[0002] A hair straightener is a common household appliance. It typically has two hinged clamping arms that can open or close relative to each other, and heating plates are located on opposite sides of each clamping arm. Hair is placed between the two clamping arms, and the clamping arms are closed so that the heating plates come into contact with the hair. The heating plates heat the hair, thus altering its shape and achieving a straight hair style. However, the high temperature of the heating plates can damage the hair to some extent.

[0003] Hair dryers are also a common household appliance that can blow out hot air. By using the hot air from a hair dryer to continuously heat the hair, and at the same time using a comb or fingers to pull the hair, you can also achieve a straight hair style without damaging the hair. However, this requires a certain level of technical training and consumes a lot of time and effort.

[0004] To overcome the shortcomings of hair straighteners and hair dryers in straightening hair, hair dryer straighteners have emerged in the prior art. Hair dryer straighteners can quickly achieve straight hair styling results without damaging the hair, combining the advantages of both hair straighteners and hair dryers.

[0032] Please see 8 and Figure 9The heating module 33 of this embodiment includes a plurality of individual heating elements 3301. Each individual heating element 3301 is arranged in at least one of the following ways: side by side, stacked, connected end to end, or staggered, to form the heating module 33.

[0033] Specifically, for any single heating element 3301, it includes a heating element body 3302 and a heating element bracket 3307. The heating element bracket 3307 is fixedly connected to the heating element body 3302 to support the heating element body 3302 on the structure.

[0034] It should be noted that the structure is suitable for fixing a heating module 33 consisting of two or more individual heating elements 3301, for example, inside the outer casing of a household appliance, at the structural support of the household appliance, or in the air duct of the household appliance.

[0035] More specifically, the heater body 3302 includes a winding bracket 3303 and a heating wire 3306 wound on the winding bracket 3303; wherein, the winding bracket 3303 is a long strip-shaped metal bracket, and the heating wire 3306 is an enameled resistance wire heating wire 3306. Alternatively, the winding bracket 3303 can also be a heat-resistant engineering plastic bracket, and the heating wire 3306 can be an enameled resistance wire heating wire 3306 or an exposed resistance wire heating wire 3306; the heater bracket 3307 is fixedly connected to the winding bracket 3303 of the heater body 3302.

[0036] Please see Figure 2 More specifically, the winding bracket 3303 of the heater body 3302 has two parallel connecting arms 3304 at its end. In fact, the connecting arms 3304 are integrally formed extensions at the end of the winding bracket 3303, and the two connecting arms 3304 form a clamp-like shape. Each connecting arm 3304 has a first connecting hole 3305. The heater bracket 3307 is a heat-resistant engineering plastic component, including a bracket wall 3308 and a connecting frame 3311 connected to the bracket wall 3308. A second connecting hole 3312 is provided on 3311. In this embodiment, the support wall 3308 of the heater bracket 3307 has two sides and forms an L-shape. The connecting bracket 3311 is integrally formed on the inner side of the corner of the support wall 3308. The connecting bracket 3311 of the heater bracket 3307 is inserted between the two connecting arms 3304 of the heater body 3302 (the two are interference fit). Furthermore, the first connecting hole 3305 of the heater body 3302 and the second connecting hole 3312 of the heater bracket 3307 are aligned with each other so that screws or other connecting parts can pass through.

[0037] Furthermore, both ends of the heater body 3302 are provided with heater brackets 3307 to support both ends of the heater body 3302.

[0038] Furthermore, for any single heater 3301, the support wall 3308 of the heater bracket 3307 is adapted to abut against and be fixedly connected to the support wall 3308 of the heater bracket 3307 of another single heater 3301, so that at least two single heaters 3301 are adapted to form a heater module 33 in at least one of the following arrangements: side by side, stacked, and end to end.

[0039] In this embodiment, two individual heaters 3301 are provided. The support walls 3308 of the heater brackets 3307 of the two individual heaters 3301 abut against each other, so that the two individual heaters 3301 are arranged side by side. In this embodiment, a buckle 3309 is formed at the support wall 3308 of the heater bracket 3307 of one individual heater 3301, and correspondingly, a buckle groove 3310 is formed at the support wall 3308 of the heater bracket 3307 of the other individual heater 3301, thereby fastening the heater brackets 3307 of the two individual heaters 3301 into one piece.

[0040] Furthermore, an elastic pad 3313 is attached to one side of the connecting arm 3304 of the heater body 3302. The elastic pad 3313 is a square elastic rubber or elastic silicone material component, which is directly attached to the surface of the connecting arm 3304 of the heater body 3302 to buffer and insulate the heater body 3302.

