DETAILED DESCRIPTION

[0021] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0022] See also Figure 1-7The utility model provides an embodiment: a swing mechanism for a hair dryer, comprising a mounting base 1, wherein the mounting base 1 is connected to a swing mechanism 7 provided thereon; the swing mechanism 7 comprises a motor housing 2 and a swing assembly 3 installed on one side of the motor housing 2; the swing assembly 3 comprises a housing 30, a connecting shaft 31 arranged on one side of the housing 30, and a transmission shaft 34 is further arranged on the side of the connecting shaft 31 away from the housing 30; a swing frame 32 is arranged on the connecting shaft 31; wherein the swing frame 32 is connected to the connecting shaft 31 by a first shaft pin 33 provided thereon The motor housing 2 is connected to the shaft 31, and after the swing frame 32 is installed to the connecting shaft 31, the swing frame 32 swings outside the connecting shaft 31 along the central axis of the first shaft pin 33; a sleeve 21 is provided on the motor housing 2, and a second shaft pin 8 is provided to pass through the sleeve 21 and then connected to the swing frame 32, so that the swing frame 32 swings in the sleeve 21 along the central axis of the second shaft pin 8; a motor 24 is also provided in the motor housing 2, and the output shaft of the motor 24 is eccentrically connected to the connecting shaft 31 through the transmission shaft 34.

[0023] Based on this, when the hair dryer is installed on the swing mechanism 7, the rotation of the motor 24 is used to cause one end of the transmission shaft 34 to rotate in the connecting shaft 31. Since the transmission shaft 34 and the connecting shaft 31 are eccentrically connected, the transmission shaft 34 can cause the connecting shaft 31 to continuously and continuously complete the front, back, left and right swinging action under the limitation of the swing frame 32 when rotating. Therefore, while expanding the blowing range of the air outlet, the airflow generated by the hair dryer can be continuously blown to the user in a large range, thereby improving the drying effect of the hair dryer. Among them, the central axis of the first shaft pin 33 and the second shaft pin 8 are perpendicular to each other. In addition, by increasing the inner diameter difference between the outer diameter of the connecting shaft 31 and the inner diameter of the swing frame 32, or by increasing the inner diameter difference between the outer diameter of the swing frame 32 and the inner diameter of the sleeve 21, or by increasing the inner diameter difference between the outer diameter of the connecting shaft 31 and the inner diameter of the swing frame 32 while increasing the inner diameter difference between the outer diameter of the swing frame 32 and the inner diameter of the sleeve 21, the swing range of the swing assembly 3 can be further increased when the motor 24 is working.

[0024] In order to meet the needs of users, adjustment components 20 are further provided on both sides of the motor housing 2, and the rotation angle of the motor housing 2 is adjusted by the adjustment components 20. Under the action of the adjustment components 20, the motor housing 2 can rotate upward or downward on the mounting base 1. When rotating upward, the airflow generated by the hair dryer is prompted to flow upward, and vice versa, when rotating downward, the airflow generated by the hair dryer can be prompted to flow downward, so that the position of the hair dryer outlet can be freely adjusted to meet the needs of users; for example, a taller user rotates the swing mechanism 7 upward; a shorter user rotates the swing mechanism 7 downward.

[0025] In order to ensure that the position of the swing mechanism 7 can always remain unchanged after the position is adjusted, the adjustment component 20 includes a damping shaft 22 and a fixing bracket 23; wherein one end of the damping shaft 22 is fixed to the motor housing 2, and the other side of the damping shaft 22 is connected to the mounting seat 1 through the fixing bracket 23. Based on this, the damping shaft 22 is fixed in the mounting seat 1 through the fixing bracket 23, and the damping shaft 22 is used to facilitate the swing mechanism 7 to rotate upward or downward under the action of external force and lock the position after rotation. wherein the damping shaft 22 is preferably a straight damping shaft.

[0026] On the basis of the above scheme, since a first clamping plate 35 and a second clamping plate 36 are also provided in the shell 30, one end of the first clamping plate 35 and the second clamping plate 36 are hinged in the shell 30, and the back sides of the first clamping plate 35 and the second clamping plate 36 are connected to the inner wall surface of the shell 30 through a spring 37.

[0027] In summary, when the handle of the hair dryer is inserted from top to bottom into the housing 30, the two clamps move backwards. After the handle of the hair dryer is inserted, the two clamps move toward each other under the action of the spring 37 to ensure that the hair dryer can be stably and reliably located in the housing 30. Based on this, the two clamps move toward each other so that the device can store hair dryers with different handle diameters.

[0028] Furthermore, since a limit block 39 is provided on the first clamp plate 35 and the second clamp plate 36, and the limit block 39 abuts against a baffle 310 provided inside the shell 30 to prevent the first clamp plate 35 and the second clamp plate 36 from continuing to unfold, when the limit block 39 abuts against the baffle 310, it is difficult for the two clamp plates to continue to move backwards, so as to avoid the problem of damage to the two clamp plates due to excessive rotation.

[0029] Furthermore, since a cover plate 38 is provided on the shell 30 and is connected to the shell 30 through the cover plate 38 to prevent the other side of the first clamping plate 35 and the second clamping plate 36 from fitting together, a certain gap is always maintained between the two clamping plates to facilitate the power cord of the hair dryer to smoothly enter the shell 30; in addition, the cover plate 38 is buckled on the shell 30, so the installation and replacement of the two clamping plates can be facilitated by disassembling the cover plate 38.

[0030] In order to ensure a reliable connection between the device and a supporting surface such as a wall, the mounting base 1 is connected to a rear cover 9, so that the device is fixed to the wall by passing bolts through the rear cover 9. At the same time, a protrusion 6 is provided on the rear cover 9. Therefore, when the protrusion 6 is against the wall, a space is formed between the protrusion 6 and the wall for winding the power cord of the hair dryer. Therefore, the power cord of the hair dryer can also be wound around the protrusion 6 to realize the storage of the power cord of the hair dryer. In addition, disassembling the rear cover 9 also facilitates the disassembly and assembly of the motor housing 2.

[0031] Furthermore, since the mounting base 1 is also provided with a socket 4 and a switch button 5, the plug of the hair dryer can be directly connected to the socket 4, and the socket 4 can also be powered or disconnected through the switch button 5.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
