[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. The features specified as "first" and "second" may explicitly or implicitly include one or more features. In the description of this utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0034] Please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, this embodiment provides an air-conditioning muffler, which is connected in series in the air-conditioning pipeline of the air conditioner; specifically, the air-conditioning muffler includes a connecting sleeve 11, an inlet pipe 12, an outlet pipe 13 and a muffler cavity 14 connecting the inlet pipe 12 and the outlet pipe 13; wherein, the outer wall of the inlet pipe 12 is provided with a tray structure 121 extending outward, and one end of the connecting sleeve 11 is provided with a first limiting structure 111, the first limiting structure 111 extends toward the outside of the pipe along the pipe diameter direction of the connecting sleeve 11, and the tray structure 121 abuts against the first limiting structure 111; the connecting sleeve 11 is plugged into the inlet pipe 12 and is fixedly connected to the tray structure 121 through the first limiting structure 111; the connecting sleeve 11 is also used to connect to the air-conditioning pipeline, and is welded and fixed to the air-conditioning pipeline through the inner wall of the connecting sleeve 11.

[0035] In this embodiment, the air-conditioning pipeline portion welded to the connecting sleeve 11 is one end of the air-conditioning pipeline, recorded as the first air-conditioning pipeline section 20, and the other end of the air-conditioning pipeline is recorded as the second air-conditioning pipeline section 30. The second air-conditioning pipeline section 30 can be connected to the air-conditioning muffler through the outlet pipe 13 and welded and fixed, so that the air-conditioning muffler is connected in series in the air-conditioning pipeline.

[0036] The connecting sleeve 11 is a copper tube, the air conditioning pipeline connected to the connecting sleeve 11 is a stainless steel pipeline, and the inlet pipe 12, outlet pipe 13, and muffler chamber 14 are an integrally formed stainless steel structure; the second air conditioning pipeline section 30 connected to the outlet pipe 13 can be a copper pipeline section. In this embodiment, by providing the connecting sleeve 11 and providing a tray structure 121 at the outlet of the inlet pipe 12, the connecting sleeve 11 is used to securely connect the air conditioning muffler and the air conditioning pipeline. This reduces the structural requirements for the connection between the inlet pipe 12 and the air conditioning pipeline in the air conditioning muffler, thereby facilitating the connection between the air conditioning pipeline and the air conditioning muffler.

[0037] Among them, the connecting sleeve 11 and the inlet pipe 12 can be fixed by welding; because the connecting sleeve 11 and the inlet pipe 12 are fixed and welded using the tray structure 121, and the connecting sleeve 11 is connected to the inlet pipe 12 outside the inlet pipe 12, it can prevent welding slag from falling into the silencer cavity 14; and, because the outer wall of the inlet pipe 12 and the connecting sleeve 11 are welded and fixed, the operation is convenient, the internal structure requirements of the inlet pipe 12 are low, and it is more conducive to welding.

[0038] Please continue reading Figure 2 In some embodiments, the other end of the connecting sleeve 11 has a second limiting structure 112, which extends into the pipe along the pipe diameter direction of the connecting sleeve 11; the second limiting structure 112 is used to limit the insertion depth of the air-conditioning pipeline; in this embodiment, by setting the second limiting structure 112, the insertion depth of the first air-conditioning pipeline section 20 can be effectively limited, thereby ensuring the insertion depth of the first air-conditioning pipeline section 20, so as to improve the connection stability with the air-conditioning pipeline.

[0039] In some embodiments, the first limiting structure 111 includes an abutting portion 101 and a limiting portion 102 connected to the abutting portion 101; the abutting portion 101 is located at one end of the connecting sleeve 11 and extends toward the outside of the pipe along the pipe diameter direction of the connecting sleeve 11; the limiting portion 102 extends toward the silencer cavity 14 along the depth direction of the connecting sleeve 11; that is, in this embodiment, the abutting portion 101 and the limiting portion 102 are set, and combined with the outer wall surface of the connecting sleeve 11 to form a snap-fit position; when the connecting sleeve 11 is inserted into the inlet pipe 12, the end of the inlet pipe 12 is inserted into the snap-fit position and abuts against the abutting portion 101, which on the one hand limits the access position of the connecting sleeve 11, and on the other hand can also improve the stability of the connection between the connecting sleeve 11 and the inlet pipe 12.