[0041] In this embodiment, after the screw passes through the first connecting hole 3305 of the heater body 3302 and the second connecting hole 3312 of the heater bracket 3307 in sequence, it is locked into the screw post of the air duct shell component 32, thereby fixing the two individual heaters 3301. The elastic pad 3313 is disposed between the connecting arm 3304 of the air duct shell component 32 and the heater body 3302. In addition, the surface of the heater module 33 is covered with mica sheet, which is beneficial for heat insulation and avoids the heat of the heater module 33 from damaging the air duct shell component 32 and the air duct shell cover component 34.

[0042] Furthermore, the air outlet 341 on the air duct shell cover member 34 is strip-shaped and is provided along the extension direction of the clamp arm air duct 30.

[0043] Since the inner cavity of the air duct shell component 32 is roughly strip-shaped, the clamping air duct 30 it defines is also roughly strip-shaped. Therefore, by setting the heater module 33 to be strip-shaped and arranged along the extension direction of the clamping air duct 30, the space of the clamping air duct 30 can be fully utilized, and the airflow in the clamping air duct 30 can be fully heated by the heater module 33. At the same time, by setting the air outlet 341 on the air duct shell cover component 34 to be strip-shaped and arranged along the extension direction of the clamping air duct 30, the space of the clamping air duct 30 can be utilized as much as possible for air intake and exhaust. This not only expands the air outlet area of ​​the air outlet 341, but also makes the air pressure in each part of the air outlet 341 as even as possible.

[0044] Furthermore, an air guide ramp 322 is provided in the inner cavity of the air duct shell component 32, so that the clamp arm air duct 30 gradually narrows in the direction away from the air inlet port 321. In this embodiment, one side of the outer wall of the air duct shell component 32 is sloping, which serves as both the outer wall of the air duct shell component 32 and the air guide ramp 322. Setting the clamp arm air duct 30 to gradually narrow in the direction away from the air inlet port 321 can make the air pressure in each part of the clamp arm air duct 30 as even as possible.

[0045] Furthermore, the clamping arm assembly 3 has a sub-shell component 35 fixedly provided on the inner side of the main shell component 31 (specifically located on the lower side of the air duct shell component 32). The sub-shell component 35 is a cover plate made of engineering plastic, and a plurality of comb teeth 351 are integrally formed on the sub-shell component 35; in this way, the hair dryer straightener of this embodiment is provided with a combing function.

[0046] Please see Figures 3-5 Specifically, the fan assembly 2 includes a fan body 21 and an air outlet duct 23. The fan body 21 is a high-speed DC fan powered by DC electricity, and its outer contour is approximately cylindrical. The air outlet duct 23 is flexible; specifically, the air outlet duct 23 is made of flexible silicone, rubber, or plastic material, allowing it to deform. The air outlet duct 23 includes a main pipe section 231 and at least two branch pipe sections 232 branching from the main pipe section 231. Both the main pipe section 231 and the branch pipe sections 232 are integrally formed. In this embodiment... The branch pipe section 232 is configured as two paths, corresponding to two clamping arm assemblies 3 respectively. The main pipe section 231 of the air outlet duct 23 forms the main pipe duct 10, and each branch pipe section 232 of the air outlet duct 23 forms a branch pipe duct 20 respectively. The air outlet end of the fan body 21 is connected to the main pipe section 231 of the air outlet duct 23, and the branch pipe section 232 of the air outlet duct 23 is connected to the main shell component 31 of the clamping arm assembly 3 and connected to the air inlet port 321 of the air duct shell component 32. In this way, the connection between the branch pipe duct 20 of the fan assembly 2 and the clamping arm duct 30 of the clamping arm assembly 3 is realized.

[0047] Furthermore, the fan assembly 2 also includes a connecting flange 22 and a clamping ring 24. The connecting flange 22 is a short cylindrical tube made of metal or engineering plastic, and the clamping ring 24 is an elastic ring, for example, made of silicone rubber. The connecting flange 22 is fixedly installed at the air outlet end of the fan body 21. In fact, the connecting flange 22 can be integrated into the air outlet structure of the fan body 21, or it can be used as an independent component and fastened to the air outlet end of the fan body 21. The outer ring surface of the connecting flange 22 has a main ring groove 221, which is integrally formed with the connecting flange 22. The inner ring of the main pipe section 231 of the air outlet duct 23 is also formed by this groove. The fan body 21 has a main ring rib 233, which is integrally formed with the air outlet duct 23. The main pipe section 231 of the air outlet duct 23 is fitted onto the connecting flange 22, so that the main ring rib 233 of the air outlet duct 23 is engaged in the main ring groove 221 of the connecting flange 22. The outer ring surface of the main pipe section 231 of the air outlet duct 23 has a groove 235 at the position corresponding to the main ring rib 233. The groove 235 is integrally formed with the air outlet duct 23. The clamping ring 24 is fitted into the groove 235 to press the main ring rib 233 of the air outlet duct 23 into the main ring groove 221 of the connecting flange 22. In this way, the airtight connection between the fan body 21 and the air outlet duct 23 can be achieved.

