Description

hair styling tools Technical Field

[0001] The utility model relates to the field of hairdressing equipment, in particular to a hairdressing device. Background Art

[0002] In daily life, we often use hair straighteners to straighten our hair to achieve a beautiful hair effect. Most traditional hair straighteners simply use a heating plate to clamp the hair, heat it and straighten it. A few hair straighteners also have a blow-drying function, which can dry the hair while straightening it.

[0003] In patents CN114173605A and CN206295032U, when a hair straightener with a blow-drying function is used to dry wet hair, moisture on the wet hair may penetrate into the hair straightener through the blow-drying port, thereby causing a short circuit in the components inside the hair straightener. Utility Model

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a hair straightener that solves the problem of moisture penetrating into the hair straightener through the air outlet and causing a short circuit in the device.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: a hairdressing device comprising two arms, one end of each arm being hinged to each other and each arm having a heating plate; one arm is provided with a first channel for high-speed airflow, and an air outlet of the first channel penetrates the heating plate;

[0006] A second channel for low-speed airflow to blow through and / or drain water is provided in the same arm as the first channel, and the second channel is located beside the air outlet.

[0007] In one embodiment, when the hair styling appliance is a hair straightener, the second channel is a drainage channel; when the hair styling appliance is a hair dryer, the second channel is a low-pressure airflow channel; when the hair styling appliance is used as both a hair straightener and a hair dryer, the second channel is a dual-function channel compatible with drainage and low-pressure airflow.

[0008] In one embodiment, the second channel has an upper through hole and a lower through hole, the upper through hole is located on the surface of the heating plate of the arm, and the lower through hole passes through the corresponding arm.

[0009] In one embodiment, the upper through hole is located at the periphery of the air outlet, and the lower through hole is located on the back side of the corresponding arm.

[0010] In one embodiment, a grid is provided on the upper through hole of the second channel.

[0011] In one embodiment, the outer periphery of the air outlet is generally surrounded by a frame to prevent moisture from entering the first channel.

[0012] In one embodiment, the heating plates are two plates spaced apart from each other, and the two hair straightener heating plates are spaced apart from each other on both sides of the second channel.

[0013] In one embodiment, the second channel includes a left support plate and a right support plate integrally provided in one of the arms, and a cavity-type ditch is formed by the left support plate, the right support plate and the back surface of the arm itself.

[0014] In one embodiment, the first channel is a high-pressure air duct provided in an air duct, and the air duct is used to separate the first channel from the second channel.

[0015] In one embodiment, an air flow channel for guiding the outflow of air is provided on the other arm corresponding to the air outlet; the high-speed air flow forms a high-pressure area on the path through which the air flow passes in the air flow channel, and the area in the air flow channel other than the high-pressure area and the second channel together form a low-pressure area.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0017] By providing a second channel on the same arm as the first channel, when the device scrapes wet hair, the water drips into the second channel from one end and then drains out from the other end, preventing water from seeping into the device through the air outlet and causing internal short circuits. The second channel also provides acceleration space for slow airflow, accelerating it within the second channel and further improving drying efficiency.

[0039] Please refer to Figures 1 to 4 , the present application provides a hair styling device, which is an integrated handheld device that can be used to quickly air-dry hair and straighten hair at the same time.

[0040] A hairdresser includes two arms 10, hinged at one end and equipped with a heating plate 12. One arm 10 is provided with a first channel 21 through which high-speed airflow can pass, and an air outlet 22 of the first channel penetrates the heating plate 12. A second channel 30 is provided within the same arm as the first channel 21, through which low-speed airflow can pass and / or drain. The second channel 30 is located adjacent to the air outlet and extends through the arm 10. The second channel 30 is located adjacent to the air outlet 102. By providing the second channel 30 on the same arm as the first channel, when the device scrapes wet hair, the scraped water falls into the second channel 30 from one end and then drains out from the other end, preventing water from seeping into the product through the air outlet 22 and causing internal short circuits. Furthermore, the second channel 30 provides an acceleration space for the low-speed airflow, accelerating it within the second channel 30.

[0041] In one embodiment, when the hair styling device is a hair straightener, the second channel 30 serves as a drainage channel. When the hair styling device is a hair dryer, the second channel 30 serves as a low-pressure airflow channel. When the hair styling device functions as both a hair straightener and a hair dryer, the second channel 30 serves as a dual-function channel, allowing for both drainage and low-pressure airflow, thus providing diverse functions.

[0042] When the device is used as a hair straightener, the consumer clamps a section of wet hair between the two arms 10 and pulls the device in the direction of the hair extension. The hair straightener heating plate 12 scrapes the wet hair to remove excess unbound water. The scraped water falls into the second channel 30 and is discharged, preventing water from seeping into the interior of the product along the air outlet 22 and causing internal components to short-circuit. The hair straightener heating plate 12 also heats the hair to accelerate the subsequent evaporation of water. During the pulling process, the hair straightener heating plate 12 also straightens the hair for styling.

[0043] When the device is used as a hair dryer, the consumer brings the device close to the hair, and the airflow blown out from the air outlet 22 acts on the hair to dry the hair. At this time, the second channel 30 provides an acceleration space for the low-speed airflow, so that the low-speed airflow is accelerated in the second channel 30, further improving the drying efficiency.

[0044] When used as a hair straightener, the user holds a section of wet hair between the two arms 10 and pulls the device in the direction of the hair. Heat and high-speed air flow simultaneously act on the hair, straightening and drying the hair. The second channel 30 drains water and accelerates the low-speed airflow.

