Description

Technical Field

[0001] The utility model belongs to the technical field of hair care tools, and specifically relates to a hair straightener with a blowing function. Background Technique

[0002] A hair straightener is a commonly used hair styling tool. With the development of the times, existing hair straighteners are not only limited to the heating function but also have a blowing function, that is, they can blow-dry the hair during the straightening process, which can better straighten the hair. Different manufacturers have different understandings of the air outlet mode of the hair straightener. For example, the publicly disclosed technical literature "CN117958540A, a blowing hair straightener" or "CN114376316A, a hair straightener", etc. No matter which structure is adopted, the ultimate goal is to dry the hair faster and make it straighter.

[0003] Taking the above-mentioned publicly disclosed patent literature "CN117958540A, a blowing hair straightener" as an example for illustration, referring to its attached Figure 4 It can be seen the flow direction of the air flow passing through between the two clamping arms. This is a relatively novel air flow mode. However, according to in-depth research, if the air flow passes between the two clamping arms, it will be blocked by the hot plate to form a curved flow channel, which will cause the heat in the air flow to dissipate faster. Therefore, this technical solution proposes another air outlet mode to reduce energy loss. Content of the Utility Model

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0034] Please refer to Figure 1-11 ;

[0035] The straightening iron is one of the commonly used hair care tools at present. Its basic structure includes a pair of clamping arms 1 and 2 that are rotatably connected. The components that play the role of straightening hair are a straightening component 1 and a straightening component 2 installed on the opposite sides of the clamping arms 1 and 2. By closing the clamping arms 1 and 2, the straightening components 1 and 2 clamp the hair, and the straightening iron is moved along the straightening direction of the hair to complete the straightening operation. In the present utility model, the structures of the straightening component 1 and the straightening component 2 can be the same or different, but it is certain that at least one of the straightening component 1 and the straightening component 2 is provided with a heating component to heat the hair. In addition, both the straightening component 1 and the straightening component 2 are provided with air inlet ends 332, and an air outlet area 6 is provided on the same side. Both air inlet ends 332 are connected to an air flow generating component 5, and the air flow generating component 5 can be installed at the holding position of the clamping arm 1;

[0036] When in use, open the clamping arms 1 and 2, select a strand of hair and place it between the clamping arms 1 and 2, and then close the clamping arms 1 and 2 so that the straightening components 1 and 2 clamp the hair. The hair is heated by the cooperation of the straightening components 1 and 2. At the same time, the air flow generating component 5 is started to deliver air flows to the straightening components 1 and 2 respectively. Finally, the air flows are output from the air outlet areas 6 of the straightening components 1 and 2 respectively. Before the air flows are output from the air outlet areas 6, they will pass through the heating components and be heated into hot air flows, so the temperature of the air flows will rise. In this embodiment, the air outlet areas 6 are relatively inclined, so the air flows output from the two air outlet areas 6 will intersect in the edge area of the clamping arms 1 and 2. When in use, the hair is located between the two air outlet areas 6, so the two air flows sprayed out act on both sides of the hair respectively;

[0037] Among them, the straightening components 1 and 2 mainly play a role in guiding the air flow. Relevant air guiding structures can be set inside them to make the air flow output more smoothly. That is to say, after the air flow absorbs the heat in the straightening components, it is output from the air outlet area 6 and directly acts on the hair, minimizing the energy loss to a great extent. In addition, it can contact the hair in the edge area of the clamping arms 1 and 2, reducing the time for the air flow to stay outside, also playing a role in reducing energy loss. Moreover, the output air flow is not blocked by other components, and the flow rate is relatively fast, which can better dry the hair.

[0038] In the embodiment of the present utility model, a torsion spring 11 is provided at the end of the clamping arm 1.

[0039] The structures of the first straightening component 3 and the second straightening component 4 in this utility model are the same. That is to say, both airflows can output hot air. The two air outlet areas 6 are respectively close to the side edge positions of the first straightening component 3 and the second straightening component 4. Then, the heat generation at the edge position is relatively large. To avoid the temperature being too concentrated on one side, a first heat dissipation area 71 is provided on each of the first clamping arm 1 and the second clamping arm 2 close to the air outlet area 6. The air from the outside contacts the first straightening component 3 and the second straightening component 4, taking away the heat accumulated at their edges.

[0040] Since the structures of the first straightening component 3 and the second straightening component 4 are the same, the following will take the first straightening component 3 as an example for illustration;

[0041] Specifically, it includes a box body 31. The box body 31 can be an independent component installed on the first clamping arm 1 or a component integrally formed with the first clamping arm 1. A cover plate 32 is installed on the box body 31. The cover plate 32 can be an integrally formed structure with the box body 31 or an independent component fixedly installed. The cover plate 32 and the box body 31 enclose to form an air cavity 331. The air outlet area 6 is arranged on one side of the box body 31 and communicated with the air cavity 331. A first heating element 34 is arranged in the air cavity 331. The airflow generating assembly 5 inputs airflow into the air cavity 331. These airflows will stay in the air cavity 331 briefly and will be heated by the first heating element 34, thereby raising the temperature of the airflow. A hair clamping plate 35 is arranged on the side of the box body 31 away from the air outlet area 6. A floating member 36 is arranged between the hair clamping plate 35 and the inner surface of the first clamping arm 1, and the hair clamping plate 35 is connected to a second heating element 37;

[0042] During use, the two hair clamping plates 35 on the first straightening component 3 and the second straightening component 4 are pressed against each other to clamp the hair. At the same time, the hair clamping plate 35 is heated by the second heating element 37, directly acting on the hair to achieve the straightening effect. In addition, in this embodiment, an independent first heating element 34 is provided to heat the airflow, which can quickly raise the temperature of the airflow. Moreover, the independent heating element can be controlled separately, that is, more usage modes can be provided for users to choose.

