Description

Technical Field

[0001] The invention relates to the technical field of hair dyeing equipment, in particular to a comb capable of controlling a hair dyeing area and a hair dyeing head capable of preventing hair dye from adhering to the scalp. Background Art

[0002] At present, hair dyeing is harmful to the body, which is well-known, and this harm can be avoided by not contacting the human skin with the hair dye. In the prior art, there is no tool that can prevent the hair dye from contacting the human skin (mainly the scalp) when hair dyeing. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a hair dyeing head which can control the hair dyeing area and prevent the hair dye from sticking to the scalp in view of the deficiencies of the prior art.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: a comb capable of controlling a hair dyeing area, comprising: a comb tooth plate for hair dyeing, the comb tooth plate being an open structure on both sides, a cavity being arranged in the middle of the comb tooth plate, a baffle being arranged in the cavity, and the baffle dividing the cavity into a main hair dyeing area and an auxiliary hair dyeing area.

[0005] The beneficial effects of the present invention are as follows: by arranging a cavity in the comb teeth, the hair dye is always located in the cavity during the hair dyeing process, thereby preventing the hair dyer from contacting the human skin. The baffle separates the cavity into a main hair dyeing area and an auxiliary dyeing area, and uses the hair dye's own gravity and the affinity between the hair dye and the hair and the hair dyeing head to control the dynamics of the hair dye, maintain a stable physical environment when the hair dye contacts the hair, and ensure uniform dyeing of the hair. When the amount of hair dye entering is too large, the hair dye passes over the baffle and enters the auxiliary dyeing area, which contains excess hair dye. When too much hair dye is attached to the hair, the side wall of the comb teeth scrapes off the excess hair dye and stores it in the auxiliary dyeing area. When there is too little hair dye in the main hair dyeing area, the hair dye stored in the auxiliary dyeing area continues to replenish the hair with hair dye, so that the hair dye attached to the hair when the hair finally leaves the hair dyeing area remains stable and uniform.

[0006] Furthermore, the comb teeth include: a front column, a rear column, a top beam and a bottom beam, the front column, the rear column, the top beam and the bottom beam are sequentially connected to form the cavity, and the baffle is arranged on the top beam.

[0007] The beneficial effect of adopting the above further scheme is: the setting of the top crossbeam isolates the hair dye from the scalp to prevent the hair dye from contacting the human skin. Under the action of the baffle, the hair dye detours downward to reduce the pressure of the hair dyer to normal pressure, and the flow state of the hair dye is controlled by the gravity of the hair dye itself and the affinity of the hair dye with the hair and the dye head, so that the comb teeth can adapt to pressurized hair dyes such as pastes, mousses and aerosols, preventing the hair dye from splashing onto the human skin under pressure, thereby improving the reliability of the comb teeth.

[0008] Furthermore, the area between the front column and the baffle is a main hair dyeing area, and the area between the rear column and the baffle is an auxiliary dyeing area.

[0009] The beneficial effect of adopting the above further scheme is: by setting a cavity in the comb teeth, the hair dye is always located in the cavity during the hair dyeing process, preventing the hair dyer from contacting the human skin. The baffle separates the cavity into a main hair dyeing area and an auxiliary dyeing area, and uses the hair dye's own gravity and the affinity of the hair dye with the hair and the hair dyeing head to control the dynamics of the hair dye, maintain a stable physical environment when the hair dye contacts the hair, and ensure uniform dyeing of the hair. When the amount of hair dye entering is too large, the hair dye passes over the baffle and enters the auxiliary dyeing area, which contains excess hair dye. When too much hair dye is attached to the hair, the side wall of the comb teeth scrapes off the excess hair dye and stores it in the auxiliary dyeing area. When there is too little hair dye in the main hair dyeing area, the hair dye stored in the auxiliary dyeing area continues to replenish the hair with hair dye, so that the hair dye attached to the hair when the hair finally leaves the hair dyeing area remains stable and uniform.

[0010] Furthermore, a channel for circulating hair dye is provided in the front column, a liquid inlet for inputting hair dye is provided on the bottom cross beam, a liquid outlet for outputting hair dye is provided on the side wall of the front column, and the channel is connected to the liquid inlet and the liquid outlet respectively.

