Description

Technical Field

[0001] This invention relates to the field of hair care tools, and more particularly to a straightening comb with a steam function. Background Technology

[0002] Hair straighteners are widely used in the hair care industry to straighten hair. A typical hair straightener mainly consists of a heating element, comb teeth assembly, circuit board, and housing. Hair is straightened by passing through the heated metal comb teeth. However, these heated hair straighteners can easily burn hair due to their high temperature. To address this, hair straighteners with steam functions were invented. By incorporating a steam device into the hair straightener, steam is released to moisten the hair, thus preventing damage. A typical example is a steam comb head and steam hair straightener disclosed in CN215837524U, where the steam outlet is located near the side edge of the comb teeth. The hair passes through the heated metal comb teeth first and then through the steam outlet. This results in the hair passing through the high-temperature metal comb teeth (usually 180°C) and then through the lower-temperature steam (usually 120°C), or vice versa, causing uneven heating of the hair.

[0003] Another typical steam comb and steam straightener, such as the one disclosed in CN207803722U, is an automatic steam-generating straightener with steam outlets located between the comb teeth. This structure has two problems: First, the relatively large distance between the steam outlets and the comb teeth means the steam must first fill the gaps between the teeth before reaching their surface. This results in uneven heating of the hair, as mentioned earlier, due to the hair being exposed to high-temperature comb teeth followed by low-temperature steam (or vice versa). Second, the space between the comb teeth for the steam outlets inevitably affects the tooth density, leading to larger gaps. Excessive gaps cannot provide sufficient clamping force to the hair, significantly impacting the straightening effect. Furthermore, the large gaps between the teeth reduce the binding effect on the steam, causing it to dissipate quickly and remain between the teeth for a short time, thus affecting the effectiveness of the steam-driven hair straightening. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a steam comb and steam straightener with a more rational structural design, which allows steam to more easily reach the hair and produces less noise.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a device including a shell, a comb tooth assembly and a steam assembly, wherein the steam assembly includes a steam chamber and a heating element; a steam outlet is provided at the root position of several comb teeth of the comb tooth assembly, the steam outlet laterally penetrates the comb tooth and protrudes on the left and right sides of the comb tooth to connect the gap between adjacent comb teeth, and each steam outlet is connected to the steam chamber of the steam assembly.

[0006] Preferably, the comb assembly includes fixed comb teeth and movable comb teeth. The fixed comb teeth have a fixed base plate, and the movable comb teeth are movably mounted on the fixed base plate and close to the fixed comb teeth. The steam outlets are exposed on both sides of the movable comb teeth.

[0007] Furthermore, the movable comb teeth are elastic comb teeth, which are movably installed between the fixed comb teeth through elastic components; a vent hole penetrating the elastic comb tooth is provided at the lower part of the elastic comb tooth, and a support foot is provided at the bottom of the elastic comb tooth; an air inlet groove is provided vertically on the support foot, and an air distribution groove is provided horizontally on the bottom surface of the support foot; an air distribution hole is provided horizontally at the bottom of the fixed comb tooth, the air distribution hole is opposite to the vent hole, the vent hole is connected to the steam component through the air distribution hole and the air inlet groove, and the air distribution groove is also connected to the steam component, so that the gap between the elastic comb teeth and the gap between the elastic comb teeth and the fixed comb teeth are both connected to the steam component.

[0008] Furthermore, a guide cover is provided at the middle position of the bottom surface of the fixed base plate, and a number of guide nozzles are provided on the guide cover. Air guide holes are provided in the guide nozzles. The air inlet groove and the air distribution groove are connected to the steam assembly through the air guide holes.

[0009] Furthermore, heaters are respectively installed on the bottom surface of the fixed base plate at positions on both sides of the guide cover. The heaters and the guide cover are fastened to the bottom surface of the fixed base plate by a heater cover. The heater cover is provided with several connecting holes, through which the air guide hole is connected to the steam assembly.

[0010] Furthermore, the steam assembly is installed on the bottom surface of the heater cover and connects to each air inlet through the connecting hole of the heater cover.

[0011] Furthermore, the steam assembly also includes a steam cover and a sealing cover. The steam cover is sealed and pressed against the steam chamber with a sealing gasket. Several steam nozzles are provided on the steam cover, and nozzle sleeves corresponding to the number and position of the steam nozzles are provided on the sealing cover. The sealing cover is placed on the steam cover, and the nozzle sleeves are placed on the steam nozzles and inserted together into the connecting hole of the heater cover to align with the air inlet of the guide cover. The heating element is installed on the bottom surface of the steam chamber by a pressure plate. The steam assembly and the heating assembly are covered by a heat insulation box.

