Description

Rubber component, hair comb and manufacturing method of hair comb

Technical field

The invention belongs to the technical field of daily necessities, and specifically relates to a rubber component that can be used for a hair comb, a hair comb containing the rubber component, and a method for manufacturing the hair comb.

Background technique

Hair comb (also known as comb) is a tool for combing hair, with various types and materials. Hair comb is a common item in people's daily life. It is a very necessary and practical tool for hair care, especially long hair. On the basis of traditional hair combs, many hair combs with subdivision functions and application scenarios have been further evolved. Air cushion combs are one of them.

Air cushion comb (also known as air bag comb) is to place the comb needle of the hair comb on a rubber or other similar flexible material, and a cavity is formed between the rubber and the main body of the comb. When the comb needle acts on the hair or scalp when used , Produce a force on the cavity, because the rubber is soft, the air in the cavity is discharged from the special pores. Thereby, it can fit the shape of the scalp better, and at the same time, the flexible contact effect can also realize the massage of the scalp.

KR101317714B1 discloses a comb provided with detachable comb teeth to reduce manufacturing costs and accommodating space. The comb includes a main body part 110 that forms a handle 111 and has a main body 112 into which the comb body is inserted. Combining detachably together with the main body are formed with comb teeth, and an opening and closing portion 130 formed on the end of the main body. Guide grooves 113 formed on both ends of the main body are connected to guide protrusions 122 formed on both ends of the comb-tooth main body. The hair comb can select a hair style produced by the comb body according to the user's hair condition, thinning hair and hair length, choose a comb body suitable for the hair style, and use the comb body detachably to reduce the purchase cost. Storage space; when foreign matter is contaminated by the comb-shaped body formed by the comb during long-term use, it is easy to separate and clean by allowing the comb to be attached/detached and has a good hygienic effect.

KR20160080197A discloses a comb tooth for a hair brush, which comprises: a scalp anti-scratch member formed on the top of the upright comb frame, an upper frame and a lower frame are formed on the bottom of the upright comb frame, and a plurality of rings are formed on the On the middle part of the upright comb frame. The bottom of the comb tooth is provided with a lower locking pawl 130, a lower locking pawl 140, and a locking rod 150 located between the two. The rubber plate 200 is provided with a comb tooth hole 210, so that the lower end of the comb can be fixed by the combined rubber plate 200 to form a lower The locking pawl 140 and the upper locking pawl 130 are formed into a conical shape; so that the comb teeth are fixed on the rubber plate 200. The comb teeth can not only maintain the wavy hair by forming multiple rings in the middle part of the vertical comb frame, so that the wavy hair is easier to comb, but also can comb the hair, which can fundamentally prevent the hair from being combed. Tangle or twist in the middle to maintain a neater state.

KR20110085799A also discloses a hair comb, which provides a hair comb that can prevent dust from being adsorbed on the comb plate, comb teeth, and easily remove tangled hair. The comb includes a main body 1, and a first comb plate 11 is adhered to the main body. The second comb plate 12 is adhered to the first comb plate, the bottom plate 3 is adhered to the first and second comb plates, and the inserted comb teeth 6 are used to move up and down between the first comb plate and the second comb plate. Moving, the first comb plate includes a top plane and a side plane surrounding the top plane, a plurality of holes are formed in the upper plane, and the side surface is formed in a zigzag shape. The bottom of the comb teeth 6 is also fixed to the second comb plate 12 through the recesses 5c in the holes 2, which is similar to KR20160080197A.

KR20160047289A discloses a brush with three comb teeth. By forming the comb teeth to have three lengths, when combing tangled hair, it can prevent hair from being pulled or cut; and when combing hair, it can prevent Hair cutting caused by inserting hair between the comb teeth and the comb tooth pad. The brush 10 is formed by connecting a comb tooth pad 40, in which a plurality of comb teeth 30 are inserted and fixed in a predetermined arrangement, wherein one surface 20 of the main body part connects the handle 50 with another part of the main body part 20, The comb teeth 30 have a triple structure including long comb teeth 31 and middle comb teeth 32. The short comb teeth 33 have different lengths, and the protrusion 41 for preventing hair insertion is on the upper surface of the comb tooth pad 40. Prominent between 30. The comb tooth pad 40 can be formed by the rubber of an air-cushioned comb. The bottom of the comb tooth 30 is provided with two convex rings 30a and 30b. The comb tooth 30 is engaged in the comb tooth hole of the comb tooth pad 40 via the two convex rings 30a and 30b to achieve Fixation of comb teeth 30.