[0011] The beneficial effect of adopting the above-mentioned further scheme is as follows: the hair dye is introduced through the liquid outlet, the baffle changes the flow direction of the hair dye, and at the same time the pressure of the hair dyer is reduced to normal pressure, and the flow state of the hair dye is controlled by utilizing the hair dye's own gravity and the affinity of the hair dye with the hair and the dye head, so that the comb teeth can adapt to pressurized hair dyes such as pastes, mousses and aerosols, preventing the hair dye from splashing onto human skin under pressure, thereby improving the reliability of the comb teeth.

[0012] Furthermore, the liquid outlet is arranged corresponding to the baffle.

[0013] The beneficial effect of adopting the above further scheme is: the baffle is used to change the direction of the hair dye flow to the area where the hair passes through the comb teeth, and at the same time the pressure in the hair dye flow is reduced to prevent the hair dye from contacting human skin, thereby improving the stability and reliability of the comb teeth.

[0014] Furthermore, the main hair dyeing area and the auxiliary hair dyeing area are connected below the baffle.

[0015] The beneficial effect of adopting the above further scheme is: by setting a cavity in the comb teeth, the hair dye is always located in the cavity during the hair dyeing process, preventing the hair dyer from contacting the human skin. The baffle separates the cavity into a main hair dyeing area and an auxiliary dyeing area, and uses the hair dye's own gravity and the affinity of the hair dye with the hair and the hair dyeing head to control the dynamics of the hair dye, maintain a stable physical environment when the hair dye contacts the hair, and ensure uniform dyeing of the hair. When the amount of hair dye entering is too large, the hair dye passes over the baffle and enters the auxiliary dyeing area, which contains excess hair dye. When too much hair dye is attached to the hair, the side wall of the comb teeth scrapes off the excess hair dye and stores it in the auxiliary dyeing area. When there is too little hair dye in the main hair dyeing area, the hair dye stored in the auxiliary dyeing area continues to replenish the hair with hair dye, so that the hair dye attached to the hair when the hair finally leaves the hair dyeing area remains stable and uniform.

[0016] Furthermore, the comb teeth are made of plastic or metal.

[0017] The beneficial effect of adopting the above further solution is that the comb teeth are made of plastic or metal, which improves the stability and reliability of the comb teeth and extends the service life of the comb teeth.

[0018] In addition, the present invention also provides a hair dyeing head for preventing hair dye from sticking to the scalp, which comprises: a cover body for being screwed onto the hair dye bottle, a pair of isolation plates for preventing hair dye from sticking to the scalp, and a plurality of comb teeth for controlling the hair dyeing area as described in any one of the above items, the pair of isolation plates and the plurality of comb teeth are both mounted on the cover body, and the plurality of comb teeth are located between the pair of isolation plates.

[0019] The beneficial effects of the present invention are as follows: the comb teeth at both ends of a plurality of comb teeth pieces are added with a partition plate to form a closed hair dyeing area with a front column, a rear column, a top crossbeam and a bottom crossbeam. The hair dyeing area is divided into a main hair dyeing area and an auxiliary hair dyeing area by a baffle on the top crossbeam. The top crossbeam and the partition plate seal the comb teeth at the top and the side of the hair dyeing head to prevent the hair dye from directly contacting the scalp. A path for the dyed hair to pass through is formed between the comb teeth. The width between the comb teeth is controlled by the surface tension of the hair dye so that the hair dye stays near the crossbeam and does not fall to the scalp. By arranging a cavity in the comb teeth piece, the hair dye is always located in the cavity during the hair dyeing process to prevent the hair dyer from contacting the human skin. The baffle separates the cavity into the main hair dyeing area and the auxiliary hair dyeing area, and the dynamics of the hair dye are controlled by the self-gravity of the hair dye and the affinity of the hair dye with the hair and the hair dyeing head, so as to maintain a stable physical environment when the hair dye contacts the hair, thereby ensuring uniform hair dyeing. When the amount of hair dye entering is too large, the hair dye goes over the baffle and enters the auxiliary dyeing area, which contains the excess hair dye. When too much hair dye is attached to the hair, the side wall of the comb teeth scrapes off the excess hair dye and stores it in the auxiliary dyeing area. When the amount of hair dye in the main dyeing area is too small, the hair dye stored in the auxiliary dyeing area continues to add hair dye to the hair, so that the hair dye attached to the hair is stable and uniform when the hair finally leaves the dyeing area.

[0020] Furthermore, the plurality of comb teeth are arranged parallel to each other, a first gap for hair movement is provided between the plurality of comb teeth, the bottom crossbeam is connected to the cover body, and the liquid inlet on the comb teeth is connected to the cover body.

