Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of steam generators, and in particular to a steam generator for hair-straightening combs.BACKGROUND

[0002] The proliferation of technology has facilitated the integration of hair-straightening combs into consumer lifestyles. A hair-straightening comb is an electronic device that operates at elevated temperatures to soften and straighten hair. The device utilizes electric heating to warm either the comb teeth or the base plate, allowing the high temperature to heat and soften the hair as it is combed, thereby achieving a straightening effect. However, exposure to high temperatures can lead to moisture loss in the hair, resulting in increased dryness and potential damage. Moreover, conventional hair straightening tools typically employ a clamp design, featuring electric heating plates positioned on the inner sides of the clamps. The hair is straightened by the application of heat from these two heating plates. These tools can only straighten the hair and necessitate the use of a separate comb, and it is often required to replenish moisture through an external spray device to mitigate excessive dryness. Alternatively, some hair-straightening combs incorporate a steam generator that simultaneously provides moisture during the straightening process. Current steam generators on the market primarily produce high temperatures by heating a conductive plate, which subsequently generates steam through the introduction of clean water. This method tends to produce significant amounts of steam and generates considerable noise as the water evaporates upon contact with the heated plate. Such operational characteristics can detract from the user experience, and the prolonged exposure of the heating plate to both high and low-temperature environments may lead to damage and increased costs.SUMMARY

[0003] In order to solve the problems that the steam mode of the existing steam generator has a large amount of steam and generates a lot of noise after the water contacts the high-temperature heating plate and evaporates, the operating experience is poor, the heating plate is easily damaged due to being in a high temperature and local low-temperature environment for a long time, and the cost is higher, the present disclosure provides a steam generator for hair-straightening combs.

The first water-storing sound-insulating cotton block fills the first groove, the second water-storing sound-insulating cotton block is located in the second groove, and the steam port connects the air-spraying groove and the second groove.

[0013] Preferably, the isolation blocking bar is higher than the first water-storing sound-insulating cotton block and the second water-storing sound-insulating cotton block, and is lower than the highest point of the evaporation groove.

[0014] Preferably, a blocking block is provided on one side of the water tank cover away from the steam column, and the blocking block is aligned with a pipe opening of the water injection pipe extending into the first groove.

[0015] Preferably, a first channel is formed between the blocking block and the isolation blocking bar, and a second channel is formed, in a direction parallel to the isolation blocking bar, between two ends of the blocking block and the side wall of the water tank cover.

[0025] In the present disclosure, the steam generator for hair-straightening combs includes an evaporation assembly and a heating plate assembly.

A first water-storing sound-insulating cotton block is arranged in the evaporation groove and is located between the water injection pipe and the bottom of the evaporation groove, such that the position of the first water-storing sound-insulating cotton block corresponds to the position of the water injection pipe extending into the evaporation groove, thereby enabling the water injection pipe extending into the evaporation groove to sink into the first water-storing sound-insulating cotton block located below the water injection pipe. When water is injected into the evaporation groove through the water injection pipe, the water flowing out of the water injection pipe will first contact the first water-storing sound-insulating cotton block below the water injection pipe, so as to diffuse the water evenly to the bottom of the evaporation groove through the first water-storing sound-insulating cotton block, thereby buffering the water injection and reducing the noise during the water injection. When high-temperature heating is performed at the lower end of the evaporation water tank through the heating plate assembly, the water in each part of the first water-storing sound-insulating cotton block can fully contact the bottom of the evaporation groove to prevent the heating plate from being in a high temperature and local low-temperature environment for a long time and being easily damaged. In addition, since the interior of the first water-storing sound-insulating cotton block is a loose and porous structure, the water is fully contacted in the first water-storing sound-insulating cotton block during the evaporation process, such that steam can be generated more evenly, excessive steam generation can be prevented, and the noise generated during water evaporation can be effectively reduced.BRIEF DESCRIPTION OF DRAWINGS

[0050] Please refer to FIGS. 1 to 4. A first embodiment of the present disclosure provides a steam generator for hair-straightening combs 100, including an evaporation assembly 1 and a heating plate assembly 2. The evaporation assembly 1 includes an evaporation water tank 3 and a water injection pipe 4. The evaporation water tank 3 is provided with an evaporation groove 311 and an air-spraying groove 312 connected to the evaporation groove 311. The heating plate assembly 2 is connected to the side of the evaporation water tank 3 away from the evaporation groove 311. The evaporation groove 311 is provided with a first water-storing sound-insulating cotton block 51, and the first water-storing sound-insulating cotton block 51 is located between the water injection pipe 4 and the bottom 3110 of the evaporation groove 311.

