[0032] An installation cavity 8 is provided inside the boom arm 7. A through groove communicating with the installation cavity 8 is provided at the bottom end of the boom arm 7. An electric heating tube 9 and several miniature fans 10 are installed in the installation cavity 8. The electric heating tube 9 is directly above the through groove. The several miniature fans 10 are all directly above the electric heating tube 9, and their fan blades all face the electric heating tube 9. The electric heating tube 9 and the several miniature fans 10 are electrically connected to form a parallel circuit. A mesh metal plate 11 is installed in the through groove. A transition rod 12 is fixed to one end of the boom arm 7 near the splicing block 6. A connecting rod 13 is integrally formed on the end of the transition rod 12 away from the boom arm 7. First installation grooves 14 are provided on the upper and lower outer side walls of the connecting rod 13. A first conductive plate 15 is fixed in each of the two first installation grooves 14. Both first conductive plates 15 are electrically connected to the parallel circuit. The transition rod 12 and the connecting rod 13 have a first splicing groove 16 and a second splicing groove 17 respectively on opposite sides. The first splicing groove 16 and the second splicing groove 17 are spliced ​​to form a complete cavity. Two sliding rods 18 are slidably connected inside the cavity. One end of each sliding rod 18 extends into the second splicing groove 17, and a plug rod 19 is fixed to the opposite side of each sliding rod 18. The end of the plug rod 19 opposite to the sliding rod 18 extends out of the connecting rod 13 in a slidable connection manner. The other end of each sliding rod 18 extends into the first splicing groove 16, and a pressing rod 20 is fixed to each of them. The two pressing rods 20 are symmetrically arranged and a compression spring 21 is fixedly connected between them. The opposite ends of each pressing rod 20 extend out of the transition rod 12 in a slidable connection manner and a pressing plate 22 is fixed to each of them.

[0033] A mating block 23 is fixed to the side of the splicing block 6 near the mounting block 1. The mating block 23 is slidably inserted into the mating groove 3 and fixed by fastening bolts. A connecting sleeve 24 is fixed to the side of the splicing block 6 opposite to the mounting block 1. The connecting sleeve 24 allows the connecting rod 13 to be inserted in a mating connection manner. The inner walls of the upper and lower sides of the connecting sleeve 24 are provided with second mounting grooves 25 corresponding to the first mounting groove 14. A conductive substrate 26 and a second conductive plate 27 are installed in the second mounting groove 25. The conductive substrate 26 is fixed at the bottom of the second mounting groove 25. The second conductive plate 27 is slidably connected in the second mounting groove 25. A conductive spring 28 is fixedly connected between one end of the second conductive plate 27 and the conductive substrate 26. The other end of the second conductive plate 27 protrudes from the second mounting groove 25 and is set as an arc surface and fits against the first conductive plate 15. A mobile power supply 29 is installed inside the splicing block 6. The positive and negative poles of the mobile power supply 29 are electrically connected to the two conductive substrates 26, respectively. A complete circuit is formed between the power bank 29, the heating element 9, and several miniature fans 10. A switch 30 for controlling the circuit between the power bank 29, the heating element 9, and the miniature fans 10 is installed on the outer wall of the splicing block 6. Slots 31 are provided on the inner walls of both the left and right sides of the connecting sleeve 24, allowing the end of the insertion rod 19 facing away from the slide rod 18 to be inserted in a mating connection manner.

[0034] A positioning groove 32 is provided on the end of the connecting sleeve 24 that is away from the splicing block 6. A positioning block 33 for inserting into the positioning groove 32 is fixed on the transition rod 12.

[0035] Working principle:

[0036] When you need to store the hanger body, simply unscrew the threaded rod 5 from the threaded hole 4 to remove the hook 2.

[0037] By unscrewing the fastening bolts and pulling the mating block 23 out of the mating groove 3, the splicing block 6 can be removed from the mounting block 1, thereby separating the splicing assembly from the intermediate assembly.

[0038] Pressing the two pressing rods 20 by pressing the end of the transition rod 12 through the pressing plate 22 causes both pressing rods 20 to move into the cavity, thereby driving the two sliding rods 18 to move towards each other along the cavity. The sliding rods 18 drive the insertion rod 19 into the cavity, thereby causing the end of the insertion rod 19 that was originally inserted into the slot 31 to be pulled out of the slot 31. At the same time, the compression spring 21 is pressed to generate a rebound force. After the end of the insertion rod 19 that was originally inserted into the slot 31 is pulled out of the slot 31, the connecting rod 13 can be pulled out from the connecting sleeve 24, and the frame arm 7 can be removed from the splicing block 6. This allows the hanger body to be disassembled for easy storage and carrying.

[0039] Similarly, when the hanger body is needed, insert the threaded rod 5 into the threaded hole 4 to complete the installation of the hook 2.

[0040] Insert the mating block 23 into the mating groove 3 and tighten the fastening bolts to install the splicing block 6 onto the mounting block 1.

[0041] Press the pressing rod 20, align the positioning block 33 with the positioning groove 32, and then insert the connecting rod 13 into the connecting sleeve 24. As the connecting rod 13 continues to penetrate deeper into the connecting sleeve 24, it presses against the arc-shaped surface. The force acting on the arc-shaped surface can be decomposed into a force acting towards the second mounting groove 25. Under the action of this force, the second conductive plate 27 moves into the second mounting groove 25, and the conductive spring 28 is compressed, forming a rebound force towards the outside of the second mounting groove 25. When the connecting rod 13 is fully inserted into the connecting sleeve 24, the positioning block 33 is inserted into the positioning groove 32, the first mounting groove 14 and the second mounting groove 25 correspond, and the second conductive plate 27, under the action of the rebound force of the conductive spring 28, is tightly attached to the first conductive plate 15, ensuring that the first conductive plate 15 and the second conductive plate 27 can fully fit together and avoid poor contact. The positions of the insertion rod 19 and the slot 31 also correspond to each other. The positioning block 33 and the positioning groove 32 enable the connecting rod 13 to be quickly positioned. Then, the pressing lever 20 is released. Under the rebound force of the compression spring 21, the end of the insert rod 19 facing away from the slide rod 18 can slide out of the connecting rod 13 and be inserted into the slot 31 in a mating connection manner, thereby installing the arm rod 7 on the splicing block 6. The parallel circuit formed by the heating tube 9 and several micro fans 10 in the arm rod 7 is electrically connected to the switch 30 and the mobile power supply 29 through two first conductive plates 15 and two second conductive plates 27.

[0042] Clothes are hung on the hanger arm 7, and the hanger itself is suspended from a clothesline in the external environment via hooks 2. Then, pressing switch 30 connects the circuit between the power source 29, the heating element 9, and several miniature fans 10. The heating element 9 generates heat, and the miniature fans 10 generate airflow. The airflow blows towards the heating element 9, and the heat generated by the heating element 9 is discharged from the hanger arm 7 through the mesh metal plate 11, thereby drying the clothes hanging on the hanger arm 7.

[0043] This utility model can be quickly and easily assembled and disassembled, is easy to carry, and the clothes hanger itself has a drying function, which can dry clothes in time.

All standard parts used in this invention can be purchased commercially, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are already mature technologies.
