[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0028] As Figures 1-3 shown, the utility model provides a curl sleeve, including shell cover 1, the outer wall of shell cover 1 is equipped with a plurality of first air outlet 2, one end of shell cover 1 is equipped with air inlet 3, shell cover 1 is equipped with a plurality of respectively with first air outlet 2 and air inlet 3 communication air duct 4, air duct 4 with first air outlet 2 all around the central axis L of shell cover 1 annular array is arranged, and each air duct 4 respectively corresponds a first air outlet 2, the outer wall of shell cover 1 is equipped as cambered surface,

[0029] Among them, as Figure 4As shown, since the outer wall of the shell 1 is connected by a plurality of arcs, and the first air outlet 2 is arranged between adjacent arcs, so that the airflow flowing out of the first air outlet 2 flows along the arc of the shell 1, realizing the airflow flowing around the outer wall of the shell 1, and the airflow flowing out of the first air outlet 2 generates stable Coanda effect, that is, the purpose of realizing the adsorption effect of the outer wall of the shell 1 is achieved.

[0030] The outflow directions of the first air outlets 2 are relatively consistent, that is, the airflow flowing out of the first air outlets 2 rotates clockwise or counterclockwise along the peripheral wall of the shell 1, so that the airflow flowing out of the first air outlets 2 forms a wall-attached circulation 13 on the peripheral wall of the shell 1. When the user holds the curling sleeve towards the hair, the hair is adsorbed on the outer wall of the shell 1 due to the adsorption effect of the shell 1, and is guided by the wall-attached circulation 13, so as to achieve the purpose of automatically adsorbing the hair on the curling sleeve, and reduce the operation difficulty of the user.

[0031] As shown in the figure, Figure 5 The shell 1 is further provided with a connecting column 11 arranged along the axis L direction, and the connecting column 11 is provided with a heating element 111. The shell 1 and the connecting column 11 are both metal materials with good thermal conductivity. The heating element 111 transmits heat to increase the temperature of the shell 1, the connecting column 11 and the airflow, so that the hair wound on the shell 1 is easy to be curled due to the heat. The use of the heat-conducting material makes the heat transfer efficiency of the heating element 111 higher, greatly reducing the waiting time of the user for temperature rise.

[0032] Specifically, as shown in the figure, Figure 4 The outflow direction of the first air outlet 2 is tangent to the outer wall of the shell 1, so that the airflow flowing out of the first air outlet 2 is less scattered, and the wall-attached circulation 13 formed by the airflow flowing out of the first air outlet 2 has stronger adsorption effect.

[0033] Further, as shown in the figure, Figure 3 The first air outlet 2 is provided with a support block 21 at the middle of its length direction, so as to support and fix the opening angle of the first air outlet 2, so that the opening of the first air outlet 2 is not easy to be bent and deformed or even damaged due to external force pressing or impact, facilitating the transportation and installation of the curling sleeve. At the same time, the arrangement of the support block 21 divides the first air outlet 2 into two ends with the support block 21 as the center, so that the air outlet of the first air outlet 2 is more uniform.

[0034] In this embodiment, the first air outlet 2 is also provided with a support block 21 at both ends along the length direction, so that the opening of the first air outlet 2 has more stable support and fixing effect.

[0035] Further, as shown in the figure, Figure 7As shown, the air duct 4 is provided with a wind guide 41, and the wind guide 41 is provided with a plurality of second air outlets 5, one end of the second air outlet 5 is communicated with the air duct 4, and the other end is communicated with the first air outlet 2, and a plurality of second air outlets 5 on the same wind guide 41 are equidistantly arranged along the length direction of the wind guide 41, so that the airflow is discharged from the inside of the relatively high-temperature air duct 4 through each second air outlet 5 respectively, and then flows to the relatively low-temperature first air outlet 2, effectively improving the dispersion and uniformity of the airflow, realizing the multi-point and uniform air outlet of the airflow; at the same time, a heat convection process (i.e. the natural convection phenomenon of the fluid spontaneously flowing from high temperature to low temperature due to temperature difference in physics) is formed between the second air outlet 5 and the first air outlet 2, effectively transferring the heat in the air duct 4 to the first air outlet 2, improving the heating speed of the first air outlet 2.

[0036] Preferably, the two ends of the wind guide 41 are provided with first protrusions 411, and the inner wall of the air duct 4 is provided with grooves 42 corresponding to the first protrusions 411, the first protrusions 411 and the grooves 42 are in sliding connection, so as to fix the wind guide 41 in the air duct 4, and the end of the wind guide 41 towards the air inlet 3 is further provided with a second protrusion 412, and the end of the air duct 4 towards the air inlet 3 is further provided with a clamping groove 43, the second protrusion 412 and the clamping groove 43 are clamped, so as to fix the wind guide 41 in the air duct 4, and achieve the fixation of the wind guide 41.

