Description

Technical Field

[0001] This utility model relates to the field of inflatable devices, and in particular to an inflatable connecting component and an inflatable device. Background Technology

[0002] Most inflatable objects on the market (such as bicycle tires) have valves for inflation. Different objects use different valves (the valves can be British, French, or American). Some manufacturers have designed and produced interchangeable connectors to fit British, French, or American valves. These connectors can be connected to an air pump to inflate objects with the corresponding valves. However, market research and user feedback revealed the following problems with these connectors: 1. Replacing the connectors is cumbersome, making them unfriendly to novice users; 2. Replaced connectors are easily lost. Therefore, the inventors of this application aim to solve the technical problem of developing a connector that eliminates the need for connector replacement and is compatible with British, French, and American valves. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a connecting assembly for inflation.

[0004] This utility model also proposes an inflation device having the inflation connection component.

[0005] An inflatable connecting assembly according to a first aspect of the present invention includes a shell assembly and a movable core. The shell assembly has a first cavity, a second cavity, a third cavity, a fourth cavity, a first hole, and a second hole. The first cavity, the third cavity, and the fourth cavity each have an opening communicating with the outside. The first cavity and the third cavity are respectively connected to the second cavity through the first hole and the second hole. The second cavity is connected to the fourth cavity. The movable core is movably disposed in the second cavity. The movable core has a first abutment portion and a second abutment portion. The first abutment portion passes through the first hole into the first cavity, and the second abutment portion passes through the second hole into the third cavity. A British-style air valve is inserted into the first cavity through a corresponding opening, and when the first abutment portion pushes the movable core to move to the point of blocking the second hole, it exits from the fourth cavity. Gas entering through the opening can sequentially pass through the fourth chamber, the second chamber, and the first hole before breaching the valve body of the British valve to enter the British valve. A French valve, with the locking nut loosened, is inserted into the first chamber through its corresponding opening. When the first abutment pushes the movable core to block the second hole, the first abutment opens the valve core of the French valve, allowing gas entering from the opening of the fourth chamber to sequentially pass through the fourth chamber, the second chamber, and the first hole before entering the French valve. An American valve, with its corresponding opening, is inserted into the third chamber. When the second abutment pushes the movable core to block the first hole, the second abutment opens the valve core of the American valve, allowing gas entering from the opening of the fourth chamber to sequentially pass through the fourth chamber, the second chamber, and the second hole before entering the American valve.

[0006] An inflatable connecting assembly according to an embodiment of the present invention has at least the following beneficial effects:

[0007] The process of a user inflating an object with a British valve using an inflation device equipped with the connecting components of this application is as follows: 1. The British valve is driven to be inserted into the first cavity through the corresponding opening, and the British valve is moved to the second hole by pushing the movable core through the first abutment part; 2. The inflation device is driven to input gas from the opening of the fourth cavity, so that the gas passes through the fourth cavity, the second cavity and the first hole in sequence and then blows open the valve skin of the British valve to enter the British valve and inflate the object.

[0008] The process of a user inflating an object with a French valve using an inflation device equipped with the connection component of this application is as follows: 1. Loosen the locking nut of the French valve; 2. Drive the French valve to be inserted into the first cavity through the corresponding opening, so that the French valve moves to the second hole by pushing the movable core through the first abutment part, and the first abutment part opens the valve core of the French valve; 3. Drive the inflation device to input gas from the opening of the fourth cavity, so that the gas passes through the fourth cavity, the second cavity and the first hole in sequence and enters the French valve to inflate the object.

[0009] The process of a user inflating an object with an American-style valve using an inflation device equipped with the connection component of this application is as follows: 1. The American-style valve is driven to be inserted into the third chamber through the corresponding opening, so that the American-style valve moves to the first hole by pushing the movable core through the second abutment part, and the second abutment part opens the valve core of the American-style valve; 2. The inflation device is driven to input gas from the opening of the fourth chamber, so that the gas passes through the fourth chamber, the second chamber and the second hole in sequence and enters the American-style valve to inflate the object.

[0010] With the above structure, the connecting components of this application do not require replacement of accessories. When the user inserts the valve (one of the British valve, French valve, and American valve) on the object to be inflated into the corresponding first or third chamber, inflation can be started. Thus, the process of switching to inflating an object with another type of valve does not require the user to replace the connecting accessories, which is very user-friendly for novice users. Moreover, it can avoid the situation where the connecting accessories are lost due to replacement.

