Description

Technical Field

[0001] This invention provides a comb, and more particularly a comb for applying liquid to hair. Background Technology

[0002] To meet people's various needs for hair nutrition and other benefits, various liquids are often applied to the hair using a comb. There are many existing combs used for applying liquids to hair.

[0003] For example, there is a type of cushion comb with an essential oil container on the comb. The cushion, which serves as the wall of the oil container, has steam vents for liquid evaporation. The comb body has teeth, with the steam vents distributed between the teeth. A heating structure is also included to heat the essential oil in the container, promoting its evaporation and release through the steam vents. During combing, liquids such as essential oils are applied to the hair and scalp. However, with such a comb, the essential oil only emerges from the steam vents, distributing between the teeth and at the base of the teeth. This results in a small amount of essential oil being applied to the hair, and the need for heating to activate the oil, leading to poor application results.

[0004] Another type of multi-functional oil comb has an oil-filled chamber within its body. Several hollow comb teeth connect to this chamber, with ball bearings at the ends or through-holes on the sidewalls. The essential oil flows through the hollow chambers to the ends of the teeth and exits through the gaps between the teeth and the ball bearings, either for applying to the scalp or for applying to the hair. With this type of comb, the amount of oil flowing out through the hollow teeth is difficult to control. If there is liquid in the oil-filled chamber but the comb is not used immediately, the oil can easily leak out through the hollow chambers and through-holes, causing contamination and waste.

[0005] To ensure the smooth flow of essential oils, existing combs typically employ hollow teeth, with a liquid reservoir connected to the teeth. Some use a pump, others a vibration device, and still others heating to allow the essential oil to flow from the hollow teeth. When combing the hair with this oil-filled comb, the oil flows out from through holes on the side walls of the teeth or from outlets at the tips, achieving the purpose of applying the oil to the hair or scalp. These structures are all relatively complex and share a common problem: the amount of essential oil flowing from the tips or sides of the teeth is difficult to control. Utility Model Content

[0006] The purpose of this invention is to improve upon the shortcomings of the existing technology and provide a comb for applying liquid to hair. It can connect the liquid storage tank on the comb and the comb teeth through capillary tubes, so that the liquid in the liquid storage tank is delivered to the comb teeth and air is delivered to the liquid storage tank. It can not only achieve the purpose of applying liquid to hair through the comb, but also meet the need to apply liquid to hair at any time without having to add liquid while applying it.

[0007] A further objective of this invention is to provide a comb for applying liquid to hair, which can both temporarily store the liquid and prevent the liquid in the reservoir from leaking out when not in use, thus avoiding contamination and waste.

[0008] Another objective of this invention is to provide a comb for applying warm liquid to hair, which has a heating device so that the comb can achieve the effect of hair treatment.

[0009] The objective of this utility model is achieved through the following technical solution:

[0010] Technical solution A is:

[0011] A comb for applying liquid to hair, comprising a comb body and a comb handle.

[0012] The comb body and at least a part of the comb handle, or the comb body and / or the comb handle have a hollow structure to form a liquid storage tank. The comb body is provided with comb tooth holes that communicate with the liquid storage tank. Liquid-guiding comb teeth made of loose material are sealed and inserted into each comb tooth hole. At least one end of a portion of the liquid-guiding comb teeth is in the liquid storage tank, and the other end of all the liquid-guiding comb teeth extends out of the comb tooth holes to form comb teeth or part of comb teeth of this comb. The liquid storage tank is provided with a sealed liquid injection structure.

[0013] Preferably, an oil core made of a porous material is provided in the liquid storage tank, and one end of each of the liquid guiding combs in the liquid storage tank is in contact with the oil core.

[0014] Preferably, the oil core is located on one side of the liquid storage chamber opposite to the comb teeth, and the liquid guiding comb teeth abut against the oil core. Alternatively, the oil core is located inside the liquid storage chamber, and the ends of the liquid guiding comb teeth pass through the oil core.

[0015] Preferably, a portion of the oil core extends outside the liquid storage chamber through an oil core hole or oil core slot provided on the comb body, and comes into contact with at least a portion of the liquid guiding comb teeth.

[0016] Preferably, the oil core can be filled in the liquid storage tank at the position corresponding to the comb tooth hole.

[0017] Preferably, a liquid-gathering ring is also provided in the liquid storage tank, which presses against the oil core.

[0018] Specifically, the liquid-aggregating ring can be several circular rings or a spiral, supported in the liquid storage tank. One side of the liquid-aggregating ring abuts against the side wall of the liquid storage tank with comb-like holes, and the other side abuts against the opposite side wall of the liquid storage tank. The oil core is located in the middle of the circular rings or spiral of the liquid-aggregating ring. The liquid-aggregating ring can compress the oil core to adjust the amount of liquid absorbed within it.

[0019] Technical Solution B:

[0020] A comb for applying liquid to hair, comprising a comb body and a comb handle.

[0021] The comb body and / or the comb handle have a hollow internal structure to form a liquid storage tank. The comb body is provided with comb tooth holes, at least a portion of which are isolated from the liquid storage tank. One end of a liquid-guiding comb tooth made of loose material is inserted into each comb tooth hole, and the other end of all the liquid-guiding comb teeth extends out of the comb tooth hole to form a comb tooth or part of a comb tooth. The liquid storage tank is provided with a sealed liquid injection structure.

[0022] The liquid storage tank has a liquid outlet, and a sleeve made of impermeable material is sealed over the outlet. An oil core groove is provided on the comb body, communicating with the comb tooth holes. The two ends of the sleeve connect the liquid storage tank and the oil core groove. An oil core is placed in the sleeve, with one end inserted into the liquid storage tank and the other end inserted into the oil core groove and in contact with the liquid-guiding comb teeth. Alternatively, the two ends of the sleeve connect the liquid storage tank and the outer surface of the comb body. An oil core is placed in the sleeve, with one end inserted into the liquid storage tank and the other end extending onto the outer surface of the comb body and contacting the exposed root of the liquid-guiding comb teeth inserted into the comb tooth holes, thereby transferring liquid to the liquid-guiding comb teeth. This achieves the transfer of liquid from the storage tank to the liquid-guiding comb teeth through the capillary structure of the oil core.

[0023] In technical solution A, the liquid guiding comb teeth mainly enter the liquid storage tank and directly contact the liquid therein to obtain the liquid. In technical solution B, the liquid guiding comb teeth do not mainly enter the liquid storage tank, but enter the oil core groove and contact the oil core installed therein. One end of the oil core is placed in the liquid storage tank, and the liquid guiding comb teeth indirectly contact the liquid in the liquid storage tank to obtain the liquid.

[0024] In technical solutions A and B, preferably, an oil film may also be included.

[0025] The oil film is disposed on the outer surface of the comb body on the same side as the comb teeth; the oil film is in contact with the root of at least a portion of the liquid-guiding comb teeth.

[0026] Preferably, one or both ends and / or a portion of the oil film can extend into the liquid storage chamber through oil film holes or slits provided on the comb body to contact the liquid therein and to contact the oil core therein.

[0027] In technical solution B, the oil film can also extend into the oil core groove and contact the oil core.

[0028] The oil film is inserted into the liquid storage tank or the oil core groove and contacts the oil core. The part of the oil film outside the liquid storage tank can be connected with the liquid guide comb to obtain liquid. The part in contact with the oil core and / or the part placed in the liquid storage tank can also obtain liquid through the oil core and / or directly from the liquid storage tank.

