A heat insulation sleeve is sleeved on the outer side of a tuyere body of the anti-scald tuyere of the blower, a limiting wall laterally protrudes out of the tuyere body to axially limit the heat insulation sleeve so as to prevent the heat insulation sleeve from axially dropping out of the tuyere body towards the limiting wall, the end part, close to the limiting wall, of the heat insulation sleeve is gradually thinned but not thinner than the limiting wall, and the protruding degree of the heat insulation sleeve is gradually reduced. The blower comprises a blower body and the tuyere detachably mounted on the blower body, and the tuyere is as described above. According to the anti-scald tuyere disclosed by the utility model, the limiting wall is not thickened, but the end part, close to the limiting wall, of the heat insulation sleeve is thinned, so that the protruding degree of the end part is gradually reduced, and the shape transition between the end part and the tuyere body is more natural on the premise of ensuring the light weight of the tuyere body. As the heat insulation sleeve is only thinned at the end part close to the limiting wall, the heat insulation performance of the heat insulation sleeve cannot be obviously reduced, and the heat insulation sleeve can still keep good heat insulation performance.

Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically to a hair dryer anti-scalding nozzle and a hair dryer. Background Technology

[0002] Hair dryers typically come with a nozzle, which is detachably attached to the hair dryer body and guides the air blown out. Users can remove the original nozzle and replace it with different nozzles to achieve different airflow patterns or styling effects. In hot air mode, the hot air blown out by the hair dryer can cause the nozzle temperature to rise, making it easy for users to get burned when removing the nozzle. The applicant's previously filed utility model patent ZL202222330404.X discloses a scald-proof nozzle. This nozzle has a heat insulation sleeve covering the outside of the nozzle body from back to front. The front end of the nozzle body has a lateral protrusion limiting wall that blocks the heat insulation sleeve from detaching from the nozzle body. When removing the nozzle, the user can hold the heat insulation sleeve without getting burned. If the limiting wall is made too thick, it will add extra weight to the nozzle body and affect the user experience. Therefore, the limiting wall is usually made relatively thin to achieve the lightweight of the nozzle body, while the heat insulation sleeve is relatively thick to ensure that it has good heat insulation performance. This difference in thickness makes the transition between the nozzle body and the heat insulation sleeve less natural and affects the aesthetics. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a hair dryer nozzle that is scalding-proof, allowing for a natural transition in shape between the nozzle body and the heat insulation sleeve while ensuring both are lightweight and provide good insulation. This invention also provides a hair dryer that allows for a natural transition in shape between the nozzle body and the heat insulation sleeve while ensuring both are lightweight and provide good insulation.

[0004] To solve the above-mentioned technical problems, the hair dryer anti-scalding nozzle of this utility model has a heat insulation sleeve on the outside of the nozzle body. The nozzle body protrudes laterally with a limiting wall to axially limit the heat insulation sleeve to prevent the heat insulation sleeve from axially detaching from the nozzle body. The end of the heat insulation sleeve near the limiting wall gradually thins but is not thinner than the limiting wall, and its protrusion gradually decreases.

[0005] Furthermore, the heat insulation sleeve is specifically fitted from back to front onto the outside of the nozzle body, and the limiting wall is specifically located at the front end of the nozzle body. It blocks the heat insulation sleeve in front of the heat insulation sleeve to prevent the heat insulation sleeve from axially detaching from the nozzle body. Specifically, the heat insulation sleeve gradually thins at the front end and the degree of protrusion gradually decreases.

[0006] Furthermore, the heat insulation sleeve has raised strips on its sides for people to touch when grabbing the air nozzle.

[0007] Furthermore, the ridges have multiple ridges arranged in parallel.

[0008] Furthermore, multiple convex strips are arranged side by side.

[0009] Furthermore, multiple raised strips are arranged in parallel around the circumference of the main body of the insulation sleeve.

[0010] Furthermore, the length of the convex strip is 5–45 mm, the width is 0.5–2 mm, and the thickness is 0.5–2 mm.

[0011] Furthermore, the thickness of the main body of the heat insulation sleeve is 1-2 mm, and the thickness of the end wall of the heat insulation sleeve near the limiting wall is 0.5-1.5 mm.

[0012] The hair dryer of this utility model includes a body and a nozzle detachably mounted on the body, as described above.

[0013] Furthermore, the nozzle is specifically magnetically mounted on the body.

[0014] The anti-scalding nozzle of this invention does not thicken the limiting wall. Instead, it thins the end of the heat insulation sleeve near the limiting wall, gradually reducing the protrusion of that end. This ensures a more natural transition between the end and the shape of the nozzle body while maintaining its lightweight design. Because the heat insulation sleeve is only thinned at the end near the limiting wall, its heat insulation performance is not significantly reduced, and it still maintains good heat insulation properties.

[0021] The present invention will be further described in detail below with reference to specific embodiments.