For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] Reference Figures 1 to 4 This utility model provides an inflatable connecting component, which includes a shell component 100 and a movable core 200.

[0040] The shell assembly 100 is provided with a first cavity 121, a second cavity S, a third cavity 131, a fourth cavity 112, a first hole 122, and a second hole 132. The first cavity 121, the third cavity 131, and the fourth cavity 112 all have openings that communicate with the outside. The first cavity 121 and the third cavity 131 are respectively connected to the second cavity S through the first hole 122 and the second hole 132. The second cavity S is connected to the fourth cavity 112. The movable core 200 is movably disposed in the second cavity S. The movable core 200 is provided with a first abutment part 210 and a second abutment part 220. The first abutment part 210 passes through the first hole 122 into the first cavity 121, and the second abutment part 220 passes through the second hole 132 into the third cavity 131.

[0041] The process of a user inflating an object with a British valve using an inflation device equipped with the connection components of this application is as follows: 1. The British valve is driven to be inserted into the first cavity 121 through the corresponding opening, so that the British valve is moved to the second hole 132 by pushing the movable core 200 through the first abutment part 210; 2. The inflation device is driven to input gas from the opening of the fourth cavity 112, so that the gas passes through the fourth cavity 112, the second cavity 112 and the first hole 122 in sequence and then blows open the valve skin of the British valve to enter the British valve and inflate the object to be inflated.

[0042] The process of a user inflating an object with a French valve using an inflation device equipped with the connection components of this application is as follows: 1. Loosen the locking nut of the French valve; 2. Drive the French valve to be inserted into the first cavity 121 through the corresponding opening, so that the French valve moves to the second hole 132 by pushing the movable core 200 through the first abutment part 210, and so that the first abutment part 210 opens the valve core of the French valve; 3. Drive the inflation device to input gas from the opening of the fourth cavity 112, so that the gas passes through the fourth cavity 112, the second cavity 112 and the first hole 122 in sequence and enters the French valve to inflate the object.

[0043] The process of a user inflating an object with an American-style valve using an inflation device equipped with the connection components of this application is as follows: 1. The American-style valve is driven to be inserted into the third chamber 131 through the corresponding opening, so that the American-style valve pushes the movable core 200 through the second abutment part 220 to move to the blocking first hole 122, and the second abutment part 220 opens the valve core of the American-style valve; 2. The inflation device is driven to input gas from the opening of the fourth chamber 112, so that the gas passes through the fourth chamber 112, the second chamber S and the second hole 132 in sequence and enters the American-style valve to inflate the object.

[0044] It is understandable that when the movable core 200 moves to block the second hole 132, the connection between the second cavity S and the third cavity 131 is cut off, and the gas in the second cavity S cannot enter the third cavity 131; when the movable core 200 moves to block the first hole 122, the connection between the second cavity S and the first cavity 121 is cut off, and the gas in the second cavity S cannot enter the first cavity 121.

[0045] With the above structure, the connecting components of this application do not require replacement of accessories. When the user inserts the valve (one of the British valve, French valve, and American valve) on the object to be inflated into the corresponding first chamber 121 or third chamber 131, inflation can be performed. Thus, the process of switching to inflating an object with another type of valve does not require the user to replace the connecting accessories, which is very user-friendly for novice users. Moreover, it can avoid the situation where the connecting accessories are lost due to replacement.

[0046] The movable core 200 is moved to seal the second hole 132. For details, please refer to [link / reference]. Figure 2 The second abutment part 220 is fitted with a first sealing ring 610, and the first sealing ring 610 and the second abutment part 220 move to jointly seal the second hole 132.

[0047] The movable core 200 is moved to seal the first hole 122. For details, please refer to... Figure 2 The first abutment part 210 is fitted with a second sealing ring 620, and the second sealing ring 620 and the first abutment part 210 move to jointly seal the first hole 122.

[0048] In this embodiment, refer to Figures 1 to 3The openings of the first cavity 121 and the third cavity 131 are opposite each other and located on the same straight line. The system also includes a hollow adapter pipe 300. One end of the adapter pipe 300 is rotatably inserted into the fourth cavity 112 through a corresponding opening. The cavity wall of the fourth cavity 112 abuts against one end of the adapter pipe 300 to seal the gap between them. The straight line along which the openings of the first cavity 121 and the third cavity 131 are located is perpendicular to the rotation axis of the adapter pipe 300. The other end of the adapter pipe 300 is used to connect to an inflation module (such as an air pump or inflator) via a pipe fitting, so that the inflation module and the overall connecting assembly can be assembled into an inflation device. The inflation module can input gas into the other end of the adapter pipe 300.