[0051] Specifically, one end of the water injection pipe 4 extends into the evaporation groove 311, and the other end thereof can be connected to an external water injection device, for example, an external water pump can provide clean water to the first water-storing sound-insulating cotton block 51 in the evaporation groove 311 through the water injection pipe 4. The first water-storing sound-insulating cotton block 51 is arranged corresponding to the pipe mouth of the water injection pipe 4 extending into the evaporation groove 311 and is located between the water injection pipe 4 extending into the evaporation groove 311 and the bottom 3110 of the evaporation groove 311. That is, the first water-storing sound-insulating cotton block 51 is clamped between the water injection pipe 4 and the bottom 3110 of the evaporation groove 311, which can avoid displacement of the first water-storing sound-insulating cotton block 51 and improve the stability of the first water-storing sound-insulating cotton block 51. The water injection pipe 4 and the first water-storing sound-insulating cotton block 51 are sequentially arranged along the gravity direction, and the first water-storing sound-insulating cotton block 51 is located at the lower end of the water injection pipe 4, such that the water flowing out of the water injection pipe 4 can first pass through the first water-storing sound-insulating cotton block 51 below for buffering and diffusion before flowing into the bottom 3110 of the evaporation groove 311. The heating plate assembly 2 is arranged on the side of the evaporation water tank 3 away from the evaporation groove 311, that is, the side of the bottom 3110 of the evaporation groove 311 away from the first water-storing sound-insulating cotton block 51.

[0052] More specifically, after the operator turns on the hair-straightening comb, the water injection pipe 4 drips clean water into the first water-storing sound-insulating cotton block 51, and the evaporation water tank 3 is heated by the heating plate assembly 2. The temperature of the bottom 3110 of the evaporation groove 311 increases, such that the clean water in the first water-storing sound-insulating cotton block 51 contacts the bottom 3110 of the evaporation groove 311 and evaporates. The first water-storing sound-insulating cotton block 51 can effectively reduce the noise generated by water evaporation. After the generated steam passes through the upper surface of the first water-storing and sound-insulation block 51, the steam enters the air-spraying groove 312 connected to the evaporation groove 311, and the steam is sprayed via the air-spraying groove 312. This arrangement utilizes a straightforward design, consistent operational reliability, and an ability to significantly diminish the noise produced during the evaporation process.

[0053] It can be understood that the first water-storing sound-insulating cotton block 51 is arranged between the water injection pipe 4 and the bottom 3110 of the evaporation groove 311, such that the position of the first water-storing sound-insulating cotton block 51 corresponds to the position of the water injection pipe 4 extending into the evaporation groove 311, and the water injection pipe 4 extending into the evaporation groove 311 can sink into the first water-storing sound-insulating cotton block 51 located below the water injection pipe 4. When water is injected into the evaporation groove 311 via the water injection pipe 4, the water flowing out of the water injection pipe 4 will first contact with the first water-storing sound-insulating cotton block 51 below the water injection pipe 4, so as to diffuse the water evenly to the bottom 3110 of the evaporation groove 311 through the first water-storing sound-insulating cotton block 51, thereby buffering the water injection process and reducing the noise during the water injection. In addition, when high-temperature heating is performed at the lower end of the evaporation water tank 3 through the heating plate assembly 2, the moisture in each part of the first water-storing sound-insulating cotton block 51 can fully contact with the bottom 3110 of the evaporation groove 311, so as to prevent the heating plate from being in a high temperature and local low-temperature environment for a long time and being easily damaged. Further, since the interior of the first water-storing and sound-insulating cotton block is of a loose and porous structure, the moisture is fully contacted in the first water-storing sound-insulating cotton block 51 during the evaporation process, such that steam can be generated more evenly, excessive steam generation can be prevented, and the noise generated during water evaporation can be effectively reduced.

