Description

Technical Field

[0001] This utility model relates to the technical field of household appliances and their components, specifically a curling iron accessory for handheld hot air outlet devices. Background Technology

[0002] Curling is a common hair styling method. In the process of curling hair, the hair is usually wrapped around a curling iron, and the heat of the curling iron changes the hair's shape (commonly known as "perming") to achieve a curly hairstyle.

[0003] One type of curling iron, also known as a "blow-dry curling iron," "hot air curling iron," or "hot air curling stick," is typically a hollow rod-shaped body with an air inlet at one end and several slit-like or elongated air outlets on its sides. It needs to be plugged into a hot air outlet device (such as a hair dryer or blow-drying stick). In use, the curling iron is plugged into the hot air outlet of the device, allowing hot air to be drawn in through the inlet and directed to the outlet. This allows the hot air to be ejected from the outlets, reshaping the hair wrapped around the curling iron (commonly known as "curling") to achieve a curled hairstyle.

[0004] The announcement texts of Chinese utility model patents, namely CN218682614U, entitled "A Curling Iron with Hot Airflow for Setting Hair", CN221785579U, entitled "A Curling Iron with Controllable Airflow Direction", and CN217408065U, entitled "A Curling Iron with High-Speed ​​Hair Dryer", all disclose the typical structures of the above-mentioned types of curling irons.

[0005] However, this type of curling iron still has some technical problems:

[0006] 1. In this type of curling iron, the direction of the air outlet is consistent with the direction of the curling iron body (i.e., the axial direction of the curling iron body), so that the air outlet direction of the curling iron is completely coincident with the radial direction of the curling iron body. The hot air jetted in the radial direction will form a regular cylindrical shape. In terms of curling styling ability and hair care performance, there are still shortcomings.

[0007] 2. This type of curling iron usually has a flat surface and fails to provide an auxiliary structure for the curling process.

[0008] In conclusion, how to provide a more structurally optimized curling iron accessory for handheld hot air outlet devices has become an urgent problem to be solved. Utility Model Content

[0019] In the above technical solution, the curling iron accessory of the present invention applied to the handheld hot air outlet device further includes an inner air inlet component; the inner air inlet component is fixed in the support base component and is used to introduce airflow into the inner air guide component.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The curling iron accessory of this utility model, applied to a handheld hot air outlet device, has its strip-shaped air outlet configured to be inclined in the axial direction of the outgoing air tube component, so that the airflow surrounds the outgoing air tube component in a spiral shape (instead of being thrown out in the radial direction).

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This embodiment provides a curling iron accessory for handheld hot air outlet devices, which can be used as an accessory on handheld hot air outlet devices (such as hair dryers or blow dryers) to achieve the function of curling hair.

[0028] Please see Figures 1-4 The curling iron accessory of this embodiment, which is applied to a handheld hot air outlet device, includes at least an external air duct component 1.

[0029] The external ventilation duct component 1 is an integrally injection-molded engineering plastic component.

[0030] The outgoing air duct component 1 has several air outlet channels 10 extending through its inner and outer sides in the circumferential direction, and the air outlet channels 10 are provided with strip-shaped air outlets 101 on the outer side of the outgoing air duct component 1.

[0031] To optimize the hydrodynamic performance of the curling iron accessory applied to the handheld hot air outlet device in this embodiment, and to provide more auxiliary functions during hair styling, the strip-shaped air outlet 101 is configured to be inclined to the axial direction of the outgoing air duct component 1. Furthermore, the outgoing air duct component 1 is provided with a plurality of air guiding-combing composite teeth 13 at each strip-shaped air outlet 101. In fact, the air guiding-combing composite teeth 13 are comb-shaped structural features integrally formed on the surface of the outgoing air duct component 1, and the air guiding-combing composite teeth 13 are configured to be inclined to the radial direction of the outgoing air duct component 1.

