[0042] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0043] Please refer to Figures 1-8 The specific embodiments provided by the present application are as follows:

[0044] Reference Figure 1 And Figure 2 As shown in the figure, the universal air nozzle is designed to provide a portable device that can be connected to different types of air nozzles (such as American air nozzle 1 and French air nozzle 2). Specifically, through this portable universal air nozzle, the user can connect the American air nozzle 1 or the French air nozzle 2 to the inflating equipment (such as an inflating pump) to achieve universal adaptation of different air nozzles.

[0045] The universal air nozzle is mainly composed of an air nozzle body 3, which includes a first connection port 301 and a second connection port 302. Among them, the first connection port 301 is used for sealing connection with the American air nozzle 1 or the French air nozzle 2, and the second connection port 302 is used for connection with the inflating equipment. In addition, according to the needs, the first connection port 301 is connected with the inflating equipment, and the second connection port 302 is connected with the American air nozzle 1 or the French air nozzle 2.

[0046] In this embodiment, the first connection mode is adopted, in which the air nozzle body 3 is composed of a first shell 303 and a second shell 306, and the two are detachably connected. Specifically, one end of the first shell 303 is provided with a port, which can be clamped with the port of the second shell 306 to form a columnar air nozzle body 3.

[0047] The end face of the first shell 303 is provided with an opening, i.e. the first connection port 301, which is used for sealing connection with the American air nozzle 1 or the French air nozzle 2. The end face of the second shell 306 is also provided with an opening, i.e. the second connection port 302, which is used for connection with the inflating equipment. Usually, the end face of the second shell 306 also has a protruding connection nozzle 304, which forms a through channel inside and is connected with the second connection port 302. Through the connection nozzle 304, the gas outlet of the inflating equipment can be sealingly connected, so that the gas is pumped out from the inflating equipment, passes through the channel of the connection nozzle 304, enters the inside of the air nozzle body 3, and then flows into the American air nozzle 1 or the French air nozzle 2 through the first connection port 301.

[0048] Among them, the first shell 303 and the second shell 306 are in a connected state, and a certain installation space is formed inside to install the thimble 4.

[0049] Referring to Figure 7 and Figure 8 As shown, the needle 4 is arranged inside the air nozzle body 3, i.e. inside the installation space. The needle 4 comprises a needle head 401 and a needle body 402.

[0050] The needle body 402 is a hollow tube with one end open and the other end sealed, i.e. having a sealed end 4021. From the open end of the needle body 402 to the sealed end 4021, an air nozzle channel 4022 is formed for the air nozzle, especially the French air nozzle 2, to be inserted into. When the nozzle body of the French air nozzle 2 is inserted into the air nozzle channel 4022, the valve core of the French air nozzle 2 is abutted against the inner side wall surface of the sealed end 4021, so that the valve core of the French air nozzle 2 is pried open.

[0051] Referring to Figure 7 and Figure 8 As shown, the sealed end 4021 of the needle body 402 has a first air port 501. The first air port 501 is directed towards the second connecting port 302, and the airflow passes through the second connecting port 302, the first air port 501, enters the inside of the needle body 402, and flows into the French air nozzle 2.

[0052] In an embodiment, the first air port 501 can be circular or rectangular. It forms a circular array at the sealed end 4021. For example, the first air port 501 can be 2, 4, 6, etc.

[0053] In some embodiments, as shown, the circumferential wall surface of the needle body 402 has a second air port 502. Part of the valve core of the French air nozzle 2 has a larger diameter, which blocks the airflow passage between the first air port 501 and the nozzle body of the French air nozzle 2, causing the airflow to decrease. Based on this, the second air port 502 is added. The second air port 502 allows the airflow entering from the first air port 501 to flow out from the second air port 502, into the gap between the second air port 502 and the inside of the air nozzle body 3, increasing the storage space of the airflow, and avoiding the decrease of the airflow to cause the decrease of the inflation efficiency.

[0054] In an embodiment, the second air port 502 is a waist-shaped hole. It is arranged equidistantly on the circumferential wall surface of the needle body 402. For example, the second air port 502 can be 2, 4, etc.

[0055] Referring to Figure 7 and Figure 8 As shown, the needle head 401 is a column, which is installed on the outer side wall surface of the sealed end 4021. The diameter of the needle head 401 is smaller than the diameter of the needle body 402, and is also smaller than the diameters of the second connecting port 302 and the first connecting port 301.

[0056] The needle head 401 has two installation states:

[0057] Referring toFigure 3 and Figure 4 As shown in FIG. 1 and FIG. 2, in one installation state, the gas nozzle body 3 is adapted to the American gas nozzle 1. Specifically, the needle 401 is directed towards the first connecting port 301. The American gas nozzle 1 is installed to the first connecting port 301, the valve core is in contact with the needle 401 of the thimble 4, and the needle 401 pushes the valve core for a distance to open the valve core of the American gas nozzle 1.

[0058] Referring to Figure 5 and Figure 6 As shown in FIG. 3 and FIG. 4, in another installation state, the gas nozzle body 3 is adapted to the French gas nozzle 2. Specifically, the needle 401 is directed towards the second connecting port 302. The French gas nozzle 2 is installed to the first connecting port 301, and the valve core extends to the gas nozzle channel 4022 of the thimble 4, and abuts against the inner side wall surface of the sealing end 4021, and the valve core of the French gas nozzle 2 is opened.

[0059] The gas nozzle body 3 is internally provided with a sealing ring 6, which is installed at a position close to the first connecting port 301. The sealing ring 6 forms a connecting channel 601, which is suitable for the connection of the American gas nozzle 1 and the French gas nozzle 2, such as threaded connection or tight clamping. Specifically, the nozzle body of the American gas nozzle 1 or the French gas nozzle 2 is in tight contact with the inner wall of the connecting channel 601, which ensures the formation of a seal during the connection process to prevent gas leakage. Through this design, whether it is the American gas nozzle 1 or the French gas nozzle 2, a reliable airtight connection can be achieved.

[0060] The sealing ring 6 is made of silica gel or rubber.

[0061] In one specific embodiment, the sealing ring 6 has a sealing groove 602. The sealing groove 602 is directed towards the thimble 4. In either of the aforementioned installation states, the sealing groove 602 can form a sealing connection with the sealing end 4021 or the circumferential wall surface of the needle body 402 to ensure airtightness.
