[0052] The utility model will be further described below in conjunction with the accompanying drawings.

[0053] See also Figure 1In the first aspect, the embodiment of the present application discloses a pipeline buffer mechanism 1, comprising a first joint 11, a guide tube 13 and a buffer 14. The first joint 11 has an air inlet end 1111 and an air outlet end 1112 opposite to each other, and the air inlet end 1111 is used to connect to the air source. One end of the guide tube 13 is connected to the air outlet end 1112, and the other end is used to be inserted into the port of the pipeline 4 and can move in the pipeline 4. The buffer 14 is sleeved on the guide tube 13, and the two ends of the buffer 14 can respectively abut the end surface of the air outlet end 1112 and the end surface of the port of the pipeline 4.

[0054] In this embodiment and the following embodiments, the pipeline 4 may be the pipeline 4 of two components (ie, the condenser and the evaporator) in the air conditioner, or may be other pipelines 4, which are not limited here.

[0055] Among them, the gas source is used to transport protective gases such as nitrogen.

[0056] The air inlet end 1111 and the air outlet end 1112 of the first connector 11 can be selectively connected or disconnected. For example, when the air inlet end 1111 is not connected to the gas source, the air inlet end 1111 and the air outlet end 1112 are disconnected, which can prevent the nitrogen and other protective gases that have been input into the pipeline 4 from overflowing through the air inlet end 1111, and prevent the air from the external environment from entering the pipeline 4 from the air inlet end 1111, so as to ensure the purity of the nitrogen and other protective gases in the pipeline 4, thereby avoiding oxidation of the pipeline 4 with the air during welding; when the air inlet end 1111 is connected to the gas source, the air inlet end 1111 and the air outlet end 1112 are connected, so that the nitrogen and other protective gases can flow from the air inlet end 1111 to the air outlet end 1112 and finally flow into the pipeline 4. Of course, the air inlet end 1111 and the air outlet end 1112 of the first connector 11 can also be continuously connected.

[0057] In this embodiment, when the first connector 11 is connected to the gas source, the first connector 11 may be subjected to an impact force, which causes the first connector 11 to approach the pipeline 4, and the impact force is transmitted from the first connector 11 to the guide tube 13. The guide tube 13 can move in the pipeline 4 under the action of the impact force, thereby preventing the guide tube 13 from continuing to transmit the impact force to the pipeline 4, thereby avoiding damage to the pipeline 4.

[0058] In this embodiment, the two ends of the buffer 14 can respectively abut against the air outlet end 1112 of the first joint 11 and the end face of the pipe 4 port, thereby playing a buffering role in the process of the first joint 11 approaching the pipe 4 port, and preventing the pipe 4 port from being damaged due to contact with the first joint 11. Of course, the buffer 14 can also be connected to the air outlet end 1112 at only one end, and a gap is formed between the other end and the end face of the pipe 4 port. When the first joint 11 moves a certain distance toward the end of the pipe 4, the buffer 14 abuts against the end face of the pipe 4 port and plays a buffering role. In addition, the buffer 14 can also be connected only to the end face of the pipe 4 port, and the other end forms a gap with the first joint 11, which will not be elaborated here.

[0059] The working principle of this embodiment is that the guide tube 13 can be first connected and communicated with the air outlet end 1112 of the first joint 11, and the buffer member 14 is sleeved on the guide tube 13, and then the end of the guide tube 13 away from the first joint 11 is inserted through the port 4 of the pipeline.

[0060] Then move the first connector 11 toward the gas source and connect it to the gas source. During the connection process, the first connector 11 may be subjected to impact force. However, due to the relative movement of the guide tube 13 and the pipeline 4, the impact force will not be transmitted to the pipeline 4. At the same time, the buffer component 14 plays a buffering role between the first connector 11 and the port of the pipeline 4, thereby avoiding damage to the pipeline 4.

[0061] Finally, the gas source outputs a protective gas such as nitrogen, which passes through the gas inlet end 1111 of the first connector 11 , the gas outlet end 1112 of the first connector 11 and the guide pipe 13 in sequence, and finally flows into the pipeline 4 .

