[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 air inlet of the hair dryer is blocked, it is possible that no air can enter the body of the hair dryer. Before the thermostat is sensitively disconnected, the heat generated by the heater cannot be discharged in time, which may cause danger.

[0029] In view of this, the utility model provides a hair dryer that prevents wind blocking. Figure 1-5 For an embodiment of the wind-blocking-proof hair dryer provided by the present invention, please refer to Figure 1-5 The hair dryer 100 includes a hair dryer 1 and a housing 2 .

[0030] Specifically, an air inlet 1a and an air outlet 1b are provided at both ends of the hair duct 1, and a motor assembly 11 and a heater assembly 12 are provided inside the hair duct 1. The motor assembly 11 drives the fan blades to rotate to generate negative pressure to draw air, and the heater assembly 12 is provided with a heating resistor wire for heating the air; the outer shell 2 includes a hair duct shell 21 and a handle 22, the hair duct shell 21 is sleeved and installed on the outer periphery of the hair duct 1, the handle 22 is connected to the hair duct shell 21, and the handle 22 and the interior of the hair duct shell 21 can be fluidically connected; wherein, an auxiliary hole 1c is opened near the air inlet 1a of the hair duct 1, and the auxiliary hole 1c fluidly connects the interior of the hair duct 1 and the interior of the handle 22 respectively, and the interior of the handle 22 has a channel connected to the external fluid, so that the hair duct 1 is connected to the outside world through the auxiliary hole 1c.

[0031] In the technical solution of the present invention, the interior of the hair dryer 1 and the interior of the handle 22 are connected through the auxiliary hole 1c. Since the handle 22 is connected to the outside world, when the air inlet 1a is blocked, the auxiliary hole 1c can draw air from the handle 22 into the hair dryer 1, and then discharge it from the air outlet 1b, thereby effectively discharging the heat generated by the heater assembly 12.

[0032] To facilitate the air extraction of the motor assembly 11, refer to Figure 3 In one embodiment of the present invention, the motor assembly 11 is disposed near the air inlet 1a to facilitate rapid air suction.

[0033] Further, in order to facilitate the air to be sucked into the air cylinder 1 from the auxiliary hole 1c, please refer to Figure 3 and Figure 4 In one embodiment of the present invention, an auxiliary hole 1c is provided on the wall of the air duct 1 between the motor assembly 11 and the air inlet 1a. Furthermore, there are multiple auxiliary holes 1c, all of which are small, to prevent the air volume of the air inlet 1a from being affected by an overly large opening 22a.

[0034] To connect the inside of the handle 22 to the outside, please refer to Figure 4 and Figure 5 In one embodiment of the present invention, an opening 22a is provided at the end of the handle 22, and the wire 3 for powering extends to the outside through the opening 22a.

[0035] Further, see Figure 4 and Figure 5 In one embodiment of the present invention, a gap 22b is provided between the wire 3 and the opening 22a, and the gap 22b enables air to flow into the inside of the handle 22, and then enter between the wind cylinder shell 21 and the wind cylinder 1, and then enter the inside of the wind cylinder 1 through the auxiliary hole 1c.

[0036] Please note that Figure 3 In one embodiment of the present invention, a motor assembly 11, a circuit board assembly, and a heater assembly 12 are sequentially arranged in the air duct 1 from the air inlet 1a to the air outlet 1b. 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.

[0037] 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 22 and the hair dryer 1 are both in the shape of an elongated cylinder, preferably a straight cylinder, and the elongated handle 22 can facilitate the passage of air.

[0038] 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.

[0039] 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.