CN2347471Y discloses a combined comb, which comprises a head and a handle, the head has a tail handle and the handle is hollow, and the two are inserted and fixedly connected to each other as a whole. Although it mainly discloses that combs of different varieties or serial production can be assembled through different combinations, it can be seen from Figure 1 that the comb needles are fixed to the comb through a way that the outer diameter of the bottom is larger than the inner diameter of the comb hole On the rubber.

It can be seen that the use of soft rubber as the installation carrier for comb needles (also called comb teeth) is one of the necessary structures for air-cushion combs, and the comb needles are mostly injection molded from plastics and other materials, and the bottom of the comb can be set on the rubber. The upper and lower locking claws of the upper comb tooth hole are also a common fixing structure for comb needles. Although such a structure can achieve a massage effect on the scalp, and KR20160080197A also discloses that a number of rings 160 are provided on the comb teeth to use the combing of wavy hair, it does not fundamentally solve the problem of using plastic comb needles for this type of hair comb 2 And cause the hair knot problem. Fundamentally, the root cause of this problem is that the material of the comb needle is relatively hard. When it encounters curls and knots, it will push the knotted part to move downwards, and eventually make the comb needle tightly tied to the hair. The ground is stuck, which will affect the performance of combing.

To solve this problem, it is necessary to deal with the root cause of the hard needle; in general technology, most of the problems are alleviated by adding additional structures like KR20160080197A; the root cause of this problem is not realized. What is it and how to solve this problem. To solve this problem, we tried to replace the comb needle with a softer material, but this will bring another new problem-how to firmly fix the comb needle to the rubber. Obviously, for the traditional plastic comb teeth, due to their hard material and relatively large diameter, they can be fixed in the comb teeth holes of the rubber by the upper and lower locking claws mentioned above, and be firmly fixed. However, if a softer material of the comb needle is replaced, if the same structure is adopted, the fixing strength is obviously insufficient. On the one hand, such materials and specifications are not suitable for injection molding. On the other hand, even if It is manufactured. When it encounters hair knotting, the comb teeth will be peeled from the rubber because the fixing force between the bottom of the comb needle and the rubber is not strong. This is also the biggest problem we encountered when developing the hair comb of the present invention.

The traditional method may choose to glue the method, that is, apply glue to the bottom of the comb needle and place it in the comb tooth hole. In order to ensure sufficient adhesion, a sufficient contact area is required. Therefore, it will increase the thickness of the rubber. The method makes the two have sufficient contact area to facilitate the fitting and fixing. However, the increase in the thickness of the rubber skin will obviously make the overall use effect of the air cushion comb worse, and the external force required for the deformation of the rubber skin will increase, which will greatly affect the massage effect and the user's satisfaction with the use of the air cushion comb.

Summary of the invention

The purpose of the present invention is to solve the above-mentioned problems and provide a new type of fixed structure for air-cushion comb needles, so as to solve the problem of knotting in existing air-cushion combs, and at the same time ensure the firm combination of the comb needles and rubber.

As the first aspect of the present invention, a rubber component is provided, which includes a comb needle and rubber, and a number of raised posts are arranged on the back of the rubber, and the bottom of the comb needle is bent and fitted into the raised posts through a clamping piece , So that the fixing effect with the rubber skin meets the requirements, and the main body thickness of the rubber skin has not increased, so that the overall use effect of the air cushion comb is not affected; and the raised column can make the related fixing structure of the comb needle and the rubber skin (that is, the comb needle bent The folding and clamping pieces have sufficient space for installation, that is to say, the fixing method of the protruding column with the bending and clamping pieces can ensure that the fixing strength meets the requirements without affecting the thickness of the rubber.

