Description

Technical Field

[0001] This utility model relates to the technical field of hair care, and in particular to a steam hair styling device. Background Technology

[0002] In the hair care industry, steam hair styling tools have become one of the mainstream hair styling tools due to their advantages of softening the hair cuticle with steam and reducing high-temperature damage to the hair. The core working principle of traditional steam hair styling tools is usually to heat the water in the water tank or water pipe through a heating element, causing the water to vaporize and generate steam. The steam is then delivered to the hair surface through the steam outlet, and the styling effect is achieved in conjunction with the shaping action of the heated plates.

[0003] However, existing steam hair styling devices have the following shortcomings in actual use: The steam generation mechanism of traditional steam hair styling devices mostly adopts the "fixed power heating - passive vaporization" mode: the heating element usually operates at a constant power, or only sets a fixed heating power according to the preset level (such as "low temperature", "medium temperature" and "high temperature"). The water supply flow of the water storage system to the heating area is usually achieved by using a water pipe with a fixed orifice to achieve quantitative supply, without establishing a linkage control logic between temperature and water supply. When a hair styling tool is turned on from standby or switched from a low to a high setting, the heating element needs to raise its temperature to the target vaporization temperature. However, the water flow rate is fixed at this time. When water comes into contact with the heating element, which has not reached its vaporization temperature, it cannot vaporize in time. It often takes a while to generate stable steam, which seriously affects the user's efficiency. Secondly, during continuous use, the temperature of the heating element will fluctuate due to changes in ambient temperature and heat dissipation due to hair strands. When the temperature is higher than the target value, the fixed flow rate of water will rapidly over-vaporize, resulting in an excessive amount of steam being ejected at once, which can easily cause burns. When the temperature is lower than the target value, the water cannot fully vaporize, resulting in a "dripping" phenomenon. This not only fails to provide hair care but also affects the shaping effect of the flat iron on the hair. Furthermore, due to the mismatch between the water supply and the heating temperature, some water molecules can only reach a preheated state and cannot fully vaporize. The resulting "semi-steam" contains a large number of liquid water droplets. When these water droplets adhere to the surface of the hair strands, they severely reduce the styling durability of the hair styling tool. In view of this, the steam hair styling device of this application is hereby proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a steam hair stylist that can adjust the temperature in real time and adjust the steam flow accurately according to the user's usage status, thus avoiding the problems of slow steam generation, instability and poor vaporization effect.

[0005] The objective of this utility model is achieved through the following technical solution: A steam hair styling device, comprising: The housing includes two outer shells, one end of which is hinged to each other; and A steam assembly includes a control board, a water supply component, a first heating component, and a second heating component. The control board and the second heating component are both disposed within one housing, and the water supply component and the first heating component are both disposed within another housing. The two housings respectively drive the first heating component and the second heating component to move closer together to clamp the hair. The first heating component includes a first clamping plate, a heating plate, and a sensing strip. The first clamping plate is disposed on the housing, and the heating plate and the sensing strip are disposed on the first clamping plate at intervals. One end of the water supply component clamps the heating plate together with the first clamping plate. The first clamping plate has several air holes, each of which communicates with the water supply component. The heating plate, the sensing strip, and the water supply component are all electrically connected to the control board so that the heating plate heats the water supplied by the water supply component.

[0006] Optionally, the first clamping plate is provided with a partition strip, which divides the first clamping plate into a first embedding groove and a second embedding groove. The sensing strip and the heating plate are respectively disposed in the first embedding groove and the second embedding groove, and each of the air holes is opened on the partition strip.

[0007] Optionally, the first clamping plate is provided with an elongated groove, the two ends of which extend to the two ends of the first clamping plate, and each of the air holes communicates with the elongated groove.