[0062] See also Figure 2 In some embodiments, the first connector 11 includes a first housing 111 and a first ejector pin 112. The first housing 111 has an air inlet 1111, an air outlet 1112, and a first vent 1113, and the first vent 1113 connects the air inlet 1111 with the air outlet 1112. The first ejector pin 112 is movably disposed in the first vent 1113 to connect or disconnect the first vent 1113 with the air inlet 1111.

[0063] In this embodiment, when the air inlet end 1111 is not connected to the air source, the first ejector pin 112 is in a position capable of closing the first air vent 1113, and at this time, the first air vent 1113 is connected to the air outlet end 1112 and disconnected from the air inlet end 1111; when the air inlet end 1111 is connected to the air source, the first ejector pin 112 moves to a position that connects the first air vent 1113 to the air inlet end 1111, thereby connecting the air inlet end 1111, the first air vent 1113 and the air outlet end 1112.

[0064] Exemplarily, when the air inlet end 1111 is not connected to the air source, the first ejector pin 112 may be located between the first air vent 1113 and the air inlet end 1111, so that the first air vent 1113 is disconnected from the air inlet end 1111; when the air inlet end 1111 is connected to the air source, the first ejector pin 112 is away from the air inlet end 1111 and close to the air outlet end 1112, so that the air inlet end 1111, the first air vent 1113 and the air outlet end 1112 are connected.

[0065] By setting the first ejector pin 112, the first vent hole 1113 can be disconnected from the air inlet end 1111 when the air inlet end 1111 is not connected to the air source, thereby preventing the protective gas such as nitrogen that has been input into the pipeline 4 from overflowing through the air inlet end 1111. At the same time, it can prevent the air from the external environment from flowing from the air inlet end 1111 into the pipeline 4, thereby ensuring the concentration of protective gas such as nitrogen in the pipeline 4.

[0066] In some other embodiments, the first connector 11 may also only include the first shell 111 , so that the air inlet 1111 , the first air hole 1113 and the air outlet 1112 are continuously connected.

[0067] Please continue reading Figure 2 In some more specific embodiments, the first connector 11 further includes a first elastic member 113 , which is disposed in the first vent hole 1113 and applies a first elastic force to the first ejector pin 112 for disconnecting the first vent hole 1113 from the air inlet end 1111 .

[0068] In this embodiment, when the air inlet end 1111 is not connected to the air source, the first elastic force applied by the first elastic member 113 to the first ejector pin 112 causes the first ejector pin 112 to be in a position that disconnects the first air hole 1113 and the air inlet end 1111; when the air inlet end 1111 is connected to the air source, the first elastic force is overcome to move the first ejector pin to a position where the first air hole 1113 and the air inlet end are connected.

[0069] Exemplarily, when the air inlet end 1111 is not connected to the air source, the first ejector pin 112 can be located between the first air vent 1113 and the air inlet end 1111 under the action of the first elastic force, so that the first air vent 1113 is disconnected from the air inlet end 1111; when the air inlet end 1111 is connected to the air source, the first elastic force is overcome, so that the first ejector pin 112 is away from the air inlet end 1111 and close to the air outlet end 1112, thereby connecting the air inlet end 1111, the first air vent 1113 and the air outlet end 1112.

[0070] By providing the first elastic member 113, it can be ensured that the first ejector pin 112 disconnects the first air hole 1113 from the air inlet end 1111 when the air inlet end 1111 is not connected to the air source. At the same time, when the air inlet end 1111 is connected to the air source, only the first elastic force needs to be overcome to connect the first air hole 1113 with the air inlet end 1111, thereby reducing the complexity of the structure.

[0071] In some other more specific embodiments, the first ejector pin 112 may also be driven by a driving member such as a motor.

[0072] See also Figure 3 In some more specific embodiments, the pipeline buffer mechanism 1 also includes a second connector 12 for communicating with the gas source, and the second connector 12 can be plugged into the gas inlet end 1111.

