[0023] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] In order to better describe and illustrate the embodiments of the present application, reference may be made to one or more drawings, but the additional details or examples used to describe the drawings should not be considered as limiting the scope of the utility model invention of the present application, any of the currently described embodiments or preferred methods.

[0026] In the description of the present invention, it should be noted that the terms "length", "width", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0028] Since the components of the barrel are designed to be on the same axis, it is easy for air to enter the barrel and take out the heat. However, this design will cause the center of gravity of the barrel to be far away from the handle, which will be more laborious when used for a long time. In view of this, the utility model provides a hair dryer that is easy to hold. Figure 1-3 For an embodiment of the handheld hair dryer provided by the present invention, please refer to Figure 1-3 The hair dryer 100 includes a hair dryer 1 and a handle 2. The hair dryer 1 is elongated, preferably straight, and has a central axis. A motor assembly 11 is fixedly mounted inside the hair dryer 1. The motor assembly 11 drives the fan blades to rotate to generate negative pressure to draw air. The motor assembly 11 includes a motor shaft 112, which is offset relative to the central axis of the hair dryer 1. The handle 2 is connected to the hair dryer 1; the shaft 112 of the motor assembly 11 is offset toward the handle 2. It should be noted that the motor assembly 11 is generally a cylindrical motor with its center of gravity at its central axis, i.e., the shaft 112.

[0029] In the technical solution of the present invention, the motor assembly 11, which accounts for a relatively large proportion of the weight of the hair dryer 100, is installed in the hair dryer 1, and its rotating shaft 112 is offset from the axis of the hair dryer 1, so that the center of gravity of the motor assembly 11 is closer to the handle 2. Therefore, when the user holds the hair dryer 100, the center of gravity of the entire hair dryer 100 is closer to the handle 2 held by the user. It will be more labor-saving to use the hair dryer 100 for a long time, reducing the user's fatigue.

[0030] To enable the motor assembly 11 to draw air into the air duct 1, refer to Figure 3In one embodiment of the present invention, the rotating shaft 112 of the motor assembly 11 is parallel to the axis of the hair duct 1, so when air is inhaled, the air can form a fluid parallel to the hair duct 1, which is smoother and more silky.

[0031] To prevent excessive offset distance from causing loss of airflow, please refer to Figure 3 In one embodiment of the present invention, the distance h between the rotating shaft 112 of the motor assembly 11 and the central axis of the hair duct 1 is 2-6 mm. As a preferred embodiment, in this embodiment, the distance h between the rotating shaft 112 of the motor assembly 11 and the central axis of the hair duct 1 is 4.2 mm.

[0032] See also Figure 1 and 3 It should be noted that, in this embodiment, the handle 2 is connected to the outer wall of the hair dryer 1. To make the center of the entire hair dryer 100 closer to the user's handheld position, in one embodiment of the present invention, the motor assembly 11 is disposed near the connection between the handle 2 and the hair dryer 1, that is, the motor assembly 11 is installed in the hair dryer 1 directly opposite the handle 2.

[0033] See also Figure 3 In one embodiment of the present invention, an air inlet 1a and an air outlet 1b are respectively provided at both ends of the air duct 1. From the air inlet 1a to the air outlet 1b, a motor assembly 11, a circuit board assembly (not shown in the figure), and a heater assembly 12 are sequentially installed in the air duct 1. It should be understood that the motor assembly 11 and the heater assembly 12 are respectively electrically connected to the circuit board assembly to control their operation. In order to avoid uneven air flow due to the misalignment of the motor assembly 11, an inclined plate is connected to the side of the motor assembly 11 away from the handle 2 and the air duct 1 to guide the air to circulate to this side, thereby making the air flowing in the air duct be ejected evenly.

[0034] To enhance the appearance of the hair dryer 100, please refer to Figure 1 and 2 In one embodiment of the present invention, the handle 2 and the hair dryer 1 are both elongated, preferably straight. Furthermore, the axis of the handle 2 and the rotating shaft 112 of the motor assembly 11 are located in the same plane, which allows for a more concentrated force applied to the user when gripping the handle 2. Furthermore, the axis of the hair dryer 1, the axis of the handle 2, and the rotating shaft 112 of the motor assembly 11 are all located in the same plane, so that the center of gravity of the entire hair dryer 100 is aligned with its plane of symmetry.

[0035] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