[0029] The oil film can be a sheet made of porous and loose material, covering the outer surface of the comb and located at the root of the liquid-guiding comb teeth. The sheet-like oil film is made of a flexible or rigid material with a capillary structure, with holes provided on it, and is attached to the liquid-guiding comb teeth through the holes and placed at the root of the liquid-guiding comb teeth.

[0030] The flexible sheet-like oil film can be a sponge sheet used on absorbent mops, or a sponge, foam, fiber rod, or non-woven fabric. A rigid oil film can be, for example, a wood chip processed from a relatively loose and soft wood. Loose and soft wood refers to wood with loose wood fibers, also known as softwood, such as poplar or pine. The wood chip is bent into an arc shape to form the outer surface of the comb.

[0031] The oil film can also be a rod-shaped oil film made of porous and loose material, such as a cotton swab, a liquid-guiding cotton core used in atomizers, or a fiber rod used in aromatherapy bottles. A groove is provided on the comb body on the same side as the liquid-guiding comb teeth, communicating with a liquid storage tank. The oil film, which fixes the rod body, is embedded in this groove so that the side of the oil film located at the bottom of the groove contacts the liquid in the storage tank. The oil film can also absorb liquid by contacting the oil core and then connecting to the storage tank through the oil core. The other side of the oil film is located above the outer surface of the comb body and positioned between the liquid-guiding comb teeth. Sheet-shaped and rod-shaped oil films can also be made from certain sponges with strong liquid absorption capacity or foam used to make mops.

[0032] For example, the foam can be PVA (polyvinyl alcohol) foam; the main materials for absorbent mop heads include polyvinyl alcohol foam, PVA material, and microfiber.

[0033] The oil film on the rod, combined with the comb of the single row of liquid-guiding teeth, can be located on one or both sides of the liquid-guiding teeth;

[0034] The oil film on the rod body, and multiple oil films are arranged parallel to each other between or on the sides of each row of liquid guide comb teeth.

[0035] The thickness of the oil film can be 1-3 mm.

[0036] The function of the oil film is to apply liquid to the hair from another dimension. The comb teeth penetrate the hair to apply the liquid, while the oil film is applied by sticking to the surface of the hair.

[0037] In technical solutions A and B, preferably, a hollow tube extends outward parallel to the outer port of each of the comb teeth holes in the comb body. The outer end of the hollow tube can be closed or open. A slit is opened on the side wall of each hollow tube. The portion of the liquid-guiding comb teeth outside the comb body is placed inside the hollow tube, or it can extend out from the opening. The maximum width of the comb teeth corresponding to the slit is greater than the width of the hollow tube, so that the portion of the liquid-guiding comb teeth is exposed from the slit on the side.

[0038] The exposed, porous material of the comb teeth can be irregularly shaped.

[0039] Preferably, the end of the liquid-guiding comb tooth placed inside the liquid storage chamber is a pointed tip, and the section passing through the comb tooth hole is a columnar section.

[0040] Preferably, the gap extends to one-fifth to four-fifths of the lower length of the hollow tube.

[0041] Preferably, the gap is a V-shaped hole that is wider near the base of the comb teeth and narrower away from the base of the comb teeth, or a rectangular hole that is uniform in size from top to bottom.

[0042] More specifically, there are two V-shaped or rectangular holes, which are respectively set on the left and right sides of each liquid guide comb tooth.

[0043] The liquid-guiding comb teeth of this structure are protected by hollow tubes, which improves their strength and rigidity. Because of the support and protection of the hollow tubes, the liquid-guiding comb teeth of this structure can be made of fiber materials with greater porosity but also more flexible. Although the contact area between the liquid-guiding comb teeth and the hair is reduced, the greater porosity can significantly increase the internal liquid content, and it can still have a good coating effect on the hair.

[0044] When a porous material with higher porosity is selected, in order to improve the rigidity of the comb teeth, the liquid-guiding comb teeth can also be composed of a porous material and a rigid material with higher rigidity.

[0045] Specifically, the rigid material can be inserted inside the porous material. One example is that the liquid-guiding comb teeth include a rigid material core and a porous material liquid-guiding comb tooth sleeve. The core is, for example, made of plastic or metal, and the liquid-guiding comb tooth sleeve is fitted over the core. Alternatively, the liquid-guiding comb teeth include a porous material comb tooth core and a clamping cap made of rigid material. The clamping cap has a cap top, and at least two clips extend below the cap top. The clamping cap is inserted into the liquid-guiding comb teeth exposed on the comb body. The lower ends of the clips either clamp the side walls of the liquid-guiding comb teeth or are fixed to the comb body, with the sides of the liquid-guiding comb teeth exposed. The lower root of the porous material liquid-guiding comb teeth directly or indirectly contacts the liquid reservoir, and its sides are exposed outside the rigid comb tooth sleeve for contact with the hair during combing.

[0046] The aforementioned rigid material refers to a material that does not have a capillary structure, and its stiffness and strength are greater than those of a porous material that has a capillary structure.

[0047] Preferably, the exposed portion of the liquid-guiding comb teeth is columnar, with a conical shape only at the tip; or it has a spindle-shaped or bullet-shaped tip.

[0048] Preferably, the shape of the liquid-guiding comb teeth can also be a rotating body with a thicker section at the root and a thinner section at the end, with the thicker and thinner sections transitioning through a curve, and its shape can resemble that of a baby pacifier.

[0049] In technical solution B,

[0050] Regarding the liquid outlet

[0051] Preferably, the outlet can be located on the end face of the liquid storage tank or on the side of the liquid storage tank.

[0052] Regarding the sleeve, preferably, the sleeve extends into the liquid storage tank, and the distance from the inlet of the sleeve to the outlet of the liquid storage tank is greater than or equal to half the corresponding depth of the liquid storage tank, that is, the inlet end of the sleeve extending into the liquid storage tank is further away from the outlet.

[0053] Preferably, the inlet is closer to the tail of the comb handle.

[0054] Preferably, the inlet is located at the middle of the corresponding side of the liquid storage tank.

[0055] With this sleeve design, the liquid in the storage tank will not flow out of the sleeve without capillary action, thus preventing pollution and waste, no matter where the comb is placed, as long as the liquid level in the storage tank is lower than at least one of the inlet and outlet of the sleeve.

[0056] Furthermore, the liquid storage chamber is a cylindrical cavity, and the sleeve is arranged perpendicular or parallel to the length direction of the cylindrical cavity.

[0057] If the sleeve is perpendicular to the axis of the cylindrical cavity, i.e., the outlet is located on the side of the storage chamber, then the outlet of the sleeve is located at the middle position along the length of the cylindrical cavity or closer to the tail of the comb handle. The distance between the inlet and outlet of the sleeve inserted into the storage chamber is greater than half the width of the end face of the cylindrical cavity. Accordingly, during use, the liquid storage capacity in the storage chamber does not exceed half the volume of the cylindrical cavity.

[0058] If the sleeve is parallel to the axis of the cylindrical cavity, i.e., the outlet is located on the end face of the storage tank, the outlet of the sleeve can be located in the middle or off-center along the width direction of the end face of the cylindrical cavity. The distance between the inlet and outlet of the sleeve inserted into the storage tank is greater than or equal to half the length of the cylindrical cavity. Similarly, the liquid storage capacity in the storage tank does not exceed half the volume of the cylindrical cavity.

[0059] Preferably, the sleeve can be made of plastic, rubber, or wood.

[0060] In the aforementioned technical solutions A and B, regarding the liquid storage tank,

[0061] At least a portion of the sidewall of the liquid storage tank is transparent, and scale markings are provided on the transparent portion to control the amount of liquid injected and to prevent leakage.