[0073] In this embodiment, the second connector 12 and the first connector 11 can both be quick connectors, that is, when the second connector 12 is inserted into the air inlet end 1111 of the first connector 11, the second connector 12 can be stably connected to the first connector 11, so that the second connector 12 and the first connector 11 can be quickly connected and the operation is simple, thereby improving the docking efficiency. In addition, the guide tube 13 is connected and communicated with the air outlet end 1112. In addition, the second connector 12 is communicated with a gas source for conveying a protective gas such as nitrogen.

[0074] The air inlet end 1111 and the air outlet end 1112 of the first connector 11 can be selectively connected or disconnected. For example, when the air inlet end 1111 of the first connector 11 is separated from the second connector 12, the air inlet end 1111 and the air outlet end 1112 are disconnected, which can prevent the nitrogen and other protective gases that have been input into the pipeline 4 from overflowing through the air inlet end 1111, and at the same time prevent the air from the external environment from entering the pipeline 4 through the air inlet end 1111, so as to ensure the purity of the nitrogen and other protective gases in the pipeline 4, thereby avoiding oxidation of the pipeline 4 with the air during welding; when the air inlet end 1111 of the first connector 11 is plugged into the second connector 12, the air inlet end 1111 and the air outlet end 1112 are connected, so that the nitrogen and other protective gases can flow from the second connector 12 through the air inlet end 1111 to the air outlet end 1112, and finally flow into the pipeline 4. Of course, the air inlet end 1111 and the air outlet end 1112 of the first connector 11 may also be continuously connected, which is not limited here.

[0075] Similarly, the two ends of the second connector 12 can also be selectively connected or disconnected. For example, when the second connector 12 is separated from the gas inlet end 1111 of the first connector 11, the two ends of the second connector 12 are disconnected, thereby preventing the nitrogen or other protective gas output from the gas source from overflowing through the second connector 12, causing waste of nitrogen or other protective gas. Of course, the two ends of the second connector 12 can also be continuously connected, which is not limited here.

[0076] When the second connector 12 is plugged into the air inlet end 1111 of the first connector 11 , the second connector 12 may be completely inserted into the first connector 11 , or may be partially inserted into the first connector 11 , which is not limited herein.

[0077] In this embodiment, when the second connector 12 is plugged into the first connector 11, the second connector 12 will apply an impact force toward the pipeline 4 to the first connector 11. The impact force causes the first connector 11 to approach the pipeline 4, and the impact force is transmitted from the first connector 11 to the guide tube 13. The guide tube 13 can move in the pipeline 4 under the action of the impact force, thereby preventing the guide tube 13 from continuing to transmit the impact force to the pipeline 4, thereby preventing the pipeline 4 from being damaged by the impact force.

[0078] The working principle of this embodiment is that the guide tube 13 can be first connected and communicated with the air outlet end 1112 of the first joint 11, and the buffer member 14 is sleeved on the guide tube 13, and then the end of the guide tube 13 away from the first joint 11 is installed on the pipeline 4.

[0079] Then align the second connector 12 with the air inlet end 1111 of the first connector 11, and bring the second connector 12 and the first connector 11 closer to each other, so that the second connector 12 is plugged into the air inlet end 1111, so that the air outlet end 1112 of the first connector 11 is connected to the second connector 12. During the plugging process, the impact force exerted by the second connector 12 on the first connector 11 will not be transmitted to the pipeline 4 due to the relative movement of the guide tube 13 and the pipeline 4, and the buffering effect of the buffer 14 between the first connector 11 and the port of the pipeline 4 is combined to avoid damage to the pipeline 4.

[0080] Finally, the gas source outputs nitrogen or other protective gas, which passes through the second connector 12 , the gas inlet end 1111 of the first connector 11 , the gas outlet end 1112 of the first connector 11 and the guide pipe 13 in sequence, and finally flows into the pipeline 4 .

[0081] In some other embodiments, the first connector 11 may be directly connected to the gas source.

[0082] See also Figure 4 In some embodiments, the second connector 12 includes a second housing 121 and a second ejector pin 122. The second housing 121 has a second through hole 1211 for connecting to an air source, and the second housing 121 can be plugged with the air inlet end 1111 so that the second air hole 1211 can be connected to the air inlet end 1111. The second ejector pin 122 is movably disposed at the second air hole 1211 to open or close the second air hole 1211.

