DETAILED DESCRIPTION

[0031] 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.

[0032] For example Figures 1-2The utility model provides a tubular air nozzle flow guide structure, including casing 1 and detachable installation flow guide piece 2 in casing 1, be equipped with a air inlet 14 and a plurality of circumferential wall annular array of casing 1 is arranged and goes out the hole 15, be equipped with the flow channel 16 of communication of air inlet 14 and the hole 15 of going out of flow guide piece 2 respectively in casing 1, flow guide piece 2 includes the splitter plate 21 and the length direction of flow channel 16 is sequentially fixed on the splitter plate 21 on a plurality of intercepting plate 22, the length direction of intercepting plate 22 and flow channel 16 is perpendicular to set.

[0033] When using, air current enters flow channel 16 from air inlet 14, under the guidance of splitter plate 21 and intercepting plate 22, a large number of air current will first impact on intercepting plate 22, because intercepting plate 22 and the length direction of flow channel 16 are perpendicular to set, so air current will evenly diffuse along the periphery of intercepting plate 22 under the block of intercepting plate 22, and evenly flow from the hole 15 of casing 1, thereby achieving the effect that air is evenly discharged from the periphery of casing 1, so that the effect of hair ironing is better.

[0034] Specifically, as Figures 3-4 The utility model discloses a tubular air nozzle flow guide structure, including casing 1 and detachable installation flow guide piece 2 in casing 1, be equipped with a air inlet 14 and a plurality of circumferential wall annular array of casing 1 is arranged and goes out the hole 15, be equipped with the flow channel 16 of communication of air inlet 14 and the hole 15 of going out of flow guide piece 2 respectively in casing 1, flow guide piece 2 includes the splitter plate 21 and the length direction of flow channel 16 is sequentially fixed on the splitter plate 21 on a plurality of intercepting plate 22, the length direction of intercepting plate 22 and flow channel 16 is perpendicular to set.

[0035] In this invention, the front baffle 221 is closest to the air inlet 14, thus receiving the largest airflow. Since airflow tends to flow backward, setting the diameter D1 of the front baffle 221 to its maximum ensures that a large amount of airflow flows backward from the edge of the front baffle 221 towards the baffle support 223, while some airflow is also blocked by the front baffle 221 and flows out from the air outlet 15. In the prior art, the airflow at this location is often neglected, resulting in a small airflow. When styling hair, the hair at this location often doesn't hold well, requiring a second styling step, which is time-consuming and laborious. Therefore, the guide member 2 of this invention effectively improves this defect, allowing airflow to flow evenly from the periphery of the housing 1, resulting in a better user experience.

[0036] Furthermore, such as Figure 5 As shown, the flow channel 16 is divided into several air chambers 161 by the flow plate 22. Each air chamber 161 is interconnected by the gap between the edge of the flow plate 22 and the inner wall of the housing 1. The air chambers 161 are divided into a front chamber 1611 and several branch chambers 1612 from front to back. The front-to-back length of the front chamber 1611 is smaller than the front-to-back length of the branch chambers 1612. The front cavity 1611 is formed by the distance from the front baffle 221 to the air inlet 14. Therefore, the airflow and air volume at the front cavity 1611 are affected by the position of the front baffle 221. When the distance L from the front baffle 221 to the air inlet 14 increases, the airflow that the front cavity 1611 needs to accommodate will increase. Consequently, the time it takes for the airflow to impact the front baffle 221 and then flow back out from the side will increase accordingly. That is, the airflow velocity from the air outlet 15 located here will decrease accordingly, i.e., the airflow will decrease. When the distance L from the baffle 221 to the air inlet 14 decreases, the airflow that the front cavity 1611 needs to accommodate will decrease. Correspondingly, the time for the airflow to impact the front baffle 221 will be shorter, so the airflow will quickly flow out from the air outlet 15 located there. That is, the airflow at the front cavity 1611 will increase accordingly. Therefore, the distance from each baffle 22 to the air inlet 14 in this utility model is installed after testing and ensuring that the airflow from the air outlet 15 at each location is equal, so as to ensure uniform airflow from the pipe 13.

[0037] Furthermore, in order to make the airflow flow more smoothly in the flow channel 16 and not be too disturbed by the cut-off plate 22, the edges of the cut-off plate 22 of this utility model are all guide slopes 23, which have a guiding effect on the airflow, so that some of the airflow can flow smoothly along the guide slopes 23 into the rear branch cavity 1612, thereby reducing noise.

[0038] Further, as shown in Figure 6 the shell 1 includes a connecting seat 11 provided with the air inlet 14, a support 12 and a pipe passage 13 sleeved on the support 12; the support 12 and the pipe passage 13 are both abutted on one end of the connecting seat 11 away from the air inlet 14, and one end of the connecting seat 11 close to the air inlet 14 is connected with the hair dryer. It is necessary to supplement that the support 12 is provided with a screw hole one 125 on the side wall facing the pipe passage 13, and the pipe passage 13 is provided with a through hole one 132 corresponding to the screw hole one 125; during installation, the pipe passage 13 is sleeved on the support 12, and a bolt is inserted from the through hole one 132 and screwed with the inner wall of the screw hole one 125, so that the pipe passage 13 is screwed and fixed with the support 12.

[0039] Specifically, the air outlet hole 15 is arranged on the pipe passage 13, and the peripheral wall of the support 12 is provided with a plurality of air outlet grooves 121 respectively communicating with the flow channel 16 and the air outlet hole 15; after the airflow flows into the air inlet 14, it passes through the flow channel 16, the air outlet groove 121 and the air outlet hole 15 in turn.