[0012] Alternatively, the movable comb teeth are oscillating comb teeth, which are movably mounted on the fixed base plate through a plug-in structure and spaced apart from the fixed comb teeth; multiple air outlets are provided in the fixed base plate, the air outlets are aligned with the bottom of each oscillating comb tooth and connected to the steam assembly; an air guide groove is provided at the bottom of the oscillating comb tooth, the air guide groove runs horizontally through the oscillating comb tooth, and the gap between the oscillating comb tooth and the fixed comb tooth is connected to the air outlet through the air guide groove.

[0013] Furthermore, heaters are respectively installed on the bottom surface of the fixed base plate at positions on both sides of the air outlet. The heaters are fastened to the bottom surface of the fixed base plate by a heater cover. The heater cover is provided with several connecting holes, which connect the air outlet to the steam assembly.

[0014] Furthermore, the steam assembly is installed on the bottom surface of the heater cover and connects to the air outlet of the fixed base plate through the connecting hole of the heater cover.

[0015] A steam straightening comb includes a comb head, a water tank assembly, a heating assembly, a water pump, and a circuit board. The steam assembly includes a steam chamber and a heating element, and the heating assembly includes a heater. The water pump, the heating element, and the heater are electrically connected to the circuit board. The steam chamber is connected to the water tank assembly via the water pump. The comb head is the aforementioned steam comb head, and the steam comb head and the main body of the steam straightening comb are combined to form a complete steam straightening comb.

[0016] This invention features a steam outlet at the base of the comb teeth. Steam exiting from this outlet flows along the surface of the comb teeth, creating a "Coanda effect" similar to the hair straightening process. This surrounds the hair with high-temperature steam the instant the hair is physically straightened by the comb teeth, forming a "gas-liquid two-phase heat exchange space." This space utilizes synergistic heating and moisture to simultaneously heat the hair, resulting in more even heating and higher styling efficiency compared to existing steam combs and straighteners that first pass through high-temperature comb teeth followed by low-temperature steam (or vice versa). Furthermore, since no space is needed for the steam outlet, the comb teeth can be arranged more densely, particularly suitable for close-proximity oscillating and fixed comb teeth, improving the straightening effect of the steam comb and straightener. The denser teeth and smaller gaps (e.g., 0.5-2mm, compared to approximately 3-10mm in traditional designs) enhance the steam's binding effect, allowing the steam to remain between the teeth for a longer period, providing prolonged moisture to the hair and thus improving the effectiveness of steam hair transplantation.

Detailed Implementation

[0036] Reference Figures 1-13 In the first embodiment, the steam straightening comb includes a steam comb head, a heating component 4, a water tank component 5, and a circuit board. The steam comb head includes a housing 1, a comb tooth component 2, and a steam component 3. The steam component 3 includes a steam chamber 31 and a heating element 34. The steam chamber 31 is connected to the water tank component 5 via a water pump 6. The heating component 4 includes a heater 41. The water pump 6, the heating element 34, and the heater 41 are electrically connected to the circuit board.

[0037] The comb assembly 2 includes a fixed comb tooth 21, a movable comb tooth, and a heat insulation sleeve. The fixed comb tooth 21 has a fixed base plate 23. The movable comb tooth is movably mounted on the fixed base plate 23 and close to the fixed comb tooth 21. The steam outlet is exposed on both sides of the movable comb tooth.

[0038] The movable comb teeth are elastic comb teeth 22, which are movably installed between the fixed comb teeth 21 via elastic components (the elastic comb tooth structure of this comb tooth assembly can be found in a straight hair comb with elastic floating comb teeth disclosed in patent CN222236957U); a vent hole 223 penetrating the elastic comb tooth 22 is provided at the lower part of the elastic comb tooth 22, and a support foot 221 is provided at the bottom of the elastic comb tooth 22; an air inlet groove 222 is provided vertically on the support foot 221, and an air distribution groove 224 is provided horizontally on the bottom surface of the support foot 221; an air distribution hole 211 is provided horizontally at the bottom of the fixed comb tooth 21, the air distribution hole 211 is opposite to and connected to the vent hole 223, the vent hole 223 is connected to the steam assembly 3 through the air distribution hole 211 and the air inlet groove 222, and the air distribution groove 224 is also connected to the steam assembly 3, so that the gap between the elastic comb teeth 22 and the gap between the elastic comb teeth 22 and the fixed comb teeth 21 are both connected to the steam assembly 3.