[0062] In technical solution B, regarding the oil core groove,

[0063] The oil core groove is closer to the liquid guide comb teeth than the liquid storage tank.

[0064] Preferably, the oil core groove is higher than the liquid storage tank and closer to the tip of the liquid guiding comb teeth in the longitudinal direction relative to the liquid guiding comb teeth.

[0065] Preferably, the oil core groove is closer to the liquid guiding comb teeth than the liquid storage tank along the length of the comb.

[0066] The oil core groove can be a closed groove with comb-tooth holes in the groove wall, allowing the fluid-guiding comb teeth to insert into the oil core groove and contact the oil core; or it can be:

[0067] Preferably, the oil core groove can be an open groove provided on the comb body, the oil core is embedded in the open groove, and the liquid guiding comb teeth are fixed in the opening of the open groove and one or both sides of them are in contact with the oil core.

[0068] For example, the depth of the open groove of the oil core groove is less than the diameter of the oil core, and the minimum width of one end of the liquid guiding comb is greater than the width of the open groove of the groove grass.

[0069] The guide comb teeth can be inserted into the open groove to press the oil core down into the open groove.

[0070] In technical solutions A and B, preferably, a heating device is further included. This heating device includes a heating plate connected to an electrical circuit, which is connected to a power source or a switch. The power source can be a battery, and a battery compartment is provided on the comb handle and / or comb body. Alternatively, the power source can be an electrical plug. A heating plate fixing groove is provided on the comb, communicating with the comb tooth holes. The heating plate is fixed in the heating plate fixing groove, and the fluid-guiding comb teeth pass through the heating plate in the heating plate fixing groove. When energized, the heating plate contacts the fluid-guiding comb teeth to form a heating structure that heats the area of ​​the fluid-guiding comb teeth that is not exposed outside the comb body and in contact with the hair.

[0071] The heating structure can specifically be: a clamp-type side heating structure and a plug-in type heating structure.

[0072] The clamp-type heating structure is a contact structure between the heating plate and the liquid-guiding comb teeth: a heating sleeve is erected on the heating plate at the position in the comb tooth hole, or a heat-conducting sleeve is fixedly connected, so that the portion of the liquid-guiding comb teeth in the comb tooth hole is placed in the heating sleeve or heat-conducting sleeve, forming a cylindrical heating. The sleeve can be a complete cylindrical structure or an incomplete cylindrical structure.

[0073] The clamp-type heating structure can also be another contact structure between the heating plate and the liquid-guiding comb teeth; the heating plate has one or two vertical plates erected at the position in the comb tooth hole to form a heating side plate or a heat-conducting side plate, so that the part of the liquid-guiding comb teeth in the comb tooth hole contacts the vertical plate, forming a single-sided heating or double-sided heating structure.

[0074] The insert-type heating structure is a contact structure between the heating plate and the liquid-guiding comb teeth: a heating rod is erected on the heating plate at the position corresponding to the comb tooth hole, or a vertical heat-guiding rod is connected; a vertical slot is provided in the liquid-guiding comb teeth; and the heating rod or heat-guiding rod is inserted into the vertical slot to heat the liquid-guiding comb teeth.

[0075] The heating plate and its heating or heat-conducting side plates, rods or sleeves must not be exposed on the outer surface of the comb to avoid the risk of electric shock and burns.

[0076] In the aforementioned technical solutions A and B, regarding the injection structure,

[0077] Preferably, the sealed liquid injection structure may be: opening the liquid injection hole at the end of the comb handle or at the boundary between the comb body and the comb handle, and providing a sealing cap on the liquid injection hole.

[0078] The sealed liquid injection structure can also be configured such that the comb body and comb handle are separate structures, with sealing threads, snap-fit ​​structures, and sealing gaskets provided at the separate structures. Opening this separate structure allows liquid to be added to the liquid reservoir in the hollow comb handle.

[0079] In the aforementioned technical solutions A and B, regarding the liquid-guiding comb teeth,

[0080] Preferably, the cross-section of the liquid-guiding comb teeth made of a porous material is greater than or equal to the cross-section of the comb teeth hole, that is, when the liquid-guiding comb teeth are inserted into the comb teeth hole, the annular gap between them is zero, so that the liquid in the storage tank can only flow out through the liquid-guiding comb teeth made of porous material.

[0081] Preferably, the loose material of the liquid-guiding comb teeth can be the rod body used in the prior art to make fiber pen tips, nylon pen tips, acrylic pen tips or eyebrow pencil leads. By using these existing materials to make the liquid-guiding comb teeth, the liquid output of the comb teeth can be adjusted by changing the size and porosity of the capillaries by adjusting the rod body. Different fiber rods, nylon rods, acrylic rods or eyebrow pencil lead rods can be selected according to the user's needs and the nature of the liquid to be applied.

[0082] Preferably, the porosity of the liquid-guiding comb teeth is between 45-90%, the porosity of nylon material is about 55-90%, and the porosity of fiber material is about 45-85%.

[0083] Preferably, the end of the fluid-guiding comb tooth located inside the fluid reservoir is a pointed tip. The pointed tip inside the fluid reservoir allows the fluid-guiding comb tooth to be easily inserted into the oil core.

[0084] Preferably, the section of the liquid-guiding comb teeth that passes through the comb tooth holes is a columnar section with a diameter of 2-15 mm. The diameter of the columnar section ensures the strength and rigidity of the liquid-guiding comb teeth, as well as the amount of liquid they can adsorb.

[0085] Preferably, the outer end of the liquid-guiding comb teeth is a gradually tapering segment with a slope less than the tip inside the liquid storage tank, and the length ratio of the cylindrical segment to the tapering segment is 1:0.2-0.7. This length ratio further ensures the strength and rigidity of the liquid-guiding comb teeth, while also guaranteeing the smoothness of the comb teeth's insertion and passage through the hair, as well as the contact area with the hair.

[0086] Specifically, the diameter of the columnar segment of the liquid-guiding comb teeth is 2-15 mm and the length is 10-50 mm. The apex angle of the tip located in the liquid storage chamber is 3-15 mm and the apex angle of the tip is 20-60°. The apex angle of the exposed conical segment of the comb teeth is 5-38° and the length is 10-30 mm.

[0087] Preferably, the liquid-guiding comb teeth have a continuously varying irregular shape.

[0088] Preferably, the liquid-guiding comb teeth can be replaced by pulling out the comb tooth holes, thereby changing the porosity of the liquid-guiding comb teeth, that is, the size of the capillaries in the loose material, to adapt to the discharge of different liquids.

[0089] The comb for applying liquid to hair provided by this utility model has the following beneficial effects:

[0090] (1) By inserting liquid-guiding comb teeth made of porous material into the liquid storage tank, the liquid in the liquid storage tank is transported to the entire comb teeth using the capillary principle. Combing the hair with this comb allows you to apply liquid to your hair. At the same time, the air pressure balance in the liquid storage tank is also achieved through the capillary in the porous material such as the liquid-guiding comb teeth. Compared with existing technologies, this comb has sufficient liquid on the liquid-guiding comb teeth for applying to the hair. By using liquid-guiding comb teeth of different properties, it can be suitable for different liquids.