[0083] In this embodiment, when the second joint 12 is separated from the air inlet end 1111 of the first joint 11, the second ejector pin 122 is in a position capable of closing the second vent hole 1211, thereby closing the second vent hole 1211, so that the second vent hole 1211 is disconnected from the air inlet end 1111. It should be noted that at this time, the second vent hole 1211 can be connected to the gas source and disconnected from the external environment, thereby preventing nitrogen and other protective gases from overflowing through the second joint 12, thereby reducing the loss rate of nitrogen and other protective gases.

[0084] When the second connector 12 is plugged into the air inlet end 1111 of the first connector 11 , the second ejector pin 122 switches to a position capable of opening the second air hole 1211 , thereby opening the second air hole 1211 so that the second air hole 1211 can communicate with the air inlet end 1111 .

[0085] It is understandable that when the second ejector pin 122 switches from the position of closing the second vent hole 1211 to the position of opening the second vent hole 1211, it can be driven by the first connector 11, and of course it can also be driven by other driving components, which is not limited here.

[0086] In some other embodiments, the second joint 12 may also only include the second shell 121 , so that the second vent hole 1211 is continuously in an open state.

[0087] Please continue reading Figure 4 In some more specific embodiments, the second joint 12 further includes a second elastic member 123 , which is disposed at the second vent hole 1211 and applies a second elastic force to the second ejector pin 122 for closing the second vent hole 1211 .

[0088] In this embodiment, when the second connector 12 is separated from the air inlet end 1111 of the first connector 11 , the second elastic force applied by the second elastic member 123 to the second ejector pin 122 causes the second ejector pin 122 to be in a position to close the second vent hole 1211 , thereby closing the second vent hole 1211 .

[0089] When the second connector 12 is plugged into the air inlet end 1111 of the first connector 11 , the second elastic force is overcome to switch the second ejector pin 122 to a position capable of opening the second air hole 1211 , thereby opening the second air hole 1211 so that the second air hole 1211 is connected to the air inlet end 1111 .

[0090] By providing the second elastic member 123, it can be ensured that the second ejector pin 122 closes the second air hole 1211 when the second connector 12 is separated from the first connector 11. At the same time, when the second connector 12 is plugged into the air inlet end 1111 of the first connector 11, the second air hole 1211 can be opened by overcoming the second elastic force, so that the second air hole 1211 is connected to the air inlet end 1111, thereby reducing the complexity of the structure for opening or closing the second air hole 1211.

[0091] In some other more specific embodiments, the second ejector pin 122 may also be driven by a driving member such as a motor.

[0092] See also Figure 4 In some embodiments, when the second shell 121 is plugged into the air inlet end 1111 , the second ejector pin 122 and the first ejector pin 112 abut against and push each other to open the second vent hole 1211 and connect the first vent hole 1113 to the air inlet end 1111 .

[0093] In this embodiment, when the second shell 121 is plugged into the air inlet end 1111 of the first joint 11, the second ejector pin 122 contacts the first ejector pin 112, and the second ejector pin 122 pushes the first ejector pin 112 to connect the first air vent 1113 with the air inlet end 1111. At the same time, the first ejector pin 112 pushes the second ejector pin 122 to open the second air vent 1211, thereby connecting the second air vent 1211, the air inlet end 1111, the first air vent 1113 and the air outlet end 1112, and the structure is simple.

[0094] In some other more specific embodiments, the second connector 12 and the first connector 11 may be driven by a driving member such as a motor.

[0095] Please refer again Figure 2 In some more specific embodiments, the inner wall of the first connector 11 is provided with a receiving groove 114, and the outer wall of the second connector 12 is provided with a clamping groove 124. The first connector 11 further includes a locking member 115, which is movably provided in the receiving groove 114 and can partially protrude from the receiving groove 114. When the second connector 12 is plugged into the air inlet end 1111 and the clamping groove 124 is opposite to the receiving groove 114, the portion of the locking member 115 protruding from the receiving groove 114 is clamped in the clamping groove 124.