As a second aspect of the present invention, there is provided a hair comb containing the rubber component, which mainly applies the above rubber component to the hair comb to realize the realization of a knotless hair comb. In addition, the rubber component and the comb handle are connected by a clamping structure, which is detachable, which is very beneficial in the maintenance of the hair comb; when there are curly hair wrapped around the root of the rubber comb needle, the traditional head The comb can only be cleaned manually, which is very inconvenient, or the use of additional cleaning components as described in KR20110085799A, but this will significantly increase its structural complexity. In this comb, since the rubber component is detachable, it can be disassembled to form a flat part, and then placed in the water with the comb needle down, and the rubber component can be lifted to make the curls fall off automatically , This can easily clean most of the hair.

As a third aspect of the present invention, a method for making a hair comb is provided. The hair comb made according to this method has an ingenious structure and low overall manufacturing cost, which solves the problem of hair knotting and is easy to clean; at the same time, It also completely retains all the functions of the traditional air cushion comb without any reduction. With the special comb handle structure, the comb surface of the comb is flat and the contact surface with the hair or scalp is larger when combing. This is a traditional air cushion. What the comb does not have. In addition, it also solves the problems of fixing strength and safety caused by fixing the traditional non-knotted hair comb with glue, as well as the weakening of massage effect caused by the increase of rubber thickness.

The present invention solves the problem of knotting hair in traditional air-cushion combs by selecting comb needles of softer material; at the same time, the fixing structure of comb needles is redesigned so that it does not increase the thickness of the rubber skin and affects the entire air-cushion comb. The massage effect has an adverse effect, and it can also ensure that the fixing of the comb needle and the rubber is firm and effective, and avoid the use problems caused by insufficient fixing strength of the comb needle. At the same time, after the rubber component is fitted to the comb handle, on the one hand, the rubber component can be detachable and easy to clean. On the other hand, the comb surface body can be made straight through the design of the comb handle structure, so that it can interact with the user’s hair or The head has a larger contact area.

detailed description

In order to enable those skilled in the art to better understand the present invention and thus to more clearly define the scope of protection of the present invention, the present invention will be described in detail below with respect to some specific embodiments of the present invention.

As shown in Figs. 1-8, a rubber skin component includes a comb needle 1 and a rubber skin 2. The comb needle 1 is directly or indirectly fitted on the rubber skin 2 to form the rubber skin component. The back of the rubber 2 is also provided with a plurality of raised posts 3, which are arranged independently and spaced apart. As shown in Figs. 1 and 2, each raised post 3 has a certain clearance space between each other, so that the rubber The overall thickness of the component during use does not increase due to the arrangement of the raised pillars 3; in fact, too dense raised pillars 3 will cause such problems to a certain extent, so the thickness and convexity of the rubber 2 can be adjusted according to the actual situation. The parameters and distribution density of the starting column 3 are set accordingly. The protruding column 3 is provided with a pinhole 4 for setting the comb needle 1 and a cavity 31 for accommodating the comb 1. The pinhole 4 penetrates the front surface of the rubber 2, and the cavity 31 is sealed except for the pinhole 4; , A cavity with an opening at one end (that is, a pinhole 4) is formed in the protruding column 3. Therefore, the comb needle 1 passes through the needle hole 4 from the front of the rubber 2 and is placed in the cavity 31, so that the comb needle 1 is fixed on the rubber 2.

