Furthermore, because the connection between the inflatable airbag and the air delivery device can be achieved through the magnetic force between the first magnetic member in the male connector and the second magnetic member in the female connector, the connection between the inflatable airbag and the air delivery device can be established and disconnected relatively easily compared to a connection achieved via a threaded knob.

DETAILED DESCRIPTION

[0037] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and should not be understood as limiting the embodiments of the present application.

[0038] In related technologies, high-pressure pipes, gas nozzles, valves, and other components are typically connected using threaded knobs to ensure a tight and sealed connection. However, in scenarios where plugging and unplugging are frequent, components connected using threaded knobs are cumbersome to install and remove. Furthermore, turning the knobs without proper alignment or turning them frequently over a long period of time can damage the seal of the connection interface.

[0039] Based on the above problems, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The present application provides a connector 1000, comprising a male connector 1100 including a first body 1110 and a first magnetic member 1120. The first body 1110 defines a first air channel 1111 and a receiving cavity 1112, the first air channel 1111 communicating with the receiving cavity 1112, and the first magnetic member 1120 is disposed in the receiving cavity 1112 and surrounds an air channel opening 1113 of the first air channel 1111. A female connector 1200 includes a second body 1210 and a second magnetic member 1220. The second body 1210 defines a second air channel 1211 and a receiving cavity 1212, the second air channel 1211 communicating with the receiving cavity 1212, and the second magnetic member 1220 surrounds an air channel opening 1213 of the second air channel 1211. When the male connector 1100 is inserted into the receiving cavity 1212 , the first magnetic member 1120 is magnetically connected to the second magnetic member 1220 so that the first air passage 1111 is connected to the second air passage 1211 .

[0040] Thus, in the embodiment of the present application, the inflatable airbag can be connected to an air delivery device such as an air pump based on the connector 1000, thereby receiving gas delivered by the air delivery device through the first air channel 1111 and the second air channel 1211 to achieve inflation. At the same time, because the connection between the inflatable airbag and the air delivery device can be achieved based on the magnetic force between the first magnetic member 1120 in the male connector 1100 and the second magnetic member 1220 in the female connector 1200, the connection between the inflatable airbag and the air delivery device can be relatively simple to establish and disconnect compared to the case of connection via a threaded knob, thereby meeting the user's needs for frequent plugging and unplugging, and avoiding the situation in which the interface seal is damaged due to inaccurate alignment and long-term frequent knob rotation in the threaded knob method.

[0041] In one example, one of the first magnetic member 1120 and the second magnetic member 1220 is a raw magnet, or a magnetic object made of a magnetic material such as iron, nickel, or cobalt, and the other is an object that can be magnetically attracted. Thus, when the male connector 1100 including the first magnetic member 1120 is brought into proximity with the female connector 1200 including the second magnetic member 1220, the male connector 1100 and the female connector 1200 can fit together, thereby connecting the first airway 1111 with the second airway 1211.

[0042] In one example, the first magnetic member 1120 is a raw magnet, or a magnetic object composed of a magnetic material such as iron, nickel, and cobalt. The second magnetic member 1220 is a raw magnet with opposite magnetic properties to the first magnetic member 1120, or a magnetic object composed of a magnetic material such as iron, nickel, and cobalt. Thus, when the male connector 1100 including the first magnetic member 1120 is close to the female connector 1200 including the second magnetic member 1220, the male connector 1100 can fit with the female connector 1200, thereby connecting the first airway 1111 with the second airway 1211.

[0043] In one example, the first magnetic member 1120 and the second magnetic member 1220 each include a plurality of magnetic members, thereby ensuring that the magnetic force between the first magnetic member 1120 and the second magnetic member 1220 is sufficient.

[0044] In one example, the first magnetic member 1120 and the second magnetic member both include neodymium iron boron magnets (NdFeB Magnet).

[0045] In one example, the receiving cavity 1212 is a circular surface with a side wall, and the side wall can wrap the male connector 1100 to ensure a stable connection between the male connector and the female connector.

[0046] Please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the first body 1110 includes:

[0047] A first upper cover plate 1114 is provided with a first through hole 1115 , and a first lower cover plate 1116 is connected to the first upper cover plate 1114 to form an accommodating cavity 1112 .

[0048] The first lower cover plate 1116 defines a second through hole 1117 . The second through hole 1117 is disposed opposite to the first through hole 1115 and communicates with the airway opening 1113 of the first airway 1111 .

[0049] Thus, in the embodiment of the present application, the first body 1110 of the male connector 1100 can be realized by the first upper cover plate 1114 and the first lower cover plate 1116 .

[0050] In one example, the first upper cover plate 1114 and the first lower cover plate 1116 are both made of metal. Therefore, after the first magnetic member 1120 is placed in the receiving cavity 1112 formed by the first upper cover plate 1114 and the first lower cover plate 1116, the first body 1110 of the male connector 1100 is magnetic, thereby interacting with the second magnetic member 1220 in the second body 1210.

