DETAILED DESCRIPTION

[0023] The utility model is further described below in connection with the drawings.

[0024] It should be noted that if the utility model has involved directional indication language, such as up, down, left, right, front, back, direction language, it is for the convenience of the relative position description of components, not for the absolute position of the relative components, the relative position between components, the movement condition and the like in a certain specific posture, if the specific posture changes, the directional indication also changes accordingly. If the utility model has involved the quantity language, such as "many", "multiple", "several" and the like, it specifically refers to two and more than two. The description of the connection of two components appears in the following text, which refers to the connection of the pipe or opening and the joint structure, and makes the two sealed communication, which can be fixed connection or detachable connection, and the detachable connection includes the connection through the screw joint, the sealed abutment or the interference fit connection.

[0025] As shown in Figure 1 , Figure 2 The utility model provides a hair care comb, including shell body 1, the liquid storage module 2 and the conveying module 3 in shell body 1 and the comb tooth module 4 at one side of shell body 1, the comb tooth module 4 includes liquid guide seat 42 and the comb tooth seat 41 at the periphery of liquid guide seat 42, and the soft tooth 411 is equipped in the bottom of comb tooth seat 41, and the liquid guide comb tooth 44 is equipped in the bottom of liquid guide seat 42, and the liquid guide channel 45 that is communicated with the liquid guide through -hole in the middle part of liquid guide comb tooth 44 is equipped in the top of liquid guide seat 42, and the nutrient solution in liquid storage module 2 is sent into liquid guide channel 45 through conveying module 3, and flows out through liquid guide through -hole, and the liquid guide channel 45 includes multiple flow channels that are sequentially arranged in the order of tree type structure, wherein the liquid outlet end of the upper flow channel is evenly divided into two channels through the shunt tooth 454, and the two channels are communicated with the liquid inlet end of the two flow channels of the next level respectively, and the liquid quantity flowing in the same level flow channel is same, that is, the internal cavity volume is same, for the simplification of design, the same level flow channel can be designed as the structure form that shape, size and length are all same, and the liquid guide through -hole of each liquid guide comb tooth 44 is communicated with the liquid outlet end of at least one last level flow channel. The shunt tooth 454 can adopt linear type, isosceles triangle or circular arc structure and the like, as long as the central line of the axis is aligned with the center line of the liquid outlet end of each level flow channel, wherein the utility model preferably isosceles triangle, and the liquid outlet end of flow channel can be chamfered and widened simultaneously, so that it cooperates with the flow guide surface on both sides of shunt tooth 454, ensures that the channel is not excessively reduced due to shunt tooth 454, and the liquid flow is affected.

[0026] The traditional hair care comb adopts a scheme of one liquid distribution concentrated port simultaneously distributing liquid to multiple liquid guide branch channels around, which is easily affected by the use angle of the hair care comb, makes most of the liquid flow to the low liquid guide branch channel, and thus the liquid spraying is uneven. In comparison, the utility model adopts tree type hierarchical structure to arrange flow channels, makes the liquid gradually shunt under the action of shunt tooth 454, can reduce the influence of use angle, and improve the uniformity of liquid shunt. The specific shunt process is as follows:Figure 2 As shown, according to the structural size of the hair growth comb, six or eight liquid guide combs 44 are usually arranged, and thus the liquid guide channel 45 can preferably be a four-stage flow channel, sequentially including a main flow channel 450, a first-stage branch flow channel 451, a second-stage branch flow channel 452, and a third-stage branch flow channel 453. When the liquid guide combs 44 are eight, each of the liquid guide combs 44 is connected to one of the eight third-stage branch flow channels 453. When the liquid guide combs 44 are six, the two liquid guide combs 44 in the middle are each connected to one of the two third-stage branch flow channels 453, and the remaining liquid guide combs 44 are each connected to one of the remaining third-stage branch flow channels 453. In this way, the liquid spraying range can be controlled as much as possible, and the uniformity of spraying can be improved. After the liquid enters and reaches the liquid outlet end of the main flow channel 450, the liquid is evenly divided into two streams by the branch tooth 454 and enters the two first-stage branch flow channels 451. Then, the liquid reaches the liquid outlet end of the first-stage branch flow channel 451, is again evenly divided into two streams by the branch tooth 454, and enters the two second-stage branch flow channels 452. Then, the liquid reaches the liquid outlet end of the second-stage branch flow channel 452, is evenly divided into two streams by the branch tooth 454, and enters the two third-stage branch flow channels 453. Since the shape, size, and length of the same stage flow channel are the same, the time and flow rate of the liquid through each third-stage branch flow channel 453 are basically the same.

