The user can choose a lower air outlet temperature at the beginning of drying, but this will result in a longer drying time and lower drying efficiency.

[0004] Therefore, there is a need for a new solution.

[0027] For the purpose of facilitating the understanding of the present application, a more complete understanding of the present application will be provided by reference to the accompanying drawings. The exemplary embodiments of the present application are illustrated in the drawings. However, the present application can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

[0029] Embodiment One

[0030] To achieve the above-mentioned purpose, the present application provides a hair dryer with a liquid water sensing unit. Referring to Figs. 1-3, the hair dryer comprises a main body 01, which comprises an air inlet 02, an air outlet 03, a fan 04, a heating element 05, and a control unit 09. The flowing air 30 enters the main body 01 from the air inlet 02, and is blown out from the air outlet 03 after being heated by the fan 04 and the heating element 05. The control unit 09 is connected to the fan 04 and the heating element 05, and comprises an automatic control system for controlling the working of the fan 04 and the heating element 05, so as to control the speed and / or temperature of the flowing air 30, wherein the speed of the flowing air is controlled by controlling the fan, and the temperature of the flowing air is controlled by controlling the heating element.

[0031] Specifically, in the present embodiment, the main body 01 further comprises a hair treatment portion 08 for contacting the hair 07. The hair treatment portion 08 comprises a liquid water sensing unit 10 connected to the automatic control system. The liquid water sensing unit can measure the liquid water W content of the hair surface 71 contacting therewith, and the automatic control system controls the operation of the fan and the heating element to change the speed or / and temperature of the flowing air 30 according to the change of the liquid water content. Further, the liquid water sensing unit comprises a sensing area 90, and the automatic control system changes the speed or / and temperature of the flowing air 30 according to the change of the liquid water content of the hair surface 71 detected in the sensing area 90. The hair dryer provided in the present embodiment is equipped with a liquid water sensing unit, which measures the liquid water content of the hair surface in the sensing area, and changes the speed or / and temperature of the flowing air blown by the hair dryer according to the change of the detected liquid water content, so as to automatically adjust the outlet air temperature in real time according to the dryness of the hair, thereby avoiding the hair damage caused by the initially set outlet air temperature that is too high during the drying process, and improving the user experience.

[0032] Specifically, in an embodiment of the present application, the liquid water sensing unit comprises a first contact 110 and a second contact 210 for contacting the liquid water W of the hair surface 71. The first contact 110 and the second contact 210 are respectively connected to a control unit 09, and the area between them serves as a sensing area 90. The control unit 09 changes the speed or / and temperature of the flowing air 30 according to the change of the liquid water W content of the hair surface 71 detected between the first contact 110 and the second contact 210. Further, the liquid water sensing unit 10 contacts two different positions of the same bundle of hair 07, the first contact 110 contacts the hair at a position relatively far from the hair end 72, and the second contact 210 contacts the hair at a position relatively close to the hair end 72. By using at least two contacts to contact the hair at different positions, the change of the liquid water content of the hair surface can be more accurately detected. In this way, even if the wetness of the hair differs at different positions, it can be more comprehensively perceived and adjusted accordingly. Since the control unit adjusts the wind temperature and speed according to the change of the liquid water content in the sensing area, the wind temperature can be effectively matched with the liquid water content of the hair surface, so as to avoid damaging the hair due to the excessively high wind temperature, and to ensure that sufficient heat is provided when the hair is particularly wet to accelerate the drying speed and reduce the drying time.

[0033] Specifically, in one embodiment of the present application, the automatic control system detects the change of the liquid water content of the hair surface 71 in the sensing area 90 while controlling the flow air 30 to blow to the hair surface 71, and if the liquid water content of the hair surface in the sensing area decreases, the speed or / and temperature of the flow air 30 is decreased accordingly; if the liquid water content of the hair surface in the sensing area increases, the speed or / and temperature of the flow air 30 is increased accordingly. Thus, the automatic adjustment of the air temperature according to the moisture level of the hair in the sensing area can be realized, and the problem of the hair being damaged by too high air temperature or the problem of the efficiency being affected by too low air temperature can be effectively solved.

[0034] Further, in this embodiment, the automatic control system detects the decrease of the liquid water content of the hair surface 71 in the sensing area 90 during the continuous blow-drying process when the sensing area 90 stays at the same position of the hair surface 71, and the speed or / and temperature of the flow air 30 is decreased accordingly to avoid damaging the hair during the blow-drying process at the same position.

