[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0031] Reference Figures 1 to 9 FIG2 shows an embodiment of an inflation valve according to the present invention. The inflation valve comprises a housing 1, a one-way valve assembly 22, and a first sealing assembly 31 and a second sealing assembly 32. The housing 1 is provided with a first channel 11, a second channel 12, and a third channel 13 connecting the upper airbag and the sole. The second channel 12 and the third channel 13 are respectively connected to the two sides of the first channel 11 and extend upward to the top of the housing 1. The one-way valve assembly 22 is fixed between the two ends of the first channel 11. The first sealing assembly 31 is rotatably connected to the top of the housing 1 for opening or sealing the second channel 12. The second sealing assembly 32 is fixed in the third channel 13 for opening or sealing the third channel 13.

[0032] Specifically, the inflation valve is used to be fixed on the shoe and connect the upper airbag and the sole. When the user steps on the sole, the gas in the sole enters the inflation valve and enters the upper airbag through the inflation valve, thereby making the upper tighter. By adjusting the inflation valve, the flow direction of the gas can be adjusted, thereby adjusting the tightness of the upper.

[0033] The inflation valve includes a shell 1, a one-way valve assembly 22, a first sealing assembly 31, and a second sealing assembly 32. The shell 1 is provided with a first channel 11, a second channel 12, and a third channel 13. The first channel 11 runs through both ends of the shell 1, thereby connecting the sole and the upper airbag, so that gas can flow from the sole to the first channel 11 and to the upper airbag; the second channel 12 and the third channel 13 are both located above the first channel 11, and the second channel 12 and the third channel 13 are respectively located on both sides of the first channel 11, that is, the second channel 12 is arranged near the position of the sole, and the third channel 13 is arranged near the position of the upper airbag, and the second channel 12 and the third channel 13 are both extended upward from one end connected to the first channel 11 and run through to the top of the shell 1, thereby connecting the first channel 11 and the external space at the top of the shell 1; the one-way valve assembly 22 is fixed It is arranged on the first channel 11, and the one-way valve assembly 22 is located between the two ends of the first channel 11, that is, the one-way valve assembly 22 is located between the second channel 12 and the third channel 13. The one-way valve assembly 22 is used to limit the flow direction of the gas so that when the gas is in the first channel 11, it can only flow from the side where the first channel 11 is connected to the sole to the side where the first channel 11 is connected to the upper airbag, and the gas near one end of the upper airbag cannot flow to the sole, thereby improving the structural stability of the inflation valve and ensuring the flow direction of the gas; at the same time, the first sealing assembly 31 is also rotatably arranged on the second channel 12, and the first sealing assembly 31 is rotatably connected to the top of the shell 1. By rotating the first sealing assembly 31, the second channel 12 can be opened or sealed; the second sealing assembly 32 is also fixedly provided inside the third channel 13, and the second sealing assembly 32 is used to open or seal the third channel 13.

[0034] When the second channel 12 and the third channel 13 are both in a sealed state, the gas can only flow through the first channel 11. The gas flows from the sole to the first channel 11 and finally flows to the upper airbag. At this time, the gas goes directly from the sole to the upper, and the tightness of the upper becomes tighter; when the second channel 12 is in an open state and the third channel 13 is in a sealed state, the gas flows from the sole to the first channel 11, flows through the first channel 11 to the second channel 12, and finally is discharged outside the shoe. At this time, the tightness of the upper remains unchanged; when the second channel 12 is in a sealed state and the third channel 13 is in an open state, the gas in the upper airbag flows to the first channel 11 and is discharged to the outside of the shoe through the third channel 13. At this time, the tightness of the upper becomes loose.

[0035] In the present application, the one-way valve assembly 22 is provided in the first channel 11 to control the flow direction of the gas, and the first sealing assembly 31 and the second sealing assembly 32 are adjusted according to actual usage requirements to realize the opening or sealing of the second channel 12 and the third channel 13, thereby changing the flow direction of the gas, thereby realizing the tightness adjustment of the shoe upper. The adjustment method is simple and the sealing performance is high, while improving the tightness effect of the shoe upper and the user experience.

