Description

Technical Field

[0001] The present invention relates to a hairdressing device, which belongs to the technical field of IPC A45D and B26B. Background Art

[0002] Hair needs to be trimmed regularly, which can be achieved through professional hairdressing. Hairdressing is a technique and an art. It includes basic steps such as washing, cutting and blowing. Hair is usually washed before cutting to remove oiliness and static electricity. Hair will be smoother after washing, and can be trimmed more neatly. It can also prevent unwashed hair residue from getting stuck in the trimming tool or causing certain pollution to the washing and cutting tools.

[0003] There are several techniques for trimming, including regular cutting and regular shaving. Shaving is often used for long hair and usually does not produce broken hair in the hair, while cutting will leave broken hair in the hair. After a haircut, it usually takes a few days for the barber to completely clean up the broken hair. During these days, it is necessary to wash the hair and blow dry it with a hair dryer to get used to it in daily life.

[0004] How to clean up the broken hair during the haircut process is a problem that needs to be solved in the current technical field. At present, China Patent Publication No.: CN203210414U discloses a multifunctional hair clipper, whose structure is to set a broken hair box under the hair clipper and a vacuum cleaner connected to the broken hair box through a hose. When the hair clipper trims the hair, the broken hair directly falls into the broken hair box and then enters the vacuum cleaner through the hose. However, there are some problems in use, such as the hair clipper handles the top of the broken hair box, and when the hair clipper is used, it is usually trimmed forward. At certain angles, some broken hair cut by the scissors will be directly ejected, that is, not all broken hair will fall into the broken hair box, but it provides certain technical inspiration.

[0005] In addition, Chinese patent publication number: CN203266698U discloses a new type of hair clipper, which forms a first air duct connected to a hair suction component above the cutter head, and the hair suction component mainly has a negative pressure fan. This technical solution can better solve the problem of the actual falling of broken hair and the direction of being bounced off when it contacts the cutter head.

[0006] In addition, for the above two structures, there is an automatic hair-absorbing waterproof hair clipper disclosed in Chinese Patent Publication No. CN2006277426U, which directly integrates the negative pressure generating mechanism with the hair clipper, and does not need to add an additional negative pressure generating mechanism outside the hair clipper, making the product compact and convenient.

[0007] However, the principle of the above patent still has some shortcomings for different hair qualities and hairstyles, because when the blade head is trimming, sometimes the blade head needs to be at a certain angle to the hair and maintain a certain height distance from the scalp, and the negative pressure cannot be too strong. If it is too strong, the surrounding hair that needs to be trimmed will be more or less sucked close to the blade head, and the hair will be cut by the blade head by mistake, which will affect the shaping of the hairstyle, and some hair fragments will fall into the hair clumps and cover these fragments under the blade head as the blade head moves. When the suction is sucked, or when the blade head moves back to suck again, some of the fragments will be blocked by the hair clumps and the broken hair cannot be sucked away smoothly. Of course, for soft hair, the effect of being sucked away at this point will be more obvious, such as baby hair. Summary of the invention

[0008] The purpose of the present invention is to provide a hair cutting device in order to solve the technical problems that the existing hair cutting needs to be done after shampooing and the broken hair cannot be completely sucked away.

[0009] The technical solution to the problem to be solved by the present invention is as follows:

[0010] A hairdressing device includes a hair clipper, characterized in that: it is also composed of a negative pressure water spray device, the negative pressure water spray device includes a shell composed of a water storage tank, a filter chamber and a sewage tank, the water storage tank is located on the side of the filter chamber, the sewage tank is located below the water storage tank, the water storage tank is connected to a water pump located below the shell through a water pipe, the sewage tank is connected to the filter chamber, the filter chamber is provided with a negative pressure generating mechanism composed of a motor with an impeller, and a filter mechanism located below the negative pressure generating mechanism; a water spray hose at the water outlet end of the water pump is connected to the hair clipper along a corrugated hose corresponding to the shell cover above the negative pressure generating mechanism; a cutter head assembly is provided in the hair clipper, the end of the water spray hose corresponds to the cutter head assembly, and the end cover of the hair clipper covers the periphery of the cutter head assembly.

