Description

Technical Field

[0001] The present invention relates to the technical field of beauty and hair care tools, and particularly to a hair care comb, such as a straightening comb. Background Art

[0002] Straightening combs are widely used in the hair styling industry and can be used to straighten hair. A straightening comb mainly consists of a housing, comb teeth, a handle, etc. Some also have heating devices, metal comb teeth with good heat conduction (such as heated comb teeth), heat insulation devices, etc. It is beneficial to straighten hair when it passes through the heated metal comb teeth. Traditional straightening combs can only comb hair. Even if heating devices are provided, they can only help heat the hair, and the straightening effect on the hair is not very good. For this reason, someone invented a straightening comb with a blowing function. For example, a blowing air direction changing device and a straightening comb disclosed in Chinese Patent Application CN119523239A can automatically block the left air duct or the right air duct according to the inclination angle of the straightening comb by relying on the gravity of a movable part arranged in the air distribution cavity, so that when the user combs the hair, there is no need to manually adjust the air flow direction, and the air flow path will be automatically optimized according to the actual position and movement of the comb. However, the air flow of this solution can only be blown out along the direction of the comb teeth and cannot make the air flow out along the direction of hair combing. Therefore, its function is only to avoid the extra pulling and pressure on the hair caused by the reverse air flow and reduce the risk of hair breakage or splitting, but it cannot play a role in helping to straighten the hair. Summary of the Invention

[0003] Aiming at the disadvantages of the prior art, the present invention provides a hair care comb with a more reasonable and simpler structure, which can make the air flow out along the direction of hair combing, so as to help straighten the hair and make the straightening effect and user experience better.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: A hair care comb includes a housing, a comb tooth assembly, and an air duct. The comb tooth assembly includes a fixed comb tooth member and a movable comb tooth member. The fixed comb tooth member includes fixed comb teeth and a fixed comb tooth base. The fixed comb tooth base is fixedly installed on the housing, and an air outlet channel is provided in the fixed comb tooth base. The movable comb tooth member includes movable comb teeth and a movable comb tooth base. The movable comb tooth base is movably installed in the air outlet channel of the fixed comb tooth base to form a structure that can swing left and right. The air duct is arranged in the housing, and the movable comb tooth member is docked with the air duct. An air flow channel is formed through the gaps generated on the left and right sides of the movable comb tooth member when it swings, and the air flow channel is communicated with the air duct. On both sides of the movable comb tooth base, guide edges extend outward, and on the fixed comb tooth base, stop edges extend toward the middle from both sides along the air outlet channel. The width of the entire movable comb tooth base is greater than the width of the air outlet channel between the two stop edges, so that when the movable comb tooth member swings toward one side, the guide edge on that side rotates to press against the stop edge on the same side to close the air flow channel on that side and expose the air flow channel on the other side. The surface of the guide edge opposite to the stop edge is set as an arc-shaped concave surface, so that the outer end of the guide edge bends toward the stop edge, and a structure for guiding the air outlet to be consistent with the hair combing direction is formed through the arc-shaped concave surface.

[0005] Further, axle pins are respectively arranged at the front and rear ends of the movable comb tooth base, and the axle pins are embedded in the fixed comb tooth base at both ends of the air outlet channel to form a structure that can rotate left and right.

[0006] Further, at least one ring is arranged on each axle pin, and a rotation groove is arranged at the position corresponding to the ring in the movable comb tooth base, and the ring is snapped into the rotation groove.

[0007] Further, it also includes heating comb teeth and a heat insulation comb tooth member. The heating comb teeth are connected with a heating element. The heat insulation comb tooth member includes heat insulation comb teeth and a heat insulation comb tooth base. The heat insulation comb tooth member is sleeved outside the heating comb teeth, and each heating comb tooth corresponds to one heat insulation comb tooth.

[0008] Further, the heat insulation comb tooth base covers the fixed comb tooth base to clamp the axle pins of the movable comb tooth base, so that the axle pins can rotate between the fixed comb tooth base and the heat insulation comb tooth base.