[0027] In the specific manufacturing of the liquid guide channel 45, a groove structure can be arranged on the top of the liquid guide base 42. The comb base 41 and the liquid guide base 42 are fixed on the shell 1 by screws, and a sealing plate 46 is arranged between the top of the liquid guide base 42 and the shell 1, so that the liquid guide channel 45 of the groove structure forms a sealed water channel. The sealing plate 46 is provided with a liquid guide hole 461 corresponding to the liquid inlet end of the main flow channel 450, which is used to connect the liquid storage module 2 and the main flow channel 450. This structure can reduce the manufacturing difficulty of the liquid guide channel 45, improve the accuracy of the size, and directly process the branch tooth 454 on the liquid guide base 42 when forming the groove structure, without the need for additional increase. The liquid guide channel 45 can be easily disassembled and cleaned during subsequent maintenance. The sealing plate 46 can be made of rubber to ensure the sealing effect of the liquid guide channel 45.

[0028] The current hair care comb only controls liquid spraying through a switch when in use, which is easy to cause misoperation, waste nutrient liquid, and cause damage to eyes if not careful. Therefore, in order to improve the safety of use, the utility model increases the safety function, specifically, the liquid guide base 42 and the liquid guide comb tooth 44 are both metal materials, the top of the liquid guide base 42 is provided with a conductive column 47 inserted into the inside of the shell 1, the part of the shell 1 for holding by hand is provided with a conductive tail cover 19, the conductive column 47 and the conductive tail cover 19 are electrically connected with the mainboard 15 in the shell 1, when the conductive tail cover 19 is held by hand and the liquid guide comb tooth 44 contacts the scalp, a closed loop can be formed through the human body, so that the mainboard 15 generates a detection signal, and the conveying module 3 is started when the mainboard 15 has a detection signal. The loop detection function is the prior art, similar to the current electric pen detection function, if the hair care comb is held by oneself to care for the scalp, the hair care comb directly forms a loop through the human body itself, and if the hair care comb is held by oneself to care for the scalp of others, the hair care comb forms a loop through the human body and the ground. Through the setting of the loop detection, only when the switch of the conveying module 3 is started to make it electrified, and the hand contacts the conductive tail cover 19 and the liquid guide comb tooth 44 contacts the scalp, the conveying module 3 can work to spray liquid, and if any one condition is not met, the conveying module 3 will stop working, so as to ensure the safety of use. If it is worried that the liquid guide comb tooth 44 directly contacts the scalp to affect liquid spraying, another comb tooth structure longer than the liquid guide comb tooth 44 can be arranged at the bottom of the liquid guide base 42 to conduct the detection loop, which can make the liquid guide comb tooth 44 have a certain gap with the scalp, facilitating liquid spraying.

