[0002] At present, the hair dryers commonly seen on the market are mostly used for drying and assisting hair styling. Due to the diversity of styling and high frequency of use, dust or hair is easily accumulated on the tail cover. Most hair dryers on the market have a non-detachable tail cover, which will cause hair dust to accumulate and cannot be cleaned, affecting the service life of the hair dryer and further affecting the health of the user. Some hair dryers also use a detachable tail cover structure, which is usually tightly fitted or buckled in. This connection method is easily affected by thermal expansion and contraction during use, and may become loose or too tight to be removed, thereby affecting the normal use of consumers.

[0019] The hair dryer with a magnetically connected tail cover of the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0020] Please also see Figures 1 to 7 A hair dryer with a magnetically connected tail cover comprises a hair dryer body 10, a front end surface of which is formed with an air outlet 11 that passes through the interior thereof, and a tail cover 30 that can be detachably connected to the tail end thereof.

[0021] Preferably, a circular plate-shaped fixed bracket 30 is provided inside the hair dryer body 10 and near its tail end; a first magnet 31 is embedded on the side wall of the fixed bracket 30 facing the air outlet 11 of the hair dryer body 10, and a second magnet 21 corresponding to the first magnet 31 is embedded on the inner side wall of the tail cover 50 facing the tail end of the hair dryer body 10. The mutual magnetic attraction between the first magnet 31 and the second magnet 21 allows the tail cover 50 to be encapsulated and set on the end of the second connecting end 19.

[0022] The structures of the first magnet 31 and the second magnet 21 can be selected from any one of the following: a circular magnet, a plurality of arc-shaped magnets connected end to end or spliced ​​at intervals in sequence to form a circular magnet, a plurality of coaxially arranged multi-layer circular magnets with progressively offset diameters, and a multi-layer circular magnet formed by coaxially arranging circular magnets and spliced ​​circular magnets; the first magnet 31 and the second magnet 21 are arranged on the same central axis and can overlap with each other.

[0023] A first magnet groove 33 which is coaxial with the air outlet 11 is formed on the side wall of the fixed bracket 30 facing the air outlet 11 of the hair dryer body 10. The first magnet 31 is embedded in the first magnet groove 33. A magnetic conductive wall 35 is formed between the bottom of the first magnet groove 33 and the other side wall of the fixed bracket 30.

[0024] After repeated and careful experiments, it is concluded that the thickness of the magnetic conductive wall 15 is 1.0-1.5 mm. The magnetic conductive wall 15 of this thickness can not only play a role of isolation, but also ensure that it will not block the magnetism of the magnet.

[0025] A second magnet groove 23 is formed on the inner side wall of the tail cover 50 facing the tail end of the hair dryer body 10 and is arranged coaxially with the air outlet 11. The second magnet 21 is embedded in the second magnet groove 23; the first magnet 31 and the second magnet 21 are magnetically attracted to each other and are respectively adsorbed on the inner and outer sides of the magnetic conductive wall 35.

[0026] An annular positioning groove 32 which is coaxial with the first magnet groove 33 is formed on the outer wall of the fixed bracket 30 at one end facing the tail cover 20, and a positioning convex ring 24 corresponding to the positioning groove 32 is formed on the side wall of the tail cover 20 located on the second magnet 21. The positioning convex ring 24 can be plugged into the positioning groove 32 in a concave-convex manner and can rotate relatively.

[0027] A plurality of mounting holes 34 are evenly distributed on the fixed bracket 30 and located outside the positioning groove 32, and a plurality of connecting blocks 17 corresponding to the mounting holes 34 are formed on the inner wall of the hair dryer body 10 and near its rear end. The fixed bracket 30 can be connected and fixed to the rear end of the hair dryer body 10 by passing fasteners through the mounting holes 34 and the connecting blocks 17 in sequence.

[0028] During actual use, the first magnet 31 is fixed in the hair dryer body 10 and is blocked by the fixed bracket 30. However, at the same time, since the first magnet 31 is embedded in the first magnet slot 33, and the wall thickness of the magnetic conductive wall 15 can not only just isolate the first magnet 31, but also prevent external impurities from entering and affecting it, and can also ensure that its magnetism is not blocked. The tail cover 20 embedded with the second magnet 21 is closed toward the rear end of the hair dryer body 10, and the first magnet 31 and the second magnet 21 are automatically magnetically attracted, thereby fixing the tail cover 20 on the rear end of the blower body 10.

[0029] In summary, the hair dryer with a magnetically connected tail cover of the present invention is provided with a fixed bracket in the inner cavity of the tail end of the hair dryer body, and a first magnet is embedded on the side wall of the fixed bracket facing the inner cavity of the hair dryer body, the first magnet can be against the magnetic conductive wall, and at the same time, a second magnet corresponding to the first magnet is embedded on the side of the tail cover facing the fixed bracket, and the first magnet and the second magnet are magnetically attracted to each other to fix the tail cover on the tail end of the hair dryer body. The hair dryer with a magnetically connected tail cover of the present invention effectively solves the problem that the tail cover becomes loose or too tight to be disassembled due to thermal expansion and contraction during use of the hair dryer, and at the same time, the positioning convex ring on the tail cover and the positioning groove on the fixed bracket are connected with each other in a concave-convex manner, which effectively ensures the precise positioning of the first magnet and the second magnet, and the case innovatively sets the magnet inside the hair dryer body, which can not only ensure the consistency of the appearance, but also effectively prevent the oxidation and rusting of the magnet, with a novel structure and ingenious design, which improves market competitiveness.