[0008] Optionally, the water supply component includes a water tank, a water pump, and a water delivery plate. The water tank and the water pump are both housed within the outer casing. The water pump is connected to both the water tank and the water delivery plate. The control board is electrically connected to the water pump. The water delivery plate is mounted on the first clamping plate. The water delivery plate and the first clamping plate together clamp the heating plate, and each of the air holes is connected to the water delivery plate.

[0009] Optionally, the water conveying plate includes an upper plate and a lower plate. The lower plate has a continuously curved water groove. The upper plate is disposed on the partition strip, and the lower plate is disposed on the upper plate, so that the upper plate and the lower plate together form a continuously curved S-shaped channel. The two ends of the S-shaped channel are respectively connected to the water pump and each of the air holes.

[0010] Optionally, the second heating element includes a second clamping plate with a groove. Multiple heating plates and sensing strips are provided, with each heating plate and sensing strip spaced apart within the groove.

[0011] Optionally, the width of the groove is greater than the width of the heating plate.

[0012] Optionally, the second heating element further includes a partition and a top plate. A boss is provided on the second clamping plate. The partition abuts against the heating plate, and the two sides of the top plate abut against the partition and the boss respectively, so that the top plate presses against the heating plate.

[0013] Compared with the prior art, the present invention has at least the following advantages: This utility model discloses a steam hair styling device. Firstly, both the first and second heating elements are equipped with heating plates and sensing strips. The sensing strips (NTC sensors) collect the temperature of the heating plates in real time and feed it back to the control board. The control board can independently adjust the power of each heating plate, achieving real-time and precise temperature control. Secondly, the water supply component includes a water pump and a water delivery plate. The water delivery plate has an S-shaped channel to extend the water flow heating path. The control board adjusts the water pump speed based on temperature data, precisely controlling the water flow rate to prevent dripping at low temperatures and excessive steam at high temperatures. Thirdly, the first clamping plate has a long groove, with air holes connected to the groove, resulting in a short steam transmission path and even diffusion to both ends of the first / second clamping plates. Thus, combined with coordinated temperature and flow rate control, the problems of slow steam generation, unstable output, and poor vaporization are solved. Attached Figure Description

Detailed Implementation

[0017] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0018] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "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 this embodiment of the invention according to the specific circumstances.

[0021] like Figures 1 to 6As shown, in one embodiment, a steam hair stylist 1 includes a housing and a steam assembly. The housing includes two outer shells, one end of which is hinged to each other. The steam assembly includes a control board 20, a water supply component 21, a first heating component 22, and a second heating component 23. The control board 20 and the second heating component 23 are both housed in one outer casing, while the water supply component 21 and the first heating component 22 are both housed in another outer casing. The two outer casings respectively drive the first heating component 22 and the second heating component 23 to move closer to each other to clamp the hair together. The first heating component 22 includes a first clamping plate 220, a heating plate 221, and a sensing strip 222. The first clamping plate 220 is disposed on the outer casing. The heating plate 221 and the sensing strip 222 are disposed on the first clamping plate 220 at intervals. One end of the water supply component 21 clamps the heating plate 221 together with the first clamping plate 220. The first clamping plate 220 has several air holes 2200, each of which is connected to the water supply component 21. The heating plate 221, the sensing strip 222, and the water supply component 21 are all electrically connected to the control board 20 so that the heating plate 221 heats the water supplied by the water supply component 21.

[0022] It should be noted that the two outer shells are hinged at one end, forming a V-shaped, rotatable opening and closing structure. For ease of description, the two outer shells are defined as the first outer shell 10 and the second outer shell 11, respectively. The hinged end of the two outer shells is defined as the handle, and the ends of the two outer shells that are far apart are defined as the clamping part. The control board 20 is a circuit board integrating an intelligent control chip. The control board 20 is located inside the handle of the second outer shell 11, the second heating element 23 is located on the clamping part of the second outer shell 11, the water supply element 21 is located inside the handle of the first outer shell 10, and the first heating element 22 is located on the clamping part of the first outer shell 10. Thus, when the two outer shells rotate around the hinged end to the closed state, they will respectively drive the first heating element 22 and the second heating element 23 to move closer together to clamp the hair.