[0049] With the above structure, on the one hand, the adapter 300 allows the inflation device to input gas from the other end of the adapter 300 instead of the opening of the fourth chamber 112 during the inflation process when the user uses an inflation device equipped with the connection component of this application to inflate an object with a British, French, or American valve. On the other hand, the adapter 300 is rotatably mounted on the housing assembly 100, and its angle can be adjusted to adapt to the position of the valve, catering to the user's inflation habits. It can also reduce the torque on the pipe, extend the service life of the pipe and even the inflation device, optimize ergonomics, and improve the user's operating comfort.

[0050] The wall of the fourth cavity 112 abuts against one end of the transfer pipe fitting 300 to seal the gap between them. Specifically, refer to... Figure 2 One end of the adapter pipe 300 is fitted with a fifth sealing ring 650, and one end of the adapter pipe 300 abuts against the cavity wall of the fourth cavity 112 through the fifth sealing ring 650.

[0051] In this embodiment, specifically, refer to Figure 2 The fourth cavity 112 has a first groove 112A on its cavity side wall, and the outer side wall of one end of the adapter pipe 300 has a second groove 310. The second groove 310 and the first groove 112A are arranged inside and outside each other. A sixth sealing ring 660 is sleeved on one end of the adapter pipe 300. A part of the sixth sealing ring 660 is located in the first groove 112A and the other part is located in the second groove 310.

[0052] With the above structure, part of the sixth sealing ring 660 is located in the first groove 112A and the other part is located in the second groove 310, so as to reduce the probability that the transfer pipe 300 will detach from the fourth cavity 112 through the corresponding opening.

[0053] The housing assembly 100 includes a base housing 110, a first air nozzle connector 120, and a second air nozzle connector 130.

[0054] Reference Figure 2 and Figure 3 The base shell 110 is provided with a through hole 111 and a fourth cavity 112. A first air nozzle connector 120 is inserted through one of the openings of the through hole 111. The wall of the through hole 111 abuts against the first air nozzle connector 120 to seal the gap between them. The first air nozzle connector 120 is provided with the first cavity 121, the first hole 122 and the first cavity segment 123 connected in sequence. A second air nozzle connector 130 is inserted through the other opening of the through hole 111. The wall of the through hole 111 abuts against the second air nozzle connector 130 to seal the gap between them. The second air nozzle connector 130 is provided with the third cavity 131, the second hole 132 and the second cavity segment 133 connected in sequence. The portion of the second air nozzle connector 130 located in the through hole 111 is fitted with a portion of the second cavity segment 133 onto the portion of the first air nozzle connector 120 located in the through hole 111, so that the first cavity segment 123 and the remaining second cavity segments 133 are connected to form the second cavity S.

[0055] The wall of the through hole 111 abuts against the first air nozzle connector 120 to seal the gap between them. Specifically, refer to... Figure 2 The first air nozzle connector 120 is fitted with a third sealing ring 630, and the first air nozzle connector 120 abuts against the wall of the through hole 111 through the third sealing ring 630.

[0056] The wall of the through hole 111 abuts against the second air nozzle connector 130 to seal the gap between them. Specifically, refer to... Figure 2 The second air nozzle connector 130 is fitted with a fourth sealing ring 640, and the second air nozzle connector 130 abuts against the wall of the through hole 111 through the fourth sealing ring 640.

[0057] The second cavity S is connected to the fourth cavity 112. For details, please refer to... Figure 2 The base shell 110 is provided with a fifth hole 113 that connects the through hole 111 and the fourth cavity 112. The second air nozzle connector 130 is provided with a sixth hole 135 that connects the through hole 111 and the second cavity S. The sixth hole 135 and the fifth hole 113 are both located between the third sealing ring 630 and the fourth sealing ring 640. The second cavity S, the sixth hole 135, the through hole 111, the fifth hole 113 and the fourth cavity 112 are connected in sequence.

[0058] In some embodiments, the portion of the first air nozzle connector 120 located in the through hole 111 is fitted with a portion of the second air nozzle connector 130 located in the through hole 111 through a portion of the first cavity segment 123, so that the second cavity segment 133 and the remaining first cavity segment 123 are connected to form the aforementioned second cavity S.