[0032] Specifically, the outdoor ventilation duct component 1 includes an outer base plate 11 and a plurality of peripheral flaps 12 formed on the outer base plate 11 and extending in the axial direction; wherein, the outer base plate 11 has a circular plate-like structure and is used to provide a structural support foundation for the outdoor ventilation duct component 1, and the peripheral flaps 12 have a curved plate-like structure and are used to provide a functional support foundation for the outdoor ventilation duct component 1; each peripheral flap 12 is surrounded in the circumferential direction to form a cylindrical structure, which constitutes the basic shape of the outdoor ventilation duct component 1; there is a gap between each pair of adjacent peripheral flaps 12, which is the air outlet channel 10; the air guide-hair combing composite teeth 13 are connected between adjacent pairs of peripheral flaps 12, that is, the two ends of the air guide-hair combing composite teeth 13 are respectively connected to the two adjacent peripheral flaps 12.

[0033] Furthermore, the outer flap 12 of the outgoing air duct component 1 has a curved inner wall to form a curved air guide wall 102 in the air outlet channel 10, so that when the airflow passes through the air outlet channel 10, it is guided by the curved air guide wall 102 into a curved airflow.

[0034] Furthermore, the air guide-combing composite teeth 13 are evenly distributed along the extension direction of the strip-shaped air outlet 101.

[0035] Furthermore, the curling iron accessory for handheld hot air outlet devices in this embodiment also includes an inner air guide tube component 2, which is an integrally injection-molded engineering plastic component. The inner air guide tube component 2 includes an inner bottom plate 21 and a plurality of inner enclosing petals 22 formed on the inner bottom plate 21 and extending in the axial direction. The inner bottom plate 21 has a circular plate-like structure and provides a structural support foundation for the inner air outlet component. The inner enclosing petals 22 have a plate-like structure and provide a functional support foundation for the inner air outlet component. Each inner enclosing petal 22 encloses the inner air outlet component in the circumferential direction to form a cylindrical structure, thus constituting the inner air outlet component. The basic shape of the component is as follows: there is a gap between each pair of adjacent inner circumferential petals 22; the inner air guide duct component 2 also includes a number of inner air guide teeth 23 spanning between the two adjacent inner circumferential petals 22. In fact, the inner air guide teeth 23 are tooth-shaped structural features integrally formed on the surface of the inner air outlet duct component, and their two ends are respectively connected to the two adjacent inner circumferential petals 22. There is a gap between each pair of adjacent inner air guide teeth 23, which is the air guide gap 231; the inner air guide duct component 2 is inserted and fixed in the outer air outlet duct component 1, so that the inner air guide teeth 23 of the inner air guide duct component 2 are located in the air outlet channel 10 of the outer air outlet duct component 1.

[0036] More specifically, the inner bottom plate 21 of the inner air duct component 2 is fixed to the outer bottom plate 11 of the outer air duct component 1 by means of snap-fit ​​or interference fit; in this embodiment, the inner bottom plate 21 of the inner air duct component 2 is configured in a petal shape, and a groove matching the shape of the inner bottom plate 21 of the outer air duct component 1 is formed at the outer bottom plate 11 of the outer air duct component 1. The inner bottom plate 21 of the inner air duct component 2 is embedded in the groove of the outer bottom plate 11 of the outer air duct component 1 to achieve mutual fixation between the inner air duct component 2 and the outer air duct component.

[0037] Furthermore, the inner guide teeth 23 of the inner air guide duct component 2 abut against the inner wall of the outer air guide duct component 1, making the mechanical connection between the inner air guide duct component 2 and the outer air guide duct component tighter.

[0038] Furthermore, the inner circumferential flap 22 of the inner air guide duct component 2 forms an air guide slope 221 at the inlet of the air outlet channel 10 of the outer air guide duct component 1 in the direction of guiding the airflow into the air outlet channel 10, making it easier for the airflow in the inner air guide duct component 2 to be guided into the air outlet channel 10 of the outer air guide duct component 1.

[0039] Furthermore, the curling iron accessory applied to the handheld hot air outlet device in this embodiment also includes a support base component 3, which is a frustum-shaped component made of engineering plastic material integrally injection molded; the outer bottom plate 11 of the outgoing air duct component 1 is fixed to the support base component 3 by means of snap-fit ​​or interference fit; in this embodiment, the outer bottom plate 11 of the outgoing air duct component 1 is snapped to the support base component 3, and the outgoing air duct component 1 and the support base component 3 are airtightly fitted; the support base component 3 is suitable for being fixed to the air outlet of the handheld hot air outlet device by means of sleeve, plug, or snap-fit.

