Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0036] Reference Figures 1 to 3 According to a first aspect embodiment of the present invention, a needle valve fixing structure includes a gas pipe 100, a needle valve 200, and a fixing assembly 300. The gas pipe 100 is disposed inside an air conditioner and is used to transport gaseous refrigerant. Of course, the application of the gas pipe 100 is not limited to air conditioners; it can also be disposed in other refrigeration or heating equipment with a compressor. The needle valve 200 is disposed outside the gas pipe 100 and has a connecting end 210 and an injection end 220. The connecting end 210 communicates with the gas pipe 100, and the injection end 220 allows fluid to be injected into the needle valve 200 to ensure that the valve remains in place even when no refrigerant is replenished. The needle valve 200 and the air pipe 100 are sealed. The injection end 220 of the needle valve 200 is normally closed. When the refrigerant in the air conditioner is reduced due to leakage or other reasons, and refrigerant needs to be added to the air conditioner, the operator can open the injection end 220 of the needle valve 200 and inject the refrigerant from the injection end 220 into the needle valve 200. The refrigerant in the needle valve 200 flows into the air pipe 100 through the connection end 210. The fixing component 300 is set between the air pipe 100 and the needle valve 200, and the fixing component 300 is usually set at the end of the needle valve 200 away from the air pipe 100. The fixing component 300 can fix the needle valve 200 relative to the air pipe 100.

[0037] By adopting the above structure, a fixing component 300 is provided between the air pipe 100 and the needle valve 200. The fixing component 300 can fix the exposed valve body of the needle valve 200 relative to the air pipe 100. Compared with the traditional needle valve 200 that is only connected to the air pipe 100 at one end, the additional fixing component 300 between the needle valve 200 and the air pipe 100 can fix and protect the needle valve 200, and minimize the risk of the needle valve 200 shifting, deforming, breaking or falling off due to force during air conditioning assembly, movement, operation and maintenance.

[0038] It should be noted that in this embodiment, the needle valve 200 is L-shaped, with the shorter end being the connection end 210 and the longer end being the injection end 220, which faces upwards. This makes the needle valve 200 more compact and saves installation space. At the same time, the upward-facing injection end 220 allows operators to more intuitively and easily approach the injection end 220 to replenish the refrigerant without complicated body positioning or the use of additional auxiliary tools. Of course, depending on actual needs, the needle valve 200 can also be designed as an arc, S-shape, or other shapes that optimize space utilization and improve operational convenience to meet different installation conditions.

[0039] It should be noted that the fixing component 300 can be an elastic element. Specifically, the fixing component 300 can be a rubber part. Thus, the fixing component 300 can reduce vibration of the needle valve 200 while minimizing the risk of displacement, deformation, breakage or detachment of the needle valve 200 under stress.

[0040] Reference Figures 1 to 3 In some embodiments of this utility model, the fixing component 300 includes a fixing member 301, one end of which is connected to the needle valve 200, and the other end of which is connected to the air tube 100.

[0041] It should be noted that the fastener 301 is a block structure. The fastener 301 is placed between the needle valve 200 and the air tube 100. The fastener 301 can fill the gap between the needle valve 200 and the air tube 100, thereby fixing the needle valve 200 relative to the air tube 100. In addition, depending on the actual needs, the fastener 301 can also be a plate structure or a sheet structure.

[0042] It is understood that the connection between the fastener 301 and the needle valve 200 or the air tube 100 can be an abutment connection, a snap-fit ​​connection, an adhesive connection, a welding connection or other connections, and this utility model does not specifically limit this.

[0043] Reference Figure 1 and Figure 2In some embodiments of this utility model, the fixing member 301 has a mounting hole 310, the diameter of which corresponds to the diameter of the needle valve 200, and the mounting hole 310 penetrates the fixing member 301. During the assembly process of the air tube 100, the needle valve 200 and the fixing member 301, the connecting end 210 of the needle valve 200 is first connected to the air tube 100, and then the needle valve 200 is inserted into the mounting hole 310. The end of the fixing member 301 away from the needle valve 200 is connected to the air tube 100.

[0044] By adopting the above structure, the mounting hole 310 on the fixing member 301 can make the connection between the fixing member 301 and the needle valve 200 more stable. The fixing member 301 can better protect the needle valve 200 and prevent the needle valve 200 from shifting, deforming, breaking or falling off during the assembly, movement, operation and maintenance of the air conditioner.

[0045] It should be noted that in some embodiments of this utility model, the injection end 220 of the needle valve 200 has a detachable structure. During the installation of the fixing member 301, the diameter of the injection end 220 of the needle valve 200 is larger than the diameter of the mounting hole 310. The detachable structure of the injection end 220 can be removed first so that the valve body of the needle valve 200 can be smoothly inserted into the mounting hole 310, and then the detachable structure of the injection end 220 can be reinstalled.

[0046] It is understood that when the needle valve 200 is inserted into the mounting hole 310, the connection between the end of the fixing member 301 away from the needle valve 200 and the air tube can be an abutment connection, a snap-fit ​​connection, an adhesive connection, a welding connection or other connections, and this utility model does not make specific limitations in this regard.

[0047] Reference Figure 1 and Figure 3 In some embodiments of this utility model, the fixing member 301 has a receiving cavity 320, and the fixing member 301 also has an opening 330 for the needle valve 200 to enter and exit the receiving cavity 320; when the fixing member 301 is connected to the needle valve 200, the needle valve 200 is embedded in the receiving cavity 320.

