Technical Field
[0001] This utility model relates to the field of hair styling accessories technology, and in particular to a curved tube assembly and hair styling device for hair styling accessories. Background Technology
[0002] In related technologies, hair styling devices are equipped with hair styling attachments to assist users in drying or styling hair. Currently, both the hair styling device and its attachments extend axially. After assembly, they are on the same axis, requiring users to raise their arms to align the attachments perpendicular to their hair, making it very strenuous and significantly reducing its convenience.
[0003] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content
[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a curved tube assembly for hair styling accessories, effectively solving the technical defect that hair styling accessories in the existing technology are very laborious to use, thereby improving the convenience of use for users.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a curved tube assembly for hair styling accessories, comprising...
[0006] The attachment includes a first air inlet and a first air outlet; and,
[0007] The bend assembly has an air supply duct;
[0008] The bend assembly includes an outer bend, an inner bend that can be movably installed inside the outer bend, and a connector fixedly installed at one end of the inner bend; an accessory is installed at the other end of the inner bend, and the accessory, together with the connector, can clamp the outer bend and connect the first air inlet to the air supply duct.
[0009] The beneficial effect of the curved tube assembly for hair accessories provided in this application is that, compared with the prior art,
[0010] Firstly, the attachment can be installed on the hair styling device via the curved tube assembly, so that the attachment and the hair styling device are set at an angle. When styling hair, users do not need to raise their arms to keep the attachment perpendicular to the hair; this reduces the difficulty of styling hair, saves time and effort, and thus improves the user's ease of use.
[0011] Secondly, by using accessories and connectors to clamp the outer bend, there is no need to insert into the inner bend to fix it during assembly, thus reducing assembly difficulty and improving assembly convenience and efficiency. At the same time, it can reduce the existence of assembly lines, so that there is only one assembly line between the bend assembly and the accessories, and only one assembly line between the outer bend and the connector. The outer bend as a whole has no assembly lines or decorative lines, thereby improving the flatness of the overall appearance of the bend assembly and enhancing its overall aesthetics.
[0012] As a preferred embodiment, the inner bend extends along the first arc-shaped trajectory line, and the outer bend extends along the second arc-shaped trajectory line, with the arc of the first arc-shaped trajectory line being the same as that of the second arc-shaped trajectory line.
[0013] Compared with existing technologies, by setting the arc trajectory lines of the inner and outer bends to the same curvature, the inner bend can be directly pushed into the outer bend along its arc trajectory line during the process of inserting the inner bend into the outer bend.
[0014] As a preferred option, the externally bent tube is integrally stamped from metal or integrally injection molded from plastic.
[0015] Compared with existing technologies, the one-piece molded outer bend tube can achieve a higher overall flatness on the outer surface, eliminating assembly seams or decorative lines, thereby improving the overall aesthetic appearance of the bend tube assembly.
[0016] As a preferred option, both the inner and outer bends have circular cross-sections, with the inner bend having a smaller diameter than the outer bend.
[0017] As a preferred embodiment, the outer surface of the inner bend is provided with an axial rib, which can abut against the inner wall of the outer bend; or,
[0018] The outer surface of the inner bend is provided with axial and circumferential ribs, which can abut against the inner wall of the outer bend.
[0019] Compared with existing technologies, the axial and circumferential ribs allow for two main advantages: First, different diameter inner bends can be configured according to actual usage needs, and the axial and circumferential ribs abut against the inner wall of the outer bend, resulting in a firmly assembled and stable bend assembly. Second, the axial and circumferential ribs insulate the inner bend, preventing heat from the hot air flowing through it from being transferred to the outer bend. This not only improves the insulation effect but also reduces the risk of burns for users.
[0020] As a preferred embodiment, a limiting protrusion is provided at the end of the axial bone position opposite to the inner bend tube, and a limiting groove is provided on the inner wall surface of the outer bend tube;
[0021] After the inner bend is inserted into the outer bend, the limiting protrusion can be inserted into the limiting groove.
[0022] As a preferred embodiment, the connector has a first mounting recess on its top periphery and a first mounting protrusion at one end of the outer bend.
[0023] When the connector is installed at one end of the inner bend, the first mounting protrusion can abut against the first mounting recess, so that the outer surface of the outer bend and the outer surface of the connector are smoothly transitioned.
[0024] As a preferred embodiment, the inner bend has a first locking position at one end and a second locking position at the other end;
[0025] The connector has a third locking position that matches the first locking position, and the accessory has a fourth locking position that matches the second locking position.
[0026] As a preferred embodiment, the connector is provided with a snap-fit structure for snapping into connection with the hair styling device.
[0027] This application also provides a hair styling device, including a handle, one end of which is detachably fitted with a curved tube assembly for hair styling accessories, such that the accessories are set at an angle to the handle.
[0028] The handle has a second air inlet and a second air outlet. When the connector is connected to the hair styling device, the second air outlet is connected to the air supply duct.
