Description

Technical Field

[0001] The utility model relates to the technical field of hairdressing appliances, in particular to a heating structure of a hair straightener with a hot air outlet function. Background Art

[0002] In modern life, hair straighteners have become one of the important tools for people's daily care. Its portability, ease of use and high efficiency make people increasingly dependent on this small appliance. Chinese patent document CN220756795U discloses a hair straightener dryer with a blowing function for air drying hair. It can be seen from the relevant drawings that the blown air flow is directly lost from the air flow channel, and the flowing air is not fully utilized. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a hair straightener heating structure with hot air outlet function.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hair straightener heating structure with hot air outlet function, comprising two clamp arms hinged to each other at one end, at least one clamp arm having an inner arm flow channel inside, and the other ends of the two clamp arms can be opened or closed, characterized in that: the two clamp arms form an inter-arm flow channel in the closed position, the inter-arm flow channel is extended along the hair entry direction, and the two ends of the inter-arm flow channel respectively have an entry end and an exit end in the hair entry direction, the inter-arm flow channel is sequentially provided with an airflow drying section and an ironing plate straightening section from the entry end to the exit end, the inner wall surface of at least one of the clamp arms is provided with a fluid outlet on the airflow drying section, and the inner wall surfaces of the two clamp arms are provided with two heatable straightening plates opposite to each other on the ironing plate straightening section, at least one of which forms a branch flow channel for fluid to pass through between the inner wall surface of the clamp arm where the at least one clamp arm is located, and the flow path of the fluid flowing out of the branch flow channel is parallel to the horizontal center line.

[0005] The hair is dried three times with high drying efficiency. The hair is dried for the first time in the drying section, and dried for the second time in the straightening section when the hair is heated and straightened by the heatable hair straightening plate. The internal fluid takes away the heat of the heatable hair straightening plate through the diversion channel, and the reheated internal fluid performs a third drying process on the hair at the starting end, thereby making full use of the internal fluid to achieve a uniform heating effect. Secondly, the internal fluid takes away the heat of the heatable hair straightening plate, which reduces the temperature of the heatable hair straightening plate and prolongs the service life of the heatable hair straightening plate. Preferably, the hair inlet end has an air suction port for the external fluid to enter. By using the Bernoulli principle, the inter-arm flow channel can absorb the external fluid and mix the internal fluid ejected from the fluid outlet, so that the energy efficiency of the air is fully utilized to act on the hair. When used from the inlet of the external fluid 91, it is close to the hair root and scalp, thereby ensuring that the temperature of the side of the two clamping arms close to the hair root and scalp is relatively low, which can improve the comfort experience of the hair care user.

[0006] Preferably, the hair entry direction is perpendicular to the length direction of the clamp arm and parallel to the width direction of the clamp arm.

[0007] Preferably, the fluid outlet is close to the hair inlet and located on the upstream side of the fluid perpendicular to the center line, so as to maximize the use of the inner wall area of ​​the clamp arm to form a sufficiently long inter-arm flow channel, so that the fluid acts on the hair for a long time and the fluid utilization efficiency is high.

[0008] Preferably, the hair inlet is provided with a support rod, which is arranged to prevent hair from blocking the fluid outlet.

[0009] Preferably, the support rod is aligned parallel to the clamping arm, and the support rod comprises a clamping surface in contact with the hair, and the clamping surface is provided with limiting comb teeth.

[0010] Preferably, a suction hole is provided on the surface of the support rod which is perpendicular to the hair entry direction.

[0011] Preferably, an elastic member is provided between the hair straightening plate and the inner wall surface of the clamping arm, and the hair straightening plate can float relative to the inner wall surface of the clamping arm. Preferably, the elastic member is a spring or a silicone support member.

[0012] Preferably, a flow divider is provided on the inner wall surface of either or both of the clamping arms.

