Description

Technical Field

[0001] The utility model belongs to the technical field of hair care tools, and particularly relates to a diversion and heat conduction structure for a hair care tool. Background Art

[0002] Hair care tools generally refer to straighteners, hair dryers, curling irons, etc. Among these tools, there is basically a blowing function. Taking a straightener as an example, as disclosed in the technical literature "CN 117958540 A, a blowing straightener", an air delivery cavity is provided inside two clamping plates, a strip-shaped installation groove extending along the length direction of the hair clamping plate 2, and a first strip-shaped air outlet communicating with the air delivery cavity in the same direction as the strip-shaped installation groove. By driving the fan blade to rotate by a motor and heating by a heating element, hot air is blown out from the first strip-shaped air outlet. When the hair is clamped by the clamping strips through the opposite movement of the hair clamping plates, the hair can be heated.

[0003] During the process of blowing out the air flow, it must pass through the air delivery cavity. Since the heating element occupies the space of the air cavity, a partitioned air guide plate cannot be arranged in the air cavity to guide the air flow to be ejected more evenly from the air outlet area. Most of the air flow will be ejected from some air outlets in the air outlet area far from the air inlet end when entering the air cavity from the air inlet end, resulting in less air volume at some air outlets in the air outlet area near the air inlet end. Content of the Utility Model

[0004] The purpose of the utility model is to provide a diversion and heat conduction structure for a hair care tool to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A diversion and heat conduction structure for a hair care tool, including a box body. An air guide member extending obliquely is provided in the box body. The air guide member, the box body and the cover plate enclose to form an air cavity. An air outlet area is provided on one side of the box body far from the air guide member. An air inlet end communicating with the air cavity is provided at one end of the box body. The width of one end of the air cavity close to the air inlet end is C, and the width of the end far from the air inlet end is D, and width C > width D;

[0007] A heating element one is provided in the air cavity, and the air guide member is provided with at least one arc-shaped air guide portion protruding into the air cavity.

[0008] In a further technical solution, one arc-shaped air guide portion corresponds to one wave crest and one wave trough.

[0009] In a further technical solution, a clamping plate is provided at the edge position close to the air inlet end, and a clamping groove cooperating with the clamping plate is provided at the end of the mica plate.

[0010] Further technical solution: The first heating element includes at least one spacer. Mica plates are respectively provided on the upper and lower end faces of the spacer and are arranged in parallel. Heating wires are wound on the mica plates, and the winding density of the heating wires gradually decreases from one end close to the air inlet end to the other end. A number of heat dissipation ventilation holes are provided on both mica plates.

[0011] Further technical solution: The first heating element further includes a fuse, and the fuse is fixedly arranged between the two mica plates and at the end far from the air inlet end.

[0012] Further technical solution: A hair clamping plate is provided on one side of the box body far from the air outlet area, and the hair clamping plate is connected to the second heating element.

[0013] Further technical solution: The upper surface of the hair clamping plate is higher than the upper surface of the cover plate. There is a gap between the hair clamping plate and the cover plate. The width of the surface of the cover plate is B, and the width of the hair clamping plate plus the gap is A, and width B > width A.

[0014] Further technical solution: A slope is provided on one side of the cover plate close to the hair clamping plate, and the bottom of the hair clamping plate is hollowed out to form a guiding channel with the slope.

[0015] Further technical solution: A hair clamping strip is provided at a position on the surface of the cover plate close to the air outlet area. There is an isolation area between the hair clamping strip and the edge of the air outlet area.

[0016] Further technical solution: There are at least two wave peaks. There is a wave trough between two adjacent wave peaks. The vertical distance L from the first wave peak to the air outlet area > the vertical distance M from the second wave peak to the air outlet area.

[0017] Advantages of the present utility model:

[0018] In the present utility model, a wind guiding member is arranged on the opposite side of the air outlet area. When the air flow enters the air cavity from the air inlet end and encounters the first wave peak, the air flow is divided into two strands. One strand inclines towards the air outlet area and flows out to the outside, and the other strand continues to move forward along the surface of the wave trough of the wind guiding member for a certain distance and then inclines towards the air outlet area and flows out to the outside or reaches the second wave peak and is divided again. This technical feature of air flow diversion and guiding does not occupy the space of the air cavity, and the air flow is smooth with low noise, so that the air flow can flow out evenly from the air outlet of the air outlet area;

[0019] In addition, when the air flow initially enters the air cavity, it comes into partial contact with the relatively dense part of the heating wire. At this time, the temperature of the air flow is the highest. During the process of the air flow moving towards the other end, the density of the heating wire gradually decreases. Its function is to maintain the current temperature of the air flow and make the temperature at each position in the air cavity consistent. Finally, the temperature of the air flow output from the air outlet area is balanced.