[0023] It should be noted that the first heating element 22 includes a first clamping plate 220, a heating plate 221, and a sensing strip 222. The first clamping plate 220 is disposed on the first outer shell 10, and one side of the first clamping plate 220 protrudes from the side of the first outer shell 10 closest to the second outer shell 11. The heating plate 221 and the sensing strip 222 are both disposed on the side of the first clamping plate 220 away from the second outer shell 11, and there is a gap between the heating plate 221 and the sensing strip 222. Further, the water supply element 21 is disposed inside the first outer shell 10, and one end of the water supply element 21 is connected to the side of the first clamping plate 220 closest to the heating plate 221. Further, the first clamping plate 220 is provided with a plurality of air holes 2200, and the air holes 2200 are arranged in a straight line. When one end of the water supply element 21 and the first clamping plate 220 clamp the heating plate 221 together, each air hole 2200 is connected to one end of the water supply element 21. Thus, when the heating plate 221 is powered on, it heats the water supplied in the water supply component 21, allowing the vaporized steam to be ejected from the vents 2200, reducing steam loss during transmission and improving vaporization efficiency. Furthermore, a sensing strip 222 is disposed within the first clamping plate 220 and close to the heating plate 221. The sensing strip 222 is an NTC sensor (negative temperature coefficient thermistor sensor), and the heating plate 221 is a PTC heater (positive temperature coefficient thermistor heater). Both the sensing strip 222 and the heating plate 221 are electrically connected to the control board 20, enabling the sensing strip 222 to monitor the temperature change of the heating plate 221 in real time and feed the monitored temperature data back to the control board 20. The water supply component 21 is also electrically connected to the control board 20, allowing the control board 20 to control the heating power of the heating plate 221 in real time according to temperature changes, while simultaneously controlling the amount of water supplied by the water supply component 21. Thus, by electrically connecting the control board 20 with the heating plate 221, the water supply component 21, and the sensing strip 222, the sensing strip 222 can collect the temperature data of the heating plate 221 in real time and feed it back to the control board 20. The control board 20 can dynamically adjust the power of the heating plate 221 and the water supply of the water supply component 21 according to the temperature change. When the temperature of the heating plate 221 is lower than the vaporization threshold, the control board 20 reduces the water supply and increases the heating power to prevent unvaporized water from dripping directly. When the temperature is higher than the threshold, the water supply is increased and the heating power is maintained to ensure a continuous and stable output of steam, effectively avoiding the problems of slow steam generation, instability, and poor vaporization effect.

[0024] like Figures 3 to 4 As shown, in one embodiment, a spacer 2201 is provided on the first clamping plate 220, which divides the first clamping plate 220 into a first embedding groove and a second embedding groove. The sensing strip 222 and the heating plate 221 are respectively disposed in the first embedding groove and the second embedding groove, and each air hole 2200 is opened on the spacer 2201.

[0025] It should be noted that a spacer 2201 extending along its length is integrally formed on one side of the first clamping plate 220 facing the interior of the first outer shell 10. The spacer 2201 protrudes vertically from the surface of the first clamping plate 220 and divides the corresponding area of ​​the first clamping plate 220 into two independent first embedding grooves and a second embedding groove. The sensing strip 222 is embedded in the first embedding groove, and the outer wall of the sensing strip 222 is tightly fitted with the inner bottom wall of the first embedding groove. The heating plate 221 is interference-fitted. The heating plate 221 is embedded in the second embedding groove, and the outer wall of the heating plate 221 is closely fitted with the inner bottom wall of the second embedding groove. At the same time, each air hole 2200 is opened on the spacer 2201, and each air hole 2200 is distributed at intervals along the length direction of the spacer 2201. The air hole 2200 penetrates the thickness direction of the spacer 2201, one end of which is connected to the internal channel of the water outlet end of the water supply component 21, and the other end extends to the surface of the first clamping plate 220 near the second heating component 23 to form a steam outlet channel. Thus, the first and second embedding slots formed by the partition strip 2201 can accurately position and fix the sensing strip 222 and the heating plate 221, ensuring that the sensing strip 222 always maintains a set distance from the heating plate 221. This not only ensures the accuracy of the sensing strip 222's temperature detection of the heating plate 221, but also prevents electromagnetic interference caused by contact between the two, thus improving temperature control accuracy. The vent 2200 is opened on the partition strip 2201, allowing steam to be directly discharged from the partition strip 2201 to the hair clamping area, shortening the steam transmission path, reducing heat loss of steam during transmission, and preventing steam from condensing into water due to an excessively long path, further improving the vaporization effect.