[0021] The beneficial effect of adopting the above further scheme is: the comb teeth at both ends of the plurality of comb teeth pieces are added with a partition plate to form a closed hair dyeing area with the front column, the rear column, the top crossbeam and the bottom crossbeam. The baffle on the top crossbeam is used to separate the hair dyeing area into a main hair dyeing area and an auxiliary hair dyeing area. A path for the dyed hair to pass through is formed between the comb teeth.

[0022] Furthermore, the isolation plate is a plate-shaped structure, and a second gap for hair to move is provided between the isolation plate and the outermost comb teeth.

DETAILED DESCRIPTION

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a comb capable of controlling a hair dyeing area, comprising: a comb tooth piece 1 for hair dyeing, the comb tooth piece 1 being an open structure on both sides, a cavity 2 being arranged in the middle of the comb tooth piece 1, a baffle 3 being arranged in the cavity 2, the baffle 3 dividing the cavity 2 into a main hair dyeing area 4 and an auxiliary hair dyeing area 5.

[0036] The beneficial effects of the present invention are as follows: by arranging a cavity in the comb teeth, the hair dye is always located in the cavity during the hair dyeing process, thereby preventing the hair dyer from contacting the human skin. The baffle separates the cavity into a main hair dyeing area and an auxiliary dyeing area, and uses the hair dye's own gravity and the affinity between the hair dye and the hair and the hair dyeing head to control the dynamics of the hair dye, maintain a stable physical environment when the hair dye contacts the hair, and ensure uniform dyeing of the hair. When the amount of hair dye entering is too large, the hair dye passes over the baffle and enters the auxiliary dyeing area, which contains excess hair dye. When too much hair dye is attached to the hair, the side wall of the comb teeth scrapes off the excess hair dye and stores it in the auxiliary dyeing area. When there is too little hair dye in the main hair dyeing area, the hair dye stored in the auxiliary dyeing area continues to replenish the hair with hair dye, so that the hair dye attached to the hair when the hair finally leaves the hair dyeing area remains stable and uniform.

[0037] The present invention extends the function of hair dyeing comb teeth to achieve the purpose of preventing hair dye from contacting human skin. Different types of hair dyes (paste, mousse and aerosol) are slightly different, but their main structural forms are the same. The comb teeth at both ends of the comb tooth group (i.e., a combination of multiple comb tooth pieces) are added with isolation plates to form a closed hair dyeing area with the front column, the rear column, and the cross beam (i.e., the top cross beam and the bottom cross beam). The baffle on the cross beam is used to separate the hair dyeing area into a main hair dyeing area and an auxiliary hair dyeing area. A path for the dyed hair to pass through is formed between the comb teeth.

[0038] When dyeing hair, hair dye (including paste, currently popular mousse and spray aerosol) is introduced into the nearly closed hair dyeing area through the liquid outlet, and the baffle is used to change the direction of the hair dye flow to the area between the hair teeth, and the pressure in the hair dye flow is reduced at the same time. The baffle divides the hair dyeing area into two parts: the main hair dyeing area, which is the area between the baffle and the front column. The main hair dyeing area is the main area for hair dyeing. The dynamics of the hair dye are controlled by gravity and the affinity between the hair dye and the hair and the hair dyeing head, and a stable physical environment is maintained when the hair dye contacts the hair, ensuring uniform hair dyeing. When the amount of hair dye entering is too large, the hair dye will pass over the baffle and enter the auxiliary dyeing area. The auxiliary dyeing area is the area between the baffle and the rear column. The auxiliary dyeing area contains excess hair dye. When the rear column attaches too much hair dye to the hair, it scrapes them off and stores them in the auxiliary dyeing area. When the hair dye in the main dyeing area is too little, the hair dye stored in the auxiliary dyeing area continues to add hair dye to the hair, so that the hair dye attached to the hair remains stable when the hair finally leaves the dyeing area.

[0039] The solution of the present invention is to solve the above problems from a completely new perspective. When dyeing hair, the hair dye (including paste, currently popular mousse and future aerosol) is first introduced into a nearly closed hair dyeing area, which plays a decompression role at the same time. The flow state of the hair dye is controlled by gravity and the affinity between the hair dye and the hair and the hair dyeing head, so that the hair dye is evenly attached to the hair. The rear column is used to scrape the excessive hair dye that may be attached to the hair back to the hair dyeing area. It can achieve the effect of minimizing the contact of hair dye with human skin and reducing the damage of hair dyeing, and at the same time make the hair dye evenly attached to the hair, and the color difference after hair dyeing can be ignored. At present, there is no complete alternative solution. There is only a similar solution for paste hair dye, but this solution is not suitable for mousse and aerosol hair dye, and its solution has too strict requirements on the supply rate of hair dye.