[0054] Please refer to FIG. 5. Further, the first water-storing sound-insulating cotton block 51 is higher than the end of the water injection pipe 4 close to the evaporation groove 311, and is lower than the highest point 3114 of the evaporation groove 311.

[0055] It can be understood that the first water-storing sound-insulating cotton block 51 has a loose porous structure and has a certain degree of expansion and contraction, and the height h1 (as shown in h1 in FIG. 5) of the first water-storing sound-insulating cotton block 51 is configured to be higher than the height D (as shown in D in FIG. 5) of the end of the water injection pipe 4 close to the evaporation groove 311. When the first water-storing sound-insulating cotton block 51 is arranged between the water injection pipe 4 and the bottom 3110 of the evaporation groove 311, at least part of the water injection pipe 4 will directly sink into the first water-storing sound-insulating cotton block 51, which is more conducive to the full contact between the water flowing out of the water injection pipe 4 and the first water-storing sound-insulating cotton block 51, and the water flowing out of the water injection pipe 4 is prevented from rushing out of the first water-storing sound-insulating cotton block 51 and directly impacting the evaporation groove 311, further reducing the possibility of noise generation. The highest point 3114 of the evaporation groove 311 can be the height of the notch of the evaporation groove 311. The height h1 of the first water-storing sound-insulating cotton block 51 is required to be lower than the height H (H shown in FIG. 5) of the highest point 3114 of the evaporation groove 311, so as to provide a flow channel for the steam generated in the evaporation groove 311.

[0056] Please refer to FIGS. 2 and 3. Further, the evaporation water tank 3 includes a water tank base 31 and a water tank cover 32. The water tank base 31 is provided with the evaporation groove 311 and the air-spraying groove 312. The water tank base 31 is provided with a steam port 313. The evaporation groove 311 is connected to the air-spraying groove 312 through the steam port 313.

[0057] It can be understood that the water tank cover 32 can cover the water tank base 31. The water tank base 31 is provided with a steam port 313, such that the steam generated in the evaporation groove 311 enters the air-spraying groove 312 through the steam port 313. Therefore, the steam passing rate and the passing amount per unit time between the evaporation groove 311 and the air-spraying groove 312 can be controlled by the arrangement of the steam port 313, so as to prevent the occurrence of either excessive or insufficient steam flow into the air-spraying groove 312, as well as the steam entering the air-spraying groove 312 at an inappropriate velocity (too much or too little).

[0058] Please refer to FIG. 2. Further, a plurality of steam columns 6 are provided on the water tank cover 32. The positions of the plurality of steam columns 6 correspond to the positions of the air-spraying groove 312. Thus, the steam enters the air-spraying groove 312 through the steam port 313, and the steam is sprayed through the plurality of steam columns 6, such that the steam in the air-spraying groove 312 directly enters the comb tooth structure through the steam columns 6, thereby increasing the steam efficiency.

[0059] Please refer to FIG. 2. Further, the plurality of steam columns 6 are arranged at intervals according to a preset arrangement, and the total length of the plurality of steam columns 6 is less than or equal to the length of the air-spraying groove 312, such that the plurality of steam columns 6 after being arranged match the shape and size of the air-spraying groove 312, which ensures that each steam column 6 in the air-spraying groove 312 can spray steam and that the efficiency and amount of steam sprayed by the plurality of steam columns 6 can be made more uniform to avoid uneven steam spray affecting the straight hair effect. In addition, by arranging the length of the plurality of steam columns 6 arranged at intervals to be close to or equal to the length of the air-spraying groove 312, it can be ensured that the accumulation of steam in the air-spraying groove 312 is avoided and the manufacturing cost is reduced.

[0060] Please refer to FIG. 3. Further, the steam port 313 is located at one end of the evaporation groove 311 away from the water injection pipe 4, such that there is a certain distance between the water injection pipe 4 and the steam port 313, reserving time for the first water-storing sound-insulating cotton block 51 to absorb the water flowing out of the water injection pipe 4, so as to prevent the water flowing into the water injection pipe 4 from directly flowing into the air-spraying groove 312 through the steam port 313.

