In addition, the connecting piece 1 is covered on the outlet 31, so that on one hand, insects, mice and the like can be further prevented from entering the air conditioner through the outlet 31 directly because the outlet 31 is covered by the connecting piece 1, and on the other hand, the outlet 31 is covered, so that the outlet 31 is large enough to be opened without worrying about entering insects, and the pipeline connection is ensured to have enough operation space and avoid the risk of being flattened.

The fixing piece 2 is provided with a plurality of fixing holes 211 for the liquid inlet and outlet pipes to pass through, and the fixing holes 211 have different apertures to adapt to the liquid inlet and outlet pipes with different pipe diameters. That is, a plurality of fixing holes 211 with different apertures may be provided in advance on the fixing member 2, and when the liquid inlet and outlet pipe is installed, the liquid inlet and outlet pipe can be selected from which fixing hole 211 is penetrated according to the pipe diameter of the liquid inlet and outlet pipe, so that the pipe diameter of the liquid inlet and outlet pipe and the aperture of the fixing hole 211 can be maximally ensured to be matched, that is, the liquid inlet and outlet pipe can smoothly penetrate through the fixing hole 211, and the gap between the liquid inlet and outlet pipe and the fixing hole 211 can be maximally ensured to be minimum.

The technical scheme provided by the embodiment of the disclosure can comprise the following beneficial effects: in the connection pipe structure provided by the disclosure, the fixing piece is provided with a plurality of fixing holes 211 for the liquid inlet and outlet pipes to pass through, and the fixing holes 211 have different apertures to adapt to the liquid inlet and outlet pipes with different pipe diameters, namely, the fixing holes 211 with different apertures can be selected according to the actually used liquid inlet and outlet pipes, so that the universality of the connection pipe structure is improved. For example, the pipe diameter of the liquid inlet and outlet pipe is matched with the aperture of the fixing hole 211, so that a larger gap between the fixing hole 211 and the liquid inlet and outlet pipe can be avoided to the greatest extent, the risks of insect inlet and mouse inlet in the air conditioner are reduced, and the use safety of the air conditioner is improved. And the connecting piece 1 cover is established on the exit opening 31 of indoor set, can provide the protection for the inside connecting pipe of connecting piece 1, can also further avoid worm and mouse directly to get into the air conditioner inside through exit opening 31 simultaneously, and because exit opening 31 is covered, can make exit opening 31 not worry enough big of seting up under the circumstances of entering the worm, guarantee that the pipeline connection has sufficient operating space and avoid the risk of being flattened.

In some embodiments, as shown in fig. 3, the fixing member 2 is made of an elastic material, for example, may be injection molded using a rubber material, and the fixing member 2 is provided with a plurality of notches 212 extending radially from the edge of the fixing member 2 to the fixing hole 211. During installation, the liquid inlet and outlet pipe is pressed into the fixing hole 211 along the radial direction through the notch 212, specifically, since the fixing piece 2 is made of elastic materials, the notch 212 has a certain deformability, when the liquid inlet and outlet pipe is installed, the notch 212 expands to facilitate the liquid inlet and outlet pipe to be pressed into the fixing hole 211, and the liquid inlet and outlet pipe is narrowed again under the action of elastic restoring force to avoid the liquid inlet and outlet pipe from falling out. Further, the notch 212 may be configured in a slit shape, and the opening width of the notch 212 may be 0.4 to 0.6 mm. The gap 212 in this range is smaller in width when not deformed by distraction to facilitate avoiding insect and mouse feeding. In other embodiments, the fixing member 2 may be made of elastic plastic, and the notch 212 may be an open circular arc shape, and the notch 212 may be slightly smaller than the pipe diameter of the liquid inlet pipe and the liquid outlet pipe.

Since the fixing member 2 is previously provided with the plurality of fixing holes 211 having different apertures in order to improve the versatility of the connection pipe structure, the connection pipe structure may further include a sealing member for sealing the gap 212 after the liquid inlet and outlet pipe is mounted to the fixing hole 211, for example, an adhesive tape for sealing the gap 212 or a rubber plug having a shape adapted to the gap 212 in order to prevent insects and mice from entering the air conditioner through the remaining fixing holes 211 or the gap 212 after the liquid inlet and outlet pipe is mounted to the fixing hole 211.

As a way of enabling the connection of the connection member 1 with the fixing member 2, in some embodiments, referring to fig. 3 and 4 together, the inner peripheral surface of the second end of the connection member 1 is provided with a flange 11, and the outer peripheral surface of the fixing member 2 is provided with a catching groove 221 for cooperation with the flange 11 to prevent the fixing member 2 from coming out. Further, the inner peripheral surface of the second end of the connector 1 may be provided with a locking groove 221, and the outer peripheral surface of the fixing member 2 may be provided with a flange 11. When the connector is mounted, the fixing member 2 is pressed into the inner peripheral surface of the second end of the connector 1 with a small force, and the flange 11 and the clamping groove 221 can be in locking fit under the action of elastic deformation force. In addition, other types of mating methods, such as an interference fit or a snap fit, can be applied in the present disclosure to achieve the connection between the connector 1 and the fixing member 2, which will not be described herein.
