[0028] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0029] Next, reference is made to Figures 1 - 7 to describe a nozzle according to an embodiment of the present utility model.

[0030] As Figures 1 - 4 shown, a nozzle according to a first aspect embodiment of the present utility model includes: a cylinder body and an air flow dividing rib.

[0031] An air flow forms an air flow channel in the cylinder body. The air flow dividing rib is disposed in the cylinder body for dividing the air flow in the cylinder body and making the air flow channels formed in the direction from the air inlet to the air outlet of the cylinder body gradually increase.

[0032] With such a setting, through the sequential diversion of the gradually increasing air flow channels, the entire air flow is divided into gradually increasing multiple air flows in the direction from the air inlet to the air outlet, that is, the air flow is in a divergent shape, and finally the blown air flow is relatively uniform. At the same time, the outlet noise is effectively reduced.

[0033] Therefore, by dividing the air flow in the cylinder body through the air flow dividing rib, the air flow channels formed in the direction from the air inlet to the air outlet of the cylinder body gradually increase, realizing the integration and combing of the air flow, thereby avoiding problems such as the generation of turbulent flow, uneven heating, and large noise, and improving the rectifying effect of the nozzle.

[0034] Further, the air flow dividing rib includes: a first dividing rib, and the first dividing rib axially penetrates through the cylinder body to divide the cylinder body into two groups of air flow channels.

[0035] With such a setting, the first dividing rib is arranged to penetrate along the axial direction of the cylinder body, dividing the air flow channel of the cylinder body into two parts, forming two groups of air flow channels, so that the whole beam of air flow is first divided into two beams of air flow, enabling the two divided beams of air flow to smoothly flow through the gradually increasing air flow channels, thereby effectively reducing noise. Moreover, dividing the cylinder body into two groups of air flow channels facilitates further division of each group of air flow channels and reduces the manufacturing difficulty at the same time.

[0036] According to some embodiments of the present invention, the axis of the first dividing rib coincides with the axis of the cylinder body. In other words, as shown in Figure 3 and Figure 4 , the first dividing rib is arranged at the middle position of the cylinder body to divide the cylinder body into two groups of uniform air flow channels, so that the whole beam of air flow is divided into two identical beams of air flow and continues to flow into the interior of the cylinder body.

[0037] Furthermore, the air flow dividing rib further includes: a second dividing rib, which is arranged on the air outlet side of the cylinder body, and the second dividing rib is respectively connected between the first dividing rib and the cylinder body.

[0038] With such a setting, the second dividing rib is arranged at the air outlet part of the cylinder body, and the second dividing rib is respectively connected to the first dividing rib and the inner wall of the cylinder body, so that the second dividing rib further divides the air flow channels divided by the first dividing rib, forming at least three groups of air flow channels at the air outlet part of the cylinder body. This can not only straighten the air flow, reduce noise, but also reduce air flow loss and increase the air flow blowing volume.

[0039] In the embodiment of the present invention, as shown in Figure 3 and Figure 4 , there are six second dividing ribs. On the basis of the two groups of air flow channels, each group of air flow channels is further divided by three second dividing ribs, thus forming eight groups of air flow channels at the air outlet part of the cylinder body. The whole beam of air flow is first divided into two beams of air flow through the two groups of air flow channels, and then is guided and blown out of the cylinder body through the eight groups of air flow channels, making the blown air flow more uniform and reducing noise.

[0040] Of course, the above embodiments are only one example of the present invention, but not limited thereto.

[0041] For example, in the direction from the air inlet to the air outlet of the cylinder body, it can be divided according to the division method of "one divides into two, two divides into four, four divides into eight", and the whole beam of air flow can also be made to diverge and flow gradually.

[0042] Furthermore, the air nozzle further includes: a connecting shaft, which is arranged on the first dividing rib, and the axis of the connecting shaft coincides with the axis of the first dividing rib, and the second dividing rib is respectively connected between the connecting shaft and the cylinder body.

[0043] With such a setting, a connecting shaft is provided on the first dividing rib. Along the axial direction of the cylinder body, the axis of the connecting shaft coincides with the axis of the first dividing rib, that is, the connecting shaft is arranged at the middle position of the first dividing rib. Moreover, both ends of the second dividing rib are respectively connected to the connecting shaft and the inner wall of the cylinder body, which not only facilitates the arrangement of a plurality of second dividing ribs in the circumferential direction around the connecting shaft, but also can improve the connection strength between the first dividing rib and the second dividing rib, as shown in Figure 3 and Figure 4 .

