[0031] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0032] like Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 as well as Figure 6 As shown, the present invention provides a hair dryer and straightener, comprising: a hair dryer body 1 and a movable component 2.

[0033] The hair dryer body 1 includes a housing 11, a guide member 12, a fixing sleeve 13, a rotating sleeve 14, a heating element 15, and a driving member 16. The side wall of the housing 11 has a first air outlet 111, a second air outlet 112, and an air inlet 113. The guide member 12 is disposed inside the housing 11, with its air inlet end facing the air inlet 113. The fixing sleeve 13 is fixedly disposed inside the housing 11, with its open end facing the air outlet end of the guide member 12. The fixing sleeve 13 has a third air outlet 131 and a fourth air outlet 132, with the third air outlet 131 facing the first air outlet 111 and the fourth air outlet 132 facing the second air outlet 112. The rotating sleeve 14 is sleeved outside or inside the fixing sleeve 13, and has a fifth air outlet 141. The heating element 15 is disposed inside the housing 11, with at least a portion of the heating element 15 extending into the fixing sleeve 13 or the rotating sleeve 14. The driving component 16 is connected to the rotating sleeve 14. The rotating sleeve 14 can rotate relative to the fixed sleeve 13 under the drive of the driving component 16, so that the first air outlet 111, the fifth air outlet 141 and the third air outlet 131 are connected in sequence or the second air outlet 112, the fifth air outlet 141 and the fourth air outlet 132 are connected in sequence.

[0034] The movable component 2 is hinged to the housing 11. The movable component 2 includes a rotating arm 21, a heat-conducting plate 22, and a heating element 23. One end of the rotating arm 21 is hinged to the housing 11, and the rotating arm 21 has a sixth air outlet 211. The movable component 2 has an open state and a closed state. When the movable component 2 is in the closed state, the sixth air outlet 211 communicates with the first air outlet 111. The heat-conducting plate 22 is disposed on the rotating arm 21. When the movable component 2 is in the closed state, the heat-conducting plate 22 faces the second air outlet 112. The heating element 23 is disposed inside the rotating arm 21 and corresponds to the heat-conducting plate 22.

[0035] In some preferred embodiments, when the rotating sleeve 14 is fitted over the fixed sleeve 13, the open end of the fixed sleeve 13 has a mounting plate 133, and the inner sidewall of the housing 11 is provided with a slot 114, and the mounting plate 133 is engaged in the slot 114.

[0036] In practical applications, a control circuit board is provided inside the housing 11. The control circuit board is located between the guide member 12 and the heating member 15. Both the guide member 12 and the heating member 15 are electrically connected to the control circuit board. The following is a specific explanation of how the hair dryer and hair straightener achieve the functions of drying and styling, taking the rotating sleeve 14 fitted outside the fixed sleeve 13 as an example.

[0037] When you need to use the hair drying function of the hair dryer straightener, first, make sure that the active component 2 is in the off state (e.g., Figure 2 As shown), at this time, the first air outlet 111 is connected to the sixth air outlet 211; next, the control drive 16 drives the rotating sleeve 14 to rotate, so that the fifth air outlet 141 is connected to both the first air outlet 111 and the third air outlet 131 (so that the hair dryer is in the first blowing state, such as...). Figure 5 (As shown); Finally, the airflow guide 12 is activated by the control button connected to the control circuit board on the side wall of the housing 11, so that the outside air enters the housing 11 through the air inlet 113. The fixing sleeve 13 can guide and converge the airflow, so that the air inside the housing 11 enters the fixing sleeve 13 through the opening end of the fixing sleeve 13 and then blows out in sequence through the third air outlet 131, the fifth air outlet 141, the first air outlet 111 and the sixth air outlet 211. This not only ensures sufficient airflow, but also reduces noise (compared to the existing hair dryers that use the inner cavity of the housing for airflow guidance), so as to achieve a good drying effect and user experience. It can be understood that the heating element 15 can be activated at the same time as the airflow guide 12 is activated, so that the air entering the housing 11 is heated by the heating element 15 and then blown out in sequence through the third air outlet 131, the fifth air outlet 141, the first air outlet 111 and the sixth air outlet 211. In this way, the blown-out air is hot air, which can improve the drying efficiency.

[0038] When the styling function of the hair dryer is needed, the control drive 16 drives the rotating sleeve 14 to rotate, so that the fifth air outlet 141 is connected to the second air outlet 112 and the fourth air outlet 132 (that is, the hair dryer is in the second blow-drying state, such as...). Figure 6 As shown), the air entering the housing 11 enters the fixed sleeve 13 through the opening end of the fixed sleeve 13, and then passes through the fourth air outlet 132, the fifth air outlet 141 and the second air outlet 112 in sequence to be blown out and act on the hair that passes between the hair dryer body 1 and the movable component 2 and is held by the hair dryer body 1 and the movable component 2, ensuring sufficient airflow during hair styling to achieve a good hair styling effect.

[0039] It is understandable that when styling hair, the heating element 15 or the heating body 23 can be de-energized, and the hair can still be styled under the action of cold air and hot heat-conducting plate 22 or hot air and cold heat-conducting plate 22. However, in order to ensure the styling effect, the heating element 15 and the heating body 23 are usually energized at the same time.