[0035] Further, in this embodiment, the automatic control system increases or decreases the speed or / and temperature of the flow air 30 according to the increase or decrease of the liquid water content of the hair surface 71 in the sensing area 90 when the sensing area 90 moves on the hair surface 71, and stops increasing or decreasing the speed or / and temperature of the flow air 30 when the sensing area 90 separates from the hair.

[0036] Further, in this embodiment, the flow air includes the flow air 30 in the sensing area, and after the automatic control system detects the change of the liquid water content of the hair surface 71, the speed or / and temperature of the flow air 30 in the sensing area is changed according to the change of the liquid water content in the sensing area 90, while the speed or / and temperature of the flow air 30 outside the sensing area is not adjusted. Thus, only the flow air in the sensing area is adjusted, and the flow air in other areas is not affected, and the control of the blow-drying process of the hair can be more accurate.

[0037] Further, in the embodiment, as shown in FIG. 1, the first contact 110 and the second contact 210 are long contact surfaces, each of which includes a proximal end and a distal end, i.e., the first contact 110 includes a first contact proximal end 111 and a first contact distal end 112, and the second contact 210 includes a second contact proximal end 211 and a second contact distal end 212, and the sensing area 90 at least includes an area between the four points of the first contact proximal end 111, the first contact distal end 112, the second contact proximal end 211 and the second contact distal end 212. The contact member formed by the long contact surface ensures that the liquid water sensing unit can cover a wide area of the hair surface, so as to more accurately perceive the change of the liquid water content on the hair surface, so as to make more accurate adjustment during the hair blowing process, and realize more effective hair blowing effect.

[0038] Specifically, in the embodiment, the first contact and the second contact are heating members. The first contact 110 and the second contact 210 can heat the hair surface 71 after being heated to a surface temperature higher than the temperature of the hair surface; when the automatic control system detects the change of the liquid water content of the hair surface 71, the first contact 110 and the second contact 210 are heated by the hot air, and at the same time, the liquid water on the hair surface 71 is heated. By integrating the heating member into the liquid water sensing unit, the state change of the hair surface can be more effectively perceived, and corresponding heating control can be provided when needed, so as to ensure that the hair can be quickly and uniformly dried.

[0039] Specifically, in the embodiment, as shown in FIG. 4, the main body 01 includes a first end 51, a second end 52 and a handle 54, the handle 54 is arranged between the first end 51 and the second end 52; the air inlet 02 is arranged at the first end 51, the hair treatment part 08 is arranged at the second end 52, the air outlet 03 is arranged at the hair treatment part 08, and the first contact 110 and the second contact 120 are adjacent to the air outlet 03.

[0040] The hair dryer provided in the embodiment realizes automatic adjustment of the air outlet temperature according to the humidity of the hair through the liquid water sensing unit, thereby improving the user experience, avoiding damage to the hair, and improving the drying efficiency.

[0041] Embodiment Two

[0042] The difference between the embodiment and the embodiment one is that, as shown in FIG. 5 and FIG. 6, the liquid water sensing unit (10) further includes at least one contact tooth arranged on the first contact (110) and at least one contact tooth arranged on the second contact (210), each of the contact teeth includes a contact tooth end and a contact tooth bottom, the change of the liquid water content of the hair surface (71) is detected through the part between the contact tooth end and the contact tooth bottom, and the area between the contact tooth ends and the contact tooth bottoms of the plurality of contact teeth constitutes the sensing area (90).

[0043] Specifically, when each contact member is provided with one contact tooth, i.e. the first contact member 110 is provided with the first contact tooth 120 and the second contact member is provided with the second contact tooth 220, the sensing area 90 includes the area between the first contact tooth 120 and the second contact tooth 220. Further, the first contact tooth 120 includes a first contact tooth end 121 and a first contact tooth bottom 122, and the second contact tooth 220 includes a second contact tooth end 221 and a second contact tooth bottom 222, and the part of the contact tooth for detecting the change of the liquid water content of the hair surface 71 includes the part between the contact tooth end and the contact tooth bottom, i.e. the sensing area 90 includes the area between the first contact tooth end 121, the first contact tooth bottom 122, the second contact tooth end 221 and the second contact tooth bottom 222.