[0022] Hair dryer Figure 1The device includes a body 200 and a nozzle 100. The nozzle 100 has an iron ring 101 at its rear end, and a magnet 201 at the front end of the body 200 to magnetically attract the iron ring 101. The nozzle 100 is thus detachably mounted on the body 200 to guide the air blown out by the body 200. See [link / description]. Figure 2 The nozzle 100 is a scalding nozzle, which includes a silicone heat insulation sleeve 2. The heat insulation sleeve 2 is axially fitted onto the outside of the nozzle body 1 from back to front. The front end of the nozzle body 1 has a lateral protrusion of a limiting wall 11, which blocks the heat insulation sleeve 2 in front of it and axially limits the heat insulation sleeve 2. Figure 6 As shown, this prevents the heat insulation sleeve 2 from axially dislodging forward and extending beyond the nozzle body 1. See Figure 3 and Figure 4 The heat insulation sleeve 2 has four sets of protruding strips 22 arranged circumferentially around the main body 20, arranged in a top, bottom, left, and right direction. Each set of protruding strips 22 has seven strips arranged in a front-to-back direction. The length B1 of the top and bottom sets of protruding strips 22 is 7.5–8.5 mm, and the length B2 of the left and right sets of protruding strips 22 is 30–40 mm. See Figure 5 and Figure 6 The four sets of raised strips 22 all have a width D of 1.4mm and a thickness H1 of 1.2mm. In hot air mode, the hot air blown out by the unit 200 and then blown out through the nozzle 100 will cause the temperature of the nozzle body 1 to rise. See Figure 3 Users can remove the nozzle 100 and replace it with different nozzles to obtain different airflow modes or styling effects. When removing the nozzle 100, the thumb rests on the left-hand protrusion 221, the other four fingers rest on the right-hand protrusion 222, and the web of the hand rests on the upper protrusion 223. The hand grasps the heat insulation sleeve 2 in this way and then removes the nozzle 100. The hand directly contacts the protrusion 22 without directly contacting the high-temperature part of the nozzle body 1, so it will not be burned.

[0023] See Figure 6 The main body 20 of the heat insulation sleeve has a thickness H2 of 1.5mm. The front end 21 of the heat insulation sleeve 2 gradually thins but is not thinner than the limiting wall 11, and its protrusion gradually decreases. The thickness H3 of its front wall is 1mm, the same as the thickness of the limiting wall 11. This nozzle 100 does not make the limiting wall 11 thick; instead, it thins the front end 21 of the heat insulation sleeve 2, making its protrusion gradually decrease. This allows for a more natural transition between the shape of the front end 21 of the heat insulation sleeve 2 and the nozzle body 1 while maintaining the lightweight design of the nozzle body 1. Since the heat insulation sleeve 2 only thins at the front end 21, its heat insulation performance is not significantly reduced, and the main body 20 of the heat insulation sleeve still has sufficient thickness to maintain good heat insulation performance.

[0024] See Figure 2In this embodiment, the heat insulation sleeve 2 is fitted onto the outside of the nozzle body 1 from back to front, and the limiting wall 11 is provided at the front end 11 of the nozzle body 1 to prevent the heat insulation sleeve 2 from axially dislodging out of the nozzle body 1. In other embodiments, the heat insulation sleeve 2 can be changed to be fitted onto the outside of the nozzle body 1 from front to back, the limiting wall 11 can be changed to be provided at the rear end of the nozzle body 1, and the heat insulation sleeve 2 can be changed to gradually thin at the rear end.

[0025] See Figure 2 In a non-preferred embodiment, the protrusion 22 can be omitted. When the user disassembles the nozzle 100, he / she can directly touch the outer wall of the heat insulation sleeve 2 with his / her hand to hold the heat insulation sleeve 2. Since the hand is relatively close to the nozzle body 1, the user may feel a slight heat.

[0026] See Figure 3 , Figure 4 and Figure 6 In other embodiments, the lengths B1 and B2 of the protrusion 22 can be changed to any value between 5 and 45 mm, the width D can be changed to any value between 0.5 and 2 mm, and the thickness H1 can be changed to any value between 0.5 and 2 mm.

[0027] See Figure 6 In other embodiments, the thickness H2 of the heat insulation sleeve body 20 can be changed to any value between 1 and 2 mm, and the thickness H3 of the front end 21 of the heat insulation sleeve 2 is less than that of the heat insulation sleeve body 20, and can be any value between 0.5 and 1.5 mm.

[0028] See Figure 6 In this embodiment, the thickness H3 of the front wall of the heat insulation sleeve 2 is 1 mm, which is the same as the thickness of the limiting wall 11. In other embodiments, the thickness H3 of the front wall of the heat insulation sleeve 2 is slightly larger than that of the limiting wall 11. For example, the thickness H3 of the front wall of the heat insulation sleeve 2 is 1 mm, and the thickness of the limiting wall 11 is 0.9 mm.

[0029] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
