Description

Technical Field

[0001] The utility model belongs to the field of hair curling equipment, and in particular relates to a wind suction hair curling nozzle with a replaceable tube cover. Background Art

[0002] With the rapid improvement of people's living standards, people pay more attention to their appearance. Among them, curly hair is one of the main ways to improve people's appearance. In order to make the curling effect better and faster, more and more curling products are born.

[0003] In real life, the hair curling tools commonly used by people include a hair curler and a hair clip used in conjunction with the hair curler. When using the hair curler, the user needs to wrap the hair around the outer wall of the hair curler to keep the hair in a curled state and spray the curled hair with a spray to set the hair. In order to achieve a better hair setting effect, the hair curler needs to be clamped and fixed with a hair clip, so that the hair is continuously wrapped around the hair curler and kept in a curled state for a long time.

[0004] However, in actual use, consumers need to wrap their hair around the curling rollers, which is not only troublesome to operate, but also more cumbersome when using multiple curling rollers at the same time, which is not convenient for consumers to quickly perform hair styling operations. At the same time, the outer wall diameter of the curling rollers themselves is fixed, so the same curling roller cannot shape curls of different curvatures, resulting in a single size of curl waves. If you want to shape curl waves of different sizes, you need to purchase curling rollers of different diameters, which further increases the cost of hair styling for consumers. Utility Model Content

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] like Figure 1-4 As shown, the utility model provides an air suction curling nozzle with a replaceable tube cover, comprising an inner tube 1 and a tube cover 2 used in conjunction with the inner tube 1, the inner tube 1 being provided with an air inlet 11 at one end and an air outlet 12 at the other end, the air outlet 12 being provided with a plurality of inner air outlets 121 around its peripheral wall, the air outlet 12 being further provided with an air inlet cavity 122 inside, the air inlet cavity 122 being communicated with the air inlet 11 and the inner air outlet 121 respectively; the tube cover 2 being sleeved outside the outer peripheral wall of the inner tube 1 and being detachably connected to the inner tube 1, the outer peripheral wall of the tube cover 2 being provided with a plurality of outgoing air outlets 21 with the same opening direction, so that a wall-attached airflow path 211 arranged around the outer peripheral wall of the tube cover 2 is formed on the tube cover 2;

[0043] During use, the air inlet 11 of the inner tube 1 is connected to the air flow output end of the hair dryer (not shown), and then the tube cover 2 is sleeved on the inner tube 1. After the hair dryer is started, the air flow discharged by the hair dryer enters the inner tube 1 from the air inlet 11, passes through the air inlet cavity 122, the inner air outlet 121 and the outgoing air outlet 21 of the tube cover 2 in sequence, and is then discharged along the wall-attached air flow path 211. At this time, after the hair approaches or enters the wall-attached air flow path 211, the hair is automatically and quickly wrapped around the outer peripheral wall of the tube cover 2 under the drive of the air flow, thereby quickly completing the hair curling and fixing operation. Compared with the prior art method of manually wrapping the hair around the curling roller, the present invention can not only complete the winding operation efficiently and quickly, but also complete the automatic adsorption and winding by only placing the hair to be curled close to the wall-attached air flow path 211, thereby greatly improving the convenience of curling the hair for consumers and effectively saving consumers' curling time, so as to achieve a quick and good curling effect.

[0044] It is worth noting that since most hair dryers have a built-in heating function, the airflow in the wall-coated airflow path 211 can be heated, thereby softening and shaping the curly hair. Therefore, when consumers need to quickly curl their hair without spraying styling lotion, they only need to turn on the hot air mode of the hair dryer to achieve a quick curling effect, which is also impossible with existing curling rollers.

[0045] At the same time, when the consumer needs to spray styling lotion on the hair or keep it in a wrapped state for a long time, the tube cover 2 can be separated from the inner tube 1, so that the tube cover 2 can be hung alone on the consumer's hair to continue to maintain the wrapped state and styling; since one inner tube 1 of the utility model can be used in conjunction with multiple tube covers 2, the consumer can perform the winding and hanging curling operations on multiple parts of the hair at the same time, further improving the convenience of curling hair. At the same time, the tube cover 2 can be detached from the inner tube 1 to reduce the load on the hair. The tube cover 2 can also be of different diameters to achieve curls of different sizes.