[0091] (2) Furthermore, an oil core is installed in the liquid storage chamber, which can draw at least a portion of the liquid in the liquid storage chamber into the oil core. The liquid guiding comb teeth contact the oil core, which can more evenly conduct the liquid to each liquid guiding comb tooth. The oil core can partially extend out of the liquid storage chamber on the outer surface of the comb body;

[0092] (3) Furthermore, an oil film can be added to make the liquid coating on the outer surface of the comb more uniform and sufficient. The oil film can also extend into the liquid storage tank in part, so that sufficient liquid can be transported outward, providing liquid to the guide comb teeth on the one hand, and filling the outer surface of the comb with liquid on the other hand, which is more conducive to the coating of liquid.

[0093] (4) Adding a liquid-gathering ring in the liquid storage tank can adjust the distribution of liquid in the oil core and in the liquid storage tank in liquid form, thereby adapting to the amount of liquid of different properties discharged from the liquid guide comb and meeting the usage requirements.

[0094] (5) Alternatively, the liquid guide comb teeth can be not inserted into the liquid storage tank, but an oil core can be set in the liquid storage tank. The oil core is led out from the liquid storage tank and contacts the liquid guide comb teeth. The liquid in the liquid storage tank is transferred to the liquid guide comb teeth only through the oil core.

[0095] (6) A heating device can also be installed on this comb to heat the liquid-guiding comb teeth, so that the heated essential oil and other liquids can come into contact with the hair, making the tangled hair smooth and untangling quickly. Compared with the existing technology that heats the liquid storage tank, this comb heats the liquid-guiding comb teeth, which makes the heating or heat-conducting structure closer to the hair, resulting in lower heat loss during the heat conduction process and greater energy saving. It can also make some liquids that are susceptible to low temperature flow better at low temperatures.

[0096] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0113] like Figure 1 and Figure 2 The following is an embodiment 1 of the comb for applying liquid to hair provided by this utility model, which includes a comb body 1 and a comb handle 2. The comb body 1 and the comb handle 2 are sealed together by a connecting structure 3. The interior of the comb body 1 and the comb handle 2 is a hollow structure, forming a liquid storage tank 4. A comb tooth hole 5 is provided on the comb body 1, which communicates with the liquid storage tank 4. One end of a liquid-guiding comb tooth 6 made of loose material is inserted into each comb tooth hole. This end enters the liquid storage tank, and the other end of the liquid-guiding comb tooth extends out of the comb tooth hole 5 to form the comb tooth of this comb. A sheet-like oil film 7 is provided on the outer surface of the comb body on the same side as the side where the liquid-guiding comb tooth 6 is provided. Example 1 is a comb with a single row of teeth. The oil film 7 is a sheet made of a porous and loose material. This sheet can be made of a flexible porous and loose material, such as a cotton sheet, and is fixed to the comb body. The cotton sheet mentioned here and below can be, for example, cotton, such as PVA (polyvinyl alcohol) cotton; or the cotton used in mop heads in the prior art. This material has a better liquid absorption effect than ordinary sponges.

[0114] The oil film 7 can also be made of a porous rigid material, such as a soft wood chip, which is bent into an arc shape and fixed to the comb body. Holes are formed in the sheet-like oil film 7, through which it is secured to the fluid-guiding comb teeth 6 and placed at the root of the teeth. The thickness of the sheet-like oil film can be 1-3 mm.

[0115] Soft wood, also known as softwood, is wood with loose wood fibers, such as poplar and pine.

[0116] The sheet-like oil film 7 absorbs the liquid from the comb teeth and spreads out as it comes into contact with them. Thus, when combing your hair with this comb, not only can the comb teeth 6 apply liquid to the hair, but the liquid absorbed by the oil film 7 can also apply liquid to the hair that comes into contact with the oil film.

[0117] The liquid-guiding comb tooth 6 has a pointed end inside the liquid reservoir, which allows it to easily insert into the comb tooth hole 5. The section of the comb tooth 6 that passes through the comb tooth hole 5 is a cylindrical segment 61 with a diameter of 6 mm. The diameter of the cylindrical segment ensures the strength and rigidity of the liquid-guiding comb tooth. The outer end of the liquid-guiding comb tooth 6 is a tapered segment 62 with a slope less than the gradually tapering tip inside the liquid reservoir. The length of the cylindrical segment is 1.55 times that of the tapered segment. The length of the cylindrical segment is 60 mm, the length of the tapered segment is 29 mm, the apex angle of the pointed end is 28°, and the apex angle of the tapered segment is 7°. This ratio of length between the cylindrical and tapered segments further ensures the strength and rigidity of the liquid-guiding comb tooth, while also guaranteeing the smoothness of insertion and passage through the hair and the contact area with the hair.

[0118] The liquid-guiding comb 6 uses a rod body that is used to make the fiber pen tip, with a porosity of 55%.

[0119] The cross-section of the liquid-guiding comb teeth 6 is larger than that of the comb teeth holes 5. That is, when the liquid-guiding comb teeth are inserted into the comb teeth holes with an interference fit, the annular gap between them is zero, achieving a sealing effect. This allows the liquid in the liquid storage tank 4 to flow out only through the liquid-guiding comb teeth 6 made of porous material. The liquid-guiding comb teeth 6, made of porous material, have a porous internal structure with a large number of capillaries. They can absorb the liquid in the liquid storage tank 4 and diffuse it to the outer surface of the comb teeth outside the liquid storage tank 4 through capillary effect. The sheet-like oil film 7, because it is attached to the liquid-guiding comb teeth, absorbs the liquid from the liquid-guiding comb teeth and then diffuses it.

[0120] The liquid-guiding comb teeth can also be irregularly shaped with continuous variations.

[0121] When using this comb, first unscrew the sealing thread between the comb body 1 and the comb teeth 2. Pour the liquid to be applied to the hair, such as essential oil, into the liquid reservoir 4 of the comb handle 2. Then tighten and seal the comb body 1 and comb teeth 2. The essential oil is distributed throughout the liquid reservoir 4, immersing the tips of the liquid-guiding comb teeth 6 in the oil. The essential oil diffuses through the capillaries on the liquid-guiding comb teeth 6 to the entire comb teeth, and the sheet-like oil film 7 also receives liquid from the liquid-guiding comb teeth. When combing your hair with this comb, the liquid on the surface of the comb teeth is applied to the hair. As the liquid on the outer surface is applied to the hair, the liquid inside diffuses out, continuously replenishing it. The essential oil in the liquid reservoir is discharged from the liquid-guiding comb teeth, creating a pressure difference between the liquid reservoir and the outside. Because the liquid-guiding comb teeth have multiple capillaries connected to the outside, not all capillaries are filled with liquid. Therefore, outside air enters the liquid reservoir through the capillaries without liquid, balancing the pressure and allowing the essential oil in the liquid reservoir to continuously flow to the liquid-guiding comb teeth. This principle is similar to that of existing fountain pen-style brushes with replaceable ink cartridges. Thus, the liquid reservoir continuously delivers liquid to the guide comb teeth for application to the hair, while the sheet-like oil film 7 also comes into contact with the hair, serving the function of spreading the liquid. We can adjust the liquid dispensing speed by selecting guide comb teeth materials with different porosities, thereby changing the size of the capillary gaps and adapting to the different properties of liquids and the user's needs for applying liquid to the hair. For example, using fiber combs has a porosity of 45-85%, while using nylon combs has a porosity of 55-90%.

[0122] In actual product sales, vendors can provide various liquid-guiding comb teeth with different porosities and other properties, allowing users to adapt to different liquids and coating volumes by installing different comb teeth in the comb teeth holes of the comb body. However, in this case, the liquid-guiding comb teeth are inserted into the comb teeth holes with an interference fit, making tooth replacement inconvenient. Therefore, a transition fit structure can be formed between the liquid-guiding comb teeth and the comb teeth holes. Whether it's an interference fit or a transition fit, the liquid in the reservoir exerts pressure on the seal of the comb teeth holes, and liquid may leak out from between the comb teeth and the comb teeth under gravity, causing contamination and waste. This problem is addressed in Example 6 below.