[0061] Please refer to FIG. 3 and FIG. 4. Further, a second water-storing sound-insulating cotton block 52 is disposed in the evaporation groove 311. The second water-storing sound-insulating cotton block 52 is disposed at one end of the evaporation groove 311 away from the water injection pipe 4.

[0062] Specifically, the second water-storing sound-insulating cotton block is arranged at one end of the evaporation groove 311 away from the water injection pipe 4 and is spaced apart from the first water-storing sound-insulating cotton block 51. The position of the second water-storing sound-insulating cotton block 52 is arranged to be offset from the position of the steam port 313, thereby preventing the second water-storing sound-insulating cotton block 52 from blocking the steam port 313 and affecting the steam entering the air-spraying groove 312.

[0063] It can be understood that clean water is dripped into the first water-storing sound-insulating cotton block 51 through the water injection pipe 4, and the evaporation water tank 3 is heated through the heating plate assembly 2. The temperature of the bottom 3110 of the evaporation groove 311 increases, such that the clean water in the first water-storing sound-insulating cotton block 51 contacts the bottom 3110 of the evaporation groove 311 and evaporates. The first water-storing sound-insulating cotton block 51 can effectively reduce the noise generated by water evaporation. The generated steam can pass through the upper surface of the second water-storing sound-insulating cotton block and moisten the second water-storing sound-insulating cotton block 52, and then evaporate simultaneously. The steam enters the air-spraying groove 312 through the steam port 313, and the steam is sprayed through the plurality of steam columns 6. The structure is simple, the performance is stable, and the noise generated during evaporation can be effectively reduced. After the steam is sprayed from the air-spraying groove 312, the steam will contact the upper surface of the second water-storing sound-insulating cotton block 52 and condense into water droplets again, which can achieve effective steam buffering when the device is just turned on.

[0064] Please refer to FIG. 5. Further, the second water-storing sound-insulating cotton block 52 is lower than the highest point 3114 of the evaporation groove 311.

[0065] It can be understood that the height h1 of the first water-storing sound-insulating cotton block 51 and the height h2 of the second water-storing sound-insulating cotton block 52 (as h2 shown in FIG. 5) are both lower than the height H of the highest point 3114 of the evaporation groove 311. It can be seen that the first water-storing sound-insulating cotton block 51 and the second water-storing sound-insulating cotton block 52 are both lower than the evaporation groove 311, so as to prevent the internal gas of the first water-storing sound-insulating cotton block 51 and the second water-storing sound-insulating cotton block 52 from expanding due to internal gas expansion when water evaporates, causing the volume to increase and resulting in the inability to produce steam normally.

[0066] Please refer to FIGS. 3 and 5. Further, an isolation blocking bar 13 is arranged between the first water-storing sound-insulating cotton block 51 and the second water-storing sound-insulating cotton block 52. The isolation blocking bar 13 separates the evaporation groove 311 into a first groove 3111 and a second groove 3112. Part of the water injection pipe 4 extends into the first groove 3111. The first water-storing sound-insulating cotton block 51 fills the first groove 3111, and the second water-storing sound-insulating cotton block 52 is located in the second groove 3112. The steam port 313 connects the air-spraying groove 312 and the second groove 3112.

[0067] Specifically, the isolation blocking bar 13 can separate the evaporation groove 311 into a first groove 3111 and a second groove 3112 which are not connected except for the portion above the groove notch, such that the bottom of the first groove 3111 and the bottom of the second groove 3112 are not connected, and the groove wall of the first groove 3111 and the groove wall of the second groove 3112 are also not connected, thus the steam generated by evaporation in the first groove 3111 can only pass through the upper surface of the first water-storing sound-insulating cotton block 51 and enter the second groove 3112 to moisten the second water-storing sound-insulating cotton block 52. The steam port 313 connects the air-spraying groove 312 and the second groove 3112, therefore the arrangement of the isolation blocking bar 13 not only separates the evaporation groove 311 into the first groove 3111 and the second groove 3112 which are isolated from each other, but also effectively prevents the clean water flowing into the water injection pipe 4 from directly flowing into the air-spraying groove 312 through the steam port 313 to cause water accumulation.