[0040] 1. Use the comb teeth at both ends of the comb group and the isolation plate to form a closed hair dyeing area with the front column, rear column, crossbeam and interface. Or use part of the structure to separate the hair dyeing area. 2. The hair dye is introduced through the liquid outlet, and the baffle is used to change the direction of the hair dye flow, and the pressure is reduced to normal pressure at the same time. The flow of the hair dye is controlled by gravity and the affinity of the hair dye with the hair and the hair dye head. 3. Use the baffle on the crossbeam to divide the hair dyeing area into the main hair dyeing area and the auxiliary hair dyeing area. 4. Use the crossbeam to isolate the hair dye from the scalp. 5. Use the surface tension of the hair dye to control the width between the comb teeth so that the hair dye stays near the crossbeam and does not fall to the scalp.

[0041] like Figure 1 and Figure 2 As shown, further, the comb teeth 1 include: a front column 6, a rear column 7, a top crossbeam 8 and a bottom crossbeam 9, the front column 6, the rear column 7, the top crossbeam 8 and the bottom crossbeam 9 are sequentially connected to form the cavity 2, and the baffle 3 is arranged on the top crossbeam 8.

[0042] The beneficial effect of adopting the above further solution is that the top crossbeam is arranged to isolate the hair dye from the scalp, preventing the hair dye from contacting the human skin, and the hair dye is detoured downward under the action of the baffle (the downward here refers to Figure 1 The area below the baffle in the structure shown (the area is in the cavity and below the baffle) reduces the pressure of the hair dyer to normal pressure, and uses the gravity of the hair dye and the affinity of the hair dye with the hair and the dye head to control the flow state of the hair dye, so that the comb teeth can adapt to pressurized hair dyes such as pastes, mousses and aerosols, preventing the hair dye from splashing onto human skin under pressure, thereby improving the reliability of the comb teeth.

[0043] Wherein, the outer side wall of the front column can be a tapered structure, which is the same as a daily comb, so as to be convenient for combing hair. In addition, the shape of the cavity can be a rectangle, square, triangle, circle or rhombus.

[0044] like Figure 1 and Figure 2 As shown, further, the area between the front column 6 and the baffle 3 is the main hair dyeing area 4, and the area between the rear column 7 and the baffle 3 is the auxiliary dyeing area 5.

[0045] The beneficial effect of adopting the above further scheme is: by setting a cavity in the comb teeth, the hair dye is always located in the cavity during the hair dyeing process, preventing the hair dyer from contacting the human skin. The baffle separates the cavity into a main hair dyeing area and an auxiliary dyeing area, and uses the hair dye's own gravity and the affinity of the hair dye with the hair and the hair dyeing head to control the dynamics of the hair dye, maintain a stable physical environment when the hair dye contacts the hair, and ensure uniform dyeing of the hair. When the amount of hair dye entering is too large, the hair dye passes over the baffle and enters the auxiliary dyeing area, which contains excess hair dye. When too much hair dye is attached to the hair, the side wall of the comb teeth scrapes off the excess hair dye and stores it in the auxiliary dyeing area. When there is too little hair dye in the main hair dyeing area, the hair dye stored in the auxiliary dyeing area continues to replenish the hair with hair dye, so that the hair dye attached to the hair when the hair finally leaves the hair dyeing area remains stable and uniform.

[0046] like Figure 1 and Figure 2 As shown, further, a channel 10 for circulating hair dye is provided in the front column 6, a liquid inlet 11 for inputting hair dye is provided on the bottom cross beam 9, a liquid outlet 12 for outputting hair dye is provided on the side wall of the front column 6, and the channel 10 is connected to the liquid inlet 11 and the liquid outlet 12 respectively.

[0047] The beneficial effect of adopting the above-mentioned further scheme is as follows: the hair dye is introduced through the liquid outlet, the baffle changes the flow direction of the hair dye, and at the same time the pressure of the hair dyer is reduced to normal pressure, and the flow state of the hair dye is controlled by utilizing the hair dye's own gravity and the affinity of the hair dye with the hair and the dye head, so that the comb teeth can adapt to pressurized hair dyes such as pastes, mousses and aerosols, preventing the hair dye from splashing onto human skin under pressure, thereby improving the reliability of the comb teeth.