[0096] The locking member 115 may be in a spherical shape or in other shapes such as a cuboid, which is not limited here.

[0097] In this embodiment, when the second connector 12 is separated from the air inlet end 1111 of the first connector 11, the locking member 115 can protrude from the receiving groove 114 or can be accommodated in the receiving groove 114, which is not limited here. It can be understood that the locking member 115 protrudes from the receiving groove 114 or is accommodated in the receiving groove 114 means that the side of the locking member 115 facing away from the outer wall of the first connector 11 (that is, the outer wall of the first shell 111) can protrude from the inner wall of the first connector 11 (that is, the inner wall of the first shell 111) or can be accommodated in the receiving groove 114.

[0098] During the process of inserting the second connector 12 into the air inlet end 1111 of the first connector 11, the locking piece 115 can be accommodated in the receiving groove 114 to avoid interference between the locking piece 115 and the first connector 11, until the positions of the slot 124 on the outer wall of the second connector 12 and the receiving groove 114 on the inner wall of the first connector 11 are relative to each other, and the locking piece 115 protrudes out of the receiving groove 114 and engages with the slot 124, that is, the side of the locking piece 115 facing away from the outer wall of the first connector 11 protrudes out of the inner wall of the first connector 11 and engages with the slot 124, thereby realizing the plug-in connection between the second connector 12 and the first connector 11.

[0099] When the pipeline 4 of the two-device assembly is filled with a protective gas such as nitrogen or welding is completed, the side of the locking member 115 away from the outer wall of the first joint 11 is re-accommodated in the receiving groove 114, so that the second joint 12 can be separated from the first joint 11.

[0100] By providing the locking member 115 , the second connector 12 can be quickly connected and separated from the first connector 11 , thereby improving the connection efficiency between the second connector 12 and the first connector 11 .

[0101] In some other more specific embodiments, the accommodating groove 114 may also be disposed on the outer wall of the second connector 12 , and the locking groove 124 may be disposed on the inner wall of the first connector 11 .

[0102] Please also refer to Figure 2 and Figure 5 In some more specific embodiments, the receiving groove 114 penetrates the outer wall of the first joint 11. The outer wall of the first joint 11 is movably sleeved with a sliding member 116, and the inner wall of the sliding member 116 is provided with a first step surface 1161 and a second step surface 1162. Both the first step surface 1161 and the second step surface 1162 can contact with the locking member 115, and the first step surface 1161 is closer to the outer wall of the first joint 11 than the second step surface 1162. The sliding member 116 selectively switches the first step surface 1161 or the second step surface 1162 to be opposite to the receiving groove 114, so that the locking member 115 is protruded from the inner wall of the first joint 11 or is accommodated in the receiving groove 114 on the side away from the outer wall of the first joint 11.

[0103] The sliding member 116 may move relative to the first joint 11 , or may rotate relative to the first joint 11 , which is not limited here.

[0104] In this embodiment, during the process of inserting the second connector 12 into the air inlet end 1111 of the first connector 11, the sliding member 116 is firstly in a position where the second step surface 1162 is opposite to the receiving groove 114. At this time, the side of the locking member 115 that is away from the inner wall of the first connector 11 protrudes out of the outer wall of the first connector 11 and abuts against the second step surface 1162. The side of the locking member 115 that is away from the outer wall of the first connector 11 is received in the receiving groove 114, thereby avoiding interference between the locking member 115 and the second connector 12.

[0105] When the slot 124 on the outer wall of the second joint 12 and the receiving slot 114 on the inner wall of the first joint 11 are relative to each other, the sliding member 116 switches to a position where the first step surface 1161 is relative to the receiving slot 114, and the locking member 115 moves to a side away from the inner wall of the first joint 11 and abuts against the first step surface 1161, so that the side of the locking member 115 away from the outer wall of the first joint 11 protrudes out of the inner wall of the first joint 11 and is engaged with the slot 124 on the outer wall of the second joint 12.

