Description

Technical Field

[0001] This invention relates to the technical field of hair styling tools, and in particular to an egg roll steam hair styling device. Background Technology

[0002] With the rapid development of the beauty and hairdressing industry, consumers' demands for the diversity and convenience of hair styling are increasing. Egg roll hair straighteners, as a type of hair styling tool that can quickly curl hair into egg roll (wave) shapes, are widely used in everyday home styling and professional hairdressing scenarios due to their simple operation and natural styling effects. The core working principle of existing egg roll hair straighteners is to heat a wave-shaped heating plate using a built-in heating element. The high temperature softens the hair cuticle, and then the wave structure of the heating plate sets the curl, ultimately creating an egg roll shape.

[0003] However, existing steam curling irons have the following shortcomings in actual use: During the high-temperature styling process, the cuticle softens while a large amount of moisture is lost. Long-term use can easily lead to dry, frizzy, split ends, and even breakage, especially for already dry and damaged hair. If the user uses the iron on hair that is not completely dry, the high temperature will cause the residual moisture inside the hair to vaporize and expand instantly, creating a "bubble hair effect," which damages the protein structure inside the hair and causes irreversible damage. In view of this, the steam curling iron hair styling iron of this application is proposed. Summary of the Invention

[0023] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0024] like Figures 1 to 17 As shown, in one embodiment, an egg roll steam hair stylist 1 includes a shell and a steam assembly. The shell includes a first shell 10 and a second shell 11, with one end of the first shell 10 and the second shell 11 hinged together. The steam assembly includes a first clamping plate 20, a second clamping plate 21, a steam element, and several heating plates. The first clamping plate 20 is disposed on the first shell 10, the second clamping plate 21 is disposed on the second shell 11, at least two heating plates are disposed on the first clamping plate 20, at least one heating plate is disposed on the second clamping plate 21, and the steam element is disposed on the first clamping plate 20, and the steam element and the first clamping plate 20 together clamp a heating plate. The first clamping plate 20 has at least one air outlet 220, and the air outlet 220 communicates with the steam element. The first shell 10 and the second shell 11 are brought closer together by external force to clamp the hair together, so that the steam in the steam element is sprayed into the gap between the first clamping plate 20 and the second clamping plate 21 through the air outlet 220.

[0025] It should be noted that one end of the first housing 10 and the second housing 11 are connected by a hinge; the first clamping plate 20 is disposed on the first housing 10, and the second clamping plate 21 is disposed on the second housing 11. Furthermore, both the first clamping plate 20 and the second clamping plate 21 have a corrugated structure (for example, the first clamping plate 20 and the second clamping plate 21 are mutually adaptable S-shaped structures, or continuously bent to tend towards a W-shaped structure). The first clamping plate 20 and the second clamping plate 21 are made of a metal material with high thermal conductivity (for example, the first clamping plate 20 and the second clamping plate 21 are aluminum plates or copper plates). When the first housing 10 and the second housing 11 are brought closer together by an external force, the first clamping plate 20 and the second clamping plate 21 are clamped together in a parallel state. When the first housing 10 and the second housing 11 are moved away from each other, the first clamping plate 20 and the second clamping plate 21 are respectively moved away from each other to an open state with an angle. Furthermore, since the first clamping plate 20 has an S-shaped structure, its side away from the second clamping plate 21 is divided into a bulge and a recess along the axial direction; the first clamping plate 20 is integrally formed with a first clamping groove 221 and a second clamping groove 222, with the first clamping groove 221 located in the bulge and the second clamping groove 222 located in the recess; the second clamping plate 21 is integrally formed with a third clamping groove 210; for ease of description, each heating plate is defined as a first heating plate 22, a second heating plate 23, and a third heating plate 24, respectively. The first heating plate 22 is disposed in the first clamping groove 221, the second heating plate 23 is disposed in the second clamping groove 222, and the third heating plate 24 is disposed in the third clamping groove 210; since the first clamping groove 221 and the second clamping groove 222 are distributed alternately, the heat generated by the first heating plate 22 and the second heating plate 23 can be evenly distributed on the first clamping plate 20, avoiding the heat from concentrating in a local position of the first heating plate 22, which would affect the hair styling effect. Furthermore, the steam element is mounted on the first clamping plate 20, and one side of the steam element and the inner wall of the mounting plate groove clamp the second heating plate 23 together, so that the heat of the second heating plate 23 can be conducted to the first clamping plate 20 and the steam element respectively. Furthermore, the first clamping plate 20 has multiple air outlets 220, each air outlet 220 having an oblong structure and being spaced apart in a straight line; one end of each air outlet 220 communicates with the side of the first clamping plate 20 closest to the second clamping plate 21, while the other end of each air outlet 220 communicates with the steam element; when the second heating plate 23 heats the steam element, the steam generated can be ejected through each air outlet 220 and enter the gap between the first clamping plate 20 and the second clamping plate 21. Furthermore, each air outlet 220 is located between the bulge and the recess (i.e., in the middle of the first clamping plate 20). Thus, when the first clamp 20 and the second clamp 21 clamp the hair together, the steam is ejected through each air outlet 220 and dispersed to both sides of the first clamp 20 / second clamp 21 to evenly contact the hair, thereby improving the hair styling effect.