[0011] A drying mechanism is also provided below the filtering mechanism.

[0012] The filter mechanism can be drawn out from the side of the filter chamber through a drawer mechanism, and the filter mechanism consists of an outer cover and a filter net below.

[0013] The motor of the negative pressure generating mechanism is placed in a frame, and the electric wire supplies power to the motor through the frame. Only the motor shaft is exposed in the frame for installing the impeller.

[0014] The end of the water spray hose is also connected to a spray head assembly, and the water spraying direction of the pressurized water spray hole on the spray head assembly is directly toward the cutter head of the cutter head assembly.

[0015] The housing is placed on a push frame with wheels.

[0016] The shell cover is provided with a placement groove for placing the hair clipper, and the bottom of the groove directly leads to the sewage tank.

[0017] A sewage discharge pipe is arranged on one side of the sewage tank close to the water pump, and a plug cover is arranged at the outlet of the sewage discharge pipe.

[0018] A liquid filling tank is also arranged on the inner wall of the shell above the water storage bin. The water spray hose passes through the liquid filling tank and is then bound with the corrugated hose or sealed and inserted into the corrugated hose until it is arranged at the port of the corrugated hose.

[0019] The beneficial effects of the present invention are as follows:

[0020] By setting a water spray hose corresponding to the cutter head and a corrugated hose connected to the negative pressure generating mechanism, the hair can be cleaned while cutting, and the broken hair is flushed into the water and directly sucked away by the negative pressure. Compared with the negative pressure environment with air as the medium and the obstruction factors such as hair clumps, the efficiency of removing broken hair is higher, and there is no need to clean the hair before cutting. Compared with the traditional haircutting process, it is more streamlined and faster.

[0021] Moreover, during the spray washing process, the cutter head is also cleaned to prevent broken hair and residue from getting stuck in the cutter head or causing certain pollution to the cutter head.

[0022] Furthermore, by adding shampoo into the liquid adding tank, the foam generated by the shampoo has a larger contact area and adhesion efficiency with the broken hair and hair clumps, so that the broken hair and hair clumps can obtain a better cleaning effect and washing effect.

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] See also Figures 1 to 6A hairdressing device, comprising a hairdresser 1, and a negative pressure water spraying device 2, wherein the negative pressure water spraying device 2 comprises a shell composed of a water storage tank 21, a filter chamber 22 and a sewage tank 23, wherein the water storage tank 21 is located at the side of the filter chamber 22, and the sewage tank 23 is located below the water storage tank 21, the water storage tank 21 is connected to a water pump 3 located below the shell through a water pipe 24, the sewage tank 23 is connected to the filter chamber 22, and the filter chamber 22 is provided with a motor 26 with an impeller 25 to generate a negative pressure. The negative pressure generating mechanism comprises a filter mechanism 27 located below the negative pressure generating mechanism; a water outlet 31 of the water pump 3 and a water spray hose 32 are connected and communicated with the hair clipper 1 along the corrugated hose 11 corresponding to the shell cover 4 above the negative pressure generating mechanism; a cutter head assembly 12 is arranged inside the hair clipper 1, and the cutter head assembly includes a cutter head 14 and a motor providing power to the cutter head 14; the end of the water spray hose 11 corresponds to the cutter head assembly 12; the port 13 of the hair clipper 1 covers the periphery of the cutter head assembly 12, and the cutter head assembly is located on the inner side of the port 13 of the hair clipper 1. The negative pressure generated by the negative pressure generating mechanism can generate suction to the periphery of the cutter head assembly through the transmission of the corrugated hose 11.

[0031] In the present invention, the button for controlling the operation of the water pump 3 and the button for controlling the operation of the negative pressure generating mechanism are arranged on the outside of the shell. The two buttons can be used separately or combined together, but the operation of the negative pressure generating mechanism must be before the operation of the water pump 3. If the water pump 3 is operated first, the water sprayed from the hair clipper 1 through the water spray hose 11 will flow out of the hair clipper 1, and when the negative pressure generating mechanism is operated first, the water sprayed from the hair clipper 1 will be sucked into the filter chamber 22 by the negative pressure suction force generated by the negative pressure generating mechanism, ensuring that the water flow will not flow out of the hair clipper 1.