[0068] It should be noted that the first water-storing sound-insulating cotton block 51 fills the first groove 3111, such that the boundary of the first water-storing sound-insulating cotton block 51 can abut against the groove wall of the first groove 3111, thereby enhancing the stability of the first water-storing sound-insulating cotton block 51 in maintaining the current state. It can also be ensured that the first water-storing sound-insulating cotton block 51 completely covers the bottom 3110 of the first groove 3111, so as to ensure the water absorption effect and steam effect of the first water-storing sound-insulating cotton block 51. Except for the boundary of the second water-storing sound-insulating cotton block 52 near the steam port 313, the remaining boundaries of the second water-storing sound-insulating cotton block 52 abut against the groove wall of the second groove 3112 and the groove wall formed by the isolation blocking bar 13, thereby stabilizing the position of the second water-storing sound-insulating cotton block 52.

[0069] Please refer to FIG. 5. Further, the isolation blocking bar 13 is higher than the first water-storing sound-insulating cotton block 51 and the second water-storing sound-insulating cotton block 52, and is lower than the highest point 3114 of the evaporation groove 311.

[0070] It can be understood that the height h3 of the isolation blocking bar 13 (as h3 shown in FIG. 5) is required to be greater than the height h1 of the first water-storing sound-insulating cotton block 51 and the height h2 of the second water-storing sound-insulating cotton block 52. This can avoid direct contact between the first water-storing sound-insulating cotton block 51 and the second water-storing sound-insulating cotton block 52 exposed from the isolation blocking bar 13 due to the first water-storing sound-insulating cotton block 51 and the second water-storing sound-insulating cotton block 52 being higher than the isolation blocking bar 13, prevent water from passing through the gap between the first water-storing sound-insulating cotton block 51 and the second water-storing sound-insulating cotton block 52, and prevent a large amount of water from the first groove 3111 from entering the second groove 3112, such that the second water-storing sound-insulating cotton block 52 can achieve an evaporation buffering effect. In addition, the height of the isolation blocking bar 13 is set as described above such that the water injected by the water injection pipe 4 is blocked by the isolation blocking bar 13, so as to further prevent the clean water dripping into the water injection pipe 4 from directly flowing into the air-spraying groove 312 through the steam port 313 and causing water accumulation.

[0071] Please refer to FIGS. 5 to 7. Further, a blocking block 321 is provided on the side of the water tank cover 32 away from the steam column 6. The blocking block 321 is aligned with the pipe mouth of the water injection pipe 4 extending into the first groove 3111 to further prevent the water in the water injection pipe 4 from directly rushing into the second groove 3112, and prevent the water from directly flowing into the air-spraying groove 312 through the steam port 313 to cause water accumulation, thereby improving the control of water outflow from the water injection pipe 4.

The first channel 121 and the second channel 12 are combined to form a steam channel 12, making the distribution range of the steam channel 12 wider, such that the steam can pass more evenly from the top of the first water-storing sound-insulating cotton block 51 to the top of the second water-storing sound-insulating cotton block 52, and the uneven distribution of steam and steam accumulation at the boundary corners can be prevented.

[0073] Please refer to FIGS. 4 and 5. Further, the position of the blocking block 321 and that of the isolation blocking bar 13 are offset from each other, such that through the cooperation of the isolation blocking bar 13 and the blocking block 321, water can be blocked from flowing out from the upper and lower ends of the water injection pipe 4. This further prevents the water in the water injection pipe 4 from being directly injected into the second groove 3112 and affecting the steam effect.

[0074] Optionally, the distance between the blocking block 321 and the water injection pipe 4 is greater than the distance between the isolation blocking bar 13 and the water injection pipe 4, which can facilitate the steam to enter the top of the second water-storing sound-insulating cotton block 52 and avoid the accumulation of steam at the angle between the blocking block 321 and the water tank cover 32.

