Description

Technical Field

[0001] The invention relates to an air nozzle interface component and an air nozzle compatible air pump integrated machine, belonging to the technical field of air pumps. Background Art

[0002] An air pump is a tool for inflating various inflatable products (such as car tires, motorcycle tires, bicycle tires, balls, inflatable mattresses, inflatable trampolines, inflatable sofas, inflatable toys, etc.). Some existing air pumps have a spiral interface. When in use, a hose is connected to the spiral interface. The other end of the hose has an adapter (such as an American or French gas nozzle adapter), and then the adapter is connected to the gas nozzle of the product to be inflated and inflated.

[0003] However, due to the variety of air nozzles for products to be inflated, for example, the most common air nozzle designs used by mainstream pneumatic tires on the market include American air nozzles and French air nozzles. American air nozzles are short but have a large end diameter, while French air nozzles are long but have a small end diameter. This means that tires equipped with different air nozzles need to be paired with matching inflation adapters when in use, so that they can be inflated through equipment such as air pumps. The existing technology for air pumps to deal with multiple different air nozzles is to use multiple air pipe hoses to deal with different air nozzles respectively, while the air pump interface is a universal interface. The method of using multiple air pipes to deal with different interfaces has the limitation of needing to carry multiple air pipes, and increases the complexity of the operation. It may also be impossible to inflate because of forgetting to bring a certain air pipe hose. Another way is to directly adapt the American valve through the American valve adapter on the air pump air pipe, and then install a separate Presta conversion head on the Presta valve to convert the Presta valve into the interface shape of the American valve, and then inflate. Due to the need for plug-in conversion, the operation is also quite cumbersome, and there is also the risk of forgetting to carry it.

[0004] In addition, a compatible air nozzle adapter has also been proposed. For example, the Chinese invention patent application with application number 2022107999497 discloses an air pump compatible with French and American air nozzles, which specifically discloses an inflation connector and an air pump for an air pump, wherein the inflation connector can adapt to two air nozzles of different specifications, and the air pump integrates the inflation connector, and there is no need to connect a hose, but its structure is quite complicated and the operation is cumbersome. The Chinese utility model patent with application number 2022233172795 discloses a universal air nozzle for a portable air pump and a portable air pump, which adjusts and optimizes the structure of the air nozzle, reduces the volume of the air nozzle, improves the portability of the air pump, and can be adapted to American air nozzles and French air nozzles. However, when it is adapted to a French American nozzle, the American nozzle ejector pin needs to be removed, which is inconvenient to operate and easy to lose. The Chinese utility model patent with application number 2024212241417 also discloses a dual-purpose bicycle air pump nozzle, which can freely switch between French air pump nozzle and American air pump nozzle. However, when switching, it is necessary to remove the middle air core of the nozzle and then invert the sealing sleeve, which is also too cumbersome. Summary of the invention

[0021] The above technical solution of the present invention has the following advantages:

[0022] (1) The present invention sets the air nozzle interface assembly as a telescopic structure, which can be adapted to an American air nozzle for inflation when in a fully contracted state, and can be adapted to a French air nozzle for inflation when in a fully stretched state; the air pump can adapt to two air nozzles of different specifications, and has good adaptability, so that users do not need to carry a variety of hoses or adapters, and do not need to consider storage or forgetting problems, and can realize the free switching of French air nozzles and American air nozzle interfaces, which is extremely convenient and fast. In addition, the present invention only needs to perform stretching or contraction operations to freely switch the type of interface, and the adjustment method is simple and quick when adapting to American air nozzles and French air nozzles respectively, which greatly improves the efficiency of inflation.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Example 1

[0040] This embodiment provides a gas nozzle interface assembly, wherein the gas nozzle interface assembly is configured as a telescopic structure, and when in a fully retracted state, such as Figure 6-8 As shown, it can be connected with a Schrader valve for inflation. When fully stretched, Figure 1-5 As shown, it can be connected to a Presta valve for inflation.

[0041] like Figure 5 As shown, the specific structure of the air nozzle interface assembly includes an air nozzle shaft 1 and a telescopic air nozzle interface 2. The telescopic air nozzle interface 2 is sleeved on the air nozzle shaft 1 (the two are coaxially arranged) and can be telescopic along the air nozzle shaft 1, and can be locked when the telescopic air nozzle interface 2 is in a fully contracted state or a fully stretched (pulled out) state, so that the telescopic air nozzle interface 2 can rotate but cannot move axially, so as to be connected to the air nozzle and then inflated. A first air channel 3 is arranged in the middle of the air nozzle shaft 1, and the telescopic air nozzle interface 2 is arranged with a second air channel 4 for receiving a French air nozzle and a third air channel 5 for receiving an American air nozzle. The first air channel 3, the second air channel 4 and the third air channel 5 are connected in sequence. When inflating, the gas is blown out from the first air channel 3 and then passes through the second air channel 4 and the third air channel 5 in sequence to inflate the air nozzle. The second air channel 4 and the third air channel 5 pass through the telescopic air nozzle interface 2. Since the American gas valve is short but has a large end diameter, while the Presta valve is long but has a small end diameter, a second air channel 4 for accommodating the Presta valve and a third air channel 5 for accommodating the American gas valve are respectively arranged in the telescopic gas valve interface 2. When the gas valve interface assembly is in a fully contracted state, the American gas valve enters the third air channel 5 for inflation, and at this time, the third air channel 5 is combined with the American gas valve; when the gas valve interface assembly is in a fully stretched state, the Presta valve enters through the third air channel 5 and enters the second air channel 4 for inflation, and at this time, the second air channel 4 is combined with the Presta valve to form a certain sealing effect.

