[0002] On the market, most of the objects to be inflated (such as bicycle inner tubes, etc.) are equipped with a Schrader valve or a Presta valve for inflation connection. In response to this, in order to be able to inflate both the objects to be inflated with a Schrader valve and the objects to be inflated with a Presta valve, an inflation device that is universally compatible with both the Schrader valve and the Presta valve has emerged, and the inflation device can be connected to the Schrader valve or the Presta valve through the inflation component thereon.

[0003] Specifically, refer to Fig. 9 The inflatable component includes a shell 100, an inner core component 300 and a limiting component 200. The shell 100 is provided with an air delivery channel S1, the inner core component 300 is arranged in the air delivery channel S1, and the limiting component 200 is detachable to facilitate the user to adjust the inner core component 300 to a first state or a second state, wherein, when the inner core component 300 of the inflatable component is in the first state, the inflatable component can be connected to a Presta valve for inflation; when the inner core component 300 of the inflatable component is in the second state, the inflatable component can be connected to an American valve for inflation.

[0004] However, after many experiments, the inventor found that Fig. 9 When the inner core component 300 of the inflation component is in the first state, there is a first gap between the inner core component 300 and the side wall of the gas delivery channel S1, and a second gap between the inner core component 300 and the limiting component 200. Part of the gas in the gas delivery channel S1 will pass through the first gap and the second gap in turn and then leak out from the first through hole 210 on the limiting component 200, thereby reducing the air tightness of the inflation component when inflating the Presta valve 400, and it is easy to cause the Presta valve 400 to fail to be inflated.

[0043] Reference Figures 1 to 8 An embodiment of the utility model provides an inflatable component, which includes a shell 100, a release-limiting component 200 and an inner core component 300.

[0044] The shell 100 is provided with an air delivery channel S1, and a first opening 130 and a second opening 151 connected to the air delivery channel S1. The limiting member 200 is detachably provided on the shell 100 to close the first opening 130. The limiting member 200 is provided with a first through hole 210 connected to the first opening 130. The inner core component 300 is provided in the air delivery channel S1. The inner core component 300 is in a first state or a second state. The inner core component 300 is provided with a protrusion 311 and a top block 321A.

[0045] It can be understood that the inner core component 300 has a first state and a second state. In other words, the inflatable component has a corresponding first mode and a second mode. The operating steps for converting the inflatable component from the first mode to the second mode are: 1. Disassemble the limiting component 200 to remove the inner core component 300 in the first state from the gas supply channel S1; 2. Adjust the inner core component 300 to the second state and reinstall it into the gas supply channel S1; 3. Install the limiting component 200.

[0046] When the inner core component 300 is in the first state, the protrusion 311 is inserted into the first through hole 210, and the protrusion 311 abuts against the hole wall of the first through hole 210 to seal the gap therebetween. The inner core component 300 is provided with a first channel S2 connected to the air supply channel S1, and the first channel S2 is used for the French gas nozzle to pass through.

[0047] When the inner core component 300 is in the second state, the inner core component 300 is provided with a second channel S3 connected to the gas delivery channel S1, the top block 321A is partially located in the second channel S3, and the first through hole 210 and the second channel S3 are used for the Schrader gas nozzle to pass through in sequence.

[0048] Through the above structure, the protrusion 311 abuts against the hole wall of the first through hole 210 to seal the gap therebetween, so as to limit part of the gas in the gas delivery channel S1 from leaking out from the first through hole 210 on the limiting member 200 after passing through the first gap and the second gap in sequence. Therefore, the airtightness of the Presta valve 400 during the inflation operation can be improved, so as to ensure that the inflation operation of the Presta valve 400 is completed.

[0049] It should be noted that there exists the first gap between the inner core component 300 and the side wall of the gas delivery channel S1 , and there exists the second gap between the inner core component 300 and the stopper 200 .

[0050] When the inner core assembly 300 is in the first state, the protrusion 311 abuts against the hole wall of the first through hole 210. Figure 2 , Figure 3as well as Figure 7 A first inclined surface 311A ​​is formed around the side wall of the protrusion 311 , and a second inclined surface 211 is formed around the hole wall of the first through hole 210 . The first inclined surface 311A ​​abuts against the second inclined surface 211 .

[0051] Through the above structure, the inclined surfaces abut against each other, which can improve the contact tightness between the protrusion 311 and the hole wall of the first through hole 210, so as to further seal the gap between the two, and further improve the air tightness of the Presta valve 400 during inflation.