[0078] It can be understood that by providing isolation guide ports 9 at the upper end of the steam column isolation covers 8 and connecting the isolation guide ports 9 with the air outlets 61 of the steam columns 6, the steam in the air-spraying groove 312 is connected to the ambiance. In addition, by setting the size and direction of the isolation guide ports 9, the efficiency, amount and gas outlet direction of the steam outflow can be controlled, and the controllability of the steam outflow state is improved.

[0079] Optionally, in this embodiment, there is no restriction on the size and direction of the isolation guide port 9, which can be selected according to the actual comb tooth structure, as long as the isolation guide port 9 is connected to the air outlet 61 of the steam column 6.

[0080] Please refer to FIG. 9. Further, the isolation guide port 9 faces the side of the flexible isolation plate 7 where the steam column isolation cover 8 is not provided, such that the steam can be accurately sprayed onto the comb tooth structure in the middle of the upper end face of the flexible isolation plate 7, thereby realizing directional steam spraying, which can effectively prevent steam overflow to cause burns, has a simple structure, a more uniform steam volume and generates less noise.

In addition, the convex ends of the plurality of steam buffer blocks 10 are lower than the highest point 3114 of the evaporation groove 311, which is conducive to avoiding interference with the steam entering the air-spraying groove 312 when the amount of steam is small.

[0085] It can be understood that the side of the water tank base 31 away from the evaporation groove 311 is the lower end face of the water tank base 31, therefore the connecting plate 22 is connected to the lower end face of the water tank base 31 by a plurality of locking screws 23. The heating plate 21 is arranged on the upper end face of the connecting plate 22, and the upper end face of the heating plate 21 cooperates with the lower end face of the evaporation position of the water tank base 31, so as to achieve a firm connection between the heating plate assembly 2 and the evaporation assembly 1, and facilitate disassembly. The evaporation position of the water tank base 31 may be defined as a heating area where the heating plate 21 heats the water tank base 31. In addition, the heating plate 21 is arranged between the connecting plate 22 and the water tank base 31, such that the clean water at the bottom 3110 can be fully heated and evaporated by the heating plate 21 to make the steam volume more stable.

Further, two limit blocks 314 are provided on the side of the water tank base 31 away from the evaporation groove 311, and the heating plate 21 is located between the two limit blocks 314, such that the heating plate 21 is clamped between the two limit blocks 314 to limit the position of the heating plate 21 and prevent the heating plate 21 from shifting and affecting the heating effect.

[0087] The working principle of the embodiment of the present disclosure is as follows. The operator turns on the hair-straightening comb, and an external water pump gradually drips clean water into the first water-storing sound-insulating cotton block 51 through the water injection pipe 4. The heating plate 21 generates heat, and the temperature of the bottom 3110 of the evaporation groove 311 increases. The moisture at the bottom 3110 of the first water-storing sound-insulating cotton block 51 contacts with the bottom 3110 of the evaporation groove 311 and evaporates, and the steam passes through the first water-storing sound-insulating cotton block 51, which can effectively reduce the noise generated during evaporation. The steam then passes through the steam channel 12 from the top of the steam buffer block 10, and can be synchronously moistened and synchronously generates steam when passing through the second water-storing sound-insulating cotton block 52. When the amount of steam is large, part of the steam passes through the steam channel 12 from the top of the steam buffer block 10, and part of the steam will pass through a plurality of buffer holes 11 on the steam buffer block 10, thereby achieving the effect of steam buffering. The steam is then sprayed to the ambiance through a plurality of steam columns 6, and the steam direction is changed through the isolation guide ports 9 on the steam column isolation covers 8 to spray to the comb tooth structure in the middle of the upper end face of the flexible isolation plate 7, thereby realizing the steam humidification function of the hair-straightening comb.

[0088] Compared with the prior art, the steam generator for hair-straightening combs of the present disclosure has the following advantages.