[0048] like Figure 1 and Figure 2 As shown, further, the liquid outlet 12 is arranged corresponding to the baffle 3.

[0049] The beneficial effect of adopting the above further scheme is: the baffle is used to change the direction of the hair dye flow to the area where the hair passes through the comb teeth, and at the same time the pressure in the hair dye flow is reduced to prevent the hair dye from contacting human skin, thereby improving the stability and reliability of the comb teeth.

[0050] like Figure 1 and Figure 2 As shown, further, the main hair dyeing area 4 and the auxiliary hair dyeing area 5 are connected below the baffle 3 .

[0051] The beneficial effect of adopting the above further scheme is: by setting a cavity in the comb teeth, the hair dye is always located in the cavity during the hair dyeing process, preventing the hair dyer from contacting the human skin. The baffle separates the cavity into a main hair dyeing area and an auxiliary dyeing area, and uses the hair dye's own gravity and the affinity of the hair dye with the hair and the hair dyeing head to control the dynamics of the hair dye, maintain a stable physical environment when the hair dye contacts the hair, and ensure uniform dyeing of the hair. When the amount of hair dye entering is too large, the hair dye passes over the baffle and enters the auxiliary dyeing area, which contains excess hair dye. When too much hair dye is attached to the hair, the side wall of the comb teeth scrapes off the excess hair dye and stores it in the auxiliary dyeing area. When there is too little hair dye in the main hair dyeing area, the hair dye stored in the auxiliary dyeing area continues to replenish the hair with hair dye, so that the hair dye attached to the hair when the hair finally leaves the hair dyeing area remains stable and uniform.

[0052] like Figure 1 and Figure 2 As shown, further, the comb teeth 1 are made of plastic or metal.

[0053] The beneficial effect of adopting the above further solution is that the comb teeth are made of plastic or metal, which improves the stability and reliability of the comb teeth and extends the service life of the comb teeth.

[0054] like Figures 1 to 8 As shown, in addition, the present invention also provides a hair dye head for preventing hair dye from sticking to the scalp, which includes: a cover body 13 for being screwed on the hair dye bottle, a pair of isolation plates 14 for preventing hair dye from sticking to the scalp, and a plurality of comb teeth for controlling the hair dyeing area as described in any one of the above items, the pair of isolation plates 14 and the plurality of comb teeth 1 are all installed on the cover body 13, and the plurality of comb teeth 1 are located between the pair of isolation plates 14.

[0055] The beneficial effects of the present invention are as follows: the comb teeth at both ends of a plurality of comb teeth pieces are added with a partition plate to form a closed hair dyeing area with a front column, a rear column, a top crossbeam and a bottom crossbeam. The hair dyeing area is divided into a main hair dyeing area and an auxiliary hair dyeing area by a baffle on the top crossbeam. The top crossbeam and the partition plate seal the comb teeth at the top and the side of the hair dyeing head to prevent the hair dye from directly contacting the scalp. A path for the dyed hair to pass through is formed between the comb teeth. The width between the comb teeth is controlled by the surface tension of the hair dye so that the hair dye stays near the crossbeam and does not fall to the scalp. By arranging a cavity in the comb teeth piece, the hair dye is always located in the cavity during the hair dyeing process to prevent the hair dyer from contacting the human skin. The baffle separates the cavity into the main hair dyeing area and the auxiliary hair dyeing area, and the dynamics of the hair dye are controlled by the self-gravity of the hair dye and the affinity of the hair dye with the hair and the hair dyeing head, so as to maintain a stable physical environment when the hair dye contacts the hair, thereby ensuring uniform hair dyeing.

When too much hair dye is attached to the hair, the side wall of the comb teeth scrapes off the excess hair dye and stores it in the auxiliary dyeing area. When the amount of hair dye in the main dyeing area is too small, the hair dye stored in the auxiliary dyeing area continues to add hair dye to the hair, so that the hair dye attached to the hair is stable and uniform when the hair finally leaves the dyeing area.

[0056] The bottom crossbeam can be integrally formed with the cover body, and the cover body is provided with a plurality of cover body liquid outlets, which are connected to the liquid inlets on the comb teeth one by one.