[0009] Further, the movable comb tooth member is arranged in the middle area of the fixed comb tooth member, and the heating comb teeth are arranged on one side or both sides beside the movable comb tooth member.

[0010] More preferably, at least two rows of heating comb teeth are arranged on both sides of the movable comb tooth member, and the adjacent rows of heating comb teeth are arranged in a staggered manner.

[0011] Preferably, the bottom of the air duct is a structure that gradually rises forward, so that the distance between the movable comb tooth base and the bottom of the air duct gradually becomes smaller forward.

[0012] Furthermore, the housing includes a front shell and a bottom cover, and the two are combined and docked to fix and assemble the fixed comb teeth member, the heat insulation comb teeth member and the air duct; a connector is installed at the tail ends of the front shell and the bottom cover, and conductive pins are arranged in the connector; a transfer board is arranged between the front end of the connector and the tail ends of the front shell and the bottom cover, and the electrical connection between the heating element and the conductive pins is realized through the transfer board; a connection groove is arranged on the surface of the connector, and a detachable connection structure is formed with the host with a blower through the connection groove.

[0013] In the present invention, stop edges are respectively arranged on both sides of the air outlet channel of the fixed comb tooth seat, and diversion edges respectively protrude outwards on both sides of the movable comb tooth plate, and the diversion edges protruding towards both sides can cover the stop edges. When the movable comb tooth member swings left and right with the action of combing hair, the diversion edge on one side will press against the corresponding stop edge to close the air flow channel on that side, and at the same time open the air flow channel on the other side, and the air flow blows outwards through the air flow channel along the extension direction of the diversion edge, so that the blowing direction is basically the same as the hair combing direction, so as to achieve the effect of combing the hair straighter while drying the hair, realizing a better hair straightening effect and improving the user experience.

Specific Embodiment

[0023] In this embodiment, referring to Figures 1 - 8 , the hair care comb can be used in cooperation with the main body 8 with a blower, and includes a housing composed of a front shell 11 and a rear cover 12, a comb tooth assembly, and an air duct 6. The comb tooth assembly includes a fixed comb tooth part 2 and a movable comb tooth part 3. The fixed comb tooth part 2 includes a fixed comb tooth 21 and a fixed comb tooth seat 22. The fixed comb tooth seat 22 is fixedly installed on the front shell 11, and an air outlet channel 23 is provided in the fixed comb tooth seat 22. The movable comb tooth part 3 includes a movable comb tooth 31 and a movable comb tooth seat 32. The movable comb tooth seat 32 is movably installed in the air outlet channel 23 of the fixed comb tooth seat 22 to form a structure that can swing left and right, and the swinging angle is 3 - 45 degrees. The air duct 6 is installed in the bottom cover 12 and is pressed by the front shell 11 (the air duct 6 can also be set to be an integral structure with the bottom cover 12). The movable comb tooth part 3 is docked with the air duct 6, and an air flow channel 9 is formed through the gaps generated on the left and right sides when the movable comb tooth part 3 swings. The air flow channel 9 is communicated with the air duct 6. The two sides of the movable comb tooth seat 32 extend outwards to form guide edges 35, and the fixed comb tooth seat 22 extends towards the middle from both sides along the air outlet channel 23 to form stop edges 24. The width of the entire movable comb tooth seat 32 is greater than the width of the air outlet channel 23 between the two stop edges 24, so that when the movable comb tooth part 3 swings towards one side, the guide edge 35 on that side rotates to press against the stop edge 24 on the same side to close the air flow channel 9 on that side and expose the air flow channel 9 on the other side. The surface of the guide edge 35 opposite to the stop edge 24 is set as an arc-shaped concave surface 36, so that the end of the guide edge 35 is slightly tilted towards the stop edge 24. In this way, the air outlet will be guided to be consistent with the hair combing direction through the arc-shaped concave surface 36, which can significantly help to straighten the hair 10 and at the same time make the hair blow softer. For example, when combing the hair 10 to the right, the movable comb tooth 31 rotates to the left due to the force to the left. At this time, the air flow channel 9 on the left side will be closed, and the air flow channel 9 on the right side will be completely opened, so that the wind blows out to the right along the arc-shaped concave surface 36 of the guide edge 35 on the right side along the direction of combing the hair, as Figure 5 shown. When combing the hair 10 to the left, the blowing direction of the wind will be changed to blow out to the left along the direction of combing the hair, as Figure 6as shown