[0046] like Figure 11-15 As shown, in order to make the airflow discharged by the air outlet 12 transition to the outgoing air outlet 21 of the pipe cover 2 more evenly, the present invention includes but is not limited to the following structural design of the air outlet 12; in order to more clearly express the embodiments and technical solutions of the present invention, the end of the air outlet 12 close to the air inlet 11 is defined as the front, and the end away from the air inlet 11 is defined as the rear, and an axis L3 is provided along the front-to-back direction, and the axis L3 is the axis line passing through the center of the circle of the air inlet 11;

[0047] Specifically, such as Figure 11-13As shown, in one embodiment, the air outlet portion 12 further includes a plurality of air guides 123 and a plurality of ribs 124, wherein the plurality of ribs 124 extend longitudinally in the front-to-back direction and are arranged in a circular array around the axis L3, the air guide 123 is an arc-shaped sheet structure, and its two ends are connected to two adjacent ribs 124, wherein an air outlet slot 125 is formed between two adjacent ribs 124, the air guide 123 is located in the air outlet slot 125 and is arranged in parallel along the longitudinal direction of the front-to-back direction, and the air outlet slot 125 and the air outlet slot 125 are arranged in parallel. The air guide blades 123 are arranged in a circular array around the axis L3, giving the air outlet portion 12 an overall cylindrical structure. Adjacent air guide blades 123 and adjacent ribs 124 together form the inner air outlets 121. The arrangement of the air guide blades 123 and the ribs 124 ensures that the inner air outlets 121 within the air outlet portion 12 are evenly distributed, resulting in a more uniform air flow. Air is discharged from the inner air outlets 121 in a direction perpendicular to the ribs 124, thereby ensuring that the wall-coanda airflow path 211 has a more balanced suction effect on hair.

[0048] Preferably, if Figure 11 As shown, both ends of the air guide plate 123 extend toward the adjacent ribs 124, and the extension direction is perpendicular to the ribs 124, wherein the ribs 124 are parallel to the axis L3, so that the air flow is discharged from the outgoing air outlet 21 in a direction perpendicular to the axis L3;

[0049] Preferably, if Figure 12 As shown in FIG13 , a plurality of air guide blades 123 in the same transverse direction (the longitudinal direction is parallel to the axis L3, and the transverse direction is a direction perpendicular to the longitudinal direction) together form an annular structure and include an upstream opening 1231 and a downstream opening 1232. The airflow discharged from the air inlet cavity 122 passes through the upstream opening 1231 and the downstream opening 1232 in sequence. The diameter of the upstream opening 1231 is smaller than that of the downstream opening 1232. By changing the arrangement positions of the upstream opening 1231 and the downstream opening 1232, the purpose of changing the airflow direction is achieved.

[0050] like Figure 12 As shown, when the upstream opening 1231 faces forward and the downstream opening 1232 faces backward, the airflow flows from the air outlet 12 from the front to the rear. The airflow discharged from the outgoing air outlet 21 flows along the right rear or left rear spiral wall due to the guiding effect of the air guide plate 123.

[0051] like Figure 13As shown, when the upstream opening 1231 faces rearward and the downstream opening 1232 faces forward, the airflow passes through the upstream opening 1231 and the downstream opening 1232 in sequence and is discharged. The airflow discharged from the outgoing air outlet 21 flows along the right front or left front spiral wall due to the guiding effect of the air guide plate 123.

[0052] Specifically, such as Figure 14-15 As shown, in another embodiment, the air outlet portion 12 includes a plurality of air guide blades 123 and a plurality of ribs 124. The ribs 124 are arranged in a circular array along the front-to-back direction with the axis L3 as the center, so that the air outlet portion 12 has a cylindrical structure; air outlet slots 125 are formed between adjacent ribs 124, and the air guide blades 123 are arranged in the air outlet slots 125 and are spaced apart along the front-to-back direction.

