Description

Technical Field

[0002] Hair straightener is one of the commonly used hairdressing tools, and the current hair straightener is not limited to the hair straightening function, but also has the effect of air-drying hair. For example, the patent document "CN220824038U, a hair dryer hair straightener" has the following main technical effects:

[0003] 1. The fan blows the wind into the second support plate through the wind guide louver, and the heater heats the wind, and then blows it out through the air supply grille to dry the hair between the upper clamping plate and the lower clamping plate with hot air. The synchronous straight hair heating plate heats the hair for straight hair care, and the hair is dried and heated at the same time. You can also choose not to start the heater, blow cold air, and air dry the hair, making hair care simpler and more convenient;

[0004] 2. An air guide diverter plate is provided inside the second support plate to make the hot air blow out evenly. Part of the wind passes through the hair and enters the air outlet grille, and is discharged from the air holes on the first clamping plate cover. Part of the wind is blocked by the hair and returns to be blown out through the air holes on the second clamping plate cover, thereby preventing heat accumulation caused by wind accumulation between the upper clamping plate and the lower clamping plate.

[0005] But at the same time, the airflow noise is loud and the hair drying is not ideal.

[0006] Here, a hair drying clamp structure which is different from the above structure and has a convection blowing function is proposed. Utility Model Content

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] Please refer to Figure 1-11 ;

[0041] The hair straightener of the utility model can combine the functions of hair straightening and hair curling with that of hair dryer, and can dry hair faster while reducing noise. Specifically, it comprises a clamp arm 1 and a clamp arm 2 which are arranged relatively and rotatably connected. An air inlet 7 is provided near the rotatable connection between the clamp arm 1 and the clamp arm 2, and the air inlet 7 is communicated with the internal air flow 8 of the hair straightener. The clamp arm 1 and the clamp arm 2 are provided with a hair straightening part 3 with the same structure on opposite sides. In one embodiment, any clamp arm has two hair straightening parts 3, and an air flow space is formed between the two hair straightening parts 3. An air flow generating part 4 is installed in the clamp arm 1. The air flow generating part 4 has two output ends, and each output end is respectively communicated with the air flow space formed between the corresponding two hair straightening parts 3. The air flow is transported to the air flow space formed between the corresponding two hair straightening parts 3 through the air flow generating part 4, and is blown out to the outside through the flow channel between the hair straightening part 3 and the outer shell of the clamp arm.

[0042] In another embodiment, each of the clamp arm 1 and the clamp arm 2 has a straight hair portion 3 that is arranged opposite to each other, and the airflow generating portion 4 has two output ends, which are respectively connected to the two straight hair portions. When the clamp arm 1 and the clamp arm 2 are closed, the two straight hair portions 3 are closed to form an airflow flow space, and the airflow is respectively transported to the straight hair portions 3 of the clamp arm 1 and the clamp arm 2 through the airflow generating portion 4, and is blown out to the outside through the flow channel between the straight hair portion 3 and the outer shell of the clamp arm.

[0043] For the parts not mentioned in this embodiment, reference may be made to the relevant structures in the prior art and will not be described in detail here;

[0044] Since the hair straightening parts 3 provided on the clamping arm 1 and the clamping arm 2 2 have the same structure, only the structure of one of the hair straightening parts 3 is described here, which specifically includes a shell 31. It should be noted that the shell referred to here can be a whole or a combination of multiple parts, as long as it can achieve the following functions, it is not limited here; at least one group of exhaust ports 32 is provided on the surface of the shell 31, two fixing plates 33 are symmetrically installed on the inner side of the shell 31, an air passage 34 is formed between at least one fixing plate 33 and the shell 31, and the air passage 34 is connected to the exhaust port 32, and an air cavity 35 is provided between the two fixing plates 33, and the airflow generating part 4 is connected to the air cavity 35. The air cavity 35 is provided with an exhaust groove 353 arranged obliquely, and the exhaust groove 353 faces the hair clamped by the left and right groups of fixing plates 33, so that the airflow flows to the air passage 34;

[0045] The hair straightening part 3 on the clamp arm 1 is provided with two fixing plates 33, and the hair straightening part 3 on the clamp arm 2 is also provided with two fixing plates 33 corresponding thereto. When in use, the fixing plates 33 on the clamp arm 1 fit with the fixing plates 33 on the clamp arm 2 to clamp and fix the hair, and the two opposite air cavities 35 are not in contact, but have a gap to form a space for air flow, and the exhaust slots 353 formed by the two air cavities 35 face oppositely;

[0046] During operation, high-speed gas is input into the two air chambers 35 through the air flow generating unit 4, and then blown out from the exhaust slots 353 of the two air chambers 35. Since the exhaust slots 353 are inclined, they have a guiding effect on the air flow. Moreover, there is a gap between the air chamber 35 and the two fixing plates 33, so that the air flow is blown out from the exhaust slots 353 and flows toward the corresponding exhaust port 32, forming a flow path for continuously performing cold air or hot air drying on the hair surface clamped between the two sets of fixing plates 33. The flow path passes through the corresponding air channel 34 and then communicates with the outside through the corresponding exhaust port 32.

