[0023] See also Figures 1 to 3 The utility model provides a hair dryer with an easily disassembled filter screen, comprising a body 8 and a filter screen assembly.

[0024] The main body 8 is composed of an outer shell, a fan located inside the outer shell, parts such as a resistance wire, and a handle connected to the outer shell. The main body 8 has an air inlet end and an air outlet end relative to each other. The air inlet end of the main body 8 is concave toward the air outlet end to form a concave portion, and the concave portion extends along the axial direction of the main body 8.

[0025] The recessed portion includes a bottom wall 2 and a side wall 1 that forms a columnar cavity. The length of the side wall 1 can be set between 5-12 cm. The two ends of the side wall 1 respectively have a first opening and a second opening that are connected to the columnar cavity, wherein the first opening is close to the air outlet end of the main body 8, and the bottom wall 2 is fixed at the first opening. The bottom wall 2 and the side wall 1 can be an integral structure, and the bottom wall 2 has a third opening that is connected to the columnar cavity. Specifically, the third opening is circular.

[0026] The filter assembly includes a connecting tube 3, a first filter 4, a second filter 5 and a handle 6, wherein the connecting tube 3 can be embedded in the third opening, the first filter 4 is fixed in the connecting tube 3, and the plane where the first filter 4 is located is perpendicular to the axial direction of the main body 8, the second filter 5 is embedded in the second opening, and the mesh inner diameter of the second filter 5 is larger than the mesh inner diameter of the first filter 4. Specifically, the aperture of the first filter 4 can be set between 0.1-0.2mm, and the aperture of the second filter 5 can be set between 0.2-0.4mm. By setting two filters, the filtering effect of the filter assembly of the hair dryer can be improved to prevent foreign objects such as broken hair from entering the hair dryer, thereby protecting the parts inside the hair dryer from damage.

[0027] The handle 6 is fixed on the surface of the first filter screen 4 near the second filter screen 5. When disassembling the filter assembly, it is only necessary to remove the second filter screen 5 from the second opening of the side wall 1, and then remove the connecting tube 3 through the handle 6, thereby facilitating the disassembly of the first filter screen 4 and the second filter screen 5, and thus facilitating the cleaning of the filter screen.

[0028] Specifically, the handle 6 is a U-shaped structural member, and the two ends of the handle 6 are fixedly connected to the first filter 4, so that it is convenient for fingers to be embedded in the handle 6 and to facilitate taking the connecting tube 3 out of the recessed portion.

[0029] Optionally, in order to make the connection between the connecting tube 3 and the third opening more stable and to facilitate the installation of the connecting tube 3, the third opening of the bottom wall 2 is connected to a sleeve 7, which extends along the axial direction of the main body 8. The connecting tube 3 is embedded in the sleeve 7, and the inner diameter of the sleeve 7 is equal to the outer diameter of the connecting tube 3, so that the connecting tube 3 can be embedded in the sleeve 7.

[0030] Furthermore, sleeve 7 protrudes from bottom wall 2 and extends toward second filter screen 5. When connecting sleeve 3 and sleeve 7 are connected, the end of connecting sleeve 3 is flush with the plane of bottom wall 2, thereby increasing the contact area between sleeve 7 and connecting sleeve 3 and ensuring a stable connection between the two. Specifically, the length of sleeve 7 is set between 8 and 15 mm, for example, the length of sleeve 7 can be 10 mm.

[0031] Optionally, the side wall 1 includes multiple wall surfaces, which are respectively a first wall surface, a second wall surface, and a third wall surface distributed from the inside to the outside and connected in sequence. The inner diameters of the first wall surface, the second wall surface, and the third wall surface increase in sequence. A first step surface 9 is formed between the first wall surface and the second wall surface, and a second step surface 10 is formed between the second wall surface and the third wall surface. An annular flange 11 is formed on the end of the connecting tube 3 away from the sleeve 7. The annular flange 11 abuts against the first step surface 9. The annular flange 11 is mainly used to limit the connecting tube 3 to prevent the connecting tube 3 from completely entering the recessed portion. At the same time, the first step surface 9 can also ensure a stable connection between the connecting tube 3 and the side wall 1.

[0032] In addition, the outer diameter of the second filter screen 5 is equal to the inner diameter of the third wall surface, and the second filter screen 5 abuts against the second step surface 10, and the second step surface 10 can limit the second filter screen 5. At the same time, the second filter screen 5 can also be clamped between the third wall surface and the second step surface 10 to make it more stable.

[0033] Specifically, the length of the third wall is at least twice the thickness of the second filter screen 5 , so that the second filter screen 5 can be completely embedded in the third wall, thereby improving its stability.

[0034] Optionally, in order to facilitate the removal of the second filter 5 from the side wall 1, a slot 12 is provided on the side edge of the second filter 5, and the inner diameter of the slot 12 is set at 3-5 mm. When removing the second filter 5, a sharp object can be embedded in the slot 12 and the second filter 5 can be pulled outward to remove the second filter 5.

[0035] The above are only preferred implementation methods of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
