Description

Technical Field

[0001] This utility model belongs to the field of hair dryer technology, and in particular relates to an electric motor mounting structure and a straightener / curler structure. Background Technology

[0002] A hair dryer is a common household appliance that uses electricity to generate hot airflow to accelerate the evaporation of moisture and achieve a drying effect. A hair dryer consists of a handle, air duct, motor, heating element, and air outlet.

[0003] For example, Chinese utility model patent document CN221012298U discloses a portable hair dryer, including an inner shell, an outer shell, and a handle. The inner shell houses a control circuit board, with a heating element and a driving element connected to its two ends respectively. One end of the inner shell is connected to a partition cylinder, and the heating element is placed inside the partition cylinder. The outer shell is fitted over the inner shell, with a nozzle detachably connected to one end. An air inlet slot is formed at the other end of the outer shell. A connecting portion extends from the outer side of the outer shell, with a first inclined surface at one end and a connecting seat extending from the first inclined surface. The handle has a second inclined surface at one end, with a connecting hole on the second inclined surface. The connecting hole is slidably connected to the connecting seat, and the first and second inclined surfaces are in slidable contact. The inner shell is composed of a left inner shell and a right inner shell combined. The control circuit board and driving element are located between the left and right inner shells. A display device is embedded in the left inner shell, with one end of the display device penetrating the left inner shell and connected to the control circuit board. One side of the control circuit board extends out of the inner shell. The drive assembly includes a bracket, a drive unit, and fan blades. The bracket is fixedly connected to the control circuit board, the drive unit is placed on the bracket, the drive unit is electrically connected to the control circuit board, and the fan blades are fixedly connected to the output shaft of the drive unit.

[0004] As can be seen, the aforementioned patent document utilizes the assembly of left and right inner shells to form an air duct, and clamps the drive mechanism within the inner shell. The assembly of the left and right inner shells typically involves screw locking, and before locking, the drive mechanism needs to be fixed to either the left or right shell before the shells are closed. This results in complex assembly, increased assembly costs, and the need for additional molds for producing the left and right shells and the motor bracket, further increasing production costs. Utility Model Content

[0005] The purpose of this utility model is to provide an electric motor mounting structure and a hair dryer, which solves the problems of complex air duct structure, complicated assembly, and increased assembly and production costs of current hair dryers.

[0006] To achieve the above objectives, this utility model provides an electric motor mounting structure, including a duct, a motor base, and a motor. The duct has a first positioning portion and at least two outwardly extending hooks at its ends, with hooks at their free ends. The motor base includes an outer sleeve, an inner sleeve, and reinforcing ribs. The inner sleeve is disposed within the outer sleeve, and multiple reinforcing ribs connect the inner sleeve and the outer sleeve, forming a duct between them. The outer sleeve has a second positioning portion at its end that mates with the first positioning portion. The hooks extend into the outer sleeve, and the hooks are limited to the end of the reinforcing ribs, fixing the outer sleeve to the end of the duct. The inner sleeve has a limiting plate at its end, the motor is fixed within the inner sleeve, and the motor's main shaft passes through the limiting plate.

[0007] Furthermore, the second positioning part is a positioning groove provided at the end of the outer sleeve, and the first positioning part is a protrusion extending into the positioning groove.

[0008] Furthermore, the end of the rib away from the air duct is tilted or bent to one side and forms a guide surface, which is used to compress the hook for elastic deformation.

[0009] Furthermore, one end of the stiffener extends out of the outer sleeve, and the outer side of the stiffener is provided on the support portion. The support portion is integrally connected to the end of the outer sleeve, and the support portion is used to support the inner side of the air duct.

[0010] Furthermore, the end of the air duct near the outer casing is a cone, and the support portion is provided with a supporting slope.

[0011] Furthermore, the hook includes a connecting portion that extends to the inner wall of the cone.

[0012] Furthermore, a support column is provided on the inner side of the outer jacket, the support column extends along the axial direction of the outer jacket, and the stiffening plate connects the support column.

[0013] Furthermore, one end of the inner sleeve extends out of the outer sleeve and is provided with multiple opening slots, with an elastic clamping part formed between adjacent opening slots for clamping the motor.

[0014] Furthermore, the cross-section of the closed end of the opening groove does not intersect with the stiffener at least.

[0015] The electric motor mounting structure provided in this embodiment of the utility model has at least the following technical effects:

[0016] 1. The motor can be assembled into the inner sleeve of the motor mount, and then the motor mount can be combined with the air duct. Specifically, the first hook extends into the outer sleeve, so that the hook part hooks onto the end of the rib plate, and the first positioning part and the second positioning part are positioned and engaged to realize the combination of the motor and the air duct, making the assembly convenient and simple. This can improve assembly efficiency and reduce costs.