[0026] It should be noted that the first heating plate 22 is disposed on the bulge of the first clamping plate 20, the second heating plate 23 is disposed on the recess of the first clamping plate 20, and the third heating plate 24 is disposed on the recess of the second clamping plate 21 that matches the bulge of the first clamping plate 20. Thus, when the first clamping plate 20 and the second clamping plate 21 are brought close together to clamp the hair, the hair can be heated evenly, thereby improving the hair styling effect.

[0027] like Figures 2 to 13 As shown, in one embodiment, the steam component includes a trough plate 30, a middle plate 31, and a back plate 32. The back plate 32 is disposed on the first clamping plate 20, and the back plate 32 and the first clamping plate 20 together clamp a heating plate. The middle plate 31 is disposed on the back plate 32, and the trough plate 30 is disposed on the middle plate 31. The trough plate 30 and the back plate 32 together clamp the middle plate 31.

[0028] It should be noted that both the slot plate 30 and the back plate 32 are made of metal with high thermal conductivity (for example, both the slot plate 30 and the back plate 32 are made of aluminum or copper). The back plate 32 is mounted on the first clamping plate 20, and one side of the back plate 32 and the inner bottom wall of the second clamping slot 222 clamp the second heating plate 23 together, so that the heat of the second heating plate 23 can be conducted to the back plate 32. The middle plate 31 is mounted on the back plate 32 and is made of high-temperature resistant silicone. The slot plate 30 is mounted on the middle plate 31. Specifically, the slot plate 30 has several mounting holes, and several screws are passed through the mounting holes and screwed to the middle plate 31 and the back plate 32 in sequence, so that the slot plate 30 and the back plate 32 clamp the middle plate 31 together, thereby sealing the gap between the slot plate 30 and the back plate 32.

[0029] like Figure 9 As shown, in one embodiment, the trough plate 30 is provided with a first groove 300, a second groove 301 and a third groove 302. The two ends of the second groove 301 are respectively connected to the first groove 300 and the third groove 302. The middle plate 31 together with the first groove 300, the second groove 301 and the third groove 302 form a continuous curved water channel.

[0030] It should be noted that a first groove 300, a second groove 301, and a third groove 302 are formed on the side of the trough plate 30 near the middle layer plate 31, with the second groove 301 located between the first groove 300 and the third groove 302. Further, for ease of description, the side of the trough plate 30 with the first groove 300, second groove 301, and third groove 302 is defined as the front side. In one embodiment, the first groove 300 is located on the right side of the trough plate 30 and extends from the lower end to the upper end of the trough plate 30; the third groove 302 is located on the left side of the trough plate 30 and also extends from the lower end to the upper end of the trough plate 30; and the second groove 301 is located between the first groove 300 and the third groove 302, and is located at the upper end of the trough plate 30. This allows the first groove 300, second groove 301, and third groove 302 to collectively form a continuously curved water channel. Furthermore, the upper end of the second groove 301 is connected to the upper end of the first groove 300, and the middle and lower ends of the second groove 301 are connected to the upper and lower ends of the third groove 302, respectively. This allows steam to flow quickly from the second groove 301 to the third groove 302 and be evenly distributed within the third groove 302. Furthermore, the trough plate 30 is provided with several partitions 303, each partition 303 being disposed within the first groove 300 and the second groove 301, and the partitions 303 are staggered and spaced apart, forming an S-shaped curved structure within either the first groove 300 or the second groove 301, further increasing the flow time of water / steam within the trough plate 30.

[0031] like Figure 9 As shown, in one embodiment, the trough plate 30 is further provided with a water inlet trough 304 and a plurality of water outlet troughs 305. The water inlet trough 304 is connected to one end of the water channel, and each water outlet trough 305 is connected to the other end of the water channel.

