Description

Multifunctional high-speed hair dryer and control method Technical Field

[0001] The present invention belongs to the technical field of hair dryers, and in particular relates to a multifunctional high-speed hair dryer and a control method thereof. Background Art

[0002] A hair dryer is composed of a set of heating wires and a small high-speed fan. When powered on, the heating wires generate heat, and the air blown by the fan passes through the heating wires and becomes hot air. To dry hair faster, a high-speed hair dryer is set up, which increases the speed of the hair dryer to make the air flow faster.

[0003] The Chinese patent document with publication number CN204483373U discloses an accessory for a handheld appliance and a handheld appliance, comprising: a handle having a fluid flow path from an inlet to an outlet and a fan unit for sucking fluid into the fluid inlet; and an accessory for attaching to the handle, the accessory comprising a first part and a second part, the first part comprising a first end of the accessory and at least one plate extending from the first end, the second part comprising a second end of the accessory and at least one other plate extending from the second end, wherein when the first part and the second part are connected, at least two grooves are formed between at least one plate and at least one other plate, and the at least two grooves define a fluid outlet for the accessory.

[0004] The handheld device disclosed in the aforementioned patent document can achieve both curling and straightening effects. Specifically, different attachment heads can be replaced. For example, when curling hair, the curling head is mounted on a handle. A fan within the handle generates an airflow directed toward the curling head. This airflow rotates along the outer surface of the attachment head, thereby adsorbing the hair to the outer surface of the attachment head, thereby drying and styling the hair. However, using hot air to heat and style the hair reduces the temperature of the airflow as it travels a distance, thus affecting the curling effect. Furthermore, when curling hair, the hair can only adhere to the attachment in the direction of the airflow, resulting in poor curling results. Similarly, when straightening hair, using hot air combined with a comb to comb the hair results in low straightening efficiency and poor results.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to provide a multifunctional high-speed hair dryer and a control method thereof, so as to solve the problem that the existing high-speed hair dryers are low in efficiency and poor in effect in straightening or curling hair by replacing the accessory head and completely using airflow.

[0041] In one embodiment of the multifunctional high-speed hair dryer of the present invention, please refer to Figures 1 to 3. Specifically, the multifunctional high-speed hair dryer includes: a hair dryer handle 100, a hair dryer 200 and a hair heating and styling device 300.

[0042] 2 and 3 , the hair dryer handle 100 includes a handle shell 110, a circuit board 120, a high-speed blower 130, and an electric heating component 140; an air duct 111 is provided in the handle shell 110, an air inlet 112 is provided at the first end of the handle shell 110, and an air outlet 113 is provided at the second end. The circuit board 120, the high-speed blower 130, and the electric heating component 140 are arranged in the air duct 111, and the circuit board 120 is arranged near the air inlet 112, and the electric heating component 140 is arranged near the air outlet 113. The circuit board is provided with a control circuit and a control button. Controlling the electric heating component 140 and the high-speed blower 130 by the control circuit is conventional technology in the field, so it will not be described in detail in this embodiment. A first contact 114 is also provided at the second end of the handle shell 110, and the first contact 114 is electrically connected to the circuit board 120. Furthermore, the handle shell 110 is a straight-tube structure; when the air cylinder 200 is sleeved on the air outlet 113 , the air outlet 201 is vertically arranged to the air duct 111 .

[0043] 6 and 7 , the hair dryer 200 includes a first connecting sleeve 210 for being mounted on the air outlet 113. A blower port 201 is provided on one side of the hair dryer 200. To blow hair, the hair dryer 200 is mounted on the air outlet 113 of the handle housing 110. The high-speed blower 130 generates airflow, which is then heated by the electric heating assembly 140 and blown out of the blower port 201 of the hair dryer 200, achieving hair drying.

[0044] Referring to Figures 4 and 5 , the hair heating and styling device 300 is connected to the second end of the handle housing 110, replacing the hair dryer 200. Specifically, when the hair heating and styling device 300 is needed, the hair dryer 200 can be removed from the handle housing 110 and the hair heating and styling device 300 can be installed at the air outlet 113 of the handle housing 110. Specifically, one end of the hair heating and styling device 300 is provided with a second connecting sleeve 310, which is designed to be installed over the air outlet 113. The end of the second connecting sleeve 310 is provided with an electrical connector 311, which is designed to connect to the first contact 114, thereby electrically connecting the heating module within the hair heating and styling device 300. The hair heating and styling device 300 can be a straightening comb or a curling iron. A cold air vent 301 is also provided on the outside of the hair heating and styling device 300, which is connected to the second connecting sleeve 310. When the second connecting sleeve 310 is installed over the air outlet 113 of the handle housing 110, the cold air vent 301 is connected to the air duct 111.