[0089] An embodiment of the present disclosure provides a steam generator for hair-straightening combs, including an evaporation assembly and a heating plate assembly. The evaporation assembly includes an evaporation water tank and a water injection pipe. The evaporation water tank is provided with an evaporation groove and an air-spraying groove connected to the evaporation groove. The heating plate assembly is connected to the side of the evaporation water tank away from the evaporation assembly. A first water-storing sound-insulating cotton block is provided in the evaporation groove, and the first water-storing sound-insulating cotton block is located between the water injection pipe and the bottom of the evaporation groove, such that the position of the first water-storing sound-insulating cotton block corresponds to the position of the water injection pipe extending into the evaporation groove, thus the water injection pipe extending into the evaporation groove can sink into the first water-storing sound-insulating cotton block located below the water injection pipe. When water is injected into the evaporation groove through the water injection pipe, the water flowing out of the water injection pipe will first contact the first water-storing sound-insulating cotton block under the water injection pipe, so as to diffuse the water evenly to the bottom of the evaporation groove through the first water-storing sound-insulating cotton block, thereby buffering the water injection and reducing the noise during the water injection. When high-temperature heating is performed at the lower end of the evaporation water tank through the heating plate assembly, the moisture in each part of the first water-storing sound-insulating cotton block can fully contact the bottom of the evaporation groove to prevent the heating plate from being in a high temperature and local low-temperature environment for a long time and being easily damaged. In addition, since the interior of the water-storing sound-insulating cotton block is a loose and porous structure, the moisture is fully contacted in the first water-storing sound-insulating cotton block during the evaporation process, such that steam can be generated more evenly, excessive steam generation can be prevented, and the noise generated during water evaporation can be effectively reduced.

[0090] In the embodiment of the present disclosure, the first water-storing sound-insulating cotton block is arranged to be higher than one end of the water injection pipe close to the evaporation groove and lower than the highest point of the evaporation groove, such that at least a part of the water injection pipe is directly immersed in the first water-storing sound-insulating cotton block, which is more conducive to the full contact between the water flowing out of the water injection pipe and the first water-storing sound-insulating cotton block. This avoids the water flowing out of the water injection pipe rushing out of the first water-storing sound-insulating cotton block and directly impacting the evaporation groove, thereby further reducing the possibility of noise generation.

[0091] In the embodiment of the present disclosure, a steam port is provided on the water tank base, such that the steam passage rate and the steam passage amount per unit time between the evaporation groove and the air-spraying groove can be controlled through the steam port, thereby avoiding the situation where the steam flows into the air-spraying groove too fast or too slow or the steam flows into the air-spraying groove too much or too little.

[0092] In the embodiment of the present disclosure, a plurality of steam columns are arranged on the water tank cover, and the positions of the plurality of steam columns correspond to the positions of the air-spraying groove, such that the steam in the air-spraying groove directly enters the comb tooth structure through the steam columns, thereby making the steam efficiency higher.

[0093] In the embodiment of the present disclosure, a plurality of steam columns are arranged at intervals according to a preset arrangement, and the total length of the plurality of steam columns is less than or equal to the length of the air-spraying groove, such that the plurality of steam columns are arranged to match the shape and size of the air-spraying groove, avoiding the accumulation of steam in the air-spraying groove and saving the production cost.

[0094] In the embodiment of the present disclosure, the steam port is arranged at one end of the evaporation groove away from the water injection pipe, such that there is a certain distance between the water injection pipe and the steam port, thereby reserving time for the first water-storing sound-insulating cotton block to absorb the water flowing out of the water injection pipe, so as to prevent the water flowing into the water injection pipe from directly flowing into the air-spraying groove through the steam port.

[0095] In the embodiment of the present disclosure, a second water-storing sound-insulating cotton block is arranged at one end of the evaporation groove away from the water injection pipe. The water in the first water-storing sound-insulating cotton block contacts with the bottom of the evaporation groove to evaporate. The generated steam passes through the upper surface of the second water-storing sound-insulating cotton block to moisten the second water-storing sound-insulating cotton block and evaporates simultaneously. After the steam is sprayed from the air-spraying groove, the steam contacts with the upper surface of the second water-storing sound-insulating cotton block and condenses into water droplets again, thereby achieving effective steam buffering when the steam generator for hair-straightening combs is just turned on.

[0096] In the embodiment of the present disclosure, the first water-storing sound-insulating cotton block and the second water-storing sound-insulating cotton block are both arranged below the highest point of the evaporation groove to prevent the internal gas of the first water-storing sound-insulating cotton block and the second water-storing sound-insulating cotton block from expanding and increasing in volume when water evaporates, thereby ensuring normal steam production.

