[0038] The following is combined with Figures 1 - 3 to describe the hair dryer of the present utility model.

[0039] See Figure 1 As shown, the hair dryer according to an embodiment of the present utility model includes a main housing 110, a control board 120, a deflector 122, a heating assembly 130, the main housing 110, and a first wire 121.

[0040] Specifically, the main housing 110 is provided with an air outlet 111 and an air inlet 112. Airflow enters the main housing 110 from the air inlet 112 and exits from the air outlet 111. The air outlet 111 can output warm air or cold air. The control board 120 is disposed inside the main housing 110, and the control board 120 can control the working state of the electrical components inside the hair dryer. The deflector 122 is disposed inside the main housing 110 and is located at the air inlet 112. The deflector 122 is used to split the airflow entering the main housing 110. The heating assembly 130 is disposed inside the main housing 110, and the heating assembly 130 is used to heat the gas inside the main housing 110 so that the air outlet 111 outputs warm air.

[0041] As Figure 2 shown, the deflector 122 and the heating assembly 130 jointly define a main air duct 113, and the deflector 122, the control board 120, and the heating assembly 130 jointly define an auxiliary air duct 114. The air volume of the main air duct 113 is greater than that of the auxiliary air duct 114. Both the main air duct 113 and the auxiliary air duct 114 are communicated with the air inlet 112 and the air outlet 111. The deflector 122 is disposed at the air inlet 112 to respectively guide the gas entering the main housing 110 into the main air duct and the auxiliary air duct 114. As Figure 2 shown, in some embodiments, the deflector 122 is provided with a bending plate 127. The bending plate 127 extends into the air inlet 112 and divides the air inlet 112 into two parts. One part is communicated with the main air duct 113, and the other part is communicated with the auxiliary air duct 114. By setting the position of the bending plate 127, the sizes of the part of the air inlet 112 communicated with the main air duct 113 and the part of the air inlet 112 communicated with the auxiliary air duct 114 are changed, thereby changing the air volumes in the main air duct 113 and the auxiliary air duct 114.

[0042] The first wire 121 connects the heating assembly 130 and the control board 120. The control board 120 controls the heating assembly 130 to be turned on or off through the first wire 121, or controls the heating power of the heating assembly 130, thereby controlling the air outlet temperature. It should be noted that the first wire 121 can be a single wire or a wire group. The first wire 121 is disposed through the auxiliary air duct 114, and the air volume in the auxiliary air duct 114 is less than that in the main air duct 113. In this way, the disturbance of the wire to the airflow can be reduced, thereby reducing the noise during the use of the hair dryer.

[0043] According to the electric hair dryer of the embodiment of the utility model, the main air duct 113 is defined by the guide member 122 and the heating component 130, and the auxiliary air duct 114 is defined by the guide member 122, the control board 120 and the heating component 130. The air volume of the main air duct 113 is greater than the air volume of the auxiliary air duct 114, and the first wire 121 connecting the control board 120 and the heating component 130 is arranged in the auxiliary air duct 114, so as to reduce the disturbance of the first wire 121 to the airflow and reduce the vibration of the first wire 121, thereby reducing the noise of the electric hair dryer.

[0044] See also Figure 2 As shown, according to some embodiments of the present invention, the control board 120 is disposed on one side of the guide member 122, and the heating component 130 is disposed on the other side of the guide member 122, so as to separate the heating component 130 from the control board 120 and prevent the electronic components on the control board 120 from being damaged by high temperature. Figure 3 As shown, the main housing 110 is cylindrical, the air outlet 111 is arranged at one end of the main housing 110, the air inlet 112 is arranged at the bottom of the main housing 110, the control panel 120, the air guide 122 and the heating component 130 are arranged in sequence along the axial direction of the main housing 110, and the heating component 130 is closer to the air outlet 111. A section of the auxiliary air duct 114 is formed in the heating component 130. The heating component 130 includes a heating element 131, which is arranged in the main air duct 113. The heating element 131 can generate heat to treat the gas passing through the surface of the heating element 131. The heating element 131 is arranged in the main air duct 113 to avoid its influence on the auxiliary air duct 114 and causing the temperature in the auxiliary air duct 114 to be too high. For example, the heating element 131 can be located on the periphery of the heating component 130, and the auxiliary air duct 114 is arranged in the heating component 130 to be separated from the heating element 131 to prevent the first wire 121 from being released from the heating element 131 with a higher temperature or from coming into contact with the airflow with a higher temperature, thereby slowing down the aging speed of the first wire 121 and reducing the failure rate. At the same time, the noise problem caused by the aging of the first wire 121 can be avoided.