[0026] like Figures 1 to 4 As shown, in one embodiment, a long groove 2202 is provided on the first clamping plate 220, and the two ends of the long groove 2202 extend to the two ends of the first clamping plate 220 respectively, and each air hole 2200 is connected to the long groove 2202.

[0027] It should be noted that a long groove 2202 is formed on the surface of the first clamping plate 220 near the second heating element 23. The long groove 2202 is formed along the length of the first clamping plate 220 and connects to the opposite ends of the first clamping plate 220. Furthermore, each vent 2200 is formed on the spacer 2201 and extends in a straight line to the surface of the first clamping plate 220 near the second heating element 23, and each vent 2200 is connected to the long groove 2202. When the two outer shells rotate around the hinge end to the closed state, they respectively drive the first heating element 22 and the second heating element 23. When the second heating elements 23 come close together to clamp the hair, the second heating elements 23 and the long groove 2202 together form a steam channel that communicates with the air holes 2200. In this way, the long groove 2202 runs through the entire length of the first clamping plate 220 and communicates with all the air holes 2200, so that the vaporized steam is evenly diffused in the long groove 2202, ensuring that the steam concentration is consistent throughout the entire length of the first clamping plate 220. This avoids the problem of "no steam" or "thin steam" at the end of the first clamping plate 220, allowing all parts of the hair to be evenly contacted with steam, thus improving the consistency of hair care and styling effects.

[0028] like Figures 1 to 4 As shown, in one embodiment, the water supply component 21 includes a water tank 210, a water pump 211, and a water conveying plate 212. The water tank 210 and the water pump 211 are both disposed in a housing. The water pump 211 is connected to the water tank 210 and the water conveying plate 212 respectively, and the control board 20 is electrically connected to the water pump 211. The water conveying plate 212 is disposed on the first clamping plate 220. The water conveying plate 212 and the first clamping plate 220 together clamp the heating plate 221, and each air hole 2200 is connected to the water conveying plate 212.

[0029] It should be noted that the water tank 210 and the water pump 211 are both fixedly installed inside the hand-held part of the first outer shell 10 (the water tank 210 is located near the end of the outer shell, and the water pump 211 is set next to the water tank 210). The water inlet of the water pump 211 is sealed and connected to the water outlet of the water tank 210 through a silicone water pipe, and the water outlet of the water pump 211 is sealed and connected to the water inlet of the water supply plate 212 through another silicone water pipe. The water supply plate 212 is long and strip-shaped and its size is adapted to the first clamping plate 220. The water supply plate 212 is fixedly installed on the side of the first clamping plate 220 away from the second heating element 23 (that is, the side of the first clamping plate 220 facing the inside of the first outer shell 10), and the water supply plate 212 and the first clamping plate 220 together clamp and fix the heating plate 221 (the heating plate 221 is clamped between the water supply plate 212 and the first clamping plate 220).