[0044] Specifically, when each contact member is provided with one contact tooth, i.e. the first contact member 110 is provided with the first contact tooth 120 and the second contact member is provided with the second contact tooth 220, the sensing area 90 includes the area between the first contact tooth 120 and the second contact tooth 220. Further, the first contact tooth 120 includes a first contact tooth end 121 and a first contact tooth bottom 122, and the second contact tooth 220 includes a second contact tooth end 221 and a second contact tooth bottom 222, and the part of the contact tooth for detecting the change of the liquid water content of the hair surface 71 includes the part between the contact tooth end and the contact tooth bottom, i.e. the sensing area 90 includes the area between the first contact tooth end 121, the first contact tooth bottom 122, the second contact tooth end 221 and the second contact tooth bottom 222.

[0045] The present embodiment combines the sensing part and the comb teeth by the contact tooth provided on the contact member, so that the detection process can be more coordinated with the action of combing the hair. When combing the hair or moving the hair dryer to different hair positions at will, the contact tooth can be in direct contact with the hair surface, is not disturbed by the external environment, and can more effectively measure the amount and change of the liquid water on the hair surface (71). Therefore, the measurement accuracy can be further improved, the measurement error can be reduced, and the user experience can be improved.

[0046] Embodiment Three

[0047] The difference between this embodiment and embodiment two is that in this embodiment, a movable structure is further provided between the first contact member 110 and the second contact member 210, for changing the distance between the contact tooth end of the first contact member 110 and the contact tooth end of the second contact member 210, and the shape or / and size of the sensing area changes according to the distance between the first contact member 110 and the second contact member 210.

[0048] Specifically, in this embodiment, as shown in FIG. 9 and FIG. 10, the distance between the first contact tooth end 121 and the second contact tooth end 221 can be changed from an initial distance D1 to a post-moving distance D2, where the post-moving distance D2 is longer than the initial distance D1. Since the distance between the contact tooth ends can be changed, the sensing area is a variable sensing area, and the shape or / and size of the sensing area changes according to the distance between the first contact member 110 and the second contact member 210, i.e. when the distance between the first contact tooth end 121 and the second contact tooth end 221 increases, the sensing area range increases. When the hair is placed between the first contact tooth end 121 and the second contact tooth end 221, and the distance is increased from the initial distance D1 to the post-moving distance D2, the automatic control system starts to change the speed or / and temperature of the flowing air 30 according to the change of the liquid water content in the sensing area; when the hair is away from between the first contact tooth end 121 and the second contact tooth end 221, and the distance is shortened from the post-moving distance D2 to the initial distance D1, the automatic control system stops to change the speed or / and temperature of the flowing air 30 according to the change of the liquid water content in the sensing area.

[0049] In this embodiment, the distance between the contact members is changed by the movable structure, and the shape and size of the sensing area can be dynamically adjusted according to the change of the distance between the contact tooth ends, so that the speed or temperature of the flowing air can be more accurately controlled to meet the requirements under different conditions.

[0050] Embodiment four

[0051] The difference between this embodiment and embodiment one or two is that the liquid water sensing unit includes at least two groups of sensing areas, such as the first sensing area 91 and the second sensing area 92 shown in FIG. 11; the main body includes at least two air outlets, such as the first air outlet 33 and the second air outlet 34 shown in FIG. 11; and the flowing air is blown out from the at least two air outlets in different directions, such as the flowing air 30 is blown from the first air outlet 33 to the first sensing area 91, and the flowing air 30 is blown from the second air outlet 34 to the second sensing area 92.

[0052] Further, in the present embodiment, the hair treatment part 08 is a columnar member, which comprises at least two sets of curved surfaces arranged at different positions of the columnar member, such as the first set of curved surfaces 18 and the second set of curved surfaces 19 shown in Fig. 11; each set of curved surfaces is provided with a set of sensing areas and an air outlet, such as the first air outlet 33 and the first sensing area 91 arranged at the first set of curved surfaces 18, and the second air outlet 34 and the second sensing area 92 arranged at the second set of curved surfaces 19, the first air outlet 33 blows the first set of flowing air through the first sensing area 91, and the second air outlet 34 blows the second set of flowing air through the second sensing area 92.

[0053] In the present embodiment, the multiple sets of sensing areas and air outlets are arranged to allow the hair at different positions to be treated respectively, and the combination of each set of sensing areas and air outlets can be used to accurately detect the moisture content and dry the hair at different hair regions, thus providing more flexible and accurate hair treatment functions.