[0045] According to some embodiments of the utility model, a wire groove is provided on the inner wall of the heating component 130, and the wire groove extends along the axial direction of the heating component 130. A wire hole 128 is provided on the flow guide 122, and the first wire 121 is passed through the wire groove and the wire hole 128. In some embodiments, the cross section of the wire groove is T-shaped, and the width of the opening of the wire groove is smaller than the width of the bottom thereof, so as to limit the first wire 121.

[0046] like Figure 3According to some embodiments of the present invention, the heating component 130 includes a heating module 132 and a fixing bracket 134. The heating module 132 is used to generate heat to heat the gas. The heating module 132 is connected to the control board 120. The fixing bracket 134 is used to fix the heating module 132. The heating element 131 is provided on the heating module 132. The heating module 132 is sleeved on the fixing bracket 134 and connected to the fixing bracket 134. A section of the auxiliary air duct 114 is constructed inside the fixing bracket 134. The outer peripheral wall of the heating module 132 and the inner wall of the main housing 110 together construct a section of the main air duct 113. That is to say, at the heating component 130, the main air duct 113 is located between the heating module 132 and the main housing 110, and the auxiliary air duct 114 is located inside the fixing bracket 134, so as to prevent the air flow temperature in the auxiliary air duct 114 from being too high. As Figure 2 shown, the main housing 110, the guiding member 122 and the fixing bracket 134 jointly define the auxiliary air duct 114. At the fixing bracket 134, the auxiliary air duct 114 is located inside the fixing bracket 134. The peripheral wall of the fixing bracket 134 separates the gas in the auxiliary air duct 114 from the heating module 132, preventing the air flow temperature in the auxiliary air duct 114 from being too high and causing high-temperature wear to the first wire 121, thereby protecting the first wire 121.

[0047] According to some embodiments of the present invention, a first fixing portion is provided on the heating module 132, and a second fixing portion is provided on the fixing bracket 134. The first fixing portion and the second fixing portion are detachably connected. For example, one of the first fixing portion and the second fixing portion is a fixing rib 133, and the other is a fixing groove 135. The fixing rib 133 is inserted into the fixing groove 135 in a pluggable manner. As Figure 3 shown, in some embodiments, both the heating module 132 and the fixing bracket 134 are cylindrical. A fixing groove 135 is provided on the outer peripheral surface of the fixing bracket 134, and a fixing rib 133 is provided on the inner peripheral surface of the heating module 132. Both the fixing rib 133 and the fixing groove 135 extend along the axis direction of the fixing bracket 134. The fixing rib 133 is clamped in the fixing groove 135 to connect the heating module 132 and the fixing bracket 134 and perform circumferential positioning. Among them, both the fixing rib 133 and the fixing groove 135 are multiple. The multiple fixing ribs 133 are spaced apart along the circumferential direction of the heating module 132, and the multiple fixing grooves 135 are spaced apart along the circumferential direction of the fixing bracket 134. One end of the fixing rib 133 has a clamping portion, and the width of the clamping portion is greater than the width of the main body of the fixing rib 133 (as Figure 3As shown, the width direction of the clamping portion and the width direction of the main body of the fixing rib 133 are both along the radial direction of the heating module 132); the length of the fixing groove 135 is equal to the length of the clamping portion (the length of the clamping portion is along the axial direction of the heating module 132). Among them, the main bodies of a plurality of fixing ribs 133 are clamped in the fixing groove 135 to define a cylindrical receiving space, and the diameter of the receiving space is slightly smaller than the diameter of the fixing bracket 134 to fixedly support the fixing bracket 134.

[0048] See Figure 1 And Figure 2 As shown, according to some embodiments of the present invention, the hair dryer further includes a heat insulation cylinder 124. The heat insulation cylinder 124 is arranged at the air outlet 111, the heat insulation cylinder 124 is embedded in the main housing 110, and the outer peripheral wall of the heat insulation cylinder 124 is attached to the inner wall of the main housing 110, as Figure 3 As shown, at least one limiting block 125 is arranged on the outer peripheral wall of the heat insulation cylinder 124, and a groove is arranged on the inner wall of the main housing 110. The limiting block 125 is adapted to be embedded in the groove to limit the heat insulation cylinder 124. The limiting block 125 can be two, and the two limiting blocks 125 are spaced apart along the circumferential direction of the heat insulation cylinder 124 and are symmetrically distributed. The limiting block 125 can extend along the circumferential direction of the heat insulation cylinder 124 to increase the contact area. The heat insulation cylinder 124 can separate the heating component 130 from the main housing 110, reduce the heat transfer between the heating component 130 and the main housing 110, and avoid inconvenient use caused by the overhigh temperature of the main housing 110.