[0106] By setting the first step surface 1161 and the second step surface 1162, the side of the locking member 115 away from the inner wall of the first joint 11 can selectively abut the first step surface 1161 and the second step surface 1162, so that the side of the locking member 115 away from the outer wall of the first joint 11 protrudes from the inner wall of the first joint 11 or is accommodated in the accommodating groove 114, thereby reducing the difficulty and complexity of switching the working state of the locking member 115, so that the locking member 115 can quickly lock or unlock the second joint 12.

[0107] In some other more specific embodiments, the receiving groove 114 may also be a blind groove, and the bottom wall of the receiving groove 114 is provided with an elastic component to apply elastic force to the locking member 115 .

[0108] See also Figure 5 In some embodiments, the inner wall of the sliding member 116 is also provided with a slope 1163 that can contact the locking member 115, and the slope 1163 is connected between the first step surface 1161 and the second step surface 1162 to allow the locking member 115 to switch between the first step surface 1161 and the second step surface 1162.

[0109] During the process of inserting the second connector 12 into the air inlet end 1111 of the first connector 11, the sliding member 116 switches from a position where the first step surface 1161 is opposite to the receiving groove 114 to a position where the second step surface 1162 is opposite to the receiving groove 114, and the locking member 115 switches from contacting the first step surface 1161 to contacting the second step surface 1162 via the inclined surface 1163, so that the side of the locking member 115 facing away from the outer wall of the first connector 11 switches from protruding from the inner wall of the first connector 11 to being received in the receiving groove 114.

[0110] When the second connector 12 is inserted into the air inlet end 1111 of the first connector 11 and the clamping groove 124 is opposite to the receiving groove 114, the sliding member 116 switches from the position where the second step surface 1162 is opposite to the receiving groove 114 to the position where the first step surface 1161 is opposite to the receiving groove 114, and the inclined surface 1163 pushes the locking member 115, so that the side of the locking member 115 away from the outer wall of the first connector 11 switches from being accommodated in the receiving groove 114 to protruding from the inner wall of the first connector 11. By providing the inclined surface 1163, the locking member 115 can be smoothly switched between contacting with the first step surface 1161 and contacting with the second step surface 1162, while reducing the complexity of the structure for pushing the locking member 115.

[0111] In some other more specific embodiments, the receiving groove 114 may also be a blind groove, and the bottom wall of the receiving groove 114 is provided with an elastic component to apply elastic force to the locking member 115 .

[0112] Please also read Figure 2 and Figure 5 In some embodiments, the first joint 11 is further provided with a third elastic member 117, the deformation direction of the third elastic member 117 is the same as the direction of movement of the sliding member 116 relative to the first joint 11, and the two ends of the third elastic member 117 respectively abut the sliding member 116 and the first joint 11.

[0113] In this embodiment, the sliding member 116 can move axially relative to the first joint 11 (i.e., the axial direction of the first vent hole 1113), or can rotate around the axial direction of the first joint 11, which is not limited here. Exemplarily, when the sliding member 116 moves relative to the first joint 11, the third elastic member 117 applies a second elastic force along the axial direction of the first joint 11 to the sliding member 116; when the sliding member 116 rotates relative to the first joint 11, the third elastic member 117 applies a second elastic force around the axial direction of the first joint 11 to the sliding member 116.

[0114] During the process of inserting the second connector 12 into the air inlet end 1111 of the first connector 11, the second elastic force is overcome so that the sliding member 116 is in a position relative to the second step surface 1162 and the receiving groove 114. At this time, the side of the locking member 115 facing away from the inner wall of the first connector 11 abuts against the second step surface 1162, and the side of the locking member 115 facing away from the outer wall of the first connector 11 is received in the receiving groove 114.

[0115] When the slot 124 on the outer wall of the second joint 12 and the receiving slot 114 on the inner wall of the first joint 11 are relative to each other, the second elastic force pushes the sliding member 116 to switch to a position where the first step surface 1161 is relative to the receiving slot 114, and the locking member 115 moves to the side away from the inner wall of the first joint 11 and abuts against the first step surface 1161, so that the locking member 115 on the side away from the outer wall of the first joint 11 protrudes out of the inner wall of the first joint 11 and is engaged with the slot 124 on the outer wall of the second joint 12.

[0116] By providing the third elastic member 117 , the complexity of the relative movement between the sliding member 116 and the first joint 11 can be reduced.