[0042] More specifically, when the air nozzle interface assembly is in a fully retracted state, the outer end of the air nozzle shaft 1 extends into the third air channel 5, and when the air nozzle interface assembly is in a fully extended state, the outer end of the air nozzle shaft 1 retracts into the second air channel 4. When inflating, the outer end of the air nozzle shaft 1 pushes open the air nozzle valve of the American or French valve to inflate. The specific structure of pushing open the air nozzle is a mature existing technology and can be directly adopted, and no detailed description is given here. In order to not affect the inflation effect of the present air nozzle interface assembly when the air nozzle shaft 1 pushes open the air nozzle valve of the American or French valve to inflate, a side air outlet 13 can be set at the outer end of the air nozzle shaft 1, and the first air channel 3 and the second air channel 4 are connected through the side air outlet 13, which can ensure a good inflation effect.

[0043] It should be noted that the outer end of the air nozzle shaft 1 mentioned above is relative to the air inlet end of the air nozzle interface assembly or the installation end of the air pump. The air inlet end close to the air nozzle interface assembly is the inner end, and the opposite end is the outer end, and the same applies below.

[0044] More specifically, in the present embodiment, the second air passage 4 and the third air passage 5 are respectively provided with a Presta thread and a Schrader thread matching the Presta valve and the Schrader valve, and when the valve interface assembly is in a fully contracted state and a fully extended state, the telescopic valve interface 2 can be rotated, that is, it can be rotated but without axial movement, so that the Presta thread or Schrader thread inside it can be securely screwed with the thread structure on the Presta valve or the Schrader valve, and then the inflation operation can be performed.

[0045] Example 2

[0046] This embodiment is based on the embodiment 1, and further optimizes and refines the structure of the air nozzle interface assembly. In this embodiment, the air nozzle interface assembly also includes a locking nut 6, and the locking nut 6 is arranged on the air nozzle shaft 1. The locking nut 6 can rotate along the connection between it and the air nozzle shaft 1, and can only rotate without axial movement. The telescopic air nozzle interface 2 is installed in the annular gap between the locking nut 6 and the air nozzle shaft 1. When the air nozzle interface assembly is in a fully contracted state, the telescopic air nozzle interface 2 is locked with the locking nut 6. At this time, the telescopic air nozzle interface 2 can be driven by the locking nut 6 to idle (i.e., rotate without axial movement). When the air nozzle interface assembly is in a fully stretched state, the telescopic air nozzle interface 2 is clamped between the locking nut 6 and the air nozzle shaft 1, and can rotate along the clamping point, and can only rotate without axial movement. Through this structural setting, no matter what kind of air nozzle is inflated, the telescopic air nozzle interface 2 can be kept relatively fixed, which is convenient for stable connection and inflation operations.

[0047] Example 3

[0048] This embodiment is based on the embodiment 2, and provides a specific structural design for how to achieve locking between the telescopic air nozzle interface 2 and the locking nut 6. Specifically, the outer surface of the telescopic air nozzle interface 2 is provided with an external thread, and the inner surface of the locking nut 6 is provided with an internal thread corresponding thereto. When the air nozzle interface assembly is in a fully contracted state, the telescopic air nozzle interface 2 and the locking nut 6 can achieve thread locking. When the air nozzle interface assembly is in a fully extended state, the telescopic air nozzle interface 2 and the locking nut 6 are unthreaded, that is, the telescopic air nozzle interface 2 achieves idling in place. It can be known that the telescopic air nozzle interface 2 can only achieve unthreaded connection with the locking nut 6 if the external thread is provided on part of its outer surface.

[0049] When the air nozzle interface assembly is in the fully stretched state, the specific setting mode of the threaded connection between the telescopic air nozzle interface 2 and the locking nut 6 is as follows: the external thread is set on the outer surface of the telescopic air nozzle interface 2 near the outer end, so after the telescopic air nozzle interface 2 is completely pulled out, the inner end of the telescopic air nozzle interface 2 has no thread, and it cannot continue to be threadedly connected with the locking nut 6, and the telescopic air nozzle interface 2 that has been screwed out of the locking nut 6 cannot directly slide axially into the locking nut 6 due to the obstruction of the thread on its outer surface, and the limiting effect of the air nozzle shaft 1 on it, so that it can only idle in place when it continues to rotate, unless it rotates in the reverse direction, and then returns to the locking nut 6. As for the thread structure inside the locking nut 6, it is most preferred to set only a partial thread on the outer end of the locking nut 6, which is convenient for the screwing of the telescopic air nozzle interface 2 on the one hand, and also convenient for the processing of the locking nut 6 on the other hand.