[0043] Further, referring to Figure 3 And Figure 6, in the initial state, the upper surface of the hair clamp plate 35 is higher than the upper surface of the cover plate 32. Since a floating member 36 is provided between the hair clamp plate 35 and the box body 31, the two hair clamp plates 35 can float upward relative to the box body 31 when clamping hair, avoiding the situation of hair jamming. In addition, since a first heating member 34 needs to be provided in the air cavity 331, the air cavity 331 needs to have a relatively large space for installing the first heating member 34, while the space occupied by the hair clamp plate 35 is relatively small. The hair clamp plate 35 and the cover plate 32 are arranged at intervals to avoid jamming hair. That is, the box body 31 is divided into two parts, one part is used to form the air cavity 331, and the other part is used to install the hair clamp plate 35. The width of the surface of the cover plate 32 is B, and the width of the hair clamp plate 35 plus the gap is A, and the width B > width A, so that the air cavity 331 has enough width to install the first heating member 34.

[0044] In addition, when the hair has moisture, the two hair clamp plates 35 are used to clamp and fix the hair in a floating manner, and the moisture on the hair can be squeezed out during the process of dragging the hair straightener to move. One side of the cover plate 32 close to the hair clamp plate 35 is provided with an inclined surface. The bottom of the hair clamp plate 35 is hollowed out to form a guiding channel 38 with the inclined surface. A second heat dissipation area 72 is provided on one side of the first clamping arm 1 close to the guiding channel 38. During the process of dragging the hair straightener to move, external air can enter the guiding channel 38 from the second heat dissipation area 72, and can dissipate heat from the second heating member 37.

[0045] Based on the above structure, only the two hair clamp plates 35 in the first hair straightening assembly 3 and the second hair straightening assembly 4 clamp the hair, while the hair on the surface of the cover plate 32 is in a loose state. When two airflows are output, the hair is likely to fly randomly. To solve this problem, a hair clamping strip 391 is provided at a position on the surface of the cover plate 32 close to the air outlet area 6. The hair clamping strip 391 only has the function of clamping hair and can be made of metal or silica gel specifically. A way of fixing both ends of the hair is formed through the cooperation of the hair clamping strip 391 and the hair clamp plate 35;

[0046] Of course, the hair clamping strip 391 should be higher than the surface of the cover plate 32. In the initial state, the hair clamp plate 35 is higher than the hair clamping strip 391. When it is necessary to clamp and fix the hair, first, the two hair clamp plates 35 contact the hair. When clamping forcefully, the hair clamp plate 35 will move downward under the action of the floating member 36. At this time, the hair clamping strip 391 on the other side can contact and clamp the hair. To avoid the hair clamping strip 391 clamping the hair to death, it can be achieved by adjusting the force between the two hair clamp plates 35, that is, the floating amplitude.

[0047] Further, referring to Figure 6 , the position at the edge of the air outlet area 6 is relatively hot. To avoid heat conduction to the hair clamping strip 391, there is an isolation area 392 between the hair clamping strip 391 and the edge of the air outlet area 6.

[0048] In the prior art, air is input from an air flow generating component into a wind cavity. After the air pressure in the wind cavity rises, the gas is forced to be output from the air outlet area. In this way, the air flow cannot be output evenly and smoothly. If there is a heating element in the wind cavity, not all of the heated air flow can be output, but the heated air flow and the unheated air flow are mixed and output, which will also cause the temperature of the output air flow to be unstable. To solve the above problems, the present utility model also discloses a diversion and heat conduction structure, which can be applied to common hair care tools, such as straighteners and hair dryers, etc. Hereinafter, a straightener will be taken as an example for illustration;

[0049] Referring to Figure 11 , specifically, a wind guiding member 81 extending obliquely is provided in a box body 31. The wind guiding member 81, the box body 31 and a cover plate 32 enclose to form a wind cavity 331. One end of the box body 31 is provided with an air inlet end 332 communicating with the wind cavity 331, and the air inlet end 332 is connected to an air flow generating component 5. The width of one end of the wind cavity 331 close to the air inlet end 332 is C, and the width of the end far from the air inlet end 332 is D, and width C > width D.

