It should be noted that the heating temperature control of the heating wire 4 is existing technology, and the specific control components and control principles involved will not be described in detail here.

[0026] In this embodiment of the utility model, specifically, the noise reduction shell 2 includes a shell base material 21 disposed on the hair dryer body 1, and a sound insulation layer 22 is fixedly installed on the shell base material 21;

[0027] In order to achieve the effect of sound insulation and noise reduction, when the hair dryer body 1 is in use, the outer shell base material 21 and the sound insulation layer 22 can play the role of sound insulation and noise reduction for the hair dryer body 1, reducing the noise generated when the hair dryer body 1 is in use.

[0028] In this embodiment of the utility model, specifically, the magnetic adsorption mechanism 8 includes a groove 81 disposed on the noise reduction housing 2, a magnet ring 82 fixedly sleeved on the inner wall of the groove 81, and an iron ring 83 fixedly installed on the inner wall of the filter box 6, with the iron ring 83 sleeved on the magnet ring 82.

[0029] To facilitate the disassembly and assembly of filter box 6, simply pull filter box 6 outwards. Under strong force, iron ring 83 will separate from magnetic ring 82, thus completing the disassembly of filter box 6. Simply put filter box 6 onto the tank 81. Under the action of magnetic attraction, magnetic ring 82 and iron ring 83 will stick together to complete the installation of filter box 6. The operation is quite convenient.

[0030] In this embodiment of the utility model, specifically, the filter screen disassembly and assembly mechanism 12 includes a sleeve 121 fixedly installed on the disassembly and assembly ring 10.

An indicator block 1210 is fixedly installed on the pressure block 124. An indicator mark 1211 is opened on the upper surface of the mounting ring 9. The indicator block 1210 and the indicator mark 1211 correspond to each other.

[0031] To facilitate the removal and cleaning of the filter screen 11 from the filter box 6, press down on the pressing block 124 and allow the locking block 128 to enter the locking groove 127. Then rotate the insert rod 123 and rotate the locking block 128 to correspond with the through groove 125. Pull the insert rod 123 directly upward from the slot 122. At this point, the filter screen 11 can be removed directly for cleaning. When it is necessary to install the filter screen 11 into the filter box 6, insert the insert rod 123 into the slot 122 and allow the locking block 128 to enter the through groove 127. Corresponding to the position of the through groove 125, the locking block 128 will enter the annular groove 126 through the through groove 125. Then rotate the pressure block 124 and make the indicator block 1210 correspond to the indicator mark 1211. Release the pressure block 124. At this time, under the action of the compression spring 129, the locking block 128 can be driven to engage in the locking groove 127.

[0033] By setting up the positioning groove 1212 and the positioning block 1213, the positioning block 1213 can be engaged in the positioning groove 1212 to position the sleeve 121.

[0034] Working principle: During use, the noise-reducing outer shell 2 is located behind the heat-insulating outer shell 3. The heating wire 4 inside the heat-insulating outer shell 3 is responsible for the heating function inside the hair dryer body 1. The outer shell base material 21 and the sound insulation layer 22 reduce noise in the hair dryer body 1 without affecting its heat dissipation. On the other hand, the filter screen 11 can filter dust during use, reducing the entry of dust. After long-term use, in order to disassemble and clean the filter box 6 and filter screen 11, simply pull the filter box 6 outward. Under strong force, the iron ring 83 will separate from the magnetic ring 82, thus completing the disassembly of the filter box 6. Then press down on the pressing block 124 and let the locking block 128 enter the locking slot 127. Then rotate the insertion rod 123 and rotate the locking block 128 to correspond to the through slot 125. Then push the insertion rod 123 upward from the slot 1. Pull out from 22. Then, you can directly remove and clean the filter screen 11. When you need to install the filter screen 11 in the filter box 6, insert the rod 123 into the slot 122 and align the position of the locking block 128 with the through groove 125. The locking block 128 will enter the annular groove 126 through the through groove 125. Then rotate the pressure block 124 and align the indicator block 1210 with the indicator mark 1211. Release the pressure block 124. At this time, under the action of the compression spring 129, the locking block 128 can be driven to engage in the slot 127. The rod 123 will also rest on the hoop 121 to prevent the filter screen 11 from falling off. At this time, the filter screen 11 can be installed in the filter box 6. Simply put the filter box 6 on the groove 81. Under the action of magnetic attraction, the magnetic ring 82 and the iron ring 83 will stick together to complete the installation of the filter box 6. The operation is relatively convenient.