[0123] The rod body for making the liquid-guiding comb teeth 6 is processed into the shape and size of comb teeth through cutting and grinding processes, and then inserted into the comb tooth holes 5 with an interference fit or transition fit for fixation.

[0124] like Figure 3The illustration shows a variation of Embodiment 1, which is a comb with multiple rows of teeth and oil films 7 with different structures. Specifically, a groove is provided on the comb body 1 on the same side as the liquid-guiding comb teeth 6, communicating with the liquid storage tank 4. A rod-shaped oil film 7 is embedded in the groove, with one side of the oil film 7 in the liquid storage tank 4 and the other side located above the outer surface of the comb body 1 and positioned between the liquid-guiding comb teeth 7. This rod-shaped oil film can be combined with a comb with a single row of teeth, but it is better to combine it with a comb with multiple rows of teeth. There can be multiple oil films, arranged parallel to each other between the rows of liquid-guiding comb teeth.

[0125] The difference between the rod-shaped oil film and the aforementioned sheet-shaped oil film is that the sheet-shaped oil film is not directly connected to the liquid reservoir and cannot directly absorb liquid from it. Instead, it absorbs liquid from the guide comb teeth or the oil core. The rod-shaped oil film, on the other hand, is fixed to the comb body, with one side connected to the liquid reservoir or oil core to absorb liquid from it, and the other side exposed between the comb teeth, allowing it to directly absorb liquid from the liquid reservoir. The oil film 7 applies the liquid to the hair through contact with the hair during combing.

[0126] Setting up either a sheet-like or rod-like oil film 7 not only applies liquid to the surface of the hair, but also has other functions: although both the oil film and the liquid-guiding comb teeth are used to apply liquid, the comb teeth apply the liquid by vertically penetrating the hair, while the oil film applies the liquid by horizontally rubbing across the hair. Through the dual functions of the liquid-guiding comb teeth 6 and the oil film 7, working together, the efficiency and quality of applying liquid to the hair can be greatly improved.

[0127] The rod-shaped oil film can be made from open-cell foam materials, such as the cotton swabs used in absorbent mops or the cotton swabs commonly used in humidifiers. The principle by which the oil film draws liquid from the reservoir is the same as that of the liquid-guiding comb, mainly through multiple capillary pores to achieve liquid export and gas import.

[0128] like Figure 4 The illustration shows Embodiment 2 of the hair-applying liquid comb provided by this utility model. The difference between Embodiment 2 and Embodiment 1 is that an oil core 8 made of a loose material such as a cotton sheet, fiber sheet, fiber rod, or non-woven fabric sheet is provided in the liquid storage chamber 4. The oil core 8 is disposed within the liquid storage chamber 4, and the tips of each liquid-guiding comb tooth 6 are inserted into the oil core 8 within the liquid storage chamber 4. In Embodiment 2, the oil core 8 is located on a side of the liquid storage chamber 4 opposite to the comb tooth holes 5, and an oil film 7 is also provided on the outer surface of the comb body 1.

[0129] An oil core 8 is installed in the liquid reservoir 4. The oil core 8 absorbs some of the liquid and distributes it evenly throughout the entire oil core, continuously supplying liquid to the comb teeth. The comb teeth 6 contact the oil core 8, ensuring that each tooth receives approximately the same amount of liquid. This is especially important when there isn't much liquid in the reservoir 4. Without the oil core 8, some comb teeth might have liquid while others might not. Also, many users habitually hold their combs vertically, causing the liquid in the reservoir 4 to accumulate in the corresponding compartment of the comb handle. In this case, the comb teeth 6 wouldn't be fully submerged, making it difficult to apply the liquid effectively to the hair, or requiring a longer waiting period before the comb teeth 6 become wet. With the oil core 8, as long as there is liquid in the reservoir 4, even a small amount, the oil core absorbs the liquid upon contact and retains it for a longer period. The contact between the comb teeth 5 and the oil core 8 ensures that they always absorb liquid and don't dry out. Furthermore, if the liquid in the reservoir is low, even if the oil core is not entirely in contact with the liquid, it will diffuse throughout the entire oil core. This ensures that all the liquid-guiding comb teeth in contact with the oil core 8 can absorb approximately the same amount of liquid. The oil core 8 can be made of materials such as cotton sheets, cotton rods, fiber sheets, fiber rods, or non-woven fabric sheets. A preferred embodiment is that the oil core 8 can be filled with liquid in the reservoir corresponding to the comb tooth holes. In this embodiment 2, some of the capillaries on the liquid-guiding comb teeth are not completely filled with liquid; these can be used as gas channels for pressure balance, ensuring that the liquid in the reservoir can be continuously drained from the liquid-guiding comb teeth.

[0130] like Figure 5 The illustration shows Embodiment 3 of the hair-applying liquid comb provided by this utility model. The comb body 1 and the comb handle 2 are integrally formed, and a liquid storage chamber 4 is formed inside the comb body 1 and the comb handle 2. An improvement is that a liquid inlet 2a is provided at the tail of the comb handle 2, and a sealing cap 2b is screwed onto the liquid inlet 2a. Another improvement of Embodiment 3 is that a liquid-collecting ring 9 is provided in the liquid storage chamber 4. This liquid-collecting ring 9 is a spiral body supported in the liquid storage chamber. One side of the liquid-collecting ring 9 abuts against the side wall of the liquid storage chamber 4 with comb tooth holes 5, and the other side abuts against the opposite side wall of the liquid storage chamber. An oil core 8 is located in the middle of the spiral body of the liquid-collecting ring 9. One end of the liquid-guiding comb tooth 5 inside the liquid storage chamber 4 is inserted into the oil core 8 inserted into the liquid-collecting ring 9.

[0131] The oil core 8, located in the liquid reservoir 4, can absorb some liquid. However, if the oil core is thicker, while the liquid storage capacity is increased, it can easily clog the narrow space of the liquid reservoir 4, isolating the liquid in the reservoir 4 at the comb handle 2 from the comb teeth. The addition of a liquid-gathering ring allows more essential oil to be stored in liquid form in the reservoir when the same amount of essential oil is added. Furthermore, if the comb body is made of transparent plastic, the liquid not absorbed by the oil core in the reservoir can be seen through the transparent comb body. The essential oil absorbed by the oil core is invisible. Therefore, by reducing the volume of the oil core through the liquid-gathering ring, the amount of unobservable essential oil is reduced, allowing the user to determine whether to add more liquid by observing whether there is still flowing liquid in the reservoir.

[0132] like Figure 6 and Figure 7 The image shows Embodiment 4 of the hair-applying liquid comb provided by this utility model. Embodiment 4 is a modification based on Embodiments 1 to 3. In this embodiment, hollow tubes 10 extend parallel outwards from the outer ends of each comb tooth hole in the comb body 1. Slits 11 are formed on the side walls of each hollow tube 10. In this embodiment 4, the slits 11 are V-shaped slits, wider at the top and narrower at the bottom, with two V-shaped holes respectively located on the left and right sides of each liquid-guiding comb tooth. These sides are also the areas where the hair mainly contacts the comb teeth during combing. The portion of the liquid-guiding comb tooth 6 outside the liquid storage chamber 4 is placed inside the hollow tube 10, protruding from the slits, applying the extracted liquid to the hair. Air enters the liquid storage chamber through the capillary pores of the exposed liquid-guiding comb tooth, achieving pressure balance and continuously extracting the liquid. Similar to the previous embodiments, the end of the comb tooth 6 placed inside the liquid storage chamber is a pointed tip, and the section passing through the comb tooth hole is a columnar section. The portion of the comb tooth corresponding to the gap 11 becomes a sheet-like body with a tapered cross-section wider than the width of the hollow tube. This sheet-like body can be irregular, and its width is greater than the thickness of the hollow tube, so that the sheet-like body of the comb tooth is exposed from the gap 11. The gap 11 extends to four-fifths of the lower length of the hollow tube 10.