[0053] Preferably, if Figure 14 As shown, the two ends of the air guide piece 123 connected to the adjacent rib 124 are respectively a first end 1233 and a second end 1234. The distance D5 from the first end 1233 to the air inlet 11 is less than the distance D6 from the second end 1234 to the air inlet 11, so that the air guide piece 123 is arranged in an inclined shape relative to the axis L3. Through the guiding effect of the air guide piece 123, the airflow discharged from the outgoing air outlet 21 flows along the right rear or left front spiral wall attachment;

[0054] Preferably, if Figure 15 As shown, under the same design structure, the distance D5 between the first end 1233 and the air inlet 11 is greater than the distance D6 between the second end 1234 and the air inlet 11, so that the air guide plate 123 is arranged in an anti-inclined shape relative to the axis L3. Through the guiding effect of the air guide plate 123, the airflow discharged from the outgoing air outlet 21 flows along the left rear or right front spiral wall.

[0055] More preferably, Figure 14 Or as shown in 15, the air guide plates 123 in adjacent air outlet slots 125 are arranged at staggered intervals, that is, the connecting ends of the air guide plates 123 connected to one side of the same rib 124 and the connecting ends of the air guide plates 123 connected to the other side of the same rib 124 are spaced apart from each other and are no longer in the same transverse direction.

[0056] Specifically, such as Figure 2As shown, the duct cover 2 includes a plurality of air guide plates 22, which are arranged in a circular array around the air outlet portion 12. The air guide plates 22 include inner ends 221 offset inwardly and outer ends 222 offset outwardly. A gap is provided between the inner ends 221 of the air guide plates 22 and the outer ends 222 of the adjacent air guide plates 22, forming the outgoing air outlet 21. The design of the inner ends 221 and the outer ends 222 of the air guide plates 22 allows the airflow discharged from the outgoing air outlet 21 to flow along the outer walls of the air guide plates 22. This not only makes the structure of the duct cover 2 simple and easy to produce, but also effectively improves the adsorption and entanglement effect on hair.

[0057] Furthermore, since the tube cover 2 may need to be hung on the consumer's hair for a long time and keep the hair styled, the tube cover 2 is made of aluminum material or hard plastic with a lighter texture and higher durability. While improving the durability and practicality of the tube cover 2, it effectively reduces the excessive pulling feeling of the tube cover 2 on the consumer's hair due to the influence of gravity, thereby further improving the consumer's usage experience.

[0058] Specifically, an annular boss 13 is provided on the outer wall of the inner tube 1 near one end of the air inlet 11, and a connecting groove 14 is provided on the boss 13. One end of the tube cover 2 is provided with a convex ring 23 corresponding to the connecting groove 14. During use by consumers, the convex ring 23 of the tube cover 2 can be inserted into the connecting groove 14 of the boss 13 to complete the installation and fixation of the inner tube 1 and the tube cover 2. Then, the airflow of the hair dryer drives the hair to be wrapped around the tube cover 2, and then the convex ring in the tube cover 2 is inserted. The inner tube 1 and the tube cover 2 are pulled out of the connecting groove 14, thereby completing the separation of the inner tube 1 and the tube cover 2, so that the tube cover 2 can be independently suspended on the consumer's hair to maintain the curl and shape of the hair. At the same time, it is also convenient for the inner tube 1 to be connected to another tube cover 2 to perform a hanging curling operation on another part of the hair. The arrangement of the convex ring 23 and the connecting groove 14 allows the inner tube 1 and the tube cover 2 to be quickly assembled and separated, making it convenient for the consumer to use multiple tube covers 2 at the same time to curl the hair in different parts of the hair, thereby achieving the purpose of rapid styling.

[0059] In order to balance the installation firmness and separation convenience of the inner tube 1 and the tube cover 2, the embodiments of the present invention include but are not limited to the following connection structure of the inner tube 1 and the tube cover 2;

[0060] like Figure 5As shown, the connecting groove 14 is screwed with the convex ring 23, that is, an external thread 231 is provided on the outer or inner circumferential wall of the convex ring 23, and an internal thread 141 matching the external thread 231 is provided in the connecting groove 14. When in use, the inner tube 1 and the pipe cover 2 are fixedly connected by screwing the external thread 231 and the internal thread 141, and the inner tube 1 and the pipe cover 2 can also be separated by rotating in the opposite direction. The operation is simple and fast, further improving the convenience of installation and removal of the inner tube 1 and the pipe cover 2.