[0039] A guide cover 7 is provided at the middle position of the bottom surface of the fixed base plate 23. A number of guide nozzles 71 are provided on the guide cover 7. Air guide holes 72 are provided in the guide nozzles 71. The air inlet groove 222 and the air distribution groove 224 are connected to the steam component 3 through the air guide holes 72.

[0040] Heaters 41 are respectively provided on the bottom surface of the fixed base plate 23 at the positions on both sides of the guide cover 7. The heaters 41 and the guide cover 7 are fastened to the bottom surface of the fixed base plate 23 by a heater cover 42. The heater cover 42 is provided with several connecting holes 421, through which the air guide hole 72 is connected to the steam assembly 3.

[0041] The steam assembly 3 is installed on the bottom surface of the heater cover 42 and is connected to each air inlet 71 through the connecting hole 421 of the heater cover 42.

[0042] The steam assembly 3 also includes a steam cover 32 and a sealing cover 33. The steam cover 32 is sealed and pressed against the steam chamber 31 with a sealing gasket 36. Several steam nozzles 321 are provided on the steam cover 32. The sealing cover 33 is provided with nozzle sleeves 331 in number and position corresponding to the steam nozzles 321. The sealing cover 33 covers the steam cover 32, and the nozzle sleeves 331 are fitted onto the steam nozzles 321 and inserted together into the connecting hole 421 of the heater cover 42 to connect with the air inlet 71 of the guide cover 7. The heating element 34 is installed on the bottom surface of the steam chamber 31 through a pressure plate 35. The steam assembly 3 and the heating assembly 4 are covered by a heat insulation box.

[0043] like Figure 10 As indicated by the arrow, the steam generated in the steam chamber 31 enters the air guide hole 72 through the steam nozzle 321, and then splits into three paths. One path enters the air distribution hole 211 through the air inlet groove 222, and then flows out through the air distribution hole 211 into the gap between the fixed comb teeth 21 and the elastic comb teeth 22, and enters the gap between the elastic comb teeth 22 through the air vent 223; the other two paths enter the gap between the elastic comb teeth 22 through the air distribution groove 224 respectively. Since the steam flows out from the root of each comb tooth, it will follow the "Coanda effect" to a certain extent, that is, it first flows upward along the surface of the comb teeth, producing a steam enveloping effect.

[0044] Reference Figures 14-18 In the second embodiment, the movable comb teeth are oscillating comb teeth 24. The oscillating comb teeth 24 are movably mounted on the fixed base plate 23 through a plug-in structure and are spaced apart from the fixed comb teeth 21 (for the oscillating comb tooth structure of this comb tooth assembly, please refer to the adaptive heating comb tooth structure and straightening comb disclosed in patent application 2025226015774). A plurality of air outlets 231 are provided in the fixed base plate 23. The air outlets 231 are aligned with the bottom of each oscillating comb tooth 24 and are connected to the steam assembly 3. An air guide groove 241 is provided at the bottom of the oscillating comb tooth 24. The air guide groove 241 extends laterally through the oscillating comb tooth 24. The gap between the oscillating comb tooth 24 and the fixed comb tooth 21 is connected to the air outlet 231 through the air guide groove 241.

[0045] Heaters 41 are respectively installed on the bottom surface of the fixed base plate 23 on both sides of the air outlet 231. The heaters 41 are fastened to the bottom surface of the fixed base plate 23 by a heater cover 42. The heater cover 42 is provided with several connecting holes 421, through which the air outlet 231 is connected to the steam assembly 3.

[0046] The steam assembly 3 is installed on the bottom surface of the heater cover 42 and is connected to the air outlet 231 of the fixed base plate 23 through the connecting hole 421 of the heater cover 42.

[0047] In this embodiment, the steam generated in the steam chamber 31 enters the air outlet 231 of the fixed base plate 23 through the steam nozzle 321, and then flows out to both sides through the air guide groove 241 into the gap between the fixed comb teeth 21 and the oscillating comb teeth 24. Figure 16 As indicated by the arrow. Since the steam flows out from the root of each comb tooth, it follows the "Coanda effect" to some extent, that is, it first flows upward along the surface of the comb tooth. At the same time, because the steam stays longer between the denser comb teeth, it produces a better steam envelopment effect.

[0048] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