[0054] Embodiment Five

[0055] The difference between the present embodiment and the embodiments one to four is that the first contact 110 and the second contact 210 are conductive members, i.e. the first conductive member and the second conductive member; the control unit 09 comprises two different electrodes connected with the first contact 110 and the second contact 210 respectively; and the automatic control system measures the resistivity between the first contact 110 and the second contact 210 to determine the change of the liquid water W content on the hair surface 71.

[0056] Specifically, in the present embodiment, the automatic control system detects the change of the liquid water content on the hair surface 71 between the first conductive member and the second conductive member according to the change of the resistivity between the first conductive member and the second conductive member; the automatic control system changes the speed or / and temperature of the flowing air according to the detected change of the resistivity between the first conductive member and the second conductive member; when the detected resistivity between the first conductive member and the second conductive member decreases, the speed or / and temperature of the flowing air is increased correspondingly; when the detected resistivity between the first conductive member and the second conductive member increases, the speed or / and temperature of the flowing air is decreased correspondingly. The automatic control system comprises a preset resistivity range, when the detected resistivity between the first conductive member and the second conductive member is lower than the preset resistivity range, the speed or / and temperature of the flowing air is increased correspondingly; when the detected resistivity between the first conductive member and the second conductive member is higher than the preset resistivity range, the speed or / and temperature of the flowing air is decreased correspondingly.

[0057] In this embodiment, the first contact and the second contact are electrically conductive, and the resistivity between the two changes when the liquid water content of the hair surface in contact with them changes, thus the change in the liquid water content of the hair surface can be reflected according to the change in the resistivity between the two, a more effective measurement of the liquid water content change, and a more effective control of the hair treatment process.

[0058] Embodiment Six

[0059] The difference between this embodiment and Embodiment One is that the main body 01 includes a first end 51 and a second end 52, the air inlet 02 is arranged at the first end 51, the hair treatment part 08 is arranged close to the second end 52, and the air outlet 03 is arranged at the hair treatment part 08, and the first contact 110 and the second contact 210 extend from the air outlet 03 to the main body 01.

[0060] Specifically, in this embodiment, the hair treatment part 08 includes a first air outlet and a second air outlet, the liquid water sensing unit 10 extends the first contact from the main body in the first air outlet and extends the second contact from the main body in the second air outlet, and the flowing air is blown out from the first air outlet and the second air outlet, passes through the hair surface 71 in the sensing area 90, and reduces the liquid water content of the hair surface 71 between the first contact 110 and the second contact 210.

[0061] By arranging the position of the contact to extend from the air outlet to the main body, the flowing air can effectively pass through the hair surface, the reduction of the liquid water content of the hair surface is achieved, and the drying efficiency is improved.

[0062] Embodiment Seven

[0063] The difference between this embodiment and Embodiment One is that the main body 01 includes a first end 51 and a second end 52, the air inlet 02 is arranged at the first end 51, the hair treatment part 08 is arranged at the second end 52, and the air outlet 03 is arranged between the first end 51 and the second end 52, and the flowing air 30 is blown out from the air outlet 03 and blown to the hair treatment part 08 outside the main body 01 and enters the sensing area 90.

[0064] Embodiment Eight

[0065] The difference between this embodiment and the above embodiments is that, as shown in FIG. 14, the main body further includes a comb tooth 11, the hair treatment part 08 includes at least three comb teeth, the comb tooth includes a comb tooth end 12 and a comb tooth bottom 13, the comb tooth bottom 13 is arranged at the hair treatment part 08, and the first contact 110 and the second contact 210 are arranged between two comb teeth.

[0066] Further, in this embodiment, the comb teeth or / and the comb tooth end 12 are insulating members, and the first contact member 110 and the second contact member 210 are conductive members. The comb tooth end 12 is arranged outside the sensing area 90, i.e. the comb tooth end is an isolator, and is used between the scalp and the sensing area 90. When the automatic control system detects the change in the liquid water content of the hair surface 71, the comb tooth end 12 is in contact with the scalp, and separates the first contact member 110 and the second contact member 210 from the scalp; the flowing air 30 is blown out from the air outlet, first passes through the sensing area 90, then passes through the comb tooth end 12, and then reaches the scalp. In this way, while ensuring good contact between the contact member and the hair, the comb tooth separates the scalp from the contact member, avoiding direct contact between the conductive member and the scalp, and between the conductive member and the conductive member, thereby ensuring safety.