[0040] Please also refer to Figure 5 and Figure 6 In some embodiments, the tray structure 121 is used to abut against the limiting portion 102 when the connecting sleeve 11 is inserted into the inlet pipe 12; in this embodiment, by providing the tray structure 121 so as to abut against the limiting portion 102 of the connecting sleeve 11, the contact area between the connecting sleeve 11 and the inlet pipe 12 can be increased, that is, the welding fixing surface is increased, thereby improving the connection stability of the connecting sleeve 11 and the inlet pipe 12.

[0041] In some embodiments, a groove 122 adapted to the limiting portion 102 is provided in the tray structure 121; the groove 122 is used to insert the limiting portion 102; when the connecting sleeve 11 is inserted into the inlet pipe 12, the limiting portion 102 can be simultaneously inserted into the groove 122 in the tray structure 121 for welding and fixing, so as to further improve the connection stability between the connecting sleeve 11 and the inlet pipe 12.

[0042] As an embodiment, the groove 122 in the tray structure 121 is an annular groove; the limiting portion 102 is an annular structure surrounding the outer wall of the inlet pipe 12; correspondingly, the abutting portion 101 is an annular structure surrounding the outer wall of the end of the inlet pipe 12. Thus, it is equivalent to forming an annular groove at the end of the connecting sleeve 11 and forming an annular groove on the outer wall of the inlet pipe 12; when the connecting sleeve 11 is inserted into the inlet pipe 12, the annular groove of the connecting sleeve 11 is used to accommodate the inlet pipe 12, and the annular groove in the inlet pipe 12 is used to accommodate the limiting portion 102, so that the connecting sleeve 11 and the inlet pipe 12 are mutually engaged, which is conducive to the stability of the connection between the connecting sleeve 11 and the inlet pipe 12.

[0043] As an embodiment, the second limiting structure 112 is an annular structure forming a platform; when the first air-conditioning pipe section 20 is inserted into the connecting sleeve 11, the first air-conditioning pipe section 20 can be supported and connected by the second limiting structure 112, which not only limits the insertion depth of the first air-conditioning pipe section 20, but also facilitates the stability of the connection.

[0044] Please also refer to Figure 7 As an embodiment, the inlet pipe 12 gradually widens toward the silencer cavity 14 connected thereto to form a first gradient section 15; when the air-conditioning silencer is connected in series with the air-conditioning pipeline, the refrigerant in the air-conditioning pipeline enters from the inlet section and then passes through the variable diameter section. As the flow channel of the variable diameter section gradually expands, the refrigerant pressure is gradually reduced, thereby eliminating the pressure vibration. After the refrigerant enters and passes through the silencer section, the flow velocity and pressure are both reduced to a reasonable level, and the refrigerant flow noise and pipeline vibration are reduced to a certain extent, thereby reducing the refrigerant flow noise and improving the noise elimination effect.

[0045] As an embodiment, the silencer cavity 14 connected to the outlet pipe 13 in the air-conditioning silencer gradually narrows toward the outlet pipe 13 to form a second gradient section 16; when the air-conditioning pipeline flows out of the silencer section and then passes through the variable diameter section, the flow channel of the variable diameter section gradually narrows, which facilitates the collection of refrigerant and makes it flow out of the silencer section, so that the refrigerant pressure is gradually reduced, thereby eliminating the pressure vibration; then after the refrigerant enters and passes through the outlet section, the flow rate and pressure are reduced to a reasonable level, and the refrigerant flow noise and pipeline vibration are reduced to a certain extent, thereby reducing the refrigerant flow noise and improving the noise elimination effect.

[0046] An embodiment of the present application also provides an air conditioner, which includes an air-conditioning pipeline and an air-conditioning muffler, which is connected in series with the air-conditioning pipeline; the air-conditioning muffler in this embodiment is provided with a connecting sleeve and a tray structure at the inlet pipe, and the air-conditioning muffler and the air-conditioning pipeline are fixedly connected by the connecting sleeve, which can reduce the structural requirements for the connection between the inlet pipe and the air-conditioning pipeline in the air-conditioning muffler, so as to facilitate the connection between the air-conditioning pipeline and the air-conditioning muffler.