[0048] By adopting the above structure, during the assembly process of the air tube 100, needle valve 200 and fixing member 301, the fixing member 301 can be installed and connected to the air tube 100 first or the needle valve 200 can be installed and connected to the air tube 100 first, providing more choices for the installation sequence. The needle valve 200 is embedded in the receiving cavity 320, and the fixing member 301 is detachably installed on the valve body of the needle valve 200. The fixing member 301 is easy to disassemble, and the installation is simple and quick, which facilitates the daily use and maintenance of the needle valve 200.

[0049] It should be noted that when the needle valve 200 is installed in the receiving cavity 320, the connection between the needle valve 200 and the receiving cavity 320 can be an interference fit connection, which makes the installation more stable. The receiving cavity 320 and the opening 330 can be elastic, which makes it easier for the needle valve 200 to enter and exit the receiving cavity 320, and the receiving cavity 320 can be adapted to needle valves 200 of various sizes.

[0050] It is understood that when the needle valve 200 is installed in the receiving cavity 320, the connection between the end of the fixing member 301 away from the needle valve 200 and the air tube can be an abutment connection, a snap-fit ​​connection, an adhesive connection, a welding connection or other connections, and this utility model does not make specific limitations in this regard.

[0051] Reference Figures 1 to 3 In some embodiments of this utility model, the end of the fixing member 301 away from the needle valve 200 is engaged or abutted against the air tube 100; the fixing component 300 also includes a binding member, which can bind the air tube 100 and the fixing member 301 together, or the binding member can bind the air tube 100, the needle valve 200 and the fixing member 301 together.

[0052] By adopting the above structure, when the fixing member 301 and the air tube 100 are connected by snap-fit ​​or abutment, the binding member can further make the connection between the fixing member 301 and the air tube 100 more stable. The binding member is easy to install and remove, so the fixing member 301 can be installed and removed conveniently and quickly, meeting the daily use and maintenance needs of the needle valve 200.

[0053] In some embodiments of this utility model, the binding element is a cable tie.

[0054] Cable ties are the most common type of binding material. They are self-locking and fasten quickly and easily. Cable ties are typically made of nylon-66, a material that has excellent acid and corrosion resistance, insulation, and is not prone to aging. It also has high strength and is safe and non-toxic.

[0055] Reference Figures 1 to 3 In some embodiments of this utility model, the side wall of the fixing member 301 has a groove 340 that can accommodate the binding member. When the binding member binds the fixing member 301 and the air tube 100 together, at least part of the binding member is embedded in the groove 340.

[0056] By adopting the above structure, at least part of the binding component is embedded in the groove 340. The groove 340 can accommodate and fix the binding component, so that the binding component is not easy to slide up and down and get off the fixing component 301 during binding, which would cause binding failure. At the same time, the groove 340 can also play a positioning role, placing part of the binding component in the groove 340. The periphery of the groove 340 is perpendicular to the axis of the air tube 100. The groove 340 can make the binding component bind along the direction perpendicular to the axis of the air tube 100, making the binding more secure and the binding component less likely to loosen.

[0057] It should be noted that the width of the groove 340 corresponds to the width of the binding component. Therefore, when part of the binding component is embedded in the groove 340, the binding component is less likely to loosen within the groove 340, resulting in a better binding effect.

[0058] Reference Figure 5 and Figure 6 In some embodiments of this utility model, the side wall of the trachea 100 has an installation port 110. In this embodiment, the periphery of the installation port 110 has a protruding structure facing the outside of the trachea 100, and the connecting end 210 is inserted into the installation port 110 and sealed to the trachea 100.

[0059] By adopting the above structure, the needle valve 200 can be installed on the side wall of the trachea 100, and the protruding structure around the mounting port 110 can increase the contact area of ​​the connection between the trachea 100 and the needle valve 200, making the connection between the needle valve 200 and the trachea 100 more stable, and the needle valve 200 is less likely to loosen or detach from the trachea 100.

[0060] It is understandable that, in order to meet the requirements of a sealed connection, the connection between the connection end 210 and the mounting port 110 is usually an interference fit connection. Of course, depending on the actual needs, welding connection, adhesive connection or other sealing connection methods can also be used. This utility model does not make specific limitations on this.

[0061] Reference Figure 4 In some embodiments of this utility model, the side wall of the connecting end 210 has a limiting part 211. In this embodiment, the limiting part 211 is circular in shape, and the diameter of the limiting part 211 is larger than the diameter of the mounting port 110. The limiting part 211 can abut against the mounting port 110 and limit the depth of the connecting end 210 inserted into the trachea 100.

[0062] By adopting the above structure, the depth of the connection end 210 inserted into the air tube 100 can be limited by setting the limiting part 211, thereby ensuring the normal injection of fluid without affecting the normal operation of the air tube 100. The limiting part 211 can also play a positioning role for the needle valve 200. By adjusting the position of the limiting part 211, the distance of the needle valve 200 inserted into the air tube 100 is relatively fixed. At this time, the interval between the needle valve 200 and the air tube 100 is also relatively fixed, so that the fixing component 300 can be installed better in the interval between the needle valve 200 and the air tube 100.

[0063] An air conditioner according to a second aspect of the present invention includes an air conditioner body, the air conditioner body being configured with a needle valve fixing structure as described in the above embodiment.

[0064] The air conditioner of this utility model adopts the needle valve fixing structure of any of the above embodiments, and a fixing component 300 is provided between the gas pipe 100 and the needle valve 200. The fixing component 300 can fix the exposed valve body of the needle valve 200 relative to the gas pipe 100. Compared with the traditional needle valve 200 that is only connected to the gas pipe 100 at one end, the additional fixing component 300 between the needle valve 200 and the gas pipe 100 can fix and protect the needle valve 200, and minimize the risk of the needle valve 200 shifting, deforming, breaking or falling off during the assembly, movement, operation and maintenance of the air conditioner.

[0065] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