[0013] The beneficial effect of the utility model is that the hair straightener of the utility model has both the functions of hair dryer and hair straightener. Since the flow channel between the arms is extended along the direction of hair entry, the fluid can only flow to one side of the two clamping arms, that is, blow air along the direction of the hair ends, the hair will not be blown apart and can be straightened. At the same time, the high-pressure air flow acts on the hair to achieve straightening. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Embodiment 1:

[0032] See also Figure 1-12As shown, the utility model relates to a heating structure of a hair straightener with a hot air outlet function. When in use, the hair straightener has the functions of a hair dryer and a heated hair straightening plate at the same time, including an upper clamping arm 1 and a lower clamping arm 2. The upper clamping arm 1 and / or the lower clamping arm 2 have an inner arm flow channel inside. The hair straightener has a control element, a fan, a heating element, and a power supply electrically connected to each other. The fan generates power to create an internal negative pressure, and the outside air is sucked into the inner arm flow channel by the air inlet and then blown out by the air outlet. It is a prior art and will not be described in detail here. The rear ends of the upper clamping arm 1 and the lower clamping arm 2 are pivotally connected together, and the front ends of the upper clamping arm 1 and the lower clamping arm 2 can be opened or closed. When the upper clamp arm 1 and the lower clamp arm 2 are in the closed position, an inter-arm flow channel 3 extending in the direction of hair entry is formed between the upper clamp arm 1 and the lower clamp arm 2, and the inter-arm flow channel 3 has a hair entry end 31 and a hair exit end 32, and the inter-arm flow channel 3 is provided with an airflow drying section 33 and a hair straightening section 34 in sequence from the hair entry end 31 to the hair exit end 32. The hair entry end 31 has an air suction port 311 for external fluid 91 to enter. The inner wall surface of the upper clamp arm 1 and / or the lower clamp arm 2 has a fluid outlet penetrating the inter-arm flow channel 3 and the inner arm flow channel, and the fluid outlet is obliquely arranged on the inner wall surface of the clamp arm toward the hair exit end 32. Two heatable hair straightening plates facing each other are arranged on the inner wall surfaces of the upper clamping arm 1 and the lower clamping arm 2 on the straightening section 34 of the ironing plate. The heatable hair straightening plates are prior art. The heatable hair straightening plates soften, straighten or shape the hair by generating heat. The heatable hair straightening plates are connected to the inner surface of the clamping arm through an elastic member. When the heatable hair straightening plates clamp the hair and pull it, they can slide more easily, so that the heatable hair straightening plates can achieve a floating buffer function to prevent the hair from being clamped to death when the two clamping arms are gripped with excessive force. A diversion flow channel for fluid to pass through is formed between the heatable hair straightening plates and the inner wall surfaces of the clamping arms.

[0033] After the fluid is introduced into the inter-arm flow channel 3 through the fluid outlet of the clamp arm, the flow path of the fluid flows parallel to the horizontal center line (AB line in the figure) for a certain distance, and flows unilaterally toward the starting end 32 along the direction of the hair 7 entering. Or after the fluid is introduced into the inter-arm flow channel 3 through the fluid outlet of the clamp arm, the flow path of the fluid intersects with the horizontal center line, and flows unilaterally toward the starting end 32 along the direction of the hair 7 entering.

[0034] The inner wall surfaces of the upper clamp arm 1 and the lower clamp arm 2 are longitudinally extended with a mounting groove 81, and an elastic member 8 is arranged in the mounting groove 81. The heat-generating straightening plate is positioned on the elastic member 8, and each heat-generating straightening plate is aligned parallel to the clamp arm. In this embodiment, the elastic member 8 is a spring. The elastic member 8 can also be a silicone support member.