[0097] In the embodiment of the present disclosure, an isolation blocking bar is arranged between the first water-storing sound-insulating cotton block and the second water-storing sound-insulating cotton block, and the steam port is connected to the air-spraying groove and the second groove, such that the evaporation groove is separated by the isolation blocking bar to form the first groove and the second groove isolated from each other, thereby preventing the clean water flowing in from the water injection pipe from directly flowing into the air-spraying groove through the steam port and causing water accumulation.

[0098] In the embodiment of the present disclosure, the isolation blocking bar is arranged to be higher than the first water-storing sound-insulating cotton block and the second water-storing sound-insulating cotton block, and lower than the highest point of the evaporation groove, so as to avoid the connection between the bottoms of the first groove and the second groove, thereby avoiding direct contact between the first water-storing sound-insulating cotton block and the second water-storing sound-insulating cotton block, and preventing a large amount of water from the first groove from entering the second groove, resulting in the second water-storing sound-insulating cotton block being unable to achieve the evaporation buffer effect.

[0099] In the embodiment of the present disclosure, a blocking block is arranged on the side of the water tank cover away from the steam column, and the blocking block is aligned with the pipe mouth of the water injection pipe extending into the first groove, so as to further prevent the water in the water injection pipe from directly rushing into the second groove, and prevent the water from directly flowing into the air-spraying groove through the steam port to cause water accumulation, thereby improving the control of actual water outflow from the water injection pipe.

[0100] In the embodiment of the present disclosure, the first channel and the second channel are combined to form a steam channel, which makes the distribution range of the steam channel wider, such that the steam can pass more evenly from the top of the first water-storing sound-insulating cotton block to the top of the second water-storing sound-insulating cotton block, preventing uneven steam distribution.

[0101] In the embodiment of the present disclosure, the blocking block and the isolation blocking bar are staggered, such that the steam on the top of the first water-storing sound-insulating cotton block can more easily enter the top of the second water-storing sound-insulating cotton block, thereby preventing the steam from accumulating at the angle between the blocking block and the water tank cover.

[0102] In the embodiment of the present disclosure, a flexible isolation plate is arranged on a side of the evaporation assembly away from the heating plate assembly. A plurality of steam column isolation covers are arranged on one side of the flexible isolation plate, and each steam column isolation cover correspondingly covers a steam column, thereby achieving heat insulation of the evaporation assembly through the flexible isolation plate and the steam column isolation cover, preventing the comb tooth structure from being overheated and scalding the user.

[0103] In the embodiment of the present disclosure, the isolation guide port faces the side of the flexible isolation plate where the steam column isolation cover is not arranged, which can spray steam accurately onto the comb tooth structure in the middle of the upper end face of the flexible isolation plate, thereby realizing directional steam spraying and effectively preventing steam overflow and causing burns.

[0104] In the embodiment of the present disclosure, a plurality of buffer holes are provided on the steam buffer block, and the plurality of buffer holes are arranged at intervals, such that when the amount of steam is small, the steam passes from the upper ends of the plurality of steam buffer blocks and enters the air-spraying groove through the steam port, and the steam is then sprayed through the plurality of steam columns. When the amount of steam is large, part of the steam passes from the top of the steam buffer block through the steam channel, and part of the steam passes through the plurality of buffer holes on the steam buffer block, thereby achieving the effect of steam buffering and preventing excessive steam from passing through the steam port at the same time and resulting in a large amount of steam sprayed and causing burns.

[0105] In the embodiment of the present disclosure, the connecting plate is connected to the side of the water tank base away from the evaporation groove by a plurality of locking screws, such that a firm connection between the heating plate assembly and the evaporation assembly can be achieved, while also being easy to disassemble. In addition, the heating plate is arranged between the connecting plate and the water tank base, such that the clean water at the bottom can be fully heated and evaporated by the heating plate, making the steam volume more stable.

[0106] In the embodiment of the present disclosure, two limit blocks are arranged on the side of the water tank base away from the evaporation groove, such that the heating plate is clamped between the two limit blocks to limit the heating plate and prevent the heating plate from shifting and affecting the heating effect.