[0133] In such Figure 6 and Figure 7 In the example shown, the lower end of the hollow tube 10 is closed. In this case, the liquid is applied to the hair by the liquid-guiding comb teeth 6 exposed from the slit 11. Of course, the lower end of the hollow tube 10 can also be open, with the lower ends of the liquid-guiding comb teeth extending out of the lower port of the hollow tube 10.

[0134] Combs with a closed-end hollow tube structure can be used to apply liquids only to the hair, making them suitable for applying liquids to the hair but not to the scalp. Combs with an open-end hollow tube structure can be used to apply liquids to both the hair and the scalp.

[0135] Therefore, the addition of a hollow tube structure allows the comb to be more flexible, and also improves the rigidity and strength of the comb teeth, making it easier to comb thicker, more numerous, and longer hair, and thus having a wider range of applications.

[0136] Furthermore, the liquid-guiding comb teeth 6 of this structure are protected by a hollow tube 10. This improves the strength and rigidity of the comb teeth 6, and because of the support and protection of the hollow tube, a more porous and softer fiber material can be used, such as a fiber material with a porosity greater than 70%. Although the contact area between the liquid-guiding comb teeth and the hair is reduced, the higher porosity still allows for excellent application to the hair, and air can also enter the liquid reservoir through the pores of the capillaries.

[0137] like Figure 8 The present invention provides a 5th embodiment of a comb for applying liquid to hair. In this embodiment, an oil core 8 is provided inside the liquid storage chamber 4, and an oil film 7 is provided on the outer surface of the comb body outside the liquid storage chamber 4. However, the difference from the previous embodiment is that a portion of both ends of the oil film 7 extends into the liquid storage chamber 4 through oil film holes or oil film slits provided on the comb body and contacts the oil core 8 provided therein.

[0138] The oil film 7 extends into the liquid reservoir 4 and comes into contact with the oil core 8 therein, thus forming another liquid output channel and air pressure balance channel in addition to the liquid-guiding comb teeth. Then, through the part of the oil film outside the liquid reservoir that comes into contact with the comb teeth, the liquid applied to the hair by the oil film can be more abundant. In addition, some liquid-guiding comb teeth that cannot be inserted into the liquid reservoir due to the design of the comb can also receive liquid and play the role of applying liquid to the hair because they come into contact with the liquid-filled oil film 7 on the outside.

[0139] Another scheme similar to Embodiment 5 is that a portion of the oil core 8 extends outside the liquid storage chamber 4 through an oil core hole or slit provided on the comb body 1, and comes into contact with the oil film 7. This has a similar effect to the previous embodiment where the oil film 7 extends into the liquid storage chamber 4. Here, the oil core is given an additional function besides liquid storage, namely, the function of liquid transfer.

[0140] The function of the oil core is twofold: firstly, it serves as a liquid storage location to continuously supply liquid to the liquid-guiding comb teeth 6 and / or oil film 7; secondly, it can also serve as a liquid-guiding channel for the liquid-guiding comb teeth 5 and / or oil film 7, being exposed and in contact with the liquid-guiding comb teeth 5 and / or oil film 7. In this case, the liquid-guiding comb teeth and / or oil film do not need to be directly inserted into the liquid storage tank, but instead obtain the liquid from the liquid storage tank through the exposed oil core. As mentioned earlier, due to the design of the comb, the embedding depth of the comb teeth on the comb body is sometimes different. Those comb teeth that are embedded more shallowly, as liquid-guiding comb teeth, may not come into contact with the liquid in the liquid storage tank or the oil core, such as the comb teeth on the side. To solve this problem, this embodiment proposes a modified structure of the oil core, in which a portion of the oil core 8 extends out of the liquid storage tank through an oil core hole or oil core slot provided on the comb body 1, that is, it is exposed outside the comb body and in contact with at least a portion of the liquid-guiding comb teeth. One end of the oil core 8 is in the liquid storage chamber, and the other end protrudes outside the comb body and contacts the liquid guiding comb teeth, so that liquid can be directly supplied to the liquid guiding comb teeth.

[0141] Of course, even if all the comb teeth can be inserted into the liquid reservoir and come into contact with the liquid, the exposed oil core is still a viable option. With the oil core partially exposed, it provides an additional channel to obtain the liquid from the reservoir for applying to the hair, and also provides an additional channel for gas to be added to the reservoir.

[0142] Whether it's part of the oil core 8 extending out of the reservoir and contacting the oil film 7, or part of the oil film 7 extending into the reservoir and contacting the oil core, it's beneficial for the liquid in the reservoir to be output through the capillary structure and applied to the hair.

[0143] like Figure 9 The image shows Embodiment 6 of the hair-applying liquid comb provided by this utility model. Embodiment 6 provides a hair-applying liquid comb, including a comb body 101 and a comb handle 102. The comb body 101 and at least a portion of the comb handle have a hollow internal structure, forming a liquid storage tank 103. The comb body has comb tooth holes 101a, each comb tooth hole 101a being isolated from and not connected to the liquid storage tank 103. The comb body has an oil core groove 101c, which is parallel to the liquid storage tank and connected to the comb tooth holes 101a. One end of a liquid-guiding comb tooth 104 made of a porous material is inserted into each comb tooth hole 101a, and this end is also in the oil core groove. The other end of the liquid-guiding comb tooth 104 extends out of the comb tooth hole 101a, forming the comb teeth of this comb. The liquid storage tank 103 has a sealed liquid injection structure (not shown in the figure).

[0144] A liquid outlet 101b is provided on the wall of the liquid storage chamber, communicating with the oil core groove 101c. A sleeve 105 is sealed and fixed on the liquid outlet 101b. The liquid outlet is located on the side of the liquid storage chamber 103, at the middle position along the length of the cylindrical cavity of the liquid storage chamber. The sleeve 105 is made of a non-fluid-conducting material, such as plastic, rubber, or wood, so that liquid cannot pass through its side wall. One end of the sleeve 105 on the wall of the liquid storage chamber is the outlet 105a, and the other end extends into the liquid storage chamber 103 as the inlet 105b. That is, the liquid in the liquid storage chamber enters the sleeve 105 from the inlet and exits from the outlet into the oil core groove. The distance between the inlet and outlet of the sleeve inserted into the liquid reservoir is greater than half the width of the end face of the cylindrical cavity. An oil core 106 made of a porous material is provided in the sleeve 105. One end of the oil core 106 extends out of the inlet 105b of the sleeve and enters the liquid reservoir 103, while the other end extends out of the outlet 105a of the sleeve 103. The oil core leaving the sleeve 105 enters the oil core groove 101c and contacts each of the liquid-guiding comb teeth inserted in the comb tooth holes 101a. The oil core guides the liquid in the liquid reservoir through capillary tubes to the liquid-guiding comb teeth inserted in the oil core grooves, so that the liquid-guiding comb teeth are coated with liquid for application to the hair.