[0047] Furthermore, since the two exhaust slots 353 are directed in opposite directions, the outflowing high-speed airflows will converge in the space formed between the two wind cavities 35, collide and mix, thereby slowing down the flow of the airflow, making the airflow stay in the space longer, and at the same time increasing the pressure of the airflow here; in addition, part of the airflow will hit the outer wall of the wind cavity 35 and bounce back and forth multiple times, thereby increasing the drying effect of the air pressure on the hair.

[0048] In one embodiment, referring to Figure 5 , the exhaust port 32 is located on the side facing the exhaust slot 353, and the air flow can be transported to the outside quickly;

[0049] In another embodiment, referring to Figure 6 The exhaust port 32 is arranged with its back to the exhaust slot 353. At this time, the airflow needs to wait until the gas in the space is filled before it can be ejected from the exhaust port 32, which can extend the time the gas stays in the space.

[0050] Based on the above embodiment, the fixing plate 33 is a heating plate with a built-in heating element (such as a PCT heating element, which is already a prior art and will not be elaborated on in detail here), which can realize the curling, softening and straightening of the hair, and at the same time cooperate with the wind drying effect of the cold air or hot air flow path, that is, the two functions of the traditional straight hair curling plate and the hair dryer are integrated together, which can dry wet hair more quickly and perform hair care and styling.

[0051] like Figure 7 As shown, two convection air flows are formed in the gap between the two air chambers 35. When the fixing plate 33 is in the clamping state, a relatively closed air flow space is formed. The air flow pressure is greater than the external air pressure. The relatively greater air flow pressure is more conducive to hair drying. In order to make the air flow space relatively more closed, baffles 6 are also provided at both ends of the exhaust slots 353 of the two air chambers 35 in the longitudinal direction. When closed, the baffles 6 are relatively clamped.

[0052] Specifically, refer to Figure 8 When the left and right sets of fixing plates 33 clamp the hair, they will also pull relative to the hair. In order to avoid excessive pressure on the clamping arm 1 and the clamping arm 2 to clamp the hair, that is, the clamping arm is difficult to pull relative to the hair, an elastic member 37 is further provided between the fixing plate 33 and the inner wall of the shell 31, so that the fixing plate 33 can float up and down, which is conducive to the smooth pulling of the clamping plate relative to the hair. In addition, the edges of the fixing plate 33 on both sides are also designed with arc surfaces to facilitate sliding and protection.

[0053] Further expansion based on the above embodiment, refer to Figure 7 The two fixing plates 33 in the hair straightening part 3 form an air passage 34 with the outer shell 31, and two groups of exhaust ports 32 are provided on the surface of the outer shell 31, and the two groups of exhaust ports 32 correspond to the two air passages 34 respectively;

[0054] When in use, the relatively arranged fixing plates 33 clamp and fix the hair, and then the airflow enters the two wind chambers 35 respectively, and then is blown out obliquely from the two exhaust slots 353. Since several fixing plates 33 are in a closed state, the airflow is blocked from flowing forward, that is, the airflow is guided and divided into two flow paths to continue to flow forward. At the same time, part of the airflow will be blocked by the hair and enter the corresponding air channels 34, and finally blown out from the exhaust port 32 to the outside, while the other part of the airflow will pass through the hair and enter the other air channels 34, and finally blown out from the corresponding exhaust port 32 to the outside, so as to realize the curling, softening, straightening and shaping of the hair, and at the same time cooperate with the wind drying effect of the cold air or hot air flow path, that is, the two functions of the traditional straight hair curling plate and the hair dryer are integrated together, which can dry wet hair more quickly and perform hair care and styling.

[0055] It should be noted that the airflow is blown out obliquely from the exhaust slot 353, which has two advantages and solves two problems compared to vertical blowing or horizontal blowing along the flow path; if the airflow is blown out vertically, more air will penetrate the clamped hair, and at the same time will bring a lot of air flow noise, causing a bad auditory experience for the user; if the airflow is blown out horizontally along the flow path, the air flow noise is the lowest at this time, but more air will flow forward along the surface of the clamped hair, and the air volume penetrating the clamped hair will be reduced, and the hair drying effect will be relatively poor at this time; therefore, the airflow is blown out obliquely from the exhaust slot 353, compared to vertical blowing, the air flow noise will be reduced, and at the same time the air volume penetrating the clamped hair will be larger than the air volume when the airflow is blown out horizontally along the flow path, and the hair drying effect will be better.