[0032] It should be noted that the bottom of the trough plate 30 is provided with a water inlet groove 304, and the side of the trough plate 30 is provided with a number of spaced water outlet grooves 305. When the trough plate 30 and the back plate 32 clamp the middle plate 31 together, the side of the middle plate 31 away from the back plate 32, together with the water inlet groove 304 and each water outlet groove 305, forms a water inlet hole and a number of spaced water outlet holes. Furthermore, the water inlet hole is connected to the first groove 300, and each water outlet hole is connected to the third groove 302.

[0033] like Figure 7 , Figure 8 As shown, in one embodiment, the middle layer plate 31 has an inner groove 310 and a back groove 311 respectively on its two opposing sides, the groove plate 30 is disposed in the inner groove 310, and the back plate 32 is disposed in the back groove 311.

[0034] It should be noted that the middle layer plate 31 has an inner groove 310 and a back groove 311 on its opposite sides. When the groove plate 30 and the back plate 32 clamp the middle layer plate 31 together, the groove plate 30 is embedded in the inner groove 310, and part of the structure of the back plate 32 is embedded in the back groove 311. This causes the middle layer plate 31 to surround the gap between the groove plate 30 and the back plate 32, further improving the sealing performance between the groove plate 30 and the back plate 32. The part of the back plate 32 that is not embedded in the back groove 311 protrudes relative to the middle layer plate 31 to facilitate contact with the second heating plate 23 and improve heat conduction efficiency.

[0035] like Figure 7 , Figure 8 As shown, in one embodiment, the middle layer plate 31 is provided with a plurality of perforations 312, and the perforations 312 are distributed at intervals so that a support strip 313 is formed in the middle layer plate 31. Each perforation 312 is respectively connected to the first groove 300 and the third groove 302. The back plate 32 forms a first channel and a third channel with the first groove 300 and the third groove 302, respectively. The support strip 313 forms a second channel with the second groove 301.

[0036] It should be noted that the middle layer plate 31 has several spaced perforations 312, and the two ends of each perforation 312 are connected to the inner bottom wall of the inner groove 310 and the back groove 311, respectively, so that a support strip 313 is formed inside the middle layer plate 31. For ease of description, each perforation 312 is defined as the first perforation and the second perforation. When the groove plate 30 and the back plate 32 clamp the middle layer plate 31 together, the first perforation is connected to the first groove 300, the third groove 302 is connected to the second perforation, and the support strip 313 seals the second groove 301. In this way, the back plate 32, the first groove 300 and the first perforation together form the first chamber, the support strip 313 and the second groove 301 together form the second chamber, and the back plate 32, the second perforation and the third groove 302 together form the third chamber. Furthermore, one end of the first chamber is connected to the water inlet, the other end of the first chamber is connected to the second chamber, the end of the second chamber away from the first chamber is connected to the third chamber, and the end of the third chamber away from the second chamber is connected to each water outlet, so that the first, second, and third chambers together form a continuous, curved water channel. Furthermore, the first groove 300, the second groove 301, and the third groove 302 are of the same depth, but the areas of the first groove 300 and the third groove 302 are larger than that of the second groove 301, so that the volume of the first and third chambers is larger than the volume of the second chamber. Specifically, since the first groove 300 and the third groove 302 are connected through the first and second perforations respectively, when the groove plate 30 and the back plate 32 clamp the middle plate 31 to form the first and third chambers, the volume inside the first chamber is the sum of the volume formed by the depth and width of the first groove 300 and the volume inside the first perforation. The volume inside the third chamber is the sum of the volume formed by the depth and width of the third groove 302 and the volume inside the second perforation. The second chamber is formed by the support strip 313 sealing the second groove 301, so the volume inside the second chamber depends on the width and depth of the second groove 301. This results in the internal volume of the first and third chambers being larger than the internal volume of the second chamber. The two ends of the second chamber are connected to the first and third chambers respectively, and the water channel they form has a structure that is large at both ends and small in the middle. Thus, when water enters the first chamber, the first chamber will be filled with water before flowing into the second chamber. During this water filling process, the water stays in the first chamber for a longer period of time, which increases the time that the first heating plate 22 heats the water in the first chamber through the back plate 32. This allows the water in the first chamber to heat up quickly and reach the vaporization temperature rapidly.