[0045] In the above embodiment, when hair needs to be straightened or curled, the hair dryer 200 is removed from the end of the handle housing 110, and the hair heating and styling device 300 with a straightening or curling function is installed at the air outlet 113 of the handle housing 110. The power connector 311 is connected to the first contact 114, thereby energizing the heating module within the hair heating and styling device 300. The hair can then be directly heated and styled by the hair heating and styling device 300. During the styling process, the high-speed fan 130 generates an airflow, which is blown out of the cold air outlet 301 to cool the hair, achieving a cooling effect and improving the hair styling efficiency. Furthermore, when styling the hair, the hair heating and styling device 300 directly heats and styles the hair, thereby enhancing the hair styling effect.

[0046] Specifically, the first contacts 114 are two spring-loaded pins with hemispherical ends that extend from the end of the handle housing 110. The spring-loaded pins are connected to the circuit board 120. The electrical connectors 311 are two conductive blocks located at the end of the second connecting sleeve 310.

[0047] In the control method of the multifunctional high-speed hair dryer of the above embodiment, when the hair heating and styling device 300 is mounted on the air outlet 113 of the handle housing 110, the first contact 114 is electrically connected to the power connector 311, and the control circuit within the handle housing 110 recognizes the hair heating and styling device 300. The control circuit then energizes the heating module within the hair heating and styling device 300, while the heating element 140 within the handle housing 110 is disconnected and cannot be powered. Furthermore, the high-speed blower 130 can only operate at a low speed to deliver air. This prevents excessive airflow from affecting hair styling. Furthermore, during hair straightening or curling, the airflow from the cold air outlet is at room temperature, ensuring a cooling effect on the hair.

[0048] Furthermore, an identification element is provided at one end of the handle housing 110 near the air outlet 113 and is connected to the circuit board 120. This identification element is used to identify the hair heating and styling device 300. Specifically, when the hair heating and styling device 300 is mounted on the air outlet of the handle housing 110, the electric heating component 140 is de-energized, and the high-speed blower 130 rotates at a low speed or not at all. Specifically, in this embodiment, when the hair heating and styling device 300 is installed on the handle housing 110 and powered on, the identification element can detect the hair heating and styling device 300. The control circuit then controls the electric heating module of the hair heating and styling device 300 to energize and generate heat, while the electric heating component 140 within the handle housing 110 is completely de-energized, and the high-speed blower 130 is controlled by the control circuit to operate only at a low speed.

[0049] Further, referring to Figures 2, 4, and 5, the identification element includes two second contacts 115, which are electrically connected to the circuit board 120. Two conductive members 312 are also provided at the end of the second connecting sleeve 310. When the second connecting sleeve 310 is installed in the air outlet 113 of the handle housing 110, the conductive members 312 are electrically connected to the second contacts 115. This forms a current loop between the second contacts 115, the circuit board 120, and the conductive members 312, thereby detecting that the hair heating and styling device 300 is installed in the air outlet 113 of the handle housing 110. Furthermore, a thermistor is connected between the two conductive members 312 to automatically shut off the power if the hair heating and styling device 300 overheats.

[0050] Furthermore, referring to Figures 2 and 3 , the handle housing 110 also has an annular groove 116 at its end. This groove 116 forms an inner ring 116a and an outer ring 116b on the handle housing 110. The inner ring 116a is used to position the first connecting sleeve 210 or the second connecting sleeve 310. Specifically, when the hair dryer 200 is mounted on the air outlet 113 of the handle housing 110, the first connecting sleeve 210 fits over the outer side of the inner ring 116a. When the hair styling device 300 is mounted on the handle housing 110, the second connecting sleeve 310 fits over the outer side of the inner ring 116a. The first contact 114 is located within the annular groove 116. Furthermore, one end of the electric heating assembly 140 extends to the opening of the inner ring 116a. When the first connecting sleeve 210 of the hair dryer 200 fits over the inner ring 116a, hot air can flow fully into the hair dryer 200 and reduce heat loss.

[0051] Furthermore, referring to Figures 2 and 3 , a first engaging portion 117 is provided on the inner side of the outer ring 116b, a second engaging portion 211 is provided on the outer side of the first connecting sleeve 210, and a third engaging portion 313 having the same structure as the first engaging portion 117 is provided on the outer side of the second connecting sleeve 310. The first engaging portion 117 is a retaining groove, and the second engaging portion 211 is a retaining protrusion, or the second engaging portion 211 is a retaining groove, and the first engaging portion 117 is a retaining protrusion. Specifically, when the first connecting sleeve 210 of the hair dryer 200 or the second connecting sleeve 310 of the hair heating and styling device 300 is placed on the inner ring 116a, the first engaging portion 117 cooperates with the second engaging portion 211 or the third engaging portion 313 to connect. Furthermore, the presence of multiple first engaging portions 117, second engaging portions 211, and third engaging portions 313 ensures a more stable connection.