[0029] In order to increase the functionality of the hair care comb, the utility model also sets the atomization function, and the switching and use process of the liquid spraying and the atomization function are as follows Figures 3-5As shown, the housing 1 is provided with a receiving cavity 14 on the side away from the comb module 4, the atomization module 5 and the liquid storage module 2 are replaceably installed in the receiving cavity 14, and the liquid guide seat 42 is further provided with an atomization opening 48; when the liquid storage module 2 is placed in the receiving cavity 14, the liquid storage module 2 is connected with the main flow channel 450 through the liquid conveying pipe 33; when the atomization module 5 is placed in the receiving cavity 14, the atomization module 5 is connected with the atomization opening 48 through the atomization channel 462, and the atomization module 5 can send the mist generated by the liquid in the atomization module 5 into the atomization opening 48 under the action of the conveying module 3. In order to avoid the composition pollution caused by the shared channel of liquid spraying and atomization, and affect the hair care effect, the utility model sets a liquid channel and a gas channel in the hair care comb, that is, the liquid conveying pipe 33 and the atomization channel 462, and the two can be installed in the housing 1 in the form of independent pipeline structure, or can be integrally formed with the housing 1. When liquid spraying hair care is needed, the liquid storage module 2 is placed in the receiving cavity 14, and the nutrient solution is sent into the liquid guide channel 45 for spraying by the liquid conveying pipe 33; when atomization hair care is needed, the atomization module 5 is placed in the receiving cavity 14, and the mist is sent into the atomization opening 48 by the atomization channel 462. The conveying module 3 can be provided with two sets of independent conveying mechanisms according to the two hair care modes, for example, a pump is used to convey liquid, a fan is used to blow mist, or a same pump is used to pump liquid and mist.

[0030] The preferred conveying module 3 of the utility model is a gas pump conveying, specifically, the conveying module 3 includes a gas pump 31 and a gas pipe 32 connected with the gas pump 31; the liquid storage module 2 includes a liquid storage bottle 21, one end of the liquid storage bottle 21 is provided with a liquid outlet 22, the other end is provided with an air inlet 23, and the liquid storage bottle 21 is provided with a piston 24; when the liquid storage module 2 is placed in the receiving cavity 14, the liquid outlet 22 is connected with the liquid conveying pipe 33, and the air inlet 23 is connected with the gas pipe 32. At this time, the liquid conveying process is that the gas generated by the gas pump 31 pushes the piston 24 to move to push the nutrient solution between the piston 24 and the liquid outlet 22 in the liquid storage bottle 22 into the liquid conveying pipe 33, and is sprayed from the liquid comb tooth 44, realizing the liquid spraying hair care function. The atomization module 5 includes an atomization bottle 51, the side surface of one end of the atomization bottle 51 is provided with an air outlet 52, the other end is provided with an air inlet 53, and the atomization bottle 51 is provided with an atomizer 54; when the atomization module 5 is placed in the receiving cavity 14, the air outlet 52 is connected with the atomization channel 462, and the air inlet 53 is connected with the gas pipe 32. At this time, the mist conveying process is that the gas pump 31 blows the mist generated at the atomizer 54 into the atomization channel 462, and sprays from the atomization opening 48, realizing the atomization hair care function. The atomizer 54 is a mature product, which is the same as the atomizer in the current electronic cigarette. The oil liquid for atomization is filled between the inner wall of the atomization bottle 51 and the periphery of the atomizer 54, and enters the atomizer 54 by slow permeation.

[0031] For the specific structure of the liquid storage module 2 and the atomization module 5, as shown inFigure 4 、 Figure 5 As shown in the figure, the liquid storage bottle 21 and the atomizing bottle 51 are detachably mounted on the mounting frame 27 through the first sealing ring 25 and the second sealing ring 26 at both ends, facilitating replacement, and the mounting frame 27 is detachably connected with the accommodating cavity 14. The side wall of the accommodating cavity 14 is provided with a liquid outlet hole 141 and an air inlet hole 142 corresponding to the first sealing ring 25 and the second sealing ring 26, which are respectively connected with the liquid outlet 22 and the air inlet 23. The liquid outlet hole 141 and the air inlet hole 142 are respectively connected with the liquid delivery pipe 33 and the air pipe 32. The bottom of the accommodating cavity 14 is provided with an air outlet hole 143, which is connected with the atomizing channel 462. The atomizing channel 462 can be arranged on the liquid guide seat 42 or the sealing plate 46. When the atomizing module 5 is placed in the accommodating cavity 14, the air outlet 52 of the atomizing bottle 51 is connected with the air outlet hole 143. In addition, the atomizing bottle 51 is provided with a telescopic electrode 55 connected with the atomizer 54, which can be in contact with the electrode in the accommodating cavity 14 to supply power to the atomizer 54.