[0037] It should be noted that, since the internal volume of the second chamber is smaller than that of the first chamber, and the second chamber has a long, narrow structure, when water from the first chamber flows through the second chamber into the third chamber, two situations will occur. First, when the user starts using the device, the water and the second heating plate 23 can only work after the power is turned on. This means that water begins to enter the first chamber before the second heating plate 23 starts to heat up. As the water gradually fills the first chamber, the temperature of the water in the first chamber gradually increases due to the conduction of the second heating plate 23 to the back plate 32 and the heating of the water in the first chamber. During this process, after the water fills the first chamber, the water temperature is still below the vaporization temperature, and the water will still flow into the second chamber. Thus, when water flows from the large-volume chamber into the small-volume second chamber with a narrow channel, the water flow rate will increase, allowing the water to pass through the second chamber quickly and be sprayed into the third chamber rapidly. In this way, the second chamber becomes an acceleration channel between the first and third chambers. When unvaporized water enters the third chamber, the back plate 32 heats the water inside, causing it to rapidly heat up and vaporize, then spray out from the water outlets. During this process, since the side of the back plate 32 furthest from the second heating plate 23 forms the first and third chambers with the first perforation, the second perforation, the first groove 300, and the third groove 302 respectively, when the back plate 32 heats the water in the first chamber, it also simultaneously heats the air in the third chamber. Therefore, when the unvaporized water sprayed from the second chamber enters the preheated third chamber, its temperature allows the already heated water to continue to heat up rapidly to reach the vaporization temperature, thus forming steam that is sprayed out from the water outlets. Secondly, after the user has used the device for a period of time, the temperature of the back panel 32 has risen, allowing water entering the first chamber to quickly reach vaporization temperature and form steam. As water continues to vaporize in the first chamber and is continuously injected, the space within the first chamber for water vaporization is continuously compressed, causing the air pressure in the first chamber to gradually increase. This results in a faster flow rate of steam through the second chamber, leading to a faster steam ejection from the second chamber to the third chamber and a larger volume of steam ejected. Furthermore, since the third chamber is larger than the second chamber, the steam flow rate decreases after it is ejected from the second chamber into the third chamber, allowing the steam to fill the third chamber completely. Furthermore, during this process, the steam in the third chamber may experience slight condensation due to its slow flow speed, resulting in less refined steam. Therefore, when the steam flows slowly in the third chamber, the back plate 32 can reheat the steam in the third chamber to further vaporize it, making the steam more refined and increasing the amount of steam. At the same time, it increases the air pressure in the third chamber, thereby allowing the steam in the third chamber to be ejected from each water outlet in greater quantity and finer.

[0038] like Figures 3 to 7As shown, in one embodiment, the middle layer plate 31 has a plurality of through holes 314 on its side and a plurality of air vents 220, and the air vents 220 are arranged in a linear manner. The two ends of each through hole 314 are connected to each water outlet 305 and each air vent 220, respectively.

[0039] It should be noted that a number of through holes 314 are provided on one side of the middle layer plate 31, and the through holes 314 are arranged in a straight line along the side length of the middle layer plate 31. When the trough plate 30 is embedded in the inner trough 310 so that the water outlet trough 305 and the inner bottom wall of the inner trough 310 together form a number of water outlet holes, the water outlet holes will be connected to the through holes 314 one by one. Furthermore, the first clamping plate 20 has several air vents 220 arranged in a straight line, with each air vent 220 having its two ends connected to the inner and outer sides of the first clamping plate 20, respectively. When the groove plate 30 is screwed to the first clamping plate 20 through the middle plate 31 and the back plate 32, in addition to the back plate 32 and the first clamping plate 20 clamping the second heating plate 23 within the second heating groove, the middle plate 31 also causes the end of each through hole 314 away from each water outlet to abut against each air vent 220, thereby connecting both ends of each through hole 314 to each water outlet and each air vent 220, respectively. In this way, the steam in the third chamber can flow through each water outlet and through each through hole 314 and be ejected from each air vent 220, thus entering the gap between the first clamping plate 20 and the second clamping plate 21 and spreading evenly to both sides to contact the hair, thereby improving the hair styling effect.

[0040] like Figure 1 , Figures 4 to 6 As shown, in one embodiment, the first clamping plate 20 is also provided with an arc groove 223, which is connected to each air outlet 220.