[0032] The implementation principle of the present invention is as follows:

[0033] First of all, when implementing the present invention, some situations should be identified. These situations will cause certain problems when using the present invention, but these problems are the problems to be solved by the present invention and should therefore be excluded.

[0034] For example, some hair to be cut is already very long and bends downward. The port 13 of the entire hair clipper is directly pressed on the hair, and the range corresponding to the port 13 can only be a part of the hair near the root. In this way, when the blade assembly is broken, some hair will remain on the outside of the port 13 and will not be sucked into the filter chamber 22. Therefore, these long hair can be shortened by shaving or pulling the hair to cut the hair, and then the device of the present invention can be used to continue trimming. It should be noted that shaving or pulling the hair to cut the hair will not produce broken hair on the hair clump on the head.

[0035] Another problem is that when in use, the port 13 is small, and fewer hair clumps enter the range of the port 13. This problem can be solved by adjusting the direction in which the cutter head assembly 7 contacts the hair when in use, and can also be solved directly by increasing the size of the port 13. Of course, as the port 13 increases, the pressure value of the corresponding negative pressure must also increase, otherwise the suction force is insufficient, and when water is sprayed on the hair, some water droplets and water flow along the scalp to the cheeks and even the neck.

[0036] It should also be noted that there are many kinds of hairstyles. For those whose hair is not very long, if they just want to cut a flat head or only deal with the short hair on both sides of the ears, they can directly use the device of the present invention. If some other hairstyles are required, then the port 13 of the hair clipper 1 needs to be made of transparent material, so that the contact between the internal blade assembly 12 and the hair clump can be observed through the transparent port, and the shaping of the hairstyle can be well controlled.

[0037] Then, when the present invention is used, the button is turned on to operate the negative pressure generating mechanism and the water pump 3. It can be seen that the water pumped out by the water pump 3 runs through the water spray hose 32 to the port 13 of the hair clipper 1 and sprays toward the cutter head assembly 12, and the negative pressure generated by the negative pressure generating mechanism absorbs the sprayed water flow. When the port 13 of the hair clipper 1 is downward, the water will not flow out of the port 13. Then, the port 13 of the hair clipper 1 is attached to the scalp with relatively short hair, and the cutter head assembly 12 located on the inner side of the port 13 cuts the hair clump. Of course, the hair clump will be wetted by the water flow at this time. At the moment when the upper part of the wetted hair clump is cut off, the wet broken hair will be sucked away along with the water flow by the continuous upward suction force in the corrugated hose 11. Because these broken hair are wetted, The hair is sticky, and the tension on the surface of the water flow will cause the broken hair to adhere to the surface of the water flow or inside the water flow. At this time, the blade of the blade assembly only occupies a part of the size of the port 13, and the rest is filled in the hair clumps that have not been cut. These hair clumps delay the flow rate of part of the water flow. Some broken hair may be stuck to these hair clumps because they are wet, but because the broken hair is sticky, it will only stick to the surface of the hair clumps that have not been cut, and will not fall into the hair clumps. Therefore, as the port 13 is advanced on the scalp and the water flow continues to spray, this part of the broken hair will still be cut off by the blade or directly carried by the water flow and sucked away by the corrugated hose 11, thus ensuring that no broken hair will be left in the whole process.

[0038] The port 13 is a detachable cover 15 .

[0039] The broken hair is sucked into the filter chamber 22 along with the water flow, passes through the gap of the impeller 25 of the negative pressure generating mechanism and is thrown to the side by the spray wheel 25, and then flows along the wall to the filter mechanism 27 below the negative pressure generating mechanism, where the broken hair and the water flow are filtered and separated, and the separated water flows into the sewage tank 23 after passing through the filter mechanism 27. As for the unfavorable factors such as the water flow hitting the impeller and preventing the impeller from transporting, the injected water flow is much smaller than the suction force and the injected water flow is thin, so it will not have too much impact on the impeller. Moreover, when the water hits the impeller, the centrifugal force of the impeller's rotation directly causes the water to flow to the side wall of the outer frame contour of the impeller.