[0035] In this embodiment, a first arm inner flow channel 11 is provided inside the upper clamp arm 1, and a plurality of first fluid outlets 12 are provided on the inner wall surface of the upper clamp arm 1, and the first fluid outlets 12 penetrate the inter-arm flow channel 3 and the first arm inner flow channel 11, wherein the first fluid outlets 12 are obliquely arranged on the inner wall surface of the upper clamp arm 1, and a second arm inner flow channel 21 is provided inside the lower clamp arm 2, and a plurality of second fluid outlets 22 are provided on the inner wall surface of the lower clamp arm 2, and the second fluid outlets 22 penetrate the inter-arm flow channel 3 and the second arm inner flow channel 21. wherein the second fluid outlets 22 are obliquely arranged on the inner wall surface of the upper clamp arm 1.

[0036] In this embodiment, the upper clamping arm 1 is connected to the first heatable hair straightening plate 5 through an elastic member 8, and the lower clamping arm 2 is connected to the second heatable hair straightening plate 6 through an elastic member, so that the first heatable hair straightening plate 5 and the second heatable hair straightening plate 6 are suspended floatingly in the inter-arm flow channel 3. When the upper clamping arm 1 and the lower clamping arm 2 clamp the hair 7 and pull it, the elastic member 8 can provide a loose elastic force to prevent the hair 7 from being clamped to death when the two clamping arms are gripped with excessive force.

[0037] In order to fix the positions of the first heatable hair straightening plate 5 and the second heatable hair straightening plate 6 and prevent them from shaking, the inner wall surface of the upper clamping arm 1 is provided with a first clamping member 13, and the inner wall surface of the lower clamping arm 2 is provided with a second clamping member 23. The first heatable hair straightening plate 5 is disposed in the first clamping member 13, and the second heatable hair straightening plate 6 is disposed in the second clamping member 23.

[0038] The first clamping member 13 includes a plurality of first pillars 131 and a pair of first clamping rods 132. The plurality of first pillars 131 are divided into two rows and arranged on the inner wall surface of the upper clamping arm 1. A first flow channel opening 133 is provided between the first pillars 131 in each row, through which the fluid flows out of the first branch flow channel 134. The first clamping rods 132 are respectively arranged on the two rows of first pillars 131. The first clamping rods 132 clamp the first heatable hair straightening plate 5 in the middle, and have a limiting function.

[0039] Meanwhile, the second clamping member 23 includes a plurality of second pillars 231 and a pair of second clamping rods 232. The plurality of second pillars 231 are divided into two rows and are respectively arranged on the inner wall surface of the lower clamping arm 2. A second flow channel opening 233 is provided between the second pillars 231 in each row, through which the fluid can pass. The fluid flows out of the second branch flow channel 234 through the second flow channel opening 233. The second clamping rods 232 are respectively arranged on the two rows of second pillars 231. The second clamping rods 232 clamp the second heat-generating hair straightening plate 6 in the middle, and have a limiting function.

[0040] When the hair straightener dries the hair, the internal fluid 92 generated inside the first arm inner flow channel 11 and the second arm inner flow channel 21 flows out from the oblique first fluid outlet 12 and the second fluid outlet 22, and the internal fluid 92 is mixed with the external fluid 91 to form a mixed fluid 93 after flowing out, and the hair is dried for the first time in the airflow drying section 33; the first heatable hair straightening plate 5 and the second heatable hair straightening plate 6 will perform a second drying process on the hair while straightening the hair; wherein, the fluid after the first drying process meets the heatable hair straightening plate in the ironing plate straightening section 34 and flows into the first branch flow channel 134 and the second branch flow channel 234 respectively, and the fluid passes through the first branch flow channel 134 and the second branch flow channel 234, and the fluid will take away the heat of the heatable hair straightening plate, thereby reducing the temperature of the heatable hair straightening plate and extending the service life. Since the fluid is heated again after passing through the heatable hair straightening plate, the internal fluid flows out from the first flow channel opening 133 and the second flow channel opening 233 to perform a third drying process on the hair, thereby making full use of the internal fluid to achieve a uniform heating effect.

