Description

TECHNICAL FIELD

[0001] The present disclosure relates to a hair care appliance. BACKGROUND

[0002] The background section provided herein is merely for information and is not necessarily prior art.

[0003] With the improvement of people's living standards, multi-functional styling appliances (such as curling irons, straightening irons, etc.) as daily necessities can be used to dry or simply curl and straighten hair, and can be used by the user to hold the multi-functional styling appliance to dry and style hair, which is very convenient.

[0004] The multi-functional styling appliance can be used as a hair dryer and as a styling appliance (e.g. curling, straightening, etc.). Generally, the multi-functional styling appliance provides a gas flow through an extended gas flow path through a heating assembly to produce hot air at an outlet, thereby enabling the multi-functional styling appliance to dry and style hair.

[0005] The multi-functional styling appliances in the prior art have a fixed overall shape and are mostly straight rod structures, which cannot be bent and are inconvenient to store and operate. Moreover, when the user operates these multi-functional styling appliances and processes hair with the multi-functional styling appliances, the hand holding position is high and the center of gravity is not ergonomic, which can easily cause fatigue after a long time of use.

[0006] There are multi-functional styling appliances in the prior art that can be used in a straight and a bent state by a rotating end face bending method. However, such multi-functional styling appliances at least have the following disadvantages: 1. the multi-functional styling appliance is relatively hard after being bent, which is less acceptable to female users; 2. the multi-functional styling appliance forms a bent air duct after being bent, which is not convenient for gas flow, requires a larger power motor, and makes the multi-functional styling appliance cost higher; 3. the multi-functional styling appliance has a large noise, and considering that the multi-functional styling appliance needs to be close to the user's ear during use, the user's experience is poor; 4. rotating the end face by 180 degrees will pull and twist the internal wiring, reducing the service life of the wiring harness.

[0083] The present disclosure will be further described in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are merely intended to explain the relevant content, and not to limit the present disclosure. In addition, it should be noted that, for the convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0084] It should be noted that the embodiments and features of the embodiments in the present disclosure can be combined with each other in the case of no conflict. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0085] Unless otherwise specified, the example embodiments / instances shown will be understood as providing exemplary features of various details that can implement the technical concepts of the present disclosure in practice. Therefore, unless otherwise specified, the features of various embodiments / instances can be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of the present disclosure.

[0086] In the drawings, cross-hatching and / or shading are generally used to indicate that a portion of one feature can be located structurally close to another, even though not directly visible. As such, unless stated otherwise, the presence of cross-hatching or shading is not meant to imply that a specific material, material property, dimension, ratio, etc., is being represented other than that which might be explicitly stated. In addition, for purposes of clarity and / or description, dimensions and / or relative dimensions shown in the figures can have been exaggerated relative to other elements. When example embodiments can be practiced differently, a specific process sequence can be performed in a different order than the described order or sequentially. For example, two consecutively described processes can be performed at substantially the same time or in the reverse order of the described order. Moreover, like reference numerals designate like elements throughout the several views.

[0087] When a component is referred to as being "on" or "over" another component, "connected to" or "coupled to" another component, it can be directly on, directly connected to, or directly coupled to the other component, or one or more intervening components can be present. However, when a component is referred to as being "directly on", "directly connected to", or "directly coupled to" another component, there are no intervening components present. To this end, the term "connected" can refer to a physical or electrical connection, with or without intervening components.

[0088] For descriptive purposes, the disclosure can use spatially relative terms, such as "below," "lower," "under," "downward," "down," "above," "upper" and "over," to describe the relative position of one component to another as illustrated in the figures. Unless otherwise specified, these spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, elements described as "below" or "under" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. Moreover, the device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0089] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms "including," "includes," "having," "has," "with," or variants thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term "comprising." It is also noted that the terms "substantial," "approximately," and other similar terms, as used herein, are used in a relative sense and not in an absolute sense. Thus, they are used to explain that a value, calculation, and / or provided value is close to an intended value, calculation, and / or provided value, respectively, as would be recognized by one of ordinary skill in the art.

Figure 2 is a structural schematic view of another angle of a longitudinal counter-rotation state of a hair care appliance according to an embodiment of the present disclosure. Figure 3 is a structural schematic view of a relative bending state of a hair care appliance according to an embodiment of the present disclosure. Figure 4 is a structural schematic view of another angle of a relative bending state of a hair care appliance according to an embodiment of the present disclosure. Figure 5 is a structural schematic view of a hair care appliance according to an embodiment of the present disclosure.