[0049] The heat insulation cylinder 124 is connected to the flow guide member 122 and defines an installation space. The heating component 130 is arranged in the installation space, and one end of the heating component 130 abuts against the flow guide member 122, and the other end abuts against the heat insulation cylinder 124. In this way, the heating component 130 is clamped and fixed by the flow guide member 122 and the heat insulation cylinder 124. During the assembly process, the flow guide member 122, the heating component 130 and the heat insulation cylinder 124 are fixed through a single assembly, without the need for pairwise separate assembly, saving the assembly steps and improving the production efficiency. As Figure 3 As shown, in some embodiments, a boss 123 is arranged on the side of the flow guide member 122 facing the heat insulation cylinder 124, and at least one screw hole is arranged on the boss 123. The flow guide member 122 and the heat insulation cylinder 124 are connected by screws. Alternatively, in some embodiments, the flow guide member 122 and the heat insulation cylinder 124 can be connected by a snap-fit method. For example, a snap-fit block is arranged on the outer peripheral wall of the flow guide member 122, and a snap-fit hole is arranged on the peripheral wall of the heat insulation cylinder 124. When connecting, the snap-fit block is snapped into the snap-fit hole.

[0050] As Figure 1As shown, in some embodiments, the hair dryer further includes a fixing ring 126 and a decorative member 153. The fixing ring 126 is provided at the air outlet 111 and abuts against the heat insulation cylinder 124 to limit the heat insulation cylinder 124 in the axial direction. The decorative member 153 is provided in the heat insulation cylinder 124 and faces the air outlet 111 to block the internal structure of the main housing 110 and improve the aesthetics. A magnetic member 154 can be provided in the heat insulation cylinder. The decorative member 153 is configured to be a structure that can be adsorbed by the magnetic member 154 to fix the decorative member 153 through the magnetic member 154. Such a setting also facilitates the disassembly of the decorative member 153 for maintenance, or is convenient for the user to replace and perform custom settings, etc.

[0051] According to some embodiments of the present invention, the hair dryer further includes a handle and a motor 141. The handle is connected to the main housing 110. An air inlet passage 142 is provided in the handle. The motor 141 is provided in the air inlet passage 142 and is electrically connected to the control board 120 to control the rotation speed of the motor 141 through the control board 120, thereby controlling the wind speed and the air volume entering the main housing 110. The air inlet passage 142 communicates with the air inlet 112, and the outside air enters the main housing 110 through the air inlet passage 142 in the handle. In some embodiments, an adjustment key is provided on the handle. The adjustment key is connected to the control board 120 through a second wire 144. The control board 120 structures the electrical signal of the adjustment key to control the motor 141 and the heating and air supply components.

[0052] Specifically, the handle includes a housing 147, a first inner housing 145, a second inner housing 146, a filter screen 149, and a fine mesh 148. The first inner housing 145 and the second inner housing 146 are connected to define the air inlet passage 142. The motor 141 is provided in the air inlet passage 142 to drive the outside gas to enter the air inlet passage 142 to form an air flow. The adjustment switch is provided on the first inner housing 145 or the second inner housing 146. The housing 147 is sleeved outside the first inner housing 145 and the second inner housing 146. The fine mesh 148 is provided at the inlet of the air inlet passage 142 and is connected to both the first inner housing 145 and the second inner housing 146. The filter screen 149 is sleeved outside the fine mesh 148. The filter screen 149 and the fine mesh 148 jointly filter the gas flowing from the outside to the air inlet passage 142 to reduce or avoid sundries and dust from entering the air inlet passage 142, the main air duct 113, or the auxiliary air duct 114. The handle may further include a noise reduction module 151. The noise reduction module 151 is connected to the motor 141 to absorb the vibration of the motor 141 and reduce the noise.

[0053] According to some embodiments of the present invention, the handle further includes a seal 143. The seal 143 is provided on the inner wall of the handle and is used to seal the adjustment key to prevent dust and the like in the air inlet passage 142 from adhering to the adjustment key and causing damage to the adjustment key. The second wire 144 passes through the seal 143 to fix the second wire 144 and reduce the vibration of the second wire 144. AsFigure 2 As shown, the second inner shell 146 is closer to the air outlet 111 than the first inner shell 145. A key bin 152 is provided on the first inner shell 145, and the adjustment keys are arranged in the key bin 152. The seal 143 is used to seal the key bin 152 to protect the adjustment keys. The control board 120 is arranged on the side of the flow guide 122 away from the air outlet 111. The bending plate 127 divides the air inlet 112 into two parts. One part is on the side of the bending plate 127 away from the air outlet 111 and communicates with the auxiliary air duct 114, and the other part is on the side of the bending plate 127 facing the air outlet 111 and communicates with the main air duct 113. Thus, when the second wire 144 extends from the adjustment keys to the control board 120, it is distributed along the side of the bending plate 127 away from the air outlet 111, reducing the influence of the second wire 144 on the air flow in the air inlet channel 142 and the main air duct 113, thereby reducing the noise.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered within the scope of the claims of the present invention.