[0040] Further, as shown in Figure 7 the flow guide piece 2 is detachably connected in the support 12, one end of the flow guide piece 2 away from the air inlet 14 is provided with a closing plate 24 abutting with the inner wall of the end part of the support 12, the outer side of the closing plate 24 is provided with a fixing column 25, and the support 12 is provided with a fixing groove 122 corresponding to the fixing column 25; when the fixing column 25 is inserted into the fixing groove 122, it can limit the flow guide piece 2, so as to ensure that the flow guide piece 2 is located at the center of the support 12, thereby further ensuring the uniformity of the airflow divided by the flow guide piece 2. In addition, in order to further enhance the stability of the flow guide piece 2 in the support 12, prevent the fixing column 25 from sliding down from the fixing groove 122 when the flow guide piece 2 is vertically placed, a screw hole two 251 can be arranged in the fixing column 25, the end part of the fixing groove 122 is provided with a through hole two 1221 corresponding to the screw hole two 251, and a bolt is inserted from the through hole two 1221 and screwed with the inner wall of the screw hole two 251, so that the flow guide piece 2 is fixed in the support 12, so that people can use it more safely and more confidently.

[0041] Further, as shown in Figures 8-9As shown in the utility model embodiment, the flow guide piece 2 is composed of two mutually perpendicular and intersecting flow distribution plates 21, one end of the flow distribution plate 21 close to the air inlet 14 is provided with a plurality of convex strips 211 extending towards the inner wall of the support 12, the inner wall of the support 12 is provided with grooves 123 corresponding to the convex strips 211, when the convex strips 211 are clamped into the grooves 123, the other end of the flow guide piece 2 can be further fixed with the support 12, the stability of the flow guide piece 2 is enhanced, so as to prevent the flow guide piece 2 from shaking under the impact of air flow.

[0042] Further, the pipe 13 is made of aluminum or stainless steel with high thermal conductivity, can quickly heat to quickly style or soften the hair, the user does not need to wait for a long preheating time and hair ironing time during the hair curling process, and the quick hair curling effect can be achieved, time is saved, and the needs of people for fast-paced life are met, and the use rate of people is enhanced.

[0043] Specifically, as Figure 10 As shown in the utility model embodiment, in the use process, the peripheral wall of the pipe 13 will heat, in order to prevent scalding, the end of the support 12 away from the air inlet 14 is also provided with an anti-scald cover 124, the anti-scald cover 124 is fixedly connected with the support 12 in a screwing mode, and the anti-scald cover 124 is sleeved on the peripheral wall of the pipe 13, so that people can directly hold the anti-scald cover 124 with the hand when curling the hair for a long time, to relieve the fatigue and soreness of the other hand caused by holding the hair dryer for a long time, and the anti-scald cover 124 is more labor-saving in use; meanwhile, the anti-scald cover 124 can also avoid accidentally scalding others during use, and the safety of use is enhanced.

[0044] Further, the pipe 13 is made of aluminum or stainless steel with high thermal conductivity, can quickly heat to quickly style or soften the hair, the user does not need to wait for a long preheating time and hair ironing time during the hair curling process, and the quick hair curling effect can be achieved, time is saved, and the needs of people for fast-paced life are met, and the use rate of people is enhanced.

[0045] Further, as Figure 11To solve the problem of poor winding effect of hair in the prior art, the shell 1 is provided with a plurality of bristles 17 on the peripheral wall, the bristles 17 are arranged in an annular array along the flow channel 16 and are equidistantly arranged along the length direction of the flow channel 16, in the embodiment of the utility model, the bristles 17 are arranged on the peripheral wall of the support 12, the pipe passage 13 is provided with a plurality of bristle holes 133 for the bristles 17 to extend out, and the bristle holes 133 and the air outlet holes 15 are arranged in a cross direction in the cross section of the flow channel 16. When in use, the hair tips are only wound around the pipe passage 13 once, and the hair can be tightly wound with the bristles 17, and people can continue to wind the remaining hair on the pipe passage 13 by rotating the pipe passage 13, without pressing the hair by hand all the time, so that the hair is more convenient and flexible to use, and the hair will not slide off due to the short length, so that the overall effect of hairdressing is better.

[0046] The working principle of the utility model is described in detail as follows:

[0047] When in use, the airflow flows into the flow channel 16 from the air inlet 14, due to the blockage of the front intercepting plate 221, a large amount of airflow flows along the guide inclined surface 23 of the front intercepting plate 221 to the next branch cavity 1612, and a small amount of airflow flows out from the air outlet hole 15 of the front cavity 1611; since the diameter of the intercepting branch plate 223 behind the front intercepting plate 221 gradually increases, the airflow will correspondingly retain part of the airflow in each branch cavity 1612 while flowing backward, and uniformly flows out from each air outlet hole 15.

[0048] The utility model discloses an innovative point that a plurality of intercepting plates are arranged perpendicularly to the length direction of the flow channel, the flow channel is divided into a plurality of air cavities, the diameters of the intercepting plates are different, and the distances between the adjacent intercepting plates are also different, so that the speed and flow of the airflow flowing through each air cavity are different, the diameters of the intercepting plates and the distances between the adjacent intercepting plates are adjusted to ensure that the air outlet amounts are consistent, the airflow is uniformly distributed, the hairdressing effect is better, and in addition, the bristles are arranged in an annular array on the peripheral wall of the shell, so that the hair is more tightly wound with the air nozzle and is not easy to slide off, the hairdressing efficiency is improved, time and labor are saved, and the utility model is more convenient and flexible to use.
