion on the fixing ring into the first fixing groove, and rotate the outer ring of the air valve to make the fixing protrusion embed into the second fixing groove. This will fix the inflation valve body on the inflation valve seat. Therefore, the orientation of the sealing valve plate can be adjusted by flipping the inflation valve body. This allows the sealing valve plate to seal the inflation valve seat when the inflation product is being inflated or deflated. As a result, when the inflation product is deflated, external gas is less likely to enter the inflation product, which improves the deflation efficiency and allows the gas inside the inflation product to be discharged more completely.

[0029] 2. When the fixed protrusion is embedded in the second fixed groove, the limiting protrusion is adapted to be embedded in the limiting groove, thereby increasing the friction between the fixed protrusion and the wall of the second fixed groove, making it difficult for the fixed protrusion to slide out of the second fixed groove, thus improving the stability of the inflation valve body and the inflation valve seat.

[0030] 3. Snap the connector into the connector hole and let the connector rod pass through the connector hole. Under the restraint of the connector, the outer ring of the air valve is not easy to slip off the connector rod, thus connecting the air valve body to the air valve seat. At the same time, the air valve body can be flipped while maintaining connection with the air valve seat, which improves the convenience of using the air valve body. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0036] This application discloses a reversible, inflatable cyclone inflation valve. (See also...) Figure 1 and Figure 3 The flip-up cyclone inflation valve includes an inflation valve seat 2. Specifically, the inflation valve seat 2 consists of an inner valve seat tube 21, an air vent tube 23, and an outer valve seat ring 22. In this embodiment, both the inner valve seat tube 21 and the air vent tube 23 are made of acrylonitrile and are integrally molded using a thermoplastic process. The air vent tube 23 is located at the outer edge of one end of the inner valve seat tube 21 and extends partially into the inner valve seat tube 21. An airtight groove 38 is formed between the portion of the air vent tube 23 inside the inner valve seat tube 21 and the inner valve seat tube 21. An airtight gasket 39 is embedded in the airtight groove 38 and is made of rubber. The portion of the air vent tube 23 outside the inner valve seat tube 21 has several vent holes 231 extending through it circumferentially, and the end away from the inner valve seat tube 21 has several support protrusions 40 spaced apart circumferentially.

[0037] Since the portion of the vent pipe 23 located outside the inner tube 21 of the valve seat after the inflation valve seat 2 is fixed to the inflatable product, the vent hole 231 can make it easier for gas to be injected into or discharged from the inflatable product, thereby increasing the air flow rate in the inflation valve seat 2 and improving the efficiency of inflation and deflation of the inflatable product. When deflation of the inflatable product, the top support protrusion 40 can spread the fabric of the inflatable product around the inflation valve seat 2, thereby reducing the possibility of the fabric of the inflatable product adhering to the vent pipe 23 and blocking the vent pipe 23, so as to ensure that the inflatable product can deflate normally as much as possible.

[0038] Reference Figure 1and Figure 2 In this embodiment, the valve seat outer ring 22 is made of polyurethane. During manufacturing, it is formed on the outer wall of the valve seat inner tube 21 using a thermoplastic process and covers the periphery of the valve seat inner tube 21. A first mounting groove 213 is formed on the outer wall of the valve seat inner tube 21 along its own circumference, and a second mounting groove 232 is formed on the outer wall of the vent pipe 23 along its own circumference. A first mounting ring 223 and a second mounting ring 224 are integrally formed on the valve seat outer ring 22 corresponding to the first mounting groove 213 and the second mounting groove 232. The first mounting ring 223 is adapted to be embedded in the first mounting groove 213, and the second mounting ring 224 covers the end of the valve seat inner tube 21 near the vent pipe 23 and is partially embedded in the second mounting groove 232. In fact, both the first mounting ring 223 and the second mounting ring 224 are directly formed in the first mounting groove 213 and the second mounting groove 232 when the outer ring 22 of the valve seat covers the periphery of the inner tube 21 of the valve seat. Therefore, the outer ring 22 of the valve seat can be stably fixed on the inner tube 21 of the valve seat and is not easy to slip off the inner tube 21 of the valve seat.

