DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 In this embodiment, a hair dryer with a ceramic heating element with a built-in terahertz coating includes a handle 1, a rotating rod 2 is fixed inside the handle 1, and hinge blocks 3 are rotatably connected to the front and rear sides of the rotating rod 2. The handle 1 can be flipped by the arranged rotating rod 2, so that the whole is easy to store. An air guide tube 4 is fixed on the top of the hinge block 3, and a traction component 5 is fixed inside the air guide tube 4. The arranged traction component 5 is a driving motor and a fan, which is the existing technology of the hair dryer, and the operating principle will not be described in detail here.

[0024] In addition, a ceramic heating element 6 is fixed inside the air duct 4. The ceramic heating element 6 has the advantages of corrosion resistance, high temperature resistance, long service life, high efficiency and energy saving, uniform temperature, good thermal conductivity and fast thermal compensation speed, which makes the whole more practical. The outer surface of the ceramic heating element 6 is coated with a terahertz coating. Through the setting of the terahertz coating, the minimum coating thickness can be guaranteed to avoid excessive use of materials and waste of resources. An air outlet 7 is fixed on the left side of the air duct 4.

[0025] Furthermore, a buffer component 8 is provided inside the handle 1 and extends to the outside of the handle 1. The buffer component 8 is used to buffer the pulling force. A circuit board 10 is fixed inside the handle 1. A button 11 is fixed on the left side of the handle 1. A filter screen 12 is fixed inside the air guide tube 4. A positioning component is provided on the right side of the air guide tube 4. The positioning component is used to fix the filter screen 12. The positioning component includes an abutment block 13, a positioning rod 14, a positioning block 15 and an abutment plate 16. The abutment block 13 is fixed to the positioning rod 14. The positioning rod 14 is slidably connected to the air guide tube 4. The outer surface of the positioning rod 14 is slidably connected to the positioning block of the air guide tube 4. 15 is fixed, the left side of the abutment block 13 is fixed to the abutment plate 16, a positioning groove matched with the positioning rod 14 is provided inside the air guide tube 4, a through groove connected with the positioning groove is provided inside the air guide tube 4, the through groove is slidably connected with the positioning block 15, and the positioning block 15 can slide to the inside of the air guide tube 4 through the set through groove, and a limiting groove connected with the through groove is provided inside the air guide tube 4, and the limiting groove and the positioning groove are both arc grooves, and the positioning block 15 can slide from the through groove to the inside of the limiting groove through the set limiting groove, a friction strip is fixed on the outer surface of the abutment block 13, and an extrusion pad is fixed on the left side of the abutment plate 16.

[0026] In general, the positioning groove and the through groove are set so that the positioning rod 14 and the positioning block 15 can slide together into the interior of the air guide tube 4, and the limiting groove and the positioning groove are both arc grooves, so that the positioning rod 14 can slide inside the positioning groove, and the positioning block 15 will slide from the through groove to the inside of the limiting groove, so that the air guide tube 4 limits the left and right movement of the positioning block 15 through the limiting groove, and when the abutment plate 16 squeezes and fixes the filter screen 12, the extrusion pad will produce a certain deformation, thereby increasing the friction between the positioning block 15 and the limiting groove, effectively improving the overall practicality.

[0027] See also Figure 3-4 In order to buffer the pulling force, the buffer component 8 in this embodiment includes a support rod 801 fixed to the handle 1, and a sliding block 802 is slidably connected to the outer surface of the support rod 801, and a stabilizing block is fixed on the left and right sides of the sliding block 802. A stabilizing groove slidably connected to the stabilizing block is provided inside the handle 1. The stabilizing block and the stabilizing groove can effectively improve the stability of the movement of the sliding block 802, and a limiting plate 803 is fixed on the outer surface of the support rod 801. The limiting plate 803 can effectively limit the position of the sliding block 802. A buffer spring 804 is fixed between the sliding block 802 and the handle 1, and the buffer spring 804 is a rigid spring. A protective cover 805 that penetrates the outside of the handle 1 is fixed to the bottom of the sliding block 802, and a sponge pad 9 is covered on the outer surface of the handle 1. The protective cover 805 is a PVC soft rubber cover, and a power cord 806 is fixed inside the protective cover 805.

[0028] In general, when the power cord 806 is subjected to a pulling force, the sliding block 802 will be pulled to move, so that the buffer spring 804 will produce elastic deformation, effectively buffering the pulling force, so that the power cord 806 can be more stable, and the overall practicality is effectively improved.

[0029] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0030] The working principle of the above embodiment is:

[0031] When the power cord 806 is connected to the socket, the button 11 can be pressed to enable the circuit board 10 to control the traction component 5 to start, thereby generating wind force to dry hair and other items. When the handle 1 is accidentally moved to pull the power cord 806, the protective cover 805 and the sliding block 802 will move downward along the support rod 801, thereby squeezing the buffer spring 804, causing the buffer spring 804 to produce elastic deformation, thereby buffering the pulling force, thereby effectively ensuring the stability of the power cord 806 and making it difficult for the power cord 806 to separate from the socket. The overall structure is simple, which effectively improves the overall practicality.