The comb needle 1 is made of software material, one end is provided with a hook 5, and the inside of the needle hole 4 is provided with a clamping piece 6 that can be fitted and fixed in the cavity 31; for example, the length of the cavity 31 It is larger than the diameter of the needle hole 4, so that the hook 5 fits tightly in the cavity 31 and hooks the clamping piece 6. Of course, the clamping piece 6 is not limited to a cylindrical shape, a cubic shape or other shapes, and all can be independent The relevant shapes fitted in each cavity 31 are optional. The diameter of the pinhole 4 is equal to or smaller than the inner diameter of the cavity 31. Since the rubber 2 is made of flexible material, it has a certain degree of elasticity. Therefore, the diameter of the pinhole 4 of the above two specifications can allow the clamping piece 6 to be arranged in the cavity. In the body 31. Preferably, the inner diameter of the cavity 31 is matched with the outer diameter of the comb needle 1, so that after the comb needle 1 is bent and fitted into the cavity 31, the inner wall of the cavity 31 can exert a force on it to Makes its fixing effect good. In theory, a smaller inner diameter of the cavity 31 can make the fixing effect of the comb needle 1 better, but it will increase the difficulty of fitting the hook 5 of the comb needle 1 into the cavity 31, while a larger cavity 31 can reduce It is difficult for the hook 5 of the comb needle 1 to fit in the cavity 31, but it will weaken the fixing effect of the comb needle 1 in the cavity 31; therefore, the relative specifications of the two need to be set appropriately. In addition, the hook 5 can be inserted into the cavity 31 together with the clamping piece 6 after hooking it. This way of assembling the comb needle 1 and the rubber 2 is very easy to implement.

Regarding the material of the comb needle 1, in the prior art, plastic is mainly used for injection molding, which is harder and prone to the problem of hair knotting; some patented technologies use spherical or quasi-spherical shapes on the comb needle. The structure is used to alleviate this problem, but it has not been fundamentally solved; therefore, we use a softer material (compared to the traditional plastic material) to make comb needles, which can fundamentally solve this problem. There are many options for the actual material of the comb needle to meet the above-mentioned flexibility requirements; the better one is to use nylon material to make the comb needle 1, more precisely to use nylon wire; nylon wire One end of the finished comb needle 1 is bent to form a hook 5, and the other end is formed as a comb needle head. Compared with the traditional connection method that is clipped to the rubber after injection, the nylon needle is softer, which can fundamentally overcome the problem of hair knotting caused by traditional plastic injection molding needles.

However, the prior art lacks an effective solution to the technical problem of how to fix the nylon comb needle on the rubber more stably and safely. A possible general solution is to fix it with glue; on the one hand, the fixing strength is not high. On the other hand, the volatilization of glue will cause safety problems, and the fixing performance will decrease significantly as the use time is extended. In addition, in order to ensure a sufficient adhesive contact area, the thickness of the rubber skin often needs to be increased accordingly, which will greatly affect the massage effect of the air cushion comb, which is not desirable. Therefore, the present invention adopts a separate design scheme. First, the rubber 2 is designed to support the overall function together, and then a convex post 3 for fixing the comb needle 1 is provided on the back of the rubber 2, and the clamping piece 6 is used to secure the comb needle 1 The ground is fixed in the raised column 3; thus, the fixing strength of the comb needle is enhanced on the basis of avoiding the use of glue. At the same time, the thickness of the rubber 1 does not need to be thickened, that is, the convex column 3 is used to thin the rubber 2. This problem is solved by replacing thick rubber.

Preferably, the thickness of the main part of the rubber 2 in the cross-sectional direction gradually increases from the middle to the edge, that is, the thickness of the middle part is smaller than the thickness of the outer edge part of the rubber 2; this way, on the one hand, the middle part of the rubber 2 can be first contacted and deformed. Some parts are the softest to improve the user experience. On the other hand, the elastic force gradually increases to facilitate the recovery of the rubber 2 after deformation. Practice has shown that the uniform thickness of the rubber, in use, there is a small probability that it will not be able to automatically recover. The above-mentioned design of gradually thickening from the middle to the edge can completely avoid this problem. Generally speaking, the thickness H1 of the center of the main part of the rubber 1 (except the outer edge for rubber fixing) is 1-3mm, and the thickness H2 of the outer edge is 2-5mm. It gradually thickens from the center to the outer edge, but The center to the edge does not require uniform thickening; of course, in theory, stepped thickening is also a feasible solution (for example, the overall thickness is divided into three parts of 1.5mm, 2mm and 3mm from the inside to the outside) . In an embodiment, the thickness H2 of the outer edge of the rubber 1 is 3mm, and the thickness H1 of the thinnest part of the center is 1.5mm (although the thickness change is not obvious in the relevant drawings, the rubber 1 of the present invention is The cross section shown in Figure 3-9 has a gradual thickness from the center to the edge).