[0091] As Figures 1 to 5As shown, the hair care device of this disclosure may include components such as a handle portion 100, a main body portion 200, and a connector assembly 300. When using the hair care device of this disclosure, the user can hold the handle portion 100 with the free end of the main body portion 200 facing the hair. At this time, gas can enter the interior of the handle portion 100 through a through-hole, and after flowing through the handle portion 100, the connector assembly 300, and the main body portion 200, the gas is discharged from the free end of the main body portion 200. Correspondingly, since a heater 400 is provided inside the main body portion 200, hot air can be provided to the user through the main body portion 200.

[0092] Specifically, both the main body 200 and the handle 100 of this disclosure are cylindrical and have approximately equal outer diameters, thereby allowing the hair care device of this disclosure to be easily stored and held by the user. The central axis of the handle 100 is formed as the longitudinal axis of the handle 100. Alternatively, the main body 200 may also include a central axis. In various implementations of this disclosure, the handle 100 is generally vertically positioned.

[0093] like Figure 5 As shown, the hair care appliance disclosed herein may also include components such as a heater 400, a rectifier 500, a motor 600, a fan, a printed circuit board, and a user interaction device 700.

[0094] The heater 400 is disposed within the main body 200, and accordingly, when gas flows through the heater 400, the heater 400 can heat the gas. In one specific embodiment, the heater 400 may include multiple resistance wires. Of course, the heater 400 of this disclosure can also be implemented using other types of heating elements.

[0095] A rectifier 500 is disposed inside the main body 200, along the flow direction of the gas in the hair care device. The rectifier 500 is located upstream of the heater 400, so that the gas passes through the rectifier 500 and is rectified by the rectifier 500 before flowing through the heater 400. Thus, the gas can flow evenly through the heater 400 and be heated evenly by the heater 400, thereby improving the temperature distribution uniformity of the hot air discharged from the main body 200.

[0096] A motor 600 and a fan (not shown) are disposed within the handle portion 100. The motor 600 drives the fan to rotate, thereby forcing gas flow within the gas flow path. The motor 600 and the fan are positioned within the handle portion 100 close to the connector assembly 300, so that when the motor 600 rotates, the gas drawn in by the fan can flow into the connector assembly 300 along the shortest possible path and then flow through the connector assembly 300 to the main body portion 200, thereby reducing gas loss during the flow process.

[0097] In the present disclosure, a printed circuit board (not shown in the figures) is located within the handle portion 100 and is positioned closer to the joint assembly 300 than to the motor 600 and the fan; thus, the air sucked via the motor 600 and the fan can flow through the printed circuit board, thereby cooling the electronic components on the printed circuit board, improving the service life of the printed circuit board.

[0098] The user interaction device 700 is provided on the handle portion 100. In one specific embodiment, the user interaction device 700 can be a button, and the user operates the hair care appliance by triggering the button. In the present disclosure, the projection (projection in the plane of the longitudinal axis) of the user interaction device 700 does not coincide with the projection (projection in the plane of the longitudinal axis) of the motor 600, so that the user does not directly hold the area where the motor is located, reducing the influence of the vibration generated by the motor on the user, improving the user experience.

[0099] Holes are formed on the handle portion 100, and the gas inlet of the handle portion 100 is formed through the holes, and the gas inlet of the handle portion 100 does not intersect with the user interaction device 700, so that when the user holds the handle portion 100, the user's hand will not cover the holes, thereby not affecting the gas entering the handle portion 100.

[0100] In a preferred embodiment, the length of the main body portion 200 is about 1 / 4 of the total length of the hair care appliance; that is, the main body portion 200 of the present disclosure has a relatively short size, thereby facilitating the user to hold the hair care appliance, improving the user experience.

[0101] In the present disclosure, as shown in Figures 1 to 4 The handle portion 100 and the main body portion 200 are pivotally coupled to each other through the joint assembly 300, so that the main body portion 200 and the handle portion 100 are in longitudinal alignment or the main body portion 200 and the handle portion 100 are relatively bent. Specifically, as shown in Figure 1 and Figure 2 When the handle portion 100 and the main body portion 200 are in longitudinal alignment, the central axis of the handle portion 100 is arranged substantially vertically, and the central axis of the main body portion 200 is arranged substantially coinciding with the central axis of the handle portion 100. As shown in Figure 3 and Figure 4 When the handle portion 100 and the main body portion 200 are in relative bending, an included angle is formed between the central axis of the handle portion 100 and the central axis of the main body portion 200, which is the first angle described below. In one specific embodiment, the first angle can be greater than or equal to 85° and less than or equal to 180°.