[0036] In a specific embodiment, referring to Figures 1 to 9 As shown, the inflation valve further includes a rotating cover 4, which is rotatably connected to the housing 1 and is provided with a through hole 41 extending through the upper and lower surfaces thereof, the through hole 41 being in communication with the second passage 12 or the third passage 13. Specifically, the inflation valve further includes a rotating cover 4, which is rotatably connected to the housing 1 and is provided with a through hole 41 extending through the upper and lower surfaces thereof, so that a user can rotate the rotating cover 4 to connect the through hole 41 with the second passage 12 or the through hole 41 with the third passage 13.

[0037] When the through hole 41 is connected to the second channel 12, the second channel 12 is in an open state, so that gas can flow from the sole to the first channel 11 and then to the second channel 12, and finally to the through hole 41 until it is discharged outside the shoe; when the through hole 41 is connected to the third channel 13, the third channel 13 is in an open state, so that gas can flow from the upper airbag to the first channel 11, and then to the through hole 41 through the third channel 13, and finally to the outside of the shoe; when the through hole 41 is not connected to the second channel 12 and the third channel 13, the second channel 12 and the third channel 13 are both in a sealed state, and at this time, gas can only flow from the sole to the first channel 11 and then to the upper airbag, thereby tightening the upper. The adjustment method of the inflation valve is simple, and the tightness of the upper can be adjusted by simply rotating the rotating cover 4. The inflation valve has a simple structure and low production cost.

[0038] In one embodiment, referring to Figure 2 、 Figure 5 、 Figure 7 、 Figure 9As shown, the rotating cover 4 is provided with a mounting groove 42 that is recessed upward from its lower surface. The first sealing component 31 is fixedly mounted in the mounting groove 42, and the lower end surface of the first sealing component 31 abuts against the top end of the housing 1. Specifically, the rotating cover 4 is slidably connected to the housing 1. A mounting groove 42 is provided at the lower end of the rotating cover 4. The mounting groove 42 is formed by the upward recess of the lower surface of the rotating cover 4. The mounting groove 42 is used to assemble the first sealing component 31. The size of the mounting groove 42 matches the size of the first sealing component 31. The first sealing component 31 is fixedly mounted in the mounting groove 42, and the lower end surface of the first sealing component 31 abuts against the top end of the housing 1. When the rotating cover 4 is rotated, the first sealing component 31 is driven to rotate so that the first sealing component 31 can open or seal the second channel 12, thereby achieving the opening or closing of the second channel 12 to adjust the flow direction of the gas. This adjustment method is simple, and the structure of fixing the first sealing component 31 to the rotating cover 4 is stable, thereby improving the structural stability of the inflation valve.

[0039] In one embodiment, referring to Figure 3 As shown, the inflation valve further includes a fixing member 7, which is fixedly connected to the rotating cover 4 and is located between the rotating cover 4 and the outer shell 1. The fixing member 7 is provided with a fixing groove that passes through its upper and lower ends, and the fixing groove is fixedly connected to the first sealing component 31. Specifically, the inflation valve further includes a fixing member 7, which is fixedly arranged at the bottom end of the rotating cover 4 and is located between the rotating cover 4 and the outer shell 1. The fixing member 7 is used to fix the first sealing component 31 when the mold is ejected; the fixing member 7 is provided with a fixing groove, the two ends of which pass through the upper and lower ends of the fixing member 7, and the first sealing component 31 is embedded in the fixing groove so that the first sealing component 31 is fixed to the fixing member 7; when the rotating cover 4 rotates, the rotating cover 4 drives the fixing member 7 to rotate, thereby driving the first sealing component 31 to rotate, and then the first sealing component 31 opens or seals the second channel 12. The inflation valve has a simple structure and high sealing performance, and the first sealing component 31 is fixed by the fixing member 7, thereby improving the structural stability of the inflation valve and facilitating demoulding during the production of the inflation valve, thereby improving production efficiency.

