[0002] At present, in many application scenarios, it is necessary to supply air or adjust the temperature of the target area. Generally, the air duct is connected to the air outlet of the device with air supply function or the air conditioner through the pipe fitting, and then the user holds the air duct and aims it at the target area to supply air or adjust the temperature. In the prior art, the air duct and the pipe fitting are generally fixed by plug-in or threaded connection. Although this fixing method can provide a stable connection effect, it may bring safety hazards in some special scenarios. For example, in the scenario of outdoor high-altitude operation, the pipe fitting may be pulled by external force due to unexpected circumstances. At this time, the pipe fitting cannot be separated from the air duct, which will further drive the air duct, and the air duct drives the user, causing the user to fall into an unbalanced state in a difficult to prevent situation, bringing safety hazards.

[0028] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0030] In the description of the present invention, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In some embodiments, an air inlet 001 is provided at one end of the wind tube, and a magnet 002 is installed at the air inlet 001, and an air outlet 003 is provided at the other end of the wind tube. When in use, the air inlet 001 is connected to a pipe equipped with a magnetic joint, and the magnet 002 at the air inlet 001 and the magnetic joint are attracted by magnetic force, so that the air inlet 001 and the magnetic joint are stably connected, and the user can hold the wind tube to operate. In actual application, when the pipe is pulled by a large external force, the magnetic joint can fall off from the air inlet 001 by itself, solving the technical problem in the prior art that the pipe is difficult to separate from the wind tube when pulled by an external force. Avoid the safety hazard caused by the wind tube being pulled by the pipe and then driving the user.

[0033] In some embodiments, the magnet 002 is a ring magnet 002, which does not require calibration when connected to a pipe equipped with a magnetic joint, thereby improving work efficiency.

[0034] In some embodiments, the wind cylinder includes a cylindrical outer cylinder 100 and an inner cylinder 200, one end of the outer cylinder 100 has a first opening 110, and the air inlet 001 is located on the end surface of the other end of the outer cylinder 100. The outer diameter of the annular magnet 002 matches the inner diameter of the outer cylinder 100, which is 1 mm smaller than the inner diameter of the outer cylinder 100, but larger than the aperture of the air inlet 001. One end of the inner cylinder 200 has a second opening 210, one end of the inner cylinder 200 is inserted into the outer cylinder 100 from the first opening 110, and the annular magnet 002 is fixed at the air inlet 001. The air outlet 003 is located at the other end of the inner cylinder 200, and a third opening 120 is opened on the outer cylinder 100 at a position corresponding to the air outlet 003. When in use, firstly place the annular magnet 002 in the outer cylinder 100 through the first opening 110 and place it at the air inlet 001. Since the outer diameter of the annular magnet 002 matches the inner diameter of the outer cylinder 100 and is larger than the aperture of the air inlet 001, it will be restricted by the inner wall of the other end face of the outer cylinder 100 and will not escape from the air inlet 001. Then, insert one end of the inner cylinder 200 into the outer cylinder 100 through the first opening 110 until the end of one end of the inner cylinder 200 abuts against the magnet 002, and the magnet 002 is fixed at the air inlet 001.

[0035] It should be noted that Figure 2 and Figure 4 The air outlet 003 shown is located on the side wall of the other end of the inner cylinder 200, and the third opening 120 partially overlaps with the first opening 110. The air outlet 003 can also be set on the end surface of the other end of the inner cylinder 200, in which case the third opening 120 and the first opening 110 are the same opening. The air outlet 003 can also be set at other positions on the side wall of the inner cylinder 200, in which case the third opening 120 and the first opening 110 are independent of each other.

[0036] Furthermore, a buckle 211 is disposed at the second opening 210, and a slot 130 matching the buckle 211 is provided on the inner wall of the other end of the outer cylinder 100. When in use, one end of the inner cylinder 200 is inserted into the outer cylinder 100 from the first opening 110 until the buckle 211 is snapped into the slot 130, so that the positions of the inner cylinder 200 and the outer cylinder 100 are fixed, and the edge of the first opening 110 and the inner wall of the outer cylinder 100 form a groove, and the annular magnet 002 is fixed in the groove. It can be understood that the buckle 211 matches the slot 130 means that the shapes of the two are adapted and the positions are corresponding.

[0037] Furthermore, a protrusion 220 is provided on the outer wall of the inner cylinder 200, and a guide groove 140 is provided on the inner wall of the outer cylinder 100 along its axial direction, and the protrusion 220 matches the guide groove 140. When in use, one end of the inner cylinder 200 is inserted into the outer cylinder 100 from the first opening 110, and the protrusion 220 is embedded in the guide groove 140 during the insertion process, which facilitates the alignment of the buckle 211 and the slot 130, thereby improving work efficiency.

[0038] In some embodiments, the air outlet 003 is located on the side wall at the other end of the air duct. After the airflow flows into the air duct through the air inlet 001, it will be blocked by the inner wall of the end surface at the other end of the air duct, and then flow out through the air outlet 003 after turning. After the airflow is blocked, it will be buffered, and its wind pressure will be reduced when it flows out of the air outlet 003, which is used to meet the application scenarios that require the use of soft airflow.

[0039] In some embodiments, a grille 004 is provided at the air outlet 003 to prevent foreign matter from entering the air duct through the air outlet 003 .

[0040] Furthermore, the grille 004 is wavy in shape, so as to further improve the effect of preventing foreign matter from entering the air duct.

[0041] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention. The scope of the present invention is defined by the claims and their equivalents.