[0041] It should be noted that, due to the small distance between the first clamping plate 20 and the second clamping plate 21, when steam is ejected from each vent 220, the steam will concentrate on a fixed position on the side of the second clamping plate 21 closest to the first clamping plate 20. Under prolonged spraying, water droplets will condense at the openings of the vents 220 closest to the second clamping plate 21. Furthermore, an arc groove 223 is formed on the side of the first clamping plate 20 closest to the second clamping plate 21. The two ends of the arc groove 223 are connected to the two ends of the first clamping plate 20, so that when the first clamping plate 20 and the second clamping plate 21 clamp the hair together, a channel is formed between the first clamping plate 20 and the second clamping plate 21, and the ends of each vent 220 away from the through hole 314 are connected to the arc groove 223. In this way, the water droplets formed at the openings of the vents 220 can flow out from the arc groove 223, preventing a large number of water droplets from remaining between the first clamping plate 20 and the second clamping plate 21, thus affecting the hair styling effect.

[0042] like Figure 2 , Figure 3 As shown, in one embodiment, the steam assembly also includes a water pump 34, a water tank 35, a control board 36, and several sensors 37.

[0043] It should be noted that both the water tank 35 and the water pump 34 are mounted on the first housing 10, and the control board 36 is mounted on the second housing 11. The water tank 35 is used to store water and is connected to the inlet of the water pump 34 via a water pipe. The outlet of the water pump 34 is connected to the inlet, and the water pump 34 is electrically connected to the control board 36. The control board 36 is a circuit board structure, and it controls the water pump 34 to transport the water in the water tank 35 to the first chamber. Furthermore, a sensing groove 2220 is provided on the inner bottom wall of the second clamping groove 222, and one of the sensing elements 37 is disposed in the sensing groove 2220. The first clamping groove 221... The width of the third clamping groove 210 is greater than the width of the first heating plate 22 and the third heating plate 24. This ensures that when the first heating plate 22 and the third heating plate 24 are positioned within the first clamping groove 221 and the third clamping groove 210, each groove has space sufficient to accommodate one sensor 37. Therefore, two other sensors 37 are respectively positioned within this space, allowing each sensor 37 to detect the temperature of the first heating plate 22, the second heating plate 23, and the third heating plate 24 in a one-to-one correspondence. Furthermore, each sensor 37 is a temperature sensor, and each sensor 37 is electrically connected to the control board 36. This allows the control board 36 to continuously monitor the temperature of the first heating plate 22, the second heating plate 23, and the third heating plate 24, and adjust the water supply of the water pump 34 according to temperature changes, achieving a reasonable and efficient steam output.

[0044] like Figure 11 , Figure 12 As shown, in one embodiment, the first clamping plate 20 is provided with at least two rows of air holes 220, and the groove plate 30 is provided with a first groove 300 and two second grooves 301. One end of each of the two second grooves 301 is connected to the first groove 300, and the other end of each second groove 301 is connected to the two rows of air holes 220 respectively.

[0045] It should be noted that, in one embodiment, two spaced-apart bridging blocks 224 are integrally formed on the side of the first clamping plate 20 away from the second clamping plate 21, and the two bridging blocks 224 are located between the bulge and the recess; each exhaust hole 220 has at least three outlet holes, and the two outlet holes 220 are respectively opened in the two bridging blocks 224, and each outlet hole 220 is connected to the side of the first clamping plate 20 near the second clamping plate 21 and the end face of the bridging block 224 away from the first clamping plate 20. Further, the groove plate 30 has a first groove 300 and two second grooves 301. The groove plate 30 passes through the middle plate 31 and the back plate 32 by screws, so that the first groove 300 and the two second grooves 301 respectively form a first chamber and two second chambers, and the two second chambers are respectively connected to the two exhaust holes 220. Furthermore, two second grooves 301 are located on both sides of the first groove 300. The first groove 300 includes a square portion 3000 and a strip-shaped portion 3001. The square portion 3000 is larger than the strip-shaped portion 3001. The square portion 3000 is located at the lower end of the groove plate 30, and the strip-shaped portion 3001 is located at the upper end of the groove plate 30. The lower end of the strip-shaped portion 3001 communicates with the square portion 3000, and the upper end of the strip-shaped portion 3001 communicates with the two second grooves 301 respectively, so that the strip-shaped portion 3001 has a T-shaped structure. Furthermore, when the groove plate 30 and the back plate 32 clamp the middle plate 31 together to seal the first groove 300 and the two second grooves 301, a three-way interconnected channel tending towards a T-shape and with narrow connection positions will be formed. Thus, when water flows from the square portion 3000 in the first chamber through the strip portion 3001, the water flow is rapidly sprayed into the two second chambers by the strip portion. Furthermore, the two second grooves 301 are larger than the strip portion 3001, which slows down the speed of the water after it is sprayed out of the strip portion 3001, thereby allowing the water to be evenly distributed in the two second chambers. In one embodiment, the middle plate 31 is made of a highly thermally conductive metal material, so that the second heating plate 23 can conduct heat to the middle plate 31 through the back plate 32, and heat the water in the first chamber and the two second chambers through the middle plate 31. Furthermore, two flat holes 315 are provided on the middle plate 31, and two elongated holes 320 are provided on the back plate 32. A protrusion 2240 is provided on the end of each of the two bridge blocks 224 away from the first clamping plate 20. The shape and size of the protrusion 2240 are adapted to the flat holes 315 / elongated holes 320. The end of each air outlet 220 away from the first clamping plate 20 is also distributed on the end of the two protrusions 2240 away from the first clamping plate 20.When the back plate 32 is placed on the first clamping plate 20, and the back plate 32 and the groove plate 30 clamp the middle plate 31 together so that the two flat holes 315 and the two long holes 320 are connected one-to-one, the two bridge blocks 224 at the end faces away from the first clamping plate 20 respectively seal the two long holes 320, and at the same time, the two protrusions 2240 fit through the flat holes 315 and the long holes 320 respectively and extend into the two second chambers, so that the steam in the two second chambers can be ejected from each of the air outlets 220 through the two bridge blocks 224 respectively.