[0145] Ideally, the oil inserter should be inserted to the bottom of the liquid reservoir 103, with the end of the oil inserter 106 as close as possible to the side wall of the liquid reservoir opposite to the comb teeth. If there is very little liquid in the liquid reservoir, as long as the comb teeth are placed upwards, the bottom of the liquid reservoir 103 will be the lowest point of the liquid level, and as long as there is still a little liquid in the liquid reservoir, it can come into contact with the oil inserter.

[0146] The oil core groove can also be an open groove set on the comb body, with the oil core embedded in the open groove. The liquid-guiding comb teeth are fixed in the opening of the open groove, with one or both sides in contact with the oil core. For example, the oil core diameter is 6mm, and the depth of the oil core groove is 4mm. The end of the liquid-guiding comb teeth is larger than the width of the open groove, and the oil core protrudes outside the opening of the oil core groove. In this case, the root of the liquid-guiding comb teeth is inserted into the opening and is held in place, falling on the oil core. Since the oil core is made of a porous material, it can be compressed. To enhance the tight fit, the liquid-guiding comb teeth can be pressed down by up to 2mm to fit tightly against the oil core.

[0147] Another type of oil core structure does not have an oil core groove on the comb body. Instead, the outlet of the sleeve is located on the outer surface of the comb body. The oil core extending from the outlet of the sleeve extends along the outer surface of the comb body and contacts the exposed roots of the liquid-guiding comb teeth inserted into the comb teeth holes on the comb body, transferring liquid to the liquid-guiding comb teeth. In this case, the oil core, upon reaching the surface of the comb body, not only transfers liquid but also acts as an oil film.

[0148] Whether the hair core is exposed or not is not the key point. In other words, if the hair core is exposed, it forms an oil film strip, which can also be used to apply liquid to the hair. If it is not exposed, it can be applied by simply using the comb teeth, or an additional exposed oil film strip can be added and connected to the hair core to achieve liquid application together with the comb teeth.

[0149] The characteristic of this embodiment 6 is that the liquid-guiding comb teeth do not directly obtain liquid from the liquid storage tank, but rather the liquid is delivered to the comb teeth through an oil core inserted in the liquid storage tank. With this comb structure, the amount of liquid in each comb tooth will not vary due to uneven liquid distribution in the liquid storage tank, resulting in some comb teeth having more liquid than others. Since one end of the oil core is located in only one position in the liquid storage tank, the liquid content on the oil core is relatively uniform. Therefore, the amount of liquid on each comb tooth in contact with the oil core will not differ significantly.

[0150] In this embodiment 6, the liquid guiding comb teeth are not directly inserted into the liquid storage tank, which also serves to prevent the liquid in the liquid storage tank from leaking outward.

[0151] In this embodiment 6, the liquid storage chamber 103 is a cylindrical cavity within the comb body and comb handle.

[0152] If the cannula is perpendicular to the axis of the cylindrical body cavity, see Figure 9 The outlet 101b of the sleeve 105 is located at the middle position along the length of the cylindrical cavity. The distance between the inlet 105b of the sleeve 105 inserted into the liquid storage chamber and the outlet 101b is greater than half the width of the cylindrical cavity. During use, the liquid storage capacity in the liquid storage chamber does not exceed half the volume of the cylindrical cavity.

[0153] Such a comb, when the teeth are facing upwards (e.g.) Figure 9 As shown, when the oil core end in the reservoir is submerged in liquid, it draws liquid through capillary action and transfers it to the guide comb teeth. The liquid will not leak out between the sleeve and the oil core under gravity into the oil core groove, but will instead seep out from between the comb teeth and the guide comb teeth. When using the comb, with the comb teeth facing downwards or diagonally downwards, the liquid level will be lower than the inlet 105b of the sleeve. This prevents liquid in the reservoir from leaking out from the gap between the sleeve and the oil core into the oil core groove.

[0154] If the bushing is 307 (see...) Figure 12Parallel to the axis of the liquid storage chamber 301 in the columnar cavity, i.e., with the outlet located on the end face of the liquid storage chamber, the inlet 307a of the mounting sleeve 307 is located at the midpoint of the width direction of the liquid storage chamber in the columnar cavity. The distance between the inlet 307b of the sleeve 307 inserted into the liquid storage chamber and the outlet 101b (i.e., the inlet 307a) is half the length of the columnar cavity. After the end of the oil core 308 extends out of the sleeve 307 inside the liquid storage chamber, it has a bend facing away from the comb teeth, very close to the side wall of the liquid storage chamber. Similarly, during use, the liquid storage volume in the liquid storage chamber does not exceed half the volume of the columnar cavity. This structure also allows the oil core end to be immersed in the liquid when the comb teeth are placed upwards, drawing liquid through capillary action and transferring it to the liquid-guiding comb teeth, without the liquid leaking out between the sleeve and the oil core under gravity. When using the comb, with the comb teeth facing downwards or diagonally downwards, the liquid level will be lower than the inlet of the sleeve. However, when the comb is held upright, whether the comb handle is facing down or up, the liquid level in the reservoir will be below the inlet 307b of the sleeve 307. In this way, the liquid in the reservoir will not leak out from the gap between the sleeve and the oil core under the action of gravity.

[0155] Combs with this structure will not leak liquid from the outlet on the comb body, whether in use or carried in a bag.

[0156] To facilitate customer use, a transparent window can be installed on the side wall of the liquid storage compartment, allowing customers to see the liquid inside, and graduation markings can be provided. When this comb is sold as a product, the instruction manual, operating guide, and graduation markings on the outer surface of the liquid storage compartment can be used to instruct customers to add the appropriate amount of liquid, thus preventing leakage due to excessive liquid volume.

[0157] There are two other measures to prevent liquid leakage. One is to make the inlet of the sleeve closer to the tail of the comb handle. The other is to make the distance between the inlet and the outlet greater than half the corresponding depth of the liquid storage tank, that is, closer to the tank wall. With this design, more than half the volume of liquid in the liquid storage tank can be held, and the aforementioned leakage is not likely to occur.

[0158] Limiting the liquid volume in the storage tank to no more than half its capacity is mainly to prevent the liquid level from exceeding the inlet of the sleeve when the comb teeth or comb body are facing down, which would lead to leakage. However, if the inlet of the sleeve is closer to the tail of the comb handle, and the distance between the inlet and outlet is greater than half the corresponding depth of the storage tank, that is, closer to the tank wall, then more than half the volume of liquid can be placed in the storage tank without the aforementioned leakage.

[0159] To enhance the strength and rigidity of the fluid-guiding comb teeth, composite fluid-guiding comb teeth can be manufactured.

[0160] One type of composite structure is: such as Figure 9 As shown, a plastic comb sleeve 104a is fitted onto the outer surface of the columnar, loosely shaped liquid-guiding comb teeth 104. The plastic comb sleeve 104a has an upper tip 104a1, and two clips 104a2 extend downward from the upper tip. The plastic comb sleeve 104a is fitted onto the liquid-guiding comb teeth 104, and the lower ends of the clips 104a2d are fixedly connected to the comb body. The lower root of the loosely shaped liquid-guiding comb teeth contacts the oil core, and the side is exposed and in contact with the hair between the two clips.

[0161] Another composite structure is: the liquid guiding comb teeth include a high-strength solid core, which can be made of plastic or metal. A loose material liquid guiding comb tooth sleeve is fitted over the solid core and inserted into the comb tooth hole 101a. The liquid guiding comb tooth sleeve is in contact with the oil core.

