DETAILED DESCRIPTION
[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.
[0029] The air conditioner provided in the embodiment of the utility model is as follows Figures 1 to 8 As shown, it includes a refrigerant connecting pipe 100 and a branch box. Figures 1 to 8 As shown, the branch box includes: a box body 210, a side wall of which is provided with a through hole 211; a main body 220, the main body 220 is provided with an interface pipe 222, the main body 220 is arranged in the box body 210, the interface pipe 222 is penetrated through the through hole 211 and extends out of the box body 210; and a bellows 230, the bellows 230 is located outside the box body 210 and is sleeved on the interface pipe 222, and one end of the bellows 230 adjacent to the box body 210 is connected to the hole wall of the through hole 211 The bellows 230 is sealed, and one end of the bellows 230 away from the box 210 is configured to be stretched to the side of the interface tube 222 away from the box 210. There is a communication channel 240 between the bellows 230 and the interface tube 222. The communication channel 240 is connected to the space between the box 210 and the main body 220 through the hole 211; and the refrigerant detection device 221 is located in the space between the box 210 and the main body 220. Among them, as Figures 1 to 5 , Figure 8As shown, the refrigerant connecting pipe 100 is located outside the box body 210 and is connected to the interface pipe 222. The end of the bellows 230 away from the box body 210 is stretched to the side of the interface pipe 222 away from the box body 210, so as to be sleeved outside the refrigerant connecting pipe 100 and sealed with the refrigerant connecting pipe 100. The position where the refrigerant connecting pipe 100 and the interface pipe 222 are connected is located inside the bellows 230.
[0030] In the air conditioner, the bellows 230 is located outside the housing 210 and is sleeved on the interface pipe 222. The refrigerant connecting pipe 100 is located outside the housing 210 and is connected to the interface pipe 222. The end of the bellows 230 adjacent to the housing 210 is sealed with the hole wall of the through hole 211. The end of the bellows 230 away from the housing 210 is stretched to the side of the interface pipe 222 away from the housing 210 to be sleeved outside the refrigerant connecting pipe 100 and sealed with the refrigerant connecting pipe 100. The position where the refrigerant connecting pipe 100 and the interface pipe 222 are connected is located inside the bellows 230. A connecting passage 240 is provided between the bellows 230 and the interface pipe 222. The end of the connecting passage 240 adjacent to the housing 210 is The space between the box body 210 and the main body 220 is connected through the hole 211, and the other end of the connecting channel 240 is closed. The refrigerant detection device 221 is located in the space between the box body 210 and the main body 220. When the refrigerant leaks at the position where the refrigerant connecting pipe 100 and the interface pipe 222 are connected, the leaked refrigerant enters the space between the box body 210 and the main body 220 along the connecting channel 240 through the hole 211, and the refrigerant is prevented from diffusing into the room. Therefore, it is less likely to cause a fire indoors. Moreover, when there is refrigerant in the space between the box body 210 and the main body 220, the refrigerant detection device 221 can detect it in time, which is conducive to the air conditioner to make corresponding processing in time (the corresponding processing includes outputting alarm information, etc.). Wherein, the refrigerant is a combustible refrigerant or a non-combustible refrigerant.
[0031] In one embodiment, if Figure 2 and Figure 5 As shown, the refrigerant detection device 221 is arranged on the main body 220 and is set as a refrigerant detection sensor. The refrigerant detection sensor technology is mature and easy to purchase. Preferably, the space between the box body 210 and the main body 220 is set as a closed space.
[0032] In some examples, such as Figure 6 and Figure 7As shown, the bellows 230 includes a connecting section 231, a corrugated section 232 and a constricted section 233 connected in sequence, the connecting section 231 is configured to seal with the hole wall of the through hole 211, the constricted section 233 is located on the side of the corrugated section 232 away from the box body 210, and the constricted section 233 is configured to seal with the refrigerant connecting pipe 100. The material of the bellows 230 can be set to silicone, rubber, plastic, etc., which can achieve the purpose of this application, and its purpose does not deviate from the design concept of the utility model, and will not be repeated here, and should all fall within the protection scope of this application.
[0033] In one embodiment, if Figure 6 and Figure 7 As shown, the outer peripheral surface of the connecting section 231 is provided with an annular slot 2311, and the hole wall of the through hole 211 is sealed and inserted into the annular slot 2311. A first gap is provided between the connecting section 231 and the interface pipe 222, and the communication channel 240 is communicated with the space between the box body 210 and the main body 220 through the first gap. In this solution, the connecting section 231 has a simple structure and is convenient to be inserted into the through hole 211 and to be plugged and sealed with the hole wall of the through hole 211.
[0034] In one embodiment, if Figure 6 and Figure 7 As shown, the peripheral wall of the constricted section 233 is provided with a slit 2331 extending along the axial direction of the constricted section 233, and one end of the slit 2331 away from the corrugated section 232 is through, so that the constricted section 233 is more easily stretched to be sleeved outside the refrigerant connecting pipe 100. Furthermore, the air conditioner further comprises a clamp 250, which seals and tightens the constricted section 233 to the refrigerant connecting pipe 100 to close the slit 2331 and the gap between the constricted section 233 and the refrigerant connecting pipe 100, thereby ensuring reliable sealing at the constricted section 233.

When a refrigerant leaks from the position where the refrigerant connecting pipe 100 and the interface pipe 222 are connected, the leaked refrigerant diffuses from both ends of the heat-insulating layer 260 to the connecting channel 240, and then enters the space between the box body 210 and the main body 220 from the connecting channel 240 through the first gap. Figure 4 , Figure 6 and Figure 7As shown, since the peripheral wall of the necked section 233 is provided with a slit 2331 , after the insulation layer 260 is arranged outside the interface pipe 222 inside the bellows 230 and the refrigerant connecting pipe 100 , the necked section 233 can easily pass through the insulation layer 260 .
[0036] The insulation layer 260 may be configured as a silicone sleeve or a rubber sleeve or insulation cotton, etc., all of which can achieve the purpose of this application. The purpose does not deviate from the design concept of the utility model and will not be repeated here. They should all fall within the protection scope of this application.

[0038] In one embodiment, if Figures 1 to 5 , Figure 8 As shown, the interface pipe 222 includes an external interface pipe and an internal interface pipe, the through hole 211 includes a first through hole and a second through hole, the bellows 230 includes a first bellows 2301 and a second bellows 2302, the external interface pipe is passed through the first through hole, the first bellows 2301 is sleeved on the external interface pipe and is sealed with the first through hole, the internal interface pipe is passed through the second through hole, the second bellows 2302 is sleeved on the internal interface pipe and is sealed with the second through hole. Figure 2 and Figure 5 As shown, the first through hole and the second through hole are disposed on a group of adjacent side walls of the box body 210, and the refrigerant detection device 221 is located at an angle formed by the group of adjacent side walls.

One end of the channel adjacent to the box is connected to the space between the box and the main body through a through hole, and the other end of the connecting channel is closed. The refrigerant detection device is located in the space between the box and the main body.