[0032] In order to ensure the normal operation of the air pump, the delivery module 3 further comprises an air pressure measuring instrument 34. The air pipe 32 is divided into two sections, and the two sections of the air pipe 32 are connected through a three-way joint 35. The remaining interface of the three-way joint 35 is connected with the air pressure measuring instrument 34 through a connecting pipe. The air pump 31 can stop working according to the air pressure value exceeding the threshold value fed back by the air pressure measuring instrument 34 during operation. The air pressure is detected because the air pressure is related to the moving distance of the piston 24. The internal liquid discharge amount and the remaining amount of the liquid storage bottle 21 can be obtained by detecting the air pressure. The liquid discharge amount can be indicated based on the air pressure signal, so as to accurately control the liquid spraying amount. In addition, when the nutrient solution in the liquid storage bottle 21 is used up, the air pump 31 will continue to work, which will cause the air pressure in the liquid storage bottle 21 to rise. When the air pressure measuring instrument 34 detects that the air pressure exceeds the threshold value, it is judged that the nutrient solution is used up. The air pump 31 can stop working according to the signal, so as to avoid damage to the air pump 31 or other components. The user can also be reminded to supplement the nutrient solution in this way. The feedback control is a conventional control technology. According to the actual situation, existing components can be selected. In addition, a first one-way valve 36 which can only open in the direction of the liquid storage bottle 21 or the atomizing bottle 51 is arranged at the end of the air pipe 32 connected with the air inlet 23 or the air inlet 53. When the liquid storage module 2 is placed in the accommodating cavity 14, the first one-way valve 36 can ensure that the piston 24 is pushed to maintain the internal air pressure of the liquid storage bottle 21. The piston 24 is always in the state of pushing the internal liquid to flow out, so as to more accurately control the liquid discharge amount. When the atomizing module 5 is placed in the accommodating cavity 14, the first one-way valve 36 can avoid the reverse entry of the atomizing gas into the air pump 31. The blowing speed of the atomizing gas can be controlled through the air pressure measuring instrument 34.

[0033] Current hair care combs almost never have an internal cleaning function. Because the liquid-guiding holes inside the comb teeth are small, prolonged use can cause residual liquid to accumulate and clog them. Furthermore, if you switch to a different type of conditioning solution mid-cycle, the residual liquid in the holes will mix with the new liquid, affecting the conditioning effect. Therefore, if... Figure 6 As shown, this utility model also includes a cleaning module 6 inside the housing 1. The cleaning module 6 includes a water pump 61 with an inlet pipe 62 and an outlet pipe 63.

A second one-way valve 331, which can only be opened towards the infusion pipe 33, is provided at the interface connected to the liquid storage module 2. When the hair comb needs to be cleaned after the treatment, the delivery module 3 is turned off first, then the inlet 121 of the hair comb is placed in water, and finally the water pump 61 is turned on to allow clean water to flow through the infusion pipe 33, the liquid guiding channel 45, and the liquid guiding comb teeth 44, flushing out the residual nutrient solution inside, thus achieving a cleaning effect. The second one-way valve 331 can prevent water from entering the liquid storage module 2 during cleaning.

The rear half of the upper shell 11 and the lower shell 12 are spliced ​​together to form a handle 13. The conductive tail cap 19 is located at the tail of the handle 13. The conductive tail cap 19 can be a sleeve-like structure that is sleeved on the tail of the handle 13 for easy installation and at the same time can play a certain role in fixing the handle 13.

[0035] To protect the comb tooth module 4, this utility model also provides a comb tooth cover 49, such as... Figure 1 , Figure 3 As shown, the comb cover 49 is fitted around the comb module 4.