[0050] The air flow enters the wind cavity 331 from the air inlet end 332. In actual application, a first heating element 34 is usually provided in the wind cavity 331, such as Figure 9 And Figure 10 The solution can well solve the problem of blocked air outlet, that is, a wind guiding member 81 is provided on the opposite side of the air outlet area 6. When the air flow enters the wind cavity 331 from the air inlet end 332 and encounters the first wave crest, the air flow is divided into two strands. One strand inclines towards the air outlet area 6 and flows out to the outside, and the other strand continues to advance along the trough surface of the wind guiding member 81 for a certain distance and then inclines towards the air outlet area 6 and flows out to the outside or reaches the second wave crest and is shunted again. This shunting and guiding technical feature does not occupy the space of the wind cavity 331 and the air flow is smooth with low noise. The wave crest and trough can be set in one group or multiple groups. When set in one group, it includes one wave crest and one trough. When set in multiple groups, there are at least two wave crests, and there is one trough between two adjacent wave crests. The vertical distance L from the first wave crest to the air outlet area > the vertical distance M from the second wave crest to the air outlet area.

[0051] The air outlet area 6 extends along the longitudinal direction of the clamping arm, that is, parallel to the longitudinal direction of the hair clamping plate 35. The air outlet area 6 is composed of one or more air outlets and is in an overall long and narrow shape. Since the air flow entering the wind cavity 331 is very fast, a large amount of air flow will directly be ejected from the air inlet end 332 to the wind cavity 331 at the end far from the air inlet end 332 and flow out from some air outlets in the air outlet area 6 at the end far from the air inlet end 332. The above wave crest and trough structure can effectively shunt and guide the air flow, so that the air flow can flow out evenly from the air outlets in the air outlet area 6.

[0052] Based on this structure, by setting the arc-shaped air guiding part 82, the problem of blocked air outlet can be well solved, and even if a heating element is installed in the air cavity 331, the guiding effect on the air flow can still be achieved.

[0053] In the prior art, the heating element usually adopts the method of winding the heating wire 343 with a heat insulation board, but there is no clear requirement on how to set the heating wire 343. During the process of the air flow entering from one end of the air cavity 331 and reaching the other end of the air cavity 331, it will continuously contact the heating element. The longer the residence time in the air cavity 331, the higher the temperature, that is, the temperature of the air flow far from the air inlet end 332 is higher than that of the air flow near the air inlet end 332, which will cause the problem of uneven temperature of the air flow output from the air outlet area 6.

[0054] Assume that a heating element is set at the air inlet end 332. During the process of the air flow entering from one end of the air cavity 331 and reaching the other end of the air cavity 331, the temperature will gradually decrease.

[0055] Assume that a strip-shaped heating element is set in the air cavity 331, and the winding density number of the wound heating wire 343 has no change. During the process of the air flow entering from one end of the air cavity 331 and reaching the other end of the air cavity 331, the temperature will increase.

[0056] The present utility model solves the above problems by adjusting the heating wire 343, specifically including at least one spacer 341. Parallel mica plates 342 are respectively arranged on the upper and lower end faces of the spacer 341, and the heating wire 343 is wound on the mica plates 342. The winding density of the heating wire 343 gradually decreases from the end close to the air inlet end 332 to the other end.

[0057] When the air flow initially enters the air cavity 331, it contacts the part of the heating wire 343 with a higher density. At this time, the air flow temperature is the highest. During the process of the air flow moving towards the other end, the density of the heating wire 343 gradually decreases, and its function is to maintain the current temperature of the air flow, so that the temperature at each position in the air cavity 331 is kept consistent, and finally the temperature of the air flow output from the air outlet area 6 is balanced.

[0058] Further, referring to Figure 7 、 Figure 9 and Figure 10 , at least one arc-shaped air guiding part 82 protruding into the air cavity 331 is arranged at the position of the air guiding part 81 close to the dense area of the heating wire 343. Preferably, the air outlet area 6 is a long strip hole, and a number of connecting ribs 84 are arranged in the air cavity 331. In addition to strengthening the structure, the connecting ribs 84 divide the long strip hole into several areas. Each arc-shaped air guiding part 82 will form a wave crest and a wave trough, which can better guide the air flow towards the air outlet area 6.

[0059] In addition, a clamping plate 83 is provided at a position near the edge of the air inlet end 332. A clamping groove 344 that cooperates with the clamping plate 83 is provided at the end of the mica plate 342 for fixing the first heating element 34. Moreover, the clamping plate 83 also has a guiding effect on the air flow. The clamping plate 83 cooperates with the air guiding member 81, making the air cavity 331 near the air inlet end 332 in an "eight-shaped" configuration, enabling the incoming air flow to closely adhere to the air guiding member 81 and move along the direction of the air guiding member 81.

[0060] In this embodiment, a plurality of heat dissipation ventilation holes 345 are provided on both mica plates 342. The air flow can shuttle through the plurality of heat dissipation ventilation holes 345 and carry away the heat of the heating wire 343.

[0061] Further, referring to Figure 8 , the first heating element 34 further includes a fuse 346. The fuse 346 is fixedly arranged between the two mica plates 342 and at the end far from the air inlet end 332. The fuse 346 is one of the necessary safety components of the heating element. By arranging the fuse 346 in the corner, the resistance generated during the movement of the air flow can be reduced.
