DETAILED DESCRIPTION

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] like Figure 1-4 The example shown is an embodiment provided by the utility model.

[0031] The embodiment of the utility model provides a hair dryer, including: an outer shell 10, a mounting base 20 and a back cover 30, the outer shell 10 is cylindrical, the main parts of the mounting base 20 and the back cover 30 are both circular, and the outer diameters of the mounting base 20 and the back cover 30 are both adapted to the inner diameter of the outer shell 10, the mounting base 20 and the back cover 30 can both be just fitted into the outer shell 10, specifically, the mounting base 20 is installed in the outer shell 10 and close to its front end, and the back cover 30 is installed at the rear end of the outer shell 10. It should be noted that the front end of the outer shell 10 is the air outlet end of the hair dryer, and the rear end is the end opposite to the air outlet end. Among them, a first limiting groove 21 is provided on the outer side wall of the mounting seat 20, and a first limiting block 11 is provided on the inner side wall of the shell 10 near its front end. The mounting seat 20 is put in from the rear end of the shell 10, and the first limiting groove 21 is engaged with the first limiting block 11, so that the mounting seat 20 can be detachably fixed in a position near the front end of the shell 10, so that the mounting seat 20 will not move forward or backward or rotate in the shell 10; a second limiting groove 31 is provided on the outer side wall of the rear cover 30, and a second limiting block 12 is provided on the inner side wall of the shell 10 near its rear end. The back cover 30 is put in from the rear end of the shell 10, and the second limiting groove 31 abuts against the second limiting block 12, so that the back cover 30 can no longer move toward the front end or rotate circumferentially, and can only be moved backward and taken out; a first connecting tube 22 is provided at the inner end of the mounting seat 20, and a second connecting tube 32 is provided at the inner end of the back cover 30. The first connecting tube 22 and the second limiting tube 32 are connected. The two connecting tubes 32 are detachably connected. When the first connecting tube 22 is connected and fixed with the second connecting tube 32, the back cover 30 is also fixed. The back cover 30 cannot move backward and fall out of the outer shell 10. At this time, the back cover 30 and the mounting base 20 are both fixed in the outer shell 10, so the hair dryer parts arranged in the outer shell 10 are also fixed in the cavity enclosed by the mounting base 20, the back cover 30 and the outer shell 10; when the connection between the first connecting tube 22 and the second connecting tube 32 is disconnected, not only can the back cover 30 be taken out from the rear end of the outer shell 10 and then the parts in the outer shell 10 can be installed and repaired, but also the connection between the mounting base 20 and the outer shell 10 can be disassembled from the front end of the outer shell 10, and then the mounting base 20, the internal parts of the hair dryer and the back cover 30 can be pushed out of the outer shell 10 as a whole from the front to the back. The disassembly is more efficient and it is also more convenient for the subsequent repair or maintenance of the hair dryer.

[0032] Furthermore, the first limit groove 21 is in an "L" shape, and the first limit block 11 is in an inverted "L" shape. When placing the mounting base 20 into the outer shell 10, it is necessary to first align the position of the first limit block 11 with the first limit groove 21, and then rotate the mounting base 20 to make the first limit block 11 and the first limit groove 21 engage and fix. Through this engaging structure fixation, subsequent disassembly is also easier.

[0033] Furthermore, the inner end of the first connecting tube 22 and the inner end edge of the second connecting tube 32 both have a certain thickness, the inner end of the first connecting tube 22 is provided with a plurality of positioning grooves 221, the inner end of the second connecting tube 32 is provided with a plurality of positioning blocks 321, the positioning grooves 221 are connected with the positioning blocks 321 in a one-to-one correspondence, the positioning grooves 221 are inserted into the positioning blocks 321, so that the first connecting tube 22 and the second connecting tube 32 will not rotate relative to each other. The inner end of the first connecting tube 22 is provided with a plurality of connecting holes 222, the inner end of the second connecting tube 32 is provided with a plurality of threaded holes 322, through the connection and positioning of the positioning grooves 221 and the positioning blocks 321, the position of the connecting hole 222 can correspond to the position of the threaded hole 322 in a one-to-one correspondence, the connecting hole 222 and the threaded hole 322 are connected in a one-to-one correspondence through screws, the connection is more firm, and it is also very simple to disassemble. In addition, a decorative tube 23 is sleeved inside the first connecting tube 22, and the outer end of the decorative tube 23 is clamped with the outer end of the first connecting tube 22 to cover the screws. The inner diameter of the inner end of the decorative tube 23 is the same as the inner diameter of the inner end of the second connecting tube 32, making the hair dryer more neat and beautiful in appearance.

[0034] Specifically, a heating wire group 40 is arranged between the first connecting tube 22 and the housing 10, and a circuit main board 50 is arranged between the second connecting tube 32 and the housing 10, and the circuit main board 50 is electrically connected to the heating wire group 40. A hollow handle 60 is connected to the side wall of the housing 10, and a fan assembly (not shown in the drawings) is arranged in the handle 60, and the fan assembly is electrically connected to the circuit main board 50. A plurality of air outlets 24 are arranged at the connection between the mounting seat 20 and the first connecting tube 22, and the air outlets 24 are connected to the handle 60.