[0039] Reference Figure 1 and Figure 2 A connecting ring 221 is integrally formed along its circumference on the side of the valve seat outer ring 22 away from the vent pipe 23. A limiting space 7 is formed between the connecting ring 221 and the valve seat inner tube 21. A connecting rod 8 is provided at the outer edge of the connecting ring 221. A connecting buckle 9 is provided at the end of the connecting rod 8 away from the connecting ring 221. The connecting buckle 9 has a frustum-shaped structure, and its diameter gradually decreases in the direction away from the connecting ring 221. In addition, an mounting ring 222 is integrally formed along its circumference on the outer wall of the valve seat outer ring 22. After the valve seat inner tube 21 and the valve seat outer ring 22 have completed the above manufacturing and processing steps, the inflation valve seat 2 is first placed in the pre-reserved hole on the inflatable product. Then, the mounting ring 222 is glued to the fabric of the inflatable product by heat sealing process, so that the inflation valve seat 2 is fixed on the inflatable product. Therefore, while improving the stability of the inflatable valve seat 2 and the inflatable product, the sealing performance between the inflation valve seat 2 and the inflatable product is also improved.

[0040] Reference Figure 1 and Figure 3The flip-type cyclone inflation valve also includes an inflation valve body 1 and a sealing valve plate 3. Specifically, the inflation valve body 1 consists of an outer valve ring 11 and an inner valve core 12. Both sides of the outer valve ring 11 are integrally formed with fixing rings 4. Each pair of fixing rings 4 has several fixing protrusions 5 spaced circumferentially on its inner wall. Limiting grooves 51 are formed on the side of the fixing protrusions 5 facing away from the fixing rings 4. Several first fixing grooves 211 are formed on the outer wall of the valve seat inner tube 21, each corresponding to one of the fixing protrusions 5. Second fixing grooves 212 are formed on one side of each of the first fixing grooves 211, and limiting protrusions 6 are formed on the side wall of each of the second fixing grooves 212 near the vent pipe 23. Furthermore, a connecting hole 111 is provided radially through the side wall of the outer valve ring 11, and the connecting hole 111 is adapted to the connecting rod 8.

[0041] Reference Figure 1 and Figure 2 The valve core 12 is coaxially disposed within the valve outer ring 11, forming a clearance space 34 between them. Several connecting protrusions 33 are spaced circumferentially within the clearance space 34, and the valve core 12 is connected to the valve outer ring 11 via these connecting protrusions 33. A positioning plate 35 is provided within the valve core 12, with a positioning hole 351 and several vent holes 352 extending through it. A positioning post 36 is integrally formed on one side of the sealing valve plate 3 corresponding to the positioning hole 351, and the positioning post 36 is adapted to the positioning hole 351. Furthermore, a positioning buckle 37 is provided on the positioning post 36. Therefore, by passing the positioning post 36 through the positioning hole 351 and embedding the positioning buckle 37 into the positioning hole 351, the sealing valve plate 3 can be fixed to the positioning plate 35, thereby installing the sealing valve plate 3 within the inflation valve body 1. In this embodiment, the positioning buckle 37 is positioned on the positioning post 36 such that after the positioning buckle 37 is embedded in the positioning hole 351, the sealing valve plate 3 can abut against the positioning plate 35 and block the vent hole 352.

[0042] Therefore, during installation, the connecting buckle 9 is placed at the connecting hole 111 and pushed into the connecting hole 111. Since the connecting buckle 9 has a certain elastic deformation capability, it can pass through the connecting hole 111 and be located in the clearance space 34. At this time, the end of the connecting buckle 9 with the larger diameter abuts against the inner wall of the outer ring 11 of the air valve. Under the restriction of the connecting buckle 9, the air valve body 1 can be connected to the air valve seat 2. When inflating the inflatable product, first rotate the inflation valve body 1 so that the side of the sealing valve plate 3 with the positioning post 36 faces downward. Then, rotate the inflation valve body 1 towards the inflation valve seat 2 until the inflation valve body 1 and the inflation valve seat 2 are parallel to each other. Next, push the inflation valve body 1 along the axial direction of the inflation valve seat 2 so that the fixing protrusion 5 is inserted into the first fixing groove 211. At this time, rotate the inflation valve body 1 so that the fixing protrusion 5 is finally embedded in the second fixing groove 212. After the fixing protrusion 5 is embedded in the second fixing groove 212, the limiting protrusion 6 is engaged with the limiting groove 51, thereby increasing the friction between the fixing protrusion 5 and the groove wall of the second fixing groove 212, making it difficult for the fixing protrusion 5 to slide out of the second fixing groove 212, thereby stably fixing the inflation valve body 1 on the inflation valve seat 2.