[0041] The specific principle of the reheating of the fluid in the straightening section 34 of the ironing plate is that the heat of one side of the heatable straightening plate is continuously taken away (because the temperature of the heatable straightening plate is generally set at 180 to 230 degrees Celsius, and the temperature is also adjusted to above 140 degrees Celsius in actual use, the heating combination in the flow channel of the clamping arm is generally used to heat the air by winding the heating wire, and the temperature is generally about 90 to 130 degrees Celsius. When the relatively low temperature air meets the high temperature area, the low temperature air will take away part of the heat), and a small part of the heat is taken away along the hair in the first heatable straightening plate. The gap between the straight hair plate 5 and the second heatable straight hair plate 6 passes through and takes away the heat between the upper and lower heatable straight hair plates. More fluid is rebounded at the first heatable straight hair plate 5 and the second heatable straight hair plate 6 and then flows through the first branch flow channel 134 and the second branch flow channel 234 with other main fluids, taking away part of the heat of the first heatable straight hair plate 5 and the second heatable straight hair plate 6, reducing the possibility that the internal temperature of the product will affect the product life due to excessive temperature. The heat taken away acts on the hair again after being blown out from the starting end 32. The heat dissipation of the heatable straight hair plate through the air may be beneficial to the possibility of the outermost circle of the hair bundle being scalded. The heat taken away by the heatable straight hair plate is not directly dissipated, but acts on the hair again. The hair is heated by the air, heated by the heatable straight hair plate, heated by the air, and air-smoothed, making full use of the energy efficiency of the air.

[0042] Embodiment 2:

[0043] like Figure 6As shown, the difference between the second embodiment and the first embodiment is that a first support rod 41 and a second support rod 42 are added to the hair entry end 31 of the upper clamp arm 1 and the lower clamp arm 2, and the support rods are mainly used to support the hair to prevent the hair from blocking the first fluid outlet 12 and the second fluid outlet 22. The first support rod 41 is arranged on the upper clamp arm 1, and the second support rod 42 is arranged on the lower clamp arm 2. At the same time, when the distance between the first support rod 41 and the second support rod 42 is smaller, the effect of the closed space is better, the air pressure in the inter-arm flow channel 3 can be strengthened, and the drying effect of the airflow on the hair can be increased.

[0044] Preferably, the surfaces of the first support rod 41 and the second support rod 42 are provided with limiting comb teeth 43. When the first support rod 41 and the second support rod 42 are close to each other to block the hair, the limiting comb teeth 43 evenly disperse the hair 7, so that the hair 7 is heated more evenly in the dryer.

[0045] When there are many hairs 7 between the limiting comb teeth 43 of the first support rod 41 and the second support rod 42, the suction of the external fluid 91 will be blocked, affecting the normal use of the air suction port 311. Preferably, a plurality of suction holes 44 are provided on the first support rod 41 and the second support rod 42. When the first support rod 41 and the second support rod 42 are close to each other and reach a closed state, even if the number of hairs 7 in the limiting comb teeth 43 blocks the gap between the first support rod 41 and the second support rod 42, the external fluid 91 can also enter the inter-arm channel 3 through the suction holes 44. The external fluid 91 is mixed with the internal fluid heated from the first arm inner channel 11 and the second arm inner channel 21 to cool down, which does not affect the cooling effect of the hair inlet 31, thereby reducing the possibility of scalding the hair roots and scalp, thereby improving the user's comfort experience to a certain extent.

[0046] Embodiment three:

[0047] like Fig. 9 As shown, in order to prevent hair from blocking the first fluid outlet 12 and the second fluid outlet 22, this embodiment 3 is another treatment solution relative to the embodiment 2. Different from the embodiment 1, in this embodiment 3, the airflow drying section 33 is divided into a first flow channel section 331 and a second flow channel section 332. The first flow channel section 331 extends and transitions to the ironing plate straightening section 34 through the second flow channel section 332. Compared with the embodiments 1 and 2, the first flow channel section 331 is narrower. Among them, the first fluid outlet 12 and the second fluid outlet 22 are both arranged in the second flow channel section 332.

