Description

Technical Field

[0001] This utility model relates to a duct connector, specifically a magnetic duct connector, and belongs to the field of duct connectors. Background Technology

[0002] Duct connectors are used to connect the exhaust port of a fan to an external exhaust duct, allowing the air exhausted by the fan to circulate to the outside through the duct. Existing duct connectors typically use straps or loops to secure the connection at both ends and to the external exhaust duct during installation, ensuring a firm and leak-proof connection. However, this method of binding makes installation and disassembly inconvenient, causing difficulties in initial installation and subsequent replacement and maintenance. Often, professional operation is required to achieve the intended effect, presenting certain limitations. Utility Model Content

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figure 1-7 As shown, a magnetic duct connector includes a first connector 1 and a second connector 2. The first connector 1 and the second connector 2 are magnetically connected at one end by a magnetic mechanism, and the other ends of the first connector 1 and the second connector 2 are respectively connected to the air outlet of the fan and the exhaust pipe. The first connector 1 and the second connector 2 are both provided with a first flow hole 4 and a second flow hole 11 for gas flow.

[0028] As a technical optimization of this utility model, the first connector 1 is connected to the connection end of the fan with a second insert ring 8, the second insert ring 8 is integrally connected to the end of the first flow hole 4, and multiple fixing holes 3 are provided through the corner of the first connector 1.

[0029] As a technical optimization of this utility model, the end of the first connector 1 facing the second connector 2 is connected to a first insert ring 7, and the first insert ring 7 is integrally connected to the end of the first flow hole 4.

[0030] As a technical optimization of this utility model, a retaining ring 5 is connected to the inner wall of the first flow hole 4. The retaining ring 5 can limit the end of the insertion tube 12, making the insertion and installation more stable.

[0031] As a technical optimization of this utility model, the end of the second connector 2 facing the first connector 1 is connected to the insertion tube 12 and the sleeve 13. The end of the insertion tube 12 is integrally connected to the end of the second flow hole 11, and the end of the sleeve 13 is integrally connected to the end of the second connector 2. The insertion tube 12 is located inside the sleeve 13 and its length is greater than that of the sleeve 13.

[0032] As a technical optimization of this utility model, the outer diameter of the insertion tube 12 is adapted to the inner diameter of the first flow hole 4.

[0033] As a technical optimization of this utility model, a sealing groove 14 for the insertion and installation of the first insertion ring 7 is provided between the bottom outer wall of the insertion tube 12 and the bottom inner wall of the sleeve 13. When the first connector 1 and the second connector 2 are inserted, the end of the insertion tube 12 is inserted into the interior of the first insertion ring 7 until it abuts against the retaining ring 5, and at the same time, the first insertion ring 7 is inserted into the interior of the sealing groove 14.

[0034] As a technical optimization of this utility model, the other end of the second connector 2 is connected to a connecting pipe 9 for duct insertion, and the inner wall of the second flow hole 11 is provided with a threaded strip 10 for duct connection. The end of the exhaust pipe is threadedly connected to the second connector 2 via the threaded strip, which is simple and quick to install and eliminates the need for the operation of using an external collar for tightening.

[0035] As a technical optimization of this utility model, the magnetic mechanism includes two magnetic sealing strips 6. The end of the first insertion ring 7 away from the first connector 1 and the bottom end of the sealing groove 14 are both connected to the magnetic sealing strips 6, and the two magnetic sealing strips 6 can magnetically attract each other. This not only makes the insertion of the first connector 1 and the second connector 2 stable, but also improves the sealing performance at the connection.

[0036] When using this duct connector, insert the second insertion ring 8 at one end of the first connector 1 into the interior of the fan exhaust port. Then, use bolts to pass through the fixing hole 3 to install and fix the first connector 1 onto the fan. Next, insert one end of the exhaust pipe to be used into the interior of the connecting pipe 9, and rotate the second connector 2 accordingly. The end of the exhaust pipe is threadedly connected to the second connector 2 via a threaded strip. Installation is simple and quick, eliminating the need for external collar tightening. Because the exhaust pipe used is a flexible corrugated pipe, the texture of the corrugated pipe and the threaded strip 10 can form a threaded installation.

[0037] Finally, the second connector 2 is inserted into the outside of the first connector 1 and connected magnetically. Once connected, it is not easily dislodged, requiring no additional fixing devices. Installation and disassembly are simple and convenient, and subsequent maintenance and replacement are easy. When the first connector 1 and the second connector 2 are inserted, the end of the insertion tube 12 is inserted into the interior of the first insertion ring 7 until it abuts against the retaining ring 5. At the same time, the first insertion ring 7 is inserted into the interior of the sealing groove 14. The two magnetic sealing strips 6 attract each other, ensuring a stable connection between the first connector 1 and the second connector 2 and improving the sealing performance at the connection. After the first connector 1 and the second connector 2 are installed, the air discharged from the fan outlet enters the exhaust pipe through the first flow hole 4 and the second flow hole 11 and is then discharged outwards.

[0038] When it is necessary to disassemble the first connector 1 and the second connector 2, simply pull the second connector 2 outward to detach it from the first connector 1; it is simple and quick. No additional binding tools are required at the connection between the first connector 1 and the second connector 2, making it more efficient in use.