[0017] 2. The air duct of this electric motor mounting structure can be an integrated structure, so only one set of production molds is needed for the air duct, which reduces production costs. Attached Figure Description

[0028] In one embodiment of the hair dryer of this utility model, please refer to... Figures 1 to 5The hair dryer includes an electric motor mounting structure, specifically, the electric motor mounting structure can be located inside the handle of the hair dryer. The electric motor mounting structure includes an air duct 100, a motor base 200, and a motor 300. The end of the air duct 100 is provided with a first positioning part 101 and at least two outwardly extending hooks 110, the free ends of which are provided with hook portions 111. The motor base 200 includes an outer sleeve 210, an inner sleeve 220, and ribs 230; the inner sleeve 220 is located inside the outer sleeve 210, and multiple ribs 230 connect the inner sleeve 220 and the outer sleeve 210, forming an air duct 201 between the inner sleeve 220 and the outer sleeve 210. The end of the outer sleeve 210 is provided with a second positioning part 202 that cooperates with the first positioning part 101. The hooks 110 extend into the outer sleeve 210, and the hook portions 111 are limited at the end sides of the ribs 230, thus fixing the outer sleeve 210 to the end of the air duct 100. The inner sleeve 220 has a limiting plate 221 at its end. The motor 300 is fixed inside the inner sleeve 220, and the main shaft of the motor 300 passes through the limiting plate 221. Therefore, the air duct and motor assembly structure of the hair dryer in this embodiment is simple and easy to assemble. It can improve assembly efficiency and reduce costs. In addition, the air duct 100 in this embodiment can be a one-piece structure, so only one set of production molds is needed for the air duct 100, thus reducing production costs.

[0029] For further details, please refer to... Figures 1 to 5 The second positioning part 202 is a positioning groove provided at the end of the outer sleeve 210, and the first positioning part 101 is a protrusion extending into the positioning groove. In this embodiment, after the outer sleeve 210 and the air duct 100 are assembled, the hook 210 and the rib plate 230 limit the movement, and with the cooperation of the protrusion and the positioning groove, the outer sleeve 210 is fixed to the end of the air duct 100 and remains fixed.

[0030] For further details, please refer to... Figures 1 to 5 The end of the rib 230 away from the air duct 100 is tilted or bent to one side, forming a guide surface 231. The guide surface 231 is used to compress the hook 110 for elastic deformation. Specifically, when the outer sleeve 210 is assembled with the air duct 100, when the hook portion 111 of the hook 110 contacts the guide surface 231, the protrusion extends into the positioning groove, causing the hook 110 to elastically deform. When the hook portion 111 moves to the end of the rib 230, it elastically resets, thus limiting the hook portion 111 to the end of the rib 230. This fixes the outer sleeve 210 to the air duct 100. Preferably, the end of the rib 230 is curved in an arc shape, so the curved part of the rib 230 can be used to guide and buffer the airflow, and form a rotating airflow effect, avoiding the airflow from impacting the heating wire, but instead allowing it to pass through the heating wire by air pressure compression, thereby reducing noise.

[0031] For further details, please refer to... Figures 1 to 5One end of the stiffening plate 230 extends out of the outer sleeve 210, and the outer side of the stiffening plate 230 is provided on the support part 232. The support part 232 is connected to the end of the outer sleeve 210 as a whole. The support part 231 is used to support the inner side of the air duct 100. This increases the stability of the connection between the motor seat 200 and the air duct 100.

[0032] For further details, please refer to... Figures 1 to 5 The end of the air duct 100 near the outer casing is a cone, and the support part 232 is provided with a support slope. This allows the support part 232 to fit taperedly with the air duct 100, and under the pull of the hook 110, the support part 232 and the inner wall of the air duct 100 are tightly fitted, increasing the stability of the fit between the two.

[0033] For further details, please refer to... Figures 1 to 5 The hook 110 includes a connecting portion 112 that extends to the inner wall of the cone.

[0034] For further details, please refer to... Figures 1 to 5 The inner side of the outer jacket 210 is also provided with a support column 211, which extends along the axial direction of the outer jacket 210. The stiffening plate 230 connects to the support column 211. The connection between the stiffening plate 230 and the outer jacket 210 increases the strength of the connection between the stiffening plate 230 and the support column 211.

[0035] For further details, please refer to... Figures 1 to 5 One end of the inner sleeve 220 extends out of the outer sleeve 210 and is provided with multiple opening slots 222. An elastic clamping part is formed between adjacent opening slots 222 for clamping the motor 300. Therefore, the motor 300 can be clamped and fixed by the clamping force of the other elastic clamping part, without the need to use screws or clips to fix the motor 300, making assembly simpler and more convenient.

[0036] For further details, please refer to... Figures 1 to 5 The cross section of the closed end of the opening slot 222 does not intersect with the stiffener 230 at least. In this embodiment, after the outer jacket 210 and the air duct 100 are assembled, the force exerted by the air duct 100 on the stiffener 230 will not be applied to the elastic clamping part, thus avoiding the problem of excessive clamping force of the elastic clamping part on the motor 300.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