[0048] When the hair straightener dries the hair, the first flow channel section 331 supports the hair, preventing the hair from falling, thereby preventing a large number of hairs 7 from affecting the normal use of the first fluid outlet 12 and the second fluid outlet 22 of the second flow channel section 332 .

[0049] Embodiment 4:

[0050] like Fig.11 As shown, the difference between the fourth embodiment and the first embodiment is that the outer surfaces of the upper clamping arm 1 and the lower clamping arm 2 of the fourth embodiment are provided with a modeling arc surface, and the user can wrap the hair 7 closely around the modeling arc surface when using it. The user can design the curly hair 7 according to his own needs to meet different styling requirements of the hair 7.

[0051] In order to promote the free upward and downward shuttle rebound of the one-way fluid, in the fourth embodiment, the first fluid outlet 12 and the second fluid outlet 22 are arc-shaped structures, and the fluid outlets of the arc-shaped structures are arranged toward the starting end 32 of the inter-arm flow channel 3. Among them, the inter-arm flow channel 3 is provided with a first flow divider 14 and a second flow divider 24, and the first flow divider 14 and the second flow divider 24 are respectively arranged on one side of the first fluid outlet 12 and the second fluid outlet 22, and the first flow divider 14 and the second flow divider 24 mainly make the internal fluid flow into multiple streams and penetrate the hair between the rebounding clamp arms more fully;

[0052] The first flow dividing member 14 and the second flow dividing member 24 are respectively disposed on one side of the first fluid outlet 12 and the second fluid outlet 22 , and their upper and lower positions may be staggered.

[0053] When the two clamp arms are clamped up and down and the product is in the start-up state, the heated internal fluid 92 in the arm inner flow channels of the upper clamp arm 1 and the lower clamp arm 2 flows out to the inter-arm flow channel 3 along the arc-shaped first fluid outlet 12 and the second fluid outlet 22, and part of the internal fluid 92 flows to the first flow diverter 14 and the second flow diverter 24 to be divided into multiple streams of fluid that bounce up and down in an interlaced manner to act on the hair between the two clamp arms, and finally merge into two streams of fluid that enter the first flow diverter channel 134 and the second flow diverter channel 234 respectively and flow out to the outside to act on the hair tips again;

[0054] The first branch flow channel 134 and the second branch flow channel 234 may be provided with both flow channels at the same time, or only one of the flow channels may be provided. When both flow channels are provided at the same time, the fluid flowing out of the outside may continue to act on the hair ends more fully.

[0055] Embodiment five:

[0056] like Fig.12As shown, the difference between the fifth embodiment and the fourth embodiment is that the fifth embodiment adopts a single-arm air outlet method, cancels the inner-arm flow channel, the first fluid outlet 12 and the first diverter 14 of the upper clamping arm 1, and only sets the inner-arm flow channel inside the lower clamping arm 2, retaining the second fluid outlet 22 and the second diverter 24.

[0057] When the two clamp arms are clamped up and down and the product is in the startup state, only the heated internal fluid 92 in the arm inner flow channel of the lower clamp arm 2 flows out from the arc-shaped second fluid outlet 22 to the inter-arm flow channel 3. The fluid flows from the second fluid outlet 22 to the inter-arm flow channel 3. The fluid passes through the second flow divider 24 and is divided into two streams. The first stream flows to the upper right along the inner wall surface of the upper clamp arm 1 and flows along the arc-shaped inner arm surface into the first flow divider 134. The second stream flows to the right along the inner wall surface of the lower clamp arm 2 and enters the second flow divider 234. In the fourth embodiment, the electric control device, heating components, etc. inside the upper clamp arm 1 are reduced, which saves the manufacturing cost while realizing the drying function, and makes the product lighter.

[0058] The first branch flow channel 134 and the second branch flow channel 234 may be provided with both flow channels at the same time, or only one of the flow channels may be provided. When both flow channels are provided at the same time, the fluid flowing out of the outside may continue to act on the hair ends more fully.

[0059] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