[0029] Compared with existing technologies, by installing the attachment onto the curved tube assembly, and then onto the hair styling device via the curved tube assembly, the attachment and the hair styling device can be set at an angle. This allows users to keep the attachment perpendicular to the hair without raising their arms when styling hair. This reduces the difficulty of hair styling for users, saves time and effort, and improves the user's convenience. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0047] Please refer to the following: Figures 1 to 6 The curved tube assembly 10 for hair styling accessories provided in this application embodiment will now be described. The curved tube assembly 10 for hair styling accessories 20 includes: a curved tube assembly 10 and an accessory 20.
[0048] The pipe bending assembly 10 includes an outer bend 11, an inner bend 12 that can be movably installed inside the outer bend 11, and a connector 13 fixedly installed at one end of the inner bend 12. The inner bend 12 has an air supply duct 101. The accessory 20 has a first air inlet 201 and a first air outlet 202. The accessory 20 is installed at the other end of the inner bend 12. The accessory 20 and the connector 13 can clamp the outer bend 11 together and make the first air inlet 201 connected to the air supply duct 101.
[0049] Specifically, through the outer curved tube 11, inner curved tube 12, and connector 13, firstly, the accessory 20 can be installed on the hair styling device 30 via the curved tube assembly 10, so that the accessory 20 and the hair styling device 30 are set at an angle. When the user styles hair, the accessory 20 can be kept perpendicular to the hair without raising the arm. This reduces the difficulty of hair styling for the user, saves time and effort, and improves the user's ease of use. Secondly, by using the accessory 20 and connector 13 to clamp the outer curved tube 11 together, it is not necessary to insert into the outer curved tube 11 to fix the inner curved tube 12 during the assembly process, thereby reducing the assembly difficulty and improving the assembly convenience and efficiency.
[0050] It should be noted that Attachment 20 is a hair styling accessory 20 that assists users in drying or styling their hair. Attachment 20 can be any of the following: curling iron, nozzle, comb, or heated hair straightener.
[0051] In some embodiments, the inner bend 12 extends along a first arcuate trajectory line r1, and the outer bend 11 extends along a second arcuate trajectory line r2. The curvature of the first arcuate trajectory line r1 is the same as that of the second arcuate trajectory line r2. By setting the arcuate trajectories of the inner bend 12 and the outer bend 11 to have the same curvature, the inner bend 12 can be directly pushed into the outer bend 11 along its arcuate trajectory line during the insertion process. This simplifies the assembly process and eliminates the need to insert the inner bend 12 into the outer bend 11 for fixation.
[0052] It should be noted that the first extension length of the inner bend 12 along the first arc-shaped trajectory line is less than the second extension length of the outer bend 11 along the second arc-shaped trajectory line; or, the first extension length of the inner bend 12 along the first arc-shaped trajectory line is equal to the second extension length of the outer bend 11 along the second arc-shaped trajectory line; that is to say, the length dimension of the inner bend 12 is less than or equal to the length dimension of the outer bend 11.
[0053] Specifically, the outer bend 11 is integrally stamped from metal or integrally injection molded from plastic. Both the inner bend 12 and the outer bend 11 have circular cross-sections, with the inner bend 12 having a smaller diameter than the outer bend 11. The outer surface of the inner bend 12 is provided with an axial rib 121, which abuts against the inner wall of the outer bend 11; or, the outer surface of the inner bend 12 is provided with both an axial rib 121 and a circumferential rib 122, which abut against the inner wall of the outer bend 11.
[0054] It should be noted that the axial bone position 121 extends along the extension direction of the first arc-shaped trajectory line, and the circumferential bone position 122 extends circumferentially along the outer surface of the inner curved tube 12.
[0055] More specifically, by setting the structure of axial rib 121 and circumferential rib 122, firstly, different diameter inner bends 12 can be configured according to actual usage needs, and a firmly assembled and stable bend assembly 10 can be obtained by the axial rib 121 and circumferential rib 122 abutting against the inner wall of the outer bend 11; secondly, the axial rib 121 and circumferential rib 122 can insulate the inner bend 12 to prevent the heat of the hot air flowing through the inner bend 12 from being transferred to the outer bend 11; this not only improves the heat insulation effect but also ensures that users are less likely to be burned during use; thirdly, the axial rib 121 and circumferential rib 122 can support the outer bend 11, ensuring the overall strength of the outer bend 11 even when the wall thickness of the outer bend 11 is relatively thin, and preventing it from being dented due to external forces.
[0056] In other embodiments, the axial bone position 121 has a limiting protrusion 123 at the end opposite to the inner bend 12, and a limiting groove 111 is provided on the inner wall surface of the outer bend 11. When the inner bend 12 is inserted into the outer bend 11, the limiting protrusion 123 can be inserted into the limiting groove 111. By inserting the limiting protrusion 123 into the limiting groove 111, the assembly reliability of the inner bend 12 and the outer bend 11 can be improved. On the other hand, it can prevent the outer bend 11 from rotating relative to the inner bend 12 after the inner bend 12 is inserted into the outer bend 11, thereby further improving the assembly reliability and assembly stability of the inner bend 12 and the outer bend 11.