[0040] Further, as a partial improvement to the implementation method, a drying mechanism 28 is further provided below the filtering mechanism 27. After use, the filtering chamber 22 can be dried by the drying mechanism 28. After drying, the broken hair filtered by the filtering mechanism 27 is centrally processed.

[0041] Further, as a partial improvement to the implementation method, the filter mechanism 27 can be pulled out from the side of the filter chamber through a drawer mechanism, and the filter mechanism 27 is composed of an outer cover 27-1 and a filter net 27-2 below. The broken hair that has been filtered out of moisture is small in size, and the filter mechanism 27 can be directly pulled out from the side of the filter chamber 22 to process the broken hair separately and centrally.

[0042] Furthermore, as a partial improvement to the embodiment, the motor 26 of the negative pressure generating mechanism is placed in a frame 29, and the wires are used to power the motor 26 through the frame 29, and the frame 29 only exposes the shaft of the motor 26 for installing the impeller 25. The waterproofing of the frame can provide waterproofing, leakage prevention and protection for the motor 26 and the impeller 25, and can prevent broken hair from entering between the motor 26 and the impeller 25 and causing damage to the impeller 25 and the motor 26.

[0043] Furthermore, as a partial improvement to the embodiment, the end of the water spray hose 32 is also connected to a nozzle assembly 33, and the water spray direction of the pressurized water spray hole on the nozzle assembly 33 is directly toward the cutter head 14 of the cutter head assembly 13. The water spray amount can be reduced by the pressurized water spray hole, and the power of the negative pressure generating mechanism and the negative pressure generated can also be reduced accordingly. Moreover, the water flow sprayed by the pressurized water spray hole has a certain impact force, which has a certain cleaning and massage effect on the scalp and the head.

[0044] Further, as a partial improvement to the embodiment, the housing is placed on a push frame 5 with wheels 51. The push frame 5 is also provided with a push handle 52.

[0045] Furthermore, as a partial improvement to the embodiment, the housing cover 4 is provided with a placement groove 41 for placing the hair clipper, and the bottom of the groove directly leads to the sewage tank 23. After the haircut, there will be some water stains on the wall of the corrugated hose 11, which can be dried through the placement groove 41, and of course, it also provides a place to place the hair clipper 1.

[0046] Further, as a partial improvement to the implementation method, a sewage pipe 30 is provided on one side of the sewage tank 23 near the water pump 3, and a plug cover (not shown) is provided at the mouth of the sewage pipe 30. The accumulated water in the sewage tank 23 can be discharged through the sewage pipe 30, increasing the mobility of the entire device when in use.

[0047] Further, as a partial improvement to the implementation method, a liquid filling tank 6 is further provided on the inner wall of the housing above the water storage bin 21, and the water spray hose passes through the liquid filling tank 6 and then is bound with the corrugated hose 11 or is sealed and inserted into the corrugated hose 11 until the port of the corrugated hose 11 is provided. Shampoo can be added to the liquid filling tank 6.

[0048] In this way, the water finally sprayed out from the water spray hose 11 will contain foam, which increases the contact distance between the broken hair and the hairstyle, isolates the adhesion between the two, and makes the broken hair easier to be sucked away by the suction force. In this process, the shampoo neutralizes the grease on the hair and cleans the dust on the hair and in the hair clumps.

[0049] Of course, the foam of shampoo needs to be washed off for cleaning the hair. At this time, there can be two pipes inside the water spray hose 11. A water pump needs to be added as required. One of the pipes directly sprays clean water, and the other sprays diluted shampoo. The cleaning hose for spraying shampoo and the water spray hose for spraying clean water can be controlled by two servo motors to control the corresponding water pumps, and the spraying is controlled at intervals, such as spraying shampoo for one second and spraying clean water for two seconds. The shampoo spraying and the clean water spraying can also be controlled by buttons outside the shell. The effect of this is that when trimming, only a short period of time of spraying the shampoo is required to ensure that the hair is wetted by the shampoo. The sprayed shampoo itself has a certain water pressure, which will relatively impact and clean the scalp or hair roots. Then, when trimming further or returning the knife to make up for the trimming, the clean water can be controlled to be directly sprayed to clean the hair.