[0044] Furthermore, as shown in Figure 4 and Figure 6 , the connecting shaft is in a gradually expanding shape in the direction from the end close to the air inlet to the other end.

[0045] With such a setting, the connecting shaft is in a gradually widening conical shape in the direction from the end close to the air inlet to the end close to the air outlet, which can guide the air flow to diffuse and flow to the peripheral part of the cylinder body, preventing the air flow from always gathering and flowing near the axis of the cylinder body, so as to be conducive to the relatively consistent air flow rates of the air flows gradually divided into multiple bundles.

[0046] Furthermore, as shown in Figure 4 , there is a gap between the end of the connecting shaft close to the air inlet and the end of the first dividing rib close to the air inlet. That is, the end of the connecting shaft close to the air inlet does not extend to the end of the first dividing rib close to the air inlet. With such a setting, as shown in Figure 6 , it is conducive to guiding the air flow at the air inlet to be divided.

[0047] According to some embodiments of the present invention, as shown in Figure 1 , Figure 5 and Figure 6 , a boss is provided at the end of the connecting shaft close to the air outlet, and at least part of the boss protrudes relative to the end face of the air outlet of the cylinder body.

[0048] With such a setting, a part of the boss along its axial direction is located inside the cylinder body, and the other end protrudes from the end face of the air outlet of the cylinder body, which can guide the air flow to gather the air flow towards the middle, thereby increasing the wind pressure.

[0049] According to some embodiments of the present invention, as shown in Figure 1 and Figure 5 , an end cover is provided at the air outlet end of the cylinder body. A through groove is formed on the end cover, and the inner diameter of the through groove is smaller than the inner diameter of the cylinder body. One end of the second dividing rib is connected to the first dividing rib, and at least part of the other end is connected to the groove wall of the through groove.

[0050] With such a setting, a through groove is formed on the end cap to connect to the inside of the cylinder body, so that the through groove becomes the air outlet of the air nozzle. Moreover, the inner diameter of the through groove is smaller than that of the cylinder body, which can guide the air flow to gather the air flow towards the middle at the air outlet, thereby increasing the air pressure. In addition, since the second dividing rib is arranged at the air outlet along the axial direction of the cylinder body, a part of the second dividing rib along its axial direction can be connected to the groove wall of the through groove, and the other part can be connected to the inner wall of the cylinder body inside the through groove.

[0051] Furthermore, the end cap and the cylinder body are integrally formed.

[0052] Furthermore, a connecting plate is provided on the outer periphery of the end cap relative to the cylinder body for fixedly connecting to the main body of the hair treatment device. Specifically, a connecting portion such as a buckle is formed on the connecting plate for snap-fitting and fixing to the main body.

[0053] Furthermore, the first dividing rib, the second dividing rib and the connecting shaft are integrally formed with the cylinder body. In this way, the strength and stiffness of the air nozzle are ensured, and it is also beneficial for installation and replacement.

[0054] According to the air nozzle of the second aspect embodiment of the present invention, the air nozzle includes: a first air duct section, the first air duct section includes at least two groups of air flow channels; a second air duct section, the second air duct section is connected to the air outlet side of the first air duct section, and the second air duct section includes at least three groups of air flow channels.

[0055] With such a setting, the first air duct section and the second air duct section are connected in sequence from the air inlet to the air outlet direction. The first air duct section is formed with at least two groups of air flow channels, and the second air duct section is formed with at least three groups of air flow channels, realizing the integration and sorting of the air flow, thereby avoiding problems such as turbulent flow, uneven heating and high noise, and improving the rectifying effect of the air nozzle.

[0056] According to the hair treatment device of the third aspect embodiment of the present invention, it includes: a main body and an air nozzle, and the air nozzle is connected to the air outlet of the main body.

[0057] Therefore, installing the air nozzle of the first aspect embodiment or the second aspect embodiment of the present invention at the air outlet of the main body enables the air flow flowing through the air nozzle to be integrated and sorted, so that the blown air flow is uniform, ensuring uniform heating, and effectively reducing noise. In addition, an end cap and a protruding boss are provided at the air outlet end of the air nozzle, which can guide the air flow to gather the air flow towards the middle, thereby increasing the air pressure.