[0050] In this embodiment, a better choice is to set the telescopic air nozzle interface 2 to be composed of an integrally formed limit portion 7 and a telescopic portion 8, and a limit step is formed at the connection between the limit portion 7 and the telescopic portion 8. When the telescopic air nozzle interface 2 is screwed into the locking nut 6, the telescopic air nozzle interface 2 can be locked by means of the limit step. In this structural setting, the external thread can be set at the outer end of the telescopic portion 8.

[0051] Example 4

[0052] This embodiment is based on Example 3, and optimizes and refines the limiting structure in the air nozzle interface assembly. Specifically, the air nozzle interface assembly described in this embodiment is respectively provided with a first limiting protrusion 9 and a second limiting protrusion 10 on the air nozzle shaft 1, and a first limiting ring 11 and a second limiting ring 12 extending inwardly are respectively provided on the inner ends of the locking nut 6 and the telescopic air nozzle interface 2. The locking nut 6 is limited by the first limiting ring 11 at the first limiting protrusion 9. When in the fully stretched state, the telescopic air nozzle interface 2 is limited by the second limiting ring 12 at the second limiting protrusion 10.

[0053] Example 5

[0054] This embodiment optimizes and refines the sealing structure of the air nozzle interface assembly on the basis of Embodiment 4, specifically:

[0055] The air nozzle interface assembly described in this embodiment is provided with sealing grooves 14 at the inner end of the air nozzle shaft 1, the inner side of the first limiting protrusion 9 and the second limiting protrusion 10, and the junction of the third air channel 5 and the second air channel 4, respectively. An O-type sealing ring is provided in the sealing groove 14 (the sealing groove 14 and the sealing ring on the inner side of the first limiting protrusion 9 and the second limiting protrusion 10 are not shown in the attached drawings). The above-mentioned sealing rings and the Schrader thread and the Presta thread in the telescopic air nozzle interface 2 constitute the sealing system of the air nozzle interface assembly, which can ensure a good sealing effect whether the Schrader air nozzle is inflated in the fully contracted state or the Presta air nozzle is inflated in the fully stretched state.

[0056] Example 6

[0057] This embodiment further optimizes and refines the structure of the air nozzle interface assembly on the basis of Embodiment 5, specifically:

[0058] The air nozzle interface assembly described in this embodiment has a telescopic air nozzle interface 2 and a locking nut 6, each of which is wrapped with a layer of heat-resistant soft rubber (not shown in the drawings), that is, the telescopic air nozzle interface 2 and the locking nut 6 have a double-layer structure, and a layer of heat-resistant soft rubber is wrapped to isolate the high temperature generated by the air nozzle during use.

[0059] Example 7

[0060] This embodiment discloses a nozzle-compatible air pump integrated machine, such as Figure 1-3 As shown, it includes the air nozzle interface assembly in the above embodiment, and also includes an air pump host 15, and the air nozzle interface assembly is installed at the air outlet of the air pump host 15.

[0061] More specifically, the air outlet of the air pump main unit 15 includes a first accommodating chamber 16 and a second accommodating chamber 17, the air nozzle shaft 1 is fixed on the first accommodating chamber 16 and extends out of the air pump main unit 1525~40mm, such as 25mm, 30mm, 35mm and 40mm, preferably 30mm, and the locking nut 6 is installed in the second accommodating chamber 17 and can rotate in the second accommodating chamber 17.

[0062] When using the present invention, if it is necessary to inflate a Schrader gas valve, the telescopic gas valve interface 2 is adjusted to a fully contracted state, and then connected to the Schrader gas valve for inflation. If it is necessary to inflate a French gas valve, the telescopic gas valve interface 2 is adjusted to a fully extended state, and then connected to the French gas valve for inflation.

[0063] In the present invention, the connection between the telescopic air nozzle interface 2, the air nozzle shaft 1, the rotating nut, and the air pump is vertically connected, but it can also be replaced with a hinge connection. In addition, if the locking nut 6 is not provided, it is also possible, for example, the inner surface of the telescopic air nozzle interface 2 and the outer surface of the air nozzle shaft 1 can be respectively provided with threads, and the two can be threadedly connected. However, in this state, the operator needs to have a good judgment on the telescopic distance of the telescopic air nozzle interface 2 relative to the air nozzle shaft 1, so as to be suitable for different air nozzles to inflate.

[0064] In addition, in the present application, the air nozzle shaft 1 and the air pump main unit 15 are fixedly connected, and can also be set to a detachable connection, such as a threaded connection.

[0065] In addition, in the description of the invention, unless otherwise specified, the terms "multiple", "multiple roots", "multiple groups" are used to mean two or more than two, and "several", "several roots", "several groups" are used to mean one or more than one. In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0066] The specific implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