[0037] More preferably, the end surface of the connecting column 11 towards the air inlet 3 is provided with a wind guide block 112, the wind guide block 112 is fixedly connected with the connecting column 11, and the cross-sectional area of the end of the wind guide block 112 close to the air inlet 3 is smaller than that of the end away from the air inlet 3, so that when the airflow enters the air inlet 3 and passes through the wind guide block 112, the wind guide block 112 has a shunt and guiding effect on the airflow.

[0038] Specifically, the wind guide block 112 is conical or triangular pyramid-shaped, and the vertex angle of the wind guide block 112 is towards the air inlet 3; so that after the airflow contacts the conical surface of the wind guide block 112 from the air inlet 3, the airflow flows into each air duct 4 along the guiding direction, thereby increasing the air volume of the air duct 4.

[0039] Further, as Figure 8As shown, the shell 1 is provided with a ring-shaped connecting portion 12 near one end of the air inlet 3, the connecting portion 12 has a diameter larger than that of the shell 1, and an annular step 121 is formed between the connecting portion 12 and the shell 1. Through this design, the limiting function of the hair dryer is achieved, the stability and sealing performance of the overall structure are improved, and the air can be prevented from leaking directly through the gap between the connecting portion 12 and / or the shell 1 without passing through the inside of the shell, thereby ensuring that the air can smoothly and stably enter the air duct 4 from the air inlet 3, and the overall performance and efficiency of the equipment are enhanced.

[0040] Further, as shown in the drawings, Figure 6 As shown, the annular step 121 is provided with a connecting wall 1211 extending in the direction of the connecting portion 12 and having a ring-shaped structure, and the outer wall of the connecting wall 1211 and the inner wall of the connecting portion 12 form a connecting cavity 14 which is detachably connected to the output end of the hair dryer. This design allows the output end of the hair dryer to be easily inserted and fixed in the connecting cavity 14, achieving efficient and stable connection.

[0041] Preferably, the materials of the shell 1 and the connecting column 11 are both aluminum alloy. Since aluminum alloy has better heat conduction effect, the heating element 111 can quickly transfer heat to the surface of the shell 1, and the shell 1 has higher heat conduction efficiency for the airflow. The heating element 111 can be an electric heating device with an internal battery, or a line connected to the power supply of the hair dryer. Of course, the heating element 111 can also be of other configurations.

[0042] The working principle of the utility model is described in detail as follows: during operation, the heating element 111 receives current through the internal battery or the wire connected to the power supply of the hair dryer, so that the heating element 111 is heated. Since the connecting column 11 and the shell 1 are both made of aluminum alloy with excellent heat conduction performance, the heating element 111 can transfer heat to the surface of the shell 1 more efficiently.

[0043] Meanwhile, the connecting cavity 14 connected with the output end of the hair dryer flows in the air flow, the air flow enters each air duct 4 arranged around the central axis L of the shell 1 from the air inlet 3 respectively, the air flow is heated, the air flow contacted by the air guide block 112 is divided and guided, so that the air flow flowing into each air duct 4 flows uniformly to the air guide piece 41, the air flow flows uniformly to the first air outlet 2 through the division and guidance of the second air outlet 5 arranged at intervals on the air guide piece 41, and the air flow is diffused due to the arc surface of the outer wall of the shell 1 and the tangential arrangement of the outer wall of the shell 1 and the first air outlet 2, so that stable Coanda effect is generated, and the air flow discharged from the first air outlet 2 forms the attached wall circulation 13 on the outer peripheral wall of the shell 1 due to the annular arrangement of the first air outlet 2 along the central axis L of the shell 1, so that the attached wall circulation 13 of the shell 1 has stronger adsorption force on the surrounding hair, so that the hair spontaneously winds on the outer wall of the shell 1 along the wind direction of the attached wall circulation 13, and the hair adsorbed on the outer wall of the shell 1 is heated and curled through the heating of the air flow by the shell 1, so that the high-quality hair curling effect is achieved.

[0044] The innovative point of the utility model lies in that stable Coanda effect and attached wall circulation 13 are generated under the joint action of the first air outlet 2 of the outer wall of the shell 1, the air duct 4 arranged in the shell 1, the arc surface design of the outer wall of the shell and the air flow direction around the peripheral wall of the shell 1, the adsorption effect is enhanced, the hair spontaneously winds on the peripheral wall of the shell 1 along the attached wall circulation 13, the design of the air guide piece 41 and the second air outlet 5 ensures the uniformity of the air outlet, and the support block 21 provides stable support and fixing effect for the first air outlet 2.