[0040] Through the above technical solution, the air entering the housing 11 can be concentrated and blown out from the first air outlet 111 or the second air outlet 112 under the action of the fixed sleeve 13 or the rotating sleeve 14. This not only increases the air force blown out from the first air outlet 111 or the second air outlet 112, but also reduces noise, which greatly improves the performance of the hair dryer and straightener, thereby ensuring a good hair styling effect and user experience.

[0041] Understandably, in order to achieve better hair styling results, multiple first air outlets 111 and multiple second air outlets 112 can be set. Correspondingly, multiple third air outlets 131, multiple fourth air outlets 132, multiple fifth air outlets 141 and multiple sixth air outlets 211 can also be set. The multiple first air outlets 111, multiple second air outlets 112, multiple third air outlets 131, multiple fourth air outlets 132, multiple fifth air outlets 141 and multiple sixth air outlets 211 are all arranged in a straight line.

[0042] Specifically, the aforementioned flow guide 12 includes a motor and fan blades mounted on the motor output shaft. The heating element 15 can be a heating wire. The heating body 23 can be a heating plate.

[0043] Specifically, the aforementioned driving component 16 is a knob, with at least a portion of the driving component 16 exposed outside the housing 11. Thus, the user can manually rotate the driving component 16 to drive the rotating sleeve 14 to rotate, achieving switching easily and conveniently. Alternatively, the driving component 16 can be a motor. When a motor is used, switching is achieved by controlling the forward and reverse rotation of the motor to drive the rotating sleeve 14 to rotate.

[0044] like Figure 3 and Figure 7 As shown, in some preferred embodiments, the inner wall of the fixed sleeve 13 or rotating sleeve 14 has an air guiding surface 136, and the height of the air guiding surface 136 near the closed end of the fixed sleeve 13 is higher than the height of the air guiding surface 136 near the open end of the fixed sleeve 13. This technical solution allows the air guiding surface 136 to guide the air entering the fixed sleeve 13 or rotating sleeve 14, enabling the air to be efficiently gathered and evenly blown out from the first air outlet 111 or the second air outlet 112 under the action of the air guiding surface 136, further improving the hair styling effect.

[0045] like Figure 7As shown, in some preferred embodiments, the outer wall of the closed end of the fixed sleeve 13 is provided with a rotating shaft 134, and the inner wall of the closed end of the rotating sleeve 14 is provided with a slot 142, into which the rotating shaft 134 extends. This technical solution ensures the rotational accuracy of the rotating sleeve 14, preventing deviation of the rotating sleeve 14 from causing a misalignment between the third air outlet 131 or the fourth air outlet 132 and the fifth air outlet 141 during use, thus affecting the airflow effect.

[0046] like Figure 8 and Figure 9 As shown, in some preferred embodiments, the side wall of the opening end of the aforementioned fixing sleeve 13 is provided with multiple mounting slots 135, and the heating element 15 is secured in the multiple mounting slots 135. This technical solution facilitates the quick installation of the heating element 15 into the fixing sleeve 13, effectively improving installation efficiency.

[0047] like Figure 4 , Figure 5 and Figure 6 As shown, in some preferred embodiments, the inner wall of the housing 11 is provided with a first limiting portion 115 and a second limiting portion 116, and the outer wall of the rotating sleeve 14 is provided with a first limiting rib 143 and a second limiting rib 144. The rotating sleeve 14 is driven by the rotating member 16 to make the first limiting rib 143 abut against the first limiting portion 115 or the second limiting rib 144 abut against the second limiting portion 116. With this technical solution, when the hair dryer and straightener switch between the first drying state and the second drying state, that is, when the rotating sleeve 14 rotates under the drive of the driving member 16, the first limiting rib 143 cooperating with the first limiting portion 115 or the second limiting rib 144 cooperating with the second limiting portion 116 can limit the rotating sleeve 14, so that the third air outlet 131 or the fourth air outlet 132 corresponds precisely to the fifth air outlet 141.

[0048] like Figure 1 and Figure 6 As shown, in some preferred embodiments, the hair dryer body 1 further includes a rotatable rotating rod 17, at least a portion of which protrudes from the housing 11 and is located on one side of the first air outlet 111 and the second air outlet 112. This technical solution allows the rotating rod 17 to rotate as the user pulls the hair straightener from the roots to the ends (i.e., when using the styling function of the hair straightener), reducing the pulling force on the hair and improving the user experience.

[0049] like Figure 4 and Figure 6As shown, in some preferred embodiments, the housing 11 is provided with a mounting base 18, which has a groove 181 that matches the shape of the rotating rod 17. The portion of the rotating rod 17 located inside the housing 11 is situated within the groove 181. This technical solution not only facilitates the installation of the rotating rod 17 but also ensures smooth rotation of the rotating rod 17.

[0050] In summary, in one or more embodiments of this utility model, the hair dryer straightener of this utility model, through the cooperative arrangement of the fixed sleeve and the rotating sleeve, and by allowing at least a portion of the heating element to extend into the fixed sleeve or the rotating sleeve, enables the air to converge and be concentrated and blown out from the first air outlet or the second air outlet under the action of the fixed sleeve or the rotating sleeve. This not only increases the air force blown out from the first air outlet or the second air outlet, but also reduces noise, thereby ensuring a good hair styling effect and user experience.

[0051] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