[0056] In one embodiment of the present invention, the structure of the air cavity 35 may include a fixing portion 1 351 and a fixing portion 2 352, both of which are in an "L" shape. The fixing portion 1 351 and the fixing portion 2 352 are arranged opposite to each other, and the ends of the two parts are stacked up and down to form an exhaust groove 353. Preferably, the end of the fixing portion 1 351 is inclined, and the end of the fixing portion 2 352 is provided with a matching inclined surface. In addition, the inner side of the end of the fixing portion 1 351 and the outer side of the end of the fixing portion 2 352 are both designed with a curved surface, which is more conducive to airflow guidance and makes the airflow flow smoother. Figure 4 As shown, the exhaust slot 353 is located on one side of the wind cavity 35 closer to the fixing part 1 351. When the airflow flows out from the exhaust slot 353, it will flow toward the corresponding fixing part 2 352, so that the flow path is relatively longer. If the exhaust slot 353 is moved to the side of the fixing part 2 352, the airflow path will be relatively shorter, which will affect the effect of the wind flow on the hair.

[0057] The airflow generating part 4 in the utility model can directly generate hot air and then blow it into the air cavity 35. In this embodiment, a method of generating hot air is adopted. Specifically, a heating component 36 is arranged in the air cavity 35. The cold air blown out by the airflow generating part 4 is heated into hot air when passing through the heating component 36. Fig.11 In this embodiment, the heating component 36 includes a horizontal plate 361 arranged horizontally, and vertical plates 362 are inserted on both sides of the horizontal plate 361 to form a support frame. Such a design can adapt to a long strip heating chamber. A heating wire 363 is wound on the support frame. Each roll of the wound heating wire 363 contacts six fulcrums on the support frame, so that the enclosed space forms six heating channels. The same volume of gas can be divided into six streams for heating through the six heating channels. There are several perforations in the middle of the horizontal plate 361 (not shown in the drawings) to allow airflow to shuttle freely, and the airflow can pass through the heating wires 363 in an interlaced manner, so that the gas is heated more fully.

[0058] One embodiment of the airflow generating unit 4 of the utility model is shown in FIG. Fig. 9 and Fig.10 Specifically, it includes a three-way pipe body integrally formed of a soft material, one end of which forms a mounting portion 41, and the other two ends are air outlet portions 42, which are symmetrically arranged at intervals and extend in the opposite direction relative to the mounting portion 41; in other words, the opening of the mounting portion 41 faces one end, and the openings of the two air outlet portions 42 face the same direction, which is opposite to the opening of the mounting portion 41;

[0059] The mounting portion 41 is used to mount the fan 43, and the side wall of its inner cavity is in close contact with the outer periphery of the fan 43, and the air outlet end of the fan 43 corresponds to the air outlet portions 42 at both ends; the three-way pipe body in this embodiment can be made of silicone material. Assuming that the fan 43 is cylindrical, the inner cavity of the mounting portion 41 is also cylindrical. Further, the inner cavity diameter of the mounting portion 41 can be slightly smaller than the outer diameter of the fan 43. When the fan 43 is installed, the stretchability of the three-way pipe body is utilized to force the fan 43 into the inner cavity of the mounting portion 41. The friction force can make the side wall of the inner cavity and the outer peripheral wall of the fan 43 close together, and at the same time, a good airtight effect can be achieved; preferably, the length of the mounting portion 41 is greater than or equal to the length of the outer periphery of the fan 43; according to the prior art, the installation of the fan 43 and the air pipe should require a connector, and the utility model adopts such a design to omit the intermediate component, reduce the workload of object management, and at the same time improve the airtightness and prevent air leakage;

[0060] In the present embodiment, at least one support plate 44 extending along the direction of the air duct 34 is provided in the air outlet portion 42; when the two clamp arms are in the unfolded state, the two air outlet portions 42 are squeezed, and at this time the support portion can exert a reverse force to support its internal space. It should be noted that the support plate 44 is integrally formed with the tee pipe body, and under the action of the support plate 44, the compression deformation of the air outlet portion 42 is reduced, and the original caliber is basically maintained, so that the airflow generated by the fan 43 is basically unobstructed and passes smoothly. In addition, the design of the support plate 44 has the function of cutting and guiding the airflow to reduce noise.

[0061] In the embodiment of the utility model, a display screen 5 is provided on the surface of the clamp arm 1, and the display screen 5 is electrically connected to the internal controller. The current use status of the hair straightener can be displayed through the display screen 5.

[0062] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