[0117] In some other embodiments, the sliding member 116 may also be driven by other driving components.

[0118] See also Figure 6 In a second aspect, the embodiment of the present application further provides an inflatable device 2, comprising the above-mentioned pipeline buffer mechanism 1, a manifold 21 and a plurality of branch pipes 22. The manifold 21 is used to connect the gas source. The plurality of branch pipes 22 are all connected to the manifold 21, the number of the second joints 12 is multiple, and the plurality of second joints 12 are arranged in a one-to-one correspondence with the plurality of branch pipes 22.

[0119] For example, since the structural design of the pipeline 4 of the two components of air conditioners of different models may be different, such as the number and arrangement of the pipeline 4, the inflation device 2 of the prior art is difficult to meet the docking requirements of different pipelines 4. In order to solve this problem, in this embodiment, a plurality of branch pipes 22 are arranged on the manifold 21, and in the initial stage of the inflation process, the pipelines 4 of the two components of air conditioners of different models only need to install the guide pipe 13 and the first joint 11 on the pipeline 4, and then plug the first joint 11 installed on the pipeline 4 with the second joint 12 of one or more branch pipes 22, so that the inflation device 2 of this embodiment can be docked with the pipelines 4 of the two components of air conditioners of different models, thereby expanding the scope of application of the inflation device 2.

[0120] After the pipeline 4 is connected to one or more of the branch pipes 22 , the gas source delivers the protective gas such as nitrogen to the pipeline 4 through the manifold 21 and the branch pipes 22 connected to the pipeline 4 .

[0121] Exemplarily, the branch pipes 22 are numbered from 1 to 20. After the first joint 11 is installed in the two components of the first air conditioner, the first joint 11 can be plugged with the second joints 12 of the branch pipes 22 numbered 1 and 3; after the first joint 11 is installed in the two components of the second air conditioner, the first joint 11 can be plugged with the second joints 12 of the branch pipes 22 numbered 5, 10 and 15.

[0122] In some other embodiments, the inflation device 2 may also be provided with only one branch pipe 22 .

[0123] See also Figure 7 In a third aspect, the present application also discloses an inflation system 3, comprising a positioning mechanism 31, the inflation device 2 as described above, a first actuator (not shown in the figure), and a second actuator 32. The positioning mechanism 31 is used to position the two components. The first actuator is used to install the guide tube 13 and the first connector 11 on the pipeline 4. The second actuator 32 is used to plug the second connector 12 into the air inlet end 1111 of the first connector 11.

[0124] The working principle of this embodiment is that the positioning mechanism 31 positions the two components to prevent the pipeline 4 from being displaced when docking with the inflator 2. After the positioning of the two components is completed, the first actuator first installs the guide tube 13 and the first joint 11 on the pipeline 4, and the second actuator 32 then aligns the second joint 12 with the air inlet end 1111 of the first joint 11. After alignment, the second actuator 32 drives the second joint 12 to move toward the first joint 11, so that the second joint 12 is plugged into the first joint 11.

[0125] The positioning mechanism 31 may be four clamps driven by respective cylinders, and the four clamps can clamp the four sides of the two device components respectively, thereby clamping and positioning the two device components.

[0126] In addition, the inflation system 3 may also include a conveying mechanism, a first detection mechanism, and a second detection mechanism. The conveying mechanism is used to convey the two components, and the first detection mechanism is used to detect whether the two components are conveyed to the preset position. When the first detection mechanism detects that the two components are conveyed to the preset position, the positioning mechanism 31 positions the two components. After the first actuator installs the guide tube 13 and the first joint 11 on the pipeline 4, the second detection mechanism detects the position of the first joint 11, and the second actuator 32 aligns the second joint 12 with the first joint 11 according to the detection result of the second detection mechanism.

[0127] It can be understood that the second detection mechanism and the second actuator 32 can be integrated into the same device, such as a mechanical arm or a robot.

[0128] By means of the above-mentioned charging system 3, the efficiency of charging the pipelines 4 of the two-device components with protective gases such as nitrogen can be improved.

[0129] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention.
