Technical Field
[0001] The utility model relates to the technical field of hair dryers, and particularly relates to a hair dryer without a wind guiding bracket. Background Art
[0002] Common hair dryers (i.e., hair driers) usually are provided with a wind guiding bracket for changing the flow direction of the air flow in the hair dryer body to realize normal air blowing. Due to the presence of the wind guiding bracket, the further miniaturization of the structure of the hair dryer is restricted. In view of the above technical problems, the utility model proposes a new technical solution, which does not require the setting of a wind guiding bracket and uses the heating wire bracket to play a role in guiding the wind, so that the structure of the hair dryer is more compact and miniaturized.
[0003] It can be seen that the prior art still needs to be improved and enhanced. Content of the Utility Model
[0004] In view of the deficiencies of the above prior art, the purpose of the utility model is to provide a hair dryer without a wind guiding bracket, aiming to solve the technical problem that a wind guiding bracket must be provided in the prior art for hair dryers.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A hair dryer without a wind guiding bracket includes a handle part and a main body part. The main body part includes a housing and a heating module. An end cover is provided at the air inlet end of the housing, and a wind guiding cover is provided at the air outlet end of the housing; the heating module includes a heating wire bracket and a heating wire; a PCB board is provided at the air inlet end of the heating wire bracket, and a wind channel is formed by the PCB board, the heating module and the housing.

[0021] The present utility model provides a hair dryer without a wind guiding bracket. To make the purpose, technical solution, and effects of the present utility model clearer and more definite, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0022] Please refer to Figures 1 to 6 , the present utility model provides a hair dryer without a wind guiding bracket. The drawings are only used to explain the structural principle and are not in proportion to the actual product. The drawings only show the structures related to the inventive points of the present application, and some conventional structures are not specifically shown. Figure 4 The arrows in
[0023] The terms "first", "second", etc. described in this text are merely used to name similar structures differently for the convenience of description, and do not limit this application. For the convenience of description, some orientation terms are inevitably used in this text, but these orientation terms do not limit this application because they can be set in different directions in actual applications. The "multiple" described in this text refers to an indefinite quantity because the number of the structures referred to is not the inventive point, so no specific limitation is made. The "air inlet end" and "air outlet end" described in this text are a pair of relative concepts and are named according to the air flow direction during normal use (i.e., the air inlet end is located upstream of the air outlet end).
[0024] The hair dryer without a wind guiding bracket includes a handle part A and a main body part B. The main body part includes a housing 1 and a heating module. An end cap 2 is provided at the air inlet end of the housing, and a wind guiding cover 7 is provided at the air outlet end of the housing. A plurality of air inlets (not shown in the figure) are provided on the end cap; the heating module includes a heating wire bracket and a heating wire 6; a PCB board 4 is provided at the air inlet end of the heating wire bracket, and a wind channel is formed by the PCB board, the heating wire bracket and the housing.
[0025] In actual application, a power switch 91 and a gear shifting key 92 are usually provided on the handle part, and the power switch, the gear shifting key and the heating wire described above are respectively connected to the PCB board.
[0026] As Figure 5 shown, further, the heating wire bracket includes a cylinder body 51 and a plurality of support pieces 52 provided on the cylinder body; the heating wire is wound around the support pieces; the cylinder body is provided with a first slot 510 equal in number to the support pieces in the circumferential direction, and each support piece is respectively inserted into the corresponding first slot.
[0027] As Figure 3 shown, further, each support piece is respectively provided with a plurality of mounting grooves 520 for mounting the heating wire.
[0028] Further, in the projection on the plane perpendicular to the axis of the cylinder body (i.e., the perspective of the side view), the projection of the cylinder body falls within the projection of the PCB board. This setting makes the area of the PCB board large enough, that is, it is convenient to cover the air inlet end of the cylinder body, that is: the air inlet end of the cylinder body abuts against the PCB, so that during actual use, the air flow can smoothly contact the heating wire after bypassing the edge of the PCB board, rather than entering the interior of the cylinder body.
[0029] Further, a display screen 3 is provided on the end cap, and the display screen is connected to the PCB board. The display screen is used to display information such as the temperature of the air heated by the heating wire.
[0030] As Figure 5 and Figure 6As shown in the figure, further, a second groove 701 is provided on the inner side of the air guide cover, and the air outlet end of the cylinder body is inserted into the second groove. This setting facilitates the connection between the cylinder body and the air guide cover, and the air flow will not flow back into the interior of the cylinder body from the air outlet end of the cylinder body after passing through the heating wire.
[0031] A contraction section is provided at the air inlet end of the air guide cover, and the air outlet ends of the respective support sheets are respectively abutted against the inner wall of the contraction section. This setting makes the installation of the support sheets more firm.
[0032] A plurality of air outlet openings 702 are provided on the air guide cover, and each air outlet opening communicates with the inner cavity of the contraction section. This setting enables the air flow in the body to be smoothly ejected from the air guide cover after passing through the heating wire.
[0033] During actual use, the air flow enters from the end cover, passes through the space between the PCB board and the housing (i.e., the air bypasses the outer edge of the PCB board), then passes through the space between the heating module and the housing (is heated when passing through the heating wire), and then is ejected through the air guide cover. It can be seen that, compared with the prior art, the technical solution provided by the present utility model does not require a dedicated air guide bracket, and the air duct formed between the PCB board, the heating module and the housing, as well as the air guide cover can play the role of guiding air.
[0034] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution of the present utility model and its inventive concept, and all such changes or substitutions should fall within the protection scope of the present utility model.