[0061] like Figure 6 As shown, the connecting groove 14 is snap-engaged with the convex ring 23, the convex ring 23 is provided with a snap 232, and a snap groove 142 corresponding to the snap 232 is provided in the connecting groove 14. When in use, the inner tube 1 and the tube cover 2 are correspondingly snap-engaged through the snap 232 and the snap groove 142, thereby completing the fixed connection between the inner tube 1 and the tube cover 2. After the hair is wrapped around the tube cover 2, the convex ring 23 is pulled out of the connecting groove 14 by force, so that the inner tube 1 and the tube cover 2 are quickly separated, and at the same time, the relative rotation of the inner tube 1 and the tube cover 2 is effectively prevented from affecting the hair wrapping effect.

[0062] Preferably, in order to facilitate production, the positions of the clamping groove 142 on the connecting groove 14 and the buckle 232 on the protruding ring 23 can also be exchanged with each other.

[0063] like Figure 7 As shown, the connecting groove 14 is magnetically connected to the convex ring 23, and a first magnetic member 233 is provided on the convex ring 23. The connecting groove 14 is provided with a second magnetic member 143 that attracts the first magnetic member 233. When in use, the convex ring 23 on the pipe cover 2 is inserted into the connecting groove 14. The first magnetic member 233 and the second magnetic member 143 attract each other, thereby completing the fixed connection between the pipe cover 2 and the inner tube 1. When the two need to be separated, it is only necessary to pull out the convex ring 23 on the pipe cover 2 in the opposite direction of the connecting groove 14. This is simple and convenient and has a longer service life.

[0064] It should be noted that when any one of the first magnetic member 233 and the second magnetic member 143 is a magnetic material, the other can be a magnetic material or a magnetic conductive material that can attract the magnetic material. Therefore, the fixed structure that enables the convex ring 23 and the connecting groove 14 to attract each other and maintain a magnetic state should be considered within the scope of protection of the present utility model.

[0065] like Figure 8As shown, in order to effectively solve the problem that existing curling rollers cannot create curling effects with different wave sizes, the utility model provides a connection structure that can adapt the same inner tube 1 to tube covers 2 of various diameters, thereby achieving the purpose of creating curling effects with different wave sizes. The connection structure is reasonably and cleverly designed and can effectively facilitate the industrial production of the nozzle kit.

[0066] Specifically, the boss 13 is provided with a plurality of connecting grooves 14, each having different diameters and being coaxially arranged with the axis L3 as the centerline. Therefore, the closer the connecting groove 14 is to the edge of the boss 13, the larger the diameter. At the same time, the convex rings 23 of the tube covers 2 of different diameters correspond one-to-one to the connecting grooves 14 of different diameters. In other words, the closer the connecting groove 14 is to the edge of the boss 13, the larger the diameter of the corresponding tube cover 2, and the larger the curly waves formed. By providing a plurality of connecting grooves 14 of different diameters on the same boss 13, the purpose of forming curly hair of different wave sizes is effectively achieved.

[0067] Furthermore, in an embodiment of the present utility model, the connecting grooves 14 on the boss 13 are provided with two, including an inner groove 15 and an outer groove 16. The inner groove 15 is arranged on the inner side of the outer groove 16, so that the diameter D1 of the inner groove 15 is smaller than the diameter D2 of the outer groove 16. The pipe cover 2 also includes a small tube 24 and a large tube 25. The large tube 25 matches the outer groove 16, and the small tube 24 matches the inner groove 15. Therefore, the diameter D3 of the small tube 24 is smaller than the diameter D4 of the large tube 25.

[0068] When consumers need to increase the curl of their hair, they only need to insert the convex ring 23 in the large tube 25 into the outer groove 16 to achieve a fixed connection between the tube cover 2 and the inner tube 1, thereby achieving a large wave curling effect.