[0059] In this embodiment, refer to Figure 2 and Figure 3The first air nozzle connector 120 and the second air nozzle connector 130 are both detachably inserted into the through hole 111. The second air nozzle connector 130 is threaded onto the portion of the first air nozzle connector 120 located in the through hole 111 through a portion of the second cavity section 133, so that the first air nozzle connector 120 and the second air nozzle connector 130 are detachably connected.

[0060] With the above structure, the first air nozzle connector 120 and the second air nozzle connector 130 are detachably installed to facilitate production assembly and subsequent maintenance and repair work.

[0061] In some embodiments, the first air nozzle connector 120 and the second air nozzle connector 130 are both detachably inserted through the through hole 111. The first air nozzle connector 120 is threaded onto the portion of the second air nozzle connector 130 located in the through hole 111 through a portion of the first cavity 123, so that the first air nozzle connector 120 and the second air nozzle connector 130 are detachably connected.

[0062] In this embodiment, refer to Figure 2 and Figure 3 The first air nozzle connector 120 and the second air nozzle connector 130 are respectively provided with a third abutment portion 124 and a fourth abutment portion 134. When the first air nozzle connector 120 is rotated relative to the second air nozzle connector 130, or when the second air nozzle connector 130 is rotated relative to the first air nozzle connector 120, the third abutment portion 124 and the fourth abutment portion 134 can move towards each other so as to jointly clamp the base shell 110.

[0063] In this embodiment, refer to Figure 2 and Figure 3 The first air nozzle connector 120 is provided with a mounting groove 125. The opening of the first cavity 121 is located on the bottom wall of the mounting groove 125. The mounting groove 125 is provided with a sealing core 400. The side wall of the mounting groove 125 abuts against the sealing core 400 to seal the gap between them. The sealing core 400 is provided with a third hole 410. When a British or French air nozzle is inserted into the first cavity 121 through the third hole 410 and the corresponding opening, the wall of the third hole 410 abuts against the corresponding British or French air nozzle to seal the gap between them.

[0064] With the above structure, the wall of the third hole 410 is used to abut against the corresponding British or French valve to seal the gap between them, so as to improve air tightness and avoid the situation where air leakage occurs and the British or French valve cannot be inflated.

[0065] To prevent the sealing core 400 from detaching from the mounting groove 125, refer to... Figure 2 and Figure 3The first air nozzle connector 120 is fitted with a release element 500. The sealing core 400 is located inside the release element 500 and is pressed against the bottom wall of the mounting groove 125 by the release element 500. The release element 500 is provided with a fourth hole 510. A British-style air nozzle or a French-style air nozzle can be inserted into the first cavity 121 in sequence through the fourth hole 510, the third hole 410, and the corresponding opening.

[0066] In this embodiment, refer to Figure 2 and Figure 3 The sealing core 400 has an annular protrusion 420, which is inserted into the fourth hole 510. The wall of the fourth hole 510 abuts against the protrusion 420 to seal the gap between them. A British or French air nozzle can be inserted into the first cavity 121 sequentially through the inner hole of the protrusion 420, the third hole 410, and the corresponding opening.

[0067] It is understandable that when the British or French valve passes through the inner hole of the protrusion 420, that is, when the British or French valve passes through the fourth hole 510.

[0068] In this embodiment, refer to Figure 2 and Figure 3 The third cavity 131 is provided with a seventh sealing ring 670. When the American-style air nozzle is inserted into the third cavity 131 through the corresponding opening, the seventh sealing ring 670 can be fitted onto the American-style air nozzle and seal the gap between the American-style air nozzle and the cavity wall of the third cavity 131, thereby improving the airtightness when the American-style air nozzle is being inflated.

[0069] In this embodiment, refer to Figure 4 The base shell 110 is provided with a first marking portion 114 corresponding to the second air nozzle connector 130, and a second marking portion 115 corresponding to the first air nozzle connector 120. The user can identify the first marking portion 114 to insert an American-style air nozzle into the third cavity 131 of the second air nozzle connector 130, and can identify the second marking portion 115 to insert a British-style or French-style air nozzle into the first cavity 121 of the first air nozzle connector 120. Therefore, the inclusion of the first marking portion 114 and the second marking portion 115 can significantly reduce the occurrence of misaligned air nozzle installation by the user, thereby improving the accuracy of air nozzle installation and optimizing the user experience.

[0070] This invention also proposes an inflation device, which includes the aforementioned inflation connection assembly. With this structure, the process of inflating an object with a different type of nozzle can be switched without requiring the user to change the connection parts, making it very user-friendly for novice users.

[0071] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