[0040] Furthermore, the curling iron accessory applied to the handheld hot air outlet device in this embodiment also includes an inner air inlet component 4, which is an integrally injection-molded cylindrical component made of engineering plastic. The inner air inlet component 4 is fixed in the support base component 3 and is used to introduce airflow into the inner air guide component 2. In this embodiment, the inner air inlet component 4 is fixed in the support base component 3 by screws or clips. In this embodiment, the inner air inlet component 4 has a large end and a small end that is narrower relative to the large end. The large end of the inner air inlet component 4 faces the air outlet of the handheld hot air outlet device to collect airflow, and the small end of the inner air inlet component 4 faces the inner air guide component 2 to guide the collected airflow into the inner air guide component 2.

[0041] In this embodiment, the hair curler accessory applied to a handheld hot air outlet device is used by fixing the support base component 3 to the air outlet of the handheld hot air outlet device through a sleeve, plug, or snap-fit ​​method, so that the entire hair curler accessory is connected to the handheld hot air outlet device as one unit. At this time, the user needs to wrap their hair around the surface of the external air tube component 1. When the handheld hot air outlet device is running, its air outlet jets out a high-temperature airflow, which is collected by the large end of the inner air inlet component 4 and guided into the inner air guide. The airflow enters the inner air guide duct component 2 and flows along the axial direction of the inner air guide duct component 2. It is guided by the guide slope 221 of the inner air guide duct component 2 and enters the outlet air passage 10 of the outer air guide duct component 1 through the guide gap 231 between each inner guide tooth 23. During this process, the guide gap 231 of the inner air guide duct component 2 helps to straighten the airflow entering the outlet air passage 10. After the airflow enters the outlet air passage 10 of the outer air guide duct component 1, it is guided by the curved guide wall 102 of the outlet air passage 10, forming a curved airflow. The airflow flows out from the strip-shaped air outlet 101 of the air outlet channel 10. At this time, the high-temperature airflow, combined with the surface temperature of the heated exhaust fan component 1, can modify the hair wrapped around the surface of the exhaust fan component 1 (i.e., the so-called "curling"), thereby obtaining a curly hairstyle. In the above process, firstly, because the strip-shaped air outlet 101 is inclined in the axial direction of the exhaust fan component 1, and secondly, because the airflow is guided into a curved shape by the curved air guide wall 102, the airflow from the strip-shaped air outlet 101 of the air outlet channel 10 flows out. The outflowing airflow forms a spiral shape around the outflowing air duct component 1 (instead of being ejected radially). This spiral airflow around the outflowing air duct component 1 can stay on the hair surface for a longer time and exchange heat with a larger area of ​​hair, resulting in a better curling effect compared to existing hair dryer curling irons. In the above process, the air guide-combing composite teeth 13 play a role in separating and straightening the hair to prevent excessive hair accumulation and uneven heating. They also help to straighten the airflow ejected from the strip-shaped air outlet 101.

[0042] The curling iron accessory of this embodiment, applied to a handheld hot air outlet device, has a strip-shaped air outlet 101 configured to be inclined in the axial direction of the outgoing air tube component 1, so that the airflow surrounds the outgoing air tube component 1 in a spiral shape (instead of being thrown out in the radial direction). The spiral airflow surrounding the outgoing air tube component 1 can stay on the hair surface for a longer time and exchange heat with a larger area of ​​hair, resulting in a better curling effect than existing hair dryer curling irons. Its air guide-combing compound teeth 13 play a role in separating and straightening the hair to prevent excessive hair gathering and uneven heating, and also help to straighten the airflow jetting out from the strip-shaped air outlet 101. In summary, the curling iron accessory of this embodiment applied to a handheld hot air outlet device has a more reasonable and efficient hydrodynamic structure and mechanical auxiliary structure, which can achieve better curling ability and hair care performance.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