[0069] When consumers need to create a small wavy curly effect, they only need to insert the convex ring 23 in the small tube 24 into the inner groove 15 to achieve a fixed connection between the tube cover 2 and the inner tube 1, and the small wavy curly effect can be achieved;

[0070] By providing the connecting grooves 14 of different diameters to be connected to the tube covers 2 of different diameters, the diameter of the hair winding is changed, thereby achieving the effect of shaping curls of different wave sizes. The process is simple and quick, and one inner tube 1 can be used to complete the use of multiple tube covers 2 of different diameters, effectively reducing the production cost of the inner tube 1, and at the same time effectively increasing the curling speed, facilitating quick styling for consumers, and further improving the consumer's user experience.

[0071] It should be noted that a connecting groove 14 of a fixed specification can also be provided on the boss 13, and the pipe covers 2 of different diameters can also use the convex ring 23 of the same fixed specification, thereby achieving the purpose of the pipe covers 2 of different diameters being detachably connected to the same boss 13 through the connecting groove 14 and the convex ring 23.

[0072] Furthermore, if Figure 16 As shown, a free annular flow cavity 4 is further provided between the inner tube 1 and the tube cover 2. When in use, the airflow discharged from the inner tube 1 passes through the free annular flow cavity 4 and is discharged from the outgoing air outlet 21 of the tube cover 2, and flows along the direction of the wall-coanda airflow path 211.

[0073] The cross-sectional area of ​​the free annular flow cavity 4 when the large tube 25 is used in conjunction with the inner tube 1 is larger than the cross-sectional area of ​​the free annular flow cavity 4 when the small tube 24 is used in conjunction with the inner tube 1 .

[0074] Specifically, in actual application, the boss 13 and the pipe cover 2 are usually fixed by abutting against one surface of the boss 13 and fixing the boss 13 with one surface of the convex ring 23. Therefore, the boss 13 is provided with a first clamping surface 144, and the convex ring 23 is provided with a second clamping surface 234 corresponding to the first clamping surface 144.

[0075] The first clamping surface 144 and the second clamping surface 234 can be connected and fixed by the above-mentioned threaded connection, snap connection and magnetic connection structure;

[0076] Preferably, if Figure 17 As shown, in the above embodiment, the first clamping surface 144 can be the inner side wall, outer side wall or bottom wall of the connecting groove 14, and the second clamping surface 234 can be the inner peripheral wall, outer peripheral wall or bottom wall of the convex ring 23 corresponding to the first clamping surface 144 one by one;

[0077] Preferably, in another embodiment, Figure 18 As shown, the boss 13 is provided with a plurality of connecting platforms 19 of different diameters, and the plurality of connecting platforms 19 are coaxially arranged. In this case, the first clamping surface 144 is provided on the outer peripheral wall of the connecting platform 19. The connecting platforms 19 of different diameters correspond one-to-one with the convex rings 23 of different diameters on the pipe covers 2, and the second clamping surface 234 is provided on the inner peripheral wall of the convex ring 23. When in use, the boss 13 and the pipe cover 2 are connected via the first clamping surface 144 and the second clamping surface 234.

[0078] Preferably, in another embodiment, Figure 19As shown, the boss 13 is provided with a plurality of connecting cavities 191 of different diameters, and the plurality of connecting cavities 191 are coaxially arranged. In this case, the first clamping surface 144 is provided on the inner peripheral wall of the connecting cavity 191. The connecting cavities 191 of different diameters correspond one-to-one with the convex rings 23 of different diameters on the pipe cover 2, and the second clamping surface 234 is provided on the outer peripheral wall of the convex ring 23. When in use, the boss 13 and the pipe cover 2 are connected via the first clamping surface 144 and the second clamping surface 234.

[0079] It should be noted that the connecting groove 14, the connecting platform 19 and the connecting cavity 191 can be a circular structure or a polygonal structure, so that the first clamping surface 144 is also a circular or polygonal structure and abuts against the second clamping surface 234 to achieve corresponding clamping between the boss 13 and the tube cover 2.