[0048] Furthermore, a secondary ring rib 222 is formed on the outer ring surface of the connecting flange 22. In this embodiment, the secondary ring rib 222 is integrally formed with the connecting flange 22 and is located at a position further outward of the main ring groove 221. A secondary ring groove 234 is formed on the inner ring surface of the main pipe section 231 of the air outlet duct 23. In this embodiment, the secondary ring groove 234 is integrally formed with the air outlet duct 23 and is located at a position further inward of the main ring rib 233. The secondary ring rib 222 of the connecting flange 22 is engaged in the secondary ring groove 234 of the air outlet duct 23 to further improve the airtightness between the fan body 21 and the air outlet duct 23.

[0049] More specifically, the fan assembly 2 also includes a return hinge 25 and a pipe fitting frame 26. The return hinge 25 is a hinge assembly with a torsion spring, capable of expanding and returning to its original position (i.e., after compression, it can automatically return to its original position under the action of the torsion spring). It has two halves. The pipe fitting frame 26 is a bracket made of engineering plastic or metal, with a square frame as its main body and a pivot on one side. Two pipe fitting frames 26 are provided, each pivotally connected to one of the two halves of the return hinge 25. In fact, the pivot of the pipe fitting frame 26 is inserted into the pivot seat of the return hinge 25, thus pivotally connecting the pipe fitting frame 26 to the return hinge 25. For each pipe fitting frame... Frame 26: It is also fitted onto the outlet end of the branch pipe portion 232 of the air outlet duct 23 and fixed to the air duct shell component 32 of the clamping arm assembly 3 (specifically, fixed with screws) to press the outlet end of the branch pipe portion 232 of the air outlet duct 23 onto the air inlet port 321 of the air duct shell component 32 (specifically, the locking edge at the outlet end of the branch pipe portion 232 is pressed onto the outer periphery of the air inlet port 321 of the air duct shell component 32, so that the outlet end of the branch pipe portion 232 covers the entire air inlet port 321); in this way, the air duct connection between the air outlet duct 23 and the clamping arm assembly 3 is specifically realized, and after the clamping arm assembly 3 is closed, it can automatically return to its original position and open under the action of the return hinge 25.

[0050] Specifically, the main body shell assembly 1 includes a fan support component 11, an air inlet filter 12, a cover component 13, and an air inlet cover 15.

[0053] In this embodiment, the hair dryer / straightener starts operating after the blower body 21 of the blower assembly 2 and the heating element module 33 of the clamping arm assembly 3 are activated. When the blower body 21 is running, outside air passes sequentially through the air inlet cover 15, the air inlet filter 12, and the air inlet grille 113 of the blower bracket assembly 11, enters the air inlet section 112 of the blower bracket assembly 11, and is drawn into the blower body 21. Air is discharged from the outlet end of the blower body 21, and the airflow sequentially enters the main pipe section 231 of the connecting flange 22 and the air outlet duct 23. At this time, the airflow enters the main pipe duct 10. Subsequently, the airflow is split in the branch pipe section 232 of the air outlet duct 23, and the airflow enters the branch pipe duct 20. After that, the airflow passes through the air inlet again. Port 321 enters the air duct shell component 32 of the clamping arm assembly 3. At this time, the airflow enters the clamping arm air duct 30. Driven by wind pressure and guided by the air guide slope 322, the airflow in the clamping arm air duct 30 passes through the heating module 33 and is heated. Finally, it is ejected in the form of a jet from the air outlet 341 of the air duct shell cover component 34. The hair is placed between the two clamping arm assemblies 3. The hot air ejected from the air outlet 341 heats the hair, causing a certain degree of modification. At the same time, the hair is clamped and pulled by the air duct shell cover component 34, and combed by the comb teeth 351 of the secondary shell component 35. Straight hair can be obtained simply and quickly, with low damage to the hair quality.

[0054] In this embodiment of the hair dryer and straightener, a main air duct 10 is formed at the fan assembly 2, and the main air duct 10 branches into branch air ducts 20.

After being heated by the heating module 33 in the clamp air duct 30, the air is sprayed out from the air outlet 341 of the clamp air duct 30 in the form of a jet. In this way, the hair dryer and straightener is provided with a reasonable, efficient, easy-to-manufacture and assemble air duct structure with low wind and heat loss. This makes the hair dryer and straightener have the advantages of good air output, high energy efficiency and low manufacturing cost, thus improving the user experience of the hair dryer and straightener.