[0052] In this embodiment, refer to Figure 2 and Figure 5 The shell 100 is provided with a first cavity 110 and a second cavity 120, the first cavity 110 and the second cavity 120 are communicated to form the above-mentioned gas transmission channel S1, the first opening 130 is communicated with the first cavity 110, the second opening 151 is communicated with the second cavity 120, the limiting member 200 is threadedly connected to the shell 100, the inner core component 300 is provided in the first cavity 110, and the limiting member 200 and the cavity bottom of the first cavity 110 jointly clamp the inner core component 300.

The second inner core 320 is a hollow structure, and a partition 321 is provided in the inner cavity of the second inner core 320. The above-mentioned top block 321A is provided on one side of the partition 321 close to one end of the second inner core 320, and the partition 321 is provided with a second through hole 321B.

The inner cavity of the first inner core 310 and the inner cavity of the second inner core 320 are connected to form a first channel S2.

[0056] It is understandable that one end of the second inner core 320 abuts against the bottom of the first cavity 110 , and the top block 321A located on the side of the partition 321 close to one end of the second inner core 320 faces the second cavity 120 without interfering with the inflation work of the Presta valve 400 .

[0057] It can be understood that the partition plate 321 is provided with a second through hole 321B, and the first channel S2 is communicated with the second chamber 120 through the second through hole 321B, that is, the first channel S2 is communicated with the gas delivery channel S1 through the second through hole 321B.

The protrusion 311 is inserted into one end of the second inner core 320, and the top block 321A is passed through one end of the first inner core 310. The inner cavity of the first inner core 310 is the second channel S3.

[0059] It can be understood that the second channel S3 is connected to the inner cavity of the second inner core 320 through the second through hole 321B. The second inner core 320 is a hollow structure. The inner cavity of the second inner core 320 is connected to the second cavity 120. Therefore, it can be seen that the second channel S3 is connected to the second cavity 120 through the second through hole 321B, that is, the second channel S3 is connected to the gas transmission channel S1 through the second through hole 321B.

[0060] It should be noted that, based on the structure of the inner core assembly 300, the specific operating steps for converting the inflatable assembly from the first mode to the second mode are: 1. Disassemble the limiting component 200, and remove the first inner core 310 and the second inner core 320 located in the first cavity 110 through the first opening 130; 2. Flip the first inner core 310 and the second inner core 320, and drive the protrusion 311 to be inserted into one end of the second inner core 320, and the top block 321A is passed through one end of the first inner core 310; 3. Load the flipped and adjusted first inner core 310 and the second inner core 320 into the first cavity 110, and install the limiting component 200, so that the other end of the first inner core 310 abuts against the limiting component 200, and the other end of the second inner core 320 abuts against the bottom of the first cavity 110.

[0061] It should be noted that, based on the structure of the above-mentioned inner core component 300, the specific operating steps for converting the inflatable component from the second mode to the first mode are: 1. Disassemble the limiting component 200, and remove the first inner core 310 and the second inner core 320 located in the first cavity 110 through the first opening 130; 2. Flip the first inner core 310 and the second inner core 320, and drive the other end of the second inner core 320 to be inserted into the other end of the first inner core 310; 3. Load the flipped and adjusted first inner core 310 and second inner core 320 into the first cavity 110, and install the limiting component 200, so that one end of the first inner core 310 abuts against the limiting component 200, the protrusion 311 is inserted into the first through hole 210, and one end of the second inner core 320 abuts against the bottom of the first cavity 110.

[0062] In this embodiment, refer to Figure 3 and Figure 6 The shell 100 is provided with a notch 140 , the notch 140 is located at the edge of the first opening 130 , and the limiting member 200 covers the notch 140 .

[0064] In this embodiment, refer to Figure 2 , Figure 5 as well as Figure 6 At least one sealing ring 312 is provided around the inner cavity wall of the first inner core 310 .

[0065] When the inner core assembly 300 is in the first state, refer to Figure 2 The other end of the second inner core 320 is inserted into the other end of the first inner core 310 , and the sealing ring 312 abuts against the other end of the second inner core 320 to seal the gap therebetween.

[0066] When the inner core assembly 300 is in the second state, refer to Figure 5 The first through hole 210 and the second channel S3 are used for the Schrader valve to pass through in sequence, and the sealing ring 312 is used to abut against the side wall of the Schrader valve to seal the gap therebetween.

[0067] Through the above structure, the design of the sealing ring 312 can, on the one hand, improve the air tightness of the overall first channel S1 when the inner core component 300 is in the first state; on the other hand, it can improve the air tightness of the inflation component when inflating the Schrader valve when the inner core component 300 is in the second state.