[0045] As shown in Figures 1 and 2, the two arms 10 can optionally be a first arm 101 and a second arm 102. The air outlet 22, first channel 21, and second channel 30 are all located on the first arm 101. Of course, all three can also be located on the second arm 102. When the first and second arms 101, 102 are closed to clamp the hair, the hair can be straightened. Alternatively, when the first and second arms 101, 102 are closed, air from the first channel 21 is blown out of the air outlet 22, and the hair 1 can be air-dried by placing the device close to the hair 1.

[0046] As shown in Figures 2, 3, and 4, in one embodiment, the second channel 30 has an upper through hole 31 and a lower through hole 32. The upper through hole 31 is located on the surface of the arm 10 having the heating plate 12, and the lower through hole 32 passes through the corresponding arm 10. The upper through hole 31 is used to collect moisture and serve as a space for accelerating low-speed airflow, while the lower through hole 32 is used to drain moisture.

[0047] As shown in Figures 2 and 4, in one embodiment of the present application, the aperture of the lower through hole 32 is smaller than the aperture of the upper through hole 31. The large-diameter upper through hole 31 facilitates the collection of moisture and serves as a space for accelerating low-speed airflow, while the small-diameter lower through hole 32 facilitates the drainage of moisture.

[0048] As shown in FIG2 , in one embodiment of the present application, the back surface 103 of the arm 10 is an arc-shaped structure 13, and the plurality of lower through holes 32 are spaced apart in the middle region of the arc-shaped structure 13. By designing the back surface 103 of the first arm 10 as an arc-shaped structure 16 and concentrating the plurality of lower through holes 32 in the middle region of the arc-shaped structure 13, moisture is guided toward the middle by the arc surface, thereby facilitating the drainage of moisture and preventing it from accumulating in the second channel 30.

[0049] In one embodiment, the upper through hole 31 is located on the periphery of the air outlet 22, which can be understood as the second through hole 30 being located beside the air outlet 22, and the lower through hole 32 being located on the back side 103 of the corresponding arm 10. Furthermore, there are two heating plates, and the two hair straightener heating plates 12 are spaced apart and arranged on both sides of the second channel 30. It can be understood as the second through hole 30 being located between the air outlet 22 and the hair straightener heating plate 12. The second through hole 30 effectively increases the distance between the air outlet 22 and the hair straightener heating plate 12, which can effectively prevent high-speed airflow from blowing onto the hair straightener heating plate 12 and affecting the heat.

[0050] As shown in Figures 2-4, in one embodiment of the present application, the plurality of air outlets 22 are arranged in two rows, with each row of air outlets 22 having a second channel 30 disposed on the outside. The second channel 30 is located between the air outlets 22 and the hair straightener heating plate 12. The two second channels 30 effectively collect moisture scraped from the hair straightener heating plates 12 on both sides. For example, the second channels 30 are strip-shaped, and their length is greater than the length of each row of air outlets 102, effectively increasing the opening area of ​​the second channels 30 and ensuring that moisture scraped from different locations falls into the second channels 30.

[0051] As shown in Figures 3 and 4 , in one embodiment, a mesh 40 is provided on the upper through hole 31 of the second channel 30. The mesh 40 effectively reduces the ingress of hair and other impurities into the second channel 30, preventing impurities or hair 1 from clogging the second channel 30 and ensuring smooth drainage of water. For example, multiple meshes 40 are arranged obliquely at the upper opening of the second channel 30, with water inlets formed between adjacent meshes 40.

[0052] As shown in FIG. 4 , in one embodiment of the present application, the grid 40 is provided with a slope 41 for facilitating the flow of liquid into the second channel 30 . The slope 41 guides the water and effectively prevents the water from flowing into the air outlet 22 .

[0053] As shown in Figures 1, 3, and 4, in one embodiment, the outer periphery of the air outlet 22 is provided with a frame 50 to prevent moisture from entering the first channel 21. The frame 50 is higher than the upper opening of the second channel 30, and the frame 50 effectively blocks moisture from entering the air outlet 22. Optionally, the frame 50 is made of soft rubber material.

[0054] In one embodiment, the second channel 30 comprises a left support plate 301 and a right support plate 302 integrally formed within one arm, with the left and right support plates 301, 302 and the back surface 103 of the arm 10 forming a hollow channel. The first channel 21 is a high-pressure air duct within the air duct 20, with the air duct 20 separating the first channel 21 from the second channel 30.

[0055] As shown in Figure 2, in one embodiment, the other arm 10 (the second arm 102) is provided with an airflow channel 23 corresponding to the air outlet 22 to guide airflow. The first channel 21, the air outlet 22, and the airflow channel 23 form an air duct unit. Airflow is transported through the first channel 21, then flows through the air outlet 22 and is discharged into the airflow channel 23, thereby functioning as a hair dryer. The high-speed airflow from the air outlet 21 forms a high-pressure area A1 along its path within the airflow channel 23. The area within the airflow channel 23 excluding the high-pressure area A1 and the second channel 30 together form a low-pressure area A2. The high-speed airflow in the high-pressure area A1 increases the flow rate and velocity of the airflow in the low-pressure area A2. The accelerated airflow in the low-pressure area A2 flows toward the airflow channel 23, further drying wet hair. In addition to draining the hair, the second channel 30 also provides space for the airflow in the low-pressure area A2, allowing the airflow in the low-pressure area A2 to flow longer within the second channel 30, thereby increasing its velocity.

[0056] As shown in FIG2 , optionally, a line L is formed between the two rows of air outlets 22 and the corresponding edges of the rib 50 , and the two lines L extend to the inner wall of the air flow channel 23 , respectively. The high-pressure area A1 is formed between the two lines L.

[0057] Optionally, a blower is provided in the first channel 21, and the blower works to draw external air from the air inlet 24 into the first channel 21 for airflow transport. The blower can be a structure of a motor and fan blades, or other blowing structures.

[0058] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
