Description

Technical Field

[0001] The utility model belongs to the technical field of hair straighteners, in particular to an air inlet filtering structure of a hair straightener. Background Art

[0002] A hair straightener is a commonly used device for straightening and straightening hair. Existing hair straighteners generally include two rotatably connected hairpins, with a heating body provided on opposite sides of the hairpins. When in use, the hair is clamped between the two hairpins and the heat emitted by the heating body drags the hair to achieve straightening or straightening of the hair. However, the temperature of the heating body of the existing hairpins is often high, which can easily damage the hair during use, causing problems such as dry, yellow and dehydrated hair. To solve this problem, people have developed a hair straightener with a cold air blowing function, the purpose of which is to quickly cool the hair after it is heated, and reduce the damage to the hair caused by the excessive temperature of the heating body. However, hair heated at high temperatures will inevitably cause a certain degree of damage, and the use effect is not ideal. Furthermore, people have developed hair straighteners that heat the hair by blowing out hot air and then straighten it. These hair straighteners include a handle and a hairpin plate hinged on the handle. The handle is provided with a main circuit board, a motor and a heating element. The hairpin plate has an air outlet connected to the air outlet end of the handle. The motor drives the fan blades to rotate and the heating element generates heat to blow out hot air to heat and straighten the hair clamped by the hairpin plate. In order to prevent dust from entering the hair straightener, a filter and an air inlet cover are generally provided at the air inlet, but the air inlet cover is generally fixed, which makes it inconvenient to clean the filter, and after long-term use, the air intake efficiency is reduced. Of course, there are also detachable air inlet covers, but the overall filtering structure still has the problems of inconvenient disassembly and assembly, complex structure or unstable structure.