[0102] The handle portion 100 and the body portion 200 have a gas flow path extending through the handle portion 100 and the body portion 200 from a gas inlet in the handle portion 100 to a gas outlet in the body portion 200; when gas flows along the gas flow path, the gas flows through the handle portion 100, the joint assembly 300 and the body portion 200 in turn, and is discharged from the gas outlet on the free end of the body portion 200.

[0103] The structure of the joint assembly 300 will be described in detail below in conjunction with the drawings.

[0104] Figure 6 is a structural schematic diagram of a joint assembly of a hair care appliance according to an embodiment of the present disclosure. Figures 7 to 9 is a structural schematic diagram of a joint assembly of a hair care appliance according to an embodiment of the present disclosure. Figure 10 is a structural schematic diagram of a body joint 320 of a hair care appliance according to an embodiment of the present disclosure. Figure 11 is a structural schematic diagram of a handle joint 310 of a hair care appliance according to an embodiment of the present disclosure.

[0105] As shown in Figures 6 to 11 , the joint assembly 300 of the present disclosure can include a handle joint 310, a body joint 320 and a flow guide 330 and the like.

[0106] Among them, the handle joint 310 and the body joint 320 can be matched with each other and can be pivotally connected. That is, the handle joint 310 and the body joint 320 of the present disclosure can be rotatably fixed to each other, so that the body portion 200 can be kept in a fixed posture relative to the handle portion 100 at a first angle.

[0107] The handle joint 310 is in gas communication with the handle portion 100, and the body joint 320 is in gas communication with the body portion 200, so that the handle portion 100, the joint assembly 300 and the body portion 200 can jointly form a gas flow path. That is, the handle joint 310 of the present disclosure can be fixed on the handle portion 100, and the body joint 320 can be fixed on the body portion 200, so that based on the pivotal connection between the handle joint 310 and the body joint 320, the body portion 200 can be rotated relative to the handle portion 100.

[0108] In the present disclosure, no matter whether the handle portion 100 and the body portion 200 are in a longitudinal alignment state or a relative bending state, the gas flow path can always be sealed within the handle portion 100, the joint assembly 300 and the body portion 200. That is, at this time, the gas will not leak from the part between the gas inlet of the handle portion 100 and the gas outlet of the body portion 200.

[0109] In addition, the joint assembly 300 of the present disclosure has a transverse width, where the transverse direction is the direction of the pivot axis of the joint assembly 300, and the transverse width is the dimension of the joint assembly 300 in the direction of the pivot axis. Preferably, the transverse width is less than or equal to the outer diameter of the handle portion 100 or the body portion 200, whereby the joint assembly 300 of the present disclosure does not occupy extra storage space, and makes the hair care appliance easier to store.

[0110] The flow guide 330 is configured to maintain a constant position relative to the handle portion 100 in both the longitudinal alignment and the relative bending; whereby the flow guide 330 enables the gas in the gas flow path to be guided so that the gas in the gas flow path does not generate or as little as possible generates turbulence, so that the hair care appliance of the present disclosure has less wind tunnel loss.

[0111] In a preferred embodiment, the flow guide 330 is formed in the handle joint 310; in the present disclosure, the flow guide 330 is configured to guide the gas to flow through the heater 400; that is, in the direction of the flow of the gas in the gas flow path, the flow guide 330 is located on the upstream side of the heater 400.

[0112] To achieve efficient guiding of the gas in the gas flow path, the flow guide 330 of the present disclosure extends in a direction inclined to the longitudinal axis; specifically, the flow guide 330 of the present disclosure is inclined to the longitudinal axis in the direction of the flow of the gas in the gas flow path; in other words, the flow guide 330 of the present disclosure is inclined to the longitudinal axis in the direction from upstream to downstream of the gas in the gas flow path.