[0046] like Figures 14 to 17 As shown, in one embodiment, the steam assembly further includes a comb rack 25 and a locking rod 26. The comb rack 25 is integrally formed with a plurality of comb teeth 250, and each comb tooth 250 is distributed in a straight line at intervals. The locking rod 26 is integrally formed with a tooth cap 260 and a rod body 261, and one side of the tooth cap 260 is disposed on one end of the rod body 261. A tooth groove 225 is formed on the outer side wall of the first clamping plate 20, and a screw hole 2250 is formed on the inner side wall of the tooth groove 225. A locking hole 2501 is formed on the comb rack 25, and the comb rack 25 is adapted to engage with the tooth groove 225, so that the locking hole 2501 and the screw hole 2250 are coaxially aligned.

[0047] It should be noted that the end of the rod 261 away from the tooth cap 260 passes through the locking hole 2501 and is screwed into the screw hole 2250, so that the locking rod 26 fixes the comb bar 25 to the first clamping plate. Furthermore, the comb teeth 250 have a semi-elliptical structure, and the long axis of the comb teeth 250 is consistent with the wave extension direction of the first clamping plate (i.e., the direction of the long axis is consistent with the combing direction). The shape of the tooth cap 260 is consistent with the shape of each comb tooth 250, allowing the user to rotate the rod 261 by hand by turning the tooth cap 260, thereby removing the comb bar 25 from the tooth groove 225. Furthermore, the comb bar 25 has an inner groove 2502, and the locking hole 2501 has an inner bottom wall of the inner groove 2502. Specifically, because the four edges of the side of the tooth cap 260 near the shaft 261 are necessarily blunted and have rounded corners in cross-section, when the tooth cap 260 is tightly fitted to the inner bottom wall of the recessed groove 2502, a gap is formed between the rounded corners and the inner bottom wall. When hair passes through this gap, it will get stuck. Therefore, by abutting the tooth cap 260 against the inner bottom wall of the recessed groove 2502, the gap is made lower than the surface of the comb teeth 25, allowing the gap to avoid passing hair and thus preventing hair from getting stuck, which would affect the timeliness and smoothness of combing, thereby improving the user experience. It should be noted that, in one embodiment, the comb bar 25 can be configured with either comb teeth 250 or without comb teeth 250, and both types of comb bar 25 can be detachably mounted on the first clamping plate via the locking rod 26. For ease of description, the one with comb teeth 250 is defined as the first comb bar, and the one without comb teeth 250 is defined as the second comb bar. When the first comb bar is positioned within the tooth groove 225, the user can style their hair by combing it to create a curled-end hairstyle. It should be noted that the second clamping plate 21 has clearance grooves 211 at positions corresponding to each comb tooth 250 to prevent the first clamping plate 20 and the second clamping plate 21 from being unable to approach each other due to the protruding comb teeth 250. When the second comb tooth is positioned within the tooth groove 225, the user can style their hair by clamping it to create a wavy style. In this way, the egg roll hair styling tool of this application can adapt to various hair styling methods to meet the different styling needs of users.

[0048] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