[0040] In a specific embodiment, referring to Figure 7As shown, the first sealing component 31 includes a sealing silicone 311 , and an opening 3111 is provided on one side of the sealing silicone 311 . The opening 3111 is used to connect the second channel 12 and the through hole 41 . Specifically, the first sealing component 31 is fixed in the mounting groove 42, and the first sealing component 31 includes a sealing silicone 311. The sealing silicone 311 is fixed in the mounting groove 42, and an opening 3111 is provided on one side of the sealing silicone 311. The opening 3111 passes through the upper and lower ends of the sealing silicone 311, and the opening 3111 is arranged corresponding to the through hole 41. When the rotating cover 4 rotates, it drives the sealing silicone 311 to rotate until the opening 3111 slides to a position opposite to the second channel 12. At this time, the opening 3111 connects the second channel 12 and the through hole 41, so that the second channel 12 is in an open state, and the gas can flow from the sole to the first channel 11 and be discharged outside the shoe through the second channel 12, the opening 3111 and the through hole 41; when the rotating cover 4 drives the sealing silicone 311 to rotate so that the opening 3111 is not connected to the second channel 12, the second channel 12 is in a sealed state. The first sealing assembly 31 in this embodiment has a simple structure and a simple adjustment method, good sealing performance, and improved adjustment effect.

[0041] In one embodiment, referring to Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 9As shown, the second sealing component 32 includes a stainless steel ball 321, which is fixed in the third channel 13, and the upper end surface of the stainless steel ball 321 abuts against the lower surface of the rotating cover 4. Specifically, the second sealing component 32 includes a stainless steel ball 321, which is fixed in the third channel 13, and the upper end surface of the stainless steel ball 321 abuts against the lower surface of the rotating cover 4, thereby utilizing the close contact between the stainless steel ball 321 and the lower surface of the rotating cover 4 to achieve a sealing effect. Under normal working conditions, the stainless steel ball 321 will be pressed against the lower surface of the rotating cover 4 to form a very tight sealing line. This sealing line is like an indestructible barrier that can effectively prevent gas leakage. At the same time, when the gas pressure increases, the contact pressure between the stainless steel ball 321 and the lower surface of the rotating cover 4 will also increase accordingly, further enhancing the sealing effect. This sealing method is not only reliable, but also resistant to high pressure and wear, and has high reliability. When the rotating cover 4 is rotated until the through hole 41 is connected to the third channel 13, the stainless steel ball 321 does not form a sealing barrier with the lower surface of the rotating cover 4, so that the gas can flow from the upper airbag to the first channel 11 and enter the third channel 13, flow to the through hole 41 until it is discharged outside the shoe.

[0042] The second sealing assembly 32 in this embodiment has high structural stability and good sealing performance, thereby improving the effect of adjusting the tightness of the shoe upper.

[0043] In one embodiment, referring to Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 9 As shown, the second sealing assembly 32 also includes a sealing ring 322, which is sleeved on the outside of the stainless steel ball 321 and fixedly connected to the third channel 13. Specifically, the second sealing assembly 32 also includes a sealing ring 322, which is sleeved on the outside of the stainless steel ball 321, that is, the sealing ring 322 surrounds the stainless steel ball 321 inside, and the sealing ring 322 is fixed in the third channel 13, that is, the sealing ring 322 is located between the groove wall of the third channel 13 and the stainless steel ball 321. At the same time, the bottom of the sealing ring 322 avoids the stainless steel ball 321, so that gas can flow from the first channel 11 to the third channel 13 and then flow through the stainless steel ball 321 to the through hole 41 to the outside of the shoe. The sealing ring 322 further improves the sealing performance of the stainless steel ball 321, preventing gas leakage, and at the same time, the sealing ring 322 can also improve the stability of the fixation between the stainless steel ball 321 and the third channel 13.