[0043] After completing the above installation steps, connect the air pump or compressor to the inflation valve body 1 to inflate the inflatable product. When gas enters the inflation valve body 1, it pushes open the sealing valve plate 3 abutting against the positioning plate 35, and then injects gas into the inflatable product through the vent 352. After inflation is complete, because the internal air pressure of the inflatable product is greater than the external air pressure, the sealing valve plate 3, under the action of air pressure, re-abuts against the positioning plate 35 and seals the vent 352, thus sealing the inflation valve body 1 and preventing gas from escaping from the inflatable product. Furthermore, after the inflation valve body 1 is fixed to the inflation valve seat 2, the outer edge of the valve core 12 will press against the airtight gasket 39, thereby improving the airtightness between the inflation valve body 1 and the inflation valve seat 2, making it difficult for gas to escape from between them.

[0044] When venting the inflatable product, first remove the inflation valve body 1 from the inflation valve seat 2, and rotate the inflation valve body 1 so that the side of the sealing valve plate 3 with the positioning post 36 faces upward. Then repeat the above installation steps to fix the inflation valve body 1 to the inflation valve seat 2. At this time, squeezing the inflatable product will vent the product. After the gas enters the inflation valve body 1, it will push open the sealing valve plate 3 which is attached to the positioning plate 35, and then discharge the gas through the vent hole 352. After the venting is completed, since the external air pressure of the inflatable product is greater than the internal air pressure, the sealing valve plate 3 will be pressed against the positioning plate 35 again under the action of air pressure, and block the vent hole 352 to seal the inflation valve body 1, making it difficult for external air to enter the inflatable product, thereby improving the venting efficiency and allowing the gas inside the inflatable product to be discharged more completely.

[0045] Reference Figure 1 and Figure 2 The flip-up cyclone air inflator also includes a valve cover 10. A connecting rib 20 is integrally formed along the edge of the valve cover 10. A connecting ring 30 is integrally formed at the end of the connecting rib 20 away from the valve cover 10. A connecting groove 31 is formed between the mounting ring 222 and the connecting ring 221 on the outer ring 22 of the valve seat, and the connecting groove 31 is adapted to the connecting ring 30. Furthermore, a sealing ridge 32 is integrally formed on the inner edge of the valve cover 10, and a sealing groove 41 is formed along the circumference of the outer wall of the fixing ring 4, and the sealing groove 41 is adapted to the sealing ridge 32. Therefore, by fitting the connecting ring 30 onto the outer ring 22 of the valve seat and embedding it into the connecting groove 31, the air valve cover 10 can be connected to the inflation valve seat 2. After the inflation or deflation of the inflation product is completed, the air valve cover 10 can be flipped over to fasten the air valve cover 10 onto the outer ring 11 of the air valve, and the sealing protrusion 32 can be fitted into the sealing groove 41, thereby further improving the airtightness of the inflation valve body 1, making it difficult for gas to escape from or enter the inflation product.

[0046] The implementation principle of a flip-type cyclone inflation valve in this application embodiment is as follows: When venting the inflation product, rotate the inflation valve body 1 so that the side of the sealing valve plate 3 with the positioning post 36 faces upward, and then flip the inflation valve body 1 towards the inflation valve seat 2 until the inflation valve body 1 and the inflation valve seat 2 are parallel to each other. Then push the inflation valve body 1 along the axial direction of the inflation valve seat 2 so that the fixing protrusion 5 is inserted into the first fixing groove 211. At this time, rotate the inflation valve body 1 so that the fixing protrusion 5 is finally embedded in the second fixing groove 212. After the fixing protrusion 5 is embedded in the second fixing groove 212, the limiting protrusion 6 is engaged in the limiting groove 51, thereby stably fixing the inflation valve body 1 on the inflation valve seat 2. At this time, squeezing the inflatable product will release the gas. After the gas enters the inflation valve body 1, it will push open the sealing valve plate 3 that is abutting against the positioning plate 35, and then discharge through the vent hole 352. After the gas is discharged, since the external air pressure of the inflatable product is greater than the internal air pressure, the sealing valve plate 3 will abut against the positioning plate 35 again under the action of air pressure and block the vent hole 352 to seal the inflation valve body 1, making it difficult for external air to enter the inflatable product, thereby improving the gas discharge efficiency and allowing the gas inside the inflatable product to be discharged more completely.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