[0024] Shaft pins 33 are respectively arranged at the front and rear ends of the movable comb tooth seat 32. The shaft pins 33 are embedded in the fixed comb tooth seats 22 at both ends of the air outlet channel 23 to form a structure that can rotate left and right, that is, rotate around the shaft pins 33.

[0025] A retaining ring 34 is arranged on each shaft pin 33. A rotating groove 25 is arranged at the position corresponding to the retaining ring 34 in the movable comb tooth seat 32. The retaining ring 34 is snapped into the rotating groove 25, which can play a role in preventing detachment.

[0026] It further includes a heating comb tooth 4 and a heat insulation comb tooth member 5. The heating comb tooth 4 is connected with a heating element 41 (PTC and / or NTC heating element). The heat insulation comb tooth member 5 includes a heat insulation comb tooth 51 and a heat insulation comb tooth seat 52, which can be made of silica gel. The heat insulation comb tooth member 5 is sleeved outside the heating comb tooth 4, and each heat insulation comb tooth 51 corresponds to one heating comb tooth 4. The hair is heated by the heating comb tooth 4 to soften the hair, and further comb the hair straighter and smoother.

[0027] The heat insulation comb tooth seat 52 covers the fixed comb tooth seat 22 to clamp the shaft pin 33 of the movable comb tooth seat 32, so that the shaft pin 33 can rotate between the fixed comb tooth seat 22 and the heat insulation comb tooth seat 52.

[0028] The movable comb tooth member 3 is arranged in the middle area of the fixed comb tooth member 2, and the heating comb tooth 4 is arranged on both sides (only one side is also okay) beside the movable comb tooth member 3. Two rows of heating comb teeth 4 are arranged on both sides of the movable comb tooth member 3 respectively, and the adjacent rows of heating comb teeth 4 are arranged in a staggered manner, so that a greater frictional force can be provided to the hair, and the straightening effect is further improved.

[0029] The bottom of the air duct 6 is a structure that gradually rises forward, so that the distance between the movable comb tooth seat 32 and the bottom of the air duct 6 gradually becomes smaller forward, which can form a squeezing effect on the air and improve the pressure of the blown air.

[0030] The front shell 11 and the bottom cover 12 are combined and docked to assemble and fix the fixed comb tooth member 2, the heat insulation comb tooth member 5 and the air duct 6; a connector 7 is installed at the tail end of the front shell 11 and the bottom cover 12, and a conductive pin 72 is arranged in the connector 7; a wiring board 73 is arranged between the front end of the connector 7 and the tail end of the front shell 11 and the bottom cover 12, and the electrical connection between the heating element 41 and the conductive pin 72 is realized through the wiring board 73; a connection groove 71 is arranged on the surface of the connector 7, and an anti-detachment groove is also arranged. On the main body 8, a connection buckle and an anti-detachment buckle that are respectively matched with the connection groove 71 and the anti-detachment groove can be arranged, and the connection buckle and the connection groove 71, the anti-detachment buckle and the anti-detachment groove are inserted into each other to form a detachable connection structure with the main body 8, so that the main body with different functions can be flexibly replaced. For example, a heating body 81 can also be arranged in the main body 8 to blow out hot air.

[0031] The present invention has been described in detail above. As described above, the above is only the preferred embodiment of the present invention, and it is not possible to limit the scope of the present invention. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