[0113] In the present disclosure, the flow guide 330 is configured to guide the gas to flow through at least one side of the gas outlet of the handle portion 100 to the gas inlet of the body portion 200. More preferably, there are two flow guides 330, and the flow guides 330 are configured to guide the gas to flow through both sides of the gas outlet of the handle portion 100 to the gas inlet of the body portion 200.

[0114] Figure 12 is a cross-sectional structural schematic view of a joint assembly of a hair care appliance according to an embodiment of the present disclosure (longitudinal alignment state). Figure 13 is a structural schematic view of a sealing cover plate 340 of a hair care appliance according to an embodiment of the present disclosure. Figure 14 is a cross-sectional structural schematic view of a joint assembly of a hair care appliance according to an embodiment of the present disclosure (relative bending state). Figure 15 and Figure 16 are structural schematic views of a handle joint of a hair care appliance at different angles according to an embodiment of the present disclosure.

[0115] As Figures 6 to 16As shown, the handle connector 310 of this disclosure includes a first connector component 311 and a second connector component 312. The first connector component 311 and the second connector component 312 are fixedly connected by a connecting assembly 313, so that the first connector component 311 and the second connector component 312 are relatively stationary. That is to say, the handle connector 310 of this disclosure is not integrally formed, but is formed as discrete components and is manufactured by assembling these discrete components together.

[0116] In a preferred embodiment, the first connector component 311 and the second connector component 312 are formed in a generally symmetrical structure and are symmetrically arranged on both sides of the main connector 320.

[0117] like Figure 15 and Figure 16 As shown, the first connector component 311 of this disclosure includes a first base 311A ​​and a first ring component 311B connected to the first base 311A. Similarly, the second connector component 312 includes a second base 312A and a second ring component 312B connected to the second base 312A. Accordingly, the first base 311A ​​of the first connector component 311 and the second base 312A of the second connector component 312 can jointly form a gas inlet of the connector assembly 300, which can be connected and communicated with the gas outlet of the handle portion 100, so that the gas flowing in the handle portion 100 can enter the connector assembly 300. That is, both the first base 311A ​​and the second base 312A of this disclosure can be fixed to the handle portion 100.

[0118] Furthermore, the first connector component 311 also includes a first shielding portion 311C, which is connected to the first base 311A ​​and located near the longitudinal axis. Similarly, the second connector component 312 also includes a second shielding portion 312C, which is connected to the second base 312A and also located near the longitudinal axis. Thus, when the first connector component 311 and the second connector component 312 are assembled together, the first shielding portion 311C and the second shielding portion 312C can fit together and work together to block the gas flowing along the longitudinal axis, causing the gas to flow to both sides of the first shielding portion 311C and the second shielding portion 312C. Accordingly, the flowing gas will be divided into a first branch and a second branch. The gas flowing in the first branch will flow into the internal space of the first ring component 311B, and the gas flowing in the second branch will flow into the internal space of the second ring component 312B.

[0119] The flow guide 330 is located in the first ring component 311B. Specifically, the flow guide 330 of the present disclosure can be two, one of which is located in the first ring component 311B, and the other of which is located in the second ring component 312B, so that the gas in the first ring component 311B and the second ring component 312B can be guided by the flow guide 330. In a specific embodiment, the flow guide can be integrally formed with the first joint component 311, and the flow guide can also be integrally formed with the second joint component 312.

Of course, the number of the second limiting component 312E can also be set to other values.

[0123] In the present disclosure, the joint assembly 300 comprises a sealing cover plate 340, which is arranged outside the first ring component 311B of the handle joint 310. In other words, the sealing cover plate 340 of the present disclosure can be provided with two, one sealing cover plate 340 is arranged at the second end of the first ring component 311B, and the other sealing cover plate 340 is arranged at the second end of the second ring component 312B. Thus, by the arrangement of the sealing cover plate 340, gas will not leak outward from the handle joint 310.

[0124] Referring again to Figure 12 In the present disclosure, the inner side of the sealing cover plate 340 is provided with a flow guide part 341, which is arranged close to the flow guide 330, and the flow guide part 341 cooperates with the flow guide 330 to form a flow guide air duct towards the gas inlet of the main body part 200.

[0125] Specifically, the flow guide part 341 can be arranged inside the handle joint 310, for example, the flow guide part 341 can be arranged inside the first ring component 311B of the handle joint 310. And the flow guide surface of the flow guide part 341 is arranged obliquely, so that the flow guide part 341 has substantially the same spacing with the outer side of the flow guide 330.