Preferably, the protruding column 3 and the rubber 2 are integrally formed by injection molding. Specifically, the manufacturing process of the present invention is also different from the conventional rubber manufacturing process. The conventional rubber manufacturing process is formed by stamping a rubber sheet through a mold, and the comb needle is connected to the rubber by glue, while the structure of the present invention is injection molded. The rubber 2 is injection-molded by the mold, and the comb needle is implanted into the comb needle hole by the machine. Since the length of the clamping piece 6 is greater than the diameter of the pinhole, the clamping piece 6 is closely connected, thus ensuring the comb needle 1 The connection strength between the pinhole 4 and the connection strength is 1.2-1.5kg, while the traditional glue connection comb needle has a tension value of 1.0-1.2kg. Therefore, the connection strength of the present invention is increased without glue , So it is very environmentally friendly, and it can also ensure that the thickness of the rubber 2 does not increase and affect the overall massage effect.

As shown in Figs. 9-13, a hair comb includes a comb handle 7 and a comb part fitted on it, and the comb part is the aforementioned rubber component.

Preferably, the comb handle 7 includes a placing groove 8 for placing the rubber skin 2, the edge of the placing groove 8 is provided with a transverse clamping groove 9, and the outer edge of the rubber 1 is provided with a clamping block 10 The rubber 1 is installed in the placement groove 8, and the clamping block 10 is snap-fitted with the clamping groove 9 so that the center of the rubber bulges toward the front. The thickness of the clamping block 10 is greater than the middle part of the rubber 2.

Preferably, the shape of the clamping groove 9 and the clamping block 10 is a tooth shape or a triangle shape. More preferably, the groove surface of the clamping groove facing the back of the comb handle is provided with a second inclined surface 12 inclined to the front and the center of the rubber 2, and the clamping block 10 is in contact with the second inclined surface 12; the clamping block The back surface of 10 is provided with a first inclined surface 11 that is inclined outward and toward the front direction of the rubber 2, and the first inclined surface 11 is in contact with the second inclined surface 12. The clamping block 10 includes a ring-shaped notch 13, and the step groove and the comb handle 7 are clamped together.

The traditional air-cushion comb forms an air-cushion or airbag structure due to the expansion of the rubber, which will make the middle of the rubber bulge relative to the edge, forming an ellipsoidal-like rubber and comb surface (that is, the curved surface where the top of the comb needle is located).

For this reason, the placement groove 8 of the comb handle 7 of the hair comb of the present invention is arranged to be curved toward the back side of the rubber 2, and after the rubber component is fitted to the comb handle 7, the rubber 2 is straight in the AA direction; The comb needle 1 is also straight in this direction (as shown in Figures 10 and 13), so that the contact surface between the comb needle surface and the hair or scalp can be enlarged. At the same time, as shown in FIGS. 10-13, the edges on both sides of the placement groove 8 are relatively downwardly recessed to form low points 82 on both sides, and the two ends in the straight direction are respectively formed as flat ends 81. In other words, the placement groove 8 of the traditional hair comb is basically an elliptical shape located on the same plane. The placement groove 8 of the comb handle 7 of the present invention is equivalent to keeping its long axis direction unchanged and changing its short axis direction. Bent down respectively to form the placement groove 8 as shown in Figs. 10-13. The placement groove 8 uses the solution that the upper edge of the rubber 1 is tilted downward in the minor axis direction to achieve the effect of not staying under the rubber in a flat state, and at the same time, it can also provide good restoring force under the rubber on time. Of course, the above solution with the long axis unchanged and the short axis tilted down is not fixed, and the direction reversal or proper rotation are also possible alternative implementations.