[0030] like Figures 3 to 4As shown, in one embodiment, the water conveying plate 212 includes an upper plate 2120 and a lower plate 2121. The lower plate 2121 has a continuously curved water groove 2122. The upper plate 2120 is disposed on the partition strip 2201, and the lower plate 2121 is disposed on the upper plate 2120, so that the upper plate 2120 and the lower plate 2121 together form a continuously curved S-shaped channel. The two ends of the S-shaped channel are respectively connected to the water pump 211 and each air hole 2200.

[0031] It should be noted that the water supply plate 212 includes an upper plate 2120 and a lower plate 2121. The lower plate 2121 has a continuously curved water channel 2122. The upper plate 2120 is set on the first clamping plate 220, and the lower plate 2121 is sealed on the upper plate 2120, so that the upper plate 2120 and the lower plate 2121 together form a continuously curved S-shaped channel. One end of the S-shaped channel is sealed to the outlet of the water pump 211 through a silicone water pipe, so that the water pump 211 supplies water to the S-shaped channel. The other end of the S-shaped channel is sealed to each air hole 2200 on the spacer 2201 of the first clamping plate 220. The water pump 211 is electrically connected to the control board 20 set in the hand-held part of the second housing 11 through a wire. The signal output terminal of the control board 20 is connected to the drive module of the water pump 211, forming an electrical control circuit for the start-stop and speed regulation of the water pump 211. In this way, the water supply plate 212 and the first clamping plate 220 together clamp the heating plate 221, which not only achieves the fixed installation of the water supply plate 212, but also enhances the installation stability of the heating plate 221. At the same time, the curved area of ​​the S-shaped channel corresponds completely to the heating area of ​​the heating plate 221, so that the water flow in the channel can fully contact the heat conducted by the heating plate 221, causing the water inside to be heated and vaporized, and can be sprayed out from each air hole 2200. Thus, the continuous curved structure of the S-shaped channel significantly extends the flow path of water within the water delivery plate 212, increasing the heating time of the water by the heating plate 221. The water can more fully absorb the heat from the heating plate 221, completing preheating or even initial vaporization in advance. This avoids insufficient vaporization and dripping caused by insufficient heating time after the water directly enters the vents 2200, significantly improving the vaporization effect. Furthermore, the S-shaped channel acts as a buffer and pressure stabilizer for the water flow, preventing uneven flow velocity due to pressure fluctuations when the water pump 211 supplies water. This ensures a stable flow velocity, making the steam output of each vent 2200 consistent and avoiding unstable steam output. In addition, the precise correspondence between the S-shaped channel and the heating area of ​​the heating plate 221 allows the heat from the heating plate 221 to be efficiently transferred to the water flow within the channel, reducing heat loss and improving energy utilization. Combined with the adjustment of the water pump 211 speed by the control plate 20, the timeliness and stability of steam generation are further optimized, effectively avoiding the problem of slow steam generation.

[0032] like Figure 2 , Figures 5 to 6As shown, in one embodiment, the second heating element 23 includes a second clamping plate 230, on which a groove 231 is provided. Multiple heating plates 221 and sensing strips 222 are provided, and a heating plate 221 and a sensing strip 222 are spaced apart in the groove 231.