[0020] Other features and advantages of the present utility model will be described in detail in the following specific implementation section. Description of the Drawings

Specific Embodiments

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

[0034] Please refer to Figure 1-11 ;

[0035] The hair straightener 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 hair straightener is moved along the straightening direction of the hair to complete the straightening operation. In the present invention, 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, then close the clamping arms 1 and 2 so that the straightening components 1 and 2 clamp the hair. The straightening components 1 and 2 cooperate to heat the hair. At the same time, the air flow generating component 5 is activated 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 increase. 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 areas of the clamping arms 1 and 2. When in use, the hair is located between the two air outlet areas 6, so the two ejected air flows 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, the hair can be contacted at the edge areas of the clamping arms 1 and 2, deliberately reducing the time for the air flow to stay outside, which also plays a role in reducing energy loss. Moreover, the output air flow is not blocked by other components and has a relatively fast flow rate, 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 first clamping arm 1.

[0039] In the present utility model, the structures of the first straightening component 3 and the second straightening component 4 are the same, that is, 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. In order to avoid excessive temperature aggregation on one side, a first heat dissipation area 71 is provided on both 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 first straightening component 3 will be taken as an example for description below;

[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 provided on one side of the box body 31 and communicates with the air cavity 331. A first heating element 34 is provided in the air cavity 331. An air flow generating component 5 inputs air flow into the air cavity 331. These air flows will stay in the air cavity 331 for a short time and will be heated by the first heating element 34, thereby increasing the temperature of the air flow. A hair clamping plate 35 is provided on the side of the box body 31 away from the air outlet area 6. A floating member 36 is provided 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 hair is clamped by the two hair clamping plates 35 on the first straightening component 3 and the second straightening component 4. 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 air flow, which can quickly increase the temperature of the air flow. 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 6, in the initial state, the upper surface of the hair clamping plate 35 is higher than the upper surface of the cover plate 32. Since a floating member 36 is provided between the hair clamping plate 35 and the box body 31, the two hair clamping 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 element 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 element 34, while the hair clamping plate 35 occupies relatively little space. The hair clamping plate 35 and the cover plate 32 are arranged at intervals to avoid clamping 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 clamping plate 35. The width of the surface of the cover plate 32 is B, and the width of the hair clamping 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 element 34.

[0044] In addition, when the hair has moisture, the two hair clamping 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 clamping plate 35 is provided with an inclined surface. The bottom of the hair clamping 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 the second heating element 37 can be dissipated.

[0045] Based on the above structure, only the two hair clamping 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, and the hair is likely to fly randomly when the two airflows are output. 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. The hair clamping strip 391 and the hair clamping plate 35 are used in cooperation to form a way to fix both ends of the hair;

[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 clamping plate 35 is higher than the hair clamping strip 391. When it is necessary to clamp and fix the hair, first, the two hair clamping plates 35 contact the hair. When clamping forcefully, the hair clamping 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 clamping plates 35, that is, the floating amplitude.

[0047] Furthermore, referring to Figure 6 , the position at the edge of the air outlet area 6 will be 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 either. Instead, 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. Below, 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 the wind cavity 331 at one end close to the air inlet end 332 is C, and the width at 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 parts. One part inclines towards the air outlet area 6 and flows out to the outside, and the other part 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 diversion technical feature does not occupy the space of the wind cavity 331 and the air flow is smooth and the noise is low. 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 overall in a 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 divert 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 providing 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 arrange 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, 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 provided 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, the temperature will gradually decrease.

[0055] Assume that a strip-shaped heating element is provided in the air cavity 331, and the winding density 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, 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 provided 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 near 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 provided 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 plurality of connecting ribs 84 are provided in the air cavity 331. In addition to strengthening the structure, the connecting ribs 84 also divide the long strip hole into several regions. 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 close to 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 cooperation between the clamping plate 83 and the air guiding member 81 makes the air cavity 331 near the air inlet end 332 in a "V-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 can carry away the heat of the heating wire 343.

[0061] Furthermore, 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 away 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.

[0062] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0063] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