In other words, due to the structure of the placement groove 8 and the rubber 1, the surface of the traditional rubber 1 is basically spherical or ellipsoidal, while the edges on both sides of the placement groove 8 of the present invention are relatively downwardly recessed, so that the rubber 1 After being fitted into it, it is set along a curved surface shape similar to the shape of a curved TV, that is, the rubber is divided into two parts on the left and the right through the line between the two flat ends 81 (called a flat line), and the left and right parts are downward respectively. It is formed by lifting; more specifically, the curved shape is a trajectory formed by a straight line as a moving line continuously moving in a parabolic direction in space. Figures 9 and 10 show a better embodiment. It can also be seen from the figure that the rubber 1 of the hair comb is in a straight line in the direction of the curved surface, which is different from the traditional spherical or elliptical surface. The spherical comb is completely different; this structure can increase the contact area of the comb with the scalp or hair, and the overall fit when combing the hair is also better; at the same time, the curved structure is matched with the design of the thinner middle and thicker periphery of the peeling 1. In addition, since it is flat along the centerline direction, the rubber 1 will be stretched in the centerline direction after the middle part is deformed, thereby providing a restoring force in the other direction. That is to say, the rubber of the present invention not only has the recovery force generated by the compression of the downturned parts on both sides, but also has the recovery force generated by the stretching of the straight central part. In addition, although the above description and Figures 9 and 10 mainly describe the downward warping in a certain direction (or set along a certain curved surface), although the curling direction of the rubber 1 is not limited to this direction, any similar The curling scheme (not including the traditional spherical curling) is feasible in principle.

As shown in Figures 9 and 14, in the general technology, the rubber is deformed and raised after being installed on the comb handle 7. When combing the hair, a lateral pressure F will be generated, so the contact area between the edge of the rubber and the clamping groove 9 is very large. Small, so the rubber is not firmly installed and easy to fall off. In order to solve this problem, as shown in FIG. 9, the groove surface of the clamping groove facing the back of the comb handle is provided with a second inclined surface 12 inclined to the front and the center of the rubber 2. The clamping block 10 and the second inclined surface 12 In contact, the inclination angle of the second inclined surface 12 can be used to block the lateral pressure F generated by the comb head as much as possible, thereby increasing the connection strength between the clamping block and the clamping block, so that the rubber is not easy to fall off. The back side of the clamping block 10 is provided with a first inclined surface 11 that is inclined outwards and toward the front of the rubber 2. The first inclined surface 11 is in contact with the second inclined surface 12. As the rubber 2 is deformed as a whole, the first inclined surface 11 The angle of the inclined surface 11 is changed and is close to the inclination angle of the second inclined surface 12, thus increasing the contact area between the first inclined surface 11 and the second inclined surface 12, thus further improving the connection strength between the clamping block and the clamping block . The clamping block 10 includes a ring-shaped notch 13, and the stepped groove is clamped with the comb handle 7, and the appearance is more flat.

A method for making a hair comb includes the following steps:

The hair comb is configured to include a comb handle and a rubber component, which are detachably matched; the rubber component further includes a comb needle 1 and a rubber 2; the comb needle 1 is directly or indirectly fitted on the rubber 2 to form the Rubber components.

A plurality of raised posts 3 are provided on the back of the rubber skin 2, and the bosses 3 are provided with pinholes 4 for setting the comb needles 1 and a cavity 31 for accommodating the comb 1, and the pinholes 4 penetrate the front of the rubber skin 2 , The cavity 31 is sealed except for the pinhole 4; thus, the comb needle 1 passes through the pinhole 4 from the front of the rubber 2 and is placed in the cavity 31, so that the comb needle 1 is fixed on the rubber 2.