[0033] It should be noted that the second heating element 23 includes a second clamping plate 230 that is structurally adapted to the first clamping plate 220. The second clamping plate 230 is fixedly installed on the inner side of the clamping part of the second outer shell 11 (opposite to the first clamping plate 220). A long strip-shaped groove 231 is provided on the working surface (i.e. the hair clamping surface) of the second clamping plate 230 away from the first clamping plate 220 along its length direction. Multiple heating plates 221 and sensing strips 222 are provided. The width of the groove 231 is greater than the width of the heating plate 221. A heating plate 221 and a sensing strip 222 are spaced apart in the groove 231, and the heating plate 221 and the sensing strip 222 are tightly fitted to the inner bottom wall of the groove 231. At the same time, each heating plate 221 is electrically connected to the control board 20 in the hand-held part of the second housing 11 through a wire, and each sensing strip 222 is also electrically connected to the control board 20 through a wire. The position of the groove 231 of the second clamping plate 230 corresponds one-to-one with the position of the heating plate 221 and the sensing strip 222 of the first clamping plate 220, ensuring that when the two housings are closed, the heating plate 221 and the sensing strip 222 of the second heating element 23 can work together with the corresponding parts of the first heating element 22 to act on the hair. Thus, both the first heating element 22 and the second heating element 23 are equipped with heating plates 221 and sensing strips 222. This ensures that when the two outer shells rotate around the hinge end to a closed state to drive the first heating element 22 and the second heating element 23 to clamp the hair together, the hair is heated evenly, reducing hair damage caused by localized high temperatures. (For example, when the heating plate 221 on the first heating element 22 is working, the heating plate 221 on the second heating element 23 is not working. This would cause the first clamping plate 220 and the second clamping plate 230 to come close to each other to clamp the hair together, and the hair on the first clamping plate 220 would be partially heated.) Heat will be quickly conducted to the second clamping plate 230, thereby affecting the efficiency of the heating plate on the first clamping plate 220 in heating water, and will also cause temperature differences on both sides of the hair, affecting the hair styling effect; moreover, each heating plate 221 is equipped with an independent sensing strip 222, which can collect the temperature data of the corresponding heating plate 221 in real time and feed it back to the control board 20. The control board 20 can independently adjust the power for each heating plate 221, further improving the temperature control accuracy, avoiding the failure of the whole heating due to the failure of a single heating plate 221, and enhancing the working stability of the steam hair stylist 1.

[0034] It should be noted that the second clamping plate 230 is also provided with an air groove 232 that matches the long groove 2202 on the surface near the first clamping plate 220. When the two shells are closed to drive the first clamping plate 220 and the second clamping plate 230 to move closer to each other to clamp the hair together, the air groove 232 and the long groove 2202 together form a steam channel, so that the steam can be evenly diffused to both ends of the first clamping plate 220 / second clamping plate 230.

[0035] like Figures 5 to 6 As shown, in one embodiment, the second heating element 23 further includes a partition 233 and a top plate 234. A boss 235 is provided on the second clamping plate 230. The partition 233 abuts against the heating plate 221. The two sides of the top plate 234 abut against the partition 233 and the boss 235 respectively, so that the top plate 234 presses against the heating plate 221.

[0036] It should be noted that, in addition to the second clamping plate 230, heating plate 221, and sensing strip 222, the second heating element 23 also includes a spacer 233 and a top plate 234. The second clamping plate 230 has two integrally formed protrusions 235 on the side away from the hair clamping surface (i.e., the side facing the inside of the second outer casing 11). The spacer 233 is made of high-temperature resistant insulating material, is thin, and its size is adapted to the heating plate 221. A spacer 233 is fitted to each side of the heating plate 221 away from the inner bottom wall of the groove 231. The edge of the spacer 233 is flush with... The edges of the heating plate 221 are aligned to ensure full contact between the partition 233 and the heating plate 221. The top plate 234 is made of an elastic material and has a "W"-shaped structure. One side of the top plate 234 is in close contact with the side of the partition 233 away from the heating plate 221, while the other side of the top plate 234 is in close contact with the side of the boss 235 facing the partition 233. Under its own elasticity, the top plate 234 generates a pressing force towards the partition 233, thereby firmly pressing the heating plate 221 against the inner bottom wall of the groove 231 through the partition 233. In this way, the top plate 234, through its contact with the boss 235, applies a uniform and stable pressing force to the heating plate 221 in the opposite direction, preventing the heating plate 221 from shifting or loosening due to long-term thermal expansion or vibration. This ensures that the heating plate 221 is always in close contact with the inner bottom wall of the groove 231, ensuring efficient heat transfer to the hair clamping surface and avoiding uneven heating caused by the loosening of the heating plate 221.