[0052] Further, referring to Figures 1, 2, 6, and 9, the limiting groove includes an introduction section and a limiting section, with the limiting section being arranged at an angle. A limiting portion extends from one side of the limiting protrusion. When the hair dryer 200 or the hair heating and styling device 300 is assembled with the handle housing 110, the limiting protrusion slides into the limiting groove and rotates a certain angle, causing the limiting portion to be retained within the limiting section. The handle housing 110 also includes a sliding button 118, extending from which a stopper 119 is formed. The second connecting sleeve 310 is inserted into the annular groove 116. When the limiting portion is retained in the limiting section, the sliding button 118 can be pushed, causing the stopper 119 to enter the limiting groove and be retained on the side of the limiting protrusion away from the limiting portion. This prevents reverse rotation and ensures the stability of the connection between the hair dryer 200 and the hair heating and styling device 300 and the handle housing 110.

[0053] Furthermore, after the hair heating and styling device 300 is attached to the handle housing 110, a mechanical mechanism can be used to control the high-speed blower 130 to rotate only at a low speed. Specifically, the handle housing 110 is provided with a sliding button (not shown in the figures) with three gear positions for controlling the high-speed blower to rotate at low, medium, and high speeds. A thrust member (not shown) extends from the sliding button and is adapted to extend into the second connecting sleeve 310. A baffle (not shown) is provided within the second connecting sleeve 310 to block the thrust member, ensuring that the sliding button is only in the low speed position or the off state.

[0054] Furthermore, the hair heating and styling device 300 is an embodiment of a hair curler. Specifically, referring to Figure 4 , the hair curler includes a first clamping plate 320 and a second clamping plate 321. A second connecting sleeve 310 is provided at one end of the first clamping plate 320, and the second clamping plate 321 is rotatably connected to the first clamping plate 320. Heating plates 322 are provided on opposite sides of the first clamping plate 320 and the second clamping plate 321. Multiple cold air vents 301 are provided on the outer sides of the first clamping plate 320 and the second clamping plate 321. During curling, the hair is clamped by the first clamping plate 320 and the second clamping plate 321, while the heating plates 322 heat and style the hair. During the curling process, the high-speed fan 130 rotates at a low speed, generating a low-speed airflow. The cold air vents 301 then blow on the hair, cooling the heated hair and accelerating styling efficiency.

[0055] Furthermore, the hair heating and styling device 300 is an embodiment of a hair straightening comb; specifically, referring to Figure 5 , the hair straightening comb includes a cylinder 330, a heating plate 331, and a comb plate 332. A second connecting sleeve 310 is mounted on one end of the cylinder 330, while the other end of the cylinder 330 is closed. A mounting cavity is provided on one side of the cylinder 330, and a comb plate 332 covers the opening of the mounting cavity. The comb plate 332 is equipped with multiple cold air outlets 301 and comb teeth 333. The heating plate 331 is attached to the inner side of the comb plate 332.

[0056] Furthermore, in an embodiment of the air duct 200, specifically referring to Figures 6 and 7, the air duct 200 further includes a barrel 220 and a flow guide 230. The first connecting sleeve 210 is disposed at one end of the barrel 220. A mounting opening 221 is provided on one side of the barrel 220, and the flow guide 230 covers the mounting opening 221. The inner side of the flow guide 230 is provided with a diverter 231 that extends into the barrel 220. The end of the diverter 231 is attached to the other side of the barrel 220, forming two diverter channels within the barrel 220. The air outlet 201 includes two sets of through grooves disposed on the other side of the barrel 220, and the through grooves are connected to the corresponding diverter channels. In this embodiment, the diverter 231 forms two diverter channels within the barrel 220, thereby guiding the airflow and increasing the pressure of the airflow.

[0057] 6 and 7 , the guide member 230 is provided with through holes 232 extending along both ends of the barrel 220. A diverter 231 extends inward along the edge of the through hole 232. A through hole 222 is also provided on the side of the barrel 220 away from the mounting opening 221. The through hole 222 communicates with the through hole 232, and a through groove is provided around the edge of the through hole 222. In this embodiment, when air is blown out of the air outlet 201, a certain negative pressure is generated in the through hole 222, causing external air to enter through the through hole 232 and be blown out of the through hole 222 together with the hot air flow toward the hair.

[0058] 8 , the hair dryer 200 further includes a blower head 240 that covers the opening 222 , thereby further converging the airflow through the blower head 240 and increasing its pressure. Specifically, the blower head 240 includes an outer shell 241 and an inner sleeve 242 . The inner sleeve 242 is disposed within the outer shell 241 and is engaged with the cylinder body 220 . The end of the outer shell 241 is attached to the outside of the cylinder body 220 , and an annular air duct 243 is formed between the outer surface of the inner sleeve 242 and the inner surface of the outer shell 241 . One end of the annular air duct 243 covers the blowing opening 201 .

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