A hook 5 is provided at one end of the comb needle 1, and the needle hole 4 is provided with a clamping piece 6 that can be fitted and fixed in the cavity 31. For example, the length of the cavity 31 is greater than the diameter of the needle hole 4, so that The hook 5 is tightly fitted in the cavity 31 and hooks the clamping piece 6. The diameter of the pinhole 4 is equal to or smaller than the inner diameter of the cavity 31. Since the rubber 2 is made of flexible material, it has a certain degree of elasticity. Therefore, the diameter of the pinhole 4 of the above two specifications can allow the clamping piece 6 to be arranged in the cavity. In the body 31. Preferably, the inner diameter of the cavity 31 matches the outer diameter of the comb needle 1, so that after the comb needle 1 is bent and fitted into the cavity 31, the inner wall of the cavity 31 can exert a force on it. So that its fixing effect is good. In theory, a smaller inner diameter of the cavity 31 can make the fixing effect of the comb needle 1 better, but it will increase the difficulty of fitting the hook 5 of the comb needle 1 into the cavity 31, while a larger cavity 31 can reduce It is difficult for the hook 5 of the comb needle 1 to fit into the cavity 31, but it will weaken the fixing effect of the comb needle 1 in the cavity 31; therefore, the relative specifications of the two need to be appropriately set. In addition, the hook 5 can be inserted into the cavity 31 together with the clamping piece 6 after it is hooked. This way of assembling the comb needle 1 and the rubber 2 is very easy to implement.

For the comb needle 1, it is softer than the traditional plastic comb needle to overcome the problem of hair knotting. Therefore, it can be made of nylon yarn or other similar flexible materials, such as nylon with a diameter of 0.7-0.8mm. Silk; one end of the comb needle 1 is bent to form a hook 5, and the other end is formed into a spherical or similar shaped comb needle head; the comb needle head can be formed by thermal processing of nylon filament, or attached to the other end of the nylon filament and other materials form. Compared with the traditional connection method that is clipped to the rubber after injection, the nylon needle is softer, which can overcome the problem of hair knotting caused by the traditional plastic injection molding needle. At the same time, the present invention also solves the problem of This brings the problem of fixing the comb needle 1.

Preferably, the thickness of the rubber 2 in the cross-sectional direction gradually increases from the middle to the edge, that is, the thickness of the middle part is smaller than the thickness of the outer edge part of the rubber 2; this way, on the one hand, the middle part of the rubber 2 can be first contacted and deformed. It is the most flexible and enhances the user experience. On the other hand, it can also facilitate the recovery of the rubber 2 after deformation through the gradually increased elastic force. Practice has shown that the uniform thickness of the rubber, in use, there is a small probability that it will not be able to automatically recover. The above-mentioned design of gradually thickening from the middle to the edge can completely avoid this problem. Preferably, the protruding column 3 and the rubber 2 are integrally formed by injection molding. Generally speaking, the thickness H1 of the center of the main part of the rubber 1 (except the outer edge for rubber fixing) is 1-3mm, and the thickness H2 of the outer edge is 2-5mm. It gradually thickens from the center to the outer edge, but The center to the edge does not require uniform thickening; of course, in theory, stepped thickening is also a feasible solution (for example, the overall thickness is divided into three parts of 1.5mm, 2mm and 3mm from the inside to the outside) . For the thickness of the rubber skin 1, in principle, it can be specifically selected according to product parameters, materials, etc., but the overall requirement of relative thickness difference must be considered.

Preferably, the comb handle 7 includes a placing groove 8 for placing the rubber skin 2, the edge of the placing groove 8 is provided with a transverse clamping groove 9, and the outer edge of the rubber 1 is provided with a clamping block 10 The rubber 1 is installed in the placement groove 8, and the clamping block 10 is snap-fitted with the clamping groove 9 so that the center of the rubber bulges toward the front.

Preferably, the placement groove 8 of the comb handle 7 of the hair comb of the present invention is arranged to be curved toward the back of the rubber 2, that is, the placement groove 8 is arranged along a curved surface.

The hair comb manufactured by this method has an ingenious structure and low overall manufacturing cost, which solves the problem of hair knotting and is easy to clean; at the same time, it completely retains all the functions of the traditional air cushion comb without any reduction. With a special comb handle structure, the comb surface of the comb is flat, and the contact surface with the hair or scalp is larger when combing the hair, which is not available in traditional air-cushion combs.