[0057] Specifically, the connector 13 has a first mounting recess 131 on its top periphery, and the outer bend 11 has a first mounting protrusion 112 at one end. When the connector 13 is installed on one end of the inner bend 12, the first mounting protrusion 112 can abut against the first mounting recess 131, so that the outer surface of the outer bend 11 and the outer surface of the connector 13 are smoothly transitioned. The other end of the outer bend 11 abuts against one end of the accessory 20, and the outer surface of the outer bend 11 and the outer surface of one end of the accessory 20 are smoothly transitioned, so that there is only one assembly line between the bend assembly 10 and the accessory 20, and only one assembly line between the outer bend 11 and the connector 13. The outer bend 11 as a whole does not have any assembly lines or decorative lines, thereby improving the flatness of the overall appearance of the bend assembly 10 and thus improving the overall aesthetics of the bend assembly 10.
[0058] In some embodiments, the inner bend 12 has a first locking position 124 at one end and a second locking position 125 at the other end; the connector 13 has a third locking position 132 that is adapted to the first locking position 124, and the accessory 20 has a fourth locking position 21 that is adapted to the second locking position 125.
[0059] Specifically, the first locking position 124 is the first screw hole, and the third locking position 132 is the first countersunk hole adapted to the first screw hole. By screwing the screw through the first countersunk hole and connecting it to the first screw hole, the fixed installation of the connector 13 and the inner bend tube 12 can be completed. The second locking position 125 is the second countersunk hole, and the third locking position 132 is the second screw hole. By screwing the screw through the second countersunk hole and connecting it to the second screw hole, the fixed installation of the accessory 20 and the inner bend tube 12 can be completed.
[0060] It should be noted that the assembly between the inner bend 12 and the first connector 13 and accessory 20 can also be secured using the snap-fit structure 133, adhesive, or welding. Furthermore, the first locking position 124, the second locking position 125, the third locking position 132, and the fourth locking position 21 can all be threaded holes; by passing screws through the corresponding threaded holes, the locking installation between the two components can also be completed.
[0061] In other embodiments, a hair styling device 30 is also included. The hair styling device 30 has at least a handle portion 31. One end of the handle portion 31 is detachably mounted with a curved tube assembly 10 for a hair styling accessory 20, so that the accessory 20 can be set at an angle to the handle portion 31. This angle is defined as a first angle, which is between 0 degrees and 120 degrees. By mounting the accessory 20 to the curved tube assembly 10 and then mounting it to the hair styling device 30 via the curved tube assembly 10, the accessory 20 can be set at an angle to the hair styling device 30. This allows the user to keep the accessory 20 perpendicular to the hair without raising their arm when styling hair. This reduces the difficulty of hair styling for the user, saves time and effort, and improves the user's ease of use.
[0062] Specifically, the connector 13 is provided with a fastening structure 133, which is used to fasten and connect with the hair styling device 30. The fastening structure 133 is a fastening recess recessed into the outer surface of the connector 13. One end of the handle portion 31 has a second air outlet, and the inner wall of the second air outlet 33 is provided with a fastening protrusion (not shown in the figure). When the connector 13 is installed in the second air outlet 33 of the handle portion 31, the fastening protrusion can be fastened into the fastening recess, so that the bent tube assembly 10 is fastened and assembled with the handle of the hair styling device 30.
[0063] More specifically, the inner bend tube 12 has an air supply duct 101, and a fan assembly is installed inside the handle part 31. The top of the handle part 31 is the second air outlet 33, and the bottom of the handle part 31 is the second air inlet 32. When the connector 13 is installed at the second air outlet 33 of the handle part 31, external air can be drawn in from the second air inlet 32 through the fan assembly and flow into the air supply duct 101 from the second air outlet 33. The air supply duct 101 then inputs the airflow from the first air inlet 201 into the accessory 20, and discharges it outward through the first air outlet 202 of the accessory 20. This allows the user to wrap hair around the surface of the accessory 20 and use the airflow discharged outward from the first air outlet 202 to assist the user in drying or styling the hair.
[0064] The assembly process of the curved tube assembly 10 for hair styling accessory 20 provided in this embodiment is described in detail below:
[0065] First, an inner bend 12 and accessory 20 are provided. One end of accessory 20 is fastened to the other end of inner bend 12 with screws.
[0066] Then, an outer bend 11 is provided, the outer bend 11 is placed at one end of the inner bend 12, and the inner bend 12 is inserted into the outer bend 11, such that one end of the outer bend 11 abuts against the accessory 20.
[0067] Finally, connector 13 is provided. Connector 13 is installed at one end of inner bend 12 and fastened to one end of inner bend 12 with screws. At the same time, outer bend 11 is clamped by accessory 20 and connector 13.
[0068] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