[0067] Further, as shown in FIG. 11, when the hair treatment part 08 includes at least two groups of sensing areas, the comb teeth 11 are arranged between the contact teeth of each group of sensing areas, separating the scalp 14 from the sensing areas, and also separating the two groups of sensing areas, so that the automatic control system can more accurately monitor the change in the liquid water content of different sensing areas, without being affected by other areas, to further improve the accuracy of detecting the change in the liquid water content of different sensing areas.

[0068] Embodiment Nine

[0069] The difference from Embodiment Eight is that, in this embodiment, the hair treatment part 08 further includes an elastic member 15, and the comb tooth bottom 13 is arranged in the elastic member; the air outlet 03 is an elastic member air outlet, and the liquid water sensing unit is arranged to extend outward from the main body in the elastic member air outlet.

[0070] Specifically, in this embodiment, as shown in FIG. 15, the elastic member 15 includes a first elastic member fluid outlet 16 and a second elastic member fluid outlet 17, the first contact member 110 extends out of the first elastic member fluid outlet 16, and the second contact member 210 extends out of the second elastic member fluid outlet 17. The elastic member 15 includes a static state and a pressed state, and the area of the liquid water sensing unit exposed outside the main body changes according to the state of the elastic member 15; when the elastic member is in the static state, the exposed area of the liquid water sensing unit is relatively small, and when the elastic member is in the pressed state, the exposed area of the liquid water sensing unit is relatively large.

[0071] In this embodiment, the first contact member 110 and the second contact member 210 extend out of the main body from the first elastic member fluid outlet 16 and the second elastic member fluid outlet 17 respectively, thereby realizing the extension and contraction of the liquid water sensing unit, adjusting the exposed range of the liquid water sensing unit to adapt to different treatment requirements.

[0072] Embodiment Ten

[0073] The difference between this embodiment and embodiment eight is that, in this embodiment, the hair treatment part 08 further comprises an air diffuser 55, which comprises a disc-shaped air diffusion surface, and the comb teeth 11 and the liquid water sensing unit are arranged on the disc-shaped air diffusion surface; the disc-shaped air diffusion surface comprises a disc-shaped curved surface 56 that is curved towards the main body.

[0074] In this embodiment, by arranging the disc-shaped air diffusion surface in the air diffuser, when the air passes through the disc-shaped air diffusion surface, the disc-shaped curved surface that is curved towards the main body will cause the air flow to bend and diffuse, thereby forming a more uniform and soft air flow field, and achieving more effective control of the direction and speed of the air flow. Therefore, not only can the efficiency and effect of hair treatment be improved, but also the user experience can be improved.

[0075] Embodiment eleven

[0076] The difference between this embodiment and the above-mentioned embodiments is that, in this embodiment, the second end 52 is detachable from the main body and becomes a accessory part; the accessory part comprises an accessory connecting end, and the accessory connecting end is provided with an accessory signal port connected with the liquid water sensing unit; the main body comprises a third end 53 engaged with the accessory connecting end, and the third end 53 is provided with a main body signal port connected with the automatic control system. After the accessory part is connected with the main body, the accessory signal port is engaged with the main body signal port, and the liquid water sensing unit is connected with the automatic control system.

[0077] Embodiment twelve

[0078] The difference between this embodiment and embodiments one to eleven is that, in this embodiment, in order to achieve better blowing effect, the blowing efficiency can be improved by reasonably setting the distance between the hair dryers, that is, the main body 01 further comprises a distance measuring part connected with the automatic control system, which is used to measure the distance between the liquid water sensing unit and the hair surface 71; when the distance between the liquid water sensing unit and the hair surface 71 is less than a preset distance value, the automatic control system starts to change the speed or / and temperature of the flowing air 30 according to the change of the content of the liquid water W in the sensing area; when the distance between the liquid water sensing unit and the hair surface 71 is greater than the preset distance value, the automatic control system stops changing the speed or / and temperature of the flowing air 30 according to the change of the content of the liquid water W in the sensing area. When the distance between the sensing area and the hair is too large, the content of the liquid water in the sensing area may no longer accurately reflect the actual situation of the hair surface, and therefore adjusting the speed and temperature of the dryer may become ineffective or inaccurate.