[0126] In a preferred embodiment, the flow guide 330 is arranged to be inclined towards the direction close to the longitudinal axis in the direction from bottom to top (i.e. in the direction of the flow of gas), similarly, the flow guide surface of the flow guide part 341 is also inclined towards the direction close to the longitudinal axis in the direction from bottom to top (i.e. in the direction of the flow of gas).

[0127] The main body joint 320 of the present disclosure can be integrally formed. For example, the main body joint 320 can be integrally injection molded by plastic material. At the same time, as Figure 10As shown, the main joint 320 of the present disclosure can include a main base 321 and a main ring component 322; wherein the main base 321 can form a gas outlet of the joint assembly 300, which can be connected and communicated with the gas inlet of the main body 200, so that the gas flowing in the joint assembly 300 can enter the main body 200. That is, the main joint 320 of the present disclosure can be fixed on the main body 200.

[0128] In the present disclosure, the first ring component 311B and the main ring component 322 are rotatably connected. Similarly, the second ring component 312B is also rotatably connected with the main ring component 322.

[0129] Specifically, referring to Figure 10 The main ring component 322 of the present disclosure includes a first end and a second end in the axial direction, and an inner flange is formed at both the first end and the second end in the axial direction, and a limiting structure 322A is arranged on the inner flange. In a preferred embodiment, the limiting structure 322A can be a limiting groove, and the number of the limiting grooves is set to four, which are uniformly distributed along the circumference of the inner flange.

[0130] When the handle joint 310 and the main joint 320 are assembled together, the first annular protrusion 311D is rotatably arranged in the inner flange of the first end of the main ring component 322; similarly, the second annular protrusion 312D is rotatably arranged in the inner flange of the second end of the main ring component 322; and the first limiting component 311E and the second limiting component 312E can cooperate with the limiting grooves, and the handle joint 310 and the main joint 320 are kept in a fixed posture at a first angle.

[0131] Based on the above structure, the rotatable fixation of the handle joint 310 and the main joint 320 of the present disclosure means that when the first limiting component 311E and / or the second limiting component 312E is located in the limiting groove, the handle joint 310 and the main joint 320 are kept in a fixed posture at a first angle; in addition, when the handle joint 310 is kept fixed, and a force is applied to the main joint 320, and the force is greater than a preset value to be able to make the first limiting component 311E and / or the second limiting component 312E out of the limiting groove, the handle joint 310 and the main joint 320 can be relatively rotated until the first limiting component 311E and / or the second limiting component 312E enters the limiting groove again, at which time the handle joint 310 and the main joint 320 can be fixed to each other.

[0132] In the present disclosure, the number of the limiting grooves is not limited to two, and can be set to six or eight, etc. Thus, the hair care appliance of the present disclosure can be held at multiple positions relative to the handle portion 100 when in use, thereby facilitating the use of the hair care appliance by the user.

[0133] The connecting assembly 313 of the present disclosure is arranged in a direction parallel to the pivot axis of the joint assembly 300. Thus, the first joint component 311 and the second joint component 312 of the present disclosure can be conveniently inserted and coupled, thereby facilitating the assembly of the hair care appliance.

[0134] Referring again to Figure 1 and Figure 4 In the present disclosure, when the first angle is 0°, a first cross section 350 exists between the outer surfaces of the body joint 320 and the handle joint 310; when the first angle is 90°, a second cross section 360 exists between the outer surfaces of the body joint 320 and the handle joint 310, and the maximum depth of the first cross section 350 is greater than or equal to the maximum depth of the second cross section 360. Thus, the hair care appliance of the present disclosure can be conveniently bent and held in the bent state, and the appearance of the hair care appliance after being bent is more beautiful.

[0135] The hair care appliance of the present disclosure can work in a straight state and a bent state when in use, so as to achieve multi-angle use. When the user uses the hair care appliance to blow the hair, the body portion 200 can be bent relative to the handle portion 100 to form an angle of 90° or other suitable angles with the handle portion 100. When the user uses the hair care appliance to make a curling hairstyle, the body portion 200 can be coaxially arranged with the handle portion 100 in a straight state, thereby facilitating the curling operation. Of course, it is also possible for the user to use the hair care appliance in a straight state to blow the hair, and to use the hair care appliance in a bent state to curl the hair, as long as the user feels comfortable with the angle.