[0044] In one embodiment, referring to Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 9 As shown, the rotating cover 4 is provided with a through hole 43 passing through its upper and lower ends, and the inflation valve further includes a gear indicator 5. One end of the gear indicator 5 passes through the through hole 43 and is fixedly connected to the housing 1, and the gear indicator 5 is rotatably connected to the rotating cover 4. Specifically, the middle portion of the rotating cover 4 is further provided with a through hole 43 passing through its upper and lower ends, and the inflation valve further includes a gear indicator 5. The gear indicator 5 is used to display the gear position. The top end of the gear indicator 5 is clamped above the through hole 43, and the bottom end of the gear indicator 5 passes through the through hole 43 to be fixedly connected to the housing 1, and the gear indicator 5 is rotatably connected to the rotating cover 4. The upper end of the gear indicator 5 is marked with gear information. When the rotating cover 4 is rotated, the rotating cover 4 rotates, and the gear indicator 5 remains stationary, so that the gear information can be used to determine whether the rotating cover 4 is rotated into place, thereby improving the user's ease of operation.

[0045] In this embodiment, the gear indicator 5 is marked with three gear information of "OUT", "CUT" and "△". When the rotating cover 4 is rotated to the "△" gear, the first sealing component 31 and the second sealing component 32 both seal the second channel 12 and the third channel 13, so that the second channel 12 and the third channel 13 are both in a sealed state, and the gas can only flow from the sole to the first channel 11 and then to the upper airbag, thereby tightening the upper; when the rotating cover 4 is rotated to the "OUT" gear, the first sealing component 31 Open the second channel 12, and the second sealing component 32 seals the third channel 13. At this time, the gas flows from the sole to the first channel 11, flows to the second channel 12 through the first channel 11, and is finally discharged outside the shoe. At this time, the tightness of the shoe upper remains unchanged; when the rotating cover 4 is rotated to the "CUT" position, the first sealing component 31 seals the second channel 12, and the second sealing component opens the third channel 13. At this time, the gas in the upper airbag flows to the first channel 11 and is discharged to the outside of the shoe through the third channel 13. At this time, the tightness of the shoe upper becomes loose.

[0046] In a specific embodiment, referring to Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 9As shown, the one-way valve assembly 22 includes a one-way valve 21 and a mounting block 22. The mounting block 22 is sleeved on the outside of the one-way valve 21, and the mounting block 22 is embedded in the shell 1. The one-way valve 21 is located in the first channel 11 to connect the two sides of the first channel 11. Specifically, the one-way valve assembly 22 is used to limit the flow direction of the gas to ensure that the gas can only flow from the sole to the upper airbag. The one-way valve assembly 22 includes a one-way valve 21 and a mounting block 22. The mounting block 22 is used to fix the one-way valve 21, and the mounting block 22 is sleeved on the outside of the one-way valve 21. The mounting block 22 is fixedly connected to the one-way valve 21, and the mounting block 22 is embedded in the shell 1. The mounting block 22 is located within the range of the first channel 11. The one-way valve assembly 22 divides the first channel 11 into two areas. The side of the first channel 11 close to the sole is connected to the second channel 12, and the side of the first channel 11 close to the upper airbag is connected to the third channel 13. The one-way valve 21 is fixed in the first channel 11, so that the one-way valve 21 is connected to both sides of the first channel 11, so that the gas only flows from the sole to the side of the first channel 11 close to the sole and flows to the side of the first channel 11 close to the upper airbag through the one-way valve 21, thereby ensuring the flow direction of the gas, thereby improving the structural stability of the inflation valve and the effect of adjusting the tightness of the upper.

[0047] More specifically, the one-way valve 21 is a duckbill valve.

[0048] In one embodiment, referring to Figures 1 to 9 As shown, the inflation valve further includes a mounting base 6, one side of which is fixedly connected to the bottom end of the housing 1, and the other side is fixedly connected to the upper. Specifically, the inflation valve further includes a mounting base 6, which is used to fix the inflation valve to the upper. One side of the mounting base 6 is fixedly connected to the housing 1, and the other end is fixedly connected to the upper. The mounting base 6 is sewn to the upper by sewing, thereby achieving the fixation of the inflation valve and the upper. The inflation valve has a simple structure and high installation efficiency.
