Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, the utility model provides an automobile air conditioner air pipe with a filtering structure, which comprises a connector 1, a middle vent pipe 2 and a side vent pipe;

the middle ventilation pipe 2 and the side ventilation pipe are respectively communicated with the connector 1;

the two side ventilation pipes are respectively and symmetrically arranged at two sides of the connector 1, and each side ventilation pipe comprises a bent pipe 3 and two straight pipes 4; two ends of the bent pipe 3 are respectively communicated with a straight pipe 4; the inner wall of return bend 3 is equipped with at least round groove ring along circumference, is equipped with cake form filtration membrane 5 in the return bend 3, and filtration membrane 5 edge embedding groove intra-annular.

The middle part of at least one end face of the filter membrane 5 is convex, as shown in fig. 1, the filter membrane 5 is provided with a convex part at one end face close to the connector 1, and the design enables the air flow force which can be resisted by the filter membrane 5 to be larger, and the filter membrane is not deformed or broken under the influence of the air flow.

Internal threads are arranged at two ends of the bent pipe 3; one end of the straight pipe 4 is provided with an external thread matched with the internal thread of the bent pipe 3. For the smoothness that the air current passes through, can rationally set up the wall thickness of return bend 3 and straight tube 4, make return bend 3 and straight tube 4 pass through threaded connection after, can smooth transition between return bend 3 and straight tube 4, the air current can not produce the random flow when passing here.

The elbow 3 is composed of two half pipes divided along the central axis thereof; the two half pipe bodies are provided with connecting pieces 6 at the connecting parts and are fixedly connected through the connecting pieces 6. The connecting piece 6 is shown in fig. 1 or 2 and comprises a connecting lug and a connecting bolt; wherein, be equipped with four engaging lugs on every half body at least, and set up in the corresponding position of two half bodies, the setting position is as shown in figure 1. Because the bent pipe 3 can be manufactured by injection molding, namely two half pipe bodies are injected, each half pipe body is correspondingly provided with a connecting lug and a groove half ring (the groove half rings corresponding to the two half pipe bodies form a groove ring), the two half pipe bodies are combined to form a complete bent pipe 3, and the corresponding connecting lugs are connected through connecting bolts. Of course, for the present invention, before the two half-tubes are combined, the filtering membrane 5 needs to be inserted into the corresponding groove ring and then combined. The elbow 3 is simple in structure and convenient to manufacture, the filtering membrane 5 is not easy to fall off, and in order to ensure the sealing property of the elbow 3 at the joint of the two half pipes, sealant can be coated at the joint of the two half pipes. In order to ensure the stable connection of the filtering membrane 5, glue can be dripped at the bottom of the groove ring to ensure that the filtering membrane 5 is better fixed in the groove ring.

Of course, the filtering membrane 5 can be arranged in the middle ventilating pipe 2, and the arrangement form can be the same as that of the filtering membrane 5 in the side ventilating pipe, and since the transfer of the means is easy to be completed by common knowledge without creative labor of a person skilled in the art, the detailed description of how to arrange the filtering membrane 5 in the middle ventilating pipe 2 is not provided in the embodiment.

Through the action of the filter membrane 5, dust entering the middle ventilation pipe 2 or the side ventilation pipes from the connector 1 can be effectively filtered. In addition, the filtering membrane 5 plays a role in slowing down the impact force of the airflow to a certain extent, and the air-conditioning air pipe is protected from being broken due to the impact of strong airflow.