[0080] Specifically, such as Figure 9 As shown, in order to better improve the effect of the tube cover 2 on the winding and fixing of the hair, the nozzle kit further includes a clamping member 3. The clamping member 3 is an elastic C-shaped structure and can be clamped and fixed with the outer peripheral wall of the tube cover 2 through elastic changes. When in use, after the hair is wrapped around the outer peripheral wall of the tube cover 2, the clamping member 3 is clamped onto the outer peripheral wall of the tube cover 2. At this time, the hair is located between the tube cover 2 and the clamping member 3, thereby further improving the stability of the hair wrapped around the tube cover 2, thereby improving the curling effect of the consumer's hair;

[0081] Preferably, the clamping member 3 is further provided with two hand-held portions 31 at one end away from the tube cover 2. The hand-held portions 31 protrude outward to form a protrusion shape that is convenient for consumers to grasp with their fingers. Consumers can move the two hand-held portions 31 closer to each other, thereby driving the two clamped ends of the clamping member 3 to open to each other. When the consumer releases the hand, the clamping member 3 resumes the clamping state of the tube cover 2 under the action of its own elastic force, thereby effectively improving the convenience of using the clamping member 3.

[0082] More preferably, the clamping member 3 is made of a soft plastic material that is relatively light and has good elasticity. When hanging, it can effectively improve the clamping and fixing effect of the tube cover 2 while reducing the pulling feeling on the hair.

[0083] Specifically, such as Figure 10 As shown, one end of the tube cover 2 is further provided with a slide-out portion 26, which is annularly arranged around the outer wall of the end of the tube cover 2. The slide-out portion 26 can be a small step structure 261 or a prismatic chamfered structure 262. When a consumer needs to detach hair from the tube cover 2, they only need to slide the hair toward the slide-out portion 26 and push it out of the end of the tube cover 2 to complete the separation of the hair and the tube cover 2. The detachment operation is simple and convenient.

[0084] Specifically, such as Figure 5 As shown, a limiting groove 27 is further provided on the inner wall of the pipe cover 2 away from the end of the convex ring 23, and a limiting portion 17 corresponding to the limiting groove 27 is provided on the end of the inner tube 1 away from the air inlet 11. When in use, the convex ring 23 of the pipe cover 2 is inserted into the connecting groove 14 of the inner tube 1, and the limiting portion 17 is correspondingly engaged with the limiting groove 27, thereby realizing rapid and accurate limiting and fixing of the pipe cover 2 and the inner tube 1, thereby effectively improving the installation convenience and accuracy of the pipe cover 2 and the inner tube 1.

[0085] The following is a detailed description of the working principle of the utility model;

[0086] During use, the air inlet 11 of the inner tube 1 is first connected to the air flow output end of the hair dryer, and then the tube cover 2 and the inner tube 1 are fixedly connected via the convex ring 23 and the connecting groove 14. After the hair dryer is started, the outer peripheral wall of the tube cover 2 forms a wall-attached air flow path 211. When the consumer's hair is close to or located within the wall-attached air flow path 211, the hair automatically and quickly wraps around the outer wall of the tube cover 2 to achieve a curling operation.

[0087] When multiple hairs need to be curled and fixed for a long time, the clamping member 3 can be clamped on the tube cover 2 with the hair wrapped around it to fix the hair and the tube cover 2. Then, the protruding ring 23 of the tube cover 2 can be pulled out from the connecting groove 14 in the inner tube 1, so that the tube cover 2 can be hung alone on the customer's hair for long-term curling and shaping. At the same time, another tube cover 2 can be connected to the inner tube 1 to perform the curling operation on more hairs simultaneously.

[0088] When consumers need to shape curly hair with different degrees of curl, they can select the tube cover 2 of appropriate diameter according to their needs, and plug and fix the convex ring 23 of the tube cover 2 with the corresponding connecting groove 14 and perform the curling operation, thereby achieving curly hair effects with different degrees of curl, which is simple and convenient.

[0089] The innovation of the present invention lies in that by connecting the inner tube and the tube cover to the air outlet end of the hair dryer, the airflow of the hair dryer can drive the hair to automatically and quickly wrap around the tube cover to achieve a quick curling operation, which saves time and effort and is convenient for consumers to quickly curl their hair; at the same time, the boss of the inner tube is provided with a plurality of connecting grooves of different diameters, and the connecting grooves of different diameters are correspondingly connected to the tube covers of different diameters, so that consumers can use one inner tube with tube covers of various specifications to shape curling effects of different wave sizes. At the same time, the tube cover can be detached from the inner tube to reduce the load on the hair, and the curling process is simple and convenient, so that consumers have a good curling experience.