[0051] In one example, the first upper cover plate 1114 and the first lower cover plate 1116 are both made of plastic.

[0052] In one example, the first upper cover plate 1114 and the first lower cover plate 1116 are both plastic products made based on a mold.

[0053] In one example, the first upper cover plate 1114 and the first lower cover plate 1116 are fixedly connected to each other to form a closed space for placing the first magnetic member 1120 , that is, the aforementioned accommodating cavity 1112 .

[0054] Please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the first lower cover plate 1116 is formed with a first groove 1118 , the first groove 1118 is arranged around the first through hole 1115 , and the first magnetic member 1120 is arranged in the first groove 1118 .

[0055] Specifically, in order to ensure the stability of the first magnetic member 1120 relative to the first body 1110, in certain embodiments of the present application, a first groove 1118 surrounding the first through hole 1115 is opened in the first lower cover plate 1116, and then the first magnetic member 1120 can be placed in the first groove 1118.

[0056] In this way, in certain embodiments of the present application, the first magnetic member 1120 can be placed in the first groove 1118 .

[0057] In one example, the first groove 1118 is in the shape of a ring. Accordingly, the first magnetic member 1120 is a ring-shaped magnetic object, or a ring-shaped object that can be adsorbed on a magnetic object.

[0058] In one example, the first groove 1118 is a trapezoidal groove, and correspondingly, the first magnetic member 1120 is a trapezoidal magnetic object, or a ring-shaped object that can be adsorbed on a magnetic object.

[0059] Please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the first body 1110 includes a first connecting portion 1119, and the first connecting portion 1119 is used for the air pump.

[0060] Specifically, in order to achieve the connection between the air pump and the male connector 1100, in an embodiment of the present application, the first body 1110 of the male connector 1100 is also provided with a first connecting portion 1119, so that the air pump can be connected to the first body 1110 of the male connector 1100 through the first connecting portion 1119.

[0061] In one example, the first connecting portion 1119 is a hollow cylinder with a threaded inner surface.

[0062] In one example, the first connecting portion 1119 is a hollow cylinder with threads on the outer surface.

[0063] In one example, the first connection portion 1119 is a snap-fit ​​structure. In other words, the air pump can be connected to the first connection portion 1119 by a snap-fit ​​connection.

[0064] In one example, the first connecting portion 1119 is a sleeve structure, in other words, the first connecting portion 1119 can be connected with the gas conveying pipe of the air pump based on a nested form.

[0065] Thus, in the embodiments of the present application, the air pump can be connected with the male head 1100 through the first connecting portion 1119 of the male head 1100.

[0066] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments of the present application, the second body 1210 further comprises:

[0067] The second upper cover plate 1214 is provided with a third through hole 1215. The second lower cover plate 1216 is connected with the second upper cover plate 1214 to form a sealed space 1221. The second lower cover plate 1216 is provided with a fourth through hole 1217 which is oppositely arranged with the third through hole 1215 and communicates with the air passage port 1213 of the second air passage 1211. An end surface of the second lower cover plate 1216 which is away from the second upper cover plate 1214 forms a receiving cavity 1212.

[0068] Thus, in the embodiments of the present application, the second body 1210 of the female head 1200 can be realized based on the second upper cover plate 1214 and the second lower cover plate 1216.

[0069] Specifically, in the embodiments of the present application, the second body 1210 of the female head 1200 comprises two parts, one of which is the second upper cover plate 1214 and the other of which is the second lower cover plate 1216.

[0070] Further, the second upper cover plate 1214 is provided with the third through hole 1215, and the second lower cover plate 1216 is provided with the fourth through hole 1217 which is positionally matched with the third through hole 1215, or in other words, in the case of fixed connection between the second upper cover plate 1214 and the second lower cover plate 1216, the fourth through hole 1217 is directly opposite to the third through hole 1215, so that the fourth through hole 1217, the third through hole 1215 and the air passage port 1213 of the second air passage 1211 are communicated with each other, so that the air bag can be inflated by the gas transmitted along the second air passage 1211, the third through hole 1215 and the fourth through hole 1217.

[0071] In one example, when the second lower cover plate 1216 is connected with the second upper cover plate 1214, the inner side of the second lower cover plate 1216 and the inner side of the second upper cover plate 1214 jointly form a sealed space 1221, and the second magnetic member 1220 can be placed in the sealed space, thereby ensuring the stable placement of the second magnetic member 1220 in the female head 1200.

[0072] In one example, the second lower cover plate 1216 and the second upper cover plate 1214 are both made of metal. Therefore, after the second magnetic member 1220 is placed between the second lower cover plate 1216 and the second upper cover plate 1214 to form a sealed space 1221, the second body 1210 of the female connector 1200 is magnetic, thereby interacting with the first magnetic member 1120 in the first body 1110.

[0073] In one example, the second lower cover plate 1216 and the second upper cover plate 1214 are both made of plastic.

[0074] In one example, the first upper cover plate 1114 and the first lower cover plate 1116 are both plastic products made based on a mold.