[0162] like Figure 10 The illustration shows Embodiment 7 of the hair-applying liquid comb provided by this utility model, which is an improvement on Embodiment 6. A heating device is added, comprising a heating plate 107 connected to an electrical circuit. This electrical circuit is connected to a power source, which can be a battery. Accordingly, a battery box or electrical plug is provided on the comb handle and / or comb body. A switch is provided on the electrical circuit. A heating plate fixing groove 101d is provided on the comb, positioned above the oil core groove 101c. The comb tooth holes 101a pass through the heating plate fixing groove 101d and the oil core groove 101c, such that the liquid-guiding comb teeth inserted into the comb tooth holes contact the oil core in the oil core groove and also contact the heating plate in the heating plate fixing groove. The heating plate 10 is fixed in the heating plate fixing groove 101d and contacts the liquid-guiding comb teeth 104, thus forming a heating structure to heat the liquid-guiding comb teeth. Specifically, the heating plate 107 contacts the side of the liquid-guiding comb teeth in the comb tooth hole 101a, heating the area of ​​the liquid-guiding comb teeth contained inside the comb body and not yet exposed outside the comb body to contact the hair.

[0163] To improve the heating effect of the heating device on the liquid-guiding comb teeth, the heating structure specifically includes a clamp-type side heating structure and a core-type heating structure.

[0164] like Figure 10The diagram shows a clamping heating structure. A heating sleeve is erected in the comb hole 101a of the heating plate 107, or a heat-conducting sleeve is fixedly connected. The heating sleeve, like the heating plate, is equipped with a heating wire, while the heat-conducting sleeve is a sleeve made of a good conductor of heat and is fixed to the heating plate. Thus, the part of the liquid-guiding comb 104 in the comb hole 101a is placed in the heating sleeve or the heat-conducting sleeve, forming a cylindrical heating. Alternatively, the clamping heating structure can be that the heating plate 107 erects one or two vertical plates in the comb hole 101a, forming a heating side plate or a heat-conducting side plate, so that the part of the liquid-guiding comb 104 in the comb hole 101a contacts the one or two vertical plates, forming single-sided heating or double-sided heating.

[0165] like Figure 11 Embodiment 8 of the comb for applying liquid to hair provided by this utility model is an improvement on Embodiment 7. The main difference is that the side-heating structure with a clamp-type heating structure is replaced with the insert-type heating structure. Correspondingly, the positions of the oil core groove and the heating plate fixing groove are changed. On the comb body, the heating plate fixing groove 101d is close to the liquid storage chamber, and the oil core groove 101c is above the heating plate fixing groove 101c.

[0166] like Figure 12The image shows Embodiment 9 of a comb for applying liquid to hair according to this utility model. In Embodiment 9, a liquid storage chamber 301 of the columnar body cavity is disposed in the comb handle 302. The comb body 303 is located at one end of the comb handle and extends in a straight line with the comb handle. A heating plate fixing groove 303a and an oil core groove 303b are provided in the comb body 303, with the heating plate fixing groove at the bottom and the oil core groove at the top, and the two grooves extending parallel to each other along the length of the comb body. Comb tooth holes 303c are provided on the comb body, perpendicular to and intersecting with the heating plate fixing groove 303a and the oil core groove 303b. A heating plate 304 is disposed in the heating plate fixing groove 303a. A heat-conducting rod 305 is disposed on the heating plate 304 corresponding to each comb tooth hole 303c. The lower end of the heat-conducting rod 305 is fixedly connected to the heating plate 304, and the upper end protrudes through the heating plate fixing groove 303c and the oil core groove 303b, protruding from the comb body 303. The liquid guiding comb 306 is a shell made of loose material with a vertical central hole 306a at the lower end. The vertical central hole 306a matches the heat-conducting rod. The lower end of the liquid guiding comb 306 with the central hole is inserted into the heat-conducting rod 305 in the comb hole 303c. The liquid guiding comb 306 passes through the oil core groove 303b and contacts the oil core 308. A liquid outlet 301a is provided at the center of the end face of the liquid storage chamber 301 adjacent to the comb body. A sleeve 307 is fitted on the sleeve, which extends a section within the liquid storage chamber parallel to the length direction of the comb handle. The inlet 307b of the sleeve 307 is located at the middle position in the length direction of the liquid storage chamber. The outlet 307a of the sleeve 307 is connected to the oil core groove 303b. The oil core 308 is installed inside the sleeve 307, extending a section from the inlet 307b into the liquid storage chamber and having a bent section 308a in the direction away from the comb teeth, close to the side wall of the liquid storage chamber in the direction away from the comb teeth. The other end of the oil core 308 extends out from the outlet 307b of the sleeve 307, enters the oil core groove 303b in the comb body, and contacts the liquid guiding comb teeth 306 in the interconnected comb tooth holes 303c to realize the transfer of liquid.

[0167] The lower end of the heat-conducting rod 305 fixed to the heating plate 304 is provided with a flange 305a, and the oil core groove 303b is placed on each flange and maintains a distance from the heating plate fixing groove.

[0168] In Example 9, the liquid reservoir is filled with less than half its volume of liquid. Regardless of how the comb is positioned, no liquid will flow from the sleeve into the oil core groove under gravity and leak out between the liquid-guiding comb teeth and the comb tooth holes. The liquid reservoir is located on the comb handle, allowing for a more compact comb structure and easier portability.

[0169] The addition of a heating device to this comb allows for heating of the liquid-guiding teeth. When the liquid on the teeth is heated, the hair becomes smoother upon contact with the hot liquid, quickly untangling knots and even acting as a hair treatment.

[0170] The combs in Examples 1 to 6 can all be combined with a heating device, that is, a heating plate fixing groove is provided on the comb body, the heating plate is fixed in the fixing groove, the heating plate fixing groove is connected to each comb tooth hole, the liquid guide comb tooth that is inserted into the liquid storage tank or oil core tank at one end passes through the liquid storage tank and then through the heating plate in the heating plate fixing groove, and then passes through the comb body.

[0171] like Figure 13 The image shows Embodiment 9 of the comb for applying liquid to hair provided by this utility model. In Embodiment 9, the shape of the liquid-guiding comb teeth is a rotating body with a thicker section at the base and a thinner section at the tip. The thicker and thinner sections are transitioned by a curve, and its shape can resemble that of a baby pacifier. This shape of comb teeth allows for a larger surface area and a larger contact area with the hair, resulting in a better effect in applying liquid to the hair.

[0172] Alternatively, the exposed portion of the liquid-guiding comb teeth can be columnar, with a conical shape only at the tip; or it can be a spindle-shaped or bullet-shaped tip.

[0173] The diameter of the root of the liquid-guiding comb teeth exposed on the outer surface of the comb body can be 10mm.

[0174] In the comb provided by this utility model, the component is described as being made of a porous material, which is a material with a capillary structure inside.

[0175] like Figure 14 and Figure 15 Embodiment 10 of the present invention provides a comb for applying liquid to hair. Embodiment 10 is based on Embodiment 9, wherein the liquid outlet is located on the end face of the liquid storage chamber, the distance between the inlet of the sleeve inserted into the liquid storage chamber and the liquid outlet is greater than half the length of the cylindrical cavity, and the inlet of the sleeve is closer to the tail of the comb handle. In fact, the closer the inlet is to the bottom of the liquid storage chamber and the closer it is to the handle side, the more liquid can be stored. In this case, even if more than half the volume of liquid is filled into the liquid storage chamber, there will be no leakage.

[0176] The embodiments described above are merely illustrative specific implementations of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