[0075] Please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the second lower cover plate 1216 is formed with a second groove 1218 , the second groove 1218 is arranged around the fourth through hole 1217 , and the second magnetic member 1220 is arranged in the second groove 1218 .

[0076] Thus, in the embodiment of the present application, the second magnetic member 1220 can be disposed in the second groove 1218 of the second lower cover plate 1216 to ensure that the second magnetic member 1220 is stably placed in the female connector 1200 .

[0077] Specifically, in order to ensure the stable placement of the second magnetic part 1220 in the female head 1200, in certain embodiments of the present application, a second groove 1218 for placing the second magnetic part 1220 is provided in the second lower cover plate 1216, so that the second magnetic part 1220 is placed in the second groove 1218 and thus fixed inside the female head 1200.

[0078] In one example, the second groove 1218 is annular in shape, and accordingly, the second magnetic member 1220 is an annular magnetic object, or an annular object that can be adsorbed on a magnetic object.

[0079] In one example, the second groove 1218 is a trapezoidal groove, and correspondingly, the second magnetic member 1220 is a trapezoidal magnetic object, or a ring-shaped object that can be adsorbed on a magnetic object.

[0080] Please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the second body 1210 includes a second connecting portion 1219, and the second connecting portion 1219 is used to inflate the airbag.

[0081] Specifically, to achieve the robust connection of the female head 1200 to the inflator, in the embodiments of the present application, the second body 1210 is further provided with a second connecting portion 1219, and further, the inflator can be connected to the second connecting portion 1219, so as to achieve the connection to the female head 1200.

[0082] In one example, the second connecting portion 1219 is a hollow cylinder with threads on the inner surface.

[0083] In one example, the second connecting portion 1219 is a hollow cylinder with threads on the outer surface.

[0084] In one example, the second connecting portion 1219 is a snap-on structure, in other words, the inflator can be connected to the second connecting portion 1219 by snap-on connection.

[0085] In one example, the second connecting portion 1219 is a sleeve structure, in other words, the second connecting portion 1219 and the gas delivery pipe of the air pump can be connected in a nested form.

[0086] In this way, in the embodiments of the present application, the inflator can be connected to the female head 1200 through the second connecting portion 1219 of the second body 1210.

[0087] Corresponding to the above-mentioned connector 1000, the embodiments of the present application also provide an inflating system, which comprises an air pump, an inflator and the above-mentioned connector 1000, and the air pump and the inflator are connected through the connector 1000.

[0088] In one example, the first body 1110 of the male head 1100 comprises a first connecting portion 1119 for the air pump, and the second body 1210 of the female head 1200 comprises a second connecting portion 1219 for the inflator. In this way, the gas delivery pipe of the air pump is connected to the first connecting portion 1119 of the first body of the male head 1100, the male head 1100 and the female head 1200 are connected through the magnetic force action between the first magnetic member 1120 and the second magnetic member 1220, and the second connecting portion 1219 of the second body of the female head 1200 and the gas inlet pipe of the inflator are connected to each other, and further, the gas generated by the air pump can enter the inflator along the gas delivery pipe of the air pump, the first gas passage 1111 of the male head 1100, the second gas passage 1211 of the female head 1200 and the gas inlet pipe of the inflator, so as to achieve the inflation of the inflator by the air pump.

[0089] At the same time, when the user wants to give up inflating the inflatable airbag, he can drag the air pump outlet pipe connected to the male head 1100 to disconnect the connection between the male head 1100 and the female head 1200 based on the magnetic force between the first magnetic part 1120 and the second magnetic part 1220, and then disconnect the connection between the air pump and the inflatable airbag.

[0090] Correspondingly, if the user wants to resume inflation of the inflatable airbag, the air pump outlet pipe connected to the male head 1100 is dragged to bring the male head 1100 close to the female head 1200. Then, a connection relationship is established between the male head 1100 and the female head 1200 based on the magnetic force between the first magnetic part 1120 and the second magnetic part 1220, so that the air pump outlet pipe, the first air channel 1111 of the male head 1100, the second air channel 1211 of the female head 1200 and the air inlet pipe of the inflatable airbag are connected in sequence, and the connection relationship between the air pump and the inflatable airbag is restored.

[0091] Thus, in the embodiment of the present application, the inflatable airbag can be connected to an air delivery device such as an air pump based on the connector 1000, thereby receiving gas delivered by the air delivery device through the first air channel 1111 and the second air channel 1211 to achieve inflation. At the same time, because the connection between the inflatable airbag and the air delivery device can be achieved based on the magnetic force between the first magnetic member 1120 in the male connector 1100 and the second magnetic member 1220 in the female connector 1200, the connection between the inflatable airbag and the air delivery device can be relatively simple to establish and disconnect compared to the case of connection via a threaded knob, thereby meeting the user's needs for frequent plugging and unplugging, and avoiding the situation in which the interface seal is damaged due to inaccurate alignment and long-term frequent knob rotation in the threaded knob method.
